Upstream reciprocity and the evolution of gratitude 总被引:1,自引:0,他引:1
If someone is nice to you, you feel good and may be inclined to be nice to somebody else. This every day experience is borne out by experimental games: the recipients of an act of kindness are more likely to help in turn, even if the person who benefits from their generosity is somebody else. This behaviour, which has been called ‘upstream reciprocity’, appears to be a misdirected act of gratitude: you help somebody because somebody else has helped you. Does this make any sense from an evolutionary or a game theoretic perspective? In this paper, we show that upstream reciprocity alone does not lead to the evolution of cooperation, but it can evolve and increase the level of cooperation if it is linked to either direct or spatial reciprocity. We calculate the random walks of altruistic acts that are induced by upstream reciprocity. Our analysis shows that gratitude and other positive emotions, which increase the willingness to help others, can evolve in the competitive world of natural selection. 相似文献

Who owns your body and parts removed from it? Can you legally sell your bodily material – or information derived from it? Can you legally prevent other people gaining access to your excised bodily material, including your blood relatives who might need your tissue or genetic information for their own genetic tests? What legal remedies are there if people take or use your bodily material without your consent? And why are the answers to these questions vitally important for scientists? 相似文献

Planning a symposium organized by PhD students is a challenging prospect. Insight from the organizers of three such symposia sheds light on the highs and lows of the experience.When we took on the responsibility for our respective annual PhD symposia (Sidebar A), none of us had any idea how much we would have to learn about organization, management and logistics; how many e-mails would be sent; how many deadlines missed. In the end, however, organizing a PhD symposium was in many ways the most instructive part of our first year as PhD students. We had the opportunity to meet and speak with brilliant scientists and we learnt how to coordinate, plan and execute different tasks efficiently with a good team spirit. Both the contacts we made and the skills we acquired should prove useful in our future careers. If you have the opportunity to get involved in organizing a symposium, we hope our experience will help you in making a start.
Sidebar A | The conferences we organized
The 3rd PhD Symposium in Computational Biology and Innovation hosted at the Conway Institute of Biomolecular and Biomedical Research, University College Dublin, Ireland (5–7 December 2012).The 14th European Molecular Biology Laboratory (EMBL) PhD Symposium hosted at EMBL campus in Heidelberg, Germany (24–27 October 2012).The 8th FinBioNet PhD Symposium: Revolutionary bioscience: from advanced technologies to personalized medicine hosted at the University of Tampere, Finland (2–3 October 2012).Perhaps more than any other kind of meeting, a PhD symposium is a great opportunity for early-stage researchers to be exposed to a broad range of science and to meet fellow PhD students and potential collaborators in a friendly atmosphere. By organizing one, you will contribute both to your own career and to those of everyone involved. Many university graduate programmes and societies encourage the organization of such events.If you have the opportunity to get involved in organizing a symposium, we hope our experience will help you in making a startThe amount of work involved, however, is huge and requires the coordination and cooperation of a committee. Your first step, then, is to recruit that committee. An announcement to pique the interest of local PhD students is a good idea to get started, followed by the cooption of members from different areas, groups and institutes to improve diversity and broaden the committee''s knowledge. It also helps to divide the committee into different teams, and to elect a chair, vice-chair and team leaders to keep things on track. Defining clear responsibilities and setting deadlines is vital, but keep in mind that you will need to be flexible, as committee members might find they have more or less time than they planned. In addition to research, both internships and placements are common during the early phases of a PhD and you might unexpectedly lose core committee members along the way. In our case, losing a committee chair meant that the vice-chair had to take over most of the coordination and invest more time during his or her absence.In general, keep in mind that the people you are working with are not full-time employees. It is unlikely that anyone on the organizing committee has done something similar to this before, and so time must be set aside to bring people on board and get them up to speed. Some of your committee members will prove capable of working independently and will require little management; others might be overwhelmed by the demands of their research and will require assistance and micromanagement.In addition to research, internships and placements are common during the early phases of a PhD and you might unexpectedly lose core committee members…You therefore need to monitor people and be prepared for setbacks. As you will collectively bear responsibility for the symposium, work left undone will often fall to other committee members or to you if you are the chair or vice-chair. Just how much slack you have to pick up will depend on your management skills. As long as you have a plan and a clear overview of what needs to be done, management should be straightforward, if not always easy. A well-managed symposium will be a pleasure to organize. A poorly managed one will become a stressful and unpleasant experience.Dividing the labour correctly is the first crucial step. This should happen as early as possible. Sidebar B lists important categories of tasks that must be managed. Large areas—finance, participants and speakers—will probably need sub-committees of their own, while smaller areas such as website management and design might need only one or two people. A large symposium might require a team of 12 people for speakers alone, with one assigned to each speaker. Ideally you will have previous symposia hosted at your institution to use as a blueprint. If not, contact another institute and ask them for an outline. Above all, each task must have a committee member clearly responsible for it, as ambiguous instructions and diffusion of responsibility will result in inaction. Predicting how much work will be involved is difficult, and it is all too easy to under-estimate, leaving you understaffed on the day of the event. Too many staff is far better than too few, and you will find that the ability to be flexible and reassign people to tricky areas or problems is vital to your success.Sidebar B | Important committee tasks
Speakers—contacting speakers, soliciting abstracts and direct assistance to speakersParticipants—selecting plenary speakers and editing abstracts for the abstract bookFinance—fundraising and book-keepingPR—marketing through e-mails and posters, and securing sponsorsPosters—organizing posters on the day and judging any competitionsCatering—providing food and refreshmentsDesign—designing abstract booklets, posters and logosTransport and accommodation—arranging transport and accommodation for speakers (and participants)Website management—ensuring that the website is updated regularly with information about speakers, sessions and travelWithout the right content—speakers, topics and networking opportunities—no symposium will succeed, whether it is organized by PhD students or seasoned professionals. With a committee formed, the most important task is to decide on a scientific theme and a title for the symposium. It is always good to seek suggestions from your peers and mentors, especially because this will raise awareness that the symposium is going to take place. How you ultimately settle on a theme is down to you, but a voting system might be helpful. Remember, however, that the people organizing the symposium need to be confident in its direction and vision. Once a theme is chosen, the next step should be to set the number of sessions and agree on topics for each of these sessions (Sidebar C).Sidebar C | Deciding on a topic and title for your symposium
- The subject of the symposium should be broader than most academic conferences.You want to avoid competing directly with specialized conferences, and instead appeal to a broad range of PhD students.
- Avoid being vague—at the same time, it is vital that a PhD student in any field will read your poster and think ‘this conference is for me''. Moreover, they will need to be able to convince their group leader of it as well.
- Be aware of competitors—the topics of the symposium should not overlap with symposia that are going to be held around the same time.

A rose may be a rose by any other name, but when you call a dog a poodle it becomes a very different animal than if you call it a bulldog. Both the poodle and the bulldog are examples of dog breeds of which there are >400 recognized worldwide. Breed creation has played a significant role in shaping the modern dog from the length of his leg to the cadence of his bark. The selection and line-breeding required to maintain a breed has also reshaped the genome of the dog, resulting in a unique genetic pattern for each breed. The breed-based population structure combined with extensive morphologic variation and shared human environments have made the dog a popular model for mapping both simple and complex traits and diseases. In order to obtain the most benefit from the dog as a genetic system, it is necessary to understand the effect structured breeding has had on the genome of the species. That is best achieved by looking at genomic analyses of the breeds, their histories, and their relationships to each other. 相似文献

Once you start to read this Editor’s Corner, you might wonder why I have devoted an entire article, albeit a short one, to this topic. Let me assure you there are reasons. First, I want to announce a new policy for the journal that will affect all research papers. Starting with all papers that are not currently in press, we will no longer be asking for geographical locations of research companies that follow the listing of a reagent. In Materials and Methods the authors typically refer to a reagent and then list the company and its location parenthetically. For example, “…p-nitrophenyl phosphate (Sigma-Aldrich, St. Louis, MO).” Instead, we will require catalog numbers. The reason is that it is now quite easy to find a company using the internet, and in fact you rarely need to know the location because it is rare that you would send a written order. On the other hand, knowing the name of the reagent is not always sufficient to narrow down the precise item. For example, if you search for “p-nitrophenyl phosphate” at the Sigma-Aldrich site, you get seven primary choices and it is not at all obvious which one to choose. When my lab uses p-nitrophenyl phosphate for the Pho8?60 assay, we use item N9389, which narrows it down to a precise reagent. Thus, we will start requiring papers to write “…p-nitrophenyl phosphate (Sigma-Aldrich, N9389).Second, I think this is actually a useful change, and one that many journals will start to institute once they see it being done here. The old style of listing the city and state is a relic that is no longer relevant. Furthermore, it is not even clear in the current global marketplace if this is particularly helpful. For example, if I am ordering an item from Roche Applied Science, why would anyone care where it is coming from? It is highly unlikely that a researcher in Germany or Japan is going to order from Roche Applied Science that happens to be based in Indianapolis, IN when there are much closer sites in Mannheim, Germany and Tokyo, Japan. So, do not be surprised when you start to see more and more journals adopting this approach, and remember that you saw it here first. Autophagy—the cutting edge. 相似文献

The following guidelines are useful if you want to "do it with a simple table" (Table IV): First, identify the sensitivity and specificity of the sign, symptom or diagnostic test you plan to use. Many are already in the literature, and subspecialists should either know them for their field or be able to track them down for you. Depending on whether you are considering a sign, a symptom or a diagnostic laboratory test, you will want to track down a clinical subspecialist, a radiologist, a pathologist and so on. Start your table with a total of 1000 patients, as shown in location (a + b + c + d) of panel A. Using the information you have about the patient before you apply the diagnostic test, estimate the patient''s pretest likelihood (prevalence or prior probability) of the target disorder -- let''s say 10%. Take this proportion of the total (100) and place it in location (a + c); the remaining 900 patients go in location (b + d) (panel B). Multiply (a + c) (100) by the sensitivity of the diagnostic test (let''s say 83%) and place the result (83) in cell a and the difference (17) in cell c; similarly, multiply (b + d) (900) by the specificity of the diagnostic test (let''s say 91%) and place the result (819) in cell d and the difference (81) in cell b (panel C). If (a + b) and (c + d) do not add up to 1000, you will know you have made a mistake. You can now calculate the positive predictive value, a/(a + b), and the negative predictive value, d/(c + d), as shown in panel D. You have now reached a level of understanding a fair bit beyond the rule-in/rule-out strategy discussed in part 1 of our series. Furthermore, you can already do more than most clinicians, so you may want to stop here, at least for a while. On the other hand, you may want to go further and learn how to handle slightly more complex tables with multiple cut-off points. In the next article you will find more powerful ways to take advantage of the degree of positivity and negativity of diagnostic test results. 相似文献

A PhD thesis is a project with an established goal and a deadline. As such, the tools, strategies and insight of professional project management can be used effectively to improve both research success and personal well-being.A project is a “temporary endeavour undertaken to create a unique product, service or result” [1]. Although this is a generic definition, it pretty much describes any PhD research project. There are many ways to manage a project effectively and efficiently. Unfortunately, most of us are so busy with our science that we forget about the importance of planning and management to our own success, sanity and health. Instead, we approach our first three years of genuine scientific endeavour wide-eyed and unprepared to juggle the hundreds of tiny balls that make up a PhD. Several techniques from the realm of ‘project management'' might therefore be helpful for PhD students who need to plan and manage the many competing demands that doctoral research can place on them.A PhD comprises both the research itself and the acquisition of skills and knowledge that will facilitate your future career. As such, it is of paramount importance to establish your own objectives early on. For example, alongside dividing your project into work packages—smaller projects that might be discrete or might build on each other—it is also essential to define which so-called transferable skills—additional knowledge and experience that might improve your job prospects—you feel will be of greatest use to you, depending on what you want to do after your PhD. The importance of these skills is becoming more widely recognized and taken far more seriously, and you should find that your supervisor is willing to give you the time to pursue them—your institute or university usually requires that he or she does so. More importantly, you should give yourself the time to invest in these skills, as they are going to be vital to everything you do once your PhD project is over.Doctoral research requires a multitude of skills, most of which you will inevitably lack when you commence your PhD programme. The first step is to identify the gaps in your knowledge to plan what skills on which to focus. This will allow you to acquire them in good time, either through professional activities—shadowing a postdoc, teaching undergraduates, joining journal clubs and blogging—or through both internal and external courses and workshops to improve communication, presentation, writing, networking and other skills. In addition to your planned skills acquisitions, you will also have situations arise, in which you need to acquire new skills quickly. The more you plan training activities and skills acquisition in advance, however, the smoother this aspect will be of your PhD. By way of example, part of my own PhD project relates to statistical analysis of data. An early analysis highlighted several areas in which I had to improve my skills, including hierarchical cluster analysis, principal component analysis and χ2 testing against standard distributions. Having identified these gaps in knowledge early on in my doctoral programme, I could plan ahead accordingly when and how to acquire these skills.The full scope of your PhD project is usually unknown at the outset, and even the direction of your research might well change before you are finished. ‘Rolling wave planning'' is a technique that allows you to take these facts into account and plan the short-term future in detail, with a high-level provision for medium- to long-term activities. For those new to developing project schedules, I advocate a simple five-step approach. First, make an ordered list of high-level activities needed to achieve your goal. Second, expand this list by adding lower-level activities for which you have a detailed understanding of the scope, for example work to be performed in the next six months. You now have a work breakdown structure. Third, turn this work breakdown structure into a dependency-driven list by adding associations between the activities, for example by adding links to precursor activities that need to be completed before another activity can be started. Fourth, estimate the duration of each activity and extrapolate the start and end dates beginning with the first scheduled activity. Finally, as you progress through your research, and the scope of future activities becomes clearer, update the project schedule with these low-level activities as they become known. This approach of generating a hybrid-level project schedule, and updating with detailed activities as the scope becomes clearer, is known as ‘rolling wave planning''.…we approach our first three years of genuine scientific endeavour wide-eyed and unprepared to juggle the hundreds of tiny balls that make up a PhDThere is a range of professional software to help develop project schedules, but there are also various freeware tools available. Alternatively, you can use one of the many word processing or spreadsheet applications to make a simple Gantt chart. Along with the technical scope of your doctoral research, it would also be useful to include milestones that your institution enforces; for example literature review submission, formal progress reports and thesis chapter outlines. Including these in your rolling wave planning will allow you to keep in mind the bigger picture and the formal aspects that must be completed for your PhD, in parallel with the progress you are making towards your specific research subject.It is of course a cliché, but it is true that ‘failing to plan is planning to fail''. Of course the fluid nature of research makes it difficult to estimate accurately the time that it will take to complete various experiments, especially as a novice researcher. I therefore believe that although experiments do overrun and PhD projects can change, developing a project schedule is not a futile activity. By having a plan, even if it is made up of ‘guesstimates'', you can forecast roughly how much time you have left for your research and roughly what you can realistically hope to achieve. After all, without a plan, how can you predict when you will complete your research, submit your thesis and ultimately gain your PhD?Doctoral research requires a multitude of skills, most of which you will inevitably lack when you commence your PhD programmeThe serious consideration of scope is necessary in any project, but even more when you are simultaneously project manager, research scientist and key stakeholder. This raises various crucial questions regarding scope management: what is my doctoral research all about (the goal), and what work do I need to do to meet this goal? Once this has been agreed between you and your supervisor(s), it is essential to manage the scope of your project—the breadth and number of experiments you will perform—and how this will achieve your goal(s). Furthermore, be specific—knowing exactly what you want to achieve will keep you motivated until you get there.Project managers often use the concept of the triple constraint to manage work: scope, time and cost are intricately linked in a project and the different level of focus that each is given affects the perceived quality (by others) of project deliverables (Fig 1). Project managers understand that any deviation in one of the triple constraints changes one or both of the others. This is where the project schedule really comes into its own by allowing you to forecast when you will complete the agreed goals of your PhD project. For example, is your doctoral programme for a fixed-term period? If so, then once a project schedule has been agreed that uses all of the time available, any project overruns will cause an overrun to the overall PhD. The two main possibilities for a PhD student to manage this situation and bring the projected completion back into acceptable timescales are either to work longer or to reduce the scope or goals of the project, either by conducting fewer experiments to answer the same question or by modifying the depth of the question being asked. This leads to the issue of whether there is a minimum set of goals that need to be achieved, or whether several agreed activities are ‘nice to haves'', but are not crucial for the overall PhD. I believe that your supervisor(s) are best suited to answer questions about the minimum goals and the scope needed to achieve them.Open in a separate windowFigure 1The project management triangle as applied to a PhD. Three competing constraints influence project management: time, scope and cost. The time constraint reinforces that projects are temporary endeavours, and that in most cases have defined timescales (absolute deadlines). The cost constraint refers to the budgeted amount allocated to the project that, from the perspective of doctoral research students, will predominantly be focused on the amount and duration of the stipend awarded, but might also incorporate various expenses such as bench fees, conference fees and consumables. For those changing career, the cost might also comprise an element of salary sacrifice. The scope constraint refers to what must be done, produced or developed to meet the objective of the project, which in the case of a PhD generally comprises the actual doctoral research to be performed, development (and submission) of the thesis, publication of one or more journal articles, presentation at conferences and potentially teaching. The triple constraint principle highlights that any change to one of the constraints will have an impact on one or both of the other constraints. For example, increased scope typically leads to increased time and cost; tight time constraints usually mean that an overrun in activities (such as experimentation) might have a knock-on effect of requiring the scope to be reduced to submit your thesis on time, or increasing the overall amount of time required to complete your PhD. Similarly, a tight budget could mean you cannot gain access to various resources, resulting in either increased time or a reduction in scope. Recently, a fourth component of the project management triangle has been introduced highlighting that along with the three constraints competing with each other, they also interact to form a fourth dimension of quality.If you need to complete your doctoral programme within a specified time frame, then you need to manage your goals and scope mercilessly—do not allow additional research questions or extra experiments to take away precious time. This does not mean that you cannot deviate, but any deviations need to be managed. Remember, whether you wish to remain in scientific research or not, the PhD is a stepping-stone to your future career and not the end goal in itself. Once you have achieved the goals agreed with your supervisor, it is more beneficial for you to write-up your doctoral thesis and move on [2].Good communication is essential in every area of work, but even more so for a PhD as you are simultaneously learning how to research along with doing the research. Often, access to your supervisor is limited by constraints on his/her or your time, which means that clear communication is vital. Do not assume that your supervisor knows every intricate detail of what you are doing; he or she might have a large group in which each member is looking at complementary aspects of a more general topic. It is, therefore, your responsibility to ensure that all your stakeholders—supervisors, postdoc leads and any others involved—know what you are doing and, more importantly, why you are doing it.This is another area in which the apt use of technology can maximize efficiency. Subject to institutional licensing, collaboration tools such as SkillsForge or Evernote can improve communication between stakeholders. For example, meeting minutes, action points to be followed and research results can be uploaded for sharing. Supervisors can then review the material at a convenient time to ensure that they stay up to date with the progress of each student within their research group.As PhD students usually aspire to become research scientists, it is of paramount importance that you learn the correct application of the scientific method and the context in which your work is being done. Before jumping into practical work—wet-lab experiments or computational modelling—it is important to understand the meaning and relevance of your project in relation to existing knowledge and the underlying science. For example, the hypothesis-driven research life cycle in systems biology [3,4]—my own field—advises that computational models should be developed on the basis of wet-lab data relating to the underlying biological system. Almeida-Souza and Baets state that a PhD in science is an opportunity to learn how to tackle problems scientifically and, as such, requires the development of skills in critical thinking, hypothesis formulation and experimental design [5]. I believe that the requirement for these skills is universal across the sciences, and that molecular biosciences and computational systems biology are no different.The serious consideration of scope is necessary in any project, but even more when you are simultaneously project manager, research scientist and key stakeholderTherefore, before the first wet-lab experiment is performed, or the first line of code is written, it is essential that we understand why the experiment is important and what results we might expect to support our initial hypotheses. Furthermore, regarding computational systems biology, I believe that it is also essential for wet-lab and computational researchers to collaborate to ensure both have a consistent understanding of the data and the purpose of the computational model. After all, for the most part, computational models are developed for their predictive capacities and to allow hypothesis generation for subsequent wet-lab experimentation. Baxter et al have extensively covered this area and advocate not only designing the project up-front, but also the need for quality control [6].You need to manage the scope and goals of your PhD mercilessly and, at the same time, be flexible enough to grasp new opportunities. Conversations at conferences, for instance, can open up opportunities for collaboration and take your research in a direction that you had not considered previously. In my case, I was invited to turn a conference paper relating to my masters degree into a full paper for a special issue of a well-known bioinformatics journal. Although it was not related to my doctoral research, the prospect was too good to turn down. I therefore discussed the idea with my PhD supervisor, and once we were in agreement, I updated the project schedule to incorporate this new activity, trying to mitigate as much as possible the resulting slippages to my doctoral research. In essence, I had performed an impromptu risk–reward analysis and decided that the reward that would be gained from publishing this work outweighed the risk of a slight overrun of my PhD thesis. It must be noted that I was lucky in this instance, as my PhD supervisor also supervised the research project during my master''s degree, so a full paper would be beneficial for both of us.A project risk is “an uncertain event or condition, that if it occurs, has an effect on at least one project objective” [1]. The positive side to risks is that the likelihood of their future occurrence can be mitigated by planning in the present. Once a risk is realized, however, and its effects begin to be felt, it has turned into a project issue. The first step in trying to manage risks is their identification. Risk identification in this context is the process of determining which events, if they occurred, would affect your research. In the context of a molecular biosciences PhD, I believe that general risks relate to access to resources, such as people—postdocs and collaborators, for example—reagents, cell lines and shared equipment. For example, if your work uses fluorescent proteins within single cell analysis, how would you be affected if the fluorescence microscope was booked out by another research lab? Similarly, in computational systems biology, if the design process for your computational model requires access to wet-lab data, what would the effect(s) be if this was not available?Once risks are identified, it is important to develop risk response plans. By using the above example of access to a microscope, what should your response be if you cannot gain access? The initial risk response would be to liaise with the other research lab to understand their requirements and ascertain whether you could gain access at a mutually convenient time. Alternatively, another approach might be to work outside normal office hours, either throughout the evenings or on the weekend, subject to health and safety procedures at your institution and your own health and well-being. I believe that a degree of creativity is often required when developing effective risk response plans.A PhD thesis is a hefty document that might run to many hundreds of pages. They are generally not written as a single large document from start to finish, but as chapters. In the molecular biosciences, a thesis consists of an initial literature review early in the doctoral programme, work-in-progress documents for materials and methods, experimental results throughout the middle section, which is followed by analysis and critical evaluation towards the end of your experimental work. Whether through software tools or through your own manual methods, such as keeping a configuration log and keeping a copy of each version of your working documents, it is essential that you maintain an up-to-date repository of all your notes. I have found through experience that it is beneficial to save not only the final versions, but also each of the working drafts of documents generated throughout your PhD. Ideas previously discounted, and thus removed from more recent versions of documents, might once again take centre stage at a later date.The positive side to risks is that the likelihood of their future occurrence can be mitigated by planning in the presentThis can be aided through the development and use of a project library with a logical folder structure to facilitate easy access to documentation. Noble [7] provides an in-depth discussion of organizing your computational biology project—in particular the value of version control—but the concepts are transferable across disciplines. Furthermore, do not forget to back-up your work, and without seeming too pessimistic, back-up your back-up!Finally, look after the most important resource: you. Exercise, diet, alcohol, caffeine and holidays all affect your well-being. Holidays and time away from the lab or office allow you to take a step back from the detail and reflect on your experiences and progress. Sometimes, time off allows you to process issues subconsciously and develop new approaches to overcome problems that you have been tackling for extended periods of time without success. Finally, holidays also help you recharge your batteries and enthusiasm to return to your project with fresh vigour. If you have sensibly and reasonably planned time off alongside your work, you will be able to enjoy it.Although a PhD requires consistent commitment, you simply cannot—and should not—work at full capacity all of the time. Issues arise periodically throughout any project, and if you have no reserves of energy—either mental or physical—you will be unable to tackle them head on with the step change of performance that is required. Furthermore, doctoral research is a marathon and not a sprint; we all experience the symptoms of burnout from time to time, and sometimes it is better to walk away for a short period to recharge than to carry on, become stale, and ultimately slow down.To conclude, I wish you good luck with your doctoral research, and I hope these techniques help you to manage your PhD project through to successful completion.?

Few medical faculty members are adequately prepared for their instructional responsibilities. Our educational traditions were established before we had research-based understandings of the teaching-learning process and before brain research began informing our understandings of how humans achieve lasting learning. Yet, there are several advantages you may have. If your expertise is at one of the frontiers of human biology, your teaching can be inherently fascinating to aspiring health professionals. If your work has implications for human health, you have another potential basis for engaging future clinicians. And, thanks to Claude Bernard's influence, you likely are "process oriented," a necessary mindset for being an effective teacher. There are also challenges you may face. Your medical students will mostly become clinicians. Unless you can help them see connections between your offerings and their future work, you may not capture and sustain their interest. To be effective, teachers, like clinicians, need to be interactive, make on-the-spot decisions, and be "emotional literate." If you aren't comfortable with these demands, you may have work to do toward becoming a truly helpful teacher. Program changes may be needed. Might your program need to change 1) from being adversarial and controlling to being supportive and trust based or 2) from mainly dispensing information to mainly asking and inviting questions? In conclusion, making changes toward becoming a truly helpful teacher can bring benefits to your students while increasing your sense of satisfaction and fulfillment as a teacher. If you choose to change, be gentle with yourself, as you should be when expecting your students to make important changes. 相似文献

Have you ever wondered why it takes so long to get comments back from reviewers at some journals? After all, how long should it take to review a paper? I suspect most of us have asked this question at one time or another. While recently contemplating this question I thought it was time to tell you a little about how we run Autophagy, and at the same time compare it to the practices at some other journals where I have, on occasion (notably before the start of Autophagy), sent my own papers. 相似文献

Growing demand has led some Canadian hospitals to offer alternative therapies to patients, even though many physicians still question their efficacy. Anita Elash visited Toronto''s Sunnybrook Health Science Centre, where staff physicians have been debating the issue. One physician said hospitals have no choice but to offer the treatments. "If you believe in the primacy of patients making their own decisions and you believe in the fundamental of informed consent, you cannot deny them access to this treatment." 相似文献

Prompted by the occasion of International Women''s Day, Joan Heath and DMM reunited Professors Suzanne Cory and Joan Steitz via Zoom to discuss their extraordinary careers and joint experiences in science. They also delve into past and present challenges for women in science, and discuss the role of scientists in a post-pandemic world. Suzanne Cory, Joan Steitz and Joan Heath (from left to right) As one of Australia''s most eminent molecular biologists, with a school in Melbourne bearing her name, Professor Suzanne Cory has been both Director of The Walter and Eliza Hall Institute of Medical Research in Australia (WEHI) and President of the Australian Academy of Science. She earned her PhD at the Medical Research Council (MRC) Laboratory of Molecular Biology (LMB) in Cambridge, UK, with postdoctoral training at the University of Geneva. She continues her research at WEHI as an honorary distinguished research fellow, investigating the genetics of the immune system in the development of blood cancers and the effects of chemotherapeutic drugs on cancer cells.Joan Steitz – currently Sterling Professor of Molecular Biophysics and Biochemistry at Yale University, and for 35 years the recipient of a Howard Hughes fellowship – is best known for her seminal work in RNA biology. She was the first female graduate student to join the laboratory of James Watson at Harvard University and proceeded with her postdoctoral training at the MRC LMB in Cambridge. Her pioneering research delved into the fundamental mechanisms of ribosome and messenger RNA interactions, as well as RNA splicing, heralding the phenomenon of alternative RNA splicing. A recipient of many awards and honours, she is also involved in international projects aimed at supporting women in science.Host Joan Heath heads a laboratory at WEHI in Australia. She received her undergraduate degree from the University of Cambridge, followed by her PhD at the Strangeways Research Laboratory also in Cambridge, then just across the road from the MRC LMB. After postdoctoral positions in bone biology and osteoporosis research, Joan joined the Ludwig Institute for Cancer Research where she became a laboratory head, and changed her focus to cancer research using zebrafish to identify genes that are indispensable for the rapid growth and proliferation of cells during development. She joined the WEHI in 2012. There she showed that the same developmental genes are also required by highly proliferative, difficult-to-treat cancers, including lung, liver and stomach cancer, paving the way for translational research targeting these genes in novel cancer therapies. Joan H: How long have you two known each other? Suzanne: I was calculating that this morning and I was astonished because it seems like only yesterday, but it has been 55 years since we met in Cambridge. It has been a voyage in science and a voyage in the world because we have always made a point to meet up in beautiful places and go hiking. That is how we''ve been able to renew our friendship over all these years. Joan H: Where were you when you first met? Joan S: We both were working at the MRC LMB in Cambridge, England. Suzanne was doing her PhD and I arrived slightly later for a postdoc.Suzanne: We had a pre-meeting in the sense that Joan, Jerry Adams (my future husband) and Tom Steitz (Joan''s husband), were all graduate students together in Harvard. So, when Joan and Tom came to Cambridge, it was natural that we would all start doing things together. And Joan and I ended up sharing a lab bench.Joan S: The reason that I did a postdoc in the mecca of X-ray crystallography was that I had married a crystallographer – and there was no other place that he could possibly go. They very much wanted to have my husband at the Cambridge MRC lab, but there wasn''t a clear plan for me. Francis Crick suggested that I do a literature project in the library, but I knew that theory was not my forte in comparison to experiments. I started talking to the many people working in the lab and found a project that no one wanted, because it was so challenging. But it was a very interesting problem, so I decided to take it on – and it turned out to be a great project.Joan H: That''s amazing. You were obviously determined to overturn other people''s expectations of you.Suzanne, even now, it''s extremely unusual for a young person to leave their home country to do their PhD. It''s still a brave thing to do but all those years ago it was really courageous. You told me that you ended up there because you wrote a simple letter, which was a complete shot in the dark.Suzanne: It certainly was. During my master''s degree at the University of Melbourne, I became more and more interested in doing science and decided I would do a PhD. But I had a counteracting desire to travel and see Europe. So I decided that I would do my PhD overseas to give myself the opportunity of travelling. I had fallen in love with DNA during my undergraduate studies. So, I wrote a letter to Francis Crick in Cambridge, and asked if he would take me on as a PhD student. Much to my amazement, I eventually got a letter back saying yes. I think that my professor of biochemistry might have also visited Cambridge while he was travelling and spoken up for me. However, I was still extraordinarily fortunate that Francis had agreed because there weren''t many PhD students in the LMB at that time. It made such a difference to my entire life. I look back on that letter and think, “How did you have the audacity to write that letter and aim to go to that laboratory?”. I think it was partly naivety.Joan H: That''s a lesson for everyone, to go for your dreams, and don''t assume people won''t take notice of you. It is more difficult now, when scientists receive hundreds of e-mail applications from prospective PhD students in their inbox. You would have written a letter with a stamp on it that probably took three weeks to arrive, but it just shows you that you should be audacious. Did you have a different experience to Joan when you arrived? Was there a proper project already lined up for you?Suzanne: I was interviewed by Francis Crick and Sydney Brenner, who were the joint directors of the department. They decided that I would work on the structure of the methionyl-tRNA that puts methionine into internal positions in polypeptides. After they described the project – which involved doing counter-current distribution fractionation of bulk tRNAs, in which I had no experience whatsoever – Sydney in his very characteristic monotone said, “Do you think you''re up to it?”. I sort of gulped to myself and said, “Yes, I think I could do that”. I then went to Brian Clark''s laboratory, who was going to be my PhD supervisor, and started the project. Like always in life, if you learn from people and just go from one day to the next, you actually get there in the end.Joan H: So, persistence was key. Were there many other women at the LMB at the time?Suzanne: I don''t remember any female scientists who had official senior positions. There were certainly some strong female scientists there, but I don''t think they were given the recognition or the status that they actually deserved.Joan S: Later, some were given more recognition, crystallographers in particular, but not so much the molecular biologists.Suzanne: I think, as women, we both pioneered in that department.Joan H: Given the fact that you both agreed to take on projects you had very little previous experience with and that the male supervisors thought you weren''t going to have the mettle to carry it through, once you were there, did you feel that you had to work the whole time? Or did you still manage to have lots of fun and partake in opportunities that Cambridge had to offer at the time?Joan S: We certainly partook in a lot of those things. My husband and I got interested in antique furniture, antique paintings, and used to scour the countryside for little antique shops. We saw lots of England, then a little bit of Scotland and Wales. It was wonderful. A real adventure.Suzanne: I worked really hard most of the time that I was in Cambridge, as the work was very exciting. But I would take holiday periods, camping and youth hostelling all over Europe with a girlfriend from Melbourne and later, travelling with Jerry. We also would go to London for the opera and looking for amazing clothes on Carnaby Street and Chelsea Road (this was the Beatles era, late 60s). Jerry once came back with a purple velvet suit, which was his prized possession for many years. There was lots of fun but also lots of work.Open in a separate windowJoan Steitz, Tom Steitz, Jerry Adams and Suzanne Cory (from left to right) in the Swiss Alps, 1970.

Joan H: Can you remember the first moment in that part of your career that gave you the most pleasure? Joan S: I worked on a project for about a year, and it turned out that I was doing the wrong fractionation method to get the material that I needed to analyse. Then I had a conversation with Sydney Brenner telling him that I was going to give this one more try with a new method, and then I was going to give up. I remember Sydney saying, “Sometimes, like with a bad marriage, you have to give experiments one last try before you give them up.” Then I tried again, and it worked. This is often the case in science, that you try something new, that''s a little bit different, and it makes all the difference. Then you''re running.Suzanne: The same thing happened to me. I was labouring away on the counter current distribution machines fractionating methionine tRNA, with the goal of sequencing it by the laborious procedure recently published by Robert Holley. However, Fred Sanger, in the department upstairs, had invented a totally new method for sequencing using 32P-labelled RNA. I desperately wanted to try this, so I managed to persuade my supervisor that we should change techniques. That change was key to my future because the approach was successful. I still remember to this day exactly where I was in Cambridge, walking on a Sunday afternoon, when the last piece of the puzzle dropped into place in my mind, and I had the entire sequence. In that moment, I was extremely joyful, because I knew I had my PhD and that I had succeeded. So that was my eureka moment.Joan H: Obviously, these were extremely productive years, and you''ve mentioned several Nobel Prize winners in your midst. It must have been the most inspiring environment, which I''m sure had a big impact on what you did next. By this stage in your career, were you already feeling ambitious or was it still your scientific curiosity that was driving your path?
“I expected that I would go back to the United States and be a research associate in some man''s lab […]. Then it turned out that people were more impressed than I thought and started offering me junior faculty jobs.”Joan S: I had gotten a lot of recognition for having sequenced a piece of mRNA, using the same methods that Suzanne used to sequence tRNA. However, I had no expectations, because I had never seen a woman as a science professor, or head of a lab. I expected that I would go back to the United States and be a research associate in some man''s lab, and maybe they''d let me guide a graduate student. Then it turned out that people were more impressed than I thought and started offering me junior faculty jobs.My husband had already secured a junior faculty job in Berkeley before we even went to England, so we went back there after two years. My husband went to the chair of the department in Berkeley and put down letters on his desk of job offers that both of us had received for independent, junior faculty positions from several universities. The Chairman then said to Tom, “But all of our wives are research associates in our labs, and they love it”. This tore at my pride, as there had been a couple of universities that offered us both faculty jobs, and Berkeley was only offering one. So, we didn''t stay at Berkeley, and we came to Yale, which was wonderful.Suzanne: It''s really amazing to think that they gave you up. How foolish they were.Joan H: They''ve lived to regret it a million times over. Suzanne, at that point were you ready to climb this very difficult ladder?Suzanne: Like Joan, I didn''t have any expectations. For me, it was a matter of being able to continue discovering things in science. Jerry had already arranged to start a postdoc in Geneva. So, I applied for a postdoctoral fellowship, and obtained one. We went off together to Geneva to start our married life, and that was the beginning of us doing science together, which we''ve done ever since. I think without Jerry guiding me at that stage in my life, I would have probably drifted out of science. I don''t think I had the scientific confidence to ever think that I would be running a lab. For me, it was just continuing a voyage of discovery; and being lucky to end up in a wonderful scientific partnership and, through that partnership, my confidence grew over the years. Joan H: How many years after your postdoctoral training was it before you looked around your environment and had the confidence to think that you could be a lab or department head or could run an Institute? Joan S: I would say that confidence just grew. Tom and I were part of a departmental overhaul that involved hiring about six new people at Yale. We all stuck together, supported each other and were very collegial even though we worked in different areas. I think the collegial nature of the department in Yale helped me gain confidence. It was very scary at first because I didn''t know if I could write grants or direct people.Suzanne: Cambridge had an incredible influence, certainly over me, and I''m sure over Joan, Tom and Jerry, too. We looked around and saw all these amazing Nobel laureates, but also all these very ambitious, talented postdocs from around the world. I don''t think anyone thought about being the head of a department at that stage. We were simply striving to make discoveries and we gave each other mutual confidence, and stiff competition, too.The other thing that Cambridge gave us, was a new technology. For Joan and me, it was RNA sequencing. Being able to do that technology opened doors all around the world. I now always advise young people to go to the best place in the world to train in your chosen subject and acquire a new technology, because that will open the door to many opportunities in the future.Jerry and I made some excellent discoveries in Geneva, which were published in front-rank journals. Then it was time to move to full independence. I really wanted to go back to Australia but, as Jerry is an American, it was not at all obvious that he should take the big leap of moving to the bottom of the world and starting a lab there. I owe him a tremendous debt because he decided that he would take that risk.Earlier, whilst on our honeymoon, we had visited various labs in Australia. Although WEHI was an institute for immunology, a field we knew little about at that stage, it had the same atmosphere as the LMB in the sense that everyone was striving at the frontiers of science and competing with the rest of the world. We decided this was the only place in Australia that we would work at and that we would attempt to persuade the new director Gus Nossal that he needed molecular biologists. We had an interview with him in Switzerland and he offered us jobs as postdocs. Again, we were probably very naive and audacious but we told him we didn''t want to be postdocs – we wanted to run our own lab. And he agreed and we launched our fledgling lab together in 1971. What drove us was always discovery, rather than career ambitions.Joan H: You''ve both described these amazing sets of circumstances that were challenging but, nevertheless, very satisfying. However, a lot of things have since changed. What do you think are the main remaining barriers to women in science?Joan S: There is an important phenomenon called social identity threat, or stereotype threat, that I think still impedes women in proceeding in their careers. The phenomenon is described by cognitive psychologists as a reaction that all people experience if they feel that they are part of an undervalued minority. And so, by definition, since there are fewer women in science than there are men, women are being subjected to stereotype threat. Cognitive psychologists have studied the physiological manifestations of this, including increased heart rate and perspiration but, psychologically, they''ve also documented that cognitive learning and memory are impaired when one has these feelings.I first learned about this in 2007 and I looked back and realized why, for 30 years, when I''d been on committees as the only woman amongst ten men, I wouldn''t dare say anything – because I was frightened stiff. Men undergo this response, too, if they''re put into the situation of being undervalued. If you understand why you''re reacting the way you''re reacting and know that this is a normal human response, I think it helps you to overcome your own feelings of insecurity and allows you to go ahead. I always tell young women who I''m rooting for in science about this, because I want them to know that they will very likely end up feeling this way, and it''s a normal human response.
“One thing I sometimes get frustrated about is that we often need men to change things […] but what we really need are women in those high-level positions, so that they can be the champions of change.”Joan H: There are other terms describing other relevant phenomena, such as unconscious bias, imposter syndrome and champions of change. One thing I really relate to is imposter syndrome. I''ve listened to webinars on this topic and they all reach a similar conclusion that we all feel the same. On the one hand, at the end of the webinar, you do feel somewhat elated to know that it''s not just you, and that it''s normal. But, on the other hand, it doesn''t really change things. It''s a recognition of what we feel, and we all get some help from that, but you really need opportunities to change things at a higher level. One thing I sometimes get frustrated about is that we often need men to change things, leading to this concept of male champions of change. I admire those men; but what we really need are women in those high-level positions, so that they can be the champions of change. Not having 50% of university departments and medical research institutes run by women still limits our full potential.Joan S: I certainly agree with you, Joan. It''s very important to have realistic role models. Suzanne being head of the WEHI for all those years has engendered all sorts of admiration.Joan H: During that period, Suzanne not only did fantastic science but our Institute doubled in size.It''s transformative when you have women making up 50% of people around the table. It''s no help just having a token female because that poor person''s not going to be able to change everything on her own. In American scientific institutions, are there any firm quotas for female scientists and other people that are underrepresented in science?Joan S: In recent years there has been a push in that direction. Sometimes it''s successful and sometimes it''s not. It is very different now compared to when there was no consciousness that this was unfair or that things could be better if we had real representation.Suzanne: I agree with both of you in everything that''s been said. While reflecting at this moment, what it says to me is that what''s really needed is societal change, and that we need to give courage to girls from the very earliest age. It should come naturally, they shouldn''t feel inferior, and others should not look at them as inferior. They should expect to have careers as well as families, be able to manage both and have somebody alongside them who helps them manage both.I think that affirmative action for women in science is necessary because the pace of change has been so slow. However, I also think quotas can be detrimental to the cause of women, in the sense that it''s then possible for people to say you only made it because there was a quota – which is very destructive. If I look back on our careers in science, it is clear that things have changed tremendously. Today there are more opportunities for women because many universities and institutes are bending over backwards to equalise things. The downside of this is that talented men may miss out on positions because of this policy and the pendulum could swing back.Joan H: The evidence shows that when more women are involved in things, those things go better. For instance, boards that have more women on them are more productive. Obviously, what you alluded to is there are lots of fantastic male scientists as well. The real issue here is there''s not enough funding to go round to support all the great men and women. But there are clearly enough good women around to be represented at the 50% level, without disproportionately disadvantaging male scientists.Joan S: Men and women are now operating on a more even playing field, which doesn''t mean that the men are missing out. They''re just in a more-competitive situation – as they should be. Joan H: Suzanne previously covered the specific advice she would give to young female researchers. Joan, do you have any other suggestions? Joan S: I encourage them to try lots of different things in science, and when they find something that really grabs them, then go for it and be persistent. We all know that science is very up and down. But if you keep pushing when you''re in a trough, it will always go back up again and you will succeed. That''s harder for a young person, who hasn''t experienced these troughs, to understand.Joan H: Yes, and the period when women scientists start having children is the hardest part. It''s still a choice that some women make, to take some years off and come back with a less ambitious plan for their career. Obviously, things like maternity leave payments and so on are improving but there''s no question that, in most circumstances, the research will slow down during that period.Suzanne: What I say to young women at that stage of their careers is that you have to be very focused, you must spend the time that you do have in a very focused manner, so that you can be the most productive you can be. But you have to be supported at home by your partner. If you''re both scientists it''s easier because you can appreciate why the other person is rushing into the lab late at night, for example, but for most people, that''s not true. So, what is really important is equal sharing of responsibilities from both partners when young families are around. And I think employers need to give both of those partners a longer time to achieve the kind of papers that they need to progress in their careers. That''s a period when it is much harder to be productive, and we need to continue to support people during that difficult phase of their careers because we''ve invested so much in them. They have so much to offer to science and to society, so to let them slip out at that stage is a great waste.Joan H: Let''s change tack a little bit and think about some of the broader challenges in science. What do you think the COVID-19 pandemic has taught us about the importance of clear scientific communication and real engagement with the community?Joan S: Whenever I talk to people about this, I very clearly make the point that it was decades of fundamental research that led to the development of the COVID-19 vaccine. If it hadn''t been for those fundamental discoveries in how cells and mRNA work, it would never have only taken 63 days from sequencing the virus to phase one clinical trials at Moderna. I try to point out to people that all the different discoveries coming in from different angles made that possible. I personally find it absolutely remarkable that all that knowledge could be harnessed, so very quickly. I''ve been doing fundamental research my entire life and I never expected to see it materialise in the way it has. It''s a wonderful reward. Joan H: Do you think this has resulted in the community appreciating scientists more? Joan S: I don''t think we''re far enough downstream to know that. In the US, there has been a congressional vote to abandon our maintenance of vigilance and preparedness for future pandemics – which seems ridiculous. Now we have all these procedures set up, all we have to do is maintain them for the next one. Whereas, if we just let go of these procedures, we''ll have to start over again for future pandemics. I guess we''re not good enough at communicating some of these things at this point.Joan H: Millions of people died from the virus and yet, if we hadn''t had the vaccines, the scale would have been even more horrific. If we were able to convey this information effectively to the public, then, hopefully, people would recognise that – as well as spending a fixed percentage of the gross domestic product on defence, for example – we should spend at least the same amount on science. Not only for pandemics but for tackling climate change and other pressing issues. I like to think this is an auspicious time but I don''t know whether we are really taking advantage of it.Suzanne: The pandemic has brought science and scientists to the forefront, and there has been a period of great respect for scientists having developed the vaccine. It''s an absolute miracle that it was done so fast and effectively. We''re very fortunate but, as Joan said, that was not luck. It was through investment in basic science for decades. We have to keep conveying this message, to our politicians in particular, so that they will keep supporting all kinds of scientists, because we never know what''s around the corner.Joan H: Certainly, people like Anthony Fauci in the US and Catherine Bennett in Melbourne, spoke eloquently and had a real talent for communicating things clearly and in a nutshell. That''s not something we''re all good at and it''s not something that is easy to train into people either. I think we all need to try to capture the attention of the community at large, by speaking plainly. I don''t think people understand that scientists are underfunded and could do so much more if funding was more generous.
“All I can say to young people is, if you really love science and have a passion for it, keep trying – because you will succeed if you put your whole heart and soul into this career path.”Suzanne: I think the general public has no appreciation of how tenuous the life of a scientist can be, and how we are losing so many great minds entering the field because young people just finishing their PhDs look with dismay at how hard it is to support a career in science and get enough funding. There''s a tremendous waste of talent. All I can say to young people is, if you really love science and have a passion for it, keep trying – because you will succeed if you put your whole heart and soul into this career path.Joan H: This has been an absolutely fantastic discussion and it''s such a delight to talk to women who, after all these years, are still as passionate as ever and are pursuing their scientific subjects with the same vigour as they have all along.Suzanne: It''s been wonderful to talk with you, Joan, and I hope that we see each other soon, no matter what continent. And thank you, Joan Heath for getting us together and giving us this opportunity. 相似文献

R is an increasingly preferred software environment for data analytics and statistical computing among scientists and practitioners. Packages markedly extend R’s utility and ameliorate inefficient solutions to data science problems. We outline 10 simple rules for finding relevant packages and determining which package is best for your desired use. We begin in Rule 1 with tips on how to consider your purpose, which will guide your search to follow, where, in Rule 2, you’ll learn best practices for finding and collecting options. Rules 3 and 4 will help you navigate packages’ profiles and explore the extent of their online resources, so that you can be confident in the quality of the package you choose and assured that you’ll be able to access support. In Rules 5 and 6, you’ll become familiar with how the R Community evaluates packages and learn how to assess the popularity and utility of packages for yourself. Rules 7 and 8 will teach you how to investigate and track package development processes, so you can further evaluate their merit. We end in Rules 9 and 10 with more hands-on approaches, which involve digging into package code. 相似文献

To tell the truth, I find it difficult to work when flying, or even when sitting in an airport for an extended period of time. So, typically I take along a book to read. And when I truly cannot concentrate, for example when a flight is considerably delayed, I have even been known to resort to word puzzles. Depending on the type, they do not require much attention (that is, you can pick up right where you left off after you glance at the flight status screen for the twentieth or so time, even though you know nothing has changed), or effort (although you need to use a pen or pencil, not a keyboard), but nonetheless they can keep your mind somewhat occupied. I even rationalize doing them based on the assumption that they are sharpening my observational/pattern-finding skills. One type of word puzzle that is particularly mindless, but for that very reason I still enjoy in the above circumstances, is a word search; you are given a grid with letters and/or numbers, and a list of “hidden” terms, and you circle them within the grid, crossing them off the list as you go along. I do admit that the categories of terms used in the typical word searches can become rather mundane (breeds of dog, types of food, words that are followed by “stone,” words associated with a famous movie star, words from a particular television show, etc.). Therefore, on one of my last seminar trips I decided to generate my own word search, using the category of autophagy. 相似文献

Mr. Chairman. Distinguished ladies and gentlemen. As Dean of Science it is a great honour on behalf of the University of Copenhagen and the Faculty of Science to welcome all of you here to the 8th International Symposium on Tardigrada. We are especially happy to have you here at the August Krogh Institute (named after our well-known Nobel Prize winner in Physiology), because on September 1st we celebrate the establishment of the Faculty. So coming here and honouring our 150 year anniversary jubilee help us to promote the importance of science in our society. The University was founded in 1479 as a theological catholic school. It broke down in 1530 and was reestablished in 1537 after the reformation. Right from the start in 1479 there was science thought of at the university. Mathematics and Astronomy. And Zoology became a subject over the centuries together with other subjects which are today regarded as science. But only in 1850 did we become an independent Faculty thanks to the effort and progress done by the Danish Chemist H.C. Ørsted.The animals, which you study, are marvellous in the sense that they can survive under severe conditions for centuries. Under extreme dry conditions in Sahara, in extreme cold conditions (they can survive minus 273 °C, or survive in vacuum). This has practical implications for people who need to excuse their scientific interest, for medicine if we can freeze human tissue, or for space study how to survive under extreme conditions. The study of Tardigrada is an important field here at the Institute of Zoology, at the Zoological Museum, and at the University of Roskilde, 30 km west of Copenhagen. Some of our most distinguished zoologists take part in this research. That might be the reason why you have chosen to have the symposium here in Copenhagen. They are doing research on tardigrades in marine areas, and in Greenland on the ice cap. Especially interesting are the studies done in the Ikka Fjord in Greenland, where the unique Ikkaite Tufa columns made of calcium carbonate hexahydrate originating from alkaline cold springs at the bottom of the fjord create very specific environments with nearly brackish conditions in the center and sea water salinity on the outside. And this creates varied conditions for different species of Tardigrada.We also celebrate this year the 50th anniversary of the 2. Galathea expedition which went round the world and specifically looked for deep sea fauna. There are Tardigrades here. It has been interesting to look through the 54 abstracts in the programme and read the names and work places for the 65 participants listed. In English tardigrades are called water bears, in Danish “bjørnedyr” meaning bear animals. I prefer the Danish version, this sounds more like pet bears.The symposium is followed by a field trip to the faculty's research station on Disko in Greenland. In 1994 I arrived on the new research vessel “Porsild” to Disko to deliver the new boat some of you will sail in during the workshop up there. I stayed there some days, and there was this man Professor Reinhardt Møbjerg Kristensen, looking into his microscope. It was fascinating to see the joy which he expressed explaining his animals. His engagement was so impressive and his talk so marvellous. It was really his pet animals he caressed all day and night. If all of you are looking on the water bears with the same fascination and engagement, then this will be one of the most entertaining symposiums ever held. One can fear that you are so engaged that you will forget everything around you, even to listen to the contributions of the others, and to be careful that maybe a new group will be announced.I wish you some very good days here at the Faculty of Science and some very fruitful days. I should like to thank the sponsors of the meeting, The Danish Science Foundation, The Carlsberg Foundation and Dr. Bøje Benzon Foundation. I would like to express my gratitude to the organizing committee for attracting the conference here and making the programme so wide and interesting. I can promise the committee will do all their best to help you all way through. And for those going to Disko — you will have a most splendid experience.I shall ask my colleagues at my own institute, Geography, to arrange some bad weather except on Thursday where you join the excursion. This to prevent you from sneaking away and enjoy the wonders of Copenhagen.By this once again welcome and a wish for a fruitfulconference. 相似文献

Science is a career where you do what you love everyday. Our science is built on the shoulders of those who came before us, and in turn we provide shoulders for our students and colleagues to build upon. Of course, seeing the seeds of ideas that we plant bear fruit as interesting science is why I love being a scientist. Looking back it also has been a particularly gratifying challenge to mentor members of the younger generation in building their careers. 相似文献

Nobody can do everything discussed in this article. Choose several ideas and try them. Increase your profile by letting more people in the hospital know who you are, what you do, when you do it, and how you do it. Get noticed and develop a reputation as the "go to" department. It will be worth the effort and increase your stature within the hospital. It may also help you get more staff and assume additional duties. Most of all, it will increase the respect of your department, and promote a more smoothly operating asset management system. 相似文献

If you draw from memory a picture of the front of your childhood home, you will have demonstrated recall. You could also recognize this house upon seeing it. Unlike recognition, recall demonstrates memory for things that are not present. Recall is necessary for planning and imagining, and it can increase the flexibility of navigation, social behavior, and other cognitive skills. Without recall, memory is more limited to recognition of the immediate environment. Amnesic patients are impaired on recall tests [1, 2], and recall performance often declines with aging [3]. Despite its importance, we know relatively little about nonhuman animals' ability to recall information; we lack suitable recall tests for them and depend instead on recognition tests to measure nonhuman memory. Here we report that rhesus monkeys can recall simple shapes from memory and reproduce them on a touchscreen. As in humans [4, 5], monkeys remembered less in recall than recognition tests, and their recall performance deteriorated more slowly. Transfer tests showed that monkeys used a flexible memory mechanism rather than memorizing specific actions for each shape. Observation of recall in Old World monkeys suggests that it has been adaptive for over 30 million years [6] and does not depend on language. 相似文献

Geoffrey W. Smith is currently the Managing Director of Mars Ventures. He actually started his studies with a Bachelor of Arts degree and a Doctorate in Law but then, in part by chance and in part by following in his family footsteps, he stepped into the healthcare and biotech field. Since then, he has successfully contributed to the birth of a number of healthcare companies and has also held academic positions at the Icahn School of Medicine at Mount Sinai and at The Rockefeller University in New York, teaching about the interface between science and business. During 2014 he served as Senior Editor on Disease Models & Mechanisms, bringing to the editorial team his valuable experience in drug development and discovery. In this interview, Geoff talks to Ross Cagan, Editor-in-Chief of Disease Models & Mechanisms, about how he developed his incredibly varied career, sharing his views about industry, academia and science publishing, and discussing how academia and industry can fruitfully meet to advance bioscience, train the scientists and stakeholders of the future, and drive the successful discovery of new therapeutics to treat human disease.Geoffrey W. Smith was born in 1965. He obtained a Bachelor of Arts degree from Williams College in Williamstown, MA. After a stint as a Research Associate at Harvard Business School, he graduated from the University of Pennsylvania Law School. Following a federal court clerkship and first job experiences in law, he joined a healthcare services start-up named Advanced Health as one of its first employees. Geoff then co-founded various healthcare and technology companies, including Interbind and Ascent Biomedical Ventures, and is still a Managing Partner at the latter. In 2012, he joined the Icahn School of Medicine at Mount Sinai, first as Professor in the Department of Population Health Science And Policy, and then as Director and co-founder of the Design, Technology, and Entrepreneurship PhD program. Until December 2014, he was a Senior Editor at Disease Models & Mechanisms. Geoff is now Managing Director of Mars Ventures.Let''s start with your background. You have a Bachelor of Arts degree and a law degree. How is it exactly that you ended up working in biotech and pharma?My career path has been anything other than linear. I was actually pursuing my legal career when two entrepreneurs turned up at the law firm I was working for with an idea for a new technology-based company focused on more effectively managing healthcare services. I was a new associate without much to do, so I got assigned to work with the start-up and after about a year they asked me to come and join the company, Advanced Health. I had grown up in a very medically oriented family – my father was a medical school professor, my older sister was a PhD, and my younger sister is a medical doctor – and so to a certain extent joining a start-up in the healthcare space was a bit like joining the family business.We had a fair amount of success with that company. A little less than 2 years after I joined it, we had a successful initial public offering, and that started me down the road of participating in the start-up environment around healthcare.It sounds like it was not a surprising path for you. Which key people influenced you?Actually, it is somewhat surprising in that I had really prepared for and expected a career in law. Certainly, the work I did in law school and the first jobs I had after that started me on a different career. I was really focused on international relations and international law. The twist was that I got brought back into the healthcare arena, and ultimately the biotech arena, by a serendipitous connection – one of the entrepreneurs who started Advanced Health had trained at Brigham Women''s Hospital where my father was the Chief of Cardiology. It was through this connection that I became more than just an associate drafting legal documents and really began to build a close relationship with the founders, which ultimately led to me joining that business. This taught me that you can spend much of your time preparing, and thinking that your schooling is going to take you in one direction, but individual relationships can change your path and take you somewhere else altogether. In my case, these particular relationships stemmed from my father, who clearly had an enormous influence on me. He was both a practising clinician and a basic researcher, studying basic biology related to the function of sodium and potassium in the heart, but he also did applied research. He helped develop a radioimmunoassay test to measure digitalis levels in the blood and ultimately was involved in developing a drug called Digibind, an antidote to digitalis toxicity, which was one of the first drugs to use antigen-binding fragments [Fab] as the basis for a drug. Watching him manage these different activities in his career had a big influence on me.
“This taught me that you can spend much of your time preparing, and thinking that your schooling is going to take you in one direction, but individual relationships can change your path and take you somewhere else altogether”I think that each of my sisters – as I said, one of whom went down a PhD route and one of whom went down a medical training route – had a big influence on me, as well. Watching the challenges that they had to face in those areas in some ways pushed me to go off towards law school and take a different path. It also brought me back to one of the aspects that I think is the most rewarding in the bioscience field, which is that you can have a profound impact on a large number of people through your efforts, whether they be purely research-based, academic-based or commercially-based.One of the things I was constantly impressed by is that you always seem to have a good feel for the health field and the biology field. Is this because it is something of a family business?I think so. Growing up at my dinner table, I was just privileged to get to meet and interact with a lot of incredibly successful clinicians and researchers. For me those were comfortable conversations: these were friends and so there was a comfort level being involved in that environment. I didn''t feel a lot of intimidation from it, which I think sometimes people who come from the outside do.One of the aspects I really like about the bioscience field is the impact of ideas. Success is really about one''s ideas and ability to execute them, and that was very appealing to me. It wasn''t about how much money you had or where you went to school, it was really about the ability to think deeply about a problem or a potential advancement and figure out a way to find a way forward. It is also a very people-driven process because it is not only about thinking deeply yourself but also about thinking deeply with those in your field or adjacent to your field. Lots of different personality types can succeed in this field, but I think it is certainly easier for people who have an affinity for sitting with people and thinking about a common area of interest.To that point, you actually have walked between business and scientists. What do you see is the difference? Some of the priorities are obvious, but what are the differences in terms of what motivates people in the two? Are the personalities that you come across different between the basic science world, the translating science world and the business world?I don''t think the personalities are particularly different. I think you find introverts and extroverts and everything in between in each of these areas. I am not sure that personality is necessarily a good predictor of success. I think it''s a question of what toolset you are most comfortable using to get at a problem, and where in the lifespan of a problem you''re interested in working.For example, scientists in academia very often are interested in working at an early stage of a problem. They understand something fairly basic about a process or something earlier in the understanding of a field. People who gravitate towards industry, instead, are more excited about working on the later part of a process, so, rather than trying to understand what the fundamental working mechanism is, they want to understand how to work that mechanism in a way that is predictable and repeatable.Obviously people in the commercial realm are often highly influenced by money, but even that I don''t think is really particularly the differentiator. There are plenty of academics who are driven by money as well. I really think it has much more to do with where on the spectrum of understanding one is interested in working. Industry is geared to solving practical problems and, if a lot is understood about a problem, to getting down to the ability to repeatedly and safely intervene, whereas academia really lends itself more towards understanding the front end of a problem or of an unknown mechanism to understand it first and at a more basic level.What about working in teams versus individually? Do you see a difference there?I think that has changed over time. I think it is very hard in academia today to be the brilliant solo investigator. I''m not saying it''s impossible but, considering the increasing size of the data sets one is working with, the statistical methods one has to use, the complexity of different fields overlapping with each other, it''s just very hard to handle all the necessary aspects of modern science as an individual. Increasingly, working in teams isn''t a choice: I think it''s a necessity in order to be effective. The difference may be that, in academia, often the teams are teams of collaborators (meaning they have influence but not necessarily power over all people participating in the team) who may work for different institutions, whereas, more commonly in industry, teams are working within a single corporate structure. In industry more often there are hierarchical relationships, which may allow for more directive behavior. Again, I''m not sure I would draw as much distinction between team or not team and between industry and academia, but I might draw somewhat of a distinction between how those teams function and how one manages a team. I think they are a bit different between the two realms.
“Increasingly, working in teams isn''t a choice: I think it''s a necessity in order to be effective”Let''s turn to Disease Models & Mechanisms [DMM], where you have been a Senior Editor. What did your experience at DMM teach you about science publishing that perhaps you hadn''t thought about, and has it made you think more deeply about what goes into a good scientific piece of work? What were some of the surprises?Watching the detailed process that is necessary to take a piece from an initial submission through to a published article gave me comfort and respect for the level of diligence and the level of attention that the reviewers brought to the vast majority of the pieces. It gave me a good feeling that the science community can be a strong self-reinforcing organization that takes its responsibility to heart and only publishes the best of the work available. I think that was very reassuring.An interesting question for me was: is there a different function that the publication process could play in helping to galvanize new ideas or new interactions among different fields? That seemed to be challenging because people don''t want to rush out there without their ideas and data being fully thought-out and fully vetted. But still, somewhere in my mind is this notion that there should be an option in the publishing world to play a little bit earlier in the generation of new ideas.Do you mean journals having an earlier relationship – earlier in the experimental process with a laboratory – to work with them to provide advice?I don''t know if it''s to provide advice. One of the things I was struck by at DMM is that there are these different siloed research communities – for example, the fly and the fish communities – in which interactions and relationships in the individual fields are so well established and routinized. And the outcome from a publishing standpoint is still the canonical academic paper that has been relatively unchanged over a long period of time. Yet, we have had these tremendous changes in information and communication technology such that the manner of knowledge production and the methods of communicating in other parts of society have changed dramatically. It feels like there hasn''t been nearly as big a concomitant communication change in the biomedical sciences, and so the silos and the standard paper remain the way things are done.The publication process, because of its preciseness, can take quite a long time, so the musing here is whether there is a way that the publishing industry could facilitate an earlier, more speculative communication of interesting results in a way that would positively impact the field by turning over new information sooner. If you look at an area like maths, for example, and their pre-print servers, there is more of a notion of putting ideas out in the community that acts as a kind of peer-review process and a way to get the community interacting on new ideas early. That doesn''t seem to get a lot of attention in the life sciences area. It seems to me that even journals like the PLOS journals that are pushing towards a more open world of communication are still ending up being pulled back into the canonical paper form to communicate.
“…the musing here is whether there is a way that the publishing industry could facilitate an earlier, more speculative communication of interesting results in a way that would positively impact the field by turning over new information sooner”I guess one of the issues on the biology side is that there is a real emphasis on trying to get your paper into the most prestigious journal, so people don''t want to drop that paper until it is as far along as possible to aim at high-impact journals.That of course becomes a self-reinforcing system. If the yardstick used in the life sciences industry is publication in high-impact-rated journals, then you are going to get that behavior. But if you''re interested in the generation of new knowledge and in moving your field forwards, it is at least plausible that publishing in a quicker fashion or with at least some outlet to move more creative ideas ahead would be attractive.There are clearly challenges to that. But I do think it''s remarkable that if you look at almost every other media area there has been a huge amount of change since the advent of the internet era, but there really has been very limited change around life sciences publishing. It''s been surprisingly conservative to me. I am wishing there would be more experimentation to find other ways to communicate information sooner and in a way that could spur more creativity.Of course, when you tie publishing back to industry, for competitive and intellectual property protection reasons, industry tends to not really want to get out in the front with its most interesting work too early. I think that a lot of things being published out of industry are not the most interesting stuff that is happening. But again it seems to me that another area that science publishing should be thinking about is how they could come up with other solutions that might provide for a more creative interaction between publishing and industry.Talking about old models versus new models, let''s move to issues of training. Another area that you''ve been impressive at is the training of scientists. You''ve had your hand in creating a new PhD track at Mount Sinai called Design, Technology, and Entrepreneurship [DTE]. What is your view about how we train scientists, what we''re doing better these days and what you would like to see being done better to train them?It seemed to me that there was a remarkably small amount of experimentation in academia around thinking about how to train biomedical PhDs, and that academia had missed the opportunity to provide a better set of tools to PhDs to allow them to be effective across a wider range of potential career outcomes. The majority of biomedical PhDs are not ending up in tenure-track faculty positions but rather in the ‘alternative career track’. It seemed to be disingenuous to train them solely for the academic track if in reality the majority were going to some other career track.So what I was really excited about in putting together the DTE program was trying new ways to train PhDs to be effective askers of questions and proposers of solutions, and to create an environment where they could gain experience in how to solve a variety of problems effectively.
“…what I was really excited about in putting together the DTE program was trying new ways to train PhDs to be effective askers of questions and proposers of solutions, and to create an environment where they could gain experience in how to solve a variety of problems effectively”This meant that our students had to be rigorously trained as scientists, but this was an ‘and’ opportunity and not an ‘or’ opportunity. In addition to being trained as excellent basics scientists, we wanted to give them some training in how engineers think about problems, how designers approach issues, what tools those people use and how that impacts how they try to solve a problem. Hopefully over time this would produce students that are better suited for interacting and influencing other parts of society – be it industry, government or policy – and better positioned to compete in what is a very competitive job market.What were some of the things you did in the DTE training to get at this?We really tried to teach theory in the context of real problems. Virtually all the classes of the DTE curriculum were problem-driven. We created a class that we called ‘The Q.E.D. Project’ that followed along from efforts at Stanford and elsewhere to teach students how to identify an unmet need. We then asked them to form a team to address the unmet need, and then helped them understand how to build a prototype to address that need. Along the way, we also talked about what kind of roles people in their team need to play. Should your team be very diverse or very deep in a given area? How do we integrate people who have different cultural backgrounds or how do we integrate medical students with PhD students? We brought in a lot of people out of the non-academic environment who were practitioners and experts in their various areas and we tried to get students to think about the full range of stakeholders they would have to engage with to bring a solution to bear.We did not want to spend a lot of time lecturing the students in a purely didactic way. We wanted to engage them in a process where they were solving important problems as part of the class. Whether that was a class on modelling or an engineering-focused class, or how to think about scientific problems, the core of DTE was built around getting the students to grapple with a real world problem and let all the learning hang off that.How did the students respond to that? Do you think you were successful?Based on the number of students signing up to take the courses and the student evaluations after the classes were over, I think we really struck a chord. I wouldn''t say it was necessarily the right answer for every student but I think there is clearly a group of students for whom this is a really effective and motivating approach.Let''s now move to drug discovery and development – the focus of the new online Special Collection from DMM. What would you say are some of the most urgent challenges in drug development that you have seen?I think one of the most urgent challenges is to begin to break free of some of our ‘old’ ways of thinking and take advantage of new scientific insights. For example, if you look at the traditional organization in a medical school environment, they are centered around departments devoted to organs (liver, heart, kidney). I think our increasing scientific understanding is that there are disease processes that may impact multiple organ systems but ultimately it is understanding the process, and drugging the process, that becomes important and not drugging the organ.I think that moving towards a process-oriented understanding of what common mechanisms are implicated in a given disease state or therapeutic challenge will help us be a little more creative and a little bit more interdisciplinary in how we think about these challenges.One of the difficulties with those new approaches is that pharmaceutical companies and academic institutions have not had a great track record of working together. Do you think that''s true? And why do you think it''s been so difficult to move ideas from the bench to the clinics?I think this is complicated. If you take the academic researchers'' point of view, their early identification of a problem and early identification of a potential solution feels like they have moved the ball very far forward towards the end solution. If you take industry''s point of view, the identification of the target or even the identification of a potential chemical compound is really just barely beginning to get to the starting line; the bulk of the time and the bulk of the dollars that will ultimately be needed to create a product come after the academic work and these will be spent by industry. I think that this differing point of view around where and how value is created has a lot to do with many of the challenges that arise when academia and industry are speaking to each other.Is it important to bridge this gap or is everybody playing their role?I think there''s an opportunity for academia to continue in its current role but to carry the potential solution further. I think in certain areas the access to tools and to patients allows academics to maybe carry projects further and closer to ‘proof of concept’ than they did historically, and that will continue to add value to the academic institution. That would ultimately help to bridge this gap because if you''ve taken something closer to proof of concept while still within the academic institution, you have created more value, you are able to engage with industry differently, and maybe the value perception gap is closed somewhat.What industry is really good at is organizing and managing late-stage research and clinical trials in an effective manner, and what academia is really good at is understanding basic questions, finding targets and sometimes finding early chemical compounds. Again, I think that the perception in academia of where value has been created is in part related to the fact that many academics haven''t been given the exposure or the training to actually understand the full breadth of the drug-development process. While they may have a general sense of it – we have all seen the same diagrams showing the steps and the funnel narrowing down from a million compounds to something getting onto the market – only those with real exposure to the work in industry understand it at a visceral or experiential level. One of the opportunities for academia is to find better ways to have some cross-talk, whether that''s internships for graduate students to get some experience in industry or other ways to get the students really exposed to the industrial side of drug development. Obviously, all the trained scientists on the industry side have been through academia because they had to go through it to get their PhDs, and thus they understand the academic side of the house pretty well. I really think the challenge is getting to people who have spent their whole career in academia to have a better understanding of what the drivers are on the industry side.
“One of the opportunities for academia is to find better ways to have some cross-talk, whether that''s internships for graduate students to get some experience in industry or other ways to get the students really exposed to the industrial side of drug development”Between target identification and clinical trials of course there is another piece. At what point does the researcher in academia put down his pipette, walk out and start a biotech company? Should that happen?That''s a fraught question because I think it is an enormous undertaking to start a biotechnology company. Fundraising, intellectual property, regulatory affairs, company management – there are a whole number of disciplines that biotech companies have to take on. It is very rare that an academic scientist is going to have the training, the time and the motivation to do all of those things while also continuing to pursue their academic career in a very challenging funding environment. I think it comes back to this point that we were talking about with teams. I think it is really important for a scientist who is excited about their work and thinks it may be the basis of a company to go out and begin to form a team that is going to increase the likelihood of success. They have to accept the fact that science is a critical component, but it is just a component, and many different disciplines along with many different people are needed to make a successful company. If a scientist can bring that sort of collaborative view point and is open to working closely with an intellectual property attorney, with a business development person and with whomever their funding source is, that will increase their likelihood of success. They have to do it with a certain amount of humility, which is to say that it isn''t just going to be the science that drives the success: all the given pieces have to come together to be successful.You''ve watched a lot of technology coming through, including at your new position at Mars. Which technology excites you?We all have to pay a lot of attention to CRISPR and the gene-editing technologies. There is certainly a number of intellectual property issues that have to get sorted out but that''s clearly an area that will have a huge impact not just on human health but on animal health and plant health as well.The other area I''ve been thinking a lot about lately is the microbiome. As sequencing technology has altered in cost and time, we have begun to be able to explore the microbiome in a way that historically was not possible. And it feels like we are moving towards a tipping point where the explosion of understanding is going to open up a lot of interesting opportunities for us to intervene. Whether that''s through traditional drug modalities or through altered nutrition or through changing the microbial community in soil to produce crops that have higher nutrient value or other approaches, I think that''s another broad area that seems poised to begin to offer really interesting results.Were you surprised that a company like Mars, which has not been a basic research company at all, is now giving you an opportunity to build something that is much more research-orientated?The reality of Mars is that they have actually had a very deep fundamental research program for a number of years. They got involved in the sequencing of the cacao genome and contributed it to the public domain, and they are now also involved in the sequencing of the genomes of a large number of orphan crops in Africa. So they have been very active in their research both in the company and in collaboration with academic scientists around the world. The nature of the company has meant that the work is perhaps not as obvious as others, but it is a remarkably science-driven company in much of what it does.You have done a myriad of things. What are the one or two things that you are most proud of?I am most proud of my efforts to keep a hand in both the commercial and the academic world. It certainly has not been easy but I have received enormous satisfaction from the opportunity to work with bright students at each of the schools I have had the opportunity to teach at. I am not sure there is anything more satisfying than the opportunity to work with students and feel you have helped them towards their goals.At the same time, I think I''ve been effective in doing that because I have managed to keep an active role in the applied world. In some ways, my greatest achievement has been finding a way to balance those two interests in a way that seems to have worked for the various organizations I''ve been affiliated with.How do you relax away from work? Do you have a family?I am married. My wife is a securities litigator so has a very active career of her own. We have two children, one in high school and one in middle school. I''ve had the privilege to coach both of them on their various soccer teams since they were each about 4 years old so that''s been a lot of fun.The other thing that many people will not find relaxing – but for some reason my family does – has been taking backcountry ski trips annually for a number of years. Worrying about navigating through the snow and finding shelter before darkness falls has a way of clearing the mind. 相似文献

Unconventional therapies (UTs) are therapies not usually provided by Canadian physicians or other conventionally trained health care providers. Examples of common UTs available in Canada are herbal preparations, reflexology, acupuncture and traditional Chinese medicine. UTs may be used along with conventional therapies (complementary) or instead of conventional therapies (alternative). Surveys have shown that many Canadians use UTs, usually as complementary therapies, for a wide range of diseases and conditions. Reliable information about UTs is often difficult to find. Your doctor may be unable to give you specific advice or recommendations, since UTs are often not in a physician''s area of expertise. However, he or she will usually be able to provide some general advice and help supervise your progress. For your own health and safety, it is important to keep your doctor informed of the choices you make. This document is intended to (a) provide you with questions to consider when making your treatment choices, (b) help you find information about UTs, (c) help you decide whether a specific UT is right for you, and (d) provide tips to help you evaluate the information you find. 相似文献
