Ways and Meanings of Coding Sense

In communication the task is not limited to formulating a system of meanings that transmit a thought. The internal subtext or sense has to be conveyed as well. What means, especially nonlinguistic means and techniques, are available for conveying subtext? An actor's training helps us to master these means. Stanislavsky emphasized the necessity to comprehend the entire semantic situation behind a role. Concrete characters from well-known plays are used to demonstrate different means and techniques.     

A Tribute to Thomas A. Sebeok

According to the approach developed by Thomas A. Sebeok (1921–2001) and his ‘global semiotics,’ semiosis and life converge. This leads to his cardinal axiom: ‘semiosis is the criterial attribute of life.’ His global approach to sign life presupposes his critique of anthropocentrism and glottocentrism. Global semiotics is open to zoosemiotics, indeed, even more broadly, biosemiotics which extends its gaze to semiosis in the whole living universe to include the realms of macro- and microorganisms. In Sebeok’s conception, the sign science is not only the study of communication in culture, but of communicative behaviour from a biosemiotic perspective.     

On the legacy of W.S. McCulloch

In this paper, we review McCulloch's legacy, from his early work in neurophysiology, and its relationship to his philosophical quest for an 'experimental epistemology' to his role in the cybernetics movement during the 1940s and 1950s and his contributions to the development of computer science and communication theory. There are three parts in chronological sequence. First, the period up to his work at Yale University with Dusser de Barenne, where he concentrated on the experimental study of the functional organization of sensory cortex. Second, the time of his Psychiatric Chair at the University of Chicago and the organization of the Macy Foundation Conferences. To this period corresponds the genesis and publication of the most influential and quoted work by McCulloch and Pitts: A Logical Calculus of the Ideas Immanent in Neurons Activity. Third, the period of his research activity at the Massachussetts Institute of Technology where he, Lettvin, Maturana and Pitts produced epochmaking papers on epistemological neurophysiology, the modelling of the reticular formation and other work with da Fonseca and Moreno-Díaz. We finally refer to the International Conference that took place in McCulloch's memory at the 25th anniversary of his death. Our main conclusion is that McCulloch's writings are still a source of inspiration from neurophysiology to artificial intelligence and robotics.     

Talking biotech with the public

In the estimation of risks involved in complex technical applications, such as, for example, gene technology or nanotechnology, the problem of communication between science and the wider society becomes evident. The path towards transparent, authentic and credible communication must be built upon the reconciliation of the risk perceptions of the scientist--and of his or her institution--with the corresponding ideas of risk and communication existing in the society. Additionally, to accomplish goal-oriented discourse within the public sphere and to realistically assess his or her effective options when addressing this public, the scientist is faced with the necessity of reflecting upon his or her own determining assumptions on the condition, constitution and functionalities of this "public". Combined with the use of modern tools--and supported with supplementary coaching and organizational consultation--such a foundation allows the establishment of targeted communication with specific groups.     

Philip R. White (1901–1968)—a tribute

The groundbreaking research carried out by Philip R. White in the 1930s and 1940s played a critical early role in the development of modern plant biotechnology and the production of biotech crops. He gained instant fame and became a historical figure early in his career by becoming the first person to attain unlimited growth of cultured plant tissues. White was one of the best known and most influential figures of his generation in plant cell culture research. His tireless and lifelong efforts to promote the use of plant cell culture systems inspired a generation of scientists and stimulated much scientific activity. White was not only a brilliant and visionary scientist but also a highly principled man who spoke courageously about the great moral and political issues of his day. He was admired as much for his science as for his humanity. His belief that plant cell culture research was not well represented at national and international meetings, and his deeply held conviction that science had to be international and without borders in order to be of service to humankind led to the founding of the International Association for Plant Biotechnology in 1963, currently the largest forum for the international plant biotechnology community. This tribute honors and celebrates Philip R. White for his inspiring science, for his kind and generous mentoring of young scientists, for his advocacy of plant cell culture research and its applications, for his promotion of international scientific exchange and cooperation, and for his leadership in the founding of the International Association for Plant Biotechnology.     

Darwin: Origin and Evolution of an Exhibition

Two hundred years after his birth, Darwin, originated by the American Museum of Natural History in New York, is the most important exhibition about the English scientist ever organized for the general public. This traveling exhibition has appeared in many versions worldwide, and a study of the relationships between local developers of the various editions of the exhibition underlines how a scientific exhibition and, more generally, science communication can succeed in striking a good equilibrium between universal content and cultural determinants.     

The interface of natural theology and science in the ethology of W. H. Thorpe

Conclusion It should be clear by now the extent to which many features of Thorpe's interpretation of animal behavior and of the animal mind rested, at bottom, not simply on conventional scientific proofs but on interpretive inferences, which in turn rested on a willingress to make extensions of human experience to animals. This, in turn, rested on his view of evolution and his view of reality. And these were governed by his natural theology, which was the fundamental stratum of his intellectual experience.Contrary to the scientific ethos, which restricts theory choice to scientific issues alone, Thorpe's career suggests that the actual reasons for theory choice among scientists often are not limited to science, but are multiple and may sometimes be difficult to discover. It is largely because Thorpe took a public part in the natural theology enterprise that we can know something about his religious beliefs and so can see their probable influence on his scientific decisions. Similar beliefs of other scientists are sometimes harder to get at. Most may be practically beyond discovery, for the ethos of science has discouraged public professions of personal belief in relation to scientific work.¹⁰¹ Yet does it seem plausible that, for example, the restriction of self-consciousness to humans by some scientists is a purely scientific decision?¹⁰² Surely not, any more than that the strong influence of natural theology on Thorpe's thought means that he was not a good scientist. His natural theology may have led him into incautious enthusiasms regarding the animal mind — such as the potential if unrealizable linguistic ability of chimpanzees — through a bias in favor of the continuity of emergents in a progressive evolutionary system, just as it led him to advocate animal consciousness long before the recent upsurge of interest, but the scientific integrity of his work overall is unimpeachable. And yet, that work is not comprehensible historically as science alone. Personal philosophy must not be discounted in writing the history of recent science. This somewhat obvious conclusion (obvious to historians of science) needs emphasis, for we are still prone to think that the sciences of our own time provide their own internal dynamic that is in itself sufficient to account for their content and development.     

How serendipity shaped a life; an interview with John W. Saunders,Jr. by John F. Fallon

John W. Saunders Jr. is an outstanding contributor to the field of Developmental Biology. His analyses of the apical ectodermal ridge, discovery and study of the zone of polarizing activity, insights into cell death in development, and analytical studies of feather patterns are part of a legacy to developmental biology. The body of his published work remains central to the understanding of limb development and is a major reason for the premiere place that the developmental biology of limbs holds in our research and teaching today. Beyond these things known to nearly everyone, there is John's role as teacher that is equally impressive. His one-on-one style, in small groups or from the podium is engaging, encompassing, and above all else, enthusiastic about the study of the development of living things. His love of developmental biology comes through to students of all ages and is inspirational. And, of course, inimitable charm accompanies the substance of any interaction with John. He still teaches in the Embryology Course at MBL Woods Hole. Recent students say that hearing his lectures and his involvement in the laboratory are highlights of the course. His continued knowledge of science and delight in new advances is a model for students to follow and they recognize it. John Saunders is a scientist and educator par excellence. His contributions have stood the test of time. His personal interactions with colleagues and students have enriched their lives in innumerable ways, large and small. His is a lifetime of outstanding achievements. In this interview, he reflects on his six--going on seven--decades in science and his personal enjoyment of recent advances in Developmental Biology.     

Scientists’ Prioritization of Communication Objectives for Public Engagement

Amid calls from scientific leaders for their colleagues to become more effective public communicators, this study examines the objectives that scientists’ report drive their public engagement behaviors. We explore how scientists evaluate five specific communication objectives, which include informing the public about science, exciting the public about science, strengthening the public’s trust in science, tailoring messages about science, and defending science from misinformation. We use insights from extant research, the theory of planned behavior, and procedural justice theory to identify likely predictors of scientists'' views about these communication objectives. Results show that scientists most prioritize communication designed to defend science from misinformation and educate the public about science, and least prioritize communication that seeks to build trust and establish resonance with the public. Regression analyses reveal factors associated with scientists who prioritize each of the five specific communication objectives. Our findings highlight the need for communication trainers to help scientists select specific communication objectives for particular contexts and audiences.     

Warmest Congratulations to Dr. Yuan-Cheng Fung at His Centennial Celebration

Professor Y.C. Fung has made tremendous impacts on science, engineering and humanity through his research and its applications, by setting the highest standards, through educating many students and their students, and providing his exemplary leadership. He has applied his profound knowledge and elegant analytical methods to the study of biomedical problems with rigor and excellence. He established the foundations of biomechanics in living tissues and organs. Through his vision of the power of “making models” to explain and predict biological phenomena, Dr. Fung opened up new vista for bioengineering, from organs-systems to molecules-genes, and has provided the foundation of research activities in many institutions in the United States and the world. He has made outstanding contributions to education in bioengineering, service to professional organizations, and translation to industry and clinical medicine. He is widely recognized as the Father of Biomechanics and the leading Bioengineer in the world. His extraordinary achievements and commands in science, engineering and the arts make him a Renaissance Man for the world.     

Experimentation, communication and patronage: a perspective on René-Antoine Ferchault de Réaumur (1683-1757)

Historians of science have neglected the French Academician Réaumur, whose work is emblematic of a modern conception of science that joins together technology, science, and society. Réaumur practised rigorous experimentation on organisms, and uncovered industrial and utilitarian secrets which he communicated to the public. His patronage was essential in boosting the generation of young naturalists of the 1740s who advanced further the experimental approach to the study of nature. For Réaumur, his work was not separate from his mission to disclose and communicate previously restricted knowledge for the benefits of science and society.     

Conception et suites de la Paléontologie française d’Alcide d’Orbigny

The whole formed by his Paléontologie française, his Prodrome, and his Cours élémentaire, which are closely linked, constitutes one of the major parts of Alcide d’Orbigny’s scientific production, in which he exposed his concept of Palaeontology as a science closely related with Zoology and as an indispensable tool for Stratigraphy. The result was a remarkable impulsion for palaeontological and stratigraphical research, which from that time developed on new scientific foundations. Two annexes complete this communication, the first concerning the ‘Comité de la Paléontologie française’ (1860–1893), the second specifying the publication dates of four volumes of the Paléontologie française.     

N. I. Vavilov-the man and his work

A brief sketch is presented of Vavilov's career, his main contributions to science and personal qualities. The imporatnce of his work in genetics, agro-ecology, plant breeding, the experimental taxonomy of crop plants and genetic resources conservation is also emphasized.     

Ulisse Aldrovandi (1522–1605): The Study of Trace Fossils During the Renaissance

The Renaissance was a time of flourishing for literature, art and science. A prominent figure in Renaissance science was the Italian naturalist Ulisse Aldrovandi, considered today to be one of the founding fathers of modern paleontology. Aldrovandi is known to have widely studied body fossils, but his work on trace fossils has yet to be explored by science historians. This paper proposes to critically analyze Aldrovandi's approach to trace fossils, based on his writings (most of which are still unpublished) and on the illustrations that accompany them. In his studies, the Bologna-born naturalist accurately describes such ichnological celebrities as Gastrochaenolites and Cosmorhaphe and discusses a few theoretic principles on the trace-making process. The study of the works of Aldrovandi brings to light a fascinating and little-known source of the history of ichnology.     

In memorium: Herman p. Schwan [1915-2005

Herman P. Schwan [1915-2005] was a distinguished scientist and engineer, and a founding father of the field of biomedical engineering. A man of integrity, Schwan influenced the lives of many, including his wife and children, and his many students and colleagues. Active in science until nearly the end of his life, he will be very much missed by his family and many colleagues.     

Medicine or Science—A Study of Career Decisions

A study of the career decisions of all students in a single matriculation cohort was undertaken in 1965 at the University of British Columbia. Studied were 64 premedical students, 112 ex-premedical students and 87 science students who had completed at least their second year. It was found by means of a questionnaire that medicine remained the career of high prestige for the three groups of students. In general the values and needs of the ex-premedical student were more similar to those of the science student than the premedical student. The loyalists to medicine were found to be more committed, self-assured, and orientated towards people and service. In addition, the premedical student was more concerned about his academic achievement but was also more confident of his progress. He emerged at the end of his training as the committed student who had chosen medicine at an early age and had remained loyal to his chosen career goal.     

Challenges and opportunities for biogeography—What can we still learn from von Humboldt?

Alexander von Humboldt was arguably the most influential scientist of his day. Although his fame has since lessened relative to some of his contemporaries, we argue that his influence remains strong—mainly because his approach to science inspired others and was instrumental in furthering other scientific disciplines (such as evolution, through Darwin, and conservation science, through Muir)—and that he changed the way that large areas of science are done and communicated. Indeed, he has been called the father of a range of fields, including environmental science, earth system science, plant geography, ecology and conservation. His approach was characterized by making connections between non‐living and living nature (including humans), based on interdisciplinary thinking and informed by large amounts of data from systematic, accurate measurements in a geographical framework. Although his approach largely lacked an evolutionary perspective, he was fundamental to creating the circumstances for Darwin and Wallace to advance evolutionary science. He devoted considerable effort illustrating, communicating and popularizing science, centred on the excitement of pure science. In biogeography, his influence remains strong, including in relating climate to species distributions (e.g. biomes and latitudinal and elevational gradients) and in the use of remote sensing and species distribution modelling in macroecology. However, some key aspects of his approach have faded, particularly as science fragmented into specific disciplines and became more reductionist. We argue that asking questions in a more Humboldtian way is important for addressing current global challenges. This is well‐exemplified by researching links between geodiversity and biodiversity. Progress on this can be made by (a) systematic data collection to improve our knowledge of biodiversity and geodiversity around the world; (b) improving our understanding of the linkages between biodiversity and geodiversity; and (c) developing our understanding of the interactions of geological, biological, ecological, environmental and evolutionary processes in biogeography.     

John Tileston Edsall: some selected biography and personal reminiscences

This paper has been written in honor of John T. Edsall. Its purpose is to review briefly the status of science during his active years and the combination of personal qualities and upbringing which resulted in his enormous impact on the field of biochemistry. There was an unusual combination of deep knowledge and interest in many intellectual areas by no means restricted to science; the large number of individuals he met by intent or by chance, many to become fast friends for life, who themselves became distinguished in science; and last but not least his influence on science policy through very clear statements and his moral positions on questions of the day.     

Ernst Mayr,naturalist: His contributions to systematics and evolution

Ernst Mayr's scientific career continues strongly 70 years after he published his first scientific paper in 1923. He is primarily a naturalist and ornithologist which has influenced his basic approach in science and later in philosophy and history of science. Mayr studied at the Natural History Museum in Berlin with Professor E. Stresemann, a leader in the most progressive school of avian systematics of the time. The contracts gained through Stresemann were central to Mayr's participation in a three year expedition to New Guinea and The Solomons, and the offer of a position in the Department of Ornithology, American Museum of Natural History, beginning in 1931. At the AMNH, Mayr was able to blend the best of the academic traditions of Europe with those of North America in developing a unified research program in biodiversity embracing systematics, biogeography and nomenclature. His tasks at the AMNH were to curate and study the huge collections amassed by the Whitney South Sea Expedition plus the just purchased Rothschild collection of birds. These studies provided Mayr with the empirical foundation essential for his 1942Systematics and the Origin of Species and his subsequent theoretical work in evolutionary biology as well as all his later work in the philosophy and history of science. Without a detailed understanding of Mayr's empirical systematic and biogeographic work, one cannot possibly comprehend fully his immense contributions to evolutionary biology and his later analyses in the philosophy and history of science.
