Dogs were tested (1) in a two‐way choice experiment, where the experimenter indicated a baited bowl by pointing; and (2) in a task where the owner was asked to command the dog to execute simple obedience tasks. In expt 1 dogs (n = 10) were tested at first in the presence of the experimenter (three dimensional condition, 3D), that was followed by a series of pointing trials when the life‐sized image of the experimenter was projected onto the wall by the means of a video‐projector (two dimensional condition, 2D). Dogs performed correctly more often than expected by chance in both 3D and 2D conditions. In expt 2 the commanding owner was either present in the room (3D), or her/his image was projected on the screen (2D), or only her/his voice was audible for the dog through a speaker (0D). The performance of the dogs (n = 10) decreased to great extent comparing the 3D and 0D condition, as the number of different actions the dogs obeyed was significantly less in the 0D condition. However, there was no difference in the number of different actions obeyed in the 3D and 2D conditions. Our results show that dogs readily obey life‐sized, interactive moving image in various communicative situtations. We suppose that the difference between 2D and 3D conditions can be attributed partially to the lack of some additional communicative signals as sounds (verbal cues) and odours (from the human), and to some changes in the context. 相似文献

An appetizing smell of beetroot soup came wafting from the kitchen, with it the rhythmic sound of chopping... Ye Zhiqiu ... was in a mood to play some prank out of keeping with her age... So she tried to repress her elation, to behave like a middle-aged Chinese woman. Perhaps she didn't try hard enough, for a little of it came bubbling out as she called in her rusty French, “Qu'est-ce qu'on mange au dejeuner?” Mo Zheng promptly called back from the kitchen, “De la soupe au potiron, de saucisson et du pain.” Good lad, he hadn't forgotten his French. That came of his upbringing in a cultured family.1 相似文献

Social referencing is a process whereby an individual uses the emotional information provided by an informant about a novel object/stimulus to guide his/her own future behaviour towards it. In this study adult dogs were tested in a social referencing paradigm involving a potentially scary object with either their owner or a stranger acting as the informant and delivering either a positive or negative emotional message. The aim was to evaluate the influence of the informant''s identity on the dogs'' referential looking behaviour and behavioural regulation when the message was delivered using only vocal and facial emotional expressions. Results show that most dogs looked referentially at the informant, regardless of his/her identity. Furthermore, when the owner acted as the informant dogs that received a positive emotional message changed their behaviour, looking at him/her more often and spending more time approaching the object and close to it; conversely, dogs that were given a negative message took longer to approach the object and to interact with it. Fewer differences in the dog''s behaviour emerged when the informant was the stranger, suggesting that the dog-informant relationship may influence the dog''s behavioural regulation. Results are discussed in relation to studies on human-dog communication, attachment, mood modification and joint attention. 相似文献

The sexual behaviour of Triturus cristatus is described. The first stage of sexual behaviour consists of an orientation phase in which the male approaches the female, sniffs her and moves in front of and perpendicular to her. The second stage is a prolonged period of static display with two different tail movements, called Fan and Lash, in 13.8 ± 1.3 bouts (x? ± SE) with intervals of 10.5 ± 0.3 s between bouts. Each bout contains 6.7 ± 0.3 regular Fan beats at a frequency of 0.5–0.8 Hz. This Fanning provides olfactory and mechanical stimulation to the female. 15% of bouts also contain a violent Lash, in which the male rapidly slaps the female's flank. Some Lashes are used to stop the female when she tries to move away. In the third stage of the sexual sequence, the male turns away, Creeps for 6.7 ± 0.3 s (x? ± SE) and then Quivers his tail. A receptive female follows and touches his tail, and the male deposits a spermatophore and then turns to one side with his tail folded along his flank in a position called Brake. The female now approaches again and the male steps away sideways in a movement called Rebrake. After several Rebrakes the male stops, the female touches his tail and the spermatophore may now be picked up in her cloaca. This sequence can be repeated several times during one encounter. This behaviour is discussed in relation to previous studies of courtship in this genus. 相似文献

When Queen Elizabeth is at home in Buckingham Palace, tradition has it that the Royal Standard is raised, so that all may know the fact. Although it is not crucial for most of us to know whether Her Majesty is home, it is in social insects. Endler et al. have recently shown how an ant queen signals her presence to her remote workers: she marks her eggs. This is significant because it provides insight into how queens maintain reproductive monopoly within their colonies. 相似文献

A finely worked bronze dog has been standing on my desk for twenty years now. Aside from the books with their dedicatory signatures, it is the only material thing I have in memory of Aleksandr Romanovich Luria. A week after he died, Lana Pimenovna, his wife, asked if I could drop in to see her. I thought that the reason for her call—to ask me to enlarge, reproduce, and frame some photos she had made of Aleksandr Romanovich in various years during his lifetime—was only a pretext: the publisher's in-house photographer or any other photographer could have done this. 相似文献

Angela Roddey Holder 《The Yale journal of biology and medicine》2010,83(1):35-41
Angela Holder was to give the Grover Powers Memorial Lecture at the weekly Grand Rounds conducted by the Yale Department of Pediatrics on Wednesday, May 27, 2009, but unfortunately, she died one month earlier, on April 22, leaving behind her prepared address, “From Chattel to Consenter: Adolescents and Informed Consent,” which she had regarded as the pinnacle of a remarkable career, much of it spent at Yale. As the Grover Powers honoree, the department’s highest honor, Ms. Holder was only the fourth woman of 46 recipients and the first who was not a physician. On the date scheduled for her address, tributes were presented by her son, John Holder, and her longtime colleague, Dr. Robert Levine, co-founder of Yale’s Interdisciplinary Bioethics Center. Their comments follow Angela Holder’s completed but undelivered Grover Powers address. — Myron Genel, MD, Professor Emeritus of PediatricsUnder the common law of England and in the early years of the United States, a minor (defined as anyone under 21) was a chattel or possession of his or her father [1-4]. A father had the right to sue a physician who treated his son or daughter perfectly properly but without the father’s permission because such an intervention contravened the father’s right to control the child. Beginning in the early years of the 20th century, by the end of World War II and into the 1950s, the notion that a 16-year-old was a legally different entity from a 6-year-old gradually became law in all states.1 The first hospital unit for adolescents was created in 1951 at Boston Children’s Hospital, and the concept of “adolescent medicine” was born [5].As the law in this area currently defines “adolescent,” we are discussing someone 14 or older who may be (1) living at home with his or her parents; (2) Not living at home but still dependent on parents (i.e., a 16-year-old college freshman living in a dorm); (3) an “emancipated minor” who is married, emancipated by a court order, or a parent (other than in North Carolina), living away from home and self-supporting; or (4) a runaway or throwaway. At any time in this country, there are about 200,000 adolescents living on the streets with no adult supervision or involvement [6].Regardless of the age of the patient, informed consent consists of five elements: (1) An explanation of what will happen; (2) explanation of the risks; (3) explanation of the projected benefits; (4) alternatives (including doing nothing); and (5) why the physician thinks it should be done, which I interpret as a right to know one’s diagnosis. While the doctrine of “therapeutic privilege” means that in rare cases a physician may withhold some information from an adult patient if she or he believes the patient cannot “deal with the information,” there can never be any withholding of information from an adolescent. If the patient can’t deal with the information to be presented, then parents have to be involved and give permission to treat the adolescent.In some cases, when parents are involved, they do not want their adolescent to know his or her diagnosis. While this is usually not a good idea, it normally falls under the rubric of “professional judgment,” and the physician has every right to decide to follow the parents’ instruction if she agrees with it. In some situations, however, the adolescent must be told what his or her illness is, whether parents like it or not. For example, if a teenager is HIV positive, he or she must be told, must be instructed about safe sex, and must be asked to divulge the names of any sex partners. Parents who say, “Oh, no, don’t tell him, he would never do anything like that, so it doesn’t matter,” should be tactfully but firmly led to accept the fact that he may well have and if he hasn’t yet, he will certainly in the future. There has been at least one successful malpractice case in which the physician did not, at the request of the parents, tell his adolescent patient that he had HIV. The patient’s girlfriend caught it and sued the physician [7]. I feel sure there are many more cases like this that have been quietly settled and no one will ever hear about.Usually, questions about adolescents giving consent to treatments that their parents don’t know about involve outpatient treatment. In the first place, hospital administrators, who are much more interested in getting paid than they are in advancing the rights of autonomous adolescents, are not going to admit for a non-emergency problem a minor whose parent has not made some sort of financial arrangement to pay for it. Secondly, in most households, if Little Herman doesn’t show up for supper or throughout the evening, someone notices and a few telephone calls later discovers that Little Herman is in the hospital. 相似文献

Rapid vocabulary learning in children has been attributed to "fast mapping", with new words often claimed to be learned through a single presentation. As reported in 2004 in Science a border collie (Rico) not only learned to identify more than 200 words, but fast mapped the new words, remembering meanings after just one presentation. Our research tests the fast mapping interpretation of the Science paper based on Rico's results, while extending the demonstration of large vocabulary recognition to a lap dog. We tested a Yorkshire terrier (Bailey) with the same procedures as Rico, illustrating that Bailey accurately retrieved randomly selected toys from a set of 117 on voice command of the owner. Second we tested her retrieval based on two additional voices, one male, one female, with different accents that had never been involved in her training, again showing she was capable of recognition by voice command. Third, we did both exclusion-based training of new items (toys she had never seen before with names she had never heard before) embedded in a set of known items, with subsequent retention tests designed as in the Rico experiment. After Bailey succeeded on exclusion and retention tests, a crucial evaluation of true mapping tested items previously successfully retrieved in exclusion and retention, but now pitted against each other in a two-choice task. Bailey failed on the true mapping task repeatedly, illustrating that the claim of fast mapping in Rico had not been proven, because no true mapping task had ever been conducted with him. It appears that the task called retention in the Rico study only demonstrated success in retrieval by a process of extended exclusion. 相似文献

This paper provides a short history of Anna Fraentzel Celli life, from her arrival in Italy in 1898 to her death in 1958, reviewing available documents and written testimonies. Anna Fraentzel was born in Berlin in 1878, third of four daughters from a bourgeois family; her maternal grandfather, Luigi Traube, was a very well known physician, as well as her father Oscar, and she developed an early interest in medicine that she couldn't fulfill: actually after her father's death she was forced to shorten her education, she couldn't enter the medical school, as she would have liked to, and she attended the nursing school, instead, displaying a lot of good practical sense. As a nurse in Hamburg in 1896 she met Prof. Angelo Celli, who was there on a professional visit, and who assisted the young nurse in finding a job at the city hospital. She was much younger than him, who was already a middle aged respected scientist; anyhow, even after his departure, they kept in touch and eventually fell in love. They married in 1899 and she moved to Rome to work at the S. Spirito Hospital joining a brilliant group of physicians and researchers as Tommasi-Crudeli, Marchiafava, Bignami, Bastianelli, Dionisi, Grassi, and her husband Angelo. They had long been studying the mode of transmission of the malaria infection and in 1898 they had identified the mosquito Anopheles as the vector of the malaria parasite. She got enthusiastically involved both in the scientific work and in the antimalarial campaign which Celli promoted in the Agro Romano. The strong personality of Anna Celli, her active involvement in social problems, her passionate dedication to her work, her peculiar way of being feminist, expressed fully her commitment to the struggle against malaria and illiteracy in the Agro Romano and in the Paludi Pontine at the beginning of the twentieth century. She must be credited as a major force in the creation and functioning of the Peasant Schools, as well as in the organisation of the experimental antimalarial health clinics. After her husband's death in 1914 she continued as a promoter of the antimalarial campaign, co-operating with the Red Cross and other institutions. Moreover, she edited the scientific and historical papers which Angelo Celli had collected and written during his life. She was also a prolific writer and lecturer on these issues and gained widespread appreciation both in Italy and in Germany. Toward the end of her life she retired to a nursing home in Rome where she died almost alone in 1958. 相似文献

A 24-year-old mare exhibited abnormal behavior only when she was in estrus. She was subordinate to other mares. During diestrus she aggressed against an approaching stallion as a normal non-receptive mare would, but during estrus she flexed her limbs, clamped her tail and opened and closed her mouth when a stallion approached. The facial expression appeared when she first noticed the stallion or heard his neighs. The limb flexing occurred only when a stallion was in close proximity. The facial expression closely resembled snapping (also known as champing or tooth-clapping) of immature equids and jawing of receptive zebra and donkey mares.It is hypothesized that the mare's expression, the snapping of foals and the facial expression of donkeys and zebras are the same expression — one that indicates that the animal is in an approach—avoidance situation. In this case, the mare may have been both fearful of, and attracted to, stallions. 相似文献

Thirty-six persons -- veterinarians, technicians and students at a veterinary clinic -- were unwittingly exposed to a rabid dog over a period of 21/2 days. One veterinarian received a penetrating bite, two other individuals were grabbed by the dog but the skin was not penetrated, and many were exposed to saliva or urine or both. In addition, the owner of the dog and his wife and three children, while not bitten, were exposed to saliva. The diagnosis was made post mortem when specimens of the dog''s brain were examined by indirect fluorescent antibody testing. All but one of the students had been vaccinated against rabies with hamster kidney vaccine, but eight members of the veterinary college''s staff had not been so vaccinated. Treatment started with duck embryo vaccine; if necessary, rabies (human) immune globulin was also given. When one student reacted severely to the first dose of duck embryo vaccine permission was sought to bring a human diploid vaccine into Canada. In five patients the human diploid vaccine was substituted for the duck embryo vaccine because of severe reactions to the latter. Twenty-five staff members and the family of five received both vaccines. Reactions to the human diploid vaccine were minor and transient. Recommendations include the early licensing of the human diploid vaccine in Canada. 相似文献

ABSTRACTAlthough several studies have shown perceived facial resemblance between photos of purebred dogs and their owners, none of these studies has clarified which part of the face is critical for such an impression to arise. The series of experiments presented here identified the critical feature underlying the perceived dog–owner facial resemblance. In total, 502 Japanese undergraduate students participated in the study. Two sets of 20 dog–owner photo pairs had been color-printed on a test sheet: the dogs varied in breed and the owners were Japanese males and females in their twenties to sixtieswho were unknown to the participants. One set comprised real pairs, while the other was a fake set (i. e., each dog was paired with another dog's owner). As in a previous study, the majority of participants (from two-thirds to three-quarters) reported that the former set was more similar than the latter. This was also the case even when the mouth regions of the owners' faces were masked by black bars. However, masking the eye regions of either dogs or owners reduced the choice performance to a chance level of around 50%. Furthermore, choice performance was equally good and above the chance level, regardless of whether the entire faces were shown or only the eye regions of the dogs and owners were visible. These results strongly suggest that dogs and owners resemble each other in the eye region. This finding also ruled out the possibility that any nonphysiognomic features (e. g., owners' hairstyles and people's stereotypical concepts about dog ownership) or similarity of obesity are determinate for the perceived dog–owner resemblance. 相似文献

The players all played at once, without waiting for turns, quarreling all the while and fighting for the hedgehogs; and in a very short time the queen was in a furious passion and went stamping about, and shouting “off with his head” or “off with her head,” about once a minute. Alice began to feel very uneasy: to be sure she had not as yet had any dispute with the queen, but she knew that it might happen any minute, “and then” thought she, “what would become of me? They're dreadfully fond of beheading people here: the great wonder is, that there's any one left alive”. 相似文献

The guide dog partnership begins at the point of matching, when careful assessment of a trained guide dog and an understanding of the functional needs and expectations of the prospective owner are considered alongside each other. Guide Dogs UK invest much time and resources to the process of matching a client with a dog in order to fulfil client expectations and create a lasting partnership. This study explores: (1) the meaning and importance of social (non-working) behavior to guide dog owners; (2) how firsthand experience and knowledge shape individual owner expectations for behavior; and (3) how, and in what ways, social behavior impacts the guide dog partnership. The focus group method was used to collect qualitative data from a total of 11 participants. The data were analyzed using a thematic analysis procedure which identified six overarching themes: “social behavior to me means,” internal and external factors influencing social behavior, training and matching, socially desirable and undesirable behaviors, maintaining and managing social behavior, and practical and emotional issues. Findings show that social behavior is as important as guiding skills and mobility for guide dog owners, and behavioral compatibility is held to be crucial in a successful partnership. Participants put an emphasis on consistency of behavior in social settings, while recognizing that a guide dog's non-working behavior is subject to multifarious internal and external influences. The findings of this study indicate an opportunity for Guide Dogs UK, and similar assistance dog organizations, to observe fully the importance of social behavior and, in response, place even greater emphasis on lifestyle and behavioral compatibility when training dogs and matching them with clients. 相似文献

ABSTRACTPolicy and campaigning messages related to dog ownership and welfare center on the concept of responsible ownership. However, the perspectives and experiences of pet owners and how they perceive and perform their responsibilities has not been studied in depth. This qualitative study used conversations about owning and walking dogs in order to elucidate beliefs and views about responsibility in dog ownership. Data comprised 12 in-depth interviews with dog-owning households, 14 short interviews with dog owners while walking their dogs or representing their breed at a dog show, and autoethnography of the first author’s experiences owning and walking dogs. All participants considered themselves responsible dog owners, yet there was great variation in key aspects of their dog-owning behavior. The feelings of responsibility were rooted in the valued unconditional and reciprocal love that owners believed underpinned their human–dog bond. Dogs were described as dependents, similar to, but different from, children. In deciding how to look after their dogs, owners sought to balance their views of dogs as kin, having individual needs to be met, with consideration of the needs of others. Four processes through which issues of irresponsible dog ownership may arise were suggested: owner–dog relationship being too weak or too strong; differences in interpretation of what is best for the dog; difficulties predicting and avoiding situations of conflict; and differences in tolerance of negative impacts of dog ownership. While “responsible dog ownership” has considerable appeal as a concept, how it is perceived and interpreted varies so extensively that simply telling owners that they should “be responsible” is of limited use as a message to promote behavior change. Facilitating “responsible dog ownership” and reducing “irresponsible dog owner” behaviors relies on a detailed understanding of the variables which influence how the dog’s role is constructed within the family and the wider society. 相似文献

A contribution to a special issue on Hormones and Human Competition.A stress perspective is used to illuminate how competitive defeat and victory shape biology and behavior. We report a field study examining how change in cortisol following perceived defeat (vs. victory) in a competition—in this case, a dog agility competition—relates to affiliative behavior. Following competition, we measured cortisol change and the extent to which dog handlers directed affiliative behaviors toward their dogs. We found striking sex differences in affiliation. First, men were more affiliative toward their dogs after victory, whereas women were more affiliative after defeat. Second, the greater a female competitor's increase in cortisol, the more time she spent affiliating with her dog, whereas for men, the pattern was the exact opposite: the greater a male competitor's increase in cortisol, the less time he spent affiliating with his dog. This pattern suggests that, in the wake of competition, men and women's affiliative behavior may serve different functions—shared celebration for men; shared consolation for women. These sex differences show not only that men and women react very differently to victory and defeat, but also that equivalent changes in cortisol across the sexes are associated with strikingly different behavioral consequences for men and women. 相似文献

As the world watched the Fukushima reactors release radionuclides into the ocean and atmosphere, the warnings of Dr. Alice Stewart about radiation risk and the reassurances of Sir Richard Doll assumed renewed relevance. Doll and Stewart, pioneer cancer epidemiologists who made major contributions in the 1950s-he by demonstrating the link between lung cancer and smoking, she by discovering that fetal X-rays double the chance of a childhood cancer-were locked into opposition about low-dose radiation risk. When she went public with the discovery that radiation at a fraction of the dose "known" to be dangerous could kill a child, her reputation plummeted, whereas Doll, foremost among her detractors, was knighted and lauded as "the world's most distinguished medical epidemiologist" for his work. Their lives and careers, so closely intertwined, took contrary courses, he becoming "more of the establishment" (as he said), while she became more oppositional. When it was discovered, after his death, that he'd been taking large sums of money from industries whose chemicals he was clearing of cancer risk, his reputation remained unscathed; it is now enshrined in the "Authorized Biography" (2009) commissioned by the Wellcome Institute, along with Doll's denigration of Stewart as an "embittered" woman and biased scientist. Stewart lived long enough to see radiation science move her way, to see international committees affirm, in the 1990s, that there is no threshold beneath which radiation ceases to be dangerous; recent evidence from Chernobyl is bearing out her warnings. But a look at the making and breaking of these reputations reveals the power of status, position, and image to shape scientific "knowledge" and social policy. 相似文献
