Research in face recognition has tended to focus on discriminating between individuals, or “telling people apart.” It has recently become clear that it is also necessary to understand how images of the same person can vary, or “telling people together.” Learning a new face, and tracking its representation as it changes from unfamiliar to familiar, involves an abstraction of the variability in different images of that person's face. Here, we present an application of principal components analysis computed across different photos (...) of the same person. We demonstrate that people vary in systematic ways, and that this variability is idiosyncratic—the dimensions of variability in one face do not generalize well to another. Learning a new face therefore entails learning how that face varies. We present evidence for this proposal and suggest that it provides an explanation for various effects in face recognition. We conclude by making a number of testable predictions derived from this framework. (shrink)

This article describes some differences between familiar and unfamiliar face processing. It presents the evidence that unfamiliar face recognition is poor. Since this poor performance has implications both practically and theoretically, it is important to establish the facts. The article analyses reasons that people appear to have little insight into their own poor performance with unfamiliar faces, and some sectors of society seem so keen to use faces as a means of proving identity. It reviews some historical research comparing familiar (...) and unfamiliar face processing. The study shows evidence for the assertion that despite eliminating the memory-load of normal eyewitness situations, it turns out that people are surprisingly bad at matching two images of the same unfamiliar person. Finally, it suggests that the modern tendency to conflate familiar and unfamiliar face processing, and to theorize about “face recognition” in general, lies at the heart of practical failures in this field.

Distributed representations can be distributed in very many ways. The specific choice of representation for a specific model is based on considerations unique to the area of study. General statements about the effectiveness of distributed models are therefore of little value. The popularity of these models is discussed, particularly with respect to reporting conventions.

Significant advances have been made in understanding human face recognition. However, a fundamental aspect of this process, how faces are located in our visual environment, is poorly understood and little studied. Here we examine the role of color in human face detection. We demonstrate that detection performance declines when color information is removed from faces, regardless of whether the surrounding scene context is rendered in color. Furthermore, faces rendered in unnatural colors are hard to detect, suggesting a role beyond simple (...) segmentation. When faces are presented such that half the surface is colored appropriately, and half unnaturally, performance declines. This suggests that observers are not simply using the presence of skin color “patches” to detect faces. Rather, our data suggest that detection operates via a face template combining diagnostic color and face‐shape information. These findings are consistent with color‐template approaches used in some computer‐based face detection systems. (shrink)

It is well established that retrieval of names is harder than the retrieval of other identity specific information. This paper offers a review of the more influential accounts put forward as explanations of why names are so difficult to retrieve. A series of five experiments tests a number of these accounts.Experiments One to Three examine the claims that names are hard to recall because they are typically meaningless, or unique. Participants are shown photographs of unfamiliar people or familiar people and (...) given three pieces of information about each: a name, a unique piece of information, and a shared piece of information. Learning follows an incidental procedure, and participants are given a surprise recall test. In each experiment shared information is recalled most often, followed by unique information, followed by name. Experiment Four tests both the `uniqueness' account and an account based on the specificity of the naming response. Participants are presented with famous faces and asked to categorise them by semantic group. Results indicate that less time is needed to perform this task when the group is a subset of a larger semantic category. A final experiment examines the claim that names might take longer to access because they are less often retrieved than other classes of information. Latencies show that participants remain more efficient when categorising faces by their occupation than by their name even when they have received extra practice of naming the faces.We conclude that the explanation best able to account for the data is that names are stored separately from other semantic information and can only be accessed after other identity specific information has been retrieved. However, we also argue that the demands we make of these explanations make it likely that no single theory will be able to account for all existing data. (shrink)

This article seeks to explain the variable implementation of gender mainstreaming as a `policy frame' over time and across various international organisations (I.O.s). In the years since the U.N. Fourth World Women's Conference in Beijing (1995),mainstreaming has been endorsed and adopted by a wide range of international organisations, and we compare the adoption and implementation of mainstreaming in four specific I.O.s: the World Bank, the United Nations Development Programme, the Organisation for Security and Cooperation in Europe, and the European Union. (...) The rhetorical acceptance of mainstreaming by various international organisations, however, obscures considerable variation in both the timing and the nature of the mainstreaming process within and among organisations. This variation, in turn, can be explained in terms of the categories of political opportunity, mobilising structures and strategic framing, which have been put forward by social movement theorists.

Silence has gained a prominent role in the field of psychotherapy because of its potential to facilitate a plethora of therapeutically beneficial processes within patients’ inner dynamics. This study examined the phenomenon from a conversation analytical perspective in order to investigate how silence emerges as an interactional accomplishment and how it attains interactional meaning by the speakers’ adjacent turns. We restricted our attention to one particular sequential context in which a patient’s turn comes to a point of possible completion and (...) receives a continuer by the therapist upon which a substantial silence follows. The data collection consisted of 74 instances of such post-continuer silences. The analysis revealed that silence can retroactively become part of a topic closure sequence, can become shaped as an intra-topic silence, and can be explicitly characterized as an activity in itself that is relevant for the therapy in process. Only in this last case, the absence of talk is actually treated as disruptive to the ongoing talk. Although silence is often seen as a therapeutic instrument that can be implemented intentionally and purposefully, our analysis demonstrated how it is co-constructed by speakers and indexically obtains meaning by adjacent turns of talk. In the ensuing turns, silence indeed shows to facilitate access to the patient’s subjective experience at unconscious levels. (shrink)

The unknown southern continent is perhaps one of the most puzzling aspects of Gerardus Mercator's otherwise strikingly modern cartography. This paper is an attempt to reconsider it in view of Renaissance cosmology and to outline two factors that led Mercator to engage with the mythical terra australis over decades: his socio-professional status as an artisan and the desire to be a philosopher, on the one hand, and the harsh business of mapmaking in the Low Countries on the other. The resulting (...) unknown southern continent was intimately connected to the classical tradition and geocentric cosmology but also to the specific social niche Mercator was trying to establish for himself.

Notwithstanding its obvious educational importance, the idea of an ethics of belief has been little explored by educational philosophers. The notion turns out to be more complex and to involve more difficulties than is usually supposed. Exploring these complexities and difficulties opens up many avenues of philosophical and educational inquiry. These in turn can enrich our reflections on contemporary educational developments and on ethical aspects of teaching. In particular they alert us to the need for educational theorists to give overdue (...) attention to the intellectual virtues. (shrink)

Compiled by disciples of Confucius in the centuries following his death in 479 B.C.E., _The Analects of Confucius_ is a collection of aphorisms and historical anecdotes embodying the basic values of the Confucian tradition: learning, morality, ritual decorum, and filial piety. Reflecting the model eras of Chinese antiquity, the Analects offers valuable insights into successful governance and the ideal organization of society. Filled with humor and sarcasm, it reads like a casual conversation between teacher and student, emphasizing the role of (...) the individual in the attainment of knowledge and the value of using historical events and people to illuminate moral and political concepts. Confucius's teachings focus on cultural and peaceful pursuits and the characteristics of benevolent and culturally distinguished government. He also discusses ancestor worship and other rites performed for the spirits of the dead. The single most influential philosophical work in all of Chinese history, _The Analects of Confucius_ has shaped the thought and customs of China and neighboring countries for centuries. Burton Watson's concise translation uses the pinyin romanization system and keeps explanatory notes to a minimum, yet his intimate knowledge of the Confucian tradition and precise attention to linguistic detail capture the original text's elegance, cogency, and wit.

Only by inhabiting Dao (the Way of Nature) and dwelling in its unity can humankind achieve true happiness and freedom, in both life and death. This is Daoist philosophy's central tenet, espoused by the person--or group of people--known as Zhuangzi (369?-286? BCE) in a text by the same name. To be free, individuals must discard rigid distinctions between right and wrong, and follow a course of action not motivated by gain or striving. When one ceases to judge events as good (...) or bad, man-made suffering disappears, and natural suffering is embraced as part of life. Zhuangzi elucidates this mystical philosophy through humor, parable, and anecdote, using non sequitur and even nonsense to illuminate truths beyond the boundaries of ordinary logic. Boldly imaginative and inventively written, the _Zhuangzi_ floats free of its historical period and society, addressing the spiritual nourishment of all people across time. One of the most justly celebrated texts of the Chinese tradition, the _Zhuangzi_ is read by thousands of English-language scholars each year, yet, until now, only in the Wade-Giles romanization. Burton Watson's conversion to pinyin in this book brings the text in line with how Chinese scholars, and an increasing number of other scholars, read it. (shrink)

Animal welfare science and ecology are both generally concerned with the lives of animals, however they differ in their objectives and scope; the former studies the welfare of animals considered ‘domestic’ and under the domain of humans, while the latter studies wild animals with respect to ecological processes. Each of these approaches addresses certain aspects of the lives of animals living in the world though neither, we argue, tells us important information about the welfare of wild animals. This paper argues (...) for the development of a new scientific discipline ‘welfare biology’ to address these issues and more, given the deficiencies of pre-existing life science disciplines to research the subject. Welfare biology is the study of the welfare of all living beings who have a welfare, with a value orientation toward promoting that welfare, regardless of the beings’ situation or relationship to humans and our activities.

The intent of this article is to outline, integrate, and interpret relevant scientific, economic, and social issues of rbST technology that have contributed to the acceptance dilemma for this product. The public is divided into social groups, each with its own set of criteria on which they base rbSTs acceptability. Criteria for the scientific community may best be described as physiological. However, for consumers, criteria may be more practical, or procedural, including human health, animal welfare, environmental concerns, and overproduction. Because (...) the business of dairy production depends on demand from the consuming public, the criteria for acceptance of rbST by producers largely reflects those of the consumers. Of necessity, producers are also critical of rbST from a business and animal improvement standpoint. Although this article demonstrates that rbST has met most physiological criteria for acceptance, the consuming public has treated the acceptance issue with forceful skepticism. The question this article addresses is, why? The authors comment that with rbST and other biotechnologies applied to agricultural animal production, it will be the responsibility of government health agencies, scientists, and manufacturers of the products to provide early, adequate, and honest public education. Attention to the concerns of the public may be the only means to prevent hysteria over this and future agricultural products of biotechnology and will, therefore, allow the public to form logical and thoughtful criteria assessments with respect to acceptance or rejection of each product.

“Scleroderma,” the rheumatologist said after examining my stiff swollen arms and legs. “Unfortunately, given your biomarkers, it’s likely to get worse before it gets better, but you never know.” She gave a quick rundown of what I might expect—rapidly progressive skin and joint tightening, GI symptoms, high likelihood of multi-organ involvement…. “Let’s hope for the best.” She paused, then asked if I had any questions.
