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)

Much of the mathematics with which Felix Klein and Sophus Lie are now associated (Klein’s Erlangen Program and Lie’s theory of transformation groups) is rooted in ideas they developed in their early work: the consideration of geometric objects or properties preserved by systems of transformations. As early as 1870, Lie studied particular examples of what he later called contact transformations, which preserve tangency and which came to play a crucial role in his systematic study of transformation groups and differential equations. (...) This note examines Klein’s efforts in the 1870s to interpret contact transformations in terms of connexes and traces that interpretation (which included a false assumption) over the decades that follow. The analysis passes from Klein’s letters to Lie through Lindemann’s edition of Clebsch’s lectures on geometry in 1876, Lie’s criticism of it in his treatise on transformation groups in 1893, and the careful development of that interpretation by Dohmen, a student of Engel, in his 1905 dissertation. The now-obscure notion of connexes and its relation to Lie’s line elements and surface elements are discussed here in some detail. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 9.1 (2002) 93-96 [Access article in PDF] Phenomenological Methods in Psychiatry:A Necessary First Step M. Gupta and L. Rex Kay Keywords: behavior, empathy, human science, methodology, natural science, phenomenology. WE ARE GRATEFUL to the journal for prviding the opportunity for exchange and discussion of some of the themes raised in our paper, "The impact of phenomenology on North American psychiatric assessment" and we are pleased (...) to be able to reply to the two excellent commentaries by McMillan and Morley. Both McMillan and Morley question the prospect of employing phenomenology and its methods in psychiatric assessment, and in psychiatric practice more generally. McMillan questions the utility of such a step, and Morley is pessimistic about its feasibility. We shall address each author's concerns in turn.Initially, let us restate the aims of our paper to contextualize our arguments and those made in the commentaries. First, we sought an understanding of what is meant by North American psychiatrists, working within the DSM framework, when they refer to the phenomenological approach to psychiatric assessment. To elucidate this meaning, we compared the contemporary North American usage to a small number of definitions of phenomenology, particularly those definitions that were, and are now, applied to clinical psychiatric work. Contrary to McMillan's suggestion, we did not intend to state definitively what should or should not count as phenomenological, but rather to compare North American psychiatric assessment to what typically has counted as phenomenological. Second, we sought to examine phenomenology's influence on North American psychiatric practice, particularly psychotherapy.Morley argues that such influences usually exemplify the inappropriate appending of phenomenology to psychiatric practice rather than true integration of different paradigms. Although we do not disagree with this general contention, we will argue that the deployment of phenomenological methods in psychiatric assessment is a necessary first step toward the kind of integration he proposes.McMillan makes two related but unintegrated points. First, he argues that objective, behavioral data are phenomenological, according to his broad definition of the term. Second, he proposes that, if the behavioral and the phenomenological are different, we are better off staying with the behavioral when it comes to psychiatric nosology. Let us consider these two points in succession.McMillan seeks to broaden Jasper's definition of phenomenology to include objective observations [End Page 93] as phenomenological. To this end, he distinguishes methods from aims. He summarizes Jasper's definition of phenomenology as "an empirical method for investigating 'individual psychic experience (p 55)" and claims that this is a statement of aim or objectives. He then urges us to "consider the merits of different phenomenological methodologies in terms of their success in achieving this objective" whether or not they utilize "all the methods" of phenomenology. This is much like saying that if we treat waving one's hand as a method for greeting someone, we are then free to treat the objective of the wave as one of greeting someone, and then say that anything that serves as a greeting is, by definition, a "wave." Whatever else McMillan's objective observations are, he has not convinced us that they are phenomenological, anymore than we are likely to convince you that a kiss on the lips is really just a wave.Nonetheless, it is worthwhile seeing what McMillan does with this argument. He tells us that we can "read the first-person experience from behavior in a fairly accurate and informative way." He uses the example of a father gazing at his young child and notes that it is not unreasonable to infer that he is experiencing loving and nurturing feelings. It is, indeed, not unreasonable to draw such an inference. But it is far more reasonable to infer that the father is experiencing a cacophony of feelings, including, but not limited to, love, concern, anxiety, pride, envy, hope, and sadness (Stern 1995, 18-58). If we are able to distinguish which of these feelings is dominant at any given moment—which we are—and if we are also able to track subtle shifts in such feelings... (shrink)

North American psychiatric literature describes the current method of psychiatric diagnostic assessment as "phenomenological"; however, it is unclear what phenomenology 1 means in this context. This paper investigates the meaning and impact of some of the major philosophical and psychiatric definitions of phenomenology on contemporary psychiatric assessment. Employing a comparative analysis of selected definitions of phenomenology, this paper argues that North American psychiatric assessment does not reflect any of these definitions of phenomenology. Instead, within the context of psychiatric assessment, phenomenology (...) has taken on an idiosyncratic, clinical meaning of signs and symptoms. However, this does not mean that phenomenology has had no impact on North American psychiatry. This paper contends that phenomenology has made contributions to psychiatry, particularly in the area of psychotherapy and especially in self-psychological psychotherapy. The importance of the concept of empathy within psychotherapy is evidence of the continuing influence of philosophical phenomenology on psychiatry. This paper concludes that phenomenology can provide an important complementary perspective to the dominant methods of North American psychiatric practice. (shrink)

As leadership discourses in higher education are increasingly being mediated online, texts previously reserved for staff are now being made available in the public domain. As such, these texts become accessible for study, critique and evaluation. Additionally, discourses previously confined to the written domain are now increasingly multimodal. Thus, an approach is required that is capable of relating detailed, complex multimodal discourse analyses to broader sociocultural perspectives to account for the complex meaning-making practices that operate in online leadership discourses. For (...) this purpose, a digital multimodal discourse approach is proposed and illustrated via a small-scale case study of the online leadership discourse of an Australian university. The analysis of two short video texts demonstrates how a digital multimodal discourse perspective facilitates the identification of key multimodal systems used for meaning-making in online communication, how meaning arises through combinations of semiotic choices, and how the results of multimodal discourse analysis using digital technology can reveal larger sociocultural patterns – in this case, divergent leadership styles and approaches as reflected in online discourse, at a time of immense change within the higher education sector.

International education is impacted by multiple discourses, in particular the discourse of university as an educational institution responsible for producing and curating knowledge for the public good, pursuing truth and transforming student life, and the neoliberal marketing discourse which portrays the university as a business organization providing a service for international students as customers/consumers. Following a multimodal discourse analytic perspective, this study examines ‘Why Choose’ webpages of one British and two Australian universities to identify how the apparently conflicting higher education (...) and neoliberal marketing discourses are managed in the interdiscursive space using language, images and videos. The results reveal that ‘Why Choose’ webpages are hybrid texts where the discourse of higher education is upheld in relation to the neoliberal marketing discourse through multimodal strategies of accentuation, infusion and progression. The study argues for the necessity of undertaking a multimodal discourse approach to understand how various positions are negotiated interdiscursively in online media. (shrink)

This study takes a systemic functional multimodal social semiotic approach to the analysis and discussion of image and text relations in two sets of data. First, patterns of contextualisation of images and text in the online magazines Dabiq and Rumiyah produced by the Islamic extremist organisation which refers to itself as Islamic State are examined. The second data set consists of a sample of texts from Western online news and blog sites which include recontextualisations of images found in the first (...) data set. A sample of examples of the use and re-use of images is discussed in order to identify patterns of similarity and difference when images and text are recontextualised. It is argued that the ISIS material tends to foreground the interpersonal metafunction in combination with the textual metafunction, while the other data set tends to foreground the ideational metafunction. These inferences indicate that further exploration of a larger data set is worth pursuing. Such studies would provide deeper insights helping to distinguish between online material which supports terrorism and that which opposes it, as well as facilitating the further development of multimodal social semiotic approaches to image and text relations.

This article examines emergency ambulance calls made by lay callers for patients found to be in cardiac arrest when the paramedics arrived. Using conversation analysis, we explored the trajectories of calls in which the caller, before being asked by the call-taker, said why they were calling, that is, calls in which callers pre-empted a reason-for-the-call. Caller pre-emption can be disruptive when call-takers first need to obtain an address and telephone number. Pre-emptions have further implications when call-takers reach the stage when (...) they are required to deliver the scripted turn ‘tell me exactly what happened’. When there has been a pre-emption earlier on, callers tend to treat the scripted turn as a request for more information and may not repeat their reason-for-the-call. This can occasion delays and important information can be lost. We identified an effective alternative strategy used by some call-takers, pre-emption repeat, which callers treat as a request for confirmation. (shrink)

In this perspectives article, we maintain that the current local to global sustainable development predicaments we face are the result of humanity's impact on the Earth System (ES)—that is to say, on the very systemic fabric of the ES (i.e., its functioning and configuration), combined with an insufficiently coherent application of sustainable development policy to address and resolve this systemic problem. In response to what is an urgent crisis, we propose four foundational guiding principles, which we contend provide an overarching (...) framing that, if implemented, would offer an approach to steer global sustainable development policy in a manner that would be to the benefit of the ES and the securing of a flourishing future for all. Our principles are applicable at the levels from a local business ecosystem, national‐regional networks, to global policy. (shrink)

In this essay we discuss a class of apparently metaphorical idioms, exemplified by “fine as frog's hair,” that do not afford any obvious interpretation, and appear to have originated, at least in part, in language play. We review recent trends in both play theory and metaphor theory, and show that a playful approach to language is often an important element in the use and understanding of metaphors (and idioms generally), even when metaphors can be readily interpreted by means of a (...) vehicle-to-topic mapping. Based on this evidence we call for a more deliberate inclusion of language play in metaphor theory and analysis. (shrink)

Until recently, retention of introns in mature mRNAs has been regarded as a consequence of mis‐splicing. Intron‐retaining transcripts are thought to be non‐functional because they are readily degraded by nonsense‐mediated decay. However, recent advances in next‐generation sequencing technologies have enabled the detection of numerous transcripts that retain introns. As we review herein, intron‐retaining mRNAs play an essential conserved role in normal physiology and an emergent role in diverse diseases. Intron retention should no longer be overlooked as a key mechanism that (...) independently reduces gene expression in normal biology. Exploring its contribution to the development and/or maintenance of diseases is of increasing importance. (shrink)

Conceptual integration theory (Fauconnier & Turner, 1998, 2002) is re-examined in the light of recent criticisms (e.g., Gibbs, 2000, 2001). It is argued that the assumption of four independent "cognitive spaces" enters the model primarily as an entailment of the "space," "blending," and "construction" metaphors, leads to unnecessary ambiguity, and works against statement of the theory in a form that supports derivation of testable hypotheses. Several examples from Fauconnier and Turner (2002) are analyzed to show that they can be interpreted (...) more simply, without need of four separate "spaces." Suggestions are made for reformulating conceptual integration theory without the problematic metaphors. (shrink)

In the 1950s and 1960s Freudian theory was deemed to be a vital part of the sociological tradition, but since then it has fallen from favor, largely because of the simplifications and misinterpretations both by Freud's sociological critics and by his supporters. Chief among such misunderstandings is the tendency to view Freud's social theory as a variant of that of Hobbes, in which a selfish and asocial human nature is made social through the imposition of external constraints; these constraints, as (...) Durkheim stated, eventually are "internalized" into the personalities of social beings. Against such a claim this paper argues that Freud's views differ profoundly from those of Hobbes and that the myth of the Hobbesian Freud has so distorted Freud's most fundamental concepts that their social theoretical significance has been largely obscured.

The way the brain, body, and mind interact with social structure to shape communication has so far not received the attention it deserves. This book addresses this gap by providing a novel account of communication as a social, biological and neurological force. Combining theories from communication studies and psycholinguistics, and drawing on biological and evolutionary perspectives, it shows how communication is inherently both biological and social, and that language and the neural systems that support it have evolved in response to (...) a complex social environment. It introduces a clear set of terms based on current research, and illustrates key concepts using real-life examples from everyday conversation - speaking to a number of current debates around the evolutionary and biological basis of language, and the relationship between language, cognition, and environment. Thought provoking and engaging, it will change the way we think about the relationship between communication and cognition. (shrink)

Recent work has shown that many problematic aspects of metaphor use and comprehension can be resolved through an account that includes both relevance and perceptual simulation. It has also been shown that metaphors often imply stories, and that stories are often metaphorical. Previous research on narratives has focused primarily on stories that appear either in formal literature or in structured interviews; this essay focuses on stories that occur as an integral part of conversation. It extends recent work on metaphor comprehension (...) to show how use and comprehension of stories in natural, informal conversations can be usefully analyzed in terms of perceptual simulations. Conversely, it extends previous work on storytelling to reveal the metaphorical element in many stories, and to emphasize the social (bonding through shared enjoyment) as well as informative and persuasive functions of storytelling.

Halliday’s theory of grammatical metaphor has been quite influential among scholars who study structural approaches to language but has received little attention among researchers in cognitive linguistics. In this paper we summarize the aspects of Halliday’s approach that are most relevant to cognitive linguists, and show how key aspects of grammatical metaphor are related to the analysis of lexical and conceptual metaphors. Using an example of scientific writing analyzed by Halliday as well as examples from discourse previously subjected to conceptual (...) metaphor analysis, we show how the two approaches might usefully be combined to yield new insights in the analysis of naturally occurring discourse.

Do cultural models facilitate particular ways of perceiving interactions in nature? We explore variability in folkecological principles of reasoning about interspecies interactions. In two studies, Indigenous Panamanian Ngöbe and U.S. participants interpreted an illustrated, wordless nonfiction book about the hunting relationship between a coyote and badger. Across both studies, the majority of Ngöbe interpreted the hunting relationship as cooperative and the majority of U.S. participants as competitive. Study 2 showed that this pattern may reflect different beliefs about, and perhaps different (...) awareness of, plausible interspecies interactions. Further probes suggest that these models of ecological interaction correlate with recognition of social agency in nonhuman animals. We interpret our results in terms of cultural models of nature and nonhuman agency. (shrink)
