Face recognition depends upon the uniqueness of each human face. This is accomplished by the patterns formed by the unique relationship among face features. Unique face-patterns are produced by the intrusion of random factors into the process of biological growth and development. Processes are described which enable a unique face-pattern to be represented as a percept in the visual sensory system. The components of the face recognition system are analyzed (...) as is the manner in which the precept is connected through microcircuits to a memory file so that the history of a perceiver’s encounters with a familiar face enables the perceiver to access a memory store that is a record of the outcome of past encounters with the perceived. The importance of the face recognition system in enabling humans to individuate members the social group is discussed, as well as the importance of face recognition in the development of the individual’s social identity and ability to be a collaborative member of the social groups to which it belongs. The role of prosopagnosia—the inability to recognize familiar faces—in furthering an understanding of the face recognition system is examined, as is its importance in demonstrating the crucial nature of face recognition in human social functions. It is proposed that human face recognition is not a unique phenomenon but is an elaboration of processes existing in nonhuman primates as well as in lower animals. (shrink)

Interaction has been regarded as a key design component in online and distance learning. In this study, we convened a student-led, blended mode massive open online course study group to facilitate interactions for learning. Multiple data, including voice recordings, one-on-one interviews, video recordings, and artifacts were collected and analyzed to detect patterns of interaction in both face-to-face and online/Facebook settings, as well as student perceptions of the blended MOOC study group. Findings indicated that, overall, the blended mode (...) MOOC study group was helpful for promoting communication, providing help, resolving problems, and exchanging ideas and information among group members. Moreover, face-to-face meetings and online discussions both might have exerted their unique strengths and functions in different learning situations for different learners. We recommend future studies continue to explore the tenability of the blended mode MOOC study group in different contexts, subject areas, and age groups, as well as examining group dynamics and interactions that transform MOOC learning into interactive, motivating, and fulfilling journeys among study group members.

This article examines the relationships between disaster type and firms’ disaster responses. We draw on a unique dataset of 2,164 press releases related to the occurrence of 206 natural disasters over a 10-year period to analyze how firm responses are shaped by the type of disaster it faces. Firms play an increasingly important role in disaster response. We find that firms engage in more anticipatory responses when the type of disaster a firm faces exhibits even impact dispersion and high (...) expected recurrence, and provides substantial warning. Our study draws a relationship between physical geography, disaster type, and more anticipatory firm responses which can improve how firms and communities respond to the risks posed by different types of natural disasters. The article concludes by outlining an agenda for future research on firm responses to natural disasters. (shrink)

The COVID-19 pandemic affects all population segments and is especially detrimental to university students because social interaction is critical for a rewarding campus life and valuable learning experiences. In particular, with the suspension of in-person activities and the adoption of virtual teaching modalities, university students face drastic changes in their physical activities, academic careers, and mental health. Our study applies a machine learning approach to explore the gender differences among U.S. university students in response to the global pandemic. Leveraging (...) a proprietary survey dataset collected from 322 U.S. university students, we employ association rule mining techniques to identify and compare psychological, cognitive, and behavioral patterns among male and female participants. To formulate our task under the conventional ARM framework, we model each unique question-answer pair of the survey questionnaire as a market basket item. Consequently, each participant's survey report is analogous to a customer's transaction on a collection of items. Our findings suggest that significant differences exist between the two gender groups in psychological distress and coping strategies. In addition, the two groups exhibit minor differences in cognitive patterns and consistent preventive behaviors. The identified gender differences could help professional institutions to facilitate customized advising or counseling for males and females in periods of unprecedented challenges. (shrink)

BackgroundCurrently, most people who might need mental health care services do not receive them due to a number of reasons. Many of these reasons can be overcome by telepsychology, in other words, the use of ICT technologies for therapy ; given that it facilitates access to specialized interventions. In fact, telepsychology is currently offered as an active service in many psychotherapy centers. However, its usage, how it is perceived, and who uses it are still largely unknown.ObjectiveThe aim of this study (...) was to determine if any pattern exists in the usage of telepsychology and face-to-face psychology, to clarify people’s perception of telepsychology in terms of the advantages, barriers and efficacy of online psychotherapy, and to examine usage patterns in terms of individual characteristics and identify patients’ profiles.MethodsAn online survey was conducted on a convenience sample of 514 subjects recluted by using an online advertisement. The inclusion criteria were: to be older than 18 years old and to answer completely the questionnaire. Cluster analysis, ANOVAs, and discriminant analysis were performed to test our research objectives.ResultsThree usage clusters were found: face-to-face psychotherapy ; non-therapy ; and combined face-to-face psychotherapy and telepsychology. In addition, the perception of telepsychology varied among usage clusters, but a common perception emerged about the main telepsychology advantages, barriers and efficacy. Finally, the results showed that personal characteristics differentiated people in each of these clusters.ConclusionThe most common form of access to psychotherapy is the face-to-face form but the second way of delivery was a combination between face to face and online psychotherapy. People who combine face to face with online psychotherapy perceives this last as more efficient and with less barriers to access. Finally, some characteristic as eHealth experience and sociodemographic variables can help to identify people that will attend telepsychology initiatives. These clusters provide insight into opportunities for face-to-face and online patient engagement strategies. (shrink)

The embryonic vertebrate face is composed of similarly sized buds of neural crest‐derived mesenchyme encased in epithelium. These buds or facial prominences grow and fuse together to give the postnatal morphology characteristic of each species. Here we review the role of neural crest cells and foregut endoderm in differentiating facial features. We relate the developing facial prominences to the skeletal structure of the face and review the signals and genes that have been shown to play an important role (...) in facial morphogenesis. We also examine two experiments one at the genetic level and one at the signal level in which transformation of facial prominences and subsequent change of jaw identity was induced. We propose that signals such as retinoids and BMPs and downstream transcription factors such as Distal‐less related genes specify jaw identity.

Impairments in emotional face processing are demonstrated by individuals with neurodevelopmental disorders, including autism spectrum disorder and attention-deficit/hyperactivity disorder, which is associated with altered emotion processing networks. Despite accumulating evidence of high rates of diagnostic overlap and shared symptoms between ASD and ADHD, functional connectivity underpinning emotion processing across these two neurodevelopmental disorders, compared to typical developing peers, has rarely been examined. The current study used magnetoencephalography to investigate whole-brain functional connectivity during the presentation of happy and angry faces (...) in 258 children, including ASD, ADHD and typically developing groups to determine possible differences in emotion processing. Data-driven clustering was also applied to determine whether the patterns of connectivity differed among diagnostic groups. We found reduced functional connectivity in the beta band in ASD compared to TD, and a further reduction in the ADHD group compared to the ASD and the TD groups, across emotions. A group-by-emotion interaction in the gamma frequency band was also observed. Greater connectivity to happy compared to angry faces was found in the ADHD and TD groups, while the opposite pattern was seen in ASD. Data-driven subgrouping identified two distinct subgroups: NDD-dominant and TD-dominant; these subgroups demonstrated emotion- and frequency-specific differences in connectivity. Atypicalities in specific brain networks were strongly correlated with the severity of diagnosis-specific symptoms. Functional connectivity strength in the beta network was negatively correlated with difficulties in attention; in the gamma network, functional connectivity strength to happy faces was positively correlated with adaptive behavioural functioning, but in contrast, negatively correlated to angry faces. Our findings establish atypical frequency- and emotion-specific patterns of functional connectivity between NDD and TD children. Data-driven clustering further highlights a high degree of comorbidity and symptom overlap between the ASD and ADHD children. (shrink)

At its proper and most radical, humanistic inquiry is about problems that do not have ready solutions. If this fundamental feature had been accepted, debates about the humanities in recent years might have taken a different kind of turn, whereby, instead of appending new and ever more purposeful modifiers to the word humanities--the digital, the environmental, the neuro, the medical, the public--the ways in which humanistic modes of intellectual labor operate could have assumed a more central focus. This would not (...) have to mean adopting a conservative or conservatively disciplinary stance toward the humanities. Rather, it would demonstrate the ways in which humanistic inquiry approaches intellectual problems conceptually, methodologically, and practically, without necessarily seeking to legitimize the relevance of its undertakings by way of social utility and consensus.This possibility of reimagining humanistic study is the basic assumption and orientation of this book. Many books make use of Foucault's theories, but few use his work to reflect on the conundrums, dead ends, and potentialities of humanistic inquiry in the current Western academy. By juxtaposing debates about literary study, visibilities and invisibilities, sound/voice/listening, race/racism, and self- governance/entrepreneurship in a unique constellation against what Chow polemicizes as the moral instrumentalization of knowledge, A Face Drawn in Sand is intended as an intervention in some of the most pressing issues facing humanistic study today: how to process and analyze texts; how to form and sustain arguments; how to reconceptualize familiar problems through lesser known as well as very well known sources. Above all, how not to have the answers before the questions. (shrink)

To desire something is a condition familiar to everyone. It is uncontroversial that desiring has something to do with motivation, something to do with pleasure, and something to do with reward. Call these "the three faces of desire." The standard philosophical theory at present holds that the motivational face of desire presents its unique essence--to desire a state of affairs is to be disposed to act so as to bring it about. A familiar but less standard account holds (...) the hedonic face of desire to reveal to true nature of desire. In this view, to desire something is to tend to pleasure if it seems that the desired state of affairs has been achieved, or displeasure if it seems otherwise, thus tying desire to feelings instead of actions. In Three Faces of Desire, Schroeder goes beyond actions and feelings to advance a novel and controversial theory of desire that puts the focus on desire's neglected face, reward. Informed by contemporary science as much as by the philosophical tradition, Three Faces of Desire discusses recent scientific discoveries that tell us much about the way that actions and feelings are produced in the brain. In particular, recent experiments reveal that a distinctive system is responsible for promoting action, on the one hand, and causing feelings of pleasure and displeasure, on the other. This system, the brain's reward system, is the causal origin of both action and feeling, and is the key to understanding the nature of desire. (shrink)

The question of “Are faces special?” has essentially referred to whether there are unique visual mechanisms for processing identity-related information in faces as compared to other objects. Faces provide unique information about expression, gaze direction, identity, and visual cues to speech. In the literature, however, the debate about whether “faces are special” has referred to the specific question of whether there are special visual processing mechanisms unique to faces, presumably deriving from the social importance of faces and (...) developed either across the course of evolution or the course of childhood. This article provides historical background to the question and presents key theoretical findings and key methodological findings. It reviews literature on an evolved face representation, including studies of newborns, face-deprived monkeys and twins; on configural behavioral processing in object experts; and on neural processing in object novices and object experts including single-unit recording, fMRI, ERPs, TMS, and neuropsychological studies.

The critical issues facing the human community population growth, sustained development, threats to the environment, the arms race, the ethical/philosophical challenges in light of advances in science and technology, and our very survival as a species require a multidisciplinary approach grounded in a clear understanding of human behavior. Fifty-one scholars from 11 countries representing 19 disciplines met at Delphi, Greece, to discuss and debate why we do what we do to ourselves and our world. Out of this vigorous exchange emerged (...) the Delphi Society for long-term study of patterns of human behavior. This book offers a unique international perspective on global human problems.

Biometrics is essentially a pattern recognition system that recognizes an individual using their unique anatomical or behavioral patterns such as face, fingerprint, iris, signature etc. Recent researches have shown that many biometric traits are vulnerable to spoof attacks. Moreover, recent works showed that, contrary to a common belief, multimodal biometric systems in parallel fusion mode can be intruded even if only one trait is spoofed. However, most of the results were obtained using simulated spoof attacks, under the (...) assumption that the spoofed and genuine samples are indistinguishable, which may not be true for all biometric traits. In addition, so far vulnerability of multimodal biometric systems in serial fusion mode against spoof attacks has not been investigated. These issues raise a demand to investigate the robustness of multimodal systems under realistic spoof attacks. In this paper, we empirically investigate the performance of serial and parallel biometric fusion modes under realistic spoof attacks. Preliminary empirical results on real biometric systems made up of face, fingerprint and iris confirm that multimodal biometric systems in both fusion modes are not intrinsically robust against spoof attacks as believed so far. In particular, multimodal biometric systems in serial fusion mode can be even less robust than systems in parallel mode. We also experimentally found that incorporating the biometric sample quality in biometric fusion increases the robustness of the multimodal systems against spoof attacks. In the end, we study the trade-off between performance and robustness of the biometric systems under spoof attacks. (shrink)

Various authors have recently argued that you cannot rationally stick to your belief in the face of known disagreement with an epistemic peer, that is, a person you take to have the same evidence and judgmental skills as you do. For, they claim, because there is but one rational response to any body of evidence, a disagreement with an epistemic peer indicates that at least one of you is not responding rationally to the evidence. Given that you take your (...) peer to have the same judgmental skills as you do, and thus regard her to be equally good at assessing the evidence as you are, you will have as much reason for thinking that it is you who is not responding rationally to the evidence as for thinking that it is her. You thus have reason for thinking that your belief on the disputed matter is not a rational response to the evidence. Hence, you cannot rationally stick to your belief. (shrink)

The article concentrates on the analyses of the content characteristics of the users’ activity patterns functioning in the media ecosystem. Media ecosystem is viewed by the author as information environment of a modern individual which dialectically connects the users’ media activity practices as well as the institutional conditions of their realization. The author refers to such key practices of users’ activity in the media ecosystem as media consumption and media production, notably an important factor of such practices realization are (...) definite patterns and normals, which are the behavior models articulates in the media ecosystem environment. It is shown that these patterns and normals can be localized in such media sources as the news in mass media, fiction texts and program manifestations, technological regulations (exploitation rules, access procedures etc.), society knowledge (etiquette, etc.) of the network community. On the basis of the author’s sociological research, carried out using the content analyses (N=300) method (different types of media sources in the modern media ecosystem were studied), peculiarities of actual patterns and normals of users’ activity in media ecosystem are analyzed. The author shows how the imperative character of the patterns and normals declared reveals in a number of characteristics that are the criteria of the analyses. As a result of the research it was found out that the level of imperativeness of articulated patterns and normals is defined not only by their immediate localization (the type of media source where they were placed) but also by the referentiality of these normals to the unique experience of the users and the prevailing types of media activity.

James Lovelock n'a pas eu de chance avec l'hypothèse Gaïa. En nommant par ce vieux mythe grec le système fragile et complexe par lequel les phénomènes vivants modifient la Terre, on a cru qu'il parlait d'un organisme unique, d'un thermostat géant, voire d'une Providence divine. Rien n'était plus éloigné de sa tentative. Gaïa n'est pas le Globe, n'est pas la Terre-Mère, n'est pas une déesse païenne, mais elle n'est pas non plus la Nature, telle qu'on l'imagine depuis le XVIIe (...) siècle, cette Nature qui sert de pendant à la subjectivité humaine. La Nature constituait l'arrière-plan de nos actions. Or, à cause des effets imprévus de l'histoire humaine, ce que nous regroupions sous le nom de Nature quitte l'arrière-plan et monte sur scène. L'air, les océans, les glaciers, le climat, les sols, tout ce que nous avons rendu instable, interagit avec nous. Nous sommes entrés dans la géohistoire. C'est l'époque de l'Anthropocène. Avec le risque d'une guerre de tous contre tous. L'ancienne Nature disparaît et laisse la place à un être dont il est difficile de prévoir les manifestations. Cet être, loin d'être stable et rassurant, semble constitué d'un ensemble de boucles de rétroactions en perpétuel bouleversement. Gaïa est le nom qui lui convient le mieux. En explorant les mille figures de Gaïa, on peut déplier tout ce que la notion de Nature avait confondu : une éthique, une politique, une étrange conception des sciences et, surtout, une économie et même une théologie.

Physicist David Bohm and biochemist Ilya Prigogine began a dialogue that implied a deep, structuring, primordial harmony within life. In classical Chinese this harmony is referred to as Li, which also designates the elegant, natural pattern found in jade.

Insights from Bohm, Prigogine, and others on releasing outmoded thinking (...) and actions are integrated with contemplative traditions, Eastern and Western philosophy, and pragmatic strategy making.

The Aymara of the Andes use absolute (cardinal) frames of reference for describing the relative position of ordinary objects. However, rather than encoding them in available absolute lexemes, they do it in lexemes that are intrinsic to the body: nayra (“front”) and qhipa (“back”), denoting east and west, respectively. Why? We use different but complementary ethnographic methods to investigate the nature of this encoding: (a) linguistic expressions and speech–gesture co-production, (b) linguistic patterns in the distinct regional Spanish-based variety Castellano (...) Andino (CA), (c) metaphorical extensions of CA’s spatial patterns to temporal ones, and (d) layouts of traditional houses. Findings indicate that, following fundamental principles of Aymara cosmology, people, objects, and land—as a whole—are conceived as having an implicit canonical orientation facing east, a primary landmark determined by the sunrise. The above bodily based lexicalizations are thus linguistic manifestations of a broader macro-cultural worldview and its psycho-cognitive reality. (shrink)

Climatologists have a unique role in providing various stakeholders and public data users with weather and climate information. In the north central region of the United States, farmers, the agricultural sector, and policy makers are important audiences for climate science. As local and global climate conditions continue to shift and affect agricultural productivity, it is useful to understand how climatologists view their role as scientists, and how this influences their communication of climate science to agricultural stakeholders. In this study, (...) data from interviews and surveys of state and extension climatologists in the NCR are analyzed to identify perceived roles and responsibilities as scientists and communicators. Pielke’s framework of the idealized roles of scientists and their communication patterns are used to develop a typology of climate science communication. Findings reveal that more than half of climatologists perceive their role to provide information as pure scientists, while some engage in an arbiter role when requested. Fewer climatologists view their role as not only producing new knowledge, but also relating it to society and providing an expanded variety of alternative applications. Climatologists who perceive their role as simply providing information and letting data users interpret its application are missing an opportunity to reduce the gap between what scientists know and farmers believe. This suggests that if climatologists would frame their climate science message in terms of agricultural impacts, hazard mitigation and risk management alternatives they could help the agricultural sector adapt to and mitigate environmental risks from a changing climate.

Both individuals with diagnosed with Autism Spectrum Disorder and individuals high in psychopathic traits show reduced susceptibility to contagious yawning; that is, yawning after seeing or hearing another person yawn. Yet it is unclear whether the same underlying processes are responsible for the relationship between reduced contagion and these very different types of clinical traits. College Students watched videos of individuals yawning or scratching while their eye movements were tracked. They completed the Interpersonal Reactivity Index, the Autism-Spectrum Quotient, the Psychopathy (...) Personality Inventory-Revised, and the Adolescent and Adult Sensory Processing Disorder Checklist. Both psychopathic traits and autistic traits showed an inverse relationship to contagious yawning, consistent with previous research. However, the relationship between autistic traits and contagious yawning was moderated by eye gaze. Furthermore, participants high in autistic traits showed typical levels of contagious itching whereas adults high in psychopathic traits showed diminished itch contagion. Finally, only psychopathic traits were associated with lower overall levels of empathy. The findings imply that the underlying processes contributing to the disruptions in contagious yawning amongst individuals high in autistic vs. psychopathic traits are distinct. In contrast to adults high in psychopathic traits, diminished contagion may appear amongst people with high levels of autistic traits secondary to diminished attention to the faces of others, and in the absence of a background deficit in emotional empathy.

What is morality? In Practical Expressivism, I argue that morality is a purely natural interpersonal co-ordination device, whereby human beings express their attitudes in order to influence the attitudes and actions of others. -/- The ultimate goal of these expressions is to find acceptable ways of living together. This 'expressivist' model for understanding morality faces well-known challenges concerning 'saving the appearances' of morality, because morality presents itself to us as a practice of objective discovery, not pure expression. -/- This book (...) demonstrates how a properly developed expressivist view can overcome this objection, by showing that even if moral practice is fundamentally expressive, it can still come to possess those features that make it appear objective (features such as talk and thought of moral disagreement, truth and belief, and the applicability of logical notions to moral sentences). The key to this development is to emphasise the unique and intricate practical role that morality plays in our lives. Practical expressivism is also practical in the further sense that it provides repeatable patterns that expressivists can deploy in coming to understand the apparently objective features of morality.

Comparative psychology is a strongly interdisciplinary field that shares many of its experimental methods and observational techniques with ethology and developmental psychology. The great variety of theories that comparative psychology evokes to explain behavior generates a wide array of exciting and potentially fruitful accounts, but is also problematic. It increases the risk of error in the forms of inconsistent background assumptions, conceptual misunderstandings, unfalsifiable hypotheses and incoherent explanations, which in spite of perhaps being minor by themselves will impede scientific progress (...) in the long run. Moreover, similarly to psychology at large, comparative psychology tends to emphasize empirical investigations to the disadvantage of the analysis and development of theories and concepts. Consequently, disagreements that have their roots elsewhere than in methodology and experimental design do not receive sufficient attention. Furthermore, while evidence about biological evolution is notoriously hard to find, the methodology for comparing the capacities of different species is under continuous development. This forces comparative psychology to rely on the adequacy of the theoretical and conceptual framework to a greater extent than normally in the empirical sciences. In view of investigating the background of the problems that contemporary comparative psychology is facing, the present chapter examines central parts of the methodology and explanatory framework of comparative psychology as well as its global objective.

This paper argues for extreme rational permissivism—the view that agents with identical evidence can rationally believe contradictory hypotheses—and a mild version of steadfastness. Agents can rationally come to different conclusions on the basis of the same evidence because their way of weighing the theoretic virtues may differ substantially. Nevertheless, in the face of disagreement, agents face considerable pressure to reduce their confidence. Indeed, I argue that agents often ought to reduce their confidence in the higher-order propositions that they (...) know or rationally believe disputed content. I argue, however, that when the subject matter is difficult, there is more flexibility for agents to simultaneously believe that p while withholding belief about whether such belief is rational or known. This allows for modest steadfastness on hard questions in, e.g., philosophy and religion. (shrink)

A notation for an ordinal using patterns of resemblance is based on choosing an isominimal set of ordinals containing the given ordinal. There are many choices for this set meaning that notations are far from unique. We establish that among all such isominimal sets there is one which is smallest under inclusion thus providing an appropriate notion of normal form notation in this context. In addition, we calculate the elements of this isominimal set using standard notations based on (...) collapsing functions. This provides a capstone to the results in [2, 6, 8, 9, 7], using further refinement of ordinal arithmetic developed in [8] which then both allows for a simple characterization of normal forms for patterns of order one and will play a key role in the arithmetical analysis of pure patterns of order two, [5].
