Chaotic itinerancy is useful for illustrating transitions in attractor dynamics seen in the olfactory system. Cantor coding is a good model for information processing, but so far it lacks perceptual proof. The theories presented provide a large step toward bridging the use of chaos as an interpretive tool and hard examination of chaotic neural activity during perception.

This research addresses the question of whether men and women in sales differ in their ethical attitudes and decision making. The study asked 209 subjects to respond to 20 ethical scenarios, half of which were "relational" and half "non-relational." The study concludes (1) that there are significant ethical differences between the sexes in situations that involve relational issues, but not in non-relational situations, and (2) that gender-based ethical differences change with age and years of experience. The implications of these finding (...) for sales organizations are discussed. (shrink)

“You Have Seen Their Faces”: Gisèle Freund, Walter Benjamin and Margaret Bourke-White as Headhunters of the Thirties -/- Abstract This paper concentrates on one work by each of three authors: Walter Benjamin’s Deutsche Menschen (Germans), an anthology of twenty-five 18th and 19th century German personal letters; Margaret Bourke-White and Erskine Caldwell’s You Have Seen Their Faces; and Gisèle Freund’s collection of photographic portraits of writers and artists, compiled between 1936 and 1939. The purpose of this paper is to compare the (...) politics of representation of these three figures and to examine the challenge they addressed to the dominant iconography of the 1930s. At the heart of each one’s work was a desire to bring about a shift in contemporary cultural politics by reimagining the body politic. Benjamin’s and Freund’s aim was to displace the monumentalizing, distancing, ‘heroic’ forms of fascist art and writing. They construct and project an intimate, or ‘domestic’ image of humanism as a form of social practice, past and present. Bourke-White’s aim was to bring to visibility an America concealed beneath the glossy homogenized images of white American advertising. All three authors aligned themselves with a documentary tradition that believed that representation should function as a constructed record of the traces of lived experience. Driven by a need to expose the other side’s deliberate falsifications of experience, they saw their own constructed fictions as ways of ‘documenting,’ and then perhaps transforming, an experiential world of ‘facts,’ bodies, and ‘truths.’ -/- Working Paper 3:15 European Society and Culture Research Group.

Colorado has consistently had one of the highest rates of suicide in the United States, and El Paso County has the highest number of suicide and firearm-related suicide deaths within the state. Community-based solutions like those of the Suicide Prevention Collaborative of El Paso County may be more effective in preventing suicide as they are specific to local issues, sensitive to local culture, and informed by local data, community members, and stakeholders.

In team-based tasks, successful communication and mutual understanding are essential to facilitate team coordination and performance. It is well-established that an important component of human conversation is the maintenance of common ground. Maintaining common ground has a number of associated processes in which conversational participants engage. Many of these processes are lacking in current synthetic teammates, and it is unknown to what extent this lack of capabilities affects their ability to contribute during team-based tasks. We focused our research on how (...) teams package information within a conversation, by which we mean specifically whether information is explicitly mentioned or implied, and how multiple pieces of information are ordered both within single communications and across multiple communications. We re-analyzed data collected from a simulated remotely-piloted aerial system task in which team members had to specify speed, altitude, and radius restrictions. The data came from three experiments: the “speech” experiment, the “text” experiment, and the “evaluation” experiment. We asked first whether teams settled on a specific routine for communicating the speed, altitude, and radius restrictions, and whether this process was different if the teams communicated in speech compared to text. We then asked how receiving special communication instructions in the evaluation experiment impacted the way the human teammates package information. We found that teams communicating in either speech or text tended to use a particular order for mentioning the speed, altitude, and radius. Different teams also chose different orders from one another. The teams in the evaluation experiment, however, showed unnaturally little variability in their information ordering and were also more likely to explicitly mention all restrictions even when they did not apply. Teams in the speech and text experiments were more likely to leave unnecessary restrictions unmentioned, and were also more likely to convey the restrictions across multiple communications. The option to converge on different packaging routines may have contributed to improved performance in the text experiment compared some of the conditions in the evaluation experiment. (shrink)

Cells express many proteins that bind to laminin, the major adhesive component of basement membranes. Some of these, specifically integrins, function as transmembrane receptors that ‘signal’ the presence of laminin on the cell surface to the cytoplasm. Lectins constitute a second class of laminin binding proteins that may augment integrin function by interacting with laminin carbohydrate. Caution must be used in ascribing functions to other laminin binding proteins, especially cytosolic proteins.

We use a new model of metarepresentational development to predict a cognitive deficit which could explain a crucial component of the social impairment in childhood autism. One of the manifestations of a basic metarepresentational capacity is a ‘ theory of mind ’. We have reason to believe that autistic children lack such a ‘ theory ’. If this were so, then they would be unable to impute beliefs to others and to predict their behaviour. This hypothesis was tested using Wimmer (...) and Perner’s puppet play paradigm. Normal children and those with Down’s syndrome were used as controls for a group of autistic children. Even though the mental age of the autistic children was higher than that of the controls, they alone failed to impute beliefs to others. Thus the dysfunction we have postulated and demonstrated is independent of mental retardation and specific to autism. (shrink)

Psychologists and philosophers have recently been exploring whether the mechanisms which underlie the acquisition of ‘theory of mind’ (ToM) are best charac- terized as cognitive modules or as developing theories. In this paper, we attempt to clarify what a modular account of ToM entails, and why it is an attractive type of explanation. Intuitions and arguments in this debate often turn on the role of develop- ment: traditional research on ToM focuses on various developmental sequences, whereas cognitive modules are thought (...) to be static and ‘anti-developmental’. We suggest that this mistaken view relies on an overly limited notion of modularity, and we explore how ToM might be grounded in a cognitive module and yet still afford development. Modules must ‘come on-line’, and even fully developed modules may still develop internally, based on their constrained input. We make these points con- crete by focusing on a recent proposal to capture the development of ToM in a module via parameterization. (shrink)

AP‐2 is a recent significant addition to the list of transcription factors that have been demonstrated by targeted gene disruption to be essential for normal development. Two recent reports of AP‐2 null mutant mice(1,2) indicate that AP‐2 holds a key position in the network of genes and proteins controlling developmental pattern and morphogenesis, and that it is particularly important for development of the cranial region and for midline fusions.

Answering important public health questions often requires collection of sensitive information about individuals. For example, our understanding of how HIV is transmitted and how to prevent it only came about with people's willingness to share information about their sexual and drug-using behaviors. Given the scientific need for sensitive, personal information, researchers have a corresponding ethical and legal obligation to maintain the confidentiality of data they collect and typically promise in consent forms to restrict access to it and not to publish (...) identifying data.The interests of others, however, can threaten researchers' promises of confidentiality when legal demands are made to access research data. In some cases, the subject of the litigation is tightly connected to the research questions, and litigants' interest in the data is not surprising. Researchers conducting studies on tobacco or occupational or other chemical exposures, for example, are relatively frequent targets of subpoenas. (shrink)

Number concepts must support arithmetic inference. Using this principle, it can be argued that the integer concept of exactly ONE is a necessary part of the psychological foundations of number, as is the notion of the exact equality - that is, perfect substitutability. The inability to support reasoning involving exact equality is a shortcoming in current theories about the development of numerical reasoning. A simple innate basis for the natural number concepts can be proposed that embodies the arithmetic principle, supports (...) exact equality and also enables computational compatibility with real- or rational-valued mental magnitudes.

Researchers now commonly collect biospecimens for genomic analysis together with information from mobile devices and electronic health records. This rich combination of data creates new opportunities for understanding and addressing important health issues, but also intensifies challenges to privacy and confidentiality. Here, we elucidate the “web” of legal protections for precision medicine research by integrating findings from qualitative interviews with structured legal research and applying them to realistic research scenarios involving various privacy threats.

Human social intelligence comprises a wide range of complex cognitive and affective processes that appear to be selectively impaired in autistic spectrum disorders. The study of these neuro- developmental disorders and the study of canonical social intelligence have advanced rapidly over the last twenty years by investigating the two together. Specifically, studies of autism have provided important insights into the nature of ‘theory of mind’ abilities, their normal development and underlying neural systems. At the same time, the idea of impaired (...) development of the neurocognitive mechanisms underlying ‘theory of mind’ has shed new light on the nature of autistic disorders. This general approach is not restricted to the study of impairments but extends to mapping areas of social intelligence that are spared in autism. Here we investigate basic moral judgment and find that it appears to be substantially intact in children with autism who are severely impaired in ‘theory of mind’. At the same time, we extend studies of moral reasoning in normal development by way of a new control task, the ‘cry baby’ task. Cry baby scenarios, in which the distress of the victim is ‘unreasonable’ or ‘unjustified,’ do not elicit moral condemnation from normally developing preschoolers or from children with autism. Judgments of moral transgressions in which the victim displays distress are therefore not likely the result of a simple automatic reaction to the distress and more likely involve moral reasoning. Mapping the cognitive co-morbidity patterns of disordered development should encompass both impairments and sparings because both will be needed to make sense of the neural and genetic levels.

The question 'Why should I obey the law?' introduces a contemporary puzzle that is as old as philosophy itself. The puzzle is especially troublesome if we think of cases in which breaking the law is not otherwise wrongful, and in which the chances of getting caught are negligible. Philosophers from Socrates to H.L.A. Hart have struggled to give reasoned support to the idea that we do have a general moral duty to obey the law but, more recently, the greater number (...) of learned voices has expressed doubt that there is any such duty, at least as traditionally conceived.

Relationships, jobs, and health behaviors-these are what New Year's resolutions are made of. Every year millions resolve to adopt a better diet, exercise more, become fit, or lose weight but few put into practice the health behaviors they aspire to. For those who successfully begin, the likelihood that they will maintain these habits is low. Healthcare professionals recognize the importance of these, and other, health behaviors but struggle to provide their patients with the tools necessary for successful maintenance of their (...) medical regimens. The thousands of research papers that exist on patient adherence and health behavior change can leave professionals overwhelmed. This book synthesizes the results from more than 50 years of empirical research, resulting in simple, powerful, and practical guidance for health professionals who want to know the most effective strategies for helping their clients to put long-term health-relevant behavior changes into practice. It advocates a straightforward 3-ingredient model: Before a person can change, they must know what change is necessary ; desire the change ; and then have the tools to achieve and maintain the change. This book is designed to be informative and compelling, but its numerous anecdotes and examples render it engaging and entertaining, as well. Written for a practitioners and students of medicine, chiropractic, osteopathy, nursing, health education, physician assistant programs, dentistry, clinical and health psychology, marriage and family counseling, social work, school psychology, and care administrators -- and for lay persons who wish to take an active role in their health, this book brings together major empirically-based findings within the field and provides succinct, evidence-based recommendations and strategies for using these findings to make real changes.
