Goal‐directed cognition is often discussed in terms of specialized memory structures like the “goal stack.” The goal‐activation model presented here analyzes goal‐directed cognition in terms of the general memory constructs of activation and associative priming. The model embodies three predictive constraints: (1) the interference level, which arises from residual memory for old goals; (1) the strengthening constraint, which makes predictions about time to encode a new goal; and (3) the priming constraint, which makes predictions about the role of cues in (...) retrieving pending goals. These constraints are formulated algebraically and tested through simulation of latency and error data from the Tower of Hanoi, a means‐ends puzzle that depends heavily on suspension and resumption of goals. Implications of the model for understanding intention superiority, postcompletion error, and effects of task interruption are discussed. (shrink)

Virtual heritage has been explained as virtual reality applied to cultural heritage, but this definition only scratches the surface of the fascinating applications, tools and challenges of this fast-changing interdisciplinary field. This book provides an accessible but concise edited coverage of the main topics, tools and issues in virtual heritage. -/- Leading international scholars have provided chapters to explain current issues in accuracy and precision; challenges in adopting advanced animation techniques; shows how archaeological learning can be developed in Minecraft; they (...) propose mixed reality is conceptual rather than just technical; they explore how useful Linked Open Data can be for art history; explain how accessible photogrammetry can be but also ethical and practical issues for applying at scale; provide insight into how to provide interaction in museums involving the wider public; and describe issues in evaluating virtual heritage projects not often addressed even in scholarly papers. -/- The book will be of particular interest to students and scholars in museum studies, digital archaeology, heritage studies, architectural history and modelling, virtual environments.

How can we increase awareness and understanding of other cultures using interactive digital visualizations of past civilizations? In order to answer the above question, this book first examines the needs and requirements of virtual travelers and virtual tourists. Is there a market for virtual travel? Erik Champion examines the overall success of current virtual environments, especially the phenomenon of computer gaming. Why are computer games and simulations so much more successful than other types of virtual environments? Arguments that virtual (...) environments are impeded by technological constraints or by a paucity of evaluation studies can only be partially correct, for computer games and simulations are also virtual environments. Many of the underlying issues are caused by a lack of engagement with the philosophical underpinnings of culture, presence and inhabitation, and there are few exemplars that engage the public with history and heritage using interactive media in a meaningful and relevant manner. The intention of Playing With the Past is to help designers and critics understand the issues involved in creating virtual environments that promote and disseminate historical learning and cultural heritage through a close study of the interactive design principles at work behind both real and virtual places. Topics discussed include the design of virtual environments, and especially virtual heritage environments, virtual place-making, cultural presence, the pros and cons of game-style interaction, augmented reality projects, and appropriate evaluation methods. Virtual heritage environments discussed in the book include projects from Antarctica, Australia, Mexico, Malta, Egypt, Babylon, the Netherlands, Cambodia, and India. (shrink)

The U.S. scientific community has long led the world in research on such areas as public health, environmental science, and issues affecting quality of life. These scientists have produced landmark studies on the dangers of DDT, tobacco smoke, acid rain, and global warming. But at the same time, a small yet potent subset of this community leads the world in vehement denial of these dangers. -/- Merchants of Doubt tells the story of how a loose-knit group of high-level scientists and (...) scientific advisers, with deep connections in politics and industry, ran effective campaigns to mislead the public and deny well-established scientific knowledge over four decades. Remarkably, the same individuals surface repeatedly-some of the same figures who have claimed that the science of global warming is "not settled" denied the truth of studies linking smoking to lung cancer, coal smoke to acid rain, and CFCs to the ozone hole. "Doubt is our product," wrote one tobacco executive. These "experts" supplied it. -/- Naomi Oreskes and Erik M. Conway, historians of science, roll back the rug on this dark corner of the American scientific community, showing how ideology and corporate interests, aided by a too-compliant media, have skewed public understanding of some of the most pressing issues of our era.

Previous research has found that more embodied insults are identified faster and more accurately than less embodied insults. The linguistic processing of embodied compliments has not been well explored. In the present study, participants completed two tasks where they identified insults and compliments, respectively. Half of the stimuli were more embodied than the other half. We examined the late positive potential component of event-related potentials in early, middle, and late time windows. Increased embodiment resulted in improved response accuracy to compliments (...) in both tasks, whereas it only improved accuracy for insults in the compliment detection task. More embodied stimuli elicited a larger LPP than less embodied stimuli in the early time window. Insults generated a larger LPP in the late time window in the insult task; compliments generated a larger LPP in the early window in the compliment task. These results indicate that electrophysiological correlates of emotional language perception are sensitive to both top-down and bottom-up processes. (shrink)

Veksler and Gunzelmann make an extraordinary claim, which is that sleep deprivation effects and the vigilance decrement are functionally equivalent. Extraordinary claims require extraordinary evidence, which is missing from Veksler and Gunzelmann's study. Their behavioral data offer only weak theoretical constraint, and to the extent their modeling exercise supports any position, it is that these two performance impairments involve functionally distinct underlying mechanisms.

The main object of this paper is to examine the new philosophical frame proposed by Alain Badiou and Slavoj Žižek and to show that it implies some traces of Sartre's philosophical and political heritage. According the project of Alain Badiou and Slavoj Žižek one should no longer accept today's constellation of freedom, particularistic truth and democracy, but to inscribe the issues of freedom and universal truth into a political project that attempts to re-activate a thinking of revolution. Their thinking consists (...) in the wager that it is still possible to provide a philosophical frame for this leftist emancipatory position that claims the dimension of the universal against the vicious circle of capitalist globalization-cum-particularization and, by following Marx's claim that there are formal affinities between the ambitions of emancipatory politics and the working mode of capitalism, takes up the struggle of universalism against globalization. It is only through this struggle for the universal that the intertwined processes of a constant expansion of the automatism of capital and "a process of fragmentation into closed identities," accompanied by "the culturalist and relativist ideology" can be suspended. It is precisely this constellation of revolutionary act, universal truth, subject, and militant community, that reveal some similarities with Sartre's concepts of the subject, the revolutionary action, the militant community a.o.

The notion of functionality is appropriately central to the Newell Test but is also critical at a lower level, in development of cognitive sub-theories. I illustrate, on one hand, how far this principle is from general acceptance among verbal theoreticians, and, on the other hand, how simulation models (here implemented within ACT-R) seem to drive the functional question automatically.

Although Caenorhabditis elegans was chosen and modified to be an organism that would facilitate a reductionist program for neurogenetics, recent research has provided evidence for properties that are emergent from the neurons. While neurogenetic advances have been made using C. elegans which may be useful in explaining human neurobiology, there are severe limitations on C. elegans to explain any significant human behavior.

For good reasons we often think about ethics and strategy as two opposing categories. But as surfaces in which we see social practices reflected, as abstract planes in which social consciousness resides and which subjectivities reinvent, they share some deep and perhaps uncomfortable similarities. In this paper, we question whether they are irreconcilable categories and, through a discussion of the paradoxes of strategy and the antinomies of ethics, we examine their fraught relationship in current economic responses to the crisis. First, (...) we outline the discursive topographies of strategy and ethics in respect to their abstract relations, and examine their integument in business ethics and strategy in context. Then, we show how there cannot be a simple coexistence of these two categories in organisational practice: one must in fact be subordinate to the other, although this subordination can produce the persistence of the other, even in its negation. Finally, we conclude that the asymmetrical nature of ethics and strategy entails that whereas ethics can immanently give rise to strategy, strategic questions on their own can only produce anti-systemic ethical responses.

ObjectiveStudies that examine disordered eating in samples of Asian individuals living in the United States frequently combine all individuals of Asian descent into a single group, which can obscure important differences between groups and their experiences of acculturation. The goal of the present study was to establish the relation of acculturation, internalization of appearance ideals, and religiosity as predicting body dissatisfaction and disordered eating in women of South and Southeast Asian descent.MethodWomen of SSEA descent aged 18–51 years completed a battery (...) of questionnaires that inquire about these variables. A path analysis was conducted with acculturation serving as the independent variable, religiosity and internalization of the thin ideal as mediators, and body dissatisfaction and disordered eating as dependent variables.ResultsDirect paths from acculturation to both body dissatisfaction and disordered eating were not significant. Thin ideal internalization completely accounted for the path from acculturation to both endogenous variables; whereas, religiosity did not significantly account for any indirect effect.DiscussionFor SSEA women, internalization of appearance ideals is a potentially greater risk factor for disordered eating than acculturation or religiosity. As this was an atemporal mediation analysis, more work needs to be done exploring predictors of internalization in this population and how that may impact the development of disordered eating.

BackgroundThe increased risk of developing attention-deficit hyperactivity disorder (ADHD) in extremely preterm infants is well-documented. Better understanding of perinatal risk factors, particularly those that are modifiable, can inform prevention efforts.MethodsWe examined data from the Extremely Low Gestational Age Newborns (ELGAN) Study. Participants were screened for ADHD at age 10 with the Child Symptom Inventory-4 (N = 734) and assessed at age 15 with a structured diagnostic interview (MINI-KID) to evaluate for the diagnosis of ADHD (N = 575). We studied associations (...) of pre-pregnancy maternal body mass index (BMI), pregestational and/or gestational diabetes, maternal smoking during pregnancy (MSDP), and hypertensive disorders of pregnancy (HDP) with 10-year and 15-year ADHD outcomes. Relative risks were calculated using Poisson regression models with robust error variance, adjusted for maternal age, maternal educational status, use of food stamps, public insurance status, marital status at birth, and family history of ADHD. We defined ADHD as a positive screen on the CSI-4 at age 10 and/or meeting DSM-5 criteria at age 15 on the MINI-KID. We evaluated the robustness of the associations to broadening or restricting the definition of ADHD. We limited the analysis to individuals with IQ ≥ 70 to decrease confounding by cognitive functioning. We evaluated interactions between maternal BMI and diabetes status. We assessed for mediation of risk increase by alterations in inflammatory or neurotrophic protein levels in the first week of life.ResultsElevated maternal BMI and maternal diabetes were each associated with a 55–65% increase in risk of ADHD, with evidence of both additive and multiplicative interactions between the two exposures. MSDP and HDP were not associated with the risk of ADHD outcomes. There was some evidence for association of ADHD outcomes with high levels of inflammatory proteins or moderate levels of neurotrophic proteins, but there was no evidence that these mediated the risk associated with maternal BMI or diabetes.ConclusionContrary to previous population-based studies, MSDP and HDP did not predict ADHD outcomes in this extremely preterm cohort, but elevated maternal pre-pregnancy BMI, maternal diabetes, and perinatal inflammatory markers were associated with increased risk of ADHD at age 10 and/or 15, with positive interaction between pre-pregnancy BMI and maternal diabetes.

The author investigates the notion of linguistic meaning in gender research. She approaches this basic problem by drawing upon two very different conceptions of language and meaning: that of the logician Gottlob Frege and that of the linguist Ferdinand de Saussure. Motivated by the controversial response the Anglo-American sex/gender debate received within the German context, the author focuses on the connection between this epistemological controversy among feminists and two discursive traditions of linguistic meaning , to show how philosophy of language (...) can contribute to current feminist debates.

Many organisations, both public and private, have established framework agreements with selected suppliers to benefit from purchasing synergies. Compliance to such contracts throughout the organisation is crucial to achieve the expected benefits. Yet, in most organisations, the purchasing of goods and services is carried out not just by the purchasing department, but by many individuals dispersed throughout the organisation. Such a situation of scattered responsibilities can easily set the scene for different types of non-compliant behaviours in terms of an organisation's (...) purchasing policies. Very little research has been conducted on non-compliant purchasing behaviour, also known as "maverick buying". In this article, we use a systematic literature review to identify different forms of maverick buying, ranging from unintentional maverick buying to straightforward sabotage. We validate these different forms of maverick buying and enrich our understanding of underlying reasons through a series of in-depth interviews with purchasing professionals. We bring forms and reasons together in a conceptual framework and propose avenues for future research. (shrink)

Using NORC annual survey data, the authors selected 21 questions describing respondent attitudes toward job, life in general, and financial status. Respondents were catigorized as management, white collar, blue collar, and those not affiliated with business organizations. Attitudes were compared across the four occupational groups. Little dissatisfaction was found in any but the blue collar group. Management as a group, and men as well as women managers showed high levels of satisfaction, with few significant differences found in responses by men (...) and women. This study does not support the earlier finding of widespread alienation in business firms. (shrink)

The period in the foundations of mathematics that started in 1879 with the publication of Frege's Begriffsschrift and ended in 1931 with Gödel's Über formal unentscheidbare Sätze der Principia Mathematica und verwandter Systeme I can reasonably be called the classical period. It saw the development of three major foundational programmes: the logicism of Frege, Russell and Whitehead, the intuitionism of Brouwer, and Hilbert's formalist and proof-theoretic programme. In this period, there were also lively exchanges between the various schools culminating in (...) the famous Hilbert-Brouwer controversy in the 1920s. -/- The purpose of this anthology is to review the programmes in the foundations of mathematics from the classical period and to assess their possible relevance for contemporary philosophy of mathematics. What can we say, in retrospect, about the various foundational programmes of the classical period and the disputes that took place between them? To what extent do the classical programmes of logicism, intuitionism and formalism represent options that are still alive today? These questions are addressed in this volume by leading mathematical logicians and philosophers of mathematics. (shrink)
