We conducted an online study of projected behavioral and emotional responses to escalating terrorist threat. The study employed scenarios in which terrorists targeted commercial airliners with missiles at an international airport. An important feature of attacks on commercial flights is that unlike many other terrorist threats, exposure to the risk can be controlled simply be refusing to fly. Nine scenarios were constructed by crossing two between-subjects factors, each with three levels: (1) planned government protective actions and (2) social norm, expressed (...) as variation in airline ticket sales. Scenarios also incorporated descriptions of three increasingly severe attacks; this was a within-subjects factor. After each description, we asked respondents to imagine they had planned a vacation to a destination 2,500 km away, and we examined their projected fear and behavior. Fear increased and more trips were canceled as the attacks escalated. Government protective actions and social norm had little impact on either fear or planned flying. (shrink)

Introduction - This paper is aimed at gaining more insight into the effects of camera-surveillance on behavior. This study investigates the effects of three different ways of ‘framing’ camera presence on cheating behavior and pro-social behavior. First, we explore the effect of presenting the camera as the medium through which an intimidating authority watches the participant. Second, we test the effect of presenting the camera as being a neutral, non-intimidating viewer. Third, we investigate whether a participant watching themselves via a (...) camera has an effect on their behavior. In contrast to most studies of camera surveillance, we will conduct our experiments in an indoor setting, enabling us to investigate behavior to a much greater detail. We will also explore possible moderating effects of personality traits. Methods - 86 students participated in this experiment, distributed over four conditions: three different ways of framing the camera presence, plus a control condition. Our main dependent variables were various kinds of cheating and pro-social behavior. We established the participant’s relevant personality traits in a separate session. Results - For cheating behavior, findings showed that the ‘authorative’ way of framing camera presence and the situation in which participants viewed themselves, differed significantly from a situation without camera-surveillance. We did not find significant effects of camera surveillance on pro-social behavior during the experiment. Looking at personality traits, we found an indication that people with an internal locus of control are more inclined to cheat when there is no camera present compared to people with an external locus of control. However, the effects of our manipulations were stronger. Conclusion - These results support the idea that the framing of a camera’s presence does indeed influence cheating behavior, adding to the preventive effects of camera-surveillance. Additionally, this study provides some valuable insights into the influence of camera presence on behavior in general. (shrink)

2. Because of the possibility of lies, or the misuse of language, I believe that Professor Hempel's formulation of the problem of empirical certainty must be interpreted as a convenient abbreviation, in linguistic terms, of a question about beliefs. A complete formulation of the question would have to make some reference to the speaker's beliefs as he utters an "experiential statement.".

The development of action and perception, and their relation in infancy is a central research area in socio-cognitive sciences. In this Perspective Article, we focus on the developmental variability and continuity of action and perception. At group level, these skills have been shown to consistently improve with age. We would like to raise awareness for the issue that, at individual level, development might be subject to more variable changes. We present data from a longitudinal study on the perception and production (...) of contralateral reaching skills of infants aged 7, 8, 9, and 12 months. Our findings suggest that individual development does not increase linearly for action or for perception, but instead changes dynamically. These non-continuous changes substantially affect the relation between action and perception at each measuring point and the respective direction of causality. This suggests that research on the development of action and perception and their interrelations needs to take into account individual variability and continuity more progressively. (shrink)

Background: Despite the growing potential of mobile-based technologies, innovative interventions targeting the reduction of acute stress in daily life remain under-researched. Music listening is an easy-to-administer activity that is associated with lower levels of biological and self-reported stress. However, the application of music as an intervention in moments of acute stress in daily life remains to be examined. We developed a just-in-time intervention delivering music in moments of stressful experiences in daily life and tested its feasibility using a mixed methods (...) approach.Methods: In this uncontrolled pilot study, the ecological momentary music intervention was tested by 10 chronically stressed women aged 23.5 ± 3.3 years. Over 18 consecutive days, whenever participants reported stressful experiences, they were encouraged to listen to a self-compiled playlist. Subjective stress levels and saliva samples were assessed at three time points per stress report. We analyzed app-based log data, in-the-moment responses, questionnaire data, and semi-structured interview data.Results: On average, participants’ compliance with the study protocol lay at 70%. Overall, 65 stressful experiences were reported, 51 of which were followed by music listening, for an average duration of 12:53 min. Complete data were provided for 46 stressful experiences. Participants reported immediate relaxation and distraction through music listening. The interviews revealed that the intervention was easy to use and that music listening in moments of perceived stress was viewed as a new and pleasant activity. Several aspects of the protocol were identified, which should be improved in future studies.Conclusion: Since repeated stressful experiences in daily life can pose a threat to physical and mental integrity, interventions that are easily applicable and deliver support when needed most are necessary. Following minor adaptations, the EMMI can be considered as a feasible approach to target psychobiological stress responses in daily life, which is worthy of investigation in future larger-scale trials.

This paper generalises and complements the work on combining temporal logics started by Finger and Gabbay [11, 10]. We present proofs of transference of soundness, completeness and decidability for the temporalisation of logics T for any flow of time, eliminating the original restriction that required linear time for the transference of those properties through logic combination. We also generalise such results to the external application of a multi-modal system containing any number of connectives with arbitrary arity, that respect normality.This generalisation (...) over generic flows of time propagates to other combinations of logics that can be interpreted in terms of temporalisations. In this way, the independent combination of temporal logics is studied over generic flows of time. We show the transfer of soundness, completeness and decidability for independent combination of temporal logics. Finally, we also discuss the independent combination of any finite number of normal multi-modal logics. (shrink)

Subset Spaces were introduced by L. Moss and R. Parikh in [8]. These spaces model the reasoning about knowledge of changing states.In [2] a kind of subset space called intersection space was considered and the question about the existence of a set of axioms that is complete for the logic of intersection spaces was addressed. In [9] the first author introduced the class of directed spaces and proved that any set of axioms for directed frames also characterizes intersection spaces.We give (...) here a complete axiomatization for directed spaces. We also show that it is not possible to reduce this set of axioms to a finite set. (shrink)

In a behavioral study we analyzed the influence of visual action primes on abstract action sentence processing. We thereby aimed at investigating mental motor involvement during processes of meaning constitution of action verbs in abstract contexts. In the first experiment, participants executed either congruous or incongruous movements parallel to a video prime. In the second experiment, we added a no-movement condition. After the execution of the movement, participants rendered a sensibility judgment on action sentence targets. It was expected that congruous (...) movements would facilitate both concrete and abstract action sentence comprehension in comparison to the incongruous and the no-movement condition. Results in Experiment 1 showed a concreteness effect but no effect of motor priming. Experiment 2 revealed a concreteness effect as well as an interaction effect of the sentence and the movement condition. The findings indicate an involvement of motor processes in abstract action language processing on a behavioral level. (shrink)

Critical posthumanists have observed that technoscientific developments are in the process of rewriting human ontology, fundamentally changing what it means to be human. While they argue that the posthuman breaks with the Cartesian liberal subject and embraces a more decentered ontology, their analyses remain firmly situated in a Cartesian world that marginalizes if not completely ignores questions about natality. This essay examines two filmic texts, Blade Runner 2049 and the AMC television show Humans, that are situated firmly in a posthuman (...) environment in which technoscience is seemingly rewriting the conditions of being human and blurring the boundary between human and machine, but which focus on natality and childhood and emphasize themes of parenting and growth and development. In doing so, they disclose shortcomings in critical posthumanism that can only be addressed when we give more serious attention to how natality shapes being human. (shrink)

With this issue we initiate the policy of expanding the scope of Tulane Studies in Philosophy to include, in addition to the work of members of the department, contributions from philosophers who have earned advanced degrees from Tulane and who are now teaching in other colleges and universities. The Editor THE LOGIC OF OUR LANGUAGE ROBERT L. ARRINGTON Wittgenstein wrote in the Tractatus that "logic is not a body of doctrine, but a mirror-image of the world. " 1 In line (...) with his suggestion that a proposition is a 'picture', Wittgenstein argued that propositions 'show' the logical structure of the real. He was insistent, however, that "the apparent logical form of a proposition need not be its real one. " 2 As a result of this we can misunderstand the structure of fact. Philosophical problems arise just when "the logic of our language is mis understood. " 3 It is common knowledge that much of this view of logic was rejected by Wittgenstein himself in the Philosophical Investi gations. There we are told that language has no ideal or sublime 4 logic which mirrors the structure of the extra-linguistic world. Consequently, inferences from the structure of language to the structure of that extra-linguistic world are invalid. Reality can be 'cut up' in any of a number of ways by language. Wittgenstein adopted a view of philosophy which would render that discipline a non-explanatory, non-critical study of the multiple ways in which language can be used. (shrink)

Vaesen asks whether goal maintenance and planning ahead are critical for innovative tool use. We suggest that these aptitudes may have an evolutionary foundation in motor planning abilities that span all primate species. Anticipatory effects evidenced in the reaching behaviors of lemurs, tamarins, and rhesus monkeys similarly bear on the evolutionary origins of foresight as it pertains to tool use.

Two recent papers1,2 report extensive nuclear DNA sequence from a 38,000‐year‐old Neandertal fossil, comparing it to modern humans and estimating when it diverged from, and whether it contributed to, our gene pool. Based on 65,250 and over a million base‐pairs of sequence across the genome, respectively, the groups arrived at slightly different interpretations. The data are an exciting and interesting new contribution, but are not surprising, and a sense of history and question helps put them in perspective.

This is the first of two special issues and the articles are grouped according to two themes: This first issue will feature articles that share a theme we call Technologies and the Political, while the second issue will feature the theme Subjectivities. However, we could equally consider them exercises in provincialization in the (counter)factual register in the first issue, and by affective historiography as conceptual-empirical labor(atory) in the second issue. What we have generally asked of all authors is to consider (...) that the relation between science and society is often heavily influenced by and identified in the intermediary figurations portrayed in the genre of science fiction.

Information on the factors influencing parents’ decision-making process following a lethal, life-limiting or severely debilitating prenatal diagnosis remains deficient. A comprehensive systematic review and meta-synthesis was conducted to explore the influencing factors for parents considering termination or continuation of pregnancy following identification of lethal, life-limiting or severely debilitating fetal abnormalities. Electronic searches of 13 databases were conducted. These searches were supplemented by hand-searching Google Scholar and bibliographies and citation tracing. Thomas and Harden’s thematic synthesis method was used to synthesise data (...) from identified studies. Twenty-four papers were identified and reviewed, but two papers were removed following quality assessment. Three main themes were identified through systematic synthesis. Theme 1, entitled ‘all life is precious’, described parents’ perception of the importance of the fetus’ life, a fatalistic view of their situation alongside moral implications as well as the implications decisions would have on their own life, in consideration of previous life experiences. Theme 2 contained two sub-themes which considered the parent’s own imagined future and the influence of other people’s experiences. Finally, Theme 3 presented three sub-themes which may influence their parental decision-making: These described parental consideration of the quality of life for their unborn child, the possibility of waiting to try for another pregnancy, and their own responsibilities and commitments. The first review to fully explore parental decision-making process following lethal, life-limiting, or severely debilitating prenatal diagnosis provided novel findings and insight into which factors influenced parents’ decision-making process. This comprehensive and systematic review provides greater understanding of the factors influential on decision-making, such as hope, morality and potential implications on their own and other’s quality of life, will enable professionals to facilitate supported decision-making, including greater knowledge of the variables likely to influence parental choices.

The mammalian dentition is a segmented organ system with shape differences among its serially homologous elements (individual teeth). It is believed to have evolved from simpler precursors with greater similarities in shape among teeth, and a wealth of descriptive data exist on changes to the dentition that have occurred within mammals. Recent progress has been made in determining the genetic basis of the processes that form an individual tooth, but patterning of the dentition as a whole (i.e. the number, location (...) and shape of the teeth) is less well understood. In contrast to similarly organized systems, such as the vertebral column and limb, Hox genes are not involved in specifying differences among elements. Nevertheless, recent work on a variety of systems is providing clues to the transcription factors and extracellular signalling molecules involved. (shrink)

Weiss, Propen, and Reid gather a diverse group of scholars to analyze the growing obsolescence of the human-object dichotomy in today's world. In doing so, Design, Mediation, and the Posthuman brings together diverse disciplines to foster a dialog on significant technological issues pertinent to philosophy, rhetoric, aesthetics, and science.

Background: Genetic research involving racial/ethnic populations has novel ethical implications for various stakeholders, but ethical acceptability among stakeholders regarding such research is not clear. Methods: As part of a multifaceted National Institute of Mental Health (NIMH)/National Human Genome Research Institute (NHGRI) funded survey, we used repeated-measures factorial multivariate analysis of variance (MANOVA) to compare the perspectives of institutional review board (IRB) chairs (n = 203), investigators (n = 183), and community members (n = 192) on the ethical acceptability of participating (...) in and reporting of psychiatric genetic research focused on racial/ethnic minority groups. Stakeholder views were assessed with two sets of three questions. Results: All stakeholder groups perceived participation in genetic studies focused on racial/ethnic groups as ethically acceptable and endorsed as ethical any decisions by racial/ethnic minorities to decline to participate in such studies if concerned about possible discrimination/stigmatization based on the study findings. Stakeholders disagreed considerably on the ethical acceptability of researchers or journal editors choosing not to publish genetic study results focused on racial/ethnic minority groups based on potential harm of the study findings. Conclusion: Findings show community and professional stakeholders support participation in genetic research focused on specific racial/ethnic groups but recognize that the results of such studies may contribute to discrimination or stigmatization. Stakeholders differed in their perspectives of investigators and editors in balancing ethical issues intrinsic to advancing science versus minimizing harm to potentially vulnerable populations.

Matter as such produces nothing, changes nothing, does nothing; and however convenient it may afterwards be to abbreviate our nomenclature and our descriptions, we must most carefully realize in the outset that the spermatozoon, the nucleus, the chromosomes or the germ-plasma can never act as matter alone, but only as seats of energy and as centres of force.Science is a human endeavor that is rarely if ever just about science: it is also a social, political, and economic enterprise. As such (...) it is structured around an ethos: a belief system, or theory, that accounts for the nature of relevant aspects of existence. Much like other belief systems in the broader culture in which they occur, we build stories in defense... (shrink)

Like _Beyond All Appearances_,_ _which it supplements, Paul Weiss’s new book is a fundamental work which faces all the hard issues which are not only at the heart of philosophy but at the core of our entire culture. Readers of Mr. Weiss’s phenomenology of religion will need no introduction to this new work which expands and clari­fies many of the issues raised in _Beyond All Appearances. _However, no knowl­edge of Paul Weiss’s previous books is required to understand (...) and appreciate this brilliant new exposition. Weiss’s plain style makes his ideas accessible to all intelligent readers, whether or not they have been trained as professional philosophers. Here in _First Considerations _Mr. Weiss addresses himself to such topics as actuality, internalization, evidence, names, substance, being, natures and possibilities, existence, unity and the cosmos—issues which have engrossed him as a moral philosopher and meta­physician throughout his distinguished career. In his progress through the ideas and issues expounded in this new book Mr. Weiss is concerned with the human condition distinctive of this species of ours. Rigorously applied, his moral philosophy is as complete and thorough as that of any of the major thinkers, and provides as complete a guide as, for example, that of Buddhism. A highly original work, no doubt well in advance of current trends in philosophy, _First Considerations _will provoke further thought and discussion and will be regarded as a seminal work in modern philosophical approaches.

A response to complex problems spanning disciplinary boundaries, Worlds of ScienceCraft offers bold new ways of conceptualizing ideas of science, sociology, and philosophy. Beginning with the historical foundations of civilization and progress, assumptions about the categories we use to talk about minds, identities, and bodies are challenged through case studies from mathematics, social cognition, and medical ethics.

Vascular calcifications are the consequence of several pathological conditions such as atherosclerosis, diabetes, hypercholesterolemia and chronic renal insufficiency. They are associated with risks of amputation, ischemic heart disease, stroke and increased mortality. A growing body of evidence indicates that vascular smooth muscle cells (VSMCs) undergo chondrogenic commitment eventually leading to vascular calcification, by mechanisms similar to those governing ossification in the cartilage growth plate. Our knowledge of the formation of cartilage growth plate can therefore help us to understand why and (...) how arteries calcify and, consequently, develop new therapeutic strategies. Reciprocally, thorough consideration of the events leading to ectopic chondrocyte differentiation appears crucial to further increase our understanding of growth plate formation. In this context, we will review the effects of known or suspected factors that promote chondrogenic differentiation in growth plate and arteries.
