The current practice for UK Research Ethics Committees is to invite researchers to attend meetings at which their applications are to be considered and the National Research Ethics Service strongly recommends researchers to attend. There are no available data, however, to substantiate the value of researchers' attendance and particularly on the extent to which their attendance may influence the initial decision of the committee. This study attempts to address whether it is in the researchers' interest to commit substantial time and (...) resource to attend a REC meeting through using the REC decision on the research proposal as the main outcome measure.

The current practice for UK research ethics committees is to invite researchers to attend meetings at which their applications are to be considered and for student-based research the National Research Ethics Service recommends supervisors to attend. This study aims to identify the extent to which students and their supervisors attend NHS REC meetings and whether attendance is associated with the initial outcomes of RECs.

This paper investigates relationships between men’s testosterone and family life in a sample of approximately 350 Jamaican fathers of children 18–24 months of age. The study recognizes the role of testosterone as a proximate mechanism coordinating and reflecting male life history allocations within specific family and cultural contexts. A sample of Jamaican fathers and/or father figures reported to an assessment center for an interview based on a standardized questionnaire and provided a saliva sample for measuring testosterone level. Outcomes measured include (...) subject demographics such as age and relationship status as well as partnership quality and sexuality and paternal attitudes and behavior. The variation in these fathers’ relationship status was not associated with men’s testosterone. Too few stepfathers participated to enable a direct test of the prediction that stepfathers would have higher testosterone than biological fathers, although fathers who reported living with partners’ children did not have higher testosterone than fathers not reporting residing with a non-biological child. Fathers’ relationship quality was negatively related to their testosterone. Measures of paternal attitudes and behavior were not related to fathers’ testosterone. Consistent with previous ethnography, this sample of Jamaican fathers exhibited variable life history profiles, including residential status. We discuss why fathers’ relationship quality was found to be negatively related to their testosterone level, but other predictions were not upheld. (shrink)

Previous research in North America has supported the view that male involvement in committed, romantic relationships is associated with lower testosterone (T) levels. Here, we test the prediction that undergraduate men involved in committed, romantic relationships (paired) will have lower T levels than men not involved in such relationships (unpaired). Further, we also test whether these differences are more apparent in samples collected later, rather than earlier, in the day. For this study, 107 undergraduate men filled out a questionnaire and (...) collected one saliva sample (from which a subject’s T level was measured) at various times across the day. As in previous studies, men involved in committed, romantic relationships had lower salivary T levels, though only during later times of the day. Furthermore, additional analysis of the variation among unpaired subjects indicated that men without prior relationship experience had lower T levels than experienced men. Finally, while paired men as a group had lower T levels than unpaired men, those men at the earliest stage (less than six months) of a current relationship had higher T levels than unpaired men as well as men in longer-term relationships. These results suggest that variation in male testosterone levels may reflect differential behavioral allocation to mating effort. (shrink)

David Gray Carlson and Peter Goodrich argue that the postmodern legal mind can be characterized as having shifted the focus of legal analysis away from the modernist understanding of law as a system that is unitary and separate from other aspects of culture and society. In exploring the various "other dimensions" of law, scholars have developed alternative species of legal analysis and recognized the existence of different forms of law. Carlson and Goodrich assert that the postmodern legal mind (...) introduced a series of "minor jurisprudences" or partial forms of legal knowledge, which both compete with and subvert the modernist conception of a unitary system of law. In doing so scholars from a variety of disciplines pursue the implications of applying the insights of their disciplines to law. Carlson and Goodrich have assembled in this volume essays from some of our leading thinkers that address what is arguably one of the most fundamental of interdisciplinary encounters, that of psychoanalysis and law. While psychoanalytic interpretations of law are by no means a novelty within common law jurisprudence, the extent and possibilities of the terrain opened up by psychoanalysis have yet to be extensively addressed. The intentional subject and "reasonable man" of law are disassembled in psychoanalysis to reveal a chaotic and irrational libidinal subject, a sexual being, a body and its drives. The focus of the present collection of essays is upon desire as an inner law, upon love as an interior idiom of legality, and represents a signficant and at times surprising development of the psychoanalytic analysis of legality. These essays should appeal to scholars in law and in psychology. The contributors are Drucilla Cornell, Jacques Derrida, Peter Goodrich, Pierre Legendre, Alain Pottage, Michel Rosenfeld, Renata Salecl, Jeanne L. Schroeder, Anton Schutz, Henry Staten, and Slavoj Zizek. David Gray Carlson is Professor of Law, Benjamin Cardozo School of Law, Yeshiva University.

This book offers both theoretical overviews and practical approaches for educators, academics, education students and parents who are interested in transforming schools. It encourages reinvigorating approaches to learning and teaching that can easily be integrated into both public and private K-12 school classrooms, with many ideas also applicable to higher education. It supports an educational system based on the beliefs that heart and spirit are intertwined with mind and intellect, and that inner peace, wisdom, compassion, and conscience can be developed (...) together with academic content and skills.

Molday and Hsu review results from in vitro experiments, which indicate that Ca-bound calmodulin reduces the cGMP sensitivity of the cyclic nucleotide-gated channel of photoreceptor cells, and speculate about the role they might play in the recovery of the light response. We discuss results from in vivo experiments that argue against the participation of Ca-calmodulin in photorecovery.

The ratio of index- and ring-finger lengths is thought to be related to prenatal androgen exposure, and in many, though not all, populations, men have a lower average digit ratio than do women. In many studies an inverse relationship has been observed, among both men and women, between 2D:4D ratio and measures of athletic ability. It has been further suggested that, in hunter-gatherer populations, 2D:4D ratio might also be negatively correlated with hunting ability, itself assumed to be contingent on athleticism. (...) This hypothesis has been tested using endurance running performance among runners from a Western, educated, and industrialized population as a proximate measure of hunting ability. However, it has not previously been tested among actual hunter-gatherers using more ecologically valid measures of hunting ability and success. The current study addresses this question among Tanzanian Hadza hunter-gatherers. I employ a novel method of assessing hunting reputation that, unlike previous methods, allows granular distinctions to be made between hunters at all levels of perceived ability. I find no statistically significant relationship between digit ratio and either hunting reputation or two important hunting skills. I confirm that Hadza men have higher mean 2D:4D ratios than men in many Western populations. I discuss the notion that 2D:4D ratio may be the consequence of an allometric scaling relationship between relative and absolute finger lengths. Although it is difficult to draw clear conclusions from these results, the current study provides no support for the theorized relationship between 2D:4D ratio and hunting skill. (shrink)

Clinical populations sometimes demonstrate difficulties forgetting stimuli related to their trauma-related disorder, perhaps because their intense personal connection to these stimuli produce deficits in the inhibitory control abilities necessary for forgetting. The present work examined this possibility for people who have high levels of traits implicated in borderline personality disorder (BPD). In two well-powered studies, we found no evidence for deficits in forgetting specific to BPD traits, even for people with clinically significant levels of the traits, contrary to previous studies. (...) The present experiments updated the designs from earlier experiments to employ the most contemporary methods to examine directed forgetting recommended by recent reviews. With these improved methods, Study 1 found that participants showed significant directed forgetting for BPD-related words independent of their level of BPD traits, perhaps because the BPD-related words were so strongly associated with one another. Study 2 found that when we removed the strong relatedness between the stimuli, forgetting of BPD-relevant words was significant and did not interact with BPD symptomology. We concluded that in contrast to people with PTSD who show specific inhibitory deficits for trauma-related works, people with BPD show normal, intact inhibitory control even for words that they should find threatening.

Throughout the biological and biomedical sciences there is a growing need for, prescriptive ‘minimum information’ (MI) checklists specifying the key information to include when reporting experimental results are beginning to find favor with experimentalists, analysts, publishers and funders alike. Such checklists aim to ensure that methods, data, analyses and results are described to a level sufficient to support the unambiguous interpretation, sophisticated search, reanalysis and experimental corroboration and reuse of data sets, facilitating the extraction of maximum value from data sets (...) them. However, such ‘minimum information’ MI checklists are usually developed independently by groups working within representatives of particular biologically- or technologically-delineated domains. Consequently, an overview of the full range of checklists can be difficult to establish without intensive searching, and even tracking thetheir individual evolution of single checklists may be a non-trivial exercise. Checklists are also inevitably partially redundant when measured one against another, and where they overlap is far from straightforward. Furthermore, conflicts in scope and arbitrary decisions on wording and sub-structuring make integration difficult. This presents inhibit their use in combination. Overall, these issues present significant difficulties for the users of checklists, especially those in areas such as systems biology, who routinely combine information from multiple biological domains and technology platforms. To address all of the above, we present MIBBI (Minimum Information for Biological and Biomedical Investigations); a web-based communal resource for such checklists, designed to act as a ‘one-stop shop’ for those exploring the range of extant checklist projects, and to foster collaborative, integrative development and ultimately promote gradual integration of checklists.

A large body of research links testosterone and cortisol to male-male competition. Yet, little work has explored acute steroid hormone responses to coalitional, physical competition during middle childhood. Here, we investigate testosterone, dehydroepiandrosterone, androstenedione, and cortisol release among ethnically Chinese boys in Hong Kong, aged 8–11 years, during a soccer match and an intrasquad soccer scrimmage, with 63 participants competing in both treatments. The soccer match and intrasquad soccer scrimmage represented out-group and in-group treatments, respectively. Results revealed that testosterone showed (...) no measurable change. DHEA increased during both treatments in the majority of participants and the degree of change had no relation to independent variables or covariate measures. Most boys experienced androstenedione increases during match play, but no significant differences during the intrasquad soccer scrimmage competitions. The magnitude of change differed significantly between treatments and was positively associated with age. These latter findings suggest boys’ androstenedione responses may be sensitive to competitor type. For most subjects, cortisol significantly increased during match play, decreased during the intrasquad soccer scrimmage, and differed significantly between treatments, suggesting each treatment promoted a different psychological state among competitors. Cortisol/DHEA molar ratio decreased during the intrasquad scrimmage, suggestive of a more relaxed mental state. These data shed new light on potential proximate mechanisms associated with coalitional competition among prepubescent boys, with relevance to adrenarche and life history theory. (shrink)

A great deal of interest and excitement surround the interface between the philosophy of biology and the philosophy of psychology, yet the area is neither well defined nor well represented in mainstream philosophical publications. This book is perhaps the first to open a dialogue between the two disciplines. Its aim is to broaden the traditional subject matter of the philosophy of biology while informing the philosophy of psychology of relevant biological constraints and insights.The book is organized around six themes: functions (...) and teleology, evolutionary psychology, innateness, philosophy of mind, philosophy of science, and parallels between philosophy of biology and philosophy of mind. Throughout, one finds overlapping areas of study, larger philosophical implications, and even larger conceptual ties. Woven through these connections are shared concerns about the status of semantics, scientific law, evolution and adaptation, and cognition in general. Contributors André Ariew, Mark A.

That question has been with us ever since medical technology began pushing back the limits of viability from the traditional 28 weeks of gestation to something closer to 23 weeks today. It requires ethical reflection about when a human life is worth trying to save and what role the risk of serious disability should play in that decision.

From the late nineteenth to twentieth century, the Bhagavad-Gītā became a transnational text influenced and molded by British colonialism and Orientalism. In this article, I argue that a particularly influential western figure, Peter Brook, adapted and represented the Gītā for a transnational audience in ways that expanded a neocolonial and Orientalist interpretive horizon for its contemporary reception. This essay examines how Brook’s particular approach to and universalist representation of the Gītā reveal an important decolonial paradox: the extension of colonial (...) relations into artistic and scholarly exchanges when attempting to enhance a text’s cross-cultural intelligibility. I advance this argument by critically exploring Brook’s universalist claims and ethical reflections on war, showing how his neocolonial vision of order—along with his impulse for control and speedy consumption of “performance capital”—ultimately undercut his universalizing aspirations. Finally, this examination elucidates a positive strategy for addressing the decolonial paradox in a contemporary Indian setting. (shrink)

_Friedrich Schlegel's Lucinde and the Fragments _ was first published in 1971. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions. For the last century and a half, Friedrich Schlegel has enjoyed a reputation for being the critical grey eminence behind the coming to power of the Romantic Movement. It was Schlegel, in his three series of aphoristic fragments _, who actually first defined and (...) employed the word "romantic" in the present sense; and it was he who in a chaotic, fragmentary, and often mysterious but forceful manner first proclaimed the doctrine that was to usher in the modern age in literature. He too was among the first to put his new program into practice in the shape of his unfinished _Lucinde_,a work variously denounced as pornography and heralded as a forerunner of modern novelistic experimentation, and probably the most famous novel to come out of German Romanticism. Both the _Fragments _and _Lucinde_,along with a brilliant _tour de force_, the "Essay on Incomprehensibility," are available now for the first time in a complete English translation in this volume, together with a brief scholarly introduction. This translation will enable non-German readers to examine at first hand the work of a man whom Rene Wellck has called "one of the greatest critics of history." At a time when the function of criticism is coming once again under close skeptical scrutiny, Friedrich Schlegel's unorthodox, unsystematic but seminal critical mind—all of literature, philosophy, art, and history were grist to his mill—should find many sympathetic readers. The book will be of particular interest to theorists of literature and fiction, comparative literature scholars, and historians of the intellectual history of Germany, and it is appropriate for course use in German and comparative literature classes.

In lieu of an abstract, here is a brief excerpt of the content:Response to Paul Woodford, “A Liberal Versus Performance-Based Music Education?”Peter R. WebsterA study of the history of music teaching and learning in North America will likely reveal very few examples of extended and well-argued professional discourse. By "discourse" I mean a continuous expression or exchange of ideas designed to present contrasting views on important issues in the music teaching profession. Often our annual conventions are filled with presentations (...) that address a single perspective in research, pedagogy, or theory. "Special theme" issues of magazines are rarely devoted to contrasting points of view about music teaching and learning. Conferences are organized to promote single views on a subject, often speaking to a partisan audience that expects to be neither challenged to think in a contrary way nor encouraged to develop alternative perspectives.Of course there are some rare and wonderful exceptions. During my course on measurement and assessment in music, I frequently ask my students to read [End Page 208] the exchange in the pages of the Music Educators Journal during the late 1930s between James Mursell and Carl Seashore as they debated approaches to music aptitude testing.1 I recall the great exchange at the 1994 meeting of the Music Educators National Conference between Bennett Reimer and Edwin Gordon on the subject of music learning.2 In past eras, there have been notable "point-counterpoint" exchanges in the pages of the Bulletin of the Council of Research in Music Education,3 as well as interesting perspectives on completed doctoral dissertations that spawned some debate. More recently, contributions in Philosophy of Music Education Review have been notable, particularly given the recent upturn in published work and interest in music education philosophy that this very Symposium exemplifies. The formation of the MayDay group in recent years is no small example of this trend.4 I am sure that I have missed other examples. However, compare these few instances with the millions of pages that are written in our field and the hours of papers presented and conference sessions held and the examples of real discourse pale in comparison to the body of professional exchange.In his paper, especially in the early pages, Paul Woodford makes this point forcefully and effectively. He challenges us to consider just how few examples there are of real discourse within the profession. I enjoyed enormously the case made for liberal education as not defined by the teaching of a canon of great books or art works as an end but as a thoughtful discussion of ideas in light of con-temporary circumstance. The paper reminds us that the idea of criticism in our field need not be a negative concept in this current age of post-modern thought, but a positive mark of a maturing profession.I was sympathetic to Woodford's example of multiculturalism running the risk of becoming an absolutism to be imposed on children. I feel the same way at times about other trends in our field such as the rise of technology as a kind of end-experience or the encouragement of popular music in classrooms simply because it is such a dominant part of children's lives. Each of these aspects of modern music education is worthy of careful debate by intellectuals in our field in much more sophisticated ways then we see today. Woodford would have us believe that this is a major professional failure, and I tend to agree.Not to belabor this point too much, but what about the National Standards? How often do you see an article published in Music Educators Journal that actually takes issue with any aspect of the standards? Where is the national debate about the content, extension, redefinition, refocusing, and development of these standards? Are they so good that they are not the subject of at least some national debate?At core here, for me, is the notion that discourse involving critical comment leads not to a sense of competition for superiority but real understanding of complex [End Page 209] issues. Very little that is worth discussing is black and white, and nearly always there are levels of complex gray. Many of us learn this from our days on the high... (shrink)

‘Smart’ devices are becoming increasingly ubiquitous. While these sophisticated machines are useful for various purposes, they sometimes evoke feelings of eeriness or discomfort that constitute uncanniness, a much-discussed phenomenon in robotics research. Adult participants (N = 115) rated the uncanniness of a hypothetical future smart speaker that was described as possessing the mental capacities for experience, agency, neither, or both. The novel condition prompting participants to attribute both agency and experience to the speaker filled an important theoretical gap in the (...) literature. Consistent with the mind perception hypothesis of uncanniness (MPH; Gray & Wegner, 2012), participants in the with-experience condition rated the device significantly higher in uncanniness than those in the control condition and the with-agency condition. Participants in the with-both (experience and agency) condition also rated the device higher in uncanniness than those in the control condition and the with-agency condition, although this latter difference only approached statistical significance.

Carbon monoxide intoxication leads to acute and chronic neurological deficits, but little is known about the specific noxious mechanisms. 1 H magnetic resonance spectroscopy may allow insight into the pathophysiology of CO poisoning by monitoring neurochemical disturbances, yet only limited information is available to date on the use of this protocol in determining the neurological effects of CO poisoning. To further examine the short-term and long-term effects of CO on the central nervous system, we have studied seven patients with CO (...) poisoning assessed by gray and white matter MRS, magnetic resonance imaging and neuropsychological testing. Five patients suffered from acute high-dose CO intoxication and were in coma for 1–6 days. In these patients, MRI revealed hyperintensities of the white matter and globus pallidus and also showed increased choline and decreased N -acetyl aspartate ratios to creatine, predominantly in the white matter. Lactate peaks were detected in two patients during the early phase of high-dose CO poisoning. Two patients with chronic low-dose CO exposure and without loss of consciousness had normal MRI and MRS scans. On follow-up. five of our seven patients had long-lasting intellectual impairment, including one individual with low-dose CO exposure. The MRS results showed persisting biochemical alterations despite the MRI scan showing normalization of morphological changes. In conclusion, the MRS was normal in patients suffering from chronic low-dose CO exposure; in contrast, patients with high-dose exposure showed abnormal gray and white matter levels of NAA/Cr, Cho/Cr and lactate, as detected by 1 H MRS, suggesting disturbances of neuronal function, membrane metabolism and anaerobic energy metabolism, respectively. Early increases in Cho/Cr and decreases of NAA/Cr may be related to a poor long-term outcome, but confirmation by future studies is needed. (shrink)

Good academic practice is more than the avoidance of clear-cut cheating. It also involves navigation of the gray zones between cheating and good practice. The existing literature has left students’ understanding of gray zone practices largely unexplored. To begin filling in this gap, we present results from a questionnaire study involving N = 1639 undergraduate students from seven European countries representing all major disciplines. We show that large numbers of these students are unable to identify gray area (...) issues and lack sensitivity to the context dependence of these. We also show that a considerable proportion of students have a poor understanding of concepts like plagiarism and falsification, not only in gray zone scenarios, but also in cases of relatively clear-cut cheating. Our results are similar across the faculties and countries of study, and even for students who have attended academic integrity training. We discuss the implications of this for academic integrity training. (shrink)

If we accept that all plagiarism is wrong, the issue is black and white. But are there more challenging questions that color the issue with shades of gray that may influence or help clarify the ethical underpinnings of the act? Does intent matter? Does the venue matter? Does the form of writing matter? What about a professor when working as a private citizen, rather than in his/her academic role? Might plagiarism be mitigated when there is no associated financial gain? (...) Is a writer’s history that exhibits impeccable ethical integrity relevant? Should these factors, and/or other factors, even be considered in a university’s administrative response — or non-response? What might employing an ethical approach contribute to wrestling with the dilemma? The authors explore critical issues that might face a senior academic administrator when confronting the need to respond on behalf of a university to a charge of plagiarism leveled by an influential newspaper against a university professor for a social responsibility-focused opinion-editorial published in this newspaper.

Regular musical activity as a complex multimodal lifestyle activity is proposed to be protective against age-related cognitive decline and Alzheimer’s disease. This cross-sectional study investigated the association and interplay between musical instrument playing during life, multi-domain cognitive abilities and brain morphology in older adults from the DZNE-Longitudinal Cognitive Impairment and Dementia Study study. Participants reporting having played a musical instrument across three life periods were compared to controls without a history of musical instrument playing, well-matched for reserve proxies of education, (...) intelligence, socioeconomic status and physical activity. Participants with musical activity outperformed controls in global cognition, working memory, executive functions, language, and visuospatial abilities, with no effects seen for learning and memory. The musically active group had greater gray matter volume in the somatosensory area, but did not differ from controls in higher-order frontal, temporal, or hippocampal volumes. However, the association between gray matter volume in distributed frontal-to-temporal regions and cognitive abilities was enhanced in participants with musical activity compared to controls. We show that playing a musical instrument during life relates to better late-life cognitive abilities and greater brain capacities in OA. Musical activity may serve as a multimodal enrichment strategy that could help preserve cognitive and brain health in late life. Longitudinal and interventional studies are needed to support this notion. (shrink)

As I write this, in November 1971, people are dying in East Bengal from lack of food, shelter, and medical caxc. The suffering and death that are occurring there now axe not inevitable, 1101; unavoidable in any fatalistic sense of the term.

The decisions arid actions of human beings can prevent this kind of suffering. Unfortunately, human beings have not made the necessary decisions. At the individual level, people have, with very few exceptions, not responded to the situation in any signihczmt way.

Introduction These essays have been written over a period of about ten years and have already been published separately in various places. ...

For thirty years, Peter Singer's Practical Ethics has been the classic introduction to applied ethics. For this third edition, the author has revised and updated all the chapters and added a new chapter addressing climate change, one of the most important ethical challenges of our generation. Some of the questions discussed in this book concern our daily lives. Is it ethical to buy luxuries when others do not have enough to eat? Should we buy meat from intensively reared animals? (...) Am I doing something wrong if my carbon footprint is above the global average? Other questions confront us as concerned citizens: equality and discrimination on the grounds of race or sex; abortion, the use of embryos for research and euthanasia; political violence and terrorism; and the preservation of our planet's environment. This book's lucid style and provocative arguments make it an ideal text for university courses and for anyone willing to think about how she or he ought to live. (shrink)

Truthmaker theorists hold that propositions about higher-level entities (e.g. the proposition that there is a heap of sand) are often made true by lower-level entities (e.g. by facts about the configuration of fundamental particles). This generates a problem: what should we say about these higher-level entities? On the one hand, they must exist (since there are true propositions about them), on the other hand, it seems that they are completely superfluous and should be banished for reasons of ontological parsimony. Some (...) truthmaker theorists—most prominently David Armstrong—have tried to solve this puzzle by arguing that these entities are ‘an ontological free lunch’, i.e. real existents that are still ‘no addition of being’. This answer is prima facie attractive, but I argue in this paper that the standard approaches to truthmaking—modal theories and grounding theories—are unable to vindicate the doctrine of the ontological free lunch, and thus fail to solve the problem of higher-level entities. Fortunately, there is a non-standard account of truthmaking available, the reductive explanation account, which succeeds where the standard approaches fail. (shrink)

What is ethics? Where do moral standards come from? Are they based on emotions, reason, or some innate sense of right and wrong? For many scientists, the key lies entirely in biology---especially in Darwinian theories of evolution and self-preservation. But if evolution is a struggle for survival, why are we still capable of altruism? In his classic study The Expanding Circle, Peter Singer argues that altruism began as a genetically based drive to protect one's kin and community members but (...) has developed into a consciously chosen ethic with an expanding circle of moral concern. Drawing on philosophy and evolutionary psychology, he demonstrates that human ethics cannot be explained by biology alone. Rather, it is our capacity for reasoning that makes moral progress possible. In a new afterword, Singer takes stock of his argument in light or recent research on the evolution of morality.--Publisher's description. (shrink)

These new studies of Wittgenstein's Tractatus represent a significant step beyond recent polemical debate.

Since its original publication in 1975, this groundbreaking work has awakened millions of people to the existence of "speciesism"—our systematic disregard of nonhuman animals—inspiring a worldwide movement to transform our attitudes to animals and eliminate the cruelty we inflict on them. In Animal Liberation, author Peter Singer exposes the chilling realities of today’s "factory farms" and product-testing procedures—destroying the spurious justifications behind them, and offering alternatives to what has become a profound environmental and social as well as moral issue. (...) An important and persuasive appeal to conscience, fairness, decency, and justice, it is essential reading for the supporter and the skeptic alike. (shrink)
