This study examined the influence of sex and racial discrimination on academic alienation among Iranian university students. Two groups of 60 girls and 60 boys were sampled through multi-stage cluster sampling from among first-year Tabriz University students in Tabriz, Iran. All participants, between18 and 22, were asked to respond on an academic alienation questionnaire. The findings of a two-way ANOVA revealed that girls and Turkish speakers had higher levels of academic alienation compared to boys and Persian speakers. An investigation of (...) interactional effects indicated that Turkish girls demonstrated the highest levels of academic alienation, with no significant effects in the powerlessness dimension. Finally, the effects of the factors relevant to academic alienation were discussed. (shrink)

BackgroundThe ARRIVE (Animal Research: Reporting of In Vivo Experiments) guidelines are widely endorsed but compliance is limited. We sought to determine whether journal-requested completion of an ARRIVE checklist improves full compliance with the guidelines.MethodsIn a randomised controlled trial, manuscripts reporting in vivo animal research submitted to PLOS ONE (March–June 2015) were randomly allocated to either requested completion of an ARRIVE checklist or current standard practice. Authors, academic editors, and peer reviewers were blinded to group allocation. Trained reviewers performed outcome adjudication (...) in duplicate by assessing manuscripts against an operationalised version of the ARRIVE guidelines that consists 108 items. Our primary outcome was the between-group differences in the proportion of manuscripts meeting all ARRIVE guideline checklist subitems.ResultsWe randomised 1689 manuscripts (control: n = 844, intervention: n = 845), of which 1269 were sent for peer review and 762 (control: n = 340; intervention: n = 332) accepted for publication. No manuscript in either group achieved full compliance with the ARRIVE checklist. Details of animal husbandry (ARRIVE subitem 9b) was the only subitem to show improvements in reporting, with the proportion of compliant manuscripts rising from 52.1 to 74.1% (X2 = 34.0, df = 1, p = 2.1 × 10−7) in the control and intervention groups, respectively.ConclusionsThese results suggest that altering the editorial process to include requests for a completed ARRIVE checklist is not enough to improve compliance with the ARRIVE guidelines. Other approaches, such as more stringent editorial policies or a targeted approach on key quality items, may promote improvements in reporting. (shrink)

The employment of mythological language and imagery by an Epicurean poet - an adherent of a system not only materialist, but overtly hostile to myth and poetry - is highly paradoxical. This apparent contradiction has often been ascribed to a conflict in the poet between reason and intellect, or to a desire to enliven his philosophical material with mythological digressions. This book attempts to provide a more positive assessment of Lucretius' aims and methodology by considering the poet's attitude to myth, (...) and the role which it plays in the De Rerum Natura, against the background of earlier and contemporary views. The author suggests that Lucretius was not only aware of the tension between his two roles as philosopher and poet, but attempted to resolve it by developing his own, Epicurean poetic, together with a bold and innovative theory of the origins and meaning of myth.

Physical Relativity explores the nature of the distinction at the heart of Einstein's 1905 formulation of his special theory of relativity: that between kinematics and dynamics. Einstein himself became increasingly uncomfortable with this distinction, and with the limitations of what he called the 'principle theory' approach inspired by the logic of thermodynamics. A handful of physicists and philosophers have over the last century likewise expressed doubts about Einstein's treatment of the relativistic behaviour of rigid bodies and clocks in motion in (...) the kinematical part of his great paper, and suggested that the dynamical understanding of length contraction and time dilation intimated by the immediate precursors of Einstein is more fundamental. Harvey Brown both examines and extends these arguments, after giving a careful analysis of key features of the pre-history of relativity theory. He argues furthermore that the geometrization of the theory by Minkowski in 1908 brought illumination, but not a causal explanation of relativistic effects. Finally, Brown tries to show that the dynamical interpretation of special relativity defended in the book is consistent with the role this theory must play as a limiting case of Einstein's 1915 theory of gravity: the general theory of relativity.Appearing in the centennial year of Einstein's celebrated paper on special relativity, Physical Relativity is an unusual, critical examination of the way Einstein formulated his theory. It also examines in detail certain specific historical and conceptual issues that have long given rise to debate in both special and general relativity theory, such as the conventionality of simultaneity, the principle of general covariance, and the consistency or otherwise of the special theory with quantum mechanics. Harvey Brown' s new interpretation of relativity theory will interest anyone working on these central topics in modern physics. (shrink)

Understanding what it means toconsent is of considerable importance sincesignificant moral issues depend on how this actis defined. For instance, determining whetherconsent has occurred is the deciding factor insexual assault cases; its proper occurrence isa necessary condition for federally fundedhuman subject research. Even though mosttheorists recognize the legal and moralimportance of consent, there is still littleagreement concerning how consent should bedefined, or whether different domains involvingconsent demand context-specific definitions.Understanding what it means to consent isfurther complicated by the fact that currentlegal (...) conceptions are not necessarily groundedin argument; they typically depend on appealsto authority and precedent. The purpose ofthis paper is to use speech act theory toprovide a theoretically grounded conception ofconsent; such a conception can aid in the justresolution of legal and moral disputes thathinge on whether an act of consent occurred.

The overwhelming importance of Lucretius' De Rerum Natura for the interpretation of the Georgics is recognized by almost all critics. As W. Y. Sellar expressed it over a hundred years ago, ‘the influence, direct and indirect, exercised by Lucretius on the thought, composition and even the diction of the Georgics was perhaps stronger than that ever exercised, before or since, by one poet on the work of another’. Richard Thomas' recent commentary attempts to play down the extent of this influence, (...) contending that ‘the debt of Virgil to Lucretius in the Georgics is predominantly formal’, and manifests itself chiefly on a verbal level, whereby the poet seeks ‘to create a didactic appearance for his poem’. The aim of this paper is to reassert the pervasive importance of Lucretian ideas, as well as Lucretian language, throughout the poem, and particularly in Virgil's presentation of the physical and metaphysical relationships between man and beast.

Method as Identity considers how social identity shapes methodological standpoints. With a refreshing hip hop sensibility, Miller and Driscoll reorient the contemporary academic study of religion toward recognition of the costs and benefits of manufacturing “critical” distance from our objects of study.

John Conington was a towering figure in Victorian scholarship, not least because of his remarkably sensitive and literate commentaries on Virgil’s _Aeneid. _The three-volume cloth edition of _The Works of Virgil_, begun by Conington in 1852, has been unavailable for over a century, except in rare second-hand sets. Now, for the first time, the whole of Conington’s work is being reissued in a set of six paperback volumes. Each volume includes a new introduction by an established scholar, setting Conington's commentary (...) in context, as well as a general introduction to Conington’s work by Philip Hardie, who offers a fresh appreciation of the work.

Prior knowledge structures (or schemas) confer multiple behavioral benefits. First, when we encounter information that fits with prior knowledge structures, this information is generally better learned and remembered. Second, prior knowledge can support prospective planning. In humans, memory enhancements related to prior knowledge have been suggested to be supported, in part, by computations in prefrontal and medial temporal lobe cortex. Moreover, animal studies further implicate a role for the hippocampus in schema-based facilitation and in the emergence of prospective planning signals (...) following new learning. To date, convergence across the schema-enhanced learning and memory literature may be constrained by the predominant use of hippocampally dependent spatial navigation paradigms in rodents, and non-spatial list-based learning paradigms in humans. Here, we targeted this missing link by examining the effects of prior knowledge on human navigational learning in a hippocampally dependent virtual navigation paradigm that closely relates to foundational studies in rodents. Outside the scanner, participants overlearned Old Paired Associates (OPA – item-location associations) in multiple spatial environments, and they subsequently learned New Paired Associates (NPA – new item-location associations) in the environments while undergoing fMRI. We hypothesized that greater OPA knowledge precision would positively affect NPA learning, and that the hippocampus would be instrumental in translating this new learning into prospective planning of navigational paths to NPA locations. Behavioral results revealed that OPA knowledge predicted one-shot learning of NPA locations, and neural results indicated that one-shot learning was predicted by the rapid emergence of performance-predictive prospective planning signals in hippocampus. Prospective memory relationships were not significant in parahippocampal cortex and were marginally dissociable from the primary hippocampal effect. Collectively, these results extend understanding of how schemas impact learning and performance, showing that the precision of prior spatial knowledge is important for future learning in humans, and that the hippocampus is involved in translating this knowledge into new goal-directed behaviors.

This book focuses on social phenomenon that impact the lives of adolescent females of color. The authors highlight the daily challenges that African-American, Chicana, and Puerto Rican teenage girls face with respect to peer and family influences, media stereotyping, body image, community violence, pregnancy, and education. The authors also emphasize the incredible resiliency that young women possess in countering many of the social barriers confronting them.

An embodied movement-planning field cannot account for behavior and cognition more abstract than that of reaching. Instead, we propose an affordance field, and we sketch how it could enhance the analysis of the A-not-B error, underlie cognition, and serve as a base for language. Admittedly, a dynamic systems account of an affordance field awaits significant further development.

Decades of research have focused on children's reasoning about math equivalence problems for both practical and theoretical insights. Not only are math equivalence problems foundational in arithmetic and algebra, they also represent a class of problems on which children's thinking is resistant to change. Feedback is one instructional tool that can serve as a key trigger of cognitive change. In this paper, we review all experimental studies on the effects of feedback on children's understanding of math equivalence. Meta-analytic results indicate (...) that feedback has positive effects for low-knowledge learners and negative effects for high-knowledge learners, and these effects are stronger for procedural outcomes than conceptual outcomes. Findings highlight the variable influences of feedback on math equivalence understanding and suggest that models of thinking and reasoning need to consider learner characteristics, learning outcomes, and learning materials, as well as the dynamic interactions among them.

Senior managers are important to the successful management of ethics in organizations. Therefore, their perceptions of organizational ethics are important. In this study, we propose that senior managers are likely to have a more positive perception of organizational ethics than lower level employees do largely because of their managerial role and their corresponding identification with the organization and need to protect the organization’s image as well as their own identity. By contrast, lower level employees are more likely to be cynical (...) about the organization’s ethics. In order to compare senior managers’ and lower level employees’ perceptions of ethics in the organization, we surveyed randomly selected senior managers and lower level employees in three firms. We found that perceptions of ethics in the organization differed predictably across levels, with senior managers’ perceptions being significantly more positive and lower level employees’ perceptions being more negative. Implications for practice and research are discussed. (shrink)

Only a few studies have disaggregated homicide rates by relationship type or gender, with little investigation of homicide trends in adult marital and other intimate relationships. The current study documents patterns of homicide between opposite gender relational partners for the twelve years of 1976 through 1987 based on Supplementary Homicide Report Data, comparing rates between couples in marital and nonmarital relationships. Analyses reveal that the homicide rate for married couples declined somewhat during this period, although the drop in the rate (...) of wives killing husbands was greater than the drop in the rate of husbands killing wives. However, homicides involving unmarried couples followed a very different pattern. Whereas the lethal victimization rate for men in unmarried relationships varied unsystematically over time from 1976 through 1987, the rate of unmarried women being killed by their male partners increased significantly. Findings demonstrate the importance of disaggregating homicide data by gender and relationship type so that crucial differences can be detected. (shrink)

David Brown (b. 1948) is a Scottish Episcopal priest and theologian whose work covers a vast terrain spanning methodological divisions between philosophy, Christian theology, religious studies, the arts and culture. Early work on the Trinity and Incarnation led to a Newman-inspired articulation of Scripture as tradition, and, related to this, the exploration of tradition as revelation with reference to a wide range of human experience. Moving from materially-mediated divine presence to culturally-mediated revelation, Brown's phenomenology of religious experience amounts (...) to a transformed natural religion along sacramental lines. Essays in this volume consider Brown's wide ranging and generative contributions in three parts: 1) Butler & Newman, 2) Incarnation & Trinity, and 3) Sacramentality & the Arts, with a concluding response from Brown himself that addresses 'religious experience and revelation', as well as 'secular culture and religious distinctiveness'.

In early March 2014, some of the members of Culture on the Edge—a scholarly research collaboration of seven scholars of religion, interested in more theoretically sophisticated studies of identity, and all of whom are at different career stages and at a variety of North American institutions—had a conversation online on the use of the terms “critique” and “critical,” terms widely used in the field today but employed in such a variety of ways that the members of the group thought it (...) worthwhile to focus some attention on them. What follows is the transcript of their conversation. (shrink)
