The mechanisms for cultural transmission remain disputable and difficult to validate through observational field studies alone. If controlled experimental laboratory investigation reveals that a putative mechanism is demonstrable in the species under study, then inferences that the same mechanism is operating in the field observation are strengthened.

Over the past seventy-five years, the UN has evolved significantly, often in response to geopolitical dynamics and new waves of thinking. In some respects, the UN has registered remarkable achievements, stimulating a wide range of multilateral treaties, promoting significant growth of human rights, and at times playing a central role in containing and preventing large-scale armed conflict. As part of the special issue on “The United Nations at Seventy-Five: Looking Back to Look Forward,” this essay argues that the organization has (...) been the most impactful in three areas: producing, shaping, and driving key ideas, particularly on development and rights; generating such effective operational agencies as UNICEF and the World Food Program; and, especially in the immediate post–Cold War period, addressing major conflict risks through the Security Council. Since then, however, the UN has struggled to meet emerging challenges on many fronts and been increasingly hampered by internal ossification and institutional sprawl as well as internecine dysfunction. The twenty-first century has confronted the UN with further challenges relating most notably to climate change; to risks arising from new technologies; and to the increasingly fraught relationships between China, Russia, and the United States. If the past seventy-five years can offer one lesson, it is that new thinking and new ideas will need to drive the organization to evolve still further and faster, or else risk irrelevance. (shrink)

This paper presents methods to visualize the structure of trees that occur in genetic programming. These methods allow for the inspection of structure of entire trees even though several thousands of nodes may be involved. The methods also scale to allow for the inspection of structure for entire populations and for complete trials even though millions of nodes may be involved. Examples are given that demonstrate how this new way of “seeing” can afford a potentially rich way of understanding dynamics (...) that underpin genetic programming. The examples indicate further studies that might be enabled by visualizing structure at these scales. (shrink)

This paper examines masculinity in relation to the modern tracking shot in Daren Aronofsky's The Wrestler and Derek Cianfrance's The Place Beyond the Pines. These films make prominent use of a particular tracking shot in which the camera floats behind a male character, his head neatly centred in the frame. The camera in these ‘follow-shots’ seems unmistakably but loosely tethered to the character's body. This paper attempts to ascertain the phenomenological nature and critical significance of that relationship, which in recent (...) films expresses the intimate distance and dissonance between mobile cameras, masculinity and the male body in the twenty-first century.

The most important and common solution to the Pyrrhonian skeptic’s regress problem is foundationalism. Reason-giving must stop somewhere, argues the foundationalist, and the fact that it does stop does not threaten knowledge or justification. The foundationalist has a problem, though; while foundationalism might adequately answer skepticism, it does not allow for a satisfying reply to the skeptic. The feature that makes a belief foundationally justified is not the sort of thing that can be given to another as a reason. Thus, (...) if foundationalism is true, we can only fall silent in the face of a challenge to our epistemically basic beliefs. Call this the practical or existential problem of foundationalism. Thomas Reid offers a rather stunning solution to this problem. Humor, he thinks, can be used to defend basic beliefs which cannot be defended by argument. We develop and defend an account on which Reid is correct and emotions such as rueful amusement can be invoked to rationally persuade the skeptic to accept foundationally justified beliefs. Then, inspired by Kierkegaard, we extend the account to foundational moral and religious beliefs. (shrink)

Despite the interpersonal nature of family meetings and the frequency in which they occur, the clinical ethics literature is devoid of any rich descriptions of what clinical ethicists should actually be doing during family meetings. Here, we propose a framework for describing and understanding “transitioning” facilitation skills based on a retrospective review of our internal documentation of 100 consecutive cases wherein a clinical ethicist facilitated at least one family meeting. The internal documents were analyzed using qualitative methodologies, i.e., “codes”, to (...) identify emergent themes. We identified four different transitioning strategies clinical ethicists use to reach a meaningful resolution. These transitioning strategies serve as a jumping-off point for additional analyses, future research, evaluating clinical ethics consultation, and overall performance improvement of a consultation service.

Objective The establishment of patient-centered measures capable of empirically determining meaningful cognitive change after surgery can significantly improve the medical care of epilepsy patients. Thus, this study aimed to develop reliable change indices (RCIs) and standardized regression-based (SRB) change norms for a comprehensive neuropsychological test battery in the German language. Methods Forty-seven consecutive patients with temporal lobe epilepsy underwent neuropsychological assessments, both before and 12 months after surgery. Practice-effect-adjusted RCIs and SRB change norms for each test score were computed. To (...) assess their usefulness, the presented methods were applied to a clinical sample, and binary logistic regression analyses were conducted to model the odds of achieving improvement in quality of life (QOL) after surgery. Results The determined RCIs at 90% confidence intervals and the SRB equations for each test score included in the test battery are provided. Cohen’s kappa analyses revealed a moderate mean agreement between the two measures, varying from slight to almost perfect agreement across test scores. Using these measures, a negative association between improvement in QOL and decline in verbal memory functions after surgery was detected (adjusted odds ratio = 0.09, p = 0.006). Significance To the best of our knowledge, this study is the first to develop RCIs and SRB change norms necessary for the objective determination of neuropsychological change in a comprehensive test battery in the German language, facilitating the individual monitoring of improvement and decline in each patients’ cognitive functioning and psychosocial situations after epilepsy surgery. The application of the described measures revealed a strong negative association between improvement in QOL and decline in verbal memory functions after surgery. (shrink)

The idea of moral progress is a necessary presupposition of action for beings like us. We must believe that moral progress is possible and that it might have been realized in human experience, if we are to be confident that continued human action can have any morally constructive point. I discuss the implications of this truth for moral psychology. I also show that once we understand the complex nature and the complicated social sources of moral progress, we will appreciate why (...) we cannot construct a plausible comprehensive action-guiding theory of moral progress. Yet while the nature and sources of moral progress consistently thwart many theoretical hopes, the idea of moral progress is a plausible, critically important and morally constructive principle of historical interpretation.

Does martial arts practice contribute to psychological well-being in professional martial artists? If so, what are the specific ways that martial arts practice accomplishes this? It has been a long-standing and widely held belief that martial arts practice can contribute to psychological well-being, however, there has been a lack of empirical research in the psychological literature focused on investigating the details of this hypothesis. The purpose of this research is therefore to investigate the impact of a paradigmatic martial arts practice—shadowboxing—on (...) the psychological well-being of professional martial artists. In this article I present the results from an original empirical study on professional Muay Thai practitioners (n = 14) that reveals how a martial arts practice (shadowboxing) contributes to their overall psychological well-being by contributing to their positive emotions, engagement, relationships, meaning, and accomplishment. I present general results for how shadowboxing contributes to the psychological well-being of these professional martial artists overall, as well as more specific results for how shadowboxing contributes to the psychological well-being of these professional martial artists based on factors such as their gender, fight experience, and training location. This article also provides qualitative first-person reports from professional Muay Thai practitioners (n = 14) about their use of visualization and mental imagery and their experience of flow while shadowboxing, offering unique insight into the minds of professional martial artists as they are actively engaged in their craft. Finally, this article discusses the value and limitations of the present study and outlines suggestions for future research. (shrink)

This paper reviews recent applications of the Einstein- Rosen type space-times to some problems of modern cosmology. An extensive overview of inhomogeneous universes filled with gravitational waves, classical fields, and relativistic fluids is given. The dynamics of primordial inhomogeneities, such as gravitational and matter waves and shocks, their interactions, and the global evolution of the models considered, is presented in detail.

Belief in the existence of individual selves who are both knowers and agents in the world is for many philosophers an indispensable component of a reasonable view of experience. To be sure, some feminist and nonfeminist philosophers alike have challenged the ontological and epistemological commitments of conventional conceptions of the self. These philosophers have questioned, for instance, whether the self is some kind of unity which persists as a unity over time, and whether self‐knowledge is (at least in some degree) (...) possible. Those who challenge these commitments appear to deny the plausibility of the very idea of the self – though many would insist otherwise, or at least argue that the implausibility of that idea would pose no great difficulty for the project of making sense of human subjectivity. Yet many feminist philosophers presuppose both the reasonableness of the idea of the self and the importance of that idea to understanding human subjectivity and identity. In fact, some of the most important developments in feminist philosophy have involved efforts to understand the nature of the self. (shrink)

Monica Colvin-Adams,1 Nonyelum Harcourt,1 Robert LeDuc,2 Ganesh Raveendran,1 Yassir Sonbol,3 Robert Wilson,1 Daniel Duprez11Cardiovascular Division, University of Minnesota, Minneapolis, MN, USA; 2Division of Biostatistics University of Minnesota, Minneapolis, MN, USA; 3Cardiovascular Division, St Luke's Hospital System, Sugar Land, TX, USAObjective: Arterial elasticity is a functional biomarker that has predictive value for cardiovascular morbidity and mortality in nontransplant populations. There is little information regarding arterial elasticity in heart transplant recipients. This study aimed to characterize small and large artery elasticity in heart (...) transplant recipients in comparison with an asymptomatic population free of overt cardiovascular disease. A second goal was to identify demographic and clinical factors associated with arterial elasticity in this unique population.Methods: Arterial pulse waveform was registered noninvasively at the radial artery in 71 heart transplant recipients between 2008 and 2010. SAEs and LAEs were derived from diastolic pulse contour analysis. Comparisons were made to a healthy cohort of 1,808 participants selected from our prevention clinic database. Multiple regression analyses were performed to evaluate associations between risk factors and SAE and LAE within the heart transplant recipients.Results: LAE and SAE were significantly lower in heart transplant recipients than in the normal cohort. Female sex and history of ischemic cardiomyopathy were significantly associated with reduced LAE and SAE. Older age and the presence of moderate cardiac allograft vasculopathy were also significantly associated with reduced SAE. Transplant duration was associated with increased SAE.Conclusion: Heart transplants are associated with peripheral endothelial dysfunction and arterial stiffness, as demonstrated by a significant reduction in SAE and LAE when compared with a healthy population. Furthermore, cardiac allograft vasculopathy is associated with a significant reduction in SAE, suggesting a potential use in screening heart transplant recipients at risk for developing this complication.Keywords: heart transplant, endothelial function, arterial elasticity, cardiac allograft vasculopathy.

Some philosophers argue that martial arts training is maladaptive, contributes to psychological illness, and provides a social harm, whereas others argue that martial arts training is adaptive, contributes to psychological wellness, and provides a social benefit. This debate is important to scholars and the general public since beliefs about martial arts training can have a real impact on how we evaluate martial artists for job opportunities and career advancement, and in general, how we treat martial artists from different cultures in (...) our communities. This debate is also important for children and adults that have considered enrolling in martial arts training programs but remain uncertain about potential outcomes of training due to the lack of research in this area. This article therefore contributes to the literature on martial arts by (1) outlining a framework that characterizes psychological well-being in terms of five elements, (2) discussing how results from empirical research support the hypothesis that Muay Thai training can contribute to psychological well-being by contributing to all five component elements, (3) discussing the psychological benefits of martial arts training from the perspective of an Everlast Master Instructor, and (4) discussing how martial arts training involves the cultivation of combat-relevant affordances.
