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)

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)

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.

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)

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)

We present evidence indicating new individual differences with people's intuitions about the relation of determinism to freedom and moral responsibility. We analysed participants' written explanations of why a person acted. Participants offered one of either 'decision' or 'causal' based explanations of behaviours in some paradigmatic cases. Those who gave causal explanations tended to have more incompatibilist intuitions than those who gave decision explanations. Importantly, the affective content of a scenario influenced the type of explanation given. Scenarios containing highly affective actions (...) (e.g. murder) tended to generate more decision explanations than scenarios with low affective content (e.g. cheating on taxes). These results give important clues about the proximal processes generating some intuitions about free will and moral responsibility. (shrink)

The Birkhoff-Maltsev problem asks for a characterization of those lattices each of which is isomorphic to the lattice L(K) of all subquasivarieties for some quasivariety K of algebraic systems. The current status of this problem, which is still open, is discussed. Various unsolved questions that are related to the Birkhoff-Maltsev problem are also considered, including ones that stem from the theory of propositional logics.

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.

Through case studies that highlight the type of information that is seldom reported in the news, Faces of Environmental Racism exposes the type and magnitude of environmental racism, both domestic and international. The essays explore the justice of current environmental practices, asking such questions as whether cost-benefit analysis is an appropriate analytic technique and whether there are alternate routes to sustainable development in the South.

Since its development in the middle of the 20th century, H.L.A. Hart’s oeuvre has become a beacon for the jurisprudential community. Hart turned out to be a giant on whose shoulders many have stood. Yet the significance in its own right of Hart’s work has been neglected in recent years because his work has too often been discussed in the context of the Hart-Dworkin-debate. Hopefully, Nicola Lacey’s recent biography of Hart,which is discussed in this review-article, will contribute to redress this (...) omission. Three aspects of the biography are discussed here: 1) Hart’s life; 2) the relation between his life and work; 3) his academic work. (shrink)

Are racial slurs always offensive and are racial stereotypes always negative? How, if at all, are racial slurs and stereotypes different and unequal for members of different races? Questions like these and others about slurs and stereotypes have been the focus of much research and hot debate lately, and in a recent article Embrick and Henricks (2013) aimed to address some of the aforementioned questions by investigating the use of racial slurs and stereotypes in the workplace. Embrick and Henricks (2013) (...) drew upon the empirical data they collected at a baked goods company in the southwestern United States to argue that racial slurs and stereotypes function as symbolic resources that exclude minorities but not whites from opportunities or resources and that racial slurs and stereotypes are necessarily considered as negative or derogatory irrespective of their particular context of use (pp. 197–202). They thus proposed an account of slurs and stereotypes that supports the context-insensitive position of Fitten (1993) and Hedger (2013) yet challenges the context-sensitive position of Kennedy (2002) and Croom (2011). In this article I explicate the account of racial slurs and stereotypes provided by Embrick and Henricks (2013), outline 8 of their main claims, and then critically evaluate these claims by drawing upon recent empirical evidence on racial slurs (both in-group and out-group uses) and stereotypes (for both whites and blacks) to point out both strengths and weaknesses of their analysis. Implications of the present analysis for future work on slurs and stereotypes will also be discussed. (shrink)

Using fMRI, we investigated how right temporal lobe gliomas affecting the posterior superior temporal sulcus alter neural processing observed during speech perception and production tasks. Behavioural language testing showed that three pre-operative neurosurgical patients with grade 2, grade 3 or grade 4 tumours had the same pattern of mild language impairment in the domains of object naming and written word comprehension. When matching heard words for semantic relatedness (a speech perception task), these patients showed under-activation in the tumour infiltrated right (...) superior temporal lobe compared to 61 neurotypical participants and 16 patients with tumours that preserved the right postero-superior temporal lobe, with enhanced activation within the (tumour-free) contralateral left superior temporal lobe. In contrast, when correctly naming objects (a speech production task), the patients with right postero-superior temporal lobe tumours showed higher activation than both control groups in the same right postero-superior temporal lobe region that was under-activated during auditory semantic matching. The task dependent pattern of under-activation during the auditory speech task and over-activation during object naming was also observed in eight stroke patients with right hemisphere infarcts that affected the right postero-superior temporal lobe compared to eight stroke patients with right hemisphere infarcts that spared it. These task-specific and site-specific cross-pathology effects highlight the importance of the right temporal lobe for language processing and motivate further study of how right temporal lobe tumours affect language performance and neural reorganisation. These findings may have important implications for surgical management of these patients, as knowledge of the regions showing functional reorganisation may help to avoid their inadvertent damage during neurosurgery.

Given its non-invasive nature, there is increasing interest in the use of transcutaneous vagus nerve stimulation across basic, translational and clinical research. Contemporaneously, tVNS can be achieved by stimulating either the auricular branch or the cervical bundle of the vagus nerve, referred to as transcutaneous auricular vagus nerve stimulation and transcutaneous cervical VNS, respectively. In order to advance the field in a systematic manner, studies using these technologies need to adequately report sufficient methodological detail to enable comparison of results between (...) studies, replication of studies, as well as enhancing study participant safety. We systematically reviewed the existing tVNS literature to evaluate current reporting practices. Based on this review, and consensus among participating authors, we propose a set of minimal reporting items to guide future tVNS studies. The suggested items address specific technical aspects of the device and stimulation parameters. We also cover general recommendations including inclusion and exclusion criteria for participants, outcome parameters and the detailed reporting of side effects. Furthermore, we review strategies used to identify the optimal stimulation parameters for a given research setting and summarize ongoing developments in animal research with potential implications for the application of tVNS in humans. Finally, we discuss the potential of tVNS in future research as well as the associated challenges across several disciplines in research and clinical practice. (shrink)

This article presents the results of an experiment that completely measures the utility function and probability weighting function for different positive and negative monetary outcomes, using a representative sample of N = 1,935 from the general public. The results confirm earlier findings in the lab, suggesting that utility is less pronounced than what is found in classical measurements where expected utility is assumed. Utility for losses is found to be convex, consistent with diminishing sensitivity, and the obtained loss-aversion coefficient of (...) 1.6 is moderate but in agreement with contemporary evidence. The estimated probability weighting functions have an inverse-S shape and they imply pessimism in both domains. These results show that probability weighting is also an important phenomenon in the general population. Women and lower educated individuals are found to be more risk averse, in agreement with common findings. In contrast to previous studies that ascribed gender differences in risk attitudes solely to differences in the degree utility curvature, however, our results show that this finding is primarily driven by loss aversion and, for women, also by a more pessimistic psychological response toward the probability of obtaining the best possible outcome.

An ethics of imitation risks trivializing, aggrandizing, and homogenizing the company of disciples. Should followers of Jesus even try to walk this way?

This paper considers the prospect of moral transhumanism from the perspective of theological virtue ethics. I argue that the pursuit of goodness inherent to moral transhumanism means that there is a compelling prima facie case for moral enhancement. However, I also show that the proposed enhancements would not by themselves allow us to achieve a life of virtue, as they appear unable to create or enhance prudence, the situational judgement essential for acting in accordance with virtue. I therefore argue that (...) moral enhancement technologies should take a limited or supporting role in moral development, which I call ‘moral supplementation’. (shrink)

Much attention has been given to determining whether an adolescent patient has the capacity to consent to research. This study explores the factors that influence adolescents' decisions to participate in a research study about youth violence and to determine positive or negative feelings elicited by being a research subject. The majority of subjects perceived their decision to participate to be free of coercion, and few felt badly about having participated. However, adolescents who were alone in the room during the assent (...) process were more likely to report that they chose freely to be a research subject. This study may influence the ways physicians communicate with adolescent patients around research assent within a clinical care environment. 1This article was presented at the Annual Meetings of The Pediatric Academic Societies in Baltimore, MD and The Society for Academic Emergency Medicine in Atlanta, GA in May, 2001.
