By exploring various cultural implications of the dildo in relation to representations of lesbian sexuality, this article seeks to examine the influences of psychoanalysis on our cultural understanding of ‘dildonics’. This examination, moreover, seeks to reread the dildo through the lens of an alternative interpretive model that relies on Donna Haraway's ‘Informatics of Domination’, or ‘the translation of the world into a problem of coding’. By shifting our attention to information theory, which emphasizes pattern and randomness over absence and presence, (...) this article shows how the dildo operates as a technological extension which mutates its lesbian user and rearticulates dildonics in post-gender terms. Such a transformation is capable of disrupting any sense that the dildo operates as a simulacral penis or as indicative of a lesbian's repressed desire for a male lover. (shrink)

The relative reinforcing value of food measures how hard someone will work for a high-energy-dense food when an alternative reward is concurrently available. Higher RRV for HED food has been linked to obesity, yet this association has not been examined in low-income preschool-age children. Further, the development of individual differences in the RRV of food in early childhood is poorly understood. This cross-sectional study tested the hypothesis that the RRV of HED to low-energy-dense food would be greater in children with (...) obesity compared to children without obesity in a sample of 130 low-income 3- to 5-year-olds enrolled in Head Start classrooms in Central Pennsylvania. In addition, we examined individual differences in the RRV of food by child characteristics and food security status. The RRV of food was measured on concurrent progressive-ratio schedules of reinforcement. RRV outcomes included the last schedule reached for cookies and fruit, the breakpoint for cookies in proportion to the total breakpoint for cookies and fruit combined, and response rates. Parents completed the 18-item food security module to assess household food security status and the Behavioral Activation System scale to assess reward sensitivity. Pearson’s correlations and mixed models assessed associations between continuous and discrete child characteristics with RRV outcomes, respectively. Two-way mixed effects interaction models examined age and sex as moderators of the association between RRV and Body Mass Index z-scores. Statistical significance was defined as p < 0.05. Children with obesity had a greater cookie Pmax [F = 4.95, p = 0.03], higher RRV cookie [F = 4.28, p = 0.04], and responded at a faster rate for cookies [F = 17.27, p < 0.001] compared to children without obesity. Children with higher cookie response rates had higher BMIZ ; and RRV cookie was positively associated with BMIZ for older children and boys, but not younger children or girls. The RRV of food did not differ by household food security status. Low-income children with obesity showed greater motivation to work for cookies than fruit compared to their peers without obesity. The RRV of HED food may be an important contributor to increased weight status in boys and future research is needed to better understand developmental trajectories of the RRV of food across childhood.

Why do humans make music? Theories of the evolution of musicality have focused mainly on the value of music for specific adaptive contexts such as mate selection, parental care, coalition signaling, and group cohesion. Synthesizing and extending previous proposals, we argue that social bonding is an overarching function that unifies all of these theories, and that musicality enabled social bonding at larger scales than grooming and other bonding mechanisms available in ancestral primate societies. We combine cross-disciplinary evidence from archeology, anthropology, (...) biology, musicology, psychology, and neuroscience into a unified framework that accounts for the biological and cultural evolution of music. We argue that the evolution of musicality involves gene–culture coevolution, through which proto-musical behaviors that initially arose and spread as cultural inventions had feedback effects on biological evolution because of their impact on social bonding. We emphasize the deep links between production, perception, prediction, and social reward arising from repetition, synchronization, and harmonization of rhythms and pitches, and summarize empirical evidence for these links at the levels of brain networks, physiological mechanisms, and behaviors across cultures and across species. Finally, we address potential criticisms and make testable predictions for future research, including neurobiological bases of musicality and relationships between human music, language, animal song, and other domains. The music and social bonding hypothesis provides the most comprehensive theory to date of the biological and cultural evolution of music. (shrink)

Abstract Christopher Gauker has argued that a cause?effect analysis of the acquisition of communication skills in chimpanzees is adequate to describe the data reported in our work at the Language Research Center. I agree that the cause?effect approach to language function is the only viable method of analyzing language. Language must be studied as a process that functions to organize behavior between two or more individuals. However, the problem of language understanding is not addressed satisfactorily by the perspective offered by (...) Gauker. Some more recent work, particularly with the pygmy chimpanzee ?Kanzi?, is now beginning to explicate a cause?effect analysis of language comprehension. It is argued that in the young chimpanzee, as with children, language comprehension is the driving force underlying the language acquisition process. It is further argued that the transition from comprehension to production is made possible by the capacity for goal?directed observational imitation. (shrink)

Bien que la dichotomie classique homme/animal continue de sous-tendre la pensée scientifique occidentale, la génétique moléculaire prouve que les humains sont bien plus proches des chimpanzés et des bonobos que ne pouvaient le supposer les chercheurs en se fondant seulement sur l’évidence anatomique, il y a quelques décennies. Le degré de similitude de l’ADN entre humains, bonobos et chimpanzés autorise à nous classer tous trois comme espèces-sœurs. Ce qui signifie, aussi étrange que cela pui..

The role of Human Research Ethics Committees (HRECs) in health research is well established. Ethics committees have the good of research participants in mind but they must also assess scientific merit including the design and conduct of studies. In this article the authors’ focus is on qualitative research method and the challenge that the National Statement on Ethical Conduct in Human Research (2007) poses for ethics committees when they assess proposals using the methods outlined in the National Statement.We set out (...) a process for judging the standard of qualitative research proposals and propose that qualitative health research can be assessed using a hierarchy designed for evaluating interview studies. We contrast well-designed studies with those that have design flaws in order to focus on the hallmarks of research merit in studies that use qualitative research methods. Finally, we show that our proposal is compatible with the National Statement.Ethics review provides an early opportunity to identify and redesign inadequate studies that will not contribute to our knowledge base. The challenge for members of ethics committees with little experience in qualitative studies is to be able to assess research excellence by assessing research merit in proposals, recognising the special design features of qualitative research methods.

We compare and contrast the 60 commentaries by 109 authors on the pair of target articles by Mehr et al. and ourselves. The commentators largely reject Mehr et al.'s fundamental definition of music and their attempts to refute (1) our social bonding hypothesis, (2) byproduct hypotheses, and (3) sexual selection hypotheses for the evolution of musicality. Instead, the commentators generally support our more inclusive proposal that social bonding and credible signaling mechanisms complement one another in explaining cooperation within and competition (...) between groups in a coevolutionary framework (albeit with some confusion regarding terminologies such as “byproduct” and “exaptation”). We discuss the proposed criticisms and extensions, with a focus on moving beyond adaptation/byproduct dichotomies and toward testing of cross-species, cross-cultural, and other empirical predictions.

The present study examined the effects of gender on the emotional responses (physiology, self-reports of emotion, and emotional facial behaviour) of European Americans (EA) and Hmong Americans (HA) while they relived past emotional events. Women were more emotionally reactive than men: They demonstrated greater changes in electrodermal reactivity overall, reported experiencing more intense emotion while reliving anger and love, and smiled more while reliving happiness and love. The pattern and magnitude of these differences were similar for EA and HA, suggesting (...) that to some degree, the effects of gender on emotional response may hold across ethnic groups. (shrink)

Human pluripotent stem cells (hPSCs) have the potential to fundamentally change the way that we go about treating and understanding human disease. Despite this extraordinary potential, these cells also have an innate capability to form tumors in immunocompromised individuals when they are introduced in their pluripotent state. Although current therapeutic strategies involve transplantation of only differentiated hPSC derivatives, there is still a concern that transplanted cell populations could contain a small percentage of cells that are not fully differentiated. In addition, (...) these cells have been frequently reported to acquire genetic alterations that, in some cases, are associated with certain types of human cancers. Here, we try to separate the panic from reality and rationally evaluate the true tumorigenic potential of these cells. We also discuss a recent study examining the effect of culture conditions on the genetic integrity of hPSCs. Finally, we present a set of sensible guidelines for minimizing the tumorigenic potential of hPSC‐derived cells. © 2016 The Authors. Inside the Cell published by Wiley Periodicals, Inc. (shrink)

A partir do ensaio (1922) de Walter Benjamin sobre as Afi nidades Eletivas de Goethe, o artigo tenta mostrar como Benjamin, desde esse ensaio de juventude até seu último texto, as teses “Sobre o conceito de história” (1940), defende uma noção de fi lologia crítica, capaz de evidenciar no detalhe material a distância histórica que separa a obra, em sua concretude histórica, do momento histórico do intérprete ou historiador. Somente o reconhecimento desse distanciamento permite não cair nas armadilhas da Einfühlung (...)

Nurses are encountering an increasing number of ethical dilemmas in clinical practice. Ethics courses for baccalaureate nursing students provide the opportunity for the development of critical thinking skills in order to deal with these effectively. The purpose of this descriptive qualitative study was to describe ethical reasoning in 70 baccalaureate nursing students enrolled in a nursing ethics course. Reflective clinical journals were analyzed as appropriate for qualitative inquiry. The overriding theme emerging from the data was `in the process of becoming', (...) which includes: practicing as a professional, lacking the confidence as a student nurse to take an ethical stand, advocating for patients, being just in the provision of care, identifying the spiritual dimensions of nursing practice, confronting the `real world' of health care, making a commitment to practice with integrity, and caring enough to care. The development of critical thinking and ethical reasoning within the framework of knowing and connecting is essential in nursing education. (shrink)
