Dance has traditionally been viewed from a Eurocentric perspective as a mode of self-expression that involves the human body moving through space, performed for the purposes of art, and viewed by an audience. In this Hypothesis and Theory article, we synthesize findings from anthropology, sociology, psychology, dance pedagogy, and neuroscience to propose The Synchronicity Hypothesis of Dance, which states that humans dance to enhance both intra- and inter-brain synchrony. We outline a neurocentric definition of dance, which suggests that dance involves (...) neurobehavioral processes in seven distinct areas including sensory, motor, cognitive, social, emotional, rhythmic, and creative. We explore The Synchronicity Hypothesis of Dance through several avenues. First, we examine evolutionary theories of dance, which suggest that dance drives interpersonal coordination. Second, we examine fundamental movement patterns, which emerge throughout development and are omnipresent across cultures of the world. Third, we examine how each of the seven neurobehaviors increases intra- and inter-brain synchrony. Fourth, we examine the neuroimaging literature on dance to identify the brain regions most involved in and affected by dance. The findings presented here support our hypothesis that we engage in dance for the purpose of intrinsic reward, which as a result of dance-induced increases in neural synchrony, leads to enhanced interpersonal coordination. This hypothesis suggests that dance may be helpful to repattern oscillatory activity, leading to clinical improvements in autism spectrum disorder and other disorders with oscillatory activity impairments. Finally, we offer suggestions for future directions and discuss the idea that our consciousness can be redefined not just as an individual process but as a shared experience that we can positively influence by dancing together.

Objectives—To assess the process involved in obtaining ethical approval for a single-centre study involving geographically dispersed subjects with an uncommon genetic disorder. Design—Observational data of the application process to 53 local research ethics committees (LRECs) throughout Wales, England and Scotland. The Multicentre Research Ethics Committee (MREC) for Wales had already granted approval. Results—Application to the 53 LRECs required 24,552 sheets of paper and took two months of the researcher's time. The median time taken for approval was 39 days with only (...) seven (13%) of committees responding within the recommended 21 days. In at least nineteen cases (36%) a subcommittee considered the application. Thirty-three committees (62%) accepted the proposal without amendments but, of the remainder, four (8%) requested changes outside of the remit of LRECs. Discussion—Difficulties still exist with the system for obtaining ethical approval for studies involving a single centre but with patients at multiple sites, as is often required for genetic observational research. As such studies differ from true multicentre studies, it may be advantageous to develop a separate and specific process of application to ensure that resources are not unnecessarily expended in the quest for ethical approval.

This empirical study concerns the authorship credit decision-making processes and outcomes that occur among coauthors in cases of multiauthored publications. The 2002 American Psychological Association (APA) Ethics Code offers standards for determining authorship order; however, little is known about how these decisions are made in actual practice. Results from a survey of 109 randomly selected authors indicated that most authors were satisfied with the decision-making process and outcome with few disagreements. Participants reported cases of both undeserved authorship being given and (...) omission of deserving contributors' names as coauthors. Some factors associated with authorship decisions included "sense of loyalty or obligation," "publish or perish pressures," and "power differentials." Authors who used APA standards were significantly more satisfied with both the process and outcome of authorship credit decisions. (shrink)
Particular visions of urban development are often codified in multi-year resource management policies. These policies, and the negotiations leading to them, are based in specific problem frames and narratives with long legacies. As conditions change and knowledge improves, there is often a need to revisit how problems, opportunities, and development pathways were defined historically, and to consider the viability of alternative pathways for development. In this article, we examine the case of agriculture near Metropolitan Phoenix, in the Central Arizona region, (...) to highlight how frames and narratives embedded in policy can reinforce particular development pathways, even as information, conditions, and values evolve. Using expert interviews and secondary data, we document alternative frames and narratives that may offer different pathways for development and sustainability in the region. By highlighting alternative narratives, we demonstrate the uncertainties and limitations associated with all narratives about development pathways, and explore the possibilities that narrative shifts can alter future outcomes.

Socioemotional selectivity theory, an influential life-span theory, suggests that older adults prefer persuasive messages that appeal to emotionally-meaningful goals over messages that appeal to knowledge-related goals, whereas younger adults do not show this preference. A mixed-factorial experiment was conducted to test whether older adults differ from younger adults in their preference for emotionally-meaningful appeals over knowledge-related appeals, when appeals are clearly developed in line with SST. For older adults we found the expected preference for emotionally-meaningful appeals for cancer centers but (...) not for grocery stores and travel organizations. As expected, in most cases, younger adults did not show a preference. Implications for SST-based communication research and for practice are discussed. (shrink)
Evidence from a University of Zimbabwe oral history project suggests that many rural women in colonial Rhodesia played an active role in undermining patriarchal customs which they experienced as oppressive. These women defied family norms by choosing their own marriage partners, prioritizing the formal education of their daughters and finding ways to generate income to secure greater degrees of autonomy. This study compliments other research which depicts women's primary form of resistance to be moving from rural to urban areas, by (...) showing what options some women exercised while remaining within rural society.

In the past few decades, awareness around gender-based violence has expanded on a global scale with increased attention in global treaties, organizations, and conferences. Previously a taboo topic, it is now viewed as a human rights violation in the broader world culture. Drawing on a quantitative analysis of 568 textbooks from 76 countries from across the world, we examine the extent to which this growing global attention to GBV has filtered down into national educational curricula. We find that textbook discussions (...) of GBV are more prevalent in the post-1993 period and are linked to discussions of women’s rights. In addition, discussions of GBV are more common in countries with more linkages to the global women’s movement. Findings from our study underscore the influence of the women’s rights movement and the radical feminist perspective on the reframing of GBV as a human rights issue. (shrink)
A theoretical framework is required that explains why and how cross-group contact reduces collective action and how the demobilizing effects can be counteracted. We propose that at least two mechanisms are involved: an affective process whereby the positive affect created offsets negative emotions and action tendencies, and a more strategic process whereby individual advancement comes to seem like a possibility.
Youths with disruptive behavior disorders and psychopathic traits showed reduced amygdala responses to fearful expressions under low attentional load but no indications of increased recruitment of regions implicated in top- down attentional control. These findings suggest that the emotional deficit observed in youths with disruptive behavior disorders and psychopathic traits is primary and not secondary to increased top- down attention to nonemotional stimulus features.
Recent research has shown that mind wandering recruits executive resources away from the external task towards inner thoughts. No studies however have determined whether executive functions are drawn away in a unitary manner during mind wandering episodes, or whether there is variation in specific functions impacted. Accordingly, we examined whether mind wandering differentially modulates three core executive functions—response inhibition, updating of working memory, and mental set shifting. In three experiments, participants performed one of these three executive function tasks and reported (...) their attentional state as either on-task or mind wandering at random intervals. We found that mind wandering led to poorer performance in the response inhibition and working memory tasks, but not the set-shifting task. These findings suggest that mind wandering does not recruit executive functions in a monolithic manner. Rather, it appears to selectively engage certain executive functions, which may reflect the adaptive maintenance of ongoing task performance. (shrink)
The ethics of Aristotle , and virtue ethics in general, have enjoyed a resurgence of interest over the past few decades. Aristotelian themes, with such issues as the importance of friendship and emotions in a good life, the role of moral perception in wise choice, the nature of happiness and its constitution, moral education and habituation, are finding an important place in contemporary moral debates. Taken together, the essays in this volume provide a close analysis of central arguments in Aristotle's (...) Nicomachean Ethics and show the enduring interest of the questions Aristotle raises.

Bringing between two covers the most influential and accessible articles on Plato's Republic, this collection illuminates what is widely held to be the most important work of Western philosophy and political theory. It will be valuable not only to philosophers, but to political theorists, historians, classicists, literary scholars, and interested general readers.
This paper uses the proxy evidence of relic inventories and labels to explore the role of relics in medieval Christianity. By means of an examination of their material nature, it argues that their primary characteristics were their fragmentary and often amorphous nature; their lack of intrinsic identification; and their easy portability. By emphasising that relic collecting was a habit that contributed to establishing religious identities and affiliations, the paper clarifies relics' role in relocating knowledge of Christian history into the homes (...) and churches of medieval Europe. Finally, having noted that their dissemination followed established networks of travel and communication, it emphasises that relics rendered the essentials of Christianity tangible and portable.

Using fractal analyses to study events allows us to capture the scale-independence of those events, that is, no matter at which level we study a phenomenon, we should get roughly the same results because events exhibit similar structure across scales. This is demonstrably true in mathematical fractals but is less assured in behavioral fractals. The current research directly tests the scale-independence hypothesis in the behavioral domain by exploring the fractal structure of aggression, a social phenomenon comprising events that span temporal (...) scales from minutes of face-to-face arguments to centuries of international armed conflicts. Using publicly available data, we examined the temporal fractal structure of four scales of aggression: wars, riots, violent crimes, and body movement during arguments. Our results lend mixed support to the scale-independence hypothesis and provide insight into the self-organization of human interactions. (shrink)
B cell activation is accompanied by metabolic adaptations to meet the increased energetic demands of proliferation. The metabolic composition of the microenvironment is known to change during a germinal center response, in inflamed tissue and to vary significantly between different organs. To sustain cellular homeostasis B cells need to be able to dynamically adapt to changes in their environment. An inability to take up and process available nutrients can result in impaired B cell growth and a diminished humoral immune response. (...) Furthermore, the metabolic microenvironment can affect B cell signaling and provide a means to avoid aberrant proliferation or modulate B cell function. Thus, a better understanding of the intricate interplay between cell signaling and metabolism could provide novel insight into how B cell function is regulated and have implications for the development of vaccines or treatment of autoimmune disorders and B cell derived malignancies. Throughout their lifespan, B cells are exposed to different metabolic environments. Signaling pathways regulating cellular responses to metabolic stress not only help to maintain B cell viability and to facilitate cellular functions but may also play an important role in preventing excessive proliferation and malignant transformation.
