The relationship between androgenic hormones, like testosterone (T), and aggression is extensively studied in human populations. Yet, while this work has illuminated a variety of principals regarding the behavioral and phenotypic effects of T, it is also hindered by inherent limitations of performing research on people. In these instances, animal research can be used to gain further insight into the complex mechanisms by which T influences aggression. Here, we explore recent studies on T and aggression in numerous vertebrate species, although we focus primarily on males and on a New World rodent called the California mouse (Peromyscus californicus)...

Addressing the social determinants of health (SDOH) that influence teen pregnancy is paramount to eliminating disparities and achieving health equity. Expanding prevention efforts from purely individual behavior change to improving the social, political, economic, and built environments in which people live, learn, work, and play may better equip vulnerable youth to adopt and sustain healthy decisions. In 2010, the Centers for Disease Control and Prevention in partnership with the Office of Adolescent Health funded state- and community-based organizations to develop and implement the Teen Pregnancy Prevention Community-Wide Initiative...

The aim of the study was to follow up inter-professional experiences of improvement work one year after a completed CII improvement program aiming at improve health care and social services for people with mental disabilities living in ordinary housing. This study was performed with a qualitative descriptive approach which employed six focus group interviews followed by a thematic analysis. The results revealed four themes; Self-awareness and insights; Behavior and actions in daily practice; Organizational cultures and subcultures; and Organizational practices, using Ken Wilbers' integral theory of four quadrants of realities as a holistic frame in the discussion...

This work adopts a perspective that construes acculturation as a dynamic intergroup process, and social contact with members of the new community as a key mechanism underlying cultural adaptation. We argue that migrants' initial self-reported mainstream cultural orientation constitutes an important antecedent of early social participation in the new community. Results from two longitudinal studies of newly arrived international students (N = 98 and N = 60) show that more positive initial mainstream cultural orientations prospectively predict higher social participation, specifically in the mainstream group, over the following months...

In the field of evolutionary game theory, network reciprocity has become an important means to promote the level of promotion within the population system. Recently, the interdependency provides a novel perspective to understand the widespread cooperation behavior in many real-world systems. In previous works, interdependency is often built from the direct or indirect connections between two networks through the one-to-one mapping mode. However, under many realistic scenarios, players may need much more information from many neighboring agents so as to make a more rational decision...

Why do we grow up to have the traits we do? Most 20th century scientists answered this question by referring only to our genes and our environments. But recent discoveries in the emerging field of behavioral epigenetics have revealed factors at the interface between genes and environments that also play crucial roles in development. These factors affect how genes work; scientists now know that what matters as much as which genes you have (and what environments you encounter) is how your genes are affected by their contexts...

Recent findings showed that users on Facebook tend to select information that adhere to their system of beliefs and to form polarized groups - i.e., echo chambers. Such a tendency dominates information cascades and might affect public debates on social relevant issues. In this work we explore the structural evolution of communities of interest by accounting for users emotions and engagement. Focusing on the Facebook pages reporting on scientific and conspiracy content, we characterize the evolution of the size of the two communities by fitting daily resolution data with three growth models - i...

Importance: Psychiatric comorbidity complicates clinical care and confounds efforts to elucidate the pathophysiology of commonly occurring symptoms in youths. To our knowledge, few studies have simultaneously assessed the effect of 2 continuously distributed traits on brain-behavior relationships in children with psychopathology. Objective: To determine shared and unique effects of 2 major dimensions of child psychopathology, irritability and anxiety, on neural responses to facial emotions during functional magnetic resonance imaging...

Social play behavior is a highly rewarding, developmentally important form of social interaction in young mammals. However, its neurobiological underpinnings remain incompletely understood. Previous work has suggested that opioid and endocannabinoid neurotransmission interact in the modulation of social play. Therefore, we combined behavioral, pharmacological, electrophysiological, and genetic approaches to elucidate the role of the endocannabinoid 2-arachidonoylglycerol (2-AG) in social play, and how cannabinoid and opioid neurotransmission interact to control social behavior in adolescent rodents...

Social scientists have proposed various theories as to when, why, and how people come to seek medical care for multiple conditions. Yet, there is still little empirical research to illustrate the pathways into and out of care, especially for chronic illness. This article contributes to this body of work by exploring individuals' reasons for delaying and seeking care for obstructive sleep apnea, which despite being the most diagnosed sleep disorder, has been largely neglected by social scientists. Drawing upon in-depth interviews with 65 Jewish-Israeli obstructive sleep apnea patients, this study shows how intersections of gender, family, and morality shape and are shaped by care-seeking behavior...

We compared baseline demographic characteristics, clinical features, and grief-related thoughts, feelings and behaviors of individuals bereaved by suicide, accident/homicide and natural causes participating in a complicated grief (CG) treatment clinical trial. Severity of CG and depression and current depression diagnosis did not vary by loss type. After adjusting for baseline demographic features, time since death and relationship to the deceased, those with CG after suicide had the highest rates of lifetime depression, pre-loss passive suicidal ideation, self-blaming thoughts, and impaired work and social adjustment...

Moderate exposure to alcohol during development leads to subtle neurobiological and behavioral effects classified under the umbrella term fetal alcohol spectrum disorders (FASDs). Alterations in social behaviors are a frequently observed consequence of maternal drinking, as children with FASDs display inappropriate aggressive behaviors and altered responses to social cues. Rodent models of FASDs mimic the behavioral alterations seen in humans, with rats exposed to ethanol during development displaying increased aggressive behaviors, decreased social investigation, and altered play behavior...

BACKGROUND: The relationship between sleep disorders and Internet addiction has been little work. Given the importance of these disorders, we felt it appropriate to make a synthesis of available data and to establish causality or accountability between Internet addiction and the onset of sleep disorders. METHODS: A literature review was then performed. We selected scientific articles in English and French, published between 1987 and 2016 by consulting the databases Medline, Embase, PsycINFO and Google Scholar...

Rewards have social significance and are highly esteemed objects, but what does their ownership signify to others? Prior work has demonstrated it may be possible for these rewards to spread their status to those who possess them, such that individuals gain or lose status and influence by virtue of the rewards they display. Yet, is this spread enough to produce entirely new status characteristics by virtue of their association with rewards? I propose a theoretical extension of the spread of status value theory and offer an experimental test considering whether the status value conveyed by rewards spreads to a new, nominal characteristic of those who come to possess these objects...

This article examines the influence of social context on the rate of first birth. Drawing on socialization models, I develop a theoretical framework to explain how different aspects of social context (i.e., neighbors), may affect the rate of first birth. Neighbors, who in the study setting comprise individuals' immediate social context, have an important influence on the rate of first birth. To test my hypotheses, I leverage a setting, measures and analytical techniques designed to study the impact of macro-level social contexts on micro-level individual behavior...

Neural systems that index self-regulation have been associated with mental health outcomes, including risk for anxiety problems, from early in life. Yet, little is known about the environmental factors that may impact the development of neural systems of regulation. Behavioral work suggests that sensitive parenting, or parents' ability to correctly interpret and respond to children's signals, supports the development of regulation. Conversely, harsh parenting, or uninvolved or punitive parent behaviors, is thought to compromise developing regulatory systems...

BACKGROUND: Presenteeism is a growing problem in developed countries mostly due to an aging workforce. The economic costs related to presenteeism exceed those of absenteeism and employer health costs. Employers are implementing workplace health promotion and wellness programs to improve health among workers and reduce presenteeism. How best to design, integrate and deliver these programs are unknown. The main purpose of this study was to use an intervention mapping approach to develop a workplace health promotion and wellness program aimed at reducing presenteeism...

BACKGROUND: The neuropeptide arginine vasopressin (Avp) modulates social behaviors via its two centrally expressed receptors, the Avp 1a receptor and the Avp 1b receptor (Avpr1b). Recent work suggests that, at least in mice, Avp signaling through Avpr1b within the CA2 region of the hippocampus is critical for normal aggressive behaviors and social recognition memory. However, this brain area is just one part of a larger neural circuit that is likely to be impacted in Avpr1b knockout (-/-) mice...

Previous research suggests that reputational concerns can incentivize cooperation and deter socially deviant behavior. The current research showed that social monitoring of information that has the potential to damage one's reputation has differential effects on deviant behavior in social-ecological environments that vary in level of mobility. Study 1 showed that residentially stable cities that employed more journalists-who can be regarded as social monitoring agents in a community-tended to have lower rates of violent crime than residentially stable cities that employed fewer journalists; by contrast, in residentially mobile cities, violent crime rates did not vary as a function of the number of journalists employed...
