Excessively choosing immediate over larger future rewards, or delay discounting (DD), associates with multiple clinical conditions. Individual differences in DD likely depend on variations in the activation of and functional interactions between networks, representing possible endophenotypes for associated disorders, including alcohol use disorders. Numerous fMRI studies have probed the neural bases of DD, but investigations of large-scale networks remain scant. We addressed this gap by testing whether activation within large-scale networks during Now/Later decision-making predicts individual differences in DD...

This study examined whether peer norms for aggression within the classroom impact friendship selection, maintenance, and socialization processes related to aggression across the 1st year of secondary school (N = 1,134 students from 51 classes, Mage  = 12.66). As hypothesized, longitudinal social network analyses indicated that friendship selection and influence processes related to aggression depended on the popularity norm within the classroom (i.e., the class-level association between popularity and aggression) rather than the descriptive norm (aggregated average of aggressive behavior)...

BACKGROUND: Child maltreatment is common and has long-term consequences for affective function. Investigations of neural consequences of maltreatment have focused on the amygdala. However, developmental neuroscience indicates that other brain regions are also likely to be affected by child maltreatment, particularly in the social information processing network (SIPN). We conducted a quantitative meta-analysis to: confirm that maltreatment is related to greater bilateral amygdala activation in a large sample that was pooled across studies; investigate other SIPN structures that are likely candidates for altered function; and conduct a data-driven examination to identify additional regions that show altered activation in maltreated children, teens, and adults...

BACKGROUND: Multiple studies have compared coronary artery bypass graft (CABG) with percutaneous coronary interventions (PCI) for coronary revascularization. There is considerable evidence that adherence to medical therapy can affect the outcomes of therapeutic interventions. However, the long-term influence of compliance with recommended medical therapy on the comparative outcomes of CABG versus PCI remains to be defined. METHODS: All non-ST-segment-elevation myocardial infarction patients undergoing coronary revascularization in an 8-hospital network were followed for up to 8 years to determine medication history and major adverse cardiac events: all-cause mortality, nonfatal myocardial infarction, and reintervention...

BACKGROUND: Caring for someone with Alzheimer's disease (AD) is very challenging. Social support may play a crucial role in helping caregivers to adapt better to their caregiving role. The aim of this study is to explore the role of social support as a moderator variable of the relationship between depression and life satisfaction in caregivers for patients with AD in Saudi Arabia. METHODS: In this cross-sectional study, 122 caregivers for patients with AD completed questionnaires assessing informal social support, depressive symptoms, and general life satisfaction...

Although parents of premature infants experience many challenges when transitioning home from the neonatal intensive care unit, healthcare providers and social support systems tend to focus on mothers and infants rather than fathers. Unfortunately, very little is known about paternal concerns and needs as compared with maternal ones. The lack of understanding about paternal needs may lead to inadequate designs of neonatal intensive care unit family support programs with less involved fathers, all of which contribute to increased burdens on mothers and poor health outcomes for their infants...

Importance: Persistent postconcussion symptoms (PPCS) pose long-term challenges and can negatively affect patients' health-related quality of life (HRQoL). To date, no large comprehensive study has addressed the association between PPCS and HRQoL. Objectives: To determine the association between HRQoL and PPCS at 4 weeks after concussion and assess the degree of impairment of HRQoL in the subsequent 12 weeks. Design, Setting, and Participants: In a prospective, multicenter cohort study (Predicting Persistent Postconcussive Problems in Pediatrics [5P]) from August 14, 2013, to September 30, 2014, children aged 5 to 18 years who presented to the emergency department within 48 hours after head injury and were considered to have an acute concussion were enrolled across 9 pediatric emergency departments within the Pediatric Emergency Research Canada Network...

The dynamic of social networks is driven by the interplay between diverse mechanisms that still challenge our theoretical and modelling efforts. Amongst them, two are known to play a central role in shaping the networks evolution, namely the heterogeneous propensity of individuals to i) be socially active and ii) establish a new social relationships with their alters. Here, we empirically characterise these two mechanisms in seven real networks describing temporal human interactions in three different settings: scientific collaborations, Twitter mentions, and mobile phone calls...

Impaired cognitive empathy is a core social cognitive deficit in schizophrenia associated with negative symptoms and social functioning. Cognitive empathy and negative symptoms have also been linked to medial prefrontal and temporal brain networks. While shared behavioral and neural underpinnings are suspected for cognitive empathy and negative symptoms, research is needed to test these hypotheses. In two studies, we evaluated whether resting-state functional connectivity between data-driven networks, or components (referred to as, inter-component connectivity), predicted cognitive empathy and experiential and expressive negative symptoms in schizophrenia subjects...

Lesbian, gay, and bisexual young adults are at elevated risk for drinking compared to heterosexual young adults, and this discrepancy is particularly striking for sexual minority women (SMW). Perceived social norms are strong predictors of young adult alcohol use, especially among college students. The college environment is often one where increases in alcohol use are seen, but the impact of college status on SMW's drinking has been understudied. The present study explored patterns of alcohol use and consequences among SMW and the extent to which social norms relate to use and consequences...

With the design and development of smart cities, opportunities as well as challenges arise at the moment. For this purpose, lots of data need to be obtained. Nevertheless, circumstances vary in different cities due to the variant infrastructures and populations, which leads to the data sparsity. In this paper, we propose a transfer learning method for urban waterlogging disaster analysis, which provides the basis for traffic management agencies to generate proactive traffic operation strategies in order to alleviate congestion...

Social capital research rarely takes a gendered approach. This article explores how black women and men from a marginalized community in Johannesburg, South Africa, rely on family, friends, and community members to survive and strategize for the future by utilizing social capital. The results from 30 semi-structured interviews and ego network mapping illustrate that gender moderates the type of social capital used and benefits associated with bonding and bridging social capital in important ways. This research builds upon knowledge of gendered advantages and disadvantages in social networks and informs researchers how women and men survive in pervasive poverty...

PURPOSE: Low- and middle-income countries face a disproportionate burden of death and disability from injuries, many of which are due to road traffic accidents or falls. Lower extremity injuries in particular have implications not only for physical disabilities affecting work and school performance, but also for quality of life (QOL) of the individual. This qualitative study explores the psychosocial impact and QOL changes due to lower extremity injuries among trauma patients in central Malawi...

In 2009, India contributed to over half the global cases of poliomyelitis. Many believed that India would be the last country to be polio free. India proved them wrong and was certified polio free in 2014. In January 2016, India celebrated 5 years of being polio free. One of the major reasons behind the interruption of polio transmission in the Polio endemic states of Uttar Pradesh and Bihar was the deployment of Social Mobilization Network (SMNet). A three tiered structure, the 7300 strong SMNet is now the gold standard in public health communication...

PURPOSE: Adolescence may be a period particularly relevant for acquisition of lifelong habits of physical activity (PA). We investigated the tracking of leisure-time PA from 13 to 17 years old and the influence of urban environment and other determinants. METHODS: As part of the EPITeen cohort (Portugal), we evaluated 969 adolescents living in the city of Porto. Participants were assembled in public and private schools at 13 years and reevaluated at 17 years. Leisure-time PA was evaluated by self-reported questionnaires...

BACKGROUND: HIV testing and serostatus awareness are essential to implement biomedical strategies (treatment as prevention; oral chemoprophylaxis), and for effective serostatus-based behaviours (HIV serosorting; strategic positioning). The analysis focuses on the associations between reported sexual risks, the perceived risk for HIV infection, and HIV testing behaviour in order to identify the most relevant barriers for HIV test uptake among MSM living in Germany. METHODS: MSM were recruited to a nationwide anonymous online-survey in 2013 on MSM social networking/dating sites...

Contemporary research into health and mental health treats diagnosis as a central step in understanding illness management and trajectory; consequently, in the last two decades, sociology of diagnosis has attained increasing influence within medical sociology. Deeply embedded in social constructionism, the set of research divides between those who focus on the social and historical construction of diagnoses as categories, and those who see diagnosis as a process. Regarding the latter, this approach explores the constitution of the medical production, highlighting how it constitutes a starting point for entering a 'sick role', for being labelled, for naming one's problem and by extension, for framing one's illness narrative...
