BACKGROUND: Ethnic minorities and people with a low socio-economic status (SES) are often mentioned groups potentially affected by double stigma when faced with the burden of mental illness. Against this background we examine differences in public attitudes towards a) migrant vs. non-migrant persons with depression and b) low vs. high SES persons with depression. METHOD: Analyses are based on data of a representative cross-sectional telephone survey among the adult population in Germany (N=2013)...

Acoustic signals have the potential for transmitting information fast across distances. Rats emit ultrasonic vocalizations of two distinct classes: "22-kHz" or "alarm" calls and "50-kHz" calls. The latter comprises brief sounds in the 30-80-kHz range, whose ethological role is not fully understood. We recorded ultrasonic vocalizations from pairs of rats freely behaving in neighboring but separated arenas. 50-kHz vocalizations in this condition were tightly linked to the locomotion of the emitter at the subsecond time scale, their rate sharply increasing and decreasing prior to the onset and offset of movement respectively...

Young preschool-aged children often have difficulty thinking about the future, but tend to reason better about another person's future than their own. This benefit may reflect psychological distance from one's own emotions, beliefs, and states that may bias thinking. In adults, reasoning for others who are more socially distant (i.e., dissimilar, unfamiliar other) is associated with wiser and more adaptive reasoning. The current studies examined whether this effect of social distance could be demonstrated in young children's future thinking...

Stigmatizing attitudes toward eating disorders (EDs) may lead to reduced treatment seeking. We aimed to estimate the prevalence of stigmatizing trends and beliefs related to anorexia nervosa (AN) and bulimia nervosa (BN), and the associations with the experiential knowledge of the problem, in a large sample of Italian undergraduates. A total of 2109 participants completed an online survey including questionnaires related to stigmatizing beliefs toward AN and BN, and personal contacts with people with EDs. Undergraduates reported almost overlapping low levels of stigmatizing trends for AN and BN, apart from personal responsibility and social distance...

Rationale Current practice guidelines recommend pulmonary rehabilitation as an adjunct to standard pharmacologic therapy for individuals with moderate to severe chronic obstructive pulmonary disease (COPD). Whether pulmonary rehabilitation benefits all subjects with COPD independent of baseline disease burden is not known. Objective To test whether pulmonary rehabilitation benefits patients with COPD independent of baseline exercise capacity, dyspnea and lung function. Methods Data from a prospectively maintained database of participants with COPD enrolled in pulmonary rehabilitation at the University of Alabama at Birmingham from 1996 to 2013 was retrospectively analyzed...

We consider the diffusion of new products in social networks, where consumers who adopt the product can later "recover" and stop influencing others to adopt the product. We show that the diffusion is not described by the susceptible-infected-recovered (SIR) model, but rather by a new model, the Bass-SIR model, which combines the Bass model for diffusion of new products with the SIR model for epidemics. The phase transition of consumers from nonadopters to adopters is described by a nonstandard Kolmogorov-Johnson-Mehl-Avrami model, in which clusters growth is limited by adopters' recovery...

PURPOSE: Globally, lung cancer is the most common cancer and the leading cause of cancer death. Problematically, there is a wide variation in the management and survival for people with lung cancer and there is limited understanding of the reasons for these variations. To date, the views of health professionals across relevant disciplines who deliver such care are largely absent. The present study describes Australian health professionals' views about barriers to lung cancer care to help build a research and action agenda for improving lung cancer outcomes...

BACKGROUND: Performance-based incentives (PBIs) have garnered global attention as a promising strategy to improve healthcare delivery to vulnerable populations. However, literature gaps in the context in which an intervention is implemented and how the PBIs were developed exist. Therefore, we (1) characterized the barriers and promoters to prevention of vertical transmission of HIV (PVT) service delivery in rural Mozambique, where the vertical transmission rate is 12 %, and (2) assessed the appropriateness for a PBI's intervention and application to PVT...

The beta-adrenergic antagonist propranolol benefits some social and communication domains affected in autism spectrum disorder (ASD), and these benefits appear to be associated with increased functional connectivity (FC) in the brain during task performance. FC is implicated in ASD, with the majority of studies suggesting long distance hypo-connectivity combined with regionally specific local hyper-connectivity. The objective in the current investigation was to examine the effect of propranolol on FC at rest and determine whether ASD-specific effects exist...

The food industry is often described as having more power and influence in nutrition policymaking than nutrition professionals, scientists and other practitioners working for the public interest; yet authors often allude to this point as an assumed truth, rather than an evidence-based fact. This paper applies social network analysis techniques to provide a concise evidence-based demonstration of the food industry's capacity to influence nutrition policymaking networks in Australia. Network analysis using four rounds of data collection was undertaken, and the capacity of individual actors and occupational categories to influence policy decision makers were analysed...

BACKGROUND: Individuals with mental illness often experience stigmatization and encounter stereotypes such as being dangerous or unpredictable. To further improve measures against psychiatric stigma, it is of importance to understand its components. In this study, we attend to the step of separation between "us" and "them" in the stigma process as conceptualized by Link and Phelan. In using the belief in continuity of mental illness symptoms as a proxy for separation, we explore its associations with stereotypes, emotional responses and desire for social distance in the stigma process...

Background. Antenatal care (ANC) attendance helps pregnant women to benefit from preventive and curative services. Methods. Determinants for ANC attendance were identified through a cross-sectional survey in the Democratic Republic of Congo. Sociocultural bottlenecks were assessed via focus groups discussion of married men and women. Results. In this survey, 28 of the 500 interviewed pregnant women (5.6%) did not attend ANC services and 82.4% booked over the first trimester. The first visit is positively influenced by the reproductive age (OR: 0...

Social insects make elaborate use of simple mechanisms to achieve seemingly complex behavior and may thus provide a unique resource to discover the basic cognitive elements required for culture, i.e., group-specific behaviors that spread from "innovators" to others in the group via social learning. We first explored whether bumblebees can learn a nonnatural object manipulation task by using string pulling to access a reward that was presented out of reach. Only a small minority "innovated" and solved the task spontaneously, but most bees were able to learn to pull a string when trained in a stepwise manner...

The present study evaluated the presence of drug-free family and friends in the personal social networks of individuals seeking treatment for opioid use disorder, and the willingness of patients to bring these individuals to the treatment program to support recovery efforts. Patients at a community medication-assisted treatment program (n=355) completed a clinical survey to identify drug-free social network members. Results showed that almost all patients (98%) reported having at least one drug-free family or friend in their personal network (M=3...

Individual spatial positioning plays an important role in mediating the costs and benefits of group living, and thus shapes different aspects of animal social systems including group structure and cohesiveness. I aimed to quantify variation in individual spacing behavior and its correlates in a group of wild patas monkeys (Erythrocebus patas) living in north Cameroon. I collected data on inter-individual distances during group scans when following subject females. Individuals had longer inter-individual distances during the non-birth season than during the birth season...

Complex social networks and behaviors are difficult to observe for free-living marine species, especially those that move great distances. Using implanted acoustic transceivers to study the inter- and intraspecific interactions of sand tiger sharks Carcharias taurus, we observed group behavior that has historically been associated with higher order mammals. We found evidence strongly suggestive of fission-fusion behavior, or changes in group size and composition of sand tigers, related to five behavioral modes (summering, south migration, community bottleneck, dispersal, north migration)...

Individuals are consistently observed to be risk averse over gains and risk seeking over losses. This study examined whether increased social distance would change these behavioral patterns. To test our hypothesis, social distance was manipulated by asking the participants to make decisions either for themselves or for another person (Experiment 1), either for a known person or for an unknown person (Experiment 2), and either for a close friend or for a distant friend (Experiment 3). The results of Experiments 1 and 3 showed that increased social distance made people more risk neutral, and such an effect was stronger in the gain domain than in the loss domain...

Social network structure is a fundamental determinant of human health, from infectious to chronic diseases. However, quantitative and unbiased approaches to measuring social network structure are lacking. We hypothesized that genetic relatedness of oral commensal bacteria could be used to infer social contact between humans, just as genetic relatedness of pathogens can be used to determine transmission chains of pathogens. We used a traditional, questionnaire survey-based method to characterize the contact network of the School of Public Health at a large research university...

Numerous real-world systems can be modeled as networks. To date, most network studies have been conducted assuming stationary network characteristics. Many systems, however, undergo topological changes over time. Temporal networks, which incorporate time into conventional network models, are therefore more accurate representations of such dynamic systems. Here, we introduce a novel generalized analytical framework for temporal networks, which enables 1) robust evaluation of the efficiency of temporal information exchange using two new network metrics and 2) quantitative inspection of the temporal small-worldness...
