Bullying of lesbian, gay, bisexual, and transgender (LGBT) youth is prevalent in the United States, and represents LGBT stigma when tied to sexual orientation and/or gender identity or expression. LGBT youth commonly report verbal, relational, and physical bullying, and damage to property. Bullying undermines the well-being of LGBT youth, with implications for risky health behaviors, poor mental health, and poor physical health that may last into adulthood. Pediatricians can play a vital role in preventing and identifying bullying, providing counseling to youth and their parents, and advocating for programs and policies to address LGBT bullying...

Management of spatially structured species poses unique challenges. Despite a strong theoretical foundation, practitioners rarely have sufficient empirical data to evaluate how populations interact. Rather, assumptions about connectivity and source-sink dynamics are often based on incomplete, extrapolated, or modeled data, if such interactions are even considered at all. Therefore, it has been difficult to evaluate whether spatially structured species are meeting conservation goals. We evaluated how estimated metapopulation structure responded to estimates of population sizes and dispersal probabilities and to the set of populations included...

T Bradford Bitterly, Alison Wood Brooks, Maurice E Schweitzer
Across 8 experiments, we demonstrate that humor can influence status, but attempting to use humor is risky. The successful use of humor can increase status in both new and existing relationships, but unsuccessful humor attempts (e.g., inappropriate jokes) can harm status. The relationship between the successful use of humor and status is mediated by perceptions of confidence and competence. The successful use of humor signals confidence and competence, which in turn increases the joke teller's status. Interestingly, telling both appropriate and inappropriate jokes, regardless of the outcome, signals confidence...

Risky decision making is prominent during adolescence, perhaps contributed to by heightened sensation seeking and ongoing maturation of reward and dopamine systems in the brain, which are, in part, modulated by sex hormones. In this study, we examined sex differences in the neural substrates of reward sensitivity during a risky decision-making task and hypothesized that compared with girls, boys would show heightened brain activation in reward-relevant regions, particularly the nucleus accumbens, during reward receipt...

INTRODUCTION: Tobacco use has shifted increasingly from cigarettes to other products. While the focus has been mostly on cigarette-oriented policies, it is important to gauge the effects of policies targeting other products. We review and critique the literature on how policies affect smokeless tobacco (ST). METHODS: We conducted a search of the literature on tobacco control policies as they relate to ST use, focusing on tobacco taxes, smoke-free air laws, media campaigns, advertising restrictions, health warnings, cessation treatment policies and youth access policies...

Intergroup violence is common among humans worldwide. To assess how within-group social dynamics contribute to risky, between-group conflict, we conducted a 3-y longitudinal study of the formation of raiding parties among the Nyangatom, a group of East African nomadic pastoralists currently engaged in small-scale warfare. We also mapped the social network structure of potential male raiders. Here, we show that the initiation of raids depends on the presence of specific leaders who tend to participate in many raids, to have more friends, and to occupy more central positions in the network...

Nearly 4 years after the first report of the emergence of Middle-East respiratory syndrome Coronavirus (MERS-CoV) and nearly 1800 human cases later, the ecology of MERS-CoV, its epidemiology, and more than risk factors of MERS-CoV transmission between camels are poorly understood. Knowledge about the pathways and mechanisms of transmission from animals to humans is limited; as of yet, transmission risks have not been quantified. Moreover the divergent sanitary situations and exposures to animals among populations in the Arabian Peninsula, where human primary cases appear to dominate, vs...

HIV and AIDS are rapidly spreading amongst the world's 15- to 24-year age group, particularly in sub-Saharan Africa. Despite vigorous government interventions and campaigns, 10 % of South African youth in the age cohort 15-24 are infected with HIV and AIDS. Furthermore, for the first time in history the world has its largest number of individuals under the age of 30 years. Researchers are desperately seeking a solution and have found religion to play an important role in moderating risky sexual behaviour amongst youth...

Zimbabwe is going through a generalised acquired immunodeficiency syndrome (AIDS) epidemic. The first five years of the epidemic (1985-1990) were characterised by lack of medicines against human immunodeficiency virus (HIV), and an exponential increase in prevalence (65-fold) and incidence (13-fold), which were fuelled by high-risk sexual behaviour. The high HIV prevalence, mortality and stigma yielded great fear and panic in the population, which are thought to have led to confusion and hopelessness, and, in turn, increased risky sexual behaviour...

The doom and gloom of antibiotic resistance dominates public perception of this drug class. Many believe the world has entered the post-antibiotic era. Classic and modern approaches to antibacterial drug discovery have delivered a plethora of lead molecules with a great majority being natural products of ancient microbial origin. The failure of antibiotics in the resistance era comes from an inability to develop new leads into clinical candidates, which is a costly and risky endeavor for any therapeutic area, especially when resistance is at play...

Mental health policy includes a clear expectation that consumers will participate in all aspects of the design and delivery of mental health services. This edict has led to employment roles for people with lived experience of significant mental health challenges and service use. Despite the proliferation of these roles, research into factors impacting their success or otherwise is limited. This paper presents findings from a grounded theory study investigating the experiences of Lived Experience Practitioners in the context of their employment...

This study documents a risky vascular anatomic orientation that might play an important role in the postoperative hemodynamics following anterior cerebral artery (ACA) revascularization. A 71-year-old woman presented with uncontrollable frequent right lower limb transient ischemic attacks (TIAs) attributed to a left cerebral ischemic lesion due to severe left ACA stenosis. She underwent successful left-sided superficial temporal artery-ACA bypass using interposed vascular graft. The patient awoke satisfactory from anesthesia; however, on postoperative day 1, she developed right-sided hemiparesis...

Christopher R Madan, Elliot A Ludvig, Marcia L Spetch
People's risk preferences differ for choices based on described probabilities versus those based on information learned through experience. For decisions from description, people are typically more risk averse for gains than for losses. In contrast, for decisions from experience, people are sometimes more risk seeking for gains than losses, especially for choices with the possibility of extreme outcomes (big wins or big losses), which are systematically overweighed in memory. Using a within-subject design, this study evaluated whether this memory bias plays a role in the differences in risky choice between description and experience...

Adolescence is a developmental period characterized by a greater tendency to take risks. While the adult literature has shown that sex steroids influence reward-related brain functioning and risk taking, research on the role of these hormones during puberty is limited. In this study, we examined the relation between pubertal hormones and adolescent risk taking using a probabilistic decision-making task. In this task, participants could choose on each trial to play or pass based on explicit information about the risk level and stakes involved in their decision...

Aquatic sports are included in the top list of risky practices as the environment per se carries a possibility of death by drowning if not rescued in time. Not only are aquatic sports related to a high risk of death, but also all sports practiced on the water, over the water and on ice. Whatever the reason a person is in the water, drowning carries a higher possibility of death if the individual is unable to cope with the water situation, which may simply be caused by an inability to stay afloat and get out of the water or by an injury or disease that may lead to physical inability or unconsciousness...

Some nest predators visually assess parental activities to locate a prey nest, whereas parents modify fitness-related traits to reduce the probability of nest predation, and/or nestlings fledge early to escape the risky nest environment. Here, we experimentally tested if the parental and fledging behaviours of oriental tits (Parus minor) that bred in the nest-box varied with cavity conditions associated with nest predation risk during the nestling period. The entrance of experimental nest-boxes was enlarged to create a long-term risk soon after clutch competition...

BACKGROUND: The incidence and severity of football-related injuries has been found to differ strongly between professional leagues from different countries. The aims of this study were to record the incidence, type and severity of injuries in Kosovarian football players and investigate the relationship between injury incidence rates (IRs), players' age and playing positions. METHODS: Players' age, anthropometric characteristics and playing positions, training and match exposure as well as injury occurrences were monitored in 11 teams (143 players) of Kosovo's top division during the 2013/14 season...

Christopher M Baker, Ascelin Gordon, Michael Bode
Introducing a new, or previously extant, species to an ecosystem is a risky decision, and managers need quantitative methods that can predict the consequences for the recipient ecosystem. Proponents of keystone predator reintroductions commonly argue that the presence of the predator will restore ecosystem function, but this has not always been the case, and mathematical modeling has important role to play in predicting how reintroductions will likely play out. We propose an ensemble modeling method that integrates species interaction networks and dynamic community simulations, and use it to describe the range of plausible consequences of keystone predator reintroduction...

Despite the prevalence of the phenomena of peer victimization and bystander behaviors, little data has generated to describe their relationships and risk factors. In this paper, a self-administered survey using a cross-sectional cluster-random sampling method in a sample of 5450 participants (2734 girls and 2716 boys) between 4th and 11th grades was conducted at six schools (two primary schools and four middle schools) located in Shantou, China. Self-reported peer victimization, bystander behaviors and information regarding parents' risky behaviors and individual behavioral factors were collected...

BACKGROUND: Risky behaviors tend to increase drastically during the transition into young adulthood. This increase may ultimately facilitate the initiation of carcinogenic processes at a young age, highlighting a serious public health problem. By promoting information seeking behavior (ISB), young adults may become aware of cancer risks and potentially take preventive measures. OBJECTIVE: Based on the protection motivation theory, the current study seeks to evaluate the impact of challenge in a fully automated video game called Re-Mission on young adult college students' tendency to perceive the severity of cancer, feel susceptible to cancer, and engage in ISB...
