BACKGROUND: Despite prevention efforts, the incidence of sexually transmitted infection among HIV-positive men who have sex with men remains high, which is indicative of unchanged sexual risk behaviour. Discussing sexual risk behaviour has been shown to help prevent sexually transmitted infections among HIV-positive men who have sex with men. OBJECTIVES: The aim of this study was to identify factors that influence whether - and how - specialised HIV nurses discuss sexual risk behaviour with HIV-positive men who have sex with men...

BACKGROUND: Breastfeeding competencies are not standardized in healthcare education for any of the health professions. A few continuing education/professional development programs have been implemented, but research regarding the efficacy of these programs is scarce. Research aim: After a 45-hour lactation course, (a) Does breastfeeding knowledge increase? (b) Do beliefs and attitudes about infant feeding improve? (c) Does perceived behavioral control over performance of evidence-based lactation support practices increase? and (d) Do intentions to carry out evidence-based lactation support practices increase? METHODS: A nonexperimental pretest-posttest self-report survey design was conducted with a nonprobability sample of participants ( N = 71) in a lactation course...

While eye movements were recorded and brains scanned, 29 children with and without specific learning disabilities (SLDs) decided if sentences they read (half with only correctly spelled words and half with homonym foils) were meaningful. Significant main effects were found for diagnostic groups (non-SLD control, dysgraphia control, and dyslexia) in total fixation (dwell) time, total number of fixations, and total regressions in during saccades; the dyslexia group had longer and more fixations and made more regressions in during saccades than either control group...

The major limitations with large and complex self-amplifying RNA vaccines (RepRNA) are RNase-sensitivity and inefficient translation in dendritic cells (DCs). Condensing RepRNA with polyethylenimine (PEI) gave positive in vitro readouts, but was largely inferior to virus-like replicon particles (VRP) or direct electroporation. In the present study, we improved such polyplex formulation and determined that fine-tuning of the polyplex structure is essential for ensuring efficacious translation. Thereby, three parameters dominate: (i) PEI molecular weight (MW); (ii) RepRNA:PEI (weight:weight) ratio; and (iii) inclusion of cell penetrating peptides (CPPs)...

The aim of the research was to gain increased knowledge regarding the sexual risk behaviour of school-going young people in South Africa after two decades of HIV-education in schools, to contribute to the development of improved HIV prevention strategies. In collaboration with the Department of Education, a sample of 5305 learners (between 10 and 18 years in Grades 5-12) from high-risk communities were identified. They completed a survey that assessed self-reported sexual risk behaviour and variables that potentially underlie sexual risk, such as attitudes towards preventive behaviour, perceived social norms and self-efficacy (based on the theory of planned behaviour [TPB]) and social factors like caregiver relationships and gender norms (based on the social ecological theory)...

As high-volume hydraulic fracturing (HF) has grown substantially in the United States over the past decade, so has the volume of produced water (PW), i.e., briny water brought to the surface as a byproduct of oil and gas production. According to a recent study (Groundwater Protection Council, 2015), more than 21 billion barrels of PW were generated in 2012. In addition to being high in TDS, PW may contain hydrocarbons, PAH, alkylphenols, naturally occurring radioactive material (NORM), metals, and other organic and inorganic substances...

Cooperation is a fundamental drive of moral behavior from infancy, yet competitive intergroup contexts can exert a significant influence on resource allocation behavior in childhood. The present study explored how ingroup and outgroup norms of competition and cooperation influenced the allocation of resources between groups among children and adolescents, along with how they reasoned about these allocations. Ingroup norms combined, for the first time, with outgroup norms were manipulated to examine their effect on the development of intergroup resource allocation...

Purpose While critical approaches have enriched research in proximate fields, their impact has been less marked in studies of healthcare management. In response, the 2016 Organizational Behaviour in Health Care Conference hosted its first-ever session dedicated to the emergent field of critical healthcare management studies (CHMSs). The purpose of this paper is to present five papers selected from that conference. Design/methodology/approach In this introductory paper, the authors frame the contributions as "green shoots" in a field of CHMS which contains four main furrows of activity: questioning the taken-for-granted; moving beyond instrumentalism; reflexivity and meanings in research; and challenging structures of domination (Kitchener and Thomas, 2016)...

Consistent disparities in influenza (flu) vaccine uptake among African Americans, coupled with a disproportionate burden of chronic diseases, places too many African Americans at high risk for complications, hospitalizations and premature mortality. This disparity is the result of individual attitudes and beliefs, social norms, and health care practices. Recent research identifies critical factors affecting vaccine uptake among African American adults including perceived risk of vaccine side effects, social norms that do not support for vaccination, and lower knowledge of the flu and the vaccine...

OBJECTIVE: Alcohol media literacy (AML) programs have achieved positive results for alcohol prevention; however, gender may moderate program effectiveness. This study investigated gender differences for an Australian AML intervention. METHOD: Fifth and sixth graders ( N = 165), allocated to an intervention or wait-list control group, participated in an AML program. Student questionnaires were administered at three time points. RESULTS: The intervention resulted in significantly higher media deconstruction skills but did not lead to less preference for branded merchandise or greater understanding of persuasive intent, and these effects did not differ by gender...

A new constant [Formula: see text] is introduced into any real [Formula: see text]-dimensional symmetric normed space X. By virtue of this constant, an upper bound of the geometric constant [Formula: see text], which is used to measure the difference between Birkhoff orthogonality and isosceles orthogonality, is obtained and further extended to an arbitrary m-dimensional symmetric normed linear space ([Formula: see text]). As an application, the result is used to prove a special case for the reverse Hölder inequality...

With its transparent orthography, Standard Indonesian is spoken by over 160 million inhabitants and is the primary language of instruction in education and the government in Indonesia. An assessment battery of reading and reading-related skills was developed as a starting point for the diagnosis of dyslexia in beginner learners. Founded on the International Dyslexia Association's definition of dyslexia, the test battery comprises nine empirically motivated reading and reading-related tasks assessing word reading, pseudoword reading, arithmetic, rapid automatized naming, phoneme deletion, forward and backward digit span, verbal fluency, orthographic choice (spelling), and writing...

Social norms are an important element in explaining how humans achieve very high levels of cooperative activity. It is widely observed that, when norms can be enforced by peer punishment, groups are able to resolve social dilemmas in prosocial, cooperative ways. Here we show that punishment can also encourage participation in destructive behaviours that are harmful to group welfare, and that this phenomenon is mediated by a social norm. In a variation of a public goods game, in which the return to investment is negative for both group and individual, we find that the opportunity to punish led to higher levels of contribution, thereby harming collective payoffs...
