Extramarital partnerships exacerbate high HIV prevalence rates in many communities in sub-Saharan Africa. We explored contextual risk factors and suggested interventions to reduce extramarital partnerships among couples in the fishing communities on Lake Victoria, Kenya. We conducted 12 focus group discussions with 9-10 participants each (N = 118) and 16 in-depth interviews (N = 16) with fishermen and their spouses. Couples who participated were consented and separated for simultaneous gender-matched discussions/interviews...

The solid state photolysis of sodium, silver and thallium hyponitrite (M2N2O2, M=Na, Ag, Tl) salts and a binuclear complex of cobalt bridged by hyponitrite ([Co(NH3)5-N(O)-NO-Co(NH3)5](4+)) were studied by irradiation with visible and UV light in the electronic absorption region. The UV-visible spectra for free hyponitrite ion and binuclear complex of cobalt were interpreted in terms of Density Functional Theory calculations in order to explain photolysis behavior. The photolysis of each compound depends selectively on the irradiation wavelength...

Theoretical accounts suggest that an alteration in the brain's learning mechanisms might lead to overhasty inferences, resulting in psychotic symptoms. Here, we sought to elucidate the suggested link between maladaptive learning and psychosis. Ninety-eight healthy individuals with varying degrees of delusional ideation and hallucinatory experiences performed a probabilistic reasoning task that allowed us to quantify overhasty inferences. Replicating previous results, we found a relationship between psychotic experiences and overhasty inferences during probabilistic reasoning...

Why do people judge hypocrites, who condemn immoral behaviors that they in fact engage in, so negatively? We propose that hypocrites are disliked because their condemnation sends a false signal about their personal conduct, deceptively suggesting that they behave morally. We show that verbal condemnation signals moral goodness (Study 1) and does so even more convincingly than directly stating that one behaves morally (Study 2). We then demonstrate that people judge hypocrites negatively-even more negatively than people who directly make false statements about their morality (Study 3)...

Early-life stress is associated with increased vulnerability to physical and emotional health problems across the lifespan. The recently developed neuroimmune network hypothesis proposes that one of the underlying mechanisms for these associations is that early-life stress amplifies bidirectional crosstalk between the brain and the immune system, contributing to several mental and physical health conditions that have inflammatory underpinnings, such as depression and coronary heart disease. Neuroimmune crosstalk is thought to perpetuate inflammation and neural alterations linked to early-life stress exposure, and also foster behaviors that can further compromise health, such as smoking, drug abuse and consumption of high-fat diets...

Metal-air batteries are intensively studied because of their high theoretical energy storage capability. However, the fundamental science at work dealing with electrodes, electrolytes and reaction products still need to be better understood. In this report, the ionic liquid N-butyl-N-methylpyrrolidinium bis(trifluoromethanesulfonyl) imide (PYR14TFSI) is chosen to study the influence of a wide range of metal cations (Mn+) on the electrochemical behavior of oxygen.. We demonstrate the relevance of the Lewis hard-soft acid-base (HSAB) theory to predict satisfactorily the reduction potential of the oxygen reduction in electrolytes containing metal cations...

Simon A Moss, Samuel G Wilson
Socioemotional selectivity theory assumes that older individuals tend to perceive their identity or life as limited in time and, therefore, prioritize meaningful relationships. Yet, other research shows that people who perceive their identity as limited in time tend to behave impulsively-contrary to the behavior of many older individuals. To redress this paradox, this article reports a systematic review, comprising 86 papers, that examined the consequences of whether individuals perceive their identity as limited or enduring...

To investigate the role of tachysterol in the photophysical/photochemical regulation of vitamin D photosynthesis, we studied its electronic absorption properties and excited state dynamics using time-dependent density functional theory (TDDFT), second-order approximate coupled cluster theory (CC2), and non-adiabatic surface hopping molecular dynamics in the gas phase. In excellent agreement with experiments, the simulated electronic spectrum shows a broad absorption band with a remarkably higher extinction coefficient than the other vitamin D photoisomers provitamin D, lumisterol, and previtamin D...

Evolutionary medicine represents an innovative approach deriving from evolutionary biology. It includes the initial Darwin's view, its actualization in the light of progresses in genetics and also dissident theories (i.e. non gene-based) particularly epigenetics. This approach enables us to reconsider the pathophysiology of numerous diseases, as for instance, infection, and our so-called diseases of civilization especially obesity, type 2 diabetes, allergy or cancer. Evolutionary medicine may also improve our knowledge regarding inter-individual variation in susceptibility to disease or drugs...

BACKGROUND: In Australia, screening for colorectal cancer (CRC) with colonoscopy is meant to be reserved for people at increased risk, however, currently there is a mismatch between individuals' risk of CRC and the type of CRC screening they receive. This paper describes the development and optimisation of a Colorectal cancer RISk Prediction tool ('CRISP') for use in primary care. The aim of the CRISP tool is to increase risk-appropriate CRC screening. METHODS: CRISP development was informed by previous experience with developing risk tools for use in primary care and a systematic review of the evidence...

Jan R Wessel, Adam R Aron
Unexpected events are part of everyday experience. They come in several varieties-action errors, unexpected action outcomes, and unexpected perceptual events-and they lead to motor slowing and cognitive distraction. While different varieties of unexpected events have been studied largely independently, and many different mechanisms are thought to explain their effects on action and cognition, we suggest a unifying theory. We propose that unexpected events recruit a fronto-basal-ganglia network for stopping...

Cognitive models of posttraumatic stress disorder (PTSD) place an emphasis on the role of negative appraisals of traumatic events. It is suggested that the way in which the event is appraised determines the extent to which posttraumatic stress symptoms will be experienced. Therefore, a strong relationship between trauma appraisals and symptoms of PTSD might be expected. However, this relationship is not as firmly established in the child and adolescent literature. A systematic literature review of this relationship returned 467 publications, of which 11 met full eligibility criteria...

Intense spiking response of a memory-pattern is believed to play a crucial role both in normal learning and pathology, where it can create biased behavior. We recently proposed a novel model for memory amplification where the simultaneous two-fold increase of all excitatory (AMPAR-mediated) and inhibitory (GABAAR-mediated) synapses in a sub-group of cells that constitutes a memory-pattern selectively amplifies this memory. Here we confirm the cellular basis of this model by validating its major predictions in four sets of experiments, and demonstrate its induction via a whole-cell transduction mechanism...

One outstanding difference between Homo sapiens and other mammals is the ability to perform highly complex cognitive tasks and behaviors, such as language, abstract thinking, and cultural diversity. How is this accomplished? According to one prominent theory, cognitive complexity is proportional to the repetition of specific computational modules over a large surface expansion of the cerebral cortex (neocortex). However, the human neocortex was shown to also possess unique features at the cellular and synaptic levels, raising the possibility that expanding the computational module is not the only mechanism underlying complex thinking...

Upon graduation, students studying in departments related to health will work in the health sector and will guide and enlighten people with their knowledge and behavior. The purpose of this study was to determine the factors affecting the physical activity (PA) conditions of university students on a health sciences campus. A cross-sectional study was carried out on 706 students in a Turkish university. The data was obtained from a survey prepared by the researchers. The 26-question survey aimed to discover the students' socio-demographic characteristics and their awareness and practices concerning PA...

Cyberbullying is a common byproduct of the digital revolution with serious consequences to victims. Unfortunately, there is a dearth of empirically based methods to confront it. This study used social cognitive theory to design and test an intervention message aimed at persuading college students to abstain from retaliation, seek social support, save evidence, and notify authorities-important victim responses identified and recommended in previous research. Using a posttest-only control group design, this study tested the effectiveness of an intervention message in changing college students' perceived susceptibility to and perceived severity of cyberbullying as well as their self-efficacy, response efficacy, attitudes, and behavioral intentions toward each recommended response in future episodes of cyberbullying...

Grounded on research showing that peer crowds vary in risk behavior, several recent health behavior interventions, including the US Food and Drug Administration's Fresh Empire campaign, have targeted high-risk peer crowds. We establish the scientific foundations for using this approach. We introduce peer crowd targeting as a strategy for culturally targeting health behavior interventions to youths. We use social identity and social norms theory to explicate the theoretical underpinnings of this approach. We describe Fresh Empire to demonstrate how peer crowd targeting functions in a campaign and critically evaluate the benefits and limitations of this approach...

Here we report on the ion conductance through individual, small diameter single-walled carbon nanotubes. We find that they are mimics of ion channels found in natural systems. We explore the factors governing the ion selectivity and permeation through single-walled carbon nanotubes by considering an electrostatic mechanism built around a simplified version of the Gouy-Chapman theory. We find that the single-walled carbon nanotubes preferentially transported cations and that the cation permeability is size-dependent...

BACKGROUND: Unprofessional behavior is a significant problem throughout graduate medical education programs and medical centers. Some authors have suggested that professionalism curricula should be focused toward faculty, not trainees, to interrupt the modeling of unprofessionalism. Developing such curricula requires a needs assessment and is challenging given data indicating that the definition of professionalism varies based on medical specialty. Thus, a specialty-specific definition of professionalism is needed as a first step in any curriculum development...
