Attitudinal acceptance of intimate partner violence (IPV) is an important correlate of violent behavior. This study examined acceptance of IPV using data collected from a nationally representative telephone survey of 5,238 adults. Multivariable logistic regression analyses were used to test for associations between sociodemographic characteristics, exposure to violence, question order, and acceptance of hitting a spouse or boyfriend/girlfriend under specific circumstances. Depending on the circumstance examined, acceptance of IPV was significantly higher among participants who were male and younger than 35; were non-White; were divorced, separated, or had never married; had not completed high school; had a low household income; or were victims of violence within the past 12 months. Participants were more accepting of women hitting men; they also were consistent’; more likely to report tolerance of IPV if they were asked first about women hitting men rather than men hitting women. Reports of IPV tolerance need to be interpreted within the context of the survey. Efforts to change IPV attitudes can be tailored to specific IPV circumstances and subgroups, and these efforts should emphasize that the use of physical violence is unacceptable to both genders.

Future research should focus on decreasing the risk of injury to linemen.

The purpose of this study was to explore and compare the attitudes towards suicidal behaviour of community mental health nurses (CMHNs) and registered nurses working in an accidents and emergency (A&E) department. The sample consisted of 80 nurses working in the same locality. An instrument was designed using statements from Domino's 'Suicide Opinion Questionnaire' (SOQ) and new statements based on a comprehensive survey of research in this area. The instrument contained four attitudinal categories consisting of; acceptability; morality and mental illness; professional role, work and care; and communication and attention. Results reveal that both groups of nurses held generally positive attitudes towards suicidal behaviour, contrasting with previous studies where more negative attitudes amongst nurses were found. A t-test showed no statistically significant differences between the two groups of nurses in any of the four attitudinal categories. Attitudes were significantly different in accordance with nurses' length of experience and age within both groups. Further research is needed in this area if nurses are to develop their role alongside other professionals working towards the objectives of suicide prevention policies.

BackgroundThe COVID-19 outbreak continues to spread internationally. After initial outbreaks have been supressed for now in China and South Korea, the virus continues to spread at an alarming rate throughout Europe. 1 At the time of writing, a quarter of the world is in some form of lockdown. We consider not just the short-term effects of COVID-19, but also medium to long-term effects. We conclude that the health system and economic impacts of COVID-19 may be exacerbated by lost opportunities for primary and secondary prevention. We suggest that in order to mitigate against this risk, public health messages are developed which are co-beneficial to protect against COVID-19 and the primary and secondary prevention of cardiovascular disease.

Spermatogenesis uses mitotic and meiotic cell cycles coordinated with growth and differentiation programs to generate functional sperm. Our analysis of a Drosophila mutant has revealed that asunder (asun), which encodes a conserved protein, is an essential regulator of spermatogenesis. asun spermatocytes arrest during prophase of meiosis I. Strikingly, arrested spermatocytes contain free centrosomes that fail to stably associate with the nucleus. Spermatocytes that overcome arrest exhibit severe defects in meiotic spindle assembly, chromosome segregation, and cytokinesis. Furthermore, the centriole-derived basal body is detached from the nucleus in asun postmeiotic spermatids, resulting in abnormalities later in spermatogenesis. We find that asun spermatocytes and spermatids exhibit drastic reduction of perinuclear dynein-dynactin, a microtubule motor complex. We propose a model in which asun coordinates spermatogenesis by promoting dynein-dynactin recruitment to the nuclear surface, a poorly understood process required for nucleus-centrosome coupling at M phase entry and fidelity of meiotic divisions.

Violent gaming induces different autonomic responses in boys compared to nonviolent gaming--during playing and during the following night--suggesting different emotional responses. Subjectively perceived sleep quality is not influenced after a single gaming experience. Future studies should address the development of the autonomic balance after gaming over longer time than a night, physiological adaptation to frequent gaming and potential gender differences.
