An overview discusses (a) the importance of rape attitudes, (b) the major rape attitude measures, and (c) the applicability of four theoretical frameworks of hostility toward women to rape attitude maintenance. Findings from 72 studies of rape attitudes and individual differences were quantitatively synthesized. The meta-analysis revealed more rape acceptance for men, older people, and people from lower socioeconomic status backgrounds. For men, cognitive predispositions toward perpetrating rape were strong predictors of rape acceptance. For women, experience as and exposure to rape victims were associated with slightly less rape acceptance. Consistent with some theoretical predictions, traditional gender role beliefs, adversarial sexual beliefs, needs for power and dominance, aggressiveness and anger, and conservative political beliefs predicted rape acceptance. Implications for rape education programs and research are discussed.

Background As a priority group, healthcare personnel (HCP) will be key to success of COVID-19 vaccination programs. The purpose of this study was to assess HCP willingness to get vaccinated and identify specific concerns that would undermine vaccination efforts. Methods We conducted a cross-sectional survey of HCP, including clinical and non-clinical staff, researchers, and trainees between November 23 rd ,2020 and December 5 th ,2020. The survey evaluated attitudes, beliefs and willingness to get vaccinated. Results A total of 5287 respondents had a mean age of 42.5 years (SD=13.56), and were 72.8% female (n=3842). Overall 57.5 % of individuals expressed intent to receive COVID-19 vaccine. 80.4% were physicians and scientists representing the largest group. 33.6% of registered nurses, 31.6% of allied health professionals, and 32% of master’s level clinicians were unsure they would take the vaccine (p<.001). Respondents who were older, males, White, or Asian were more likely to get vaccinated compared to other groups. Vaccine safety, potential adverse events, efficacy and speed of vaccine development dominated concerns listed by participants. Fewer (54.0%) providers of direct care vs. non-care providers (62.4%), and 52.0% of those who had provided care for COVID-19 patients (vs. 60.6% of those who had not) indicated they would take the vaccine if offered (p<.001). Conclusions We observed that self-reported willingness to receive vaccination against COVID-19 differs by hospital roles, with physicians and research scientists showing the highest acceptance. These findings highlight important heterogeneity in personal attitudes among HCPs around COVID-19 vaccines and highlight a need for tailored communication strategies.

BackgroundDengue viruses are a major cause of morbidity in tropical and subtropical regions of the world. Inapparent dengue is an important component of the overall burden of dengue infection. It provides a source of infection for mosquito transmission during the course of an epidemic, yet by definition is undetected by health care providers. Previous studies of inapparent or subclinical infection have reported varying ratios of symptomatic to inapparent dengue infection.Methodology/Principal FindingsIn a prospective study of school children in Northern Thailand, we describe the spatial and temporal variation of the symptomatic to inapparent (S:I) dengue illness ratio. Our findings indicate that there is a wide fluctuation in this ratio between and among schools in a given year and within schools over several dengue seasons. The most important determinants of this S:I ratio for a given school were the incidence of dengue infection in a given year and the incidence of infection in the preceding year. We found no association between the S:I ratio and age in our population.Conclusions/SignificanceOur findings point to an important aspect of virus-host interactions at either a population or individual level possibly due to an effect of heterotypic cross-reactive immunity to reduce dengue disease severity. These findings have important implications for future dengue vaccines.

These findings support a pathogenesis model where cross-reactive antibodies wane from higher-titer, protective levels to lower-titer, detrimental levels. This is one of the first studies of human subjects to suggest a window of cross-protection following DENV infection since Sabin's challenge studies in the 1940s.

Abstract. Dengue virus (DENV) infection is a worsening global health problem. The plaque reduction neutralization test (PRNT) is currently considered to be the "gold standard" to characterize and quantify circulating levels of anti-DENV neutralizing antibody (NAb). Many variations of the PRNT are currently in use and neither the assay nor its performance conditions have been standardized or harmonized between laboratories. We used a well-characterized panel of acute and late convalescent follow-up sera samples from children experiencing primary and secondary DENV infections to evaluate the performance of the dengue PRNT under a variety of testing conditions. Investigators varied cell type, control virus passage, and the use of complement across multiple assay runs of the same sample panel. Our findings indicate wide variation in PRNT titer results in response to varied testing conditions.

A general framework for studying affective aggression, integrating many insights from previous models (e.g., those of Baron, Berkowitz, Geen, and Zillmann), is presented. New research examining effects of extreme temperatures and photos of guns on arousal, cognition, and affect is reported. Hostile cognition was assessed using an automatic priming task (i.e., Stroop interference). Hostile affect was assessed with the State Hostility Scale. Positive and negative affect, hostile attitudes, perceived comfort, and perceived arousal were also assessed. As expected, hot and cold temperatures increased state hostility and hostile attitudes, and viewing guns did not. As expected, viewing guns primed hostile cognitions and extreme temperatures did not. Theoretical implications of these results and societal implications of the general framework are discussed.
