Impact of Relationship Context on Evaluations of the Sexual Behavior of Men and Women

A number of gender differences have been found in early studies of human sexuality with males following more permissive norms for engagement in sexual behavior. More recently, male and female sexual behavior has become more similar, although literature examining attitudes towards sexual behavior has found mixed support for the idea that similar standards were used to evaluate men and women. This study examined the potential moderating roles of relationship context and traditional gender role adherence on evaluations of sexual behavior among 307 undergraduates at a public Southeastern university. Both men and women having sex within committed relationships were vieas more likeable, but men having sex in committed and women having sex in uncommitted relationships were vieas higher on diplomacy, potentially being vieas having greater integrity for not following gender norms. Traditional gender role adherence was not related to evaluations of sexual behavior. Implications are discussed

Identifying Dysfunction in Persistent Social Deviance: Perspective Taking as a Mediator of the Relationship Between Psychopathy and Social Aggression

Psychopathy has been associated with social aggression in a number of studies. Perspective taking (e.g. theory of mind and empathy) has been inversely associated with both psychopathy and social aggression, suggesting that it may serve as a potential mediator of this relationship. Structural equation modeling (SEM) was used to assess perspective taking as a potential partial mediator of the relationship between psychopathy and social aggression in a sample of 439 undergraduates. Although bivariate correlations produced the expected negative relationships between perspective taking and psychopathy and social aggression, perspective taking did not function as a mediator in the SEM analysis. Implications for future research and conceptualizations of psychopathic mechanisms of dysfunction are discussed

Improving the Quality of the Ion Beam Exiting a Quadrupole Ion Guide

The effect of fringing fields on the divergence of the ion beam exiting an RF quadrupole ion guide was studied using a computer simulation. It was shown that reducing the strength of the RF field towards the ion guide exit reduces ion beam divergence. Further improvement was demonstrated when creating a DC gradient towards the exit. The results of the numerical simulation were verified experimentally using a time-of-flight (TOF) mass analyzer with orthogonal acceleration. Decreasing the ion beam divergence resulted in considerably improved mass resolution of the instrument

Apocytochrome c

The cytochrome c import pathway differs markedly from the general route taken by the majority of other imported proteins, which is characterized by the import involvement of namely, surface receptors, the general insertion protein (GIP), contact sites and by the requirement of a membrane potential (Δψ). Unique features of both the cytochrome c precursor (apocytochrome c) and of the mechanism that transports it into mitochondria, have contributed to the evolution of a distinct import pathway that is not shared by any other mitochondrial protein analysed thus far. The cytochrome c pathway is particularly unique because i) apocytochrome c appears to have spontaneous membrane insertion-activity; ii) cytochrome c heme lyase seems to act as a specific binding site in lieu of a surface receptor and; iii) covalent heme addition and the associated refolding of the polypeptide appears to provide the free energy for the translocation of the cytochrome c polypeptide across the outer mitochondrial membrane

Changing behaviour: Increasing the effectiveness of workplace interventions in creating pro-environmental behaviour change

There is a great deal of research outlining interventions to increase pro-environmental behaviour, many of which are aimed at employees. However, to date the results for these have not lived up to their initial promise. Instead of offering another intervention, we propose a model which identifies psychological conditions under which these interventions are most likely to succeed. Through the integration of previously separate literatures from experimental social psychology, organisational psychology, organisational behaviour and environmental psychology, we suggest that the degree to which the intervention-related goal is efficacious and attractive, self-concordant, in conflict with other goals, and perceived to be completed will affect the level and type of behaviour change. Our model aims to provide actionable knowledge that extends our understanding of the effectiveness of workplace interventions designed to increase green organisational behaviour

Impact of renin-angiotensin system inhibitors on mortality during the COVID Pandemic among STEMI patients undergoing mechanical reperfusion : Insight from an international STEMI registry

Background: Concerns have been raised on a potential interaction between renin-angiotensin system inhibitors (RASI) and the susceptibility to coronavirus disease 2019 (COVID-19). No data have been so far reported on the prognostic impact of RASI in patients suffering from ST-elevation myocardial infarction (STEMI) during COVID-19 pandemic, which was the aim of the present study. Methods: STEMI patients treated with primary percutaneous coronary intervention (PPCI) and enrolled in the ISACS-STEMI COVID-19 registry were included in the present sub-analysis and divided according to RASI therapy at admission. Results: Our population is represented by 6095 patients, of whom 3654 admitted in 2019 and 2441 in 2020. No difference in the prevalence of SARSCoV2 infection was observed according to RASI therapy at admission (2.5% vs 2.1%, p = 0.5), which was associated with a significantly lower mortality (adjusted OR [95% CI]=0.68 [0.51 & ndash;0.90], P = 0.006), confirmed in the analysis restricted to 2020 (adjusted OR [95% CI]=0.5[0.33 & ndash;0.74], P = 0.001). Among the 5388 patients in whom data on in-hospital medication were available, in-hospital RASI therapy was associated with a significantly lower mortality (2.1% vs 16.7%, OR [95% CI]=0.11 [0.084 & ndash;0.14], p < 0.0001), confirmed after adjustment in both periods. Among the 62 SARSCoV-2 positive patients, RASI therapy, both at admission or in-hospital, showed no prognostic effect. Conclusions: This is the first study to investigate the impact of RASI therapy on the prognosis and SARSCoV2 infection of STEMI patients undergoing PPCI during the COVID-19 pandemic. Both pre-admission and in-hospital RASI were associated with lower mortality. Among SARSCoV2-positive patients, both chronic and in-hospital RASI therapy showed no impact on survival.Peer reviewe

Technological frames and the politics of automated electric light rail rapid transit in Poland and the United Kingdom

Light Rapid Transit (LRT) systems are often backed not only because they satisfy basic mobility functions, but because they can revitalize urban centers, affirm the legitimacy of state planners, support innovation and even cultivate an image of a city or region as progressive and modern. In this study, we argue that electrified, automated LRT systems can fulfill private functional frames, private symbolic frames, societal functional frames, and societal symbolic frames. In particular, we argue that light rail can fulfill private functional frames (making passengers feel safe, offering a cheap and efficient mode of transport), private symbolic frames (signifying political identity or exclusionary planning), societal functional frames (environmental stewardship), and societal symbolic frames (such as modernism or innovativeness). Essentially, these frames encompass not only what light rail is and does, but what it means and represents, and even some of its failures and challenges. The article then identifies ten specific frames associated with two case studies of automated light rail systems, the established Docklands Light Rail (DLR) in the United Kingdom, and the emerging Personal Rapid Transit (PRT) in Poland. We find that the DLR is not only a vital part of meeting (functional) demand for mobility, it is innovative and exciting to ride, legitimation of a conservative approach to project development, a social injustice (to some), an environmentally friendly alternative to cars, and a perceived magnet for global investment into the greater Docklands area. Similarly, the PRT is not only a reliable and safe mode of transit, but also a technical marvel, a monopoly breaking symbol, a clean and sustainable form of mobility, and a reflection of progressive Polish innovation and entrepreneurship (or enduring failure)
