    Two studies tested whether people feel threatened by another individual verbally complimenting their romantic partner. Such compliments may indicate that the other person is a potential rival who will try to poach their mate. Across two studies, women were more threatened than men when imagining another person complimenting their partner\u27s physical appearance. There were no sex differences in response to imagining another person complimenting their partner\u27s sense of humor. When another person compliments one\u27s partner\u27s physical appearance, this indicates that they may be sexually attracted to the partner. Mediation analyses revealed that the sex difference occurs because women believe men are more open to casual sex, and therefore more vulnerable to mate poaching when another person expresses sexual interest in them

    The longitudinal development and other characteristics of the EECR induced atmospheric showers can be studied from space by detecting the fluorescence light induced in the atmospheric nitrogen. According to the Airwatch concept a single fast detector can be used for measuring both intensity and time development of the streak of fluorescence light produced by the atmospheric shower induced by an EECR. In the present communication the detection capabilities for the EECR observation from space are discussed.Comment: 3 pages (LaTeX). To appear in the Proceedings of TAUP'9

    Background: The Global Burden of Diseases, Injuries, and Risk Factors Study 2015 provides an up-to-date synthesis of the evidence for risk factor exposure and the attributable burden of disease. By providing national and subnational assessments spanning the past 25 years, this study can inform debates on the importance of addressing risks in context. Methods: We used the comparative risk assessment framework developed for previous iterations of the Global Burden of Disease Study to estimate attributable deaths, disability-adjusted life-years (DALYs), and trends in exposure by age group, sex, year, and geography for 79 behavioural, environmental and occupational, and metabolic risks or clusters of risks from 1990 to 2015. This study included 388 risk-outcome pairs that met World Cancer Research Fund-defined criteria for convincing or probable evidence. We extracted relative risk and exposure estimates from randomised controlled trials, cohorts, pooled cohorts, household surveys, census data, satellite data, and other sources. We used statistical models to pool data, adjust for bias, and incorporate covariates. We developed a metric that allows comparisons of exposure across risk factors—the summary exposure value. Using the counterfactual scenario of theoretical minimum risk level, we estimated the portion of deaths and DALYs that could be attributed to a given risk. We decomposed trends in attributable burden into contributions from population growth, population age structure, risk exposure, and risk-deleted cause-specific DALY rates. We characterised risk exposure in relation to a Socio-demographic Index (SDI). Findings: Between 1990 and 2015, global exposure to unsafe sanitation, household air pollution, childhood underweight, childhood stunting, and smoking each decreased by more than 25%. Global exposure for several occupational risks, high body-mass index (BMI), and drug use increased by more than 25% over the same period. All risks jointly evaluated in 2015 accounted for 57·8% (95% CI 56·6–58·8) of global deaths and 41·2% (39·8–42·8) of DALYs. In 2015, the ten largest contributors to global DALYs among Level 3 risks were high systolic blood pressure (211·8 million [192·7 million to 231·1 million] global DALYs), smoking (148·6 million [134·2 million to 163·1 million]), high fasting plasma glucose (143·1 million [125·1 million to 163·5 million]), high BMI (120·1 million [83·8 million to 158·4 million]), childhood undernutrition (113·3 million [103·9 million to 123·4 million]), ambient particulate matter (103·1 million [90·8 million to 115·1 million]), high total cholesterol (88·7 million [74·6 million to 105·7 million]), household air pollution (85·6 million [66·7 million to 106·1 million]), alcohol use (85·0 million [77·2 million to 93·0 million]), and diets high in sodium (83·0 million [49·3 million to 127·5 million]). From 1990 to 2015, attributable DALYs declined for micronutrient deficiencies, childhood undernutrition, unsafe sanitation and water, and household air pollution; reductions in risk-deleted DALY rates rather than reductions in exposure drove these declines. Rising exposure contributed to notable increases in attributable DALYs from high BMI, high fasting plasma glucose, occupational carcinogens, and drug use. Environmental risks and childhood undernutrition declined steadily with SDI; low physical activity, high BMI, and high fasting plasma glucose increased with SDI. In 119 countries, metabolic risks, such as high BMI and fasting plasma glucose, contributed the most attributable DALYs in 2015. Regionally, smoking still ranked among the leading five risk factors for attributable DALYs in 109 countries; childhood underweight and unsafe sex remained primary drivers of early death and disability in much of sub-Saharan Africa. Interpretation: Declines in some key environmental risks have contributed to declines in critical infectious diseases. Some risks appear to be invariant to SDI. Increasing risks, including high BMI, high fasting plasma glucose, drug use, and some occupational exposures, contribute to rising burden from some conditions, but also provide opportunities for intervention. Some highly preventable risks, such as smoking, remain major causes of attributable DALYs, even as exposure is declining. Public policy makers need to pay attention to the risks that are increasingly major contributors to global burden. Funding: Bill & Melinda Gates Foundation

    A MODEST review

    We present an account of the state of the art in the fields explored by the research community invested in 'Modeling and Observing DEnse STellar systems'. For this purpose, we take as a basis the activities of the MODEST-17 conference, which was held at Charles University, Prague, in September 2017. Reviewed topics include recent advances in fundamental stellar dynamics, numerical methods for the solution of the gravitational N-body problem, formation and evolution of young and old star clusters and galactic nuclei, their elusive stellar populations, planetary systems, and exotic compact objects, with timely attention to black holes of different classes of mass and their role as sources of gravitational waves. Such a breadth of topics reflects the growing role played by collisional stellar dynamics in numerous areas of modern astrophysics. Indeed, in the next decade, many revolutionary instruments will enable the derivation of positions and velocities of individual stars in the Milky Way and its satellites and will detect signals from a range of astrophysical sources in different portions of the electromagnetic and gravitational spectrum, with an unprecedented sensitivity. On the one hand, this wealth of data will allow us to address a number of long-standing open questions in star cluster studies; on the other hand, many unexpected properties of these systems will come to light, stimulating further progress of our understanding of their formation and evolution.Comment: 42 pages; accepted for publication in 'Computational Astrophysics and Cosmology'. We are much grateful to the organisers of the MODEST-17 conference (Charles University, Prague, September 2017). We acknowledge the input provided by all MODEST-17 participants, and, more generally, by the members of the MODEST communit

    The Adaptive Utility of Deontology: Deontological Moral Decision-Making Fosters Perceptions of Trust and Likeability

    No full text
    Although various motives underlie moral decision-making, recent research suggests that deontological moral decision-making may have evolved, in part, to communicate trustworthiness to conspecifics, thereby facilitating cooperative relations. Specifically, social actors whose decisions are guided by deontological (relative to utilitarian) moral reasoning are judged as more trustworthy, are preferred more as social partners, and are trusted more in economic games. The current study extends this research by using an alternative manipulation of moral decision-making as well as the inclusion of target facial identities to explore the potential role of participant and target sex in reactions to moral decisions. Participants viewed a series of male and female targets, half of whom were manipulated to either have responded to five moral dilemmas consistent with an underlying deontological motive or utilitarian motive; participants indicated their liking and trust toward each target. Consistent with previous research, participants liked and trusted targets whose decisions were consistent with deontological motives more than targets whose decisions were more consistent with utilitarian motives; this effect was stronger for perceptions of trust. Additionally, women reported greater dislike for targets whose decisions were consistent with utilitarianism than men. Results suggest that deontological moral reasoning evolved, in part, to facilitate positive relations among conspecifics and aid group living and that women may be particularly sensitive to the implications of the various motives underlying moral decision-making

    The Influence of Disclosure and Ethics Education On Perceptions of Financial Conflicts of Interest

    No full text
    This study explored how disclosure of financial conflicts of interest (FCOI) influences naïve or “lay” individuals’ perceptions of the ethicality of researcher conduct. On a between-subjects basis, participants read ten scenarios in which researchers disclosed or failed to disclose relevant financial conflicts of interest. Participants evaluated the extent to which each vignette represented a FCOI, its possible influence on researcher objectivity, and the ethics of the financial relationship. Participants were then asked if they had completed a college-level ethics course. Results indicated that FCOI disclosure significantly influenced participants’ perceptions of the ethicality of the situation, but only marginally affected perceptions of researcher objectivity and had no significant influence on perceptions of the existence of FCOIs. Participants who had previously completed a college-level ethics course appeared more sensitive to the importance of FCOI disclosure than those who lacked such background. This result suggests that formal ethical training may help individuals become more critical consumers of scientific research

    Women’s dangerous world beliefs predict more accurate discrimination of affiliative facial cues.

    © 2017 American Psychological Association. Cues indicating environmental threat have been shown to influence women\u27s preferences for physical traits in men. For example, women\u27s beliefs about their vulnerability to aggression are associated with a stronger preference for physical formidability and aggressive dominance in male bodies and faces. In the current study, we extend these previous findings by testing whether dangerous world beliefs predict accuracy in processing facial cues associated with affiliation or deception. In addition, we include a sample of men to determine if these effects generalize to both genders. In the present study, participants viewed a series of images of a target displaying both Duchenne (genuine) and non-Duchenne (posed) smiles and were asked to categorize them as real or fake; participants also completed the Belief in a Dangerous World scale. Results revealed that for women, greater dangerous world beliefs predicted greater accuracy in discriminating real and fake smiles; no relationship was observed between dangerous world beliefs and smile detection accuracy for men. These findings uniquely demonstrate that dangerous world beliefs predict greater accuracy in adaptive face perception; however, this relationship seems to be specific to women
