Exploring Attitudes Toward "Sugar Relationships" Across 87 Countries: A Global Perspective on Exchanges of Resources for Sex and Companionship.

The current study investigates attitudes toward one form of sex for resources: the so-called sugar relationships, which often involve exchanges of resources for sex and/or companionship. The present study examined associations among attitudes toward sugar relationships and relevant variables (e.g., sex, sociosexuality, gender inequality, parasitic exposure) in 69,924 participants across 87 countries. Two self-report measures of Acceptance of Sugar Relationships (ASR) developed for younger companion providers (ASR-YWMS) and older resource providers (ASR-OMWS) were translated into 37 languages. We tested cross-sex and cross-linguistic construct equivalence, cross-cultural invariance in sex differences, and the importance of the hypothetical predictors of ASR. Both measures showed adequate psychometric properties in all languages (except the Persian version of ASR-YWMS). Results partially supported our hypotheses and were consistent with previous theoretical considerations and empirical evidence on human mating. For example, at the individual level, sociosexual orientation, traditional gender roles, and pathogen prevalence were significant predictors of both ASR-YWMS and ASR-OMWS. At the country level, gender inequality and parasite stress positively predicted the ASR-YWMS. However, being a woman negatively predicted the ASR-OMWS, but positively predicted the ASR-YWMS. At country-level, ingroup favoritism and parasite stress positively predicted the ASR-OMWS. Furthermore, significant cross-subregional differences were found in the openness to sugar relationships (both ASR-YWMS and ASR-OMWS scores) across subregions. Finally, significant differences were found between ASR-YWMS and ASR-OMWS when compared in each subregion. The ASR-YWMS was significantly higher than the ASR-OMWS in all subregions, except for Northern Africa and Western Asia.

Predictors of pretraumatic stress during the COVID-19 pandemic in Poland.

BACKGROUND: Pretraumatic stress has the same symptoms as post-traumatic stress but instead pertains to anticipated threats. There is evidence that pretraumatic stress occurs among soldiers and pregnant people. OBJECTIVE: We analyzed correlates of pretraumatic stress concerning the threat of COVID-19 infection. METHOD: Our pilot study was cross-sectional (N = 74); our main study was longitudinal and consisted of three waves (N = 1067, N = 894, and N = 752 for Waves 1, 2, and 3, respectively). Our pilot study used correlation and multiple linear regression. Our main study used quadratic regression and a random intercept cross-lagged panel model. RESULTS: The pilot study found that pretraumatic stress was positively correlated with agreeableness (r = .24, p < .01) and negatively correlated with emotional stability (r = -.30, p < .01) and intellect/imagination (r = -.37, p < .01). The main study demonstrated that pretraumatic stress was positively correlated with other measures of mental health problems during the COVID-19 pandemic and with perceived positive aspects of the pandemic (r = .11, p < .01). There is evidence of a U-shaped relationship between pretraumatic stress and perceived positive aspects of the pandemic. A random intercept cross-lagged panel model analysis demonstrated that pretraumatic stress in Wave 2 was negatively predicted by levels of prosocial behavior in Wave 1 (B = -1.130, p < .01). CONCLUSION: Mental health professionals should take into account pretraumatic stress, not only as a possible consequence of the COVID-19 pandemic outbreak but more generally as a risk in situations that are new, difficult, and challenging for people.

Perception of the Presumption of Innocence in the Context of Media Depictions of Violence: The Role of Participant's Gender, Type of Crime, and Defendant's Socioeconomic Status.

The #MeToo movement has provoked a worldwide discussion about sexual violence. Some critics of the movement argue that it violates the presumption of innocence. In the current study, we investigated the determinants of the perception of the presumption of innocence in the context of media depictions of violence. We took into account previous studies that suggest that people view more favorably defendants in rape trials than they do men accused of other crimes and that people view more favorably defendants with a high socioeconomic status than they do those with a low socioeconomic status. The current study investigated whether the perception of the presumption of innocence is related to the type of crime (sexual vs. nonsexual assault) or to the socioeconomic status of the defendant (a famous writer vs. a maintenance worker). We conducted a vignette-based study with a sample of Polish people (N = 158). The type of crime did not influence the perception of the presumption of innocence; however, women who participated in the study endorsed the presumption of innocence to a greater extent when the defendant had a high socioeconomic status. The theoretical and practical implications of these results are discussed.

Myths Concerning Sexual Violence Toward Women in Poland, Hungary, and Norway in the Context of System Justification Theory: The Role of Beliefs in the Biological Origins of Gender Differences and Ambivalent Sexism.

The purpose of this study was to compare attitudes toward rape in Poland, Hungary, and Norway. Based on system justification theory, we examined whether country of origin predicts levels of rape myth acceptance, beliefs in the biological origins of gender differences, and ambivalent sexism. There is also some evidence that beliefs in the biological origins of gender differences predict rape myth among Polish students and that this relationship is mediated by hostile sexism. The current study aimed to test whether this model can be applied to other countries. Participants (N = 266) were from Poland, Hungary, and Norway. The study was conducted online. The dependent and independent variables were measured with questionnaires. Polish participants had significantly higher levels of rape myth acceptance, beliefs in the biological origins of gender differences, and ambivalent sexism than Norwegian and Hungarian participants. Our proposed model was confirmed: belief in the biological origins of gender differences was associated with rape myth acceptance, with hostile sexism as a mediator. Benevolent sexism also turned out to be a mediator between beliefs in the biological origins of gender differences and rape myth acceptance. The mediational model of the relationship between beliefs in the biological origins of gender differences and rape myth acceptance can be applied to all three countries. This result suggests that anti-rape educational interventions should take into account the role of culture and society in the construction of gender differences.

Silver-Graphene Oxide Nanohybrids for Highly Sensitive, Stable SERS Platforms.

Graphene oxide-silver nanoparticle nanohybrids were synthesized by simple reduction of the silver nitrate and graphene oxide (GO) mixture in water using the mild reducing agent ascorbic acid. The concentration of ascorbic acid was varied to verify the possible influence of the GO surface composition on the efficiency of the hybrid material as substrates for surface enhanced Raman spectroscopy (SERS). Furthermore, the composites were conditioned in ammonia solution or in potassium hydroxide diluted solution. For comparison, the graphene oxide-silver nanoparticle composite has been synthesized using the ammonia-treated GO. All materials were characterized using spectroscopic and microscopic methods including UV-Vis, infrared, and Raman spectroscopy and scanning electron microscopy. The SERS efficiency of the nanohybrids was tested using 4-aminothiophenol (PATP). The optimal synthesis conditions were found. Ammonia and potassium peroxide drop-casted on the composite changed the SERS properties. The sample treated with KOH showed the best SERS enhancement. The variation of the SERS enhancement was correlated with the shape of the UV-Vis characteristics and the surface structure of the composites.

Who is the Most Stressed During the COVID-19 Pandemic? Data From 26 Countries and Areas.

BACKGROUND: To limit the rapid spread of COVID-19, countries have asked their citizens to stay at home. As a result, demographic and cultural factors related to home life have become especially relevant to predict population well-being during isolation. This pre-registered worldwide study analyses the relationship between the number of adults and children in a household, marital status, age, gender, education level, COVID-19 severity, individualism-collectivism, and perceived stress. METHODS: We used the COVIDiSTRESS Global Survey data of 53,524 online participants from 26 countries and areas. The data were collected between 30 March and 6 April 2020. RESULTS: Higher levels of stress were associated with younger age, being a woman, lower level of education, being single, staying with more children, and living in a country or area with a more severe COVID-19 situation. CONCLUSIONS: The COVID-19 pandemic revealed that certain people may be more susceptible to experience elevated levels of stress. Our findings highlight the need for public health to be attentive to both the physical and the psychological well-being of these groups.

Minimization of Male Suffering: Social Perception of Victims and Perpetrators of Opposite-Sex Sexual Coercion.

Studies show equal impact of sexual harassment (SH) on men and women, whereas lay perceptions are that women suffer more. We identify the phenomenon of minimization of male suffering (MMS), which occurs when people assume that SH has less effect on men's well-being and which results in the perpetrators of SH on men being evaluated less harshly. To verify whether these effects occur, we conducted two studies in which we presented stories describing acts of sexual coercion (SC, study 1) and SC or financial coercion (FC, study 2) and measured the perceived suffering of victims and the perception of the perpetrators. Both studies showed that female victims were perceived to suffer more from SC and FC and that perpetrators of both acts on women were evaluated more negatively. The results support our hypothesis that the suffering of male victims is minimized as they are perceived to suffer less than women.
