Success is all in the measures: androgenousness, curvaceousness, and starring frequencies in adult media actresses.

The debate of whether body-mass index (BMI) or waist-to-hip ratio (WHR) is the primary visual cue to female physical attractiveness (FPA) has generated considerable interest. However, experiments addressing this question typically have limited ecological validity and do not capture the ultimate goal of FPA, which is to elicit male sexual arousal. Hence, using an unobtrusive measures design, we retrieved movie and magazine starring frequencies of 125 adult media actresses from a company's database, operationalized starring frequencies as FPA measures, and tested their relationship to actresses' anthropometric data. Low BMI was related to frequent movie starring, while WHR, waist-to-bust ratio (WBR), and bust size were not. Conversely, low WHR, low WBR, and larger bust size were related to frequent magazine starring, while BMI was not. Visual cues to FPA might be domain-specific, with androgenousness cues salient for attractiveness evaluation of moving bodies and curvaceousness cues salient for posing bodies.

The shape of beauty: determinants of female physical attractiveness.

Rarely has one research area gained as much attention as that which is observed for female physical attractiveness. The past decade has resulted in numerous, exciting developments, particularly with respect to three proposed determinants of beauty: waist to hip ratio (WHR), body mass index (BMI), and curvaceousness. The goal of our paper is to provide a highly necessary review of contemporary research on the female attractiveness, including an in-depth examination of these factors. In our review, we first discuss WHR, an index of fat deposition, which is calculated by measuring the circumference of the waist compared to the circumference of the hips. WHR is controlled by the sex hormones, and increases as women age, and hence, may influence perceptions of attractiveness. This factor has been hotly contested, as some researchers have claimed that a WHR of approximately 0.7 is universally most attractive, whereas others have found inconsistent findings, or suggest the importance of other factors, such as BMI. Body mass index (BMI), calculated by dividing the body weight (in kilograms) by height (in meters) squared, serves as a measure of body fat. Although WHR and BMI are correlated, they lead to different conclusions, and the importance of BMI as a measure of female attractiveness is debated in the literature. Similar to WHR research, BMI and its role in attractiveness is not cross-culturally consistent and is affected by the availability of resources within a given environment. It may be the case that both WHR and BMI influence female attractiveness. However, there has been little investigation of this possibility. We have explored this issue in our research, which revealed that both influence attractiveness, but in addition, we noticed that curvaceousness was also a factor. Curvaceousness is the degree of "hourglass" shape as determined, for example, by the size of the bust, relative to the circumference of the hips and waist, and the size of the buttocks. However, curvaceousness does not appear to be temporally stable as a marker of attractiveness, and it is not consistent across modes of presentation. For example, models in male-oriented magazines are more curvaceous than models in female-oriented magazines. In summary, faced with these recent findings, it is difficult to ascertain agreement among the various factors, especially when researchers investigate each determinant in isolation. We conclude that, although researchers have made many important initial steps in examining female attractiveness, there remains much to be discovered.

Clark and Hatfield's evidence of women's low receptivity to male strangers' sexual offers revisited.

Although frequently cited, there has been no published scientific replication of Clark and Hatfield's (1989) and Clark's (1990) findings concerning women's low receptivity to male strangers' offers of casual sex. Consistently across three identically designed naturalistic experiments (aggregated N = 144), these authors reported a 0% acceptance rate by women. The present research analyzed an informal "real-life" journalistic project (N= 100) initiated by an Austrian magazine, in which results indicated a 6.1% acceptance rate (95% CI: 2.8-12.6%) for a complete stranger offering women immediate sexual involvement. Various contextual differences, such as setting, subjects' age and attractiveness, and age differences between requestor and receiver, probably contributed to the observed difference in outcome between the journalistic project and the original experiments. The present findings point to the importance of contextual effects in naturalistic investigations of women's receptivity to sexual offers.

Female intrasexual competition decreases female facial attractiveness.

Evolutionary theory predicts that female intrasexual competition will occur when males of high genetic quality are considered to be a resource. It is probable that women compete in terms of attractiveness since this is one of the primary criteria used by men when selecting mates. Furthermore, because hormones influence the mate-selection process, they may also mediate competition. One competitive strategy that women use is derogation--any act intended to decrease a rival's perceived value. To investigate intrasexual competition through derogation, the influence of oestrogen on women's ratings of female facial attractiveness was examined. During periods of high oestrogen, competition, and hence derogation, increased, as evidenced by lower ratings of female facial attractiveness. By contrast, oestrogen levels did not significantly affect ratings of male faces. These findings support the theory of female intrasexual competition with respect to attractiveness.

Patterns and universals of mate poaching across 53 nations: the effects of sex, culture, and personality on romantically attracting another person's partner.

As part of the International Sexuality Description Project, 16,954 participants from 53 nations were administered an anonymous survey about experiences with romantic attraction. Mate poaching--romantically attracting someone who is already in a relationship--was most common in Southern Europe, South America, Western Europe, and Eastern Europe and was relatively infrequent in Africa, South/Southeast Asia, and East Asia. Evolutionary and social-role hypotheses received empirical support. Men were more likely than women to report having made and succumbed to short-term poaching across all regions, but differences between men and women were often smaller in more gender-egalitarian regions. People who try to steal another's mate possess similar personality traits across all regions, as do those who frequently receive and succumb to the poaching attempts by others. The authors conclude that human mate-poaching experiences are universally linked to sex, culture, and the robust influence of personal dispositions.

Seasonality of suicide in Eastern Europe: a rejoinder to Lester and Moksony .

Seasonality of suicide in Hungary decreased from the 1980s to the 1990s, supporting the 2003 conclusion of Lester and Moksony. However, it was the strongest ever to be documented with contemporary suicide data, supporting the conjecture of Voracek, et al. (2002) that seasonality of suicide remains high in Eastern Europe. A new hypothesis regarding the co-occurrence of high incidence and strong seasonality of suicide is presented.

Universal sex differences in the desire for sexual variety: tests from 52 nations, 6 continents, and 13 islands.

Evolutionary psychologists have hypothesized that men and women possess both long-term and short-term mating strategies, with men's short-term strategy differentially rooted in the desire for sexual variety. In this article, findings from a cross-cultural survey of 16,288 people across 10 major world regions (including North America, South America, Western Europe, Eastern Europe, Southern Europe, Middle East, Africa, Oceania, South/Southeast Asia, and East Asia) demonstrate that sex differences in the desire for sexual variety are culturally universal throughout these world regions. Sex differences were evident regardless of whether mean, median, distributional, or categorical indexes of sexual differentiation were evaluated. Sex differences were evident regardless of the measures used to evaluate them. Among contemporary theories of human mating, pluralistic approaches that hypothesize sex differences in the evolved design of short-term mating provide the most compelling account of these robust empirical findings.

The Finno-Ugrian suicide hypothesis: variation in European suicide rates by latitude and longitude.

The marked variation regarding the suicide rate in 34 European countries is well described by regressing the national suicide rate on the capital cities' latitudes and on an interaction term of squared latitude multiplied with longitude. The interaction term explains 40.8% and 29.1% of men's and women's suicide rate, respectively, and latitude explains a further significant increment of 10.9% and 10.6% variance of men's and women's suicide rate, respectively. This regression model quantifies the Finno-Ugrian suicide hypothesis of Kondrichin and of Marusic and Farmer. The European countries highest in suicide rate constitute a contiguous, J-shaped belt, spanning from Finland to Austria. This area maps onto the second principal component identified for European gene distribution, representing ancestral adaptation to cold climates and the Uralic language dispersion. Thus, population differences in genetic risk factors may account for the spatial pattern in European suicide rates.

Evidence for lack of change in seasonality of suicide from Timiş County, Romania.

Evidence from politically and socially stable countries in Northern Europe and the Southern Hemisphere indicates a marked decrease in the seasonality of suicide over the past two decades. Generalizabiity of this trend to societies in transition has not yet been investigated. Data for suicide by hanging in Timiş County of Romania show both a nondecrease in seasonality of suicide for the current transitional period (1990-98), relative to the last decade of the Communist regime (1980-89) and shifts in location for suicide peak and trough months. Recent decreases in the seasonality of suicide might not generalize to societies in transition, and research would improve from focusing on the "natural laboratories" these societies represent.
