This study reports results from the first International Body Project (IBP-I), which surveyed 7,434 individuals in 10 major world regions about body weight ideals and body dissatisfaction. Participants completed the female Contour Drawing Figure Rating Scale (CDFRS) and self-reported their exposure to Western and local media. Results indicated there were significant cross-regional differences in the ideal female figure and body dissatisfaction, but effect sizes were small across high-socioeconomic-status (SES) sites. Within cultures, heavier bodies were preferred in low-SES sites compared to high-SES sites in Malaysia and South Africa (ds = 1.94-2.49) but not in Austria. Participant age, body mass index (BMI), and Western media exposure predicted body weight ideals. BMI and Western media exposure predicted body dissatisfaction among women. Our results show that body dissatisfaction and desire for thinness is commonplace in high-SES settings across world regions, highlighting the need for international attention to this problem.

For years, public discourse in science education, technology, and policy-making has focused on the "leaky pipeline" problem: the observation that fewer women than men enter science, technology, engineering, and mathematics fields and more women than men leave. Less attention has focused on experimentally testing solutions to this problem. We report an experiment investigating one solution: we created "microenvironments" (small groups) in engineering with varying proportions of women to identify which environment increases motivation and participation, and whether outcomes depend on students' academic stage. Female engineering students were randomly assigned to one of three engineering groups of varying sex composition: 75% women, 50% women, or 25% women. For first-years, group composition had a large effect: women in female-majority and sex-parity groups felt less anxious than women in female-minority groups. However, among advanced students, sex composition had no effect on anxiety. Importantly, group composition significantly affected verbal participation, regardless of women's academic seniority: women participated more in female-majority groups than sex-parity or female-minority groups. Additionally, when assigned to female-minority groups, women who harbored implicit masculine stereotypes about engineering reported less confidence and engineering career aspirations. However, in sex-parity and female-majority groups, confidence and career aspirations remained high regardless of implicit stereotypes. These data suggest that creating small groups with high proportions of women in otherwise male-dominated fields is one way to keep women engaged and aspiring toward engineering careers. Although sex parity works sometimes, it is insufficient to boost women's verbal participation in group work, which often affects learning and mastery.

Abstract In our work, the influences on subsequent firm risk taking of fixed incentives relative to variable incentives as well as the separate effects on subsequent corporate risk taking of variable incentives are examined. Focusing on the top management team members, we find a higher proportion of incentives that are devoted to fixed incentives relative to variable incentives tend to be inversely associated with subsequent firm risk taking. Managerial stock options are directly and uniformly associated with subsequent corporate risk taking. Executive shareholdings, however, display a curvilinear relationship with subsequent enterprise risk taking. Copyright © 2007 John Wiley & Sons, Ltd.

The literature on college women's experiences with sexual coercion is reviewed, with an emphasis on work published since 1990. Sexual coercion is defined as any situation in which one person uses verbal or physical means (including the administration of drugs or alcohol, with or without the other person's consent) to obtain sexual activity against consent. We argue that coercive sexual behavior among college students can best be understood within the context of other sexual behaviors and values on college campuses. Significant definitional and methodological problems are identified and discussed. Important victim, perpetrator, and situational variables are identified and discussed. These include attitudes toward women, beliefs about sexual behavior (including rape-supporting beliefs and values), communication problems, coercion-supporting peer groups (including fraternities and athletics), concepts of masculinity and femininity, sexual promiscuity, and alcohol.

The motives, family experiences, and personality characteristics of 341 college students with and without tattoos or piercings were studied. Participants completed Lippa's 1991 measures of the Big Five personality factors, a shortened version of the Body Cathexis Scale, a series of questions about their childhood experiences, and questions about risk-taking behaviors. In addition, reasons to have or not have body modifications and the perceptions of people with body modifications were investigated. Of the 116 men and 186 women, 25% and 33%, respectively, had at least one tattoo or body piercing. There were very few differences in the childhood experiences or personality characteristics of people with or without body modifications. Although people with body modifications did not differ from people without modifications on the Big Five personality measures, people without modifications perceived people with modifications as much different from themselves on these measures. These results indicate that tattoos and piercings in college students are associated with significantly more risk-taking behavior, greater use of alcohol and marijuana, and less social conformity. However, the traditional stereotype that body modifications are indicators of social or personal pathology does not describe contemporary college students.

Sexist attitudes and rape-supporting beliefs have long been linked to relationship aggression and sexual coercion. This study investigates how recent developments in the conceptualization and measurement of these variables are related to each other and how they are related to aggressive and coercive behaviors. Second-generation measures of sexism and rape-supporting beliefs were found to be related to each other and to aggressive and sexually coercive behaviors. Relationships between attitude measures appeared to be based primarily on shared belief systems, whereas relationships between attitude measures and aggressive behavior appeared to be based primarily on generalized hostility toward women.

Aggressive male sports have been criticized as bastions of sexism and training grounds for aggression against women, but there have been few empirical demonstrations of these alleged relationships. The authors studied self-reported dating aggression and sexual coercion in 147 college men. Men who had participated in aggressive high school sports, as compared with other men, engaged in more psychological aggression, physical aggression, and sexual coercion toward their dating partners, caused their partners more physical injury, were more accepting of violence, had more sexist attitudes and hostility toward women, were more accepting of rape myths, and were less tolerant of homosexuality. Results indicate that participation in aggressive high school sports is one of the multiple developmental pathways leading to relationship violence.

Ability of the Test of Variables of Attention (TOVA) to distinguish between referred children with attention-deficit/hyperactivity disorder (ADHD) and other (OTHER) clinical diagnoses were studied. The ADHD group differed from the OTHER group on TOVA variables and most measures from the Revised Conners Teacher Rating Scale (RCTRS) and ADD-H Comprehensive Teacher's Rating Scale (ACTeRS). The criteria of any one TOVA variable > 1.5 standard deviations from age and sex adjusted means correctly identified 80% of the sample with attention deficit disorders and 72% of the sample without attention deficit disorder. Cases misclassified by teacher ratings were often correctly classified by the TOVA and conversely. The TOVA makes a unique and important contribution to diagnostic evaluations.

Direct and indirect aggression were studied in college students from China (women n=122; men n=97), a highly collectivistic culture; the US (women n=137; men n=136), a highly individualistic culture; and Poland (women n=105; men n=119), a culture with intermediate levels of collectivism and individualism. Consistent with a hypothesis derived from national differences in relative levels of collectivism and individualism, both direct and indirect aggression were higher in the US than in Poland and higher in Poland than in China. The theoretical implication of these results and directions for future research were discussed.

Body dissatisfaction and disordered eating were compared across groups of college women from China ( n = 109), South Korea ( n = 137), and the United States ( n = 102). Based on cultural differences in the amount of exposure to Western appearance standards, particularly the thin-body ideal, sociocultural theory ( Thompson, Heinberg, Altabe, & Tantleff-Dunn, 1999 ) would predict that body dissatisfaction and disordered eating would be highest in the U.S. sample and lowest in the Chinese sample. In contrast, based on the speed and pervasiveness of changes in women's roles, feminist theory ( Bordo, 1993 ; Jeffreys, 2005 ) would predict that body dissatisfaction and disordered eating would be highest in the Korean sample and lowest in the U.S. sample. Multidimensional measures indicated the highest levels of body dissatisfaction and disordered eating in the Korean sample and the lowest levels in the U.S. sample, indicating that predictions derived from feminist theory were a better fit to the data than predictions derived from sociocultural theory. Results indicated that theoretical understandings of body dissatisfaction must recognize not only differences between Western and non-Western cultures, but also differences among non-Western cultures.

Among the most popular reasons that people feed wild birds is that they want to help birds. The extent to which supplemental food helps birds, however, is not well established. From spring 2011 to spring 2014, we examined how feeding of wild birds influences the health of individual birds at forested sites in central Illinois, USA. Specifically, we compared three forested sites where we provided supplemental food with three forested sites for which no supplemental food was available and monitored changes in the individual health of birds. In addition, we determined whether any changes in bird health had occurred after feeders had been removed from sites 10 months before. Generally, the individual health of birds improved with supplemental feeding, including increased antioxidant levels, reduced stress (heterophil-to-lymphocyte ratio) and more rapid feather growth. In some species, we also found improved body condition index scores and innate immune defense. The difference among sites was not present 10 months after feeders were removed, suggesting that the impact on health was indeed related to supplemental feeding. Potential negative effects of supplemental feeding were also found, including an increase in infectious disease prevalence among individual birds at forested sites where supplemental food was offered. Birds with clear signs of pathology showed deficits in most of the physiological metrics in which birds at feeder sites typically showed improved health condition. At the peak of prevalence of infectious disease, 8.3% of all birds at feeders exhibited symptoms of conjunctivitis, pox, dermal disease or cloacal disease. We found both positive and negative impacts of wild bird feeding, and that, in general, birds that had access to supplemental food were in better physiological condition. Moreover, the negative effects we found may be mitigated by hobbyists engaging in safer bird-feeding practices.

We use the construct of the “other” to explore how hate operates rhetorically within the virtual conclave of Stormfront, credited as the first hate Web site. Through the Internet, white supremacists create a rhetorical vision that resonates with those who feel marginalized by contemporary political, social, and economic forces. However, as compared to previous studies of on-line white supremacist rhetoric, we show that Stormfront discourse appears less virulent and more palatable to the naive reader. We suggest that Stormfront provides a “cyber transition” between traditional hate speech and “reasonable racism,” a tempered discourse that emphasizes pseudo-rational discussions of race, and subsequently may cast a wider net in attracting audiences.

The contributions of aggression in family of origin, acceptance of rape myths, sexist attitudes, the Big-Five personality factors, and self-esteem to the experience of sexual coercion or aggression were studied in a homogenous sample of young college students. Significant relationships were found between aggression in the family of origin and experience with sexual coercion for both males and females. Stepwise multiple regression indicated that personality and attitude measures, including acceptance of rape myths, were not related to sexual aggression in males. A similar analysis for females found small relationships between extroversion and childhood selfesteem and experience with sexual aggression. The implications of these results are discussed.

The electronic and optical properties of the cubic perovskite, BaSnO3, are compared with the well-known transparent conducting oxides (TCOs), SnO2 and In2O3. The optical band gaps of the undoped compounds, as measured by diffuse reflectance spectroscopy on powdered samples, are 3.1 eV for BaSnO3 and 3.8 eV for SnO2. Electronic structure calculations show that both compounds possess a large conduction band dispersion, which suggests that BaSnO3, like SnO2, should be a good TCO if it can be n-doped. To explore this possibility the properties of substitutionally doped, BaSn1–xSbxO3 samples were investigated. The electrical conductivity increases drastically for BaSn1–xSbxO3 samples with x ≤ 0.05, showing a transition from an insulating to a metallic state. For higher doping levels, 0.05 < x < 0.15, the conductivity saturates at 4 S cm–1. This is accompanied by saturation in the expansion of the cubic lattice parameter. The color of the pellets changed from white (x = 0) to bluish black (x = 0.15). This darkening originates from the formation of an intense and broad optical absorption band centered at 1200–1300 nm for the more highly doped samples. This absorption band spans both the visible and the near-infrared regions, resulting in a loss of transparency. Various spectroscopic techniques were used to elucidate the observed behavior. Mössbauer spectroscopy reveals the presence of mixed valent antimony, Sb3+(5s2)/Sb5+(5s0), as x increases. ESR spectra collected on a BaSn0.99Sb0.01O3 sample indicate that only ∼5% of unpaired electrons are present as delocalized carriers. The other 95% are localized to form a Sn3+ trapped electron center. To explain the tendency for carrier localization in doped BaSnO3 a mechanism based on strong electron–phonon interactions in perovskites containing cations with (n – 1)d10ns0 electronic configuration is proposed. This mechanism explains why BaSn1–xSbxO3 possesses relatively poor TCO characteristics, in sharp contrast to widely used TCO materials Sn1–xSbxO2 and In1–xSnxO1.5.

Sterile neutrinos are attractive dark matter candidates. Their parameter space of mass and mixing angle has not yet been fully tested despite intensive efforts that exploit their gravitational clustering properties and radiative decays. We use the limits on gamma-ray line emission from the Galactic center region obtained with the SPI spectrometer on the INTEGRAL satellite to set new constraints, which improve on the earlier bounds on mixing by more than 2 orders of magnitude, and thus strongly restrict a wide and interesting range of models.

We use the Chandra unresolved X-ray emission spectrum from a 12'-28' (2.8-6.4 kpc) annular region of the Andromeda galaxy to constrain the radiative decay of sterile neutrino warm dark matter. By excising the most baryon-dominated, central 2.8 kpc of the galaxy, we reduce the uncertainties in our estimate of the dark matter mass within the field of view and improve the signal-to-noise ratio of prospective sterile neutrino decay signatures relative to hot gas and unresolved stellar emission. Our findings impose the most stringent limit on the sterile neutrino mass to date in the context of the Dodelson-Widrow model, m_s < 2.2 keV (95% C.L.). Our results also constrain alternative sterile neutrino production scenarios at very small active-sterile neutrino mixing angles.

Plants are rooted and immobile and must accept whatever fate brings their way. They are not, however, static. Flowers open and close. Leaves extend to the daylight and fold up by night or, in shade-loving species, turn away from direct sunlight or, in Mimosa pudica, collapse suddenly and dramatically when touched. Modified leaves of the Venus' flytrap snap shut on doomed insect prey.

The growth trajectory of ethnically and linguistically diverse individuals in the United States, particularly for youth, compels the education system to have urgent awareness of how diverse aspects of culture (e.g., Spanish-speaking, Black Latina student) are implicated in outcomes in American school systems. Students spend a significant amount of time in the school ecology, and this experience plays an important role in their well-being. Diverse ethnic, racial, and linguistic students face significant challenges and are placed at considerable risk by long-observed structural inequities evidenced in society and schools. Teachers must develop the capacity to be culturally sensitive, provide culturally responsive pedagogy, and regularly self-assess for biases implicated in positive academic outcomes for students in kindergarten through Grade 12. Research and practice have suggested that racism and discrimination in the form of racial microaggressions are observed daily in schools and classrooms. This article provides an overview of racial microaggressions in the school context and their damaging effects on students. We provide specific examples of microaggressions that may be observed in the U.S. classroom environment and how schools can serve as a positive intervention point to ameliorate racism, discrimination, and racial and language microaggressions. This comprehensive approach blends theory with practice to support the continued development of cultural humility, culturally sustaining pedagogy, and an equity-responsive climate.
