The pupil dilates to images that are arousing. In Experiment 1, we examined if the pupil’s response to brief presentations (2,000 ms) of static images could be used to identify individuals’ sexual orientation. Participants were grouped according to their self-reported gender and sexual orientation (male heterosexual, N = 20; male bisexual, N = 13; male homosexual, N = 19; female heterosexual, N = 28; female bisexual, N = 21; female homosexual, N = 17). Pupil size was monitored to images of men in seminude poses, women in seminude poses, or neutral images. Every group showed the same pattern of responses, with the greatest dilation to male images, then female images, and least dilation to the neutral images. Experiment 2 used more tightly controlled stimuli and tested at two different image durations (150 and 3,000 ms). Both heterosexual men (N = 18) and women (N = 20) showed greater pupil dilation to images of nude men than to nude women. However, in Experiment 3, where we reduced the erotic content by using images of clothed models, both heterosexual men and women showed greater pupil dilation to images of women. The results showed that while the pupil does dilate strongly to sexual imagery, its response to these brief static images does not correspond to a person’s sexual orientation in a simple manner.  相似文献

This study evaluates a model linking shyness, aspects of peer relations, and internalizing problems among young adolescents in the People's Republic of China. Participants were 547 young adolescents from Shanghai, China (46% boys; Mage = 10.35 years, SD = 0.77 years) who completed peer nominations of shyness, rejection, and victimization, and self‐report measures of loneliness, depression, and friendship support. Analyses demonstrated that peer difficulties (rejection, victimization) mediated the associations between shyness and internalizing problems. However, moderated mediation analyses revealed a protective effect for highly supportive friendships, especially for boys. Findings highlight the importance of considering different types of peer experiences in studies of shy young adolescents and are discussed in terms of importance to theory and intervention in China and elsewhere.  相似文献

Custodial grandparenting can be especially challenging for older grandmothers facing age specific issues. Kinship navigator programs are social service delivery programs intended to inform grandparents and other relatives raising children about available resources and services, provide information specific to their individual needs, and help families navigate service systems. Our study utilizes self-report data from one kinship navigator federal demonstration project, which used a randomized control trial, to examine demographic characteristics for grandmothers under and over 55 years of age, whether grandmother caregivers (≥55 years) improve family resilience, social support, and caregiver self-efficacy, and which interventions improved outcomes for grandmothers (≥55 years). Each participant was randomly assigned to one of four groups: Usual Care (traditional child welfare services), Standard Care (family support and case management), Peer-to-Peer Care Only, and Full Kin Tech Care (peer navigators with computer access and interdisciplinary team). Thirty-nine percent of grandmothers (55-75 years) were mostly living in poverty, predominantly Caucasian, with 36% identifying as African American/Black, with at least one to two children at home. Repeated-measures ANOVAs for each subscale showed statistically significant within- and between-group differences for Family Functioning, Social Supports, Concrete Supports, Child Development, and Nurturing and Attachment, with the exception of Usual Care, which showed a decline in protective factors consistently across subscales. Future research with kinship families could qualitatively examine the experiences for older women in navigator programs and replication of kinship navigator programs could build capacity in data collection and maintenance systems to gain better perspective about how systems of care impact families.  相似文献

While children are one of the groups at risk in disasters, they can also take an active part in disaster management, provided that the opportunity is given. This research examined the effect of disaster experience, disaster education, country, and city socioeconomic status on children's perceived risk and preparedness with a survey of 1335 children between 11 and 14 years old, in Nepal and Turkey. The survey used questionnaires and the pictorial representation of illness and self measure (PRISM) tool. Results showed that (1) children's risk perceptions were in line with their country-specific objective risks; (2) there were differences between the countries in relation to perception of risk for all the hazards except wildfire; (3) socioeconomic status had a statistically significant effect on children's perceptions of risk and preparedness for earthquakes, wildfires, that is, children who live in wealthier places had higher perceived risk and preparedness; (4) children in both countries showed similar trends in their knowledge of the correct protective actions to take in the event of a hazard occurrence. However, there is still room to enhance children's knowledge, in terms of safety behaviors, as the children selected many incorrect protective actions. There are important implications in terms of child-centered disaster management which hopefully will make life safer and help to create more resilience to disaster in society as a whole.  相似文献

In the 1990s, many immigrants bypassed established gateways like Los Angeles, New York, Chicago, and Miami to create new immigrant destinations across the US. In this paper, we examine how segregation and spatial assimilation might differ between established gateways and new destinations among the 150 largest metropolitan areas. Using data from the 1990 and 2000 censuses, we calculate levels of dissimilarity for Hispanics and Asians by nativity for these two gateway types. Our findings show that segregation levels are consistently lower in new destinations. However, Hispanics in new destinations experienced significant increases segregation during the 1990s, suggesting a convergence in residential patterns by destination type. Nevertheless, in both destinations the native-born are less segregated than the foreign born—consistent with immigrant spatial incorporation. Finally, socioeconomic indicators are generally consistent with predictions of spatial assimilation.  相似文献

Immigration is an important population dynamic at work in the U.S., but we know little about its impact on American obesity. Built on nutrition transition and immigration theories, this paper provides explanations for immigrants’ initial body composition advantage, its partial erosion over time, and the gender difference in the erosion. We find evidence that the American obesity epidemic would be much more severe without the mass immigration that began in 1965. In addition to confirming the erosion in immigrants’ body composition advantage, we further find that this erosion is weaker for men than for women. Once immigration’s impact is teased out, racial/ethnic disparities in body composition greatly differ from what we observe. This study provides gender‐specific estimates for the differences in obesity by nativity and residence duration and the net level of Hispanic‐white and Asian‐white disparities at the mean body mass index (BMI) as well as the overweight, Stage‐1, and Stage‐2 obesity cutoffs. Our findings suggest that immigration must be taken into account when addressing public health concerns.  相似文献

This article identifies the factors associated with variation in the complexity of formal equal employment opportunity (EEO) structures across a sample of Washington and Oregon hospitals. Understanding such variation provides insight into two key organizational processes: commitment to workplace equality and response to external pressures for equality. We draw on Oliver’s (1991) organizational strategic response theory to document the extent to which a hospital’s patient demographics, legal regulation, economic sector, geographic location, and health system membership are related to complexity in the level of a hospital’s formal EEO structures. Findings from ordered logistic regression analyses demonstrate that the presence of a nurse union and federal regulation of a hospital by the Equal Employment Opportunity Commission (EEOC) are associated with less complex EEO structures. Meanwhile, urbanization is associated with more complex EEO structures. We discuss implications of these results for research and policy and offer the beginnings of a general theory of organizational variation.  相似文献

Two white researchers critique the professional veil of silence they created as they reflected on a qualitative study they performed 12 years earlier. Autoethnography and performance ethnography are utilized to examine the ways in which whiteness can remain unexamined throughout the research process due to the construction of white positional identities within the figured world of research. White privilege and white talk, specifically white silence and hyperpoliteness as they relate to white researchers conducting research, are used critique the research purpose and process. The researchers conclude that white researchers should attend to questions of privilege and white racial identity as they plan, conduct, and disseminate their research.  相似文献

Sex Differences in Self-awareness of Smiling During a Mock Job Interview   总被引:1,自引:0,他引:1  
The present study examined sex differences in awareness of smiling behavior during a job interview, along with intended outcomes of false smiling. Male and female participants were assigned to the interviewee role of a mock job interview and were videotaped. Results indicate that women were more self-aware of false, but not genuine, smiling. In addition, women reported using false smiles to mask negative emotion and to appear enthusiastic more than did men. Naïve judges rated women who smiled in an attempt to mask negative emotion more harshly than men who smiled for this reason. Implications of these findings for the understanding of sex differences in smiling are discussed.  相似文献
