In certain segments of the space community, the idea of colonizing other planetary bodies has been popular for decades. Disproportionate attention to this idea in the mass media, and lip service from key U.S. government officials, may convey the impression that the goal of space colonization1 and exploitation is universally embraced. This author will argue that this is not the case, and, further, should not be. Given the current state of humankind’s overall ethical and moral development, humans should clean up the mess they have made on their home planet and learn how to take care of one another here before they go off into space. 相似文献

The effects of participants’ gender and propensity to sexually harass were examined in a sexual harassment case in which the gender of the harassers and victim were manipulated systematically. Male and female participants scoring either high or low on the Likelihood to Sexually Harass (LSH) scale (Pryor, 1987) reviewed an ostensibly real hostile work environment case and made judgments about the case. When participants were the same gender as the victim, individual differences in LSH failed to influence their judgments. When the participants’ gender was the opposite of the victim's, those low in LSH perceived the behaviors as more likely to be sexual harassment than those high in LSH. These results are discussed and their implications considered. 相似文献

The Schwartz Value Survey (SVS) was administered to 979 Canadian knowledge workers to determine whether differences in value priorities between men and women differed significantly between members of the Baby Boomer generation and members of Generation X. Multivariate analysis of covariance controlling for education, income, and scale use revealed a significant gender-by-generation interaction, which signifies that the patterns of differences between men's and women's value priorities were different for Baby Boomers and Generation Xers. Four of the 10 SVS value types (i.e., power, tradition, universalism, and achievement) were associated with both gender and generation. A number of other value types were associated solely with generation. The findings suggest that both gender and generation are important variables in the study of values and should not be considered in isolation of each other. 相似文献

The purpose of this study was to gain insight into the perspective of individuals with congenital disabilities about spirituality as a coping mechanism during crucial times in their lives. Qualitative analysis of interviews assessing turning points in the lives of 15 adults (6 women and 9 men; M = 37 years) with spina bifida, cerebral palsy, or attention deficit disorder was performed to determine how spirituality assisted them at these crucial times. Four recurring themes were identified: God as a guiding force, inner strength, meaning in life, and appropriateness of the use of spirituality in counseling. The authors discuss their findings and the use of spirituality in counseling adults with congenital disabilities. 相似文献

Using a sample of 248 ninth and tenth grade students at public high schools, we examined adolescents’ perceptions of family
connectedness, intrinsic religiosity, and adolescents’ gender in relation to depressed mood and whether intrinsic religiosity
and gender moderated the association of aspects of family connectedness to adolescent depressed mood. Using hierarchical multiple
regression analyses we tested models separately for three forms of family connectedness (overall family cohesion, mothers’
support, and fathers’ support), intrinsic religiosity, and depressed mood. In each model, family connectedness was negatively
associated with depressed mood. Intrinsic religiosity was not significantly associated with depressed mood. However, in the
mothers’ support model, both a two-way interaction (mothers’ support × intrinsic religiosity) and a three-way interaction
(adolescents’ gender × mothers’ support × intrinsic religiosity) were significantly related to depressed mood. In the two-way
interaction, higher intrinsic religiosity was a moderator, strengthening the association between mothers’ support and depressed
mood. In the three-way interaction, gender differences were found. For boys, high intrinsic religiosity strengthened the association
between mothers’ support and depressed mood. Among girls, when mothers’ support was low, intrinsic religiosity provided an
additional source of connectedness in protecting against depressed mood. Our findings show that connectedness in overall family
systems, mother–adolescent subsystems, and father–adolescent subsystems are all important to emotional resilience in adolescents
by protecting against depressed mood. Future studies of adolescent religiosity may benefit from including diverse forms of
family connectedness in understanding the protective processes provided by aspects of religiosity in promoting adolescents’
emotional resilience. 相似文献

An item factor analysis and item response theory-based revision of the Everyday Discrimination Scale
Stucky BD Gottfredson NC Panter AT Daye CE Allen WR Wightman LF 《Cultural diversity & ethnic minority psychology》2011,17(2):175-185
The Everyday Discrimination Scale (EDS), a widely used measure of daily perceived discrimination, is purported to be unidimensional, to function well among African Americans, and to have adequate construct validity. Two separate studies and data sources were used to examine and cross-validate the psychometric properties of the EDS. In Study 1, an exploratory factor analysis was conducted on a sample of African American law students (N = 589), providing strong evidence of local dependence, or nuisance multidimensionality within the EDS. In Study 2, a separate nationally representative community sample (N = 3,527) was used to model the identified local dependence in an item factor analysis (i.e., bifactor model). Next, item response theory (IRT) calibrations were conducted to obtain item parameters. A five-item, revised-EDS was then tested for gender differential item functioning (in an IRT framework). Based on these analyses, a summed score to IRT-scaled score translation table is provided for the revised-EDS. Our results indicate that the revised-EDS is unidimensional, with minimal differential item functioning, and retains predictive validity consistent with the original scale. 相似文献

Human toddlers learn about objects through second-by-second, minute-by-minute sensory-motor interactions. In an effort to understand how toddlers' bodily actions structure the visual learning environment, mini-video cameras were placed low on the foreheads of toddlers, and for comparison also on the foreheads of their parents, as they jointly played with toys. Analyses of the head camera views indicate visual experiences with profoundly different dynamic structures. The toddler view often consists of a single dominating object that is close to the sensors and thus that blocks the view of other objects such that individual objects go in and out of view. The adult view, in contrast, is broad and stable, with all potential targets continually in view. These differences may arise for several developmentally relevant reasons, including the small visuo-motor workspace of the toddler (short arms) and the engagement of the whole body when actively handling objects. 相似文献

This paper presents a geometrical analysis of how local interactions in a large population of categories packed into a feature space create a global structure of feature relevance. The theory is a formal proof that the joint optimization of discrimination and inclusion creates a smooth space of categories such that near categories in the similarity space have similar generalization gradients. Packing theory offers a unified account of several phenomena in human categorization including the differential importance of different features for different kinds of categories, the dissociation between judgments of similarity and judgments of category membership, and children's ability to generalize a category from very few examples. 相似文献
