This paper had two objectives. First, we developed for each large metropolitan area of the United States with a population of 500,000 or more in 1990 four indexes of gay partnering and four indexes of lesbian partnering. We compared and related these indexes and their variable measurements with one another. Second, using what we argue is the statistically and demographically preferred set of gay and lesbian partnering rates, we proposed and tested an assortment of ecological hypotheses relating characteristics of the metropolitan areas with the gay and lesbian partnering rates. Rates of gay and lesbian partnering, we show, are more influenced by such metropolitan characteristics as physical climate and the crime rate than by a religious characteristic such as the number of Southern Baptist adherents. Among the conclusions of the paper is our claim that there needs to be greater consideration of the methodological issues related to the use of government data for the development of rates of gay and lesbian partnering.  相似文献

Although scholars have studied outside executive succession for decades, there is still no clear definition of the term outsider. We focus on a new dimension of outsiderness, the industrial background of executives hired from outside the firm into a CEO position. This paper examines the antecedents of boards' decisions on the industry origin of outside successors as well as the short-term stock market response. We find that firms with more independent boards and with blockholders owning large amounts of stock are more likely to hire industry unrelated successors. However, the board's decision does not strictly follow the rhetoric of stockholder's interests. The stock market reacts more positively to outside CEO succession announcements when the CEO comes from an industry related firm. These findings support our theoretical arguments that the boards of directors may use a logic or rule of appropriateness in deciding the industrial origin of outside successors.  相似文献

Adults' self-concept of academic ability is discussed within the larger context of self-concept theory, the presence of adults in college, and the sparse research on adult self-concept. The operation of adult self-concept was explored with data gathered from 480 undergraduate students age 25 or older. Adult self-concept of academic ability appeared to operate much as predicted by the theory. It was shaped from past academic activities (credits earned and GPA), and it affected subjective academic outcomes such as "how well one feels he/she is doing in college" and "whether one's goals are being met by the college experience." It also affected objective outcomes such as current credit load carried and grades attained. Self-concept did not vary by race, gender, or income, though it did vary by age. Subdomains of self-concept were explored, and the most important appeared to be interaction skills within the classroom. Relating academic self-concept to other psychological variables showed that it is unrelated to motivation, positively related to global self-esteem, and negatively related to depression, stress, and external attributions for academic success.  相似文献

This article reviews recent research concerned with the association between combat-related posttraumatic stress disorder (PTSD) and interpersonal functioning, before describing the development of a pilot program established to provide mental health services for Vietnam veteran family members. The results of a brief program evaluation are also presented. Sixty clients provided posttreatment and six-month follow-up data on a variety of outcome measures which were compared with independent ratings returned by 33 therapists. On average, clients reported that counselling had been beneficial and indicated satisfaction with services received. However, at posttest, therapists indicated that approximately 50% of clients were in need of continued treatment. There was a decrease in satisfaction with services over the posttest-follow-up period, but no change on most measures of psychotherapy outcome.  相似文献

This paper has two objectives. Using data from the 2000 census, we develop for each of the 331 metropolitan statistical areas (MSAs) of the United States in 2000 an index of gay male partnering and an index of lesbian partnering. Drawing on the theoretical perspective of human ecology, we propose and test an assortment of hypotheses relating characteristics of the metropolitan areas with the gay male and lesbian partnering indexes.  相似文献

Elder abuse remains a largely hidden problem in our society and only a small minority of victims are connected to formal support/protective services. Healthcare settings have been identified as a critical milieu to uncover cases of elder abuse; however, under-detection in these settings is a major issue. Victimization disclosure is an important component within the overall detection effort, yet it has received little attention in the elder abuse literature. Drawing on relevant literature from other domains of family/interpersonal violence, this article highlights the disclosure process, as well as disclosure barriers, facilitators, and competencies to consider when working with older adults.  相似文献

In response to the very limited and mostly outdated literature on older lesbian sexuality, this exploratory study examined older lesbian sexual identity, romantic relationships, the impact of aging, and experiences of discrimination within these contexts. Utilizing an online survey that recruited via numerous online lesbian communities and snowball sampling, 456 lesbians over the age of 50 responded to closed, Likert scale, and open-ended questions that provided a preliminary understanding of older lesbian sexuality. The results indicated that older lesbians have experienced fluidity in past romantic and sexual relationships, as well as in erotic fantasies, despite strong identification with being lesbian. The findings also indicate a decreased focus on sexuality in the context of relationships, with more focus on stability and continuity. Future research is needed that provides greater specificity and detail about older lesbian conceptions of sexual behavior and sexual identity labels, as well as specific sexual behaviors.  相似文献

In aviation, there is currently a lack of accurate and timely situational information, specifically weather data, which is essential when dealing with the unpredictable complexities that can arise while flying. For example, weather conditions that require immediate evasive action by the flight crew, such as isolated heavy rain, micro bursts, and atmospheric turbulence, require that the flight crew receive near real-time and precise information about the type, position, and intensity of those conditions. Human factors issues arise in considering how to display the various sources of weather information to the users of that information and how to integrate this display into the existing environment. In designing weather information display systems, it is necessary to meet the demands of different users, which requires an examination of the way in which the users process and use weather information. Using Human Centered Design methodologies and concepts will result in a safer, more efficient and more intuitive solution. Specific goals of this approach include 1) Enabling better fuel planning; 2) Allowing better divert strategies; 3) Ensuring pilots, navigators, dispatchers and mission planners are referencing weather from the same sources; 4) Improving aircrew awareness of aviation hazards such as turbulence, icing, hail and convective activity; 5) Addressing inconsistent availability of hazard forecasts outside the United States Air Defense Identification Zone (ADIZ); and 6) Promoting goal driven approaches versus event driven (prediction).  相似文献
