This article comprises one facet of a larger, three-year phenomenological study (1997-2000) of gay and lesbian youth coming out in post-apartheid South Africa. A nonprobability sample of 18 young people, aged between 16 and 21 years, was interviewed. The resultant data was content analyzed, and the trustworthiness of the information was ensured via member checking and utilizing an independent coder. Results consistently revealed that gay and lesbian youth use defense mechanisms, such as denial, avoidance, compartmentalization, suppression, compensation, sublimation, undoing, displacement, rationalization, and intellectualization, in a conscious manner during their coming out process. The young people in this study demonstrated resilience despite the prejudice and inner turmoil that they had experienced. Practice guidelines are suggested in terms of how health and social care practitioners can support gay and lesbian youth in coping with their coming out process. 相似文献

Individual‐level census and household survey data are used to present a rich profile of young developing country international migrants around the world. They are found to comprise a large share of the flow of migrants, particularly among migrants to other developing countries, with the age distribution of migrants peaking in the late teens or early twenties. Detailed data are presented on the age and sex composition of migrants, on whether young migrants move alone or with a parent or spouse, on their participation in schooling and work in the destination country, on the types of jobs they have, and on the incidence and age of return migration. The results suggest a high degree of commonality in the youth immigrant experience across a number of destination countries. Recent developing country young migrants tend to work in similar occupations and are more concentrated in these occupations than recent older migrants or young immigrants who arrived at an earlier age. Nevertheless, there is also considerable heterogeneity among young immigrants with respect to school attendance and work in their destination country. The potential of international migration for building human capital is significant but far from being fully used. 相似文献

In this paper, we present and develop the argument that if the survival functions for two population subgroups converge in
later life, a mortality crossover must precede the occurrence of this convergence. Specifically, two survival curves, S
1(x) and S
2(x), associated with two distinct population subgroups, G1 and G2, tend to converge before all members die out, as often observed and anticipated. This convergence leads to an increased mortality
acceleration for the “advantaged” group, and eventually fosters the occurrence of a mortality crossover. We present a mathematical
proof for this relationship and offer several explanations for the mechanisms involved in the process of survival convergence
and the preceding mortality crossover. This new presentation demonstrates that mortality crossover is a highly observable
demographic event given the trend of survival convergence in later life. 相似文献

Recent studies of international inequality have focused mostly on the trend in international income inequality. This article extends the analysis of international inequality to also include inequalities in education and health. Analyses of time-series data for more than 100 countries show that international income inequality declined from 1980 to 2003 as several large, poor Asian countries outpaced many Western countries in national income growth. By contrast, international health inequality followed a U-shaped trend, falling in the 1980s before rising in the 1990s. The turnaround in health inequality coincides with a trend of declining life expectancy in sub-Saharan Africa. International educational inequality experienced the sharpest recent decline, spurred by the global expansion of formal schooling. These findings confirm that there is more to international inequality than income inequality alone and suggest that patterns of inequality in the current era of globalization are likely more complex than many leading theories suggest. 相似文献

This paper describes a conceptually sound and powerful model to aid bank managers in short and long range decision making for the management of the financial performance of the bank. The planning model is a key element in an integrated computer-based planning system which includes a forecast of economic, monetary, and loan market conditions, an analysis of internal relationships, and a system of reports which provide management with access to historical data and planning summaries. The planning model at the heart of the system, contains an imbedded linear programming algorithm to optimize “balance sheet management” decisions within liquidity and capital adequacy constraints. The model recognizes the interaction between assets and liabilities, it recognizes the time value of money, and it accommodates the difference between the net marginal yield for decision making, and the gross average yield used for determining revenue. Finally, the model recognizes the crucial role of liquidity with an important treatment of gross cash flows from normal asset turnover as a major source of liquidity, and the liquidity aspects of liabilities, as well as the more traditional concept of asset marketability. 相似文献

The critical path in a PERT/CPM network is determined in various textbooks by finding the path with associated minimal slack for the network arcs or by finding the path with associated minimal slack for the network nodes. This paper points out that the use of nodes can result in a network path being incorrectly identified as a path of maximum length. 相似文献

This field study provides variables that can be used by practitioners as action levers and by future researchers as the basis for theoretical development. Conclusions from relevant literature and findings from interviews with interdisciplinary research management identified forty variables that were viewed as important to interdisciplinary research project success. After adjusting the data for reliability attenuation, these variables were further analyzed to identify the best prediction equation. The findings suggested that project age or the longevity of the project and open discussion of disagreements were the best predictors of performance. 相似文献

The purpose of the current study was to determine whether brand name can affect the public's evaluation of a product. All subjects smoked identical cigarettes. One group of subjects, however, knew the cigarettes by the name of “Frontiersman,” a masculine name, while the other group knew the cigarettes as “April,” a feminine name. Male and female subjects were asked to rate the cigarette on seven measures. Results show that women gave a more positive evaluation to the cigarette purportedly named “April,” while men gave a more positive evaluation to the identical cigarette when they thought it was named “Frontiersman.” In addition, women reacted more strongly than did men to brand name influence. 相似文献

After a brief review of the role of dummy variables in regression analysis and the current state-of-the art in rounding/truncation error detection in computerized least squares programs, this paper presents a theorem that can be used to detect this type of error whenever an analyst is running a regression program that has one (or more) dummy variables as independent variables. 相似文献
