The contemporary literature on homosexual youth and suicide risk are reviewed in order to delineate the incidence, development, causes/risk factors, and effects of suicidality among homosexual youth. In comparison to heterosexual youth, homosexual youths are more likely to attempt and complete suicide. They confront more challenges in identity development and face more risk factors for suicidality. In some cases, homosexual youths might use suicidal ideation as a means of rediscovering a will to live. 相似文献

The study of character is a legitimate and essential topic for the analysis of leadership in organizations. We undertake three key objectives in this article to stimulate meaningful dialogue. First, a brief historical overview of the extant body of literature on character is provided. Second, working definitions of character and character-based leadership are introduced. Third, new directions for organizational scholars interested in examining the role of character-based leadership in both their research and teaching domains are suggested. 相似文献

Decisions about social media in organizations are not made lightly. Corporate executives are faced with an ever changing and in many cases, uncontrollable opportunity with social media. This study provides insights obtained from 25 interviews with communication and public relations executives to identify their opinions about what drives social media in organizations, what challenges they face, and what questions they have about social media and its measurement. 相似文献

We compare three market structures for monetary economies: bargaining (search equilibrium); price taking (competitive equilibrium); and price posting (competitive search equilibrium). We also extend work on the microfoundations of money by allowing a general matching technology and entry. We study how equilibrium and the effects of policy depend on market structure. Under bargaining, trade and entry are both inefficient, and inflation implies first‐order welfare losses. Under price taking, the Friedman rule solves the first inefficiency but not the second, and inflation may actually improve welfare. Under posting, the Friedman rule yields the first best, and inflation implies second‐order welfare losses. 相似文献

Respiratory illness is an important childhood illness and a significant cause of infant mortality. This study examined the
relationship between neighbourhood level variables and rates of respiratory illness for children less than 2 years of age,
born in Saskatoon between 1992 and 1994. Rates of respiratory illness, as measured by proportion of children hospitalized
and frequency of hospitalization and ambulatory visits to physicians, were higher among infants living in socially disadvantaged
neighbourhoods. Multivariate predictive models for rates of respiratory illness support the research hypothesis that housing
characteristics, in the presence of other neighbourhood characteristics, have a significant impact on determining the rates
of respiratory illness among Saskatoon children. 相似文献

We present a surprising though obvious result that seems to have been unnoticed until now. In particular, we demonstrate the equivalence of two well-known problems—the optimal allocation of the fixed overall sample size n among L strata under stratified random sampling and the optimal allocation of the H = 435 seats among the 50 states for apportionment of the U.S. House of Representatives following each decennial census. In spite of the strong similarity manifest in the statements of the two problems, they have not been linked and they have well-known but different solutions; one solution is not explicitly exact (Neyman allocation), and the other (equal proportions) is exact. We give explicit exact solutions for both and note that the solutions are equivalent. In fact, we conclude by showing that both problems are special cases of a general problem. The result is significant for stratified random sampling in that it explicitly shows how to minimize sampling error when estimating a total TY while keeping the final overall sample size fixed at n; this is usually not the case in practice with Neyman allocation where the resulting final overall sample size might be near n + L after rounding. An example reveals that controlled rounding with Neyman allocation does not always lead to the optimum allocation, that is, an allocation that minimizes variance. 相似文献

Continuums of Care (CoCs) are the primary coordinating bodies for homeless services in the United States. However, the complexities involved in delivering homeless services across interagency networks challenges coordination and system improvement. CoC governance, planning, and service provision have received little attention in academic literature, and thus, Continuums attempt to manage complex systems with little guidance. This evaluation applied community-based system dynamics with homeless consumers and service providers to (1) identify capability traps that impede services delivery and to (2) engage stakeholders in a structured system improvement process. Results revealed organizational structures for governance and planning that inhibit system outcomes. Insights led to policy and practice recommendations for the homeless system. 相似文献
