conclusion Over the past 30 years, progressive human resource policies and government regulation of the workplace have improved working
conditions. Today unions are no longer exercising union power to“protect the underdog” or “level the playing field” (Kaufman,
2005). Unions are using their power to pass legislation to benefit their narrow special interests. There are two groups in
the workforce that may provide unions with organizing opportunities. One segment of the workforce is the growing number of
nonpermanent employees or contingent workers. Another is the growing low-wage part of the service sector. The Service Employees
International Union has been one of the few unions to expand membership among these employees. The aging of the baby boomers
will raise the demand for service workers in health care facilities and in hotel and office maintenance which will increase
organizing opportunities for unions in this industry (Kosters, 2004). 相似文献

Internal migration from the Peruvian highlands and rural areas has burdened urban areas with rapid growth. Urban expansion
is threatening the desert habitat and unique vegetation communities surrounding Arequipa, one of Peru's largest cities. A
511 ha tract contiguous to the city of Arequipa has been informally designated an ecological park. Analysis of Landsat satellite
imagery over a 16-year interval indicates that urban expansion is occurring in the direction of the park. The land use/land
cover change analysis revealed other landscape patterns and processes, such as agricultural expansion, which are relevant
to the study area. These dynamics, plus principles of landscape ecology, suggest that the park's size and shape may not be
the most suitable. Conservation alternatives include the expansion of the park, the spatial connection to another nature reserve,
or the design of co-management strategies. Given local historical events and the paucity of regional conservation efforts,
social actors in Arequipa and in national governmental institutions will need to find practical ways to collaborate. 相似文献

Let X1,…,Xr?1,Xr,Xr+1,…,Xn be independent, continuous random variables such that Xi, i = 1,…,r, has distribution function F(x), and Xi, i = r+1,…,n, has distribution function F(x?Δ), with -∞ <Δ< ∞. When the integer r is unknown, this is refered to as a change point problem with at most one change. The unknown parameter Δ represents the magnitude of the change and r is called the changepoint. In this paper we present a general review discussion of several nonparametric approaches for making inferences about r and Δ. 相似文献

Training programs committed to the development of culturally competent family therapists must discover ways to raise cultural awareness and increase cultural sensitivity. While awareness involves gaining knowledge of various cultural groups, sensitivity involves having experiences that challenge individuals to explore their personal cultural issues. This article outlines how the cultural genogram can be used as an effective training tool to promote both cultural awareness and sensitivity. 相似文献

Medcamp, a 3-day problem-based career intervention for students entering the 9th grade, implemented each of the 4 antecedents for self-efficacy. Ten boys and 35 girls participated in Medcamp; of these, 35 completed and returned the Medical Career Self-Efficacy Scales (developed by the authors for their study) both at the beginning and at the end of the program. Three scales measured specific self-efficacy (tasks students had performed during Medcamp), related self-efficacy (other tasks students would complete by the second year of medical school), and general self-efficacy (included lifestyle variables and study habits). Results demonstrated significant increases in self-efficacy on all 3 scales. 相似文献

Although sociologists have long been interested in the analysis of inequality, there have been relatively few systematic attempts to measure it. Most measurement has utilized popular existing measures such as the Gini coefficient, which unfortunately is relatively difficult to compute and interpret. This article presents a new measure of inequality (B) that is based upon the concept of entropy. The B measure is used for categorical data and complements Theil's (T) entropy measure for continuous data. The B measure is illustrated for both income and wealth data and successfully meets several criteria for evaluating measures of inequality. These include the criteria of scale invariance, sensitivity to transfers, and adequate upper bounds. A further advantage of sociological entropy measures of inequality is that they facilitate interdisciplinary comparison of work on inequality between sociology and other disciplines (such as economics) which use entropy measures of inequality. 相似文献

A solution for preserving red blood cells (adenine) will make it possible to extend the life of blood from 21 to 35 days. Adenine supplementation may bring dramatic changes in blood outdating and the supply of blood to hospital blood banks. Substantial improvements, however, can be realized only if blood administrators are able to estimate the potential effects of adenine supplementation and set goals based on these projections. Appropriate action could then be taken to reduce blood collection and increase the supply of blood to hospitals. This paper offers a method for blood administrators to estimate the full effects of adenine supplementation and set reasonably attainable goals. Experiences with setting goals for a midwestern U.S. blood region are then discussed. 相似文献
