Fletcher KB 《Nonprofit management & leadership》1992,2(3):283-293
There is growing recognition in the nonprofit field that the executive director has a key role in determining whether the board of directors will function effectively. To aid executives in this vital role, two recent studies defined a "good board" from the point of view of two samples of executive directors of community agencies, then sought factors related to board performance as measured by this definition. In interviews, executives whose boards scored higher than their peers on this performance measurement related how they work with their boards in such areas as recruitment of new members, financial management, fundraising, and leadership development. 相似文献

The paper provides an empirical analysis of saving and consumption choices of the elderly in Germany, based on the German income and expenditure surveys 1978 and 1983. Main feature of these data is the large sample size making it possible to analyze saving and consumption patterns of the very old (aged 75 and above).The observed age-consumption profiles are very different from those predicted by the pure life-cycle theory. Although wealth is declining between age 60 and 70, it increases again after 70, such that the very old have the highest savings rates among all age groups and accumulate wealth rather than decumulate it. These profiles are not confounded by cohort effects and mortality differences. The corresponding expenditure data suggest the following explanation: due to the generous German pension system and the almost complete coverage of health expenses by the mandatory health insurance in Germany, the declining consumption n very old age cannot exhaust the annuity income of the elderly such that wealth is being accumulated in old age.Research in this paper was supported by the National Institute on Aging, grant no. 3 PO1 AG05842-01. I appreciate the helpful comments by Doug Bernheim, Angus Deaton, Daniel McFadden, Jonathan Skinner, Konrad 'Stahl and David Wise, and two anonymous referees. I am indebted to Hermann Buslei and Johannes Velling who provided most valuable and able assistance. 相似文献

Employers are more readily realizing that a nonsmoking policy in the workplace is a more effective way to run their businesses. They are recognizing costs such as productivity losses, increased health and life insurance costs, employer liability for diseases jointly linked to smoking and occupational exposures, absenteeism, passive smoking-induced health care costs among nonsmokers, workers' compensation, and fire losses. Concomitantly, employees are supporting policies that limit smoking to achieve a clean air environment. Former Surgeon General Koop's goal of "a smokefree society by the year 2000" is being recognized by more and more segments of society. 相似文献

The day-to-day management of medical practice is so heavily influenced by tactical imperatives that few physicians have the time to think strategically. Traditionally, the difference between tactics and strategy is not a major concern of most physician executives. The realm of tactics is the short run, when managers must make do with the fixed resources at hand. Strategy addresses the long run, when all resources and markets are variable. A tactical focus is understandable, maybe even acceptable, in industries where nothing challenges traditional approaches to production of an established product or service. However, medical care in the 1990s is changing so fast that a physician executive must devote an incredible amount of time and effort just to stay confused about what is going on. 相似文献

"This study compares the fertility patterns of foreign-born and native-born women in Canada and examines whether [the] same set of social characteristics accounts for differential fertility among both the groups. The study also assesses the importance of social characteristics and assimilation on immigrant fertility behavior. Two generations of currently married/cohabiting women with spouse present are analyzed using multiple regressions. The results reveal similar effects on fertility of social characteristics for foreign-born and native-born, while in the case of younger generations the effects are stronger." 相似文献

Adolescents' social behaviors remain a mystery to parks and recreation providers. Adolescence is a "high-risk" time for all youth in terms of experimenting with potentially health-compromising behavior, whether alcohol, drugs, or sex. Most of these antisocial behaviors occur during adolescents' leisure time. These inferences gave impetus to this research effort. The study was designed to ascertain information on adolescents' preferences for pleasure: drugs or recreation. Data were collected from a sample of 100 high school students from a medium-sized college town, and 100 students from a rural town in Florida. Findings revealed four statistically significant associations in the motives or pleasures sought in recreation and in drug behaviors: "enhancement of popularity," "provision of a means for self-discovery," "achievement of personal goal," and means to rebel against parents. In reference to the latter motive, findings revealed that neither drugs nor recreation were used to rebel against parents. Findings also provide documentation of the value of recreation in insulating adolescents against many of the stressors of contemporary life. 相似文献

The authors examine the present conditions of 26 small, isolated populations living in the north of Russia. The total size of the population under consideration is 181,600, according to the 1989 Soviet census. The conclusion is that these populations are under severe threat of extinction and that there is no consensus about how to resolve their present predicament. 相似文献

This research note briefly outlines International Labour Organization concerns about return migration in developing countries, research being done in the field, and activities in related fields. Attention is being focused on the following topics and areas of study: 1) recommendations and conventions which cover workers generally and migrant workers particularly; 2) measures to avoid the departure of skilled workers from developing countries; 3) special problems encountered in improving migrant professionals' working conditions; 4) developing a central pool of information on labor markets and employment at the international level; 5) bilateral or multilateral migration agreements to optimize the flows of health personnel, scientific workers, engineers, and high level technicians, protecting their rights, and facilitating their reintegration into the country of origin; 6) creating a compensation scheme for skill outflows and training substitutes to fill the gaps left behind by migration; 7) classifying migratory policies adopted by developing countries; 8) reattraction of needed skills to developing countries of origin; 9) transfer of know-how through expatriate nationals; 10) labor reinsertion patterns of migrants returning to Greece, Italy, Portugal, and Spain; 11) Socioeconomic reintegration of migrants returning to Pakistan and Uruguay; and 12) Sri Lanka's experience with self-employment schemes for returned migrants. 相似文献
