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

Shifts in the American political landscape during the 1980s had impacts on aging policy and on the behavior of aging interest groups through that decade. But perhaps even more important are the likely effects of those changes on aging policy and on the roles of age-related groups in the 1990s--and probably beyond. First, some of the major policy trends of the 1980s are sketched out, especially the renewed emphasis on federalism. Then, an assessment of their effects on aging policy and aging interest groups is provided. Next, a rationale for focusing on state-level policy and a discussion of current aging interest-group mobilization at the state level are presented. Last, the prospects for aging interest-group influence in the 1990s--a period in which the prior decade's emphasis on dual federalism is likely to continue--is addressed.  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
