A generalization of Petersen's typology of migration

A typology of migration is presented that extends the one originally developed by William Petersen, which was based on ecological push, migration policy, people's aspirations, and social momentum. The proposed typology considers both the migrant's state of mind and two points in time. Examples of 36 migrant types are provided using data for Canada and selected other countries.

宗教象征艺术

一、森林之歌在扎伊尔的艾图瑞(Ituri)森林中,特恩布尔·科林(Coin Turnbull)和巴姆布蒂(Bambuti)人一起生活了一个阶段,他们属于矮种人.特恩布尔·科林把自己的感受写成《森林人》一书.这本书中,我最喜欢的一些事情,可能有助于阐述自己对无文字民族宗教象征艺术的性质的看法.这些事情,发生在要举行仪式之前的几个月中.每晚上,矮人燃起一堆专门的营火,他们集拢在火堆周围,且歌且宴.他们唱的歌直接与森林有关,把森林看作是他们的供养者,一种实体或特别是在这种场合存在于他们知觉中的神.森林以动听的歌回报他们,歌声从营地四周森林的各个位置发出,响彻夜空,终夜不绝入耳.森林之歌产生于熟练的喇叭筒游戏.这种仪式和吼声器,统称为"莫里莫"(Molimo).     

Retiree medical plan design: determining the philosophy, communicating the need

Much has been written, both in benefit-related journals and in the general press, about the recent statement, FAS 106, issued by the Financial Accounting Standards Board (FASB). This statement requires most employers to begin accounting for retiree health care benefit costs for active employees as well as current retirees, creating a significant negative financial impact. Most of the attention has been focused on getting the numbers that will tell the extent of the impact resulting from FAS 106. The next step has been to review retiree medical coverage to see how the affected companies can change it to reduce their liability. Although the urge is strong to adopt a quick-fix solution, employers can greatly benefit by reviewing their benefit philosophies and making plan decisions that make sense for them. This article discusses key questions that can help focus the issue on company philosophies and lays out a framework for determining suitable plan designs that can also help companies manage the retiree medical liability.     

Optimal pension funding with demographic instability and endogenous returns on investment

This paper tries to explore some optimal funding policies for pension systems in a general equilibrium setting where funding affects returns on investment and wages through its impact on capital formation. This is done in the context of irregular demographic evolutions such as those expected in developed countries for the next century. Particular attention is given to the intergenerational welfare criterion which is used for designing optimal policies. It appears that funding receives low justification with a welfare criterion which assumes a high substitutability between consumptions of successive cohorts, implying a low concern for intergenerational equity. Funding is highly justified in the opposite case where a high level of consumption for some cohorts is not considered as a compensation for low consumption by others. However the optimal patterns of transfers and savings which are found in this latter case are not straightforward. Some simpler funding rules are explored in the last section of this paper, which show that non-optimal funding may imply, on the contrary, a high level of inequality between subsequent generations.Paper presented at the ISPE-conference Fiscal implications of an ageing population, May–June 1990 at Vaalsbroek, The Netherlands.

Survey provides overview of profession's responsibilities

At the end of 1990, the Physician Executive Management Center, Tampa, Fla., undertook a survey of College members to determine levels of compensation and benefits and to provide a glimpse at the roles and responsibilities of physician executives. The results of the survey have recently been published by the Management Center. In this article, the roles and responsibilities of physician executives for the overall sample are summarized.     

Making room for alternatives

Alternative healing is an idea whose time has come, and 1993 was the critical year for that recognition. So believes internist David Edelberg, founder of the Chicago Holistic Center. There patients can see one of four allopathic physicians as well as practitioners in 37 additional therapies, including acupuncture, infant massage, homeopathy, nutrition counseling, and Ayurvedic medicine.     

Clinical reengineering. A benchmark strategy

The health care provider marketplace continues to undergo dramatic changes with the advent of hospital mergers, acquisitions, and physician and hospital alliances. In this era of managed care, cost containment is still vital to a hospital's success, but many stakeholders--patients, employers, and physicians--are determined that quality of care also remain paramount. How can hospitals reduce their expenses and maintain a quality focus? The answer lies in a successful clinical reengineering initiative. One progressive model of clinical reengineering is presented, as well as examples of initiatives at three health care institutions. Initial results of clinical redesign programs have been dramatic and encouraging, with documented evidence of simultaneous cost savings and improved patient care.     

Demographic transition theory

Demography is a science short on theory, rich in quantification. Nevertheless, demography has produced one of the best documented generalizations in the social sciences: the demographic transition. What is the demographic transition? Stripped to its essentials it is the theory that societies progress from a pre-modern regime of high fertility and high mortality to a post-modern regime of low fertility and low mortality. The cause of the transition has been sought in the reduction of the death rate by controlling epidemic and contagious diseases. Then, with modernization, children become more costly. Cultural changes weaken the importance of children. The increasing empowerment of women to make their own reproductive decisions leads to smaller families. Thus there is a change in values, emphasizing the quality of children rather than their quantity. In short, the fertility transition is becoming universal phenomenon, in which every country may be placed on a continuum of progress in the transition.
