The occupational adaptation practice model guided the search for and the analysis of the literature on the older worker. The purpose of this literature review was to: identify the occupational challenges that older workers experience, determine ways in which the occupational therapist can promote the occupational adaptation of older workers, and articulate the research and policy changes implied in the model related to health and improved productivity. The analysis of the worker's personal characteristics, work tasks, and environments highlighted the types of occupational challenges that may overwhelm the older worker's adaptive capacity. Straining adaptive capacity of the older worker leads to degradation in levels of mastery. The occupational therapist and others could assist the older worker to achieve relative mastery in response to occupational challenges through ergonomic solutions, training, assistive devices, management policy, and health promotion. Combined efforts of the employer, of the occupational therapist, and of the older work to capitalize on the older worker's years of experience, existing skills, and knowledge facilitates higher job satisfaction, better performance, and an increased sense of well-being in the older worker. 相似文献

Scientists are currently exploring the structure and behavior of complex biological systems, which consist of networks of interacting entities. A recent paper in Proceedings of the Royal Society of London Series B Biological Sciences describes the distinctive characteristics of aging-related proteins in the yeast protein-protein interaction network. In this Perspective, I discuss the implications of these findings for longevity research. 相似文献

The complex Bingham distribution is relevant for the shape analysis of landmark data in two dimensions. In this paper it is shown that the problem of simulating from this distribution reduces to simulation from a truncated multivariate exponential distribution. Several simulation methods are described and their efficiencies are compared. 相似文献

This article addresses issues that develop in the conduct of comparative participant observation research. The two groups
in which the authors became involved as participant observers were the Unification Church of the Korean evangelist Reverend
Sun Myung Moon and the emerging network of organizations involved in the practice of deprogramming. Each group was dedicated
to the destruction of the other. Five major methodological problems, common to conducting investigation on single groups,
are discussed in the context of researching these two antagonistic groups: 1) role definition and justification; 2) pressures
to go native; 3) public pressure to take a stand; 4) evolving commitments; and 5) gaining comparable information and insights.
The authors describe their efforts to resolve these problems and maintain a good rapport with both groups.
This paper is the product of a joint effort. The order of authorship is random and does not imply any difference in the importance
of contributions. 相似文献

In order to carry out the population control policy, efforts are needed to control pregancies and births. Studies show that 3 types of people may deliver babies next year: 1) those who are married at the end of the current year but have not become pregnant, 2) those who have 1 child at the present time and plan to have an additional child for special reasons, and 3) those who may get married during the 1st season of the coming year. Persons from the 1st 2 categories are easy to calculate or estimate. Persons from the 3rd category represent the core in predicting the birthrate for the coming year. Marriage ages and the distribution of dates for marriage are the 2 major sources of information for estimating the total number of persons who belong to the 3rd category. In the 1st step, we need to figure the ratio between the number of marriages in the 1st season and the total marriages for the whole year. Based upon available data for the past 3 years, a formula can be used to calculate this ratio. The marriage numbers for the 1st season of 1982 multiplied by the above percentage will be the possible number of marriages for 1982. Then, the possible number of births can be calculated by taking the birth ratio multiplied by possible marriages for 1982. Using the same method, the possible birth numbers for 1983 can be calculated. The above information shows that the total predicted births for 1983 includes 3 elements: 1) the number of those who aare married but not pregant and plan to give birth in 1983, 2) the number of those who received special permission to have a 2nd child in 1983, and 3) the number of those who may get married in 1982 and 1983 and who may give birth in 1983. 相似文献

Employing certain generalized random permutation models and a general class of linear estimators of a finite population mean, it is shown that many of the conventional estimators are “optimal” in the sense of minimum average mean square error. Simple proofs are provided by using a well-known theorem on UMV estimation. The results also cover certain simple response error situations. 相似文献

The legalization of abortion is still a live issue in Queensland. The numbers and characteristics of women seeking abortion through the Children by Choice Association in 1973–74 and in 1980 were studied since no official statistics on abortion are available. From 1974 to 1980 there was a threefold growth in demand and a threefold rise in the proportion seeking their second or subsequent abortion. Both samples closely reflect the Queensland population as measured by place of birth and religious affiliation. Contraceptive knowledge was found to be associated with education while the proportion who stated they had formal lessons at school rose from 3% to 16% between the samples. In both samples two-thirds of the pregnancies resulted when no physical contraceptive was in use. Social characteristics of the women and men involved were investigated, as well as factors in the abortion decision. 相似文献

The Accuracy of Respondent-Coded Occupation 总被引:1,自引:0,他引:1
This study reports results from a methodological experimentconducted in a national survey to test the accuracy of respondent-codedoccupation. For most uses, we conclude that such measures aresufficiently precise. There are, however, some systematic sourcesof error which the investigator should be aware of. 相似文献
