It is estimated that approximately 1,000,000 elderly men care for spouses with Alzheimer's disease or other forms of cognitive impairment, yet we have only a limited understanding of their work, and central questions arise. What do men caregivers do, and what meanings do they ascribe to their work? What are their distinctive strengths and vulnerabilities, and what can we learn about men and caregiving from their stories? This qualitative study was based on in-depth, open-ended interviews with 14 elderly men who are primary caregivers to wives with dementia. All interviews were taped, transcribed, and manually coded. The resulting information then underwent analysis from which three major themes emerged: feelings of isolation and invisibility of their care work, a style of caregiving that jointly utilizes management and nurturing, and feelings of commitment, responsibility, and devotion.  相似文献

Bootstrap tests: how many bootstraps?   总被引:3,自引:0,他引:3  
In practice, bootstrap tests must use a finite number of bootstrap samples. This means that the outcome of the test will depend on the sequence of random numbers used to generate the bootstrap samples, and it necessarily results in some loss of power. We examine the extent of this power loss and propose a simple pretest procedure for choosing the number of bootstrap samples so as to minimize experimental randomness. Simulation experiments suggest that this procedure will work very well in practice.  相似文献

We use data from the 1931, 1941, and 1951 censuses of India and the 1951 census of Pakistan to examine the demographic consequences of Partition in the Punjab in 1947. Had growth rates for the period 1931-41 for the Punjab as a whole continued to 1951, the population of the Punjab would have been 2.9 million larger than that recorded in 1951. Population losses from migration and mortality above age 20 were approximately 2.7 million greater between 1941 and 1951 than would have been predicted by loss rates between 1931 and 1941. We estimate a net Partition-related population movement out of the combined Punjab of about 400,000. We conclude from several lines of analysis that Partition-related population losses in the Punjab, either from deaths or unrecorded migration, were in the range 2.3-3.2 million. Partition was also marked by a dramatic religious homogenization at the district level.  相似文献

This essay integrates approaches from three literatures to develop a model of leader development. Kanfer and Ackerman's (1989) episodic model of skill acquisition is combined with Kegan's approach to adult development to encompass development of transactional and transformational leadership. Importantly, feedback mechanisms are added to explain changes in individuals'intellectual capacities, values, and beliefs over time. This framework provides a summary of what is known about the processes underlying developmental change in how leaders understand and act on their environment and provides specific directions for future research.  相似文献

The body of research that has attempted to identify and characterize the “ecologically concerned” or “socially responsible” consumer is challenged for its assumption that this is a single group sharing a general disposition to conserve. Based on a comparison of gasoline and home heating energy conservers from a single sample, evidence is provided that these are two unique groups and that those who are conservers in both areas form a third unique group that is closer to the original notion of a generalized conservation ethic. Implications are discussed for future research focusing on energy conservation and social responsibility.  相似文献

A 1024 CPU parallel computer is used to obtain simulated genotypes in the Tristan da Cunha pedigree using random local updating methods. A four-colour theorem is invoked to justify simultaneous updating. Multiple copies of the program are run simultaneously. These results are used to infer the source of the B allele of the ABO blood group that is present in the population.  相似文献

The recognition of overseas qualifications in Australia continues to be a major problem experienced by migrants, either through a lack of adequate verifiable documentation, difficulties in determining parity with local qualifications, or through problems associated with accrediting experience subsequent to basic training. Rather than the valuation of formal paper qualifications, it is suggested that the skills currently held by the migrant be assessed. The assessment of skills is a more productive and equitable model and should be developed, especially in the context of a dynamic labour market and of a greater emphasis being placed on skills in Australia's immigration policy.  相似文献
