Job market signalling (via education) models assume workers know their marginal productivities before accepting jobs, but employers do not. Yet modern theories of the firm predict positive cross partial derivatives among factors. Factor owners thus cannot know their marginal products before interacting with others. Any empirical claim that education is being used for socially wasteful signalling is therefore suspect. Exceptional but underpaid workers can in any case shirk down to the common level instead of obtaining education. The recent finding that minimum wage laws could curb wasteful signalling might thus be a solution in search of a problem.  相似文献

To what degree do individuals adapt their work environments in response to occupational stress? The research reported below addresses this question through a qualitative questionnaire survey that assesses the extent to which innovation is used as a stress coping strategy amongst health care professionals (community and hospital nurses, administration workers and paramedics; N = 333). Overall, 32% of these workers reported a coping response subsequently coded as innovative, and significant between-occupational group differences in the frequency of usage were found. Overwork, procedural difficulties and dealing with others were the stressors eliciting the greatest number of innovative coping responses. The study indicated that such responses were perceived as an effective and important way of dealing with occupational stress. It is concluded that stress management programmes that encourage individuals to change workplace factors through innovation, would be a worthwhile addition to interventions that emphasize individual adaptation to stressful work environments.  相似文献

Planning for care of the Elderly has to face the problems of an increasing elderly population; a wide range of alternative ways of caring for them (at widely differing costs); the fact that services are provided by several different organisations all facing difficult financial constraints; a range of professional opinion about the desirability or otherwise of alternative patterns of care and use of resources; a lack of data on how care is at present distributed; the lack of a structure for organising such data as are available; and the lack of an appropriate computer-based model for manipulating the large number of data elements necessary to describe and help to evaluate alternative plans for the future. The Balance of Care approach to the Joint Strategic Planning of Health and Social Services provision for the Elderly, is being used in pilot applications in two Areas in the UK. Its contribution to the solution of the problems outlined above is described by authors from the two Areas. The approach and the underlying model can be extended to strategic planning for other client groups requiring non-acute care.  相似文献

Since the 1960 Census, Demographic Analysis (DA) has been used by the Census Bureau to evaluate the coverage of the population. Administrative statistics on births, deaths, immigration and Medicare enrollments as well as estimates of legal emigration and net undocumented immigration are used to produce demographic analysis estimates of the population for the census date. These estimates are compared to the Census 2000 data to evaluate coverage in the census. The results are also compared to measures of undercount obtained from dual system estimation. The DA measures substantial reduction in net undercount in Census 2000 compared to 1990. The reductions occur among all demographic categories: all broad age groups, males and females, Blacks and Non-Blacks.  相似文献

This study explored relationships among young adults’ wealth and entrepreneurial activities with emphasis on how these relationships differed among racial and ethnic groups. Using data from the 1997 National Longitudinal Survey of Youth, results indicated that young adults’ (N = 8984) higher accumulated amounts of wealth were associated with pursuing self-employment at higher rates; however, differences emerged when the associations were explored with various types of wealth and within racial and ethnic groups. Black young adults’ greater debt and net worth were associated with their increased likelihoods of self-employment. Among Latino/a young adults, greater liquid assets and net worth were associated with increased likelihoods of self-employment. Wealth was unrelated to white young adults’ self-employment. Wealth appeared to play an outsized role in the self-employment of black and Latino/a young adults compared to that of their white counterparts. In other words, racial and ethnic minority young adults may have a heavier burden for generating their own capital to embark on entrepreneurial activities when mainstream credit markets are unresponsive or inaccessible. Policy implications are discussed.  相似文献

Learning to walk expands infants’ access to the physical environment and prompts changes in their communicative behaviors. However, little is known about whether walking also shapes infants’ proximity to their adult social partners during everyday activities at home. Here we followed 89 infants (42 boys, 47 girls; 92% White, not Hispanic or Latino) longitudinally and documented connections between infant locomotion and infant-adult proximity on two timescales: (1) across developmental time, by comparing data from a session when infants could only crawl to a later session when they could walk (M walk onset = 12.15 months, range = 8-15); and (2) in real time, by testing whether the amount of time that infants spent in motion (regardless of their locomotor status) related to their interpersonal distance to adults. The developmental transition to walking corresponded to a significant, but modest, decrease in infant-adult proximity. Infants’ moment-to-moment locomotion, however, was strongly related to patterns of interpersonal distance: infants who spent more time in motion spent less time near adults and instigated more proximity transitions, resulting in shorter and more dispersed bouts of proximity throughout sessions. Findings shed new light on how infants’ motor achievements can reverberate across other domains of development, and how changes in infant development that researchers often observe over months arise from infants’ moment-to-moment experiences.  相似文献
