This paper uses in-migration, out-migration, and net migration vectors to measure and portray the migration streams occurring between April 1, 1955, and April 1, 1960, for all persons five years old and over on April 1, 1960, among 38 contiguous state economic areas (SEA's) in Oklahoma, Colorado, Kansas, Missouri, Arkansas, Texas, and New Mexico. Both rectangular and polar coordinates were employed in computing three different types of vector representations. First, migration vectors for each SEA, expressed in total people-miles of in-movement, out-movement, and net movement represent the resultant direction of movement and the total people-miles of movement. Second, in- and out-migration vectors of the total people-miles of movement, with the widths of the vectors drawn proportional to the number of migrants, show the total size of each migration stream for each SEA, the resultant direction of movement, and the distance moved in total people-miles of movement. p ]Third, in- and out-migration vectors of the average distances moved to and from each SEA, with the widths of the vectors drawn proportional to the number of migrants, show the magnitude of movement, the average distance moved per migrant, and the resultant direction of movement. This study shows that migration vectors based upon polar coordinates are more accurate than the migration vectors based upon rectangular coordinates. Also, the in- and out-migration vectors are superior to net migration vectors in representing migratory streams among geographic areas.  相似文献

(1) Comparison of patients with a national sample reveals no difference in income (adjusted for inflation), marital status and education level but patients, who are typically older, are more often retired or disabled. (2) Overall, perceived quality of life is nearly the same for patients and national sample; apparent differences can be readily explained by factors other than cancer or its treatment. (3) While some minor differences among patients were found as a function of their site of cancer, treatment modality, or health status, no evidence was found of significant detrimental effects due to radiation therapy or perceived quality of life. (4) Contrary to expectations of deteriorated quality of life, compared to the national baselines the patients are actually more satisfied with their lives as a whole.  相似文献

This study aims to investigate the relationship between teachers’ demographic variables and burnout in Hong Kong using the Maslach Burnout Inventory. It is found that when compared with the North American normative data, Hong Kong teachers scored in the average range of burnout in emotional exhaustion and personal accomplishment while they scored in the low range of burnout in depersonalization. Gender differences were found in all three burnout syndromes, and teachers who were younger, unmarried, without religious beliefs, less experienced, without finishing professional training and of junior rank were more consistently burned out. Whereas age was the strongest predictor for emotional exhaustion and depersonalization, teachers’ rank is the best predictor for personal accomplishment. However, the effect of demographic characteristics of teachers on burnout is not that salient.  相似文献

“Risk” is a word that has become common currency in the financial services industry in general, and in the pensions industry in particular. This article critically examines its use in the context of the current debate about UK pension reform. “Risk” is used by a broad spectrum of interests to discuss a wide range of pension issues in a variety of contexts. The article outlines key theoretical perspectives on the nature and construction, or conceptualization, of risk. Their relevance to debate and policy initiatives, particularly public pension policy, is examined. It is suggested that current government policy is failing to carry with it those to whom the policy applies; that reforms implicitly, if not explicitly, underestimate the importance of “security”; and that failure to conduct a much broader debate about the fundamental notions of work, retirement, saving and security may simply condemn the UK to interminable pension reform.  相似文献

We develop a model of experimentation and learning in policymaking when control of power is temporary. We demonstrate how an early office holder who would otherwise not experiment is nonetheless induced to experiment when his hold on power is temporary. This preemptive policy experiment is profitable for the early office holder as it reveals information about the policy mapping to his successor, information that shapes future policy choices. Thus policy choices today can cast a long shadow over future choices purely through information transmission and absent any formal institutional constraints or real state variables. The model we develop utilizes a recent innovation that represents the policy mapping as the realized path of a Brownian motion. We provide a precise characterization of when preemptive experimentation emerges in equilibrium and the form it takes. We apply the model to several well known episodes of policymaking, reinterpreting the policy choices as preemptive experiments.  相似文献

This paper explores the role of within group social comparisons on the life satisfaction of different racial and ethnic groups in the US. For Whites, we find that higher group income levels are associated with lower levels of life satisfaction, a result that is consistent with a preference for within group status. In contrast, life satisfaction is increasing in group income for Blacks. This result is consistent with the existence of social norms that emphasize Black solidarity. It is also consistent with an information effect in which Blacks rely on peer income levels to form expectations regarding their future prospects. We introduce a theoretical framework to help to distinguish between solidarity and information effects. Our empirical results provide strong support for the hypothesis that solidarity rather than information accounts for the positive relationship between average Black income and the subjective wellbeing of US Blacks. Finally, we consider two theories of social solidarity and find support for social salience but not social density in determining the strength of solidarity effects.  相似文献
