The influence of mumber and ages of children on residential mobility   总被引:1,自引:0,他引:1  
Larry H. Long 《Demography》1972,9(3):371-382
Married couples without children are more geographically mobile than those with children, at least through age 45. Among husband-wife couples with children, ages of children exercises a consistent mobility differential; when age of family head is controlled for, families with children under 6 years old only are the most mobile both within and between counties, followed by those with children under 6 and 6–17 years old, and followed in turn by families with children 6–17 years old only. The relationship between number of children and the probability of moving within counties has a reverse J-shape for family heads at each age under 45; after age 45 the relationship assumes a more normal J shape. Number of children is inversely related to the probability of migrating (moving between counties) for husband-wife families in which the husband is under 35; after age 35 the relationship is erratic. The effect of ages of children generally holds for each size of family. Female family heads with children are generally more geographically mobile than male family heads (wife present) at the same age and with the same number and ages of children present.  相似文献

Pre-marital counseling purports to help clients discover and challenge unrealistic expectations they may have for themselves and for one another. Rational-Emotive Therapy (RET) is ideally suited to locating and correcting irrational thoughts that precipitate personal and interpersonal conflict. In order to demonstrate the utility of RET pre-marital counseling, this article presents examples of specific irrational beliefs which clinicians can use to help couples develop and maintain intimacy with minimal conflict. Mental health practitioners are encouraged to apply these principles to other specific irrationalities they may discover in their own work experience.  相似文献

We present a general framework to study the project selection problem in an organization of fallible decision-makers. We show that when the organizational size and the majority rule for project acceptance are optimized simultaneously, the optimal quality of decision-making, as determined by the decision criterion, is invariant, and depends only on the expertise of decision-makers. This result clarifies that the circumstances under which the decision-making quality varies with the organizational structure are situations where the organizational size or majority rule is restricted from reaching the optimal level. Moreover, in contrast to earlier findings in the literature that the hierarchy and the polyarchy are generally sub-optimal structures, we show that when the size, structure and decision criterion are simultaneously optimized, the hierarchy and the polyarchy are in fact the only possible optimal organizational structures when decision-making costs are present.

Weight gain and behavioral patterns during college may contribute to overweight and obesity in adulthood. The aims of this study were to assess weight, exercise, and dietary patterns of 764 college students (53% women, 47% men) during freshman and sophomore years. Students had their weight and height measured and completed questionnaires about their recent exercise and dietary patterns. At the beginning of freshman year, 29% of students reported not exercising, 70% ate fewer than 5 fruits and vegetables daily, and more than 50% ate fried or high-fat fast foods at least 3 times during the previous week. By the end of their sophomore year, 70% of the 290 students who were reassessed had gained weight (4.1+/-3.6 kg, p < .001), but there was no apparent association with exercise or dietary patterns. Future research is needed to assess the contributions of fat, muscle, and bone mass to observed weight gain and to determine the health implications of these findings.  相似文献

This paper examines whether differentiating among types of intimate partner violence enhances the explanatory capacity of extant empirical models.The analysis uses national-level Canadian data to evaluate an alternative approach to operationalizing intimate partner violence, drawing upon Black's (1990) and Johnson's (1995) theoretical work. The main argument suggests that current efforts to explain intimate partner violence with victimization studies are inadequate because they typically do not measure key sociological variables. The failure to assess the contexts within which different types of violence occur further hinders explanatory efforts.The paper concludes with recommendations for innovative theoretical and methodological strategies to address these limitations.  相似文献

This study aimed to collect evidence on the structural and substantive validity, and test-retest reliability of the Chinese version of the Oswestry Disability Index (CODI). Seventy-nine patients suffering from chronic low back pain were assessed with the CODI. The results of explorative factor analysis primarily suggested a single-factor structure with nine out of 10 items (factor loading = 0.66-0.79). The sex life item was found to load on a different factor. The Cronbach's alpha of all 10 items was 0.81 (p<0.05). When the sex life item was removed from the analysis, the alpha value was increased to 0.89 (p<0.05). The test-retest reliability was estimated based on 56 participants who completed two administrations of CODI in 48 hours. The intraclass correlation coefficient (ICC) computed for the total CODI scores was 0.86 (95% C.I. = 0.81-0.91). The reliability estimated for the item scores using Kappa statistics ranged from a high of k=0.80 for the sitting item to a low of k=0.49 for the traveling item. Kappa statistics were not available for three items. The Chinese version of the Oswestry Disability Index demonstrated satisfactory validity and test-retest reliability, and so could be considered as an appropriate instrument for assessing chronic back pain-related disability in Chinese patients in Hong Kong. Further research should address the cross-cultural and measurement issues in regard to sex life in order to further improve the test content of the instrument.  相似文献

It has long been recognized that gambling is an activity that is often combined with alcohol intake. Not only do the behaviors of drinking and gambling frequently co-occur, alcohol use disorders and pathological gambling are also commonly co-morbid conditions in both clinical and non-clinical samples. This article introduces a special issue of the Journal of Gambling Studies focusing on cutting edge findings on the relations between gambling and alcohol use behaviors and their associated disorders. We set the stage for the following series of six novel empirical papers and integrative commentary by reviewing the theoretical pathways through which alcohol use and gambling disorders may be linked. We conclude by describing some of the novel contributions of each of the empirical studies from within the context of these theoretical models.  相似文献

The spark of small groups: An analysis of the developmental logic and dynamics of a consultancy process In the recent past large group interventions have gained increased attention in the systemic consulting literature. In contrast to this tendency, this paper focuses on the significance and effectiveness of small group interventions in business consultancy.Based on a qualitative analysis of a consultancy process, the effectiveness of small group change processes is documented here: Unlike large groups, small groups not only are far more likely to succeed in developing structures which differ from the existing organizational structures, they moreover are much more likely to develop a strong identity which helps them generate the power necessary for change. Especially in conflict situations and in situations where the pressures that are being put on an organization are increasing, small groups are more likely to maintain their identity, another crucial prerequisite for the initiation of a change process.The paper shows that consultancy systems, which differ in structure from the customer organization, are apt to serve as incubators for the development of strong groups within an organization. These small groups are able to push for organizational changes using conflicts process.  相似文献
