Much of the analysis of refugee and immigrant adaptation has stressed the interaction of prior experience with the requirements of life in a new country. For refugees, that interaction has often been jarring because of the after‐effects of their flight and their relative inability to prepare for a new life in a new country. Yet refugees have often done rather well in economic terms in that new country. The reasons for that relative success have been phrased in cultural terms (e.g., the predisposition toward education) and in general socioeconomic terms (e.g., refugees as educated and skilled). This article examines a set of factors that lie between these customary cultural and socioeconomic categories. Specifically, the paper examines key features of household formation among Vietnamese refugees. An examination of historical data from southern Vietnam indicates patterns in household formation that appear durable over time yet are not shared across the breadth of Vietnam and cannot thus be viewed as “cultural” in the usual sense. A comparison of the historical data with recent national survey data on refugees in the United States indicates that these patterns continue among Vietnamese refugees and are ‐ as compared to other refugees ‐ distinctive to them. These patterns of household formation provide Vietnamese refugees with important options in adaptation to a new country.  相似文献

There is a need to investigate novel interventions that promote worksite physical activity and wellness. OBJECTIVE: The authors' purpose in this study was to evaluate the effectiveness of a 12-week walking program supplemented with a pedometer, computer educational program, and weekly e-mails. METHODS: College faculty and staff participated in a one-group pre-posttest study to determine whether the 12-week walking intervention had an effect on body mass index (BMI), blood pressure, blood glucose, and cholesterol. The authors also determined participant-perceived wellness effects. RESULTS: The authors observed differences between baseline and follow-up in BMI (p = .024), blood glucose (p = .06), and total cholesterol (p = .09). The program had a moderate effect on fitness, mood, health awareness, nutrition, and health. CONCLUSIONS: It is incumbent that experts develop innovative worksite physical activity and wellness programs. A pedometer-monitored walking program is one way that a worksite health initiative can improve the health and wellness of its employees and simultaneously reduce health-care costs.  相似文献

Background

The prevalence of fear of birth has been estimated between 8–30%, but there is considerable heterogeneity in research design, definitions, measurement tools used and populations. There are some inconclusive findings about the stability of childbirth fear.

Aim

to assess the prevalence and characteristics of women presenting with scores ≥60 on FOBS-The Fear of Birth Scale, in mid and late pregnancy, and to study change in fear of birth and associated factors.

Methods

A prospective longitudinal cohort study of a one-year cohort of 1212 pregnant women from a northern part of Sweden, recruited in mid pregnancy and followed up in late pregnancy. Fear of birth was assessed using FOBS-The fear of birth scale, with the cut off at ≥60.

Findings

The prevalence of fear of birth was 22% in mid pregnancy and 19% in late pregnancy, a statistically significant decrease. Different patterns were found where some women presented with increased fear and some with decreased fear. The women who experienced more fear or less fear later in pregnancy could not be differentiated by background factors.

Conclusions

More research is needed to explore factors important to reduce fear of childbirth and the optimal time to measure it.  相似文献

Abstract

In March 2001 the Canadian National Site Licensing Project (CNSLP) enabled the University of Saskatchewan Library to add over seven hundred electronic titles to its journal collection. The CNSLP titles introduced a critical mass of electronic journals to library patrons, offering a complex and intriguing range of supplementary content and a transformation of the experience of reading scientific journals. This article reports on the plug-ins and add-ons required to access supplementary content in the CNSLP electronic journals and explores the implications of supplementary content for readers.

A class of decisions, asset mix decisions made by pension fund managers, which exhibit characteristics of both programmed and strategic choices is examined in this paper. The decisions are classified using the scheme developed by Mintzberg et al., (1976) to highlight the circumstances under which strategic decisions may be programmed. The types of strategic decisions which lend themselves to programming are considered. The advantages and disadvantages of programming strategic decisions are also discussed.  相似文献

This article presents a consensus-building initiative to develop a statewide research agenda that responds to the needs of Illinois's child welfare community. Researchers conducted this process through a university-community partnership to engage those interested in child welfare services. The process and findings resulted in a living document that will guide child welfare research throughout the state. Findings of the inquiry suggest that the development of best practice models may be one of the most important contributions research can make to practice.  相似文献

Candidate locally D-optimal designs for the binary two-variable logistic model with no interaction, which comprise 3 and 4 support points lying in the first quadrant of the two-dimensional Euclidean space, were introduced by Haines et al. (D-optimal designs for logistic regression in two variables. In: Lopez-Fidalgo J, Rodrigez-Diaz JM, Torsney B, editors. MODA8 – advances in model-oriented designs and analysis. Heidelberg: Physica-Verlag; 2007. p. 91–98). The authors proved algebraically the global D-optimality of the 3-point design for the special case in which the intercept parameter is equal to?1.5434. However for other selected values of the intercept parameter, the global D-optimality of the proposed 3- and 4-point designs was only demonstrated numerically. In this paper, we provide analytical proofs of the D-optimality of these 3- and 4-point designs for all negative and zero intercept parameters of the binary two-variable logistic model with no interaction. The results are extended to the construction of D-optimal designs on a rectangular design space and illustrated by means of two examples of which one is a real example taken from the literature.  相似文献

This article is concerned with the effect of the current economic, political and regulatory climate on the future of health and safety at work. This climate includes a push for increased efficiency and flexibility through industrial restructuring leading to the growth of the secondary labour market of subcontractors, casual labour in increased self employment. Measured against this is the increased regulatory expectations in the area of health and safety including legislation which places major contractors as primarily responsible for all employees on site, whether their own or not. The sets up a potential conflict between the economic and regulatory imperatives. It is this potential conflict which is the focus of concern. The data used to explore the issue are the responses organisations made to a fatality they experienced on a complex industrial worksite. The nature of their response was related to their ideology concerning business success, which was in turn related to the influence they held at the worksite. While these findings tentatively support legislation to increase the responsibility of major contractors, this should not be seen as a panacea. The growth of the secondary labour market as well as the culture of success which motivates large contractors to comply with such legislation is dependent upon the broader economic climate making the a viable success strategy.  相似文献

Abstract To revisit the rural-urban contrast, we use data from non-metropolitan and metropolitan subsamples of the 1985 General Social Survey to test whether, compared to personal networks in urban settings, personal networks in rural settings contain ties of greater intensity and role multiplexity, are based more on kinship and neighborhood solidarities rather than on friendship, are smaller, are denser, and have greater educational, race-ethnic, and religious homogeneity, but less age and gender homogeneity. Our results are generally consistent with these predictions. We then present evidence for rural diversity by comparing data from residents of a two-parish nonmetropolitan area in southwestern Louisiana to the nonmetropolitan subsample of the GSS. After discussing possible mechanisms for this covariation of spatial and aspatial communities, we conclude by commenting on the potential of network analysis to contribute to the resolution of these and other substantively important problems in rural sociology.  相似文献
