Amanda Sives 《International migration (Geneva, Switzerland)》2012,50(1):113-128
In common with many other developing states, the Jamaican government has recently sought to institutionalize relations with its diaspora in order to enhance its development potential. I explore the initiative in this paper. I begin with a definition of diaspora, in which I argue for the need to recognize the multiple meanings of the term, especially as they relate to migrant communities that do not follow the pattern of forced migration. Using Itzigsohn’s distinction between “narrow” and “broad” formations (see Itzigsohn et al., 1999 ), I argue that analysis of the operation of diaspora–state relations can only occur meaningfully using the narrow definition. This is followed by an examination of recent literature on diaspora–state relations, which provides a necessary context for the Jamaican case study. In the second section, I provide background to the 2004 initiative, showing that there was a clear progression from concern about the experiences of returned residents to an engagement with Jamaicans residing overseas. In the third section, I examine the structures created by the Jamaican government and, finally, I provide a critical appraisal of the process as it has unfolded thus far. I argue that tensions remain regarding the role and functioning of the “new” formalized process compared with the pre‐existing bodies, that resources are required to ensure a more equitable functioning of the process and that questions remain about the extent to which the new bodies “represent” the diaspora. 相似文献

A conceptual framework for examining the promise of the NORC program and Village models to promote aging in place 总被引:1,自引:0,他引:1

A growing paradigm shift emphasizes efforts to promote aging in place not only by helping aging individuals and families, but also by addressing and engaging communities. This paper explores the idea of developing community supports for aging in place by examining two models that incorporate this approach into practice: Naturally Occurring Retirement Community Supportive Service Programs (NORC programs) and Villages. Drawing on research regarding social–relational aspects of communities and later-life health and well-being, we present an integrative conceptual framework positing three categories of activities and services (civic engagement and empowerment activities; social relationship building activities; services to enhance access to resources)–as well as the initial outcomes and intermediate outcomes–through which the NORC program and Village models potentially achieve their long-term goal of promoting aging in place. Based on this framework, we conclude with directions for future research on community initiatives that support aging in place. 相似文献

Stable housing is widely recognized as a prerequisite for the functioning of individuals and families. However, the housing stability of fathers is understudied, particularly for fathers living apart from their children. This analysis measures the extent and nature of fathers' housing insecurity using the Fragile Families and Child Wellbeing Study, a national longitudinal survey of urban families. Housing insecurity affects a substantial portion of fathers, with 25% experiencing insecurity at least once in their child's first 9 years. However, few fathers report persistent insecurity that spans consecutive waves. Data also indicate significant differences in rates of housing insecurity between fathers living with, and apart from, the mothers of their children, with nonresident fathers far less likely to report secure housing and more likely to experience incarceration. The nature of insecurity experienced by nonresident fathers is also qualitatively different than that experienced by their coresident counterparts. 相似文献

A fatigue-related decrease in quality and accuracy of the proprioceptive feedback from muscle spindles in the back (e.g. stretch reflexes) may lead to a deterioration of spinal stability, thereby making the spine more vulnerable to external perturbations. Endurance time, tissue oxygenation, reflex latency and blood pressure response were studied in twenty subjects during a submaximal endurance test of the back extensors (20 % MVC) performed as either a position task (supporting a weight stack while maintaining trunk position) or a force task (exerting a force against a dynamometer). Mean endurance time was 8.91 (± 2.79) min for the force task and 10.86 (± 6.93) min for the position task. This result is in striking contrast to what has previously been reported from limb muscles, and suggests that back muscles are especially well suited for postural tasks. An increased reflex latency found after the position task indicates that the disadvantage of the prolonged endurance time is a deterioration of the afferent input from the muscle spindles that may potentially hamper the protection of the spine. 相似文献

Shift workers from control centers of electrical systems are a group that has received little attention in Brazil. This study aimed to compare workers' job satisfaction at five control centers of a Brazilian company electrical system, and according to their job titles. Method: The Organization Satisfaction Index (OSI) questionnaire to assess job satisfaction was used. ANOVA was used to compare OSI means, according to job title and control center. The results showed that there is no difference in job satisfaction among job titles, but a significant difference was found according to the control center. A single organizational culture cannot be applied to several branches. It is required to implement actions that would result in job satisfaction improvements among workers of all studied control rooms centers. The high level of education of operators working in all centers might have contributed to the similar values of perceived satisfaction among distinct job titles. 相似文献

Background and methodology Sociodemographic trends mean increasing numbers of new relationships in later life. These trends may not only have health consequences for women and health services but also impact on the targeting of sexual health messages. This study aimed to examine attitudes and knowledge surrounding contraception, sexual health and unwanted pregnancy among those accessing the website www.menopausematters.co.uk. A voluntary online survey was completed. RESULTS: Survey was completed by 550 respondents. Three hundred and sixty-six women, 94% of whom self-classified as pre- or perimenopausal, had been sexually active with a male partner in the previous four weeks. Commonest contraceptive methods used by perimenopausal and postmenopausal women were condoms, combined oral contraceptive pill (COCP) and male sterilization. Up to 42% of women surveyed were unhappy with their contraception. A total of 27% premenopausal, 32% perimenopausal women and 40% postmenopausal used no contraception. One-third of women were unhappy about this and 19 unplanned pregnancies had occurred. The majority of women were informed regarding COCP use over 35 years, hormone replacement therapy, emergency contraception and ceasing contraception. The majority of women were unaware that more terminations of pregnancy are performed in women over 40 than any other age group per total pregnancies.Almost a third of women were unaware that chlamydia incidence is increasing in older women. Most would use condoms in new relationship. Discussion and conclusions Women accessing www.menopausematters.co.uk are well informed about contraception and sexual health. The majority of those accessing the site are sexually active, but many use no contraception, or are unhappy with their chosen method, leaving them vulnerable to unwanted pregnancy or sexually transmitted infection. 相似文献
