Albania is a country on the move. This mobility plays a key role in household‐level strategies to cope with the economic hardship of transition. With the relaxing of controls on emigration at the beginning of the 1990s, international migration has exploded, becoming the single most important political, social, and economic phenomenon in post‐communist Albania. Based on the 1989 and 2001 population censuses we estimate that over 600,000 Albanians live abroad, mostly in nearby Greece and Italy, with the vast majority coming from a limited number of districts located at the coastal and transport gateways to these destination countries, as well as Tirana. The available data also suggest that a similar number have considered migrating, and of these, half have tried and failed. Almost one‐half of the children who since 1990 no longer live with their parents are now living abroad, a number of almost exodus proportions. This article also identifies clear patterns of temporary migration, with Greece being by far the most important destination and rural areas from the Center and North‐East of the country being the primary origins of these flows. Although migration, with the resulting remittances, has become an indispensable part of Albanian economic development, there is increasing consensus on the necessity to devise more appropriate, sustainable strategies to lift households out of poverty and promote the country's growth.  相似文献

There are more than 17,000 nursing homes in the United States providing care for 1.7 million disabled and elderly individuals. Medicare and Medicaid paid $28 billion in 1997 for nursing home services, more than one half of all nursing home expenditures. Improvements in the quality of care in these facilities and ensuring value for public expenditures has been a long sought after goal. Recent actions by the federal government are designed to strengthen state and federal authority and processes to accomplish this goal. Physician leadership in this area is essential to its success.  相似文献

I consider the role of unions in fostering electoral participation in the U.S. Using aggregate and individual data, I argue that turnout varies directly with the organizational strength of unions, not only through their ability to mobilize their own members per se, but also, and more importantly, through their ability to affect the rate of participation of voters in general. My results imply that unionization helps explain much of the post-1960 decline in voter turnout. The magnitude of the relationship is demonstrated to rival that of more conventional determinants of voter turnout such as education.  相似文献

As a result of the intensification and globalization of competition in most fields, the use of competitive intelligence (Cl) in strategic decisions has grown in potential importance. Yet evidence exists that many companies have serious blind spots concerning their competitors' capabilities, intentions and possible reactions to offensive moves. This article introduces a relatively simple but systematic approach to identifying and studying competitive blind spots and facilitating the effective use of Cl in strategic decisions. Applying this approach retrospectively in two companies, and prospectively in a third, we found that if identified serious gaps in Cl, which, in all cases, may have contributed to results shortfalls.  相似文献

The purpose of the current study was to examine whether the effects of social support on physical exercise in older adults depend on individual perceptions of self-efficacy. Three hundred nine older German adults (age 65-85) were assessed at 3 points in time (3 months apart). In hierarchical-regression analyses, support received from friends and exercise self-efficacy were specified as predictors of exercise frequency while baseline exercise, sex, age, and physical functioning were controlled for. Besides main effects of self-efficacy and social support, an interaction between social support and self-efficacy emerged. People with low self-efficacy were less likely to be active in spite of having social support. People with low support were less likely to be active even if they were high in self-efficacy. This points to the importance of both social support and self-efficacy and implies that these resources could be targets of interventions to increase older adults' exercise.  相似文献

This article combines relational perspectives on gender identity with social network structural perspectives on health to understand men's sexual functioning. The authors argue that network positions that afford independence and control over social resources are consistent with traditional masculine roles and may therefore affect men's sexual performance. For example, when a heterosexual man's female partner has more frequent contact with his confidants than he does--which the authors refer to as partner betweenness--his relational autonomy, privacy, and control are constrained. Analyses of data from the National Social Life, Health, and Aging Project (NSHAP) show that about a quarter of men experience partner betweennessa and that these men are 92% more likely to report erectile dysfunction. Partner betweenness is strongest among the youngest men in the sample, which may reflect changing conceptions of masculinity in later life. The authors consider several explanations for these findings and urge additional research on the links between health, gender, and network structure.  相似文献

The current study used latent profile analysis (LPA) to examine the implications of fathers' experiences of work stress for paternal behaviors with infants across multiple dimensions of parenting in a sample of fathers living in nonmetropolitan communities (N = 492). LPA revealed five classes of fathers based on levels of social–affective behaviors and linguistic stimulation measured during two father–infant interactions. Multinomial logistic regression analyses suggested that a less supportive work environment was associated with fathers' membership in multiple lower quality parenting classes. Greater work pressure and a nonstandard work schedule also predicted fathers' membership in the latent parenting classes, although these associations differed depending on the number of hours fathers spent in the workplace.  相似文献
