The development of a survey instrument for measuring the cognitive association of sex, love, and marriage (SLM) is reported. The SLM scale was tested in two phases with two distinct data sets. The first data set comprised the responses of 321 undergraduates at a New England state university. In this first phase, the specific item composition of the scale was determined, and initial reliability and internal consistency were established. The second data set included the responses of 835 undergraduates from three U.S. universities: a Northeastern state university, a Southwestern state university, and a Northwestern state university. In this second phase, additional reliability information was obtained, and the issue of construct validity was explored. By analysis, we judged that the SLM scale is, as expected, significantly related to extramarital sexual attitudes, premarital sexual attitudes, premarital sexual behavior, religiosity, and current relationship involvement. The theoretical significance of SLM association and the possible uses of the SLM scale as a research tool are discussed.  相似文献

This condensed review gives an overview about two methodological approaches to study the impact of physical activity on cognition in elderly, namely cross-sectional studies and randomized controlled intervention studies with pre- and post-measures. Moreover, this review includes studies investigating different types of physical activity and their relation to cognitive functions in older age. Behavioral data are considered but the main focus lies on neuroscientific methods like event-related potentials (ERPs) and functional magnetic resonance imaging (fMRI).  相似文献

The authors examined the relationship between physical activity, exercise, and sedentary behaviors in 493 college students who were enrolled in 10 conditioning activity classes and had completed questionnaires at the beginning of the course. They analyzed sedentary activities and indicators of participation in exercise and physical activity by demographic variables. Surveyed men reported greater participation in physical activity and exercise than did women, and they also spent more time watching television/videos and using the computer. Older students were more likely to report more computer use, whereas younger students scored higher on several physical activity indicators. Of the sedentary behaviors, only computer use for men and television watching for women were negatively correlated with exercise and physical activity. In addition to accessibility and reinforcing properties of sedentary activities, the gender-related relationships between sedentary and active behaviors should be considered in designing interventions to promote exercise in this population.  相似文献

This mini-review summarizes the main associations between physical activity and chronic diseases and discusses the basic concepts related to the role of genetic factors in studies evaluating the effects of physical activity/exercise therapy on chronic disease prevention/treatment during the life course. Many observational cohort studies have shown that high physical activity during young adulthood or middle age is associated with reduced later life morbidity, mobility limitations and mortality. Physical activity or exercise therapy has a positive effect on health via many disease-specific mechanisms. The most consistent finding of the various randomized controlled studies conducted to date is that aerobic/functional capacity and/or muscle strength can be improved by exercise training among patients with different chronic diseases. Genes are known to play a role in chronic disease predisposition and to contribute to physical fitness levels, physical activity participation and ageing. Physical fitness, physical activity and health outcomes may be partly due to underlying genetic factors that have a favourable effect on all these traits (genetic pleiotropy). This means that in observational studies, the relationship between baseline activity and the later occurrence of diseases may not be interpreted entirely as causal. Increased knowledge on the role of nuclear genome, mitochondrial genome, epigenetics, telomeres and regulation of gene expression will increase our understanding of their relationships with physical activity and morbidity.  相似文献

In 2002, the Chinese leadership announced a turnaround in national welfare policy: Local insurance at county level, called the New Rural Cooperative Medical System (NRCMS), was to cover all counties by 2010. This paper addresses the main characteristics of NRCMS as an example of 'transformative state capacity' in decentralised policy fields and its feature 'responsiveness' as a market-based means of its introduction.Reviewing the modes of governance and comparing the introduction of local schemes based on two case studies of western China since 2006, this paper argues that the flexibility shown by local administrators in considering structural and procedural adjustments is the result not only of central directives but also of local initiatives. Forms of locally embedded responsiveness to the needs and perceptions of health care recipients are crucial in enhancing the accountability and responsiveness of local cadres. These new modes of 'responsiveness' or responsive regulation are important in understanding and conceptualising the transformative state capacity. Responsive settings using centrally defined local feedback loops are different from hierarchical control and the formal institutionalised representation of the interests of the local population, and are a rough but effective means of enhancing both flexibility and the efficiency of control and financing by the central state. These feedback loops, which are based on voluntary enrolment and on central state subsidies made dependent on contributions received from participants and local government, are complementary forms of governance at grassroots level.  相似文献

Work/family reconciliation policies can be harnessed to diversepolitical agendas, ranging from feminist-inspired equality strategiesto coercive, neo-liberal programs. In Australia, such policieshave served a range of ends under different governments. Thisarticle focuses on developments since 1996 when the conservativecoalition parties led by John Howard were elected to government.It explores three policy domains that are central to Australia'swork/family agenda: family payments, maternity/parental leave,and child care. Changes in these areas are situated in the contextof the government's broader strategies concerning labor marketflexibility, tax reform, and declining fertility. The articleargues that there has been a substantial retreat from the "femocrat"strategies adopted under Labor in the 1980s and early 1990s.The general thrust of the Howard government has been to discouragelabor force participation of mothers of young children, withthe important exception of sole parents. In a number of areaspolicies are inconsistent, reflecting the government's ambivalenceabout whether to support women as home-based carers, wage earners,or both.  相似文献

This review article provides a thematic synthesis and overview of 30 years of research into the study of men and masculinity in men's magazines. Over 100 articles, book chapters, and books were reviewed to explore how scholars have approached the study of masculinity in such magazines and identify four major areas of inquiry: the commodification of masculinity; the relationship between sexism and misogyny in men's magazines and men's attitudes towards women; the vulnerability of men to, and the role of magazines in the construction of, men's body image anxieties; and the increasing sexualisation of men's bodies. The strengths and potential limitations of these four thematic approaches are identified, including an insufficiently nuanced account of the ways in which men might actually engage with images and ideas about masculinity in such magazines; an overly singular view of male sexuality that naturalises sexist and predatory behaviour; and an overemphasis on men's bodies as sites of vulnerability, risk, or crisis at the expense of more substantive considerations of the relationship between the representation of body modification practices and technologies, and men's embodied identities. The review concludes with an overview of the present field and some suggestions for future research.  相似文献

The purpose of this study was to characterize physical activity (PA) based on survey and ActiGraphy data from older adults at 2 mo post-hip fracture and consider the factors that influence PA among these individuals. The sample included participants from a current Baltimore hip study, the BHS-7. Measurement of PA was based on the Yale PA Survey (YPAS) and 48 hr of ActiGraphy. The sample included the first 200 individuals enrolled in the study, with analyses including 117 individuals (59%) who completed the YPAS and wore the ActiGraph for 48 hr. Half the participants were male, with an overall mean age of 81.3 yr (SD = 7.9). Findings indicate that at 2 mo post-hip fracture participants were engaged in very limited levels of PA. Age and comorbidities were the only variables to be significantly associated with PA outcomes.  相似文献

Unlike other global media products that are imported from overseas, international women's magazines in China are published via licensing agreements or joint ventures with local companies. These ownership patterns allow local editions of international women's magazines to negotiate the tensions and contradictions between the global players and local publishers. Given the influence of cultural and commercial forces in different economic environments, international women's magazines provide a challenging platform for exploring the interaction between global and local forces. Through a theoretical framework of hybridity theory and in-depth interviews with editorial personnel from the magazine industry, this study explores the global and local forces that have contributed to the production process of international women's magazines in China. The findings reveal that these magazines are a result of a multi-level convergence of local realities and global influences. Although there are factors of control and dependence in many areas such as the publishing ideas, editorial policies, the training of personnel, and the quality of production, both Western-style and Japanese-style women's magazines tend to appropriate and rework global cultures to satisfy local readers' needs, albeit in different ways. As a result, local and transnational influences are inextricably interwoven in the production process of international women's magazines in China. The study provides an extensive understanding of the global processes, the consumers, and the cultural forces that are shaping the media, particularly magazines in China.  相似文献

ASSET LEVELS GROWING: In 2010, there was $7.7 billion in health savings accounts (HSAs) and health reimbursement arrangements (HRAs), spread across 5.7 million accounts. This is up from 2006, when there were 1.2 million accounts with $835.4 million in assets, and 2009, when 5 million accounts held $7.1 billion in assets. AFTER LEVELING OFF, AVERAGE ACCOUNT BALANCE DROPS SLIGHTLY: Increases in average account balances leveled off in 2008 and 2009, and fell slightly in 2010. In 2006, account balances averaged $696. They increased to $1,320 in 2007, a 90 percent increase. Account balances averaged $1,356 in 2008 and $1,419 in 2009, 3 percent and 5 percent increases, respectively. In 2010, average account balances fell to $1,355, down 4.5 percent from the previous year. AVERAGE ROLLOVER DECLINES, WHILE TOTAL ROLLOVERS INCREASE: Despite a decline in the average rollover amount in 2010, total assets being rolled over have been increasing. $4.2 billion was rolled over in 2010, up from $4 billion in 2009. The average rollover increased from $592 in 2006 to $1,295 in 2009, and fell to $1,029 in 2010. The percentage of individuals without a rollover decreased from 23 percent in 2006 to 10 percent in 2009 and increased slightly to 13 percent in 2010. HEALTHY BEHAVIOR MEANS HIGHER ACCOUNT BALANCES AND HIGHER ROLLOVERS: Individuals who exercised, those who did not smoke, and those who were not obese had higher account balances and higher rollovers than those with less healthy behaviors. It was also found that individuals who used cost or quality information had higher account balances and higher rollovers compared with those who did not use such information. However, no relationship was found between either account balance or rollover amounts and various cost-conscious behaviors such as checking pricing before getting services or asking for generic drugs instead of brand names, among other things. DIFFERENCES IN ACCOUNT BALANCES: Men have higher account balances than women, older individuals have higher account balances than younger ones, account balances increase with household income, and education has a significant impact on account balances independent of income and other variables. DIFFERENCES IN ROLLOVER AMOUNTS: Men rolled over more money than women, and older individuals had higher rollover amounts than younger individuals. Rollover amounts increase with household income and education, and individuals with single coverage rolled over a higher amount than those with family coverage.  相似文献

ASSET LEVELS GROWING: In 2011, there was $12.4 billion in health savings accounts (HSAs) and health reimbursement arrangements (HRAs), spread across 8.4 million accounts, according to data from the 2011 EBRI/MGA Consumer Engagement in Health Care Survey, sponsored by EBRI and Matthew Greenwald & Associates. This is up from 2006, when there were 1.3 million accounts with $873.4 million in assets, and 2010, when 5.4 million accounts held $7.3 billion in assets. AFTER LEVELING OFF, AVERAGE ACCOUNT BALANCES INCREASED: After average account balances leveled off in 2008 and 2009, and fell slightly in 2010, they increased in 2011. In 2006, account balances averaged $696. They increased to $1,320 in 2007, a 90 percent increase. Account balances averaged $1,356 in 2008 and $1,419 in 2009, 3 percent and 5 percent increases, respectively. In 2010, average account balances fell to $1,355, down 4.5 percent from the previous year. In 2011, average account balances increased to $1,470, a 9 percent increase from 2010. TOTAL AND AVERAGE ROLLOVERS INCREASE: After declining to $1,029 in 2010, average rollover amounts increased to $1,208 in 2011. Total assets being rolled over increased as well: $6.7 billion was rolled over in 2011, up from $3.7 billion in 2010. The percentage of individuals without a rollover remained at 13 percent in 2011. HEALTHY BEHAVIOR DOES NOT MEAN HIGHER ACCOUNT BALANCES AND HIGHER ROLLOVERS: Individuals who smoke have more money in their accounts than those who do not smoke. In contrast, obese individuals have less money in their account than the nonobese. There is very little difference in account balances by level of exercise. Very small differences were found in account balances and rollover amounts between individuals who used cost or quality information, compared with those who did not use such information. However, next to no relationship was found between either account balance or rollover amounts and various cost-conscious behaviors. When a difference was found, those exhibiting the cost-conscious behavior were found to have lower account balances and rollover amounts. DIFFERENCES IN ACCOUNT BALANCES: Men have higher account balances than women, older individuals have higher account balances than younger ones, account balances increase with household income, and education has a significant impact on account balances independent of income and other variables. DIFFERENCES IN ROLLOVER AMOUNTS: Men rolled over more money than women, and older individuals had higher rollover amounts than younger individuals. Rollover amounts increase with household income and education, and individuals with single coverage rolled over a slightly higher amount than those with family coverage.  相似文献

The researchers tabulated the academic affiliations of the authors of all articles published between 2004 and 2008 in 6 major social work journals to produce a ranking of the colleges and universities whose faculty made the most substantive contributions to the social work literature. The results of this analysis are compared with findings of 5 identical, previously published studies, which cover the 5-year periods of 1979-1983, 1984-1988, 1989-1993, 1994-1998, and 1999-2003. The limitations of this method of analysis are discussed, as are its merits.  相似文献

Physical activity (PA) is beneficial for cancer survivors across the cancer trajectory. Evidence indicates physical and psychosocial benefits, and ultimately, enhanced overall quality of life, for individuals who are more versus less active (Semin Oncol Nurs 23:285–296, 2007; Cancer Epidemiol Biomarkers Prev 14:1672–1680, 2005; J Cancer Surviv 4:87–100, 2010). A number of recent reviews have been conducted that examine different patient or survivor populations and outcomes. In general, the findings across the reviews reveal potential positive associations between exercise (structured activity one engages in for the purposes of enhancing health-related fitness outcomes) and PA (any physical movement, including lifestyle types of activity) with both physical and psychological outcomes. It is important to note, however, that depending on the nature of the review and the types of studies included in the review, the strength of the findings (i.e., effect size) vary. Despite this overwhelmingly positive evidence for the benefits of PA, activity levels are very low among cancer survivors, with one study reporting only 22 % of survivors as active enough to achieve health benefits (Cancer 112(11):2475–2482, 2008). This suggests that we must begin to better understand the factors that impact the uptake and maintenance of PA among cancer survivors. These potential factors are important when considering the patient-reported outcomes to assess and can include timing (i.e., during or after treatment completion), characteristics of the cancer diagnosis and subsequent treatments (i.e., early vs. late stage cancers), and characteristics of the individual (i.e., older vs. younger).  相似文献
