Guidelines from the American Heart Association (AHA) recommend that healthy adults limit their intake of dietary cholesterol to less than 300 mg per day. Since a large egg contains about 71% of that amount, the AHA recommends restricting egg consumption unless dietary cholesterol intakes from other sources are limited. We applied a risk apportionment approach to estimate the contribution of egg consumption and other modifiable lifestyle risk factors (e.g., smoking, poor diet, minimal exercise, and alcohol intake) to coronary heart disease (CHD) risk at the population level. Specifically, we categorized the U.S. adult population ages 25+ into distinct risk groups based on the prevalence of modifiable lifestyle risk factors and applied an apportionment model, typically used to assess risk contribution at the individual level, to estimate the contribution of egg intake to CHD risk. Our analysis shows that the combination of modifiable lifestyle risk factors accounts for less than 40% of the population CHD mortality. For the majority of U.S. adults age 25+, consuming one egg a day accounts for <1% of CHD risk. Hence, focusing on decreasing egg intake as an approach to modify CHD risk would be expected to yield minimal results relative to changing other behaviors such as smoking and other dietary habits. 相似文献

The purpose of this survey was to explore volunteer preferences, perceived benefits and barriers, and the factors that influence volunteering among older adults living in a continuing care retirement community. This was a single group, one-time survey completed via a face-to-face interview. The sample included 127 older adults who were eligible and completed the survey. The majority were women (78%) and White (98%), with an average age of 88.0 (SD = 6.5) years. Engagement in volunteer activities ranged from 0 to 7, with a mean of .94 (SD = 1.30). Just under half (47%) of the participants were engaged in volunteer work, with the majority (87%) volunteering within the facility. Perceived benefits and barriers to volunteering were described. Chronic illness, age, time spent exercising, and resilience accounted for 25% of the variance in volunteer activity. Those who had fewer chronic illnesses, were younger, spent more time exercising, and were more resilient were more likely to volunteer. Findings from this study suggest that there are advantages to offering volunteer activities within senior living facilities. Ongoing study is needed to develop and implement successful facility-specific volunteer programs. 相似文献

This study examined single mothers' concerns about the effects of father absence on boys. A two-pan questionnaire covering 11 dimensions of parent role and child development was administered to a group of single and a group of nonsingle mothers. Subjects rated the "importance" of a father and a mother and the effects of a father's absence on a boy. It was found that singles rated a father more important than nonsingles did, but singles also rated a mother more important-this was called the "parenting effect." All subjects rated a father as more important than a mother; the two most significant dimensions, especially for single mothers, were "sex role" and "play activity," substantiating previous research' and observation. The findings were discussed in terms of single mothers' psychosocial conditions, and clinical implications were offered. 相似文献

In the debate over parenting plans for infants and toddlers, a central question is whether these very young children should spend overnight time away from their mothers in their fathers’ care. This article summarizes and critiques the 11 empirical studies that have addressed this question. Overall, overnighting was not associated with negative outcomes for infants and toddlers and was associated with positive outcomes for preschoolers. 相似文献

Abstract While many studies of interventions have focused on their content and immediate effects, less research has focused on the processes that may explain these effects. The purpose of this study was to show how process evaluation can be used to interpret the results of an intervention study in four industrial canteens in Denmark. Two canteens acted as intervention groups and two as comparison groups. Effects were measured by surveys before and after interventions, and observations and interviews were conducted to provide an in-depth understanding of processes. Analyses were conducted based on the responses from 118 employees. Results showed, contrary to expectations, improvements in working conditions and well-being in one intervention group and in one comparison group, whereas no improvements were found in the two remaining groups. Data from the process evaluation enabled a meaningful interpretation of these results, raising the possibility programme failure rather than theory failure, and thereby constituting an example of how process evaluation can shed light over the factors that may influence outcomes in controlled intervention studies. 相似文献

Abstract Transformational leaders employ a visionary and creative style of leadership that inspires employees to make independent decisions and develop in their work. There is some evidence that the transformational (inspirational) leadership style is linked to employee burnout and stress. However, little research has focused on the psychological mechanisms that could explain this link, nor has there been a focus on positive affective well-being. We propose that transformational leaders influence their followers' self-efficacy, thereby affecting affective well-being in followers. This study extends previous work by examining the direct link between leadership and well-being both cross-sectionally (N=447) and longitudinally (N=188), and testing the mediating effects of self-efficacy. The study was carried out within parts of an elderly care department in a Danish local government. A theory-driven model of the relationships between leadership, self-efficacy and affective well-being was tested using Structural Equation Modelling. The results indicated that followers' self-ratings of self-efficacy mediated the relationship between transformational leadership style and positive affective well-being. Only limited evidence for a direct path between leadership behaviour and positive affective well-being was found. These findings have implications for how organizations may promote employee well-being, through interventions directed at supporting transformational leadership behaviours. 相似文献

This paper analyses the characteristics of good strategic performance that contribute to the overall performance of a successful company. We apply a framework of pragmatic constructivism in order to analyse and measure strategic performance. We use the model for performance measurement based on pragmatic constructivism for the more specific topics of measuring, assessing and analysing strategic performance as opposed to operational performance. This paper analyses the characteristics of strategic performance that successfully enhance the overall performance of the company. The purpose is to outline a framework for strategic performance measurement that can be used to guide and measure strategic leadership. The framework focuses on the concepts of coherence and coherence tracing as the basic concepts for strategic performance and thus the task for strategic performance measurement. 相似文献

This article critically examines transnational political engagement of migrants and refugees in local, national and global political processes. Based on inductive reading of existing scholarship and in particular the author's own research on Turks and Kurds in Europe, the article discusses key concepts and trends in our understanding of why, how and with what consequences migrants engage in transnational political practices. These practices, this article suggests, are influenced by the particular multilevel institutional environment, which migrant political actors negotiate their way through. This environment includes not only political institutions in the sending and receiving country, but also global norms and institutions and networks of other nonstate actors. Finally, the article argues for critical examination of the democratic transparency and accountability of migrants' transnational networks in any analysis of their long and short‐term impact on domestic and global politics. 相似文献

This paper presents the background, design and baseline results of the Intervention Project on Absence and Well-being (IPAW). IPAW is a 5-year psychosocial work environment intervention study including 22 intervention and 30 control work-sites from three different types of work-site (a large pharmaceutical company, municipal technical services, and municipal nursing homes) in Copenhagen, Denmark. The baseline survey reported in this paper was conducted in 1996-97, and the cohort was followed until 2002. Interventions took place during 1996-98 at the organizational and interpersonal level and focused on psychological demands, social support, control, meaning of work, and predictability. The main end-points are self-rated health, perceived stress, absence from work, job satisfaction, and labour turnover. Analyses of the baseline data show good reliability of the psychosocial scales and a number of clear associations between psychosocial work environment factors and health indicators. The baseline data also demonstrate several discrepancies between the planned design of the study and the actual implementation of the project in practice. 相似文献
