Health care professionals most often approach health promotion for large persons in the context that health improvement can be attained only through weight loss. Unequivocal acceptance of the notion that thinness equals health and fitness has been the only health intervention strategy available for many large men and women. The apparent ineffectiveness of traditional diet and exercise programming to reduce body weight has caused many health care providers, obesity researchers, and lay persons to challenge the further use of diet and exercise for the sole purpose of reducing body weight in the large person. A brief survey of the most popular dieting techniques used over the past 40 years shows that most techniques cycle in and out of popularity, and that many of these techniques are hazardous to health. Data from the scientific community indicate that diet and exercise programs for weight loss are ineffective in producing reduced weight maintenance after a period of 3 to 5 years. On the other hand, there are data indicating that overweight men and women can become healthy without losing significant amounts of weight. Furthermore, epidemiological studies indicate that fitness, not fatness, is related to disease and mortality. Any intervention strategy for the obese should be one that promotes the development of a healthy lifestyle. The outcome parameters used to evaluate the success of such an intervention should be specific to disease risk and symptomatologies and not limited to medically ambiguous variables like body weight or body composition.  相似文献

Colin Sumner has declared that the sociology of deviance as a research specialty was “dead? by 1975; later influential studies on norm-violating behavior appeared only in the specific area of criminology. We subjected this argument to empirical test through an analysis of the most-cited scholars and works in 263 textbooks, articles, and research notes appearing in the sociology of deviance from 1993 to 1999. We found some support for Sumner's claims: The majority of the most-cited scholars in devi-ance today conduct research in other areas, primarily in criminology. Furthermore, among the 31 most-cited works in our analysis, only two of 15 studies classified in the sociology of deviance appeared after 1975. We conclude with some thoughts about the factors that contribute to the rise and fall of research specializations in sociology.  相似文献

Personality and organizational health: the role of conscientiousness   总被引:1,自引:0,他引:1  
Organizational health research identifies processes through which the work environment and individual differences combine to influence both individual and organizational outcomes. This study investigated the contribution of conscientiousness to organizational health. Research in the areas of occupational stress, work performance, and organizational climate was used to develop a framework for integrating different elements of organizational health. Within this framework, the work environment was assessed by perceptions of workload and role clarity ; individual well-being was assessed by psychological distress and job satisfaction ; and behaviour important for organizational success was assessed by contextual performance. Conscientiousness was investigated within the framework using self-reports from a sample of 104 Australian employees. Conscientiousness directly influenced contextual performance but did not influence well-being or perceptions of the work environment. Conscientiousness also reduced the impact of role clarity on both psychological distress and job satisfaction. The role of conscientiousness in a comprehensive model of organizational health is discussed.  相似文献

In the interest of developing a more holistic and integrated understanding of young children's experience of stories, this study describes preschoolers' emotional attachments to stories and the cultural beliefs and practices which surround such attachments. Thirty-two European-American, middle-class families, participated in an interview study of their children's story attachments, and five of these mothers also participated in a short-term, longitudinal diary study. Every child experienced at least two emotional attachments to stories. Children were captivated by stories presented in different media, with many attachments occurring around video stories in addition to books. They expressed their attachments by repeatedly requesting the story, expressing strong feelings, and enacting the story in pretend play. Story attachments were social in two fundamental ways: children created relationships with the characters in their favorite stories, and story attachments emerged in the context of relationships with caregivers whose beliefs and practices supported such attachments.  相似文献

This article presents the results of a simulation study investigating the performance of an approach developed by Miller and Landis (1991) for the analysis of clustered categorical responses. Evaluation of this “two-step” approach, which utilizes the method of moments to estimate the extra-variation pardmeters and subsequently incorporates these parameters into estimating equations for modelling the marginal expectations, is carried out in an experimental setting involving a comparison between two groups of observations. We assume that data for both groups are collected from each cluster and responses are measured on a three-point ordinal scale. The performance of the estimators used in both “steps” of the analysisis investigated and comparisons are made to an alternative analysismethod that ignores the clustering. The results indicate that in the chosen setting the test for a difference between groups generally operatbs at the nominal α=0.05 for 10 or more clusters and hasincreasing power with both an increasing number of clusters and an inrreasing treatment effect. These results provide a striking contrasc to those obtained from an improper analysis that ignores clustering.  相似文献

The effects of motherhood timing on career path   总被引:2,自引:1,他引:1  
This paper estimates the effects of motherhood timing on female career path, using biological fertility shocks to instrument for age at first birth. Motherhood delay leads to a substantial increase in earnings of 9% per year of delay, an increase in wages of 3%, and an increase in work hours of 6%. Supporting a human capital story, the advantage is largest for college-educated women and those in professional and managerial occupations. Panel estimation reveals both fixed wage penalties and lower returns to experience for mothers, suggesting that a “mommy track” is the source of the timing effect.  相似文献

How do we know things? The question of epistemology – which drives both the sociology and philosophy of science – is also a crucial question for political sociology. Knowledge is essential to even the most basic and foundational of political processes and institutions. In 2000, for example, the transition of power in the US presidential election hung for 36 days on uncertainty over a seemingly simple question of fact: who won the most votes in Florida? A few years later, disputed factual claims about Iraq's possession of weapons of mass destruction unraveled, calling into question key justifications of the US decision to invade Iraq in 2003 and significantly weakening perceived US legitimacy. Yet, surprisingly, sociologists and political scientists know relatively little about how knowledge gets made in political communities, nor how the making of knowledge is tied to other key aspects of political life, such as identity, authority, legitimacy, and accountability.  相似文献

The overwhelming obstacles to effective CPS intervention created by increasing reports of abuse and neglect, funding shortfalls, and the lack of qualified workers have prompted national efforts to reform the public child welfare system in the United States. Organizations such as the American Public Welfare Association, the Children's Defense Fund, the Child Welfare League of America, and the National Association of Social Workers are currently working closely with other national organizations to develop legislative proposals that will enable child welfare agencies to be more responsive to the needs of children and families. A critical component of this reform is the need to recruit, train, and retain qualified and competent CPS workers. The four training programs described in this article are examples of innovative programs seeking to enhance service delivery by enhancing the knowledge and skills of their staff members. Although the four programs were developed in very different political and social climates and within diverse organizational structures, they all provide useful lessons in how to develop efficient and effective training for workers delivering protective services for children. Any national, state, or local efforts to design and develop new CPS training programs should take into account the significant strides made by these agencies.  相似文献
