In 2010 the Danish regions started a new program of public health surveillance in collaboration with the national and local health authorities using the short form health survey (SF-12) for measuring and reporting on health related quality of life among the Danish adult population. The instrument has not, however, been validated in a Danish setting. The aim of this study was to assess the reliability and validity of the physical component summary (PCS) and the mental component summary (MCS) score of the 12-item short form health survey (SF-12) in a sample from Central Denmark Region. A total of 26,397 persons above the age of 25 were included in the analyses. Reliability was assessed by Cronbach’s α. The validity was assessed using known-groups comparisons and convergent validity. The factor structure was investigated through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The Cronbach’s α showed high reliability with a score of 0.90 and 0.85 for PCS and MCS respectively. The SF-12 discriminated well with respect to gender, age, educational status and long term illness. Individual items correlated higher with own hypothesized scales than with other scales and summary measures corroborating the convergent validity. The EFA gave a two-factor structure. Irrespective of the chosen rotation method (varimax and oblimin) the items related to PCS loaded on one factor and the items related to MCS loaded on another factor. The factor structure was validated with acceptable model-fit values in CFA. The SF-12 instrument is a reliable and valid measure of health related quality of life among the population of Central Denmark Region.  相似文献

The Valdez Principles is the latest of a series of voluntary codes of conduct that have been enunciated by various advocacy groups to guide the behavior of business enterprises. These principles provide guidelines on corporate conduct towards the environment and present a corporation with critical choices. This study suggests alternative strategies that firms may adopt to cope with this new code. Experience with the Sullivan and MacBride Principles is analyzed to serve as the basis to predict corporate response to the Valdez Principles.  相似文献

This article describes how a risk-return portfolio analysis, as originally developed in economics and finance, can be applied to product-line decisions. This approach uses direct estimates of return, and explicitly considers risk, or variation in return; most of the product portfolio models in use today forecast return by correlation, and lack explicit treatment of risk. The approach provides guidance for new product development activities as well as for allocating resources among a corporation's existing product lines. The article explains how organizations can apply this approach to their own product portfolio decisions, and includes a detailed example of how one company used this model.  相似文献

This paper argues that since the use of information is a fundamental part of all forms of activities, both corporate and private, throughout society the introduction of a new technology for using information inevitably has widespread effects. These effects are particularly far reaching in those service industries, such as banking, the very heart and essence of whose business is the handling of information.A review of the developments so far in the use of the new information technology in payment systems brings out the essential nature of its effects and shows the all-pervasive influence of the form and capability of the technology itself. It tries to illustrate where the benefits are derived and the nature of illusory gains and undesirable effects. An attempt is then made to derive an historical perspective.To try to anticipate future events, current trends in the technology and in the ways in which its use might change, are identified. The change in the technical means by which financial and other information-based services are delivered is seen to be salient feature of these developments and the important influence upon institutional relationships is discussed under the heading of the politics of the technology. Parallels in the introduction of other new technologies are drawn by way of illustration.The final part of the paper tries to develop a broader perspective and sketches out a longer scenario of the development of information technology indicating the major influence which this is likely to exert upon the development of society throughout the world.  相似文献

This article points to a fundamental inconsistency in the emerging market strategies of multinational firms. On the one hand, they seek billions of new consumers in the emerging markets of China, India, Indonesia, and Latin America—on the other, their marketing programs are scarcely adapted for these markets. The result is low market penetration, disappointing market shares and poor profitability. These multinationals are trapped by their own devices in gilded cages, serving the affluent few but ignoring the potential of the billions of new consumers that attracted them in the first place. In this article we propose that, in order to attract billions of new consumers, the marketing programs of multinationals need to be rethought from the ground up. We identify three key factors that characterize emerging markets: (1) low incomes, (2) variability in consumers and infrastructure, and (3) the relative cheapness of labor, which is often substituted for capital. We draw on numerous case studies from around the world to illustrate how to incorporate these realities into marketing programs. We conclude with a discussion of the implications of such an approach for the multinational’s core strategic assumptions.  相似文献

Suicide, the endpoint of a continuum that begins with suicide ideation, is the third leading cause of death among the US college-aged population. The first and second leading causes of death among this age group, unintentional injury and homicide, may also be linked to suicide ideation. We used data from the National College Health Risk Behavior Survey to examine the association between suicide ideation and injury-related behaviors among 18- to 24-year-old college students. Students who reported suicide ideation were significantly more likely than students who did not report considering suicide to carry a weapon, engage in a physical fight, boat or swim after drinking alcohol, ride with a driver who had been drinking alcohol, drive after drinking alcohol, and rarely or never used seat belts. Given this clustering of injury-related risk behaviors, college prevention programs should aim to reduce risks for injuries comprehensively, rather than addressing each risk behavior separately.  相似文献

Will paper recycling reduce the environmental impact of the European pulp and paper sector? If so, is maximal paper recycling the best policy to optimize the life cycle of the pulp and paper sector? We explore these questions using an approach that combines materials accounting methods and optimization techniques. Environmental impact data are inputs for a linear programming network flow model to find optimal configurations for the sector. These configurations consist of a mix of different pulping technologies, a geographical distribution of pulp and paper production, and a level of recycling consistent with the lowest environmental impacts. We use the model to analyse scenarios with different recycling strategies. Recycling offers a reduction in environmental impact in regions with a high population and a large production of paper and board products. Regions with a large production of graphic products should focus on cleaner virgin pulp production with energy recovery. We conclude that relocation of paper production also offers a reduction in environmental impact. However, the severe effects on the economy make this policy less attractive than a combination of recycling, cleaner pulp production and energy recovery.  相似文献

Modernity: a non-European conceptualization   总被引:1,自引:0,他引:1  
In the light of insights drawn from historical sociology and Parsons' theory of differentiation/modernization, an attempt is made to conceptualize modernity in such a way as to avoid both eurocentrism and the total rejection of the concept by those who view it as an ideological means for the further advancement of western cultural imperialism.  相似文献

This paper is a study of an emerging environmental decision-making model that attempts to move beyond traditionally adversarial approaches toward consensus building. Consensus-based decision making ostensibly allows activists equal power with industrialists and state actors in environmental policy-making. This research builds upon the growing literature on frame-analysis by demonstrating that there are instances when challengers actually engage in collaborative framing with their adversaries. This does not presume that activists reject oppositional framing altogether. In these cases, environmentalists actually draw on a mixture of confrontation and negotiation in this innovative form of collective action that positions them in contexts most environmentalists never experience—a place at the decision-making table with elites. This study reveals that environmentalists are becoming more sophisticated in their efforts to protect local communities and natural resources.  相似文献

Labour migration to the Gulf countries is predominantly contract based and a majority of workers fall below the salary ceiling necessary for sponsoring family members. Despite this, social networks have expanded in Kuwait, primarily in the form of sponsorship of additional labour migrants by those already in the country.
The objectives of the article are to describe how the process of arranging sponsorship works, to delineate the predictors of moving through a friend or relative, or arranging sponsorship for a subsequent labour migrant, and to assess the "multiplier" effect of the above process. The article is based on a survey among 800 South Asian skilled and unskilled male migrants, 200 each from Bangladesh, India, Pakistan and Sri Lanka.
About 34 per cent of all respondents moved through friends or relatives, 50 per cent through agents and 16 per cent through direct hiring or the government bureau. Logistic regression analysis indicated that the factors most likely to predict a move through the social network consisted of being a Pakistani or Indian, being a Muslim, and possessing some skills.
One-quarter of all migrants had arranged the visa for another migrant since they came to Kuwait. Logistic regression analysis showed the respondent's duration of stay in Kuwait to be an exceptionally important predictor for arranging sponsorship for an additional migrant.
Monthly income, being married and being a Muslim were also positively associated with arranging sponsorship. In terms of the multiplier effect, about 0.78 visas had been arranged per migrant. Pakistanis, who had the longest average duration of stay in Kuwait, arranged the maximum number (1.6) of visas on average.  相似文献
