The purpose of this study is to examine the relationship between MCH service utilization and contraceptive use in five countries:
Bolivia, Guatemala, Indonesia, Morocco, and Tanzania. The analysis is carried out at the level of the individual woman, with
contraceptive-use status modeled as a function of: (1) the availability, quality, and packaging of MCH and family planning
services; (2) community- and individual-level determinants of health service and contraceptive use; and (3) intensity of prior
MCH service use. Data for the analysis comes from DHS data on women of reproductive age linked with data from service-availability
surveys. We use full-information, maximum-likelihood regression techniques to control for the effects of unobserved heterogeneity
that might otherwise bias our estimates. In three of the five countries (Morocco, Guatemala, and Indonesia) the results of
the analysis suggest that the intensity of MCH service use is positively associated with subsequent contraceptive use among
women, even after controlling for observed and unobserved individual- and community-level factors. This result lends support
to the proposition that, at least in the context of these three countries, the intensity of MCH service per se use does have a “causal” impact on subsequent contraceptive use, even after controlling for factors that “predispose” sample
women to use health care services. 相似文献

Though the general trend in the United States has been toward increasing life expectancy both at birth and at age 65, the temporal rate of change in life expectancy since 1900 has been variable and often restricted to specific population groups. There have been periods during which the age- and gender-specific risks of particular causes of death have either increased or decreased. These periods partly reflect the persistent effects of population health factors on specific birth cohorts. It is important to understand the ebbs and flows of cause-specific mortality rates because general life expectancy trends are the product of interactions of multiple dynamic period and cohort factors. Consequently, we first review factors potentially affecting cohort health back to 1880 and explore how that history might affect the current and future cohort mortality risks of major chronic diseases. We then examine how those factors affect the age-specific linkage of disability and mortality in three sets of birth cohorts assessed using the 1982, 1984, and 1989 National Long Term Care Surveys and Medicare mortality data collected from 1982 to 1991. We find large changes in both mortality and disability in those cohorts. providing insights into what changes might have occurred and into what future changes might be expected. 相似文献

The present study challenges the view that a new work ethic is widespread among the new generations of young people. A survey among 663 Flemish army recruits covering their attitudes to more traditional work motives and facets of the new work ethic, indicated that a “split” of the orientations to work according to educational level could be discerned. These results were interpreted as a social-psychological correlate of unemployment and discussed in the light of the ongoing social transformations of the so-called Third Industrial Revolution. 相似文献

In the growing debate about stakeholder values, there has been little discussion about information overload or whether the requested disclosures can be effectively used. Stakeholder advocates call for complicated and massive environmental and related social disclosures while not considering how information overload might affect the discourse about corporate performance. Stakeholders, including shareholders, plead for more transparency in financial statements, management discussion and analysis (MDA), and other corporate disclosures. As we know, shareholders and boards of directors are most concerned with the ‘Holy Trinity’ of earnings per share, dividends and market value changes. We believe that managers and stakeholders involved in performance evaluations have multiple interests that extend beyond traditional shareholder value measures. We note that the Balanced Scorecard (BSC) was developed as one tool to reflect and communicate these multiple measures. We test how managers use (or ignore) multiple performance measures and we posit that stakeholders will face many of the same constraints when using and processing multiple disclosures including Corporate Social Reports (CSR), environmental, or similar disclosures. While we do not directly test a wide variety of stakeholder disclosures, we examine eight (four for a single subject) shareholder values (financial measures) and four stakeholder values (nonfinancial measures). The eight measures included in our research instruments serve as proxies for the multiple concerns that might be of interest to many stakeholders. Note that stakeholders are likely to be extremely interested in nonfinancial performance measures, while many shareholders will likely concentrate on financial performance measures. Field research has reported managers tend to favor financial measures while discounting or ignoring nonfinancial measures when evaluating subordinates, making it difficult to align performance evaluations and incentives with corporate strategies (Ittner et al. Account Rev 78:725–758, 2003). In this study, we find the relative weights managers place on financial and nonfinancial performance measures are influenced by both (1) presentation order and (2) the relative importance of specific measures. When financial measures are presented first, the manager who performs better on financial measures is rated higher than the manager who performs better on nonfinancial measures. However, when nonfinancial measures are presented first, managers who excel on nonfinancial measures are rated higher. Reports that include financial measures that are relatively more (less) important also produce higher (lower) ratings for the manager who excels on financial measures. Thus, the relative weights that superiors place on financial and nonfinancial measures in evaluating corporate managers’ performance are substantially anchored both by the order in which measures are presented as well as by the importance of the specific performance measures employed. Other stakeholder disclosures are likely to be similarly anchored, perhaps biased, by primacy and a priori importance rankings. 相似文献

The aim of this article is to provide an overview of the current literature on the impact of the metabolic syndrome on male sexual health and current developments in the management of sexually dysfunctional men with a metabolic syndrome. The increasing prevalence across the world of the metabolic syndrome-a cluster of cardiovascular disease risk factors-causes the metabolic syndrome to be considered the most important threat to male sexual health of the 21st century. It has been shown to have a negative impact on male sexual function through its relationship with cardiovascular disease risk, its association with hypogonadism, and associated psychosocial factors. Besides established pharmacological and hormonal interventions, lifestyle modification programs are considered important therapeutic tools. 相似文献

Despite the scale, reach, and global impact of the human immunodeficiency virus (HIV), its study has remained largely at the purview of various micro-level analyses (e.g., Gutmann 2007; Levi and Vitória 2002). However, differences in prevalence rates at the national level suggest that other forces might be at work. Following the work of McIntosh and Thomas (2004), the only cross-national study of HIV/AIDS published to our knowledge, we conduct a cross-national analysis that examines world polity ideas that higher levels of health and women’s non-governmental organizations (NGOs) should be associated with lower levels of HIV prevalence. Initially, we find no support for these hypotheses. However, we respecify our models to test a political opportunity structure hypothesis that democracy enhances the ability of health and women’s NGOs to deal with HIV. We test this line of reasoning by including an interaction term between democracy and the health and women’s NGO variables. In doing so, we find that health and women’s NGOs are associated with lower levels of HIV prevalence in democratic rather than repressive nations. 相似文献

Value Stream Mapping (VSM) is a very popular tool in lean environments to represent production flows, mapping value stream of a product or family of products, and helps to identify some types of waste. Although very popular, this tool has some limitations as already described in many publications, especially in terms of restrictions in showing most types of waste as well as in its inability to represent various production routes. The purpose of this study is to introduce the waste identification diagram (WID), a new tool to represent production units with its different forms of waste, which overcomes some VSM limitations. The originality of WID comes from the use of its symbols’ dimensions to convey, in a visual and immediate way, relevant information about a production unit. In this paper, WID is applied on a production unit of a lift manufacturer, for testing its performance and comparing it to VSM. The main findings are that WID is in general more effective than VSM in terms of representation of complex production units and in terms of identification of more forms of waste. WID must however overcome some of its limitations such as the lack of information-flow representation and the links to suppliers and clients. 相似文献

This paper traces the use of the World Wide Web as a medium of political communication during the 1996 American presidential campaigns. Beginning with the Republican campaigns' use of the medium during the primary election season, a typology of uses of the web is outlined. While all campaigns felt it necessary to participate in the World Wide Web, different candidates used the medium differently. Furthermore, no campaign made full use of the much-publicized interactive capacity of the web; they used it more as a new means of transmitting traditional mass-media literature (video, graphics, etc.) and as a way of providing access to large volumes of campaign information (voting records, speeches, position papers, etc.). 相似文献

This paper disentangles the impact of schools and teachers in influencing achievement with special attention given to the potential problems of omitted or mismeasured variables and of student and school selection. Unique matched panel data from the UTD Texas Schools Project permit the identification of teacher quality based on student performance along with the impact of specific, measured components of teachers and schools. Semiparametric lower bound estimates of the variance in teacher quality based entirely on within‐school heterogeneity indicate that teachers have powerful effects on reading and mathematics achievement, though little of the variation in teacher quality is explained by observable characteristics such as education or experience. The results suggest that the effects of a costly ten student reduction in class size are smaller than the benefit of moving one standard deviation up the teacher quality distribution, highlighting the importance of teacher effectiveness in the determination of school quality. 相似文献
