Continued population growth and increasing urbanization have led to the formation of large informal urban settlements in many developing countries in recent decades. The high prevalence of poverty, overcrowding, and poor sanitation observed in these settlements—commonly referred to as “slums”—suggests that slum residence constitutes a major health risk for children. In this article, we use data from 191 Demographic and Health Surveys (DHS) across 73 developing countries to investigate this concern empirically. Our results indicate that children in slums have better health outcomes than children living in rural areas yet fare worse than children in better-off neighborhoods of the same urban settlements. A large fraction of the observed health differences appears to be explained by pronounced differences in maternal education, household wealth, and access to health services across residential areas. After we control for these characteristics, children growing up in the slums and better-off neighborhoods of towns show levels of morbidity and mortality that are not statistically different from those of children living in rural areas. Compared with rural children, children living in cities (irrespective of slum or formal residence) fare better with respect to mortality and stunting but not with respect to recent illness episodes. 相似文献

Family Dynamics Among Immigrants and Their Descendants in Europe: Current Research and Opportunities
This paper reviews recent research on family dynamics among immigrants and their descendants in Europe. While there is a large body of literature on various aspects of immigrant lives in Europe, research on family dynamics has emerged only in the last decade. Studies based on individual-level longitudinal data and disaggregated measures of partnership and fertility behaviour have significantly advanced our understanding of the factors shaping family patterns among immigrants and their descendants and have contributed to research on immigrant integration. By drawing on recent research, this paper proposes several ways of further developing research on ethnic minority families. We emphasise the need to study family changes among immigrants and their descendants over their life courses, investigate various modes of family behaviour and conduct more truly comparative research to deepen our understanding of how ethnic minorities structure their family lives in different institutional and policy settings. 相似文献

Research on community‐engaged learning tends to view this activity primarily, if not exclusively, from the vantage point of its benefits and challenges for students and educational institutions. Nevertheless, at least one other major actor is involved in this activity: the community. Neglect of the community perspective diminishes the overall value of student engagement. In this article we address this oversight by presenting new methodologies for valuing student engagement that take into account the community perspective. We argue that these approaches, which have their roots in the valuation of volunteer contributions to work organizations, can be extended fruitfully to the valuation of community‐engaged learning projects in institutions of higher learning. We recommend that application of these methodologies become an accepted part of the duties of university offices responsible for student engagement, and that researchers and practitioners continue to investigate more fully the value of engaged learning projects for the community. 相似文献

This paper bridges the leadership and organizational change literatures by exploring the relationship between managers' leadership competencies (namely, their effectiveness at person-oriented and task-oriented behaviors) and the likelihood that they will emphasize the different activities involved in planned organizational change implementation (namely, communicating the need for change, mobilizing others to support the change, and evaluating the change implementation). We examine this relationship using data from 89 clinical managers at the United Kingdom National Health Service who implemented change projects between 2003 and 2004. Our results lend overall support to the proposed theory. This finding suggests that treating planned organizational change as a generic phenomenon might mask important idiosyncrasies associated both with the different activities involved in the change implementation process and with the unique functions that leadership competencies might play in the execution of these activities. 相似文献

We characterize joint tails and tail dependence for a class of stochastic volatility processes. We derive the exact joint tail shape of multivariate stochastic volatility with innovations that have a regularly varying distribution tail. This is used to give four new characterizations of tail dependence. In three cases tail dependence is a non-trivial function of linear volatility memory parametrically represented by tail scales, while tail power indices do not provide any relevant dependence information. Although tail dependence is associated with linear volatility memory, tail dependence itself is nonlinear. In the fourth case a linear function of tail events and exceedances is linearly independent. Tail dependence falls in a class that implies the celebrated Hill (1975) tail index estimator is asymptotically normal, while linear independence of nonlinear tail arrays ensures the asymptotic variance is the same as the iid case. We illustrate the latter finding by simulation. 相似文献

Subjective Well-Being and Household Factors in South Africa 总被引:1,自引:2,他引:1
This paper uses a household surveyfrom South Africa to estimate a model ofsubjective well-being based upon poverty andhousehold characteristics including housing,sanitation, and transportation. Following Sen,we allow for factors in addition to income andwe begin to incorporate functionings andcapabilities as determinants of well-being. This study finds that important differencesexist among groups based upon their economicstatus. For the poorest quartilestransportation and housing play the mostimportant role in determining well-being, whilefor the richest quartiles, sanitation, water,energy, education and health are relativelymore important. These results have importantpublic policy implications because many of thefactors affecting well-being have large publicgood components. In addition, these resultscould be used to help governments focus aid inorder to improve well-being. 相似文献

Despite the large body of scholarship on drag and its performance of misogyny, mimicry, and masculinity, little attention has been paid to the role of musical genres in Black drag performance and its reception. This essay explores drag performances of gospel music and its relationship with the spectator at the Biology Bar, a Black gay drag site in Chicago. By examining the shift from the club "space" to the church "place," this research locates several possibilities for queer gospel performances. Through the introduction of a theory of transformance, this essay highlights the contradictions, complications, and complexities of the relationship between the Black church and the Black gay community. 相似文献

This study investigates age reporting on the death certificates of older white Americans. We link a sample of death certificates for native-born whites aged 85+ in 1985 to Social Security Administration records and to records of the U.S. censuses of 1900, 1910, and 1920. When ages in these sources are compared, inconsistencies are found to be minimal, even beyond age 95. Results show little distortion and no systematic biases in the reported age distribution of deaths. To explore the effect of age misreporting on old-age mortality, we estimate "corrected" age-specific death rates by the extinct-generation method for the U.S. white cohort born in 1885. With few exceptions, corrected and uncorrected rates in single years differ by less than 3% and are not systematically biased. When we compare corrected rates with those for the same birth cohort in France, Japan, and Sweden, we find that white American mortality at older ages is exceptionally low. 相似文献

The objective of this study is to evaluate an expanded version of the resource model of living arrangements among older persons.
This expanded model includes community-level measures of geriatric health services and housing market conditions. We employ
the first two waves of the National Survey of Families and Households to test static and longitudinal fixed effects models
of residential living arrangements. We find that residing in areas with higher levels of geriatric health care services increases
the likelihood of residential independence, net of other contextual factors and individual characteristics. Our results show
that housing market conditions are not related to levels of or changes in residential independence when control variables
are included in the models. The results for the individual-level resource variables show that persons with greater economic
resources, more children, and better functional status are better able to maintain independence and are less likely to die
or live in a nursing home. This study shows the utility of expanding on micro-level approaches to understanding community
living arrangements among older persons. Future investigations should include measures of the policy environment, transportation
constraints and opportunities, and a more complete array of indicators of health and social services oriented toward helping
elderly persons maintain their independence. 相似文献
