As participatory governance approaches to local development get adopted also in transition countries, one of the key questions is how participation actually impacts local governance outcomes. This study examines the link between non-electoral participation and different public goods outcomes in rural Ukraine along with identifying the role of community-based organizations (CBOs). Using a unique survey data from Ukraine, I approach these questions empirically explicitly distinguishing between different public goods outcomes. I find that participation appears to be positively associated with local school and water supply outcomes. In addition, CBOs are found to be associated with better quality of water supply systems motivating a discussion about establishment of service cooperatives for water supply as a functional local governance arrangement. 相似文献

Most Pacific Island countries are located in the tropics, where there is an abundance of mosquitoes with the potential to
carry debilitating or life-threatening vector-borne diseases. This article examines three Melanesian countries in which malaria
is endemic—Papua New Guinea, Solomon Islands and Vanuatu—but the threat posed by the spread of malaria gives the issues a
broader significance to the Pacific region. After discussing the spatial distribution and prevalence of malaria in the Pacific,
the article examines a number of health interventions through which people have sought to control malaria. Although the disease
was nearly eradicated in the Pacific in the 1970s, it is no longer in retreat. The article concludes by examining why there
are still grounds for cautious optimism, and the challenges that Pacific Island countries face in reducing the impact of malaria
on their populations. There is a need for prompt and concerted action on malaria at the national, regional and international
levels if the public health concerns arising from the disease are to be adequately addressed. 相似文献

In this paper, we study the MDPDE (minimizing a density power divergence estimator), proposed by Basu et al. (Biometrika 85:549–559,
1998), for mixing distributions whose component densities are members of some known parametric family. As with the ordinary
MDPDE, we also consider a penalized version of the estimator, and show that they are consistent in the sense of weak convergence.
A simulation result is provided to illustrate the robustness. Finally, we apply the penalized method to analyzing the red
blood cell SLC data presented in Roeder (J Am Stat Assoc 89:487–495, 1994).

While it is well known that the widowed suffer increased mortality risks, the mechanism of this survival disadvantage is still
under investigation. In this article, we examine the quality of health care as a possible link between widowhood and mortality
using a unique data set of 475,313 elderly couples who were followed up for up to nine years. We address whether the transition
to widowhood affects the quality of care that individuals receive and explore the extent to which these changes mediate the
elevated mortality hazard for the widowed. We analyze six established measures of quality of health care in a fixed-effect
framework to account for unobserved heterogeneity. Caregiving and acute bereavement during the transition to widowhood appear
to distract individuals from taking care of their own health care needs in the short run. However, being widowed does not
have long-term detrimental effects on individuals’ ability to sustain contact with the formal medical system. Moreover, the
short-run disruption does not mediate the widowhood effect on mortality. Nevertheless, long after spousal death, men suffer
from a decline in the quality of informal care, coordination between formal and informal care, and the ability to advocate
and communicate in formal medical settings. These findings illustrate women’s centrality in the household production of health
and identify important points of intervention in optimizing men’s adjustment to widowhood. 相似文献

Standardization and decomposition are established and widely used demographic techniques for comparing rates and means between
groups with differences in composition. The difference in rates and means has heretofore been resolved in terms of the contribution
of variables to compositional effects for each variable and an overall rate effect. This study demonstrates that the resolution
of differences is attainable at the categorical level for both compositional effects and rate effects. Refinements to Das
Gupta’s equations yield a complete decomposition because of the additivity of categorical compositional and rate effects.
Other refinements allow the decomposition of polytomous variables. Extensions to the method provide for the decomposition
of the standard deviation and the multivariate index of dissimilarity. 相似文献

In this study, I examine disparities in schooling progress among children born to immigrant and U.S.-born blacks. I find that
in one- and two-parent families, children born to black immigrants are less likely to fall behind in school than those born
to U.S.-born blacks. In two-parent immigrant families, children born to two immigrant parents have a significant schooling
advantage over children born to one immigrant parent. While children born to two immigrant parents in the wealthiest black
immigrant families do better in the second generation than in the first, the reverse is observed among children in less wealthy
families. These findings contribute in two ways to our understanding of the assimilation processes of children born to black
immigrant parents. First, they show that there is a positive association between the number of immigrant parents in a family
and children’s schooling performance. Second, they suggest that disparities in the assimilation patterns of the children of
black immigrants are a likely product of the interaction between their parental characteristics and the socioeconomic circumstances
of their families. 相似文献

Obesity is considered a major cause of premature mortality and a potential threat to the longstanding secular decline in mortality
in the United States. We measure relative and attributable risks associated with obesity among middle-aged adults using data
from the Health and Retirement Study (1992–2004). Although class II/III obesity (BMI _ 35.0 kg/m2) increases mortality by
40% in females and 62% in males compared with normal BMI (BMI = 18.5-24.9), class I obesity (BMI = 30.0-34.9) and being overweight
(BMI = 25.0-29.9) are not associated with excess mortality. With respect to attributable mortality, class II/III obesity (BMI
_ 35.0) is responsible for approximately 4% of deaths among females and 3% of deaths among males. Obesity is often compared
with cigarette smoking as a major source of avoidable mortality. Smoking-attributable mortality is much larger in this cohort:
about 36% in females and 50% in males. Results are robust to confounding by preexisting diseases, multiple dimensions of socioeconomic
status (SES), smoking, and other correlates. These findings challenge the viewpoint that obesity will stem the long-term secular
decline in U.S. mortality. 相似文献

This analysis joins the debate on how declines in marriage have shifted the composition of the unmarried and married populations
in the United States, and how compositional shifts have affected nonmarital birth rates. Gray, Stockard, and Stone (2006)
presented one model for compositional effects that Ermisch (2009) challenged with alternative statistical tests. I propose
an alternative model for compositional shifts based not on theory but on observed marriage and fertility patterns. The results
from this alternative model are consistent with Ermisch’s findings yet support Gray et al.’s general case that compositional
effects have had an important infiuence on nonmarital birth rates. 相似文献

In this article, we analyze mortality rates of Finns born in areas that were ceded to the Soviet Union after World War II
and from which the entire population was evacuated. These internally displaced persons are observed during the period 1971-2004
and compared with people born in the same region but on the adjacent side of the new border. We find that in the 1970s and
1980s, the forced migrants had mortality rates that were on par with those of people in the comparison group. In the late
1980s, the mortality risk of internally displaced men increased by 20% in relation to the expected time trend. This deviation,
which manifests particularly in cardiovascular mortality, coincides with perestroika and the demise of the Soviet Union, which
were events that resulted in an intense debate in civil society about restitution of the ceded areas. Because state actors
were reluctant to engage, the debate declined after some few years, and after the mid-1990s, the death risk again approached
the long-term trend. Our findings indicate that when internally displaced persons must adjust to situations for which appropriate
coping behaviors are unknown, psychosocial stress might arise several decades after their evacuation. 相似文献
