Nongovernmental organization (NGO) networks have become key instruments used by NGOs in Latin America. Because these networks have important roles to play in advocating for the sector, earning public support, and improving the provision of public goods and services, understanding these networks is important to understanding the NGO sector more broadly. The article examines how NGO networks use collective texts to diffuse and adapt managerial practices. NGO networks use elements of managerialism and their adaptations to signal quality, secure recognition in social development, identify strengths and weaknesses of the sector, and define civil society in order to garner sector legitimacy. While looking at managerialism from a critical perspective, the article finds that understanding NGOs networks and the diffusion and adaption of NGO practices can further pinpoint effective sources of sector legitimacy and help to strengthen the sector’s role in social development. 相似文献

This article contributes to the growing amount of literature on co-production, focusing on co-production of public outcomes and taking the perspective of local government and public managers. A model for explaining the dynamics of outcomes’ creation at the community level is provided. The core argument of the article is that community outcomes result from a sum of peer production, co-production and inter-organizational collaboration processes promoted and activated at individual, organizational and network level across the public, third and private sectors. Institutional, managerial and organizational implications are discussed. The article argues that local government and public managers are asked to play new roles and to employ a new ethos grounded in a citizens capabilities’ approach. 相似文献

Ukraine has one of the world’s fastest growing HIV rates and was one of the largest recipients of funding from the Global Fund to Fight AIDS, Tuberculosis and Malaria (GF). Doctoral research recently completed by the author investigates the conduct and practice of international and national nongovernmental organisations (NGOs) as Principal Recipients of GF grants in Ukraine from 2004 to 2012. The study aimed to understand how NGO-based services were implemented in the context of a state-owned health care system. An ethnographic enquiry including 50 participant interviews was conducted in three oblasts in Ukraine, and in its capital, Kyiv, between 2011 and 2013. The paper is based on a doctoral research and presents some of the findings that emerged from the analysis. The author argues that the accent on NGO-run services promoted by GF has rendered the original grass roots, community-based NGOs, to be undermined or replaced by ‘quasi’, hybrid NGOs created by health officials and AIDS centres head doctors. The outcome of such hybridization is a weakened civil society that is dependent on external funding and is unable to genuinely represent their communities. 相似文献

Using RUMiC data and a simple panel quantile regression method, this paper accounts for the time-invariant individual specific characteristics and investigates the heterogeneous effects of factors on the distribution of subjective well-being (SWB, measured by GHQ-12) in urban China. Comparing results from the pooled regression and fixed effect regression, we find that most results from pooled regressions are likely overestimated. Panel quantile regression results show that income affects the least happy 10 % group twice as much as the happiest 10 % people. Being unemployed brings down the happiness level by 0.97 points on average, but individuals with high SWB seem to be not significantly affected. The complete picture of the relationship between SWB and various factors would have been veiled without using quantile techniques. This paper therefore not only contributes to the happiness literature in China, but also adds evidence to stylized findings going beyond the average. 相似文献

In this paper, we show that sequence pair (SP) representation, primarily applied to the rectangle packing problems appearing in the VLSI industry, can be a solution representation of precedence constrained scheduling. We present three interpretations of sequence pair, which differ in complexity of schedule evaluation and size of a corresponding solution space. For each interpretation we construct an incremental precedence constrained SP neighborhood evaluation algorithm, computing feasibility of each solution in the insert neighborhood in an amortized constant time per examined solution, and prove the connectivity property of the considered neighborhoods. To compare proposed interpretations of SP, we construct heuristic and metaheuristic algorithms for the multiprocessor job scheduling problem, and verify their efficiency in the numerical experiment. 相似文献

Jessie L. Breyer Andria M. Botzet Ken C. Winters Randy D. Stinchfield Gerald August George Realmuto 《Journal of gambling studies / co-sponsored by the National Council on Problem Gambling and Institute for the Study of Gambling and Commercial Gaming》2009,25(2):227-238
Young adulthood is a period renowned for engagement in impulsive and risky behaviors, including gambling. There are some indications
that young adults exhibit higher gambling rates in comparison to older adults. Problem gambling has also been linked to ADHD.
This longitudinal study examines the relationship between gambling and ADHD among an epidemiological sample of young adults
(n = 235; males = 179, females = 56) aged 18-24. Results indicate that individuals who report childhood ADHD symptoms which
persist into young adulthood experience greater gambling problem severity than participants with no ADHD or those with non-persistent
ADHD. 相似文献

In spite of the rising prevalence of marital dissolution in Asia over the past decades, little is known about single-parent families in Asia. The present study aims to contribute to the literature by investigating the changing socioeconomic characteristics and parental involvement (measured by parent–child activities and parental awareness of children) of single-father and single-mother families in Taiwan around the millennium. Using a nationally representative sample of 641 single fathers and 730 single mothers from the Taiwan Social Trend Survey collected in 1998, 2002 and 2006, this study found that the apparent socioeconomic advantage of single-father families over single-mother families has weakened. Parent–child activities and parental awareness are lower for single fathers than for single mothers and married fathers. The association between higher parental education and more parent–child activities and parental awareness is more pronounced among single fathers than among single mothers. The presence of co-residential grandparents is associated with lower parent–child activities with pre-teen children among single mothers. The results warrant greater attention to the wellbeing and development of adults and children from low SES single-father families in post-industrial Taiwan. 相似文献

There is a wide variety of stochastic ordering problems where K groups (typically ordered with respect to time) are observed along with a (continuous) response. The interest of the study
may be on finding the change-point group, i.e. the group where an inversion of trend of the variable under study is observed.
A change point is not merely a maximum (or a minimum) of the time-series function, but a further requirement is that the trend
of the time-series is monotonically increasing before that point, and monotonically decreasing afterwards. A suitable solution
can be provided within a conditional approach, i.e. by considering some suitable nonparametric combination of dependent tests
for simple stochastic ordering problems. The proposed procedure is very flexible and can be extended to trend and/or repeated
measure problems. Some comparisons through simulations and examples with the well known Mack & Wolfe test for umbrella alternative
and with Page’s test for trend problems with correlated data are investigated. 相似文献

Model-based clustering methods for continuous data are well established and commonly used in a wide range of applications. However, model-based clustering methods for categorical data are less standard. Latent class analysis is a commonly used method for model-based clustering of binary data and/or categorical data, but due to an assumed local independence structure there may not be a correspondence between the estimated latent classes and groups in the population of interest. The mixture of latent trait analyzers model extends latent class analysis by assuming a model for the categorical response variables that depends on both a categorical latent class and a continuous latent trait variable; the discrete latent class accommodates group structure and the continuous latent trait accommodates dependence within these groups. Fitting the mixture of latent trait analyzers model is potentially difficult because the likelihood function involves an integral that cannot be evaluated analytically. We develop a variational approach for fitting the mixture of latent trait models and this provides an efficient model fitting strategy. The mixture of latent trait analyzers model is demonstrated on the analysis of data from the National Long Term Care Survey (NLTCS) and voting in the U.S. Congress. The model is shown to yield intuitive clustering results and it gives a much better fit than either latent class analysis or latent trait analysis alone. 相似文献
