This article draws on a household survey of giving and volunteering undertaken as part of the Giving Australia project to explore the relationship between religion and the giving behaviour of adult Australians. We find that people who identify themselves as having a religion are more likely to give and to give more on average than people who do not but that this relationship is produced by a subset of this group; namely, people who regularly attend religious services. Indeed, the likelihood of giving and average amounts given by givers over a year increase with levels of attendance at religious services. The relationship holds even after allowing for other factors that affect the likelihood of a person giving and the amount given. It also holds for giving to nonreligious causes (ie when giving to religion is omitted). However, when we also omit giving to charities and look at giving to civic causes alone we find that the frequency of attendance at religious services has an ambiguous relationship with giving. A suggestion in overseas literature that it is participation in religious groups, rather than attendance at religious services that is associated with giving is not supported. 相似文献

This paper uses data from 2 randomized evaluations of welfare‐to‐work programs—the Minnesota Family Investment Program and the National Evaluation of Welfare‐to‐Work Strategies—to estimate the effect of employment on domestic abuse among low‐income single mothers. Unique to our analysis is the application of a 2‐stage least squares method, in which random assignment enables us to control for omitted characteristics that might otherwise confound the association between employment and domestic abuse. We find that increased maternal employment decreases subsequent reports of domestic abuse in both studies. In the Minnesota Family Investment Program—a program with an enhanced income disregard that allowed welfare mothers to keep a portion of their welfare income as earnings rose—an increase in household incomes appears to have contributed to reductions in reports of domestic abuse. 相似文献

Using concepts of neoinstitutional economics, such as transaction cost economics, institutional economics, property rights theory, and information economics, the development of the Open Source movement is investigated. Following the evolution of institutions in Open Source, it is discussed what the comparative institutional advantages of this model are. The conclusion is that it is the institutional framework of Open Source, not merely the low cost of Open Source software that makes it an attractive alternative mode of organizing the production and distribution of software and software-related services. Alternative organizations will be formed and existing organizations will be transformed to take advantage of its opportunities. 相似文献

The authors consider the problem of estimating the density g of independent and identically distributed variables XI, from a sample Z1,… Zn such that ZI = XI + σ? for i = 1,…, n, and E is noise independent of X, with σ? having a known distribution. They present a model selection procedure allowing one to construct an adaptive estimator of g and to find nonasymptotic risk bounds. The estimator achieves the minimax rate of convergence, in most cases where lower bounds are available. A simulation study gives an illustration of the good practical performance of the method. 相似文献

Estimation of the Pareto tail index from extreme order statistics is an important problem in many settings. The upper tail of the distribution, where data are sparse, is typically fitted with a model, such as the Pareto model, from which quantities such as probabilities associated with extreme events are deduced. The success of this procedure relies heavily not only on the choice of the estimator for the Pareto tail index but also on the procedure used to determine the number k of extreme order statistics that are used for the estimation. The authors develop a robust prediction error criterion for choosing k and estimating the Pareto index. A Monte Carlo study shows the good performance of the new estimator and the analysis of real data sets illustrates that a robust procedure for selection, and not just for estimation, is needed. 相似文献

This article describes the development of vegetable marketing in Ho Chi Minh City (Vietnam), where modern distribution outlets are competing fiercely with traditional traders for wholesale and retail customers. Data from interviews with supply chain stakeholders and a survey of vegetable wholesalers have been used to compare the performance of modern and traditional chains, and the findings reveal the chains as segmented in their product focus, the modern sector focusing exclusively on quality. Modern marketing channels are generally more efficient than traditional ones but still account for only around 2% of vegetable distribution. The article argues that policy‐makers should not promote the ‘modernisation’ of food systems at the expense of traditional channels which meet important consumer needs. 相似文献

Strategic partnerships have a key role to play in delivering the government's ‘Every Child Matters’ agenda. There is a developing body of research and other evidence and practice‐informed literature about what works in relation to partnership working. Drawing on a research review commissioned by Barnardos on strategic partnership working for children, this study summarises research findings from a number of sectors relating to the development, delivery and review of effective partnerships. Although there is widespread consensus within the research on the factors contributing to effective partnership processes, there is, currently, relatively little evidence that partnerships lead to positive outcomes for children and young people. © 2006 The Author(s).

This paper describes a project designed for college students unlikely to participate in international exchange programs but who, nonetheless, can learn much about intercultural communication through available resources in their own communities. The project involved a mentoring program between third and fourth year university students and first and second year ESL students at the same institution. The project was conducted over a 15‐week semester‐long course, and learning outcomes were documented through journal entries, written reflective statements, class discussions, oral presentations and instructor observations. A qualitative analysis of these data sources, framed through transformative learning theory, revealed outcomes leading to increased intercultural awareness. While engaging in face‐to‐face conversations, students transformed their prior knowledge about ‘others’ into a deeper understanding of themselves, their culture and their intercultural relationships. 相似文献
