Albania provides a small amount of social assistance to nearly20 percent of its population through a system that allows somecommunity discretion in determining distribution. This studyinvestigates how well this social assistance program is targetedto the poor. Relative to other safety net programs in low-incomecountries, social assistance in Albania is fairly well targeted.Nevertheless, the system is hampered by the absence of a clear,objective criterion to determine the size of the grants fromthe central government to communes as well as limited informationthat could be used to implement this criterion. Substantialgains in targeting could be achieved if the central governmentbetter allocated transfers to local governments, even holdinglocal targeting at base levels.  相似文献

Why hierarchies thrive   总被引:1,自引:0,他引:1  
Hardly anyone has a good word to say about hierarchies. Academics, consultants, and management gurus regularly forecast their imminent replacement because hierarchies--even when populated by considerate and intelligent people--can be cruel and stupid. They routinely transform motivated and loyal employees into disaffected Dilberts. It's no wonder that we continue to search for more humane and productive alternatives to them. Yet the intensity with which we struggle against hierarchies only serves to highlight their durability. Hierarchy, it seems, may be intrinsic not only to the natural world but also to our own natures. In this article, organizational behavior expert Harold J. Leavitt presents neither a defense of human hierarchies nor another attack on them. Instead, he offers a reality check, a reminder that hierarchy remains the basic structure of most, if not all, large, ongoing human organizations. That's because although they are often depicted as being out of date, hierarchies have proved to be extraordinarily adaptive. Over the past 50 years, for example, they have co-opted the three major managerial movements--human relations, analytic management, and communities of practice. Hierarchies also persist because they deliver real practical and psychological value, and they fulfill our deep need for order and security. Despite the good they may do, hierarchies are inevitably authoritarian. That authoritarianism shows up in all kinds of ways and influences everything in organizations, particularly communication. In multilevel organizations, for instance, messages get distorted as they travel up and down the ladder of command. Self-protection and self-interest weigh in, and relevant information is lost as messages make stops along the route. Sensitive leaders take steps to make speaking the truth as painless as possible. But it never is in organizations, because authoritarianism is an immutable element of hierarchy.  相似文献

National Parks are often major tourist attractions located in relatively remote and marginalised rural areas. The potential role of tourism in contributing to the costs of conservation and providing economic opportunities for communities living adjacent to natural heritage has long been recognised. Issues of access to tourists and capital, enclaves and bypasses and employment need to be addressed. The opportunities for local economic development through tourism at Komodo (Indonesia), Keoladeo (India), Gonarezhou (Zimbabwe) and Puerto Princesa (Palawan, Philippines) National Parks are explored, and the paper concludes with an agenda for action.  相似文献

The Citanduy II Project's model farm program on steep slopes in West Java was started in 1981 with the dual goals of reducing erosion and increasing farmer incomes. Limited success in reaching both goats has been achieved. Subsidies used to implement the program, however, could have been allocated more efficiently.  相似文献

This paper remedies ambiguity in the discussion of interdependent preferences by developing a consistent set of distinctions, which span the full range of sympathetic and antipathetic interaction, for the two-person case without reactive behavior. It defines concepts such as benevolence, generosity, altruism, destructiveness, and willingness to begrrudge transfers to others and indicates how their use can clarify the discussion of economic behavior. The definitions take account of preferences (indicated by rates of substitution) and prices (indicated by rates of exchange) at critical income allocations.  相似文献

The partial correlation is a commonly used measure for assessing the bivariate correlation of two quantitative variables after eliminating the influence of one or more other variables. The partial correlation is generally interpreted as the correlation that would result if the variables to be eliminated were fixed (not allowed to vary and influence the other variables), which is referred to in the statistical literature as conditional correlation. The present paper demonstrates, by means of theoretical derivations and practical examples, that when the assumption of multivariate normality is violated (e.g., as a result of nonlinear relationships among the variables investigated) the usual interpretation of the partial correlation coefficient will be basically incorrect. In extreme cases the value of the partial correlation coefficient may be strongly positive, close to 1, whereas the conditional correlation may have a large negative value. To solve this problem the paper suggests to partial out a certain function (in most cases the square) of the variables whose effects are to be eliminated if nonlinear relationships are likely to occur.  相似文献
