The Monterrey Consensus agreed at the UN summit on Financing for Development in 2002 promised a breakthrough in terms of donor generosity, aid effectiveness and new means of financing. However, the development orientation of world leaders proved to be short‐lived. This is even though our evaluation reveals progress since Monterrey in some areas, notably debt relief and private (FDI) flows. Calls for substantially scaling‐up regular aid had less effect than envisaged, and financial innovations have contributed only marginally to overall development financing so far. Nor is there much progress from the perspective of critics focusing on the quality of aid. In particular, the targeting of aid according to need and merit leaves much to be desired. The gap between words and deeds continues to be wide with regard to aid proliferation and donor co‐ordination as well. 相似文献

Attributes sampling is an important inspection tool in areas like product quality control, service quality control or auditing. The classical item quality scheme of attributes sampling distinguishes between conforming and nonconforming items, and measures lot quality by the lot fraction nonconforming. A more refined quality scheme rates item quality by the number of nonconformities occurring on the item, e.g., the number of defective components in a composite product or the number of erroneous entries in an accounting record, where lot quality is measured by the average number of nonconformities occurring on items in the lot. Statistical models of sampling for nonconformities rest on the idealizing assumption that the number of nonconformities on an item is unbounded. In most real cases, however, the number of nonconformities on an item has an upper bound, e.g., the number of product components or the number of entries in an accounting record. The present study develops two statistical models of sampling lots for nonconformities in the presence of an upper bound a for the number of nonconformities on each single item. For both models, the statistical properties of the sample statistics and the operating characteristics of single sampling plans are investigated. A broad numerical study compares single sampling plans with prescribed statistical properties under the bounded and unbounded quality schemes. In a large number of cases, the sample sizes for the realistic bounded models are smaller than the sample sizes for the idealizing unbounded model. 相似文献

We enter the 21st century contending with the end of the Cold War's legacy of political uncertainty, expecting youth to play a significant part in the search for new principles that will bring about stability in the world political order. In forging the future, youth will have to collaborate with adults, but on terms more fitting of the historical circumstances that lie ahead than those of the past. This was the framework adopted by a group of social scientists who held several discussions to reflect on the issues and opportunities that bear on youth's civic engagement and development in the century that has just opened. The present article describes the results of those conversations, starting with the issue of defining civic competence, and the finding that an expansive definition is needed to match the real‐world circumstances that affect its development for youth internationally. Specific conditions, such as globalization, information – communication technology, and immigration, are emphasized as forces that affect youth and need to be taken into account by educators and policy makers. In this regard, responsibilities of schools, government, the commercial sector, and community organizations are outlined. Each is viewed as a potential constructive force for promoting engagement insofar as youth's strengths are recognized and focus is placed on building on youth's proven capacities. As always, it is youth’s task to make history in the future and society's obligation to provide youth with sufficient resources and an honest basis for hope in carrying out this task. The authors' policy recommendations are founded on this reciprocal relation that binds the youth generation with its elders in the common task of preserving, while transforming, society for the good of humanity. 相似文献

Following current macro-level social change people are increasingly confronted with new demands encompassing perceived uncertainties concerning their job and career prospects. Studies utilizing concurrent assessments showed that perceiving a high accumulation (“load”) of such demands is negatively related to individuals’ subjective well-being. Without further evidence the interpretation of the direction of these effects, however, is equivocal. Based on the concept that individuals have a rather stable trait-like level of subjective well-being from which they may vary when confronted with changes of the external ecology, the current study examined the relationship between the reported load of demands and subjective well-being assessed as general life satisfaction and average satisfaction in domains of life (i.e., family, work, finances, and leisure). We expected that a higher load of demands corresponds to a temporary decline in well-being, while at the same time differences in the stable trait-like level of well-being account for differences in the reported demand load. For the purpose of our study, we analyzed three annual waves of assessment of German adults aged between 18 and 43 years (N = 488). Utilizing a trait-state-occasion model, we separated trait-like aspects of well-being from occasion-specific deviations. Overall, our results confirmed our expectation that effects indeed run in both directions. The higher the reported load of work-related demands, the more respondents’ well-being negatively deviated from the stable trait-like level. Beyond that a higher trait-like level of well-being corresponded to a lower demand load. Both effects revealed almost equal strength and remained stable after controlling for participants’ employment status, family status, and educational attainment. 相似文献

Social participation has been hypothesised to have both positive and negative impact on health outcomes via a variety of pathways, but previous studies have found few significant effects of social participation, and there is a lack of research from post-communist societies, which are known to be low on social capital. Using cross-sectional data from Poland on 2,970 individuals surveyed in 2009, we investigated the individual-level relationships between formal and informal social participation, emotional well-being, and risky alcohol consumption while controlling for demographic variables, socioeconomic status, employment and partnership status, health, religiosity, and generalised trust. Frequent joint activities with friends and neighbours were related to higher positive affect but also to more risky alcohol consumption. Membership in voluntary organisations was associated with more risky alcohol consumption, especially among younger males and for certain types of organisations. In contrast, volunteer work was related to higher positive affect and fewer depressive symptoms in the whole sample and to less risky alcohol consumption among the younger participants. The findings illustrate that some types of social participation, even if they are not typical of a given context (e.g., volunteering in Poland), may be more beneficial than others. 相似文献

The aim of this study is to estimate the causal effect of family size on the proximity between older mothers and adult children by using a large administrative data set from Sweden. Our main results show that adult children in Sweden are not constrained by sibship size in choosing where to live: for families with more than one child, sibship size does not affect child-mother proximity. For aging parents, however, having fewer children reduces the probability of having at least one child living nearby, which is likely to have consequences for the intensity of intergenerational contact and eldercare. 相似文献
