ABSTRACT

The usefulness of performance indicators increases when organizations compare their data. However, most discussions have failed to emphasize two lines of action that could improve the relevance of such comparisons: a) agreement among service managers on the indicators to be used in the evaluation; b) homogenization of the indicators to be used by organizations, and of the process used to calculate them. In this context, this paper proposes a methodology based on the participation of and consensus among managers, which helps to standardize the construction and presentation of performance indicators. The aim of this proposal is to improve the comparative evaluation of organizations. Finally, in order to test the proposal, a practical application is carried out on the local culture departments of nine large municipalities in southern Spain.  相似文献

The author quotes and briefly analyses a few exerpts taken from textbooks written and printed by Christain missionaries for the Congo primary schools. The Bible story of Cham cursed by his father, told in those texts from which Congolese children learned to read in the first half of the 20th century, stressed the white man’s superiority as coming from God.  相似文献

Technology Trade     
This study addresses the question of why some countries import more research and development-intensive goods than others. Using a panel data set of 80 countries for the period 1970–1995, results indicate that domestic investment, foreign direct investment and the quality of intellectual property rights systems positively affect technology imports. However, the higher the percentage of the workforce with primary studies, the lower technology imports are. Moreover, intellectual property rights tend to reinforce the positive role played by foreign direct investments in importing technology while the ability of imitation reduces the effect of intellectual property rights.  相似文献

The inefficiency of cooperative agriculture relative to private farms is often attributed to difficulties in monitoring or poor incentives. We develop a model to show that, in technologies with numerous sequential steps, even small shortfalls in worker effort can result in large output declines. Using data on cooperative and private farms in El Salvador, we find greater shortfalls in efficiency between cooperatives and private farms, as well as among cooperatives, for coffee, a crop requiring numerous steps in its cultivation, than for maize and sugar, which require fewer steps. Thus the undersupply of effort in cooperatives may be less than differences in productivity suggest, and cooperative agriculture is most likely to be successful where production does not involve many sequential steps.  相似文献

This study examines capital accumulation and growth among subcontracting small‐scale textile firms. We find that, in spite of the higher average profitability of non‐subcontracting production relative to subcontracting, the average annual rate of capacity expansion between the two groups is not statistically different from the former. This implies that the higher average productive capacity of the non‐subcontractors relative to that of the subcontracting firms are due to differences in their initial capacity. The study further suggests that there may be no easy transition from subcontracting to independent production. For many subcontractor firms in the sample, the cost of inputs required for independent production exceeds the current value of their gross earnings by a multiple.  相似文献

Much contemporary debate in forensic science concerns validity and admissibility of scientific evidence in court. In this paper, three current approaches to facial identification—image superimposition, photogrammetry, and morphological analysis—are considered with regard to criteria for scientific evidence in the United States, and England, and Wales. The aim of the paper is to assess the extent to which facial image comparison meets criteria of admissibility in these jurisdictions. The method used is a comparative evaluation of the methods of facial image comparison and their underlying premises against the range of admissibility criteria reported in court rulings and relevant judicial and scientific inquiries in the United States and the United Kingdom. While the techniques of facial image comparison are generally accepted within their practitioner communities, they are not tested, and their error rates are unknown. On that basis, the methods of facial image comparison would appear not to meet the anticipated standards. They are, nevertheless, admitted in court in the United States, and England, and Wales. This paper concludes that further research in science and law will be necessary to more definitively establish admissibility of facial image comparison evidence, as it will for other nascent and novel methods that are potentially influential in court proceedings.  相似文献
