Social researchers continue to grasp for critical factors that foster or impede the development of social capital. This article highlights some of these factors based on an investigation of a low‐income urban settlement in Guatemala. Community activists and leaders, elected representatives, regional government service providers, local residents, NGO directors and staff, and other key informants living and working within the designated locality indicated a complex and diverse range of social, cultural, political, and economic issues that contributed to low levels of ‘broad‐based’ social capital. Long‐standing fears related to violence and corruption within a historically top‐down authoritarian state were the most significant factors impeding social capital, social organising, and civic participation. Northern‐led service‐providing NGOs in the area also curbed ‘broad‐based’ social capital by fostering dependency through intervention strategies that were external, top down, non‐participatory, and not community based.  相似文献

The bulk and surface refractive indices have been measured for 20 float window glasses, 20 non-float window glasses, 20 patterned window glasses and 20 toughened float windscreen glasses.The refractive index of the tin-contact surface of the float glasses was always greater than that of the bulk, typically by 0.002 (range 0.00053–0.00307). In contrast the refractive indices of the two surfaces and the bulk of the sheet window glasses were in agreement within accepted experimental error in each case. A number of patterned window glasses showed significantly different refractive indices between the plain and patterned surfaces, the largest difference obtained (0.00021) being an order of magnitude smaller than that found for a typical float glass.Nine of the 40 float glasses examined yielded abnormal fragments from the upper surface in the sense that they did not disappear at the match temperature of the bulk glass. The refractive index measured from these abnormal fragments for two of these glasses was lower than the refractive index from the bulk glass.The variation in the bulk refractive index for the sheet and float window glasses produced an estimated standard deviation (E.S.D.) of 1.2 × 10?5. However, the patterned glasses were nearly three times as variable (E.S.D. = 3.3 × 10?5) and the toughened float glasses were, on average, almost seven times as variable (E.S.D. = 8.0 × 10?5).The value of making surface as well as bulk refractive index measurements in routine casework is discussed in the light of the above results.  相似文献

The work of state intermediate appellate courts is often described as “correcting legal errors” and “supervising” trial courts. But what do these labels mean in practice? This article explores the intermediate appellate process through a study of criminal appeals in a California Court of Appeal. Part I describes the characteristics and dispositions of criminal appeals. Contrary to popular impression, a conviction was reversed in only about 5 percent of these appeals. To explain the low reversal rate, part II draws upon interviews with justices of the Court of Appeal to examine the institutional norms and perspectives guiding the court's decisions. The basic decision norms described by the justices are norms of affirmance: for example, the harmless error rule and the substantial evidence rule incline the court to affirm despite certain legal errors or factual questions. Moreover, the particularistic approach the court typically takes in its decision making apparently sensitizes it to the substantive characteristics prevailing in criminal appeals: the crimes are serious and there is little doubt about factual guilt. The low reversal rate and the analysis of the court's norms suggest that intermediate appellate review of criminal convictions is narrower and more constrained than the “error correction” and “supervision” labels imply. Part III explores the implications of the case study for appellate policy.  相似文献
