The U.S. electricity market, like electricity markets in most countries, is heavily dependent on fossil-fuel generation from centralized power applications. This paper reviews the factors that led to the sector??s reliance on fossil fuels and presents a future vision of the U.S. electricity sector based on a varied spectrum of sustainable energy resources ranging in scale from large, centralized facilities to small, localized energy systems. This spectrum includes low-emissions energy and energy efficiency, as well as macro-generation, micro-grids, distributed generation, micro-generation and end-user conservation. We discuss the evidence that each element of this spectrum is a viable and proven technology, the balanced integration of which could shape an electricity sector that adheres to sustainability principles. This paper concludes with a discussion of the institutional barriers that need to be addressed to successfully achieve a transition toward a more future sustainable electricity sector based on the variations in scale. 相似文献

Political alternate positions (otherwise known as substitutes) can have important effects on women's abilities to enter politics. Using the case of Nicaragua, this study assesses whether these alternate positions are being used to increase women's political representation or as a tool to undermine women's advancement into positions of power. By examining patterns of women's representation as candidates in the 1996, 2001, and 2006 elections for the National Assembly and as elected officeholders (as both alternates for those assembly members and titleholders), the article analyzes how various political parties are utilizing these alternate positions. Contrary to the conventional wisdom, this study finds no evidence that these alternate positions are used to undermine women's political progress. 相似文献

Résumé: La judiciarisation de l’action publique demeure un champ de recherche peu exploré par les politologues suisses. Cette note de recherche étudie dès lors l’évolution des 79’752 affaires liquidées par le Tribunal fédéral, de 1990 à 2010, en matière administrative. Les résultats empiriques montrent que le contentieux administratif croît de 45% sur la période observée, principalement en matière d’assurances sociales. Nous observons toutefois des différences notables entre les domaines de politiques publiques et quant à la provenance cantonale des recours devant le Tribunal fédéral. Ces différences s’expliquent par l’influence conjointe de facteurs conjoncturels (par ex. la croissance économique), institutionnels (par ex. l’organisation judiciaire cantonale) et liés aux acteurs du système judiciaire (par ex. la densité d’avocats). En conclusion de cette analyse exploratoire, cinq pistes de recherche sont identifiées afin d’étudier plus finement l’ampleur du processus de judiciarisation et d’en évaluer les impacts sur les politiques publiques. 相似文献

The authors report the results of a forensic medical investigation of 6 cases of death associated with the administration of pharmaceutical products documented by forensic medical experts of the Russian Centre of Forensic Medical Expertise. The results of the study are compared with the clinical data and summarized using the methods of tanatogenetic analysis. The following main clinical variants of iatrogenic anaphylactic shock (IAS) are distinguished: bronchospastic IAS (n = 1), asphyxic IAS (n = 1), hemodynamic IAS (n = 3), and combined (bronchospastic plus hemodynamic) IAS (n = 1). The signs of all these variants are described allowing for their diagnostics and differentiation diagnostics. These data can be used for the purpose of forensic medical diagnostics and elucidation of the mechanisms of tanatogenesis. 相似文献

The quantitative criteria for biometric ranging of destroyed corpses in terms of anatomical localization, gender, longitudinal length, trunk circumference, and the folds of subcutaneous fat are proposed. The wealth of anthropometric materials obtained in the studies of various Caucasoid populations was used to calculate the normative tables for biometric ranging of the decomposed corpses. The proposed technology excludes the subjective assessments for the purpose of such classification at the sites of catastrophes. Moreover, it promotes the accumulation of the variety of valuable information, such as the size of the collar, headwear, and footwear, clothing size and height, and portrait features, that can be used for victim identification. 相似文献

Determination of sex from fragmentary crania is a critical problem in forensic anthropology. Osteometric analysis of mastoid can serve forensic anthropologists better in sex identification by virtue of the noticeable dimorphic characteristics. The present study aims to develop population-specific, sex-differentiating anthropometric standards for the mastoid process of North Indian skulls. Eight parameters of the mastoid region were measured on 138 adult crania (M/F 104:34, 22-65 years) and analyzed using SPSS 16.0. All parameters showed significant sexual dimorphism (p < 0.000). In stepwise analysis, asterion-mastoidale and mastoid breadth have provided an accuracy of 87%. Receiver operating characteristic curves were obtained for each variable to observe their overall performance in sex determination. Posterior end of incisura mastoidea-depression of suprameatal triangle was found to be the best variable with maximum area under curve and highest predictive accuracy (82.6%). 相似文献

Situating events and traces in time is an essential problem in investigations. To date, among the typical questions issued in forensic science, time has generally been unexplored. The reason for this can be traced to the complexity of the overall problem, addressed by several scientists in very limited projects usually stimulated by a specific case. Considering that such issues are recurrent and transcending the treatment of each trace separately, the formalisation of a framework to address dating issues in criminal investigation is undeniably needed. Through an iterative process consisting of extracting recurrent aspects discovered from the study of problems encountered by practitioners and reported in the literature, common mechanisms were extracted and provide understanding of underlying factors encountered in forensic practise. Three complementary approaches are thus highlighted and described to formalise a preliminary framework that can be applied for the dating of traces, objects, persons and indirectly events. 相似文献

In this paper, we (1) examine the interactions of financial variables and the macroeconomy within the block-restriction vector autoregression model and (2) evaluate to what extent the financial variables improve the forecasts of GDP growth and inflation. For this reason, various financial variables are examined, including those unexplored in previous literature, such as the share of liquid assets in the banking industry and the loan loss provision rate. Our results suggest that financial variables have a systematic and statistically significant effect on macroeconomic fluctuations. In terms of forecast evaluation, financial variables in general seem to improve the forecast of macroeconomic variables, but the predictive performance of individual financial variables varies over time, even though it strengthens during the 2008?C2009 crisis. The results give some support for the risk-taking channel of monetary policy, as the level of the monetary policy rate is positively associated with the loan loss provision rate of commercial banks. Finally, a more stable financial system is found to contribute to faster economic growth. 相似文献
