This paper examines shareholder value drivers in European banking focusing on the efficiency and productivity features of individual banks. In particular, we analyse the value relevance of bank cost efficiency and total factor productivity (TFP) (in all its components, including technological change, pure technical efficiency change and scale efficiency change) to see how these influence shareholder value creation in European banking. The paper focuses on the French, German, Italian and U.K. banking systems over the period 1995–2002 and includes both listed and non-listed banks. We find that TFP changes best explain variations in shareholder value (measured by market-adjusted returns, MAR, for listed banks and by the ratio of EVAbkg to invested capital at time t−1 for non-listed banks). In both samples, we also find that technological change seems to be the most important component of TFP influencing shareholder value creation in European banking.  相似文献

Value‐added models (VAMS) are commonly used in high‐income countries for measuring the quality of teachers and schools, on the grounds that they are a fairer reflection of true quality than simple average test scores, as they account for differences in student intake. Not accounting for student's prior test scores can give a misleading impression of school quality. In this article, we adapt the current VAM of secondary school quality to the Ugandan context, and test its robustness. Using official test score data from Uganda, we test the robustness of the model to a range of different empirical specifications, including sensitivity to the inclusion of controls for student socioeconomic status. We find that the model is robust to a variety of different specifications and control variables. The VAM is low cost and has the potential to provide a clearer signal to parents, teachers, schools, and policy‐makers about how much learning is actually happening in different schools. This approach could be carried out at low cost in a wide range of low‐income countries that have similar testing regimes.  相似文献

This article examines the formation of a cross‐movement coalition between elements of the labor and environmental movements in New Jersey. We explain the successful formation and initial political campaign of the New Jersey Work Environment Council with an expansion of the theoretical perspective of frame analysis. We propose a model of a coalition collective action frame that offers several important insights into the active role coalition actors play in the construction of a common frame uniting union and environmental activists. Using qualitative data gathered from interviews, observations, and document analyses of two major campaigns, we argue that the coalition frame allowed new political opportunities to be created, leading to the establishment of the most sweeping right‐to‐know laws in the United States. We conclude the discussion of coalition framing by examining political constraints on the framing possibilities of coalitions, specifically by exploring how the discursive shift from the right to know to the right to act failed to expand the influence of the cross‐movement coalition as originally expected by its members.  相似文献

This paper considers the lives of children living in a large informal settlement in central Accra, Ghana. Its contention is that children remain largely absent from the renewal of interest in slums and that where they do feature it is largely as objects of risk and vulnerability. Such an exclusive focus, it is argued, risks effacing the ways in which children are capable of actively confronting the terrible constraints posed by slum environments and the ‘talent for living’ that this involves. Drawing upon the findings of a small qualitative exploratory research project, the paper examines sources of support and cooperation between children and how their decisions to work are perceived as a strategy to actively support mothers and families struggling for a subsistence.  相似文献

Foster children making the transition from birth to foster homes or from foster homes to foster homes often present problematic behaviors. Limitations of attachment theory and reactive attachment disorder are presented, and three alternative approaches for understanding behaviors exhibited in foster settings are presented: conservation of resources, child alienation model, and developmental trauma disorder.  相似文献

There is no single framework in place in the United Kingdom for collating and harmonizing the data on migration taking place between the subnational administrative units that constitute the home nations, together with the flows of international migration between these areas and the ‘rest of the world’. This paper proposes the construction of complete matrices of subnational migration statistics on an annual basis which can then be used to monitor migration trends throughout the UK in a comprehensive manner. The paper reviews how various ‘known’ flows are estimated by the national statistics agencies and develops estimates to fill in the gaps in the matrices. It then looks at changing patterns of migration in the UK between 2001/2002 and 2010/2011, showing that migration exhibits most activity in the middle of the decade. Flows within the home nations are the most consistent over time, while the patterns of international migration and migration across the borders of the home nations exhibit more substantial change. The latter flows, although relatively small in magnitude, have not previously been studied at the subnational level in any detail. Patterns of subnational internal and international net migration are found to be negatively correlated.  相似文献

Science on emerging environmental health threats involves numerous ethical concerns related to scientific uncertainty about conducting, interpreting, communicating, and acting upon research findings, but the connections between ethical decision making and scientific uncertainty are under‐studied in sociology. Under conditions of scientific uncertainty, researcher conduct is not fully prescribed by formal ethical codes of conduct, increasing the importance of ethical reflection by researchers, conflicts over research conduct, and reliance on informal ethical standards. This article draws on in‐depth interviews with scientists, regulators, activists, industry representatives, and fire safety experts to explore ethical considerations of moments of uncertainty using a case study of flame retardants, chemicals widely used in consumer products with potential negative health and environmental impacts. We focus on the uncertainty that arises in measuring people's exposure to these chemicals through testing of their personal environments or bodies. We identify four sources of ethical concerns relevant to scientific uncertainty: 1) choosing research questions or methods, 2) interpreting scientific results, 3) communicating results to multiple publics, and 4) applying results for policy making. This research offers lessons about professional conduct under conditions of uncertainty, ethical research practice, democratization of scientific knowledge, and science's impact on policy.  相似文献
