We investigate the relationship between providing school meals programmes and educational outcomes in Ethiopia. Using data from school catchment areas across rural Ethiopia, the paper examines the role played by programme modalities and their implementation. The results indicate that supplementing on-site school meals with take-home rations can be beneficial for concentration, reading, writing and arithmetic skills. The timing of the distribution of school meals is also found to play an important role. 相似文献

In the network of political and public administrative actors the public administration plays a key role. Countries previously influenced by socialism or communism, that joined the European Union in the two most recent accession waves, and are now undergoing strong change, are investigated to determine whether—and to what extent—public administrations influence transition processes to more democracy and market economies. With a regression analysis it is demonstrated that a qualitatively better functioning public administration makes a positive impact on transition, its effectiveness, and sustainability. The regression analysis also offers arguments for the view that public administrations are important actors when it comes to the implementation of EU standards. 相似文献

Political communication research has long been plagued by inaccurate self-reports of media exposure. Dilliplane, Goldman, and Mutz (2013) propose a new survey-based measure of “televised exposure to politics” that avoids some of the features that lead to self-report error and that has already been adopted by the American National Election Study. Yet the validity of the new measure has not been independently tested. An analysis reveals several weaknesses. First, construct validity of the new measure is low because it does not attempt to measure the amount of exposure to news programs, news channels, or news overall. Second, its convergent validity is poor by several different criteria. For example, the new measure shows barely any increase in news exposure as the 2008 presidential election approached. Third, the authors' criterion for predictive validity is neither necessary nor sufficient. Dilliplane, Goldman, and Mutz are right that measuring the media exposure of survey respondents in a valid and reliable way is critical for progress in political communication research. But given the inability of many respondents to report their own exposure, it is necessary to monitor the media use of survey respondents automatically. 相似文献

Proponents as well as critics of carbon trading underestimate the institutional and political underpinnings of evolving carbon markets. Based on institutionalist approaches, this paper argues that the strong embeddedness of carbon markets explains why certain characteristics (positive and negative) materialize. Focusing on the actors who initiate and who influence carbon markets, this article also shows that currently only states and intergovernmental agreements provide the necessary regulation for carbon markets to exist and to work. Today, neither market actors nor NGOs nor public private partnerships have the political power to set up, regulate or capture evolving market structures. Thus, whether or not market‐based instruments bring about the desired results depends on good public regulation, which is – at least up to now – represented by the state. Four instances of the commodification of carbon serve as illustrations: the European Union Emission Trading System (EU ETS); the Clean Development Mechanism (CDM); the voluntary market; and new sectoral approaches, particularly Reducing Emissions from Deforestation and Degradation (REDD+). 相似文献

Scientific conversations can be riddled with confusion when contributions to the discussion are based on notions about ways of knowing that remain implicit. Researchers often mix different methodological positions in their research designs because they lack an awareness of the distinctions between different ways of knowing and their associated methods. The authors engage and reflect on these differences, with particular attention to four areas: research question formulations, the character and role of concepts and theories, hypotheses versus puzzles, and case study research. They call on all researchers, both academics and practitioners, to be aware of the ways in which scientific terms serve, in research debates, as signifiers of different logics of inquiry. Awareness of these differences is important for the sake of productive scientific discussions and for the logical consistency of research, as both of the ways of knowing discussed here are legitimate scientific endeavors, albeit invoking different evaluative criteria. 相似文献

This article argues that the study of European integration is divided into two distinct approaches: classical integration theory for which the shape of the Euro‐polity is the dependent variable; and the governance approach for which it is the independent variable. An historical and conceptual overview of the approach focuses on the efficiency side of governance and excludes issues of democracy and legitimacy. From a sociology of knowledge perspective, the first part traces the roots of the present discussion back to three bodies of literature, namely studies on Europeanization, regulatory policy‐making and network concepts. The second part presents the achievements of the approach: putting EU studies in a comparative perspective, directing attention towards democratic governance and bypassing old dichotomies on the future of the nation‐state. The final section evaluates present shortcomings, most notably a bias toward problem‐solving, the proliferation of case studies and the lack of a coherent theoretical perspective. 相似文献

An approach toward detecting hidden knowledge is the Concealed Information Test (CIT). It relies on the memory of crime‐relevant information. This study investigated whether its validity is susceptible to memory distortion by misleading information. A misleading information paradigm was employed to distort memory prior to an interrogation with a CIT. Forty‐one participants watched a video with specific crime‐related information. After a 1‐week retention interval, misleading information was introduced. Afterward, a CIT was performed, followed by a threefold memory test. When misleading information was presented, memory performance was reduced, and no physiological response differences between crime‐relevant and crime‐irrelevant information were found. Without presenting misleading information, physiological responses differed between responses to crime‐relevant and crime‐irrelevant information. However, responses in all physiological measures also differed between misleading and irrelevant information. The results indicate that the CIT is susceptible to misleading information, which reduces its validity in specific constellations. 相似文献

Niche parties, which have been defined as focusing on a narrow range of issues their competitors neglect, are a phenomenon that has so far been described and analysed primarily in Western Europe. In this paper, we extend existing work by examining the presence and nature of niche parties in Latin America. Using the expert survey data collected by [Wiesehomeier, N., and K. Benoit. 2009. “President, Parties, and Policy Competition.” The Journal of Politics 71: 1435–1447], we show that there are niche parties in most Latin American party systems. Two kinds of niche party, traditionalist and postmaterialist, predominate. We also show that niche parties, despite being defined based on issue-based characteristics, are in fact less programmatic in their linkage strategies than mainstream competitors. Instead, niche parties are slightly more likely to draw on charismatic strategies and tend to establish strong organizational links to ethnic and religious organizations. Niche parties in Latin America are primarily vehicles for the mobilization of group interests. These findings have implications for our understanding of political representation in new democracies and niche party strategies more generally. 相似文献

Das Artenschutzrecht ist eine ausdifferenzierte, völker-, europa- und nationalrechtlich geprägte Rechtsmaterie. Ausgangspunkte einer Prüfung sind Schutzstatus der Art und die Handlung, die vorgenommen werden soll. Bei Eingriffen in besonders geschützte Arten durch Land-, Forst- oder Fischereiwirtschaft sowie durch zugelassene Eingriffe ist § 43 Abs. 4 BNatSchG eine Schlüsselnorm, die absichtliches Handeln voraussetzt. Absichtlich sind gezielte Beeinträchtigungen von Tieren und Pflanzen, nicht absichtlich sind Beeinträchtigungen, die sich als unausweichliche Konsequenz rechtmäßigen Handelns ergeben. An dieser Auslegung hat sich durch die Caretta-Entscheidung des EuGH nichts geändert. 相似文献
