This paper evaluates the short-run benefits of research and development (R&D) projects funded by the Automotive Lightweighting Materials (ALM) Program of the Office of FreedomCAR and Vehicle Technologies of the U.S. Department of Energy (DOE). The six ALM projects evaluated—using qualitative and quantitative evaluation methods—yielded numerous benefits in the short-run. From the qualitative assessment, all met their technical goals, increased intellectual knowledge among the research teams, and led to increased collaboration among DOE, the auto industry, its suppliers, and national laboratories. Moreover, U.S. competitiveness appeared to have increased as a result of each R&D effort. One interesting finding, however, is that most of the participants indicated their firms would not have engaged in the research efforts without DOE funding. If they had engaged in the effort, it would have been with considerably less person time and financial commitment. With respect to quantitative measures, several graduate students were supported by the projects and numerous publications and presentations resulted, although these metrics varied across the ALM R&D projects. 相似文献

Traditional methods of volatile detection used by police typically consist of reliance on canine olfaction. However, dogs have some limitations such as cost of training and time of conditioning. The possibility of using parasitic wasps for detecting explosives and narcotics has been developed. Moreover, wasps are cheap to produce and can be conditioned with impressive speed for a specific chemical detection task. We examined the ability of Nasonia vitripennis Walker to learn and respond to methyldisulfanylmethane (DMDS), a volatile discriminator of cadaver. The training aimed to form an association between an unconditioned stimulus (pupae) and the conditioned stimulus (odor source). After the training, the time spent by conditioned wasps in the DMDS chamber was measured. Statistical analysis showed that the increasing concentrations involved an increase in the time spent in the chamber containing DMDS. This study indicates that N. vitripennis can respond to DMDS, which provide further support for its development as a biological sensor. 相似文献

The Covid-19 pandemic has revealed and accelerated an information crisis as well as a health one. What we discover about Covid 19, how it spreads, to whom and why and how best to mitigate it—all depend on information. The essays in this special section, which this article introduces, explore the importance of information and the fundamental role of fact checkers in understanding how information flows, why mistakes are made, and how to counteract them. Fact checking as an idea and a practice emerged in the early twenty-first century, developed as a positive beacon to counteract a growing sense that information could no longer be trusted. Now, more than a decade after its creation, fact checking sits within a far more complex and chaotic media context, and its expertise and understanding has never been so important. We need to understand what fact checkers do because they are grappling with how to tether us to reality. 相似文献

AbstractThe main aim of this contribution is to assess the relevance of the notion of ‘exclusionary populism’ for the characterisation of the Front National (FN) in France. Since its emergence in the 1970s, several categories or notions have been applied to this political party. Once considered as the resurgence of a traditional extreme right, it has since been classified as a case of a new European right-wing extremism, or as one of the neo-populist parties that obtained electoral successes in the 1990s. The recent evolution of the party has also been described as a sort of ‘normalisation’. Is therefore ‘exclusionary populism’ still a category that can grasp the evolution of the party, as well as its present position in the French party system? To answer this question, this article examines political discourses and various electoral platforms of the Front National to gather some empirical evidence. The argument is twofold: The Front National, despite its ‘dédiabolisation’ strategy, is still a classic populist party characterised by exclusionary populism and a sort of ‘catch-all populism’; its evolution is, however, dependent on the recent evolution of the French party system. 相似文献

Both leadership and public value are increasingly seen as concepts highly relevant to public administration, not only because of complex societal challenges but also as ways to address pluralistic interests in society. This article explores in detail the varied conceptualizations of public value and of public leadership. Furthermore, we argue that political astuteness provides an important conceptual linkage between leadership and public value, enabling actors to read, understand and foster coalitions around diverse and sometimes competing interests. In this introduction to the symposium, we analyse the different conceptualizations of public value, of leadership, and also show how the six articles explicitly or implicitly draw on the linking concept of political astuteness. The article assesses how the six articles of the symposium contribute to each of these three concepts. 相似文献

Anti-immigrant parties in Europe: Ideological or protest vote? 总被引:1,自引:0,他引:1
Van Der Brug Wouter Fennema Meindert Tillie Jean 《European Journal of Political Research》2000,37(1):77-102
Abstract. In this article we address the question whether or not the votes for anti–immigrant parties can be considered as protest votes. We define protest votes by the motives underlying electoral choices, building on earlier research done by Tillie (1995) and Van der Eijk & Franklin (1996). That research showed that ideological proximity and party size are the best predictors of party preference. On this basis we designed a typology of motives for party choice and how these motives would manifest themselves empirically. Analyzing the 1994 elections for the European Parliament for seven political systems we show that anti–immigrant parties attract no more protest votes than other parties do, with only one exception: the Dutch Centrumdemocraten. Voting for anti–immigrant parties is largely motivated by ideological and pragmatic considerations, just like voting for other parties. In addition, (negative) attitudes towards immigrants have a stronger effect on preferences for anti–immigrant parties than on preference for other parties. Social cleavages and attitudes towards European unification are of minor importance as determinants of preferences for anti–immigrant parties. The overall conclusion is that a rational choice model of electoral behavior has strong explanatory power for party preferences in general, but also for the support for anti–immigrant parties in particular. 相似文献
