A growing literature explores the degree to which firms learn from exporting. Although this literature finds that firms that export subsequently enjoy enhanced innovative performance, there has been little research that compares the effect of exporting to that of alternative internationalization activities. In this paper, we extend the literature to explore theoretically the differential effects of a firm’s exporting, foreign direct investment, and importing activity on its innovative outcomes. We test the resulting hypotheses using a sample of Spanish manufacturing firms from 2000 to 2008. We find that (1) learning associated with exporting is more pronounced than that associated with a firm’s FDI activities, (2) exporting and FDI operate as substitutes in their effect on a firm’s learning, and (3) although importing is positively associated with learning as manifested in new product introductions, it is not associated with learning as manifested in patenting activity. 相似文献

The aim of this article is to analyse the technical efficiency of the refuse collection services in 75 municipalities located in Catalonia, Spain. The analysis has been carried out using a great variety of techniques, both parametric and non‐parametric. Although the results naturally differ according to the technique used, they nevertheless are consistent in ranking the units analysed. Finally, we have looked into the relation existing between efficiency and the public or private management of the service. The results seem to support the idea that the framework for competition in which the service is provided could be more relevant than the private‐public management dichotomy. 相似文献

Abstract This article applies a historical institutionalist perspective to an empirical analysis of the sources and characteristics of the institutionalisation of European Union counter-terrorism. Drawing upon the work of Stone Sweet, Sandholtz and Fligstein, this paper critically analyses the impact of external crises in the form of major terrorist attacks on the emergence of counter-terrorism as an area of European governance. It also highlights the key policy and institutional developments, studies the role of policy innovators on the institutionalisation of counter-terrorism and supports the relevance of ‘transformative’ or ‘evolutionary’ models for the understanding of institutional change in this domain. 相似文献

AbstractThis paper explores the changing political economy of malaria drug discovery by tracing the career over the last four decades of a single molecule, tafenoquine. First identified as a promising antimalarial by the US Army in the 1970s, tafenoquine has recently been approved by the Food and Drug Administration for the radical cure of vivax malaria – the first product to receive marketing authorization for this indication in more than 65 years. The new drug is the result of a collaboration between the pharmaceutical company GlaxoSmithKline and the not-for-profit organization Medicines for Malaria Venture, with the financial support of the Bill and Melinda Gates Foundation. The successful development of tafenoquine, the paper argues, signals an important transition within the global health era: from the chemotherapeutic humanitarianism that characterized pharmaceutical efforts against malaria in the early 2000s, towards a period of drug discovery driven by the promise of global disease eradication. The paper uses the example of tafenoquine to advance a more general argument about the multiple and evolving pharmaceutical conjugations of malaria – the articulation of competing visions of the disease around the capabilities (and limitations) of particular molecules. 相似文献

In France, Germany, Spain, and the United Kingdom, the decades from the late 1980s to the present have witnessed significant change in health policy. Although this has included the spread of internal competition and growing autonomy for certain nonstate and parastate actors, it does not follow that the mechanism at work is a "neoliberal convergence." Rather, the translation into diverse national settings of quasi-market mechanisms is accompanied by a reassertion of regulatory authority and strengthening of statist, as opposed to corporatist, management of national insurance systems. Thus the use of quasi-market tools brings state-strengthening reform. The proximate and necessary cause of this dual transformation is found in the work of small, closely integrated groups of policy professionals, whom we label "programmatic actors." While their identity differs across cases, these actors are strikingly similar in functional role and motivation. Motivated by a desire to wield authority through the promotion of programmatic ideas, rather than by material or careerist interests, these elite groups act both as importers and translators of ideas and as architects of policy. The resulting elite-driven model of policy change integrates ideational and institutionalist elements to explain programmatically coherent change despite institutional resistance and partisan instability. 相似文献

Denture marking (DM) helps identify edentulous people with different methods. Analyzing perceptions and attitudes of denture wearers would enable understanding of the practical aspects, an analysis still absent in South America. Fifty‐three individual candidates for removable dentures were instructed on disaster victim identification (DVI) and the usefulness of DM for this purpose. They were physically shown eight DM systems and a questionnaire to which they responded by highlighting preferences in those systems. Although 98.11% did not know that dentures could be marked, only 9.43% denied interest in some type of DM. The 90.57% would mark their dentures with some system, preferring the inclusion of QR codes or a micro SIM card. The proven weaknesses of DVI and propensity for disaster mean this community in Chile is an opportunity to implement DM systems. Obstacles may come not from patients but from their dentists, educational institutions, or a lack of public policies. 相似文献

Computer-based production of comparison overlays from 3D-scanned dental casts for bite mark analysis
Martin-de las Heras S Valenzuela A Ogayar C Valverde AJ Torres JC 《Journal of forensic sciences》2005,50(1):127-133
Bite mark analysis assumes the uniqueness of the dentition can be accurately recorded on skin or an object. However, biting is a dynamic procedure involving three moving systems, the maxilla, the mandible, and the victim's reaction. Moreover, bite marks can be distorted by the anatomic location of the injury or the elasticity of the skin tissue. Therefore, the same dentition can produce bite marks that exhibit variations in appearance. The complexity of this source of evidence emphasizes the need for new 3D imaging technologies in bite mark analysis. This article presents a new software package, DentalPrint (2004, University of Granada, Department of Forensic Medicine and Forensic Odontology, Granada, Spain) that generates different comparison overlays from 3D dental cast images depending on the pressure of the bite or the distortion caused by victim-biter interaction. The procedure for generating comparison overlays is entirely automatic, thus avoiding observer bias. Moreover, the software presented here makes it impossible for third parties to manipulate or alter the 3D images, making DentalPrint suitable for bite mark analyses to be used in court proceedings. 相似文献
