The aim of this study is to empirically analyze the performance of technology transfer offices (TTO) in Germany. Although being one of the largest and innovative economies in the world, there is only scarce evidence about the role and performance of TTO in university–industry technology transfer. While policy makers and university managers are often quite optimistic about the impact of TTO in fostering technology transfer into the region, consulting firms and research institutes report such institutions in Germany as superfluous and counterproductive. Using the number of invention disclosures as a performance measure, we analyze how variance in performance can be explained by different organizational structures and variables of TTO. Controlling for regional endowment and university specific effects, our results reveal that TTO performance is mainly a function of the kind of labor division within the TTO and the research intensity of the university. Knowing the drivers of TTO performance may help policy makers and university managers to reflect their strategies, mitigate weak points and thus foster performance.  相似文献

This research addressed how professionals involved with the legal system evaluate children, primarily between 4 and 8 years old, as witnesses. In particular, we focused on professionals’ beliefs and opinions regarding children's memory, suggestibility, and behaviors as they relate to witness credibility. In addition, we surveyed professionals’ evaluations of investigative methods related to reliability. Four hundred and seventy-eight professionals working with children in the Norwegian legal system (i.e. judges, police detectives, psychologists, child psychiatrists, prosecutors, and defense attorneys) completed a questionnaire about child witness issues. Results indicated that psychiatrists as well as police officers expressed greater belief in children's capacities than did other groups, whereas defense attorneys and psychologists were more skeptical regarding children's general credibility. Psychiatrists and psychologists both, however, tended to favor, more than did legal professionals, the use of clinical techniques with children in abuse investigations. Implications are discussed in relation to professionals’ attitudes toward children as witnesses.  相似文献

Abstract

Credibility judgments by police investigators were examined. Sixty-nine investigators viewed one of three video-recorded versions of a rape victim's statement where the role was played by a professional actress. The statements were given in a free recall manner with identical wording, but differing in the emotions displayed, termed congruent, neutral and incongruent emotional expressions. Results showed that emotions displayed by the rape victim affected police officers’ judgments of credibility. The victim was judged as most credible when crying and showing despair, and less credible when being neutral or expressing more positive emotions. This result indicates stereotypic beliefs about rape victim behavior among police officers, similar to those found for lay persons. Results are discussed in terms of professional expertise.  相似文献

Place marketing is increasingly being used as a governance strategy for managing perceptions about regions, cities, and towns. What are the most important obstacles to implementing place marketing? Based on a survey of 274 public managers involved in place marketing in the Netherlands, this article analyzes the main obstacles as perceived by public managers. It also analyzes the effects of obstacles on perceived results of place marketing in terms of attracting target groups. A factor analysis of a variety of obstacles investigated in the survey shows three clearly demarcated obstacles: administrative obstacles within municipalities, obstacles in developing the substance of marketing campaigns, and political obstacles. Obstacles in developing the substance of the marketing campaigns have significant effects on the results of place marketing in terms of attracting stakeholders, whereas the two other obstacles have no significant influence.  相似文献

Comparison of the minor and trace element compositions of bullet lead alloys has been used by some forensic examiners to make definitive positive associations between bullets or lead fragments at a crime scene and samples of bullets linked to a suspect(s). Such conclusions have been based on the elemental analysis of isolated groups of bullets with no consideration of the metallurgical processes involved in the production and refining of the bullet lead alloys. An understanding of the metallurgy of lead refining reveals that the elements quantified in the forensic analysis are carefully controlled in the refining process and that there are logical reasons why some elements are more discriminatory than others. Data for lead alloys supplied to two major ammunition manufacturers confirm that multiple indistinguishable shipments of lead alloys from secondary lead refiners to the ammunition manufacturers are made each year and over a period of many years. The data also demonstrate that distinguishable compositions can come from the same melt or "source" of lead alloy. These results clearly indicate that bullets with indistinguishable compositions could have come from different lead "sources" produced in the same or different years. Furthermore, the observation that two bullets have a distinguishable composition does not necessarily mean that they came from a different "source".Our results show that the forensic examiner using a method of bullet lead alloy elemental analysis, which quantifies up to six elements is restricted to concluding only that indistinguishable bullets might have come from the same "source," not that they did come from the same "source". In addition, it is quite possible that multiple bullets with similar but distinguishable compositions could have come from the same "source". The authors therefore feel that there is no scientific validity to any conclusions more positive than attributing the possible association as to molten source among bullets from different samples. An understanding of the metallurgical principles operative in the melting/casting process as well as the data acquired for this study, indicate that any forensic conclusions which associate unknown bullets with the "same source", and/or "same box" should fail most or all Daubert criteria.  相似文献

Mansfield's Missing Link: The Impact of Knowledge Spillovers on Firm Growth   总被引:1,自引:0,他引:1  
The purpose of this paper is to provide a link between two of the seminal contributions of Edwin Mansfield. The first focuses on the determinants of firm growth and the second is concerned with university-based knowledge spillovers. By linking both firm-specific characteristics as well as access to knowledge spillovers from universities, the empirical evidence found in this paper suggests that knowledge spillovers as well as firm-specific characteristics influence firm growth.  相似文献

The constitutionalization of the European Union represents a simultaneous and interacting process of polity building and constituency building. The EU’s social constituency is referred to as a particular constellation of public voice and resonance in the media in relation to European constitution making. This article compares constitutional claims-making in quality newspapers in France and Germany during the ratification period. It analyzes who raised their voices, what kinds of concerns and demands were put forward, which attitudes towards the EU were expressed and how particular visions of the EU were justified. A politicized and domestically focused French media sphere is contrasted with the German media that took the position of an attentive but passive observer of debates in other member states.  相似文献
