针对目前起重机安全评价过于依赖主观权重且忽视起重机安全状态变化趋势的问题，建立基于改进博弈论组合赋权法（improved combination weighting method of game theory，ICWGT）和灰色关联分析法的起重机安全评价体系。在该评价体系中，收集样本数据以确定评价值，构建评价等级空间来计算起重机行为特征序列与标准行为特征序列的关联系数。运用ICWGT在层次分析法和信息熵 未确知测度理论确定的主、客观权重中寻找平衡。充分考虑专家经验和样本数据，确定优化权重以改善关联系数的分配问题，从而获取起重机灰色关联度评价值和安全等级，旨在对起重机安全状态变化趋势进行更加准确的定量描述和定性分析。实例分析验证了该评价体系的有效性。  相似文献   

Projectification of Doctoral Training? How Research Fields Respond to a New Funding Regime     

Marc Torka 《Minerva》2018,56(1):59-83

Funding is an important mechanism for exercising influence over ever more parts of academic systems. In order to do so, funding agencies attempt to export their functional and normative prerequisites for financing to new fields. One essential requirement for fundees is then to construct research processes in the form of a project beforehand, one that is limited in time, scope and content. This article demonstrates how the public funding of doctoral programs expands this model of project research from experienced academics to the socialization process for the new academic generation. This process of “projectification” underlies funding-driven institutional changes in doctoral training. A multi-level comparative study of German policies, funding mechanisms and organizational frameworks for doctoral training demonstrates the emergence of a specific model of predefined PhD projects. The investigation of doctoral training practices reveals that socio-epistemic preconditions regulate whether research fields adopted or rejected this demanding model. This result contradicts widespread claims about a radical change in doctoral training and suggests focusing on the actual practices of field-specific doctoral research.  相似文献   

Ownership,organization structure and public service provision: the case of museums     

Enrico E. Bertacchini  Chiara Dalle Nogare  Raffaele Scuderi 《Journal of Cultural Economics》2018,42(4):619-643

This article provides an empirical investigation of the effects of the ownership and organizational structure on the performance of cultural institutions. More specifically, we consider how museums are effective in their function of disseminating culture to audiences and contributing to the local development. By exploiting a unique data set based on the 2011 census of Italian museums, we develop performance indices of accessibility, visitors’ experience, web visibility and promotion of the local cultural context. Using count data models, we regress such measures on the type of organization. We distinguish between governmental museums, public museums whose administration is either outsourced or has financial autonomy and private museums. We control for the most salient characteristics of a museum, competition pressure and some proxies of potential audience. Our evidence shows that private museums, public museums with financial autonomy and outsourced museums outperform public museums run as sub-units of culture departments. This paper contributes to the cultural economics and public policy and administration literature by adding insights into the effect of outsourcing and administrative decentralization in the public cultural sector.  相似文献   

Effects of the “Gangnam Style Syndrome” on the South Korean stock market     

Hyun Joung Jin  Jang-Chul Kim 《Journal of Cultural Economics》2018,42(1):139-161

This study attempts to answer two questions. First, can a single cultural event impact the stock prices of a wide range of companies and sectors? Second, was the positive stock market response in the information technology (IT) sector as well as performing arts sector significant? To answer these questions, we examine whether a hit pop single, “Gangnam Style” by Park Jae-Sang in 2012, affected related sectors of the Korean stock market and whether market reactions went beyond the stock price of the singer’s agency to affect those of other firms. We use an event study approach. The results show two notable empirical findings. First, although the findings indicating abnormal returns and cumulative abnormal returns appear mixed, the overall results imply that the unprecedented worldwide hit single by the South Korean singer positively affected the Recreation & Culture and Digital Content sectors. In other words, the market interpreted the event as good news, with shareholders expecting positive effects on the related sectors. Second, a positive stock market response was observed in the IT sector as well.  相似文献   

Idea generation in biomedical engineering courses using Design Heuristics     

Jin Woo Lee  Anastasia Ostrowski  Aileen Huang-Saad  Colleen M. Seifert 《European Journal of Engineering Education》2019,44(3):360-378

ABSTRACT

With increasing demand for improved medical equipment and healthcare, next-generation biomedical engineers need strong design skills. Equipping biomedical engineering students with tools for idea generation and development can increase student design success. Design Heuristics are an ideation tool developed through empirical studies of product designs. While identified in the mechanical engineering space, Design Heuristics may be applicable in biomedical engineering design. In our study, we implemented a Design Heuristics session during upper-level undergraduate and first-year graduate biomedical engineering design courses. We examined the applicability of Design Heuristics within individual and team concept generation contexts. The findings demonstrated that biomedical engineering students were able to use Design Heuristics to generate multiple concepts, and that initial concepts produced using Design Heuristics were carried over into final team design. The results support the applicability of Design Heuristics to student idea generation in biomedical engineering design.  相似文献   

From a Means to an End: Patenting in the 1999 Danish ‘Act on Inventions’ and its Effect on Research Practice     

Nadja Sejersen  Janus Hansen 《Minerva》2018,56(3):261-281

This paper examines the potential pitfalls for academic research associated with goal displacements in the implementation of goals and indicators of research commercialization. We ask why patenting has come to serve as the key policy indicator of innovative capacity and what consequences this has for the organization of academic research. To address these questions, the paper presents a case study from Denmark on, firstly, why and how the 1999 Danish ‘Act on Inventions’ introduced patenting as a central instrument to Danish science policy and, secondly, the effects the Act has had on Danish university organization and research practices. We trace why and how commercialization was introduced as an important objective in Danish science policy since the 1980s. The increased focus on patents is explained as an isomorphic adjustment to an international ‘science policy field,’ manifested in particular through OECD statistics, where patenting has come to serve as a key metric in international rankings. In a second step, we examine what effects the patenting requirements have had on organization and research practice at a Danish university. We show that in practice ‘number of patents’ changed from serving as an indicator of innovative capacity to being a policy goal in itself, thus in effect producing a goal displacement that is potentially damaging for both academic research and innovation capacity of the surrounding society. As a consequence of this goal displacement, active scientists now increasingly engage in patenting primarily as a means to fulfill organizational targets and to increase their ‘fundability,’ rather than to promote commercial applications of their research. In conclusion, we discuss how these unfulfilled policy ambitions have led to a retrospective redefinition of policy goals rather than an adjustment of the actual policy tools.  相似文献   

Situated Knowledge Production,International Impact: Changing Publishing Practices in a German Engineering Department     

Wolfgang Kaltenbrunner 《Minerva》2018,56(3):283-303

In this paper, I analyze how recent calls to internationalize publication behavior affect research practices at an automotive engineering department in Germany. Automotive engineering is a field with traditionally rather scarce publication activity and strong connections to industry. Substantial authority to define suitable research problems and ways of organizing knowledge production on a daily basis was therefore reserved for local academic elites as well as corporate partners. However, as engineers are increasingly expected to prove their performance through publishing in international peer-reviewed journals, the judgment as to what should be considered “interesting” or “robust” research is partly relegated to a gradually globalizing community of academic peers. This generates a variety of tensions with established ways of coordinating epistemic work at the department studied here. For example, the thematic interests of journals tend to exert a disruptive centrifugal pull in the context of an otherwise highly modular research culture, and possibilities to publish in international venues are unequally distributed across individual research projects. But while department members agree that there is a lack of fit between current practices and new expectations towards their publishing behavior, their opinions about the conclusions that should be drawn differ significantly. Some researchers argue that profound organizational changes are necessary to foster the academic rigor of German engineering research. Others believe that evaluation criteria should simply be adapted. This situation is arguably characteristic for research areas with a traditionally strong orientation to local stakeholders, and it suggests a need for more deliberative, participatory approaches to research evaluation in such fields.  相似文献
