This is one of the first studies to examine the educational entrepreneur in K-12 public schools and the first to present an instrument designed to measure entrepreneurial thinking among teachers using a type of reasoning, effectual reasoning, which has been proposed in the business literature on entrepreneurs. This study situates entrepreneurial thinking within the K-12 education arena and examines the relationship between high school and middle school teachers’ use of effectual reasoning and their corresponding implementation of high, medium, or low levels of innovation in STEM areas within their classrooms, districts, or across districts. Our findings correlated higher use of effectual reasoning, a component of entrepreneurial thinking, with higher levels of implementation of innovations among teachers within an NSF grant, Entrepreneurial Leadership in STEM Teaching and learning, which centered on deeper content, reform-oriented pedagogies, and entrepreneurial thinking. We found that high innovators viewed uncertainty’ differently than low innovators by associating it with more positive cognitive structures and that innovators at different levels hold distinct notions of what constitutes high and low risk innovations. Contrary to the common notion that entrepreneurs are high-risk takers, results reveal that the types of innovations perceived by high innovators as low risk are viewed as high risk by low innovators. Furthermore, the results are consistent with the idea that entrepreneurs do certain types of things to lower/manage the risk of innovations before and, if necessary, during the implementation of an innovation.

Evaluation of developmentally disabled persons for physical signs of sexual abuse presents many challenges to the practitioner. This group is especially vulnerable to all types of abuse. A group of 35 mentally retarded females from a residential treatment facility was examined by the child abuse medical team at Harbor/UCLA Medical Center after one inpatient was found to be pregnant. Patients ranged in age from 13 to 55 years (median, 26 years; mean, 31.3 +/- 13.6 years). All of the women had some degree of disability, with 24 (69%) being categorized as profoundly retarded. No patient was able to provide a history. There were 13 (37%) patients who had genital findings we believe are consistent with prior vaginal penetration. Dilemmas which arose during evaluation included the significance of healed genital lesions in this population and the implications of the findings for the residential facility. While developmentally disabled persons need an advocate in the medical and legal systems, these patients can overwhelm the practitioner. Whenever possible, a team approach is recommended to decrease the work load and frustration and provide collegial support and affirmation of findings. 相似文献

In the study, based on a representative sample of 26,670 Italian fifth-grade students, the authors examine the academic motivational profiles of immigrant and native students, as well as of boys and girls. To reliably estimate mean differences, the measurement invariance of a short version of the Academic Self-Regulation Questionnaire was first established across the groups. Boys reported less autonomous motives for studying than girls while first-generation immigrant pupils showed higher levels of intrinsic motivation, identified regulation, and external regulation for studying than natives did. Also, second-generation immigrants had higher levels of academic motivation than natives did, although they were less motivated and reported less autonomous reasons for studying than first generations. While confirming the immigrant paradox in a country with a rapidly increasing level of immigrant students, findings show that second-generation immigrants not only report a lower quantity of motivation than first-generations, but also appear to have a different quality of motivation. 相似文献

The problem of environmental monitoring aimed at identifying and evaluating the weathering mechanisms affecting historical stoneworks is here discussed and a methodology based on the use of already available, long record, urban-scale environmental data is proposed. An example of its application to the Cathedral of Modena (Italy, XII-XIV century, included in the UNESCO's World Heritage List) is then presented. In this case, the methodology allowed the identification of the main degradation causes, which found significant confirmation by material diagnostics on the available samples and finite element structural modelling. Thanks to the decay causes identification allowed by the proposed methodology, more effective restoration procedures can be outlined. 相似文献

Research on University-industry (U-I) linkages and their determinants has increased significantly in the past few years. However, there is still controversy on the key factors explaining the formation of U-I linkages, and especially related to individual researcher characteristics. This paper provides new empirical evidence and, in particular, looks at the importance of researchers’ individual characteristics and their institutional environments in explaining the propensity to engage in different types of U-I linkages. Based on an original dataset, we present new evidence on three wine producing areas - Piedmont, a region of Italy, Chile and South Africa - that have successfully responded to recent structural changes in the industry worldwide. Empirical findings reveal that researchers’ individual characteristics, such as centrality in the academic system, age and sex, matter more than publishing records or formal degrees. Institutional specificities at country level also play a role in shaping the propensity of researchers to engage with industry. 相似文献

Assessing the contribution to innovation of private equity investors: A study on European buyouts 总被引:1,自引:0,他引:1
Elisa Ughetto 《Research Policy》2010,39(1):126-140
The paper provides an empirical analysis of the patenting activity of a sample of Western European manufacturing firms undergoing a buyout between 1998 and 2004. A panel data design is used to test whether the characteristics of the deal and of private equity (PE) firms can affect acquired companies’ subsequent innovation effort as measured by the number of patents granted by the EPO. Results support the view that the innovation activity of portfolio firms is affected by different types of investors, pursuing different objectives and differing in their risk propensity, expected returns and investment policies. The characteristics of lead investors (size, stage specialization, geographical location) and of the deal (amount invested, presence of multiple investors) are also investigated and are found to differently affect the post-buyout innovation activity of sample firms. 相似文献
