Economic theory views patents as policy instruments aimed at fostering innovation and diffusion. Three major implications are drawn regarding current policy debates. First, patents may not be the most effective means of protection for inventors to recover R&D investments when imitation is costly and first mover advantages are important. Second, patentability requirements, such as novelty or non-obviousness, should be sufficiently stringent to avoid the grant of patents for inventions with low social value that increase the social cost of the patent system. Third, the trade-off between the patent policy instruments of length and breadth could be used to provide sufficient incentives to develop inventions with high social value. Beyond these three implications, economic theory also pleads for a mechanism design approach: an optimal patent system could be based on a menu of different degrees of patent protection where stronger protection would involve higher fees, allowing self-selection by inventors. 相似文献

Based on a survey of the inventors of 9017 European patented inventions, this paper provides new information about the characteristics of European inventors, the sources of their knowledge, the importance of formal and informal collaborations, the motivations to invent, and the actual use and economic value of the patents. 相似文献

In this case study our aim was to gain more insight in the possibilities of qualitative formative peer assessment in a computer supported collaborative learning (CSCL) environment. An approach was chosen in which peer assessment was operationalized in assessment assignments and assessment tools that were embedded in the course material. The course concerned a higher education case‐based virtual seminar, in which students were asked to conduct research and write a report in small multidisciplinary teams. The assessment assignments contained the discussion of assessment criteria, the assessment of a group report of a fellow group and writing an assessment report. A list of feedback rules was one of the assessment tools. A qualitative oriented study was conducted, focusing on the attitude of students towards peer assessment and practical use of peer assessment assignments and tools. Results showed that students’ attitude towards peer assessment was positive and that assessment assignments had added value. However, not all students fulfilled all assessment assignments. Recommendations for implementation of peer assessment in CSCL environments as well as suggestions for future research are discussed. 相似文献

The purpose of this study is to examine the effects of email modeling and scaffolding on the social writing quality of students with cognitive disabilities. Ten students from a university-affiliated lab school (mean age = 19.3; SD = 1.2) with an average of IQ of 55.30 (SD = 5.98) and 10 teacher candidates in a university teacher education programme participated in the study. The results suggest that all students with intellectual disabilities were able to holistically improve their social writing quality after exchanging emails with mature writers over a period of 15 weeks. Specifically, the students progressively showed various degrees of improvement in the areas of writing mechanics, lexical and syntactic complexity, writing cohesion, pragmatic propriety and writing motivation. However, the figurative use of language remained unaffected by the email modeling and scaffolding. Taken together, this study suggests that Internet-mediated formats, such as email, can reduce the anxiety of students with intellectual disabilities. Students feel more motivated to engage in writing and do so more actively in social media exchanges, thus improving their virtual social communication skills through writing. Teaching implications of this study are discussed. 相似文献

The purpose of this study is to examine the interactive effect of worldviews and media frames on policy preference. Using flooding as a case study, we examine the interplay of ecological worldviews and news framed as either emphasizing harmony with nature or mastery over nature on individuals' preference for flood protection policy. A total of 255 undergraduate students participated in a 2 (ecological worldviews: balance-with-nature vs. human-domination-over-nature) × 2 (media frames: harmony frame vs. mastery frame) between-subjects experiment. The findings indicate that both the balance-with-nature worldview and the human-domination-over-nature worldview have significant impacts on preference for flood protection policy. Furthermore, the harmony frame amplified the effect of the balance-with-nature worldview in supporting a natural approach to flood protection. In contrast, the mastery frame amplified the effect of the human-domination-over-nature worldview on the preference for a structural approach to flood protection. Implications are discussed. 相似文献

Previous research has demonstrated that compliance‐gaining strategies can he arrayed on an unidimensional continuum, anchored by positive, pro‐social strategies and negative, antisocial strategies (Hunter & Boster, 1987; Rolojf & Barnicott, 1978, 1979). Individual differences, including argumentativeness and verbal aggression (Boster & Levine, 1988), have been shown to affect one's ethical threshold. This ethical threshold is consistent with a Guttman simplex and determines both how many, as well as how antisocial, compliance‐gaining strategies individuals may consider using. Activists, who are highly involved and committed to their cause and who tend to be less verbally aggressive and more argumentative than the general public (Campo, 1999), are likely to have a lower threshold and to use more strategies. This study examines to what extent activism predicts one's ethical threshold, when controlling for the known effects of argumentativeness, verbal aggressiveness, and sex. Participants (N = 454) at two separate universities completed a repeated measures questionnaire that asked them to indicate their likelihood of use of 25 separate compliance‐gaining strategies. Based on respondents’ likelihood of use of these 25 strategies, the data were consistent with a Guttman simplex. A multiple regression model was tested, and indicated that one's ethical threshold is directly predicted by level of activism and verbal aggressiveness. Sex and argumentativeness were not found to be significant predictors in this revised model. In addition, activists used more strategies than non‐activists. Implications for advancing research related to activism and compliance‐gaining strategy selection are discussed. 相似文献

Our current knowledge society does not only have an impact on labour market demands, but its citizens also have to cope with increasing social demands. A growing number of vulnerable adults lack basic competences and therefore risk social exclusion. In this respect, The European Commission as well as the OECD agree that adult education can play a significant role in increasing social inclusion of vulnerable adults. However, to date, evidence of outcome of adult education programmes in terms of social inclusion is hardly available. The present study aims to unravel the complexity of the phenomenon of adult education to enhance participants’ social inclusion. Using a phenomenographic approach, we have explored different experiences of 32 vulnerable adults who have participated in adult education courses. The results show that an increase on an individual level (activation and internalisation) is more often perceived by the interviewees than an increase on the collective level of social inclusion (participation and connection). To ensure successful results and to improve quality of the lifelong learning process it seems that particularly the variables teacher support, life circumstances, and learning contents and activities are important elements to enhance the transfer aiming to increase social inclusion. 相似文献
