This article considers the situation of women in science in Germany. We argue that scientific organizations play a crucial role in shaping science careers, often with different consequences for men and women. To sustain the argument, we offer a study of the careers of male and female scientists in the Max Planck Society. Our findings show that external support increases career options and opportunities for men, but not for women scientists. 相似文献

Companies realize innovations by creating and implementing new knowledge. One possible source of innovative ideas are new employees. Based on an existing game-theoretic model the conditions of efficient knowledge transfer in a team are analyzed. Offering knowledge to a colleague cannot be controlled directly by the company due to information asymmetries. Thus the management has to provide incentives, which motivate the employees to act in favor of the company. The aim of this paper is to show what influences the propensity of the employees to engage in knowledge transfer and how the management can design the incentive structure for optimal transfer. Several factors are relevant, especially the individual costs of participating in the transfer. These consist mainly of the existing absorptive capacity and the working atmosphere. The model is at least partly generalized on more players. The relevance of the adequate team size is shown: too few or too many developers decrease the remaining company profit. A further result is that depending on the cost structure, perfect knowledge transfer is not always best for the profit of the company. 相似文献

We compared the extent to which the long-term influence of family socioeconomic status (SES) on children's school performance from age 7 through 16 years was mediated by their preschool verbal and nonverbal ability. In 661 British children, who completed 17 researcher-administered ability tests at age 4.5 years, SES correlated more strongly with verbal than nonverbal ability (.39 vs. .26). Verbal ability mediated about half of the association between SES and school performance at age 7, while nonverbal ability accounted for a third of the link. Only SES, but not verbal or nonverbal ability, was associated with changes in school performance from age 7 to 16. We found that SES-related differences in school performance are only partly transmitted through children's preschool verbal abilities. 相似文献

This paper explains the application of concept mapping to help foster a learning-centred approach. It investigates how concept maps are used to measure the change in learning following a two-week intensive undergraduate Marketing Principles course delivered to 162 Chinese students undertaking a Bachelor of Business Administration programme in China. Using four scoring procedures (breadth of knowledge, relational quality, structural quality and holistic quality), student learning is assessed in terms of prior and new knowledge, as well as improvement in knowledge structure. Concept map scores are correlated with conventional measures of overall student performance. The results provide strong evidence for improvement in students’ ability to externalise new learned concepts resulting from intensive instruction. Incorporating concept maps as a contemporary method of learning in the curriculum potentially enriches student learning, provides a measure of the impact of teaching on students’ learning and adds value to students’ higher education experience. 相似文献

We analyse the utility of social capital for children’s achievement, and if this utility interacts with family human capital and the quality of the parent-child relationship. Our focus is on parental activities directly related to children’s school work. Our data stem from a Swedish cohort born in 1953 and consist of both survey and register data. We find that parents with more human capital tended to offer their children more social capital. OLS regressions showed that, when present, social capital was directly related to children’s grades and its utility for achievement did not depend on parents’ human capital. The utility of social capital was enhanced when combined with a very good parent-child relation. 相似文献

Innovation researchers have begun to look beyond how users develop tangible objects or product innovations and moved to investigate the existence and impact of intangible user-developed innovations in techniques and services in the household sector . In this paper, to incorporate technique and service innovations and other varieties of intangible innovations not yet described in the literature into an efficient and encompassing typology, we propose the new concept of intangible Behavioral Innovation as an overarching category that stands in contrast to tangible product innovation. Behavioral innovation is defined as consisting of one or a connected sequence of intangible problem-solving activities that provide a functionally novel benefit to its user developer relative to previous practice. We demonstrate in a pilot study using a relatively novel big data-gathering and semantic analysis approach that behavioral innovation exists and can be identified in user-generated content posted openly online in peer-to-peer discussion forums relating to household sector activities such as parenting. The preponderance (N = 138) of the 168 user innovations captured in our samples of discussion comments were intangible behavioral innovations, most of which were developed by women. The majority of behavioral innovations identified were diffused by their user developers in response to specific requests for help or advice from peers in their online community. Thus, incorporating the new concept of intangible behavioral innovation into studies of user innovation's scope and significance in the household sector can serve to clarify which users innovate in our communities of interest, what and how they innovate, why they are triggered to diffuse their innovations peer-to-peer, and how their innovative activities might impact social welfare. 相似文献
