The value of innovation: The interaction of competition, R&D and IP     

Christine Greenhalgh 《Research Policy》2006,35(4):562-580

This paper analyses market valuations of UK companies using a new data set of their R&D and IP activities (1989-2002). In contrast to previous studies, the analysis is conducted at the sectoral-level, where the sectors are based on the technological classification originating from Pavitt [Pavitt, K., 1984. Sectoral patterns of technical change. Research Policy 13, 343-373]. The first main result is that the valuation of R&D varies substantially across these sectors. Another important result is that, on average, firms that receive only UK patents tend to have no significant market premium. In direct contrast, patenting through the European Patent Office does raise market value, as does the registration of trade marks in the UK for most sectors. To explore these variations the paper links competitive conditions with the market valuation of innovation. Using profit persistence as a measure of competitive pressure, we find that the sectors that are the most competitive have the lowest market valuation of R&D. Furthermore, within the most competitive sector (‘science based’ manufacturing), firms with larger market shares (an inverse indicator of competitive pressure) also have higher R&D valuations, as well as some positive return to UK patents. We conclude that this evidence supports Schumpeter by finding higher returns to innovation in less than fully competitive markets and contradicts Arrow [Arrow, K., 1962. Economic welfare and the allocation of resources for invention. In: Nelson, R. (Ed.), The Rate and Direction of Inventive Activity. Princeton University Press, Princeton], who argued that, with the existence of IP rights, competitive market structure provides higher incentives to innovate.  相似文献   

CSRP's Impact on low-income preschoolers' preacademic skills: self-regulation as a mediating mechanism     

Raver CC  Jones SM  Li-Grining C  Zhai F  Bub K  Pressler E 《Child development》2011,82(1):362-378

Based on theoretically driven models, the Chicago School Readiness Project (CSRP) targeted low-income children's school readiness through the mediating mechanism of self-regulation. The CSRP is a multicomponent, cluster-randomized efficacy trial implemented in 35 Head Start-funded classrooms (N = 602 children). The analyses confirm that the CSRP improved low-income children's self-regulation skills (as indexed by attention/impulse control and executive function) from fall to spring of the Head Start year. Analyses also suggest significant benefits of CSRP for children's preacademic skills, as measured by vocabulary, letter-naming, and math skills. Partial support was found for improvement in children's self-regulation as a hypothesized mediator for children's gains in academic readiness. Implications for programs and policies that support young children's behavioral health and academic success are discussed.  相似文献   

Effect of foster care on young children's language learning     

Windsor J  Benigno JP  Wing CA  Carroll PJ  Koga SF  Nelson CA  Fox NA  Zeanah CH 《Child development》2011,82(4):1040-1046

This report examines 174 young children's language outcomes in the Bucharest Early Intervention Project, the first randomized trial of foster placement after institutional care. Age of foster placement was highly correlated with language outcomes. Placement by 15 months led to similar expressive and receptive language test scores as typical age peers at 30 and 42 months. Placement from 15 to 24 months also led to dramatic language improvement. In contrast, children placed after 24 months had the same severe language delays as children in institutional care. Language samples at 42 months confirmed that placement after 24 months led to lower expressive skill.  相似文献

Nutrition for winter sports     

Meyer NL  Manore MM  Helle C 《Journal of sports sciences》2011,29(Z1):S127-S136

Winter sports are played in cold conditions on ice or snow and often at moderate to high altitude. The most important nutritional challenges for winter sport athletes exposed to environmental extremes include increased energy expenditure, accelerated muscle and liver glycogen utilization, exacerbated fluid loss, and increased iron turnover. Winter sports, however, vary greatly regarding their nutritional requirements due to variable physiological and physique characteristics, energy and substrate demands, and environmental training and competition conditions. What most winter sport athletes have in common is a relatively lean physique and high-intensity training periods, thus they require greater energy and nutrient intakes, along with adequate food and fluid before, during, and after training. Event fuelling is most challenging for cross-country skiers competing in long events, ski jumpers aiming to reduce their body weight, and those winter sport athletes incurring repeated qualification rounds and heats. These athletes need to ensure carbohydrate availability throughout competition. Finally, winter sport athletes may benefit from dietary and sport supplements; however, attention should be paid to safety and efficacy if supplementation is considered.  相似文献

Beyond Cost Justification: Evaluation Frameworks in Corporate Distance Training     

Christine M. Keen  Zane L. Berge 《Performance Improvement》2014,53(10):22-28

Evaluation remains one of the biggest challenges for workplace training professionals today. Few organizations have mastered training evaluation, with even fewer moving beyond assessing learner reaction and satisfaction. The introduction of technology‐based distance training, coupled with large initial investments in technologies that are needed to support distance training programs, has further exacerbated evaluation efforts for training organizations. This article looks at the changing environment of training evaluation and the application of evaluation methodology in corporate distance training.  相似文献   

Action learning for professionals: a new approach to practice     

Christine Abbott  Cathy Mayes 《Action Learning: Research and Practice》2014,11(1):72-80

Following on from the article ‘Building Capacity in Social Care: An Evaluation of a National Programme of Action Learning Facilitator Development’ (Abbott, C., L. Burtney, and C. Wall. 2013. Action Learning: Research & Practice 10 (2): 168–177), this article describes how action learning is being introduced in Cornwall Council, UK and explores the relationship between social work and action learning in practice. In essence social work needs to perform well and achieve positive outcomes for users of its services. Cornwall Council's Children's Social Work and Psychology Services is introducing action learning for professionals as a new approach to practice.  相似文献   

Qualifizierungsstrategien deutscher Unternehmen in Japan,Indien und China – Deutsche Vorbilder oder einheimische Verfahrensweisen?

For many years the possible introduction of the German dual vocational education programme into other countries has been discussed. The transferability of the German vocational education and training system into other countries has been controversially discussed in the work of development assistance and in international comparative vocational education research for a long time, even though the empirical basis is quite narrow. The present study focuses on the vocational and training behaviours of German corporations in their subsidiaries in Japan, China and India. Even though all three nations are important countries for the German corporations the culture, the vocational education and employment systems are very different. Based upon the theory of the EPRG model in international management, this study analyses the vocational education and training activities and in terms of the EPRG model by interviews with experts. The findings indicate that a polycentric approach is used exclusively in India and to a significant extent in China. In Japan, in addition to the prevalent polycentric approach, there is also a strong influence of geocentric training styles. The similarities can be partly explained by the stronger focus on theoretical training institutions and a more academic attitude in society as a whole, which means that purely vocational training plays a marginal role with low esteem. In this context, it would be difficult to implement the German style of vocational education and training.  相似文献
