In this paper, we argue that a fundamental cultural shift is needed to effectively address anthropogenic causes of climate change. Evidence suggests that youth are well positioned to create such transformation. While various studies have contributed empirical evidence to numerous youth-based non-formal environmental engagement programmes, what is missing in the environmental education literature is discussion of a systematic approach to the development and evaluation of these programs. In this paper, we draw on the youth civic engagement literature to propose a framework that can be used as a basis to guide further development of evidence-based practices. Five major components are described as follows: (1) the engagement activity; (2) the engagement process; (3) initiating and sustaining factors; (4) mediators and moderators; and (5) outcomes. This approach to youth engagement can inform both researchers trying to study effective ways of creating change and practitioners developing environmental programmes that aspire towards a culture of sustainability. 相似文献

Startup size and the mechanisms of external learning: increasing opportunity and decreasing ability?
An important area of investigation in the field of entrepreneurship examines how people and organizations exploit technological opportunities. Prior research suggests that alliances, the mobility of experts, and the informal mechanisms associated with geographic co-location can present firms with useful opportunities to source technological knowledge. This paper uses insights from strategic management and organizational theory to suggest that organizational size may have an important impact on the extent of external learning, since it differentially affects the likelihood of learning via formal and informal mechanisms.Examining a cross-section of semiconductor startups, we find that external learning increases with startup size. With regard to the specific mechanisms of learning, we find that firms learn from alliances regardless of their size. For the informal mechanisms of mobility and geographic co-location, however, learning decreases with firm size. These results suggest that as startups grow, they may have increasing opportunities to access and exploit external knowledge, but their motivation (and hence ability) to learn from more informal sources may decrease. 相似文献

Abstract Current knowledge of the integration of children with specific language impairment (SLI) is examined. The paper begins by defining this group of children and the nature of their difficulties. The heterogeneous characteristics of SLI children are discussed. It then addresses the educational provisions made for SLI children and the opportunities for integration present in different models of provision. Research on the integration of SLI children is evaluated with particular emphasis on the difficulties encountered by this group of children. The paper concludes with some thoughts for future research. 相似文献
