This paper presents a synthetic framework identifying the central drivers of start-up commercialization strategy and the implications of these drivers for industrial dynamics. We link strategy to the commercialization environment—the microeconomic and strategic conditions facing a firm that is translating an “idea” into a value proposition for customers. The framework addresses why technology entrepreneurs in some environments undermine established firms, while others cooperate with incumbents and reinforce existing market power. Our analysis suggests that competitive interaction between start-up innovators and established firms depends on the presence or absence of a “market for ideas”. By focusing on the operating requirements, efficiency, and institutions associated with markets for ideas, this framework holds several implications for the management of high-technology entrepreneurial firms. 相似文献

从经济学角度重新审视美国教育的公共目的 总被引:3,自引:0,他引:3
教育是公共产品还是私人产品近年来受到广泛的讨论,本文从经济学的角度回顾了美国教育的目的。中小学教育的公共性主要体现在公民教育;高等教育的公共性主要体现在知识创造和文化传承;职业教育的公共性主要体现在培养合格的劳动者。教育应该重新强调其公共性。 相似文献

For more than a century, community colleges have provided a postsecondary education alternative to the traditional, 4-year university. Enrolling disproportionate numbers of both disadvantaged and nontraditional students, the community college sector has seen unparalleled gains in enrollment over the past few decades. Along with these increases in enrollment, there has been a shift in focus toward transfer to 4-year institutions, as well as the development of articulation agreements. Established in order to ease the transfer process from community colleges to 4-year colleges/universities—for those students interested in obtaining a bachelor’s degree—these agreements currently exist in more than 30 states. Via two-level, hierarchical linear modeling, this article examines the student and school level characteristics of community colleges that affect transfer and bachelor’s degree attainment rates. Also examined is the impact of articulation agreements. Ultimately, while articulation agreements are not found to yield a significant effect on transfer rates, they are found to have significant, positive effects on bachelor’s degree attainment rates. 相似文献

Nature centers can serve as valuable community institutions if they are seen as providing important services to the community. Through survey research in communities surrounding 16 nature centers in the United States, we examine the attitudes, behaviors, and beliefs that drive hypothetical support for nature centers from local residents. Respondents who recognized centers as institutions that provide opportunities for leisure and connection with nature; contribute to civic engagement; and bolster local economies, community pride, and aesthetics reported the greatest likelihood of donating, volunteering, or responding to threats at local centers. Additional predictors of support included positive evaluations of staff members, perceptions of positive attitudes toward the center held by other community members, familiarity with center activities, pro-environmental attitudes, and past donation or volunteering. The findings highlight the potential returns for centers that expand their activities and operations beyond more traditional roles of providing nature-based outdoor recreation and environmental education experiences. 相似文献

Although attachment theory has long posited a link between early experiences of care and children's prosocial behavior, investigations of this association have not embraced the multifaceted nature of prosociality. This study is the first to assess associations between child attachment and independent observations of helping, sharing, and comforting. Attachment quality in 3- to 5-year-old children (N = 137) was linked to all three prosocial behaviors. Additionally, bifactor analyses revealed distinct associations between attachment and children's general prosocial dispositions and their specific abilities to meet the unique challenges of helping and, marginally, comforting. These findings underscore the importance of considering multiple explanations for links between attachment and prosocial behavior and provide novel insights into sources of variation in children's prosociality. 相似文献

This investigation examines the use of structural equation modeling (SEM) procedures to develop and validate scales to measure environmental responsibility, character development and leadership, and attitudes toward school for environmental education programs servicing middle school children. The scales represent outcomes commonly of interest to environmental education programs and also to after‐school and positive youth development activities. First, we developed the scales using confirmatory factor analysis (CFA) and then we used multi‐group longitudinal CFA to cross‐validate the model with data collected before participation in the environmental education program, immediately after the program, and three months later. The results support a three‐factor model, producing three scales that appear to be valid and reliable. 相似文献

The tensions between environmental protection and economic growth are critical to future well-being, and it is therefore important to understand how young people conceptualize these tensions. The aim of the present study is to explore students’ solutions to the dilemma of economic development and mitigating climate change, with regard to societal responses to the challenge of climate change. The study was conducted in China’s Green Schools. Green School is an international long-term programme with the aim of increasing students’ knowledge of environmental issues, and transferring this knowledge into positive actions to affect the wider community. The data were obtained through semi-structured pre- and post-interviews with 15–16-year-old students in three groups (12 students) from Green Schools in the Beijing area. The results show that students’ discussions focused exclusively on economic growth and social welfare. Students seem to believe that environmental problems are inevitable, nature is a ‘box’ of resources, and economic development is necessary in order to sustain and even improve nature. Therefore, there is no dilemma between economic development and environmental protection. The paper ends with a discussion on research and implications for teaching climate change. 相似文献

The achievement gap in many developing countries is defined in terms of rich/poor and public/private. The prevailing explanation for the “developing” achievement gap is an underfunded, inefficient, and/or inadequately supplied public school sector. Via an analysis of a Colombian voucher experiment, this article examines the extent to which income-contingent vouchers can narrow the achievement gap and provide a cost-effective method for increasing secondary school enrollments. Despite structural and implementation flaws, which diminish the program's impact on achievement and enrollments, its successes strengthen the argument that implementing an income-contingent voucher program can help narrow the achievement gap in developing countries. To cost-effectively increase enrollments, however, significant modifications and expansions to the program would be necessary—as explained in the conclusion of this article. 相似文献
