Governments as partners: The role of alliances in U.S. cleantech startup innovation     

Claudia Doblinger  Kavita Surana  Laura Diaz Anadon 《Research Policy》2019,48(6):1458-1475

Accelerating innovation in clean energy technologies is a policy priority for governments around the world aiming to mitigate climate change and to provide affordable energy. Most research has focused on the role of governments financing R&D and steering market demand, but there is a more limited understanding of the role of direct government interactions with startups across all sectors. We propose and evaluate the value-creation mechanisms of network resources from different types of partners for startups, highlighting the unique resources of government partners for cleantech startups. We develop and analyze a novel dataset of 657 U.S. cleantech startups and 2,015 alliances with governments, firms, research organizations, and not-for-profit organizations from 2008 to 2012 and analyze short-term firm outcomes from the different alliances. Our findings highlight the importance of governmental partners in technology development alliances to catalyze cleantech startup innovation (the patenting activity of cleantech startups increases by 73.7 percent with every additional governmental technology alliance when compared to those startups that did not engage in such alliances) and as quality signals to private sector investors for licensing alliances (private financing deals increase by 155 percent for every additional license from a government organization). Overall, these findings extend the alliance perspectives on innovation, contribute to the emerging research on entrepreneurial ecosystems, and underline the need to develop empirical evidence in different sectors.  相似文献

Stefano Cacciamani  Daniela Villani  Andrea Bonanomi  Claudia Carissoli  Maria Giulia Olivari  Laura Morganti 《Journal of Research on Technology in Education》2018,50(2):120-133

To maximize the advantages of the tablet personal computer (TPC) at school, this technology needs to be accepted by students as new tool for learning. With reference to the Technology Acceptance Model and the Unified Theory of Acceptance and Use of Technology, the aims of this study were (a) to analyze factors influencing high school students' acceptance of TPCs and (b) to detect any difference in this influence considering the frequency of TPC use, students' gender, and school grade. Two hundred and ninety-six students from six high schools in the Milan area participated in the study. Data were collected using an online survey. The results showed that empowerment in learning, perceived usefulness, and support conditions affect learning use, and empowerment in learning and affect influence communicative use of TPCs. The implications of these results are discussed. (Keywords: tablets, acceptance, digital technologies, high school, path analysis)  相似文献   

The exercise effect on psychological well-being in older adults—a systematic review of longitudinal studies     

Inna Bragina  Claudia Voelcker-Rehage 《Sportwissenschaft》2018,48(3):323-333

The aim of this systematic review was to investigate the longitudinal relationship between physical activity (PA) and the psychological domains of well-being in older adults and to identify possible moderators and mediators of this relationship. Twelve longitudinal investigations were included in this review. The results indicate that there seems to be a positive association between PA and psychological well-being over time. Thus PA may be one possible individual lifestyle factor for the long-term promotion of psychological well-being in older adults. Especially leisure time PA at light intensities conducted in group settings was identified to be beneficial for promoting psychological well-being. Furthermore, longitudinal results indicated that self-efficacy, self-esteem, affect, optimism, and pre-interventional motivation moderated/mediated the relationship between PA and psychological well-being in older adults.  相似文献

Evaluating Interventions with Multimethod Data: A Structural Equation Modeling Approach     

Claudia Crayen  Christian Geiser  Herbert Scheithauer  Michael Eid 《Structural equation modeling》2013,20(4):497-524

In many intervention and evaluation studies, outcome variables are assessed using a multimethod approach comparing multiple groups over time. In this article, we show how evaluation data obtained from a complex multitrait–multimethod–multioccasion–multigroup design can be analyzed with structural equation models. In particular, we show how the structural equation modeling approach can be used to (a) handle ordinal items as indicators, (b) test measurement invariance, and (c) test the means of the latent variables to examine treatment effects. We present an application to data from an evaluation study of an early childhood prevention program. A total of 659 children in intervention and control groups were rated by their parents and teachers on prosocial behavior and relational aggression before and after the program implementation. No mean change in relational aggression was found in either group, whereas an increase in prosocial behavior was found in both groups. Advantages and limitations of the proposed approach are highlighted.  相似文献   

Success factors impacting Latina/o persistence in higher education leading to STEM opportunities     

Claudia Peralta  Melissa Caspary  Diane Boothe 《Cultural Studies of Science Education》2013,8(4):905-918

This study investigates how Latina/Latino youth resist, conform to, and persist in schooling, and explores their preparation for an education in science, technology, engineering and math (STEM) fields. Using Latino Critical Race Theory as a framework, evidence of the “sticky mess” of racial inequalities (Espinoza and Harris in Calif Law Rev 10:499–559, 1997) and the concept of community cultural wealth (Yosso in Race Ethn Educ 8:69–91, 2005) will be used to understand how Latina/o students successfully persist in college. Quantitative and qualitative findings collected at two public universities in 2007–2012 show that Latina/o parents play a significant role in influencing their children’s decision to attend college; family, friend and community support and hard work have also been instrumental in college success. This is evident through parents’ encouragement to persist, expectations to do well and students serving as role models for siblings and peers. As policy makers in the educational arena emphasize STEM fields, there is a significant opportunity for Latino students to make valuable contributions.  相似文献   

Fostering Cooperative and Competitive Competencies of Non-business Graduates by Economic Education     

Ewald Mittelstaedt  ;Claudia Wiepcke 《美中教育评论》2011,(2):157-164

In the course of the European Bologna process, the notion of employability becomes increasingly important for universities. Graduates are in particular employable, if they exactly possess those abilities and skills, which are required by employers. Studies show that in the context of recruiting university graduates, employers do not only pay attention to expertise and soft skills, but also care about knowledge referring to products, markets, customers and competitors of their relevant industry. Employers increasingly expect economic knowledge as well as its application which is also expected by graduates, who have not completed a course of studies in economics or business administration. At this point, business skills take on greater significance. Whereas the expertise normally is achieved by completing a course of studies at university and soft skills are incorporated in a cross-section of universities, business skills are not. The article discusses, in what way, cooperative and competitive skills are predestined for enhancing the employability of graduates. With regard to business education and ethics, particular attention should be paid to the concept of competency as well as the self-determined taking on of one＇s own position. An inclusion of economic educational modules as a part of extracurricular studies can, by means of its practical with use-oriented focus, not only improve employability, but also form the basis of a reflexive professional life.  相似文献   

Die Umwegrentabilit?t einer Hochschule am Beispiel der FH JOANNEUM Campus Kapfenberg     

Claudia Brandst?tter  Marta Jordan  Richard Treutler  Martina Pretterer 《Zeitschrift für Hochschulrecht, Hochschulmanagement und Hochschulpolitik: zfhr》2011,10(2):63-69

Hochschulen verursachen nicht nur Kosten, sondern generieren auch einen erheblichen Nutzen, da sie Geld- und Güterstr?me zwischen der ?ffentlichen Hand, Privatpersonen und Unternehmen in Gang setzen. Daraus resultieren tangible (in Geldwerten messbare) und intangible (nicht in Geldwerten messbare) Effekte, die durch den Betrieb einer Hochschule entstehen. Diese Auswirkungen wurden für den Standort Kapfenberg der FH JOANNEUM erhoben. Aus der durchgeführten Analyse ergeben sich folgende Effekte: aus kurzfristiger Sichtweise flie?en j?hrlich fast 3,0 Mio. € der Region Bruck/Mur-Kapfenberg zu, der mittelfristig in der Region verbleibende Kaufkraftanteil betr?gt über 2,0 Mio. € und aus langfristiger Perspektive werden durch das Bestehen der FH JOANNEUM Campus Kapfenberg fast 3,6 Mio. € an zus?tzlichem Einkommen in der Region Bruck/Mur-Kapfenberg induziert. Daneben entstehen durch die Existenz einer Hochschule auch noch positive Effekte für eine Region, die nicht eindeutig quantifizierbar sind.  相似文献
