We investigate two fundamental research questions related to the funding of early-stage technology enterprises. First, does presentation design, and the presenting entrepreneur's passion and preparedness, influence experts' assessment of the merit and commercialization potential of an emerging firm's technology? Second, are the entrepreneur's passion and preparedness during a formal presentation associated with future technology success? We analyze twenty-two video-taped presentations to a U.S. Department of Defense technology transfer and granting consortium, and track subsequent technology success. From the data it appears that both entrepreneurial passion and presentation design does influence expert assessment of a technology, and future commercialization success can be predicted to some extent by the level of entrepreneurial passion exhibited during the presentation. 相似文献

There have been a number of earlier investigations, using differing methodologies, into the extent to which teachers in the secondary school interact with boys and girls and the results have suggested an imbalance in the teachers’ verbal behaviour towards the genders that is quite similar to the imbalance found in teachers’ behaviour in the primary school. The main aim of this study was to devise an investigation using the same methodology as that used in a recent primary school investigation in order to be able to make a fair comparison between the two levels. The results showed considerable differences in the teachers’ verbal behaviour towards the genders in the secondary school from that of teachers in the primary school. Where the primary school data showed teachers interacting more with the boys than the girls and the boys being less on‐task than the girls, the secondary school data showed no such differences. 相似文献

Globalization has changed the way people behave in different aspects of life. One of the significant differences is that people
are now competing with everyone around the world, not just people within or near their own regions. A good way of remaining
competitive is to provide quality education that can help students meet the needs of the competitive economy. However, not
all nations are responding in the same way. Using a quantitative approach, this explorative study seeks to discover if, and
how, cultural dimensions fit into the process of meeting the demands of the competitive economy by means of education across
regions. Forty-three regions with different ratings on the Power Distance Index (PDI), Individualism (IDV), Masculinity (MAS),
and the Uncertainty Avoidance Index (UAI) are included in this study. The results show that UAI, PDI and IDV are significant
factors relating to this issue. 相似文献

OBJECTIVE: This study, using latent variable methodology, explores simultaneously the relative effects of childhood abuse and early parental substance abuse on later chronic homelessness, depression, and substance abuse problems in a sample of homeless women. We also examine whether self-esteem and recent violence can serve as mediators between the childhood predictors and the dysfunctional outcomes.METHOD: The sample consists of 581 homeless women residing in shelters or sober living centers in Los Angeles (54% African-American, 23% Latina, 22% White, mean age=33.5 years). Multiple-indicator latent variables served as predictors and outcomes in structural models. Childhood abuse was indicated by sexual, physical, and verbal abuse.RESULTS: Childhood abuse directly predicted later physical abuse, chronic homelessness, depression, and less self-esteem. Parent substance use directly predicted later substance use problems among the women. Recent physical abuse predicted chronic homelessness, depression, and substance use problems. Greater self-esteem predicted less depression and fewer substance use problems. Childhood abuse also had significant indirect effects on depression, chronic homelessness, and drug and alcohol problems mediated through later physical abuse and self-esteem.CONCLUSIONS: Although there was a strong relationship between childhood abuse and parent drug use, childhood abuse was the more pervasive and devastating predictor of dysfunctional outcomes. Childhood abuse predicted a wider range of problems including lower self-esteem, more victimization, more depression, and chronic homelessness, and indirectly predicted drug and alcohol problems. The mediating roles of recent physical abuse and self-esteem suggest salient leverage points for change through empowerment training and self-esteem enhancement in homeless women. 相似文献

Objective. This study examined the cognitive-affective strategies used by parents of young children with conduct problems to regulate emotions. Key questions concerned the extent to which these emotion regulation strategies are associated with positive and negative parenting practices and predict quality of parenting through interplay with parental depression. Design. Participants were families of toddlers (n = 84) referred to a tertiary-level health service for the treatment of disruptive behavior problems. Parenting practices were indexed through observational coding of parent–child interactions and self-report data on multiple dimensions of positive and negative parenting. Parents self-reported their use of cognitive reappraisal and expressive suppression—the two emotion regulation strategies that are most robustly associated with psychosocial functioning in adults. Results. Associations between emotion regulation strategy and quality of parenting were moderated by parental depressive symptom severity, with distinct effects seen for positive and negative parenting practices. In terms of positive parenting, more frequent use of cognitive reappraisal was associated with increased use of labeled praise among parents with lower levels of depressive symptoms, whereas parents who had higher levels of depressive symptoms engaged in less such praise regardless of how frequently they used reappraisal. In terms of negative parenting, frequent use of cognitive reappraisal and expression suppression were associated with reduced levels of negative parenting, but only among parents with high levels of depression. Conclusions. These findings add to growing support for the integration of emotion regulation strategies into family process models of early-onset conduct problems and related clinical interventions. 相似文献

New Caledonian crows make and use tools, and tool types vary over geographic landscapes. Social learning may explain the variation in tool design, but it is unknown to what degree social learning accounts for the maintenance of these designs. Indeed, little is known about the mechanisms these crows use to obtain information from others, despite the question’s importance in understanding whether tool behavior is transmitted via social, genetic, or environmental means. For social transmission to account for tool-type variation, copying must utilize a mechanism that is action specific (e.g., pushing left vs. right) as well as context specific (e.g., pushing a particular object vs. any object). To determine whether crows can copy a demonstrator’s actions as well as the contexts in which they occur, we conducted a diffusion experiment using a novel foraging task. We used a nontool task to eliminate any confounds introduced by individual differences in their prior tool experience. Two groups had demonstrators (trained in isolation on different options of a four-option task, including a two-action option) and one group did not. We found that crows socially learn about context: After observers see a demonstrator interact with the task, they are more likely to interact with the same parts of the task. In contrast, observers did not copy the demonstrator’s specific actions. Our results suggest it is unlikely that observing tool-making behavior transmits tool types. We suggest it is possible that tool types are transmitted when crows copy the physical form of the tools they encounter. 相似文献

Teachers' learning to facilitate high‐level student thinking: Impact of a video‐based professional development 下载免费PDF全文
Attaining the vision for science teaching and learning emphasized in the Framework for K‐12 Science Education and the next generation science standards (NGSS) will require major shifts in teaching practices in many science classrooms. As NGSS‐inspired cognitively demanding tasks begin to appear in more and more science classrooms, facilitating students' engagement in high‐level thinking as they work on these tasks will become an increasingly important instructional challenge to address. This study reports findings from a video‐based professional development effort (i.e., professional development [PD] that use video‐clips of instruction as the main artifact of practice to support teacher learning) to support teachers' learning to select cognitively demanding tasks and to support students' learning during the enactment of these tasks in ways that are aligned with the NGSS vision. Particularly, we focused on the NGSS's charge to get students to make sense of and deeply think about scientific ideas as students try to explain phenomena. Analyses of teachers' pre‐ and post‐PD instruction indicate that PD‐participants began to adopt instructional practices associated with facilitating these kinds of student thinking in their own classrooms. The study has implications for the design of video‐based professional development for science teachers who are learning to facilitate the NGSS vision in science classrooms. 相似文献
