This paper investigates the role of government R&D subsidy programs in stimulating knowledge spillovers. R&D subsidies are an effective public policy instrument when knowledge spillovers exist yet ex ante it is difficult to identify projects that have the greatest potential to increase innovation and economic growth. This paper derives a set of project and firm attributes that the literature finds generate knowledge spillovers and uses data on project proposals to estimate the degree to which a government R&D program conforms. We find that projects that were awarded R&D subsidies were more likely to have attributes such as participation in new research joint ventures and connections to universities and other firms. Following the post-award activities of firm, we find that receipt of a government R&D subsidy increased the funding from other sources when compared to firms that were not awarded funding. 相似文献

OBJECTIVE: Child sexual abuse (CSA) has been associated with adverse adult psychosocial outcomes, although some reports describe minimal long-term effects. The search for explanations for the heterogeneous outcomes in women with CSA has led to an examination of a range of CSA-related factors, from the severity of individual CSA incidents to the childhood family environment. This study compares three factors for predicting adult outcomes: a multidimensional CSA Severity Scale, the presence or absence of CSA, and family environment. METHODS: The effect of CSA on adult outcomes was examined among 290 community-dwelling women raised in intact families. Standardized measures and a focused interview were used to collect data, with siblings as collateral informants. RESULTS: Comparison of a multidimensional CSA Severity Scale to a dichotomous measure of the presence or absence of CSA showed that the Severity Scale did not have greater predictive value for adult outcomes than the dichotomous measure, nor was it as parsimonious. Childhood family environment scales added significantly to the predictive ability of the dichotomous measure. CONCLUSION: The specific characteristics of a CSA experience may be less important than the occurrence of CSA and the family environment of women for predicting long-term outcomes. 相似文献

Sex Differences in Neonatal Stress Reactivity 总被引：3，自引：0，他引：3
The question of whether a sexually dimorphic stress reaction exists prior to extensive socialization was addressed by examining sex differences in physiological and behavioral stress reactivity, in healthy, term neonates, after a mildly stressful behavioral assessment procedure. The Neonatal Behavior Assessment Scale (NBAS; Brazelton, 1973) was administered to 18 male and 18 female neonates. Heart rate (HR), salivary cortisol, and behavioral states were assessed before and after the exam. Sex differences included higher cortisol response in males and a greater change in HR and higher NBAS motor performance cluster score in females. Salivary cortisol, HR change, NBAS cluster scores, and behavioral states after NBAS provided 100% discrimination between male and female infants. These findings suggest that there are neonatal sex differences in behavioral and physiological stress reactivity prior to socialization. 相似文献

Over $18 billion is spent annually on professional development for in-service teachers. This study examined the focus, duration, and impact of professional development activities in which elementary (students ages 5–11) and middle school (students ages 11–14) teachers participated. Ninety-eight teacher-participants completed an online survey about their professional development experiences. In the analysis of literacy survey items and mathematics survey items, there were similarities in focus areas that received greater participation and areas that received less. There were also noticeable differences in frequency of participation in literacy and mathematics professional development. Comparisons between literacy and mathematics professional development indicated that more teachers reported participating in literacy experiences. This included workshops as well as ongoing support through planning meetings and mentorship. Overall, the consensus from teachers was that professional development was effective and has a beneficial impact on their classroom. Researchers share implications for the design and research of future professional development programs. 相似文献

This empirical study examined the relations between Afrocentric spirituality and psychological help-seeking attitudes, intentions, and stigma among Nigerian adults living in the United States of America (N = 122). Participants completed a demographic questionnaire, the Spirituality Scale (Jagers and Smith in Journal of Black Psychology, 22, 429–442, 1996), the Perception of Stigmatization by Others for Seeking Psychological Help Scale (Vogel et al. in Journal of Counseling Psychiatry, 56, 301–308, 2009), the Self-Stigma of Seeking Help Scale (Vogel et al. in Journal of Counseling Psychology, 53, 325–337, 2006), the Intention to Seek Counselling Inventory (Cash et al. in Journal of Counseling Psychology, 6, 111–112, 1975), and the Attitudes Toward Seeking Professional Psychological Help Scale-Short Form (Fischer and Turner in Journal of Consulting and Clinical Psychology, 1, 79–90, 1970). Results from multiple regression analyses indicated that there was no relation between Afrocentric spirituality and help-seeking attitudes or self-stigma about seeking counselling. However, there was a positive correlation between Afrocentric spirituality and other-perceived stigma, demonstrating that increased Afrocentric spirituality predicted increased perceived stigma from others about seeking counselling services. Contrary to expectations, there was a positive correlation between Afrocentric spirituality and intentions to seek counselling. Implications for counselling practice and theory are presented. 相似文献

There are multiple routes to becoming a special educator in Norway. In recent years, bachelor's degree programmes have offered an alternative to the traditional path in which special education coursework is taken as a part of teacher education. The purpose of this study was to investigate whether these different programmes produce different understandings of the special education profession and its core concepts. We surveyed 27 bachelor students and 36 teacher education students using open-ended questions concerning their future goals and expectations and the concepts of ‘inclusion,’ ‘learning disability,’ and ‘special educator’. Teacher education students were more likely to: (a) view inclusion from a broad perspective, emphasizing a sense of belonging and community, (b) define the concept of learning disability from a categorical perspective, and (c) perceive special educators as essentially ‘expert’ teachers for children with special needs. Bachelor’s degree students also emphasized special educators’ role in supporting individuals with special needs, yet were more likely to apply a relational perspective when describing the concept of learning disability. 相似文献
