This paper provides a systematic examination of the use of a Grand Innovation Prize (GIP) in action – the Progressive Automotive Insurance X PRIZE – a $10 million prize for a highly efficient vehicle. Following a mechanism design approach we define three key dimensions for GIP evaluation: objectives, design, and performance, where prize design includes ex ante specifications, ex ante incentives, qualification rules, and award governance. Within this framework we compare observations of GIPs from three domains – empirical reality, theory, and policy – to better understand their function as an incentive mechanism for encouraging new solutions to large-scale social challenges. Combining data from direct observation, personal interviews, and surveys, together with analysis of extant theory and policy documents on GIPs, our results highlight three points of divergence: first, over the complexity of defining prize specifications; secondly, over the nature and role of incentives, particularly patents; thirdly, the overlooked challenges associated with prize governance. Our approach identifies a clear roadmap for future theory and policy around GIPs. 相似文献

OBJECTIVE: Women with histories of childhood maltreatment (CM) have higher rates of physical health problems and greater medical utilization compared to women without abuse histories. This study examined whether current post-traumatic stress disorder (PTSD) symptoms mediate the relationship between CM and indicators of physical health and medical utilization in female veterans. METHOD: Respondents were 221 female veterans (56% of the potential sample), who received medical care from the San Diego VA Healthcare System during a 12-month period. Respondents provided self-report information about CM, PTSD symptoms, use of pain medication, and physical symptoms and functioning. Additional information about medical utilization was extracted from respondents' medical charts. Regression-based models were conducted to test whether PTSD symptoms mediate the relationships between CM and physical symptoms and between CM and medical utilization. RESULTS: Emotional abuse was associated with poorer role-physical functioning, increased bodily pain and greater odds of using pain medication in the past 6 months. Physical abuse was associated with poorer general health. Contrary to prediction, emotional neglect was associated with better role-physical functioning, and CM was not associated with increased healthcare utilization. PTSD was shown to mediate the relationship between emotional and physical abuse and health outcomes. CONCLUSIONS: PTSD, or psychopathology more generally, appears to be an important factor in the negative health impact of CM. Given that several empirically supported interventions are available for PTSD, there may be physical health benefits in early identification and treatment of psychopathology related to CM. 相似文献

Abstract This article reports on research analysing how primary initial teacher educators define and participate in research activities. A representative sample of teacher educators in one institution in the UK were interviewed in depth to identify individuals' perceptions of the place of research in their work. All the interviewees saw their most important role as teaching and supporting students. In all cases, research was seen as a low priority. Engagement in research was seen as moving away from the practical, school and student centred world of primary initial teacher education towards a more conventionally ‘academic’ world. The established researchers within the teacher education community were seen as a privileged elite. Two clusters of factors which influence these perceptions are defined as: firstly, the effects of the changing nature of the institution and internal structures it has generated in response to national changes; and secondly, the ways in which the interviewees define their work its conditions and its underlying values. These factors and the tensions they cause are explored in relation to the pressures placed on the teacher education communities by the 1996 Research Assessment Exercise and the development of increased partnerships with schools. 相似文献

ABSTRACTThis paper investigates community college transfer success by exploring the relationship between individual and institutional-level characteristics at students’ two- and four-year institutions. Using statewide administrative data from North Carolina, this study employs a cross-classified multilevel model to investigate the impact that a student’s community college and four-year transfer institution have on post-transfer success. Our findings offer important and compelling insights into the relationship between transfer students, the community college they attended, the four-year transfer institution, and educational outcomes. While individual effects were small, we find several institutional factors associated with student success. Attendance at a large community college or having a public university in the same county as their community college is positively associated with student success, whereas size of the university is negatively related to grades during the first year and persistence to the second year. While the four-year institution’s selectivity is negatively related to many of our outcomes, transferring to a Historically Black College or University is positively associated with GPA, college persistence, and degree completion. 相似文献

This study examined associations among early adversity, diurnal cortisol, child sex, and caregiver sensitivity at age 6 months in relation to wheezing in children (47% male) followed to 30 months. Analyses included 676 mother-child dyads, 393 of whom completed an observational caregiver sensitivity measure. Participants were primarily ethnic minorities (42.7% Black, 25.4% Hispanic); 22.1% of children had ≥ 1 wheezing episode. Higher adversity was associated with increased wheeze frequency and blunted diurnal cortisol slope. The indirect effect of adversity on wheezing through cortisol slope was significant for females, but not males. Higher caregiver sensitivity was protective against wheezing for males, but not females, with high cortisol. Findings suggest complex associations among adversity, cortisol, child sex, and caregiver sensitivity in predicting wheezing. 相似文献

Despite extensive research supporting educational acceleration for students with high academic ability, some psychologists, counselors, and educators express concerns about accelerative interventions. Such concerns often hinge on uncertainty about social acceptance, even in inclusive education settings. Research on acceleration has consistently shown benefits for students with high ability; however, there is a lack of research about grade‐based acceleration in inclusive schools. This study engaged two groups of students in group concept mapping processes to examine how they conceptualized beliefs about grade‐based acceleration in inclusive schools. First, 26 students in inclusive classes generated beliefs about grade‐based acceleration. Then they, and a group of 14 students with high ability, structured the data by sorting and rating a synthesized list of the generated beliefs. We analyzed the sorted data using multidimensional scaling and hierarchical cluster analysis. The resultant cluster maps revealed some differences and some similarities in the ways that the two groups of students conceptualized beliefs about educational acceleration. Practical implications are discussed. 相似文献

Dyslexic and a normal group consisting of 104 children each were matched with reference to age, income, intelligence, and sex. Specific personality dimensions including self-concept, achievement motivation, general manifest anxiety, test anxiety, and behavior deviance were measured. Dyslexic children showed poorer adjustment in all areas of personality. Comparison of results within the dyslexic group showed that children who are successful in remedial training show better emotional adjustments than unsuccessful dyslexic children. A stepwise multiple regression analysis employing personality variables and overall success in remedial language training was computed. Classroom behavior and self concept were found to correlate with success and yielded a multiple correlation of .544. Results are discussed with reference to remediation and treatment. 相似文献

OBJECTIVE: The goal was to develop a retrospective inventory of parental threatening behavior to facilitate a better understanding of such behavior's role in the etiology of psychological distress. METHOD: Inventory items were developed based on theory and 135 students' responses to a question eliciting examples of threatening parental behavior. Following item development, two additional student samples (n = 200 and n = 603) completed batteries of self-report measures. Responses were used to eliminate unstable or redundant items from the inventory and to examine the inventory's psychometric properties. RESULTS: Factor analysis of the inventory revealed three factors, accounting for 66.2% of variance; this factor structure is compatible with theory, and consistent across maternal behavior scores, paternal behavior scores, and combined maternal and paternal scores. Cronbach's coefficient alphas indicated acceptable internal consistency; Pearson correlation coefficients indicated acceptable 4-week test-retest reliability. Moderate intercorrelations with two retrospective measures of childhood experiences suggested construct validity. Regression analyses demonstrated the ability of the inventory to predict both anxious and depressive symptomatology and lifetime symptoms of anxiety and depressive disorder. Normative data on combined parent scores, maternal scores, and paternal scores are also presented. CONCLUSIONS: Initial psychometric testing of the Parent Threat Inventory (PTI) suggests it is a reliable and valid tool for investigating the developmental antecedents of adult psychological distress. Further research should focus on addressing two limitations: (1) lack of normative and psychometric data on men and women suffering from clinical disorders, and (2) lack of validation by parental reporting. 相似文献
