Previous research finds that both Ph.D. program quality and relative dissertation advisor prominence are positively related to early-career publishing success. We provide insight into the relative importance of those factors by estimating early-career research productivity functions that: (1) allow relative dissertation advisor prominence to vary while holding Ph.D. program quality constant and (2) allow Ph.D. program quality to vary while holding relative dissertation advisor prominence constant. Results for a sample of 2983 economics Ph.D. recipients suggest that: (1) the estimated marginal effects of relative dissertation advisor prominence do not vary systematically within top Ph.D. programs and (2) students graduating from a program-switching advisor's higher-ranked program publish significantly more than those graduating from his or her lower-ranked program. Combined, these results might suggest that the observed correlation between dissertation advisor prominence and early-career publishing results more from students working with prominent advisors possessing the higher innate potential required to gain admission to top programs rather than strictly because they work with the more prominent advisor. 相似文献

This article looks at virtual mentoring programs through a lens of generational differences, technological preferences, and communication styles. Best practices are framed to address the need to prepare the incoming millennials to lead the workforce as baby boomers exit. After a review of the literature, ideas are culled to apply the theory to a virtual mentoring program. Special attention is paid the concept of virtual mentoring based on lack of collocation of modern teams. 相似文献

Beyond some contracted minimum, salaried workers’ hours are largely chosen at the worker's discretion and should respond to the strength of contract incentives. Accordingly, we consider the response of teacher hours to accountability and school choice laws introduced in US public schools over the past two decades. Total weekly hours of full-time teachers have risen steadily since 1983 by about an hour, and after-school instructional hours have increased 34 percent since 1987. Average hours and the rate of increase also vary widely across states. However, after accounting for a common time trend in hours, we find no association between the introduction of accountability legislation and the change in teacher hours. Education reforms are, however, associated with an increase in student test scores, presumably due to other types of changes in school and teacher behavior. 相似文献

Difficulty processing sensory information may impede progress in school for students with autism spectrum disorder (ASD). We explore the relationship between sensory processing and school performance in 26 high‐functioning youths with ASD and 26 controls (age 8–14) using measures of sensory, social, cognitive, and academic functioning. In the ASD group, bivariate Pearson correlations indicated a significant positive relationship between intelligence quotient (IQ) and the School Competence Scale (SCS) of the Child Behavior Checklist (CBCL), and a significant negative relationship between Dunn's Sensory Processing Framework and SCS scores. Final hierarchical multiple linear regression model accounting for SCS scores in ASD included IQ, ADHD symptoms, and sensory features. An interaction between increased sensory sensitivity with reduced sensory avoidance behaviors explained the greatest amount of variance in SCS, meaning school performance is lowest for children with greater hypersensitivity and fewer avoidance behaviors. Results indicate a strong impact of sensory processing on school performance in ASD. 相似文献

This article focuses on the development of decision‐making skills and environmental concern by 11‐ and 12‐year‐old students through computer‐based, scaffolded learning activities. The enacted activities provided necessary scientific information and allowed for the consideration of multiple aspects of the problem, the study of the effects of every possible solution and the formulation and balancing of criteria. The optimization strategy for decision making was adopted, because it allows for the development of compensatory thinking which is more relevant to actual situations of decision making. Twelve students participated in the pilot enactment of the proposed activities. Data collection relied on students’ reports and pre‐ and post‐ tests as well as a closed questionnaire designed to measure students’ environmental concern. The teaching intervention proved quite successful in enhancing the decision‐making skills of the participating children. Moreover, students’ performance on the environmental concern questionnaire correlated in interesting ways with the improvement of decision‐making skills. 相似文献

The rise of digital media labs and spaces for content creation in public libraries has been documented in the scholarly literature. However, fewer studies have investigated the outcomes of media literacy initiatives in community media centers (CMCs) and how they might inform similar programs and services in public libraries. This article reports findings from a study that used qualitative research to investigate the current goals and activities of CMCs across the United States. The findings show that the educational, social, and community benefits of these programs could be useful for public libraries to consider in developing or augmenting their own media literacy initiatives. 相似文献

Abstracts English: This study examined the effectiveness and efficiency of a three‐dimensional virtual reality simulation model designed to train kindergarten teachers in the understanding of kindergarten children's needs and perceptions. Statistical analysis of the data indicates that the kindergarten teachers who were trained through the virtual reality technology were significantly more understanding of children's needs and perceptions than those trained through the workshop method. Thus, in light of the results of the study, it is suggested that teacher trainers should favourably consider using virtual reality simulation models in the training of kindergarten teachers in order to maximize the effectiveness of the teacher‐training process. 相似文献

Innovation researchers have begun to look beyond how users develop tangible objects or product innovations and moved to investigate the existence and impact of intangible user-developed innovations in techniques and services in the household sector . In this paper, to incorporate technique and service innovations and other varieties of intangible innovations not yet described in the literature into an efficient and encompassing typology, we propose the new concept of intangible Behavioral Innovation as an overarching category that stands in contrast to tangible product innovation. Behavioral innovation is defined as consisting of one or a connected sequence of intangible problem-solving activities that provide a functionally novel benefit to its user developer relative to previous practice. We demonstrate in a pilot study using a relatively novel big data-gathering and semantic analysis approach that behavioral innovation exists and can be identified in user-generated content posted openly online in peer-to-peer discussion forums relating to household sector activities such as parenting. The preponderance (N = 138) of the 168 user innovations captured in our samples of discussion comments were intangible behavioral innovations, most of which were developed by women. The majority of behavioral innovations identified were diffused by their user developers in response to specific requests for help or advice from peers in their online community. Thus, incorporating the new concept of intangible behavioral innovation into studies of user innovation's scope and significance in the household sector can serve to clarify which users innovate in our communities of interest, what and how they innovate, why they are triggered to diffuse their innovations peer-to-peer, and how their innovative activities might impact social welfare. 相似文献
