Following landmark legislation passed more than 20 years ago, university–industry relationships have now become central to understanding the changing role of research universities in American Society. The paper analyzes the development of university–industry partnerships during the 1990s. Past studies have used a broad array of measures of ties and a variety of research methodologies, but they have shared a focus on top collaborators or on samples of universities skewed toward the top. However, findings based on top collaborators may not be valid for other universities. Universities involved in mid- to low-levels of collaboration are qualitatively different in many ways from the more extensively studied set of top collaborators, suggesting that characteristics affecting university–industry ties may not be the same for these institutions. The paper shifts the focus away from top collaborators to this sizable and less studied majority. In general, we find that the same characteristics predicting high levels of involvement for the sample as a whole also predict high levels of involvement for the sub-sample of mid- and low-level collaborators. However, We find some particular characteristics of these institutions, such as land grant status, are also associated with stronger ties to industry, and that some characteristics of 25 top institutions do not predict the level of involvement of these lower-level collaborators. We will discuss whether the licensing of new technology is likely ever to become an important source of net revenues for current middle and low-level collaborators. Our findings raise doubts about whether many universities below the top 25 will earn substantial net revenues from licensing, though they do not dispute the potential service value of these ties. The study is based on examination of a wide range of potential influences on university–industry collaboration for institutions that are not currently among the most heavily involved in partnerships. These include status, other institutional characteristics (such as size and control), investment in science and engineering, and characteristics of offices or technology transfer. 相似文献

Although many studies have explored shared book reading between preschoolers and their families, very few have examined this practice within a large, nationally representative sample. Using the ECLS-B dataset, this study investigated shared reading among nearly 700 families of diverse ethnic, linguistic, and socioeconomic backgrounds. Coding of families’ book-related discussion focused on the variety of types of talk that parents used during reading. Results showed that parents focused primarily on the meaning of the story, with little attention to the code of the text. The range of talk techniques that parents used was largely independent of background factors such as child gender, ethnicity, or age, as well as family home language. A wider variety of meaning-related remarks by parents was linked to more advanced language skills among preschoolers. Findings provide a portrait of the nature of shared book reading discussion among American families, a profile of the background factors that are linked to this talk, and a precise account of the unique contributions of this talk to key emergent language and literacy competencies. 相似文献

Preschoolers’ (n?=?32) attention to print and pictures was documented during an electronic storybook reading session. Children (M?=?51.06 months; SD?=?7.34 months) looked at a 12-page book that contained three types of pages, each of which was presented four times over the course of the book: (1) silent presentation of print, (2) print that was read aloud, and (3) print that was both read aloud and highlighted. Our research objectives were to analyze whether the way in which print was presented related to the ways in which children attended to print and pictures during the reading session. Gaze fixation duration to print and pictures was assessed using a Tobii X2-60 portable eye tracking unit, which captured corneal reflection data for each child. Children’s total fixation duration to print was greatest when print was read aloud and highlighted as compared to when it was presented silently or read aloud. In addition, children looked at print more when it was displayed silently than when the computer read the story to children, although this difference was much smaller in magnitude. Children attended to pictures more than print across pages, but this difference was most notable when the story was read aloud. Results demonstrate the potential utility of nonverbal print referencing strategies during book reading. 相似文献

This study examined low-income, Spanish-speaking, immigrant Latina mothers' book sharing behaviors in relation to their children's vocabulary. Participants were 47 3-year-old children and their mothers. We addressed two research questions: (a) What interactive behaviors are evident when low-income immigrant Latina mothers and their 3-year-old children look at books together? (b) For these children and their mothers, which book-sharing behaviors are related to children's expressive language? Overall, our results indicated that mothers were involved in several kinds of interactions with the books. They enhanced their children's attention to the printed text, promoted interaction or conversation with their children about what was in the books, and somewhat less often, used more complex literacy strategies. Mothers who did these things most had children with the largest vocabularies even when mothers' vocabulary was taken into account. Implications for designing interventions for similar families are discussed. 相似文献

A mixed-methods study was undertaken with 118 biology students in two urban high schools. A Student-Centered Adaptable Learning Environment (SCALE) was created to improve engagement from affective and cognitive perspectives using choice, creativity and technological allowances. Results demonstrated that fast and slow learners are generally separated by about 30 min in terms of inputting speeds, but can be as much as 65 min apart from one another. Given that traditional classrooms afford students only 45 min in which to learn, static time could have become a source of inequity in public schools. SCALE optimally allowed for the dynamic use of time in constrained periods, therefore reducing and even eliminating any negative relationships between speed of learning and resultant achievement gains in the block setting. Especially benefitting from their ability to maneuver were the slowest learners, who showed the largest achievement improvements in either time interval amongst ability groupings. As learning speed can be the most critical contributing component of resultant educational outcomes, providing students the ability to use time dynamically should be considered as a feasible solution to helping teachers reestablish equity in mixed-ability classrooms in public schools. 相似文献

Barbara Albers Hill markets the book, Breaking Through: Using Educational Technology for Children with Special Needs, as a tool providing assistance with use of educational technology as it relates to children with special needs. The mention of specific special needs, such as children with Autism and Attention Deficit Hyperactivity Disorder (ADHD), leads readers to believe the book will provide detailed information on how educational technology will assist a child according to each specific need. Hill organizes the book in two parts. The first part provides an overview of tablet technology and how to use it to enhance learning for children with special needs. Part two of the book provides the reader with information that will assist a consumer with purchasing the right tablet for the special need. Upon review of the content, the book is less about detail and more about a shopping guide for the consumer as to the best tablet to select for children with special needs. 相似文献

OBJECTIVES: To assess the impact of home visiting in preventing child abuse and neglect in the first 3 years of life in families identified as at-risk of child abuse through population-based screening at the child's birth. METHODS: This experimental study focused on Hawaii Healthy Start Program (HSP) sites operated by three community-based agencies. From 11/94 to 12/95, 643 families were enrolled and randomly assigned to intervention and control groups. Child abuse and neglect were measured by observed and self-reported parenting behaviors, all hospitalizations for trauma and for conditions where hospitalization might have been avoided with adequate preventive care, maternal relinquishment of her role as primary caregiver, and substantiated CPS reports. Data were collected through annual maternal interviews (88% follow-up each year of all families with baseline interviews); observation of the home environment; and review of CPS, HSP, and pediatric medical records. RESULTS: HSP records rarely noted home visitor concern about possible abuse. The HSP and control groups were similar on most measures of maltreatment. HSP group mothers were less likely to use common corporal/verbal punishment (AOR=.59, p=.01) but this was attributable to one agency's reduction in threatening to spank the child. HSP group mothers reported less neglectful behavior (AOR=.72, .02), related to a trend toward decreased maternal preoccupation with problems and to improved access to medical care for intervention families at one agency. CONCLUSIONS: The program did not prevent child abuse or promote use of nonviolent discipline; it had a modest impact in preventing neglect. Possible targets for improved effectiveness include the program's implementation system and model. 相似文献

Evidence from large-scale studies of primary and secondary students’ technology practices at school over the last decade show disparities in student practices and suggest that schools need to do more to cater for all students. Research that explores the influence of social and cultural factors may be useful for understanding such inequality in student practice. Bourdieu’s theory of practice [(1977). Outline of a Theory of Practice. London: Cambridge University Press] is proposed as an example of a sociological theory that can be adopted in educational technology research to move towards understanding the wider complexities of technology practice. To encourage discourse and application of Bourdieu’s sociology in the field of educational technology research, this paper provides an introduction to the theory, a review of its application in research of primary and secondary students’ technology practice and relevant conceptual work. The paper presents a conceptual framework based on Bourdieu’s theory that has been developed through two recent studies, and review of empirical and conceptual works and invites its application in future research so that it can be critiqued and further developed. 相似文献

The role of prior social experience in maleBetta agonistic behavior was investigated in two experiments. Fish were either paired with an opponent until dominance was established naturally (Experiment 1) or given prior combat experience with a known aggressive or nonaggressive opponent (Experiment 2). The effects of prior social experience were then observed both in additional paired encounters and in some noncombat agonistic situations. The paired-encounter data indicate thatBetta attack aggressive opponents more than nonaggressive ones and rarely attack opponents once they have submitted. In contrast to attacking, these fish do not show a significant decrease in displays once their opponent has submitted, nor do they display differentially to aggressive and nonaggressive opponents. The noncombat agonistic-situation data indicate that prior social experience affects both the preference of fish for viewing other conspecifics and the waning of display behaviors. These results suggest that submissive and nonaggressive behaviors can inhibit attacks but not displays byBetta, and they emphasize the necessity of controlling for prior social experience when studying aggressive behavior. 相似文献

This article reports on research funded by the Australian Research Council to investigate school responses to gender equity. It addresses the efforts of a disadvantaged school to tackle what they perceived to be gender inequalities, but in the process of constructing a top‐set and bottom‐set/stream class they are developing new forms of old inequalities and new forms of inequalities. This research indicates that despite popular assertions that girls' education has become the priority of schools and education systems, girls are being further disadvantaged through attempts to implement market strategies coupled with gender reform agendas grounded in liberal notions of equity and relying on unsophisticated notions of affirmative action. In addition, this study highlights the extent to which a media‐driven debate about boys' education has influenced the constitution of boys as the ‘new disadvantaged’ with the capacity to determine the nature of gender reform agendas and programmes in schools. 相似文献
