This article presents early results of a research project designed to further our understanding of how to ensure that small scholar‐led journals can survive and thrive in a global open access knowledge commons. This phase of the research focuses on generation of ideas through interviews and focus groups with 15 participants involved in producing small scholar‐led journals that either are or would like to become open access. Although a couple of journals reported that they could survive in an open access future based on existing resources, most were concerned about survival and none expressed confidence that they could thrive in an open‐access future. These journals are far more diverse than one might imagine. Comparing the costs of article production from one journal with another might not make sense. A number of avenues for further research are discussed. 相似文献

Digital repositories require good metadata, created according to community-based principles that include provisions for interoperability. When metadata is of high quality, digital objects become sharable and metadata can be harvested and reused outside of the local system. A sample of U.S.-based repository administrators from the OpenDOAR initiative were surveyed to understand aspects of the quality and creation of their metadata, and how their metadata could improve. Most respondents (65%) thought their metadata was of average quality; none thought their metadata was high quality or poor quality. The discussion argues that increased strategic staffing will alleviate many perceived issues with metadata quality. 相似文献

Patterns of technology ownership and usage, as well as skills with and preferences for various technologies, affect the college experience (Educause 2012). Students at a commuter campus of a large Midwestern public university were surveyed about technology and the learning process: 94% of the respondents believed that technology had the potential to benefit learning and 85% thought it was central to their academic success. Students credited technology-enhanced courses with increased and more effective communication with instructors, the ability to better manage course activities and expanded opportunities for practice and reinforcement. Students’ prior experiences with a course management system affected their perceptions of the role of technology and their subsequent beliefs about the benefits of its use in their university courses. Implications for administrators who make decisions about faculty development, student retention and funding for technology-enhanced course offerings are discussed. 相似文献

The current study examines the association between parental support and adolescent sleep under varying levels of family stress. Participants included 316 adolescents (Mage = 16.40 years, 43% male) and their parents (Mage = 45.67 years, 91% mothers) from diverse ethnic backgrounds. Both adolescents and parents completed questionnaires and adolescents wore wrist actigraphs and completed self‐reports on their sleep for 7 consecutive days. Results indicated that under contexts of family stress, more parental support was linked to longer sleep duration, less sleep variability, and less time spent awake during the night. Findings suggest that under contexts of family stress, cohesive family relationships may provide a sense of stability and security that is necessary for healthful sleep. 相似文献

This paper reports on efforts aimed toward the development of more effective procedures for identifying mothers who are at elevated risk for problems in parenting. We present data from two independent samples of known maladaptors and corresponding comparison mothers and report on our attempts to cross-validate a promising screening instrument composed of items that index social support and parenting attitudes. The resultant 20-item scale correctly identified over 90% of maladaptive and comparison mothers. When this scale was cross-validated on a second independent sample of maladaptors and comparison mothers, it was again almost 90% accurate. Issues concerning the field application of this promising instrument are discussed and its possible limitations are considered. 相似文献

Selective universities regularly employ policies that favor children of alumni (known as legacies) in undergraduate admissions. Since alumni from selective colleges and universities historically have been disproportionately white, admissions policies that favor legacies have disproportionately benefited white students. For this reason, legacy policies lead to additional costs in terms of reductions in racial diversity. As larger numbers of minority students graduate from colleges and universities and have children, however, the potential pool of legacy applicants will change markedly in racial composition. This analysis begins with a review of the history and objectives of the preference for children of alumni in undergraduate admissions. We then consider the specific case of the University of Virginia and employ demographic techniques to predict the racial composition of the pool of potential legacy applicants to the university. Significant changes in the racial composition of classes that graduated from the University of Virginia from the late 1960s through the 1970s foreshadow similar changes in the characteristics of alumni children maturing through the next two decades. 相似文献

Efforts to encourage ‘interactive practice’ in the National Literacy (NLS) and Numeracy (NNS) Strategies in the UK, have led to an emphasis on teacher questions. Recent research into classroom interactions, however, indicate that the pattern of interaction remains largely unchanged since the introduction of these strategies in terms of the type and amount of questions teachers are asking, and the opportunities for extended pupil participation. This article uses evidence gathered from a large‐scale research project examining classroom interactions during literacy and numeracy lessons, and the researchers' critical reflections upon this process, to examine conceptions of interactive pedagogy. It is argued that in order to ‘open’ classroom interaction, emphasis should be less on the questions teachers ask, and more on the manner with which teachers react to pupils' responses to questions. Episodes of classroom interaction from video recorded literacy and numeracy lessons taken as part of the study are used to support this argument. They present evidence of teacher behaviours in reaction to pupils' responses which succeed in facilitating a more interactive learning environment. The implication that such behaviour will contribute towards a model of effective interactive practice is also discussed. 相似文献

Using two states’ grades 3 through 8 state assessment databases, this study documents the extent to which students were assigned testing accommodations for ELA or mathematics in only one of two consecutive years. The percentage of students with disabilities who were assigned accommodations in the current year only or in the prior year only in a given grade statewide was not trivial, sometimes exceeding 25%. The relationship between inconsistent assignment to any accommodations and both students’ prior proficiency level and aggregate growth is also documented. Group differences were observed at the state level. No practical differences were observed when covariates for inconsistent assignment were included in school value-added models, but very few schools had a substantial proportion of students with disabilities assigned accommodations inconsistently in a given grade. Implications for research and practice are discussed. 相似文献

RESEARCH FINDINGS: The purpose of this study was to examine the relations of children's effortful control and quality of relationships with teachers to school attitudes longitudinally in an ethnically diverse and economically disadvantaged sample. Data were collected as part of a larger intervention project during mid-fall, winter, and late spring (ns = 823, 722, and 758, respectively) for 2 cohorts of 3- to 5-year-olds (collected during 2 different school years). Children's effortful control was assessed in the fall with parents' and teachers' reports and 2 behavioral measures. Teacher-child relationship quality was assessed mid-year with teachers' reports of closeness and conflict. Attitudes toward school were assessed in late spring using teachers' and students' reports of school avoidance and liking. Effortful control, in general, was positively correlated with teacher-child closeness and school liking and negatively correlated with conflict and school avoidance. Using structural equation modeling and controlling for sex and ethnicity, we found that effortful control was positively related to teacher-child relationship quality, which in turn was positively related to school attitudes. Furthermore, the relation of effortful control to school attitudes was mediated by teacher-child relationship quality. PRACTICE OR POLICY: Results provide evidence for the importance of relational processes that take place within the classroom context and have implications for teachers and clinicians working to increase school success in ethnic minority and low-income children. 相似文献
