This invaluable little product is a freely available “manual for streaming audio on the web”. The context of its origin is the growing use in India of internet‐based community radio, and of the use of that for educational and training purposes. Tested in a CoL workshop, the manual provides a wealth of generally accessible advice and guidance for setting up such radio stations / web channels and the dvd contains the manual and the (free and open source) software needed. If the concept of this package is likely to be of interest, get a copy—you'll find it fascinating! Eric Deeson  相似文献   

Assessing the impact of the funding environment on researchers’ risk aversion: the use of citation statistics     

Frank A. Zoller  Eric Zimmerling  Roman Boutellier 《Higher Education》2014,68(3):333-345

The funding environment has a profound impact on researchers’ behavior. In particular, it influences their freedom and readiness to conduct research ventures with highly uncertain outcomes. In this conceptual paper, we propose a concise new methodology to evaluate researchers’ risk aversion based on citation statistics. The derived single-number criterion P_R is sensitive to the ratio of high impact versus average impact work, based on citation counts. We demonstrate the usefulness of P_R on a micro and meso level in the field of chemistry. P_R is a potentially valuable tool for managers in higher education, to control for the impact of their funding instruments. The conducted testing may, in addition, contribute to the literature stream dealing with the effects of peer review in the allocation of research funding. Our results support the view that peer review fosters mainstream research. However, faculties with the highest percentages of third-party funding may find ways to avoid the restrictive effects. We also find evidence that permanent positions back risky research endeavors.  相似文献   

Students’ images of two-variable functions and their graphs     

Eric Weber  Patrick W. Thompson 《Educational Studies in Mathematics》2014,87(1):67-85

This paper presents a conceptual analysis for students’ images of graphs and their extension to graphs of two-variable functions. We use the conceptual analysis, based on quantitative and covariational reasoning, to construct a hypothetical learning trajectory (HLT) for how students might generalize their understanding of graphs of one-variable functions to graphs of two-variable functions. To evaluate the viability of this learning trajectory, we use data from two teaching experiments based on tasks intended to support development of the schemes in the HLT. We focus on the schemes that two students developed in these teaching experiments and discuss their relationship to the original HLT. We close by considering the role of covariational reasoning in generalization, consider other ways in which students might come to conceptualize graphs of two-variable functions, and discuss implications for instruction.  相似文献   

Word reading and word spelling in French adult literacy students: the relationship with oral language skills     

Elsa Eme  Eric Lambert  Denis Alamargot 《Journal of Research in Reading》2014,37(3):268-296

We analysed word reading and spelling in French adults with low levels of literacy (A‐IL). As well as examining phonological and lexical processes, we explored the relationship between literacy and oral language skills. Fifty‐two adult literacy students were compared with reading level‐matched pupils in Years 1–3 of primary school on reading tasks (pseudoword reading, word reading, text comprehension), spelling tasks (pseudoword spelling, text dictation) and oral language tasks. A‐IL scored the same as children on word reading and spelling but less well on pseudoword reading and spelling. They also produced fewer phonologically acceptable errors in the dictation. Regarding oral language skills, as a group A‐IL encountered greater difficulty in phonology than in morphosyntax and semantics, and correlations revealed strong relationships between literacy levels and oral skills, particularly in the domain of phonology. Within their group, however, A‐IL displayed several distinct language profiles. These could reflect different risk factors leading to functional illiteracy and are discussed regarding the cognitive and environmental causes of impaired reading acquisition.  相似文献   

Identifying Teachers Attending Professional Development by Their Stages of Concern: Exploring Attitudes and Emotions     

Eric Christesen  Jeannine Turner 《The Teacher Educator》2014,49(4):232-246

The purpose of this study was to use the Stages of Concerns (SoC) framework established by Hall and Loucks as a way to usefully identify types of teachers. Teachers who participated in the study were attending a professional development program called Great Expectations (GE). A modified version of the SoC questionnaire was used, so an exploratory factor analysis (EFA) of the modified questionnaire was conducted and identified a five factor structure. Using these five factors, a latent profile analysis was conducted to identify teachers. Three types of teachers emerged: enthusiastic teachers, teachers who were uninterested in the GE program, and teachers who were interested in the program but still had trepidations. These three groups were then compared on their emotions prior to the beginning of the GE program and their experience with GE. The quantitative results from this study are compared to qualitative results from previous research on teachers' SoC.  相似文献   

The changing experiences of bisexual male adolescents     

Max Morris  Eric Anderson 《Gender and education》2014,26(4):397-413

Drawing on in-depth interviews with 15 openly bisexual male youth from sixth forms across the UK, this article documents positive experiences of bisexual male youth in school: participants had positive coming out experiences and did not encounter significant discrimination or harassment because of their sexual identity. Participants attribute this to the inclusive environments of their schools and local cultures. Examining the narratives of two participants who had negative experiences, this article also highlights continued issues for bisexual youth in schools. It thus advances our understanding of contemporary bisexual lives in educational institutions, and contributes to debates about whether sixth forms are more inclusive spaces than secondary schools for bisexuals.  相似文献

Functional fragmentation in city hall and Twitter communication during the COVID-19 Pandemic: Evidence from Atlanta,San Francisco,and Washington,DC     

Eric S. Zeemering 《Government Information Quarterly》2021,38(1):101539

The organization of city government into specialized departments allows cities to accomplish an array of service delivery tasks. Government reformers argue this fragmentation creates coordination challenges when problems spillover the lines of specialized agencies. Functional fragmentation also poses coordination challenges for government communication with the public through social media. The global SARS-CoV-2 pandemic and COVID-19 disease provide an opportunity to investigate the consequences of functional fragmentation in city government for social media communication about public health and pandemic response. A comparative case analysis of three cities using data from city agency Twitter accounts and key informant interviews demonstrates the consequences of fragmentation for internal coordination, as well as public outreach. The experiences of Atlanta, San Francisco, and Washington, DC in the early days of the pandemic provide pragmatic insights for city officials and illustrate the theoretical importance of giving attention to whole of government approaches to city social media communication.  相似文献   

User community vs. producer innovation development efficiency: A first empirical study     

Christoph Hienerth  Eric von Hippel  Morten Berg Jensen 《Research Policy》2014

In this paper we report upon a first empirical exploration of the relative efficiency of innovation development by product users vs. product producers. In a study of over 50 years of product innovation in the whitewater kayaking field, we find users in aggregate were approximately 3× more efficient at developing important kayaking product innovations than were producers in aggregate. We speculate that this result is driven by what we term “efficiencies of scope” in problem-solving. These can favor an aggregation of many user innovators, each spending a little, over fewer producer innovators benefitting from higher economies of scale in product development. We also note that the present study explores only one initial point on what is likely to be a complex efficiency landscape.  相似文献   

Do more hours in center-based care cause more externalizing problems? A cross-national replication study     

Catalina Rey-Guerra  Henrik D. Zachrisson  Eric Dearing  Daniel Berry  Susanne Kuger  Margaret R. Burchinal  Ane Nærde  Thomas van Huizen  Sylvana M. Côté 《Child development》2023,94(2):458-477

Whether high quantities of center-based care cause behavior problems is a controversial question. Studies using covariate adjustment for selection factors have detected relations between center care and behavior problems, but studies with stronger internal validity less often find such evidence. We examined whether within-child changes in hours in center-based care predicted changes in externalizing problems in toddlers and preschoolers (N = 10,105; 49% female; data collection 1993–2012) in seven studies, including from Germany, Netherlands, Norway, two from Canada and two from the U.S. Race/ethnicity data were only collected in the United States (57% and 80% White; 42% and 13% African-American; 1.2% and 5% Latinx). Meta-analyses showed no association (r = .00, p = .88) between hours in center-based care and externalizing problems.  相似文献
