Specific and general information sharing among competing academic researchers     

Carolin Haeussler  Lin Jiang  Jerry Thursby  Marie Thursby 《Research Policy》2014

We examine information sharing among academics during the research process and show it is context dependent because of differences in trade-offs. When researchers respond to specific requests for information or materials, potential future reciprocity is weighed against the current loss of competitiveness, while general sharing intermediate results in an open forum is driven by the need for feedback versus potential misappropriation. We formally model these trade-offs and empirically test for differences using a survey of German and UK bio-scientists. Increased competition has a negative impact on sharing in both contexts. But career stage has an effect only on specific sharing with untenured faculty less likely to share. Further, scientists in larger teams are more likely to share specifically, but less likely to share generally. The importance of patents for one's reputation reduces sharing in both contexts, but the effect is greater for general information sharing.  相似文献   

The IFLA Trend Report: Looking Beyond the Walls in Library Planning     

Lynne Marie Rudasill 《图书馆管理杂志》2015,55(2):153-164

Strategic planning requires us to stop and take a closer look at our organizations and consider the impact that changes in the profession are causing, influenced by the society around us. These considerations lead us past our library walls, past our institutional walls and into a more speculative world of changes in the technological society. Scholars and pundits have provided us with many scenarios for the future, including a world of solely electronic resources and hyper-connected users. But how closely does this match reality and what are the trends in our larger society that will affect how we work in the future. This article provides an overview of several reports on the students and technologies that we work with and closely explores the IFLA Trend Report. The report was developed after discussions with individuals representing many non-academic, non-library organizations and provides us with a view of the larger trends forecast for the information society. The report is envisioned as a living document that invites further comment and wider distribution to the library world and beyond.  相似文献   

Communicating aims and learning goals in physical education: part of a subject for learning?     

Karin Redelius  Mikael Quennerstedt  Marie Öhman 《Sport, Education and Society》2015,20(5):641-655

Based on a socio-cultural perspective on learning, the aim of this article is to examine how aims and learning goals are communicated in physical education (PE) practice. A special focus is on scrutinising how teaching practices are framed in terms of whether and how the aims and learning goals are made explicit or not to students. The aim is also to relate these kinds of communications to different movement cultures. The result shows that many of the students taking part in the study do not understand what they are supposed to learn in PE. However, if the goals are well articulated by teachers, the students are more likely to both understand and be aware of the learning outcomes and what to learn in PE. The opposite is also true. If the goals and objectives are not clarified, students find it difficult to state the learning objectives and know what they are supposed to learn.  相似文献   

Defining Peer-to-peer Learning – from an Old ‘Art of Practice’ to a New Mode of Forest Owner Extension?     

Katri Hamunen  Marie Appelstrand  Teppo Hujala  Mikko Kurttila  Nadarajah Sriskandarajah  Lelde Vilkriste 《The Journal of Agricultural Education and Extension》2015,21(4):293-307

Purpose: This paper explores the concept of peer-to-peer learning (P2PL) in the context of North-European small-scale forest owners. The aim is to develop a framework for initiating new and evaluating already existing forest owners' P2PL communities.

Design: Previous studies of peer-learning are used to determine and justify eight dimensions for forest owners' P2PL. To demonstrate and test the operability of the dimensions, two potential forest owners' peer-learning cases are described. The Finnish case focuses on forest owner clubs based on group interview data and the coordinator's interview, and in the Swedish case an ongoing study circle was observed and its participants interviewed.

Findings: The eight P2PL dimensions defined are: initiation, reinforcement, content profile, participant profile, schedule, role of professionals, responsibility and role continuity. Of the described cases, Finnish forest owner clubs rely heavily on the expertise of the invited forest professionals, while owners themselves have a stronger role in Swedish study circles.

Practical Implications: The two studied cases and the fictional example demonstrate how the framework defined can be used when assessing real life cases. The framework allows describing consistently P2PL, when designing new practices or implementing step-by-step changes to modify existing P2PL practices.

Value: The framework gives new insights into the research of forest owner extension, which has had an increasing interest towards P2PL approach, but where its conceptualisation has remained vague. However, since the domain of the study is novel, further research with various case examples is needed to develop both the theoretical framework and real life practices.  相似文献   

Outcomes of structured teaching for children on the autism spectrum: does the research evidence neglect the bigger picture?          下载免费PDF全文

Marie Howley 《Journal of Research in Special Educational Needs》2015,15(2):106-119

The adoption of ‘structured teaching’ is evident in educational settings worldwide and has fast become one of the key ‘tools’ in autism education. As calls for evidence‐based practice have increased, research evidence has grown to interrogate the effectiveness of structured teaching components. Previous systematic literature reviews of the research evidence suggest that structured teaching has positive effects upon problem behaviours and also increases engagement and independent task organisation. This literature review builds upon previous reviews in order to explore the effects of structured teaching upon behaviour and learning, asking what the research evidence actually measures in relation to these two concepts. Gaps in the research evidence are identified, and discussion focuses upon the need for research which investigates the role of structured teaching components in meaningful learning, the need for greater attention to evaluate social validity of the approach which takes into account those who implement and indeed those who receive the intervention and finally the need for research to analyse the effects of structured teaching upon alternative outcomes of ‘well‐being’ and ‘quality of life’.  相似文献   

Taking Stock of Two Decades of Attachment Transmission Gap: Broadening the Assessment of Maternal Behavior     

Annie Bernier  Célia Matte‐Gagné  Marie‐Ève Bélanger  Natasha Whipple 《Child development》2014,85(5):1852-1865

This report aimed to investigate the capacity of maternal behaviors tailored to children's attachment and exploration systems to jointly explain the well‐known mother–child transmission of attachment. Four home visits were conducted between ages 7 months and 2 years with 130 mother–child dyads to assess maternal attachment state of mind, sensitivity, autonomy support, and mother–child attachment security. Results showed that together, maternal sensitivity and autonomy support fully accounted for the relation between maternal and child attachment, that they each accounted for a unique portion of this relation, and that the magnitude of these mediated pathways was equivalent. These results suggest that the attachment transmission gap can be narrowed by the use of a theory‐driven multidimensional approach to maternal behavior.  相似文献   

Local Observed‐Score Kernel Equating     

Marie Wiberg  Wim J. van der Linden  Alina A. von Davier 《Journal of Educational Measurement》2014,51(1):57-74

Three local observed‐score kernel equating methods that integrate methods from the local equating and kernel equating frameworks are proposed. The new methods were compared with their earlier counterparts with respect to such measures as bias—as defined by Lord's criterion of equity—and percent relative error. The local kernel item response theory observed‐score equating method, which can be used for any of the common equating designs, had a small amount of bias, a low percent relative error, and a relatively low kernel standard error of equating, even when the accuracy of the test was reduced. The local kernel equating methods for the nonequivalent groups with anchor test generally had low bias and were quite stable against changes in the accuracy or length of the anchor test. Although all proposed methods showed small percent relative errors, the local kernel equating methods for the nonequivalent groups with anchor test design had somewhat larger standard error of equating than their kernel method counterparts.  相似文献   

A Model of Academic Self-Concept for High School Hispanic Students in New York     

Flor R. Calero  Christopher Dalley  Nicole Fernandez  Tania Marie Davenport-Dalley  Stephanie L. Tatum 《Journal of Latinos & Education》2014,13(1):33-43

This study examined how Hispanic students’ academic self-concept influences the independent variables of family academic expectations, peer relationships, schoolwork, and student–teacher relationships. A survey was administered to 222 ninth-grade students in Long Island, New York, 99 of whom self-identified as Hispanic. A structural equation model analyzed the influence of the independent variables on the dependent variable, academic self-concept. A multiple regression analysis indicated that peer relationships, family academic expectations, and schoolwork were significant predictors of students’ academic self-concept. Peer relationships was a modifying variable on students’ academic self-concept.  相似文献   

Fabricating and prefabricating language: troubling trends in libraries     

Anne Marie Candido   《The Journal of Academic Librarianship》1999,25(6):151

Librarians are succumbing to the influence of the easy-to-adopt, prefab, impersonal, ugly, and often impenetrable jargon borrowed from business and computer technology. Thus, they are in danger of beginning to think of libraries as businesses that provide primarily electronic information and facts rather than materials to support humanistic knowledge and insight.  相似文献   

Towards a general modeling framework of resource competition in cognitive development     

Jill de Ron  Marie Deserno  Donald Robinaugh  Denny Borsboom  Han L. J. van der Maas 《Child development》2023,94(6):1432-1453

The current paper presents an integrated formal model of typical and atypical development based on the mechanisms of mutualism and resource competition. The mutualistic network model is extended with the dynamics of competition for limited resources, such as time and environmental factors. The proposed model generates patterns that resemble established phenomena in cognitive development: the positive manifold, developmental phases, developmental delays and lack of early indicators in atypical development, developmental regression, and “quasi-autism” caused by extreme environmental deprivation. The presented modeling framework fits a general movement towards formal theory construction in psychology. The model is easy to replicate and develop further, and we offer several avenues for future work.  相似文献
