The value of structured abstracts in information retrieval from MEDLINE     

Andrew Booth  Alan O&#x;Rourke 《Health information and libraries journal》1997,14(3):157-166

Objective: To determine whether information retrieval might be enhanced by making each component of a structured abstract a separately searchable field. Design: Parallel searches on records arranged so that each abstract could either be searched in its entirety or as a collection of structured fields. Subjects: Records about cardiovascular disease downloaded from MEDLINE and tested against clinical questions derived from a concurrent survey of CD-ROM use in three health science libraries. Intervention: The investigators identified terms used to structure abstracts on MEDLINE and imported the abstracts into an Idealist database prior to searching using keywords from clinical questions. Measurements and main results: recall and precision rates are given for each question in the ‘structured’ and the ‘unstructured’ set of records. Conclusions: Use of structured, rather than unstructured, abstracts improves precision at the ex-pense of recall and places heavier demands upon the searcher’s skill in choosing the correct fields within the abstract to search. Further investigation requires more accurate simulation of MEDLINE software that utilizes features such as MeSH terms, explode, facilities and delimiters.  相似文献

Disentangling Race: Re-Narrating Apartheid Sport?     

Douglas Booth 《国际体育史杂志》2016,33(15):1866-1883

Abstract

This paper involves a search for interracial entanglements in South African sport and considers how these experiences may be narrated. The paper comprises three sections. The first provides an overview of traditional narratives of apartheid and apartheid sport that focus on race as a perpetual marker of social division. The second section shifts attention to the gaps, blind spots, mistakes, paradoxes, ironies, anomalies, ambiguities and invisibilities in the structures of apartheid that allowed for racial encounters and entanglements. The paper concludes with a discussion about the methodological and political implications of incorporating racial entanglements into narratives of apartheid sport.  相似文献   

Comparison of individual factors in school psychology graduate students: Why do students pursue a degree in school psychology?     

Scott L. Graves JR.  Lynda Brown Wright 《Psychology in the schools》2007,44(8):865-872

The purpose of this study was to investigate what factors influenced students to enter the field of school psychology. Although numerous studies have documented the thoughts and perspectives of practitioners regarding why they have chosen to become school psychologists, attempts to recruit and retain an adequate number of school psychology practitioners and researchers have shown limited success. A national sample of 307 school psychology graduate students responded to a survey designed to measure issues related to the current state of professional practice, the influence of parental education, and professional organization recruitment. Results indicated that working with children and personal experiences within the school system were highly related to participant's decisions to become school psychologists. In addition, doctoral level and nondoctoral level students present similar reasons for entering the field. This research is discussed in terms of its implications for future research and the current shortage of school psychology practitioners and faculty. © 2007 Wiley Periodicals, Inc.

Mathematical Flexibility: Aspects of a Continuum and the Role of Prior Knowledge     

Kristie J. Newton  Karin Lange  Julie L. Booth 《Journal of Experimental Education》2020,88(4):503-515

Abstract

Psychologists and mathematics educators have long viewed flexibility as critical to students’ mathematical development. In this paper, we focused on the multidimensional nature of flexibility to better understand how preference, knowledge, and use of effective methods for solving algebra problems are related. In Study 1, we identified research-based aspects of flexibility with algebra and assessed students on them following a two-step equations unit. Results indicated that certain aspects of flexibility develop prior to others and that prior knowledge of algebra plays a significant role in that development. Study 2 confirmed and elaborated on these results using a larger sample size. Implications for theory and for supporting flexibility in classrooms are discussed.  相似文献   

Toddlers' Attachment Security to Child-Care Providers: The Safe and Secure Scale     

Cathryn L. Booth  Jean F. Kelly  Susan J. Spieker  Tracy G. Zuckerman 《Early education and development》2003,14(1):83-100

Attachment relationships of toddlers (N = 45) to their child-care providers were investigated. Children's behaviors with their mothers were observed at home at 24 months and with their child-care providers at 26 months. Attachment Q-Sort procedures were used at home (90 items) and in child care (78 items); the latter yielded a 15-item Safe and Secure Scale describing the safe haven and secure base functions of attachment relationships in child care—being able to (a) seek and receive positive attention, (b) feel safe and protected, (c) receive support for exploration, (d) receive consolation when distressed, and (e) seek and accept assistance. Independent observational measures of child-care quality also were obtained at 24 months. As hypothesized, the Safe and Secure Scale was related to proximal rather than distal indicators of child-care quality, and it was a stronger measure than the child-caregiver Q-security score that was based on all 78 items. Child-mother and child-caregiver security were significantly related.  相似文献

Teaching and nurturing: changing conceptions of self as teacher in a case study of becoming a teacher     

Robert V. Bullough JR  J. Gary Knowles 《International journal of qualitative studies in education》2013,26(2):121-140

Interest is growing in better understanding how teachers think and how they come to think like teachers. From a theoretical orientation informed by insights gained from symbolic inter‐actionism, recent research in the role metaphors play in self‐understanding, and schema theory, the authors present a case study of the first year of teaching of a divorced mother of five young children. Over the course of the year this teacher's understanding of herself as teacher changes, as indicated by changes in her personal teaching metaphor, teacher is nurturer. The reasons for these changes are explored. Of particular note is the struggle this teacher has balancing the demands of home and work. Finally, some implications for teacher education are discussed.  相似文献   

Science in the middle years     

Norman Booth 《Education 3-13》2013,41(2):37-41

This paper uses information obtained from a group of primary teachers during their first year as teachers. It uses illustrations from their experience of induction to suggest some strategies that teachers and schools might consider if they wish to make the induction period one of opportunities to learn as well as to survive.  相似文献
