The publishing imperative: the pervasive influence of publication metrics     

Colin Steele  Linda Butler  Danny Kingsley 《Learned Publishing》2006,19(4):277-290

This article summarizes the effects of the increasing global trend towards measuring research quality and effectiveness through, in particular, publication‐based metrics, and its effects on scholarly communication. Such metrics are increasingly influencing the behaviour patterns of administrators, publishers, librarians, and researchers. Impact and citation measures, which often rely solely on Thomson Scientific data, are examined in the context of university league tables and research assessment exercises. The need to establish alternate metrics, particularly for the social sciences and humanities, is emphasized, as is an holistic approach to scholarly communication agenda.  相似文献   

The case for acquisitions standards in the integrated library system     

Katharine Treptow Farrell  Marc Truitt   《Library Collections, Acquisitions, and Technical Services》2004,27(4):42-492

Acquisitions metadata within current library integrated systems is not based on any standard; rather, systems vendors generally define structure and content according to proprietary approaches. The authors argue that this cripples library acquisitions practitioners and managers in numerous ways. It renders routine tasks more difficult, jeopardizes the integrity of data during system migration, forces adoption of costly external tracking solutions, and hinders efforts to manage collections and budgets. The authors define acquisitions standards and relate them to existing bibliographic and e-commerce protocols. They discuss reasons for the lack of acquisitions standards and outline first steps in a project to develop them. This paper is based on a presentation given at the Acquisitions Institute at Timberline Lodge, Fourth Annual Conference, held 17-20 May 2003.  相似文献

Validity of Self-Reported Pedometer Steps per Day in College Students     

Brittany Star Overstreet  Scott E. Crouter  George A. Butler  Cary M. Springer  David R. Bassett 《Measurement in physical education and exercise science》2016,20(3):140-145

The purpose of this article was to examine the validity of self-reported pedometer steps/day. Forty-seven participants were provided a New Lifestyles NL-2000 (NL-2000; Lees Summit, MO, USA) pedometer and a physical activity (PA) diary for 3 weeks, but not informed of the data-storing capabilities. For weeks 2 and 3, each participant was given a step goal of 3,000 steps/day above week 1 average. A 2 × 3 repeated measures analysis of variance (ANOVA) was used to examine differences between reported steps/day. Bland–Altman plots assessed the mean bias and limits of agreement between reporting methods. Mean self-reported and NL-2000 steps/day were 9,264 ± 3,555 and 8,971 ± 3,590 steps/day (n = 26, p > .05). Mean biases were 216 ± 1,753 (week 1), –506 ± 1,355 (week 2), and –590 ± 1,360 (week 3) steps/day. Negative mean bias values indicate higher self-reported steps/day. Mean steps/day were similar between recording methods, but large differences were observed among individuals, suggesting self-reported steps/day may be valid for PA research at the population level, but not the individual level.  相似文献   

Games and simulations: Creative educational alternatives     

J. Thomas Butler 《TechTrends》1988,33(4):20-23

Summary Active participation is the foundation of learning through the media of games and simulations. The actual doing by the students is the important element. Games and simulations, if properly designed and applied, can meet a variety of classroom objectives. A vast array of educational games and simulations has been designed and many are available commercially. However, a skilled and innovative instructor can apply certain guidelines to custom design activities for the individual classroom. Involving students in the design and modification of games and simulations is recommended.  相似文献   

Reading Rescue: A follow-up on effectiveness of an intervention for struggling readers     

Katharine Pace Miles  Mark D. Lauterbach  Dana M. Murano  Ginny A. Dembek 《The Journal of educational research》2019,112(2):255-269

The authors examined whether Reading Rescue continues to be an effective literacy intervention and factors that impact its effectiveness. Data were collected on 143 first-grade students, tutored by 104 tutors at 38 schools. There was significant growth on all foundational skills (ps?ps?d?=?1.62 sight words, d?=?1.68 oral reading/comprehension). Student-level factors of Individualized Education Program status, program completion, number of session, and invented spelling; tutor-level factors of sessions delivered and years of experience; school level factors of school size and percentage of language minority students all predicted grade-level passage or word reading (all ps?2007 Ehri, L.

Efforts should focus on ensuring program completion and increasing program exposure in neediest schools.  相似文献

An Expanded View of Joint Attention: Skill,Engagement, and Language in Typical Development and Autism     

Lauren B. Adamson  Roger Bakeman  Katharine Suma  Diana L. Robins 《Child development》2019,90(1):e1-e18

This study provides an expanded view of joint attention and its relation to expressive language development. A total of 144 toddlers (40 typically developing, 58 with autism spectrum disorder [ASD], 46 with developmental delay [DD]) participated at 24 and 31 months. Toddlers who screened positive for ASD risk, especially those subsequently diagnosed with ASD, had poorer joint attention skills, joint engagement during parent–toddler interaction, and expressive language. Findings highlight the dynamic relation between joint attention and language development. In the ASD and DD groups, joint engagement predicted later expressive vocabulary, significantly more than predictions based on joint attention skills. Joint engagement was most severely impacted when toddlers did not talk initially and improved markedly if they subsequently began to speak.  相似文献   

Discrimination and Ethnic–Racial Identity: Understanding Direction of Effects Using Within- and Between-Person Analyses     

Katharine H. Zeiders  Sara D. Bayless  Chelsea L. Derlan  Adriana J. Umaña-Taylor  Kimberly A. Updegraff  Laudan B. Jahromi 《Child development》2019,90(3):e373-e385

Ethnic–racial identity (ERI) development and ethnic–racial discrimination are two salient experiences among adolescents in the United States. Despite growing awareness of the costs and benefits of these experiences individually, we know little about how they may influence one another. The current study examined competing hypotheses relating discrimination and components of ERI (i.e., exploration, resolution, affirmation) among a sample of Mexican-origin adolescent mothers (N = 181; M_age at Wave 1 = 16.83, SD = 1.01) across six waves of data. Findings revealed that within-person changes in discrimination predicted subsequent ERI resolution and affirmation; however, ERI did not predict subsequent discrimination. Between-person effects of discrimination on affirmation were significant. Our findings underscore the importance of discrimination experiences in shaping Mexican-origin adolescent mothers’ normative developmental competencies.  相似文献   

Standards-to-Standards Linkage Under Title III: Exploring Common Language Demands in ELD and Science Standards     

Alison L. Bailey  Frances A. Butler  Edynn Sato 《教育实用测度》2013,26(1):53-78

A great deal of measurement research is currently being utilized to improve instruction at the elementary and secondary levels, but many opportunities for improving utilization are still untapped. The author proposes specific approaches to increased collaboration between researchers and practitioners to meet the burgeoning research needs of the nations' schools and to assist in data-based decision-making efforts. Society's increasing demands for accurate, usable data have contributed to the urgent current need for viable, appropriate research. This need can be met only by reseachers and practitioners working together to provide answers to critical educational questions.  相似文献
