Explaining Method Effects Associated With Negatively Worded Items in Trait and State Global and Domain-Specific Self-Esteem Scales     

José M. Tomás  Amparo Oliver  Laura Galiana  Patricia Sancho  Marisol Lila 《Structural equation modeling》2013,20(2):299-313

Several investigators have interpreted method effects associated with negatively worded items in a substantive way. This research extends those studies in different ways: (a) it establishes the presence of methods effects in further populations and particular scales, and (b) it examines the possible relations between a method factor associated with negatively worded items and several covariates. Two samples were assessed: 592 high school students from Valencia (Spain), and 285 batterers from the same city. The self-esteem scales used were Rosenberg's Self-Esteem Scale, the State Self-Esteem Scale, and Self-Esteem 17. Anxiety was also assessed with the State-Trait Anxiety Inventory, and gender and educational level were taken into account. The models were conducted using a multiple indicators and multiple causes (MIMIC) model framework. The evidence in this research pointed out that method effects were present across the different measures of self-esteem. Moreover, a significant and negative effect of anxiety on method effects was present across scales and samples, whereas no effects of age or educational level where found.  相似文献   

The Efficacy of Inquiry-Based Instruction in Science: a Comparative Analysis of Six Countries Using PISA 2015     

Oliver  Mary  McConney  Andrew  Woods-McConney  Amanda 《Research in Science Education》2019,51(2):595-616

This study is a comparative analysis of 15-year-old students’ scientific literacy, and its association with the instructional strategies that students experience, across six OECD countries that participated in PISA 2015. Across the six countries, the study investigates the efficacy of inquiry-based instruction in science in contrast with two other instructional approaches to teaching secondary science: adaptive and teacher-directed teaching. The analysis shows that students who reported experiencing high frequencies of inquiry strategies in their classrooms consistently evidenced lower levels of scientific literacy across the six countries. Benchmark analysis also showed, common to all six countries, a strongly positive association between the frequency of teacher-directed and adaptive teaching strategies and students’ scientific literacy. Additionally, the study disaggregates PISA’s composite variable representing inquiry-based instruction and shows that different components of inquiry are differentially associated with students’ scientific literacy. We discuss the implications of these analyses for science teacher educators, science teachers, and educational policy makers. In doing so, we add nuance to our understanding of the efficacy of inquiry-based instruction in science, suggesting that some components, as conceptualised and assessed in PISA, seem to suggest greater attention and use, and others more moderated use.

Sprint running kinematics and kinetics in pre-peak-height-velocity male children on a non-motorised treadmill: reliability and normative data     

Michael Clemens Rumpf  John Cronin  Jonathan Oliver  Michael Hughes 《Sports biomechanics / International Society of Biomechanics in Sports》2019,18(3):256-263

The purpose of this study was to quantify the reliability of kinematic and kinetic variables using a sample of pre-peak-height-velocity (PHV) male athletes sprinting on a non-motorised treadmill. Following variables were measured and their normative data presented, average and peak velocity, average and peak power, average and peak horizontal force, average and peak vertical force, average step frequency, average step length, average work. Twenty-five participants performed three 5-s all-out sprints from a standing split start on a non-motorised treadmill on three separate occasions. Per cent change in the means (-3.66 to 3.35%) and coefficients of variation (0.56–7.81%) were thought reliable for all variables. However, average step rate, average horizontal force and average vertical force did not meet the standards (≥0.70) set for acceptable intraclass correlation coefficients (ICC). Due to the homogeneous group, it was expected to receive low ICC values. Therefore, youth sprinting performance can be tested reliably on a non-motorised treadmill, especially if the per cent change in the mean and CV are deemed the important reliability measures. Normative data are given for the participant’s age as well as their maturity level for kinematic and kinetic variables.  相似文献   

Public health practitioners' information access and use patterns in the Maryland (USA) public health departments of Anne Arundel and Wicomico Counties     

Twose C  Swartz P  Bunker E  Roderer NK  Oliver KB 《Health information and libraries journal》2008,25(1):13-22

PURPOSE: To increase understanding of the information needs and use of public health practitioners. SETTING: From June 2005 to May 2006, the library offered a course in public health information resources to eighteen practitioners in two counties, access to the library's licensed electronic resources through a tailored web portal, and consulting services. EVALUATION METHOD: We combined usage statistics from the web portal, self-report and observational data collected during training and shadowing of participants. CONCLUSIONS: The data from this project indicate that usage of licensed information resources and services is infrequent but broad ranging. A few users register at the high end of the usage range, but one use of one high quality article can have a significant impact on policy decisions. Time and competing responsibilities often constrain the retrieval and use of resources for evidence-based decision making and an informationist or power-user model may be more appropriate than training all practitioners to integrate searching into their workflow. This study indicates (i) that evidence-based public health practice requires seamless and broadly based information access; and (ii) that the currently existing patchwork does not support the level of use or take into account the time constraints of information needs for public health practice.  相似文献   

Standardization of search methods for guideline development: an international survey of evidence-based guideline development groups     

Deurenberg R  Vlayen J  Guillo S  Oliver TK  Fervers B  Burgers J;SEARCH Group 《Health information and libraries journal》2008,25(1):23-30

BACKGROUND: Effective literature searching is particularly important for clinical practice guideline development. Sophisticated searching and filtering mechanisms are needed to help ensure that all relevant research is reviewed. PURPOSE: To assess the methods used for the selection of evidence for guideline development by evidence-based guideline development organizations. METHODS: A semistructured questionnaire assessing the databases, search filters and evaluation methods used for literature retrieval was distributed to eight major organizations involved in evidence-based guideline development. RESULTS: All of the organizations used search filters as part of guideline development. The medline database was the primary source accessed for literature retrieval. The OVID or SilverPlatter interfaces were used in preference to the freely accessed PubMed interface. The Cochrane Library, embase, cinahl and psycinfo databases were also frequently used by the organizations. All organizations reported the intention to improve and validate their filters for finding literature specifically relevant for guidelines. DISCUSSION: In the first international survey of its kind, eight major guideline development organizations indicated a strong interest in identifying, improving and standardizing search filters to improve guideline development. It is to be hoped that this will result in the standardization of, and open access to, search filters, an improvement in literature searching outcomes and greater collaboration among guideline development organizations.  相似文献

Framework for Sustaining Innovation at Baker Library,Harvard Business School     

Meghan Dolan  Stephanie Oliver 《New Review of Academic Librarianship》2017,23(2-3):275-292

ABSTRACT

Baker Library at Harvard Business School is increasingly asked by the school's faculty to create custom digital information products to enhance course assignments and to find novel ways of electronically disseminating faculty research. In order to prioritize these requests, as well as facilitate, manage, and track the resulting projects, the library staff developed the Research Innovation Framework. Informed by design thinking techniques and recent research on building innovation strategies and innovative cultures, the Research Innovation Framework has been particularly impactful to Baker's intra-organizational communication, allowing for more robust collaboration across the entire library. Tools and resources contained within the Framework have allowed Baker to adapt to the diverse and evolving needs of its customers.  相似文献

The Big-fish–little-pond-effect Stands Up to Critical Scrutiny: Implications for Theory, Methodology, and Future Research     

Herbert W. Marsh  Marjorie Seaton  Ulrich Trautwein  Oliver Lüdtke  K. T. Hau  Alison J. O’Mara  Rhonda G. Craven 《Educational Psychology Review》2008,20(3):319-350

The big-fish–little-pond effect (BFLPE) predicts that equally able students have lower academic self-concepts (ASCs) when attending schools where the average ability levels of classmates is high, and higher ASCs when attending schools where the school-average ability is low. BFLPE findings are remarkably robust, generalizing over a wide variety of different individual student and contextual level characteristics, settings, countries, long-term follow-ups, and research designs. Because of the importance of ASC in predicting future achievement, coursework selection, and educational attainment, the results have important implications for the way in which schools are organized (e.g., tracking, ability grouping, academically selective schools, and gifted education programs). In response to Dai and Rinn (Educ. Psychol. Rev., 2008), we summarize the theoretical model underlying the BFLPE, minimal conditions for testing the BFLPE, support for its robust generalizability, its relation to social comparison theory, and recent research extending previous implications, demonstrating that the BFLPE stands up to scrutiny. Quotations (associated page numbers) to the Dai and Rinn (2008) article are based on a prepublication version of the article available to the authors of this article that may have changed during the final preparation for publication. The authors would also like to express thanks to David Dai and Anne Rinn for their encouragement and assistance to us in preparation of our article, whilst still acknowledging that they might not agree will all the views expressed here.  相似文献
