Inference Based on the Best-Fitting Model Can Contribute to the Replication Crisis: Assessing Model Selection Uncertainty Using a Bootstrap Approach     

Gitta H. Lubke  Ian Campbell 《Structural equation modeling》2016,23(4):479-490

Inferences and conclusions drawn from model fitting analyses are commonly based on a single “best fitting” model. If model selection and inference are carried out using the same data model selection, uncertainty is ignored. We illustrate the Type I error inflation that can result from using the same data for model selection and inference, and we then propose a simple bootstrap-based approach to quantify model selection uncertainty in terms of model selection rates. A selection rate can be interpreted as an estimate of the replication probability of a fitted model. The benefits of bootstrapping model selection uncertainty are demonstrated in growth mixture analyses of data from the National Longitudinal Study of Youth, and a 2-group measurement invariance analysis of the Holzinger–Swineford data.  相似文献   

Sexual reconviction rates in the United Kingdom and actuarial risk estimates     

Craig LA  Browne KD  Stringer I  Hogue TE 《Child abuse & neglect》2008,32(1):121-138

OBJECTIVE: Assessing the risk of further offending behavior by adult sexual perpetrators of children is highly relevant and important to professionals involved in child protection. Recent progress in assessing risk in sexual offenders has established the validity of actuarial measures, although there continues to be some debate about the application of these instruments. This paper summarizes the debate between clinical and actuarial approaches and reviews the "base rate" for United Kingdom sexual offense reconviction. METHOD: A review of the literature revealed 16 UK sexual reconviction studies, 8 using incarcerated samples (N=5,915) and 8 using non-incarcerated samples (N=1,274). UK estimates of sexual reconviction rates are compared with European and North American studies. RESULTS: The mean sexual reconviction rates for the incarcerated sample at 2 years (6.0%), 4 years (7.8%) and 6 years or more (19.5%) were higher than that of the comparative non-incarcerated sample at 2 years (5.7%), up to 4 years (5.9%), and 6 years or more (15.5%). The overall sexual reconviction rate for both samples combined was 5.8% at 2 years, and 17.5% at 6 years or more. CONCLUSIONS: The sexual reconviction rate for incarcerated sexual offenders is higher than that of non-incarcerated sexual offenders. The UK sexual reconviction rates were comparable with European and North American studies.  相似文献   

Jack in two boxes: A postmodern perspective on the transformation of persons into portraits   总被引：1，自引：0，他引：1  

Maggie MacLure  Ian Stronach 《Interchange》1993,24(4):353-380

The paper explores issues surrounding portrayal in educational research and interrogates the notion of a life as a textual product, via an analysis of two short biographical narratives which happen to portray the same person — a British primary school head teacher nearing the end of his career. The discrepancies between these two texts point to the problematic nature of the relationship between person and portrait, and make visible some of the textual devices that writers/researchers use in order to achieve coherence and authenticity in biographical narratives.  相似文献   

Children with epilepsy in school: Special service usage and assessment practices     

David L. Wodrich  Allen M. Kaplan  William M. Deering 《Psychology in the schools》2006,43(2):169-181

Special services usage and related assessment procedures were investigated for 50 students with epilepsy. Fifty‐six percent of students with epilepsy received special education services, with mental retardation designation and self‐contained placement common, especially among individuals with epilepsy plus a coexisting neurological diagnosis. Sixteen percent of participants had an “other health impairment” designation, and several of these were deemed eligible in at least one other special education category. The majority of students who had been evaluated were administered IQ, adaptive behavior, speech/language, and sensorimotor components, whereas few were assessed for executive or memory functions. Little information about antiepileptic drugs, their effects, or the actual manifestation of students' seizures appeared in special services school documents. Additional empirical information regarding services for children with chronic health conditions, such as epilepsy, is necessary to improve school psychologists' practice. © 2006 Wiley Periodicals, Inc.

Roots and Rhizomes—Some Reflections on Contemporary Pedagogy     

Ian Munday 《Journal of Philosophy of Education》2012,46(1):42-59

During this article, I look at three images of thought which feature in Deleuze and Guattari's A Thousand Plateaus and consider their relevance to contemporary pedagogy. Deleuze and Guattari begin by discussing tree‐like thought, which involves an insular depiction of the world. I suggest that the performative apparatus, which structures contemporary pedagogy in the comprehensive school, is also tree‐like. Deleuze and Guattari's second image of thought is the fascicular root. Here the principle root is aborted leading to a multiplicity, which flows from it. With fascicular thought, the unity, which is aborted in the object, is returned to in the subject who gains control of multiplicities. In this section I provide a reading of a Classics lesson portrayed in The Secret History by Donna Tartt and go on to focus on Ronald Barnett's contribution to a debate with Paul Standish, which features in The Blackwell Guide to the Philosophy of Education. In the third section of the article, I consider Deleuze and Guattari's third image of thought—the rhizome. Rhizomes grow by a process of cloning or lateral spreading; they do not have the central trunk of the tree, with roots and branches extending outwards from this. At the end of this section, I look at two Classics lessons that represent tree‐like and rhizomatic pedagogies in turn. I attempt to enrich this discussion by providing a reading of a scene from The History Boys.  相似文献   

Social inclusivity,cultural diversity and online film consumption     

Ian Huffer 《Cultural Trends》2017,26(2):138-154

It has been argued that the circulation of film online is a “democratising process”, evident in the breadth and depth of international film now available online, and in the greater ease of access to this content for audiences across the world. This is seen by some to present greater commercial opportunities for film-making from countries marginalised by previous distribution networks, and to foster a more globally diverse and inclusive film-viewing culture, with particular benefits for diasporic populations. Others, however, have pointed to the way in which audiences’ engagement with film online may be constrained by the economics and technology of online distribution and cultural competencies rooted in social stratification. These factors may limit how and what audiences watch, extending beyond issues of physical access to those of cultural access. As such, they raise questions regarding the demographic composition of the audience for online methods of film distribution and different types of international film. We lack sufficient understanding of these issues, however, due to the limited emphasis upon socio-demographic variables in existing academic research into online film consumption, and the limited consideration of particular film content in relevant market research. This article uses original audience research to interrogate the extent to which online distribution is able to connect audiences to a diversity of international film in comparison to other methods of distribution. It also considers some of the socio-demographic characteristics of the audiences for different methods of distribution and types of international film. In doing so, the article grants us a clearer understanding of the degree to which online film distribution fosters diversity and inclusivity through the connections it facilitates between audiences and content.  相似文献

Development and Use of a Conceptual Survey in Introductory Quantum Physics     

Sura Wuttiprom  Ian D. Johnston  Ratchapak Chitaree  Chernchok Soankwan 《International Journal of Science Education》2013,35(5):631-654

Conceptual surveys have become increasingly popular at many levels to probe various aspects of science education research such as measuring student understanding of basic concepts and assessing the effectiveness of pedagogical material. The aim of this study was to construct a valid and reliable multiple‐choice conceptual survey to investigate students’ understanding of introductory quantum physics concepts. We examined course syllabi to establish content coverage, consulted with experts to extract fundamental content areas, and trialled open‐ended questions to determine how the selected content areas align with students’ difficulties. The questions were generated and trialled with different groups of students. Each version of the survey was critiqued by a group of discipline and teaching experts to establish its validity. The survey was administered to 312 students at the University of Sydney. Using the data from this sample, we performed five statistical tests (item difficulty index, item discrimination index, item point biserial coefficient, KR‐21 reliability test, and Ferguson’s delta) to evaluate the test’s reliability and discriminatory power. The result indicates that our survey is a reliable test. This study also provided data from which preliminary findings were drawn on students’ understandings of introductory quantum physics concepts. The main point is that questions which require an understanding of the standard interpretations of quantum physics are more challenging for students than those grouped as non‐interpretative. The division of conceptual questions into interpretive and non‐interpretive needs further exploration.  相似文献
