Using Testlet Response Theory to Examine Local Dependence in C-Tests     

Thomas Eckes 《教育实用测度》2015,28(2):85-98

C-tests are gap-filling tests widely used to assess general language proficiency for purposes of placement, screening, or provision of feedback to language learners. C-tests consist of several short texts in which parts of words are missing. We addressed the issue of local dependence in C-tests using an explicit modeling approach based on testlet response theory. Data were provided by a total sample of 4,708 participants working on eight C-test texts with 20 gaps each. The resulting parameter estimates were compared to those obtained from (a) a polytomous item response theory (IRT) model and (b) a standard IRT model that ignored the dependence structure. Testlet effects proved to be very small and correspondence between parameters obtained from the different modeling approaches was high. When local dependence was ignored reliability of the C-test was slightly overestimated. Implications for the analysis of testlets in general, and C-tests in particular are discussed.  相似文献   

Factors affecting successful reintegration     

David Vittle Thomas 《Educational studies》2015,41(1-2):188-208

This study explores the perspectives of education practitioners towards the process of reintegrating pupils (many of whom display social, emotional and behavioural difficulties), from a pupil referral unit (PRU) to mainstream educational provision in a rural bilingual Welsh authority, and examines the barriers and facilitators they identified as evident within their individual schools and catchment area served with regards to reintegrating and including pupils. The study locates the process within a specific geographical context and discusses whether there are specific reintegration barriers and facilitators inherent within the setting. Patterns of pupil referral and reintegration between the PRU and mainstream schools were examined and analysed from “pupil tracking data” which tracked pupils throughout an academic year from their arrival at the PRU before the perspectives of education practitioners towards potential reintegration barriers and facilitators were gathered through an initial expert sample and a second landscape sample postal questionnaire. Interviews were subsequently conducted with respondents from Primary, Secondary and PRU settings to drill down into the influence of specific barriers and facilitators identified earlier. This study suggests that although generic reintegration barriers and facilitators may be evident within all settings, there were specific factors inherent within this geographical context identified by education practitioners, which acted in the most part as barriers to successful reintegration and inclusion.  相似文献   

Simulation and experimental determination of the online separation of blood components with the help of microfluidic cascading spirals     

Lisa Sprenger  Silvio Dutz  Thomas Schneider  Stefan Odenbach  Urs O. H?feli 《Biomicrofluidics》2015,9(4)

Microfluidic spirals were used to successfully separate rare solid components from unpretreated human whole blood samples. The measured separation ratio of the spirals is the factor by which the concentration of the rare component is increased due to the Dean effect present in a flow profile in a curved duct. Different rates of dilution of the blood samples with a phosphate-buffered solution were investigated. The diameters of the spherical particles to separate ranged from 2 μm to 18 μm. It was found that diluting the blood to 20% is optimal leading to a separation ratio up to 1.97. Using two spirals continuously placed in a row led to an increase in separation efficacy in samples consisting of phosphate-buffered solution only from 1.86 to 3.79. Numerical investigations were carried out to display the flow profiles of Newtonian water samples and the shear-thinning blood samples in the cross-section of the experimentally handled channels. A macroscopic difference in velocity between the two rheologically different fluids could not be found. The macroscopic Dean flow is equally present and useful to help particles migrate to certain equilibrium positions in blood as well as lower viscous Newtonian fluids. The investigations highlight the potential for using highly concentrated, very heterogeneous, and non-Newtonian fluidic systems in known microsystems for screening applications.  相似文献   

Standing Out from the Crowd: Imaging Baseball Fans through Sculpture     

Christopher Stride  Ffion Thomas  Gregory Ramshaw 《国际体育史杂志》2015,32(14):1611-1638

Sculptures of athletes that immortalize heroic feats have long been part of the sporting world. More recently, statues of sports fans have appeared, particularly at baseball stadiums across North America. Whilst athlete statues usually represent specific subjects, fan statues typically depict anonymous figures, giving commissioners and sculptors broader license to incorporate particular ideals. This paper investigates how the fan statuary's form reflects commissioners' motivations, values, and views of fandom, and whether fan statues promote a preferred (but often imaginary) narrative regarding the fan experience. A tripartite fan statue design typology is proposed: hero worship, family experiences, and the crowd. By examining an example of each type, with context provided by a unique database of baseball statuary, the fan statuary's predominant themes and tensions are illustrated. Fan statues are concentrated at Minor League ballparks, and all feature children. The majority are alloys of both real and imagined components of the idealized fan experience of the baseball organization's ‘ideal fan’, projecting inclusive, family-friendly, and timeless game day experiences, and evoking nostalgia for childhood. Crowd-type statues offer a more free-spirited and spontaneous aesthetic, with the crowd creating and becoming part of the spectacle – a reality that sports organizations may be less comfortable with.  相似文献   

A Roundabout Revolution: Rethinking the Decolonization of Rwanda by the Practices of the Catholic Scouting Movement, 1954–1964     

Thomas Riot 《国际体育史杂志》2015,32(7):939-951

Modelling itself on the organizational structure and the physical fitness culture of Catholic scouting, the xaveri movement in Rwanda developed within a climate which was highly susceptible to the development of deep racial and political divisions. Between 1954 and 1964, this Catholic youth organization was influential in the gestation of a Christian democratic culture which was one of the essential elements of the ideology behind the ‘Hutu revolution’. Covering the colonial to the postcolonial period and from the angle of the rise of the xaveri movement, this paper shows how the ‘Hutu revolution’ was a consequence of a liberation struggle from an imagined oppressor. This is in reference to colonial privileges attributed (until the end of the 1940s) to the Tutsi minority. However, and still from the perspective of the organization explored here, it seems that the model of the ‘civilised Tutsi’ targeted by the revolutionary Hutu movement was the essential referent of the more subconscious invention by republican leaders.  相似文献   

The NICE OECD countries’ geographic search filters: Part 1—methodology for developing the draft MEDLINE and Embase (Ovid) filters     

Lynda Ayiku  Paul Levay  Thomas Hudson 《Journal of the Medical Library Association》2021,109(2):258

Objective:There are no existing validated search filters for the group of 37 Organisation for Economic Co-operation and Development (OECD) countries. This study describes how information specialists from the United Kingdom''s National Institute for Health and Care Excellence (NICE) developed and evaluated novel OECD countries’ geographic search filters for MEDLINE and Embase (Ovid) to improve literature search effectiveness for evidence about OECD countries.Methods:We created the draft filters using an alternative approach to standard filter construction. They are composed entirely of geographic subject headings and are designed to retain OECD country evidence by excluding non-OECD country evidence using the NOT Boolean operator. To evaluate the draft filters’ effectiveness, we used MEDLINE and Embase literature searches for three NICE guidelines that retrieved >5,000 search results. A 10% sample of the excluded references was screened to check that OECD country evidence was not inadvertently excluded.Results:The draft MEDLINE filter reduced results for each NICE guideline by 9.5% to 12.9%. In Embase, search results were reduced by 10.7% to 14%. Of the sample references, 7 of 910 (0.8%) were excluded inadvertently. These references were from a guideline about looked-after minors that concerns both OECD and non-OECD countries.Conclusion:The draft filters look promising—they reduced search result volumes while retaining most OECD country evidence from MEDLINE and Embase. However, we advise caution when using them in topics about both non-OECD and OECD countries. We have created final versions of the search filters and will validate them in a future study.  相似文献   

Quality assessment of service bundles for governmental one-stop portals: A literature review     

Thomas Kohlborn 《Government Information Quarterly》2014

Service bundles, in the context of e-government, are used to group services together that relate to a certain citizen need. These bundles can then be presented on a governmental one-stop portal to structure the available service offerings according to citizen expectations. In order to ensure that citizens utilise the one-stop portal and comprised service bundles for future transactions, the quality of these service bundles needs to be managed and maximised accordingly. Consequently, models and tools that focus on assessing service bundle quality play an important role, when it comes to increasing or retaining usage behaviour of citizens. This study focuses on providing a rigorous and structured literature review of e-government outlets with regard to their coverage of service bundle quality and e-service quality themes. The study contributes to academia and practice by providing a framework that allows structuring and classifying existing studies relevant for the assessment of quality for government portals. Furthermore, this study provides insights into the status quo of quality models that can be used by governments to assess the quality of their service bundles. Directions for future research and limitations of the present study are provided as well.  相似文献
