“The Nation Stands Behind You”: Mobilizing Social Support on 38pitches.com     

Jimmy Sanderson 《Communication quarterly》2013,61(2):188-206

This research explored social support expressions to and for Boston Red Sox pitcher, Curt Schilling, in response to troubling events he disclosed on his blog, www.38pitches.com. An interpretive analysis of 514 comments posted by blog readers to Schilling's blog entries was conducted. The analysis revealed that, via their supportive postings, blog readers emerged as a mobilized support group who authenticated Schilling's identity as a sports media critic and active sports media participant while also cementing his legacy in Red Sox culture. The analysis suggests that blogs possess valuable public relations utility for professional athletes, particularly for those who have combative relationships with sports journalists, as social support is covertly obtained, enabling professional athletes to preserve “face” while simultaneously garnering support for their views.  相似文献   

Modeling actions of PubMed users with n-gram language models     

Jimmy Lin  W. John Wilbur 《Information Retrieval》2009,12(4):487-503

Transaction logs from online search engines are valuable for two reasons: First, they provide insight into human information-seeking behavior. Second, log data can be used to train user models, which can then be applied to improve retrieval systems. This article presents a study of logs from PubMed^®, the public gateway to the MEDLINE^® database of bibliographic records from the medical and biomedical primary literature. Unlike most previous studies on general Web search, our work examines user activities with a highly-specialized search engine. We encode user actions as string sequences and model these sequences using n-gram language models. The models are evaluated in terms of perplexity and in a sequence prediction task. They help us better understand how PubMed users search for information and provide an enabler for improving users’ search experience.  相似文献

Aminotransferase assay is often used as a screening test as well as an endpoint for resolution of disease in nonalcoholic fatty liver disease (NAFLD). Aim of the study was to evaluate the relationship of transaminase level with metabolic variables and histology in NAFLD. Single center observational study was conducted in a gastroenterology clinic at Cuttack in coastal Odisha. Subjects were consecutive patients presenting with functional bowel disease and undergoing abdominal sonography. All participants were evaluated for the presence of metabolic syndrome (MS), insulin resistance, liver function test and lipid profile. Various parameters were compared between NAFLD subjects and controls. 53.5 % of NAFLD had normal serum transaminases, whereas 20.8 % of healthy controls had transaminitis. NAFLD patients had significantly higher BMI, fasting plasma glucose, serum transaminases, serum triglycerides, serum insulin and homeostatic model assessment (HOMA) IR than controls. NAFLD patients who had transaminitis had significantly higher incidence of MS and higher mean HOMA IR than those without. There was no significant difference in histopathological features between NAFLD with and without transaminitis. To conclude, over half of NAFLD subjects do not have transaminitis while transaminitis is present in a fifth of healthy people without fatty liver. Hence serum transaminase should not be used as screening test for NAFLD. NAFLD patients with transaminitis had a higher incidence of MS and insulin resistance than those without. However, there was no significant difference in histopathological features between these two groups.  相似文献   

A comparison between the WISC and WISC-R among educable mentally retarded students     

Harry Hamm  Jimmy Wheeler  Steve McCallum  Maurice Herrin  Dorothy Hunter  Carol Catoe 《Psychology in the schools》1976,13(1):4-8

The study compared differences and similarities between WISC and WISC-R scores for 48 ten- and thirteen-year-old EMR students, who were matched according to sex and race. The WISC-R yielded significantly lower VS, PS, and FS IQ scores than the WISC for this predominantly rural Georgia population. The FS IQ scores from the WISC-R averaged 7.5 points lower than the WISC FS IQs, with similar differences noted for VS and PS scores. There was no significant difference in FS IQs between the two age groups. Results suggest that many children classified as “Borderline” or slightly above by the WISC will be classified as “Mentally Deficient” by the WISC-R.  相似文献

An Empirically Based Method of Q‐Matrix Validation for the DINA Model: Development and Applications     

Jimmy De La Torre 《Journal of Educational Measurement》2008,45(4):343-362

Most model fit analyses in cognitive diagnosis assume that a Q matrix is correct after it has been constructed, without verifying its appropriateness. Consequently, any model misfit attributable to the Q matrix cannot be addressed and remedied. To address this concern, this paper proposes an empirically based method of validating a Q matrix used in conjunction with the DINA model. The proposed method can be implemented with other considerations such as substantive information about the items, or expert knowledge about the domain, to produce a more integrative framework of Q‐matrix validation. The paper presents the theoretical foundation for the proposed method, develops an algorithm for its practical implementation, and provides real and simulated data applications to examine its viability. Relevant issues regarding the implementation of the method are discussed.  相似文献   

Lehrerbildung fur den Unterricht Behinderter Kinder in der UdSSR     

Gerda Freiburg  Leonid Novikov 《欧洲师范教育杂志》1984,7(3):315-328

This article is presented as an interim report on an inquiry which is being conducted at the German Institute for International Educational Research at Frankfurt/Main. The authors being by outlining the organisational structure of special school teacher training at the Faculties of Defectology which have been established at a good number of Colleges of Education. However, the emphasis is laid on identifying current curricular innovations with special regard to the experiments at the Lenin College of Education in Moscow. In the following section specific attention is paid to the function of correspondence studies in the initial and in‐service training of special school teachers. The article is concluded by some remarks about the social status that teachers enjoy in the Soviet Union and by some basic comparison with trends in special teacher education in both Germanies.  相似文献   

‘A process where we’re all at the table’: community archives challenging dominant modes of archival practice     

Jimmy Zavala  Alda Allina Migoni  Michelle Caswell  Noah Geraci  Marika Cifor 《档案与原稿》2017,45(3):202-215

Community archives have compelled shifts in dominant archival management practices to reflect community agency and values. To analyse these shifts, we ask: In what ways do community archives and their staff challenge traditional archival modes of practice? Do community archives work within or against dominant frameworks for institutional sustainability? Do community archives challenge or replicate dominant custody practices? Based on semi-structured interviews with 17 founders, staff and volunteers at 12 Southern California community archives, this research examines the diverse models of practice utilised by community archives practitioners that diverge from and challenge standard practices in the field. By addressing these questions, our research uncovers a variety of models of practice employed by communities in Southern California to autonomously create and sustain their archives.  相似文献   

Effects of gluteal kinesio-taping on performance with respect to fatigue in rugby players     

Gerda Strutzenberger  Joseph Moore  Hywel Griffiths  Hermann Schwameder  Gareth Irwin 《European Journal of Sport Science》2016,16(2):165-171

Kinesio-tape^® has been suggested to increase blood circulation and lymph flow and might influence the muscle's ability to maintain strength during fatigue. Therefore, the aim of this study was to investigate the influence of gluteal Kinesio-tape^® on lower limb muscle strength in non-fatigued and fatigued conditions. A total of 10 male rugby union players performed 20-m sprint and vertical jump tests before and after a rugby-specific fatigue protocol. The 20-m sprint time was collected using light gates (SMARTSPEED). A 9-camera motion analysis system (VICON, 100 Hz) and a force plate (Kistler, 1000 Hz) measured the kinematics and kinetics during a counter movement jump and drop-jump. The effect of tape and fatigue on jump height, maximal vertical ground reaction force, reactivity strength index as well as lower limb joint work were analysed via a two-way analysis of variance. The fatigue protocol resulted in significantly decreased performance of sprint time, jump heights and alterations in joint work. No statistical differences were found between the taped and un-taped conditions in non-fatigued and fatigued situation as well as in the interaction with fatigue. Therefore, taping the gluteal muscle does not influence the leg explosive strength after fatiguing in healthy rugby players.  相似文献
