High bar swing performance in novice adults: effects of practice and talent     

Busquets A  Marina M  Irurtia A  Ranz D  Angulo-Barroso RM 《Research quarterly for exercise and sport》2011,82(1):9-20

An individual's a priori talent can affect movement performance during learning. Also, task requirements and motor-perceptual factors are critical to the learning process. This study describes changes in high bar swing performance after a 2-month practice period. Twenty-five novice participants were divided by a priori talent level (spontaneous-talented [ST] and nonspontaneous-talented [NST]) and compared to experienced gymnasts. Additionally, we assessed their perception of their performance level before and after practice. We defined three events independently for hip (H) and shoulder (S) angle joints and for the lag between consecutive events (phases [P]): the smallest angle during downswing (P1H, P1S), the largest angle after P1 (P2H, P2S), and the smaller angle during upswing (P3H, P3S). Movement performance variables were the maximum elevation on the downswing (Pi) and the upswing (Pf), and the total path between both (swing amplitude). Data were collected during pre- and postpractice sessions by two video cameras. At the end of both sessions, participants drew a sketch to represent their perception of their performance level relative to the Pi, Pf and the hip events. Results showed a similar practice effect in the swing amplitude in both novice groups. However the ST group 's performance and perception variables on the downswing improved more than the NST group due to practice. This study suggests that (a) downswing improvements were easier than in the upswing, possibly due to familiarity of the visual reference in combination with proprioceptive feedback; and (b) being ST may involve a better orfaster gain in perception of self-action compared to NST.  相似文献   

Can learning of basketball be enhanced through a web-based multimedia course? An experimental study     

Marina Papastergiou  Vassilis Gerodimos 《Education and Information Technologies》2013,18(3):459-478

This study’s aim is the creation of a web-based multimedia course for Physical Education (PE) students’ familiarization with the teaching of basketball, and the evaluation of its use as a complementary tool to conventional instruction, in terms of learning effectiveness and student acceptance. The course includes multimedia learning material as well as interactive learning activities and quizzes on the cognitive components of basic basketball skills and on other basketball-related topics (history of the sport, referee’s signals, training aids, basketball court). The study involved 88 undergraduate students during one semester. They were randomly assigned to two groups: a group that used the web-based multimedia course and also attended a conventional face-to-face course on the teaching of basketball (N?=?45), and another group that only attended the conventional face-to-face course (N?=?43). A pretest/posttest research design was followed. For both groups basketball knowledge was measured at the beginning and at the end of the semester through written questionnaires. The responses of the students of the first group towards the web-based course were also assessed, at the end of the semester, through a written feedback questionnaire. Within both groups, significant increases in students’ basketball knowledge were found. However, the web-based multimedia course in combination with conventional face-to-face instruction was significantly more effective than conventional face-to-face instruction alone in increasing students’ cognitive learning regarding the sport of basketball, at the same time being well-accepted by the students. These findings support the effectiveness of blended learning for PE at higher education level as well as the acceptance of this mode of learning by PE students.  相似文献   

Cross-lingual training of summarization systems using annotated corpora in a foreign language     

Marina Litvak  Mark Last 《Information Retrieval》2013,16(5):629-656

The increasing trend of cross-border globalization and acculturation requires text summarization techniques to work equally well for multiple languages. However, only some of the automated summarization methods can be defined as “language-independent,” i.e., not based on any language-specific knowledge. Such methods can be used for multilingual summarization, defined in Mani (Automatic summarization. Natural language processing. John Benjamins Publishing Company, Amsterdam, 2001) as “processing several languages, with a summary in the same language as input”, but, their performance is usually unsatisfactory due to the exclusion of language-specific knowledge. Moreover, supervised machine learning approaches need training corpora in multiple languages that are usually unavailable for rare languages, and their creation is a very expensive and labor-intensive process. In this article, we describe cross-lingual methods for training an extractive single-document text summarizer called MUSE (MUltilingual Sentence Extractor)—a supervised approach, based on the linear optimization of a rich set of sentence ranking measures using a Genetic Algorithm. We evaluated MUSE’s performance on documents in three different languages: English, Hebrew, and Arabic using several training scenarios. The summarization quality was measured using ROUGE-1 and ROUGE-2 Recall metrics. The results of the extensive comparative analysis showed that the performance of MUSE was better than that of the best known multilingual approach (TextRank) in all three languages. Moreover, our experimental results suggest that using the same sentence ranking model across languages results in a reasonable summarization quality, while saving considerable annotation efforts for the end-user. On the other hand, using parallel corpora generated by machine translation tools may improve the performance of a MUSE model trained on a foreign language. Comparative evaluation of an alternative optimization technique—Multiple Linear Regression—justifies the use of a Genetic Algorithm.  相似文献   

Retaliatory Aggression and the Effects of Point of View and Blood in Violent Video Games     

Marina Krcmar  Kirstie Farrar 《Mass Communication and Society》2013,16(1):115-138

In this study, an experimental design was utilized to test, first, the effect of a violent game versus a no game control on physical and verbal aggression and retaliatory aggression against a confederate. In addition, the effects of two internal video game manipulations were explored. Overall, those in the violent game condition were more verbally and physically aggressive than those in the no game condition. In terms of internal game features, third-person play with the blood on, especially when combined with aggressive cognitions and to some extent, hostile affect, encouraged more aggressive outcomes.  相似文献

INTERCULTURALISM,MULTICULTURALISM, AND THE STATE FUNDING AND REGULATION OF CONSERVATIVE RELIGIOUS SCHOOLS     

Bruce Maxwell  David I. Waddington  Kevin McDonough  Andrée‐Anne Cormier  Marina Schwimmer 《Educational theory》2012,62(4):427-447

In this essay, Bruce Maxwell, David Waddington, Kevin McDonough, Andrée‐Anne Cormier, and Marina Schwimmer compare two competing approaches to social integration policy, Multiculturalism and Interculturalism, from the perspective of the issue of the state funding and regulation of conservative religious schools. After identifying the key differences between Interculturalism and Multiculturalism, as well as their many similarities, the authors present an explanatory analysis of this intractable policy challenge. Conservative religious schooling, they argue, tests a conceptual tension inherent in Multiculturalism between respect for group diversity and autonomy, on the one hand, and the ideal of intercultural citizenship, on the other. Taking as a case study Québec's education system and, in particular, recent curricular innovations aimed at helping young people acquire the capabilities of intercultural citizenship, the authors illustrate how Interculturalism signals a compelling way forward in the effort to overcome the political dilemma of conservative religious schooling.  相似文献   

Pharmacogenetics and personalized treatment of type 2 diabetes     

Sabina Semiz  Tanja Dujic  Adlija Causevic 《Biochemia medica : ?asopis Hrvatskoga dru?tva medicinskih biokemi?ara / HDMB》2013,23(2):154-171

Type 2 diabetes mellitus (T2DM) is a worldwide epidemic with considerable health and economic consequences. T2DM patients are often treated with more than one drug, including oral antidiabetic drugs (OAD) and drugs used to treat diabetic complications, such as dyslipidemia and hypertension. If genetic testing could be employed to predict treatment outcome, appropriate measures could be taken to treat T2DM more efficiently. Here we provide a review of pharmacogenetic studies focused on OAD and a role of common drug-metabolizing enzymes (DME) and drug-transporters (DT) variants in therapy outcomes. For example, genetic variations of several membrane transporters, including SLC22A1/2 and SLC47A1/2 genes, are implicated in the highly variable glycemic response to metformin, a first-line drug used to treat newly diagnosed T2DM. Furthermore, cytochrome P450 (CYP) enzymes are implicated in variation of sulphonylurea and meglitinide metabolism. Additional variants related to drug target and diabetes risk genes have been also linked to interindividual differences in the efficacy and toxicity of OAD. Thus, in addition to promoting safe and cost-effective individualized diabetes treatment, pharmacogenomics has a great potential to complement current efforts to optimize treatment of diabetes and lead towards its effective and personalized care.  相似文献
