Goodness-of-fit tests for a heavy tailed distribution

For testing whether a distribution function is heavy tailed, we study the Kolmogorov test, Berk-Jones test, score test and their integrated versions. A comparison is conducted via Bahadur efficiency and simulations. The score test and the integrated score test show the best performance. Although the Berk-Jones test is more powerful than the Kolmogorov-Smirnov test, this does not hold true for their integrated versions; this differs from results in \\citet{EinmahlMckeague2003}, which shows the difference of Berk-Jones test in testing distributions and tails

Constructing a Collocation Learning System from the Wikipedia Corpus

The importance of collocations for success in language learning is widely recognized. Concordancers, originally designed for linguists, are among the most popular tools for students to obtain, organize, and study collocations derived from corpora. This paper describes the design and development of a collocation learning system that is built from Wikipedia text and provides language learners with an easy-to-use interface for looking up collocations of any word that occurs in Wikipedia. The use of this corpus exposes learners to contemporary, content-related text, and enables them to search for semantically related words for a given topic. The system organizes collocations by syntactic pattern, sorts them by frequency, and links them to their original context. The paper includes a practical user guide to illustrate how to use the system as a language aid to facilitate academic writing

THE EFFECTS OF CORE STABILITY TRAINING ON THE FUNCTIONAL MOVEMENT SCREEN AND POSTURAL STABILITY IN COLLEGIATE STUDENTS

This study evaluated effects of core stability training (CST) on the functional movement screen (FMS) and postural stability (PS) in healthy young collegiate students. 28 healthy collegiate female students were assigned to an experimental (CST exercises twice a week for six weeks) or control group (equal time of warm-up and stretching exercises only). The CST combined Pilates and Swiss ball exercise for fifty minutes, twice per week, for six weeks. FMS scores were evaluated by a certified professional. The PS was evaluated by the 8-direction limits of stability (LOS) test using the Biodex Balance System. Repeated measures analyses of variance (ANOVAs) revealed the FMS and LOS performances in the experiment group were significantly improved after training. It was concluded that regular CST can improve the performance of FMS and dynamic postural stability in healthy young students

THE EFFECTS OF CORE STABILITY TRAINING ON DYNAMIC BALANCE IN HEALTHY YOUNG STUDENTS

The purpose of this study was to evaluate the effects of core stability training (CST) on dynamic balance in healthy young students. 24 healthy collegiate female students volunteered and underwent a series of CST exercise. Dynamic balance was evaluated by the 8-direction limits of stability (LOS) test. The CST combined the Pilates mat and Swiss ball exercise, ninety minutes, twice per week, for six weeks. The LOS performance in right and backward-right directions at level 3 was significant improved in post-training than pre-training. Furthermore, The LOS performance in overall, forward, right, forward,left, backward-right, and backward-left directions at level 6 were significant improved in post-training than pre-training. It is concluded that regular CST can improve the dynamic postural stability in healthy young students
