The Summated-Heart-Rate-Zones training load (SHRZ TL) model is used to measure internal loading; however, a major limitation of this approach is the use of broad heart rate (HR) zones to quantify exercise intensity. Therefore, this study aimed to compare SHRZ TL outcomes derived using the traditional model and modified approaches using smaller HR zones. HR responses were monitored in 15 semi-professional basketball players during preparatory training to calculate SHRZ TL using the traditional approach with 10%HR_max zones (SHRZ₁₀) and modified approaches with 5%HR_max zones (SHRZ₅) and 2.5%HR_max zones (SHRZ_2.5). Significant (P < 0.001) differences were evident in SHRZ TL between SHRZ₁₀ (254.2 ± 41.7 AU) and SHRZ₅ (275.9 ± 43.3 AU, unclear, small) as well as SHRZ_2.5 (286.7 ± 44.3 AU, very likely, moderate). Use of SHRZ_2.5 provides novel insight regarding internal loading in basketball players and may carry greater sensitivity for detection of maladaptive and adaptive responses to training.  相似文献   

CAT model with personalized algorithm for evaluation of estimated student knowledge     

Svetlana Andjelic  Zoran Cekerevac 《Education and Information Technologies》2014,19(1):173-191

This article presents the original model of the computer adaptive testing and grade formation, based on scientifically recognized theories. The base of the model is a personalized algorithm for selection of questions depending on the accuracy of the answer to the previous question. The test is divided into three basic levels of difficulty, and the student automatically goes from one level to another according to the current level of the knowledge that he shows. Such examination creates an image to the student that the test was set up just for his level of knowledge. On the basis of responses, by applying Bayes’ theorem and the Maximum a posteriori approach, the evaluation grade is formed. In fact, based on empirical probability values, which correlate with obtaining of a certain final grade and the accuracy of answers to each question individually, model creates a score that corresponds to the current level of student’s knowledge. After each test answer, the empirical probability value is updated. That further contributes to the statistical stability of the evaluation model. Testing stops when the student answers the minimum number of questions, determined by a teacher, or, when evaluations show a clear convergence towards a single value. The research method and some results of the testing of the hypotheses as well as authors’ conclusions about CAT as a tool for evaluation of students are presented at the end of the article.  相似文献   

Experience of integrating web 2.0 technologies     

Katerina Zdravkova  Mirjana Ivanovi?  Zoran Putnik 《Educational technology research and development : ETR & D》2012,60(2):361-381

Web users in the 21st century are no longer only passive consumers. On a contrary, they are active contributors willing to obtain, share and evolve information. In this paper we report our experience regarding the implementation of Web 2.0 concept in several Computer Ethics related courses jointly conducted at two Universities. These courses have been delivered to undergraduate and graduate students. The paper addresses main deficiencies of traditional E-learning noticed in earlier years and offers an alternative approach based on social media and collaborative creation of joint contents. Each Web 2.0 feature directly implemented in our courses is presented in details. Particular attention is paid to workload, student feedback and to observed benefits and disadvantages.  相似文献

Dribble Deficit: A novel method to measure dribbling speed independent of sprinting speed in basketball players     

Aaron T. Scanlan  Neal Wen  Tania Spiteri  Zoran Milanović  Daniele Conte  Joshua H. Guy 《Journal of sports sciences》2018,36(22):2596-2602

Basketball tests assessing dribbling speed predicated on total performance times are influenced by sprinting speed. This study examines an approach termed Dribble Deficit to counter this limitation by examining the relationships between sprinting and dribbling speed during linear and change-of-direction (COD) tasks measured using total performance time and Dribble Deficit. Ten semi-professional basketball players completed linear sprints and COD sprints with and without dribbling. Dribble Deficit was calculated as the difference between the best time for each dribbling trial and corresponding non-dribbling trial for linear and COD sprints. Large to very large significant relationships (P < 0.05) were evident between linear sprint and dribble times (R = 0.64–0.77, R² = 0.41–0.59), and between COD sprint and dribble times (R = 0.88, R² = 0.77). Conversely, trivial-small relationships were evident between linear sprint time and linear Dribble Deficit (R = 0.01–0.15, R² = 0.00–0.02). A non-significant, moderate, negative relationship was observed between COD sprint time and COD Dribble Deficit (R = ?0.45, R² = 0.20). These findings indicate Dribble Deficit provides a more isolated measure of dribbling speed than tests using total performance times. Basketball practitioners may use Dribble Deficit to measure dribbling speed independent of sprint speed in test batteries.  相似文献   

Development and evaluation of an e-learning course for deaf and hard of hearing based on the advanced Adapted Pedagogical Index method     

Matjaž Debevc  Zoran Stjepanovič  Andreas Holzinger 《Interactive Learning Environments》2013,21(1):35-50

Web-based and adapted e-learning materials provide alternative methods of learning to those used in a traditional classroom. Within the study described in this article, deaf and hard of hearing people used an adaptive e-learning environment to improve their computer literacy. This environment included streaming video with sign language interpreter video and subtitles. The courses were based on the learning management system Moodle, which also includes sign language streaming videos and subtitles. A different approach is required when adapting e-learning courses for the deaf and hard of hearing: new guidelines must be developed concerning the loading and display of video material. This is shown in the example of the e-learning course, ECDL (European Computer Driving Licence). The usability of the e-learning course is analyzed and confirmed using two methods: first, the Software Usability Measurement Inventory (SUMI) evaluation method, and second, the Adapted Pedagogical Index (AdaPI), which was developed as part of this study, and gives an index to measure the pedagogical effectiveness of e-learning courses adapted for people with disabilities. With 116 participants, of whom 22 are deaf or hard of hearing, the e-learning course for the target group has been found suitable and appropriate according to both evaluation methods.  相似文献   

Market orientation in managing relationships with multiple constituencies of Croatian higher education   总被引：1，自引：0，他引：1  

Jurica Pavičić  Nikša Alfirević  Zoran Mihanović 《Higher Education》2009,57(2):191-207

In this paper, market orientation in Croatian higher education (HE) is discussed within the context of stakeholder-oriented management. Drawing on existing studies, the ‘classical’ empirical model, describing the market orientation of generic nonprofit organisations, has been adapted to the contingencies of the Croatian HE sector. Empirical testing of the model, based on primary data drawn from the majority of public institutions of higher learning in the country, reveals inadequate market orientation toward the relevant stakeholders. Although social market orientation currently does not exist in Croatian HE institutions, the empirical results confirm that it might be possible to initiate a ‘virtuous circle’, in which relevant market orientation and stakeholder management practices, directed toward one or other of the stakeholders, simultaneously enhance orientation toward the other stakeholders. Unfortunately, the current situation in HE is not satisfactory, which could hinder the implementation of development of knowledge society in Croatia.

The sweat test (ST) is a cornerstone in the diagnosis of cystic fibrosis (CF), together with newborn screening and genetic testing. However, the performance of the ST can depend on the operator’s skill, so several international guidelines have been published to standardise the ST, but inconsistencies remain. The joint Working Group for ST Standardisation (WG STS) of the Croatian Society of Medical Biochemistry and Laboratory Medicine, in association with cistic fybrosis health professional and the Cistic Fibrosis Centre for Paediatrics and Adults, have issued National Guidelines for the Performance of the Sweat Test in order to ensure consistency in ST performance and accuracy of reported results. Many of the standards were taken from the 2nd Edition of the UK Guidelines for Performance of the ST for the Diagnosis of CF, while others were taken from independent consensus statements from the WG STS based on local ST equipment and practices. The standards cover every step of the ST, from the indications for testing to reporting of results and their interpretation, including the analytical phase and quality control. In addition, National Guidelines include appendices with practical examples in order to aid implementation of the recommendations in routine practice.  相似文献
