The role of English language and international media as agents of cultural globalisation and their impact on identity formation in Kuwait     

Mohammed M. Hasanen  Ali A. Al-Kandari  Hussain Al-Sharoufi 《Globalisation, Societies & Education》2014,12(4):542-563

This study examines the influence of English language usage and international media on the strength of either national or global identity. The regression analysis of 354 responses reveals that individuals who studied at universities that use English as a medium of instruction show significant differences in the extent to which they embrace a global identity. Viewing local (Kuwaiti) television programmes and the use of the Internet predict national identity. This study discusses the social entities that are important factors in mitigating the influence of globalisation on national identity. It concludes that the argument that globalisation and Westernisation are two faces of the same coin is overstated.  相似文献   

Recording soccer players' heart rates during matches     

A Ali  M Farrally 《Journal of sports sciences》1991,9(2):183-189

The aim of this study was to examine the possibility of obtaining information about the heart rate and physiological load imposed on soccer players during a game. The study was conducted on 27 soccer players, 9 each from semi-professional, university and recreational soccer teams. Players from all positions (attack, midfield and defence) were selected for the study. Each subject's heart rate was monitored during a match using a short-range radio telemetry (Sport Tester PE3000), and was sampled at 5-s intervals. The results indicate that it is possible to monitor successfully the heart rate of players with such equipment. The mean heart rate and standard deviation for each player during match play were: semi-professional players (172 +/- 12, 176 +/- 9 and 166 +/- 15 for forwards, midfielders and defenders, respectively); university players (171 +/- 13, 173 +/- 10 and 156 +/- 13 for forwards, midfielders and defenders, respectively); and recreational players (173 +/- 13, 170 +/- 12 and 162 +/- 13 for forwards, midfielders and defenders, respectively). Analysis by playing position revealed that midfield and forward players has a greater mean heart rate during a game than defensive players. To examine the suitability and accuracy of the two methods of obtaining objective data on heart rate, comparisons were made between the Sport Tester PE3000 and a standard electrocardiograph (ECG) telemetry technique. The results show that both techniques produce similar results; the former was the more convenient.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献   

Examining the antecedents of e-loyalty intention in an online reservation environment     

Samar Mouakket  Mohammad Ahmad Al-hawari 《The Journal of High Technology Management Research》2012,23(1):46-57

Online reservation has increased significantly in recent years. Understanding how customers behave towards this technology is considered to be important to interested parties, such as travel agencies and tourism marketing managers, in order to enable them to improve their marketing strategies, which would, in turn, allow them to retain their customers. This paper presents findings about the antecedents of e-loyalty intention towards online reservation among 288 respondents in the United Arab Emirates. The research examines the role of e-service quality, hedonic and utilitarian values, satisfaction, and subjective norms in motivating loyalty intention towards online reservation. The results show that e-service quality has a significant influence on hedonic and utilitarian values, which, in turn, affect customer satisfaction. Moreover, satisfaction and subjective norms positively affect e-loyalty intention towards online reservation.  相似文献   

Microfluidic impedance spectroscopy as a tool for quantitative biology and biotechnology     

Ahmet C. Sabuncu  Jie Zhuang  Juergen F. Kolb  Ali Beskok 《Biomicrofluidics》2012,6(3)

A microfluidic device that is able to perform dielectric spectroscopy is developed. The device consists of a measurement chamber that is 250 μm thick and 750 μm in radius. Around 1000 cells fit inside the chamber assuming average quantities for cell radius and volume fraction. This number is about 1000 folds lower than the capacity of conventional fixtures. A T-cell leukemia cell line Jurkat is tested using the microfluidic device. Measurements of deionized water and salt solutions are utilized to determine parasitic effects and geometric capacitance of the device. Physical models, including Maxwell-Wagner mixture and double shell models, are used to derive quantities for sub-cellular units. Clausius-Mossotti factor of Jurkat cells is extracted from the impedance spectrum. Effects of cellular heterogeneity are discussed and parameterized. Jurkat cells are also tested with a time domain reflectometry system for verification of the microfluidic device. Results indicate good agreement of values obtained with both techniques. The device can be used as a unique cell diagnostic tool to yield information on sub-cellular units.  相似文献   

An interdisciplinary overview and intelligent control of human prosthetic eye movements system for the emotional support by a huggable pet-type robot from a biomechatronical viewpoint     

Faezeh Farivar  Mahdi Aliyari Shoorehdeli  Mohammad Teshnehlab 《Journal of The Franklin Institute》2012,349(7):2243-2267

Despite active research and significant progress in the last three decades on control of human eye movements, it remains challenging issue due to its applications in prosthetic eyes and robotics. Till now, no considerable investigation of this subject is presented in the interdisciplinary sciences. The goal of this paper is to present a distinguished survey of existing literature on the intelligent control of the human eye movements system applied in a huggable pet-type robot as a biomechatronic system.In this study, the basic knowledge of human eye movements control is explained to show how the neural networks in the brainstem control the human eye movements. The geometry and model of human eye movements system are investigated and this system is considered as a nonlinear control system. The specified model may only be an academic exercise. It can have scientific importance in understanding of the human movement system in general. Also, it can be useful for robotics.Intelligent methods such as artificial neural networks and fuzzy neural networks are proposed to control the human eye movements and numerical simulations are presented. It is discussed that the intelligent controls applied to control of human eye movements system are emulated from the neural controls in biological system.  相似文献

Growth and yield of rice as affected by transplanting dates and seedlings per hill under high temperature of Dera Ismail Khan, Pakistan     

Baloch MS  Awan IU  Hassan G 《Journal of Zhejiang University. Science. B》2006,7(7):572-579

Studies were initiated for two consecutive years to find out the effect of time of transplanting and seedlings hill^-l on the productivity of rice in Dera Ismail Khan district of North West Frontier Province （NWFP）, Pakistan. The experiment was laid out in a randomized complete block design with split plot arrangements. Main plots consisted of four transplanting dates viz. 20th and 27th of June and 4th and 1 lth of July while sub-plots contained 1, 2, 3 or 4 seedlings hill^-1. Among transplanting dates, June 20th planted crop gave highest paddy yield and net return with I seedling hill^-1. It explains that the use of more seedlings hill^-1 not only adds to cost but is also a mere wastage of natural resources. Based on research findings, we conclude that the use of I seedling hill^-1 is most appropriate for timely sowing otherwise 4 seedlings hill^-1 should be used to compensate for the yield gap in late transplanted rice.  相似文献   

Allies in learning: critical insights into the importance of staff–student interactions in university education     

Sarah Richardson  Ali Radloff 《Teaching in Higher Education》2013,18(6):603-615

Discussions of the quality of learning in university education often focus on curricula. Less attention is paid to the role of student–staff interactions. In a context in which a host of factors place pressure on the opportunities for students and staff to interact, it is important to use empirical insights to inform decisions about how to optimise learning. This paper uses data from a large survey of students and teaching staff in Australia to suggest that students and staff should be regarded as allies in learning. It investigates student reports to suggest that frequent interactions with those who teach them lead to higher levels of student engagement and satisfaction and lower attrition rates. The advantages do not only flow in one direction. Teaching staff gain insights into students' learning experiences, providing them with clues to better target their teaching.  相似文献   

Students' perception of university teaching behaviours     

Akhtar Ali  Riaz H. Tariq  J. Topping 《Teaching in Higher Education》2013,18(6):631-647

The purpose of the paper is to explore Students' perception of university teaching behaviours in Pakistan. Three hundred and fifty students from the six public sector Pakistani universities returned questionnaires. Assessment framework, learning activities and instructional strategies emerged from factor analysis as common factors. Students' views on five conceptual variables were also analysed: instructional design, active teaching, learning activities, questioning styles; and assessment framework. University teaching in Pakistan was found to be driven by assessment. This is a matter of concern for all stake holders, including the administration of the universities, teachers, students and the Higher Education Commission. A teaching behaviour paradigm shift is required, switching from knowledge-oriented teaching behaviour focused on successful passage through assessment, to teaching behaviour focused upon the development of transferable skills demanded by external markets.  相似文献
