This book combines cultural models with practice‐based learning to develop a new theory of cultural learning. Drawing on insights from anthropology, it argues how collective and social cultures can emerge from an “engaged” learning process. The book opens a new window on human learning; however, you will probably find only parts of it of some interest or use. Mohammad Ali Salmani Nodoushan  相似文献

Finite-time tracking using sliding mode control     

Masood Ghasemi  Sergey G. Nersesov  Garrett Clayton 《Journal of The Franklin Institute》2014

Finite-time stability involves dynamical systems whose trajectories converge to an equilibrium state in finite time. In this paper, we consider a general class of fully actuated mechanical systems described by Euler–Lagrange dynamics and the class of underactuated systems represented by mobile robot dynamics that are required to reach and maintain the desired trajectory in finite time. An approach known as the terminal sliding mode control (TSMC) involves non-smooth sliding surfaces such that, while on the sliding surface, the error states converge to the origin in finite time thus ensuring finite-time tracking. The main advantage of this control scheme is in fast converging times without excessive control effort. Such controllers are known to have singularities in some parts of the state space and, in this paper, we propose a method of partitioning the state space into two regions where the TSMC is bounded and its complement. We show that the region of bounded TSMC is invariant and design an auxiliary sliding mode controller predicated on linear smooth sliding surface for the initial conditions outside this region. Furthermore, we extend these results to address TSMC for underactuated systems characterized by the mobile robot dynamics. We demonstrate the efficacy of our approach by implementing it for a scenario when multiple dynamic agents are required to move in a fixed formation with respect to the formation leader. Finally, we validate our results experimentally using a wheeled mobile robot platform.  相似文献   

Team learning in IT implementation projects: Antecedents and consequences     

Ali E. Akgün  Gary S. Lynn  Halit Keskin  Derya Dogan 《International Journal of Information Management》2014

This study investigates the antecedents and consequences of team learning, which is composed of information acquisition, dissemination, and implementation, in information technology (IT) implementation projects. By investigating 129 IT implementation project teams, we found that (1) information acquisition and information dissemination have a positive impact on project outcomes, such as speed-to-users, lower implementation cost, and operational effectiveness, and (2) team behavior and enabler variables, such as teamwork, team communication, interpersonal trust between team members, team commitment, and senior manager support, positively influence team learning. We also found that team anxiety moderates the relationship between team learning and project outcomes.  相似文献

目的:探讨射击运动员目标取向、竞赛状态焦虑的特点及二者之间的关系.方法:采用射击运动员目标取向测验和竞赛状态焦虑问卷对国家射击队、辽宁射击队、北京市射击队36名射击运动员进行调查.结果:(1)射击运动员的任务取向显著高于自我取向.国际健将级运动员任务取向显著高于国家健将和国家一级运动员,而自我取向显著低于后两者;(2)射击运动员的状态自信心得分较高.国家一级运动员的认知状态焦虑显著高于国际健将级和国家健将级运动员;国际健将级运动员的躯体状态焦虑显著低于国家一级运动员;国际健将级运动员的状态自信心显著高于国家健将级和国家一级运动员;(3)自我取向高分组的运动员认知状态焦虑更高,状态自信心更低;任务取向高分组的运动员认知和躯体状态焦虑更低,状态自信心更高.(4)自我取向显著正向预测认知状态焦虑,解释率为31.3%;任务取向显著负向预测躯体状态焦虑,解释率为17%;自我取向显著负向预测状态自信心,解释率为27.3%,任务取向显著正向预测状态自信心,解释率为35.5%.结论:运动级别越高的运动员越倾向于任务取向,认知和躯体状态焦虑越低,状态自信心越高.  相似文献   

Examining the moderating effect of individual-level cultural values on users’ acceptance of E-learning in developing countries: a structural equation modeling of an extended technology acceptance model     

Ali Tarhini  Kate Hone  Xiaohui Liu  Takwa Tarhini 《Interactive Learning Environments》2017,25(3):306-328

In this study, we examine the effects of individual-level culture on the adoption and acceptance of e-learning tools by students in Lebanon using a theoretical framework based on the Technology Acceptance Model (TAM). To overcome possible limitations of using TAM in developing countries, we extend TAM to include subjective norms (SN) and quality of work life constructs as additional constructs and a number of cultural variables as moderators. The four cultural dimensions of masculinity/femininity (MF), individualism/collectivism, power distance and uncertainty avoidance were measured at the individual level to enable them to be integrated into the extended TAM as moderators and a research model was developed based on previous literature. To test the hypothesised model, data were collected from 569 undergraduate and postgraduate students using e-learning tools in Lebanon via questionnaire. The collected data were analysed using the structural equation modelling technique in conjunction with multi-group analysis. As hypothesised, the results of the study revealed perceived usefulness (PU), perceived ease of use (PEOU), SN and quality of work life to be significant determinants of students’ behavioural intention (BI) towards e-learning. The empirical results also demonstrated that the relationship between SN and BI was particularly sensitive to differences in individual-cultural values, with significant moderating effects observed for all four of the cultural dimensions studied. Some moderating effects of culture were also found for both PU and PEOU, however, contrary to expectations the effect of quality of work life was not found to be moderated by MF as some previous authors have predicted. The implications of these results to both theory and practice are explored in the paper.  相似文献   

Exploring the use of the ICT in supporting dyslexic students’ preferred learning styles : A preliminary evaluation     

FatimaEzzahra Benmarrakchi  Jamal El Kafi  Ali Elhore  Sara Haie 《Education and Information Technologies》2017,22(6):2939-2957

Dyslexia is one of the most common learning disabilities. It is described as a disorder manifested by difficulty in learning to read despite conventional instruction, adequate intelligence, and sociocultural opportunity. It affects relatively about 7–10 % of the population across most languages and cultures. In this study, we explore the potential benefits offered by the use of Information and Communication Technology (ICT) to support dyslexic students by considering their preferred learning styles. In the current paper we administered the VAK and Honey & Mumford questionnaires to 28 Arabic students with ages between 8 and 10 years old. 8 students from dyslexic group and 20 students from control group were selected to assess and compare their preferred learning style. The implemented system focuses on dyslexia in Arabic language, especially in Arabic countries such as Morocco. Based on the results of the analysis of learning styles differences, we introduced an adaptive mobile learning to support and promote learning for dyslexic students. The aim of the study is to consider the relationship between dyslexia and learning style and to suggest a different learning way. Preliminary results show that the ICT has a valuable role in providing opportunities for learners with dyslexia to participate more fully in education.  相似文献   

The extent of concentration in journal publishing     

Fereshteh DIDEGAH  Ali GAZNI 《Learned Publishing》2011,24(4):303-310

This study examines the extent of concentration in the journal publishing industry. A number of aspects are considered: publishers, journal impacts, countries, and languages. For journals indexed in JCR from 1997 to 2009, just 0.2% of publishers produce 50% of journals and articles, and 0.3% of publishers account for the top 50% of citations, impact factors and immediacy indices. More than a half of publishers in JCR are from four countries: USA, UK, Germany and Japan. In addition, more than a half of journals come from the USA and UK. Examining the publishers' interactions in terms of buying and selling journals shows the extent of change by acquisition, and the acquisition links between publishers. The findings confirm that the international market of journal publishing is essentially dominated by a few publishers.  相似文献
