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

Adaptive output feedback neural network control of uncertain non-affine systems with unknown control direction     

Mohammad M. Arefi  Jafar Zarei  Hamid R. Karimi 《Journal of The Franklin Institute》2014

This paper deals with the problem of adaptive output feedback neural network controller design for a SISO non-affine nonlinear system. Since in practice all system states are not available in output measurement, an observer is designed to estimate these states. In comparison with the existing approaches, the current method does not require any information about the sign of control gain. In order to handle the unknown sign of the control direction, the Nussbaum-type function is utilized. In order to approximate the unknown nonlinear function, neural network is firstly exploited, and then to compensate the approximation error and external disturbance a robustifying term is employed. The proposed controller is designed based on strict-positive-real (SPR) Lyapunov stability theory to ensure the asymptotic stability of the closed-loop system. Finally, two simulation studies are presented to demonstrate the effectiveness of the developed scheme.  相似文献   

Engendering a culture of thinking in a culture of performativity: the challenge of mediating tensions in the Singaporean educational system     

Mohammad Akshir Ab Kadir 《Cambridge Journal of Education》2017,47(2):227-246

Among the major policies that have been implemented to ensure its continued success, Thinking Schools, Learning Nation (TSLN) has been described as the ‘big bang of educational reforms’ in Singapore. However, while the policy aims to develop critical thinkers in school leavers, the corporatisation of education in the shape of structures such as the school excellence model seems to be at odds with TSLN. This paper argues that these structures unwittingly engender a culture of performativity among schools, marginalising the central outcome of its initiative that entails developing a culture of thinking and thinkers. The tension is further exacerbated by the larger rationalities that have shaped Singapore and the pragmatic and instrumental philosophy which underpins its educational system. The tensions generated by the clash between intended (culture of thinking) and engendered culture (culture of performativity) present the challenge of mediation for the system on its path to realising TSLN.  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   

H∞ dynamic observer-based fuzzy integral sliding mode control with input magnitude and rate constraints     

Zeinab Echreshavi  Mokhtar Shasadeghi  Mohammad Hassan Asemani 《Journal of The Franklin Institute》2021,358(1):575-605

This paper focuses on a systematic constrained fuzzy integral sliding mode controller design for a class of uncertain discrete-time nonlinear systems which can be represented as Takagi-Sugeno (T-S) fuzzy models. The contributions are to consider constraints on the control input amplitude and control input amplitude rate and to extend the existing pole-placement design technique for designing gain matrices of the fuzzy sliding surface. Moreover, a dynamic-gain observer along with ${\mathit{H}}_{\infty }$ performance is proposed for attenuating disturbance, which generalizes the existing results on the Proportional Observer (PO), the Proportional Integral Observer (PIO) and the dynamic observer (DO). Finally, the dynamic-observer-based constrained fuzzy integral sliding mode controller is designed. All the proposed design conditions are represented in terms of LMIs-based ones. The methods are studied for not only single-input single-output (SISO) but also multi-input multi-output (MIMO) systems. In the end, the proposed approaches are evaluated on practical and numerical systems to illustrate the superiority of the proposed control scheme.  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
