The study of the success indicators for pre-implementation activities of Iran's E-Government development projects     

Mohammad Sharifi  Amir Manian 《Government Information Quarterly》2010

E-Government and E-Government development project studies have been conducted in most industrialized societies, as well as in Iran. Due to their nature and structure, E-Government development projects have numerous political, social, and economic impacts on society. Given the incorporation of significant capital, human resources, information, and political commitments, these projects are considered quite vital to society. Following the systematic pre-implementation activities of E-Government development projects is critical for the success of such projects; ignoring such issues leads to various problems during E-Government project implementation. This research aims to explore and detect the success indicators for pre-implementation activities of E-Government development projects, evaluate the validity of these indicators, and investigate the indicators' status in the Fuel Smart Card Project. The researcher has also provided some suggestions on the successful implementation of E-Government development projects.  相似文献   

Identification of cement rotary kiln using hierarchical wavelet fuzzy inference system     

A. Sharifi  M. Aliyari Shoorehdeli  M. Teshnehlab 《Journal of The Franklin Institute》2012,349(1):162-183

Rotary kiln is the central and the most complex component of cement production process. It is used to convert calcineous raw meal into cement clinkers, which plays a key role in quality and quantity of the final produced cement. This system has complex nonlinear dynamic equations that have not been completely worked out yet. In conventional modeling procedure, a large number of the involved parameters are crossed out and an approximation model is presented instead. Therefore, the performance of the obtained model is very important and an inaccurate model may cause many problems for designing a controller. This study presents hierarchical wavelet TS-type fuzzy inference system (HWFIS) for identification of cement rotary kiln. In the proposed method, wavelet fuzzy inference system (WFIS) with two input variables is used as sub-model in a hierarchical structure and gradient descent (GD) algorithm is chosen for training parameters of antecedent and conclusion parts of sub-models. The results show that the proposed method has higher performance in comparison with the other models. The data collected from Saveh White Cement Company is used in our simulations.  相似文献   

Hydro-Alcoholic Cinnamon Extract, Enhances Glucose Transporter Isotype-4 Translocation from Intracellular Compartments into the Cytoplasmic Membrane of C2C12 Myotubes     

Abdorrahim Absalan  Javad Mohiti-Ardakani  Hossein Hadinedoushan  Mohammad Ali Khalili 《Indian journal of clinical biochemistry : IJCB》2012,27(4):351-356

Cinnamon has been used as an anti-diabetic agent for centuries but only in recent few years its mechanism of action has been under investigation. Previous studies showed that cinnamon might exert its anti-diabetic effect via increasing glucose transporter isotype-4 (GLUT4) gene and glycoprotein contents in fat cells. To study if hydro-alcoholic cinnamon extract (HACE) enhances GLUT4 translocation from intracellular compartments of nuclear or endoplasmic reticulum membranes (N/ER) into the cytoplasmic membrane (CM). C2C12 myoblastic cell line were seeded in DMEM plus 20 % FBS and differentiated to myotubes using 2 % horse serum. After myotubes formation, 100 or 1,000 μg/ml HACE, as intervention, and as control 1 % DMSO were added for 3 h. Cells were washed and homogenized followed by ultracentrifuge fractionation, protein separation by SDS-PAGE and GLUT4 detection using semi-quantitative Western blotting. Data analysis was done by two-independent samples t test for comparison of mean ± SD of GLUT4 percent in categories. GLUT4 contents were higher in CM of groups 100 and 1,000 μg/ml HACE and lower in 1 % DMSO treated myotubes (CI = 0.95, P < 0.05). For N/ER reverse results were obtained (CI = 0.95, P < 0.05). As our results have shown HACE induces GLUT4 translocation from intra-cell into cell surface. We conclude that cinnamon maybe a choice of type-2 diabetes mellitus treatment because its extract enhances GLUT4 contents in CM where it facilitates glucose entrance into the cell. However it is necessary to trace the signaling pathways which are activated by HACE in muscular tissue.  相似文献   

Computerization and e-Government implementation in Jordan: Challenges, obstacles and successes     

Eman  Mohammad   《Government Information Quarterly》2009,26(4):577-583

With the latest revolution of technology in information, communications, and media, the need for computerization has been identified in most countries. Many social and technical advantages and problems come along with it. As a result, the Information Society concept has been created. There exist certain principles for building such a society, but in Arab regions it has unique challenges and obstacles. Jordan, responding to a royal vision, has established the goal of becoming a leader in information and economic developments among other countries in the region. Several plans and initiatives have been developed for this purpose. One of these initiatives is the implementation of e-Government, which offers several benefits for both the government and society. e-Government has five building blocks to achieve the expected results and the process of implementation involves passing through certain stages. Jordan, as an Arab country, faces several obstacles in the area of implementation. A readiness study for Jordan has been accomplished and implementation and achievements have been made in Jordanian e-Government.  相似文献   

Research Productivity and Social Capital in Australian Higher Education     

Mohammad Salaran 《Higher Education Quarterly》2010,64(2):133-148

This study investigates the role of social capital in raising research productivity in academic institutions. Social capital as a strategic resource embedded in social relationships can be utilised towards decreasing pressures from external environmental conditions, such as the global financial crisis. A survey was sent to academic staff in five universities in Victoria, to collect data regarding their frequency of communications and research productivity. The findings indicated that there is a significant and positive correlation between social interactions and research productivity. Regression analysis demonstrated that social interactions as an independent variable predict research productivity of academics.  相似文献

Written for teachers, who generally lack a sufficient knowledge of how people learn, Pritchard's book aims at enhancing the effectiveness and efficiency of education through raising teachers' understanding of learning theory. However, it does not do so very effectively: even if you are a keen teacher, you will probably find only parts of much interest or use. Mohammad Ali Salmani Nodoushan  相似文献   

Who Pays for Online Content? A Media Dependency Perspective Comparing Young and Older People     

Liu Yang  Louisa Ha  Fang Wang  Mohammad Abuljadail 《媒体管理杂志》2015,17(4):277-294

This study examines predictors of online content purchases through media dependency theory and comparing young and older people. It focuses on actual online content purchases instead of willingness-to-pay used in previous studies. The effects of two dimensions of media dependencies are compared: intensity and referent scopes. Social media dependency and mobile media dependency are examined specifically, in addition to general Internet dependency as new media dependency. Our results show young people make more actual purchases of online content than older people. Predictors of online content purchases include age group, online shopping habits, ownership of mobile applications and mobile devices, Internet referent dependency, and social media intensity dependency. New media referent dependency is more important than intensity dependency for predicting online content purchases.  相似文献   

Partisan Media and Discussion as Enhancers of the Belief Gap     

Aaron S. Veenstra  Mohammad Delwar Hossain  Benjamin A. Lyons 《Mass Communication and Society》2014,17(6):874-897

This study examines the roles of partisanship, partisan media use, and political discussion in the development of belief gaps. Using national survey data, we construct models of political identity, media use, and discussion factors predicting beliefs on five contested political issues and find that ideology and partisanship are generally stronger predictors of beliefs than is education. Notably, each has independent effects on belief outcomes. Contrary to some concerns that the Internet especially promotes partisan clustering, use of partisan traditional media—television and radio—is by far the strongest information-related predictor of belief outcomes, whereas partisan social media use and partisan discussion are relatively weak and inconsistent. These findings suggest that political elites continue to exert significant influence over the perceptions of rank and file partisans.  相似文献   

Personalized recommendation of learning material using sequential pattern mining and attribute based collaborative filtering     

Mojtaba Salehi  Isa Nakhai Kamalabadi  Mohammad Bagher Ghaznavi Ghoushchi 《Education and Information Technologies》2014,19(4):713-735

Material recommender system is a significant part of e-learning systems for personalization and recommendation of appropriate materials to learners. However, in the existing recommendation algorithms, dynamic interests and multi-preference of learners and multidimensional-attribute of materials are not fully considered simultaneously. Moreover, these algorithms cannot effectively use the learner’s historical sequential patterns of material accessing in recommendation. For addressing these problems and improving the accuracy and quality of recommendation, a new material recommender system framework based on sequential pattern mining and multidimensional attribute-based collaborative filtering (CF) is proposed. In the sequential pattern based approach, modified Apriori and PrefixSpan algorithms are implemented to discover latent patterns in accessing of materials and use them for recommendation. Leaner Preference Tree (LPT) is introduced to take into account multidimensional-attribute of materials, and learners’ rating and model dynamic and multi-preference of learners in the multidimensional attribute-based CF approach. Finally, the recommendation results of two approaches are combined using cascade, weighted and mixed methods. The proposed method outperforms the previous algorithms on the classification accuracy measures and the learner’s real learning preference can be satisfied accurately according to the real-time up dated contextual information.  相似文献   

Challenges and policies for promoting internationalization—The case of Iranian public universities     

Mohammad Moshtari  Sorour Delbakhsh  Maryam Ghorbani 《Higher Education Quarterly》2023,77(4):585-601

The global knowledge economy has turned higher education into a key player in societal development. Internationalization benefits higher education institutions in several aspects, such as improvement and visibility in international rankings, revenue generation via tuition fees and external funding, improvement of research and teaching quality, integration with academic communities and familiarization with scholarly attitudes. In this study, we provide insights into the challenges of internationalization faced by higher education institutions in Iran as a developing country. Several policies and practices have been adopted in Iran to improve internationalization efforts; however, these activities have had little impact on the quality of research and educational programs at Iran's universities. Understanding the challenges they face in a systematic way can help identify different factors and develop a set of suggestions to increase the quality and quantity of international cooperation. We formulate our suggestions based on the opportunities provided by the digitalization solutions in the aftermath of the COVID-19 pandemic and the increasing importance of the UN's Sustainable Development Goals in both global and national environments. We interviewed 15 faculty members in Iranian higher education institutions and 14 managers in charge of international affairs at universities in Iran. In addition, data extracted from three forums on Iranian higher education internationalization are analysed. Using a grounded theory approach, we group the challenges into macro-, institutional and individual levels and then suggest a number of practices and policies to increase the quantity and quality of internationalization efforts.  相似文献
