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

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

Contrary to the common belief of Arabic language users that the Arabic writing system has descenders as an inherent quality, some historical examples demonstrate that there were some artistic attempts to create non-descender, all-cap calligraphic systems, but they have never been studied as a phenomenon. This article draws attention to the existence of these examples, and analyses and classifies them according to their form.

The article begins with an analysis of the current Arabic writing system in terms of descenders, differentiating between artistic and functional writing, defining the need for harmonious balance in artistic writing, and demonstrating that descenders do disrupt the balance in Arabic writing, which could be considered as an ascender-system.

Then, historical examples of the non-descender system are introduced, categorised into four visual stages, and the descender handling for each stage is described; all-capital letter examples are then introduced.

Finally, some historical texts describing the beauty of calligraphy in this specific system of writing are analysed.

Whether screening tests or teacher ratings best predict children at risk for reading failure continues to be an area of disagreement in the early identification literature. Our early studies confirmed low positive identification rates (30%) when kindergarten teachers were asked to predict future reading achievement using a traditional rating scale, while a project-developed, theory-based screening battery correctly identified 81% of poor readers. Construction of a teacher rating scale of current skill levels on research-validated precursors to reading improved prediction in the current study, although results were still inferior to the screening test (64% and 80% valid positives, respectively). Combining test results and teacher ratings resulted in 88% identification of those who failed in first, second, or third grade, suggesting that both teacher ratings and screening tests should be used to identify the largest number of those who will later fail in reading. © 1998 John Wiley & Sons, Inc.  相似文献

Abstract

Cross‐border informal trade is one of the most important issues between India and Bangladesh. It takes place between people who live a short distance apart, but who find themselves separated by an international boundary. The people of international border areas believe that cross‐border informal trade is a process to maintain a sustainable livelihood because it provides a livelihood to the unemployed. This research has analysed the nature and impact of informal border trade between India and Bangladesh. It has highlighted the sources of security and insecurity through the process of informal border trade. It also analyses the different socio‐economic conditions of informal border trade in border trade prone areas. This research argues that although informal border trade is considered illegal, it is necessary for the maintenance of the livelihood for the poor in the bordering areas. The state failures in fulfilling the needs of the poor force them to involve themselves in informal border trade.  相似文献

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

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

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

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
