E-government involves the use of information and communications technology to facilitate government interaction with citizens, employees, businesses and other governments. E-government studies provide a platform to examine prior developments, and explore future opportunities in the field. This paper presents a theoretical model for the analysis of e-government studies and further uses a bibliometric analysis to examine constructs such as theoretical perspectives, methods, and units of analyses. We examine current trends in e-government research, and discuss emerging opportunities. 相似文献

This article proposes an approach to media imperialism from the telegraphic news agencies’ point of view. Since the mid-nineteenth century, in fact, Western imperial interests were reflected in the geographical expansion led by the first international news agencies. The War of the Pacific (1879–83) in South America provides an entry point for investigating both the notion of the British ‘informal empire’ and the role of the first telegraphic news agencies in the South American region. The history of the news agency business in the subcontinent from the 1850s onwards helps contextualize the conflict between the South American republics of Bolivia, Chile and Peru as news agencies, newspapers and other information practices of the time revealed this event in Europe and the rest of the world. By the end of the war, Reuters and Havas (the British and the French news agencies), numbered their own casualties as a consequence of their confrontation in an extra-European region. 相似文献

以SD大鼠为实验动物,通过8 w的高能饲料摄入和4 w的运动锻炼后,检测其血清总蛋白、白蛋白含量,外周血CD3 细胞数量、CD4 、CD8 T细胞百分比的变化,来研究适度运动锻炼对高能饲料摄入动物免疫功能的影响。结果显示:适度运动锻炼明显提高CD3 T细胞数量,使CD4 T细胞百分比从55.2%-56.6%迅速上升到62.6%-63.0%,使高能饲料摄入组的CD8 T细胞百分比从56.2%极显著地下降到42.2%,从而使运动组的CD4 /CD8 的比值(1.49±0.10)显著高于对照组(1.01±0.07),表明适度运动锻炼具有显著促进正相免疫调节的作用。 相似文献

Advanced clinical practice roles are now an integral feature of many healthcare services and have been adopted in a diversity of areas. However, mentoring of these roles is not well documented in the literature and formal mechanisms of support are limited. An action learning set (ALS) was developed to provide support for consultants currently in post. The purpose was to facilitate clinicians in developing and meeting the demands of these posts by providing peer supervision, identifying strategies for leading service developments, providing a focus for problem solving and reflection. The ALS meets bi-monthly and is externally facilitated with the option to attend individual sessions with the facilitator. Participants also completed questionnaires measuring coping skills and stress, which were fed back in the individual sessions, providing opportunity for further opportunities for reflection. Initial evaluation was conducted formally using a structured questionnaire and reflective accounts, and provided evidence of the value of the ALS and an indication of how the criteria for success were being met, with greatest achievement reported in the area of work–life balance. The evaluation demonstrates the ongoing value of this ALS and the effectiveness of this method of supporting senior clinical staff. 相似文献

This study used qualitative and quantitative approaches to evaluate the effectiveness of self‐learning modules (SLMs) developed to facilitate and individualize students' learning of basic medical sciences. Twenty physiology and nineteen microanatomy SLMs were designed with interactive images, animations, narrations, and self‐assessments. Of 41 medical students, 40 students voluntarily completed a questionnaire with open‐ended and closed‐ended items to evaluate students' attitudes and perspectives on the learning value of SLMs. Closed‐ended items were assessed on a five‐point Likert scale (5 = high score) and the data were expressed as mean ± standard deviation. Open‐ended questions further evaluated students' perspectives on the effectiveness of SLMs; student responses to open‐ended questions were analyzed to identify shared patterns or themes in their experience using SLMs. The results of the midterm examination were also analyzed to compare student performance on items related to SLMs and traditional sessions. Students positively evaluated their experience using the SLMs with an overall mean score of 4.25 (SD ± 0.84). Most students (97%) indicated that the SLMs improved understanding and facilitated learning basic science concepts. SLMs were reported to allow learner control, to help in preparation for subsequent in‐class discussion, and to improve understanding and retention. A significant difference in students' performance was observed when comparing SLM‐related items with non‐SLM items in the midterm examination (P < 0.05). In conclusion, the use of SLMs in an integrated basic science curriculum has the potential to individualize the teaching and improve the learning of basic sciences.

Along with the significant development of information and communication technologies (ICTSs), an incredible number of mobile applications have become available. Hence, the main purpose of the current study is to investigate the use and acceptance of the ‘Mobile Information System’ developed and implemented by University of Jordan, which Known as (Mobile Student Information System). Data were obtained from 275 undergraduate students of University of Jordan via questionnaire to test the ‘Mobile Services Acceptance Model’ using Structural Equation Model. The results reveal that user acceptance of mobile information system services is largely affected by trust, perceived security, perceived ease of use and perceived usefulness. Findings also show that context of applications is a strong motivational factor of perceived ease of use and perceived usefulness, which then significantly affects user intention to use mobile information system. While, the personal characteristics and features do not have effect on user intentions. Both theoretical and practical implications of the study’s findings are discussed. 相似文献

The purpose of this paper is to report the findings of a study of publishing behaviour among a group of Arab scholars in social science and humanities disciplines. The paper also investigated the number of Arab scholars who are publishing in predatory journals and the reasons that drive them to select these journals to share their scholarly findings. The study adopted a mixed methods approach. Eighteen journals that were categorized as predatory journals were scanned to find the number of Arab scholars who published in them. Then, a questionnaire was sent to Egyptian and Saudi scholars as they were found to be the top Arab contributors in these journals. The questionnaire was followed by semi‐structured interviews to gain an in‐depth understanding of the publishing behaviour. The data showed that many Arab scholars prefer publishing in predatory journals as these journals are easier and faster. The results also indicate that there is a need to raise the awareness of the harm that predatory journals can cause to the scholars and how they can avoid these journals. This study was conducted with social science and humanities scholars in Egypt and Saudi Arabia. The publishing behaviour may differ in other scholarly disciplines and other Arabic countries. 相似文献
