E-Government adoption and implementation has gained noticeable momentum across many developed and developing economies. Nevertheless, transitioning from the “electronic” to the stage of “transformational” domain – coined as t-Government – is posing the greatest challenge of how government services respond to changes in the broader economy and society. Despite considerable investments and the wide use of Information and Communications Technology (ICT), research literature on e-Government suggests that government services have yet to reach the full potential of seamless integration, where all transactions are completed electronically. Through a detailed analysis of the extant e-Government literature and a case study based empirical research, this paper explores the domain of e-Government in identifying the possible reasons for this potential shortfall in achieving full integration. Furthermore, the paper intends to highlight an aspect of complexity surrounding crossing the integration gap as the authors denote by “eChasm” in the e-Government conceptual model that leads to transformation. In addition, it focuses on radical change through Business Process Re-engineering (BPR) and the call for strategic style of leadership, for cross-agency collaboration leading to a successful realisation of transformational government (t-Government). It is interesting to note that researchers and public sector leaders have started to realise that implementing and managing the transformation of public services, copiously satisfying the users and stakeholders, is a task of multi-dimensional complexity.  相似文献   

Extraction of DNA suitable for PCR applications from mature leaves of Mangifera indica L.     

Muhammad Abubakkar Azmat  Iqrar Ahmad Khan  Hafiza Masooma Naseer Cheema  Ishtiaq Ahmad Rajwana  Ahmad Sattar Khan  Asif Ali Khan 《Journal of Zhejiang University. Science. B》2012,13(4):239-243

Good quality deoxyribonucleic acid (DNA) is the pre-requisite for its downstream applications. The presence of high concentrations of polysaccharides, polyphenols, proteins, and other secondary me- tabolites in mango leaves poses problem in getting good quality DNA fit for polymerase chain reaction (PCR) applications. The problem is exacerbated when DNA is extracted from mature mango leaves. A reliable and modified protocol based on the cetyl- trimethylammonium bromide (CTAB) method for DNA extraction from mature mango leaves is described here. High concentrations of inert salt were used to remove polysaccharides; Polyvinylpyrrolidone (PVP) and β-mercaptoethanol were employed to manage phenolic compounds. Extended chloroform-isoamyl alcohol treatment followed by RNase treatment yielded 950?1050 μg of good quality DNA, free of protein and RNA. The problems of DNA degradation,contamination, and low yield due to irreversible binding of phenolic compounds and coprecipitation of polysaccharides with DNA were avoided by this method. The DNA isolated by the modified method showed good PCR amplification using simple se- quence repeat (SSR) primers. This modified protocol can also be used to extract DNA from other woody plants having similar problems.  相似文献

Swayed by the logo and name: does university branding work?     

Muhammad Zaffwan Idris 《Journal of Marketing for HIGHER EDUCATION》2014,24(1):41-58

Over the last decade, many universities attempted to improve their public image by changing their corporate visual identity (CVI) and/or name. Despite the prevalence of such practices, little research has been conducted into their effectiveness. The research reported here focused upon one facet of the higher education branding debate, that of the effectiveness of CVI in influencing observers' perceptions of a university and, by association, its lecturers. A secondary question concerned the name. Photographs of two lecturers (M/F) were placed into controlled digital simulations of a university foyer featuring systematically varied CVI and name. Using a range of measures and a large-sample Internet survey of n?=?888, we found that CVI and name affected respondents' perceptions of university lecturers. However, the enhancement was exclusively upon perceptions of the male lecturer, and strongly favored traditional, heraldic CVI, with a secondary naming effect.  相似文献   

Microbial control of diamondback moth, Plutella xylostella L.(Lepidoptera: Yponomeutidae) using bacteria (Xenorhabdus nematophila) and its metabolites from the entomopathogenic nematode Steinernema carpocapsae

Cells and cell-free solutions of the culture filtrate of the bacterial symbiont, Xenorhabdus nematophila taken from the entomopathogenic nematode Steinernema carpocapsae in aqueous broth suspensions were lethal to larvae of the diamondback moth Plutella xylostella. Their application on leaves of Chinese cabbage indicated that the cells can penetrate into the insects in the absence of the nematode vector. Cell-free solutions containing metabolites were also proved as effective as bacterial cells suspension. The application of aqueous suspensions of cells of X. nematophila or solutions containing its toxic metabolites to the leaves represents a possible new strategy for controlling insect pests on foliage.  相似文献   

Additive effects due to biochar and endophyte application enable soybean to enhance nutrient uptake and modulate nutritional parameters     

Muhammad Waqas  Yoon-Ha Kim  Abdul Latif Khan  Raheem Shahzad  Sajjad Asaf  Muhammad Hamayun  Sang-Mo Kang  Muhammad Aaqil Khan  In-Jung Lee 《Journal of Zhejiang University. Science. B》2017,18(2):109-124

We studied the effects of hardwood-derived biochar (BC) and the phytohormone-producing endophyte Galactomyces geotrichum WLL1 in soybean (Glycine max (L.) Merr.) with respect to basic, macro- and micronutrient uptakes and assimilations, and their subsequent effects on the regulation of functional amino acids, isoflavones, fatty acid composition, total sugar contents, total phenolic contents, and 1,1-diphenyl-2-picrylhydrazyl (DPPH)-scavenging activity. The assimilation of basic nutrients such as nitrogen was up-regulated, leaving carbon, oxygen, and hydrogen unaffected in BC+G. geotrichum-treated soybean plants. In comparison, the uptakes of macro- and micronutrients fluctuated in the individual or co-application of BC and G. geotrichum in soybean plant organs and rhizospheric substrate. Moreover, the same attribute was recorded for the regulation of functional amino acids, isoflavones, fatty acid composition, total sugar contents, total phenolic contents, and DPPH-scavenging activity. Collectively, these results showed that BC+G. geotrichum-treated soybean yielded better results than did the plants treated with individual applications. It was concluded that BC is an additional nutriment source and that the G. geotrichum acts as a plant biostimulating source and the effects of both are additive towards plant growth promotion. Strategies involving the incorporation of BC and endophytic symbiosis may help achieve eco-friendly agricultural production, thus reducing the excessive use of chemical agents.  相似文献   

Establishment of engineering laboratories for undergraduate and postgraduate studies     

Wasim Ahmed Khan  Saad Muhammad Rasheed Al-Doussari  A. H. M. Al-Kahtani 《European Journal of Engineering Education》2002,27(4):425-435

The importance of the laboratories for the study of engineering problems is manifold. At the undergraduate level it provides an opportunity for the students to get an impression of the basic principles of engineering. At the postgraduate level it becomes an instrument for advanced level study and for the solutions to real-life engineering problems. Level of emphasis by an individual engineering institution on basic engineering, interdisciplinary aspects of engineering and relevance to international, national and local industrial trends effects the policy to establish the engineering laboratories. However, a core facility, for the teaching of the most basic principals of relevant field of engineering should be a common feature of all the laboratories associated with individual subject area. In this research paper an approach for establishing engineering laboratories is presented. It discusses the relation between the syllabus of appropriate level of study and the equipment required in the laboratory, physical planning for the laboratory, sequential and parallel approaches for establishing the laboratories, the functional capacity of laboratories, the organizational flexibility of the laboratories, the cost factor and the recurring expenditure. It suggests ways of utilizing the laboratory for effective teaching and research through optimal use of the above factors.  相似文献

INTRODUCTION Rice (Oryza sativa L.) is one of the most im-portant crops in Pakistan. It is the third largest crop interms of area and production after wheat and cotton.Although rice in Pakistan is consuming large acreage,Pakistan is still far behind other rice producingcountries. The average yield is very low (2 t/ha) ascompared to Egypt (8.4 t/ha) and USA (6.6 t/ha).There are many reasons for this low yield. The mostimportant are high temperature (40?50 °C), low hu-midity at …  相似文献   

What is an objective structured practical examination in anatomy?     

Ahmed Yaqinuddin  Muhammad Zafar  Muhammad Faisal Ikram  Paul Ganguly 《Anatomical sciences education》2013,6(2):125-133

Assessing teaching‐learning outcomes in anatomical knowledge is a complex task that requires the evaluation of multiple domains: theoretical, practical, and clinical knowledge. In general, theoretical knowledge is tested by a written examination system constituted by multiple choice questions (MCQs) and/or short answer questions (SAQ). The assessment of practical knowledge (three‐dimensional anatomical concepts) involves oral, spot, or objective structured practical examinations (OSPE). Finally, the application of anatomical knowledge to patients is tested mainly through objective structured clinical examinations (OSCE). The major focus of this study is the OSPE. Although many schools challenge students using this tool in practical examinations in the early phase of the curriculum, the true meaning of OSPE is frequently forgotten and it becomes, in reality, a spot examination. This article, for the first time, describes how the concept of the OSPE has evolved and is currently being used to assess the practical domain of anatomical knowledge in a problem‐based curriculum at Alfaisal University College of Medicine. In addition, it describes the main differences from the spot examination, which is normally used in traditional medical curricula. The authors believe that the OSPE remains the most efficient tool to assess the practical aspects of anatomical knowledge in a system where basic knowledge is integrated with the clinical or functional part of anatomy. However, this contention only holds true if the OSPE process revolves around structured objectives. Anat Sci Educ 6: 125–133. © 2012 American Association of Anatomists.  相似文献
