Fatwa and the internet: a study of the influence of Muslim religious scholars on internet diffusion in Saudi Arabia

This study uses diffusion of innovations theory to examine the influence of Muslim religious scholars on internet diffusion in Saudi Arabia. It applies content analysis to the fatwa, the religious edicts that Muslim religious scholars issue, to explore fatwa decisions relating to the internet since its launch in Saudi Arabia in 1999. There are 34 fatwa in total, 11 with approving decisions, 11 with disapproving ones, and 12 with conditionally approving decisions. Those who issue approving fatwa argue that it helps to spread the word of Allah and that if Muslims do not exploit the opportunities provided by the internet, then non-Muslims and non-believers will use it for evil. To explain their disapproving fatwa, other scholars argue that the internet corrupts people. The study discusses the impact of religion and religious scholars on the dissemination of communication technologies in Saudi society. It also predicts a pattern of opinions that scholars may be expected to adopt on the introduction of any new communication technology that is culturally controversial.     

Kierkegaard and the internet: Existential reflections on education and community

If the rhetorical and economic investment of educators, policy makersand the popular press in the United States is any indication, thenunbridled enthusiasm for the introduction of computer mediatedcommunication (CMC) into the educational process is wide-spread.In large part this enthusiasm is rooted in the hope that throughthe use of Internet-based CMC we may create an expanded communityof learners and educators not principally bounded by physicalgeography. The purpose of this paper is to reflect critically uponwhether students and teachers are truly linked together as a``community' through the use of Internet-based CMC. The paper usesthe writings of Kierkegaard, and Hubert Dreyfus's exploration ofKierkegaardian ideas, to look more closely at the prospects andproblems embedded in the use of Internet-based CMC to create ``distributed communities' of teachers and learners. It is arguedthat from Kierkegaard's perspective, technologically mediatedcommunications run a serious risk of attenuating interpersonalconnectivity. Insofar as interpersonal connectivity is an integralcomponent of education, such attenuation bodes ill for some, andperhaps many instances of Internet-based CMC.     

No time to think: Reflections on information technology and contemplative scholarship

This paper argues that the accelerating pace of life is reducing the time for thoughtful reflection, and in particular for contemplative scholarship, within the academy. It notes that the loss of time to think is occurring at exactly the moment when scholars, educators, and students have gained access to digital tools of great value to scholarship. It goes on to explore how and why both of these facts might be true, what it says about the nature of scholarship, and what might be done to address this state of affairs.

Anonymity versus commitment: The dangers of education on the internet

I shall translate Kierkegaard's account of the dangers and opportunities of what he called the Press into a critique of the Internet so as to raise the question: what contribution -- for good or ill -- can the World Wide Web, with its ability to deliver vast amounts of information to users all over the world, make to educators trying to pass on knowledge and to develop skills and wisdom in their students? I will then use Kierkegaard's three-stage answer to the problem of lack of involvement posed by the Press -- his claim that to have a meaningful life the learner must pass through the aesthetic, the ethical and the religious spheres of existence -- to suggest that only the first two stages -- the aesthetic and the ethical -- can be implemented with Information Technology, while the final stage, which alone makes meaningful learning possible, is undermined rather than supported by the tendencies of the desituated and anonymous Net.     

互联网环境下服务质量决定因素的实证研究

为促进我国互联网商务的发展,本文根据传统环境下的SERVQUAL模型、技术采用模型和自服务技术理论,识别出了e 服务质量的决定因素,并提出研究模型及相应的假设。选择中国B—C网上经营环境为背景,以网络调研的方式收集了138份客户的样本数据,利用SPSS11 0软件对该研究模型进行了检验。检验结果表明:信任、易用性、反应性和可靠性是e 服务质量的决定因素。其中,信任的影响作用最大,其次是易用性、反应性,可靠性的影响较小。     

基于HEVC的ISC算法的颜色量化预处理

文章在基于HEVC框架下提出了增加颜色量化预处理的无损一维串匹配方法（Intra String Copy）。在没有颜色量化预处理环节的无损一维匹配算法可能会由于存在视频采集误差或是上下文造成的细微误差而导致匹配失败,这对以无损匹配为核心的ISC造成了很大的影响。文章借鉴了图像处理中八叉树的颜色量化方法,对视频图像信息进行颜色量化预处理后再进行一维串匹配编码,对屏幕图像视频的编码适应性有了很大的提升。

An empirical study of the rise of big data in business scholarship

Big data has captured the interests of scholars across many disciplines over the last half a decade. Business scholars have increasingly turned their attention to the impact of this emerging phenomenon. Despite the rise in attention, our understanding of what big data is and what it means for organizations and institutional actors remains uncertain. In this study, we conduct a systematic review on “big data” across business scholarship over the past six years (2009–2014). We analyzed 219 peer-reviewed academic papers from 152 journals from the most comprehensive business literature database. We conducted the systematic review both quantitatively and qualitatively using the data analysis software NVivo10. Our results reveal several key insights about the scholarly investigation of big data, including its top benefits and challenges. Overall, we found that big data remains a fragmented, early-stage domain of research in terms of theoretical grounding, methodological diversity and empirically oriented work. These challenges serve to improve our understanding of the state of big data in contemporary research, and to further prompt scholars and decision-makers to advance future research in the most productive manner.     

The Crisis of communication: Videotext,the internet and innovation in France and the United States

This article compares videotext in France and the United States, the two advanced industrialized countries where videotext was the most and least successful, respectively, in order to demonstrate how videotext as a techno-political project foreshadows the explosive growth of the Internet as the dominant global communications platform. It draws upon the theory of network effects, in combination with a comparative analysis of both the institutional settings for research and development and political discourse, to explain how the interaction between state, market, and culture shaped network development and policy outcomes. Data are drawn primarily from official policy documents and trade journals from the era.
