The WomenAction 2000 case data illustrate that the Internet situation among women's organizations in Africa is highly problematic. The women have specific computer network needs - and even among this 'group' the needs vary. They further represent grassroots women who have no access to computer networks. The survey data illustrate that appropriate theorizing on Internet working by women in Africa must address both technological and social issues. It must also integrate gender, North-South, context and other aspects. For this purpose, available approaches are neither complete nor entirely adequate. Together however, they offer enough building blocks to study African women and Internet introduction appropriately. Constructivist technology studies (including gender and technology approaches) offer good starting points for an appropriate model. Nevertheless, constructivism needs additions to support gender empowerment in the South. Critical development studies and the integrative view on global communications offer useful additions to this end.  相似文献

As a novel technology in the age of information, the Internet has become a fancy vehicle through which campaign messages can be delivered to prospective voters via multiple paths such as websites and emails. However, despite the effort put into making campaign messages as appealing as possible, studies show that the click-through rate of campaign emails remains relatively low. In the past, many studies concerning technology adaptation have focused on the aspect of “innovation diffusion” rather than “innovation resistance”. The aim of this study is to integrate ideas derived from the Technology Acceptance Model, the concepts of innovation resistance and the theory of ad avoidance to find the factors that influence voters' resistance of reading political emails. An online survey was conducted, in which a sample of 1012 voters in the 2009 local election in Taiwan was studied. The results showed that negative impression and perceived interruption were the factors behind people's resistance of politically-related emails. In addition, both of the above factors affected people's attitudes toward opening future political emails.  相似文献

Intention theories, such as the Theory of Reasoned Action, the Theory of Planned Behavior, and the Technology Acceptance Model (TAM), have been widely adopted to explain information system usage. These theories, however, do not explicitly consider the availability of alternative systems that users may have access to and may have a preference for. Recent calls for advancing knowledge in technology acceptance have included the examination of selection among competing channels and extending the investigation beyond adoption of a single technology. In this study, we provide a theoretical extension to the TAM by integrating preferential decision knowledge to its constructs. The concept of Attitude‐Based Preference and Attribute‐Based Preference are introduced to produce a new intention model, namely the Model of Technology Preference (MTP). MTP was validated in the context of alternative behaviors in adopting two service channels: one a technology‐based online store and the other a traditional brick‐and‐mortar store. A sample of 320 responses was used to run a structural equation model. Empirical results show that MTP is a powerful predictor of alternative behaviors. Furthermore, in the context of service channel selection, incorporating preferential decision knowledge into intention models can be used to develop successful business strategies.  相似文献

This paper investigates an empirical puzzle in technology adoption for developing countries: the low adoption rates of technologies like hybrid maize that increase average farm profits dramatically. I offer a simple explanation for this: benefits and costs of technologies are heterogeneous, so that farmers with low net returns do not adopt the technology. I examine this hypothesis by estimating a correlated random coefficient model of yields and the corresponding distribution of returns to hybrid maize. This distribution indicates that the group of farmers with the highest estimated gross returns does not use hybrid, but their returns are correlated with high costs of acquiring the technology (due to poor infrastructure). Another group of farmers has lower returns and adopts, while the marginal farmers have zero returns and switch in and out of use over the sample period. Overall, adoption decisions appear to be rational and well explained by (observed and unobserved) variation in heterogeneous net benefits to the technology.  相似文献

基于TAM的大学生微博使用影响因素实证研究   总被引:1,自引:0,他引:1  
本文基于技术接受模型(TAM)就大学生微博使用影响因素进行研究分析,建立了大学生微博使用影响因素模型,并以问卷调查的方式给予实践证明,得出如下结论:大学生使用微博的态度主要由用户对微博的感知有用性及感知易用性决定;感知易用性由微博的发布内容要求是否简单、操作是否方便、是否支持多种方式登录等因素影响;感知有用性由感知易用性、记录与表达动机、信息获取动机、接近名人动机等因素影响,各因素影响程度由大到小排序是信息获取动机、接近名人动机、记录与表达动机、感知易用性。  相似文献

In this paper, we explore the capacity during the process of a firm's information system adoption and implementation from knowledge management perspective, based on a firm's level construct. According to the di- mensions of absorptive capacity proposed by Zahra and George, we point out that the concept of IS absorptive ca- pacity, analyze and summarize the elements of potential absorptive capacity and realized absorptive capacity. We use data from two manufacturing organizations, analyze two firm's realities of IS absorptive capacity. The study indicates differing antecedents may have differing effects on potential absorptive capacity and realized ab- sorptive capacity.  相似文献

The article discusses several hemispheres of human resource management based on a typical case review. The study presents the main problems of the case from both employees and organizations; the issued problems involve compensa- tions and benefits, restructuring, job design, and training. Based on the analysis of the ease, two alternative solutions state that the potential routes for the organizations to avoid serious negative results. The study intreduces a number of recommen- dations that can be used as a reference for other organizations to avoid similar risks.  相似文献
