Information and communication technologies in use in government systems can bring about expected benefits only when citizens are willing and able to use such systems. Previous studies from various disciplines provided a fundamental understanding of human behavior with technology adoption that focused mainly on the technical and supply sides of this adoption. We argue that it is necessary to move away from an assumption that users form a homogeneous group under the phenomenon of the digital divide. Having conducted an online experiment, this study empirically examined the effects of personal factors, particularly the perceived information literacy, and the perceived information overload, on the user’s perceptions on the usefulness and trust in a government website. We find that the higher an individual perceives one’s information literacy, the more he or she trusts the website, and this is mediated by one’s perceived information overload (negatively) and perceived usefulness (positively). This research provides a more balanced understanding of the behavior of e-government adoption, supplemented with the details of citizen engagement factors, and specifies meaningful practical implications for successful e-government policies. 相似文献

Participation in and adding content to social tagging tools is important for these tools to achieve their purpose of classifying and organizing information. Users of social tagging tools are driven to participate and add tags by extrinsic and intrinsic motivation. Extrinsic motivation is dominating research as a main predictor of why users use information systems. Social tagging tools, as a subset of social media tools, are distinguished by their unique social aspect that makes intrinsic motivation a potential driver for users to add tags to content. Intrinsic motivation, when applied to social tagging tools, could entail many shades that represent different users’ motives for using such tools. In this paper, we add a rich concept of intrinsic motivation to include hedonism as a main predictor of users’ behavior on social tagging tools. We empirically validate a previously proposed theoretical model of three dimensional concepts of hedonism with three components describing individuals’ hedonic state when interacting with social tagging tools: explorability, curiosity, and enjoyment. After a robust and thorough data analysis using structured equation modeling, the results confirm our theoretical model and suggest using a richer concept of enjoyment to reflect a hedonic dimension when investigating intrinsic motivation with interactive social media tools. Our validated model could be the spark of new factors that have the potential to influence user acceptance of information systems in general and in social media tools. This research contributes to the development of attitude-behavior theories that could explain users’ acceptance of dynamic web 相似文献

As suggested by prior studies, tacit knowledge sharing is a natural process of social interaction. The perspectives of social capital and behavioural control are thus employed in this study to investigate an employee's tacit knowledge sharing and behaviour within a workgroup. This study collects data through a multi-informant questionnaire design. Three interesting results were obtained in this study. First, results show that tacit knowledge sharing intention can be induced by affect-based trust. However, shared value is negatively related to tacit knowledge sharing intention. Second, internal control has a positive effect on tacit knowledge sharing intention, but the relationship between internal control and tacit knowledge sharing behaviour could not be confirmed. Third, external control positively moderates the relationship between tacit knowledge sharing intention and behaviour. It is interesting to note that tacit knowledge sharing intention does not necessarily lead to tacit knowledge sharing behaviour unless the moderating effect of external control is taken into account. These findings and their implications are also addressed. 相似文献

The concept of acculturation has been based on the assumption of an adaptation process, whereby immigrants lose aspects of their heritage cultures in favour of aspects of a host culture (i.e. assimilation). Past research has shown that acculturation preferences result in various possibilities and influence consumption behaviour. However, the impact of social media on consumer acculturation is underexplored, although the social purpose and information sharing online is utilized for a variety of social purposes. Recent studies have shown the transformation from an offline to an online context, in which social networks play an integral part in immigrants’ communications, relationships and connections. This study merges the views from a number of leading contributors to highlight significant opportunities and challenges for future consumer acculturation research influenced by social media. The research provides insights into the impact of social media on consumer acculturation. 相似文献

The blockchain is considered to be the potential driver of the digital economy. The Blockchain technology outweighs the challenges associated with the traditional transaction business governed and regulated by the third trusted party. There is a growth in the interest among the researchers, the industry, and the academia to study and leverage the potential of Blockchain. Blockchain provides a decentralized and distributed public ledger for all the participating parties. Though it seems that blockchain is a viable choice and solution for all the centralized governed and regulated transactions (in digital online space), it has potential challenges that need to be resolved; opportunities to be explored, and applications to be studied. This paper utilizes a systematic literature review to study several research endeavors made in the domain of blockchain. To further research on blockchain adoption, the paper theoretically constructs an integrated framework of the blockchain innovation adoption process in an organization considering organizational and user acceptance perspectives. This would facilitate its widespread adoption, thereby achieving sustained leadership solutions. The paper offers 23 propositions to information systems (IS)/information management (IM) scholars with respect to innovation characteristics, organizational characteristics, environmental characteristics, and user acceptance characteristics. Further, the paper explores several areas of future research and directions that can provide deep insights for overcoming challenges and for the adoption of blockchain technology. 相似文献

The advent of the participatory Web and social network applications has changed our communication behaviour and the way we express ourselves on the Web. Social network application providers benefit from the increasing amount of personally identifiable information willingly displayed on their sites but, at the same time, risks of data misuse threaten the information privacy of individual users as well as the providers’ business model. From recent research, this paper reports the major requirements for developing privacy-preserving social network applications and proposes a privacy threat model that can be used to enhance the information privacy in data or social network portability initiatives by determining the issues at stake related to the processing of personally identifiable information. 相似文献

The purpose of this study was to examine the use of information by environmental planners. The study used the Grounded Theory method to develop a theoretical model that explains the reasons for using information and the factors that motivate such use. Forty-four semi-structured interviews were conducted in workplace environments to collect data on the way the respondents used information in projects that they had done before. Data were analysed in accordance with the Grounded Theory techniques of constant comparison. The study found that the planner’s perceptions of: their own competences, resistance of the stakeholders, role requirement; and the impressions on the enabling effect of the information environment drive the self-empowerment behaviour of the planners. This behaviour is characterised by actions involving information acquisition, packaging as well as giving information to stakeholders during the facilitation of the environmental planning process. The experiential knowledge levels of individuals enhance the self-empowerment behaviour exhibited by environmental planners. Based on the informational power derived from the self-empowerment activities, the planners select a strategy for participation that they deem appropriate for an environmental planning project, consequently facilitating the process to develop widely accepted environmental plans. 相似文献

The rise of social media has led to changes in how entrepreneurs carry out their day-to-day activities. Studies on social media and entrepreneurship are relatively new and fragmented in their focus, however there is increasing interest from academia and practitioners for further research and investigation within this area. This study systematically reviews research carried out in the domain of social media and entrepreneurship. A total of 160 papers, published between 2002 and 2018 were synthesised to identify critical theories and research methods used in the domain. Based on the extent review, an integrative framework was developed to identify relationships amongst elucidated constructs. While most papers investigated the factors that drive social media adoption and use by entrepreneurs, it was found that the use of social media by entrepreneurs had transcended marketing and it is now used in business networking, information search and crowdfunding for their business. This has led to significant impact with improved firm performance and innovation enhancement being the essential outcomes. The literature review and framework further understanding of social media and entrepreneurship research, providing a useful basis for future studies and informs practice in this area. 相似文献

Research on the adoption of systems for big data analytics has drawn enormous attention in Information Systems research. This study extends big data analytics adoption research by examining the effects of system characteristics on the attitude of managers towards the usage of big data analytics systems. A research model has been proposed in this study based on an extensive review of literature pertaining to the Technology Acceptance Model, with further validation by a survey of 150 big data analytics users. Results of this survey confirm that characteristics of the big data analytics system have significant direct and indirect effects on belief in the benefits of big data analytics systems and perceived usefulness, attitude and adoption. Moreover, there are mediation effects that exist among the system characteristics, benefits of big data analytics systems, perceived usefulness and the attitude towards using big data analytics system. This study expands the existing body of knowledge on the adoption of big data analytics systems, and benefits big data analytics providers and vendors while helping in the formulation of their business models. 相似文献

This article reports the results from an information and knowledge assessment (IKA) to identify information and knowledge needs and, their coverage by information resources to derive recommendations for improvement and proposes a contingeny framework. The approach is based on a review of audit methods from information sciences and management, knowledge management and the engineering discipline and tested with data (N = 580) collected from the engineering domain within an automotive supplier over six European sites. The integrated assessment uses content needs profiles from two complementary perspectives, the coverage of needs by various internal information sources and data on awareness and usage of these information sources. The employment of content categories on a more granular analytical level than information systems sources opens up new possibilities to derive improvement measures and requirements for the design of information systems within an organization. The brief data-gathering instrument also reduces the required resources to implement this approach considerably overcoming weaknesses previously identified in case studies and the IA literature. It makes a contribution to research bridging the gap between research and practice and opens up options to design contingency frameworks for a specific domain. 相似文献

Abstract This is an appraisal of the impact that the mechanization of knowledge has had upon modern society, and a search for the driving force behind this mechanization. The investigation starts by examining the multimodal structure of social systems, giving special consideration to the discrete modal orders that are found in a civilized and humane society. It proposes a multimodal definition of information that determines the information requirements of such a society. A distinction is then suggested between information systems and information machines, followed by an inquiry into the historical roots that have urged society to rely increasingly upon information machines for knowledge while dismissing information systems. The discussion concludes with some social illustrations that show the effect of mechanistic information upon modern lives. 相似文献

Organisations increasingly realise that they must transform into true digital enterprises to create competitive advantage and ensure corporate survival. However, many organisations do not realise that successful digital transformation (DT) requires much more than technology; it can only succeed if they manage their data, information and knowledge as true business assets. This paper describes collaborative research conducted by academic and industry partners, a mutually beneficial journey spanning the past ten years. The aim was to develop a Holistic Information Asset Management (HIAM) model indicating the important areas of information asset management (IAM) that support the DT journey. Interviews were conducted with C-level executives in organisations from all industries on three continents to investigate their IAM practices, the barriers to good IAM and the benefits of managing information assets (IAs) well. This paper proposes that organisations should focus on ten domains in their quest for effective IAM: i) business benefits, ii) business environment, iii) executive awareness, iv) leadership and management, v) information environment, vi) information systems, vii) information behaviour, viii) information attributes/quality, ix) information performance and x) justification. 相似文献

基于复杂社会网络的创新扩散多智能体仿真研究 《科学学研究》2013,(2):310-320
创新扩散是由潜在采纳者的微观采纳决策所共同涌现出的宏观动力学行为。以复杂社会网络为创新扩散建模载体,通过建立潜在采纳者在社会学习和规范压力双重影响下的创新采纳决策及扩散机制,运用基于多智能体的仿真研究方法,研究微观层面因素是如何影响创新的宏观扩散。研究发现：无标度社会网络下的创新扩散深度最大及扩散速度最快;潜在采纳者的创新信息评价策略会显著地影响创新扩散深度;初始采纳者比例的提高可加快创新扩散速度,但无法持续提高扩散深度;过强或过弱的观念领导者创新性,均不利于创新扩散的深度;不同的初始采纳者类型对创新扩散深度、以及观念领导者创新性的强弱对创新扩散速度的影响取决于社会网络的拓扑结构。研究结果对于制定创新推广策略具有一定的指导意义。 相似文献

In this paper, we present the state of the art in the field of information retrieval that is relevant for understanding how to design information retrieval systems for children. We describe basic theories of human development to explain the specifics of young users, i.e., their cognitive skills, fine motor skills, knowledge, memory and emotional states in so far as they differ from those of adults. We derive the implications these differences have on the design of information retrieval systems for children. Furthermore, we summarize the main findings about children’s search behavior from multiple user studies. These findings are important to understand children’s information needs, their search strategies and usage of information retrieval systems. We also identify several weaknesses of previous user studies about children’s information-seeking behavior. Guided by the findings of these user studies, we describe challenges for the design of information retrieval systems for young users. We give an overview of algorithms and user interface concepts. We also describe existing information retrieval systems for children, in specific web search engines and digital libraries. We conclude with a discussion of open issues and directions for further research. The survey provided in this paper is important both for designers of information retrieval systems for young users as well as for researchers who start working in this field. 相似文献

Cloud computing is a pervasive computing paradigm that has revolutionized how computer infrastructure and services are delivered. Current research trends on cloud computing have been focused on the technology, applications, costs, benefits, and security of cloud computing at the organizational level within small and medium sized enterprises. Little research attention has been paid on adoption and usage of cloud computing at educational establishments and how contextual factors can influence diffusion and adoption of cloud computing. Universities in developing countries are faced with challenging socio-economic and political constraints that limit their ability to invest in expensive information systems to compete on the global stage. Using constructs from the diffusion of innovation theory and the technology acceptance model, this paper proposes a model that takes account of contextual, economic, and technological influences in the perception and adoption of cloud computing at universities in sub-Saharan Africa. Results from a pilot study, based on the model, through a survey of university lecturers and IS experts shows reliability and validity of the instrument and supports its usage for a more extensive study. Implications, potential contributions to research, and suggestions for future study are discussed. 相似文献
