This paper proposed a framework based on the theory of Task-Technology Fit (TTF) to understand MTs and their implications for m-government applications. Following the framework, we reviewed current MTs, categorised e-government tasks and reviewed and summarised existing m-government applications. To measure the degree of fit between MTs and government tasks performed through them, and its importance in the successful m-government implementation, we then discussed the benefits and challenges of m-government.

However, not many have successfully implemented it. Availability of inexpensive tools does not guarantee their usage by organizations and their employees. To have Enterprise 2.0 implemented widely and effectively by organizations, it is important that both managers and employees benefit from using it. It is expected that the level of congruence of management–employees perceived benefits would affect the level of adoption of Enterprise 2.0 in organizations. Testing this is the purpose of this research. Using the case study of two large global organizations, this study analyzed the use of Enterprise 2.0 by both employees and managers. The results showed that even though both employees and managers believe that Enterprise 2.0 usage does have a positive impact on communication, collaboration, community building, and employee engagement, the level of belief is different: managers' perception of Enterprise 2.0 benefits is less than that of employees. There was a greater degree of congruence though between both the groups on the perceived benefits of Enterprise 2.0 on knowledge management and organizational outcomes. The size and the type (not-for-profit) of organization was a disadvantage in adopting such tools. The not-for-profit organization was more at loss when applying Enterprise 2.0 as its employees are less aware of the type of tools and of their benefits, and there is less managerial support.

One of these new services is the mobile augmented reality system (MARS). MARS integrates virtual information into the physical environment where a smart phone is located, allowing smart phone users to receive virtual information as if it is part of their physical surroundings. Several studies have suggested techniques/methods to match the best relevant information with the physical surrounding/object. Most of them identify the objects on the photo based on image comparison of the photo taken by a smart phone with images stored in a database. This method however is slow, as it takes time to do the image comparison. In this study we propose a new method, which can identify objects in a smart phone photo much faster and with a higher degree of accuracy, by using the phone's sensor data and electronic maps.

''Metaverse services'' is a collective term for services such as Augmented reality, Life logging, Mirror world, and Virtual world. Among them, Twitter, Google, iPhone, and Secondlife (T.G.I.S) are the most popular services/ products these days. To measure the adoption of these product/services, the most commonly used are IP traffic and iPhone sales. Thus, in this study, we measured adoption by measuring changes in the IP traffic volume of Twitter.com, Maps.Google.com, Secondlife.com, and sales for iPhone during a 2-year period (from the first quarter of 2008 to the fourth quarter of 2009). To analyze this time series data to reveal the innovation and imitation effect, we employed the Bass model. The results showed that each of these services yields different innovation and imitation coefficient values. Imitation effects for all Metaverse services are greater than innovation effects, and Secondlife's innovation effects are larger than others. Also, iPhone sales, as a measurement for information and communication technology (ICT) products, showed greater innovation effects than the other services. Implications are drawn to explain these differences, such as, Google-map's imitation effects are based on network externalities, while Twitter's imitation effects are caused by the interactions of individuals; iPhone sales' innovation effects are explained by the timing of the measurement.

For this purpose, this paper conducted multivariate analysis of covariance by using ITIF as an independent variable and four dependent variables for CA: production cost, fast and reliable delivery, product quality, and flexibility of product design, which are also essential factors in IT buying decision making for organizations. The results of this study show that having a flexible IT infrastructure positively influences all four variables of CA. Moreover, the result of the univariate analysis indicates that the SMEs' highest benefit of having ITIF is the improvement of product quality and an increased flexibility of product design. These results emphasize the importance of ITIF for SMEs and cloud computing, as a means for achieving this flexibility.

Design/methodology/approach – The Bass diffusion model is used to discern distinctive changes in users' adoption behavior due to the innovation and the imitation effects. Findings – The innovation effect is more influential for innovators and opinion leaders than it is for all adopters. However, it diminishes as time passes. Conversely, the imitation effect becomes a more powerful factor for the early majority, late majority and laggards. The imitation effect in the ICT industry is greater than that in the non-ICT industry, revealing the high network effect in ICT diffusion. Research limitations/implications – Mobile phones are not the representative of all ICTs as the automobiles also do not represent all utility products. More ICT and conventional products need to be included and compared for greater generalization of the results from different countries. Practical implications – By identifying the strong innovation effect of a new product at the early stage of its adoption, and the social network effect in the acceleration of the adoption speed through massive numbers of imitating consumers, this research reveals the ever shrinking product life cycle and therefore the importance of continuous disruptive innovation as a competitive strategy for organizations. Originality/value – The paper provides new theoretical insights into the technology adoption research by using a mathematical modeling methodology using real data. The study provides new insights into the strategic implications of innovation and imitation effects for technology service providers.

developments in business model design within the field of entrepreneurship. It is widely known that during the start-up process, entrepreneurs need to set up the boundaries of the business and define the product/service to offer. This is a very complex task, especially for new technology-based companies which usually require large investments and have a limited time span (avoiding product obsolescence) to turn the idea into a full-time venture. Although business model design within the entrepreneurship field is a recent topic, it is gaining a growing attention in the literature. The usefulness and predictable power of business models are expected to help entrepreneurs make more informed decisions, thus increasing the chances of success. This article first tackles the specific problems faced by new technology based firms, linking their needs with the advantages of having a flexible and well designed business model. Second, different innovative practices aimed at improving business model design are discussed. The paper ends with some recommendations, stressing the need for future empirical work.

This study examines the success of e-learning CMSs based on user satisfaction and benefits. Using DeLone and McLean's information system success model as a theoretical framework, we analyze the success of e-learning CMSs in five dimensions: system quality, information quality, instructional quality, user satisfaction, and CMS benefits. An analysis of survey data collected from students participating in a university-wide CMS shows that system quality, information quality, and instructional quality positively influence user satisfaction, which, in turn, increases the benefits of CMSs. By providing a comprehensive framework for the critical success factors in e-learning CMSs and their causal relationships, this study provides practical implications for managing e-learning courses and resources for a more flexible and effective CMS-centered, e-learning environment.

Accordingly, there is a growing interest in web accessibility (WA), which involves the creation of an environment in which everyone can equally access and use the web. WA is especially important to those who have disability as it can directly influence their quality of life. This study explores the factors that hinder WA for persons with disabilities and how can they be alleviated. Using a Delphi method, study showed that the main factors hindering web accessibility are lack of the following: publicity and awareness; management's interest; institutional or financial support from the government; objective evaluations of accessibility compliance; availability of experts; accessibility education and relevant educational institutions; the understanding of accessibility compliance. Being one of few pioneering WA studies, this research contributes to both theory and practice.

Even though blogs have been around for more than a decade and have been regarded as something which will shake up just about every business, their benefits and therefore usage by organisations are yet to be fully explored. Blogs’ usage by organisations depends not only on their benefits for the organisations themselves but also on employees’ willingness and perceived benefit of blog usage. Congruence between the two, the organisation’s and users’ benefits of blogs, is important for the acceptance of blog technology and worthy for study. By analysing these benefits and the concept of congruence, this study proposes a research framework that can be used by future empirical studies.
