This paper aims to provide an in-depth analysis of the process of standards setting based on the case of long-term evolution time division duplex (LTE TDD) deployment in China.

Using actor-network theory (ANT) as a theoretical framework, multi-level analyses are presented to explain the process of adoption of LTE TDD at a global level.

Findings identified the complex interaction between the social and technical aspects of fourth-generation (4G) by highlighting the co-evolving nature, diversity and interface that constitute the next-generation network environment.

ANT provides a framework of ideas for describing the process of technology adoption and for developing stories that explain it.

The findings shed light on a critical insight of the interrelationships between TD-SCDMA and LTE TDD and identify the policy successes and failures of 4G mobile networks.

The purpose of this study is to examine students' perception of mobile technology adoption for library service apps as a lens to explore the factors affecting mobile learning in higher education.

With the data collected from university students from Hong Kong and Japan, the authors conducted a comparative study for gaining a better understanding of students' perceptions toward adopting mobile apps as learning tools and other socio-cultural factors affecting such adoption. In particular, the authors derive alternative models from our analysis (benchmarked on technology acceptance model and unified theory of acceptance and use of technology) for a better explanation of the formation of the intentions, and, more importantly, cultural factors would affect such formation, as informed by the Hofstede Cultural Dimensions.

The findings are valuable for enhancing the effectiveness and adoption of mobile services for teaching and learning purposes in the context of higher education, as the focus of promotion of services should be tailored to the different student expectations in different regions, e.g. mainly performance expectancy in Japan versus in Hong Kong facilitating condition, performance expectancy and perceived usefulness altogether.

Defined as contributing to the development of learning assistance, mobile technology for library use and information access have become a significant issue raised in many higher educational institutions over the world, as the characteristics of mobile technology, such as portability and mobility, strengthen its possible use in education. However, scant research has been done in understanding the perception of mobile library use and factors affecting the behavioral intentions through the use of mobile technologies in Hong Kong and most Asian countries have not been sufficiently studied.

This paper investigates the main trends and uncertainties that will define fourth generation mobile systems and services (4G) in Europe. It outlines two divergent visions on 4G: the so‐called “immediate” 4G vision, consisting of wireless local area networks (WLANs) combined with other wireless access technologies, competing with 3G in the short term, and the so‐called “linear” 4G vision, in which the 3G standard is not replaced until the end of its life cycle by an ultra‐high speed broadband wireless network. Which of these visions will materialise, and what this means for the competitiveness of the main 4G stakeholders in Europe, will be to a large extent determined by which business models are feasible for 4G.

The purpose of this study is to analyse factors influencing subscribers' usage of 3G mobile services in Taiwan.

The research model, based on a technology acceptance model (TAM) and added perceived enjoyment, was tested by means of a two‐stage structure equation modelling approach. Data were collected from 532 respondents via a web questionnaire survey.

The findings indicate that perceived usefulness, perceived ease of use and perceived enjoyment are positively related to attitude, and perceived enjoyment has a positive influence on perceived usefulness.

The findings suggest users of 3G mobile services need to be provided with more diverse and entertaining ways of communicating, which are at the same time easily accessible and convenient to use.

A new correlation from perceived enjoyment to perceived usefulness was found to have a significant effect. This finding indicates enjoyment as a key factor influences customers' adoption of 3G services.

To survey ambient intelligence research in Europe, the USA and Japan and, in particular, in the context of the issues of privacy, identity, security and trust and the safeguards proposed to protect them.

This paper is based on research being conducted by the SWAMI consortium under the EC's Sixth Framework Programme. SWAMI stands for Safeguards in a World of Ambient Intelligence. The consortium comprises five partners: the Fraunhofer Institute (Germany), the Technical Research Center of Finland (VTT Electronics), Vrije Universiteit Brussel (Belgium), the Institute for Prospective Technological Studies (IPTS) (Spain) and Trilateral Research & Consulting (UK). The 18‐month SWAMI project began in February 2005.

Most AmI projects do not take into account privacy, security and related issues. However, a reasonable number do (perhaps a quarter of those in Europe) to a greater or lesser extent and some have proposed safeguards.

This paper references only a limited set of the research projects being carried out in Europe, the USA and Japan. More detailed information can be found on the SWAMI web site (http://swami.jrc.es).

A mix of different safeguards will be needed to adequately protect privacy, etc. in the new world of AmI.

Until now, there has been no reasonably comprehensive survey of AmI research projects in Europe, the USA and Canada focused on privacy, security, identity and trust issues. None has considered the range of safeguards needed to protect privacy, etc.

The aim of this paper is to discuss intellectual capital (IC) from a valuation perspective and examine the nature of such capital and why traditional valuation methods fail to reflect the unique characteristics of IC and propose an alternative approach that captures them.

The paper builds on the existing literature in the fields of financial valuation and IC. The analysis of these fields allows us to combine them and discuss the possible usage and limitations of real option models for the assessment of intellectual capital in firms.

A valuation perspective is developed based on the real option models that have been extended from their origin in financial asset valuation to the valuation of firms' growth opportunities. Intellectual resources embody these opportunities contributing to both their evolution over time and their realisation in future. A typology of IC is developed based on the influence upon the various valuation parameters of real options. This approach provides a richer framework to analyse the relationship between IC and corporate value.

Clarification of the relationship between IC and managerial flexibility as a source of value will help managers understand how they can create and leverage such flexibility to create value. The paper enables managers to understand how different types of IC impact on risk taking, timing of investment projects and the value of speculative investments.

The paper clarifies the nature of IC in the way it contributes to managerial flexibility to gain competitive advantage and exploit growth opportunities. It extends the real options valuation framework to the valuation of intellectual assets thus providing a link among intellectual assets, business strategy and firm value.

In order to understand the influence of technology innovation on market demand diffusion in the ICT service market, the purpose of this paper is to examine technology innovation in the mobile product market, which keeps a complementary relationship with the mobile communication market.

This study collected mobile communication user information of four leading countries in the ICT market – the USA, the UK, Korea, and Japan from 1981 to 2014. This study applies the Bass diffusion model to analyze the form of market demand diffusion and conducts white noise test to verify the hypotheses.

Technology innovation of mobile communication leads to an increase in innovation effect and a decrease in imitation effect. Thus, technology innovation of mobile communication needs to be promoted continuously for the purpose of increasing adopters in the early stage. Besides, mobile product’s technology innovation leads to an increase in imitation effect and a decrease in innovation effect, because individuals were aware of the usefulness of the products and services. Hence, the increase in the number of imitators caused a higher increase in imitation effect than in the mobile communication’s innovation effect.

Based on the results of this study, the role that product and service technology innovation plays in renewing the form of market demand diffusion in the ICT service market was defined. Also, since the strategies and plans to acquire competitive advantage of business were understood, it may help both companies and policy decision makers.

This paper addresses the potential need for European public policy actions in the area of mobile communications, in particular of developments towards 4th generation networks (4G). The paper is based on work conducted for the EC/JRC/IPTS/ESTO project “The Future of Mobile Technologies in EU: Assessing 4G Developments”. The paper first reviews developments of 3G and 4G technologies in Japan, Korea, China and the USA. It briefly addresses potential costs and benefits of competition in infrastructures. The paper states that initiatives in Europe for technologies beyond 3G tend to address research issues, while players in Asia and the USA are aiming at sales of 4G‐equipment supposed to start as soon as possible. In conclusion, nine options for policy makers are presented, such as to stimulate 2.5G and 3G data markets, to analyse actual spectrum use, to continue analysing approaches competing with UMTS, to estimate costs and benefits of new approaches to spectrum regulation, and to evaluate steps towards frequency allocation.
