Selected AbstractsNTT DoCoMo's Launch of I-Mode in the Japanese Mobile Phone Market: A Knowledge Creation Perspective*JOURNAL OF MANAGEMENT STUDIES, Issue 1 2007Vesa Peltokorpi abstract While innovation and knowledge creation processes and context are interlinked in the real world, scholars frequently ignore or separate context from knowing due to an entrenched sense of ontological and analytical dualism. This paper builds on the organizational knowledge creation theory (Nonaka, 1994) to provide a holistic view of contextual innovation and knowledge creation processes. The phenomenon is demonstrated by a longitudinal case description of i-mode mobile Internet innovation at NTT DoCoMo, a Japanese mobile communications company. This case explains how three key managers created and organized an interlinked system of shared contexts, called ba, that enabled the combination and open flow of diverse knowledge and led to the creation and launch of the i-mode mobile Internet, which unites novel technologies and services. Managerial implications and limitations are discussed. [source] Consumer confusion in the Thai mobile phone marketJOURNAL OF CONSUMER BEHAVIOUR, Issue 6 2006Sheena Leek Consumer confusion is likely to be an ever increasing problem as customers live in an environment where they are bombarded with information and where rapid technological developments are taking place. Although consumer confusion has been investigated in individualistic cultures such as the United Kingdom, it has received little attention in collectivist cultures such as Thailand. This research examines confusion in the Thai mobile phone industry. More specifically, it aims to determine what aspects of the mobile phone industry are confusing and what sources of information are used to reduce or eliminate it. Thai consumers experience confusion and find a number of aspects of the mobile phone industry to be problematic especially handsets, services and tariffs. In terms of reducing confusion, family and friends are the most popular source of information being both credible and reliable. It is put forward that the problems associated with handsets, services and tariffs are due to differing degrees of technological complexity and overchoice both of which are sub-components of confusion.

Reaney Temperature-stable, medium-permittivity dielectric ceramics have been used as resonators in filters for microwave (MW) communications for several decades. The growth of the mobile phone market in the 1990s led to extensive research and development in this area. The main driving forces were the greater utilization of available bandwidth, that necessitates extremely low dielectric loss (high-quality factor), an increase in permittivity so that smaller components could be fabricated, and, as ever in the commercial world, cost reduction. Over the last decade, a clear picture has emerged of the principal factors, that influence MW properties. This article reviews these basic principles and gives examples of where they have been used to control microwave properties and ultimately develop new materials. [source] Discriminatory Dealing with Downstream Competitors: Evidence from the Cellular IndustryTHE JOURNAL OF INDUSTRIAL ECONOMICS, Issue 3 2000David Reiffen One concern about regulated monopolies entering unregulated vertically-related markets is that they will discriminate against competitors of their unregulated affiliates. However, prohibiting regulated monopolies from offering related goods may preclude production by the most efficient provider. We take advantage of variation across geographic cellular phone markets in the US to examine the effect of integration on output, quality and prices. We find some evidence consistent with efficiencies (greater concentration of lines to users is associated with greater output and higher quality) and some consistent with discrimination (greater interconnection facility ownership concentration is associated with lower output and quality).
