Asymmetric Peer Influence in Smartphone Adoption in a Large Mobile Network
ASYMMETRIC PEER INFLUENCE IN SMARTPHONE ADOPTION IN A LARGE MOBILE NETWORK Qiwei Han, Department of Engineering and Public Policy, Carnegie Mellon University, 5000 Forbes Avenue, Pittsburgh, PA 15213, USA and Instituto Superior Técnico, University of Lisbon, Av. Rovisco Pais, Lisbon 1049-001, Portugal, [email protected] Pedro Ferreira, Heinz College and Department of Engineering and Public Policy, Carnegie Mellon University, 5000 Forbes Avenue, Pittsburgh, PA 15213, USA, [email protected] João Paulo Costeira, Instituto Superior Técnico, University of Lisbon, Av. Rovisco Pais, Lisbon 1049-001, Portugal, [email protected] Abstract Understanding adoption patterns of smartphones is of vital importance to telecommunication managers in today’s highly dynamic mobile markets. In this paper, we leverage the network structure and specific position of each individual in the social network to account for and measure the potential heterogeneous role of peer influence in the adoption of the iPhone 3G. We introduce the idea of core- periphery as a meso-level organizational principle to study the social network, which complements the use of centrality measures derived from either global network properties (macro-level) or from each individual's local social neighbourhood (micro-level). Using millions of call detailed records from a mobile network operator in one country for a period of eleven months, we identify overlapping social communities as well as core and periphery individuals in the network. Our empirical analysis shows that core users exert more influence on periphery users than vice versa. Our findings provide important insights to help identify influential members in the social network, which is potentially useful to design optimal targeting strategies to improve current network-based marketing practices. -

Mobile Leapfrogging and Digital Divide Policy Assessing the Limitations of Mobile Internet Access
New America Foundation Mobile Leapfrogging and Digital Divide Policy Assessing the limitations of mobile Internet access By Philip M. Napoli and Jonathan A. Obar1 April 2013 This paper examines the emerging global phenomenon of mobile leapfrogging in Internet access. Leapfrogging refers to the process in which new Internet users are obtaining access by mobile devices and are skipping the traditional means of access: personal computers. This leapfrogging of PC-based Internet access has been hailed in many quarters as an important means of rapidly and inexpensively reducing the gap in Internet access between developed and developing nations, thereby reducing the need for policy interventions to address this persistent digital divide. This paper offers a critical perspective on the process of mobile leapfrogging. Drawing upon data on Internet access and device penetration from 34 countries, this paper first shows that while greater access to mobile technologies suggests the possibility of a leapfrog effect, the lack of 3G adoption suggests that mobile phones are not yet acting as functionally equivalent substitutes for personal computers. Next, this paper puts forth a set of concerns regarding the limitations and potential shortcomings of mobile-based Internet access relative to traditional PC-based Internet access. This paper illustrates a number of important relative shortcomings in terms of memory and speed, content availability, network architecture, and patterns of information seeking and content creation amongst users. This paper concludes that policymakers should be cautions about promoting mobile access as a solution to the digital divide, and undertake policy reforms that ensure that communities that rely on mobile as their only gateway to the Internet do not get left further behind. -
Analyzing Key Factors Affecting the Adoption Intentions of 3G Mobile Services in Turkey
Master Programme in Economic Growth, Innovation and Spatial Dynamics Analyzing Key Factors Affecting the Adoption Intentions of 3G Mobile Services in Turkey Ezgi Baran [email protected] Abstract: Third generation mobile communication standard (3G) is an incremental innovation which follows the prior developments from 1G to 2,5G and provides several services including intranet/extranet access, customized infotainment, multimedia messaging service, internet access, location-based services and rich voice. This study aims to analyze key factors influencing possible 3G acceptance in Turkey, where 3G is expected to be released by July, 2009. This study provides explanations to (1) the significance of the influence of critical factors, adapted from established theories of innovation, on the acceptance of 3G (2) demographic characteristics of the individuals influencing adoption intentions of 3G technologies. In doing so, this study draws upon several well- known theories, namely, technology acceptance model (TAM), the theory of planned behavior (TPB), diffusion of innovation theory and network externalities theory. The study is conducted via an online survey, through which 282 responses are obtained. It uses descriptive statistics and Multinomial Logistic Regression to analyze data and examine the influence of the defined critical factors and demographic characteristics on 3G adoption intentions. Keywords: Innovation, adoption, diffusion of innovations, network externalities, 3G EKHR 21 Master’s Thesis (15 credits ECTS) June 2009 Supervisor: Olof Ejermo Examiner: Ola Jonsson ACKNOWLEDGEMENTS First of all, I would like to sincerely thank my supervisor, Olof Ejermo, for his constant guidance. Without his able supervision, the pieces would not come together. I owe a lot to my bestest friend Merve Şeker, for her friendship and support during my sleepless nights studying on this research paper. -

In-cell touch by Vcom blocks has been a dominant touch technology for thin-film-transistor liquid- crystal display (TFT-LCD) displays in mobile phone application. However, the growth has slowed down after its high penetration rate. Panel makers will extend the technology to larger-sized tablet and notebook PC applications. Panel makers will prioritize the in-cell touch development for tablet PC application because of its bigger market size. The in-cell touch technology for notebook PC application will grow remarkably from 2021 onwards. Although in-cell touch by Vcom blocks already accounts for more than 93% shipment shares of the total in- cell TFT-LCD shipments in mobile phone application, it seems that its remarkable growth in recent years will end soon (78% YoY in 2018 and 56% YoY in 2019). The reason is that AMOLED display demands, including on-cell and GF2 touch sensors, are surging and they are replacing in-cell TFT-LCD, especially in the midrange and high-end segments. Furthermore, two in-cell touch technologies—Apple’s Vcom pattern type and Japan Display’s (JDI) hybrid type—are declining because major smartphone brands are shifting to on-cell AMOLED. -

Motorola Micro Tac Classic
Motorola Micro Tac Classic Product: Motorola Micro Tac Classic Date of Design: 1992 Designer / Retailer: Motorola Cost 1992: - Cost 2007: £40 Retro Brick state… The Motorola MicroTAC phone set a new design standard for 1989 with a flip-lid mouthpiece. As the smallest and lightest phone on the market, the unit weighed 12.3 ounces, measured 6.75 x 2.25 x 1.25 inches and retailed between £1,200 and £1,800… ouch. This phone is actually third generation of this particular design and was launched in 1991/2 ‘This was a whole new direction for Motorola. New technological advances meant that the equipment could be radically downsized. And so began the quest to be the smallest, lightest and most portable. The original MicroTAC was a completely new design and was the first phone to use this radical flip. There are also few things about it which are quite unusual.... The small hole in the front of the flip gave you the impression that there was a microphone in the flip which was positioned directly in front of your mouth, however, the microphone is actually situated just behind a tiny hole in the main part of the phone just between the right hand hinge and the call end button on the bottom right. Another puzzling design feature was the retractable aerial. In fact, the aerial does absolutely nothing as it is purely for show. The unit features an internal antenna, however, the pull up plastic was added after focus groups in the US felt that any phone should have a visible aerial. -
