2. 1. Quasi-subscribers in the Swedish Mobile Phone Market: The Phenomenon and Determinant Factors

   Author : Tsani Annafari; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; quasi-subscribers; diffusion process; multiple subscriptions; inter-operator multiple subscriptions; intra-operator multiple subscriptions; Mobile phone;

   Abstract : This thesis investigates the problematic inaccuracies of mobile phone density as a measure on access and use of mobile phones. The inaccuracies are presumably caused by the presence of quasi-subscribers - mobile phone users with multiple active SIM cards or subscriptions - that exaggerate the actual number of mobile phone users.

4. 2. Understanding mobile service diffusion as an evolutionary process: A study of the Swedish market

   Author : Tsani Annafari; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; social evolution; mobile service; Innovation diffusion; variation; data granularity; diffusion modeling; selective retention;

   Abstract : This thesis aims to highlight the connections between the diffusion of innovation theory and the evolutionary models for technological changes within the context of mobile communication research. On the basis of empirical findings, the discussion focuses on addressing three research questions: Why should mobile service diffusion be understood as an evolutionary process? How should mobile service diffusion be explained and modelled using evolutionary conceptions? And in what way the evolutionary framework could influence future mobile service diffusion studies?Based on empirical observations and a literature study, this thesis argues that mobile service diffusion involves dynamic, developmental and historical economic process which is comparable to an evolutionary process.

5. 3. Enabling Internet-Scale Publish/Subscribe In Overlay Networks

   Author : Fatemeh Rahimian; Seif Haridi; Šarunas Girdzijauskas; Márk Jelasity; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Publish Subscribe; Content Distribution; Peer-To-Peer Overlay Network; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Abstract : As the amount of data in todays Internet is growing larger, users are exposedto too much information, which becomes increasingly more difficult tocomprehend. Publish/subscribe systems leverage this problem by providingloosely-coupled communications between producers and consumers of data ina network. Data consumers, i.e. READ MORE

6. 4. Gossip-based Algorithms for Information Dissemination and Graph Clustering

   Author : Fatemeh Rahimian; Seif Haridi; Eiko Yoneki; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Decentralized algorithms are becoming ever more prevalent in almost all real-world applications that are either data intensive, computation intensive or both. This thesis presents a few decentralized solutions for large-scale (i) data dissemination, (ii) graph partitioning, and (iii) data disambiguation. READ MORE

7. 5. Ownership or Access? : A study of mobility services in the access economy

   Author : Brenda Nansubuga; Christian Kowalkowski; Erik Sundin; Tobias Schäfers; Linköpings universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Abstract : The access economy is a business model emphasizing temporary access and usage over permanent ownership, centered on the renting of products among individuals or organizations. Endorsed by the media, analysts, and researchers, access-based services, which allow customers to pay for the temporary use of a product without owning it, have gained popularity in various consumer and business-to-business industries, including mobility, fashion, and mechanical equipment.
