Management von Kundenbeziehungen durch Brand Communities

2010

Das Marketing wurde in den letzten Jahrzehnten durch die Betrachtung von dyadischen Beziehungen zwischen Anbietern und Nachfragern dominiert (Bruhn/Georgi 2006). Dabei verstand man Transaktionen zunachst als diskrete (voneinander unabhangige) Ereignisse, spater auch als relationale Phanomene (Bruhn 2002a; 2002b). Die Marketingtheorie und -praxis vernachlassigte (mit wenigen Ausnahmen) jedoch, Interaktionen zwischen Konsumenten zu analysieren. Gerade Begegnungen zwischen Individuen beeinflussen jedoch deren Wahrnehmung, Beurteilung und Akzeptanz von Produkten und Marken (Bearden/Etzel 1982). Die isolierte Betrachtung des Konsumentenverhaltens als Entscheidung Einzelner ist daher um Einflusse…

A branch-and-price framework for decomposing graphs into relaxed cliques

2021

We study the family of problems of partitioning and covering a graph into/with a minimum number of relaxed cliques. Relaxed cliques are subsets of vertices of a graph for which a clique-defining property—for example, the degree of the vertices, the distance between the vertices, the density of the edges, or the connectivity between the vertices—is relaxed. These graph partitioning and covering problems have important applications in many areas such as social network analysis, biology, and disease-spread prevention. We propose a unified framework based on branch-and-price techniques to compute optimal decompositions. For this purpose, new, effective pricing algorithms are developed, and new…

Mobile social networking in theory and practice

2008

Mobile social networks have gained the attention of the media, academy and mobile market. Despite of the robust tradition of network and community studies, mobile social networks are often addressed improperly. This paper presents a theoretical framework to study mobile social networking and examines the design implications of results of an exploratory study conducted with a group of 18 young adults in Finland. The findings of this study indicate that the quality of mobile applications offering social networking could be greatly increased by integrating the knowledge of two traditions that so far developed in parallel, namely the mathematical as well as social approaches to social networks.

Evaluation of Structural and Temporal Properties of Ego Networks for Data Availability in DOSNs

2017

The large diffusion of Online Social Networks (OSNs) has influenced the way people interact with each other. OSNs present several drawbacks, one of the most important is the problem of privacy disclosures. Distributed Online Social Networks (DOSNs) have been proposed as a valid alternative solution to solve this problem. DOSNs are Online Social Networks implemented on a distributed platform, such as a P2P system or a mobile network. However, the decentralization of the control presents several challenges, one of the main ones is guaranteeing data availability without relying on a central server. To this aim, users’ data allocation strategies have to be defined and this requires the knowledg…

Towards better privacy preservation by detecting personal events in photos shared within online social networks

2015

Today, social networking has considerably changed why people are taking pictures all the time everywhere they go. More than 500 million photos are uploaded and shared every day, along with more than 200 hours of videos every minute. More particularly, with the ubiquity of smartphones, social network users are now taking photos of events in their lives, travels, experiences, etc. and instantly uploading them online. Such public data sharing puts at risk the users’ privacy and expose them to a surveillance that is growing at a very rapid rate. Furthermore, new techniques are used today to extract publicly shared data and combine it with other data in ways never before thought possible. Howeve…

The Role of Social and Collaborative Networks in the Development of in-House Multimedia Language Learning Materials

2012

The development of in-house language learning materials has being going on for many decades. In the past, it was difficult for language teachers worldwide to share their in-house materials with other teachers, and so was having access to the materials developed by others. This often produced a feeling of isolation and, very frequently, provoked a duplication of efforts and a bigger investment of time. However, thanks to the Web 2.0 teachers and practitioners worldwide can communicate with each other and share experiences and materials. While this aspect of the so-called Social Web has being successfully exploded in the past few decades, especially in the case of online communities of teache…

Electronic word of mouth (eWOM) in tourism

2012

This paper is based on the idea that user generated contents (UGC) about holidays, travels and destinations, widely propagated throughout modern social networks, have a topical relevance respect to the diffusion of the image of tourist destinations. More than other information transmission mechanisms, word of mouth (WOM) strongly influences consumer behavior and decision-making, especially when ‘experience goods’ (as in the case of tourism) difficult to be evaluated before their consumption are concerned (Wilson 1994; Griffin 1995; Silverman 1997; Rosen 2002; Dall’Ara, 2002; Lambin, 2004). The advances of ICT tools and the emergence of the Internet strongly influence word of mouth, since la…

Empirically-derived subgroups of Facebook users and their association with personality characteristics: a Latent Class Analysis

2018

Abstract In recent years, considerable research effort has been directed at the identification of relationships between psychological variables and Facebook usage indicators. However, the identification of homogeneous subgroups of individuals based on similar Facebook usage characteristics still presents a challenge. This study aims: (1) to empirically determine homogeneous groups of Facebook users based on variables regarding their personal experience on Facebook, by using a Latent Class Analysis; and (2) to examine the association between an individual's personality and interpersonal characteristics and the empirically-derived profiles of Facebook usage. Eight hundred and eleven Facebook …
