Full textAbstract:
The capacity for online learning environments to provide quality learning experiences for students has been the focus of much speculation and debate in the higher education sector from the late 1990s to the present day. In this area, 'quality' has become synonymous with engaging students in a learning community. This study reports on a qualitative research project designed to explore the significance of community for students when they study in online learning environments. This project used three case studies to explore tertiary students' thoughts and expectations about community in the online environment. The research was constructed iteratively. Data from the initial case suggested the need to explore the relationship between the constructed online learning environment and the development of learning communities or what I have termed Social Learning Support Networks (SLSN). To explore this issue further, the project was expanded and subsequent cases were chosen that included fundamentally different types of online learning environments. The project had two significant results. Firstly, students not only confirmed popular educational theories on the value of learning communities, but also described how this form of social connection might practically benefit their learning. Secondly, the project found that certain forms of synchronous online environments provided enhanced opportunities for students to form social connections that supported their learning. This project provides new evidence of the benefit of community for students studying online and argues that future online learning environments should be shaped by five key principles designed to foster a sense of social connection between students.

Online communities have grown to be an important feature of modern life, and substantial economic assets in their own right. Over the years, organizations that provide them have adopted a range of management practices, or policies. We propose that the choice of policies to manage an online community can be viewed under the lens of mechanism design. Using both empirical data and computer simulations, we investigate how online community providers might decide to put in place and evaluate such mechanisms.

Full textAbstract:
Malaria is the main cause of mortality for children under the age of 5 in Burundi. The access to malaria diagnostics and treatment is hampered not only because of logistical issues, but also due to the lack of qualified human resources and their inequitable distribution across the country. To mitigate the lack of human resources for health, the government of Burundi, along with its partners, shifted some tasks to community health workers (CHWs) to cover unmet healthcare needs for selected diseases such as malaria, diarrhea, and pneumonia. The purpose of this study was to determine whether the social support provided to CHWs had an impact on morbidity due to malaria for children under the age of 5. The social networks and social support theoretical framework was used to explore the type of social support received by CHWs and its impact on the number of children treated. The 88 CHWs who participated in this cross sectional survey, were randomly selected from a pool of 719 CHWs who were part of a pilot project that was implemented in the districts of Gahombo, Gashoho, and Mabayi, from 2011 to 2014. The study findings showed mixed results with a positive correlation between the instrumental support received and the number of children under the age of 5 treated. However, a statistically significant correlation was not established between the emotional, informational, and appraisal support received and the number of children under the age of 5 treated. The positive social change implications of the study include providing evidence to build and enhance human resource capacity for improving the health of children living in Burundi, an under-resourced country, through the development of a support package that can be offered to CHWs to help them perform their duties in a more effective way.

Full textAbstract:
Thesis (MBA)--Stellenbosch University, 2011.<br>The purpose of this study is to identify the user features for an online sports community network.
Social networks sites are on a rapid increase. Designers of these sites need to consider what
features are critical to optimally facilitate their users’ behaviour on these sites. This identification of
features will seek to enhance the growth and development of a site’s social communities and allow
for its ultimate success.
This study focuses on establishing the social networking ecosystem by identifying the role of social
networks in society, the user behaviour trends on social network sites and the key features
required for a social network site. Furthermore, the study establishes the role of sports fans in
society and digital trends for online sports fans visiting sports sites.
This study met the research objectives from the findings gained from relevant literature and the
employment of an empirical research study. The latter was carried out by means of an online
questionnaire targeting an audience that qualified to be both social media lovers and online sports
fans.
The research disclosed fundamental findings with regards to the user behaviour and frequency of
usage of both social network sites and sports sites. Specifically, it was determined that the
technological behaviours in the social technographic profile for online users were aligned to those
of the social technographic profile for social media lovers and online sports fans. Consequently, the
key features of social network sites and most frequently-used features on sports sites could be
used to identify the features required for an online sports community network.
The main conclusion drawn from this research was a list of features required for a sports
community network. These features were determined for the initial launch phase of a sports
community network. Enhancement and development of new features would be required to facilitate
the user requirements as the site grows. It is therefore important for the success of the sports
community site that the owners or designers continuously review the user requirements and adapt,
enhance and develop features as the site gains traction.
This research study recommends that the list provided be used for the initial design and launch
phase of an online sports community network. This list should be constantly evaluated from a usercentric
perspective as the site grows.

Full textAbstract:
Online communities have become an increasingly popular channel for social interaction, enabling knowledge and opinion sharing across a board range of topics and contexts. Their viability and sustainability depends largely on contributions from community members in terms of time, resources, and knowledge. However, how individuals' knowledge contribution behavior changes over time and what network structural characteristics influence individuals' contribution behavior is not well understood. This study investigates "co-evolution" of social networks (i.e. advice network) and knowledge contribution behavior thorough a lens of social selection and social influence mechanism. This study are particularly interested in examining the dynamics of the advice network ties and the knowledge contribution behavior in the context of virtual financial communities in which people voluntarily participate to exchanges investing-related information. Unlike popular friendship-based online social networks, virtual financial communities in this study enables members to construct their own advice network by adding, maintaining, or terminating advice ties. Changes in network ties are referred to as social selection, while changes in individuals' behavior in response to the current network position are referred to as social influence. Dynamic network modeling is applied to investigate effects of social selection and influence separately and then examine the interplay between social selection and behavioral influence. Examination of such effects both separately and simultaneously requires a longitudinal data that capture dynamic changes in both the advice ties and the behavior under study.

1 EINLEITUNG
Laut der ARD-Media-Studie 2011 liegt die Internetdurchdringung in Deutschland bei 74,4%. Erwachsene Onliner, welche gelegentlich bis regelmäßig im Netz sind, kommen auf eine Verweildauer von täglich 137 Minuten an 5,6 Tagen pro Woche [ARD2011]. Jede fünfte Minute im Internet wird auf Social-Media-Plattformen, wie Twitter, Xing oder Wikipedia, verbracht. Zwei der weltweit meistbesuchten Websites gehören zu den Social Media: Facebook und YouTube [PWC2012]. Durch die steigende Nutzung des Internets eröffnen sich Unternehmen Möglichkeiten, welche zur Wertschöpfung in den verschiedenen Unternehmensbereichen, beispielsweise der Marketingabteilung, Human Ressources sowie der internen und externen Prozessoptimierung, genutzt werden können [Parpart2009]. Eine intensive Nutzung der Social Media erzeugt allerdings auch einen immer weiter ansteigenden Daten- und Kommunikationsverkehr. Das wachsende Datenaufkommen aufgrund zunehmender Nutzerzahlen und immer größeren Anwendungen im Internet erfordert eine Aufstockung der Ressourcen im IT-Bereich, welche zum einen Kosten verursachen und zum anderen nicht permanent benötigt werden [ITM2011]. Social Media stellen demnach nicht nur die Marketingabteilungen vor neue Herausforderungen, sondern auch das IT-Service-Management. Beide Bereiche versuchen dem mit entsprechenden Monitorings entgegenzutreten und optimale Ergebnisse zu erzielen. Aufgrund von Daten werden Analysen erstellt und Beobachtungen sowie Vorhersagen getroffen. Diese Monitoringkonzepte gewinnen heutzutage immer mehr an Bedeutung für die Unternehmen, jedoch ist es heute übliche Praxis, dass jede Abteilung, unabhängig von anderen Bereichen, individuelle Monitoringkonzepte und Datenbankmanagementsysteme aufstellt und betreibt. Im Rahmen des vorliegenden Beitrages wird untersucht, wie sich diese derzeit etablierten Lösungen im Sinne eines gesamtheitlichen Ansatzes erweitern lassen und damit die Qualität des Monitorings und darauf aufsetzend möglicher Prognoseverfahren verbessert wird. Im Fokus der Untersuchung stehen dabei die Daten auf Basis von User Generated Content im Web 2.0. Diese Arbeit schlägt ein Konzept vor, wie die Daten aus verschiedenen Quellen kombiniert und aggregiert werden können. Zum einen wird gezeigt, welches Potential eine solche Datenintegration für die Steuerung des IT-Betriebs bietet, zum anderen, wie aktuelle Anwender von Social-Media-Monitoring von einer solchen Integration profitieren können. In einem Ausblick werden aktuelle Forschungsaktivitäten, welche sich aus der aufgeworfenen Problemstellung ableiten, diskutiert.

Full textAbstract:
Rural Internet connectivity projects aimed at bridging the digital divide have mushroomed across many developing countries. Most of the projects are deployed as community centred projects. In most of the cases the initial deployment of these projects is funded by governments, multilateral institutions and non-governmental organizations. After the initial deployment, financial sustainability remains one of the greatest challenges facing these projects. In the light of this, externally funded ICT4D interventions should just be used for “bootstrapping” purposes. The communities should be “groomed” to take care of and sustain these projects, eliminating as soon as possible a dependency on external funding. This master thesis presents the design and the implementation of a generic architecture for the management of the costs associated with running a computer network connected to the Internet, The proposed system, called the Network Revenue Management System, enables a network to generate revenue, by charging users for the utilization of network resources. The novelty of the system resides in its flexibility and adaptability, which allow the exploration of both conventional and non-conventional billing options, via the use of suitable ‘adapters’. The final goal of the exploration made possible by this system is the establishment of what is regarded as equitable charging in rural, marginalized communities - such as the community in Dwesa, South Africa.

Orientador: Prof. Dr. Klaus Frey<br>Tese (doutorado) - Universidade Federal do ABC, Programa de Pós-Graduação em Planejamento e Gestão do Território, Santo André, 2018.<br>A presente tese de doutorado em Planejamento e Gestão do Território está baseada em uma pesquisa de tipo dedutivo, que partiu do contexto geral da gestão de riscos de desastres e dos processos de geração de resiliência, os quais são analisados como um fenômeno social a partir da concepção teórica da governança recorrendo à metodologia de Análise de Redes Sociais (ARS). Este contexto geral é analisado por meio do estudo de caso sobre o programa "Iniciativas com Participação Comunitária" na gestão de riscos de desastres na Bacia Hidrográfica Chiguaza, San Cristóbal, Bogotá. A pesquisa buscou desenvolver uma reflexão teórica sobre a governança na gestão de riscos e a resiliência, indagando sobre o papel do Estado e as organizações sociais e comunitárias. A pesquisa se aprofundou sobre os processos sociais que permitem a construção da resiliência e como as organizações sociais estão organizadas e participam das redes de governança, contribuindo a alcançar a sua finalidade.
Como resultado final a pesquisa encontrou quatro fatores que interferem na construção social da resiliência. O primeiro é a gestão de riscos na perspectiva da governança envolvendo relações sociais caracterizadas por complexidade, diversidade e dinamismo. O segundo fator se refere aos arranjos institucionais e sua relação com a formação de estruturas sociais em um contexto de descentralização e coordenação multiescalar. O terceiro consiste na vontade política dos diferentes governos em potencializar as estruturas sociais. O quarto se refere à percepção social do risco na qual se identifica a necessidade de relação entre a produção social da ameaça, vulnerabilidade e exposição. Esses fatores influenciam a resiliência em cidades onde o objetivo é reduzir riscos, aumentar a participação dos cidadãos na gestão ambiental e adaptar-se às condições de variabilidade climática resultantes das mudanças climáticas.<br>The present doctoral thesis of the Territory Planning and Management Program was based on a deductive type of research, where the general context of disaster risk management and resilience generation processes were studied, which are analyzed as a social phenomenon from the theoretical conception of governance and the methodology of social network analysis (SNA). This general context is studied through the case study "The Initiatives Program with Community Participation in Disaster Risk Management in The Chiguaza Brook, Locality of San Cristobal Bogota." The research sought to develop a theoretical reflection on governance around risk management and resilience, investigating the role of the State and social and community organizations in the promotion of resilient communities. The investigation deepened on the social processes that allow the construction of resilience and how social and community organizations are organized and participate contributing to reach this purpose.
As a final conclusion four factors could be identified that intervene in the social construction of resilience. The first is risk management as a governance practice being influenced by the complexity, diversity and dynamism of social relations. The second referes to the institutional arrangements that intervene in the creation of social structures based on the context of decentralization and multi-scale coordination. The third is the political will of the different governments to strengthen social structures. The fourth concerns the social perception of risks in which the need to identify the relationship between the social production of the threat, vulnerability and exposure arises. These factors influence resilience in cities where the aim is to reduce risks, increase citizen participation in environmental management and adapt to the conditions of climatic variability resulting from climate change.

Full textAbstract:
Community networks (in South Africa and Africa) are often serviced by limited bandwidth network backhauls. Relative to the basic needs of the community, this is an expensive ongoing concern. In many cases the Internet connection is shared among multiple sites. Community networks may also have a lack of technical personnel to maintain a network of this nature. Hence, there is a demand for a system which will monitor and manage bandwidth use, as well as network use. The proposed solution for community networks and the focus within this dissertation, is a system of two parts. A Community Access Point (CAP) is located at each site within the community network. This provides the hosts and servers at that site with access to services on the community network and the Internet, it is the site's router. The CAP provides a web based interface (CAPgui) which allows configuration of the device and viewing of simple monitoring statistics. The Access Concentrator (AC) is the default router for the CAPs and the gateway to the Internet. It provides authenticated and encrypted communication between the network sites. The AC performs several monitoring functions, both for the individual sites and for the upstream Internet connection. The AC provides a means for centrally managing and effectively allocating Internet bandwidth by using the web based interface (ACgui). Bandwidth use can be allocated per user, per host and per site. The system is maintainable, extendable and customisable for different network architectures. The system was deployed successfully to two community networks. The Centre of Excellence (CoE) testbed network is a peri-urban network deployment whereas the Siyakhula Living Lab (SLL) network is a rural deployment. The results gathered conclude that the project was successful as the deployed system is more robust and more manageable than the previous systems.

Full textAbstract:
Remote communities stay vulnerable in the face of major socioeconomic challenges. Tourism is often seen as a way to stimulate local economies and increase attractiveness of peripheral destinations, while events are considered to be one of the tools to promote tourism. In this regard, local collaboration is deemed to be crucial for facilitating development in spatially remote areas, where social context plays an important role in formation of entrepreneurial networks. By using the case of a local community festival Aldrei fór ég suður (AFS) in Ísafjörður, Iceland, I investigate relationship between the festival and local tourism entrepreneurs and define opportunities that the festival might provide for sustainable development of the area. Based on data collected from 24 interviews, findings suggest that the impact of AFS on local businesses varies depending on the category of business, its location, seasonality and target group, whereas the festival also contributes to enhancement of destination image, extension of tourist season and attraction of new categories of visitors. Following theoretical framework of social capital and social embeddedness, the main role of the festival is found to be related to enhancement of community pride and contribution to social change within community. On the other hand, results demonstrate general lack of willingness to collaborate and suggest an increased risk of overembeddedness given the self-reliant nature of the festival and its reluctance to commercialization. Discussed suggestions for sustainable destination development include co-branding, packaging for extended stay, transportation options and usage of empty housing for temporary accommodation.

Full textAbstract:
An exploration of the relationship between patterns of social interaction and social work practice which incorporates thirteen publications. The thread running throughout is the way in which new forms of social care practice are made possible by cross-boundary linkages. A 'Critical Review' sets the context and analyses the works. This is followed by the first published work which applies anthropological models to the study of social marginalisation. The second publication introduces the social network concept and investigates patterns of reciprocity and dependency in social care. The next section of the thesis consists of a 'commentary' on the Griffiths and Wagner Reports. This is followed by a closely related work arguing that there is a fundamental opposition between market and network models of social and community care. The thesis then looks at the ways the culture concept can be used to illuminate the cross-boundary practices associated with community care. The concept of culture and its relationship to cross-boundary working is developed more fully in the next section where it is argued that collaboration culture is paradoxical because it incorporates both respect for difference and a commitment to collective action and that resolving this paradox through collaborative work is a complex and skilled activity. The next section introduces a comparative dimension and suggests that studies of collaboration could be based on looking at the ways in which modern welfare systems try to solve the problem of potential fragmentation and lack of coherence. The work which follows on from this makes use of discourse analysis and network analysis to compare and contrast the rhetoric of partnership and collaboration with the way in which individuals think about their day-to-day cross-boundary work. This raises questions about the changing nature of working relationships in the field of social care and is followed by an investigation into the nature and effects of globalisation on social work in Europe. 'The Co-operation Concept in a Team of Swedish Social Workers' is an attempt to develop a cross-national framework for the analysis of community care focused on the cross-boundary networks of a team of hospital based social workers in Stockholm. The thesis then returns to somewhat broader concerns by means of a work which investigates the contribution of theories of social interaction to theories of social work. These concerns permeate the penultimate section on networking but in a more applied and specific way. The book which constitutes this section of the thesis argues that there is a distinctive theory of networking and that it can be applied to the whole range of social welfare and social care specialisms. The final work explores the impact of globalisation on the ways in which social workers currently experience their roles and develop their sense of professional identity.

Full textAbstract:
A network structure is becoming an omnipresent determinant in the organization of social and economic life. In a sense, a network outlines, encompasses, structures, and arranges the space of data, information, services, goods, things and people, and how they flow. However, a network is not able (neither is its aim) to organize a given space in the traditional, vertical arrangement. It is not an equivalent of flat structures, either; it is rather an energy and information entity applied in a given space (the territory, the area, the logistics of an enterprise) which, by playing on continuities and non-continuities, accelerates the exchange and commercialization of ideas (innovations, research, cooperation, joint services, projects and ventures). In the era of the multiplication of various network entities, it is more and more difficult to identify them, e.g. according to the criteria of key values. In addition, we more and more often deal with the phenomenon of pullulating overlapping pervasion, a takeover and interference of networks which for an average citizen gives a very blurred picture of reality (e.g. Tesco, IKEA, OBI, Kaufland; and their own-brand products which do not have the name of an individual manufacturer). This paper has the model character and presents a model of a Knowledge-based Opole Tourism Cluster (OKTW) as a network proposal for arranging the “knowledge-based” space of the Opole region in Poland. So far it hasn’t been possible to do empirical researches because OKTW is still in the process of creation.

Full textAbstract:
Many applications can be modeled intuitively as graphs, where nodes represent the entities and the edges the relationships between them. This way, we are able to better understand them and how they interact.
One particularity of these graphs is that their entities are organized in modules called communities. A community is informally defined as a set of nodes more densely connected internally than externally. For instance, in the case of a social network, persons with similar characteristics are grouped forming communities.
Community detection has become a hot topic in the research community during the last years, due to its amount of applications. For instance, in social networks, communities give information about the persons forming them, by just looking at the relationships linking them. This is used in directing marketing campaigns, recomendation systems or in link prediction.
Because of the relevance of the problem, many community detection algorithms exist, which follow different strategies. Most of them are based on the well known modularity metric, though other techniques based on random walks and epidemics spreading also exist. The problem of existing algorithms is that they have been designed to be generic, completely ignoring the particularities of the graphs belonging to different domains. As a result and under certain circumstances, these algorithms tend to find groups of nodes with a lack of a community structure.
This thesis, overcomes this issues by proposing a novel community detection algorithm design methodology, called Domain Specific Community detection. This methodology is based on defining a set of structural properties communities of a given domain should fulfill, as well a set of behavioral properties to be fulfilled by a community detection algorithm or metric. Based on this methodology, we propose a set of properties for the specific domain of social networks, consisting of three structural properties (Internal structure sensitive, Bridges resistant and Cut-Vertex resistant) and three behavioral properties (Scale independent, Adaptive and Lineal community cohesion).
Based on the aforementioned properties, we design a novel community detection metric, called the Weighted Community Clustering (WCC), which takes the presence of a triangle as an indicator of a strong relation between two persons in a social network. We formally prove that WCC fulfills the proposed properties, thus guaranteeting that communities resulting from maximizing WCC have a minimum degree of quality. Moreover, we prove this last statement by performing an empirical analysis on communities from real graphs, showing that WCC is able to correclty rank these well.
In this thesis we also propose an algorithm called Scalable Community Detection (SCD), based on the maximization of WCC. SCD is also designed with parallelism in mind, in order to take advantage of current many-core architectures. We show that SCD is to detect communities with an unprecedented quality, being its execution time faster than most of existing proposals, being able to process billion edge graphs in a few hours
This thesis also includes a statistical study about the structural characteristics of the meta-groups found in several real graphs, comparing these to graph from two different synthetic graph generators. We show that communities produced by a synthetic graph generator commonly used in community detection research are very dissimilar to those found in real graphs.
Finally, this thesis includes a study on how to implement a triangle counting algorithm on a modern many core architecture, more concretely the Intel Single Chip Cloud Computer (Intel SCC).<br>Moltes aplicacions reals es poden modelar de manera intuïtiva mitjançant grafs. on els nodes representen entitats de la xarxa, i les arestes les relacions entre aquestes. D'aquesta manera som capaços d'entendre en detall com les entitats interactuen. Una de les particularitats d'aquests grafs, és que les entitats que els conformen s'organitzen mitjançant comunitats. Una comunitat es defineix informalment com a un conjunt de nodes amb un nombre d'arestes internes molt més gran que les que hi ha entre els nodes de la comunitat i la resta de nodes del grat. Per exemple, en el cas d'una xarxa social, persones amb característiques similars s'agrupen en comunitats. La cerca de comunitats ha adquirit un gran interès en la comunitat científica durant els darrers anys, degut a la infinitat d'aplicacions que tenen. Per exemple, en una xarxa social, les comunitats ens donen informació sobre les persones que les formen, tan sols mirant les relacions que les uneixen. Això s'usa, per exemple, per dirigir campanyes de màrqueting, recomanar productes, predir qui es connectarà amb qui, etc. Degut al seu interès, existeixen una gran quantitat d'algorismes per a la cerca de comunitats en xarxes. Els mes coneguts son aquells basats en una mètrica anomenada modularitat, tot i que també n'hi ha basats en camins aleatoris, o en processos epidèmics. El problema d'aquests algorismes es que estan pensats per a ser genèrics, ignorant les particularitats que conformen cada tipus xarxa. Com a resultat, ens trobem en que sota certes circumstancies, la seva qualitat se’n veu penalitzada, tot trobant conjunts de nodes que no poden ser considerats comunitats. Aquesta tesi proposa una metodologia alternativa, anomenada "disseny específic del domini", alhora de dissenyar algorismes i mètriques per a la cerca de comunitats. La metodologia es centra en definir quines propietats estructurals haurien de tenir les comunitats en una xarxa d'un domini concret, i un seguit de propietats de comportament que haurien de complir els algorismes que les troben. En el nostre cas, ens centrem en les Xarxes socials, i definim tres propietats estructurals (Sensibilitat estructural, Resistència als ponts i Resistència als nodes-tall) i tres propietats de comportament (Adaptiva, Independent de l'escala i Cohesió lineal). Arrel d'aquestes propietats, proposem una mètrica, anomenada Weighted Commuity Clustering (WCC), que ens qualifica com de bona és una classificació de nodes d'un graf en comunitats. La mètrica fa us del triangle com a indicador bàsic de la presència d'una relació forta entre dues persones d'una xarxa social. Es demostra formalment que la mètrica compleix les propietats esmentades, garantint així uns mínims de qualitat, a diferencia de les propostes de l'estat de l'art. Tanmateix, mitjançant un anàlisi empíric, demostrem que les comunitats amb un alt WCC tenen unes característiques estructurals esperades en una bona comunitats per a xarxes socials. Aquesta tesi també proposa un algorisme de cerca de comunitats basat en el WCC, anomenat Scalable Community Detection (SCD). A mes a mes, per tal d'aprofitar els darrers avenços en microprocessadors, l'algorisme esta dissenyat per ser inherentment paral·lel. Demostrem mitjançant una sèrie de grafs reals socials, que SCD es capaç de detectar comunitats amb una qualitat sense precedents, sent un dels algorismes mes ràpids capaç de trobar comunitats en grafs de milers de milions d'arestes en poques hores. La tesi també inclou un estudi estadístic de les característiques estructurals que tenen els grups que formen les entitats en diversos grafs reals, i les comparem amb grafs generats sintèticament per tal de validar la correctesa dels seus generadors, mostrant que alguns d'aquests últims disten molt d'assemblar-s'hi. Finalment es realitza un estudi de com implementar el comptatge de triangles en grafs, en una arquitectura many-core

I denne masteroppgaven implementeres og testes to algoritmer for å finne gruppe- struktur i nettverk, nemlig Louvain-metoden og Diffusion and Propagation-metoden. Et nettverks gruppestruktur består av en naturlig inndeling av nettverkets noder i ikke-overlappende sett, der hvert sett består av noder som er tettere koblet til hver- andre, enn til resten av nettverket. De ovennevnte algoritmene er to alternativer blant mange gode iterative teknikker som har sett dagens lys i løpet av de siste 15 årene.Vi presenterer tre endringer til metodene nevnt over. Først introduserer vi en tredje fase i Louvain-metoden, og endrer dens aggregerende natur ved å la metoden bryte opp grupper i tillegg til å slå dem sammen. Videre undersøker vi hva som skjer med den beregnede gruppestrukturen når matrisen som representerer det un- derliggende nettverket gjennomgår en av flere matrisetransformasjoner. Spesifikt er vi interesserte i se på transformasjoner der kantmatrisen til nettverket opphøyes i andre og tredje potens, samt matriseeksponentialet. Til slutt tester vi og sammen- ligner resultatene til metodene på genererte nettverk av ulike slag, samt to store sosiale nettverk med millioner av noder fra den virkelige verden.

Full textAbstract:
Un réseau social est une structure composée d'entités reliées par un ou plusieurs types d'interdépendance, le plus souvent modélisé par un ou plusieurs graphes. Une caractéristique importante des réseaux sociaux est leur structure en communautés. Une communauté est définie comme un ensemble de nœuds qui interagissent d'avantage entre eux qu'avec le reste du réseau. Cette thèse porte sur l'analyse des communautés dans les réseaux sociaux, qui est utile pour de nombreuses tâches, telles la caractérisation de la structure, les systèmes de recommandation, la visualisation, ou encore le suivi de la dynamique. Nous proposons notamment des techniques pour découvrir les communautés dans les graphes bipartites, basé sur l'optimisation de modularités bipartites. Nous étudions ensuite la détection de communautés dans les graphes dont les nœuds sont associés à des attributs, comme cela est très souvent le cas dans les applications réelles. Nos algorithmes considèrent simultanément la structure et les attributs du graphe et détectent des communautés telles que les nœuds dans la même communauté soient densément connectés et portent des attributs proches. Les méthodes développées sont appliquées à l'analyse des communautés du site web social Skyrock et de réseaux de blogs, dans le cadre du projet ANR ExDEUSS CEDRES. Nous étudions aussi la contribution des informations extraites des communautés pour améliorer la performance des systèmes de recommandation. Enfin, nous proposons un modèle génératif de réseau social intégrant les attributs de nœuds et la structure des communautés, qui nous permet de proposer des jeux de tests artificiels simulant des réseaux complexes réels.

Full textAbstract:
In this thesis the ideas of network analysis are applied to systems of group living animals. A method of constructing a network of associations by combining group memberships is presented. Methods of filtering the network according to association strength are discussed. . The detection and understanding of community structure within animal social networks forms an important part of this thesis. By allowing the researcher to study (and verify the statistical significance of) intermediate scale structure in the network an insight into the biological processes which may motivate the structure can be obtained. The various methods which have been proposed to detect community structure in networks are reviewed. The use of simulated annealing to detect the structure is discussed. This technique offers the greatest sensitivity in detecting communities, making it very suitable for the detection of the subtle structures that may exist in the constructed network. Two case studies of group living animals are considered: a population of wild guppies and a population of Galapagos Sea lions. In both systems statistically significant community structure is found. The biological processes underlying the observed structure are discussed. In the latter part of this thesis some methods of constructing model networks with realistic community structure are discussed. Inspired by the biological aspects of the earlier part of the thesis; these offer methods of building networks in which the size, strength, and number of communities can be controlled by the researcher.

Full textAbstract:
Community detection in networks is an important area of current research with many applications. Finding community structures is a challenging task and despite significant effort no satisfactory method has been found. Different methods find different communities in the same network and with different computational requirements. To counter this problem, several different methods are often used and the results compared manually. In this thesis, we present three different methods to instead merge the results from different methods (or several runs from the same algorithm) to find better estimates of the community structure. Another problem in practical applications is noisy and imperfect networks with missing and false edges. These imperfections are natural results from the methods used to map the network structure and are often difficult to eliminate. In this thesis, we apply a Monte Carlo-sampling method in combination with the introduced methods for merging community detection results to find community structures in such networks. The method is tested by simulation studies on both real-world networks and synthetic networks with generated uncertainties and imperfections. We finally demonstrate how it is possible to generate confidence levels of the obtained community structure from the merging methods. This allows for a qualitative comparison of the robustness and significance of the network clustering.<br>Identifikation av grupperingar i nätverk är ett viktigt område inom aktuell forskning med många olika tillämpningsområden. Att finna grupperingar är ofta svårt och trots betydande ansträngningar har ingen tillfredsställande metod hittats. Olika metoder finner ofta olika grupperingar i samma nätverk och kräver varierande beräkningskraft. För att hantera dessa problem används ofta flera metoder vartefter resultaten jämförs manuellt. I detta examensarbete presenterar vi tre olika metoder att istället slå samman resultat från olika metoder (eller fler körningar från samma algoritm) för att hitta bättre uppskattningar av grupperingarna. Ett annat problem i praktiska tillämpningar är brus och ofullständiga nätverk med saknade och falska kanter. Dessa brister är naturliga resultat från de metoder som används för att kartlägga nätverketstrukturen och det är ofta svåra att eliminera dessa. I detta examensarbete använder vi Monte Carlo-metoder i kombination med de introducerade metoderna för att slå samman funna grupperingar för att hitta grupperingar i det osäkra nätverket. Vi testar metoden genom simuleringstudier på både verkliga och syntetiska nätverk med genererade osäkerheter och brister. Slutligen demostrerar vi hur det är möjligt att skapa konfidensnivåer för noder i grupperingar med hjälp av metoderna för sammanslagning. Detta möjliggör en kvalitativ jämförelse av stabilitet och signifikans av identifierade nätverksgrupperingar.

Full textAbstract:
This thesis consists of two parts: Part I (Chapters 2 and 3) critically assesses a set of methodological tools that are widely used in the literature and that are applied to the empirical analysis in Part II (Chapters 4 and 5). Using a randomised experiment, the first chapter compares pen-and-paper interviewing (PAPI) with computer-assisted personal interviewing (CAPI). We observe a large error count in PAPI, which is likely to introduce sample bias. We examine the effect of PAPI consumption measurement error on poverty analysis and compare both applications in terms of interview length, costs and respondents’ perceptions. Next, we formalise an unproven source of ordinary least squares estimation bias in standard linear-in-means peer effects models. Deriving a formula for the magnitude of the bias, we discuss its underlying parameters. We show when the bias is aggravated in models adding cluster fixed effects and how it affects inference and interpretation of estimation results. We reveal that two-stage least squares (2SLS) estimation strategies eliminate the bias and provide illustrative simulations. The results may explain some counter-intuitive findings in the social interaction literature. We then use the linear-in-means model to estimate endogenous peer effects on the awareness of a community-based development programme of vulnerable groups in rural Tanzania. We denote the geographically nearest neighbours set as the relevant peer group in this context and employ a popular 2SLS estimation strategy on a unique spatial household dataset, collected using CAPI, to identify significant average and heterogeneous endogenous peer effects. The final chapter investigates social network effects in decentralised food aid (free food and food for work) allocation processes in Ethiopia, in the aftermath of a serious drought. We find that food aid is responsive to need, as well as being targeted at households with less access to informal support. However, we also find strong correlations with political connections, especially in the immediate aftermath of the drought.

Full textAbstract:
Maximizing Influence (IM) in social networks has a considerable role to play in the phenomenon of viral marketing, targeted advertisements and in promoting any campaigns. However, the Influence Maximization Problem is a very challenging research-problem due to it being NP-Hard and scaling with the social networks with millions of nodes and edges becomes very tough due to the computational complexities concerned with it. Recently, solving this problem through the use of community detection based methodology is becoming very popular since, it reduces the search space by dividing the network into smaller and more manageable groups called "communities." As part of the larger research work, we reiterate a framework which has been inspired by collection of different work done by Alfalahi et al. (2013) that we can implement to solve the IM problem and its limitation through community detection and fuzzy logic inspired approach. Since the work is still under development, for this project, we report on understanding the IM field through literature reviews and in communicating a design of IM framework as inspired by the previous works. We also present our version ofthe blueprint (Algorithm design) of the framework as a five step approach. For the purpose of this report, we implement and evaluated the step 1 and step 2 of the framework. Step 1 is about preprocessing the input network with a similarity measure, which according to previous study by Alfalahi et al. (2013a) aids the algorithms in detecting better community structure (clear and accurate distinction of the nodes into communities in networks). We test it to see if it holds true. Step 2 is about implementing the community detection in social network. We benchmarkthree candidate algorithms, chosen based on theirperformance, from the previous studies in community detection fieldand we report onwhich algorithm should we consider to use in the proposed framework through experimentationon the simulated data. We use Normalized Mutual Information (NMI) and Modularity (Q) as evaluation metrics to measure the accuracy of the community detected by the candidate algorithms. Our results show that similarity based preprocessing does not improve the community structure and thus may not be required in the framework. We also found out that Louvain should be the algorithm that use to detect communities in social networks since it outperforms both CNM and Infomap on Q and NMI

Full textAbstract:
One in seven people in the world use online social networking for a variety of purposes -- to keep in touch with friends and family, to share special occasions, to broadcast announcements, and more. The majority of society has been bought into this new era of communication technology, which allows everyone on the internet to share information with friends. Since social networking has rapidly become a main form of communication, holes in privacy have become apparent. It has come to the point that the whole concept of sharing information requires restructuring. No longer are online social networks simply technology available for a niche market; they are in use by all of society. Thus it is important to not forget that a sense of privacy is inherent as an evolutionary by-product of social intelligence. In any context of society, privacy needs to be a part of the system in order to help users protect themselves from others. This dissertation attempts to address the lack of privacy management in online social networks by designing models which understand the social science behind how we form social groups and share information with each other. Social relationship strength was modeled using activity patterns, vocabulary usage, and behavioral patterns. In addition, automatic configuration for default privacy settings was proposed to help prevent new users from leaking personal information. This dissertation aims to mobilize a new era of social networking that understands social aspects of human network, and uses that knowledge to honor users' privacy.

This research seeks to identify, describe, and understand community as it is expressed in the local and urban gardening sphere of Tucson, Arizona. Underlying this effort is the ethnographic intent to qualitatively document and explore whether, and ultimately how, members or components of the social network interact. The relevance of this research lies not only in better understanding how people experience community in specific contexts, but also in its aim to demonstrate that both physical and virtual relationships - virtual referring to a conceptualized essence or effect not manifest in concrete appearance or form - contribute to the development, manifestation, and common ownership of communities. Gardening-related and support-oriented resources and spaces in Tucson - namely the Seed Library of the Pima County Public Library and Las Milpitas de Cottonwood Community Farm - served as field sites for this research and represent vertices which link subgroups physically and virtually within the social network itself. Importantly, examining the synergy characterizing relations between members and components of the network aids efforts to qualitative describe the community’s resilience.

Full textAbstract:
Master of Science<br>Department of Landscape Architecture, Regional and Community Planning<br>Stephanie Rolley<br>The City of Emerado, North Dakota, population 414, located in northeast North Dakota is the subject of a Social Network Analysis (SNA), conducted prior to it being the subject of a University of North Dakota Center for Community Engagement, Community Connect Forum. The SNA was developed based on the results of 25 interviews conducted with local residents, elected officials and business owners, using snowball sampling and following grounded theory methods. The interview results were coded and memos were written to aid in the analysis. Social Network data was entered into the Sentinel Visualizer software (FMS Advanced Systems Group) to develop a visual image of the network, including nodes (people, organizations or businesses) and links to illustrate the relationships between nodes. The SNA helps to frame the relationships in terms of bridging and bonding social capital. The SNA provides the ability to mathematically determine the most important nodes to the community social network, using calculations to determine levels of degree centrality, betweenness centrality, closeness centrality, Eigenvalue, and network density. After calculating these elements, categorical descriptions of the top ten individuals for each category are provided. The networks of five individuals are reviewed in depth to aid in comprehending the process of incrementally expanding networks.

Full textAbstract:
Doctor en Ciencias, Mención Computación<br>En el contexto de la administración de datos para redes sociales, esta tesis aborda sus necesidades de manipulación de datos proponiendo un modelo de datos basado en un conjunto exhaustivo de casos de uso tomados del dominio de las redes sociales (SN, del inglés social networks ), y en el trabajo teórico existente sobre modelos de datos, bases de datos, y lenguajes de consulta.
Un modelo para la administración de datos de redes sociales debe permitir compartir los datos de redes sociales, así como su reutilización e integración, con apoyo para esquemas flexibles y metadatos apropiados para datos con estructura de grafos. El lenguaje de consulta deseado debe proveer la expresividad adecuada bajo límites factibles de complejidad, siendo además accesible y atractivo para los usuarios. Un requisito encontrado frecuentemente en los casos de uso de SN es la necesidad de reestructurar una red, por ejemplo creando nuevos nodos a partir de grupos existentes, o a partir de valores de atributos. Los lenguajes de consulta tradicionales que son capaces de crear valores u objetos suelen tener la capacidad de expresar todas las consultas computables, por lo tanto la evaluación de las consultas se vuelve computacionalmente costosa.
Para abordar estos requisitos se introduce un modelo de datos (SNDM), y un lenguaje de consulta (SNQL). La estructura de de datos utilizada es semiestructurada y está basada en un modelo de triples. SNQL se ha diseñado siguiendo las líneas de lenguajes de consulta ampliamente conocidos, usando como punto de partida una versión de Datalog con una extensión que facilita el cómputo de nuevos valores e identificadores de acuerdo a los requisitos de la manipulación de SN. Dicha extensión se basa en las "second-order tuple-generating dependencies", originalmente propuestas en el contexto de intercambio de datos para capturar la composición de asignaciones entre esquemas.
El lenguaje así definido resuelve, con una complejidad computacional eficiente, los requisitos de los casos de uso típicos del análisis de redes sociales. En efecto, su poder expresivo abarca todas las operaciones de SN relevantes, y su evaluación permanece en NLOGSPACE. Se muestra que las características de este lenguaje satisfacen estas metas demostrando sus propiedades formales y con implementaciones prototípicas del modelo, así como con traducciones desde y hacia a otros modelos.

Full textAbstract:
This thesis work takes an investigative approach into developing a middleware solution for managing services in a community cloud computing infrastructure predominantly made of interconnected low power wireless devices. The thesis extends itself slightly outside of this acute framing to ensure heterogeneity is accounted for. The developed framework, in its draft implementation, provides networks with value added functionality in a way which minimally impacts nodes on the network. Two sub-protocols are developed and successfully implemented in order to achieve efficient discovery and allocation of the community cloud resources. First results are promising as the systems developed show both low resource consumption in its application, but also the ability to effectively transfer services through the network while evenly distributing load amongst computing resources on the network.

Salone, Marci A. "Social Networks and Sense of Community Effects on Psychological Distress Among Community X Residents." ScholarWorks, 2019. https://scholarworks.waldenu.edu/dissertations/6947.
Full textAbstract:
A certain community within the southern region of Texas has consistently been linked to escalating poverty, high crime rates, low educational achievement, and poor physical and mental health. For the purpose of this research, this community will be referred to as Community X. Although some researchers have found that sense of community and supportive social networks are associated with healthy mental and physical functioning, others have suggested that in a debilitated community social networks can facilitate psychological distress and a strong sense of community is difficult to develop. Guided by Bronfenbrenner's ecological model, the purpose of this quantitative correlational study was to examine the combination of 3 Social Network Index (SNI) scores and 4 Sense of Community Index 2 (SCI-2) scores that affect Kessler Psychological Distress Scale (K10) scores. For the 106 Community X resident participants, as the SNI number of embedded networks increased, K10 scores tended to increase, indicating higher levels of psychological distress (consistent with the negative effect research). In a cluster analysis, two clusters emerged in which one cluster (n = 67) had positive z-score means on all SNI indices and all SCI-2 subscales, while the other cluster (n = 39) had all negative z-score means. The cluster with all positive scores had lower K10 psychological distress scores (consistent with the positive effect research), but the difference was not statistically significant. The mixed results indicated that comparative research is needed to control for communities of varying ecological distress to better relate psychological distress to sense of community and the valence of social networks to facilitate positive social change health policies and interventions that are ecological-distress sensitive.

Spiro, Emma S. "Searching for community online: how virtual spaces affect student notions of community." Pomona College, 2007. http://ccdl.libraries.claremont.edu/u?/stc,15.
Full textAbstract:
Social networking sites and virtual spaces have flourished in the past few years. The author explores the impact of such social networking services on the local community at a small liberal arts college. The author investigates modern trends in community theory. Defining community has become more difficult in modern society, where community is no longer easily distinguished by geographical boundaries. From the background of modern community theory the author explores the designation of virtual spaces as “virtual communities.” Literature and research about virtual spaces indicates that they can provide many of the values thought be to inherent to community membership. The strong localized community on campus makes students hesitant in calling Facebook a “virtual community,” despite its strong integration with the face-to-face community itself. Facebook is seen as simply a tool. This thesis incorporates research on one specific case study: through mathematical and ethnographic research of Facebook.com, the author evaluates the opinions of students in considering virtual spaces as communities.

Full textAbstract:
Thesis (M.C.P.)--Massachusetts Institute of Technology, Dept. of Urban Studies and Planning, 2004.<br>"June 2004."<br>Includes bibliographical references (p. 97-105).<br>In recent years, U.S. cities have dramatically increased funding for afterschool activities. These afterschool programs may contribute to community development by expanding social networks, providing new channels for the flow of information and resources to low income neighborhoods. Drawing on research and literature from the fields of sociology, political science and adolescent development, I develop an argument for this hypothesis. The theory is tested using both qualitative data collected from interviews at three case study sites, and quantitative data from surveys distributed to afterschool youth programs in the Boston area. I find that afterschool programs build both bridging and bonding social capital by increasing local and extra-local connections between adolescents and adults, peers, and parents. Policy recommendations designed to increase the social network impact of afterschool programming are provided.<br>by Benjamin Forman.<br>M.C.P.
