Constatada a evolução recente dos modos de vida e as atuais tendências comportamentais dos habitantes das grandes cidades, atribuíveis, em certa medida, à possibilidade de conexão resultante da inserção de mídias no espaço privado da habitação, busca-se, com esse trabalho, verificar a adequação da arquitetura dos apartamentos contemporâneos às demandas advindas desse processo. Estudos sobre as origens da habitação verticalizada e a história das mídias no espaço privado da habitação orientam uma observação empírica cuidadosa da produção de apartamentos, com o objetivo de conhecer mais profundamente os aspectos dessa produção relacionados à definição do espaço construído.

Como resultado do estudo são evidenciados os principais fatores de ordem técnica e projetual que influem na definição do apartamento contemporâneo, relacionando esses fatores ao potencial de flexibilidade do espaço construído. Essa reflexão, fundada no conhecimento dos fatores que determinam a produção atual de apartamentos, constitui subsídio para possíveis redesenhos ou para uma revisão dos critérios de projeto de espaço privado da habitação verticalizada, de modo a possibilitar uma aproximação entre a produção do mercado imobiliário e as demandas do usuário / The recente evolution of the modus vivendi and the current behavior tendencies of urban populations may directly result from the wide networking possibilities offered by a number of new means of communication inserted into private living spaces. Therefore one intends to verify the adequacy of contemporary apartment architecture to such a new media and the resulting user's demands. This work is based upon studies on the origins of high-rise dwellings and on the history of the media in the home, both relying on a meticulous empirical analysis of the apartment buildings production throughout the twentieth century.

As a result one has the evidence of the main technical and projectual factors that define the contemporary apartment, considering the flexibility potential of the built environment. This reflection makes it possible to review project criteria and eventually redesigning private space in high-rise dwellings, in order to help the real estate market production meet the users' demands

It was a transversal, analytical research. Subjects and Methods: The stratified sample was 212 students from a private university that used Facebook, Instagram and/or Twitter. To measure depressive symptoms, Beck Depression Inventory was used, and to measure the dependence to social media, the Social Media Addiction Test was used, adapted from the Internet Addiction Test of Echeburúa. The collected data were subjected for analysis by descriptive statistics where STATA12 was used. Results: The results show that there is an association between social media dependence and depressive symptoms (PR [Prevalence Ratio] = 2.87, CI [Confidence Interval] 2.03–4.07). It was also shown that preferring the use of Twitter (PR = 1.84, CI 1.21–2.82) over Instagram (PR = 1.61, CI 1.13–2.28) is associated with depressive symptoms when compared to the use of Facebook. Conclusion: Excessive social media use is associated with depressive symptoms in university students, being more prominent in those who prefer the use of Twitter over Facebook and Instagram. / Revisión por pares

This project expands root-metaphor analysis by examining the closure of a once popular social networking site, advancing critical interrogation of ownership vs. the idea of online spaces as “communities.” Yahoo! 360° participants used private sphere root-metaphors of home, family, and community constituting a space of intimacy, camaraderie, and care. The closing exposed previously unseen power differentials between participants and Yahoo! Participants reacted by using the metaphor of war and violence to frame the actions of Yahoo!

A web app was developed which allows any internet-connected device to remotely monitor a roadway intersection’s state over HTTP. A mapping simulation was enhanced to allow researchers to retroactively track the location and the ad-hoc connectivity of vehicle clusters. A performance analysis was conducted on the utilized network partitioning algorithm. This work was completed under and for the utility of ETSU’s Vehicular Networking Lab. It can serve as a basis for further development in the field of wireless automobile connectivity.

While organizations have significantly reduced the overt and intentional forms of sex discrimination that impeded women’s careers in the past, a great deal of research suggests women continue to face informal barriers in the workplace. One such arena in which women tend to be disadvantaged is in their workplace networks. In many ways, men and women have similar networks, yet women are less likely than their male counterparts to have personal relationships with high status coworkers. Scholars have long suggested that these strategic connections are valuable and may be especially beneficial to or necessary for women. Networking has long been touted as one way women can overcome workplace disadvantage by strategically developing and/or capitalizing on such networks, which can enable their success and satisfaction at work. However, networking is a considerable investment. Indeed, networking has been called women’s third shift, after work and family responsibilities. As such, it is vital that we understand how women and men can best capitalize on their investments in networking. This research seeks to add to our scholarly understanding by examining the extent to which men and women can translate their networking behaviors into high status connections and capitalize on those connections to enhance their performance and job satisfaction. Results suggest networking behaviors enable men and women to have friends with higher informal status. However, while men’s networking behaviors are related to having higher ranking (formal status) friends, women’s networking behaviors are related to having lower ranking friends. Post-hoc analyses begin to explore the possibility that these gender differences are due to choices made by or others’ reactions to male and female networkers. Results also distinguish between employees’ gender and legitimacy to shed light on how and why men and women can develop and capitalize on high status connections, providing practical implications for employees and organizations seeking to intervene to enable women and men to develop high status connections. This research uses multimethod data to illuminate ways in which both women and men can translate their networking behaviors into high status connections, workplace performance, and job satisfaction.

Packet broadcast networks are in widespread use in modern wireless communication systems. Medium access control is a key functionality within such technologies. A substantial research effort has been and continues to be invested into the study of existing protocols and the development of new and specialised ones. Academic researchers are restricted in their studies by an absence of suitable wireless MAC protocol development methods. This thesis describes an environment which allows rapid prototyping and evaluation of wireless medium access control protocols. The proposed design flow allows specification of the protocol using the specification and description language (SDL) formal description technique. A tool is presented to convert the SDL protocol description into a C++ model suitable for integration into both simulation and implementation environments. Simulations at various levels of abstraction are shown to be relevant at different stages of protocol design. Environments based on the Cinderella SDL simulator and the ns-2 network simulator have been developed which allow early functional verification, along with detailed and accurate performance analysis of protocols under development. A hardware platform is presented which allows implementation of protocols with flexibility in the hardware/software trade-off. Measurement facilities are integral to the hardware framework, and provide a means for accurate real-world feedback on protocol performance.

This thesis examines the sources for generating financial and social capital for ethnic small business owners, particularly for Sri Lankan ethnic small businesses in Australia. The results further our understanding of raising capital by introducing a model by generating capital for ethnic small businesses. This model identifies the informal and formal sources of financial capital, factors influencing those sources and networking activities for generating social capital. We found that competition and rising costs are the major business problem for Sri Lankan ethnic small business owners, not raising capital. The reasons for using personal savings as the major surce of capital include difficulties associated with approaching financial institutions and government agencies. The role of networking with ethnic associations was also explored. Finally, recommendations are made to business owners on how to overcome various business problems and to promote better networking activities through ethnic associations. Recommendations are also made to government agency officials to provide information about government progammes, and to financial institutions about satisfying banking needs of ethnic small business owners. / Doctor of Philosophy (PhD)

Il est évident aujourd'hui que le trafic Internet est bien plus complexe et irrégulier qu'escompté, ce qui nuit grandement à un fonctionnement efficace des réseaux, ainsi qu'à la garantie de niveaux de performances et de qualité de service (QdS) satisfaisants. En particulier, le comportement du réseau est surtout mis à mal lorsque le trafic contient des anomalies importantes. Différentes raisons peuvent être à la source de ces anomalies, comme les attaques de déni de service (DoS), les foules subites ou les opérations de maintenance ou de gestion des réseaux. De fait, la détection des anomalies dans les réseaux et leurs trafics est devenue un des sujets de recherche les plus chauds du moment. L'objectif de cette thèse a donc été de développer de nouvelles méthodes originales pour détecter, classifier et identifier les anomalies du trafic. La méthode proposée repose notamment sur la recherche de déviations significatives dans les statistiques du trafic par rapport à un trafic normal. La thèse a ainsi conduit à la conception et au développement de l'algorithme NADA : Network Anomaly Detection Algorithm. L'originalité de NADA - et qui garantit son efficacité - repose sur l'analyse du trafic selon 3 axes conjointement : une analyse multi-critères (octets, paquets, flux, ...), multi-échelles et selon plusieurs niveaux d'agrégations. A la suite, la classification repose sur la définition de signatures pour les anomalies de trafic. L'utilisation des 3 axes d'analyse permettent de détecter les anomalies indépendamment des paramètres de trafic affectés (analyse multi-critères), leurs durées (analyse multi-échelles), et leurs intensités (analyse multi-niveaux d'agrégation). Les mécanismes de détection et de classification d'anomalies proposés dans cette thèse peuvent ainsi être utilisés dans différents domaines de l'ingénierie et des opérations réseaux comme la sécurité des réseaux, l'ingénierie du trafic ou des réseaux superposés, pour citer quelques exemples. Une contribu tion importante de la thèse a trait à la méthode de validation et d'évaluation utilisée pour NADA. NADA a ainsi été validé sur une base de trace de trafic contenant des anomalies documentées, puis évalué sur les principales traces de trafic disponibles. Les résultats obtenus sont de très bonne facture, notamment lorsqu'ils sont comparés avec ceux obtenus par d'autres outils de détection d'anomalies. De plus, la qualité des résultats est indépendante du type de trafic analysé et du type d'anomalie. Il a été en particulier montré que NADA était capable de détecter et classifier efficacement les anomalies de faible intensité, qui sont apparues comme des composantes essentielles des attaques DOS. NADA apporte donc une contribution intéressante en matière de sécurité réseau.
