During the second half of the 20th century, there was an epic deterioration of the urban fabric of the typical American neighborhood. Starting with the fleeing of city dwellers into the outskirts of suburbia in the 1950s and the exodus of commercial institutions in the 1970s, neighborhood sprawl hit its stride with the elimination of the neighborhood school in the 1980s. With this community-defining component being replaced by giant, remote educational facilities, the American neighborhood was finally a shell of its former self. If the neighborhood represents the cell, then the home represents the nucleus. In 2003, 1.1 million children were being homeschooled in America, with signs of homeschooling becoming a growing trend. One of the main reasons parents chose to homeschool their children was concern about the environment of other schools. With a large number of students being sent to mega-schools and a growing number of students being homeschooled, there is an increasing gap between the scales of schools being used for education, and neither seems to be a complete solution. In addition, a significant part of relevant literacy in today?s global community deals with digital literacy. The digital divide is the gap between those people with effective access to digital and information technology, and those without. Many institutions including the United Nations believe the digital divide is the key to local and global, social and economic inequalities. Information, or knowledge, is being stored and made accessible through digital means. However, if a person does not know how to access this information, they are less equipped than the person who does, and the problem of a gap in knowledge becomes exponentially larger. In what ways can low population learning environments be networked into the urban fabric of a blighted neighborhood for the purpose of improving academic performance? In addition, what are the social, civic and economic opportunities and disadvantages afforded to a neighborhood when a digital learning network is overlaid with a physical network of learning environments? This thesis intends to reestablish the neighborhood school, by injecting contemporary, low-population learning environments branded as HOM-S to act as a brand of modular architecture which will bridge the gap between the home and the school. The solution is proposed as potentially ubiquitous, but for the sake of this thesis I will be using the neighborhoods surrounding Holmes Elementary School and Liberty City Elementary School in Miami, Fl, as its site. This neighborhood has a high crime rate, low testing scores, high dropout rate, lack of positive identity, and low economic class, and therefore represents the extreme conditions this thesis is poised to remediate. The program will be defined as a pre-university learning environment that is meant to complement and correct at-risk education systems and the neighborhoods they serve. The HOM-S will be a bridge between the home and the mega-school, creating both an ?education path? and a campus network for pre-university students. Through the use of flexible technology, distance learning networks, and site sensitive architecture, as well as a re-interpretation of curriculum and teacher-student roles, these environments will be designed to turn deteriorated neighborhoods into healthy communities.

Authors: Edina Hrustic & Maria Iverbo Title: Facebook – a virtual meetingplace and a gossipcave Level: BA Thesis in Journalism Location: Linnaeus University Language: Swedish Number of pages: 72 Abstract The aim of our study was to examine the meaning of the social media Facebook for young people who are in the age of 16 to 25 years. We wanted to gain an understanding in the youths´ thoughts and beliefs of how Facebook exists and plays a role in their lives. As a result from this research, we discussed how social media might affect the future of journalism. We formed our thesis based on research of the digital network society, social networks, the youth culture, and how the target group; the young people use and experience social media. We made a questionnaire for 36 high school students, and three of these participated in a focusgroup-discussion. We combined and analyzed the response from the questionnaire and the focus group in our final result, and discussed patterns and relations between the youngsters´ answers. Our result shows that Facebook mostly is regarded to be a virtual meetingplace, where these young people can interact and communicate with each other. They mostly communicate with their friends from the real-life, and youths´ use Facebook as a tool when they want to find out what people in their surrounding do. The questionnaire result also shows that Facebook can be seen as an information channel, where the young people can get gossip and offer each other invitations to common events. From this study, we can point out that the social network is practically of great importance in young peoples’ lives. The questionnaire of Facebook and how young people´s habits are affected implies that it is important to use the social network discussion while analysing the convergence between so called; "old" and "new media". Young people steer and direct the use of media, and that is the reason why the understanding about their thoughts of social media is significantly important. One could practically say that youngsters can affect the future of journalism, and the design and development of media. Key words: young people, Facebook, social media, virtual communication, the convergence of media, digital network society, journalism

This is the maximum of our century. With the digital network it has become stronger because we are even more entangled in a network of complex and changing networks, consisting of nodes (actants of all kinds) and edges (connections). However, the nodes are only part of a whole. Nodes connected are simply a static structure. Therefore, there is something that gives life to the network: the dynamics - the movements that the nodes perform, depending on the connections, revealing multiinteractions in digital networks. The multi-interactions are a type of communication action, hybrid and singular among actants that, by allowing mediation in the communication standard "all-all" without considerably reduce reciprocity between them, has reshaped the world in various dimensions, including the way to do global politics. The World We Want platform, created by the United Nations to join in an unprecedented way the opinion of civil society in building the new global agenda, called Sustainable Development Goals (SDGs), illustrates this process. After all, the platform shows that the UN has appropriated the cyberculture attributes to an experiment complex and impossible before the digital culture. Therefore, our goal is to accompany the phenomenon of multiinteractions in The World We Want platform to understand, from the Web macro dimension, how the UN faced the complexity permeated throughout this communication process and converted the conflict in a consensus, the SDGs Agenda. Therefore, for the methodological procedure, we use the systems of Information Architecture, the Heuristic Evaluation by Nielsen, Actor-Network Theory and its extension, the Cartography of Controversies. From the analysis, we conclude that the UN used the complexity of multiinteractions to achieve your goal, turning The World We Want in a hub of sustainability debates and stimulating the collective intelligence and collaborative processes in network. However, although the platform has changed the way of building global agendas and has described as a tool for promoting democracy, we understand that it has not yet reached that level. Therefore, the platform allowed the people to be heard, but not to participate in decisions by the summit, making the SDGs Agenda another document that only supports the UN consolidated discourse for almost four decades. / “Tudo está conectado”. Esta é a máxima do nosso século. E com a rede digital ela se tornou mais forte, pois estamos ainda mais emaranhados em uma rede de redes complexas e mutáveis, compostas por nós (actantes de todos os tipos) e arestas (conexões). Contudo, os nós sozinhos são apenas partes de um todo e os nós conectados não passam de uma estrutura estática. Logo, existe algo que dá vida à rede: as dinâmicas – os movimentos que os nós realizam em função das conexões, revelando, na rede digital, as multiinterações. As multi-interações são um tipo de ação comunicativa, híbrida e singular entre os actantes que, ao permitir a mediação no padrão de comunicação “todos-todos”, sem reduzir, consideravelmente, a reciprocidade entre eles, tem reconfigurado o mundo em várias dimensões, inclusive na forma de fazer política global. A plataforma The World We Want, criada pela ONU para aderir de forma inédita a opinião da sociedade civil na construção da nova agenda global, denominada Objetivos de Desenvolvimento Sustentável (ODS), ilustra tal processo. Afinal, a plataforma revela a ONU se apropriando dos atributos da cibercultura para realizar uma experiência complexa e impossível antes da cultura digital. Nosso objetivo se constitui, portanto, no acompanhamento do fenômeno das multi-interações na plataforma The World We Want para entender, a partir da dimensão macro da Web, como a ONU enfrentou a complexidade permeada em todo esse processo comunicacional e converteu os conflitos num consenso, a Agenda ODS. Para tanto, quanto procedimento metodológico, nos apropriamos dos Sistemas da Arquitetura da Informação, da Avaliação Heurística de Nielsen, da Teoria Ator-Rede e de sua extensão, a Cartografia de Controvérsias. E, a partir da análise, concluímos que a ONU usou a própria complexidade das multi-interações para atingir seu objetivo, transformando a The World We Want em um hub dos debates da sustentabilidade e estimulando a inteligência coletiva e os processos colaborativos em rede. No entanto, embora a plataforma tenha mudado a forma de construir agendas globais e seja descrita como um instrumento de promoção da democracia, entendemos que ela não atingiu esse nível ainda. Pois, ela permitiu que a população fosse ouvida, mas não que esta participasse das decisões junto à cúpula da ONU, tornando a Agenda ODS mais um documento que apenas sustenta o discurso consolidado da Organização há quase quatro décadas.

This research investigates the Twitter network sphere of the 112th U.S. House of Representatives and the 18th Korean National Assembly members. Drawing from social network analysis, this study explores and compares structural characteristics of each legislative political network at diverse network levels – legislative, party and personal network. Mapping these networks highlights the major features of these two elite political networks grounded in a new social medium. Findings indicate that U.S. and Korean lawmakers have created and are enjoying affluent and multi-layered digital networks. Dynamic legislative-body networks, strong party networks, and a variety of personal networks with diverse partisan and bipartisan relationships demonstrate how politicians are agile at using new mediums. This research confirmed that these newly created legislative networks go beyond partisanship. Complicated structures demonstrate active and mutual interactions among lawmakers, and the political networks with large numbers of bipartisan tie relationships indicate that the political elite communicate, interact, and build relationships with each other rather than remaining disconnected or isolated. This research revealed new types of leaders – digital opinion leaders – emerging from newly created digital legislative networks: the most connected lawmakers; lawmakers who have great potential to coordinate party politics; the most sought after leaders; and most sociable lawmakers. By examining lawmakers’ patterns of relationship building in the network, this research tests whether these relationships are dependent on party position, ruling or opposition, in the network. In turn, this provides evidence for different uses of this new medium by party position in both legislative bodies. Detailed examination of Twitter use by political elites in Korea and the U.S. illuminate how this new media platform is being adopted by and changing politics in two distinct social and cultural settings. This new political arena, a fully digitalized and networked sphere where dynamic competition and cooperation occurs between political elites, has emerged as one of the political battlefields in politics today. / text

Recent rapid advancements in mobile communication and emerging demands for complicated multimedia content and services over mobile systems have caused a dramatic increase in research interest in this area. Among the topics covering multimedia service performance over the wireless interface, the quality of received multimedia content is an important issue. With the increase of visual media in mobile services, user opinion acquired through perception of received image quality will play an increasingly important role in determining the effectiveness of such services. The work documented in this thesis is motivated by the general lack of published work on software test beds for Third Generation Mobile Network (3G) and in particular for investigating mobile environment multimedia quality degradation. A 3G multimedia quality analysis system is presented, subjecting the input multimedia stream to the simulated 3G radio activities and measuring its degradation in terms of human perception. This approach takes a new and different model of multimedia quality measurement in a wireless communication domain, showing the possibility of a more effective approach that can be applied in many cases for assisting service quality assurance research across this area. The development of this software system is covered in detail together with in-depth analysis of multimedia image quality over a simulated 3G radio interface. Universal Mobile Telecommunications System (UMTS) is the 3G standard chosen for study in this work. The suggested test bed simulates a single Frequency Division Duplex (FDD) downlink UMTS Territorial Radio Access (UTRA) channel, where the received media's image analysis is performed using a Human Vision System (HVS) based image quality metric. The system aims to provide a multipurpose and versatile multimedia 3G test bed for use in testing of various solutions for protecting multimedia data across a 3G radio interface. Furthermore, it produces effective human vision oriented feedback on visual media degradation, providing a new and efficient method to address effectiveness of solutions in multimedia delivery over a mobile environment. This thesis shows the ability of HVS-based image quality metric in analyzing degradation of visual media over a noisy mobile environment. This presents a novel direction in the area of telecommunication service multimedia quality analysis, with potential user quality perception being considered on top of data or signal-based error measurements. With such a new approach, development of multimedia protection solutions can be made more effective. Effective feedback provided by considering quality measurement with strong correlation to human perception allows close analysis of user visual discrimination across an image. An example of the usefulness of this information is especially visible if considering development of a content-based multimedia data protective system that provides different levels of protection, depending on the importance of visual media. An apparent potential application of this thesis is in the testing of a multimedia/image protection protocol in a downlink channel. Future work might aim to extend the current system by adding network level traffic simulations and further addition of dynamic network control components, further considering network traffic conditions.

Para tanto, foi utilizado um sistema de inferência nebulosa com um sistema de análise de confiabilidade de instrumentos a partir dos diagnósticos disponibilizados na rede industrial Fieldbus Foundation®. O resultado é uma simples, prática e ao mesmo tempo poderosa ferramenta que permite aos operadores analisarem e identificarem falhas e todas as suas causas prováveis, permitindo-lhes assim tomar ações preventivas e/ou corretivas mais rapidamente e com maior assertividade. Essa metodologia foi desenvolvida em VBA Excel® com interface amigável e gráfica. Para cada falha detectada é detalhada sua causa raiz (pode ser mais de uma), ação a ser tomada e é dada uma indicação percentual de intensidade de falha, facilitando a priorização das ações de manutenção / Abstract: The objective is to create a methodology for to monitor and to detect faults in real time, as for process as for instruments in a distillation column. For this, we used a fuzzy inference system with another instruments reliability analysis system from the diagnostics available in the Fieldbus Foundation® industrial network. The result is a simple, practical and yet powerful tool that allows the operators to analyze and to identify faults and their possible causes, thus allowing them to take preventive and / or corrective actions more quickly and with greater assertiveness. This methodology was developed in Excel® VBA with friendly interface and graphics. For each fault detected is detailed their root-cause (may be more than one is possible), the actions to take and so, it's given a percentage indication of failure intensity, facilitating the prioritization for maintenance's actions / Mestrado / Mecanica dos Sólidos e Projeto Mecanico / Mestre em Engenharia Mecânica

International Telemetering Conference Proceedings / October 25-28, 1993 / Riviera Hotel and Convention Center, Las Vegas, Nevada / As technology progresses we are faced with ever increasing volumes and rates of raw and processed telemetry data along with digitized high resolution video and the less demanding areas of video conferencing, voice communications and general LAN-based data communications. The distribution of all this data has traditionally been accomplished by solutions designed to each particular data type. With the advent of Asynchronous Transfer Modes or ATM, a single technology now exists for providing an integrated solution to distributing these diverse data types. This allows an integrated set of switches, transmission equipment and fiber optics to provide multi-session connection speeds of 622 Megabits per second. ATM allows for the integration of many of the most widely used and emerging low, medium and high speed communications standards. These include SONET, FDDI, Broadband ISDN, Cell Relay, DS-3, Token Ring and Ethernet LANs. However, ATM is also very well suited to handle unique data formats and speeds, as is often the case with telemetry data. Additionally, ATM is the only data communications technology in recent times to be embraced by both the computer and telecommunications industries. Thus, ATM is a single solution for connectivity within a test center, across a test range, or between ranges. ATM can be implemented in an evolutionary manner as the needs develop. This means the rate of capital investment can be gradual and older technologies can be replaced slowly as they become the communications bottlenecks. However, success of this evolution requires some planning now. This paper provides an overview of ATM, its application to test ranges and telemetry distribution. A road map is laid out which can guide the evolutionary changeover from today's technologies to a full ATM communications infrastructure. Special applications such as the support of high performance multimedia workstations are presented.
