Desde el 23 de febrero de 2004 la ETS Ingenieros Informáticos posee un perfil en dos redes sociales: Twitter y Facebook. Desde un primer momento el departamento de Unidad de Imagen y Comunicación, encargado de dichos perfiles, ha tenido claro que este era solo el primer paso para aprovechar al máximo las ventajas de las redes sociales en un contexto educativo universitario. En este trabajo se quiere dar forma a esa aspiración desarrollando una expansión del uso de las redes sociales. En este trabajo se analizan los seis primeros meses de trabajo con el perfil de Twitter y la página de Facebook con el objetivo de averiguar qué ha funcionado y qué ha fallado en la estrategia inicial prevista. Primero, se plantea un acercamiento desde el punto de vista estadístico con los datos que arrojan diferentes herramientas de análisis social y después, desde el punto de vista personal con las respuestas de la propia comunidad de la Escuela a una encuesta de satisfacción con los nuevos canales de comunicación. Además, de cara a la creación de nuevos perfiles se analiza el trabajo que realizan en ellas otras universidades y escuelas de informáticas. Con todos los datos sobre el trabajo previo se construyen una serie de buenas prácticas para instituciones universitarias en redes sociales que servirán para desarrollar los planes editoriales de dos nuevos perfiles: un canal de YouTube y una página de LinkedIn. Para terminar, se deja constancia de todo el proceso realizado en una metodología propia que servirá para poder seguir aumentando la red social de la escuela en el futuro con un enfoque en el alumno y que se fundamentará en el análisis y la mejora constante. Se espera que esta metodología pueda servir de modelo para la creación de perfiles sociales en otras universidades o para mejorar las ya existentes.---aBSTRACT---Since February 23rd of 2014, ETS Ingenieros Informáticos had a profile in two of the most popular social networks: Twitter and Facebook. From the beginning, the Communication Department in charge of these profiles knew that this was only a starting point to take advantage of all the advantages that social networks can bring to a higher education context. Thus, this paper aims at developing an expansion of the use of social networks. The present paper analyses the first sixth months of the use of the Twitter profile and the Facebook page to determine the aspects of the initial strategy that worked successfully and those that needed improvement. Firstly, I present a statistical approach the data from a statistical point of view taking into account all the information provided by the different social analysis tools. Then, I complement this first approach with a more personal point of view including the answers of the university community to a satisfaction survey regarding the new communication channels. Finally, in order to create new profiles, other universities’ work is reviewed and examined in depth. Taking into account the previous work, a series of good practices for university institutions is developed in order to be used as the basis of the new social plan to include two new social networks: a YouTube channel and a LinkedIn page. Finally, the whole process is described in a methodology that could be used to increase the School’s social network in the future. This procedure is student-centred and based on the constant analysis and improvement of the results. It is hoped that this methodology could be used as an example of a social network profile creation or improvement for other universities’ strategy.

Characterising users through demographic attributes is a necessary step before conducting opinion surveys from information published by such users in social media. In this paper, we describe, compare and evaluate different techniques for the identification of the attributes "gender"' and "place of residence" by mining the metadata associated to the users, the content published and shared by themselves, and their friendship networks. The results obtained show that the social network is a valuable source of information for obtaining the sociodemographic attributes of single users.

El presente PFC tiene como objetivo el desarrollo de un gestor domótico basado en el dictado de voz de la red social WhatsApp. Dicho gestor no solo sustituirá el concepto dañino de que la integración de la domótica hoy en día es cara e inservible sino que acercará a aquellas personas con una discapacidad a tener una mejora en la calidad de vida. Estas personas, con un simple comando de voz a su aplicación WhatsApp de su terminal móvil, podrán activar o desactivar todos los elementos domóticos que su vivienda tenga instalados, “activar lámpara”, “encender Horno”, “abrir Puerta”… Todo a un muy bajo precio y utilizando tecnologías OpenSource El objetivo principal de este PFC es ayudar a la gente con una discapacidad a tener mejor calidad de vida, haciéndose independiente en las labores del hogar, ya que será el hogar quien haga las labores. La accesibilidad de este servicio, es por tanto, la mayor de las metas. Para conseguir accesibilidad para todas las personas, se necesita un servicio barato y de fácil aprendizaje. Se elige la red social WhatsApp como interprete, ya que no necesita de formación al ser una aplicación usada mayoritariamente en España y por la capacidad del dictado de voz, y se eligen las tecnologías OpenSource por ser la gran mayoría de ellas gratuitas o de pago solo el hardware. La utilización de la Red social WhatsApp se justifica por sí sola, en septiembre de 2015 se registraron 900 millones de usuarios. Este dato es fruto, también, de la reciente adquisición por parte de Facebook y hace que cumpla el primer requisito de accesibilidad para el servicio domotico que se presenta. Desde hace casi 5 años existe una API liberada de WhatsApp, que la comunidad OpenSource ha utilizado, para crear sus propios clientes o aplicaciones de envío de mensajes, usando la infraestructura de la red social. La empresa no lo aprueba abiertamente, pero la liberación de la API fue legal y su uso también lo es. Por otra parte la empresa se reserva el derecho de bloquear cuentas por el uso fraudulento de su infraestructura. Las tecnologías OpenSource utilizadas han sido, distribuciones Linux (Raspbian) y lenguajes de programación PHP, Python y BASHSCRIPT, todo cubierto por la comunidad, ofreciendo soporte y escalabilidad. Es por ello que se utiliza, como matriz y gestor domotico central, una RaspberryPI. Los servicios que el gestor ofrece en su primera versión incluyen el control domotico de la iluminación eléctrica general o personal, el control de todo tipo de electrodomésticos, el control de accesos para la puerta principal de entrada y el control de medios audiovisuales. ABSTRACT. This final thesis aims to develop a domotic manager based on the speech recognition capacity implemented in the social network, WhatsApp. This Manager not only banish the wrong idea about how expensive and useless is a domotic installation, this manager will give an opportunity to handicapped people to improve their quality of life. These people, with a simple voice command to their own WhatsApp, could enable or disable all the domotics devices installed in their living places. “On Lamp”, “ON Oven”, “Open Door”… This service reduce considerably the budgets because the use of OpenSource Technologies. The main achievement of this thesis is help handicapped people improving their quality of life, making independent from the housework. The house will do the work. The accessibility is, by the way, the goal to achieve. To get accessibility to a width range, we need a cheap, easy to learn and easy to use service. The social Network WhatsApp is one part of the answer, this app does not need explanation because is used all over the world, moreover, integrates the speech recognition capacity. The OpenSource technologies is the other part of the answer due to the low costs or, even, the free costs of their implementations. The use of the social network WhatsApp is explained by itself. In September 2015 were registered around 900 million users, of course, the recent acquisition by Facebook has helped in this astronomic number and match the first law of this service about the accessibility. Since five years exists, in the internet, a free WhatsApp API. The OpenSource community has used this API to develop their own messaging apps or desktop-clients, using the WhatsApp infrastructure. The company does not approve officially, however le API freedom is legal and the use of the API is legal too. On the other hand, the company can block accounts who makes a fraudulent use of his infrastructure. OpenSource technologies used in this thesis are: Linux distributions (Raspbian) and programming languages PHP, Python and BASHCSRIPT, all of these technologies are covered by the community offering support and scalability. Due to that, it is used a RaspberryPI as the Central Domotic Manager. The domotic services that currently this manager achieve are: Domotic lighting control, electronic devices control, access control to the main door and Media Control.

The appearance of large geolocated communication datasets has recently increased our understanding of how social networks relate to their physical space. However, many recurrently reported properties, such as the spatial clustering of network communities, have not yet been systematically tested at different scales. In this work we analyze the social network structure of over 25 million phone users from three countries at three different scales: country, provinces and cities. We consistently find that this last urban scenario presents significant differences to common knowledge about social networks. First, the emergence of a giant component in the network seems to be controlled by whether or not the network spans over the entire urban border, almost independently of the population or geographic extension of the city. Second, urban communities are much less geographically clustered than expected. These two findings shed new light on the widely-studied searchability in self-organized networks. By exhaustive simulation of decentralized search strategies we conclude that urban networks are searchable not through geographical proximity as their country-wide counterparts, but through an homophily-driven community structure.

O desemprego tem sido objeto de preocupação no contexto político, econômico e social, uma vez que a população de trabalhadores desempregados enfrenta dificuldades diárias para a obtenção de trabalho/ou emprego, situação que gera intenso sofrimento psíquico e pode repercutir de modo negativo na saúde do trabalhador. Este estudo teve por objetivo investigar a percepção de suporte social e o consumo de álcool em desempregados. Por meio de estudo epidemiológico, quantitativo e transversal constituímos uma amostra de 300 indivíduos, recrutados em uma agência pública em São Bernardo do Campo SP, que capta vagas no mercado e encaminha trabalhadores para recolocação profissional. A amostra resultou em 54,3% pessoas do gênero masculino, com idade média de 29,30, com mínimo de 18 anos e máximo de 56 anos; 67% tinham ensino médio, sendo 50% solteiros, 52% encontravam-se desempregados de um a seis meses, 37% residiam em imóvel próprio, e 37% possuíam renda familiar de um a dois salários mínimos. Foram utilizados três instrumentos auto-aplicáveis para coleta dos dados: a) Questionário de características sócio-demográficas; b) Escala de Percepção de Suporte Social (EPSS); c) Teste para Identificação de Problemas Relacionados ao Uso de Álcool (AUDIT). Os dados coletados foram submetidos ao programa estatístico SPSS, versão 15.0 para Windows que permitiu fazer as correlações entre as variáveis. Os resultados indicaram correlações significativas entre as variáveis: suporte prático e renda; suporte prático e suporte emocional, com idade. Estas correlações sugeriram que os sujeitos apresentavam melhor percepção de suporte prático na medida em que aumentava a renda familiar, e que quanto maior a idade, menor é a percepção do suporte prático e emocional recebido pela rede social. O AUDIT não apontou correlações significativas entre as variáveis estudadas, e 76% da amostra se situou na zona 1 consumo de baixo risco ou abstinência. Não verificamos correlação entre consumo de álcool e desemprego.(AU)

The focus of this paper is the assessment of groups of agents or units in a network organization. Given a social network, the relations between agents are modeled by means of a graph, and its functionality will be codified by means of a cooperative game. Building on previous work of Gomez et al. (2003) for the individual case, we propose a Myerson group value to evaluate the ability of each group of agents inside the social network to achieve the organization's goals. We analyze this centrality measure, and in particular we offer several decompositions that facilitate obtaining a precise interpretation of it.

O objetivo geral deste estudo foi analisar a relação entre a rede e apoio social, satisfação com o apoio social recebido e as variáveis sociodemográficas, de saúde física e mental, dos idosos atendidos em um Ambulatório de Geriatria de um Hospital Geral Terciário do interior paulista. Trata-se de um estudo descritivo, transversal e exploratório, realizado com 98 idosos atendidos no referido ambulatório. Para a coleta de dados, utilizaram-se o Mini Exame do Estado Mental, um questionário de caracterização sociodemográfica e de saúde, a Escala de Depressão Geriátrica (EDG-15), o Índice de Katz, a Escala de Lawton e Brody, a Escala de medida da rede e apoio social do Medical Outcomes Study e a Escala de Satisfação com o Suporte Social. Os aspectos éticos foram respeitados conforme a Resolução 466/2012 do Conselho Nacional de Saúde. A média de idade dos idosos foi de 80,1 anos, 70,4% eram mulheres, 49,0% viúvos; a média de anos de estudo foi 2,3; 24,5% dos idosos residiam com o cônjuge e filhos ou somente com os filhos; a renda familiar média foi de R$1.773,70. Quanto à capacidade funcional, 80,6% eram independentes para as atividades básicas da vida diária e 88,8% eram parcialmente dependentes para as instrumentais. Os idosos possuíam, em média, 5,3 diagnósticos médicos e os sintomas depressivos estiveram presentes para 61,2% deles. Quanto à rede social, o escore total médio foi de 6,4 pessoas para contato na rede, sendo que 36,7% apresentavam médio contato e participação em atividades sociais. Em relação ao apoio social, o maior escore médio foi para a dimensão material (90,2) e o menor para a interação social positiva (81,8); já para a satisfação com o suporte social, 36,7% e 32,7% apresentaram alta e média satisfação, respectivamente. Foi encontrada correlação inversa entre os escores de todas as dimensões da escala de apoio social e os escores da EDG-15, indicando que quanto maior o apoio social em todas as dimensões, menor é a presença de sintomas depressivos e houve diferenças estatisticamente significativas para todas as dimensões, material (p=0,014), afetiva (p=0,026), interação (p=0,011), emocional (p=0,001) e informação (p=0,005); já a correlação entre os escores das dimensões da escala de apoio social e os escores na escala de Lawton e Brody, foi inversa e fraca para as dimensões material (r=-0,157) e informação (r=-0,027), sugerindo que quanto menor a independência para as AIVDs, maior o apoio social nas referidas dimensões, porém, não houve diferença estatisticamente significativa, material (p=0,121) e informação (p=0,789). A correlação entre os escores da EDG-15 e os escores da escala de satisfação com o apoio social, foi inversa e moderada (r=- 0,467), indicando que quanto maior a satisfação com o apoio social, menor a presença de sintomas depressivos, sendo estatisticamente significativa (p=0,000). Evidencia-se a importância de conhecer se os idosos estão inseridos em rede social e se percebem o apoio social para um melhor direcionamento da assistência prestada ao idoso e para o planejamento e formulação de políticas públicas, programas e projetos voltados a essa população

In this digital age organizations must focus on connecting with candidates and aspire for innovation in recruiting practices to remain competitive. This author investigated social networking to determine whether or not it provides reliable candidate information when recruiting for hire. Online media such as LinkedIn, Facebook, Twitter and MySpace, have become an integrated part of social and professional lives. Analysis of social networking revealed use for recruiting but posed challenges and advantages for organizations. A quantitative cross-sectional survey of social network members (N=136) indicated discrepancy in generational use of social networks and concerns regarding the validity and reliability of candidate information. Social networking promotes innovation in recruiting, however, by itself might not endorse equitability, validity and reliability.
Audiencia tradicional frente a audiencia social: un análisis comparativo en el prime-time televisivo
Resumo:
La interacción de redes sociales y productos televisivos ha dado pie al nacimiento de la televisión social en la que el espectador participa activamente en el desarrollo de los espacios. Este fenómeno emergente está siendo objeto de múltiples investigaciones en el campo de las audiencias por las posibilidades y el potencial que supone para el medio a la hora de conocer e interactuar con los espectadores. El objetivo de este trabajo es realizar una comparación entre la audiencia real y la audiencia social (o impacto social) de los programas emitidos en prime-time durante varias semanas de los meses de abril y mayo de 2013. Esta investigación se centra en Twitter por ser la red social que concentra gran parte de los debates sobre televisión (Gallego, 2013). Para ello se plantean las siguientes hipótesis de partida: 1- No existe paralelismo entre los cinco programas más vistos en televisión con aquellos que se sitúan entre los cinco con mayor audiencia social del mismo día. 2- El éxito de un programa en audiencia social no depende exclusivamente de su formato. Para alcanzar los objetivos de la investigación se estudian los datos de audiencia real procedentes de Kantar Media, así como los de impacto social facilitados Tuitele y Global-In-Media.

This presentation is about the inside story of the PhD project El malagueño real, mental y virtual. Configuración de los significados sociales de una variedad urbana in Hispanic Linguistics. That is, the production and perception of the Spanish spoken in the city of Malaga and used on the social network sites Facebook and Tuenti by users from Malaga is analysed. Actually, the southern Spanish variety in question is quite distinct from the national standard in terms of its phonetic features, its prestige, and the attitudes to it. Thus, the project started with the initial interest in «Why do people often communicate in very “strange” ways on social media» which then slightly changed to the final research interest in «What do the different non-standard variants mean in virtual (and real) malagueño?». This long – sometimes hazardous, yet mostly fun – process is exposed in more detail by looking at the research questions, the methods and results. Lastly, the presentation concludes with some lessons learnt and an outlook on possibilities and necessities for further investigation.

Social isolation is a predictor of morbidity and mortality in older people. Speech pathologists often consider that communication disabilities associated with normal ageing (sensory loss, language and discourse changes) contribute to social isolation. The aims of this study were to describe the functioning of older people using the International Classification of Functioning, Disability and Health (WHO, 2001) as a conceptual framework for language and sensory functioning, communicative activity, and social participation, and to explore the relationship between communication (both at an impairment level and an activity level), social participation and personal factors (demographics and emotional health). In a prospective study, 47 women and 28 men aged 62 to 98 years (mean=74 yrs) completed objective and subjective assessments of functioning and participation, and provided personal information. Assessments were individually conducted in a face- to-face interview situation with the primary researcher, who was a speech pathologist. Assessments revealed the sample had predominantly mild hearing and vision impairments, unimpaired naming ability, frequent involvement in a wide range of communication activities, and variable social network size and social activities participation. Social participation was shown to be associated with vision, communication activities, age, education and emotional health. Naming and hearing impairments were not reliable predictors of social participation. It was concluded that professionals interested in maintaining and improving social participation of older people could well consider these predictors in community-directed interventions. Speech pathologists should therefore promote older people's involvement in everyday communicative activities while also limiting the impact of communication-related impairments, so that social participation is maintained in our ageing population.

Network building and exchange of information by people within networks is crucial to the innovation process. Contrary to older models, in social networks the flow of information is noncontinuous and nonlinear. There are critical barriers to information flow that operate in a problematic manner. New models and new analytic tools are needed for these systems. This paper introduces the concept of virtual circuits and draws on recent concepts of network modelling and design to introduce a probabilistic switch theory that can be described using matrices. It can be used to model multistep information flow between people within organisational networks, to provide formal definitions of efficient and balanced networks and to describe distortion of information as it passes along human communication channels. The concept of multi-dimensional information space arises naturally from the use of matrices. The theory and the use of serial diagonal matrices have applications to organisational design and to the modelling of other systems. It is hypothesised that opinion leaders or creative individuals are more likely to emerge at information-rich nodes in networks. A mathematical definition of such nodes is developed and it does not invariably correspond with centrality as defined by early work on networks.

It is technically feasible for mobile social software such as pairing or ‘matchmaking’ systems to introduce people to others and assist information exchange. However, little is known about the social structure of many mobile communities or why they would want such pairing systems. While engaged in other work determining requirements for a mobile travel assistant we saw a potentially useful application for a pairing system to facilitate the exchange of travel information between backpackers. To explore this area, we designed two studies involving usage of a low-fidelity role prototype of a social pairing system for backpackers. Backpackers rated the utility of different pairing types, and provided feedback on the social implications of being paired based on travel histories. Practical usage of the social network pairing activity and the implications of broader societal usage are discussed.

Background: Developing the knowledge base on the impact of aphasia on people's social lives has become increasingly important in recent times to further our understanding of the broad consequences of communication disability and thus provide appropriate services. Past research clearly indicates that relationships and social activities with family members and others undergo change with the onset of aphasia in an individual, however more evidence of a quantitative nature would be beneficial. Aims: The current research furthers our knowledge by quantifying chronically aphasic older people's regular social contacts and social activities, and places them in context by comparing them with healthy older people of similar age and education. Methods & Procedures: A total of 30 aphasic participants aged 57 to 88 years, and 71 non-aphasic controls aged 62 to 98 years were interviewed by a speech and language therapist using self-report measures of Social Network Analysis (Antonucci & Akiyama, 1987) and Social Activities Checklist (Cruice, 2001, in Worrall & Hickson, 2003). Demographic information was also collected. Descriptive statistics are presented and independent samples t tests were used to examine differences between the groups. Outcomes & Results: Participants with primarily mild to moderate aphasic impairment reported a considerable range of social contacts (5-51) and social activities (8-18). Many significant differences were evident between the two groups' social contacts and activities. On average, aphasic participants had nine fewer social contacts (mainly friend'' relationships) and three fewer social activities (mainly leisure'' activities) than their non-aphasic peers. The majority of controls were satisfied with their social activities, whereas the majority of aphasic participants were not and wanted to be doing more. There were some general similarities between the groups, in terms of range of social contacts, overall pattern of social relationships, and core social activities. Conclusions: Older people with chronic aphasia had significantly fewer social contacts and social activities than their peers. People with aphasia expressed a desire to increase the social activity of their lives. Given the importance of leisure activity and relationships with friends as well as family for positive well-being, speech and language therapists may direct their rehabilitation efforts towards two areas: (1) conversational partner programmes training friends to maintain these relationships; and (2) encouraging and supporting aphasic clients in leisure activities of their choice.
