A study of data analysis techniques. Application to personal data analysis in the context of social networks

En los últimos años la sociedad está experimentando una serie de cambios. Uno de estos cambios es la datificación (“datafication” en inglés). Este término puede ser definido como la transformación sistemática de aspectos de la vida cotidiana de las personas en datos procesados por ordenadores. Cada día, a cada minuto y a cada segundo, cada vez que alguien emplea un dispositivo digital,hay datos siendo guardados en algún lugar. Se puede tratar del contenido de un correo electrónico pero también puede ser el número de pasos que esa persona ha caminado o su historial médico. El simple almacenamiento de datos no proporciona un valor añadido por si solo. Para extraer conocimiento de los datos, y por tanto darles un valor, se requiere del análisis de datos. La ciencia de los datos junto con el análisis de datos se está volviendo cada vez más popular. Hoy en día, se pueden encontrar millones de web APIs estadísticas; estas APIs ofrecen la posibilidad de analizar tendencias o sentimientos presentes en las redes sociales o en internet en general. Una de las redes sociales más populares, Twitter, es pública. Cada mensaje, o tweet, publicado puede ser visto por cualquier persona en el mundo, siempre y cuando posea una conexión a internet. Esto hace de Twitter un medio interesante a la hora de analizar hábitos sociales o perfiles de consumo. Es en este contexto en que se engloba este proyecto. Este trabajo, combinando el análisis estadístico de datos y el análisis de contenido, trata de extraer conocimiento de tweets públicos de Twitter. En particular tratará de establecer si el género es un factor influyente en las relaciones entre usuarios de Twitter. Para ello, se analizará una base de datos que contiene casi 2.000 tweets. En primer lugar se determinará el género de los usuarios mediante web APIs. En segundo lugar se empleará el contraste de hipótesis para saber si el género influye en los usuarios a la hora de relacionarse con otros usuarios. Finalmente se construirá un modelo estadístico para predecir el comportamiento de los usuarios de Twitter en relación a su género.

Effects of inspections in small world social networks with different contagion rules

Inspections are used to prevent tax evasion or any other unlawful behavior. ? The effect of inspections depends on the network topology and the contagion rule. ? The network is modeled as a Watts?Strogatz Small World that is tuned from regular to random. ? Two contagion rules are applied: continuous and discontinuous. ? The equilibrium populations of payers and evaders are obtained in terms of these system parameters.

The anatomy of urban social networks and its implications in the searchability problem

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.

A Quantitative Exploration of Social Networks: Verifying the Legitimacy and Equitability of Social Networks in Recruiting

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.

Social networks in cultural industries

Although cultural industries can benefit from social networks in many ways, few Spanish studies examine the extent to which firms within this economic sector actually use such networks. This study's objective is to investigate the role of online social networks in Spanish cultural firms. The study begins with a literature review on cultural industries and social networks. Then the study proceeds to a Delphi analysis that draws upon experts' opinions. Results reveal a predominance of utilitarian uses over expressive ones, as well as an overriding use of proactive motivations rather than reactive ones within the context of cultural firms' use of social networks. The study confirms the profitability of these networks and the transfer of influence or power from providers to the consumers of cultural goods and services.

Management of social networks in the educational process

The research developed in this work consists in proposing a set of techniques for management of social networks and their integration into the educational process. The proposals made are based on assumptions that have been proven with simple examples in a real scenario of university teaching. The results show that social networks have more capacity to spread information than educational web platforms. Moreover, educational social networks are developed in a context of freedom of expression intrinsically linked to Internet freedom. In that context, users can write opinions or comments which are not liked by the staff of schools. However, this feature can be exploited to enrich the educational process and improve the quality of their achievement. The network has covered needs and created new ones. So, the figure of the Community Manager is proposed as agent in educational context for monitoring network and aims to channel the opinions and to provide a rapid response to an academic problem.

Bundeswehr 3.0: The political, military and social dimensions of the reform of the German armed forces. OSW Point of View Number 28, May 2012

This reform of the Bundeswehr, launched in 2011, is the latest of the three decisive stages in the post-war transformation of the German armed forces. The reform aims at “constructing” the armed forces anew in the political, military and social dimensions.The present paper presents the evolution of the role of the armed forces in German foreign and security policy and the ongoing process of “constructing” a new Bundeswehr. It analyses the process of redefining the objectives and principles of: the Bundeswehr’s participation in international operations, its current military transformation, and changes in its image and social identity. It also presents the implications of this broader transformation for political and military.

Integrating Europeans: The Political Economy and Social Aspects of Europeanization. ACES Working Papers (Curriculum Development), 2012

This course, then, investigates the effects of integration on European citizens as well as the duality of the EU as a competitive and social model. It is sensitive to the involvement of social groups, protest, and domestic politics in the study of market integration. Some of the questions we explore are: What are the effects of regulatory policy-making on social actors, how do such actors’ strategies and behaviors change as a consequence, and how to they overcome their collective action problems? Why is it that the logic of integration has at times followed a logic of “permissive consensus” while at other times it has been described as a “constraining dissensus”? What is the importance of discourse in domestic politics in order to articulate and legitimate Europeanization? How do European identities change as a consequence of policymaking as well as of protest? To what extent do ordinary Europeans matter in terms of accepting and opposing the project of European integration, how do European citizens in core and peripheral EU states experience Europeanization, and how is their involvement in the integration project to be conceptualized?

The Israeli lobby for Research and Innovation in the European Union. An example of efficient cooperation in the European Neighbourhood? Bruges Political Research Papers 49/2015.

Israel figures among the world-leaders in R&D expenditure and has a high-performing scientific community. Since the 1990s it has been associated with the Scientific Policy of the European Union via the European Research Framework Programmes (FP). The cooperation between Israel and the EU in this domain has gradually increased and benefits the scientific communities on both sides. In 2014 the association of Israel to the latest and biggest European FP ever adopted (Horizon 2020) was renewed for the fourth time. Based on all the scientific evidence provided, the elaboration of a European Research Policy can be identified as a highly regulated domain, offering relevant ‘channels of influence’. These channels offer Israel the opportunity to act within the Research Policy system. Being a member of several formal EU bodies in charge of implementing EU Research Policy, Israel is able to introduce its positions effectively. This is accompanied by an outstanding level of activity by Israel in linking concrete EU Research Policy measures to the Israeli Scientific Community at the national level. To carry out this task, Israel relies on an effective organization, which remodels the provided EU structures: European ‘National Contact Points’ (NCPs) are concentrated within the ‘Europe Israel R&D Directorate’ (ISERD). ISERD connects efficiently all the relevant actors, forums and phases of EU-Israeli Research Policy. ISERD can be recognized as being at the heart of Israel's research cooperation with the EU, and its structure may be a source of in

A probabilistic switch model of information flow in social networks: Application for virtual circuits to organizational design

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.
