La promozione musicale sui social network

L’industria musicale non ha mai vissuto un periodo di cambiamento così intenso e profondo come al giorno d’oggi. La sua digitalizzazione attraverso lo streaming musicale, la nascita di nuovi dispositivi che ne consentano la fruizione e l’interazione tra industria discografica e un pubblico sempre più centrale e determinante nelle scelte produttive e distributive del mercato, sono solo alcuni degli aspetti, indubbiamente i più importanti, che caratterizzano questa nuova fase della storia della musica. Attraverso questa tesi di laurea ho cercato di osservare e approfondire come in questi ultimi anni l’industria musicale si stia approcciando al mondo dei social network per promuovere e distribuire i prodotti musicali. Viene tracciato un quadro generale dell’ambiente dei social media, mostrandone sia i lati tecnologici che sociali, fino ad evidenziarne aspetti positivi e negativi. Nella seconda parte della trattazione invece, vengono osservate le strategie comunicative adottate dagli artisti e dagli addetti ai lavori per arrivare più efficacemente al pubblico e il ruolo che rivestono i vecchi media e l’utenza nel diffondere su larga scala il prodotto musicale.

Automated organizational network analysis for enterprise 2.0

Social Networking Sites have recently become a mainstream communications technology for many people around the world. Major IT vendors are releasing social software designed for use in a business/commercial context. These Enterprise 2.0 technologies have impressive collaboration and information sharing functionality, but so far they do not have any organizational network analysis (ONA) features that reveal any patterns of connectivity within business units. This paper shows the impact of organizational network analysis techniques and social networks on organizational performance, we also give an overview on current enterprise social software, and most importantly, we highlight how Enterprise 2.0 can help automate an organizational network analysis.

How enterprise 2,0 firms take advantage of emergent social software platforms to manage knowledge

This research aims to provide a better understanding on how firms stimulate knowledge sharing through the utilization of collaboration tools, in particular Emergent Social Software Platforms (ESSPs). It focuses on the distinctive applications of ESSPs and on the initiatives contributing to maximize its advantages. In the first part of the research, I have itemized all types of existing collaboration tools and classify them in different categories according to their capabilities, objectives and according to their faculty for promoting knowledge sharing. In the second part, and based on an exploratory case study at Cisco Systems, I have identified the main applications of an existing enterprise social software platform named Webex Social. By combining a qualitative and quantitative approach, as well as combining data collected from survey’s results and from the analysis of the company’s documents, I am expecting to maximize the outcome of this investigation and reduce the risk of bias. Although effects cannot be universalized based on one single case study, some utilization patterns have been underlined from the data collected and potential trends in managing knowledge have been observed. The results of the research have also enabled identifying most of the constraints experienced by the users of the firm’s social software platform. Utterly, this research should provide a primary framework for firms planning to create or implement a social software platform and for firms willing to increase adoption levels and to promote the overall participation of users. It highlights the common traps that should be avoided by developers when designing a social software platform and the capabilities that it should inherently carry to support an effective knowledge management strategy.

Social-business tensions and their management in social enterprise: evidence from Finland.

This thesis aims to provide insight into the social-business tensions the social enterprises face in their operation and how they manage them. The social-business tensions are examined from four theoretical perspectives using triangulation approach. The theoretical lenses chosen are organizational identity, stakeholder theory, paradox theory and institutional theory. The theories aim to clarify, how the tensions are formed, how they appear and how they are managed in social enterprises. One viewpoint of this thesis is to examine the competence of these theories in explaining the social-business tensions in practise. The qualitative data was collected by interviewing persons from the management of two social enterprises. The empirical evidence of this thesis suggests that the appearing of social-business tensions varies between the social enterprises and they can be seen both as an advantage and as a challenge. Most of the social-business tensions arise from the enterprise’s multiple incoherent objectives, their stakeholders’ various demands and the differing understanding of the company’s central operation among the members of the organization. According to this thesis, the theories of organizational identity, stakeholder, paradox and institution are all able to provide unique insight into the identification and management of the social-business tensions. However, the paradox theory turned out to be the most abstract of the theories and thus being the farthest from the practise.

El foco de interés lo constituyen las comunidades, principales gestores del proceso emprendedor, así como las oportunidades de crear a través de la empresa social, nuevas perspectivas de desarrollo social y abrir una línea de estudio que no existe en las Ciencias Sociales.

Interventions in social networks: impact on mood and network dynamics

Results from two studies on longitudinal friendship networks are presented, exploring the impact of a gratitude intervention on positive and negative affect dynamics in a social network. The gratitude intervention had been previously shown to increase positive affect and decrease negative affect in an individual but dynamic group effects have not been considered. In the first study the intervention was administered to the whole network. In the second study two social networks are considered and in each only a subset of individuals, initially low/high in negative affect respectively received the intervention as `agents of change'. Data was analyzed using stochastic actor based modelling techniques to identify resulting network changes, impact on positive and negative affect and potential contagion of mood within the group. The first study found a group level increase in positive and a decrease in negative affect. Homophily was detected with regard to positive and negative affect but no evidence of contagion was found. The network itself became more volatile along with a fall in rate of change of negative affect. Centrality measures indicated that the best broadcasters were the individuals with the least negative affect levels at the beginning of the study. In the second study, the positive and negative affect levels for the whole group depended on the initial levels of negative affect of the intervention recipients. There was evidence of positive affect contagion in the group where intervention recipients had low initial level of negative affect and contagion in negative affect for the group where recipients had initially high level of negative affect.

Investigation of the Network Construction Behaviour on Social Networking Sites

By enabling connections between individuals, Social Networking Sites, such as Facebook, promise to create significant individual as well as social value. Encouraging connections between users is also crucial for service providers who increasingly rely on social advertising and viral marketing campaigns as important sources of their revenue. Consequently, understanding user’s network construction behavior becomes critical. However, previous studies offer only few scattered insights into this research question. In order to fill this gap, we employ Grounded Theory methodology to derive a comprehensive model of network construction behavior on social networking sites. In the following step we assess two Structural Equation Models to gain refined insights into the motivation to send and accept friendship requests – two network expansion strategies. Based on our findings, we offer recommendations for social network providers.

Stigma, social relationship and HIV testing in the workplace : evidence from South Africa

This paper explores whether a worker's unwillingness to make his/her HIV-positive status or test-taking experience known by colleagues impedes his/her decision to test for HIV. After analyzing the new survey data provided by employees working for a large multinational enterprise in South Africa (2009-2010), this study finds that this unwillingness is negatively associated with test-taking (at the enterprise's on-site clinic) of workers who are extensively networked with close colleagues (i.e., know their phone numbers). It appears that the expected disutility associated with HIV/AIDS-related stigma prohibits test uptake. When introducing HIV counseling and testing programs into a corporate sector, providing all workers with an excuse to test in the workplace and/or inducing them to privately test outside the workplace may be effective in encouraging the uptake.

Estudio del Fenómeno Social Media en las grandes corporaciones del sector TIC

Este trabajo trata el estudio de la implementación y desarrollo de las diversas plataformas del social media: redes sociales y del conocimiento, blogs y herramientas colaborativas en el ámbito corporativo de la empresa. El estudio recopila información de consultoras tecnológicas, de artículos y de diversas plataformas social media y se realiza una investigación sobre el tema planteado. Se incluye el análisis de 42 encuestas a profesionales de dos grandes empresas de las telecomunicaciones en España. Estas dos empresas cuentan una con cerca de 28000 empleados y la otra con más 300 empleados en sus filiales españolas. Ambas tienen una importante presencia internacional. Estas dos empresa se diferencian de otras empresas del sector de las telecomunicaciones en que están apostando en la implementación del social media en sus procesos internos. Además se incluye el estudio y análisis de las estadísticas de uso y de una series de encuestas realizadas en el muro de la red social corporativa de una multinacional de las telecomunicaciones durante tres meses. Se presenta una nueva cultura social de empresa innovadora en áreas como la gestión del conocimiento, comunicación interna, formación e innovación. Y se ofrece una visión cuantitativa y de la implantación del social media en los procesos de una empresa. Se desarrolla una exposición donde se detalla el proceso de estudio de las diferentes plataformas social media y áreas de aplicación en la empresa, el estudio de los aspectos legales de su aplicación y uso y la implementación y desarrollo. Asimismo se expone un análisis teórico-práctico del cálculo del retorno de la inversión (ROI) y por último un análisis de la información recopilada en las encuestas y en el estudio estadístico de la red social corporativa. Los datos de las encuestas fueron analizados mediante estadística descriptiva basada en gráficos y tablas de contingencia donde se calculan residuos y porcentajes totales para analizar la dependencia entre el social media, eficiencia, productividad y cuenta de resultados, además del análisis de la aportación del social media a la misión, comunicación interna y gestión del conocimiento en la empresa. También se realizan cálculos de distribuciones Chi-cuadrado para demostrar la dependencia del social media-productividad y del GAP que relaciona la importancia y el nivel de satisfacción del social media. En el análisis teórico-práctico se toman como parámetros los beneficios, costes, flexibilidad y riesgo. Los beneficios van ligados a la productividad, gestión del conocimiento, capital humano y procesos internos. Los costes a las licencias de software, administración, implementación y formación. A partir de estos parámetros se realizó el estudio de un modelo de empresa que representa a una gran empresa de las TIC en España. Los datos para el estudio son estimativos dentro de la realidad, debido a que la intención no es saber estos valores reales sino el estudio teórico-práctico del método y su aplicación para el calculo del ROI. El estudio estadístico del la red social se realizo durante tres meses y se obtuvo el progreso de uso de la red social en eventos tales como: número de participantes activos, mensajes publicados, archivos subidos, grupos activos y tipos y plataformas de acceso. Del estudio de los datos estadísticos de estos eventos se obtuvieron indicadores de participación, actividad y conocimiento de la red social que son útiles par el calculo del ROI. En conclusión, se demuestran las mejoras que ofrece el social media en campos como la comunicación interna, gestión del conocimiento, formación e innovación. Y gracias a estas mejoras el aumento de la productividad y eficiencia del profesional y asimismo un potencial retorno de la inversión (ROI). ABSTRACT. This paper deals with the study of the implementation and development of the different platforms of social media: social networks and knowledge, blogs and collaborative tools in the corporate enterprise level. The study collects information technology consulting, articles and several social media platforms and an investigation into the question raised is performed. Analysis of 42 surveys of professionals from two big companies telecommunications in Spain are included. These two companies have one about 28000 employees and another with more than 300 employees at its Spanish subsidiaries. Both have a strong international presence. These two companies differ from other companies in the telecommunications sector they are betting in the implementation of social media in their internal processes. Furthermore, the study and analysis of usage statistics and a series of surveys on the wall of the corporate social network of a multinational telecommunications is included for three months. A new social culture enterprise is presented innovative in areas such as knowledge management, internal communications, training and innovation. And a quantitative vision into implementation of social media in the processes of a company is offered. They develops an exhibition where shown the process of studying the different social media platforms and application areas in the company, the study of the legal aspects of your application and use and implementation and development. A theoretical and practical analysis also exposed of calculation of return on investment (ROI) and finally an analysis of the information collected in surveys and statistical study of corporate social network. The survey data were analyzed using descriptive statistics based on graphs and contingency tables where waste and total percentages are calculated for analyze the dependence between the social media, efficiency, productivity and income statement, plus analysis of the contribution of social media on the mission, internal communication and knowledge management in the company. Also Calculations of chi-square distributions are conducted to demonstrate the dependence between of productivity and social media and the GAP that relates the importance and satisfaction level in social media. The theoretical and practical analysis parameters are the benefits, costs, flexibility and risk. The benefits are linked to productivity, knowledge management, human capital and internal processes. The costs are linked the software licensing, management, implementation and training. Based on these parameters was performed the study of a business model that represents a large ICT company in Spain. The data for the study are estimates within the reality, because the intention is not to know these real values but the theoretical and practical study and application of the method for calculating the ROI. Statistical analysis of the social network was made during or three months and was obtained the progress of social network use at events such as: number of active participants, messages posted, files uploaded, active groups and types and access platforms. Into study of statistical data of these events were obtained indicators of participation, activity and knowledge of the social network that are useful for calculating the ROI. In conclusion, the improvements offered by the social media in areas such as internal communication, knowledge management, training and innovation are shown. And thanks to these improvements increase the productivity and efficiency of professional and also a potential return on investment (ROI).

Social Networks Shape the Transmission Dynamics of Hepatitis C Virus

Hepatitis C virus (HCV) infects 170 million people worldwide, and is a major public health problem in Brazil, where over 1% of the population may be infected and where multiple viral genotypes co-circulate. Chronically infected individuals are both the source of transmission to others and are at risk for HCV-related diseases, such as liver cancer and cirrhosis. Before the adoption of anti-HCV control measures in blood banks, this virus was mainly transmitted via blood transfusion. Today, needle sharing among injecting drug users is the most common form of HCV transmission. Of particular importance is that HCV prevalence is growing in non-risk groups. Since there is no vaccine against HCV, it is important to determine the factors that control viral transmission in order to develop more efficient control measures. However, despite the health costs associated with HCV, the factors that determine the spread of virus at the epidemiological scale are often poorly understood. Here, we sequenced partial NS5b gene sequences sampled from blood samples collected from 591 patients in Sao Paulo state, Brazil. We show that different viral genotypes entered Sao Paulo at different times, grew at different rates, and are associated with different age groups and risk behaviors. In particular, subtype 1b is older and grew more slowly than subtypes 1a and 3a, and is associated with multiple age classes. In contrast, subtypes 1a and 3b are associated with younger people infected more recently, possibly with higher rates of sexual transmission. The transmission dynamics of HCV in Sao Paulo therefore vary by subtype and are determined by a combination of age, risk exposure and underlying social network. We conclude that social factors may play a key role in determining the rate and pattern of HCV spread, and should influence future intervention policies.

Lo-Fi matchmaking: A study of social pairing for backpackers

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.

Network dynamics in scientific knowledge acquisition: an analysis in three public universities in the state of Bahia

This paper aims to cast some light on the dynamics of knowledge networks in developing countries by analyzing the scientific production of the largest university in the Northeast of Brazil and its influence on some of the remaining regional research institutions in the state of Bahia. Using a methodology test to be employed in a larger project, the Universidade Federal da Bahia (UFBA) (Federal University of Bahia), the Universidade do Estado da Bahia (Uneb) (State of Bahia University) and the Universidade Estadual de Santa Cruz (Uesc)'s (Santa Cruz State University) scientific productions are discussed in one of their most traditionally expressive sectors in academic production - namely, the field of chemistry, using social network analysis of co-authorship networks to investigate the existence of small world phenomena and the importance of these phenomena in research performance in these three universities. The results already obtained through this research bring to light data of considerable interest concerning the scientific production in unconsolidated research universities. It shows the important participation of the UFBA network in the composition of the other two public universities research networks, indicating a possible occurrence of small world phenomena in the UFBA and Uesc networks, as well as the importance of individual researchers in consolidating research networks in peripheral universities. The article also hints that the methodology employed appears to be adequate insofar as scientific production may be used as a proxy for scientific knowledge.

Rede social académica

O processo de Bolonha apresenta directivas para a construção de um espaço europeu de ensino superior. A adopção destas directivas requer uma abordagem que favoreça, na prática, a mobilidade dos estudantes que têm dificuldades em compreenderem as oportunidades que lhes são oferecidas. Neste contexto, esta dissertação explora a hipótese de utilização de uma rede social para apoiar a mobilidade de estudantes no espaço europeu. No âmbito desta dissertação propõe-se um modelo de conhecimento para representar os membros de uma rede social vocacionada para apoiar cenários de mobilidade, designada por rede social académica. Este modelo foi obtido pela fusão da ontologia Academic Ontology to Support the Bologna Mobility Process com a ontologia Friend of a Friend Ontology. Para efeitos de avaliação experimental, foi criado um demonstrador numa rede social disponível publicamente na Internet que utiliza uma versão simplificada do modelo proposto. Os cenários usados nas experiências representam situações reais às quais foi aplicado um processo rudimentar de descoberta de conhecimento
