Aquest projecte té com a propòsit crear una ràdio musical participativa amb difusió online i FM on a partir d’una interfície web l’usuari pugui participar-hi activament votant les cançons que hi sonaran. A més a més els usuaris registrats gaudiran d’una xarxa social on podran fer amistats i deixa’ls-hi comentaris. Primer de tot faig una ràpida introducció a l’estat de l’art de les ràdios actuals, a continuació analitzo els requeriments, especifico el comportament desitjat del sistema, explico detalladament el disseny i l’ implementació i, per últim, faig un seguit de proves de les quals n’extrec les conclusions.

L'apport de la trace matérielle dans l'enquête criminelle: évaluation de la contribution des liens chimiques issus du profilage de produits stupéfiants par l'analyse des réseaux sociaux

La trace matérielle dispose d'un potentiel incomparable pour mettre en relation des indices et occupe souvent une place centrale lors du procès pénal (Ribaux et Margot, 2008). Au delà de son rôle élémentaire en tant qu'élément de preuve, la trace matérielle véhicule de nombreuses autres informations encore trop peu exploitées en matière d'investigation ou pour servir de base au renseignement criminel. C'est particulièrement le cas des liens chimiques découverts grâce au profilage physico-chimique de produits stupéfiants saisis par les autorités. Le but de ce travail est d'estimer l'apport de ces liens chimiques à la perception de la structure des réseaux criminels. Pour ce faire, nous nous appuyons sur des modèles d'analyse des réseaux sociaux (SNA, Social Network Analysis). Ces modèles sont toujours plus utilisés pour traiter des affaires qui relèvent de la criminalité organisée, notamment pour comprendre la structure et la dynamique de ces réseaux d'acteurs. L'analyse des réseaux sociaux (SNA) procède par le calcul de différents indicateurs pour mettre en évidence des éléments pertinents de leur structure et leurs acteurs clés. Par exemple, l'identification des vulnérabilités de l'organisation et des mécanismes mis en place par les acteurs pourra orienter les actions policières. Cette recherche se base sur une enquête concernant un réseau international de trafic de produits stupéfiants. En plus des autres informations d'enquête traditionnellement disponibles, des liens chimiques ont été mis en évidence par le profilage de l'héroïne saisie à différents endroits et périodes, puis utilisés par les enquêteurs. Cette recherche consiste à utiliser les indicateurs SNA pour évaluer l'influence de ces liens chimiques sur la structure de ce réseau construit à partir des autres indices. Les premiers résultats montrent que les liens chimiques sont cohérents avec les autres types de relations, et qu'ils tendent, à eux seuls, à mettre en évidence les positions centrales de certains acteurs clés. De plus, l'intégration de ces liens renforce les centralités de certains acteurs et permet ainsi de les considérer de manière plus centrale qu'ils ne l'étaient auparavant. Enfin, ces premiers résultats laissent entrevoir des perspectives intéressantes notamment au travers de la pondération de ces relations afin d'évaluer de manière plus globale l'apport du potentiel informatif de ce type de renseignement.

Having Your Cake and Eating It, Too: Can Regulatory Agencies Be Both Independent and Accountable?

Independent regulatory agencies (IRAs) were created in various sectors and on different governmental levels to implement liberalization policies. This paper investigates the link between IRAs' independence, which is said to promote regulatory credibility and the use of technical expertise, and their accountability, which is related to the need for controlling and legitimizing independent regulators. The literature on the regulatory state anticipates a positive relation between the independence and accountability of IRAs, but systematic empirical evidence is still lacking. To tackle this question, this paper measures and compares the independence and the accountability of IRAs in three differentially liberalized sectors in Switzerland (telecommunications, electricity and railways). With the application of Social Network Analysis, this piece of research shows that IRAs can be de facto independent and accountable at the same time, but the two features do not necessarily co-evolve in the same direction.

El temps del mal: l’experiència i la gestió de la cronicitat en adults

El temps del mal. L’experiència i la gestió de la cronicitat en adults. El principal objectiu d’aquesta recerca és l’estudi de l’experiència i la gestió diària de la cronicitat, entenent-la com a categoria analítica que engloba els processos de malalties i/o malestars crònics, biomèdicament diagnosticats o no, que perduren en el temps. La recerca es centra en adults entre 30 i 50 anys amb problemes crònics de salut que impliquin algun tipus de discapacitat i/o dependència (a nivell moderat), i s’ubica en l’àmbit urbà i en la comunitat autònoma de Catalunya (dins del context de l’estat Espanyol). L’estudi analitzarà la gestió individual i social de la cronicitat a través dels itineraris terapèutics i pràctiques assistencials dels processos de salut/malaltia/atenció prenent l’autoatenció com a principal categoria analítica. Per altra banda, es descriurà el rol dels serveis assistencials de la sanitat pública i dels serveis socials, per veure com es duu a terme la gestió – polítiques públiques - de la cronicitat en un país amb estat del benestar com Espanya. L’experiència de la cronicitat s’explorarà a través de les narratives de la vivència de la malaltia/malestar tan com a representació cultural – que dóna compte de les relacions, interaccions i respostes socials – i des d’una perspectiva fenomenològica que ens permet comprendre la naturalesa del patiment en l’experiència viscuda del cos malalt. Aquesta recerca espera poder fer aportacions pertinents que contribueixin des de l’antropologia però amb la intenció d’obrir un diàleg públic i interdisciplinar – professionals de la salut, experts en polítiques públiques i públic en general - a la resolució de l’actual problema de salut pública d’increment de cronicitat. El model públic d’atenció a la salut espanyol es va dissenyar per resoldre problemes de salut aguts, malgrat la major part dels usuaris actuals presentes problemes de salut crònics. L’actual crisi econòmica que amenaça aquest pilar de l’estat del benestar és, alhora, una oportunitat per replantejar-ho.

Correlations between major risk factors and closely related Mycobacterium tuberculosis isolates grouped by three current enotyping procedures: a population-based study in northeast Mexico

The characteristics of tuberculosis (TB) patients related to a chain of recent TB transmissions were investigated. Mycobacterium tuberculosis (MTB) isolates (120) were genotyped using the restriction fragment length polymorphism-IS6110 (R), spacer oligotyping (S) and mycobacterial interspersed repetitive units-variable number of tandem repeats (M) methods. The MTB isolates were clustered and the clusters were grouped according to the similarities of their genotypes. Spearman’s rank correlation coefficients between the groups of MTB isolates with similar genotypes and those patient characteristics indicating a risk for a pulmonary TB (PTB) chain transmission were ana- lysed. The isolates showing similar genotypes were distributed as follows: SMR (5%), SM (12.5%), SR (1.67%), MR (0%), S (46.67%), M (5%) and R (0%). The remaining 35 cases were orphans. SMR exhibited a significant correlation (p < 0.05) with visits to clinics, municipalities and comorbidities (primarily diabetes mellitus). S correlated with drug consumption and M with comorbidities. SMR is needed to identify a social network in metropolitan areas for PTB transmission and S and M are able to detect risk factors as secondary components of a transmission chain of TB.

El blog y otras herramientas comunicativas de la biblioteca del Área de Gestión Sanitaria Este de Málaga - Axarquía

In 2006 the Library of the Andalusian Public Health System (BVSSPA) is constituted as a Virtual Library which provides Resources and Services that are accessed through inter-hospital local area network (corporate intranet) and Internet. On the other hand, the Hospital de la Axarquia still did not have any institutional or self-presence on the Internet and the librarian ask the need to create a space for communication with the "digital users" of the Library of the area through a website. MATERIALS AND METHODS. The reasons why we opted for a blog were: -It was necessary to make no financial outlay for its establishment. It allowed for great versatility, both in its administration and in its management by users. -The ability to compile on the same platform different Web 2.0 communication tools. Between different options available we chose Blogger Google Inc. The blog allowed entry to the 2.0 services or Social Web in the library. The benefits offered were many, especially the visibility of the service and communication with the user. 2.0 tools that have been incorporated into the library are: content syndication (RSS) which allowed users to stay informed about updates to the blog. Share documents and other multimedia as presentations through SlideShare, images through Flickr or Picasa, or videos (YouTube). And the presence on social network like Facebook and Twitter. RESULTS. The analysis of the activity we has been traking by Google Analytics tool, helping to determine the number of blog visits. Since its stablishment, on November 17th 2006, until November 29th 2010 the blog has received 15,787 visitors, 38,422 page views were consulted, at each visit on average 2.4 pages were consulted and each visit has an average stay at the site of 4'31''. DISCUSSION. The blog has served as a communication and information tool with the user. Since the creation of the blog we have incorporated technologies and tools to interact with the user. With all the tools used we have applied the concept of "open source" and the contents were generated from the activities organized in the Knowledge Management Unit from the anatomo-clinical sessions, the training activities, dissemination events, etc. The result has been the customization of library services, contextualized in the Knowledge Management Unit - Axarquia. In social networks we have shared information and files with the professionals and the community. CONCLUSIONS. The blog has allowed us to explore technologies that allow us to communicate with the user and the community, disseminate information and documents with the participation of users and become the "Interactive Library" we aspire to be.

Networks of PhD Students and Academic Performance: A Comparison across Countries

In this article we compare regression models obtained to predict PhD students’ academic performance in the universities of Girona (Spain) and Slovenia. Explanatory variables are characteristics of PhD student’s research group understood as an egocentered social network, background and attitudinal characteristics of the PhD students and some characteristics of the supervisors. Academic performance was measured by the weighted number of publications. Two web questionnaires were designed, one for PhD students and one for their supervisors and other research group members. Most of the variables were easily comparable across universities due to the careful translation procedure and pre-tests. When direct comparison was notpossible we created comparable indicators. We used a regression model in which the country was introduced as a dummy coded variable including all possible interaction effects. The optimal transformations of the main and interaction variables are discussed. Some differences between Slovenian and Girona universities emerge. Some variables like supervisor’s performance and motivation for autonomy prior to starting the PhD have the same positive effect on the PhD student’s performance in both countries. On the other hand, variables like too close supervision by the supervisor and having children have a negative influence in both countries. However, we find differences between countries when we observe the motivation for research prior to starting the PhD which increases performance in Slovenia but not in Girona. As regards network variables, frequency of supervisor advice increases performance in Slovenia and decreases it in Girona. The negative effect in Girona could be explained by the fact that additional contacts of the PhD student with his/her supervisor might indicate a higher workload in addition to or instead of a better advice about the dissertation. The number of external student’s advice relationships and social support mean contact intensity are not significant in Girona, but they have a negative effect in Slovenia. We might explain the negative effect of external advice relationships in Slovenia by saying that a lot of external advice may actually result from a lack of the more relevant internal advice

Human-Computer Interaction with older people through ethnographical lenses: everyday interactions with ICT

Report for the scientific sojourn carried out at the School of Computing of the University of Dundee, United Kingdom, from 2010 to 2012. This document is a scientific report of the work done, main results, publications and accomplishment of the objectives of the 2-year post-doctoral research project with reference number BP-A 00239. The project has addressed the topic of older people (60+) and Information and Communication Technologies (ICT), which is a topic of growing social and research interest, from a Human-Computer Interaction perspective. Over a 2-year period (June 2010-June 2012), we have conducted classical ethnography of ICT use in a computer clubhouse in Scotland, addressing interaction barriers and strategies, social sharing practices in Social Network Sites, and ICT learning, and carried out rapid ethnographical studies related to geo-enabled ICT and e-government services towards supporting independent living and active ageing. The main results have provided a much deeper understanding of (i) the everyday use of Computer-Mediated Communication tools, such as video-chats and blogs, and its evolution as older people’s experience with ICT increases over time, (ii) cross-cultural aspects of ICT use in the north and south of Europe, (iii) the relevance of cognition over vision in interacting with geographical information and a wide range of ICT tools, despite common stereotypes (e.g. make things bigger), (iv) the important relationship offline-online to provide older people with socially inclusive and meaningful eservices for independent living and active ageing, (v) how older people carry out social sharing practices in the popular YouTube, (vi) their user experiences and (vii) the challenges they face in ICT learning and the strategies they use to become successful ICT learners over time. The research conducted in this project has been published in 17 papers, 4 in journals – two of which in JCR, 5 in conferences, 4 in workshops and 4 in magazines. Other public output consists of 10 invited talks and seminars.

From Support to Control : A Configurational Perspective on Conjugal Quality

The topic of conjugal quality provides an empirical illustration of the relevance of the configurational perspective on families. Based on a longitudinal sample of 1,534 couples living in Switzerland drawn from the study "Social Stratification, Cohesion and Conflict in Contemporary Families", we show that various types of interdependencies with relatives and friends promote distinct conflict management strategies for couples as well as unequal levels of conjugal quality. We find that configurations characterized by supportive and non-interfering relationships with relatives and friends for both partners are associated with higher conjugal quality, while configurations characterized by interference are associated with lower conjugal quality.

Kinship in entrepreneur networks: Performance effects of resource assembly in Africa

We examine the relationship between structural social capital, resource assembly, and firm performance of entrepreneurs in Africa. We posit that social capital primarily composed of kinship or family ties helps the entrepreneur to raise resources, but it does so at a cost. Using data drawn from small firms in Kampala, Uganda, we explore how shared identity among the entrepreneur's social network moderates this relationship. A large network contributed a higher quantity of resources raised, but at a higher cost when shared identity was high. We discuss the implications of these findings for the role of family ties and social capital in resource assembly, with an emphasis on developing economies.
