Online drawings for dementia diagnose: in-air and pressure information analysis

In this paper we present experimental results comparing on-line drawings for control population (left and right hand) as well as Alzheimer disease patients. The drawings have been acquired by means of a digitizing tablet, which acquires time information angles and pressures. Experimental measures based on pressure and in-air movements appear to be significantly different for both groups, even when control population performs the tasks with the non-dominant hand.

Online and Offline Participation at the Local Level : A Quantitative Analysis of the Catalan Municipalities

This paper presents a first analysis on local electronic participatory experiences in Catalonia. The analysis is based on a database constructed and collected by the authors. The paper carries out an explanatory analysis of local initiatives in eparticipationand off line participation taking into account political variables (usually not considered in this kind of analysis) but also classical socio-economic variables that characterise municipalities. Hence, we add a quantitative analysis to the numerous case studies on local e-participation experiences. We have chosen Catalonia because is one of the European regions with more initiatives and one that has enjoyed considerable local governmental support to citizen participation initiatives since the 80s. The paper offers a characterisation of these experiences and a first explanatory analysis, considering: i) the institutional context in which these experiences are embedded, ii) the characteristics of the citizen participation processes and mechanisms on-line, and iii) a set of explanatory variables composed by the population size, thepolitical adscription of the mayor, the electoral abstention rate, age, income and level ofeducation in the municipality. The model that we present is explanatory for the municipalities with more than 20,000 inhabitants but it is not for the fewer than 20,000inhabitants. Actually, the number of participatory activities developed by these last municipalities is very low. Among all the variables, population size becomes the mostinfluential variable. Political variables such as political party of the mayor and the localabstention rate have a certain influence but that have to be controlled by population size.

Online and Offline Participation at the Local level: A Quantitative Analysis of the Catalan Municipalities

This article presents an analysis on local participatory experiences in Catalonia,both online and in-person. The analysis is based on a database set up by theauthors. The article carries out an explanatory analysis of local participatoryinitiatives (on- and offline) taking into account political variables (not usually con-sidered in this kind of analysis) and also classical socio-economic variables thatcharacterize municipalities. Hence, we add a quantitative analysis to the numerouscase studies on local e-participation experiences. We have chosen Catalonia becauseit is one of the European regions with more initiatives and a considerable localgovernment support for citizen participation initiatives since the 1980s. Thearticle offers a characterization of these experiences and an explanatory analysis,considering: (i) the institutional context in which these experiences are embedded,(ii) the citizen participation processes and mechanisms online and (iii) a set ofexplanatory variables composed of the population size and the province to whichthe municipality belongs, the political tendency of the mayor, the electoral absten-tion rate, age, income, level of education, broadband connection and users of theInternet in the municipality. The model that we present is explanatory for munici-palities with more than 20,000 inhabitants but it is not for fewer than 20,000inhabitants. Actually, the majority of these latter municipalities have not developedany participatory activities. Among all the variables, population size is the mostinfluential variable and affects the influence of other variables, such as the politicalparty of the mayor, the local abstention rate and the province.

Web per a psicologia i teràpia online Espai Nirvana

Aquest Treball de Final de Carrera engloba l'anàlisi, el disseny i la implementació d'una aplicació web per a psicologia i teràpia online. L'enginyeria d'aquest programari està basada en la tècnica d'orientació a objectes, dins l'estàndard UML. Els aspectes generals de l'anàlisi i disseny s'han desenvolupat amb un cicle de vida en cascada, per tenir una bona base de partida i poder confeccionar una planificació en el temps. La fase de implementació, està basada en un cicle de vida iteratiu e incremental, implementant a cada iteració una petita part amb autonomia que correspon a un cas d'ús. Com a llenguatge de desenvolupament he escollit Java , i com a arquitectura de l'aplicació J2EE, degut a la seva robustesa i a que en l'actualitat, té un fort posicionament en aplicacions web i en xarxa, arribant a ser un estàndard en l'entorn distribuït d'aplicacions empresarials a Internet. En l'estratègia en el disseny i per donar solucions efectives a problemes tipificats, he fet servir el patró MVC, que a més, ha incrementat considerablement la reusabilitat i efectivitat del codi i estructura de la programació. Per a la implementació he incorporat el framework Struts2, que basa la seva arquitectura en el patró MVC, i que ha facilitat molt el treball ja que ha donat solucions a problemes generals estàndard i altres de baix nivell, i ha permès focalitzar els esforços en donar solució a qüestions més particulars i específiques del projecte. En l'accés transparent a les dades he optat per Hibernate3, una poderosa eina que enllaça el món relacional de les BBDD amb el mon de l'orientació a objectes de les classes de les aplicacions. I com a SGBD per a la persistència de dades, he fet servir Oracle 10g XE, també tot un referent en la indústria, i un dels més complets.

A Method and Tool to Support the Analysis and Enhance the Understanding of Peer-to-Peer Learning Experiences

In this paper we look at how a web-based social software can be used to make qualitative data analysis of online peer-to-peer learning experiences. Specifically, we propose to use Cohere, a web-based social sense-making tool, to observe, track, annotate and visualize discussion group activities in online courses. We define a specific methodology for data observation and structuring, and present results of the analysis of peer interactions conducted in discussion forum in a real case study of a P2PU course. Finally we discuss how network visualization and analysis can be used to gather a better understanding of the peer-to-peer learning experience. To do so, we provide preliminary insights on the social, dialogical and conceptual connections that have been generated within one online discussion group.

Three-dimensional morphological analysis of intracranial aneurysms: a fully automated method for aneurysm sac isolation and quantification

Morphological descriptors are practical and essential biomarkers for diagnosis andtreatment selection for intracranial aneurysm management according to the current guidelinesin use. Nevertheless, relatively little work has been dedicated to improve the three-dimensionalquanti cation of aneurysmal morphology, automate the analysis, and hence reduce the inherentintra- and inter-observer variability of manual analysis. In this paper we propose a methodologyfor the automated isolation and morphological quanti cation of saccular intracranial aneurysmsbased on a 3D representation of the vascular anatomy.

Analysis of the folksonomy of freesound

User generated content shared in online communities is often described using collaborative tagging systems where users assign labels to content resources. As a result, a folksonomy emerges that relates a number of tags with the resources they label and the users that have used them. In this paper we analyze the folksonomy of Freesound, an online audio clip sharing site which contains more than two million users and 150,000 user-contributed sound samplescovering a wide variety of sounds. By following methodologies taken from similar studies, we compute some metrics that characterize the folksonomy both at the globallevel and at the tag level. In this manner, we are able to betterunderstand the behavior of the folksonomy as a whole, and also obtain some indicators that can be used as metadata for describing tags themselves. We expect that such a methodology for characterizing folksonomies can be useful to support processes such as tag recommendation or automatic annotation of online resources.

Redes digitales de comunicación, participación ciudadana y periodismo online durante la primavera árabe: Túnez, 17 de diciembre de 2010-23 de octubre de 2011.

El presente proyecto de investigación se presenta como trabajo final del Máster en Estudis Avançats en Comunicació Social y pretende sentar las bases de la futura tesis doctoral. Se plantea una investigación que tiene como objetivo determinar la capacidad que tuvo el uso de las redes digitales de comunicación para modificar la esfera pública durante la primavera árabe en Túnez y el posterior proceso de Transición llevado a cabo. Para ello la investigación se aborda desde tres conceptos clave: el pluralismo mediático, la relevancia mediàtica y los procesos comunicativos. La investigación se abordará triangulando los métodos cuantitativo y cualitativo y se propone como técnica el anàlisis de contenido sobre la nueva legislación tunecina en materia de Políticas de Comunicación, así como del contenido generado por los usuarios en las redes digitales de comunicación y las noticias de medios de referencia online árabes (3) y occidentales (4) en relación con el objeto de estudio.

La subtitulación amateur: la subtitulación amateur de series online: el caso de Lost

Debido a su gran repercusión y rápido ritmo de expansión, resulta obvio que la subtitulación amateur se configura como uno de los fenómenos más interesantes y novedosos de los estudios teóricos y prácticos de la investigación traductológica. Por este motivo, el objetivo principal del presente trabajo es el de conocer y estudiar más en profundidad dicho fenómeno, así como analizar la calidad de estos subtítulos con relación a los profesionales a través de un análisis comparativo de materiales reales de la serie norteamericana Lost. Por otro lado, y a la vista de las conclusiones, también se reflexiona acerca del estado actual de la subtitulación interlingüística, así como de la viabilidad de llevar a cabo una modernización de la disciplina mediante el establecimiento, renovación y diversificación de nuevas y existentes modalidades, junto con las repercusiones académicas, sociológicas y profesionales que ello acarrearía.

Characterization of the freesound online community

There are many online communities with membergenerated and openly available multimedia content. Their successdepends on having active contributing users and on producing useful content. With this criterion, the community of sound practitioners that has emerged in Freesound is a successful case of interest to be studied. But to understand it and support it further we need an appropriate analysis methodology. In this paper we propose some qualitative and quantitative approaches for its characterization, focusing on the analysis of organizational structure, shared goals, user interactions and vocabulary sharing. We think that the proposed approach can be applied to otheronline communities with similar characteristics.

The Coverage of the European independence movements from a Canadian perspective: Comparisons of the francophone online press in Quebec with the English Canadian press on the independence movements in Scotland and Catalonia

This research paper provides the basis of a future doctoral thesison the construction of foreign news. We aim to highlight similarities and differences in the online news coverage of the nationalist movments in Scotland and Catalonia in the Canadian Anglophone and Francophone press. Through a qualitative and quantitative content analysis of The Montreal Gazette, The National Post, The Globe and Mail, Le Devoir and La Presse, we attempt to show the frames used in the coverage of the political developments in both “stateless regions” from January 2011 to September 2014, when a referendum on the constitutional status of Scotland has beenagreed on. In parallel to the analysis of daily online newspapers, we will use semi-structured interviews of journalists from each news organization to obtain more in-depth knowledge of the factors influencing the construction of news. Lastly, we want to find out to the extent to which the coverage on the nationalist movements in Scotland and Catalonia serve to revive the debate on the independence question of Québec

Redefining dropping out in online higher education: a case study from the UOC

In recent years, studies into the reasons for dropping out of higher education (including online education) have been undertaken with greater regularity, parallel to the rise in the relative weight of this type of education, compared with brick-and-mortar education. However, the work invested in characterising the students who drop out of education, compared with those who do not, appears not to have had the same relevance as that invested in the analysis of the causes. The definition of dropping out is very sensitive to the context. In this article, we reach a purely empirical definition of student dropping out, based on the probability of not continuing a specific academic programme following several consecutive semesters of "theoretical break". Dropping out should be properly defined before analysing its causes, as well as comparing the drop-out rates between the different online programmes, or between online and on-campus ones. Our results show that there are significant differences among programmes, depending on their theoretical extension, but not their domain of knowledge.
