Comunicació presentada a la EMOOCs 2017 Conference, celebrada els dies 22 a 26 de maig de 2017 a Leganés, Espanya., A range of data analytics is provided to educators about the profile, behavior and satisfaction of students participating in a Massive Open Online Course (MOOC). However, limited research has been conducted on how this informs the redesign of next MOOC editions. This work-in-progress paper presents a study of 4 MOOC educators from Universitat Pompeu Fabra regarding 3 MOOCs offered on the FutureLearn platform. The objective was to evaluate the usefulness and understandability of different types of data analytics of the courses they have offered with respect to specific monitoring goals. Preliminary results show that educators perceived the same information sources and data visualizations differently, satisfaction surveys and comments in the forum were among the most useful information but it was difficult to associate data analytics with the monitoring goals. Further studies for the alignment of educators´ monitoring needs for redesign purposes and the development of appropriate support tools are suggested., This research is partly funded by RecerCaixa and the Spanish Ministry of Economy and Competitiveness under RESET (TIN2014-53199-C3-3-R) and the Maria de Maeztu Units of Excellence Programme (MDM-2015-0502).

A datalog framework for modeling relationship-based access control policies

  • Pasarella Sánchez, Ana Edelmira
  • Lobo, Jorge
Comunicació presentada al SACMAT'17. 22nd ACM Symposium on Access Control Models and Technologies, celebrat els dies 21 a 23 de juny de 2017 a Indianapolis, EUA., Relationships like friendship to limit access to resources have been part of social network applications since their beginnings. Describing access control policies in terms of relationships is not particular to social networks and it arises naturally in many situations. Hence, we have recently seen several proposals formalizing different Relationship-based Access Control (ReBAC) models. In this paper, we introduce a class of Datalog programs suitable for modeling ReBAC and argue that this class of programs, that we called ReBAC Datalog policies, provides a very general framework to specify and implement ReBAC policies. To support our claim, we first formalize the merging of two recent proposals for modeling ReBAC, one based on hybrid logic and the other one based on path regular expressions. We present extensions to handle negative authorizations and temporal policies. We describe mechanism for policy analysis, and then discuss the feasibility of using Datalog-based systems as implementations., Edelmira Pasarella was partially supported by the Spanish Ministry for Economy and Competitiveness (MINECO) and the European Union (FEDER funds) under Grant Ref.: TIN2013-46181-C2-1-R COMMAS.

Sap la gent quin és el model de recollida selectiva porta a porta? Ajuda aquest sistema a la preservació del medi ambient o es tracta simplement d’un mite? Això és el que ens vam preguntar nosaltres a l’inici del treball. Aquest model s’aplica des del mes de novembre del 2008 a Palau-solità i Plegamans, un municipi del Vallès Occidental. A partir de l’estudi d’aquest cas pràctic hem volgut analitzar la viabilitat d’aquest sistema i la seva acceptació social. Comprovarem que aquest sistema és deficitari i que els impostos juguen un paper molt important en el finançament del sistema actual.Un altre objectiu és comparar el sistema porta a porta que hi ha actualment amb el que es va proposar en l’anterior legislatura, basat en la divisió del poble en dues zones amb models de recollida diferents. Concretament, ens interessa saber si va ser una bona idea canviar de sistema i, tal com veurem més endavant, la resposta és afirmativa.També volem saber si aquest model es podria aplicar a altres municipis amb densitat i poblacions diferents. A través d’aquest treball, veurem que la densitat de la població és un dels factors més importants, malgrat que influeixen altres elements (per exemple, l’acceptació social).

The impact of feedback type regarding behavior on shaping spending credit-card behavior

Treball de Fi de Grau en Economia. Curs 2013-2014, Tutor: Gert Cornelisen, Payment methods have been proven to affect spending behavior. More precisely, when/nindividuals use credit cards tend to overspend and to underestimate their past expenses. However, there is little research about the role that the additional services provided by financial institution have in shaping consumption patterns. This paper analyze how one of these services –the text message that banks send to their clients each time they make a payment using a credit card– affects spending control. A review of the previous literature is considered, and an experiment is hold to show support for the proposed theoretical framework. Our findings suggest that the information stated in these SMS are a source of variance in the overall expenses.

This article explores the relationship between institutional funding for research and community-based or co-enquiry research practice. It examines the implementation of co-enquiry research in the COMBIOSERVE project, which was funded by the European Commission's Seventh Framework Programme for research and innovation, between the years 2012 and 2015. Research partnerships between Latin American and European civil society organisations, research institutions, and Latin American rural communities are analysed. Challenges for effective collaboration in co-enquiry and lessons learned for research policy and practice are outlined. Based on our case study we suggest that: (1) the established values and practices of academia seem largely unfavourable towards alternative forms of research, such as co-enquiry; (2) the policies and administrative practices of this European Commission funding are unsuitable for adopting participatory forms of enquiry; and (3) the approach to research funding supports short engagements with communities whereas long-term collaborations are more desirable. Based on our case study, we propose more flexible funding models that support face-to-face meetings between researchers and communities from the time of proposal drafting, adaptation of research processes to local dynamics, adaptation of administrative processes to the capacities of all participants, and potential for long-term collaborations. Large-scale funding bodies such as European Commission research programmes are leaders in the evolution of research policy and practice. They have the power and the opportunity to publicly acknowledge the value of partnerships with civil society organisations and communities, actively support co-enquiry, and foment interest in innovative forms of research., info:eu-repo/semantics/publishedVersion

CTDquerier: a bioconductor R package for Comparative Toxicogenomics DatabaseTM data extraction, visualization and enrichment of environmental and toxicological studies

  • Hernandez-Ferrer, Carles, 1987-
  • González Ruiz, Juan Ramón
SUMMARY: Biomedical studies currently include a large volume of genomic and environmental factors for studying the etiology of human diseases. R/Bioconductor projects provide several tools for performing enrichment analysis at gene-pathway level, allowing researchers to develop novel hypotheses. However, there is a need to perform similar analyses at the chemicals-genes or chemicals-diseases levels, to provide complementary knowledge of the causal path between chemicals and diseases. While the Comparative Toxicogenomics DatabaseTM (CTD) provides information about these relationships, there is no software for integrating it into R/Bioconductor analysis pipelines. CTDquerier helps users to easily download CTD data and integrate it in the R/Bioconductor framework. The package also contains functions for visualizing CTD data and performing enrichment analyses. We illustrate how to use the package with a real data analysis of asthma-related genes. CTDquerier is a flexible and easy-to-use Bioconductor package that provides novel hypothesis about the relationships between chemicals and diseases. AVAILABILITY AND IMPLEMENTATION: CTDquerier R package is available through Bioconductor and its development version at https://github.com/isglobal-brge/CTDquerier., This work was supported by the Spanish Ministry of Economy and Competitiveness [MTM2015-68140-R] and the HELIX Project supported by European Commission FP7 [GA#308333].

BACKGROUND: Change in the prevalence of asthma-like symptoms in populations of ageing adults is likely to be influenced by smoking, asthma treatment and atopy. METHODS: The European Community Respiratory Health Survey collected information on prevalent asthma-like symptoms from representative samples of adults aged 20-44 years (29 centres in 13 European countries and Australia) at baseline and 10 and 20 years later (n=7844). Net changes in symptom prevalence were determined using generalised estimating equations (accounting for non-response through inverse probability weighting), followed by meta-analysis of centre level estimates. FINDINGS: Over 20 years the prevalence of 'wheeze' and 'wheeze in the absence of a cold' decreased (-2.4%, 95% CI -3.5 to -1.3%; -1.5%, 95% CI -2.4 to -0.6%, respectively) but the prevalence of asthma attacks, use of asthma medication and hay fever/nasal allergies increased (0.6%, 95% CI 0.1 to 1.11; 3.6%, 95% CI 3.0 to 4.2; 2.7%, 95% CI 1.7 to 3.7). Changes were similar in the first 10 years compared with the second 10 years, except for hay fever/nasal allergies (increase seen in the first 10 years only). Decreases in these wheeze-related symptoms were largely seen in the group who gave up smoking, and were seen in those who reported hay fever/nasal allergies at baseline. INTERPRETATION: European adults born between 1946 and 1970 have, over the last 20 years, experienced less wheeze, although they were more likely to report asthma attacks, use of asthma medication and hay fever. Decrease in wheeze is largely attributable to smoking cessation, rather than improved treatment of asthma. It may also be influenced by reductions in atopy with ageing.

Data de publicació electrònica: 19-04-2018, Lifespan varies dramatically among species, but the biological basis is not well understood. Previous studies in model organisms revealed the importance of nutrient sensing, mTOR, NAD/sirtuins, and insulin/IGF1 signaling in lifespan control. By studying life‐history traits and transcriptomes of 14 Drosophila species differing more than sixfold in lifespan, we explored expression divergence and identified genes and processes that correlate with longevity. These longevity signatures suggested that longer‐lived flies upregulate fatty acid metabolism, downregulate neuronal system development and activin signaling, and alter dynamics of RNA splicing. Interestingly, these gene expression patterns resembled those of flies under dietary restriction and several other lifespan‐extending interventions, although on the individual gene level, there was no significant overlap with genes previously reported to have lifespan‐extension effects. We experimentally tested the lifespan regulation potential of several candidate genes and found no consistent effects, suggesting that individual genes generally do not explain the observed longevity patterns. Instead, it appears that lifespan regulation across species is modulated by complex relationships at the system level represented by global gene expression
