An attribute based access control scheme for secure sharing of electronic health records
2016
Electronic health records (EHRs) play a vital role in modern health industry, allowing the possibility of flexible sharing of health information in the quest of provisioning advanced and efficient healthcare services for the users. Although sharing of EHRs has significant benefits, given that such records contain lot of sensitive information, secure sharing of EHRs is of paramount importance. Thus, there is a need for the realization of sophisticated access control mechanisms for secure sharing of EHRs, which has attracted significant interest from the research community. The most prominent access control schemes for sharing of EHRs found in literature are role based and such solutions have…
No Reservations Required: Achieving Fairness between Wi-Fi and NR-U with Self-Deferral Only
2021
Wireless technologies coexisting in unlicensed bands should receive a fair share of the available channel resources, even when they use different access methods. We consider the problem of coexistence between Wi-Fi and New Radio Unlicensed (NR-U) nodes, which employ, respectively, a random and scheduled access scheme. The latter typically resorts to reservation signals (RSs), which allow keeping the control of the channel until the start of the next synchronized slot. This mechanism, although effective for increasing the channel access opportunities of scheduled-based nodes, is also a waste of channel resources. We investigate alternative solutions, based on self-deferral only. We built ana…

Déclaration des politiques des revues scientifiques françaises : un nouveau service via Mir@bel et Sherpa Romeo
2021
webinaire Médici #5 ; 50 participants; National audience; La formalisation par les revues scientifiques françaises de leur politique de publication en matière d'autoarchivage et de rediffusion voire réutilisation des contenus est essentielle dans le contexte de la politique nationale science ouverte. Non seulement il s'agit de décider de la diffusion mais il faut expliciter le cadre des autorisations et obligations au moyen de licences, de contrats, etc. Ces politiques déclarées par les éditeurs des revues sont agrégées via Sherpa Romeo ce qui en facilite la consultation et l'usage. Ce webinaire a pour objectif de faire connaître le rôle du réseau Mir@bel dans la déclaration de ces politiqu…
Investigación pediátrica española financiada: contribución de Anales de Pediatría a su difusión
2017
Resumen: Objetivo: Identificar la investigación pediátrica española financiada publicada en revistas generales pediátricas incluidas en la WoS (2010-2014) y la de Anales de Pediatría (AP). Explorar la relación de la financiación con el prestigio de las revistas y describir sus condiciones para cumplir los mandatos de acceso abierto. Material y método: La financiación de los artículos publicados en revistas pediátricas generales se identificó utilizando el campo Agencia Financiadora de la WoS y revisando el documento original para AP. Para AP se identificaron las entidades financiadoras de los AF y se valoró la diferencia en la citación de los AF y los no financiados mediante test no paramét…
Atlas of Variations in Medical Practice in Spain: The Spanish National Health Service under scrutiny
2012
Early in the 2000s, a countrywide health services research initiative was launched under the acronym of Atlas VPM: Atlas of Variations in Medical Practice in the Spanish National Health System. This initiative aimed at describing systematic and unwarranted variations in medical practice at geographic level-building upon the seminal experience of the Dartmouth Atlas of Health Care. The paper aims at explaining the Spanish Atlas experience, built upon the pioneer Dartmouth inspiration. A few selected examples will be used along the following sections to illustrate the outlined conceptual framework, the different factors that may affect variation, and some methodological challenges.
Mapping the relation between University access test and student’s university performance
2018
The access test is the most used tool to evaluate the initial preparation of an italian student before enrolling at the university. Although the necessity to select the most deserving students seem unquestionably reasonable, we have to wonder if it appears to be a good predictor of university performance. In order to answer this question, the university careers of the students enrolled at two Degree Courses at the University of Palermo (academic year 2013/2014) were analysed. The very aim of this paper is to propose a graphical tool, the Student Efficiency Nomogram, that shows the access test scores together with the first-year performance of the student.
Reasons for Older Adult Participation in University Programs in Spain
2010
This study examined the reasons expressed by older adults for attending a university program in Barcelona (Spain). Results were based on the responses of 36 elders to questions from a semistructured interview. These were (a) reasons for joining a university course and (b) factors that prevent enrolling in that course. Participants mentioned more expressive than instrumental reasons for participating in a university program. Most mentioned barriers to entering university that were lack of interest, lack of self-confidence, health problems, and limited information. These results are discussed in the context of new strategies to improve university courses aimed at the elderly.

Do serifs provide an advantage in the recognition of written words?
2011
A neglected issue in the literature on visual-word recognition is the careful examination of parameters such as font, size, or interletter/interword spacing on reading times. Here we analysed whether serifs (i.e., the small features at the end of strokes) play a role in lexical access. Traditionally, serif fonts have been considered easier to read than sans serif fonts, but prior empirical evidence is scarce and inconclusive. Here we conducted a lexical decision experiment (i.e., a word/nonword discrimination task) in which we compared words from the same family (Lucida) either with a serif font or with a sans serif font—in both a block list and a mixed list. Results showed a small, but sig…
