Potencialidades de Google Maps en la investigación social aplicada
2019
In recent years, Google has devoted resources to build a complete map of the world. They constantly scan the territory, collecting a large amount of data that provides updated and complete geographic information. This allows us to have an interoperable map that provides the end user with a search tool, not only of routes but also of shops, equipment and any type of geo-referenced information. In addition, Google Maps provides a series of Application Programming Interface (API), which provides a library of set of subroutines, functions and procedures (in object-oriented programming) that can be used by other software to automate the extraction of information of the Google platform. These fre…
The (im)possible success of disadvantaged students. Reflections on education, migration and social change
2019
The paper focuses on the ?unexpected pathways? of successful students with an immigrant background: these biographical routes, that seems socially impossible, raise theoretical issues around the individual-society, actor-structure relationship. Disadvantaged students who succeed represent a sociological challenge in the attempt to understand atypical situations and to identify the institutional processes and the structural opportunities that facilitate them, reducing ethnic inequalities in education. This framework is the starting point of the Su.Per. project (Success in educational pathways of students with immigrant background), based on the collection of written autobiographies of 65 imm…
Past and present work practices of European interventional cardiologists in the context of radiation protection of the eye lens—results of the EURALO…
2018
International audience; This paper investigates over five decades of work practices in interventional cardiology, with an emphasis on radiation protection. The analysis is based on data from more than 400 cardiologists from various European countries recruited for a EURALOC study and collected in the period from 2014 to 2016. Information on the types of procedures performed and their annual mean number, fluoroscopy time, access site choice, x-ray units and radiation protection means used was collected using an occupational questionnaire. Based on the specific European data, changes in each parameter have been analysed over decades, while country-specific data analysis has allowed us to dete…
Retrograde transport of sodium selenite and intracellular injection of micro-ruby: a combined method to describe the morphology of zinc-rich neurones.
2003
Abstract Zinc is found in synaptic vesicles in a large number of glutamatergic systems. Its involvement in neurotransmission and neurological disorders has been suggested. There are methods for tracing these circuits, but they do not fill the dendritic tree. In this study, extracellular selenite injections in vivo were combined with intracellular injection of fluorochromes in fixed tissue to reveal the morphology of these zinc-rich neurones. Intraperitoneal and intracerebral injections of sodium selenite alone or intracerebral injections of selenite combined with bisbenzimide were made in the visual cortex of the rat in order to locate the somata of zinc-rich neurones. After 24 h of retrogr…
Individual repeatability in timing and spatial flexibility of migration routes of trans-Saharan migratory raptors
2015
Satellite-tracking technology has allowed scientists to make a quantum leap in the field of migration ecology. Nowadays, the basic description of migratory routes of many species of birds has been reported. However, the investigation of bird migration at individual level (i.e. repeatability in migratory routes and timing) still remains seldom explored. Here, we investigated repeated migratory trips of a trans-Saharan endangered migratory raptor, the Egyptian Vulture Neophron percnopterus, tracked by GPS satellite telemetry. We compared between- and within-individual variation in migratory routes and timing in order to assess the degree of repeatability (or conversely, the flexibility) in mi…
The rewarding effects of ethanol are modulated by binge eating of a high-fat diet during adolescence
2017
Abstract Binge-eating is considered a specific form of overeating characterized by intermittent and high caloric food intake in a short period of time. Epidemiologic studies support a positive relation between the ingestion of fat and ethanol (EtOH), specifically among adolescent subjects. The aim of this work was to clarify the role of the compulsive, limited and intermittent intake of a high-fat food during adolescence on the rewarding effects of EtOH. After binge-eating for 2 h, three days a week from postnatal day (PND) 29, the reinforcing effects of EtOH were tested with EtOH self-administration (SA), conditioned place preference (CPP) and ethanol locomotor sensitization procedures in …
Self-configuring multipath intra-mesh infrastructure QoS based routing
2016
International audience; Multi-path routing concept was largely exploited in wireless networks to provide benefits such as fault tolerance, load balancing, performance improvement in terms of latency, etc. In this paper, we propose a multi-path routing based protocol named MP-IMRR (Multi-path Intra-Mesh infrastructure Routing protocol) to improve our previously defined QoS based routing protocol for wireless mesh networks (i.e. IMRR). MP-IMRR is defined in order to achieve better reactivity and faster recovery from eventual route failures than the IMRR protocol by adopting the backup routes concept. Besides, given the complexity increase while considering network management systems, we adopt…
Catumaxomab: a bispecific trifunctional antibody.
2009
The trifunctional bispecific monoclonal antibody catumaxomab has two binding specificities directed at epithelial cell adhesion molecule (EpCAM) and the T-cell antigen CD3. With its Fc-fragment, catumaxomab additionally binds accessory cells such as dendritic cells, macrophages and natural killer cells. The trifunctional approach thus leads to unrestricted but specific killing of epithelial tumor cells by major histocompatibility complex without the need for preactivation or external costimulation. The tumor-associated antigen EpCAM is strongly expressed in carcinomas of various origins including colon, rectum, ovarian, gastric, esophagus, lung, pancreas, breast and head and neck. Expressio…
Tematisko maršrutu izmantošana tūrisma attīstībā: Latgales piemērs
2021
Tematisko maršrutu izmantošanas popularitāte ir augusi visā pasaulē, taču šo maršrutu pētniecība atrodas tikai pašos pirmsākumos. Šī pētījuma mērķis ir izpētīt tematisko maršrutu izmantošanu ilgtspējīga tūrisma attīstībā, kā piemēru izmantojot Latgales reģionu, par kuru šādi pētījumi līdz šim nav veikti. Darba mērķis ir izpētīt teorētisko pamatojumu ilgtspējīga tūrisma attīstībai un tematiskajiem maršrutiem; veikt pašreizējā tūrisma pieprasījuma un piedāvājuma primāro un sekundāro datu analīzi; identificēt jomas, kuras ir nepieciešams uzlabot un ierosināt iespējamos risinājumus problēmām, kuras saistītas ar tematisko maršrutu izmantošanu tūrisma attīstībā Latgales reģionā.

Metodologies competencials en la formació literària de mestres: experiències didàctiques per fomentar el pensament reflexiu: Competence-based methodo…
2023
L’objectiu d’aquest article és descriure i analitzar alguns projectes d’educació literària realitzats durant els últims vuit anys en el marc de la formació de docents per tal de reflexionar sobre la importància de l’ús de metodologies actives i competencials per l’ensenyament de la literatura al context universitari. Aquests projectes conformen experiències didàctiques com ara tallers d’escriptura, rutes literàries i l’ús dels videojocs per al foment lector. Presentem un comentari qualitatiu dels resultats d’aprenentatge més significatius i de la valoració dels estudiants a partir de la tria de diverses mostres. Finalment, arribem a la conclusió que aquestes experiències promouen no només l…
