Nova metodologia d'aprenentatge autònom aplicada a una pràctica d'Enginyeria Química mitjançant tècniques de recerca-acció

2014

Un grup de professors del Departament d'Enginyeria Química i Ambiental de l'Escola Tècnica Superior d'Enginyeria de la Universitat de Sevilla ha realitzat un treball d'investigació-acció amb l’objectiu de millorares resultats docents en l'assignatura Experimentació en Enginyeria Química. El procés d'investigació-acció ha consistit en dissenyar una metodologia alternativa per a una de les pràctiques de l'assignatura, incorporant un exercici d'auto-aprenentatge que substitueixi la tradicional metodologia aplicada. L'objectiu de l'experiència docent pretén aconseguir una participació més activa de l'alumnat, millorant l'assimilació de conceptes i la capacitat per planejar el treball experiment…

Access to scientific information. A national survey of the Italian Society of Clinical Biochemistry and Laboratory Medicine (SIBioC).

2016

Abstract Background: Digital libraries are typically used for retrieving and accessing articles in academic journals and repositories. Previous studies have been published about the performance of various biomedical research platforms, but no information is available about access preferences. Methods: A six-question survey was designed by the Italian Society of Clinical Biochemistry and Laboratory Medicine (SIBioC) using the platform Google Drive, and made available for 1 month to the members of the society. The information about the survey was published on the website of SIBioC and also disseminated by two sequential newsletters. Results: Overall, 165 replies were collected throughout the …

One-pot, direct incorporation of [11C]CO2 into carbamates.

2009

Why beat about the bush? An operationally simple and mild reaction based on the direct fixation of (11)CO(2) with 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) has been developed for the synthesis of (11)C-labeled carbamates at 75 degrees C within 10 minutes in radiochemical yields above 70% (see scheme). This strategy should be immediately useful for the construction of new radiotracers for positron emission tomography and other applications.

Post-fotografia etnografica

È evidente come la nostra società tecnologica sia legata senza alcun dubbio alla diffusione delle immagini. Autori come Gottfried Boehm, John Mitchell, Hans Belting hanno indagato la natura dell'immagine ponendo le basi, negli anni Novanta, per l'idea di un pictorial turn, di una cultura totalmente dominata dalle immagini che è diventata adesso una possibilità tecnica reale su scala globale. Un nuovo statuto dell'immagine che si usa raccogliere sotto l'etichetta di iconic turner inserito nel più vasto campo visual culture studies. L'uso del termine cultura accanto a quello di visuale è indicativo dell'ampiezza del campo d'indagine che visual culture studies si prefiggono di ricercare: essi …

It is evident that our technological society is undoubtedly linked to the diffusion of images. Authors such as Gottfried Boehm John Mitchell Hans Belting investigated the nature of the image by laying the foundations in the 1990s for the idea of ​​a pictorial turn of a culture totally dominated by images that has now become a real technical possibility on global scale. A new statute of the image that is used to collect under the label of iconic turner inserted in the wider field of visual culture studies. The use of the term culture alongside that of visual is indicative of the breadth of the field of investigation that visual culture studies aim to seek: they do not want to limit themselves to ascertaining the predominance of the visual in contemporary society and an evaluation of its aesthetic component. but they want to proceed towards an anthropological research in which visual culture is analyzed as a particular lifestyle that expresses certain meanings and values ​​not only in art and high culture but also in institutions and daily behavior. We will try to apply this new paradigm to photographs: instead of asking ourselves what the images mean let's try to ask ourselves what they want.

Prospects for quarkonium studies at the high-luminosity LHC

2020

Prospects for quarkonium-production studies accessible during the upcoming high-luminosity phases of the CERN Large Hadron Collider operation after 2021 are reviewed. Current experimental and theoretical open issues in the field are assessed together with the potential for future studies in quarkonium-related physics. This will be possible through the exploitation of the huge data samples to be collected in proton-proton, proton-nucleus and nucleus-nucleus collisions, both in the collider and fixed-target modes. Such investigations include, among others, those of: (i) J/psi and Upsilon produced in association with other hard particles; (ii) chi(c,b) and eta(c,b) down to small transverse mom…

Spatial mismatch through local public employment agencies Answers from a French quasi-experiment Spatial Mismatch through Local Public Employment Age…

2015

Using the unanticipated creation of a new agency in the French region of Lyon as a quasi-natural experiment, we question whether distance to local public employment agencies (LPEAs) is a new channel for spatial mismatch. Contrary to past evidence based on aggregated data and consistently with the spatial mismatch literature, we find no evidence of a worker/agency spatial mismatch, which pleads for a resizing of the French LPEA network. However, echoing with the literature on the institutional determinants of the local public employment agencies' efficiency, we do find detrimental institutional transitory effects.

LES DISCRIMINATIONS A L'EMBAUCHE DANS LA SPHERE PUBLIQUE : EFFETS RESPECTIFS DE L'ADRESSE ET DE L'ORIGINE

2016

Cette étude évalue la discrimination dans l’accès à l’emploi dans trois professions présentes à la fois dans le secteur privé et dans la Fonction Publique. Deux dimensions sont examinées : l’effet de la réputation du lieu de résidence et l’effet de l’origine maghrébine. Elle est réalisée sur données expérimentales de testing réalisé dans trois professions en tension pour lesquelles la discrimination devrait a priori être très réduite : les responsables administratifs de catégorie A, les techniciens de maintenance de catégorie B et les aides soignantes de catégorie C. Pour chaque profession, nous avons construit 3 profils fictifs de candidats à l’emploi similaires en tout point à l’exception…

Higher Education Institutions Quality and Graduate Wages in Tunisia

2017

International audience; We estimate the effect of university characteristics on the return to higher education in Tunisia. We use a variety of administrative data from the Ministry of Higher Education and Research, the Ministry of Vocational Training and Employment and the National Social Security Fund. We consider econometric approaches based on multilevel modeling, which distinguishes more precisely between the effects of individual factors and institutional factors on earnings. Our findings confirm the relationship between the income and some university characteristics such as the number of permanent teachers, the selectivity of the higher learning institutions at the academic orientatio…
