Un projet de médiation numérique en bibliothèque : de la réflexion stratégique au choix de l'outil

Frech, Gabrielle ; Furer-Benedetti, Michèle (Dir.) ; Yoakim-Pasquier,Karine (Codir.)

Mémoire de Certificate of Advanced Studies (CAS) : Université de Fribourg, 2015.

Promouvoir les activités de sa bibliothèque, améliorer la mise en valeur de certaines ressources, développer une communication virtuelle avec ses usagers, sont autant de réflexions qui motivent les bibliothèques à penser à des actions de médiation numérique. L'objectif de ce travail est d'offrir au SEM Documentation de Genève, ainsi qu'aux bibliothèques intéressées par le sujet, des...

Notch1 hallmarks fibrillary depositions in sporadic Alzheimer’s disease

Brai, Emanuele ; Raio, Noemi Alina ; Alberi, Lavinia

In: Acta Neuropathologica Communications, 2016, vol. 4, p. 64

Background: Notch1 signaling is a cellular cascade with a fundamental role from brain development to adult brain function. Reduction in Notch1 affects synaptic plasticity, memory and olfaction. On the other hand, Notch1 overactivation after brain injury is detrimental for neuronal survival. Some familial Alzheimer’s disease (FAD) mutations in Presenilins can affect Notch1...

Age of second-language acquisition: Critical periods and social concerns

Birdsong, David ; Vanhove, Jan

In: Bilingualism across the lifespan: Factors moderating language proficiency, 2016, p. 163-182

A classic topic in research on bilingualism across the lifespan is the relationship between the age at which learners start to acquire a second language (L2) and their ultimate level of proficiency in that language. Learning of an L2 that begins in infancy is typically associated with fluent speech, effortless language processing, and native accent. In contrast, late L2 learners tend to diverge...

Settori di contatto tra romancio grigionese e italiano : il lessico alimentare = Domains of contact between Romansh of Grisons and Italian: the vocabulary of nutrition

Grünert, Matthias

In: Ad limina Alpium. VI Colloquium Retoromanistich. Cormons, dai 2 ai 4 di Otubar dal 2014, 2016, p. 315-339

Il contributo presenta, nell’ambito del lessico alimentare, il legame particolare che intercorre tra la parte romancia dei Grigioni e lo spazio italofono vicino, comprendente l’Alta Italia e la Svizzera italiana. Dopo un breve tour d’horizon degli italianismi del settore scelto, si trattano piu in dettaglio i prestiti dalle varieta italiane settentrionali a livello fonetico, morfologico...

How war affects political attitudes: evidence from eastern Ukraine

Huber, Martin ; Tyahlo, Svitlana

(Working Papers SES ; 472)

This study empirically evaluates the impact of the war in eastern Ukraine on the political attitudes and sentiments towards Ukraine and Russia among the population living close to the war zone on the territory controlled by the Ukrainian government. Exploiting unique survey data that were collected in early 2013 (13 months before the outbreak of the conflict) and early 2015 (11 months after the...

On the use of interview data for the microsimulation of ideological conflicts : an analysis of the political cleavages of the European left

Müller, Georg P.

(Working Papers SES ; 471)

There is an increasing number of interview projects like the European Values Study (EVS) or the International Social Survey Programme (ISSP), which collect in many different countries internationally comparative interview data. Some of them even offer time series, which go back to the 1980ies. Unfortunately, these public datasets are generally not suitable for the analysis of political conflicts...

A wild bootstrap algorithm for propensity score matching estimators

Huber, Martin ; Camponovo, Lorenzo ; Bodory, Hugo ; Lechner, Michael

(Working Papers SES ; 470)

We introduce a wild bootstrap algorithm for the approximation of the sampling distribution of pair or one-to-many propensity score matching estimators. Unlike the conventional iid bootstrap, the proposed wild bootstrap approach does not construct bootstrap samples by randomly resampling from the observations with uniform weights. Instead, it fixes the covariates and constructs the bootstrap...

Fundamental measure theory for non-spherical hard particles: predicting liquid crystal properties from the particle shape

Wittmann, René ; Marechal, Matthieu ; Mecke, Klaus

In: Journal of Physics: Condensed Matter, 2016, vol. 28, no. 24, p. 244003

Density functional theory (DFT) for hard bodies provides a theoretical description of the effect of particle shape on inhomogeneous fluids. We present improvements of the DFT framework fundamental measure theory (FMT) for hard bodies and validate these improvements for hard spherocylinders. To keep the paper self-contained, we first discuss the recent advances in FMT for hard bodies that lead...

Electronic orders in multiorbital Hubbard models with lifted orbital degeneracy

Hoshino, Shintaro ; Werner, Philipp

In: Physical Review B, 2016, vol. 93, no. 15, p. 155161

We study the symmetry-broken phases in two- and three-orbital Hubbard models with lifted orbital degeneracy using dynamical mean-field theory. On the technical level, we explain how symmetry relations can be exploited to measure the four-point correlation functions needed for the calculation of the lattice susceptibilities. In the half-filled two- orbital model with crystal-field splitting, we...
