Are people with aphasia (pwa) involved in the creation of quality of life and aphasia impact-related questionnaires? A scoping review

Charalambous, Marina ; Kambanaros, Maria ; Annoni, Jean-Marie

In: Brain Sciences, 2020, vol. 10, no. 10, p. 688

Background: Quality of Life (QoL) questionnaires are used to describe the impact of aphasia on stroke survivors’ life. People with aphasia (PWA) are traditionally excluded from research, potentially leading to a mismatch between the factors chosen in the tools and the realistic needs of PWA. The purpose of this review was to determine the direct involvement of PWA in the creation of QoL and...

Transnational machine learning with screens for flagging bid-rigging cartels

Huber, Martin ; Imhof, David ; Ishii, Rieko

(Working Papers SES ; 519)

We investigate the transnational transferability of statistical screening methods originally developed using Swiss data for detecting bid-rigging cartels in Japan. We find that combining screens for the distribution of bids in tenders with machine learning to classify collusive vs. competitive tenders entails a correct classification rate of 88% to 93% when training and testing the method...

Empirical Essays on Preference Formation and Economic Decision Making

Tyahlo, Svitlana ; Eichenberger, Reiner (Dir.)

Thèse de doctorat : Université de Fribourg, 2020.

This dissertation consists of four independent papers on economically relevant topics that cap- tured my attention because of personal background and professional experiences, such as coming from Ukraine, being an educated woman, living in a bilingual Swiss region and observing people delaying their work. Throughout my papers, I empirically analyze the determinants of individual attitudes ...

Lentiviral-mediated up-regulation of let-7d microRNA decreases alcohol intake through down-regulating the dopamine D3 receptor

Bahi, Amine ; Dreyer, Jean-Luc

In: European Neuropsychopharmacology, 2020, vol. 37, p. 70–81

Recent studies have shown that Lethal-7 (let-7) microRNA (miRNA) is involved in a wide range of psychiatric disorders such as anxiety, depression, schizophrenia, and cocaine addiction. However, the exact role of let-7d miRNA in regulating ethanol intake and preference remains to be elucidated. The aim of the present study was to clarify the role of accumbal let-7d in controlling...

Development of stereo vision in young infants

Röthlisberger, Martina ; Frick, Andrea

In: Infancy, 2020, p. 1-16

In this study, infants’ visual processing of depth-inducing stimuli was tested using a new method suitable for experimental settings. Stereograms of the Lang-Stereopad® were presented in a timed preferential-looking paradigm to determine infants’ preference for a stereogram as compared to a stimulus not inducing an impression of depth. A total of 80 infants were tested at 7 months of age; of...

Institutional setting and networks effect on international trade : Three essays on international trade

Arioldi, Davide ; Maggi, Rico (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018ECO016.

This thesis explores the role of different measures of proximity on some topics related to international trade. We focus on how institutional setting (institutional proximity) and network structure (cognitive and social proximity) influence the geography of international trade. In the first chapter, we extend the results of Rose and Spiegel (2011) and the findings by Bista (2017) proposing a...

Household resources and individual strategies

Deschênes, Sarah ; Dumas, Christelle ; Lambert, Sylvie

(Working Papers SES ; 517)

The question of diverging interests and preferences within couples over the use of household resources and the consequences of these conflictual views has been present for a long time in the development literature, albeit in a somewhat scattered way. This paper selectively reviews the abundant literature that offers insights into the intrahousehold decision-making process, the strategies put...

Essays in household finance and monetary policy transmission

Gianinazzi, Virginia ; Plazzi, Alberto (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2020ECO005.

This thesis consists of three chapters that contribute to two fundamental questions in finance: how households make financial decisions and how market prices react to uninformative demand shocks. The first chapter investigates how household respond to mortgage refinancing incentives. A well-documented finding in household finance is that many borrowers miss out on substantial savings by...

The Dynamic Reorganization of Cortical Network Interactions during Visual Selective Attention

Pagnotta, Mattia ; Plomp, Gijs (Dir.)

Thèse de doctorat : Université de Fribourg, 2020.

Visual selective attention prioritizes the processing of behaviorally relevant over irrelevant information, to optimize the use of limited cognitive resources in the brain. These selective mechanisms preferentially route relevant neuronal representations through a network of distributed brain regions. Previous studies suggested that selective information routing in the attention network may...

Gender differences in wage expectations

Fernandes, Ana ; Huber, Martin ; Vaccaro, Giannina

(Working Papers SES ; 516)

Using a survey on wage expectations among students at two Swiss institutions of higher education, we examine the wage expectations of our respondents along two main lines. First, we investigate the rationality of wage expectations by comparing average expected wages from our sample with those of similar graduates; we further examine how our respondents revise their expectations when provided...
