Musée d'art et d'histoire (Genève)

Genève : Musée d'art et d'histoire, 2019

Tiré du site internet des Musées d'art et d'histoire (www.ville-geneve.ch/mah): "Cette exposition présente des œuvres exceptionnelles dont un grand nombre a été trouvé dans le Rhône. Jamais ou rarement prêtées par le Musée départemental Arles antique, tel un bronze représentant un captif ou cet énigmatique buste en marbre attribué par ses découvreurs à Jules César, ces pièces...

A review of causal mediation analysis for assessing direct and indirect treatment effects

Huber, Martin

(Working Papers SES ; 500)

Mediation analysis aims at evaluating the causal mechanisms through which a treatment or intervention affects an outcome of interest. The goal is to disentangle the total treatment effect into an indirect effect operating through one or several observed intermediate variables, the so-called mediators, as well as a direct effect reflecting any impact not captured by the observed mediator(s)....

The effects of anti-corruption videos on attitudes towards corruption in a Ukrainian online survey

Denisova-Schmidt, Elena ; Huber, Martin ; Prytula, Yaroslav

(Working Papers SES ; 499)

This paper presents the outcomes of an anti-corruption educational intervention among Ukrainian students based on an online experiment. More than 3,000 survey participants were randomly assigned to one of three different videos on corruption and its consequences (treatment groups) or a video on higher education (control group). The data suggest a high level of academic dishonesty and...

Emotional Inertia and Interpersonal Adaptation in Intimate Relationships

Luginbühl, Tamara ; Schöbi, Dominik (Dir.)

Thèse de doctorat : Université de Fribourg, 2018.

Emotions are not static but fluctuate over time as a function of contextual changes (Kuppens, Allen, & Sheeber, 2010). This temporal feature of emotions is considered in the concept of emotional inertia, which reflects the degree to which emotions are resistant to change over time (Kuppens et al., 2010). Several studies suggest an association between emotional inertia and psychological...

Direct and indirect treatment effects - causal chains and mediation analysis with instrumental variables

Fröhlich, Markus ; Huber, Martin

In: Journal of the Royal Statistical Society Series B, 2017, vol. 79, no. 5, p. 1645-1666

This paper discusses the nonparametric identification of causal direct and indirect effects of a binary treatment based on instrumental variables. We identify the indirect effect, which operates through a mediator (i.e. intermediate variable) that is situated on the causal path between the treatment and the outcome, as well as the unmediated direct effect of the treatment using distinct...

Direct and indirect effects of training vouchers for the unemployed

Huber, Martin ; Lechner, Michael ; Strittmatter, Anthony

In: Journal of the Royal Statistical Society Series A, 2018, vol. 181, no. 2, p. 441-463

This paper evaluates the effects of awarding vouchers for vocational training on the employment outcomes of unemployed voucher recipients in Germany, as well as the potential mechanism through which they operate. This study assesses the direct effects of voucher assignment net of actual redemption, which may be driven by preference shaping and learning about possible human capital investments...

A simple test for the ignorability of non-compliance in experiments

Huber, Martin

In: Economics letters, 2013, vol. 120, no. 3, p. 389-391

This paper proposes a simple method for testing whether non-compliance in experiments is ignorable, i.e., not jointly related to the treatment and the outcome. The approach consists of (i) regressing the outcome variable on a constant, the treatment, the assignment indicator, and the treatment/assignment interaction and (ii) testing whether the coefficients on the latter two variables are...

Dynamic Notch signalling regulates neural stem cell state progression in the Drosophila optic lobe

Contreras, Esteban G. ; Egger, Boris ; Gold, Katrina S. ; Brand, Andrea H.

In: Neural Development, 2018, vol. 13, no. 1, p. 25

Neural stem cells generate all of the neurons and glial cells in the central nervous system, both during development and in the adult to maintain homeostasis. In the Drosophila optic lobe, neuroepithelial cells progress through two transient progenitor states, PI and PII, before transforming into neuroblasts. Here we analyse the role of Notch signalling in the transition from neuroepithelial...

Constitutional absence of epithelial integrin α3 impacts the composition of the cellular microenvironment of ILNEB keratinocytes

He, Yinghong ; Thriene, Kerstin ; Boerries, Melanie ; Hausser, Ingrid ; Franzke, Claus-Werner ; Busch, Hauke ; Dengjel, Joern ; Has, Cristina

In: Matrix Biology, 2018, vol. 74, p. 62–76

Integrin α3β1, a major epidermal adhesion receptor is critical for organization of the basement membrane during development and wound healing. Integrin α3 deficiency leads to interstitial lung disease, nephrotic syndrome and epidermolysis bullosa (ILNEB), an autosomal recessive multiorgan disease characterized by basement membrane abnormalities in skin, lung and kidney. The pathogenetic...

Arp3 controls the podocyte architecture at the kidney filtration barrier

Schell, Christoph ; Sabass, Benedikt ; Helmstaedter, Martin ; Geist, Felix ; Abed, Ahmed ; Yasuda-Yamahara, Mako ; Sigle, August ; Maier, Jasmin I. ; Grahammer, Florian ; Siegerist, Florian ; Artelt, Nadine ; Endlich, Nicole ; Kerjaschki, Dontscho ; Arnold, Hans-Henning ; Dengjel, Jörn ; Rogg, Manuel ; Huber, Tobias B.

In: Developmental Cell, 2018, vol. 47, no. 6, p. 741-757.e8

Podocytes, highly specialized epithelial cells, build the outer part of the kidney filtration barrier and withstand high mechanical forces through a complex network of cellular protrusions. Here, we show that Arp2/3-dependent actin polymerization controls actomyosin contractility and focal adhesion maturation of podocyte protrusions and thereby regulates formation, maintenance, and capacity...
