Institutional effects on nurses’ working conditions: a multi-group comparison of public and private non-profit and for-profit healthcare employers in Switzerland

Aeschbacher, Remo ; Addor, Véronique

In: Human Resources for Health, 2018, vol. 16, no. 58, p. 1-10

Background: In response to the need for competitive recruitment of nurses resulting from the worldwide nursing shortage, employers need to attract and retain nurses by promoting their competitive strengths in their working conditions (WCS) and by addressing their competitive weaknesses. This study investigated workplace differences between public hospitals (PuHs), private for-profit hospitals...

Do Anti-Corruption Educational Campaigns Reach Students? : Evidence from Russia and Ukraine

Denisova-Schmidt, Elena ; Huber, Martin ; Leontyeva, Elvira

In: Educational studies. Moscow, 2016, no. 1, p. 61-83

The authors investigate the effect of anti-corruption educational materials — an informational folder with materials designed by Transparency International — on the willingness of students to participate in an anti-corruption campaign and their general judgment about corruption in two cities in Russia and Ukraine by conducting experiments. During a survey of 350 students in Khabarovsk,...

Regional differences in perceived corruption among Ukrainian firms

Denisova-Schmidt, Elena ; Huber , Martin

In: Eurasian geography and economics, 2014, vol. 55, no. 1, p. 10-36

This paper investigates regional differences in the perception of corruption and informal practices among Ukrainian firms. Using two different data sets from Ukraine, we show that perceived corruption differs significantly across regions, even when taking into account the size, industry, workforce composition, and other characteristics of the firms based on propensity score matching. In...

Radius matching on the propensity score with bias adjustment : tuning parameters and finite sample behaviour

Huber, Martin ; Lechner, Michael ; Steinmayr, Andreas

In: Empirical economics, 2015, vol. 49, no. 1, p. 1-31

Using a simulation design that is based on empirical data, a recent study by Huber et al. (J Econom 175:1–21, 2013) finds that distance-weighted radius matching with bias adjustment as proposed in Lechneret et al. (J Eur Econ Assoc 9:742–784, 2011) is competitive among a broad range of propensity score-based estimators used to correct for mean differences due to observable covariates. In...

Persistent hippocampal neural firing and hippocampal-cortical coupling predict verbal working memory load

Boran, Ece ; Fedele, Tommaso ; Klaver, Peter ; Hilfiker, Peter ; Stieglitz, Lennart ; Grunwald, Thomas ; Sarnthein, Johannes

In: Science Advances, 2019, vol. 5, no. 3, p. 1-14

The maintenance of items in working memory relies on persistent neural activity in a widespread network of brain areas. To investigate the influence of load on working memory, we asked human subjects to maintain sets of letters in memory while we recorded single neurons and intracranial encephalography (EEG) in the medial temporal lobe and scalp EEG. Along the periods of a trial, hippocampal...

Short-Term Effects of a Multidimensional Stress Prevention Program on Quality of Life, Well-Being and Psychological Resources : A Randomized Controlled Trial

Recabarren, Romina Evelyn ; Gaillard, Claudie ; Guillod, Matthias ; Martin-Soelch, Chantal

In: Frontiers in Psychiatry, 2019, vol. 10, no. 88, p. 1-15

It is well-documented that university students have an increased risk in developing psychological problems because they face multiple stressors. Cognitive, behavioral, and mindfulness-based stress prevention programs were shown to reduce symptoms of anxiety, depression, and perceived stress in university students. However, little is known of their effect on resource activation. Additionally, most...

Monoclonal IgG antibodies generated from joint-derived B cells of RA patients have a strong bias toward citrullinated autoantigen recognition

Amara, Khaled ; Steen, Johanna ; Murray, Fiona ; Morbach, Henner ; Fernandez-Rodriguez, Blanca M. ; Joshua, Vijay ; Engström, Marianne ; Snir, Omri ; Israelsson, Lena ; Catrina, Anca I. ; Wardemann, Hedda ; Corti, Davide ; Meffre, Eric ; Klareskog, Lars ; Malmström, Vivianne

In: The journal of experimental medicine, 2013, vol. 210, no. 3, p. 445-455

Antibodies targeting citrullinated proteins (ACPAs [anticitrullinated protein antibodies]) are commonly found in patients with rheumatoid arthritis (RA), strongly associate with distinct HLA-DR alleles, and predict a more aggressive disease course as compared with seronegative patients. Still, many features of these antibodies, including their site of production and the extent of MHC class...

Cxcl12 evolution – subfunctionalization of a ligand through altered interaction with the chemokine receptor

Boldajipour, Bijan ; Doitsidou, Maria ; Tarbashevich, Katsiaryna ; Laguri, Cedric ; Yu, Shuizi Rachel ; Ries, Jonas ; Dumstrei, Karin ; Thelen, Sylvia ; Dörries, Julia ; Messerschmidt, Esther-Maria ; Thelen, Marcus ; Schwille, Petra ; Brand, Michael ; Lortat-Jacob, Hugues ; Raz, Erez

In: Development, 2011, vol. 138, no. 14, p. 2909-2914

The active migration of primordial germ cells (PGCs) from their site of specification towards their target is a valuable model for investigating directed cell migration within the complex environment of the developing embryo. In several vertebrates, PGC migration is guided by Cxcl12, a member of the chemokine superfamily. Interestingly, two distinct Cxcl12 paralogs are expressed in zebrafish...

From Asia to Europe : evaluation of parasitoids for the biological control of the invasive fruit pest "Drosophila suzukii"

Girod, Pierre ; Turlings, Ted (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2018.

Agricultural processes are constantly improved to improve crop yields. However, 40% of crop productions are currently lost to pests each year. Insect pests are one of the main factors of these losses and their management is one of the top priorities that researchers are facing worldwide. An important part of these losses are caused by pest with alien origins. Globalization and climate change...

Intracortical inhibition increases during postural task execution in response to balance training

Mouthon, Audrey ; Taube, Wolfgang

In: Neuroscience, 2019, vol. 401, p. 35–42

Intracortical inhibitory modulation seems crucial for an intact motor control and motor learning. However, the influence of long(er) term training on short-interval intracortical inhibition (SICI) is scarcely investigated. With respect to balance, it was previously shown that with increasing postural task difficulty, SICI decreased but the effect of balance training (BT) is unknown. The...
