Self-avoiding walk on $\mathbb{Z}^{2}$ with Yang–Baxter weights: Universality of critical fugacity and 2-point function

Glazman, Alexander ; Manolescu, Ioan

In: Annales de l’Institut Henri Poincaré, Probabilités et Statistiques, 2020, vol. 56, no. 4, p. 2281–2300

We consider a self-avoiding walk model (SAW) on the faces of the square lattice Z2. This walk can traverse the same face twice, but crosses any edge at most once. The weight of a walk is a product of local weights: each square visited by the walk yields a weight that depends on the way the walk passes through it. The local weights are parametrised by angles θ∈[π3,2π3] and satisfy the...

Neural Machine Reading for Domain-Specific Text Resources

Arnold, Sebastian ; Cudré-Mauroux, Philippe (Dir.)

Thèse de doctorat : Université de Fribourg, 2020.

The vision of Machine Reading is to automatically understand written text and transform the contained information into machine-readable representations. This thesis approaches this challenge in particular in the context of commercial organizations. Here, an abundance of domain-specific knowledge is frequently stored in unstructured text resources. Existing methods often fail in this scenario,...

Biomechanical agreement between different imitation jumps and hill jumps in ski jumping

Ketterer, Jakob ; Gollhofer, Albert ; Lauber, Benedikt

In: Scandinavian Journal of Medicine & Science in Sports, 2020, p. sms.13834

Even though the take‐off in ski jumping is decisive, athletes only have a very limited number of training trials on the actual ski jump to practice under real ski jump conditions. Hence, various imitation jumps aiming to mimic the hill jump are performed during daily training. These imitation jumps should therefore mimic the kinematic pattern of hill jumps appropriately. This study aimed to...

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...

„Und bist du nicht willig, so brauch ich Gewalt“ : Der Trainingsraum: Empirische Befunde, theoretische Perspektiven, pädagogische Alternativen

Hövel, Dennis Christian ; Zimmermann, David ; Meyer, Barbara ; Gingelmaier, Stephan

In: Sonderpädagogische Förderung heute, 2020, vol. 65, p. 1-15

Der vorliegende Beitrag thematisiert das Konzept des Trainingsraums für den schulischen Umgang mit Unterrichtsstörungen. Nach einer Einführung in die Maßnahme werden in einem Review des aktuellen Forschungsstands die empirischen Befunde überblicksartig dargestellt. Anschließend wird das Programm mit Blick auf ethische und theoretische Grundlagen der (Sonder-)Pädagogik diskutiert und...

Who is included in VET, who not?

Scharnhorst, Ursula ; Kammermann, Marlise

In: Education + Training, 2020, vol. 62, no. 6, p. 645-658

Purpose The paper describes the Swiss Vocational Education and Training (VET) system, its crucial role and challenges with respect to the inclusion of vulnerable groups and investigates the effectiveness of the efforts undertaken to promote inclusion in VET so far. Design/methodology/approach Empirical research focusing on various indicators of inclusion (national monitoring data and own studies)...

Voronoi-like diagrams : towards linear-time algorithms for tree-like abstract Voronoi diagrams

Junginger, Kolja ; Papadopoulou, Evanthia (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2020INFO013.

Computational Geometry is a subfield of Algorithm Design and Analysis with a focus on the design and analysis of algorithms related to discrete geometric objects. The Voronoi diagram is one of the most important structures in Computational Geometry providing proximity information, which is applicable to many different fields of science. For a given set of points in the plane – called sites...

Unsupervised and Parameter-Free Clustering of Large Graphs for Knowledge Exploration and Recommendation

Lutov, Artem ; Cudré-Mauroux, Philippe (Dir.)

Thèse de doctorat : Université de Fribourg, 2020 ; no. 2192.

We live in an Information Age, facing a rapid increase in the amount of information that is exchanged. This permanently growing amount of data makes the ability to store, analyze, and act upon information a primary concern (in addition to the obvious privacy, legal and ethical issues that are related), raising the question: “How can one consume Big Data and transformit into actionable...

International students in Switzerland : trajectories, stay rates, and intentions for post-graduate mobility

Lombard, Annique ; Piguet, Etienne (Dir.) ; Riaño, Yvonne (Codir.) ; van Mol, Christof (Codir.) ; Wiers-Jenssen, Jannecke (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2019.

Increased international student mobility (ISM) has become one of the salient features of contemporary global migration. In the context of growing global mobility and the globalization of higher education, international student migration to Switzerland is changing significantly in both extent and character. Due to the importance of international students in current migration flows, their mobility...

The elasticity of voter turnout: Investing 85 cents per voter to increase voter turnout by 4 percent

Schelker, Mark ; Schneiter, Marco

In: Electoral Studies, 2017, vol. 49, p. 65-74

In the aftermath of elections or ballots, the legitimacy of the result is regularly debated if voter turnout was considered to be low. Hence, discussions about legal reforms to increase turnout are common in most democracies. We analyze the impact of a very small change in voting costs on voter turnout. Some municipalities in the Swiss Canton of Bern reduced voting costs by prepaying the postage...
