Exploring the experiences of instructors teaching massive open online courses in tourism and hospitality : a mixed methods approach

Lin, Jingjing ; Cantoni, Lorenzo (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018COM001.

Massive Open Online Courses (MOOCs) have existed as a disruptive educational phenomenon for nine years. Grounded in the roots of distance education, open education, Open Educational Resources, and OpenCourseWare, MOOCs have now survived various critics and have continued growing globally. Reports about MOOCs in both the press and scholarly publications began to grow significantly in 2013...

Interaction-aware development environments : recording, mining, and leveraging IDE interactions to analyze and support the development flow

Minelli, Roberto ; Lanza, Michele (Dir.) ; Mocci, Andrea (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2017 ; 2017INFO013.

Nowadays, software development is largely carried out using Integrated Development Environments, or IDEs. An IDE is a collection of tools and facilities to support the most diverse software engineering activities, such as writing code, debugging, and program understanding. The fact that they are integrated enables developers to find all the tools needed for the development in the same place....

Code offloading in opportunistic computing

Ferrari, Alan ; Gambardella, Luca Maria (Dir.) ; Giordano, Silvia (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2017 ; 2017INFO014.

With the advent of cloud computing, applications are no longer tied to a single device, but they can be migrated to a high-performance machine located in a distant data center. The key advantage is the enhancement of performance and consequently, the users experience. This activity is commonly referred computational offloading and it has been strenuously investigated in the past years. The...

Malware detection at runtime for resource-constrained mobile devices : data-driven approach

Milošević, Jelena ; Malek, Miroslaw (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2017 ; 2017INFO012.

The number of smart and connected mobile devices is increasing, bringing enormous possibilities to users in various domains and transforming everything that we get in touch with into smart. Thus, we have smart watches, smart phones, smart homes, and finally even smart cities. Increased smartness of mobile devices means that they contain more valuable information about their users, more decision...

Evolution of a local population of a multiple-strain pathogen in its vector

Durand, Jonas ; Voordouw, Maarten (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2016.

Mixed-strain infections are the rule rather than the exception in most infectious diseases, and have important implication for the ecology and evolution of pathogens. The presence of multiple strains results in competitive interactions that can have a strong impact on the population structure of the pathogen. In vector-borne diseases, most of the research on competition between pathogen strains...

Kooperation von Schule und Familie aus Sicht der Eltern von Kindern mit Lese-Rechtschreib-Schwierigkeiten : Eine qualitative Untersuchung der elterlichen Perspektive auf die Zusammenarbeit von Fachpersonen der Primarschule und Eltern, deren Kinder von Lese-Rechtschreib-Schwierigkeiten (LRS) betroffen sind

Kern, Maja ; Stamm, Margrit (Dir.)

Thèse de doctorat : Université de Fribourg, 2017.

Die Zusammenarbeit von Schule und Familie hat in der heutigen Bildungslandschaft einen hohen Stellenwert. Weil Bildung und Erziehung im Bereich der geteilten Verantwortung von Schule und Elternhaus liegen, die Aufgabenteilung aber nicht immer klar geregelt ist und zuweilen unterschiedliche Ansichten aufeinander prallen, birgt die Kooperation grosses Konfliktpotential. Bei Lernschwierigkeiten des...

The novel chloroplast outer membrane kinase KOC1 is a required component of the plastid protein import machinery

Zufferey-Arias, Mónica Alexandra ; Kessler, Felix (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2017.

The chloroplast constitutes the site of photosynthesis and is an essential organelle in plant cells. An endosymbiotic event was at the origin of the chloroplast, an ancestral eukaryotic cell engulfing a photosynthetic cyanobacterium. During evolution, the majority of ancestral chloroplast genes were lost or transferred to the nucleus. The protein products of the successfully transferred genes are...

Uncertainty propagation and global sensitivity analysis in multi-layered hydrogeological models of flow and lifetime expectancy

Deman, Grégory ; Perrochet, Pierre (Dir.) ; Kerrou, Jaouher (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2015.

The main focus of this thesis is the uncertainty propagation (UP) and global sensitivity analysis (GSA) in complex hydrogeological numerical models. Various methods are presented with applications on numerical models for the groundwater flow and mean lifetime expectancy (MLE) in the scope of Andra's (French National Radioactive Waste Management Agency) project for the geological disposal of...

Des formes d'humus au bois mort et du bois mort aux formes d'humus : contribution à l'étude des formes d'humus et des communautés lombriciennes en zone forestière subalpine, avec une emphase particulière sur le bois mort

Tatti, Dylan ; Gobat, Jean-Michel (Dir.) ; Le Bayon, Claire (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2016.

This thesis is part of a larger research, the DecAlp project. This latter is conduct in the Italian Alps (Trentino, I) and involved numerous researchers with the shared goal of elaborating a model for wood decomposition and its incorporation into the soil. This thesis focuses mainly on the humus forms. They occupy a key role in the DecAlp project as they allow linking the aerial and the...

The mate-seeking strategies of four braconid parasitoids (Hymenoptera: Braconidae)

Xu, Hao ; Turlings, Ted (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2017.

Parasitic wasps are widely used as biological control agents. To optimize their applications in agriculture, we need to understand how they locate hosts and mate. Parasitic wasps have about 50,000 described species, but less than 30 species have so far been tested in terms of their use of pheromones. In this thesis, I used a combination of bioassays, chemical analyses, and electrophysiological...
