The challenge that we have taken up as a multidisciplinary group of scholars interested in strengthening the position of interview data in the Digital Humanities realm, is to encourage scholars to use technology to handle their interview data, and to engage with practices of fellow scholars in adjacent disciplines. Coming from distinctive disciplines such as oral history, ethnography, sociology, media studies, speech technology, computational linguistics, socio-linguistics, phonetics, human media interaction, information - and computer science, we all have a different interest in human expression, the modalities in which it is conveyed - written text, speech, gestures, sounds - and the ways in which it can be structured in order to be studied. Technology is now able to facilitate processes that used to be cumbersome, such as transcription and its alignment with audio, but it also offers ways of venturing into other disciplines or teaming up with a scholar from a different discipline to compare each others analytical approaches and results.

This thesis studies the nonequilibrium properties of quantum dots with regard to electrical conduction as well as thermodynamics. The work documented here shows how these properties behave under the influence of time-dependent drive protocols, pursuing two main lines of inquiry. The first concerns the interplay between nanomechanics and drive: In nanomechanical systems with strong coupling between the charge and vibrational sectors, conductance is strongly suppressed, an effect known as Franck-Condon blockade. Using a model Hamiltonian for a molecular quantum dot coupled to a pair of leads, it is shown here that this blockade can be exponentially lifted by resonantly driving the dot. Moreover, a multi-drive protocol is proposed for such a system to facilitate charge pumping that enjoys the same exponential amplification. The second line of inquiry moves beyond charge transport, examining the thermodynamics of a driven quantum dot coupled to a lead. Taking a Green's function approach, it is found that the laws of thermodynamics can be formulated for arbitrary dot-lead coupling strength in the presence of dot and coupling drive, as long as the drive protocol only exhibits mild non-adiabaticity. Finally, the effects of initial states are studied in this situation, proving that the integrated work production in the long-time limit conforms to the second law of thermodynamics for a wide class of initial states and arbitrary drive and coupling strength.

During the last two decades, the wine auction market experienced non-monotonic dynamics and provided abnormal returns. When fine wine prices started to rise in the mid-1980s, wine investing transcended from a pastime into a serious investment transforming wine into a widespread investment activity. As an alternative asset, fine wine attracts increased attention among individual and institutional investors in recent years, particularly during the financial crisis due to its diversification potential. Economists also began evaluating wine as a new alternative asset class. In this thesis, we review the wine auction markets, study the price dynamics, and answer some fundamental questions. To build solid conclusions, we developed the largest French wine auction database encompassing the last 20 years. We summary our main contributions as follows. First, we review and explain the growth in recent global wine auction markets. Second, we construct price indices with hedonic regression models to observe market movements. Third, we investigate wine investment’s diversification potential. Wine in an optimal portfolio can improve the risk-return characteristics; however, the augmentation depends significantly on the market segmentation to which the investor applies it. Fourth, we analyze the wine price bubbles and collapses detection using a newly developed econometric approach. We elucidate strong evidence of two bubbles in the Bordeaux and Burgundy wine auction markets, whereas Rhône wine price behaved in a similar, but less significant, trend as Bordeaux and Burgundy wine markets. Finally, we examine the price determinants with a particular focus on the expert effect on this experienced good. We illuminate expert influence remains economically and statistically significant throughout the sample period. Using event study methodology, we disentangle the expert effect from other price variations and assert the market significantly reflects expert’s big re-ratings in the short term, yet the effect diminishes over time. However, this re-rating effect holds insignificant for modest changes. [less ▲]

Seit 2016 widmet sich ein Forschungsprojekt der Universität, in Zusammenarbeit mit der Stadt Luxemburg, der Erstellung eines historischen Atlas. Dieser wird die städtische Entwicklung seit Beginn des 19. Jahrhunderts in Form von digitalen und interaktiven Karten im Internet darstellen. Fünf Zeitschnitte sind vorgesehen, um die tiefgreifenden Wandlungsprozesse Luxemburgs zu analysieren und zugleich auch spannend und anschaulich zu präsentieren: Von der Festungsstadt, die das militärische Korsett erst nach 1867 ablegen konnte, über eine moderne europäischen Hauptstadt des frühen 20. Jahrhunderts bis hin zu einem der Hauptverwaltungssitze der EU und einem internationalen Finanzzentrum. Ein Jahr vor der offiziellen Veröffentlichung des Atlas werden erste Ergebnisse präsentiert. Dies ermöglicht einen Einblick in die historische Forschungsarbeit sowie in die digitale Aufbereitung alter Karten für die Publikation im Internet. [less ▲]

Urban green space (UGS) has many environmental and social benefits. UGS provision and access are increasingly considered in urban policies and must rely on data and indicators that can capture variations in the distribution of UGS within cities. There is no consensus about how UGS, and their provision and access, must be defined from different land use data types. Here we identify four spatial dimensions of UGS and critically examine how different data sources affect these dimensions and our understanding of their variation within a city region (Brussels). We compare UGS indicators measured from an imagery source (NDVI from Landsat), an official cadastre-based map, and the voluntary geographical information provided by OpenStreetMap (OSM). We compare aggregate values of provision and access to UGS as well as their spatial distribution along a centrality gradient and at neighbourhood scale. We find that there are strong differences in the value of indicators when using the different datasets, especially due to their ability to capture private and public green space. However we find that the interpretation of intra-urban spatial variations is not affected by changes in data source. Centrality in particular is a strong determinant of the relative values of UGS availability, fragmentation and accessibility, irrespective of datasets. [less ▲]

The deluge of Android apps from third-party developers calls for sophisticated security testing and analysis techniques to inspect suspicious apps without accessing their source code. Code coverage is an important metric used in these techniques to evaluate their effectiveness, and even as a fitness function to help achieving better results in evolutionary and fuzzy approaches. Yet, so far there are no reliable tools for measuring fine-grained bytecode coverage of Android apps. In this work we present ACVTool that instruments Android apps and measures the smali code coverage at the level of classes, methods, and instructions.

Learners throughout different educational levels and study domains use a significant amount of time to consult learning material. In addition to the resources given by their teachers, further information might be required by the learner. However, leaving the study context to search for related material may lead to distraction or even abandonment of the learning task. Furthermore, traditional learning resources do not foster active learning. In this paper, we present SoLeMiO, a plugin for Office applications, which identifies key concepts in a document and thereby integrates related, heterogeneous resources from an open corpus. We employ concept recognition tools to determine concepts from different domains. Thereupon, resources from different repositories are suggested to the learner and can be consulted from within the current document. Aside from traditional learning resources, active learning is fostered through gamification activities. We showcase the applicability of our approach in multiple disciplines with concrete examples.

Malignant melanoma is a highly aggressive form of skin cancer responsible for the majority of skin cancer-related deaths. Recent insight into the heterogeneous nature of melanoma suggests more personalised treatments may be necessary to overcome drug resistance and improve patient care. To this end, reliable molecular signatures that can accurately predict treatment responsiveness need to be identified. In this study, we applied multiplex phosphoproteomic profiling across a panel of 24 melanoma cell lines with different disease-relevant mutations, to predict responsiveness to MEK inhibitor trametinib. Supported by multivariate statistical analysis and multidimensional pattern recognition algorithms, the responsiveness of individual cell lines to trametinib could be predicted with high accuracy (83% correct predictions), independent of mutation status. We also successfully employed this approach to case specifically predict whether individual melanoma cell lines could be sensitised to trametinib. Our predictions identified that combining MEK inhibition with selective targeting of c-JUN and/or FAK, using siRNA-based depletion or pharmacological inhibitors, sensitised resistant cell lines and significantly enhanced treatment efficacy. Our study indicates that multiplex proteomic analyses coupled with pattern recognition approaches could assist in personalising trametinib-based treatment decisions in the future. [less ▲]

This thesis analyzes the status of tax circulars and tax rulings in domestic law. More precisely, by first studying the status of each of these administrative interpretative acts, I then investigate their enforceability before domestic courts and enquire to what extent unlawful circulars and contra legem rulings can be relied upon by virtue of the principle of legitimate expectations. After extracting a series of shortcomings in the protection of taxpayers who rely on such administrative interpretative acts, I then, articulate from a normative perspective, what I claim to be the appropriate level of protection for contra legem circulars and advance decisions in the Luxembourg legal order.
