A general theory of rock glacier creep based on in-situ and remote sensing observations

Cicoira, Alessandro ; Marcer, Marco ; Gärtner‐Roer, Isabelle ; Bodin, Xavier ; Arenson, Lukas U. ; Vieli, Andreas

In: Permafrost and Periglacial Processes, 2020, p. -

The ongoing acceleration in rock glacier velocities concurrent with increasing air temperatures, and the widespread onset of rock glacier destabilization have reinforced the interest in rock glacier dynamics and in its coupling to the climate system. Despite the increasing number of studies investigating this phenomenon, our knowledge of both the fundamental mechanisms controlling rock...

Leading Millennials : what motivates and retains a labeled generation ?

Sukariyeh, Jude ; Connerton, Timothy (Dir.)

Mémoire de bachelor : Haute école de gestion de Genève, 2020 ; TDIBM 80.

This research aims at understanding why are Millennials’ a labeled generation, what are their characteristics and how can Leaders motivate as well as retain them. To do so, theories and studies are explored to see to which extend theory confirms what is observed in practice. The literature review attempts to share a storyline with the readers. The research covers various topics, from the...

High-harmonic generation in spin-orbit coupled systems

Lysne, Markus ; Murakami, Yuta ; Schüler, Michael ; Werner, Philipp

In: Physical Review B, 2020, vol. 102, no. 8, p. 081121

We study high-harmonic generation in two-dimensional electron systems with Rashba and Dresselhaus spin-orbit coupling and derive harmonic generation selection rules with the help of group theory. Based on the band structures of these minimal models and explicit simulations we reveal how the spin-orbit parameters control the cutoff energy in the high-harmonic spectrum. We also show that the...

Nanostructure generation during milk digestion in presence of a cell culture model simulating the small intestine

Hempt, Claudia ; Gontsarik, Mark ; Buerki-Thurnherr, Tina ; Hirsch, Cordula ; Salentinig, Stefan

In: Journal of Colloid and Interface Science, 2020, vol. 574, p. 430–440

Hypothesis: The development of advanced oral delivery systems for bioactive compounds requires the fundamental understanding of the digestion process within the gastrointestinal tract. Towards this goal, dynamic invitro digestion models, capable of characterising the molecular as well as colloidal aspects of food, together with their biological interactions with relevant invitro cell culture...

Skill Specificity of Upper-Secondary Training Occupations and the Gender Pay Gap = Berufliche Spezifität und Einkommensunterschiede zwischen Männern und Frauen

Miriam Grønning ; Irene Kriesi ; Stefan Sacchi

In: Kölner Zeitschrift für Soziologie und Sozialpsychologie, 2020, p. 1-25

Gender disparities in wages are still fairly large. On average, women earn less than men from the beginning of their careers. This article investigates whether young men and women with vocational education and training receive different returns for occupation-specific and general skills, a topic that has hitherto received little attention. Theoretically, we draw on a culturalist approach, as...

Competing Institutional Logics and Paradoxical Universalism : School-to-Work Transitions of Disabled Youth in Switzerland and the United States

Tschanz, Christoph ; Powell, Justin J. W.

In: Social inclusion, 2020, vol. 8, no. 1, p. 155-167

Disablement is a complex social phenomenon in contemporary societies, reflected in disability policies oriented towards contrasting paradigms. Fraught with ambivalence, disability raises dilemmas of classification and targeted supports. Paradoxical universalism emphasizes that to achieve universality requires recognizing individual dis/abilities and particular contextual conditions and barriers...

The impact of Social Media Influencer’s (SMI) on the buying decisions of Generation Y

Chowdhury, Ruhi Farzana ; Miller, Caroline (Dir.)

Mémoire de bachelor : Haute école de gestion de Genève, 2019 ; TDIBM 53.

This research aims to analyse how social media influencers on Instagram influence the purchasing decision of Millennial consumers in the luxury watch industry in Swiss Romandie. The first part of this project discusses different elements surrounding influencer marketing and Millennial’s online buying behaviour. The second part investigates Millennials’ presence on social media and their...

Optical rectification of ultrafast Yb lasers: pushing power and bandwidth of terahertz generation in GaP

Drs, Jakub ; Modsching, Norbert ; Paradis, Clément ; Kränkel, Christian ; Wittwer, Valentin Johannes ; Razskazovskaya, Olga ; Südmeyer, Thomas

In: Journal of the Optical Society of America B, 2019, vol. 36, no. 11, p. 3039-3045

We demonstrate broadband high-power terahertz (THz) generation at megahertz repetition rates by optical rectification in GaP driven by an ultrafast Yb-based thin-disk laser (TDL) oscillator. We investigate the influence of pulse duration in the range of 50–220 fs and thickness of the GaP crystal on the THz generation. Optimization of these parameters with respect to the broadest spectral...

Contesting categories: cross-border marriages from the perspectives of the state, spouses and researchers

Moret, Joëlle ; Andrikopoulos, Apostolos ; Dahinden, Janine

In: Journal of Ethnic and Migration Studies, 2019, p. 1-18

Marriages that involve the migration of at least one of the spouses challenge two intersecting facets of the politics of belonging: the making of the ‘good and legitimate citizens’ and the ‘acceptable family’. In Europe, cross-border marriages have been the target of increasing state controls, an issue of public concern and the object of scholarly research. The study of cross-border...

High-harmonic generation in quantum spin systems

Takayoshi, Shintaro ; Murakami, Yuta ; Werner, Philipp

In: Physical Review B, 2019, vol. 99, no. 18, p. 184303

We theoretically study the high-harmonic generation (HHG) in one-dimensional spin systems. While in electronic systems the driving by ac electric fields produces radiation from the dynamics of excited charges, we consider here the situation where spin systems excited by a magnetic field pulse generate radiation via a time- dependent magnetization. Specifically, we study the magnetic dipole...
