French-speaking Swiss coffee consumer habits and coffee farmers’ living conditions

Dupont-Wuillemin, Fanny ; Shepherd, Mark (Dir.)

Mémoire de bachelor : Haute école de gestion de Genève, 2020 ; TDIBM 75.

The coffee industry and particularly coffee producers are facing difficult and challenging times. For years coffee prices have been falling and therefore producers have seen their revenue shrinking. This situation can be somewhat counterintuitive for French-speaking Swiss coffee consumers who have seen the selling price of their caffeine intake increase over time. However, the drop in coffee...

The last surviving Thalassochelydia — A new turtle cranium from the Early Cretaceous of the Purbeck Group (Dorset, UK)

Anquetin, Jérémy ; André, Charlotte

In: PaleorXiv, 2020, p. 7pa5c

Background. The mostly Berriasian (Early Cretaceous) Purbeck Group of southern England has produced a rich turtle fauna dominated by the freshwater paracryptodires Pleurosternon bullockii and Dorsetochelys typocardium. Each of these species is known by numerous relatively complete shells and by a single cranium. The two other turtles found in the Purbeck Group (Hylaeochelys belli, a species of...

Change detection of bare-ice albedo in the Swiss Alps

Naegeli, Kathrin ; Huss, Matthias ; Hoelzle, Martin

In: The Cryosphere, 2019, vol. 13, no. 1, p. 397–412

Albedo feedback is an important driver of glacier melt over bare-ice surfaces. Light- absorbing impurities strongly enhance glacier melt rates but their abundance, composition and variations in space and time are subject to considerable uncertainties and ongoing scientific debates. In this study, we assess the temporal evolution of shortwave broadband albedo derived from 15 end-of-summer...

Cyclostratigraphy of shallow-marine carbonates – limitations and opportunities

Strasser, André

In: Stratigraphy & Timescales, 2018, vol. 3, p. 151–187

The sedimentary record of ancient shallow-marine carbonate platforms commonly displays a stacking of different facies, which reflects repetitive changes of depositional environments through time. These changes can be induced by external factors such as cyclical changes in climate and/or sea level, but also by internal factors such as lateral migration of sediment bodies and/or changes in the...

La Formation du Grand Essert (Jura franco-suisse; Valanginien supérieur p.p. à Hauterivien supérieur basal) = The Grand Essert Formation (French-Swiss Jura Mountains; late Valanginian p.p. to earliest late Hauterivian)

Strasser, André ; Clavel, Bernard ; Monteil, Eric ; Charollais, Jean ; Piuz, André ; Mastransgelo, Bruno

In: Archives des Sciences, 2018, vol. 70, p. 205-282

Le terme de Formation du Grand Essert a été proposé en 2016 pour remplacer ceux de « Marnes d’Hauterive » auct. et « Pierre jaune de Neuchâtel » auct. attribués à l’« Hauterivien » auct. dans le Jura franco-suisse. L’objet de cette note est, dans un premier temps, de décrire et d’interpréter la lithologie de la coupe-type représentative de cette nouvelle formation,...
