Neuroanatomy of the spinosaurid Irritator challengeri (Dinosauria: Theropoda) indicates potential adaptations for piscivory

Schade, Marco ; Rauhut, Oliver W. M. ; Evers, Serjoscha W.

In: Scientific Reports, 2020, vol. 10, no. 1, p. 9259

Spinosauridae, a theropod group characterized by elongated snouts, conical teeth, enlarged forelimbs, and often elongated neural spines, show evidence for semiaquatic adaptations and piscivory. It is currently debated if these animals represent terrestrial carnivores with adaptations for a piscivorous diet, or if they largely lived and foraged in aquatic habitats. The holotype of Irritator...

Online newspaper framing of non-communicable diseases : comparison of mainland China, Taiwan, Hong Kong and Macao

Chang, Angela ; Schulz, Peter J. ; Cheong, Angus Wenghin

In: International journal of environmental research and public health, 2020, vol. 17, no. 15, p. 15 p

As non-communicable diseases (NCDs) are now well recognized as the leading cause of mortality among adult populations worldwide, they are also increasingly the focus of media coverage. As such, the objective of this study is to describe the framing of NCDs in the coverage of newspapers, with the understanding that it says something about the society producing it. Automatic content analysis was ...

Apex predators decline after an influx of pastoralists in former Central African Republic hunting zones

Aebischer, Thierry ; Ibrahim, Tidjani ; Hickisch, Raffael ; Furrer, Roman D. ; Leuenberger, Christoph ; Wegmann, Daniel

In: Biological Conservation, 2020, vol. 241, p. 108326

Pastoralism is spreading in Central Africa, where many protected areas are under consideration to be opened for grazing, in particular hunting zones. Here we document the loss of biodiversity followed by an influx of transhumant pastoralism into previously uninhabited and virtually pristine habitat in the Central African Republic. Our track count and camera trap surveys of 2012, 2016 and...

The digital birth of an African city : the case of Douala

Pucciarelli, Marta ; Cantoni, Lorenzo (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2019 ; 2019COM003.

This dissertation focuses on the online communication and representation of a digital city in Africa: Douala, the largest city of the Republic of Cameroon. In particular, it explores the evolution of the web-based reproduction (Couclelis, 2004) of Douala, the largest city of the Republic of Cameroon, from a chronological, spatial and representational perspective, with the purpose of...

Randomizing growing networks with a time-respecting null model

Ren, Zhuo-Ming ; Mariani, Manuel Sebastian ; Zhang, Yi-Cheng ; Medo, Matú?

In: Physical Review E, 2018, vol. 97, no. 5, p. 052311

Complex networks are often used to represent systems that are not static but grow with time: People make new friendships, new papers are published and refer to the existing ones, and so forth. To assess the statistical significance of measurements made on such networks, we propose a randomization methodology—a time- respecting null model—that preserves both the network's degree sequence...

The oldest Archaeopteryx (Theropoda: Avialiae): a new specimen from the Kimmeridgian/Tithonian boundary of Schamhaupten, Bavaria

Rauhut​, Oliver W.M. ; Foth, Christian ; Tischlinger, Helmut

In: PeerJ, 2018, vol. 6, p. e4191

The iconic primeval bird Archaeopteryx was so far mainly known from the Altmühltal Formation (early Tithonian) of Bavaria, southern Germany, with one specimen having been found in the overlying Mörnsheim Formation. A new specimen (the 12th skeletal specimen) from the earliest Tithonian Painten Formation of Schamhaupten (Bavaria) represents the so far oldest representative of the genus. The...

Is China the new land of football ?

Sliwowski, Nicolas ; Depetris Chauvin, Nicolas (Dir.)

Mémoire de bachelor : Haute école de gestion de Genève, 2017 ; TD IBM 27.

In recent years, China has been in the spotlight for its determination to develop a relatively unexpected industry within its boundaries, football. The idea was introduced by the current President of the People’s Republic of China, Mr Xi Jinping, who intends to turn China into a top football nation. This is rather surprising considering that China has never been successful in football and has...
