Evolution of a Field : Swiss Media and Communication Studies

Probst, Carole ; Buhmann, Alexander ; Ingenhoff, Diana ; Lepori, Benedetto

In: Studies in Communication Sciences, 2019, vol. 19, no. 1, p. 7-23

In this paper, we present the evolution of Swiss Media and Communication Studies over the last decade by summarizing the main results from a project funded by the Swiss University Conference (2008–2017). We give an overall picture of the growth in the field (in terms of student numbers, resources and activities), look at diversity in terms of topics (two clusters are identified and ...

The importance of assessing positive and beneficial impacts of alien species

Vimercati, Giovanni ; Kumschick, Sabrina ; Probert, Anna F. ; Volery, Lara ; Bacher, Sven

In: NeoBiota, 2020, vol. 62, p. 525–545

Extensive literature is available on the diversity and magnitude of impacts that alien species cause on recipient systems. Alien species may decrease or increase attributes of ecosystems (e.g. total biomass or species diversity), thus causing negative and positive environmental impacts. Alien species may also negatively or positively impact attributes linked to local human communities (e.g....

The past and future human impact on mammalian diversity

Andermann, Tobias ; Faurby, Søren ; Turvey, Samuel T. ; Antonelli, Alexandre ; Silvestro, Daniele

In: Science Advances, 2020, vol. 6, no. 36, p. eabb2313

To understand the current biodiversity crisis, it is crucial to determine how humans have affected biodiversity in the past. However, the extent of human involvement in species extinctions from the Late Pleistocene onward remains contentious. Here, we apply Bayesian models to the fossil record to estimate how mammalian extinction rates have changed over the past 126,000 years, inferring...

Decent Work for All : Rethinking Decent Work in the Context of South Africa

Ludwig, Carmen ; Webster, Edward

In: sozialpolitik.ch, 2020, vol. 2, no. 3, p. Article: 2.3

The authors argue that there is a need to rethink what a commitment to decent work would mean in the context of South Africa, a country with a large number of long term unemployed. Drawing on their experience of researching work in South Africa, they highlight the relevance of the agency of workers for the progressive realisation of a decent work agenda. The lukewarm response of the government to...

The prospect and challenges to the flow of liquid biopsy in Africa

Oluwaseyi Temilola, Dada ; Wium, Martha ; Coulidiati, Tangbadioa Herve ; Adeola, Henry Ademola ; Carbone, Giuseppina Maria ; Catapano, Carlo Vittorio Institute of Oncology Research (IOR), Faculty of Biomedical Sciences, Università della Svizzera italiana, Switzerland ; Zerbini, Luiz Fernando

In: Cells, 2019, vol. 8, no. 8, p. 862

Liquid biopsy technologies have the potential to transform cancer patient management as it others non- invasive diagnosis and real-time monitoring of disease progression and treatment responses. The use of liquid biopsy for non-invasive cancer diagnosis can have pivotal importance for the African continent where access to medical infrastructures is limited, as it eliminates the need for...

Pleistocene sea-floor fibrous crusts and spherulites in the Danakil Depression (Afar, Ethiopia)

Jaramillo‐Vogel, David ; Foubert, Anneleen ; Braga, Juan Carlos ; Schaegis, Jean‐Charles ; Atnafu, Balemwal ; Grobéty, Bernard ; Kidane, Tesfaye

In: Sedimentology, 2019, vol. 66, no. 2, p. 480–512

Pleistocene fibrous aragonite fabrics, including crusts and spherules, occur in the Danakil Depression (Afar, Ethiopia) following the deposition of two distinctive Middle and Late Pleistocene coralgal reef units and pre‐dating the precipitation of evaporites. Crusts on top of the oldest reef unit (Marine Isotope Stage 7) cover and fill cavities within a red algal framework. The younger...

Spatially varying selection shapes life history clines among populations of Drosophila melanogaster from sub-Saharan Africa

Fabian, D. K. ; Lack, J. B. ; Mathur, V. ; Schlötterer, C. ; Schmidt, P. S. ; Pool, J. E. ; Flatt, Thomas

In: Journal of Evolutionary Biology, 2015, vol. 28, no. 4, p. 826–840

Clines in life history traits, presumably driven by spatially varying selection, are widespread. Major latitudinal clines have been observed, for example, in Drosophila melanogaster, an ancestrally tropical insect from Africa that has colonized temperate habitats on multiple continents. Yet, how geographic factors other than latitude, such as altitude or longitude, affect life history in this...

Horizons in the evolution of aging

Flatt, Thomas ; Partridge, Linda

In: BMC Biology, 2018, vol. 16, no. 1, p. 93

Between the 1930s and 50s, evolutionary biologists developed a successful theory of why organisms age, firmly rooted in population genetic principles. By the 1980s the evolution of aging had a secure experimental basis. Since the force of selection declines with age, aging evolves due to mutation accumulation or a benefit to fitness early in life. Here we review major insights and challenges...
