Pandemic Citizenship by Design
During the COVID-19 pandemic, states around the world used smartphone apps to break chains of infection. Some functioned as a passport or enabled states to enforce certain rules on their citizens. Others, such as the German contact tracing app, were less intrusive, anonymously informing users about their high-risk encounters with an infected person. This article analyses how the German app configured state-citizen relations using infrastructure-b…
Whose crisis? Pandemic flu, 'communication disasters' and the struggle for hegemony
Public health authorities in Germany regard communication as a crucial part of infectious disease prevention and control strategies. Communication becomes even more important during public health crises such as pandemics. Drawing on Briggs and Hallin's concept of biocommunicability, we analysed the German National Pandemic Plan and key informant interviews with public health experts, critical infrastructure providers and ambulance services. We ex…

Asiatische Tigermücken als unerwünschte Grenzgänger
Cyborg Preparedness
Biopreparedness exercises are commonly depicted as indispensable means to enable people to respond to outbreaks of highly pathogenic infectious diseases. In this article, based on a 4-year multisited ethnography conducted in Frankfurt and London, we argue that exercises mobilize past and present events in a continuous rehearsal for the implementation and stabilization of emergency infrastructures. While relying on the embodied knowledge and the b…
Assessing Participant Compliance With Point-of-Use Water Treatment
Field studies on household water treatment and safe storage (HWTS) suggest that positive health outcomes are strongly linked to user compliance. We investigated factors that influenced compliance in a marginalized community of South India where residents worked with researchers to develop a water treatment intervention in absence of government water utilities. Survey and water quality data were collected during a 12-month randomized controlled tr…
Light penetration into Clarens sandstone and implications for deterioration of San rock art
In respect to the weathering of cave art exposed to the sun, cognizance has yet to be taken of the modified thermal conditions and the potential for endolithic biotic activity where the art is located on a light‐transmissive lithology. Where light penetrates rock, the light‐to‐heat transfer is not solely at the surface, and this leads to a thermal gradient that is different from where the paintings are located (and all transfer is at the surface)…
Minerals provide tints and possible binder/extender in pigments in san rock paintings (South Africa)
Minerals such as iron oxides and clays provide high tinting strength and improve the adhesive properties of pigments. In this study, we investigated the mineral composition of pigments from samples of San rock art. We used X‐ray diffraction and scanning electron microscopy to determine the mineral composition and micromorphology of pigments. Results showed that the major minerals in pigments in San rock art are whewellite, quartz, gypsum, hematit…

Nivation or cryoplanation
Nivation and cryoplanation are considered to produce separate landforms—hence their distinct names. However, despite this duality of terms, both utilize the same basic processes. A review of the literature indicates confusion and overlap regarding nivation and cryoplanation and their meaning. First, nivation is clearly described in its literature as exploiting pre‐existing hollows. Thus nivation cannot be the initiator of cryoplanation as is freq…
Zoological erosion in permafrost environments
In most cold‐region studies, animals as geomorphic agents have been considered “curiosities”; and thus not in need of study and quantification. Available evidence does, however, indicate that animals can be major causes of erosion and sediment transport. Furthermore, the zoogeomorphic effects may be exploited by other processes that would otherwise not occur. Permafrost is susceptible to degradation as a result of loss of the active layer. Surfac…
Polar geography at 20 years
Freeze‐thaw weathering
Freeze‐thaw weathering is commonly cited as a major agency of landform development in high latitudes and at high altitudes. This is, however, largely an unsubstantiated qualitative judgment. The reality is a paucity of data regarding key factors, such as rock temperature and interstitial rock moisture content data, necessary for the correct assumption of freeze‐thaw rock weathering. The problem is compounded when it is presumed that angular clast…
