Identifying Drivers and Enablers of the Sovereign Shift toward a Plant-Based Food Culture: The Case of Freiburg im Breisgau

Jordan Rydman

Languages: English

This Master’s Thesis Project uses a multidisciplinary approach to identify the drivers of a sovereign transformation in the food culture of Freiburg im Breisgau, Germany from traditional to more plant-based consumption. The research is positioned against the key concept of social resiliency as an important indicator of sustainability, requiring improved resilience of food systems as food cultures are disturbed in the face of climate-induced import flow precarity and ecological instability. The project focuses on the adoption of a plant-based food culture as a means for improving social and ecological resilience, considering cultural acceptability as an important indicator of a sovereignly sustainable diet as well as the ecological benefits of plant-based diets compared to diets rich in animal products.

Inscribing Expositions: Curatorial Strategies in Packing Practice into the Journal for Artistic Research

Chiara Giardi

Languages: English

DOI: 10.17160/josha.10.4.930

In this thesis, I inquire about curatorial strategies in research-based artistic practices by focusing on the six expositions (i.e. contributions) published in the 26th issue of the Journal for Artistic Research (JAR). Specifically, I’m interested in how the authors packed their practice into the expositions: What curatorial strategies were involved in this process? Furthermore, I ask whether the concept of “circulating reference” (Latour 1999b) could help to understand the chain of transformations (or inscriptions?) that allows the contributions to claim knowledge. I interviewed all the authors to reconstruct the steps they followed to transform their research/practice into a published product and I analysed the expositions as if they were online exhibitions. I clustered five areas of interest from a curatorial perspective (e.g. to implement a concept) and focused on specific episodes of the packing process that I identify as strategies (e.g.

Inhibition of Microbial Biofilm by the Crude Extracts of Marine Sponge, Stylissa masa

Suman Mallick

Languages: English

DOI: 10.17160/josha.10.4.926

Though a number of studies in relation to fouling and antifouling have been carried out throughout the world, few studies on antifouling compounds from marine natural sources have been carried out to address fouling in Andaman and Nicobar Islands (Patro et al., 2009). There is a real need for the continuous development of new non-toxic antifouling formulations. An ideal antifouling formulation would have the following properties: permit at least five years of biofouling life cycle control, durable and resistant to damage, repairable, low maintenance, easy to apply, hydraulically smooth, compatible with existing anticorrosion coating, cost-effective, non-toxic to non-target species, and, effective at port and sea. An interesting and promising line of research is inspired by biomimetic solutions.

Analysis of Extracellular Vesicles (EVs) Derived from CAR-T Cells

Maria Margarita Labastida Arzate

Languages: English

DOI: 10.17160/josha.10.4.924

Extracellular vesicles (EVs) conform a heterogeneous group of lipid bilayer membrane particles naturally released by cells. They vary in size, surface composition, mechanism of formation, biochemical content, and function within the human body. EVs are classified in 3 groups, depending on their size and biogenesis: exosomes (originated by the endolysosomal system, measuring 60-150nm in diameter), microvesicles (direct budding from the plasma membrane, measure 100 – 1000 nm size) and apoptotic bodies (released by dying cells, size >1μm). A very important feature of the EVs is the delivery of information by horizontal transfer between the origin cell and the recipient one, evidence suggests that the uptake of EVs by recipients’ cells can induce changes in their own characteristics and function. CAR T-cells are genetically modified T-cells that express on their surface a Chimeric Antigen T-cell Receptor (CAR) specific for a unique antigen expressed in the surface of tumor cells.

Dear josha-journal readers, Before the summer really starts in Europe, josha-journal deals with a variety of topics, especially, as a warning, with a serious issue concerning German history. George M. Weisz, in his excellent study, elaborates the similarities between the genocide of Herero and Nama in Namibia and the Nazi genocide of European Jews and other groups. This should always be a warning not to forget history and to draw a lesson from it for the present and the future. We at josha-journal are committed to community and international exchange. Wherever you stay in the world and read the journal: Stay tuned to us.

Modelling Spatial Scale and Heterogeneity in Rotterdam Housing Market Using Multiscale Geographically Weighted Regression

Naftali Feddes

Languages: English

DOI: 10.17160/josha.10.4.915

This study investigates the spatial heterogeneity of the Rotterdam housing market, as well as the spatial scale at which the processes that explain housing prices operate. I use data on 3632 residential properties that were sold in Rotterdam in 2018 provided by the NVM. Using a recently (2017) developed technique called Multiscale Geographically Weighted Regression (MGWR), I show that certain factors explaining residential housing prices operate on different spatial scales, indicating the existence of relatively local and more global effects. Lot size and the state of maintenance of the house exterior seem to operate on a local scale, whereas the degree of isolation and number of rooms appear to be global. Comparison of the MGWR model with a regular GWR with fixed bandwidths and a global hedonic model with location fixed effects, show that the MGWR best fits the data, i.e. a model that allows the bandwidths to vary for each parameter outperforms the models that do not allow this.

GENOCIDE: From the Second Empire's Namibia, to the Third Reich’s Birkenau

George M. Weisz

Languages: English

DOI: 10.17160/josha.10.3.908

The concept of the Empire (Reich) of the German Nations was first established by Otto I in the year 962. It was revived from the defunct Holy Roman Medieval one at a post war conference in Versailles, in 1871. This revival became a reality by the unification of the dispersed German states, with Otto v. Bismarck named as chancellor and William I, as emperor.(1871-88). It was however, in 1884 at a meeting in Berlin, that the European states divided the potential African colonies. Consequently, Germany was granted a colony on the South/Western African coast, in today’s Namibia, the land of Hehero and Nama. Starting as an economic enterprise (tobacco, metals, diamonds, and cattle), this soon became a racially driven Genocide, which included medical experiments. The similarities of the Second Reich with the coming Third Reich were described by many historians.
