Fotografie als Wissenschaft

Photography as Science: In 1908 the English physicist Arthur Mason Worthington published A Study of Splashes, a treatise on the physical behaviour of falling drops. The photographic experiments were performed by means of an electric spark „in absolute darkness”︁. Worthington's experimental practice dealt with two different areas of knowledge production: an area the operator could perceive control from the outside and a corresponding black-box where the photographic recording itself took place. The paper discusses the epistemic challenges of this specific shift from imperceptible events to their photographic representations. It shows to what extent the information revealed by the photographic apparatus had to be converted, for it did not speak for itself. Thus, Worthington's work went beyond the classical dichotomy between objectivity and imagination.     

What really goes on in Silicon Valley? Spatial clustering and dispersal in modular production networks

Is the geographic trajectory of capitalism toward spatial clusteringor dispersal? Recent theoretical work in the stream of ‘relational’economic geography includes several dynamic elements that increasethe importance of spatial clustering over time. This paper developsthe concept of ‘modular production networks’ toshow that spatial clustering and dispersal can be compatible,mutually reinforcing trends. Modular production networks encompassnodes of tacit activity linked through the exchange of codifiedinformation to create global-scale production systems. In placeslike Silicon Valley, industry participants rely on the benefitsof proximity to help build and manage global-scale productionnetworks.     

Plant processing strategies and their affect upon starch grain survival when rendering Peltandra virginica (L.) Kunth,Araceae edible

There is a long history of human interaction with plants of the Aroideae subfamily (Araceae). Despite these plants' chemical defenses against animal and vegetal predation, humans have targeted their starchy corms, tubers and rhizomes for dietary purposes. In the Eastern Woodlands of North America, early Europeans described the Native population as utilizing the highly acridic Peltandra virginica (arrow arum) for subsistence needs. In order to render this resource edible, however, the acridic principle first needs to be eliminated. Our study investigates the affect these processing activities have on the integrity of arrow arum starch grains. Findings from this study demonstrate that environmental variables specific to individual processing procedures may be more influential on starch grain survival than simply the temperatures reached during cooking.
