Rhizoids, technicism and economism
A highly differentiated society requires integration. Dooyeweerd refers in this regard to science and technology. Intersocietal linkages play a key role in this process. They are affected, however, by technicism and economism. Rhizoids are configurations or distinct patterns of intersocietal relationships, linking activities in society to the kingdoms of material things, plants and animals. A delineated theory of rhizoids is given, especially configured as technical-economic relationships. The article defines elements of rhizoids such as flows, stows and transformations. In principle, rhizoids enable all important economic dispositions, including non-monetary ones, to be accounted for. This is important if economising is to take place within ecological limits. The presence and impacts of technicism and economism may be discerned in the shape and operation of rhizoids. An application to the treadmill problem in agricultural production for world markets is outlined. This is followed by a brief discussion of the spirit of capitalism, as reflected in technicism and economism (the earth is seen as a machine). They trigger a dialectical movement, leading to the establishment of smaller local rhizoids as alternatives to global ones. Schuurman?s plea for a paradigm shift towards seeing the earth as a garden-city offers a way of escaping from such dialectics
Economism
Modern society is characterised not only by a fascination with scientific technology as a means of solving all problems, especially those that stand in the way of material progress (technicism), but also by an obsessive interest in everything that has to do with money (economism or mammonism). The article discusses the relationship between technicism and economism, on the basis of their relationship to utilitarian thinking: the quest for the greatest happiness for the greatest number of people. Recent major studies of neo-liberalism (seen as an intensification of utilitarianism) by Laval and Dardot are used as reference to the development of utilitarianism. It is suggested that the western view of the world, as expressed in economism and technicism, with a utilitarian ethics, features three absolutisations: those of theoretical thinking, technology and economics. In a second part, the article draws on the framework of reformational philosophy to suggest an approach that, in principle, is not marred by such absolutisations
CDC42 and Rac1 control different actin-dependent processes in the Drosophila wing disc epithelium.
Cdc42 and Rac1 are members of the rho family of small guanosinetriphosphatases and are required for a diverse set of cytoskeleton-membrane interactions in different cell types. Here we show that these two proteins contribute differently to the organization of epithelial cells in the Drosophila wing imaginal disc. Drac1 is required to assemble actin at adherens junctions. Failure of adherens junction actin assembly in Drac1 dominant-negative mutants is associated with increased cell death. Dcdc42, on the other hand, is required for processes that involve polarized cell shape changes during both pupal and larval development. In the third larval instar, Dcdc42 is required for apico-basal epithelial elongation. Whereas normal wing disc epithelial cells increase in height more than twofold during the third instar, cells that express a dominant-negative version of Dcdc42 remain short and are abnormally shaped. Dcdc42 localizes to both apical and basal regions of the cell during these events, and mediates elongation, at least in part, by effecting a reorganization of the basal actin cytoskeleton. These observations suggest that a common cdc42-based mechanism may govern polarized cell shape changes in a wide variety of cell types

The Moon Glistens: A New Work for Band by Joni Greene: A Conductor's Analysis
This document serves as an examination of Joni Greene's (b. 1981) piece, The Moon Glistens (2014). Included within this paper are chapters dedicated to: biographical information of the composer, information about the commission of the work, a conductor's analysis including references to the original choral work Autumn Reflections, rehearsal considerations, and final thoughts regarding the composer's music
Diseases of winter linseed : occurrence, effects and importance
In 1998, a survey of the incidence and severity of diseases was carried out on 30 crops of winter linseed at early flowering and again at crop maturity. Five crops each were selected in south west, east, east Midlands, west Midlands and north of England and from Scotland. Crops were predominantly cv. Oliver (90% crops), grown from certified seed (83%) and sown in September (97%). Pasmo (Mycosphaerella) was the most important disease, affecting leaves of 73% crops at early flowering and 90% crops at maturity. Powdery mildew (70% crops), Alternaria (30% crops) on leaves and Botrytis on capsules (70% crops) were also common. Regional differences were apparent for powdery mildew, which was present in all regions except the southwest, whilst Alternaria predominated in the Midlands. Half of the crops surveyed had received fungicide sprays, but this appeared to have made limited impact on disease severity. Pasmo is a new threat to UK linseed crops and this raises concerns about the threat it poses to spring linsee
