The expensive energy revolution in Germany. The implementation of the Energiewende is behind schedule. OSW Commentary No. 77, 2012-05-10

One year after the events of Fukushima the implementation of the new German energy strategy adopted in the summer of 2011 is being verified. Business circles, experts and publicists are sounding the alarm. The tempo at which the German economy is being rearranged in order that it uses renewable energy sources is so that it has turned out to be an extremely difficult and expensive task. The implementation of the key guidelines of the new strategy, such as the development of the transmission networks and the construction of new conventional power plants, is meeting increasing resistance in the form of economic and legal difficulties. The development of the green technologies sector is also posing problems. The solar energy industry, for example, is excessively subsidised, whereas the subsidies for the construction of maritime wind farms are too low. At present, only those guidelines of the strategy which are evaluated as economically feasible by investors or which receive adequate financial support from the state have a chance of being carried through. The strategy may also turn out to be unsuccessful due to the lack of a comprehensive coordination of its implementation and the financial burden its introduction entails for both the public and the economy. In the immediate future, the German government will make efforts not only to revise its internal regulations in order to enable the realisation of the energy transformation; it is also likely to undertake a number of measures at the EU forum which will facilitate this realisation. One should expect that the German government will actively support the financing of both the development of the energy networks in EU member states and the development of renewable energy sources in the energy sector.

Feeding preference and deterrence in rabbitfish Siganus fuscescens for the cyanobacterium Lyngbya majuscula in Moreton Bay, south-east Queensland, Australia

Rabbitfish Siganus fuscescens preferences for Lyngbya majuscula collected from three bloom locations in Moreton Bay, Queensland, Australia, were tested along with a range of local plant species in the laboratory. Consumption of L. majuscula by fish did not differ between wild and captive-bred fish (P = 0.152) but did differ between bloom location (P = 0.039). No relationship was found between consumption rates and lyngbyatoxin-a concentration (r(2) = 0.035, P = 0.814). No correlation existed between C : N and proportion of food consumed when all food types were analysed statistically, whereas a clear correlation was observed when L. majuscula was removed from the calculations. In simulated bloom conditions, fish avoided ingestion of L. majuscula by feeding through gaps in the L. majuscula coverage. Both wild and captive-bred S. fuscescens showed a distinct feeding pattern in 10 day no-choice feeding assays, with less L. majuscula being consumed than the preferred red alga Acanthophora spicifera. Lyngbya majuscula however, was consumed in equal quantities to A. spicifera by wild S. fuscescens when lyngbyatoxin-a was not detectable. Wild fish probably do not preferentially feed on L. majuscula when secondary metabolites are present and are not severely impacted by large L. majuscula blooms in Moreton Bay. Furthermore, poor feeding performance in both captive-bred and wild S. fuscescens suggests that they would exert little pressure as a top-down control agent of toxic L. majuscula blooms within Moreton Bay.

Stoichiometric and kinetic characterisation of Nitrosomonas sp in mixed culture by decoupling the growth and energy generation processes

A novel method that relies on the decoupling of the energy production and biosynthesis processes was used to characterise the maintenance, cell lysis and growth processes of Nitrosomonas sp. A Nitrosolnonas culture was enriched in a sequencing batch reactor (SBR) with ammonium as the sole energy source. Fluorescent in situ hybridization (FISH) showed that Nitrosomonas bound to the NEU probe constituted 82% of the bacterial population, while no other known ammonium or nitrite oxidizing bacteria were detected. Batch tests were carried out under conditions that both ammonium and CO, were in excess, and in the absence of one of these two substrates. The oxygen uptake rate and nitrite production rate were measured during these batch tests. The results obtained from these batch tests, along with the SBR performance data, allowed the determination of the maintenance coefficient and the in situ cell lysis rate, as well as the maximum specific growth rate of the Nitrosomonas culture. It is shown that, during normal growth, the Nitrosomonas culture spends approximately 65% of the energy generated for maintenance. The maintenance coefficient was determined to be 0.14 - 0.16 mgN mgCOD(biomass)(-1) h(-1), and was shown to be independent of the specific growth rate. The in situ lysis rate and the maximum specific growth rate of the Nitrosomonas culture were determined to be 0.26 and 1.0 day(-1) (0.043 h(-1)), respectively, under aerobic conditions at 30 degrees C and pH7.

'Looking good, feeling better': Consumption, Control and the Aesthetics of Exclusivity in the Service Encounter

The majority of ‘service’ literature has focused on the production side of service work (i.e. employees and management), while treating the role of the customer and/or consumer as secondary (Korczynski and Ott, 2004). Those authors who have addressed the role consumption plays in shaping and maintaining individuals' self- identity have tended to overemphasize the dominance of consumer culture in shaping ‘our consciousness’ (Ritzer, 1999), with little in the way of empirical evidence to support these assertions. This paper develops the conceptualization of service work and consumer culture literature, by placing more emphasis on the customer in the service encounter. Using an ethnographic study of a ‘high class’ department store, this paper addresses employee and customer identity and the nature of managerial, employee and customer control within this ‘exclusive’ context. Of particular interest is how employees and customer’s ‘embody’ this control. Using Bourdieu’s (1986) conception of class and habitus, the concept of exclusivity goes beyond the management /service worker dyad by providing a means of investigating identity control by the organization over both customers and service workers. However, an organization’s exclusivity is not a closed normative pursuit of control, and shows this enterprise is part of a contested terrain, while revealing the ambiguity and ‘openness’ of control practices and pursuits. In order to uphold the ideal of exclusivity, management, service workers and customers must all engage in a precarious quest for establishing and maintaining a sense of control and/or identity. This paper demonstrates the continuing contradiction between bureaucratic practices of control and consumer culture, and highlights the need for research that investigates the context -dependent nature of control in service-related and consumer studies.

Technical innovation in industrial production

New techniques in manufacturing, popularly referred to as mechanization and automation, have been a preoccupation of social and economic theorists since the industrial revolution. A selection of relevant literature is reviewed, including the neoclassical economic treatment of technical change. This incorporates alterations to the mathematical production function and an associated increase in the efficiency with which the factors of production are converted into output. Other work emphasises the role of research and development and the process of diffusion, whereby new production techniques are propagated throughout industry. Some sociological writings attach importance to the type of production technology and its effect on the organisational structure and social relations within the factory. Nine detailed case studies are undertaken of examples of industrial innovation in the rubber, automobile, vehicle components, confectionery and clothing industries. The old and new techniques are compared for a range of variables, including capital equipment, labour employed, raw materials used, space requirements and energy consumption, which in most cases exhibit significant change with the innovation. The rate of output, labour productivity, product quality, maintenance requirements and other aspects are also examined. The process by which the change in production method was achieved is documented, including the development of new equipment and the strategy of its introduction into the factory, where appropriate. The firm, its environment, and the attitude of different sectors of the workforce are all seen to play a part in determining the motives for and consequences which flow from the innovations. The traditional association of technical progress with its labour-saving aspect, though an accurate enough description of the cases investigated, is clearly seen to afford an inadequate perspective for the proper understanding of this complex phenomenon, which also induces change in a wide range of other social, economic and technical variables.

A New Approach for Eliminating the Spurious States in Recurrent Neural Networks

As is well known, the Convergence Theorem for the Recurrent Neural Networks, is based in Lyapunov ́s second method, which states that associated to any one given net state, there always exist a real number, in other words an element of the one dimensional Euclidean Space R, in such a way that when the state of the net changes then its associated real number decreases. In this paper we will introduce the two dimensional Euclidean space R2, as the space associated to the net, and we will define a pair of real numbers ( x, y ) , associated to any one given state of the net. We will prove that when the net change its state, then the product x ⋅ y will decrease. All the states whose projection over the energy field are placed on the same hyperbolic surface, will be considered as points with the same energy level. On the other hand we will prove that if the states are classified attended to their distances to the zero vector, only one pattern in each one of the different classes may be at the same energy level. The retrieving procedure is analyzed trough the projection of the states on that plane. The geometrical properties of the synaptic matrix W may be used for classifying the n-dimensional state- vector space in n classes. A pattern to be recognized is seen as a point belonging to one of these classes, and depending on the class the pattern to be retrieved belongs, different weight parameters are used. The capacity of the net is improved and the spurious states are reduced. In order to clarify and corroborate the theoretical results, together with the formal theory, an application is presented.

The end of stigma? Understanding the dynamics of legitimisation in the context of TV series consumption

This research contributes to prior work on stigmatisation by looking at stigmatisation and legitimisation as social processes in the context of TV series consumption. Using in-depth interviews, we show that the dynamics of legitimisation are complex and accompanied by the reproduction of existing stigmas and creation of new stigmas.
