Saving the Monopsony: Exclusivity, Innovation and Market Power in the Media Sector. Research Papers in Law, 7/2006

From the Introduction. The Media Sector has experienced a technological revolution in the last 15 years. Digital encoding of television signals made possible a more efficient use of the radiospectrum. Digital terrestrial television (hereinafter, “DTT”) allows now for the reception of a significant number of free-to-air channels.1 Moreover, the use of new transmission platforms (hereinafter,“platforms”), namely cable and direct-to-home satellite (hereinafter, “DTH”) paved the way for the arrival in Europe of pay-TV operators, which finance their activities mainly via subscription fees. This changing technological landscape is subject to further evolution in the near future, as incumbent telecommunications operators become increasingly interested in making available broadcasting content2 as part of their broadband offer and 3G mobile handsets can be used for the reception of TV signals....The present paper seeks to ascertain whether the Commission “regulatory approach” towards the exclusive sale of premium content is a sound one, in particular in view of the constant technological evolution outlined above. The assumptions underlying landmark Commission decisions will be compared with recent developments of the media sector in Italy. In the NewsCorp./Telepiù case, decided in 2003, the Commission imposed very strict conditions to allow the merger giving birth to Sky Italia, on the assumption that the operation created a lasting near-monopsony in the different upstream markets for the acquisition of premium intervened against the media conglomerate Mediaset (which controls, inter alia, the main three private free-to-air channels in Italy) for an alleged abuse of dominant position.17 In fact, and contrary to the forecasts made by the Commission, Mediaset was in a position to acquire the broadcasting rights of the main Italian football teams, thereby excluding the incumbent (and near-monopolist) pay-TV operator, Sky Italia. This may go to show that the reality of the sector is more complex and evolves faster than one may infer from the Commission practice, thus putting into question its stance regarding exclusivity. The experience of the evolution of the Italian media sector will be used as the starting point for the evaluation of alternative regulatory options.

European Foreign and Security Policy since the Lisbon Treaty – From Common to single? ZEI Discussion Paper C226, 2014

Since the Lisbon Treaty, all organizational conditions have been created for the systematic use of the Common Foreign and Security Policy (CFSP). Military and civil structures, especially the operational headquarters and associated common structures like transport command, have been established. Until now there has been limited activity in crisis resolution, outside of Bosnia and Macedonia, and therefore little has been done in replacement of NATO. It is therefore difficult to assess the development of the common policy on conflict prevention and crisis management and it has been shown that in all cases NATO should come into play as planned from the outset.

Special Education and the Risk of Becoming Less Educated in Germany and the United States. CES Germany & Europe Working Papers, No. 05.1, 13 December, 2004

Over the twentieth century, a growing group of students has been transferred into considerably expanded special education systems. These programs serve children with diagnosed impairments and disabilities and students with a variety of learning difficulties. Children and youth “with special educational needs” constitute a heterogeneous group with social, ethnic, linguistic, and physical disadvantages. An increasingly large percentage of those students at risk of leaving school without credentials participate in special education, a highly legitimated low status (and stigmatizing) school form. While most countries commit themselves to school integration or inclusive education to replace segregated schools and separate classes, cross-national and regional comparisons of special education’s diverse student bodies show considerable disparities in their (1) rates of classification, (2) provided learning opportunities, and (3) educational attainments. Analyzing special education demographics and organizational structures indicates which children and youth are most likely to grow up less educated and how educational systems distribute educational success and failure. Findings from a German-American comparison show that which students bear the greatest risk of becoming less educated depends largely on definitions of “special educational needs” and the institutionalization of special education systems.

On the initiation of boudinage and folding instabilities in layered elasto-visco-plastic solids - Insights from natural microstructures and numerical simulations

The present understanding of the initiation of boudinage and folding structures is based on viscosity contrasts and stress exponents, considering an intrinsically unstable state of the layer. The criterion of localization is believed to be prescribed by geometry-material interactions, which are often encountered in natural structures. An alternative localization phenomenon has been established for ductile materials, in which instability emerges for critical material parameters and loading rates from homogeneous conditions. In this thesis, conditions are sought under which this type of instability prevails and whether localization in geological materials necessarily requires a trigger by geometric imperfections. The relevance of critical deformation conditions, material parameters and the spatial configuration of instabilities are discussed in a geological context. In order to analyze boudinage geometries, a numerical eigenmode analysis is introduced. This method allows determining natural frequencies and wavelengths of a structure and inducing perturbations on these frequencies. In the subsequent coupled thermo-mechanical simulations, using a grain size evolution and end-member flow laws, localization emerges when material softening through grain size sensitive viscous creep sets in. Pinch-and-swell structures evolve along slip lines through a positive feedback between the matrix response and material bifurcations inside the layer, independent from the mesh-discretization length scale. Since boudinage and folding are considered to express the same general instability, both structures should arise independently of the sign of the loading conditions and for identical material parameters. To this end, the link between material to energy instabilities is approached by means of bifurcation analyses of the field equations and finite element simulations of the coupled system of equations. Boudinage and folding structures develop at the same critical energy threshold, where dissipative work by temperature-sensitive creep overcomes the diffusive capacity of the layer. This finding provides basis for a unified theory for strain localization in layered ductile materials. The numerical simulations are compared to natural pinch-and-swell microstructures, tracing the adaption of grain sizes, textures and creep mechanisms in calcite veins. The switch from dislocation to diffusion creep relates to strain-rate weakening, which is induced by dissipated heat from grain size reduction, and marks the onset of continuous necking. The time-dependent sequence uncovers multiple steady states at different time intervals. Microstructurally and mechanically stable conditions are finally expressed in the pinch-and-swell end members. The major outcome of this study is that boudinage and folding can be described as the same coupled energy-mechanical bifurcation, or as one critical energy attractor. This finding allows the derivation of critical deformation conditions and fundamental material parameters directly from localized structures in the field.

(Table T1) Gas hydrate fabric and dipping angles of ODP Leg 204 sediments

The sediments of Hydrate Ridge/Cascadia margin contain extensive amounts of gas hydrate. A total of 57 sediment samples including gas hydrate were preserved in liquid nitrogen and have been imaged using computerized tomography to visualize hydrate distribution and shape. The analysis gives evidence that gas hydrate in vein and veinlet structures is the predominant shape in the deeper gas hydrate stability zone with dipping angles from 30° to 90°(vertical).

Lithology description, textural and structural observations, and indications for ground ice of sediment core CRP-2 (Table 1-4)

From the upper 300 m of CRP-2/2A, twenty-six samples of diamicts and deformation structures have been thin sectioned. These have been analysed for texture, structure, diagenesis and plasmic fabric. The combination of certain microstructures (e.g. turbate and linear) and plasmic fabric development is indicative of grounded ice. Clear evidence for two grounded ice events (three samples) was found in the upper Oligocene part of the core. The interpretation of ten more samples is less certain, but as for CRP-1, is taken to point to grounded ice as well. There is a strong correlation between these indications for grounded ice and the basal part of cycles in the sequence stratigraphy.

AMS 14C and calibrated ages of sediment core GeoB10426-1

Newly acquired bathymetric and seismic reflection data have revealed mass-transport deposits (MTDs) on the northeastern Cretan margin in the active Hellenic subduction zone. These include a stack of two submarine landslides within the Malia Basin with a total volume of approximately 4.6 km**3 covering an area of about 135 km**2. These two MTDs have different geometry, internal deformations and transport structures. The older and stratigraphic lower MTD is interpreted as a debrite that fills a large part of the Malia Basin, while the second, younger MTD, with an age of at least 12.6 cal. ka B.P., indicate a thick, lens-shaped, partially translational landslide. This MTD comprises multiple slide masses with internal structure varying from highly deformed to nearly undeformed. The reconstructed source area of the older MTD is located in the westernmost Malia Basin. The source area of the younger MTD is identified in multiple headwalls at the slope-basin-transition in 450 m water depth. Numerous faults with an orientation almost parallel to the southwest-northeast-trending basin axis occur along the northern and southern boundaries of the Malia Basin and have caused a partial steepening of the slope-basin-transition. The possible triggers for slope failure and mass-wasting include (i) seismicity and (ii) movement of the uplifting island of Crete from neotectonics of the Hellenic subduction zone, and (iii) slip of clay-mineral-rich or ash-bearing layers during fluid involvement.

Inferior Hypogastric Plexus Block Affects Sacral Nerves and the Superior Hypogastric Plexus

Background. The inferior hypogastric plexus mediates pain sensation through the sympathetic chain for the lower abdominal and pelvic viscera and is thought to be a major structure involved in numerous pelvic and perineal pain syndromes and conditions. Objectives. The objective of this study was to demonstrate the structures affected by an inferior hypogastric plexus blockade utilizing the transsacral approach. Study Design. This is an observational study of fresh cadaver subjects. Setting. The cadaver injections and dissections were performed at the Department of Forensic Sciences and Insurance Medicine, Semmelweis University, Budapest, Hungary after obtaining institutional review board approval. Methods. 5 fresh cadavers underwent inferior hypogastric plexus blockade with radiographic contrast and methylene blue dye injection by the transsacral fluoroscopic technique described by Schultz followed by dissection of the pelvic and perineal structures to localize distribution of the indicator dye. Radiographs demonstrating correct needle localization by contrast spread in the specific tissue plane and photographs of the dye distribution after cadaver dissection were recorded for each subject. Results. In all cadavers the dye spread to the posterior surface of the rectum and the superior hypogastric plexus. The dye also demonstrated distribution to the anterior sacral nerve roots of S1, 2, and 3 with bilateral spread in 3 cadavers and ipsilateral spread in 2 of them. Limitations. The small number of cadaver specimens in this study limits the results and generalization of their clinical significance. Conclusions. Inferior hypogastric plexus blockade by a transsacral approach results in distribution of dye to the anterior sacral nerve roots and superior hypogastric plexus as demonstrated by dye spread in freshly dissected cadavers and not by local anesthetic spread to other pelvic and perineal viscera.

Integrating spatial optimization and cellular automata for evaluating urban change

Urban growth and change presents numerous challenges for planners and policy makers. Effective and appropriate strategies for managing growth and change must address issues of social, environmental and economic sustainability. Doing so in practical terms is a difficult task given the uncertainty associated with likely growth trends not to mention the uncertainty associated with how social and environmental structures will respond to such change. An optimization based approach is developed for evaluating growth and change based upon spatial restrictions and impact thresholds. The spatial optimization model is integrated with a cellular automata growth simulation process. Application results are presented and discussed with respect to possible growth scenarios in south east Queensland, Australia.

Discoloration and mineralization of Reactive Red HE-3B by heterogeneous photo-Fenton reaction

Discoloration and mineralization of Reactive Red HE-3B were studied by using a laponite clay-based Fe nanocomposite (Fe-Lap-RD) as a heterogeneous catalyst in the presence of H2O2 and UV light. Our experimental results clearly indicate that Fe-Lap-RD mainly consists of Fe2O3 (meghemite) and Fe2Si4O10(OH)2 (iron silicate hydroxide) which have tetragonal and monoclinic structures, respectively, and has a high specific surface area (472m(2) / g) as well as a high total pore volume (0.547 cm(3)/g). It was observed that discoloration of HE-3B undergoes a much faster kinetics than mineralization of HE-3B. It was also found that initial HE-3B concentration, H2O2 concentration, UV light wavelength and power, and Fe-Lap-RD catalyst loading are the four main factors that can significantly influence the mineralization of HE-3B. At optimal conditions, complete discoloration of 100 mg/L HE-3B can be achieved in 30 min and the total organic carbon removal ratio can attain 76% in 120 min, illustrating that Fe-Lap-RD has a high photo-catalytic activity in the photo-assisted discoloration and mineralization of HE-3B in the presence of UV light (254nm) and H2O2.
