Die Wandmalereien im Rittersaal von Schloss Friedberg bei Volders in Tirol

Die vorliegende Arbeit befasst sich mit den im Jahr 1967 wiederentdeckten maximilianischen Wandmalereien des sogenannten Rittersaales in Schloss Friedberg bei Volders in Tirol. Der um 1510 entstandene und in großen Teilen erhaltene Zyklus zeigt eine weite Landschaft, in welcher zahlreiche Menschen und Tiere agieren, davor ein ebenfalls gemalter, lebensgroßer Zaun. Aufgrund der Fortschrittlichkeit in der Naturdarstellung sowie der Erweiterung des in der bisherigen Tiroler Kunstgeschichte nur partiell realisierten Landschaftsausschnittes zum Panorama nimmt der Zyklus innerhalb dieser eine herausragende Position ein. Der Text erarbeitet nach einer Darlegung des Quellenmaterials die allgemeine Einbettung des Zyklusses in dessen Kontext durch eine Beleuchtung der profanen Wandmalerei Tirols der Zeit um 1500, einer Rekonstruktion der Baugeschichte der Burg Friedberg sowie der Auseinandersetzung mit dem Auftraggeber des Zyklusses im Rittersaal. Anhand der Bildbeschreibung sowie eines Restaurierberichts samt Vergleich mehrerer fotografisch dokumentierter Zustände aus verschiedenen Jahren erhält der Leser in der Folge einen detaillierten Einblick in die Darstellungswelt der Malereien und deren wechselndes äußeres Erscheinungsbild im Lauf der Jahrzehnte. Den verschiedenen gezeigten Themenbereichen, welche sich unter den Schlagwörtern „Krieg“ und „Frieden“ zusammenfassen lassen, ist ein eigenes Kapitel gewidmet. Es folgt die Auseinandersetzung mit konkreten Vorbildern für den Friedberger Zyklus sowie dessen Einordnung in den Zeitstil. Ersteres betreffend werden neben der Überprüfung von in der Literatur bereits genannten Vorlagen weitere Vorschläge hinzugefügt. Eine wichtige Erkenntnis dieses Kapitels besteht darin, dass der unbekannte Friedberger Meister nicht streng einer Überlieferungstradition folgte, sondern großzügig aus der Fülle zeitgenössischen Materials zu schöpfen schien. Auch die stilistische Einordnung der Malereien ergibt ein selbstständig agierendes Charakterbild des Künstlers. Kurz auf die Zuweisungsfrage an Jörg Kölderer eingehend gelange ich zu dem Schluss, dass der ausführende Künstler in dessen Umkreis zu suchen ist, ihm selbst aufgrund markanter stilistischer Unterschiede aber nicht zugeschrieben werden kann. Abschließend geht der Text näher auf das Panorama als Typus der Friedberger Wandmalereien ein. Nach einer Skizzierung seiner Entwicklungslinie lässt sich der Zyklus in den größeren ihn umgebenden Zusammenhang einordnen und seine Besonderheiten heben sich noch klarer hervor

A decade of energy and mass balance investigations on the glacier Kongsvegen, Svalbard

Kongsvegen is an Arctic glacier located in northwest Spitzbergen. We use meteorological observations made near the average equilibrium line of Kongsvegen during the decade 2001 to 2010 to drive a glacier energy and mass balance model. Average daily and seasonal cycles are analyzed over the course of a full decade, as well as the interannual variations of the meteorological parameters and of the mass and energy balance components. The calculated average of net radiation is close to zero and the sensible heat flux is the most important and continuous source of energy at the surface. The latent heat flux is a weak source of energy as well. The resultant flux constellation yields a surplus of energy accumulating throughout the decade (9.5 W m-2) and fosters a negative specific surface mass balance throughout the investigated decade (-1.8 m w. eq.). The most significant mass loss occurred during the middle of the decade (2004 until 2006), with positive surface mass balances observed afterward when significant amounts of superimposed ice were formed. This development is well correlated to the total surface mass balance of the glacier. Application of monthly temperature and precipitation perturbations corroborates earlier studies indicating a high sensitivity of the mass balance to energy fluxes depending on temperature conditions during summer.

Аутсорсінгова модель реалізації корпоративної соціальної відповідальності

У статті обґрунтовано необхідність і визначено шляхи використання аутсорсінгу корпоративної соціальної відповідальності в соціальній політиці України. Основним аргументом на користь такого аутсорсінгу є надзвичайна складність (а відтак – і ресурсоємність) процесу управління програмами корпоративної соціальної відповідальності. Використання різних форм (насамперед, повної та часткової) аутсорсінгу корпоративної соціальної відповідальності має найбільшу перспективу на регіональному рівні здійснення соціальної політики – в структурі фондів розвитку громади.В статье обоснована необходимость и определены пути использования аутсорсинга корпоративной социальной ответственности в социальной политике Украины. Основным аргументом в пользу такого аутсорсинга служит чрезвычайная сложность (а значит – и ресурсоемкость) процесса управления программами корпоративной социальной ответственности. Использования разных форм (прежде всего, полной и частичной) аутсорсинга корпоративной социальной ответственности имеет наибольшую перспективу на региональном уровне осуществления социальной политики – в структуре фондов местного развития.The paper argues the necessity and defines means of application of outsourcing to corporate social responsibility (CSR) in social policy of Ukraine. As CSR (corporate charity) is a secondary (not-product-related) activity to any for-profit organization, the allocation of recourses (human, managerial, financial etc.) to this activity may decrease effectiveness of the major (productrelated) functions, lessening the competitive ability of an enterprise. Initiation of specialized CSR-departments within an organizational structure (in order to provide expenditure control, feedback control and social effect monitoring) is a luxury, which most businesses in Ukraine can not afford. CSR-ignoring practices contradict imperatives of conventional modern business rules (e.g. sustainable development doctrine), which have presented CSR as a “must” for prosperous firms and successful for-profits throughout the world. Ukraine is also involved in the deployment of those imperatives as a new market economy country. Taking the burden of CSR-caused extra costs off a firm, outcontracting of CSR may contribute to wide spreading of corporate philanthropy, thus providing social policy and social-oriented activities in Ukraine with potentially essential assets. The paper derives, that deployment of CSR-outsourcing will produce the best effect on the regional level of social policy of Ukraine – within community foundations as community-based non-profit organizations, usually established in an area to help solving local social problems through accumulation and distribution chiefly local resources, aimed for social projects and programs of different kind

Measurement and simulation of the 16/17 April 2010 Eyjafjallajökull volcanic ash layer dispersion in the northern Alpine region

The spatial structure and the progression speed of the first ash layer from the Icelandic Eyjafjallajökull volcano which reached Germany on 16/17 April is investigated from remote sensing data and numerical simulations. The ceilometer network of the German Meteorological Service was able to follow the progression of the ash layer over the whole of Germany. This first ash layer turned out to be a rather shallow layer of only several hundreds of metres thickness which was oriented slantwise in the middle troposphere and which was brought downward by large-scale sinking motion over Southern Germany and the Alps. Special Raman lidar measurements, trajectory analyses and in-situ observations from mountain observatories helped to confirm the volcanic origin of the detected aerosol layer. Ultralight aircraft measurements permitted the detection of the arrival of a second major flush of volcanic material in Southern Germany. Numerical simulations with the Eulerian meso-scale model MCCM were able to reproduce the temporal and spatial structure of the ash layer. Comparisons of the model results with the ceilometer network data on 17 April and with the ultralight aircraft data on 19 April were satisfying. This is the first example of a model validation study from this ceilometer network data

Influences of the 2010 Eyjafjallajökull volcanic plume on air quality in the northern Alpine region

A series of major eruptions of the Eyjafjallajökull volcano in Iceland started on 14 April 2010 and continued until the end of May 2010. The volcanic emissions moved over nearly the whole of Europe and were observed first on 16 April 2010 in Southern Germany with different remote sensing systems from the ground and space. Enhanced PM10 and SO2 concentrations were detected on 17 April at mountain stations (Zugspitze/Schneefernerhaus and Schauinsland) as well as in Innsbruck by in situ measurement devices. On 19 April intensive vertical mixing and advection along with clear-sky conditions facilitated the entrainment of volcanic material down to the ground. The subsequent formation of a stably stratified lower atmosphere with limited mixing near the ground during the evening of 19 April led to an additional enhancement of near-surface particle concentrations. Consequently, on 19 April and 20 April exceedances of the daily threshold value for particulate matter (PM10) were reported at nearly all monitoring stations of the North Alpine foothills as well as at mountain and valley stations in the northern Alps. The chemical analyses of ambient PM10 at monitoring stations of the North Alpine foothills yielded elevated Titanium concentrations on 19/20 April which prove the presence of volcanic plume material. Following this result the PM10 threshold exceedances are also associated with the volcanic plume. The entrainment of the volcanic plume material mainly affected the concentrations of coarse particles (>1 μm) – interpreted as volcanic ash – and ultrafine particles (<100 nm), while the concentrations of accumulation mode aerosol (0.1–1 μm) were not changed significantly. With regard to the occurrence of ultrafine particles, it is concluded that their formation was triggered by high sulphuric acid concentrations which are necessarily generated by the photochemical processes in a plume rich in sulphur dioxide under high solar irradiance. It became evident that during the course of several days, the Eyjafjallajökull volcanic emissions influenced the near-surface atmosphere and thus the ambient air quality. Although the volcanic plume contributed to the overall exposure of the population of the northern Alpine region on two days, only minor effects on the exacerbation of respiratory and cardiovascular symptoms can be expected
