„Und setzet eure Worte nicht auf Schrauben”︁ Medizinische Semiotik vom Ende des 18. bis zum Beginn des 20. Jahrhunderts - Gegenstand und Forschung

There is no doubt that medical semiotics are having a revival at the moment. Different aspects of yesterday's and today's interest in semiotics and in the historical interpretation of signs of disease in the context of theory and history of medicine can be illuminated: their deciphering as the history of the sign in medicine by historic science, their overestimation by philosophy during the Age of Enlightenment, their reduction to a phenomenology of medicine and natural science during the first half of the 19th century and their transformation to medical diagnostics since the middle of the 19th century and recently even their functionalization as methodical instrument within the history of science. The following will show the change in meaning of medical semiotics. Modern development and especially the transition to medicine, based on natural science, will be emphasized.     

Municipal land allocations: a key for understanding tenure and social mix patterns in Stockholm

A socially mixed population is a political ambition in Stockholm. By providing a mix of tenure alternatives throughout all neighbourhoods this objective could, at least partially, be fulfilled. Since current tenure proportions display a weak balance in many neighbourhoods it could be assumed that governing politicians – by primarily utilizing Stockholm’s vast landownership and municipal housing developers – attempt to bridge observed gaps. Distribution of new rental and ownership apartments in municipal land allocations should acknowledge the existing tenure composition in a neighbourhood. Methodically this article focuses on all (nearly 50,000) apartments channelled through Stockholm’s land allocation system between 2002 and 2012. After classification of all apartments based on tenure, location, year and developer (private or municipal) the information is merged with yearly housing stock characteristics for 128 neighbourhoods. The outcome is a unique data set allowing for statistical assessment of whether Stockholm’s tenure (and in extension social) mix ambition is reflected in practice. The present article aims to highlight the crucial importance of landownership in Swedish municipalities with an aspiration to achieve or maintain a balanced tenure mix. While the findings indicate Stockholm is complying fairly well with its ambition, the results do reveal some contradicting signs.     

Geochronology of plutonic rocks from the Sanandaj-Sirjan zone,Iran and new zircon and titanite U-Th-Pb ages for granitoids from the Marivan pluton

The Sanandaj-Sirjan zone of Iran is a metamorphic belt consisting of rocks which were metamorphosed under different pressure and temperature conditions and intruded by various plutons ranging in composition from gabbro to granite. The majority of these granitoids formed along the ancient active continental margin of the Neo-Tethyan ocean at the southeastern edge of the central Iranian microplate. Geochronological data published in recent years indicate periodic plutonism lasting from Carboniferous through Mesozoic to late-Paleogene times (from ca. 300 to ca. 35 Ma) with climax activity during the mid- and late-Jurassic. The age constraints for plutonic complexes, such as Siah-Kouh, Kolah-Ghazi, Golpayegan (Muteh), Azna, Aligoodarz, Astaneh, Borujerd, Malayer (Samen), Alvand, Almogholagh, Ghorveh, Saqqez, Marivan, Naqadeh and Urumieh, clearly indicate the periodic nature of magmatism. Therefore, the Sanandaj-Sirjan zone preserves the record of magmatic activity of a complete orogenic cycle related to (1) Permocarboniferous(?) rifting of Gondwana and opening of the Neo-Tethyan ocean, (2) subduction of the oceanic crust, (3) continental collision and (4) post-collision/post-orogenic activities. The formation of the Marivan granitoids, northwestern Sanandaj-Sirjan zone, for which we present U-Pb zircon and titanite ages of ca. 38 Ma, can be related to the collisional and post-collisional stages of this orogenic cycle.
