Zur Ausstattung etruskischer Klinengelage: Ergebnisse historischer und moderner Dokumentationen der Grabmalereien Tarquinias
Von 1988 bis 1995 wurden in einem von der DFG (Deutsche ForschungsgemeinschaftI geförderten Projekt in Zusammenarbeit mit der SAEM (Soprintendenza archeologica dell'Etruria meriodonale) alle zugĂ€nglichen Grabmalerei von Tarquina in neuen Durchzeichnungen im MaĂstab 1 : 1 aufgenommen. Am Beispiel eines der interessantesten Antiquaria der Gelageszenen, dem sog. Kylikeion, wird aufgezeigt, wie man anhand der neuen Zeichnungen und unter Zuhilfenahme der alten, auf die gleiche Weise erstellten Dokumentation des 19. Jhs. selbst in scheinbar hoffnungslosen FĂ€llen zu ĂŒberraschenden und fĂŒr die Interpretation der Gelage insgesamt wichtigen neuen Erkenntnissen kommen kann
SpÀtarchaische Gelagebilder in Tarquinia
Det huvudsakliga syftet med denna uppsats Àr att ur ett jÀmförande perspektiv studera argumentationsstrukturer i ett antal domsmotiveringar, avkunnade av RegeringsrÀtten (RR), frÄn 1972 och 2002. Genom en sÄdan analys kommer det att framgÄ bland annat vilka moment domsmotiveringen innehÄller samt pÄ vilka sÀtt rÀttskÀllorna anvÀnds. En för denna uppsats sÀrskilt viktiga frÄga Àr: mot bakgrund av vilka faktorer kan förÀndringen av argumentationsstrukturens karaktÀr förklaras? Om man pÄ ett mer djupgÄende sÀtt försöker förklara vad det Àr som bestÀmmer domsmotiveringens innehÄll och form mÄste man ta i beaktande faktorer som hör hemma inom rÀttssociologin. Det Àr hÀr den samhÀlleliga kontext som domstolen befinner sig i och den kollegiala socialiseringen kommer in i bilden. DÄ det Àr mitt samhÀllsintresse som inspirerat mig till att skriva denna uppsats kommer förklaringen till argumentationsstrukturens utveckling i första hand att sökas i den ideologiska förskjutning som skett de senaste trettio Ären. Uppsalaskolan Àr den lÀra som haft störst inflytande pÄ svensk juridik och det finns en hel del som tyder pÄ att argumentationskulturen inom domstolsvÀsendet Àr starkt prÀglad av HÀgerströmianismen. De förÀndringar som skett de senaste trettio Ären vad gÀller RR:s argumentationsteknik kan sammanfattas under följande punkter: större öppenhet i redovisningen av rÀttskÀllor, argumentationen innehÄller fler led, RR anvÀnder auktoritativa uttalanden i mindre utstrÀckning. Men pÄ en annan punkt har RR:s argumentationsstil inte förÀndrats nÀmnvÀrt. Det gÀller det sÀtt man redovisar de skÀl som haft avgörande betydelse för utgÄngen i mÄlet
DNA repair, DNA replication and human disorders: A personal journey
I was born in 1946 and grew up in the industrial north-west of England close to the city of Manchester. My parents were German- Jewish refugees, who left Germany fairly early, in 1933. My father helped to establish and was one of the directors of a tannery, which made leather for shoes and handbags. This was part of a group of tanneries established first in Strasbourg by my great-grandfather Ferdinand Oppenheimer. I would describe my childhood and adolescent years as comfortable by general post-war standards. I went to a state primary school and obtained a scholarship to Manchester Grammar School (MGS), a fairly prestigious secondary school. As a child I was always interested in chemistry but had little interest in or knowledge of biology. The educational system in the UK at that time was such that one had to specialise very early and as a consequence I have had no formal biology education since the age of 12, something I have managed to hide reasonably successfully for the rest of my life! In my final two years at MGS I studied just physics, chemistry and mathematics and obtained a scholarship to Pembroke College, Cambridge (England) to study Natural Sciences, with the intention of becoming a chemist. In the second year at Cambridge, one of the options was a course on biochemistry. Having no real idea what this was, I read a book about it in the summer of 1965, and was truly astonished and excited to discover that the basis of life was just a bunch of rather complicated organic chemistry reactions. So I took the biochemistry course in my second year. By the end of that year, I was fed up with chemistry and for my final year I chose to do biochemistry rather than chemistry, a decision I have not regretted. The biochemistry lectures must have been pretty up-to-date, as we were told briefly about the discovery of DNA repair by Dick Setlow [1], a topic that seemed rather esoteric at the time
Prevention of Acute Hematoma After Face-Lifts
Acute hematoma remains one of the most frequently encountered complications after face-lift surgery. Several risk factors inherent to the patient and omission of certain intraoperative regimens are considered to cause hematoma. Significant risk factors include high blood pressure and male gender. Possible intraoperative regimens for the prevention of hematoma include tumescence infiltration without adrenaline, clotting of raw surfaces with fibrin glue, usage of drains, and application of compression bandages. However, little attention has been paid to postoperative measures. To examine whether different regimens in the postoperative phase can influence the incidence of hematoma, all face-lift patients who underwent surgery by a single surgeon in two different clinics (n=376) with two different postoperative regimens were evaluated over the course of 3years. In group 1 (n=308), all postoperative medication was administered on request including medication for pain control, blood pressure stabilization, and prevention of nausea and vomiting as well as postoperative restlessness and agitation. In group 2 (n=68), this medication was administered prophylactically at the end of the operation before extubation. The hematoma rate was 7% in group 1 and 0% in group 2. This study showed that the prophylactic use of medications (e.g., analgesics, antihypertonics, antiemetics, and sedatives) during the postoperative phase is superior to making drugs available to patients on request and can decrease the occurrence of acute hematoma in face-lift patient
TALKING INSTITUTIONS IN THE SHARING ECONOMY: A CONTENT ANALYSIS OF ACTOR QUOTES IN THE PRINT MEDIA AND A TAXONOMY OF DISCURSIVE STRATEGIES
We study how actors engage in institutional work to manage legitimacy by influencing media discourse in the face of discontinuous innovation. We content-analyze actor quotes reproduced in newspaper articles about the âsharing economyâ in the taxi and lodging industries to survey this aspect of media discourse and offer a taxonomy of the discursive strategies used in the public debate on institutional change. We find that actor quotes are dominantly from offensive actors striving for institutional change, mostly due to a relatively low share of voice of incumbent firms as defensive actors aiming at institutional maintenance. Whereas offensive actors aimed for legitimacy in their discursive strategies by balancing attacks on existing institutions with assertions of new institutions, defensive actors aimed for legitimacy more by attacking new institutions than by reinforcing existing ones. Our findings suggest that, contrary to prior beliefs, preventing the emergence of new institutions plays a crucial role for defensive institutional work
Coherent charge transport through molecular wires: influence of strong Coulomb repulsion
We derive a master equation for the electron transport through molecular
wires in the limit of strong Coulomb repulsion. This approach is applied to two
typical situations: First, we study transport through an open conduction
channel for which we find that the current exhibits an ohmic-like behaviour.
Second, we explore the transport properties of a bridged molecular wire, where
the current decays exponentially as a function of the wire length. For both
situations, we discuss the differences to the case of non-interacting
electrons.Comment: 15 pages, 4 figures, elsart style, accepted at Chem Phy

Functional characterization of reappearing B cells after anti-CD20 treatment of CNS autoimmune disease.
The anti-CD20 antibody ocrelizumab, approved for treatment of multiple sclerosis, leads to rapid elimination of B cells from the blood. The extent of B cell depletion and kinetics of their recovery in different immune compartments is largely unknown. Here, we studied how anti-CD20 treatment influences B cells in bone marrow, blood, lymph nodes, and spleen in models of experimental autoimmune encephalomyelitis (EAE). Anti-CD20 reduced mature B cells in all compartments examined, although a subpopulation of antigen-experienced B cells persisted in splenic follicles. Upon treatment cessation, CD20+ B cells simultaneously repopulated in bone marrow and spleen before their reappearance in blood. In EAE induced by native myelin oligodendrocyte glycoprotein (MOG), a model in which B cells are activated, B cell recovery was characterized by expansion of mature, differentiated cells containing a high frequency of myelin-reactive B cells with restricted B cell receptor gene diversity. Those B cells served as efficient antigen-presenting cells (APCs) for activation of myelin-specific T cells. In MOG peptide-induced EAE, a purely T cell-mediated model that does not require B cells, in contrast, reconstituting B cells exhibited a naive phenotype without efficient APC capacity. Our results demonstrate that distinct subpopulations of B cells differ in their sensitivity to anti-CD20 treatment and suggest that differentiated B cells persisting in secondary lymphoid organs contribute to the recovering B cell pool
