Der "tolle Mensch" und der "alte Gott" : ein Essay über Nietzsches Apokalypse der modernen Existenz
(2013)
"Wohin ist Gott? rief er, ich will es euch sagen! Wir haben ihn getödtet, - ihr und ich! Wir alle sind seine Mörder!" Diese berühmten Sätze des 'tollen Menschen' aus Friedrich Nietzsches Werk 'Die Fröhliche Wissenschaft' sind keineswegs an bekennende Fromme gerichtet, um sie von ihrem Gottesglauben abzubringen und vom Atheismus zu überzeugen. Sein entsetzter Ausruf richtet sich vielmehr an die Atheisten oder sonstige Ungläubige. Aber diesen Ausruf tat er auch nicht, um sie in ihrem wissenschaftlichen oder unwissenschaftlichen Unglauben zu bestärken. Nein! Er ruft ihnen diese schier unglaubliche Wahrheit zu, um sie mit der Frage zu konfrontieren, ob sie, die Gott getötet haben, überhaupt wissen, was sie angerichtet haben, ob sie sich der Konsequenz ihrer ungeheuerlichen Tat bewußt sind.Der 'tolle Mensch' distanziert sich dabei keineswegs von seinen gottlosen Zuhörern; im Gegenteil: ausdrücklich rechnet er sich ihnen zu. Aber im Gegensatz zu den angeredeten Gottesmördern hat er begriffen, was für eine furchtbare Existenzkatastrophe sie gemeinsam heraufbeschworen haben.
Wer ist aber dieser Gott, den Nietzsche den 'alten Gott' nennt, und den er, der 'tolle Mensch' und seine Zuhörer auf dem Marktplatz der Moderne getötet haben?
Seit mehr als 14 Jahrhunderten glauben Muslime, Sunniten wie Schiiten, daran, dass der Prophet Muhammad (gest. 632) der letzte Prophet sei und nach ihm bis zum jüngsten Tag weder weitere Propheten noch Gesandte kommen werden. Im 19. Jahrhundert ist eine neue islamische Bewegung in Erscheinung getreten. Diese neue islamische Glaubensgemeinschaft der sogenannten "Ahmadiyya"1 wurde 1891 von Mirza Ghulam Ahmad im indischen Punjab ins Leben gerufen. Anfangs erhob er den Anspruch, ein Erneuerer (mugaddid) des Islam zu sein. Einige Jahre später ging er, über seinen Aufruf zur Erneuerung hinausgehend, dazu über zu erklären, er sei der verheißene Messias und Mahdi2 des Islam. Schließlich verkündete er, göttliche Offenbarungen erhalten zu haben und ein Prophet Gottes zu sein. Diese Verkündigungen widersprechen, theologisch gesehen, eindeutig den Glaubenslehren der orthodoxen Muslime und riefen folglich ihren Zorn hervor. Trotzdem wurde die Ahmadiyya als eine unabhängige islamische Gemeinde im Jahre 1901 in Qadian registriert. ...
The aim of this study is to examine the different grades students’ understanding levels of the concept of religion in elementary education. A total of 107 different grades students taken from elementary schools were asked the concept in using open ended question developed by the researcher. Obtained data showed that students couldn’t understand the concept correctly and scientifically and the majority of the students had a misconception about the concept such as worshipping, worships, being ethical, ethical behaviours and obligatory behaviours. Furthermore, some students had specific conceptual confusions about the concept.
Sowohl die exklusive Vermarktung steuerfinanzierter wissenschaftlicher Werke durch Verlage als auch das Wissenschaftsurheberrecht stehen seit längerem in der Kritik. Die Open-Access-Bewegung tritt dafür ein, dass überwiegend öffentlich geförderte wissenschaftliche Ergebnisse frei im Internet verfügbar sein sollen. Die Implementierung dieses Ideals stößt aber auf erhebliche Beharrungskräfte. Deshalb gehen öffentliche Forschungsförderer vermehrt dazu über, Wissenschaftler zu Open-Access-Publikationen zu verpflichten. Der Beitrag skizziert die rechtlichen Maßnahmen, die ergriffen werden müssten, um Open Access zum Goldstandard der wissenschaftlichen Veröffentlichung zu küren. Ferner geht der Beitrag der Frage nach, ob ein solches Regelwerk Grundrechte der Verlage und der Wissenschaftler verletzen würde.
Der digitale Urheber
(2013)
Das dominante Rechtfertigungsnarrativ des kontinentaleuropäischen Urheberrechts ist der Schutz des kreativen Urhebers. Das diesbezügliche Leitbild ist der romantische Genius, der fern der Welt auf Hilfe durch Verwerter und einen starken Schutz seines „geistigen Eigentums“ in ihren Händen angewiesen ist. Im digitalen Zeitalter ist jedoch ein neuer Typus des Urhebers hervorgetreten: der digitale Urheber. Ihre Inspirationsquelle und zugleich ihr unternehmerisches Verbreitungs- und Vermarktungsmedium ist das globale Netz. Der Beitrag erörtert, welche Konsequenzen sich insbesondere für das Urhebervertragsrecht ergeben, wenn das Leitbild des digitalen Urhebers an die Stelle des romantischen/analogen Urhebers tritt.
Wie ersichtlich gehört Saiko zu jener Schriftstellergeneration der Zwischenkriegszeit, deren Jugendjahre in die Zeit vor dem Ersten Weltkrieg fallen. Mit seiner Romandarstellung unterscheidet er sich trotz der prinzipiellen Ähnlichkeiten in wichtigen Punkten von seinen Zeitgenossen. Diese Details werden von Klaus Kastberger in seinem Artikel Einsam auf dem Floß. Wohin treibt George Saiko (Kastberger 2003: 9) in folgenderweise hervorgehoben: Obwohl die Autoren Robert Musil, Franz Kafka und James Joyce oftmals Bezugsautoren für George Saiko bildeten, grenzt Saiko sich in den wichtigsten Einzelheiten von ihnen ab, denn wie Kastberger auch erwähnt, wird alles, was in die Figuren 'hineingepackt' ist, im Laufe der Darstellung erzählerisch 'ausgepackt'. Treffender lässt es sich sagen, George Saiko hätte nicht wie Musil, Kafka und Joyce geschrieben, sondern er versucht in seinem Roman Auf dem Floß (Saiko 1980), ein Seelenpanorama der Hauptfigur zu zeichnen. Mit dem Leitgedanken der Freudschen Theorien schildert Saiko eine andere Realität und zeichnet sie in seinen Romanen nach. Das Aufschließen der menschlichen Seele, die Gründe und Abgründe des menschlichen Verhaltens werden anhand von Saikos Romancharakteren ans Licht gebracht. In seinem Roman wird der Zerfall anhand menschlicher Triebe dargestellt.
Der Aufbau des zweiten Romans der Braunschweiger Trilogie "Stopfkuchen" gründet sich auf eine Zweipoligkeit, die durch das Gegenüberstellen des Romanhelden Heinrich Schaumann und seines Gegenspielers Eduard entsteht. Diese zwei Figuren gehören gegensätzlichen Welten an. Dem Antagonisten wird nur ein Name gegeben, und zwar der Vorname: Eduard! Der Protagonist wird mit beiden Namen vorgestellt: Heinrich Schaumann! Der Name des Helden hat symbolische Bedeutung, wie man es oft bei Raabe findet: Schaumann ist der Mann, der schaut. So wird dieses Kennzeichen seiner Funktion gerecht. Der Held beobachtet etwas. Seine Beobachtungen gelten der Gesellschaft. Er beobachtet eine Gesellschaft, die er nicht gutheißt, in die er sich nicht integriert. Vom geographischen Standpunkt aus betrachtet: Der Held Schaumann ist einer der Einwohner des am Fuße des Berges Rote Schanze gelegenen Ortes namens Maiholzen.
[W]elche Rolle spielen […] Mythen in der Literatur? D.h. welche Funktionen sind mit der Rezeption von Mythen verknüpft? Diese allgemeine und einfache Fragestellung wird im Rahmen der vorliegenden Arbeit dahingehend präzisiert, dass die Bedeutungsgehalte der Mythenkomplexe in den beiden Nachkriegsromanen 'Hamlet oder Die lange Nacht nimmt ein Ende' (1946) von Alfred Döblin und 'Nekyia. Bericht eines Überlebenden' (1947) von Hans Erich Nossack auf ihre Affinität zum Geschlechteraspekt hin befragt werden. Dieser Ansatz bietet sich ganz besonders an, weil Mythen als Teil des kulturellen Gedächtnisses und somit als kulturelle Repräsentationsformen überhaupt Geschlechterverhältnisse sowie Geschlechterrollen mitprägen und demzufolge bei der Erzeugung der Geschlechterdifferenz mitbestimmend werden. Diese beiden Romane behandeln zunächst zeitgeschichtliche Problemfelder, d.h. sie setzen sich primär mit der Kriegs- bzw. Schuldfrage auseinander. Allerdings erfährt diese Fragestellung eine tiefgreifende Transformation, denn bemerkenswerterweise werden hier mithilfe der Rezeption von bestimmten Mythenkomplexen Geschlechterdiskurse, genauer Weiblichkeitsdiskurse zum Tragen gebracht, die der anfänglichen Thematik von Krieg und Schuld einen gänzlich anderen Akzent verleihen.
Im Folgenden soll es zunächst darum gehen, den Mythos aus kulturwissenschaftlicher sowie mythostheoretischer Perspektive einzuordnen. Anschließend werde ich mich auf die Analyse der genannten Romane konzentrieren.
Zur Übersetzung literarischer Titel : Titelübersetzungen aus sprachwissenschaftlicher Perspektive
(2013)
Literarische Titel dienen nicht nur zur Identifizierung und Anpreisung eines Werkes, sondern sie geben oftmals auch direkte Hinweise zur Aufschlüsselung des Geschehens, des Themas oder des Werksinnes, ehe noch eine Aufklärung des Lesers durch den Text stattgefunden hat (vgl. Hellwig 1984: 6, Lämmert 1993: 144 u. Schweikle 1990: 465). Bei der Wahl der Überschrift für sein Werk zeigt der Autor daher größte Sorgfalt, um die Bedeutung und Aussagekraft zu intensivieren. Auch bei der Titelübersetzung sind diese Aspekte zu berücksichtigen. Die Übersetzungen von literarischen Titeln werden jedoch meist kritisiert, weil sie angeblich dem Original nicht entsprechen (vgl. Tanış Polat 2007a: 580ff.). Das Ziel der vorliegenden Studie besteht darin, anhand einer qualitativen und quantitativen Analyse Titelstrukturen nach Form, Frequenz und Distribution zu untersuchen, um Aufschluss über besondere übersetzungsstrategische Entscheidungen bei Werken der zeitgenössischen Literatur zu liefern und auf diese Weise mit einer wissenschaftlichen Argumentation der erwähnten Kritik entgegen zu treten. Der Beitrag ist folgendermaßen strukturiert: zunächst werden relevante Eigenschaften der literarischen Titel umrissen, danach folgt die Darstellung der Probleme, die die Titelübersetzung von literarischen Texten betrifft. Im Anschluss werden mit Hilfe einer Korpusanalyse, die sich auf übersetzte Titel aus dem Deutschen ins Türkische konzentriert, übersetzungsstrategische Entscheidungen untersucht. Die Analyse stützt sich auf die Gegenüberstellung von 270 zeitgenössischen Titeln. Mit einer Auswertung der Analyseergebnisse wird die Untersuchung abgeschlossen.
Der Titel dieses Beitrags variiert den berühmten Titel eines der Hauptwerke Nietzsches "Also sprach Zarathrustra". In seiner englischen Übersetzung lautet der Titel meist wie folgt: "Thus spoke (spake) Zarathrustra". Thus kennzeichnet Konklusivität, eine Schlussfolgerung aus einem zuvor genannten Umstand oder Sachverhalt. Das englische also, in seiner Schreibung dem deutschen also identisch, beinhaltet semantisch keine Konklusivität, sondern drückt Additivität aus. Der formgleiche Konnektor ist also (!) semantisch unterschiedlich im Deutschen und Englischen. Um diesen Unterschied und seine Bedeutung für türkische DaF-Lerner soll es im folgenden Artikel gehen.
Seit dem Einzug der digitalen Netzwerktechnologie ist das Urheberrecht zu einem heftig umkämpften Politikum geworden. Dies gilt auch im Hinblick auf „Wissenschaft“ als urheberrechtlichen Schutzgegenstand. Ob das Verhältnis zwischen Urheberrecht und Wissenschaft allerdings überhaupt als problematisch erscheint und welche Lösungsansätze für einen ggf. wahrgenommenen Konflikt präferiert werden, hängt maßgeblich von der Perspektive ab. Der Beitrag unterscheidet insoweit eine urheberrechtliche von einer wissenschaftstheoretisch/-soziologischen Betrachtungsweise. Es zeigt sich, dass nur Letztere geeignet ist, den gegenwärtig stattfindenden, grundlegenden Wandel des wissenschaftlichen Kommunikationssystems zu erklären und adäquate Regulierungsvorschläge zu entwickeln.
Objectives Tumour recurrence of glioblastoma multiforme (GBM) after initial treatment with surgical resection, radiotherapy and chemotherapy is an inevitable phenomenon. This retrospective cohort study compared the efficacy of interstitial high dose rate brachytherapy (HDR-BRT), re-resection and sole dose dense temozolomide chemotherapy (ddTMZ) in the treatment of recurrent glioblastoma after initial surgery and radiochemotherapy.
Design Retropective cohort study.
Setting Primary level of care with two participating centres. The geographical location was central Germany.
Participants From January 2005 to December 2010, a total of 111 patients developed recurrent GBM after initial surgery and radiotherapy with concomitant temozolomide. The inclusion criteria were as follows: (1) histology-proven diagnosis of primary GBM (WHO grade 4), (2) primary treatment with resection and radiochemotherapy, and (3) tumour recurrence/progression.
Interventions This study compared retrospectively the efficacy of interstitial HDR-BRT, re-resection and ddTMZ alone in the treatment of recurrent glioblastoma.
Primary and secondary outcome measures Median survival, progression free survival and complication rate.
Results Median survival after salvage therapy of the recurrence was 37, 30 and 26 weeks, respectively. The HDR-BRT group did significantly better than both the reoperation (p<0.05) and the ddTMZ groups (p<0.05). Moderate to severe complications in the HDR-BRT, reoperation and sole chemotherapy groups occurred in 5/50 (10%), 4/36 (11%) and 9/25 (36%) cases, respectively.
Conclusions CT-guided interstitial HDR-BRT attained higher survival benefits in the management of recurrent glioblastoma after initial surgery and radiotherapy with concurrent temozolomide in comparison with the other treatment modalities. The low risk of complications of the HDR-BRT and the fact that it can be delivered percutaneously in local anaesthesia render it a promissing treatment option for selected patients which should be further evaluated.
Purpose: To correlate inflammatory and proangiogenic key cytokines from undiluted vitreous of treatment-naïve central retinal vein occlusion (CRVO) patients with SD-OCT parameters.
Methods: Thirty-five patients (age 71.1 years, 24 phakic, 30 nonischemic) underwent intravitreal combination therapy, including a single-site 23-gauge core vitrectomy. Twenty-eight samples from patients with idiopathic, non-uveitis floaterectomy served as controls. Interleukin 6 (IL-6), monocyte chemoattractant protein-1 (MCP-1), and vascular endothelial growth factor (VEGF-A) levels were correlated with the visual acuity (logMar), category of CRVO (ischemic or nonischemic) and morphologic parameters, such as central macular thickness-CMT, thickness of neurosensory retina-TNeuro, extent of serous retinal detachment-SRT and disintegrity of the IS/OS and others.
Results: The mean IL-6 was 64.7pg/ml (SD ± 115.8), MCP-1 1015.7 ( ± 970.1), and VEGF-A 278.4 ( ± 512.8), which was significantly higher than the control IL-6 6.2 ± 3.4pg/ml (P=0.06), MCP-1 253.2 ± 73.5 (P<0.0000001) and VEGF-A 7.0 ± 4.9 (P<0.0006). All cytokines correlated highly with one another (correlation coefficient r=0.82 for IL-6 and MCP-1; r=0.68 for Il-6 and VEGF-A; r=0.64 for MCP-1 and VEGF-A). IL-6 correlated significantly with CMT, TRT, SRT, dIS/OS, and dELM. MCP-1 correlated significantly with SRT, dIS/OS, and dELM. VEGF-A correlated not with changes in SD-OCT, while it had a trend to be higher in the ischemic versus the nonischemic CRVO group (P=0.09).
Conclusions: The inflammatory cytokines were more often correlated with morphologic changes assessed by SD-OCT, whereas VEGF-A did not correlate with CRVO-associated changes in SD-OCT. VEGF inhibition alone may not be sufficient in decreasing the inflammatory response in CRVO therapy.
The creation of entirely synthetically derived bone substitute materials which are as effective as autologous bone grafts is desirable. Osteogenesis involves the concerted action of several proteins within a signaling cascade. Hedgehog proteins act upstream of this cascade, inducing the expression of various bone morphogenetic proteins (BMPs) and promoting physiological bone healing. Therefore, the hypothesis that hedgehog signaling in bone defects improves bone healing more than BMP signaling alone was tested. Recombinant N-terminal sonic hedgehog protein (N-SHh), BMP-2 or a combination of the two was added to β-tricalcium phosphate (β-TCP) and 5-mm femoral midshaft defects in nude rats were filled with these composites. The defects were stabilized with mini-plates. After eight weeks, the animals were sacrificed and the femora were explanted. The radiological evaluation was followed by a three-point bending test and histological examination. BMP-2/β-TCP composites showed a trend of increased stiffness compared with the controls (β-TCP without protein). N-SHh/β-TCP composites had lower stiffness compared with the control group and the N-SHh/BMP-2/β-TCP composites also had lower average stiffness compared with the controls (all not significant). Histomorphometry, however, revealed abundant cartilage and bone core formation in the N-SHh-composite groups. The sum of the new cartilage and bone was highest in the combination group N-SHh/BMP-2 (not significant). The addition of N-SHh to bone substitute materials appears to delay bone healing at the applied concentration and observation time but also showed a trend for higher amounts of ossifying cartilage.
We present the case of an aphasic 77-year-old stroke patient with left distal M1 occlusion who received rt-PA for thrombolysis while on oral anticoagulant treatment with dabigatran (150 mg b.i.d.). Coagulation parameters were normal (thrombin time 20 s, aPTT 20 s, INR 1.08) and the patient improved from an NIHSS of 15 to 5 within 24 h with sonographic evidence of M1 recanalization. She did not develop intracranial bleeding complications but showed unusually large diffuse skin ecchymoses. In our report, we give an overview of all reported cases of thrombolysis under dabigatran anticoagulation and discuss the questions of medication adherence under novel oral anticoagulants (NOA) and the safety of NOA in terms of secondary intracerebral hemorrhage after stroke.
Background: The incidence of pulmonary failure in trauma patients is considered to be influenced by several factors such as liver injury. We intended to assess the association of various potential predictors of pulmonary failure following thoracic trauma and liver injury.
Methods: Records of 12,585 trauma patients documented in the TraumaRegister DGU® of the German Trauma Society were analyzed regarding the potential impact of concomitant liver injury on the incidence of pulmonary failure using uni- and multivariate analyses. Pulmonary failure was defined as pulmonary failure of ≥ 3 SOFA-score points for at least two days. Patients were subdivided according to their injury pattern into four groups: group 1: AIS thorax < 3; AIS liver < 3; group 2: AIS thorax ≥ 3; AIS liver < 3; group 3: AIS thorax < 3; AIS liver ≥ 3 and group 4: AIS thorax ≥ 3; AIS liver ≥ 3.
Results: Overall, 2643 (21%) developed pulmonary failure, 12% (n= 642) in group 1, 26% (n= 697) in group 2, 16% (n= 30) in group 3, and 36% (n= 188) in group 4. Factors independently associated with pulmonary failure included relevant lung injury, pre-existing medical conditions (PMC), sex, transfusion of more than 10 units of packed red blood cells (PRBC), Glasgow Coma Scale (GCS) ≤ 8, and the ISS. However, liver injury was not associated with an increased risk of pulmonary failure following severe trauma in our setting.
Conclusions: Specific factors, but not liver injury, were associated with an increased risk of pulmonary failure following trauma. Trauma surgeons should be aware of these factors for optimized intensive care treatment.
The 25S rRNA of yeast contains several base modifications in the functionally important regions. The enzymes responsible for most of these base modifications remained unknown. Recently, we identified Rrp8 as a methyltransferase involved in m1A645 modification of 25S rRNA. Here, we discovered a previously uncharacterized gene YBR141C to be responsible for second m1A2142 modification of helix 65 of 25S rRNA. The gene was identified by reversed phase–HPLC screening of all deletion mutants of putative RNA methyltransferase and was confirmed by gene complementation and phenotypic characterization. Because of the function of its encoded protein, YBR141C was named BMT2 (base methyltransferase of 25S RNA). Helix 65 belongs to domain IV, which accounts for most of the intersubunit surface of the large subunit. The 3D structure prediction of Bmt2 supported it to be an Ado Met methyltransferase belonging to Rossmann fold superfamily. In addition, we demonstrated that the substitution of G180R in the S-adenosyl-l-methionine–binding motif drastically reduces the catalytic function of the protein in vivo. Furthermore, we analysed the significance of m1A2142 modification in ribosome synthesis and translation. Intriguingly, the loss of m1A2142 modification confers anisomycin and peroxide sensitivity to the cells. Our results underline the importance of RNA modifications in cellular physiology.
In previous work we have documented the nuclear translocation of endothelial NOS (eNOS) and its participation in combinatorial complexes with Estrogen Receptor Beta (ERβ) and Hypoxia Inducible Factors (HIFs) that determine localized chromatin remodeling in response to estrogen (E2) and hypoxia stimuli, resulting in transcriptional regulation of genes associated with adverse prognosis in prostate cancer (PCa). To explore the role of nuclear eNOS in the acquisition of aggressive phenotype in PCa, we performed ChIP-Sequencing on chromatin-associated eNOS from cells from a primary tumor with poor outcome and from metastatic LNCaP cells. We found that: 1. the eNOS-bound regions (peaks) are widely distributed across the genome encompassing multiple transcription factors binding sites, including Estrogen Response Elements. 2. E2 increased the number of peaks, indicating hormone-dependent eNOS re-localization. 3. Peak distribution was similar with/without E2 with ≈ 55% of them in extragenic DNA regions and an intriguing involvement of the 5′ domain of several miRs deregulated in PCa. Numerous potentially novel eNOS-targeted genes have been identified suggesting that eNOS participates in the regulation of large gene sets. The parallel finding of downregulation of a cluster of miRs, including miR-34a, in PCa cells associated with poor outcome led us to unveil a molecular link between eNOS and SIRT1, an epigenetic regulator of aging and tumorigenicity, negatively regulated by miR-34a and in turn activating eNOS. E2 potentiates miR-34a downregulation thus enhancing SIRT1 expression, depicting a novel eNOS/SIRT1 interplay fine-tuned by E2-activated ER signaling, and suggesting that eNOS may play an important role in aggressive PCa.

Environmental change impacts on the C- and N-cycle of European forests: a model comparison study
(2013)
Forests are important components of the greenhouse gas balance of Europe. There is considerable uncertainty about how predicted changes to climate and nitrogen deposition will perturb the carbon and nitrogen cycles of European forests and thereby alter forest growth, carbon sequestration and N2O emission. The present study aimed to quantify the carbon and nitrogen balance, including the exchange of greenhouse gases, of European forests over the period 2010–2030, with a particular emphasis on the spatial variability of change. The analysis was carried out for two tree species: European beech and Scots pine. For this purpose, four different dynamic models were used: BASFOR, DailyDayCent, INTEGRATOR and Landscape-DNDC. These models span a range from semi-empirical to complex mechanistic. Comparison of these models allowed assessment of the extent to which model predictions depended on differences in model inputs and structure. We found a European average carbon sink of 0.160 ± 0.020 kgC m−2 yr−1 (pine) and 0.138 ± 0.062 kgC m−2 yr−1 (beech) and N2O source of 0.285 ± 0.125 kgN ha−1 yr−1 (pine) and 0.575 ± 0.105 kgN ha−1 yr−1 (beech). The European average greenhouse gas potential of the carbon sink was 18 (pine) and 8 (beech) times that of the N2O source. Carbon sequestration was larger in the trees than in the soil. Carbon sequestration and forest growth were largest in central Europe and lowest in northern Sweden and Finland, N. Poland and S. Spain. No single driver was found to dominate change across Europe. Forests were found to be most sensitive to change in environmental drivers where the drivers were limiting growth, where changes were particularly large or where changes acted in concert. The models disagreed as to which environmental changes were most significant for the geographical variation in forest growth and as to which tree species showed the largest rate of carbon sequestration. Pine and beech forests were found to have differing sensitivities to environmental change, in particular the response to changes in nitrogen and precipitation, with beech forest more vulnerable to drought. There was considerable uncertainty about the geographical location of N2O emissions. Two of the models BASFOR and LandscapeDNDC had largest emissions in central Europe where nitrogen deposition and soil nitrogen were largest, whereas the two other models identified different regions with large N2O emission. N2O emissions were found to be larger from beech than pine forests and were found to be particularly sensitive to forest growth.
In 'Mein Jenseits', der dritten Novelle innerhalb Walsers umfangreicher literarischer Produktion, werden uns von Walsers früheren Büchern bekannte Themen aus einer neuen, einem "Spätwerk" entsprechenden Perspektive dargeboten, wie im Laufe dieser Analyse gezeigt werden soll. In diesem Zusammenhang soll besonders die zentrale Rolle, die hier einem Bild für das Textganze zukommt, beleuchtet werden.
Wie bekannt, besitzt neben der literarischen Übersetzung auch die fachsprachliche Übertragung einen wichtigen Platz in der übersetzungswissenschaftlichen Forschung. In Rahmen des Themas Übersetzung und Bearbeitung soll in diesem Beitrag festgestellt werden, welche satzstrukturelle Abwandlungen das neue Strafgesetzbuch der Türkei (YTCK) vollzogen hat.
Einen Witz oder eben auch eine Geschichte gut zu erzählen ist ein risikoreiches Unterfangen und verlangt nach bestimmten Kompetenzen. Literaturwissenschaftliche wie auch sprach- und übersetzungswissenschaftliche Beiträge haben sich mit dem Erzählen beschäftigt, und das Fazit scheint berechtigt, Erzähltexte als Schnittstelle fachlicher Entwicklungen anzusehen. Sie erweisen sich als besonders günstige Anschlussstelle für Fragestellungen, die intradisziplinäre Grenzziehungen überschreiten. Dies soll in der folgenden kleinen Skizze aus linguistischer Sicht genauer entfaltet werden.
Ortak ve Suni dil üzerine
(2013)
Ortak ve Suni dilin ayrıştığı nokta bir toplum içerisinde bireylerin sağlıklı iletişim kuramamaları sonucu birbirlerini anlamadıkları ve iletişimin abartılı bir durumda değerlendirilmesidir. Bireyler arasında sağlıklı iletişimin sağlanması, aralarında ihtilafın giderilmesi gibi konular dilbilimcilerin başlıca araştırma alanlarını oluşturmaktadır. Diğer bir ifade ile yapay dil ile ortak bir dilin amaçlanması, geliştirilmesi 16.y.y. dan itibaren günümüze değin sürdürülmüştür. Ne var ki konuyu sadece art zamanlı olarak değerlendirmek yerine, aynı toplum içerisinde eş zamanlı olarak nasıl irdelenebilir? Zira ortak dilin "evrensel" bir dil olduğu varsayımından hareketle aynı toplum içerisinde, iletişimin genellikle "yapay" bir dille gerçekleştiği savını da öne sürebiliriz. Bir toplum içerisinde ortak dile ulaşmanın yolu analiz-sentez yolu ile kavrama kültürünün doğru orantılı olmasıdır.
DEAD box helicases catalyze the ATP-dependent destabilization of RNA duplexes. Whereas duplex separation is mediated by the helicase core shared by all members of the family, flanking domains often contribute to binding of the RNA substrate. The Thermus thermophilus DEAD-box helicase Hera (for “heat-resistant RNA-binding ATPase”) contains a C-terminal RNA-binding domain (RBD). We have analyzed RNA binding to the Hera RBD by a combination of mutational analyses, nuclear magnetic resonance and X-ray crystallography, and identify residues on helix α1 and the C-terminus as the main determinants for high-affinity RNA binding. A crystal structure of the RBD in complex with a single-stranded RNA resolves the RNA–protein interactions in the RBD core region around helix α1. Differences in RNA binding to the Hera RBD and to the structurally similar RBD of the Bacillus subtilis DEAD box helicase YxiN illustrate the versatility of RNA recognition motifs as RNA-binding platforms. Comparison of chemical shift perturbation patterns elicited by different RNAs, and the effect of sequence changes in the RNA on binding and unwinding show that the RBD binds a single-stranded RNA region at the core and simultaneously contacts double-stranded RNA through its C-terminal tail. The helicase core then unwinds an adjacent RNA duplex. Overall, the mode of RNA binding by Hera is consistent with a possible function as a general RNA chaperone.
When studying new particle formation, the uncertainty in determining the "true" nucleation rate is considerably reduced when using Condensation Particle Counters (CPCs) capable of measuring concentrations of aerosol particles at sizes close to or even at the critical cluster size (1–2 nm). Recently CPCs, able to reliably detect particles below 2 nm in size and even close to 1 nm became available. The corrections needed to calculate nucleation rates are substantially reduced compared to scaling the observed formation rate to the nucleation rate at the critical cluster size. However, this improved instrumentation requires a careful characterization of their cut-off size and the shape of the detection efficiency curve because relatively small shifts in the cut-off size can translate into larger relative errors when measuring particles close to the cut-off size.
Here we describe the development of two continuous flow CPCs using diethylene glycol (DEG) as the working fluid. The design is based on two TSI 3776 counters. Several sets of measurements to characterize their performance at different temperature settings were carried out. Furthermore two mixing-type Particle Size Magnifiers (PSM) A09 from Airmodus were characterized in parallel. One PSM was operated at the highest mixing ratio (1 L min−1 saturator flow), and the other was operated in a scanning mode, where the mixing ratios are changed periodically, resulting in a range of cut-off sizes. Different test aerosols were generated using a nano-Differential Mobility Analyzer (nano-DMA) or a high resolution DMA, to obtain detection efficiency curves for all four CPCs. One calibration setup included a high resolution mass spectrometer (APi-TOF) for the determination of the chemical composition of the generated clusters. The lowest cut-off sizes were achieved with negatively charged ammonium sulphate clusters, resulting in cut-offs of 1.4 nm for the laminar flow CPCs and 1.2 and 1.1 nm for the PSMs. A comparison of one of the laminar-flow CPCs and one of the PSMs measuring ambient and laboratory air showed good agreement between the instruments.
The SAWNUC microphysical aerosol nucleation model is used to study the effect of reactor walls on the interpretation of nucleation experiments with respect to nucleation theory. This work shows that loss processes, such as wall losses, influence the interpretation of nucleation experiments, especially at low growth rates and short lifetime of freshly nucleated particles. In these cases the power dependency of the formation rates, determined at a certain particle size, with respect to H2SO4 does not correspond to the approximate number of H2SO4 molecules in the critical cluster as expected by the first nucleation theorem. Observed ∂log(J)/∂log([H2SO4]) therefore can vary widely for identical nucleation conditions but different sink terms.
We investigate the contribution of oceanic methyl iodide (CH3I) to the stratospheric iodine budget. Based on CH3I measurements during three tropical ship campaigns and the Lagrangian transport model FLEXPART we provide a detailed analysis of CH3I transport from the ocean surface to the cold point in the upper tropical tropopause layer (TTL). While average oceanic emissions differ by less than 50% from campaign to campaign, the measurements show much stronger variations within each campaign. A positive correlation between the oceanic CH3I emissions and the efficiency of CH3I troposphere–stratosphere transport has been identified for some cruise sections. The mechanism of strong horizontal surface winds triggering large emissions on the one hand and being associated with tropical convective systems, such as developing typhoons, on the other hand, could explain the identified correlations. As a result of the simultaneous occurrence of large CH3I emissions and strong vertical uplift, localized maximum mixing ratios of 0.6 ppt CH3I at the cold point have been determined for observed peak emissions during the SHIVA-Sonne campaign in the coastal West Pacific. The other two campaigns give considerable smaller maxima of 0.1 ppt CH3I for the TransBrom campaign in the open West Pacific and 0.03 ppt for emissions from the coastal East Atlantic during the DRIVE campaign. In order to assess the representativeness of the large local mixing ratios we use climatological emission scenarios to derive global upper air estimates of CH3I abundances. The model results are compared to available upper air measurements including data from the recent ATTREX and HIPPO2 aircraft campaigns. In the East Pacific region, the location of the available measurement campaigns in the upper TTL, the comparisons give a good agreement indicating that around 0.01 to 0.02 ppt of CH3I enter the stratosphere. However, other tropical regions, which are subject to stronger convective activity show larger CH3I entrainment, e.g., 0.08 ppt in the West Pacific. The strong variations in the geographical distribution of CH3I entrainment suggest that currently available upper air measurements are not representative of global estimates and further campaigns will be necessary in order to better understand the CH3I contribution to stratospheric iodine.
Tropical forest soils are a significant source for the greenhouse gas N2O as well as for NO, a precursor of tropospheric ozone. However, current estimates are uncertain due to the limited number of field measurements. Furthermore, there is considerable spatial and temporal variability of N2O and NO emissions due to the variation of environmental conditions such as soil properties, vegetation characteristics and meteorology. In this study we used a process-based model (ForestDNDC-tropica) to estimate N2O and NO emissions from tropical highland forest (Nyungwe) soils in southwestern Rwanda. To extend the model inputs to regional scale, ForestDNDC-tropica was linked to an exceptionally large legacy soil dataset. There was agreement between N2O and NO measurements and the model predictions though the ForestDNDC-tropica resulted in considerable lower emissions for few sites. Low similarity was specifically found for acidic soil with high clay content and reduced metals, indicating that chemo-denitrification processes on acidic soils might be under-represented in the current ForestDNDC-tropica model. The results showed that soil bulk density and pH are the most influential factors driving spatial variations in soil N2O and NO emissions for tropical forest soils. The area investigated (1113 km2) was estimated to emit ca. 439 ± 50 t N2O-N yr−1 (2.8–5.5 kg N2O-N ha−1 yr−1) and 244 ± 16 t NO-N yr−1 (0.8–5.1 kg N ha−1 yr−1). Consistent with less detailed studies, we confirm that tropical highland rainforest soils are a major source of atmospheric N2O and NO.
Water footprints have been proposed as sustainability indicators, relating the consumption of goods like food to the amount of water necessary for their production and the impacts of that water use in the source regions. We have further developed the existing water footprint methodology by globally resolving virtual water flows and import and source regions at 5 arc minutes spatial resolution, and by assessing local impacts of export production. Applying this method to three exemplary cities, Berlin, Delhi and Lagos, we find major differences in amounts, composition, and origin of green and blue virtual water imports, due to differences in diets, trade integration and crop water productivities in the source regions. While almost all of Delhi's and Lagos' virtual water imports are of domestic origin, Berlin on average imports from more than 4000 km distance, in particular soy (livestock feed), coffee and cocoa. While 42% of Delhi's virtual water imports are blue water based, the fractions for Berlin and Lagos are 2% and 0.5%, respectively, roughly equal to local drinking water abstractions of these cities. Some of the external source regions of Berlin's virtual water imports appear to be critically water scarce and/or food insecure. However for deriving recommendations on sustainable consumption and trade, further analysis of context-specific costs and benefits associated with export production will be required.
Estimates of the recovery time of stratospheric ozone heavily rely on the exact knowledge of the processes that lead to the decomposition of the relevant halogenated source gases. Crucial parameters in this context are fractional release factors (FRFs) as well as stratospheric lifetimes and ozone depletion potentials (ODPs). We here present data from the analysis of air samples collected between 2009 and 2011 on board research aircraft flying in the mid- and high-latitude stratosphere and infer the above-mentioned parameters for ten major source gases: CFCl3 (CFC-11), CF2Cl2 (CFC-12), CF2ClCFCl2 (CFC-113), CCl4 (carbon tetrachloride), CH3CCl3 (methyl chloroform), CHF2Cl (HCFC-22), CH3CFCl2 (HCFC-141b), CH3CF2Cl (HCFC-142b), CF2ClBr (H-1211), and CF3Br (H-1301). The inferred correlations of their FRFs with mean ages of air reveal less decomposition as compared to previous studies for most compounds. When using the calculated set of FRFs to infer equivalent stratospheric chlorine, we find a reduction of more than 20% as compared to the values inferred in the most recent Scientific Assessment of Ozone Depletion by the World Meteorological Organisation (WMO, 2011). We also note that FRFs and their correlations with mean age are not generally time-independent as often assumed. The stratospheric lifetimes were calculated relative to that of CFC-11. Within our uncertainties the ratios between stratospheric lifetimes inferred here agree with the values in recent WMO reports except for CFC-11, CFC-12 and CH3CCl3. Finally, we calculate lower ODPs than recommended by WMO for six out of ten compounds, with changes most pronounced for the three HCFCs. Collectively these newly calculated values may have important implications for the severity and recovery time of stratospheric ozone loss.
Aboveground and belowground biomass compartments of vegetation fulfil different functions and they are coupled by complex interactions. These compartments exchange water, carbon and nutrients and the belowground biomass compartment has the capacity to buffer vegetation dynamics when aboveground biomass is removed by disturbances such as herbivory or fire. However, despite their importance, root-shoot interactions are often ignored in more heuristic vegetation models. Here, we present a simple two-compartment grassland model that couples aboveground and belowground biomass. In this model, the growth of belowground biomass is influenced by aboveground biomass and the growth of aboveground biomass is influenced by belowground biomass. We used the model to explore how the dynamics of a grassland ecosystem are influenced by fire and grazing. We show that the grassland system is most persistent at intermediate levels of aboveground-belowground coupling. In this situation, the system can sustain more extreme fire or grazing regimes than in the case of strong coupling. In contrast, the productivity of the system is maximised at high levels of coupling. Our analysis suggests that the yield of a grassland ecosystem is maximised when coupling is strong, however, the intensity of disturbance that can be sustained increases dramatically when coupling is intermediate. Hence, the model predicts that intermediate coupling should be selected for as it maximises the chances of persistence in disturbance driven ecosystems.
Accurate multidimensional localization of isolated fluorescent emitters is a time consuming process in single-molecule based super-resolution microscopy. We demonstrate a functional method for real-time reconstruction with automatic feedback control, without compromising the localization accuracy. Compatible with high frame rates of EM-CCD cameras, it relies on a wavelet segmentation algorithm, together with a mix of CPU/GPU implementation. A combination with Gaussian fitting allows direct access to 3D localization. Automatic feedback control ensures optimal molecule density throughout the acquisition process. With this method, we significantly improve the efficiency and feasibility of localization-based super-resolution microscopy.
