Vom klassischen Film zur Zweiten Moderne : Überlegungen zur Differenz von Bild und Ton im Film
(2008)
Michel Chion, einer der wichtigsten Filmtontheoretiker der Gegenwart, geht in seinem Werk L´audio-vision (1990) davon aus, dass Bild und Ton hinsichtlich eines „audiovisuellen Kontrakts“ zwar keine natürliche Beziehung zueinander unterhalten, der Rezipient jedoch eine symbolische Beziehung zwischen beiden sieht, die aus Bild und Ton eine Einheit werden lässt. In der Filmtheorie steht diesem synthetisierenden Modell von Akustischem und Visuellem ein differentieller Denkansatz entgegen, der das audiovisuelle Zusammenspiel im Film nicht als Synthese, sondern als Kräftefeld unterschiedlicher Bestandteile begreift, die zwar einen Bezug zueinander haben, aber dennoch technisch wie ästhetisch getrennt und heterogen sind.
Alan Croslands Film THE JAZZ SINGER wird in zahlreichen wissenschaftlichen Abhandlungen zum Übergang vom Stumm- zum Tonfilm als der Film beschrieben, der dem Tonfilm endgültig zum Durchbruch verhalf (vgl. Dibbets 1998, 197; Nowell-Smith 1998, 193; Henzel 2006, 47). Doch obwohl THE JAZZ SINGER maßgeblich dazu beigetragen hat, das neue Medium Tonfilm am Markt zu etablieren, handelt es sich bei diesem Film nicht um den ersten Tonfilm, wie gelegentlich behauptet wird (vgl. Ferrari 2004, 70), sondern lediglich um einen „Stummfilm mit einigen vertonten Einschüben“ (Dibbets 1998, 197). THE JAZZ SINGER ist ein so genannter part-talkie, ein Film also, der nur zum Teil vertont wurde. An ausgewählten Stellen enthält er „lippensynchrone Lieder und Dialog“ (Dibbets 1998, 197). Das expressive Spiel der Figuren und der Einsatz von Zwischentiteln hingegen erinnern an den Stummfilm. Doch nicht nur die Tatsache, dass THE JAZZ SINGER kein hundertprozentiger Tonfilm ist, steht laut Christoph Henzel einer Definition als erstem Tonfilm entgegen. Darüber hinaus ist er auch nicht der erste Film, der technisch in der Lage war, Bild und Ton zu synchronisieren. Vielmehr positioniert er sich als ein Ereignis unter vielen, als ein Glied innerhalb einer ganzen Reihe technischer Entwicklungen vom Stumm- zum Tonfilm (vgl. Henzel 2006, 48/49).
Einen wesentlichen Einfluss auf die Ästhetik des cinéma vérité hatte die Entwicklung tontauglicher Handkameras, die den Filmemachern die ästhetische Möglichkeit einer Manipulation und Differenz (im Sinne einer bewussten, eingreifenden Dissoziation und Disjunktion) von Akustischem und Visuellem eröffnete. Anhand ausgewählter Szenen von CHRONIQUE D’UN ÉTÉ möchte ich im Folgenden zeigen, wie sich diese Bewegung auf ästhetischer Ebene darstellt. Im Mittelpunkt soll der Akt des Offenlegens und Reflektierens des filmischen Schaffensprozesses stehen, der als wesentlicher Aspekt filmischer Modernität bezeichnet werden kann. Zu weiten Teilen folge ich dabei den Schriften von Jean-Louis Comolli und Gilles Deleuze, insbesondere was die prominent beschriebene Durchdringung von dokumentarischem und fiktionalem Stil betrifft, die sich in CHRONIQUE D’UN ÉTÉ nicht nur auf bildlicher, sondern auch und gerade – und das ist das Wesentliche an meiner Argumentation – auf akustischer Ebene nachweisen lässt.
The Infectious Diseases Working Party (AGIHO) of the German Society of Hematology and Oncology (DGHO) here presents its updated recommendations for the treatment of documented fungal infections. Invasive fungal infections are a main cause of morbidity and mortality in cancer patients undergoing intensive chemotherapy regimens. In recent years, new antifungal agents have been licensed, and agents already approved have been studied in new indications. The choice of the most appropriate antifungal treatment depends on the fungal species suspected or identified, the patient’s risk factors (e.g., length and depth of neutropenia), and the expected side effects. This guideline reviews the clinical studies that served as a basis for the following recommendations. All recommendations including the levels of evidence are summarized in tables to give the reader rapid access to the information.
An increasing body of evidences from preclinical as well as epidemiological and clinical studies suggest a potential beneficial role of dietary intake of omega-3 fatty acids for cognitive functioning. In this narrative review, we will summarize and discuss recent findings from epidemiological, interventional and experimental studies linking dietary consumption of omega-3 fatty acids to cognitive function in healthy adults. Furthermore, affective disorders and schizophrenia (SZ) are characterized by cognitive dysfunction encompassing several domains. Cognitive dysfunction is closely related to impaired functioning and quality of life across these conditions. Therefore, the current review focues on the potential influence of omega-3 fatty acids on cognition in SZ and affective disorders. In sum, current data predominantly from mechanistic models and animal studies suggest that adjunctive omega-3 fatty acid supplementation could lead to improved cognitive functioning in SZ and affective disorders. However, besides its translational promise, evidence for clinical benefits in humans has been mixed. Notwithstanding evidences indicate that adjunctive omega-3 fatty acids may have benefit for affective symptoms in both unipolar and bipolar depression, to date no randomized controlled trial had evaluated omega-3 as cognitive enhancer for mood disorders, while a single published controlled trial suggested no therapeutic benefit for cognitive improvement in SZ. Considering the pleiotropic mechanisms of action of omega-3 fatty acids, the design of well-designed controlled trials of omega-3 supplementation as a novel, domain-specific, target for cognitive impairment in SZ and affective disorders is warranted.
Latent transforming growth factor beta binding protein 4 (LTBP4) belongs to the fibrillin/LTBP family of proteins and plays an important role as a structural component of extracellular matrix (ECM) and local regulator of TGFβ signaling. We have previously reported that Ltbp4S knock out mice (Ltbp4S −/−) develop centrilobular emphysema reminiscent of late stage COPD, which could be partially rescued by inactivating the antioxidant protein Sestrin 2 (Sesn2). More recent studies showed that Sesn2 knock out mice upregulate Pdgfrβ-controlled alveolar maintenance programs that protect against cigarette smoke induced pulmonary emphysema. Based on this, we hypothesized that the emphysema of Ltbp4S −/− mice is primarily caused by defective Pdgfrβ signaling. Here we show that LTBP4 induces Pdgfrβ signaling by inhibiting the antioxidant Nrf2/Keap1 pathway in a TGFβ-dependent manner. Overall, our data identified Ltbp4 as a major player in lung remodeling and injury repair.
Background: Although mortality after cardiac surgery has significantly decreased in the last decade, patients still experience clinically relevant postoperative complications. Among others, atrial fibrillation (AF) is a common consequence of cardiac surgery, which is associated with prolonged hospitalization and increased mortality.
Methods: We retrospectively analyzed data from patients who underwent coronary artery bypass grafting, valve surgery or a combination of both at the University Hospital Muenster between April 2014 and July 2015. We evaluated the incidence of new onset and intermittent/permanent AF (patients with pre- and postoperative AF). Furthermore, we investigated the impact of postoperative AF on clinical outcomes and evaluated potential risk factors.
Results: In total, 999 patients were included in the analysis. New onset AF occurred in 24.9% of the patients and the incidence of intermittent/permanent AF was 59.5%. Both types of postoperative AF were associated with prolonged ICU length of stay (median increase approx. 2 days) and duration of mechanical ventilation (median increase 1 h). Additionally, new onset AF patients had a higher rate of dialysis and hospital mortality and more positive fluid balance on the day of surgery and postoperative days 1 and 2. In a multiple logistic regression model, advanced age (odds ratio (OR) = 1.448 per decade increase, p < 0.0001), a combination of CABG and valve surgery (OR = 1.711, p = 0.047), higher C-reactive protein (OR = 1.06 per unit increase, p < 0.0001) and creatinine plasma concentration (OR = 1.287 per unit increase, p = 0.032) significantly predicted new onset AF. Higher Horowitz index values were associated with a reduced risk (OR = 0.996 per unit increase, p = 0.012). In a separate model, higher plasma creatinine concentration (OR = 2.125 per unit increase, p = 0.022) was a significant risk factor for intermittent/permanent AF whereas higher plasma phosphate concentration (OR = 0.522 per unit increase, p = 0.003) indicated reduced occurrence of this arrhythmia.
Conclusions: New onset and intermittent/permanent AF are associated with adverse clinical outcomes of elective cardiac surgery patients. Different risk factors implicated in postoperative AF suggest different mechanisms might be involved in its pathogenesis. Customized clinical management protocols seem to be warranted for a higher success rate of prevention and treatment of postoperative AF.
During the Late Cretaceous and early Cenozoic the Earth experienced prolonged climatic cooling most likely caused by decreasing volcanic activity and atmospheric CO2 levels. However, the causes and mechanisms of subsequent major global warming culminating in the late Paleocene to Eocene greenhouse climate remain enigmatic. We present deep and intermediate water Nd-isotope records from the North and South Atlantic to decipher the control of the opening Atlantic Ocean on ocean circulation and its linkages to the evolution of global climate. The marked convergence of Nd-isotope signatures 59 million years ago indicates a major intensification of deep-water exchange between the North and South Atlantic, which coincided with the turning point of deep-water temperatures towards early Paleogene warming. We propose that this intensification of Atlantic overturning circulation in concert with increased atmospheric CO2 from continental rifting marked a climatic tipping point contributing to a more efficient distribution of heat over the planet.
Pseudomonas aeruginosa is a human pathogen that causes health-care associated blood stream infections (BSI). Although P. aeruginosa BSI are associated with high mortality rates, the clinical relevance of pathogen-derived prognostic biomarker to identify patients at risk for unfavorable outcome remains largely unexplored. We found novel pathogen-derived prognostic biomarker candidates by applying a multi-omics approach on a multicenter sepsis patient cohort. Multi-level Cox regression was used to investigate the relation between patient characteristics and pathogen features (2298 accessory genes, 1078 core protein levels, 107 parsimony-informative variations in reported virulence factors) with 30-day mortality. Our analysis revealed that presence of the helP gene encoding a putative DEAD-box helicase was independently associated with a fatal outcome (hazard ratio 2.01, p = 0.05). helP is located within a region related to the pathogenicity island PAPI-1 in close proximity to a pil gene cluster, which has been associated with horizontal gene transfer. Besides helP, elevated protein levels of the bacterial flagellum protein FliL (hazard ratio 3.44, p < 0.001) and of a bacterioferritin-like protein (hazard ratio 1.74, p = 0.003) increased the risk of death, while high protein levels of a putative aminotransferase were associated with an improved outcome (hazard ratio 0.12, p < 0.001). The prognostic potential of biomarker candidates and clinical factors was confirmed with different machine learning approaches using training and hold-out datasets. The helP genotype appeared the most attractive biomarker for clinical risk stratification due to its relevant predictive power and ease of detection.
