Eine Stadttour durch Hamburg im Jahr 1686: die App Hidden Hamburg als erlebbare Geschichte und Digital-Public-History-Experiment

Mit der App Hidden Hamburg liegt ein kostenloses und zweisprachiges An­ge­bot zu einer Stadttour im Hamburg des Jahres 1686 vor. Die App ist ein digita­les Experiment, das historisches story telling als „erlebbare Geschich­te“ mal anders akzentuiert: bequem am Computer-Bildschirm daheim oder als echte Stadttour durch Hamburg mit GPS-Tracking und einem Smartphone. In diesem Begleitbuch, das mit didaktischen Hinweisen, vertiefenden The­men­inseln und stadthistorischen Einordnungen für den Einsatz in Klassen­zim­mern und Seminarräumen ebenso geeignet ist wie für den Museums­be­such, werden die Ideen und Kontexte der vorbereiteten Stadttour beleuchtet. Rund um den virtuellen Stadtführer Johann, der in der Nach­rich­ten­hochburg Hamburg im Jahr 1686 lebt, bietet dieses reich bebilderte Begleitbuch neue Einblicke in das frühneuzeitliche Hamburg als eine „Stadt der Neuigkeiten“, bekannt für ihre vielen Druckereien, stete Publizistik-Herstellung und Fülle an medialen Echos. Dieses Buch führt zu Buchhandlungen in Kirchen, zu Zeitungsständen auf Marktplätzen, in ein Kaffeehaus, zum Opernhaus, und bietet in Kombina­tion mit App und Webseite (www.hiddencities.eu) einen alternativen Einstieg in Mediengeschichte, Stadtgeschichte und Pressegeschichte. Viele integrierte Mu­seumsobjekte aus Hamburg, u.a. aus dem Museum für Ham­burgische Ge­schich­te, vermitteln einen lebendigen Eindruck von Hamburg vor rund 350 Jahren

Metaphor Identification beyond Discourse Coherence

In this paper, we propose an account of metaphor identification on the basis of contextual coherence. In doing so, we build on previous work by Nicholas Asher and Alex Lascarides that appeals to rhetorical relations in order to explain discourse structure and the constraints on the interpretation of metaphor that follow from it. Applying this general idea to our problem, we will show that rhetorical relations are sometimes insufficient and sometimes inadequate for deciding whether a given utterance is a case of metaphor. They are insufficient, since rhetorical relations fall short at times of providing a basis for disambiguating between literal and metaphorical interpretations. In such cases, contextual information other than previous discourse needs to enter the picture. To this effect, we bring the idea of external consistency into play. Beyond that, though, we will argue that rhetorical relations are sometimes inadequate to account for coherence, if conceived as relations among sentences only. The reason is that extra-linguistic elements of the situation in which the sentence is uttered may be crucial for getting at the preferred interpretation. To account for these cases, we allow rhetorical relations to connect both with previous discourse and with extra-linguistic situations. In our final refinement of the notion of contextual coherence, we forfeit any appeal to rhetorical relations in favour of Questions Under Discussion (QUD). We defend the view that this account does not only explain the same sort of cases. What is more, it solves the issue of metaphor identification in impoverished contexts

A randomized controlled trial

Objective We report on the effect of hemoadsorption therapy to reduce cytokines in septic patients with respiratory failure. Methods This was a randomized, controlled, open-label, multicenter trial. Mechanically ventilated patients with severe sepsis or septic shock and acute lung injury or acute respiratory distress syndrome were eligible for study inclusion. Patients were randomly assigned to either therapy with CytoSorb hemoperfusion for 6 hours per day for up to 7 consecutive days (treatment), or no hemoperfusion (control). Primary outcome was change in normalized IL-6-serum concentrations during study day 1 and 7. Results 97 of the 100 randomized patients were analyzed. We were not able to detect differences in systemic plasma IL-6 levels between the two groups (n = 75; p = 0.15). Significant IL-6 elimination, averaging between 5 and 18% per blood pass throughout the entire treatment period was recorded. In the unadjusted analysis, 60-day-mortality was significantly higher in the treatment group (44.7%) compared to the control group (26.0%; p = 0.039). The proportion of patients receiving renal replacement therapy at the time of enrollment was higher in the treatment group (31.9%) when compared to the control group (16.3%). After adjustment for patient morbidity and baseline imbalances, no association of hemoperfusion with mortality was found (p = 0.19). Conclusions In this patient population with predominantly septic shock and multiple organ failure, hemoadsorption removed IL-6 but this did not lead to lower plasma IL-6-levels. We did not detect statistically significant differences in the secondary outcomes multiple organ dysfunction score, ventilation time and time course of oxygenation

Polyesters with main and side chain phosphoesters as structural motives for biocompatible electrospun fibres

Phosphoester containing polymers are promising materials in biomedical applications due to their biocompatibility and biodegradability. Utilising thiol-ene chemistry, the synthesis of two novel structural polymer motives combining polyesters and phophoester groups was explored. The first polymer was obtained by coupling ene-functional poly(thioether-phosphoester) with thiol functional poly(pentadecalactone). While the coupling reaction was successful, yields remained low presumably due to inadequate endgroup stoichiometry. The second polymer comprised phosphoester side groups conjugated to unsaturated poly(globalide). Double bond conversions up to 84% were achieved depending of the type of phosphoester thiol and relative reactant ratios. The resulting polymers transitioned from solid semicrystaline to liquid amorphous with increasing degree of phosphoester conjugation. Electrospun fibres from polymers with 14% phosphoester conjugation allowed attachment and survival of human dermal fibroblasts, indicating their biocompatibility. These polymers represent a new class of easily accessible biocompatible polyester-phosphoester hybrid materials as potential building blocks for tunable biomaterials

Integrative medicine during the intensive phase of chemotherapy in pediatric oncology in Germany: a randomized controlled trial with 5-year follow up

Background: Integrative medicine is used frequently alongside chemotherapy treatment in pediatric oncology, but little is known about the influence on toxicity. This German, multi-center, open-label, randomized controlled trial assessed the effects of complementary treatments on toxicity related to intensive-phase chemotherapy treatment in children aged 1-18 with the primary outcome of the toxicity sum score. Secondary outcomes were chemotherapy-related toxicity, overall and event-free survival after 5 years in study patients. Methods: Intervention and control were given standard chemotherapy according to malignancy & tumor type. The intervention arm was provided with anthroposophic supportive treatment (AST); given as anthroposophic base medication (AMP), as a base medication for all patients and additional on-demand treatment tailored to the intervention malignancy groups. The control was given no AMP. The toxicity sum score (TSS) was assessed using NCI-CTC scales. Results: Data of 288 patients could be analyzed. Analysis did not reveal any statistically significant differences between the AST and the control group for the primary endpoint or the toxicity measures (secondary endpoints). Furthermore, groups did not differ significantly in the five-year overall and event-free survival follow up. Discussion: In this trial findings showed that AST was able to be safely administered in a clinical setting, although no beneficial effects of AST between group toxicity scores, overall or event-free survival were shown
