„Wutblech, gestrichen mit Krankheitsgedankenlack“
(2017-08)
Kindliche Ich-Erzähler sind in der aktuellen Kinder- und Jugendliteratur keine Seltenheit, einen narratologischen Paradigmenwechsel markiert Regina Hofmann im Rahmen der emanzipatorischen bzw. problemorientierten Kinderliteratur: „Die Zahl der bis in die 1970er Jahre noch vorherrschenden allwissenden Erzählinstanzen nimmt ab, während die Zahl der primär durch die Augen einer Reflektorfigur oder eines (kindlichen) Ich-Erzählers vermittelten Kinderromane stark ansteigt.“ Diese Tendenz hält – über den psychologischen ...

Lurchi
(KinderundJugendmedien.de – Wissenschaftliches Internetportal für Kindermedien und Jugendmedien, 2017-08-15)
Der vorliegende Beitrag beleuchtet Lurchis Abenteuer im Medienverbund aus Produktions- wie Rezeptionsperspektive und legt dabei ein besonderes Augenmerk auf die Sammelbände, die die Einzelhefte unter dem Titel Lurchis Abenteuer zusammenfassen. Methodisch ist dieser Artikel einer comictheoretischen (Narratologie, Multimodalität etc.) sowie literatur- (Lyrikanalyse, Handlungsschemata, Transtextualität) und kulturwissenschaftlichen Ausrichtung (Human-Animal und Gender Studies) bei gleichzeitiger Berücksichtigung der ...

The Adhesion of LSR Thermoplastic Composites after Storage Tests
(Society of Plastics Engineers, 2017)
The adhesion properties of liquid silicone rubber (LSR) and different thermoplastics (PC, PA, and PP) were examined in this investigation. In order to guarantee the adhesion of both components, an activation (silicatization) of the TP surface, which is a conventional method, was carried out. Furthermore, the long-term stability of the silicatization (storage of the activated surfaces) as well as the wetting behavior were investigated. Moreover, microscopic investigations were performed to analyze the activated ...

Beating the limits with initial correlations
(2017-11-28)
Fast and reliable reset of a qubit is a key prerequisite for any quantum technology. For real world open quantum systems undergoing non-Markovian dynamics, reset implies not only purification, but in particular erasure of initial correlations between qubit and environment. Here, we derive optimal reset protocols using a combination of geometric and numerical control theory. For factorizing initial states, we find a lower limit for the entropy reduction of the qubit as well as a speed limit. The time-optimal solution ...

Crack path predictions in fiber reinforced composites
(2017-09-06)
Composite materials exhibit beneficial features compared to conventional engineering material, e.g. a comparable strength and a reduced weight at the same time. To fully exploit these beneficial properties within technical structures, fracture mechanical concepts must be taken into account. The global fracture behavior in composite materials is related to the local delamination at interfaces between matrix and inclusion as well as the local fracture behaviors of the constituents. Because of their structure, the global ...

Cortesía verbal y competencia lingüística: la petición cortés como tradición discursiva
(2017-06-30)
Muchas técnicas de atenuación lingüística están estrechamente ligadas a estrategias de cortesía verbal. Un clásico en este contexto son las preguntas del tipo ¿Puedes pasarme el pan, por favor? que funcionan como petición cortés. La cuestión central es cómo esta conocida técnica de la petición cortés puede ser situada en el sistema de la competencia lingüística según Eugenio Coseriu. Resulta preciso aclarar si se trata de tradiciones idiomáticas que pertenecen al saber lingüístico o si se trata de una tradición ...

Heavy Metals and Polycyclic Aromatic Hydrocarbons in Urban Leaf Litter Designated for Combustion
(2017-03-03)
Vast amounts of leaf litter have to be disposed of by city administrations. This biomass has the potential for energy conversion, but contamination with pollutants can adversely affect this usage. We investigated leaf litter samples from the city of Kassel by analyzing their heavy metal and polycyclic aromatic hydrocarbon (PAH) concentrations. Leaf samples were indeed contaminated with heavy metals and PAHs and contamination was influenced by provenience and collection technique. A simple cleaning system of washing ...

Die Welt in Karten. Umbrüche und Kontinuitäten im Mittelalter
(2017-06-28)
This paper addresses the changes and continuities within the wide range of cartographic practices that existed in the Middle Ages. Following introductory thoughts on methodological issues, the text focuses on three different types of maps, all of which represent the world in its entirety: schematic maps, world maps and nautical charts. Within different texts, as independent artifacts or as atlases, these maps were employed for diverse purposes, such as the representation of fundamental principles, of encyclopaedic ...

Fusion of Ultrasonic and Spectral Sensor Data for Improving the Estimation of Biomass in Grasslands with Heterogeneous Sward Structure
(2017-01-21)
An accurate estimation of biomass is needed to understand the spatio-temporal changes of forage resources in pasture ecosystems and to support grazing management decisions. A timely evaluation of biomass is challenging, as it requires efficient means such as technical sensing methods to assess numerous data and create continuous maps. In order to calibrate ultrasonic and spectral sensors, a field experiment with heterogeneous pastures continuously stocked by cows at three grazing intensities was conducted. Sensor ...

Social Loafing in the Refugee Crisis: Information about Existing Initiatives Decreases Willingness to Help
(2017-05-11)
In light of the European refugee situation, we investigate how information about others’ support influences individuals’ willingness to help. When individuals see information about other people supporting refugees, they may either be influenced by a descriptive norm, and act accordingly. Alternatively, they may perceive that others are already doing the job, and thus engage in social loafing. In an experiment (N = 132), we tested these competing predictions. Specifically, participants were exposed to a map of Germany ...
