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 ...

High-Quality Solid Fuel Production from Leaf Litter of Urban Street Trees
(2016-11-30)
Leaf litter is a growing concern for cities. Due to adherent dirt such biomass is rarely utilized nowadays but may constitute a renewable energy source for communities or private households. Leaf litter from main roads, residential areas and city centres collected by the vacuum technique or the sweeper technique was sampled and analysed for ash content and chemical composition. Ash content of leaf litter collected by the sweeping technique was higher (21.6%–40.1% dry matter, DM) than in material collected by the ...

A note on pigs’ knowledge of hidden objects
(2013-08-12)
Object permanence is the notion that objects continue to exist even when they are out of observer´s sight. This ability is adaptive not only for free ranging animals who have to cope with a dangerous and highly changeable environment, allowing them to be aware of predators sneaking in their proximity or to keep track of conspecifics or food sources, even when out of sight. Farm animals, too, might profit from object permanence as the ability to follow the trajectory of hidden food or objects may lead to a higher ...

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 ...

Distributing mathematical practice of third and seventh graders: Applicability of the spacing effect in the classroom
(2018-10-23)
We examined the effect of distributed practice on the mathematical performance of third and seventh graders (N = 213) in school. Students first received an introduction to a mathematical topic, derived from their curriculum. Thereafter, they practiced in one of two conditions. In the massed condition, they worked on three practice sets in 1 day. In the distributed condition, they worked on one practice set per day for 3 consecutive days. Bayesian analyses of the performance in two follow‐up tests 1 and 6 weeks after ...

Cultural Adaption of Hypermedia
(2012)
Culturally adapted hypermedia design attracts increasing scientific attention. Complementing the conventional human-computer interaction studies we investigate the current state of companies’ cultural adaptation of their websites. This study evaluates a sample of 215 websites with respect to design and navigational aspects. Subsequently, we discuss the possibilities of structuring hypermedia and enabling the adaptation to culturally bounded user expectations. Moreover, we introduce metrics for assessing navigational ...

General Belief in a Just World Is Positively Associated with Dishonest Behavior
(2017-10-10)
According to the just-world theory, people need to – or rather want to – believe that they live in a just world where they will receive what they earn and consequently earn what they receive. In the present work, we examined the influence of people’s general and personal beliefs in a just world (BJW) on their (dis)honest behavior. Given that general BJW was found to be linked to antisocial tendencies, we expected stronger general BJW to be linked to more dishonesty. Given that personal BJW was found to be correlated ...
