Herausforderungen für Planungsprozesse in Reservas Extrativistas in Rondônia, Brasilien
(2017-07)
Die Reservas Extativistas (ResEx, Sammelergebiete) in Brasilien sind weltweit einmalige Schutzgebiete. Sie werden seit den 1990er Jahren gegründet, um den Kautschukzapfern Schutz vor der Holzindustrie zu bieten und die nachhaltige Nutzung zu gewähren. Die Intention war die Selbstverwaltung durch die Bewohner. Allerdings wurde die Möglichkeit der Selbstverwaltung mit der Verabschiedung des Umweltschutzgesetzes im Jahr 2000 vollständig aufgehoben. Dies führt heute zu Interessenskonflikten zwischen Umweltschutzbehörde ...

Las tradiciones discursivas, la pragmalingüística y la lingüística del discurso
(2017)
El concepto de tradición discursiva desarrollado por la lingüística románica es central para una lingüística de enfoque cultural. Este concepto se basa en el modelo coseriano de la competencia lingüística, del cual se deduce la definición de las tradiciones discursivas. Una cuestión central de la lingüística con enfoque cultural es saber según qué principios, reglas y tradiciones se rigen los hablantes al realizar tareas comunicativas. El modelo de Coseriu abarca la sistematicidad lingüística de estas reglas y ...

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 ...

Phenotypic diversity, major genes and production potential of local chickens and guinea fowl in Tamale, northern Ghana
(2017-06-26)
Objective:
Our study provides information on phenotypes of local chickens and guinea fowl and their body measures as well as on major genes in local chickens in northern Ghana.
Methods:
Qualitative and morphometric traits were recorded on 788 local chickens and 394 guinea fowl in urban households in Tamale, Ghana.
Results:
The results showed considerable variation of color traits and numerous major genes in local chickens, while color variations and related genotypes in guinea fowl were limited. In local chickens, ...

The Positive Facet of Self-compassion Predicts Self-reported Use of and Attitudes toward Desirable Difficulties in Learning
(2017-08-09)
Previous research found that introducing difficulties and challenges during learning has desirable outcomes. With the present work, we investigated the question how the use of and the attitudes toward such learning strategies (so-called desirable difficulties) are related to self-compassion, a concept that describes the tendency to be understanding and kind to oneself when confronted with negative experiences. Evidence suggests self-compassion to be linked to less fear of failing, and further to higher control beliefs ...

The Dark Triad and the PID-5 Maladaptive Personality Traits: Accuracy, Confidence and Response Bias in Judgments of Veracity
(2017-09-21)
The Dark Triad traits—narcissism, Machiavellianism and psychopathy—have been found to be associated with intra- or interpersonal deception production frequency. This cross-sectional study (N = 207) investigated if the Dark Triad traits are also associated with deception detection accuracy, as implicated by the recent conception of a deception-general ability. To investigate associations between maladaptive personality space and deception, the PID-5 maladaptive personality traits were included to investigate if besides ...

Fat-containing cells are eliminated during Dictyostelium development
(2017-09-15)
Triacylglycerol is a universal storage molecule for metabolic energy in living organisms. However, Dictyostelium amoebae, that have accumulated storage fat from added fatty acids do not progress through the starvation period preceding the development of the durable spore. Mutants deficient in genes of fat metabolism, such as fcsA, encoding a fatty acid activating enzyme, or dgat1 and dgat2, specifying proteins that synthesize triacylglycerol, strongly increase their chances to contribute to the spore fraction of the ...

Die zeitgenössische Rezeption des genre sérieux im Frankreich des 18. Jahrhunderts
(2017-04)
Die vorliegende rezeptionsästhetische Untersuchung analysiert die zeitgenössische Wirkung des genre sérieux, das in der zweiten Hälfte des 18. Jahrhunderts zwischen Tragödie und Komödie tritt, sich an das Bürgertum wendet und auf die Gefühle abzielt. Mit spektakulären Inszenierungen an der Comédie Française und den Provinzbühnen wird es schnell zum Publikumsmagneten.
Inzwischen sind ein Großteil der Stücke des genre sérieux in Vergessenheit geraten. Die Literaturgeschichte beschränkt sich auf die ...

A scenario approach to modeling land-use changes and assessing associated environmental impacts in Southern Amazonia
(2017-03)
Humanity has left its footprint on the surface of the earth since it managed to purposefully employ tools and fire to its specific needs. Especially the conversion of natural habitats into agricultural productive land has transformed close to forty percent of the natural land-cover in order to satisfy global demands for food, raw materials, and energy. One current example of dynamic land-use and land-cover changes can be witnessed in Southern Amazonia. Spatially explicit land-use change models are applied to investigate ...
