Reaction to a low-carbon footprint food logo and other sustainable diet promotions in a UK University’s Student Union ‘Living Lab’
(2021-02-21)
Purpose: Public sector catering outlets have been proposed as ideal places to try new sustainable food choice interventions. We report on promotions conducted as part of a “Living Lab” at the University of Sheffield Students Union during 2019.Methodology: Activities include 1) a survey of dietary habits, attitudes and knowledge of staff and students (n=643). 2) A low environmental impact indicator logo was created and implemented in different ways across four food outlets in the Students Union (some outlets also ...

Awareness creation of smallholder farmers on and adoption of push-pull technology reduces fall armyworm (Spodoptera frugiperda) infestation on maize in Hawzien Woreda, Northern Ethiopia
(2020-11-28)
Recently, maize (Zea mays L.) production by smallholder farmers in Ethiopia has been threatened by an exotic pest called fall armyworm (FAW) (Spodoptera frugiperda J.E. Smith; Lepidoptera, Noctuidae). Devising or adopting sustainable, effective, affordable and smallholder farmers-friendly management strategies for the control of this pest are, therefore, vital. Push-Pull Technology (PPT) is considered one of the management methods for the control of FAW in East Africa. Therefore, the aim of this study is to determine ...

Einleitung
(De Gruyter, 2020)
Dialoge sind die grundlegende Erscheinungsform von Kommunikation. Die Teilhabe an Wissen und kultureller Praxis ist in hohem Maße sprachlich gebunden und wird dialogisch vermittelt. Für diese Vermittlung ist das Gelingen von Gesprächen die Voraussetzung und dementsprechend ist die linguistische, literaturwissenschaftliche, kulturwissenschaftliche, soziologische oder philosophische Sprachbetrachtung reich an Modellen und Beschreibungen, die die Prinzipien und Bedingungen gelingender Gespräche zu begreifen versuchen.

Diversification of maize-based intercropping systems in tropical rainforest agroecosystem of Nigeria: productivity, profitability and soil fertility
(2021-02-07)
Monocropping of maize is becoming unsustainable in the rainforest agroecosystem of Nigeria. This is due to the adverse impact of climate change such as increasing pests and disease infestations and erratic rainfall patterns coupled with underutilization of resources. Smallholder farmers in this tropical agroecosystems are in dire need of adaptive and resilient cropping systems to ensure food, nutrition, and livelihood security. Thus, this study aims to identify adaptive maize-based systems for the rainforest agroecology ...

Explicit Description Of Isogeny And Isomorphism Classes Of Drinfeld Modules Of Higher Rank Over Finite Fields
(2020)
When jumping from the number fields theory to the function fields theory, one cannot miss the deep analogy between rank 1 Drinfeld modules and the group of root of unity and the analogy between rank 2 Drinfeld modules and elliptic curves. But so far, there is no known structure in number fields theory that is analogous to the Drinfeld modules of higher rank r ≥ 3. In this thesis we investigate the classes of those Drinfeld modules of higher rank r ≥ 3 defined over a finite field L. We describe explicitly the Weil ...

The potential of UAV-based remote sensing for the prediction of aboveground biomass and N fixation in legume-grass mixtures
(2020-07)
The world population is growing steadily and with it the demand for meat and animal protein. A major source of feed for livestock is grassland, which serves as high quality and protein rich forage. In addition to permanent grassland, temporary grassland is a valuable crop rotation element, especially in organic farming, since legumes in legume-grass mixtures can fix atmospheric nitrogen (NFix). To further increase the intensification in agriculture, reliable non-destructive measurement techniques are needed as an ...

Zur Entstehung der Halbtagsschule in Deutschland. Eine bildungspolitische und pädagogische Fehlentwicklung?
(2021)
Ziel der Arbeit ist den historischen Weg darzustellen, um damit einen offeneren und besseren Blick auf die Gegenwart zu bekommen, dass die Entstehung der Vormittagsschule zuerst an höheren und später auch an Volksschulen m. E. möglicherweise eine bildungspolitische und pädagogische Fehlentwicklung darstellte, die es heute aus pädagogischen, sozialpädagogischen aber auch wirtschaftlichen Gründen zu korrigieren gilt.

Towards A Better Understanding of Workplace Coaching: On Goal Activities, Exploration Practices, and Coaches’ Life Satisfaction
(2020)
Whereas there is a high and ever-increasing demand for coaching worldwide (International Coach Federation, 2016) and meta-analytical findings suggest that coaching is generally effective (e.g., Jones et al., 2016; Sonesh, Coultas, Lacerenza et al., 2015), little is still known about standards for “good” coaching practice (e.g., Bono et al., 2009; Vandaveer et al., 2016). Across three studies, this dissertation investigates relevant facets of coaching practice. It addresses the questions of how coaches practice workplace ...

Endozoochorer Transport von Pflanzendiasporen durch den Rothirsch (Cervus elaphus)
(2020)
Ziel der Arbeit ist es, den endozoochoren Ausbreitungserfolg über den Rothirsch für Pflanzenarten wertgebender Offenlandlebensräume zu untersuchen. Dazu wurden folgende Fragestellungen bearbeitet: (i) Welche Artenzusammensetzung weist das endozoochor transportierte Diasporenspektrum auf? (ii) Profitieren vor allem Offenlandarten von dieser Ausbreitungsweise und warum? (iii) Lassen Vergleiche zwischen angebotenem und transportiertem Artenspektrum auf flächenvernetzende Streifbewegungen im Rothirschlebensraum schließen? ...

Evaluation of antioxidant activity of the phenolic composition of Syrian Arbutus andrachne L.
(2020-10-18)
Arbutus andrachne L. (Grecian Strawberry tree) is widespread in the Mediterranean and the Black Sea Regions. This study aimed at determining total phenolic content and antioxidant activity of Arbutus andrachne parts (flowers, leaves, bark and fruit) collected from different parts of the Latakia Province (Syria). Our work is the first to conduct this experiment on the selected plants in Syria.
The fresh samples were extracted using ethanol 50% as an extraction solution, then the total contents of the phenolic compounds ...
