Adoption and utilisation of Zai pits for improved farm productivity in drier upper Eastern Kenya
(2020-03-06)
Inadequate and poorly distributed rainfall and declining soil fertility have led to low crop productivity in most smallholder farms in sub-Saharan Africa. As a result, there has been a renewed quest for sustainable and resource-use efficient agricultural production practices. Zai pit technology is a practice that has the potential to alleviate water stress and enhance soil fertility. We assessed the factors that influence farmers' adoption and utilisation of Zai pits in Tharaka-Nithi County in upper Eastern Kenya. ...

How do management practices and farm structure impact productive performances of dairy cattle in the province of Pichincha, Ecuador
(2020-11-11)
The combination of "ancestral knowledge" and modern agricultural techniques are increasingly used by Andes farmers, demonstrating its great importance as an ideal alternative to achieve international standards of productivity and sustainability. Pasture management has demonstrated its relevance in terms of milk volume and quality in farms located in the Ecuadorian highlands, showing a wide range of types of forage resource use, in its constant search for better animal yields from the occupancy rate. However, while ...

The Impact of Missing Values on PLS, ML and FIML Model Fit
(2020)
Structural equation modelling has become widespread in the marketing research domain due to the possibility of creating and investigating latent constructs. Today, several estimation methods are available, each with strengths and drawbacks. This study investigates how the established estimation methods of partial-least-squares (PLS), maximum likelihood (ML) and full-information maximum likelihood (FIML) perform with an increasing percentage of missing values (MVs). The research was conducted by investigating an adapted ...

Empirical Analyses of the Emergence and the Effect of Inter-municipal Cooperation
(2020-08)
This dissertation presents four empirical studies on inter-municipal cooperation (IMC). IMC gained prominence lately as alternative to local government reform. As local decision makers grow weary of the political costs of amalgamations and discouraging empirical evidence on the effectiveness of such reforms, IMC promises a more flexible approach to the provision of public goods and services.
What are the factors that drive the emergence of IMC? This question is answered by way of survival analysis, using data of ...

An approach to the use of technology in the cocoa-growing sector: a look from the producer
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2020-03-06)
A study was conducted to keep scientific record of the challenges and opportunities of the insertion of a mobile app for cocoa producers in the Colombia region as a prospective tool or strategy for technological transfer and appropriation into that sector. A survey with structured and semi-structured questions that pertained to cocoa producer men and women was conducted. The questions were related to the general conditions of their labour activities and were discriminant in the following categories: cocoa-grower ...

Literale Praktiken von ambulant betreuten Beschäftigten in Werkstätten für behinderte Menschen
(wbv, 2020)
Die LEO-Studien 2010 und 2018 sind für die in Deutschland lebende Wohnbevölkerung repräsentativ. Einige Bevölkerungsgruppen sind jedoch nur in kleinen Fallzahlen in der Studie abgebildet. Das kann den Eindruck erwecken, sie wurden für unwichtig gehalten werden. In der Praxis der Erwachsenenbildung sind jedoch Überlappungen, zum Beispiel zum Bereich Behinderung, an der Tagesordnung (Hirschberg und Lindmeier 2013). Das gilt auch spezifischer für die Alphabetisierung und Grundbildung (Ditschek 2013; Rosenbladt und Bilger ...

Development of CFD-Based Tip Clearance Loss and Deviation Models for Axial-Flow Turbines
(2020-01)
Accurate loss correlations are crucial for reliable turbine performance predictions with low-fidelity tools. However, conventional tip clearance models disregard some important loss effects, e. g. from the relative motion between blades and endwall, and their natural spanwise distributions, which are valuable for through-flow methods. The objective of this thesis is the development of more realistic tip clearance models by means of high-fidelity CFD simulations, which capture all three-dimensional flow effects and ...

Integrative Sportspielvermittlung im Grundschulalter
(2020-07)
Die (Sport-)Spiele Basketball, Fußball und Handball gehören nicht nur anhaltend zu den beliebtesten Freizeitaktivitäten von Kindern, sondern finden sich auch an allen Schulen im Unterrichtsalltag über die Curricula wieder. Die Ballspiele, mit ihrem komplexen Anforderungsprofil aus motorischen, kognitiven und sozial-kooperativen Fähigkeiten und Fertigkeiten, sind ideal geeignet um entsprechend des Doppelauftrags des erziehenden Sportunterrichts Kinder pädagogisch wertvoll zu fördern. Zur Einführung in die Spiele hat ...

Die Problematik der Minderung bei sozialen Dienstleistungen
(Nomos, 2020)
„Keine Minderung beim Dienstvertrag“. So lautet ein hergebrachtes zivilrechtliches Dogma. Nach diesem Dogma sollen sich Qualitätsmängel bei Dienstleistungen nicht auf die Vergütung auswirken, die als Gegenleistung für schlecht erbrachte Dienste beansprucht werden kann. Freilich: bei gewissen Dienstleistungen, die immer wieder Gegenstand öffentlicher Aufmerksamkeit werden, besteht offenbar das Bedürfnis, diese Art der Folgenlosigkeit schlechter Leistungsqualität zu vermeiden. Gemeint sind soziale Dienstleistungen, ...
