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. ...

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 ...

On the Influence of Microstructure on the Corrosion Behavior of Fe–Mn–Al–Ni Shape Memory Alloy in 5.0 wt% NaCl Solution
(2020-10-03)
Herein the corrosion behavior of Fe–Mn–Al–Ni shape memory alloys characterized by different microstructures in a 5.0 wt% NaCl solution is investigated. Open circuit potential and potentiodynamic polarisation tests are conducted. Generally, Fe–Mn–Al–Ni shows corrosion properties being similar to pure iron. However, the polarization curves of single crystals indicate the presence of an unstable passive system. The corrosion damage is analyzed by means of optical microscopy and electron microscopy. It is revealed that ...

Determinants of households’ membership in agricultural cooperatives in Bhutan
(2021-10-05)
The Royal Government of Bhutan has been promoting agricultural cooperatives (ACs) in the country; however, the number of people joining ACs is small. This study was conducted to identify the factors influencing households' decision to join ACs in Central Bhutan. A cross-sectional survey was conducted to collect data from 384 households (192 AC members and 192 non-AC members). Trained enumerators collected data in June and July 2018 using structured questionnaires. The binary logistic regression showed that households ...

Accelerating Entrepreneurial Decision-Making Through Hybrid Intelligence
(2020)
Purpose: Previous studies revealed that around 75 percent of all start-ups fail at an early stage. One main reason for this tremendous failure rate is that entrepreneurs are typically confronted with high levels of uncertainty about the viability of their proposed business idea. Following this argumentation, entrepreneurial decision-making can be defined as complex decision-making problem under both risk and uncertainty. While risk includes quantifiable probabilities, uncertainty describes situations where neither ...

Symmetrien von Differentialgleichungen via Vessiot-Theorie
(2021-04)
Die übliche Definition des Symmetriebegriffs einer Differentialgleichung lautet wie folgt: Symmetrien sind Transformationen, die Lösungen wieder in Lösungen überführen. Modelliert man Differentialgleichungen als Untermannigfaltigkeiten eines Jetbündels, so lassen sich zwei Arten von Symmetrien unterscheiden: innere und äußere. Der erste Fall entspricht einer Transformation, die ausschließlich auf der Differentialgleichung definiert ist. Im zweiten Fall ist die betrachtete Transformation auf dem gesamten umgebenden ...

Between cripping and reclaiming
(2022)
Disability Studies promote different feeling strategies pushing for social change towards a more inclusive and less ableist society. There is a utopian touch to this: How can we change the world by feeling differently about disability? Disabled people have discussed how to navigate ableism’s emotional toll probably since the Disability Rights movement’s roots. The paper-at-hand oscillates between two strategies that Disability Studies scholars and activists have advocated for: Cripping – deliberately changing one’s ...

Investigation of residual stresses in polypropylene using hot plate welding
(2020-08-05)
During the cooling process of the molten material, residual stresses appear because the reduced volume of the cooled material cannot fully fill the space formerly occupied by the molten material. The morphology in and around the weld is formed by different factors depending on the material and process parameters. Different morphological structures relate to different mechanical properties. The process parameters and the welding results including morphology and residual stress are linked together. In this article, ...
