Finding alternatives: Canadian attitudes towards novel foods in support of sustainable agriculture
(2021-09-29)
Global agriculture and farming practices account for roughly a quarter of total atmospheric emissions. Protein agricultural is especially prone to green-house gas emissions. There is a need to find alternatives, both in the form of protein and sustainable practices in providing alternative protein sources. However, sustainable agricultural practices must consider consumer behaviour and attitude towards switching protein sources. In this study, we carried out a survey of 993 Canadians in order to better understand the ...

Barrieren als gesellschaftliche Hindernisse - Sozialwissenschaftliche Überlegungen
(Verlag Julius Klinkhardt, 2021)
Barrierefreiheit und auch das übergeordnete Prinzip der Zugänglichkeit sind am Verhältnis von Individuum und Gesellschaft ausgerichtet, also konkret an den individuellen Lebensmöglichkeiten innerhalb der jeweiligen gesellschaftlichen Bedingungen unter Beachtung von Zeit und Ort. Hiermit ist die Frage nach Barrieren gestellt, die einzelne Menschen und auch Gruppen von Menschen in ihrer Teilhabe an der Gesellschaft in unterschiedlicher Weise behindern. Welche Barrieren bestehen wo für wen? Wie lassen sich diese konkret ...

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 ...

Why did OPEC lose its price setting power during the 1980s?
(2021-05)
Since the surge in oil prices during the 1970s there was an increased academic interest in explaining the formation of oil prices and the critical role played by OPEC in this process. A variety of economic models were established to explain the rise of price setting power by OPEC reflected in the massive price increases. During the 1980s, however, against many projections, the surge in oil prices came to a hold and from the 1980s on started to decrease, finally collapsing in 1986 to an unprecedented low. These ...

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 ...

Socioeconomic inequality in academia
(2021)
Sozioökonomische Ungleichheit ist eine Herausforderung für das deutsche Wissenschaftssystem. Sie verhindert, dass Nachwuchswissenschaftler aus benachteiligten sozialen Gruppen ihr Talent voll ausschöpfen und so zum allgemeinem wissenschaftlichen als auch ökonomischen Fortschritt beitragen können. Die vorliegende Dissertation greift diese Problematik auf und versucht sowohl verlaufende methodische Probleme in der Generierung von Datenbank zu adressieren als auch eine Datenbank zu erstellen und wissenschaftsökonomische ...

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 ...

Satzbaupläne als Zeichen: die semantischen Rollen des Deutschen in Theorie und Praxis
(De Gruyter, 2021)
Thema des Beitrags sind Satzbaupläne als komplexe syntaktisch-semantische Sprachzeichen. An der Schnittstelle von Valenztheorie (GTA 2017; Ágel 2015, 2000) und Konstruktionsgrammatik (Goldberg 1995; Schneider 2014) werden Satzbaupläne nicht als formale Zeichen wie in traditionellen Satzbauplankonzepten, sondern als abstrakte Zeichen mit einer Formseite (Satzglieder) und einer Inhaltsseite (signifikativ-semantische Rollen) aufgefasst (GTA 2017; Höllein 2019). Die Satzbauplanzeichen sind dabei vollständig abstrakte ...

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 ...
