Was steht dem Wissenstransfer zur Tiergesundheit in der landwirtschaftlichen Nutztierhaltung entgegen?
(2021-09)
Produktionskrankheiten sind (auch in der ökologischen) Nutztierhaltung weit verbreitet und werden in der Gesellschaft zunehmend als negativer externer Effekt wahrgenommen. Sie führen zum Einsatz von Antibiotika, sind Ausdruck eines beeinträchtigten Tierwohls und verursachen den landwirtschaftlichen Betrieben Ausfallkosten. Obwohl zu den Ursachen und der Vorbeugung viel geforscht wurde sind Produktionskrankheiten weit verbreitet. Ziel der vorliegenden Arbeit war es, den mit dem Begriff Wissenstransfer beschriebenen ...

Fine-scale grassland monitoring using unmanned aerial vehicle borne remote sensing
(2020-04)
RS is widely employed as a non-destructive methodology to monitor grasslands. Usage of UAV as the RS platform benefits to provide high spatial (fine-grain) and temporal resolution, unclouded data over small grassland extent. Therefore, this thesis evaluated the applications of UAV-borne RS for fine-scale grassland monitoring along with practical farm condition. Grass biomass estimation, predicting forage quality of grass and mapping invasive lupine in grasslands are considered as applications of UAVborne RS.

Investigation of drying behavior and color development of beef slices for development of non-invasive monitoring approaches
(2021)
Meat drying has a long tradition worldwide and technically dried meat is increasingly valued as a low-fat snack or high-protein food product. Convection drying is widely used in industrial food preservation and has to provide high process efficiency and high product qualities, which can be contradictory. Therefore, it is important to understand the changes that occur in the product in order to develop drying strategies that consider process and product efficiency each at an acceptable level. The objective of this ...

Towards Empowering Educators to Create their own Smart Personal Assistants
(ScholarSpace, 2020)
Despite a growing body of research about the design and use of Smart Personal Assistants such as Amazon’s Alexa or Google’s Assistant, little is known about their ability to help educators offering individual support in large-scale learning environments. Smart Personal Assistant ecosystems empower educators to develop their own agents without deep technological knowledge. The objective of this paper is to design and validate a method that helps educators to create Smart Personal Assistants as learning tutors. Using ...

Income Diversification trough Animal Husbandry for Smallholder Vanilla Farmers in Madagascar
(2020-05-07)
The SAVA region in northeastern Madagascar is the largest vanilla producing area globally. Here, we investigated the role of animal husbandry (AH) for income diversification of small-scale vanilla farmers. To do this, 300 household heads were interviewed about livestock ownership, management and marketing. This information was complemented by data from 1800 households (HHs) on involvement in vanilla production (VP) and AH. Throughout the region, 83 % of HHs produced vanilla and 84 % kept livestock. Chicken-keeping ...

Does the non-farm sector affect production efficiency of the Vietnamese agricultural sector? A stochastic frontier production approach
(2020-12-24)
This study examines the impact of the non-farm sector on farm value-added and production efficiency in the Vietnamese agricultural sector by using data from the Vietnam Household Living Standard Survey 2012. Production function and stochastic frontier production analysis is used to determine the impact, and the instrumental variables method is applied to address endogeneity. We find that the Vietnamese non-farm sector has a positive effect on both farm value-added and efficiency. This result indicates that income ...

Towards a Technique for Modeling New Forms of Collaborative Work Practices – The Facilitation Process Model 2.0
(University of Hawaii at Manoa, Hamilton Library, ScholarSpace, 2020)
Collaboration Engineering (CE) is an approach for the design and deployment of repeatable collaborative work practices that can be executed by practitioners themselves without the ongoing support of external collaboration professionals. A key design activity in CE concerns modeling current and future collaborative work practices. CE researchers and practitioners have used the Facilitation Process Model (FPM) technique. However, this modeling technique suffers from a number of shortcomings to model contemporary ...

Competitiveness of sea buckthorn farming in Mongolia: A policy analysis matrix
(2020-05-09)
Sea buckthorn (Hippophae rhamnoides L.) provides multiple products that are beneficial to human health. In addition, the plant is also used to combat desertification. In contrast to the vast ecological, agronomic and nutritional literature on this species, little is known about its economic and marketing aspects, particularly in Central Asia. We therefore analysed the private and social competitiveness of sea buckthorn farming in 21 households of Bulgan county of Khovd province in Mongolia. The results show that half ...

The Acceptance of Serious Games by Mental Health Service Users and Mental Health Professionals: An International Comparison Study
(2021)
Research aim. This study investigates which determinants predict the intention to use SG in psychotherapeutic settings among both relevant application groups: mental health service users (individuals with psychotherapy experience either currently or in the past) and mental health professionals. Since ethnicity, socioeconomic status, and culture highly interplay with (e-mental health) technology uptake (Clough et al., 2019), SG acceptability was assessed in several countries (N = 13) by particularly considering the ...

The Passive Revolution of Good Living
(2020)
The PhD thesis "The Passive Revolution of Good Living: Class Struggle and Productive Transformation Policy in Ecuador (2007-2017)" suggests an interpretation of Ecuador's so-called ‘Citizens’ Revolution’ – CR – as the political project of a 'cadre fraction’: a ‘state class fraction’ whose legitimacy and political power is grounded in specialized knowledge and planning capabilities. Breaking the “catastrophic equilibrium” in which the anti-neoliberal forces and the dominant classes ended up at the beginning of the ...
