Are farmer perceptions among significant determinants of adoption of agricultural diversity in Malawi? A case of Lilongwe district
(2020-12-14)
Agricultural diversity can strengthen resilience of livelihood of farmers to climate change and market uncertainties while, potentially at the same time, o ering better dietary and nutritional prospects for households. Adoption of agricultural diversity in Malawi is low. Policy-makers, researchers, non-governmental organisations (NGOs), and extension staff need to understand dynamics of adoption of agricultural diversity in order to develop appropriate policies and interventions to promote agricultural diversification. ...

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 ...

Weiterbildung: Institutionelle Grundlagen und Handlungsfelder
(2022-03)
Aus zwei Gründen gewinnt die Weiterbildung an Bedeutung: Einerseits entsteht im Zuge der digitalen und ökologischen Transformation der Arbeitswelt ein großer Qualifizierungsbedarf, weil sie zu einem Wandel von Berufsfeldern und -tätigkeiten führt. Andererseits spielt Weiterbildung auch mit Blick auf benachteiligte Gruppen am Arbeitsmarkt eine zentrale Rolle für deren Verbleib bzw. erfolgreiche Integration in Erwerbsarbeit. Allerdings ist die Ausgestaltung der Weiterbildung durch institutionelle Komplexität geprägt. ...

Raumwinkeloptimierte Elektron-Photon Koinzidenzmessungen nach der Anregung mit Synchrotronstrahlung unter Verwendung zeitlich verschieden strukturierter Füllmuster des Speicherrings
(2021-05)
Für die Untersuchung von Relaxationspfaden von angeregten mikroskopischen Systemen nehmen Messmethoden eine zentrale Rolle ein, bei denen emittierte Teilchen so gemessen werden, dass eine physikalische Korrelation zwischen Ihnen nachgewiesen werden kann. Denn nur durch den Nachweis dieser Korrelationen ist es bei stark verzweigten und sich unter Umständen kreuzenden Relaxationspfaden, diese Pfade eindeutig nachzuverfolgen.
Diese sogenannten Koinzidenzmessungen werden seit ihren ersten Anwendungen in den 1920er Jahren ...

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 ...

Dynamic Tensile Deformation of High Strength Aluminum Alloys Processed Following Novel Thermomechanical Treatment Strategies
(2020-05-14)
Herein, the effects of a very recently introduced novel thermomechanical process route on the microstructural evolution and dynamic tensile deformation behavior of two different precipitation hardenable aluminum alloys, i.e., AA6082 and AA7075, are studied. The investigated materials are hot formed and quenched in differently tempered tools to reveal the influence of cooling rate. Microstructure analysis is conducted to study the influences of different cooling strategies on the microstructure evolution and prevailing ...

Spatial variation of nutritional content in Enhalus acoroides (L.f.) royle seeds and seed pods
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2020-04-14)
Coastal and small islands communities generally have limited access to fresh vegetables. The tropical seagrass Enhalus acoroides tends to fruit during the rainy season, when sea conditions often prevent fishing. Coastal communities in several countries, including Indonesia, traditionally collect seagrass fruits for food and traditional remedies. This study measured levels of 6 key nutrients in Enhalus acoroides fruit (seeds and seedpods). Samples were collected from two sites where E. acoroides fruits are harvested ...

The ‘fine balance’ of West African savannah parklands: biomass generation versus firewood consumption
(2022-03-15)
In sub-Saharan Africa, the long-awaited fuelwood gap, resulting of the unbalance between a declining supply of firewood and the increasing demand of households, remains a latent social-ecological challenge. As its quantitative basis remains elusive, we have assessed agroforestry parklands, assumedly main providers of firewood, and firewood consumption in Dassari, Benin and Dano, Burkina Faso, both in the West African savannah. Data collected included botanical inventories, tree biomass estimations, householders’ ...

Effects of Petiveria alliacea (guinea hen weed) leaf extract on fermentation parameters, nutrient digestibility and faecal worm egg count in growing West African dwarf goats
(2022-03-21)
Medicinal plants are used in animal feeding as natural antimicrobial to improve nutrient utilisation and health status of animals. This study assessed the effects of varying concentration of Petiveria alliacea leaf extract (PLE) on fermentation parameters, nutrient digestibility, nitrogen utilisation and faecal worm egg count of growing West African dwarf goats. Twenty- four (24) growing West African dwarf bucks with average body weight of 8.50 ± 0.55 kg were divided into four treatment groups with six bucks each ...
