Decision Making in Projects in Cultural Context
(2020)
This study presents the investigation about the decision making styles of German and Pakistani managers in national cultural context who have been working on projects. It becomes very important to understand the national culture when doing the international projects. Different studies have shown that national culture has significant impact upon managerial practices especially decision making. Germany is a developed country and various German companies perform projects in developing countries like Pakistan. In projects, ...

Influence of stage of ripening and dietary concentration of Noni (Morinda citrifolia L.) powder on broiler performance
(2020-04-08)
Phyto-additives in poultry diets enhance growth, feed eciency and product quality and minimise the possible risk of residues from chemical additives. There are reports on the use of noni (Morinda citrifolia) fruit powder as phytoadditive in poultry diets but information on the eect of fruit ripening is scanty. Hence, this study compared the eect of unripe and ripe noni fruit owder on broiler performance. A control diet without and 4 diets containing two levels (0.25 and 0.5 %) unripe and ripe fruit powder were fed ...

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 ...

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 ...

Effect of Compositional Variation Induced by EBM Processing on Deformation Behavior and Phase Stability of Austenitic Cr-Mn-Ni TRIP Steel
(2020-01-24)
Electron beam melting (EBM) is an established powder bed-based additive manufacturing process for the fabrication of complex-shaped metallic components. For metastable austenitic Cr-Mn-Ni TRIP steel, the formation of a homogeneous fine-grained microstructure and outstanding damage tolerance have been reported. However, depending on the process parameters, a certain fraction of Mn evaporates. This can have a significant impact on deformation mechanisms as well as kinetics, as was previously shown for as-cast material. ...

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 ...

The diversity and contribution of indigenous edible fruit plants to the rural community in the Gayo Highlands, Indonesia
(2020-05-15)
The Gayo Highlands offer different indigenous edible fruit species (IEFs) used by the rural community, essentially to provide products such as fruits, oil, medicine, nuts, and fodder. In recent times, these IEFs are being threatened by over-exploitation and biodiversity loss. This study, therefore, aimed to explore the diversity of IEFs and evaluate its contribution to the enhancement of the rural community income in the Gayo Highlands region. The plant materials were randomly collected from nine villages in three ...

A Conversational Agent to Improve Response Quality in Course Evaluations
(Association for Computing Machinery, 2020)
Recent advances in Natural Language Processing (NLP) bear the opportunity to design new forms of human-computer interaction with conversational interfaces. We hypothesize that these interfaces can interactively engage students to increase response quality of course evaluations in education compared to the common standard of web surveys. Past research indicates that web surveys come with disadvantages, such as poor response quality caused by inattention, survey fatigue or satisficing behavior. To test if conversational ...

Typology of smallholder’s pig production systems in South Kivu, Democratic Republic of Congo: Challenges and opportunities
(2020-06-30)
Pig farming plays an important role in farmers’ livelihoods in many tropical countries. It contributes to food security of the poorest as well as the development of rural economy through multiplier effects. In the South Kivu province, pig farms are almost exclusively owned by smallholders. A few studies have attempted to describe thoroughly pig farming systems in this province. This study was undertaken to characterise pig production systems, in order to better understand their current situation, namely constraints ...

Occurrence, distribution and alternative hosts of Wheat streak mosaic virus infecting ginger in Kaduna State, Nigeria
(2020-06-29)
A field survey was conducted during the 2018 rainy season (June – October) in three major ginger producing Local Government Areas (LGAs) of Kaduna State, Nigeria to determine the occurrence and spread of wheat streak mosaic virus (WSMV) infecting ginger. Symptomatic and asymptomatic ginger leaf samples (n=180) and weed samples (n=45) were collected from the surveyed fields and indexed against WSMV using Double Antibody Sandwich Enzyme-linked Immunosorbent Assay (DAS-ELISA). The results obtained showed that WSMV ...
