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 ...

Machines as teammates: A research agenda on AI in team collaboration
(2019-07-06)
What if artificial intelligence (AI) machines became teammates rather than tools? This paper reports on an international initiative by 65 collaboration scientists to develop a research agenda for exploring the potential risks and benefits of machines as teammates (MaT). They generated 819 research questions. A subteam of 12 converged them to a research agenda comprising three design areas – Machine artifact, Collaboration, and Institution – and 17 dualities – significant effects with the potential for benefit or harm. ...

Why different trust relationships matter for information systems users
(2015-12-08)
Technology acceptance research has shown that trust is an important factor fostering use of information systems (IS). As a result, numerous IS researchers have studied factors that build trust in IS. However, IS research on trust has mainly focused on the trust relationship between the user and the IS itself, largely neglecting that other targets of trust might also drive IS use from a user’s point of view. Accordingly, we investigate the importance of different targets of trust in IS use. Therefore, we use the concept ...

Quality of black bean seeds harvested with different moisture contents and submitted to two different storage systems
(2019-12-05)
Bean (Phaseolus vulgaris L.) is one of the main foods of the Brazilian diet. However, to achieve high yields, one of the determining factors is seed quality, which can be influenced by harvesting time and storage. The objective of this work was to evaluate the physical quality and physiological performance of black bean seeds as function of the moisture content at harvest and storage method. For that, black bean seeds, cultivar BRS Campeiro, were used. The harvest was performed when the seeds reached moisture contents ...

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 ...

A unified and memory efficient framework for simulating mechanical behavior of carbon nanotubes
(2015-06-01)
Carbon nanotubes possess many interesting properties, which make them a promising material for a variety of applications. In this paper, we present a unified framework for the simulation of the mechanical behavior of carbon nanotubes. It allows the creation, simulation and visualization of these structures, extending previous work by the research group “MISMO” at TU Darmstadt. In particular, we develop and integrate a new matrix-free iterative solving procedure, employing the conjugate gradient method, that drastically ...

Dietary habits and nutritional status among school children in rural and urban areas: A comparative study from Bogor, Indonesia
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2018-12-26)
When Indonesia was combating child undernutrition, overnutrition emerged which made the situation more complex. In fact, dwelling area like rural versus urban is one of the direct determi- nants which play a big role in shaping dietary habits and nutritional status in population. However, there is a lack of data that shows dieteray habits between urban and rural areas in Indonesia. This study aims to compare the dietary habits and nutritional status between children living in urban and rural areas in Bogor. This study ...

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 ...

A sequence analysis of organic and conventional food consumers’ visual information acquisition
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2019-07-26)
It is of significant importance in food marketing to know which pieces of information available during shopping are most relevant to consumers. The visual search behaviour of consumers allows inference on the relevance of information based on what information is acquired and when. It is assumed that price is a major barrier to the purchase of organic food. However, little is known about consumers’ actual acquisition of information on organic food prices. To examine the information acquisition behaviour of consumers ...

A comparison of individual and group behavior in a competition with cheating opportunities
(2020)
While it is well established that individuals and groups make different economic decisions, the reasons for the behavioral differences are still not fully understood. We experimentally compare individual and group behavior in a competitive setting where cheating can be used to outperform the competitor. Our design allows us to exogenously control for the type of the decision maker, the type of the competitor, and whether the competitor is able to cheat or not. The results show that there is much more cheating in ...
