The organic mindset: insights from a mixed methods grounded theory (MM-GT) study into organic food systems
(2021-04-23)
A broad understanding of food systems includes a complex web of activities, outcomes and drivers, encompassing not only the food and agriculture sectors, but also the social norms and cultures in which those activities are embedded. The organic food and farming movement has lately been portrayed as a food system of its own right, since it contains all necessary sub-systems, consisting of food environments, distribution networks, processing, as well as production and supply, all of which are bounded by an organic ...

Rigorous 3D modeling of confocal microscopy on 2D surface topographies
(2021-06-07)
Although optical 3D topography measurement instruments are widespread, measured profiles suffer from systematic deviations occurring due to the wave characteristics of light. These deviations can be analyzed by numerical simulations. We present a 3D modeling of the image formation of confocal microscopes. For this, the light-surface interaction is simulated using two different rigorous methods, the finite element method and the rigorous coupled-wave analysis. The image formation in the confocal microscope is simulated ...

Food System Outcomes: An Overview and the Contribution to Food Systems Transformation
(2020-09-24)
The interest in food system discourse has been increasing over time, however, the understanding of what makes a food system is still subject to variations depending on the research focus. While the earlier discourse was mainly value chain centered, the recent years have witnessed a shift in focus toward a more holistic view embracing the complex character of food systems. An indispensable component of the food systems approach are the food system outcomes that represent the results, or consequences, of the food system ...

On the Intergranular Corrosion Properties of Thin Ferritic Stainless Steel Sheets Welded by Fiber-Laser
(2020-08-12)
In the present investigation, thin sheets of stabilized and unstabilized ferritic stainless steel were welded in butt joint configuration using irradiation of a 1070 nm fiber-laser. Using optical microscopy, the microstructural evolution upon alternating heat input was characterized. In addition to that, hardness and tensile tests were carried out on the specimens. Detailed focus was given to the intergranular corrosion properties, which were investigated on basis of the Strauss test with different times of exposure ...

Topic space trajectories
(2021-05-15)
The annual number of publications at scientific venues, for example, conferences and journals, is growing quickly. Hence, even for researchers it becomes harder and harder to keep track of research topics and their progress. In this task, researchers can be supported by automated publication analysis. Yet, many such methods result in uninterpretable, purely numerical representations. As an attempt to support human analysts, we present topic space trajectories, a structure that allows for the comprehensible tracking ...

Multi-Scale Governance of Sustainable Natural Resource Use—Challenges and Opportunities for Monitoring and Institutional Development at the National and Global Level
(2016-08-09)
In a globalized economy, the use of natural resources is determined by the demand of modern production and consumption systems, and by infrastructure development. Sustainable natural resource use will require good governance and management based on sound scientific information, data and indicators. There is a rich literature on natural resource management, yet the national and global scale and macro-economic policy making has been underrepresented. We provide an overview of the scholarly literature on multi-scale ...

Reviewing interfirm relationship quality from a supply chain management perspective
(2020-09-23)
With the overlap of the interfirm relationship quality and supply chain management research in mind, this paper reviewed 100 recent, scientific, English-language papers on interfirm relationship quality based on a categorisation schema derived from a conceptual framework of supply chain management. We aim to contribute to the existing supply chain management literature by providing an insight into the connections of supply chain performance with buyer–supplier relationship quality from the relationship quality scholars’ ...

Soil N₂O flux and nitrification and denitrification gene responses to feed-induced differences in the composition of dairy cow faeces
(2021-05-17)
Faeces from cows with different milk yield and non-lactating cows were applied to soil to investigate whether soil N₂O efflux is related to feeding-induced differences in faecal microbiome and abundances of nitrification and denitrification genes. Fungal 18S-rRNA gene abundance was the highest in the faeces of the non-lactating group. The 18S-rRNA/ergosterol ratio showed a strong positive correlation with the 18S-rRNA/fungal glucosamine ratio. The milk-yield groups did not affect the gene abundances of bacterial 16S ...

Analysis of Pigment-Dispersing Factor Neuropeptides and Their Receptor in a Velvet Worm
(2020-05-12)
Pigment-dispersing factor neuropeptides (PDFs) occur in a wide range of protostomes including ecdysozoans (= molting animals) and lophotrochozoans (mollusks, annelids, flatworms, and allies). Studies in insects revealed that PDFs play a role as coupling factors of circadian pacemaker cells, thereby controlling rest-activity rhythms. While the last common ancestor of protostomes most likely possessed only one pdf gene, two pdf homologs, pdf-I and pdf-II, might have been present in the last common ancestors of Ecdysozoa ...

An Overview of the Use of Genotyping Techniques for Assessing Genetic Diversity in Local Farm Animal Breeds
(2021-07-06)
The number of local farm animal breeds is declining worldwide. However, these breeds have different degrees of genetic diversity. Measuring genetic diversity is important for the development of conservation strategies and, therefore, various genomic analysis techniques are available. The aim of the present work was to shed light on the use of these techniques in diversity studies of local breeds. In summary, a total of 133 worldwide studies that examined genetic diversity in local cattle, sheep, goat, chicken and pig ...
