Understanding Dietary Diversity, Dietary Practices and Changes in Food Patterns in Marginalised Societies in Sri Lanka
(2020-11-13)
Micronutrient malnutrition is a serious public health problem in developing countries, including Sri Lanka. Most frequently, micronutrient malnutrition is experienced by the poorest households due to cereal-based, monotonous diets that lack dietary diversity. Sri Lankan traditional food system is changing day by day. In parallel, nutrition deficiencies, malnutrition, and noncommunicable diseases are the most significant problems today in Sri Lanka. Therefore, understanding dietary diversity and dietary changes in Sri ...

Business model innovation in strategic alliances: a multi‐layer perspective
(2020-04-17)
Business model innovation (BMI) has recently become a topic of interest for research as well as corporate practice. However, we lack specific insights into actors, drivers, and different forms of BMI as the concept is by now mainly addressed in a very general way. In this paper, we analyze how BMI takes place in strategic alliances with the focus of enhancing the recent knowledge about BMI by developing a concept that links firm‐level BMI with alliance‐driven innovation of business models. Against the background of ...

Effect of Surfactants on the Flow Patterns of Horizontal Tube Bundles with a Falling Film
(2020-03-24)
The influence of two alcoholic surfactants on the flow patterns of falling film tube bundles is investigated. The flow patterns are measured in a single‐stage absorption chiller in the absence of surfactants. The surface tension of H2O/aqueous LiBr solution with different concentrations of 1‐octanol and 2‐ethylhexanol is measured at low pressure in a saturated atmosphere. Small quantities of surfactants in the aqueous solution do not have an influence on the flow patterns of the condenser and evaporator, while a shift ...

Exploration of production conditions: a step towards the development of a community-based breeding program for Butana cattle
(2020-11-17)
In Sudan, many Butana cattle farmers practice indiscriminate crossbreeding to improve the milk yield performance of cows, as organized breeding programs are lacking. Objectives of this study were to identify the current production conditions of Butana cattle and to determine farmers’ production objectives and trait preferences using a field survey. The overall aim was to explore the possibility of establishing a community-based breeding program for the genetic improvement of the breed. A semi-structured questionnaire ...

Sozialpolitik als Problemarbeit an Menschen und an Institutionen
(2020-10-28)
In der Soziologie sozialer Probleme ist Sozialpolitik seit jeher ein wichtiger Aspekt, wird aber nur selten explizit in den Mittelpunkt gestellt. Der Beitrag verdeutlicht die Relevanz von Sozialpolitik sowie ihrer organisationalen und professionellen Bezugspunkte (Wohlfahrtspflege, soziale Dienstleistungsberufe) im Kontext der Soziologie sozialer Probleme und nimmt eine Einordnung im Rahmen unterschiedlicher institutioneller Logiken vor. Mit Blick auf das Wechselspiel von Definitions- und Bearbeitungsprozessen ‚von ...

Additive surface texturing of cutting tools using pulsed laser implantation with hard ceramic particles
(2020-09-15)
In recent years surface texturing of the cutting tools has proved to improve tribological characteristics at tool/chip and tool/workpiece interface and help to reduce cutting and feed forces as well as tool wear. Most, if not all, of the studies have focused on subtractively made textures whereby the material is removed from the surface. This study investigates the performance of additively made surface structures whereby hard ceramic particles are dispersed in the form of dome shaped textures on the surface of the ...

Consumers’ Emotion Attitudes towards Organic and Conventional Food: A Comparison Study of Emotional Profiling and Self-Reported Method
(2020-01-10)
Emotions represent a major driver behind a consumption behavior. It may provide more important information beyond consumers’ preferences. This study contributes to a better understanding of the discrepancy in emotion attitudes towards organic versus conventional food using a cognitive survey and real food consumption experience. An emotional profiling under informed and uninformed condition, a cognitive survey, and a rapid forced-choice test were carried out with 46 consumers. Our work detected a yawning gap in ...

Vegetable Crop Biomass Estimation Using Hyperspectral and RGB 3D UAV Data
(2020-10-19)
Remote sensing (RS) has been an e ective tool to monitor agricultural production systems, but for vegetable crops, precision agriculture has received less interest to date. The objective of this study was to test the predictive performance of two types of RS data—crop height information derived from point clouds based on RGB UAV data, and reflectance information from terrestrial hyperspectral imagery—to predict fresh matter yield (FMY) for three vegetable crops (eggplant, tomato, and cabbage). The study was conducted ...
