How do consumers search for and process corporate social responsibility information on food companies’ websites?
(2019-01-03)
The importance of corporate social responsibility (CSR) communication for food companies has grown substantially ever since global action plans such as the UN Sustainable Development Goals have begun targeting topics which are highly relevant to food companies. Furthermore, various food scandals have caused consumers to question current food production methods, leading to a search for more information on ethical production methods. However, it is not known how consumers search for and process information on websites ...

Human and farm influences on dairy cows' responsiveness towards humans - a cross-sectional study
(2018-12-31)
The human-animal relationship can have a major impact on cow welfare and stockpersons´ work safety and quality. This cross-sectional study investigated possible effects of stockperson and farm related factors on cows´ behaviour towards humans in different test situations on a range of farm types including farms with automatic milking system. On 32 dairy farms, cows´ avoidance distances (AD), tolerance to tactile interactions (TTI), behavioural reactions during and after release from restraint (RB) and expressive ...

Hydraulic Mission at Home, Hydraulic Mission abroad? Examining Turkey’s Regional ‘Pax-Aquarum’ and Its Limits
(2019-01-04)
Water resource development has always been considered as a strategic tool by the Turkish ruling elites to reach food and energy security, as well as to enhance domestic peace and stability since the foundation of the Republic of Turkey. Therefore, the concept of “hydraulic mission” fits this strategic understanding, and it has become a prevailing paradigm in Turkey’s water resource development. Many academic works have already been conducted to understand how Turkey has waged an ambitious hydraulic mission by ...

Editorial
(2020-12-21)
Der „Blickpunkt“ dieser Ausgabe widmet sich unter dem Titel „Zusammenhalt | diferença“ also Fragen, die die Möglichkeiten, gesellschaftlichen Zusammenhalt herzustellen, unter Beachtung sozialer Ungleichheiten und Differenz diskutieren. Dabei wird der Blick gerichtet auf Brasilien und eine Praxis, die sich wesentlich
dokumentiert in den dortigen sozialen Bewegungen und den über diese initiierten Formen der Herstellung von sozialen Kontexten.

Effects of Water Quality and Post-Harvest Handling on Microbiological Contamination of Lettuce at Urban and Peri-Urban Locations of Ouagadougou, Burkina Faso
(2018-12-16)
Vegetable production in urban gardens of Ouagadougou contributes to food security, but water for irrigation is often of low quality. This is particularly acute if irrigation water is taken from wastewater polluted channels. This study aimed at (i) verifying to what degree irrigation water quality is correlated with contamination of lettuce with Escherichia coli, total coliforms, and Salmonella spp., and (ii) assessing effects of post-harvest handling on pathogen development during the trade chain. We tested pathogen ...

Extended life cycle assessment reveals the spatially-explicit water scarcity footprint of a lithium-ion battery storage
(2021-01-12)
The life cycle water scarcity footprint is a tool to evaluate anthropogenic contributions to regional water scarcity along global supply chains. Here, we complement it by a classification of the risk from human water use, a comprehensive conceptualisation of water use and a spatially-explicit impact assessment to a midpoint approach that assesses the risk of on-site and remote freshwater scarcity. For a 2 MWh Lithium-ion battery storage, the quantitative Water Scarcity Footprint, comprising physically used water, ...

The Diacylglycerol Analogs OAG and DOG Differentially Affect Primary Events of Pheromone Transduction in the Hawkmoth Manduca sexta in a Zeitgebertime-Dependent Manner Apparently Targeting TRP Channels
(2018-07-24)
For the hawkmoth Manduca sexta accumulating evidence suggests that pheromone transduction acts via a metabotropic signal transduction cascade, with G-protein-dependent phospholipase C (PLC) activations generating diacylglycerol (DAG) and inositol trisphosphate as the primary events in hawkmoth pheromone transduction. In contrast, ionotropic olfactory receptor (OR) coreceptor (Orco)-dependent mechanisms do not appear to be involved. In hawkmoths pheromones activated a specific sequence of PLC-dependent ion channels ...

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 ...

SSPIM: a beam shaping toolbox for structured selective plane illumination microscopy
(2018-07-03)
Selective plane illumination microscopy (SPIM) represents a preferred method in dynamic tissue imaging, because it combines high spatiotemporal resolution with low phototoxicity. The OpenSPIM system was developed to provide an accessible and flexible microscope set-up for non-specialist users. Here, we report Structured SPIM (SSPIM), which offers an open-source, user-friendly and compact toolbox for beam shaping to be applied within the OpenSPIM platform. SSPIM is able to generate digital patterns for a wide range ...

High-Purity Triggered Single-Photon Emission from Symmetric Single InAs/InP Quantum Dots around the Telecom C-Band Window
(2019-11-07)
The authors demonstrate pure triggered single‐photon emission from quantum dots (QDs) around the telecommunication C‐band window, with characteristics preserved under non‐resonant excitation at saturation, that is, the highest possible, lifetime‐limited emission rates. The direct measurement of emission dynamics reveals photoluminescence decay times in the range of (1.7–1.8) ns corresponding to maximal photon generation rates exceeding 0.5 GHz. The measurements of the second‐order correlation function exhibit, for ...
