Gendering post-harvest loss research: responsibilities of women and men to manage maize after harvest in southwestern Ethiopia
(2022-03-22)
Post-harvest losses are a significant problem worldwide, leading to a waste of resources when they are becoming scarcer. Rather than putting more energy into increasing production volume, addressing post-harvest losses can increase food availability without increasing yields. Using maize in Ethiopia to introduce gendering post-harvest loss research, we analyze the gendered division of labor in post-harvest management and then discuss implications. The study was conducted from 2014–2015 in southwestern Ethiopia as ...

Seasonal Variations in Voluntary Intake and ApparentDigestibility of Forages by Goats in the Chinese Altai Mountains
(2022-06-27)
Forage availability and quality directly impact animal performance, ultimately affecting productivity and health. This study aimed to understand the interaction between qualitative and quantitative vegetation availability and feed intake of goats on alpine pastures in the Chinese Altai Mountains. The daily grazing routes of three goats from a local herding family were monitored with GPS devices set at a logging rate of 64 s during spring and the early and late summer season in 2013 and 2014. The quantity and quality ...

Agronomic performance of normal-leafed and semi-leafless pea (Pisum sativum L.) genotypes
(2022-03-30)
Pea (Pisum sativum L.) is a major pulse crop important as feed and food. Due to the symbiosis with N-fixing bacteria, it is a valuable component of low-input cropping systems. The traditional cultivation of peas was limited by their high susceptibility to lodging. This problem was reduced, though not completely solved, by a semi-leafless mutant. Almost all modern cultivars carry this mutant. It is still an open question as to whether the lack of leaflets may have impaired the productivity. In organic farming, there ...

Von sub\urban zu Pro:Polis?
(2022-06-22)
Die Jubiläumsausgabe von sub\urban widmet sich unter dem Titel „sub\x“ vor allem aktuellen Positionen des Urbanen. Dieser Beitrag hingegen widmet sich vor allem möglichen Alternativen des sub, das die Perspektive der Redaktion auf das Städtische beschreibt. Aus dem Sub wird ein Trans, ein Re, ein Pro, ein Post und ein Ko. Mit jeder Veränderung der Vorsilbe – und damit des Blickwinkels auf das Urbane – tritt ein anderer Aspekt der Stadt und des Städtischen, der Stadtproduktion und -planung sowie nicht zuletzt der ...

Balancing Trade-Offs in Milk Production by Making Use of Animal Individual Energy Balancing
(2022-05-17)
Traditionally, the energy supply of dairy cows is based on the average performance of the herd. Because this contradicts the great variation in requirements between individual animals, the objective of the present study was to quantify both the extent and consequences of variation in the relevant sub-variables used to calculate the energy balance (EB) on an individual animal basis. Total energy supply (TES) and requirements (TER) of 28 multiparous German Holstein dairy cows fed TMR with 7.0 MJ NEL were studied between ...

The many faces of Post-Development: alternatives to development in Tanzania, Iran and Haiti
(2022-06-21)
Post-Development, a body of transitional imaginaries, is not homogenous, neither in its critique, nor in the alternatives proposed. Given that the term ‘development’ is already highly contentious, the question of what ‘alternatives to development’ might be, becomes difficult to respond to. In this article, we argue that Post-Development can assume many faces that are highly dependent upon their conceptual and geographical contexts. In analysing practices of resistance, contestation and subversion in Tanzania, Iran ...

Should I Stay or Should I Go? Risk Perception and Use of Local Public Transport During the COVID-19 Pandemic
(2022-07-07)
In light of the climate crisis, the transport sector needs to be urgently transformed and the number of users of local public transport needs to be increased. However, the first year of the COVID-19 pandemic severely affected public transport with passenger numbers declining up to 80% in Germany. In addition to a general decrease in mobility during lockdowns, we can observe a shift in decision-making in regards to modes of transportation, with public transport losing out. We argue that this change in behavior can be ...

Virtual Reality Experience of Mega Sports Events: A Technology Acceptance Study
(2022-05-24)
Digitalization has advanced to become an opportunity to spectate sports during the pandemic and its restrictions for traveling to competitions. The purpose of this study is to investigate the antecedents of using virtual reality technology for spectating mega sports events. Based on a literature review, the authors created a model of behavioral intention, built on the unified theory of acceptance and use of technology and technology acceptance model to examine the curiosity and self-construal of spectators. An online ...

Determination of Local Electrical Properties Using a Potential Field Measurement for Electrically Conductive Carbon Fiber Reinforced Plastics with Metal Contact Pins Joined via Injection Molding
(2022-07-09)
Carbon fiber reinforced plastics (CFRP) bear a high potential in terms of electrical conductivity and its potential applications. A locally resolved electrical measurement method for these anisotropic materials is a key prerequisite for understanding the structural and manufacturing process-related interrelationships. The aim of this paper is to develop a measurement method that allows this to be achieved and also to investigate areas of overmolded metal contact pins in detail. CFRP samples with polyamide 6 and ...

Botanical concrete
(2022-06-30)
La ricerca sul Botanical Concrete indaga con un approccio innovativo, basato sul design thinking, i materiali e la fitotecnologia, nei sistemi di inverdimento per pareti al fine di dare nuove funzioni al calcestruzzo e consentire l’insediamento superficiale permanente contemporaneamente di crittogame e tracheofite, due specie con diverse esigenze di substrato che si traducono in due distinti requisiti del calcestruzzo. Dalla combinazione dei risultati delle sperimentazioni sulle crittogame e sulle tracheofite si ...
