Emerging Development Pathways of Urban Livestock Production in Rapidly Growing West Africa Cities
(2016-11-19)
In this study, we try to capture the degree of specialization or integration, and of intensification or extensification, of (peri-) urban livestock production, along with the factors that influence such decisions and their impact on natural resource uses. A total of 181 and 187 structured questionnaires were completed in livestock-keeping households in Ouagadougou (Burkina Faso) and Tamale (Ghana). Categorical principal component and two-step cluster analysis were used to identify homogenous groups of livestock-keeping ...

Distributed practice in mathematics: Recommendable especially for students on a medium performance level?
(2019-10-24)
In this study, the effect of distributed practice on the mathematical performance of 7th graders was investigated (N == 81). After a stochastics lesson, one group of students worked three sets of exercises massed on one day, while the other group of students worked the same exercises distributed over three days. Bayesian analyses of the performance two weeks after the last practice revealed no evidence for an effect of practice condition. However, in a test after six weeks, strong evidence for a positive effect of ...

Optimising beekeeping development programs for improved productivity, income and welfare: a case study of Papua New Guinea
(2020-10-19)
Beekeeping can provide important sources of cash income for farmers in developing countries where land is unconducive to crop and livestock production systems. In many low-income countries however, attrition among beekeeping adopters remains a chronic problem, colony losses are high, support for and coordination of the sector is low, and practices, production and income from beekeeping is often inefficient. This study investigated the key drivers and practices influencing incomes from beekeeping, honey production and ...

Signal based non-intrusive load decomposition
(2019-05-29)
Driven by both regulatory and monetary interests the development of energy monitoring systems has been accelerated in recent years. Thus, a large amount of data is collected and stored in huge databases. This is a decisive step towards sustainable production systems since you can’t improve what you don’t know. This paper aims to use the datasets currently available and to combine databases to gather additional information on production systems, in particular energy flows. Therefore, an algorithm has been developed ...

Factors driving adoption and constraining the non-adoption of biofortified orange fleshed sweet potatoes (OFSP) among farmers in Abia State, Nigeria
(2020-09-22)
This study sought to determine the factors that drive the adoption and constrain the non-adoption of Orange Fleshed Sweet Potato (OFSP) varieties among farmers in Abia State, Nigeria. Multistage sampling procedure was used in selecting sixty sweet potato farmers (thirty adopters and non-adopters each). Participatory tools such as structured interview schedule, key informant interviews and personal observation were employed for quantitative and qualitative data collection. The data were analysed using descriptive ...

Mental rotation and the human body: Children's inflexible use of embodiment mirrors that of adults
(2018)
Adults’ mental rotation performance with body‐like stimuli is enhanced if these stimuli are anatomically compatible with a human body, but decreased by anatomically incompatible stimuli. In this study, we investigated these effects for kindergartners and first‐graders: When asked to mentally rotate cube configurations attached with human body parts in an anatomically compatible way, allowing for the projection of a human body, children performed better than with pure cube combinations. By contrast, when body parts ...

Drivers of farmers market participation in southeast Nigeria
(2020-10-29)
The objective of this paper was to investigate the drivers of farmers’ participation in the output market for yellow pepper using a sample of 420 randomly selected producers from 8,500 farmers in selected markets in southeast Nigeria. The heterogeneity of smallholder market participation was modelled with quantile regression. The variables that affected all the quantiles (i.e. for subsistence, semi-subsistence, intermediate, semi-commercial and commercially oriented farms) are the distance to the trading centre and ...

Deiktika in altspanischen Texten
(2010-09)
La présente contribution montre à l’exemple de déictiques dans des textes de l’espagnol médiéval comment les fonctions des langues particulières et les traditions discursives sont imbriquées les unes dans les autres. Concernant les déictiques, nous sommes d’avis que la polyfonctionnalité, c’est-à-dire la coexistence synchronique de fonctions indexicales et non-indexicales, est une caractéristique des déictiques en espagnol médiéval (et des langues romanes en général). Afin d’établir des relations précises et systématiques ...

Die Vergütung nichtärztlicher Leistungen Sozialpädiatrischer Zentren
(2019)
Die Vergütung nichtärztlicher sozialpädiatrischer Leistungen Sozialpädiatrischer Zentren ist seit langem ein streitträchtiges Thema. In jüngster Zeit beschäftigt das Thema immer wieder die zuständigen Schiedsstellen, und im vergangenen Jahr wurde eine längere Auseinandersetzung durch ein Urteil des LSG Berlin-Brandenburg zum Abschluss gebracht. Dieses Urteil soll im folgenden Aufsatz analysiert werden.

Household food wastage in Albania: causes, extent and implications
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2020-04-02)
Food waste (FW) is a very serious issue not only in ethical and social terms, but also given its economic and environmental impacts (cf. resource wastage and depletion). Recent data show that more than half of food wastage in the European Union is generated in households. FW is unfortunately not well addressed in Albania. For this reason, an exploratory online survey was carried out in the period August–November 2016 with 185 Albanians to analyse the causes, extent and implications of household food wastage in Albania. ...
