Distributed practice in mathematics: Recommendable especially for students on a medium performance level?
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 ...
Signal based non-intrusive load decomposition
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 ...
Die Vergütung nichtärztlicher Leistungen Sozialpädiatrischer Zentren
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.
Comparison of decent work status among smallholder pig farmers in Kenya; An empirical approach using Principal Components
Agricultural production in Kenya is dominated by smallholder enterprises which provide up to 60% of the country's workforce. The agrarian transition to enhance smallholder participation in neoliberal capitalistic markets demands compliance to sanitary and phytosanitary standards and with codes for worker's welfare and thus the concept of decent work. Evaluation of decent work deficits in the informal economy however remains a challenge associated with sector uniqueness and differences in socio- cultural attributes ...
The eating culture of the Sundanese: Does the traditional salad (Lalapan) improve vegetable intake and blood β-carotene concentration?
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2019-09-12)
This study explores how consumption of the traditional salad Lalapan, central to the eating culture of the Sundanese, is associated with skin quality perception, daily β-carotene intake and blood β-carotene concentrations. This cross-sectional study was conducted in Gunung Malang Village and Leuweung Kolot Village, Bogor District, West Java. 60 healthy Sundanese women, aged 30-49 years, were selected using simple random sampling. Their body weight and height were measured, and they were interviewed about the eating ...
Distribution of Alternaria leaf blight of sunflowers caused by Alternaria alternata in South Africa
Alternaria leaf blight (ALB) has been shown in recent years to be one of the major potential disease threats of sunflower capable of causing yield losses in all major production areas. The aim of this study was to determine the causal agent, prevalence and geographical distribution of ALB in the major sunflower production areas of South Africa. Surveys were conducted during 2012/13, 2013/14 and 2014/15 growing seasons at commercial sunflower production fields and at commercial cultivar trials. In the three growing ...
Biological control in pest management in Turkey: Comparison of the attributes of participant and non-participant greenhouse farmers in government-subsidized biological control practices
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2019-11-29)
The adoption of biological control methods is increasing in crop production due to concerns and awareness of consumers about food safety and pesticide residue conundrum. Biological control methods are a key component in pest management practices as they minimize the usage of pesticides, hence create less environmental and health problems. Biological control practices have been supported in Turkey since the year 2010 to ensure economical greenhouse production and to reduce the consumption of pesticides for sustainable ...
Open field screening of the productive parameters, protein content, phenolic compounds, and antioxidant capacity of maize (Zea mays L.) in the marginal uplands of southern Madagascar
Madagascar is recognised as having both a high level of poverty and a food shortage. The contribution of the agricultural sector to the national income is higher than for any other sector, though this sector remains insufficiently developed to sustain national food demand. In order to increase food production, the diversification of staple food in conjunction with the detection of best-yield genotypes may be considered the simplest and least expensive alternative approach. For this reason, the response of productive ...
Understanding the emergence and evolution of pastoral community groups from the perspective of community members and external development actors in northern Kenya
(Kassel University Press, 2019-01-15)
Whereas there is abundance of information on community groups that engage in income generation in rural agricultural and peri-urban areas, information on community groups in pastoral areas still remains scarce. However, in the recent past, a growing trend of such groups has been observed in the pastoral areas in northern Kenya. This study therefore explores how these groups have emerged since Kenya’s independence in 1963 to date, and which factors have contributed to their evolution. A full survey on all income-generating ...
Effect of salt stress on muskmelon (Cucumis melo L.) seeds
Cucumis melo is one of the most appreciated and consumed vegetables in the world, however, producing areas have been suffering from increased salinity in irrigation water. Therefore, accesses of melon, from the germplasm bank of the Federal Rural Semi-Arid University (UFERSA), were tested for salinity and the physiological responses of the seedlings were evaluated. For the 24 accesses of C. melo, salinity of 0.06 and 3.45 dS m-1 was applied. For this, four subsamples of 25 seeds per access were used, which were seeded ...
