Food typology of traditional foods based on millet, sorghum and cowpea from the rural communes of north central region of Burkina Faso
(2023-07-31)
Food vulnerability is a growing plague in developing countries, neglecting local foods. Better knowledge of local foods is necessary to improve their consumption. The objective of this study is to identify the types of local millet, sorghum and cowpea foods in the North Central Region from a socio-cultural perspective. The methodology consisted of organizing 12 focus groups to respond to an individual questionnaire on the socio-cultural characteristics of participants and their knowledge of their millet, sorghum and ...

Female farmers in the Galapagos: An invisible force
(2023-11-07)
Despite the crucial contributions of women to agriculture and food security, female farmers in the Galapagos Islands face persistent challenges that hinder the recognition and valuation of their work. Furthermore, the lack of gender-disaggregated data tailored to their local and contextual realities presents an ongoing challenge for evidence-based policy formulation, hampering the response to their specific needs and challenges. Taking a departure from the dominant quantitative approach in agricultural research, this ...

Influence of Surface Mechanical Attrition Treatment (SMAT) on Microstructure, Tensile and Low-Cycle Fatigue Behavior of Additively Manufactured Stainless Steel 316L
(2023-08-29)
Direct Energy Deposition (DED), as one common type of additive manufacturing, is capable of fabricating metallic components close to net-shape with complex geometry. Surface mechanical attrition treatment (SMAT) is an advanced surface treatment technology which is able to yield a nanostructured surface layer characterized by compressive residual stresses and work hardening, thereby improving the fatigue performances of metallic specimens. In the present study, stainless steel 316L specimens were fabricated by DED and ...

Cooperatives as instruments of smallholder development: Evidence from banana, cocoa, coffee, and palm oil producers in Peru
(2023-11)
Collective action in the agricultural sector of Peru started in the form of agrarian production cooperatives around 1969. Following the collapse of the collectivisation program in the 1980s, external stakeholders helped to form marketing cooperatives in select sectors to discourage coca leaf production. Nowadays, cooperatives are only active in four sectors: banana, cocoa, coffee, and palm oil. Case study evidence of the performance of cooperatives in Peru is mixed, which raises the need for applied research to inform ...

Newly implemented crop-livestock-forest systems increase available water and aeration in soils of the Brazilian Savannah
(2023-11-21)
There is a growing demand for cropping systems that guarantee food production by improving the use efficiency of natural resources such as soil and water. The crop-livestock-forest (CLF) system is a form of sustainable intensification in which biodiversity and yields are increased on the same area. In this study, the physical-hydric properties of a Ferralsol and Cambisol in Central Brazil within the Savannah biome (Cerrado) were investigated 2 and 1 year after implementation of CLF systems. Soil samples were collected ...

Exploring the non-genetic factors that affect reproductive traits of Saanen goats in Indonesia
(2023-11)
Adjustment of trait records for different non-genetic factors increases the accuracy of genetic parameters and enables more accurate selection. This study aimed to investigate the non-genetic factors affecting reproductive traits in Saanen goats at the Baturraden breeding centre, Indonesia. The data of 71 Saanen does from the years 2014 to 2021 consisted of reproductive traits, namely, total birth weight (TBW), age at first kidding (AFK), kidding interval (KI), litter size (LS), multiple birth rate (MBR) and kidding ...

Wünschenswerte Erschwernisse beim Lernen
(2015)
Der Beitrag beleuchtet didaktische Maßnahmen, die unter dem Begriff „Wünschenswerte Erschwernisse“ zusammengefasst werden. Diese Maßnahmen erschweren zwar kurzfristig das Lernen, langfristig aber fördern sie das Behalten und den Transfer des Gelernten. Vier dieser wünschenswerten Erschwernisse sind empirisch besonders gut belegt: 1) Das verteilte Lernen, 2) das verschachtelte Lernen, 3) der Testungseffekt und 4) der Generierungseffekt. Zu jeder dieser wünschenswerten Erschwernisse werden aktuelle Forschungsergebnisse ...

Girls in detail, boys in shape: Gender differences when drawing cubes in depth
(2013)
The current study tested gender differences in the developmental transition from drawing cubes in two‐ versus three dimensions (3D), and investigated the underlying spatial abilities. Six‐ to nine‐year‐old children (N = 97) drew two occluding model cubes and solved several other spatial tasks. Girls more often unfolded the various sides of the cubes into a layout, also called diagrammatic cube drawing (object design detail). In girls, the best predictor for drawing the cubes was Mental Rotation Test (MRT) accuracy. ...

Between cripping and reclaiming
(2022)
Disability Studies promote different feeling strategies pushing for social change towards a more inclusive and less ableist society. There is a utopian touch to this: How can we change the world by feeling differently about disability? Disabled people have discussed how to navigate ableism’s emotional toll probably since the Disability Rights movement’s roots. The paper-at-hand oscillates between two strategies that Disability Studies scholars and activists have advocated for: Cripping – deliberately changing one’s ...

Shape But Not Color Facilitates Two-Year-Olds’ Search Performance in a Spatial Rotation Task
(2018)
Children younger than 3 years of age often fail to track hidden objects that are rotated together with identical hiding containers, which might be due to relatively complex paradigms. We examined whether 2-year-olds (N = 28) are already able to track spatial rotations (i.e., by 90° and 180°) if the task is facilitated by increasing the visual discriminability of the hiding containers by means of different shapes and different colors. Children performed above chance level in all conditions except for the condition in ...
