The increasing cultural diversity in the current Spanish educational system has had dramatic consequences for school population demography and relationships between students in culturally diverse classrooms. In this context, the development of students' intercultural competence can contribute to strengthening communication, as well as preventing misunderstandings and coexistence problems. In this study, the effects of a teacher-led intercultural tutoring action programme (TAP) on elementary students' intercultural competence (IC) were assessed as a function of treatment condition and grade level. Participants were 187 third- to sixth-grade pupils (84% Spaniards and 16% immigrants) who were assigned randomly to treatment conditions (TAP versus comparison). After 20 weeks of programme implementation, the findings revealed that the TAP was successful. Conceptual intercultural competence was better achieved by fifth- to sixth-grade students, while IC skills and attitudes were significantly better developed by third- to fourth-grade students. Implications for teachers and counsellors/schools psychologists are discussed.

The potato is one of the main agricultural products in Colombia and is the second most important crop in the country. The production of this tuber represents 3.3% of the country's agricultural gross domestic product (GDP). More than 100,000 producer families subsist on cultivation at the national level, the vast majority of which are smallholdings. However, smallholders are not able to exploit the full potential of this activity, and one of the main factors that does not allow for improving productivity is the inefficient use of land in agricultural activities. This leads to issues such as erosion, overexploitation of soil resources, reduced productivity, and, depending on the time of year, even an excess of potato supply. Therefore, a multicriteria methodology is proposed based on the key elements of the potato crop production cycle and its environment, made up of farmers from the municipality of Ventaquemada, located in Boyacá, where potato cultivation is a traditional practice. This department is the second-largest potato-producing department in the country. A review of the literature was carried out to determine and characterise the area of the selected department, and based on the above, the relevant criteria were defined and the alternatives to be evaluated were identified. Second, the proposed model is evaluated with its respective prioritisation process of both the criteria and the alternatives according to the analytic hierarchy process (AHP) methodology. Finally, the results of the model are presented, prioritizing the type of tillage, irrigation method, seed type, and its disinfection process for potato cultivation. This takes into account topographic and climatic conditions, the ecosystem, soil type, implementation costs, among other factors specific to the case study. [ABSTRACT FROM AUTHOR]

Cocoa liquor is the primary precursor of the worldwide highly appreciated commodity chocolate. Its quality depends on several factors, such as the type of cocoa, the fermentation process, and the control of the contaminants in the fermented beans. This study aims to evaluate whether the induced magnetic field treatment during the fermentation process or the pathogen reduction with gamma irradiation after the fermentation affect the characteristics of the cocoa liquor obtained from Ecuadorian cocoa beans. For this purpose, liquor samples from controls (standard process), from beans treated with an induced magnetic field up to 80 mT, and from beans irradiated with nominal doses up to 3 kGy were characterized through Raman spectroscopic analysis and sensorial evaluation. The most relevant bands of the cocoa liquor were assigned according to reports from the literature, spectroscopic data, and chemometrics. The spectra corresponding to different treatments and doses were visually very similar, but they could be discriminated using OPLS-DA models, where the most intense Raman signals were attributed to the lipid components. The sensorial evaluation rated the presence of floral, fruity, almondy, acid, and bitter flavors, along with astringency and intense aroma, and these attributes exhibited variable behavior depending on the dose of the irradiation or magnetic treatment. Therefore, both treatments may exert an influence on cocoa beans and, therefore, on the cocoa liquor quality. [ABSTRACT FROM AUTHOR]

The purpose of this study was to examine the effect of an information and communications technology (ICT)-based individualised music education programme on primary students' musical competence. A 2 × 3 aptitude treatment interaction factorial design was used to assess the impact of the programme as a function of students' musical aptitude (MA) (low-average-high) and type of intervention (experimental vs. control). Participants were a convenient sample of 90 fifth- and sixth-grade students drawn from one public primary school in Albacete, Spain. Results indicated that average and high musically able participants developed a significantly higher competence in audition, vocal expression, instrumental expression, musical language, movement and dance, as well as in arts and culture in the ICT-based than in the non-ICT-based programme, while those with low MA appeared to benefit more from the non-ICT-based programme suggesting that students responded differently to the two types of interventions. Results are discussed in terms of implications to better adapt music teaching for student diversity.

-Soil compaction in cropping systems, caused by the external pressure of machinery, creates impermeable layers that restrict water and nutrient cycles reducing agricultural production. To evaluate the matric suction effects on distribution with depth of stresses in a soil, caused by the use of agricultural machinery, Jet Fill tensiometers were installed at two different depths (i.e. 0.15 m, 0.30 m) in a soil profile constituted by silty sand with gravel (SM); to register the increments on subsoil vertical stresses, two miniaturized load cells (i.e. 16. 5 mm in diameter) were installed in a horizontal position under the centre line of the vehicle wheels’ path, at approximately 0.15 m and 0.30 m depth. Care was taken to calibrate the load cells in field conditions. A vehicle was made to pass over the soil surface, at a speed less than 5 km/h; the tyre inflation pressure applied on wheel was 380 kPa. Response of load cells to vehicle loading was evaluated at different average matric suction measured on soil profile. Finally, measured stresses have been compared with values obtained by applying well-known elastic theoretical methods used to assess stresses applied by tyres on bare soils. The corresponding results show that the increment of vertical stresses decreases as matric suction increases, and a good correlation between measurements and simulations of the increment on subsoil vertical stress.
