    Converging pathways: new approaches to integrate vocational education training and higher education
    (Routledge, 2024-11-14) Farrán Blanch, Inmaculada; Núñez Aldaz, Imanol; Institute for Advanced Research in Business and Economics - INARBE; Institute for Multidisciplinary Research in Applied Biology - IMAB
    The evolving professional landscape necessitates educational innovation to prepare students for emerging challenges. This paper explores the integration of Vocational Education and Training (VET) and Higher Education (HE) through double-degree programs, challenging the conventional perception of these pathways as independent. Recognising the transformative potential in synergising competencies from VET and HE, we advocate for enhancing students' employability through collaborative curriculum design and shared learning objectives. Addressing limitations in the current VET-to-HE transition, we identify four criteria for successful double programs (i) coherent competency map, (ii) unified methodology, (iii) distinctive profile, (iv) own signalling. The paper concludes with a case study of an emerging dual VET/HE program in Navarra (Spain) built on the criteria outlined above.

    Plant ammonium sensitivity is associated with external pH adaptation, repertoire of nitrogen transporters, and nitrogen requirement

    Modern crops exhibit diverse sensitivities to ammonium as the primary nitrogen source, influenced by environmental factors such as external pH and nutrient availability. Despite its significance, there is currently no systematic classification of plant species based on their ammonium sensitivity. We conducted a meta-analysis of 50 plant species and present a new classification method based on the comparison of fresh biomass obtained under ammonium and nitrate nutrition. The classification uses the natural logarithm of the biomass ratio as the size effect indicator of ammonium sensitivity. This numerical parameter is associated with critical factors for nitrogen demand and form preference, such as Ellenberg indicators and the repertoire of nitrogen transporters for ammonium and nitrate uptake. Finally, a comparative analysis of the developmental and metabolic responses, including hormonal balance, is conducted in two species with divergent ammonium sensitivity values in the classification. Results indicate that nitrate has a key role in counteracting ammonium toxicity in species with a higher abundance of genes encoding NRT2-type proteins and fewer of those encoding the AMT2-type proteins. Additionally, the study demonstrates the reliability of the phytohormone balance and methylglyoxal content as indicators for anticipating ammonium toxicity. This study emphasizes the importance of ecophysiological requirements and the repertoire of nitrogen transporters in understanding plant sensitivity to ammonium, and enhances our knowledge of plant nitrogen nutrition.
