Identidad ocupacional en docentes de carreras de la salud y su relación con las practicas pedagógicas

Background: Occupational identity is defined as the perception of occupational interests, abilities, goals, and values, and the structure of the meanings that link these self-perceptions to career role. We developed an occupational identity questionnaire suitable to be used with university teachers. Aim: To evaluate the psychometric properties of the Occupational Identity Questionnaire (OIQ) and relate its results with those of the Teaching Practices questionnaire. Material and Methods. The OIQ and Teaching Practices Questionnaire were answered by 311 university teachers along Chile, who were selected through a non-probabilistic volunteer sampling. An exploratory factor analysis was performed and the internal consistency of each factor was calculated with Cronbach’s Alpha. Spearman correlations were used to explore the relationship between the two questionnaires. Results: Two factors were identified in OIQ: Teaching Vocation and Sense of Competence. Cronbach’s Alpha was 0.75 for teaching vocation and 0.82 for the sense of competence. There was a moderate direct relationship between teaching vocation, sense of competence and the results of the Teaching Practices Questionnaire. Conclusions: OIS has an adequate internal consistency, its factorial structure showed two different types of identities and it is directly related to the results of the Teaching Practices Questionnair

Salinity tolerance ecophysiology of Equisetum giganteum in South America: a study of 11 sites providing a natural gradient of salinity stress

In river valleys of the world's driest desert (The Atacama of South America) large stands of giant horsetail (Equisetum giganteum) are found to tolerate soil water salinity up to at least half that of seawater. The roots selectively exclude Na and take-up K in response to salinity while stomatal conductances and photochemical efficiency of Photosystem II remain unaffected

A global experience‐sampling method study of well‐being during times of crisis: The CoCo project

We present a global experience-sampling method (ESM) study aimed at describing, predicting, and understanding individual differences in well-being during times of crisis such as the COVID-19 pandemic. This international ESM study is a collaborative effort of over 60 interdisciplinary researchers from around the world in the “Coping with Corona” (CoCo) project. The study comprises trait-, state-, and daily-level data of 7490 participants from over 20 countries (total ESM measurements = 207,263; total daily measurements = 73,295) collected between October 2021 and August 2022. We provide a brief overview of the theoretical background and aims of the study, present the applied methods (including a description of the study design, data collection procedures, data cleaning, and final sample), and discuss exemplary research questions to which these data can be applied. We end by inviting collaborations on the CoCo dataset

Efectos de la combinación de salinidad y exceso de boro en las relaciones hídricas del tomate (Solanum lycopersicum L.) tolerante cv. Poncho Negro y su relación con la funcionalidad de las acuaporinas

As elevated levels of boron (B) are accompanied by conditions of excessive salinity with drastic consequences for crops,it is crucial to find a crop that is tolerant to these conditions. In this work, the interaction between salinity and excess Bwith respect to aquaporin-mediated changes by blockade of mercury and water relations were studied as well as the osmotic adjustment of the plants. The treatments, for tomato ‘Poncho Negro’ cultivated hydroponically in a controlled environment chamber, were control (75 and 150 mM) NaCl and/or 5 mg L–1 or 20 mg L–1 B. Hydraulic conductance (L0) of detached exuding root systems exhibits large variations in response to abiotic stimuli. No additive (synergic) effects of B and salinity were observed. Under salinity, the plants increased their turgor, compensating for the decrease in the leaf water potential through the reduction in the leaf osmotic potential by the accumulation of soluble sugars and proline. The involvement of Hg2+-insensitive aquaporins or the osmotic gradient as the main force for water flow through the apoplastic pathway must be contemplated. Finally, all the data reveal the tomato cv. Poncho Negro to be a germplasm of agronomic interest and a good alternative for cultivation areas with high content of salts and the excess B of the soil and irrigation water.En muchas ocasiones niveles elevados de boro (B) van acompañados de condiciones de excesiva salinidad, cuyasconsecuencias pueden ser drásticas para los cultivos, por lo que es fundamental encontrar variedades que puedan tolerarestas condiciones. En este trabajo, se estudió cómo la interacción entre la salinidad y el exceso de B afecta a laactividad de las acuaporinas y a las relaciones hídricas, así como al ajuste osmótico de las plantas. Se cultivó en hidroponíatomate cv Poncho Negro en una cámara de crecimiento con ambiente controlado con los tratamientos control, NaCl (75 y 150 mM) y/o B (5 ó 20 mg L–1). No se observó ningún efecto aditivo (sinergia) del exceso de B y lasalinidad. Las plantas aumentaron su turgencia en condiciones salinas, compensando así la disminución del potencial hídrico foliar, a través de la reducción de su potencial osmótico por la acumulación de azúcares solubles y prolina. La participación de acuaporinas insensibles al Hg+2 o del gradiente osmótico, como la principal fuerza impulsora del flujo del agua, a través de la vía apoplástica, deben ser contemplados. Finalmente, todos los datos revelan que el tomate cv. Poncho Negro puede ser un germoplasma de interés agronómico y una buena alternativa para cultivar en condiciones de alto contenido de sales y exceso de B del suelo y del agua de riego
