Concepciones de enseñanza y aprendizaje de profesores de infantil, primaria y secundaria y la relación con las variables educativas

It has been established that teachers' conceptions of learning and teaching influence their instructional practices. Several authors maintain that these conceptions are based on certain implicit assumptions that give rise to different theories. Our view is that people have multiple alternative theories which they use depending on the context and the demands of the task. The main purpose of this study was to find out whether such representational plurality exists in teachers' conceptions and, if it does, whether this plurality can lead to the identification of different representational profiles. We were also interested in studying some of the teaching practice variables that might influence the nature of the representational profiles. Our results, obtained by means of a dilemma questionnaire answered by 1074 teachers from different educational levels and knowledge domains and with different ranges of experience, are consistent with the assumption of representational plurality, as they show that the same teacher may hold different conceptions that set up a conceptions profile. Moreover, the combination of the responses in each profile is not random. Teachers at the more advanced levels and with more teaching experience manifested more traditional conceptions. Furthermore, some knowledge domains were associated with certain conception profilesSe ha comprobado que las concepciones de aprendizaje y enseñanza de los profesores influyen en su práctica docente. Varios autores sostienen que estas concepciones se basan en ciertos supuestos implícitos que dan lugar a distintas teorías. Nuestra visión es que la gente dispone de multitud de teorías alternativas que pueden utilizar en función del contexto y las exigencias de la tarea. El objetivo principal del presente estudio es averiguar si esta pluralidad representativa existe en las concepciones de los profesores y, de ser así, si puede conducir a la identificación de distintos perfiles representacionales. Nos interesamos, asimismo, por el estudio de algunas de las variables de la práctica docente que pudieran influir en la naturaleza de dichos perfiles. Nuestros resultados - obtenidos mediante un cuestionario de dilemas realizado por 1074 profesores de distintos niveles educativos, ámbitos de conocimiento y experiencia- coinciden con la suposición de la pluralidad representativa, pues revelan que el mismo profesor podría forjar concepciones distintas que conforman un perfil de concepciones. Además, la combinación de respuestas en cada perfil no es aleatoria. Los profesores de niveles más altos y los más experimentados manifestaron unas concepciones más tradicionales. Igualmente, algunos campos de conocimiento se asociaron a perfiles de concepciones concretosThis research was funded under three projects of the National Program for Basic Research-Projects by the Spanish Ministry of Science and Innovation (EDU2009- 14278-C02-01EDUC) (EDU2010-21995-C02-01) and (EDU2013-46606-C2-1-R)

Re-evaluating sheet erosion rates in a popular trekking trail located at the Spanish Central System

Degradation of walking tracks, mainly due to sheet erosion associated with hiking activities, damages the natural and recreational value of protected natural areas. Senda Schmidt is a popular trail located on the northern slope of the Sierra de Guadarrama (Central Spanish System), that shows high denudation morphologies on account of accelerated soil-erosion processes basically caused by human influence (trampling by continuous trekking), resulted in exposed roots. Previous works have used dendrogeomorphological methods in this trail to estimate rates of sheet erosion based on the changing morphology of tree rings (from concentric to eccentric) when root is exposed. This study aims to evaluate soil erosion reconstructing the first year of root exposure by analyzing changes in wood anatomical parameters within growth rings. Additionally, different multivariate statistical approaches were used in order to determinate the influence of different environmental factors affecting the variation in velocity of the sheet erosion processes

Innovative Health and Social Integrated Care Model Effectiveness to Improve Quality Care for Chronic Patients: A Single Group Assignment Clinical Trial

Background: Patients with chronic disease have become one of the major challenges for health and social protection systems in developed countries. Integrated care models (ICM) have demonstrably improved the quality of care of chronic patients. However, new models of integration need further evaluation of its effectiveness and outcomes. Methods: The ICM studied promoted coordination between the health and social sectors during a 6-month period, through an ad hoc developed application (app) that enabled a constant flow of communication between professionals from both sectors. Patients’ quality of life, treatment adherence, chronic patient experience and caregiver overload were assessed by questionnaires at baseline, at the end of the intervention and 6 months post-intervention. Results: The implementation of the new health and social ICM permitted new case detection and medical and social services offered to chronic patients. Furthermore, the quality of life and treatment adherence of patients and caregiver overload were significantly improved. These positive effects lasted at least 6 months after the intervention. Conclusions: Integrated care may facilitate access to care services, increase perceived patient quality of life and treatment adherence. Enhanced access to medical and social services from complex chronic patients may have important implications for caregivers and the care systems who are struggling to adapt to an expanding demand.   Resum Antecedents: Els pacients amb malalties cròniques representen un dels grans reptes per als sistemes de salut i protecció social als països desenvolupats. S’ha demostrat que l’atenció integrada millora la qualitat assistencial dels pacients crònics. Tanmateix, els resultats i l’efectivitat de nous models d’integració requereixen ser avaluats. Metodologia: El model d’atenció integrada d’estudi va promoure la coordinació entre els sectors sanitari i social durant un període de 6 mesos mitjançant una aplicació (app) desenvolupada ad hoc que permetia un flux constant de comunicació entre professionals d’ambdós sectors. La qualitat de vida dels pacients, l’adherència al tractament, l’experiència del pacient i la sobrecàrrega del cuidador es van avaluar mitjançant qüestionaris a l’inici, al final de la intervenció i 6 mesos després de la intervenció. Resultats: La implantació de l’atenció integrada social i sanitària va permetre la detecció de nous casos i un major accés dels pacients crònics als serveis mèdics i socials. A més, va millorar significativament la qualitat de vida i l’adherència al tractament dels pacients i la sobrecàrrega dels cuidadors. Aquests efectes positius van perdurar almenys 6 mesos després de la intervenció. Conclusions: L’atenció integrada pot facilitar l’accés als serveis assistencials, augmentar la qualitat de vida percebuda dels pacients i l’adherència al tractament. L’accés millorat als serveis mèdics i socials dels pacients crònics complexos pot tenir implicacions importants per als cuidadors i els sistemes assistencials que lluiten per adaptar-se a una demanda creixent.   Paraules Clau: Sistemes sanitaris integrats; malaltia crònica; qualitat de vida; implementació de programes; tecnologies de la informació i la comunicació (TIC

Nevertheless, age-related predictive factors of the waning humoral immune response to the vaccine have been scarcely explored. In a cohort of residents and healthcare workers from a nursing home that had received two doses of the BNT162b2 vaccine, we measured specific anti-S antibodies one (T1), four (T4), and eight (T8) months after receiving the second dose. Thymic-related functional markers, including thymic output, relative telomere length, and plasma thymosin-α1 levels, as well as immune cellular subsets, and biochemical and inflammatory biomarkers, were determined at T1, and tested for their associations with the magnitude of the vaccine response (T1) and the durability of such response both, at the short- (T1-T4) and the long-term (T1-T8). We aimed to identify age-related factors potentially associated with the magnitude and persistence of specific anti-S immunoglobulin G (IgG)-antibodies after COVID-19 vaccination in older people.[Results] Participants (100% men, n = 98), were subdivided into three groups: young (< 50 years-old), middle-age (50–65 years-old), and older (≥65 years-old). Older participants achieved lower antibody titers at T1 and experienced higher decreases in both the short- and long-term. In the entire cohort, while the magnitude of the initial response was mainly associated with the levels of homocysteine [β (95% CI); − 0.155 (− 0.241 to − 0.068); p = 0.001], the durability of such response at both, the short-term and the long-term were predicted by the levels of thymosin-α1 [− 0.168 (− 0.305 to − 0.031); p = 0.017, and − 0.123 (− 0.212 to − 0.034); p = 0.008, respectively].[Conclusions] Higher plasma levels of thymosin-α1 were associated with a lower waning of anti-S IgG antibodies along the time. Our results suggest that plasma levels of thymosin-α1 could be used as a biomarker for predicting the durability of the responses after COVID-19 vaccination, possibly allowing to personalize the administration of vaccine boosters.This work was supported by the Instituto de Salud Carlos III through the project “PI21/00357” (Co-funded by European Regional Development Fund/European Social Fund “A way to make Europe”/“Investing in your future”).
