Diseño y desarrollo de un material didáctico para entornos virtuales de aprendizaje de funciones lineales matemáticas

La oferta de formación virtual y el uso de recursos e-learning ha ganado potencial en la masificación e internacionalización de la educación superior, no obstante, se ha determinado que existen limitaciones y desventajas tanto en aspectos técnicos como en las metodologías y diseño por parte de estos contenidos en la enseñanza y aprendizaje. La presente investigación, busca comprender la apreciación e incidencia de recursos didácticos virtuales mediante el uso de herramientas tecnológicas y propone el diseño de un recurso didáctico para el aprendizaje de funciones lineales para el aprendizaje de las matemáticas en la educación superior

Metodología para la evaluación de recursos digitales bibliográficos: experiencia del G8 Bibliotecas, Antioquia.

This article describes the collaborative experience of G8 Library Group of Medellin City in the elaboration of the Technical Matrix for the assessment of Bibliographic Databases and digital resources. Its purpose is serving as a reference to other institutions of the same nature. It is highlighted the importance of having a permanent and systematic evaluation too for decision making regarding the subscription or purchasing of digital resources, bibliographic databases, discoverers and statistical software. The Matrix categories and its reference value are established on 100 points: Search (20), Access (15), Utilities and tools (15), Administration module (10) and Interface (5). In turn, factors and categories with their respective assigned scores are derived from these categories, to later assign the grade and finally obtain the total score for the bibliographicdatabase. Likewise, qualitative information of the evaluation is included. This provides an executive summary of the evaluation with decisive information in the decision making process about bibliographic databases in libraries

Mitochondrial physiology

As the knowledge base and importance of mitochondrial physiology to evolution, health and disease expands, the necessity for harmonizing the terminology concerning mitochondrial respiratory states and rates has become increasingly apparent. The chemiosmotic theory establishes the mechanism of energy transformation and coupling in oxidative phosphorylation. The unifying concept of the protonmotive force provides the framework for developing a consistent theoretical foundation of mitochondrial physiology and bioenergetics. We follow the latest SI guidelines and those of the International Union of Pure and Applied Chemistry (IUPAC) on terminology in physical chemistry, extended by considerations of open systems and thermodynamics of irreversible processes. The concept-driven constructive terminology incorporates the meaning of each quantity and aligns concepts and symbols with the nomenclature of classical bioenergetics. We endeavour to provide a balanced view of mitochondrial respiratory control and a critical discussion on reporting data of mitochondrial respiration in terms of metabolic flows and fluxes. Uniform standards for evaluation of respiratory states and rates will ultimately contribute to reproducibility between laboratories and thus support the development of data repositories of mitochondrial respiratory function in species, tissues, and cells. Clarity of concept and consistency of nomenclature facilitate effective transdisciplinary communication, education, and ultimately further discovery

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat

Caracterización molecular para el manejo de la colección colombiana de musaceas

The Musa germplasm bank established in Colombia has accessions tolerant to Yellow Sigatoka and is located at over 1310 meters above sea level. This germplasm has been characterized using morphological descriptors. However it is has been difficult to identify some accessions due to mutations and environmentally induced changes of some accessions. To solve this, we have used a recent molecular technique named AFLP. Two combinations of primers generating high polymorphism (EcoRI-AAG/MseI-CAT and EcoRI-AAG/MseI-CTT) were selected. UPGMA analysis grouped accessions contained genomes AA and AAA. The highest similarity index was found within the Cavendish group. Accessions containing the ABB genome showed different degrees of similarity allowing us to discriminate between Colombian accessions and those recently obtained from West Africa. Results obtained using AFLPs markers were used in conjunction with morphological descriptors, isozymes, agronomic traits and RAPDs markers in order to characterize in detail this Musa bank

La investigación en el Doctorado en Ciencias de la Educación - Rudecolombia : Educación, política educativa y bilingüismo. Tomo IV

La serie La investigación en el Doctorado en Ciencias de la Educación-RUDECOLOMBIA es un esfuerzo de la Red (Red de Universidades Estatales de Colombia) y del Doctorado en Ciencias de la Educación por ofrecer a la comunidad académica nacional e internacional, información sobre los avances en el campo de las ciencias de la educación a través de las reseñas de algunas tesis doctorales de los graduados durante los últimos 20 años. En virtud del aporte que hacen los doctores a la comprensión del fenómeno educativo desde diferentes perspectivas, fue necesario agrupar los capítulos en dos grandes temáticas: 1) Educación y Política Educativa y 2) Educación y Bilingüismo, a este último se vincula un artículo alusivo al sentido del número en la comunidad Embera-Chamí de Risaralda
