Abstract Objectives The present study aimed to evaluate the measurement invariance of a general measure of the perception of governmental responses to COVID-|19 (COVID-SCORE-10) in the general population of 13 Latin American countries. Methods A total of 5780 individuals from 13 Latin American and Caribbean countries selected by non-probabilistic snowball sampling participated. A confirmatory factor analysis was performed and the alignment method was used to evaluate invariance. Additionally, a graded response model was used for the assessment of item characteristics. Results The results indicate that there is approximate measurement invariance of the COVID-SCORE-10 among the participating countries. Furthermore, IRT results suggest that the COVID-SCORE-10 measures with good psychometric ability a broad spectrum of the construct assessed, especially around average levels. Comparison of COVID-SCORE-10 scores indicated that participants from Cuba, Uruguay and El Salvador had the most positive perceptions of government actions to address the pandemic. Thus, the underlying construct of perception of government actions was equivalent in all countries. Conclusion The results show the importance of initially establishing the fundamental measurement properties and MI before inferring the cross-cultural universality of the construct to be measured.

Introduction. The learning achieved by students during clinical practice depends on multiple factors, such as the disciplinary and generic competencies of the clinical teacher who supervises these experiences. Objective. To recognize the competencies that a clinical teacher, who supervises practices in in-hospital care centers must have, from the perspective of nursing students of the Austral University of Chile during the year 2019. Subjects and methods. Qualitative research, using Natural Semantic Networks Technique. Intentional sample of cases by criteria made by 20 nursing students in the third and fourth years (2019), who individually and with prior informed consent were asked to write 10 words in five minutes (verbs, adverbs, adjectives, nouns). These words related to the stimulus question: what are the competencies that the clinical teacher must have to promote learning in nursing students? subsequently prioritizing them from one to ten, with one corresponding to the highest value. The analysis is carried out by progressive reduction of the information according to the aforementioned technique. Reliability was guaranteed by rigorous criteria, endorsed by the Scientific Ethics Committee, Valdivia Health Service. Results. The students mostly identified generic competences as favoring learning, highlighting ‘feedback' (100%), ‘empathic' (93.9%), ‘welcoming' (56.1%), respectful (57.7%), ‘Effective communication' (41.2%), ‘teacher training' (40.3%). Conclusions. the students value the interpersonal skills and pedagogical-clinical training of the in-hospital clinical practice teacher, they consider that the clinical teacher's competencies are a fundamental aspect that directly influences learning.

Introducción. Los aprendizajes logrados por los estudiantes durante la práctica clínica dependen de múltiples factores, entre ellos, las competencias disciplinares y genéricas que tenga el docente clínico que supervisa dichas experiencias. El objetivo del estudio fue reconocer las competencias que debe tener un docente clínico que supervisa prácticas en centros asistenciales intrahospitalarios desde la perspectiva de estudiantes de enfermería de la Universidad Austral de Chile durante 2019. Sujetos y métodos. Es una investigación cualitativa mediante la técnica de redes semánticas naturales. Es una muestra intencionada, de casos por criterios, constituida por 20 estudiantes de enfermería de tercer y cuarto año (2019), a quienes de forma individual, previo consentimiento informado, se les solicitó que escribieran en cinco minutos 10 palabras (verbos, adverbios, adjetivos y sustantivos) relacionadas con la pregunta estímulo, ¿cuáles son las competencias que debe tener el docente clínico para favorecer el aprendizaje en estudiantes de enfermería?, y que las priorizaran posteriormente de 1 a 10, correspondiendo el 1 a la de mayor valor. El análisis se realizó por reducción progresiva de la información de acuerdo con la técnica mencionada. La confiabilidad se garantizó mediante criterios de rigor, avalada por el Comité Ético Científico del Servicio de Salud Valdivia. Resultados. El estudiantado identificó mayoritariamente competencias genéricas como favorecedoras del aprendizaje, y destacaron ‘retroalimentación' (100%), ‘empático' (93,9%), ‘acogedor' (56,1%), ‘respetuoso' (57,7%), ‘comunicación efectiva' (41,2%) y ‘formación docente' (40,3%). Conclusiones. Los estudiantes valoran las habilidades interpersonales y la formación pedagógica-clínica del docente de práctica clínica intrahospitalaria, y estiman que las competencias del docente clínico son un aspecto fundamental que influye directamente en sus aprendizajes.

Introduction: Due to its efficacy in the treatment of morbid obesity, roux-en-y gastric bypass (RYGB) continues to be a frequently performed intervention. However, a small group of patients may develop nutritional and metabolic complications that cannot be controlled with optimal medical treatment. In these cases, it may be necessary to reestablish the continuity of the gastrointestinal tract by reversing the RYGB (R-RYGB). Aim: To present the indications and results obtained in a series of patients who underwent to R-RYGB. Materials and Method: Identification and retrospective evaluation of all patients who underwent consecutive R-RYGB in our institution. Demographic and anthropometric characteristics of the original surgery and at the time of the reversal were recorded. Complications were classified according to Clavien-Dindo classification. Results: Seven patients were identified in whom an R-RYGB was performed. In 2 cases the reversal was due to short bowel syndrome, in 3 cases due to severe hypoglycemia refractory to medical treatment and in 2 cases due to chronic diarrhea. The median age at the time of the reversal was 55 years. The median time from primary surgery to reversal was 77 months. The median hospital stay was 6 days. There were no Clavien-Dindo complications ≥ III. The R-RYGB was able to reverse nutritional and metabolic complications in all cases. Conclusion: Restoring the continuity of the gastrointestinal tract allows control of nutritional and metabolic complications.

Resumen Introducción: Debido a su eficacia en el tratamiento de la obesidad mórbida, el bypass gástrico (BPG) sigue siendo una intervención realizada frecuentemente. Sin embargo, un grupo reducido de pacientes puede desarrollar complicaciones nutricionales y metabólicas que no logran controlarse con un tratamiento médico óptimo. En estos casos, puede ser necesario reestablecer la continuidad del tracto gastrointestinal por medio de la reversión del BPG (R-BPG). Objetivo: Presentar las indicaciones y resultados obtenidos en una serie de pacientes sometidos a una R-BPG. Materiales y Método: Identificación y evaluación retrospectiva de todos los pacientes sometidos a una R-BPG en nuestra institución de manera consecutiva. Se registraron las características demográficas y antropométricas de la cirugía original y al momento de la reversión. Las complicaciones se registraron de acuerdo con la clasificación de Clavien-Dindo. Resultados: Se identificaron 7 pacientes en los cuales se realizó una R-BPG. En 2 casos la reversión fue por síndrome de intestino corto, en 3 casos por hipoglicemias severas refractarias a manejo médico y en 2 casos por diarrea crónica. La mediana de edad al momento de la reversión fue de 55 años. La mediana de tiempo desde la cirugía original hasta el momento de la reversión fue de 77 meses. La mediana de estadía hospitalaria fue de 6 días. No hubo complicaciones Clavien-Dindo ≥ III. La R-BPG logró revertir en todos los casos las complicaciones nutricionales y metabólicas. Conclusión: La restauración de la continuidad del tracto gastrointestinal permite el control de las complicaciones nutricionales y metabólicas.

Abstract Learning disposition strategies (setting goals, managing time, and organizing resources) are key to self-regulated learning and student performance and so they should be measured as accurately as possible. However, instruments to measure learning strategies are too general to evaluate dispositional strategies. The aim of this study was to design and analyze the psychometric properties of a learning disposition strategy instrument for university students, which was administered to a convenience sample of 630 Chilean university students. An explanatory and confirmatory factor analysis was carried out. The full scale and its four subscales showed adequate internal consistency (α > 0.70), a latent structure that fit the data and weak but statistically significant correlations with student-reported grades. It is concluded that the instrument is reliable and valid for use with higher education students.

Resumen Las estrategias de disposición al estudio (establecer objetivos, gestionar el tiempo y organizar recursos) son claves para el aprendizaje autorregulado y el desempeño de los estudiantes, por lo que su medición debe ser lo más precisa posible. Sin embargo, los instrumentos para medir estrategias de aprendizaje son muy generales para evaluar estas estrategias disposicionales. Este estudio tuvo como objetivo diseñar y analizar las propiedades psicométricas del instrumento de estrategias de disposición al estudio en estudiantes universitarios, el cual fue aplicado a una muestra por conveniencia de 630 estudiantes universitarios chilenos. Se realizó análisis factorial exploratorio y confirmatorio. La escala total y sus 4 subescalas mostraron consistencia interna adecuada (α > 0.70), estructura latente ajustada a los datos y correlaciones débiles, aunque estadísticamente significativas, con las calificaciones reportadas por los alumnos. Se concluye que el instrumento es confiable y válido para su aplicación en estudiantes de educación superior.

Background Team-Based Learning methodology (TBL) is used in medicine teaching in different clinical and basic fields, but seldom in statistics courses. Aim To compare the performance of students taught using TBL with those receiving the traditional lecture modality. Materials and Methods The grades and percentage of correct answers obtained in exams written during the statistics course of students that were taught without TBL (years 2009-2011) or using this methodology (years 2013-2016) were compared. Z Test for one mean (Milestone 1) and Student’s t test for two independent means assuming equal variances/unequal variances (Milestone 2) were evaluated. The mean and minimum grades and the percentage of grades below the flunking threshold were also evaluated. Students’ assessment of the methodology was also recorded. Results The percentage of correct answers was 94.2% and 94% among students taught with and without TBL methodology, respectively (Milestone 1), achieving a similar performance independent of the teaching strategy. The global percentage of correct answers of Milestone 2 increased from 75.3% to 89.5% (P < 0.001) among students using TBL. In 75.0% of questions, the percentage of correct answers increased with TBL. Likewise, there was an increase in mean grades increased from 5.4 to 6.2 (P < 0.05) and mean minimum grades from 2.8 to 3.7 (P = 0.05). The proportion of grades below the flunking threshold decreased from 9.9% to 4.4% (P = 0.054). Almost all students evaluated TBL methodology positively. Conclusions Students taught using TBL methodology performed better in the statistics course evaluation than students attending standard lectures in statistical analysis of greater complexity. TBL was well evaluated.

The aim of this study is to analyze the relationship between (1) willingness to study strategies, (2) causal attributions (to effort, ability and external causes) and (3) student´s perception of self-efficacy about their ability to self-regulate their processes of willingness to study. Method: An instrument built by the researchers called Willingness to the Study Self-Regulation Questionnaire was applied to a non-probabilistic convenience sample of 695 Chilean university students from 5 universities of the Province of Concepción. Outcomes: Strong correlations were found between self efficacy for the willingness to study self-regulation and the willingness to study strategies (r=0.54 to r =0.55). the willingness to study strategies had positive and moderate correlations (r=0.38 to r=0.42) with causal attributions for success to effort, weak correlations (r=0.15 to r=0.28) with causal attributions for success to ability and to external factors, and negative weak to moderate correlations (r=-0.19 to r =-0.38) with causal attributions for failure to effort, ability, and external factors. Conclusions: Students with high levels of willingness to study strategies show positive beliefs about their own ability to self-regulate their processes of willingness to study, they make causal attributions for their success mainly to effort, and they attribute their academic failure less and less to ability and external factors.

El objetivo de este estudio es: analizar la relación entre (1) Las estrategias disposición al estudio, (2) atribuciones causales (al esfuerzo, capacidad y causas externas) y (3) la percepción de autoeficacia que tienen los estudiantes sobre su capacidad de autorregular sus procesos de disposición al estudio. Método: Se aplicó un instrumento construido por los investigadores denominado Cuestionario de Autorregulación de la Disposición al Estudio a una muestra no probabilística por conveniencia de 695 estudiantes universitarios chilenos de 5 universidades de la provincia de Concepción. Resultados: Se encontraron correlaciones fuertes entre la autoeficacia para la autorregulación de la disposición al estudio y las estrategias de disposición al estudio (r=0.54 a r=0.55). Las estrategias de disposición al estudio presentan correlaciones positivas y moderadas (r=0.38 a r= 0.42) con las atribuciones causales de éxito al esfuerzo, débiles (r=0.15 a r= 0.28) con las atribuciones causales de éxito a la habilidad como a las atribuciones causales de éxito a causas externas, y correlaciones negativas, de débiles a moderadas (r=-0.19 a r= -0.38), con las atribuciones causales de fracaso al esfuerzo, a la habilidad y a causas externas. Conclusiones: Los estudiantes con altos niveles de estrategias de disposición al estudio presentan creencias positivas acerca de la propia capacidad para autorregular sus procesos de disposición al estudio, realizan atribuciones causales de sus éxitos principalmente al esfuerzo y disminuyen las explicaciones de fracasos académicos a su esfuerzo, su capacidad y a causas externas.

Abstract: En | Text: En | PDF: En

We investigate, by means of a field-theory analysis combined with the density-matrix renor-malization group (DMRG) method, a theoretical model for a strongly correlated quantum system in one dimension realizing a topologically-ordered Haldane phase ground state. The model consists of a spin-1/2 Heisenberg chain coupled to a tight-binding chain via two competing Kondo exchange couplings of different type: a s-wave Kondo coupling (J Ks ), and a less common p-wave (J Kp ) Kondo coupling. While the first coupling is the standard Kondo interaction studied in many condensed-matter systems, the latter has been recently introduced by Alexandrov and Coleman Phys. Rev. B 90, 115147 (2014) as a possible mechanism leading to a topological Kondo-insulating ground state in one di-mension. As a result of this competition, a topological quantum phase transition (TQPT) occurs in the system for a critical value of the ratio J Ks /J Kp , separating a (Haldane-type) topological phase from a topologically trivial ground state where the system can be essentially described as a product of local singlets. We study and characterize the TQPT by means of the magnetization profile, the entanglement entropy and the full entanglement spectrum of the ground state. Our results might be relevant to understand how topologically-ordered phases of fermions emerge in strongly interacting quantum systems.

Background: It is not known whether leaded glass goggles with 0.25 mm Pb equivalency, used in interventional cardiology procedures, attenuate radiation below the levels established by the latest recommendation of the International Commission on Radiological Protection (ICRP). Aim: To assess ifthe degree of attenuation of the secondary ionizing radiation achieved by the use of 0.25 mm Pb leaded glass goggles, in occupationally exposed workers in interventional cardiology procedures, meets the latest ICRP recommendations. Material and Methods: A prospective investigation was carried out to compare the eye exposure to secondary ionizing radiation received by occupationally exposed personnel in a 9 months period. A set of two thermo luminescent dosimeters was arranged in the front and back of leaded glass goggles in a cohort ofseven members of an interventional cardiology service, exposed to 1057 consecutive procedures. Results: The monthly dose equivalent measurement performed in front ofthe goggles ranged between 1.1 and 6.5 mSv, for paramedics and interventional cardiologists. The radiation measured in the back of the glass varied between 0.66 and 2.75 mSv, respectively. The degree of attenuation of the dose at eye level ranged from 40% to 57.7%, respectively. The projected annual exposure would reach 33 mSvfor the interventional cardiologist. Conclusions: With a similar load ofwork and wearing 0.25 mm Pb equivalent glass goggles, interventional cardiologists will exceed the crystalline equivalent dose limit recommended by the ICRP (20 mSv/year averaged over the past 5 years).

Spatial discontinuations, as those found in cities and buildings, are everyday events. But, how do we encode and classify such misalignments? This is the topic of this paper. Twenty participants were asked to classify a total of 51 icons showing an upward-moving line being misaligned to the right, left and straight down. The results show that subjects were very sensitive to slight discontinuations occurring to vertical lines and that there was not exact symmetry between the left and right axis, meaning that the pieces slightly misaligned to the left were encoded differently than those misaligned to the right

This paper shows an alternative to the classic electro winning copper process using a cell based on reactive electrodialysis, which consists of two compartments separated by an anionic membrane, one of which contains the copper sulphate catholyte, where the cathode is located, and the other compartment contains the ferrous sulfate anolyte, where the anode is located. In this type of cell the anodic reaction is the oxidation of iron (Fe2+ to Fe3+), which consumes less energy than the classic water oxidation. Moreover, this new anodic reaction does not produce acid mist.

OBJECTIVE: In this work, a questionnaire was designed and perceptions of motivation and demotivation of middle managers in three hospitals in the Region del Maule, Chile were measured. MATERIAL AND METHODS: The fieldwork was carried out between September and October, 2006. A questionnaire that included 57 statements to measure attitude was administered and qualified according to a five-point Likert-type scale. The population studied included l25 professionals that supervise roughly 3 800 employees. RESULTS: Ten variables were identified, 5 motivational and 5 demotivational. Notable among the motivational variables are vocation and service-oriented spirit; among the demotivational variables are lack of recognition and commitment. DISCUSSION: It is affirmed that both motivational variables as well as demotivational variables are essentially qualitative and that economic and salary variables are less relevant and less hierarchical.

OBJETIVO: En este trabajo se diseña un cuestionario y se cuantifican las percepciones de motivación-desmotivación de los jefes intermedios de tres hospitales de la Región del Maule, Chile. MATERIAL Y MÉTODOS: El trabajo de campo se realizó entre septiembre y octubre de 2006, se aplicó un cuestionario con 57 afirmaciones de medición de actitudes que se calificó de acuerdo con una escala tipo Likert de cinco puntos. La población objeto de la investigación fue de 125 profesionales bajo cuya supervisión se encuentran alrededor de 3 800 funcionarios. RESULTADOS: Se identificaron 10 variables, cinco motivacionales y cinco desmotivacionales. Entre las primeras destacan vocación y espíritu de servicio; entre las segundas falta de reconocimiento y falta de compromiso. DISCUSIÓN: Se confirma que tanto las variables motivacionales como las desmotivacionales son esencialmente cualitativas y que las variables económica y de sueldos son menos relevantes y de inferior jerarquía.
