Published: July 2020

Abstract. The Ozone Monitoring Instrument (OMI) has been providing global observations of SO2 pollution since 2004. Here we introduce the new anthropogenic SO2 vertical column density (VCD) dataset in the version 2 OMI SO2 product (OMSO2 V2). As with the previous version (OMSO2 V1.3), the new dataset is generated with an algorithm based on principal component analysis of OMI radiances, but features several updates. The most important among those is the use of expanded lookup tables and model a priori profiles to estimate SO2 Jacobians for individual OMI pixels, in order to better characterize pixel-to-pixel variations in SO2 sensitivity, including over snow and ice. Additionally, new data screening and spectral fitting schemes have been implemented to improve the quality of the spectral fit. As compared with the planetary boundary layer SO2 dataset in OMSO2 V1.3, the new dataset has substantially better data quality, especially over areas that are relatively clean or affected by the south Atlantic anomaly. The updated retrievals over snow/ice yield more realistic seasonal changes in SO2 at high latitudes and offer enhanced sensitivity to sources during wintertime. An error analysis has been conducted to assess uncertainties in SO2 VCDs from both the spectral fit and Jacobian calculations. The uncertainties from spectral fitting are reflected in SO2 slant column densities (SCDs) and largely depend on the signal-to-noise ratio of the measured radiances, as implied by the generally smaller SCD uncertainties over clouds or for lower solar zenith angles. The SCD uncertainties for individual pixels are estimated to be ~ 0.15–0.3 DU (Dobson Units) between ~ 40° S and ~ 40° N and to be ~ 0.2–0.5 DU at higher latitudes. The uncertainties from the Jacobians are approximately ~ 50–100 % over polluted areas, and primarily attributed to errors in SO2 a priori profiles and cloud pressures, as well as the lack of explicit treatment for aerosols. Finally, the daily mean and median SCDs over the presumably SO2-free equatorial East Pacific have increased by only ~ 0.0035 DU and ~ 0.003 DU respectively over the entire 15-year OMI record; while the standard deviation of SCDs has grown by only ~ 0.02 DU or ~ 10 %. Such remarkable long-term stability makes the new dataset particularly suitable for detecting regional changes in SO2 pollution.
Validation of CAMS AOD using AERONET Data and Trend Analysis at Four Locations in the Indo-Gangetic Basin

Published: July 2020

Abstract. In this work we have validated Copernicus Aerosol Monitoring Service (CAMS) derived aerosol optical depth (AOD) at four locations (Kanpur, Gandhi College, Jaipur and Lahore) in the Indo-Gangetic Basin and used it to study the aerosol climatology and trend in AOD at these locations. Lahore and Kanpur are urban and industrial sites with agricultural activity in the neighbouring regions. Gandhi College is in a rural agricultural area, whereas Jaipur is a desert dust source area. Aerosol climatology at the four sites are examined with MODIS-derived NDVI and ESA-CCI derived soil moisture data. CAMS-derived AOD for black carbon, sulphate, dust, sea salt and organic matter at the four sites are studied and discussed. It is observed that sulphate AOD has the largest influence on the total aerosol climatology. Contribution from dust and sea salt aerosols is observed only during pre-monsoon and monsoon seasons, whereas non-zero AOD is observed for organic matter, black carbon and sulphate aerosols throughout the year at all sites. Comparison of CAMS AOD with AERONET AOD shows better correlation when aerosol climatology is dominated by coarse particles as compared to when it is dominated by fine particles (e.g., at Kanpur, R2pre-monsoon = 0.63 and R2winter = 0.36). Trend analysis shows largest increase in organic matter (e.g., 0.305 ± 0.021 per year at Kanpur) and least in sea salt aerosols (e.g., 0.008 ± 0.001 per year at Kanpur).
MFIT 1.0.0: Multi-Flow Inversion of Tracer breakthrough curves in fractured and karst aquifers
Authors: Bodin Jacques
Published: July 2020

Abstract. More than half of the Earth's population depends largely
or entirely on fractured or karst aquifers for their drinking water supply.
Both the characterization and modeling of these groundwater reservoirs are
therefore of worldwide concern. Artificial tracer testing is a widely used
method for the characterization of solute (including contaminant) transport
in groundwater. Tracer experiments consist of a two-step procedure: (1) introducing a conservative tracer-labeled solution into an aquifer, usually
through a sinkhole or a well, and (2) measuring the concentration
breakthrough curve (BTC) response(s) at one or several downstream monitoring
locations, usually spring(s) or pumping well(s). However, the modeling and
interpretation of tracer test responses can be a challenging task in some
cases, notably when the BTCs exhibit multiple local peaks and/or extensive
backward tailing. MFIT (Multi-Flow Inversion of Tracer
breakthrough curves) is a new open-source Windows-based computer package
for the analytical modeling of tracer BTCs. This software integrates four
transport models that are all capable of simulating single- or multiple-peak
and/or heavy-tailed BTCs. The four transport models are encapsulated in a
general multiflow modeling framework, which assumes that the spatial
heterogeneity of an aquifer can be approximated by a combination of
independent one-dimensional channels. Two of the MFIT transport models are
believed to be new, as they combine the multiflow approach and the
double-porosity concept, which is applied at the scale of the individual
channels. Another salient feature of MFIT is its compatibility and interface
with the advanced optimization tools of the PEST suite of programs. Hence,
MFIT is the first BTC fitting tool that allows for regularized inversion and
nonlinear analysis of the postcalibration uncertainty of model parameters.
Possibilistic response surfaces combining fuzzy targets and hydro-climatic uncertainty in flood vulnerability assessment
Authors: Lachaut Thibaut , Tilmant Amaury
Published: July 2020

Abstract. Several alternatives have been proposed to shift the paradigms of water management under uncertainty from predictive to decision-centric. An often mentioned tool is the stress-test response surface; mapping system performance to a large sample of future hydro-climatic conditions. Dividing this exposure space between success and failure requires clear performance targets. In practice, however, stakeholders and decision-makers may be confronted with ambiguous objectives for which there are no clearly-defined (crisp) performance thresholds. Furthermore, response surfaces can be non-deterministic, as they do not fully capture all possible sources of hydro-climatic uncertainty. The challenge is thus to combine two different types of uncertainty: the irreducible uncertainty of the response itself relative to the variables that describe change, and the fuzziness of the performance target. We propose possibilistic surfaces to assess flood vulnerability with fuzzy performance thresholds. Three approaches are tested and compared on a un-gridded sample of the exposure space: (i) an aggregation of logistic regressions based on α-cuts combines the uncertainty of the response itself and the ambiguity of the target within a single possibility measure; (ii) an alternative approximates the response with a fuzzy analytical surface; and (iii) a convex delineation expresses the largest range of failure specific to a given management rule without probabilistic assumptions. To illustrate the proposed approaches, we use the flood-prone reservoir system of the Upper Saint-François River Basin in Canada as a case study. This study shows that ambiguity can be effectively be considered when generating a response surface and suggests how further research could build a possibilistic framework for hydro-climatic uncertainty.
Modelling a tropical-like cyclone in the Mediterranean Sea under present and warmer climate

Published: July 2020

Abstract. This study focuses on a single Mediterranean hurricane (hearafter medicane), to investigate the medicane response to global warming during the middle of the 21st century and assess the contradictory effects of a warmer ocean and a warmer atmosphere on its development. Our investigation uses the state-of-the-art regional climate model WRF with the optimum combination of physical parameterizations based on a sensitivity assessment study. Results show that our model setup can reproduce a realistic cyclone track and the transition from initial disturbance to tropical-like cyclone with a deep warm core although the transition is earlier than for the observed medicane. To investigate the response of the medicane to future climate change, a pseudo global warming (PGW) approach has been used. This approach adds the projected change of atmospheric and ocean variables obtained by an ensemble of CMIP5 models to the boundary conditions for the regional climate model. A PGW simulation where all variables (PGWALL) are incremented shows that most of the medicane characteristics moderately intensify, e.g., surface wind speed, uptake of water vapour and precipitation. However the maximum depression of sea level pressure (SLP) is almost identical with that under present climate conditions. Two additional PGW simulations were undertaken; One simulation adds the projected change in sea surface and skin temperature only (PGWSST) while the second simulation adds the PGW changes to only atmospheric variables (PGWATMS) i.e. we use present time sea surface temperatures. These simulations show opposite effects on the medicane. In PGWSST, the medicane is reinforced more vigorously than PGWALL: much deeper SLP depression, stronger surface wind, and more intense evaporation and precipitation. In contrast, the medicane in PGWATMS weakens considerably (SLP, surface wind and rainfall decrease) still converts into a tropical-like cyclone with a deep warm core. This difference can be explained by an increased water vapour driven by the warmer ocean surface (favourable for cumulus convection) and the warmer and drier atmosphere in PGWATMS tends to inhibit condensation (unfavourable for cumulus convection). As a result of these counteracting effects of warmer ocean and atmosphere, the medicane is enhanced only modestly by global warming.
Optimal Precursors Identification for North Atlantic Oscillation using CESM and CNOP Method
Authors: Mu Bin , Li Jing , Yuan Shijin , Luo Xiaodan , Dai Guokun
Published: July 2020

Abstract. The North Atlantic Oscillation (NAO) is the most prominent atmospheric seesaw phenomenon in the North Hemisphere. It has a profound influence on the westerly wind strength and storm tracks in North Atlantic, which further affect the winter climate in Northern Hemisphere. Therefore, the identification for optimal precursor (OPR) of the NAO event is of research value and practical significance. In this paper, the conditional nonlinear optimal perturbation (CNOP) method, which has been widely used in research on the OPR of climatic event, is adopted to explore which kind of initial perturbation is most likely to trigger the NAO anomaly pattern in the Community Earth System Model (CESM). Since the adjoint model of CESM has yet to be developed, this kind of problem cannot be solved using traditional strategies based on gradient information provided by the adjoint model. We utilize an adjoint-free algorithm to solve CNOP in such a high dimensional numerical model, and OPRs of the NAO can be successfully identified. The results reveal that OPRs obtained by CNOP can cause the basic state to develop into typical dipole mode, and the nonlinear process plays an important role in the last stage of the prediction period. The algorithm adopted in this work can avoid falling into a local optimum and is accelerated with multiple parallel frameworks to enhance performance. The solution scheme can also be generalized to the OPR research of other climate events or other complex numerical models.
Upper Jurassic carbonate buildups in the Miechów Trough, southern Poland – insights from seismic data interpretations
Authors: Słonka Łukasz , Krzywiec Piotr
Published: July 2020

Abstract. The geometry and internal architecture of the Upper Jurassic carbonate depositional system in the epicontinental basin of central and western Europe and within the northern margin of the Tethyan shelf are hitherto only partly recognized, especially in areas with thick Cretaceous and younger cover such as the Miechów Trough. In such areas, seismic data are indispensable for the analysis of a carbonate depositional system, in particular for the identification of the carbonate buildups and the enveloping
strata. The study area is located in the central part of the Miechów
Trough that in the Late Jurassic was situated within the transition zone
between the Polish part of the central and western European epicontinental basin and the Tethys Ocean. This paper presents the results of the interpretation of 2D seismic data calibrated by deep wells that document the presence of large Upper Jurassic carbonate buildups. The lateral extent of particular structures is in the range of 400–1000 m, and their heights are in the range of 150–250 m. The interpretation of seismic data revealed that the depositional architecture of the subsurface Upper Jurassic succession in the Miechów Trough is characterized by the presence of large carbonate buildups surrounded by basinal (bedded) limestone and marly-limestone deposits. These observations are compatible with depositional characteristics of well-recognized Upper Jurassic carbonate sediments that crop out in the adjacent Kraków–Częstochowa Upland. The presented study provides new information about carbonate open-shelf sedimentation within the transition zone in the Late Jurassic, which proves the existence of a much more extensive system of organic buildups which flourished in this part of the basin. The results obtained, due to the high quality of available seismic data, also provide an excellent generic reference point for seismic studies of carbonate buildups in other basins and of different ages.
Sequential inversion of GOCE satellite gravity gradient data and terrestrial gravity data for the lithospheric density structure in the North China Craton
Authors: Tian Yu , Wang Yong
Published: July 2020

Abstract. The North China Craton (NCC) is one of the oldest cratons
in the world. Currently, the destruction mechanism and geodynamics of the
NCC remain controversial. All of the proposed views regarding the issues
involve studying the internal density structure of the NCC lithosphere.
Gravity field data are among the most important data in regard to
investigating the lithospheric density structure, and gravity gradient data
and gravity data each possess their own advantages. Given the different observational plane heights between the on-orbit GOCE
(Gravity Field and Steady-State Ocean Circulation Explorer) satellite gravity gradient and terrestrial gravity and the effects of the
initial density model on the inversion results, sequential inversion of the
gravity gradient and gravity are divided into two integrated processes. By
using the preconditioned conjugate gradient (PCG) inversion algorithm, the
density data are calculated using the preprocessed corrected gravity anomaly
data. Then, the newly obtained high-resolution density data are used as the
initial density model, which can serve as constraints for the subsequent
gravity gradient inversion. Several essential corrections are applied to the
four gravity gradient tensors (Txx, Txz, Tyy, Tzz) of the GOCE satellite, after which
the corrected gravity gradient anomalies (T′xx, T′xz, T′yy, T′zz) are used
as observations. The lithospheric density distribution result within the
depth range of 0–180 km in the NCC is obtained. This study clearly illustrates that GOCE data are helpful in understanding
the geological settings and tectonic structures in the NCC with regional
scale. The inversion results show that in the crust the eastern NCC is
affected by lithospheric thinning with obvious local features. In the
mantle, the presented obvious negative-density areas are mainly affected by
the high-heat-flux environment. In the eastern NCC, the density anomaly in
the Bohai Bay area is mostly attributed to the extension of the
Tancheng–Lujiang major fault at the eastern boundary. In the western NCC,
the crustal density anomaly distribution of the Qilian block is consistent
with the northwest–southeast strike of the surface fault belt, whereas such
an anomaly distribution experiences a clockwise rotation to a nearly
north–south direction upon entering the mantle.
Introducing a health information literacy competencies map: connecting the Association of American Medical Colleges Core Entrustable Professional Activities and Accreditation Council for Graduate Medical Education Common Program Requirements to the Association of College & Research Libraries Framework
Authors: Brennan Emily A. , Ogawa Rikke Sarah , Thormodson Kelly , Von Isenburg Megan
Published: July 2020

Background: Librarians teach evidence-based medicine (EBM) and information-seeking principles in undergraduate, graduate, and post-graduate medical education. These curricula are informed by medical education standards, medical education competencies, information literacy frameworks, and background literature on EBM and teaching. As this multidimensional body of knowledge evolves, librarians must adapt their teaching and involvement with medical education. Identifying explicit connections between the information literacy discipline and the field of medical education requires ongoing attention to multiple guideposts but offers the potential to leverage information literacy skills in the larger health sciences education sphere.Methods: A subgroup of the Association of Academic Health Sciences Libraries Competency-Based Medical Education Task Force cross-referenced medical education documents (Core Entrustable Professional Activities and 2017–2018 Liaison Committee on Medical Education Functions and Structures of a Medical School) with the Association of College & Research Libraries Framework for Information Literacy for Higher Education using nominal group technique.Results: In addition to serving as a vocabulary, the map can also be used to identify gaps between and opportunities for enhancing the scholarly expectations of undergraduate and graduate medical education standards and the building blocks of information literacy education. This article has been approved for the Medical Library Association’s Independent Reading Program.
Identifying information literacy skills and behaviors in the curricular competencies of health professions
Authors: Waltz Micah J. , Moberly Heather K. , Carrigan Esther E.
Published: July 2020

Objective: This research identified the presence of information skill and behaviors components of information literacy in curricular competencies to inform a medical sciences library’s instructional schema for five different professional programs at Texas A&M University: College of Medicine, College of Nursing, College of Veterinary Medicine and Biomedical Sciences, Irma Lerma Rangel College of Pharmacy, and School of Public Health.Methods: Curricular competency documents were collected from each program and reviewed. Coding categories were identified from the curricular competencies of professional health curricula using data-driven qualitative coding. To guide the identification and coding of competency categories, we developed a seven-category rubric from the coding categories. Three researchers used this rubric to independently code the categories of all of the included professional health curricular competencies. An additional researcher used a revised version of the rubric to identify action verbs in each competency.Results: Competencies for four of the five professional health curricula explicitly stated information skills and behaviors. Each of the five curricula included several competencies that depended on information-specific skills and behaviors. The most common verb used to describe implicit or explicit competencies was “evaluate.”Conclusions: The representation of information skills and behaviors aligns with the drive behind the Association of College & Research Libraries (ACRL) Framework for Information Literacy for Higher Education. Both underpin the importance of evidence-based medicine methodology.
Evaluating nursing faculty’s approach to information literacy instruction: a multi-institutional study

Published: July 2020

Objective: In 2018, the Association of College & Research Libraries (ACRL) Health Sciences Interest Group convened a working group to update the 2013 Information Literacy Competency Standards for Nursing to be a companion document to the 2016 Framework for Information Literacy in Higher Education. To create this companion document, the working group first needed to understand how nursing faculty approached information literacy (IL) instruction.Methods: The working group designed a survey that assessed how nursing faculty utilized IL principles in coursework and instruction. The survey consisted of nineteen mixed methods questions and was distributed to nursing faculty at eight institutions across the United States.Results: Most (79%) faculty indicated that they use a variety of methods to teach IL principles in their courses. While only 12% of faculty incorporated a version of the ACRL IL competencies in course design, they were much more likely to integrate nursing educational association standards. Faculty perceptions of the relevance of IL skills increased as the education level being taught increased.Conclusion: The integration of IL instruction into nursing education has mostly been achieved through using standards from nursing educational associations. Understanding these standards and understanding how faculty perceptions of the relevance of IL skills change with educational levels will guide the development of a companion document that librarians can use to collaborate with nurse educators to integrate IL instruction throughout nursing curriculums at course and program levels.

Las mujeres como outsiders en el periodismo deportivo: percepción de las estudiantes y personas expertas
Authors: Ramon Vegas Xavier , Gómez-Colell Eva , Figueras-Maz Mònica , Medina-Bravo Pilar
Published: July 2020

El periodismo deportivo es un ámbito caracterizado por la infrarrepresentación de la mujer deportista y la naturaleza sesgada de su tratamiento, así como por la segregación horizontal y vertical de las periodistas en las redacciones. Mediante la realización de 20 entrevistas semiestructuradas, se examina cómo las estudiantes universitarias en Cataluña perciben estas desigualdades y cómo manifiestan sus expectativas de futuro en este campo. También se ha entrevistado a 10 personas expertas en periodismo y género para ahondar en los retos a los que se enfrentan las nuevas generaciones de periodistas deportivas. Las participantes se perciben como outsiders (Hardin y Shain, 2006) y creen que su participación en el periodismo deportivo se interpretará desde los estereotipos. El artículo resalta la necesidad de ‘des-masculinizar’ y ampliar la diversidad en la formación académica, así como la importancia de romper el techo de cristal que impide a las mujeres llegar a cargos de decisión.

Published: July 2020

. La mejora de la competencia lingüística en la escuela tiene que contemplar la complejidad de los procesos que conllevan las actividades de lectura y escritura. Esta incluye considerar los factores emocionales y motivacionales implicados, tales como las actitudes y el sentimiento de competencia. Sin embargo, en nuestro país son muy escasos los estudios que se han centrado en estos aspectos, y en especial al comienzo de la escolarización. Nuestro objetivo fue identificar qué actitudes hacia la lectura y la escritura y qué sentimiento de competencia mantiene el alumnado al inicio de la Educación Primaria. Asimismo, pretendimos investigar si las actitudes se relacionan con el sentimiento de competencia en esta etapa. Los participantes fueron 725 niños y niñas de 1º y 2º curso, pertenecientes a varios centros educativos urbanos del norte de España. El instrumento empleado fue un cuestionario adaptado de la versión finlandesa del Reading Attitude Questionnaire (Merisuo-Storm y Soininen, 2012). Los resultados indican que el alumnado muestra actitudes muy positivas hacia la lectura y la escritura y que se sienten muy competentes para aprender a leer y escribir, aunque se aprecian algunas diferencias por curso. Se discuten las implicaciones educativas de estos resultados.

. Los deberes escolares, tema controvertido y de actualidad, conforman junto con las variables cognitivo-motivacionales del aprendizaje un papel relevante en el rendimiento académico. El presente estudio tiene como principal objetivo analizar la relación entre variables asociadas a los deberes escolares, las estrategias y motivación del aprendizaje, el estrés discente y el rendimiento académico en estudiantes del tercer nivel de Educación Primaria. En el estudio, de metodología cuantitativa y no experimental, participaron 519 alumnos, 279 chicos (53.8 %) y 240 chicas (46,2 %), con edades comprendidas entre los 10 y los 12 años (M = 10.74; DT = 0.66) de la comunidad autónoma de Cantabria. Los resultados indican relaciones directas entre el rendimiento académico y las estrategias de aprendizaje y motivación e inversas con el estrés percibido. Existen diferencias significativas en estrategias de aprendizaje, motivación, esfuerzo en las tareas y estrés percibido según el nivel de rendimiento académico. Este trabajo refuerza la necesidad de formar alumnos estratégicos y diseñar intervenciones psicoeducativas para la adquisición de habilidades de afrontamiento y, por otro lado, capacitar a los docentes para dar respuesta a la desmotivación y el estrés estudiantil que pueden derivar en dificultades de aprendizaje.
Conservadurismo contable, concentración de propiedad y estructuras piramidales: El caso de Chile
Authors: Medina Medina Cristian
Published: July 2020

The main objective of this document is to contribute through empirical evidence, to the literature that deals with the concept of accounting conservatism. Specifically, it analyzes how conservative the Chilean financial market is, and analyze the effects that the ownership structure of the firm has on the level of accounting conservatism. The sample used consists of an unbalanced panel with financial information of 119 companies listed on the Santiago de Chile stock exchange for the 2007-2011 study period, obtained from the Thomson One database (Thomson Reuters) and with data collection of the Superintendency of Securities and Insurance (SVS). The results indicate that effectively there is evidence in the Chilean market, that the concentration of property negatively affects the level of accounting conservatism. However, it is not possible to determine that in companies with pyramid-owned structures the level of accounting conservatism decreases.
Sponsorship sales is not only a sport, but an institutional business as well: evidence from two professional football clubs in Latin-America.
Authors: Navarro Picado José Francisco
Published: July 2020

The purpose of this paper is to identify the impact of institutionalization, legitimacy, learning behaviors, and other organizational characteristics on the efforts made by sport clubs signing sponsorship contracts. An exploratory comparison of two professional football clubs, playing in the First Division, of Costa Rica and Chile was performed. Using a narrative methodology, the Costa Rican team was analyzed through observation during a two-year collaboration period, and the Chilean team was analyzed through in-depth interviews and an analysis of the historical literature. The analysis revealed that organizational behaviors impact the clubs’ amount of sponsorship contracts and multi-season contracts. It also revealed that institutionalization and legitimacy work as a first latter in the relationship, and that by themselves it should be considered a marketing tool. Additionally, it was observed that both learning behaviors and resource seeking strategies contribute to successfully sign sponsorship contracts, but a baseline level of legitimacy and institutionalization should exist.

Drawing on Institutional Theory, Ecology, and Organizational Learning a clear role model was evidenced within the ecosystem of two professional football clubs, each on

a different Latin American country. These behaviors, which up to our knowledge has never being analyzed before, yielded and sustained legitimacy, while showing a direct

effect on sponsorship single-season and multi-season contracts.

Introducción: Generar evidencia sobre los efectos de la posición social en la adhe¬rencia terapéutica en personas con hipertensión arterial (HTA) en Colombia.

Materiales y Métodos: Se realizó un estudio transversal, a partir de mediciones cuan¬titativas del Programa de Determinantes Sociales e Inequidades en el Control de la HTA en Colombia. Se desarrollaron análisis descriptivos e inferenciales (regresión logística) para modelar las asociaciones.

Resultados: Se evidenció una alta proporción de adherencia, siendo mayor para cumplimiento farmacológico y las citas (>50%). Las personas con menor educación e ingresos tienen menor posibilidad de adherirse al tratamiento farmacológico; mien¬tras que quienes tienen mejor posición socioeconómica tienen menor posibilidad de adherirse a las citas y a las conductas saludables. Los afrocolombianos tienen menor posibilidad de adherirse al tratamiento farmacológico, a las citas y a la actividad física.

Discusión: Existe una brecha en el logro de la adherencia a tratamiento de HTA en Colombia, debido a condiciones socioeconómicas y étnica/raciales.

La obesidad es considerada por la Organización Mundial de la Salud como un gra¬ve problema de salud pública. En Chile los datos de la Encuesta Nacional de Salud 2016-2017 muestran que 7 de cada 10 chilenos presentan sobrepeso u obesidad y, según datos del Ministerio de Educación, en los niños que ingresan a la enseñanza básica, la prevalencia de obesidad no ha logrado bajar del 25%. En los últimos años ha habido un reconocimiento mundial sobre la influencia que tienen los Ambien-tes Alimentarios en el comportamiento de las personas y en el estado nutricional de las poblaciones. Recientemente en el país se han identificado los Ambientes Ali¬mentarios predominantes y sus factores condicionantes, lo que ha culminado con la elaboración de la Política Nacional de Alimentación y Nutrición y los lineamientos que permiten avanzar en diferentes estrategias para modificar dichos ambientes. En Chile se han implementado medidas individuales y estructurales que han tenido gran relevancia tanto a nivel nacional como internacional, aunque está pendiente la ela-boración de instrumentos que midan de manera objetiva y confiable los Ambientes Alimentarios

Para ello, se realiza una revisión bibliográfica de diversos artículos científicos que proporcionan información sobre los modelos de estilos de aprendizaje, los instrumentos de medición que existen y la utilidad del estudio de los estilos de aprendizaje, relevante para comprender el tema de estudio. En la revisión realizada se encontró que los modelos más conocidos y utilizados en diversas investigaciones son: el modelo de Felder y Silverman, el modelo de Kolb y el modelo de Honey y Mumford. Por otra parte, uno de los instrumentos más utilizados en las universidades de América Latina y España es el Cuestionario de Honey-Alonso de Estilos de Aprendizaje (CHAEA) y se utiliza como diagnóstico para conocer el estilo de aprendizaje de los estudiantes lo que permite adecuar o diseñar las estrategias de enseñanza-aprendizaje en función de los estilos de aprendizaje.

Authors: Medina López Moisés , Romero Díaz Tonys
Published: July 2020

El abandono escolar afecta a todas las universidades en el mundo entero. En esta investigación se explican las características que poseen los estudiantes que abandonan las carreras de la universidad URACCAN-Nueva Guinea, corte 2013-2017. Además, se propone un modelo de retención estudiantil para esta universidad. Esta investigación se realizó con dos muestras. El primer objetivo se desarrolló con todos los 347 estudiantes que se matricularon en el primer año de su carrera en el 2013. El segundo y tercer objetivo, se trabajan con 137 estudiantes retirados. Se usó el método mixto y un alcance correlacional, fenomenológico y por su ubicación temporal es un estudio transversal. En este estudio se encontró que las variables que tienen influencia estadística sobre el abandono estudiantil son la asignatura que el estudiante escoge, el número de asignaturas reprobadas y el promedio obtenido en URACCAN. A su vez las variables estudiadas y que no influyen estadísticamente en el retiro son: género, estado civil, zona de residencia, tipo de escuela en que estudió, modalidad, edad del estudiante, rendimiento académico de cuarto y quinto año y trabajo. Por último, se realizó un plan de retención estudiantil para la universidad URACCAN.
Blas de Otero: del existencialismo a la poesía social
Authors: Sarango Cristhian
Published: July 2020

Este trabajo ha analizado la evolución de la poética de Blas de Otero. Para ello fue considerado que, en su poética opera una dualidad altisonante: desde uno de los imaginarios es uno de los poetas más leídos de la historia reciente de España y, sin embargo, el otrora de la crítica lo desdeña por la politización de su obra; en su polivalencia la poesía oteriana es tensión existencial, en su primera etapa, y una evidente preocupación social; en la segunda. Blas de Otero es un poeta de conceptos, en particular de contenido social, porque su poesía temprana revela el desgarramiento humano frente al sufrimiento y la angustia existencial del hombre de posguerra. Su evolución como poeta parte de sus inquietudes religiosas y de fe, pasando por el existencialismo, hasta llegar al contenido social. Los textos analizados en este trabajo son una muestra de esa evolución temática en etapas distintas de la producción literaria del autor: “Estos sonetos míos”, Ángel fieramente humano (1950) y “Fidelidad”, Pido la paz y la palabra (1955).

Published: July 2020

Current study aimed at exploring Creative self-efficacy and its' relationship to intellectual stress among gifted students at jubilee school. Study sample consists of (N=100) of secondary intermediate stage students, Al-Zoubi scale (2014) to measure intellectual stress and Abbott scale (2010) to measure creative self-efficacy were used by researchers. Results reported that creative self-efficacy with its' two dimensions: creative thinking and creative performance among gifted students was in high degree, while intellectual stress level was in moderate degree. Study results also showed that no statistical differences attributed to class and sex variables, study revealed an inverse correlation between study dimensions, whenever efficacy increased in creative thinking and creative performance, intellectual stress is decreasing. Researchers recommend the importance of training gifted students' teachers on developing creative performance and thinking among gifted students, and provision therapeutic and counseling programs to decrease any psychological or intellectual stresses by holding workshops that expand enrichment and knowledge sides among teachers and gifted students.
Remeasuring Sectoral Herding in the Financial Markets
Authors: Elshqirat Mohammad K.
Published: July 2020

Herding behavior was concluded to exist in some sectors and under some market conditions in the Jordanian stock market when measured using the cross-sectional absolute deviation. The purpose of this study was to retest the existence of the sectoral herding using the cross-sectional dispersion of betas and compare the results with those reached using the measure of the cross-sectional absolute deviation. Behavioral finance theory represents the main base on which this study was built. In this study, the researcher tried to answer questions related to whether herding behavior exists in the Jordanian market and its sectors if measured using cross-sectional dispersion of betas and whether results will be different from those reached using other measures. In this quantitative study, data from Amman stock exchange were used and the period covered was from 2000 to 2018. These data were used to calculate the cross-sectional dispersion of betas which was tested using t-test, Kruskal–Wallis test, Mann-Whitney U test, and Wilcoxon Signed-Rank test. Results indicated that herding behavior existed in market and in each sector at the same level which was not affected by the financial crisis. Furthermore, the study revealed that herding level was the same when the market (sector) was rising and when it was falling and this similarity has not been changed by the occurrence of the global financial crisis. Finally, results indicated that herding was at its lowest level in the entire market and in the industrial sector during the time of financial crisis. These results are different from those of the study conducted in Jordan using cross-sectional absolute deviation which implies that using different herding measures yields different results.
The partial inverse nodal problem for differential pencils on a finite interval
Authors: Wang Y. P. , Hu Yiteng , Shieh Chung-Tsun
Published: July 2020

In this paper, the partial inverse nodal problem for differential pencils with real-valued coefficients on a finite interval \([0,1]\) was studied. The authors showed that the coefficients \((q_{0}(x),q_{1}(x),h,H_0)\) of the differential pencil \(L_0\) can be uniquely determined by partial nodal data on the right(or, left) arbitrary subinterval \([a,b]\) of \([0,1].\) Finally, an example was given to verify the validity of the reconstruction algorithm for this inverse nodal problem.
CONCEPT OF VIRTUAL INTERACTIVE CENTRE PERFECTING PROFESSIONAL SKILLS OF BORDER GUARD OFFICERS
Authors: Burnat Katarzyna
Published: July 2020

The paper presents a project aimed to develop, start, and test a modern didactic centre for the Border Guard. Implementation of an innovative interactive 3D multimedia cave for perfecting the procedures of using the weapons and direct enforcement means, and checking the persons, vehicles and goods, shall improve the qualifications of the border guard officers in conditions similar to realistic ones. The virtual interactive centre for perfecting professional skills is aimed to train the officers on a wide range of situations starting from operational planning, depending on the encountered and changeable situation including also terroristic incidents, and throughout the decision making at operational conditions relevant to the Border Guard tasks, the use of shooting skills and means of direct enforcement, and ending on providing the first aid and teaching the preparation of reports. It is important that a decision made by a trainee at a specific moment of scenario could trigger a following stage of an evolving situation or its termination. It is assumed that the course of an exercise may be recorded and replayed to make a detailed analysis of actions undertaken by trainees, and to discuss faults, and to find out correct solutions for critical situations.
Corona-Politik 2020 – ein schmaler Grat zwischen kluger Einschränkung und überzogener Panik
Authors: Frommel Monika
Published: July 2020

Der Beitrag beschreibt die aktuellen Maßnahmen der „Corona-Politik“ unter rechtlichen, rechtspolitischen und gesellschaftlichen Gesichtspunkten. Kritisiert wird die irreführende Verwendung des statistischen Zahlenmaterials durch Politik und Medien. Es ist keineswegs ausgemacht, ob man mit dem „Schwedischen Modell“, das mehr auf Einsicht und Vernunft der Bürger und weniger auf Verbote setzt, nicht ähnliche Resultate auch in Deutschland hätte erzielen können. Die weit verbreitete Kritik am deutschen Föderalismus und seinen Auswirkungen auf die Corona-Politik ist dagegen zurückzuweisen: Der Föderalismus ist besser als sein Ruf.
