The article deals with constructing and implementing mathematical models of non-isothermal moisture transfer during drying of anisotropic capillary-porous materials, in particular wood, taking into account the movement of the evaporation zone for non-steady drying schedules, as well as to the development of effective analytical and numerical methods for their implementation. An analytical-numerical method for the determination of non-isothermal moisture transfer under non-steady schedules of the drying process has been developed, taking into account the dynamics of the phase transition boundary change. Calculation relationships are established for determining the phase transition temperature taking into account transport gradients and time for which the relative saturation reaches the boundaries of the phase transition.
La axiología como guía para una definición del objeto de la disciplina contable en el siglo XXI
Authors: Hauque Sergio Miguel , Di Russo Leila
Published: December 2021

En el trabajo se señala la importancia de la jerarquía de los valores humanos involucrados en los marcos conceptuales de los sistemas contables para la construcción de informes sociales. Se sostiene aquí que una de las disciplinas que más ha trabajado para la valoración de acciones y hechos reales conforme a patrones de sistemas de valores humanos es la contabilidad. Allí se ha profundizado aún más que en otras disciplinas propiamente axiológicas el estudio y medición de una de las tipologías de los valores humanos: la de los útiles o económicos.

La visión axiológica se basa en la no indiferencia ante las acciones humanas. Es el hombre el que valora y evalúa, sobre la base de una escala de valores, emitiendo juicios en este sentido. El valor económico es uno más dentro de esa complicada jerarquía que permite evaluar acciones. Dado que este valor no encabeza esa escala, los informes sobre la responsabilidad social integral de las organizaciones lo incluyen, pero no le brindan el rol que posee en los tradicionales informes contables privados.

Se plantean tres posibles marcos de análisis integrados desde la axiología.

La evaluación unidimensional de las acciones de las organizaciones sobre la única base del valor económico para sí misma.

Una evaluación en la que también interesa conocer el valor económico que la organización permite crear para el resto de la comunidad actual y futura.

Una evaluación más completa teniendo en mira la totalidad de los valores humanos, económicos y no económicos.

El trabajo concluye en que nunca es sencillo proveer información para elegir en estos contextos de hechos inciertos, valores en discusión, altos riesgos y decisiones urgentes, pero debemos hacerlo en función de la compatibilidad entre la jerarquía de valores humanos y las misiones de las organizaciones proveedoras de la información.

Published: December 2021

En los últimos años ha aumentado la presencia de la tecnología en las aulas de nuestros centros educativos y la etapa de Educación Infantil no ha quedado al margen de este acontecimiento. Esta realidad despertó interés para desarrollar el proyecto de I+D+i “Los materiales didácticos digitales en la Educación Infantil. Análisis y propuestas para su uso en la escuela y el hogar. Infanci@ Digit@l” en el que se enmarca este artículo. El objetivo del mismo es realizar una comparativa entre cinco plataformas de materiales didácticos digitales de diversa naturaleza (institucionales, editoriales y de acceso libre) de la comunidad autónoma gallega. Para ello se aplica una guía de evaluación que se centra en las características tecnológicas, pedagógicas y socio-comunicacionales de dichas plataformas. Del mismo modo, se tienen en cuenta si estos recursos atienden a las características, necesidades e intereses del alumnado de la etapa educativa a la que van destinados. A través de este análisis llegamos a la conclusión de que las plataformas se están adaptando a la realidad de nuestra sociedad, pero de manera muy paulatina y superficial.

Published: December 2021

Teniendo en cuenta el carácter innovador que, a priori, implica la incorporación de materiales didácticos digitales al proceso de enseñanza-aprendizaje, y siendo la educación infantil una de las etapas del sistema educativo reglado que debiera destacar también por su carácter innovador, entendemos que es de gran interés conocer el modelo pedagógico que subyace a estos materiales. Por lo tanto, el objetivo de este artículo es analizar el modelo pedagógico de materiales para el segundo ciclo de educación infantil publicados por editoriales gallegas, como parte de la oferta de recursos educativos digitales a disposición del profesorado en esta comunidad. Concretamente, el análisis se centra en el tipo de actividades y recursos complementarios, así como el rol del profesorado y del alumnado de una muestra de ocho materiales de cuatro editoriales diferentes. Para el análisis de los datos se tiene en cuenta el grado de coherencia de lo hallado con lo que establece el currículo oficial para esta comunidad autónoma. Los resultados sugieren que si bien el carácter digital del material no supone cambios significativos en los modelos pedagógicos y no se aprovechan las potencialidades que brindan las tecnologías, el carácter abierto y flexible de esta etapa posibilita la adaptación de los mismos.

Published: December 2021

OBJECTIVE

To evaluate the feasibility of CT lymphangiography via intrametatarsal pad injection in cats with chylothorax.

ANIMALS

7 client-owned cats.

PROCEDURES

This was a multicenter, retrospective, descriptive study. Medical records and imaging data from 4 veterinary hospitals were reviewed to identify cats with chylothorax that had undergone intrametatarsal pad injection via CT lymphangiography. In total, 7 client-owned cats were included in the study. Signalment, history, image findings, and follow-up data were recorded. Descriptive statistics were used to analyze the success rate of thoracic duct (TD) enhancement and describe relevant clinical findings.

RESULTS

Enhancement of TDs was successful in 6 of the 7 cats within 5 to 15 minutes after initiating intrametatarsal pad injection under general anesthesia. Successful migration of contrast medium into the lymphatic vessels cranial to the popliteal lymph nodes was observed in all cats within 5 minutes after injection. The recommended dose of contrast medium to achieve TD enhancement was 1 mL/kg (0.5 mL/kg/pad; concentration, 350 mg of iodine/kg). Only 1 cat had mild swelling of the paws after the procedure, and it recovered quickly without pain medication; no cats experienced lameness. Similar to dogs and unlike in previously published reports, 72% of TD branches were located in the right hemithorax.

CLINICAL RELEVANCE

CT lymphangiography via intrametatarsal pad injection is a feasible and safe procedure for cats with chylothorax. This technique provides detailed information regarding the unique TD anatomy and cisterna chyli location. It also contributes to surgical planning.

Funciones Ejecutivas y Rendimiento Académico en Educación Primaria de la Costa Colombiana
Authors: Porto Torres Maria F. , Puerta-Morales Laura , Gelves-Ospina Melissa , Urrego-Betancourt Yaneth
Published: December 2021

Introducción.  Las Funciones Ejecutivas (FE) son un conjunto de funciones supramodales que favorecen a las habilidades cognitivas, emocionales y sociales. En la primera infancia las FE influyen en el rendimiento de las habiliadades académicas. La presente investigación determinó la relación entre las funciones ejecutivas y el rendimiento académico en un contexto educativo.
Método.  Se realizó un estudio correlacional donde participaron 195 estudiantes entre 6 y 12 años de edad, seleccionados al azar de los grados de básica primaria (de 1° a 5°). Las funciones ejecutivas medidas fueron: fluidez verbal (fonológica y semántica), atención selectiva, flexibilidad cognitiva, planificación e inhibición; para lo cual, se empleó la Evaluación Neuropsicológica de las funciones ejecutivas en niños (ENFEN) y el rendimiento académico se evaluó a partir del promedio académico acumulativo en el año.
Resultados. De acuerdo con el análisis de correlación de Spearman, los resultados arrojados señalan que existe una relación estadísticamente significativa entre rendimiento académico y los componentes de las funciones ejecutivas: fluidez fonológica (p=.01) y flexibilidad cognitiva (p=.01). Por otro lado, la regresión logística arrojó que la fluidez semántica y la inhibición son factores predictivos para el rendimiento académico en un 76.4%.
Discusión y conclusiones.  Se sugiere que las funciones ejecutivas se asocian y a su vez predicen el rendimiento academico en estudiantes de básica primaria, en especial si este es bajo.
Cultural Variation in Aggressive Behavior: A Cross-Cultural Comparison of Students’ Exposure to Bullying Across 32 Countries
Authors: Katsantonis Ioannis
Published: December 2021

Introduction.  The prevalence rates of bullying vary significantly across countries and continents. Specifically, UNESCO estimates that the prevalence rates vary from 22.8% (Central America) to 48.2% (Sub-Saharan Africa). Recently, these differences among countries and regions have been attributed to culture- and country-level variables. Thus, the first purpose of this study is to examine the comparability of bullying in schools across countries. Secondly, a cross-cultural comparison of the latent mean scores of bullying is implemented. Method. The data of 286,481 adolescent students (M=15.78, SD=0.29) from 32 countries were analyzed using multilevel confirmatory factor analyses (MLCFA) and multigroup factor alignment. Results.  Results indicated that the meaning of bullying is equivalent within and between cultures. However, cross-cultural differences in bullying are apparent. East Asian countries have the lowest latent means of bullying, while Southeast Asian countries have the highest means. Anglo-Saxon, Eastern European, Mediterranean, South American, and Middle East countries displayed rather higher scores. Discussion and Conclusion.  These findings underscore the existence of cross-cultural differential responding in bullying measures. Further, the implicit role of culture as an important variable that determines the rates of bullying is underscored.

Delayed Rehabilitation Is Associated With Recurrence and Higher Medical Care Use After Ankle Sprain Injuries in the United States Military Health System
Authors: Rhon Daniel I. , Fraser John J. , Sorensen Jeff , Greenlee Tina A. , Jain Tarang , Cook Chad E.
Published: December 2021

Objective

To investigate the influence of time taken to begin musculoskeletal rehabilitation on injury recurrence and ankle-related medical care use at 1 year after ankle sprain.

Design

Retrospective cohort study of all beneficiaries of the US Military Health System seeking care for an ankle sprain over a 4-year period.

Methods

Individuals were classified according to whether they did or did not receive physical rehabilitation. For those who received rehabilitation (n = 6150), linear relationships (with appropriate covariate controls) were analyzed with generalized linear models and generalized additive models to measure the effects of rehabilitation timing on injury recurrence and injury-related medical care use (costs and visits) at 1 year after injury. The nonlinear effect of rehabilitation timing on the probability of recurrence was assessed.

Results

Approximately 1 in 4 people received rehabilitation. The probability of ankle sprain recurrence increased for each day that rehabilitation was not provided during the first week. The probability of ankle sprain recurrence plateaued until about 2 months after initial injury, then increased again, with 2 times greater odds of recurrence compared to those who received physical rehabilitation within the first month. When rehabilitation care was delayed, recurrence (odds ratio [OR] = 1.28), number of foot/ankle-related visits (OR = 1.22), and foot/ankle-related costs increased (OR = 1.13; up to $1400 per episode).

Conclusion

The earlier musculoskeletal rehabilitation care started after an ankle sprain, the lower the likelihood of recurrence and the downstream ankle-related medical costs incurred. J Orthop Sports Phys Ther 2021;51(12):619–627. doi:10.2519/jospt.2021.10730

We analyzed qualitative (biochemical) and safety indicators (toxic elements) in seeds of cereals, oil crops and products of their processing, the comparison of the biochemical traits of the corresponding crops for two years (yields of 2019 and 2020) was conducted. The purpose of the work is a comparative estimation of qualitative and safety indicators (toxic elements) in seeds of cereals, oil crops and products of their processing (for two years). As material of the research there were used seeds of cereals (wheat, corn), seeds of oil crops (sunflower, soybean) and products of their processing (sunflower cake, sunflower meal, mixed feed for pigs). The analysis was carried out by gravimetric, titrimetric and atomic absorption methods. As a result of the study there were noted the high values of the following indicators: the mass fraction of moisture in seeds of cereals and their processed products; the mass fraction of crude protein and crude fiber in seeds of oil crops and their processed products; the mass fraction of crude fat and crude ash in the seeds of oil crops; concentrations of toxic elements (cadmium and mercury) did not exceed the limit of permissible concentrations. There was practically no change in the concentration in the two-year dynamics in the mass fraction: of moisture in seeds of oil crops; of protein in processed products; of crude fat, crude fiber, and crude ash; the contents of cadmium and mercury in all studied objects.
Image ou événement ? Quelques destins français de la psychanalyse
Authors: pages Varia : Claire
Published: December 2021

Nous souhaitons ici développer une réflexion touchant l’ambivalence de la pensée psychanalytique de l’événement, telle du moins qu’on peut la thématiser à partir des textes de Freud, en présentant les oscillations qui sont les siennes non pas comme un motif d’invalidation mais comme une ressource pour une pensée soucieuse de faire doit et place aujourd’hui à l’événement. Nous proposons d’aborder cette question en partant de la réception des élaborations psychanalytiques de la notion d’événement par la « pensée française ». La théorie psychanalytique semble tantôt interprétée comme ouverture à l’événement, c’est-à-dire appréhendant la vie psychique du sujet comme tributaire d’une expérience, de ce qui lui arrive dans le monde, ce déterminant d’extériorité pouvant relever de l’accident, du contexte, de la rencontre, etc., tantôt comme pensée du fantasme, logique des images sans origine, soit d’une interprétation de la vie psychique du sujet qui indexe celle-ci à des structures ou à des logiques internes autonomes indépendantes de la réalité. L’exigence de penser l’événement qui s’impose à nombre de philosophes du second XXe siècle engage une attitude ambivalente à l’égard de la psychanalyse et cela parfois chez un même auteur. Tantôt la prise en compte de l’événement exige de rompre avec la psychanalyse, tantôt elle impose de s’inspirer de ses modèles et de ses concepts.

Texture classification in aerial photographs using multiscale and multilayer complex networks
Authors: Favorskaya M.N. , Zhukovskaya A.N.
Published: December 2021

Texture classification using oriented complex networks considers the functional connections between topological elements and simulates the complex textures more accurately. In contrast to the classical spatial texture analysis, we offer a novel function of weights in complex networks and a classification method that takes into account the scaling and color of textures. For this, three complex networks represented R, G and B components are built, which provide invariance of color aerial photographs obtained at different times. Comparison of the classification results using the proposed multiscale complex networks and conventional texture analysis based on a statistical approach is given. Also we extended this approach on color aerial photographs using multilayer structure of complex network.

Satellite monitoring of the state and dynamics of disturbed natural and technogenic landscapes in Siberia
Authors: Yakimov N.D. , Ponomarev E.I. , Ponomareva T.V.
Published: December 2021

A method for monitoring recovery process in post-fire and post-technogenic landscapes was proposed based on satellite data in wide spectral range including the infrared bands data. The spectral albedo in short-wavelength bands (MODIS band #1 and #2) was underestimated by 20–48% relative to the background in the first year after the wildfire and remained underestimated by 3–12% after 20 years of vegetation restoration. For the variant of post-technogenic plot with reclamation, the albedo value was corresponded to the dynamics in post-fire plots, while for post-technogenic dumps without reclamation the level of the albedo underestimation remained 45–60% throughout the observation period (> 60 years). A decrease in the spectral albedo of the surface in post-fire areas, due to destruction of on-ground vegetation, provokes excessive heating of surface and upper soil layer. Surface thermal anomalies were evaluated under conditions of changes in the heat-insulating properties of vegetation and ground cover. Temperature anomalies in post-fire plots (overestimation up to 30%) are typical for permafrost conditions of Siberia. Similar process was recorded for both natural (post-fire) and post-technogenic landscapes. Within 20 years of the fire, thermal insulation properties of the vegetation cover restore. Thus, the relative temperature anomaly has reached the background value of 3 ± 1%. In post-technogenic plots conditions are more “contrast” compared to the background, and restoration of the thermal regime takes significantly longer period (> 60 years). Forming “neo-technogenic ecosystems” are characterized with specific thermal regimes of soils compared to the background ones both for reclaimed and for non-reclaimed post-technogenic plots. In averaged, surface temperature has overestimated at least by 10–15% in post-technogenic plots.

In this study fusion of optical (Sentinel-2) and radar (Sentinel-1) imagery is presented for vegetation cover classification in polar Arctic environment of the Western Siberia. Sentinel-1 and Sentinel-2 images were analyzed using parametric rule classification. Results showed significantly improved land cover classification results based on contextual analysis. Synergy of Sentinel-2 bands 4 and 3 and Sentinel-1 dual polarization VV and VH images increased the classification accuracy significantly. Specifically, classification accuracy increased for two classes — Erect dwarf-shrub tundra with 6% and Fresh Water with 10%. The classification accuracy as well test sites were analyzed using in situ data collected during three fieldwork campaigns in August-September (2016–2018) in the surrounding of Bovanenkovo settlement.
Creepex as a parameter of seismo-geodynamic studies based on geo-information systems
Authors: Mikheeva A.V. , Kalinnikov I.I.
Published: December 2021

The GIS-EEDB (the Expert Earthquake Database) and GIS-ENDDB (the Earth’s Natural Disasters DataBase) geoinformation systems implement methods for spatial-temporal analysis of both classical and new characteristics of the seismogeodynamic process. One of the new characteristics is a normalized creepex parameter that can be used in the statistical approach to studying of seismicity to assess a relative contribution of “soft” (creep) and “hard” (explosion) movements to the overall process of focal radiation. In this paper, the following modifications of the creepex parameter are proposed and compared: 1) Cr0 Cr0_world and CrN CrN world as the result of reducing the parameters Cr0 and CrN of each event to the world average values of the creepex, obtained from the polynomial dependence of Cri_world (i = 0, N) on MS_world where Cri_world are calculated based on the world average estimates of Ms_world and mb_world at uniform intervals of the seismic moment (NEIC catalog), 2) Cr_bji as the result of reducing CrN of each event to CrN_bji i.e. to the average for the studied in this work BJI catalog creepex values obtained from the polygonal trend CrN (MS) of all the catalog events. The advantage of using the creepex parameter, reduced to the trend of averaging the magnitudes of the catalog in question, is revealed, since the smallest linear dependence of the creepex on the magnitude is achieved (in comparison with the classical and normalized creepex) and the symmetry in the maximum amplitude of the deviation of the parameter relative to zero is preserved. Examples of the application of the compared parameters in specific seismic-geodynamic studies of aftershock processes of the Molucca and Simushir earthquakes also demonstrate the advantage of the parameter Cr_bji n the observed correspondence of the variations of the latter to the known physical processes in the focal zone of the Kashmir event, studied by the seismic-geodynamic methods of the GIS-EEDB geographical information system.

Published: December 2021

The results of a comprehensive automated monitoring for the hydrological and hydrobiological state of a freshwater Lake Krasilovskoe, conducted since 2013 are given. The experimental dashboard is considered, including the atmospheric-soil measuring complex (ASMC), developed and created in the IMCES SB RAS, Tomsk. An analysis of the dynamics of the lake level during years with contrasting hydrometeorological conditions was performed, which made it possible to identify the main factors that determine the level mode in the spring. In the hydrobiological terms, the dynamics of phytoplankton concentration at different depths in different seasons of the year were investigated. The results of processing Sentinel-1, 2 satellite data and data of natural observations on the distribution of chlorophyll “A” in the surface layer of water sections of the lake water area are discussed.
Analysis of the influence of temperature inversions on the ecological situation in Krasnoyarsk
Authors: Dergunov A.V. , Yakubailik O.E.
Published: December 2021

The paper analyzes the meteorological conditions in the city of Krasnoyarsk in the period from January 1, 2019, to December 31, 2020. The relationship between temperature inversions in the surface layer of the atmosphere and air pollution by suspended solid particles PM25 is investigated. The paper uses a set of meteorological data of the NCEP GFS weather forecast model on the air temperature on three isobaric surfaces of 1000, 925, and 850 Mb; on wind gusts and the height of the atmospheric boundary layer. Data on PM25 solid particle concentrations and wind speed are provided by the air monitoring system of the KSC SB RAS. The relationship between the presence of temperature inversions in the lower layer of the atmosphere and periods of significant air pollution is shown, as well as the dependence of changes in wind speed and the height of the boundary layer of the atmosphere with changes in the average daily PM25 concentration. The results of the data analysis allow us to conclude that there is a high degree of correlation between these parameters. The possibility of using the meteorological data of the NCEP GFS model to study the surface layer of the atmosphere and the periods of its pollution, predicting the deterioration of the environmental situation in Krasnoyarsk, is demonstrated.
Nonlinear approximation of wildfire front temperature on MODIS data for sub-pixel analysis of burning
Authors: Litvintsev K.Yu. , Ponomarev E.I. , Shvetsov E.G.
Published: December 2021

An improved approach to evaluate thermal anomalies characteristics using the pixel-based analysis of the MODIS imagery was proposed. The approach allows us to improve the accuracy in estimating characteristics of active combustion zones comparing to the standard Dozier method. We used the imagery of active wildfires in Siberian forests from the MODIS radiometer acquired in the spectral ranges of 3.930–3.990 and 10.780–11.280 mm (bands 21 and 31, respectively). Nonlinear exponential function was used to describe the approximation of the temperature of combustion zones. Available data of field and numerical experiments were used for validating of the approximation accuracy. Nonlinear approximation of wildfire front temperature allows to determine the portion of the active pixel of the MODIS image with the given temperature excess comparing to the temperature of background cover. This improves the accuracy in extracting of active burning zones as well as in classifying the heat release rate at the sub-pixel level of analysis.

Space observations of the propagation of smoke flares from the chimneys of industrial enterprises provide information on the physical characteristics of the emitted gas-air mixtures. Models for estimating the parameters of the rise of impurities under the influence of dynamic and thermal factors are proposed. The basic relations in the estimation models are the solutions of the equations of hydrothermodynamics of the atmosphere. The case of neutral atmospheric stratification is considered in detail. Using satellite information and meteorological observation data, a numerical study of the stage of ascent of smoke jets from the chimneys of the Gusinoozerskaya State District Power Plant was carried out.

The Atmospheric Infrared Sounder (AIRS) is a hyperspectral instrument with 2378 channels. It is a part of the Aqua space platform equipment. It registers outgoing longwave radiation in the IR-band from 3.74 to 15.4 microns. To correctly retrieve the atmospheric profiles in the presence of cloud structures, AIRS measurement processing scheme uses data from the 15-channel AMSU-A microwave instrument, which is also installed on Aqua. The paper proposes a technology for synthesizing the readings of AMSU-A, that failed in the fall of 2015, by using observations from the 22-channel radiometer of the Advanced Technology Microwave Sounder (ATMS) installed on Suomi-NPP and NOAA-20 satellites. These platforms were launched in 2011 and 2018, respectively. The transition between the coordinate grids of the two instruments was implemented by the “resample” software library, which transferred the radiance temperature values obtained by ATMS radiometer to the AMSU-A irregular measurement grid by means of a Gaussian function. The method was tested for the Aqua and Suomi-NPP neighboring orbits of 2015, when AMSU-A was still operating normally. It is established that the root-mean-square deviation of the radiance temperature values during the transferring of ATMS data to the AMSU-A coordinate grid does not exceed 1%, and the correlation coefficient is 0.98. Using the synthesized AMSU-A readings, reconstructions of the parameters of the atmosphere and the underlying surface were carried out. The analysis of the obtained results showed the suitability of the proposed method of replacing the microwave data from AMSU by the data from ATMS instruments. It should be noted that in the case of a rapidly changing atmosphere, for example, with a strong wind, the use of ATMS observations is possible only if the difference in the passage time of the two satellites does not exceed 10–15 minutes.

Aerospace images with a spatial resolution of less than 1 m are actively used by regional services to obtain and update information about various environmental objects. Considerable efforts are being devoted to the development of remote sensing methods for forest areas. The structure of the forest canopy depends on various parameters, most of which are determined by ground-based methods during forest management works. Remote sensing methods for assessing the structural parameters of forest stands are based on texture analysis of panchromatic and multispectral images. A statistical approach is often used to extract texture features. The basis of this approach is the description of the distributions characterizing the mutual arrangement of image pixels in grayscale. This paper compares the effectiveness of matrix based statistical methods for extracting textural features for solving the problem of classifying various natural and manmade objects, as well as structures of the forest canopy. We consider statistics of various orders based on estimates of the distributions of gray levels, as well as the mutual occurrence, frequency, difference and structuring of gray levels. The results of assessing the informativeness of statistical textural characteristics in determining various structures of the forest canopy are presented. Dependences of the classification results on the choice of distribution parameters are determined. For the quantitative validation of the results obtained, data from ground surveys and expert visual classification of very high resolution WorldView-2 images of the territories of Savvatyevkoe and Bronnitskoe forestries are used.
