Published: January 2022

The outbreak of COVID-19 has made scientists from all over the world do not measureefforts to understand the dynamics of the disease caused by this coronavirus. Several mathematical models have been proposed to describe the dynamics and make predictions. This work proposes a mathematical model that includes social isolation of susceptible individuals as a strategy of suppression and mitigation of the disease. The Susceptible-Infectious-Isolated-Recovered-Dead (SIQRD) model is proposed to analyze three important issues about the dynamics of the disease taking into account social isolation: when the isolation should begin? How long to keep the isolation? How to get out of this isolation? To get answers, computer simulations are provided and their results discussed. The results obtained show that beginning social isolation on the 10th or 15th days, after confirmation of the 50th case, and with 70% of the population in isolation, seems to be promising, since the infected curve does not grow much until it enters the isolation and remains at a stable level during the isolation. On the other hand an abrupt release of the social isolation will imply a second peak of infected individuals above the first one, which is not desired. Therefore, the release from social isolation should be gradual.

Published: January 2022

In the last years, the agricultural systems based on Crop-Livestock-Forestry integrationhave emerged as a potential solution due to its capacity to maximize land use and reduces the effects of high temperatures on the animals. Within these systems, there exist an interest in technological solutions capable of monitor the animals in real-time. From this monitoring, one of the main interest is to know if an animal is in the sun or in the shade of a tree by using some environmental measures. However, as there is a possibility that the weather is cloudy, real-time monitoring also needs to identify this case. That is, the realtime monitoring also needs to differentiate the shade of a tree from a cloudy weather. The interest in this kind of monitoring is due to the fact that an animal that remains a long time under a shade of a tree provides substantial insights to indicate if this is in thermal stress. This information can be used in decision-making with the goal to reduce the impact of the thermal stress and consequently to provide welfare to the animal and reduces the financial losses. As a solution to identify if an animal is in the sun or in the shade of a tree or if the weather is cloudy, we developed an electronic device, used to capture values of environmental variables, which integrated with a mathematical model predicts the shade state (sun, shade or cloudy) where the animal can be found. We illustrate the performance of the proposed solution in a real data set.
Implementation of the Green-Ampt Infiltration Model: Comparative between different numerical solutions
Authors: Mendes T. A. , Sousa Júnior S. F. , Pereira S. A. S. 
Published: January 2022

The phenomena of infiltration and the percolation of water in the soil are of fundamental importance for the evaluation of runoff, groundwater recharge, evapotranspiration, soil erosion and transport of chemical substances in surface and groundwater. Within this context, the quantitative determination of the infiltration values is extremely important for the different areas of knowledge, in order to evaluate, mainly the surface runoff. Several types of changes in vegetation cover and topography result in significant changes in the infiltration process, making it necessary to use mathematical models to assess the consequences of these changes. Thus, this article aims to implement the Green-Ampt model using two numerical methods - Newton-Raphson method and W-Lambert function - to determine soil permeability parameters - K and matric potential multiplied by the difference between initial and of saturation - comparing them to the real data obtained in simulations using an automatic rainfall simulator from the Federal University of Goiás - UFG. The Green-Ampt model adjusted well to the data measured from the rain simulator, with a determination coefficient of 0.978 for the Newton-Raphson method and 0.984 for the W-Lambert function.

Editorial: Monográfico Creatividad, curiosidad y pensamiento innovador en Educación Comparada en relación a las nuevas normas del siglo XXI
Authors: Hayhoe Ruth , García Ruiz Mª José , Martínez Usarralde Mª Jesús 
Published: January 2022

La comunidad científica apela y reivindica actitudes epistemológicas de creatividad y curiosidad, y el empleo de recursos innovadores en momentos en que, ontológicamente, se ha llegado a un estancamiento. La superación de la denunciada “parálisis” de la Educación Comparada (Carney, 2010, p. 126), reclama el empleo académico de dichas actitudes. Así ha sido formulado por académicos que proponen nuestra implicación en “un pensamiento nuevo y fresco sobre lo que estudiamos; los conceptos interpretativos, marcos y teorías que desarrollamos en nuestro trabajo, las influencias y contextos que moldean el trabajo que realizamos como comparatistas” (Larsen, 2013), además de promover “la importante tarea de crear una Educación Comparada con una problemática intelectual compleja” (Cowen, 2009).
No obstante, los actuales momentos históricos, en el inicio de la tercera década del siglo XXI, revelan también paradojas y realidades dicotómicas de difícil consenso y coexistencia conjunta. Así, la ya extensa globalización posibilitada por las nuevas tecnologías, choca con la aún vigente ‘cultura escolar” (Viñao XXX) propia y específica de cada Estado-nación. El postmodernismo, con sus virtudes (ie. lucha contra la injusticia social) y sus defectos (estéril relativismo), se ve frenado por las posturas epistemológicas que reclaman la aún vigencia del proyecto moderno.
AUTOBIOGRAFÍA / AUTOFICCIÓN EN EL ÁMBITO HISPÁNICO. FRONTERAS Y ESTUDIOS RECIENTES
Authors: LUQUE AMO Álvaro 
Published: January 2022

En la teoría literaria sobre escritura autobiográfica y autoficcional ha predominado cierta confusión en el empleo de las etiquetas y solamente en los últimos años parece haberse generalizado una distinción definitiva entre ambos discursos narrativos. Este artículo tiene como objetivo establecer un recorrido de la evolución experimentada por la dicotomía autobiografía / autoficción. Para ello parto de los orígenes de lo autoficcional, analizo la evolución de este debate y finalmente me centro en las últimas publicaciones de relevancia. La intención es dar a conocer nuevas ideas, todavía poco discutidas en el ámbito hispánico, que desarrollan y amplían los planteamientos de autores asentados en este campo de estudio.
Abstract: In the literary theory on autobiographical writing and autofiction, there has been a certain degree of confusion in the use of labels; only recently, a clear distinction has been drawn between them both. This article aims to establish a path of evolution for the dichotomy autobiography / autofiction. I will start from the origins of autofiction, will later analyse the evolution of the theoretical debate, and will finally focus on the latest relevant publications. Therefore, the article will make known new ideas, still little discussed in the Hispanic sphere, which develop and extend the approaches of authors based in this field of study.
Gender roles and women’s mental health: their influence on the demand for psychological care

Published: January 2022

The prevalence of certain diagnoses, such as eating disorders, depression, anxiety, and borderline personality disorder, is higher among women than among men. When it comes to women’s mental health, focusing on social aspects influencing the way women fall ill becomes crucial. Using a sample of 368 women, we studied the classification ability of a number of clinical variables and sociocultural factors (conformity to gender norms) in order to ascertain whether or not women were receiving psychological care and determine the importance of each of the variables when predicting which women were receiving therapy. Our results showed that women were more likely to be receiving psychological treatment when scoring high on certain clinical variables (such as Suicidal Ideation and Borderline Features) and on a number of variables related to conforming to gender norms (Care for Children, Nice in Relationships, and Sexual Fidelity). Therefore, we believe that integrating the gender perspective into educational, health-related, and psychological care programmes is essential so that gender roles can become more diverse and less constricting of people’s potential, resulting in improved health.
La prevalencia de determinados diagnósticos –trastorno de la conducta alimentaria, depresión, ansiedad y trastorno límite– es superior en mujeres que en hombres. Considerando la salud mental en mujeres, resulta imprescindible poner el foco en los aspectos sociales que influyen en la forma de enfermar. Se estudia en una muestra de 368 mujeres la capacidad de clasificación de algunas variables clínicas y factores socioculturales (conformidad con las normas de género) para determinar si una mujer está recibiendo asistencia psicológica o no, así como la importancia de cada una de esas variables a la hora de pronosticar qué mujeres estarían recibiendo terapia. Los resultados mostraron que cuando las mujeres puntúan alto en algunas variables clínicas (como Ideaciones Suicidas y Rasgos Límites) y en algunas relacionadas con conformidad con las normas de género (Cuidadora de Niños/as, Agradable en las relaciones y la Fidelidad Sexual) era más probable que estén recibiendo tratamiento psicológico. Por lo tanto, se considera que la inclusión de la perspectiva de género en programas de educativos, de salud y atención psicológica es fundamental para que los roles de género puedan ser más diversos y constriñan menos las potencialidades de las personas, lo que influirá en que tengan una mejor salud.

In this study, the psychometric properties of the Spanish version (Bakker et al., 2018) of the Job Crafting scale of Tims et al. (2012), was analyzed in a Latin American population. We applied the scale to a sample of 903 employees (42.6% women & 57.4% men) from Colombia and Ecuador. Reliability and validity were examined. The results of the confirmatory factor analysis showed an adequate fit both in Colombia (CFI = .916, TLI = .900, IFI = .917, RMSEA = .060) and in Ecuador (CFI = .918, TLI = .903, IFI = .919, RMSEA = .064), in the four-factor structure of the original scale. Evidence of validation, related to criterion for psychological well-being for the dimensions of increasing structural resources and increasing challenging demands, was found. The Spanish version of the scale demonstrates its usefulness for research in the Latin American context.

Work characteristics and occupational health: validation and proposal of a shortened version of the Work Design Questionnaire
Authors: García Izquierdo Antonio León , Castaño Pérez Ana M. 
Published: January 2022

Interest in the study of work characteristics to explain how an individual's relationship with the work environment can lead to maladaptive responses has taken on renewed importance in the light of increasing concern for the development of healthy organizations and organizational diversity. This study aims to develop a shortened version of the Work Design Questionnaire (WDQ) with a view to facilitating its use and interpretation. The psychometric properties of this shorter questionnaire were tested in a multi-sectoral sample of workers in Spain, with due consideration given to the gender measurement invariance. For this purpose, we applied the questionnaire to a sample of 500 workers and analyzed the relationship between the answers provided to WDQ and specific occupational health variables (satisfaction, well-being and emotional exhaustion). Results showed adequate reliability and criterion-oriented validity for the shortened version of the WDQ, that is, the WDQ18-S, as well as evidence of factorial invariance across gender. We then discuss the results and their implications for the application of the WDQ in further research and the field of occupational health and psychosocial risks prevention.

Las propiedades psicométricas de este cuestionario reducido se probaron en una muestra multisectorial de trabajadores en España. Para ello, aplicamos el cuestionario a una muestra de 500 trabajadores y analizamos la relación entre las carácterísiticas del trabajo y las variables seleccionadas de salud ocupacional (satisfacción, bienestar y agotamiento emocional). Los resultados mostraron una fiabilidad y una validez orientada al criterio adecuadas para la versión abreviada del WDQ, esto es, el WDQ18-S, así como evidencia de invarianza factorial de género. Posteriormente se discuten los resultados y sus implicaciones para el uso del WDQ en el ámbito aplicado e investigador de la salud ocupacional y la prevención de riesgos laborales.
Formulations
Authors: Witt Andrew 
Published: January 2022

An investigation of mathematics as it was drawn, encoded, imagined, and interpreted by architects on the eve of digitization in the mid-twentieth century.
In Formulations, Andrew Witt examines the visual, methodological, and cultural intersections between architecture and mathematics. The linkages Witt explores involve not the mystic transcendence of numbers invoked throughout architectural history, but rather architecture's encounters with a range of calculational systems—techniques that architects inventively retooled for design. Witt offers a catalog of mid-twentieth-century practices of mathematical drawing and calculation in design that preceded and anticipated digitization as well as an account of the formal compendia that became a cultural currency shared between modern mathematicians and modern architects.
Witt presents a series of extensively illustrated “biographies of method”—episodes that chart the myriad ways in which mathematics, particularly the mathematical notion of modeling and drawing, was spliced into the creative practice of design. These include early drawing machines that mechanized curvature; the incorporation of geometric maquettes—“theorems made flesh”—into the toolbox of design; the virtualization of buildings and landscapes through surveyed triangulation and photogrammetry; formal and functional topology; stereoscopic drawing; the economic implications of cubic matrices; and a strange synthesis of the technological, mineral, and biological: crystallographic design.
Trained in both architecture and mathematics, Witt uses mathematics as a lens through which to understand the relationship between architecture and a much broader set of sciences and visual techniques. Through an intercultural exchange with other disciplines, he argues, architecture adapted not only the shapes and surfaces of mathematics but also its values and epistemic ideals.

Introduction: COVID-19 is one of the huge health burdens on the earth in the recent times. Massive campaigns on the adherence to standard operation procedures (SOPs) have been emphasized by the Government of Uganda and even the county has been put in two lockdowns to curtail the spread of this disease. Despite all these efforts, market vendors in Sironko district have seemingly not complied with these SOPs and this makes them potential hotspot for disease transmission, but no qualitative study has so far been documented. Therefore, the current study investigated the adherence of SOPs for COVID-19 amongst market vendors in this area.
Methodology: A qualitative survey research design was adopted and a total of 53 participants, selected by both purposeful and simple random were involved. Interview, focus group discussion and observations techniques were used in data collection. The date was analyzed by the statistical software called MedCalc, version 20.0008
Results: The result showed that 65 % were females, most were aged between 29 females aged between 31-40 year took part in the study contributing 55% to the total subjects and married and of which 37 (70 %) were married. The market experienced challenges of inadequate & inappropriate facilities for SOPs but water was abundant (45, 85 %). All the SOPs for COVID-19 were flouted in these markets.
Conclusions: Market vendor rarely adhered to SOPs for COVID-19 and this makes them a potential source for transmission of COVID-19 to the local communities in the entire sub-regions. Therefore, there is need for department of production in Sironko district to re-enforce observance to SOPs guidelines for COVID-19 in this area.

Authors: Ananth P. , Koland Marina , Deshpande Sridhar , Mahendra G. S. 
Published: January 2022

Background: The main purpose of this study was to maximize the efficacy of fenugreek seed extract by loading it in an optimised solid lipid nanoparticles (SLNs) formula.
Methods: To achieve an effective extraction method, preliminary studies were carried out to confirm the extract, and the extract was standardised using trigonelline. The influence of independent variables lipid concentration (X1), surfactant concentration (X2), and cosurfactant concentration (X3) on dependent variables particle size (Y1) and entrapment efficiency (Y2) was also studied and optimised using the Box–Behnken design. Melt emulsification followed by ultrasonication was used to prepare SLN formulations. To understand the effect of independent variables on the dependent quality parameters, response surface plots and mathematical equations were produced.
Results: The results confirmed that soxhalation was the most suitable method for extraction of fenugreek seeds, confirmed by standardization. Further optimization revealed that particle sizes ranged from 193.4 to 312.3 nm, with entrapment efficiencies ranging from 61.2 to 74.32 percent. This implies that the developed formulations can be used for further in vitro and in vivo characterizations.
