The blood donation process is essential for health systems. Therefore, the ability to predict donor flow has become relevant for hospitals. Although it is possible to predict this behaviour intention from donor questionnaires, the need to reduce social contact in pandemic settings leads to decreasing the extension of these surveys with the minimum loss of predictivity. In this context, this study aims to predict the intention to give blood again, among donors, based on a limited number of attributes. This research uses data science and learning concepts based on symmetry in a particular classification to predict blood donation intent. We carried out a face-to-face survey of Chilean donors based on the Theory of Planned Behaviour. These data, including control variables, were analysed using the decision tree technique. The results indicate that it is possible to predict the intention to donate blood again with an accuracy of 84.17% and minimal variables. The added scientific value of this article is to propose a more simplified way of measuring a multi-determined social phenomenon, such as the intention to donate blood again and the application of the decision tree technique to achieve this simplification, thereby contributing to the field of data science.

The lack of blood donors is a global problem that prevents the demand for blood prompted by an ageing population and increased life expectancy from being met. The aim of this study was to conduct an initial exploration of the reasons for using digital platforms in blood donation. Using a Theory of Planned Behaviour (TPB) framework, microdata for 389 participants from Latin American countries and Spain, and Partial Least Square-Structural Equation Modelling (PLS-SEM), the study obtained three main prediction paths. The first two started from feelings of trust in the digital community and a positive mood state associated with a modern lifestyle, and they were linked to attitudes and behavioural control in the explanation of the intention to donate and actual blood donation. The third path started from modern lifestyles, and was linked to the subjective norm in the prediction of intention and actual donation. These paths represent one of the very first attempts to predict intentions of donation and collaborative donation by taking a PLS-SEM approach. By determining the paths underpinning collaborative blood donors’ motives, the results of this study provide strong support for the usefulness of the TPB model within the context of digital platform use and blood donation.

Many factors and aspects of the construction and operation of buildings depend on climatic parameters and climatic zones, so these will be fundamental for adapting and mitigating the effects of climate change. For this reason, the number of climate-oriented publications in building is increasing. This research presents an analysis on the most-cited climate-oriented studies in building in the period 1979–2019. The main themes, the typologies of these investigations and the principal types of climatic zoning used in these studies were analysed through bibliographic and manual analysis. A broad spectrum of themes directly and indirectly related to climate and climatic zones and buildings was demonstrated. It was found that 88% of all climate-oriented investigations, to one degree or another, are within the scope of the general topic of energy conservation. A thorough understanding of all climate-dependent aspects will help in designing dwellings appropriately in different climate zones. In addition, a methodology that facilitates the establishment of a typology of climate-oriented research is presented. This typology can be used in future research in different scientific areas. It was also revealed that the climate zones of the National Building Codes of China, the USA and Turkey prevailed in the studies analysed.

In the present paper a novel process of the coal ash treatment was developed and analyzed: a high-pressure autoclave HCl leaching of the coal bottom and fly ash from an Omsk coal-fired power plant. This process was applied to extract aluminum from the coal ash into a chloride solution, which can further be used as a coagulant for water treatment. The Al extraction efficiency in this process can reach over 90 % at certain process parameters discussed in the present study. Kinetics of the leaching process were evaluated using different kinetic (e.g. shrinking core) models. A semi-empirical equation was proposed for description of the kinetics of the leaching process as a function of the HCl concentration, solid-to-liquid ratio and temperature. Different mechanisms of the leaching process were also discussed and proposed. Water treatment by the obtained Al-chloride showed good results compared to an industrial coagulant; the treated water parameters were within the limits recommended by the World Health Organization for drinkable water.

Globally, xenocentrism has emerged as a significant concept to understand consumer behavior regarding local and foreign products. In this context and based on a sample of Colombian customers, this investigation aims to analyze both the direct and indirect effects of xenocentrism on the consumer purchase intentions of imported products through product attitudes and perceived product quality. Xenocentrism was measured using the XSCALE, and the research model was analyzed with partial least squares structural equation modeling. The result indicates that xenocentrism has a positive direct effect on purchase intentions, perceived product quality, and product attitudes. The analysis also shows that product attitudes will partially mediate the effect between xenocentrism and purchase intentions. In light of these findings, xenocentrism in Latin America arises as a solid construction to explain consumer behavior, mainly when individuals’ beliefs generate a positive appreciation of the purchase of imported products that compete in local markets. Moreover, these results permit designing sustainable marketing strategies that are more suited to the xenocentrism of Latin American consumers.

La investigación aborda el efecto de distintas variables en el precio de servicios hoteleros en Chile, examinando si existe una correlación entre el puntaje asignado por los usuarios a un servicio y el precio de dicho servicio. Un grupo de 145 hoteles disponibles en Booking.com para la ciudad de Santiago de Chile fueron examinados para conducir el análisis. A partir del uso de un modelo de regresión lineal multivariada, estos hoteles fueron examinados en tres temporadas (alta, media y baja). Los resultados muestran una correlación positiva entre el precio de los hoteles y el puntaje otorgado por los usuarios. Además se encontraron otras variables que inciden en el precio, tales como localización geográfica y número de comentarios. Los resultados sugieren que la industria hotelera debiera prestar una mayor atención a la gestión de los comentarios para una mejor posición de precios en el mercado. Esto implica gestionar una política de post venta para monitorear la experiencia de los huéspedes y adoptar las correspondientes medidas correctivas para mejorar la experiencia del usuario.

Este artículo tiene como objetivos analizar las relaciones entre sindicatos y distintos actores en la región de Los Ríos en Chile, e identificar los principales factores que influyen en la disminución de los trabajadores afiliados. Se desarrolló una investigación de tipo descriptiva, con diseño no experimental, transeccional, de campo. Se aplicaron cuatro cuestionarios distintos a 72 actores que interactúan con los sindicatos como son: trabajadores, sindicalizados y no sindicalizados, empresarios de distintas organizaciones de la región y entidades del Estado. Los resultados revelan como principales causas de la baja afiliación a sindicatos: los beneficios que adquieren los sindicalizados son los mismos otorgados a los que no están sindicalizados; las altas cuotas de afiliación que algunos sindicatos establecen; el tiempo que demandan las reuniones; y una discriminación en ambos sentidos, entre los trabajadores sindicalizados y los no sindicalizados. Se concluye que las relaciones entre los sindicatos y los distintos actores involucrados son buenas o excelentes, por lo que el sistema tiende a la concertación y no a la confrontación y, asimismo, que la desafiliación se explica debido a que los trabajadores dejan de sentirse identificados con los dirigentes y/o no están de acuerdo con sus visiones, estilo de liderazgo y gestión.
