The purpose of this study is to fit an appropriate mathematical model to express response variables as functions of the proportions of the mixture components. One purpose of statistical modeling in a mixture experiment is to model the blending surface such that predictions of the response for any mixture component, singly or in combination, can be made empirically. Testing of the model adequacy will also be an important part of the statistical procedure.

A series of mortar using air lime, marble and ceramic sanitary waste aggregates were prepared for statistically designed combinations. The combinations were designed based on the mixture-design concept of design of experiments; this mortar is often used as a filler material in restoration projects. The aim of this work is to find an optimal composition of a paste for the manufacture of air lime mortar with ceramic and marble waste. This investigation aims to recommend mix design for air lime-based mortar, by optimizing the input combination for different properties, and to predict properties such as mechanical strength, thermogravimetric and x-ray diffraction analysis with a high degree of accuracy, based on a statistical analysis of experimental data.

This paper discusses those mortar properties that architects, contractors and owners consider important. For each of these properties, the influence of ceramic and marble waste in the air lime mortar is explored. The flexibility of lime-based mortars with waste materials to meet a wide range of needs in both new construction and restoration of masonry projects is demonstrated.

The objective of the present investigation is to recommend mixture design for air lime mortar with waste, by optimizing the input combination for different properties, and to predict properties such as compressive strength, flexural strength with a high degree of accuracy, based on the statistical analysis of experimental data. The authors conducted a mixture design study that takes into account dependent parameters such as the constituents of our air lime-based mortar where we have determined an experiment matrix to which we have connected the two responses, namely, compressive and flexural strength. By introducing the desirability criteria of these two responses, using JMP software, we were able to obtain a mixture optimal for air lime mortar with ceramic and marble waste.

Current research lacks a clear definition of blended learning in entrepreneurship education (EE), a comprehensive overview of the recent research, and a conceptualization of different types of blends with their respective challenges and advantages. In response to that, the author systematically reviewed the literature on blended learning in EE and developed four archetypes of blends for entrepreneurship educators.

The author conducted a systematic literature review and identified 75 relevant peer-reviewed articles published between 2004 and 2021.

The findings suggest that blended learning is a common yet underexplored and undertheorized phenomenon in EE. The findings display the rationale and motives, educator characteristics, content, teaching methods, student characteristics, and results of blended learning in EE.

The paper is original because it posits blended learning as an independent and unique mode of delivery in EE. In addition, the author suggests four archetypes of blends in EE: the traditional blend, the for-action blend, the in-action blend, and the experiential blend. For each of these blends, the author identified specific advantages and challenges and discussed under which circumstances educators may employ them.

The purpose of this paper is to propose a combination of forecasting methods that enables a holistic understanding of a future situation, given certain influencing variables by a combination of real data and expert knowledge.

The proposal combines two well-known methods: first, system archetypes that correspond to generic structures, allowing us to handle model management issues, and second, system dynamics that offers technical support on a computational level to assess different scenarios or problem solutions.

The case study considers the situation of the mining industry in Chile and its related variables, including four different scenarios. Based on the proposed methodology, the results indicate that: first, the price of copper is paramount for the industry and its effects are not limited to company profits; second, a long period of downfall in copper prices could halt exploration and development projects.

Systemic archetypes are still a subject of research and their application in different fields of knowledge continues to increase to improve this simulation approach.

The case study illustrates the combination of a Vester matrix and initial system archetype models that are enriched using the system dynamics approach. Indeed, the case study aims to understand the consequences of different scenarios based on the problem-driven approach provided by Vester.

The goal of prospective studies of large-scale and complex situations is to model the real situation to obtain solutions that may enhance social welfare.

The proposed methodology contributes to the existing literature by integrating techniques such as the Vester matrix, system archetype modelling and system dynamics simulation, all of which were proposed previously in the literature as independent techniques.

Este artículo propone una combinación de métodos de pronósticos que permite una comprensión holística de una situación futura, dadas ciertas variables de influencia mediante una combinación de datos reales y conocimiento de expertos.

La propuesta combina dos métodos conocidos: (i) arquetipos de sistemas que corresponden a estructuras genéricas, lo que nos permite manejar los modelos, y (ii) la dinámica de sistemas que ofrece soporte técnico a nivel computacional para evaluar diferentes escenarios o soluciones de problemas.

El caso de estudio considera la situación de la industria minera en Chile y sus variables relacionadas, incluidos cuatro escenarios diferentes. Según la metodología propuesta, los resultados indican que i) el precio del cobre es primordial para la industria y sus efectos no se limitan a las ganancias de la empresa; ii) un largo período de caída en los precios del cobre podría detener los proyectos de exploración y desarrollo.

Los arquetipos sistémicos siguen siendo un tema de investigación y su aplicación en diferentes campos del conocimiento continúa aumentando para mejorar este enfoque de simulación.

El estudio de caso ilustra la combinación de una matriz de Vester y los modelos de arquetipos del sistema inicial que se enriquecen utilizando el enfoque de dinámica de sistemas. De hecho, el caso de estudio apunta a comprender las consecuencias de diferentes escenarios basados en el enfoque orientado a los problemas proporcionado por Vester.

El objetivo de los estudios prospectivos para situaciones de gran escala y complejas es modelar la situación real para obtener soluciones que puedan mejorar el bienestar social.

La metodología propuesta contribuye a la literatura existente mediante la integración de técnicas como la matriz de Vester, el modelado de arquetipos del sistema y la simulación de dinámica de sistemas, todo lo cual se propuso anteriormente en la literatura como técnicas independientes.

Drawing from the work of sociologist Niklas Luhmann, this paper analyzes and critiques the ways sociology presents itself as a vehicle for sociological “enlightenment.” It begins with a brief historical account of how sociology has come to describe itself as a science in the name of promoting social justice rooted back to the European Enlightenment of the eighteenth century. Next, the relevant elements of Luhmann's theory of society are explained ground the analysis. Luhmann's critiques of sociology and science are then presented to explain how a Luhmannian understanding of social systems exposes what is missing in sociology's current self-description of itself and its “enlightenment” mission. Building upon Luhmann's observations, a preliminary observational analysis of the communication techniques and technologies of sociology, such as classes, conferences, and publications, is assessed to evaluate the tools sociology uses to engage in communication and “irritate” other social systems. The central question here is, are these tools effective in communicating sociological knowledge in a way that aligns with the aspirational humanistic goals sociology seeks to achieve? The argument then concludes with some remarks about how sociology might potentially overcome its communicative efficacy problem if it takes seriously the insights from a Luhmannian approach to communication and considers alternative forms of communication to reach new audiences. In this way, sociology could perhaps overcome the gap between the facts of its communicational efficacy and its enlightenment norms.

The main aim of this chapter is to analyze the history of entrepreneurship in the footwear cluster during the twentieth century and the dawn of the twenty-first century, around the actions of the manufacturers installed in the city of León, Guanajuato, Mexico. The methodological process was triangulated by three forms of approach to the object of study: the first consisted on the literature review; the second was a longitudinal analysis of socioeconomic and technological indicators; the third was the application of in-depth interviews to five footwear manufacturing entrepreneurs. The main finding was the collaborative model of the footwear cluster in the face of crisis cycles that has historically been facing; this allows to understand the historical challenges of entrepreneurship in the cluster, as well as public policies that have influenced its behavior pattern and the strategies that have outlined its entrepreneurship model.

The purpose of this study is to extract psyllium mucilage and evaluate its antioxidant compounds (in the best extraction condition) and its application in a chocolate drink.

First, the extraction by ultrasonic bath was evaluated, followed by water bath extraction, and as there was no difference between the methods, a water bath experimental design was carried out to evaluate the best extraction conditions for psyllium mucilage, having response variables, yield and emulsion stability. A chocolate drink with psyllium mucilage was produced and evaluated in the best extraction condition to compare with xanthan gum.

The best extraction conditions for psyllium mucilage were 60°C for 2 h and 1:80 ratio (seed:water). It can be verified that psyllium is rich in antioxidant compounds (0.71 mg GAE/g and 6.67 Mmol ET/g by 2,2′-azinobis (3-ethylbenzthiazoline sulfonic acid-6), and 9.65 Mmol ET/g for ferric reducing antioxidant power), which can greatly contribute to its application in food products. The use of mucilage in chocolate drink is feasible, as among its several attributes there was no significant difference between samples, highlighting texture attributes in which mucilage samples did not differ from the control containing xanthan gum (being the grades approximated 6.84).

Psyllium presented several antioxidant compounds that are very desirable in food products. In the chocolate drink, psyllium mucilage showed potential use as a thickener, so it is important for further studies to improve the product’s development, but it is currently feasible to be produced in an industrial scale.

Challenge-based learning (CBL) is a didactic technique that aims to increase the knowledge and skills development of higher education students. The different situations that humanity faces make educational models evolve and adapt to reality and force faculty to be increasingly prepared and open to face current problems. The Tecnológico de Monterrey, the highest ranked private university in Mexico and the 155th in the world (QS World University Rankings, 2021), has implemented the Tec21 Educational Model based on four fundamental pillars: (1) CBL; (2) flexibility; (3) inspiring faculty; and (4) integrated and memorable education experiences. In this chapter, we describe the experience of implementing this education model. Our conclusions so far are that students acquire more knowledge in CBL classes than in face-to-face classes; however, faculty require an adequate training program, and there must be a prior design of the competency assessment instruments. Testing of various assessment instruments found that checklists and rubrics are the most accepted, appropriate, objective, and transparent in CBL courses, based on faculty and students' surveys. Finally, in the opinion of employers, students educated with CBL as a didactic technique have greater acceptance in the working world.

Immigrant women show a higher risk of mental health problems and report higher levels of musculoskeletal disorders. Norwegian psychomotor physiotherapy (NPMP) is a body awareness treatment that has been used to alleviate musculoskeletal disorders and mental distress. The purpose of this study is to explore immigrant women’s participation in a low threshold training group and identify what motivates and affects their attendance and well-being.

The study is informed by a phenomenological approach. The data collection methods consisted of participatory observation and interviews. Observations and interviews were carried out between December 2016 and March 2017.

The findings show that the content and context of the movement group, being able to participate in exercises wearing own clothes and relying on previous body experiences motivate the women to attend and continue in the training program. NPMP inspired group training takes into account women’s cultural preferences and values. The culture-sensitive approach to physical exercise seems to motivate attendance and contribute to social and mental well-being. Low threshold physical programs should, therefore, be considered to provide immigrant women with the opportunity to experience well-being and social participation.

This study contributes to the better understanding and promotion of the physical and mental health of immigrants.
