The Covid–19 pandemic abruptly transformed the way in which human beings throughout the world used to understand the course of their everyday activities. In the academic field, the sanitary emergency brought about the closing of the schools and thus, the implementation of distance education systems. This forced both teachers and students alike to rethink the meaning of notions such as teaching and learning. Beyond statistics and official statements, what was the experience of all those involved in the process like? Particularly, how did teachers live the rupture of their quotidianity and their entry into an everyday life governed by the use of information and communication technologies? Based on information provided by middle and high education teachers, obtained by means of Oral History interviews, this article attempts an answer at these questions in order to throw light on the implications that leaving temporarily classroom based education between March 2020 and June 2021 had on the field of education and to offer elements to reflect upon the feasibility and relevance, along with the shortcomings, of the distance education systems.

The article focuses on the question: Can you create a successful training system between companies located geographically close to each other? The topics are: the possibility of developing a training system within companies (or “intrafirm” training); the positive impact on performance of training derived from geographical proximity; the nature of the interfirm training group; the role in the training offer of foreign and multinational companies; and finally the role of training providers. There is a close analysis of technical and vocational education and training in developing countries, particularly in terms of such important topics as in-company training, interfirm and intrafirm training practices, and training provision as it is related to costs, results, wages and innovations. There is also a degree of focus on more specialized fields such as division of labor, upstream and downstream training, training appropriability, training cluster and spillovers, policies of local and international companies, the role of training providers, and tacit and codified training.

Although the Autonomous Sensory Meridian Response (ASMR) phenomenon has grown notably in Mexico in recent years, local YouTube channels lack effective and continued use of digital marketing strategies and tactics as reflected in their sponsored videos, in contrast to the most popular YouTube ASMR channels, which are essentially English-speaking. After completing a detailed review on YouTube, this article compares both groups and argues that, with a few changes, Mexican ASMR creators can benefit from marketing strategies used by the more popular creators from other countries. By doing this, Mexican creators could ride the nascent wave of attention economy that posits that cognition is a commodity that can be monetized. The analysis of both groups of channels found that Mexican ASMR creators display, more often than not, lower production quality, little knowledge of basic marketing concepts, as well as lower posting frequency than English-speaking videos when compared to their more popular international counterparts. These findings are discussed under the marketing concepts of reach, relevance, and resonance as well as the attention economy construct.

Since the calculations in the inventory models yield a single optimal value without considering a range of values in which the minimums are maintained, a postoptimality methodology is proposed in this study to know the limits of the optimal quantity to order. or produce for which the activities and associated costs are kept to a minimum within the supply chain, in addition to determining how profitable the investment in inventory is, by calculating the Gross margin return on investment (GMROI). Postoptimality analysis is performed over a range of 1 to 10 000 parts to order or produce for the buyer, supplier, and collaborative model inventory models. The results of the postoptimality analysis for the proposed example indicate that the joint inventory model generates a minimum cost within the supply chain when ordering and producing between 1039 and 1082 pieces; It is necessary to highlight that to apply a collaborative model between buyer and supplier, it is necessary to generate an exchange of information, formulation of plans, and negotiations so that both can obtain benefits.

This paper aims to carry out a prospective of the participation of solar photovoltaic (PV) power in the national energy basket by the year 2050. To do this, we used the Delphi method, which is based on consulting experts in the PV sector. Among the results obtained, the following stand out: 1) 89 % of the experts think that the participation of PV electricity will grow in the energy mix of Mexico; 2) PV electricity generation will enrich the national power system for various advantages, such as the implementation of complex PV system projects and interconnected PV farms; 3) 78 % of the experts estimate that the generation of PV electricity will have a positive effect on the gross domestic product. Present analysis suggests that, to materialize the prospective advantages of PV electricity generation towards the year, it is urgent to develop a national plan to promote it.

This article refers to aspects of the conflict developed between february and may of 1983 at the plant of Volkswagen in Monte Chingolo. Based on written sources and two interviews with activists who were protagonists of the conflict, we analyze this dispute between capital and labor through the prism of concepts related to working class culture, and about relations between production and social reproduction areas. In first place, we focus on the role of left parties who had insertion in this company in terms of their importance in the assembly and development of the union representation in the factory of Monte Chingolo and the characteristics of the struggle in 1983. Secondly, we analyze the impact of the conflict in the field of social reproduction. On the one hand, regarding the relationship of the workers with the residents of Monte Chingolo. On the other, in relation to the two activists interviewed, we point out the tensions that were generated with their families due to the duration of the confrontation with the enterprise.

Since the creation of the province of Río Negro -1955- the Radical Civic Union governed, successively, through the two parties formed by the division that occurred after the 'Liberating Revolution' —1955—: The Intransigent Radical Civic Union (UCRI) —1958-1962— and the People's Radical Civic Union (RCRP) —1963-1966— in a national electoral context with Peronism being outlawed, the Peronism only governed between 1973-1976. The objective of the article is to account for the process of 'hegemonic and pragmatic construction' of radicalism in Río Negro, which began with the first government of Horacio Massaccesi —1987-1991—, leaving the bases/pillars of the UCR's predominance for more than two decades —28 years—. The political events and actions on which we will focus, analyzing the political practices deployed by leaders of the Renovation and Change Movement (MRyC), allow us to elucidate the political project. The incorporation/co-optation strategies of both former leaders of the National Line and Peronist leaders from the south of the province, who joined the proposal for a more integrated territory, made it possible for them to stand in the 1987 elections as a 'unit of force'.
