This article analyzes the statements, expressed through their documents, on teacher professionalization of three international organizations: the Organization of Ibero-American States for Education, Science and Culture; the Organization of Ibero-American States for Education, Science and Culture-Unesco and the Inter American Development Bank. The purpose was to identify their explicit and implicit stances on this issue, in the understanding that their discourses, policies and practices of teacher professionalization are part of the processes of production of the social in general and particularly of the educational field. A content analysis of the selected documents was carried out from a critical point of view to the discourse. The results show that a hybrid position on professionalization prevails, although mostly characterized by a teacher-school managerial approach. The conclusions invite us to consider hybridism as a predominant feature of policy-oriented documents addressed to multiple audiences and contexts. [ABSTRACT FROM AUTHOR]

This article presents a study of 52 metallic artifacts made of gold and copper from the archaeological sites of Tamtoc and Rancho Aserradero, both located in the Huastec region of San Luis Potosí, Mexico. These objects served both utilitarian (e.g., needles, fish hooks, and axes) and ornamental (e.g., rings, beads, and bells) purposes. The objective of this paper is to provide a detailed description of the artifacts, present the results of an elemental, non-invasive, and non-destructive in situ analysis performed using X-ray fluorescence, reconstruct the manufacturing processes, and compare these findings with similar objects from other contemporary Mesoamerican regions. This research generated new data and knowledge about the use of metals and alloys in the Huastec region, the technological and cultural decisions behind the creation of these objects, and the exchange networks that facilitated their distribution. The examination of the 52 pieces revealed significant diversity in morphology and elemental composition, which limited the cultural interpretations due to the small sample size. Nevertheless, our results indicate that the studied sites were part of an extensive exchange network with access to metallic objects from the central and western regions of Mesoamerica, as well as Oaxaca and/or Central America.

Plastic transformation enterprises are of great importance due to their impact on others belonging to strategic sectors. However, the high consumption of electrical energy in the processing of these materials contributes negatively to the environment. The objective of this research is to determine the indirect emissions of greenhouse gases based on carbon dioxide, from the fixed consumption of energy in a plastics factory in the province of Holguín, Cuba. The methods used were the techniques for recording and processing data, direct observation, work with groups of experts and surveys, as well as documents analysis. A procedure based on the Tangram Technology methodology was designed to determine the amount of equivalent carbon dioxide that is emitted into the atmosphere. The study was carried out in the period between 2020 and 2022. The main results include the following: energy management at the Holguín Plastics Factory was improved based on the identification of energy saving opportunities in administrative areas, departments and attached premises, implementing an action plan that allowed a decrease in the pollutant load to the atmosphere in the analyzed stage.

This article contributes to developing and consolidating research on the connections between food and gentrification while highlighting the effects of these processes in areas beyond urban life. To achieve this, we draw on the concept of value chains connecting gentrified neighborhoods to rural agricultural communities. In this chain, processes of valorization and devaluation are generated, which unevenly affect the actors involved in the production and consumption of food. The paper focuses on the conflicts and contestations along the value chain of gentrification, putting interdisciplinary contributions into dialogue while presenting four cases from secondary sources. These cases are illustrative of how these processes operate at different levels, territories, and scales: signature coffee, as a symbol of distinction in gentrified neighborhoods; the avocado from its gastronomic manifestation as avocado toast; wine, from the touristification of its production to valorization strategies in urban consumption; and quinoa, from the patenting of new varieties to the development of markets that exclude large sectors of the population. The boom in the circulation of these foods has the effect of capital accumulation by dispossession in both rural and urban areas and in both production and consumption processes.

The article analyzes some theoretical elements that shed light on the understanding of the nature of the state and the category "state-form", which seek to identify in the "value-form" the element that unifies the economic and political moments of capitalist society that warn that, within the polycrisis of capital, an intensification of the state can be found to respond to the untimely rhythm of capital in its dynamics of accumulation, with the growth of its violence, particularly recognized by the rise of neo-fascism. Three parts constitute the article. The first presents the characteristics of the dimensions that make up the polycrisis, to make clear its relationship with the capitalist state--state-form--which encourages the increase in violence. The second part deals with the understanding of the state in the capitalist production process, based on the triad "value-form", "state-form", and "empireform". The third part presents elements to understand the phenomenon of growing violence, with the generalization of political movements characterized as neo-fascist. [ABSTRACT FROM AUTHOR]

The purpose of the work was to characterize, from the chemical, physical, granulometric and mineralogical point of view, an industrial residue of calcium hydroxide generated in the acetylene manufacturing process. Samples were first analyzed without neutralization; then the same procedure was performed using 98 % purity sulphuric acid. For both cases, the heating temperatures used were 500 °C and 900 °C. To identify the phases, diffraction patterns were obtained using copper radiation source (CuKa, 1 = 1.5418 Å). It was determined that residual contains CaO and MgO, which guarantees its purity; heated at 500 °C, and without neutralizing, calcium hydroxide is transformed and there is loss of water and carbonate at 900 °C. In both untreated and neutralized waste, calcium hydroxide is present. [ABSTRACT FROM AUTHOR]

Social media networks, especially those where the use of images plays a key role, are a fundamental tool for fashion brands to be perceived as sustainable. The purpose of the present investigation is to analyze the elements and colors used by the 10 fashion corporations with the highest scores in the sustainability rankings when they share photographs and illustrations to Instagram and analyze the differences between publications related to sustainability and those that are not. Based on the history of posts from the 61 brands that make up these 10 corporations (277,955), those that include a term related to sustainability were identified, obtaining a sample of 12,639 publications. Next, an automatized image recognition was made using the Python Inception V3 library and the colors used were analyzed using the PIL and colorsys libraries. Even though clothing and footwear are the elements most frequently displayed when choosing a single image, in half of the cases the brands combine various types of images to reinforce the sustainable message with images of nature, sport, animals or food. In sustainable content, this trend is more pronounced in a communication strategy aimed at reducing the prominence of the final article, subjected to an industrial manufacturing process, and providing a more benevolent context from the point of view of sustainability. In addition, there are chromatic differences between sustainable content and those that are not. In all cases, the most used color is red, but in sustainable content the presence of cyan and green increases, closely linked to images of nature and landscapes. [ABSTRACT FROM AUTHOR]

This paper examines and discusses potential factors that may trigger authenticity in animated immersive environments. Our discussion draws upon three forms of authenticity, categorized as objective, constructive or symbolic, and existential authenticity. To explore these ideas, we present three case studies drawn from the authors' own research deploying immersive media in different contexts (educational, historical, and political). The aim is to interrogate how authenticity is conceived and constructed on three levels -- authenticity of narrative, authenticity of environment, and authenticity of action -- during the design and production process. We start by defining the concept of authenticity with reference to previous work within the fields of journalism and tourism, and then explore its specification in animated virtual reality through the case study discussion. One important conclusion from our analysis is that authenticity markers are needed to enable users to verify the information presented and trust the educational content. [ABSTRACT FROM AUTHOR]

Production scheduling is one of the most important tasks in manufacturing systems since it allows the allocation of jobs with a certain number of available resources. In the production and service industries, meeting the established commitments with the different customers and production deadlines can lead to higher levels of satisfaction and market competitive advantages. On the other hand, one of the main industries worldwide is the coffee industry. Indeed, coffee is the second most traded commodity in the world. Therefore, this research addresses the optimization of the total tardiness in the scheduling of jobs in parallel machines for a case study in a coffee roaster. This is an NP-hard problem where each job requires the roasting process and, in addition, has an associated delivery time. Each job's processing time depends on the machine that is designated and not all machines can run all jobs. We present the mathematical model to describe the problem using mixed integer linear programming and then it is implemented in Python. Additionally, a mate heuristic model based on the ATC heuristic is proposed in order to reduce the computation time and to reach solutions close to the optimum. This model was evaluated with one thousand instances of real data from the roasting process. The Gurobi optimizer was used to solve the problem. The exact method shows high computational times, so we proposed to first perform the sequencing of jobs and then assign them to the machines by means of a simplified mathematical model. By using the proposed mate heuristic model, an average reduction of 53.98% of the execution time is achieved and with respect to the solution delay, this model achieves a median of 0.0% with respect to the optimum.

In a highly competitive business environment, companies are looking for ways to increase efficiency and reduce costs in their production processes. The automation of industrial processes is benefiting significantly from technological advances, offering alternatives to achieve these objectives more effectively and efficiently. Automation and artificial intelligence have played a key role in transforming industrial operations, driving progress and efficiency across different sectors. Artificial intelligence, in particular, has impacted the industrial sector, driving advances in robotics, automation and operational efficiency, but also raising challenges in relation to social and economic aspects. Therefore, this work aims to address how artificial intelligence in the automation of industrial processes is essential in day-to-day industrial operations, as it allows repetitive, dangerous or complex tasks to be carried out more efficiently and safely. It involves the use of automated systems and equipment to carry out activities such as assembly, transportation, packaging, quality control, among others. [ABSTRACT FROM AUTHOR]

The objective of the article is to problematize the conception of the relationships between the world of work and training. It ends with a 'provisional order' of knowledge that are mobilized in the various spheres of work(s). The article starts with a brief characterization of the structure of paid work in Argentina, which is the legitimate reference to the knowledge for the work force; secondly, an approach to the diversity of worlds of work (paid, domestic and community) is organized where relationships and ways of knowing in production are developed; in the third step, the tensions between hierarchies of knowledge and production processes are presented whereof, in the following section, the intersections between spheres of work and the crossing of knowledge between them are elaborated; it ends with a provisional ordering of types of knowledge in relation to the different worlds of work.

Improving efficiency in the application of irrigation water, due to its scarcity, is a matter of concern to all decision-makers in the country, since it is not possible to continue managing the precious liquid with current guidelines. Studying the efficiency of irrigation in Cuban agriculture as a combination of resources will allow us to know where the application of water will be of greater benefit, always in combination with other resources used in the production process. In this context, the use of non-parametric techniques such as data envelopment analysis is convenient, given its flexibility and ability to handle the productive characteristics of entities. The analysis of irrigation by means of DEA, will allow to evaluate where the management of the water is carried out in a more efficient way. [ABSTRACT FROM AUTHOR]

Objective: To know the current state of research on the evaluation of the Carbon Footprint (CF) of coffee and its value chain. Methodology: A systematized review of literature from international bibliographic databases was conducted, identifying five aspects; 1) place of assessment, 2) scope of the assessment, 3) methodology used, 4) result of the CF, and 5) functional unit of measurement considered. Results: Sixteen articles from 16 countries were reviewed, evaluating different scopes of the coffee production chain. Six different methodologies were applied, including international standards and specialized software. The calculated CF ranges from 0.12 kg/CO2eq to 14.61 kg/CO2eq depending on the scope of the research in the coffee production chain. Limitations: Scarce collection of publications obtained in the systematized search process. Conclusions: There is a need to increase research on the subject in small-scale production areas, since most of the methodologies and applications have focused on areas where the grain production and technification are concentrated, leaving aside other production areas that require attention with respect to their production processes.

The article analyzes two magazines produced by the Capuchin friars in two different regions, El Adalid Seráfico de Sevilla and El Heraldo Seráfico de Cartago, using a comparative methodology. It proposes to study these publications using the communication circuit developed by Robert Darnton, with an emphasis on the people involved in the processes of production, distribution, and consumption. Since the late 19th century, the Capuchin Order began financing magazines with doctrinal content and printing workshops wherever they were present. The objective of this study is to analyze the Capuchin magazines from a comparative perspective. [Extracted from the article]

Technological tools focused on small businesses allow information to be processed by detecting errors or gaps in the business with the purpose of creating strategies to improve production and processes that can differentiate themselves from the rest of businesses that do not apply these tools in their favor, by obtaining data from sales or any change related to a service in the sector. A mixed qualitative-quantitative approach was used, collecting data on the use and applications of technological tools, surveys will be carried out with the employees and owners of the microenterprise on technological applications. The results confirm the relevance of the use of technological devices, where entrepreneurs or microbusiness owners decide to change from conventional business to use tools that help them improve their establishments. The entrepreneur explores tools that allow them to create, promote and sell products and services in a more agile and orderly way, since with the use of technological tools they can have the possibility of increasing their sales numbers.

The case study takes place, in the municipality of Netzahualcoyotl, Mexico, during the 1980s and 1990s, and is characterized by the cultural emergence of the Chavos Banda. To understand the impact this movement had on the social production of habitat in the municipality, eight interviews were conducted with former members of the bands. We assert that the cultural practices of young people, framed within an urban order, are an important part of the process of social production of habitat in low-income urban developments, such as the case of the municipality of Netzahualcoyotl.

Hausmann, Rodrik, and Klinger determine the quality of exports according to the level of complexity of economies. The method is based on the closeness of goods produced within a country, which is established by the production structure. Products simultaneously present in a country’s production structure are close. Products are specified according to the Standard International Trade Classification (sitc) and, more recently, to the Harmonized System. We argue that, in the context of increasing international production fragmentation, the complexity of economies should be established in line with their specialization by stages in the production processes. The quality of Mexican exports is estimated based on indicators of export composition, origin of the value of exports, backward linkages of exporting sectors, types of exported goods and their use by importers, capital ownership of exporting firms, research, and development in exporting sectors, as well as unit prices.

In this paper, the results carried out about a study over the possibilities of the Predictive Functional Control (PFC) are presented. The French professor Jacques Richalet and his collaborators developed the PFC. The results presented were obtained, when PFC is applied to industrial processes with complex dynamics such as high order, integral effects in the direct step that make the process asymptotically unstable in open loop and the undesirable phenomena of delay and inverse response. The main objective of the study is to demonstrate the potential offered by the PFC algorithm, in its simplestform, for the control of such processes. To this end, a methodology for synthesizing the PFC controller is developed based on the postulates and principles proposed by the precursors of the method, applied to several real case studies. In all cases, completely satisfactory results were obtained by means of simulation in Simulink-MatLab and finally the results of applying the method to the temperature control of the TCLab minilaboratory developed at the University of Utah are compared. This verifies the real possibilities of the FPC as a prominent alternative to control of real process. [ABSTRACT FROM AUTHOR]
