Languages: Spanish, Castilian

DOI: 10.17160/josha.9.3.821

This thesis addresses the unionism deployed by Section 22 of the National Union of Education Workers (SNTE) against the Education Reform promoted during the presidential term of Enrique Peña Nieto (2012-2018). The reform established a set of criteria determining hiring, contract renewal, and promotions for teachers within the education system. Section 22 of the SNTE, union that represented public education workers from Oaxaca State, questioned the modifications and raised a belligerent unionism against the education measures. The union carried out extensive strikes, used strong repertoires of collective action, proposed a form of organization based on assemblies and sought to articulate its action against the reform with other demands raised by different subaltern groups.

Cognitive control tasks allow the analysis of data provided by experimental processing mechanisms, in which one must respond under conditions of congruence-incongruence stimuli. The present critical review aims to analyze the main studies of the Simon Task cognitive control task, with special attention to the research method employed. The literature search was carried out using the PubMed and MedLine databases. Five studies conducted between 2000 and 2020 were selected. There is a remarkable growth in experimental research with the use of cognitive control tasks, especially classic tasks such as the Stroop, the Go/No Go and Eriksen's Flanker, which due to their wide description in the literature can help to strengthen discussions in researches that want to measure this variable.

Las mujeres y el apocalipsis - Women and the Apocalypse

Sol Minoldo

Languages: Spanish, Castilian

DOI: 10.17160/josha.9.2.809

Both overpopulation and extinction would be the (extreme) results of moving away from that equilibrium point in which the population reproduces enough to guarantee its 'replacement': it neither grows nor decreases, but keeps the number of individuals stable by replacing those who die with those who are born. In the past, there was high concern about overpopulation and the goal was greater birth control. However, at least in Europe, things have changed. To the concern of many, fertility rates in some countries are below 2 children per woman. In addition, the demographic explosion of the world human population had nothing to do with an increase in births, but rather with a higher life span. In this article, Sol Minoldo discusses real-life examples that highlight the underlying complexity of the attempts to keep this population replacement rate constant.

La máquina de hacer pastillas - The pill-making machine

Pharmaceutical companies do not set their prices based on production costs, but rather based on market price. In courtiers under development, this frequently limits the access of pharmaceutical products to people that need them but cannot afford it. Price mainly depends on the relationship between supply and demand, competition with other suppliers, and the level of 'freedom' with which pharmaceutical companies can operate. In the present article, Julieta Alcain, Nicolas Chiarante, and Matías Zelaya discuss in detail each of these variables, and how public production of medicines may secure their supply to every patient that may need them.

Neuroeducational Intervention in Children with Intellectual Disabilities - Intervención Neuroeducativa en Niños con Discapacidad Intelectual

Silvia Gonzalez, Yessica Milena Flórez Bautista, Monica Machado sanchez

Languages: Spanish, Castilian

DOI: 10.17160/josha.8.5.792

An adequate intervention in the classroom for children with intellectual disabilities has been one of the main concerns of the teaching team, due to the high dropout rate that is currently occurring in Colombia (MEN, 2015). The lack of knowledge on how to intervene is one of the most influential reasons for children in condition of intellectual disability to fail to integrate successfully, nor to achieve an optimal learning process, these factors generate frustration not only in the student, but in teachers and family members, (Martínez, 2017) therefore, the need to investigate the impact caused by different strategies in the learning process in children with intellectual disability emerged. After a review of academic literature, it was found that neuroeducation provides the necessary elements that children with disabilities need so that their process in the classroom is not truncated.

More than 30 years have passed since the Hubble Space Telescope was put into orbit at 7 km per second and 500 km far from the Earth surface. After a few (not so minor) adjustments, the Hubble Telescope gathered data that has been published in more than 15,000 scientific articles. On the contrary of what was hypothesized during the late 90s, the Hubble Telescope was critical for determining that the universe is expanding, and that the expansion velocity is actually increasing. This also supported the idea of the existence of dark energy and dark matter, something that we still do not understand at all, but occupies 68 and 27% of the Universe, respectively. It is expected that the Hubble Telescope will be operational until 2030, and then replaced by the James Webb Space Telescope. The Hubble Telescope gave us the most striking images we have from our Universe so far. This is it´s story.

Representaciones Sociales sobre Violencias en la Familia de Estudiantes Universitarios - Social representations on Violence in Families of University Students

Languages: Spanish, Castilian

DOI: 10.17160/josha.8.4.777

The concept of violence is of great relevance to our society and is presented as a problem that affects young people in Colombia, encountering difficulties both for its identification and for the generation of care actions. It is not enough to establish that a person is violated, as there is the possibility of repeating the cycle of violence without generating the necessary changes to stop it in areas such as the family or in general in their environment and context. aim. Learn about the social representations of violence in the family of students at the Politécnico Grancolombiano. Method. The present work is based on mixed research methods, with a concurrent design of quantitative weight and a descriptive scope. Results. It is found that 31.1% of the population manifests different types of violence in the family, the main ones being physical, emotional, and psychological violence.

The COVID-19 pandemic has modified the routines of people with Chronic Non-Communicable Diseases (NCD), who, due to their health condition, may suffer changes in their habits and their adherence to treatment may be affected. OBJECTIVE: To identify the level of adherence to treatment and the reasons for living of people with NCDs in the midst of COVID-19 confinement. METHOD: descriptive quantitative study. A digital questionnaire was used based on the Morisky Green tests, the Reasons for Living Inventory and the Bonilla and De Reales Test. Ninety-six people participated. RESULTS: participants have enough and multiple reasons to live, present moderate risk of adherence to non-pharmacological treatment, low and medium levels of pharmacological adherence. CONCLUSIONS: Social factors associated with COVID-19 and NCD do not constitute a risk factor for suicidal ideation, but for non-adherence to treatment.

Desarrollo de microdispositivos para Análisis de Células y Biomoléculas - Microdevice Development for Analysis of Cells and Biomolecules

Languages: Spanish, Castilian

DOI: 10.17160/josha.8.4.770

In the last decade, microfluidic devices have played an important role in many biological, chemical, and engineering applications. With this premise, in this work, microfluidic devices have been successfully developed for the optical sensing of cells with a solid-state immersed micropore chemically manufactured. In addition, cell death was assessed with chemotherapeutic drugs through fluorescence labeling of cell biomolecules to identify types of cell death. It is noteworthy that in this thesis a method of microfluidic device manufacturing was developed. This methodology does not need access to a cleanroom facility. In such a way, it is possible to integrate microfluidics in any laboratory. Several microfluidic device designs were fabricated and investigated to evaluate the ability of epoxy resin to replicate microstructures and to transfer them to polydimethylsiloxane (PDMS) for assembling microfluidic devices.

Languages: Spanish, Castilian

DOI: 10.17160/josha.8.3.765

Lockdown measures to fight the COVID-19 pandemic led to a secondary improvement in the air quality of major cities worldwide. Decreased mobility and slowing down of industrial and economic activity explain most of this effect. Unfortunately, when easing measures were implemented, air quality rapidly dropped to the levels observed before the lockdown. Moreover, no significant benefit has been evidenced in current Global Warming and Climate Change. In this article, originally published in El Gato y La Caja, Timoteo Marchini presents how the COVID-19 pandemic has highlighted the need of humans to establish a healthy relationship with the environment, not only for our development but for our survival.
