RESUMO: Objetivou-se avaliar a eficácia do sulfato de magnésio e cetamina em reduzir o requerimento de propofol, remifentanil e o resgate analgésico pós-operatório de gatas submetidas à ovariohisterectomia eletiva. Trinta gatas foram pré-medicadas com acepromazina (0,05 mg/kg) e morfina (0,3 mg/kg), intramuscular, e induzidas a inconsciência com propofol para intubação orotraqueal. As infusões contínuas (IC) de propofol e remifentanil foram iniciadas e os animais foram aleatoriamente alocados em três grupos: grupo sulfato de magnésio (MG) que recebeu bolus (50 mg/kg) e IC (80 mg/kg) de sulfato de magnésio; grupo cetamina (KG) que recebeu bolus (0,5 mg/kg) e IC (1,8 mg/kg/h) de cetamina; grupo controle (CG) que recebeu bolus e IC de solução salina 0,9%. As funções cardiovasculares e respiratórias, o tempo de extubação e a pontuação de resgate pós-operatório foram registrados e descritos com nível de significância de 95% (P < 0.05). O tempo de infusão dos tratamentos foi de 21,5 ± 3,4 e 21,0 ± 2,4 minutos no KG e MG, respectivamente (P = 0.194). As taxas de infusões de remifentanil (P = 0.336) e propofol (P = 0.716) foram similares entre grupos. Na análise de dor pós-operatória as escalas não demonstraram diferenças entre grupos quanto a número de resgates, pontuação de resgate ou tempo para o primeiro resgate. Em conclusão, os protocolos propostos foram seguros e efetivos. Contudo, o sulfato de magnésio e cetamina não demonstraram analgesia pós-operatória adicional ou efeitos adjuvantes anestésicos significativos.

ABSTRACT: This study assessed the efficacy of magnesium sulfate and ketamine hydrochloride in reducing the demand for propofol, remifentanil, and postoperative rescue analgesia in cats undergoing elective ovariohysterectomy. Thirty cats were premedicated with acepromazine (0.05 mg/kg) and morphine (0.3 mg/kg) intramuscularly and induced to unconsciousness with propofol for orotracheal intubation. The continuous infusion (CI) of propofol and remifentanil were started and animals and were randomly allocated into three groups: the magnesium sulfate group (MG) received one bolus (50 mg/kg) and CI (80 mg/kg/h) of magnesium sulfate; the ketamine group (KG) received bolus (0.5 mg/kg) and CI (1.8 mg/kg/h) of ketamine hydrochloride; the control group (CG) received bolus and CI of 0.9% saline solution. Cardiovascular and respiratory functions, extubation time, and rescue postoperative scores were assessed and data were described with a significance level of 95% (P < 0.05). The infusion period of treatments was 21.5 ± 3.4 and 21.0 ± 2.4 minutes in the KG and MG, respectively (P = 0.194). The infusion rates of remifentanil (P = 0.336) and propofol (P = 0.716) were similar between groups. Analysis of the postoperative pain scales revealed no significant intergroup differences in rescue frequency, rescue score, and time to the first rescue analgesia. In conclusion, the proposed protocols were safe and effective, yet it is noteworthy that both magnesium sulfate and ketamine failed to demonstrate significant additional postoperative analgesic or adjuvant anesthetic effects.

Abstract Purpose: To analyze diabetes mellitus (DM) in a multifactorial manner with the consumption of sugar-sweetened beverages (SSB) and variables like nutritional status, sex, genetic predisposition, age and ethnicity; in order to determine the relationship between BGA and DM in the Mazahua Otomí (MO) community. Methodological design: This quantitative survey on social and nutritional variables was designed, validated and applied. A logistic model was developed to find the relationship of DM in relation to the variables: SSB consumption, sex, genetic predisposition, age, body mass index and ethnicity. Results: The Mazahua otomi community has a monthly family income below the extreme poverty line; they do not have disease control: 68% are obese or overweight and SSB consumption is medium to high in 90% of the population. In a multifactorial manner and according to the model, there is a probability of manifesting DM depending on the variables mentioned above; while, with the exception of nutritional status and age, the others are the most significant. In taste and preferences, 52% opt for the Coca-Cola SSB brand. Research limitations: The results found should be complemented in other case studies in communities with similar characteristics and a broader probabilistic population sample. Finding: In the MO community there is a relationship between BGA consumption and DM and there is no control of the disease. This work contributes to the design of public policies to prevent health damage because of excessive consumption of SSB and its relationship with DM; likewise, those policies that rescue and promote good nutritional practices of the communities of indigenous peoples.

Resumen: Con la crisis del petróleo de principios de la década del 70, vimos el inicio del fin de los "años dorados" del modelo burocrático, en la década siguiente el modelo ya estaba ampliamente desacreditado hasta el punto del modelo de reemplazo, Nueva Gestión Pública. (NGP), siendo visto como superior. Sin embargo, los académicos señalan que la NGP no es más que "creencias precientíficas" y Denhardt y Denhardt (2000) proponen el nuevo servicio público que, entre otros aspectos, tiene como objetivo superar el individualismo y el economicismo subyacentes a la NGP. Sin embargo, los supuestos del Nuevo Servicio Público se acercan a los que ha defendido Ubuntu. Por tanto, la pregunta es: qué es Ubuntu, cuáles son los presupuestos del nuevo servicio público y cuáles son sus puntos de convergencia. Basado en una metodología que combina una visión subjetivista y una epistemología del poscolonialismo, este estudio de caso de investigación cualitativa se basó técnicamente en la revisión de la literatura y el análisis del discurso. Se concluyó que las propuestas del nuevo servicio público convergen con los cimientos de Ubuntu y que, a pesar de ser epistemologías construidas en distintos lados de las fronteras, pueden dialogar y complementarse.

Abstract: With the oil crisis at the beginning of the 70s, we saw the beginning of the end of the "golden years" of the bureaucratic model, in the following decade the model was already largely discredited, therefore, material and intellectual conditions led us to believe in and defend the superiority of the substitute model, New Public Management (NPM). However, scholars point out that NPM is nothing more than "pre-scientific beliefs" and Denhardt and Denhardt (2000) proposed the New Public Service (NPS) model which, among other aspects, aims to overcome the individualism and economism underlying NPM. However, the assumptions that shape the New Public Service propose the rescue of values that have been defended by Ubuntu for decades. The question is: what is Ubuntu, what are the assumptions of the new public service and what are its points of convergence. In ontological terms, this study adopts a subjectivist view and, epistemologically, it is anchored in post-colonialism. This is a case study associated with qualitative research that was technically based on literature review and discourse analysis. It was concluded that the proposals for the new public service converge with the foundations of Ubuntu and that, despite being epistemologies built on different sides of the borders, they can dialogue and complement each other.

Resumo: Com a crise do petróleo no início da década de 1970, assistiu-se ao princípio do fim dos "anos dourados" do modelo burocrático. Na década seguinte, o modelo já estava amplamente desacreditado; por conseguinte, condições materiais e intelectuais levaram a crer e defender a superioridade do modelo substituto, a Nova Gestão Pública (NGP). No entanto, estudiosos apontam que a NGP não passa de "crenças pré-científicas", e Denhardt e Denhardt (2000) propuseram o modelo do Novo Serviço Público (NSP) que, dentre outros aspetos, visa superar o individualismo e o economicismo subjacente à NGP. No entanto, os pressupostos que fundamentam o NSP propõem o resgate de valores que há décadas são defendidos pelo Ubuntu. Questiona-se: o que é Ubuntu, quais são os pressuposto do Novo Serviço Público e quais são os seus pontos de convergência. Em termos ontológicos, este estudo adopta uma visão subjetivista e, epistemologicamente, ancora-se no pós-colonialismo. Este é um estudo de caso associado à pesquisa qualitativa que tecnicamente alicerçou-se na revisão da literatura e análise de discurso. Concluiu-se que as propostas do Novo Serviço Público convergem com os fundamentos do Ubuntu e que, a despeito de serem epistemologias construídas em lados diferentes das fronteiras, podem dialogar e se complementar.

Abstract Introduction: Despite sensory enrichment being critical for ensuring the well-being of captive wild animals, smells are not being included in enrichment protocols for birds. For this group, neophobia can be a problem when it comes to implementing new enrichment devices. Objective: To explore how participation in an olfactory enrichment and latency times varies between bird taxonomic groups (Amazona spp. / Ara spp. / Ramphastos spp.). Methods: We exposed 257 birds to a scent enrichment, and we recorded which individuals engaged with it and the time they took to interact with it. Results: We discovered that participation by toucans in the enrichment was higher compared to amazons and macaws. Furthermore, latency time to interact with the enrichment was higher in amazons that in the other species. Our findings could suggest that toucans are neophilic species which could benefit from higher exploration rates. Amazons on the contrary seem to be particularly neophobic, possibly because of their less opportunistic feeding habits compared to toucans and their higher vulnerability to predation compared to macaws. Conclusion: These results point out that toucans would be more inclined to engage in environmental enrichments, while a more natural design using smells inside familiar objects could be a more successful enrichment for psittacids.

Resumen Introducción: A pesar de que el enriquecimiento sensorial es fundamental para garantizar el bienestar de los animales silvestres en cautiverio, los olores no son incluidos de forma rutinaria en los protocolos de enriquecimiento para aves. Además, en el caso de estos animales, la neofobia puede ser un problema a la hora de implementar nuevos dispositivos de enriquecimiento. Objetivo: Explorar cómo varía la participación y la latencia en la interacción con un enriquecimiento olfativo entre grupos taxonómicos de aves (Amazona spp. / Ara spp. / Ramphastos spp.). Métodos: Expusimos a 257 aves a un enriquecimiento olfativo y registramos qué individuos participaron y el tiempo que tardaron en interactuar con él. Resultados: La participación en el enriquecimiento fue mayor en los tucanes en comparación con las amazonas y los guacamayos. Además, el tiempo de latencia para interactuar con el enriquecimiento fue mayor en las amazonas que en las otras especies. Nuestros hallazgos sugieren que los tucanes son especies neofílicas que podrían beneficiarse de tasas de exploración más altas. Por otro lado, las amazonas parecen ser particularmente neofóbicas, posiblemente debido a sus hábitos alimenticios menos oportunistas en comparación con los tucanes y a su mayor vulnerabilidad a la depredación en comparación con los guacamayos. Conclusión: Estos resultados señalan que los tucanes serían más proclives a participar en enriquecimientos ambientales, mientras que un diseño que utilice olores dentro de objetos más naturales o familiares podría ser más exitoso para las psitácidas.

Abstract Objective To compare the effectiveness of inhaled Magnesium Sulfate associated with Salbutamol versus Inhaled Salbutamol alone in patients with moderate and severe asthma exacerbations. Method Clinical, prospective and randomized study with patients between 3 and 14 years of age divided into two groups: one to receive inhaled salbutamol associated with magnesium sulfate (GSM), the other to receive inhaled salbutamol alone (GS). The sample consisted of 40 patients, 20 patients in each group. Severity was classified using the modified Wood-Downes score, with values between 4 and 7 classified as moderate and 8 or more classified as severe. Results Post-inhalation scores decreased both in patients who received salbutamol and magnesium and in those who received salbutamol alone, with no statistically significant difference between the groups. Conclusions Despite the benefits when administered intravenously, inhalation of the drug alone or in combination did not reduce the severity of the exacerbation. exacerbations Clinical 1 groups GSM, GSM , (GSM) GS.

Abstract From a feminist perspective, we present the possibilities and limits of a qualitative research technique that considers the active participation of people who articulate with the researcher under a critical perspective and with a rescue of their embodied emotional experience, such as the construction of Life Narratives. This feminist method challenges the traditional ways of generating qualitative knowledge by promoting a horizontal relationship between the researcher and the participant and aims to confront the questioned academic extractivism present in contemporary universities. In this case, four Life Narratives were generated with female academics who are or were directors of PhDs in Chilean universities and who led the quality assurance process of their programmes. The limits are presented both technically and also with regard to the effective possibilities of moving traditional structures in the form of knowledge production. Furthermore, although this technique seeks to address feminist criticisms related to leaving corporeality and emotionality out of the research, this incorporation is not always achieved with participants in positions of power. It is concluded that this method allows a critical reflexivity typical of feminist work, unravels the power dynamics present in the processes of knowledge construction and also allows us to see the consequences that research practices have both on the subjects involved and on their contexts.

Resúmen A partir de una perspectiva feminista, se presentan las posibilidades y límites de una técnica de investigación cualitativa que considera la participación activa de las personas que se articulan con la investigadora bajo una perspectiva crítica y con un rescate de su experiencia emocional corporeizada, como es la construcción de Narrativas de Vida. Este método feminista desafía las tradicionales maneras de generación de conocimiento cualitativo al promover una relación horizontal entre la persona investigadora y participante, y pretende hacer frente al cuestionado extractivismo académico, presente en la universidad contemporánea. En este caso, se generaron cuatro Narrativas de Vida con académicas que son o fueron directoras de programas de doctorado en universidades chilenas y que lideraron el proceso de aseguramiento de la calidad de sus programas. Se presentan los límites tanto técnicos como también respecto de las posibilidades efectivas de mover las estructuras tradicionales en la forma de producción de conocimiento. Asimismo, si bien esta técnica busca hacer frente a las críticas feministas relacionadas con el hecho de dejar la corporalidad y emocionalidad fuera de la investigación, no siempre esta incorporación es lograda con personas participantes ubicadas en posiciones de poder. Se concluye que este método permite una reflexividad critica propia de los trabajos feministas, permite desentrañar las dinámicas de poder presentes en los procesos de construcción del saber y además permite ver las consecuencias que las prácticas de investigación tienen tanto en los sujetos implicados como en sus contextos.

Resumo O quadro legal que serve de base à perseguição da homossexualidade em Portugal e no Estado espanhol surge antes do início das ditaduras ibéricas. Em Portugal, por exemplo, a I República cria legislação contra “os que praticam vícios contra a natureza”, a partir da Lei da Mendicidade (1912). No caso espanhol, o Código Penal de 1870 introduz, pela primeira vez, as categorias de delitos sexuais, que são usados para a detenção de homossexuais até à chegada da democracia. Apesar da homo/lesbofobia ser anterior aos regimes fascistas, é neste tipo de regimes que a perseguição da homossexualidade se transforma num elemento chave. Estas e outras leis, a aplicar mais tarde pelo Estado Novo e pelo franquismo, levam a que a homossexualidade seja observada enquanto crime. As comparações efetuadas pretendem reforçar a necessidade de continuar a resgatar a memória LGBTI, em particular na Península Ibérica. Assim, este artigo pretende analisar e comparar a legislação aplicada a homossexuais nos dois países, desde o século XIX, com o surgimento dos primeiros Códigos Penais, até à descriminalização da homossexualidade, que tem lugar em meados dos anos 80 do século XX.

Abstract The legal framework that underpins the persecution of homosexuality in Portugal and in the Spanish State appears before the beginning of the Iberian dictatorships. In Portugal, for example, the I Republic creates legislation against “those who practice vices against nature”, based on the Lei da Mendicidade (1912). In the Spanish case, the Penal Code of 1870 introduces, for the first time, the categories of sexual crimes, which are used for the detention of homosexuals until de arrival of democracy. Although homo/lesbophobia pre-dates fascist regimes, it is in these types of regimes that the persecution of homosexuality becomes a key element. These and other laws, to be applied later by the Estado Novo and Francoism, lead to homosexual being observed as a crime. The comparisons made intend to reinforce the need to continue to rescue the LGBTI memory, particularly in the Iberian Peninsula. This article aims to analyse and compare the legislation applied to homosexuals in both countries, from 19thcentury, with the emergence of the first Penal Codes until the decriminalization of homosexuality, which took place in the mid-1980’s.

Abstract: High-frequency oscillatory ventilation with volume guarantee (HFOV-VG) is a ventilatory mode that controls small tidal volumes at supraphysiological frequencies, potentially beneficial for preterm infants with respiratory distress syndrome (RDS). Objective: To identify the physiological and clinical effects of HFOV-VG in preterm newborns with RDS, compared with conventional HFOV. Method: Exploratory review of studies published between 2019 and 2023 of preterm newborns from 23 to 36 weeks of gestation with RDS, weighing ≥ 450g, with invasive HFOV support, using PRISMA flow diagram. For their critical evaluation, the MINORS and PEDro scales were used. Results: 1,386 articles were initially identified, of which 7 articles were selected. Compared with conventional HFOV, the use of lower tidal volumes (VThf) and higher respiratory rate stands out, as well as better and more stable gas exchange, both as an elective or early rescue strategy in preterm newborns with RDS. Furthermore, an inverse relationship is observed between VThf and respiratory rate. Conclusion: HFOV-VG, used in preterm neonates with RDS, consistently improves oxygenation and ventilation compared with conventional HFOV. Control and reduction of VThf could provide additional lung protection.

Resumen: La ventilación de alta frecuencia (VAF) con volumen garantizado es un modo ventilatorio que controla pequeños volúmenes corriente a frecuencias suprafisiológicas, potencialmente beneficioso para prematuros con síndrome de dificultad respiratoria (SDR). Objetivo: Identificar los efectos fisiológicos y clínicos de la VAF con volumen garantizado en recién nacidos pretérmino con SDR, en comparación con VAF convencional. Método: Revisión exploratoria de estudios publicados entre 2019 y 2023, de recién nacidos prematuros de 23 a 36 semanas de gestación con SDR, con un peso ≥ 450 g soportados con VAF invasiva, utilizando diagrama de flujo PRISMA. Para su evaluación crítica se utilizaron las escalas MINORS y PEDro. Resultados: Se identificaron inicialmente 1,386 artículos, de los cuales se seleccionaron 7 artículos. En comparación con VAF convencional destaca el uso de menores volúmenes corriente (VThf) y mayores frecuencias respiratorias, un intercambio de gases mejor y más estable, tanto como estrategia electiva o de rescate temprano en recién nacidos prematuros con SDR. Además se observa una relación inversa entre VThf y frecuencia respiratoria. Conclusión: La VAF con volumen garantizado, aplicada en recién nacidos prematuros con SDR, consistentemente mejora la oxigenación y ventilación en comparación con la VAF convencional. El control y la reducción de VThf pudiera proporcionar una protección pulmonar adicional.

ABSTRACT: It aimed to compare the trans anesthetic clinical and perioperative analgesic effects by prolonged continuous infusion of fentanyl (GF, bolus of 5 µg/kg and continuous infusion (CI) of 15 µg/kg/h) or remifentanil (GR, CI of 18 µg/kg/h) in dogs undergoing to elective ovariohysterectomy. Twenty female healthy dogs were premedicated with acepromazine, inducted to unconsciousness with propofol and kept under anesthesia with isoflurane. The M0 (baseline) was recorded and animals were randomly allocated in GF (n = 10) or GR (n = 10), recording clinical and blood gas parameters every 15 minutes (M15…M120) for two hours and, after, during surgery, adjusting the opioid rate according to surgical requirement. The isoflurane vaporization reduced by up to 47% and 42% in GF and GR, respectively, when compared to M0. During the first two hours of CI, six animals of each group required atropine intervention and three animals of GF required ephedrine. The number of rate adjustments during intraoperative was significant higher in GR when compared to GF (P = 0.0248). By the Log-rank test, there was a higher possibility of not receiving analgesic rescue in the first 30 minutes of postoperative in GF when compared to GR (P < 0.0001) and all animals required analgesic rescue during the firsts 3 and 6 hours in GR and GF, respectively. It is concluded that, when the proposal continuous infusions were compared, fentanyl required fewer analgesic rescues during perioperative, nonetheless, it is recommended rate adjustment during intraoperative and additional analgesia for postoperative for both treatments.

RESUMO: Objetivou-se comparar os efeitos clínicos intraoperatórios e analgésico perioperatório ofertados pela infusão contínua prolongada de fentanil (GF, bolus de 5 µg/kg e infusão contínua (IC) de 15 µg/kg/h) ou remifentanil (GR, IC de 18 µg/kg/h) em cadelas submetidas a ovariohisterectomia eletiva. Vinte cadelas hígidas foram pré-medicadas com acepromazina e induzidas com propofol e mantidas sob anestesia com isoflurano. Registrado M0 (basal) os animais foram alocados aleatoriamente em GF (n = 10) ou GR (n = 10), registrando parâmetros clínicos e hemogasométricos a cada 15 minutos (M15...M120), totalizando 02h e, posteriormente, durante o procedimento cirúrgico, sendo a taxa do opioide alterada conforme o requerimento cirúrgico.A vaporização de isoflurano reduziu em até 47% e 42% no GF e GR, respectivamente, em relação ao M0. Durante as primeiras duas horas de IC, seis animais de cada grupo necessitaram de intervenção com atropina e três animais do GF de efedrina. O número de ajustes de taxas no intraoperatório foi significativamente maior no GR comparado ao GF (P = 0,0248). Pelo teste de Log-rank, houve maior probabilidade de não receber resgate analgésico nos primeiros 30 minutos de pós-operatório no GF comparado ao GR (P < 0,0001) e todos os animais necessitaram de resgate analgésico dentro das primeiras três e seis horas no GR e GF, respectivamente. Conclui-se que, nas taxas propostas, a utilização de fentanil necessitou de menos resgates analgésicos no intra e pós-operatório, no entanto, recomenda-se ajuste de taxa intraoperatória e analgesia suplementar pós-operatória em ambos os tratamentos.

Resumo A geografia humana desempenha um papel fundamental na adaptação das comunidades ao meio ambiente ao longo do tempo. Ela considera aspectos como a modificação do território, a organização social e as atividades econômicas como o turismo cultural que aborda a geografia, a história e a cultura, valorizando os conhecimentos e processos das comunidades. Portanto, o presente artigo propõe um projeto para criar um Ecomuseu da cultura Chorotega na comunidade de Matambú, localizada na Unidade de Planejamento Turístico Guanacaste Sul, na Costa Rica. A proposta surge como resposta a uma necessidade da comunidade indígena de se envolver no turismo para subsistir, com o objetivo de fomentar o ecoturismo, turismo cultural e criativo no Território Indígena Chorotega Matambú (TICM) e contribuir para a melhoria das condições socioeconômicas da comunidade indígena, preservando e resgatando o senso de pertencimento do patrimônio cultural e natural por parte dos habitantes do território. Após alcançar o objetivo de criar o Ecomuseu “Los Chorotegas” na comunidade de Matambú, haverá uma melhoria na qualidade de vida. Simultaneamente, a comunidade será mais respeitada e reconhecida como a única etnia de origem Mesoamericana presente na Costa Rica.

Abstract Over time, human geography has played a fundamental role in communities’ processes of adaptation to their environment. This involves considerations spanning the modification of territories, social organization, and economic activities such as cultural tourism. This also involves understanding the geographic context of their history and culture to add value to communities’ knowledge and processes. Therefore, this article proposes the creation of a Chorotega Culture Eco-Museum in Matambú, a community located within the South Guanacaste Unit of Touristic Planning, Costa Rica. This proposal arises from the necessity of this indigenous community to be part of the tourism industry as a survival strategy. The objective is to promote ecotourism and cultural and creative tourism in the Matambú Chorotega Indigenous Territory (TICM). This initiative serves as a method to enhance the socio-economic conditions of the indigenous community while helping to preserve and rescue the sense of belonging to its cultural and natural heritage. By achieving the objective of creating “Los Chorotegas” Eco-Museum in the Matambú community, this territory and indigenous group will be respected and valued as the only remaining ethnicity of Mesoamerican origin within Costa Rica, and this recognition can improve their quality of life.

Resumen La geografía humana desempeña un papel fundamental en la adaptación de las comunidades al medio ambiente a lo largo del tiempo, considerando aspectos como la modificación del territorio, organización social, actividades económicas como el turismo cultural que aborda el contexto geográfico, historia y cultura poniendo en valor los saberes y procesos de las comunidades. Por lo tanto, el presente artículo plantea una propuesta para diseñar un Ecomuseo de la cultura Chorotega en la comunidad de Matambú ubicada en la Unidad de Planeamiento Turístico Guanacaste Sur en Costa Rica. La propuesta surge en respuesta a una necesidad de la comunidad indígena de involucrarse en el turismo para subsistir, con el objetivo de fomentar el ecoturismo, turismo cultural y creativo en el Territorio Indígena Chorotega Matambú (TICM) y contribuir al mejoramiento de las condiciones socioeconómicas de la comunidad indígena, conservando y rescatando el sentido de pertenencia del patrimonio cultural y natural por parte de los habitantes del territorio. Cumplido el objetivo de crear el Ecomuseo “Los Chorotegas” en la comunidad de Matambú, mejorará la calidad de vida y a la vez serán más respetados, visibilizados como la única etnia de origen Mesoamericana presente en Costa Rica.

Abstract: This essay shows a historical alternative that the United Railways of Yucatan could travel. It presents the reorganization project of 1942 analyzing circumstances, actors and expectations that fed it. For this purpose, two sections are developed that frame and precede said alternative; in them it realizes, among other points, the origins of the company, the tensions that gave birth to it, the first effects that the revolution imposed on it and that continued to overwhelm it, its dependence on the predominance of henequen, the fragility of its finances, the onerous weight of their “english debt” and the various subnational and federal efforts to revitalize them. The last section studies the financial basis of the private project of 1942 that sought to revive them and, for reasons that are clarified, did not prosper. It goes without saying that it seems pertinent to rescue this forgotten experience now that the new Mayan train takes effect.

Resumen: Este ensayo muestra una alternativa histórica que pudieron recorrer los Ferrocarriles Unidos de Yucatán. Presenta el proyecto reorganizativo de 1942 analizando circunstancias, actores y expectativas que lo alimentaron. Para tal fin se desarrollan dos apartados que enmarcan y preceden a esa alternativa; en ellos se da cuenta, entre otros puntos, de los orígenes de la empresa, las tensiones que la alumbraron, los primeros efectos que le impuso la revolución y que continuaron agobiándola, su dependencia respecto a la predominancia del henequén, la fragilidad de sus finanzas, el oneroso peso de su “deuda inglesa” y los diversos esfuerzos estatales y federales para revitalizarlos. El último apartado estudia la base financiera del proyecto privado de 1942 que pretendía revivirlos y, que por razones que se aclaran, no prosperó. Huelga observar que parece pertinente rescatar esta experiencia olvidada ahora que cobra vigencia el nuevo tren maya.

The use of YouTube videos in learning English language has produced disruptive or alternative innovations for students learning anywhere in the world. YouTube English language learning videos have been dominated by content-driven and outcomes-driven curriculum approaches at the expense of a self-driven approach. The purpose of this study was to explore the YouTube video approaches used by students in the learning of English language in higher education in selected African countries. The study also sought to establish why students use YouTube approaches in learning English language in particular ways. Undergirded by the pragmatic paradigm and the mixed method approach, the study employed the use of the natural identity framework (NIF). A participatory action research with one-on-one semi-structured interviews, focus group discussions, document reviews and YouTube reviews/observations were applied in collecting data from 20 purposively and snowball sampled participants (English language students) to be thematically analysed for this study. The findings indicate that the dominance of these two approaches has produced tension between them that needs to be addressed by a self-driven approach which is capable of creating a space for self-reflection before learning processes take place. It is for this tension that this study explores YouTube video approaches used in the learning of English language in higher education in Africa post the COVID-19 pandemic. A self-driven approach concentrates on actions, beliefs behind the actions, and their outcomes of using YouTube videos. This study therefore recommends the application of a self-driven approach and awareness of natural forces/laws that promote natural actions, thus addressing personal, and natural needs.
