Recognising the human in humanities [Australian Review of Applied Linguistics]
Authors: Oliver Rhonda , Dovchin Sender
Published: December 2024

In this essay we reflect upon Wolfgang Klein’s 1989 paper Schreiben oder Lesen, aber nicht beides, oder: Vorschlag zur Wiedereinführung der Keilschrift mittels Hammer und Meißel (Zeitschrift für Literaturwissenschaft und Linguistik 74. 116–119) about the exponential development of knowledge and the imbalance between the production and reception of this. Whilst appreciating the sentiment, we argue against what seems to be his underestimation of the contribution of humanities. Klein suggests those in our field are content because unlike natural scientists, we “do not harm”: We contend we do much more – supporting and enhancing the lives of humankind. When addressing the question of “why do we do what we do?”, we answer by saying humanities and specifically applied linguistic researchers make a difference. We strive to understand the linguistic landscape, and to heighten awareness and understanding about culture, language, language learning and communication. Those working in the field advocate for and support those who are marginalised and lack agency, giving voice to those who are often silenced.
The economic reterritorialization of academic publishing and the politics of reading [Journal of Sociolinguistics]
Authors: Pietikäinen Sari , Zavala Virginia
Published: December 2024

Using Klein’s observation of almost 35 years ago of the disturbed balance between production and reception of academic knowledge as a starting point, we reflect on some of the tensions related to current reading practices in academic publishing. Specifically, we discuss two tensions that we encounter and try to resolve in our role as editors: 1) the tension between standardization and creativity, and 2) the tension between monologue and dialogue. Throughout, we also discuss a third more general tension, namely the gap between academic values of knowledge production embedded in the collegial work for scientific publications, and the profit driven publishing industry.
Exploring pre-service foreign language teachers’ intention to adopt technology: an investigation from the perspective of Situated Expectancy-Value Theory
Authors: Li Siying
Published: December 2024

The intention of pre-service foreign language teachers to adopt technology (PIAT) reflects their willingness to integrate educational technology tools into their teaching practices, which is essential for the digital transformation of language education and the professional development of teacher candidates. Drawing upon the Situated Expectancy-Value Theory, this study utilizes a structural equation model to analyze the factors influencing the intention of pre-service foreign language teachers to adopt technology. The results reveal that: (1) four motivational factors (i.e., self-efficacy, perceived enjoyment, perceived importance, and perceived usefulness) significantly predict PIAT, while perceived anxiety negatively correlates with, but does not significantly predict PIAT; (2) mindset significantly impacts perceived enjoyment, perceived importance, perceived usefulness, and perceived anxiety; (3) social influence exerts a significant influence on self-efficacy and mindset. The study concludes with implications for enhancing the digital literacy of foreign language teacher candidates.
Enhancing advanced vocabulary in EFL writing: an AI-assisted intervention for English studies students in Poland
Authors: Pitura Joanna
Published: December 2024

Effective use of advanced vocabulary is crucial for higher-level English language learners, particularly as they progress towards C1 proficiency according to the Common European Framework of Reference for Languages (CEFR). However, incorporating sufficiently sophisticated vocabulary in writing remains challenging for many learners. This quasi-experimental study investigated the effectiveness of an AI-assisted intervention designed to enhance awareness and use of advanced vocabulary among B2 level first-year English Studies students in Poland (n = 71). The intervention, integrated into regular coursework over five sessions, included exposure to advanced vocabulary through reading, explicit instruction on word proficiency levels, and opportunities for vocabulary use in writing. Data were collected through summary writing and word recognition tasks. The CEFR checker, an AI-based text analyser, was employed to identify C1+ and B2 level vocabulary in students’ writing. Results revealed modest but noticeable improvements in both the use and recognition of C1+ and B2 level vocabulary over time. The study also found changing correlations between vocabulary use and recognition across sessions, particularly for C1+ words. These findings highlight the potential of AI-assisted instruction in enhancing advanced vocabulary among higher proficiency EFL learners. The study contributes to the growing body of CALL literature on AI-assisted L2 instruction and opens avenues for further research on new pedagogical approaches to facilitate advanced vocabulary development in EFL writing.
Thinking the Pure and Empty Form of Dead Time. Individuation and Creation of Thinking in Gilles Deleuze’s Philosophy of Time
Authors: Eftestøl Torbjørn
Published: December 2024

In his account of the individuation and creation of thinking in Difference and Repetition Gilles Deleuze claims that there belongs “an experience of death.” What does this mean and imply for an attempt to come to terms with Deleuze’s transcendental empiricism? The following article presents a reading that explores this question, arguing that Deleuze’s account of what it means to think has two aspects that must be understood in relation to each other. On the one hand, Deleuze’s ontology of intensive difference involves an image of human individuation grounded upon a “death present in the living.” On the other hand, Deleuze writes that in the creation of “thinking in thought” there is an experience of death. Understanding the relation between the individuating aspect of death – as the emergence of the pure and empty form of time as the basis for representational thinking and judgement – and the experience of this individuating factor in the creation of thinking in thought, Deleuze’s claim can be made sense of and its centrality in his system clarified. When death as an individuating factor becomes experience, thinking is transmuted from dead representation to intensive life, and transcendental empiricism is operationalized.
Effect of incorporating ultrafine palm oil fuel ash on the resistance to corrosion of steel bars embedded in high-strength green concrete
Authors: Magbool Hassan M. , Zeyad Abdullah M. , Aksaraei Aliakbar Mahmoudi Kouch , Johari Megat Azmi Megat
Published: December 2024

Durability degradation in reinforced concrete (RC) constructions is commonly attributed to the steel reinforcement corrosion caused by chloride. The utilization of supplemental cementitious resources, such as waste materials from industrial and agricultural sectors, typically improves the impermeability and strengthens concrete resistance to corrosion, sulfate, and acid attacks. Therefore, the prevention of steel reinforcement corrosion is greatly important in resolving challenges related to the durability and stability of RC structures, particularly when utilizing agriculture waste materials. This approach also serves as a solution for waste disposal. The aim of this study is to investigate the corrosion-resistant characteristics of high-strength concrete that contains ultrafine palm oil fuel ash (U-POFA) as a partial replacement for cement. Four high-strength green concrete (HSGC) mixes were investigated in this study with a partial replacement of ordinary Portland cement (OPC) by U-POFA at 0, 20, 40, and 60% by mass. The aim of this study is to analyze the workability, strength activity index (SAI), compressive strength, rapid chloride permeability, linear polarization resistance (LPR) by different measurement methods, and four-probe resistivity measurement by electrical resistivity measurement method of over a curing period of 7, 28, 60, and 90 days. The use of U-POFA in the different mixes results in improved workability, SAI, compression strength, and chloride penetration resistance compared with the zero-POFA mix. It is clear from the study results that adding U-POFA as a partial replacement for OPC improved the corrosion resistance of HSGC mixtures. Thus, the incorporation of U-POFA 60% succeeded in reducing the chloride ion penetration by 80% and the LPR by 93% at the test age of 90 days, compared to the reference mixture.

TENSIONES EN LA DEMOCRATIZACIÓN ESCOLAR
Authors: Giovine Renata , Cuchan Natalia
Published: December 2024

El artículo analiza las tensiones que subyacen en el proceso de democratización de los vínculos escolares, a partir del abordaje interpretativo de documentos normativos del nivel nacional y provincial, dado el carácter federal del Sistema Educativo Argentino. La centralidad que asume el nivel federal a partir de la Ley Federal de Educación en los años ‘90 permite observar marchas y contramarchas en los intentos de legislar y regular los vínculos escolares, en un contexto de cuestionamiento a la relación adultocéntrica y de incorporación de nuevos discursos sobre las juventudes, la política y la educación. En particular, se analizan las tensiones expresadas en el pasaje del modelo disciplinar tradicional hacia la apelación de los sistemas de convivencia en la escuela secundaria argentina.

Abordar Juventude e escola de forma relacional é um desafio que se impõe quando pensamos políticas educacionais para o ensino médio. Relação bastante complexa que na sua análise envolve múltiplos olhares e referenciais teóricos que evidenciam as tensões e desafios existentes na relação atual entre juventude e escola. Ao mesmo tempo, uma condição juvenil no Brasil particular que se expressa na sua diversidade e na sua identidade de jovem trabalhador. Refletir sobre essa relação implica reconhecer o jovem como sujeito social e a escola, como uma instituição cultural e que seu reconhecimento como direito a ser garantido aos jovens brasileiros é bastante recente. Os jovens são, nesse sentido, sujeitos históricos, diversos em suas experiências, constituídos de distintas identidades, produtos e produtores de seu tempo e espaço, determinantes e determinados pela realidade que vivenciam. A fase juvenil, para além de uma definição cronológica, é um processo complexo estabelecido pela própria existência, não se restringindo a uma etapa intermediária entre a infância e a idade adulta. Compreender a noção de “juventudes”, no plural, significa evidenciar a ideia de que não existe apenas “uma juventude”, mas sim diversos “modos de ser jovem”, diferentes juventudes, diversidades da condição juvenil, formas de vida plural que se materializa nos distintos espaços que vivem. O ensino médio é uma etapa da educação básica que historicamente carrega vários projetos diferentes, e as vezes até antagônicos, de País e de formação humana para nossos jovens. É o caso da reforma do ensino médio materializada na Lei nº 13.415, de fevereiro de 2017 e na Base Nacional do Ensino Médio na égide da economia capitalista globalizada de racionalidade neoliberal que põe em questão uma formação integral e cidadã, bem como as demandas e as realidades das juventudes brasileiras, em especial as periféricas e pobres. Temos a convicção de que pensar a relação entre juventude e ensino médio vai além dessa reforma e requer uma reflexão sobre a condição juvenil contemporânea e os desafios para a escola. O presente Dossiê tem por escopo oportunizar um espaço de socialização, discussão e divulgação das distintas pesquisas que se desenvolve no Brasil e no exterior sobre as “Juventudes e o Ensino Médio”. O Dossiê reunirá textos resultantes de pesquisas e experiências que abordem a temática enquanto objeto de estudo, teorização, problematização e indicativos de alternativas para o campo educacional.

Alcohol Modulates Frontal Cortex and BLA Network States Which Correlate with Future Voluntary Alcohol Consumption
Authors: DiLeo Alyssa , Antonodiou Pantelis , Blandino Katrina , Conlin Eli , Melón Laverne , Maguire Jamie L.
Published: December 2024

Although most adults in the United States will drink alcohol in their life, only ∼6% will go on to develop an alcohol use disorder (AUD). While a great deal of work has furthered our understanding of the cycle of addiction, it remains unclear why certain people transition to disordered drinking. Altered activity in regions implicated in AUDs, like the basolateral amygdala (BLA), has been suggested to play a role in the pathophysiology of AUDs, but how these networks contribute to alcohol misuse remains unclear. Here we investigated how the impact of alcohol on the BLA network relates to alcohol exposure. We first examined the effect of acute ethanol administration on the BLA and frontal cortical networks and the relationship with subsequent voluntary ethanol consumption using the Intermittent Access paradigm. In addition, we recorded network activity from the BLA and frontal cortex throughout the Drinking-in-the-Dark-Multiple Scheduled Access paradigm to assess the impact of voluntary alcohol consumption on network states during binge and abstinence periods. Finally, we investigated the impact of acute withdrawal from chronic alcohol exposure on BLA and frontal cortex network states using the Chronic Intermittent Ethanol (vapor) paradigm. We demonstrate that across paradigms, ethanol alters low gamma band (40–70 Hz) oscillations and remarkably correlates with the extent of future voluntary ethanol consumption in the IA paradigm. These data suggest that BLA network states play a role in the mechanisms influencing voluntary alcohol intake.

Published: December 2024

Increasing data suggest a crucial relationship between glycolipid metabolic disorder and neuropsychiatric injury. The aim of this study is to investigate the behavioral performance changes and neuropathological injuries in mice challenged with high-fat diet (HFD) and streptozotocin (STZ). The glucose metabolism indicators and behavioral performance were detected. The mRNA expression of IL-1β, IL-6, TNF-α, ocln, zo-1, and clnds and protein expression of APP, p-Tau, p-IRS1, p-AKT, p-ERK, and TREM1/2 were measured. The fluorescence intensities of MAP-2, NeuN, APP, p-Tau, GFAP, and IBA-1 were observed. The results showed that combination of HFD and STZ/I.P. could induce glucose metabolic turmoil and Alzheimer's disease (AD)-like neuropsychiatric dysfunction in mice, as indicated by the increased concentrations of fasting blood glucose and impaired learning and memory ability. Moreover, the model mice presented increased levels of APP, p-Tau, p-IRS1, TREM2, IL-1β, IL-6, TNF-α, ocln, zo-1, and clnds; decreased levels of p-AKT, p-ERK, and TREM1; and neuron damage and the hyperactivation of astrocytes and microglia in the hippocampus as compared with control mice. Only male mice were used in this study. Although AD and type 2 diabetes mellitus (T2DM) are distinct pathologies, our results suggested that combination of HFD and STZ/I.P., a widely used T2DM modeling method, could successfully induce AD-like behavioral impairments and neuropathological injuries in mice; the mechanism might be involved with neuroinflammation and its associated dysfunction of IRS1/AKT/ERK signaling pathway. Our findings further support the potential overlap between T2DM and AD pathophysiology, providing insight into the mechanisms underlying the comorbidity of these diseases.

Published: December 2024

Delay discounting (DD) is a phenomenon where individuals devalue a reward associated with a temporal delay, with the rate of devaluation being representative of impulsive-like behavior. Here, we first sought to develop and validate a mouse DD task to study brain circuits involved in DD decision-making within short developmental time windows, given widespread evidence of developmental regulation of impulse control and risk-taking. We optimized a T-maze DD task for mice that enables training and DD trials within 2 weeks. Mice learned to choose between a large and a small reward located at opposite arms of a T-maze. Once training criteria were met, mice underwent DD whereby the large reward choice was associated with a temporal delay. Task validation showed that adolescent C57BL/6J mice display an increased preference for the small reward upon a temporal delay, confirming increased impulsivity compared with adults. We next used this DD task to explore the neural basis of decision-making. We used tyrosine hydroxylase transgenic mice (TH-Cre) to target TH-positive neurons in the nucleus accumbens (NAc) and ventral tegmental area (VTA) with Cre-dependent excitatory or inhibitory designer receptors exclusively activated by designer drugs (DREADDs). Inhibition of transduced neurons in the NAc decreased preference for the small but immediate reward during DD. Inhibition of TH-positive neurons in the ventral tegmental area (VTA) did not affect impulsive choice in this DD task. These results uncover a novel role for NAc TH-positive neurons in DD behavior and expand the repertoire of behavioral tasks available for studying decision-making across the lifespan.
A rare case of bladder paraganglioma treated successfully with robotic partial cystectomy
Authors: Shekhda Kalyan M , Palan Jessal M , Albor Christo B , Wan Simon , Chung Teng-Teng
Published: December 2024

Bladder paragangliomas are rare extra-adrenal urological tumors that account for around 0.05% of bladder cancers. Their diagnosis is often delayed because of the rarity of these tumors. There is a risk of an intraoperative hypertensive crisis if not diagnosed or identified before surgical removal. We describe a case of a 36-year-old lady presented with a 10-year history of post-micturition palpitations and headaches. Her biochemical workup showed raised urinary normetanephrine levels and imaging showed a 123I MIBG-avid bladder mass compatible with bladder paraganglioma, although interestingly almost no tracer was picked up in 68Ga DOTATATE imaging. She was started on phenoxybenzamine to control her blood pressure prior to surgery. She underwent a successful robotic partial cystectomy with no complications. After surgery, she remained symptom-free. Bladder paragangliomas are rare neuroendocrine tumors of the bladder, which need to be diagnosed and managed effectively to avoid intraoperative and long-term complications.

Learning points

It is important for patients with a bladder lesion to have a comprehensive differential assessment and biochemical and radiological investigations including functional imaging.

Multiple imaging modalities along with what is available are useful in the assessment of bladder paraganglioma.

The key role of the multidisciplinary team is to plan treatment in the perioperative period for minimizing risk, especially in situations where optimal management is actively debated.

This paper presents an improved approach to the calculation and analysis of spatial distributions of local strains in synthesized diamond crystals obtained from the normalized parameters of Kikuchi patterns. This approach consists in the study of Kikuchi patterns using normalized Kikuchi band profiles and the normalized characteristics of the energy Fourier spectrum of the diffraction patterns. The spatial strain distribution for 6 samples of polycrystalline artificial diamond was studied. A cluster analysis of the investigated crystal samples was carried out, which made it possible to establish relationships between the conditions of diamond crystal growth and their strain distributions.

The effect of doping porous carbon material (PCM) with erbium, as a metal with a high density of electronic states, on the electrochemical properties of PCM was investigated. It was established that the optimal concentration of introduced erbium 0.2% leads to a significant increase in specific capacity for the devices formed on the basis of erbium-doped carbon material. And the doping of PCM with both erbium (0.2 wt.%) and copper (0.1 wt.%) results not only in the specific capacity increase but also lowers total system impedance.

Published: December 2024

При температурі збудження в процесах фосфоресценції та релаксації струму провідності приймають участь як мінімум три типи пасток (мілка, фосфоресцентна та глибока). Тому необхідно використовувати багатоцентрову модель кристалофосфору, для якої одержані теоретичні залежності інтенсивності фосфоресценції і релаксації струму провідності. Ці залежності враховують процеси повторної локалізації носіїв заряду на усі пастки. Рівень заповнення різних пасток залежить від інтенсивності збудження, а не тільки від загальної дози опромінення. Усі експериментальні залежності інтенсивності фосфоресценції і релаксації струму провідності для кристалів ZnSe (дози рентгенівського опромінення змінювались в межах чотирьох порядків) добре описуються одержаними теоретичними залежностями. Одержані одночасно дозові залежності фосфоресценції і релаксації струму провідності в різних зразках підтверджують, що час спустошення кожного типу пасток визначається не тільки імовірністю термічної делокалізації, а й співвідношенням концентрації цієї пастки до загальної концентрації більш глибоких пасток.

Experimental research has determined the optimal composition of components for a composite material used in electrical contacts with unique properties designed for high-current electrical apparatus that perform switching without arc formation. This article presents the results of a study on the porosity of copper obtained by the powder metallurgy method. To analyze the porosity of copper, methods for studying porous structures on both the surface and within the sample were examined. The metallographic method and the method of computed tomography were selected as the most suitable and informative. The conducted studies of the porous material revealed differences in material structure and porosity depending on various manufacturing conditions: temperature, process duration, and ingredient proportions. This, in turn, allowed for the identification of technological parameters for obtaining porous copper with up to 65% porosity, enabling its use as a matrix of the conductive material with a higher melting temperature. The optimal method for infiltrating copper samples with a low-melting material (fusible component) was selected.

Published: December 2024

We consider a topic modeling approach using latent Dirichlet allocation (LDA) methods aiming to examine patterns in the scientific research of Covid-19 using publications indexed in the PubMed database. A total of 4928 scientific abstracts published during the first semester of 2020 are taken into account. An LDA model is fitted using two topics. The first topic corresponds to risk factors, severity, and mortality due to viral infection, whereas the second is the impact of respiratory illnesses on public health. Our classification provides a global overview of these two research trends from the moment the analysis takes place. Additionally, our findings suggest that the systematic application of the proposed methodology provides a way to address and make more efficient the bibliographic review in academic contexts.

In this paper a modeling of the time series corresponding to the daily closing price of the Ecopetrol share between 2016 and 2018 is made. The methodology used is that of Box and Jenkins, which is developed step by step with the objective ofobtaining a model of the mentioned series that allows forecasting the value of the share in the short term. Initially, a description of the basic components of the series such as its trend, cycles and volatility is made; obtaining that the series is  stationary in average is constant through time. Then, with the use of the graphs of the autocorrelation and partial autocorrelation functions, a first ARIMA(2,0,1) model is postulated, observing that the residuals are not independent of each  other and in conclusion this model does not capture the dependence well. The study of the residuals is done with the purpose of analyzing the variance, for which the series of squared residuals is used, being these the estimators of the  conditional variances, obtaining that the model is good for the mean but not for the variance. Subsequently, the variance is modeled, analyzing the squared autocorrelation graphs, it can be determined from the Ljuan Box test that there is  heteroscedasticity in the residuals. Taking into account the above, an ARCH or GARCH model is sought to model the Ecopetrol price series, by means of the ARCH test, it is confirmed.that there is an effect of this nature.

Efficiency models are techniques used to measure the use of resources and their products or results, commonly called data management unit (DMU), which transform inputs into outputs to measure the efficiency of each study unit. Efficiency models make it possible to compare the different units in terms of results, taking into account their resources. In the present work, INPUTS or input variables are taken for each faculty and the outputs are reviewed, which in this case are the products of the 10 faculties of the Universidad Santo Tomás sectional Tunja, through the application of efficiency frontier models. To meet this objective, information was collected for a specific period through the measurement of different variables framed in the missionary axes of Higher Education in Colombia, namely: Training, Research and Extension or social projection. Two different efficiency frontier model approaches were applied: a parametric approach in which it is assumed that there is a known functional relationship between the input variables (inputs) and the output variables (outputs) by fitting a stochastic frontier model (SFA) and a non-parametric approach in which the data envelope model (DEA) is applied. It was possible to identify which faculties achieve their greatest efficiency with lower inputs, as well as variables that can be improved to achieve greater efficiency in the faculties with lower results. With this work it is expected to provide a management tool that allows generating plans for improvement and optimization of its resources.

Authors: Miró i Comas Abel
Published: December 2024

The aim of this article is to make a contribution to the open debate about the transcendence of beauty in Aquinas’ philosophy. To achieve this purpose, the text is divided into three parts. First, the classical fragment where the Angelic presents the systematic deduction of the transcendentals is examined; second, beauty is located within this deduction; and, finally, in a third concluding part, the reason of this silence is given.
Educadores en contextos de privación de libertad penitenciaria
Authors: Betancourt Ramírez Marisol Edilma
Published: December 2024

In this study, a systematic review of the literature was carried out using the PRISMA 2020 methodology to identify the current state of knowledge about the educational practices of teachers in educational centers in penitentiary establishments. The search was carried out in databases such as Scopus, Web of Science and Scielo, as well as Mendeley. Inclusion and exclusion criteria based on the PICoS strategy were applied, considering studies published between 2020 and 2024 in English, Spanish and Portuguese. The review revealed that few studies address the complexities within penitentiary learning communities and the system's regulations for training spaces for social reintegration of people deprived of liberty (PPL). The importance of disciplinary knowledge, skills and competencies of teachers was highlighted to offer an education that transcends the simple acquisition of knowledge, promoting the transformation and personal and social growth of PPL for their life in and for freedom.
Ciencia ciudadana aplicada en el recurso hídrico
Authors: Silva Hernández Francisca
Published: December 2024

In a complex system of understanding and attention to problems through science and research, citizen science represents a temporary incentive; It is not a new science, however, it can be strengthened and strengthened today more than ever. It infers a convergence of actors towards new paradigms and outside the walls, providing a panorama with more options aligned to the needs of the concrete reality based on a tacit finding. It is a science close to the convergence of scientists and societies to find, address and anticipate situations or problems that come together, its application in different sciences and disciplines contribute to experimental knowledge with a disciplinary, interdisciplinary and multidisciplinary scope. In the case of water resources, it favors obtaining results that imply the transversality of knowledge jointly and for the common good.

Published: December 2024

This article examines the characteristics of entrepreneurial university students in Colombia and the determining factors for initiating a business. A systematic literature review and a survey of 491 students from a Colombian university were conducted, utilizing the Random Forest algorithm for analysis. The findings highlight that education, life experiences, socioeconomic factors, and psychological aspects impact the decision to undertake entrepreneurial endeavors. Women predominate among entrepreneurs, and motivation, recognition of competencies, and risk aversion are crucial. It is suggested to allocate resources to motivate students with entrepreneurial potential, focusing on those in the fifth and seventh semesters, aged 20 to 39, and exhibiting leadership traits. The research underscores the importance of educational programs and awareness initiatives to enhance the entrepreneurial ecosystem, fostering successful entrepreneurship among university students in developing countries. This study contributes valuable information for the formulation of effective strategies in educational institutions and comprehends the factors influencing entrepreneurial intentions.

Published: December 2024

This mixed-methods study, employing inferential statistics and fuzzy logic, explores the perspectives of 75 Spanish Primary Education undergraduates on digital transmedia production practices aligning with children's values. It also investigates the potential in creating visual stories in English as an additional language. The students, worked in groups with a project-based methodology, collaborated on a storyboard, which they then made into a visual narrative and presented to their colleagues. The practicalities of recording, editing, adding audio and distributing the short videos were carried out with a wide range of devices, applications and software chosen by the students themselves, who demonstrated proactive attitudes in exploring the possibilities offered by the ICT resources. The progress of socio-emotional competences was also observed: negotiating agreements, finding divergent solutions, making decisions, and resolving conflicts and critically receiving feedback on their work. Likewise, when they reached the creative stage of the trial, they showed more confidence in themselves. The results showed that the undergraduates rated the visual storytelling approach highly, underlining that it was more involving and developed more competences. The study adds to the literature in favour of the following active methodologies: PBL, collaborative work, divergent models and Maker education.

This article is derived from a study whose objective was to determine the development of motor coordination in soccer players in the under 15 category of the Boca Juniors club training school in the city of Pasto-Nariño; It is important to highlight that in soccer, motor coordination is understood as the ability to order and organize motor actions oriented towards a determined objective with precision, effectiveness, economy and harmony, integrating all motor factors. The symptoms that cause difficulties in motor coordination in the practice of soccer in the population under study were detected mainly in their training, which generated physical overload and did not give importance to the coordination abilities, which generates a delayed reaction within the the practices and training of young soccer players. The research adopted a paradigm under positivism, which is a philosophical-scientific current, the quantitative approach that speaks of numerical data that is quantifiable, the empirical-analytical method, a type of explanatory-experimental research, with a population sample of 14 young soccer players, and some techniques and instruments for re-selection of information, where surveys, participant observation, test batteries and table of averages were applied. Already in the results part, first the sociodemographic and anthropometric variables of the athletes were characterized, the protocol of the test batteries (T test and Coda test) was implemented, to finally analyze the results found by the test batteries applied to the footballers from the Boca Juniors club, making an interesting comparison with a similar population from a club in Spain.

The relevance of the study lies in the importance of addressing gender issues comprehensively in adventure tourism, from acknowledging individual barriers to the need for cultural and structural transformations, recognizing the complexity of the problem, and the necessity for personalized and culturally sensitive solutions to advance towards greater gender equity. The labor situation of adventure tourism companies in communities in the southern state of Quintana Roo is analyzed through a gender perspective by conducting in-depth interviews with female and male workers, based on categories such as atypical hiring, wage discrimination, devaluation and invisibility, sticky floor, glass ceiling, and sexual harassment. Findings show that gender stereotypes exist in adventure tourism, highlighting a positive perception towards female leadership positions, albeit with stereotypes that limit the diversity of roles they can perform.
Uso de mejoradores cognitivos transcraneales en el deporte, consideraciones bioéticas para profesores y entrenadores
Authors: Caro Henry , Hoyos Luz Amelia
Published: December 2024

The aim was to develop global considerations from the field of Sports Bioethics, addressed to teachers and coaches, regarding the use of transcranial cognitive enhancers. These devices were created to electrically or magnetically stimulate the brain in order to enhance concentration, alertness, or memory. Sports bioethics focuses on investigating the ethical, social, and behavioral implications of this biotechnology, foreseeing that athletes may be unaware of the disadvantages to their health, face sanctions, and indirectly serve their marketers. A documentary review was used. Its achievements correspond to the clinical and sports field, but to a lesser extent. Advertising overestimates its scope. The conclusions emphasize the need to educate teachers and coaches about the bioethical implications of this biotechnology because its designers take advantage of the athletes’ lack of knowledge regarding its effectiveness, the regulatory vacuum and the absence of a legal framework.
