Error Analysis in Second Language Acquisition (SLA): Types and Frequencies of Grammatical Errors of Simple Present and Past Tense in the Elicited Written Production Task of Arab EFL Undergraduate Learners
Authors: Muftah Dr. Muneera
Published: July 2023

This investigation aimed to examine the types and frequencies of grammatical errors of present and past tense and agreement in the elicited written production task (EWPT) of Arab EFL learners. The sample of the study comprised 67 Arab EFL undergraduates selected through a simple random sampling method and subdivided into three proficiency levels. The data collection instrument was the EWPT, which consisted of two passages and a total of 46 test items. The EWPT was collected and the errors committed by the students were identified, classified, and analyzed in frequencies. Then, statistical analysis was performed using SPSS 21. The findings demonstrated two basic types of grammatical errors: error of misformation (EM) and error of omission (EO). Overall results revealed that incorrect use of inflectional morphemes was higher for the EM than for the EO of inflectional morphemes across the three groups of participants. The ungrammatical EM is characterized by the use of incorrect forms, including misusing phonologically similar words, incorrect suffixation, substitution, as well as overgeneralization of be verb forms. Based on these findings, some recommendations and pedagogical implications were proposed, which might assist EFL teachers in developing feasible teaching propositions and policies.

Published: July 2023

Contexto: Este estudio evalúa la estabilidad estructural de un rotor tipo Savonius implementando un perfil multielemento, con el propósito de reducir la resistencia al movimiento y mejorar así el rendimiento aerodinámico. El rotor con el perfil en estudio se comparó con rotores de perfiles semicircular convencional y Bach dividido.
Método: Se analizó la interacción fluido-estructura mediante la simulación numérica de los tres rotores, y se determinó el estado de esfuerzos y deformaciones en un régimen normal de operación. A los rotores se les asignó el mismo material de construcción, y estos fueron estudiados bajo los mismos parámetros y modelos de la dinámica de fluidos y mecánica computacional a través del software ANSYS.
Resultados: Los resultados obtenidos evidenciaron un mejor comportamiento estructural en el rotor con la configuración multielemento, al reducir el esfuerzo equivalente máximo en 59,10 y 42,87\% y las deformaciones en 47,40 y 33,59\% con respecto a los rotores de perfiles semicircular convencional y Bach dividido respectivamente.
Conclusiones: La configuración multielemento permite un mayor rendimiento aerodinámico y estructural, a la vez que se conserva la simplicidad de construcción y operacional que caracterizan al rotor tipo Savonius.
A Model for Documenting Requirements Elicitation
Authors: Serna M. Edgar , Serna A. Alexei
Published: July 2023

Context: This work proposes a model to document the elicitation of requirements in the field of Requirements Engineering.
Method: A systematic review of the literature was conducted to determine the validity and effectiveness of the existing models for documenting requirements elicitation.
Results: By analyzing the results of this review, it was concluded that it is possible – and that is required – to take the best documented practices and add principles from logic, abstraction, and formal methods to them in order to structure a semi-formal model for documenting elicitation. Those currently proposed focus on techniques to collect information and pay little attention to documentation. In addition, these models are mainly based on natural language, which makes their interpretation difficult, and they generate re-processing in later stages of the life cycle due to ambiguities.
Conclusions: This article describes a structured model, as well as its application and validation, by comparing it against five models found in the review.

Published: July 2023

The aim of the work is to analyze a clinical case of autoimmune hepatitis (АІН) diagnosis at the stage of cirrhosis in a 40-year-old female patient and to remind practicing doctors about the serious consequences of this disease.
Materials and methods. A clinical case of AIH diagnosed according to the criteria of the International Autoimmune Hepatitis Group (2008) at the stage of cirrhosis in a 40-year-old female patient was analyzed. A puncture liver biopsy with a morphological study of the hepatobioptate was also performed to verify the diagnosis.
Results. The analysis of the clinical case of AIH in a 40-year-old female patient revealed a delayed diagnosis of AIH at the cirrhosis stage. This was due to the absence of any clinical symptoms of the disease for a long period of time, and the lack of attention of practicing doctors in investigating the reasons for the long-term increase in transaminase activity. The trigger factor for the clinical manifestations of cirrhosis, which developed due to the long-term course of AIH, was emotional stress resulting from leaving the combat zone.
The application of the International Autoimmune Hepatitis Group criteria in clinical practice was demonstrated, specifically the combination of elevated antinuclear antibodies and total IgG, characteristic histological changes in the liver, and exclusion of hepatotropic viral infections, which allowed for a reliable diagnosis of AIH.
Medical treatment resulted in certain positive changes in clinical and laboratory indicators. However, according to the transplant doctor’s opinion, at this stage of the AIH course, the patient required a liver transplant and therefore was added to the waiting list.
Conclusions. This clinical case highlights the late diagnosis of AIH at the cirrhosis stage in a 40-year-old female patient due to the absence of clinical manifestations over several years and the lack of vigilance among doctors, possibly primary care physicians or specialists, to investigate the persistent increase in transaminase activity. The application of the International Autoimmune Hepatitis Group criteria helped confirm the diagnosis of AIH.
Microsurgical clipping of anterior communicating artery aneurysms as a method of prevention of repeated aneurysm rupture
Authors: Shkil І. О.
Published: July 2023

The aim of this study is to evaluate the efficacy of microsurgical clipping of anterior communicating artery (AComA) aneurysms as a method of prevention of repeated aneurysm rupture.
Materials and methods. A total of 98 patients were included in the study, with a mean age of 47.8 ± 11.0 years. The female-to-male ratio was 1.04 : 1.00. Aneurysms were verified using computer tomography of the head and neck vessels, selective cerebral angiography, and MRI angiography of cerebral vessels.
Results. Pterional access was used for surgical intervention in all patients. In the first three days after the aneurysm rupture, microsurgical treatment was performed on 18 of the most severe patients. After three days and later, surgical intervention was performed in patients with compensated and sub-compensated conditions. Patients were further examined; microsurgical tactics were carefully planned. Brain compression, pronounced dislocation, and occlusive hydrocephalus were indications for emergency surgery. Angiospasm was detected in 45 patients (45.9 %), among them pronounced angiospasm was detected in 36 %, widespread – in 20 %, intracerebral hematomas – in 30 (30.6 %), intraventricular hemorrhages – in 28 (28.6 %). In five cases, intracerebral hematomas led to pronounced compression of the brain and dislocation of the middle structures. These patients underwent hematoma removal and aneurysm clipping. Half of the patients had simultaneous intraventricular hemorrhages and intracerebral hematomas of the frontal lobes and the blood was most often localized in several ventricles. Four patients with decompensated hydrocephalus underwent ventricular drainage and CSF bypass operations before aneurysm clipping. Postoperative mortality in this group of patients was 11 %, and severe neurological deficits were 22 %.
It was established that repeated ruptures of AComA aneurysms occurred in 15 % of treated patients after admission to the hospital.
Conclusions. Microsurgical treatment provides a minimally invasive approach that minimizes damage to the surrounding brain tissue and helps preserve brain function and minimizes the risk of postoperative neurological complications.

Published: July 2023

Carboxylic acids and their derivatives are an important component of many biological processes. For example, they can be used to create new medicines that can be useful in the fight against various diseases. Additionally, compounds containing a thiazole moiety may possess beneficial properties in practical pharmacy. The incorporation of this heterocyclic structure in molecules can positively impact several biological characteristics, such as anti-inflammatory, antiviral, and antifungal activities.
Consequently, exploring novel compounds that combine a thiazole fragment with a carboxyl group holds promise for the advancement of new drugs and diagnostic tools that can contribute significantly to the battle against numerous diseases.
The aim of the work was to create a number of organic and inorganic salts of 6-(2,6-dichlorophenyl)-3-(3-methyl-1H-pyrazol-5-yl)-6,7-dihydro-5H-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazine-7-carboxylic acid and study of their properties, as well as selective determination of the biological potential of these compounds.
Materials and methods. The synthetic part of the study involved the sequential synthesis of the original compound 4-amino-5-(3-methyl-1H-pyrazol-5-yl)-1,2,4-triazole-3-thiol using a well-established method described in previous articles. The next stage involved the reaction of thiol with 2,3-dichlorobenzaldehyde in a medium of glacial acetic acid. The resulting Schiff base was subsequently reacted with 2-chloroethanoic acid in tetrahydrofuran in the presence of an equimolar amount of sodium hydride.
Salts of the corresponding acid were formed during the reaction of 6-(2,6-dichlorophenyl)-3-(3-methyl-1H-pyrazol-5-yl)-6,7-dihydro-5H-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazine-7-carboxylic acid with both organic and inorganic bases in an aqueous-alcohol medium. The structures of all synthesized compounds were determined using 1H NMR spectroscopy and elemental analysis. Additionally, the individuality of each compound was confirmed using high-performance liquid chromatography-mass spectrometry.
Results. The study determined the optimal conditions for the formation of both organic and inorganic salts of 6-(2,6-dichlorophenyl)-3-(3-methyl-1H-pyrazol-5-yl)-6,7-dihydro-5H-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazine-7-carboxylic acid. The analysis of pharmacokinetic parameters and physicochemical properties using ADME (absorption, distribution, metabolism, and excretion) allowed for the identification of promising synthesized compounds and the selection of more optimal compounds for further investigation.
Conclusions. The structure of 12 compounds was synthesized and confirmed. Physical-chemical and pharmacokinetic analysis of ADME parameters was carried out and promising compounds were selected for more in-depth research.

Published: July 2023

The heterocyclic system of 1,2,4-triazole enables the successful creation of promising biologically active compounds. By creating a range of derivatives based on 4-amino-3,5-dimethyl-1,2,4-triazole, the spectrum of potential biologically active compounds can be expanded.
The aim of the work was the synthesis and in silico justification of the prospects for the search for biologically active compounds among 4-amino-3,5-dimethyl-1,2,4-triazole derivatives.
Materials and methods. The work uses modern methods for synthesizing organic compounds, followed by confirmation of their individuality and structure through the analysis of physical-chemical parameters and spectroscopic techniques such as 1H NMR, IR spectroscopy, elemental analysis, and chromatography-mass spectrometry. To assess the similarity of the synthesized compounds to medicinal products, the SwissADME online tool was employed. The probability of impact on a number of enzyme systems (cyclooxygenase-2, lanosterol 14α-demethylase, anaplastic lymphoma kinase) was estimated using molecular docking.
Results. A series of newly synthesized derivatives of 4-amino-3,5-dimethyl-1,2,4-triazole was obtained, and the synthesis conditions were optimized and their structures were confirmed. It was determined that there is a high probability of influencing lanosterol 14α-demethylase, highlighting the significance of further research on the antifungal activity of the synthesized compounds. Additionally, the potential influence on the activity of cyclooxygenase-2 and anaplastic lymphoma kinase was discovered. However, the probability of exhibiting the corresponding activities, namely anti-inflammatory and anti-cancer, is low. Physical indicators, parameters of pharmacokinetics, and drug-likeness are important, which determines the prospects of creating biologically active substances based on the synthesized series of compounds.
Conclusions. A series of 4-((R-iden)amino)-3,5-dimethyl-1,2,4-triazoles were synthesized, and their general physical-chemical properties were determined. The overall potential for creating innovative biological products based on these compounds was assessed using in silico methods for predicting the activity of substances.

Authors: Smoilovska H. P. , Maliuhina O. O. , Yerenko O. K. , Khortetska T. V.
Published: July 2023

Tannins are an important class of secondary metabolites with a wide range of pharmacological effects, due to which they are used in various fields of treatment. In plants of the genus Achillea L., tannins are the dominant class of compounds. This allows the use of plant raw materials and extracts of yarrow for the development of complex herbal and combined formulations of medicines. The search for new sources of natural tannin compounds for pharmaceutical and cosmetic purposes is of significant interest and encourages the improvement of phytochemical research methods of known species of medicinal plants.
The aim of the work was to develop a spectrophotometric method for determining the quantitative composition of tannin compounds in terms of gallic acid in the herb of Achillea millefolium L.
Materials and methods. The study utilized dried air-dried raw material of yarrow for analysis. The quantitative content of polyphenols in the plant material was determined using a modified UV spectrophotometric method, with calculations based on pyrogallol equivalents. The development of the spectrophotometric technique for determining tannins from the herb of Achillea millefolium L., expressed as gallic acid equivalents, considered the effects of extractant concentration and the degree of plant material grinding.
Results. The water extract from the herb of Achillea millefolium L. exhibited a quantitative content of polyphenols, calculated as pyrogallol equivalents, at 2.9781 ± 0.0177 %. It was observed that the particle size of the raw material significantly influenced the yield of active substances. The optimal technological parameters for the developed method involved extracting plant material that was crushed to a size of 0.5–1.0 mm, using 70 % ethanol in a ratio of 1:10, resulting in a yield of 4.08 ± 0.01 %.
Conclusions. Based on the obtained results, it is recommended to utilize the developed method, employing gallic acid equivalents, for the quantification of tannins in alcohol-water extracts of yarrow.

Each patient presents a unique set of characteristics and challenges when it comes to acute cerebral ischemia resulting from craniocerebral injury.
The aim of this study is to investigate the utilization of Thiocetam as part of a comprehensive treatment approach for combat-related cerebral contusion and to assess the therapeutic effects of Thiocetam in patients with mild and moderate closed combat craniocerebral trauma in comparison to standard basic therapy.
Materials and methods. 79 patients with mild and moderate closed combat craniocerebral trauma were examined. Among them, 76 patients experienced craniocerebral trauma due to an explosive blast injury, which included conditions such as brain concussion, mild cerebral contusion, and cranial vault fractures. All patients were admitted to the department during the acute period of their injuries.
During the study, various clinical and functional methods were employed to assess the condition of the central nervous system. These methods were used to evaluate the effects of the complex treatment administered to the patients.
Results. The administration of Thiocetam to the patients did not result in an increase in excitability, nervousness, or sleep disturbances. Furthermore, the examination of autonomic reactivity following Thiocetam treatment revealed that the indicator of normal autonomic reactivity increased to 60 % in the treated group, whereas it only increased to 42 % in the control group. Additionally, the patients with initially heightened vegetative reactions experienced a decrease from 42.8 % to 17.9 % in the treated group, while the control group saw a decrease from 38.5 % to 23.1 %. In terms of clinical outcomes, a positive effect was observed in 94 % of patients in the Thiocetam-treated group within the first 5 days. In comparison, the control group showed a positive clinical effect in 76 % of cases. This improvement was evident both in the clinical field and based on indicators of autonomic reactivity in EEG data, as well as cognitive function assessed by the MMSE cognitive function test scale.
Conclusions. The utilization of Thiocetam during the acute phase of mild and moderate closed combat craniocerebral trauma enhances the neuroprotective effects of basic therapy. The combined drug Thiocetam, which possesses both nootropic and neuroprotective effects, offers the advantage of reducing or even avoiding the side effects commonly associated with traditional racetam nootropics.
Second Chern-Einstein metrics on four-dimensional almost-Hermitian manifolds
Authors: Barbaro Giuseppe , Lejmi Mehdi
Published: July 2023

We study four-dimensional second Chern-Einstein almost-Hermitian manifolds. In the compact case, we observe that under a certain hypothesis, the Riemannian dual of the Lee form is a Killing vector field. We use that observation to describe four-dimensional compact second Chern-Einstein locally conformally symplectic manifolds, and we give some examples of such manifolds. Finally, we study the second Chern-Einstein problem on unimodular almost-abelian Lie algebras, classifying those that admit a left-invariant second Chern-Einstein metric with a parallel non-zero Lee form.

A modified power-law model: Properties, estimation, and applications
Authors: Shrahili Mansour , Kayid Mohamed
Published: July 2023

Models of various physical, biological, and artificial phenomena follow a power law over multiple magnitudes. This article presents a modified Pareto model with an upside-down shape and an adjustable right tail. The moments, quantiles, failure rate, mean residual life, and quantile residual life functions are examined. In addition, some stochastic ordering characteristics of the proposed model are investigated. The estimation of the parameters using the maximum likelihood estimator, the mean square error, and the Anderson–Darling estimator is explored, and a simulation study is conducted to analyze their behavior. Finally, we compare the proposed model with alternative methods for describing a dataset on the strength of carbon fiber and a dataset on customer waiting times in a bank.
Heard or Understood? Neural Tracking of Language Features in a Comprehensible Story, an Incomprehensible Story and a Word List
Authors: Gillis Marlies , Vanthornhout Jonas , Francart Tom
Published: July 2023

Speech comprehension is a complex neural process on which relies on activation and integration of multiple brain regions. In the current study, we evaluated whether speech comprehension can be investigated by neural tracking. Neural tracking is the phenomenon in which the brain responses time-lock to the rhythm of specific features in continuous speech. These features can be acoustic, i.e., acoustic tracking, or derived from the content of the speech using language properties, i.e., language tracking. We evaluated whether neural tracking of speech differs between a comprehensible story, an incomprehensible story, and a word list. We evaluated the neural responses to speech of 19 participants (six men). No significant difference regarding acoustic tracking was found. However, significant language tracking was only found for the comprehensible story. The most prominent effect was visible to word surprisal, a language feature at the word level. The neural response to word surprisal showed a prominent negativity between 300 and 400 ms, similar to the N400 in evoked response paradigms. This N400 was significantly more negative when the story was comprehended, i.e., when words could be integrated in the context of previous words. These results show that language tracking can capture the effect of speech comprehension.
Modulation of SK Channels via Calcium Buffering Tunes Intrinsic Excitability of Parvalbumin Interneurons in Neuropathic Pain: A Computational and Experimental Investigation
Authors: Ma Xinyue , Miraucourt Loïs S. , Qiu Haoyi , Sharif-Naeini Reza , Khadra Anmar
Published: July 2023

Parvalbumin-expressing interneurons (PVINs) play a crucial role within the dorsal horn of the spinal cord by preventing touch inputs from activating pain circuits. In both male and female mice, nerve injury decreases PVINs' output via mechanisms that are not fully understood. In this study, we show that PVINs from nerve-injured male mice change their firing pattern from tonic to adaptive. To examine the ionic mechanisms responsible for this decreased output, we used a reparametrized Hodgkin-Huxley type model of PVINs, which predicted (1) the firing pattern transition is because of an increased contribution of small conductance calcium-activated potassium (SK) channels, enabled by (2) impairment in intracellular calcium buffering systems. Analyzing the dynamics of the Hodgkin-Huxley type model further demonstrated that a generalized Hopf bifurcation differentiates the two types of state transitions observed in the transient firing of PVINs. Importantly, this predicted mechanism holds true when we embed the PVIN model within the neuronal circuit model of the spinal dorsal horn. To experimentally validate this hypothesized mechanism, we used pharmacological modulators of SK channels and demonstrated that (1) tonic firing PVINs from naive male mice become adaptive when exposed to an SK channel activator, and (2) adapting PVINs from nerve-injured male mice return to tonic firing on SK channel blockade. Our work provides important insights into the cellular mechanism underlying the decreased output of PVINs in the spinal dorsal horn after nerve injury and highlights potential pharmacological targets for new and effective treatment approaches to neuropathic pain.

SIGNIFICANCE STATEMENTParvalbumin-expressing interneurons (PVINs) exert crucial inhibitory control over Aβ fiber-mediated nociceptive pathways at the spinal dorsal horn. The loss of their inhibitory tone leads to neuropathic symptoms, such as mechanical allodynia, via mechanisms that are not fully understood. This study identifies the reduced intrinsic excitability of PVINs as a potential cause for their decreased inhibitory output in nerve-injured condition. Combining computational and experimental approaches, we predict a calcium-dependent mechanism that modulates PVINs' electrical activity following nerve injury: a depletion of cytosolic calcium buffer allows for the rapid accumulation of intracellular calcium through the active membranes, which in turn potentiates SK channels and impedes spike generation. Our results therefore pinpoint SK channels as potential therapeutic targets for treating neuropathic symptoms.
The Children’s Mission Ship
Authors: Beriont Carleigh
Published: July 2023

With money raised from children, the American Board of Commissioners for Foreign Missions purchased a ship in 1856 to support a mission to Micronesia. Drawing from children’s literature, newspaper articles, pamphlets, and missionaries’ letters, this article follows the “Children’s Mission Ship,” or Morning Star, from Boston to Ebon Atoll in the Pacific. It argues that missionaries viewed the Pacific not as a border or vast empty space, but rather as a “sea of islands” and as contiguous with “missionary settler archipelagos” throughout the Hawaiian Islands and North American continent. The article further argues that stories from the ship and the Micronesian mission helped forge a multi-generational capitalist and Protestant public that enacted and enabled subsequent American missionary and United States imperial expansion in the Pacific. This article is part of a special issue of Pacific Historical Review, “Religion in the Nineteenth-Century American West.”

Published: July 2023

This study aimed to examine the prevalence of children and adolescents in meeting The Singapore Integrated 24-Hour Activity Guidelines for Children and Adolescents and whether the number of guidelines met was associated to Quality of Life (QoL). Parents of youths aged 7 to 18 years completed an online questionnaire consisting of the Singaporean Children Lifestyle Questionnaire and the Pediatric Quality of Life (PedsQL™) 4.0 Inventory. Parents reported on the physical activity (PA), sedentary behaviour (SB), recreational screen time (ST), sleep, dietary habits, as well as the QoL of their children. Their responses were benchmarked against the Singapore Integrated 24-Hour Activity Guidelines. Survey results of 181 youths showed that more than 38% of children and adolescents did not meet any of four guidelines relating to PA, recreational ST, sleep, and diet. Daily moderate-to-vigorous PA (31.1 vs. 17.1 min) and ST (3.5 vs. 2.5 h) of adolescents were significantly higher than that of children (p <.05) while adolescent sleep was significantly lower than that of children (7.3 vs 8.5 h, p < .05). QoL scores were higher when more guidelines were met but the association was not statistically significant (p = .11). Ameliorative programmes to help more youths cultivate positive lifestyle habits are recommended.

Values can be taught through Physical Education
Authors: Bin Salleh Muhammad Shufi , Aviado Lynnette Krystall G
Published: July 2023

Previous studies have emphasized the potential of using Physical Education (PE) as a platform to teach values. However, few teachers are deliberate in their attempts to teach values through PE as many may not have the teaching strategies to achieve the affective learning outcomes. What is unknown currently is the starting point of newly trained PE teachers, specifically in Singapore’s context, Beginning Physical Education Teachers (BPETs), on their preparedness to teach in the affective learning domain. The purpose of the study is to listen to the “lived experiences” of BPETs through interviews on their strategies and challenges to incorporate the teaching of values in their classroom. Three BPETs (2M, 1F) with no more than 3 years of teaching experience from primary and secondary schools were invited to participate in the study. Individual interviews were conducted and transcribed verbatim. The transcript was analysed using thematic analysis. The findings highlighted three common themes: 1. PE being a platform to see values in action; 2. Discussion on values and what it means in students’ lives; and 3. Reflection on their BPET journey. The findings show that BPETs believe that values can be taught through PE, and they would attempt to teach values in explicit or implicit ways. However, some teachers suggested specific courses that could equip them with the strategies to teach values specifically in a PE setting. Future studies can consider interviewing senior PE teachers on their experiences and strategies teaching values through PE.
Students' Way of Life and Academic Performance During the COVID-19 Pandemic
Authors: Maghanoy Vanessa Salomon , Adolfo Myiella R.
Published: July 2023

In order to understand how a student's way of life may affect their academic performance and conduct when studying online, this study looks at the relationship between the two. This study used quantitative correlational research to determine the respondents' academic achievement and way of life during COVID-19. The research participants in this study were chosen via stratified sampling, and standardized questionnaires were made available via a Google form. Since the p-values are more significant than the 0.05 level, the results show no correlation between the respondents' way of life and academic performance. This indicates that the student's way of life has little bearing on how well they succeed academically. When the students are classified according to their personality type profiles, there is a noticeable variation in their way of life. This implies that the student’s way of life varies depending on their personality types.

This article is part of the results obtained from the research project Geodimensionando el delito in Clorinda City (Argentina) and the territories of insecurity [Geodimensioning crime in Clorinda City (Argentina) and the territories of insecurity], conducted in the Geography Career of the School of Humanities at the National University of Formosa. This study aimed to know the perception of insecurity that residents of Clorinda have in their city, to determine sectors considered topophobic, and to identify specific places where fear of crime is greater than in the rest of the city. To achieve these goals, the study implemented a structured questionnaire as a data collection instrument us-ng the survey technique. Then, an analysis scale was used; it allowed differentiating neighborhoods based on the sense of insecurity of the neighbors, making it possible to classify these areas in reference to the high, medium, or low perception of insecurity. This was followed by the identification of neighborhoods subject to residential stigmatization by neighbors. Clorinda is a case of special interest, as it is a border city that is also close to Asunción, the capital of the Republic of Paraguay; this proximity favors a permanent movement of people from one side of the border to the other.

Implementing a quantitative method based on data collection and analysis made it evident that, during the last two decades, a rapid advance of the agricultural frontier for corporate agricultural and livestock production occurred. This advance resulted in the occupation of territories that, towards the end of the 20th century, were still considered marginal. Furthermore, to cause most changes in land use in the territory, deforestation increased in significant land areas; this allowed inferring that running capitalist agribusiness implied the destruction of a large part of the native forest. Consequently, the territory underwent important transformations due to a productivist model that triggered land concentration and a tendency to disarticulate Family agricultura.

In Mexico, protecting forests and jungles through a set of practices and efforts aims at preventing activities that affect them. These practices are divided into three categories within a fire management framework: cultural prevention, physical prevention, and le- gal protection. Within cultural prevention, studies on indices and probability models of fire occurrences stand out. The objective set forth in this work has been to present the different methodological proposals of indices and models developed in Mexico to predict the occurrence of forest fires, analyzing their methodological approaches and variables used. Digital and printed bibliographic materials from the end of the 20th century to 2018 were searched. Thirty-eight models and indexes were identified. The states of Durango and Mexico stand out with more than three studies each. These results make evident the lack of hazard systems in vast regions of the country.
Las evaluaciones externas en Suecia, Países Bajos y Dinamarca
Authors: Romero-León José Luis
Published: July 2023

El presente trabajo presenta el análisis de un estudio comparado más amplio sobre las evaluaciones externas en tres países de Europa. La misma se basa en el análisis de fuentes secundarias producidas entre 2005 y 2010. El estudio se completará con el análisis de otras fuentes producidas desde entonces, aunque esta tarea aún no ha finalizado. Con un primer objetivo descriptivo, el análisis se ha realizado a partir de una lógica deductiva, partiendo de una serie de categorías previamente definidas. El segundo objetivo de tipo analítico-crítico será desarrollado cuando finalice la fase dos del análisis documental. Por tanto, en este caso las conclusiones se centran exclusivamente en mostrar convergencias y divergencias de las evaluaciones externas en estos países.
La LOMCE bajo una mirada de género/s: ¿Avances o retrocesos en el s. XXI?
Authors: García Luque Antonia
Published: July 2023

En este trabajo se va a realizar una reflexión crítica en torno a la regresión sufrida en materia de género en la última ley orgánica educativa española (LOMCE). Para ello se va a analizar dicha legislación desde una perspectiva de género, centrándonos en la presencia o ausencia de las identidades de género y la diversidad afectivo-sexual tanto en el currículum como en la ideología que la fundamenta, así como también se va a realizar un diagnóstico de las medidas y actuaciones educativas que recoge dirigidas a la prevención y erradicación de la violencia de género.
Perspectiva europea de las Evaluaciones externas. El caso de España desde la LGE hasta la LOMCE
Authors: Romero León José Luis
Published: July 2023

Las evaluaciones externas que se vienen realizando en la mayoría de los países, y la importancia que han adquirido, son los ejes fundamentales de este artículo, que tiene como objetivos, por una parte, contextualizar a nivel europeo las evaluaciones externas fijándonos en dimensiones como su estatus, los órganos responsables, el uso de los marcos conceptuales, los procedimientos de las evaluaciones externas, las consecuencias que éstas tienen y la difusión de sus resultados a nivel europeo y, por otro lado, analizar la evolución que han tenido estas evaluaciones externas desde su primera mención en la LGE (Ley General de Educación) de 1970 hasta el cambio de paradigma evaluativo que, sin duda, ha tenido la implantación de la LOMCE (Ley Orgánica de Educación para la mejora de la calidad educativa). A modo de reflexión, y tras contextualizar las evaluaciones y ver su evolución histórica, proponemos una serie de aspectos que aportan una visión crítica a las nuevas funciones de las evaluaciones externas en LOMCE.
La Agencia de Calidad de la Educación ¿Una política de evaluación integral?
Authors: Carrasco Alejandro , Urrejola Antonia
Published: July 2023

Este artículo analiza el sistema de evaluación de la educación de Chile surgido a partir de la reforma de 2009. La hipótesis de este trabajo plantea que La Agencia de Calidad de la Educación no es un sistema de evaluación integral, como lo afirman sus documentos y leyes del país, sino una reforma basada en estándares que ha empobrecido el currículum nacional, influenciado negativamente el trabajo docente, donde predomina el carácter fiscalizador y el énfasis en los resultados de pruebas estandarizadas, subordinando la orientación para el logro de una formación integral de los estudiantes. Resultado propio de sistemas influenciados por los procesos de globalización y mercantilización de la educación.
La nueva organización de los tiempos escolares en los centros de Elche. Un debate abierto
Authors: Escudero Medina Consuelo
Published: July 2023

La jornada continua ha sido, en los últimos años, la principal reivindicación de los maestros valencianos. Recientemente, el debate sobre el tiempo escolar ha vuelto a surgir y, por ende, el choque de intereses. El presente trabajo pretende abordar la problemática surgida a propósito de la publicación y posterior ejecución de la Orden 25/2016 en los centros escolares de la Comunidad Valenciana. Para ello, este trabajo examina las deficiencias de la Orden y la polémica situación social derivada de la misma. Asimismo, analiza el rol de los principales actores en este tema: la Administración, el profesorado y las familias, así como la posición de las autoridades científicas al respecto. En definitiva, el estudio intenta poner de relieve la complejidad de este debate.
Mercado escolar, marketing y segregación: Un estudio exploratorio sobre el uso de publicidad en escuelas de Santiago de Chile
Authors: Oyarzún Maldonado Cristian , Soto González Rodolfo , Moreno Díaz Karina
Published: July 2023

En el sistema escolar chileno, caracterizado por dinámicas mercantiles y marcada segregación, el uso del marketing constituye una estrategia de promoción de servicios para captar y fidelizar usuarios. Este artículo examina la distribución en el espacio socio-geográfico de la publicidad de 1383 escuelas de la provincia de Santiago de Chile. Para ello se utilizó un enfoque cuantitativo que permitió establecer relaciones estadísticas entre la presencia de afiches publicitarios y variables como grupo socioeconómico (GSE), dependencia administrativa y ubicación geográfica de las instituciones escolares. La evidencia empírica revela que el uso de publicidad se relaciona de manera significativa con variables como el GSE de las familias, la dependencia y las características sociales de la comuna donde se ubican las escuelas. Los resultados son discutidos en base a los antecedentes teóricos y las características estructurales del modelo escolar chileno.

La libertad de cátedra y el papel de la guía docente en la Universidad derivada del Espacio Europeo de Educación Superior
Authors: Jarne Muñoz Pablo
Published: July 2023

Este trabajo analiza la evolución que la libertad de cátedra ha venido experimentando en nuestro país, prestando especial atención a las características que el Espacio Europeo de Educación Superior le ha atribuido. Más concretamente, a lo largo de estas páginas se plantea una reflexión sobre la incidencia que uno de los instrumentos claves del EEES, la guía docente, puede desarrollar sobre la libertad de cátedra. A pesar de que se trata de un instrumento con evidentes posibilidades ordenadoras, es necesario plantearse si su configuración no resulta excesivamente limitativa en relación con la libertad de cátedra atribuida a los docentes.
Historias de vida de personas con discapacidad intelectual. Entre el acoso y exclusión en la escuela como moduladores de la identidad
Authors: Mañas Olmo Moisés , González Alba Blas , Cortés González Pablo
Published: July 2023

Este artículo muestra parte de los resultados de una investigación llevada a cabo con cuatro personas diagnosticadas con discapacidad intelectual (PCDI), que viven en un centro terapéutico. El propósito de este texto se centra en analizar las trayectorias escolares y sus repercusiones en la construcción de la identidad de los mismos a través de sus relatos de vida, accediendo, de este modo, a historias en torno a la exclusión, el sufrimiento, el estigma... pero también a la transformación. Esto último resulta ser un factor esencial para comprender uno de los resultados del estudio: la resiliencia como proceso para la dignidad vital.
