Hydrological Modeling and Evaluation of the Efficiency of Culverts in Drainage Basins Affecting the North Railway in Wadi Malham
Authors: Alqreai Fatmah Nassir , Altuwaijri Hamad Ahmed
Published: October 2023

The North Railway is one of the longest railway lines in the world, extending for 2750 km from the Riyadh region to Al-Jawf Province through many diverse topographies, including valleys where direct runoff is generated that cross the existing hydraulic protection installations on the railtrack. Direct runoff flows in quantities that exceed the capacity of existing drainage installations and cause several types of damage, owing to the nature of the drainage basins and the impact of changing natural factors and human errors. To ensure the safety of the design of hydraulic drainage installations, this indicates the need for hydrological studies of drainage basins, especially those that include important strategic facilities such as railway lines. In this study, the hydrological modeling of four subdrainage basins (No. 6, 7, 13, and 14) within Wadi Malham was applied and evaluated to determine if the drainage installations can accommodate the direct peak runoff flow. According to the results, the peak flows of 8.9 m3/s for basin No. 7 and 18.2 m3/s for basin No. 13 indicate that they are unable to handle the direct peak runoff flow from the designed storm for a return period of 100 years. The other two basins are able to pass through the peak flow. Based on the findings of this study, we recommend adding an opening for culvert C0400 in basin No. 7 and adding two openings for C0244 in basin No. 13 to accommodate the peak flow.

Authors: Mohsen Mousa S. , Matarneh Rana
Published: October 2023

Interior designers play a pivotal role in shaping the built environment and catalyzing positive change through the adoption of sustainable design practices. This study centers on the analysis of prevailing attitudes held by interior designers in Jordan towards sustainable interior design practices. Through a comprehensive methodology involving a literature review and a three-part questionnaire, the research explores the benefits, challenges, and integration of sustainability principles. The study highlights substantial awareness (85%) of sustainable interior design’s environmental impact and resource preservation. Additionally, 81% acknowledge its enduring significance and 89% recognize its diverse benefits. While 61% exhibit familiarity and 27% claim professional experience. Among sustainability indicators, energy efficiency scores 4.25, resource efficiency 4.27, and “Design aligns with laws and regulations by the Ministry of Labor” ranks highest at 4.37. This study significantly augments our understanding of sustainable interior design by introducing a comprehensive evaluation framework that encompasses the three sustainability dimensions. It equips decision makers with a robust tool to identify specific practices that bolster sustainability performance, further advancing the field. Furthermore, this study provides practical strategies for the application of sustainable interior design principles in the Jordanian context, emphasizing the need for hands-on training, interdisciplinary collaboration, policy development, and ongoing monitoring. These strategies aim to bridge the gap between awareness and practical experience, fostering a culture of sustainability within the interior design profession. The findings of this research resonate with existing literature on sustainability in the built environment, demonstrating a global shift towards sustainability as a fundamental approach rather than a passing trend. The introduced comprehensive evaluation framework equips decision makers with a robust tool to identify specific practices that bolster sustainability performance, further advancing the field of sustainable interior design in Jordan and beyond.
Engineering the Tensile Response of Glass Textile Reinforced Concrete for Thin Elements
Authors: Paul Sachin , Gettu Ravindra
Published: October 2023

Textile-reinforced concrete (TRC) is a composite made with bi-directional non-metallic fabric embedded in a fine-grained cementitious matrix. When engineered appropriately, these composites can reduce material usage for the desired performance, resulting in slimmer sections and enhanced material efficiency, which in turn lowers the CO2 footprint. To facilitate the widespread application of TRC in practice, it is crucial to comprehend the material and structural behavior of these composites, which can pave the way toward an optimized design methodology. In this paper, the tensile response of TRC is studied with different textile geometries, volume fractions and matrix strengths. The influence of the coating impregnation on the effectiveness of the textile to enhance the response of the composite is discussed, with complementing evidence from microstructural observations. The results of tests with different textile configurations indicate a transition in the type of stress–strain response from tri-linear to bi-linear, beyond a certain effective volume fraction. The paper also presents a simplified model to predict the bi-linear response from the efficiency factor-based approach. The insights gained can assist in achieving composite designs with optimized sections and limited tensile stress cracking, ensuring the targeted performance in slender elements.

Published: October 2023

The concept of using wastewater as a substitute for limited water resources and environmental protection has enabled this sector to make major technological advancements and, as a result, has given us an abundance of physical data, including chemical, biological, and microbiological information. It is easier to comprehend wastewater treatment systems after studying this data. In order to achieve this, a number of studies use machine learning (ML) algorithms as a proactive approach to solving issues and modeling the functionalities of these processing systems while utilizing the experimental data gathered. The goal of this article is to use textual analysis techniques to extract the most popular machine learning models from scientific documents in the “Web of Science” database and analyze their relevance and historical development. This will help provide a general overview and global scientific follow-up of publications dealing with the application of artificial intelligence (AI) to overcome the challenges faced in wastewater treatment technologies. The findings suggest that developed countries are the major publishers of articles on this research topic, and an analysis of the publication trend reveals an exponential rise in numbers, reflecting the scientific community’s interest in the subject. As well, the results indicate that supervised learning is popular among researchers, with the Artificial Neural Network (ANN), Random Forest (RF), Support Vector Machine (SVM), Linear Regression (LR), Adaptive Neuro-Fuzzy Inference System (ANFIS), Decision Tree (DT), and Gradient Boosting (GB) being the machine learning models most frequently employed in the wastewater treatment domain. Research on optimization methods reveals that the most well-known method for calibrating models is genetic algorithms (GA). Finally, machine learning benefits wastewater treatment by enhancing data analysis accuracy and efficiency. Yet challenges arise as model training demands ample, high-quality data. Moreover, the limited interpretability of machine learning models complicates comprehension of the underlying mechanisms and decisions in wastewater treatment.

We integrated stomach content analysis (SCA) and stable isotope analysis (SIA) to understand ontogenetic niche shifts in the invasive freshwater fish, bluegill, Lepomis macrochirus, inhabiting the Yedang Reservoir in Korea. Based on the total length (TL), we classified L. macrochirus as small (23–57 mm), medium (61–99 mm), or large (100–163 mm). Across all study sites, the index of relative importance (IRI) of zooplankton was high for small individuals, whereas those of benthic macroinvertebrates were high for the medium and large groups. Isotopic niche width estimates based on carbon and nitrogen isotope ratios (δ space) also increased with growth, indicating an ontogenetic niche shift in L. macrochirus. In particular, the δ space and diet plasticity of large fish was higher in the littoral population, implying L. macrochirus are generalist feeders as adults. Individuals classified as small showed confined and constant δ space, regardless of habitat condition. Thus, together with the results on the significantly high IRI of zooplankton, these individuals seem to have strong specialistic feeding ecology. Our study demonstrates the applicability strength of combining SCA and SIA for ecological niche research by providing clear evidence of an ontogenetic niche shift in L. macrochirus and elucidates their feeding ecology.
Navigare necesse est: markets, crises, and our models
Authors: Székely P. István
Published: October 2023

The events of the past decade and a half have posed unprecedented challenges to macroeconomic policymaking. Modern policymaking has long been relying on a spectrum of models both at national and supranational levels. However, none of the standard models have predicted any of the major crises of the past decade and a half, nor could they capture the dynamics of the ensuing readjustment processes well. In general, standard workhorse models make several assumptions that may not hold in the economies they are applied to. Moreover, they perform particularly poorly during crisis episodes. This short article reviews the issues surrounding these models and proposes a simple modelling strategy to be applied in the face of such large model uncertainty.
Heuristics in the corporate credit process : A behavioural analysis of risk managers and credit officers
Authors: Kádár Béla , Romanoczki Dorisz , Jáki Erika
Published: October 2023

We investigate and compare the cognitive thinking of two key actors involved in the corporate lending process: business-side credit officers and risk analysts. We investigated four different heuristics – risk aversion, overconfidence, overoptimism and representativeness bias – through a questionnaire survey based on a previous experiment by psychologists. The eight banks included in the study are among the 12 largest banks in Hungary in terms of balance sheet total, and they are also active in the financing of the large corporate segment. The respondents are relationship managers and risk analysts working in the large corporate segment. The research is exploratory and comparative and uses qualitative research methods. Based on this research, we confirmed in a banking context that the decisions of relationship managers and risk analysts are characterised by cognitive biases. One of the limitations of the research is that the decision-making process was examined in fictitious situations rather than through a real credit assessment process. The research is novel because cognitive biases have not been studied in a bank lending context specifically for credit officers and risk analysts. The results are useful for optimising decision-making processes in banks.

Purpose. To evaluate the clinical and economic efficacy of the drug complex of beta-iron (III) oxyhydroxide, sucrose, and starch (Velphoro) in comparison with sevelamer in patients with stage 5 chronic kidney disease (CKD) receiving phosphate binding therapy during renal replacement therapy (RRT) in the conditions of the healthcare system of the Russian Federation. Materials and methods. An analytical decision-making model, which allows estimating the costs of managing patients with stage 5 CKD receiving phosphate binding therapy along with RRT, was built in MS Excel. The model included the costs of phosphate binding therapy with beta-iron (III) oxyhydroxide-sucrose-starch complex or sevelamer, as well as the cost and incidence of non-RRT hospitalizations in patients with CKD. The frequency of hospitalizations was determined according to a retrospective analysis of the data from End Stage Renal Disease Seamless Care Organizations (ESCOs), USA (2016-2018). The potential economic impact of using comparison strategies was calculated in 19,617 estimated patients with stage 5 CKD receiving RRT and phosphate binders. Results. The use of beta-iron (III) oxyhydroxide, sucrose, and starch complex in comparison with sevelamer is associated with a reduction in costs by 10,222 rubles or by 7.4 % on average per patient, which allows fully reimbursing the costs of more expensive drug therapy (the difference in costs minus the cost of drug therapy is 896 rubles in favor of the beta-iron (III) oxyhydroxide, sucrose, and starch complex), and reducing the number of hospitalizations in the target population by more than 6,000 cases. When used in the target cohort of patients, savings will amount to 200.5 million rubles (17.6 million rubles minus the difference in the cost of drug therapy). Conclusion. The use of beta-iron (III) oxyhydroxide, sucrose, and starch complex in patients with CKD during the RRT is clinically and economically feasible, as it allows reducing the number of hospitalizations and is characterized by fewer pills taken daily, reducing the overall costs of patient treatment.

The article presents the results of a study of phagocytosis parameters and levels of antibodies to SARS‑CoV‑2 in the blood of 26 doctors: 14 pediatricians and 12 residents of the clinical laboratory diagnostics. The data obtained revealed a reduced number of eosinophils and lymphocytes in the blood and higher values of phagocytic activity and levels of antibodies to SARS‑CoV‑2 in the pediatricians compared to the residents, which indicates a decrease in the reactivity of their body and a greater tension of natural protection factors. No significant correlation between antibody levels and phagocytosis parameters was found, which may indicate their autonomous response to a viral infection.

One of the most serious complications of the novel coronavirus infection is damage to the cardiovascular system, the main variants of which are acute and chronic myocarditis, as well as decompensation of existing cardiovascular diseases. Clinical manifestations of myocardial damage can be non-specific and blurred, with unknown long-term consequences for the patient. Therapy carried out in COVID-19 patients presents a potential threat to the myocardium. In the Samara Region in 2021–2022, medical workers were diagnosed with 10 cases of chronic occupational diseases associated with the novel coronavirus infection, which caused permanent disability. Of these, four patients were diagnosed with viral myocarditis, and one case was inflammatory dilated cardiomyopathy. The article presents a clinical case of the development of myocarditis associated with the novel coronavirus infection in a healthcare worker, with the establishment of its causal relationship with professional activities. The need for a multidisciplinary approach to the diagnosis and treatment of COVID-19, with the mandatory par ticipation of a cardiologist, is emphasized.

When a low fat content in grain feed, pigs lack energy, unsaturated fatty acids (linoleic, linolenic, arachidonic), which play the role of biocatalysts in the body. With a shortage of fats, the growth of animals, especially young animals, slows down. The purpose of the work was to study the meat productivity of pigs when using vegetable oils in their diets. The results of the study of the chemical parameters of meat indicate that the quality of pork was due to the eff ect of adding oil to the diet in diff erent amounts, because under the same conditions of housing and feeding diff erent values of individual qualitative indicators were obtained. In animals of the 1st experimental group (1,0 % soybean oil) of Large White breed compared with animals of the control group, an increased content of total moisture in the muscle tissue by 0,46 abs.% was noted and in crossbreds by 0,37 abs.%, which indicated the best technological qualities of meat and less losses during cooking. The muscle tissue of pigs of the 1st experimental group in purebred and crossbred pigs contained 2,22 abs.% more fat than in the control group. There was more fat in the control group than in the 2nd experimental group by 1,60 abs.%. Pork in the 1st experimental groups both purebred and crossbred pigs due to the higher content of soy oil in the diet had a better organoleptic evaluation. The expediency of using vegetable oil when feeding young pigs of Large White breed and its crossbreds has been revealed. At the same time, the best results were noted when 1,0 % soybean oil was included in the compound feed. The dosage in the amount of 0,5 % soybean oil did not give positive results compared with the same dosage of sunfl ower oil in compound feed for the control group.
Investigating English Teachers’ Perceptions of English language Education through the Q Method
Authors: Ünsal Fırat , Kasap Süleyman
Published: October 2023

Educators, politicians, and scholars have been interested in English language education for many years. Despite the rising significance of English as a global language, there still needs to be agreement on the most effective techniques for teaching English language skills. Understanding the opinions and attitudes of English instructors towards language instruction might assist in shaping educational practises and initiatives. This research sought to evaluate English instructors' perspectives on English language education using the Q approach. Q methodology is a research strategy that enables people to rank and prioritise their ideas on an issue, allowing for a more nuanced understanding of people’s viewpoints. The research included 40 English language instructors from various areas of Turkey who were asked to rate 20 English language education statements based on their degree of agreement. A survey of the literature and conversations with instructors and students were used to construct the assertions. The study’s findings indicated three unique points of view among English language instructors, which the researchers named "Traditionalists," "Idealists," and "Realists." Traditionalists felt that language learning should be based on knowledge of linguistic norms and emphasised the significance of grammar and translation abilities. The Idealists felt that language study should strengthen students’ abilities to communicate and comprehend diverse cultures and that communication and critical thinking skills should be prioritised. Realists emphasised practical abilities and tactics that can be used in everyday life, and they felt that language instruction should be relevant to students personal and professional aspirations. The research finds that varied opinions and attitudes towards English language education among English instructors might impact their teaching practises and tactics. The research also emphasises the necessity of knowing teachers’ opinions on language instruction and the possible advantages of investigating instructors’ perceptions using the Q technique. This research has practical consequences for language education policy and teacher education programmes.

Published: October 2023

Sense of humour can be a valuable asset for teachers in various ways. For starters, it can aid in creating a positive and enjoyable environment for learning, which can promote student engagement and motivation. Teachers who use humour in the classroom can help to break down barriers and foster a sense of community among students and teachers. This, in turn, can lead to improved relationships and a more positive classroom climate. Therefore sense of humour is an essential trait for a teacher to manage the classroom successfully. Further the humour style followed by the teacher will also impact the environment of classroom, positive style of humour will lead to positive effects while negative humour style will lead to negative effects. This study has attempted to assess the level of sense of humour and the style of humour among the prospective teachers with special reference to selected independent variables. The present study uses simple random sampling technique to select 70 prospective teachers belonging to two year B.Ed programme and Four-year integrated programme as samples. The study shows that prospective teachers have above average level of Sense of Humour and majority of them were following affiliative style of humour.

Authors: Abishek U
Published: October 2023

Film is an influential medium to catalyze the social change. Like other fine arts film is both a piece of social reality and a vehicle of depicting the True-reality rather than idealizing and stereotyping it. Films have unpretentious effect on society’s perspective. Film has without a doubt contributed a great deal to the strange development in India. Sexual minority comprises of that multitude of individuals who fall under the classifications of Lesbians, Gays, Bisexuals and Transsexuals. Projection of orientation generalizations in films shapes society’s view of orientation jobs. The over-immersion of the sexual orientation generalizations in the movie, KA Bodyscapes directed by Jayan K.Cherian, brings about the deception of orientation which gets implanted in the human psyche and is given from one age to another as an adequate view.

Розглянуто процеси термічної конверсії деревини в комбінованому шаровому газогенераторі. Виділено процеси газогенерації та піролізу. Загальноприйнятий підхід передбачає опис таких процесів за допомогою різних моделей. Зазначені процеси не мають різких меж і при зміні зовнішніх впливів можуть плавно переходити один в інший. Виникає проблема опису процесу на такій межі. Різні моделі на межі переходу одного процесу в інший можуть визначати різні склади продуктів реакції за однакових параметрів процесу. Запропоновано модель на базі рівноважних хімічних реакцій, що однаково описує процеси піролізу та газифікації. Для демонстрації її можливостей при мінімізації обчислювальних витрат розглянуто тільки випадок кисневого дуття при використанні деревини різної вологості. Запропонована модель дає змогу врахувати як утворення газоподібної фази продуктів термодеструкції вихідної сировини, так і конденсовану фазу у вигляді вуглистого залишку (деревного вугілля). Отримані результати розрахунків порівняно з експериментальними даними різних авторів. Однією з особливостей наведених у літературі експериментальних даних є широкий розкид їхніх значень для одних і тих самих вихідних умов. Пропонована модель дає змогу побудувати платформу для однакового їх пояснення. Збільшення в моделі переліку можливих хімічних реакцій дасть змогу в рамках єдиного підходу досліджувати процеси горіння, піролізу та газифікації. Можливість врахування наявності в продуктах реакції конденсованої фази та розширення моделі дасть змогу: досліджувати процес термічної деструкції різноманітних органічних речовин, зокрема побутових відходів, використовувати різні окислювальні агенти, враховувати різний спосіб внесення додаткової зовнішньої енергії. Наслідком розширення моделі буде збільшення кількості рівнянь у системі алгебраїчних нелінійних рівнянь і, відповідно, деяке ускладнення її розв'язання.

Внаслідок недостатньо ефективного перемішування матеріалу в початковій частині барабана кульового млина подрібнююче середовище втрачає ефективність роботи, що приводить до перевитрати електричної енергії, куль і футерівки. Дослідженням даного процесу займався ряд авторів в Україні і за кордоном, починаючи з середини 70-х років минулого століття. Запропоновані моделі досліджень, критерій перемішування у вигляді імовірнісного коефіцієнта, який може змінюватися в межах 0…1. Однак нині задачі перемішування матеріалу в кульових млинах до кінця не вирішені. Відсутня загальна оцінка пульсацій матеріалу в барабані, не оцінено стан матеріалу на початковій ділянці і не запропоновано підходів до його покращення. Зрозуміло, що вихід з даної ситуації можливо знайти в удосконаленні кульового млина шляхом покращення його характеристик. Дослідження виконані в межах реалізації теми «Оптимізація продуктивності кульових млинів по руді і готовому продукту при мінімальних енергетичних і матеріальних перевитратах», яка входить до наукової тематики Центральноукраїнського національного технічного університету. З погляду на це тема статті є актуальною. Метою даної роботи є зменшення перевитрат електроенергії, куль і футерівки в процесі подрібнення сировини покращенням характеристик кульового млина удосконаленням завантаження руди, пісків спірального класифікатора та води на основі оцінювання пульсацій матеріалу на початковій ділянці барабана. В процесі досліджень використано метод порівняння, аналізу, методи теорії кульових млинів, теорії автоматичного керування, теорії імовірностей, математичної статистики, теорії випадкових процесів. За допомогою комп’ютерної обробки масиву даних за спеціальною програмою отримані області зміни коливальних параметрів на вході кульового млина по твердому і воді, при яких відносні відхилення маси матеріалу в агрегаті не перевищують ±3,0%, що гарантує нормальний хід технологічного процесу. Встановлено, що як по твердому, так і по воді самими небезпечними є коливання з занадто малою частотою і значними амплітудами. Важливою є проблема перемішування матеріалу в початковій частині барабана кульового млина, оскільки тут низька ефективність осереднення. Найбільш доцільним є шлях, спрямований на покращення умов перемішування ліквідацією існуючих недоліків. По-перше, перед входом руди в млин її необхідно змочити частиною потоку води, а піски перед входом в завитковий живильник максимально розрідити другою частиною потоку води. Третю частину потоку води в млин необхідно розбризкати в широкій зоні входження руди в технологічний агрегат. Такі операції забезпечують ефективне перемішування і подрібнення матеріалу вже в початковій ділянці барабана млина. Збурюючі впливи по потоку руди не порушують технологічний режим кульового млина.
ФОРМОУТВОРЕННЯ СФЕРИЧНИХ ЕПІЦИКЛОЇД ПРИ ОБКОЧУВАННІ РУХОМОГО КОНУСА ПО НЕРУХОМОМУ

Багато плоских кривих мають сферичні аналоги. Їх об’єднують однакові способи утворення. Одним із таких прикладів є утворення поверхні евольвентного зубчастого зачеплення. Для циліндричної передачі утворення поверхні зубця відбувається слідом прямолінійної твірної циліндра, який котиться по площині. Ортогональним перерізом такої поверхні є евольвента кола. Для конічної передачі утворення поверхні зубця відбувається слідом прямолінійної твірної конуса, який теж котиться по площині. При такому коченні вершина конуса є нерухомою, а його основа – коло – утворює множину плоских перерізів сфери з центром у вершині конуса. При коченні конуса його основа всіма своїми точками лежить на сфері, отже нерухома точка кола опише сферичну криву – аналог евольвенти кола на площині. Цю криву можна отримати як результат перетину сфери із конічною поверхнею, яку утворює прямолінійна пряма конуса, що котиться по площині. Таким чином, утворення плоскої і сферичної евольвент подібне, при чому в одному випадку по площині котиться циліндр, а у другому – конус. Існує також сферичний еліпс, утворення якого подібне до утворення еліпса на площині. В обох випадках це є множина точок, сума відстаней від яких до двох фіксованих точок є величина стала. Відмінність полягає в тому, що в одному випадку відстані вимірюються відрізками прямих, а в іншому – дугами кіл, радіус яких дорівнює радіусу сфери. За аналогією можна побудувати сферичні аналоги циклоїди, гіпо- і епіциклоїди. Епіциклоїда утворюється слідом нерухомої точки рухомого кола при його зовнішньому перекочуванні по нерухомому колу. Відповідно для утворення сферичного аналогу епіциклоїди потрібно розглядати зовнішнє перекочування рухомого конуса по нерухомому. В статті здійснено аналітичний опис такого перекочування, який ґрунтується на тому, що основи конусів, які є колами, розташовані на поверхні сфери. За аналогією кочення кіл одне по одному у площині реалізовано кочення кіл одне по одному на поверхні сфери. Отримано параметричні рівняння сферичної епіциклоїди при такому перекочуванні. В частковому випадку, коли нерухомий конус має кут при вершині, рівний 180°, тобто перетворюється у площину, сферичною кривою є аналог циклоїди на площині. Здійснено візуалізацію отриманих результатів засобами комп’ютерної графіки.

With innovation serving as the primary driver, higher education institutions are essential to fulfilling the Sustainable Development Goal of quality education. Innovating in teaching means constantly adapting to new learning environments and changing audiences, but the advantage is that diversity remains constant. Making resources accessible in a variety of formats promotes inclusiveness, quality and flexibility to different learning preferences and styles, which supports a culture of lifelong learning. In a resource-constrained environment, lecturers often do not have evidence of how this variety of materials benefits the learner. A teaching innovation project is proposed to find out the diversity in learning styles in the classroom as well as the preferences and evaluations of students about three types of materials provided by lecturers of a given lesson, presented through text, graphics and audio. The results have given us a better understanding of the teaching-learning process and the needs of students.
Política e Ineficiencia en Seguridad: Efectos en las MiPymes y el Nivel de Inflación en México
Authors: Andrade Rosas Luis Antonio , Guadarrama Muñoz Alma Cossette , Tapia Betanzos Gabriela
Published: October 2023

A partir de datos de INEGI (2022) sobre rubros en México, se analiza el comportamiento de sobrevivencia de distintas empresas. El análisis muestra que solo tres empresas sobreviven más de 30 años y el 85% del total alcanza a sobrevivir 25. Respecto a esto, los niveles de delincuencia sobre las empresas es una de las razones del no posicionamiento y creación de nuevas empresas, en particular las MiPymes. También, se analiza cómo la delincuencia afecta el posicionamiento de estas, decreciendo la oferta de productos e implicando mayor inflación en zonas del norte del país. Finalmente, se reflexiona sobre la acción del gobierno a través de políticas en seguridad para mitigar los cierres, aumentando la oferta y disminuyendo la inflación.
Ley Aula Segura y su Impacto en la Violencia Secundaria en la Comuna de Santiago ¿Política Pública del Fracaso?
Authors: Ocampo Alex
Published: October 2023

En 2018, se instauró en la discusión política la necesidad de disminuir los hechos de violencia que ocurrían en los centros de educación en la comuna de Santiago, naciendo así la denominada Ley «Aula Segura». El problema surge cuando una política de seguridad pública no genera los resultados esperados, aumentando los hechos de radicalidad mediante la perpetración de eventos de violencia física y simbólica. El propósito del ensayo se centrará en verificar si una política punitiva de persecución penal puede solucionar un problema que va más allá de la seguridad pública. Finalmente, se buscará explicar los problemas del contexto político social previo a la normativa y los impactos de la implementación de Ley «Aula Segura».
Aproximación al concepto de enodiplomacia y estudio de percepción sobre su gestión e impacto en la imagen territorio de Alicante
Authors: Torres Valdés Rosa María
Published: October 2023

A partir de la interrogante ¿en qué medida la comunidad valenciana ha aprovechado el vino de Alicante para promover su imagen internacional, su prestigio, sus exportaciones y su propuesta turística?, desarrollamos un estudio del concepto de enodiplomacia desde la opinión de los productores alicantinos, la Denominación de Origen Protegida (DOP) vinos de Alicante, docentes e investigadores del grado en Gastronomía de la Universidad de Alicante, divulgadores expertos y el análisis de diversas campañas sobre los vinos de Alicante. Se constatan diferencias entre las percepciones de estos actores en cuanto a los esfuerzos de promoción del vino alicantino, de defensa del territorio y su desarrollo sostenible; mismo modo, se identifican figuras que podrían considerarse embajadoras del vino en general, y de la “terreta” en particular. Se infiere la necesidad de ordenar un concepto como enodiplomacia desde diferentes aristas: gastronomía, turismo, ruralidad, producto y marca país.
Herança monástica na gastronomia e vinhos da região do Minho
Authors: Maia-Marques Gonçalo
Published: October 2023

A presente investigação propõe-se apresentar uma proposta de síntese em torno do papel que as Ordens Religiosas, em virtude do seu posicionamento privilegiado na região do Minho (Portugal), tiveram na afirmação e valorização do riquíssimo património gastronómico e vínico de que hoje dispomos. Nesse sentido, cruzam-se fontes primárias e secundárias, entre receituários, obras artísticas e trabalhos historiográficos ligados à temática central, considerando sobretudo dados relativos à época moderna (séculos XV-XVIII) tendo em conta que, após a extinção de muitas destas instituições, os seus receituários foram (re)interpretados nas casas particulares e deram origem – por exemplo na doçaria – a curiosas (re)criações que hoje são apresentadas como referentes de natureza conventual quando, na realidade, são de inspiração conventual.  A investigação centra-se nos casos da Ordem Beneditina e da Ordem dos Cónegos Regrantes de Santo Agostinho.

Published: October 2023

L’articolo presenta il report di una ricerca sul tema dell’identità (IP) dell’Educatore professionale (EP), identificandone alcuni tratti essenziali che sono stati sottoposti all’opinione dei professionisti. Concettualizzare, individuare una tecnica di rilevamento e misurazione, valutare se esista un’identità professionale diffusa tra i professionisti EP in Italia,sono state le tre domande di ricerca. 

Un campione di 1579 Educatori professionali ha compilato un questionario “on-line” fornendo utili suggerimenti per comprendere i tratti distintivi dell’identità di questo professionista. È stato proposto un modello di IP come variabile unidimensionale, costituito da quattro sottodimensioni, dodici elementi qualificanti e trentadue item d’indagine. La validazione del questionario, con tecniche psicometriche moderne, ha consentito di costruire una scala di misurazione dell’identità professionale dell’Educatore denominata Id-Prof_EP-32.

Successive ricerche condotte anche su differenti professioni con l’utilizzo del medesimo strumento e modello di riferimento potrebbe consentire lo sviluppo di una riflessione condivisa sul tema dell’identità professionale, tratto distintivo e motore di sviluppo delle professioni in ambito riabilitativo.

Authors: Vallefuoco Maria Lorenza , Tozzi Elvira
Published: October 2023

The article aims to describe in a detailed way the logopedic intervention made on a young patient affected by Peroxisome Biogenesis Disorders (PBD). In particular, the focus is the relationship between the two affected senses: sight and hearing. Our patient is a 10-year-old female with an early onset Retinitis Pigmentosa (RP), Sensorineural Hearing Loss (SNHL) and a mild cognitive impairment.
The child has been precociously prothesized with a good prosthetic outcome and underwent both speech therapy and neuro-psychomotor therapy. A stability in her hearingabilities was detected, but the growing visual impairment was accompanied by a deficiency of attention abilities, of visual perception abilities and of visual-motor integration.

Impedance Margin Ratio: a New Metric for Small-Signal System Strength
Authors: Zhu Yue , Green Timothy C. , Zhou Xiaoyao , Li Yitong , Kong Dechao , Gu Yunjie
Published: October 2023

The high and growing penetration of inverter-based resources (IBR) in power systems challenges the way that system strength is assessed. It has been noticed that the standard indicator of system strength, short-circuit ratio (SCR), is not fully effective in anticipating the sub/super-synchronous oscillation phenomena that can arise from interactions of the control system of an IBR and the rest of the system. In this paper, system strength is first viewed from two perspectives, small-signal system strength and large-signal system strength, which is a natural separation considering the markedly different response of an IBR in normal operation and under faults. For assessing the onset of small-signal instability, a new metric for small-signal system strength is proposed and named Impedance Margin Ratio (IMR). IMR is the ratio between the allowed variation of the impedance of an IBR and the original value of the impedance at a particular point of interconnection. IMR is assessed at the oscillatory frequency of the dominant mode or taken as the minimum value across several modes. It is shown that as a localised frequency-domain indicator, IMR can successfully reveal weak points in the system towards various causes of oscillations.
