Authors:   Faculty of Letters & Human Sciences, Department of English Language & Literature, Goldouz Elnaz , Baleghizadeh Sasan
Published: June 2024

This study was conducted to identify Iranian EFL teachers' perceptions regarding the most serious written errors made by young adult EFL learners, along with the most effective types of written corrective feedback to deal with them. Data were collected from 253 Iranian EFL teachers through a questionnaire made by the researchers and were analyzed using descriptive statistics. The results showed that the most serious errors perceived by the teachers were verb form and verb tense, and word order driven by psychological verbs. The most useful feedback types to treat these errors were (a) direct, non-negotiated feedback and (b) indirect, negotiated. The findings contribute to the research concerning the most frequently noticed errors by EFL teachers along with the most frequently employed corrective feedback strategies to address them.
Gender Representation in EFL Textbooks in Basic Education in Mexico
Authors:   Benemérita Universidad Autónoma de Puebla, Sánchez Aguilar Janeth
Published: June 2024

Research on language and gender began in the 1970s with a broad interest, particularly from feminist researchers (Sunderland & Swann, 2016). The relationship between gender and language is of increasing interest to many scholars and researchers due to their bi-directional relationship. That is, according to AydinoÄŸlu (2014) 'gender is reflected by language and language helps to shape gender' (p. 233). This study examines male and female representation in three EFL textbooks used in early elementary grades in public schools in Mexico. To this end, two types of analyses were performed to explore the distribution of males and females in terms of visibility in illustration and photos, and display of male and female occupational roles in the visuals. Findings revealed that there is not a balanced representation of characters in the three textbooks; males were significantly more frequent than female characters in the illustrations. In terms of photos, it was found that both genders were allotted a similar number of appearances Similarly, the results indicated that occupational gender stereotypes occurred in the three textbooks.
Teachers’ Beliefs about Teacher Metamorphosis
Authors:   Farhangian University, Kamali Jaber
Published: June 2024

The advent of postmethod encouraged much debate over the concept amongst researchers from different approaches. One approach was the concept of teacher metamorphosis, which posits that teachers should perform different roles and hence, teacher metamorphosis is considered a possible remedy for certain criticisms of postmethod. Although this metamorphosis is a solution that seems tenable, there remain many questions regarding its practicality. Considering that those who are most directly connected with the concept are teachers, the present study investigates the practicalities of teacher metamorphosis from teachers' perspectives. To this end, ten teachers were selected and interviewed about their beliefs on teacher metamorphosis. Data analysis reveals that almost all the interviewed teachers agreed that there is a need for teacher metamorphosis, although they also agree that there are barriers including financial barriers, respect barriers, time-constraint barriers, and incentive barriers that encourage teachers to resist metamorphosis and that, therefore, needs further consideration.
Multiliteracidad basada en los géneros en ILE. Gramática Sistémica Funcional en práctica para futuros docentes de Educación Primaria
Authors:   Universidad de Valencia, Alcantud-Dí­az Maria
Published: June 2024

This article deals with a case study focused on the students' perceptions regarding a pedagogical intervention aimed at improving communication skills in English (oral and written reception and production). This has been done through a theoretical-methodological proposal, the Bringing Generations Together project, which is an experiential learning model whose objective was to expand the multimodal repertoire based on learning and become able to teach English as a Foreign Language (EFL) within the framework of Genre-Based Multiliteracy (GBM). This project was carried out with 45 fourth-year students of the Primary Education Teaching Degree, specializing in EFL at Universidad de Valencia (Spain). Thus, it was intended that they learn and acquire the skills to teach EFL, design thinking, meaning construction and critical thinking in an integrated way. Likewise, they sought to obtain a theoretical basis to understand the use of language, the pedagogy of genre and the way in which language creates meaning in context. To do this, the students had to create a digital portfolio, the common thread of which was intergenerational education, composed of linked projects of different literary genres: the infographic report, the interview (conversational genre), the film script and the digital story (both part of the narrative genre). As a result, the students worked on advanced skills, understood the SFG in an applied way and obtained the ability to transfer this knowledge to their future Primary Education students

Authors:   Polytechnic of Porto, Cruz Mário
Published: June 2024

In this article we will present a study undertaken in the scope of a Content and Language Integrated Learning project, which was implemented at a local private primary school in the Oporto area, Portugal. This project takes into account the promotion of a teaching and learning process based on the fostering of 21st Century skills, the so-called "creactical skills" i.e., critical thinking and creativity into action (Ohler, 2013) and a global and sustainable awareness. By tackling these, each child has got the chance to develop values and behavior for a sustainable future planet and a positive society transformation based on equality, respect towards diversity, and the finding of solutions to glocal problems. By developing an action research project and following a mixed-method research methodology , we analysed the project's implementation, online questionnaires, and other data including lesson plans, supervision reports/notes, pictures, videos and projects in order to find evidence of practices which foster the "creactical skills". The results show that pupils' critical thinking, creativity, collabora-tion, and cultural awareness skills may have been fostered, but there is still some work to be done regarding other skills mainly due to teachers' approaches which have to change.

Published: June 2024

The article examines and analyzes the peculiarities of the application of immersive technologies in business to increase the effectiveness of marketing communication with the consumer and achieve a higher level of competitiveness and establish relations with potential partners. Businesses can benefit more by introducing new technologies into their operations. However, such technologies require investment. For Ukrainian enterprises, this can become a problem due to the lack of stable profits. The role of immersive technologies in the form of augmented reality (AR) and virtual reality (VR) is determined, which will be a significant incentive for Ukrainian companies in the context of post-war revival, as they can be used to form a new market for the company. The factors that inhibit the use of immersive technologies in marketing are analyzed: high cost, limited access for the audience, the need for training and education, physiological limitations, technical problems, limited parameters for some products, competition with other visual media. Emphasis is placed on the fact that in marketing and sales, efforts should be focused on the use of the following tools: augmented reality in advertising, virtual product fitting, AR assistant in the store, virtual rooms in the store, AR product presentations, VR virtual events and demonstrations. Immersive technologies can help establish communication between the brand and the consumer, as well as establish a partnership. Keywords: business, marketing, immersive technologies, consumers, loyalty, innovation, virtual reality, augmented reality.

Autorización para el Uso Forense del NOMAD en Argentina
Authors: Briem Stamm Alan Diego , Müller Anabel Soledad
Published: June 2024

Los dispositivos portátiles de rayos X se utilizan cada vez con mayor asiduidad para la atención odontológica. Su aplicación introdujo nuevos desafíos inherentes a la seguridad del operador y del paciente, obligando a continuas evaluaciones tendientes a minimizar potenciales riesgos. En la República Argentina, la Ley 17.557 regula el uso para todo tipo de equipos generadores de rayos X, trabajándose actualmente en una normativa específica sobre las unidades dentales portátiles como el NOMADTM. Las principales dudas vinculadas a dicha tecnología residen en los niveles de radiación de fuga y dispersión emanada a través de los blindajes y estructuras plomadas del tubo de rayos X, además del control de la retro dispersión que atraviesa el escudo protector de acrílico plomado adaptado en el extremo final del tubo localizador. Ello podría incidir en la variabilidad de los tiempos de exposición, el peso del equipo, la protección del operador y de terceras personas, además de condiciones no controladas del ambiente laboral, atentando contra el principio ALARA, es decir “tan bajo como sea razonablemente alcanzable”. En virtud de lo expresado, y mediante un pormenorizado análisis técnico-científico realizado en la Facultad de Odontología de la Universidad de Buenos Aires y en el Centro Asistencial “Buenos Aires” de Gendarmería Nacional, desde el Área Técnica Radiofísica Sanitaria del Ministerio de Salud de la Nación se determinó que el empleo de dispositivos portátiles de rayos X como el NOMADTM sea contextualizado exclusivamente a eventos periciales sobre cadáveres y restos óseos, respetando las normas de seguridad y protección emanadas por la legislación vigente.
Nexus of Corporate Governance, Financial Reporting Quality and Investment Efficiency
Authors: Khan Irfan Ullah , Ahmed Shakeel , Iqbal Muhammad , Khan Usman Shaukat
Published: June 2024

This paper examines the relationship between corporate governance, financial reporting quality, and investment efficiency using data from 207 non-financial firms listed on the Pakistan Stock Exchange (PSX) for a period of 9 years from 2008 to 2016. Since the Pakistan Corporate Governance Code was revised in 2012, therefore consistent with previous studies, the effect of the promulgation of the new corporate governance code on financial reporting quality is also analyzed. Thus, using the GMM model, the results of the study show that the Corporate Governance Code 2012 improves the quality of financial reporting. Owners of family firms confiscate the wealth of minority shareholders by deteriorating the quality of financial reports. Independent directors of the board and independent directors of the audit committee effectively monitor the financial reporting process. Family ownership, board independence and audit committee independence interact with the code in affecting financial reporting quality and substitute or complement each other. Inefficient investments decrease financial reporting quality. Furthermore, the new governance code has an incremental effect on the relationship between investment inefficiency and financial reporting quality.

Authors: Alqahtani Abdulfattah , Alajam Ramzi , Liu Wen
Published: June 2024

Stroke is the leading cause of long-term disability worldwide. After stroke, people commonly experience additional cardiovascular disease, cognitive declination, sensorimotor disability, pulmonary dysfunction, psychological problems, and bone health declinations. In stroke rehabilitation research, most of previous studies focused on recovery of sensorimotor function, with few studies examined outcomes in cardiovascular, cardiopulmonary, and bone health, particularly in non-ambulatory individuals who are at even higher risk of secondary complications. In this narrative review, we reviewed the health benefits of aerobic walking exercise on cardiovascular, pulmonary, and bone health in non-ambulatory stroke survivors. We started with a review of health issues in cardiopulmonary system and bones in non-ambulatory stroke survivors. We then reviewed the current state of clinical research findings of aerobic walking exercise in non-ambulatory stroke survivors. We reviewed the aerobic exercise guidelines for non-ambulatory stroke survivors and whether walking exercise was recommended for them. Then, we investigated the exercise position (standing vs. sitting) to see which exercise position would be recommended to improve or at least maintain the health of cardiopulmonary and bone in non-ambulatory stroke survivors. We finally reviewed the walking assistive devices that makes walking exercise feasible for non-ambulatory stroke survivors.

Phonation threshold pressure in inspiratory vs expiratory phonation
Authors: Lucero Jorge
Published: June 2024

Inspiratory or reverse phonation refers to the production of voice when air is inhaled from the mouth and nostrils into the lungs. This way of phonation occurs naturally during laughter, sighs, and crying [1]. It has also been used to achieve special vocal effects by singers, shamans, and ventriloquists, and is common in the vocalizations of other mammals and birds. Furthermore, it is a useful treatment exercise in voice therapy for several voice disorders [2]. However, despite its relevance, few physical studies of inspiratory phonation have been conducted, and its underlying physics still needs further clarification.

Energygame - Ett dynamiskt lärandeperspektiv med inriktning på ökad motivation i en spelifierande lärandeprocess inom teknikprogrammet
Authors: Westman Lars
Published: June 2024

Med motivation och lärdom vågar man både utmana och pröva nytt, vilket var syftet med mitt utvecklingsarbete. I skolan undervisas elever som upplever att de inte är särskilt motiverade att genomföra vissa skolarbeten, och somliga elever kan tycka att det finns andra aktiviteter som är mer lockande. Är lektionsuppläggen inte tillräckligt stimulerande kan eleverna känna att de inte blir engagerade och tappa motivationen, vilket kan leda till att de inte tar till sig kunskapen fullt ut. Ett spelifierat lektionsupplägg handlar om att öka förutsättningarna för hur man kan fånga elevers intresse, nyfikenhet och motivation för lärande i en teoretisk undervisning på ett roligt sätt, för ett livslångt lärande. Den undervisning som beskrivs behandlade Sveriges energisystems varierande energikällor för energiproduktion i frågor om hållbar utveckling. Utvecklingsarbetet planerades som ett motivationsinspirerande spelifierat lektionsupplägg med inslag av spel, ett rollspel som kallas Energygame. Detta spelifierade lektionsupplägg syftade till att både förstärka motivationen och skapa fortsatt inspiration till ytterligare lärande. Detta spelifierade arbetssätt lämpar sig i varierande skolformer och vänder sig till både yrkeslärare och ämneslärare.
Undervisningsstrategier i rörelse – tibetanska lärares arbete med argumentationsteknik i olika skolämnen
Authors: Wejrum Marie , Byman Frisén Liliann , Johansson Annelie K. , Olin-Scheller Christina , Grönvall Fransson Camilla
Published: June 2024

Skolans demokratiuppdrag innefattar att elever utvecklar ett kritiskt reflekterande förhållningssätt till texter. I denna artikel belyser vi utifrån ett critical literacy-perspektiv hur detta kritiska förhållningssätt kan förstås i relation till ett inslag i tibetanska skolor – den tibetanska argumentationstekniken. Tekniken är utvecklad inom en religiös och filosofisk kontext, men implementeras nu i sekulära skolor i ambition att stärka elevernas självförtroende och tänkande. Syftet med denna artikel är att fördjupa kunskapen om hur den tibetanska argumentationstekniken gestaltas i undervisning i exiltibetanska skolor i Dharamsala, Indien. Ett specifikt fokus riktas mot hur argumentationstekniken kan förstås utifrån ett perspektiv där utvecklandet av en kritisk reflexion ses som en nödvändig del av utbildningsuppdraget. Det empiriska materialet till artikeln består av observationer vid skolbesök och intervjuer med lärare. Våra resultat pekar på att lärarna, när de använder argumentationstekniken som en del av undervisningen, upplever att elever utvecklar sin språkförmåga och ämnesförståelse och dessutom stärker sitt självförtroende. Tillgången till verktyget verkar ge eleverna tillgång till språk och kunskaper som utvecklar deras förmåga till logiskt tänkande och att själva uttrycka sig, vilket i sin tur ger dem större makt att påverka sina framtida möjligheter. Resultaten pekar också på att argumentationstekniken lämpar sig särskilt väl för vissa ämnen och särskilda ämnesinnehåll.
Attentional modulation of secondary somatosensory and visual thalamus of mice
Authors: Petty Gordon H , Bruno Randy M
Published: June 2024

Each sensory modality has its own primary and secondary thalamic nuclei. While the primary thalamic nuclei are well understood to relay sensory information from the periphery to the cortex, the role of secondary sensory nuclei is elusive. One hypothesis has been that secondary nuclei may support feature-based attention. If this is true, one would also expect the activity in different nuclei to reflect the degree to which modalities are or are not behaviorally relevant in a task. We trained head-fixed mice to attend to one sensory modality while ignoring a second modality, namely to attend to touch and ignore vision, or vice versa. Arrays were used to record simultaneously from secondary somatosensory thalamus (POm) and secondary visual thalamus (LP). In mice trained to respond to tactile stimuli and ignore visual stimuli, POm was robustly activated by touch and largely unresponsive to visual stimuli. A different pattern was observed when mice were trained to respond to visual stimuli and ignore touch, with POm now more robustly activated during visual trials. This POm activity was not explained by differences in movements (i.e., whisking, licking, pupil dilation) resulting from the two tasks. Post hoc histological reconstruction of array tracks through POm revealed that subregions varied in their degree of plasticity. LP exhibited similar phenomena. We conclude that behavioral training reshapes activity in secondary thalamic nuclei. Secondary nuclei may respond to behaviorally relevant, reward-predicting stimuli regardless of stimulus modality.
Deep learning-based dimensional emotion recognition for conversational agent-based cognitive behavioral therapy
Authors: Striegl Julian , Richter Jordan Wenzel , Grossmann Leoni , Bråstad Björn , Gotthardt Marie , Rück Christian , Wallert John , Loitsch Claudia
Published: June 2024

Internet-based cognitive behavioral therapy (iCBT) offers a scalable, cost-effective, accessible, and low-threshold form of psychotherapy. Recent advancements explored the use of conversational agents such as chatbots and voice assistants to enhance the delivery of iCBT. These agents can deliver iCBT-based exercises, recognize and track emotional states, assess therapy progress, convey empathy, and potentially predict long-term therapy outcome. However, existing systems predominantly utilize categorical approaches for emotional modeling, which can oversimplify the complexity of human emotional states. To address this, we developed a transformer-based model for dimensional text-based emotion recognition, fine-tuned with a novel, comprehensive dimensional emotion dataset comprising 75,503 samples. This model significantly outperforms existing state-of-the-art models in detecting the dimensions of valence, arousal, and dominance, achieving a Pearson correlation coefficient of r = 0.90, r = 0.77, and r = 0.64, respectively. Furthermore, a feasibility study involving 20 participants confirmed the model’s technical effectiveness and its usability, acceptance, and empathic understanding in a conversational agent-based iCBT setting, marking a substantial improvement in personalized and effective therapy experiences.
Comparative evaluation of machine learning algorithms for phishing site detection
Authors: Almujahid Noura Fahad , Haq Mohd Anul , Alshehri Mohammed
Published: June 2024

The advent of Internet technologies has resulted in the proliferation of electronic trading and the use of the Internet for electronic transactions, leading to a rise in unauthorized access to sensitive user information and the depletion of resources for enterprises. As a consequence, there has been a marked increase in phishing, which is now considered one of the most common types of online theft. Phishing attacks are typically directed towards obtaining confidential information, such as login credentials for online banking platforms and sensitive systems. The primary objective of such attacks is to acquire specific personal information to either use for financial gain or commit identity theft. Recent studies have been conducted to combat phishing attacks by examining domain characteristics such as website addresses, content on websites, and combinations of both approaches for the website and its source code. However, businesses require more effective anti-phishing technologies to identify phishing URLs and safeguard their users. The present research aims to evaluate the effectiveness of eight machine learning (ML) and deep learning (DL) algorithms, including support vector machine (SVM), k-nearest neighbors (KNN), random forest (RF), Decision Tree (DT), Extreme Gradient Boosting (XGBoost), logistic regression (LR), convolutional neural network (CNN), and DL model and assess their performances in identifying phishing. This study utilizes two real datasets, Mendeley and UCI, employing performance metrics such as accuracy, precision, recall, false positive rate (FPR), and F-1 score. Notably, CNN exhibits superior accuracy, emphasizing its efficacy. Contributions include using purpose-specific datasets, meticulous feature engineering, introducing SMOTE for class imbalance, incorporating the novel CNN model, and rigorous hyperparameter tuning. The study demonstrates consistent model performance across both datasets, highlighting stability and reliability.
Automated sentiment analysis of visually impaired students’ audio feedback in virtual learning environments
Authors: Elbourhamy Doaa Mohamed
Published: June 2024

This research introduces an innovative intelligent model developed for predicting and analyzing sentiment responses regarding audio feedback from students with visual impairments in a virtual learning environment. Sentiment is divided into five types: high positive, positive, neutral, negative, and high negative. The model sources data from post-COVID-19 outbreak educational platforms (Microsoft Teams) and offers automated evaluation and visualization of audio feedback, which enhances students’ performances. It also offers better insight into the sentiment scenarios of e-learning visually impaired students to educators. The sentiment responses from the assessment to point out deficiencies in computer literacy and forecast performance were pretty successful with the support vector machine (SVM) and artificial neural network (ANN) algorithms. The model performed well in predicting student performance using ANN algorithms on structured and unstructured data, especially by the 9th week against unstructured data only. In general, the research findings provide an inclusive policy implication that ought to be followed to provide education to students with a visual impairment and the role of technology in enhancing the learning experience for these students.
MCV-UNet: a modified convolution & transformer hybrid encoder-decoder network with multi-scale information fusion for ultrasound image semantic segmentation
Authors: Xu Zihong , Wang Ziyang
Published: June 2024

In recent years, the growing importance of accurate semantic segmentation in ultrasound images has led to numerous advances in deep learning-based techniques. In this article, we introduce a novel hybrid network that synergistically combines convolutional neural networks (CNN) and Vision Transformers (ViT) for ultrasound image semantic segmentation. Our primary contribution is the incorporation of multi-scale CNN in both the encoder and decoder stages, enhancing feature learning capabilities across multiple scales. Further, the bottleneck of the network leverages the ViT to capture long-range high-dimension spatial dependencies, a critical factor often overlooked in conventional CNN-based approaches. We conducted extensive experiments using a public benchmark ultrasound nerve segmentation dataset. Our proposed method was benchmarked against 17 existing baseline methods, and the results underscored its superiority, as it outperformed all competing methods including a 4.6% improvement of Dice compared against TransUNet, 13.0% improvement of Dice against Attention UNet, 10.5% improvement of precision compared against UNet. This research offers significant potential for real-world applications in medical imaging, demonstrating the power of blending CNN and ViT in a unified framework.
Optimization of polysaccharide conditions and analysis of antioxidant capacity in the co-culture of Sanghuangporus vaninii and Pleurotus sapidus
Authors: Lu Yuantian , Liu Di
Published: June 2024

Fungal polysaccharides are commonly utilized in the food industry and biomedical fields as a natural and safe immune modulator. Co-culturing is a valuable method for enhancing the production of secondary metabolites. This study used intracellular polysaccharide (IPS) content as a screening index, co-culturing seven different fungi with Sanghuangporus vaninii. The seed pre-culture liquid culture time was selected through screening, and conditions were assessed using single factor experimentation, a Plackett-Burman (PB) design, and response surface methodology (RSM) optimization. RSM optimization was conducted, leading to the measurement of antioxidant capacity. Results indicated that the co-culture of S. vaninii and Pleurotus sapidus exhibited the most effective outcome. Specifically, pre-culturing S. vaninii and P. sapidus seed cultures for 2 days and 0 days, respectively, followed by co-culturing, significantly increased IPS content compared to single-strain culturing. Further optimization of co-culture conditions revealed that yeast extract concentration, liquid volume, and S. vaninii inoculum ratio notably influenced IPS content in the order of yeast extract concentration > liquid volume > S. vaninii inoculum ratio. Under the optimal conditions, IPS content reached 69.9626 mg/g, a 17.04% increase from pre-optimization co-culture conditions. Antioxidant capacity testing demonstrated that co-cultured IPS exhibited greater scavenging abilities for DPPH and ABTS free radicals compared to single strain cultures. These findings highlight the potential of co-culturing S. vaninii and P. sapidus to enhance IPS content and improve antioxidant capacity, presenting an effective strategy for increasing fungal polysaccharide production.

In this article, with a view to improving the efficiency of photovoltaic cells, and given the promising yields of silicon heterojunction photovoltaic cells, we have, using a silicon heterojunction cell (a-Si:H/c-Si) doped with (n+p) , studied the contribution of excitons to the internal quantum efficiency of charge carriers.
We then developed a detailed explanation of the energy conversion phenomena, based on an exciton-exciton annihilation process, which allows the electrons of quasiparticles to retain some of their energy. We used a numerical method for solving the charge carrier transport equations and carried out some additional calculations, which enabled us to obtain some results.
These results then enabled us to study the influence of the annihilation lifetime on the charge carrier photo-current density, leading to internal charge carrier quantum yields of between 29.29768% and 77.8525%.

The proposed development at Beaverbank Place, Canonmills, Edinburgh led to the excavation of the remains of the 19th-century Beaverbank Tannery. Accompanying historical research allowed the history of the ownership and tenancies of the buildings and various businesses to be traced from 1807 to 1959. This included the early 19th-century Clark’s Mill linen bleachers and the 1868 tannery built by the Johnston family and later leased by family firms of the Pringles and Walkers. A period of abandonment between 1913 and 1915 was followed by the repurposing of the building as a sawmill and cooperage. Part of the site changed again to become a motor garage in 1928.
The remains can be matched well with historic map evidence and appear to relate predominantly to the late 19th-century tannery structures. Remains were found of approximately 100 tanning pits set out in a grid pattern, with further features related to drainage, paving and other structures. Very little environmental or artefactual evidence was recovered to shed light on specific practices, materials used or materials produced.
There were also scant structural remains that could be related to the earlier linen bleachers and to the later motor garage.
