Authors: Wang Xiaoxia , Wang Youli , Luo Jianjun , Wang Lipeng , Guo Liye , Zhu Xinxin
Published: September 2023

Background: One of the common adverse reactions in patients with pressure ulcers (PU) is sepsis, which is mainly related to microbial infections caused by pathogenic organisms. The activation of nuclear factor kappa-B (NF-κB) frequently occurs in conjunction with pathogenic microbial infections. Proline-serine-threonine-phosphatase-interacting protein 2 (PSTPIP2) is closely related to inflammatory disorders. The role and mechanism of PSTPIP2 in sepsis because of pressure ulcers is unclear. In this study, we discovered that PSTPIP2 was lowly expressed in peripheral blood of patients with sepsis induced by pressure ulcers.
Methods: Peripheral blood was collected from 20 patients with sepsis due to pressure ulcers and 10 healthy controls, and the expression of PSTPIP2 in peripheral blood was discovered by polymerase chain reaction and Western blot analysis. Information on the clinical characteristics of patients was summarized, and the expression data of PSTPIP2 were correlated with the patients’ acute physiology and chronic health evaluation (APACHE) II score, sequential organ failure assessment (SOFA) score, and C-reactive protein (CRP) and procalcitonin (PCT) scores by Spearman’s correlation analysis. One of the main mediators of Gram-negative sepsis is lipopolysaccharide (LPS). In order to establish an in vitro sepsis model, THP-1 cells were treated with LPS, and the cells were transfected with PSTPIP2. Contents of interleukin 6 (IL-6), interleukin 1β (IL-1β), and tumor necrosis factor-α (TNF-α) in each group of cells were detected by enzyme-linked-immunosorbent serologic assay, and NF-κB-related proteins were detected by Western blot analysis.
Results: When compared to healthy controls, the peripheral blood of patients with pressure sepsis had lower PSTPIP2 expression, which had a negative correlation with the APACHE II, SOFA, CRP, and PCT scores. LPS-induced THP-1 cells expressed less PSTPIP2 than the untreated control cells, and PSTPIP2 transfection decreased IL-6, IL-1β, and TNF-α levels and inhibited the activation of NF-κB pathway.
Conclusion: PSTPIP2 is associated with disease severity in patients with pressure ulcer sepsis and has anti-inflammatory effects.

Background: Hypersensitivity reactions (HSRs) to nonsteroidal anti-inflammatory drugs (NSAIDs) are a significant clinical issue. Several classifications have been proposed to categorize these reactions, including the current European Academy of Allergy and Clinical Immunology/ European Network for Drug Allergy (EAACI/ENDA) classification. This study aimed to evaluate the applicability of this classification in a real-world clinical setting.
Methods: We conducted a national multicenter study involving patients from nine hospitals in four major urban centers in Turkey. All patients had a suggestive clinical history of hypersen-sitivity reactions to NSAIDs. Researchers collected data using a structured form and classified reactions based on the EAACI/ENDA classification. Oral provocation tests with several NSAIDs were performed using a single-blind challenge per EAACI/ENDA guidelines.
Results: Our retrospective study included 966 adult patients with a history of hypersensitivity to NSAIDs. The most common triggers were Acetylsalicylic Acid (ASA), paracetamol, and metamizole. The most prevalent acute NSAID hypersensitivity group was NSAID-induced urticaria/angioedema (NIUA) (34.3%). However, 17.3% of patients did not fit neatly into the current EAACI/ENDA classification. Notably, patients with underlying asthma or allergic rhinoconjunctivitis exhibited unusual reactions, such as urticaria and/or angioedema induced by multiple chemical groups of NSAIDs, blended mixed reactions, and isolated periorbital angioedema in response to multiple chemical groups of NSAIDs.
Conclusions: While the EAACI/ENDA classification system stratifies NSAID-induced hypersensitivity reactions into five distinct endotypes or phenotypes, it may not fully capture the diversity of these reactions. Our findings suggest a need for further research to refine this classification system and better accommodate patients with atypical presentations.

Introduction: Serum vitamin D levels depend on sunlight, diet, and other factors. Objective: We aimed to determine serum vitamin D levels and evaluate their relationship with anthropometric indicators and lifestyle habits in apparently healthy volunteers. Materials and Methods: In this cross-sectional study (n=75), socio-demographic, anthropometric, and lifestyle habit-related data were collected. Serum vitamin D levels were determined with high performance liquid chromatography, food intake was measured by semiquantitative frequency and nutritional status was assessed by anthropometry. Chi-square test and also principal component analysis were used to analyze the relationship between some variables and vitamin D status. Spearman’s test was used to determine correlations between quantitative variables. Results: 73% were women and 61% belonged to medium socio-economic level. Median vitamin D intake was 137 (83.1–227.3) IU/day. Based on body mass index (BMI), 44% individuals had overweight/obesity. The 68% exhibited deficient/insufficient vitamin D levels (Hypovitaminosis D). BMI classification and waist circumference (CW) were not related with vitamin D status; however, activities with higher sun exposure were highly related (p = 0.013). Sun exposure time explained variation in component 2 (16.60%), where most of the individuals with normal level were grouped. Sun exposure time was positively correlated with vitamin D status (r = 0.263; p = 0.023). Discussion: Excess weight and abdominal obesity are not always associated with hypovitaminosis D. Conclusions: The majority of individuals showed hypovitaminosis D but their status was not related with anthropometric indicators. A Sun exposure time was the only factor positively correlated with vitamin D status.

Post-Brexit Recognition and Enforcement of Judgements: Problems and Solutions
Authors: Bruce Matthew
Published: September 2023

There is a need for the UK and EU to continue mutual assistance in criminal matters. As a Member State, mutual assistance in criminal matters between the UK and EU was primarily governed by an EU convention. This convention builds on existing Council of Europe conventions on mutual criminal assistance. With the UK now outside the EU’s data protection architecture, this may pose a significant hurdle for future cooperation. This article critically analyses the need for a data adequacy decision from the EU for the UK to engage in mutual assistance in criminal matters post-Brexit. To reach a conclusion, the article is set out over three substantive areas considering: mutual assistance and data protection law as it applies to EU Member States; the law underpinning adequacy decisions; and future legal developments post-Brexit. Specific examples of data transfers and the effect of the Trade and Cooperation Agreement are compared and contrasted to adequacy decisions. While provisions of the Trade and Cooperation Agreement and EU Law Enforcement Directive provide some assurances, the article recommends that a data adequacy decision made under the Directive is pursued.

Published: September 2023

ABSTRACT: This work aims to investigate the work and professional development of Brazilian teachers during emergency remote teaching in the COVID-19 pandemic, considering aspects such as working conditions, teaching-learning, and mental health. A sample of 364 basic education teachers in Brazil was assessed using self-report instruments considering sociodemographic data, working conditions, aspects related to teaching work and teaching learning (activities, knowledge and teacher education), mental health, and meaning in life. The results showed that changes in teaching work occur amid the absence or limited experience of most teachers with online teaching and/or the use of digital technology, in addition to the lack of adequate support and working conditions. The main tasks were mediated by technology, and didactic knowledge played a fundamental role in this context. The education offered to teachers by the institutions was largely insufficient, causing the need for complementary (self)education. Experiential knowledge has been shown to be fundamental in teaching and learning. Finally, mental health was shown to play a crucial role in this professional development process, in addition to demonstrating a positive correlation with the presence of meaning in life. The implications for the professional development of teachers are discussed.

Resumo Objetivos: analisar o estado nutricional e a tendência temporal da cobertura de adolescentes brasileiros acompanhados no Sistema de Vigilância Alimentar e Nutricional no período de 2008-2019. Métodos: estudo ecológico de séries temporais com dados do SISVAN coletados no período de 2008 a 2019 com 45.869.266 de registos. Foram coletados dados de índice de massa corporal e calculadas as coberturas dos registros dos adolescentes acompanhados pelo sistema. Estimou-se a percentagem da variação anual da cobertura e estado nutricional pela regressão de Prais-Winsten, com nível de significância de 5%. Resultados: observa-se crescimento da prevalência de obesidade entre 2008 a 2019, nesse período a magreza manteve-se estável no Brasil. A cobertura nacional evoluiu de 9,3% em 2008 para 19,6% em 2019, com variação anual de 9% e tendência de aumento estatisticamente significativa. No Brasil, a obesidade nessa faixa etária apresentou um aumento entre os anos de 2008 e 2019, com uma variação anual de 8,7% (IC95%= 7,8-9,6). Conclusão: modificações observadas no estado nutricional sugerem a ocorrência da transição nutricional na população de adolescentes. O percentual de cobertura disponível no sistema tem potencial de crescimento, entretanto, o atual cenário impacta em possível análise insuficiente para subsidiar a elaboração e reorientação de políticas públicas.

Abstract Equipment replacement is a definitive and relevant engineering decision. The aim of this work was to identify and organize the mathematical optimization proposals and solution search techniques that have contributed toward solving this problem. As a result, we classified the bibliographic materials we identified into seven distinct types of approaches. The work also provides an integrative overview of the level of complementarity of the categories we identified. The network visualization approach represented about 57% of the selected works and is still in use today. Nonetheless, since 2000 other approaches, such as fuzzy logic, real options, and machine learning have increased by 40% and become relevant current trends.

ABSTRACT Aiming at a more sustainable food production, the reuse of effluent from fish farming in hydroponics can be a viable option. Thus, the objective of present study was to evaluate the effects of the use of effluent from fish farming on the development of ‘Folha Larga’ watercress and the possibility of reducing the use of fertilizer in a hydroponic system. The assay was carried out in a greenhouse from October 2021 to February 2022 (two cycles). The treatments were distributed in randomized blocks, with four replications, with split plots, consisting of two times of recirculation of the solution in the plots (T1 = 15 min operating by 15 min off and T2 = 15 min operating by 30 min off) and five solutions, in the subplots, obtained by mixing different proportions (0, 25, 50, 75, and 100%) of nutrient solution and effluent from fish farming. The variables analyzed were: plant height, number of leaflets, leaf area, SPAD index, fresh and dry weight of the aerial part and roots. The use of effluent from fish farming reduces the amount of fertilizers for the yield of ‘Folha Larga’ watercress. Nutrient solution recirculation time of 15 minutes is suitable for hydroponic watercress.

Resumo O objetivo deste artigo é analisar a configuração dos recursos tangíveis e das habilidades humanas de big data, diante das pressões institucionais, na capacidade de análise de big data em empresas brasileiras. A inovação influencia o ambiente em que as empresas estão inseridas, aumentando as incertezas, resultando em modificações comportamentais dos atores sociais. Em resposta aos esforços individuais para lidar com as incertezas e restrições de forma racional emerge a homogeneização das organizações. No entanto, as pressões institucionais que influenciam a configuração de recursos específicos ainda não são totalmente entendidas pela literatura. Considera-se a replicação do estudo de Dubey (2019b), entendendo a tecnologia big data como uma inovação que tem causado mudanças no contexto social, assim, busca-se compreender a configuração dos recursos organizacionais de big data nas empresas brasileiras para o desenvolvimento da capacidade de ABD, devido às pressões institucionais. O estudo possibilita compreender como as pressões institucionais configuram a capacidade de ABD, podendo assim subsidiar decisões de alocação de investimento em tecnologia de dados ou aprimoramento de habilidades técnicas de gerenciais da equipe de business intelligence. O estudo trouxe a conhecimento a resposta ambiental, resultante da inovação tecnológica de big data, das empresas brasileiras. Isso demonstra que as organizações que aderiram a tecnologia big data selecionam seus recursos diante de diferentes pressões, a fim de desenvolver a capacidade de análise de big data. Esta pesquisa possui caráter descritivo e quantitativo e sua operacionalização ocorreu por uma survey. A população pesquisada consiste em empresas brasileiras que usam tecnologia com grande volume de dados estruturados e/ou não estruturados, para a geração de resultados e insights, que auxiliam na tomada de decisão. Os participantes da pesquisa foram colaboradores de empresas brasileiras que apresentem funções relacionadas ao desenvolvimento da capacidade de análise de big data, localizados por meio da plataforma LinkedIn. Foram obtidas 136 respostas válidas. Para testar as hipóteses se usou a técnica de Modelagem de Equações Estruturais empregando o software Smartspls v. 3.2.3. Este estudo contribui trazendo a compreensão do comportamento organizacional diante das pressões institucionais (coercitiva, normativa e mimética) na seleção dos recursos tangíveis e habilidades humanas de big data para o desenvolvimento da capacidade de ABD, fundamentado na Teoria Baseada em Recursos. Observa-se que a configuração da capacidade de ABD é influenciada por recursos tangíveis e habilidades humanas. Os recursos tangíveis são selecionados devido a pressões formais, condições competitivas e por imitação de padrões existentes no mercado. Enquanto, as habilidades humanas requeridas, são impactadas, por meio da legitimação e redes profissionais dos tomadores de decisão.

Published: September 2023

Resumen Este manuscrito tiene como propósito examinar el papel de las condiciones familiares en el desempeño laboral de mujeres migradas - desde los flujos Sur-Norte - empleadas de hogar y cuidadoras en España, durante la crisis económica iniciada en 2007 y los años inmediatamente posteriores. A partir de la realización de 31 entrevistas en profundidad, se explora las intersecciones entre el ciclo de vida familiar, la organización económica de éste y la integración ocupacional de trabajadoras con acceso limitado a todo tipo de recursos. Los resultados plantean que, frente a explicaciones fundamentadas en las condiciones de asentamiento y capital humano migrante, la integración ocupacional de estas mujeres se sustenta en el disfuncional y conflictivo equilibrio por satisfacer las demandas de cuidado familiar y las demandas de subsistencia material, lo cual, ante la carencia de soportes comunitarios e institucionales de cuidado, lleva aparejadas experiencias de servidumbre, pobreza y exclusión social.
Gigante com Pés de Barro: O Trabalho Rural como Elo Frágil do Agronegócio em Tempos de Reformas Trabalhistas
Authors: Picolotto Everton Lazzaretti
Published: September 2023

Resumo O artigo analisa as mudanças promovidas pela Reforma Trabalhista de 2017 nas relações de trabalho rurais e nas práticas sindicais. Os direitos trabalhistas e a sindicalização dos trabalhadores rurais foram regulamentados nos anos de 1960 e receberam maior aprimoramento nas décadas seguintes, notadamente na Constituição de 1988. O artigo parte da análise de textos das Convenções Coletivas de Trabalho (CCT) e outros documentos, além de entrevistas com lideranças sindicais em quatro áreas do agronegócio gaúcho. As reformas reduziram o poder do Estado na definição das relações de trabalho, flexibilizaram os contratos e jornadas, os sindicatos perderam parte de seu poder na intermediação das relações de trabalho e das suas receitas, ao passo que aumentou a importância do acertado nas CCT, inclusive, se sobrepondo à lei. Estas mudanças são significativas para o trabalho rural e os sindicatos em áreas de ponta do agronegócio e ainda precisam ser melhor compreendidas pela academia.
A Review on Implantable Neuroelectrodes

Published: September 2023

The efficacy of every neuromodulation modality depends upon the characteristics of the electrodes used to stimulate the chosen target. The geometrical, chemical, mechanical and physical configuration of electrodes used in neurostimulation affects several performance attributes like stimulation efficiency, selectivity, tissue response, etc. The efficiency of stimulation in relation to electrode impedance is influenced by the electrode material and/or its geometry. The nature of the electrode material determines the charge transfer across the electrode-tissue interface, which also relates to neuronal tissue damage. Electrode morphology or configuration pattern can facilitate the modulation of extracellular electric field (field shaping). This enables selective activation of neurons and minimizes side effects. Biocompatibility and biostability of the electrode materials or electrode coating have a role in glial formation and tissue damage. Mechanical and electrochemical stability (corrosion resistance) determines the long-term efficacy of any neuromodulation technique. Here, a review of electrodes typically used for implantable neuromodulation is discussed. Factors affecting the performance of electrodes like stimulation efficiency, selectivity and tissue responses to the electrode-tissue interface are discussed. Technological advancements to improve electrode characteristics are also included.

Published: September 2023

The experimental study of adiabatic two-phase gas-liquid flow in an extremely small gap microchannel with a height
of 10 μm and width of 10 mm has been carried out. Color schlieren visualization allows the registering of typical flow patterns: Jet-Droplet, Jet-Churn, Churn, and Droplet-Annular. Flow patterns have been described and flow pattern maps have been created and compared with those of gap microchannels of higher sizes. The interference pattern of thin liquid films makes it possible to distinguish two mechanisms of their creation. New features and flow patterns are revealed that were not observed in larger gap microchannels. Liquid droplet sizes have been studied. It is shown statistically that with an increase of superficial liquid or gas velocity, the droplet size distribution is shifted towards smaller sizes.
DIAGNOSIS OF KIDNEY CYST, TUMOR AND STONE FROM CT SCAN IMAGESUSING FEATURE FUSION HYPERGRAPH CONVOLUTIONAL NEURAL NETWORK (F2HCN2)

Published: September 2023

The development of a computational tool to diagnose kidney disorders in their early stages is necessary due to the rise in chronic kidney diseases (CKDs) and the global shortage of nephrologists. The three common renal disorders covered in this study are kidney stones, cysts, and tumors. Early diagnosis of these diseases from the computed tomography (CT) images is a challenging task. Yet, present graph convolutional neural network (GCNN) approaches have the issue of overdependence on the adjacency matrix. Moreover, compared to deep convolutional neural network (CNN) models, a single modal feature results in low accuracy and robustness. In this paper, we proposed the feature fusion hypergraph CNN (F2HCN2) to accurately diagnose kidney diseases in the early stage based on CT scan images. The discriminative features of the images are extracted using DarkNet19 and residual features are extracted using ResNet50. The extracted features are classified using feature fusion hypergraph CNN. The proposed model is trained with 12,446 CT whole urogram and abdomen images. The hypergraph representation learning is performed to train the network with the fused features. Deep learning metrics including accuracy, F1 score (F1), recall, positive predictive value (PPV), receiver operating characteristic curve, and area under curve (AUC) are used to validate the proposed model. It outperforms compared to other state-of-the-art algorithms with accuracy of 99.71%. The proposed F2HCN2 is a robust computer-aided tool for the early diagnosis of kidney diseases. It will assist the radiologist for better prognosis for kidney related abnormalities.

Authors: Gholipour Adham , Davoodi Mohammad-Reza , Yousefpour Hossein
Published: September 2023

Many arch bridges have been built in near-fault regions around the world and may be affected by fling step, which is the permanent ground displacement caused by the long-period pulse within the frequency content of an earthquake. This study investigates the effect of fling step on reinforced concrete deck-type arch bridges with short to medium spans. Three-dimensional non-linear models of three existing reinforced concrete arch bridges in Iran, with span lengths of 23, 35 and 60 m, were developed. The structures were subjected to seven near-fault earthquakes in longitudinal and transverse directions, once with the fling-step pulse included and once with it removed. The results showed that fling step has a noticeable effect on the seismic response indicators investigated, but may increase or decrease the seismic demand. The maximum curvature in the presence of fling step in relation to that without fling step ranged between 0.54 and 2.06. Unseating in the longitudinal direction was most sensitive to the fling step, and showed a more than 200% increase in some cases. Effects of the fling step were correlated with the ratio of the period of the fundamental mode of vibration of the structure to that of the fling-step pulse.

Abstract : This study was designed to offer an online professional development opportunity, "Summer Multicultural and Interdisciplinary Learning for Engineering (SMILE) in Transportation," for future elementary STEM teachers and measure its effects on their teaching. As the student population grows more diverse, schools face more significant challenges in delivering practical instructions on "transportation" to the diverse student population, including minority students who speak English as a second language. SMILE in Transportation provided future science teachers with an opportunity to interact with cultural professionals in Transportation who were experts in Transportation, had their cultural backgrounds, and presented transportation systems through their cultures. The cultural professionals in Transportation involved inter-disciplinarily professionals not only on the college campus but also from the communities. SMILE in Transportation was a novel approach to increase the knowledge of future science teachers in Transportation and to develop a unique teaching methodology that incorporates the backgrounds of culturally and linguistically diverse students into teaching engineering of Transportation. The datacollected from the pre-and the post-surveys of the participants' science affinities & cultural competency (teaching efficacy, cultural competency, personal interest, & cultural IQ), science knowledge tests, and the qualitative survey at the end of the project were used to improve future teachers' understanding of Transportation and other cultures and their skills in developing culturally- responsive instructions to teach Transportation, as well as to update SMILE workshop for future sessions. Keywords: interdisciplinary; minority students; multicultural; Transportation; professional development.

CROSS FLOW IN THE WELL

Published: September 2023

The article considers the problem of pressure fields in a system consisting of two perforated reservoirs penetrated by one well, providing a hydrodynamic connection between them. One-dimensional equations of piezoconductivity in radial geometry are used to describe the pressure fields in the reservoirs. The hydrodynamic connection between the layers through the well is given by an integro-differential equation obtained on the basis of mass balance and Darcy's law.It is assumed that there are no pressure disturbances at the initial moment of time and in the parts of the reservoirs remote from the well. At the boundaries between the well and the reservoirs for the time t>0, the conditions for equal pressures are set. Exact analytical solutions describing pressure fields in reservoirs and wells are constructed in the Laplace–Carson image space. Computational experiments for modeling pressure fields and flows were carried out using the Stehfestand den Iseger algorithms, which made it possible to eliminate the time-consuming procedure of transition to the original space. The joint use of these algorithms made it possible to increase the reliability and accuracy of the results of field calculations, since direct control based on analytical formulas in the originals is difficult.

The purpose of computational experiments is to determine the conditions for the existence of interlayer cross flows and their temporal dynamics in the absence of production from the well. Calculations are made for the case when reservoir characteristics of reservoirs are the same. For definiteness, it is assumed that the reservoir, which occurs at a shallower depth, is high-pressure. It is shown that in the absence of production from the well, after some time, an equilibrium pressure that changes slightly with time is established in the wellbore, equal to the average hydrostatic pressure of the lower and upper reservoirs. At the same time, in the region of short times, the flow rate of each reservoir depends on the value of the initial hydrostatic pressure in the well, and in the region of long times, this pressure does not affect the dynamics of interlayer flows. It has been established that the total flow rate of reservoirs is equal to zero only for times longer than the relaxation time. It is noted that the pressure relaxation time in the well increases with a decrease in reservoir permeability.

Amaç: Bu çalışmanın amacı, ışıkla uyarılabilen fosfor (Photostimulable Storage Phosphor, PSP) plakalarının ışınlama-tarama süreçleri arasındaki farklı tarama gecikmeleri (bekletme süresi) ve saklama koşullarının görüntülerindeki Ortalama Gri Değer (OGD) değişimine etkisini değerlendirmekti.
Gereç ve Yöntem: Saklama koşuluna göre oluşturulan dört grupta [Tek Kılıf Aydınlık (TKA), Tek Kılıf Karanlık (TKK), Tek Kılıf Karton Aydınlık (TKKA), Tek Kılıf Karton Karanlık (TKKK)] farklı bekletme sürelerinde toplam 40 görüntü elde edildi. ImageJ (National Institutes of Health, Bethesda, MD) programı ile görüntülerin OGD’leri ölçüldü. Saklama koşullarını karşılaştırmak için tek yönlü, bekletme sürelerini karşılaştırmak için iki yönlü tekrarlı ölçümlü ANOVA testleri kullanıldı. Her bir gruptaki bekletme süreleri ile 0 dk. (altın standart) OGD’lerin karşılaştırılması için eşleştirilmiş örneklemler t-testi uygulandı. p<0.05 istatistiksel olarak anlamlı kabul edildi.
BULGULAR: On dk. ile altın standart arasındaki OGD farkı sadece TKA grubunda istatistiksel olarak anlamlıydı (p<0.05). Herhangi bir bekletme süresinde, saklama koşulları OGD’leri arasında istatistiksel olarak anlamlı fark yoktu (p>0.05). Altın standart dışındaki diğer bekletme süreleri karşılaştırıldığında, 24 saat bekletme süresi ile diğer bekletme süreleri OGD’leri arasında istatistiksel olarak anlamlı fark vardı (p<0.05).
Sonuç: Plakların ışınlama sonrası karanlık ortamda ve karton koruyucu içinde 10 dk.’yı geçmeyen bekletme süresi ile bekletilmesinin OGD’ye etkisi önemsizdi. Sadece plastik bariyerde ve 24 saat sürede bekletilen plakların görüntülerdeki OGD artışı dikkat çekiciydi.

The popularity of online teaching has increased significantly due to the outbreak of Covid-19 which prompted a sudden shift of educational activities to the online environment. In Libya, the government imposed online teaching and television learning programs as “emergency online education”. However, while online education offers numerous benefits as a flexible mode of knowledge delivery, both instructors and students tend to face various obstacles in the teaching and learning process. This study aimed to ascertain the challenges of using e-communication tools and their correlation with teaching experience among EFL instructors in Libyan universities. A total of 100 EFL instructors were examined using a cross-sectional survey method. The data were gathered through a structured questionnaire and analyzed using the mean, frequency, standard deviation, and Pearson correlation. The findings showed that major challenges faced by Libyan EFL instructors in using e-communication tools result from inadequate technical skills and lack of institutional support, followed by lack of student engagement and poor internet connection. The study also revealed a weak correlation between challenges of using e-communication tools and teaching experience among the instructors. This study was envisaged to provide information that can be useful to the Libyan government and higher learning institutions in the process of e-teaching implementation in the EFL context.

Students with special needs usually encounter difficulties in learning English because of their physical, health, or psychosocial challenges. English Teachers’ attitudes to the students’ special needs play a significant role in facilitating the students’ learning process or hindering their learning of English. When a teacher has a negative attitude to the special needs students, this may lead to the teacher not fully covering the planned English syllabus, thus impeding the educational development process of all students. However, an English teacher’s positive attitudes to their profession can certainly influence their students’ attitudes and desire for learning. This study investigates the attitudes of English teachers of special needs students to their profession in schools in Jordan. A quantitative research method was used to collect data from a randomly chosen sample of 155 English teachers. The results of the study revealed that English teachers’ attitudes to their profession were positive and above average, and there was a difference in their attitudes to their profession in general according to the “experience” variable. However, there were no differences in the teachers’ attitudes to their profession according to the “academic qualification.” The findings can contribute to identifying the most important factors that influence the decision-making of newly appointed teachers whether to enter the profession of teaching English to students with special needs.
Regional and Sociolinguistic Variation of Personal Pronouns in Dialects of Najdi Arabic
Authors: Alajmi Nasser M.
Published: September 2023

This study examines the regional and sociolinguistic variation in the paradigms of personal pronouns, independent and dependent, in Najdi dialects. The regional dialects are Central, Qassim, and Northern. The social dialects are sub-varieties of the Central dialect: Hamadan, Hawazin, and Sedentary. The data was collected using the sociolinguistic interview of 25 speakers. It was found that there were more variations in the personal pronoun forms than what have been reported in the literature. When comparing forms with Standard Arabic, the Central dialects are more conservative in the number of changes to the forms. However, Qassim and Northern have retained gender distinction in plural forms while Central dialects did not. This study introduced forms of personal pronouns that were never mentioned in the literature.
Teachers’ Beliefs and Practices Relating to the Use of Tasks in Tertiary English as a Foreign Language Classrooms in China
Authors: Guan Lingling
Published: September 2023

Task-based language teaching (TBLT) has been recommended in the new College English Curriculum Requirement in China (Ministry of Education, 2017) for students learning English as a foreign language. Teachers might not, however, implement these concepts in their classes. This study aims to investigate whether the concept of TBLT has made its way into EFL teachers’ theoretical beliefs and the degree to which TBLT is being put into practice. By using semi-structured interviews and classroom observations, this study investigated the beliefs and practices of three tertiary English teachers in China and their use of tasks in their language classes. The results show that although these teachers had positive attitudes toward TBLT, only some activities in their classes could be classified as tasks. The teachers’ use of tasks seemed to be influenced by web-based textbooks and their own reflective practices. This study provides recommendations for developing language teacher education programmes based on TBLT in China.

This study aims to describe and reveal the main character's emotional management in Defoe's Robinson Crusoe, a Penguin classics novel published in London in 1994. This study employs a descriptive qualitative technique and Sigmund Freud's psychoanalytic approach. The research data was derived from the novel's narrations and portrayal of the main character. The study found that the main character's psychology employed a defensive mechanism to regulate all the emotions that arose. The main character in this work uses suppression, rationalization, reaction construction, regression, anger and indifference, and imagination. Repression serves as the main character's protection mechanism in the narrative. The main character demonstrated that he attempted to channel his melancholy into thankfulness and to turn his anxiety into rational thinking.
Syntactic Characteristic Analysis of Colloquial Makassar Indonesian Based on the Use of Personal Pronoun Affixes: From Interference to Borrowing

This paper will prove the existence of colloquial Makassar Indonesian (CMI) by showing its syntactic characteristics based on the use of personal pronoun affixes. This is very interesting and important because in general colloquial Indonesian languages are spoken in other cities in Indonesia, for example Jakarta, Manado, Ambon, etc. is a subsystem of the Indonesian language (hereinafter abbreviated as IND), but CMI is really a subsystem or subvariant of the Makassar language (MAK), the mother tongue of the Makassarese people. Therefore, it is not easy for Makassar newcomers to master this CMI. To master it, they must first learn the basic rules of MAK syntax. The fundamental thing in this case is the change in language typology, namely CMI has been proven to have adopted the V-S-O (Verb-Subject-Object) typology of MAK. Meanwhile, IND has the S-V-O (Subject-Predicate-Object) typology. This happened because there was language contact between MAK and Malay (now IND), a language which became the forerunner to the birth of IND as the national language and the state language of the Republic of Indonesia. In this case, at first Makassar city residents tried to use Malay, but with MAK syntactic interference. Gradually this form of interference became the entry point for the borrowing of the MAK syntactic subsystem in the IND speeches of Makassar city residents. IND utterances with the characteristics of MAK syntax then become the characteristics of CMI, which has now reached the level of integration and convergence.
