The surimi industry plays a substantial role in bolstering Indonesia’s fishing sector. The collapse of the majority of surimi companies can be attributed to the                   government limitation on trawling, which served as the primary source of demersal fish utilized in surimi processing. This restriction resulted in a significant shortage of raw material for industry. Therefore, it is imperative to explore alternate fish species that can serve as viable raw materials for the production of surimi.  Alternative fish species are needed as raw materials for surimi. The objective of this work was to investigate the physicochemical characteristics and microstructure of surimi produced from two distinct Indonesian fish species: Decapterus sp., a pelagic species, and Priacanthus sp., a demersal species. Five ratios of Decapterus sp and Priacanthus sp; 1:0 (F1: control 1),  3:1 (F2), 1:1 (F3), 1:3 (F4), and 0:1 (F5: control 2) were tested. The proximate composition showed that the addition of Decapterus sp. to the formula increased the protein and fat content of mixed surimi. The formula F4 showed the highest value for almost all textural profile parameters; there were springiness, cohesiveness, gumminess, chewiness, and resilience. The same result also presented in the gel strength, F4 also has the highest value. The Water Holding Capacity value was low, and it showed no difference between all formulas. The whiteness value was in the range of 66-68, and it showed no difference between all formulas. Protein patterns showed no myosin heavy chain in all formulas. Microstructure analysis showed that only F5 (control 2) was compact and denser, but the other formulas (F1, F2, F3, and F4) showed a large number of loose and porous structures. In the microbial analysis, all formulas showed the Total Plate Count value ( 6 x 105 cfu/g) was under the maximum acceptable value (107 cfu/g). The findings of the study indicated that the mixed-surimi, consisting of Decapterus sp and Priacanthus sp at a ratio of 1:3, exhibited the highest level of gel strength. In conclusion, Decapterus sp has the potential to serve as a viable raw material when combined with Priacanthus sp.

El Tomato brown rugose fruit virus (ToBRFV) ha sido descubierto recientemente como una amenaza emergente ya que representa un considerable riesgo económico en la producción de tomate. El objetivo de este trabajo fue aislar al ToBRFV de tres variedades de tomate ubicadas en Coahuila, México. Con el propósito de evaluar la patogenicidad de ToBRFV en plantas de tomate y establecer una escala diagramática que permita una visualización precisa de la severidad de los síntomas en folíolos y frutos. El aislado FQ3 tuvo un impacto significativo en las variables agronómicas de las plantas de tomate, a través de una disminución del 53.9 % en la altura de la planta y del 38.9 % en el peso seco de la parte aérea de la planta. En cuanto a las variables de calidad, se observó una reducción del 43.1 % en el diámetro ecuatorial del fruto y del 43.2 % en el rendimiento de los frutos. La aplicación de una escala diagramática permitió una cuantificación más precisa de la severidad causada por los diversos aislados de ToBRFV. Se identificó que el aislado FQ3 generó una incidencia que osciló entre el 33.9 al 50 % y una severidad entre el 41 al 87.5 % más en comparación con los otros aislados. Estos descubrimientos demuestran la importancia de comprender y gestionar la variabilidad en la respuesta de las plantas de tomate a diferentes aislados de ToBRFV, lo cual puede tener consecuencias importantes para la producción de tomates afectados por esta enfermedad.

Authors: Gandhi Sumit , Murthy Yogesh Iyer , Singh Ram Pal
Published: June 2024

Analysis of flow in an abruptly expanding channel for five characteristics namely sequent depth ratio Y2/Y1, efficiency E2/E1, relative height of jump hj/E1, relative length of jump Lj/Y1 and relative length of roller Lr/Y1 were studied experimentally and using response surface method (RSM) technique. Physical explanations of these characteristics against Froude number were also discussed based on experiments. Dimensional analysis has also been followed for different fluid properties and geometric dimensions of the set up for reducing number of complexity involved in hydraulic jump phenomenon. Obtained results are well presented as regression models for all flow characteristics. Furthermore, RSM is applied to determine most significant parameter influencing jump characteristics and to identify any unusual behaviour of flow parameters. The central composite rotatable design was employed to generate the experimental runs using Minitab software version 21. These developed models are characterised as highly accurate as prediction efficiency of RSM model is deemed highly effective for sequent depth, relative height, efficiency, relative length of roller and relative length of jump as reflected in the Nash–Sutcliffe efficiency values within the 0.9 NSE range.
Factor Selection and Structural Breaks
Authors: Chib Siddhartha , Smith Simon C.
Published: June 2024

We develop a new approach to select risk factors in an asset pricing model that allows the set to change at multiple unknown break dates. Using the six factors displayed in Table 1 since 1963, we document a marked shift towards parsimonious models in the last two decades. Prior to 2005, five or six factors are selected, but just two are selected thereafter. This finding offers a simple implication for the factor zoo literature: ignoring breaks detects additional factors that are no longer relevant. Moreover, all omitted factors are priced by the selected factors in every regime. Finally, the selected factors outperform popular factor models as an investment strategy.
Evaluation of different surface characteristics and mineral grain size in the estimation of rock strength using the Schmidt hammer
Authors: Karaman K.
Published: June 2024

This study investigated the effect of surface roughness on Schmidt rebound hardness (Rl). Four different test surfaces of rock samples were studied: natural, ground, cut surfaces, and core samples. There was significant variability of standard deviation based on the Rl on the natural surface, which indicated high roughness of the rock surface, whereas surface polishing caused a significant decrease in standard deviation. ISRM and ASTM methods were compared to estimate unconfined compressive strength (UCS) for different testing surfaces. Rl obtained from the cut surface was found to be more reliable than those obtained from other testing surfaces for the prediction of UCS; however, regression and ANOVA analyses revealed that the ISRM method gave a more accurate UCS estimation of rocks with highly rough surfaces. It was also shown that Rl values obtained from a cut surface were significantly higher than those obtained from core samples. Therefore, a comparison between Rl values obtained from core samples and cut surfaces was made based on previous studies. This study statistically showed that estimated UCS values are not statistically significant if Schmidt rebound tests are not performed on similar surfaces. In addition, the mineral grain sizes of the studied rocks, different testing surfaces compared with those in literature, and standard deviation from Rl are evaluated and discussed. The Schmidt hammer technique is a rapid, inexpensive, and straightforward method for estimating UCS for preliminary assessment; however, roughness of the surface should be eliminated if variations are shown in the surface rebound hardness.

Authors:   Assistant Professor, Department of Statistics, Madras Christian College, Chennai, 600059, Tamil Nadu, India, Haridoss V , Sasikala V
Published: June 2024

Objectives: Optimizing the sum of risks involved in the selection of acceptance sampling plans playing a vital role. This paper uses the Hurdle Poisson distribution to design an optimal quick switching system attribute plan for a given acceptable quality level (AQL) and limiting quality level (LQL) involving a minimum sum of risks. Methods: The sum of producer's and consumer's risks has been met for the specified AQL and LQL. The sum of these risks, as well as the acceptance and rejection numbers have been calculated using the Hurdle Poisson distribution. The operating characteristic function for the quick switching system attribute plan has also been derived using the Hurdle Poisson distribution. Findings: The producer and the consumer both represent the same party in the final inspection. As a result, the sum of these two risks should be minimized. In this paper, the sum of risks for various operating ratios are tabulated using the Hurdle Poisson distribution. These tabulated values are less than the sum of risks calculated using the Weighted Poisson distribution. Novelty: Reducing the sum of risks is the ultimate aim of the work. In this proposed paper, to attain the minimum sum of risks, the authors make an attempt to approach the Quick Switching System Sampling Plan, when the number of defectives in the submitted lots are very less. In other words, the probability of getting defective is very less. This indicates the quality of the lot selected for the inspection to ensure the protection for the consumer. And the plan is also designed in the way that the producer is also not get affected by rejecting a good lot by the consumer. This is the requirement of minimizing the risks.

Modeling Extreme Values of Non-Stationary Precipitation Data with Effects of Covariates
Authors:   Professor, Department of Statistics, Bharathiar University, Coimbatore-46, Tamil Nadu, India, Sakthivel K M , Nandhini V
Published: June 2024

Background/Objectives: Climate change is one of the most challenging problems of recent decades as it is highly volatile and needs a very effective scientific approach to find a solution. Further, the changes in the climate especially extreme cases have a more negative influence on day to day affairs of society. Hence, developed countries pay much attention to climate change and make policies at a global level. To find the scientific solution for these kinds of climate change, Extreme value theory offers effective methods for estimating and quantifying these types of natural hazards associated with climate. Methods: Block (Annual) maxima and peak over threshold are two strategies employed in this theory. The data observed on precipitation are mostly having non-stationary characteristics along with covariates. The generalized extreme value distribution and generalized Pareto distribution are used to model this type of non-stationary stochastic process. Findings: This study proposes a pragmatic automated dual-phase threshold selection technique that employs the entropy method to combine the results from various goodness of fit tests into a single unified measure known as the evaluation indicator, resulting in an efficient threshold for capturing extreme values. This allows for a more comprehensive examination of various thresholds using evaluation indicators and avoids assessing each test criterion individually. Novelty: In contrast to the subjective results of threshold stability plots, the dual-phase technique is based on numerical computations, which reduce bias and improve decision-making objectivity. We illustrate the applicability of the proposed technique by analyzing a precipitation dataset that includes time and wind speed as covariates. The results of the comparative analysis reveal that the proposed automated dual-phase threshold approach outperforms the peaks over threshold and annual maxima methods. Keywords: Non-stationary, Extreme values, Annual maxima, Threshold selection, Evaluation indicator
Magmatic and Geochemical Studies of Early Neoproterozoic Koraput Anorthosite Massif, Eastern Ghats Mobile Belt and their Implications for Rodinia Assembly
Authors: Saikia Dicton , Nasipuri Pritam
Published: June 2024

This paper reports new mineralogical and geochemical information on the Neoproterozoic Koraput Anorthosite pluton in domain-2 of the Eastern Ghats Mobile Belt. The lenticular-shaped, NE-SW trending small Koraput Anorthosite Pluton is dominated by gabbro-anorthosite, anorthosite sensu-stricto, and norite-diorite. Isolated patches of ferrodiorite (residual melt following crystallization of anorthosite) occur at the pluton margin. The estimated magmatic P-T conditions for anorthosite emplacement are ~1000°C and ~1.1GPa. In addition, the intermediate Anorthite (48-52 mole %) presence in plagioclase of gabbro-anorthosite and anorthosite indicates plagioclase crystallisation and accumulation at 30-40 km (circa 1 GPa) depth near the crust-mantle boundary. Furthermore, the geochemical traces suggest Koraput anorthosite pluton crystallized from a less fractionated basaltic magma. The REE and trace element systematics of anorthosite and norite-diorite exhibit enriched LILEs over depleted HFSE with negative Nb, Ta, Th, and Zr anomalies. Gabbro-anorthosite and ferrodiorite, on the other hand, exhibit positive Nb, Ti, and negative Zr and Th anomalies. Nb/Th versus Nb/La diagram implies lithodemic units in Koraput Anorthosite pluton are variably contaminated by crustal sources. Integration of geochemical data with available monazite age suggests that the Koraput anorthosite pluton in isotopic domain-2 of the Eastern Ghats Mobile Belt was emplaced during the collision between proto-India and Antarctica during the Rodinia assembly.

Authors: Sion Kumari P. , Gupta Sandeep , Mandal Prantik
Published: June 2024

Hyderabad and its surrounding region are situated within Eastern Dharwar Craton, primarily composed of Archean granite. We use ambient noise tomography to obtain the 3-D shallow subsurface shear seismic velocity structure of 150 x 200 km2 area around Hyderabad. We used continuous waveforms that were recorded by a digital seismic network with 10 three-component broadband seismographs from November 2020 to December 2021. Using the vertical component of waveforms, the Empirical Green’s functions (EGFs) have been estimated, and the group velocity dispersion curves in the time period range of 1.0–10 s have been extracted from these. We inverted these dispersion curves to estimate 3-D variation of shear wave velocity by using direct surface wave tomographic method. The results suggest that the subsurface velocity structure is heterogeneous. The shear wave velocity varies from 3.4 to 3.7 km/s in the shallow subsurface. The limited seismicity in this area is mostly confined to the boundary between high and low-velocity changes.

Published: June 2024

Eastern Karakoram is one of the least studied areas with respect to glacial geomorphology due to its remoteness and inaccessibility and hostile climatic conditions, hence the use of remotely sensed data is indispensable in studying glaciers and related features of the region. In the present article, we present a comprehensive description of the glacial landforms and landscape evolution in the Rongdo basin Eastern Karakoram Ladakh, India. The region is dominated by well-preserved glacial features which offer an excellent opportunity to map and evaluate past glacial fluctuations. The mapping was carried out using high-resolution satellite data (Planet images), and Google Earth, along with ASTER GDEM scenes supplemented by field-based observations to delineate and map various glacial-geomorphological features in the region. The geomorphological landforms mapped include various types of erosional and depositional features. Based on the position of frontal and lateral moraines and glacial trimlines it is evident that the region has witnessed multiple episodes of glacial advances and experienced huge glacial thickness in the recent past. The study highlights role of a number of variables, including topography, climate, and geology, that have contributed to the formation and evolution of landscapes in study area. However detailed dating of the landforms in the region is vital in understanding the past glacial fluctuations and the impact of the climatic variations on the glaciers of the region.

Authors: Langerova Tatiana , Spence Holly , M Waldron Fergal , Gregory Jenna
Published: June 2024

Background: TDP-43 aggregation is the hallmark pathology seen at post-mortem in the majority of Amyotrophic lateral sclerosis (ALS) cases. Lipid metabolism has been shown to be disrupted in ALS including evidence for systemic metabolic disruptions in ALS patients as well as lipid peroxidation changes noted at the single cell level. The temporal nature of lipid dysregulation during disease course and the role that lipid dysregulation may play in potentiating TDP-43 pathology is unclear. Aim: The aim of this review is to analyse existing literature assessing the interplay between altered lipid metabolism and TDP-43 pathology in ALS, and investigate possible relationships between the two. Methods: This protocol describes the strategy for a proposed systematic review and meta-analysis to identify, evaluate and analyse studies examining lipid changes in relation to TDP-43 pathology. Summary: This review will aid our understanding of ALS-associated pathobiology through detailed analysis of molecular processes underlying the influence of lipids on TDP-43 behaviour in ALS.

MIGRAÇÃO INFANTIL NAS TRAVESSIAS CONTEMPORÂNEAS BRASILEIRAS: AS FACES DA VULNERABILIDADE SOCIAL NAS RACHADURAS DA INFÂNCIA PERDIDA
Authors: De Oliveira Souza Tourinho Luciano , Da Silva Sotero Ana Paula
Published: June 2024

As migrações contemporâneas exsurgiram as fragilidades discriminatórias dos países diante da dificuldade da concretização dos direitos humanos aos povos migrantes e refugiados. Tal conjuntura revela que os migrantes e refugiados sofrem o processo de dupla vulnerabilidade social. A primeira verificada no seu país de origem, quando a ingerência dos direitos humanos obriga os sujeitos a se deslocarem de forma forçada. Já a segunda vulnerabilidade é reflexo da exclusão e práticas de xenofobia contra os povos migrantes e refugiados nos países receptores. Na esteira dessa linha de intelecção, a intensificação das migrações no Brasil tem provocado o aumento da vulnerabilidade dos povos migrantes e refugiados, diante da exclusão e marginalização das populações em deslocamento. Em um recorte do perfil do migrante, destacamos que o público infantil tem sofrido com mais intensidade os efeitos das práticas discriminatórias, quando são desassistidas dos seus direitos sociais e invisibilizadas enquanto sujeitos autônomas de direitos do seu núcleo familiar. Por esse viés, o presente estudo tem por objetivo analisar o perfil migrante e refugiado infantil no Brasil a fim de investigar as vulnerabilidades enfrentadas que dificultam o pleno exercício dos direitos humanos. Para tanto, a metodologia aplicada no estudo se concentrou em uma abordagem exploratória, com a análise bibliográfica de cultores da área de migrações e documental, com a análise dos dados brasileiros do perfil infantil nas migrações contemporâneas.

Published: June 2024

The teaching methods employed by teachers are interconnected with their educational philosophy tendencies. Determining teacher candidates' teaching style preferences and philosophical orientations toward education, as well as studying their relationship, might provide insights about the classroom environment they will establish when they begin their teaching career in the future. To examine this connection, this study aimed to compare the educational philosophy tendencies of PE teacher candidates, their preferred teaching styles, and their value perceptions of styles based on gender and grade levels and to determine if there is a relationship between philosophical tendencies and teaching style preferences. The research included 242 PE teacher candidates. The study utilized the "Physical Education Teachers' Use of Teaching Styles and Perceptions of Styles Questionnaire" and "Educational Philosophy Tendencies Scale" for data collection. The data was analyzed using independent samples t-test, ANOVA, and Pearson correlation analysis. The research results revealed that among the educational philosophy tendencies of PE teacher candidates, there was only a difference in the essentialist philosophy of education according to gender, and there was no difference according to grade level. However, it was observed that the teaching style preferences of PE teacher candidates did not differ according to gender and grade level. The study revealed a correlation between the preferred teaching styles, the value perceptions of these styles, and the educational philosophy approaches of teacher candidates.

Changes in the level of tyrosinase expression in the retinal pigment epithelium during the development of experimental optic nerve degeneration
Authors: Barieva Aigul M. , Valiullin Viktor V. , Samoilov Alexander N.
Published: June 2024

BACKGROUND: With optic nerve degeneration of various origins, retinal neurons are the most vulnerable, and their state under these conditions has been studied in sufficient detail. At the same time, the retinal pigment epithelium plays a very important role, realizing the synthesis of melanin and performing antioxidant, phagocytic, transport, protective, and homeostatic functions. Tyrosinase serves as a key enzyme in melanogenesis by cells of this epithelium. The development of methods for early diagnosis of optic nerve atrophy is extremely important due to the fact that functional visual impairments appear later than structural ones, at more advanced stages of the disease. The retinal pigment epithelium cannot be insensitive to the processes that occur during optic nerve degeneration. That is why its study in experimental degeneration of the optic nerve is necessary for a more complete understanding of the processes occurring in the visual analyzer under these conditions.
AIM: To study changes in the level of tyrosinase expression in the retinal pigment epithelium at different development stages of experimental optic nerve degeneration based on morphological data.
MATERIAL AND METHODS: The subjects of the study were 40 rat eyes after creating a model of optic nerve atrophy using methanol. The animals were divided into five groups: the first group — control; the second to fifth groups included animals whose eyes were enucleated 1, 3, 6 and 9 weeks after the creation of the aminophylline-methanol model of optic nerve atrophy, respectively. The retinal pigment epithelium was studied using fluorescent antibodies to tyrosinase Tyrosinase Mouse Monoclonal. Immunofluorescence staining was performed on fixed transverse sections of the eyeball. Statistical analysis and visualization of the obtained data were carried out using the environment for statistical computing R 4.2.2.
RESULTS: A comparative analysis of the results obtained revealed that the level of tyrosinase expression in the fifth group was on average 4.21 times [95% confidence interval (CI) 2.49–7.13, p=0.00076], 9.31 times (95% CI 5.47–15.85, p=0.00033), 2.63 times (95% CI 1.51–4.58, p=0.0009) and 3.44 times (95% CI 1.96–6.03, p=0.00055) higher compared to the first, second, third and fourth groups, respectively. The level of tyrosinase in experimental samples in the first, third and fourth groups was statistically higher compared to the level of tyrosinase in the second group by an average of 2.21 times (95% CI 1.33–3.66, p=0.0003), 3.53 times (95% CI 2.08–6.02, p=0.00069) and 2.71 times (95% CI 1.58–4.65, p=0.00022), respectively.
CONCLUSION: As degenerative processes develop in the optic nerve fibers under these conditions, the integrity of the retinal pigment epithelium is disrupted, which is characterized by an increase in antibodies to tyrosinase in the retinal pigment epithelium of experimental animals.

Published: June 2024

Backgrounds/Aims: Atezolizumab/bevacizumab is the recommended first-line systemic therapy for unresectable hepatocellular carcinoma (uHCC) and may facilitate curative conversion through resection and locoregional therapies. However, there have been very few reports on curative conversion using microwave ablation (MWA). This study aimed to determine the curative conversion rate with MWA using atezolizumab-bevacizumab as the first-line treatment in patients with uHCC, and to compare the characteristics and survival of patients with and without curative conversion.Methods: Consecutive patients with uHCC who were started on atezolizumab-bevacizumab from May 2021 to December 2023 in a single tertiary center were included. Objective response rate (ORR) and disease control rate (DCR) were based on the Response Evaluation Criteria In Solid Tumors (RECIST) 1.1 and modified RECIST (mRECIST) criteria.Results: Twenty consecutive patients with uHCC (60% advanced-stage) were included, 90% exceeding the up-to-7 criteria. The ORR and DCR were 35% and 60%, 35% and 55% using RECIST and mRECIST, respectively. Five patients (25%) underwent successful curative conversion with MWA (four advanced and one intermediate stage) despite a median HCC size of 6.1 cm (range, 2.4-7.3). Two of these patients were tumor and drug-free 132-133 weeks from the 1st atezolizumab-bevacizumab dose. Patients who underwent curative conversion had significantly longer survival than those who did not (P=0.024). Other factors associated with survival were male sex, Child-Pugh class A, and an objective response.Conclusions: Despite the relatively large tumor size, successful curative conversion with MWA was achieved with first-line atezolizumab-bevacizumab in uHCC. However, data from prospective multicenter trials are required to determine whether this strategy is universally applicable.

O “Programa de Residência Pedagógica” (PRP) de 2018 é voltado a inserir estudantes de licenciaturas em escolas conveniadas para uma imersão em seu futuro local de trabalho. Este texto apresenta dados de uma investigação em colaboração com o grupo de pesquisa do IF lócus. O objetivo foi identificar as contribuições do PRP que tangenciam as aprendizagens da profissão docente pelos residentes, evidenciando entraves e benefícios do programa para a formação inicial. Os instrumentos para coleta de dados foram as narrativas apresentadas nos portfólios produzidos pelos residentes e a aplicação de questionários nos 122 residentes do programa. Neste estudo, constatou-se que os residentes reconheceram o aperfeiçoamento de sua formação inicial como futuros docentes e que as atividades oportunizam as aprendizagens da docência. Considerou-se que iniciativas de melhoria na formação docente são relevantes, porém devem vir em conjunto com melhores condições de trabalho, valorização e investimentos na Educação Básica.

Authors: Costa Angelina Carlos , De Sousa Daniela Rodrigues , Nunes Cruz Ivanildes da Glória , Rogeri Raquia Rabelo
Published: June 2024

Resumo: O presente artigo tem como objetivo apresentar um estudo a partir dos escritos de Paulo Freire, com foco na categoria pensar certo, e as contribuições destas perspectivas na superação da dicotomia teoria e prática, colaborando com a formação do professor e de sua identidade profissional, na disciplina de Estágio Supervisionado dos Cursos de Pedagogia. A metodologia utilizada foi a pesquisa bibliográfica. A partir dos estudos realizados é possível compreender que o exercício do pensar certo possibilita não apenas a construção de conhecimentos por parte dos estudantes, mas a possibilidade de todos os envolvidos no processo (professor supervisor do Estágio Supervisionado, escola campo, estudantes, comunidade, entre outros) produzirem dialogicamente cultura, aprendendo coletivamente a aprender. E os estudantes, ao se tornarem professores, poderão se reconhecer no mundo e com o mundo, pois aprenderam a ensinar, o que lhes propiciará identificar a unidade entre teoria e prática, com vistas à transformação do mundo.
A AÇÃO DIALÓGICA DE PAULO FREIRE E OS PROCESSOS FORMATIVOS EM CONTEXTOS DE RESISTÊNCIA
Authors: Duarte Aldimar Jacinto
Published: June 2024

No presente artigo busca-se analisar a importância de os intelectuais (lideranças/educadores) em se fundamentarem na perspectiva teórica e metodológica de Paulo Freire, em especial no que concerne à ação dialógica, enquanto processo de enfretamento ao desmonte da democracia no Brasil nos últimos anos. A pesquisa, fundamentada em Paulo Freire e outros autores que analisaram e analisam criticamente a realidade brasileira e os processos de construção/desconstrução da democracia no mundo ocidental, conclui que o processo efetivo de resistência está no diálogo solidário e humilde junto ao povo, por meio do envolvimento radical e dialógico com os excluídos na luta pela defesa dos direitos humanos, da democracia, da cidadania ativa e da justiça social como valores inalienáveis, em todos os espaços sociais.

Investigating the Existence of Egyptian Colloquial Arabic (ECA) in the Language Learning Context
Authors: Arifianto Muhammad Lukman , Izzudin Iqbal Fathi , Mujahidah Zulfa Azalia
Published: June 2024

Many scholars have discussed Egyptian Colloquial Arabic (ECA), especially concerning its structure and comparison with Standard Arabic, Modern or Classical.  However, whether it is a phenomenon of language variation (diglossia) or it could be a language deviation from the Arabic grammatical rules has not been specifically explored. For this reason, this paper examines the ECA concerning its emergence and existence in Arabic language learning. Literature studies on several reference books and articles about ECA were carried out to present the views of experts regarding this discussion.  Based on the results, it can be noted that there are two significant opinions regarding the existence of ECA in the language learning context. The scholars who posit that the ECA is a language deviation inherited the paradigm from the prescriptive study of language adopted by traditional linguistics schools. This perspective appeared as a consequence of the emergence and development of Arabic grammar, as well as the standardization of the language applied at that time. Meanwhile, the scholars who consider the ECA as a phenomenon of language variation tried to objectively portray and describe this language as they learned from the results of research on Egyptian sociolinguistics. This paradigm is in line with structural or modern linguistics which is more focused on the object of study. The results of this study can be used by Arabic language institutions & lecturers as consideration whether to include colloquial language elements in their Arabic teaching or not.
German minority in urban space of a textile manufacturing centre: the case of 19th century city of Łódź
Authors: Marszał Tadeusz
Published: June 2024

German settlement in Poland has been the subject of numerous studies. The causes and determinants of migratory movements have been discussed extensively, while little attention has been paid to the spatial aspects of the phenomenon. The aim of this study, which is part of geographical and historical research, is to determine the size of the influx of migrants of German nationality into the rapidly developing textile production centre of Łódź in the 19th century, as well as the geographical origins and distribution of this nationality group in the urban space. These considerations are complemented by the identification of key issues related to the social integration and assimilation processes of the German minority. In the first half of the 19th century, the influx of skilled labour, almost entirely recruited from the German population, conditioned the development of the textile industry in Łódź. It also had a key influence on the demographic development of Łódź, which soon became the largest centre of textile production in Poland. In subsequent decades, there was a tendency among German immigrants towards separation in the sphere of professional and social activities, but already by the end of the 19th century the German community settled in Łódź was diverse in terms of the sense of nationality. In addition to a certain proportion of the immigrants who were already Polonised, there were persons declaring German nationality, as well as those undecided about the issue.
