Authors: Al-Byati Mansour Kareem Abd Ali , Al-Duhaidahawi Aqeel Mahdi Jreo
Published: January 2023

In this research, the aluminum oxide nanoparticles (Al2O3 NPs) were prepared using electrochemical method. The Features of the electrochemical process are ease and speed, free side product, and economical. The prepared aluminum oxide was characterized using many techniques like x-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), ultra violate – visible (UV-Vis), energy dispersive x-ray (EDX), and atomic force microscopy (AFM). The shape of the prepared aluminum oxide was in the form of nanowire and has an energy gap of 3.9. Since fossil fuels are rapidly running out and their consumption increases the average global temperature, which has an impact on human life, the energy crisis is the main global concern. Consequently, in order to generate energy, dye sensitized solar cells (DSSCs) must be produced. The results indicate that the efficiency (η %) of the solar cell using methyl orange as a dye and fill factor were 1.17 and 56.8, respectively.

Published: January 2023

Skin cancer, one of the most common cancers worldwide, accounts for around one- third of all diagnosis. The main cause of skin cancer is unrepaired DNA breaks in skin cells, which result in genetic mistakes or skin mutations. The importance of early detection of skin cancer symptoms cannot be overstated given the rising incidence, high mortality rate, and expensive medical treatments. Researchers have created several early skin cancer screening methods due to how hazardous these problems are. Skin cancer is identified and benign skin cancer and melanoma are distinguished using the lesion's features, such as its symmetry, colour, size, and form. Dermatologists make a diagnosis based on the layer-by-layer arrangement of skin lesions. CNN was superior to even board-certified dermatologists. Additionally, methods that enlist mechanical aid to detect cancer are more successful. Artificial intelligence that organises information and generates decision-making processes in a manner like that of the human brain.
A Review Paper on Brief Study on Breast Cancer Classification using Deep Learning

Published: January 2023

The biggest cause of cancer-related deaths among women is breast cancer. The greatest and most efficient method to slow the growth of a tumour is early detection and diagnosis. The currently advised imaging technique for the early detection and diagnosis of breast cancer is mammography. Mammogram mass classifications continue to be a major difficulty and are essential for helping radiologists make an accurate diagnosis. The precise detection and classification of breast cancer is a crucial task in medical imaging because of the complexity of breast tissues. Due to their ability to automatically extract characteristics, deep learning techniques have been successfully applied in a wide range of industries, but particularly in the field of medical imaging. In order to identify and classify breast cancer on histopathology images, this research suggests an unique patch-based deep learning technique called Pa-DBN-BC (DBN). To extract features, unsupervised pre-training and supervised fine-tuning phases are performed. The network automatically extracts features from picture patches. To categorise the patches from histopathology images, logistic regression is performed. The model receives the characteristics extracted from the patches as input, and it outputs a probability matrix with either a positive sample (cancer) or a negative sample (background).

Published: January 2023

Micro, small, and medium-sized businesses (MSME) are currently the main targets of cyberattacks in India, yet the fact is that their environment frequently overlooks the prevention of cybercrime. We attempted to introduce a somewhat more robust, self reliant, and efficient cybersecurity solution that can enable higher oppportunity to each individual enterprise's evolving needs and can also quickly adjust with the constantly changing threat environment over the cyber space. Cybersecurity is an environment that is highly demanding and challenging due to the various data transmission layers and the supported IoT devices. The various technologies and tools that can be used to build a cyber security framework specifically for MSMEs are reviewed in this article.

Published: January 2023

Human action recognition is the process of labelling image sequences with action labels. Robust solutions to this problem have applications in domains such as visual surveillance, video retrieval and human–computer interaction. The task is challenging due to variations in motion performance, recording settings and inter-personal differences. In this survey, we explicitly address these challenges. We provide a detailed overview of current advances in the field. Image representations and the subsequent classification process are discussed separately to focus on the novelties of recent research. Moreover, we discuss limitations of the state of the art and outline promising directions of research.

Published: January 2023

Background: In this study, it was aimed to test the anti-tumoral effects of melatonin in vivo. In the literature review, no study was found that examined the anti-tumoral effect of melatonin at night on an experimental tumor model in vivo. Therefore, in the study, the anti-tumoral effect of melatonin was tested in solid tumor tissue formed in Swiss albino male mice.
 Methods: Swiss albino male mice formed Swiss albino male mice in vivo and 80 Swiss albino male mice weighing 25-30 g and aged 10-12 weeks were used. The subjects were divided into 10 groups in total (n=8). These groups are divided into two main groups as light and dark. All animals except the control group were injected intramuscularly (i.m.) with EAT to create EST in the right leg scapula of the subjects. Different doses of melatonin were injected intraperitoneally (i.p.) daily to the experimental groups. EST was created by inoculating EAT 2 days after administration of melatonin. Melatonin application was made between 18:00 and 20:00 in the evening. In addition, light groups were exposed to 580 µW fluorescent light between 02:00 and 04:00 at night. Daily food and water consumption and weight gains of all animals were followed and recorded, and the application was continued for 14 days. Cardiac blood was collected from all animals with heparinized syringes on the 15th day of the experiment and tumor tissues were removed ambuloc. At the end of the experiment, all animals were sacrificed under ether anesthesia.
Results: The MDA and GSH parameters in the cardiac blood taken from the subjects were examined and the diameters of the tumor tissues were measured and examined under a light microscope. Weight change in all groups was not statistically significant (p>0.05). It was found that the increases and decreases in the MDA and GSH values of the light and dark groups were not statistically significant (p>0.05). It was determined that there was no statistically significant difference between the tumor diameters of the control light groups and the tumor diameters of the other light groups (p> 0.05). While the difference between the control of dark groups and the tumor diameters of Group K2 was not statistically significant (p>0.05), the increase in tumor diameter of the subjects of Group K3 and Group K4 was found to be statistically significant (p<0.05).
Conclusion: As a result; in this study, which investigated the effects of melatonin on experimental EST in dark and light environments, it was revealed that it did not show any positive effect on MDA and GSH levels.

SCHOOL EDUCATION AND THE PLURILOCALITY OF TEACHING EVOKED BY CONTEMPORANEITY
Authors: Moraes Armesto Leonardo , Paiva Gonçalves Bispo Patrícia , Roberto Alonso Thabata
Published: January 2023

Contemporaneity assumes, every day, the aggregation of a series of tools and mechanisms based on the possibilities of contributing to the training process of more active and knowledgeable citizens in their participation in the local context. This re-dimensioning consolidates itself in an increasingly faster social environment and full of deconstructions based on globalization that expands and links discussions, as well as the dynamics of plurality that problematize the forms, roots and aspects of the environment and of being. Nevertheless, it is part of this rhythm to bring to the school environment, whatever it may be, movements that are as typical as they are commonplace that transform the world every day and that forge new demands and requirements of the living being and inherent to its reality and to the narrowing influence that a locality exerts on the others that surround it. This makes the school a prosperous environment for the formation of ideas and generation of knowledge of the present time in contact with past history and the derived future.

Published: January 2023

This article presents an observation that was accomplished with the support of the Pefop (Paradigmas Educacionais e Formação de Professores) research group, at a private Elementary school with the objective to analize the school management culture over the professional development of teachers focusing on the paradigm of complexity. It was defined as the research problem: how do school culture and its management leaders motivate and have impact on professional development of teachers and their pedagogical practices in Elementary school. In a qualitative approach, as a study case, in which twenty teachers were involved, the school principal and two coordinators. In the process, it was chosen to have semi-structured interviews, classes observations and follow-up report about the courses teachers are due to accomplish during the school year. We concluded that, teacher in elementary school have no knowledge about the paradigm of complexity although they present some pedagogical techniques that are related to such approach, even though they are subject to the traditional method of teaching but with the support and motivation from school leaders, they are able to keep improving each day and making the difference in their students´ lives.
BODY, GENDER AND SUBVERSION
Authors: Jonas Ribeiro Magno
Published: January 2023

The present paper intends to show how the relationship between gender, body and its transdisciplinary problems occurs. Such conception is explored in the work to understand in which given gender inequality gained a linguistic legitimation in its existence, thus contributing to the submission and exclusion of women as an egalitarian presence to exist. For this, it was used as method of investigation the philosophy of the language to make such route in the history of the old philosophy. Also made use of Ludwig Wittgenstein’s philosophy of language, more precisely the concept of “language games” to better understand the relation and subversion of gender in the present day. And lastly, this course intends to think about the importance of women’s autonomy in their authentication of a body, the result of the origin of metaphors and the production of subjectivity.
El complemento por aportación demográfica: dislate legal de incesante conflictividad judicial aun después de derogado («no muerto»)
Authors: Molina Navarrete Cristóbal
Published: January 2023

La introducción en el sistema de pensiones públicas españolas del complemento de maternidad por contribución demográfica a la Seguridad Social (art. 60 Ley general de la Seguridad Social, en la versión de 2015) fue un gravísimo error de técnica legislativa, con altos costes sociales y económicos. Una vez fue declarado discriminatorio contra los hombres por el Tribunal de Justicia de la Unión Europea (diciembre de 2019), el retraso excesivo en realizar el debido cambio legal (RDL 3/2021, de 2 de febrero) agravó las disfunciones. La aplicación posterior por los tribunales sociales, en vez de contribuir a dotar de una mayor coherencia la institución, la ha convertido en cada vez más irracional. Por lo tanto, la derogación de esta regulación legal no ha impedido una enorme conflictividad judicial, con decenas de miles de asuntos pendientes de resolver, muchos de ellos en el Tribunal Supremo. La gestión administrativa de esta figura tampoco ha contribuido a su racionalización, al contrario, la resistencia de la entidad gestora a cumplir con los dictados jurisdiccionales, aunque discutibles, ha creado problemas adicionales, también la condena al pago de indemnizaciones por daños morales. Este comentario analizará las decisiones judiciales más recientes en la materia, en el contexto de una nueva reforma del complemento por reducción de la brecha de género.
Integración de lagunas en clave de género: ¿más allá de las pensiones del RETA?
Authors: González Cobaleda Estefanía
Published: January 2023

Se evidencia una vez más, a golpe de sentencia, la exigencia de una corrección profunda del derecho de la Seguridad Social en clave de género. Esta perspectiva se ha puesto de nuevo de manifiesto en la Sentencia del Juzgado de lo Social número 1 de Granada 434/2022, de 13 de octubre. En efecto, más que a una interpretación flexible de las normas reguladoras, esta sentencia lleva a una lectura correctora, reescribiendo su sentido en aras de la igualdad de resultados entre mujeres y hombres, concretamente, acerca de la técnica de integración de lagunas de cotización. Precisamente, en ella se equiparan las situaciones asimiladas al alta por inscripción como demandante de empleo a las de ausencia de tal inscripción en periodos dedicados al trabajo reproductivo, no tanto por su condición biológica de mujer, sino por el género, esto es, por la construcción sociocultural sexista creada en torno a aquella, en especial a la hora del reparto del trabajo de cuidar.
Proyecto de inclusión tecnológica para el estudio de la percusión corporal
Authors: Bravo Fuentes Paloma
Published: January 2023

El cuerpo y la voz son los primeros instrumentos que se emplean en la educación musical siguiendo las premisas de las principales pedagogías musicales. En lo referente a las posibilidades sonoras del cuerpo en la práctica instrumental, la percusión corporal es una de las actividades que se realiza en las aulas de educación musical en la etapa de Primaria. Sin embargo, como toda practica instrumental, requiere un seguimiento por parte del docente especialista en la materia para que los estudiantes (niños y niñas) adquieran los conocimientos de forma sistematizada y en orden creciente de dificultad. Debido a que la duración de las sesiones de Música en esta etapa educativa es de apenas una hora y que incluyen a un grupo numeroso de estudiantes, se hace muy complejo realizar una enseñanza y seguimiento individualizado del alumnado. Por esta razón, resulta necesario que el alumnado continúe con la práctica instrumental de forma autónoma fuera del centro educativo. Para evitar la ausencia de esa guía fundamental se crea este proyecto de inclusión de una app en este proceso de enseñanza-aprendizaje de la percusión corporal.

Authors: Simeon Ekpete, Marshall , Juliet Ifechi* Kenn-Ndubuisi,
Published: January 2023

The purpose of this study is to investigate the relationship between macroeconomic effects on stock market returns in Nigeria employing the CBN annual time series data spanning from 1985-2019. The study applied unit root test, auto-regressive distributed Lag and granger causality tests to investigate the relationship between all share index and interest rate, inflation rate, exchange rate. The unit root tests results for stationarity revealed that the entire variables are reliable for economic decisions. The findings of the study revealed that interest rate was negative and not significantly related with the all share index; also inflation rate was negative and not significantly related with the all share index while exchange rate was positive and significantly related with the all share index. The granger causality result revealed Uni-directional causality which implies no causality. This study recommends that macroeconomic factors should be adequately managed by the Central Bank of Nigeria with the view to promoting investors confidence in the stock market.
Effect of Finance Act on the Minimization of Tax Conflict and Incidence of Double Taxation in Nigeria
Authors: Monday* Osirim,
Published: January 2023

This paper examined key contentious tax issues in Nigeria and the policy implication of resolving these issues using a fiscal instrument of the Finance Act. To achieve this objective, controversial tax issues in Nigeria ranging from tax legislation to administration and tax policy matters were examined from conceptual, theoretical and empirical perspectives utilizing dual research objectives, questions, hypotheses and theoretical underpinnings. The sample size of 217from estimated population of 500 using the Krejcie & Morgan sample size table at 0.5% was used for the study. Findings show a positive but insignificant effect of the Finance Act on tax conflict minimization in Nigeria. It also showed that the Finance Act has a significant effect on prevention of incidence of double taxation in Nigeria. It was therefore recommended that government needs to adopt conscious efforts to amend all conflicting areas in the tax law, plug possible loopholes by continuously reviewing and updating tax legislations in line with international best practice to ensure that the right amount of tax is remitted to Government treasury; and there is need to also promote efficient tax administration using technology so as to help minimize reoccurring tax conflict between the tax authorities and the tax payers as well as prevent double taxation of taxpayers.
Does Poverty Matters in Maternal Health and Output Growth Nexus in sub-Saharan African Countries? A Panel ARDL Approach
Authors: Eleojo* Ebeh, Joy , Ariyo Awe, Abel,
Published: January 2023

This paper investigates the role of poverty in maternal health-output growth nexus in sub-Saharan African (SSA) countries. The study employs panel autoregressive distributed lag model (PARDL) and analysed a balanced panel data covering 21 countries from 1990 to 2018. The empirical results show that the coefficient on interaction between poverty and maternal health tend to be statistically significant both in the long run and short run. Although, the direction of the impact is positive in the long run but negative in the short run. This finding emphasizes that increased consumption expenditure reduces poverty which will in turn ameliorate maternal mortality rate leading to better maternal health in the long run.

Authors: Tochukwu Eze Kierian
Published: January 2023

The increased nature of uncontrolled fire disasters in Nigerian is an issue that calls for urgent attention on the responsiveness of the Nigerian fire service. With a focus on Anambra State – where fire disaster cases were recorded the most in the last decade in Nigeria – this research examined the correlation between employee remuneration and the poor responsiveness of the Anambra state fire service. Using the frequency percentage distribution table, data were presented and analyzed, while the hypotheses were tested using the mean method. The result shows that poor remuneration among other crucial factors is a causative of the poor responsiveness of the fire service and implicitly, increased uncontrolled fire disaster cases. Based on the findings, increased salaries and allowances of firefighters, creation and positioning of more fire stations, etc. was recommended to tackle the malaise and reduce uncontrolled fire disaster cases in the country.
THE AFRICAN UNION AS COLLECTIVE NORM ENTREPRENEUR IN STRATEGIC ENGAGEMENTS OF EXTERNAL POWERS AND AFRICA
Authors: BUTA Idris Yeba
Published: January 2023

Since 2000, both emerging powers like China and India and established powers like the EU and the US were voraciously seeking close relations with Africa, and the African Union was playing a coordinating role in managing the ensuing relationships. However, the role of the AU as a collective African norm entrepreneur has not been recognized due to the theoretical limitations imposed by the mainstream theories of IR. This study used ‘Subsidiarity Norm Theory’ to find out collective African agency in the progressively evolving relations using data collected from treaties, policy statements, press releases, other relevant documents, and policy actions. This study found that the AU was emerging as the premier norm entrepreneur in international politics of Africa despite the difficult challenges posed by factors such as limited organizational capacity, the opportunistic actions of some of its members, and interventions by external powers that encroach on its coordinating role. Actions of the AU and consequent intersubjectively evolving relations with emerging powers like China also reveal that the AU was both responding to emerging powers' policy initiatives and constituting the terms of the engagements.

Abstract. Logging of tropical primary forests is a widely acknowledged global issue threatening biodiversity hotspots and indigenous communities leading to significant land erosion and decreased soil stability. The downstream effects of logging on human coastal communities include poor water quality and increased sedimentation. Quantifying the impacts of historical deforestation within a watershed requires accurate data from river discharge or satellite images, which are rarely available prior to the 1980’s. In the absence of these in-situ measurements, proxies have successfully produced accurate, long-range, historical records of temperature, hydrological balance, and sediment discharge in coastal and oceanic environments. We present a 30 year, monthly resolved Ba/Ca proxy record of sediment in river discharge as measured from the skeletal remains of massive corals Porites sp. from northern Malaysian Borneo. We make the comparison with local instrumental hydrology data, river discharge and rainfall, to test the reliability of the Ba/Cacoral proxy. Our results show that averaging five records into two composites results in significant positive correlations with river discharge (r = 0.5 and r = 0.59) as well as a difference in correlations strength coherent with distance from the river mouth, with the composite closer to the river mouth displaying a higher correlation. More importantly, Porites sp. corals from this region recorded a very similar upward trend to that of river discharge on multi decennial time scales. The lack of similar increase, and overall stability in the precipitation record suggests that the river discharge’s trend recorded by corals is linked to the increasing land use associated with ever–growing deforestation. We argue that massive corals in this region are therefore valuable archives of past hydrological conditions and accurately reflect changes in land use patterns.

Abstract. The anthropogenic carbon distribution between the atmosphere, land surface and ocean varies significantly with the choice of scenario for identical changes in mean global surface temperature. Moving to a lower CO2 emissions scenario means that warming levels occur later, and with significantly less carbon in the three main carbon reservoirs. After 2 °C of warming, the multi-model mean ocean allocation can be up to 3 % different between scenarios, or 36 Pg in total with an even larger difference in some single model means. For the UKESM1 model, the difference between the minimum and maximum atmospheric fraction at the 2 °C Global Warming Level (GWL) is 3.6 %. This is equivalent to 50 Pg of additional carbon in the atmosphere, or the equivalent of five years of our current global total emissions. In the lower CO2 concentration scenarios, SSP1-1.9 and SSP1-2.6, the ocean fraction grows over time while the the land surface fraction remains constant. In the higher CO2 concentration scenarios, SSP2-4.5, SSP3-7.0 and SSP5-8.5, the ocean fraction remains constant over time while the the land surface fraction decreases over time. Higher equilibrium climate sensitivity (ECS) models reach the GWLs sooner, and with lower atmospheric CO2 than lower sensitivity models. However, the choice of scenario has a much larger impact on the percentage carbon allocation at a given warming level than the individual model's ECS.
A nonhydrostatic oceanic regional model, ORCTM v1, for internal solitary wave simulation
Authors: Huang Hao , Song Pengyang , Qiu Shi , Guo Jiaqi , Chen Xueen
Published: January 2023

Abstract. The Oceanic Regional Circulation and Tide Model (ORCTM), including a
nonhydrostatic dynamics module which can numerically reproduce internal
solitary wave (ISW) dynamics, is presented in this paper. The performance
of a baroclinic tidal simulation is also examined in regional modeling
with open boundary conditions. The model control equations are characterized by three-dimensional and
fully nonlinear forms considering incompressible Boussinesq fluid in
Z coordinates. The pressure field is decomposed into the surface,
hydrostatic, and nonhydrostatic components on the orthogonal curvilinear
Arakawa-C grid. The nonhydrostatic pressure determined by the intermediate
velocity divergence field is obtained via solving a three-dimensional
Poisson equation based on a pressure correction method. Model validation
experiments for ISW simulations with the topographic change in the
two-layer and continuously stratified ocean demonstrate that ORCTM has a
considerable capacity for reproducing the life cycle of internal solitary
wave evolution and tide–topography interactions.
Climate impacts of parameterizing subgrid variation and partitioning of land surface heat fluxes to the atmosphere with the NCAR CESM1.2
Authors: Yin Ming , Han Yilun , Wang Yong , Sun Wenqi , Deng Jianbo , Wei Daoming , Kong Ying , Wang Bin
Published: January 2023

Abstract. All current global climate models (GCMs) utilize only
grid-averaged surface heat fluxes to drive the atmosphere, and thus their
subgrid horizontal variations and partitioning are absent. This can result
in many simulation biases. To address this shortcoming, a novel
parameterization scheme considering the subgrid variations of the sensible
and latent heat fluxes to the atmosphere and the associated partitioning is
developed and implemented into the National Center for Atmospheric Research
(NCAR) Climate Earth System Model 1.2 (CESM1.2). Compared to the default
model, in addition to the improved boreal summer precipitation simulation
over eastern China and the coastal areas of the Bay of Bengal, the
long-standing overestimations of precipitation on the southern and eastern
margins of the Tibetan Plateau (TP) in most GCMs are alleviated. The
improved precipitation simulation on the southern margin of the TP is from
suppressed large-scale precipitation, while that on the eastern edge of the
TP is due to decreased convective precipitation. Moisture advection is
blocked toward the southern edge of the TP, and the anomaly of anticyclonic
moisture transport over northern China extends westward, suppressing local
convection on the eastern edge of the TP. The altered large-scale
circulation in the lower atmosphere resulting from anomalous heating and cooling
in the planetary boundary layer is responsible for the change in moisture
transport. The performance of other key variables (e.g., surface energy
fluxes, clouds and 2 m temperature) is also evaluated thoroughly using the
default CESM1.2, the new scheme and the scheme stochastically allocating
the subgrid surface heat fluxes to the atmosphere (i.e., without subgrid
partitioning included). This study highlights the importance of subgrid
surface energy variations and partitioning to the atmosphere in simulating
the hydrological and energy cycles in GCMs.

Partindo desse entendimento, percebemos que os emojis ganham função dêitica nas interações por WhatsApp. Para tratarmos dessa condição, partimos de exemplos de conversas obtidos através de conversas privadas e em grupo de WhatsApp. Nossos resultados iniciais apontam para usos dos emojis como dêiticos pessoais, sociais, de lugar e discursivos.
ENTRE A PRESCRIÇÃO E A CONTEXTUALIZAÇÃO:
Authors: Lima Santos Lanuza , Dos Passos Mendes Elisangela
Published: January 2023

Este artigo analisa o tratamento das “construções relativas” em livros didáticos do ensino médio. Fundamentado no referencial teórico da sociolinguística variacionista e nos estudos empíricos sobre o fenômeno, nosso objetivo é investigar em que medida a realidade heterogênea e variável do português brasileiro é considerada no ensino de sintaxe. Para tanto, são observados os três volumes da coleção Português: contexto, interlocução e sentido (Maria Luiza Abaurre, Maria Bernadete Abaurre e Marcela Pontara). Neste estudo, assumimos que a compreensão da diversidade linguística é basilar no ensino de português, uma vez que fornece subsídios para uma aprendizagem mais coerente e contextualizada. Parte-se do pressuposto de que os livros didáticos, no tratamento da variação, centralizam-se nos conceitos e descrições de usos variáveis do nível lexical. Dessa forma, negligenciam as contribuições da variação para o ensino de sintaxe.  Em linhas gerais, a análise da coleção de livros didáticos revelou o comprometimento das autoras em apresentar e discutir a variação linguística de modo direto e indireto. No entanto, os estudos da sintaxe partem de uma abordagem notadamente prescritivista e usos variáveis são tratados de modo superficial e como curiosidades acessórias.
VARIAÇÃO, PRECONCEITO LINGUÍSTICO E ENSINO: VELHOS PROBLEMAS, NOVAS HISTÓRIAS
Authors: BRANDÃO Silvia Maria , SENE Marcus Garcia de , BIAZOLLI Caroline Carnielli
Published: January 2023

Utilizamos, neste artigo, o conto “Fita verde no cabelo: nova velha estória”, de Guimarães Rosa, para estabelecer relações entre o que seriam, por um lado, caminhos “encurtosos” e velhos problemas e, por outro, caminhos “loucos e longos” e novas histórias, no que diz respeito à tríade variação, preconceito e ensino de língua portuguesa. Para isso, discutimos questões teóricas para contextualizar ambos os tipos de caminho, problematizar aspectos que pertencem aos caminhos “encurtosos” e evidenciar experiências dos caminhos “loucos e longos”. Esperamos, com as ideias aqui apresentadas, explicitar a potencialidade de caminhos “loucos e longos” para uma educação, verdadeiramente, (socio)linguística.
UM ESTUDO COMPARATIVO DA SEMIVOCALIZAÇÃO DA LATERAL /L/ EM ESCRITAS DE ALUNOS DE SÉRIES INICIAIS DE ESCOLA PÚBLICA E PRIVADA DE JABOATÃO DOS GUARARAPES-PE
Authors: Silva André Pedro da
Published: January 2023

Objetiva-se explicar e catalogar o fenômeno encontrado na escrita da semivocalização da lateral /l/ quando transformada em glide /w/ e expressa ortograficamente como vogal alta u, em posição de codas final e medial. O presente trabalho se debruçou sobre dados recolhidos na cidade de Jaboatão dos Guararapes, em Pernambuco - PE, em uma escola municipal de ensino público. Salienta-se que esse trabalho também apresenta um estudo comparativo entre os dados aqui levantados e os dados já analisados pelo REFALES em ensino privado, tecendo, assim, uma comparação. A metodologia deste trabalho baseia-se no método quantitativo-comparativo e apoiamo-nos teoricamente na Teoria da Linguística e da Variação Linguística e para tanto, utilizamos o arcabouço de Câmara Jr (1998); Faraco (2012); Hora (2006); Hora, Pedrosa e Cardoso (2010); Mollica (2003); Morais (2003, 2007); Zilles e Faraco (2015), dentre outros; na Psicogênese da Língua Escrita, com Ferreiro e Teberosky (1986), na Filosofia da Linguagem, com Azize (2012) e para apreensão dos resultados em Freire (1987). Os resultados aqui apresentados nos mostram que fatores sociais associam-se aos linguísticos, sendo esclarecedores o quantitativo que aponta para uma maior superação da variação em contexto privado e a revelação de dificuldades fonológicas no contexto público.
PROCESSO DE SÍNCOPE NO AGRESTE E LESTE ALAGOANO
Authors: Franca Santos Paloma Evelin , Almeida de Oliveira Almir
Published: January 2023

RESUMO: Este estudo investiga, sob a ótica da Sociolinguística Variacionista amparada nos pressupostos metodológicos (LABOV, 2008 [1972]; WEINREICH, HERZOG, LABOV, 2006; MEYERHOFF, 2006), o processo de síncope das proparoxítonas no Agreste e Leste de Alagoas. O estudo analisa dados de fala de 60 participantes distribuídos em 2 maiores cidades do estado de Alagoas/AL, Maceió e Arapiraca. As variantes foram classificadas por análise espectrográfica com o auxílio do Praat. Os dados foram analisados utilizando testes multivariados e regressão multinível. Conclui-se que há mudança linguística em direção à síncope das proparoxítonas e que o processo está relacionado a aspectos diatópicos. Conclui-se ainda que o processo é socialmente estigmatizado, visto que a escolaridade apresentou interação com uma variável social. Desse modo, vê-se que a síncope é influenciada pela interação entre escolaridade e cidade; demonstra-se que a localização geográfica influencia na probabilidade de síncope, bem como o contexto anterior, a classe morfológica das palavras e a ressilabação também favorecem o processo; todavia, o contexto seguinte, extensão da palavra, sexo/gênero, idade e altura da vogal desfavorecem o processo.
