دور هيكل راس المال في ربحية الشركات في ظل الازمات المالية
Authors: محمد أكرم أحمد , احمد رزگار علي 
Published: December 2024

هدفت هذه الدراسة اختبار دور هيكل رأس المال في ربحية الشركات المدرجة في سوق العراق للاوراق المالية في ظل الازمات المالية. ولغرض تحقيق هذا الهدف ومن خلال جمع البيانات المالية المنشورة لعينة متكونة من (31) شركة مدرجة في سوق العراق للاوراق المالية للفترة (2012 -2020)، قد تم استخدام أسلوب الانحدار المتعدد الحصين (Robust regression model) لاختبار الفرضيات بالاستعانة بتحليل السلاسل الزمنية للبيانات المقطعية وفق البرنامج الإحصائي(10- Eviews ). وتوصلت الدراسة الى نتائج مفادها: ان لهيكل رأس المال مقاسا بالرفع المالي أثر سلبي على الربحية، وعند استخدام مقياس نسبة الديون الى حقوق الملكية لهيكل رأ س المال أثر ايجابي على الربحية، وتبينت النتائج بان للمحددات الوسيطة من حجم الشركة ونموالشركة وهيكل الاصول ونسبة السيولة أثر متفاوت ايجابا أو سلبا على مؤشرات الربحية المتمثلة ب(العائد على الموجودات، العائد على حقوق الملكية وهامش صافي الربح). كما ان الازمات المالية لها تأثير سلبي على الربحية لعينة من الشركات المدرجة أثناء فترة الدراسة.
ومن أبرز توصيات الدراسة هي: العمل على اتاحة الفرصة للشركات لاستغلال الفرص الغير المستغلة من الاقتراض بسبب تدنى نسبة الرافعة المالية لتلك الشركات، وكذلك تبني سياسة التوسع حجم الشركة والعمل من أجل نموها بغية تقليص الكلفة والمصاريف وبالتالي ازدياد العائد المتوقع على الموجودات وتوفر العائد على حقوق الملكية والربح الصافي للشركة. كما وصى على ضرورة البحث عن العوامل الاقتصادية والمتغيرات الاخرى لديها علاقة بتحديد دور هيكل رأس المال في ربحية الشركات، لان العوامل الاقتصادية تختلف من بلد لاخرى في تأثيرها على الاداء المالي للشركات العاملة داخل البلد بعينها.

Study on optical fiber materials and loss-dispersion management optimization technique
Authors: Roy Chowdhury Prosenjit , Biswas Biloy , Das Mousumi , Biswas Bidisha , Pradhan Ayan Kanti 
Published: December 2024

Abstract
Loss and dispersion are the major issues that need to be optimized for sustainable and effective optical communication. The lowest loss wavelength and best dispersion-managed wavelength are partially conjugated by dispersion shifted fiber (DSF), dispersion flattened fiber (DFF), and different modulation techniques. In search of further simple and effective alternatives to compensate for both the loss and dispersion of optical fiber, we have considered some commercially available optical fiber friendly materials like pure SiO2, B2O3, P2O5 and GeO2 doped SiO2 along with some popular fluoride glass combinations known as ZBLAN, HBL, ABCY, ZBLA, ZBG. Our study on material dispersion of some pure and doped materials has brought out some exciting results regarding the optimized loss-dispersion conjugation. It is observed that the systematic applications of the compositions can replace the existing DSF and DFF. At the same time, the efficiency of DSF and DFF can be increased by using these fiber materials as well. The technique can be used to boost the efficiency of existing loss-dispersion management systems by selectively replacing the materials of those systems. Our significant report on the fundamental properties of various fibers and their materials has a visionary direction toward loss-dispersion management.

La inclusión a una comunidad de inteligencias. Apuntes para la reflexión a partir del ejemplo de los sordos
Authors: Benvenuto Andrea 
Published: December 2024

Desde fines del siglo XIX la historia de la educación de sordos ha estado regida por el principio de inclusión a la comunidad de ciudadanos a partir del acceso del sordo a la lengua vocal (oral y escrita). Casi dos siglos más tarde, un iletrismo generalizado en la comunidad sorda, muestra que la instrucción no les aseguró el pleno ejercicio de la ciudadanía. Si la proposición “los sordos son iletrados” queda sometida a la prueba de la experiencia pedagógica, los actos que los sordos realizan y que desarticulan las condiciones que los encierran en una identidad deficiente/iletrada implican un proceso de subjetivación política. Este texto se propone mostrar, a partir de tres ilustraciones, que las estrategias de elaboración y de transmisión de modos de decir, de modos de leer y de escribir inventadas por los sordos, no son tributarias del acceso a una lengua, sino el resultado de una relación de los sordos al mundo que parte del único principio que podemos erigir como principio irreductible, el de la inclusión a una comunidad de inteligencias.Palabras-claves: sordo; inclusión; subjetivación política; comunidad de inteligencias.The inclusion of a community of inteligencies. Notes for reflection following the example of the deaf.AbstractSince the late XIX century the history of deaf education has been guided by the principle of inclusion to the community of citizens from the access of deaf to the voice language (oral and written). Almost two centuries later, a widespread functional illiteracy in the deaf community, shows that the instruction is not assured them the full exercise of citizenship. If the proposition "the deaf are illiterate" is put to the test of teaching experience, acts performed and the deaf that dismantle the conditions that the identityenclosed in a poor / illiterate involve a process of political subjectification. This article aims to show, from three illustrations, development strategies and modes of transmission of words, ways of reading and writing invented by the deaf, are not tax access to a language, but the result of An account of the deaf to the world that part of the only principle that we can construct irreducible principle, the inclusion of the intelligence community.Key- words: deaf, inclusion, political subjectivity, intelligence community.

O trabalho resulta de pesquisa realizada, durante três anos, enfocando os três primeiros anos de escolaridade de crianças de classes populares em escola pública do estado do Rio de Janeiro. A coleta de dados foi feita a partir de observações, entrevistas com alunos e professores e da produção textual dos alunos. Buscou-se analisar os diferentes fatores que interferem nos processos de ensino/aprendizagem da língua materna e que resultam em diferentes graus de domínio da leitura e da escrita. Com base em Bakhtin e Lahire, foram elaboradas categorias teóricas que permitem analisar tanto a lógica da cultura escolar na compreensão e ação do se constitui em material de ensino/apren- dizagem, quanto os processos de interação verbal que propiciam o desenvolvimento de práticas discursivas direcionadas à promoção do letramento social.Palavras-chave: ciclos, leitura e escrita.Reading and writing: the way the school deals with the issue in the first years of Education.AbstractThis study is the result of a research carried out during two years on the first three school years of low-income children studying in public schools in the state of Rio de Janeiro. Data collection was made from observation, interviews with students and teachers, and texts produced by the students. We tried to analyze the several factors that interfere with the processes of teaching/learning of the mother tongue, and that result in different levels of mastering the ability to read an write. Based on Bakhtin and Lahire, we established theoretical categories which allowed the analysis not only of the logic of the school culture in understanding and acting upon what shall be taught, but also the processes of verbal interaction that allowed the development of oral practices directed to the promotion of the teaching/learning of the social ability to read and write.Key-words: cycles, ability to read and write.

Published: December 2024

O projeto, desenvolvido no Centro de Estudos de Educação e Saúde, Unidade Auxiliar da Faculdade de Filosofia e Ciências, UNESP, campus de Marília – SP, teve como objetivo realizar um estudo sobre a apropriação da escrita por crianças com Síndrome de Down. Foram participantes do projeto 5 crianças, na faixa etária de 10 a 13 anos de idade, em diferentes situações de escolarização. Como procedimento de pesquisa, foram realizadas intervenções pedagógicas semanais, com base na Teoria Histórico-Cultural. Inicialmente, o grupo apresentava dimensões diferenciadas de aproximação com o universo escrito. Foram observados avanços nas representações gráficas e nas tentativas individuais de escrita. Dois alunos passaram a construir pequenos textos, um se encontra no início da escrita alfabética e dois continuaram a apresentar dificuldades, aproximando-se da escrita de forma muito tímida, presos à formalidade escolar e necessitando de uma mediação direta para a constituição das palavras.Palavras-chave: Escrita, Síndrome de Down, Teoria Histórico-Cultural.Noticing about the writing appropriation in Down’s Syndrome childrenAbstractThe project, developed at the Health and Education Studies ́ Center, in the Unity of the Science and Philosophy’s College, UNESP, Marilia ́s campus, had as goal the development of a study about the appropriation of writing by children with Down ’s syndrome. Five children, from 10 to 13 years old, on different situations of scholar levels, were took part in the project. As research procedure, it was developed weekly pedagogical interventions, based on Historical-Cultural Theory. At the beginning, the group presented different dimensions of approximation with the writing universe. It was observed advances on the graphic representation and on the individual trials of writing. Two children began to build small texts, one of the children is on the beginning of the alphabetic writing and two other children continue to present difficulties, getting close of the writing in a very not comfortable way, stuck on the scholar formality and a direct mediation to the words constitution is needed.Keywords: Writing, Down ́s syndrome, Historical-Cultural Theory.

Authors: Voss Dulce Mari da Silva 
Published: December 2024

O objetivo central deste texto é analisar os discursos e o contexto político de produção dos textos oficiais referentes ao Plano de Desenvolvimento da Educação (PDE), lançado em 2007 pelo governo federal, utilizando ferramentas teórico-metodológicas da Abordagem do Ciclo de Políticas de Stephen Ball e seus colaboradores e da análise de discurso com base em Foucault. Busco descrever as circunstâncias políticas que influenciam a produção dos documentos e analisar os efeitos provocados pelas reformas na Educação Básica, como a produção dos discursos de responsabilização e mobilização social e das práticas gerencialistas e performativas que visam melhorar resultados no ensino, em termos de reprovação e evasão escolar e melhorar desempenhos dos alunos nas avaliações do MEC. Palavras-chave: reformas educacionais; contextos políticos; discursos.The Education Development Plan: contexts and discoursesAbstractThe main objective of this paper is to analyze the discourses and the political context of production of official texts related to the Education Development Plan (EDP), launched by the federal government in 2007, using both theoretical-methodological tools from Stephen Ball’s Policy Cycle Approach, and discourse analysis based in Foucault. I seek to describe the political circumstances that act in the production of the documents, and analyze the effects caused by reforms in Basic Education, as the production of discourses of accountability and social mobilization, and of managerialist and performative practices that aim at improving teaching results, in terms of school failure and evasion, as well as improving students' performances in the assessments promoted by MEC.

Investigation of the synergistic effect of ceftazidime-avibactam and aztreonam combination on carbapenem-resistant Klebsiella pneumoniae isolates with 3 different methods
Authors: Uzunöner Yasemin , Kansak Nilgün , Aksaray Sebahat 
Published: December 2024

AbstractTreatment options are limited for infections caused by carbapenem-resistant Klebsiella pneumoniae (CRKP) isolates due to the production of metallo-β-lactamase (MBL). The ceftazidime-avibactam (CZA)/ aztreonam (ATM) combination represents a new therapeutic approach in MBL-positive isolates. Our study aims to determine distribution of carbapenemase genes in CRKP isolates and to investigate the in vitro synergistic effect of the CZA/ATM combination.Our study included 48 CRKP strains isolated from various clinical samples. Identification was performed using MALDI-TOF MS (bioMérieux, France), and susceptibility was tested with Vitek-2 (bioMérieux). The susceptibility to CZA and ATM was determined using CZA 30/20 µg and ATM 30 µg (Oxoid™,UK) disks. Carbapenemase genes VIM, NDM, IMP, KPC, OXA-23, OXA-58, OXA-48, and OXA-51 were investigated in only 44 isolates using the Bio-Speedy Carbapenem resistance qPCR (Bioexen, Turkiye) kit. Synergy testing was evaluated with double disk diffusion, gradient strip (bioMérieux)/disk diffusion, and broth disk elution methods.Out of 48 carbapenem-resistant isolates, 40 (83.3%) isolates showed resistance to CZA and 46 (95.8%) to aztreonam. Synergy was detected with all three methods in all isolates identified as resistant to CZA, CZA-sensitive isolates were not included in this evaluation. The most frequently detected carbapenemase genes were NDM+OXA-48, found in 28 (63.6%) of the isolates.Although the NDM+OXA-48 coexistence predominates in our center, in vitro synergy between CZA and ATM was detected in all of CZA-resistant isolates. Performing the CZA+ATM synergy test and reporting the result is crucial for choosing appropriate treatment in CRKP infection.
