Los datos y el azar en el currículo de educación básica y bachillerato: reflexiones desde la perspectiva internacional
Authors: Inzunza Cazares Santiago , Rocha Ruiz Eneyda
Published: June 2021

En el presente trabajo analizamos contenidos, aprendizajes esperados y orientaciones didácticas del currículo de estadística y probabilidad en la educación básica y bachillerato en México, con el propósito de reflexionar y relacionar con algunos currículos y recomendaciones de organismos que promueven la educación estadística a nivel internacional. Analizamos también las ideas fundamentales de la estadística y su presencia en el currículo mexicano. Los resultados muestran que el estudio de los datos y el azar está presente desde preescolar hasta bachillerato. La metodología de enseñanza en educación básica otorga importancia a contextos reales y al planteamiento de preguntas estadísticas para responder con los datos, pero en bachillerato se hace mayor énfasis en el cálculo estadístico. La tecnología para análisis de datos y simulación está prácticamente ausente en el currículo de todos los niveles.
Prácticas de publicación en campos disciplinares percibidas por investigadores de una universidad pública mexicana
Authors: Méndez-Ochaita Margarita Flor , Carrasco Altamirano Alma , Serrano Acuña Mara
Published: June 2021

Este artículo revisa la publicación como práctica científica de comunidades disciplinares a través de unestudio empírico y exploratorio con 352 investigadores de una universidad pública estatal mexicana. Se aplicó una encuesta en línea para conocer las percepciones de los investigadores sobre el quehacer científico en sus campos disciplinares. En este trabajo se analizan las respuestas a los ítems relacionados con las prácticas de publicación (seis de un total de 41 ítems del instrumento). El enfoque es cualitativo y lainterpretación se fundamenta en los aportes clásicos de la sociología de la ciencia de Robert Merton sobrela estructura normativa que regula la actividad científica. Los resultados sugieren que entornos institucionales de exigencia para la producción académica en las disciplinas alimentan prácticas científicas variadas. La mayoría de investigadores percibe que en sus campos disciplinares se aprovecha tanto el conocimiento producido localmente como el extranjero, pero en todas las disciplinas hay una parte de la comunidad científica que percibe prácticas que están en tensión con las normas mertonianas, tales como: interesarse más por adquirir fama personal que por ampliar la base de conocimiento, incurrir en plagio, fragmentar de manera intencionada una investigación para construir varias publicaciones, y ejercer el rol de dictaminador anclado a creencias y opiniones personales por encima de valores universales de construcción del conocimiento científico. Esto tiene implicaciones para la formación de los aprendices de científicos que en el nivel de posgrado participan de las prácticas de los especialistas y se están preparando para escribir y publicar géneros textuales especializados como el artículo de investigación.
La motivación para el aprendizaje de segundas lenguas minorizadas: el caso del estudio de la lengua náhuatl por universitarios hispanohablantes
Authors: Figueroa-Saavedra Ruiz Miguel
Published: June 2021

Este artículo presenta un estudio sobre las motivaciones de hablantes de lenguas hegemónicas para aprender segundas lenguas minorizadas, centrándose en el caso de la lengua náhuatl. Se analizaron dos situaciones: una donde el náhuatl es considerado una lengua extranjera y en otra una lengua nacional, para identificar la asociación de motivos con determinados contextos. Los resultados muestran que los motivos instrumentales tienen mayor peso que los integradores, aun predominando factores intrínsecos. Esto es así porque el náhuatl no se visibiliza o percibe como una lengua hablada en el contexto social y académico del aprendiente, y porque las ideologías lingüísticas hispanocéntricas predominantes tienden a remarcar su valor en su sentido histórico o ideológico nacionalista, de modo que la orientación integradora responde más al deseo de incorporarse a una comunidad imaginada nacional o profesional que a querer contactar o ser parte de la comunidad nahua. Por tanto, el aprendiente valora el aprendizaje del náhuatl más como conocimiento que como medio de comunicación o integración.

En este texto se ha pensado la sociedad moderna-contemporánea, para lo cual se acudió al asunto de la educación. En otras palabras, el escrito hace una reflexión social y política del presente a través de la temática educativa. Por otro lado, el artículo se sostiene en una perspectiva interdisciplinar en tanto que confluyen saberes filosóficos, jurídicos, antropológicos y sociales, los cuales se encargan de analizar la sociedad y la educación. Asimismo, lo que se ha escrito busca contribuir en los estudios que señalan el factor político de la educación, de ahí que el saber se relaciona con el poder, puesto que los que generan y significan el espacio-tiempo también lo dirigen.
Validación del Cuestionario de Estilo Atribucional Académico para el diagnóstico de ingreso a la Educación Superior
Authors: Becerra González Cruz Edgardo , Plata Vivanco Adriana
Published: June 2021

Las universidades buscan caracterizar a sus estudiantes para prevenir que abandonen la escuela y así, posibilitar su egreso. Entre las variables que se diagnostican y se relacionan con el rendimiento, éxito y trayectoria escolar, están las cognoscitivo-motivacionales: autoestima, autoconcepto y motivación (Pool-Cibrián, Martínez-Guerrero, 2013). Estas variables se construyen a partir de otra: el estilo atribucional, o cómo define la forma en que la persona interpreta lo que le sucede; el académico se refiere a la manera en que un estudiante interpreta lo bueno y lo malo que le ocurre en la escuela o en relación con su aprendizaje (Petri, Govern, 2015).

El objetivo del presente estudio fue adaptar el Cuestionario de Estilo Atribucional Académico (
CEAA
), en una población de estudiantes preuniversitarios. El instrumento se adaptó y aplicó a aspirantes para el ingreso a una universidad de la Ciudad de México. En los resultados se observó que los reactivos del cuestionario se organizaron en cuatro factores, de forma coincidente con la propuesta de Peterson et al. (1982), fundamento empírico del instrumento. Se encontró que los factores cuentan con un alpha de Cronbach a>0.75. En futuras investigaciones se podría probar su validez concurrente, comprobar otros modelos factoriales y determinar su validez predictiva respecto del rendimiento escolar.

En este escrito desarrollamos el marco conceptual de un proyecto de investigación colaborativa denominado Prácticas de Lectura y Escritura con Potencial (Trans)Formativo, para lo cual explicamos primero la perspectiva que se asumió al inicio del proyecto y sus transformaciones a lo largo de tres años de trabajo exploratorio. A continuación, analizamos cuatro prácticas (trans)formativas, ubicadas en ámbitos diversos de la Ciudad de Buenos Aires. Hemos identificado estas prácticas porque, tomadas en su conjunto, nos permiten: a) mostrar la noción de potencial transformativo cuando se lo piensa ligado a prácticas de lectura y escritura; b) describir y analizar la centralidad que ocupan el leer y el escribir en espacios, organizaciones e institucionalidades muy diferentes entre sí, pero que tienen en común un potencial para interpelar el orden dado y transformarlo, y c) hacer visible cómo estas prácticas fueron apelando a diversos formatos, soportes, disciplinas y lenguajes, y al hacerlo, reconfiguraron el mismo sentido de leer y escribir. En la sección final subrayamos los alcances de nuestro estudio en tanto los análisis de experiencias singulares nos permiten arribar a conclusiones en relación con el potencial transformativo de la lectura y la escritura. Asimismo, dejamos planteadas algunas limitaciones del estudio realizado e interrogantes para desarrollo futuro.
Deformation of a cantilever curved beam with variable cross section
Authors: Escedi István , Baksa Attila
Published: June 2021

This paper deals with the determination of the displacements and stresses in a curved cantilever beam. The considered curved beam has circular centerline and the thickness of its cross section depends on the circumferential coordinate. The kinematics of Euler-Bernoulli beam theory are used. The curved elastic beam is fixed at one end and on the other end is subjected to concentrated moment and force; three different loading cases are considered. The paper gives analytical solutions for radial and circumferential displacements and cross-sectional rotation and circumferential stresses. The presented examples can be used as benchmark for the other types of solutions as given in this paper.
The average method is much better than average
Authors: Boda Lívia , Faragó Istvan , Kalmár-Nagy Tamás
Published: June 2021

Operator splitting is a powerful method for the numerical investigation of complex time-dependent models, where the stationary (elliptic) part consists of a sum of several structurally simpler sub-operators. As an alternative to the classical splitting methods, a new splitting scheme is proposed here, the Average Method with sequential splitting. In this method, a decomposition of the original problem is sought in terms of commuting matrices. Wedemonstrate that third-order accuracy can be achieved with the Average Method. The computational performance of the method is investigated, yielding run times 1-2 orders of magnitude faster than traditional methods.

The ranking and systematic improvement of mathematical models based on objective criteria are described and illustrated by an example. The methodology outlined in this paper provides a framework for the evolutionary development of a large class of mathematical models.
Financial and Credit Instruments in the Local Structural Policy of Urban Development in the Western Region of Ukraine
Authors:   Institute of Regional Research named after M. I. Dolishniy of the NAS of Ukraine, Syniura-Rostun N. R.
Published: June 2021

The article discloses the peculiarities of the use of financial and credit instruments, in particular local borrowings, in the local structural policy. It is identified that the task of local self-government bodies of cities is to form their own local structural policy, which would focus on innovative, technological and inclusive development. The implementation of such a policy requires the use of a number of instruments, including budget, investment, financial and credit, grant, marketing and management, tax, etc. An important place is given to financial and credit instruments, as they allow attracting additional financial resources for the development of the city economy. Among the financial instruments, the author examines local borrowings, including bond loans and local guarantees. Bond loans have not become a common insrtument for attracting financial resources, which is associated with a number of obstacles to their issue. Among the cities of the Western region of Ukraine, only Lviv and Ivano-Frankivsk issued bonds for the period of 2015–2020. It is determined that local borrowing also does not play a significant role in the formation of the cities’ financial resources due to the low creditworthiness of the latter, as well as the complex procedure for obtaining. The instrument of local guarantees enables local self-government bodies to implement projects for the development of communal infrastructure and resource saving. Due to legislative restrictions, local self-government bodies cannot use local borrowings to implement local structural policies by supporting strategic sectors of the local economy. The full use of this instrument in local structural policy requires amendments to the legislation that would give greater autonomy to local self-government bodies and create opportunities for increasing the competitiveness of the urban economy.

The Essential Techniques Affecting the Performance of Sudanese EFL Learners in Writing: A Case Study of Three Eastern Universities of Sudan
Authors: Ali Suad Abdelwahid Fadlallah
Published: June 2021

This paper explores the English language learners’ weakness in writing because most of them do not know how to combine their sentences correctly. The paper was devoted to Sentence Combining (SC) as an essential technique or method that affects EFL learners' performance in writing English. Using the case study on fourth-level students majoring in English, the descriptive-analytical method has been applied, representing the three eastern universities in Sudan: The University of Kassala, University of Gadarif and Red Sea University. The researcher used an objective test of (83) items in Sentence Combining in English. The frequency tables and percentage were used for the five areas in the students' test (pass-fail). According to the students' outcomes, they have been proved that the Sudanese learners of English at the three eastern universities lack the awareness of methods and techniques of combining English sentences. They are not well-informed of combining English sentences by means of punctuation, co-ordination, subordination, reduction and apposition. The concept of sentence combining is unconsciously neglected by the teachers themselves, who are unaware of its importance.

Published: June 2021

Teaching writing has always been a more challenging task for EFL teachers as a result of its innate structural complexities and the linguistic sophistication required to accomplish writing. The pandemic and the resultant online teaching has made it even more challenging. Motivating the students, making the online classes interesting and maintaining the efficacy of the offline classes are some of the daunting tasks that stare at the EFL teachers at this juncture. With a view to addressing these problems, UTAS-Salalah and Ibra jointly conducted a webinar i.e. Teaching Writing Using Internet Tools for the teachers. The online platforms and tools discussed during the webinar, the literature survey, and the participants' feedback form the core of this research paper. The literature survey deals with both the problems of teaching writing and the problems of teaching it online. Then, it also discusses various online tools suggested by other researchers to make teaching writing more effective and fruit-bearing. A feedback questionnaire with Likert scale has been used to measure the efficacy of the proposed tools. The findings appear to confirm the usefulness of the said tools in teaching writing from the teachers' point of view.

Authors: Wahyuni Rosi , Syamsi Kastam
Published: June 2021

This research aims to find out the critical discourse analysis in the text of speeches from Nadiem Makarim and Muhadjir Effendy. The speech was chosen because it is one of the objects in Critical Discourse Analysis (CDA). Critical Discourse Analysis (CDA) is an approach to analyse the relationship between language, ideology, and power. This research used the descriptive qualitative method. The researcher uses the three-dimensional framework by Norman Fairclough in analysing the data of Critical Discourse Analysis (CDA). In presenting and analyzing the data, the researchers used qualitative data analysis theory from Miles and Huberman (1994) in Gani (2011), consisting of data reduction, data display or representation, and conclusion drawing or verification. The result of this study shows that both the script of speeches from Nadiem Makarim and Muhadjir Effendy have micro, mezzo, and macro-level related to the framework of Norman Fairclough. The language used in both of the speeches is a standard language, but in the speech of Nadiem Makarim used more creative language that can touch the millennial generations, while in the speech of Muhadjir was the usual words that can make the audiences bored.
Review of the Classroom Implications Discussed in Language and Cultural Practices in Communities and Schools: Bridging Learning for Students from Non-Dominant Groups Edited by Inmaculada García-Sánchez & Marjorie Faulstich Orellana
Authors: Karami Amirreza
Published: June 2021

This review provides a summary of the classroom implications discussed in Language and Cultural Practices in Communities and Schools: Bridging for Students from Non-Dominant Groups edited by Inmaculada García-Sánchez and Marjorie Faulstich Orellana (2019). Although there are thirteen chapters in this book written by different scholars, they are related to each other and provide teachers with some research-based guidelines on how to integrate different sources of knowledge—such as students’ funds of knowledge—into their instructions in multicultural classrooms. The review of the classroom implications discussed in this book highlights the important role of the teacher once more in providing minority students with the equitable education that they deserve. Therefore, teachers need to be familiarized with culturally responsive teaching approaches in general and, in particular, with different teaching methods and strategies of multicultural education. This will allow teachers to prepare their students to live successfully and peacefully in non-native cultural settings and societies.
Lexical Variations in Pakistani English: A Case Study of the Novel Twilight in Delhi
Authors: Sarfraz Maha
Published: June 2021

The present study investigates the English language variations due to code-switching between L1 (Urdu) and L2 (English). It shows how language varies from culture to culture, religion to religion, and how these variations make language an independent variety. This research also investigates the role of Urdu language in the formation of Pakistani English.  It is a corpus-based study. Methodology in the study is both qualitative and quantitative. A mixed approach has been employed. As a sample, a famous postcolonial novel “Twilight in Delhi” by Ahmed Ali has been selected. Analysis shows that the Pakistani native language has an effect on its culture on the English language. This research also investigates various sociolinguistics factors. It shows that the phenomenon of “Borrowing” is frequently used in the novel than compounding and hybridization because of the Islamic religion, historical and societal culture. Edibles are transferred from Urdu into English because they do not have their direct equivalents in English. The results also indicate that the usual use of Urdu words into English at the lexical level is property of Pakistani English and makes it an independent variety.

Authors: Shitu Sabiu , Attahiru M. , Iliya F. A.
Published: June 2021

The antibacterial activity of Tokar sha; a local traditional medication widely used by many people in North-west zone of Nigeria especially Sokoto, Kebbi and Zamfara against enteric infections were examined against some clinical isolates of pathogenic bacteria (Staphylococcus aureus, Escherichia coli, Bacillus cereus and Salmonella typhi) using agar well diffusion method. The pattern of inhibition varied with the tokar sha concentrations and the organisms tested. The tokar sha was more effective on E. coli with a maximum zone of growth inhibition of 25mm at 35mg/ml followed by B. cereus (20mm). However, S. aureus and S. typhi were resistant to tokar sha at all concentrations tested. The minimum inhibitory concentrations (MIC) were found to be 35mg/ml for both E. coli and B. cereus. The antibacterial activities exhibited by tokar sha in this study could be attributed to the presence of its constituents which signifies the potential of the tokar sha as a therapeutic agent. These findings may justify the ethnomedicinal use of tokar sha as an antibacterial agent against enterobacteria

Authors: Kabiru Umar , Muhammad Abubakar
Published: June 2021

User-based and item-based collaborative filtering techniques are among most explored strategies of making products’ recommendations to Users on online shopping platforms. However, a notable weakness of the collaborative filtering techniques is the cold start problem. Which include cold user problem, cold item problem and cold system problem – i.e., the failure of collaborative filtering to make recommendation of products to a new user, failure of an item to be recommended, or combination of the two respectively.  Literature investigation has shown that cold user problem could be effectively addressed using technique of personalized questionnaire. Unfortunately, where the products’ database is too large (as in Amazon.com), results obtained from personalized questionnaire technique could contain some user preference uncertainties. This paper presents technique of improving personalized questionnaire with uncertainty reduction technique. In addition, the paper presents classification of product recommendation systems. In this work we will be limited to user-based cold start.  Experimentation was conducted using Movielens dataset, where the proposed technique achieved significant performance improvement over personalized questionnaire technique with RMSE, Precision, Recall,1 and NDCG of 0.200, 0.227, 0.261, 0.174 and 0.249

In the third part of this article, an attempt is made to expand the range of regulation of the steam generator load from 40% to 100% by injecting recirculating flue gases taken after the water economizer into the middle radiation part of the furnace. For this, verification thermal calculations of the boiler were carried out when burning ДГ-100 coal in a wide range of variation of the recirculation coefficient Krec = 10−20% at loads of 40% and 50% of the nominal. It is shown that: a) at a load of 50%, recirculation of flue gases Krec = 13 % leads to a drop in the steam temperature along the primary path, due to which the maximum wall temperatures of all-welded screens decrease, which makes it possible to reduce the cost of boiler manufacture by reducing the use of expensive austenitic steels by 116.3 t; b) to ensure a live steam temperature of 600 °С at a load of 40%, it is necessary that Krec = 12%. This leads to a rise in the cost of the boiler in comparison with the load of 50% due to the use of steel grade 10X16N16V2MBR in the manufacture of ceiling screens. Bibl. 3, Fig. 17, Tab. 4.

Introdução: A mobilização precoce é uma técnica, que pode facilitar a realização dos autocuidados, promovendo ganhos em força muscular e um aumento do grau de independência, reduzindo consequentemente, o tempo de internamento assim como, os custos inerentes a ele.
Objetivos: Identificar através de um estudo de revisão sistemática da literatura os benefícios da mobilização precoce em doentes de cuidados intensivos.
Metodologia: Realizou-se uma revisão sistemática da literatura baseada na metodologia proposta pelo Joanna Briggs Institute. A pesquisa foi realizada nas bases de dados MedLine®, CINAHL®, PubMed ® considerando como critérios de inclusão estudos publicados nos últimos 10 anos. Foram utilizados os instrumentos da JBI para avaliação metodológica dos estudos.
Resultados: Foram incluídos 5 estudos, de um total de 160 artigos identificados A inatividade prolongada leva a inúmeras complicações, nomeadamente cognitivas, funcionais e emocionais, que através da mobilização precoce podem ser minimizadas e/ou evitadas.
Conclusão: Através da análise dos artigos verificamos que a mobilização precoce reduz o tempo de internamento e evita complicações e permite ganhos em saúde. Contudo, foram identificadas algumas barreiras tais como a carga de trabalho dos enfermeiros, a pouca clareza quanto à responsabilidade da mobilização, os riscos de lesões da equipa, a motivação do doente e a participação da família que fragilizam a mobilização precoce.

Introdução: Prestar cuidados à pessoa com dependência pode ser extremamente difícil e desgastante a vários níveis, onde a sobrecarga inerente à movimentação manual do doente, poderá ocasionar má postura e consequentemente lesões músculo-esqueléticas, no cuidador informal.
As lesões músculo-esqueléticas, ao serem consideradas um problema de saúde multifatorial, tornam-se uma prioridade de atuação da Enfermagem de Reabilitação, onde os cuidadores informais de doentes dependentes no domicílio merecem especial atenção.
Esta pesquisa teve como objetivo capacitar os cuidadores informais de doentes dependentes no domicílio, para a aplicação das medidas preventivas de lesões músculo-esqueléticas, inerentes à execução da movimentação manual do doente dependente, no domicílio.
Metodologia: metodologia de projeto. O diagnóstico de situação realizou-se através de uma entrevista estruturada. Para a observação da aplicação de medidas preventivas de lesões músculo-esqueléticas, aplicou-se uma grelha de observação de comportamentos, com vinte itens, antes e após a realização de duas formações teórico-práticas sobre procedimentos preventivos de lesões músculo-esqueléticas, no contexto natural da prestação de cuidados.
Resultados: A amostra deste estudo foi constituída por dez cuidadores informais. Todos os participantes pertenciam ao género feminino, com idade média de 53 anos; 80% não possuíam sintomatologia músculo-esquelética antes de começar a cuidar; 100% não evitava esforços bruscos, nem a utilização dos músculos das costas e não executava exercícios de alongamento. Após sessões verificou-se a melhoria em relação a quinze dos vinte itens observados.
Conclusão: Este estudo realça a relevância da intervenção da Enfermagem de Reabilitação, na capacitação dos cuidadores informais de doentes dependentes no domicílio, na prevenção das lesões do sistema músculo-esquelético.

Introdução: Com o aumento da longevidade e declínio da função física, psicológica e social dos idosos é essencial perceber as condições sociodemográficas e de saúde que concorrem para a fragilidade.
Objetivos: Analisar o perfil de fragilidade dos idosos de uma unidade de saúde do norte de Portugal.
Metodologia: Estudo descritivo, transversal com 173 idosos a residir no domicílio e inscritos numa Unidade de Saúde. Como instrumento de recolha de dados usou-se um inquérito, realizado por telefone, contendo dados sociodemográficos, de saúde e o Índice de fragilidade de Tilburg (TFI).
Resultados: Amostra predominantemente feminina com idade média de 81,11 anos, maioritariamente casados, com diversas comorbilidades e polimedicados. A representação da fragilidade foi de 60,7%, estando essa condição significativamente associada ao género, estado civil, número de doenças crónicas, polimedicação e autoperceção da saúde. Para a maioria dos idosos (83,8%), a condição de fragilidade é influenciada cumulativamente pelas dimensões físicas, psicológicas e sociais.
Conclusão: A fragilidade é uma condição prevalente e o perfil está associado a um conjunto de caraterísticas nas quais é possível intervir retardando a progressão da fragilidade que ocorre com o envelhecimento.
