Bilateral Occlusive Retinal Vasculitis in a Patient with Dermatomyositis
Authors: Loporchio Dean , Gealy Daniel , Yilmaz Taygan , Barton Andrew T. , Thakuria Pranjal , Janigian Robert
Published: May 2023

A 48-year-old woman with a history of dermatomyositis (DMS) presented with 2 weeks of worsening myalgias, weakness, and diffuse edema following cessation of her systemic immunosuppression and subsequently developed severe bilateral vision loss consistent with bilateral frosted branch angiitis. Multimodal imaging was performed, and the patient was successfully treated with pulse-dose steroids and intravenous immunoglobulin, as well as intravitreal aflibercept. Ophthalmic involvement of DMS is typically limited to episcleritis, conjunctivitis, and uveitis. We present an uncommon case of bilateral occlusive retinal vasculitis with frosted branch angiitis in a patient with DMS. The significant improvement anatomically and in visual acuity in our patient suggests a role of combined anti-vascular endothelial growth factor and systemic immunosuppression in the management of DMS -related frosted branch angiitis. We suggest that retinal vasculitis should be considered in patients with known DMS and acute vision loss, with prompt referral for ophthalmologic evaluation.

Published: May 2023

Purpose In patients with epidermal growth factor receptor (EGFR)-mutant non–small cell lung cancer (NSCLC), EGFR tyrosine kinase inhibitors (TKIs) improve response rate and survival. However, most patients eventually develop resistance. This study aimed to identify the role of CD73 in EGFR-mutant NSCLC and explore whether CD73 inhibition may serve as a therapeutic strategy in NSCLC patients with acquired resistance to EGFR-TKIs.Materials and Methods We evaluated the prognostic role of CD73 expression in EGFR-mutant NSCLC using tumor samples from a single institution. We silenced CD73 in EGFR-TKI–resistant cell lines using short hairpin RNA (shRNA) targeting CD73 and also transfected a vector alone as a negative control. Using these cell lines, cell proliferation and viability assays, immunoblot assays, cell cycle analysis, colony-forming assays, flow cytometry, and apoptosis analysis were performed.Results High expression of CD73 was associated with shorter survival in patients with metastatic EGFR-mutant NSCLC treated with first-generation EGFR-TKI. CD73 inhibition synergistically inhibited cell viability with first-generation EGFR-TKI treatment compared with the negative control. When CD73 inhibition and EGFR-TKI treatment were combined, G0/G1 cell cycle arrest was induced through the regulation of p21 and cyclin D1. In addition, the apoptosis rate was increased in CD73 shRNA-transfected cells treated with EGFR-TKI.Conclusion High expression of CD73 adversely affects the survival of patients with EGFR-mutant NSCLC. The study demonstrated that inhibiting CD73 in EGFR-TKI–resistant cell lines resulted in increased apoptosis and cell cycle arrest, which overcame the acquired resistance to first-generation EGFR-TKIs. Further research is needed to determine whether blocking CD73 plays a therapeutic role in EGFR-TKI–resistant patients with EGFR-mutant NSCLC.
Curvature of the second kind and a conjecture of Nishikawa
Authors: Cao Xiaodong , Gursky Matthew J. , Tran Hung
Published: May 2023

In this paper we investigate manifolds for which the curvature operator of the second kind (following the terminology of Nishikawa (1986)) satisfies certain positivity conditions. Our main result settles Nishikawa’s conjecture that a manifold with positive curvature operator of the second kind is diffeomorphic to a sphere, by showing that such manifolds satisfy Brendle’s PIC1 condition. In dimension four we show that curvature of the second kind has a canonical normal form, and use this to classify Einstein four-manifolds for which the curvature (operator) of the second kind is five-non-negative. We also calculate the normal form for some explicit examples in order to show that this assumption is sharp.
Hofer's metric in compact Lie groups
Authors: Larotonda Gabriel , Miglioli Martín
Published: May 2023

In this article, we study the Hofer geometry of a compact Lie group

K

which acts by Hamiltonian diffeomorphisms on a symplectic manifold

M

. Generalized Hofer norms on the Lie algebra of

K

are introduced and analyzed with tools from group invariant convex geometry, functional and matrix analysis. Several global results on the existence of geodesics and their characterization in finite-dimensional Lie groups

K

endowed with bi-invariant Finsler metrics are proved. We relate the conditions for being a geodesic in the group

K

and in the group of Hamiltonian diffeomorphisms. These results are applied to obtain necessary and sufficient conditions on the moment polytope of the momentum map, for the commutativity of the Hamiltonians of geodesics. Particular cases are studied, where a generalized non-crossing of eigenvalues property of the Hamiltonians hold.
On additive bases in infinite abelian semigroups
Authors: Bienvenu Pierre-Yves , Girard Benjamin , Lê Thái Hoàng
Published: May 2023

Building on previous work by Lambert, Plagne and the third author, we study various aspects of the behavior of additive bases in infinite abelian groups and semigroups.
We show that, for every infinite abelian group

T

, the number of essential subsets of any additive basis is finite, and also that the number of essential subsets of cardinality

k

contained in an additive basis of order at most

h

can be bounded in terms of

h

and

k

alone.
These results extend the reach of two theorems, one due to Deschamps and Farhi and the other to Hegarty, bearing upon

\mathbf{N}

.
Also, using invariant means, we address a classical problem, initiated by Erdős and Graham and then generalized by Nash and Nathanson both in the case of

\mathbf{N}

, of estimating the maximal order

X_T(h,k)

that a basis of cocardinality

k

contained in an additive basis of order at most

h

can have.Among other results, we prove that

X_T(h,k)=O(h^{2k+1})

for every integer

k \ge 1

. This result is new even in the case where

k=1

. Besides the maximal order

X_T(h,k)

, the typical order

S_T(h,k)

is also studied.
Our methods actually apply to a wider class of infinite abelian semigroups, thus unifying in a single axiomatic frame the theory of additive bases in

\mathbf{N}

and in abelian groups.
Medios técnicos en la producción de programas de radio
Authors: Rodríguez Borges Rodrigo Fidel
Published: May 2023

Decía Arthur C. Clarke que toda tecnología suficientemente avanzada es indiscernible de la magia. Probablemente sea inevitable que con frecuencia nos sintamos embargados por un pesimismo semejante en un mundo como el nuestro, sometido a tantos y tan profundos cambios. Los medios de comunicación en general y, en especial, los audiovisuales, vienen soportando en los últimos años las tensiones derivadas del proceso de innovación tecnológica profunda que está sacudiendo a las empresas de la comunicación y a sus usuarios. Esta situación emergente que estamos viviendo supone, a no dudarlo, un desafío muy especial para los profesionales de la información, que se ven impelidos a readaptar sus rutinas profesionales y a incorporar a su práctica profesional diaria unos instrumentos tecnológicos cada vez más sofisticados. Como ocurre con la prensa y con la televisión, también la radiodifusión y sus profesionales deben arrostrar el reto de la aceleración tecnológica en los últimos años de este siglo. Podría pensarse que los periodistas de radio -que son los profesionales que aquí tomaremos como referencia- no verán afectados sus hábitos de trabajo, pues su ocupación seguirá siendo "salir a la calle, ver lo que pasa y contarlo". Sin embargo, cuando ese salir a la calle, ver y contarlo, está afectado por un conjunto de dispositivos de mediación técnica, la obligación del profesional es conocer y manejar esas herramientas; bien es verdad que no con la perspectiva del técnico especialista, pero sí con la conciencia clara de que determinados instrumentos cumplen una función determinante en la producción de programas de radio. Con esa perspectiva, describimos en esta comunicación los dispositivos técnicos de un estudio de radio convencional, en la idea de que es precisamente el estudio el centro neurálgico de la producción radiofónica y, en una segunda parte, recapitularemos algunas de las innovaciones tecnológicas más importantes que se están produciendo en la radiodifusión y sus efectos en la labor periodística.
Orientación social de marca y su relación con comportamientos de engagement en clientes. Un estudio de caso
Authors: Mejía Giraldo Juan F. , Delgado Figueroa Lina Vanessa
Published: May 2023

Introducción: el objetivo del artículo fue analizar la relación entre la orientación social de marca y los comportamientos de engagement lealtad y recomendación en clientes. Metodología: se realizó un estudio de caso, a partir de un método mixto de investigación. Como técnicas de recolección de información, se llevó a cabo, en primer lugar, un análisis documental de dos canales de comunicación oficiales de la entidad estudiada, con la intención de identificar si la orientación social era un factor característico de su identidad de marca. Posteriormente, por medio de una encuesta se indagó el reconocimiento que tienen los clientes de los atributos y valores de la marca, los cuales fueron identificados en el análisis previo. Finalmente, se procedió con esta misma técnica a determinar si la orientación social de marca tenía relación con los comportamientos de engagement lealtad y recomendación. Resultados: se identifica que la marca destaca su orientación social como un rasgo fundamental de su identidad, aspecto que es reconocido por un 60% de los participantes. A su vez, se evidencia que los encuestados que consideraban relevante esta orientación social para configurarse como clientes presentan una mayor disposición a mantener un vínculo comercial con la entidad y a recomendarla. Conclusiones: por medio de la prueba CHI-CUADRADO se pudo corroborar que existe una dependencia entre la variable orientación social de marca y el engagement en clientes, por lo cual, generar valor a partir de este aspecto ejercería un efecto en el estímulo de compromiso en consumidores/usuarios desde la noción de reciprocidad

Engineering Design and Children: A Systematic Literature Review
Authors: Ehsan Hoda , Quintana-Cifuentes Jenny Patricia , Purzer Senay , Rehmat Abeera P.
Published: May 2023

Over the last two decades, a remarkable number of studies have examined the role of engineering education in supporting knowledge and skill building among children. In this paper, we present a synthesis of this literature to evaluate the added value of pre-college engineering design experiences at the elementary level, and ways researchers have gathered evidence of children’s development of this knowledge and skills. We have conducted a systematic literature review. The initial search across four different databases with relevant keywords resulted in over 3000 journal articles and conference papers. In a two-rounds screening, by applying the inclusion criteria first to titles and abstracts, and then to the full text, 78 peer-reviewed publications were included in this systematic literature review. We summarized and synthesized empirical evidence of student learning and engagement in engineering design activities, and approaches they were assessed and elicited. The thematic analysis revealed five categories of knowledge and skills: (1) disciplinary content knowledge; (2) engineering design practices, (3) engineering thinking skills; (4) professional skills; and (5) career awareness. Additionally, the assessment and evaluation approaches that were used for each of these categories were identified and discussed. The findings provide collective evidence of variety in student learning opportunities but also suggest the need to carefully define these knowledge and skills. Since a wide range of evaluation approaches were used to capture similar outcomes, we conclude that it is imperative to develop a shared research agenda by carefully defining the knowledge and skills we expect children to learn.
Predicting Student Success in Co-remediated General Education Mathematics Courses at a Large Urban Public University
Authors: Miller Kirsten L. , Suaray Kagba N.
Published: May 2023

Placement and support of students in first-year mathematics courses at institutions of higher education has long been a consequential issue. In a bid to address it, many systems and institutions of higher learning have elected to implement a co-remediation framework in place of pre-remediation, due in large part to the prohibitive cost of the latter, both in terms of financial resource, as well as student academic progress. Accompanying this evolution has been the expansion of the introductory mathematics curriculum beyond algebra to include statistics and quantitative reasoning. The present study discusses three distinct introductory mathematics courses at a large urban public M.S. granting institution in the U.S., with the goal of identifying the characteristics that correlate with success in each. Conditional probability and non-completion rate analyses were implemented to compare student performance in each course. Predictive models were then trained and validated, building insight concerning the differential relationships of demographic and academic covariates with course completion.
Research Trends and Issues of Engineering Design Process for STEM Education in K-12: A Bibliometric Analysis
Authors: Ali Muhammad , Tse Alex Wing Cheung
Published: May 2023

The study performed a bibliometric analysis on research literature related to ‘engineering design process’ (EDP) that has emerged as a popular approach for STEM education in K-12. The literature comprised 142 journal articles published from 2011 to 2021. There are three objectives of the study. Firstly, to identify the leading research trends of EDP for STEM education that have developed since the release of A Framework for K-12 Science Education in 2011. This framework is pivotal as it paved the way for the establishment of the Next Generation Science Standards in the United States. Secondly, to discern possible research issues on the aforesaid topic by analyzing the research trends. Lastly, to identify publications and authors that have generated prominent citation impact. Since EDP is an emergent approach for STEM education, fulfilling these three objectives can be conducive in facilitating future researchers to build upon the past foundation of research. In this study, the bibliometric data was identified and exported from Web of Science Core Collection: a database with rich scientific literature. The results identified major research trends and issues on EDP pertaining to professional development, design thinking and computational thinking, STEM competencies, scientific inquiry, and gender gaps in STEM education.

Authors: Cornito Celinmar M.
Published: May 2023

The achievement of pupils in their future studies depends on their reading skills. One of the strongest foundations in reading success includes alphabet knowledge. Nowadays, the utilization of information communication technology (ICT) influences young children’s learning and emergent literacy skills. Hence, this study explored the effectiveness of digital game-based learning resource in improving pupils’ alphabet knowledge specifically on vowels. An alphabet knowledge checklist on vowels was used to collect the data. One key finding from the study is that most of them have fair alphabet knowledge of vowels with an overall pre-test mean score of 17.91. Findings revealed that interactive learning resource was effective as reflected by a substantial increase of 8.95 points. The t-test for paired samples results in a t-value of -10.11 and a p-value of 0.000. Thus, the difference between the posttest and pretest is significant. Hence, digital game-based learning resource is an effective non-print instructional material in kindergarten for the improvement of alphabet knowledge on vowels. The study recommends the creation of contextualized digital game-based learning resource using consonants to further validate the result. A similar resource may also be suggested to other grade levels to confirm its effectiveness in improving alphabet knowledge.

Published: May 2023

The purpose of this research is to explore the effect of school closure during the economic and health crises on the learning loss of mathematics concepts of secondary students in public and private schools in Lebanon. This mixed research study used concurrent exploratory design involving quantitative data collection through teachers’ questionnaires and qualitative through a comparison of the official examinations in mathematics and CERD documents before and after the crisis. Data analysis was conducted along descriptive and inferential statistics for the questionnaire while document analysis was used to compare suspended concepts between 2019-2022 as well as a thorough analysis of the official exams for grade 12 – General Sciences. A parallel study following the same methodology was implemented for biology. The results showed that there is a significant learning loss in mathematics content along the three targeted years. The official national exams analysis grounded on Bloom’s taxonomy showed a decline in quality. Based on the teachers’ perspectives, there is a discrepancy between learning loss in private and public schools as well as between different regions. The results of this study will inspire the policymakers to implement plans for remedy and holistic measures for mathematics learning loss.

Authors: Yates Rebeca , Chitiyo George , Campbell-Gulley Britney
Published: May 2023

In the age of high stakes testing, the best instructional methods to promote academic achievement are frequently examined. The purpose of this study was to examine whether implementation of the Argument-Driven Inquiry (ADI) model in a high school chemistry course would be associated with improved student scores compared to a more traditional approach. The study employed a nonequivalent control group design to evaluate the posttest scores of students by instructional method and gender. Data were obtained from a sample of 28 honors students in a chemistry course in grades 10 and 11. The data consisted of pretest and posttest scores. A two-way analysis of covariance was used to address the study’s research questions, controlling for the students’ aptitude. The results showed that there were no significant differences in achievement between the ADI and traditional methods groups, controlling for the students’ aptitude. Also, the interaction between instructional method and gender was not significant. Use of ADI methods was, thus, found to neither improve nor be negatively associated with student performance.

Authors: Maunula Minna , Granlund Kati , Harju-Luukkainen Heidi
Published: May 2023

The diversity of pupils and their different difficulties challenge teachers' skills and methods in teaching. Some behavioral challenges require rapid intervention and a multidisciplinary and interdisciplinary approach from the teachers. An internationally recognized tool, TCM (Teacher Classroom Management), aims to support pupils' socio-emotional development, improve teacher-pupil interaction, and strengthen school-home cooperation. This pilot study examines teachers' experiences of TCM in Finnish primary school context. The study is qualitative, and the data (N=16) was collected through focus group interviews. According to the results, the teacher's strengthened group management skills were positively reflected in the classroom. Teachers´ positive communication with the class strengthened interaction and made it easier to deal with difficult issues. However, implementing TCM in the school community requires ongoing support. Collegial experiences and renewed group management skills strengthened the teachers' own experience of coping at work. The TCM method provided appropriate group management tools.

Published: May 2023

This study aims to investigate the effect of robotics design with Arduino on students' attitudes towards ICT courses and STEM. In this context, robotics design activities with Arduino were conducted with an experimental group, while the current IT curriculum was applied to a control group. The study lasted for a period of 12 weeks and was conducted with 53 middle school students. The Information Communication Technologies Course Attitude Scale (ICTCAS) and STEM Attitude Scale (SAS) were used as data collection tools. The study's findings revealed that robotics design activities with Arduino increased the students' attitudes towards engineering and technology in the context of STEM and ICT courses. Additionally, the participating students supported the use of robotics activities in their ICT course, and they reportedly found the activities to be fun, interesting, different, difficult, complex, and time-consuming. During the first weeks of the study, the students were excited, very curious, interested, enthusiastic, worried, and hesitant to participate in the activities and avoided them. However, in the subsequent weeks, they gained practical experience related to the activities and took on a more active role in the class.
Development of Soft Skills among Computing Students in Online Task-Based Learning: Insights from Technical Communication Course
Authors: AlGhamdi Rayed
Published: May 2023

Soft skills development, such as communication, teamwork, and problem-solving, is critical for computer students as they enter the profession. Students may be able to practice these skills in a virtual setting through an online task-based course. In this study, we investigated how successfully an online task-based course encouraged the development of soft skills among computing students. The course was designed to give students real-world challenges that required them to work in groups and communicate effectively with their classmates and instructors. The inquiry was based on a qualitative examination of the students' final reports. It gave data from two semesters (Fall 2020 and Spring 2021) of students who studied a course named Technical Communication. In total, 216 students' final reports were ready for investigation. A sample of 97 reports, representing 45%, was selected based on certain criteria to ensure a high-quality investigation. According to the findings of our study, the online task-based course helped boost the development of certain soft skills among students. Students noted an improvement in their ability to communicate effectively, cooperate successfully with team members, and identify professional responsibilities, as well as a rise in their self-confidence. Overall, this study emphasizes the necessity of introducing online task-based courses into computing students' curricula, giving them a valuable opportunity to develop critical soft skills. The present design of the Technical Communication Course is believed to be efficient regardless of the education delivery method (traditional/online).
Challenges Impacting Students’ Intention to Effectively Use E-Learning Method in a Virtual Learning Environment
Authors: Mokhtar Shaharina , Hilaluddin Thaharah , Nik Nazli Nik Nadian Niza
Published: May 2023

During the pandemic period, the education sector was heavily impacted involving transformations of instructional delivery from face-to-face to online mode. To date, we know that the virtual learning environment has been posing heavy demands particularly on the students. Learning from their own homes, they had to learn in isolation, deprived from the support of the instructor and peers as in conventional classrooms. As we continue to pursue online program offerings beyond the pandemic period, it is important to address students’ sense of isolation and their efforts to stay engaged in learning.  This study aims to identify the extent to which the challenges students faced in a virtual learning environment during the pandemic, have impacted their intention to effectively use the online learning method. Respondents for this study consist of students in one private university. This study employs a quantitative method. A set of questionnaire survey was administered online with a return of 367 respondents. The research data was analyzed using Structural Equation Modelling (SEM) and Smart PLS. The findings gathered indicate that self-regulation, students' sense of isolation and lack of learning resources significantly impact their intention to effectively use e-learning methods. It is thus evident that students’ intention to learn effectively must be supported by factors outside of themselves, to keep them highly motivated, disciplined, as well as proactive through self-directed learning.
