Published: December 2021

Introduction: As significant autonomy is given in a Massive Open Online Course (MOOC), online self-regulated learning (SRL) ability is crucial in such courses. We aim to measure the online SRL abilities of early-career medical doctors enrolled in a MOOC. Methods: We performed a cross-sectional study using the Self-Regulated Online Learning Questionnaire-revised version (SOL-Qr). We conducted a three-stage cross-cultural validation of the SOL-Qr, followed by Confirmatory Factor Analysis (CFA). The online SRL ability of 5,432 medical doctors enrolled in a MOOC was measured using the validated SOL-Qr. Results: The CFA of the cross-translated SOL-Qr confirmed its comparability to the original version, with excellent validity & reliability. Participants showed high levels of online SRL during their early careers. Despite high online SRL scores, MOOC completion rate was low. Male participants showed slightly better time management ability than female participants. Participants working in the primary epicentrum for COVID-19 in the country showed lower online SRL scores, while participants who graduated from higher accreditation levels showed better time management ability. Conclusion: The SOL-Qr and its subscales are suitable and valid for measuring the online SRL abilities of medical doctors in a MOOC during their early-career period. Time management ability was associated with previous experience during the medical education period, while other online SRL subscales were mostly associated with workload. However, as the scores did not correlate with the time spent for learning in MOOC, the corresponding learning effort or time spent may be beyond just the commitment to the described MOOC.

"Struggling Right Along With You": Precarity and the Power of Medical Crowdfunding Campaign Narratives
Authors: Paust Sarah
Published: December 2021

Medical fundraisers—which feature patients or caregivers seeking funds for medical care, procedures, or other needs—are ubiquitous on social media, and US-based GoFundMe.com is one of the most popular platforms. The rise of platforms like GoFundMe as forms of medical care and triage is notoriously intertwined with the failures of the U.S. healthcare system. Medical crowdfunding campaigns in the U.S. span diverse topics, invoke a wide range of moral discourses, and are affected deeply by race, gender, class, religion, and (dis)ability. Drawing on insights from a discourse analysis of ten “trending” campaigns hosted on GoFundMe in 2019, I argue that campaigns are participatory narratives (because organizers, beneficiaries, and donors can interact within the campaign space) that rely upon an individualizing discourse of deservingness to create reciprocal ties within biosocial communities of care. As politico-moral projects, medical crowdfunding campaigns are at once reflective of and responsive to normalized precarity. Crowdfunding narratives are spaces in which idealized neoliberal citizen-subjects are produced and valorized collaboratively through the discursive work of campaign organizers and donors, limiting (and enabling) our imaginaries of community and care.

One of the major constraints to production of okra (Abelmoschus esculentus L.) in Nigeria and in particular in Kaduna and Zamfara States, is the problem of okra mosaic virus and okra leaf curl virus. This study was carried out to provide information on the occurrence and distribution of okra mosaic and okra leaf curl viruses on okra, in Kaduna and Zamfara states, Nigeria. A survey of okra-producing farms was carried out during dry and wet seasons of 2017 cropping season in Kaduna (Zaria, Lere, and Igabi Local Government Areas) and Zamfara (Gusau, Bungudu, and Zurmi LGAs) states. Leaf samples (15) of symptomatic okra plants were collected from each farm in the study area. The total number of plants and the number of symptomatic plants within each subplot were recorded, and the disease incidence was determined. Double Antibody Sandwich Enzyme-Linked Immunosorbent Assay (DAS- ELISA) kit was used in the detection of Okra Mosaic Virus while Polymerase Chain Reaction (PCR) was employed for the detection Okra Leaf Curl Virus. The results showed that all the okra leaf samples tested for OLCV were negative in this study while OkMV was tested positve in all the samples with a recorded incidence of  20 % and 14 %  in Kaduna and Zamfara states respectively, however, only 8 out of total weed samples were also tested positive for OKV, but all were tested negative to OLCV.

An approach to the design of mathematical task sequences: Conceptual learning as abstraction

Authors: Simon Martin A.
Published: December 2021

This paper describes an emerging approach to the design of task sequences and the theory that undergirds it. The approach aims at promoting particular mathematical concepts, understood as the result of reflective abstraction. Central to this approach is the identification of available student activities from which students can abstract the intended ideas. The approach differs from approaches in which learning to solve the problem posed is the intended learning. The paper illustrates the approach through data from a teaching experiment on division of fractions. Una aproximación al diseño de secuencias de tareas matemáticas: aprendizaje conceptual como abstracción Este artículo describe una aproximación emergente al diseño de secuencias de tareas y la teoría que la sustenta. La aproximación pretende promover conceptos matemáticos concretos como resultado de una abstracción reflexiva. Es central en esta aproximación la identificación de actividades disponibles para los estudiantes con las que puedan abstraer las ideas pretendidas. La aproximación difiere de aquellas en las que el aprendizaje para resolver problemas es el aprendizaje que se pretende. El artículo ilustra la aproximación a través de datos de un experimento de enseñanza sobre la división de fracciones.Handle: http://hdl.handle.net/10481/41628WOS-ESCI

Multimodality and the Semiotic Bundle Lens: A Constructive Resonance with the Theory of Objectification
Authors: Sabena Cristina
Published: December 2021

The paper situates mathematics teaching-learning processes within a multimodal perspective and discusses a semiotic approach apt to seize this dimension, namely the Semiotic Bundle lens. This analytical tool considers the great variety of semiotic resources through which mathematical meanings emerge and evolve in the classroom, ranging from embodied ones such as gestures, to symbolic systems. In particular, the analysis considers them in a systemic and dynamic way. The theoretical account is illustrated by means of an example on children spatial conceptualization, carried out in kindergarten. The data analysis will constitute a background against which the connections with the Theory of Objectification will be highlighted, showing a constructive resonance between the two theories.La multimodalidad y el lente Semiotic Bundle: una resonancia constructiva con la teoría de la objetividadEl artículo sitúa los procesos de enseñanza-aprendizaje de las matemáticas dentro de una perspectiva multimodal y discute un enfoque semiótico apto para aprovechar esta dimensión llamada el lente Semiotic Bundle. Esta herramienta analítica tiene en cuenta la gran variedad de recursos semióticos a través de los cuales los significados matemáticos emergen y evolucionan en el aula, como los gestos hasta los sistemas simbólicos. En particular, el análisis los considera de forma sistémica y dinámica. La explicación teórica se ilustra mediante un ejemplo de conceptualización espacial de niños, llevado a cabo en el jardín de infantes. El análisis de datos constituirá un trasfondo contra el cual se resaltarán las conexiones con la teoría de la objetivación, mostrando una resonancia constructiva entre las dos teorías.Handle: http://hdl.handle.net/10481/53006Doi: 10.30827/pna.v12i4.7848Scopus record and citations

Authors: Cornejo-Morales Claudia Elizabeth , Goizueta Manuel , Alsina Ángel
Published: December 2021

Se presenta un modelo, denominado Situación Argumentativa (SA), para analizar y caracterizar la argumentación en la Educación Matemática Infantil. Desde un enfoque integrador que considera aspectos contextuales y funcionales de la argumentación, la SA considera cinco componentes: argumento (¿qué se argumenta? y ¿por qué?); interacción (¿quiénes argumentan?); función de la argumentación (¿para qué se argumenta?); carácter de la argumentación (¿cómo se argumenta?); y matemática (¿sobre qué se argumenta?). Para ejemplificar el uso de la SA y dar cuenta de sus alcances y limitaciones, presentamos el análisis de tres episodios de clase. Finalizamos discutiendo las proyecciones del modelo para las matemáticas de las primeras edades

Generalization in chess thinking

Authors: D'Eredità Giuliano , Ferro Mario
Published: December 2021

In this work we deal with generalization in chess thinking. Generalization is a complex process based on information people acquired during previous experiences. In the field of chess, chess books, chess education and personal game practice supply the information for generalization to occur. The way in which generalization is performed in chess is still a topic that deserves more research. In this article we dwell on early theories about chess thinking. We underline the role played by what we call configural concepts, in which geometrical patterns and logical expected developments coexist. We suggest that the idea of configural concepts, along with generalization and abduction constitute the basis of chess thinking.Generalización en el pensamiento al jugar ajedrezEn este trabajo abordamos la generalización en el pensamiento en el juego del ajedrez. La generalización es un complejo proceso basado en información adquirida durante experiencias previas. En el campo del ajedrez, los libros de ajedrez, la educación en el ajedrez y la práctica personal con el juego aportan la información que posibilita la generalización. La forma en que la generalización se produce en el ajedrez es todavía un tema que merece más investigación. En este artículo consideramos teorías tempranas sobre el pensamiento en el ajedrez. Subrayamos el papel que juegan lo que llamamos conceptos configurales, en los cuales coexisten los patrones geométricos y desarrollos lógicos esperados.

Introduction: The phenomenological, epistemological, and semiotic components of generalization

Authors: Radford Luis
Published: December 2021

In the first part of this article, I argue that generalization involves three related components: phenomenological, epistemological, and semiotic. I also argue that the concept of generalization conveyed by theories of knowing (e.g., rationalist and empiricist) depends on the manner in which these theories understand the above three components and their interrelations. I elaborate my argument in reference to a cultural-historical dialectical concept of generalization. In the second part of the article, I provide an overview of the articles contained in this special issue and discuss their contributions to educational research.Los componentes fenomenológico, epistemológico y semiótico de la generalizaciónEn la primera parte de este artículo, sostengo que la generalización incluye tres componentes entrelazados: un componente fenomenológico, un componente epistemológico y un componente semiótico. También sostengo que el concepto de generalización que presentan las teorías del conocimiento (por ejemplo, teorías racionalistas y empiristas) depende de la manera en que esas teorías conciben los tres componentes anteriores y sus interrelaciones. Mi argumento es elaborado a partir de un concepto cultural histórico dialéctico de generalización.

Важным элементом современных агрономических технологий в растениеводстве является применение биопрепаратов. В России сейчас производят десятки наименований биопрепаратов, но далеко не все они обладают заявленной эффективностью. Изучено влияние биопрепарата нового поколения «Биогерц» на урожайность и качество зерна сельскохозяйственных культур (озимая пшеница, кукуруза, подсолнечник, горох) с учетом почвенно-климатических условий Кабардино-Балкарии. Определены энергии прорастания и всхожесть семян культур при различных концентрациях препарата (3, 5 и 10 %). На всех испытанных культурах применение препарата оказывало положительное влияние, и с увеличением его концентрации эффективность действия усиливалась.

Посевные качества семян являются одной из ведущих составляющих получения высоких урожаев. В процессе воспроизводства, при нарушении технологических процессов возделывания, а в большей степени при уборке, транспортировке и послеуборочной доработки семян, в результате механического засорения происходит постепенное ухудшение посевных качеств. Соблюдение требований нормативно-технической документации (НТД) в области семеноводства является залогом получения хороших урожаев семян с показателями качества, отвечающими этим требованиям. Проанализированы данные по посевным показателям семенного материала за 2010 – 2015 гг. исследований, что позволило выявить общую массу некондиционных партий и отразить наиболее яркие моменты несоответствий требованиям НТД в области семеноводства по показателю «Чистота семян», так как именно на этот показатель приходится самая большая доля всех выявленных несоответствий. Подобный вид мониторинга дает право органу исполнительной власти — Россельхознадзору — не допускать нарушений в области семеноводства.
Influence of Ancient Mesopotamian Aesthetics of Gardens/Parks and Water Installations on the Development of Landscape Architecture
Authors: Stančius Antanas , Grecevičius Petras

Based on the information from fundamental historical sources, the oldest origins of civilization can be found in the river valleys of the Tigris and the Euphrates. Throughout Mesopotamia important routes of trade and migration of peoples followed, which influenced the emergence and development of one of the world’s first urban-type civilizations. It was here that the Sumerian civilization evolved, leading to a major cultural and technological breakthrough. Their widely used irrigation canals influenced not only the landscape, but also the entire ecological, economic and political systems of the time, water being a particularly important factor in this civilization. The oldest known gardens have also expanded here, and the Hanging Gardens of Babylon still fuel people's imagination. Due to its unique geographical location, the region has had a profound impact on the surrounding nations, and it is no accident that the Assyrian Imperial Parks of Northern Mesopotamia exerted a great influence on the civilizations that followed. Undoubtedly, ancient Mesopotamia occupies a fundamental place in the development of garden art. With the growing use of roof gardens and the use of plants in modern architectural constructions as an extremely important tool for composition, it is worth exploring more closely the origins of this landscape-relevant process.
Google Trends as a Method to Predict New COVID-19 Cases and Socio-Psychological Consequences of the Pandemic

Understanding how people react to the COVID-19 crisis, and what the consequences are of the COVID-19 pandemic is key to enable public health and other agencies to develop optimal intervention strategies. Because the timely identification of new cases of infection has proven to be the key to timely respond to the spread of infection within a particular region, we have developed a method that can detect and predict the emergence of new cases of COVID-19 at an early stage. Further, this method can give useful insights into a family’s life during the pandemic and give the prediction of birth rates. The basic methodological concept of our approach is to monitor the digital trace of language searches with the Google Trends analytical tool (GT). We divided the keyword frequency for selected words giving us a search frequency index and then compared searches with official statistics to prove the significations of results. 1) Google Trends tools are suitable for predicting the emergence of new COVID-19 cases in Croatia. The data collected by this method correlate with official data. In Croatia search activities using GT for terms such as “PCR +COVID”, and symptoms “cough + corona”, “pneumonia + corona”; “muscle pain + corona” correlate strongly with officially reported cases of the disease. 2) The method also shows effects on family life, increase in stress, and domestic violence. 3) Birth rate in 2021 will be just 87% of what it would be “a normal year” in Croatia. 4) This tool can give useful insights into domestic violence. Unquestionably, there are still significant open methodological issues and the questionable integrity of the data obtained using this source. The fact is also a problem that GT does not provide data on which population was sampled or how it was structured. Although these open-ended issues pose serious challenges for making clear estimates, statistics offer a range of tools available to deal with imperfect data as well as to develop controls that take data quality into account. All these insights show that GT has the potential to capture attitudes in the broad spectrum of family life themes. The benefit of this method is reliable estimates that can enable public health officials to prepare and better respond to the possible return of a pandemic in certain parts of the country and the need for responses to protect family well-being.
