Published: March 2024

Rapid technological developments should support improving the quality of learning, one of which is online learning. . Online learning is carried out because learning in class is limited by space and time, thus limiting learning interactions. This study aims to describe and analyze student learning outcomes in mathematics by using video-assisted online interactive learning. Classroom Action Research (CAR) is used in this study with some stages namely preparation, action, observation, and reflection. The results of online learning using interactive videos are cycle I on student learning outcomes that obtain scores exceeding the minimum completeness score of 57% and are said to be complete. However, there are still 43% of students who obtain learning outcomes that are less than the minimum standard of completeness or have not been completed. The cause of this is the initial adaptation of students to using media that is packaged interactively. It was continued in the second cycle of learning to produce a learning completeness percentage of 86% for students who had exceeded the minimum standard of mastery scores. This shows an increase from cycle I to cycle II. In cycle II, the process of adaptation and the active participation of students began to have an impact on learning outcomes. Continuing in cycle III shows that the number of students who complete learning reaches 86%, the same as in cycle II, but there are still differences. Cycle II to Cycle III experienced an increase in the average value of learning outcomes, namely cycle II of 76.36; in cycle III, it increased to 78.79. These results indicate that online interactive learning using video can improve student mathematics learning outcomes.

Potential Benefits and Risks of Artificial Intelligence in Education
Authors: Özer Mahmut
Published: March 2024

Artificial Intelligence (AI) technologies are rapidly advancing and causing profound transformations in all aspects of life. In particular, the widespread adoption of generative AI systems like ChatGPT is taking this transformation to even more dramatic dimensions. In this context, the most comprehensive impact is observed in educational systems. Educational systems, on one hand, are faced with the urgent need to rapidly restructure education in response to skill changes in professions caused by the proliferation of such systems in the labor market. On the other hand, challenging questions arise about whether and to what extent these systems should be integrated into education, how they should be integrated if at all, and how ethical issues arising from AI systems can be addressed. This study evaluates the potential benefits and possible risks of using AI systems in educational systems from the perspectives of students, teachers, and education administrators. Therefore, the study discusses the potential uses of AI systems in education, as well as the risks they may pose. Policy recommendations are developed to maximize the benefits of AI systems while mitigating the ethical and other issues they may cause. Additionally, the study emphasizes the importance of increasing AI literacy for all education stakeholders. It suggests that raising awareness of both the benefits and ethical issues caused by AI systems can contribute to enhancing the benefits of these systems in education while minimizing their potential harms.
New reimbursement models to promote better patient outcomes and overall value in laboratory medicine and healthcare
Authors: Trenti Tommaso , Petrini Anna Maria , Plebani Mario
Published: March 2024

The most widespread healthcare reimbursement models, including diagnostic laboratory services, are Fee-for-Service, Reference Pricing and Diagnosis-Related Groups. Within these models healthcare providers are remunerated for each specific service or procedure they operate. Healthcare payers are increasingly exploring alternative models, such as bundled payments or value-based reimbursement to encourage value of patient care rather than the simple amount of delivered services. These alternative models are advised, as they are more efficient in promoting cost-effective, high-quality laboratory testing, thereby improving patient health outcomes. If outcomes-based evaluation is a pillar in a new vision of “Value-Based Healthcare”, an active policy of Value-Based Reimbursement in laboratory medicine will assure both an efficiency-based sustainability and a high-quality effectiveness-based diagnostic activity. This review aims to evaluate current and alternative reimbursement models, to support a wider agenda in encouraging more Value-Based Healthcare and Value-Based Reimbursement in laboratory medicine.

Published: March 2024

Plant-derived bioactive compounds displayed major therapeutic and chemo-preventive roles in the pathogenesis of numerous chronic malignancies such as cancer and enhanced oxidative stress and inflammation. Antioxidants found in food, such as genkwanin, may reduce oxidative stress and the release of cytokines or pathways that promote inflammation. The goal of this work is to summarize the potential for anticancer effects of genkwanin, a methoxyflavone that is present in a variety of plant species. This review examined and analyzed numerous research studies on identifying, isolating, measuring, and analyzing anticancer properties of genkwanin. The mechanisms involved cellular and molecular activities at various levels, including apoptosis induction and cancer cell growth and proliferation inhibition. Preclinical studies have demonstrated genkwanin’s effects and mechanism of action; however, further research is required to investigate its therapeutic potential thoroughly. Additional research is needed to further our understanding of the pharmacodynamic effects of genkwanin. Additional toxicological study is necessary to evaluate the clinical efficacy and safety of genkwanin, which would help scientists to elucidate a potent drug candidate for cancer management.

Published: March 2024

Adequate financial decision-making necessitates a solid foundation in financial literacy and comprehension of its principles. This is particularly crucial for students, as their financial and behavioral choices can significantly impact their future financial and career prospects. Consequently, the present study aimed to explore the causal links between economics education, financial literacy, decision-making abilities, and entrepreneurial intentions. Employing a descriptive-correlational approach, the researchers utilized structural equation modeling, drawing on a sample of 375 individuals purposefully selected from a population of 11,345 students at Urmia University. Data were collected through a questionnaire, and the research variables were initially assessed using multiple correspondence analysis. Subsequently, the research model was estimated. The findings revealed a positive and substantial impact of economics education on students' financial literacy and the influence of economics education on decision-making skills and entrepreneurial intentions through the mediating factor of financial literacy. Furthermore, the results confirmed the moderating role of socioeconomic status in the relationship between economics education and financial literacy. Consequently, the study's outcomes can inform educational institutions and policymakers, supporting the implementation of policies aimed at enhancing general economic education and emphasizing the equitable and distributive nature of such initiatives.
The Feathered Man: The Reception of Daniel 4 in a 17th-Century English Tapestry of Nebuchadnezzar Transformed into a Beast
Authors: Atkins Peter Joshua
Published: March 2024

The imagery of Nebuchadnezzar’s divine affliction in Daniel 4 is as complex as it is fantastic. A variety of literary images interweave to present the king’s affliction in explicitly animalising terms. Despite this complexity, most visual depictions of the text focus on a largely similar image – that of Nebuchadnezzar eating grass or living naked in the wild. However, in a 17th-century English tapestry series associated with Thomas Poyntz, an altogether different scene is envisioned. Nebuchadnezzar is portrayed as fully clothed in the city of Babylon and, even more intriguingly, is explicitly depicted with both birds’ claws and feathers. This paper outlines trends in visually depicting Nebuchadnezzar’s affliction in art and then examines the tapestry’s visual portrayal of Daniel 4. In so doing, it is observed how the tapestry is distinctive in representing both the divine pronouncement and seeming enactment of this affliction in one image, as well as discerning the influence of lycanthropic interpretations of Daniel 4. Finally, this paper returns to read the biblical narrative in light of this unusual visual representation and observes how it draws the reader’s attention to two often overlooked textual features: the absence of other characters within this specific scene, and the rapidity with which Nebuchadnezzar’s affliction commences.

Published: March 2024

Camouflage is a common technique in nature, enabling organisms to protect themselves from predators. The development of novel camouflage technologies, not only in fundamental science, but also in the fields of military and civilian applications, is of great significance. In this study, we propose a new type of deep-subwavelength four-layered meta-coating consisting of Si, Bi, Si, and Cr from top to bottom with total thickness of only ∼355 nm for visible-infrared compatible camouflage. The visible color and the infrared emission properties of the meta-coating can be independently adjusted. Colorful meta-coating for visible camouflage can be obtained by changing the thickness of top Si layer, while the selective high emissivity in non-atmospheric window for infrared camouflage remains. Due to the deep-subwavelength properties, the meta-coating shows high angle tolerance in both visible and infrared regions. The compatible camouflage capability of our proposed meta-coating in the visible-infrared region is validated under different environments. The deep-subwavelength, angular insensitivity, visible-infrared compatibility and large-area fabrication feasibility promise the meta-coating an effective solution for camouflage in various applications such as military weapons and anti-counterfeiting.

Published: March 2024

The advancement in material platforms exhibiting strong and robust electro-optic effects is crucial for further progress in developing highly efficient and miniaturized optoelectronic components with low power consumption for modern optical communication systems. In this work, we investigate thin-film lead zirconate titanate (PZT) substrates grown by a chemical solution deposition technique as a potential platform for on-chip plasmonic electro-optic modulators. A high modulation depth (>40 %) is achieved with 15 μm-long electro-optic directional coupler modulators. An unusual cutoff in the modulation frequency response at ∼200 kHz is observed and further studied with respect to possible reorientation effects. Second-harmonic generation signals are found influenced by the externally applied electric field, indicating that the domain reorientation effect can be responsible for the unusual frequency response observed.

Objectives

To assess the feasibility of methods and estimate the potential effect of interrupting sedentary behaviour, with intermittent or continuous physical activity breaks, on cognitive performance in young people with Cerebral Palsy.

Methods

A randomised three-arm exposure response cross-over design with process evaluation. Participants were recruited throughout the Thames Valley, UK between 01/11/2018 to 31/03/2020. The three 2 h activity exposure visits included: (i) sitting only (controls), (ii) sitting plus 20 min of moderate-to-vigorous activity burst, or (iii) 4×5 min of moderate-to-vigorous activity bursts, during a 2.5 h sedentary session. Measures of feasibility were sought. Cognitive performance outcomes (using the Eriksen Flanker task and Forward and Backward Digit Span) were delivered before and after the 2 h testing period.

Results

36 participants were randomised (age 13.2±2.7, Gross-Motor Functional Classification System 1–3). Study retention was 83 % across all three interventions and overall missing data for measures was 4 %. A small intervention effect was found in reaction time in the 4×5 min physical activity exposure session compared to the sedentary control condition (0.42; 95 % CI 0.40 to 0.79). There were two research-related minor adverse effects, an allergic reaction to the FreeStyle Libre and feeling faint and vomiting after consumption of glucose solution. Both events were resolved and participants continued with the study.

Conclusions

The study design and intervention implementing short bursts of physical activity was feasible and indicated a potential effect on reaction time as a measure of cognitive performance in young people with cerebral palsy.

Forebrain EAAT3 Overexpression Increases Susceptibility to Amphetamine-Induced Repetitive Behaviors

Published: March 2024

Obsessive-compulsive disorder (OCD) is a debilitating psychiatric disorder characterized by intrusive obsessive thoughts and compulsive behaviors. Multiple studies have shown the association of polymorphisms in theSLC1A1gene with OCD. The most common of these OCD-associated polymorphisms increases the expression of the encoded protein, excitatory amino acid transporter 3 (EAAT3), a neuronal glutamate transporter. Previous work has shown that increased EAAT3 expression results in OCD-relevant behavioral phenotypes in rodent models. In this study, we created a novel mouse model with targeted, reversible overexpression ofSlc1a1in forebrain neurons. The mice do not have a baseline difference in repetitive behavior but show increased hyperlocomotion following a low dose of amphetamine (3 mg/kg) and increased stereotypy following a high dose of amphetamine (8 mg/kg). We next characterized the effect of amphetamine on striatal cFos response and found that amphetamine increased cFos throughout the striatum in both control andSlc1a1-overexpressing (OE) mice, butSlc1a1-OE mice had increased cFos expression in the ventral striatum relative to controls. We used an unbiased machine classifier to robustly characterize the behavioral response to different doses of amphetamine and found a unique response to amphetamine inSlc1a1-OE mice, relative to controls. Lastly, we found that the differences in striatal cFos expression inSlc1a1-OE mice were driven by cFos expression specifically in D1 neurons, asSlc1a1-OE mice had increased cFos in D1 ventral medial striatal neurons, implicating this region in the exaggerated behavioral response to amphetamine inSlc1a1-OE mice.
Value estimation versus effort mobilization: a general dissociation between ventromedial and dorsomedial prefrontal cortex
Authors: Clairis Nicolas , Pessiglione Mathias
Published: March 2024

Deciding for a course of action requires both an accurate estimation of option values and a right amount of effort invested in deliberation to reach sufficient confidence in the final choice. In a previous study, we have provided evidence, across a series of judgement and choice tasks, for a dissociation between the ventromedial prefrontal cortex (vmPFC), which would represent option values, and the dorsomedial prefrontal cortex (dmPFC), which would represent the duration of deliberation. Here, we first replicate this dissociation and extend it to the case of an instrumental learning task, in which 24 human volunteers (13 women) choose between options associated with probabilistic gains and losses. According to fMRI data recorded during decision-making, vmPFC activity reflects the sum of option values generated by a reinforcement learning model, and dmPFC activity the deliberation time. To further generalize the role of the dmPFC in mobilizing effort, we then analyze fMRI data recorded in the same participants while they prepare to perform motor and cognitive tasks (squeezing a handgrip or making numerical comparisons) to maximize gains or minimize losses. In both cases, dmPFC activity is associated with the output of an effort regulation model, and not with response time. Taken together, these results strengthen a general theory of behavioral control that implicates the vmPFC in the estimation of option values and the dmPFC in the energization of relevant motor and cognitive processes.

Significance statementThe medial prefrontal cortex (mPFC) is known to represent key variables needed for choosing a course of action. We previously suggested a functional partition of this brain region: the expected values of choice options are signaled by the ventral part (vmPFC) and the effort invested in decision-making by the dorsal part (dmPFC). Here, we generalize this functional partition to various motor and cognitive tasks, using fMRI in healthy volunteers. Results show that vmPFC activity reflects the expected value of options generated by a reinforcement learning model (whether the goal is to maximize reward or avoid punishment), while dmPFC activity reflects the output of an effort regulation model (whether the task is to produce force or to compare digits).

Evolving sets of keyphrases (and keywords) observed in representative jour­nals carry all needed information about this development. A model for the growth of thesauri as well as asymptotic properties and estimators for the parameters are proposed in [1]. The results of experimental analysis enable these properties and estimators to be used for practical calculations.The analysis suggests that sufficient accuracy of approximations is achieved quite fast – for sequences of few hundred length.Statistical analysis of ``Discrete Mathematics'' journal keyphrases database illustrate the use and the reliability of estimations.

On the stability of one characterization of the stable distributions
Authors: Yanushkevichiene Olga , Yanushkevichius Romanas
Published: March 2024

As early as 1923, Georg P6lya wrote: ``The Gaussian error law possesses the property that it remains valid under a linear combination of errors. The Gaussian error law can be characterized by this property to some extent – it is the only law that admits steadiness with respect to linear combinations of errors''. The idea of using linear combinations of random variables to cha­racterize the stable distributions has been extended by P. Levy. We investigate the stability of this characterization.
Estudio biográfico narrativo sobre las creencias de estudiantes de pedagogía y la construcción de su identidad docente
Authors: Sanhueza Mansilla Claudio , Estay Rojas Ingrid , Herrera González Valentina
Published: March 2024

Diversas investigaciones han profundizado en la relación entre las representaciones y epistemologías personales que tienen los docentes con su desempeño y desarrollo profesional, así como el débil impacto que tiene la formación inicial en su sofisticación o transformación duradera. En este escenario, el presente estudio es una investigación cualitativa cuyo objetivo es conocer las creencias sobre la enseñanza y el aprendizaje que tienen estudiantes de primer año de pedagogía. La técnica de recolección de datos se basó en narraciones autobiográficas y entrevistas a estudiantes de las carreras de Pedagogía Básica, Inglés y Educación Parvularia de una Universidad privada de Santiago de Chile. Posteriormente, se realizó un análisis, a partir de un enfoque biográfico-narrativo, de sus trayectorias pre-formativas, develando el desarrollo situado de creencias existentes ya en el primer año de ingreso a los programas de formación pedagógica. Los resultados muestran una influencia directa de la trayectoria escolar sobre la formación de creencias y la configuración de su identidad docente. A partir de ello se propone fortalecer la narración y análisis de estas experiencias previas como una estrategia de conocimiento y modificación de creencias en la formación inicial.
Characterization of self-reported sleep quality in male and female trained amateur triathletes: a descriptive study
Authors: Da Silva Neto Luiz Vieira , Albuquerque Melo Kramer Tatiana , Alves Trajano Gloria Maria , Frota Solon Júnior Luiz José
Published: March 2024

Sleep quality is a determining factor for the performance and health of athletes in general. The aim of the present study was to characterize the sleep quality in male and female trained amateur triathletes aged 20 to 59 years. A survey was conducted with 151 trained amateur triathletes, 108 male (38.6 ±8.1 years, triathlon training experience 5.8 ±4.3years, training frequency 6.3 ±0.9 days per week) and 43 female (39.3 ±7.6 years, triathlon training experience 4.8 ±3.3years, training frequency 6.5 ±0.6 days per week). The sleep quality was measured using the Pittsburgh Sleep Quality Index-Br (PSQI-Br), total values below 05 points indicate good sleepers, and values equal to or greater than 05 points indicate poor sleepers. Data from the subscales were analyzed using absolute and relative frequency. The other data in order to characterize sleep quality were analyzed with median, mean, standard deviation, standard error, and 95% Confidence Interval of mean.  Male and female triathletes have poor sleep quality (values equal or greater than 05 points), that can have negative effects on health and performance.  In conclusion, all triathletes regardless of gender and age group have poor sleep quality.
Everyday Meals in Regency London
Authors: Brears Peter
Published: March 2024

This is a continuation of the author's study of a Regency family's (the Feltuss family) culinary habits. This essay examines how they catered for special occasions, from entertaining family and relations, to the meals served to celebrate calendar customs or rites of passage. It is revealing to read what a real family chose to eat at these events, rather than rely on the usual literary and other more general sources of information.
Feeding Harvesters in the Mid-Eighteenth Century
Authors: Thick Malcolm
Published: March 2024

Little has been written by historians on food provided for harvest workers in England. Christopher Dyer, in 1988, used medieval manorial records to examine changes in diet in the late Middle Ages but he did so in terms of food acquired by manors to feed workers, not the actual meals they consumed. E.J.T. Collins in 1976 examined migrant labour in British agriculture in the nineteenth century but was not concerned with food consumed. David Hoseason’s book on the nineteenth century agricultural worker has little in it on harvest food. Other writers of food history have simply used information extracted and summarized from William Ellis (as I did in my introduction to 2000 edition of Ellis’s The Country Housewife’s Family Companion of 1750). Ellis stands out as the only writer, in the eighteenth or almost any other century, who tells us what exactly harvesters were fed, on a meal by meal basis and how he, and his Hertfordshire farmer neighbours (or rather their wives), conducted this victualling. This paper will examine closely what he had to say on the subject and seek corroboration from other sources of Ellis’s information on harvest food.
Exeter’s Elizabethan Bakers
Authors: Osborne Kate
Published: March 2024

This article arises from a prosopographical study of Exeter’s sixteenth-century ‘ordinary’ population, about whom far less is known than those who were part of the city’s trading and political elite. Prosopographical study requires that a large quantity of individual mentions of personal names, and the actions attached to them, from across a wide range of documents are entered into a database and then searches made on individuals’ names to create biographies. While this article concentrates on bakers, until similar studies are undertaken on other occupations, it is difficult to say what, apart from bread, differentiates the baking trade from other trades in Elizabethan Exeter. For the time being, however, this article sketches some of the aspects of bakers’ lives over 400 years ago, discerned from organizing snippets of information about individuals pursuing that trade.

Thermodynamic relationships between time, capital, and labour
Authors: Dobija Mieczysław , Renkas Jurij
Published: March 2024

In the theoretical achievements of economics, the past has left many insinuations, not always accurate terms and also controversies. This does not burden the scholars whose diligent efforts fell on the immature ground of general knowledge, in particular the lack of thermodynamics. The categories of capital, profit, labour are basic examples. There was also a lack of understanding of the nature of time. This issue was as if left to physicists, despite the fact that the use of present and future value was and is a significant achievement in economics and accounting. On the other hand, among those engaged in physics, there are divergences about time travel. The great idea of the economy as a game with nature with a non-zero positive sum has also not spread in economic theory, reinforcing the aspiration to belong to the natural sciences. Therefore, we take up the consideration of the capital-labour-time triad as an important basic element of economic knowledge. In our view, this correctly understood triad will correctly illuminate many economic issues and can form the hard core of a scientific program for improving economic and accounting theory. Thus, the epistemology of I. Lakatos defines the methodology of ongoing research, in which positive heuristics and empirical verification are the engine of scientific action.

Социально-экономические риски стигматизации ВИЧ-инфицированных на примере студенческой молодёжи
Authors: Коршунова Юлия Александровна
Published: March 2024

В данной статье рассматривается феномен стигматизации людей, живущих с ВИЧ, и его социально-экономические риски на примере студенческой молодёжи. Автором были проведены глубинные интервью среди студентов медицинских и не медицинских российских вузов и полуформализованный экспертный опрос. В результате глубинных интервью были выявлены стигматизирующие установки у студенческой молодёжи по отношению к людям с ВИЧ-позитивным статусом, а также проанализирована информированность студентов в области заболевания. В исследовательской работе проведено сравнение студентов медицинских и не медицинских направлений обучения. По итогам экспертного опроса была оценена эффективность мер по борьбе со стигматизацией ВИЧ в России: информирование населения по вопросам ВИЧ органами здравоохранения, средствами массовой информации; информирование детей в школах; проведение различных научных исследований по вопросам ВИЧ; международное сотрудничество и обмен информацией в рамках борьбы с ВИЧ; защита людей с ВИЧ от дискриминации на законодательном уровне. Эксперты оценили необходимость внедрения дополнительных мер, реализуемых в зарубежных странах. Были разработаны практические рекомендации по снижению социально-экономических рисков от стигматизации ВИЧ-инфицированных для Министерства просвещения, Министерства здравоохранения, Федерального собрания.
