Dental undergraduate students’ perspectives of online assessments conducted during the Covid-19 pandemic – a report from one South African university

IntroductionOnline assessments are commonly used in health sciences curricula worldwide. However, it is unclear on how undergraduate dental therapy and oral hygiene students at a South African university responded to the transition from traditional classroom-based to online assessments, as a result of the Covid-19 pandemic. Aims and objectivesThis paper reports on students’ knowledge and practices of,attitudes towards and preparedness for online assessments.MethodThis was a descriptive study, using a mixed methodsapproach to obtain quantitative and qualitative data through an online questionnaire.ResultsThis study indicated most students (n=93, 87%) were familiar with online assessments; however, only (n=68, 63.5%) were confident about taking these tests. Most students agreed that online assessment helped them grasp all aspects of theory, while less than half of third-year students agreed that online assessments helped them to integrate theory into clinical practice. The reported challenges were connectivity problems with online assessment and insufficient time to complete online tests. ConclusionThis study demonstrated that undergraduate dental students were familiar with online assessments and were confident about taking them. They believed this helped them grasp all aspects of theory despite specific challenges associated with the use of online assessments. This study suggests that online assessments could be a valuable method in measuring student com

What kind of a problem is loneliness? Representations of connectedness and participation from a study of telepresence technologies in the UK.

Loneliness is represented in UK policy as a public health problem with consequences in terms of individual suffering, population burden and service use. However, loneliness is historically and culturally produced; manifestations of loneliness and social isolation also require social and cultural analysis. We explored meanings of loneliness and social isolation in the UK 2020-2022 and considered what the solutions of telepresence technologies reveal about the problems they are used to address. Through qualitative methods we traced the introduction and use of two telepresence technologies and representations of these, and other technologies, in policy and UK media. Our dataset comprises interviews, fieldnotes, policy documents, grey literature and newspaper articles. We found loneliness was represented as a problem of individual human connection and of collective participation in social life, with technology understood as having the potential to enhance and inhibit connections and participation. Technologically-mediated connections were frequently perceived as inferior to in-person contact, particularly in light of the enforced social isolation of the COVID-19 pandemic. We argue that addressing loneliness requires attending to other, related, health and social problems and introducing technological solutions requires integration into the complex social and organisational dynamics that shape technology adoption. We conclude that loneliness is primarily understood as a painful lack of co-presence, no longer regarded as simply a subjective experience, but as a social and policy problem demanding resolution.

Elementary School Teachers’ Insight to Rotation Models of Blended Learning

Blended learning, which is mostly used in higher education, is introduced to Elementary Schools teachers through teaching and learning English. This study aimed at exploring the teachers’ responses on their attitudes towards the implementation of blended learning as an interactional teaching and learning tool in English course. Observation, questionnaire, and interview were given to 24 elementary school teachers who are also students of English in Open University. The result showed around 45.8% of them have already had PC or laptop and only 8.2% really have problem in internet connection. Further, 50% of teachers stated that rotation blended learning is ease their teaching and learning.

Beginning science teachers’ online classes: A narrative inquiry

With the unprecedented shift to online or flexible learning modes, both teachers and students adapt to the new normal of education. A qualitative study aimed to draw out the voices of three beginning science teachers, the study utilized the narrative inquiry approach through in-depth interviews. It was found that beginning science teachers are faced with challenges: transitioning to the actual teaching practice and adjusting to the new normal in education. Beginning science teachers voiced out their challenges, including adapting to the culture of the new generation of students, access to a stable internet connection, problems with technology use, and teaching-learning process adjustments. Coping strategies include creative and responsive adjustments to teaching-learning, assessment of learning, learning mode, and internet connection problems and online platforms. Their stories serve as a springboard for interventions that guide and assist beginning teachers.

The effect of web-based peer feedback on students’ writing achievement

Peer feedback via CMC modalities has become an alternative to conventional in-class peer feedback due to the rapid rise of educational technology and the widespread use of computer-mediated communication in L2 education. Despite the fact that much research has been published on the benefits of CMC tools for enhancing L2 proficiency, the number of studies on peer feedback provided on online platforms and its effect on L2 writing achievement is limited. Therefore, the current research, with the participation of 42 university preparatory class engineering students, aimed to investigate the effectiveness of web-based peer feedback on L2 writing achievement and their views towards web-based peer feedback. For this study, the purposive sampling method was employed. To collect the data, pre-and post-tests were used and semi-structured interviews were conducted with the experimental group members. The findings have indicated that compared to traditional teacher feedback, web-based peer feedback is found to be more effective in improving students’ L2 writing achievement. Regarding the views of participants, web-based platforms to give feedback has several advantages, including practicality, ease of access, motivation, and continuous learning. The quality of the input, a lack of technological resources, or connectivity problems were regarded as the disadvantages.

Asymptotics of multivariate sequences in the presence of a lacuna

We explain a discontinuous drop in the exponential growth rate for certain multivariate generating functions at a critical parameter value in even dimensions d \geq 4 . This result depends on computations in the homology of the algebraic variety where the generating function has a pole. These computations are similar to, and inspired by, a thread of research in applications of complex algebraic geometry to hyperbolic PDEs, going back to Leray, Petrowski, Atiyah, Bott and Gårding. As a consequence, we give a topological explanation for certain asymptotic phenomena appearing in the combinatorics and number theory literature. Furthermore, we show how to combine topological methods with symbolic algebraic computation to determine explicitly the dominant asymptotics for such multivariate generating functions, giving a significant new tool to attack the so-called connection problem for asymptotics of P-recursive sequences. This in turn enables the rigorous determination of integer coefficients in the Morse–Smale complex, which are difficult to determine using direct geometric methods.

An Efficient Algorithm for All-Pairs Bounded Edge Connectivity

Our work concerns algorithms for a variant of Maximum Flow in unweighted graphs. In the All-Pairs Connectivity (APC) problem, we are given a graph G on n vertices and m edges, and are tasked with computing the maximum number of edge-disjoint paths from s to t (equivalently, the size of a minimum (s, t)-cut) in G, for all pairs of vertices (s, t). Significant algorithmic breakthroughs have recently shown that over undirected graphs, APC can be solved in n2+o(1)\\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\usepackage{upgreek} \\setlength{\\oddsidemargin}{-69pt} \\begin{document}$$n^{2+o(1)}$$\\end{document} time, which is essentially optimal.

Lessons learned during online education experiences of kindergarten during the COVID-19 pandemic in Bangladesh

ABSTRACT This study explored the online education experiences of students, teachers and parents of kindergarten in Bangladesh during the emergency situation created by COVID-19. A qualitative research paradigm approach was followed. Students, teachers and parents of kindergartens from eight divisions of Bangladesh, one respondent of each category from each division, were selected through purposive sampling. Semi-structured interviews were conducted using mobile phones due to COVID-19. This study revealed that online education brought opportunities to engage students in academic activities and reduced education loss but created physical, psychological and video games addiction problems. Challenges that arose included device shortages, lack of training and technical skills, network connectivity problems, slow internet speed and the high-cost of internet data packages to implement the online education of kindergartens successfully. As the world comes out of the pandemic the learning acquired during this time informed possibilities for future online teaching in kindergarten including upskilling the early childhood workforce in this digital age.

Analysis of student perceptions relating to satisfaction from online learning during COVID-19 in Sikkim, India: The mediating role of motivation and attitude, and the moderating role of constraints

The objective of this study is to analyse the role that motivation and attitude play as mediators in the relationship between student satisfaction with online learning and comfort during COVID-19 pandemic in Sikkim, India. We define perceived comfort as the level of flexibility and convenience in using technologies for online learning. Motivation is defined as willingness and inspiration to learn. Attitude is defined as the student’s behaviour towards online learning platforms. And constraint is measured in terms of connectivity problem and data limitation in accessing online learning. A mediating and moderating model is developed and casual relationship is analysed between independent and dependent variable with the help of Macro process using IBM-SPSS software (Version 25). The study hypothesize that Motivation and Attitude of the students mediate the relationship between Comfort and Satisfaction from online learning and Constraints of online learning shall moderate the positive relationship between motivation and Satisfaction. For the study, an online data was collected from 403 students studying in various colleges and universities in Sikkim who were undergoing online classes during Covid-19 period. Models were formed to empirically examine and validate the positive relationship of comfort, motivation and attitude with level of satisfaction from online learning. The findings showed that in various higher educational institutions in Sikkim, the relationship between comfort and reported levels of satisfaction is partially mediated by both the degree of motivation and students' attitudes towards online learning. However, the moderating impact of Constraint is found to be negligible.

Simplified numerical model development for sophisticated analysis of lightweight-concrete encased cold-formed steel compressed column-end joints and panels

Since cold-formed steel (CFS) members are prone to complex buckling phenomena; that decrease their structural capability, many strengthening trends have been developed so far. One of these methods has been proposed as a new structural system comprising cold-formed steel (CFS) elements encased in polystyrene aggregate concrete (PAC). In this research, a simplified finite element model has been developed using ANSYS software, where a geometrically and materially nonlinear analysis with imperfections (GMNI) was used to solve the problem of PAC-encased CFS connections and panels subjected to compression. Each model was validated against available test results from literature. The full detailed volume-contact element-based model of concrete was replaced by spring elements perpendicular to the plate’s plane with equivalent properties, where a specific formula was set to define the stiffness of springs. A parametric study was performed to investigate in which range this stiffness has an impact on the ultimate load of the examined members. Additionally, different geometric imperfection amplitudes were implemented to test the real imperfection values. Finally, a failure mode-based equivalent geometrical imperfection amplitude was proposed to anticipate the design resistance of PAC-encased connections and panels.

Effects of online education on prosthetics orthotics education during COVID-19.

It is obvious that educational activities were affected globally due to the pandemic. This study was planned to examine the effects of online education on undergraduate degree (UD) and associate degree (AD) Orthotics and Prosthesis education in the COVID-19 pandemic. A crossectional online survey. The Google Forms questionnaire was delivered to students of Orthotics and Prosthesis in the level of undergraduate degree and AD and academicians conducted in the study. Next, the participants were reviewed regarding their knowledge about devices used for online education and related technical problems. A 5-point Likert-type questionnaire with 18 questions that was developed specifically for this study was applied to examine their views on online education. The study included 472 participants who had a mean age of 21.30 ± 0.22 years. Among the participants, 262 were AD students (55.5%). Approximately 82% of the participants were used their mobile phones for connection. The connection problems, and inappropriateness of online education in applied course, preference of online education for theoretical courses, insufficiency of digital course materials, failure to access education easily, insufficiency of online examinations for measurement and evaluation, and preference of homework over online education were stated by 79%, 88.3%, 41.9%, 54.5%, 70.1%, 41.7%, and 42.8% of the participants, respectively. Both academicians and students experienced connection problems, and applied courses were not suitable for online education. Motivation to attend the courses was low in online education, relevant workload increased, online examinations were not sufficient for measurement and evaluation, and studies were more unplanned. It is necessary to switch to formal education after the pandemic.

EFFECTIVENESS OF ONLINE YOGA SESSIONS ON WELLBEING OF UNDERGRADUATE HEALTH CARE STUDENTS: STUDENTS’ PERSPECTIVES

Context: A regular Yoga program for undergraduate healthcare students transitioned into an online mode due to restrictions of COVID-19 pandemic. All participants underwent six months of weekly Yoga training, of which three months were through online mode. Aim: To study the perception of undergraduate healthcare students on the effectiveness of online Yoga sessions on physical and mental wellbeing. Materials and Method: After six months of Yoga training, a survey questionnaire was developed, validated and shared with the participants as a Google form to assess the perceived effectiveness of online yoga sessions. A five-point Likert scale was used to assess the perceived effectiveness of the online Yoga sessions on physical and mental wellbeing, and open-ended questions assessed its perceived benefits and limitations, which were analysed thematically. Results: 124 undergraduate healthcare students completed the survey. The majority of participants rated online Yoga as beneficial for both mental and physical well-being, with 79.8% finding it helpful for their mental health and also 78.2% finding it helpful for their physical health. When comparing formats, 54.8% found online sessions helpful but less effective than offline ones, while 25.8% rated them equally effective. Thematic analysis revealed perceived advantages such as mental stability, convenience, and safety from practicing at home, as well as drawbacks like connectivity problems, distractions, space constraints, and a lack of in-person guidance. Conclusion: Participants found online Yoga sessions during the lockdown helpful for their physical and mental wellbeing. The majority of the participants felt that though the online Yoga sessions are helpful, they are less effective than offline, face-to-face interactive Yoga sessions.

During the pandemic, 81.3% had remote school activities, and 41.3% didnt go to therapies.

Medical education during the coronavirus disease 2019 pandemic: an umbrella review.

The coronavirus disease 2019 (COVID-19) pandemic affected many aspects of lifestyle and medical education during the recent years. We aimed to determine the impacts of COVID-19 pandemic on medical education to provide an overview of systematic reviews on it. We searched PubMed, Scopus, Web of Science, Cochrane library, Google Scholar, and medRxiv, with the following keywords: "SARS-CoV-2," "COVID-19," "Medical Education," "E-learning," "Distance Education," "Online Learning," "Virtual Education," "systematic review," and "meta-analysis," up to 15 April 2023. Studies were included if they were systematic reviews assessing the impacts of the COVID-19 pandemic on medical sciences students. We used A MeaSurement Tool to Assess systematic Reviews 2 (AMSTAR-2) checklist for quality assessment. A total of 28 systematic reviews were included. The eligible reviews included between five and 64 primary studies, ranging from 897 to 139,381 participants. Technology-enhanced learning and simulation-based learning were the most frequently used strategies. Virtual teaching has several drawbacks like technical difficulties, confidentiality problems, lower student involvement, connection problems, and digital fatigue. The overall satisfaction rate for online learning was above 50%. Also, favorable opinions about perception, acceptability, motivation, and engagement were reported. The quality of 27 studies were critically low and one was low. There were reduced clinical exposure and satisfaction for medical students during the pandemic. Further high-quality systematic reviews are required.

СІЛЬСЬКИЙ ТУРИЗМ ЧЕРКАЩИНИ: КОМУНІКАЦІЯ, ПАРТНЕРСТВО ТА КЛАСТЕРНА СПІВПРАЦЯ

The article examines rural tourism development in the Cherkasy Region and the possible diversification of the rural economy by analysing communication, partnership and cluster cooperation between entrepreneurs, local authorities, the community and educators. The theoretical block of the study is aimed at studying the concepts of "well-being", "rural area", "rural life", " neo-rural entrepreneurs ", "communication", "network connections", "partnership" and "cluster". The essence and content of the main concepts were revealed, as well as the connection between the concepts of "welfare" and "diversification", "communication" and "partnership", "neo-rural entrepreneurs" and "values of rural life" was established. The application block is based on the results of the hackathon "Diversification of rural economy through a network of public consultation centers of tourism" for active and interested representatives of Cherkasy Region. It has been established that mutual understanding, communication and support, joint work and learning are exactly the model of partnership that solves the problem of network connections, which in turn will lead to diversification of incomes, as well as increased well-being in rural areas, and can become the basis of cluster cooperation, which will allow rational use of the potential of local entrepreneurs to create a high-quality tourist service and product. A four-way partnership with the participation of entrepreneurs, the local community, local authorities and educators is precisely the combination of forces and resources that goes beyond the scope of ordinary business exchange and allows us to realize common goals and achieve success. The obtained conclusions can be the basis for further strategies regarding the diversification of the tourism-oriented rural economy in the region.

Blended Learning Experience during COVID-19 in Bangladesh: Rethinking the Barriers in the context of Higher Secondary Level Learners

The blended learning approach played a vital role to continue educational activities during COVID-19 pandemic in Bangladesh. The traditional face to face classroom teaching -learning system was totally disrupted during pandemic time. The educational activities were continued through different online platforms during pandemic time. Online instructions became popular and effective throughout the pandemic. Teaching -learning activities in different educational institutions in Bangladesh experiences manifold barriers at that time. The present paper aimed at rethinking the barriers of blended learning approach during COVID-19 in HSC level learners of Bangladesh. Randomly selected 360 respondents have been surveyed through a semi-structured survey questionnaire. This paper revealed that blended learning approach faced the problem of poor internet connection, challenge in two way communication, financial constraint, difficulties in presenting online presentation, submitting assignment, lack of experience regarding activity through internet, online group works, online apathy, fear in using internet, noisy environment etc. Finally, this study proposed some recommendations to overcome the barriers of blended learning approach in new normal situation in Bangladesh perspective.

Универсальность прав человека как агрегация закона и морали

Human rights, despite criticism of their universalism, are important for any person, regardless of his ethnic and racial affiliation, social status and religious views. One or another development of the discussion on the acceptability of a universal view of human rights, objectified in law, legislation and law enforcement, is embodied in the relationship of a person with the state and society and directly affects their well-being, security, ability to evolve and progress. Purpose. The main purpose of the article is to identify the role of the institution of human rights as a carrier of interrelated legal and moral prescriptions. Methodology. Causation of the problems of the functional connection of law, morality and fundamental rights of the individual is carried out by methods of theoretical synthesis and legal synergetics, which make it possible to actualize scientific knowledge about the universality and egalitarianism of human rights, the degree of perception of which by public consciousness and legislation strictly correlates with the processes dominating social dynamics and determining a particular state of public well-being and security. Results. Human rights are not a given, but the direction of society's development towards freedom, justice, equality, a necessary condition for the formation and functioning of the rule of law. Human rights impart morality to the law, strengthening the legitimacy of the legal norm; in turn, the law, relying on the universalism of these rights, gives moral prescriptions legal force. Combining the power of law and the properties of morality, human rights, recognized and protected by the state, allow society to come to certain, considered by a significant and most successful part of humanity to be the highest, legal forms of organization of the state.

Design and Improvement of the Connection Between the Steel Wire Rope and Shell for Cobalt-60 Afterloading Source Whip

This article studied a novel connection method between the steel wire rope and the outer shell of a cobalt-60 afterloading brachytherapy source delivery whip. The performance requirements for the connection between the steel wire rope and the shell are described by analyzing the structural characteristics and usage environment of the source whip. Multiple joint forms and process ideas are proposed and explored. After repeated testing and improvement, a set of embedded adhesive bonding connection methods is finally proposed. The small-diameter cobalt-60 afterloading radiation source whip produced by this method meets the requirements of experimental verification and clinical use, effectively solving the problem of connection between the radiation source shell and steel wire rope.

ЯЗЫК, СМЫСЛ, ОСОЗНАННОСТЬ: АСПЕКТЫ ОБУСЛОВЛЕННОСТИ

The question of correlation between languages of science and art should be considered in the context of solving a more general problem of connection between language, meaning, and the cognitive status of the receptivity realization in the process of a human’s individuation. An analysis of the prerequisites for the linguistic competence formation at the stage being ontogenetically earlier than the stage of isolated cognitive agents’ functioning, reveals new aspects of the contiguity of expressive resources and the experience that determines them. Reconstruction of some methodologically significant points of perceptive prenatal development introduces into epistemological discourse some layers of meanings that are innovative in their structure, fundamentally different from the structure of the contents that the subject manipulates in the postnatal period. Based on a logical-and-methodological analysis of the non-dual format of the implementation of cognition, the paper substantiates the possibility of a special kind of perceptualcommunicative procedures (expansion of consciousness, leap of awareness, «coming into being as a consciousness») that are capable of generating fundamentally new meaning schemas than those that a person uses in his individuated being-in-the-world. The mode of awareness leap as a basis of the linguistic competence formation becomes distinguishable in the optics of logical-and-methodological analysis of the non-dual stage of the perception coming into being. Such peculiar resources are correlated with the state of the subject’s cognitive integrity, when dissociation into thought and feeling, knowledge and beauty is not just absent, but is impossible. This is a state of indivisible mix of impressions, manifesting itself as a prerequisite, condition, source of formation of simultaneously fused meanings. Modal affiliation of these is not determined since the phenomenon of modal attribution at the stage of formation and functioning of such contents is not actualized. The proposed perspective of a deeper interpretation of the origins of the emergence of figurative and symbolic means of representing experience allows us to transform the optics of perception of a person’s cognitive potential in the context of more basic conditioning resources.
