ELASTIC: Edge Workload Forecasting based on Collaborative Cloud-Edge Deep Learning

With the rapid development of edge computing in the post-COVID19 pandemic period, precise workload forecasting is considered the basis for making full use of the edge limited resources, and both edge service providers (ESPs) and edge service consumers (ESCs) can benefit significantly from it. Existing paradigms of workload forecasting (i.e., edge-only or cloud-only) are improper, due to failing to consider the inter-site correlations and might suffer from significant data transmission delays. With the increasing adoption of edge platforms by web services, it is critical to balance both accuracy and efficiency in workload forecasting. In this paper, we propose ELASTIC, which is the first study that leverages a cloud-edge collaborative paradigm for edge workload forecasting with multi-view graphs. Specifically, at the global stage, we design a learnable aggregation layer on each edge site to reduce the time consumption while capturing the inter-site correlation. Additionally, at the local stage, we design a disaggregation layer combining both the intra-site correlation and inter-site correlation to improve the prediction accuracy. Extensive experiments on realistic edge workload datasets collected from China's largest edge service provider show that ELASTIC outperforms state-of-the-art methods, decreases time consumption, and reduces communication cost. © 2023 ACM.

Theorizing for Equity: Critical Approaches to Curricular Decision-Making

A longstanding history of curriculum in the United States verifies ongoing struggles in curricular decision-making, where questions such as "What is knowledge, who gets to decide what counts as knowledge, and how is knowledge assessed?" have been fundamental sources of debate. Instead of being oriented toward a dynamic, evolving sequence of learning experiences, the curriculum is often conceived as a static entity. However, the effects of the COVID-19 pandemic have presented the education field with an opportunity to remedy obsolete perceptions of the curriculum's purpose and, instead, reimagine and embrace an asset-based view of its future. Framed by Michel Foucault's (1971) concept of presenting a discipline's genealogy, this chapter reviews the field of memory, the field of presence, the field of concomitance, discontinuities and ruptures, and critical assumptions as they relate to curriculum leadership and development. While the field of memory consists of statements that are no longer considered true or valid, the field of presence includes concepts and practices which are acknowledged to be truthful and resonant, and the field of concomitance represents ideas or theories which have been transferred to other disciplines. In addition, discontinuities and ruptures include shifts in the discourse surrounding particular theories or viewpoints, and critical assumptions refer to theories of objectivity, reality, and truth which require a critical examination to avoid outcomes that result in norms and normalization. © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2022.

The impact of COVID-19 on access to mental health services and the use of teletherapy as an alternative form of treatment

The aim of this research study is to determine the impact of COVID-19 on access related to mental health services and also explain the use of teletherapy as an alternative form of treatment. This research study is based on secondary research data analysis to determine the research study data collected from websites related to the ratios of COVID-19 also that mental health services. Determine the research study used E-views software, and the generated result included descriptive statistics, correlations, the dickey fuller test analysis, the histogram, and state, also that explain the variance and test of equality between them.

Bidirectional Associations of Awareness of Age-Related Change and Attitudes Towards Own Aging With Social Media Use.

OBJECTIVES: We test whether higher awareness of age-related gains (AARC-gains), lower awareness of age-related losses (AARC-losses), and more positive attitudes towards own aging (ATOA) are cross-sectionally related to more frequent social media use. We also investigate the strength and direction of the associations of AARC-gains, AARC-losses, and ATOA with social media use over one-year, from before to after the onset of the COVID-19 pandemic. METHODS: We used cross-sectional data of 8320 individuals (mean age= 65.95 years; SD= 7.01) and longitudinal data of a subsample of 4454 individuals participating to the UK PROTECT study in 2019 and 2020. We used ordered regression models, linear regression models, and tests of interaction. Models were adjusted for age, sex, education, and employment. RESULTS: Higher AARC-gains and more positive ATOA, but not AARC-losses, were cross-sectionally associated with more frequent social media use. Social media use become more frequent at follow-up. In the longitudinal models controlling for baseline levels of the outcome variable, more frequent baseline social media use predicted increases in AARC-gains, whereas baseline AARC-gains did not significantly predict frequency of social media use at follow-up. Baseline frequency of social media use did not significantly predict AARC-losses, nor ATOA at follow-up, whereas lower levels of AARC-losses and more positive ATOA predicted more frequent social media use at follow-up. DISCUSSION: Although effect sizes were small, decreasing negative views on aging may help increase engagement of middle-aged and older people with social media. At the same time, fostering social media use could promote positive self-perceptions of aging.

University students' living conditions during the COVID-19 pandemic and predictors of their subjective health views: A cross-sectional survey.

This study aimed to explore the factors influencing subjective health views based on the living conditions and concerns of university students during the coronavirus infection 2019 (COVID-19) pandemic. From March to April 2021, a questionnaire survey was administered to 8,547 Japanese university students, and logistic regression analysis was used to explore factors related to subjective health views. The results showed that satisfaction with quality of sleep (OR = 2.651, 95% Cl 2.370-2.966,p < 0.001), satisfaction with university life (OR = 2.486, 95%Cl 2.215-2.789, p < 0.001), satisfaction with diet (OR = 1.849, 95% CI: 1.496-2.285, p < 0.001), regular exercise (OR = 1.759, 95% CI: 1.594-1.941, p < 0.001), consciousness of nutritional balance (OR = 1.276, 95% CI: 1.147-1.420,p < 0.001), eating breakfast every day (OR = 1.247, 95% CI: 1.121-1.387, p < 0.001), and consuming soft drinks at least once a week (OR = 0.865, 95% CI: 0.755-0.966, p = 0.010) were positive factors for subjective views of health. On the other hand, anxiety about whether the necessary credits can be obtained (OR = 0.885, 95% CI: 0.799-0.980, p = 0.019), infection from minimal outings (OR = 0.881, 95% CI: 0.794-0.976, p = 0.016) building and maintaining friendships on campus (OR = 0.867, 95% CI: 0.767-0.980, p = 0.023), and being able to continue working (OR = 0.713, 95% CI: 0.640-0.795, p < 0.001) were identified as negative factors. To ensure a healthy university life during the COVID-19 pandemic or future pandemic, supports tailored to students' living conditions and measures to address their anxieties are required.

Arima Models to Forecast Covid-19 in Kingdom of Saudi Arabia during the Interval (1-2021 to 1-2022) Weekly Using E-Views Program

The main objective of this research is to analyze the fundamental differences in the basic indicators of the emerging corona virus, COVID-19, especially the number of total cases and the number of deaths resulting from it in Kingdom of Saudi Arabia, in order to evaluate the precautionary measures taken by KSA. In this research, time series models were studied to predict the number of cases infected with COVID-19 that can be expected weekly in KSA during a period spanning a whole year using the numbers of weekly infections (WC) in KSA during the period from January 2021 to January 2022. The future values of injuries and deaths resulting from them were predicted using the time series method according to the current and previous values, and the E-Views statistical software package was used, which was specifically designed to process time series data. The study proved that there were statistically significant differences in the number of weekly infections with the corona virus, in addition to the presence of statistically significant differences in the number of weekly deaths resulting from the corona virus in Kingdom of Saudi Arabia. The study also demonstrated the existence of a statistically significant correlation between the number of weekly infections with the corona virus and the deaths resulting from it in Kingdom of Saudi Arabia. The automatic regression integrated moving average (ARIMA) model was used as one of the time series prediction methods and the prediction procedures were determined using the ARIMA model. The results of the analysis showed that the ARIMA(1, 2, 0) model gave the best results for prediction and data analysis. It is highly advised to maintain the social distancing with all safety measures.

Attitudes Towards COVID-19 Contact Tracing Apps: A Cross-National Survey

To help prevent the spread of COVID-19, countries around the world have implemented a range of measures and virus containment strategies, including digital contact-tracing (DCT) in the form of smartphone apps. While early studies showed a high level of acceptability of such technologies, the adoption rates varied greatly between countries after contact-tracing apps became available to download. This cross-national user survey (n=871) aims to explore public attitudes and factors that affect user acceptability and adoption of contact-tracing apps in the USA, UK, and the Republic of Ireland, which employ similar underlying technology, but have uneven adoption rates. The results indicate interactions between installation decisions and public trust in actors and institutions communicating COVID-related information, and releasing such technologies. Beyond the immediate case of contact tracing, our findings hold implications for the deployment and communicative framing of technology for public health and the public good, and inform the design of crisis response public health information systems.

Science Teaching at a Distance in Greece: Students' Views

This article presents in a comparative way the findings from two surveys conducted on primary (students in Y6) and secondary (students in Y10) students in Attica, Greece, in order to map their views on distance science education, which was emergently implemented due to the COVID-19 outbreak during the school year 2020–2021. The research was conducted in a sample of 378 primary and 197 secondary students. The findings revealed that students were not satisfied with the distance teaching and learning of science, either in primary or in secondary education, except for the increased use of audiovisual material. Technical issues, such as poor network and infrastructure, lack of face-to-face interaction with classmates and teacher, external and internal distractions, lack of sufficient experimental activities, and limited understanding of concepts were common findings in both levels of education. Concerning the differences between the levels, it seems that in primary education more technical problems were reported, while in secondary education more didactic problems were reported.

Pre-service mathematics teachers' views of nature of science in the context of COVID-19

A framework for K-12 science education (National Research Council [NRC], 2012) supports science learning on social and political issues to make informed decisions and solve problems. Socio-scientific issues have been considered as a context to teach characteristics of nature of science (NOS). This study is a qualitative study in nature to examine how pre-service mathematics teachers define science and address different aspects of science and scientific literacy in the context of coronavirus (COVID-19). Data sources included written reports and reflections on basic science-related questions. Responses from 50 pre-service mathematics teachers were analyzed through thematic analysis. The results indicated that pre-service mathematics teachers defined science as a product in the form of systematic knowledge, fact or theories-laws-models, and they provided informed or partially informed views on empirical, sociocultural, tentativeness, and subjectivity aspects by referring to cognitive, developmental, and sociocultural dimensions of science literacy. Pre-service mathematics teachers' definition of science as accumulated knowledge was not aligned with their desirable views on aspects of NOS. The study suggests possible implications for further studies. © 2023 by authors;.

How students view online knowledge: Epistemic beliefs, self-regulated learning and academic misconduct

The use of the internet in education has been greatly encouraged by the COVID-19 epidemic. Studying students' internet-specific epistemic beliefs (ISEB) and possible correlates would benefit online teaching and learning. However, little research has been conducted in this field. Therefore, we investigated the current status of ISEB among college students and considered the impact of self-regulated learning (SRL) and e-academic dishonesty (e-AD) on ISEB. A survey research method and convenience sampling were employed. A total of 538 Chinese college students completed the self-reported questionnaire. Our results indicate that although no significant differences were found in ISEB in terms of gender and academic major, students with different backgrounds also differed in e-AD experience and SRL. Three dimensions of ISEB were negatively correlated with SRL, while one had a significant positive correlation. In addition, the latter dimension of ISEB was negatively correlated with e-AD. Finally, SRL and e-AD jointly significantly predicted students' different ISEB, with explanatory power ranging from 14% to 36%. Study techniques of SRL were common predictors that could negatively predict the certainty, simplicity, and source of ISEB and positively predict justification. Based on the results, specific methods for schools, teachers and librarians to enhance students' ISEB are provided. © 2023

Voice from the frontline and learning for the future: A qualitative descriptive study on wider perspectives of frontline nurses in India during the COVID 19 global pandemic.

Objective: This study was conducted to explore frontline nurses' experiences of the impact of COVID 19 pandemic and suggestions for improvement in the healthcare system, policy and practice in the future. Method: A qualitative descriptive design was used. Frontline nurses who were involved in providing care to patients affected with COVID 19 in four designated COVID units from the Eastern, Southern and Western regions of India were interviewed during January to July 2021. Interviews were audio-recorded and transcribed manually by researchers from each region and thematically analysed. Result: Twenty-six frontline nurses aged between 22 and 37 years with a range of 1-14 years of work experience following a Diploma or Bachelor's degree in Nursing and Midwifery and working in the COVID units of selected regions in India participated in the study. Three key themes emerged: 'Physical, emotional and social health - an inevitable impact of the pandemic' described effects of the pandemic on nurses' health and wellbeing; 'Adapting to the uncertainties' narrated how nurses accommodated to the uncertainties during the pandemic; and 'An agenda for the future - suggestions for improvement' emphasised on practical strategies for the future. Conclusion: The inevitability of the pandemic had an influence at a personal, professional, and social level with learning for the future. The findings of this study have implications for healthcare system and facilities by enhancing resources, supportive environment for staffs to cope with the challenges imposed by the crisis and ongoing training to manage life threatening emergencies in the future.

Physicians' views on optimal use and payment system for telemedicine: a qualitative study.

BACKGROUND: Telemedicine is already in use in daily practice, but appropriate reimbursement and physician payment is falling behind in many countries. One reason is the limited availability of research on the matter. This research therefore examined physicians' views on the optimal use and payment modalities for telemedicine. METHODS: Sixty-one semi-structured interviews were conducted with physicians from 19 medical disciplines. Interviews were encoded using thematic analysis. RESULTS: Telephone and video televisits tend not to be used as a first patient contact, except for triage of patients in urgency situations. Several minimum required modalities for the payment system of televisits and telemonitoring were identified. For televisits these were: (i) remuneration of both telephone- and videovisits to increase healthcare equity, (ii) little or no differentiation between videovisit and in-person visit fee to make videovisits financially attractive and sustainable for physicians, (iii) differentiation of televisit fee per medical discipline, and (iv) quality requirements such as mandatory reporting in the patient's medical file. The identified minimum required modalities for telemonitoring were: (i) an alternative payment scheme than fee-for-service, (ii) remunerating not only physicians but also other involved health professionals, (iii) designating and remunerating a coordinator, and (iv) distinguishing sporadic vs. continuously follow-up. CONCLUSIONS: This research investigated the telemedicine usage behavior of physicians. Moreover, several minimum required modalities were identified for a physician-supported payment system of telemedicine, as these innovations necessitate challenging and innovation of the healthcare payment systems as well.

Sociocultural and Behavioral Features of Anticipated COVID-19 Vaccine Acceptance in Papua New Guinea: Protocol for a Mixed Methods Study.

BACKGROUND: COVID-19 was characterized by the World Health Organization (WHO) as a pandemic in 2020. Papua New Guinea (PNG) has remained on high alert ever since, and its National Control Centre continues to coordinate national preparedness and response measures, guided by its Emergency Preparedness and Response Plan for COVID-19. As part of the WHO and the Global Alliance for Vaccines and Immunization's COVID-19 Vaccines Global Access (COVAX) program, PNG received several shipments of COVID-19 vaccine doses. A nationwide vaccine rollout for COVID-19 was initiated in PNG in May 2021. Despite the availability of vaccines and the capacity of health systems to vaccinate frontline workers and community members, including high-risk groups, there are still critical issues related to vaccine safety, confidence, and acceptance to ensure the effectiveness of the COVID-19 vaccination campaign. Evidence from studies on COVID-19 vaccine acceptance and demand in low- and middle-income countries (LMICs) suggests that sociocultural characteristics of the community and the behaviors of different vaccine stakeholders, including vaccine recipients, vaccine providers, and policymakers, determine the effectiveness of vaccination interventions or strategies. OBJECTIVE: This study will examine sociocultural determinants of anticipated acceptance of the COVID-19 vaccine in urban and rural areas of different regions in PNG and health care providers' views on vaccine acceptance. METHODS: The study design uses a mixed methods approach in PNG's coastal and highlands regions. The first research activity will use a qualitative methodology with an epistemological foundation based on constructivism. This design elicits and listens to community members' accounts of ways culture is a rich resource that provides meaning to the COVID-19 pandemic; the design also measures adherence to niupela pasin ("new normal" in Tok Pidgin) and vaccination acceptance. The second activity will be a cross-sectional survey to assess the distribution of features of vaccine acceptance, priorities, and practices. The third activity will be in-depth interviews of health care providers actively involved in either COVID-19 clinical management or public health-related pandemic control activities. RESULTS: The project proposal has been reviewed and approved by the Medical Research Advisory Committee of Papua New Guinea. Qualitative data collection started in December 2022, and the survey will begin in May 2023. The findings will be disseminated to the participating communities later this year, followed by publication. CONCLUSIONS: The proposed research on community views and experiences concerning sociocultural and behavioral features of acceptance of the vaccine will provide a better understanding of communication and education needs for vaccine action for COVID-19 control in PNG and other LMICs. The research also considers the influence of health care providers' and policy makers' roles in the awareness and use of the COVID-19 vaccine.

Priming close social contact protective behaviors enhances protective social norms perceptions, protection views, and self-protective behaviors during disasters.

Many people do not make choices that minimize risk in the face of health and environmental threats. Using pre-registered analyses, we tested whether a risk communication that primed perceptions about health-protective preparation and behavior of close social contacts promoted protection views and protective behaviors. From December 10-24, 2020, we fielded a 2 (threat vignette: wildfire or COVID-19) x 3 (social contact prime: control, inaction, or action) experiment to a representative sample of 1,108 California residents facing increased COVID-19 cases/deaths, who had recently experienced the most destructive wildfire season in California history. Outcome variables were protection views and protective behavior (i.e., information seeking). Across threat conditions, stronger social norms, efficacy, and worry predicted greater protection views and some protective behaviors. Priming social-contact action resulted in greater COVID-19 information-seeking compared to the control. In the wildfire smoke condition, priming social contact action and inaction increased perceived protective behavior social norms compared to the control; social norms partially mediated the relationships of priming with protection views and protective behaviors; and having existing mask supplies enhanced the relationship between priming inaction and greater protection views compared to priming action or the control. Findings highlight the importance of social influence for health protection views and protective behaviors. Communications enhancing social norms that are sensitive to resource contexts may help promote protective behaviors.

Multi-view POI-level Cellular Trajectory Reconstruction for Digital Contact Tracing of Infectious Diseases

Digital contact tracing is an effective solution to prevent such a pandemic, but the low adoption rate of a required mobile app hinders its effectiveness. A large collection of cellular trajectories from mobile subscribers can be an out-of-the-box solution that is free from the low adoption issue, but has been overlooked due to its low spatial resolution. In this paper, to increase the resolution of this cellular trajectory, we present a new problem that estimates the user's visited places at the point-of-interest(POI) level, which we call POI-level cellular trajectory reconstruction. We propose a novel algorithm, Pincette, that accomplishes more accurate POI reconstruction by leveraging various external data such as road networks and POI contexts. Specifically, Pincette comprises multi-view feature extraction and GCN-LSTM-based POI estimation. In the multi-view feature extraction, Pincette extracts three complementary features from three views: efficiency, periodicity, and popularity. In the GCN-LSTM-based POI estimation, these three views are seamlessly integrated, where spatio-temporal periodic patterns are captured by graph convolutional networks (GCNs) and an LSTM. With extensive experiments on two real data collections of two cities, we show that Pincette outperforms four POI estimation baselines by up to 21.20%. We believe that our work sheds light on the use of cellular trajectories for digital contact tracing. We release the source code at https://github.com/kaist-dmlab/Pincette. © 2022 IEEE.

Attitudes and the lived experiences of vaccine hesitant parents: A mixed-methods study

Vaccine hesitancy (VH) refers to refusing or delaying vaccinations for reasons other than medical contraindications. Despite the significant benefits vaccines have provided since their invention, VH rates are still high worldwide. This concurrent mixed method study explored attitudes, and the lived experiences of vaccine hesitant parents of children of ages 0 to 18 who sought health care services in a Federal Qualified Health Center (FQHC) in the Mid-Atlantic region of the US. Quantitively results of this study revealed seven attributes of vaccine-hesitant parents: (1) the belief that children should get fewer shots at the same time, (2) concerns about children developing severe side effects from shots, (3) concerns about the safety of vaccines, (4) concerns that shots may not prevent the illnesses they are intended to prevent, (5) children get more shots than necessary, (6) illnesses that shots prevent are not severe, and (7) children should get immunity by getting sick rather than getting shots. Qualitative findings revealed four themes about the lived experiences of vaccine hesitant parents: (1) vaccines are not safe, (2) vaccines are not necessary, (3) parents are not well informed about the vaccines, and (4) children get too many shots. Recommendations for future research include conducting this study in a similar setting using the same methodology in the absence of the COVID-19 pandemic and conducting the study in more diversified settings to test the reproducibility of this study's findings.

Readiness for the Fourth Industrial Revolution

This chapter explored the readiness of a South African university to take part in the fourth industrial revolution by exploring the experiences of students in science and technology on the impact of COVID-19 in the learning of their practical modules. Guided by two research questions, namely how the COVID-19 has impacted students' engagement with their practical modules and students' readiness to learn remotely and carry out the practical aspects of their modules, the chapter employ a qualitative case study approach to explore the views of students that offer courses that involve practical. Seven fourth-year students were purposively selected as study sample. Data were generated online using Google forms and were analysed thematically. The chapter was framed using the technology acceptance model. Findings revealed the following: ease and clarity of concept, lack of interaction with others, lack of motivation, lack of access to ICT facilities, lack of relevant materials to execute practical tasks, and lack of conducive learning environment.

Multi-view Layout Design for VR Concert Experience

Owing to the COVID-19 pandemic, concerts are gradually being held online. Beyond live-streaming, it has recently become popular to utilize various realistic video technologies to add entertainment value and immersion to online concerts. We conducted a multi-view layout design study in a virtual reality environment with a head-mounted display to help users effectively explore and immerse themselves in multiple videos from various angles. Based on an analysis of an existing user interface for multi-view navigation and the characteristics of virtual reality, we proposed four layouts, i.e., 1) an evenly divided space, 2) an evenly divided designated space, 3) a widget type, and 4) an avatar type. We implemented a prototype by applying Korean pop concerts, where multi-view videos are the most actively utilized, and then conducted a user study to evaluate the usability and preferences of the proposed layouts. The results show that it is adequate to arrange the multi-view videos within a 60° to 110° space and on the left and right side of the main view, which is a range that the users can comfortably access. In addition, when placing multiple videos in a designated space, it is helpful to use visual effects or simple avatars to avoid visual burden being placed on the users. © 2022 ACM.
