ABSTRACT
This paper investigates the dynamics and drivers of informational inefficiency in the Bitcoin futures market. To quantify the adaptive pattern of informational inefficiency, we leverage two groups of statistics which measure long memory and fractal dimension to construct a global-local market inefficiency index. Our findings validate the adaptive market hypothesis, and the global and local inefficiency exhibits different patterns and contributions. Regarding the driving factors of the time-varying inefficiency, our results suggest that trading activity of retailers (hedgers) increases (decreases) informational inefficiency. Compared to hedgers and retailers, the role played by speculators is more likely to be affected by the COVID-19 crisis. Extremely bullish and bearish investor sentiment has more significant impact on the local inefficiency. Arbitrage potential, funding liquidity, and the pandemic exert impacts on the global and local inefficiency differently. No significant evidence is found for market liquidity and policy uncertainty related to cryptocurrency.
ABSTRACT
Objective To assess the experience of families and clinicians at a long term acute care hospital (LTACH) after implementing a written communication intervention. Methods Written communication templates were developed for six clinical disciplines. LTACH clinicians used templates to describe the condition of 30 mechanically ventilated patients at up to three time points. Completed templates were the basis for written summaries that there were sent to families. Impressions of the intervention among families (n = 21) and clinicians (n = 17) were assessed using a descriptive correlational design. Interviews were analyzed using thematic content analysis. Results We identified four themes during interviews with families: Written summaries 1) facilitated communication with LTACH staff, 2) reduced stress related to COVID-19 visitor restrictions, 3) facilitated understanding of the patient condition, prognosis, and goals and 4) facilitated communication among family members. Although clinicians understood why families would appreciate written material, they did not feel that the intervention addressed their main challenge – overly optimistic expectations for patient recovery among families. Conclusion Written communication positively affected the experience of families of LTACH patients, but was less useful for clincians. Innovation Use of written patient care updates helps LTACH clinicians initiate communication with families.
ABSTRACT
This study utilizes the enclosed and stable environment of underground space for long-term sustainable planning for urban epidemics and disasters. Owing to the COVID-19 epidemic, cities require long-term epidemic-disaster management. Therefore, this study proposed a strategy for integrating multiple functions to plan a comprehensive Underground Resilience Core (URC). A planning and assessment methods of URC were proposed. With this methodology, epidemic- and disaster- URCs were integrated to construct a comprehensive-URC in underground spaces. The results show: (1) Epidemic-resilient URCs adopting a joint progressive approach with designated hospitals can rapidly suppress an epidemic outbreak. (2) The regularity of the morphology of underground spaces determines the area of the URC. Bar-shaped underground spaces have the potential for planning disaster-URCs. (3) The URC planning efficiency ranking is as follows: Bar shapes lead overall, T shapes are second under seismic resilience, and Cross shapes are second under epidemic resilience. (4) The potential analysis of planning a comprehensive-URC in the underground parking in Chinese cities showed that the recovery time can be advanced from 29% to 39% and the comprehensive resilience can be improved by 37.63%. The results of this study can serve as sustainable urban planning strategies and assessment tools for long-term epidemic-disaster management.
ABSTRACT
This paper presented a brief introduction to the outbreak process and symptoms of coronavirus disease 2019 (COVID-19), elucidated the detection methods and transmission modes of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that caused the disease, and summarized the survival time of SARS-COV-2 in different media and different physical and chemical conditions and factors that could affect the long-term survival of the virus. This paper also summed up current risk assessments of SARS-COV-2 in food safety conducted in various countries, and concluded that the risk of SARS-COV-2 to food safety is very low, but preventive measures are still in need after referring to latest research. Finally, some methods to prevent SARS-COV-2 contamination in food were introduced, aiming to provide a basis for the formulation of policy measures in the future.Copyright © 2021, Shanghai Municipal Center for Disease Control and Prevention.

ABSTRACT
This article addresses selected issues relating to the current situation of Social Europe, examining a possible legal basis for a Directive on short-time work as proposed by Sylvaine Laulom. Subsequently, it discusses the legal basis for the proposed Directive on minimum wages, concluding that there is no sufficient legal basis in EU primary law as a result of Article 153 (5) Treaty on the Functioning of the European Union (TFEU). The article then provides a brief overview of developments in long-term care and collective bargaining for self-employed persons. Finally, it concludes with examples taken from Austrian case law of how the COVID pandemic can open up a new perspective for dealing with existing problems in labour and social security law. © 2023 Kluwer Law International BV, The Netherlands
ABSTRACT
Since the outbreak of COVID-19, the severe acute respiratory syndrome coronavirus 2 genome is still mutating. Omicron, a recently emerging virus with a shorter incubation period, faster transmission speed, and stronger immune escape ability, is soaring worldwide and becoming the mainstream virus in the COVID-19 pandemic. It is especially critical for the governments, healthcare systems, and economic sectors to have an accurate estimate of the trend of this disaster. By using different mathematical approaches, including the classical susceptible-infected-recovered (SIR) model and its extensions, many investigators have tried to predict the outbreaks of COVID-19. In this study, we employed a novel model which is based upon the well-known susceptible-infected-removed (SIR) model with the time-delay and time-varying coefficients in our previous works. We aim to predict the evolution of the epidemics effectively in nine cities and provinces of China, including A City, B City, C City, D City, E City, F City, G City, H City and I Province. The results show it is effective to model the spread of the large-scale and sporadic COVID-19 induced by Omicron virus by the novel non-autonomous delayed SIR compartment model. The significance of this study is that it can provide the management department of epidemic control with theoretical references and subsequent evaluation of the prevention, control measures, and effects.
ABSTRACT
Background: COVID-19 made many changes in life of persons and even after post COVID era these changes are integral to our life. Some of the changes were online classes, work from home, and online gaming. Computer work leads to static position of neck, shoulders, and upper limbs for extended hours. This leads to higher risk of developing visual, musculoskeletal and psychological problems. Aims and Objectives: The present study was carried out to determine prevalence of musculoskeletal health disorders, assess work distribution, and their probable interaction with musculoskeletal health problems in computer users of Ahmedabad city. Material(s) and Method(s): A cross-sectional study was carried out over a period of 1-year time among 800 participants to study the musculoskeletal problems among computer users. Result(s): Out of 800 participants, 76.75% of participants had any computer related musculoskeletal problem. If participants work more than 4 h in a single spell prevalence of musculoskeletal problems was 82.95%. Regular exercise has significant role in preventing computer-related musculoskeletal problems. Conclusion(s): Computer-related musculoskeletal problems have relation with number of hours spent in single spell, total daily working hours, and years of computer-related work.Copyright © 2023, Mr Bhawani Singh.

ABSTRACT
The number of Americans living with Alzheimer's and all other dementias continues to increase. Most of them will need long-term and community-based services as the disease progresses. While medical research is making advances, there is more work to be done to ensure that every person receives care that is person-centered and allows them to live with dignity and respect.
ABSTRACT
We situate the contemporary crisis of COVID‐19 deaths in seniors' care facilities within the restructuring and privatisation of this sector. Through an ethnographic comparison in a for‐profit and nonprofit facility, we explore what we identify as brutal and soft modes of privatisation within publicly subsidised long‐term seniors' care in Vancouver, British Columbia, and their influence on the material and relational conditions of work and care. Workers in both places are explicit that they deliver only bare‐bones care to seniors with increasingly complex care needs, and we document the distinct forms and extent to which these precarious workers give gifts of their time, labour and other resources to compensate for the gaps in care that result from state withdrawal and the extraction of profits within the sector. We nonetheless locate more humane and hopeful processes in the nonprofit facility, where a history of cooperative relations between workers, management and families suggest the possibility of re‐valuing the essential work of care.

ABSTRACT
Overcoming infection with coronavirus disease 2019 (COVID-19) can lead to the persistence of various symptoms in some patients. The complex of symptoms causally related to severe acute respiratory coronavirus 2 infection is called post-COVID syndrome. One of the most common respiratory complications is pulmonary fibrosis, especially after critical course of the disease. In some patients, ho-wever, only the peripheral airways are affected by the air-trapping seen on high-resolution computed tomography scans. Less common respiratory complications include sarcoidosis and pneumatoceles. This narrative review summarizes current knowledge about pulmonary involvement as part of post-COVID syndrome.
ABSTRACT
PurposeThis study aims to examine earnings management around initial public offerings (IPOs) in India. It also explores the influence of issue characteristics on earnings management around the IPOs.Design/methodology/approachA sample of 511 IPOs that came during April 2003-March 2019 is studied for calculating earnings management for pre-issue, issue and post-issue years. Using Cross-Sectional Modified Jones Model, the paper presents earnings management on the basis of three proxies i.e. discretionary accruals, discretionary current accruals and discretionary long-term accruals. The influence of issue characteristics on earnings management practised around the IPOs is also observed through correlation and multiple regression analysis.FindingsThe paper finds that earnings management is abnormally high during the issue year compared with pre-issue and post-issue years. It also unveils that profitability, premium, age, and size of the issuer significantly determine the level of pre-issue and issue year earnings management practised by Indian IPO issuers.Research limitations/implicationsThe findings are useful to stakeholders (potential investors, analysts and regulators) to observe, assess and understand the quality of financial numbers that are based on fallacious disclosure of accounting figures. It provides insight into the possibilities of managed earnings around the issue that could influence investors' decision-making. Further, the study reflects the efficacy of Indian regulatory norms for IPOs.Originality/valueTo the authors' knowledge, it is the only Indian study that had used an extensive data set of about two decades to calculate earnings management during pre-issue, issue and post-issue years. The uniqueness of the study further lies in three proxies of earnings management representing short-term and long-term accruals. Moreover, it is the first study to observe the influence of IPO issue characteristics on earnings management.
ABSTRACT
This book broadens the visioning on new care environments that are designed to be inclusive, progressive, and convergent with the needs of an aging population. The contents cover a range of long-term care (LTC) settings in a single collection to address the needs of a wide audience. Due to the recent COVID-19 pandemic, rethinking the spatial design of care facilities in order to prepare for future respiratory and contagious pathogens is one of the prime concerns across the globe, along with social connectedness and autonomy in care settings. This book contributes to the next generation of knowledge and understanding of the growing field of the design of technology, programs, and environments for LTC that are more effective in infection prevention and control as well as social connectedness. To address these issues, the chapters are organized in four sections: Part I: Home- and community-based care;Part II: Facility-based care;Part III: Memory care and end-of-life care;and Part IV: Evidence-based applied projects and next steps. (Re)designing the Continuum of Care for Older Adults is an essential resource for researchers, practitioners, educators, policymakers, and students associated with LTC home and healthcare settings. With diverse topics in theory, substantive issues, and methods, the contributions from notable researchers and scholars cover a range of innovative programming, environments, and technologies which can impact the changing needs and support for older adults and their families across the continuum of care.

ABSTRACT
The importance of care for our sustainability is increasingly discussed by policy makers and academics. For several reasons, however, the law has failed to address it. Accordingly, care has long been in a state of crisis, where the needs of those who require care are not met, and those who care are routinely subject to discrimination and cannot care in a dignified way. The Covid-19 Pandemic has highlighted the extent of the problem. The EU has responded by announcing on 7 September 2022 ‘A European Care Strategy for Caregivers and Care Receivers'. Although not flawless, this initiative is ground-breaking. It is now crucial to sustain momentum and to continue to build on this initiative. © 2023, The Author(s).
ABSTRACT
The COVID-19 (coronavirus disease 2019) pandemic has posed greater challenges to older adults, especially those who live in congregated long-term care facilities (LTCFs) in dense urban settings. These facilities struggle with high rates of COVID-19 infections and other challenges that undermine LTCF residents' well-being. These challenges, including social isolation and limited access to nature and community, have been exacerbated by the pressures of the pandemic. This has led to feelings of loneliness, depression, and other mental health issues among residents and a higher risk of psychological stress and infection among nurses. The pandemic has challenged the existing built environment of LTCFs. Issues regarding physical and mental health, quality of life (QoL), infection control, and pandemic resiliency have been shown to be increasingly interwoven. This chapter envisions innovative approaches toward a post-COVID-19 environment for older adults and their caregivers. This chapter provides an extensive review and synthesis of the lessons learned from LTCFs during the pandemic, with a focus on how their experience was impacted by design. The authors also draw from current design trends to identify their potential to support residents', staff, and visitors' needs during and after pandemics. From these learnings, the following design principles were developed: (1) small household model, (2) biophilic design, (3) intergenerational community, and (4) multi-tier infection control strategies. These design principles were then translated to a prototype through a graduate capstone studio project, which provides a visual illustration of how these evidence-based design solutions can be applied within a dense urban environment.

ABSTRACT
The need to vaccinate children under the age of 12 against COVID-19 remains an object of discussion today. The relatively low risk associated with infection in children and the ambiguous conclusions when comparing the effects of vaccination and the transferred disease are grounds to believe that the ratio of risk and benefit of vaccination in this age group is more complex. One of the key arguments in favor of vaccinating healthy children is to protect them from the long-term effects of COVID-19. In addition, socially significant factors such as a decrease in the spread of infection, the cost of vaccine supplies or damage associated with the organization of quarantine measures (including the closure of schools and the transfer of the educational process to a remote format) should be taken into account. The dynamics of the situation requires a constant reassessment of the risk and benefits of specific prevention in children. The purpose of this literature review is to systematize objective data concerning the foreign experience of vaccination of children against COVID-19;arguments for and against vaccination, which complicate the decision-making on the issue under study at one level or another.Copyright © 2023 The authors.
ABSTRACT
The article provides information about a study conducted to investigate the efficacy of doxophylline in post-COVID respiratory syndrome. The study was conducted on an outpatient basis at the Educational and Therapeutic Clinic of the Azerbaijan Medical University for 3 months in 2021-2022. The study included 47 patients with laboratory-confirmed COVID-19 pneumonia (PCR or rapid antigen test) and X-ray 4-12 weeks before the examination. In addition to general instrumental examinations, the intensity of cough was determined in patients - a questionnaire for assessing the severity of cough (Zhan W.), a modified dyspnea scale of the Medical Research Council and spirometry (FEV1 -ANHT1, EF, Tiffno index) examination. In accordance with the purpose of the work, post-COVID respiratory syndrome was confirmed in patients based on anamnestic-questionnaire scales and a spirometric examination performed at the beginning of treatment. After examination, all patients were prescribed doxofillin (Puroxan) 400 mg 2 times a day for 2 weeks. And for some patients who did not have a positive clinical and/or spirometric result, treatment was extended up to 8 weeks. During the study, all patients taking doxophylline showed a significant decrease in the intensity of cough and improvement in respiratory parameters. In conclusion, it can be considered appropriate to administer doxofylline at a dose of 400 mg to patients to improve respiratory parameters in post-COVID respiratory syndrome.Copyright © 2023 Ministry of Health.

ABSTRACT
First identified in December 2021, Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2)-the virus causing COVID-19, is responsible for significant morbidity and mortality rates. Given the worldwide impact of COVID-19, there is much interest in the anticipated long-term effects for those with history of SARS-CoV-2 infection. While initially presumed as a respiratory infection, there is now evidence of a broader array of pathophysiological mechanisms which result in a wide spectrum of reported acute and chronic symptoms in patients with confirmed COVID-19. These include including memory and other neurocognitive changes as well as psychiatric and behavioral symptoms. These nonspecific, but often debilitating, sequalaeare complex and difficult to disentangle from more common causes of neurobehavioral change. The goal of this chapter is to discuss anticipated chronic neurocognitive and psychiatric outcomes of COVID-19 survivors based on emerging peer-reviewed literature, data from prior pandemics, and outcome studies from well-characterized, clinically similar syndromes. This unpacking of long-term complications from COVID-19 will seek to set expectations and provide guidance for clinicians who will undoubtably encounter increased volumes of patients with residual post-COVID-19 neurobehavioral changes. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2022.
ABSTRACT
This chapter presents a novel model based on the operatorial approach for the spread of infections in a healthy population. The model efficiently describes the interactions between healthy and infected populations, and their transformation into recovered or deceased individuals. We apply our model to real situations, showing the efficacy of our method by analyzing Chinese data for SARS-2003 and COVID-19. Our model is in good agreement with the long-term behavior of the diseases, particularly in determining the number of infected and deceased individuals over time. Additionally, we demonstrate how the model can be easily adapted to account for lockdown measures, resulting in a drastic reduction of the number of infected individuals. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
