ABSTRACT

Purpose: This study aimed to investigate the impact of characteristic ischemic stroke and outcomes during the first COVID-19 pandemic lockdown. Patients and Methods: A retrospective, observational cohort study of a comprehensive tertiary stroke center was conducted. Patients with ischemic stroke were divided into pre-COVID-19 lockdown (11/1/2019 to 1/30/2020) and COVID-19 lockdown (1/31/2020 to 4/30/2020) period groups. Patient data on stroke admission, thrombolysis, endovascular treatment, and 3-month routine follow-up were recorded. Data analysis was performed using SPSS according to values following a Gaussian distribution. Results: The pre-COVID-19 lockdown period group comprised 230 patients compared to 215 patients in the COVID-19 lockdown period group. Atrial fibrillation was more predominant in the COVID-19 lockdown period group (11.68% vs 5.65%, p=0.02) alongside patients who were currently smoking (38.8% vs 28.7%, p=0.02) and drinking alcohol (30.37% vs 20.00%, p=0.012) compared with that of the pre-COVID-19 lockdown period group. For patients receiving thrombolysis, the median door-to-CT time was longer in the COVID-19 lockdown period group (17.0 min (13.0, 24.0) vs 12.0 min (8.0, 17.3), p=0.012), median door to needle time was 48.0 minutes (35.5, 73.0) vs 43.5 minutes (38.0, 53.3), p=0.50, compared with that of the pre-COVID-19 lockdown period group. There were no differences for patients receiving mechanical thrombectomy. The median length of hospitalization (IQR) was no different. Discharge mRS scores (IQR) were higher in the COVID-19 lockdown period group (1.0 (1.0, 3.0) vs 1.0 (1.0, 2.0), p=0.022). Compared with the pre-COVID-19 lockdown period, hospitalization cost (Chinese Yuan) in the COVID-19 period group was higher (13,445.7 (11,009.7, 20,030.5) vs 10,799.2 (8692.4, 16,381.7), p=0.000). There was no difference observed in 3-month mRS scores. Conclusion: Patients presenting with ischemic stroke during the COVID-19 pandemic lockdown period had longer median door-to-CT time and higher hospitalization costs. There were no significant differences in 3-month outcomes. Multidisciplinary collaboration and continuous workflow optimization may maintain stroke care during the COVID-19 pandemic lockdown.

ABSTRACT

Introduction During the Cov-19 pandemic, many studies reported a broad spectrum of cutaneous reactions presenting as erythematous rashes or pernio-like, urticaria-like or vesicular/bullous patterns associated with Cov-19-infection and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination. Methods The authors documented the clinical and histopathological features of an unexpected case of granuloma annulare (GA) arising a few days after the SARS-CoV-2 vaccination and reviewed all GAs reported in the literature following the SARS-CoV-2 vaccination and Cov-19-infection. Case report A 69-year-old woman developed a single reddish lesion on the left deltoid region, where the SARS-CoV-2 vaccine seven days earlier was injected. The clinicians performed a punch skin biopsy, and histology revealed an interstitial GA. Conclusions Clinicians should be aware of the potential, though rare, GA occurrence as a possible adverse event after the SARS-CoV-2 vaccination. This additional case, like what happens after the administration of other vaccines, supports the idea that GA may result from the immune system activation following the vaccination. However, notwithstanding, they should encourage their patients to obtain immunization to assist the public health systems in overcoming the COVID-19 pandemic.

ABSTRACT

We introduce an autonomous oxygen concentrator that was designed in Peru to fight the oxygen shortage produced worldwide as a consequence of the COVID-19 pandemic. Oxygen concentrators represent a suitable and favorable option for administering this gas at the patient's bedside in developing countries, especially when cylinders and tubed systems are unavailable or when access to them is restricted by lack of accessories, inadequate power supply, or shortage of qualified personnel. Our system uses a pressure swing adsorption technique to provide oxygen to patients at a flow rate of up to 15 l/min ± 1,5 l/min and a concentration of 93 % ± 3 %, offering robustness, safety and functionality. The quality measurements obtained from the validation process demonstrate repeatability and accuracy. The complete design files are provided in the source file repository to facilitate oxygen concentrator production in low and middle income countries, where access to oxygen is still a major problem even after the pandemic. Oxygen is part of the World Health Organization Model List of Essential Medicines and is perhaps the only medicine that has no substitute. This device can provide a reliable supply of oxygen for critically ill patients and improve their chances of survival.

ABSTRACT

Introduction Multiple sclerosis is associated with decrease in health-promoting behaviors (HPBs) and require appropriate nursing interventions. Telenursing can play an important role in education of patients during the COVID-19 pandemic in which face-to-face education is limited. This study aimed to investigate the effect of self-care education with telenursing approach on HPBs in patients with MS. Materials and methods In this clinical trial, 68 patients with MS were selected using simple random sampling from Jahrom MS Society and randomly assigned to the intervention (n = 34) and control (n = 34) groups. In the intervention group, educational sessions were held three days a week for six weeks. Data were collected using demographic information and Walker's Health-Promoting Lifestyle questionnaires before and immediately after the intervention. Data were analyzed by Mann-Whitney and Wilcoxon tests using SPSS software (Ver. 21). Results Based on the findings, immediately after the intervention, the mean score of HPBs was significantly higher (p = 0.005) in the intervention group (145.38 ± 26.66) than the control group (129.18 ± 22.35). The means of nutrition, exercise, health responsibility, and stress management were significantly different between the intervention and control groups immediately after the intervention (p < 0.05). Conclusion results this study indicated that self-care education with telenursing approach was effective on HPBs in patients with MS. It can be beneficial to employ as an educative-supportive approach in MS patients.

ABSTRACT

Objective The COVID-19 pandemic has caused a global health crisis disrupting healthcare delivery for people with severe obesity who have undergone bariatric surgery. This study examined the role of psychological distress during the first Italian COVID-19 lockdown in predicting post-operative outcomes in post-bariatric patients reaching the end of the 12–18 months follow-up during the lockdown. By using a person-centered approach, groups of patients with different psychological distress profiles were identified. We hypothesized that compared to post-bariatric patients with low psychological distress, post-bariatric patients with high psychological distress will be more at risk of weight regain. Methods A total of 67 patients (71.6% female, Mage = 45.9) participated in this observational retrospective cohort study. Patients' anthropometric data were gathered from medical records while the weight at the end of the lockdown through phone interviews. Psychological distress, operationalized with anxiety symptoms, depressive symptoms, and sleep disturbances, was assessed by an online self-report questionnaire. Results Significant differences were highlighted in the high and low psychological distressed group in weight changes, F(1,58) = 5.2, p < 0.001, η2 = 0.3. Specifically, compared to post-bariatric patients in the low psychological distress group, those in the high psychological distressed group reported weight regained (95% CI = 1.0, 2.6). Conclusion Results highlight the need to target post-bariatric patients with high psychological distress who are at risk for weight regain during the COVID-19 pandemic. Interventions mitigating psychological distress and obesogenic behaviors during future pandemics or in post-COVID times are needed in vulnerable post-bariatric patients reporting high psychological distress.

ABSTRACT

Objective While research found heterogeneous changes in mental health during the COVID-19 pandemic, less is known about the long term changes in mental health in psychiatric groups. Therefore, we applied a data-driven method to detect sub-groups with distinct trajectories across two years into the pandemic in psychiatric groups, and described their differences in socio-demographic and clinical characteristics. Method We conducted sixteen rounds of questionnaires between April 2020 and February 2022 among participants (n = 1722) of three psychiatric case–control cohorts that started in the 2000's. We used Growth Mixture Modelling and (multinomial) logistic regression to identify characteristics associated with trajectory membership. Results We found low decreasing (1228 [72%] participants), intermediate (n = 348 [22%] participants) and high stable (106 [6%] participants) trajectories of depressive symptoms;decreasing low/intermediate (1507 [90%] participants) and high stable (161 [10%] participants) trajectories of anxiety symptoms;and stable low (1109 [61%] participants), stable high (315 [17%] participants), temporary lowered (123 [9%]) and temporary heightened (175 [13%] participants) trajectories of loneliness. Chronicity and severity of pre-pandemic mental disorders predicted unfavourable sub-group membership for all outcomes. Being female, having a low education and income level were associated with unfavourable trajectories of depression, being younger with unfavourable trajectories of anxiety and being female and living alone with unfavourable trajectories of loneliness. Conclusion We found relatively stable trajectories of depression and anxiety symptoms over two years, suggesting low heterogeneity in outcomes during the pandemic. For loneliness, we found two specific sub-groups with temporary increase and decrease in loneliness during the pandemic.

ABSTRACT

Objectives We investigated the incidence (becoming distressed at the follow-up) and persistence (distressed at the baseline and the follow-up) of psychological distress among individuals with and without disability in the period from early 2017 (before the COVID-19 pandemic) to late 2020 (the second wave of the pandemic). Methods We analyzed the population-based FinHealth 2017 survey and its follow-up conducted in 2020 (number of individuals who participated in both surveys: n = 4881;age = 18+). Logistic regressions were applied to investigate differences in the incidence and persistence of psychological distress between people with and without disability. We also investigated whether age, quality of life at the baseline, and perceived increase in loneliness during the COVID-19 pandemic moderated the association between disability and the incidence of distress. Results The incidence of psychological distress was higher (OR = 3.01, 95% CI:2.09–4.35) for people with disability (18.9%) than among those without (7.4%), being highest (31.5%) among the youngest participants with disability, aged 18 to 39. People with disability who had a poor quality of life at the baseline were particularly prone to become distressed during the follow-up. People who reported perceived increase in loneliness during the pandemic were prone to become distressed at the follow-up regardless of their disability status. The persistence of distress was more common (OR = 6.00, 95% CI:3.53–10.12) among people with disability (65.7%) than among those without (24.9%). Conclusion The COVID-19 pandemic had more negative mental health effects on people with disability, especially adults with disability who were young and had a low quality of life before the pandemic.

ABSTRACT

Introduction Following the March 2020 federal declaration of a COVID-19 public health emergency, in line with recommendations for social distancing and decreased congregation, federal agencies issued sweeping regulation changes to facilitate access to medications for opioid use disorder (MOUD) treatment. These changes allowed patients new to treatment to receive multiple days of take-home medications (THM) and to use remote technology for treatment encounters—allowances that previously had been reserved exclusively for "stable” patients who met minimum adherence and time-in-treatment criteria. The impact of these changes on low-income, minoritized patients (frequently the largest recipients of opioid treatment program [OTP]-based addiction care), however, is not well characterized. We aimed to explore the experiences of patients who were enrolled in treatment prior to COVID-19 OTP regulation changes, with the goal of understanding patients' perceptions of the impact of these changes on treatment. Methods This study included semistructured, qualitative interviews with 28 patients. We used a purposeful sampling method to recruit individuals who were active in treatment just before COVID-19-related policy changes went into effect, and who were still in treatment several months later. To ensure a diverse array of perspectives, we interviewed individuals who either had or had not experienced challenges with methadone medication adherence from 3/24/21 to 6/8/21, approximately 12–15 months following the onset of COVID-19. Interviews were transcribed and coded using thematic analysis. Results Participants were majority male (57 %), Black/African American (57 %), with a mean age of 50.1 (SD = 9.3). Fifty percent received THM prior to COVID-19, which increased to 93 % during the pandemic. COVID-19 program changes had mixed effects on treatment and recovery experiences. Themes identified convenience, safety, and employment as reasons for preferring THM. Challenges included difficulty with managing/storing medications, experiencing isolation, and concern about relapse. Furthermore, some participants reported that telebehavioral health encounters felt less personal. Conclusions Policymakers should consider patients' perspectives to foster a more patient-centered approach to methadone dosing that is safe, flexible, and accommodating to a diverse array of patients' needs. Additionally, technical support should be provided to OTPs to ensure interpersonal connections are maintained in the patient-provider relationship beyond the pandemic.

ABSTRACT

Background There is paucity of data describing the impact of COVID-19 pandemic on antimicrobial resistance. This review evaluated the changes in the trend of multidrug resistant gram negative and gram positive pathogens during the COVID-19 pandemic. Methods A search was conducted in PubMed, Science Direct, and Google Scholar databases to identify eligible studies. Studies that reported the impact of COVID-19 pandemic on carbapenem-resistant Acinetobacter baumannii (CRAB), carbapenem-resistant Enterobacteriaceae (CRE), extended-spectrum beta-lactamase inhibitor (ESBL)-producing Enterobacteriaceae, vancomycin-resistant enterococci (VRE), methicillin-resistant Staphylococcus aureus (MRSA) and carbapenem-resistant Pseudomonas aeruginosa were selected. Studies published in English language from the start of COVID-19 pandemic to July 2022 were considered for inclusion. Results Thirty eligible studies were selected and most of them were conducted in Italy (n = 8), Turkey (n = 3) and Brazil (n = 3). The results indicated changes in the rate or incidence density of multidrug resistant bacteria pathogens and the changes varied between the studies. Most studies (54.5%) reported increase in MRSA infection/colonization during the pandemic and the increase ranged from 4.6% to 170.6%. Five studies (55.6%) reported a 6.8% to 65.1% increase in VRE infection/colonization during the pandemic. A 2.4% - 58.2% decrease in ESBL E. coli and a 1.8% – 13.3% reduction in ESBL Klebsiella pneumoniae was observed during the pandemic. For CRAB, most studies (58.3%) reported 1.54% – 621.6% increase in infection/colonization during the pandemic. Overall, studies showed increase in the rate of CRE infection/colonization during the pandemic. There was a reduction in carbapenem-resistant E. coli during COVID-19 pandemic while increase in carbapenem-resistant K. pneumoniae was observed. Most studies (55.6%) showed 10.4 – 40.9% reduction in the prevalence/incidence of CRPA infections during the pandemic. Conclusion There is limited data describing the impact of COVID-19 pandemic on antimicrobial resistance. Changes in multidrug resistant bacteria pathogens vary between countries and between the pathogens. The impact of improvement in hand and environmental hygiene may be counteracted by inappropriate use of antibiotics among COVID-19 patients. Limited evidence indicate that there is an increase in multidrug resistant gram negative and gram positive pathogens during COVID-19 pandemic. Both infection prevention and control strategies and antimicrobial stewardship should be strengthen to curtail the rising trend of multidrug resistant gram positive and gram negative bacteria.

ABSTRACT

In addition to dealing with language, communication and cultural barriers, international students in hospitality management were suddenly confronted with bleak career prospects in a sector crippled by the COVID-19 pandemic. Yet, little is known about how international students in hospitality management mobilize personal resources to cope with sudden career shock events. We address this question by developing and testing a model of career adaptability of international hospitality management students during the COVID-19 pandemic that focuses on the role of language communication competence. We draw from communication theory to argue that language communication competence enables international hospitality management students to appraise COVID-19 as presenting career opportunities that in turn motivate career adaptability contingent on cultural distance. Our results, based on a sample (n = 290) of international hospitality management students in Australia during the COVID-19 pandemic, support our contention. The theoretical and practical implications of our findings of the role of communicative behavior and cultural competence for coping with career transitions in periods of crises are fully discussed.

ABSTRACT

Widespread concerns have been raised about the huge environmental burden caused by massive consumption of face masks in the context of the COVID-19 pandemic. However, most of the existing studies only focus on the environmental impact associated with the product itself regardless of the actual usage scenarios and protective performance of products, resulting in unrealistic conclusions and poor applicability. In this context, this study integrated the product performance into the existing carbon footprint assessment methodology, with focus on the current global concerns regarding climate change. Computational case studies were conducted for different mask products applicable to the scenarios of low-, medium- and high-risk levels. The results showed that reusable cotton masks and disposable medical masks suitable for low-risk settings have a total carbon footprint of 285.484 kgCO2-eq/FU and 128.926 kgCO2-eq/FU respectively, with a break-even point of environmental performance between them of 16.886, which implies that cotton masks will reverse the trend and become more environmentally friendly after 17 washes, emphasizing the importance of improving the washability of cotton masks. Additionally, the total carbon footprints of disposable surgical masks and KN95 respirators were 154.328 kg CO2-eq/FU and 641.249 kg CO2-eq/FU respectively, while disposable medical masks and disposable surgical masks were identified as alternatives with better environmental performance in terms of medium- and high-risk environments respectively. The whole-life-cycle oriented carbon footprint evaluation further indicated that the four masks have greater potential for carbon emission reduction in the raw material processing and production processes. The results obtained in this study can provide scientific guidance for manufacturers and consumers on the production and use of protective masks. Moreover, the proposed model can be applied to other personal protective equipment with similar properties, such as protective clothing, in the future.

ABSTRACT

This study analyzes how the resources and capabilities of the owner-manager influence the firm's capacity to survive during crises. We conceptualize that only the deliberate use of available resources (bricolage) can enhance this capacity, and that "making-do” behaviors mediate the influence of the owner's social and human resources on the firm's capacity to survive crises. Based on a sample of 462 Chilean owner-managed small and medium enterprises (SME), we test our hypotheses using a complementary partial least squares-structural equation modeling (PLS-SEM) and fuzzy set-qualitative comparative analysis (fsQCA) approach. The results indicate that when founders deliberatively use their social and cognitive resources, they enhance the firm's capacity to survive in crisis environments. The fsQCA results complement these outcomes by showing that low levels of survival capacity are related to low levels of bricolage and founders' ties.

ABSTRACT

Objective To evaluate changes in mental health and well-being (eg, quality of work life, health, intention to leave) among nursing home managers from a February 2020 prepandemic baseline to December 2021 in Alberta, Canada. Design Repeated cross-sectional survey. Setting and Participants A random sample of nursing homes (n = 35) in urban areas of Alberta was selected on 3 strata (region, size, ownership). Care managers were invited to participate if they (1) managed a unit, (2) worked there for at least 3 months, and (3) worked at least 6 shifts per month. Methods We measured various mental health and well-being outcomes, including job satisfaction (Michigan Organizational Assessment Questionnaire Job Satisfaction Subscale), burnout (Maslach Burnout Inventory—exhaustion, cynicism, efficacy), organizational citizenship behaviors (constructive efforts by individuals to implement changes to improve performance), mental and physical health (Short Form–8 Health Survey), burden of worry, and intention to leave. We use mixed effects regression to examine changes at the survey time points, controlling for staffing and resident acuity. Results The final sample included 181 care managers (87 in the pre-COVID survey;94 in the COVID survey). Response rates were 66.9% and 82.5% for the pre-COVID and COVID surveys, respectively. In the regression analysis, we found statistically significant negative changes in job satisfaction (mean difference −0.26, 95% CI –0.47 to −0.06;P = .011), cynicism (mean difference 0.43, 95% CI 0.02-0.84;P = .041), exhaustion (mean difference 0.84, 95% CI 0.41-1.27;P < .001), and SF-8 mental health (mean difference −6.49, 95% CI –9.60 to −3.39;P < .001). Conclusions and Implications Mental health and well-being of nursing home managers worsened during the pandemic, potentially placing them at risk for leaving their jobs and in need of improved support. These findings should be a major concern for policy makers, particularly given serious prepandemic workforce shortages. Ongoing assessment and support of this understudied group are needed.

ABSTRACT

Present study aimed to explore adolescent depression trajectory during the COVID-19 pandemic, and the impact of parental style on it. Five-wave data of adolescent sample in China mainland were collected, and the group-based trajectory modeling was used to examine the theory constructs. Findings showed that, during the COVID-19 pandemic, there are four distinct patterns of change in depression symptoms over time, namely, resistance (72.3 %), recovery (15.3 %), increasing (6.7 %), chronic (5.7 %). Differences about the impact of parental style and grade on depression trajectory were found. Findings contribute to the knowledge of the impact of the COVID-19 pandemic on depression trajectory among general population, and parental style and grade should be considered in adolescent psychological intervention in the pandemic.

ABSTRACT

Background Influenza circulation reportedly declined during the COVID-19 pandemic in many countries. The occurrence of this change has not been studied globally, nor its potential drivers. Methods Change in the proportion of positive influenza samples reported by country and trimester was computed relative to the 2014-2019 period using the FluNet database. Random forests were used to determine predictors of change from demographical, weather, pandemic preparedness, COVID-19 incidence and pandemic response characteristics. A regression tree was used to classify observations according to these predictors. Findings during the COVID-19 pandemic the decline in influenza relative to pre-pandemic levels was global but heterogeneous across space and time. It was more than 50% for 311 out of 376 trimesters-countries and even more than 99% for 135. COVID-19 incidence and pandemic preparedness were the two most important predictors of decline. Europe and North America initially showed limited decline despite high COVID-19 restrictions;but strong decline afterwards as in most temperate countries where pandemic preparedness, COVID-19 incidence, and social restrictions were high;decline was limited in countries where these factors were low. The "zero COVID" countries experienced the greatest decline. These results set the stage for interpreting the resurgence of influenza worldwide.

ABSTRACT

Objectives This study aimed to determine the opportunities of and barriers to communicable diseases surveillance system (CDSS) during the COVID-19 pandemic and the extent to which the disease integrated into the CDSS in the Kurdistan region of Iraq. Study design A descriptive qualitative approach was applied. Methods We conducted seven semi-structured interviews and seven interviewee in a focus group discussion (FGD) with purposefully identified Key Informants (KI) from June to December 2020. All interviews were digitally recorded and transcribed verbatim. We adopted a mixed deductive-inductive approach for thematic data analysis, facilitated by using MAXQDA20 software for data management. Results Although the CDSS was considered appropriate and flexible, the COVID-19 was interpreted not to be integrated into the system due to political influence. The main concerns regarding core and support activities were the lack of epidemic preparedness, timeliness, and partial cessation of training and supervision during the pandemic. The existence of reasonable surveillance infrastructure, i.e., trained staff, was identified as an opportunity for improvement. The main challenges include staff deficiency, absence of motivation and financial support for present staff, scarce logistics, managerial and administrative issues, and lack of cooperation, particularly among stakeholders and surveillance staff. Conclusion Our findings revealed that the CDSS in the Kurdistan region requires substantial enhancement in epidemic preparedness, strengthening human resources, and logistics. the system can be developed by fostering meaningful intersectoral collaboration. We advocate that the health authorities and policy-makers prioritise the surveillance and effective management of communicable diseases.

ABSTRACT

One of the ultimate goals of the Green Economy is to move away from dependence on fossil energy, thereby achieving a sustainable development of a resource-saving and environment-friendly society. Thus, whether Green Economy stocks can hedge the risks of fossil energy markets, especially for natural gas market during recent crisis periods, is of great importance for both policy makers and portfolio managers. This paper identifies the time-varying connectedness and hedging effects of twelve NASDAQ OMX Green Economy sector stocks on NYMEX natural gas futures during three major turmoil events, i.e., European debt crisis, COVID-19 pandemic, and recent Russia-Ukraine conflict. The empirical results show that various Green Economy sector stocks can provide gratifying hedge effectiveness on the market risk of natural gas futures, and some of them can even perform similarly to gold and USD. Moreover, NASDAQ OMX Green Economy sector stocks offer better hedge effectiveness during recent Russia-Ukraine conflict than those of them in the periods of European debt crisis and COVID-19 pandemic. Finally, the Sharpe ratio results further show the important but time-varying roles of Green Economy sector stocks in hedging risks of natural gas market.

ABSTRACT

Background: As we live in the era of technology, it is clear that employees' technical skills and savviness are important to their work performance. With the COVID-19 pandemic, these qualities have become a "necessity‿ for many employees as they have switched to remote working. Less attention, however, has been given to empirical evidence regarding how employees' technological competencies influence their work outcomes during a forced shift to remote work. Integrating the theories of Job Demands-Resources and Conservation of Resources, this study sought to provide evidence regarding the joint effect of job/personal resources and technological competency on levels of employees' remote work engagement and performance. Method: A total of 131 teachers working in Turkey completed an online survey during the initial months of the COVID-19 pandemic. SPSS Process Macro (Model 7) was used for hypotheses testing. Results: We found partial support for the proposed moderated mediation model. Specifically, psychological resilience (as a personal resource) increased the level of work performance through work engagement and this relationship was stronger among employees with high levels of technological competency. However, the results did not provide support for the hypothesized interaction effect of workplace support (as a job resource) and technological competency on work performance through work engagement. Conclusion: This research advances the theoretical and empirical understanding of the role of technological competency in the motivational process of the Job Demands-Resources model. Our findings suggest that providing training activities aimed at promoting employee learning in the domain of online work tools can accelerate the effect of personal resources on work outcomes, especially during enforced remote working, as in the case of COVID-19. Résume Contexte: Comme nous vivons dans l'ère de la technologie, il est clair que les compétences techniques et le savoir-faire des employés, sont important pour leur rendement au travail. Avec la pandémie de COVID-19, ces qualités sont devenues une "nécessité‿ pour de nombreux employés qui sont passés au télétravail. Cependant, moins d'attention a été accordée aux preuves empiriques concernant la façon dont les compétences technologiques des employés influencent leurs résultats au travail pendant l'adaptation forcé au télétravail. En intégrant la théorie d'exigence ressources de l'épuisement professionnel et conservation des ressources, cette étude a cherché à fournir des preuves concernant l'effet conjoint du travail/ressources personnel et des compétences technologiques sur les niveaux d'engagement et rendement des employés au télétravail. Méthode: Un totale de 131 professeurs travaillant en Turquie ont répondu à un sondage en ligne pendant les premiers mois de la pandémie de COVID-19. Pour tester les hypothèses, le SPSS Process Macro (Model 7) a était utilisé. Résultats: Nous avons trouvé un soutien partiel pour le model de médiation modérée propose. Plus précisément, la résilience psychologique (en tant que ressource personnelle) a augmenté le niveau de rendement au travail grâce à l'engagement au travail, et cette relation était plus forte chez les employés ayant des niveaux élevés de compétence technologique. Cependant, les résultats n'ont pas démontré l'hypothèse de l'effet d'interaction du soutient en milieu de travail (en tant que ressource professionnelle) et des compétences technologiques sur le rendement au travail par le biais de l'engagement au travail. Conclusion: Cette recherche fait progresser la compréhension théorique et empirique du rôle de la compétence technologique dans le processus du modèle d'exigences-ressources de l'épuisement professionnel. Nos résultats suggèrent qu'offrir des activités de formations visant à promouvoir l'apprentissage des employés dans le domaine des outils de travail en ligne peut accélérer l'effets des ressources personnelles sur les résultats au travail, pa ticulièrement pour le télétravail forcé, comme ce fut le cas durant la pandémie de COVID-19.

ABSTRACT

This paper investigates the effects of macroeconomic policy announcements on financial markets in three Central European economies: Czechia, Hungary, and Poland (CE–3). We focus on the unprecedented stabilisation policies implemented from March to December 2020 during the COVID-19 pandemic, including unconventional monetary measures and large stimulus programs. Detailed categories of monetary and fiscal measures are introduced into vector autoregressions with exogenous regressors and dynamic conditional correlations, which we estimate using daily data. This allows us to control for policy spillovers from abroad, as well as global risk factors and pandemic-related variables. We find that, in general, macroeconomic policy measures implemented in the CE–3 countries played an important role in stabilising financial markets during the pandemic. We uncover several notable patterns in the reaction of markets to anti-crisis measures across the region. The impact of the monetary policy announcements on 10-year sovereign bond yields was more substantial than on stock market returns and exchange rate returns. The communication of the unconventional tools proved effective in lowering the bond yields. Interestingly, we document that the effects of non-standard measures for some variables, such as the exchange rate, can be qualitatively different from those resulting from a conventional monetary expansion. Even though the domestic monetary events became more important than the fiscal ones, the latter proved relevant for financial market returns, especially when large-scale immediate fiscal measures and tax deferrals were introduced. We also show that the CE–3 economies were subject to the cross-border transmission of policy announcement effects from the Euro Area and the US, although the magnitude of these effects was smaller than expected and varied across the CE–3 countries.
