ABSTRACT

The Covid-19 pandemic has profoundly impacted all areas of our private and public lives, including how we travel and how our goods reach their final destinations. The Covid-19 pandemic is affecting our mobility and transportation functions in unprecedented ways. It serves as a reminder of the importance of the movement of people and goods to our economy and society, but also of the industry's structural weaknesses. The supply chain has been strongly impacted by the devastating effects caused by the spread of the Covid-19 pandemic on the global economy. The degree of impact of these effects has reached companies' supply chains, particularly in terms of transport activity. For this, We carried out a study on the impact of transport activity on the supply chain of 196 Moroccan companies during the spread of the Covid-19 Virus. Thanks to the Chi-square test and the non-parametric Kruskal-Walis test, we found that the supply chain was significantly impacted by the disruption of this activity, particularly in terms of supply, purchase, and transport of goods ( p < 0.01) and a weak effect on production (p < 0.1). We found that the level of the chain disturbance is related to the nature of the transport. The upstream of the supply chain was impacted by the disruption of the transport of information while the downstream of the supply chain was influenced by the transport of goods.

ABSTRACT

Background: The coronavirus disease 2019 (COVID-19) pandemic has had a significant impact on international trade and supply chains. Border closures and reduced demand for traded goods provoked demand and supply shocks in supply chains, including those of the Southern African Development Community (SADC). Continued vulnerability of regional supply chains affects the long-term socio-economic development trajectory of the SADC. Objectives: This article investigates whether supply chains and their various components have exacerbated the pandemic’s trade impact, with specific reference to the SADC. The objective is to inform regional development policy interventions to improve the resilience of the SADC supply chains in future disturbances. Method: An econometric analysis was conducted to determine the relationship between supply chain efficiency (and the various sub-indicators) and the impact of the pandemic on merchandise trade volumes. The latter constitutes the dependent variable of the analysis and is quantified by measuring the deviation from the pre-shock growth path in the base year (2020) of the pandemic. Data sets from the UNCTADstat database were used. The independent variables are the sub-indicators that form part of the Logistics Performance Index (LPI), the data of which are sourced from the World Bank (2022). In addition to the chi-square test of homogeneity and the Shapiro–Wilk test of normality, regression analyses were conducted to determine the significance of the independent variables, in addition to their association and correlation with the dependent variable. Results: The analysis indicates that supply chain efficiency and components related thereto, including customs clearance, infrastructure, international shipments, logistics competence, tracking and tracing and lead time, are of high significance to and correlate with the impact of the pandemic. Conclusion: Regional development policy in the SADC should prioritise the targeted improvement of specific physical and non-physical infrastructure to support the development of efficient and resilient supply chains. Interventions should focus on improving border and customs processes and tracking and tracing capabilities of logistics service providers. This will contribute to the achievement of regional development objectives and catalyse the competitiveness of the SADC in the face of increased supply chain regionalisation.

ABSTRACT

Our research was intended to find out whether social networking is recognized and experienced as leisure or should be considered liquid leisure because its borders are fluid. This aim was connected to the broader question of whether there are still clear borders between work, leisure, and other life aspects. The research was designed as a cross-sectional ex-post-facto study. The survey examined data collected through a structured questionnaire completed and returned by 3451 respondents aged 15+ selected from the general population of the Czech Republic. The statistical significance of hypotheses was tested using χ2 statistics for two-way (C × R) and three-way (C × R × L) contingency tables. Only 752 (21.79%) respondents reported not having or using an online social network account. Even though there is no reason why social networking should not be considered leisure, there was a considerable discrepancy between those who considered social media a leisure activity (8.2%) and those who did not (78.21%). Therefore, this kind of leisure activity is conceptualized in this paper as a specific liquid leisure.

ABSTRACT

This article discusses one of the most important social factors of climate protection: climate concern. Most research in this area focuses on North America and Western Europe or presents international comparative statistics. Our work is innovative because we have designated a lesser-known post-socialist region in East-Central Europe as a sample area, and we intend to conduct in-depth analyses at the municipal level. Our study describes the second largest city in Hungary, Debrecen, and its agglomeration. Based on a questionnaire survey in 2020 (N = 512), we examined opinion factors, and we have presented features consistent with or different from the findings in the relevant literature. In the statistical analysis, chi-square tests and binary logistic regressions were applied to reveal significant differences between the responses of different types of respondents. As response variables, we used the questions about general concerns regarding air pollution, knowledge about climate change, beliefs about tackling, perceived threat, behavioural responses, personal actions, and demography. We found that the concern about air pollution and a feeling of threat to respondents’ life was mainly affected by the degree of climate concern. We conclude that the knowledge of local communities on climate change has increased, and risk perception has improved. Still, there is no clear relationship between the level of concern and climate-conscious behaviour. The findings provide ideas for promoting local climate management and awareness-raising in the European Union or other countries.

ABSTRACT

This study aimed to identify the association between social frailty and health-related quality of life (HRQoL) and to identify the factors influencing HRQoL in community-dwelling older adults in South Korea. This was a secondary analysis of a cross-sectional survey study of 735 older adults. HRQoL was measured using the EuroQoL-5 Dimension, and social frailty was measured using five items. The differences in HRQoL according to sociodemographic characteristics, health-related characteristics, and social frailty of subjects were tested using the Mann–Whitney test, Kruskal–Wallis test, and χ2 test. A Tobit regression model was used to identify the influencing factor of HRQoL. About 31.0% of the older adults were in a social pre-frailty state, and 48.4% were in a social frailty state. Of the five components of social frailty, going out less compared to the previous year and being alone were frequently observed. Older adults who had social frailty had lower HRQoL scores than those who were robust after controlling for sociodemographic and health-related characteristics (BT = −0.04, p < 0.001). Researchers need to consider older adults’ social frailty as well as health status and sociodemographic status in future interventions to improve the HRQoL of older adults.

ABSTRACT

Flats/houses in the COVID-19 pandemic era became the central place for living, working, learning, studying and entertainment. According to Maslow’s pyramid, all the basic needs had to be satisfied within a single space, which caused a change in the importance of certain locational and physical features of the flat/house. This study aimed to investigate how the COVID-19 pandemic changed the perception of the environmental features and the physical features of flats/houses. The research material was obtained from a questionnaire study disseminated through different online channels. The study was conducted in Poland, and citizens’ preferences are linked to the prevailing spatial and socio-economic determinants. A group of respondents were presented with 23 features describing the location and 17 features describing the physical features of flats/houses. They were also asked questions about the level of satisfaction with the current location and housing features. The results were analysed, and the statistical significance of the difference in the perception of the location features and the physical features of the flat/house was verified using a Chi-squared test. The results demonstrated a change in the importance of certain attributes concerning both external and internal factors. The physical features of the flat/house appeared to be more important (from the respondents’ perspective) than the features related to the location, as most changes occurred in that group. The respondents indicated that access to medical care facilities had gained importance (+8%), while good access to public transport had declined (−9%). For the physical features of flats/houses, respondents from other countries also indicated the importance of other attributes, i.e., the floor area (+12%), number of rooms (+14%), additional rooms (+14%), and access to broadband Internet and digital platforms (+28%). The study showed that over 30% of respondents would change their flats/houses if their financial means permitted.

ABSTRACT

Infectious diseases such as COVID-19 have some risk factors. One of the most important factors is the environment. This research focused on risk factors concerning the house environment. This study aimed to evaluate the parameters of the 'healthy house' environment in controlling the spread of COVID-19. This study used environmental quality, namely ventilation, humidity, brightness, temperature, and personal space area as house environment parameters. The location of the study is Coblong District, Bandung City. The χ2 test of independence was used to show the significance between environmental parameters required for the healthy house and disease transmission. The study found that one house environment parameter (ventilation) are significantly related to indoor transmission rate in recovered patients' houses (p = 0.021). Pearson correlation coefficient r was also investigated for each element of environment factor on the indoor transmission rate. Ventilation was found to be the most significant parameter correlated with indoor transmission (r = –0.522, p = 0.002). Personal Space Area also observed to have a significant correlation with indoor transmission rate (r = 0.459, p = 0.008). Humidity, brightness, and temperature were observed to have no significant correlation with indoor transmission rate (p = 0.309, 0.735, and 0.953, respectively. Linear regression is used to further investigate and predict the indoor transmission rate with significant environmental parameter as predictor. The linear regression model showed that 27.3% of indoor transmission rate variability are caused by its relationship with ventilation, the predictor used in the model.

ABSTRACT

With the sudden outbreak of COVID-19 pandemic all over the world, the education sector has experienced a tremendous transformation from its tradition way of providing lectures to the online mode of lectures. The online meeting platforms play a significant role in enhancing the online learning experience of the students. There are many online meeting platforms available, which offer several similar features yet provide different experiences to the users. It is important to evaluate the most preferable online meeting platform for the education sector to improve the overall education quality especially in the online learning era. This study, therefore, evaluates the preference of higher education students' preferences for online meeting platforms. For this study, three most commonly used online platforms i.e., Google Meet, MS Teams, and Zoom are considered. The evaluation process is done using cross-tabulation analysis and Chi-Square analysis. The results obtained in this study suggests that Google Meet is the most preferred online meeting platform by the students. This study provides an insight about the platform that can be used by the educators to improve the overall learning experiences of the students. © 2021 IEEE.

ABSTRACT

The current pandemic crisis has led to a paradigm shift in the economy. Expressions such as digital transformation and digitalization of business are common in the communication channels of economic entities, which want to benefit from the advantages of information technology (artificial intelligence, software robots, and blockchain) to streamline their business. The aim of this research is to highlight the impact of the digitalization of accounting on the business environment, the work style, and the role of professional accountants: the paradigm shift. The study is based on theoretical research as well as empirical research based on a questionnaire applied in economic entities, and respondents are both decision makers and professional accountants. The results obtained by the statistical analysis of the questionnaire (Chi-square, Crosstabulation, Friedman test) suggest that digitization is more than a conventional change, being equally about technology and people. The orientation towards digitalization implies, in addition to a well-organized implementation plan, a change in the mentalities of the human factor corroborated with the evolution of the organizational culture of economic entities. At the same time, we are witnessing a change in the accounting paradigm, and the role of professional accountants is evolving from “transaction logger” to analyst and consultant for entrepreneurs. Research confirms that the digitalization of accounting is proving to be not only a modern solution, imposed by technological progress, but also timely, necessary, and even mandatory given the difficulty of anticipating the economic and social context due to the pandemic crisis. This study stands out both because of the innovative character of the approached subject, the digitalization of accounting, which represents a concept in full expansion, and because of its practical utility. This is proven by the analyses performed and the conclusions drawn in the context of an economic environment that is constantly looking for solutions. All operations can be moved to a controlled and accessible digital environment that can be accessed from any location.

ABSTRACT

The objective of the research was to validate an instrument designed to measure the variables value perception, purchase intention, trust, and satisfaction of Micro, Small and Medium Enterprises (MSMEs) dedicated to selling clothing. The PERVAINCONSA Scale (acrostic formed with the initial letters of the Spanish words “Percepción de Valor”, “Intención de Compra”, “Confianza” and “Satisfacción”) was constructed. A total of 238 questionnaires were collected from users of online clothing stores in Peru, Mexico, and Colombia (38.7% men and 61.3% women) with an average age of 24.29 years (SD = 8.04). The KMO and Barlett’s test was 0.958. Confirmatory factor analysis provided an excellent model (χ2 = 372.76, gl = 164;χ2/df = 2.27;CFI = 0.956;RMSEA = 0.073, SRMR = 0.035;and Pclose = 0.00). The model showed good scale reliability given that the composite reliability index (CFI), and all values exceeded the minimum threshold of 0.6. The results suggest that this first version of the PERVAINCONSA presents adequate psychometric evidence to measure value perception, purchase intention, trust and satisfaction in consumers of online stores in Peru, Mexico and Colombia. Thus, it seeks to contribute to the advancement of the scientific study of these important variables in the study of consumer behavior in Latin America.

ABSTRACT

:Objective To study the kinetics of IgM and IgG antibodies based on nucleocapsid(N) and spike(S) protein of SARS-Co V2-in COVID-19 patients. Methods Immunofluorescent kits were used to detect N and S protein specific IgM and IgG antibodies from Jan.21 to Feb.11, 2020 for the 60 hospitalized COVID-19 patients(48 mild, 12 severe cases) with a total of 290 plasma samples collected 9 weeks after the onset of the disease. Results The level of antibodies specific for S protein varied significantly with the course of disease(Ig M from 27.32 to 110.10 TU/ml, IgG from 56.85 to 135.00 TU/ml), but not for N protein.Higher level of Ig M/Ig G antibodies specific to S protein was observed during the 2-7 week than that to N protein.The seropositive rate of antibodies gradually increased during the early stage of disease.IgM/IgG antibodies specific to N protein changed from 12.50% at the first week to peak level(51.72% and 86.21% respectively) at the 4 th week and those for S protein from 25.00% and 14.58% to 100.00%, and then declined.The seropositive rate of Ig M antibody specific to S protein was higher than that for N protein during 2-8 th week and that for Ig G antibody at 2, 3, 4, 6 and 7 th week.The seropositive rate of Ig G antibody specific to N protein in severe patients at the third week was higher than that in mild patients(100.00% vs 59.52%,χ2=9.67, P=0.001 9), and the same as to Ig G antibody for S protein at the second week after disease onset(80.00% vs 46.58%, χ2=5.57, P=0.018 2). Conclusions SARS-Co V2-S protein can induc stronger antibody response than N protein, and the antibody level was related to the severity of the disease.

ABSTRACT

Electric vehicles (EVs) are gradually addressing the environmental problem in cities created by internal combustion vehicles. However, to be widely used, a major challenge will still have to be tackled. Some significant challenges are the resistance to new technologies and EVs’ purchase cost, which is significantly higher than that of internal combustion vehicles. These challenges are similar to the adoption of EVs for public transportation, such as buses and taxis. Thus, this paper proposes valuable insights into attitudes and preferences for taxi and bus users for the willingness to travel in EVs, by performing a convenience sampling, focusing especially on young users. Moreover, this study highlights the possibility of the users paying additional fees to travel in electric taxis (ETs) or electric buses (EBs). Pearson’s chi-squared analysis was also performed to validate the hypotheses.
