Purpose Corona Virus Disease 2019 (COVID-19) is a deadly virus named after severe acute respiratory syndrome coronavirus 2; it affects the respiratory system of the human and sometimes leads to death. The COVID-19 mainly attacks the person with previous lung diseases; the major cause of lung diseases is the exposure to nitrogen dioxide (NO2) for a longer duration. NO2 is a gaseous air pollutant caused as an outcome of the vehicles, industrial smoke and other combustion processes. Exposure of NO2 for long-term leads to the risk of respiratory and cardiovascular diseases and sometimes leads to fatality. This paper aims to analyze the NO2 level impact in India during pre- and post-COVID-19 lockdown. The study also examines the relationship between the fatality rate of humans because of exposure to NO2 and COVID-19. Design/methodology/approach Spatial analysis has been conducted in India based on the mortality rate caused by the COVID-19 using the data obtained through Internet of Medical things. Meanwhile, the mortality rate because of the exposure of NO2 has been conducted in India to analyze the relationship. Further, NO2 level assessment is carried out using Copernicus Sentinel-5P satellite data. Moreover, aerosol optical depth analysis has been carried out based on NASA’s Earth Observing System data. Findings The results indicate that NO2 level has dropped 20-year low because of the COVID-19 lockdown. The results also determine that the mortality rate because of long-time exposure to NO2 is higher than COVID-19 and the mortality rate because of COVID-19 may be a circumlocutory effect owing to the inhalation of NO2. Originality/value Using the proposed approach, the COVID-19 spread can be identified by knowing the air pollution in major cities. The research also identifies that COVID-19 may have an effect because of the inhalation of NO2, which can severe the COVID-19 in the human body.

Purpose – The purpose of this paper is to give a good overview of the relationship between industrial growth and industrial pollution in Turkey. The question is to what extent dirty industries have been affected by the regulations on the control of environmental degradation. Design/methodology/approach – The approach for this study uses all regulations which serve for protecting human and its environment from danger arising from dirty industries in Turkey. After presenting brief explanations on green industry, next sessions explain and compare the situations of the Turkish dirty industries and its relationship with related regulations in the European Union (EU). Findings – The authors offer three solutions. First, clean consumption should be stimulated in Turkish society. Second, Turkish Government should conduct more joint projects with the EU. Third, EU funds should be directed to cleaner production technologies to subsidize dirty industries during the negotiation process. Originality/value – Green industry can be assessed as a steep road to build a sustainable future. For a long time, the unsustainability of current forms of industrial production has been discussed in Turkey. As a solution some argue that if governments support, industries can finance their own transformation more rapidly. However, these arguments do not mean that industries voluntarily accept these changes.

✓ A series of 8814 head-injured patients admitted to 41 hospitals in three separate metropolitan areas were prospectively studied. Of these, 1906 patients (21.6%) were 14 years of age or less. This “pediatric population” was compared to the remaining “adult population” for mechanism of injury, admission Glasgow Coma Scale score, motor score, blood pressure, pupillary reactivity, the presence of associated injuries, and the presence of subdural or epidural hematoma. The relationship of each of these factors was then correlated with posttraumatic mortality. Except for patients found to have subdural hematoma and those who were profoundly hypotensive, the pediatric patients exhibited a significantly lower mortality rate compared to the adults, thus confirming this generally held view. This study indicates that age itself, even within the pediatric age range, is a major independent factor affecting the mortality rate in head-injured patients.

ABSTRACT Signal transduction systems are essential for microorganisms to respond to their ever-changing environment. They can be distinguished into one-component systems, two-component systems, and extracytoplasmic-function σ factors. Abundances of a few signal-transducing proteins, termed herein as sensory proteins (SPs), have previously been reported to be correlated with the genome size and ecological niche of certain Gram-positive bacteria. No such reports are available for Gram-negative bacteria. The current study attempts to investigate the relationship of the abundances of SPs to genome size in Escherichia coli, and the bacterial pathotypes or phylotypes. While the relationship between SP abundance and genome size could not be established, the sensory protein index (SPI), a new metric defined herein, was found to be correlated with E. coli virulence. In addition, significant association was observed among the distribution of SPs and E. coli pathotypes. Results indicate that such associations might be due to genomic rearrangements to best utilize the resources available in a given ecological niche. Overall, the study provides an in-depth analysis of the occurrence of different SPs among pathogenic and nonpathogenic E. coli strains. Possibilities of using the SPI as a marker for identifying pathogenic strains from among an organism complex are also discussed. IMPORTANCE Sensory proteins (SPs) act as sensors and actuators for a cell and participate in important mechanisms pertaining to bacterial survival, adaptation, and virulence. Therefore, bacterial species residing in similar ecological niches or those sharing common pathotypes are expected to exhibit similar SP signatures. We have investigated profiles of SPs in different species of Escherichia coli and present in this article the sensory protein index (SPI), a metric for quantifying the abundance and/or distribution of SPs across bacterial genomes, which could indicate the virulence potency of a bacterium. The SPI could find use in characterizing uncultured strains and bacterial complexes, as a biomarker for disease diagnostics, evaluating the effect of therapeutic interventions, assessing effects of ecological alterations, etc. Grouping the studied strains of E. coli on the basis of the frequency of occurrence of SPs in their genomes could potentially replicate the stratification of these strains on the basis of their phylotypes. In addition, E. coli strains belonging to the same pathotypes were also seen to share similar SP signatures. Furthermore, the SPI was seen to be an indicator of pathogenic potency of E. coli strains. The SPI metric is expected to be useful in the (pathogenic) characterization of hereto uncultured strains which are routinely sequenced in host microbiome analysis projects, or from among an ensemble of microbial organisms constituting a biospecimen. Thus, the possibilities of using the SPI as a biomarker for diagnosis of a disease or the outcome of a therapeutic intervention cannot be ruled out. Further, SPIs obtained from longitudinal ecological samples have the potential to serve as key indicators of environmental changes. Such changes in the environment are often detrimental to the resident biome and methods for timely detection of environmental changes hold huge socioeconomic benefits.

Business Ties

Purpose The purpose of this paper is to propose a new integrated model that combines the concepts of network ties (e.g. political ties and business ties), the organization of internal critical attributes (such as social capital, human capital and innovation capability) and analyses of how those critical attributes influence organization performance and competitive advantage. Design/methodology/approach A structural equation model and three-way interactions in moderated multiple regressions was used to test the hypotheses on a sample of 621 cultural and creative industry (CCI) managers in Taiwan. Findings The results indicate that human capital mediates the relationship between social capital and innovation capability. Furthermore, innovation capability also plays a mediating role in connecting the relationships between human capital, competitive advantage and organizational performance. The findings indicate that business ties strengthen the relationship between social and human capital. The level of human capital is at its peak when social capital, business ties, and political ties considerably interact with one another. Research limitations/implications The present study conceptualized the topic and systematized the questionnaire design and data collection, statistical analysis, and report writing. This study performs a systematic analysis to present the research but does not employ in-depth qualitative interviews to analyse the essential attributes of the different entrepreneurial styles. In-depth interviews enable the interviewees to completely depict their feelings, experiences, motivations, emotions and attitudes. Thus, this method can provide an in-depth analysis. Studies can be conducted to analyse the complexity of the processes involved. Practical implications This study determines and emphasizes that networking with various factors to create innovation is the key to enhancing competitive advantage and organizational performance. Innovation is a unique characteristic and a basic kinetic energy that affects various strategic organizational behaviours that positively influence competitive advantage and facilitate organizational performance. Hence, CCI firms need to consider market orientation and innovation in this highly competitive environment. Originality/value To the best of the knowledge, how CCI firms use networking sources to create competitive advantage and organizational performance, thereby promoting the development of the CCIs of Taiwan, has not been analysed in the tourism-related literature. Thus, the present study provides a significant contribution to the human capital literature, in which empirical research analyses the three-way interaction and demonstrates the empirical insights that may be used to study human capital. The findings reported in this study will encourage future researchers to employ multilevel human capital perspectives.

Purpose This study aims to investigate the influence of employee positions (supervisor vs line-level employee) on work-related variables (e.g. work engagement, job satisfaction and turnover intentions). Design/methodology/approach Data were collected from line-level employees and supervisors of 29 mid- to up-scale hotels. A series of one-way ANCOVA were performed to test the position differences in work engagement, job satisfaction and turnover intentions. Hierarchical regression analyses were conducted to examine the moderating role of employees’ positions on the relationships between those variables. Findings Supervisors have significantly higher work engagement and lower turnover intentions than line-level employees, whereas job satisfaction does not differ across positions. Employee positions significantly moderate the relationship between absorption and job satisfaction, and the relationship between dedication and turnover intentions. Practical implications This study provides an in-depth analysis for hotel managers to capture work-related factors (i.e. work engagement, job satisfaction and turnover intentions) across employee positions. Dedication is the primary barometer that significantly leads to job satisfaction and reduced turnover intentions compared to vigor and absorption. Although job satisfaction may be boosted by improving employee work engagement (i.e. vigor, dedication and absorption), increasing absorption is not an effective solution to increase supervisors’ job satisfaction. Hotel managers need to carefully monitor supervisors’ levels of dedication, given its focal impact on turnover intentions. Originality/value This study is one of the first attempts to examine the differences between line-level employees’ and supervisors’ work engagement (i.e. vigor, dedication and absorption) and its consequences (i.e. job satisfaction and turnover intentions). Findings highlight the unique influence of the individual dimension of work engagement on job satisfaction and turnover intentions. This study reveals the moderating effect of employee positions on the links between engagement dimensions and consequences.

Test Result

Purpose The detection of an adversary in secret image sharing has been a problematic side in the reconstruction phase. Some of verifiable secret sharing solutions have been proposed to solve the problem. However, there is some computational limitation in the previous schemes. The purpose of this paper is to analyze the importance of consistency for detecting an adversary in a secure reconstruction phase. Strong t-consistency assures the correctness of reconstructed secret as long as participants P ∈ N and n(P) = t. Consistency is a solution for preventing the participant to be absent and helps the dealer to easily detect the adversary without an additional verification step. Design/methodology/approach This paper focuses on secure reconstruction, and uses two different approaches, namely, single-secret and multi-secret, to experiment the relationship between the given variable (t,m,n) and the adversaries by observing the quality test result, polynomial approach and visualization. Findings The results show that t and m are inversely proportional to the image quality without respect to the polynomial approach. The reconstruction phase is declared as securely conducted when m = 2t − 1, for both single- and multi-secret approaches. Originality/value The application of consistency is a considerable step for securing the secret from an adversary by combining the reconstruction phase and the consistency combination at once, removing the need for additional separate verification steps for decreasing the computational time, especially in secret image sharing.

Purpose This paper aims to examine the effect of development aid volatility on foreign direct investment (FDI) volatility in aid recipient countries. Design/methodology/approach The empirical analysis has relied on a sample of 117 countries over the period 1981–2016 and used the two-step system generalized methods of moments (GMM) approach. Findings The findings indicate that development aid volatility exerts a positive and significant effect on FDI volatility, with the magnitude of this positive effect rising as countries’ real per capita income increases. Furthermore, development aid volatility is non-linearly related to FDI volatility, as additional rises in the degree of development aid volatility further amplify FDI volatility. Research limitations/implications These outcomes highlight that volatility of development aid inflows enhances the volatility of FDI inflows. Thus, the enhancement of the aid coordination system between donor-countries and recipient-countries would not only help mitigate the volatility of aid – which reduces the macroeconomic effectiveness of aid – but also stabilizes FDI inflows to developing countries. Practical implications A limitation of the present paper is its reliance on aggregate FDI inflows to perform the analysis. Availability of data on greenfield FDI inflows and cross-border mergers and acquisitions FDI inflows over a long-time-period would provide an opportunity to conduct an in-depth analysis of the volatility of development aid on FDI inflows volatility. Furthermore, it could be interesting to investigate in the future (if data is available) the extent to which aid coordination systems between donor-countries and recipient-countries versus recipient-countries’ domestic factors contribute to explaining the dynamics of FDI inflows volatility in recipient-countries of these two types of capital flows. Originality/value To the best of the authors’ knowledge, this topic has not been addressed in the literature.

Purpose – The purpose of this paper is to explore the relationship between the ratification of the United Nations’ (UN’s) Convention on the Elimination of All Forms of Discrimination against Women (CEDAW) and women’s and girls’ health outcomes using a unique longitudinal data set of 192 UN-member countries that encompasses the years from 1980 to 2011. Design/methodology/approach – The authors focus on the impact of CEDAW ratification, number of reports submitted after ratification, years passed since ratification, and the dynamic impact of CEDAW ratification by utilizing ordinary least squares (OLS) and panel fixed effects methods. The study investigates the following women’s and girls’ health outcomes: total fertility rate, adolescent fertility rate, infant mortality rate, maternal mortality ratio, neonatal mortality rate, female life expectancy at birth (FLEB), and female to male life expectancy at birth. Findings – The OLS and panel country and year fixed effects models provide evidence that the impact of CEDAW ratification on women’s and girls’ health outcomes varies by global regions. While the authors find no significant gains in health outcomes in European and North-American countries, the countries in the Northern Africa, sub-Saharan Africa, Southern Africa, Caribbean and Central America, South America, Middle-East, Eastern Asia, and Oceania regions experienced the biggest gains from CEDAW ratification, exhibiting reductions in total fertility, adolescent fertility, infant mortality, maternal mortality, and neonatal mortality while also showing improvements in FLEB. The results provide evidence that both early commitment to CEDAW as measured by the total number of years of engagement after the UN’s 1980 ratification and the timely submission of mandatory CEDAW reports have positive impacts on women’ and girls’ health outcomes. Several sensitivity tests confirm the robustness of main findings. Originality/value – This study is the first comprehensive attempt to explore the multifaceted relationships between CEDAW ratification and female health outcomes. The study significantly expands on the methods of earlier research and presents novel methods and findings on the relationship between CEDAW ratification and women’s health outcomes. The findings suggest that the impact of CEDAW ratification significantly depends on the country’s region. Furthermore, stronger engagement with CEDAW (as indicated by the total number of years following country ratification) and the submission of the required CEDAW reports (as outlined in the Convention’s guidelines) have positive impacts on women’s and girls’ health outcomes.

Purpose This paper aims to investigate the relationship between relational capital produced by universities and knowledge structures, which include both the capacities and competencies that students have learned and the capabilities they have put into practice. Design/methodology/approach To analyse research data and test the proposed model, partial least squares structural equation modelling (SmartPLS 3.2.9) is used on a sample of 125 students of a Spanish university. Findings The results of the study demonstrate that the creation of relational capital by universities will depend largely on how students’ capacity is supplemented and merged with students’ competency to develop synergies that increase the students’ capability to give an additional value to the community members. Originality/value This study allows an in-depth analysis of the cause and effect link between the knowledge structures and support the members of higher educational institutions to understand how to achieve relational capital in universities.

Purpose This study aims to examine psychological mechanisms underlying tacit knowledge-sharing behaviours. The personality trait of conscientiousness is tested in relation to knowledge sharing, and the effect of eagerness and subjective norm on the intention to share is measured in the context of local and multinational knowledge-intensive enterprises in Croatia. Design/methodology/approach The quantitative study was conducted on a sample of 288 employees of small and medium-sized companies working on knowledge-intensive tasks. The purposive sampling technique and a survey strategy were used in the study. Organizational affiliation, as it was presumed that these individuals possess a higher degree of tacit knowledge. The data collection was conducted in October 2019. Respondents worked in science and technology companies in Croatia on assignments involving information technology, electronics, petrochemicals, medicine and biochemistry. Statistical product and service solutions analysis of a moment structures software was used to perform confirmatory factor analysis and structural equation modelling. Findings The findings suggest that the personality trait of conscientiousness has a positive impact on tacit knowledge sharing behaviour. An attitude of eagerness and subjective norm were also confirmed as predictors of tacit knowledge sharing behaviour. Furthermore, conscientiousness influences the eagerness to share knowledge. A significant association between subjective norm and conscientiousness was also established. Finally, the mediating effects were identified, indicating that subjective norm and eagerness mediate the relationship between conscientiousness and tacit knowledge sharing. Practical implications Explaining the relationship between personality and attitude in the context of knowledge sharing will result in a better understanding of factors that should be nurtured within individuals. Accordingly, distinct management initiatives are to be developed to suit these factors. Furthermore, to intensify the knowledge exchange when working on knowledge-intensive tasks of significant economic value, organizations tailor a more particularistic application to suit the individual in the domain of leadership, staffing decisions, work organization and incentive systems. Originality/value This study provides an in-depth analysis and theoretical understanding of factors salient for knowledge-sharing behaviour. The authors provide an overview of how knowledge sharing evolves during social interaction through intensive problem-solving sessions and teamwork. The authors render the explanation on how the personality trait of conscientiousness, conjoint with the attitude of eagerness to share know-how in the expert surrounding, is conducive to the generation of tacit knowledge sharing. Underpinning this study are employees’ psychological motives and internal drives to communicate individual cognitive capital outweighing the potential negative consequences, such as losing the competitive advantage over the colleagues.
