Background: This work investigated attitudes and public perception regarding the impact of allowing women to drive on social, environmental, and economic aspects of the sustainable development in the Kingdom of Saudi Arabia (KSA). The study includes the perspectives of both women and men towards the potential implications of this decree on society in general and women’s well-being in particular. Methods: The methodology consisted of an online survey that was conducted before and after the decree was activated in 2017, where 62,065 individuals participated from thirteen provinces of the KSA. Geographic information systems (GISs) and statistical methods were applied to the obtained datasets to examine the geographical distribution and modeling of the effect of women driving on sustainable development of the KSA. Results: The results show that the attitudes towards allowing women to drive are geographically and statistically diverse. The study revealed that the economic impact of women driving was the highest significance, especially in increasing employment opportunities for women and decreasing household travel expenses for women. Conclusion: Overall, 70.4% of respondents agreed that women driving will positively affect the sustainable development of the KSA in terms of social and economic impact. The study also revealed that geographic location is one of the dominating factors on the attitudes towards the social impact of women driving within 95% confidence interval. Additionally, participants strongly believe (with an agreement rate of 85.1%) that Saudi women driving will improve economic development and the female job market.

Plasma cells (PCs) are the main antibody-producing cells in humans. They are long-lived so that specific antibodies against either pathogens or vaccines are produced for decades. PC longevity is attributed to specific areas within the bone marrow micro-environment, the so-called ‘niche’, providing the cells with required growth and survival factors. With antigen encounters, e.g. infection or vaccination, new PCs are generated and home to the bone marrow where they compete with resident PCs for the niche. We propose a parametrized mathematical model describing healthy PC dynamics in the bone marrow. The model accounts for competition for the niche between newly produced PCs owing to vaccination and resident PCs. Mathematical analysis and numerical simulations of the model allow explanation of the recovery of PC homoeostasis after a vaccine-induced perturbation, and the fraction of vaccine-specific PCs inside the niche. The model enables quantification of the niche-related dynamics of PCs, i.e. the duration of PC transition into the niche and the impact of different rates for PC transitions into and out of the niche on the observed cell dynamics. Ultimately, it provides a potential basis for further investigations in health and disease.

An attempt to model the human hair industry in the post-COVID-19 pandemic situation using mathematical modelling has been the goal of this article. Here we introduce a novel mathematical modelling using a system of ordinary differential equations to model the human hair industry as well as the human hair waste management and related job opportunities. The growth of human hair in the months of nationwide total lockdown has been taken into account and graphs have been plotted to analyze the effect of Lockdown in this model. The alternative employment opportunities that can be created for collecting excessive hair in the post-pandemic period has been discussed. A probable useful mathematical model and mechanism to utilize the migrant labours who became jobless due to the pandemic situation and the corresponding inevitable lockdown situation resulting out of that crisis has been discussed in this paper. We discussed the stability analysis of the proposed model and obtained the criteria for an optimal profit of the said model. Graphs have also been plotted to analyze the impact of the control parameter on the optimal profit.

PurposeThis study explored the impact of COVID-19 on the petroleum sector in Egypt, both economically and socially. Of all sectors of the economy, the oil industry has been one of the most negatively impacted by the pandemic, with oil prices plummeting at the start of the pandemic. Use to decrease demand. This paper aimed to analyse the main economic and social effects of the pandemic on the Egypt oil industry through an examination of the macroeconomic data reflected in the Egyptian balance of payments, the country's general budget and the oil industry's performance data. The study also conducted a survey of a set of workers from the Egyptian petroleum sector. The study thus concluded two levels of analysis; a macrolevel and a micro level analysis of the effect of COVID-19 on the Egyptian oil industry.Design/methodology/approachThe paper builds upon the experience gained from evaluating market change caused by COVID-19 (Agosta et al., 2020), to analyse the socioeconomic implications of COVID-19 on the Egyptian oil industry. This study employed a survey analysis of questionnaires filled by on a sample of workers in the petroleum sector in Egypt. Data were analysed using the SPSS software, version 18.0. Descriptive analysis was reported as frequencies and percentages. The macroeconomic impact analysis was done by analysing macro-economic data pertaining the oil industry's levels of production as well as the data pertaining to Egypt's external balance of payment and public finance.FindingsThe paper concludes that although the COVID-19 pandemic had negatively impacted the socioeconomics of oil sector workers, reducing their incomes and costing them jobs, these effects appeared to be short term effects that could be minimised with the end of the pandemic and be mitigated through the adequate social and economic policies. No permanent socioeconomic losses were thus deemed to be a serious concern with respect to these workers. The study also concluded that, macroeconomically, lower global oil prices has had a net positive effect on the Egyptian economy as the causing an expected shrinkage of the overall trade deficit. It also has reduced the national budget deficit and has helped mobilise money into the economy, financing both investments and social expenses.Research limitations/implicationsThe survey was very hard to reach, where lot of workers in the petroleum sector (governmental) refused to answer the questions.Practical implicationsSome African countries may not have all the necessary most recent data of economic indicators needed to ascertain with certainty the economic impact of the COVID-19 pandemic. And, at the event that data are completely available, analysts must consider that any worsening of the economy may not stem directly from the pandemic itself. Causality has to be clearly established. The survey therefore focused on the attitudes and perceptions of oil sector workers, irrespective of whether a given indicator had been affected by the pandemic or is seen likely to be affected by it in the future. All those responding have reported the belief that economic indicators, such as GDP growth, inflation and trade had been impacted negatively by the spread of COVID-19. They also believed the effects of the pandemic on transport to have had direct effects on the oil industry.Social implicationsThe social impact of the pandemic was less apparent, particularly among governmental sector workers compared with those in the private sector. However, freelancers have reported some issues that may be become more apparent through aggregated data.Originality/valueThis study has presented some preliminary estimates of the impact of the COVID-19 outbreak on petroleum sector in Egypt. The goal was not to be definitive about the virus outbreak, but rather to provide information about a range of possible economic costs of the disease. While, a detailed quantification of the socioeconomic impact of the coronavirus pandemic may not be feasible, it is still useful to identify possible transmission channels through which the pandemic may affect the Egypt economy and society. It is also useful to identify key issues that are likely shape short- and medium-term socioeconomic prospects in Egypt as a result of the COVID-19 pandemic outbreak in Egypt.

Objective To examine the impact and cost associated with mental illness. Methods A rapid review of the literature from Australia, New Zealand, UK and Canada was undertaken. The review included literature pertaining to the cost-of-illness and impact of mental illness as well as any modelling studies. Included studies were categorised according to impact on education, labour force engagement, earlier retirement or welfare dependency. The well-accepted Drummond 10-point economic appraisal checklist was used to assess the quality of the studies. Results A total of 45 methodologically diverse studies were included. The studies highlight the significant burden mental illness places on all facets of society, including individuals, families, workplaces and the wider economy. Mental illness results in a greater chance of leaving school early, a lower probability of gaining full-time employment and a reduced quality of life. Research from Canada suggests that the total economic costs associated with mental illness will increase six-fold over the next 30 years with costs likely to exceed A$2.8 trillion (based on 2015 Australian dollars). Conclusions Mental illness is associated with a high economic burden. Further research is required to develop a better understanding of the trajectory and burden of mental illness so that resources can be directed towards cost-effective interventions. What is known about the topic? Although mental illness continues to be one of the leading contributors to the burden of disease, there is limited information on the economic impact that mental illness imposes on individuals, families, workplaces and the wider economy. What does this paper add? This review provides a summary of the economic impact and cost of mental illness. The included literature highlights the significant burden mental illness places on individuals, families, workplaces, society and the economy in general. The review identified several areas for improvement. For example, only limited information is available on the impact of attention deficit hyperactivity disorder, anxiety, cognitive function, conduct disorder, eating disorder and psychological distress. There was also a dearth of evidence on the intangible elements of pain and suffering of people and their families with depressive disorders. More research is required to better understand the full extent of the impact of mental illness and strategies that may be implemented to minimise this harm. What are the implications for practitioners? Knowing the current and future impact of mental illness highlights the imperative to develop an effective policy response.

This chapter examines the economic impact of the migrants' return to Kerala, India during the Gulf oil crisis 2014-2016. Many migrants returned to their homeland during the crisis because they could not find work in the Middle East. The Kerala economy confronted this as one of the biggest threats which directly affected the economy. Almost USD 900 million had been brought to the homeland as remittance from Non-Residential Keralites (NRKs) working in Gulf countries. But the return of a large number of NRKs decreased the remittances to 10-15%. This chapter proposes Social Impact Sukuk to support the migrants who are back to their homelands from GCC countries. Data and information are collected from primary and secondary sources. This study provides policy implications for Kerala state government to examine the impact of returning NRKs issue and a feasible solution for their immediate rehabilitation.
