Over the past decades, environmental quality-related issues have occupied a central place in the global discourse with greater concerns to the risk of civil war, terrorism/political violence, civil disorders, and corruption which alter economic sustenance and social structures in the world. This study presents and analyses an empirical model of economic and social issues related to environmental quality within the context of the environment Kuznets curve (EKC) in Nigeria between 1990 and 2016. The empirical results based on the standard ARDL model show that increases in internal conflict and corruption are environmentally deteriorative while increases in renewable energy consumption are found to be a major driver behind environmental quality improvement. The results also show that economic growth stimulates environmental degradation and hence validates the EKC hypothesis in Nigeria. These results are robust across the estimates of the dynamic ARDL simulations with deviation only in the responses ofshocks to internal conflict and corruption which significantly dampen environmental degradation in the short run––and the predicted values remain large over the long run. Furthermore, a unidirectional causal relationship flows from economic growth to ecological footprint, renewable energy, and corruption. Also, renewable energy has a predictive power for ecological footprint. In addition, internal conflict predicts renewable energy, while a change in internal conflict is caused by corruption. These findings, therefore, provide insightful policy implications for stimulating the consumption of renewable energy as a tool for sustainable cleaner environment.

Geopolitical risks have been widely linked to oil price movements in the past. Our study as an addition to this debate shows that geopolitical threats particularly play a significant role in the volatility experienced in global oil markets with attendant policy suggestions. In this study, we employed the newly developed geopolitical threats index to examine whether threats of war, terrorism, and ethnic and political violence within and between countries are powerful enough to predict volatility in global oil prices. Monthly data on global geopolitical threats index and global prices of crude were drawn upon for causality between the periods 1990:01 and 2020:04. To this effect, two volatility indices were constructed using the deviations of Brent and WTI prices from their Hodrick-Prescott filters. The ability of the geopolitical threats index to predict volatilities was examined through a battery of causality methodologies—Granger causality test in frequency domain, nonparametric test for nonlinear causality, leveraged bootstrap causality test, and Fourier Toda-Yamamoto causality test. Through various causality methodologies, we were able to ensure robustness against various problems associated with the classical linear Granger causality testing approach and ascertain that geopolitical threats are powerful and useful predictors of volatility in global oil prices.

Traumatic brain injury (TBI) is a neurological disorder which represents a major health issue worldwide. It causes mortality and disability among all group ages, caused by external force, sports-related events or violence and road traffic accidents. In the USA, approximately one-third people die annually due to injury and 1.7 million people suffer from traumatic brain injury. Every year in India around 1.6 million individuals suffer from sustain brain injury with 200,000 deaths and approximately one million person needed recovery treatment at any stage of time. Sports-related head impact and trauma has become an extremely controversial public health and medico-legal problem that accounts for 20% of all brain injury (including concussion). It is difficult to reverse the primary injury but the secondary injury can be minimized by using proper pharmacological intervention during the initial hours of injury. This article highlights the pathophysiology and types of TBI along with treatment therapies. Till date, there is no single medication that can decrease the progression of the disease so that symptomatic treatment is given to the patient by determining proper pathology. Recently various herbal medicine therapies and traditional supplements have been developed for TBI. Nutritional supplementation and nutraceuticals have exposed potential in the treatment of TBI when used before and after TBI. The compiled data will enable the readers to know the pathophysiology as well as the allopathic and natural remedies to treat the TBI.

To identify level of job satisfaction among physicians at secondary and tertiary care levels. Random sample of 450 secondary and 523 tertiary care physicians filled in structured questionnaire about job satisfaction. Among secondary care physicians, 37.4% had extra work compared with 16.1% of tertiary care workers. More than 87% of both groups reported exposure to work-related violence. Physicians reported somewhat satisfaction for general work condition, promotion and financial aspects, work activities, and total satisfaction score with significant differences between studied groups. Significantly higher tertiary care physicians reported satisfaction with relationship in work and supervision at work compared with secondary care workers. Job satisfaction was significantly affected by age in years, number of shifts per month, years of experience, gender, being single or ever married, and having extra work. There is moderate level of satisfaction with significant differences in relation to level of care.

Little is monitored on perceived neighborhood noise, quality of drinking water, air quality, rubbish, traffic, etc. at a continental scale. This study was aimed to examine the relationships of such neighborhood risks and mental health in adults and the very old in an international and population-based setting across Europe. Data were retrieved from the European Quality of Life Survey, 2007–2012 including demographics, living conditions, income and financial situation, housing and local environment, family, work, health, social participation and quality of social services. Adults aged 18 and above were included for statistical analysis (n = 79,270). Analysis included chi-square test, t test and logistic regression modeling. People who lived in town or city tended to indicate certain major problems for them such as noise (odds ratio (OR) 2.34, 95 % confidence interval (CI) 2.17–2.53, P < 0.001), air quality (OR 2.76, 95 % CI 2.54–3.00, P < 0.001), low quality of drinking water (OR 1.33, 95 % CI 1.23–1.43, P < 0.001), crime and/or violence (OR 2.92, 95 % CI 2.68–3.19, P < 0.001), rubbish (OR 3.68, 95 % CI 3.41–3.97, P < 0.001) and traffic congestion (OR 2.64, 95 % CI 2.45–2.85, P < 0.001). People who reported major problems on noise (OR 2.19, 95 % CI 1.96–2.45, P < 0.001), air quality (OR 2.11, 95 % CI 1.87–2.37, P < 0.001), low quality of drinking water (OR 2.40, 95 % CI 2.14–2.68, P < 0.001), crime and/or violence (OR 2.13, 95 % CI 1.88–2.41, P < 0.001), rubbish (OR 1.98, 95 % CI 1.77–2.11, P < 0.001) and traffic congestion (OR 1.50, 95 % CI 1.34–1.68, P < 0.001) were also classified as having depression. Perceived neighborhood conditions were associated with adult mental health across Europe. Future neighborhood monitoring research moving from the etiological to neighborhood management would be suggested.
