Global digital divide and environmental degradation in Africa.

ICTs and access to Internet use are considered vital for the achievement of sustainable development goals. So, this study explored the effect of the global digital divide, trade openness, renewable energy consumption, and forestation on greenhouse gas (GHG) emissions in 42 high-income countries (HICs) and high-middle-income (HMICs), low-income countries (LICs), and low-middle-income countries (LMICs) of Africa from 1990 to 2018. TheDumitrescu-Hurlin causality results confirmed a unidirectional causality from GHG emissions to the global digital divide (HICs and HMICs), global digital divide to GHG emissions (LICs), and GHG emission to trade openness (LICs and LMICs). Moreover, the long-run results of the autoregressive distributed lag (ARDL) model showed an increase in GHG due to an increase in the global digital divide in all three panels. Further, ARDL results showed reduced GHG emissions due to increased trade openness in LIC and LMICs, renewable energy consumption, and forestation in all three panels. Thus, to encounter pollution from Internet use, the government should start environment-friendly projects through public and private investment in smart and modern environment-friendly technology and reduce the taxes and tariffs on them. Moreover, the governments of African countries should create public awareness through print and electronic media for raising the forestation area.

Do natural disasters affect economic growth? The role of human capital, foreign direct investment, and infrastructure dynamics.

Natural disasters do occur and have become a global problem due to increasing intensity. Developing countries are mostly affected due to natural disasters owing to a poor environment, feeble adaptation, impoverished socioeconomic conditions, poor infrastructure, limited resources, and unstable institutions. The SDG 11.5 target which highlights the mitigation of loss due to natural disasters--remains crucial to achieving sustainable cities and human settlements--but the literature is limited on this scope. Thus, this research contributes to the literature by incorporating an infrastructure index, foreign direct investment (FDI), human capital index, globalization, and capital formation into the disaster-growth debate across four-income groups in 98 countries from 1995 to 2019. We developed infrastructure and human capital indices using a standard procedure across all income groups. The two-step generalized method of moments employed herein confirmed the income reduction effect of natural disasters. While the economic cost of natural disasters is relatively high in low-income countries and mild in high- and upper-middle-income countries. Besides, infrastructural development, FDI, human capital, globalization, and gross fixed capital formation also affect economic growth across income groups. Thus, the enhancement of socio-economic policies could decline economic losses, especially in vulnerable and poor settlements in developing countries.

Estimation of economic, environmental, and social efficiency for sustainable development in G-8 and SAARC countries: a data envelopment analysis.

In the recent era, economic growth is not enough to represent sustainable development. Sustainable development has three dimensions (i.e., economic, social, and environment). This study estimated the economic, social, and environmental efficiency using data from 2000 to 2021. Input-oriented data envelopment analysis shows strong heterogeneity across developed (G-8) and developing countries (SAARC). There is a potential to increase economic and environmental efficiency in the G-8 and SAARC countries. The average economic efficiencies are 0.682 and 0.414, which implies the possibility of the same output (GDP/capita) by using 31.8% and 58.6% fewer inputs in G-8 and SAARC countries, respectively. The social efficiency score is more than 0.980 in both panels. The average environmental efficiencies are 0.712 and 0.724, which implies that selected countries can obtain the same output (CO2 emission reduction) by using 28.8% and 27.6% fewer inputs in G-8 and SAARC countries, respectively. The top three economically efficient countries are (a) the USA, the UK, and Japan in the G-8 panel and (b) Maldives, Sri Lanka, and Pakistan in the SAARC panel. The top three environmentally efficient countries are (a) France, the UK, and Italy in the G-8 panel and (b) Afghanistan, Nepal, and Bangladesh in the SAARC panel. It is recommended to adopt suitable policies to reduce emission, minimize waste, efficient utilization of resources, increase forest cover, and incentive for clean technologies. It is suggested to promote renewable energy through the provision of micro-credit to the poor, subsidizing renewable energy technologies, implementation of stringent environmental policies, and increasing awareness. It is essential to invest in eco-friendly and innovative technologies; thus, the government should encourage green practices in production. Human development is recommended to increase the living standard and healthy life. The government should invest in the health system and conduct seminars on general health awareness. Investment in basic infrastructure (drinking water, sanitation, and clean fuel) is essential to increase the living standard. The G-8 countries should provide financial and technological help to the SAARC countries.

Modeling financial development, tourism, energy consumption, and environmental quality: Is there any discrepancy between developing and developed countries?

The main purpose of this study is to explore the dynamic association between financial development, tourism, primary and renewable energy utilization, urbanization, and carbon emission by employing the longitudinal data of 52 countries from 1995 to 2017. Empirical results of panel pooled mean group-autoregressive distributive lag (PMG-ARDL) model reveal that financial development significantly improves the environmental quality in developed countries. However, it has a detrimental but insignificant effect on the environment in developing countries. In the case of developed countries, the profound tourism sector is more harmful to the environment due to a large number of tourist arrivals in contrast to the developing countries. There is a wide difference between developed and developing countries concerning industrial, regional, and economic structure, in the effect of financial and tourism development on carbon emission, but both urbanization and primary energy utilization promote carbon emissions. The utilization of renewable energy sources improves the environmental quality in both regions. Generally, it is suggested that investment in renewable energy resources in both regions affects pollution differently and still has the potential to accelerate environmental quality. Moreover, the panel causality test explores that there exists bidirectional causality between financial development, primary energy, and carbon emission in both regions, while a unidirectional causality is observed from urbanization to carbon emission in developed countries. In developing countries, it exists from tourism to carbon emission and carbon emission to renewable energy. Finally, from policy perspectives, the results of this research recommend developing the financial system, and more funds should be allocated in modern and eco-friendly energy projects and utilized energy-efficient technologies.

An empirical nexus between economic growth, energy utilization, trade policy, and ecological footprint: a continent-wise comparison in upper-middle-income countries.

This study investigates the causal connection between economic growth, foreign direct investment, primary and renewable energy utilization, trade openness, and ecological footprint for 33 upper-middle-income countries (UMICs) from Africa, Asia, Europe, and America during the period from 1994 to 2017. Initially, first- as well as second-generation panel unit root tests are applied to check the integration order after confirming the cross-sectional dependency and heterogeneity. Four different tests (FMOLS, DOLS, FGLS, and AMG) are applied to estimate the long-run elasticity, whereas Dumitrescu and Hurlin (D-H) non-causality test is used to test growth, conservation, and feedback hypothesis. Results show negative relationship of economic growth on ecological footprint in Africa and Europe; renewable energy utilization in Asia, Europe, and America; and trade openness in Asia. Moreover, the results revealed an adverse impact of trade openness on ecological footprint in case of Africa and America. Furthermore, the results of D-H panel non-causality test confirm the growth hypothesis for economic growth to ecological footprint in Africa, Asia, and Europe; foreign direct investment to ecological footprint in Africa and Asia; primary energy utilization to ecological footprint in Asia; renewable energy utilization to ecological footprint in America; and trade openness to ecological footprint in Africa, Asia, and America. Furthermore, the feedback hypothesis was confirmed between economic growth and ecological footprint in Asia and Europe; foreign direct investment and ecological footprint in Africa and Asia; renewable energy utilization and ecological footprint for America; and trade openness and ecological footprint for Asia and America. Finally, in context to efficient policy implications, it is suggested to associate the economic growth with clean energy and environment-friendly technologies by expanding the share of renewable energy in America and economic growth in Africa and Europe. Furthermore, Asian policy makers need to focus on foreign direct investment and trade openness by using green energy to overcome the environmental degradation. Impulsion with these findings, the central authorities of UMICs need to focus on more investments in environmental quality not only through foreign direct investment but also exchanging their clean energy technologies through trade policies such as tax exemption, feed-in tariffs, and subsidies. Government of these countries ought to upgrade the conventional capital which will ultimately improve the human lives by providing clean environment.

Role of Methyl Prednisolone in Longitudinal Extensive Transverse Myelitis (LETM) in Children.

OBJECTIVE: The role of methyl prednisolone in longitudinal extensive transverse myelitis in children is not completely discovered in developing country like Pakistan. So this is the first study which aimed to evaluate the efficacy of methyl prednisolone in longitudinal extensive transverse myelitis in children. METHODS: This is quasi experimental hospital based descriptive prospective study. The data was collected from 34 children admitted in Paediatric Neurology department through Outpatient/emergency department in Children's Hospital and the Institute of Child Health, Lahore for period of one year from January 2018 to December 2018. The children full filling the inclusion criteria were observed before and after giving injection methyl prednisolone 30mg/kg/dose (maximum dose one Gram irrespective of the body weight) once daily for five days in the form of intravenous infusion. RESULTS: Complete recovery was seen in 41.2% while 58.8% showed partial recovery. The correlation of response to treatment (recovery) with gender, area of spinal cord involvement, muscle power and autonomic dysfunction is found at significance level of five percent according to Chi square test. CONCLUSION: Early consideration and administration of methyl prednisolone in longitudinally extensive transverse myelitis in children can be beneficial and can help to reduce the morbidity.

The impact of temperature, rainfall, and health worker density index on road traffic fatalities in Pakistan.

A road traffic accident is a burning issue because the cost of road accidents is about 2% of gross domestic product in Pakistan. This paper explores the relationship between health force density index, temperature, rainfall, road lengths, and road traffic fatalities in Pakistan from 1985 to 2016. The stationarity was determined with the help of four-unit root tests. The existence of long-run cointegration was determined by using the autoregressive distributing lag bound test. The vector error correction model showed the long-run causality of road traffic fatalities, which implies that road traffic fatalities were affected by selected variables in the long-run. The short-run unidirectional causality was running from road traffic fatalities to health force density index; temperature to health force density index; rainfall to health force density index; health force density index to rainfall; road traffic fatalities to high type road length; health force density index to high type road length; and temperature to high type roads. The reduction in road fatalities was 1.713% due to a 1% increase in health force density. But, road fatalities increase by 3.628% due to a 1% increase in temperature. The road fatalities increase by 0.255% and 0.485% due to a 1% increase in rainfall and high type road length, respectively. The governments should increase the number of doctors and nurses for the life-saving of an injured person. Due to the adverse impact of temperature on road safety, the government should formulate a comprehensive environmental policy in order to mitigate global warming. It is recommended to increase the forest area to reduce the level of emission. It is required to modify the system of transportation according to the guidelines of international transportation associations with respect to the quality and maintenance of vehicles, medical check-up of drivers, and construction of roads. Installation of speed cameras is also needed on high type roads to ensure road safety. It is also recommended to increase traffic law enforcement. It is difficult for the Pakistani government to effectively execute road safety plans due to the limitation of resources. However, the government should invest the revenue collected through tax violation fine for the improvement in road safety. It is also needed to invest in the health sector and up-gradation of the hospitals for the safety of human beings. The government should ensure the availability of the latest medical technology in the hospitals and the improvement of emergency services. It is required to develop coordination between various ministries such as transportation, planning, law, education, public health, and information. It is necessary to make the public aware of the social and economic cost of road accidents using electronic, print, and social media. Graphical abstract.

Road traffic fatalities and its determinants in high-income countries: a continent-wise comparison.

Road traffic accidents (RTAs) are accountable for 1.2 million deaths and road safety is the part of sustainable development goals, which aims to provide a safe, accessible, affordable, and sustainable transport system by 2030. This study discovered the nexus of road traffic fatalities (RTFs) with its determinants in Asia, Europe, and America. Vector error correction model established the causality of RTFs (Asia, Europe), urbanization (Asia), physicians (Asia, Europe), traffic law enforcement index (Europe, America), vehicles (America), and paved roads (America). Short-run bidirectional causality of RTFs was established with educational expenditures (Asia, Europe), GNI (Europe), and urbanization (Europe). The fall in RTFs was 0.359% (Europe) and 0.957% (America) for 1% rise in GNI. The RTFs were decreased by 0.498% (Europe) and 0.390% (America) due to 1% rise in urbanization. Education shows 0.952% reduction in RTFs in Europe. The 1% increase in the number of physicians causes 0.793% reduction in RTFs in America. The RTFs were increased by 0.617% and 1.705% for 1% rise in the number of vehicles in Asia and America. The fall in RTFs was 3.604%, 0.134%, and 0.950% for 1% rise in paved roads in Asia, Europe, and America, respectively. Results show a reduction of 0.744% (Asia), 0.712% (Europe), and 0.312% (America) in RTFs due to 1% increase in traffic law enforcement index. The governments of all countries should expand and improve their paved road network and increase the enforcement of traffic laws. The government should make strict traffic laws like regular inspection of vehicles, strict inspection for the driving license, electronic challan, and medical fitness of drivers. The government should ensure the medical checkup of drivers at subsidized rates. It is useful to include the traffic rules in the educational syllabus due to the significant role of law enforcement in road safety. The government should use different media channels for the awareness of the public about loss due to road accidents.

The dependency analysis between energy consumption, sanitation, forest area, financial development, and greenhouse gas: a continent-wise comparison of lower middle-income countries.

This study explored the long-run association among greenhouse gases (GHGs), financial development, forest area, improved sanitation, renewable energy, urbanization, and trade in 24 lower middle-income countries from Asia, Europe, Africa, and America (South and North) by using panel data from 1990 to 2015. Granger causality was tested by Toda and Yamamoto approach. The bi-directional causality was established among urbanization and GHGs (Asia), financial development and forest (Asia), energy use and renewable energy (Asia), renewable energy and forest (Asia), improved sanitation and forest (Asia, Africa, America), urbanization and forest (Asia), and improved sanitation and financial development (Europe). The GHG emission also shows one-way causality is running from financial development to GHG (America), energy to GHG (Asia), renewable energy to GHG (America), forest area to GHG (America), trade openness to GHG (Africa), urbanization to GHG (Europe), GHG to financial development (Europe), GHG to energy use (Europe, Africa, and America), and GHG to trade openness (Asia). On the basis of fully modified ordinary least square and generalized method of moment, the reciprocal relationship of GHGs was observed due to financial development in Asia and Africa; renewable energy in all panels; forest area in Asia, Europe, and America; improved sanitation in Asia, Africa, and America; trade openness in Africa; and urbanization in Europe and America. Policymakers should concentrate on these variables for the reduction in GHGs. The annual convergence towards long-run equilibrium was 50.5, 31.9, and 20.9% for America, Asia, and Africa, respectively.

General dependencies and causality analysis of road traffic fatalities in OECD countries.

The road traffic accidents were responsible for material and human loss which was equal to 2.8 to 5% of gross national product (GNP). However, literature does not explore the elasticity coefficients and nexus of road traffic fatalities with foreign direct investment, health expenditures, trade openness, mobile subscriptions, the number of researchers in R&D department, and environmental particulate matter. This study filled this research gap by exploring the nexus between road traffic fatalities, foreign direct investment, health expenditures, trade openness, mobile subscriptions, the number of researchers, and environmental particulate matter in Organization for Economic Cooperation and Development (OECD) countries by using panel data from 1995 to 2015. The panel Autoregressive Distributed Lag (ARDL) bound test was used for the detection of cointegration between the variables after checking the stationarity in selected variables with different panel unit root tests. Panel vector error correction model explored the causality of road traffic fatalities, foreign direct investment, PM2.5 in the environment, and trade openness in the long run. Road traffic fatalities showed short run bi-directional causality with foreign direct investment and health expenditures. The short run bi-directional causality was also observed between trade and foreign direct investment and cellular mobile subscriptions and foreign direct investment. The panel fully modified ordinary least square (FMOLS) and panel dynamic ordinary least square (DOLS) showed the 0.947% reduction in road fatalities for 1% increase in the health expenditures in OECD countries. The significant reduction in road fatalities was also observed due to 1% increase in trade openness and researchers in R&D, which implies the importance of trade and research for road safety. It is required to invest in the health sector for the safety of precious human lives like the hospitals with latest medical equipment and improvement in the emergency services in the country. The research and development activities should be enhanced especially for the health and transportation sectors. The trade of environment-friendly technology should be promoted for the protection of environment.

Clinical Spectrum and Outcome of Cerebral Venous Sinus Thrombosis in Children.

OBJECTIVE: To determine clinical spectrum, neuroimaging finding and outcome of cerebral venous sinus thrombosis (CVST) in children. STUDY DESIGN: Descriptive and cross-sectional study. PLACE AND DURATION OF STUDY: Department of Paediatric Neurology, Children's Hospital and Institute of Child Health, Lahore, from 2015 to 2016. METHODOLOGY: Data was collected in a predesigned proforma by non-probability purposive sampling technique from all enrolled 32 patients fulfilling the inclusion criteria. We analysed descriptively the clinical presentation, neuroimaging findings, associated risk factors and outcome. Chi-square test was used to check the association between demographic variables and findings at five percent level of significance. RESULTS: Out of 32 patients enrolled, 75% (24) patients were male; median age was 2.5 years. Fever was found the most common presentation followed by headache and lethargy. Neuroimaging showed superior sagital sinus thrombosis in all (100%), while 25% (8) have additional thrombosis of internal cerebral veins. Ischemic infarction was found in 11 (35%), while hemorrhagic infarction was found in 9 (29%) patients. Death occurred in 6.25% of children. CONCLUSION: Infections were the common cause of CVST in children followed by anemia and dehydration. Mortality trend was low with earlier diagnosis and aggressive treatment. Anticoagulant treatment along with adequate hydration, antibiotics and correction of anemia can lead to a better outcome. A large local and regional prospective multicenter studies for pediatric cerebral venous sinus thrombosis is suggested to evaluate the risk factors and plan guidelines for managing this condition in children.
