The forming of the Xiakou basin was attributed to the pull-apart fault depression by the above fractures in earlier Cretaceous, afterward, series deposits such as Guantou formation （K1g）, Chaochuan formation （K1c） and Fangyan formation （K1f） which belong to Yongkang group, the lower Cretaceous layer accumulated in the Xiakou basin. In late Cretaceous, the above fractures occurred to extrude and the basin began to uplift, meanwhile, amounts of tension fissures and joints were produced since Cenozoic, which accelerated water-dicing into bed-rock. Consequently, landform-building processing： weathering, eroding and collapsing etc. were prevalent as finally to develop the so-called Danxia landform. The Jianglang Mountain landscape zone of the Danxia landform to apply for world natural relics are relying on unique and unparalleled peak, sky-split valley with vivid stones and reviving of platform. What is more, there is significance of study at lithology, stratigraphy and paleo-biology. According to dating for specimen of ophitic vein through-crossing the Yongkang group of Yafeng Peak by K-Ar method, this article revealed the uplift age of red-bed basin to be 77.89±2.6 MaBP （K2） i.e. late Cretaceous, and it is the first chronological datum of Danxia landform research in China.展开更多

Their spatial combinations reflect that the developments of Danxia landform have undergone stages of geomorphic cyclical erosion in the form of weathering, collapse, transportation, sedimentation and other processes, together with the "sculpture" of external forces mainly as tectonic uplift. The picturesque Danxia landform began its formation at that point. Danxia landform developed mainly in the strata of Fangyan Formation (K1f) caused by the alluvial fan-braided river phase of anterior fan in the late period of the Early Cretaceous. Regular patterns of weathering of stones and features of braided alluvial phase sediments may be verified by the analysis of three groups of experimental data. Danxia landform of Fangyan is a unique representative of the "adolescent" development type in the application of the World Natural Heritages status in China, by virtue of its outstanding universal aesthetic and scientific value.展开更多

Conditions for pitchfork, Hopf, Takens-Bogdanov, and codimension-two bifurcations are presented. The Lorenz model is used to study the inverted bifurcation. Positive values of the Soret coefficient favor a pitchfork bifurcation, whereas negative values favor a Hopf bifurcation. Takens-Bogdanov and codimension-two bifurcations are not as much influenced by the Soret coefficient as pitchfork and Hopf bifurcations. The influence of the Soret coefficient on the inverted bifurcation is similar to the influence on the pitchfork bifurcation. The in- fluence of other parameters on the aforementioned bifurcations is also similar as reported earlier in the literature. Using the Newell-Whitehead-Segel equation, the condition for occurrence of Eckhaus and zigzag secondary instabilities is obtained. The domain of ap- pearance of Eckhaus and zigzag instabilities expands due to the presence of the Soret coefficient for positive values. The Soret coefficient with negative values enhances heat transport, while positive values diminish it in comparison with heat transport for the case without the Soret effect. The dual nature of other parameters in influencing heat and mass transport is shown by considering positive and negative values of the Soret coefficient.展开更多

Given the disastrous outbreak of COVID-19 second wave in India, the health system of country was virtually at the brink of collapse. Therefore, to identify the factors that resulted into breakdown and the challenges, Indian healthcare system faced during the second wave of COVID-19 pandemic, this paper analysed the health system challenges in India and the way forward in accordance with the six building blocks of world health organization (WHO). Applying integrated review approach, we found that the factors such as poor infrastructure, inadequate financing, lack of transparency and poor healthcare management resulted into the overstretching of healthcare system in India. Although health system in India faced these challenges from the very beginning, but early lessons from first wave should have been capitalized to avert the much deeper crisis in the second wave of the pandemic. To sum-up given the likely future challenges of pandemic, while healthcare should be prioritized with adequate financing, strong capacity-building measures and integration of public and private sectors in India. Likewise fiscal stimulus, risk assessment, data availability and building of human resources chain are other key factors to be strengthened for mitigating the future healthcare crisis in country.展开更多

The mathematical analysis is performed in the presence of viscous dissipation, Joule heating, and a first-order chemical reaction. With suitable transformations, the governing partial differential equations through momentum, energy, and concentration laws are transformed into ordinary differential equations. The resulting equations are solved by the homotopy analysis method （HAM）. The convergence of the series solutions is ensured. The effects of the emerging parameters, the skin friction coefficient, the Nusselt number, and the Sherwood number are analyzed on the dimensionless velocities, temperature, and concentration fields.展开更多

Atmospheric input of nutrient is believed to exceed that of river discharge due to relatively higher contribution of water mass to the Lake from atmosphere. However, precipitation characteristics with respect to nutrients have not been well studied to allow qualification and quantification of atmospheric contribution to the Lake Victoria. This study was conducted to investigate influence of land use activities on spatial and temporal variation of nutrient inputs from atmosphere and to estimate atmospheric loading to the Lake Victoria. The results revealed that there is significant spatial and temporal variation of nutrient deposition in the study area. High concentrations of nutrients were observed during short rains starting from September to December. This was attributed to dissolution of nutrients from soil particals and ash residues due to biomass burning accumulated in the atmosphere during dry season of June to August. Spatial variation of nutrients reflects land use activities. Urban and peri-urban areas showed very high concentration of nitrate nitrogen due to industrial and vehicle emission while rural area showed high concentration of phosphorous species and reduced forms of nitrogen species reflecting agricultural activities and animal keeping. Generally, nutrient deposition load was higher in rural area compared to urban with respective values of 15.5 and 13.9 kg·haˉ1·yˉ1 for total nitrogen and 6.1 and 2.8 kg·haˉ1·yˉ1 for total phosphorous. These results suggest that in order to realize significant reduction of nutrient input to the Lake Victoria, measures should be taken to control agricultural activities through proper land use planning. The measure may be directed to reduce biomass burning, emission from industries and vehicle as well as animal residue.展开更多

Methods: A total of 78 patients with severe craniocerebral injury who underwent emergency treatment in Huanggang Central Hospital between September 2015 and May 2017 were selected as the research subjects and divided into control group (n=39) and mild hypothermia group (n=39) by random number table. Control group received clinical standard large trauma craniotomy for severe craniocerebral injury, and mild hypothermia group received routine surgery and postoperative mild hypothermia therapy. The cerebral oxygen metabolism and brain injury in two groups of patients were detected immediately after admission (T0), 1 week after treatment (T1) and 4 weeks after treatment (T2). Results: At T0, there was no statistically significant difference in the levels of cerebral oxygen metabolism indexes, cerebral blood flow parameters and brain injury markers between the two groups. At T1 and T2, PO2 levels in mild hypothermia group were higher than those in control group while Da-jvO2 levels were lower than those in control group;cerebral blood flow parameters Vs and Wv levels were higher than those in control group while PI levels were lower than those in control group;brain injury markers MBP, AQP-4 and S-100B contents were lower than those in control group while BDNF contents were higher than those in control group. Conclusion: Adjuvant mild hypothermia therapy after routine surgery may further reduce the cerebral oxygen metabolism and relieve the brain injury in patients with severe craniocerebral injury.展开更多

METHODS： Electronic database searches were con- ducted in the Chinese National Knowledge Infra- structure and VlP, and the Western databases, Pubmed, the National Science and Technology Li- brary, and the German Journal of Acupuncture, from 1990 to April, 2012. We also searched the doc- uments of international symposiums for auricular acupuncture points （AAPs）. Keywords were ＂auricu- lar points＂, ＂auricular acupuncture points＂, ＂ear points＂, or ＂auriculotherapy＂ RESULTS： Basic and clinical research on AAPs was performed in China, the United States, France, andGermany. Clinical AAP research was done in Italy, Austria, Switzerland, Spain, the UK, Holland, Japan, Russia, and Africa. However, AAP research was not communicated internationally. The World Federa- tion of Acupuncture-Moxibustion Societies recom- mended international standard of auricular acu- puncture points （ISAAPs）. Standardized nomencla- ture and locations of AAPs would provide a solid basis to draft an international standard organiza- tion. CONCLUSION： Experts need to find common points from different countries or regions, provide evidence of different ideas, and list the proposal as a recommendation for an international standard.展开更多

文摘Essex-Lopresti injury is characterized by a radial head fracture accompanied by dislocation of the distal radioulnar joint and rupture of the interosseous membrane(IOM).This type of injury typically results from high-energy axial forces transmitted through the wrist to the elbow,leading to tears in the IOM,fractures of the radial head,injuries to the distal radioulnar joint,and disruption of the triangular fibrocartilage complex,ultimately causing axial instability of the radioulnar joint.Due to its complexity,this injury is often overlooked in clinical settings,with a reported misdiagnosis rate as high as 60%.In pediatric cases,the misdiagnosis rate is even higher due to children's limited ability to articulate symptoms,the presence of substantial cartilaginous structures that have not fully ossified,and less typical radiographic findings compared to adults.This review aims to provide a comprehensive overview of the injury mechanism,clinical presentation,diagnosis,and treatment of Essex-Lopresti injuries in children,emphasizing the importance for pediatric orthopedists to recognize and manage this condition accurately to prevent misdiagnosis and inappropriate treatment.

文摘BACKGROUND Lenvatinib has become an indispensable part of treatment regimens for patients with advanced hepatocellular carcinoma(aHCC).Several recent real-world studies appear to have confirmed this;however,there are etiological differences.This necessitates further real-world studies of lenvatinib across diverse populations,such as in China.AIM To investigate the efficacy and safety of lenvatinib in a Chinese HCC patient population under real-world conditions.METHODS This is a retrospective and multiregional study involving patients with aHCC receiving lenvatinib monotherapy.Efficacy was assessed using the Response Evaluation Criteria in Solid Tumors version 1.1.Baseline characteristics and adverse events(AEs)were recorded throughout the entire study.RESULTS In total,54 HCC patients treated with lenvatinib monotherapy were included for final analysis.The objective response rate was 22%(n=12)with a progressionfree survival(PFS)of 168 d;however,AEs occurred in 92.8%of patients.Multivariate analysis showed that the Barcelona Clinic Liver Cancer stage[hazard ratio(HR)0.465;95%CI:0.23-0.93;P=0.031],portal vein tumor thrombus(HR 0.38;95%CI:0.15-0.94;P=0.037)and Child-Pugh classifications(HR 0.468;95%CI:and specificity(83.3%)of decreasing serum biomarkers including alphafetoprotein were calculated in order to predict tumor size reduction.Gene sequencing also provided insights into potential gene mutation signatures related to the effect of lenvatinib.CONCLUSION Our findings confirm previous evidence from the phase III REFLECT study.The majority of patients in this Chinese sample were suffering from concomitant hepatitis B virus-related HCC.However,further analysis suggested that baseline characteristics,changes in serum biomarkers and gene sequencing may hold the key for predicting lenvatinib responses.Further large-scale prospective studies that incorporate more basic medical science measures should be conducted.

文摘Jianglang Mountain is situated at the transitional zone of South China fold-system, Jiangshan-Shaoxing deep fracture zone and Baoan-Xiakou-Zhangcun fracture zone. The forming of the Xiakou basin was attributed to the pull-apart fault depression by the above fractures in earlier Cretaceous, afterward, series deposits such as Guantou formation （K1g）, Chaochuan formation （K1c） and Fangyan formation （K1f） which belong to Yongkang group, the lower Cretaceous layer accumulated in the Xiakou basin. In late Cretaceous, the above fractures occurred to extrude and the basin began to uplift, meanwhile, amounts of tension fissures and joints were produced since Cenozoic, which accelerated water-dicing into bed-rock. Consequently, landform-building processing： weathering, eroding and collapsing etc. were prevalent as finally to develop the so-called Danxia landform. The Jianglang Mountain landscape zone of the Danxia landform to apply for world natural relics are relying on unique and unparalleled peak, sky-split valley with vivid stones and reviving of platform. What is more, there is significance of study at lithology, stratigraphy and paleo-biology. According to dating for specimen of ophitic vein through-crossing the Yongkang group of Yafeng Peak by K-Ar method, this article revealed the uplift age of red-bed basin to be 77.89±2.6 MaBP （K2） i.e. late Cretaceous, and it is the first chronological datum of Danxia landform research in China.

文摘The prominent types of Danxia landform in Fangyan include enclosed valleys, mesas, peaks, stone columns and grooves etc. Their spatial combinations have regular configurations along the northwest–southeast direction: typical grooves and caves are located in the northwestern Wufengshuyuan mainly; abundant fresh collapsed stones may be observed in central Jimingfeng and Taohuafeng; stone drums and stone columns are in the southeastern Shiguliao particularly; enclosed valleys are encircling joints of peaks and plains from three directions east, west, and south. Their spatial combinations reflect that the developments of Danxia landform have undergone stages of geomorphic cyclical erosion in the form of weathering, collapse, transportation, sedimentation and other processes, together with the "sculpture" of external forces mainly as tectonic uplift. The picturesque Danxia landform began its formation at that point. Danxia landform developed mainly in the strata of Fangyan Formation (K1f) caused by the alluvial fan-braided river phase of anterior fan in the late period of the Early Cretaceous. Regular patterns of weathering of stones and features of braided alluvial phase sediments may be verified by the analysis of three groups of experimental data. Danxia landform of Fangyan is a unique representative of the "adolescent" development type in the application of the World Natural Heritages status in China, by virtue of its outstanding universal aesthetic and scientific value.

文摘Linear and weakly nonlinear analyses are made for the Rayleigh-Benard convection in two-component couple-stress liquids with the Soret effect. Conditions for pitchfork, Hopf, Takens-Bogdanov, and codimension-two bifurcations are presented. The Lorenz model is used to study the inverted bifurcation. Positive values of the Soret coefficient favor a pitchfork bifurcation, whereas negative values favor a Hopf bifurcation. Takens-Bogdanov and codimension-two bifurcations are not as much influenced by the Soret coefficient as pitchfork and Hopf bifurcations. The influence of the Soret coefficient on the inverted bifurcation is similar to the influence on the pitchfork bifurcation. The in- fluence of other parameters on the aforementioned bifurcations is also similar as reported earlier in the literature. Using the Newell-Whitehead-Segel equation, the condition for occurrence of Eckhaus and zigzag secondary instabilities is obtained. The domain of ap- pearance of Eckhaus and zigzag instabilities expands due to the presence of the Soret coefficient for positive values. The Soret coefficient with negative values enhances heat transport, while positive values diminish it in comparison with heat transport for the case without the Soret effect. The dual nature of other parameters in influencing heat and mass transport is shown by considering positive and negative values of the Soret coefficient.
文摘The unprecedented healthcare demand due to sudden outbreak of coronavirus disease 2019 (COVID-19) pandemic has almost collapsed the health care systems especially in the developing world. Given the disastrous outbreak of COVID-19 second wave in India, the health system of country was virtually at the brink of collapse. Therefore, to identify the factors that resulted into breakdown and the challenges, Indian healthcare system faced during the second wave of COVID-19 pandemic, this paper analysed the health system challenges in India and the way forward in accordance with the six building blocks of world health organization (WHO). Applying integrated review approach, we found that the factors such as poor infrastructure, inadequate financing, lack of transparency and poor healthcare management resulted into the overstretching of healthcare system in India. Although health system in India faced these challenges from the very beginning, but early lessons from first wave should have been capitalized to avert the much deeper crisis in the second wave of the pandemic. To sum-up given the likely future challenges of pandemic, while healthcare should be prioritized with adequate financing, strong capacity-building measures and integration of public and private sectors in India. Likewise fiscal stimulus, risk assessment, data availability and building of human resources chain are other key factors to be strengthened for mitigating the future healthcare crisis in country.

文摘The aim of this paper is two-dimensional magnetohydrodynamic viscous fluid bounded by infinite sheets to examine the Dufour and Soret effects on the （MHD） steady flow of an electrically conducting An incompressible viscous fluid fills the porous space. The mathematical analysis is performed in the presence of viscous dissipation, Joule heating, and a first-order chemical reaction. With suitable transformations, the governing partial differential equations through momentum, energy, and concentration laws are transformed into ordinary differential equations. The resulting equations are solved by the homotopy analysis method （HAM）. The convergence of the series solutions is ensured. The effects of the emerging parameters, the skin friction coefficient, the Nusselt number, and the Sherwood number are analyzed on the dimensionless velocities, temperature, and concentration fields.
文摘This study examines the impact of financial development on corporate investment in terms of their influence on financing constraints.This study also tries to find the effect of financial development on the investment-cash flow sensitivity across the size,degree of financial constraints and group affiliation of the firm.This study employs dynamic panel data model or more specifically system generalized method of moments(GMM)estimation technique.The estimation results reveal that cash flow affects the investment decision of the company positively,which implies that Indian firms are financially constrained.Also,we observe that financial development reduces the investment-cash flow sensitivity and the effect of financial development is more prominent for small size and standalone firms.The results are robust across the period and,for both financially constrained and unconstrained firms.This study contributes to the existing literature by analyzing the impact of financial development on the role of cash flow in determining investments undertaken by the Indian firms,which is an unexplored issue from an emerging market perspective.
文摘Increase in population growth and the associated activities have increased the nutrient input to the Lake Victoria through atmosphere and river discharge. Atmospheric input of nutrient is believed to exceed that of river discharge due to relatively higher contribution of water mass to the Lake from atmosphere. However, precipitation characteristics with respect to nutrients have not been well studied to allow qualification and quantification of atmospheric contribution to the Lake Victoria. This study was conducted to investigate influence of land use activities on spatial and temporal variation of nutrient inputs from atmosphere and to estimate atmospheric loading to the Lake Victoria. The results revealed that there is significant spatial and temporal variation of nutrient deposition in the study area. High concentrations of nutrients were observed during short rains starting from September to December. This was attributed to dissolution of nutrients from soil particals and ash residues due to biomass burning accumulated in the atmosphere during dry season of June to August. Spatial variation of nutrients reflects land use activities. Urban and peri-urban areas showed very high concentration of nitrate nitrogen due to industrial and vehicle emission while rural area showed high concentration of phosphorous species and reduced forms of nitrogen species reflecting agricultural activities and animal keeping. Generally, nutrient deposition load was higher in rural area compared to urban with respective values of 15.5 and 13.9 kg·haˉ1·yˉ1 for total nitrogen and 6.1 and 2.8 kg·haˉ1·yˉ1 for total phosphorous. These results suggest that in order to realize significant reduction of nutrient input to the Lake Victoria, measures should be taken to control agricultural activities through proper land use planning. The measure may be directed to reduce biomass burning, emission from industries and vehicle as well as animal residue.

文摘Objective: To investigate the effects of mild hypothermia on cerebral oxygen metabolism and brain injury in patients with severe craniocerebral injury. Methods: A total of 78 patients with severe craniocerebral injury who underwent emergency treatment in Huanggang Central Hospital between September 2015 and May 2017 were selected as the research subjects and divided into control group (n=39) and mild hypothermia group (n=39) by random number table. Control group received clinical standard large trauma craniotomy for severe craniocerebral injury, and mild hypothermia group received routine surgery and postoperative mild hypothermia therapy. The cerebral oxygen metabolism and brain injury in two groups of patients were detected immediately after admission (T0), 1 week after treatment (T1) and 4 weeks after treatment (T2). Results: At T0, there was no statistically significant difference in the levels of cerebral oxygen metabolism indexes, cerebral blood flow parameters and brain injury markers between the two groups. At T1 and T2, PO2 levels in mild hypothermia group were higher than those in control group while Da-jvO2 levels were lower than those in control group;cerebral blood flow parameters Vs and Wv levels were higher than those in control group while PI levels were lower than those in control group;brain injury markers MBP, AQP-4 and S-100B contents were lower than those in control group while BDNF contents were higher than those in control group. Conclusion: Adjuvant mild hypothermia therapy after routine surgery may further reduce the cerebral oxygen metabolism and relieve the brain injury in patients with severe craniocerebral injury.
文摘The magnetohydrodynamic （MHD） flow of the third grade fluid between two permeable disks with heat transfer is investigated. The governing partial differential equa- tions are converted into the ordinary differential equations by suitable transformations. The transformed equations are solved by the homotopy analysis method （HAM）. The expressions for square residual errors are defined, and the optimal values of convergence- control parameters are selected. The dimensionless velocity and temperature fields are examined for various dimensionless parameters. The skin friction coefficient and the Nus- selt number are tabulated to analyze the effects of dimensionless parameters.
文摘The emphasis on the simplification of cognitive and motor tasks by recent results of morphological computation has rendered possible the construction of appropriate“mimetic bodies”able to render accompanied computations simpler,according to a general appeal to the“simplexity”of animal embodied cognition.A new activity of what we can call“distributed computation”holds the promise of originating a new generation of robots with better adaptability and restricted number of required control parameters.The framework of distributed computation helps us see them in a more naturalized and prudent perspective,avoiding ontological or metaphysical considerations.Despite these progresses,there are still problems regarding the epistemological limitations of computational modeling remain to be solved.

文摘One of the factors facilitating the expansion and proliferation of wild boar Sus scrofa is the plasticity of its reproductive biology.Nevertheless,the real influence of maternal and environmental factors on number and sex of the offspring is stll controversial.While the litter size was shown to be related with the maternal condition,the strength of this relation remains to be understood,together with the possible role played by environmental conditions.Analogously,it is unclear whether wild boar females can adjust their offspring sex.We investigated multiple aspects of wild boar maternal investment by means of a 10-year dataset of female reproductive traits and a set of biologically meaningful environmental variables.The maternal condition slightly affected the litter size but not the offspring sex,and environment did not affect the litter size or the offspring sex.Moreover,mothers did not cope with the higher costs entailed by producing sons by placing them in the most advantageous intrauterine position,nor by allocating less resources on daughters.Our set of results showed that the female reproductive investment is quite rigid in comparison with other aspects of wild boar reproductive biology.Wild boar females seem to adopt a typical rstrategy,producing constantly large litters and allocating resources on both sexes regardless of internal and external conditions.Such strategy may be adaptive to cope with environmental unpredictability and an intense human harvest,contributing to explain the extreme success of wild boar within human-dominated landscapes.
文摘Research on flow and heat transfer of hybrid nanofluids has gained great significance due to their efficient heat transfer capabilities.In fact,hybrid nanofluids are a novel type of fluid designed to enhance heat transfer rate and have a wide range of engineering and industrial applications.Motivated by this evolution,a theoretical analysis is performed to explore the flow and heat transport characteristics of Cu/Al_(2)O_(3) hybrid nanofluids driven by a stretching/shrinking geometry.Further,this work focuses on the physical impacts of thermal stratification as well as thermal radiation during hybrid nanofluid flow in the presence of a velocity slip mechanism.The mathematical modelling incorporates the basic conservation laws and Boussinesq approximations.This formulation gives a system of governing partial differential equations which are later reduced into ordinary differential equations via dimensionless variables.An efficient numerical solver,known as bvp4c in MATLAB,is utilized to acquire multiple(upper and lower)numerical solutions in the case of shrinking flow.The computed results are presented in the form of flow and temperature fields.The most significant findings acquired from the current study suggest that multiple solutions exist only in the case of a shrinking surface until a critical/turning point.Moreover,solutions are unavailable beyond this turning point,indicating flow separation.It is found that the fluid temperature has been impressively enhanced by a higher nanoparticle volume fraction for both solutions.On the other hand,the outcomes disclose that the wall shear stress is reduced with higher magnetic field in the case of the second solution.The simulation outcomes are in excellent agreement with earlier research,with a relative error of less than 1%.

文摘OBJECTIVE： To supply literature for developing an international standard of auricular acupuncture points. METHODS： Electronic database searches were con- ducted in the Chinese National Knowledge Infra- structure and VlP, and the Western databases, Pubmed, the National Science and Technology Li- brary, and the German Journal of Acupuncture, from 1990 to April, 2012. We also searched the doc- uments of international symposiums for auricular acupuncture points （AAPs）. Keywords were ＂auricu- lar points＂, ＂auricular acupuncture points＂, ＂ear points＂, or ＂auriculotherapy＂ RESULTS： Basic and clinical research on AAPs was performed in China, the United States, France, andGermany. Clinical AAP research was done in Italy, Austria, Switzerland, Spain, the UK, Holland, Japan, Russia, and Africa. However, AAP research was not communicated internationally. The World Federa- tion of Acupuncture-Moxibustion Societies recom- mended international standard of auricular acu- puncture points （ISAAPs）. Standardized nomencla- ture and locations of AAPs would provide a solid basis to draft an international standard organiza- tion. CONCLUSION： Experts need to find common points from different countries or regions, provide evidence of different ideas, and list the proposal as a recommendation for an international standard.
文摘Background/Objectives:Many economies are on the trajectory of alternative growth drivers other than conventional capital and labor.Access to credit facilities is a pertinent indicator of economic growth.In line with the United Nations Sustainable Development Goals(UNSDGs-8)agenda,the national goal for sustainable development for most economies and Arab economies is no exception.Therefore,the current study adopts a traditional growth model by exploring the relationship between gross domestic product(GDP)per capita,credit for private sectors,ratio of exports,real GDP,and per labor force participants for selected Arab economies annually from 2001 to 2020.Research design:This study leverages the Fourier Kwiatkowski–Phillips–Schmidt–Shin(KPSS)unit root test and second-generation panel econometrics as estimation techniques,such as Westerlund and Edgerton panel cointegration test,and the use of two estimators,namely the augmented mean group(AMG)and common correlated error mean group(CCEMG),to obtain robust results.Findings:Empirical findings from Westerlund and Edgerton panel cointegration tests validate the long-run equilibrium relationship among the outlined variables.Further empirical results indicate that the share of exports is negatively significant with economic growth in countries such as Kuwait,Lebanon,Tunisia,and Jordan.Additionally,savings and labor force participation have a positive relationship with economic growth in individual countries such as Algeria and Bahrain.As per the panel,there is no significant relationship between labor force participation and economic growth.This indicates that the skilled labor force enhanced economic growth.Conclusions:These findings come with inherent far-reaching policy suggestions for economies and panels.Further details on country-specific policy actions are presented in the concluding section.
