Evolving waste management: The impact of environmental technology, taxes, and carbon emissions on incineration in EU countries.

Amid the urgent global imperatives concerning climate change and resource preservation, our research delves into the critical domains of waste management and environmental sustainability within the European Union (EU), collecting data from 1990 to 2022. The Method of Moments Quantile Regression (MMQR) results reveal a resounding commitment among EU member states to diminish their reliance on incineration, which is evident through adopting green technologies and environmentally conscious taxation policies, aligning with the European Union's sustainability objectives. However, this transition presents the intricate task of harmonizing industrial emissions management with efficient waste disposal. Tailoring waste management strategies to accommodate diverse consumption patterns and unique circumstances within individual member states becomes imperative. Cointegrating regressions highlighted the long-run relationship among the selected variables, while Feasible Generalized Least Squares (FGLS) and Panel-Corrected Standard Errors (PCSE) estimates roughly confirmed MMQR results. ML analyses, conducted through two ensemble methods (Gradient Boosting, GB, and Extreme Gradient Boosting, XGBoost) shed light on the relative importance of the predictors: in particular, environmental taxation, consumption-based emissions, and production-based emissions greatly contribute to determining the variation of combustible renewables and waste. This study recommends that EU countries establish monitoring mechanisms to advance waste management and environmental sustainability through green technology adoption, enhance environmental taxation policies, and accelerate the renewable energy transition.

Exploring the relationship between financial inclusion and natural resource utilization in QUAD economies.

This study delves into the intricate relationship between financial inclusion (FIC) and economic development (ED) within the context of QUAD nations, including the USA, Australia, India, and Japan. Using panel data spanning from 2000 to 2021, the research investigates this relationship by employing various statistical techniques. Initially, the Jarque-Bera (JB) normality test highlights the non-normal distribution of the data. Furthermore, the findings reveal varying slopes and cross-sectional interdependence among the variables, while the panel unit root test confirms their non-stationarity. Consequently, the adoption of the method of moment quantile regression is deemed appropriate for the analysis. The study's results uncover a negative association between FIC and total natural resource rent (TNRR), while renewable-energy usage (REU), ED, and foreign direct investment (FDI) exhibit a positive relationship with FIC. Notably, the impact of TNRR on FIC diminishes at higher quantiles, indicating a diminishing effect. Similarly, the influence of REU and ED on FIC also decreases at higher quantiles, suggesting a reduced contribution as other sectors gain prominence. Conversely, FDI positively affects FIC, with a more pronounced impact observed at higher quantiles. Policy recommendations for QUAD nations include enhancing FIC initiatives, promoting REU, fostering balanced ED, attracting FDI, and encouraging collaborative efforts among the nations. Furthermore, it is imperative for developing nations to implement widespread financial literacy programs specifically targeting vulnerable and marginalized populations, equipping individuals with essential knowledge to make informed financial decisions and gain access to formal financial services.

The relationship between economic growth and environmental degradation: could West African countries benefit from EKC hypothesis?

There are growing concerns about environmental degradation and economic expansions in West Africa. Although there are several growth-environmental studies in Africa, there is limited empirical research exploring West African countries' potential of benefiting from the environmental Kuznets curve (EKC) hypothesis, with the few studies on this subject reporting diverse results based on selected West African countries. To fill this gap, this study explored the relationship between economic growth and environmental degradation within the EKC framework using 16 West African countries sub-grouped into low-income countries (LICs) and lower-middle-income countries (LMICs) between 1990 and 2018. This study implemented second-generation panel econometric estimators that are robust to cross-sectional dependent and parameter heterogeneity. The empirical results revealed that the data is cross-sectionally dependent, heterogeneous, integrated of order one, 1(1), and cointegrated. Controlling for other environmental determinants, panel estimates from the Augmented Meant Group and Common Correlated Effect Mean Group estimators revealed that economic growth accelerates environmental degradation in West African countries, with a greater impact on LMICs, followed by LICs in West Africa. The results also showed that West African countries especially LMICs could benefit from the EKC hypothesis. On the other hand, growth-environmental degradation among LICs in West Africa shows a monotonous increasing relationship. We found strong evidence to support for feedback hypothesis between economic growth and environmental degradation in LMICs, LICs, and West Africa as a whole. Based on the findings, policy recommendations that consider both LMICs and LICs and West Africa as a whole were offered to policymakers.

Research capacity training for graduate students in basic medical sciences with the guideline of translational medicine / 中华医学科研管理杂志

In China,few research findings in basic medicine could be translated to clinical practice,which is known as the disconnection between basic research and clinical application.Such phenomenon is mainly due to lack of ability in translational medicine,particularly,lack of training in clinical research and translational medicine.Now the emergence of translational medicine has put forward new requirements for graduate education in medical school,and demanding that the patient-centered concept be strengthened.As the major force of scientific and technological innovation,graduate students should receive long-term systematic trainings and conduct original researches.In addition,advanced courses in clinical research and translational medicine should be offered to graduate students ;furthermore,translation research platforms should be built up for them so as to improve the capacity of scientific research and innovation.

Expression of growth associated protein mRNA in nerves of splenic autograft after autotransplantation in rats / 中国组织工程研究

BACKGROUND: The patients with severe spleen rupture can save their spleen functions by auto-transplantation of the spleen tissues in the greater omentum. Whether the transplanted spleen tissues are regulated by nerves or not is still unclear. The growth associated protein, GAP-43, is a specific protein of the nervous system, and by testing the GAP-43 in the transplanted spleen tissues, nerve regeneration can be understood.OBJECTIVE: To study the mRNA expression of the GAP-43 in the regenerated spleen tissues at different phases after the auto-transplantation of the spleen tissues, and to find the regeneration regularity of the GAP-43 + nerves in the auto-transplanted spleen tissues.DESIGN: A randomized and controlled experiment SETTING: A teaching and research office of the surgical applied anatomy and operative surgery department in a university MATERIALS: The study was done in the Surgical Applied Anatomy and Operative Surgery Department of the Third Military Medical University of Chinese PLA from September 2002 to July 2003. A total of 120 Wistar mice were chosen. The mice were randomly divided into the experiment group and pseudo-operation group(control group) to make animal models. After the operation, mice of the two groups were fed under the same circumstances. The spleen tissues were respectively taken at the 15th, 30th, 60th,90th, 120th and 180th days after the operation for the study.METHODS: The general RNA was extracted from the tissues using the Tripure agent by the routine method. The general RNA was reverse transcribed into cDNA using the M-MLV reverse transcription kit. The mRNA of the GAP-43 was quantitatively measured using the gel pattern analysis.tern analysis.RESULTS: Totally 30 days after the transplantation of the spleen tissues, the mRNA of the GAP-43 was found to be expressed in the auto-transplanted spleen tissues. Ninety days after the operation, the expression reached the peak level. Totally 120 to 180 days after the operation the amount of the mRNA of the GAP-43 in the transplanted spleen tissues gradually got close to that in the normal spleen tissues.CONCLUSION: The expression of mRNA of the GAP-43 in the auto-transplanted spleen tissues suggests the regeneration of the nervous fiber in the transplanted spleen tissues.
