RESUMO

Sustainable development aims to both alleviate poverty and protect the environment. Previous research has explored the connection between poverty and carbon emissions. However, in Sub-Saharan Africa, nearly half of the population lives below the international poverty line, hindering economic growth and sustainable development. Therefore, this current study aims to further explore different age groupings of poverty and economic growth relates to environmental pollution, in 43 Sub-Saharan African nations. This study addresses existing gaps by employing the Driscoll-Kraay (D-K) standard error technique and the method of moments quantile regression to examine the connections between variables, yielding significant findings. The results indicate that youth and middle age poverty has an inverse relationship with environmental pollution. In conclusion, this study emphasizes the critical importance of addressing poverty in the formulation of policies aimed at mitigating environmental pollution and promoting sustainable development in Sub-Saharan African countries. Insights from this research can inform policymakers and other stakeholders in designing more effective interventions, programs, and initiatives to combat both poverty and environmental degradation, ultimately leading to a better and more equitable environment.

RESUMO

Clean fuels and technology-based energy is an essential source to achieve sustainable economic growth and development. Therefore, the relationship between all types of poverty and other socioeconomic indicators has been studied extensively; nevertheless, clean fuels and technology-based energy poverty, adjusted for carbon emissions, has not been studied. The current study examines the impact of clean fuels and technology-based energy poverty on carbon emissions (Co2e). Using System-Generalized Method of Movement (SGMM) estimators, this study utilized panel data from eighteen developing countries in Asia from 2006 to 2017. The empirical findings obtained from econometric model suggest the presence of clean fuels and technology-based energy poverty and its curse on environment, i.e., energy poverty positively affects Co2e growth in Asian developing countries. Furthermore, economic growth (GDP), trade, and population are also positively associated with Co2e growth and negatively affect environmental quality. Based on the empirical findings of the current study, we recommend robust policy implications that the governments of targeted countries should invest more to increase clean fuels and technologies.

RESUMO

The discussion concerning whether and how economic complexity (ECI) affects ecological footprint (EFP) has gained researchers' consideration, while there are slight empirical evidence to support the subject matter. In the support of theoretical argument, this study provides empirical evidence by investigating the impact of ECI on EFP along with the role of disaggregated energy consumptions by using a panel dataset of G-7 economies between 1996 and 2019. To this end, we applied panel techniques of Fully-Modify OLS and Dynamic-OLS models for cointegration analysis. The results obtained from Fully-Modify OLS and Dynamic-OLS models reveal that ECI deteriorates environmental quality by increasing EFP, while renewable energy reduces ecological pollution by decreasing EFP. In addition, the increasing demand for non-renewable energy and economic growth both degrades environmental quality in G-7 countries. More interestingly, the non-linear (ECI2) relationship between ECI and EFP confirms a U-shaped association (EKC hypothesis), which suggests that after achieving a certain threshold level, economic complexity mitigates environmental degradation in G-7 economies. The empirical results also suggest that other control variables such as population growth, inflation rate, foreign direct investment, and total trade intensity lead to environmental degradation by increasing ecological footprint. Based on empirical results, the following important policy implications are drawn; first, G-7 economies should speed up the level of economic complexity along with renewable energy consumption to protect environmental quality and maintain sustainable growth and development. Secondly, the governments of G-7 countries should introduce greener technologies and promote production that are environmental friendly for drastic reduction in environmental unsustainability.

RESUMO

The reduction of income inequality and environmental vulnerability is the most important factor, through which we can achieve the target of Sustainable Development Goals (SDGs). The past papers have investigated the nexus between income inequality and carbon emissions; however, the relationship between income inequality and carbon emissions along with ecological footprint has not been studied in the case of developing countries. To this end, this study analyzed the impact of income inequality on both carbon emissions and ecological footprint as well as the impact of carbon emission and ecological footprint on income inequality by using the dataset from 2006 to 2017 for the 18 Asian developing economies. This study confirmed the positive relationship between carbon emissions, ecological footprint, and income inequality under the methodology of Driscoll and Kraay (D&K) standard error approach. Specifically, a higher-income gap is destructive for environmental degradation, whereas increasing level of carbon emissions and ecological footprint also leads to rising income inequality in the investigated region. Furthermore, foreign direct investment (FDI), easy access to electricity, and population growth control income inequality, but they have a detrimental effect on both ecological footprint and carbon emissions. The empirical findings also provide some important policy implications.

RESUMO

Based on the nationally representative sample data from the Chinese General Social Survey (CGSS-2015), this study examines the relationship of education levels and health status with an individual's probability of being employed in China. The findings obtained from the binary logistic regression estimator suggest that people with a higher level of education were more likely to be employed than those who have less or no education. The individual with university or above education was found to be 85% more likely to be employed than college or equal diploma holders. Further, the healthier individual was found to be 11% more likely to be employed than relatively less healthy. Moreover, the resulting coefficients obtained from the moderation effect suggest that all of the two-way interaction effects among health status and education levels with gender are not statistically significant even at the 10% level. The results suggest that there was no multiplicative effect of gender with health status and level of education on an individual's probability of being employed. Further, the study also suggests important policy implications in the light of China's active labor force market and the gender gap in employment.

RESUMO

Normal mammalian secondary palate development undergoes a series of processes, including palatal shelf (PS) growth, elevation, adhesion and fusion, and palatal bone formation. It has been estimated that more than 90% of isolated cleft palate is caused by defects associated with the elevation process. However, because of the rapidly completed elevation process, the entire process of elevation will never be easy to clarify. In this article, we present a novel method for three-dimensional (3D) reconstruction of thick tissue blocks from two-dimensional (2D) histological sections. We established multiplanar sections of the palate and tongue in coronal and sagittal directions, and further performed 3D reconstruction to observe the morphological interaction and connection between the two components prior to and during elevation. The method completes an imaging system for simultaneous morphological analysis of thick tissue samples using both synthetic and real data. The new method will provide a comprehensive picture of reorientation morphology and gene expression pattern during the palatal elevation process.

RESUMO

Objective Bushen-Qingxin decoction combined conjugated estrogen tablets of modulation perimenopausal women osteoporosis patients, explore the impact of bone mineral density and bone metabolic markers. Methods A total of 160 female patients were recruited in our hospital by the random number table method, and were divided into the control group 80 cases and the observation group 80 cases. The control group was treated with standard dose of conjugated estrogen tablets, while the observation group was treated with Bushen Qingxin decoction on the basis of the control group. Both groups were treated 3 period with 28 days per period. The enzyme-linked immunity analyzer was used to detect serum bone-specific alkaline phosphatase (BALP), C-terminal cross linked peptide (CTX-Ⅰ), tartrate resistant acid phosphatase -5b (TRACP-5b) level, and the dual-energy X-ray absorptiometry measurement method was used to detect bone mineral density values. The clinical curative effect was compared between two groups. Results The total effective rate of the observation group was 91.3%, while the control group was 78.8%, which showed the difference was statistically significant (χ 2=3.971, P=3.971). After treatment, the serum BALP levels (88.55 ± 10.33 U/L vs. 80.47 ± 8.67 U/L, t=5.399) of the observation group were significantly higher than this of the control group (P<0.01). After treatment, the serum TRACP-5b (501.31 ± 35.77 pg/L vs. 538.51 ± 37.69 pg/L, t=6.498), CTX- (130.09 ±Ⅰ17.55 ng/ml vs. 164.71 ± 19.45 ng/ml, t=11.928) of the observation group were significantly lower than those of the control group (P<0.01). After treatment, the bone mineral density of the observation group rose up from the baseline (t=3.396, P=0.010). Conclusions The Bushen-Qingxin decoction combined conjugated estrogen tablets can increase on women in the menopausal transition of osteoporosis in patients with bone mineral density values and serum BALP levels, reduce serum TRACP-5b, CTX-Ⅰ level.

RESUMO

Objective To evaluate the differences among five representative and useful Doppler parameters in the diagnosis of the three common types of renal artery stenosis (RAS). Methods Five Doppler parameters including renal peak systolic velocity (RPSV), renal-aortic ratio (RAR), renal-interlobar ratio (RIR),acceleration time (AT),and resistant index (RI) were measured in 221 patients before renal arteriography. Differences between the groups of patients with various clinical causes of RAS were analyzed by Chi-Squared test. One-way ANOVA or t test were used to compare the means between different groups.The optimal cutoff value was determined with the maximum sum of sensitivity and specificity. Results Of the 442 renal arteries (main and accessory renal arteries) demonstrated at arteriography,214 were normal or stenosed less than 50 %, 204 stenoses 50% - 99 %, and 24 occlusions. RIR, RAR and RI were significantly different between the atherosclerotic and non-atherosclerotic RAS groups (P <0.05), while RPSV and AT were not. The optimal cutoff values of RAR,RIR and RI for detecting RAS between the atherosclerotic and non-atherosclerotic groups were much different (2.5 versus 1.9, 5. 1 versus 6.5, 0.57 versus 0.50,respectively) ,but those of RPSV and AT were similar or the same (170 cm/s versus 200 cm/s,51 ms versus 51 ms,respectively). Conclusions In the case of RAS (diameter reduction≥50%),it is advised to establish separate cutoff values of RAR, RIR and RI according to atherosclerotic and non-atherosclerotic RAS, but the same cutoff value of RPSV and AT can be applied. RIR is a good Doppler parameter in the diagnosis of RAS,especially atherosclerotic and fibromuscular dysplasia RAS.
