The Environmental Kuznets Curve in a Public Spending Model of Economic Growth

Ibrahima Amadou Diallo 중앙대학교 경제연구소 2019 Journal of Economic Development Vol.44 No.4

This paper theoretically analyzes the dynamics of economic growth and the environmental Kuznets curve. This curve states an inverse U-relationship between pollution and income. The presented model specifically shows how a dynamic environmental Kuznets curve can emerge by introducing pollution and abatement technology in a public spending model of endogenous economic growth. We also derive the turning point in function of the parameters of the model. The numerical section demonstrates that when taxes are below some threshold, the turning point decreases with taxes but it increases when taxes are above the threshold point given some explanations about an N-shaped Kuznets curve. Additionally, the simulations demonstrate that taxes reduce the level of pollution by pulling down the environmental Kuznets curve. Lastly the numerical exercises highlight that the pollution level of the social planner problem is less than that of the representative agent.

Ferdinand Nyankoue Mebouinz,Amadou Kasse,Mouhamadou Habib Sy 대한견주관절의학회 2020 대한견주관절의학회지 Vol.23 No.3

Background: Resection of the radial head is a surgical indication for comminuted radial head fracture in which internal fixation is inaccessible. Some complications from the surgery can alter the function of the patient’s elbow. The objective of this study was to assess functional outcome of the elbow after resection of the radial head. Methods: A retrospective longitudinal study was performed with patients who underwent radial head resection between 2008 and 2018. Elbow function was assessed by the Mayo Elbow Performance Index (MEPI) for 11 patients comprising three women and eight men. The mean follow-up was 47.6 months. The mean age was 41±10.3 years. Results: Nine patients had a stable and painless elbow. The mean extension-flexion arc was 97.73°±16.03°. The mean values of pronation and supination were 76.8° and 74.5°, respectively. The mean MEPI score was 83.2 points, and restoration of overall function was achieved in 81% of the cases. Poor function was noted in one in 10 that presented with a terrible triad. Conclusions: Resection of the radial head restored elbow functionality at a rate of 81%, which was a good outcome for patients.

Prevalence and determinants of self-reported high blood pressure among women of reproductive age in Benin: a population-based study

Ekholuenetale Michael,Barrow Amadou 대한고혈압학회 2020 Clinical Hypertension Vol.26 No.4

Background: Addressing chronic diseases is a challenge for healthcare systems worldwide, which have largely developed to deal with acute episodic care, rather than to provide organized care for people with age-long conditions. Therefore, exploring the prevalence and identifying the risk factors is a major approach to prevention and control of chronic diseases. The aim of this study was to examine the prevalence and factors associated with self-reported high blood pressure among women of reproductive age in Benin. Methods: We utilized population-based cross-sectional data from Benin Demographic and Health Survey (BDHS). BDHS 2017–18 is the round V of the survey. A total of 7712 women of reproductive age were included in this study. The outcome variable was self-reported high blood pressure. Percentages, chi-square test and multivariable logistic regression model were used to analyze the data. Results from the multivariable logistic model were presented as adjusted odds ratio (aOR) and confidence interval (95%CI). The significance level was set at p < 0.05. Results: The total prevalence of self-reported high blood pressure among women of reproductive age in The Gambia was about one-tenth (9.9%). Furthermore, geographical region was associated with high blood pressure. Women aged 45–49 years had increased odds of high blood pressure, when compared with women aged 15–19 years (aOR = 2.73; 95%CI: 1.10, 6.79). In addition, increased maternal enlightenment gave higher odds of high blood pressure, when compared to women with low maternal enlightenment (aOR = 1.41; 95%CI: 1.08, 1.84). Women with highest neighbourhood socioeconomic disadvantaged status (poor women) had 30% reduction in the odds of high blood pressure, when compared with women of low neighbourhood socioeconomic disadvantaged status (aOR = 0.70; 0.50, 0.99). Women having increased lifetime number of sex partners (total of 3 lifetime number of sex partners: aOR = 1.40; 95%CI: 1.01, 1.94; more than 3 total lifetime number of sex partners: aOR = 1.53; 95%CI: 1.01, 2.32) were more likely to have high blood pressure, when compared to women with only one lifetime number of sex partner. Conclusions: Emphasis on high blood pressure prevention methods and involvement of multiple sectors could help to disseminate health care interventions widely. Also, a concerted effort from the stakeholders in health care system and decision-makers is needed to address the drivers of high blood pressure while maintaining health system improvement strategies. The findings could prompt appropriate policy responses towards improving the knowledge and control of high blood pressure in Benin.

The Antioxidant Effect of Plums and Polyphenolic Compounds Against H2O2-Induced Oxidative Stress in Mouse Blood Granulocytes

Jaouad Bouayed,Hassan Rammal,Amadou Dicko,Chafique Younos,Rachid Soulimani 한국식품영양과학회 2009 Journal of medicinal food Vol.12 No.4

Epidemiological and scientific research has contributed to the identification of the key role of dietary antioxidants in maintaining human health by preventing oxidative damage to cellular components. The antiradical activity of seven varieties of plums and their protective effects against oxidative stress were comparatively evaluated in mouse granulocytes in this study using a 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) test and a cellular test. The class of phytochemical compounds responsible for the main antioxidant capacities observed was also investigated. The ABTS and cellular tests revealed that the total antioxidant capacities, expressed as vitamin C equivalents, ranged from 691.2 to 2,164.64mg and from 613.98 to 2,137.59mg per 100g of fresh weight, respectively, suggesting that plums are rich in natural antioxidants and appreciably protect granulocytes from oxidative stress. Our results showed a linear correlation between either total phenolic or flavonoid contents and total antioxidant capacity, revealing that these compounds contribute significantly to the antioxidant activity of plums. The major polyphenolics in plums, identified and quantified using reversed-phase high-performance liquid chromatography, were tested to evaluate their protective effect on peripheral blood granulocytes from oxidative stress. The results suggest that individual polyphenolics contribute directly to the total protective effect of plums.

Donkey in China is well known for its draft purpose and transportation; however, donkey meat has attracted more and more consumers in recent years, yet it lacks sufficient information on its flavor components compared to other main meats. Therefore, in this study, volatile flavor compounds in neck meat of donkey, swine, bovine, and sheep were classified by electronic nose, then confirmed and quantified by gas chromatography-mass spectrometry. High-performance liquid chromatography (HPLC) and gas chromatography were used to quantify free fatty acid, amino acid, and flavor nucleotide. A total of 73 volatile compounds were identified, and aldehydes were identified as the characteristic flavor compounds in neck meat of donkey, bovine, swine and sheep in proportion of 76.39%, 46.62%, 31.64%, and 35.83%, respectively. Particularly, hexanal was the most abundant volatile flavor. Compared with other neck meat, much higher unsaturated free fatty acids were present in donkeys. Furthermore, neck meat of donkeys showed essential amino acid with highest content. Thus, special flavor and nutrition in donkey neck meat make it probably a candidate for consumers in other regions besides Asia.

Cocoa Production Output Response to Smallholder Price Speculation: Case Study of Cote d’Ivoire and Nigeria

Coulibaly Kigbajah Salifou,Cao Erbao,Amadou Maiga Ousseini,T. Metuge Mekongcho 한국국제경제학회 2019 International Economic Journal Vol.33 No.2

The paper attempts to analyze the variation in cocoa output response to international price fluctuations in two major cocoa producing countries: Cote d’Ivoire and Nigeria. The study employs a Nerlovian price expectation technique as in Ogundari (2015), and a Panel VAR model to empirically estimate changes in cocoa output using time series and an unbalanced panel dataset covering a period from 1967 to 2009. The findings indicate and in accordance with economic theory of demand and supply, that cocoa output is an inverse function of the expected prices of competing agricultural commodities like green coffee. When there is an expected price increase of cocoa, cocoa output rises. Simultaneously, if the anticipated price of coffee rises, through a cocoa–coffee substitution mechanism, smallholder farmers shift their focus to coffee production leading to a fall in cocoa output. A Granger causality test was utilized to investigate causality between cocoa output, and cocoa and coffee prices. In the case of Cote d’Ivoire, while there is only a correlation between cocoa output and price, in the case of Nigeria there was none. In addition, the study shows no unidirectional or bidirectional causality between the intervening variables and cocoa output.
