Effect of the production site on stable isotopes of ethanol in fruit spirits

Stable isotope ratio analyzes are powerful analytical methods that can be used to check the authenticity of alcoholic beverages and to detect any adulteration. The Forensic Institute of National Tax and Customs Administration applies stable isotope techniques - SNIF-NMR (Site specific Natural Isotope Fractionation), IRMS (Isotope Ratio Mass Spectrometry) to determine the botanical origin of the alcoholic beverages. The process starting from fruit until the Hungarian ‘pálinka’ has several steps, most of them well studied: fermentation from fruit sugar to ethanol, sample preparation (Cadiot distillation) and isotopic measurements (SNIF-NMR, IRMS). To keep the complete process under control only the study of the isotope fractionation effect of distillation step during the production procedure is missing. In this study the control of the different scale fermentation and distillation step was investigated by comparing isotope ratios: (D/H), δ13C of ethanol distilled from spirits produced in laboratory and in a commercial/Hungarian distillery. The experimental results of multivariable F-test (MANOVA) show that the scale of the fermentation and distillation – laboratory or commercial - has no impact on measured stable isotope ratios. This is a practical proof that the stable isotope database of the Forensic Institute can be used for the evaluation of the authenticity of spirits produced in any distillery.

Vehicle Fuel Emission Efficiency Estimation Using Multi-Linear Regression in Machine Learning

Vehicle fuel consumption and emission have been a great deal for global warming and the world economy. The impacts of CO2 emission can be minimized through optimization of engine design parameters such as Rated horsepower(RHP), Number of Cylinders and Rotors(NCR), Number of Gears(NG), and Equivalent Test Weight(ETW) to the Rounded and Adjusted Fuel Economy (RAFE). This article explorers the weighted impact of the independent variables RHP, NCR, NG, and ETW to RAFE using Multi-Linear Regression(MLR) in machine learning. For the proposed MLR method, the vehicle data is divided into two as training and testing. Then, the data cleanup process was applied to the training data to eliminate outliers that led to incorrect predictions. The proposed method determines the correlation coefficient to compare and seek the variables having less relationships with the dependent variable RAFE. Since there are no insignificant parameters in correlation analysis, MLR training was carried out by taking into account all parameters. Finally, the processed data are trained to create a multi-linear regression model. The obtained model is evaluated through Analysis of Variance(ANOVA). According to the ANOVA, there is a significant relationship between the dependent variable RAFE and the independent variables NG, ETW, and RHP with a p-value of 4.0994e-60, 1.5887e-48, and 2.5494e-31, respectively. Moreover, p-values of NG, ETW, and RHP are supported with F-test results of 227.73, 220.87, and 152.41. On the other hand, the obtained model is also relatively less affected by NCR, with a p-value of 0.031276 and an F-test of 4.94. As a result, the resulting MLR model can be used in new vehicle designs as it reveals which vehicle parameters affect CO2 emissions.

THE IMPACT OF SOCIOECONOMIC FACTORS ON PUBLIC HEALTH CARE EXPENDITURE IN ASEAN COUNTRIES

This study focuses on the macroeconomic, environmental, and socioeconomic determinants that would bring an impact on the healthcare. The ASEAN countries' economic growth, carbon emissions, urban population, and energy consumption are hypothesized to be correlated with healthcare expenditure. This study aims to investigate the impact of each factor affecting healthcare expenditure in these six ASEAN countries. The study looks into six ASEAN countries, i.e. Indonesia, Philippines, Thailand, Malaysia, Singapore, and Brunei Darussalam for the period of 2010-2014. A panel data analysis was conducted to meet the objectives of this study. To test the stationarity of the data, panel unit root tests including Augmented Dickey-Fuller (ADF) test and Phillips-Perron (PP) test were conducted. Next, Poolability F-test, Hausman test and Breusch-Pagan Lagrange Multiplier test had been carried out in order to select the best estimation model out of the three models which are Pooled Ordinary Least Square (POLS), Fixed Effect Model (FEM) and Random Effect Model (REM). Both ADF test and PP test suggested that all the variables were in stationary at second differencing with trend and without trend at the significance level of 1%. The following results of Poolability F-test, Hausman test and Breusch-Pagan Lagrange Multiplier test revealed that REM is the best estimation model to be applied in this study. Based on the REM findings, there is a negative relationship between economic growth at 1% significant level and HE that does not reflect Wagner’s Law in the context of this study. The finding of an insignificant relationship between carbon emission and HE at 1% significant level also does not reflect the Social Capital Theory which suggests that poor environmental quality and subsequent health damages lead to higher government health spending. The conclusion of this study had inferred that both economic growth and urban population have a negative significant impact towards healthcare expenditure in countries where private healthcare services, especially those located in urban centres, play important roles in complementing public healthcare services in serving the population. Meanwhile, carbon emission and energy usage are found insignificant to healthcare expenditure.

Nexus Between Financial Innovation and Financial Intermediation in Nigeria’s Banking Sector

This study evaluated the relationship between financial innovation and financial intermediation in Nigeria. It seems that banks in Nigeria may have a problem of deposit-loan mismatch and losing customers to start-ups given increasing cost of deposits attributable to disruptive practice arising from financial innovations. The specific objectives of this study were to examine the relationship between financial innovation (value of the automated teller machine, internet banking, mobile banking, point of sale transactions) and financial intermediation (commercial banks deposit mobilization) in Nigeria for the period 2009–2018. This study was anchored on the financial innovation theory of Joseph Schumpeter, which states that technology creates opportunities for new profits and super profits as a result of increased investment by banks or financial institutions on products of innovation. The ordinary least square was used to estimate the parameters. The data used were extracted from the Central Bank of Nigeria statistical bulletin. The results showed that there is a positive and significant relationship between financial innovation (value of Automated Teller Machine) and financial intermediation (commercial banks deposit mobilization) in Nigeria; there is a positive but no significant relationship between financial innovation (internet banking) and financial intermediation (commercial banks deposit mobilization) in Nigeria; there is a positive but no significant relationship between financial innovation (mobile banking) and financial intermediation (commercial banks deposit mobilization) in Nigeria; and there is no positive and significant relationship between financial innovation (point of sale transactions) and financial intermediation (commercial banks deposit mobilization) in Nigeria. The f-test result showed that financial innovations proxies jointly related significantly to commercial banks’ deposits. The work concludes that financial innovations contributed to commercial banks’ deposits in Nigeria. The researchers recommended among others that banks should improve on the security of transactions done on their platforms, continue to improve and partner with start-ups in technological infrastructure, improve on power and network stability, deploy more innovative products, and improve on the efficiency of bank staff by regular training.
