Foreign Reserves of the Central Bank of Iraq and its Influence on Foreign Investment Flows (Applied Research in the Period 2004 - 2019)

The importance of research results from its analysis of a major economic variable, which is foreign investment in an unstable environment that has not been witnessed by any country in the world. And because the research is applied, it has used real data on the work of the Central Bank of Iraq. Therefore, the results they will obtain are concrete results, And the problem of research may therefore be summarized by the following question: Has the Central Bank of Iraq been able to contribute to attracting foreign investment via its foreign reserves?. To prove the main premise of the research, “there is a significant statistical relationship between the Central Bank of Iraq's foreign exchange reserves and foreign investment” the standard quantitative approach has been applied, and the research reached several conclusions, The relationship between the Iraqi Central Bank's foreign assets and foreign investment is positive, and this fits into the theoretical details of the research, which reflects the success of the goal of accumulating such reserves, especially since they increased in the period under discussion, It also reflects the success of the Central Bank of Iraq in managing these assets.

THE NEXUS BETWEEN THEEXTERNAL SECTOR AND INFLATION IN NIGERIA, 1985 -2018

The interaction between different economies in the global market could have impact on their key economic variables. Hence, this study set out to examine the impact of the external sector on a key economic variable in Nigeria being Inflation. The study utilized time series data from 1985 to 2018 which was subjected to Augmented Dickey Fuller Test. The next step was to subject the data to an ARDL cointegration test. The result showed that in the short run and long run external sector variables do not have any significant impact on inflation in Nigeria. The paper suggests that money supply and fiscal policy should be used to control inflation in Nigeria.

Economic Impact of COVID-19 on the Vulnerable Population of Bangladesh

This study aims to find out the Economic condition of the vulnerable population of Bangladesh in the COVID-19 situation. This study uses the primary data of 203 respondents who were collected from all around Bangladesh using convenience and purposive sampling during the first wave of the COVID-19 pandemic. In this study, a comparison of expected income in the COVID-19 situation is made with the pre-COVID-19 situation using Welch two-sample t-test, and the possible impact on Expenditure and Savings is discovered using OLS estimation. Descriptive analysis is also included considering the key economic variable of the respondents. This study finds a significant drop in income due to the COVID-19 pandemic and infers that it will cause both drop-in expenditure and monthly savings. Moreover, this study gives an overall idea of the situation of vulnerable people in the COVID-19 situation. This paper intends to help the stakeholders and policymakers to understand the situation of the vulnerable population of Bangladesh during the COVID-19 pandemic.

Well-Being at Work: A Cross-Sectional Study on the Portuguese Nutritionists

This exploratory, nationwide cross-sectional study was performed to investigate the well-being of Portuguese nutritionists, in addition to outlining their professional and demographic profile. Descriptive analyses were carried out to determine the measures relating to centralising tendency and dispersion of the sample. We compared means and proportions through t-tests and Analysis of Variance (ANOVA). The sample size was 206 individuals, respecting a minimum of eight respondents per item to validate the instrument. We recruited Nutritionists from Portugal nationwide using the list of electronic mail provided by the Order of Nutritionists. We sent an electronic mail to all the Nutritionists registered in this Order. We also used messaging applications and social networks (Instagram, Facebook) to reach Nutritionists who were not accessing electronic mail. Most respondents are women (92.5%), young (mean age = 31.4 ± 8.07 years; 54.2% of participants aging under 30 years), single, and with no children. More than half are Catholic (73.8%) and have less than ten years of nutritionist undergraduate completion (55.4%). The only variable that influences well-being at work is the economic variable Household Monthly Income. Those who earn less than €500.00 per month perceive themselves at a lesser state of work well-being than those who earn from €2501.00 to €5000.00 per month.

The Application of "Sets" of Discrete Mathematics everyday in life

<p><em>Mathematics is related to something that can be calculated or something expressed in terms of quantity (number). There are so many economic variables (concepts) that are quantified, such as the price of goods, the amount of goods demanded and offered, the money supply, the level of profit sharing margin, national income, investment level, and so on. Mathematics does not only play a role in quantifying economic variables, but also explores the relationship between economic variables. The relationship of an economic variable with other economic variables is often expressed in the form of an economic model. Because economic variables can be quantified, these economic models can be expressed in the form of mathematical symbols / models.</em></p>

Innovation Techniques Analisys in Macroeconomy on Ratio of Financial Islamic Bank

This study aims to investigate macro-economic variables on the financial ratios of Islamic banks in Indonesia, using simultaneous impulse response function (IRF) and forecast error variance decomposition (FEVD) analisys. The object in the sample research is one of the Islamic banks in Indonesia, namely the bank muamalah. The data used in this study consists of 4 macroeconomic variables of Indonesia and 4 variable ratio of Islamic banks in Indonesia. From the research that has been done macro economic variable response is still very volatile in the first month until month 10, positive and negative response (up and down) since the occurrence of shock or shock to the variable banking sector. Next, from the 9th to the 10th month the fluctuations begin to shrink meaning that the macroeconomic variables are no longer very volatile like the previous period. By using Impulse Response (ROA) in the results that in the first period of variable banking ROA ratio is strongly influenced by FDR shock (12.6%) while the period of the period of shock ROA and other variables still not give influence.

Cloning data with unchanged estimates of estimable non-linear functions of parameters

Non-linear regression models occur in the fields of biology, banking, economics, and sociology, population and biological growth. The absolute growth, growth of humans, and most importantly, an economic variable is appropriately described by non-linear regression models. In this article, we present cloned datasets for bivariate and multivariate non-linear regression models with the same non-linear regression fit. The application of such cloned datasets is used for the confidentiality of sensitive data for publication purposes. In this article, we present cloned data sets which will yield the same fitted non-linear regression models.
