Abstract
This paper aim aims to predict the quantities of water needed in the city of Baghdad for the next 10 months. This paper focuses on potable water, based on the time series data of the water consumption phenomenon in the city, which was obtained from the Ministry of Water Resources, specifically the Baghdad Water Department. Statistical forecasting techniques were used on the monthly water consumption data for the city of January 2014 until May (2024, a total of 125 months, and that is Baghdad in the period from to reach an estimate of the quantities needed by the city of Baghdad in the future. Curve Estimation and Linear Regression forecasting techniques were used, such as linear regression analysis and the Box - Jenkins (ARIMA) methodology, to obtain the best water consumption model in the city of Baghdad and the most accurate. In This paper we concluded that it is the best model suitable for predicting monthly water consumption in Baghdad city is (3,1,1) ARIMA among the models proposed in the Box-Jenkins methodology in terms of accuracy measures and (Mean Absolute Percentage Error) which reached (2.44-MAPE).While the (Mean Absolute Percentage Error) for the Simple Linear (MAPE=8) Quadratic Regression model and the Quadratic Regression model were also found, the research concluded that monthly consumption will increase in the city of Baghdad, when compared to Between the actual values and the predictive values of the methods used in the paper to predict the future. Finally, it is recommended to take the necessary measures to limit water consumption in the city, through pricing, awareness, education, intermittent supplies and other measures that preserve water resources and achieve sustainability.
Abstract
This study aimed to measure the impact of fair value indicators (net realizable selling value, asset replacement cost, net future cash flows) on investment efficiency as measured by the market value per-share to earnings per share model and the deviation from the expected investment model. The study followed a descriptive analytical approach to interpret the relationship between its variables. The study population consisted of extractive and mining industry companies listed on the Amman Stock Exchange for the fiscal years (2019-2023), totaling (7) companies. To analyze the data and test the hypotheses, the following statistical methods were used: (descriptive statistics, test for stationarity in time series, Durbin-Watson test, Hausman test, multiple linear regression, simple linear regression), relying on the statistical software (EViews).
The study concluded that there is a positive impact of fair value indicators (net realizable selling value, net future cash flows) on investment efficiency as measured by the market value per-share to earnings per share model, while they had a negative impact on investment efficiency as measured by the deviation from the expected investment model. Additionally, the study found that the asset replacement cost has a positive impact on investment efficiency as measured by the deviation from the expected investment model, and a negative impact on investment efficiency as measured by the market value per-share to earnings per share model.
Based on the results of this study, the researchers concluded with several recommendations, the most important of which were: the necessity for extractive and mining industry companies listed on the Amman Stock Exchange to expand their disclosure of financial information related to fair value indicators with clarity and transparency to attract investors and gain their trust.
Abstract
This research aims to identify the role of strategic leadership, through its dimensions (clarity of strategic direction, rational use of authority, and ethical and value framework), in achieving outstanding performance in the private universities included in the research sample. (153) valid questionnaires were distributed to the research sample, which included senior and middle management. The data were processed and analyzed using several statistical methods, most notably (arithmetic mean, standard deviation, coefficient of variation, Pearson correlation coefficient, and simple linear regression) using the SPSS V28 statistical software. One of the most important conclusions reached by the research is the existence of a statistically significant correlation between strategic leadership (with its three dimensions: clarity of strategic direction, rational use of authority, and ethical and value framework) and the level of outstanding performance in private universities. This indicates that adopting these dimensions contributes to enhancing the universities' ability to improve their focus on beneficiaries, develop their internal processes, and improve their human resource management as key inputs for institutional excellence. The research recommends the necessity of adopting an integrated strategic leadership system in private universities, based on developing clear and updated documents and strategies, promoting organized delegation of powers, establishing the ethical framework, building leadership and human capacities, and supporting a culture of innovation and continuous improvement, in a way that contributes to raising the levels of institutional performance and achieving excellence in the higher education environment.

Abstract
The study aims to achieve several objectives, the most important of which is to analyze the nature of the financing behavior adopted by business companies, by measuring the impact of financing behavior—represented by short-term debt, common stock, and retained earnings—on Economic Value Added (EVA) using the EVA model for a selected sample of business companies listed on the Iraq Stock Exchange during the period from 2005 to 2024. The study relied on the descriptive-analytical approach to present the theoretical and analytical aspects of the research variables, and the quantitative approach to test the research hypotheses in order to address the research problem, which revolves around the question: To what extent does financing behavior affect the Economic Value Added of industrial companies listed on the Iraq Stock Exchange? The study assumes a main hypothesis positing the existence of a statistically significant impact of financing behavior on the economic value of industrial companies.

Abstract
This research aims to diagnose the impact of the quality of bank assets from loans and credit loans on cash flows generated from operating activities by studying a sample of commercial banks listed on the Iraq Stock Exchange for a period of 10 years from 2010 to 2019. The research used the descriptive analytical approach based on the SPSS statistical program by measuring the strength of the correlation between the study variables by simple linear regression and continuity of chains. The problem of the research was whether cash flows through operating activities are affected by the quality of bank assets? The research found that there is a positive moral impact between the quality of assets and cash flows. The quality of assets is a good indicator of the predictability of future cash flows as a result of the direct relationship and the positive impact between them. This encourages banks to focus on achieving the quality of assets with the aim of obtaining cash flows from their operating activities. The research recommends the need to reduce the proportion of non-performing loans through credit undertakings and by managing the potential risks of bank loans and other assets while at the same time adopting sustainability policies that achieve high profitability ratios and thus high cash flows.
