Z. Mahmood
             The current research aims to identify the impact of ambidextrous leadership behaviors on organizational energy in Al-Faris Company. The descriptive analytical method was used as a research approach. Adept leadership includes two dimensions (open leadership behaviors and closed leadership behaviors), and organizational energy includes three dimensions (emotional energy, physical energy, and cognitive energy ). The research sample included all the administrative leaders (General Manager, Associate General manager, Department Manager, Division Official  ) in AL-Faris Company / the Iraqi Ministry of Industry. The researcher distributed (74) valid questionnaires after retrieving (53) questionnaires, and the research relied on the statistical package (SPSS). The results indicated that there is a strong effect and a high correlation between the research variables. The most important dimensions of ambidextrous leadership behaviors are open leadership behaviors, which have a high impact on organizational energy. However, there is a weakness in the involvement of individuals in decision-making and the advertising side AL-Faris Company

Distinguishing Shapes of Breast Cancer Masses in Ultrasound Images by Using Logistic Regression Model 应用Logistic回归模型识别超声图像中乳腺癌肿块的形状
Luay Adil Abduljabbar, Omar Qusay Alshebly
The last few years witnessed great and increasing use in the field of medical image analysis. These tools helped the Radiologists and Doctors to consult while making a particular diagnosis. In this study, we used the relationship between statistical measurements, computer vision, and medical images, along with a logistic regression model to extract breast cancer imaging features. These features were used to tell the difference between the shape of a mass (Fibroid vs. Fatty) by looking at the regions of interest (ROI) of the mass. The final fit of the logistic regression model showed that the most important variables that clearly affect breast cancer shape images are Skewness, Kurtosis, Center of mass, and Angle, with an AUCROC of 88% and an Accuracy of almost 89%. We also came to the conclusion that the Fibroid mass is small and less white than the Fatty mass
在过去的几年里,医学图像分析领域的应用越来越广泛。这些工具帮助放射科医生和医生在做出特定诊断时进行咨询。在这项研究中,我们利用统计测量、计算机视觉和医学图像之间的关系,以及逻辑回归模型来提取乳腺癌的影像学特征。这些特征通过观察肿块的感兴趣区域(ROI)来区分肿块的形状(肌瘤与脂肪)。logistic回归模型的最终拟合表明,明显影响乳腺癌形状图像的最重要变量是Skewness、Kurtosis、Center of mass和Angle,其AUCROC为88%,准确率接近89%。我们还得出结论,肌瘤肿块比脂肪肿块小,白色较少

Estimation of Reliability through the Wiener Degradation Process Based on the Genetic Algorithm to Estimating Parameters 基于遗传算法的维纳退化过程可靠性估计方法
Mostafa Abdul-Jabbar Dawod, Entsar Arebe Fadam
      In this paper, the researcher suggested using the Genetic algorithm method to estimate the parameters of the Wiener degradation process,  where it is based on the Wiener process in order to estimate the reliability of high-efficiency products, due to the difficulty of estimating the reliability of them using traditional techniques that depend only on the failure times of products. Monte Carlo simulation has been applied for the purpose of proving the efficiency of the proposed method in estimating parameters; it was compared with the method of the maximum likelihood estimation. The results were that the Genetic algorithm method is the best based on the AMSE comparison criterion, then the reliability was estimated by an inverse Gaussian distribution according to the characteristics of the Wiener process. It was also applied based on real data taken from an experiment intended to determine the degradation in the light intensity of lamps under specific experimental conditions
在本文中,研究人员建议使用遗传算法方法来估计维纳退化过程的参数,其中基于维纳过程来估计高效产品的可靠性,因为使用传统技术仅依赖产品的失效次数难以估计高效产品的可靠性。通过蒙特卡罗仿真验证了该方法在参数估计方面的有效性;并与极大似然估计方法进行了比较。结果表明,基于AMSE比较准则的遗传算法方法是最优的,然后根据Wiener过程的特点,采用反高斯分布对可靠性进行估计。它还应用了一个实验的实际数据,旨在确定在特定的实验条件下灯的光强的退化

Semi parametric Estimators for Quantile Model via LASSO and SCAD with Missing Data 基于LASSO和SCAD的缺失数据分位数模型半参数估计
Aws Adnan Al-Tai, Qutaiba N. Nayef Al-Kazaz
In this study, we made a comparison between LASSO & SCAD methods, which are two special methods for dealing with models in partial quantile regression. (Nadaraya & Watson Kernel) was used to estimate the non-parametric part ;in addition, the rule of thumb method was used to estimate the smoothing bandwidth (h). Penalty methods proved to be efficient in estimating the regression coefficients, but the SCAD method according to the mean squared error criterion (MSE) was the best after estimating the missing data using the mean imputation method

The Quality of Audit Work Under Expert System 专家制度下的审计工作质量
Eman Jasem Mohammed, Salma Abdullah
The research aims to extrapolate the repercussions of the use of expert systems in the work of the external auditor on the quality of audit, as the research problem was that despite the use of these techniques in audit work, there is a problem related to the efficiency and effectiveness of these technological systems used in audit work, the feasibility of their use and the extent of their impact: The quality of the audit process. The researchers adopted the questionnaire as a tool for collecting study data from a community composed of auditors in auditing offices and companies in Iraq, and the auditors of the Iraqi Federal Financial Supervision Bureau. The number of recovered and valid questionnaires reached (100), or 76% of the total number of questionnaires distributed. The researchers concluded several results, the most important of which was that the auditor in auditing offices and companies in Iraq, in addition to the auditor of supervisory bodies, are aware of the positive effects of using expert systems in the work of the external auditor on the quality of audit work. The researchers also concluded many recommendations, the most important of which are: the need for the regulatory authorities, whether in the public sector represented by regulatory bodies, or audit offices and companies, to benefit from these modern technologies, the need for professionals and audit offices to invest in this modern technology, the need to integrate modern technologies related to the accounting profession And auditing the curricula of Iraqi universities, institutes, and colleges

A Comparative Study for Estimate Fractional Parameter of ARFIMA Model ARFIMA模型分数参数估计的比较研究
Ammar Muayad Saber, Rabab Abdulrida Saleh
      Long memory analysis is one of the most active areas in econometrics and time series where various methods have been introduced to identify and estimate the long memory parameter in partially integrated time series. One of the most common models used to represent time series that have a long memory is the ARFIMA (Auto Regressive Fractional Integration Moving Average Model) which diffs are a fractional number called the fractional parameter. To analyze and determine the ARFIMA model, the fractal parameter must be estimated. There are many methods for fractional parameter estimation. In this research, the estimation methods were divided into indirect methods, where the Hurst parameter is estimated first, and then the fractional integration parameter is estimated from it by a relation between them. As for direct methods, the fractional integration parameter is estimated directly without relying on Hurst's parameter, and most of them are semi parametric methods. In this paper, some of the most common direct methods were used to estimate the fraction modulus namely (Geweke-Porter-Hudak, Smoothed Geweke-Porter-Hudak, Local Whittle, Wavelet and weighted wavelet), using simulation method with different value of (d) and different size of time series. The comparison between the methods was done using the mean squared error (MSE). It turns out that the best methods to estimate the fractional parameter is (Local Whittle).       The ARFIMA model was generated by a function programmed by the MATLAB statistical program
长记忆分析是计量经济学和时间序列中最活跃的研究领域之一,人们已经引入了各种方法来识别和估计部分积分时间序列中的长记忆参数。用于表示具有长记忆的时间序列的最常用模型之一是ARFIMA(自动回归分数积分移动平均模型),其差异是一个称为分数参数的分数数字。为了分析和确定ARFIMA模型,必须对分形参数进行估计。分数参数估计有许多方法。在本研究中,估计方法分为间接方法,首先估计Hurst参数,然后根据两者之间的关系估计分数阶积分参数。直接方法不依赖Hurst参数直接估计分数阶积分参数,多为半参数方法。本文采用了几种最常用的直接方法(Geweke-Porter-Hudak、Smoothed Geweke-Porter-Hudak、Local Whittle、小波和加权小波),采用不同(d)值和不同时间序列大小的模拟方法来估计分数模量。采用均方误差(MSE)对两种方法进行比较。结果表明,估计分数参数的最佳方法是(局部惠特尔)。ARFIMA模型由MATLAB统计程序编制的函数生成

The Role of Internal Audit in Assessing the Risks of Management Decisions regarding Strategic Operations )Acquisition) 内部审计在评估战略经营管理决策风险中的作用(并购)
Najat Saleem Yousif, Safaa Ahmad Mohamed
The research aims to verify the Role of Internal Auditing in Assessing the Risks of Strategic Operations (Acquisition) and then reflect on management decisions. Since all corporations wish to expand, growth and domination of the market may expose them to multiple risks that lead to failure. The research assumes two main hypotheses. First, there is no role for internal audit in evaluating the strategic operations (acquisition). Second, there is no relationship between internal auditing in assessing the risks of strategic operations (Acquisition) and management decisions. The data was collected by using a questionnaire distributed to a group of private bank employees. The statistical analysis regarding research rejected the two hypotheses and accepted the two alternative hypotheses, which stated that there is a role for internal audit in assessing the strategic operation’s risks (Acquisition) and that there is a significant relationship between internal auditing in assessing the risks of strategic operations (Acquisition) and management decisions. Among the most important conclusions reached is that  an internal audit is so important in determining  the risks regarding decision making for acquisition. The important recommendation is to activate  the role of internal auditing regarding acquisition. The value of the research clarifies the role of internal auditing in assessing the risks of acquisition processes and encourages the adoption of the idea in the Iraqi environment. It’s considered as one of the recent research as it keeps pace with developments in the world
本研究旨在验证内部审计在战略运营(收购)风险评估中的作用,进而反思管理决策。由于所有公司都希望扩张,市场的增长和统治可能使他们面临导致失败的多重风险。这项研究提出了两个主要假设。首先,内部审计在评估战略运营(收购)方面没有作用。其次,内部审计在评估战略运营(收购)风险和管理决策之间没有关系。数据是通过向一组私人银行员工分发问卷来收集的。关于研究的统计分析拒绝了这两个假设,接受了两个备选假设,即内部审计在评估战略运营(收购)风险方面发挥作用,内部审计在评估战略运营(收购)风险与管理决策之间存在显著关系。得出的最重要的结论之一是,内部审计在确定与收购决策有关的风险方面非常重要。重要的建议是激活内部审计在收购方面的作用。该研究的价值阐明了内部审计在评估收购过程风险方面的作用,并鼓励在伊拉克环境中采用这一想法。它被认为是最新的研究之一,因为它与世界的发展保持同步
