Effect of the capital Sufficiency in evaluating the Banking and financial performance

THE IRAQI MAGAZINE FOR ADMINISTRATIVE SCIENCES, Volume 13, Issue 53, Pages 24-52

The aim of the research is to identify the impact of capital adequacy in the financial performance indicators. A sample selected from the Iraqi private banks amounted to 14 banks, a period of (10 years), from year (2005) until year (2014). The main hypothesis of research is that the positive and strong relationship between these indicators and financial performance banking important in achieving banking superior financial performance, which can attention to the independent variables (capital adequacy indicators) that directly impact in promoting financial performance indicators, which will reflect positively on the various aspects of the local economy, and thus can mitigate the effects of the various crises that can be exposed to if we have a sound banking sector of the Iraqi economy.
They have reached the researchers at the end of their search to a set of conclusions, including the disparity study sample banks in the ratio of capital to total assets, and this marks the great disparity in the adoption of administrative, regulatory and investment frameworks, especially when we consider that the increase in the proportion of capital to total assets hurt in the interest of the depositors it provides them with protection against risks, but it reduces and limits the profitability of shareholders and investors in banks.

"A comparative study between LASSO-MAVE method and Adaptive LASSO-MAVE method for variable selection in semi-parametric single index models

THE IRAQI MAGAZINE FOR ADMINISTRATIVE SCIENCES, Volume 13, Issue 53, Pages 197-215

The semi-parametric single – index model (SSIM) are important tools and basic to treatment the problem of high – dimensional , As it plays an important role in the process of model building and variable selection of significant . in this research has been the use some methods variable selection of automatic modern and that work on estimation vector of parameters β and link function g (X^T β ) With variable selection at the same time for semi-parametric single-index model are LASSO -MAVE method and Adaptive LASSO - MAVE method for aim to improve the accuracy and predict of the model . in order to achieve this aim , it was conducted simulation experiment to show methods preference used in estimation and variable selection for model under study by using different models , different variances , different sample sizes and different correlation values as well as the use of a real data of influencing factors on market value share for the banks sector in the iraqi stock exchange for purpose of comparison and a check from performance these methods in practice . it was reached through simulation experiments and a real data to conclusion showed favorite Adaptive LASSO - MAVE method as it gave better results from LASSO-MAVE method depending on the two criteria Average mean squared error (AMSE) and Average mean absolute error (AMAE) basically for Comparison , and were obtained on results depending on program R- package.

The Intermediary Effect of Organizational Chaos in the Relationship between Organizational Conflict and Psychological Empowerment

THE IRAQI MAGAZINE FOR ADMINISTRATIVE SCIENCES, Volume 13, Issue 53, Pages 216-249

This study aims at determining the intermediary effect of organizational chaos in determining the quality of the relationship between organizational conflict and psychological empowerment. Due to the increasing cases of organizational conflict at Karbala University and the emergence of cases of chaos at many faculties, researchers have to conduct this study.
Methodology: The descriptive method was used to measure the study variables. The sample of the study included the Master and doctorate Degree holders in all the faculties of Karbala University. The sample was randomly selected. It included 332 of the study population (1711) . A number of statistical methods were used, such as measuring exploration factor and effect relationships between the variables of the study.
Findings: The study found that the organizational conflict affects the increasing of the organizational chaos with a small significant level. It was found, also, that the organizational chaos affect two dimensions of psychological empowerment. Moreover, there was a relationship between the organizational conflict and decreasing the psychological empowerment.
Organizational values: The studies, which considered the conflict and the organizational chaos, have not been applied to universities, however this sector suffers from conflicts at all levels, may be as a result of intense competition. When viewing previous researches, we did not notice the application of these three variables, which has a significant effect on the outputs of academic work.
Future researches can benefit from this study in studying each dimension of conflict, measuring its direct effect on the dimensions of psychological empowerment, as well as studying the positive effect of the conflict and the creative chaos.
