Survival analysis is one of the types of data analysis that describes the time period until the occurrence of an event of interest such as death or other events of importance in determining what will happen to the phenomenon studied. There may be more than one endpoint for the event, in which case it is called Competing risks. The purpose of this research is to apply the dynamic approach in the analysis of discrete survival time in order to estimate the effect of covariates over time, as well as modeling the nonlinear relationship between the covariates and the discrete hazard function through the use of the multinomial logistic model and the multivariate Cox model. For the purpose of conducting the estimation process for both the discrete hazard function and the time-dependent parameters, two estimation methods have been used that depend on the Bayse method according to dynamic modeling: the Maximum A Posterior method (MAP) This method was done using numerical methods represented by a Iteratively Weighted Kalman Filter Smoothing (IWKFS) and in combination with the Expectation maximization algorithm (EM), the other method is represented by the Hybrid Markov Chains Monte Carlo (HMCMC) method using the Metropolis Hasting algorithm (MH) and Gypsum sampling (GS). The study was applied in the survival analysis on dialysis until either death occurred due to kidney failure or the competing event, represented by kidney transplantation. The most important variables affecting the patient’s cessation of dialysis were also identified for both events in this research .

The research dealt with green marketing and its role in achieving the goals of production organizations, as the research was concerned with the production organization under discussion and its marketing process, which is the Euphrates Tables Factory for the production of plastic tubes.
The research presented its problem related to the effect of green marketing in achieving the goals of the organization under discussion and what are the most influential dimensions in the marketing process, and the researcher sought to achieve a set of goals based on the two main hypotheses of the research. The owners of the shops and companies that consume the product and the total sample number was (50) individuals, and the researcher used the SPSS statistical analysis program to statistically process the data and extract arithmetic averages, standard deviations and percentages of the sample answers. The results showed positive attitudes towards both green marketing and the goals of the organization.
The researcher mentioned a set of conclusions and recommendations at the end of the research based on these results.

Understanding performance efficiency is a basic concept for any commercial business, especially ports, measuring achievements against specific goals and objectives, and the efficiency of port performance is measured through comparison with other homogeneous ports. This research looks at the performance of container terminals' berths in Iraqi ports after running through ports. Iraqi experience of joint operation with the local and foreign private sector. The results of this research should assist port officials in identifying the efficient co-operating companies and the least efficient co-operating companies, how the lagging companies improve their productivity and who are the reference companies that they should emulate.

In a time of financial globalization, many financial markets in the light of the technological and informational revolution intend to cooperate and be linked with other markets.” This matter has led to the occurrence of many agreements and treaties between the financial markets of these countries, the purpose of which is to open up between the markets and allow the movement of capital to be more liberal. Many markets have gone through structural changes with the aim of removing restrictions on the movement of capital and adopting the means of technological progress, which in turn requires attracting a lot of capital flows. This research aimed to measure the relationship, interconnectedness and merger between the Gulf financial markets, and the coefficient was studied. The correlation between these markets and the knowledge of the correlation of each market with each other.” The general index of the financial market was relied upon for a period that extended from the first quarter of 2006 to the third quarter of the year 2020. While there are (6) interlinkages of a somewhat small value, it is possible in the future to increase the agreements between these countries, and through the correlation coefficient of the financial markets in In the Arab Gulf countries and the Gulf financial market indicators, we see that there is a high merger in most of the financial markets in the Arab Gulf, as well as what the agreements between the financial markets of the Arab Gulf states have clarified

The study aimed to verify the extent to which Iraqi industrial companies apply the theory of constraints in production processes and its reflection in creating a competitive advantage among companies in the market.

In light of the adoption by many countries of economic reform programs, the introduction of market mechanisms and the orientation towards integration into the international economy through the international banking market, Jordan adopted the approach based on openness to this market by relying on the liberalization method for the services sector, including banking services, in a manner that allows the natural presence of foreign banks in The Jordanian banking market, especially in light of the existence of international agreements regulating the work of these banks in light of an international competitive economic environment, and since Jordanian banks, like other developing country banks affiliated with the World Trade Organization, operate in a growing local competitive environment that may be exposed to competition challenges by banks Foreign workers working in Jordan. The research tries to shed light on the commercial presence of foreign banks operating in the Jordanian banking market, especially in light of the increasing number of branches of these banks, which would be reflected in the most prominent indicators of financial inclusion in them.
