Abstract: In this study, the light had been shed on the relationship between of indicators stock market and business cycle in selected countries ,the study has been divided into three main chapters in order to test the validity of this hypothesis and achieving the aims of this study. The first one forms a conceptual and ideological of study and included three basic section. The second chapter dealt with Analyzing framework of study included two basic sections. While , chapter three has concentrated on the measure and analysis of the Feed back between stock market and business cycle. The study sample consist of six countries : USA, Mexico, Thailand, Malaysia, Korea, Egypt. It uses annual data covering the period (1983 - 2006).By using the Hsiao causality test has been used determine the direction of causality between indexes of stock market and business cycle.This study has yielded (concluded) many results from the theoretical and mathematical (econometric)First : "the conclusions of the theoretical aspect1 - Are the economies of industrialized countries over time, as with cases of depression and recovery, which affect to economic activity, and companies know that these conditions are strongly influenced by cycle companies, with sales booming with economic recovery and stagnation and decline in the shares of these companies know the stock prices rise as the periodic during the phase of prosperity and decline during the recession, the success of the investor depends on the type of the shares so to correct timing of the purchase 2 - The existence of a relationship and mutual influence between the work of primary and secondary markets, as the evolution and breadth of the work of the primary market leads to the development and expansion of the secondary market, through the development, diversification and expansion of new releases through the primary market, which offer the possibility of development and expansion of the secondary financial market activity, and using those issues later in their dealings, and in accordance with the clear understanding of this difficult chapter of the work and the development and expansion of these markets. 3 - financial derivatives is one of the most important features of modern financial developments during the last decade of the twentieth century, and these tools provide payments derived from other assets may be real or financial assets to cope with fluctuations and crises that have affected financial markets, which were used as tools to hedge against fluctuations in stock prices and rates interest and exchange rates. 4 - A shift in the characteristics of economic cycles, after the Second World War, becoming shorter courses "and less in terms of the duration of the decline in production or in terms of rates of deterioration in the indicators of economic activity and the disappearance of the global economic crisis as characterized by the unequal international distribution among countries capital, in addition to the lack of synchronization occur in those countries, but that this situation would be different during the eighties of the twentieth century and in the context of globalization has become the crisis overtaking the limits of all countries, whether developed or developing. 5 - The recurrence of financial crises and the breadth and speed of transition in the light of financial globalization is a controversial and attention to result in the damaging of a comprehensive and unexpected is not limited to the financial sector, but extends to other sectors and the effect of high economic costs have a negative effect not only in a crisis but extended beyond the borders to other countries. 6 - at the basis of the relationship between the performance indicators for the stock market situation of economic activity, the movement of stock prices is an important indicator to predict the economic cycle as they move in the opposite direction to the movement of bond prices, and up to the maximum level before the arrival of economic activity to the top of the recovery and up to lowest level before the arrival of economic activity to the bottom of the recession. 7 - The East Asian crisis occurred because of the big gap between the real sector and financial sector, which increased with the application of financial liberalization policies in the countries of East Asia, which has made the capital looking for a quick profit by speculating in the financial sector which has seen significant expansion and irresponsible, and take exercise role Parasitically hindering the process of economic growth, which has affected of the development the real economy and shot back, for the extent of the crisis and its spread from the center of the crisis (Thailand) It was during the economic vulnerability of financial markets and the integration of the global financial system. Through any channels of foreign trade and financial markets.8 - The degree of vulnerability of the Arab countries the financial crisis America is different from country to country, depending on the degree of economic openness and the degree of financial and economic development, countries are opening up the high and the Arab Gulf countries in particular will be more affected by and through the channels of oil and the dollar exchange rate stability. Second : the conclusions of the quantitative aspect 1 - The analysis showed that the standard linear model is the best expression of the models and the reality of the stock market in the United States. 2 - analysis showed that the standard non - linear model (Logarithm double) is the best model to reflect the reality of the stock market in each of the (Mexico, Thailand, Malaysia, South Korea, Egypt) 3 - The results of the United States signs an agreement with the estimated parameters form the logic of economic theory in terms of a direct correlation between stock market indices and the state of economic activity, except the number of companies that have demonstrated an inverse relationship because of the merger that took place between listed companies in the market. 4 - show a causal bilateral Feed Back casualty between stock market indices and the economic cycle, there is no impact of the market shares of economic activity is economic activity towards the stock market, which confirms the existence of a significant impact to the stock market on economic activity in the United States, as these are the efficiency of the market high. causal bilateral Feed Back casualty between stock market indices and the economic cycle, there is no impact of the market shares of economic activity is economic activity towards the stock market, which confirms the existence of a significant impact to the stock market on economic activity in the United States, as these are the efficiency of the market high. 5 - it seems that there is a causal relationship bilateral Feed Back casualty During the time lag between the first indicators of the stock market (the market index, the turnover rate) and the state of economic activity (economic cycle) in Mexico, in the direction of the market value, volume and the number of companies to the economic activity of the stock market, when considering the case of economic activity as the dependent variable.With the direction of the relationship when the stock market indicators as dependent variable of the independent variable (the case of economic activity) to the stock market indices, except the market value.6 - The results of measurement in Thailand and a positive relationship between stock market indices and the state of economic activity (economic cycle), it was determined to test the causal relationship that the two - way and at the failure except for the first time the number of companies. 7 - shows the measurement results on Malaysia as in accordance with the logic of economic theory, which pointed to the existence of a relationship between the soft variables, and confirmed through the test of causation and the existence of feedback between the stock market and the state of economic activity.8 - The results of South Korea in line with the logic of economic theory, which revealed the presence of a direct correlation between the stock market and the state of economic activity (economic cycle), which was evident from the test of causation as the two - way, except the number of companies.

Abstract: تزايد الجدل حول الدور الذي تؤديه السياسة المالية ومدى كفايتها في تحمل العبء المالي والمعبر عنها بالنفقات الجارية التشغيلية التي تتحملها حكومات البلدان المختلفة من اجل تقديم الخدمات العامة للمجتمع مهما اختلفت السياسات الاقتصادية للحكومة، بعد ما تزايد حجم | There has been a heated controversy over the role the financial policy plays and how sufficient it is in affording the financial burden. This burden is known as the operational current expenses which the governments of various countries mainly afford, despite the discrepancy in the government’s economic policy. After the deterioration and deficit in the state budget in all countries nowadays, it was necessary to find an appropriate mechanism so as to achieve the interaction and appropriateness between the main instruments of the financial policy on the realistic level with regard to their economy.This research aims to analyses the relationship between the main instruments of theState policy to encounter the increasing financial burden on the government, where the developing countries’ economy in general and Iraq’s in particular suffers from the financial policy’s inefficacy and feebleness due to the fluctuation of these governments’ policies. In addition, there is a lack of credibility for these governments to achieve a noticeable improvement that could create economic stability; especially most of the decisions made regarding the financial policy tend to be under the influence of policy makers.The study concludes that Iraq has been partially able to afford its operational expenses in spite of the economic, political, social, and security challenges he faced. Further, there was no active financial policy and a clear vision for attempting to diversify the revenue resources to depend on instead of depending on oil as the main source for taking the financial burden. In addition, Iraq economy suffers from a structural imbalance that negatively affects its capacity to diversify the revenues resources, while the financial policy has a significant place among other policies because it can play the major role in achieving the various aims due to its tools. These tools are considered as the most important economic administration tools in achieving economic stability and overcoming the problems of structural imbalance and weak economic diversification. As well as, the inveterate paralysis whirlpool in which the Iraqi economy has fallen into at the beginning of 2104 as a consequence of the heavy expenses of war on terror, not to mention the sharp decline of oil prices. The study provides a number of recommendations in which the most significant entails the necessity on working on diversifying the revenue resources for the Iraqi economy and to avoid depending heavily on oil and its derivatives. Also, there is a necessity of activating the non - oil revenue resources and working on their durability. For this purpose, rationalizing expenses strategy should be in accordance with the requirements of the Iraqi economy

Abstract: The contemporary business environment is surrounded by different challenges and pressures such as globalization , competitive advantage , continuous improvement , information technology etc, These should be taken in consideration if the business wanted to be able to complete with others and to achieve its objectives by attaining a clear success.A strategy, in general, is the plan of the higher management in the long - run, to achieve the results which coincide with the mission of the entities and its goals, this depends on what the management can do as to elements of strength and weaknesses, and how it should do to face the threats and opportunities.Strategy cannot be implemented without a strategic management; because it represents the ideas the management wishes to apply in a strategic approach in the management of economic entities.Strategic management can be on three levels, the level of the whole economic entity, or it can be on the level of each unit of activity, or it can be of the level of each functions level.The application of these strategies this should be coordinated and implemented, it must be noted that the functional strategy is very essential for the success of any secondary system in the economic entity, in order to reach the objectives. To be a successful strategy, the economic entity must take into consideration continuously, the needs of its customers, and to consider the changing of the environment and successful Factors, this is done by the use of certain techniques, vize, cost management which is a term used to describe the practices and action of management to reduce costs and to control it, in order to satisfy the customers. So this study aims at showing the role of cost management strategies techniques in the execution and evaluation of functional strategies through the guidance by strategies approach of cost management system.In order to complete this study, it was divided into six chapters to cover the theoretical and practical sides. The first chapter deals with cost management information and the contemporary business environment.The second chapter is about strategic management and functional strategies.While the third chapter take the study of cost management information and functional strategies.The fourth chapter is confined to the study of the present performance of the company in finance, production and costing.The fifth chapter displays the test of the proposed methodology to apply some cost management techniques to implemented and evaluate functional strategies.The last chapter is related to show the conclusions and recommendation which are arrived at through the theoretical and practical study.This study shows that the use of cost management techniques which helps the economic entity to ensure the basic factors of success, through data concerning external facts, rivals to rivals and customers, in addition to financial and non - financial data which are connected with these factors, in the fields of implementation and evaluating functional strategies, which are related to the success of the entity and reaching its gools and objectives.

Abstract: تسعى المنظمات الخدمية الى تحقيق ميزة تنافسية من خلال اختيار مواقعها بالقرب من الزبائن بهدف تسليم الخدمات بوقت قصير وزيادة عوائدها وحصتها السوقية وتصمم ترتيبها الداخلي بالشكل الذي يمكن من تسهيل تدفق الزبائن والعاملين والموارد والمعلومات بهدف تقليل صفوف واو | Service organizations select locations in a proximity to customers to deliver services quickly, and, meanwhile, increases their revenues and market share. The layout of such organizations should facilitate the flow of customers, employees, materials, and information, to prevent the creation of waiting lines and unwarranted waiting times. The survival of service organizations is hinged, to a great degree, on the right location and layout of such organizations; hence such decisions are conceived strategic in nature. The ongoing researches are still seeking to find scientific methods to help decision makers, in making decisions about the location and layout. This research studies the problem of selecting the location of fuel stations in oil products Distribution Company, and how to prioritize the location, as this decision is still facing the obstacles of complicated procedures and assumptions of decision makers. Furthermore dealing with the decision criteria as same importance without being subjected to the degree of influence of each on the decision. Concerning the arrangement of the fuel stations, they are arranged in a way that does not match with the assumptions of any queuing models, which require one server in each service channel and its reflection on the increase of waiting line and waiting time, which complicate the crisis. The study aims to design an integrated frame work for selecting the fuel stations location and arrange approvals for construction by applying analytic hierarchy process (AHP) on a sample of the stations that received the approval of construction in the company since 2008, using Criteria (ground, environment, social, engineering, legal, and services). Also, the queuing theory and simulation are used to study the proposed layout design for the fuel pumps according to queuing model M/M/s. Also, there was estimation for the performance standards to the proposed layout (number of cars on waiting, number of cars in service, number of cars in the system. filling quantity, filling time, waiting time, total time in the system, idle time) and comparing it with the actual performance standards for sample of fuel stations. The operating of the simulation models is based on a number of assumptions that reflect the actual reality together with the queuing theory. This study is important because its knowledge contribution of with service systems in general and the fuel stations in particular. Also the study provide objective solutions to the company by shortening the procedures and the time it takes to select the location and layout design in a way that achieve optimal investment in station space and reduce the waiting line, waiting time and idle time. Thus, this study is an attempt in Iraqi services environment through coincidence between the strategic decisions of operations management in one study. The study proved the efficiency of AHP and its ability to shortening time and efforts required to make decision of selecting stations location and arrange construction issue approvals, depending on set of criteria that have been identified in this study. Also, the simulation results confirmed the proposed layout performance standards exceed the actual layout performance standards. Finally, the study recommended the need to adopt AHP in selecting the location and granting approvals for construction of stations according to multiple criteria, and to adopt the proposed layout according to the queuing theory in designing layout of the fuel stations

The depression of dividend rates in the companies due to the existence of investment chances needs fund and improving its cash.2. The companies do not apply pecking in financing their capitals, and the results of asymmetric information analysis came congruent. The results confirmed the depression in asymmetric information between management and investors. almost companies didn’t make abnormal returns , on contrary the expected return excess the actual return.

Abstract: تعاني بعض الظواهر من وجود حالة اضطراب في بياناتها بالاضافة الى صعوبة صياغتها وخصوصا مع وجود عدم وضوح في استجابتها، او لكثرة الاختلافات الجوهرية التي تعتري الوحدات التجريبية التي تم اخذ هذه البيانات منها. فعندما تزداد المجاميع لمجتمع ما, لا يمكن اعتبار ذل | Often suffer phenomena and there is disturbances in their data as well as the difficulty of formulation, especially with a lack of clarity in the response, or the large number of essential differences plaguing the experimental units that have been taking this data from them. When growing groups of a population, it can't be regarded as a homogeneous population is increasing because the dispersion between the experimental units in response to that population as well as the error will also be increasingly difficult to build a model of that population.So there was a need to include an estimation method on the classification or underlying discrimination for these pilot units using discrimination or create segments for each item of these pilot units in the hope of controlling their responses and make it more in line style.Has been resorting to the use of the method of a modern and flexible classification is based on the neighborhoods between the views represented by the response variable by classification regression trees : CART. It was the use bayesian approach and the promise of features indicative of regression analysis model classification tree to take advantage of the above information by, and collect trees for explanatory variables are all together and at every stage fork on the other hand, represented the bayesian classification regression trees : BART.In view of the development in the field of computers and taking the principle of the integration of science it has been found that modern algorithms used in the field of Computer Science swarm of birds and other originally illustrated algorithm for the purposes of technology pertaining to distinguish between images or vibrational radio, etc., can be harnessed to serve the knowledge of statistics, which is based Turn on the information production and to achieve success in it. So is the use of genetic algorithm and submit a proposal by modified genetic algorithm, in addition to C4.5 and ID3 algorithms. And without losing the generality has been used as a tool of logistic analysis as important tool.It was a whole performance along with an estimate of the general additive model method of classification of all the methods mentioned in the above. Fitted model as modern and flexible overcomes curse of dimensionality that may occur most modern phenomena of the times when their data analysis.It was the use of simulated samples of different sizes (200, 400, 600) with (1000) replicates. The application was performed on patients with diabetes data for those aged (15) years and below are taken from the sample size (200) was withdrawn from the children hospital/ Al - Eskan/ Baghdad.As proof of the goodness of classification has been using the misclassification error, and as proof of the goodness of estimation has been using the root mean squares error.Was reached important conclusions through a process of differentiation among the six methods above, the superiority of the Classification and Regression Trees Algorithm (CART) is the best in terms of the results that has been reached in empirical side, when proposed Genetic Algorithm is the best in terms of the results that has been reached in applied side.

Abstract: The objective of this thesis is to obtain knowledge about the incorporation of ex ante accounting information to support operations management decisions in information systems. We focus on short - term and medium - term operations management decisions. Prior research and literature review show that present information systems lack the ability to generate ex ante accounting information for operations management decisions. We have identified three reasons why present information systems lack this functionality : 1. Accounting theories for decision support are difficult to implement in information systems.2. There are discussions in the accounting literature about which accountingInformation to use for decision support.3. Present data structures are inappropriate.The first problem area relates to the difficulties encountered when trying to translate the concepts of the accounting technique to support operations management decisions (the relevant cost technique) to information systems. The relevant costs of a decision alternative consist of the incremental costs and the opportunity costs. The incremental costs are those that differ between alternatives. Opportunity costs are the benefits foregone as a result of choosing one course of action rather than another. The definitions of the components of the relevant costs imply that these costs are situational dependent. The knowledge how to determine the relevant costs can be applied by humans. However, in the literature this knowledge is not formalized in such a way that this knowledge can be implemented in information systems.The second problem area relates to the conceptual discussion in accounting literature to the accounting information to use for decision support. Short - term accounting information (incremental cost plus known opportunity costs) sometimes directs companies to decision alternatives that are in contradiction to the directions companies would choose based on longer - term accounting information. Imagine, for example, that the full costs of making a component are above the purchase price of the same component, suggesting that in the long run the component could better be purchased outside. However, short - term relevant costs could very well be below the purchase price, because many costs are unavoidable in the short - run. How can organization ever achieve the objectives in the long run, whenShort - term information points in another direction? This confusion usually leads. To discussions in the literature about what type of accounting information to use for short - term decision - making (full cost or incremental costs).The final problem area relates to the registration methods of accounting data in most of the present information systems. The most common technique (double entry bookkeeping) blocks the use of accounting data for operations management decision support, since this technique does not incorporate ex ante accounting data. Therefore, we need other data models to serve our purpose. However, one of the main pitfalls in the design of accounting data models is that the data models limit itself too one application domain only (and therefore exclude others). Therefore, it is important to have a close junction with existing data models in order to obtain a larger application domain for the data. Literature provides two alternative models : the REA model and the ‘Grundrechnung’. These models claim to store accounting data objectively, meaning that they do not exclude any accounting application domain. However, the models relate to ex post functionality only, and not to the ex ante area meant in this thesis. Since we want to avoid the main pitfall in the design of accounting data models, the research effort should be aimed at the extension of the models in the literature. Based on the problems described above, we have formulated the following research questions : 1. What are the formal procedures to describe cost behavior in such a way that an information system can determine incremental costs and opportunity costs for a given decision - alternative?2. Which accounting technique can be used in information systems for theevaluations of operations management decisions in order to bring short - term Decisions in congruence with long - term policy?3. What are the implications of the accounting technique for the known accounting data models?The research objective has been pursued by the development of an information system design that is able to supply relevant ex ante accounting information for operations management decisions. The methodology of developing the information system design consists of three phases. In the first phase the stakeholders of the information system are involved to retrieve the requirements for such as system. In the second phase the requirements are used to build the architecture design. In the final phase a rationale is given which demonstrates that the architecture design, if implemented would satisfy the requirements of the stakeholders. In the methodology four groups of stakeholders are discerned : 1) the user, 2) the customer, 3), the architect and the software developer, and 4) the maintainer of the system. In this thesis, customer has not been involved as a stakeholder in this project. The reason for this is that the information system design is mainly in a conceptual phase. This makes it very premature to involve the customer as a stakeholder. The requirements have been based on the analyses how and which ex ante accounting information can be used for five operations management decisions. These decision are : 1) ‘setting the Master Production Schedule’, 2) ‘order acceptance’, 3) ‘determining lot sizes’, 4) ‘capacity expansion’, and 5) ‘determining safety stock levels’. Based on these decisions, in total five requirements have been defined for the system. These requirements, which are explained next are named 1) objectivity of accounting data, 2) resource consumption, 3) resource transition, 4) cash transition, and 5) contextual information. These requirements are fulfilled by the information system design. The information system design consists of two parts. The first part is the generic accounting technique to support operations management decisions. This technique is called the Hierarchical Cash Flow Model (HCFM). The HCFM consists of a set of procedures that is aimed at retrieving the effect of a decision - alternative based on objective parameters. The HCFM does not calculate with intermediate cost values regarding the use of resources. The HCFM only values the transactions with (external) customers and suppliers. The model gives answer to the first and second research question, described above. The HCFM makes a strict separation between the analyses of the effects on the resources flow and the analyses of the effect on the cash flow. The resource flow is analyzed by means of the concepts resource consumption and resource transition. Resource consumption refers to the usage of resources; resource transition refers to the purchase and sales transactions between the organization and its markets. Cash flows are retrieved by converting resource transition into cash transition. This possibility is created by making use of the contract concept. The contract concept enables the HCFM to model variability and avoidability of cash flows. We have introduced the operations management concept of hierarchical planning into our accounting model. Therefore, the HCFM extends the cash flow models known from accounting literature with this hierarchical concept. The result of this introduction is twofold. Firstly, the hierarchical concept enables the operational use of the opportunity cost concept in information systems. A higher hierarchical plan is used for a particular decision - alternative to determine the benefit forgone in this plan when executing the decision - alternative. Secondly, at the same time, the hierarchical concept is used to provide accounting information for shorter - term decisions that is in congruence with longer - term policy. The opportunity costs of the plan serve as a financial target for shorter - term decisions. In this way shorter - term decisions can be made in congruence with longer term policy, but at the discretion of the decision - maker. The hierarchical concept implements the requirement of contextual information.The second part of the information system design is the object model. The object model incorporates the data and procedures needed by the HCFM. The object model extends prior research effort into accounting data models, which has resulted in the Resource – Event – Agent (REA) model and the ‘Grundrechnung’. The object model is based oncontracts, activities, resources, and reservations. Accounting information is only related to contracts. This implies that we do not allocate or apportion accounting data, and therefore, fulfill the requirement of objectivity of accounting data. We have chosen to extend these prior models to avoid the main pitfall in the development of information systems for the accounting application domain. As mentioned above, this pitfall is a narrow focus on just one application domain, which causes the exclusion of other domains. By extending the prior models, the application domain of these models in maintained, which automatically leads to a multiple purpose focus of the accounting data. The HCFM is applied for two operations management decisions ‘setting the Master Production Schedule (MPS)’ and ‘order acceptance’ in an information system setting. We use this elaboration as a rationale to illustrate that the information system design is able to fulfill the stakeholders’ needs. However, the implementation of the HCFM is not straightforward. Modelling choices when implementing the decisions ‘setting the MPS’ and ‘order acceptance’ on non - financial grounds in present ERP systems lead to complexities when implementing the HCFM. We give solutions for these complexities, and then show that the HCFM is able to retrieve the accounting information needed to support these two decisions.

Abstract: Owing to economic changes in modern societies and the appearance of large companies, the economic entities have had a wide influence, either from the point of view of the national economy as a whole or at the numerous interested parties (stakeholders) in follow up activities of these entities.There is an opinion (normative view) that one of the objectives of accounting is to direct the behavior of the individuals and companies towards specific economic policies. An economic policy may require a high capital expenditure and a high income distribution in the circumstances of deflation and control (constraint) of investments during periods of inflation. The policy of income smoothing through the use of hidden reserves, investment credit, and the capitalization of research and development costs are best examples in this regards. The major objective of this study is to construct an accounting model which is able to satisfy the information needs of different parties, and at the same time maintenance to the current basic elements conceptual framework of accounting. The construction of this model depends on economic variables which affect the formation of accounting objectives, concepts, and methods of measurement and disclosure, in addition, it takes into consideration the specific environment of developing countries which Iraq is one of them. Were the capital market is weak, and the inability of market mechanism to play an important role in the allocation of resources in an efficient way, and the dependence of their economy on natural resources. This study is based on the main assumption '' Accounting concepts and practices derived from microeconomic & macroeconomic analysis '' followed by some secondary assumptions.To achieve the objectives of the study and to test its assumptions, the present study has been divided into seven chapters, the first chapter is for the methodology and previous studies. The second is for the theoretical background of conceptual framework for what the study classified as microaccounting and macroaccounting.The third chapter deals with the economic approaches of accounting theory. The fourth chapter focuses on the role of these approaches in the construction of the models of the financial reporting through a comparative analysis of the models of elected countries, including United States of America, Netherlands, Japan, and France. The field work contains two chapters (fifth & sixth), the fifth examines the relationship between economic environment and regulation of accounting in Iraq, and its reflection on the current accounting practices. The sixth chapter verifies coefficients relationship between the elements of the financial reporting model by using the statistical methods. The seventh (last) chapter introduces the suggested model, conclusion and recommendations. The most important conclusions are as following : 1. The dependence of microeconomic approaches , in accounting theory on the competitive structure as a model for theorizing, is a clear pondered over in abstract ,compared with real world where competition is absent sometimes, and monopolies exist in many times, and related the competitive structure with political, social, and legal factors in all times. 2. The appearance of macroeconomic approaches in accounting theory was caused by two main factors : A. The emergence of new social goals for business organizations and society as a whole.B. The appreciation of political influence by society in general and by those concerned with accounting and setters of accounting standards. Hence these parties adduce his efforts to clarify and solve economic and social issues through these approaches.The study offered a number of recommendations such as : 1. The necessity benefits from different economic environment variables included in this study, especially characteristics of each economy, as well as addition the economic behavior of individuals, in order to construct accounting models. 2. Specification of the parties affected by accounting standards and determine economic and social relationship which bind these parties before choosing the suitable approach to formulate and setting accounting standards. 3. The study of probable economic consequences of the accounting standards, before issuing it. Because there are no accounting standards which has an equal effect on all parties, the accounting standards may lead to re - distribution of wealth and income at entity level and at the economy as a whole

Abstract: سعى البحث الحالي لاهداف عدة منها، تحديد طبيعة العلاقة بين بديل القياس المحاسبي وبين طرائق اصلاح الوحدات الاقتصادية العراقية، وكذلك تقييم مداخل بدائل القياس المحاسبي المستخدمة في اصلاح الوحدات الاقتصادية العراقية المتعثرة (*)، فضلا عن اصلاح تلك الوحدات، وه | The current research sought to achieve many goals like : determine the nature of the relationship between the accounting measurements and alternative methods of reforming Iraq's economic units, as well as evaluating alternative accounting measurements entrances used in reforming Iraq's troubled economic units , also this method makes the way to select and applicate of accounting standards very easy depending on the alternative information used to reform these economic units. The methodology focused on the only way to reform which is privatization that is often the result of lack of accounting information because of losing the alternative accounting measurement methods application to choose the best way of reform , which is resulted some important questions like : is the alternative accounting measurements used provided useful information and consistent with the economic reform method in troubled economic units? Are there any difficulties in application of suitable alternative accounting measurements to reform troubled units? In order to assess whether the reform method actually used in the Iraqi economic units consistent with alternative measurements to reach to the alternative accounting measurement application steps to reform Iraqi troubled economic units, so I conducted a field survey of Iraqi troubled economic units and choose (4) economic units belonging to the ministry of industry because these units have sought to apply the methods of economic reform and meets the reform indications as well as data available to the research that consistent with economic reform methods by determining the alternative accounting measurements that fit Iraqi methods to reform economic units and analyze some financial statements before and after applying the reform method. The research set some conclusions the most important was : the sample of economic units suffer from not using alternative accounting measurements to reform which result in transform to losing units and resort to borrow which depletes the company resources with huge rise of management expenses and inability to adapt and competitiveness. The research set many recommendations as follows : the process of identifying the problem of troubled economic units can be properly by gathering available information and then make the right decision by choosing the best way economic reform, also the necessity to create a new account in the special accounting guide to unified the accounting system applied in the public sector because of increases occurring in assets value as a result of re - evaluating within a separate account in equity as indicated in the relevant international accounting operations

Furthermore, it shows the FRQ effect on important variables e.g. dividends and the market value. Therefore, the need to study this topic is important to clarify the ambiguity of its implications. This dissertation aims to provide a diameter of the FRQ level of the companies listed on the Iraqi Stock Exchange. Moreover to show the FRQ effects on the dividend policy and it is reflection on the market value. Finally, this study proposes a model in order to measure the FRQ. Many conclusions have been driven by the researcher, the most important of them are shown hereunder : 1. The proposed model is the best among all the models because, of its explanatory power which is the highest compared with other models. However the explanatory power of all the models was found to be low, the reason behind that is because of combining both the cash and stock dividends together that may be result because of the less cash dividends during the research period.2. The company’s market value has increased in the Iraqi Stock Exchange due to the effect of FRQ on the Dividends. The total effect on the market value confirms this point through combining both the direct and the indirect effect. Based on the conclusions of present dissertation the researcher has recommended many of points, the most important of them are shown below :

Abstract: ان الخاصية الاساسية لتمييز البيانات المكانية عن بيانات السلاسل الزمنية هي الترتيب المكاني للمشاهدات , وعينات البيانات المكانية تمثل مشاهدات ترتبط بنقاط او مواقع وتتميز هذه البيانات بان ارتباطها يضعف كلما بعدت المسافة وكذلك تتميز بتدرج المكان (( المناطقية | The main property to differentiate the spatial data from time series data is the spatial arrangement of observations and the samples of spatial data represent observations related to points or locations these data are distinguished with the weakness of their connection each time the distance getting far away and the place graduation (location)on the spatial relations of observations are represented in matrix named spatial weights matrix. The spatial econometrics is used in following up the spatial effects like the spatial dependence of observations in different points of place, and spatial heterogeneity arising from relations or parameters model that change with sample data in each time we move within the place , those two points have been neglected in traditional econometrics because of their sinconsistency of statistical assumptions and when taking those spatial effects into consideration ,the statistical influence will be of high efficiency. On the contrary, ignoring these effects will lead to loss the information and will not be as efficient as the dependant sample.Because of the difficulty of deriving the posterior function (on which the Bayesian inference depends) up on applying the Bayesian methods especially in cases that the number of probable models is very large as computing the posterior functions for all these samples requires integration for large dimensions functions which is very difficult Mathematically or inapplicable that requires proper methods can deal with such cases like Gibbs and Metropolis - Hastings sampling by analyzing the posterior distribution to number of conditional distributions for each parameter in the model and then the simplicity of inference for each parameter in the model.The matrix of spatial weights is built by registering the contiguity relations for each location with others in a matrix row (w?) and given (1) if there is a relation between two locations (wij=1) and zero, if it doesn’t (wij=0)as i and j refer to the rows and columns in sequence. For making the summation of each row in the matrix w? equal to 1 , the elements of matrix will be calculated according to the proportion : wij/ ?wij and i=1,2…,n j=1 Consequently, we will get the adjusted matrix W.The practical side was focused on the counting of spatial autoregressive model parameters, and these parameters is the vector ? and it is an ordinary regression parameters vector, and error variance parameter (?2) , and the most important of them is a countig of the parameter (?) which is represent spatial dependance parameter.In order to show the role of the spatial, the practical side included taking the real population for childrens between(1 - 19) year, that had iron deficiency anemia (due to from iron deficiency) that admitted to children’s hospitals in Kurkh district of Baghdad (which had been divided into five geographic regions) for 2010. We have suggested that computing the elements in the adjusted matrix to be on basis of the actual length proportion of the joint borders among different locations that lead to get the accurate estimated value of spatial dependence parameter، where value result of spatial dependence parameter (?) was (0.43) when use Metropolis - Hastings sampling method while value of this parameter when use spatial outoregressive function and by using the adjusted matrix was( 0.57) and value of this parameter when use the same regression function but by using the suggested matrix was (0.85).

Because of the importance of the project management, several institutes and specialized entities in project management submitted number of project management maturity models which aim to determine the level of the project management maturity in organizations and companies. However, there is still a need to submit a perfect maturity model containing the characteristics which the other international models have; besides the characteristics the models have ignored in addition to some characteristics submitted by writers and researchers to be a guide that helps organizations and companies to assessment the level of the project management maturity and to continue improving it. The study aims at designing a project management maturity model and then to apply it to a sample company of the Ministry of Construction and Housing. The study also aims at designing a system for evaluating assessment the level of the project management maturity by using programming languages (Microsoft Visual Basic 6.0) and Data Base (Microsoft Access) to construct the data base system. in order to calculate the average level of the project management maturity and to count the two indicators of cost and scheduling performances, and in the light of them particular basics will be deterring the projects are classified according to excellent , success and challenge. as well as detraining the failing projects in some of the excellent , successful and challenged by the management of the project and high administration The system has been designed in a general form and it is not confined to handling the case related to the sample study.An example case is taken from the Ministry of Construction and Housing to fulfill the aims of the study, the method of studying was taken into account so as to obtain all the required data and information to apply a sample project management maturity in it.The researcher, together with teams of evaluation in the companies dealt with, performed the evaluation of the level of the project management maturity and using the project maturity level evaluation system afterwards to determine the level of project management maturity and to determine the indicators of cost performance and scheduling performance and classifying companies’ projects to several categories as well putting a plan to improve the level of the project management maturity in the companies dealt with.The study has reached several conclusions such as : The results of the study showed that the studied companies have achieved the level of project management maturity distributed between the two levels (1) and (2) of maturity which pointed out that the contracting companies in the Ministry of Construction and Housing are still in the beginning of maturity because they did not apply the concepts and philosophies related to the project management maturity and The results of the circumstances the constructional industry sector went through. The study recommends adopting the application of the Project Management Maturity Model (PM3) in the companies studied to see the truth of the project management maturity in them to be the starting point to improve the project management maturity which calls to adopt the guide of the Project Management Body of Knowledge (PMBOK) to realize activities which include plans, procedures, jobs, activities, rules and methods and ways related to each operation of the project management operations

Abstract: ان عملية التقدير لمعلمات انموذج المعادلات الانية بالطريقة التقليدية من المواضيع المهمة والتي كتب عنها الكثير من البحوث والدراسات وهذه البحوث تختلف باختلاف الاساليب المتبعة في عملية التقدير الا ان التقدير بالطرق البيزية لهذه المعادلات وخصوصا عندما يكون ال | The process of estimation of parameters of the following equations has been done by the traditional method and being considered as an important subject. Many researches and books have been written about the subject and these researchers are different from one to another depended on the methods followed up. But the estimation with Bayesian methods for these equations , especially when the internal variables (classified binary ) being considered one of the subjects that have not been researched greatly. Thus , the researcher has tried to shed light on some methods of Simultaneous equations in case of binary variable by using the classic method and Bayesian method , along with a suggested way that being applied on the samples of the relationship between blood pressure and psychological pressure. The researcher has used the classic method and considered it as raw information for using the method of Bayesian in estimating the Simultaneous equations system. It has been compared between the classic method and Bayesian method and also methods of Bayesian with the suggested method according to the measurement of ( Mse) for specifying the better method for estimation. Problems have been specified lying in non - functionalizing the former information about the parameters in the process of estimation by using the known traditional methods and that lead to the less efficiency if not using it. Thus , it should resort to other methods as method of tradition , The goal of the study is to know the mutual interaction between the blood pressure and psychological pressure and comparing the traditional and Bayesian method in the estimation of Simultaneous equations of internal variable , classified binary by using many methods for Bayesian estimation with the suggested method for getting to estimations that are more close to values of the real parameters. it has been reached to many results ,most of which is the Bayesian method and suggested method that have been better in estimation than the classic method, besides there are mutual effects between blood pressure and psychological pressure and the most losing functions in estimation which is the " Q losing function"

Abstract: حاولت الدراسة قياس وتحليل اثر مؤشرات السياسة النقدية على الاستثمار الاجنبي المباشر لدول مختارة مع اشارة خاصة الى اقليم كوردستان العراق وقد استخدمت الدراسة اساليب التحليل الوصفي والكمي في البحث لاجل تحديد مدى اثر السياسة النقدية على الاستثمار الاجنبي المبا | AbstractWitness the current international environment major shifts and unprecedented, which is the result of the phenomena of globalization and economic reform as well as the information and communications revolution that has made the world a small village where all barriers have been removed in front the transfer of money, labor, goods and services, capital, and in this framework intensified international competition to attract foreign funds and companies' capital Multinational through the removal of barriers and obstacles that hinder their way and give them incentives and guarantees that facilitate the arrival and entry to the local market in view of the role played by foreign direct investment in the provision of savings (funding) needed to establish productive projects and the transfer of technology and contribute to the improvement of skills, experience and drive economic growth.From here come the great importance of foreign investment in the economy of any state and is seen as a form Lease alternative to the indebtedness of foreign loans and is seeking states promoted and stimulated a climate conducive to creating his all its components, and if the foreign investment flows is endemic by 70% in the major industrialized countries, that what with its attractive in all aspects of the investment climate, and this was the duty of all especially the developing countries than you want to catch up with the evolution and development that is working hard to bring this type of investment to the best of effort and means, to the important role of foreign investments in development projects Economic host countries if these countries are well done and the choice of projects to choose its foreign partners.Monetary policy is one of the investment climate and one of the most important determinants of FDI aspects and is done through indicators included exchange rates, interest rates, inflation, and the question that arises here is what is the way to make monetary policy tools as a catalyst to attract foreign direct investment and this is what we will try to answer it In this study.It is the exchange rate one of the key policy variables in the economic openness while affect macroeconomic variables such as trade, capital flows, foreign direct investment, inflation, global reserves, and GDP as well as financial transfers, while the longer inflation indicator of the stability of the domestic economy in the host countries, Changes in rates of inflation in the domestic or foreign countries expect a change in net returns as well as investment decisions idealism and then is expected to have a negative impact on foreign direct investment, and the interest rate, the rise in the mother country would make it attractive to foreign capital and will cause the rate of the exchange rate rise and this will lead to increasing the supply of foreign currency, on the other hand, if interest rates were high in other countries, investments will leave and it produces diminishing supply of foreign currency rates, which is heading the exchange rate to decline.China, Egypt, was one of the most important countries that have worked to restore economic structure and enact legislation giving attractive incentives to the flow of foreign investments as well as monetary and fiscal economic policies that contribute to achieving this purpose, taking into account the difference between the above - mentioned two countries in terms of the degree of advancement and development and economic growth.With regard to Iraq, and because of the important role of expected foreign direct investment in Iraq, part of this study care diagnosis climate Iraqi investment environment and reality and identify obstacles to actively carry out an investment actor in the Iraqi economy and work hard to create an environment and conditions appropriate Iraqi investment environment that can help to motivate and attract domestic savings or foreign investment through various mechanisms, including monetary policy in Iraq and Kurdistan Iraq Study experience an attractive environment for investment to some extent for foreign direct investment.The study concluded that both exchange rate and inflation play significant, positive and negative role on consecutive in attract foreign capital flows, but the interest rate was non - significant perhaps this is due to the institutions finances and Banking in Iraq generally undeveloped.Also, this study prove that are multifactor (Security, Economy, Political, Managemental and Society) negatively effect on the investment environment in Iraq making it a rejecter environment.Also, the study found that the amount of foreign direct investment is small which is only about, (5.7) billion dollars from (2006 till 2014), as well as, the distribution of investments varied amongst the various sectors or on the levels of the three governorates in Kurdistan province.

Abstract: The conversional industry is the main driven engine for the large number of the developing countries it is the more effective tool for converting economy from low value activities to values generate fast development rate have the ability to provide more prospects for sustainable development, so that the support of the conversional industry sector be the main target for any Comprehensive developmental policy. The most important targets of our study are discovering the deviations imbalances may take place in Iraqi industry sector particularly the public industry sector searching for the level of the industry sector performance figure out the causes of the failures analyzing the future of the conversional industry under the economic transitions and the changes challenges which the surrounding conditions will excrete on it. This study aims to determine the effects economical and social expenses which are caused by the new economic trends which are represented by activating the free market mechanisms on the conversional industry sector as well as determining the general industries features which are best adapted to the economical transitions which are supposed to mitigate the pressure of the free market. Many international local conditions imposed core reforms on the conversional industries to be changed gradually from a economy driven by governmental decisions like governmental manufacturing to economy driven by market mechanism, so that this study tries to highlight the new international and local conditions are forced the economy to be market economy. Our example is the failure of the governmental manufacturing to achieve the economical objective is the sustainable growth.
