...Corporate helping hand Zahurul Alam The role of the private sector in the global economy has increased over the years. In Bangladesh, the private sector's involvement in the economy has steadily increased over the last two decades. According to some estimates, the sector accounted for more than 99% of the exports, 93% of the employment, and 75%, 73% and 89% of the investment, fixed assets and value added, respectively, in 2004, against 26%, 71%, 29%, 66% and 44% respectively in 1980. The situation has not changed radically since then. These figures highlight the necessity of the role that the private sector should play in conducting socially responsible business as an integral part of its corporate social responsibility. The simple logic is that, with the enormous share in the economy, a sector's passive role in worker and social welfare would not allow the country's major development indicators attain the expected level to compete in the global arena. More importantly, the sector with overwhelming share of employment, income generation and investment should proceed with ethical business and strive to make a positive contribution to the society. Integrated in the business, the obligation of corporate social responsibility (CSR) is the pathway to attaining a sustainable positive impact of business on society through socially responsible business. Although CSR as a concept came into being in the 1980s, with the recognition of business's social and environmental......

Development of Accounting Theory Based on Islamic Teachings

...an inbuilt accountability mechanism. Generally the accounting should be able to perform roles like keeping safe custody of interests, certifying true and fair view of business, enabling accountability and providing reliable information for successful decision making to all the stakeholders. In this context there are three main issues with respect to present system of setting accounting standards. These are undue pressures of certain groups in setting these standards, no role of owners in setting these standards, and flexibility/discretion in applying these standards which may lead to subjectivity. These may results in incorrect valuation of business transactions, increasing management discretion which in return will increase corporate governance issues including incorrect financial reporting, earning management and limiting decision making ability of the stakeholders. In order to overcome to this situation there is an urgent need to revamp the accounting theory in such a way that when it is put into practice it performs its due role as being, discussed here. The best way to correct this situation is to develop a new accounting theory based on Divine guidance. In this background, the Islamic principles of “Amanah” (Custody) (Amer2007), “Shahadat” (Testimony), (Amer, 2008)...

Horan Claremont Graduate University, ABSTRACT The e-Gov field (also called Electronic Government, Digital Government, Electronic Governance, and similar names) emerged in the late 1990´s. Since then it spurred several scientific conferences and journals.

...Accounting Information System Tutorial 7 – Audit and Corporate Governance Instruction: Answer the following questions 1. What are the differences between COSO and COBIT internal control framework? At a high level COSO is focused on processes and controls for financial reporting, while COBIT is focused on IT When we think of most organizations, these often go hand and hand (financial information is often supported by IT in that the information relies on systems and applications (i.e. storage, recording, transforming, etc...). COSO - supported by five organizations: Institute of Management Accountants (IMA), the American Accounting Association (AAA), and the American Institute of Certified Public Accountants (AICPA), the Institute of Internal Auditors (IIA) and Financial Executives International (FEI). COBIT - supported by ISACA, an international professional organization focused on IT governance. 2. Why do the companies need to do the audit? The shareholders are apart from an organisations management although they partly own a company; therefore they need to get a fair understanding of the company’s performance. Also the stakeholders such as the creditors, suppliers, customers and etc. need to have a fair understanding a company to make a decision. 3. Discuss the responsibilities of internal audit, external audit and audit committees. Internal audit is a management tool, and forms part of the company’s internal control structure.

Problem of Bd Capital Market

...Introduction Investment Climate means the general economic conditions affecting the financial markets. A favorable investment climate encourages businesses to improve efficiency and productivity in order to increase revenues and capital available for investment. It also gives investors confidence in the market and encourages them to invest more capital. Investment Climate The investment climate in a country is the collective set of incentives which establish the “rules of the game” to which economic actors must adhere. Set by a wide variety of sources, including government policies, cultures of public administration, and institutional, social, and physical infrastructure, the investment climate determines the level and uncertainty of returns expected by economic agents and consequently impacts the quality and quantity of investment and the incentives to productively employ inputs. The investment climate can be broken down into the following three main areas: (1) Macroeconomic and Trade Policy - The capacity of domestic institutions and economic policy (e.g. fiscal, monetary, trade, and exchange rate policy, administration of customs and ports, security of property rights, strength of rule of law, and political stability) to reduce costs of international trade and finance and ensure a consistent and non-distortionary basis for investment, production and exchange; (2) Microeconomic Framework - The contribution of microeconomic regulation (e.g. rules......

History of Ais

...resource planning (ERP). Before, with separate applications to manage different business functions, organizations had to develop complex interfaces for the systems to communicate with each other. In ERP, a system such as accounting information system is built as a module integrated into a suite of applications that can include manufacturing, supply chain, human resources. These modules are integrated together and are able to access the same data and execute complex business processes. With the ubiquity of ERP for businesses, the term “accounting information system” has become much less about pure accounting (financial or managerial) and more about tracking processes across all domains of business. [edit]Software architecture of a modern AIS A modern AIS typically follows a multitier architecture separating the presentation to the user, application processing and data management in distinct layers. The presentation layer manages how the information is displayed to and viewed by functional users of the system (through mobile devices, web browsers or client application). The entire system is backed by a centralized database that stores all of the data. This can include transactional data generated from the core business processes (purchasing, inventory, accounting) or...
