The previous work of Bachok et al. (Heat Mass Transf. 47:1643-1649, 2011) on the forced convection heat transfer on an isothermal moving surface in an external free stream is extended to the case when fluid injection through the surface, characterized by the parameter γ, is large. The asymptotic solution derived in this limit shows that the boundary layer has a double region structure, with an inviscid inner region of thickness O(γ) and an outer shear layer. Some further aspects of the original problem not treated in Bachok et al. (Heat Mass Transf. 47:1643-1649, 2011) are discussed as well as the analogous problem for a constant surface heat flux, where relatively small injection rates are seen to give rise to large increases in the surface temperature. © 2012 Springer Science+Business Media Dordrecht.

This paper presents both a numerical and analytical study in connection with the steady boundary layer flow and heat transfer induced by a moving permeable semi-infinite flat plate in a parallel free stream. Both the velocities of the flat plate and the free stream are proportional to x 1/3. The surface temperature is assumed to be constant. The governing partial differential equations are converted into ordinary differential equations by a new similarity transformation. Numerical results for the flow and heat transfer characteristics are obtained for various values of the moving parameter, transpiration parameter and the Prandtl number. Approximate analytical solutions are also obtained when the suction or injection parameter is very large. It is found that dual solutions exist for the case when the fluid and the plate move in the opposite directions. © 2011 Her Majesty the Queen in Rights of Australia.

Stress testing is an appealing risk-management tool because it provides risk managers with additional information on possible portfolio losses arising from extreme, although plausible, scenarios. In a volatile financial environment, stress tests have recently become more important as an instrument to gauge the impact of specific adverse developments in the economy. Stress testing may be increasingly used by financial firms for both internal and external purposes. This Article offers a conceptual framework for defining stress testing, describing its possible applications, highlight certain techniques developed to conduct this testing including a few methods for identifying stress scenarios and survey its recent use by supervisory agencies. The usefulness of stress tests as risk management tool crucially depends on the choice of stress scenarios: if the scenario is too implausible, the stress test results will be ignored by management. There is no generally accepted standard how to choose scenarios. Many institutions apply some standardized scenarios derived from extreme market moves in the past. In addition, stress scenarios can often be an effective communication tool within the firm and to outside parties, such as supervisors and investors.

The cost type informaion should be considered an instrument for creating value at a lower cost. Besides, this approach shows the capacity of the cost information system to supply relevant information which serves for several purposes, i.e. its use in the financial accounting (the cost of acquisition, the cost of production or stock processing, the absorption cost, the sale cost and the period cost); the use in decision making (opportunity cost, relevant cost, irreversible cost); the performance appreciation (measurement) and management (hidden costs, controllable costs, externalized costs).

The definition provided in the standards for the financial instruments contains as key-elements the notions of financial assets and debts. A first classification of the financial instruments consists in their grouping in financial assets and debts.

Operational risks have received an increasing emphasis in the recent years. These risks were considered to be qualitative rather than quantitative. In its 1998 paper on operational risk management, the Basle Committee stated that most big losses in the banking industry resulted from internal control weaknesses or lack of compliance with existing internal control procedures. After years one of the important innovations of the future adequacy of funds own proposed by the Basel Committee on Banking Supervision through Basel Accord II is to require an adequate coverage of operational risk capital. These have urged banks to develop their own advanced capital measurement approach (AMA) to manage operational risk. Beyond principles related to the implementation of an approach for calculating such capital, the purpose of this study is to analyze the practices of banks in measuring and managing operational risk and explore regulatory perspectives on the subject.

The proposed article refers to the statistical analysis of the evolution of key indicators of economic development that characterize Romania's sustainable development during 2000-2009. Nowadays economy focuses on innovation and development. The indicators of economic development represent a cornerstone tool in the system of sustainable development indicators (SDIs). The knowledge society focuses on progress, but the economic development based on sustainability must take into account environmental aspects. Based on research results, the article will reflect the possible future evolution of indicators in the context of sustainable economic development of Romania. The paper also suggests the need of designing and establishing an economic environment that, through its inputs and outputs, is compatible with the dynamic natural environment and the needs of present and future generations to coexist and succeed. In this way, the paper will weigh the pros and cons of the relationship between economic development and environment in the context of sustainable development of the country.

Various reform measures asked to introduced by BIS have indeed strengthened the EU (and global) banking system in preparation for the fresh global challenges ahead. This paper reviews the banking sector reforms policy known as Basel III, crucial issues and some parts agenda for the future. The paper ends with the future measures of Basel III for the banking industry, to compete continuously with the challenges from a global perspective. Moreover, these ratios are high, the more they can prevent bank runs and limits the occurrence of crises. This reduces the uncertainty and loss of production.
