The disclosures leave more valuable information in the hands of investors to be used in appraising the performance of firm as a whole and its constituents. In view of changing customer and geographic profile of software industry situated in India, the present paper evaluates the segment reporting practices of listed IT firms which are required to comply with the mandatory Indian Accounting Standard No. 17 on Segment Reporting. The analysis finds a yawning gap between the prescriptions of the standard and actual reporting practices. Firms fail miserably in providing voluntary segment information which could be of shareholders value. With the ushering in of International Financial Reporting Standard |IFRS] regime in India in 2011, a qualitative improvement may be seen in the days ahead.展开更多

In addition, the fossil fuel reserves is facing rapid depletion on the earth. Currently, most researches have concentrated on producing biogas for heating, lighting, drying, cooking but lack in researching on electricity production because the possibility of producing biogas at households are common at small scale. Studying on alternative energy sources to replace traditional fuel for electric power generation brings new chances and great opportunities for development. This study presents an assessment electric power generation via water hyacinths and agricultural waste. In this paper, the evaluation electric power is generated by operating internal combustion engines which use biogas fuel to replace traditional fuel (diesel, gasoline). The results of the studies were demonstrated by experiments on the renewable energy production system at Hoa An Biotechnology Research and Experimental Center of Cantho University.展开更多

In the appraisement of enterprise human resource, there is a great amount of linguistic-value information. In order to improve the reasonability of the result of appraisement of enterprise human resource, we need to study the methods for processing the linguistic-value information. In this paper, a 2-stages method is proposed for processing the linguistic-value appraisement of enterprise human resource. At the first stage, we choose the experts familiar with the related field according to the appraisement goal and problem. At the second stage, we combine the appraisement results by D-S evidence theory or LOWA operator according to the nature of linguistic variable.展开更多

To achieve desired results, managers have to implement methods of evaluating and mitigating risk as part of a process well elaborated. Security risk management helps managers to better control the business practices and improve the business process. An effective risk management process is based on a successful IT security program. This doesn't mean that the main goal of an organization's risk management process is to protect its IT assets, but to protect the organization and its ability to perform their missions. During this process, managers have to take into consideration risks that can affect the organization and apply the most suitable measures to minimize their impact. The most important task is choosing the best suited method for analyzing the existing risk properly. Several methods have been developed, being classified in quantitative and qualitative approaches of evaluating risk. The purpose of this paper is to present the advantages and disadvantages of each approach taking current needs and opportunities into consideration.展开更多

We developed an evaluation model to make a general metrics for circular economy system of industrial chains. The development of the evaluation tree drew upon five factors to identify the structural complexity. The evaluation model generated unitive entropy information from six data definition (node, level of community, metabolic span, degree of node, number of relation and connectivity of node) according to the evaluation tree. The industrial chains of Tashan circular economy park of Datong Coal Mine Group and Gujiao circular economy park of Xishan Coal-Electricity Group were evaluated by the proposed method. The key factors stunted by the decline of structural complexity were identified and the unitive metrics of entropy information of the industrial chain was shown for realigning the circular economy systems.展开更多

The findings show that what the raters perceived as affecting the rating included training, raters' interaction with the rating criteria, raters' physical and emotional conditions, raters' attitudes towards the rating work, raters' oral English proficiency level, and the recording quality. Raters' educational and research background were perceived not to affect the rating.展开更多
