The study uses profitability, liquidity, leverage, market ratio, size and cash flow as proxies of accounting information. Cumulative abnormal return and market adjusted return are used as stock return variables. The samples of the study are listed companies in manufacturing industries that actively trading between 2003-2006 in Indonesia Stock Market. The study finds that profitability, turnover and market ratio has significant impact to the stock return. The result consistent with previous studies Hobart （2006）, Utama and Santoso （1998） and Restraningsih （2007）.展开更多

SEC-PSO, which is designed with the concept of energy conservation, can solve the problem of premature convergence frequently appeared in standard PSO algorithm by partitioning its population into several sub-swarms according to the energy of the swarm and is used in the optimization strategy for parameter identification and operation condition optimization. The run-to-run optimization exploits the repetitive nature of fed-batch processes in order to deal with the optimal problems of fed-batch fermentation process with inaccurate process model and unsteady process state. The kinetic model parameters, used in the operation condition optimization of the next run, are adjusted by calculating time-series data obtained from real fed-batch process in the run-to-run optimization. The simulation results show that the strategy can adjust its kinetic model dynamically and overcome the instability of fed-batch process effectively. Run-to-run strategy with SEC-PSO provides an effective method for optimization of fed-batch fermentation process.展开更多

One of the major purposes of accounting is to help investors provide reliable, comparable and accurate information. If accounting data are informative about fundamental values and changes in values, they should be correlated with stock price changes. This study provides theory and evidence showing how accounting variables explain stock returns and examines the relationship between the stock returns and accounting variables of listed non financial companies in ISE-100 Indice for 2006-2008 period by using panel data methodology. Empirical analysis consists of 192 observations of 64 companies in years 2006-2008 to examine the effects of inventory, accounts receivable, gross margin, operating expense, return on assets, cash flow, leverage, liquidity, price/earnings, return on equity on stock returns. The results of the study confirm that the predicted roles of fundamental factors and stock returns are significantly related to gross margin, cash flow, leverage and equity variables. The model explains about 13.35 % of the variation of annual stock returns with the leverage variable with most of the significant power.展开更多

The paper assesses the impact concentrate on the IFRS adopter countries and at the same time on the Business Valuation Standards （BVS）, because they provide consistence and comparability, in time and in space, to the valuation even different implementation levels of the accounting information system （AIS）. The results corroborate that rules and practices are not sufficient conditions to create a widespread accounting language, and international institutional standards play an essential role in framing financial reporting characteristics, in order to assist financial analysts and accountants to implement the accounting system and strategies, as well as, on firms to adopt the best valuation practices on their disclosures. Also, the authors recommend that the International Accounting Standards Board [IASB], the Securities and Exchange Commission [SEC], the European Commission [EC] and valuation agencies should now devote their efforts to harmonizing valuation standards rather than harmonizing accounting standards.展开更多

The objective of this article is to examine the quantitative relationship between the firm size and the quantity of accountants working for the firm. In this paper, the employees, sales revenues, and total assets in a firm are employed to measure firm size. The authors collect and analyze the data of 436 listed firms from the Chinese Shenzhen Stock Exchange. The result of this study indicates there is a positive relationship between the firm size and the quantity of accountants employed by the firm. The study also establishes the multiple regression equation, which can be used to predict the quantity of accountants of listed firms. And it provides a way to predict the quantity of accountants of legal organizations.展开更多

Thus, comparable accounting information is clearly important, and this study plans to confirm the level of comparability of net income and equity of companies in the financial sector （in Brazil, ＂Finance and Others＂）, listed in the stock exchange, futures, and commodities （BM＆F Bovespal）, issued according to Brazilian Generally Accepted Accounting Principles （BR GAAP） and the IFRS. This study is descriptive, using a quantitative approach. Data were collected from secondary sources, more specifically, from the explanatory notes in the financial statements of the companies listed in the financial sector of the BM＆F Bovespa in the fiscal year of 2010. The results showed a reasonable level of comparability, with 68% of the companies presenting materially comparable information for net income and 72% of them for equity. However, decisions made based on data issued following the two different standards may have suffered the influence of asymmetric information; in other words, the comparability of information did not seem to satisfy those companies during the studied period of time. The main limitations of this study were data collection and selection for the development of the research because of： （1） inconsistence in net income and equity reconciliation criteria in the companies investigated; and （2） lack of uniformity in designating the adjustments that affect net income and equity in the conversion of the BR GAAP standard into the IFRS.展开更多

The findings show that the disclosure level has improved, but the overall level is still low and unable to satisfy information users; there is positive correlation between corporate size, industry type, accounting firm's type and corporate environmental dis-closure index. The companies of large scale and heavy pollu-tion and those audited by international "Big 4" and domestic "Big 10" accounting firms have a high level of environmental disclosure, while the profitability and financial leverage has no impact on the disclosure level. Finally some suggestions are put forward to establish environmental information disclosure sys-tem in China.展开更多

Sample of the study includes 129 companies selected from 6 major sectors at CSE. Cross sectional and time series cross-sectional regressions are used for the data analysis. Study finds that earnings per share （EPS） and returns on equity （ROE） have a significant impact on market price. However, the explanatory power of combined variables is below average. Further, value explanatory power of earnings has considerably improved after the new information technology adoption at CSE. This study is unique because it examines the impact of technological advancements on value relevance of accounting information probably as the first paper to be applied on Sri Lanka.展开更多

The authors construct a model considered of three main stock market effect factors： cognitive factors, social factors and economic factors. In the simulation system, free-scale social network is generated for information relations among investors in stock market. The authors simulate the organization information propaganda processes and generate stock related news. The generated news contains economy factors and sudden events. Stockholders cooperate with the related stockholders in their social network, and make stock exchange decision based on this news and their cognitive understanding of this news. Simulation results shows that the social network news propaganda effect stock prices. If social network in stock market have circles, the news affection will be amplified.展开更多
