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 study has conducted a univariate analysis of the Tobin's Q and the market-to-book ratio for the period before and after the cross-listing by using paired tests. Non-cross-listed firms are then included in multivariate regressions by using pooled Time Series Cross Section (TSCS) and Panel Corrected Standard Error (PCSE) regressions for a period of 13 years to find out if there is a difference in the valuations between cross-listed firms and non-cross-listed firms. The study's results indicate that the Tobin's Q of cross-listed-firms increases two years prior to cross-listing and that it continues to increase two years after cross-listing. The market-to-book ratios also show an increase two years prior to cross-listing and up to one year after cross-listing, then decrease in the second year after cross-listing. When non-cross-listed firms are included in the analysis, results indicate that cross-listed firms are valued higher than non-cross-listed firms. When data are portioned for positive earnings per share (EPS) and dividends, results indicate that valuation is the highest when EPS is positive. Since segmentation theories cannot be ruled out, the study's findings are more in support of the growth opportunity hypothesis.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 study reveals that, compared either with the U.S. and Japan at similar stages of industrialization or many developing and developed nations at different income levels, China has certain advantages when it comes to the improvement of its workplace environment. This report concludes that China is not a country with low labor standards, as is widely accepted.展开更多

After stationarity is verified by ADF (Augmented Dickey-Fuller) test, the power spectrum of the data exhibits a power law decay as a whole characterized by 1/f^β processes with possible long range correlations. Subsequently, by using the method of detrended fluctuation analysis (DFA) of the general volatility in the stock markets, we find that the long-range correlations are occurred among the return series and the crossover phenomena exhibit in the results obviously.Further, Shanghai stock market shows long-range correlations in short time scale and shows short-range correlations in long time scale. Whereas, for Japan stock market, the data behaves oppositely absolutely. Last, we compare the varying of scale exponent in large volatility between two stock markets. All results obtained may indicate the possibility of characteristic of multifractal scaling behavior of the financial markets.展开更多

To achieve the objectives of the study, we collected data from all 15 banks listed on the Amman Stock Exchange for the year ending December 2013. The findings of the study suggest that there is strong compliance with respect to mandatory risk disclosure, as required by IFRS. However, the results generally signal a need for further improvement in the voluntary risk disclosure area, since most of the banks do not provide adequate information that can be of use to stakeholders. We also suggest future avenues of research into the topic to determine progress.展开更多

To achieve these objectives, a questionnaire was developed and distributed to respondents from audit firms in Bahrain. Descriptive statistics were used to analyse the influence of auditor-client association upon quality of audit and auditor independence and how audit quality and auditor independence are improved was also explored in the study. The results show that all the questions (1-8) in the questionnaire impair both audit quality and auditor independence with the means ranging from 3.6000 to 4.0364 with an average mean of 3.7212. According to the measurement scale, any item with a mean of 3.50 or more is acceptable, and since all the influences are above 3.50, they are all acceptable. Regarding how auditor-client relationship (or long tenured auditor) would improve both quality of audit and auditor independence, the results show that all the questions (9-17) would improve both audit quality and auditor independence with the means ranging from 3.6364 to 4.0727 with an average of 3.8646, which are acceptable. These results confirm statistically that there is a significant relationship between the auditor long-term tenure and audit quality and auditor independence, so the null hypothesis (H0) is rejected and the alternative hypothesis is accepted. Simple regression analysis is employed to test the hypothesis of the study and its significance. The results show that (H0) hypothesis is not significant. Therefore, the alternative hypothesis (H1) is significant at p 〈 0.005, which means that there are differences in viewpoints among respondents and the p-value obtained is 0.044 which is less than the significant value of p 〈 0.05. These results confirm the hypothesis that a significant relationship exists between the auditor long-term tenure and quality of audit and auditor independence.展开更多

The test section was a 7-element bundle installed in a hexagonal flow channel with three grid spacers. Data was collected at pressures of approximately 4.65 MPa for several different combinations of wall and bulk-fluid temperatures that were below, at, or above pseudocritical conditions. Analysis of the data has confirmed that there are three distinct heat-transfer regimes for forced convention in supercritical fluids: (1) normal heat transfer, (2) deteriorated heat transfer, and (3) enhanced heat transfer. It was also confirmed that the effects of spacers are evident which was previously observed in sub-critical experimental data. This work compares the wall and bulk fluid temperature data of the experiments to predictions based upon current 1-D correlations for heat transfer in supercritical fluids.展开更多

The aim of this study is to investigate the family variables, including domicile, parents' education, their age, the type of work they do, family size, and family income. As to the social responsibility's dimensions for sample selected for this study; hence, it includes personal, ethical, national, environmental, health, and social responsibility. The current study adopted the descriptive approach along with a demographic data form and the social responsibility's scale. The sample selected consisted of 330 female students from various colleges within King Abdulaziz University. The results indicated that there was an impact on all the variables, thus such impact was in favor of those living in rural areas as to the ethical dimension and in favor of urban people as to the dimensions of accountability, parents' level of education, parents' seniority, working mothers, greater family size, and higher income.展开更多

To achieve these objectives, a questionnaire was developed and distributed to respondents that consist of all auditors working in audit firms in Bahrain. The findings indicated that there is a significant relationship between mandatory audit firm rotation and quality of audit. The study also indicated that longer partner tenure makes the auditor's performance lack the quality in the auditing process. The average mean for all questions of the hypothesis together is 2.73 with average standard deviation of 0.94 which is less than half of the mean. This means that there is no dispersion among respondents about the questions of the hypothesis. Also, the analysis shows that the t-value is 29.922, which is greater than the table critical value of t (1.66), and the p-value obtained is 0.000 which is less than the value of significance at p 〈 0.05. These results confirm statistically that there is a significant relationship, so the null hypothesis is rejected and the alternative hypothesis is accepted.展开更多

Previous archival research on the value relevance of FCTAs has documented a weak or non-existent link between FCTAs and firm valuation (Pinto, 2005). The hypothesized reasons could reside in the econometric method employed, in the use of as-if numbers, and in the missing consideration of the differential effect that exchange rate changes have on firms of varying levels of capital intensiveness. This study adds to the existing literature by empirically testing the value relevance of as-reported FCTAs numbers in the earnings and book value model the Ohlson-like interacted model through panel data techniques. The main finding of this study is that as-reported FCTAs are significantly and incrementally value-relevant, when their parameter estimates are allowed to vary in the cross-section.展开更多

The paper gives emphasis to the domain of technical analysis. In the broader sense the technical analysis enables the dynamics of the expected future values of the shares estimation. This can be performed on the basis of the data on historical trends of the revenues, profits and other indicators from the balance sheet, but also on the basis of historical data on changes in the values of the shares. Companies generally belong to the different sectors that have different presumptions of development resulting from the global market trends, technology and other characteristic. Processing of historical data values of the outstanding shares of the Zagreb Stock Exchange (ZSE) is origination of this research. Investors are interested to know the estimation of future returns for the stocks as well as the size of the risk associated with the expected returns. Research task in this paper is finding the optimal portfolio at the ZSE based on the concept of dominant portfolio by Markowitz approach. The portfolio is created by solving non-linear programming problem using the common software tools. The results of obtained optimal portfolios contain relevant conclusions about the specifics of the shares as well as the characteristics of the industrial sectors but also provide a further knowledge about diverse sectors treatment at the stock exchange in a multi-year period.展开更多

One hundred and fifteen respondents, consisting of 67 female executives and 48 male subordinates, were purposively selected. Both quantitative and qualitative data were utilized. Female executives perceived and experienced three out of the 11 acts-male subordinates grabbing their groins before female executives, male subordinates bragging about their sexual organs as hefty before female executives, and male subordinates bragging about their prowess in bed before female executives-as most sexually harassing And 35~6 of the male respondents reported that they grabbed their groins before female executives, 60.4% bragged of the size of their sexual organs, and 52.1% bragged of their prowess in bed. The focused group discussions (FGDs) revealed that CPSH may induce low job satisfaction, job commitment and reduced productivity, increase feelings of loss of control over the body, destroy gender identity, and increase the tendency to quit the job. Female executives ignored the acts and maintained strict formal relationships with their male subordinates as ways of coping with the acts. Conclusively, as powerful as female executives are in position of authority, they are still powerless as regards CPHS.展开更多

Aside from considerations re- garding the biological consequences of these campaigns, we argue that when society rejects all values of science and expertise then only badly supported and negligent decisions will be made about conservation and management issues. The extermination of small mammal species, some of which play crucial ecological roles in several regions of the world, is just an example of such discredit and misinformation. Without a strong commitment towards evidence-based policy-making, economic investments in re- search and development could be entirely compromised展开更多

Aside from considerations re- garding the biological consequences of these campaigns, we argue that when society rejects all values of science and expertise then only badly supported and negligent decisions will be made about conservation and management issues. The extermination of small mammal species, some of which play crucial ecological roles in several regions of the world, is just an example of such discredit and misinformation.
