Rate constants (kd) of liquid drainage equation could be obtained from the above empirical equation. In this paper, the stability of the colloidal gas aphrons (CGAs), the effect of concentrations of sodium dodecyl benzene sulphate (SDBS), dodecyl trimethylammonium bromide (HTAB) and polyoxyethylene sorbitol anhydride monolaurate(Tween-20), temperature, stirring speed, stirring time, and various kinds of salts on the kd of liquid drainage are further investigated. The results show that the Arrhenius equation can be successfully used to describe the relation between kd arid absolute temperature (T), and concentrations of surfactants, stirring speed, stirring time and salinities also have great effect on the kd. At last, the CGAs drainage mechanism is explained from analysis of the rate of liquid drainage as a function of time.展开更多

Thus, does the ownership structure of a firm have an effect on the type of audit opinion it receives from CPA? This paper uses a sample including 1246 non-financial listed companies from China A-share market in 2003. Empirical results show: for listed firms, external auditor's propensity to qualify is lower with lower proportion of public shares, or with higher concentration of shares at a marginal significant level. However, the proportions of state-owned shares and institutional shares have no significant effects on audit opinions. A possible explanation is that the ownership structure influences risk awareness and negotiation power of audit firms, influences negotiation power of clients, and then ultimately influences auditors' reporting decision and audit opinions. The potential policy implication is: a more dispersed ownership structure and/or a higher proportion of public shares are preferable for higher audit reporting conservatism and audit quality in China.展开更多

The historical background of rating agencies including potential changes in the process of issuing their reports after the Dodd-Frank act is explored by the authors. CPAs (Certified Public Accountant) audit the financial statements of Securities and Exchange Commission [SEC] regulated issuers and are subject to the provisions of the Dodd-Frank act. Accountants may have new potential liabilities with clients that rely on credit agencies representations in financial statements. Analysis is made and conclusions are drawn on the effects of new credit rating agency responsibilities and that of auditors.展开更多

An investigation related to the top schools and AACSB accreditation is conducted as well as analyses related to public vs. private schools, area of the state where the institution is located, and University Systems. The results reflect impressive pass rates by University of Texas at Austin and Texas A&M University at College Station in terms of both number of students taking the exam and the percentage passing it. There was a significant CPA rate lead with private universities only when the two outstanding public universities were omitted from the analysis. The research also found significant differences in terms of areas of the state as well as university systems. The analysis and the findings are very important to students with CPA exam success as their academic primary goal with their university education, the educational institutions preparing the students, and society as a whole. The fmdings may help guide both the universities and the students to better success with the exam as well as perhaps help taxpayers and legislators know how well tax money is being spent in this area.展开更多

The majority of these HBCUs are located in the southeast section of the United States. HBCUs are a major supplier of certified public accountants (CPAs) to the profession. Therefore, the performance of candidates from HBCUs should be of interest to various constituents including educators, employers, parents, students, and other stakeholders. The purpose of this paper is to provide statistical performance on the 2011 CPA examination for large, middle, and small HBCUs based upon the number of testing events taken. Taking a testing event is not the same as passing a testing event. This was the dichotomy between quantity and quality of HBCUs' performances. For large HBCUs, Morehouse University, North Carolina Agricultural and Technical State University (NC A&T), and Tennessee State University (TSU) were cited. For middle HBCUs, Albany State University, Norfolk State University (NSU), and North Carolina Central University (NCCU) were cited. For small HBCUs, Alcorn State University, Fisk University, and University of Maryland Eastern Shore (UMES) were cited. The dichotomy between quantity and quality is real.展开更多

A reason given for this change was the supposed importance given to IFRS knowledge in the latest practice analysis. This paper examines this practice analysis as well as a review by graduate students of some accounting textbooks. The conclusion given by the students, other academic research and the practice analysis is that US is not prepared to immediately make this change.展开更多

We described a 35-year-old man who was found swelling in the left neck accidently, and no clinic evidences. A left total and right subtotal thyroidectomy and neck lymph nodes dissection were done. Lymph nodes metastasis was not shown. Postoperative of four months, computerized tomography scan liver showed multiple focal lesion. Microscopic examination showed that abundant melanin pigmentation was observed in many of tumor cells. Tumor cells were diffusely immunopositive for vimentin, CK, CgA, syn, CEA, Calcitonin, HMB45, S-100 and negative for TG, TTF-1. Melanotic medullary carcinoma is very rare. It is necessary to report more cases for exact biological behavior and prognosis.展开更多

Individuals choosing this profession have to complete a minimum 3-year internship program before becoming members of this profession. They have to pass an exam both to start and finish the internship program. The profession and the reasons for choosing it are highly significant issues. Therefore, the present study was conducted to investigate the factors directing the professional choices of prospective individuals who wish to be CPAFAs and the significance of such factors. Along with these objectives, a nation-wide study was conducted on candidates who took the CPAFA internship exam in periods of 2012-3, 2013-1, and 2013-2 (three periods). The factors affecting candidates' choices to be an accountant professional were gathered under five groups. The factors "influence of immediate surroundings", "prestigious social status of the profession", "high life-long income potential", "flexible working hours", and "future guarantee of the profession" had higher factor loadings than other factors.展开更多

Within the considered parameter space, we find that (a) the theoretical predictions for the BRs, CPAs and the polarization fractions in the SM and the mSUGRA model are all consistent with the currently available data within ±2σ errors; (b) For all the considered decays, the supersymmetric contributions in the mSUGRA model are very small, less than 7% numerically. It may be difficult to observe so small SUSY contributions even at LHC.展开更多

In the stock market, an independent audit is an important means to achieve fair presentation of financial statements by SFC-authorized accounting firm to conduct an independent audit of listed companies. In the open accounting services market, the independent audit is the most occupied audit resources, the most important business, and therefore the business is also subject to severe supervision of the SFC. Its value lies in perform forensic of the financial statements information of listed companies, and the higher the quality, the more it can reduce the risk of material misstatement of the financial statements, which is the need to strengthen and improve audit quality. Our independent audit market originated in the 1980s, along with the reform and opening up, China's economy is experiencing rapid growth, the demand for high quality audit increasingly enhanced. Audit activities have the nature of external and information asymmetry. External audit refers to it have an impact to investors, government departments and the other public stakeholders. Information asymmetry refers to the information asymmetry between the auditor and the audited entity, but due to the presence of asymmetric information and other reasons, the interests of stakeholders will be hurt by false information Government regulation as a model audit industry control, either in foreign or domestic, have played an irreplaceable role, especially in the socialism of China, plays a leading role. For example, when Enron bankruptcy United States speedly issue SOX in 2002 to strengthen the role of government regulation, effectively preventing the conspiracy of the CPA and the audited entity and improve audit quality. Visiblely, the role of government regulation in the audit market is very important.展开更多
