A Comparison Of Delivery Formats To Encourage Student-Centered Learning In A Power Engineering Technology Course
Get PDFThis paper describes a student-centered approach to a power engineering technology course using the flipped or inverted classroom as well as active learning in the form of group discussions and team problem solving. The study compares student performance and perceptions of a traditional, teaching-centered classroom to two different flipped courses: one using video lectures and one using a media-enhanced electronic textbook. The authors compared courses in the areas of 1) student performance on multiple choice and numerical analysis problems, 2) students’ perceptions of course delivery format and satisfaction with the course and instructor, and 3) technical content coverage. Results show little difference in student achievement between the course formats, strong negative reactions by students to unfamiliar instructional methods, and little difference in content coverage. The authors believe that the outcomes of this study can be attributed to the benefits of small class sizes (n<12), which naturally enable active learning to be utilized without the need for rigid and formal course structure
Extreme Risk In Resource Indices And The Generalized Logistic Distribution
Get PDFThe resource sector accounts for a substantial proportion of market capitalization on the US and South African stock exchanges. Hence, severe movements in related stock prices can drastically affect the risk profile of the entire market. Extreme value theory provides a basis for evaluating and forecasting such sporadic occurrences. In this article, we compare performances of classical extreme value models against the recently suggested generalized logistic distribution, for estimating value-at-risk and expected shortfall in resource indices. Our results suggest a significant difference in risk behavior between the two markets and the generalized logistic distribution does not always outperform classical models, as previous work may have suggested
Audit Quality And Accrual Quality: Do Big 4 Auditors Indeed Enhance Accrual Quality Of ‘Powerful’ Clients?
Get PDFExternal auditors are considered ‘watchdogs’ which closely monitor corporate financial reporting process and provide guidelines for investors and financial institutions. However, recent accounting scandals in Korea indicate that external auditors may cater their audit reports to their clients’ needs. Based on a sample of listed companies on the Korea Stock Exchange from 2001 to 2010, this study finds the evidence consistent with such conjecture. First, large business conglomerates in Korea (so called ‘chaebols’) audited by Big 4 have lower accrual quality than the others, indicating that Big 4 auditors may not serve as watchdogs to enhance accrual quality of ‘powerful’ clients. However, powerful clients who pay greater non-audit service fees to Big 4 auditors have higher accrual quality than the others. This result suggests that non-audit services provided by Big 4 may not necessarily harm the quality of accounting information, contrary to the traditional view in the literature
Analysis On The Effect Of Express Checkouts In Retail Stores
Get PDFIn this study, we investigate the effect of having express checkout lanes in retail stores. Express checkout lanes are being used to reduce expected wait time of small-buying customers, but their operational effect has not been analyzed so far. By comparing the wait time and the queue length of the two scenarios (universal checkout lanes only and separated checkout lanes with express counters) via simulation, we have found that the average wait time of the separated checkout lanes may not be shorter than that of universal checkout lanes. This may be due to that the effect of pooling servers decreases as the number of servers being pooled at each checkout set decreases. The queue length of express checkout lanes may be shorter than that of universal checkout lanes, but in some cases, the average queue length of separated checkout lanes is longer than that of universal checkout lanes, probably due to the effect of pooling servers. By conducting a computational study, we have observed that the effect of pooling servers decreases with customer arrival rate, decreases with regular checkout duration, and slightly increases with regular checkout time variability. These results give us an insight on when the express checkout counters can be effective in retail service operations
The Role Of Religious Control In Dysfunctional Audit Behavior: An Empirical Study Of Auditors Of Public Accounting Firm In Indonesia
Get PDFThis study is an empirical study of dysfunctional audit behavior in public accounting firm in Indonesia. The objective of this study is to analyze the influence of external locus of control and professional commitment on the dysfunctional audit behavior moderated by religious control. The sample of this study is 397 accountants, working in public accounting office in Indonesia, consisting of junior accountants, senior accountants and accountant managers. The sample is selected using accidental non-random sampling. The data is in the form of emails sent to the respondents. The data is analyzed using absolute difference of moderated regression SPSS. This study employs value theory approach, especially religious value in solving problems. The result of the study shows that partially, external locus of control, professional commitment, and religious control decrease dysfunctional audit behavior. In addition, this research reveals that religious control moderates the influence of professional commitment on dysfunctional audit behavior. However, religious control is not able to moderate external locus of control in decreasing dysfunctional audit behavior
Investment Efficiency Between Listed And Unlisted Firms, And Big 4 Audit Firms’ Effect: Evidence From Korea
Get PDFWe examine the difference in investment efficiency between listed and unlisted firms and the effects of auditing by Big 4 audit firms on the investment efficiency of firms. Generally, listed firms are large in size, have a high level of stakeholders’ demands on the firm information, and show large ripple effects of managers’ decision making. Listed firms have a demand hypothesis that they are motivated to provide high quality accounting information and an opportunistic behavior hypothesis that they are more motivated to make opportunistic financial reporting to meet the expectations of capital markets compared to unlisted firms. Consistent with previous study (Chen, Hope, Li & Wang, 2011), this study measures investment efficiency using the investment forecasting model as a growth opportunity function. The results of the study, in the analysis of full samples, the listed firms have significantly higher investment efficiency than the unlisted ones. In the over-investment samples, it is found that the listed firms have higher investment efficiency. On the contrary, in the under-investment samples, indicate it is found that the unlisted firms have higher investment efficiency. Finally, it is found that listed firms audited by Big 4 audit firms have the higher investment efficiency. This study contributes to the literature on investment efficiency of listed and unlisted firms. Finally, it is expected that it will provide useful information on investment efficiency by expanding the scope of research and making the measurement of variables more precise
Mandatory Adoption Of IFRS And Earnings Transparency In Korea
Get PDFWe investigate the relation between mandatory adoption of IFRS (International Financial Reporting Standards) and earnings transparency in Korea. We define transparency of earnings as how well it explains a firm value. Financial reporting mitigates information risks of the firm by lessening information asymmetry between insiders and outsiders of a firm. If accounting information produced after adopting IFRS better explains a firm value, then, it will reduce information asymmetry and information risks of the firm, resulting in enhancement of earnings transparency. We measure earnings transparency based on Barth, Konchitchki, and Landsman et al. (2013) and Cheng and Subramanyam (2008).
The sample is 2,276 which are listed on Korea stock exchange over 2008-2014. The empirical result shows adopting IFRS is significantly positive with earnings transparency, which means it mitigates information asymmetry, enhancing earnings transparency in Korea.
Our study is distinguished from prior studies because we empirically examine influence of adopting IFRS on earnings transparency of Korea. Our result implies adopting IFRS contributes to higher earnings transparency which helps market participants make decisions
Effect Of Changes In The Korean Accounting Environment On The Productivity Of Accounting Firms
Get PDFTo investigate how changes in the accounting environment in Korea affect firm productivity, this study analyzes productivity by firm size and labor type from 2000 to 2014, using a Cobb–Douglas production function. We find that (1) the greater the management advisory (tax) revenue, the greater the total revenue in large (small) accounting firms; and (2) marginal revenue is greatest for partners, followed by certified public accountants and general employees. In particular, partners’ contribution to large accounting firms improved after 2007, whereas general employees made a significant positive contribution to total revenue before 2007
Factors That Affect The Nonpayment Of Municipal Services In Madibeng, Mamelodi And Soshanguve Townships Of South Africa
Get PDFThe study was conducted in Madibeng, Mamelodi and Soshanguve townships of South Africa in order to assess and evaluate the main reasons for the non-payment of municipal services by members of the community. The study was conducted based on a stratified random sample of size 428 households. Statistical data analyses were performed by using methods such as ordered logistic regression analysis and Bayesian analyses. The results showed that 22% of households in Madibeng, 54% of households in Mamelodi and 78% of households in Soshanguve were willing to pay for municipal services that were provided to them by their local municipalities. Reluctance to pay for municipal services was significantly influenced by employment status, level of formal education and race group. 
Faraday’s Principle And Air Travel In The Introductory Labs
Get PDFWe all know that we must improve the quality of teaching in science at all levels. Not only physicists but also many students from other areas of study take the introductory physics courses in college. Physics introductory laboratories (labs) can be one of the best tools to help these students understand applications of scientific principles that affect our lives. However, traditional labs are considered by many students, especially non-physics majors, as uninteresting due to the lack of real life applications. In this study, we develop a lab experiment that uses air travel to understand one of the most important concepts in physics: the induced voltage per Faraday’s law.
