The Optimum Way to a CPA
The accounting profession has established the 150 semester hours of education requirement for Certified Public Accountants (CPAs) in all jurisdictions of the United States (except the US Virgin Islands. However, the requirement does not specify how the extra education should be earned. The purpose of this study is to recommend a course of action in the accounting curriculum to address the extra 30 semester hours above the typical 120 semester hours baccalaureate degree to meet the education requirements for the CPA, based on the quality of new accounting professionals as perceived by hiring CPAs. A survey using a Likert-type scale was administered to measure hiring CPAs perceptions of new accounting professionals’ quality. The findings suggest the desire for new hires to have more study in general business and financial accounting, both at the undergraduate and graduate levels. This research provides insight into how the accounting student can best prepare themselves for a successful career in accounting and how the profession can draw effective new entrants
Lean Accounting, Fat Problem? A Critical Analysis of Lean Accounting’s Value
Lean accounting is an accounting system that is designed specifically to facilitate the application of lean manufacturing. It is considered a new tool among the various accounting methods available to management. As a managerial accounting method, the purpose of lean accounting should be to provide valuable, insightful information to management for decision-making. However, lean accounting sometimes fails to serve this ultimate purpose as a managerial accounting alternative. We conduct a case study of Toyota to examine lean accounting’s value. The analysis shows that lean accounting tends to be short-term focused, which may jeopardize a company’s long-term growth prospective. Lean accounting is also incapable of providing accurate product cost information, and therefore is unable to support a strategic decision-making process. Traditional standard costing and activity-based costing may be superior to lean accounting for long-term planning and decision-making. The potential exists for a dual system with lean accounting for tactical short-term information and either standard costing or activity-based costing for strategic long-term information

Intangible Assets Valuation in the Hospitality Industry
In publicly traded firms, there is usually a discrepancy between the market value and the book value of the firm, often due to the valuation of intangible assets. Understanding this discrepancy is import- ant for investors, especially in the service industries like hospitality, where there is considerable industry disruption and consolidation. In this study we examine the effect of four intangible asset investments—research and development (R&D), training, advertising, and pension—on the market premium of restaurant firms. Using a longitudinal sample of 1,421 firm-year observations, the results of our analyses show that R&D, training, advertising, and pension are all important valuation con- structs in the hospitality industry, and their effects on market premium vary by restaurant type. This study fills the gap in the current literature by providing a quantitative method to value intangible assets in the hospitality industry. The practical implications of this study will provide managers in the hospitality industry with helpful insights for strategic decision making, specifically regarding R&D, advertising, and employee compensation
Business Education of CEO-CFO and Annual Report Readability
Financial report readability captures the transparency and effectiveness of information communicated by firms’ executives. It’s interesting to investigate whether business knowledge, cognitive preferences, and professional ethics taught by a business education will shape the CEO/ CFO’s thinking in determining words, languages, paragraphs, and contents presented in financial reports when the self-interested CEO/CFO tends to influence the interpretation of financial information users. Using a sample of S&P 1500 CEOs and CFOs, we find that the CEO (CFO) with a business degree is associated with better (worse) readability of annual reports and the positive (negative) relation is strengthened (moderated) by internal corporate governance and external analyst following. Furthermore, we explore the interaction between CEO’s and CFO’s education background and provide additional evidence for the conflict of interest between CEOs and CFOs on financial reporting strategies. Our findings suggest business education, although has no direct impact on financial reporting quality, is beneficial to CEOs for strengthening their monitoring role in firm’s financial reporting activities. Also, we consider that the ethical topics in business education can enhance financial executives’ awareness to conduct practice under the ethical codes. Our study has implications for academic literature, business education, industry practitioners, and standards setting
Simulation of chemical reaction dynamics on an NMR quantum computer
Quantum simulation can beat current classical computers with minimally a few
tens of qubits and will likely become the first practical use of a quantum
computer. One promising application of quantum simulation is to attack
challenging quantum chemistry problems. Here we report an experimental
demonstration that a small nuclear-magnetic-resonance (NMR) quantum computer is
already able to simulate the dynamics of a prototype chemical reaction. The
experimental results agree well with classical simulations. We conclude that
the quantum simulation of chemical reaction dynamics not computable on current
classical computers is feasible in the near future.Comment: 37 pages, 7 figure
The Indoor Thermal Environment Simulation and Testing Validation of a Power Plant Turbine Room in Extreme Cold Area
AbstractThis paper conducts an analysis study on indoor thermal environment of a steam turbine room in power plant by CFD. Refer to a typical steam turbine room in an actual thermal power plant which has been conducted field test, the typical numerical simulation model is built including a reasonable indoor heat conditions, structural parameters and envelope architectural opening, flow boundary conditions. Indoor air temperature distribution and air velocity distribution of steam turbine room is obtained. Comparing the simulation results with the corresponding field measurement data on typical location show that two sets of results are very close. So accuracy and applicability of CFD simulations is proved. It is also proved that complete method for CFD simulations of the paper is appropriate for interior thermal environment study of typical steam turbine room and thus laid the foundation for the further studies of a large number of universal cases
Atomic-scale observation of localized phonons at FeSe/SrTiO3 interface
In single unit-cell FeSe grown on SrTiO3, the superconductivity transition
temperature features a significant enhancement. Local phonon modes at the
interface associated with electron-phonon coupling may play an important role
in the interface-induced enhancement. However, such phonon modes have eluded
direct experimental observations. Indeed, the complicated atomic structure of
the interface brings challenges to obtain the accurate structure-phonon
relation knowledge from either experiment or theory, thus hindering our
understanding of the enhancement mechanism. Here, we achieve direct
characterizations of atomic structure and phonon modes at the FeSe/SrTiO3
interface with atomically resolved imaging and electron energy loss
spectroscopy in a scanning transmission electron microscope. We find several
phonon modes highly localized (~1.3 nm) at the unique double layer Ti-O
termination at the interface, one of which (~ 83 meV) engages in strong
interactions with the electrons in FeSe based on ab initio calculations. The
electron-phonon coupling strength for such a localized interface phonon with
short-range interactions is comparable to that of Fuchs-Kliewer (FK) phonon
mode with long-rang interactions. Thus, our atomic-scale study provides new
insights into understanding the origin of superconductivity enhancement at the
FeSe/SrTiO3 interface
Evaluation of the IP-10 mRNA release assay for diagnosis of TB in HIV-infected individuals
HIV-infected individuals are susceptible to Mycobacterium tuberculosis (M.tb) infection and are at high risk of developing active tuberculosis (TB). Interferon-gamma release assays (IGRAs) are auxiliary tools in the diagnosis of TB. However, the performance of IGRAs in HIV-infected individuals is suboptimal, which limits clinical application. Interferon-inducible protein 10 (IP-10) is an alternative biomarker for identifying M.tb infection due to its high expression after stimulation with M.tb antigens. However, whether IP-10 mRNA constitutes a target for the diagnosis of TB in HIV-infected individuals is unknown. Thus, we prospectively enrolled HIV-infected patients with suspected active TB from five hospitals between May 2021 and May 2022, and performed the IGRA test (QFT-GIT) alongside the IP-10 mRNA release assay on peripheral blood. Of the 216 participants, 152 TB patients and 48 non-TB patients with a conclusive diagnosis were included in the final analysis. The number of indeterminate results of IP-10 mRNA release assay (13/200, 6.5%) was significantly lower than that of the QFT-GIT test (42/200, 21.0%) (P = 0.000026). IP-10 mRNA release assay had a sensitivity of 65.3% (95%CI 55.9% – 73.8%) and a specificity of 74.2% (95%CI 55.4% – 88.1%), respectively; while the QFT-GIT test had a sensitivity of 43.2% (95%CI 34.1% – 52.7%) and a specificity of 87.1% (95%CI 70.2% – 96.4%), respectively. The sensitivity of the IP-10 mRNA release assay was significantly higher than that of QFT-GIT test (P = 0.00062), while no significant difference was detected between the specificities of these two tests (P = 0.198). The IP-10 mRNA release assay showed a lower dependence on CD4+ T cells than that of QFT-GIT test. This was evidenced by the fact that the QFT-GIT test had a higher number of indeterminate results and a lower sensitivity when the CD4+ T cells counts were decreased (P < 0.05), while no significant difference in the number of indeterminate results and sensitivity were observed for the IP-10 mRNA release assay among HIV-infected individuals with varied CD4+T cells counts (P > 0.05). Therefore, our study suggested that M.tb specific IP-10 mRNA is a better biomarker for diagnosis of TB in HIV-infected individuals
Principle of Duality in Cubic Smoothing Spline
Fitting a cubic smoothing spline is a typical smoothing method. This paper reveals a principle of duality in the penalized least squares regressions relating to the method. We also provide a number of results derived from them, some of which are illustrated by a real data example
