Students use data analytics to evaluate fictitious online sales data and explore sales tax nexus standards following South Dakota v. Wayfair, Inc. ( Wayfair). This case provides instructors flexibility. Students can use Tableau to create visualizations that identify states with sales satisfying nexus standards, applying the Wayfair or multistate standards. Students can use Robotics Process Automation to evaluate whether the company established nexus in a particular state. Instructors can include no tax research or select from several pertinent tax research questions. This case can be used in undergraduate or graduate tax, audit, or AIS courses, from compliance or tax risk perspectives. The learning objectives are to develop students’: (1) knowledge of data analytics; (2) knowledge of economic nexus and assess the tax law changes impact on business decisions; (3) research skills; (4) skills specific to data analytics and data visualization in accounting; and (5) effective oral and written communication skills.

The purpose of this teaching note is to explain how Structured Query Language (SQL) queries can help auditors to independently retrieve properly formatted data as audit evidence or for further analyses. The note demonstrates data extraction using Microsoft (MS) Access, one of the simplest SQL compliant database software applications. We use a dataset fragment extracted from the publicly available enterprise datasets provided by Walton College (University of Arkansas) to run SQL queries as a part of audit investigations. Data extraction is the first step of Extract, Transform, and Load (ETL) and may be time-consuming. We demonstrate how SQL queries can assist with this task, thereby allowing the auditor to begin analysis sooner. This teaching note can be used to prepare future auditors for the emerging data-rich and technology-driven business environment.

This study explores the implications of market digital transformation in the United Arab Emirates (UAE) for the undergraduate accounting curriculum. Responding to a number of government initiatives towards artificial intelligence (AI) transformation, corporations and government agencies in the UAE have recently started to test and adopt AI, Blockchain Technology (BT) and Data Analytics (DA) in their operations. This digital transformation in the business environment raises concerns as to whether existing accounting curricula are preparing accounting graduates for the emerging IT needs relevant to the existing accounting job market. To this end, this study explores the extent to which the current accounting curriculum in the UAE reflects the current digital transformation in the country.

The Novel Coronavirus Disease, COVID-19, has been declared a worldwide pandemic by the World Health Organization (WHO) on March 11, 2020 (WHO 2020). Scientists in different fields have contributing to study the pandemic development and to provide support to government policies. However, the traditional measures of individual health, population health, and policy effects have been criticized that many of them reflected the pandemic inaccurately and untimely. This study evaluates the pandemic circumstances from the auditor's perspective, applies the system dynamics theory, and proposes dynamic models to understand the ongoing pandemic using business measurements and analytical technologies. This study also works on estimations of the feedback effects of pandemic-related policy measures. The deliverables of this study establish a dynamic view to understand the current pandemic and provide the government with a simulation tool to visualize the impacts of government interventions at different levels.

The present study introduces an assessment that includes multiple measures of language and discourse within the theoretical frameworks of comprehension in education and cognitive science. We utilize an automated textual assessment tool, Coh-Metrix, to analyze the Management Discussion and Analysis (MD&A) sections of annual reports to determine if significant differences in text readability are present between bankrupt and nonbankrupt companies. When applying Coh-Metrix indices, the MD&A sections of nonbankrupt companies appear to be easier to understand in terms of word concreteness, referential and deep (or causal) cohesion, and syntactic simplicity. More specifically, the MD&A sections of nonbankrupt companies contain more concrete wording, simpler syntactic structures, more word co-references to tie words and ideas, and more causal and intentional connectives to establish causal and logical relationships within the text.

We explore the connections from phenomena to new data and from data to theories. While starting with philosophical perspectives from positive economic theory to positive accounting theory, we emphasize the relevance and importance of new data sources to archival research in accounting and the implications to research in accounting information systems and emerging technologies. We present a number of studies in accounting that exemplify the critical role of data in the discovery of theories from phenomena. We argue that data in conventional empirical studies limit methodology to require assumptions and complex econometric treatments for general business settings. Therefore, recent development in "big data" and data analytics, particularly, the improved data availability from a variety of new sources have made strong research designs possible. We provide evidence that 88% of the JIS and 100% of the JETA empirical archival publications in the recent two years used new data sources.

Comparative analysis commands special attention in financial analysis as it not only facilitates understanding of year-on-year changes but also of trends in the performance and position of a company. It is often a go-to tool for competitor analysis. In this note, I illustrate the use of R (software), its allied packages, and textual analysis algorithms to extend the use of comparative analysis to ‘unstructured’ information presented in the MD&A section of annual reports. For this use case, I consider two giant tech rivals, Apple and Amazon, and present a comparative analysis of their MD&A section using Cosine and Jaccard similarity measures. I also compare the most important words based on tf-idf and sentiments for each company and across the two companies. When supplemented with financial information, comparative analysis can offer novel insights for analysts, managers, researchers, and academics and is a valuable tool to include in accounting curricula.

Requirement of G4 standards as common practice in sustainability reporting makes it important to understand the readability of such reports. This study contributes to the extant body of literature by assessing the readability of sustainability reports. We investigate several factors such as company size, company age, complexity, domestic versus international, and audited versus unaudited reports and how they contribute to the readability of sustainability reports. We apply text analytics to U.S. and Global firm issued sustainability reports. We also provide evidence about factors that may contribute to the readability of sustainability reports. We find that reports of companies in regulated industries are less readable than other firms' reports. We also find that less complex firms have more readable sustainability reports. This study should provide some insights to users of sustainability reports, standard setters for reporting standards, and for future researchers.

We describe a characterization of the conceptual and emotional changes on environmental issues in a sample of firms certified under the ISO 14001 standard. Business communications regarding the main Spanish industrial firms have been downloaded from the ABI/INFORM database and processed using Vantage Point software, in order to study the evolution of the main concepts and emotions before and after the certification year. Our study concludes that in the years before certification environmental management was fundamentally tied to operative issues, broadly pivoting on the immediate impact of a firm's productive activities. Environmental management gains strategic traction in the years after certification, positioning itself near corporate decision-making concepts and associated with adjectives that denote relevance and positivity. The sentiment analysis points at an increased positivity of environment-related issues, accompanied by a general decrease in negative emotions and an increased presence of expectation and planning emotions.

Organizations such as the AASCB and the Pathways Commission (2012) recommend that emerging technologies be included in the accounting curriculum. Yet the inclusion of emerging technologies represents a challenge for accounting educators due to the complexity and uncertainty associated with many technologies, as well as the rapid pace of technology change and innovation. This paper answers the call by the Pathway Commission (2012) for additional research focused on enhancing learning experiences to better reflect current and emerging technologies. Using an experiential learning approach (Butler, Church, and Spencer (2019), we create a hands-on, learning activity focused on blockchains in order for accounting students to gain a conceptual understanding of blockchains and its applications and implications beyond bitcoins.
