Analysis Of Technology Skill Requirements For Entry-Level Accountants, Jiane Louella Tolentino Rabara Jan 2025

Analysis Of Technology Skill Requirements For Entry-Level Accountants, Jiane Louella Tolentino Rabara

Theses and Dissertations

This study examines the evolving impact of emerging technologies on skill requirements for entry-level accountants. Using a mixed-method approach that combines literature review and quantitative analysis of 2,257,082 job postings from 2021 to 2024 provided by the Butler Center for Research and Economic Development, the study evaluates trends in employer expectations across firm sizes and time. Chi-square tests revealed significant changes in the proportion of postings requiring technological skills (χ² = 117,672, df = 3, p < .001), indicating a shift in how technology-related competencies are presented in job ads. Specifically, while previous job postings often included general technical skills alongside traditional accounting tasks, recent job postings increasingly emphasize advanced or specialized technologies—such as ERP systems, cloud accounting platforms, and automation tools. This shift suggests that employers are moving away from broad technical expectations toward more targeted skill sets, reflecting the evolving technological demands of the profession. A separate chi-square test found a significant relationship between technological skill requirements and job ad duration (χ² = 2,309.57, df = 4, p < .001). However, no consistent pattern of longer posting duration was observed for technology-oriented roles. Literature-based synthesis further showed that large accounting firms continue to demand more advanced technological competencies than smaller firms. Overall, while traditional accounting skills remain predominant, the findings indicate a transition toward more specialized technological expectations in the entry-level accounting role.

Technologies Of Violence: Law, Markets, And Innovation For Gun Safety, Joseph Blocher, Christopher Buccafusco Jan 2025

Technologies Of Violence: Law, Markets, And Innovation For Gun Safety, Joseph Blocher, Christopher Buccafusco

Faculty Scholarship

Violence in the United States is distinctive in many ways, perhaps none more visceral and fundamental than the technologies with which it is practiced. American violence disproportionately involves guns, and because guns are such an effective tool of violence, confrontations involving them are disproportionately deadly. Decades of research confirm this "instrumentality effect, " and it is reflected in the broad, bipartisan agreement that the nation has a gun violence problem. The deep disagreement, of course, remains about how to address it, with most of the debate focused on regulating who can carry which guns, where, and how.

But fully understanding, …

A Conceptual View Of Data For Decision-Oriented Databases: A Knowledge-Driven Approach, Sung-Kwan Kim, Wenjun Wang, Seunghyun Kim Jan 2025

A Conceptual View Of Data For Decision-Oriented Databases: A Knowledge-Driven Approach, Sung-Kwan Kim, Wenjun Wang, Seunghyun Kim

Journal of International Technology and Information Management

Typical database design goes through three levels of data modeling: conceptual modeling, logical modeling, and physical modeling. In particular, conceptual modeling is important since it captures and documents user data requirements. Conceptual modeling serves as a blueprint for designing a database by defining information content to be included in a database. Presently, decision-oriented databases have no well-accepted conceptual modeling approach to apply. While some use conceptual modeling approaches for transaction-oriented databases such as the ER (Entity-Relationship) model, they are not well-suited for decision-oriented databases. It is hard to map from the ER Model to decision-oriented data models. Others attempt to …
