Towards an understanding of excel functional skills needed for a career in public accounting: Perceptions from public accountants and accounting students

Public accounting firms (e.g., Grant Thornton, 2012) are stressing an interest in recruiting accounting students with a proficiency in Excel. The purpose of this study is to investigate which Excel functions are perceived to be important and useful for new hires to understand prior to starting a job in public accounting. We collect survey data from four large public accounting firms as well as undergraduate and graduate accounting students (i.e., potential new hires) to gauge perceptions of Excel importance, knowledge, and usage in public accounting. We find that employees at the firms believe the most important Excel functions are: basic formula, filter and sort data, vertical (horizontal) lookup, formatting of documents, and If/Then statements. In a comparison of new hires at public accounting firms with accounting students, results suggest that accounting students underestimate the importance and usage of some of these Excel functions. In addition, results suggest that new hires’ perceived knowledge on how to use specific Excel functions in their accounting job is statistically different than students’ perceived knowledge on how to use some of the same Excel functions. Our research contributes to educational accounting literature by documenting which Excel functions employers in public accounting want new hires to know prior to starting a job in public accounting. Also, this research informs accounting educators that students’ perceptions are not the same as public accounting employers’ expectations with respect to analytical skills using Excel technology.     

Application of early risk detection concepts and methods to environmental health. A German feasibility study

Early risk detection is essential for being able to address the most important environmental health risk‐topics in a persistent and prospective manner. In support of the action programme “Environment and Health” (APUG) of the German Federal Ministry of Health and Social Security (BMGS) and the Federal Ministry for the Environment, Nature Conservation, and Nuclear Safety (BMU) which recommended that a detection and evaluation system for the timely recognition of emerging risk problems be developed, a qualitative feasibility study was commissioned. The results of this study are presented here and support the development of an early risk detection system based on the insights gained from the investigation of case studies and the differentiation and presentation of a risk typology, methods, tools, and suggested organizational processes.

The study has shown that early risk detection includes the identification, characterization, evaluation and dissemination of information on possible risks as well as the circumstances of appearance and distribution. The goal is the recognition of possible risks in order for risk management to be able to introduce swift and appropriate measures. Consequently, it can also serve as an instrument towards further development of a balanced and structured implementation of the precautionary principle in the environmental health policy.     

Statistical Thinking in Empirical Enquiry

This paper discusses the thought processes involved in statistical problem solving in the broad sense from problem formulation to conclusions. It draws on the literature and in-depth interviews with statistics students and practising statisticians aimed at uncovering their statistical reasoning processes. From these interviews, a four-dimensional framework has been identified for statistical thinking in empirical enquiry. It includes an investigative cycle, an interrogative cycle, types of thinking and dispositions. We have begun to characterise these processes through models that can be used as a basis for thinking tools or frameworks for the enhancement of problem-solving. Tools of this form would complement the mathematical models used in analysis and address areas of the process of statistical investigation that the mathematical models do not, particularly areas requiring the synthesis of problem-contextual and statistical understanding. The central element of published definitions of statistical thinking is "variation". We further discuss the role of variation in the statistical conception of real-world problems, including the search for causes.
