Abstract
Purpose
In continuous improvement (CI) projects, cause-and-effect diagrams are used to qualitatively express the relationship between a given problem and its root causes. However, when data collection activities are limited, and advanced statistical analyses are not possible, practitioners need to understand causal relationships. The paper aims to discuss these issues.
Design/methodology/approach
In this research, the authors present a framework that combines cause-and-effect diagrams with Bayesian belief networks (BBNs) to estimate causal relationships in instances where formal data collection/analysis activities are too costly or impractical. Specifically, the authors use cause-and-effect diagrams to create causal networks, and leverage elicitation methods to estimate the likelihood of risk scenarios by means of computer-based simulation.
Findings
This framework enables CI practitioners to leverage qualitative data and expertise to conduct in-depth statistical analysis in the event that data collection activities cannot be fully executed. Furthermore, this allows CI practitioners to identify critical root causes of a given problem under investigation before generating solutions.
Originality/value
This is the first framework that translates qualitative insights from a cause-and-effect diagram into a closed-form relationship between inputs and outputs by means of BBN models, simulation and regression.

Abstract
As part of the portable product interconnects characterisation programme, the present investigation was conducted to determine the attachment integrity and long‐term reliability of Thin small Outline package (TSOP) solder joints. Accelerated thermal cycling combined with analytical modelling was used to evaluate the reliability for credit card sized DRAM memory cards. The measured solder joint fatigue lifetimes varied from 645 to 830 thermal cycles for TSOP‐II and I components, respectively. The modelling results corroborated the empirical findings. The solder joint thermal fatigue data were used to predict the card reliability under operating field conditions. The cards were found to be reliable for their intended use environment.

Abstract
Purpose
The purpose of this paper is to describe a case study used in a strategic sales class that employs the use of work-based learning pedagogy to expose students to real-life cold calling experiences. This real-life cold calling experience involves students within the course building a target list of prospective students for a small liberal arts college. The students must then construct pre-call strategies, build rapport with prospective students and finally “close the deal” by having the prospective student visit campus.
Design/methodology/approach
This paper begins by describing work-based learning as a unique pedagogical method and the importance of cold-calling skills in the context of workplace skills in demand. Theoretical foundations in Lichtenstein and Lyon’s (1996) entrepreneurial skillset is analyzed, as is the application of “live” group projects. The case is then described in detail and focuses on the project itself, the personal and group incentives used in the course of the project, and finally, a review of the learning outcomes and desired skillset outcomes for the class.
Findings
The case shows that students can learn and implement the behaviors, attitudes and practices that make professional cold-callers successful. The impact on the university can also be seen since real contributions were made to the recruiting efforts of the college vis-à-vis higher matriculation numbers. The entrepreneurial skillsets and “live” group project literature is contextualized in light of the findings of the project. This research found that students engaged in varying levels of progress in their managerial, entrepreneurial, technical skillsets as well as levels of personal maturity. Finally, the authors provide guidance for future research to expound the findings of this project by testing the variables using quantitative methodologies.
Originality/value
The paper showcases an innovative pedagogic approach to exposing students to the best practices of cold-calling and allows them to exercise these tools real time as they make actual cold calls and work toward sales incentives. The focus on recruiting new students as customers of the college serves is not only active classroom learning, but it also serves mission-based outcomes to help the college achieve desired recruiting goals. This case study will provide a tool for small, liberal arts colleges to use which mobilizes faculty and students in the effort to recruit new students, in an environment where enrollment numbers are falling for this market sector in higher education.

Abstract
This research provides accounting-ethics authors and administrators with a benchmark for accounting-ethics research. While Bernardi and Bean (2010) considered publications in business-ethics and accounting’s top-40 journals this study considers research in eight accounting-ethics and public-interest journals, as well as, 34 business-ethics journals. We analyzed the contents of our 42 journals for the 25-year period between 1991 through 2015. This research documents the continued growth (Bernardi & Bean, 2007) of accounting-ethics research in both accounting-ethics and business-ethics journals. We provide data on the top-10 ethics authors in each doctoral year group, the top-50 ethics authors over the most recent 10, 20, and 25 years, and a distribution among ethics scholars for these periods. For the 25-year timeframe, our data indicate that only 665 (274) of the 5,125 accounting PhDs/DBAs (13.0% and 5.4% respectively) in Canada and the United States had authored or co-authored one (more than one) ethics article.

Abstract
Purpose
Other business education literature, particularly in the field of economics, has developed theories in respect of the reasons for non‐attendance of lectures and the positive correlation between class attendance and academic performance. The aim of this paper is to determine the generalizability of these theories to a large accounting class in South Africa.
Design/methodology/approach
This paper is a differentiated replication of the study by Paisey and Paisey, who provided initial evidence of the generalizability of these theories to a small accounting class in Scotland, employing a research questionnaire and the analysis of quantitative and qualitative data.
Findings
The reasons given for the non‐attendance of lectures generally correspond with those previously reported. Certain differences that are identified are likely a result of specific country or economic factors. This study found a significant positive correlation between class attendance and academic performance; however, the correlation is low and not very meaningful. Further analysis reveals some difference between language groups suggesting that culture and ethnicity may have an effect on the relationship between class attendance and academic performance.
Originality/value
This paper raises questions as to the generalizability of prior research on class attendance and academic performance. The findings of this study suggest other factors, including students' economic, cultural and ethnic backgrounds, are likely to affect associations between class attendance and academic performance.

Abstract
The study investigated the relevance of psychosocial variables and how they interact with socio economic status (SES) as it relates to the persistence of African-American students at the major US public universities. The study analyzed the responses of 327 web survey participants attending a major public university in the eastern region of the United States. The results suggest that students from higher SES backgrounds, more than likely, have already acquired or are more easily able to adopt characteristics that are ideal for persistence (e.g., commitment to personal goals, and biculturalism) than students from lower SES backgrounds.
Previous studies have shown that – even after controlling for precollege performance – students who come from families with higher-income levels and parental education persist to graduate at higher rates and earn higher-grade point averages (Bowen & Bok, 1998; Pascarella, 1985). This study purports to provide the context for reflecting on the ways in which current student persistence theories might be modified to account more directly for how SES may influence psychosocial variables that contribute to the process of African-American student persistence in major US universities.

Abstract
That the introduction of the Control system should have given rise to a considerable amount of criticism, both appreciative and adverse, was naturally to be expected. The appreciative remarks which have appeared in the press, and those also which have been privately communicated to the directors, indicate that the subject has been intelligently considered, and in some cases carefully investigated and studied. The opinions given are worth having on account of the position and influence of hose who have given them, and on account of the obvious freedom from bias which has characterised them. This is so far satisfactory, and goes to show that the success which has attended the working of the Control system abroad may well be expected to attend it in this country as soon as it is sufficiently well known to be appreciated by the manufacturers and vendors of good and genuine products, and by the general public, whose best interests it cannot but serve.
