Several times in his IMechE/BP 1987 Tribology Paper — pages 4–11 of this issue — the author, Michael Monaghan, Technical Director of Ricardo Consultants plc, refers to early automotive engine developments and to the prevailing dilemma as to whether it was better — usually meaning less difficult or less costly — to seek increased performance by attending to the combustion system, or by reducing mechanical friction which dissipated a goodly portion of engine output long before it reached the road wheels.

Engine friction will continue to affect the efficiency of vehicle power plants as long as we have vehicles that use their own prime movers. A consequence of this, of course, is the fact that the truly “adiabatic” power plant needs rather more than an insulated combustion chamber. What is not so certain is the extent to which engine friction could be reduced and whether that reduction when achieved is worth all the effort.

This study investigates how disclosure of the board of directors’ leadership and role in risk oversight (BODs oversight disclosure) influences investors’ judgments when information on risk exposures is disclosed. The theoretical lens through which we examine this issue involves negativity bias. Sixty-two stock market investors who engage in the evaluation and/or investment of stocks on a regular or professional basis participated in our study. Our results reveal that the addition of BODs oversight disclosure (positive information) does not carry significant weight on investor judgments (i.e., attractiveness and investment) when financial statement disclosures indicate a high level of operational and financial risk exposures (negative information). In contrast, under the condition of a low level of risk exposures, BODs oversight disclosure causes investors to assess higher risk in terms of worry, catastrophic potentials and unfamiliarity about risk information and, in turn, make less favorable investor judgments. Our findings add to the literature on negativity bias and contribute to the debate on the usefulness of disclosures about risk.

This case offers the students to see the impact business ethics concepts, including corporate social responsibility, ethical obligation, ethical strategy, alienation, corporate activism, sociopolitical activism, symbolism, transparency, integrity, decoupled organization, opportunism, moral muteness or moral exclusion, etc. Through the student’s own ethical sensitivity, they can then make an informed decision grounded in fundamental ethical theories such as Utilitarianism, Kantianism, Ethics of Care, Virtue Theory, Confucianism, etc.

Data for this case has been gathered entirely from publicly available secondary sources, including online resources, mainstream media reports, biased (opinion-based) media outlets, social media statements from all stakeholder groups (students, business, university) and meeting minutes from campus organizations. None of the named individuals nor entities, in this case, have ever been contacted by the authors.

In Fall 2020, Boise State University contracted a locally owned and operated coffee shop to open a location on-campus. The shop owner was engaged to a police officer who had been permanently injured in an altercation with a dangerous fugitive. For his sacrifice, this police officer was awarded the Medal of Honor from the City of Boise. To support her fiancé, the coffee shop owner displayed a Thin Blue Line flag on the front door of her off-campus location. Students heard of this display and began to voice their objections through administrative and social media channels. The business countered back at claims that they supported racism and ultimately asked to be released from their contract with the university. They closed their on-campus business, having operated the location for less than two months. Media representation of this case created a vocal response both from those who support the business’ use of this imagery and those who support the student’s decision to boycott this business on ethical grounds.

Business ethics: 300–400 level; Business strategy: 300–400 level.

Experiencing academic difficulty can deter students’ academic momentum, decreasing the speed with which they complete coursework and increasing the odds that they will not persist to a credential. The purpose of this paper is to expand upon an existing framework that investigates students’ academic difficulty in co-enrolled courses by adding additional co-enrollment variables that may influence academic performance in introductory gateway courses.

This study uses quantile regression to better understand academic difficulty in co-enrolled courses and the impact that students’ co-enrollment patterns may have on their success in focal introductory gateway courses.

This study revealed significant relationships between student success and co-enrollment patterns, including: the disciplinary alignment of the course with a student’s major, the student’s co-enrollment in other difficult courses and experiencing below average academic performance in a co-enrolled course. Further, impact of these relationships often differed by students’ performance quantile in the focal course.

The results point to factors related to the student and their co-enrolled courses that faculty, academic advisors and curriculum committees can consider as they design general education requirements within and across disciplinary majors.

This approach advances the understanding of how a prescribed curriculum produces interdependent pathways that can promote or deter students’ success through the organization of curricular requirements and student course taking. The paper provides a generalizable methodology that can be used by other universities to investigate curricular pathways that have the potential to reduce student success.

The purpose of this paper is to examine the factors associated with franchisors going public using signaling theory. Listing on the stock market is a sign that the business concept has reached a threshold level of acceptance and success. To increase the relevance of this study to practitioners, the authors focus on franchising-specific controllable variables.

This study uses a sample of 2,134 franchisors from US drawn from a survey by Entrepreneur magazine during the years 2015–2016. Binominal logistic regression models are used for analysis of the data.

Findings indicate that time to franchise, international operations, franchise association affiliation, disclosure and extent of top management commitment are factors positively related to the likelihood of a franchisor being publicly listed.

Study findings are based on a sample of franchisors from North America, where financial markets are well developed, and due caution should be exercised before generalizations are made to other contexts. A major implication of this study is that signaling theory may provide an important supplement to the already well-entrenched resource-scarcity and agency theoretic explanations in franchising research.

While signaling theory is growing in importance in the franchising literature, this study is the first to uncover the relationship between company signals and initial public offering.

Biosolids, the residual solids from wastewater treatment operations and once considered a waste product by the industry, are now becoming increasingly recognised as a multifunctional resource with growing opportunities for marketable use. This shift in attitude towards biosolids management is spurred on by increasing volatility in energy, fertilizer and commodity markets as well as moves by the global community towards mitigating global warming and the effects of climate change. This chapter will provide an overview of current global biosolids practices (paired with a number of Australian examples) as well as discuss potential future uses of biosolids. Additionally, present and future risks and opportunities of biosolids use are highlighted, including potential policy implications.
