Income Tax Accounting Policy Choice: Exposure Draft Responses and the Early Adoption Decision by Canadian Companies*

We extend prior literature through a detailed examination of the relationship between lobbying behavior and subsequent accounting standard adoption timing, using changes to a Canadian accounting standard with a prolonged transition period. We develop a model linking lobbying and adoption timing. We test hypotheses based on recontracting costs, information production costs, efforts to manage investor perceptions, and corporate governance practices to assess the ability of these factors to explain corporations' choice of adoption timing. We examine responses to the Income Taxes exposure draft using content analysis to identify trends in lobbying behavior. We evaluate the accounting standard adoption decision for Toronto Stock Exchange (TSE) 300 firms using a LOGIT model. Our findings indicate that early adoption appears to be most prevalent for firms that benefit from improved financial statement performance. In contrast, late adopters tend to be firms that have lobbied standard‐setters regarding the out‐of‐pocket costs of the standard and that rate highly on certain corporate governance measures.     

A learning methodology using Matlab/Simulink for undergraduate electrical engineering courses attending to learner satisfaction outcomes

Learner-centred approaches follow the prevailing tendency in modern University reforms which are primarily concerned about “how people learn”. The methodologies can be learner-centred in the sense of placing the student as the main actor of the teaching–learning process by increasing his interactivity and participation, but also considering what is relevant for the student by measuring the learner satisfaction. In order to promote both aspects, this paper proposes a synchronous software-based active methodology that makes use of the simulations to show a virtual scenario to the students and challenge them to predict and discuss the evolution of the scenario. The proposed methodology improves the visual interface, promotes discussion both among students and with the teacher in a brainstorming stage and shows real-world examples. This software-based methodology has been implemented into an Electric Machinery course at the University of Seville (Spain), and the evaluation has been carried out considering both the affective and cognitive domains. Principal components analysis proves to be useful to highlight the dimensions with a higher influence on learner satisfaction and the affective and cognitive results confirm the successful implementation of the proposal.     

Commercial exploitation of new technologies arising from university research: start-ups and markets for technology

The creation of start-up firms is an important method of commercializing new technologies arising from R&D at universities and other research institutions. Most research into start-ups presumes that these firms develop products or services. However, start-ups may operate through markets for technology by selling or licensing rights to use their technology to other firms – typically established firms – who develop and sell new products or services based on the technology. In this study of 57 public start-up firms created to commercialize the results of university research, we find evidence that (1) operating through markets for technology is a common approach to commercialization, (2) start-ups that operate in markets for technology can be effectively distinguished in practice from start-ups operating through product markets, and (3) there are substantive differences in the business activities of firms depending on whether they operate through product markets or markets for technology.     

Sales channel integration after mergers and acquisitions: A methodological approach for avoiding common pitfalls

This article addresses the integration of sales channels after mergers and acquisitions (M&A) by appraising the strengths, weaknesses, and biases associated with the four most common frameworks for evaluating sales channels (sales management, historical performance, strategic fit, and customer choice) for their appropriateness in a post-M&A context. The authors develop a methodological approach that uses a balanced-scorecard framework to guide managers through the sales channel integration process, and then apply this approach to the merger of two industrial firms' sales organizations across 21 territories. In so doing, they reveal various pitfalls and propose and test some analytical corrections. Longitudinal performance data support comparisons across the different evaluative frameworks; in particular, the sales management and customer choice frameworks provide the most insight into channel partners' post-integration performance. The results support the premise that channel integration can be improved by accounting for factors unique to the M&A context and using an approach that triangulates multiple perspectives.     

Closing speech

M. Pilliard explained that he was not speaking as an academic, a researcher, a sociologist or a futurologist, but as an industrialist From this starting point he was concerned with broadening the idea of product and extending the role of demand in the search for innovation. He was also concerned with the way in which the different stages of R & D evolution related to the growing interdependence of business with its environment
