Abstract

Purpose

The purpose of this paper is to provide academic researchers and practitioners with a better understanding of the current Ivey Purchasing Managers Index (IPMI), with alternative IPMIs, and with their appropriateness as an indicator of the performance of the Canadian economy.

Design/methodology/approach

The paper makes use of principal component analysis to investigate the choice of principal variables for computing new IPMIs based on monthly data for five Ivey indexes for the period from December 2000 to May 2006. Statistical tests were made for the validity of the existing and new IPMIs using two major indicators of Canadian business and economic activities.

Findings

The results suggest that a new composite purchasing managers index for Canada similar to its US counterparts be computed based on four identified Ivey indexes. For constructing a simpler and parsimonious IPMI, the results support Ivey's current practice of using only one Ivey index, namely, the Purchases index.

Research limitations/implications

There was a limited amount of data used for the analysis (i.e. monthly data for less than six years). Also there are issues on data comparability between the Ivey data and the US data (i.e. the Ivey does not collect separate data for the manufacturing sector or the non‐manufacturing sector).

Practical implications

Using a composite index akin to the PMI, business organizations and policymakers will have an accurate sense of what is happening in the Canadian economy. Furthermore, enhancing the power and accuracy of such an index will benefit supply professionals, economic forecasters, and policy experts.

Originality/value

The present study offers additional insights to both practitioners and academics. It helps supply chain managers and practitioners come up with a more reliable business strategy by providing them with a weighted composite index for the Canadian economy. It also makes contributions to the academic community in the area of statistical theory applied to supply management as it has introduced the principal components variable selection analysis in the construction of a new IPMI.

Abstract

Purpose

The purpose of this paper is to investigate structural changes in the elasticity of demand for wine in the Province of Ontario and in Canada as a whole. It will provide academic researchers and practitioners with a better understanding about structural changes in the levels of wine demand elasticities over time. It will also help the relevant governments and wine business establishments in developing taxation policy and business decisions.

Design/methodology/approach

The Kalman filter method, in conjunction with the Chow test, is applied to investigate structural changes in the elasticity of demand for wine. The Chow test is used for primary investigations of structural changes in the elasticity of demand for wine over time, whereas the Kalman filter method provides information about the behavior of the elasticity coefficients over time.

Findings

The Chow test reveals that structural changes in wine demand for Ontario are more pronounced than those for Canada as a whole. The Kalman filter results indicate that increased (decreased) government taxation could be an effective tool for discouraging (encouraging) consumption of wine. The analysis of own‐price elasticity suggests that the effects of increased government taxation on wine consumption be totally unexpected. Cross‐price elasticity coefficients change their signs over time, suggesting that some of the goods that are considered to be complements may become substitutes. Income and unemployment levels have different effects on wine consumption in Ontario and in Canada as a whole.

Research limitations/implications

There may be variation in results by wine color (red or white), country of origin (imported or domestic), or price (premium or non‐premium).

Practical implications

Understanding changes in the elasticity of demand structure for wine over time would help policy makers at the provincial and federal levels come up with effective tools for controlling consumption of wine over time, including their taxation policies. For the wine business establishments, the information on consumer response is important for pricing purposes.

Originality/value

The Kalman filter has not previously been used to examine structural changes in the demand for wine in Canada.

Abstract

Purpose

The paper seeks to provide academic researchers and practitioners with a better understanding about purchasing strategies through an integrated approach to supplier selection and purchasing decisions.

Design/methodology/approach

This paper views supplier selection as a multi‐criteria problem. Through the analytical hierarchy process (AHP), in consideration of both quantitative and qualitative criteria, a set of candidate suppliers is identified. A multi‐objective linear programming (MOLP) model, with multiple objectives and a set of system constraints, is then formulated and solved to allocate the optimum order quantities to the candidate suppliers.

Findings

The paper provides tradeoffs among different objectives, which are more consistent with the complexity and nature of the real‐world decision‐making environment. It also offers better information and solutions supporting effective purchasing decisions.

Research limitations/implications

The main concept of the proposed approach can be applicable to any organization with a purchasing function. However, its implementation will be very specific to a particular organization of interest, as each individual organization must define its own subjective criteria and constraints. The area of decision support system development, which automates (or computerizes) the input process of the proposed models and integrates with other databases in a company, will provide great opportunities for future research.

Practical implications

The paper provides practitioners with flexibility and effectiveness in their supplier selection and purchasing decision process and with a better understanding about their future purchasing strategies. The results from the application of the proposed models to the supplier selection problem at a high‐technology firm in Taiwan show that the models are effective and applicable.

Originality/value

This paper takes an integrated approach to problem analysis (i.e. multi‐objectives with both quantitative and qualitative information), uses a sound scientific methodology in model development (i.e. integrating AHP with MOLP), and provides practical use of the models. It offers additional knowledge and value to both academics and practitioners.

Abstract

This chapter complements the one that appeared as “History of the AIB Fellows: 1975–2008” in Volume 14 of this series (International Business Scholarship: AIB Fellows on the First 50 Years and Beyond, Jean J. Boddewyn, Editor). It traces what happened under the deanship of Alan Rugman (2011–2014) who took many initiatives reported here while his death in July 2014 generated trenchant, funny, and loving comments from more than half of the AIB Fellows. The lives and contributions of many other major international business scholars who passed away from 2008 to 2014 are also evoked here: Endel Kolde, Lee Nehrt, Howard Perlmutter, Stefan Robock, John Ryans, Vern Terpstra, and Daniel Van Den Bulcke.

Abstract

Growing interest in the use of digital technologies and a Putnam-inspired debate about youth engagement has drawn researchers from outside of the study of social movements into research on the topic. This interest in youth protest participation has, in turn, developed into a substantial area of research of its own. While offering important research contributions, we argue that these areas of scholarship are often not well grounded in classic social movement theory and research, instead focusing on new media and/or the relationship between activism and other forms of youth engagement. This chapter seeks to correct this by drawing on interviews with 40 high school and college students from a moderately sized southwestern city to examine whether traditional paths to youth activism (i.e., family, friends, and institutions) have changed or eroded as online technology use and extra-institutional engagement among youth has risen. We find that youth continue to be mobilized by supportive family, friends, and institutional opportunities, and that the students who were least engaged are missing these vital support networks. Thus, it is not so much that the process driving youth activism has changed, but that some youth are not receiving support that has been traditionally necessary to spur activism. This offers an important reminder for scholars studying youth and digital activism and youth participation more broadly that existing theory and research about traditional pathways to activism needs to be evaluated in contemporary research.

Abstract

Purpose

In some fields, research group experiences gained in laboratories are more influential than the classroom in shaping graduate students’ research abilities, understandings of post-graduate careers and professional identities. However, little is known about what and how students learn from their research group experiences. This paper aims to explore the learning experiences of engineering graduate students in one chemical engineering research group to determine what students learned and to identify the practices and activities that facilitated their learning.

Design/methodology/approach

Ethnography was used to observe the experiences of one research group in chemical engineering. Fieldwork included 13 months of observations, 31 formal interviews (16 first-round and 15 second-round interviews) and informal interviews. Fieldnotes and transcriptions were analyzed using grounded theory techniques.

Findings

Research group members developed four dominant competencies: presenting research, receiving and responding to feedback, solving problems and troubleshooting problems. Students’ learning was facilitated by the practices and activities of the research group (e.g. weekly full group and subgroup meetings) and mediated through the interactions of others (i.e. peers, faculty supervisor and lab manager).

Originality/value

This study adds to the engineering education literature and contributes to the larger discourse on identifying promising practices and activities that improve student learning in graduate education.

Abstract

Most years, several AIB members are elected as AIB Fellows on account of their excellent international business scholarship, and/or past service as AIB President or Executive Secretary. The Fellows are in charge of electing Eminent Scholars as well as the International Executive and International Educator (formerly, Dean) of the Year, who often provide the focus for Plenary Sessions at AIB Conferences. Their history since 1975 covers over half of the span of the AIB and reflects many issues that dominated that period in terms of research themes, progresses and problems, the internationalization of business education and the role of international business in society and around the globe. Like other organizations, the Fellows Group had their ups and downs, successes and failures – and some fun too!

Abstract

Purpose – With an acknowledgement to Benedict Anderson's seminal writings on “imagined communities,” this paper examines several meanings and uses of the concept of imagination: theoretical, methodological, and substantive.

Methodology/approach – Application of these meanings are illustrated from eight qualitative researches, combining direct observations, interviews, participant observation, and document analysis.

Findings – Data are drawn from diverse settings, such as undocumented migrant communities, terrorism, Native American communities, collaborative divorce, nationalism, mass killers, players of video games, and genocide, to illustrate the potential uses and meanings of imagination.

Originality – These diverse researches illustrate the potential empirical and research contributions of these ideas.
