Investigating Information Systems Research in Canada

This project reports on the state of Information Systems (IS) research in Canada by analyzing research output and impact of Canadian IS scholars appearing in the form of peer‐reviewed journal articles. Specifically, we (a) measured individual productivity and impact, (b) measured institutional productivity and impact, (c) listed journals in which these works have appeared, (d) identified the most influential articles, (e) developed a ranking of IS scholarly journals from a Canadian perspective, and (f) compared the obtained journal ranking with the global IS journal rankings. Based on the findings, it was concluded that the Canadian IS discipline exhibits signs of academic maturity. Copyright © 2011 ASAC. Published by John Wiley & Sons, Ltd.     

What Types of Diversity Benefit Workers? Empirical Evidence on the Effects of Co‐worker Dissimilarity on the Performance of Employees

This study explores the consequences of grouping workers into diverse divisions on the performance of employees using a dataset containing the detailed personnel records of a large U.S. firm from 1989 to 1994. In particular, I examine the effects of demographic dissimilarity among co‐workers, namely differences in age, gender, and race among employees who work together within divisions, and non‐demographic dissimilarity, namely differences in education, work function, firm tenure, division tenure, performance, and wages among employees within divisions. I find evidence that age dissimilarity, dissimilarity in firm tenure, and performance dissimilarity are associated with lower worker performance, while wage differences are associated with higher worker performance. My analysis also reveals that the effects of certain types of dissimilarities get smaller in magnitude the longer a worker is a part of a division. Finally, the paper provides evidence that the relationships between performance and the various measures of dissimilarity vary by occupational area and division size.

Rural nonfarm employment and farming: household-level linkages

This article introduces the articles in Agricultural Economics , vol. 40 no. 2 (March 2009). First, we introduce their objectives in a brief review of existing literature on developing country trends in rural income diversification, in particular rural nonfarm employment (RNFE) and its impact on farm technology choice in crops and livestock, and thus on agricultural modernization and diversification. Then we preview the key points of the articles, which use distinctive primary datasets from Albania, Bulgaria, China, India, Mexico, Nigeria, the Philippines, Senegal, and Vietnam to document the impacts of RNFE and their implications for farm technology and farm activity.     

Taiwan aboriginal ecotourism: Tanayiku Natural Ecology Park

This paper discusses research into an ethno/ecotourism site developed by the Tsou nation of southern Taiwan. The Tanayiku Natural Ecology Park receives approximately 450,000 tourists annually. This paper assesses, from a poststructuralist perspective, the theoretical implications of what is termed an “ecocultural renaissance”. It shows that the park functions in two contradictory ways. First, it is a site of geopolitical resistance to colonization for the Tsou. Second, it is as a site of topological consumption—which is, effectively, continued colonization—by tourists. Paradox notwithstanding, the paper discusses why Tanayiku represents a rare example of a successful community-based ecotourism operation owned and operated exclusively by an aboriginal group.     

How Positive and Neo‐Aristotelian Leadership Can Contribute to Ethical Leadership

Virtuous leadership is crucial for advancing leadership ethics. By comparing Positive Leadership and its notion of virtuousness with neo‐Aristotelian leadership based on virtue, this article sheds light on this research field. We expound on the differences and commonalities between the two and present possibilities of how they can enrich each other and further ethical leadership theory. Our findings concern the purported Aristotelian roots of virtuousness, the relative strengths and weaknesses of the positive and the neo‐Aristotelian approaches, and the interplay between technical skills and ethical excellence in leadership. We propose the adoption of practical managerial tools and procedures from Positive Leadership, making them dependent upon the virtues to achieve flourishing within organizations and society at large. © 2018 ASAC.

MULTIFRACTIONAL STOCHASTIC VOLATILITY MODELS

The aim of this work is to advocate the use of multifractional Brownian motion (mBm) as a relevant model in financial mathematics. mBm is an extension of fractional Brownian motion where the Hurst parameter is allowed to vary in time. This enables the possibility to accommodate for varying local regularity, and to decouple it from long‐range dependence properties. While we believe that mBm is potentially useful in a variety of applications in finance, we focus here on a multifractional stochastic volatility Hull & White model that is an extension of the model studied in Comte and Renault. Using the stochastic calculus with respect to mBm developed in Lebovits and Lévy Véhel, we solve the corresponding stochastic differential equations. Since the solutions are of course not explicit, we take advantage of recently developed numerical techniques, namely functional quantization‐based cubature methods, to get accurate approximations. This allows us to test the behavior of our model (as well as the one in Comte and Renault) with respect to its parameters, and in particular its ability to explain some features of the implied volatility surface. An advantage of our model is that it is able both to fit smiles at different maturities, and to take volatility persistence into account in a more precise way than Comte and Renault.     

The Effect of SNAP and School Food Programs on Food Security,Diet Quality,and Food Spending: Sensitivity to Program Reporting Error

There is an extensive research literature on the effects of the Supplemental Nutrition Assistance Program (SNAP) on food‐related outcomes which has shown somewhat mixed results but generally favorable effects. However, most of the research has used data sets whose information on SNAP participation is gathered from responses on household surveys, and such responses are subject to reporting error. This study uses the National Household Food Acquisition and Purchase Survey data set to examine the effect of reporting error on food‐related outcomes, for that data set contains information on SNAP participation gathered from government administrative records. Our analysis shows that the degree of reporting error is small and has little effect on the estimated impact of participation in the SNAP program on food security, diet quality, and food spending. A supplemental analysis of the effect of school food programs likewise shows no difference in using survey or administrative data in the analysis.     

The Relevance of XBRL Voluntary Disclosure for Stock Market Valuation: The Role of Corporate Governance

The aim of this paper is to investigate the relevance for stock market pricing of accounting earnings of voluntary disclosures in XBRL files considering the quality of corporate governance. Results are the following. It appears that XBRL extensions attract financial analysts. Good governance is positively associated with voluntary XBRL extensions. We observe that XBRL extensions enhance the positive relationship between accounting earnings and stock price. However, this positive association is reduced for firms with good governance, suggesting a substitution effect between XBRL extensions and corporate governance. Finally, it appears that XBRL extensions would strategically be related to earnings quality. This research highlights the importance to consider governance when assessing the value relevance of XBRL disclosures for stock market pricing.     

A Career Path Leading to Well‐being and Success

In line with self‐determination theory (Deci & Ryan, 2000), this study aims to determine the influence of different contents and motives of career aspirations, together with objective career success, on subjective career success and well‐being. Moreover, it aims to verify if psychological need, satisfaction, and frustration play a mediating role in these relationships. Results suggest that the pursuit of some aspirations and the underlying motives for their pursuit are more beneficial. Aspiration contents, and aspiration motives, together with objective career success, influence subjective well‐being and subjective career success, in part because they satisfy or frustrate psychological needs. This study brings together two fields of research evolving in parallel—career and life aspirations— to shed new light on both of them. Copyright © 2018 ASAC. Published by John Wiley & Sons, Ltd.
