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.     

The influence of information communications technology (ICT) on cash management and financial department performance: An explanatory model

We delineated the extent to which various facets of information communications technology (ICT) are used and are perceived as useful by treasury managers, focusing on three indicators of financial department performance: cost savings, improvements in the quality of the information, and enhancements in the use of scenario simulations for decision making. Specifically, we examined the relationship between ICT use in cash management functions within financial departments, perceptions of the importance of cash management to treasury managers, and their perceptions of the usefulness of ICT to financial department performance. The theoretical and applied implications of these findings are discussed. Copyright © 2009 ASAC. Published by John Wiley & Sons, Ltd.     

Workplace risks and stressors as predictors of burnout: The moderating impact of job control and team efficacy

Air medical healthcare (AMH) professionals care for critically-ill individuals while conveying them to healthcare centres from distant, and frequently dangerous, locations. AMH professionals experience additional health and safety issues beyond the “typical” stressors faced by other healthcare professionals. Therefore, we integrated the safety and psychosocial health literatures to examine the relationship between workplace stressors (risk perception, worries, and patient-care barriers) and two components of burnout (emotional exhaustion; depersonalization), and the moderating impact of job control and team efficacy for 106 Canadian AMH professionals. Worries over medical hassles and barriers to patient care uniquely predicted emotional exhaustion. Lack of perceived control over one's job was related to exhaustion and depersonalization after controlling for stressors. Job control and team efficacy buffered some of the stressor-burnout relationships. Copyright © 2009 ASAC. Published by John Wiley & Sons, Ltd.     

The Development of a Process for Evaluating Marketing Sponsorships

Despite the increasing resources being allocated from marketing budgets to sponsorship, effective evaluation is relatively rare, and sponsorship evaluation methods are often proprietary in nature. This paper reports on a research project designed to develop a process model for evaluating sponsorships. An initial version was conceived from agency theory, the evaluation literature, and sponsorship writings. This draft was then assessed by sponsorship experts during a series of 14 in‐depth interviews. Based on these analyses, a final version of the process model was proposed. The revised version was then adopted to evaluate—as a demonstrative example—a specific sponsorship. Results of this case and recommendations for future research and practice in sponsorship evaluation are presented. Copyright © 2011 ASAC. Published by John Wiley & Sons, Ltd.     

Stock recommendations and investment portfolio formation: A study in the Brazilian market

The stock analysts have a relevant role in the capital market, since, directly or indirectly, they contribute to the paper pricing and to the composition of the investment portfolio. The purpose of this study is to verify if it is possible to obtain extraordinary returns, above those offered by a market portfolio, with the monitoring of the stock recommendations issued by Brazilian capital market analysts, one of the most important in Latin America. Based on a wide range of consensual recommendations concerning the period from 2000 to 2010, and with the monitoring of the historical series of paper returns covered by the analyses, the performance of two portfolios were compared, one formed by stocks that received favorable and the other one formed by stocks that received unfavorable analyst recommendations. The results showed bias in recommendations, since there is, systematically, a greater number of favorable against unfavorable recommendations. The results mainly showed that the analysts were unable to identify the stocks that actually offered greater returns within the period considered.     

外来词义的移植：现代汉语非派生式新义探源——兼谈《现代汉语词典》在词的比喻义收释中存在的不足

一些外来词义之所以能顺利“移植”现代汉语词义系统中,主要原因在于：（1）汉外对应词词义的不完全对应导致了汉语词义空位的产生;（2）汉外对应词中外语词新义的产生也会导致汉语词词义空位的形成;（3）外来词语直译所带来的汉语固有词或语素（以单音节为主）意义的变化也会形成汉语固有词或语素的意义空位。这也给《现代汉语词典》等语文辞书释义的充实和完善带来了新的挑战。     

Valuing Mangrove-Fishery Linkages – A Case Study of Campeche, Mexico

This paper explores the value of mangrove systems as a breeding and nursery habitat for off-shore fisheries, focusing on mangrove-shrimp production linkages in Campeche State, Mexico. We develop an open access fishery model to account explicitly for the effect of mangrove area on carrying capacity and thus production. From the long-run equilibrium conditions of the model we are able to establish the key parameters determining the comparative static effects of a change in mangrove area on this equilibrium. We then estimate empirically the effects of changes in mangrove area in the Laguna de Terminos on the production and value of shrimp harvests in Campeche over 1980–90. Our findings suggest that mangroves are an important and essential input into the Campeche shrimp fishery, but that the low levels of deforestation between 1980 and 1990 mean that the resulting losses to the shrimp fishery are still comparatively small. Over-exploitation of the fishery due to open access conditions remains the more pervasive threat, and without better management any long-run benefits of protecting mangrove habitat are likely to be dissipated.

Análisis del desnivel salarial entre hombres y mujeres con un modelo de equilibrio

Según un modelo de equilibrio generalde dos esferas (hogary mercado), la productividad de la mujer en el trabajo remunerado disminuye cuantas más tareas desempeña en el hogar. Partiendo del supuesto de que las aportaciones de hombres y mujeres a las labores domésticas son complementarias, las autoras comprueban que hay múltiples equilibrios posibles. En algunos, ellosy ellas asumen estas tareas por igualy ganan salarios iguales; en otros, se las reparten de manera dispar y ganan salarios diferentes. Por otraparte, los estereotipos acerca de la productividad de las mujeres perpetúan la desigualdad. Las autoras, valiéndose de ejemplos numéricos, demuestran que hay mayor bienestar cuando los cónyuges se reparten el trabajo a partes iguales. Para terminar, exponen algunas conclusiones.     

Tourism and crime in the Caribbean

This study reviews the general literature on tourism and crime and the recent history of violent and property crime in several Caribbean destinations. It highlights the failure of most previous research to discriminate crimes against tourists vs. residents. Annual crime data for Barbados for 1989–93 are analyzed and reveal that overall guest victimization rates are higher than host rates. Residents are significantly more likely to be victimized by violent crime while tourists are significantly more likely to experience property crime and robbery. Monthly data on guest victimization for 1990–93 show similar patterns. The paper concludes with a number of measures to enhance tourist safety.
