The role, effectiveness, and even existence of hospital ethics committees (HECs) are not universally agreed upon. Over the past 20 years, the study of HECs has focused mainly on their structure, scope, and function, making the results more descriptive than anything. In an effort to present study results that could help HECs better serve the needs of their organizations, the authors of this arti...

This paper presents a modeling application of surface runoff using the Hydrologic Modelling System (HEC-HMS). A case study was carried out for the Jianghe watershed, a typical semi-arid and sub-humid geo-climatic region in northern China. Two modeling schemes using different descriptive sub-mechanism models provided by HEC-HMS for runoff volume, direct runoff and routing (channel flow) were inv...

As indicated by Becker and Watts (2001), teaching in economics and finance is still mostly done in a Chalk and Talk passive learning environment. This paper reports on an active, hands-on approach implemented for business students enrolled in an undergraduate course in options and futures at HEC Montréal. The proposed environment adapts and extends the studio approach first developed for Introd...

The complexity of modern scientific software is an important issue that needs to be addressed as part of an effort to revitalize high end computing (HEC). The complexity arises from both the scientific demands and the increasingly complex computers on which the software is run. We believe that HEC software developers need to be able to use a higher level of abstraction to express their computat...
