Large input currents can be generated by an asymmetry in the chloride activity seen by Ag-AgCl electrodes used at the input of intracellular amplifiers because offset compensation no longer takes place at the input of the amplifier but rather later in the circuit in many modern amplifiers. This situation occurs when chloride-free solution, such as potassium… (More)
In the cone pedicules, the digitations of horizontal cell process lateral to the synaptic ribbon disappear after dark adaptation. This disappearance is correlated with the loss of color opponency and cone function shown in ganglion cell recordings in isolated retinas. Cone function and color-opponent responses are restored by reapplying background light.
Driven by requests from Internet-savvy students, a large number of universities and educational institutions have started to design, develop and use information and communication technology to create, share and disseminate instructional material. Commercial tools, such as Blackboard and WebCT, are available to offer basic course management functionalities.… (More)
UNLABELLED We determined if nurses can manage osteoporotic fractures in a fracture liaison service by asking a rheumatologist and an internist to assess their clinical decisions. Experts agreed on more than 94 % of all nurses' actions for 525 fragility fracture patients, showing that their management is efficient and safe. INTRODUCTION A major care gap… (More)
A syllabus forms the structure of a course (or program) offering and is used to assemble its constituents. Course websites and LMS's, also contain similar information, and in some sense, are quite similar to course outlines or syllabi, and replicate some of the information that can also be found in administrative websites of universities. From a system… (More)
Still at the center of university teaching, syllabi, either in paper or electronic format (PDF, HTML), are not easily accessible to students or the general public. Moreover, the users interfaces and the vocabulary employed can vary across courses, an unnecessary hurdle for the users. HEC Montreal has sucessfully launched Course Zone… (More)
Recent work on policy rules under uncertainty have highlighted the impact of output gap measurement errors on economic outcomes and their importance in the formulation of appropriate policy rules. This paper investigates the reliability of current estimates of the output gap in Canada. We begin by assembling a new data base of quarterly real-time output… (More)
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… (More)
