In 1994 the Laboratory Centre for Disease Control (LCDC), Health Canada, commissioned one of us (R.S.R.) and a co-investigator to characterize the epidemiology of transfusion-associated HIV infection in Canada before serologic testing was implemented. In this study, presented in part to the Commission of Inquiry on the Blood System in Canada (the Krever Commission), we estimated through statist...
This case study describes how sociocultural and activity theory were applied in the design of a publicly funded, Canadian Language Benchmark (CLB)-based English as a Second Language (ESL) credential program and curriculum for immigrant and international students in postsecondary institutions in British Columbia, Canada. The ESL Pathways Project was conceived to prepare immigrant students to nav...
Learner’s dictionaries are at the forefront of lexicographical practice; it is through them that corpora have become standard practice, through them that the most dynamic electronic dictionaries have come onto the market. The market for such dictionaries is enormous with the big five working hard to keep and increase their share of the market. However, it may well be that they are failing to ta...
BACKGROUND Elderly patients with metastatic melanoma have different disease characteristics and a poorer prognosis than younger patients. Data from clinical trials and expanded access programmes (EAPs) suggest ipilimumab confers a consistent survival benefit and has a similar safety profile across different age groups of patients with metastatic melanoma. Here we report the efficacy and safety ...
This paper presents a new concept design for satellite attitude control. This new concept is based on the use of electroactive polymer beams which control the rotations of a satellite taking advantage of the angular momentum conservation of the whole system. By employing electroactive polymers, a compact and lightweight pointing system is obtained which allows to reduce the need of noisy spinni...
INTRODUCTION Envenomation by scorpion stings is a major public health problem in numerous tropical countries because of its frequent incidence and potential severity. Approximately 1,900 species of scorpions are known in the world, and at least 130 of these have been described in Brazil. METHODS This work reports on 3 child deaths caused by Tityus stigmurus stings and characterizes epidemiolo...
This specification defines a new EAP method, EAP-AKA’, a small revision of the EAP-AKA method. The change is a new key derivation function that binds the keys derived within the method to the name of the access network. The new key derivation mechanism has been defined in the 3rd Generation Partnership Project (3GPP). This specification allows its use in EAP in an interoperable manner. In addit...
IKEv2 is a protocol for exchanging keys in the IPsec architecture. In it's specification, EAP was proposed as one of the authentication mechanisms. EAP is extensible authentication protocol based on client/server architecture and allows introduction of additional EAP methods. Implementation of this protocol is complex and in our project it was decided to include one of the existing implementati...
ABSTRACT A good clustering algorithm should not only be able to discover clusters of arbitrary shapes (global view) but also provide additional information, which can be used to gain more meaningful insights into the internal structure of the clusters (local view). In this work we use the mathematical framework of factor graphs and message passing algorithms to optimize a pairwise similarity ba...
BACKGROUND Health care providers do not routinely carry out brief counseling for tobacco cessation despite the evidence for its effectiveness. For this intervention to be routinely used, it must be brief, be convenient, require little investment of resources, require little specialized training, and be perceived as efficacious by providers. Technological advances hold much potential for address...
