    The Attitude of Canadian Nurses Towards Advance Directives
    with D. Blondeau, M. Lavoie, P. Valois, E. W. Keyserlingk, and I. Martineau
    Nursing Ethics 7 (5): 399-411. 2000.
    This article seeks to shed light on the beliefs that influence nurses’ intention of respecting or not respecting an advance directive document, namely a living will or a durable power of attorney. Nurses’ beliefs were measured using a 44-statement questionnaire. The sample was made up of 306 nurses working either in a long-term care centre or in a hospital centre offering general and specialized care in the province of Québec. The results indicate that nurses have a strong intention of complying…Read more

    Comparison of patients' and health care professionals' attitudes towards advance directives
    with D. Blondeau, P. Valois, E. W. Keyserlingk, and M. Lavoie
    Journal of Medical Ethics 24 (5): 328-335. 1998.
    OBJECTIVES: This study was designed to identify and compare the attitudes of patients and health care professionals towards advance directives. Advance directives promote recognition of the patient's autonomy, letting the individual exercise a certain measure of control over life-sustaining care and treatment in the eventuality of becoming incompetent. DESIGN: Attitudes to advance directives were evaluated using a 44-item self-reported questionnaire. It yields an overall score as well as five fa…Read more

    We give syntactic characterizations of1. the theories whose categories of models are closed under the formation of pullbacks, and of2. the locally ω-polypresentable categories.A somewhat typical example is the category of algebraically closed fields. Case is proved by classical model-theoretic methods; it solves a problem raised by H. Volger . The solution of case is in the spirit of the ones for the locally ω-presentable and ω-multipresentable cases found by M. Coste and P.T. Johnstone respecti…Read more

    Syntactic characterization of closure under connected limits
    Archive for Mathematical Logic 31 (2): 133-143. 1991.
    We give a syntactic characterization of (finitary) theories whose categories of models are closed under the formation of connected limits (respectively the formation of pullbacks and substructures) in the category of all structures. They are also those theories whose consistent extensions by new atomic facts admit in each component an initial structure (respectively an initial term structure), and also thoseT for whichM(T) is locally finitely multi-presentable in a canonical way. We also show th…Read more
