UNLABELLED Online knowledge resources such as Medline can address most clinicians' patient care information needs. Yet, significant barriers, notably lack of time, limit the use of these sources at the point of care. The most common information needs raised by clinicians are treatment-related. Comparative effectiveness studies allow clinicians to consider multiple treatment alternatives for a p...

Mixed logit is a highly flexible model that can approximate any random utility model. In this paper, two kinds of mixed multinomial logit models were considered. The main aim was to introduce a locally D-optimal criterion to obtain an optimal combination of the levels of attributes for producing alternatives and an optimal combination of alternatives in choice sets. Thus, a design including cho...

Fourteen out of 150 (9.3%) consecutive strains of Haemophilus influenzae isolated on culture of sputum in the Bacteriology Department, Belfast City Hospital, during 1982/83 were found to be ampicillin-resistant (beta-lactamase-producing). Susceptibility testing to other antibiotics of these ampicillin-resistant strains showed that cefuroxime, cefotaxime, gentamicin, and amoxycillin with clavula...

Mental disorders and criminal behavior are considered to fall under the rubric of deviance. This perspective of deviant behavior forms the framework for comparing community-based programs for emotionally disturbed persons and for offenders with institutionally based program~ The interactionist model lends itself to the development of community-based modalities in lieu of institutionalization; i...

The theoretical performance of some flammable refrigerants, namely, propane (HC290), butane (HC600), isobutane (HC600a), cyclopropane (HCC270), HFC152a and HCFC142b have been comparativelyassessed as alternatives to CFC12. Th~s has been done for a range of evaporating temperatures by using some standard refrigera~ion parameters like pressure ratio, ·specific compressor displacement, theoretical...

This paper criticizes the use of multiple regression (MR) in the fields of comparative social policy and political economy and proposes alternative methods of numerical analysis. The limitations of MR in its characteristic guise as a means of hypothesis-testing are well known. The emphasis here is on the specific difficulties of applying MR to the problem of explaining diverse outcomes across a...

A third generation of environmental policy making and risk management will increasingly impose environmental measures, which may give rise to analyzing countervailing risks. Therefore, a comprehensive analysis of all risks associated with the decision alternatives will aid decision-makers in prioritizing alternatives that effectively reduce both target and countervailing risks. Starting with th...

BACKGROUND The substitution principle has been included in the EU pesticides legislation as a new element. Comparative assessments will have to be conducted for all uses of plant protection products (PPPs) that contain active substances with certain hazardous properties, the so-called candidates for substitution (CFS). This study investigated the resulting workload in terms of the number of cas...
