The objective of this study was to describe how the Childhood Autism Rating Scale (CARS) behaves in relation to the Autism Diagnostic Observation Schedule (ADOS) and to clinical diagnosis based on the criteria defined in the Diagnostic and Statistical Manual of Mental Disorders, 4 th Edition (DSM-IV) for children of immigrant parents. Forty-nine children of parents who had immigrated to Canada ...

In designing a quality report, a health plan needs to account for the report's effect on the doctor, hospital or other provider. This paper proposes a simple model of how quality reporting affects a health care provider, using the example of a doctor subject to reporting with a "cut point" that designates the doctor as above or below some standard. Choice of cut point affects the doctor's welfa...

OBJECTIVE To determine which cut-off point in the RA disease activity score (DAS28) corresponds to fulfilment of the ARA criteria for clinical remission. METHODS The disease activity of patients included in the Nijmegen RA inception cohort was systematically assessed every 3 months. For all visits, a modification of the ARA preliminary criteria for clinical remission was applied and the DAS28...

OBJECTIVE To estimate the prevalence of cognitive impairment in an elderly population-based cohort, using several Mini-Mental State Examination (MMSE) cut-off points recommended by Brazilian authors and to examine the percentile distribution of MMSE scores in the study population. METHOD A total of 1558 subjects aged>60 years (89.4% of the total), living in the city of Bambuí, MG, completed t...

How can we find the deepest disjunctive cut in some direction by using lift-and-project? We introduce the Reverse Polar Cut Generating Linear Program (RP-CGLP), which evaluates disjunctive cuts according to their slack for a point p in the disjunctive hull when having the same violation with respect to the fractional solution x' being separated. We show that the resulting cut defines a supporti...

The ROC (Receiver Operating Characteristics) curves are frequently used to measure the effectiveness of diagnostic biomarkers. A global measure of the ROC curve is the Youden index, the maximum difference between sensitivity and 1-specificity. The cut-point is the value for which the maximum is attained. In this paper we obtain the asymptotic distribution of the optimal cut-point under the assu...

We reflect upon an analogue of the cut locus, a notion classically studied in Differential Geometry, for finite graphs. The cut locus C(x) of a vertex x shall be the graph induced by the set of all vertices y with the property that no shortest path between x and z, z 6= y, contains y. The cut locus coincides with the graph induced by the vertices realizing the local maxima of the distance funct...

INTERACTIVE PART SELECTION FOR MESH AND POINT MODELS USING HIERARCHICAL GRAPH-CUT PARTITIONING Steven W. Brown Department of Computer Science Master of Science This thesis presents a method for interactive part selection for mesh and point set surface models that combines scribble-based selection methods with hierarchically accelerated graph-cut segmentation. Using graph-cut segmentation to det...
