Participative decision making (PDM) at South African universities
… perceptions about participative decision making (PDM). The outcome was that managers hold negative perceptions about participative decision making. This leads to the conclusion that university managers do not practice participative decision making (PDM). The difference between those who hold …

Optimization of Fast MR Imaging Technologies using the Case-PDM to Quantitatively Assess Image Quality
… We developed a perceptual difference model, Case-PDM, to quantitatively assess image quality, in a way well-correlated to clinical needs, and demonstrate how the methods can be used to improve MR imaging techniques. We validated existing Case-PDM with advanced observer experiments. Human …

Phase derivative microscopy of biological cells and tissues
Phase derivative microscopy (PDM), including Laplace field microscopy (LFM) and gradient field microscopy (GFM), generates high contrast images of transparent specimens. These methods utilize spatial light modulation at the Fourier plane of a bright field microscope to optically obtain the …

Analysis of Dietary Intake, Body Composition and Biomarkers in Adults with Type 2 Diabetes Mellitus, Prediabetes and Without Diabetes
… type 2 diabetes mellitus (T2DM) and prediabetes (PDM) to adults without diabetes. A total of 22 participants (PDM/T2DM n=12, controls n=10) in the San Luis Obispo, CA area completed the study prior to our ending recruitment due to Covid-19. Body composition data were collected through DXA scans. …

Is What They Get What They Really Need? Critical Analysis of Professional Development Models Used With Elementary Science Teachers in One School District in South Africa
… model with the elementary science teachers. This PDM did not address various challenges and complexities within the school district and therefore created a number of challenges that negatively impacted the success of the new curriculum reforms in the district. (b) Teachers believed that they were …

Participative Decision-Making in the Schools: A Multidimensional Model
… the relationships between the dimensions of PDM and work-related attitudes and relationships (e.g., interpersonal trust at work, organizational commitment). Results were, for the most part, in the predicted direction and consistent with the proposed model. Some PDM forms appeared to be more …

Perceptual data mining : bootstrapping visual intelligence from tracking behavior
… This thesis is about Perceptual Data Mining (PDM), the primary goal of which is to create a real-time, autonomous perception system that can be introduced into a wide variety of environments and, through experience, learn to model the activity in that environment. The PDM framework infers as …

Attribution Standardization for Integrated Concurrent Engineering
… parametric CAD systems, Product Data Management (PDM) systems were developed to capture, document, and manage each product revision. PDM has proved effective thus far at managing design history. However, PDM is built upon database management systems (DBMS), which have the capability of doing far …

Flow estimation for stream restoration and wetland projects in ungaged watersheds using continuous simulation modeling
… In this study the Probability Distributed Model (PDM), was generalized for the Maryland and Virginia Piedmont. Two hundred and sixty years of daily average flow data from fifteen watersheds were used to calibrate PDM. Because the application of the study is to stream restoration, the model was …
