Taxonomic Analysis of Marine Actinomycetic Isolates

Description: Though this current study was initiated independently and was not a test laboratory for the taxonomic sub-committee's evaluative program, the problem outlined in this treatise was also designed in an effort to test certain characteristics of the actinomycetes of both a biochemical and morphological nature. This problem employed methods that might absolve or establish certain criteria for taxonomic use in the group of actinomycetes.

Mathematical Programming Approaches to the Three-Group Classification Problem

Description: In the last twelve years there has been considerable research interest in mathematical programming approaches to the statistical classification problem, primarily because they are not based on the assumptions of the parametric methods (Fisher's linear discriminant function, Smith's quadratic discriminant function) for optimality. This dissertation focuses on the development of mathematical programming models for the three-group classification problem and examines the computational efficiency an… more

Impact of Job Classification Level on Perceived Empowerment Level in a Work Setting

Description: Empowerment, which has been described as both a means of effecting higher and more efficient quality work outputs and a means of facilitating greater freedom in the workplace combines elements of philosophy, psychology, and management theory. The perceptions of the present empowerment level of 3500 employees of a division of a major corporation were analyzed using data from an empowerment survey. The results were examined using correlational and factorial measures to test the structure of the s… more

The Classification and Grading of Cotton

Description: "The objects of grading and classifying cotton are to aid (1) in determining the comparative values of the different qualities and (2) in describing the cotton so as to make buying and selling easier when there are no samples. With the present methods of buying cotton...the grade practically determines the price that is received by the producer." -- p. 1-2. The bulletin introduces the grades by name, explains the factors that influence the grade, discusses grade standards, and provides cost and… more

Conducting Floristic Studies of Local Plant Populations: The Potential of Two-Year College Students and Faculty

Description: The purpose of this research was to evaluate the ability of two-year college students and faculty in one area of activity and to gain a more adequate understanding of them. A dearth of taxonomic literature on plant populations at the local level prompted this study. It has been observed that amateur botanists have accomplished satisfactory and commendable work in plant taxonomy. Also, it has been observed that a high percentage of students in two year colleges commute considerable distances. Th… more

An Approach Towards Self-Supervised Classification Using Cyc

Description: Due to the long duration required to perform manual knowledge entry by human knowledge engineers it is desirable to find methods to automatically acquire knowledge about the world by accessing online information. In this work I examine using the Cyc ontology to guide the creation of Naïve Bayes classifiers to provide knowledge about items described in Wikipedia articles. Given an initial set of Wikipedia articles the system uses the ontology to create positive and negative training sets for the… more

Classification by Neural Network and Statistical Models in Tandem: Does Integration Enhance Performance?

Description: The major purposes of the current research are twofold. The first purpose is to present a composite approach to the general classification problem by using outputs from various parametric statistical procedures and neural networks. The second purpose is to compare several parametric and neural network models on a transportation planning related classification problem and five simulated classification problems.

The Effect of Certain Modifications to Mathematical Programming Models for the Two-Group Classification Problem

Description: This research examines certain modifications of the mathematical programming models to improve their classificatory performance. These modifications involve the inclusion of second-order terms and secondary goals in mathematical programming models. A Monte Carlo simulation study is conducted to investigate the performance of two standard parametric models and various mathematical programming models, including the MSD (minimize sum of deviations) model, the MIP (mixed integer programming) model … more

The Psychiatric Rating Scale for Diagnostic Classification of Children and Adolescents Interrater Reliability

Description: This study was designed to assess the reliability of "The Psychiatric Rating Scale for Diagnostic Classification of Children and Adolescents" as an instrument for determining diagnoses congruent with DSM-III criteria. In Phase I graduate students from a University doctoral program in psychology independently rated case vignettes and completed the 64-item rating scale to arrive at Axis I or II diagnoses consistent with DSM-III classifications for Disorders Usually First Evident in Infancy, Child… more

Automatic Extraction of Grasses and Individual Trees in Urban Areas Based on Airborne Hyperspectral and LiDAR Data

Description: This article proposes a three-dimensional (3D) vegetation extraction workflow to extract urban grasses and trees at individual tree level in urban areas using airborne LiDAR and hyperspectral data. Results suggest that two- and three-dimensional urban vegetation extraction could play a significant role in spatial layout optimization and scientific management of urban vegetation.

The Identification and Explication of a Typology of Adolescents' Leisure Functioning

Description: This study involved the identification and explication of a typology of adolescents' leisure functioning, based on a state of mind definition of leisure. Subjects included 200 students from a junior high school in the midwest who completed the Leisure Diagnostic Battery (LDB) during a study hall. Procedures involved the application of two methods of cluster analysis to profiles of scores across the five LDB scales which are designed to measure perceived freedom in leisure. Following this proces… more

A Comparative Study of Water Indices and Image Classification Algorithms for Mapping Inland Surface Water Bodies Using Landsat Imagery

Description: This article presents a comparative study of water indices and image classification algorithms for mapping inland water bodies using Landsat imagery through obtaining 24 high-resolution (≤5 m) and cloud-free images archived in Google Earth with the same (or ±1 day) acquisition dates as the Landsat-8 OLI images over 24 selected lakes across the globe, and developing a method to generate the alternate ground truth data from the Google Earth images for properly evaluating the Landsat image classif… more

Interrater Reliability of the Psychological Rating Scale for Diagnostic Classification

Description: The poor reliability of the DSM diagnostic system has been a major issue of concern for many researchers and clinicians. Standardized interview techniques and rating scales have been shown to be effective in increasing interrater reliability in diagnosis and classification. This study hypothesized that the utilization of the Psychological Rating Scale for Diagnostic Classification for assessing the problematic behaviors, symptoms, or other characteristics of an individual would increase interra… more

Simple Fully Automated Group Classification on Brain fMRI

Description: We propose a simple, well grounded classification technique which is suited for group classification on brain fMRI data sets that have high dimensionality, small number of subjects, high noise level, high subject variability, imperfect registration and capture subtle cognitive effects. We propose threshold-split region as a new feature selection method and majority voteas the classification technique. Our method does not require a predefined set of regions of interest. We use average acros sses… more
