Classification of learning disabilities: Old problems and new approaches.

There is an increasing awareness of problems with traditional classifications and definitions of learning disabled children. This article briefly reviews the conceptual and operational limitations of classic approaches. New classification research with learning disabled populations is investigating alternative classification schemes through systematic and empirical hypothesis-testing paradigms. Such research has sparked renewed interest in learning disability subtypes, developmental factors in learning, and remediation strategies. Only through the development of more reliable and valid classification will many of the present problems in clinical and research endeavors with learning disabled children be addressed.

Issues in the use and interpretation of discriminant analysis.

Reviews the 2 problems for which a discriminant analysis is used—separation and classification. Issues related to the use and interpretation of a discriminant analysis are those pertaining to (a) distinguishing between a linear discriminant function and a linear classification function, (b) misusing stepwise discriminant analysis programs, (c) ordering variables and selecting variable subsets, (d) choosing a classification rule, (e) estimating true classification hit rates, (f) assessing classification accuracy, and (g) examining and using classification results. Most of these issues deal with information available from package discriminant analysis computer programs. (50 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The ribonucleotide reductase inhibitor (E)-2''-fluoromethylene-2''-deoxycytidine (MDL 101,731): a potential topical therapy for herpes simplex virus infection

Recent advances in diagnosis, treatment, and tumor biology of the lymphoid blastic malignancies have challenged historical concepts and created a need for revised classification of these diseases. The authors review this material and present a classification relevant to current therapeutic protocols and available biological data. Further advances in understanding of these diseases can be anticipated, with possible further evolution of classification. The exact clinical role of sensitive studies to monitor residual disease during and after treatment remains to be established. These diseases may present difficult differential diagnostic problems. The importance of accurate diagnosis cannot be overemphasized, as highly successful but divergent treatments have evolved for these various hematopoietic diseases. Diagnostic problems are usually resolved with systematic analysis including careful morphology, cytochemistry, immunologic analysis, and addition of EM and other studies in selected circumstances.     

Motivational conflict and vocational development.

Presents a classification of the sources of motivational conflicts found in college students seeking counseling for vocational problems and their application to 82 vocational counseling cases. The major classification categories of synthetic difficulties, identity problems, gratification conflicts, change orientation, and overt pathology were derived from case notes and recent emphasis on a developmental approach to vocational choice that emphasizes personality development and treats successive choice points as transitional periods in a continuous process. Since the vocational choice task involves negotiating an integration of operating identity (needs, identification, skills, impulse-defense styles, and values) with occupational roles, the classification of motivational conflicts as a source of difficulty in vocational indecision offers a useful method for explicating issues in vocational-choice counseling. Applications to differential counseling processes are discussed. (l7 ref.) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Observer variation in the radiographic classification of fractures of the neck of the femur using Garden's system

By means of Kappa statistics, we calculated the inter- and intra-observer variation in the classification of fractures of the neck of the femur according to Garden's system. Radiographs of 96 consecutive patients were assessed independently by six observers who agreed on classification for only 14 fractures (15%). The level of agreement was poor for the overall classification (Kappa = 0.39). When reducing Garden's system into non-displaced (Stage I and II) and displaced fractures (Stage III and IV) the level of agreement became acceptable (Kappa = 0.68). However, problems remain in distinguishing Stage II and Stage III fractures, and further improvements in the classification system are necessary.     

Comment on Locke's satisfiers and dissatisfiers among white-collar and blue-collar employees.

Contends that some methodological problems limit E. A. Locke's (see record 1974-10066-001) classification system for occupational satisfiers and dissatisfiers which distinguished between agent and event categories. An alternative classification system, taking into account the multiple determination of some events, is recommended. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Bayesian Learning Using Automatic Relevance Determination Prior with an Application to Earthquake Early Warning

A novel method of Bayesian learning with automatic relevance determination prior is presented that provides a powerful approach to problems of classification based on data features, for example, classifying soil liquefaction potential based on soil and seismic shaking parameters, automatically classifying the damage states of a structure after severe loading based on features of its dynamic response, and real-time classification of earthquakes based on seismic signals. After introduction of the theory, the method is illustrated by applying it to an earthquake record dataset from nine earthquakes to build an efficient real-time algorithm for near-source versus far-source classification of incoming seismic ground motion signals. This classification is needed in the development of early warning systems for large earthquakes. It is shown that the proposed methodology is promising since it provides a classifier with higher correct classification rates and better generalization performance than a previous Bayesian learning method with a fixed prior distribution that was applied to the same classification problem.
