|
 | The need for taxonomic understanding and the ability to identify bloodsucking disease vectors is too often taken for granted by medical and veterinary officers directing efforts in disease control. Overseas experience has shown that an essential for all epidemiological studies is a good taxonomic knowledge of the organisms under study, whether they be the vectors or the infective agents. Starting in 1957, we began gathering the taxonomic material in preparation ... |

|
| In the first year of funding our research focused on classification tasks under uncertainty, with special emphasis on propagating beliefs in a system containing a mixture of categorical and probabilistic relationships. Previously available techniques were able to handle taxonomic trees, where the main relationship is ISA--i.e., class membership. The knowledge involved in object recognition contains non-binary relationships (e.g., IN-BETWEEN) arranged in non-decomposable structures. The difficulties encountered stem from the incompleteness ... |

|
| The psychomotor ability literature was reviewed to determine the validity and potential usefulness of psychomotor ability tests for personnel selection and classification. Over 2,200 psychomotor test validity coefficients were located. These were tabulated by ability (using Fleishman's psychomotor ability taxonomy), criterion (e.g., school vs. training vs. job performance), and job type. Analyses of these data showed that psychomotor tests had been used successfully to predict training and job performance for ... |

| Questions concerning individual differences in learning ability may be more precisely addressed in light of an agreed-upon taxonomy of learning skills. In this paper we review a variety of attempts to propose learning taxonomies and point out some of their limitations. We then propose a taxonomy consisting of four dimensions: learning environment (or learning process), resulting knowledge type, domain, and learning style. The first three dimensions specify a learning task, ... |

| Empirical research has investigated work performance in terms of taxonomies of abilities values and personality characteristics. However, until recently little research has focused on developing environmental taxinomies or examining relationships between these factors and performance criteria. Although field studies have supported associations between environmental variables and affective reaction to the job, these variables have shown only weak and inconsistent relationships with performance ratings. In this research, a 14- dimension environmental ... |
