Brief: market research techniques--a synopsis for continuing education providers.
Any organization that attempts to attract and hold customers must face the necessity of determining what people want and value, and then cater to those wants and values (Levitt, 1983). Educational providers can use these market research techniques to strengthen the design and implementation of nursing CE offerings. In addition to alleviating the monotony of pen and paper questionnaires for our learners, these techniques can strengthen our programming by gathering a wealth of information about the qualitative and quantitative nature of the needs of our customers. The marketing knowledge gained from these tools can help to ensure the continued success of our educational endeavors despite growing fiscal constraints.
The relationship between standardized psychomotor tests and basic clinical dental hygiene skills.
PURPOSE: This study was designed to help dental hygiene educators identify predictors of early instrumentation achievement among preclinical students. Studies from other disciplines suggest that underlying abilities play a significant role in early skill development and that additional factors contribute to later skill development. Previous studies in the dental professions have not differentiated between early skill development and later skill development. METHODS: Forty-five entering dental hygiene students were subjected to six psychomotor tests. In the first trimester, these same students were given three instrumentation tests (Marquis probe, 3-A explorer, and Gracey curets) by calibrated faculty. Data from the psychomotor and the instrumentation tests were then statistically examined using means, standard deviations, Pearson product-moment correlations, and stepwise regression to determine predictive validity of the ability tests for each instrumentation skill. RESULTS: The Purdue Hand Precision Test was found to contribute significantly to use of the explorer and Gracey curets. Analysis of variance revealed that this test accounted for 17 percent of the variance on the probe examination and 22 percent on the curet examination. None of the other psychomotor tests used were predictive of early clinical skills. CONCLUSIONS: This study suggests that hand-eye coordination, precision, and aiming, as measured by the Purdue Hand Precision Test are factors in the development of early dental hygiene instrumentation skills. Continued study in this area is indicated since early identification of clinical problems may help educators and students deal with morale and retention issues.
Comparative study of colorimetric DNA hybridization method and conventional culture procedure for detection of Salmonella in foods.
A second generation nucleic acid hybridization assay has been developed and evaluated against the conventional culture method for detection of salmonellae in foods. The assay involves a liquid hybridization with Salmonella-specific oligonucleotide probes, capture of probe:target hybrids onto a solid support (plastic dipstick), and a colorimetric end point detection. The assay can be completed in 2.5 h, following approximately 44 h of culture enrichment. One thousand samples representing 20 food types were analyzed in parallel by both methods. Samples included uninoculated test product, and product inoculated with Salmonella at 2 levels. Eighteen Salmonella serotypes were used as inocula. The data demonstrate that the colorimetric hybridization method and the conventional culture method are equivalent in their ability to detect Salmonella contamination of foods.
