A Guide for Studying the Personality of a Young Child

Five methods for analyzing data arising from research involving pretests and posttests are considered. These methods include: (1) posttest analysis only; (2) analysis of raw gain scores (posttest minus pretest); (3) analysis of the data with a pretest-posttest factor included in the statistical model; (4) analysis of posttest data with pretests as a covariate, and (5) analysis of gain scores with pretests as a covariate. The characteristics of each are discussed, with a conclusion that the fifth method is superior to the others when the assumptions underlying covariance analysis are met.     

Using volunteers in Ontario hospital libraries: views of library managers.

BACKGROUND: Volunteers have been a resource for all types of libraries for many years. Little research has been done to describe the attitudes librarians have toward library volunteers. More specifically, the attitudes of hospital librarians toward volunteers have never been studied. OBJECTIVE: The objective was to explore and describe the extent of volunteer use and to determine library managers' attitudes toward volunteers. DESIGN, SETTING, AND PARTICIPANTS: An anonymous, self-report 38-item questionnaire was mailed to the target population of 89 hospital library managers in Ontario. Seventy-nine useable questionnaires were analyzed from an adjusted sample of 86 eligible respondents, resulting in a response rate of 92%. SPSS 11.5 was used to analyze the data. FINDINGS: The data revealed the attitudes of managers using volunteers did not differ significantly from the attitudes of managers not using volunteers. The findings showed that a majority of managers did not believe their libraries were adequately staffed with paid employees. Sufficient evidence was found of an association between a manager's belief in the adequacy of staffing in the library and the use of volunteers in the library (chi2(1, N=76)=4.11, P=0.043). Specifically, volunteers were more likely to be used by managers who did not believe their libraries were adequately staffed. The presence of a union in the library and the use of volunteers were also associated (chi2(1, N=77)=4.77, P=0.029). When unions were present in the library, volunteers were less likely to be used. IMPLICATIONS: This research has implications for hospital library managers in the management of volunteers. Volunteers should not be viewed as a quick fix or as a long-term solution for a library's understaffing problem.
