The use of an overall F test to control Type I error rates in factorial analyses of variance: limitations and better strategies
Article Abstract:
The inflation of Type I error rates caused by the testing of multiple null hypotheses in factorial analyses of variance (ANOVAs) is a problem that is often not recognized in the behavioral sciences. Fletcher, Daw, and Young (1989) described the problem and conducted a limited simulation study to ivestigate the effectiveness of two strategies to correct the problem: use of an overall F test and use of a Bonferroni adjustment. Unfortunately, two limitations in the design of their simulation led these authors to conclusions about the overall F test that do not hold under all conditions. Thes present study was designed to overcome these limitations and to provide a more complete evaluation of such strategies. Our results indicated that the overall F test is effective only when all effects in the ANOVA are null. In contrast, the Bonferri adjustment and recent modifications of the procedure control and the Type I error rate regardless of the number of true null hypotheses in the ANOVA.

Rhetoric and policy realities in developing countries: community councils in Jamaica, 1972-1980
Article Abstract:
The relationship between rhetoric and policy in developing countries is examined using a case study drawn from the administration of Michael Manley in Jamaica in the 1970s. Particular attention is paid to problem definition, policy formulation, and implementation processes. The policy relating to community councils was based on socialistic political and economic arguments. Despite minor successes, most of the objectives associated with the community councils policy were not realized. This failure was due, we suggest, to the Manley government's inability to transcend electoral and economic (national and international) realities and to convince a majority of the public and opposition of the validity of its rhetorical constructions. Parallels to three other developing countries are briefly explored. (Reprinted by permission of hte publisher.)

The researcher, the topic, and the literature: a procedure for systematizing literature searches
Article Abstract:
Currently, no systematic procedure exists for ensuring the range and representativeness of publications included in a search of literature on a research topic. Using the logic of fieldwork methods, this article suggests such a procedure. The research topic is viewed as a "sensitizing concept," and publications and authors are identified as "sites" and "informants," respectively. Snowball sampling allows the researcher to build a sampling frame of publications. "Key" sites and informants are identified using consensual and "gatekeeper" validation criteria. These key sites and informants are subjected to careful reading resembling content analysis. (Reprinted by permission of the publisher.)
