This dissertation concerns two topics in the analysis of finite population surveys:
setting sample size and hypothesis testing. The first concerns the a priori determination
of the sample size needed to obtain species members. The second concerns
testing distributional hypotheses when two equal-size populations are sampled.
Setting sample size to...
Evaluating the success or failure of work force training programs is most often accomplished through the reporting of "objective" data. Rarely are the students' views of their own success in such a training program formally solicited or applied in any useful way. But participant perceptions can be a critical barometer...

of prey, and competition with ants as factors influencing the abundance and community
composition of arboreal spiders in western Oregon.
In 1993, I compared the spider communities of several host-tree species which
have different branch structure. I also assessed...
