Fifteen mentoring pairs of teachers were randomly selected from each group of teachers that had participated in the Halton Board of Education "Partners in the Classroom" program during 1988/89, 1989/90, and 1990/91. Each teacher was personally interviewed. Interviews were recorded, transcriptions were prepared and examined and analyzed. During the first part of the interview questions were asked regarding personal and professional demographics. The purpose of the second part of the interview was to gain information relating to the development of the relationships, over a three-year period, between mentor and mentee teacher participants in the "Partners in the Classroom" program. The analysis of the data suggest that there are identifiable changes in the development of the relationship between the mentor teacher and the mentee teacher over time. Implications from the study results that could enhance the induction program for new teachers are discussed.

Identification of larval simuliids has always been difficult due to the morphological similarity many species bear to one another. For this reason all characters available have been drawn upon to aid in species identification, including head fan ray number. Even in light of an increasing body of anecdotal reports that head fan ray number is not fixed, it has continued to be used to aid species identification. In the current experiment simuliid larvae were reared under controlled laboratory conditions to last instar in one of three feeding regimes. Out of nine trials, the results of six showed a significant inverse relationship between feeding regime and head fan ray number. In addition to the laboratory experiments, larvae were also collected from the field over the course of the spring and summer, 1994. From these samples significant interspecific and intraspecific variations in head fan ray number were found both spatially and temporally within Algonquin Park. From these data it is concluded that head fan ray number for the species analysed is a developmentally plastic character, which varies in response to food availability. Furthermore, given the extreme variations in head fan ray number found in some species, I recommend that head fan ray number not be used as an aid to identification unless it can be shown to be a fixed character for the species in question.

This study examined patterns of psychotropic medication use among 120 participants with intellectual disabilities (ID) who used to live in facilities and now reside in community-based settings in Ontario. There were significantly more participants taking psychotropic medication in the community (83.30/0) than in the facility (74.2%). Of those who showed change, 4.2% were taking medication in the facility but not in the community, and 13.3% were taking medications in the community but not in the facility. While significantly more participants in the community were taking antipsychotic and antidepressant medications, there was no significant increase in psychiatric diagnoses after relocation. Additionally, PRN use was significantly reduced in the comlnunity while daily medication use was significantly higher. The most common PRN in both settings was lorazepam and the most common antipsychotics were risperidone, quetiapine and olanzapine.
