Quaternary geology of the Campbellford, Trenton, Consecon, Tweed, Belleville, Wellington, Sydenham, Bath, and Yorkshire Island map-areas, Ontario /

Sediment relationships observed during geological mapping in southeastern Ontario indicate a relatively simple deglaciation history for the area during late Wisconsin time. The ice from the north (part of the Lake Simcoe lobe) and the Lake Ontario ice lobe, which were coalesced during most of late Wisconsin time, initially separated along the crest of the Oak Ridges Moraine. Available data indicate that the Oak Ridges Moraine is composed primarily of sediments pre-late Wisconsin in age capped by late Wisconsin till and interlobate deposits. Retreat of the northern ice was relatively steady and resulted in the deposition of the Dummer Moraines, a facies of the drumlinized till to the south. Retreat of the Lake Ontario ice lobe into the Lake Ontario basin was interrupted by a re-advance which covered the southeastern half of the map area. The northern ice had already retreated from the area by this time. The Lake Ontario lobe was fed through the St. Lawrence Valley, indicating that the Ottawa Valley was ice filled at this time. High level glacial lakes fronted the ice during deglaciation. These waters quickly fell to low levels as the ice retreated from the St. Lawrence Valley, opening lower outlets.

The effect of pH and ethanol on the astringent sub-qualities of red wine, and the implications for optimum grape maturity /

The first objective of this study was to identify appropriate sensory descriptors to assess the astringent sub-qualities of red wine. The influence of pH and ethanol on the sensation of astringency in red wine was evaluated, using a de-alcoholized red wine. A portion of the wine was adjusted to the pH values of 3.2, 3.4, 3.6 and 3.8, and another portion was adjusted to ethanol concentrations of 0%, 6%, 12%, and 15%. In addition, the pH 3.4 and 3.6 treatments were adjusted to an ethanol concentration of 12% and 15% all wines were then assessed sensorially and seventeen terms were identified, through panel discussion, to describe the mouth-feel and taste qualities: velvet, aggressive, silk/satin, dry, fleshy, unripe, pucker viscosity, abrasive, heat, chewy, acidity, grippy/adhesive, bitter, balance, overall astringency, and mouth-coat. Descriptive analysis profiling techniques were used to train the panel and measure the intensity of these attributes. It was found that decreasing pH values (averaged across all ethanol concentrations) showed an increase in the overall astringency of the wine. The combined treatments of ethanol and pH, real wine parameters (pH 3.4 and 3.6; 12% and 15% ethanol) did not have an effect on the perception of the astringent sub-qualities of the wine. A time intensity study was also included using the pH and ethanol adjusted wines, which showed that as the ethanol level of the wines increased so did the time to maximum intensity. The second objective was to identify appropriate sensory descriptors to evaluate the influence of grape maturity and maceration technique (grape skin contact) on the astringency sub-qualities of red vinifera wines from Niagara. The grapes were harvested across two dates, representing an early harvest and a late harvest. A portion of the Cabernet Sauvignon grapes wine was divided into three maceration treatments of oneweek maceration, standard two-week maceration, three-week maceration, and MCM. Another portion of both the early and late harvest Cabernet Sauvignon grapes were chaptalized to yield a final ethanol concentration of 14.5%. The wines were assessed sensorially and thirteen terms were identified, through panel discussion, to describe the mouth-feel and taste qualities: carbon dioxide, pucker, acidity, silk/chamois, dusty/chalky/powdery, sandpaper, numbing, grippy/adhesive, dry, mouthcoat, bitter, balance and, overall astringency. Descriptive analysis techniques were used to train the panel and measure the intensity of these attributes. The data revealed few significant differences in the mouth-feel of the wines with respect to maturity; which included differences in overall astringency and balance. There were varietal differences between Cabernet Sauvignon, Cabernet Franc, and Pinot Noir and differences for Cabernet Sauvignon wines due to the length and manner of maceration and as a result of chaptalization. Statistical analysis revealed a more complex mouth-feel for the Pinot Noir wines; and an increase in the intensity of the astringent sub-qualities as a result of the addition of sugar to the wines. These findings have implications for how processing decisions, such as optimum grape maturity and vinification methods may affect red wine quality.

Effectiveness of life skills training on the total behaviour of six individuals in a job preparation program

In the first week of a Job preparation Program all twelve female members of the class were invited to be part of a study to determine the effect of Life Skills training on their behaviour over the twelve-week period of the program. Six females volunteered and each was interviewed four times during the Job preparation Program and once after the program ended. The interviews focused on three areas of skill deficiency addressed in Life Skills lessons: their knowledge about themselves and attitude towards themselves; their interpersonal relationships; and their problem-solving ability. The participants' comments over the sixteen-week period of the interviews were used to decide if the total behaviour of the participants, (i.e., what they did, thought, and felt) changed so that each became more effective in satisfying her needs. The study suggested that the total behaviour of three of the six women changed so that they became more effective in satisfying their needs. The fourth female's total behaviour changed in only two of the three areas focused on in the interviews, and the total behaviour of the fifth and sixth females showed no change.

Improving the use of the nursing process: the impact of charting methodology developed from King's conceptual framework on the use of the nursing process

The purpose of this study was to assess the effects of changing a nursing documentation system, developed from King's Conceptual Framework, on the use of the nursing process. The null hypothesis was that there would be no significant increase in the reflection of the use of the nursing process on the nursing care plan or nurses' notes, as a result of using a nursing documentation system developed using King's Conceptual Framework (1981). The design involved the development of a questionnaire that was used to review health records pre and post implementation of a documentation system developed based on King's Conceptual Framework and Theory of Goal Attainment (1981). A Record Completeness Score was obtained from some of the questions. The null hypothesis was rejected. The results of the study have implications for nursing administration and the evaluation of nursing practice. If the use of a documentation system developed from a conceptual framework increases the reflection of the nursing process on the patient's health record, nursing will have the means to measure patient outcomes/goal attainment. All health care organizations and levels of government are focusing on methods to monitor and control the health-care dollar. In order for nursing to clearly determine the costs associated with nursing care, measurement of patient outcomes/goal attainment will need to be possible. In order to measure patient outcomes/goals attainment nurses will need to be able to collect data on their practice. It will be critical that nursing have a documentation system in place which facilitates the reflection of the nursing process within a theoretical framework.

The effects of teaching a mathematics problem solving strategy on the problem solving ability of grade nine students

Forty grade 9 students were selected from a small rural board in southern Ontario. The students were in two classes and were treated as two groups. The treatment group received instruction in the Logical Numerical Problem Solving Strategy every day for 37 minutes over a 6 week period. The control group received instruction in problem solving without this strategy over the same time period. Then the control group received the treat~ent and the treatment group received the instruction without the strategy. Quite a large variance was found in the problem solving ability of students in grade 9. It was also found that the growth of the problem solving ability achievement of students could be measured using growth strands based upon the results of the pilot study. The analysis of the results of the study using t-tests and a MANOVA demonstrated that the teaching of the strategy did not significaritly (at p s 0.05) increase the problem solving achievement of the students. However, there was an encouraging trend seen in the data.

Teachers' perspectives on the implementation of expectations-based curricula /

This qualitative study examines teachers' experiences implementing new standardized curricula in Ontario schools. This new curricula contained several policy changes and an expectations based format which directed what knowledge and skills students were to demonstrate in each subject. This level of specificity of subject-content served to control teachers in relation to curricula; however, data suggested that at the same time, teachers had enormous flexibility in terms of pedagogy. Four secondary teachers who were implementing a Grade 10 course in the 2000-2001 school year participated in the study. The qualitative framework supported the researcher's emphasis on examining the participants' perspectives on the implementation of expectation-based curricula. Data collected included transcripts from interviews conducted with teacher participants and a representative of the Ontario Ministry of Education and Training, field notes, and a research journal. Many of the factors often cited in the literature as influencing implementation practices were found to have affected the participants' experiences of curriculum implementation: time, professional development, and teachers' beliefs, particularly concerning students. In addition, the format of the policy documents proved to both control and free teachers during the implementation process. Participants believed that the number of specific expectations did not provide them an opportunity to add content to the curriculum; at the same time, teachers also noted that the general format of the policy document allowed them to direct instruction to match students' needs and their own teaching preferences. Alignment between teachers' beliefs about education and their understanding of the new curriculum affected the ways in which many participants adapted during the implementation process.

An exploration of the impact of a mandatory quality assurance program on the staff nurse's commitment to professional development /

This study explored experiences in relation to the impact of the College of Nurses of Ontario's (CNO's) mandatory Quality Assurance (QA) program on registered nurses (RNs) working in a clinical setting of an acute care hospital. A qualitative descriptive research design was used and data collection was done in 2 stages. First, a survey with open-ended questions was given to 45 nurses. Second, 8 respondents from the survey were interviewed using a semistructured format. Data were obtained from 2 groups-diploma-prepared and post diploma-prepared RNs. Findings demonstrated that the CNO's QA program had varying influences on the RNs' learning paths, and these differences appeared to be related to the educational background of the individual. The diploma-prepared nurses reported that their commitment to professional development was influenced by their level of internal motivation, the pressures associated with time, and the need for a strong external motivator, namely the obligation of management to conduct formal performance appraisals. They further reported that the QA program played a part in positively altering their commitment to continuing education. The post-diploma baccalaureate nurses reported that the QA program played a positive role in influencing their ongoing learning, along with their level of internal motivation, the work and health care environment, and the element of professionalism. Several implications for nursing practice, theory, and fiirther research also became evident.

The influence of physical activity behaviour on the relationship between motor proficiency and body composition in children

There is an emerging awareness that children with poor motor abilities are at particular risk for overweight. This cross-sectional study examined the influence of physical activity behaviour on the relationship between motor proficiency and body composition. Participants were 1287 (646 males, 641 females) Grade 6 students in the Physical Health Activity Study project. Height, weight, waist girth, and motor proficiency (Bruininks-Oseretsky Test of Motor Performance BOTMP-SF) were assessed. Physical activity behaviours were also evaluated with a multifaceted approach and reported for school-based, non-school based physical activity, free-time play, and sedentary activities (Participation Questionnaire), and leisure time exercise (Godin-Shephard Leisure Time Exercise Questionnaire GS). Overweight was defined by BMI scores: boys :::20.6-21.2 and <25.1-26.0; girls: ::: 20.7-21.7and <25.4-26.7 and obesity was defined as: boys:::: 25.1-26.0; girls: :::25.4-26.7. Children were classified as case group (CG,::; 10% on BOTMP-SF), borderline case group (BC, > 10% to ::; 20% on BOTMP-SF) or non-case group. Analyses of variance (ANOVAs) uncovered a significant difference in overweight and obesity between the case group and non-case group. Normal-weight children reported higher participation in organized school-sports (intra-mural and inter-school teams). The CG reported significantly lower participation in school sports teams and lower GS results, with a trend towards lower participation in all active pursuits. They also reported a significantly higher duration of television watching and book reading. There were no significant differences between motor proficiency groups by gender, age, nonschool sports, or free-time activity. Multivariate ordinal logistic regression analysis showed that the case group was 10.9 times more likely to be overweight/obese than their peers. No single aspect of physical activity was able to explain the difference in odds ratios for the motor proficiency groups. However, for the entire cohort, children who participated in more organized school sports were less likely to be overweight/obese. These findings confirm that children with low motor proficiency are at significant risk of developing overweight. It is evident that these children have generally attenuated activity levels and heightened levels of sedentary pursuits. School-based activities appear particularly limited, and are the one area where children have near autonomy in their decision to pursue active opportunities. The promotion of school-based programs, specifically intramural sports may be an important aspect in increasing children's overall activity levels. It is also essential to consider the needs of those children with low motor proficiency when designing activity promotion programs. Future research should further explore motor proficiency and overweight/obesity.

Bullying in physical education : its prevalence & impact on the intention to continue secondary school physical education

The purpose of this study was to determine the prevalence of bullying in physical education and its influence on students' intention to participate in the class in the future. Additionally, the study researched the relationship between bullying and body image as well as bullying and physical competency in physical education. A survey was utilized that collected both quantitative and qualitative data about students' experiences in physical education. Two-hundred and thirty-four grade 10 students (144 female and 90 male) from 8 different secondary schools participated in the study. Data analyses were completed using the Statistical Package for the Social Sciences (SPSS) version 16.0. Results showed thaLapproximately 18.3% of respondents had .experienced physical bullying in physical education; 23.7% had experienced verbal bullying; and 20.4% experienced social bullying. Furthermore, those who experienced frequent bullying in physical education did not intend on taking the class in the future. The relationship between body image and bullying was not found to be significant. However, physical competence was found to significantly predict bullying in physical education. These results show how prevalent bullying is in physical education classes and how it negatively impacts future participation in the class.

Examining the inclusion experiences of students with intellectual disabilities : a study focusing on the transition from elementary to secondary school

Transitioning from elementary to secondary school is a major event in adolescents' lives and can be associated with academic, social, and emotional challenges (Shaffer, 2005; Sirsch, 2003). Considerably less research has focused on the transitional experiences of students with intellectual disabilities (lD) as they enter secondary school and the role of educational inclusion in this process (Noland, Cason, & Lincoln, 2007). Conceivably, students with ID who leave inclusive elementary schools, where they have been educated alongside their peers without ID, and who enter segregated secondary educational placements may experience unique social and emotional challenges (Farmer, Pearl, & Van Acker, 1996; Fryxell & Kennedy, 1995; Shaffer, 2005). This study examined the transitional experiences of 6 students with ID and the role of educational inclusion, with a focus on elementary to secondary school transitions from inclusive to segregated settings and vice versa. This study included the collection of multiple sources of data. Semi-structured interviews with 6 caregivers and students with ID were conducted. Students' Individual Education Transitional Plans were discussed in caregivers' interviews to determine how they shaped students' educational inclusion experiences (Ontario Ministry of Education & Training, 1999/2000/2004). Parts ofthe following questionnaires were "qualitized" (Tashakkori & Teddlie, 1998) and administered orally: "Youth Self-Report" (YSR; Achenbach, 2001 c) and "Child Behaviour Checklist Caregivers Form" (CBLC/6-18; Achenbach, 200la). The findings of this study contribute to the literature on educational inclusion by highlighting the positive/negative social and emotional impact of congruent and incongruent transitional experiences of students with ID and the role of educational inclusion.

Freshwater dinoflagellates as proxies of cultural eutrophication: a case study from Crawford Lake, Ontario

Crawford Lake, Ontario, provides an ideal natural laboratory to study the response of freshwater dinoflagellates to cultural eutrophication. The anoxic bottom waters that result from meromixis in this small (2.4 ha) but deep (24 m) lake preserve varved sediments that host an exceptional fossil record. These annual layers provide dates for human activity (agriculture and land disturbance) around the lake over the last millennium by both Iroquoian village farmers (ca. A.D. 1268-1486) and Canadian farmers beginning ~A.D. 1883. The well established separate intervals of human activity around Crawford Lake, together with an abundance of available data from other fossil groups, allow us to further investigate the potential use of the cyst of freshwater dinoflagellates in studies of eutrophication. Cyst morphotypes observed have been assigned as Peridinium willei Huitfeldt-Kaas, Peridinium wisconsinense Eddy and Peridinium volzii Lemmermann and Parvodinium inconspicuum (Lemmermann) Carty. The latter two cyst-theca relationships were determined by culturing and by the exceptional preservation of thecae of P. inconspicuum in varves deposited at times of anthropogenic reductions in dissolved oxygen.

An Exploration Into Doctoral Students' Sense of Community and its Influence on the Formation of Informal Mentoring Relationships

This exploratory mixed method research project was designed to investigate an area of doctoral education that has received little attention in the past. This research focused specifically on the non-intellectual, hoped-for by-products of doctoral education; the dynamic processes of developing and maintaining both a sense of community and informal mentoring relationships. The design of the study captured the experiences of doctoral students and alumni at various time periods in the doctoral program. Participants represented a diverse group of students with differences in professional and academic backgrounds and life stages. A pilot study for this research suggested that the presence of a sense of community and informal mentoring may provide the necessary relationships to support this diversity. The primary question at the forefront of this study was: Do doctoral students feel connected to one another? Five subquestions were developed to address this research topic: Does a sense of community already exist and flourish in doctoral education? Are the programs and resources of the doctoral program organized to nurture the creation and maintenance of a sense of community? Is a sense of community a foundational element in the formation of naturally occurring relationships among doctoral students? What educational and socio-emotional benefits are associated with informal mentoring relationships during the doctoral experience? and Do doctoral students perceive a change in their development as stewards of their discipline over time? The principal methods used to investigate these research questions combined both quantitative and qualitative techniques in a concurrent time sequence. The quantitative portion of the study involved a questionnaire, while the qualitative portion involved two approaches; face-to-face interviews and an open-ended question at the end of the questionnaire. Findings from the study indicated that the presence of both sense of community and informal mentoring enhance the overall quality of doctoral education. Program elements that enhanced or hindered connection between students were identified. Both the dynamics and the emotional, social, and academic benefits of informal mentoring were elucidated. Over time participants perceived changes in their development of the qualities assqciated with stewardship. This study brought the "hoped-for by-products" associated with doctoral education from the background shadows to an illuminated position at the forefront of inquiry.
