Desired learning outcomes for the curricula in financial services industry as perceived by professionals in the financial services industry located in the Greater Toronto Area /

This study sought to explore the changing nature of the financial services industry in Toronto, Canada and the impact that these changes will have on the vocational educational outcomes required by Ontario Colleges of Applied Arts and Technology (CAAT) graduates who wish to enter the financial services industry. The study was descriptive and exploratory, based on both quantitative and qualitative data. Triangulation of 3 data sources (a collection of newspaper articles from the Toronto Star between July 1999 and June 2000, the calendars of the 25 CAATs, and a survey questionnaire prepared by me and distributed to subject matter experts who are key practitioners in the financial services industry) was used. The study contains a discussion of how the financial services industry is changing. The first question to be answered was: What do current practitioners in financial services perceive to be the knowledge, skills, and attitudes that will be required of future graduates for employment within the financial services industry? The study found that Ontario CAAT's graduates entering the financial services field need both business and financial services vocational learning outcomes. Colleges should have 2 programs 1 in accounting and 1 in financial services. The report addresses which specific topics should be included in the financial services program. The second question to be answered was: How does this anticipated profile of knowledge, skills, and attitudes change depending on the degree of implementation of the new technologies by the survey respondent? The study found no pattern. The third question to be answered was: In what way do existing programs need to change in the area of accreditation as perceived by the respondents? The study found that for accreditation, 3 credentials should be addressed within the financial services program. These are the Canadian Securities, the Life Underwriters, and the Certified Financial Planner designations. The last question to be answered was: What new knowledge, skills, and attitudes need to be incorporated into college curricula to address changing needs in the employment sector? For each Ontario CAAT which has a financial services program (excluding accounting), their program was reviewed in light of the topics as perceived by professionals in the financial services industry.

The acute effects of differential dietary fatty acids on PDHa activity in human skeletal muscle at the onset of exercise

Pyruvate dehydrogenase (PDH) is an important regulator of carbohydrate oxidation during exercise and its activity can be down-regulated by an increase in dietary fat. The purpose of this study was to determine the acute metabolic effects of differential dietary fatty acids on the activation of PDH in its active form (PDHa) at rest and at the onset of moderate-intensity exercise. University-aged male subjects (n=7) underwent 2 fat loading trials spaced at least 2 weeks apart. Subjects consumed saturated (SFA) or polyunsaturated (PUFA) fat over the course of 5 hours. Following this, participants cycled at 65% VO2 max for 15 min. Muscle biopsies were taken prior to and following fat loading and at 1 min exercise. Plasma free fatty acids increased from 0.15 ± 0.07 to 0.54 ± 0.19 mM over 5 hours with SFA and from 0.1 1 ± 0.04 to 0.35 ±0.13 mM with PUFA. PDHa activity was unchanged following fat loading, but increased at the onset of exercise in the SFA trial, from 1 .4 ± 0.4 to 2.2 ± 0.4 /xmol/min/kg wet wt. This effect was negated in the PUFA trial (1 .2 ± 0.3 to 1 .3 ± 0.3 pimol/min/kg wet wt.). PDH kinase (PDK) was unchanged in both trials, suggesting that the attenuation of PDHa activity with PUFA was a result of changes in the concentrations of intramitochondrial effectors, more specifically intramitochondrial NADH or Ca^*. Our findings suggest that attenuated PDHa activity participates in the preferential oxidation of PUFA during moderateintensity exercise.

A cognitive schematic paradigm for expository essay writing in secondary schools

The methodology outlined in this study for teaching exposit ory writing to advanced (five year phase) grade eleven students is based on the assumption that writing as a problem solving strategy is a high level cognitive skill . In adhering to this assumption, a cognitively based schematic organizer known as a cross-classification chart was tested for its effectiveness a t the planning stage of the writing process . Results were not significant in any of the three components that were evaluated; however , a post- hoc analysis undertaken because of recorded observed data indicated a significant difference in the mean score on the Organization component for the treatment subgroup using the cross- classification organizer . Furthermore, the treatment group's positive response from the attitude survey towards planning writing is encouraging enough that replication and extension of the application of schema theory to wri ting should be pursued in cross-section and longitud i nal studies.

Investigation of the Expression of Glucose Transporter Proteins in Human Cancer Cells

Cancer cells are known to display increased glucose uptake and consumption. The glucose transporter (GLUT) proteins facilitate glucose uptake, however, their exact role in cancer metabolism remains unclear. The present study examined mRNA and protein expression of GLUT1, GLUT3, GLUT4 and GLUT12 in lung, breast and prostate cancer cells and corresponding noncancerous cells. Additionally, GLUT expression was determined in tumours from mice xenografted with human cancer cells. Differences in the mRNA and protein expression of GLUTs were found between cancerous and corresponding noncancerous cells. These findings demonstrate abundant expression of GLUT1 in cancer and highlight the importance of GLUT3 as it was expressed in several cancer cells and tumours. GLUT expression patterns in vitro were supported by the in vivo findings. The study of GLUT protein expression in cancer is important for understanding cancer metabolism and may lead to identification of biomarkers of cancer progression and development of target therapies.

A Survey of hMLH1 mRNA Splicing Profiles in Human Cell Lines: Comparing Primary Cultured Fibroblasts Before and After Oxidative Stress and Transiently versus Stably Demethylated Colon Cancer Derived Cell Lines

Most human genes undergo alternative splicing and loss of splicing fidelity is associated with disease. Epigenetic silencing of hMLH 1 via promoter cytosine methylation is causally linked to a subset of sporadic non-polyposis colon cancer and is reversible by 5-aza-2' -deoxycytidine treatment. Here I investigated changes in hMLHI mRNA splicing profiles in normal fibroblasts and colon cancer-derived human cell lines. I established the types and frequencies of hMLHI mRNA transcripts generated under baseline conditions, after hydrogen peroxide induced oxidative stress, and in acutely 5-aza-2' -deoxycytidine-treated and stably derepressed cancer cell lines. I found that hMLHI is extensively spliced under all conditions including baseline (50% splice variants), the splice variant distribution changes in response to oxidative stress, and certain splice variants are sensitive to 5- aza-2' -deoxycytidine treatment: Splice variant diversity and frequency of exon 17 skipping correlates with the level of hMLHI promoter methylation suggesting a link between promoter methylation and mRNA splicing.

Rooibos tea flavonoids increase mineral content in human osteoblast-like cells

Some cross-sectional and prospective studies have demonstrated a positive correlation between habitual tea consumption and bone mineral density in post-menopausal women. Rooibos tea contains no caffeine and is a rich source of flavonoids such as rutin, orientin, hyperoside and luteolin. These flavonoids have similar structures to estradiol, and therefore may act as estrogen mimics to promote favourable outcomes in bone. The overall objective of this research was to identify flavonoids that could enhance mineral content in human osteoblast Saos2 cells. Mineral was quantified by alizarin red staining and characterized by quantifying alkaline phosphatase (ALP) activity, cell mitochondria activity and toxicity, in addition to changes in regulatory markers of osteoblastic activity. Rutin (≥50μM), hyperoside (≥5.0μM), orientin (0.1μM-1.0μM, 15μM-100μM) and luteolin (5.0μM) enhanced mineral content. This was in part due to elevated ALP and mitochondrial activity, and lower toxicity, pro-inflammatory cytokines, and Wnt inhibitors.

Investigation of the Biological Effects of Rosemary (Rosmarinus Officinalis L.) Extract in Human Lung Cancer Cells

Cancer cells display enhanced growth rates and a resistance to apoptosis. Lung cancer accounts for the most cancer related deaths and non-small cell lung cancer (NSCLC) represents an aggressive form of lung cancer, accounting for almost 80% of all lung cancer cases. The phytochemical rosemary extract (RE) has been reported to have anticancer effects in vitro and in vivo however, limited evidence exists regarding the effects of RE and its polyphenolic constituents carnosic acid (CA) and rosmarinic acid (RA) in lung cancer. The present study shows RE, CA and RA inhibit lung cancer cell proliferation and survival in various NSCLC cell lines and that CA and RA interact synergistically to inhibit cell proliferation. Moreover RE, CA and RA are capable of altering activation and/or expression of Akt, ERK and AMPK, signaling molecules which regulate cell proliferation and survival. RE shows potential as an anticancer agent and should be further investigated.
