“Word up” is a catch phrase that denotes agreement or enthusiasm about what another has said. A question central to this thesis was whether study participants thought that Algonquin College should endeavour to be a sustainability leader. Online and clipboard surveys, involving on- and off-campus participants, compiled new ideas of how Algonquin could educate for sustainability. These ideas formed a needs analysis that, combined with a review of trends in North American colleges’ education for sustainability, fed into program design recommendations. The program design phase of the research involved participants in an assessment of the survey results and the development of program recommendations for academic development at Algonquin College. Off-campus participants suggested new types of experiential learning involving community partners and encouraged the college to educate for careers related to sustainable food and renewable energy. On-campus participants were concerned foremost with the infusion of sustainable principles across all college curricula.

<p>  </p> <p>Individual differences in cognitive effort-based decision-making can reveal the variety of decision strategies used in action valuations. For example, factors such as how challenging an action is or how much reward can be gained are often considered when weighing how valuable an action is. Experiment 1 considers task preferences offered at different demand levels (i.e., the degree of challenge) to determine whether decision-making strategies are related primarily to 1) demand levels, 2) individual capability, or 3) task components. Results suggest that participants’ decisions were primarily driven by task options rather than their performance. Experiment 2 then compares task preferences in different incentive-related conditions. While the majority of decisions were in the predicted direction (favoring lower demand levels and higher monetary amounts), there were individual differences that suggested valuations of both task options as well as incentive conditions. The results of these experiments suggest individuals use various decision strategies involving factors that may have been overlooked in past research. These findings challenge the assumption that task preferences are primarily related to how challenging an action is and instead suggest that preferences may be highly susceptible to experimental design factors as well as factors intrinsic to the individual.</p>

Indiana University-Purdue University Indianapolis (IUPUI) / This thesis project aims to address the following question: How do women who were planning a vaginal birth with limited medical intervention experience an unplanned c-section? Specifically, this research project involved: completing in-depth interviews with 15 women who planned a vaginal birth with limited medical intervention but instead experienced an unplanned c-section between six months and two years ago; discovering and describing the nature of the birth the mothers originally envisioned for their child; exploring the women’s experiences with, and feelings about, the birth itself and how it might differ from what they envisioned; developing a better understanding of how these experiences and feelings affected the women during the first two years following the birth; describing any challenges they faced and how, if at all, they managed such challenges; and identifying strategies that could be used to improve the experience of women recovering from an unplanned c-section who envisioned a vaginal birth with limited medical intervention.

Thesis (MPhil)--Stellenbosch University, 2001. / ENGLISH ABSTRACT: It is widely accepted that the Internet has become a valuable resource for social scientists, not just for the purpose of information exchange; via e-mail, discussion groups and electronic journals, but also as a medium for data collection. Its global nature gives a researcher access to a vast range of individuals located around the world. It also opens up access to difficult to hitherto penetrate study areas, such as sensitive research on deviant behaviour. Further, it is claimed that considerable savings to both research budgets and time frames are made possible with the new technology. It is not surprising, therefore, that a substantial body of research, employing the Internet as the primary means of data collection, already exists. This raises a number of questions as to how the Internet fares as a research tool. Are there any important methodological issues that this new approach raises? Do the traditional research methods suffice? Or are adaptations to existing methods necessary when difficulties are encountered? Does such changes affect the more fundamental question of the research design? These questions are considered in this thesis. To answer them, I consider two different types of empirical research designs. The first,' survey research, is a quantitative, numerical design that traditionally has a high level of control. I consider in detail issues of sampling, including non-response, and questionnaire design. The second design examined, ethnographic research, is qualitative, textual and generally has a low level of researcher control. I address the methods used in cyber ethnography and then discuss the considerable ethical concerns that feature in such research. I conclude that, on the whole, the existing methods can be transferred to Internet research. Indeed, some of the problems faced in traditional research are also considerations in Internet studies and can be overcome by employing similar techniques, such as using incentives to reduce non-response rates. However, a number of new problems emerge, such as the lack of paralinguistic cues, which require adaptations to the existing methods in order to produce results that can be considered valid and reliable. However, I also argue that these necessary adaptations to the methods do not affect the underlying principles found in the research design. / AFRIKAANSE OPSOMMING: Dit word algemeen aanvaar dat die Internet In waardevolle hulpmiddel is vir sosiaalwetenskaplikes; nie net vir die uitruil van inligting deur middel van e-pos, besprekingsforums en elektroniese joernale nie, maar ook as In instrument om inligting te versamel. Die globale aard van die internet gee die navorser toegang to In wye spektrum individue internasionaal. Dit verleen ook toegang tot moeilike navorsingsareas, soos sensitiewe navorsing oor afwykende gedrag. Verder word beweer dat dit aansienlike besparings moontlik kan maak vir beide die navorsingsbegroting en tydraamwerk. Dit is dus nie verbasend dat In substansiële hoeveelheid van navorsing, wat die Internet as die primêre bron van dataversameling gebruik, reeds bestaan nie. Dit laat verskeie vrae ontstaan oor hoe die Internet vaar as In navorsingshulpmiddel. Is daar enige belangrike metodologiese kwessies wat hierdie nuwe metode aanraak? Is die tradisionele metodes voldoende? Of moet daar veranderinge aan die huidige metodes aangebring word wanneer probleme ontstaan? Sal hierdie veranderinge die fundamentele aspekte van navorsingsontwerp beïnvloed? Die vrae saloorweeg word in hierdie tesis. Ek gebruik twee empiriese navorsingsontwerpe om die vrae te beantwoord. Die eerste, steekproefnavorsing, is In kwantitatiewe ontwerp wat tradisioneel In hoë vlak van beheer toon. Ek ondersoek in detail kwessies van steekproewe, insluitend geen respons en vraelysontwerp. Die tweede ontwerp wat ondersoek word, etnografiese navorsing, is kwalitatief, tekstueel en toon in die algemeen In lae vlak van navorser beheer. Ek ondersoek die metodes wat gebruik word in kuberetnografie en bespreek dan die etiese vraagstukke wat hierdie navorsing kenmerk. Ek kom tot die gevolgtrekking dat oor die algemeen die huidige metodes toegepas kan word op Internetnavorsing. Inderdaad kan van die probleme wat ondervind word in tradisionele navorsing ook ondervind word in Internet studies en ook hier kan dit oorkom word deur die gebruik van soortgelyke tegnieke, soos om aansporingsbonusse om geen responskoerse te verminder, hoewel daar nuwe probleme opduik, soos die gebrek aan para-taalkundige wenke. Dit noodsaak veranderinge aan die huidige metodes om resultate te lewer wat geldig en betroubaar is. Ek redeneer egter ook dat hierdie nodige veranderinge aan die metodes nie onderliggende beginsels van navorsingsontwerp verander nie.

Waste management systems are created based on a careful balance of interrelated factors, a variety of players, and diverse political, social, and economic landscapes. The purpose of this study is to identify the impacts to waste management caused by limited supply or increased cost of energy. A case study was created based on the Alberta Capital Region using literature review, surveys and interviews to identify how energy is used throughout the various phases of waste management, from collection through to disposal and diversion, and what the factors are that affect the organization and infrastructure selected for the waste management system. The results of this study conclude that there are economic, social, environmental, political, and decision-making impacts related to an energy crisis. In particular, it was concluded that an energy crisis will cause social and economic stresses that will result in organizational and infrastructure changes to waste management.

Protected heritage area management is challenged by conflicting priorities perpetuated by the real and perceived dichotomy between cultural and natural resource management, their practitioners, their disciplines, and their values. Current guidelines promote integrating cultural and natural resource management to ensure holistic management of all values within a protected heritage area. This paper uses the management of the Cave and Basin National Historic Site to illustrate challenges in protecting both historic and natural resources. A qualitative inductive study included analysis of interview and focus group data for the site and similar protected heritage areas. The gap between integrative policies and the tendency for uni-disciplinary approaches to the practice of managing protected heritage areas is investigated. Five barriers to integration, such as lack of awareness, and five methods for progress, including facilitated inclusion, are examined. The author proposes collaborative, sustainable, values-based practices for the successful integration of cultural and natural resource management.

This descriptive, phenomenological case study presents the perspectives of small-scale coffee producers in Guatemala regarding cooperative membership, sustainable coffee certification programs and the role of ANACAFE. The viewpoints of two producer cooperatives are described based on participant observation, semi-structured interviews and focus groups. Through content analysis the transcribed data were categorized and summarized, and emergent themes are discussed. Advantages to cooperative membership include access to finances, information, cost sharing and expanding direct-trade relationships. Challenges identified are securing finances and attracting new membership. Certification programs may be desirable, but access to information regarding program types is limited. Participants feel that standards do not reflect cultural differences, and the producers question who actually receives the advertised price premiums. The use of best-practices incorporating the social, environmental and economic principles of certification programs is preferred. ANACAFE is a source of technical information and funding but resource access is selective and limited.

This study explored the extent to which using online communication tools helped NAIT (the Northern Alberta Institute of Technology) denturist students on third-year practica maintain laboratory and clinical standards of treatment. The inquiry was framed by the Community of Inquiry (CoI) framework, and was conducted from a collaborative constructivist approach with quantitative data used to enhance and support a mainly qualitative design. Results showed that all elements of a CoI were present in the online environment and that participants voluntarily used WebCT communications tools for academic and social interaction. Standards of treatment on practical projects completed by the study group were no different than those of cohorts that did not use communications tools. Modifications to instructional practices made comparison of standards achieved on patient cases unfeasible. Study results informed immediate changes made to the online practicum site, and suggestions for long-term pedagogical changes to denturist practica were made.

Indiana University-Purdue University Indianapolis (IUPUI) / Ovarian cancer (OC) is a lethal disease due to metastasis and chemoresistance. Our laboratory previously reported that tissue transglutaminase (TG2) is overexpressed in OC and enhances OC peritoneal metastasis. TG2 is a multifunctional protein which catalyzes Ca2+-dependent cross-linking of proteins. The purpose of this study was to explore the mechanism by which TG2 is upregulated in OC and its role in OC progression. We demonstrated that transforming growth factor (TGF)-β1 is secreted in the OC milieu and regulates the expression and function of TG2 primarily through the canonical Smad signaling pathway. Increased TG2 expression level correlates with a mesenchymal phenotype of OC cells, suggesting that TGF-β1 induced TG2 promotes epithelial-to-mesenchymal transition (EMT). TG2 induces EMT by negatively regulating E-cadherin expression. TG2 modulates E-cadherin transcriptional suppressor Zeb1 expression by activating NF-κB complex, which leads to increased cell invasiveness in vitro and tumor metastasis in vivo. The N-terminal fibronectin (FN) binding domain of TG2 (tTG 1-140), lacking both enzymatic and GTPase function, induced EMT in OC cells, suggesting the interaction with FN involved in EMT induction. A TGF-β receptor kinase inhibitor, SD-208, blocked TGF-β1 induced TG2 upregulation and EMT in vitro and tumor dissemination in vivo, which confirms the link between TGF-β1 and TG2 in EMT and tumor metastasis. TG2 expression was correlated with the number and size of self-renewing spheroids, the percentage of CD44+CD117+ ovarian cancer stem cells (CSCs) and with the expression level of stem cell specific transcriptional factors Nanog, Oct3/4, and Sox2. These data suggest that TG2 is an important player in the homeostasis of ovarian CSCs, which are critical for OC peritoneal metastasis and chemoresistance. TG2 expression was also increased in CSCs isolated from human ovarian tumors, confirming the implication of TG2 in CSCs homeostasis. Further, we demonstrated that TG2 protects OC cells from cisplatin-induced apoptosis by regulating NF-κB activity. We proposed a model whereby TGF-β-inducible TG2 modulates EMT, metastasis, CSC homeostasis and chemoresistance in OC. These findings contribute to a better understanding of the mechanisms of OC metastasis modulated by TG2.

Mini-dissertation submitted in partial compliance with the requirements for the Master's Degree in Technology: Homoeopathy, Durban University of Technology, 2009. / Anecdotal evidence suggests that students perceive the research component of the Master’s Degree in Technology: Homoeopathy (M.Tech: Homoeopathy) qualification at Durban University of Technology (DUT) in a negative light, and as an unnecessary obstacle to the qualification and the practice of homoeopathy (Naude, 2008). One of the reasons for this negative perception is that in terms of the Homoeopathic programme, the only exit point is upon completion of the Master’s Degree. Although relevant status is awarded upon completion of N. Dip: Homoeopathy after the third year of study and B. Tech: Homoeopathy after the fourth year of study, no actual certificates/qualifications are awarded or issued nor can the student register/practice as a Homoeopath (Durban University of Technology, 2009). The Homoeopathic profession in South Africa is unique as there are very few professional qualifications which prescribe an obligatory Master’s level qualification in order to register and practice the respective profession. Due to the M.Tech: Homoeopathy being the only exit point in the Homoeopathy programme, every registered student must complete a Master’s dissertation in order to qualify and ultimately practice Homoeopathy in South Africa, this often results in students conducting research for the wrong reasons, without the genuine academic desire to do so or the maturity and skills required (Naude, 2008). According to the Education Department of South Africa (2007), the primary purposes of a Master’s Degree are to educate and train researchers who can contribute to the development of knowledge at an advanced level, or prepare graduates for advanced and specialised professional employment. A Master’s Degree must have a significant research component. iv The Education Department of South Africa (2007), states that a Master’s Degree may be earned in either of two ways: (1) by completing a single advanced research project, culminating in the production and acceptance of a thesis or dissertation, or (2) by successfully completing a course work programme requiring a high level of theoretical engagement and intellectual independence and a research project, culminating in the acceptance of a dissertation. In the latter case, a minimum of 60 credits at level 9 must be devoted to conducting and reporting research. According to the Education Department of South Africa (2007), Master’s graduates must be able to deal with complex issues both systematically and creatively, make sound judgements using data and information at their disposal and communicate their conclusions clearly to specialist and nonspecialist audiences. Graduates must be able to demonstrate self-direction and originality in tackling and solving problems, act autonomously in planning and implementing tasks at a professional or equivalent level, and continue to advance their knowledge, understanding and skills. Methodology A non-experimental descriptive survey was conducted to determine the perceptions of DUT M.Tech: Homoeopathy graduates with regards to research as a component of the degree. A self-administered questionnaire was distributed and 50 anonymous responses were obtained. Raw data was analysed using descriptive statistics and the relationships between variables tested for correlations. v Results 27% of practicing graduates felt that research had a direct benefit on their professional development. Graduates said that after completing research they felt more competent and gained more faith in their profession. 34% of graduates thought that research had a direct benefit on their personal development. Graduates felt that on the path of working towards a long term goal they had discovered that they possessed a significant amount of patience and will power. 40% of graduates agreed that research had no contribution to their personal and professional development as a Homoeopath. Although some graduates said they felt a “sense of accomplishment” upon completing research, other graduates argued that the delay in qualifying as a result of research contributed to the loss of income and valuable clinical knowledge. Conclusions and Recommendations The process of research is a multi–factorial problem. One has to look at each individual case in order to gain insight into how to best address respective problem areas in order to improve the process of research and reduce the delays in qualification. Many graduates expressed dissatisfaction at the inconsistent time factor, from conception of the research design, to awaiting both approval of the DUT 186 and finally the marking of the completed work. Some graduates felt that difficulties relating to the quality and quantity of supervision as well as poor patient/ participant compliance were the factors responsible for their delay in qualification. Many graduates reported that the previously limited Homoeopathic research budget left them compromised for scope, diversity and new ideas. vi It was recommended that future students insist on formal supervision contracts which clearly define issues such as accessibility and timeframes. It was also recommended that future students consider at least two supervisors, preferably one being an external supervisor with suitable specialist skills concerning the respective research study. Furthermore, it was recommended that future research should be designed around easily accessible target populations. The M.Tech: Homoeopathy programme is currently undergoing recurriculation; the new curriculum will be most likely implemented in 2011. A draft curriculum has been designed by academic staff of DUT and University of Johannesburg. The proposed new curriculum aims to addresse issues such as difficulties with research as well as solutions to these difficulties.
