2	National Identity Transnational Identification: The City and the Child as Evidence of Identification Among the Poetic Elite Hedengren, Mary L. 12 March 2010 (has links) (PDF) While poetry has historically been connected with rhetoric, few rhetoricians have studied contemporary poetry. Jeffery Walker suggests that this is because contemporary poetry, unlike classical poetry, no longer addresses all socio-economic levels of society but has become insular and self-referential (329). He criticizes that poetry no longer cuts vertically across one culture's hierarchy. I agree that poetry no longer addresses all segments of society, but I argue that this doesn't mean poetry is no longer rhetorical. Contemporary poetry now operates horizontally to unite the cultural elite of many national and ethnic groups by appealing to their identity as poetry readers. Using the identification theories of Kenneth Burke and Naomi Marin, the rhetoric in contemporary poetry becomes more apparent. As an example of how contemporary poetry creates identification among the literary elite, I examine the work of Aleš Debeljak—a former Yugoslavian Slovene poet who must define his national identity while appealing to a transnational community of poetry readers. Debeljak's poetry demonstrates the sophisticated work poetry does to create identify and identification.

3	The Feasibility of Implementing Froh’s Gratitude Curriculum with Adolescents in an Emotional Support Classroom Crawford, Candy, 0000-0003-0792-652X January 2020 (has links) This feasibility study examined if adolescents (n=14) ages 10-14 who were assigned to an emotional support classroom could learn the principles of gratitude through a teacher taught gratitude curriculum. I was interested in the following research questions: (1) Can the Froh curriculum be implemented with fidelity in an adolescent ES class? (2) When implemented with fidelity, does the curriculum result in adolescents in ES classes learning gratitude skills? (3) Does the curriculum lead to increases in gratitude and pro-social behavior as measured by independent scales? (4) How do students feel about the curriculum? The results were that the fidelity measure yield 100% and students scored an average of 78% on the lesson posttests indicating that they had a basic understanding of the content. A significant result was found using a paired samples t-test and a non-parametric Wilcoxin test for the Gratitude Questionnaire (GQ-6) p = .019, and the strengths and difficulties questionnaire (SDQ) pro-social behavior subscale score p = .002 from pre to post-testing. The Gratitude Intervention Rating Scale: Post Implementation, results showed that students felt they learned the lessons. The students felt that their teacher should use the curriculum with other students because they felt it helped them in their daily lives. Overall, the results indicated that it is feasible to use Froh’s (2014) gratitude curriculum with students assigned to an emotional support classroom. / Educational Psychology Educational Psychology Psychology Behavioral Psychology Emotional Needs Emotional Support Emotional Support Intervention Gratitude Jeffery Froh Prosocial Behavior
4	A MEMS based valveless micropump for biomedical applications Van der Merwe, Schalk Willem 03 1900 (has links) Thesis (MScEng (Mechanical and Mechatronic Engineering))--University of Stellenbosch, 2010. / ENGLISH ABSTRACT: The valveless micropump holds great potential for the biomedical community in applications such as drug delivery systems, blood glucose monitoring and many others. It is also a critical component in many a lab-on-a-chip device, which in turn promises to improve our treatment and diagnosis capabilities for diseases such as diabetes, tuberculosis, and HIV/AIDS. The valveless micropump has attracted attention from researchers on the grounds of its simple design, easy manufacturability and sensitive fluid handling characteristics, which are all important in biomedical applications. The pump consists of a pump chamber with a diffuser and nozzle on opposing sides of the pump chamber. The flow into the diffuser and nozzle is induced by an oscillating piezoelectric disc located on top of the pump chamber. The nozzle and diffuser rectify the flow in one direction, due to different pressure loss coefficients. The design process however is complex. In this study, we investigate the characteristics of a diffuser / nozzle based micropump using detailed computational fluid dynamic (CFD) analyses. Significant parameters are derived using the Buckingham-Pi theorem. In part based on this, the respective shapes of the diffuser and of the nozzle of the micropump are selected for numerical investigation. Hence the influence of the selected parameters on the flow rate of the micropump is studied using three-dimensional transient CFD analyses. Velocity profiles from the CFD simulations are also compared to the Jeffery-Hamel solution for flow in a wedge shaped channel. Significant similarities exist between the data and the predicted Jeffery-Hamel velocity profiles near the exit of the diffuser. Three different diffuser geometries were simulated at three frequencies. The flow rate and direction of flow are shown to be highly sensitive to inlet and outlet diffuser shapes, with the absolute flow rate varying by as much as 200% for the geometrical perturbations studied. Entrance losses at both the diffuser inlet and nozzle inlet appear to dominate the flow resistance at extremely laminar flow conditions with the average Reynolds number of Reave ≈ 500. / AFRIKAANSE OPSOMMING: Die kleplosemikropomp hou groot potensiaal in vir die biomediese gemeenskap in toepassings soos medisyne dosering sisteme, bloed glukose monitering en baie ander. Dit is ook ’n kritiese komponent in “lab-on-chip” sisteme, wat beloof om die behandeling en diagnose van siektes soos suikersiekte, tuberkulose enMIV/VIGS te verbeter. Die kleplose mikropomp het tot dusver die aandag van navorsers geniet as gevolg van sy eenvoudige ontwerp, maklike vervaardiging en sensitiewe vloeistof hantering. Hierdie kenmerke is krities inmenige biomediese toepassings. Die pomp bestaan uit ’n pompkamer met ’n diffusor en ’n mondstuk aan teenoorstaande kante van die pompkamer. Vloei in die diffusor en mondstuk in word geinduseer deur ’n ossillerende piëso-elektiese skyf wat bo-op die pompkamer geleë is. Weens verskillende druk verlies koëffisinëte van die diffusor en diemondstuk word die vloei in een rigting gerig. Die ontwerp-proses is egter kompleks. In hierdie studie word die eienskappe van die diffusor /mondstuk ondersoek deur gebruik temaak van gedetailleerde numeriese vloei-dinamiese analises. Belangrike parameters word afgelei deur gebruik te maak van die Buckingham-Pi teorema. Gedeeltelik gebaseer hierop word die onderskeidelike vorms van die diffusor en die mondstuk van die mikropomp geselekteer vir numeriese ondersoek. Gevlolglik word die invloed van die geselekteerde parameters op die vloei tempo van diemikropomp ondersoek deur gebruik temaak van drie-dimensionele tyd afhanklike numeriese vloei-dinamiese analises. Snelheids profiele van hierdie simulasiesword vergelykmet die Jeffrey-Hamel oplossing vir die vloei in ’n wigvormige kanaal. Daar is oorwegende ooreenkomstighede tussen hierdie data en die voorspelde Jeffrey-Hamel snelheids profiele veral by die uitgang van die diffusor. Drie verskillende diffusor vorms is by drie frekwensies gesimuleer. Daar is bewys dat die vloei tempo en vloeirigting baie sensitief is vir inlaat- en uitlaat diffusor vorms en dat die absolute vloei tempo kan varieermet soveel as 200%vir die geometriese versteuringswat ondersoek is.

5	Numerical simulation of an inertial spheroidal particle in Stokes flow / Numerisk simulering av en trög sfäroidisk partikel i Stokesflöde Bagge, Joar January 2015 (has links) Particle suspensions occur in many situations in nature and industry. In this master’s thesis, the motion of a single rigid spheroidal particle immersed in Stokes flow is studied numerically using a boundary integral method and a new specialized quadrature method known as quadrature by expansion (QBX). This method allows the spheroid to be massless or inertial, and placed in any kind of underlying Stokesian flow. A parameter study of the QBX method is presented, together with validation cases for spheroids in linear shear flow and quadratic flow. The QBX method is able to compute the force and torque on the spheroid as well as the resulting rigid body motion with small errors in a short time, typically less than one second per time step on a regular desktop computer. Novel results are presented for the motion of an inertial spheroid in quadratic flow, where in contrast to linear shear flow the shear rate is not constant. It is found that particle inertia induces a translational drift towards regions in the fluid with higher shear rate. / Partikelsuspensioner förekommer i många sammanhang i naturen och industrin. I denna masteruppsats studeras rörelsen hos en enstaka stel sfäroidisk partikel i Stokesflöde numeriskt med hjälp av en randintegralmetod och en ny specialiserad kvadraturmetod som kallas quadrature by expansion (QBX). Metoden fungerar för masslösa eller tröga sfäroider, som kan placeras i ett godtyckligt underliggande Stokesflöde. En parameterstudie av QBX-metoden presenteras, tillsammans med valideringsfall för sfäroider i linjärt skjuvflöde och kvadratiskt flöde. QBX-metoden kan beräkna kraften och momentet på sfäroiden samt den resulterande stelkroppsrörelsen med små fel på kort tid, typiskt mindre än en sekund per tidssteg på en vanlig persondator. Nya resultat presenteras för rörelsen hos en trög sfäroid i kvadratiskt flöde, där skjuvningen till skillnad från linjärt skjuvflöde inte är konstant. Det visar sig att partikeltröghet medför en drift i sidled mot områden i fluiden med högre skjuvning.

6	A Total Cost Approach to Supply Chain Risk Modeling Saunders, Brian J. 08 December 2011 (has links) The modern supply chain is long, complex, interconnected and global, and plays a fundamental role in business competitiveness. These conditions, along with various supply chain management trends in recent years have increased risks in supply chains which threaten supply chain performance. Greater impact, especially on cost, from an increased threat of supply disruptions is one area of particular concern. Companies today are struggling to find effective means to manage this increased risk and avoid adverse financial impacts. An approach to managing supply disruption risk in supply chains based on the minimization of the total cost of ownership (TCO) of the supply chain is explored in this thesis. Insights are provided into an appropriate view of supply chain risk and a general four step risk management process to guide the design and evaluation of a new risk management tool based on such an approach. A prototype of the new total cost-based, modeling and simulation tool was created in partnership with ProModel Corporation and a government contractor that requested to remain anonymous. A preliminary assessment of the effectiveness of this tool in minimizing TCO and providing an interface useable by non-modelers is provided. This study also reviews and compares a sample set of current supply chain risk management methods and tools and compares them with the new tool for relevance in aiding users in managing supply disruption risk. Based on literature findings and preliminary feedback from pilot contextual demonstrations of the tool, the total cost approach to risk modeling appears promising, although the execution needs to be improved with further enhancements made to the prototype tool. In this preliminary study and evaluation, sufficient evidence is not available to determine that the new prototype tool is any more effective than other currently available risk management tools to provide necessary information to make supply chain risk management decisions that minimize TCO of a supply chain. Suggestions for further development of the tool, especially for improvement of the total cost approach, are provided as well as a preliminary evaluation procedure and survey instruments for a more robust evaluation of the new tool.

7	From the "rising tide" to solidarity: disrupting dominant crisis discourses in dementia social policy in neoliberal times MacLeod, Suzanne 26 March 2014 (has links) As a social worker practising in long-term residential care for people living with dementia, I am alarmed by discourses in the media and health policy that construct persons living with dementia and their health care needs as a threatening “rising tide” or crisis. I am particularly concerned about the material effects such dominant discourses, and the values they uphold, might have on the collective provision of care and support for our elderly citizens in the present neoliberal economic and political context of health care. To better understand how dominant discourses about dementia work at this time when Canada’s population is aging and the number of persons living with dementia is anticipated to increase, I have rooted my thesis in poststructural methodology. My research method is a discourse analysis, which draws on Foucault’s archaeological and genealogical concepts, to examine two contemporary health policy documents related to dementia care – one national and one provincial. I also incorporate some poetic representation – or found poetry – to write up my findings. While deconstructing and disrupting taken for granted dominant crisis discourses on dementia in health policy, my research also makes space for alternative constructions to support discursive and health policy possibilities in solidarity with persons living with dementia so that they may thrive. / Graduate / 0452 / 0680 / 0351 / macsuz@shaw.ca social determinants of health social exclusion crisis discourse Alzheimer's Alzheimer Society of Canada Suzanne MacLeod Susan Strega Donna Jeffery poststructural poststructuralism admission to long-term care funding for long-term care acute care aging demographic BC Psychogeriatric Association biomedical British Columbia Canada Health Act collective social responsibility competition corporate profit corporatization deresponsibilization elder friendly elderly citizens family caregivers Foucault found poetry genealogy of power knowledge incompetent Ministry of Health moral economics pharmaceutical bed blocker stigmatized tsunami absent-person action plan aging population alternative discourse apocalyptic demography appropriate archaeology archaeology of knowledge archaeological British Columbia burden Canada caregiver charity charitable collective collective car community community care condition of possibility conditions of possibility corporate counter-discourse dementia dementia care dementia policy dementia social policy dependent depoliticize discourse discourse analysis disruptive discourse economic burden economics economy elder emergency epidemic exclusion fear-monger Foucauldian found poem genealogy genealogical health authority health care health care staff health care system health policy document healthy lifestyle home and community care homogenization homogenize hospital imaginaries imaginary incapable individual responsibility individualism knowledge long-term care material effect materiality of discourse media moral panic national strategy neoliberal neoliberalism neoliberal rationality not prepared object objectification other person-centered people living with dementia person living with dementia persons living with dementia person with dementia poem poetic representation poetry policy policies political politics power power knowledge power relations private privatize privatization productivity of dominant discourse public health care residential care resistance responsibility responsibilization rising tide safety net shift costs to caregivers responsibility social policy imaginary social well-being social work social worker solidarity specialized stakeholder state stigma subject matter expert taxpayer threat unprepared unproductive voluntary volunteer wait time wave social policy
