Höyryturbiinin ulosvirtauskanaviston kokeellinen tutkimus pienoismallilla

Diplomityössä tutkittiin höyryturbiinin ulosvirtauskanavistojen kokeellisia tutkimusmenetelmiä ja suoritettiin käytännön mittauksia Fortum Oyj:n Loviisan ydinvoimalaitoksen höyryturbiinien huuvan pienoismallilla. Kirjallisuusselvityksen perusteella todettiin, että pienoismallitutkimuksella on ollut keskeinen asema ulosvirtauskanavistojen suunnittelussa. Kokeellisten menetelmien perusongelmana on höyryturbiinin ulosvirtausolosuhteiden jäljitteleminen. Käytetyt mittausmenetelmät perustuvat pääosin tavanomaisiin paine- ja nopeusmittauksiin. Lisäainepartikkeleihin ja laser-valaisuun perustuva PIV (particle image velocimetry) todettiin lupaavaksi menetelmäksi ulosvirtauskanavistojen tutkimuksen saralla. Työn käytännön osuudessa tehtiin mittauksia mittasuhteessa 1:8 rakennetulle höyryturbiinin huuvan pienoismallille. Mittauksilla tutkittiin virtausta mallin sisääntulo- ja ulostulotasoissa. Lisäksi mitattiin staattisen paineen jakauma huuvan sisällä. Kokonaispainetta mittaava kiel-putki todettiin käytännölliseksi työkaluksi huuvan virtauskentän tutkimuksessa. Tuloksista käy hyvin ilmi huuvan ulostuloon syntyvien pyörteiden muodostuminen ja ulostulon epätasainen nopeusjakauma. Staattinen paine huuvan sisällä havaittiin epätasaisesti jakautuneeksi. Ulostulotason ja staattisen paineen mittauksilla saadut tulokset sopivat hyvin yhteen kirjallisuudesta löytyvien tutkimustulosten kanssa ja tukevat Loviisan ulosvirtauskanavistosta aiemmin tehtyjä CFD-simulointeja.

Heidegger and Blumenberg on modernity

The debate surrounding the way in which Heidegger and Blumenberg understand the modern age is an opportunity to discuss two different approaches to history. On one hand, from Heidegger's perspective, history should be understood as starting from how Western thought related to Being, which, in metaphysical thinking, took the form of the forgetfulness of Being. Thus, the modern age represents the last stage in the process of forgetfulness of Being, which announces the moment of the rethinking of the relationship with Being by appealing to the authentic disclosure of Being. On the other hand, Blumenberg understands history as the result of the reoccupation process, which means replacing old theories with other new ones. Thus, to the historical approach it is not important to identify epochs as periods of time between two events, but to think about the discontinuities occurring throughout history. Starting from here, the modern age will be thought of not as an expression of the radicalization of the forgetfulness of Being, but as a response to the crises of medieval conceptions. For the same reason, the interpretation of history as a history of the forgetfulness of Being is considered by Blumenberg to subordinate history to an absolute principle, without taking into account its protagonists' needs and necessities.

An examination of existential faith in the writtings of Søren Kierkegaard

This thesis takes seriously the proposition that existentialism is a lived philosophy. While Descartes' proof for the existence of God initially sparked my interest in philosophy, the insights of existentialism have allowed me to appropriate philosophy as a way of life. I apply the insights of Kierkegaard's writings to my spiritual and philosophy development. Philosophy is personal, and Kierkegaard's writings deal with the development of the person in his aesthetic, ethical and religious dimensions. Philosophy is a struggle, and this thesis, reveals the existential struggle of the individual in despair. The thesis argues that authentic faith actually entails faith. The existential believer has this faith whereas the religious believer does not. The subjectively reflective existential believer recognizes that a leap of faith is needed; anything else, is just historical, speculative knowledge. The existential believer or, the Knight of Faith, realizes that a leap of faith is needed to become open in inwardness to receive the condition to understand the paradoxes that faith presents. I will present Kierkegaard's "Analogy of a House" which is in essence, the backbone of his philosophy. I will discuss the challenge of moving from one floor to the next. More specifically, I will discuss the anxiety that is felt in the very moment of the transition from the first floor to the second floor. I will outline eight paradoxes that must me resolved in order for the individual to continue on his journey to the top floor of the house. I will argue that Kierkegaard's example of Abraham as a Knight of Faith is incorrect, that Abraham was in fact not a Knight of Faith. I will also argue that we should find our own exemplars in our own lives by looking for Knight of Faith traits in people we know and then trying to emulate those people. I will also discuss Unamuno's "paradoxical faith" and argue that this kind of faith is a strong alternative to those who find that Kierkegaard's existential faith is not a possibility.

The essence of a tacit intersection : a heuristic inquiry into nature-based leisure and personal transformation

There are a considerable number of programs and agencies that count on the existence of a unique relationship between nature and human development. In addition, there are significant bodies of literature dedicated to understanding developmentally focused nature-based experiences. This research project was designed to flirther the understanding of this phenomenon. Consequently, the purpose of this research endeavour was to discover the essence ofthe intersection ofpersonal transformation and nature-based leisure, culminating in a rich and detailed account of this otherwise tacit phenomenon. As such, this research built on the assumption of this beneficial intersection of nature and personal transformation and contributes to the understanding ofhow this context is supporting or generating of selfactualization and positive development. Heuristic methods were employed because heuristics is concerned with the quality and essence of an experience, not causal relationships (Moustakas, 1990). Heuristic inquiry begins with the primary researcher and her personal experience and knowledge of the phenomenon. This study also involved four other coresearchers who had also experienced this phenomenon intensely. Co-researchers were found through purposeful and snowball sampling. Rich narrative descriptions of their experiences were gathered through in-depth, semi-structured interviews, and artifact elicitation was employed as a means to get at co-researchers' tacit knowledge. Each coresearcher was interviewed twice (the first interview focused on personal transformation, the second on nature) for approximately four and a half hours in total. Transcripts were read repeatedly to discern patterns that emerged from the study of the narratives and were coded accordingly. Individual narratives were consolidated to create a composite narrative of the experience. Finally, a creative synthesis was developed to represent the essence of this tacit experience. In conclusion the essence of the intersection of nature-based leisure and personal transformation was found to lie in the convergence of the lived experience of authenticity. The physical environment of nature was perceived and experienced to be a space and context of authenticity, leisure experiences were experienced as an engagement of authenticity, and individuals themselves encountered a true or authentic self that emanated from within. The implications of these findings are many, offering suggestions, considerations and implications from reconsidered approaches to environmental education to support for selfdirected human development.

A narrative journey of teacher reflexivity and authenticity in technological environments /

This qualitative narrative inquiry was driven by my desire to further explore my personal discovery that my utilization of educational technologies in teaching and learning environments seemed to heighten a sense of creativity, which in turn increased reflective practice and authenticity in my teaching. A narrative inquiry approach was used as it offered the opportunity to uncover the deeper meanings of authenticity and reflection as participants' personal experiences were coconstructed and reconstructed in relationship with me and in relationship to a social milieu. To gain further insight into this potential phenomenon, I engaged in 2 conversational interviews with 2 other teachers from an Ontario College in a large urban centre who have utilized educational technologies in their teaching and learning communities and I maintained a research journal, constructed during the interview process, to record my own emerging narrative accounts, reflections, insights and further questions. The field texts consisted of transcriptions of the interviews and my reflective journal. Research texts were developed as field texts were listened to multiple times and texts were examined for meanings and themes. The educational technologies that both women focused on in the interview were digital video of children as they play, learn and develop and the use of an audible teacher voice in online courses. The invitation given to students to explore and discover meaning in videos of children as they watched them with the teacher seemed to be a catalyst for authenticity and a sense of synergy in the classroom. The power of the audible teacher voice came through as an essential component in online learning environments to offer students a sense of humanness and connection with the teacher. Relationships in both online and face to face classrooms emerged as a necessary and central component to all teaching and learning communities. The theme of paradox also emerged as participants recognized that educational technologies can be used in ways that enhance creativity, authenticity, reflection and relationships or in ways that hinder these qualities in the teaching and learning community. Knowledge of the common experiences of college educators who utilize educational technologies, specifically digital video of children to educate early childhood educators, might give meaning and insight to inform the practice of other teachers who seek authentic, reflexive practice in the classroom and in on line environments.

A study on the role of the parent in educational decision making from the perspective of parents and teachers

ADeweyan (1916) democratic theoty ofeducation called for the participation ofall citizens in deliberating important educational issues to improve overall student learning. Thus, the move to include parents in educational decision making can be considered to be rooted in democratic principles. To gain greater insight into the issue ofparent involvement in educational decision making, one elementary school was studied and a triangulization method was employed in an attempt to clarify the important issues surrolUlding the move to include parents in the governance ofschools. The three methods to gain information included surveys, interviews, and documentation ofsignificant school events and related work. All ofthe parents and teachers ofthe school were surveyed, 10 parents and 6teachers were interviewed, and related school events were recorded. The survey design was modeled on the Parent Involvement Questionnaire (PIQ) created and reported on by Chavkin and Williams (1987). The results ofthe surveys were used as a guide for the interview questions. An interview outline was developed based on Seidman's (1991) open-ended approach and Patton's (1980) standardized open-ended interview style in which parents and teachers were asked about their experiences and opinions on anmnber ofparent involvement issues. Parents and teachers in this school indicated agreater interest in becoming more aware ofeducational issues such as school budget and school discipline policies. Although the parents indicated agreater interest in school matters and the teachers indicated awillingness to include parents in school matters, both the parents and teachers in this study perceived the role ofthe parent as advisory, not decision making. It was concluded that to ensure ameaningful and functional role for parellts as tlleir p811icipatioll ill educational matters evolves, SCllools must have a clear vision ofthe primary goal ofall schools, namely, to foster and nourish democratic citizens for ademocratic society (Glickman, 1993). Furthennore, intentional practices such as Purkey's (ad) 5-P Relay approach, based on a democratic theory and practice of education, will have to be employed in order to give parents an authentic voice in educational matters and provide an avenue for parents to acquire the necessary skills and lmowledge needed to do so. As schools, school boards, and the Ministry ofEducation implement parent involvement guidelines and policies, developmental needs ofeach school need to be considered to ensure the employment ofdemocratic practices not authoritarian mandates. Parent interest and involvement, at whatever level, should be an important element in the overall move to make schools part ofthe democratic society they were meant to be.

An examination of Simone de Beauvoir's theme of situated embodiment

Abstract This thesis is an examination of Simone de Beauvoir's theme of situated embodiment. The aim of the thesis is to demonstrate that the theme of situated embodiment was a concern of Beauvoir's since early childhood and that it was this interest which was the impetus for Beauvoir's later philosophical notion of authentic embodiment. Through the examination of Beauvoir's autobiographies it becomes evident that Beauvoir consistently demonstrates an early awareness that one's situation will be expressed through one's body. This idea is also present in Beauvoir's novels. In the novels it is shown that many of the characters are struggling within authentic embodiment. Beauvoir also fictionalizes many of her own experiences in the novels. These novels are used as concrete examples of Beauvoir's philosophy. Through Beauvoir's philosophical works it becomes evident that authentic embodiment will include the notions of freedom, ambiguity, and reciprocity. All are crucial when trying to live an authentic existence. Beauvoir's philosophy also focuses on marginalized groups who are in the position ofthe Other. One of the marginalized groups studied are women, and this thesis investigates Beauvoir's understanding of why woman is in the position of the Other. This thesis also addresses two feminist criticisms of Beauvoir's study on women. These criticisms are argued against in an effort to defend the notion ofauthentic situated embodiment as delineated in the first three chapters. Overall it is established that Beauvoir's early experiences allowed for her to form the philosophical idea of situated embodiment that lies at the core of her philosophy.

International volunteers at a Costa Rican organic farm : sheepish volunteers, proud tourists and unwitting developers

This thesis analyzes the practices and experiences of two groups of Canadian volunteers who visited the organic fanning and "alternative development" project ofFinca la Flor (FLF) in central Costa Rica. Using both participant observation and in-depth interviews with volunteers and other people involved with FLF, I examine volunteers' understandings of their involvement with the fann. I argue that three discursive fonnations are instrumental in shaping this particular volunteering encounter. Specifically, interpretation of these Canadian volunteers' experiences inspires the argument that the emerging practice of international volunteering (or voluntourism) exists at the intersection of discourses of development, volunteering and tourism, all of which both reflect and maintain problematic North-South relationships. The analysis shows that in spite ofFLF's construction as an (alternative / sustainable) international-development project, and in spite of volunteers' initial conceptualization of their trip as "volunteering," volunteers tend to act and describe their time at FLF in ways that look more like tourism than like volunteer labor or international development. Likewise, although FLF claims to principally be focused on alternative development, and merely to open up this authentic development space to volunteers for their participation, the organization in both practice and discourse seems primarily to construct a tourist experience and cater to the needs of foreigners as tourists. Discourses of development and volunteering do infonn the practices offann personnel and volunteers at FLF, but they become subordinated to the more dominant discourse of tourism as the volunteers' and fann management's ideals of development and volunteering capitulate to become focused on satisfying volunteers' (perceived or "real") touristic desires. The FLF participants I studied may have entered the encounter as volunteers, but they departed the site having been tourists.

Manufacturing 'authenticity' : a case study of the Niagara wine cluster

In this thesis, I use "Fabricating Authenticity," a model developed in the Production of Culture Perspective, to explore the evolving criteria for judging what constitute "real" and authentic Niagara wines, along with the naturalization of these criteria, as the Canadian Niagara wine cluster has come under increasing stress from globalization. Authenticity has been identified as a hallmark of contemporary marketing and important to cultural industries, which can use it for creating meaningful differentiation; making it a renewable resource for securing consumers, increasing market value; and for relationships with key brokers. This is important as free trade and international treaties are making traditional protective barriers, like trade tariffs and markups, obsolete and as governments increasingly allocate industry support via promotion and marketing policies that are directly linked to objectives of city and regional development, which in turn carry real implications for what gets to be judged authentic and inauthentic local culture. This research uses a mixed methods research strategy, drawing upon ethnographic observation, marketing materials, newspaper reports, and secondary data to provide insight into the processes and conflicts over efforts to fabricate authenticity, comparing the periods before and after the passage of NAFT A to the present period. The Niagara wine cluster is a good case in point because it has little natural advantage nor was there a tradition of quality table wine making to facilitate the naturalization of authenticity. Geographic industrial clusters have been found particularly competitive in the global economy and the exploratory case study contributes to our understanding of the dynamic of '1abricating authenticity," building on various theoretical propositions to attempt to derive explanations of how global processes affect strategies to create "authenticity," how these strategies affect cultural homogeneity and heterogeneity at the local level, and how the concept of "cluster" contributes to the process of managing authenticity.

Closing the summer learning gap for vulnerable junior kindergarten students

Under current academic calendars across North America, summer vacation creates a significant gap in the learning cycle. I t has been argued that this gap actually decreases student achievement levels over the course of the summer. In a synthesis of 39 studies Cooper, Nye, Charlton, Lindsay, & Greathouse (1996) indicated that summer learning loss equaled at least one month of instruction as measured by grade level equivalents on standardized test scores whereby children's test scores were at least one month lower when they returned to school in the fall than scores were when students left in the summer. Specifically, Cooper et aI., (1996) found that the summer learning loss phenomena may be particularly troublesome for less advantaged children including those with speech and language delays, children at-risk for reading disabilities, children from lower socio-economic backgrounds, and children learning English as a second language. In general, research illustrated clearly that the summer learning gap can be particularly problematic for vulnerable children and furthermore, that literacy skills may be the area of achievement that is most affected. A foundational pillar to this research project is including primary caregivers as authentic partners in a summer literacy program designed to support their children's literacy needs. This pillar led the research team to use the Learning Begins at Home: A Research-Based Family Literacy Program Curriculum designed by Antoinette Doyle, Kathleen Hipfner-Boucher, and Janette Pelletier from the Ontario Institute for the Studies of Education. The LBH program is designed to be flexibly adapted to suit the needs of each individual participating family. As indicated by Timmons (2008) literacy interventions are most powerful when they include authentic family involvement. Based on this research, a requirement for participating in the summer literacy program was involvement of a child and one of their primary caregivers. The participating caregiver was integrally involved in the program, participating in workshop activities prior to and following hands-on literacy work with their child. By including primary caregivers as authentic partners, the research team encouraged a paradigmatic shift in the family whereby literacy activities become routine within their household. 5 Participants in this study were 14 children from junior kindergarten classrooms within the Niagara Catholic District School Board. As children were referred to the program, they were assessed by a trained emergent literacy specialist (from Speech Services Niagara) to identify whether they met the eligibility requirements for participation in the summer program. To be eligible to participate, children demonstrated significant literacy needs (i.e. below 25%ile on the Test of Preschool Early Literacy described below). Children with low incidence disabilities (i.e. profound sensory impairments, severe intellectual impairments, developmental disabilities, etc) were excluded as participants. The research team used a standard pre- and posttest design whereby all participating children were assessed with the Test of Preschool Early Literacy (Lonigan et aI., 2007), and a standard measure of letter names and sounds. Pretests were administered two weeks prior to the commencement of the program and the first set of posttests was administered immediately following the program. A second set of posttests was administered in December 2009 to measure the sustainability of the program. As a result of the program, all children scored statistically significantly higher on their literacy scores at the post-program assessment point immediately following the program and also at the Dec-post-program assessment point. These results in general indicated that the summer family literacy program made an immediate impact on the emergent literacy skills of participating children. All participating children demonstrated significant increases in print and phonological awareness as well as their letter sound understanding.

Hoosiers on the Hardwood: A Critical Examination of Indiana Basketball Culture and its Effect on Identity Formation

The purpose of this research was to examine the nexus at which Indiana basketball and the state’s ‘hoosier’ identity meet. More specifically, this thesis interrogates the romanticization of this sporting culture for its pedagogical role in the creation of twenty-first century ‘hoosier’ bodies. Adopting a theoretical orientation rooted in critical race theory, I argue that Indiana’s basketball culture represents a normalized / normalizing structure underneath which Otherness is reified to produce hypervisible “different” outsiders (‘non-hoosiers’), and invisible “disciplined” insiders (i.e. ‘hoosiers’). Utilizing data gleaned over a two-month period spent conducting fieldwork in the “hoosier state” (document analysis, unstructured interviewing, and participant observation), I specifically tailor my analysis to uncover people’s understanding, negotiation, and performance of this regional and national subject position. From this point of inquiry, authentic ‘hoosierness’ comes to be represented, known, practiced, and felt in relation to hierarchies of power that privilege white, hypermasculine, rural, and conservative bodies.

Beyond the Veil: A Case Study of Context, Culture, Curriculum, and Constructivism at Dubai Women's College

This case study of curriculum at Dubai Women's College (DWC) examines perceptions of international educators who designed and implemented curriculum for female Emirati higher-educational students in the UAE, and sheds light on the complex social, cultural, and religious factors affecting educational practice. Participants were faculty and supervisors, mainly foreign nationals, while students at DWC are exclusively Emirati. Theories prominent in this study are: constructivist learning theory, trans formative curriculum theory, and sociological theory. Change and empowerment theory figure prominently in this study. Findings reveal this unique group of educators understand curriculum theory as a "contextualized" construct and argue that theory and practice must be viewed through an international lens of religious, cultural, and social contexts. As well, the study explores how mandated "standards" in education-in the form of the International English Language Testing System (IEL TS) and integrated, constructivist curriculum, as taught in the Higher Diploma Year 1 program-function as dual curricular emphases in this context. The study found that tensions among these dual emphases existed and were mediated through specific strategies, including the use of authentic texts to mirror the IEL TS examination during in-class activities, and the relevance of curricular tasks.

Creating a Space for Self-Transformation: Factors of Success for Adult Literacy Learners with Specific Learning Difficulties

A significant number of adults in adult literacy programs in Ontario have specific learning difficulties. This study sought to examine the holistic factors that contributed to these learners achieving their goals. Through a case study design, the data revealed that a combination of specific learning methods and strategies, along with particular characteristics of the instructor, participant, and class, and the evidence of self-transformation all seemed to contribute to the participant's success in the program. Instructor-directed teaching and cooperative learning were the main learning methods used in the class. General learning strategies employed were the use of core curriculum and authentic documents, and using phonics, repetition, assistive resources, and using activities that appealed to various learning styles. The instructor had a history of both professional development in the area of learning disabilities as well as experience working with learners who had specific learning difficulties. There also seemed to be a goodness of fit between the participant and the instructor. Several characteristics of the participant seemed to aid in his success: his positive self-esteem, self-advocacy skills, self-determination, self-awareness, and the fact that he enjoyed learning. The size (3-5 people) and type of class (small group) also seemed to have an impact. Finally, evidence that the participant went through a self-transformation seemed to contribute to a positive learner identity. These results have implications for practice, theory, and further research in adult education.

"I'm Your Biggest Fan, I'll Follow You ... " Lady Gaga, Little Monsters and the Religious Dimension of Fandom in Pop Music

This thesis examines the religious dimension of fandom in popular music, taking as an object of reflection Lady Gaga and her fans. I combine fan studies with theories of immanence as well as Deleuze and Guattari's notion of the process of becoming, and provide a theoretical reading of the relationship between Lady Gaga and her most fervent fans, the 'little monsters.' Both fandom and religion promise a stable sense of identity and authentic community to devotees. Performing deconstructive discourse analysis on three of Lady Gaga's music videos, I demonstrate how fandom, like organized religion, can simultaneously be an emancipatory practice and a practice that seeks to deny individual subjects their agency. This thesis provides a new theoretical framework for understanding fandom, and illustrates how the purported benefits of both fandom and religion can only be gained when the figureheads of each group are symbolically destroyed by the members themselves.
