    The author has granted permission for their work to be available to the general public.Teaching primary and secondary students can be a fulfilling career helping children learn and grow. However, teachers also experience stress, anxiety and negative emotions that make it difficult to maintain their psychological wellness. Their stress, anxiety and negative emotions come from, among other things, the pressure for students to perform on standardized tests, student misbehavior, emotional labor from showing empathy and processing the trauma of others. Up until the mid-1980's research on teacher psychological wellness focused on reducing teacher stress and anxiety. Since then, some researchers have reframed teacher psychological wellness as the fulfillment of psychological needs for relatedness (relationships with other people), competency and autonomy. This dissertation examines the results of a quantitative study to uncover the relationship between teachers' philosophies of happiness, emotions and indicators of psychological wellness defined as the fulfillment of basic psychological needs. The study involved a survey administered to Kindergarten to 12th grade teachers from one urban school district in Texas. The survey included items from a variety of psychological scales to measure the following 10 constructs: teachers' philosophies of happiness (virtue ethics, deontology, utilitarianism and physiological), emotions (anger, anxiety and satisfaction) and indicators of psychological wellness (relatedness, autonomy and competency). The study also involved structural equation modeling to determine the relationships between constructs. This structural equation modeling revealed complex relationships between constructs that in some cases conflicted with what existing theories say should be the nature of these connections. Chapters 4 and 5 of the dissertation discuss those unexpected results.Educational Leadership and Policy Studie

    1 Timothy 1:3–4 in the Memory of Irenaeus, Tertullian, Athanasius, and Chrysostom

    No full text
    In this article, I discuss reception history, its place within the history of historical critical methods, and social memory theory. I apply a reception historical lens buttressed by social memory theory to 1 Timothy 1:3–4. I show that the historical circumstances of this passage’s reception problematize using early understandings of it to reconstruct the referent behind “myths and endless genealogies”. I first show how the phrase “myths and endless genealogies” is ambiguous in the historical setting of the author. Then, I demonstrate that Irenaeus, Tertullian, Athanasius, and Chrysostom use this phrase against very different groups; however, all of these authors use 1 Timothy 1:4 for a (perceived) problem against their present group

    Scientific research is a competitive business – in order to secure funding, promotion and tenure researchers must demonstrate their work has impact in their field. To maximise impact researchers undertake high priority research, aim to get results first, and publish in the highest impact journals. The Internet now presents a new opportunity to the scholarly author seeking higher impact: s/he can now make their work instantly accessible on the Web through author self-archiving. This growing body of open access literature (coupled with new publishing models that make journals available for-free to the reader) maximises research impact by maximising the number of people who can read it, and making it available sooner. Open access also provides a new opportunity for bibliometric research. This thesis describes the relatively recent phenomenon of open access to research literature, tools that were built to collect and analyse that literature, and the results of analyses of the effect of open access and its effect on author behaviour. It shows that articles self-archived by authors receive between 50-250% more citations, that rapid pre-printing on the Web has dramatically reduced the peak citation rate from over a year to virtually instant and how citation-impact – now widely used for evaluation – can be expanded to include a new web metric of download impact

    Mixed-domain performance model of the piezoelectric traveling-wave motor and the development of a two-sided device

    Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Aeronautics and Astronautics, 2002.Page 226 blank.Includes bibliographical references (p. 221-225).This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.In recognition of the growing consideration of piezoelectric traveling-wave motors as suitable replacements for small-scale electromagnetic motors, the present work addresses two parallel objectives: (1) to develop an advanced modeling approach for the accurate prediction of steady-state performance of piezoelectric traveling-wave motors, and (2) to improve upon the typical piezoelectric traveling-wave motor configuration by investigating the novel implementation of two-sided operation. Firstly, a performance model of the piezoelectric traveling-wave motor has been developed that accounts for loss at the material level through the integration of complex material constants. In effect, all model parameters can be attributed to physically relevant properties, and, as demonstrated by the success of several experimental correlation studies, motor performance can be predicted independently of the measured characteristics of an existing device. Other key features of the model include a dynamic rotor model, a hysteretic stick-slip friction contact model, and generalization to accommodate non-ideal traveling-wave excitation. Critical to the cohesion of the model, a mixed-domain formulation combines the ease and accuracy of deriving the nonlinear contact forces in the time domain and the efficiency of equilibrating the modal forces in the frequency domain.(cont.) Secondly, a two-sided motor configuration has been developed that is theoretically capable of doubling the torque and power output of the typical configuration with little or no increase in size or mass. Controlled experimental testing has been performed concurrently on essentially identical one-sided and two-sided prototypes, and the results verify a dramatic performance improvement due to the implementation of two-sided operation.by Timothy Scott Glenn.Ph.D

    Motion and mobility in the realist novels of Philip K Dick

    No full text
    This essay explores the ways that ideas of motion and mobility support readings of Philip K Dick's early novels that take full account of the changing geographical context. They are set during a period of rapid suburban expansion, the building of the interstate and the spread of automobility through car ownership, and their characters frequently exist in a state between continuity through conformity and the potential for change. The open ended forms of the novels reflect a world around Dick that was still under construction, and where alternative realities can be glimpsed between incomplete materialities

    Modelling visitor experience: a case study from World Heritage Sites, Thailand.

    No full text
    The subject of this Ph.D. Thesis is Modelling Visitor Experience: A Case Study from World Heritage Sites, Thailand. The research is conducted in three historical parks in Thailand by using an inductive approach of Grounded Theory. This aims to propose a model of visitor experience of heritage. It focuses on experience consumption related to what, why and how visitors consume the heritage experience when they interact with the cultural heritage. The construction of experience, factors affecting experience consumption and patterns of experience consumption are explored in this thesis. It provides theoretical and methodological contribution to the knowledge in both tourism and management fields. The opportunity to collect data for this study stems from the three historical sites in Thailand by which grounded theory approach allows for a wider variety of data collection methods. The research had been conducted in the historical sites for over six months during October 2003 March 2004. The results presented in this thesis are based on a survey of 60 cases of participant observations with ethnographic interview and 180 cases of observation with visitors visiting the historical sites, and 48 unstructured and semi-structured interviews with visitors who visited those sites. The results are also based on a number of supplementary data such as travel journals, visitor books, and interpreted photographs written and taken by visitors who visited to the sites. Survey instruments for this study consist of interview and observation guides that were developed accordingly to emergent concepts during the field survey. The contributions comprise four major themes. Firstly, the development of the 'Visitor Heritage Experience Model' based on multiple sources of data conceptualised by a systematic analysis process. The model provides the insight of visitors' subjective interactions with the heritage when they were engaged in a consumption of experience. This study reveals the multi-dimensional nature of visitor experience which expands what has been reported in the literatures. It also explains the complex attributes of visitors' on-site experience in terms of process and components of experience construction. Secondly, the emergent of 'Interactive Experience Process' as a core of the proposed model, acknowledges the dynamic nature of on-site experience through a multi-phase experience process and multiplicity of visitors' experience consumption practices. Rather than acknowledging the tourist typology, this study explores the extent to which the elements of experience hold in different contexts and types of consumption experiences. The emergent theory can be used as a substantive theory to apply for other case studies involving visitors' experience of place. Thirdly, the findings of this study have significant implications for designing principles and practices of an effective and sustainable visitor management in cultural heritage sites. The development of the, Visitor Experience Management Framework' discusses the creative use of the heritage and visitor empowerment to provide interactive experience of heritage to visitors. It suggests the consideration of a paradigm shift and crucial elements of visitor experience management especially in sensitive cultural heritage sites. Finally, this study provides several conceptual and methodological research perspectives through the use of 'Grounded Theory Approach'. The applications of the grounded theory's systematic analysis process can be adopted by future consumer and management research

    DNA fusion gene vaccination mobilizes effective anti-leukemic cytotoxic T lymphocytes from a tolerized repertoire

    The majority of known human tumor-associated antigens derive from non-mutated self proteins. T cell tolerance, essential to prevent autoimmunity, must therefore be cautiously circumvented to generate cytotoxic T cell responses against these targets. Our strategy uses DNA fusion vaccines to activate high levels of peptide-specific CTL. Key foreign sequences from tetanus toxin activate tolerance-breaking CD4+ T cell help. Candidate MHC class Ibinding tumor peptide sequences are fused to the C terminus for optimal processing and presentation. To model performance against a leukemia-associated antigen in a tolerized setting, we constructed a fusion vaccine encoding an immunodominant CTL epitopederived from Friend murine leukemia virus gag protein (FMuLVgag) and vaccinated tolerant FMuLVgag-transgenic (gag-Tg) mice. Vaccination with the construct induced epitopespecificIFN-c-producing CD8+ T cells in normal and gag-Tg mice. The frequency and avidity of activated cells were reduced in gag-Tg mice, and no autoimmune injury resulted. However, these CD8+ T cells did exhibit gag-specific cytotoxicity in vitro and in vivo. Also, epitope-specific CTL killed FBL-3 leukemia cells expressing endogenous FMuLVgag antigen and protected against leukemia challenge in vivo. These results demonstrate a simple strategy to engage anti-microbial T cell help to activate epitope-specific polyclonal CD8+ T cell responses from a residual tolerized repertoire

    547 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 2001.Lastly, the author proposed a comprehensive liquefaction analysis procedure for sandy soils to evaluate liquefaction susceptibility, liquefaction triggering, and post-triggering stability. The procedure incorporates the proposed relationships to estimate yield and liquefied strength ratio, and does not require a suite of laboratory tests or corrections for sloping ground and vertical effective stress. The procedure is verified initially using the Lower San Fernando Dam case history.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD
