description: In this work we present the results of investigations of photoluminescence with doped quantum wells in the near infrared range at a temperature of 4.2K to 300 K. We use two nanostructures. The first nanostructure has GaAs / AlGaAs quantum wells doped with a donor impurity of silicon. Another nanostructure has GaAs / AlGaAs quantum wells doped with a silicon donor impurity and an acceptor beryllium impurity. The impurities of silicon and beryllium are doped in equal amounts. In spectra in the near infrared range, peaks associated with electron transitions of the main electron subband to the main subband of holes and observed as well as from the ground state of the donor to the main subband of holes . Based on this information, the energy of the transitions is determined in the THz range.

title: Particle Dynamics and Resistivity Characteristics in Bifurcated Current Sheets
Creators: name: Andriyas, Tushar
Publisher: name: Utah State University
Year: 2013

description: Charged particle chaos and its collective effects in different magnetic geometries are investigated in a sequence of various numerical experiments. The fields generated by the particles as a result of interaction with the background electric and magnetic fields is not accounted for in the simulation. An X-line is first used to describe the geometry of the magnetotail prior to magnetic reconnection and a study of the behavior of charged particles is done from a microscopic viewpoint. Another important geometry in the magnetotail prior to substorm onset is Bifurcated Current Sheet. The same analysis is done for this configuration. The existence of at least one positive Lyapunov exponent shows that the motion of the particles is chaotic. By using statistical mechanics, the macroscopic properties of this chaotic motion are studied. Due to particles being charged, an electric field (perpendicular to the magnetic field in weak magnetic field region) accelerates the particles on average. Finite average velocity in the direction of electric field gives rise to an effective resistivity even in a collisionless regime such as solar corona and the magnetotail. Starting from initial velocities that are chosen randomly from a uniform distribution, the evolution of these distributions tends to a Maxwellian by the end of the simulation that is somewhat analogous to collisions in a Lorentz gas model. The effective resistivity due to such collisions is estimated. Ohmic heating is found to occur as a result of such an effective resistivity. Such collisions due to collective particle effects are essentially a different mechanism from classical collision notion. These experiments are done for two types of ions found in the plasma sheet prior to substorm onset, viz., protons and oxygen ions. Observational evidence of oxygen ions in the central plasma sheet, which flow out along open field lines from the ionosphere, were also simulated in the same manner. Oxygen ions have been found to influence the bifurcation of the current sheet and are also important in reconnection and other nonohmic instabilities, such as Kelvin Helmholtz instability, due to their mass. It is found that acceleration in X-line scales with the mass of ion species and the resistivity remains constant for different electric field strengths. In a Bifurcated Current Sheet, the acceleration scales with the square of mass of ion species and the resistivity scales with the electric field. Also, the overall resistivity values found in a Bifurcated Current Sheet are an order of magnitude lower than that found in an X-line.

description: During the COVID-19 pandemic, people accessed nature for a sense of support from the isolation of lockdown restrictions in the UK. For many this involved accessing local greenspace and private gardens to benefit mental wellbeing. However, for those within low-income areas nature was accessed to a lesser extent due to a lack of public and private greenspace within these areas. One type of nature-based activity which has been found to benefit individuals from low-income areas is allotment gardening. Within these areas allotments have been found to be sites of positive community change, benefitting wellbeing through allowing for escape, social cohesion with likeminded people and empowerment. As allotments are grounded within the community, they often allow for residents to access nature whilst not leading to the gentrification of the local area. Therefore, allotment gardening may provide a solution to the problem of greening low-income areas without causing the displacement of residents. This thesis explores the experience of allotment gardening for individuals living within low-income areas of Nottingham. Using a combination of ethnography, Interpretative Phenomenological Analysis (IPA) and Experiential Reflexive Thematic Analysis (ERTA) alongside photo elicitation, surveys and field notes, this thesis provides a rich account of the experiences of two groups of participants who use the allotment site; new tenants from low-income areas of Nottingham and members of staff and volunteers who work on the site. The analysis of data revealed the following themes. In chapter six, “It’s always going to be something which I associate myself with”: Connection to Self, “It’s not just your allotment”: Connection with Others and “I find the allotment a safe place”: A Space of Sanctuary were identified. In chapter seven, “Commonness amongst all the other people”: Connection with Allotment Culture, “This one’s mine”: Empowerment through Ownership and “you just lose yourself”: Tuning into Nature were highlighted. Finally, chapter eight outlined the themes “It attaches to so many families”: Community Cohesion, “A real sense of freedom”: A Place for Personal Growth and “There’s no hard energies”: A Refuge for Mental Health. The findings demonstrate the importance of allotment gardening within low-income areas for individual identity, social cohesion, empowerment and mental health. The research also highlights the efficacy of combining ethnography with IPA and ERTA to provide a rich and rounded approach to exploring individual experience. Finally, this thesis has implications for government and local councils by highlighting the importance of allotments for tacking the issue of greening low-income areas.
Spectral responses in granular compaction

Year: 2009
Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: The slow compaction of a gently tapped granular packing is reminiscent of the low-temperature dynamics of structural and spin glasses. Here, I probe the dynamical spectrum of granular compaction by measuring a complex (frequency-dependent) volumetric susceptibility $\tildeχ_v$. While the packing density $ρ$ displays glass-like slow relaxations (aging) and history-dependence (memory) at low tapping amplitudes, the susceptibility $\tildeχ_v$ displays very weak aging effects, and its spectrum shows no sign of a rapidly growing timescale. These features place $\tildeχ_v$ in sharp contrast to its dielectric and magnetic counterparts in structural and spin glasses; instead, $\tildeχ_v$ bears close similarities to the complex specific heat of spin glasses. This, I suggest, indicates the glass-like dynamics in granular compaction are governed by statistically rare relaxation processes that become increasingly separated in timescale from the typical relaxations of the system. Finally, I examine the effect of finite system size on the spectrum of compaction dynamics. Starting from the ansatz that low frequency processes correspond to large scale particle rearrangements, I suggest the observed finite size effects are consistent with the suppression of large-scale collective rearrangements in small systems.

title: A Numerical Algorithm For Simulating Two Species Plasma
Creators: name: Datwyler, Richard F.
Publisher: name: Utah State University
Year: 2013

description: An algorithm for modeling two species plasmas, which evolves the number density, flow velocity, and temperature equations coupled to Maxwell's electric and magnetic field equations, is discussed. Charge separation effects and the displacement current are retained. Mathematical derivations of normal modes in cold and hot plasmas, as represented by dispersion relations resulting from a linear analysis of the two fluid equations, are presented. In addition, numerical theory in relation to the ideas of geometry, temporal and spatial discretization, linearization of the fluid equations, and an expansion using finite elements is given. Numerical results generated by this algorithm compare favorably to analytical results and other published work. Specifically, we present numerical results, which agree with electrostatics, plasma oscillations at zero pressure, finite temperature acoustic waves, electromagnetic waves, whistler waves, and magnetohydrodynamics (MHD) waves, as well as a Fourier analysis showing fidelity to multiple dispersion relations in a single simulation. Final consideration is given to two species plasma stability calculations with a focus on the force balance of the initial conditions for a resistive MHD tearing mode benchmark and a static minimum energy plasma state.
title: Using QUAL2Kw as a Decision Support Tool: Considerations for Data Collection, Calibration, and Numeric Nutrient Criteria
Creators: name: Hobson, Andrew J.
Publisher: name: Utah State University
Year: 2013

description: The in-stream water quality model, QUAL2Kw, can provide guidance in watershed management decisions by linking changes in nutrient loads to responses in water quality. This model is particularly useful for determining wasteload allocations, aiding in total maximum daily load analyses, and developing numeric nutrient criteria. Unfortunately, states struggle to balance the data collection and modeling requirements to accomplish many of these water quality management tasks due to limited resources. This commonly results in routine data collection and monitoring efforts that do not satisfy the data requirements for modeling. To address this disconnect, this study presents a data collection and parameter calibration methodology suited to meet general QUAL2Kw modeling requirements. Then, with the goal of identifying a range of numeric nitrogen and phosphorus criteria, this general data collection and modeling strategy was applied to sites throughout Utah. To help automate and test scenarios targeted at tracking effects of loading and response combinations, a nutrient criteria tool was also developed to interface with these QUAL2Kw models. By implementing the tool on these models, input concentrations of ammonium (NH4+) ranging from 10 to 101 µg/L and inorganic phosphorus (PO4-) ranging from 1 to 14 µg/L were found to exceed thresholds of bottom algae, gross primary productivity, and ecosystem respiration. Conversely, NH4+ concentrations above 3,500 µg/L and PO4- above 490 µg/L exceeded dissolved oxygen thresholds of 5-6 mg/L in some applications. Some limitations of using mechanistic models in this manner were identified, including model capabilities (e.g., steady-state versus dynamic), inclusion of appropriate processes, uncertainty in calibrated parameters, and site-specific conditions. Although many problems will require more complex modeling efforts with significantly larger data collection efforts, this approach provides an initial framework that aids in the judicial use of resources to aid in watershed management decisions.

description: Massive, eclipsing, double-lined, spectroscopic binaries are not common but are necessary to understand the evolution of massive stars as they are the only direct way to determine stellar masses. They are also the progenitors of energetic phenomena such as X-ray binaries and gamma-ray bursts. We present a photometric and spectroscopic analysis of the candidate binary system Cyg OB2-B17 to show that it is indeed a massive evolved binary. We utilise V band and white-light photometry to obtain a light curve and period of the system, and spectra at different resolutions to calculate preliminary orbital parameters and spectral classes for the components. Our results suggest that B17 is an eclipsing, double-lined, spectroscopic binary with a period of 4.0217+/-0.0004 days, with two massive evolved components with preliminary classifications of O7 and O9 supergiants. The radial velocity and light curves are consistent with a massive binary containing components with similar luminosities, and in turn with the preliminary spectral types and age of the association.

description: In the Standard Model, a group of heavy fermions, e.g. top quarks, can collectively strongly affect the Higgs field and create relatively long-lived bound states. If there exist new generations of fermions with masses beyond 1 TeV, strong binding of several of them can make them lighter than even a single heavy fermion. Using the mean field approximation we find multi-fermion states with masses M ~ 5 v N^{1/2} ~ 1.2 N^{1/2} TeV, with N=2,3... being the total number of heavy fermions bound together, and v=246 GeV the Higgs VEV. The experimental search for multi-fermions within the range of energies 2-3 Tev would either discover them, or suggest absence of new Standard Model fermions with larger masses. Possible implications related to multi-top states and baryonic asymmetry of the Universe are discussed.
title: Spanish-speaking Parents' Negotiation of Language and Culture with their Children's Schools
Creators: name: Bickmore, Ronda L.
Publisher: name: Utah State University
Year: 2013

description: Latinos are now the largest public school minority population in the U.S. Because of a shift in the states, cities, and counties where Latinos are choosing to live, many schools that did not previously serve substantial numbers of Latinos are doing so now. Additionally, many of the Latinos in these new settlement areas are recent immigrants who speak little or no English. This qualitative study examined how immigrant Latino parents who speak little or no English supported their children in the English-speaking school system of the U.S. It specifically examined how 12 Spanish-speaking parents negotiated language and culture with their children's school in a new settlement area in the state of Utah. From the interviews I conducted with the Latino parents and school staff members, along with school observations and the collection of other data such as forms and notices, I examined how the parents negotiated language and culture with the school. I then analyzed the themes that emerged from this collection of data using a theoretical framework consisting of postcolonial theory, social and cultural capital, and the concept of social discourses. Major themes that emerged included the concern the parents had for their children's education, the parents' limited participation in the school discourse, children serving as language brokers, the maintenance and growth of their children's heritage language, the hegemony of the English language, and issues involving social and cultural capital, linking capital, and racism. Recommendations include assuring availability of interpreters, increasing bridging and linking capital, supporting children's heritage language, and being culturally sensitive and proactive to reduce racism. Hopefully, this research will add to the literature that will help educators better serve the growing Latino school population.

title: Evaluation of the TGF-ß Inhibitor RepSox on the Expression of Pluripotency Pathways in Murine and Bovine Cells
Creators: name: Larsen, Davin M.
Publisher: name: Utah State University
Year: 2013

description: Embryonic stem cells are pluripotent cells isolated from morula stage embryos or the inner cell mass of blastocyst stage embryos. They are capable of differentiating into tissues of all three primary germ layers. In recent years pluripotent cell lines have been created from somatic cell types using various methods, the primary method being viral transduction of exogenous Oct4, Sox2, Klf4, and c-Myc or Oct4, Sox2, Nanog, and Lin28 transgene constructs. The resulting cell lines are termed induced pluripotency stem cells, and are similar to embryonic stem cells in many ways. However, these cell lines are not acceptable for clinical applications due to the use of both modified viral vectors and insertion of exogenous transgenes in their production. Recently the small molecule RepSox, a TGF-ß pathway inhibitor, was used to replace Sox2 during cellular reprogramming of murine embryonic fibroblasts. We evaluated the effects of RepSox on expression of pathways related to pluripotency in murine embryonic fibroblast, murine embryonic stem, and bovine embryonic fibroblast cells. Each cell type was treated with RepSox for 72 hours and subjected to standard qPCR for gene expression analysis. PCR arrays specific to stem cell pathways were used to initially evaluate the effects of RepSox on candidate genes. A subset of genes was then selected for further analysis based on these initial results. We report that RepSox inhibition of the TGF-ß pathway in murine embryonic fibroblasts results in significant upregulation of components of the Wnt, Notch, and Hedgehog signaling pathways, all of which have been linked to stem cell maintenance. In addition, we observed significant upregulation of genes associated with embryonic, mesenchymal, stem cell, and neural cell lineages, indicating that RepSox may be useful in direct reprogramming of murine cells to other somatic cell types. RepSox treatment of murine embryonic stem cells did not result in consistent upregulation of Wnt, Notch, or Hedgehog pathway components, but did result in upregulation of Sox2 and Klf4 expression. Lastly, RepSox treatment of bovine embryonic fibroblasts did not result in the same effects as seen in murine fibroblasts, indicating a need for further analysis to determine the effects of RepSox on bovine cells.

Publisher: name: Utah State University
Year: 2013

description: This work presents an enhancement to the classification tree algorithm which forms the basis for Random Forests. Differently from the classical tree-based methods that focus on one variable at a time to separate the observations, the new algorithm performs the search for the best split in two-dimensional space using a linear combination of variables. Besides the classification, the method can be used to determine variables interaction and perform feature extraction. Theoretical investigations and numerical simulations were used to analyze the properties and performance of the new approach. Comparison with other popular classification methods was performed using simulated and real data examples. The algorithm was implemented as an extension package for the statistical computing environment R and is available for free download under the GNU General Public License.

description: Context as the dynamic information describing the situation of items and users and affecting the users decision process is essential to be used by recommender systems in mobile commerce to guarantee the quality of recommendation. This paper proposes a novel multidimensional approach for context aware recommendation in mobile commerce. The approach represents users, items, context information and the relationship between them in a multidimensional space. It then determines the usage patterns of each user under different contextual situations and creates a new 2 dimensional recommendation space and does the final recommendation in that space. This paper also represents an evaluation process by implementing the proposed approach in a restaurant food recommendation system considering day, time, weather and companion as the contextual information and comparing the approach with the traditional 2 dimensional one.

description: The effects of the final state interaction in slow proton production in semi inclusive deep inelastic scattering processes off nuclei, A(e,e'p)X, are investigated in details within the spectator and target fragmentation mechanisms; in the former mechanism, the hard interaction on a nucleon of a correlated pair leads, by recoil, to the emission of the partner nucleon, whereas in the latter mechanism proton is produced when the diquark, which is formed right after the visrtual photon-quark interaction, captures a quark from the vacuum. Unlike previous papers on the subject, particular attention is paid on the effects of the final state interaction of the hadronizing quark with the nuclear medium within an approach based upon an effective time-dependent cross section which combines the soft and hard parts of hadronization dynamics in terms of the string model and perturbative QCD, respectively. It is shown that the final state interaction of the hadronizing quark with the medium plays a relevant role both in deuteron and complex nuclei; nonetheless, kinematical regions where final state interaction effects are minimized can experimentally be selected, which would allow one to investigate the structure functions of nucleons embedded in the nuclear medium; likewise, regions where the interaction of the struck hadronizing quark with the nuclear medium is maximized can be found, which would make it possible to study non perturbative hadronization mechanisms.

description: We propose a mechanism of thermalization of nucleons in relativistic nucleus-nucleus collisions. Our model belongs, to a certain degree, to the transport ones; we consider the evolution of the system, but we parametrize this development by the number of collisions of every particle in the system rather than by the time variable. We based on the assumption that the nucleon momentum transfer after several nucleon-nucleon (-hadron) collisions becomes a random quantity driven by a proper distribution.

title: Statistical Algorithms for Optimal Experimental Design with Correlated Observations
Creators: name: Li, Chang
Publisher: name: Utah State University
Year: 2013

description: This research is in three parts with different although related objectives. The first part developed an efficient, modified simulated annealing algorithm to solve the D-optimal (determinant maximization) design problem for 2-way polynomial regression with correlated observations. Much of the previous work in D-optimal design for regression models with correlated errors focused on polynomial models with a single predictor variable, in large part because of the intractability of an analytic solution. In this research, we present an improved simulated annealing algorithm, providing practical approaches to specifications of the annealing cooling parameters, thresholds and search neighborhoods for the perturbation scheme, which finds approximate D-optimal designs for 2-way polynomial regression for a variety of specific correlation structures with a given correlation coefficient. Results in each correlated-errors case are compared with the best design selected from the class of designs that are known to be D-optimal in the uncorrelated case: annealing results had generally higher D-efficiency than the best comparison design, especially when the correlation parameter was well away from 0. The second research objective, using Balanced Incomplete Block Designs (BIBDs), wasto construct weakly universal optimal block designs for the nearest neighbor correlation structure and multiple block sizes, for the hub correlation structure with any block size, and for circulant correlation with odd block size. We also constructed approximately weakly universal optimal block designs for the block-structured correlation. Lastly, we developed an improved Particle Swarm Optimization(PSO) algorithm with time varying parameters, and solved D-optimal design for linear regression with it. Then based on that improved algorithm, we combined the non-linear regression problem and decision making, and developed a nested PSO algorithm that finds (nearly) optimal experimental designs with each of the pessimistic criterion, index of optimism criterion, and regret criterion for the Michaelis-Menten model and logistic regression model.

description: We study a nonlinear system of partial differential equations in which a complex field (the Higgs field) evolves according to a nonlinear Schroedinger equation, coupled to an electromagnetic field whose time evolution is determined by a Chern-Simons term in the action. In two space dimensions, the Chern-Simons dynamics is a Galileo invariant evolution for A, which is an interesting alternative to the Lorentz invariant Maxwell evolution, and is finding increasing numbers of applications in two dimensional condensed matter field theory. The system we study, introduced by Manton, is a special case (for constant external magnetic field, and a point interaction) of the effective field theory of Zhang, Hansson and Kivelson arising in studies of the fractional quantum Hall effect. From the mathematical perspective the system is a natural gauge invariant generalization of the nonlinear Schroedinger equation, which is also Galileo invariant and admits a self-dual structure with a resulting large space of topological solitons (the moduli space of self-dual Ginzburg-Landau vortices). We prove a theorem describing the adiabatic approximation of this system by a Hamiltonian system on the moduli space. The approximation holds for values of the Higgs self-coupling constant close to the self-dual (Bogomolny) value of 1. The viability of the approximation scheme depends upon the fact that self-dual vortices form a symplectic submanifold of the phase space (modulo gauge invariance). The theorem provides a rigorous description of slow vortex dynamics in the near self-dual limit.

description: In real life, media information has time attributes either implicitly or explicitly known as temporal data. This paper investigates the usefulness of applying Bayesian classification to an interval encoded temporal database with prioritized items. The proposed method performs temporal mining by encoding the database with weighted items which prioritizes the items according to their importance from the user perspective. Naive Bayesian classification helps in making the resulting temporal rules more effective. The proposed priority based temporal mining (PBTM) method added with classification aids in solving problems in a well informed and systematic manner. The experimental results are obtained from the complaints database of the telecommunications system, which shows the feasibility of this method of classification based temporal mining.

Emotional responses of young children to hospital and surgery : a comparative study of procedures and facilities in the Vancouver General Hospital, 1953-58
Creators: name: Holloway, Shirley Kathleen
Publisher: name: University of British Columbia
Year: 2012

description: The present study constitutes an attempt to observe and measure the emotional responses of young children to hospitalization and surgery. There has been much inquiry and comment from psychiatric and medical sources which suggests that this experience may be seriously traumatic for some children, and social workers are rightly concerned about the possibilities of modifying the frightening aspects of hospital routines on the basis of their knowledge of children's emotional needs. A sample group of children (20) referred for tonsillectomy and adenoidectomy by the Ear, Nose, and Throat Clinic of the Vancouver General Hospital was studied. The mother of each child was interviewed, three months after the hospitalization of her child, on the basis of a comprehensive questionnaire designed to determine the child's behaviour before and after surgery, including his usual reactions to punishment and the nature of the punishment. Relevant references by medical and social workers were studied, including the Albany Research Project which was a notable example of team research by a paediatrician, an anaesthetist, a psychiatrist, and a social worker, to establish patterns of child's reactions to the same operation in the Albany Hospital. Similar methods of assessing adjustment by measuring neuropathic traits before and after the experience were used. In the present study, special emphasis was laid upon ascertaining the nature of the mother-child relationship and the degree of anxiety around separation. Some follow-up was also incorporated. The same wards were observed five years later and differences in setting, policy, and procedures were noted and evaluated in terms of the earlier findings. It was found that ten of the twenty children suffered a severe emotional setback as a result of their illness and hospitalization. It was also observed that many of the children confused surgery with punishment and many had unrealistic ideas about the purpose of hospitalization. It is suggested that poor preparation contributed to this confusion, and that unimaginative methods of applying standard hospital procedures to small patients often confirmed fears and anxiety. Because the child's reaction to hospitalization is essentially based on the quality of his relationship with his mother, it is concluded that surgery should be postponed, if possible, until after five years of age; or, where postponement is impossible, mothers should be able to accompany young children to hospital. Some modifications in hospital routines applicable to children in hospital are suggested. The later observation of Vancouver General Hospital showed great changes in setting and policy, especially in regard to visiting, but found the two major procedures of admitting to hospital and preparation for anaesthesia and surgery virtually unchanged.
Determination of screened Coulomb repulsion energies in organic molecular crystals: A real space approach

description: We present a general method for determining screened Coulomb parameters in molecular assemblies, in particular organic molecular crystals. This allows us to calculate the interaction parameters used in a generalized Hubbard model description of correlated organic materials. In such a model only the electrons in levels close to the Fermi level are included explicitly, while the effect of all other electrons is included as a renormalization of the model parameters. For the Coulomb integrals this renormalization is mainly due to screening. For molecular materials we can split the screening into intra- and inter-molecular screening. Here we demonstrate how the inter-molecular screening can be calculated by modeling the molecules by distributed point-polarizabilities and solving the resulting self-consistent electrostatic screening problem in real space. For the example of the quasi one-dimensional molecular metal TTF-TCNQ we demonstrate that the method gives remarkably accurate results.

description: This research introduces a pioneering framework for the synthesis and generation of ontologies in the critical domain of microeconomics. Leveraging hybrid learning paradigms, the model employs LSTM classifiers, TF-IDF, and Structural Topic Modelling to classify a dataset of microeconomic documents. Integration with knowledge repositories like YAGO, RDF generation, and metadata enhancement further enriches the model's auxiliary knowledge. The convolutional neural networks (CNN) play a pivotal role in classifying and refining knowledge. Semantics-oriented reasoning is achieved through standard measures like NPMI, Associate PMI, Second-Order co-occurrence PMI, and Jaccard Similarity, with intermediate optimisation using particle swarm optimisation (PSO). This proposed framework establishes the first ontology for microeconomics, boasting a precision of 95.09%, an impressive F-measure of 96.957%, and a minimal FDR value of 0.05. It stands out as the leading model for ontology generation in the field.

Creators: name: Ryan, Bernadene J.
Publisher: name: Utah State University

description: Transformation events can be a change in a person's work, a change in philosophy, a sudden insight, or a break in a relationship. According to David Hufford and Marilyn Motz, narrating these experiences are ways in which people perform, construct, and communicate belief systems. The narrators within the context of this thesis experience their transformation through a career transformation. The narrators rediscover their initial passion and transform that desire into actions that results in a shift of career. Sometimes seen as inexplicable, nevertheless the narrators provide analysis and reflection on the influences that led to their change. Some of the actions or thoughts that the narrators incorporate in their stories demonstrate not only the progression of events but also the alterations narrators experience in their worldviews. The context in which these changes occur is essential to interpreting and understanding the experience. Narrative components are filtered through an interpretive process that includes personal meaning, contrast with social norms and cultural beliefs and the impact on the receiver to enable narrators to justify their experience. It is the reflection on these experiences through which people gain insight and establish relevance to events that seem sometimes beyond their control. Stories from pop culture to ordinary citizens who change their lives daily demonstrate the pervasiveness of the transformational effect of states of crisis through which people journey. People's lives are turned upside-down through these experiences which place the narrator out of their normal element. There are two levels to these story types: external and internal transformation. At a superficial level there is the journey to change careers but at another level there is a relationship to opening up cultural expectations or acting generatively, as role-models. Narrators are effecting change through their positive attitudes and acceptance of the trials they encounter during their transitions. Narrators discuss specific actions that create transformative life changes or philosophical shifts. My investigation studies how individuals are involved in transitional events in which they experience a disengagement from a previous life, spending some time in liminal space where they transition or regenerate into a new place in society. Part of my approach to this subject matter used theories introduced by Victor Turner (pilgrimages) and by Arnold Van Gennep (rites of passage). Regina Holloman proposes that rites of passage can occur not just as physical/material transformation but can occur psychically as well. Some of the narrative patterns that narrators use to construct these tales are identified within the context of folk belief and folklore scholarship.
