description: This thesis concerns the topic of teaching and using communication strategies (CSs) in a lower-proficiency university EFL setting in Japan. It approaches the topic from several angles, all from a teacher-as-researcher position. Its overarching goal is to explore unscripted, all-English in-class interactions among lower-proficiency learners—a group that, while it comprises the majority of English learners in the Japanese university context, remains understudied. The thesis begins with an autoethnography (Chapter 1) that explores the critical junctures that led the teacher/author toward creating a CS-integrated classroom design. Chapter 2 reviews the CS literature from a pedagogical perspective, specifically considering EFL teachers who may be interested in introducing CS training in their L2 classes. Chapter 3—a previously published paper—outlines the author’s classroom setup, which is based on principles of ‘strong task-based language teaching’ (strong TBLT). The design employs all-English role-play discussions. The task serves as a locus for spontaneous use of CSs to occur in student-student interactions. 
Chapters 4, 5, and 6 take an intimate look at the exchanges in the discussion task outlined in Chapter 3 through discourse analysis. Chapter 4 examines the “ask for help” (appeal for assistance) CS. Findings suggest that direct appeals promote clarification of misunderstandings soon after the appeal occurs. Chapter 5 explores enjoyment humorous exchanges that often occur within the discussion. Two patterns emerged: (1) witty arguments within the rules of the task, and (2) going on tangents from the main topic. Summarily, the findings suggest that even lower-proficiency learners are capable of engaging in complex forms of humor and wordplay. Chapter 6 looks further at instances of enjoyment as they relate to CS use. Two CSs stood out: paraphrase and avoidance. The implication is that avoidance CSs deserve reconsideration where the teaching of CSs is concerned. Finally, Chapter 7 suggests research agenda for further exploration of themes in each of the other chapters, particularly for the key findings, which are (1) that direct appeals for assistance to an interlocutor result in expedient resolution to lexical difficulties; (2) that humor and enjoyment in all-English interaction are possible even at lower levels of proficiency, and (3) that the use of avoidance CSs can involve humor rather than embarrassment or shame.

Combinations of coupled cluster, density functionals, and the random phase approximation for describing static and dynamic correlation, and van der Waals interactions

description: Contrary to standard coupled cluster doubles (CCD) and Brueckner doubles (BD), singlet-paired analogues of CCD and BD (denoted here as CCD0 and BD0) do not break down when static correlation is present, but neglect substantial amounts of dynamic correlation. In fact, CCD0 and BD0 do not account for any contributions from multielectron excitations involving only same-spin electrons at all. We exploit this feature to add---without introducing double counting, self-interaction, or increase in cost---the missing correlation to these methods via meta-GGA density functionals (TPSS and SCAN). Furthermore, we improve upon these CCD0+DFT blends by invoking range separation: the short- and long-range correlations absent in CCD0/BD0 are evaluated with DFT and the direct random phase approximation (dRPA), respectively. This corrects the description of long-range van der Waals forces. Comprehensive benchmarking shows that the combinations presented here are very accurate for weakly correlated systems, while also providing a reasonable description of strongly correlated problems without resorting to symmetry breaking.

description: Nitrate ion spikes in polar ice cores are contentiously used to estimate the intensity, frequency, and probability of historical solar proton events, quantities that are needed to prepare for potentially society-crippling space weather events. We use the Whole Atmosphere Community Climate Model to calculate how large an event would have to be to produce enough odd nitrogen throughout the atmosphere to be discernible as nitrate peaks at the Earth's surface. These hypothetically large events are compared with probability of occurrence estimates derived from measured events, sunspot records, and cosmogenic radionuclides archives. We conclude that the fluence and spectrum of solar proton events necessary to produce odd nitrogen enhancements equivalent to the spikes of nitrate ions in Greenland ice cores are unlikely to have occurred throughout the Holocene, confirming that nitrate ions in ice cores are not suitable proxies for historical individual solar proton events.

Nature-culture interactions: understanding the prevalence of malaria in the northern Ecuadorian Amazon
Creators: name: Polo, Patricia E.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: Malaria is an endemic disease in Ecuador with epidemic episodes. About 60% of Ecuadorians are at risk of becoming infected with the malaria parasite (falciparum and vivax). The country faces all the malaria impacts present elsewhere, including physical and mental incapacities of infected people, economic loss at the individual and country level, mortality, and resistance of vectors and parasites to insecticides and drugs. This study analyzes how the prevalence of malaria is related to colonos' (peasants) cultural practices and to land use/land cover change in the agricultural frontier of the Northern Ecuadorian Amazon, where malaria is endemic. The effects of socio-economic, demographic, and land use/land cover factors on the presence of malaria in households were studied at the farm and household level, through a binomial logistic regression model. Landscape dynamics and their impact on malaria were studied at the provincial level using Remote Sensing imagery, GIS coverages, and pattern metrics analysis. Results indicate the Ecuadorian Amazon is subject to frontier malaria, with a high incidence of malaria in the first 6-8 years of settlement, when the rate of forest clearing is greatest, and declining incidence after this period. The decline is believed to be due to geographic factors, such as the retreat of forest edges from colonos' dwelling units and the consequent decline in contact with the forest. Nevertheless, malaria remains prevalent. In sum, the fragmentation of the landscape has influenced the spatial trajectory of this disease, while colonos behavior has emerged as a primary factor in determining their likelihood of receiving anopheles mosquito bites.

Propagation of Sound in a Bend Joining Two Straight Waveguides of Rectangular Cross-Section
Creators: name: Osborne, William Chisnall
Publisher: name: London South Bank University
Year: 1975

description: The theory of guided waves in straight and curved ducts of rectangular cross-section is developed. The propagation of waves in curved bends is considered in some detail with particular reference to source properties and their effects on the propagation of modes higher than the fundamental one. One of the problems encountered is the calculation of the angular wave numbers in the curved sections. Previous methods used for finding these are reviewed and the conclusion is reached that they are inadequate for bends of moderate curvature, particularly for the fundamental mode. Methods for calculating numerical values of Bessel functions and their derivatives are developed to cover a wide range of order and argument. Programs have been written for a small computer to give results of a fair degree of accuracy over most of the field of values. The angular wave numbers, which are the roots of the governing equations, are found by Newton's method. To define the sound field in the straight sections of duct a single mode source was used (generally the first cross mode) in order to give a clear picture of the mechanics of propagation. It is suggested that the sound pressure field in the straight duct immediately prior to the bend may be regarded as defining adequately the source for the bend. The differences in the forms of sound pressure distribution between straight and curved sections causes generation of extra modes. The modal amplitude constants may be calculated from the use of orthogonal properties of the cylinder functions with respect to order. In the straight section following the bend the process is similar: the sound pressure field at the end of the bend acts as a source for the following straight section. The modal amplitude constants are calculated as before but due allowance must be made for the phase difference between the modes. The interaction between the modes in the bend and following straight sections is demonstrated by calculating the distributions of sound pressure level across successive sections in the direction of propagation. Extensive experimental Results are reported for bends of varying angular length and for duct systems of two different materials. The agreement between the measured distributions of sound pressure level and predicted values is fair.

description: The intermittent dissipation of interstellar turbulence is an important energy source in the diffuse ISM. Though on average smaller than the heating rates due to cosmic rays and the photoelectric effect on dust grains, the turbulent cascade can channel large amounts of energy into a relatively small fraction of the gas that consequently undergoes significant heating and chemical enrichment. In particular, this mechanism has been proposed as a solution to the long-standing problem of the high abundance of CH+ along diffuse molecular sight lines, which steady-state, low temperature models under-produce by over an order of magnitude. While much work has been done on the structure and chemistry of these small-scale dissipation zones, comparatively little attention has been paid to relating these zones to the properties of the large-scale turbulence. In this paper, we attempt to bridge this gap by estimating the temperature and CH+ column density along diffuse molecular sight-lines by post-processing 3-dimensional MHD turbulence simulations. Assuming reasonable values for the cloud density (30 / cm^3), size (20 pc), and velocity dispersion (2.3 km / s), we find that our computed abundances compare well with CH+ column density observations, as well as with observations of emission lines from rotationally excited H2 molecules.

description: We studied the electronic and magnetic dynamics of ferromagnetic insulating BaFeO3 thin films by using pump-probe time-resolved resonant x-ray reflectivity at the Fe 2p edge. By changing the excitation density, we found two distinctly different types of demagnetization with a clear threshold behavior. We assigned the demagnetization change from slow (~ 150 ps) to fast (< 70 ps) to a transition into a metallic state induced by laser excitation. These results provide a novel approach for locally tuning magnetic dynamics. In analogy to heat assisted magnetic recording, metallization can locally tune the susceptibility for magnetic manipulation, allowing to spatially encode magnetic information.

description: A protocol based on quantum error correction based characterization of quantum dynamics (QECCD) is developed for quantum process tomography on a two-qubit system interacting dissipatively with a vacuum bath. The method uses a 5-qubit quantum error correcting code that corrects arbitrary errors on the first two qubits, and also saturates the quantum Hamming bound. The dissipative interaction with a vacuum bath allows for both correlated and independent noise on the two-qubit system. We study the dependence of the degree of the correlation of the noise on evolution time and inter-qubit separation.

description: The solar chromosphere contains thin, highly dynamic strands of plasma known as spicules. Recently, it has been suggested that the smallest and fastest (Type II) spicules are identical to intermittent jets observed by the Interface Region Imaging Spectrograph. These jets appear to expand out along open magnetic field lines rooted in unipolar network regions of coronal holes. In this paper we revisit a thirty-year-old idea that spicules may be caused by upward forces associated with Alfven waves. These forces involve the conversion of transverse Alfven waves into compressive acoustic-like waves that steepen into shocks. The repeated buffeting due to upward shock propagation causes nonthermal expansion of the chromosphere and a transient levitation of the transition region. Some older models of wave-driven spicules assumed sinusoidal wave inputs, but the solar atmosphere is highly turbulent and stochastic. Thus, we model this process using the output of a time-dependent simulation of reduced magnetohydrodynamic turbulence. The resulting mode-converted compressive waves are strongly variable in time, with a higher transition region occurring when the amplitudes are large and a lower transition region when the amplitudes are small. In this picture, the transition region bobs up and down by several Mm on timescales less than a minute. These motions produce narrow, intermittent extensions of the chromosphere that have similar properties as the observed jets and Type II spicules.

description: Reactive oxygen species and other free radicals, together with glucose and its metabolites are believed to play important roles in the aging process. The carbohydrate components of glycosylated proteins are important in mediating cell-cell interactions and a role has been suggested for them in the aging process. Erythrocytes are critical cells in the human body, heavily glycosylated and relatively easily available and so are good candidates to yield insights into how patterns of glycosylation change with age and disease. It has been claimed, based on a periodic acid Schiff assay, that human aging is associated with a decline of erythrocyte surface sialic acids. Plant lectins allow for more specific assays for glycans, including determining the linkage of sialic acids and analysis of single cells by flow cytometry.

description: We discuss flavor symmetries in left-right symmetric theories. We show that such frameworks are a different environment for flavor symmetry model building compared to the usually considered cases. This does not only concern the need to obey the enlarged gauge structure, but also more subtle issues with respect to residual symmetries. Furthermore, if the discrete left-right symmetry is charge conjugation, potential inconsistencies between the flavor and charge conjugation symmetries should be taken care of. In our predictive model based on $A_4$ we analyze the correlations between the smallest neutrino mass, the atmospheric mixing angle and the Dirac CP phase, the latter prefers to lie around maximal values. There is no lepton flavor violation from the Higgs bi-doublet.

description: We analyse a non-equilibrium exclusion process in which particles are created and annihilated in pairs and hop to the the right or to the left with different transition rates, $p$ and $q$, respectively. We have studied the dynamics of a single particle, and exactly determined the entropy, entropy production rate and entropy flux as functions of time. In the system of many particles, we have characterised the system by its probability distribution, as well as the entropy production rate in close forms, provided that $p+q$ equals the sum of dimers creation and annihilation rates. The general case, where this constraint is absent, was considered at pair approximation level; the time-dependent behaviour of the system was analysed, and the stationary entropy production was determined. In all cases, in the stationary regime, we showed that the entropy production rate is a bilinear form in the current of particles and the force $\ln(p/q)$.

Haunting stories of abuse: revealing ghosts through critical performance ethnography
Creators: name: Gratch, Ariel
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: This project explores what it means to be haunted by a history of abuse. Through critical performance ethnography I explore the incommunicability of intimate abuse. In an effort to make meaning out of these acts, we work to label past experiences and place them into an easily explainable context. In so doing, many mundane acts of abuse might not be viewed as legitimate by the people who experienced these acts of abuse. This project employed a performance centered research method. A staged performance was created that juxtaposed ethnographic research, theories of victimization, memory, and haunting, and a traditional ghost story. This opened up conversations of how histories of abuse continue to effect people long after the physical abuse stops. This analysis suggests that focusing on the relationship aspect of intimate abuse offers methods of praxis that are absent when our focus rests on labels.

description: The whitening and opacifying agent titanium dioxide (TiO2) is used worldwide in various foodstuffs, toothpastes and pharmaceutical tablets. Its use as a food additive (E171 in EU) has raised concerns for human health. Although the buccal mucosa is the first area exposed, oral transmucosal passage of TiO2 particles has not been documented. Here we analyzed E171 particle translocation in vivo through the pig buccal mucosa and in vitro on human buccal TR146 cells, and the effects on proliferating and differentiated TR146 cells. In the buccal floor of pigs, isolated TiO2 particles and small aggregates were observed 30 min after sublingual deposition, and were recovered in the submandibular lymph nodes at 4 h. In TR146 cells, kinetic analyses showed high absorption capacities of TiO2 particles. The cytotoxicity, genotoxicity and oxidative stress were investigated in TR146 cells exposed to E171 in comparison with two TiO2 size standards of 115 and 21 nm in diameter. All TiO2 samples were reported cytotoxic in proliferating cells but not following differentiation. Genotoxicity and slight oxidative stress were reported for the E171 and 115 nm TiO2 particles. These data highlight the buccal mucosa as an absorption route for the systemic passage of food-grade TiO2 particles. The greater toxicity on proliferating cells suggest potential impairement of oral epithelium renewal. In conclusion, this study emphasizes that buccal exposure should be considered during toxicokinetic studies and for risk assessment of TiO2 in human when used as food additive, including in toothpastes and pharmaceutical formulations.

description: The interaction between partners is an essential part of the training process in police use of force training. In order to simulate training tasks, that are both representative and motivating, the level of contact when receiving and delivering punches and kicks is an important issue. The current study investigates the preferred level of contact of trainees in police use of force training settings. For that purpose, 132 recruits of the Hessian State police were interviewed via an online questionnaire. The results showed, that (a) participants prefer higher levels of contact when using a pad to practice punches and kicks and (b) female officers prefer lower levels of contact in sparring exercises compared to male officers. The findings highlight the different needs of participants in training settings with regards to different situations. As such, the results provide valuable insights for police use of force coaches to manage and address contact intensity in training simulations.

description: Reports on the cytotoxicity of diamond nanoparticles (ND) are ambiguous and depend on the physicochemical properties of the material and the tested cell lines. Thus, the aim of this research was to evaluate the influence of thirteen types of diamond nanoparticles, differing in production method, size, and surface functional groups, on their cytotoxicity against four tumor cell lines (T98G, U-118 MG, MCF-7, and Hep G2) and one non-tumor cell line (HFF-1). In order to understand the dependence of diamond nanoparticles on physicochemical properties, the following parameters were analyzed: viability, cell membrane damage, morphology, and the level of intracellular general ROS and mitochondrial superoxide. The performed analyses revealed that all diamond nanoparticles showed no toxicity to MCF-7, Hep G2, and HFF-1 cells. In contrast, the same nanomaterials were moderately toxic for the glioblastoma T98G and U-118 MG cell lines. In general, the effect of the production method did not influence ND toxicity. Some changes in cell response after treatment with modified nanomaterials were observed, with the presence of carboxyl groups having a more detrimental effect than the presence of other functional groups. Although nanoparticles of different sizes caused similar toxicity, nanomaterials with bigger particles caused a more pronounced effect.

description: The growing evidence pointing at core-collapse supernovae as large dust producers makes young massive stellar clusters ideal laboratories to study the evolution of dust immersed into a hot plasma. Here we address the stochastic injection of dust by supernovae and follow its evolution due to thermal sputtering within the hot and dense plasma generated by young stellar clusters. Under these considerations, dust grains are heated by means of random collisions with gas particles which results on the appearance of infrared spectral signatures. We present time-dependent infrared spectral energy distributions which are to be expected from young stellar clusters. Our results are based on hydrodynamic calculations that account for the stochastic injection of dust by supernovae. These also consider gas and dust radiative cooling, stochastic dust temperature fluctuations, the exit of dust grains out of the cluster volume due to the cluster wind and a time-dependent grain size distribution.

description: The attention to rare earth oxide nanoparticles (NPs), including yttrium oxide (Y2O3), has increased in many fields due to their unique structural characteristics and functional properties. The aim of our study was to investigate the mechanisms by which bio-corona formation on Y2O3 NPs affects their environmental fate and toxicity. The Y2O3 NPs induced toxicity to freshwater filter feeder Daphnia magna at particle concentrations of 1 and 10 mg/L, regardless of particle size. Interactions between naturally excreted biomolecules (e.g. protein, lipids, and polysaccharides) derived from D. magna, and the Y2O3 NPs (30–45 nm) resulted in the formation of an eco-corona, which reduced their toxic effects toward D. magna at a particle concentration of 10 mg/L. No effects were observed at lower concentrations or for the other particle sizes investigated. Copper-zinc (Cu-Zn) superoxide dismutase, apolipophorins, and vitellogenin-1 proteins proved to be the most prominent proteins of the adsorbed corona, and possibly a reason for the reduced toxicity of the 30–45 nm Y2O3 NPs toward D. magna.

description: A new class of ultra-long duration (>10,000 s) gamma-ray bursts has recently been suggested. They may originate in the explosion of stars with much larger radii than normal long gamma-ray bursts or in the tidal disruptions of a star. No clear supernova had yet been associated with an ultra-long gamma-ray burst. Here we report that a supernova (2011kl) was associated with the ultra-long duration burst 111209A, at z=0.677. This supernova is more than 3 times more luminous than type Ic supernovae associated with long gamma-ray bursts, and its spectrum is distinctly different. The continuum slope resembles those of super-luminous supernovae, but extends farther down into the rest-frame ultra-violet implying a low metal content. The light curve evolves much more rapidly than super-luminous supernovae. The combination of high luminosity and low metal-line opacity cannot be reconciled with typical type Ic supernovae, but can be reproduced by a model where extra energy is injected by a strongly magnetized neutron star (a magnetar), which has also been proposed as the explanation for super-luminous supernovae.

description: Having satisfied nurses and well-perceived supervisor support is essential for achieving good organizational performance. Lack of these two influencing factors has been identified to cause a sentinel event in a Psychiatric Intensive Care Unit (PICU) in a tertiary teaching hospital in Indonesia. A Root Cause Analysis (RCA) investigation was conducted as a follow-up process within a week post the incidence. The investigation result has shown that lack of nurse satisfaction and supervisor support have contributed to the incident. Several reports have shown that the use of transformational leadership in the hospital setting will enhance nurses' satisfaction. As a recommendation to avoid the reoccurrence of the incident and enhance its outcome, the head nurse should perform transformational leadership combined with other management tools.

description: We develop a primal-dual algorithm that allows for one-step inversion of spectral CT transmission photon counts data to a basis map decomposition. The algorithm allows for image constraints to be enforced on the basis maps during the inversion. The derivation of the algorithm makes use of a local upper bounding quadratic approximation to generate descent steps for non-convex spectral CT data discrepancy terms, combined with a new convex-concave optimization algorithm. Convergence of the algorithm is demonstrated on simulated spectral CT data. Simulations with noise and anthropomorphic phantoms show examples of how to employ the constrained one-step algorithm for spectral CT data.

description: The Voronoi cell of any atom in a lattice is identical. If atoms are perturbed from their lattice coordinates, then the topologies of the Voronoi cells of the atoms will change. We consider the distribution of Voronoi cell topologies in two-dimensional perturbed systems. These systems can be thought of as simple models of finite-temperature crystals. We give analytical results for the distribution of Voronoi topologies of points in two-dimensional Bravais lattices under infinitesimal perturbations and present a discussion with numerical results for finite perturbations.

A Remark on the Second Neighborhood Problem

description: Seymour's second neighborhood conjecture states that every simple digraph (without digons) has a vertex whose first out-neighborhood is at most as large as its second out-neighborhood. Such a vertex is said to have the second neighborhood property (SNP). We define "good" digraphs and prove a statement that implies that every feed vertex of a tournament has the SNP. In the case of digraphs missing a matching, we exhibit a feed vertex with the SNP by refining a proof due to Fidler and Yuster and using good digraphs. Moreover, in some cases we exhibit two vertices with SNP.
