description: We study the spectrum of the Laplace operator of a complete minimal properly immersed hypersurface $M$ in $\R^{n+1}$. (1) Under a volume growth condition on extrinsic balls and a condition on the unit normal at infinity, we prove that $M$ has only essential spectrum consisting of the half line $[0, +\infty)$. This is the case when $\lim_{\tilde{r}\to +\infty}\tilde{r}κ_i=0$, where $\tilde{r}$ is the extrinsic distance to a point of $M$ and $κ_i$ are the principal curvatures. (2) If the $κ_i$ satisfy the decay conditions $|κ_i|\leq 1/\tilde{r}$, and strict inequality is achieved at some point $y\in M$, then there are no eigenvalues. We apply these results to minimal graphic and multigraphic hypersurfaces.

title: Concentrated Use Areas: Characteristics and Management Strategies on the Uinta-Wasatch-Cache National Forest
Creators: name: Maughan, Zachary F.
Publisher: name: Utah State University
Year: 2015

description: Dispersed recreation management is a form of management that has emerged over the past century of outdoor recreation management on public lands in the United States. Techniques used in dispersed recreation management seek to disperse recreation use, recreational areas, and their impacts across landscapes and ecosystems or to concentrate such use to areas that remain undeveloped. This study is a mixed-methods, descriptive study of dispersed recreation management on national forest lands. In particular, this study focuses on United States Forest Service (USFS) management Concentrated Use Areas (CUAs) on Uinta-Wasatch-Cache National Forest (UWCNF), as identified in the 2003 Revised Forest Plan of the Wasatch-Cache National Forest. A qualitative approach of inventorying past management actions, observing CUAs, and interviewing recreation managers and resource specialists on the UWCNF was used. The qualitative aspects of this study were also coupled with a quantitative analysis of Geographic Positioning System (GPS) based data using Geographic Information Systems (GIS) to better understand characteristics of CUAs and their management in dispersed recreation settings.
Overall, this study draws many conclusions involving the definition of, and management and design solutions for CUAs. CUAs can be described as easily accessible, flat areas adjacent to roads, with good access to water, and shade. These areas are often used for camping of various types, with trailers and groups being a predominant use. ATVs and motorized use are also associated with these areas. Use is generally considered high and continual during the summer season, with sites often being used year after year by families and groups of friends. Loss of vegetation, soil compaction, and soil erosion are common impacts attributed to concentrated recreational use.
Another finding was that recreation resource managers and resource specialists have similar views of what CUAs are and how they are managed. Management actions generally consist of both indirect and direct management actions focused on limiting environmental impacts caused by recreation uses. Management actions are conducted on both large and small scales within districts, and dispersed recreation protocol was found that called on management to reduce biophysical impacts. However, management techniques lack official targets and metrics for measuring the success of management. Design is also a component of CUA management. The design of CUAs generally consists of adapting user-created recreation areas into more structured and defined areas.
Public libraries as settings for the development of critical health literacy in children.
Creators: name: Jenkins, Catherine
Publisher: name: London South Bank University
Year: 2023
Subjects: critical health literacy; children’s health literacy; settings-based approach; supersetting approach

description: Health literacy enables people to access, understand, appraise, remember and use information about health. Critical health literacy is a domain of health literacy and enables individuals and communities to engage in social and political processes for action on the determinants of health. Promoting critical health literacy early in the life course may contribute to improved health outcomes in the long term. Yet children’s opportunities to develop critical health literacy are limited and tend to be school based. There are recognised barriers to implementing critical health literacy interventions in schools. The aim of this study is to broaden the range of settings based approaches available by exploring the potential role of public libraries as community-based supportive environments for children’s critical health literacy. The study was designed in consultation with a Children’s Advisory Group of eight children. The setting is a public library system in England. The theoretical and methodological framework is institutional ethnography. Semi-structured interviews were conducted with 13 children, and semi-structured text-elicitation interviews were conducted with 19 public library staff and community stakeholders. The data were analysed through the lens of a conceptual model based on the literature. The model provided an organising framework for the data and informed a keywords approach to analysis. The findings show that texts produced by the public library sector refer to health literacy support for local communities as part of the public library service offer, but the library was not perceived as a setting for health, and schools influence the health literacy development opportunities available for children there. Critical health literacy was seen as beyond the remit of the library, although one activity promoting critical health literacy was identified. This activity acknowledged the wider determinants of health, was accessible to children, involved children in how it was run, and facilitated children’s informed action for health. A revised conceptual model is proposed that identifies the necessary conditions, or antecedents, for public libraries to be a supportive environment for children’s critical health literacy development. The revised model situates the public library in a coordinated, multisetting (supersetting) approach with other settings where children spend time, including but not limited to schools. The study advances the theory and application of a supersetting approach to the development of critical health literacy in children and highlights the possibilities of non-traditional settings for health. It also contributes to the ongoing development of institutional ethnography and health literacy research with children.
title: Introducing Two New Weed Control Tools: A "Smart" Spray Wand and a Wildland Weed Treatment Time Model
Creators: name: Dayton, Bryan E.
Publisher: name: Utah State University
Year: 2015

description: Millions are spent managing invasive weeds on public lands each year. Wildland invasive weed treatment bids are based primarily on acreage or hours but can be influenced by variables that increase treatment time and cost. Often neither the agency contracting the treatment nor the contractor has a clear idea of the amount of time that will be involved based on these variables. This makes it difficult to develop an accurate budget or bid for invasive weed control projects. It also limits managers in seeking funding and justifying treatment costs.
A model has been developed that can predict herbicide application time due to four variables, weed canopy cover, slope, land cover, and weed visibility. Other variables were explored.
The “smart” spray wand (SSW) is a new precision tool used to develop this model. The SSW is a spray wand with an integrated GPS and a flow meter for use with any type of spray system. The wand records the GPS location, herbicide flow,application time, and associated data of each treatment spray point. This information provided necessary data for the treatment time model. Weed control total treatment time (TTot) was hypothesized to include both treatment time (Tt) and rest time (Rt). The development and benefits of a wildland weed treatment time model are discussed.
An accurate treatment time model could 1) establish an accurate standard for contractors and land managers, 2) assist in planning and managing limited treatment resources, and 3) justify funding requests and expenditures.
The primary influence of the model is due to weed canopy cover (p=2=0.5607), with smaller impacts by other variables. If canopy cover, slope, land cover, and weed visibility can be obtained for a weed control project, the model can be used.

description: We report two complementary measurements of the WW+WZ cross section in the final state consisting of an electron or muon, missing transverse energy, and jets, performed using p\bar{p} collision data at sqrt{s} = 1.96 TeV collected by the CDF II detector. The first method uses the dijet invariant mass distribution while the second more sensitive method uses matrix-element calculations. The result from the second method has a signal significance of 5.4 sigma and is the first observation of WW+WZ production using this signature. Combining the results gives sigma_{WW+WZ} = 16.0 +/- 3.3 pb, in agreement with the standard model prediction.

description: In several members of the ferro-pnictides, spin density wave (SDW) order coexists with superconductivity over a range of dopings. In this letter we study the anomalous magnetic Zeeman response of this coexistence state and show that it can be used to confirm the extended s-wave gap structure as well as structure of superconducting (SC) gap in coexisting phase. On increasing the field, a strongly anisotropic reduction of SC gap is found. The anisotropy is directly connected to the gap structure of superconducting phase. The signature of this effect in quasiparticle interference measured by STM, as well as heat transport in magnetic field is discussed. For the compounds with the nodal SC gap we show that the nodes are removed upon formation of SDW. Interestingly the size of the generated gap in the originally nodal areas is anisotropic in the position of the nodes over the Fermi surface in direct connection with the form of SC pairing.

description: It is has been long known that the curved space in the presence of gravitation can be described as a non-homogeneous anisotropic medium in flat geometry with different constitutive equations. In this article, we show that the eigenpolarizations of such medium can be exactly solved, leading to a pseudo-isotropic description of curved vacuum with two refractive index eigenvalues having opposite signs, which correspond to forward and backward travel in time. We conclude that for a rotating universe, time-reversal symmetry is broken. We also demonstrate the applicability of this method to Schwarzschild metric and derive exact forms of refractive index. We derive the subtle optical anisotropy of space around a spherically symmetric, non-rotating and uncharged blackhole in the form of an elegant closed form expression, and show that the refractive index in such a pseudo-isotropic system would be a function of coordinates as well as the direction of propagation. Corrections arising from such anisotropy in the bending of light are shown and a simplified system of equations for ray-tracing in the equivalent medium of Schwarzschild metric is found.

title: Aqueous Solvation Method for Recombinant Spider Silk Proteins
Creators: name: Jones, Justin A.
Publisher: name: Utah State University
Year: 2015

description: Two major hurdles face the production of recombinant spider silk protein (rSSp) based materials. First, the production of sufficient quantities of rSSp has proven difficult due to their highly repetitive nature and protein size (>250kDa). Secondly, rSSp and native silks are practically insoluble in water based solutions, necessitating the use of harsh organic solvents that can remain in the material after production. While others are working on solving production problems, this dissertation demonstrates a novel aqueous solubilization method that is rapid (minute) and results in near 100% solubilization of the rSSp. From this new solubilization method films, foams, gels (hydrogels and lyogels), adhesives, coatings and fibers have been produced as well as the previously unreported sponge. All of these novel materials were derived from entirely aqueous solutions with and without minor additives to influence the final physical state of the rSSp.

description: We study second-order perturbations for a general non-canonical scalar field, minimally coupled to gravity, on the unperturbed FRW background, where metric fluctuations are neglected a priori. By employing different approaches to cosmological perturbation theory, we show that, even in this simplified set-up, the second-order perturbations to the stress tensor, the energy density and the pressure display potential instabilities, which are not present at linear order. The conditions on the Lagrangian under which these instabilities take place are provided. We also discuss briefly the significance of our analysis in light of the possible linearization instability of these fields about the FRW background.

title: Two Types of Conformal Antennas for Small Spacecrafts
Creators: name: Tariq, Salahuddin
Publisher: name: Utah State University
Year: 2015

description: Conformal antennas have widespread applications in communication systems for vehicular bodies, aircrafts, and spacecrafts etc. They are non-protruding and can arbitrarily take any shape on the surface where they are etched. This thesis is a summary of two main projects. The first project employs a conformal array of four S-band and four GPS-band antennas for sub-payload of a sounding rocket. The sub-payload is a small cylinder and therefore the eight conformal antennas are based on curved patch geometry. The second project employs a conformal antenna for a CubeSat. The antenna is based on a cavitybacked slot and therefore can be conveniently integrated around the surface-mount solar cells of the CubeSat. Such an integration has enormous merits for CubeSat because there is no competition between the antennas and solar cells for the limited surface real estate. The antenna design operates UHF band with circular polarization, making it the first UHF nondeployed antenna for CubeSats. For both projects, problems such as isolation, impedance bandwidth, axial ratio bandwidth, and EMI shielding have been analyzed and resolved. This thesis work yields a prototype-ready design for the first project, and a final prototype and measurements for the second project.
Contrasting doctrines of the heart : a study of egocentricity and benevolence in novels by Fielding and Sterne
Creators: name: Hagan, John Christian
Publisher: name: University of British Columbia
Year: 2012

description: In 1651, Thomas Hobbes published his Leviathan. In it he analyses the passions and behaviour of men in an emerging market or competitive society. By posing his hypothetical "state of nature," he draws the conclusion that man is essentially a self-motivated creature. Lord Ashley Cooper, the third Earl of Shaftesbury, reacted to the picture of man drawn by Hobbes. In Characteristics of Men, Manners, Opinions, and Times, first published in 1709, Shaftesbury analyses the affections or passions and concludes that man is essentially benevolent. Unlike the Hobbesian picture, the Shaftesburian analysis shows man as outward-oriented, seeking the good and company of others. These theories or the doctrines of the heart (as I call them for the purpose of this thesis) were current in the eighteenth century and at a time when Fielding and Sterne wrote Tom Jones and The Life and Opinions of Tristram Shandy, Gentleman respectively. The doctrines are reflected substantially in both novels. In Tom Jones, for example, Tom becomes the epitome of the doctrine of benevolence in his persistent performance of good works; Blifil, in his selfish attempts to supplant Tom, displays Hobbesian egocentricity. Uncle Toby and Mr. Walter Shandy each reflect aspects of both doctrines in Tristram Shandy. It is my intention to show in this thesis that the doctrines of egocentricity and benevolence inform both Tom Jones and Tristram Shandy, and that Fielding and Sterne react critically to the teaching of Hobbes and Shaftesbury in the process of their artistic creation. I shall approach the discussion chiefly by way of character analysis thus showing how the behaviour of the main figures in the novels suggests the thoughts of the philosophers. But the novelists' vision becomes clearer to the reader when it is seen in direct relation to the style of their works. In addition to the character analysis , therefore, I shall emphasize the narrative technique of each author, such as, the "comic- epic prose" of Fielding, the digressions as well as the "Shandean rhetoric" of Sterne, and attempt to illustrate how the style strengthens the awareness of the artistic vision.
title: Systems Modeling and Economic Analysis of Photovoltaic (PV) Powered Water Pumping Brackish Water Desalination for Agriculture
Creators: name: Jones, Michael A.
Publisher: name: Utah State University
Year: 2015

description: Global growing demand for agricultural production has put increased pressure on freshwater resources in various global locations. Many areas have saline groundwater resources which have not been utilized for agriculture due to the economics associated with water pumping and desalination. Limited availability to electricity and high operational costs of diesel generators are major obstacles to utilization of these resources. Reduced costs associated with large-scale renewable energy have renewed interest in understanding the potential impacts of developing distributed photovoltaic (PV) powered water pumping and desalination systems for agriculture. In order to determine the economic feasibility of solar-powered water pumping and desalination for agriculture, an engineering system model that performs hourly simulations of direct-coupled PV pumping and desalination systems by integrating environmental resource data and industrial component performance data was developed. Optimization algorithms were created to identify the best membrane type, control method and reverse osmosis system configuration for a given set of locational parameters. Economic analysis shows that PV-powered systems are more economical than diesel-powered systems for water pumping, with water desalination costs for PV- and diesel-powered systems being comparable. Grid-powered systems are able to pump and desalinate water for a lower cost than PV or diesel for all cases evaluated. A sensitivity analysis is performed to generalize results for different input parameters and illustrate the impact of input variables on water unit costs. Several case studies in the Jordan Valley were evaluated to illustrate the economic viability of solar-based systems with simulation results including a direct comparison to diesel- and grid-connected alternatives. Results indicate that under fair environmental conditions and irrigating greenhouse vegetables, the PV-, diesel-, and grid-powered systems produce favorable internal rates of return of 40%, 84%, and 248%, respectively. Under poor environmental conditions and less profitable crops the PV-, diesel-, and grid-powered systems all result in negative internal rates of return, illustrating the need for optimal location and crop selection for system implementation.

description: Normal surface theory is a central tool in algorithmic three-dimensional topology, and the enumeration of vertex normal surfaces is the computational bottleneck in many important algorithms. However, it is not well understood how the number of such surfaces grows in relation to the size of the underlying triangulation. Here we address this problem in both theory and practice. In theory, we tighten the exponential upper bound substantially; furthermore, we construct pathological triangulations that prove an exponential bound to be unavoidable. In practice, we undertake a comprehensive analysis of millions of triangulations and find that in general the number of vertex normal surfaces is remarkably small, with strong evidence that our pathological triangulations may in fact be the worst case scenarios. This analysis is the first of its kind, and the striking behaviour that we observe has important implications for the feasibility of topological algorithms in three dimensions.

title: Risk Characterization from Multipathway Exposure Associated with Land Applying Biosolids by Accounting for Multimedia Mass Loss
Creators: name: Kumarasamy, Karthik
Publisher: name: Utah State University
Year: 2015

description: For over two decades the 40 CFR Part 503 has been the regulatory framework guiding land application of biosolids in the US. During this period public perception about the practice has worsened as evidenced by increases in partial and full biosolids land application bans across the US. In this work, the Multimedia, Multipathway and Multi-receptor Risk Assessment (3MRA) model was applied to four biosolids land application sites across the US (two sites in WA, one site each in VA and GA) to evaluate human health risk concerns from regulated (As and Cd) and non-regulated (B(a)P and DEHP) chemical constituents present in biosolids. The excess cancer risk from ingesting soil contaminated with As and Cd was higher than 1x10-6 when accounting for the background concentration. However, after separating the risk to reflect just the land application practice, the excess cancer risk estimates for the soil ingestion pathway were well below the acceptable risk criteria (several orders of magnitude lower). The non-cancer risk, for both As and Cd, was below 1. As and Cd remained mostly in the zone of biosolids incorporation. The combined As and Cd mass lost to all pathways for a 20-year consecutive application scenario was less than 15%. The classes of organic environmental toxins evaluated also did not cause concern. Both B(a)P and DEHP aerobically degraded and less than 3% remained in the zone of biosolids incorporation after a 100-year consecutive biosolids application based on model predictions. Scenarios considering biosolids application at typical agricultural rates did not result in groundwater impairment for the sites evaluated; however, scenarios with biosolids applications that are similar to a surface disposal practice resulted in groundwater impairment. In addition to this work, sites across the US (in WA, VA and GA) were evaluated for groundwater impairment scenarios. The results from this effort clearly point towards no additional excess cancer (>1x10-6) or non-cancer (HQ>1) health risks associated specifically with the practice of land application of biosolids for agricultural production for the sites and chemical contaminants evaluated.

We propose a family of models that can simulate von Neumann measurements in the x-y plane of the Bloch sphere on n-partite GHZ states using only bipartite nonlocal boxes. For the tripartite and fourpartite states, the models use only bipartite nonlocal boxes; they can be translated into classical communication schemes with finite average communication cost.

Exclusive rare $B_s\to (K,η,η')\ell^+\ell^-$ decays in the light-front quark model

description: Using the light-front quark model, we calculate the transition form factors, decay rates, and longitudinal lepton polarization asymmetries for the exclusive rare $B_s\to (K,η^{(\prime)})(\ell^+\ell^-,ν_{\ell}\bar{ν_{\ell}}$ ($\ell=e,μ,τ$) decays within the standard model, taking into account the $η-η'$ mixing angle. For the mixing angle $θ=-20^{\circ}$ ($-10^{\circ}$) in the octet-singlet basis, we obtain ${\rm BR}(B_s\to η\sumν_{\ell}\barν_{\ell})=1.1 (1.7)\times 10^{-6}$, ${\rm BR}(B_s\to ημ^+μ^-)=1.5 (2.4)\times 10^{-7}$, ${\rm BR}(B_s\to ητ^+τ^-)=3.8 (5.8)\times 10^{-8}$, ${\rm BR}(B_s\to η'\sumν_{\ell}\barν_{\ell})=1.8 (1.3)\times 10^{-6}$, ${\rm BR}(B_s\to η'μ^+μ^-)=2.4 (1.8)\times 10^{-7}$, and ${\rm BR}(B_s\to η'τ^+τ^-)=3.4 (2.6)\times 10^{-8}$, respectively. The branching ratios for the $B_s\to K(ν_{\ell}\bar{ν_{\ell}},\ell^+\ell^-)$ decays are at least an order of magnitude smaller than those for the $B_s\to η^{(\prime)}(ν_{\ell}\bar{ν_{\ell}},\ell^+\ell^-)$ decays. The averaged values of the lepton polarization asymmetries for $B_s\to (K,η^{(\prime)})\ell^+\ell^-$ are obtained as $\la P^K_L\ra_μ=\la P^η_L\ra_μ=\la P^{η'}_L\ra_μ=-0.98$, $\la P^K_L\ra_τ=-0.24$, $\la P^η_L\ra_τ=-0.20$ and $\la P^{η'}_L\ra_τ=-0.14$, respectively.

title: Framing Fracking: Media Coverage of Unconventional Oil and Gas Development in South Texas
Creators: name: Potterf, Jebadiha E.
Publisher: name: Utah State University
Year: 2014

description: There is an oil boom occurring in the United States reminiscent of the production booms of the early 20th century. As the use of unconventional gas and oil extraction practices explode across the US, understanding how the affected public perceives this development is vital. As a major influence on public opinion, understanding the way this development is being framed by interest groups and the news media is an important step in understanding public perceptions. This study utilizes framing theory as a method for investigating how online and print media coverage of this development utilizes the frames promoted by actors on either side of this issue. Content analysis is used to examine national level industry and opposition websites to inductively uncover the thematic frames used by these actors in the public debate surrounding unconventional development. These frames are subsequently used to analyze newspaper articles published in metropolitan cities of Eagle Ford Shale region to discover how these or other frames are utilized in their coverage of the unconventional development occurring in the Eagle Ford Shale. I found that the pro-development frames used by proponent interest groups matched very closely with the pro-development frames used in the news media. Conversely, the way opposition frames are used by the opponent interest groups and in the news media display much more variance. These findings have implications for several theories seeking to explain the influence of interest groups on news coverage. And are important for fully understanding how the perceptions of residents regarding oil and gas activity are formed. While this research did not take the step to compare the news media frames used to the individual frames residents use to understand this activity, it does address a lacuna in the research on unconventional development by examining the way interest groups and the media frame their communications pertaining to the issue.

description: We study the dissipative effects of baryon physics on cosmic statistics at small scales using a cosmological simulation of a (50 Mpc/h)^3 volume of the universe. The MareNostrum simulation was performed using the AMR code RAMSES, and includes most of the physical ingredients which are part of the current theory of galaxy formation, such as metal-dependent cooling and UV heating, subgrid modelling of the ISM, star formation and supernova feedback. We re-ran the same initial conditions for a dark matter only universe, as a reference point for baryon-free cosmic statistics. In this paper, we present the measured small-scale amplification of sigma^2 and S_3 due to baryonic physics and their interpretation in the framework of the halo model. As shown in recent studies, the effect of baryons on the matter power spectrum can be accounted for at scales k

We also show that the ground and the first excited states of this system have remarkably the same properties of the highly excited Rydberg states of a hydrogen-like atom i.e. a high sensitivity to the external perturbations and long radiative lifetimes.

title: Couple Leisure Time: Building Bonds Early in Marriage Through Leisure

description: Participation in couple leisure is related to marital satisfaction as well as lower divorce rates; however, Americans seem to have less time available to participate in couple leisure and may have a harder time attaining role balance. There is currently limited research about how role balance may affect leisure as well as how couples manage to balance their leisure time with their other responsibilities, ensuring they have time to spend together in high interaction leisure. We also know very little about other possible benefits couples may experience as a result of participating in couple leisure and the factors that may either facilitate or constrain positive leisure. Using a qualitative approach to data collection and analysis, and informed by symbolic interaction theory, I interviewed nine couples in order to explore the phenomenon of newlywed couple leisure, and address these issues. Couples found significant benefits and meaning through participation in couple leisure activities. They also perceived that participation in leisure together increased satisfaction with their marriages. Many factors were found to constrain or facilitate a positive leisure experience, including time, money, and others. It was found that role balance plays a large part in finding time to participate in leisure as a couple. Being able to role balance helped couples to better enjoy the benefits and meaning couple leisure provided.

description: We investigate the validity of the quasar - radio galaxy unification scenario and detect dust tori within radio galaxies of various types. Using VISIR on the VLT, we acquired sub-arcsecond (~0.40") resolution N-band images, at a wavelength of 11.85 micron, of the nuclei of a sample of 27 radio galaxies of four types in the redshift range z=0.006-0.156. The sample consists of 8 edge-darkened, low-power Fanaroff-Riley class I (FR-I) radio galaxies, 6 edge-brightened, class II (FR-II) radio galaxies displaying low-excitation optical emission, 7 FR-IIs displaying high-excitation optical emission, and 6 FR-II broad emission line radio galaxies. Out of the sample of 27 objects, 10 nuclei are detected and several have constraining non-detections at sensitivities of 7 mJy, the limiting flux a point source has when detected with a signal-to-noise ratio of 10 in one hour of source integration. On the basis of the core spectral energy distributions of this sample we find clear indications that many FR-I and several low-excitation FR-II radio galaxies do not contain warm dust tori. At least 57+-19 percent of the high-excitation FR-IIs and almost all broad line radio galaxies display excess infrared emission, which must be attributed to warm dust reradiating accretion activity. The FR-I and low-excitation FR-II galaxies all possess low efficiencies, calculated as the ratio of bolometric and Eddington luminosity log (L_bol/L_Edd) < -3. This suggests that thick tori are absent at low accretion rates and/or low efficiencies. We argue that the unification viewing angle range 0-45 degrees of quasars should be increased to ~60 degrees, at least at lower luminosities.

title: Persistence of Engineering Undergraduates at a Public Research University
Creators: name: Meyer, Matthew
Publisher: name: Utah State University

description: This mixed-methodological study determined which factors contributed to undergraduate student attrition, and evaluated reasons ten undergraduate engineering students failed to complete their engineering degree at a major western research university. Institutional data were collected on engineering students over a multi-year period. These data were separated into groups of engineering students who persisted to the Junior year of their undergraduate engineering program (persisters), and those students who left their engineering program before their Junior year (nonpersisters). A quantitative analysis comparing these two groups of students uncovered significant predictors of persistence/nonpersistence in the engineering program. Qualitative inquiry was used to identify factors leading to nonpersistence from the perspective of ten nonpersisting student volunteers from the institutional data population. Together, the quantitative and qualitative methods of inquiry formed a mixed-methodological study which provided a vivid picture of the challenges facing a major western research university regarding persistence of engineering undergraduates.
Descriptive and inferential statistical analysis of the institutional data collected on engineering undergraduate students uncovered several factors predictive of persistence/ nonpersistence. These include projected age at graduation, high school GPA and ACT scores, residency status, scholarship, and financial aid.
Common themes for ten students who dropped out of engineering included individual factors such as poor academic performance, feeling unprepared for demands of the engineering program, difficulty fitting into engineering, and institutional factors such as disappointment with engineering advising. New concepts uncovered in this paper, which were not prevalent in existing research, include a deeply emotional attachment between participants and the concept of being an engineer, a deeper understanding of student’s sense of loss and failure, and their easy transition from engineering to another major.
Investigation of the composition of woodsmoke and methods for apportioning woodsmoke to air pollution in Launceston
Creators: name: Jordan, TB

description: Launceston, a city with a population of approximately 80,000 located in the north of Tasmania, Australia, regularly experiences high levels of air pollution during winter. Ambient `PM_(10)` (particulate matter with an aerodynamic diameter smaller than 10 micrometres) levels exceed the Australian 24-hour guideline of `50` `˜í¬¿g``/``m^3` around 20-40 times during the May to September period each year. This is generally attributed to residential woodburning, with approximately one third of households using woodheaters or open fireplaces. This thesis reports on investigations into characterising and quantifying the contribution of woodsmoke to wintertime air pollution in Launceston. An historical record of air quality in Launceston was reconstructed using polycyclicaromatic hydrocarbons (PAHs) as surrogates for air pollution in a dated sediment core taken from the upper Tamar Estuary. The overall depth profile showed that levels of PAHs began increasing at the end of the 19th century and have been relatively steady since the 1930s. Pyrogenic source ratios similar to woodburning were found in both atmospheric and sedimentary samples, although quantification of the woodburning contribution was not possible using PAHs alone. Factors affecting atmospheric sampling of PAHs were investigated, including the impact of sampling rate, the vapour-particle phase distribution on various components of the sampling system and degradation caused by different filter media. Because of the inability of PAHs to differentiate between fossil fuel and wood combustion there was a need to identify alternative tracers for wood combustion. A dilution tunnel was used to collect emissions from woodheaters operated with different airflow settings, and around 100 organic compounds were quantified. Although the majority of compounds were not detected in ambient air samples, levoglucosan was found to be not degraded in the atmospheric samples and was identified as a consistent tracer for woodsmoke. Levoglucosan concentrations in ambient `PM_(10)` indicated that woodheaters contributed about 80% of wintertime air pollution in Launceston. To validate the use of levoglucosan as a tracer for woodsmoke, the contribution of biomass and fossil fuel sources of carbon to Launceston ambient aerosols was determined by measuring the carbon-14 content using accelerator mass spectrometry. Fossil sources had a relatively low and constant input irrespective of the particulate loading, consistent with transport-related emissions. Conversely, the biomass input, most likely from woodsmoke, was found to increase linearly with particulate loading, and contributed around 97-99% of the total organic carbon fraction of Launceston wintertime PM10. A modified combustion method was developed for samples collected on borosilicate filter media.
title: African American Female Engineering Students' Persistence in Stereotype-threatening Environments: A Critical Race Theory Perspective

description: Due to the social context of engineering classrooms, stereotype threat (STT) may play an essential role in the dearth of African American females in engineering. Empirical studies have confirmed the deleterious effects STT has on students' performance. However, acceptance of STT as more than a laboratory phenomenon necessitates an in-depth understanding of how stigmatized groups experience being socially devalued and negatively stereotyped. In this qualitative investigation, Intersectionality and the Critical Race Theory tenet of counter-storytelling were applied to capture the voices of 10 African American women to comprehend how they resisted or overcame STT and persisted in engineering degree programs. Data were triangulated from two different semi-structured interviews and reading reactions submitted by each participant. Findings reveal four characteristic themes shared by the participants: (a)Proof Stereotype Threat Exists; (b) Primary Contributors of Stereotype Threat; (c) Secondary Factors; and (d) Tools for Persisting. Based on participants’ narratives, 6 recommendations are offered to assist African American female students combat STT and persist in engineering.

description: We prove the existence of a large class of one-parameter families of cosmological solutions to the Einstein-Euler equations that have a Newtonian limit. This class includes solutions that represent a finite, but otherwise arbitrary, number of compact fluid bodies. These solutions provide exact cosmological models that admit Newtonian limits but, are not, either implicitly or explicitly, averaged.
