Near-surface velocity reconstruction using surface wave inversion
Creators: name: Turner, Mark Alan
Publisher: name: University of Utah
Year: 2013

description: This thesis examines the feasibility of inverting surface waves in common shot point (CSP) scismic data for S- and P-wave velocities. Several approaches to surface wave inversion are examined: 1) separate Love and Rayleigh wave inversions for S- and P-wave velocities; 2) Love wave inversion for S-wave velocities that is then followed by Rayleigh wave inversion for S- and P-wave velocities; and 3) Love wave inversion for S-wave velocities that are then used in Rayleigh wave inversion for P-wave velocities. Inversion of synthetic data suggests that a combination of Love and Rayleigh wave inversion will provide the best results, especially if the Love waves are first used to reconstruct the S-wave velocities and the Rayleigh waves are then used to recover the P-wave velocities. Results also suggest that S-wave velocities inverted from Love waves may be more reliable than those from Rayleigh wave inversion, and that combining Love and Rayleigh wave inversion will provide the most accurate S-wave velocity reconstruction from field data. Density determination appears impractical using surface wave inversion. To verify the practicality of surface wave inversion, a nine-component surface wave experiment was performed in northeast Texas (courtesy of Arco Research). Tau-p and Fourier transforms are applied to the YY (cross-line component source recorded on cross-line component gcophones) and ZZ (z-component source recorded on z-component geophones) CSP gathers to recover Love and Rayleigh wave dispersion curves respectively. These curves show clearly the fundamental and higher harmonic modes from about 2 Hz to 14 Hz. Inversion of the fundamental mode data suggests shear velocities of 180 m/s near the surface with an abrupt change to 400 m/s within the first 10 meters followed by a gradual increase to 650 m/s at a depth of 65 meters. This is in good agreement with the shear velocities measured from vertical seismic profile (VSP) data. Results suggest that either Love or Rayleigh wave inversion can be used to provide shear wave statics and near-surface layer velocities, but that a combination of the two can improve the reliability of the velocity reconstruction.

Implications of antibiotic use for co-infections when a fitness trade-off for resistance is present

description: How much does indiscriminate antibiotic use promote the spread of antibiotic-resistant infections in a population? Assuming a fitness trade-off for resistance exists, it is possible for an antibiotic-vulnerable strain to outlast a resistant type within an untreated host carrying both. That means prudent treatment schemes can potentially manage resistance levels in the population-at-large. We use a compartmental ODE model incorporating a class of coinfected individuals to analyze the epidemiology. The Next Generation Operator method gives R0 for the two strains, and we perform invasion analysis for both types under different treatment schemes. Haphazard antibiotic use favors resistant strains by treating both singly-infected and co-infected people, while shrewd treatment targets those carrying the vulnerable strain only. According to the model, inattentively treating co-infected individuals significantly promotes resistance in a population.

Mormon cosmology

description: In 1894, John Hyrum Koyle began digging the Dream Mine, on a mountaintop in central Utah. Koyle, a Mormon bishop, had been shown where to dig, he said, by Moroni, the same heavenly messenger who had led Mormon founder Joseph Smith to unearth the golden plates. Moroni visited Koyle in a dream and showed him nine enormous caverns below the mountain, containing countless piles of gold. Moroni told Koyle that the gold  would remain hidden in the caves until an unspecified time preceding the Second Coming  of Jesus Christ. At that moment of chaos, Koyle and his followers would unearth the gold  and it would support the financially-troubled Mormon Church through the Last Days.  This thesis investigates the nature of belief in the Dream Mine, which remains fervent more than 100 years later. Although their dreams are perpetually deferred, believers tap into a rich vein of folklore that runs through Mormon cosmology. Over the  past thirty years, the Dream Mine has enabled believers to maintain a psychic link to a  magical past, as their church adapts to a changing, modern world. This thesis will consider how Dream Mine belief has evolved in a changing economic, political, and religious landscape, and demonstrate that the faithful find sustenance in the Mormon past while simultaneously embracing modern worldviews that extend beyond mainstream  Mormonism.

description: In a shocking 2013 policy shift, the Islamic Republic of Iran entered into negotiations with the United Nations Security Council in an attempt to resolve the longstanding issue of the alleged militaristic components of its nuclear energy program. Following decades of hostile tensions with Western powers, Iran's striking departure from traditional policy has garnered considerable attention from international media including the BBC, The New York Times, Thomson Reuters, and Al Jazeera. Current literature has primarily focused on the success of unilateral and multilateral sanctions in generating sufficient economic turmoil to force rapprochement. Yet the question remains, are sanctions responsible for the timing of the negotiations? To attain a more complete understanding of this issue, I conducted a tri-fold examination into Iran's economic health, shifting political climate, and social instability. In order to examine Iran's economy, I analyzed the impact of international sanctions and domestic economic policy through visual representations of various indicators including GDP, inflation rates, and oil exportation. Next, I examined the political developments Iran has experienced since the 2009 re-election of Mahmoud Ahmadinejad and how those developments contributed to the 2013 election of Hassan Rouhani and subsequent negotiations. Finally, I examined social factors by analyzing the differences in civic engagement surrounding the 2009 and 2013 elections and how shifting public sentiment contributed to the 2013 presidential election outcome. Ultimately, I argue that with such a narrow focus, the literature has failed to account for the unique convergence of factors that Iran experienced in the build-up to negotiations. While sanctions and poor domestic policy decisions contributed to Iran's worsening economy, the decline was not to such an extent that it adequately accounts for the timing of these talks. Additional factors, particularly Rouhani's election and his commitment to resolving the nuclear issue, created highly unique circumstances that led Iran to negotiate. In sum, as Iran and the world's major powers continue their mission to reach a more permanent solution to the issue of a nuclear Iran, this research and its comprehensive analysis of the convergence of Iran's economic, political, and social developments, offers a more comprehensive understanding of the situation.

description: We discuss the derivation of the electrodynamics of superconductors coupled to the electromagnetic field from a Lorentz-invariant bosonic model of Cooper pairs. Our results are obtained at zero temperature where, according to the third law of thermodynamics, the entropy of the system is zero. In the nonrelativistic limit we obtain a Galilei-invariant superconducting system which differs with respect to the familiar Schrödinger-like one. From this point of view, there are similarities with the Pauli equation of fermions which is derived from the Dirac equation in the nonrelativistic limit and has a spin-magnetic field term in contrast with the Schrödinger equation. One of the peculiar effects of our model is the decay of a static electric field inside a superconductor exactly with the London penetration length. In addition, our theory predicts a modified D'Alembert equation for the massive electromagnetic field also in the case of nonrelativistic superconducting matter. We emphasize the role of the Nambu-Goldstone phase field which is crucial to obtain the collective modes of the superconducting matter field. In the special case of a nonrelativistic neutral superfluid we find a gapless Bogoliubov-like spectrum, while for the charged superfluid we obtain a dispersion relation that is gapped by the plasma frequency.

Proving woman: From Heloise to Heloisian an examination of the authenticity debate surrounding the letters of Heloise of the Paraclete

Subjects: Héloïse, approximately 1095-1163 or 1164 -- Criticism and interpretation

description: This thesis examines and resists the tendency for a total subsumption of the identity of Heloise of the Paraclete, the 12th century abbess perhaps best known today for her tempestuous affair with Peter Abelard, within and under his identity. The authenticity debate surrounding the three letters addressed to Abelard from Heloise dated around 1132/1133 erases both the historical woman and her writings. Forgery claims made by scholars from 1975 onward postulate that the letters were forged by either Abelard himself or anonymous male imposters. One the one hand, it is by subsuming the historical woman underneath the created literary fiction of the romantic heroine that antifeminist scholars are able to argue for forgery. On the other hand, I resist the claims of scholars who wish to reclaim the historical woman for feminist discourse by purporting to reach the "real" inner life of Heloise, a move I view to be epistemologically unsound. Thus, after reviewing the process by which the historical woman came to be crowned la grande amoureuse of bourgeois literary imagination, I attempt to replace this problematically positivist conception of objectivity in historical research with a performative account of subject-object relations. This queer performative lens allows the radically affirming feminism of this remarkable 12th century woman to come into view.

Cancer metastasis

description: The PI3 kinase (PI3K)/AKT signaling pathway regulates many fundamental behaviors of the cell. If any of the key members of this pathway are deregulated, it can lead to malignant changes in the cell. AKT enhances the survival of cells by inhibiting pro-apoptotic processes, and promoting pathways for cell survival, important for cancer metastasis. Most solid tumors arise from the epithelium therefore I will address how differences in expression of pro-survival signals may affect epithelial tumors, or carcinomas. Our lab has found that to maintain constant cell numbers during epithelial homeostasis, excess cells are removed by extruding live cells that later die. Should misregulated PI3K/AKT cause cells to survive after extrusion, extrusion could enable cells to metastasize instead of eliminating excess cells, depending on the direction they extrude. If cells extrude the normal apical direction, then cells with upregulated survival signaling will still be eliminated through dead space. However, if cells extrude basal ly, they could access the underlying mesenchyme and initiate metastasis. Other oncogenic mutations have switched the direction of extrusion from predominantly apical to predominantly basal, therefore, we wondered if activation of AKT1 could also shift the direction of extrusion from apical to basal. I will test whether or not cancerous cells and non-cancerous cells over expressing AK.T1 can survive after they are extruded, and how downstream targets of the AKT1 pathway, like XlAP, affect directionality of extrusion and cell survival. This projcct is important for determining if common chemotherapies used on tumors over expressing AKT1 trigger invasion instead of ablation. However, I found that overexpression of AKT1 had no impact on the direction of extrusion or the ability of a cell to survive following extrusion.

description: Spouses of combat veterans with posttraumatic stress disorder have elevated  psychological distress, some of which has been explained by increased caregiver burden.  However, there is very little knowledge regarding intraindividual characteristics of these  spouses that may be related to their burden. The current study examined caregiver burden  in a sample of 102 spouses of reserve component troops deployed during Operation  Enduring Freedom/Operation Iraqi Freedom. Despite similar patterns of associations with  spousal traits, factor analyses revealed that items related to burden and distress each  loaded onto distinct factors, suggesting that they measure unique experiences. Burden  did, however, fully mediate the relation between service members' distress and spouses'  distress. Levels of burden were directly related to spouses' neuroticism and emotionfocused  coping, and marginally related to lower levels of self-efficacy and perceived  support from partners, although none of these factors were significant in a regression of  burden that included service members' distress. Finally, problem-focused coping  moderated the relation between service members' distress and spouses' burden, with the  association weakening as spouses endorsed higher amounts of these coping processes.  These results suggest that spouses' burden is primarily related to the degree of distress in  service members, but the promotion of adaptive coping styles in spouses may help  mitigate this link.

An analysis of relational communication in ongoing group systems
Creators: name: Ellis, Donald George
Publisher: name: University of Utah
Year: 2013

description: This research begins by examining four theoretical perspectives on interpersonal relationships. After reviewing reinforcement theories, cognitive theories, and psychoanalytic theories a set of propositions are set forth which direct attention to the importance of communication for the establishment and development of interpersonal relationships. This function of communication is termed relational communication. The study sought to develop and validate a coding scheme for measuring relational interaction by answering the following questions: (1) What types of relational interaction characterize decision-making groups and consciousness-raising groups?; (2) What, if any, are the differences in relational interaction between a decision-making group and a consciousness-raising group?' (3) Do patterns of relational interaction in either a decision-making group or a consciousness-raising group change over time; (4) Does the interaction produced by dyads in either a decision making group or consciousness-raising group differ from a group's total interaction. The audio-recordings of two decision-making groups and two consciousness-raising groups were subjected to a Markov statistical analysis. The results of the study suggest the following conclusions: (1) Decision-making groups function similarly and are characterized by equivalent symmetry, competitive symmetry, initiation cycles, and deference; (2) Consciousness-raising groups operate as unique interacting systems. While both groups are characterized by equivalent symmetry, one consciousness-raising group used initiation sequences and the other resorts to relational deference; (3) Decision-making interaction varies over time; (4) Only one of the consciousness-raising group had significant change over time; (5) Dyads formed by the leader and opinion deviate in decision-making groups differ from the total group interaction. Finally, the study proposes changes in the coding scheme and recommendations for future research.

description: Dissipative processes can drive different magnetic orders in quantum spin chains. Using a non-perturbative analytic mapping framework, we systematically show how to structure different magnetic orders in spin systems by controlling the locality of the attached baths. Our mapping approach reveals analytically the impact of spin-bath couplings, leading to the suppression of spin splittings, bath-dressing and mixing of spin-spin interactions, and emergence of non-local ferromagnetic interactions between spins coupled to the same bath, which become long-ranged for a global bath. Our general mapping method can be readily applied to a variety of spin models: We demonstrate (i) a bath-induced transition from antiferromangnetic (AFM) to ferromagnetic ordering in a Heisenberg spin chain, (ii) AFM to extended Neel phase ordering within a transverse-field Ising chain with pairwise couplings to baths, and (iii) a quantum phase transition in the fully-connected Ising model. Our method is non-perturbative in the system-bath coupling. It holds for a variety of non-Markovian baths and it can be readily applied towards studying bath-engineered phases in frustrated or topological materials.

description: Anemometry is the measurement of wind force and velocity. Though anemom-etry technology is fairly well developed, many velocity measurement devices are  expensive, large, and/or fragile. Due to these limitations, deploying large numbers of anemometers is difficult, and often unrealistic. The miniature optical-based velocity probe is a new instrument that o ers advantages over current state-of-the-art anemometers in terms of lower expense, lower power consumption and lighter weight. The probe consists of a high performance plastic optical  ber, a vertical-cavity surface-emitting laser (VCSEL), and a position sensitive detector (PSD). Light transmitted by the VCSEL shines through the free end of the optical   ber illuminating the surface of the PSD. A drag force, induced by an approach ow, causes the optical  ber to de  ect. The PSD measures the de ection of the optical  ber and outputs an analog voltage, which can be directly related to velocity through a calibration curve. Equations for the de ection and natural frequency of the optical  ber, along with numerical simulations in FLUENT were  used to make key design decisions in order to optimize the probe to meet the target speci cations for atmospheric research. Preliminary calibration experiments show that the velocity probe has the potential to be a viable replacement for other  research-quality anemometers.

Purification and physical characterization of intrinsically disordered lea protein from arabidopsis thaliana
Creators: name: Yoo, Chaekyung
Publisher: name: University of Utah
Year: 2014
Subjects: Intrinsically disordered proteins

description: For many decades, it was assumed that protein function was dependent on the ability of polypeptides to fold into stable three-dimensional structures specified by their amino acid sequences. But since about 2000, it has become apparent that there are functional proteins, or portions of proteins, that are highly disordered in their functional state. Members of this class of proteins, known as intrinsically disordered proteins (IDPs), do not form unique folded structures in isolation, though portions of many fold upon binding other molecules. It is estimated that approximately 30% of eukaryotic proteins contain at least one disordered region greater than 50 residues. IDPs have been found to participate in a large number of cellular processes, including transcriptional regulation and signal transduction. In many cases, they appear to act as flexible linkers between more rigid structures. Late embryogenesis abundant (LEA) proteins are a large family of IDPs that are expressed at high levels during the later stages of plant seed development. Dehydrins are subfamily of LEA proteins that are believed to play a role in protecting cellular contents from the effects of dehydration. The goal of this project was to study the physical traits of XERO2, a 193 amino acid residue LEA protein from the model plant Arabidopsis thaliana. BL21 E. coli cells were transformed with a synthetic XERO2 gene, and the expressed protein was isolated using a new purification process that included chromatography on phosphocellulose. This method yielded ~30 mg of protein per liter of bacterial culture with a purity of ~90%. The average hydrodynamic radius (RH) of XERO2 was estimated using size exclusion chromatography (SEC) and calibration with well-characterized globular proteins. In phosphate buffer at pH 7.2, RH was determined to be approximately 32 Å, a value that is intermediate between those expected for a 193-residue fully unfolded polypeptide (42 Å) and a globular protein of the same size (22 Å). Comparisons with other IDPs suggest that the degree of expansion of XERO2 lies well within the observed range for this class of proteins. Preliminary small-angle X-ray experiments also indicate that XERO2 is extensively disordered and has a significant tendency to aggregate at concentrations of about 10 mg/mL.

description: We study the dynamical evolution of quasi-circular equal mass massive black hole binaries embedded in circumbinary discs from separations of $\sim 100R_{\rm g}$ down to the merger, following the post merger evolution. The binary orbit evolves owing to the presence of the gaseous disc and the addition of Post-Newtonian (PN) corrections up to the 2.5 PN order, therefore including the dissipative gravitational wave back-reaction. We investigate two cases of a relatively cold and warm circumbinary discs, with aspect ratios $H/R=0.03,\,0.1$ respectively, employing 3D hyper-Lagrangian resolution simulations with the {\sc gizmo}-MFM code. We extract spectral energy distributions and light curves in different frequency bands (i.e. X-ray, optical and UV) from the simulations. We find a clear two orders of magnitude drop in the X-ray flux right before merger if the disc is warm while we identify a significant increase in the UV flux regardless of the disc temperature.
 The optical flux shows clear distinctive modulations on the binary orbital period and on the cavity edge period, regardless of the disc temperature.
 We find that the presence of a cold disc can accelerate the coalescence of the binary by up to 130 seconds over the last five days of inspiral, implying a phase shift accumulation of about $π\,$radians compared to the binary evolution in vacuum. These differences are triggered by the presence of the gaseous disc and might have implications on the waveforms that can be in principle detected.
 We discuss the implications that these distinctive signatures might have for existing and upcoming time domain surveys and for multimessenger astronomy.

Hydrologic impacts of dust on snow in the Upper Colorado River Basin

description: Water availability is one of the most pressing scientific and societal issues facing the western United States. By 2060, population within the Colorado River Basin is expected to grow 19-48% relative to the 2010 population, significantly increasing the demand for water. Simultaneously, streamflow in the Colorado River is projected to decrease between 5-20%, putting further strain on an already over-allocated system. The highelevation snowpack of the Upper Colorado River Basin (UCRB) contributes the majority of runoff to the Colorado River through winter snow accumulation and springtime snowmelt. Recent studies have shown however, that dust from the Colorado Plateau shortens snowcover duration in the southeastern portion of the UCRB by 25-51 days. By accelerating snowmelt and extending the snow-free season, this impact appears to have shifted peak normalized runoff at Lee's Ferry, AZ 3-6 weeks earlier and reduced the total annual runoff of the Colorado River by 5-6% relative to the cleaner-snow conditions that existed prior to the western expansion of the United States in the mid-1800s. The agency charged with monitoring and forecasting streamflow in the UCRB is the Colorado Basin River Forecast Center (CBRFC). The CBRFC predicts snowmelt runoff using the temperature-index based SNOW-17 model that assumes an empirical relationship between temperature and snowmelt. The melt factor used in SNOW-17 is effectively a calibrated index of the relative proportions of snow surface energy balance components over the model's calibration period. If energy balance components deviate from the calibration-period mean, however, the fraction of radiation absorbed by the snowpack can also shift, influencing snowmelt timing and runoff and rendering the melt index less representative. Based on observations and in situ measurements, we know that dust deposition varies annually and spatially throughout the UCRB. The work described herein is directed at improving our understanding of the spatial and temporal variability of dust radiative forcing in snow and ultimately how that variability impacts streamflow forecasting in the UCRB.

description: This project is about detecting and imaging damage (such as cracks) in a plate by using ultrasonic waves. The waves are generated by a source (an ultrasonic transducer) that is part of a robot that can move on the plate. The waves traveling in the plate are recorded at a receiver (another ultrasonic transducer) that is also carried by the robot. The imaging method we use is Kirchhoff migration and we do a rigorous resolution study of this imaging method for two different configurations of the source/receiver pair, assuming the robot follows a straight path and that certain length scalings hold. Our results reveal that one of the setups gives images with much better resolution than the other one. Imaging on other paths is illustrated with numerical experiments. The application of this research is to aircraft structural health monitoring and is done in collaboration with Thomas Henderson [2] (School of Computing, University of Utah).

description: Understanding long-term ice dynamic response to climate change remains of the utmost importance with respect to constraining sea level rise (SLR) projections for 2100. SLR contributions from Alaska approximate those from Greenland and may be dominated by mass losses from changes in flow dynamics. But due to a lack of data on flow dynamics, projections for future mass change in Alaska only consider surface mass balance. Here we present the first regionally extensive dataset of mountain glacier flow velocities in Alaska-covering 28,022 km2 of ice. This dataset reveals that more than 50% of the mass flux in Alaska comes from only eleven key glacier systems that have high mass fluxes due to high balance velocities and are not necessarily linked to tidewater glacier retreat. In south central Alaska, we find that the rate of mass loss from tidewater calving is equivalent to 75% of the total net mass loss annually; thus surface mass balance alone is inadequate to project future statewide mass losses. Our dataset also enables a close examination of a surge (periodic acceleration) event on Bering Glacier, the largest surging glacier in the world. There, velocities exceed quiescent speeds by 18 times over two periods lasting a total of 3 years. Results suggest that downstream propagation of the surge is closely linked to the evolution of the driving stress during the surge because driving stress appears to be tied to the spatial variability of resistive stress provided by the bed. Finally, we are able to examine regional changes in wintertime flow velocities and find that wintertime flow speed is inversely correlated with summertime positive degree days. We propose that this relationship is the result of a negative feedback mechanism whereby increased meltwater production enlarges subglacial conduit systems that are more effective at discharging water from subglacial cavities. As cavities close during the fall, less remaining water reduces bed separation during winter and thus engenders slower sliding velocities. We find this mechanism exerts a secondary control on glacier surge triggering, encouraging/discouraging initiation after cold/warm summers. This mechanism could have important ice dynamic implications when forced by a changing climate. Increases in summertime temperatures could result in a gradual slowing of land terminating ice, thus providing a negative feedback (self correcting) mechanism that could slightly slow projected mass losses from land terminating glaciers.

description: The effect of affluence upon increased breast cancer incidence is a widely studied phenomenon. However, utilizing affluence at time of diagnosis may prove noninformative due to residential mobility and variable socioeconomic status (SES) through an individual's life. Examining a cohort of women born in Utah from 1945-1959, this study seeks to determine whether individual and/or area-based SES at birth is associated with female breast cancer risk in life, and to determine if the incidence of female breast cancer is spatially clustered based on residential location at birth. We utilized Cox proportional hazards (PH) models as a means of determining the impact of SES at birth and adult breast cancer incidence. To examine the potential for spatial clustering patterns at birth, space time scan statistics were run employing 1960 census tracts based on cohort members' residence at birth. Cox PH modeling found that women born into low SES families were less likely to develop breast cancer than women born into the highest SES groups (Q1 HR=0.83 95% CI: 0.72-0.97; Q2 HR=0.81 95% CI: 0.69-0.96). Spatial clustering was limited, though women born in a 2-year time period in South Salt Lake City and the Sugarhouse neighborhood of Salt Lake City exhibited significantly higher risk than their peers (RR=2.2, p-value 0.005). This study seeks to identify mechanisms linking SES at birth to adult breast cancer onset. The findings stress the importance of living and economic conditions at birth and their long-term impacts on breast cancer risk factors and incidence.

description: Multiplayer games on graphs are at the heart of theoretical descriptions of key evolutionary processes that govern vital social and natural systems. However, a comprehensive theoretical framework for solving multiplayer games with an arbitrary number of strategies on graphs is still missing. Here, we solve this by drawing an analogy with the Balls-and-Boxes problem, based on which we show that the local configuration of multiplayer games on graphs is equivalent to distributing $k$ identical co-players among $n$ distinct strategies. We use this to derive the replicator equation for any $n$-strategy multiplayer game under weak selection, which can be solved in polynomial time. As an example, we revisit the second-order free-riding problem, where costly punishment cannot truly resolve social dilemmas in a well-mixed population. Yet, in structured populations, we derive an accurate threshold for the punishment strength, beyond which punishment can either lead to the extinction of defection or transform the system into a rock-paper-scissors-like cycle. The analytical solution also qualitatively agrees with the phase diagrams that were previously obtained for non-marginal selection strengths. Our framework thus allows an exploration of any multi-strategy multiplayer game on regular graphs.

description: The part of northwest Uinta County, Wyoming, covered by this investigation, contains both igneous and sedimentary  rocks. The igneous rocks are  tuffs of late Eocene age. These  tuffs comprise the Fowkes and Bridger (?) formations (Veatch, 1907), and are  the youngest formations exposed in the area.  Particular attention is paid to the Fowkes formation in an attempt to correlate it with the Norwood tuff of northeastern Utah.  Mapped strata range in age from Lower Cretaceous to late Eocene. A major unconformity in the section spans most of Upper Cretaceous time. A second unconformity represents the Paleocene-Eocene transition time.  Structural features include a major zone of normal faults, part of a broad syncline, a minor anticlinal fold, and landslide features. Most faults trend northerly, forming a parallel pattern.  Economic interests in the area center around oil, coal, clay, and high­ way construction materials. No economic production of oil is noted at the time of this writing (1961).
Kalashnikov enculturation: The Soviet contribution to small arms proliferation and the disintegration of the non-state threshold

description: The purpose of this paper is to closely examine the legacy of the policies and actions taken by the Soviet Union during the Cold War in order to determine its contributions to current levels of small arms and light weapons (SALW) proliferation around the globe. This examination confirms as reality the perception of the Soviet Union as the primary propagator of indiscriminate small arms proliferation in the post-Cold War era. As such, the Soviet Union was a chief contributor to the current situation of global insecurity perpetuated by the creation of extensively armed and violent societies known commonly as Kalashnikov Cultures. In examining the impact of Soviet policies on SALW proliferation, this paper utilizes the concept of the "Non-State Threshold" at which, when intact, small arms and light weapons are effectively segregated between legitimate state and illegitimate nonstate actors, and when breached, indiscriminate spread occurs. The Non-State Threshold will be applied to the years during and immediately following the Cold War to determine under which conditions indiscriminate SALW proliferation occurred, and to facilitate a clearer understanding of how Soviet policies and actions allowed for the permeation of the Threshold by increasing the availability, ease of acquisition, and appeal of SALW to non-state actors and illegitimate groups. This paper demonstrates how the legacy of Soviet policies has facilitated the creation of dangerously armed, rogue societies, supporting the claim that it is the actions of the Soviet Union specifically that have disproportionately contributed to the creation of Kalashnikov Cultures.
