description: We construct harmonic Riemannian submersions that are retractions from symmetric spaces of noncompact type onto their rank-one totally geodesic subspaces. Among the consequences, we prove the existence of a non-constant, globally defined complex-valued harmonic morphism from the Riemannian symmetric space associated to a split real semisimple Lie group. This completes an affirmative proof of a conjecture of Gudmundsson.

description: Ensuring adequate wireless coverage in upcoming communication technologies such as 6G is expected to be challenging. This is because user demands of higher datarate require an increase in carrier frequencies, which in turn reduce the diffraction effects (and hence coverage) in complex multipath environments. Intelligent reflecting surfaces have been proposed as a way of restoring coverage by adaptively reflecting incoming electromagnetic waves in desired directions. This is accomplished by judiciously adding extra phases at different points on the surface. In practice, these extra phases are only available in discrete quantities due to hardware constraints. Computing these extra phases is computationally challenging when they can only be picked from a discrete distribution, and existing approaches for solving this problem were either heuristic or based on evolutionary algorithms. We solve this problem by proposing fast algorithms with provably optimal solutions. Our algorithms have linear complexity, and are presented with rigorous proofs for their optimality. We show that the proposed algorithms exhibit better performance. We analyze situations when unwanted grating lobes arise in the radiation pattern, and discuss mitigation strategies, such as the use of triangular lattices and prephasing techniques, to eliminate them. We also demonstrate how our algorithms can leverage these techniques to deliver optimum beamforming solutions.

Consent and loyalty as bases of legitimate political authority
Creators: name: Allen, JG
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis examines consent as the purported criterion of legitimate political authority and basis of political obligation in modern liberal democracies. Liberal consent theory posits autonomy as the basis of legitimate political authority, in as much as consent is an act of the individual's free, autonomous will. Voluntary subjection to political power transforms it into genuine political authority. On this view, consent is the mechanism by which autonomy is protected in social interactions generally, including those of a political nature. Only those political relationships that are based on genuine, autonomy-protecting consent are legitimate: only they can give rise to legitimate political authority over others and only they can give rise to real obligations to obey any rule set over us by another.

description: Following Kamionkowski (2008), a quadratic estimator of the rotation of the plane of polarization of the CMB is constructed. This statistic can estimate a spatially varying rotation angle. We use this estimator to quantify the prospects of detecting such a rotation field with forthcoming experiments. For PLANCK and CMBPol we find that the estimator containing the product of the E and B components of the polarization field is the most sensitive. The variance of this EB estimator, N(L) is roughly independent of the multipole L, and is only weakly dependent on the instrumental beam. For FWHM of the beam size ~ 5'-50', and instrument noise $Δ_p ~ 5-50 uK-arcmin, the scaling of variance N(L) can be fitted by a power law N(L)=3.3 x 10^{-7} Δ^2_p (FWHM)^{1.3} sq-deg. For small instrumental noise Δ_p \leq 5 uK-arcmin, the lensing B-modes become important, saturating the variance to ~10^{-6} sq-deg even for an ideal experiment. Upcoming experiments like PLANCK will be able to detect a power spectrum of the rotation angle, C^{αα}(L), as small as 0.01 sq-deg, while futuristic experiment like CMBPol will be able to detect rotation angle power spectrum as small as 2.5 x 10^{-5} sq-deg. We discuss the implications of such constraints, both for the various physical effects that can rotate the polarization as photons travel from the last scattering surface as well as for constraints on instrumental systematics that can also lead to a spurious rotation signal. Rotation of the CMB polarization generates B-modes which will act as contamination for the primordial B-modes detection. We discuss an application of our estimator to de-rotate the CMB to increase the sensitivity for the primordial B-modes.

description: The effects of design and thicknesses of different optically transparent p-current spreading layers [short-period superlattice, superlattice (SL), and bulk p- (Formula presented.)] as well as the type and thickness of the p-GaN cap layer on the electrical and optical characteristics of 310 nm ultraviolet light-emitting diodes (LEDs) are investigated. Scanning transmission electron microscopy measurements display self-organized composition variations in the nonpseudomorphically grown SLs, reducing the effect of increased hole injection efficiency of a SL. In addition, the effect leads to an increased operation voltage. In contrast, the bulk p-AlGaN layer has a uniform composition and the corresponding LEDs show only a slightly lower output power along with a lower operating voltage. If the thickness of the p-AlGaN bulk layer in the LED is reduced from 150 nm to 50 nm, the output power increases and the operating voltage decreases. Finally, LEDs with a nonuniform (Formula presented.) -GaN cap layer from a 3D island-like growth mode feature the highest output power and operating voltage. In contrast, the output power and operating voltage of LEDs with a smooth and closed cap depend on the thickness of (Formula presented.) -GaN. The highest output power and lowest operating voltage are achieved for LEDs with the thinnest (Formula presented.) -GaN cap. © 2020 The Authors. Published by Wiley-VCH GmbH
title: Estimating the Effectiveness of a Seasonal Gas Tax for Controlling Episodic PM2.5 Concentrations in Cache County, Utah

Publisher: name: Utah State University
Year: 2014

description: For several years, residents of Cache County, Utah have suffered from the recurrence of what has come to be known as the winter-inversion, or “red-air-day” season. Each year during this season – which occurs primarily in the months of December, January, and February – particulate matter concentrations measuring two and half micrometers or less (commonly known as PM2.5) rise and languish (for periods of days or even weeks) above federally mandated standards, causing extensive harm to community health and confounding what have thus far been the relatively tepid control efforts undertaken by local and state policymakers.
Through time-series regression modeling, we establish a statistical relationship between PM2.5 concentrations and vehicle use in Cache County, and further calculate a gas-price elasticity for the region. Next, we analyze the benefits and costs associated with a potential seasonal gas tax which, if set appropriately and enforced effectively, could decrease vehicle use and thereby lower health costs through concomitant decreases in PM2.5 concentrations. Specifically, we find a relatively strong positive relationship between percentage of vehicle trips reduced and associated reductions in PM2.5concentrations, and a gas price elasticity of approximately -0.31 in what we call a “high price variability environment.”
Based upon these results, benefit-cost analysis suggests a potentially positive social net benefit for Cache County associated with imposing a seasonal gas tax to reduce PM2.5 concentrations during the winter-inversion season. Our benefit-cost analysis, which uses quantitative estimation techniques on both sides of the ledger, yields a first-of-its-kind social net benefit estimate for controlling elevated PM2.5 concentrations in Cache County through the imposition of a seasonal gas tax.

Protein and energy nutrition of brook trout, Salvelinus fontinalis (Mitchill, 1814)
Creators: name: Amin, Md.N
Publisher: name: University Of Tasmania
Year: 2023

description: Temperature affects the growth and nutrient utilisation of fish. Diet formulations to the specific protein and energy requirements of brook trout, Salvelinus fontinalis, particularly at higher temperatures will be required for sustainable production. The optimum temperature for brook trout growth is 15¬¨‚àûC, however, in Australia, summer water temperature is often elevated to about 19¬¨‚àûC. Considering this, protein and energy requirements of brook trout were determined at 15¬¨‚àûC and 19¬¨‚àûC. Using a dose-response model, the digestible dietary protein requirement of brook trout for optimum growth rate was 44% and 40% at 15¬¨‚àûC and 19¬¨‚àûC, and for optimum protein efficiency was 39% and 35% at 15¬¨‚àûC and 19¬¨‚àûC, respectively. Using factorial modelling, the maintenance requirements for digestible protein were 0.11 gDP¬¨‚àëkg-0.70¬¨‚àëd-1 (15¬¨‚àûC) and 0.22 gDP¬¨‚àëkg- 0.70¬¨‚àëd-1 (19¬¨‚àûC) and for energy were 29.87kJDE¬¨‚àëkg-0.80¬¨‚àëd-1 (15¬¨‚àûC) and 36.66 kJDE¬¨‚àëkg-0.80¬¨‚àëd- 1 (19¬¨‚àûC). Specific growth rate, feed utilisation indices and apparent digestibility of nutrients were significantly higher at 15¬¨‚àûC. Higher levels of gelatinised carbohydrate increased protein efficiency and although liver glycogen storage was increased, it did not cause any pathological symptoms in the liver or intestine. The activity of glycolytic enzyme (PK) in the liver was increased with increasing levels of gelatinised carbohydrate and with higher temperature. Liver lipogenic enzyme (G6PDH) activity was neither affected by temperature nor dietary gelatinised carbohydrate level. Brook trout used gelatinised maize starch effectively for energy at 26%, and at least 13% dietary gelatinised carbohydrate should be added to brook trout feeds to reduce protein catabolism (GDH activity). The effect of replacing energy from lipid with carbohydrate on growth performance, nutrient utilisation and digestibility of brook trout was evaluated at 15¬¨‚àûC and 19¬¨‚àûC. Energy source had no effect on growth, protein utilisation and feed utilisation. At both temperatures, 26% carbohydrate improved the apparent digestibility of dry matter (ADDM), gross energy (ADGE) and energy from carbohydrate (ADCHO-E). Higher levels of gelatinised carbohydrate increased the activity of ˜í¬±-amylase; however, at 19¬¨‚àûC activity was lower than at 15¬¨‚àûC. There is great potential for high levels of gelatinised maize starch as an alternative energy source in brook trout diets to replace protein and lipid without compromising the growth or the function of liver and intestine. While growth was better at 15¬¨‚àûC, carbohydrate effectively met the increased energy requirements at 19¬¨‚àûC. This study has defined digestible protein and energy requirements for brook trout which can be applied to commercial feeds for production under optimum and challenging summer conditions.
Rectangular bar and no-bar finite elements for three dimensional stress analysis

Publisher: name: University of British Columbia
Year: 2011

description: A three dimensional bar cell in the form of a rectangular parallelopiped capable of imitating the action of elastic bodies of any value of Poisson's ratio is devised for three dimensional stress analysis by the finite element method and the stiffness matrix of the cell is derived. Furthermore a rectangular no-bar cell is also formed by extending the idea of linear displacement functions from two dimensional to three dimensional cases and the stiffness matrices of this cell are derived both by the method of virtual work and by statics. Both these types of cells are used to solve three dimensional problems and the results in the form of displacements and stresses are compared with the exact elasticity solutions using different mesh sizes and different values of Poisson's ratio. The stresses found by the Finite element method are calculated in two ways: by the Joint displacement method (using two different procedures) and by the Nodal force method and the quality of solution obtained by these methods is compared. Finally the same examples are also analysed by using the framework models proposed by "Yettram and Robbins". ⁽⁶⁾* The results obtained by these several methods were good, with the ones corresponding to the proposed bar model being consistently the best of the three. The stresses found by both the Joint displacement and the nodal force methods were found comparable in quality. * Numbers signify the references, listed in Bibliography.

description: The decadal evolution of Arctic and Antarctic sea ice following strong volcanic eruptions is investigated in four climate simulation ensembles performed with the COSMOS-Mill version of the Max Planck Institute Earth System Model. The ensembles differ in the magnitude of the imposed volcanic perturbations, with sizes representative of historical tropical eruptions (1991 Pinatubo and 1815 Tambora) and of tropical and extra-tropical "supervolcano" eruptions. A post-eruption Arctic sea-ice expansion is robustly detected in all ensembles, while Antarctic sea ice responds only to supervolcano eruptions, undergoing an initial short-lived expansion and a subsequent prolonged contraction phase. Strong volcanic forcing therefore emerges as a potential source of inter-hemispheric interannual-to-decadal climate variability, although the inter-hemispheric signature is weak in the case of eruptions comparable to historical eruptions. The post-eruption inter-hemispheric decadal asymmetry in sea ice is interpreted as a consequence mainly of the different exposure of Arctic and Antarctic regional climates to induced meridional heat transport changes and of dominating local feedbacks that set in within the Antarctic region. Supervolcano experiments help to clarify differences in simulated hemispheric internal dynamics related to imposed negative net radiative imbalances, including the relative importance of the thermal and dynamical components of the sea-ice response. Supervolcano experiments could therefore serve the assessment of climate models' behavior under strong external forcing conditions and, consequently, favor advancements in our understanding of simulated sea-ice dynamics.

description: A new complex network model is proposed which is founded on growth with new connections being established proportionally to the current dynamical activity of each node, which can be understood as a generalization of the Barabasi-Albert static model. By using several topological measurements, as well as optimal multivariate methods (canonical analysis and maximum likelihood decision), we show that this new model provides, among several other theoretical types of networks including Watts-Strogatz small-world networks, the greatest compatibility with three real-world cortical networks.

description: Non-native invasive plant species can often have negative effects on native ecosystems, such as altered nutrient cycling, decreased habitat for wildlife, and outcompeting native plants. Around the Great Salt Lake (GSL), Utah, the invasive wetland grass Phragmites australis has become abundant in wetlands around the lake. Phragmites is replacing many native wetland plants provide important waterfowl habitat around the GSL. For successful management of Phragmites in GSL wetlands, it is important to know the current distribution of Phragmites, as well as areas that might be vulnerable to future invasion by Phragmites. To do this, we used multispectral aerial imagery to map the current distribution of Phragmites. We then created a model that statistically related the Phragmites distribution data to a suite of environmental predictor variables such as salinity, proximity to nutrient sources, or proximity to roads. Results from our model suggest that Phragmites is more likely to be found in wetland areas close to point sources of pollution, with lower elevations with prolonged inundation, and with moderate salinities. We used these results to identify areas around GSL that might be vulnerable to future invasion. Results from our study will assist wetlands managers in prioritizing areas for Phragmites monitoring and control by closely monitoring areas of prime Phragmites habitat.

description: The current institutional and governance system of displacement has become much more complex with the inclusion of ever more actors. But it still leaves open multiple gaps of protection. To close these protection gaps and to more effectively address protracted displacement, it requires a better collaboration and coordination between international, regional and domestic stakeholders, a long-term development rather than a short-term humanitarian approach and sincere recognition of displaced people’s rights and their mobility needs. TRAFIG Practice Note No. 3 analyses the different regimes governing displacement and stresses that it is crucial to enable displaced people to access rights as the "Recognition of refugees’ rights has the potential to strengthen their contribution to the social and economic life of the country of reception and directly addresses the protracted nature of their displacement".

Plane stress analysis with isosceles trapizoidal bar cells
Creators: name: Charania, Hajimohammed Gulamhussin
Publisher: name: University of British Columbia
Year: 2011

description: A bar cell in the form of an isosceles trapezoid suitable for solution of two dimensional problems is introduced involving two new concepts, one that of overlapping bars and the other of a variable angle parameter. Based on the Identity of corner displacements of the cell and a similarly shaped piece of plate in conditions of uniform stress, expressions for the bar areas are derived in terms of Poisson's ratio, the geometry of the cell and a variable angle parameter. The stiffness matrix of the cell is derived further by combining different displacement modes. Two methods of calculating stresses, one by the nodal displacements and the other by the nodal force concentrations, are described. Two examples involving a rectangular plate and a partial sector of a circular plate illustrate the application of the finite element method using trapezoidal bar as well as no-bar cells and their results are compared with the exact elasticity solution.

description: We report a combined study of the Nernst coefficient (v), Hall effect and thermoelectric power of CaFe2As2 and CaFe1.92Co0.08As2 single crystals. The absolute value of v in both samples is enhanced, probably due to ambipolar flow of electron- and hole-like quasiparticles. The onset of spin-density-wave order in CaFe2As2 causes further rapid rise of the Nernst coefficient. On the contrary, in the CaFe1.92Co0.08As2 crystal we do not see any feature of v(T), which could be clearly associated with SDW fluctuations. In this Co-doped sample there is also no noticeable increase in of v in the vicinity of superconducting transition, despite the expectation of such due to vortex movement.

title: Graphics Processing Unit-Based Computer-Aided Design Algorithms for Electronic Design Automation
Creators: name: Han, Yiding
Publisher: name: Utah State University
Year: 2014

description: The electronic design automation (EDA) tools are a specific set of software that play important roles in modern integrated circuit (IC) design. These software automate the design processes of IC with various stages. Among these stages, two important EDA design tools are the focus of this research: floorplanning and global routing. Specifically, the goal of this study is to parallelize these two tools such that their execution time can be significantly shortened on modern multi-core and graphics processing unit (GPU) architectures. The GPU hardware is a massively parallel architecture, enabling thousands of independent threads to execute concurrently. Although a small set of EDA tools can benefit from using GPU to accelerate their speed, most algorithms in this field are designed with the single-core paradigm in mind. The floorplanning and global routing algorithms are among the latter, and difficult to render any speedup on the GPU due to their inherent sequential nature.
This work parallelizes the floorplanning and global routing algorithm through a novel approach and results in significant speedups for both tools implemented on the GPU hardware. Specifically, with a complete overhaul of solution space and design space exploration, a GPU-based floorplanning algorithm is able to render 4-166X speedup, while achieving similar or improved solutions compared with the sequential algorithm. The GPU-based global routing algorithm is shown to achieve significant speedup against existing state-of-the-art routers, while delivering competitive solution quality. Importantly, this parallel model for global routing renders a stable solution that is independent from the level of parallelism. In summary, this research has shown that through a design paradigm overhaul, sequential algorithms can also benefit from the massively parallel architecture. The findings of this study have a positive impact on the efficiency and design quality of modern EDA design flow.

In the shadow of Van Diemen's Land : a visual investigation into phenomenological, ontological and experiential representations of places and their history
Creators: name: Bird, DM
Publisher: name: University Of Tasmania
Year: 2023

description: This project investigates modes of representing the experience of a historically informed experience of place, through firsthand engagement with the Tasmanian Central Plateau by a subjective viewer. It explores the potential of printmaking practices of large-scale multi-plate intaglio engraving to represent this engagement, using the culturally charged symbolism of the endangered Miena Cider Gum trees of the Tasmanian Central Plateau. The project's context lies in the expanding theoretical literature around place, the historical record of the Tasmanian Central Plateau and associated Indigenous/European history surrounding the Cider Gum tree, Eucalyptus gunnii, and a local and international artistic discourse which includes the work of Mike Parr, Raymond Arnold, Michael Schlitz, and Orit Hofshi. The theoretical discussion of the project is woven through concepts expressed in the writings of, among others, Peter Hay, Simon Schama, Jeff Malpas, Maria Tumarkin, Edward Relph, Roslyn Haynes and James Boyce, along with an examination of the historical documentation of the Cider Gum tree, particularly within that of the journals of George Augustus Robinson. The project concludes that the connection between people and place is inherently interwoven, underpinned by historical knowledge, and fundamental to cultural identity, and seeks to represent this engagement through poetic expression of a distinctly Vandiemonian subjectivity. This research has produced a body of artwork born out of subjective personal experience, expressed in a contemporary printbased installation, that makes use of the multiple and the layering possibilities of the medium to explore through elegy, analogy, and anthropomorphic form, notions of cultural and experiential saturation in place.
I-V curve signatures of nonequilibrium-driven band gap collapse in magnetically ordered zigzag graphene nanoribbon two-terminal devices

description: Motivated by the very recent fabrication of sub-10-nm-wide semiconducting graphene nanoribbons [X. Li et al., Science 319, 1229 (2008)], whose band gaps extracted from transport measurements were fitted to density functional theory predictions for magnetic ordering along zigzag edges that is responsible for the insulating ground state, we compute current-voltage (I-V) characteristics of finite-length zigzag graphene nanoribbons (ZGNR) attached to metallic contacts. The transport properties of such devices, at source-drain bias voltages beyond the linear response regime, are obtained using the nonequilibrium Green function formalism combined with the mean-field version of the Hubbard model fitted to reproduce the local spin density approximation description of magnetic ordering. Our results indicate that magnetic ordering and the corresponding band gap in ZGNR can be completely eliminated by passing large enough DC current through it. The threshold voltage increases with the ZGNR length (e.g., reaching $\approx 0.8$ V for $\simeq 13$ nm long ZGNR) which provides possible explanation of why the recent experiments [Wang et al., Phys. Rev. Lett. 100, 206803 (2008)] on $\sim 100$ nm long GNR field-effect transistors with bias voltage less than 1 V did not detect the I-V curve signatures of the band gap collapse. Thus, observation of predicted abrupt jump in the I-V curve of two-terminal devices with short ZGNR channel and transparent contacts will confirm its zigzag edge magnetic ordering via all-electrical measurements, as well as a current-flow-driven magnetic-insulator--nonmagnetic-metal nonequilibrium phase transition.

The latter is more amenable to a fully quantum mechanical analysis. We formulate and solve the problem whereby a spin current interacts with a ferromagnetic Heisenberg spin chain, to eventually reverse the magnetization of the chain. Spin-flips are accomplished through both elastic and inelastic scattering. A consequence of the inelastic scattering channel, when it is no longer energetically possible, is the occurrence of a new entity: a non-equilibrium bound state (NEBS), which is an emergent property of the coupled local plus itinerant spin system. For certain definite parameter values the itinerant spin lingers near the local spins for some time, before eventually leaking out as an outwardly diffusing state. This phenomenon results in novel spin-flip dynamics and filtering properties for this type of system.

description: Groundwater levels over northern Utah have undergone a declining trend since the 1960’s. This trend has made apparent the need to understand the relationship between climate and groundwater resources. Such necessary information is already in dire need in places such as California. At the close of 2013, California had experienced its driest year in recorded history, with severe drought continuing for the foreseeable future. Utah is the second driest state in the U.S., and therefore has been paying close attention to California’s current water crises. Water resource projections may prove to be one of the most vital pieces of information toward securing adequate water for those who are currently enduring such water shortages.
In order to accomplish the initial research necessary for developing a fundable proposal, we requested support from the Utah State University Research Catalyst Grant to (a) evaluate a state-of-the-art climate model (its ability to assess groundwater) against statewide groundwater wells and operational groundwater models, (b) reduce climate model uncertainties, (c) conduct a study in the form of observational well site evaluations, and (d) develop strategies to effectively disseminate information on Utah’s future groundwater budget to water managers and policy makers. This research is now fully funded externally by the Bureau of Reclamation.

description: Hypersubstitutions are mappings which map operation symbols to terms. Terms can be visualized by trees. Hypersubstitutions can be extended to mappings defined on sets of trees. The nodes of the trees, describing terms, are labelled by operation symbols and by colors, i.e. certain positive integers. We are interested in mappings which map differently colored operation symbols to different terms. In this paper we extend the theory of hypersubstitutions and solid varieties to multi-hypersubstitutions and colored solid varieties. We develop the interconnections between such colored terms and multi-hypersubstitutions and the equational theory of Universal Algebra. The collection of all varieties of a given type forms a complete lattice which is very complex and difficult to study; multi-hypersubstitutions and colored solid varieties offer a new method to study complete sublattices of this lattice.

title: Kigali Charity School Analyzed Through an Implementation Science Framework
Creators: name: Fronk, Alexander T.
Publisher: name: Utah State University
Year: 2014

description: Implementation science is a relatively new field focused on ensuring that programs are planned well and then delivered as planned. This thesis describes the implementation process for a nursery-level charity school in Kigali, Rwanda, focusing on the facilitators and difficulties encountered in establishing this school.
The research process consisted of interviewing 13 individuals that are a part of the school in question. The researcher transcribed the interviews using an implementation science framework and found trends in their statements that shed light on the establishment of the school. With the help of three coders, the researcher assessed their comments for evidence of helps and hindrances through the implementation process. This thesis presents the results and the implications for implementation science. It will provide valuable information for those wishing to start and maintain grassroots, charitable programs for children in the developing world.
title: Obsidian Toolstone Conveyance: Southern Idaho Forager Mobility

description: The purpose of this study is to understand how prehistoric people moved around the landscape and used major stone tool resources throughout the last 10,000 yr. B.P. in southern Idaho. Similar research has been reported in the Great Basin and western Wyoming and this study continues to fill the map with data about how large regions of the western United States were used prehistorically. This study specifically examined whether or not prehistoric mobility changed according to wet and dry climatic shifts. Based on these shifts archaeologists expect the regions people used to expand or shrink using an economic model of decision-making when foragers were confronted with the choice to stay in one resource area or move to another while pursuing plants and animals for food. To measure this decision prehistorically, obsidian projectile points and tools left behind throughout time were analyzed to determine where the stone originated geologically, a concept known as conveyance. The data were gathered from many regional studies and new sourcing of 139 artifacts from southeastern Idaho regional collections and excavations at the Fox Site near Thatcher, Idaho. In the compiled dataset are 4,440 artifacts from 640 archaeological sites in southern Idaho that originate from 37 obsidian sources.
Analysis of this dataset grouped archaeology sites based on the percentage of different obsidian sources used, creating conveyance zone sets that were encompassed by statistically created ovals in mapping software. Four trans-Holocene conveyance zones are proposed and described: the Malad Conveyance Zone (MCZ), Timber Butte Conveyance Zone (TBCZ), Big Southern Butte Conveyance Zone (BSBCZ), and Snake River Conveyance Zone (SRCZ). These zones are then separated into four wet or dry climate periods and changes in mobility are compared to the economic decision model. Overall the MCZ and TBCZ both met the expectations of the model, while the BSBCZ and SRCZ did not. Another test of the data reveals that the number of obsidian sources used and the evenness of their use is not correlated with conveyance zone size, which helps confirm that these zones reproduce prehistoric behavior and are not a statistical product of the availability of obsidian in a region.
The conveyance zones described in this study are comparable in size to those proposed in neighboring regions. Research also finds that southern Idaho conveyance zones were firmly established in the Early Holocene and shows that conveyance zones can be created from large datasets in a statistically robust manner and enable researchers to look at changes in forager mobility across large spatial and temporal scales. Expectations for forager mobility are partially supported by the variability wet and dry climate during the last 10,000 years B.P.

description: We study, within an effective field theory framework, $O(E^{2}/\Mpl^{2})$ Planck-scale suppressed Lorentz invariance violation (LV) effects in the neutrino sector, whose size we parameterize by a dimensionless parameter $η_ν$. We find deviations from predictions of Lorentz invariant physics in the cosmogenic neutrino spectrum. For positive O(1) coefficients no neutrino will survive above $10^{19} \eV$. The existence of this cutoff generates a bump in the neutrino spectrum at energies of $10^{17} \eV$. Although at present no constraint can be cast, as current experiments do not have enough sensitivity to detect ultra-high-energy neutrinos, we show that experiments in construction or being planned have the potential to cast limits as strong as $η_ν \lesssim 10^{-4}$ on the neutrino LV parameter, depending on how LV is distributed among neutrino mass states. Constraints on $η_ν < 0$ can in principle be obtained with this strategy, but they require a more detailed modeling of how LV affects the neutrino sector.

Health informatics discourses and the use of personal health information : which piper, which tune, who pays?
Creators: name: Whetton, S
Publisher: name: University Of Tasmania
Year: 2023

description: This study poses the question 'health informatics: which piper, which tune, and who pays?' to explore issues of power and influence in the use of personal health information in Australia. It draws on the work of Michel Foucault to explore how understandings about the use of personal health information facilitate its expanding use. Of particular interest is the way in which the health informatics community influences these understandings. The study begins with the argument that increasing use of personal health information for secondary purposes is symptomatic of a broader societal trend of expanding information gathering and surveillance practices. It further argues that many of these practices move beyond accepted monitoring to become surveillance which may result in discrimination, disadvantage or social exclusion. The discipline of surveillance studies provides the context for exploring these arguments. Surveillance scholars draw on a range of sociological theories to explore and explain expanding uses of personal information in contemporary society. However, surveillance literature focuses primarily on the processes and consequences of these activities rather than on explaining how or why they occur. Michel Foucault's conceptualisation of information gathering and surveillance as part of a network of modern disciplinary power provides an explanation of the how and why. Therefore, this study locates its analysis within the context of contemporary surveillance studies while utilising Michel Foucault's arguments about the relationship between modern power, knowledge and discourse. This enables the study to explore links between the views of the health informatics community, the construct of the Australian privacy framework and systemic expansion of information gathering practices. The study reviewed legislation and associated documents related to Australia's privacy framework. It identified a privacy/public interest dichotomy as the dominant approach to managing use of personal information and argues that this construct facilitates expanded uses of personal information on the basis of public interest. A Foucauldian influenced discourse analysis of the academic discipline of health informatics identified six discourses, all of which constructed information management issues in terms of this privacy/public interest balance. The study concludes that the health informatics community is a claim-making site with the potential to shape understandings about the use of personal health information in Australia. However, aspirational goals of the discipline work to discourage critical analyses of the privacy/public interest dichotomy. This creates the potential for the health informatics community, either wittingly or unwittingly, to support expanding use of personal information for activities that may result in increased monitoring and control of individuals, groups and the community as a whole.
