description: In contrast to the long-known fact that spin-flip hot spots, i.e., special \vc{k}-points on the Fermi surface showing a high spin-mixing parameter, do not occur in the bulk of monovalent (noble and alkali) metals, we found them on the surface Brillouin-zone boundary of ultrathin films of these metals. Density-functional calculations within the Korringa-Kohn-Rostoker Green function method for ultrathin (001) oriented Cu, Ag, and Au films of 10-layer thickness show that the region around the hot spots can have a substantial contribution, e.g.\ 52\% in Au(001), to the integrated spin-mixing parameter, that could lead to a significant enhancement of the spin-relaxation rate or spin-Hall angle in thin films. Owing to the appearance of spin-flip hot-spots, a large anisotropy of the Elliott-Yafet parameter [50\% for Au(001)] is also found in these systems. The findings are important for spintronics applications in which noble-metals are frequently used and in which the dimensionality of the sample is reduced.

description: A high-temperature proton exchange membrane fuel cell (HT-PEMFC) conventionally uses a planar design with carbon-based substrates as the gas diffusion layer (GDL) materials. However, the metal-based substrates allow for alternative designs. In this study, the applicability of porous thin-walled tubular elements made of 316L stainless steel as the anode GDL in a multi-layer tubular HT-PEMFC was investigated. The anode GDLs were fabricated via powder bed fusion using a laser beam (PBF-LB) process with defined porosities (14% and 16%). The morphology of the porous elements was compared using scanning electron microscopy (SEM) micrographs. The influence of the porosity on the fuel cell performance was evaluated through electrochemical characterization and a short-term stability test (45 h) in a commercial test station operated at 160 °C and ambient pressure, using hydrogen as the fuel and air as the oxidant. The results showed that the fuel cell manufactured upon the anode GDL with a porosity of 16% had a higher performance with a peak power density of 329.25 W/m² after 5 h of operation at 125.52 A/m² and a voltage degradation rate of 0.511 mV/h over the stability test period. Moreover, this work indicates that additive manufacturing could be a useful tool for further fuel cell development.
Hotel Room Rate and Availability Parity Across Electronic Distribution Channels

Publisher: name: University of Nevada, Las Vegas
Year: 2011

description: This is an exploratory research paper looking at the parity of hotel room rates and hotel room availability across electronic distribution channels. The fulfillment of the best rate guarantee of hotels was also analyzed. The study surveyed 40 hotels in Singapore, covering 4 hotel segments, luxury, upscale, mid-market and budget with data collected over 5 dates. The results were analyzed across segments and dates of collection and it was found that neither rate nor room availability parity existed across all the hotels surveyed. In addition, majority of the hotels were unable to fulfill the best rate guarantee. Reasons for why the disparities occurred are discussed and include technological incapability, problems with control of distribution channels and relationships between hotel operators and online intermediaries. Solutions for dealing with these challenges are provided and discussed.

description: The structure of sexual contacts, its contacts network and its temporal interactions, play an important role in the spread of sexually transmitted infections. Unfortunately, that kind of data is very hard to obtain. One of the few exceptions is the "Romantic network" which is a complete structure of a real sexual network of a high school. In terms of topology, unlike other sexual networks classified as scale-free network. Regarding the temporal structure, several studies indicate that relationship timing can have effects on diffusion through networks, as relationship order determines transmission routes.With the aim to check if the particular structure, static and dynamic, of the Romantic network is determinant for the propagation of an STI in it, we perform simulations in two scenarios: the static network where all contacts are available and the dynamic case where contacts evolve in time. In the static case, we compare the epidemic results in the Romantic network with some paradigmatic topologies. We further study the behavior of the epidemic on the Romantic network in response to the effect of any individual, belonging to the network, having a contact with an external infected subject, the influence of the degree of the initial infected, and the effect of the variability of contacts per unit time. We also consider the dynamics of formation of pairs in and we study the propagation of the diseases in this dynamic scenario. Our results suggest that while the Romantic network can not be labeled as a Watts-Strogatz network, it is, regarding the propagation of an STI, very close to one with high disorder. Our simulations confirm that relationship timing affects, but strongly lowering, the final outbreak size. Besides, shows a clear correlation between the average degree and the outbreak size over time.

Year: 2012

description: Alfvenic waves are thought to play an important role in coronal heating and solar wind acceleration. Here we investigate the dissipation of such waves due to phase mixing at the presence of shear flow and field in the stratified atmosphere of solar spicules. The initial flow is assumed to be directed along spicule axis and to vary linearly in the x direction and the equilibrium magnetic field is taken 2-dimensional and divergence-free. It is determined that the shear flow and field can fasten the damping of standing Alfven waves. In spite of propagating Alfven waves, standing Alfven waves in Solar spicules dissipate in a few periods. As height increases, the perturbed velocity amplitude does increase in contrast to the behavior of perturbed magnetic field. Moreover, it should be emphasized that the stratification due to gravity, shear flow and field are the facts that should be considered in MHD models in spicules.

Dressing Indian: Appropriation, Identity, and American Design, 1940-1968

description: This thesis examines the ways the American fashion industry and fashion publications appropriated aspects of Indian cultures as marketing tools from 1940 to 1968 and the ways representations stereotypes created through fashion outlets denoted American and individual, rather than Native, identity. Representational stereotypes created at the turn of the twentieth century provided fashion merchandisers and sellers with a home-grown marketing scheme, while the development of an American fashion industry based on mass-produced, ready-to-wear sportswear led to nation-wide dissemination and use of "Indian" colors, patterns, and designs.
Differential Impacts of Water Privatization in Sub-Saharan Africa
Creators: name: Varma, Asha
Publisher: name: University of Chicago
Year: 2021

description: Countries in Africa have historically struggled with access to safe water. Over the past three decades, the World Bank has promoted the privatization of water systems through contracts with foreign companies as the solution to the water crisis. However, only a handful of privatization efforts in Africa have succeeded, with most governments taking back control of their water supplies after only a few years. Furthermore, recent evidence suggests that expanded water access resulting from privatization only occurs in wealthier communities, however this has not yet been confirmed. This thesis examines the relationship between functional water access points in Tanzania, Ghana, Mozambique, and Nigeria and the income levels of the neighborhoods in which they are located, analyzing how this relationship changes before and after privatization. This quantitative approach was accompanied by a qualitative analysis of the political, economic, and geographical features of each country. When combined, these two complementary avenues of analysis demonstrate that privatization did not significantly increase water access but there was insufficient evidence to make definitive conclusions about privatization’s effect on inequalities. This thesis argues that certain models of privatization should not be promoted as primary solutions to water access because they do not appear to increase water access. Furthermore, it demonstrates the inefficacy of a ‘one-size-fits-all’ approach to expanding water access and indicates the need for solutions that are adapted to local situations.
Estimation of Travel Time Based on Vehicle-Tracking Models

Publisher: name: University of Nevada, Las Vegas
Year: 2013

description: In this thesis we study the travel time problem based on the known traffic density model. Using the conservation law, we model the travel time function by a boundary value problem of a non homogeneous linear hyperbolic equation. The equation is transformed into an initial value hyperbolic equation, and the well-posedness of the problem is discussed. The mathematical analysis for both density and travel problems are given. We also derive the analytic solutions for several special cases of traffic density. Numerical schemes are proposed for solving for travel time problem. Several numerical examples are presented and error analysis on the solutions obtained is performed to illustrate the rates of convergence of the numerical schemes.

description: We consider the Hodge Laplacian on manifolds with incomplete edge singularities, with infinite dimensional von Neumann spaces and intricate elliptic boundary value theory. We single out a class of its algebraic self-adjoint extensions. Our microlocal heat kernel construction for algebraic boundary conditions is guided by the method of signaling solutions by Mooers, though crucial arguments in the conical case obviously do not carry over to the setup of edges. We then establish the heat kernel asymptotics for the algebraic extensions of the Hodge operator on edges, and elaborate on the exotic phenomena in the heat trace asymptotics which appear in case of a non-Friedrichs extension.

Performance Comparison of Design-Build and Construction Manager/General Contractor Highway Projects
Creators: name: Shakya, Binita
Publisher: name: University of Nevada, Las Vegas
Year: 2013

description: Researchers have conducted numerous studies comparing project performance of design-bid-build (DBB) and design-build (DB) highway projects. However, little research has been done to compare the performance of DB and construction manager/general contractor (CM/GC) highway projects. Therefore, an exploratory study was conducted to compare the performance of 55 DB and 34 CM/GC highway projects from various States Departments of Transportation (DOTs) in terms of cost, change orders, and construction intensity. The results showed that contract award cost growth was significantly lower in DB projects than in CM/GC projects. In contrast to this, the total cost growth of DB projects was higher than that of CM/GC projects. In terms of change order cost factor and construction intensity, DB projects were found to be superior to CM/GC projects. However, no statistical difference was found.
Climate Governance City to City: Case Studies of the Sierra Club Ready for 100 Network

Year: 2021

description: According to the Intergovernmental Panel on Climate Change (IPCC), even if net atmospheric warming is limited to 1.5 ̊C, threats like extreme precipitation, biodiversity loss, sea level rise, and many other risks pose a serious hazard to the planet. Within the context of inadequate ambition on the international scale and nationally in the U.S., attention towards action on the local scale has grown over the past two decades. In terms of urban context, there is a need for more scholarship which incorporates a larger number of case studies and which addresses smaller cities in addition to the broad theme of justice. Here, I utilize a medium-n case study including cities of a range of sizes across the U.S. which have been recognized by the Sierra Club’s Ready for 100 (RF100) campaign: Athens, GA; Chicago, IL; Columbus, OH; La Mesa, CA; Madison, WI; and Sarasota, FL. RF100 is an initiative aimed at increasing the use of renewable energy across the country while simultaneously promoting equity and justice. Using questionnaires and semi-structured interviews of organizers and officials, I find broad thematic patterns in the challenges and driving factors that campaigns face. When it comes to justice, while the national team engages thoroughly with this complex concept and its various facets, some localities are more successful in this regard than others, as they are more comprehensive and incorporate more of the components of justice identified here through prior research. The hope is that the barriers and drivers identified here, as well as the strengths and shortcomings in certain cities regarding the incorporation of justice elements, can inform both future research and climate governance efforts.

description: To prevent infections local delivery of antibiotics is a useful tool. Especially in bone fractures, vancomycin impregnated bone cements are often used allowing high concentrations of antibiotics at the infection side without high serum concentrations. However, besides potential pathogens, cells involved in tissue regeneration may also be affected by the drug. We investigated the effect of vancomycin on the viability and functionality on osteoblasts, endothelial cells, fibroblasts and skeletal muscle cells. Our results show that the viability of all cells analyzed was reduced by vancomycin and that the observed effects were time and concentration dependent. The most pronounced toxic effect was detected on day three when even the lowest concentration of 0.01 mg/ml led to a significant decrease in proliferation compared to control. Functionality assays of osteoblasts and skeletal muscle cells revealed a sensitive reaction of the cells to the drug, indicating that vancomycin is toxic to these cells during the process of differentiation. These data suggest that the vancomycin administration is critical for cell survival and function. Therefore, the concentration of administered antibiotics needs to be carefully evaluated to find a balance between defense against pathogens and functionality of host cells and tissues.

description: By means of the concept of balanced estimation of diffusion entropy we evaluate reliable scale-invariance embedded in different sleep stages and stride records. Segments corresponding to Wake, light sleep, REM, and deep sleep stages are extracted from long-term EEG signals. For each stage the scaling value distributes in a considerable wide range, which tell us that the scaling behavior is subject- and sleep cycle- dependent. The average of the scaling exponent values for wake segments is almost the same with that for REM segments ($\sim 0.8$). Wake and REM stages have significant high value of average scaling exponent, compared with that for light sleep stages ($\sim 0.7$). For the stride series, the original diffusion entropy (DE) and balanced estimation of diffusion entropy (BEDE) give almost the same results for de-trended series. Evolutions of local scaling invariance show that the physiological states change abruptly, though in the experiments great efforts have been done to keep conditions unchanged. Global behaviors of a single physiological signal may lose rich information on physiological states. Methodologically, BEDE can evaluate with considerable precision scale-invariance in very short time series ($\sim 10^2$), while the original DE method sometimes may underestimate scale-invariance exponents or even fail in detecting scale-invariant behavior. The BEDE method is sensitive to trends in time series. Existence of trend may leads to a unreasonable high value of scaling exponent, and consequent mistake conclusions.

description: Artificial intelligence (AI) comes with a constant development role and recent application by sports consumers. This study aims to investigate the relationships between perceived usefulness, perceived ease of use, user attitudes, and behavioral intention to use AI-based services of the Dominican baseball stadiums of the LIDOM. This work will be based on the Technology Acceptance Model (TAM). As a field method, a test of an AI-based application, "customer relationship management (CRM)" will be conducted that interacts with at least 500 Dominican baseball fans who attend LIDOM stadiums. After using the CRM, a questionnaire will be applied to capture data through testing assumptions and performing a confirmatory multi-factorial analysis to analyze the research hypotheses. The results will indicate three types of consumer considerations: perceived usefulness, perceived ease of use, and attitude of use; with this, it will be possible to determine which has the most significant impact and positively influences their attitudes towards AI. The results of this work will contribute to our knowledge about consumer perception towards AI-based sports facility services.

description: We have analytically solved the spin wave excitations for the intercalated ternary iron-selenide AFe$_{1.5}$Se$_2$ (A=K, Tl) in the $4\times 2$ collinear antiferromagnetic order. It is found that there are one acoustic branch (gapless Goldstone mode) and two gapful optical branches of spin wave excitations with each in double degeneracy. By examining the non-imaginary excitation frequency condition, we can determine the corresponding phase boundary. The exchange couplings between Fe moments in AFe$_{1.5}$Se$_2$ are derived based on the first-principles total energy calculations. The Fe spin is found to be $S=3/2$ through computing the antiferromagnetic quantum fluctuation. And it is further found that a very small spin-orientation anisotropy can remarkably suppress the antiferromagnetic quantum fluctuation. The spin dynamical structure factors are calculated and discussed in association with neutron inelastic scattering experiment.

The Segregation and Integration of Distinct Brain Networks and Their Relationship to Cognition
Creators: name: Cohen, Jessica R.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: A critical feature of the human brain that gives rise to complex cognition is its ability to reconfigure its network structure dynamically and adaptively in response to the environment. Existing research probing task-related reconfiguration of brain network structure has concluded that, although there are many similarities in network structure during an intrinsic, resting state and during the performance of a variety of cognitive tasks, there are meaningful differences as well. In this study, we related intrinsic, resting state network organization to reconfigured network organization during the performance of two tasks: a sequence tapping task, which is thought to probe motor execution and likely engages a single brain network, and an n-back task, which is thought to probe working memory and likely requires coordination across multiple networks. We implemented graph theoretical analyses using functional connectivity data from fMRI scans to calculate whole-brain measures of network organization in healthy young adults. We focused on quantifying measures of network segregation (modularity, system segregation, local efficiency, number of provincial hub nodes) and measures of network integration (global efficiency, number of connector hub nodes). Using these measures, we found converging evidence that local, within-network communication is critical for motor execution, whereas integrative, between-network communication is critical for working memory. These results confirm that the human brain has the remarkable ability to reconfigure its large-scale organization dynamically in response to current cognitive demands and that interpreting reconfiguration in terms of network segregation and integration may shed light on the optimal network structures underlying successful cognition.

The decidability of safety and inevitability properties is shown via the introduction of a priority embedding, a well-quasi-ordering that has not previously been used in well-structured systems. We then show how Priority Channel Systems can compute Fast-Growing functions and prove that the aforementioned verification problems are $\mathbf{F}_{\varepsilon_{0}}$-complete.

Mendelian Randomization Analysis

description: Background. Observational studies have shown that serum magnesium levels are inversely associated risk of cardiovascular disease, but whether this association is causal is unknown. We conducted a Mendelian randomization study to investigate whether serum magnesium levels may be causally associated with coronary artery disease (CAD). Methods: This Mendelian randomization analysis is based on summary-level data from the CARDIoGRAMplusC4D consortium’s 1000 Genomes-based genome-wide association meta-analysis of 48 studies with a total 60,801 CAD cases and 123,504 non-cases. Six single nucleotide polymorphisms (SNPs) associated with serum magnesium levels at genome-wide significance were used as instrumental variables. Results: A genetic predisposition to higher serum magnesium levels was inversely associated with CAD. In conventional Mendelian randomization analysis, the odds ratio of CAD was 0.88 (95% confidence interval [CI]: 0.78 to 0.99; P = 0.03) per 0.1 mmol/L (about 1 standard deviation) increase in genetically predicted serum magnesium levels. Results were consistent in sensitivity analyses using the weighted median and heterogeneity-penalized model averaging methods, with odds ratios of 0.84 (95% CI: 0.72 to 0.98; P = 0.03) and 0.83 (95% CI: 0.71 to 0.96; P = 0.02), respectively. Conclusions: This study based on genetics provides evidence that serum magnesium levels are inversely associated with risk of CAD. Randomized controlled trials elucidating whether magnesium supplementation lowers the risk of CAD, preferably in a setting at higher risk of hypomagnesemia, are warranted.
Period doubling and Blazhko modulation in BL Herculis hydrodynamic models

Year: 2012
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: We present the hydrodynamic BL Herculis-type models which display a long-term modulation of pulsation amplitudes and phases. The modulation is either strictly periodic or it is quasi-periodic, with the modulation period and modulation pattern varying from one cycle to the other. Such behaviour has not been observed in any BL Her variable so far, however, it is a common property of their lower luminosity siblings - RR Lyrae variables showing the Blazhko effect. These models provide a support for the recent mechanism proposed by Buchler & Kollath to explain this still mysterious phenomenon. In their model, a half-integer resonance that causes the period doubling effect, discovered recently in the Blazhko RR Lyrae stars, is responsible for the modulation of the pulsation as well. Although our models are more luminous than is appropriate for RR Lyrae stars, they clearly demonstrate, through direct hydrodynamic computation, that the mechanism can indeed be operational. Of great importance are models which show quasi-periodic modulation - a phenomenon observed in Blazhko RR Lyrae stars. Our models coupled with the analysis of the amplitude equations show that such behaviour may be caused by the dynamical evolution occurring in the close proximity of the unstable single periodic saddle point.

Exploring wind-driving dust species in cool luminous giants I. Basic criteria and dynamical models of M-type AGB stars
Creators: name: Bladh, Sara

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: This work is part of an ongoing effort aiming at identifying the actual wind-drivers among the dust species observed in circumstellar envelopes. In particular, we focus on the interplay between a strong stellar radiation field and the dust formation process. To identify critical properties of potential wind-driving dust species we use detailed radiation-hydrodynamical models which include a parameterized dust description, complemented by simple analytical estimates to help with the physical interpretation of the numerical results. The adopted dust description is constructed to mimic different chemical and optical dust properties in order to systematically study the effects of a realistic radiation field on the second stage of the mass loss mechanism. We see distinct trends in which combinations of optical and chemical dust properties are needed to trigger an outflow. Dust species with a low condensation temperature and a NIR absorption coefficient that decreases strongly with wavelength will not condense close enough to the stellar surface to be considered as potential wind-drivers. Our models confirm that metallic iron and Fe-bearing silicates are not viable as wind-drivers due to their near-infrared optical properties and resulting large condensation distances. TiO2 is also excluded as a wind-driver due to the low abundance of Ti. Other species, such a SiO2 and Al2O3, are less clear-cut cases due to uncertainties in the optical and chemical data and further work is needed. A strong candidate is Mg2SiO4 with grain sizes of 0.1-1 micron, where scattering contributes significantly to the radiative acceleration, as suggested by earlier theoretical work and supported by recent observations.

An Assessment of proposed sex offender mobility and residency restrictions in Nevada
Creators: name: Beecher, Samantha Dawn
Publisher: name: University of Nevada, Las Vegas
Year: 2009

description: This research explores the impact of sex offender exclusion zones and residency restrictions proposed by Nevada Senate Bill 471. This law would prohibit sex offenders from being within 500 feet of places where children congregate and living within 1,000 feet of these places. Analyses conducted using Geographic Information Systems demonstrate the degree to which offender mobility, housing, employment, and access to social services may be restricted should the law be adopted and enforced. Data are also used to assess the potential impact of the law on victimization patterns. Policy implications, data limitations, and suggestions for future research are discussed.

Poisson Process Monitoring, Test and Comparison
Creators: name: Chen, Qing
Publisher: name: University of Nevada, Las Vegas
Year: 2010

description: The task of determining whether a sudden change occurred in the generative parameters of a time series generates application in many areas. In this thesis, we aim at monitoring the change-point of a Poisson process by method, which is characterized by a forward-backward testing algorithm and several overall error control mechanisms. With the application of this proposed method, we declare that Mount Etna is not a simple Poissonian volcano, because two different regimes divided by the change point, January 30th 1974, are identified. The validation procedures, used in a complementary fashion, by the formal hypothesis tests and graphical method will be discussed. In conclusion, the proposed method is easy to implement, and its assessment studies could be conducted based on large scale simulation.

description: We present the analysis of 12227 type-ab RR Lyrae found among the 200 million public lightcurves in the Catalina Surveys Data Release 1 (CSDR1). These stars span the largest volume of the Milky Way ever surveyed with RR Lyrae, covering ~20,000 square degrees of the sky (0 < RA < 360, -22 < Dec < 65 deg) to heliocentric distances of up to 60kpc. Each of the RR Lyrae are observed between 60 and 419 times over a six-year period. Using period finding and Fourier fitting techniques we determine periods and apparent magnitudes for each source. We find that the periods at generally accurate to sigma = 0.002% by comparison with 2842 previously known RR Lyrae and 100 RR Lyrae observed in overlapping survey fields. We photometrically calibrate the light curves using 445 Landolt standard stars and show that the resulting magnitudes are accurate to ~0.05 mags using SDSS data for ~1000 blue horizontal branch stars and 7788 of the RR Lyrae. By combining Catalina photometry with SDSS spectroscopy, we analyze the radial velocity and metallicity distributions for > 1500 of the RR Lyrae. Using the accurate distances derived for the RR Lyrae, we show the paths of the Sagittarius tidal streams crossing the sky at heliocentric distances from 20 to 60 kpc. By selecting samples of Galactic halo RR Lyrae, we compare their velocity, metallicity, and distance with predictions from a recent detailed N-body model of the Sagittarius system. We find that there are some significant differences between the distances and structures predicted and our observations.

Hydrodynamic Characteristics of Thin Porous Barriers

Subjects: classificationCode: 401799
subject: Mechanical engineering not elsewhere classified

description: Perforated breakwaters are often used in coastal management, and porous barriers are simplified forms of these structures. The main objective of this thesis is to assess the hydrodynamic characteristics of thin porous barriers under the action of water waves using both experiments and numerical Smoothed Particle Hydrodynamics simulations. Results indicate that for each barrier, irrespective of the properties of the wave interacting with it, there is a coefficient value that is able to account adequately for the energy dissipation by it. The major outcome from the study is a computational model of flow that is capable of predicting wave-barrier interactions.

description: The generation of distinct cell types in developing tissues depends on establishing spatial patterns of gene expression. Often, this is directed by spatially graded chemical signals-known as morphogens. In the "French Flag model," morphogen concentration instructs cells to acquire specific fates. How this mechanism produces timely and organized cell-fate decisions, despite the presence of changing morphogen levels, molecular noise, and individual variability, is unclear. Moreover, feedback is present at various levels in developing tissues, breaking the link between morphogen concentration, signaling activity, and position. Here, we develop an alternative framework using optimal control theory to tackle the problem of morphogen-driven patterning: intracellular signaling is derived as the control strategy that guides cells to the correct fate while minimizing a combination of signaling levels and time. This approach recovers experimentally observed properties of patterning strategies and offers insight into design principles that produce timely, precise, and reproducible morphogen patterning.

Year: 2013

description: This thesis describes three types of working women in Las Vegas, NV who performed non traditional women's work and who, through their ingenuity and hard work rose to the top of their fields. The first group of women were the little known women war workers at Basic Magnesium Inc who produced magnesium that was so importanat to the war effort. The second group of women worked in a corporate structure and, hired in entry level positions, were able to break the glass ceiling and rise to positions of managenemt. The third group of women were Realtors in Las Vegas who broke the grip on the male dominated Las Vegas Board of Realtors and, through education, inflitrated the board to hold positions as its officers. They became recognised as legitamete busness women and brought professionalism to the industry.
French Indochina: How Gender Shaped the Imperial System

subject: Colonialism
subject: Women
subject: Vietnam

description: This thesis examines the intimate relationships between indigenous Indochinese women and their French counterparts in the 1930s colony of French Indochina, along with understanding the threat the métis children posed and how that subsequently connects with ideas surrounding roles of both gender and race. More specifically, I argue that French imperialists used gender roles and expectations to uphold their system of empire. Utilizing the stories of two women, one French and the other a métisse, I aim to comprehend these complex systems put into place by the French empire, and therefore understand how they functioned to keep people in their place and create a system under which those at the top could benefit.
Formation of the First Stars

subject: FOS: Physical sciences

description: Understanding the formation of the first stars is one of the frontier topics in modern astrophysics and cosmology. Their emergence signaled the end of the cosmic dark ages, a few hundred million years after the Big Bang, leading to a fundamental transformation of the early Universe through the production of ionizing photons and the initial enrichment with heavy chemical elements. We here review the state of our knowledge, separating the well understood elements of our emerging picture from those where more work is required. Primordial star formation is unique in that its initial conditions can be directly inferred from the Lambda Cold Dark Matter (LCDM) model of cosmological structure formation. Combined with gas cooling that is mediated via molecular hydrogen, one can robustly identify the regions of primordial star formation, the so-called minihalos, having total masses of ~10^6 M_sun and collapsing at redshifts z~20-30. Within this framework, a number of studies have defined a preliminary standard model, with the main result that the first stars were predominantly massive. This model has recently been modified to include a ubiquitous mode of fragmentation in the protostellar disks, such that the typical outcome of primordial star formation may be the formation of a binary or small multiple stellar system. We will also discuss extensions to this standard picture due to the presence of dynamically significant magnetic fields, of heating from self-annihalating WIMP dark matter, or cosmic rays. We conclude by discussing possible strategies to empirically test our theoretical models.
