Resource allocation and control on the Lummi Indian reservation : a century of conflict and change in the salmon fishery
Creators: name: Boxberger, Daniel L.
Publisher: name: University of British Columbia
Year: 2010

description: This study focuses on the Lummi Indian fishers of Northwest Washington State, and the manner in which they have been included in and excluded from the commercial fishing industry over the past one hundred years. The approach to be taken in this situation of internal dependency is to examine access to resources. The control of productive resources — land, water, timber, minerals, and fish. — that Indians own or have access to, presents an ideal starting point for understanding Indian underdevelopment. Prior to and immediately after the time the Lummi were confined to a reservation, they were engaged in a traditional fishery that met their needs for subsistence and had the potential to develop into a viable commercial endeavor. The penetration of capital into the commercial salmon fishery of North Puget Sound initially utilized Lummi labor, but the development of new extractive technologies and an increase in the availability of labor of other ethnicities rapidly circumvented the need for Indian labor. Concomitantly, throughout the early 1900s, efforts by the State of Washington to curtail Indian fishing resulted in the Lummi being confined to a small reservation fishery of insignificant commercial potential. In the 1940s, when Lummi exclusion from the fishery was almost total, the need for fishers suddenly became acute, and the Lummi were once again incorporated into the commercial salmon fishery. Nevertheless, the post-war era again saw new developments in the salmon industry, and, no longer needed by the processors, the Lummi were once again squeezed out of the industry. Sympathetic court cases in the late 1960s and early 1970s guaranteed commercially significant fishing opportunity for the Lummi. Nevertheless, the present Lummi salmon fishery is not going to provide the Lummi with a viable economic base. The manner in which the fishery has developed is causing the majority of the economic yield of the fishery to be siphoned off to non-Lummi interests. Utilizing ethnohistorical and ethnographic data, this study examines a dependency approach to understanding Lummi underdevelopment. By focusing primarily on economic and political dependency on the United States Federal Government, this study shows how the Lummi community was incorporated into the dominant society and became a dependent community suffering from chronic underdevelopment, despite access to and utilization of a valuable natural resource.
Codifying Criminal Law in East Africa during the Interwar Period

description: By the time the East Africa Protectorate was proclaimed in 1895, Indian penal and criminal procedure codes had been in effect in the region for nearly 30 years, having first been introduced in Zanzibar. The codes had developed as a result of the difficulties faced by administrative officers in India of applying uncodified English law. Jurists responded by drafting codes that were more suited to local conditions. They were applied throughout East Africa until 1930 when the Colonial Office introduced new codes based on the Queensland Code of 1899. These became the basis of enactments applied in colonies throughout the Empire, such as The Gambia, Cyprus and Fiji. Based on primary sources housed in the Kenya National Archives, the article explores the wider implications of these streams of criminal codification as well as their impact on the administration of criminal justice in East Africa. The competing codes provide a clear example of the transfer of legal knowledge around the Empire, and the dominant position of the global over the local. In addition, the story of the replacement of the Indian codes provides an example of jurisdictional manoeuvering by competing authorities, which was a central characteristic of the colonial world.

description: We investigate when does the Repovš-Semenov Splitting problem for selections have an affirmative solution for continuous set-valued mappings in finite-dimensional Banach spaces. We prove that this happens when images of set-valued mappings or even their graphs are P-sets (in the sense of Balashov) or strictly convex sets. We also consider an example which shows that there is no affirmative solution of this problem even in the simplest case in $\R^{3}$. We also obtain affirmative solution of the Approximate splitting problem for Lipschitz continuous selections in the Hilbert space.

description: We propose a Minimal E_6 Supersymmetric Standard Model (ME$_6$SSM) which allows Planck scale unification, provides a solution to the $μ$ problem and predicts a new Z'. Above the conventional GUT scale $M_{GUT}\sim 10^{16}$ GeV the gauge group corresponds to a left-right symmetric Supersymmetric Pati-Salam model, together with an additional $U(1)_ψ$ gauge group arising from an E_6 gauge group broken near the Planck scale. Below $M_{GUT}$ the ME$_6$SSM contains three reducible $\mathbf{27}$ representations of the Standard Model gauge group together with an additional U(1)_X gauge group, consisting of a novel and non-trivial linear combination of $U(1)_ψ$ and two Pati-Salam generators, which is broken at the TeV scale by the same singlet which also generates the effective $μ$ term, resulting in a new low energy Z' gauge boson. We discuss the phenomenology of the new Z' gauge boson in some detail.

description: Multiple-valued Logic (MVL) circuits are one of the most attractive applications of the Monostable-to-Multistable transition Logic (MML), and they are on the basis of advanced circuits for communications. The operation of such quantizer has two steps : sampling and holding. Once the quantizer samples the signal, it must maintain the sampled value even if the input changes. However, holding property is not inherent to MML circuit topologies. This paper analyses the case of an MML ternary inverter used as a quantizer, and determines the relations that circuit representative parameters must verify to avoid this malfunction.

description: We have identified a sample of 41 low-mass high--oxygen abundance outliers from the mass--metallicity relation of star-forming galaxies measured by Tremonti et al (2004). These galaxies, which have 8.6 < [12 + log(O/H)] < 9.3 over a range of -14.4 > M_B > -19.1 and 7.4 < log M_*/M_solar < 10, are surprisingly non-pathological. They have typical specific star formation rates, are fairly isolated and, with few exceptions, have no obvious companions. Morphologically, they are similar to dwarf spheroidal or dwarf elliptical galaxies. We predict that their observed high oxygen abundances are due to relatively low gas masses, concluding that these are transitional dwarf galaxies nearing the end of their star formation activity.

The Self-Regulated Growth of Supermassive Black Holes

description: We present a series of simulations of the self--regulated growth of supermassive black holes (SMBHs) in galaxies via three different fueling mechanisms: major mergers, minor mergers, and disk instabilities. The SMBHs in all three scenarios follow the same black hole fundamental plane (BHFP) and correlation with bulge binding energy seen in simulations of major mergers, and observed locally. Furthermore, provided that the total gas supply is significantly larger than the mass of the SMBH, its limiting mass is not influenced by the amount of gas available or the efficiency of black hole growth. This supports the assertion that SMBHs accrete until they reach a critical mass at which feedback is sufficient to unbind the gas locally, terminating the inflow and stalling further growth. At the same time, while minor and major mergers follow the same projected correlations (e.g., the $M_{BH}-σ$ and Magorrian relations), SMBHs grown via disk instabilities do not, owing to structural differences between the host bulges. This finding is supported by recent observations of SMBHs in pseudobulges and bulges in barred systems, as compared to those hosted by classical bulges. Taken together, this provides support for the BHFP and binding energy correlations as being more "fundamental" than other proposed correlations in that they reflect the physical mechanism driving the co-evolution of SMBHs and spheroids.

description: Based on the hypothesis that pain is a stand-alone problem, not just a symptom of Post-Traumatic Stress Disorder (PTSD), the effect of group psycho-education (“pain school”) for survivors of the Khmer Rouge regime with pain-PTSD comorbidity was tested in Cambodia in 2015. After baseline assessment comprising pain-related measures (Brief Pain Inventory, Disability Rating Index) and measures for PTSD, anxiety, depression, and distress, 113 subjects were randomized to a waitlist control group (CG, n = 58) and a treatment group (TG, n = 55). After treatment TG improved significantly, with clinically relevant effect size. Effect size was, however, substantially lower than in two prior pilot trials, and the improvement was not maintained at six-month follow-up. The main reason for this is hypothesized to be that the intervention had been delivered in too condensed a format. It is concluded that treatment addressing pain can also ameliorate mental health problems, implying that more attention should be paid to pain treatment for subjects suffering from pain/PTSD comorbidity.

The development of resistance to anticancer agents
Creators: name: Coldman, Andrew James
Publisher: name: University of British Columbia
Year: 2010

description: The mechanism of resistance of tumor cells to chemotherapeutic agents is explored using probabilistic methods where it is assumed that resistant cells arise spontaneously with a defined frequency. The resistance process is embedded in a discrete time Markov branching process which models the growth of the tumor and contains three seperate cell types: stem, transitional and end cells. Using the asymptotic properties of such models it is shown that the proportion of each type of cell converge to constants almost surely. It is shown that the parameters relating to stem cell behaviour determine the asymptotic behaviour of the system. It is argued that for biologically likely parameter values, cure of the tumor will occur if, and only if, all stem cells are eliminated. A model is developed for the acquisition of resistance by stem cells to a single drug. Probability generating functions are derived which describe the behaviour of the process after an arbitrary sequence of drug treatments. The probability of cure, defined as the probability of ultimate extinction of the stem cell compartment, is characterised as the central quantity reflecting the success of therapeutic intervention. Expressions for this function are derived for a number of experimental situations. The effects of variation in the parameter values are examined. The model is extended to the case where two anticancer drugs are available and formulae for the probability of cure are developed. The problem of therapeutic scheduling is examined and under situations where drugs are of "equal" effectiveness, but may not be given together, it is shown that the mean number of tumor cells is minimised by sequential alternation of the drugs. The models are applied to data collected on the L1210 leukemia treated by the drugs Cyclophosphamide and Arabinosylcytosine. In both cases the analysis of the data provide evidence that resistant cells arise spontaneously with a frequency of approximately 10⁻⁷ per division. When applied to human breast cancer, the model indicates that neoadjuvant therapy is unlikely to greatly influence the likelihood that the patient will die from the growth of drug-resistant cells.

description: Our study aims to improve the efficiency of moderate integrated management systems in the Moroccan health sector for public or private organizations. Our analytical approach is based on a new dual 2RM (Risk Minimization and Richness Maximization) as a guiding vector, allowing the implementation of an oriented continuous improvement toward the governance and sustainable performance of the sector. Admittedly, good management of information flows is necessary for making a good decision, especially in the health sector impacted by the health crisis of covid 19, which plays a fundamental role in economic, security and social life. Several methodologies, such as SMED, QRQC and 5S, which derive from the Toyota Production System School, are introduced in this study. Thus, we propose processes and a dynamic algorithm to follow and achieve the objectives of these methodologies and ensure a high level of performance and quality of health services.

These processes and algorithms are based on the collection of information allowing the exploration of the type of anomaly and malfunction, followed by using a user's guide for the oriented continuous improvement by calculating indexes proposed in this article according to the dual approach. Using this user's guide allows the management of public or private health establishments to avoid the redundancy of errors and to consolidate performance towards optimizing the overall quality of service and profitability.

description: An extension of the Legendre transform to non-convex functions with vanishing Hessian as a mix of envelope and general solutions of the Clairaut equation is proposed. Applying this to systems with constraints, the procedure of finding a Hamiltonian for a degenerate Lagrangian is just that of solving a corresponding Clairaut equation with a subsequent application of the proposed Legendre-Clairaut transformation. In this way the unconstrained version of Hamiltonian equations is obtained. The Legendre-Clairaut transformation presented is involutive. We demonstrate the origin of the Dirac primary constraints, along with their explicit form, and this is done without using the Lagrange multiplier method.

description: We present a simple unifying model for crystallization and melting temperatures by showing that homogeneous nucleation and phase transformations driven by thickening of pre-existing surface layers are limiting conditions of the more general heterogeneous nucleation case. Furthermore, to a first approximation all these processes can be described by an extended classical nucleation theory. The model can also be applied to phase transition temperatures in confined volumes, provided reliable values for the interfacial tensions within the systems are determinable. The expected melting and crystallization temperature for any transformation pathway can then be predicted.

description: Several nanoelectronic devices have been already proved. However, no architecture which makes use of them provides a feasible opportunity to build medium/large systems. Nanoarchitecture proposals only solve a small part of the problems needed to achieve a real design. In this paper, we propose and analyze a cell architecture that overcomes most of those at the gate level. Using the cell structure we build 2 and 3-input NAND gates showing their error probabilities. Finally, we outline a method to further improve the structure's tolerance by taking advantage of interferences among nanodevices. Using this improvement we show that it is possible to reduce the output standard deviation by a factor larger than $\sqrt{2}$ and restitute the signal levels using nanodevices.

Combatir las bacterias patógenas actualmente se han convertido en un desafío, ya que presentan una alta resistencia a antibióticos por lo cual algunos antibióticos del mercado farmacéutico han presentado una nula inhibición contra éstas. Las causas de este fenómeno se deben ya sea al uso inadecuado por el paciente, diagnósticos incorrectos o pruebas microbianas no impuestas, que han generado estas consecuencias. Por lo tanto, los fenotipos de resistencia a antibióticos resaltan la importancia de realizar pruebas de sensibilidad o resistencia a antibióticos en microorganismos, para generar un adecuado uso en el manejo de las infecciones bacterianas. Estas prácticas son esenciales para combatir eficazmente este desafío global en la salud pública; como es el caso de E. coli [1]. En esta infigrafía se muestra un ejemplo de la obtención del perfil de susceptibilidad de cepas aisladas del río Nexapa y se discute brevemente su resistencia.

description: Planet transit events present as attractive targets for the ultra-high-resolution capabilities afforded by optical interferometers. Herein is presented an evaluation of the possibility of detection of such events through measurement of high-precision closure phases with the MIRC instrument on the CHARA Array. Recovery of the transit position angle upon the sky appears readily achievable with the existing capabilities of the instrument, along with characterization of other system parameters, such as stellar radius, planet radius, and other parameters of the transit event. This technique is the only one presently available that can provide a transiting planet's orbital plane position angle, and can directly determine the planet's radius independent of any outside observations, appearing able to improve substantially upon other determinations of that radius. Additional directly observed parameters - also not dependent upon transit photometry or spectroscopy - include impact parameter, transit ingress time, transit velocity and stellar radius.

description: We review the theoretical status of b to s hadronic penguin decays in the Standard Model and beyond. We summarize the main theoretical tools to compute Branching Ratios and CP asymmetries for b to s penguin dominated nonleptonic decays, and discuss the theoretical uncertainties in the prediction of time-dependent CP asymmetries in this processes. We consider general aspects of b to s transitions beyond the Standard Model. Then we present detailed predictions in supersymmetric models with new sources of flavor and CP violation.

description: Silicon-based CMOS technologies are predicted to reach their ultimate limits by the middle of the next decade. Research on nanotechnologies is actively conducted, in a world-wide effort to develop new technologies able to maintain the Moore's law. They promise revolutionizing the computing systems by integrating tremendous numbers of devices at low cost. These trends will have a profound impact on the architectures of computing systems and will require a new paradigm of CAD. The paper presents a work in progress on this direction. It is aimed at fitting requirements and constraints of nanotechnologies, in an effort to achieve efficient use of the huge computing power promised by them. To achieve this goal we are developing CAD tools able to exploit efficiently these huge computing capabilities promised by nanotechnologies in the domain of simulation of complex systems composed by huge numbers of relatively simple elements.

Prandtl number dependence of compressible convection: Flow statistics and convective energy transport

description: (abridged) Context: The ratio of kinematic viscosity to thermal diffusivity, the Prandtl number, is much smaller than unity in stellar convection zones. Aims: To study the statistics of convective flows and energy transport as functions of the Prandtl number. Methods: Three-dimensional numerical simulations convection in Cartesian geometry are used. The convection zone (CZ) is embedded between two stably stratified layers. Statistics and transport properties of up- and downflows are studied separately. Results: The rms velocity increases with decreasing Prandtl number. At the same time the filling factor of downflows decreases and leads to stronger downflows at lower Prandtl numbers, and to a strong dependence of overshooting on the Prandtl number. Velocity power spectra do not show marked changes as a function of Prandtl number. At the highest Reynolds numbers the velocity power spectra are compatible with the Bolgiano-Obukhov $k^{-11/5}$ scaling. The horizontally averaged convected energy flux ($\overline{F}_{\rm conv}$) is independent of the Prandtl number within the CZ. However, the upflows (downflows) are the dominant contribution to the convected flux at low (high) Prandtl number. These results are similar to those from Rayleigh-Benárd convection in the low Prandtl number regime where convection is vigorously turbulent but inefficient at transporting energy. Conclusions: The current results indicate a strong dependence of convective overshooting and energy flux on the Prandtl number. Numerical simulations of astrophysical convection often use Prandtl number of unity. The current results suggest that this can lead to misleading results and that the astrophysically relevant low Prandtl number regime is qualitatively different from the parameters regimes explored in typical simulations.

Choice Overload and Its Moderators: How and Why People Struggle with Large Assortment of Goods
Creators: name: Liu, Xinyuan
Publisher: name: University of Chicago

Subjects: subject: Choice overload
subject: Assortments
subject: Decision making

description: Choice overload, which means that large assortment may have negative effect on people’ s decisions and behaviors, has already been tested in many different research papers (Iyengar & Lepper, 2000; Chernev, 2003; Gourville & Soman, 2005). However, when and how choice overload affect people’s behavior still remains open, which makes it valuable for us to study the effect of large assortment in a more comprehensive scenario. In this research, I test how the assortment size affect choice overload in a scenario including four related factors: choice set complexity, decision task difficulty, preference uncertainty, and decision goal. The purpose of the research is to study the effect of all the four moderators and assortment size on choice overload in a single comparable situation, which allow us to model the decision-making scenario in the real life and test the basic and interaction effect of those factors.

description: We consider the N-body Schrödinger dynamics of bosons in the mean field limit with a bounded pair-interaction potential. According to the previous work \cite{AmNi}, the mean field limit is translated into a semiclassical problem with a small parameter $ε\to 0$, after introducing an $ε$-dependent bosonic quantization. The limit is expressed as a push-forward by a nonlinear flow (e.g. Hartree) of the associated Wigner measures. These object and their basic properties were introduced in \cite{AmNi} in the infinite dimensional setting. The additional result presented here states that the transport by the nonlinear flow holds for rather general class of quantum states in their mean field limit.

description: The Optimized Perturbation Theory (OPT) method, at finite temperature and finite chemical potential, is applied to the field theory model for polyacetylene. The critical dopant concentration in trans-polyacetylene is evaluated and compared with the available experimental data and with previous calculations. The results obtained within the OPT go beyond the standard mean field (or large-N) approximation (MFA) by explicitly including finite N effects. A critical analysis of the possible theoretical prescriptions to implement and interpret these corrections to the mean field results, given the available data, is given. For typical temperatures probed in the laboratory, our results show that the critical dopant concentration is only weakly affected by thermal effects.

description: Order(N) Tight-Binding Molecular Dynamics (TBMD) simulations are performed to investigate the thermal stability of (10,10) metallic Single-Walled Carbon Nanotubes (SWCNT). Periodic boundary conditions (PBC) are applied in axial direction. Velocity Verlet algorithm along with the canonical ensemble molecular dynamics (NVT) is used to simulate the tubes at the targeted temperatures. The effects of slow and rapid temperature increases on the physical characteristics, structural stability and the energetics of the tube are investigated and compared. Simulations are carried out starting from room temperature and the temperature is raised in steps of 300K. Stability of the simulated metallic SWCNT is examined at each step before it is heated to higher temperatures. First indication of structural deformation is observed at 600K. For higher heat treatments the deformations are more pronounced and the bond breaking temperature is reached around 2500K. Gradual (slow) heating and thermal equilibrium (fast heating) methods give the value of radial thermal expansion coefficient in the temperature range between 300K-600K as 0.31x10^{-5}(1/K) and 0.089x10^{-5}(1/K), respectively. After 600K, both methods give the same value of 0.089x10^{-5}(1/K). The ratio of the total energy per atom with respect to temperature is found to be 3x10^{-4} eV/K.

description: A novel nanostructured electrochemical immunsensor for the determination of progesterone is reported. The approach combines the properties of gold nanoparticles with the use of a graphite-Teflon composite electrode matrix, into which gold nanoparticles are incorporated by simple physical inclusion. The antibody anti-progesterone was directly attached to the electrode surface. The immunosensor functioning is based on competitive assay between progesterone and alkaline phosphatase-labelled progesterone. Monitoring of the affinity reaction was accomplished by the electrochemical oxidation of 1-naphtol. Modification of the graphite -Teflon electrode matrix with gold nanoparticles improves substantially the electrooxidation response of 1-naphtol. Using a detection potential of +0.3V, a detection limit for progesterone of 0.84 ng ml-1 was obtained. Analysis of seven milk samples spiked at a 3.5 ng ml-1 progesterone concentration level yielded a mean recovery of 101+6%. Detection of the antigen-antibody reaction with a graphite - Teflon - colloidal - gold - Tyrosinase electrode, using phenylphosphate as alkaline phosphatase substrate to generate phenol, which is subsequently reduced at -0.1 V at the composite electrode, produced a high improvement in the sensitivity for progesterone detection

description: Le but de cette étude est de vérifier si la gestion des compétences et des carrières peut motiver les salariés en entreprise dans le contexte malien. L’étude cherche aussi à comprendre la nature du lien existant entre la gestion des compétences, des carrières et la motivation des salariés. Pour réaliser ce travail, nous avons fait une étude quantitative à l’aide des questionnaires adressés à cent vingt (120) salariés de six entreprises privées, toutes évoluant dans le secteur de l’éducation. Nous avons utilisé la technique dite boule neige pour obtenir cet échantillon. Le questionnaire a été le moyen de collecter les informations se rapportant aux politiques de gestion des compétences et des carrières adoptées dans les structures enquêtées. Nos résultats révèlent qu’une meilleure gestion des compétences et des carrières est gage de motivation des salariés. Elle entraine satisfaction, la fidélisation, compétitivité, la performance et le bien-être. Nos résultats indiquent que la gestion des compétences, des carrières et le processus de motivation des salariés sont indissociables. Notre recherche a des implications managériales, car elle a permis d’établir un parallèle entre la gestion des compétences, des carrières et la motivation des salariés.

description: The regular monitoring of flat-spectrum radio quasars (FSRQs) in $γ$-rays by Fermi-LAT since past 12 years indicated six sources who exhibited extreme $γ$-ray outbursts crossing daily flux of $10^{-5}$ photons/cm$^{2}$/s. We obtained nearly-simultaneous multi-wavelength data of these sources in radio to $γ$-ray waveband from OVRO, Steward Observatory, SMARTS, Swift-UVOT, Swift-XRT, and Fermi-LAT. The time-averaged broadband Spectral Energy Distributions (SEDs) of these sources in quiescent states were studied to get an idea about the underlying baseline radiation processes. We modeled the SEDs using one-zone leptonic synchrotron and inverse-Compton emission scenario from broken power-law electron energy distribution inside a spherical plasma blob, relativistically moving down a conical jet. The model takes into account inverse-Compton scattering of externally and locally originated seed photons in the jet. The big blue bumps visible in quiescent state SEDs helped to estimate the accretion disk luminosities and central black hole masses. We found a correlation between the magnetic field inside the emission region and the ratio of emission region distance to disk luminosity, which implies that the magnetic field decreases with an increase in emission region distance and decrease in disk luminosity, suggesting a disk-jet connection. The high-energy index of the electron distribution was also found to be correlated with observed $γ$-ray luminosity as $γ$-rays are produced by high-energy particles. In most cases, kinetic power carried by electrons can account for jet radiation power as jets become radiatively inefficient during quiescent states.
