Risk and Private Military Work

description: To date geography has paid scant attention to private military contracting. Other disciplines have studied the topic, but their work is state-centric. In this paper I examine private military contracting through a geoeconomic lens and make four arguments. First, the heightened security risks of the contemporary era cannot be explained solely as a result of states’ decision to cede their monopolies over the means of violence. We must also examine the private military firms that have created new monopolies and the strategies they use to manage and distribute risk. Second, the industry has increased risk in the world system by offloading security risks onto their employees. This “responsibility over rights” management model provides inadequate human rights training and battlefield adjudication procedures for contractors and civilians alike. Third, the geography of private military work does not always conform to the global division of labor between north and south. Instead, private military work creates a class of work that cuts across social and geographic divides. Finally, while activists should encourage states to regulate the industry, they should also push it to reform employment practices since private military firms are increasingly global in scope.

description: In recent years, a large number of smart devices will be connected in Internet of Things (IoT) using an ad hoc network, which needs more frequency spectra. The cognitive radio (CR) technology can improve spectrum utilization in an opportunistic communication manner for IoT, forming a promising paradigm known as cognitive radio ad hoc networks,CRAHNs. However, dynamic spectrum availability and mobile devices/persons make it difficult to develop an efficient data transmission scheme for CRAHNs under an obstacle environment. Opportunistic routing can leverage the broadcast nature of wireless channels to enhance network performance. Inspired by this, in this paper, we propose an Obstacle aware Opportunistic Data Transmission scheme (OODT) in CRAHNs from a computational geometry perspective, considering energy efficiency and social features. In the proposed scheme, we exploit a new routing metric, which is based on an obstacle avoiding algorithm using a polygon boundary 1-searcher technology, and an auction model for selecting forwarding candidates. In addition, we prove that the candidate selection problem is NP-hard and propose a heuristic algorithm for candidate selection. The simulation results show that the proposed scheme can achieve better performance than existing schemes.

description: Food assistance programs contribute to the improvement of the nutritional and economic well-being of low-income Americans. Through general assistance programs, such as the Food Stamp Program, and programs designed to meet the needs of specific target groups, USDA is working to improve diets on Indian reservations by making available more nutritious foods and nutrition education. Although such programs have helped to improve dietary levels of low-income American Indian households, there are persistent indications that hunger, malnutrition, diet-related diseases, and other conditions symptomatic of chronic poverty remain prevalent on many reservations. In 1977, Congress established the Food Distribution Program on Indian Reservations (FDPIR) to provide supplemental food to low-income households living on or near rural American Indian reservations as an acceptable alternative to Food Stamp Program benefits. Because of the remote and geographically dispersed locations of many reservations and other Indian lands, many otherwise eligible American Indian families have been unable to participate in the Food Stamp Program, because access to food stamp offices and grocery stores has been difficult. This article reports some information from a 1988 study commissioned by USDA's Food and Consumer Service (FCS) to assess the operation of the FDPIR and to identify the socioeconomic characteristics of the program's clientele. The results of this study (published in 1990) provide the primary source of data and specific information used in this article.

description: The rate of the $^{25}$Al($p$,$γ$)$^{26}$Si reaction is one of the few key remaining nuclear uncertainties required for predicting the production of the cosmic $γ$-ray emitter $^{26}$Al in explosive burning in novae. This reaction rate is dominated by three key resonances ($J^π=0^{+}$, $1^{+}$ and $3^{+}$) in $^{26}$Si. Only the $3^{+}$ resonance strength has been directly constrained by experiment. A high resolution measurement of the $^{25}$Mg($d$,$p$) reaction was used to determine spectroscopic factors for analog states in the mirror nucleus, $^{26}$Mg. A first spectroscopic factor value is reported for the $0^{+}$ state at 6.256 MeV, and a strict upper limit is set on the value for the $1^{+}$ state at 5.691 MeV, that is incompatible with an earlier ($^{4}$He,$^{3}$He) study. These results are used to estimate proton partial widths, and resonance strengths of analog states in $^{26}$Si contributing to the $^{25}$Al($p$,$γ$)$^{26}$Si reaction rate in nova burning conditions.

title: The Simulated Self - Fiction Reading and Narrative Identity
Creators: name: Mathies, Susanne
Publisher: name: The Open University
Year: 2019

description: What does it mean to read, and to engage with, a work of fiction? In this thesis, I develop an account that explores the relation between fiction reading and the reader’s narrative identity. Starting with an investigation of Paul Ricoeur’s account of narrative identity and of Kendall Walton’s account of the nature of representations, I set out and argue for my own model of fiction reading. My account is based on two starting assumptions: first, that human beings are entangled in stories throughout their lives, and second, that emotions are complex and have a narrative structure. I argue that during the reading process, the fiction reader creates her own narratives which contain not only the story provided by the work of fiction, but also event sequences from her own experiential memories. I investigate the creation and the influence of self-conscious emotions which are generated during the reading process, especially when a reader identifies with a fictional character from within. I consider how and why these fiction-induced emotions can continue after the reading is finished, and how these emotions can motivate the reader to engage in self-reflection and to refigure her self-narrative. My account examines a new topic: the interactive influence of fiction reading and the fiction reader’s narrative identity.
Placing the Militia Occupation of the Malheur National Wildlife Refuge in Harney County, Oregon
Creators: name: Gallaher, Carolyn
Publisher: name: American University
Year: 2023

description: This intervention examines the recent militia occupation of the Malheur National Wildlife Refuge in Oregon. There is no consensus on how to place the group. Some commentators suggest the group was white supremacist. Others argue that it was animated by religious fanaticism. Still others emphasize the group’s grievances with the Bureau of Land Management. I argue here that the Malheur occupiers’ politics cannot be understood with reference to a single identity position. Rather, we need to focus on the group’s anti-government rhetoric because it funnels and shapes multiple interests at once. Here I examine how the group’s anti-government rhetoric frames race and class interests. In terms of race, I argue that anti-government rhetoric obscures the white interests behind the occupation. This concealment is based on a selective reading of history that emphasizes the end of settlement, when the government took ownership of land not claimed during the settlement period, instead of the stage leading up to it, when the government seized Indigenous land for white settlement. So construed, the occupiers could claim they were taking the ‘people’s’ land back from the government rather than engaging in a second round of white theft of Indigenous land. In terms of class, I argue that because the occupiers framed their fight as against government tyranny instead of as for privatization, the occupiers did not have to confront the inequities that come with privatization.

description: I n an era of budgetary and deficit pressures, food-assistance programs are headed for change as part of an overall effort to scale back on Government-funded welfare programs. Most agree that the U.S. welfare system needs reform to reduce costs, improve the effectiveness of the programs, reduce dependency, and provide incentives for recipients. Proposals from the Executive and Legislative branches, as well as the States, offer modifications to current programs, including those providing food assistance. There is much discussion on how to make the programs more efficient while continuing to assist the needy. The major proposals would reduce funding and eligibility for some Federal programs and transfer control of others to the States under a block grant with a fixed spending limit. Impacts of changes in the Nation's food and nutrition assistance programs will extend beyond the programs' 45 million recipients to the rest of the food sector and the larger economy. With reductions in food assistance, national food spending would decrease, as would the demand for agricultural commodities (particularly meats), commodity prices, and farm income. Nonfood sectors would also be affected. The extent of these changes depends on the size of the program cuts, the form of the new programs, and whether the savings are used to reduce the Federal budget deficit or to cut taxes.

description: The Type Ia SN 2000cx exhibited multiple peculiarities, including a lopsided B-band light-curve peak that does not conform to current methods for using shapes of light curves to standardize SN Ia luminosities. We use the parameterized supernova synthetic-spectrum code SYNOW to study line identifications in the photospheric-phase spectra of SN 2000cx. Previous work established the presence of Ca II infrared-triplet features forming above velocity about 20,000 km/s, much higher than the photospheric velocity of about 10,000 km/s. We find Ti II features forming at the same high velocity. High-velocity line formation is partly responsible for the photometric peculiarities of SN 2000cx: for example, B-band flux blocking by Ti II absorption features that decreases with time causes the B light curve to rise more rapidly and decline more slowly than it otherwise would. SN 2000cx contains an absorption feature near 4530 A that may be H-beta, forming at the same high velocity. The lack of conspicuous H-alpha and P-alpha signatures does not necessarily invalidate the H-beta identification if the high-velocity line formation is confined to a clump that partly covers the photosphere and the H-alpha and P-alpha source functions are elevated relative to that of resonance scattering. The H-beta identification is tentative. If it is correct, the high-velocity matter must have come from a nondegenerate companion star.

description: Background: Instruments that measure exposure to bullying and harassment of students learning in a clinical workplace environment (CWE) that contain validity evidence are scarce. The aim of this study was to develop such a measure and provide some validity evidence for its use. Method: We took an instrument for detecting bullying of employees in the workplace, called the Negative Acts Questionnaire – Revised (NAQ-R). Items on the NAQ-R were adapted to align with our context of health professional students learning in a CWE and added two new factors of sexual and ethnic harassment. This new instrument, named the Clinical Workplace Learning NAQ-R, was distributed to 540 medical and nursing undergraduate students and we undertook a Confirmatory Factor Analysis (CFA) to investigate its construct validity and factorial structure. Results: The results provided support for the construct validity and factorial structure of the new scale comprising five factors: workplace learning-related bullying (WLRB), person-related bullying (PRB), physically intimidating bullying (PIB), sexual harassment (SH), and ethnic harassment (EH). The reliability estimates for all factors ranged from 0.79 to 0.94. Conclusion: This study provides a tool to measure the exposure to bullying and harassment in health professional students learning in a CWE.

description: The temperature and magnetic field dependencies of Ni-Mn-Ga polycrystals deformation are investigated. Ingots were prepared by arc-melting in argon atmosphere and further annealing. A training procedure (cycling across the martensitic transition point) for the two-way shape-memory effect was performed with Ni$_{2.16}$Fe$_{0.04}$Mn$_{0.80}$Ga samples. Changes in sample deformations were noticed with changing the magnetic field at a constant temperature. The first cycle deformation increment as compared with the initial value (in the austenitic state at zero field) in the course of the martensitic transition was 0.29%, and 0.41% and 0.48% for the second and third cycles, respectively.

title: A Novel Multi-View Table Tennis Umpiring Framework
Creators: name: Myint, Hnin
Publisher: name: The Open University
Year: 2019

description: This research investigates the development of a low-cost multi-view umpiring framework, as an alternative to the current expensive systems that are almost exclusively restricted to elite professional sports. Table tennis has been selected as the testbed because, while automating the process is challenging, it has many different complex match elements including the service, return and rallies, which are governed by a strict set of regulations. The focus is mainly on the rally element rather than the whole match. Ball detection and tracking in video frames are undertaken to determine reliably the ball position relative to key reference objects like the table surface and net, and the ball’s flight path is used to determine the rally’s status. While a low-cost option has benefits, it is technically challenging due to the limited number of cameras and generally low video resolution used. This thesis presents a portable multi-view umpiring framework that identifies each state change in a rally. It makes three significant contributions to knowledge: i) a reliable ball detection strategy that accurately detects the location of the ball in low-resolution sequences; ii) a novel framework for ball tracking using a multi-view system, and iii) a new state-machine based evaluation system for analysing table tennis rallies. In a series of ten different test scenarios, the system achieved an average of 94% system detection rate and 100% accurate decisions. A test sequence of duration 1 s can be processed in 8 s, leading to a delay of only 7 s, which is considered acceptable for practical purposes. This solution has the potential to reform the way matches are umpired, providing objectivity in resolving disputed decisions. It affords an economic technology for amateur players, while the multi-view facility is extendible to other relevant ball-based sports. Finally, the ball flight path analysis mechanism can be a valuable training tool for skills development.

title: Development of a Multimodal MRI Study to Characterize Morpho-Functional Features in Rodent Models of Alzheimer's Disease
Creators: name: Tolomeo, Daniele
Publisher: name: The Open University
Year: 2019

description: Alzheimer’s Disease (AD) is the most common form of dementia, recognized by the World Health Organization as a global public health priority. It is a complex pathology characterized by the accumulation of the Amyloid-β (Aβ) peptide as extracellular plaques and of the intracellullar neuro fibrillary tangles (NFT) alongside with different events, such as chronic neuroinflammation and astrogliosis. None of the existing biomarkers is simultaneously specific for the pathology and sensitive to its progression. Metabolic and functional alterations are the earliest events described in the AD pathological cascade but shared with other form of dementia, while specific structural alterations occurs in a later stage of the disease. The use of transgenic models could simplify the development of new imaging biomarkers that would enable early diagnosis and making new treatments more effective. The objective of this work was to develop a multi-modal panel of magnetic resonance imaging (MRI) techniques and automated analysis pipelines, characterized by a high translational impact, in order to investigate the metabolic, functional and structural alterations in the brains of AD transgenic models. Results obtained in the APP23 transgenic mouse show that chemical exchange saturation transfer (CEST) imaging can be used to detect alterations in the brain uptake of the glucose analogue 2-deoxy-d-glucose (2DG) with a better resolution than PET and without the need of radioactive tracers. Moreover, a longitudinal study highlighted that significant structural and metabolic alterations can be found only in a late stage of the pathology. Furthermore, an advanced pipeline for the analysis of the rodent brain functional connectivity has been developed. This thesis demonstrates that the advantage to the experimental design adopted is simplifying longitudinal studies of the same animal cohort. The translation of the analysis pipelines adopted in human studies enables more powerful results and reduces the number of animals involved in research.

description: Co3Sn2S2, a quasi-two-dimensional system with kagome lattice, has been found as a magnetic Weyl semimetal recently. In this work, the anisotropies of magnetization and transport properties of Co3Sn2S2 were investigated. The high field measurements reveal a giant magnetocrystalline anisotropy with an out-of-plane saturation field of 0.9 kOe and an in-plane saturation field of 230 kOe at 2 K, showing a magnetocrystalline anisotropy coefficient Ku up to 8.3 * 10^5 J m-3, which indicates that it is extremely difficult to align the small moment of 0.29 μB/Co on the kagome lattice from c axis to ab plane. The out-of-plane angular dependences of Hall conductivity further reveal strong anisotropies in Berry curvature and ferromagnetism, and the vector directions of both are always parallel with each other. For in-plane situation, the longitudinal and transverse measurements for both I parallel a and I perpendicular a cases show that the transport on the kagome lattice is isotropic. These results provide essential understanding on the magnetization and transport behaviors for the magnetic Weyl semimetal Co3Sn2S2.

description: BACKGROUND: Women in Africa disproportionately acquire HIV-1. Understanding which women are most likely to acquire HIV-1 can guide focused prevention with pre-exposure prophylaxis (PrEP). Our objective is to identify women at highest risk of HIV-1 and estimate PrEP efficiency at different sensitivity levels.
METHODS: Nationally representative data were collected from 2015-2019 from 15 population-based household surveys. This analysis included women aged 15-49 who tested HIV-1 sero-negative or had recent HIV-1. Least absolute shrinkage and selection operator regression models were fit with 28 variables to predict recent HIV-1. Models were trained on the full population and internally cross-validated. Performance was evaluated using area under the receiver-operating-characteristic curve (AUC), sensitivity, and number needed to treat (NNT) with PrEP to avert one infection.
RESULTS: Among 209,012 participants 248 had recent HIV-1 infection, representing 118 million women and 402,000 (95% CI: 309,000-495,000) new annual infections. Two variables were retained in the model: living in a subnational area with high HIV-1 viremia and having a sexual partner living outside the home. Full-population AUC was 0.80 (95% CI: 0.76-0.84); cross-validated AUC was 0.79 (95% CI: 0.75-0.84). At a sensitivity of 33%, up to 130,000 cases could be averted if 7.9 million women were perfectly adherent to PrEP; NNT would be 61. At a sensitivity of 67%, up to 260,000 cases could be averted if 25.1 million women were perfectly adherent to PrEP; the NNT would be 96.
CONCLUSIONS: This risk assessment tool was generalizable, predictive, and parsimonious with tradeoffs between reach and efficiency.

It could be interpreted as philosophy with dramatic elements, or drama with philosophical arguments, or possibly a mixture of both. This has made it difficult for scholars to gain a clear understanding of Plato and his dialogues.

To date, little attention has been paid by commentators to the dramatic and literary aspects of Republic Books II to X. This study has been inspired by the recent debates concerning the dramatic and literary aspects of Plato's dialogues and especially the debates concerning the connections between the philosophical, dramatic and literary aspects of these works. It attempts to add to the scholarship to date by carrying out a detailed investigation of the Republic as a whole, rather than focusing primarily on Book I.

This enquiry considers the philosophical and dramatic role of the respondents and Socrates in the Republic. Particular attention is paid to the theme of uncertainty and problematising which runs through the dialogue in the different methods of enquiry adopted by Socrates and the respondents.

The examples considered of the input from the respondents, especially Thrasymachus, Glaucon and Adeimantus, together with Socrates' reaction to these, alert the reader to some important connections between the philosophical and dramatic aspects of the Republic. These connections would not become evident from a study of the work from a purely philosophical or literary perspective. They help the reader to gain a broader understanding of the work as a whole and what message or messages Plato may have been trying to convey. They also suggest the need for caution in selecting a particular interpretation of the dialogue as a whole.

description: The land tenure system in Lebowa is similar to most traditional African systems. Both communal and individualised tenure have been advocated by different experts. A survey was conducted to determine the attitudes of Lebowa smallholders and leaders to land tenure systems. The majority of smallholders are in favour of change. The response from traditional leaders seems to be ambiguous. Both smallholders and non-traditional leaders favour more individualised tenure with more land being farmed by the better farmers. In general, there seems to be an interest in modernisation.

description: The investigation of the behavior of both classical and quantum systems on non-Euclidean surfaces near the phase transition point represents an interesting research area of modern physics. In the case of classical spin systems, a generalization of the Corner Transfer Matrix Renormalization Group algorithm has been developed and successfully applied to spin models on infinitely many regular hyperbolic lattices. In this work, we extend these studies to specific types of lattices. It is important to say that no suitable algorithms for numerical analysis of ground-states of quantum systems in similar conditions have been implemented yet. In this work, we offer a particular solution by proposing a variational numerical algorithm Tensor Product Variational Formulation, which assumes a quantum ground-state written in the form of a low-dimensional uniform tensor product state. We apply the Tensor Product Variational Formulation to three typical quantum models on a variety of regular hyperbolic lattices. The main outcomes are the following: (1) We propose an algorithm for calculation and classification of the thermodynamic properties of the Ising model on triangular-tiled hyperbolic lattices. In addition, we investigate the origin of the mean-field universality on a series of weakly curved lattices. (2) We develop the Tensor Product Variational Formulation algorithm for the numerical analysis of the ground-state of the quantum systems on the hyperbolic lattices. (3) We study quantum phase transition phenomena for the three selected spin models on various types of the hyperbolic lattices including the Bethe lattice.

description: William (Willie) Alexander Robertson was an uncle. He was son of George Robertson and Jessie Robertson (née Carnie). He was born on 10/04/1879 at Midmill, Kintore, Scotland. He was a ploughman and then a marine engineer with Thorneycroft, London, working on power boats. He took a Thorneycroft boat to Honduras and stayed there. He worked in locating mahogany for logging and timber extraction. His brothers, James Charles Robertson and John Cameron Robertson, and cousins William James Carnie and John Carnie all served in the armed services in the First World War.William Alexander Robertson returned from Honduras to enlist in the First World War. He served in the Royal Naval Air Service with rank up to Petty Officer.In 1919 he returned to Honduras. In 1940 he brought a party of Honduran lumberjacks to cut timber in Scotland. In 1945 he returned to Honduras. On 29/03/1954 he died of stab wounds at Belize City, British Honduras, after being attacked by a former employee.His decorations have not been located.
Massive black hole remnants of the first stars I: abundance in present-day galactic haloes

description: We investigate the possibility that present-day galaxies and their dark matter haloes contain a population of massive black holes (MBHs) that form by hierarchical merging of the black hole remnants of the first stars in the Universe. Some of the MBHs may be large enough or close enough to the centre of the galactic host that they merge within a Hubble time. We estimate to what extent this process could contribute to the mass of the super-massive black holes (SMBHs) observed in galactic centres today. The relation between SMBH and galactic bulge mass in our model displays the same slope as that found in observations. Many MBHs will not reach the centre of the host halo, however, but continue to orbit within it. In doing so MBHs may remain associated with remnants of the satellite halo systems of which they were previously a part. Using a semi-analytical approach that explicitly accounts for dynamical friction, tidal disruption and encounters with galactic disks, we follow the hierarchical merging of MBH systems and their subsequent dynamical evolution inside the respective host haloes. We predict the mass and abundance of MBHs in present-day galactic haloes, and also estimate the MBH mass accretion rates as well as bolometric luminosities for two different accretion scenarios. MBHs that have not undergone recent merging will retain associated dark matter cusps that were enhanced by black hole accretion growth, and may be possible sources of gamma rays via neutralino annihilations.

The Role of Protestant Missionaires in Mexico’s Indigenous Awakening
Creators: name: Gallaher, Carolyn
Publisher: name: American University

description: Protestantism has grown rapidly among Latin America’s indigenous population since the 1980s. Despite Protestantism’s attractiveness to indigenous people, the literature has historically regarded it as incompatible with indigenous culture. Recent scholarship has moved beyond this assertion, focusing instead on the complexities of conversion and the paradoxes associated with it. Most scholars now argue that Protestantism can be compatible with indigenous culture. It is unclear, however, how Protestant institutions came to have a compatible relationship with indigenous culture. Indeed, Protestant churches/clergy continue to eschew many of the practices associated with indigenous culture. In this paper I address this question by examining the work of Protestant missionaries. I choose missionaries as my point of analysis because they were crucial in establishing Protestantism in the region, and thus the base point from which it is defined, practiced, and altered. As a case study I examine mission work in Oaxaca, Mexico. I argue that missionaries have changed both their conversion strategies and tactics for dealing with indigenous traditions. These changes make it easier for indigenous people to convert to Protestantism without rejecting key parts of their culture, and in a few cases by even embracing it. I examine two conversion strategies—group targeting and church planting. I also analyze three tactics missionaries use to negotiate indigenous customs considered ‘pagan.’ I choose tequio, village fiestas, and language politics because they have historically been sources of conflict between converts and their Catholic neighbours.

description: Bophuthatswana livestock owners show a definite interest in commercial stock farming. A considerable number wish to make money from livestock, including cattle, and a greater demand for money will give rise to an increase in commercialisation. Auctions form the most important sales outlets for cattle, sheep and goats. Distances and relative prices are the main factors in determining the choice of marketing channels. The majority are indifferent regarding the ethnic background of middlemen. Firms with tribal names will be popular, although Most livestock owners indicate indifference in this regard. Grading, weighing and feedlot fattening will be acceptable to most farmers. When selling animals, farmers wish to receive prompt and quick payment. These factors warrant careful attention when planning future meat marketing bodies.

description: In the $Λ$CDM scenario, small galaxies merge to produce larger entities. Since supermassive black holes (SMBHs) are found in galaxies of all sizes, SMBH binaries (SMBHBs) are generally expected to form during the amalgamation of galaxies. It is unclear what fraction of these binaries could eventually merge, but a general consensus is that initially the orbital decay is mediated by the surrounding gas and stars. In this Letter, we show that in active galactic nulcei (AGNs) the radiation field also causes the orbits of the accreting SMBHs to shrink. The corresponding mechanism, known as the "Poynting-Robertson drag" (PR drag), takes effect on a well-defined timescale $CT_{\rm Sal}$, where $T_{\rm Sal}$ is the Salpeter timescale of the AGN, presumably coincide with the primary SMBH, and $C=4ξ^{-1}ε^{-1}q^{1/3}(1+q)^{2/3}(1-ε)$ is a constant determined by the radiative efficiency $ε$, the mass ratio $q$ of the two black holes, and a parameter $ξ$ characterizing the size of the circum-secondary accretion disk. We find that when $q\lesssim$a few$\times10^{-5}$, the PR drag is more efficient in shrinking the binary than many other mechanisms, such as dynamical friction and type-I migration. Our finding points to a possible new channel for the coalescence of unequal SMBHBs and the clearing of intermediate-massive black holes in AGNs.
