description: Temperature is a crucial parameter in circumstellar disk evolution and planet formation, because it governs the resistance of the gas to gravitational instability and sets the chemical composition of the planet-forming material. We set out to determine the gas temperature of the young disk-like structure around the Class 0 protostar IRAS 16293$-$2422A. We use Atacama Large Millimeter/submillimeter Array (ALMA) observations of multiple H$_2$CS $J=7-6$ and $J=10-9$ lines from the Protostellar Interferometric Line Survey (PILS) to create a temperature map for the inner $\sim$200 AU of the disk-like structure. This molecule is a particularly useful temperature probe because transitions between energy levels with different $K_{\rm{a}}$ quantum numbers operate only through collisions. Based on the H$_2$CS line ratios, the temperature is between $\sim$100$-$175 K in the inner $\sim$150 AU, and drops to $\sim$75 K at $\sim$200 AU. At the current resolution (0.5$^{\prime\prime} \sim$70 AU), no jump is seen in the temperature at the disk-envelope interface. The temperature structure derived from H$_2$CS is consistent with envelope temperature profiles that constrain the temperature from 1000 AU scales down to $\sim$100 AU, but does not follow the temperature rise seen in these profiles at smaller radii. Higher angular resolution observations of optically thin temperature tracers are needed to establish whether cooling by gas-phase water, the presence of a putative disk or the dust optical depth influences the gas temperature at $\lesssim$100 AU scales. The temperature at 100 AU is higher in IRAS 16293A than in the embedded Class 0/I disk L1527, consistent with the higher luminosity of the former.

Planning by Design : Applying design thinking to municipal planning
Creators: name: Roe, Jean
Publisher: name: The University of British Columbia
Year: 2020

description: This research explores how design thinking can generally be applied to municipal policymaking. More specifically, it explores how a sprint methodology—a three to five day intensive workshop that employs design thinking—may be applied to the municipal planning process. As the challenges facing our cities become more uncertain and complex, local governments must respond to urgent and ever-adapting demands. The recent onset of the COVID-19 pandemic has drastically increased the uncertainty and complexity of the modern world. The structure of bureaucratic organizations—which were built for a different reality in past centuries—inhibits the ability for municipal planners to keep up with complex, ever-changing challenges. Design thinking offers a set of processes, tools and methods that can help public servants respond to such problems. It can also help maintaain a focus on empathizing with citizens, which can easily get lost in the ‘churn’ of typical planning processes. Through an extensive literature review and interviews with 27 planners and designers, the research revealed four key insights.

title: The Role of Complement in Antibody-Dependent Acquired Immunity to Plasmodium falciparum Malaria
Creators: name: Kiyuka, Patience Kerubo
Publisher: name: The Open University
Year: 2020

description: Many pathogens evade complement recognition by binding to complement regulatory proteins, such as factor H (FH), that protect host cells from complement attack. Asexual Plasmodium falciparum stages evade complement destruction by capturing FH on their surface. An initial study identified Pf92 as the only protein that interacts with FH; however, the Pf92 knockout transgenic parasites did not wholly abolish FH recruitment to the merozoite. Thus, I hypothesized that potentially, more merozoite proteins are involved in complement evasion.

 I used a combination of modified ELISA binding assay and surface plasmon resonance and tested a library of 110 recombinant merozoite proteins for interaction with FH. Protein microarray was used to measure antibody responses to the merozoite antigens that interacted with FH in a malaria longitudinal cohort of children. Additionally, I tested whether circulating levels of FH and the Y402H variant in the FH gene influence malaria severity.

 In addition to Pf92, I found seven additional merozoite proteins that interact with the FH, i.e. PF3D7_1105800, PF3D7_0206200, RH5, P12, PF3D7_1252300, PF3D7_0629500 (SEG) and P12p. Majority of the proteins bound to complement control protein modules (CCP) 5-7 of FH. Antibody responses against a combination of some of these merozoite FH receptor antigens were found to be associated with protective immunity. Children with severe malaria (SM) had markedly lower circulating FH levels compared to uncomplicated malaria (UM) controls (median: SM=269 ug/ml, UM=378 ug/ml, P=<0.0001). Besides, children homozygous for the Y402H variant had a slightly increased risk of severe malaria (OR 1.08 95% CI: 0.46-2.58 P=0.854) while those who were heterozygous had reduced risk (OR 0.62 95% CI: 0.30-1.28 P=0.195) when compared with normal individuals.

 These findings suggest that the Plasmodium falciparum parasite uses many proteins to interact with FH to avoid complement destruction and that FH protein, could be a vital host determinant for malaria severity. This study offers insights into the mechanisms of malaria parasite complement immune evasion and provides a rationale for future studies to evaluate stage-specific parasite proteins for interaction with complement regulatory proteins.

description: NGC5018, one of the weakest UV emitters among giant ellipticals (gE) observed with IUE, appears to consist of an optical stellar population very similar to that of the compact, dwarf elliptical M32, which is several magnitudes fainter in luminosity than NGC5018 and whose stellar population is know to be ~3 Gyr old. Here we show that the mid-UV spectra of these two galaxies are also very similar down to an angular scale hundreds times smaller than the IUE large aperture (as probed by HST/FOS UV spectra obtained through 0.86 arcsec apertures). This implies a reasonably close match of the populations dominating their mid-UV light (namely, their main-sequence turnoff stars). These data indicate that NGC5018 has, in its inner regions, a rather uniform dominance of a ~3 Gyr-old stellar population, probably a bit different in metallicity from M32. Combined with the various structures that indicate that NGC5018 is the result of a recent major merger, it appears that almost all of stars we see in its center regions were formed about 3 Gyr ago, in that merger event. NGC5018 is likely the older brother of NGC7252, the canonical gE-in-formation merger. As such, NGC5018 is perhaps the best galaxy which can tell us how a merger works, after the fireworks subside, to form a gE galaxy today. For this reason alone, the stellar populations in NGC5018 at all radii are worth studying in detail.

description: Recently, the discovery of the radial acceleration relation (RAR) in galaxies has been regarded as an indirect support of alternative theories of gravity such as Modified Newtonian Dynamics (MOND) and modified gravity. This relation indicates a tight correlation between dynamical mass and baryonic mass in galaxies with different sizes and morphology. However, if the RAR relation is scale-independent and could be explained by alternative theories of gravity, this relation should be universal and true for galaxy clusters as well. In this article, by using the x-ray data of a sample of galaxy clusters, we investigate if there exists any tight correlation between dynamical mass and baryonic mass in galaxy clusters, assuming hot gas mass distribution almost representing baryonic distribution and that the galaxy clusters are virialized. We show that the resulting RAR of 52 non-cool-core galaxy clusters scatters in a large parameter space, possibly due to our simplifying assumptions and unclear matter content in galaxy clusters. This might indicate that the RAR is unlikely to be universal and scale-independent.

description: We present high-reflectivity mechanical resonators fabricated from AlGaAs heterostructures for use in free-space optical cavities operating in the telecom wavelength regime. The mechanical resonators are fabricated in slabs of GaAs and patterned with a photonic crystal to increase their out-of-plane reflectivity. Characterization of the mechanical modes reveals residual tensile stress in the GaAs device layer. This stress results in higher mechanical frequencies than in unstressed GaAs and can be used for strain engineering of mechanical dissipation. Simultaneously, we find that the finite waist of the incident optical beam leads to a dip in the reflectance spectrum. This feature originates from coupling to a guided resonance of the photonic crystal, an effect that must be taken into account when designing slabs of finite size. The single- and sub-$\upmu$m-spaced double-layer slabs demonstrated here can be directly fabricated on top of a distributed Bragg reflector mirror in the same material platform. Such a platform opens a route for realizing integrated multi-element cavity optomechanical devices and optomechanical microcavities on chip.

description: Current evidence indicates that the pharmacokinetic profile of rivaroxaban is not significantly impacted by body weight. However, real-world data are needed to better assess the potential clinical benefits and risks associated with rivaroxaban in non-valvular atrial fibrillation (NVAF) patients with obesity. Thus, our objectives were to assess the real-world effectiveness and safety of rivaroxaban versus warfarin among NVAF patients with obesity in the US nationally representative commercially-insured population. Health insurance claims data from the IQVIA PharMetrics Plus database (January 2010–September 2019) were used to identify NVAF patients with obesity (based on diagnosis codes) initiated on rivaroxaban or warfarin. Inverse probability of treatment weighting (IPTW) was used to adjust for imbalances between groups. Study outcomes of interest were evaluated up to 36 months post-treatment initiation and included the composite of stroke or systemic embolism (stroke/SE) and major bleeding. Outcomes were compared using Cox proportional hazards regression models with hazard ratios (HR) and 95% confidence intervals (CIs). A total of 10,555 patients were initiated on rivaroxaban and 5080 patients on warfarin. Following IPTW, the risk of stroke/SE was 26% lower among patients prescribed rivaroxaban relative to warfarin (HR: 0.74, 95% CI: 0.60, 0.91, p = .004) at 36 months. Rivaroxaban-initiated patients had a risk of major bleeding similar to that of warfarin-initiated patients (HR: 0.85, 95% CI: 0.71, 1.02, p = .085). These results suggest that rivaroxaban is an effective and safe treatment option among NVAF patients with obesity in a commercially-insured US population.

The first library cycle implements basic geometric operations on cycles, which are the zero sets of certain polynomials of degree two. The second library figure operates on ensembles of cycles interconnected by Moebius-invariant relations: orthogonality, tangency, etc. Both libraries work in spaces with any dimension and arbitrary signatures of their metrics. Their essential functionality is accessible in interactive modes from Python/Jupyter shells and a dedicated Graphical User Interface. The latter does not require any coding skills and can be used in education. The package is tested on (and supplied for) various Linux distributions, Windows 10, Mac OS X and several cloud services.

title: Ford Madox Ford's Anglo-German Ambivalence: Authoring Propaganda and Negotiating Nationalism as a Literary Cosmopolitan
Creators: name: Borkett-Jones, Lucinda Carys
Publisher: name: The Open University
Year: 2019

description: This thesis aims to analyse and reintegrate Ford Madox Ford’s Anglo-German identity into the biographical and critical narrative of his work. I concentrate on Ford’s writing during the First World War, the period when, critics suggest, his views on Germany changed because of his involvement with the British propaganda campaign and his subsequent decision to enlist in the British Army. Throughout the first year of the war, Ford wrote for the Outlook, a weekly review of politics and the arts. This is the first detailed study of these articles and, as such, it contributes to our understanding of Ford’s experience of the war before enlisting, as well as his wider journalism. Analysing Ford’s Outlook articles alongside his propaganda books provides an important corrective to a singular focus on the propaganda as Ford’s literary response to life on the home front. Combining archival research and literary analysis of his unpublished manuscripts, correspondence, and some lesser-known works, I argue that Ford neither loved Germany before the war as much as has sometimes been portrayed, nor hated it afterwards as much as is often assumed. Ford’s mixed cultural heritage constitutes an important part of his personal and literary identity and contributes to his ambivalent aesthetic. Through comparison with his contemporaries, and exploration of the complexities of broader Anglo-German relations, I suggest that Ford gave expression to feelings that were more widespread among propagandists than is usually acknowledged. I see Ford’s ambivalence as an asset rather than a mark of indecision, a distinctive feature resulting from his dual cultural heritage, which fuelled his revived cosmopolitanism in the post-war period, and which had both a social and artistic function.

description: In 2012, Migliore, the first author, and Nagel conjectured that, for all $n\geq 4$, the artinian ideal $I=(L_0^d,\ldots,L_{2n+1}^d) \subset R=k[x_0,\ldots,x_{2n}]$ generated by the $d$-th powers of $2n+2$ general linear forms fails to have the weak Lefschetz property if and only if $d>1$. This paper is entirely devoted to prove partially this conjecture. More precisely, we prove that $R/I$ fails to have the weak Lefschetz property, provided $4\leq n\leq 8,\ d\geq 4$ or $d=2r,\ 1\leq r\leq 8,\ 4\leq n\leq 2r(r+2)-1$.

title: Addressing Ethical Issues for Health and Demographic Surveillance Systems in Sub-Saharan Africa
Creators: name: Hinga, Alex Nginyo
Publisher: name: The Open University
Year: 2020

description: In this thesis, I discuss ethical issues for health and demographic surveillance systems (HDSS). HDSS involve the longitudinal monitoring of vital events, such as births and deaths, in a relatively small, geographically defined population, without a specified end date. Methodologically and in their aims, HDSS occupy a grey area between research, health care and public health. Despite involving millions of people in sub-Saharan Africa and other settings that face significant health and socioeconomic challenges, HDSS have received little attention in the empirical ethics literature and guidelines. To address the empirical and normative gaps in HDSS ethics, I conducted a qualitative study based on a case study design. This included three interlinked phases; 1) formative research in six HDSS across sub-Saharan Africa to map out key ethical issues 2) a case study of two HDSS in Kenya to explore ethical issues in depth, 3) an assessment of the wider relevance of the case study findings. I explored the views and experiences of HDSS research and community stakeholders through interviews, observations, document reviews and focus group discussions. I drew on this empirical data, and the wider bioethics and social science literature to develop normative conclusions on HDSS ethics. Overall, the benefits and burdens of HDSS appear disproportionately distributed among stakeholders. Verbal autopsy respondents and interviewers bear most of the severe burdens in HDSS, with significant emotional and moral distress respectively. HDSS residents are also exposed to a wide range of risks (such as to privacy) regularly over a long timescale. Although HDSS have contributed to scientific publications which could inform policy and practice, this potential social value, as well as more immediate local benefits, are not well-articulated or demonstrated in practice. I make recommendations to minimise burdens and enhance the social value of HDSS in sub-Saharan Africa.

description: This study uses a unique combination of State panel data and qualitative interviews to examine the economic and policy factors associated with the sharp increase in the number of Food Stamp Program (FSP) participants between 2000 and 2006. This period is particularly interesting because the rise in participation between 2003 and 2006 occurred while the national economy was improving. Higher numbers of participants were associated with higher State unemployment rates and lower State labor force participation rates and minimum wages. The introduction of FSP policies designed to expand eligibility and ease reporting also increased the number of participants. In addition, program outreach efforts were associated with higher caseloads in times of low unemployment. Interviews with State FSP administrators and staff at community-based organizations reinforce the quantitative findings and point to declining local economic conditions and high-quality program outreach as the main sources of caseload growth. The Food Stamp Program was renamed the Supplemental Nutrition Assistance Program (SNAP) in October 2008.

description: In a recent paper [Phys. Rev. Lett. 111, 100501 (2013)], a scheme was proposed where subsequent observers can extract unambiguous information about the initial state of a qubit, with finite joint probability of success. Here, we generalize the problem for arbitrary preparation probabilities (arbitrary priors). We discuss two different schemes: one where only the joint probability of success is maximized and another where, in addition, the joint probability of failure is also minimized. We also derive the mutual information for these schemes and show that there are some parameter regions for the scheme without minimizing the joint failure probability where, even though the joint success probability is maximum, no information is actually transmitted by Alice.

description: Helicopter operations from warships are an integral part of the primary and secondary roles of the vessel. The future warships are being designed with increasing importance on stealth and operate multiple types of maritime helicopter and unmanned aerial vehicles. The flow dynamics on the helodeck of these ships is significantly different from older generation warships. Presently there are no design tools for optimization of the dynamic flow conditions on the helodeck during initial design. This poses a significant challenge to the designer as well as the operator. The operability of helicopters from warships is verified during later stages of warship construction by Experimental Test Pilots (ETPs), performing high-risk trials. The expensive, time-consuming Ship Helicopter Operating Limits (SHOL) trials undertaken by ETPs additionally render the warships unavailable for operational requirements for significant time period after the commissioning of the warship.
It is understood that the coupled effects of ship airwake and helicopter rotor downwash are not a direct superposition ofthe flows. This paper examines numerically the effects of Simplified Helicopter Rotor Downwash (SRD) interacting with a ROBIN (ROtor Body INteraction) fuselage and ship airwake for a Simplified Frigate Ship (SFS2). Flow visualization and measurements have been undertaken to generate data for numerical study validation. These results were further used to investigate the suitability of steady RANS solutions for numerical modelling of the dynamic flow conditions using commercial code – ANSYS Fluent. Parametric analysis carried out to investigate the interaction of varying helicopter operations at different warship speed regimes are discussed. The effect on the fuselage was extended to estimate the increased pilot-workload and decreased operational availability at multiple velocity ratios of the ship and helicopter downwash. The results analysis discusses the effect of the coupled flow dynamics in terms of effects on the recirculation region, rotor plane wake and turbulence intensity across the helicopter fuselage. This methodology can be used as a preliminary design tool for varying ship/helo configurations for safe aviation facilities.

description: This study examines the economic coping strategies of low-income families, using data collected through qualitative interviews conducted in 2006-08 with 35 low-income women residing in the Detroit metropolitan area. Three rounds of interviews found that the majority of the sample were employed at least some of the time, and most had children living with them. Despite careful shopping practices, rising food prices forced cutbacks in purchase of certain foods, including milk, cereal, fruits, and meat. Just under half reported running out of food at some point during the year. As for government assistance, the then named Food Stamp Program, and now called the Supplemental Nutrition Assistance Program (SNAP), was their mainstay. Even when eligible for benefits, many of the families did not receive cash assistance, unemployment benefits, or workers’ compensation due to perceived access barriers.

description: The reliability of mobile devices is a challenge for vendors, since the mobile software stack has significantly grown in complexity. In this paper, we study how to assess the impact of faults on the quality of user experience in the Android mobile OS through fault injection. We first address the problem of identifying a realistic fault model for the Android OS, by providing to developers a set of lightweight and systematic guidelines for fault modeling. Then, we present an extensible fault injection tool (AndroFIT) to apply such fault model on actual, commercial Android devices. Finally, we present a large fault injection experimentation on three Android products from major vendors, and point out several reliability issues and opportunities for improving the Android OS.

description: We decompose various quark-gluon Fock states of a nucleon in a set of states in which each of the three-quark core and the rest of the stuff, termed as a sea, appears with definite spin and color quantum number, their weight being determined, statistically, from their multiplicities. The expansion coefficients in the quark-gluon Fock states have been taken from a recently proposed statistical model. We have also considered two modifications of this model with a view to reduce the contributions of the sea components with higher multiplicities. With certain approximations, we have calculated the quark contributions to the spin of the nucleon,the ratio of the magnetic moments of nucleons, their weak decay constant, and the ratio of SU(3) reduced matrix elements for the axial current. A reasonably close agreement with the corresponding experimental values have been obtained in all the three cases.

description: Dusty star-forming galaxies (DSFGs) detected at $z > 4$ provide important examples of the first generations of massive galaxies. However, few examples with spectroscopic confirmation are currently known, with Hershel struggling to detect significant numbers of $z > 6$ DSFGs. NGP6_D1 is a bright 850 $μm$ source (12.3 $\pm$ 2.5 mJy) with no counterparts at shorter wavelengths (a SPIRE dropout). Interferometric observations confirm it is a single source, with no evidence for any optical or NIR emission, or nearby likely foreground lensing sources. No $>3σ$ detected lines are seen in both LMT RSR and IRAM 30m EMIR spectra of NGP6_D1 across 32 $GHz$ of bandwidth despite reaching detection limits of $\sim 1 mJy/500 km~s^{-1}$, so the redshift remains unknown. Template fitting suggests that NGP6_D1 is most likely between $z = 5.8$ and 8.3. SED analysis finds that NGP6_D1 is a ULIRG, with a dust mass $\sim 10^8$ - $10^9$ $M_{\odot}$ and a SFR of $\sim$ 500 $M_{\odot}~yr^{-1}$. We place upper limits on the gas mass of NGP6_D1 of $M_{H2}$ $ < (1.1~\pm~3.5) \times 10^{11}$ $M_{\odot}$, consistent with a gas-to-dust ratio of $\sim$ 100 - 1000. We discuss the nature of NGP6_D1 in the context of the broader submm population, and find that comparable SPIRE dropouts account for $\sim$ 20% of all SCUBA-2 detected sources, but with a similar flux density distribution to the general population.

title: Gesture in multimodal language learner interaction via videoconferencing on mobile devices
Creators: name: Lee, Helen
Publisher: name: The Open University
Year: 2020

description: This thesis focuses on how adult English language learners exploit and experience gesture while communicating with one another via mobile technologies. Mobiles create opportunities for multimodal language learning beyond the classroom (Kukulska-Hulme et al., 2017), however, modes such as gesture are mediated and transformed by technology in complex ways (Hampel & Stickler, 2012). In a small-scale qualitative study, learners from a range of nationalities who were studying on language programmes in the UK were connected in dyads via Skype videoconferencing (VC) in order to complete information gap tasks using tablets, 2-in-1 devices, and smartphones. These communicative tasks had been intentionally designed around a diversity of informal ‘settings’ (Benson, 2011) which included cafés, museums, and historical buildings. Following the tasks, participants took part in stimulated recall interviews in order to reflect on their multimodal forms of communication.

 This exploratory, qualitative study examines gesture from a theoretical perspective which links the mode to spoken language (Kendon, 2004; McNeill, 1992; Norris, 2004) and positions gesture within the wider framework of the negotiation of meaning (Varonis & Gass, 1985). As the role of speech-associated gestures within language learning via technology has not been widely researched, an interdisciplinary methodology had to be designed to analyse the video recorded data from the learners’ tasks. This is based on transcription procedures from gesture-speech analysis (McNeill, 1992; McNeill & Duncan, 2000). As gesture in this study is understood as being closely aligned to speech, a multimodal unit of analysis was combined with the Varonis and Gass (1985) framework of the negotiation of meaning. The multimodal method allowed for the categorisation and analysis of gesture to investigate how learners may co-orchestrate the two modes in relationship to their deployment of mobile technologies from beyond the classroom. The participants were asked to reflect on their interactions from multimodal perspectives and interview data were triangulated with the task performances. Theoretical and pedagogical conclusions are drawn as to the manner in which learners exploit gesture as an integral part of the negotiation of meaning.

description: We observed the pre-stellar core L1521F in dust emission at 1.2mm and in two transitions each of N2H+, N2D+, C18O, and C17O in order to increase the sample of well studied centrally concentrated and chemically evolved starless cores, likely on the verge of star formation, and to determine the initial conditions for low--mass star formation in the Taurus Molecular Cloud. We derived in this object a molecular hydrogen number density n(H2) ~ 10^6 cm-3 and a CO depletion factor, integrated along the line of sight, fD ~ 15 in the central 20'', similar to the pre-stellar core L1544. However, the N(N2D+)/N(N2H+) column density ratio is ~0.1, a factor of about 2 lower than that found in L1544. The observed relation between the deuterium fractionation and the integrated CO depletion factor across the core can be reproduced by chemical models if N2H+ is slightly (factor of ~2 in fractional abundance) depleted in the central 3000 AU. The N2H+ and N2D+ linewidths in the core center are ~0.3 km/s, significantly larger than in other more quiescent Taurus starless cores but similar to those observed in the center of L1544. The kinematical behaviour of L1521F is more complex than seen in L1544, and a model of contraction due to ambipolar diffusion is only marginally consistent with the present data. Other velocity fields, perhaps produced by unresolved substructure, are present. Both chemical and kinematical analyses suggest that L1521F is less evolved than L1544, but, in analogy with L1544, it is approaching the ``critical'' state.

Free-floating bike share as a last mile transit connection : using hazard models to understand bike share patterns at UBC
Creators: name: Vissers, M. Jake
Publisher: name: The University of British Columbia
Year: 2020

description: The University of British Columbia (UBC) launched its first permanent free-floating bike share (FFBS) in 2019 with the arrival of HOPR. This new system is part of a global trend which has seen FFBS grow significantly in the last five years. As such, exploring how this emerging technology is being used has become more critical in planning for existing and future systems. Existing literature shows that proximity to transit can increase demand for FFBS, suggesting that FFBS may be an effective first/last mile connection. The purpose of this study is to determine whether proximity to frequent transit increases FFBS demand at UBC. To do this, I examine how ambient factors, such as weather, land use and transit, among others, affect bicycle idle duration, which I use as an inverse proxy for demand. This is done by estimating a Cox proportional hazard model, which models how each covariate affects the probability of a bicycle being booked. This study offers a unique exploration of how FFBS is used on a major university campus, particularly whether the system serves as a last mile connection for transit. These findings may benefit future planning decisions at UBC, as well as other universities interested in FFBS.

description: The ship-helicopter combined operation poses a significant workload even for the most experienced test pilots. The main reason for this workload is the complex turbulent airwake over the helodeck. The occurrence of such complex airwake significantly alters the helicopter aerodynamics during launch and recovery operation. A numerical investigation has been performed with NASA ROtor Body INteraction (ROBIN) helicopter fuselage and TTCP Simple Frigate Ship 2 (SFS2) geometry to study the combine ship-helo airwake aerodynamics. A parametric study has been conducted at different wind-over-deck (WOD) azimuth and fuselage orientations with steady Reynolds-averaged Navier-Stokes (RANS) approach. Results are presented for a range of aerodynamic parameters. These results highlight the characteristics of force and moment experienced by the helicopter fuselage during ship-helicopter combined operation. It has been found that low oblique wind direction and small fuselage yaw would be favourable to limit the pilot workload for ship-helicopter dynamic interface.

description: The Supplemental Nutrition Assistance Program (SNAP), formerly known as the Food Stamp Program (FSP), provides low-income households with electronic benefits that can be used to purchase food in grocery stores and supermarkets. People residing on Indian reservations, and households with American Indians and Alaska Natives residing off but near reservations, or in certain areas of Oklahoma, may have a food assistance option besides SNAP/FSP—the Food Distribution Program on Indian Reservations (FDPIR), which provides a monthly package of commodities. FDPIR was established, in part, to address concerns about the distances some reservation residents would have to travel to SNAP/FSP offices and grocery stores in order to obtain and use food stamps. Eligibility requirements for FDPIR are similar, but not identical, to those for SNAP/FSP. FDPIR households cannot participate in both FDPIR and SNAP/FSP in the same month, so those who are eligible for both programs must choose between them. This report combines findings from site visits to seven reservations that participate in FDPIR with analysis of administrative and survey data to compare the two programs with regard to eligibility, participation, administration, and possible effects on health and nutrition. Results show that FDPIR benefits some American Indian and Alaska Native households that are not eligible for SNAP/FSP. Simulation estimates suggest that in an average month, 13 percent of households eligible for FDPIR would not be eligible for SNAP/FSP. Another 41 percent of the households eligible for FDPIR are eligible for SNAP/FSP but would receive FDPIR commodities with retail value above the SNAP/FSP benefit. The remaining 46 percent of households eligible for FDPIR are eligible for SNAP/FSP and would receive more benefits from that program than from FDPIR. What determines the choice between programs, among people who have a choice? The size of the benefit for which the household would qualify is certainly a factor, but administrators and participants suggest that the ease of enrollment, cultural compatibility, choice in food selection, and access to grocery stores also appear to affect participation decisions.
