description: The paper proposes the use of green IT as a tool for designing a cloud-oriented sustainable learning environment for a higher education institution. The article substantiates the expediency of designing such an environment as a prerequisite for the sustainable development of Ukraine. It is established that one of the goals of Ukraine's sustainable development for 2030 is to provide fair quality education and to promote lifelong learning opportunities for all. Green IT is a set of approaches related to sustainable computing and information technology. The work of foreign scientists was analyzed, which considered the issues of designing the learning environment using green computing. As a result, Cloud LMS has been established that cloud LMS is a type of green IT and can serve as a tool for designing a cloud-oriented sustainable learning environment of a higher education institution. A model of a cloud-oriented sustainable learning environment of a higher education institution using cloud LMS is proposed. The application of a cloud-oriented sustainable learning environment will provide such capabilities: keep electronic journals; use on-line services; conduct correspondence, assessment of knowledge on-line; and more. And all of the above is the key to a sustainable development of the learning environment.

description: We use Wetterich's parameterization equation of state (EOS) of dark energy to a $5D$ Ricci-flat cosmological solution and we suppose the universe contains three major components: matter, radiation and dark energy. By using the relation between the scale factor and the redshift $z$, we show that the two arbitrary functions contained in the $5D$ solution could be solved out analytically in terms of the variable $z$. Thus the whole $5D$ solution could be constructed uniquely if the current values of the three density parameters $Ω_{m0}$, ${Ω_{r0}}$, $Ω_{x0}$, the EOS $w_{0}$%, and the bending parameter $b$ contained in the EOS are all known. Furthermore, we find that all the evolutions of the mass density $Ω_{m} $, the radiation density ${Ω_{r}}$, the dark energy density $Ω_{x}$, and the deceleration parameter $q$ depend on the bending parameter $b$ sensitively. Therefore it is deserved to study observational constraints on the bending parameter $b$.

description: Knowledgebase question answering systems are heavily dependent on relation extraction and linking modules. However, the task of extracting and linking relations from text to knowledgebases faces two primary challenges; the ambiguity of natural language and lack of training data. To overcome these challenges, we present SLING, a relation linking framework which leverages semantic parsing using Abstract Meaning Representation (AMR) and distant supervision. SLING integrates multiple relation linking approaches that capture complementary signals such as linguistic cues, rich semantic representation, and information from the knowledgebase. The experiments on relation linking using three KBQA datasets; QALD-7, QALD-9, and LC-QuAD 1.0 demonstrate that the proposed approach achieves state-of-the-art performance on all benchmarks.

The lived experience of recovery from sexual abuse for young adult women
Creators: name: Crandall, Joanne Margaret
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study was to provide an in-depth description of the lived experience of recovery for young adult women who had been sexually abused as children. Nine women participated in the study. In order to be a part of the study, the women were between the ages of 16 and 25 at the time of the first interview, and had been sexually abused before the age of 12 by a family member. Family members could include parents, step-parents, siblings, step-siblings, grandparents, aunts, uncles, and cousins. The sexual abuse must have been repetitive in nature and lasted for a period of 6 months or longer. The women had also participated in some type of therapy, for at least 6 months, where sexual abuse was the primary focus. As well, the women had some awareness that they were in recovery and were able to talk about their own experience of recovery. The interviews and the data analysis followed a phenomenological approach. The researcher conducted four interviews with each participant over a twenty month period. Ten common themes representing the lived experience of recovery from sexual abuse for young adult women emerged. The lived experience of recovery (1) involves working through the denial of being sexually abused, (2) diminishes the lasting effects of sexual abuse, (3) helps the person move from a victim stance to a survivor stance, (4) is a journey of self-discovery, (5) fosters the possibility for improved relationships with family members, friends, and partners, (6) reduces the negative influence of the perpetrator, (7) encompasses a variety of therapeutic encounters, (8) helps the person to explore the ambiguity of memory, (9) influences future direction, and (10) is a complex process with no clear resolution. The descriptions of each theme illustrate how the women were able to confront and transform the trauma of being sexually abused. The findings of this study describe how young adult women perceive the lived experience of recovery and illuminate what needs to take place so that recovery is possible. The lived experience of recovery is an interactive phenomenon which requires the women to explore the meaning of recovery both intrapersonally and interpersonally. As the women's thoughts, perceptions, beliefs, feelings, and expectations change internally, the ways in which they interact with the world around them shift as well. The lived experience of recovery is both complex and perplexing. The findings from this study offer recommendations for counselling research and practice in the area of sexual abuse for young adult women.

description: Using the method of noncommutative geometry, we define a topological invariant in disordered bosonic Bogoliubov-de Gennes systems, which possess a unique mathematical property---non-Hermiticity. To demonstrate the validity of the definition, we investigate a disordered artificial spin ice model in two dimensions numerically. In the clean limit, we clarify that the topological index perfectly coincides with the Chern number. We also show that the topological index is robust against disorder. The formula provides the topological index $n_{\rm Ch}=1$ in the magnon Hall regime and $n_{\rm Ch}=0$ in a trivial localized one. We also show by example that our method can be extended to other symmetry classes. Our results pave the way for further studies on topological bosonic systems with disorder.

Subjects: convective burst
hurricane
lightning

description: Hurricane intensification can be broadly related to three physical processes: 1) large-scale environmental influences, 2) mesoscale internal dynamics, and 3) convective scale interactions. These processes may act individually or collectively and all three may be important at different times in a storm's lifecycle. Hurricane Earl 2010 had near-continuous flight coverage observing multiple convective bursts prior to and during the period of rapid intensification. The storm was very energetic and electrified with lightning present in both the eyewall and outer rainbands during the strong convective bursts, which helped in assessing convective vigor.  Important environmental conditions that were favorable for intensification of Earl involved weak vertical wind shear, steady warm SSTs, and high OHC. Analysis focuses on the internal storm relationships such as (1) long-lived, intense clusters of convection, (2) associated lightning activity and (3) the establishment of the storm's warm core in the middle and upper troposphere.

description: Context: Sticking of colliding dust particles through van der Waals forces is the first stage in the grain growth process in protoplanetary disks, eventually leading to the formation of comets, asteroids and planets. A key aspect of the collisional evolution is the coupling between dust and gas motions, which depends on the internal structure (porosity) of aggregates. Aims: To quantify the importance of the internal structure on the collisional evolution of particles, and to create a new coagulation model to investigate the difference between porous and compact coagulation in the context of a turbulent protoplanetary disk. Methods: We have developed simple prescriptions for the collisional evolution of porosity of grain-aggregates in grain-grain collisions. Three regimes can then be distinguished: `hit-and-stick' at low velocities, with an increase in porosity; compaction at intermediate velocities, with a decrease of porosity; and fragmentation at high velocities. (..) Results: (..) We can discern three different stages in the particle growth process (..) We find that when compared to standard, compact models of coagulation, porous growth delays the onset of settling, because the surface area-to-mass ratio is higher, a consequence of the build-up of porosity during the initial stages. As a result, particles grow orders of magnitudes larger in mass before they rain-out to the mid-plane. Depending on the turbulent viscosity and on the position in the nebula, aggregates can grow to (porous) sizes of ~ 10 cm in a few thousand years. We also find that collisional energies are higher than in the limited PCA/CCA fractal models, thereby allowing aggregates to restructure. It is concluded that the microphysics of collisions plays a key role in the growth process.

description: The international trade is one of the classic areas of study in economics. Nowadays, given the availability of data, the tools used for the analysis can be complemented and enriched with new methodologies and techniques that go beyond the traditional approach. The present paper shows the application of the Latent Dirichlet Allocation Models, a well known technique from the area of Natural Language Processing, to search for latent dimensions in the product space of international trade, and their distribution across countries over time. We apply this technique to a dataset of countries' exports of goods from 1962 to 2016. The findings show the possibility to generate higher level classifications of goods based on the empirical evidence, and also allow to study the distribution of those classifications within countries. The latter show interesting insights about countries' trade specialisation.

description: The purpose of the present experiment was to investigate whether, with vision, the magnitude of the effect of calf muscles fatigue on postural control during bipedal quiet standing depends on the eye-visual target distance. Twelve young university students were asked to stand upright as immobile as possible in three visual conditions (No vision, Vision 1m and Vision 4m) executed in two conditions of No fatigue and Fatigue of the calf muscles. Centre of foot pressure displacements were recorded using a force platform. Similar increased variances of the centre of foot pressure displacements were observed in the fatigue relative to the No fatigue condition for both the No vision and Vision 4m conditions. Interestingly, in the vision 1m condition, fatigue yielded: (1) a similar increased variance of the centre of foot pressure displacements to those observed in the No vision and Vision 4m conditions along the medio-lateral axis and (2) a weaker destabilising effect relative to the No vision and Vision 4m conditions along the antero-posterior axis. These results evidence that the ability to use visual information for postural control during bipedal quiet standing following calf muscles fatigue is dependent on the eye-visual target distance. More largely, in the context of the multisensory control of balance, the present findings suggest that the efficiency of the sensory reweighting of visual sensory cues as the neuro-muscular constraints acting on the subject change is critically linked with the quality of the information the visual system obtains.

description: Straight beams, rods and trusses are common elements in structural and mechanical engineering, but recent advances in additive manufacturing now also enable efficient freeform fabrication of curved, deformable beams and beam structures, such as microstructures, metamaterials and conformal lattices. To exploit this new design freedom for applications with nonlinear mechanical behavior, we introduce an isogeometric method for shape optimization of curved 3D beams and beam structures. The geometrically exact Cosserat rod theory is used to model nonlinear 3D beams subject to large deformations and rotations. The initial and current geometry are parameterized in terms of NURBS curves describing the beam centerline and an isogeometric collocation approach is used to discretize the strong form of the balance equations. Then, a nonlinear optimization problem is formulated in order to optimize the positions of the control points of the NURBS curve that describes the beam centerline, i.e., the geometry or shape of the beam. To solve the design problem using gradient-based algorithms, we introduce semi-analytical, inconsistent analytical and fully analytical approaches for calculation of design sensitivities. The methods are numerically validated and their performance is investigated, before the applicability and versatility of our 3D beam shape optimization method is illustrated in various numerical applications, including optimization of an auxetic 3D metamaterial.

description: My practice-based research involves the design of wearable technology for enhancing proprioceptive and tactile sensitivity. Haplós is a low-cost, portable device that applies vibrotactile patterns to the skin, can be incorporated in existing clothing and implements, and can be programmed and activated remotely. It is inspired by the Feldenkrais Method (Feldenkrais, 1972), a movement-based learning system for neuromuscular re-education. I conducted a series of public engagement events and workshops that demonstrate how users of Haplós felt their relationship to the environment - specifically, the ground - more clearly through the application of vibrotactile stimuli. This poster shows two drawings generated by one of the participants. The shaded areas represent portions of the back that the participant could feel in contact with the ground when lying down. After stimulating one side of their back with Haplós, most participants reported that they felt more of that side of their back clearly and in contact with the ground. I thus argue that as a technology for improving self-sensing, Haplós can also be understood as a technology for getting to know the environment more intimately. As Höök et al. (2015) note, “by increasing our body awareness through engaging in various forms of training, we can become more perceptive and aware in the physical world in which we live and act”.

description: We present 1-mm observations constructed from ALMA [Atacama Large (sub)Millimeter Array] data of SO$_2$, SO and KCl when Io went from sunlight into eclipse (20 March 2018), and vice versa (2 and 11 September 2018). There is clear evidence of volcanic plumes on 20 March and 2 September. The plumes distort the line profiles, causing high-velocity ($\gtrsim$500 m/s) wings, and red/blue-shifted shoulders in the line profiles. During eclipse ingress, the SO$_2$ flux density dropped exponentially, and the atmosphere reformed in a linear fashion when re-emerging in sunlight, with a "post-eclipse brightening" after $\sim$10 minutes. While both the in-eclipse decrease and in-sunlight increase in SO was more gradual than for SO$_2$, the fact that SO decreased at all is evidence that self-reactions at the surface are important and fast, and that in-sunlight photolysis of SO$_2$ is the dominant source of SO. Disk-integrated SO$_2$ in-sunlight flux densities are $\sim$2--3 times higher than in-eclipse, indicative of a roughly 30--50\% contribution from volcanic sources to the atmosphere. Typical column densities and temperatures are $N \approx (1.5 \pm 0.3) \times 10^{16}$ cm$^{-2}$ and $T \approx 220-320$ K both in-sunlight and in-eclipse, while the fractional coverage of the gas is 2--3 times lower in-eclipse than in-sunlight. The low level SO$_2$ emissions present during eclipse may be sourced by stealth volcanism or be evidence of a layer of non-condensible gases preventing complete collapse of the SO$_2$ atmosphere. The melt in magma chambers at different volcanoes must differ in composition to explain the absence of SO and SO$_2$, but simultaneous presence of KCl over Ulgen Patera.

description: Introduction: Cerebral autoregulation (CA) plays a fundamental role in the maintenance of adequate cerebral blood flow (CBF). CA monitoring, through direct and indirect techniques, may guide an appropriate therapeutic approach aimed at improving CBF and reducing neurological complications; so far, the role of CA has been investigated mainly in brain-injured patients. The aim of this study is to investigate the role of CA in non-brain injured patients. Methods: A systematic consultation of literature was carried out. Search terms included: “CA and sepsis,” “CA and surgery,” and “CA and non-brain injury.” Results: Our research individualized 294 studies and after screening, 22 studies were analyzed in this study. Studies were divided in three groups: CA in sepsis and septic shock, CA during surgery, and CA in the pediatric population. Studies in sepsis and intraoperative setting highlighted a relationship between the incidence of sepsis-associated delirium and impaired CA. The most investigated setting in the pediatric population is cardiac surgery, but the role and measurement of CA need to be further elucidated. Conclusion: In non-brain injured patients, impaired CA may result in cognitive dysfunction, neurological damage, worst outcome, and increased mortality. Monitoring CA might be a useful tool for the bedside optimization and individualization of the clinical management in this group of patients.
Single photon continuous variable quantum key distribution based on energy-time uncertainty relation

description: In previous quantum key distribution (QKD) protocols, information is encoded on either the discrete-variable of single-photon signal or continuous-variables of multi-photon signal. Here, we propose a new QKD protocol by encoding information on continuous-variables of a single photon. In this protocol, Alice randomly encodes her information on either the central frequency of a narrow-band single photon pulse or the time-delay of a broadband single photon pulse, while Bob randomly chooses to do either frequency measurement or time measurement. The security of this protocol rests on the energy-time uncertainty relation, which prevents Eve from simultaneously determining both frequency and time information with arbitrarily high resolution. In practice, this scheme may be more robust against various channel noises, such as polarization and phase fluctuations.

In addition to the neutralino of SUSY models, we considered other candidates (exotic scalars as well as particles in Kaluza-Klein and technicolour theories) with masses in the TeV region. Then one finds reasonable branching ratios to excited states. Thus the detection of the WIMP can be made not only by recoil measurements, but by measuring the de-excitation $γ$-rays as well.

The experience of international students : exploration through drawings and interviews
Creators: name: Ishii, Eriko
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study was to explore the nature of the international students' adjustment processes through drawings and in-depth interviews. A qualitative approach was used to guide the data collection and analysis. Data were collected through in-depth semi-structured interviews with a volunteer sample of five graduate international students. The interviews aimed to obtain accounts and drawings that describe their experiences of the initial period in Canada and present lives as well as their wishes for the future. Audio taped interviews were transcribed verbatim and analyzed based on the Empirical Phenomenological Psychological (EPP) method proposed by Karlsson (1993). The analysis was validated first by a fellow researcher, and secondly through validation interviews with the participants. The results revealed a number of common and unique themes that were grouped under the following three dynamics: emotional, external, and behavioural. The results suggest that international students experienced various challenges during the initial period of being in Canada, and these challenges resulted in feelings such as nervousness, fear, loneliness, feelings of inadequacy, feelings of invisibility , and excitement. Description of their present lives indicated that they had adjusted to and were comfortable with their new lives in Canada. These themes and each participant's story were visually depicted in their drawings. The implication of these results is that international students are likely to benefit from counselling interventions particularly in the beginning of their time in Canada. Counsellors may utilize drawings for advantages revealed in this study; drawings may enable counsellors to understand these students' experiences from the perspectives of these students and to transcend cultural barriers. Furthermore, the results highlight the importance of considering international students as individuals with strengths, and treating each individual's experience as unique while being aware of the common struggles many of these students face. Finally, this study encourages further research in order to broaden our understanding of international students' experiences.

description: We look for critical points with U(2) residual symmetry in 5-dimensional maximally supersymmetric gauged supergravity, by varying the embedding tensor, rather than directly minimizing the scalar potential. We recover all previously known vacua and we find four new vacua, with different gauge groups and cosmological constants. We provide the first example of a maximal supergravity model in $D \geq 4$ having critical points with both positive and vanishing cosmological constant. For each vacuum we also compute the full mass spectrum. All results are analytic.

description: Purpose: This study examined trends and predictors of state Medicaid nursing home users and expenditures from 1997 to 2007 to identify factors of interest to policy makers and government officials interested in rebalancing the nation's long-term care (LTC) system. Design and Methods: State-level data were collected from multiple data sources for each study year. Three separate regression analyses were conducted to examine the effects of socio-demographic, economic, supply, political and programmatic factors on the share of total Medicaid LTC expenditures devoted to nursing home care, rates of nursing home utilization, and rates of nursing home expenditures. Results: The nursing home share of total Medicaid LTC expenditures was positively associated with female labor force participation, and negatively associated with those aged 85 and over, Hispanics, Medicare home health users, Cash and Counseling programs, and democratic governors. Rates of nursing home utilization were positively associated with poverty rates, nursing home beds, and personal care state plan options, and negatively associated with spending on Medicaid home- and community-based services (HCBS). Rates of nursing home expenditures were positively associated with those aged 65 to 84, Hispanics, per capita incomes, nursing home beds, and Real Choice System Change grants, and negatively associated with female labor force participation, poverty rates, HCBS spending, and democratic governors. Implications: Factors that may be amenable to policy intervention aimed at rebalancing the nation's LTC system include nursing home supply restriction and Medicaid program policy. States that reduce bed capacity may experience lower rates of nursing home utilization and expenditures, and those that take advantage of flexible service delivery models like the personal care state plan option and/or the Cash and Counseling grant/demonstration program may experience greater success rebalancing their LTC systems.

description: Figure S1 Protein sequence and structural features of the H. bakeri sid-2 orthologue that is enriched in EVs compared to EV-depleted HES. A Amino acid alignment showing low sequence conservation between H. bakeri and C. elegans sid-2 orthologues (24.5 % sequence identity). Regions predicted by DeepTMHMM [35] to be signal peptide (19 % sequence identity), extracellular domain (11.4 % sequence identity), transmembrane helix (52.4 % sequence identity) and cytoplasmic domain (17.5 % sequence identity) are annotated for each sequence and detailed in the table on the right. AlphaFold 3 predicted structures for sid-2 orthologues from B H. bakeri and C C. elegans. Structures are coloured by the pLDDT confidence estimate, which is scored from 0-100 (100 = higher confidence) and color coded as follows: dark blue is very high (pLDDT > 90), cyan is confident (90 > pLDDT > 70), yellow is low (70 > pLDDT > 50), and orange is very low (pLDDT < 50). Predicted aligned error is shown for each structure, with dark green indicating likely proximity of residues.

description: We review some basic theorems on integrability of Hamiltonian systems, namely the Liouville-Arnold theorem on complete integrability, the Nekhoroshev theorem on partial integrability and the Mishchenko-Fomenko theorem on noncommutative integrability, and for each of them we give a version suitable for the noncompact case. We give a possible global version of the previous local results, under certain topological hypotheses on the base space. It turns out that locally affine structures arise naturally in this setting.

description: The historical and ethnographic study of Union Market, a public market complex in Northeast Washington, D.C., examines the impact of decline and redevelopment on the social dynamics at work there from the late 1920s to present day.  The social dynamics explored include the people, culture, and function of the market.  This research connects the processes of urban change and identities (per)formed in the market with access to public space.  People (per)form identities, regardless of intention, through such means as  their appearance, food choices, and activities.  These performances imbue space with sociocultural coding that tells others who and what belong there.  This coding as well as processes of urban change like gentrification shape the public in public spaces.  Who public includes matters because of the role these spaces play in defining communities and societal values.  The story of Union Market offers an in-depth look at how public is shaped and by whom, the role of food in defining the identities of people and places, and the choices that drive urban change.

description: The application of information technology in the era of big data and cloud computing has led to the trend of electronic payments through financial technology, or FinTech. One of the most popular FinTech applications in Indonesia is Go-Pay in the Gojek start-up application. This research will analyze how the FinTech Go-Pay user experience both for transactions on Gojek and at merchants that collaborate with Gojek. User Experience (UX) is analyzed using the User Experience Questionnaire which consists of 6 (six) variables (Attractiveness, Perspicuity, Efficiency, Dependability, Stimulation, and Novelty). Total data collected amounted to 258. After analyzing the calculation results, the mean scores are obtained in the following order: Efficiency, Perspicuity, Stimulation, Attractiveness, Dependability, and Novelty. Then when compared with benchmark data the following sequence is obtained: Efficiency, Perspicuity, Stimulation, Attractiveness, Dependability, and Novelty. Overall the Go-Pay service is efficient and perspicuity, but the Go-Pay service needs to improve its novelty. This article provides additional knowledge or novelty contributions, especially for user experience analysis using FinTech applications.

description: In the context of computer assist surgical techniques, a new elastic registration method of 3D meshes is presented. In our applications, one mesh is a high density mesh (30000 vertexes), the second is a low density one (1000 vertexes). Registration is based upon the minimisation of a symmetric distance between both meshes, defined on the vertexes, in a multi resolution approach. Results on synthetic images are first presented. Then, thanks to this registration method, a statistical model of the skull is build from Computer Tomography exams collected for twelve patients.
The Mechanism of PCB Bioavailability Reduction in a Freshwater Oligochaete (Lumbriculus variegatus) after Activated Carbon Amendment

description: Hydrophobic organic compounds such as polychlorinated biphenyls (PCBs) are the most frequently occurring contaminants at EPA Superfund sediment sites. These compounds degrade very slowly and are released into sediment pore water and overlying water by diffusion and can be readily taken up by benthic organisms that form the base of aquatic food webs. The cleanup process of sediment sites is complex and creates a unique challenge due to expensive cleanup strategies, large and diverse sediment sites, presence of ecologically valuable resources, and lack of good understanding of the relation between sediment geochemistry and biouptake. In this research, PCB bioavailability to a freshwater oligochaete (Lumbriculus variegatus) was studied using four freshwater sediment samples from the Great Lakes Areas of Concern sites with a wide range of sediment geochemical characteristics (0.83 - 5.1% TOC) and PCB concentrations (0.33 to 84.7 ?g/g PCB). The work focused on understanding the impact of activated carbon (AC) amendment on PCB bioavailability. PCB aqueous equilibrium concentration and desorption rates were greatly reduced after AC amendment, indicating reductions in the two primary mechanisms of PCB bioavailability in sediments: chemical activity and chemical accessibility. AC addition at 0.5 times of sediment organic carbon reduced PCB bioaccumulation in all four study sediments. Steady state reduction in the aqueous PCB concentrations was a good predictor of PCB bioaccumulation reduction in deposit feeding organisms. A PCB mass transfer model was developed to predict the bioaccumulation of PCBs by L. variegatus. This model accounts for PCB intraparticle mass transfer, desorption from the different particle types, and uptake by benthic invertebrates through two pathways, dermal absorption and sediment ingestion. The biological and physicochemical parameters of the model were measured independently. The model was evaluated by laboratory bioaccumulation experiments for native sediments and sediments amended with activated carbon to reduce PCB bioavailability. For most PCB congeners, the modeled and measured values agreed within a factor of two for Grasse River and Milwaukee River sediments. Because the model is generic and adjustable to reflect site-specific conditions, it can be used to predict PCB bioaccumulation in a broad range of sediments and to conduct long-term risk assessments for carbon amendment to sediment.

description: We propose two novel schemes to engineer four-partite entangled Greenberger-Horne-Zeilinger (GHZ) and W states in a deterministic way by using chains of (two-level) Rydberg atoms within the framework of cavity QED. These schemes are based on the resonant interaction of the atoms with a bimodal cavity that simultaneously supports, in contrast to a single-mode cavity, two independent modes of the photon field. In addition, we suggest the schemes to reveal the non-classical correlations for the engineered GHZ and W states. It is shown how these schemes can be extended in order to produce general N-partite entangled GHZ and W states.

description: Abstract Title of Thesis: An Analysis of Discourse and Disagreement, The British & American Medical Associations Following WW II James Philip Furgol, Master of Arts, 2011 Thesis directed by: Professor Daniel Ritschel, History Department My thesis examines the contentious debates on health care reform in U.S. and British society from 1945-50. In particular, this analysis juxtaposed the positions of the U.S.'s American Medical Association (AMA) and National Medical Association (NMA) and the United Kingdom's British Medical Association (BMA) and Socialist Medical Association (SMA). From the 1940s to today specialists on health care reform have conducted numerous studies on the development of U.S. and British health care. However, this project focuses on the discourse utilized by these associations and the ideological values that largely fueled their efforts. This is a comparative study that considers issues and topics both associations addressed. These topics include the associations' proposed health care/insurance reforms as well as the actual successes/failures of such reforms. Specifically, the analyses explored each association's proposals in relation to the doctor-patient relationship, method of remuneration, and how it viewed the doctor's status within society. These analyses reveal ideological values that propelled such views. In essence, this study necessitated the comprehension of two western world powers that ultimately went in opposite directions concerning health policy. The medical associations' values reflect a part of the overall sociopolitical context of each respective country. Most importantly, this study reflects the actual degrees of conservatism, capitalism, socialism and libertarianism each association harbored by comparing its values and tactics to one another. In particular, the AMA's platform was far more conservative and capitalistic than the BMA while the SMA offered a socialistic alternative to British politicians, which was not complementary to either the AMA's or NMA's plans. The NMA promoted equal care for African American communities during a time of racial segregation. Finally, the debates amongst these groups reflect the contributions of the victors, the less successful and the outright losers in the U.S.'s and Britain's health policy development.
