description: Poster presented during the 2020 annual meeting of the Medical Library Association (MLA 20 vConference and Exhibits), held July 27-August 9, 2020 ("Exploration") and August 10-14, 2020 ("Live Action Week"). The conference site also featured a recording describing poster content that was done by first author, Gabrielle Barr.

Gabrielle Barr was a 2nd year National Library of Medicine fellow at Galter Health Sciences Library & Learning Center from Sept. 2018-August 2019.
description: Background: James A. Conner and Michael L. Mason, who served in the 12th General Hospital Unit during World War II, donated their papers to the library, which were processed and digitized. The library also created an interactive digital exhibit that narrated the story of the 12th General Hospital Unit and provided the broader context through images, videos, and documents from other repositories. To draw attention to resources that promote the legacy of this prestigious medical corps, a team comprised of individuals from different departments of the library embarked upon a multi-faceted outreach mission.Description: Over the course of three months, we publicized the exhibit through social media and digital signage, and invited a military medicine expert to speak at the inauguration event for the exhibit. We performed genealogical research to find relatives of those who served and invited them to attend and participate in the inaugural event. Members of the team called the descendants that could be located and wrote them personalized notes on stationery with photographs from the collection and a link to the digital exhibit. The team also created a five-panel traveling banner display to be unveiled at the lunchtime speaker event. Following the speaker event, the library had an open house for visitors to see the 12th General Hospital materials. The event was covered by the campus media as well as by the Chicago Tribune and NPR.Conclusion: With more than 150 attendees from across the country at the speaker event, the display of the traveling banner exhibit at locations in the Chicago area, and the increase of remote and in-person reference requests about the 12th General Hospital, the outreach activities the library developed during the summer of 2019 proved to be successful. The library has since used some of these tactics like the traveling banner exhibit to highlight other special collections projects and has most importantly learned several lessons on how to manage a large-scale outreach campaign.

description: Traffic signal controllers play an essential role in today's traffic system. However, the majority of them currently is not sufficiently flexible or adaptive to generate optimal traffic schedules. In this paper we present an approach to learning policies for signal controllers using deep reinforcement learning aiming for optimized traffic flow. Our method uses a novel formulation of the reward function that simultaneously considers efficiency and equity. We furthermore present a general approach to find the bound for the proposed equity factor and we introduce the adaptive discounting approach that greatly stabilizes learning and helps to maintain a high flexibility of green light duration. The experimental evaluations on both simulated and real-world data demonstrate that our proposed algorithm achieves state-of-the-art performance (previously held by traditional non-learning methods) on a wide range of traffic situations.

THE DISEQUILIBRIUM EFFECTS OF TECHNOLOGICAL CHANGE ON PRICES AND THE RATE OF PROFIT (MARX, VALUE, SIMULATION, TRANSFORMATION)
Creators: name: White, Richard H.
Publisher: name: American University
Year: 2023

description: Marx's writings do not support the common characterization of his political economy as a model of economic equilibrium under capitalism. This is clear when it is demonstrated that his theories of the transformation of value into price (transformation) and the tendency of the rate of profit to fall (TRPF) may be reconciled with his basic writings on value theory, if the notion of a disequilibrium analysis is entertained. In this paper such a disequilibrium framework is developed, and computer simulation is used to test relevant hypotheses. First, the methodological consistency of Marx's transformation with his analysis of the forms of value is established. This leads to the rejection of the position that input value and output price must be equated for there to be a solution to the transformation "problem." Removal of the common conception of equilibrium also affords a clearer picture of how Marx views the regulation of price by underlying value relations. Second, it is demonstrated that a link between TRPF and transformation exists. TRPF is shown to be the application of Marx's transformation methodology to value analysis under the assumption of continuous technological change. Numeric simulations which depict such processes then demonstrate the possibility of temporary and permanent declines in the average rate of profit. It is important that these declines are shown to occur under the very conditions of technological change suggested by Marx. Finally, it is concluded that transformation and TRPF are part of a larger, unified conception of economic processes held by Marx. As such they must be viewed as a unity within a disequilibrium framework of analysis if Marx's methodology is to be retained.

Here $G$ is a connected Lie group with Lie-algebra $\g$. For a transitive $\g$-action the completion is of the form $G/H$ for a Lie subgroup $H$ which need not be closed. In general the completion can be constructed by completing each $\g$-orbit.

description: The coronavirus disease 2019 (COVID-19) emerged as a pandemic in late March 2020, with cases escalating in the US. Health disparities, caused by underlying low socioeconomic factors, are heightened in the current COVID-19 pandemic and response. These health disparities are especially evident for disenfranchised populations like low-income, Black and Hispanic, and incarcerated communities. This scoping review was conducted to provide an overview of the evidence that highlights the need for public health policies sensitive to socioeconomic and health disparities in the US. First, the review provides evidence suggesting that low-income earners, Blacks and Hispanics, and incarcerated populations are among those with the greatest risk for COVID-19 due to underlying disparities. Second, it contains a review of the research that suggests these populations also have a decreased ability to adhere to social-distancing directives. The results suggest that there is an increased burden and exposure to COVID-19 among the poor, Blacks and Hispanics and incarcerated, and that these populations are less able to follow social-distancing guidelines. Overall, new policies should challenge existing socioeconomic and health disparities by addressing economic security, housing security, criminal justice, and healthcare access. Therefore, the current COVID-19 pandemic response needs to be part of a larger effort to combat health and socioeconomic inequity in the US.

description: This paper offers a new approach to the estimation of marginal net perceived benefits from public goods, It is designed to utilize information from survey data which consist of answers to the question: Should more, less or the same amount of tax money be spent on program X? Widespread availability of such data, and their relative underutilization, motivated this research,. Considerable disparities are found in perceived benefits over various age groups, educational attainments and geographical locations, emphasizing that deciding which public goods to supply and how much of them has important distributive, as well as allocative, implications.

description: We investigate the dynamics of Brownian particles in internal state- dependent symmetric and periodic potentials. Although no space or time symmetry of the Hamiltonian is broken, we show that directed transport can appear. We demonstrate that the directed motion is induced by breaking the symmetry of the transition rates between the potentials when these are spatially shifted. Finally, we discuss the possibility of realizing our model in a system of cold particles trapped in optical lattices.

description: We present molecular dynamics simulations of solid NaNO$_2$ using pair potentials with the rigid-ion model. The crystal potential surface is calculated by using an \emph{a priori} method which integrates the \emph{ab initio} calculations with the Gordon-Kim electron gas theory. This approach is carefully examined by using different population analysis methods and comparing the intermolecular interactions resulting from this approach with those from the \emph{ab initio} Hartree-Fock calculations. Our numerics shows that the ferroelectric-paraelectric phase transition in solid NaNO$_2$ is triggered by rotation of the nitrite ions around the crystallographical c axis, in agreement with recent X-ray experiments [Gohda \textit{et al.}, Phys. Rev. B \textbf{63}, 14101 (2000)]. The crystal-field effects on the nitrite ion are also addressed. Remarkable internal charge-transfer effect is found.

description: The following dissertation is an analysis of the historical and structural formation and development of Iranian labor organizations during the years 1926 - 1978. It analyses Iranian labor history in the context of capitalist transformations in modern Iran. It studies the development of various forms of labor organizations (e.g., guild systems, craft trade unions, and industrial trade unions), and their relevance to the actual organization of the labor process in pre-capitalist as well as in capitalist production relations in contemporary Iran. Different modes of the organization of labor processes (traditional and modern) coexist and develop simultaneously, a fact which has direct implications for the problem of "underdevelopment" in Iran. This study, through a comparative analysis of the historical periods of the politics of Iranian labor organizations, reveals that there has been a lack of correspondence between the structural economic development of the work process and the development of political labor organizations in twentieth century Iran. It shows how social and political factors (e.g., the urban origins of workers and the contact of Iranian migrant workers with the Russian labor movement) more than economic ones, have played a greater role in determining the development of workers' organizations and their politics. This also reveals the historical experiences of the labor movement as an important element of the politics of the labor process. In this regard it argues that a premature discontinuity in the historical experience of the workers' movement in Iran after the 1953 coup contributed to the process of disorganization and the submission of the working class to the populist ideology of the urban poor in later years. Iranian "underdevelopment" is structured in terms of the coexistence of different forms of labor processes that reinforce each other. Traditional petty commodity production is not only surviving but also growing alongside more developed capitalist production. In other words, contemporary Iran has experienced a simultaneous process of development and growth of both modern social and economic relations (e.g., industrialization, urbanization, secularization) and traditional structures and relations (e.g., petty commodity production, religious ideas and institutions).
Electron-positron annihilation into two photons in an intense plane-wave field

description: The process of electron-positron annihilation into two photons in the presence of an intense classical plane wave of an arbitrary shape is investigated analytically by employing light-cone quantization and by taking into account the effects of the plane wave exactly. We introduce a general description of second-order 2-to-2 scattering processes in a plane-wave background field, indicating the necessity of considering the localization of the colliding particles and achieving that by means of wave packets. We define a local cross section in the background field, which generalizes the vacuum cross section and which, though not being directly an observable, allows for a comparison between the results in the plane wave and in vacuum without relying on the shape of the incoming wave packets. Two possible cascade or two-step channels have been identified in the annihilation process and an alternative way of representing the two-step and one-step contributions via a "virtuality" integral has been found. Finally, we compute the total local cross section to leading order in the coupling between the electron-positron field and the quantized photon field, excluding the interference between the two leading-order diagrams arising from the exchange of the two final photons, and express it in a relatively compact form. In contrast to processes in a background field initiated by a single particle, the pair annihilation into two photons, in fact, also occurs in vacuum. Our result naturally embeds the vacuum part and reduces to the vacuum expression, known in the literature, in the case of a vanishing laser field.

description: In this work, functionally graded materials Ti/HAP were fabricated at n=0.8, 1 and 1.2 and characterized of by XRD and SEM to evaluate the formed layers in FGMs. Some physical properties were measured for fabricated FGMs include particle size analysis, apparent density, green density, green porosity and shrinkage. The results showed that there are many compounds may be formed between Ti and HAP after sintering at 1000oC for 2 hrs. The XRD analysis indicated the presence of TICP, CaO, Ti4P3 and TiO2. The SEM images confirm the formation of the later compounds. Because of important of advanced materials such as FGMs as alternative industrial material, it’s necessary to measure the properties of these materials. Apparent density was measured for fabricated FGMs and the results indicated that the converting from 1st to 5th layer led to decreasing of apparent density, while the increasing of n value led to increasing apparent density due to increasing of Ti percentage in the layer. Green density and porosity are important factors for materials. The results showed the green density increased with increasing in (n) value, green porosity was decreased with increasing of (n) valuebecause of decreasing in HAP percentage in layer.

description: Federal tax policy has the potential to affect the economic behavior and well-being of farm households, as well as the management and profitability of farms. Because the overwhelming majority of U.S. farms are organized as passthrough entities—sole proprietorships, partnerships, and S corporations—farm households are affected by individual income tax rates and preferences, in addition to deductions, credits, deferrals, and other tax provisions that pertain to businesses. The recently passed Tax Cuts and Jobs Act (TCJA) of 2017 made significant changes to the Federal income tax system. The TCJA eliminates or modifies many itemized deductions and tax credits, while lowering tax rates on individual and business income. At the same time, the TCJA expands some business provisions, in particular those that relate to capital cost recovery. It also doubles the estate tax exclusion by raising the amount to almost $11.2 million for an individual. This report uses published and special tabulation data obtained from the Internal Revenue Service and farm-level data from USDA’s Agricultural Resource Management Survey to analyze the impact the TCJA could have on family farms. We estimate that as a result of the changes made by the TCJA, family farm households would have faced an estimated average effective income tax rate of 13.9 percent if the TCJA had been in place in 2016. Under the previous tax law, family farm households faced an estimated average effective income tax rate of 17.2 percent. Although average tax rates are estimated to decline across all farm sizes and commodity specializations, the effects of the TCJA on farm households vary by farm size. Estimates also suggest 0.1 percent of farm estates will be subject to the estate tax under the new law, down from the 0.86 percent under previous law.

description: Demand for ready-to-eat foods from restaurants and grocery stores has been growing in the United States. These foods save households time in meal preparation, but they have also been associated with inferior dietary quality and, consequently, poor health for Americans. The demand for such “convenience foods” varies significantly from person to person, and the factors that influence these individual choices are not clear. This study considers four broad groups of factors: consumers’ financial resources, prices, consumers’ time constraints, and the food environment consumers face. We find that higher income is associated with increased demand for restaurant food, while participation in food assistance programs is associated with increased demand for ready-to-eat and non-ready-to-eat supermarket food. Consumers facing tight time constraints from employment tend to purchase more food from full-service restaurants and less from supermarkets. On the other hand, consumers whose time constraints stem from childcare responsibilities tend to purchase more fast food. The location of restaurants and stores has little effect on demand for convenience foods after controlling for financial resources, time constraints, and relative prices.

description: Friction stir processing (FSP) is a promising technique to improve the mechanical properties of the polymer blends surface with retainment of bulk properties, in this work an attempt was done to add different ratios of polypropylene (PP), styrene acrylonitrile (SAN) and polyvinyl chloride (PVC) as a second material to the matrix plate high density polyethylene (HDPE). Mechanical properties were estimated for hardness and tensile tests were carried out to assess the performance of friction stir processed to prepared the binary polymers blends (HDPE: PP), (HDPE: SAN) and (HDPE: PVC) at depth 3 mm from the surface of (HDPE) plate. The results of the tests showed that the best values of the tensile strength, young modulus and hardness, it was obtained when adding the ratio of (15%) of the (PVC) to matrix (HDPE). The friction stir processing technique was successfully used to improve the mechanical properties of polymer surface. In view of the foregoing, it can be concluded that the friction stir processing technique, can be utilizing to repair the cracks and imperfections that are formed in polymeric materials.

description: With the shale revolution, annual oil and gas production in the United States grew by 69 percent from 2005 to 2014, and almost 67 percent of the production occurred on farmland in 2014. The effect of oil and gas development on farm sector finances is not well understood. Limited nationwide information exists on issues such as the extent that farm operators and landlords own the rights to the oil and gas beneath their land, the value of the rights, or the timing and prevalence of leasing with energy firms. Subsurface ownership affects the ability of operators and landlords to benefit financially from development and to shape the terms on which it occurs. Using data from USDA’s Tenure, Ownership, and Transition of Agricultural Land (TOTAL) survey, Drillinginfo, and USDA’s 2012 Census of Agriculture, this report quantifies the farm sector’s oil and gas wealth and income, and provides a basis for understanding how booms and busts in oil and gas production and prices might affect farm-sector finances.

description: This report describes the current landscape of Federal risk management policies, including the Agricultural Act of 2014, and analyzes the outcomes and interactions of these programs. Despite their common objective of risk reduction, Federal programs differ in their payment mechanisms and their impacts on producer revenue, and uptake has varied significantly across programs and crops. Area-loss insurance programs, such as the Stacked Income Protection Plan and Supplemental Coverage Option, received low enrollments, while applications to the Noninsured Crop Disaster Assistance Program witnessed sizable growth. Differences in program enrollment and program provisions across crops led the bulk of Agriculture Risk Coverage payments to go to producers with corn and soybean base acres, while most Price Loss Coverage payments went to rice, peanuts, and wheat base acres. Half of dairy producers enrolled in the Margin Protection Program for Dairy, but large national margins led to few payments in 2015 and 2016. In contrast, changes in program design led the Livestock Gross Margin for Dairy program to make significantly more indemnity payments per policy. Outside of dairy, the Livestock Forage Program remains the largest livestock support program, though outlays have fallen in recent years.

description: Transition metal dichalcogenide (TMD) bilayers are a new class of tunable moiré systems attracting interest as quantum simulators of strongly-interacting electrons in two dimensions. In particular, recent theory predicts that the correlated insulator observed in WSe$_2$/WS$_2$ at half filling is a charge-transfer insulator similar to cuprates and, upon further hole doping, exhibits a transfer of charge from anion-like to cation-like orbitals at different locations in the moiré unit cell. In this work, we demonstrate that in this doped charge-transfer insulator, tightly-bound charge-2e excitations can form to lower the total electrostatic repulsion. This composite excitation, which we dub a trimer, consists of a pair of holes bound to a charge-transfer exciton. When the bandwidth of doped holes is small, trimers crystallize into insulating pair density waves at a sequence of commensurate doping levels. When the bandwidth becomes comparable to the pair binding energy, itinerant holes and charge-2e trimers interact resonantly, leading to unconventional superconductivity similar to superfluidity in an ultracold Fermi gas near Feshbach resonance. Our theory is broadly applicable to strongly-interacting charge-transfer insulators, such as WSe$_2$/WS$_2$ or TMD homobilayers under an applied electric field.

HISTORICAL AND STRUCTURAL DEVELOPMENT OF THE POLITICS OF PRODUCTION IN MODERN IRAN, 1926-1978

description: The following dissertation is an analysis of the historical and structural formation and development of Iranian labor organizations during the years 1926 - 1978. It analyses Iranian labor history in the context of capitalist transformations in modern Iran. It studies the development of various forms of labor organizations (e.g., guild systems, craft trade unions, and industrial trade unions), and their relevance to the actual organization of the labor process in pre-capitalist as well as in capitalist production relations in contemporary Iran. Different modes of the organization of labor processes (traditional and modern) coexist and develop simultaneously, a fact which has direct implications for the problem of "underdevelopment" in Iran. This study, through a comparative analysis of the historical periods of the politics of Iranian labor organizations, reveals that there has been a lack of correspondence between the structural economic development of the work process and the development of political labor organizations in twentieth century Iran. It shows how social and political factors (e.g., the urban origins of workers and the contact of Iranian migrant workers with the Russian labor movement) more than economic ones, have played a greater role in determining the development of workers' organizations and their politics. This also reveals the historical experiences of the labor movement as an important element of the politics of the labor process. In this regard it argues that a premature discontinuity in the historical experience of the workers' movement in Iran after the 1953 coup contributed to the process of disorganization and the submission of the working class to the populist ideology of the urban poor in later years. Iranian "underdevelopment" is structured in terms of the coexistence of different forms of labor processes that reinforce each other. Traditional petty commodity production is not only surviving but also growing alongside more developed capitalist production. In other words, contemporary Iran has experienced a simultaneous process of development and growth of both modern social and economic relations (e.g., industrialization, urbanization, secularization) and traditional structures and relations (e.g., petty commodity production, religious ideas and institutions).
THE IMPACT OF THE GERMAN OCCUPATION OF FRANCE UPON FOUR FRENCH INTELLECTUALS: CHARLES MAURRAS, PIERRE DRIEU LA ROCHELLE, HENRY DE MONTHERLANT, AND FRANCOIS MAURIAC

description: The dissertation examines the influence of the German occupation of France (1940-1944) on four prominent French writers. Its objective is to emphasize their reactions, their attitudes, their stances, and their roles during these four fateful years of French history. An introductory first chapter deals with the dilemma of the French intellectuals in general and with the choices open to them at the very beginning of the Occupation, when German and French censorship imposed restrictions on all publications in the occupied and unoccupied zones. The four main chapters of the dissertation are devoted to the lives of Charles Maurras, Pierre Drieu la Rochelle, Henry de Montherlant, and Francois Mauriac. These intellectuals have been selected because their respective attitudes before and during the Occupation reflected the spectrum of the French Rightists' political division. Each chapter contains an analysis of the authors' political convictions between the two world wars and a summary of the solutions they each proposed to heal France's political and social problems. But the essential theme of the dissertation is to highlight the frustrations and the plight of these writers who dared to commit themselves in unusual and dangerous circumstances. The conclusion is an attempt to evaluate the consequences of their commitment in the realms or moral responsibilities and justice. Although the bibliographies of these authors are very extensive, their works have not yet been studied in this context. Some of the articles and political essays which they wrote have never been translated into English. The statements they made have often been cited out of context and misinterpreted in the heat of the revengeful years of the purge which followed the occupation of France. The dissertation attempts to separate truth from fiction and reality from slander. The methodology consists in the textual and bibliographical study of the authors' original works in the French language.

description: The economic sustainability of farm households is frequently dependent on the availability of off- farm employment. This paper uses farm-level data to examine the impact of the Common Agricultural Policy (CAP) direct payment scheme, farm household characteristics and agricultural market conditions on farm households’ labour allocation decisions in Ireland. Among other things, the hypothesis that decoupled direct payments induce farm household members to allocate more time to off-farm employment is tested. The analysis presented here suggests that decoupled direct payments are significantly and negatively associated with both the probability and amount of time allocated to off-farm work in the case of the farm operator. For married couples, the analysis finds a negative relationship between decoupled payments and the probability of both the farm operator and the spouse working in off-farm employment. Interestingly, decoupled payments have no significant relationship with the probability of the spouse only working in off-farm employment. This result corresponds to the finding of (El-Osta et al. 2008) and suggests that decoupled payments tend to play a very limited role in explaining the off-farm employment decisions of the spouse. At a time of increased volatility in farm incomes and uncertainty in agricultural policy, this analysis contributes to our understanding about the importance of off-farm labour in supporting farm household income. Furthermore, the analysis contributes to our understanding about the role of the farm spouse in contributing towards farm household income, the farm viability and the relationship between off-farm labour decisions and agricultural policy.

description: We present a quantum phase space model of Bose-Einstein condensate (BEC) in a double well potential. In a two-mode Fock-state analysis we examine the eigenvectors and eigenvalues and find that the energy correlation diagram indicates a transition from a delocalized to a fragmented regime. Phase space information is extracted from the stationary quantum states using the Husimi distribution function. It is shown that the quantum states are localized on the known classical phase space orbits of a nonrigid physical pendulum, and thus the novel phase space characteristics of a nonrigid physical pendulum such as the $π$ motions are seen to be a property of the exact quantum states. Low lying states are harmonic oscillator like libration states while the higher lying states are Schrödinger cat-like superpositions of two pendulum rotor states. To study the dynamics in phase space, a comparison is made between a displaced quantum wavepacket and the trajectories of a swarm of points in classical phase space. For a driven double well, it is shown that the classical chaotic dynamics is manifest in the dynamics of the quantum states pictured using the Husimi distribution. Phase space analogy also suggests that a $π$ phase displaced wavepacket put on the unstable fixed point on a separatrix will bifurcate to create a superposition of two pendulum rotor states - a Schrödinger cat state (number entangled state) for BEC. It is shown that the choice of initial barrier height and ramping, following a $π$ phase imprinting on the condensate, can be used to generate controlled entangled number states with tunable extremity and sharpness.
