description: SLHA file for a model of gluino pair production where the gluino decays via a virtual top squark to two top quarks and the lightest neutralino, with the neutralino decaying to three light quarks (uds) via the RPV coupling lambda_112. m_gluino = 2000 GeV, m_neutralino = 941 GeV
description: CERN-LHC. A search for new phenomena in final states characterized by high jet multiplicity, an isolated lepton (electron or muon) and either zero or at least three b-tagged jets is presented. The search uses 36.1 fb-1 of sqrt(s) = 13 TeV proton-proton collision data collected by the ATLAS experiment at the Large Hadron Collider in 2015 and 2016. The dominant sources of background are estimated using parameterized extrapolations, based on observables at medium jet multiplicity, to predict the b-tagged jet multiplicity distribution at the higher jet multiplicities used in the search. No significant excess over the Standard Model expectation is observed and 95% confidence-level limits are extracted constraining four simplified models of R-parity-violating supersymmetry that feature either gluino or top-squark pair production. The exclusion limits reach as high as 2.1 TeV in gluino mass and 1.2 TeV in top-squark mass in the models considered. In addition, an upper limit is set on the cross-section for Standard Model tttt production of 60 fb (6.5 times the Standard Model prediction) at 95% confidence level. Finally, model-independent limits are set on the contribution from new phenomena to the signal-region yields.

description: Background: Pesticides serve useful purposes in both commercial and domestic applications. Despite their usefulness, exposure to pesticides is associated with pesticide related illness (PRI). PRI prevention requires recognition and management of cases on an individual level and a centralized reporting system for targeted prevention on a population level. Aim: The overall aim of this study was to assess the modalities for primary and secondary prevention of PRI in Illinois and Ghana. Methods: State-based data sources in Illinois were explored for their ability to inform public health surveillance on PRI. PRI cases were estimated and characterized through probabilistic data linkage of cases across databases. Data from the Ghana Poison Control Center (GPCC) was analyzed and key informant interviews conducted to assess the potential role of the GPCC for surveillance on PRI. The training needs of healthcare providers in Ghana on PRI was assessed. Results: The Illinois Poison Center (IPC) and health facility-based data sources provided valuable information on PRI cases in Illinois but lacked essential variables necessary for prevention on a population level. Combining multiple data sources through the data linkage process yielded important characteristics about pesticide exposures and illness that were absent from single sources. There were 10, 136 pesticide exposed and PRI cases, 13 deaths, 316 “major” cases”, 1,314 “moderate” cases and 2,291 “minor” cases of PRI. There were 616 poisonings in the GPCC database out of which 15.0% were due to pesticide exposures. Ghana has less efficient data management systems and requires improved human resource capacity for public health surveillance on PRI. Existing collaborations with other state institutions require strengthening. The knowledge and experience in PRI recognition and management of healthcare providers in Ghana is varied. Few have had any specialized training on the recognition and management of PRI, and almost 90% reported that they prefer training through multiple formats. Conclusion: Public health surveillance systems for PRI can be accomplished in a cost-effective way by improving data capture in existing data sources and linking cases across these sources. Collaboration that allows the sharing of data among government agencies is an inexpensive and feasible approach for developing and sustaining PRI surveillance systems. HCPs in Ghana report a need for training on PRI recognition and management, which should enhance care of individuals as well as reporting of cases.

energy crisis

description: Following Russia's invasion of Ukraine in 2022, European countries took significant steps to reduce their reliance on energy imports from Russia, particularly in the gas and coal sectors. At the same time, to import less primary energy in the future, some countries have adopted new renewable energy targets. The question is to what extent the increase in gas and coal prices can contribute to refinancing renewable energy on the electricity wholesale market. To investigate this, an agent-based approach is used to examine the market values of renewable energies in several European countries until 2040. It is shown that increased expansion targets have a more substantial negative impact on the market values of renewable energies than increased gas and coal prices have a positive effect. In addition, it is observed that the introduction of capacity markets does not significantly influence market values and wholesale electricity prices in the medium term. However, by 2040, lower electrici

description: We analyze the two-dimensional photoelectrons momentum distribution of Ar atom ionized by midinfrared laser pulses and mainly concentrate on the energy range below 2Up. By using a generalized quantum trajectory Monte Carlo (GQTMC) simulation and comparing with the numerical solution of time-dependent Schrodinger equation (TDSE), we show that in the deep tunneling regime, the rescattered electron trajectories plays unimportant role and the interplay between the intracycle and inter-cycle results in a ring-like interference pattern. The ring-like interference pattern will mask the holographic interference structure in the low longitudinal momentum region. When the nonadiabatic tunneling contributes significantly to ionization, i.e., the Keldysh parameter 1, the contribution of the rescattered electron trajectories become large, thus holographic interference pattern can be clearly observed. Our results help paving the way for gaining physical insight into ultrafast electron dynamic process with attosecond temporal resolution.

"You Don't Know What I Went Through": Re-Making Learning in an Adult High School Equivalency Classroom
Creators: name: Gruen, Rachael
Publisher: name: University of Illinois at Chicago
Year: 2019
Subjects: Uncategorized

description: Recent policy changes to adult high school equivalency credentialing in the state of Illinois offer alternatives to passing the GED test. These alternatives include other standardized tests, transcript translation of foreign high school transcripts, and competency based diplomas (e.g. 105 ILCS 5/3-15.12). This dissertation explores the possibilities and constraints of implementing a particular competency-based curriculum in one high school equivalency classroom on the West Side of Chicago. Drawing on theories of maker pedagogies (e.g. Catterall & Peppler, 2007; Dzula, 2013; Halverson & Sheridan, 2014) and disciplinary literacies (e.g.; Buehl, 2011; Shanahan & Shanahan), this participatory action research study (Freire, 1982) uses ethnographically-informed methods with adult literacy learners as they co-design and explore learning in a maker-focused, competency-based high school equivalency curriculum. Findings indicate that the students who participated in this study implicitly and explicitly expressed a need for spaces and resources to heal from previous learning experiences. Inviting trauma narratives to be processed in the classroom through the use of maker pedagogies proved to be impactful in aiding students in the process of healing and giving them tools to feel empowered to take on more academic endeavors and career pursuits. Maker pedagogies were supportive in addressing the needs of the students because the act of composing helped students organize traumatic events as they made choices about what version they wanted to share, what they wanted to remember and forget, and what they wanted to reveal and conceal. Additionally, the collaboration that is embedded in maker pedagogies gave students an opportunity to hear feedback as a way to re-establish their sense of self post-trauma. While students used maker pedagogies to process traumas, engaging in digital tools, arts, and design thinking with the support of a caring community also allowed students to develop disciplinary literacy skills and workforce competencies.

description: In electrical impedance tomography, algorithms based on minimizing the linearized-data-fit residuum have been widely used due to their real-time implementation and satisfactory reconstructed images. However, the resulting images usually tend to contain ringing artifacts. In this work, we shall minimize the linearized-data-fit functional with respect to a linear constraint defined by the monotonicity relation in the framework of real electrode setting. Numerical results of standard phantom experiment data confirm that this new algorithm improves the quality of the reconstructed images as well as reduce the ringing artifacts.

description: Is there a relationship between visual markings of living organisms and genetic relatedness? Biologists assert that visual markings of animals are preserved through genetic inheritance. However, accurately quantifying genetic relatedness concerning visual marking similarity has not been possible until the advent of machine learning and computer vision algorithms. In this thesis, we set out to answer a question of whether genetic relatedness is correlated to visual marking similarity. We explored several machine learning and computer vision techniques to analyze the problem on bird eggs images having visual markings. We use typical image descriptors such as SIFT, LBP and CNN embeddings to learn the feature vector representation of visual patterns and explore various image similarity algorithms such as siamese neural networks, pairwise SVM and clustering techniques. We identify from the experiment's precision, recall and F-1 scores that none of the models we chose performed well and doesn't show a signal that genetic relatedness can be quantified based on visual markings similarity.

description: We extend our lattice QCD potential based study arXiv:1509.07366 (JHEP 1512 (2015) 101) of the in-medium properties of heavy quark bound states to P-wave bottomonium and charmonium. Similar to the behavior found in the S-wave channel their spectra show a characteristic broadening, as well as mass shifts to lower energy with increasing temperature. In contrast to the S-wave states, finite angular momentum leads to the survival of spectral peaks even at temperatures, where the continuum threshold reaches below the bound state remnant mass. We elaborate on the ensuing challenges in defining quarkonium dissolution, present estimates of melting temperatures for the spin averaged $χ_b$ and $χ_c$ states and contrast the findings to recent direct lattice NRQCD studies of P-wave quarkonium. As an application to heavy-ion collisions we estimate the contribution of feed down to S-wave quarkonium through the P-wave states after freezeout.

description: Previous statistical studies on the mechanical properties of chemical-vapor-deposited (CVD) suspended graphene membranes have been performed by means of measuring individual devices or with techniques that affect the material. Here, we present a colorimetry technique as a parallel, non-invasive, and affordable way of characterizing suspended graphene devices. We exploit Newton rings interference patterns to study the deformation of a double-layer graphene drum 13.2 micrometer in diameter when a pressure step is applied. By studying the time evolution of the deformation, we find that filling the drum cavity with air is 2-5 times slower than when it is purged.
Shattering the Limits of Visual Cinema: Haptic and Sensorial Visuality in Spanish Women Filmmakers

Subjects: Uncategorized

description: My dissertation, Shattering Limits of Visual Cinema: Haptic and Sensorial Visuality in Contemporary Spanish Women Directors, derives from theoretical paradigms that have lately emerged regarding film aesthetics and production, such as Laura Marks’ (2002) ‘‘haptic visuality’’, which explores and pursues the tactility and texture of images, via sound, smell or taste in film. In fact, I argue that Spanish filmmakers have turned to the haptic and sensorial aesthetics as a strategy to produce a counter-cinema that deconstructs the supremacy of voyeurism in order to provide a different type of access to material bodies on the screen, both visually and acoustically. Due to lack of recognition and visibility of women filmmakers’ work, my project seeks to give voice and visibility to the work filmmakers such as Isabel Coixet, Judith, Colell, Paula Ortiz and Helena Taberna, among others. Their films attempt to consolidate their own linguistic authority on the screen in an effort to deconstruct and reconfigure the passive/feminine- active/masculine binary options. In this project, I will examine how haptic gynofilm -to appropriate an influential term coined by Barbara Zecchi- goes beyond the limits of visual cinema to find other sources of pleasure that undermine the power relationship that interpellates male spectators as sadistic voyeurs, while simultaneously mobilizing the elements on the screen, to lead the spectator into a multisensorial journey of perception where him/ her are more inclined to ‘‘graze’’ than to ‘‘gaze’’, that is, to touch through eye, in a sort of tactile and aural voyeurism. My dissertation thus, contributes to other ways of looking and perceiving cinema, in which the feminist look and voice re-appropriated visual representation to reaffirm their own subjectivity and subvert hegemonic modes of representation and perception.

description: The motor neuron disease amyotrophic lateral sclerosis (ALS) typically begins with localized muscle weakness. Progressive, widespread paralysis often follows over a few years. Does the disease begin with local changes in a small piece of neural tissue and then spread? Or does neural decay happen independently across diverse spatial locations? The distinction matters, because local initiation may arise by local changes in a tissue microenvironment, by somatic mutation, or by various epigenetic or regulatory fluctuations in a few cells. A local trigger must be coupled with a mechanism for spread. By contrast, independent decay across spatial locations cannot begin by a local change, but must depend on some global predisposition or spatially distributed change that leads to approximately synchronous decay. This article outlines the conceptual frame by which one contrasts local triggers and spread versus parallel spatially distributed decay. Various neurodegenerative diseases differ in their mechanistic details, but all can usefully be understood as falling along a continuum of interacting local and global processes. Cancer provides an example of disease progression by local triggers and spatial spread, setting a conceptual basis for clarifying puzzles in neurodegeneration. Heart disease also has crucial interactions between global processes, such as circulating lipid levels, and local processes in the development of atherosclerotic plaques. The distinction between local and global processes helps to understand these various age-related diseases.

description: Analysis of metabolic models using constraint-based optimization has emerged as an important computational technique to elucidate and eventually predict cellular metabolism and growth. In this work, we introduce time-optimal adaptation (TOA), a new constraint-based modeling approach that allows us to evaluate the fastest possible adaptation to a pre-defined cellular state while fulfilling a given set of dynamic and static constraints. TOA falls into the mathematical problem class of time-optimal control problems, and, in its general form, can be broadly applied and thereby extends most existing constraint-based modeling frameworks. Specifically, we introduce a general mathematical framework that captures many existing constraint-based methods and define TOA within this framework. We then exemplify TOA using a coarse-grained self-replicator model and demonstrate that TOA allows us to explain several well-known experimental phenomena that are difficult to explore using existing constraint-based analysis methods. We show that TOA predicts accumulation of storage compounds in constant environments, as well as overshoot uptake metabolism after periods of nutrient scarcity. TOA shows that organisms with internal temporal degrees of freedom, such as storage, can in most environments outperform organisms with a static intracellular composition. Furthermore, TOA reveals that organisms adapted to better growth conditions than present in the environment (“optimists”) typically outperform organisms adapted to poorer growth conditions (“pessimists”).

description: We present experimental studies of the power spectrum and other fluctuation properties in the spectra of microwave networks simulating chaotic quantum graphs with violated time reversal in- variance. On the basis of our data sets we demonstrate that the power spectrum in combination with other long-range and also short-range spectral fluctuations provides a powerful tool for the identification of the symmetries and the determination of the fraction of missing levels. Such a pro- cedure is indispensable for the evaluation of the fluctuation properties in the spectra of real physical systems like, e.g., nuclei or molecules, where one has to deal with the problem of missing levels.

description: We have carried out an extensive population synthesis study of the ensemble properties of the present-day population of cataclysmic variables (PDCVs) that takes into account the nuclear evolution of high-mass donors close to the bifurcation and dynamical instability limits. Assuming the interrupted magnetic braking paradigm, we confirm many of the general features associated with the observed CV population and find enormous diversity in their secular properties. We predict that nearly half of the non-magnetic CVs with Porb > 6 hours are at least mildly evolved (i.e., greater than one-half of their MS turn-off age). Some of these systems contribute to the observed population of PDCVs in the period gap. We also see an enhancement by up to a factor of two in the probability of detecting CVs at the `minimum period'. This spike is quite narrow (approximately 5 minutes) and is attenuated because of the spectrum of WD masses and partly by the evolution of the donors. Our syntheses imply that there should be a very rapid decline in the number of ultracompact CVs (such as AM CVns). We find that between 0.05 to 1 percent of PDCVs could be UCs, and thus it is likely that the CV channel is probably not the primary contributor to the intrinsic population of UCs (especially for Porb < 30 minutes). Finally, a preliminary analysis of our results suggests that WDs in PDCVs experience a net gain in mass of less than about 0.1 Msun as a result of high mass-transfer rates early in their evolution.

description: Lebenswichtige Vorgänge entwickeln sich häufig dynamisch und in Abstimmung an die Umgebungsverhältnisse. Um den biologischen Abläufen innerhalb der Zelle geeignete Bedingungen zu gewährleisten, verfügen Zellen über zahlreiche Kompartimente mit einer strukturell und biochemisch spezifischen Zusammensetzung. Allerdings sind die überwiegend selbstständig organisierten Zellstrukturen nicht voneinander unabhängig und regulieren sich wechselseitig. Die Untersuchung von Ordnungsprinzipien in lebender Materie erfordert daher nicht nur Mikroskopiemethoden, die hochauflösende Beobachtungen ermöglichen, sondern auch Modellbildungen, um die Komplexität der erfassten Vorgänge reduzieren zu können. In der vorliegenden Arbeit werden selbstorganisierte Strukturbildungsprozesse an Lebendkulturen menschlicher Zellen untersucht. Hierzu werden fluoreszenzmarkierte Zellstrukturen mittels konfokaler Lichtmikroskopie abgebildet und deren orts- wie zeitabhängigen Rückwirkungen unter biochemischer Einflussnahmen quantifiziert. Die Ergebnisse dokumentieren eine gitterartige Anordnung der Austrittsstellen des endoplasmatischen Retikulums. Deren Eigenschaften werden entscheidend von der Beschaffenheit des endoplasmatischen Retikulums bestimmt und können mit einem diffusionsbestimmten Entmischungsprozess erklärt werden. Dabei wird eine kontrast- und auflösungsverbesserte Bildgebungsmethode konfokaler Aufnahmen charakterisiert und am tubulären Netzwerk des endoplasmatischen Retikulums angewandt. Außerdem werden die Bewegungen von Aktinfilamenten im Zellkern analysiert. Somit bildet nukleares Aktin dynamische und anpassungsfähige Strukturen, die einer heterogenen Subdiffusion in der viskoelastischen Umgebung des Zellkerns nach dem Modell einer zeitveränderlichen fraktionalen Brownschen Bewegung unterliegen. Zusammen mit den Modellerklärungen vermitteln die Ergebnisse dieser Arbeit neuartige Erkenntnisgewinne über die vielschichtigen Wechselbeziehungen zwischen der Organisation und Dynamik selbstorganisierter Vorgänge innerhalb von Zellen.
Surviving Austerity: Rape Crisis Centers and the Illinois State Budget Impasse

description: Rape crisis centers (RCCs) represent one of the most tangible advances of the modern women’s movement. Their proliferation within all 50 states is largely due to the decision by early movement activists to accept and seek out more government funding (Freinkel & Smith, 1988; Johnston, 1981). There has been little scholarly research on RCCs that takes into account both the radical history of RCCs and their current precarious position as social service providers in times of unprecedented neo-liberal reforms. This study used a mixed-methods design of analyzing existing quantitative administrative data from 34 RCCs in Illinois and 22 qualitative interviews with agency directors to better understand how a de facto austerity policy such as the Illinois budget crisis (a two year period with no state funding) affected RCCs in their ability to provide comprehensive services to survivors of sexual violence throughout the state. Quantitative results, using Interrupted Time Series (ITS) regression analysis, showed significant decreases for criminal justice advocacy, individual counseling, and telephone counseling in the overall, aggregate dataset. Rural centers showed significant decreases in medical advocacy in addition to criminal justice advocacy and large, significant increases for telephone counseling. Qualitative results revealed the ways in which agencies tried to survive the crisis through extreme cost-cutting on basic necessities such as electricity and toilet paper, reducing staff hours, and laying off a few staff members or shifting them to ‘volunteers’. These measures severely depressed staff morale, increased staff distress, and led to client perceptions of agencies as declining. The professionalization and subsequent de-politicization of RCCs over time has led to their use of ‘unobtrusive mobilization’ (Katzenstein, 1990) and empowerment frameworks (Batliwala, 2007). These orientations curtailed more confrontational or radical political activity. Instead, RCCs turned to fiscal strategies for survival such as using lines of credit, relying on reserves, and engaging in extreme agency-wide budget cuts. These strategies allowed the agencies to survive but leave many questions as to how RCCs would survive another sudden, severe loss of funding. Implications for practice and future research are discussed.

description: It is still unclear how common the Sun is when compared to other similar stars in regards to some of its physical properties, such as rotation. Considering that gyrochronology relations are widely used today to estimate ages of stars in the main sequence, and that the Sun is used to calibrate it, it is crucial to assess if these procedures are acceptable. We analyze the rotational velocities -- limited by the unknown rotation axis inclination angle -- of an unprecedented large sample of solar twins in order to study the rotational evolution of Sun-like stars, and assess if the Sun is a typical rotator. We use high-resolution ($R = 115000$) spectra obtained with the HARPS spectrograph and ESO's 3.6 m telescope at La Silla Observatory. The projected rotational velocities for 82 solar twins are estimated by line profile fitting with synthetic spectra. Macroturbulence velocities are inferred from a prescription that accurately reflects their dependence with effective temperature and luminosity of the stars. Our sample of solar twins include some spectroscopic binaries with enhanced rotational velocities, and we do not find any non-spectroscopic binaries with unusually high rotation velocities. We verified that the Sun does not have a peculiar rotation, but the solar twins exhibit rotational velocities that depart from the Skumanich relation. The Sun is a regular rotator when compared to solar twins with a similar age. Additionally, we obtain a rotational braking law that better describes the stars in our sample ($v \propto t^{-0.6}$) in contrast to previous, often-used scalings.

description: Background: Health policy formulation in general has been based upon findings from the scientific literature, expert opinion and requests from the community. It is usually the case that patients, their relatives and caregivers directly know what is missing and what they actually may want in order to take care of the patients. It will be good for policy makers to include opinions and sentiments of community patients, caregivers, and family in the formulation of policy. However, opioid policies are developed using scientific research. The assumption is that policies that take into account the opinions of the patients are more likely to develop policies that improve the health of patients based on the convergence of sentiments of patients and care givers and evidence-based research are more likely to be adopted by patients and communities Introduction: This evidence based research aims at investigating whether there is any convergence based on scientific evidence from literature and opinions of the patient population for opioid crisis H_0 1: There is no convergence between policies formulated for opioid control based on scientific publications and expert opinions and the needs of the opioid community H_1 1: There is convergence between policies formulated for opioid control and the needs of the community. To conduct this research, I use data from several journals which are scientific literatures and social media data Methods: The data above is unstructured. Therefore, i used data science, machine learning, natural language processing to analyze the data. Results: Multinomial logistic regression model with ngrams (1,3) outperformed the other approaches while analyzing journal articles. Several features were obtained from journal articles . Similarly, several features were obtained from results of social media with some sentiment words. Features with the highest score (coefficient) were selected. The needs of the community are not fully met at this time. Some of the suggestions include new policies for /to cancer patients, other disease/disorders where the pain is high, school/college going kids, border security, pharmaceutical marketing, eliminate stigma, physician training

description: We have analysed the chemical and kinematic properties of the 20 and 50 km s$^{-1}$ molecular clouds in the Central Molecular Zone of the Milky Way Galaxy, as well as those of the molecular ridge bridging these two clouds. Our work has utilized 37 molecular transitions in the 0.65, 3 and 7-mm wavebands, from the Mopra and NANTEN2 telescopes. The 0.65-mm NANTEN2 data highlights a dense condensation of emission within the western part of the 20 km s$^{-1}$ cloud, visible in only four other transitions, which are 3-mm H$^{13}$CN (1--0), H$^{13}$CO$^{+}$ (1--0), HNC (1--0) and N$_{2}$H$^{+}$ (1--0), suggesting that the condensation is moderately optically thick and cold. We find that while the relative chemical abundances between both clouds are alike in many transitions, suggesting little variation in the chemistry between both clouds; the 20 km s$^{-1}$, cold cloud is brighter than the 50 km s$^{-1}$ cloud in shock and high density tracers. The spatial distribution of enhanced emission is widespread in the 20 km s$^{-1}$ cloud, as shown via line ratio maps. The position velocity diagrams across both clouds indicate that the gas is well mixed. We show that the molecular ridge is most likely part of the 20 km s$^{-1}$ cloud and that both of them may possibly extend to include the 50 km s$^{-1}$ cloud, as part of one larger cloud. Furthermore, we expect that the 20 km s$^{-1}$ cloud is being tidally sheared as a result of the gravitational potential from Sgr A*.

description: Epilepsy is one of the leading neurological disorders characterized by recurrent seizures. These epileptic seizures are often associated with sleep stages. The longitudinal EEG studies in animal model of epilepsy have voluminous data, which is difficult to mark sleep stages manually. This demands an automated way to detect sleep and active states. We used continuous video-EEG recordings as the gold standard to characterize sleep-wake states in animals. We implemented frequency band power-based thresholding approach to detect sleep stages in 600 hours of 5 epileptic and naïve animal data. We observed that the conventional delta and theta band powers were prominently higher than the other frequency bands in the sleep-wake states however not efficient enough to detect sleep. We considered a set of novel frequency bands for their ability to robustly differentiate individual sleep states by using EEG only. We implemented k-nearest neighbor, logistic regression and brute force threshold approach. The KNN was the best predictor of sleep and wake states with 94% accuracy where the brute force was significantly similar accuracy (92%). We further characterized the sleep in epileptic animals and found that the epileptic animals sleep longer compared to naïve animals and also individual sleep durations are significantly longer than the naive animals. Such efficient algorithms can improvise and expedite sleep studies and understanding relationship between and epilepsy.

description: We analyze the time-dependent full-counting statistics of charges transmitted through a quantum dot in the coherent regime. The generating function for the time-dependent charge transfer statistics is evaluated numerically by discretizing the Keldysh time contour, which allows us to compute the higher order charge and current cumulants. We also develop an analytic expression for all order cumulants at any time given as a function of the zeros of the generating function, finding that the short time universality is due to the presence of a dominant single zero. The robustness of the universal features at short times is studied in both the sequential and coherent regimes.

description: Introduction: Low quality of care in nursing homes has been well documented and is a long-standing problem. However, few of the studies in this area have focused on the regulation of nursing homes outside of staffing regulations. This study was the first of its kind to empirically examine the relationship between state nursing home quality of care regulations and quality outcomes. Quality was measured by quality indicators used by the federal regulatory body, Center for Medicare and Medicaid Services (CMS), and consumer determined quality measured by complaints reported by state long-term care ombudsmen programs (LTCOMP). Methods: The study first compiled and analyzed state quality of care regulations and a coding scheme and longitudinal dataset of state alignment with federal standards for nine key markers was created. The law dataset was then empirically linked to outcomes, utilizing a natural experiment whereby nursing homes in some states are regulated entirely by federal standards, while nursing homes in other states are subject to federal and additional state regulations. Both pooled regression analyses and a Difference in Differences design were employed. Results: Results provided some evidence that more stringent regulation may lead to or is associated with better CMS quality outcomes, but the associations or effects were not consistent across multiple dimensions of quality. Specificity in the laws mattered. Laws with targeted and defined requirements and incorporating more clinical best practices were often associated with the intended CMS outcome, while laws which were generic in their language and without specific directions, or had relatively looser requirements, were associated with undesirable CMS outcomes. Using a difference in differences design, results showed a worsening of outcomes when a state relaxed its standards and better outcomes when a state enhanced their standards. States that went above federal standards were also often associated with increased complaints made to LTCOMPs. Conclusion: While causal inference should be limited in scope, this study can help inform policy makers at all levels and help guide important decisions about current and future regulatory initiatives. Ultimately, the results from this study have implications for over 15,000 nursing homes and 1.4 million nursing home residents.
