  • 1. Al Rikabi, Fouad Experimental and Numerical Study on Synthetic Fiber-Reinforced Concrete Pipes

    Doctor of Philosophy (PhD), Ohio University, 2020, Civil Engineering (Engineering and Technology)

    Synthetic fibers have been recently used in a concrete mixture in an attempt to produce a new concrete pipe system, cheaper, lighter, and more flexible than conventional steel reinforced concrete pipes. However, no structural design codes have been introduced for synthetic fiber reinforced concrete pipes evaluation. Also, there is little in the literature regarding synthetic fiber applications in the concrete pipes. The effect of adding two types of synthetic fiber, polypropylene (PP) and polyvinyl alcohol (PVA) fibers, on the mechanical properties of concrete, including CTE, dynamic modulus of elasticity, and flexural strength, was investigated. Also, this study focused on the evaluation of the synthetic fiber reinforced concrete pipes performance in terms of ASTM requirements for strength, stiffness, and ductility, and developing design tables for synthetic fiber reinforced concrete pipe similar to those proposed in ASTM C76 standard using the numerical analysis. The performance of the synthetic fiber reinforced concrete pipes were evaluated under short- and long-term loading in accordance with ASTM protocols using different pipe diameters. Fiber dosages ranged from 4.75 to 18 kg/m3 (8 to 30 lb/yd3), and different areas of one steel cage layer were used to reinforce the concrete pipes. The finite element model of the three-edge bearing test was calibrated and validated using the experimental results. The linear and non-linear behavior of the synthetic fiber reinforced concrete material was characterized using the concrete damage plasticity (CDP) model. For input data representing the concrete material properties compression strength, tensile strength, and modulus of elasticity were determined for five fiber dosages 0, 4.75, 6, 7, and 9 kg/m3 (0, 8, 10, 12, and 15 lb/yd3). The results showed that adding fiber to concrete enhanced the flexural strength, increased flexibility, decreased the dynamic modulus of elasticity, and increased the CTE.

  • 2. Fredriksen, Lauren The Impact of Memory Stereotype Threat on Memory and Memory Self-Efficacy in Older Adults

    Doctor of Psychology (Psy.D.), Xavier University, 2020, Psychology

    This study examined the impact of memory stereotype threat on memory duration (e.g., short-term and long-term) and modality (e.g., verbal and non-verbal), and memory self-efficacy in older adults who live independently (Mage = 77 years). Participants (N = 66) were randomly assigned to a group that received either neutral instructions (n = 32) or memory stereotype threat inducing instructions (n = 34). Participants completed the California Verbal Memory Test-Second Edition (CVLT-2), the Rey Complex Figure Test (RCFT), a memory self-efficacy measure, and a demographics survey. The main effect of the within-subjects factor of a 2 x 2 mixed analysis of variance (ANOVA) indicated that participants performed significantly better on short-term non-verbal memory than long-term non-verbal memory. There was no significant difference between the neutral and stereotype threat groups in memory modality or duration. However, an independent samples t-test indicated that participants in the memory stereotype threat group reported significantly lower memory self-efficacy than participants in the neutral group. These results may indicate that the instructions used to induce memory stereotype threat may not have been phrased strongly enough to elicit poorer performance on the CVLT-2 and RCFT in the memory stereotype threat group. Additionally, participants reported having a high level of education (i.e., a master's degree was the modal educational level), which may limit generalizability of the results. The findings call for future research to explore the impact of level of education on memory self-efficacy in older adults. Also, future research may focus on the impact of the strength of memory stereotype threat manipulation on memory performance.

  • 3. Svitlova, Olena Six-Nine Months Long Term Culture of Mouse Bone Marrow Cells Differentiated to Macrophages and Eosinophils

    Master of Science (MS), Wright State University, 2019, Microbiology and Immunology

    Mouse models of eosinophil-associated diseases have been used to study the mechanisms of disease pathogenesis. In this study, mouse-derived bone marrow cells were used in long-term (6 and 9 months) cell cultures of differentiated eosinophils and macrophages. IL-5 was used to differentiate the stem cells to eosinophils and GM-CSF was used to propagate macrophages from the bone marrow stem cells. The maximum time period for observing the eosinophil cultures was 252 days which is censurably longer than the 18 days culture period observed by others. The results were assessed by describing the microscopic cell morphology by Wright staining, modified Giemsa staining and protein expression by immunofluorescent staining. The GMCSF-stimulated bone marrow cultures produced classically appearing monocyte/macrophages throughout the study and were used to compare the development of the eosinophils over the long-term period of observation. Differentiation of the BM cells was carried out using with growth factors (SCF, FLT3L) and cytokines (IL-5, GM-CSF) over the 252 days period. The most suitable culture plate for long-term of cell growth were thee 60 mm petri dishes. At 252 days, the eosinophils exhibited as bi-lobed nuclear shapes, comparable with human eosinophils. Dendrite-like ramifications were observed on the surfaces of these eosinophils. Long term culture of eosinophils in the presence of IL-5 contributed to formation of eosinophil extracellular traps (EETs) areas. Within the EETs the cells surface of eosinophils developed holes; the nucleus of such cells lost the “ring-like” or “lobular” morphology and appeared in de-condensed fashion. Within the EETs, the plasma membranes of eosinophils developed the protrusions containing cytoplasmic granules. The EETs and protrusions had not been observed previously in the mouse eosinophil models in vitro but were described in human eosinophils. Consequently, the long-term culture of mouse bone-marrow derived eosinophil (open full item for complete abstract)

  • 4. Gonzalez-Maldonado, Noelymar Evaluating the Effects of Long-Term No-Till and Crop Rotations in Soil Health and Corn Productivity

    Master of Science, The Ohio State University, 2019, Environment and Natural Resources

    Conservation practices, such as no-till and diversifying crop rotations are known for their capacity to reduce soil erosion and improve soil properties. However, the impact of these management practices on emerging soil health tests and the ability of these tests to reflect active organic matter dynamics and nutrient cycling, and corn productivity has not been explored. This project focused on determining the effects of half a century of continuous tillage treatments (moldboard plow, chisel till, and no-till) and crop rotations (continuous corn, corn-soybean, and corn-forage-forage) on soil health indicators and its relationship with crop productivity. The forages were alfalfa in Wooster and red clover and oats in Northwest. Soil labile carbon (C) and nitrogen (N) temporal dynamics were quantified with permanganate oxidizable C (POXC), mineralizable carbon (Min C), and soil protein at six key stages in corn (Zea mays) development: before planting (around three weeks before planting), V5, V10, R1, R4, R6 in the 2017 and 2018 growing seasons. Corn leaf chlorophyll, aboveground plant biomass, nutrient uptake, and grain yield were also quantified. The soil health indicators (POXC, Min C, soil protein) and crop parameters (leaf chlorophyll, total nitrogen uptake, and total aboveground biomass) were higher in reduced tillage (chisel and no-till) compared to moldboard plow and higher in the most diverse crop rotation (corn-forage-forage) compared to corn-soybean. Corn yields were not significantly different between tillage treatments but were higher in the more diverse rotations (corn-soybean and corn-forage-forage) compared to corn monoculture. Although the treatment effects varied by site and year, rotation had a consistently larger effect on soil health indicators and corn productivity than tillage, highlighting the importance of including crop rotations in corn production. We conclude that Ohio soils under half a century of continuous tillage and rotation treatments ha (open full item for complete abstract)

  • 5. Chaulagain, Dewan Hybrid Analysis of Android Applications for Security Vetting

    Master of Science (MS), Bowling Green State University, 2019, Computer Science

    The phenomenal growth in use of android devices in the recent years has also been accompanied by the rise of android malware. This reality created the need to develop tools and techniques to analyze android apps in large scale for security vetting. Most of the state-of-the-art vetting tools are either based on static analysis (analysis without executing apps) or on dynamic analysis (running them on an emulation platform). Static analysis suffers from high rate of false positives, and it has limited success if the app developer utilizes sophisticated evading features. Dynamic analysis on the other hand overcomes the problems associated with static analysis but may not find all the code execution paths, which prevents us from detecting some malware. Moreover, the existing static and dynamic analysis vetting techniques require extensive human interaction. To address the above issues, we design a deep learning based hybrid analysis technique, which com- bines the complementary strengths of each analysis paradigm to attain better accuracy. Moreover, automated feature engineering capability of the deep learning framework addresses the human in- teraction problem. In particular, using standard static and dynamic analysis procedure, we obtain multiple artifacts and train the deep learner with the artifacts to create independent models and then combine their results using a hybrid classifier to obtain the final vetting decision (malicious apps vs. benign apps). The experiments show that our best deep learning model with hybrid anal- ysis achieves an area under the precision-recall curve (AUC) of 0.9998. Furthermore, the time to test an app is significantly less compared to traditional static analysis tools. In this thesis, we also do a comparative study of the accuracy and performance measures of the various variants of the deep learning framework.

    Psy. D., Antioch University, 2018, Antioch New England: Clinical Psychology

    A retrospective research study evaluated archival data on client engagement from a program evaluation project implemented at the Psychological Services Center at Antioch University New England. Student researchers from the Center for Behavioral Health Innovation (formerly Center for Research of Psychological Practices) partnered with the Antioch University Psychological Services Center (PSC) to investigate the impact of client early engagement on drop-out rates and therapy outcomes of mental health clients. Potential participants were administered a brief questionnaire, prior to the first session via phone call, to assess their readiness, expectations of therapy, potential barriers to seeking treatment, and their initial impression of the clinic. Evaluating the effects of client readiness on the working alliance and early treatment outcomes of 28 participants did not yield a significant effect. However, a nested path analysis revealed a significant effect for clinic timeliness as a moderator between two groups. In other words, predictive effects were observed between client readiness variables and the working alliance.

  • 7. Astafev, Artem Age and Sex-Specific Effect of Caloric Restriction on Circadian Clock and Longevity-Associated Gene Expression

    Master of Science in Biology, Cleveland State University, 2017, College of Sciences and Health Professions

    The rhythms in the expression of circadian clock genes are affected by calorie restriction (CR), a dietary paradigm known to increase lifespan. In our current study, we show that circadian rhythms are influenced by sex and the effects of CR are different between males and females. In particular, we found a group of clock genes which showed a sex-dependent difference in expression, as well as in response to CR (Rev-Erb α, Ror γ and both Cryptochromes: Cry1 and Cry2 genes). Two clock genes showed no difference in expression but their response to CR showed sexual dimorphism (Ror α and Rev-Erb β). Finally, we found some of the clock genes to be expressed in a sex-independent manner (Bmal1, Per1, Per2 and Per3). The response to CR for these genes did not show sexual dimorphism as well. Several genes were also previously reported to be regulated by CR. These genes showed a sex-dependent difference in expression as well as the sexual dimorphism in the response to CR in mouse liver (Fmo3, Mup4, Serpina12, Cyp4a12b and Cyp4a14a). IGF signaling plays an important role in aging and CR effects. Igf-1 expression is regulated by CR and by the circadian clock, we found that rhythms in Igf-1 expression have sexual dimorphism.We also investigated the differences in expression levels in young versus old mice to see if the effect of short-term CR differs from the effect of long-term CR. In all of the 4 analyzed genes, the expression does not change with age. The effect of CR on the expression of 2 out of 4 genes (Bmal1 and Per2) was lost upon long-term exposure to CR. For the other 2 genes (Per1 and Per3) the effect of CR persisted over time. Thus we emphasize that sex and age are important factors for consideration when administering CR.

  • 8. Dai, Honghao Optimization of Financial Decision for Elder Care Services Using Markov Chain Modeling

    MS, University of Cincinnati, 2017, Engineering and Applied Science: Mechanical Engineering

    This thesis presents a unified approach to integrate progressive care processes, multiple financial resources with the objective of satisfying elder's demand for services. Under the proposed elder care framework, several modeling tasks, prediction of elder's remaining life time, classification of elder's preference for care services, estimation of elder's care costs, and optimization of financial decisions are addressed systematically. An elder care financial plan is provided to maximize the elder's care service level with optimal purchasing decisions on financial resources. Markov Chain model is developed for predicting remaining life time. Personal physical profile is introduced in the form of covariates which are age, gender, health indicator and health history. It influences the transition probabilities from a care stage to another, so elders have their unique transition probability matrix in Markov model. Service level and pricing model aims to quantify elder's preference of care services through classification. Three financial resources are modeled: Medicare, long-term care insurance and reverse mortgage. The optimization model selects service fill rate as objective to maximize the depth of demand that is satisfied by the benefits from financial resources. The balance of total care costs, benefits and premiums of financial resources serve as main constraint. Furthermore, a heuristic algorithm is developed to enable these models work together to search for optimal solution. A case study is designed to show optimal decision sets. Purchasing decision set includes daily benefits, benefit period and purchasing age for long-term care insurance, purchasing age and contract rate for reverse mortgage. With the input of personal health profile, an optimal financial plan can be generated and track the wealth status (care cost, savings, benefits, and premium) of elder. Then, sensitivity analysis is carried out to investigate the uncertainty from personal health indica (open full item for complete abstract)

  • 9. Añorga, Angel Students' Self-Efficacy Perceptions of Second Language Learning: Experiences in a Short-term Study Abroad

    EdD, University of Cincinnati, 2016, Education, Criminal Justice, and Human Services: Literacy and Second Language Studies

    Short-term language study abroad programs have continued to capture the attention of college students in recent years. In an effort to measure the impact, language gain from a short-term study abroad program is measured using pre- and post-grammar-based assessments alone. Such practice takes away the essence and richness short sojourns can offer, especially as this type of assessment does not always account for those students considered to be bad test-takers. The process of language learning is, by nature, a complex task. When studying abroad, this process encompasses three main domains: the language learner, the second language, and the immersion setting. The intrinsic permeability among these domains reveals the complexity of the process of language learning abroad, particularly when the sojourn is short term. Every language learner who studies abroad is unique and experiences the language learning process at a different level. Thus, from a self-efficacy theory perspective—and to allow the voices and stories of the participants to be heard—this study implements a phenomenological case study design to gain insights into participants' self-efficacy perceptions of their language learning abroad. Self-efficacy is identified in the literature as the central phenomenon influencing students' achievement as well as the determining factor of students' success during a short-term sojourn. In this study, five cases shared their stories regarding the process of learning Spanish abroad in relation to self-efficacy perceptions and beliefs. Data sources included in-depth three-way interviews, field observations, and student artifacts. Inductive analysis guided the highlight of significant statements and the creation of clusters and themes; cross-case analyses allowed for a thorough analysis and aided the in-depth description of the essence of the phenomenon at hand for each case.

  • 10. Shook, Allan The Effect of Cardiac Rehabilitation on 30-Day Hospital Readmission Rates

    PHD, Kent State University, 2015, College of Education, Health and Human Services / School of Health Sciences

    Readmission rates at 30 days are considered a hospital quality indicator, and previous research suggests that up to 76% of 30-day readmissions could be prevented. The purpose of this study was to compare 30-, 60-, and 180-day readmission and short-term observation (STO) rates for participants and non-participants in Phase II cardiac rehabilitation (CR), and to determine predictors for readmission, STO and CR participation. Ninety subjects (participants n = 45; non-participants n = 45) retrospectively participated in the study. All subjects were referred to CR following a qualifying diagnosis. An additional 131 subjects were retrospectively studied to quantify predictors for readmission, STO, and participation in CR. Thirty-day readmission rates approached statistical significance and were higher for non-participants than participants (p = .064). Sixty-day readmission rates were higher for non-participants but not statistically significant. One hundred eighty-day readmission rates were significantly higher for non-participants than participants (p = .014). Thirty- and 60-day STO rates were slightly higher for non-participants but not statistically significant. One hundred eighty-day STO rates were statistically higher for participants than non-participants (p = .027). Predictors for readmission and STO were varied, based on timeframe. Being smoke-free, non-hypertensive, married, and not having a myocardial infarction (MI) at admission were significant predictors for enrolling in CR. CR appears to decrease the likelihood for readmission at 180 days. STO rates were higher at 180 days for CR participants, perhaps indicating a need for increased monitoring without rehospitalization. Predictors for readmission and STO were widely varied, necessitating further research.

  • 11. Hamed, Fawzi Language Tension, Terminology Variation and Terminology Policy in the Arabic-Speaking North African Countries: An Alternative Approach to Terminology Practice

    PHD, Kent State University, 2014, College of Arts and Sciences / Department of Modern and Classical Language Studies

    This study is concerned with examining this multilingual situation in the Arabic-Speaking North African countries (ANAC) and its social, scientific and political impact on terminology policy (TP). It is based on the hypothesis that two factors are behind the phenomenon of term variation and term formation. The first is the influence of foreign languages, mainly English and French, and the second is the influence of local dialects. The numerous regional dialects and the hegemony of foreign languages are likely to affect technical term formation and use. To test these hypotheses, the study addresses the current issues in implementing an effective TP in the ANAC region in particular and in the AW in general. This investigation is accompanied by an examination of terminological variation in context. Terminological variation can be basically defined as the use of alternative linguistic forms that express one specialized concept. It includes many different phenomena (e.g., orthographic variation, lexical variation, morphological variation, reduction, permutation, and short forms). The study uses a corpus-based approach to terminology. This approach supports the observation of term variation and allows comparison of Arabic texts from the specialized subject field of computers and the Internet so as to extract valuable information about how TP can be effectively implemented for terminology standardization purposes.

  • 12. He, Yuanlong Relationship between Firm's PE Ratio and Earnings Growth Rate

    PhD, University of Cincinnati, 2012, Business: Business Administration

    This study reexamines the relationship between firm's forward PE ratio and the expected earnings growth rate under the theoretical frame work of the AEG model (Ohlson and Juettner-Nauroth (2005)). After controlling the cost of capital, this study identifies a positive correlation between the PE ratio and the firm's short-term expected earnings growth rate. This is contrary to previous conflicting findings about the relationship between these two variables. In addition, test shows that for firms with the same cost of capital and short-term earnings growth rate, the higher the long-term abnormal earnings growth rate, the higher the PE ratio. Moreover, for those firm observations with a short-term earnings growth rate equal or close to the firm's cost of capital, the positive correlation between PE and short-term earnings growth rate is reversed and becomes negative, consistent with the conclusion from the theoretical model. Lastly, the results from the multivariable regression analysis indicate that there are several interaction relationships among variables: a significant and negative correlation between the PE ratio and cost of capital, a significant and negative correlation between the PE ratio and the difference between the cost of capital and long-term abnormal earnings growth rate, and a significant and positive correlation between the PE ratio and the difference between the firm's short-term earnings growth rate and long-term abnormal earnings growth rate.

  • 13. Kim, So-Yun The effect of long-term care insurance on the first nursing home entry and home care use: using duration analysis

    Doctor of Philosophy, The Ohio State University, 2009, Family Resource Management

    The main purpose of this study was to examine whether Long-Term Care Insurance (LTCI) ownership causes moral hazard in the Long-Term Care (LTC) market. By accounting for the endogeneity of LTCI ownership and LTC utilization, this study explored the unbiased effect of LTCI ownership on LTC utilization using duration analysis. In addition, this study presented the determinants of LTCI purchase and those of first LTC use of the elderly.Using the longitudinal data from 1998-2004 HRS (Health and Retirement Study), the first LTC use among the elderly who are 65 and older were analyzed. Two duration models were employed accounting for the endogeneity of LTCI purchase and LTC use: Cox model used lagged LTCI values and the discrete time model used the LTCI values predicted in the two-stage estimation. Findings from the two models were very consistent. Based on the two-period utility model, this study estimated LTCI purchase and first LTC use. As for LTCI purchase, the elderly with higher income and non-housing assets were more likely to buy LTCI. Denying the concern of adverse selection in the LTCI market, those who had poor health conditions were less likely to buy LTCI. And those who had informal caregivers were less likely to purchase LTCI, implying that informal care and formal LTC are substitutes. LTCI ownership increased the use of nursing home care, indicating some moral hazard in the nursing home care. And no moral hazard was found in the home care market. Medicaid eligibility significantly increased LTC use, while income and non-housing assets had negligible effect on LTC utilization, suggesting that financial resources are not important factors that determine LTC use. In addition, health limitations substantially increased LTC use, and availability of informal caregivers decreased the probability of using LTC. With the findings that LTCI ownership would not generate substantial moral hazard in the LTC market, this study provideed evidences to support the policy ini (open full item for complete abstract)

  • 14. Aroskar, Nisha Essays on the term structure of interest rates

    Doctor of Philosophy, The Ohio State University, 2003, Economics

    This dissertation contributes to the study of the term structure of interest rates by addressing some of the gaps in this literature. The term structure is an important channel of monetary transmission. It also contains information about the intertemporal choices made by economic agents. The expectations Hypothesis is the primary explanation in economics that links short term interest rates to long term interest rates. In the first essay I extend the literature by examining the expectations hypothesis in the newly developed financial markets. I find that the expectations theory is not rejected in these markets. This evidence is in sharp contrast to the evidence earlier presented for industrialized countries. Further, contrary to the simple expectations theory, the term premium has high persistence, which is reflected in significantly autoregressive error terms. The evidence also supports the longstanding suggestion that the term premium could be related to the liquidity in the economy. The next essay investigates the forecasting ability of the term spread for future output growth. There appears to be a sharp decline in the predictive power of the term spread in countries that have adopted monetary policy with a stronger response to inflation. To explore the underlying economic reasons for these findings, I explicitly model the information content of the term spread for future output growth based on a structural model. Model calibrations suggest that the forecasting ability of the term spread changes with a change in the persistence and the variance of the underlying economic shocks and in the monetary policy preferences. The last essay focuses on the term structure as a link between short term and long term interest rates in macroeconomic models. I integrate the New Keynesian model and the model of the term structure based on the Intertemporal Consumption Asset Pricing Model. This is a more plausible description of the economy compared to the earlier models. In this (open full item for complete abstract)

    Given the rapidly changing world of long-term care and the evolving role of administrators and the regulatory standards they are required to meet, it is not clear what new administrators coming into the field need to know to practice effectively. The purpose of this study is to learn out what people entering the field of long-term care administration need to know from licensed administrators. This qualitative study used a three-pronged approach to examine: required curriculum for administrators (Core of Knowledge, Administrator in Training, and licensure testing), relevant texts on effective long-term care administration, and advice about effective practices from seasoned administrators. Seven administrators participated in in-depth interviews. Findings indicate that administrators felt they lacked knowledge in many key areas including: knowing the scope of what the job entails, personnel management, financial management, and documentation. They also stressed that love of older residents was a key component of job success.

    Master of Gerontological Studies, Miami University, 2010, Gerontology

    This study analyzes expected nursing home use, and particularly the ways in which family structure is related to expectations. Using data from the 2006 Health and Retirement Study, I use multiple regression analysis to examine how measures of family structure (including daughters and sons, household structure, proximity to family, and previous and current marital status) are related to perceived nursing home risk. Results show that being female, age, ADL limitations, and having long term care insurance are related to increased expectation of use, while subjective health, having a parent or child in the household, or having a daughter are related to decreased expectations of use. Although several factors are related to expectations of nursing home use in ways consistent with actual use, marital status, having living brothers and sisters, and having local family are not significantly related to expected nursing home use. Policy implications of the findings are discussed.

    In 1980 the proportion of the population in Korea aged 65 and over was only 3.0%. By 2000, that proportion had jumped to 7.2% and is expected to be 24.0% in the year 2030 (Korea National Statistical Office, 2002). The challenges of this demographic shift include the ability of the government to provide an adequate long-term care program for its disabled elders. This study explores the Korean long-term care program that will start in 2008. In order to better understand the Korean long-term care program, this study examines how three other nations (Germany, Japan and the United States) deliver long-term care services and compares the underlying policy models for all four nations. This study also critically analyzes the program theory and implications of the Korean long-term care program.

    Undergraduate Honors Program, Malone University, 2025, Honors Thesis

    Bonding between a mother and infant is instrumental in creating a healthy attachment for the dyad. In the case of Neonatal Abstinence Syndrome (NAS), dyad bonding can be more difficult because of the infant's withdrawal symptoms, maternal opioid use disorder (OUD), and external factors that can influence maternal OUD and NAS diagnoses. Hospitalization directly following birth is a vital period for implementing nursing interventions that can promote bonding for the dyad early on, creating a foundation for continuation once the dyad is discharged. While several nursing interventions can assist the infant with withdrawal symptoms, the effects these interventions have on dyad bonding are not taken into consideration. This literature review will discuss the most effective nursing interventions that will support the mother and infant in dyad bonding in the context of NAS. This review will also explore the nurse's essential role in helping facilitate environments specific to healthcare settings that are conducive of dyad bonding for the mother and infant. Through understanding the influences of OUD and NAS diagnoses, the importance of dyad bonding in a mother-infant relationship, and the nurse's role in all this, healing connections can be initiated.

    Doctor of Philosophy, Miami University, 2024, Gerontology

    The COVID-19 pandemic has exposed vulnerabilities within the healthcare system, with nursing homes in under-resourced communities particularly impacted. Numerous studies have linked community socioeconomic status to both care quality and COVID-19 outcomes in these settings, suggesting that nursing homes in disadvantaged neighborhoods provide lower quality care, resulting in poorer health outcomes for residents. However, whether high-quality nursing homes can effectively reduce these health disparities remains unclear. Additionally, conventional long-term care research often overlooks spatial relationships, which can introduce bias into findings. Understanding these dynamics is essential for building resilience against future health emergencies. This study explores the relationships among neighborhood disadvantage, care quality, and COVID-19 outcomes in Ohio nursing homes, examining the potential influence of spatial relationships. While nursing homes in more disadvantaged areas generally exhibit lower quality performance, these quality metrics do not show significant associations with neighborhood socioeconomic status after adjusting for organizational factors and resident characteristics. Instead, quality performance is associated with factors like financial health (e.g., Medicaid payor mix, occupancy rates), stable in-house staffing, consistent leadership, and resident demographics. The study also reveals consistently high mortality risks among residents in nursing homes located in disadvantaged neighborhoods, which are unaffected by quality performance indicators. While COVID-19 incidence rates among residents and staff show no significant associations with neighborhood socioeconomic status, higher CMS Five-Star Staffing ratings and resident satisfaction scores significantly reduce resident COVID-19 incidence rates over the two-year pandemic period. Conversely, higher CMS Five-Star Overall, Health Inspection, and Staffing ratings are linked to increased sta (open full item for complete abstract)

  • 20. Hu, Yanchen Essays on U.S. Housing Price and Macroeconomy

    Doctor of Philosophy, The Ohio State University, 2024, Economics

    This dissertation studies the relationship between the U.S. aggregate housing price index and the macroeconomy. The contributions are two-fold. On the one hand, I quantify the effect of the aggregate housing price on the U.S. economy through two mechanisms —— the wealth channel and the collateral channel. To make the model- implied housing price dynamics more empirically appealing, I introduce two new elements into the model. First, I model the expectations of future housing price as a convex combination of conventional rational expectations and irrational extrapolations. Second, I introduce a new structural shock that perturbs the households' expectations on future housing price. On the other hand, this dissertation also makes contributions on computational algorithm. First, I formalize an algorithm that incorporates exotic information set (EIS) into a nonlinear DSGE model. Second, I develop a variant of the conventional Sequential Monte-Carlo sampling by replacing the likelihood tempering with model tempering to reduce the computational cost due to occasionally binding constraints. In the first chapter, I estimate a three-shock New-Keynesian macro-housing model aug- mented with endogenous growth and housing price extrapolation. Estimation shows that both channels are indispensable in matching the model impulse response functions (IRFs) with the empirical IRFs implied by vector autoregression (VAR). The estimated model matches well the empirical standard deviations of several key macro variables. Housing price extrapolation explains nearly 90% of housing price variance. Spillover of extrapolation into the macro business cycle exclusively occurs in the medium run. Quantitatively, the spillover effect is non-trivial and is similar in magnitude as the effect of endogenous growth. An exception is aggregate investment, where the spillover is minimal. The reason for the exception —— sectoral shift of investment from physical capital to adoption c (open full item for complete abstract)
