Using Matching Methods From Both Fisher's Experimental Design and Rubin's Causal Model to Compare Between Two Medical Facilities with Extremely Skewed Number of Subjects
… either in inpatient rehabilitation facilities (IRFs) or in skilled nursing facilities (SNFs). Due to inclusion and exclusion criteria, however, the study had failed to recruit sufficient number of participants between two comparison groups: 319 from IRFs and 27 from SNFs. As a result, the main …

Role of Intrinsic and Reflexive Dynamics in the Control of Spinal Stability
… and nonparametric impulse response functions (IRFs) calculated in three separate studies in an effort to: 1) Quantify the effective dynamics (stiffness, damping, mass) of the trunk Nonparametric IRFs were implemented to estimate the dynamics of the trunk during active voluntary trunk extension …

Learning Structures : fusing deconvolution-based seismic interferometry with Bayesian inference for structural health assessment
… that represent the impulse response functions (IRFs) with respect to a reference excitation source. Using the deconvolved waveforms, key structural characteristics that correspond to the current state of the structure (e.g., shear wave velocity) can be extracted. Changes in these features can be …

A transcriptomic approach for studying the activation of dendritic cells in response to mycobacterial infections
… infection. Interferon Regulatory Factors (IRFs) and NFkB (Nuclear Factor kappa B) appear to be the principal transcription factors involved in regulating the cellular responses in M. tuberculosis infected BMDCs. It has been found that IRFs can function independent of the adaptor MyD88 …

THE ROLE OF IL-¿¿1 RECEPTOR-¿¿ASSOCIATED KINASE 4 IN MICROGLIAL ACTIVATION IN ALZHEIMER’S DISEASE
… work implicated the interferon response factors (IRFs) in controlling the microglial response to A¿¿ that is, in part, regulated by IRAK4 kinase activity. Analysis of whole brain homogenates revealed significant reductions in the proinflammatory IRF5 and increases in the anti-¿¿inflammatory IRF4 …

Essays on finance, learning, and macroeconomics
… asymptotically normal only when the horizon of IRFs being matched grows slowly enough. We use simulations to evaluate the performance of the common IRFME in a practical example, and we compare it with an infrequently used bias corrected approach, based on indirect inferences. Our findings …

Examination of the effects of macroeconomic shocks on the Namibian economy
… fiscal policy shocks through the SVAR approach. IRFs results reveal that a positive spending shock immediately increases output and interest rates while decreasing inflation. A positive tax revenue shock increases inflation two years after impact while decreasing interest rates at impact. …

Understanding sewer infiltration and inflow using impulse response functions derived from physics-based models
… responses, called Impulse Response Functions (IRFs), are evaluated. I&I estimation using the three IRFs, calibrated using a genetic algorithm (GA), was performed on a catchment in the Chicago area at the sewershed scale. Results are compared with one of the most widely used I&I estimation …

Essays in Macroeconomics
… output expectations to construct counterfactual IRFs. Counterfactual IRFs allow us to ask how the economy would have responded to a government spending shock holding inflation or output expectations fixed. This exercise reveals that output expectations are the key driver in the transmission of …

Three essays about the evolution and relation of SAARC countries’ agricultural production
… model (VECM) and impulse response functions (IRFs) are employed to examine the short- and long-run direction of causality and the effect of responses between energy consumption and the three sectoral outputs. The empirical results reveal that the long-run equilibrium relationship between …

Do prices drive commercial trader positions in grains and oilseeds markets?
… The results from Impulse Response Functions (IRFs) retrieved from the SVAR confirm the role of futures price changes in driving position changes, shedding new light on whether commercial traders hedge or instead speculate.

Towards realisation of stable oil prices: an empirical analysis of the impact of OPEC's oil price band/stabilisation policies.
… causality tests, impulse response functions (IRFs) and forecast error variance decompositions (FEVDs) were obtained from the VAR estimates to enable a critical analysis to be undertaken of the complex dynamics at play between OPEC and other key market players. The major contributions of the …

Marginal income tax rates and the U.K. economy: three essays
… AMTR by studying the impulse response functions (IRFs) derived from the VAR and structural VAR (SVAR) approaches. The first essay focuses upon the calculation of the AMTR in the U.K. by using the methodologies of Seater (1982, 1985) and Barro and Sahasakul (1983, 1986). The second essay uses a VAR …

Essays in Earnings Management

Innate Immune Transcription Activator Interferon Regulatory Factor-3 (IRF3) Contributes to Maladaptive Remodeling Post-myocardial Infarction
… this process. Several key findings suggest that IRFs contribute to both cell growth and apoptosis, thus providing an appealing, and novel target for interrogation. In this thesis I describe how IRF3 contributes to maladaptive remodeling post-MI. In my first set of experiments, I demonstrate that …
