Statistical and causal analysis of inbound supply chain inefficiencies
… with the practical application of statistical analysis methods, a complete supplier evaluation process is established. Further, by utilizing statistical sampling and based on the evaluation results, an inspection plan is provided that allows for accurate monitoring of ongoing processes with a …

Causal Analysis of Disengagement Among Paid and Volunteer City Employees
… processes as determinants of turnover. Path analysis, tested with the Specht (1975) procedure for goodness-of-fit, determined that the Mobley model fit the volunteer data as well as it did the paid worker data but with only a low goodness-of-fit index (Q =.20 for both samples). An augmented …

Causal Analysis of a National Study of Sales Personnel Turnover Functionality
<p>A causal model of the antecedents of turnover functionality was developed and tested in a national field study of sales representatives from a Fortune 50 company. Turnover functionality was defined in terms of the difference between the performance levels of leavers and stayers in the host …

Causal Analysis Experiments on Log Extraction and Processing for Causal Insights
… systems do not necessarily inform users of the causal relationships that are inherent in the data. To this end, we design a new log-based data processing system that provides answers to causal questions based on timestamped logs. This thesis work focuses on improving the current log extraction …

A framework for testing cyber-physical systems : input generation and causal analysis
… a framework for (conformance) testing and (causality) analysis of cyber-physical systems. The framework is divided into two stages, i) a search-based testing approach that generates effective inputs for finding faults in CPSs and ii) a notion of causality that assigns causes for the events …

A weather related causal analysis on consolidated delay at Newark Liberty International Airport
… (e.g. thunderstorms) at the same airport. An analysis using temporal functionality with Bayesian Networks (BN) software and heuristic analyses was conducted. Data extracted from weather and aviation based websites was extracted using software. The quality of the information was cross …

From Logs to Causal Analysis: A Guided User Interface for Causal Graph Discovery
… in time, which can later be leveraged to answer causal questions about the system. However, analyzing logs is currently far from a smooth experience. Some system dynamics might only be partially captured by log variables, while others are drowned out by the sheer volume of uninteresting, …

Investigating the Impacts of Boston’s Fare Free Bus Route on Urban Mobility Behavior: A Framework for Causal Analysis
… impact of the fare free policy, centering its analysis on Route 28. Employing the tools of causal inference, it offers a valuable resource for planners, policymakers, and scientists seeking to analyze the effect of policy interventions through the lens of big data. Drawing on anonymized, …

Count-Regression-Based Empirical Causal Analysis from a Potential Outcomes Perspective: Accounting for Boundedness, Discreteness, Dispersion and Unobservable Confounding
… for count-regression-model-based (CRM-based) causal effect estimation in which the value for the outcome of interest is restricted to the non-negative integers. I implement first-order two-stage residual inclusion (FO-2SRI) methods, in the context of the general potential outcomes framework, …

A Causal Analysis of Achievement Models for Language Minority Students in the United States: A Linear Structural Relations (Lisrel) Approach
The purpose of the present study was to empirically test the validity of a theoretical model linking ethnic-language dominance, socio-economic status, and parental involvement to cognitive achievement and psychological orientation. An unbalanced, multi-group sample was randomly selected from the …

Causal Graph Summarization
Causal inference is critical for scientific progress, especially in social sciences like public health and education—however, analysts often only have access to partial data which may lead to erroneous conclusions if critical confounding biases are not accounted for. To do this, they critically …

Essays in Causal and Comparative Econometrics
My doctoral dissertation concerns causal and comparative econometrics. It comprises four separate essays with a common theme. They propose new metrics for causal or comparative inference and address problems with some ratios that are widely used for policy analysis. In the first chapter titled …

Safety in Hospital Medication Administration Applying STAMP Processes
Repeated application of root cause analysis techniques has not led to significant hospital medication administration safety improvements. The healthcare industry has begun to draw on scientific approaches to safety from outside traditional medical fields, including human factors engineering and …

A system theoretic approach to design safety into medical device
… China was used as a test case to study whether Causal Analysis based on STAMP (CAST) is used to outline the interactions between the different medical device system components, identify the safety control structure in place, and understand how this control structure failed to prevent artificial …

Application of Systems-Theoretic Analysis to Work Movement in Production Systems
… thesis presents the results of an application of Causal Analysis based on Systems Theory (CAST) to a loss of producibility following the movement of a production process from a supplier to an aerospace OEM. In addition to the principal analysis, background information is presented on the relevant …
