Empirical Methods for Evaluating Vulnerability Models
… to independently and systematically validate empirical vulnerability models?”. Based on the survey of past studies about the vulnerability discovery process, the dissertation has pointed out several critical issues in the traditional methodology for evaluating the performance of vulnerability …

Empirical Methods for Evaluating Video-Mediated Collaborative Work
… In the second study, a collection of research methods known as ethnography was used to examine long-term use of desktop video by collaborators in a real work situation. Participants from a graduate course met each week for seven weeks and worked on a class project under one of four …

Hydrodynamic Modeling for Autonomous Underwater Vehicles Using Computational and Semi-Empirical Methods
… recharge. There is a need for the development of methods for hydrodynamic modeling. This thesis aims to determine the hydrodynamic parameters for the governing equations of motion for three autonomous underwater vehicles. This approach is two fold, using data obtained from computational flight …

Essays on the Use of Duality, Robust Empirical Methods, Panel Treatments, and Model Averaging with Applications to Housing Price Index Construction and World Productivity Growth
… specifications, as well as their implementation methods, are then discussed in detail. These representative models make different assumptions about the efficiency term, aiming to provide better approximations of the underlying data generating process without adding too many constraints. Comparing …

Access and benefit-sharing regimes concerning the utilization of plant genetic resources and traditional knowledge regarding the use of plant genetic resources: using law, economics, and empirical methods to analyze plant genetic resources issues, including biopiracy, bioprospecting, and intellectual property
The developed and developing worlds have different perspectives regarding plant genetic resources (PGRs) and traditional knowledge regarding the use of PGRs. The developed world favors intellectual property rights (IPRs), and terms the collection of PGR samples from the developing world to be …

Structuring Emperical Methods for Reuse and Efficiency in Product Development Processes
… this deficiency by testing prototypes to obtain empirical data that can be used in place of predictive models. The purpose of this work is to provide techniques and methods for efficient use of empirical methods in product development processes. Empirical methods involve the design and creation …

Estudo da estabilidade de valas escoradas por equilíbrio-limite e pelo método dos elementos finitos
… of strutted excavations by means of different methods. Chapter 2 presents a review of the methods available for the stability analysis of excavations: the methods fall into three main cathegories, namely (a) simple (or "empirical") methods, (b) limit-equilibrium methods and (c) the Finite …

Design flood peak determination in the rural catchments of the Eastern Cape, South Africa
… projects. Over the past century standard methods for flood peak estimation have been developed for most countries, and are usually categorized in the literature as direct statistical analyses, regional statistical analyses, empirical methods and deterministic methods. Some of these methods …

Economic Efficiency in the Production of Low-Volume Rural Roads: An Application of Radial Measures of Efficiency
… second was to compare and contrast alternative empirical methods used to obtain efficiency measures. The principle policy option examined was jurisdictional consolidation as a method to enhance production efficiency and reduce long-run costs.

The development of hybrid quantum classical computational methods for carbohydrate and hypervalent phosphoric systems
Ab initio, density functional theory, and semi-empirical methods serve as major computational tools for quantum mechanical calculations of medium to large molecular systems. Semi-empirical methods are most effectively used in a hybrid quantum mechanics/molecular mechanics (QM/MM) dynamics …

Towards building a theory of Lean implementation in healthcare
… outcomes of Lean implementation, there is little empirical evidence indicating which factors influence Lean implementation. Furthermore, there is an absence of critical and theory building research of Lean implementation. This study specifically addressed these gaps by identifying some of the …

Evaluation of the AASHTO Mechanistic Empirical Pavement Design Guide: an experimental and analytical investigation of the performance of flexible roads
… It reflects a shift from total reliance on empirical methods to a combination of mechanistic and empirical methods. Three instrumented road sections were used to capture the impact of local conditions. The measurements indicated that opening roads prematurely to traffic, immediately after …

Advancing Pattern Detection, Theory Development and Decision Making with Explainable AI
… of explainable artificial intelligence (XAI) methods in data-driven decision-making and computationally intensive theory development (CTD) is a subject of ongoing debate, particularly concerning how and whether these methods can be effectively employed, and how the reliability of their …

Four Essays on Managerial Incentives
… firms has declined over time using a variety of empirical methods. We use 31 years of data on corporate dividend announcements, stock split announcements, and earnings announcements for a large set of U.S. firms to investigate these topics. The investigation of the entire distributions of returns …

Essays in empirical law and economics/
… which is a collection of three essays, uses empirical methods to study questions at the intersection of law and economics. The first chapter, co-authored with Joshua Fischman, explores how supervision by an administrative appeals court, the Board of Immigration Appeals (BIA), influences the …

Accruals and managerial operating decisions over the firm life cycle
… by ignoring life cycle fundamentals, previous empirical methods would likely misclassify this variation in accruals as reflecting systematic differences in a firm's "accounting quality". I suggest empirical techniques to mitigate incorrect inferences about accounting quality and to better …

An Empirical and Comparative Analysis of UK Courts and CJEU decisions in Trademark Law: defining the nature and understanding the characteristics of inconsistencies in EU Trademark law
… that arise. <br/>Secondly, it utilises empirical methods (‘fuzzy sets’ and ‘building blocks’) as analytical tools in investigating the area of exhaustion of rights. It argues that using these empirical methods in this area offers a roadmap aimed at understanding the subset relationships …
