Software Intrusion Detection Evaluation System: A Cost-Based Evaluation Of Intrusion Detection Capability, Agbotiname L. Imoize, Taiwo Oyedare, Michael E. Otuokere, Sachin Shetty

VMASC Publications

In this paper, we consider a cost-based extension of intrusion detection capability (CID). An objective metric motivated by information theory is presented and based on this formulation; a package for computing the intrusion detection capability of intrusion detection system (IDS), given certain input parameters is developed using Java. In order to determine the expected cost at each IDS operating point, the decision tree method of analysis is employed, and plots of expected cost and intrusion detection capability against false positive rate were generated. The point of intersection between the maximum intrusion detection capability and the expected cost is selected as …

Time Dependent Attribute-Level Best Worst Discrete Choice Modelling, Amanda Working, Mohammed Alqawba, Norou Diawara, Ling Li

Mathematics & Statistics Faculty Publications

Discrete choice models (DCMs) are applied in statistical modelling of consumer behavior. Such models are used in many areas including social sciences, health economics, transportation research, and health systems research and they are time dependent. In this manuscript, we review references on the study of such models, develop DCMs with emphasis on time dependent best-worst choice and discrimination between choice attributes. Referenced measurements of the dynamic DCMs are simulated. Expected utilities over time are derived using Markov decision processes. We study attributes and attribute-levels associated with the quality of life of seniors, report the estimation results, and discuss our findings.

Should Cookie Monster Adopt A Healthy Lifestyle Or Continue To Indulge? Insights Into Brand Icons, Altaf Merchant, Kathryn A. Latour, John B. Ford, Michael S. Latour

Marketing Faculty Publications

Developing a brand icon has been a way for marketers to humanize and forge relationships with consumers. Icon development takes time. During this time, marketers have to face how much they stay true and consistent with their icons and how much they allow their icons to adapt to cultural changes in the marketplace. Little is known about how consumers respond to changing icons, and even less is known about whether there may be certain consumer groups that are more or less receptive to such changes. Four experiments and qualitative interviews were undertaken to gain insights into these issues. People who …

Evaluation Of Procurement Scenarios In One-Dimensional Cutting Stock Problem With A Random Demand Mix, Hüseyin Sarper, Nebojsa I. Jaksic

Electrical & Computer Engineering Faculty Publications

The one-dimensional cutting stock problem describes the problem of cutting standard length stock material into various specified sizes while minimizing the material wasted (the remnant or drop as manufacturing terms). This computationally complex optimization problem has many manufacturing applications. One-dimensional cutting stock problems arise in many domains such as metal, paper, textile, and wood. To solve it, the problem is formulated as an integer linear model first, and then solved using a common optimizer software. This paper revisits the stochastic version of the problem and proposes a priority-based goal programming approach. Monte Carlo simulation is used to simulate several likely …

Random Walks And Market Efficiency: Evidence From Real Estate Investment Trusts (Reit) Subsectors, Fahad Almudhaf, Andrew J. Hansz

Finance Faculty Publications

This paper investigates the random walk behavior of real estate investment trust (REIT) subsectors using monthly return data from January 1994 to July 2015. Using variance ratio tests, we examine subsectors of lodging/ resorts and self-storage and find that they do not follow a random walk, contradicting the weak-form efficient market hypothesis. Nonparametric runs tests help us find that office, industrial, mixed, free standing, shopping centers, apartments, manufactured homes, and timberland subsectors are weak-form efficient. The evidence in this study supports the idea that some subsectors are more informationally efficient than other subsectors. Copyright © 2018 The Author(s).

Toward Better Management Of Flood Losses: Flood Insurance In A Wetter World, Michael K. Mcshane, Juita-Elena (Wie) Yusuf

Finance Faculty Publications

Flood is the most frequent and costly of U.S. natural disasters with losses expected to increase due to climate change. The National Flood Insurance Program (NFIP) mandates flood insurance purchase for properties with federally backed mortgages in the 100-year floodplain. We propose that mandatory flood insurance purchase be extended to all property in the 500-year floodplain. Following flood events, payments would be directly provided for more properties that suffer flood loss, reducing federal disaster aid spending. The mandate could put more pressure on local governments to increase their Community Rating System score, such as through infrastructure investments and management practices …

Does The Market Believe White Knights And Hostile Bidders Are Acting In Their Shareholders' Interest?, John M. Griffith, Mohammad Najand, Jiancheng Shen

Finance Faculty Publications

This study examines why white knights suffer significant losses while their rival hostile bidders experience significant abnormal gains. We address two research questions: 1) Does the market believe that white knights and hostile bidders are acting in their shareholders' interest? 2) Does Tobin's q explain why white knights suffer significant losses and hostile bidders experience significant gains upon the announcement of their bids? The results show that hostile bidders are value-maximizing investors and white knights are not acting in their shareholders' interest. Instead, white knights suffered significant reductions in value and historically have not maximized the wealth of investors

Three Essays On Ceo Risk Preferences, And Ability, Corporate Hedging Decisions, And Investor Sentiment, Sonik Mandal

Does Machiavelli's The Prince Have Relevant Lessons For Modern High-Tech Managers And Leaders?, Clovia Hamilton

Management Faculty Publications

When we think of Machiavellian conduct in technology companies, we think of cut-throat, cunning, behaviour. Cut-throat competition in technological innovations can be the barrier to market entry (Lee, 2014). The lean philosophy is that managers and leaders are to strive for the efficient and effective use of resources in order to overcome this barrier and gain competitive advantage. In order for there to be cut throats, there have to be cut-throat technology innovation leaders and managers. What the lean philosophy lacks is guidance on how to achieve an efficient and effective use of resources in a cut-throat competitive environment. The …

Diversity Team Building: Impact On Virtual Team Performance, Nina C. Magpili-Smith

Engineering Management & Systems Engineering Theses & Dissertations

Although organizations have addressed diversity issues at the organizational-level with resulting positive employee outcomes, lack of scholarly attention to team-level interventions remain. Team-level interventions would benefit organizations more directly as they address issues directly related to task accomplishment. Since diversity may lead to negative performance results for teams, a team building intervention based on the latest empirical research was developed and tested to address the potential performance losses associated to diversity in decision-making teams. The team building intervention provides six crucial elements, namely (1) direct experience of how deep-level team diversity affect team dynamics, (2) diversity education, (3) cultivation of …

Threat Or Challenge? Intensified Job Demands And The Moderating Effect Of Differentiated Transformational Leadership, Benjamin Bass

Psychology Theses & Dissertations

Over the past 30 years, industrialized democracies have experienced major economic change due to globalization, economic instability, and rapid technological innovation. To remain viable, organizations maximize flexibility through strategies like downsizing, just-in-time inventory, and temporary labor. Consequently, employees face heightened responsibility, variable workloads, and rising job insecurity. While these demands are stressful, at times, some may represent an exciting challenge. Recently, researchers started studying how the long-term intensification of work affects employees via intensified job demands. This dissertation builds on their efforts by exploring short-term job demand intensification. Specifically, the transactional model of stress and the job demands-resources model were …
