Who Survived The Titanic? A Logistic Regression Analysis, Lonnie K. Stevans, David Gleicher
Who Survived The Titanic? A Logistic Regression Analysis, Lonnie K. Stevans, David Gleicher
Lonnie K. Stevans
A logistic regression analysis of an extensive data set on the Titanic passengers is presented which tests the likelihood that a Titanic passenger survived the accident--based upon passenger characteristics. The main finding is that underneath the strong overt preference afforded in the rescue by the authorities to women and children over men, there was a complex class determination of survival rates among men, on the one hand, and women and children, on the other. We hypothesize that the statistical interactions of gender and class are explained by two crucial decisions made by the ship’s authorities: 1. to encourage, and perhaps …
The Importance Of Marketing And Total Quality Management In Libraries, Rajashekhar D. Kumbar
The Importance Of Marketing And Total Quality Management In Libraries, Rajashekhar D. Kumbar
E-JASL 1999-2009 (Volumes 1-10)
Introduction
Herb White, states in Library Journal, “... it should be fairly clear that librarians do not market and that they never have marketed.” He concludes, “What we need to tell people is not how wonderful our public libraries are but rather how wonderful they could be. The awakening of these dreams is the purpose of marketing” (Besant & Sharp, 2000). Since the 1960’s, the most widely taught marketing concept was the marketing mix theory: the 4Ps (product, price, place and promotion)—so clean, so neat, so inappropriate for libraries. Marketing theory cannot always be so succinctly described since relationships …
Technical Note: Comparative Static Analysis Of Information Value In A Canonical Decision Problem, Jeffrey Keisler
Technical Note: Comparative Static Analysis Of Information Value In A Canonical Decision Problem, Jeffrey Keisler
Management Science and Information Systems Faculty Publication Series
To gain insight into the behavior of the value of information, this paper identifies specific rules for a canonical decision problem: the two-act linear loss decision with normal prior probability distributions. Conditions are derived for which the expected value of perfect information increases when mean and standard deviation are both linear functions of an exogenous variable. A variety of richer decision problems can be adapted to the problem, so that the general results obtained here can be immediately applied to understand drivers of information value.
Interest Rate Parity In Excel, Tom Arnold, Bonnie Buchanan
Interest Rate Parity In Excel, Tom Arnold, Bonnie Buchanan
Finance Faculty Publications
This paper develops interest rate parity in a framework that is easily implemented in Excel. The student can either be given the paper to see how the code is developed using the intuition of the interest rate parity framework or the student can be taught the interest rate parity framework and develop the Excel code as an assignment. Using either teaching method or the other exercises suggested in the paper, the student is able to understand how traders exploit violations of interest parity and become more comfortable with basic concepts, such as direct quotes and indirect quotes.
Chaos-Induced Escape Over A Potential Barrier, L. Y. Chew, Hian Ann, Christopher Ting, C. H. Lai
Chaos-Induced Escape Over A Potential Barrier, L. Y. Chew, Hian Ann, Christopher Ting, C. H. Lai
Research Collection Lee Kong Chian School Of Business
We investigate the statistical parity of a class of chaos-generated noises on the escape of strongly damped particles out of a potential well. We show that statistical asymmetry in the chaotic fluctuations can lead to a skewed Maxwell–Boltzmann distribution in the well. Depending on the direction of skew, the Kramers escape rate is enhanced or suppressed accordingly. Based on the Perron–Frobenious equation, we determine an analytical expression for the escape rate’s prefactor that accounts for this effect. Furthermore, our perturbative analysis proves that in the zeroth-order limit, the rate of particle escape converges to the Kramers rate.

Allocating Contractor Risks In The Hanford Waste Cleanup, Jeffrey M. Keisler, William A. Buehring, Peter D. Mclaughlin, Mark A. Robershotte, Ronald G. Whitfield
Management Science and Information Systems Faculty Publication Series
Organizations may view outsourcing as a way to manage risk. We developed a decision-analytic approach to determine which risks the buyer can share or shift to vendors and which ones it should bear. We found that allocating risks incorrectly could increase costs dramatically. Between 1995 and 1998, we used this approach to develop the request for proposals (RFP) for the US Department of Energy’s (DOE’s) privatization initiative for the Hanford tank waste remediation system (TWRS). In the model, we used an assessment protocol to predict how vendors would react to proposed risk allocations in terms of their actions and their …

Obesity, Educational Attainment, And State Economic Welfare, Martin W. Sivula Ph.D.
MBA Faculty Conference Papers & Journal Articles
For the first time in history, estimates of the overweight people in the world rival estimates of those malnourished. The World Health Organization (WHO, 2002) ranked obesity among the top 10 risks to human health worldwide. In the early 1960s, nearly half of the Americans were overweight and 13% were obese. Today some 64% of U.S. adults are overweight and 30.5% are obese. Even more alarming, twice as many U.S. children are overweight than were twenty years ago, a 66% increase. Non-communicable diseases impose a heavy economic burden on already strained health systems. Health is a key determinant of development …

Reinventing Leadership: Blended Dualism, Andrew Sikula Sr., Chong W. Kim
Reinventing Leadership: Blended Dualism, Andrew Sikula Sr., Chong W. Kim
Management Faculty Research
Leadership needs to be redefined and explained differently in terms of what we have learned about organizational directorship during the last few decades. In addition to a new definition, a post twentieth century model of leadership needs created with steps and parameters opposite from pre-2000 thinking and philosophy. This article presents a new leadership definition and model, plus it identifies leadership parameters, steps, and lessons. Furthermore, it introduces a new concept into management/leadership/organization literature called Blended Dualism which incorporates the very latest supervisory thinking into a holistic, integrated amalgam of what initially appears to be contradictory or at least paradoxical …
Solving Hierarchical Constraints Over Finite Domains With Local Search, Martin Henz, Roland H.C. Yap, Yun Fong Lim, Seet Chong Lua, J. Paul Walser, Xiao Ping Shi
Solving Hierarchical Constraints Over Finite Domains With Local Search, Martin Henz, Roland H.C. Yap, Yun Fong Lim, Seet Chong Lua, J. Paul Walser, Xiao Ping Shi
Research Collection Lee Kong Chian School Of Business
Many real world problems have requirements and constraints which conflict with each other. One approach for dealing with such over-constrained problems is with constraint hierarchies. In the constraint hierarchy framework, constraints are classified into ranks, and appropriate solutions are selected using a comparator which takes into account the constraints and their ranks. In this paper, we present a local search solution to solving hierarchical constraint problems over finite domains (HCPs). This is an extension of local search for over-constrained integer programs WSAT(OIP) to constraint hierarchies and general finite domain constraints.The motivation for this work arose from solving large airport gate …

Measuring Cognitive Ability With The Overclaiming Technique, Delroy L. Paulhus, Peter D. Harms
Measuring Cognitive Ability With The Overclaiming Technique, Delroy L. Paulhus, Peter D. Harms
Leadership Institute: Faculty Publications
The overclaiming technique requires respondents to rate their familiarity with a list of general knowledge items (persons, places, things). Because 20% of the items are foils (i.e., do not exist), the response pattern can be analyzed with signal detection methods to yield the accuracy and bias scores for each respondent. In Study 1, the accuracy index showed strong associations with two standard IQ tests (β = .50–.59). Study 2 replicated the validity of the accuracy index with IQ and showed coherent associations with school grades, peer ratings, and self-ratings. Study 3 ensured that the validity of the accuracy index is …
A Paradigm For Spreadsheet Engineering Methodologies, Thomas A. Grossman Jr., O Ozluk
A Paradigm For Spreadsheet Engineering Methodologies, Thomas A. Grossman Jr., O Ozluk
Business Analytics and Information Systems
Spreadsheet engineering methodologies are diverse and sometimes contradictory. It is difficult for spreadsheet developers to identify a spreadsheet engineering methodology that is appropriate for their class of spreadsheet, with its unique combination of goals, type of problem, and available time and resources. There is a lack of well-organized, proven methodologies with known costs and benefits for well-defined spreadsheet classes. It is difficult to compare and critically evaluate methodologies. We present a paradigm for organizing and interpreting spreadsheet engineering recommendations. It systematically addresses the myriad choices made when developing a spreadsheet, and explicitly considers resource constraints and other development parameters. This …
Aggregate Consumption Spending, The Stock Market, And Asymmetric Error Correction, Lonnie K. Stevans
Aggregate Consumption Spending, The Stock Market, And Asymmetric Error Correction, Lonnie K. Stevans
Lonnie K. Stevans
In this study, we show how changes in wealth resulting from unanticipated changes in the value of equity holdings begin a process whereby households alter consumption growth in order to close the gap between actual and target spending. Because of changing uncertainty or equity price volatility over the stock market cycle, we found the time path of this adjustment to exhibit near random walk behavior during stock market downturns. Conversely, during “boom” periods, e.g. when the value of equities held by households was greater than the threshold, the growth in consumer spending was quick to eliminate the disparity between actual …
The Creation And Growth Of Ict Based Industrial Clusters: The New Zealand Case, Malcolm J. Fraser, Stephen Kelly
The Creation And Growth Of Ict Based Industrial Clusters: The New Zealand Case, Malcolm J. Fraser, Stephen Kelly
Malcolm Fraser
This paper provides an exploratory review of current global research on industrial clusters, and seeks to identify the key success components of these clusters. It then discusses these attributes in terms of their implication for New Zealand ICT industrial clusters. It is argued that by reviewing the success attributes underpinning industrial clusters a baseline can be established for decision-making in both the commercial activities of industry vertical groups, as well as local/central government economic policy formulation. The paper identifies the key success factors as the presence of large pillar firms that intact with strong local demand via a sophisticated work …

Teaching Decision Making With Baseball Examples, J. Eric Bickel
Eric Bickel
Sports examples can be wonderful vehicles for teaching OR/MS concepts. Baseball is particularly well suited to teaching statistics/probability, Markov decision processes, and decision analysis. This paper details a baseball example I developed to teach fundamental decision making skills. This example has been used successfully to teach decision making to undergraduates and graduates in technical and non-technical disciplines. It has also been used effectively in industry for training new MBAs and seasoned executives.

Effective Work Practices For Software Engineering: Free/Libre Open Source Software Development, Kevin Crowston, Hala Annabi, James Howison, Chengetai Masango
School of Information Studies - Faculty Scholarship
We review the literature on Free/Libre Open Source Software (FLOSS) development and on software development, distributed work and teams more generally to develop a theoretical model to explain the performance of FLOSS teams. The proposed model is based on Hackman's [34] model of effectiveness of work teams, with coordination theory [52] and collective mind [79] to extend Hackman's model by elaborating team practices relevant to effectiveness in software development. We propose a set of propositions to guide further research.

Estimation Of Complete Period Life Tables For Singaporeans, Siu-Hang Li, Wai-Sum Chan
Estimation Of Complete Period Life Tables For Singaporeans, Siu-Hang Li, Wai-Sum Chan
Journal of Actuarial Practice (1993-2006)
Complete period life tables, with death rates for every year of age, are not available in Singapore. This study constructs such tables for Singaporeans from the limited mortality information contained in the abridged life tables provided by the Singapore Department of Statistics. We find that linear interpolation, Whittaker graduation, and the Coale-Kisker method together can generate complete life tables that are smooth and continuous. The validity of the complete life tables generated by our method is further confirmed by (1) comparing the life expectancies calculated from our estimated life tables with those provided by the Singapore Department of Statistics, and …
Rapid Calculation Of The Price Of Guaranteed Minimum Death Benefit Ratchet Options Embedded In Annuities, Eric R. Ulm
Rapid Calculation Of The Price Of Guaranteed Minimum Death Benefit Ratchet Options Embedded In Annuities, Eric R. Ulm
Journal of Actuarial Practice (1993-2006)
This paper presents a new method of obtaining quick and accurate values and deltas for discrete look back options using Taylor series expansions. This method is applied to the case of ratchet guaranteed minimum death benefits attached to annuity contracts, and the method is extended to include annuities where a fixed fund is attached to the variable account. Finally, both the speed and the accuracy of the method are compared to Monte Carlo simulation and the exact analytic solution. The Taylor expansion method is shown to be faster and, in most cases, more accurate than the alternative methods.
Approximating The Bias And Variance Of Chain Ladder Estimates Under A Compound Poisson Model, Janagan Yogaranpan, Sue Clarke, Shauna Ferris, John Pollard
Approximating The Bias And Variance Of Chain Ladder Estimates Under A Compound Poisson Model, Janagan Yogaranpan, Sue Clarke, Shauna Ferris, John Pollard
Journal of Actuarial Practice (1993-2006)
We consider the problem of estimating the outstanding claims produced by a homogeneous general insurance portfolio. The specific model considered in this paper is one where the number of claims in any loss period follows a Poisson distribution, settlement delays follow the same multinomial distribution, and settlements are single lump sums that are independent identically distributed random variables. Simulations using this model reveal that the development ratios and the outstanding claims estimates produced using the chain ladder method are positively biased. We obtain approximate formulas for the biases using Taylor series expansions of the random variables about their means. The …

Phased Retirement For Defined Benefit Plan Participants, Patricia L. Scahill, Jonathan Barry Forman
Journal of Actuarial Practice (1993-2006)
The demographic makeup of the U.S. workforce is changing. The population between ages SS and 64 is projected to increase significantly by 2020, but employment rates for this age group have not been increasing. Employers will likely need to encourage critical employees in this age group to delay retirement. Phased retirement is one tool for delaying retirement, while also not continuing full-time employment, so it can be a compromise for employers and employees. Both Congress and two administrative agencies have begun to consider changes in pension laws and regulations that would be needed to accommodate phased retirement for employers who …
Building Relationships That Last: Integrating Public Relations Into Web Design, Richard V. Mccarthy, Jay E. Aronson, Robert Petrausch
Building Relationships That Last: Integrating Public Relations Into Web Design, Richard V. Mccarthy, Jay E. Aronson, Robert Petrausch
Journal of International Technology and Information Management
This paper explores the relationship between web site design, public relations strategy, and a consumer’s intention to return to a web site. This relationship is defined through a model that explores the influence of information satisfaction, particularly when the web site design is congruent with the consumer’s expectations. The public relations dimension extends the consumer web site design model by interjecting a long-term focus on relationship building that organizations will need to make electronic commerce a viable investment in information technology resources. This is significant because it recognizes the importance of developing loyalty and trust online.
Deciding On The Appropriateness Of B2b Reverse Auction Technology Adoption: An Ahp Approach Combined With Integer Programming, Tobias Schoenherr
Deciding On The Appropriateness Of B2b Reverse Auction Technology Adoption: An Ahp Approach Combined With Integer Programming, Tobias Schoenherr
Journal of International Technology and Information Management
Although Business-to-Business online reverse auctions have emerged as a promising purchasing tool, no research has been found that provides a model to assess the reverse auction decision in a systematic way. This paper fills this gap by presenting an integrated approach, utilizing Analytic Hierarchy Process techniques and an Integer Programming Formulation, to decide whether Reverse Auction Technology (RAT) adoption is cost-effective and appropriate. The model developed is a practical decision support tool that allows for the consideration of both qualitative and quantitative decision factors, and for the adoption of multiple modes of RATs, which are contrasted to traditional purchasing.

Journal of International Technology and Information Management
This paper proposes an enterprise modeling framework for the deployment of data warehouses. The framework provides the information roadmap coordinating source data and different data warehouses across the business enterprise. The paper introduces a solution to address data warehousing issues at the enterprise level while avoiding the pitfalls of creating enterprise data warehouses and universal data marts. It further proposes a change of paradigm from point solutions focus to a methodology driven by enterprise requirements to meet the challenges of the new economy. The proposed framework emphasizes the separation of the conceptual construct from the physical and operational constructs of …

Web-Services – The Next Evolutionary Stage Of E-Business, Santosh S. Venkatraman
Journal of International Technology and Information Management
Web-Services are a set of new technologies that promise to take “service-oriented” distributed computing to a whole new level, and eventually take e-business to the next evolutionary stage. Web-Services, in a nutshell, let organizations bridge communication gaps among their information systems, and build new software applications by “stitching” together existing ones. It is capable of integrating applications written in different programming languages, developed by different vendors, and running on different servers with dissimilar operating systems. Web- Services would enable companies to seamlessly connect their information systems and business processes with those of their partners and customers – thus ushering in …
A Study Of The Relationship Between Internet Diffusion And Culture, Ravi Nath, N.R. Vasudeva Murthy
A Study Of The Relationship Between Internet Diffusion And Culture, Ravi Nath, N.R. Vasudeva Murthy
Journal of International Technology and Information Management
The unevenness in the diffusion rates of the Internet across nations is commonly referred to as the “digital divide.” Technological, economic and political factors are often mentioned as the primary contributing factors to this digital gap. However, there is sufficient evidence in support of the proposition that a nation’s culture also plays a role in how citizens adopt and use technology innovations. This paper examines the relationship between the cultural dimensions proposed by Hofstede and the Internet adoption rate of nations. Data from sixty-two countries are used to establish a regression model and the empirical results show that cultural traits …

Fee -Based Online Services : Exploring Consumers’ Willingness To Pay, L. Richard Ye, Yue Zhang, Dat-Dao Nguyen, James Chiu
Journal of International Technology and Information Management
Many online service businesses are beginning to charge fees for services that they used to provide for free. It is unclear whether consumers are ready to embrace this practice. This study explores consumer attitudes toward fee-based online services. The results of the study indicate that consumers’ willingness to pay for online services is likely to be influenced by their perceived value of convenience these services provide, and by the extent to which they utilize these services. While consumers appear more willing to pay for services that are qualitatively better than free services, there is also indication that the belief remains …
A Conceptual Framework For E-Branding Strategies In The Non-Profit Sector, Horst Treiblmaier, Irene Pollach, Arne Floh
A Conceptual Framework For E-Branding Strategies In The Non-Profit Sector, Horst Treiblmaier, Irene Pollach, Arne Floh
Journal of International Technology and Information Management
E-branding provides non-profit organizations (NPOs) with new opportunities to communicate their missions, which is of paramount importance in a market segment that competes for donations and voluntary labor. Since successful e-branding is determined by both internal and external communication strategies, we developed a framework which explains the interdependency of these two factors in NPOs. Our findings are based on qualitative interview data and a website analysis of eleven Austrian NPOs. The NPOs' internal and external e-communication strategies are categorized into three successive levels each and combined in a two-dimensional grid, which shows how NPOs integrate their communication strategies.
