The Effects Of Electricity Pring On Phev Competitiveness, Shisheng Huang, Bri-Mathias S. Hodge, Farzad Taheripour, Joseph F. Pekny, Gintaras V. Reklaitis, Wallace E. Tyner Dec 2010

The Effects Of Electricity Pring On Phev Competitiveness, Shisheng Huang, Bri-Mathias S. Hodge, Farzad Taheripour, Joseph F. Pekny, Gintaras V. Reklaitis, Wallace E. Tyner

PPRI Digital Library

Plug-in Hybrid Electric Vehicles (PHEVs) will soon start to be introduced into the transportation sector, thereby raising a host of issues related to their use, adoption and effects on the electricity sector. Their introduction has the potential to significantly reduce carbon emissions from the transportation sector, which has led to government policies aimed at easing their introduction. If their wide-spread adoption is set as a target it is imperative to consider the effects of existing policies that may increase or decrease their adoption rate. In this study, we present a micro level electricity demand model that can gauge the effects …

The Effects Of Leadership Style On Employee’S Perception Of Justice: The Role Of Employee’S Participation, Wai Kwan (Elaine) Lau Nov 2010

The Effects Of Leadership Style On Employee’S Perception Of Justice: The Role Of Employee’S Participation, Wai Kwan (Elaine) Lau

Accounting Faculty Research

The present research examines the effect of leadership style (classical, transactional, transformational, and dynamic) and employee’s participation on employee’s perception of justice (distributive, procedural, and interactional justice). It is proposed that different leadership styles are expected to display different effects on employee’s participation and perceptions of justice. Moreover, employee’s participation in decision making process is predicated to positively influence his/her perception of justice.


Developing A Culturally Responsive Classroom Collaborative Of Faculty, Students, And Institution, Paul J. Colbert Nov 2010

Developing A Culturally Responsive Classroom Collaborative Of Faculty, Students, And Institution, Paul J. Colbert

MBA Faculty Conference Papers & Journal Articles

Culture is integral to the learning process. It is the organization and way of life within the community of students and teachers and directs the way they communicate, interact, and approach teaching and learning. Although founded in particular values and principles, the academy, like most organizations, is impacted day-to-day by its culture. Yet, the traditional higher education institution has not been designed to operate within a racially or ethnically diverse student population. The social, political, economic, and cultural forces that support the institution influence the teaching and learning environments. To better address cultural diversity in the classroom, faculty must first …


The Effects Of Leadership Style And Employee’S Participation On Perceived Justice, Wai Kwan (Elaine) Lau Oct 2010

The Effects Of Leadership Style And Employee’S Participation On Perceived Justice, Wai Kwan (Elaine) Lau

Management Faculty Research

The present study proposes and tests a model that examines the relationship between leadership style, employee’s participation, and justice perceptions. Results indicate that transactional, transformational, and dynamic leadership have positive impact on distributive, procedural, and interactional justice. Moreover, the effect of leadership style on organizational justice was indirect through employee’s participation. There are also some interesting differences across different types of leadership style and justice.


Application Of The Fractional Diffusion Equation For Predicting Market Behaviour, Jonathan Blackledge Oct 2010

Application Of The Fractional Diffusion Equation For Predicting Market Behaviour, Jonathan Blackledge

Articles

Most Financial modelling system rely on an underlying hypothesis known as the Eficient Market Hypothesi (EMH) including the famous BlackScholes formula for placing an option. However, the EMH has a fundamental flaw: it is based on the assumption that economic processes are normally distributed and it has long been known that this is not the case. This fundamental assumption leads to a number of shortcomings associated with using the EMH to analyse financial data which includes failure to predict the future volatility of a market share value. This paper introduces a new financial risk assessment model based on Levy statistics …


Modeling Initial Response: Firefighter High-Rise Access Time Simulation, Robert Till Sep 2010

Modeling Initial Response: Firefighter High-Rise Access Time Simulation, Robert Till

Publications and Research

Historically, a high-rise building has been described as one which (1) was taller than the reach of fire
service apparatus and, therefore, required interior firefighting, (2) posed the potential for significant
stack effect (vertical interior smoke movement), and (3) required unreasonable time for occupant
evacuation. High-rise buildings require firefighters to access the building and travel to an upper fire
floor by using either stairs or elevators. The fire continues to grow during the time needed to apply
water on the fire. This paper demonstrates ways for using Discrete Event Simulation (DES) to estimate
the time for firefighters to access a …


Choosing Management Information Systems As A Major: Understanding The Smifactors For Mis, Thomas W. Ferratt, Stephen R. Hall, Jayesh Prasad, Donald E. Wynn Aug 2010

Choosing Management Information Systems As A Major: Understanding The Smifactors For Mis, Thomas W. Ferratt, Stephen R. Hall, Jayesh Prasad, Donald E. Wynn

MIS/OM/DS Faculty Publications

Given declining management information systems (MIS) enrollments at our university, we seek to understand our students‘ selection of a major. Prior studies have found that students choose a major based on a number of factors, with subject matter interest consistently being most important. We contribute to the literature by developing a deeper understanding of what is meant by subject matter interest, which we refer to as smiFactors, for MIS as a major and career. Based on a qualitative analysis of open-ended survey questions completed by undergraduate business students, we confirm a number of smiFactors for MIS gleaned from recent studies …


Voter Bias In The Associated Press College Football Poll, B. Jay Coleman, Andres Gallo, Paul Mason, Jeffrey W. Steagall Aug 2010

Voter Bias In The Associated Press College Football Poll, B. Jay Coleman, Andres Gallo, Paul Mason, Jeffrey W. Steagall

Management Faculty Publications

We investigate multiple biases in the individual weekly ballots submitted by the 65 voters in the Associated Press college football poll in 2007. Using censored tobit modeling, we find evidence of bias toward teams (1) from the voter’s state, (2) in conferences represented in the voter’s state, (3) in selected Bowl Championship Series conferences, and (4) that played in televised games, particularly on relatively prominent networks. We also find evidence of inordinate bias toward simplistic performance measures – number of losses, and losing in the preceding week – even after controlling for performance using mean team strength derived from 16 …


Insourcing: Reversing American Outsourcing In The New World Economy, Andrew Sikula Sr., Chong W. Kim, Charles K. Braun, John Sikula Aug 2010

Insourcing: Reversing American Outsourcing In The New World Economy, Andrew Sikula Sr., Chong W. Kim, Charles K. Braun, John Sikula

Management Faculty Research

The article discusses the need to understand the pendulum swing of human resource between insourcing and outsourcing work effort and accomplishment. The strengths of insourcing, or the use of labor within national boundaries to sustain the functions of an organization, is said to include efficient communication within the organization, enhanced employee morale and loyalty, and a high degree of control over people and resources. It is believed that there would be a resurgence of insourcing in the U.S., mainly within the government sector.


Re-Solving Stochastic Programming Models For Airline Revenue Management, Lijian Chen, Tito Homem-De-Mello Jun 2010

Re-Solving Stochastic Programming Models For Airline Revenue Management, Lijian Chen, Tito Homem-De-Mello

MIS/OM/DS Faculty Publications

We study some mathematical programming formulations for the origin-destination model in airline revenue management. In particular, we focus on the traditional probabilistic model proposed in the literature. The approach we study consists of solving a sequence of two-stage stochastic programs with simple recourse, which can be viewed as an approximation to a multi-stage stochastic programming formulation to the seat allocation problem. Our theoretical results show that the proposed approximation is robust, in the sense that solving more successive two-stage programs can never worsen the expected revenue obtained with the corresponding allocation policy. Although intuitive, such a property is known not …


The Impact Of Positivity And Transparency On Trust In Leaders And Their Perceived Effectiveness, Steven M. Norman, Bruce Avolio, Fred Luthans Jun 2010

The Impact Of Positivity And Transparency On Trust In Leaders And Their Perceived Effectiveness, Steven M. Norman, Bruce Avolio, Fred Luthans

Department of Management: Faculty Publications

A critical challenge facing today’s organizational leaders is gaining their followers’ trust and having them view leaders as effective in addressing turmoil and change. Using a downsizing scenario as the context, this field experiment examined how a leader’s positivity and transparency impacted followers’ perceived trust, defined in terms of willingness to be vulnerable, and effectiveness of their leader. To test the hypotheses, 304 participants were randomly assigned to one of the four conditions of high (low) leader positivity × high (low) leader transparency. Results of our mixed methods study indicated both the leader’s level of positivity and transparency impacted followers’ …


Exploring Social Constructions Of Followership: A Qualitative Study, Melissa K. Carsten, Mary Uhl-Bien, Bradley J. West, Jaime L. Patera, Rob Mcgregor May 2010

Exploring Social Constructions Of Followership: A Qualitative Study, Melissa K. Carsten, Mary Uhl-Bien, Bradley J. West, Jaime L. Patera, Rob Mcgregor

Leadership Institute: Faculty Publications

This study adopts a qualitative approach to deconstruct the meaning of followership. Interviews were conducted with employees in various industries to examine how individuals socially construct their roles as followers and to explore followership schemas and contextual influences that relate to these constructions. Results suggest that while some individuals socially construct definitions around passivity, deference and obedience, others emphasize the importance of constructively questioning and challenging their leaders. With regard to personal qualities that are thought to make followers effective, major themes such as obedience, expressing opinions, and taking initiative were found to be most disparate across different groups of …


Capacity-Driven Pricing Mechanism In Special Service Industries, Lijian Chen, Suraj M. Alexander May 2010

Capacity-Driven Pricing Mechanism In Special Service Industries, Lijian Chen, Suraj M. Alexander

MIS/OM/DS Faculty Publications

We propose a capacity driven pricing mechanism for several service industries in which the customer behavior, the price demand relationship, and the competition are significantly distinct from other industries. According our observation, we found that the price demand relationship in these industries cannot be modeled by fitted curves; the customers would neither plan in advance nor purchase the service strategically; and the competition would be largely local. We analyze both risk neutral and risk aversion pricing models and conclude the proposed capacity driven model would be the optimal solution under mild assumptions. The resulting pricing mechanism has been implemented at …


Managing Bpo Service Workers In India: Examining Hope On Performance Outcomes, Gwendolyn M. Combs, Rachel Clapp-Smith, Sucheta Nadkarni May 2010

Managing Bpo Service Workers In India: Examining Hope On Performance Outcomes, Gwendolyn M. Combs, Rachel Clapp-Smith, Sucheta Nadkarni

Department of Management: Faculty Publications

Much attention has been given to the explosion in business process outsourcing (BPO) operations in India. Little concern, however, has been paid to the performance of Indian service workers in these fast-paced and sometimes turbulent environments. Using a sample of 160 service workers from a privately held BPO firm in India, we examine the relationship between Indian service workers’ hope and their performance outcomes. Regression and structural equation model analyses indicated a significant positive relationship between Indian service workers’ levels of hope and their performance. These promising results highlight the importance of measuring and managing employee hope to maximize employee …


Managing Growth: Best Practices Of Family-Owned Businesses, Justin M. Andrews Apr 2010

Managing Growth: Best Practices Of Family-Owned Businesses, Justin M. Andrews

Honors Projects in Management

Family-owned businesses represent the majority of business in the United States. As consumers and employees, we are compelled to their sense of trustworthiness that all too often disappears in the business world. Our economy depends on the success of family-owned businesses, but only one third of these organizations successfully transition to the second generation and only one in ten survive to the third generation. While a series of best practices attempt to prescribe solutions their challenges, these practices fail to account for the various types of family-owned businesses. More specifically, many types of family-owned businesses exist as evident by specific …


A Study On Workforce Integration In An International Acquisition, Christopher Lussier Apr 2010

A Study On Workforce Integration In An International Acquisition, Christopher Lussier

Honors Projects in Management

International acquisitions are extremely difficult to maneuver and success is far from guaranteed. Navigating through financial statements is one thing, but trying to link together two or more geographically and culturally diverse workforces is an entirely another thing. This study analyzes fourteen employee interviews from four different companies involved in international acquisitions within the last ten years. It develops a comprehensive comparison of companies looking to partially integrate through hands-off management or fully integrate through synergistic collaboration of workforces. The analysis looks at the actions companies take once the decision is made to grow internationally through mergers and acquisitions in …


Including The Customer In Efficiency Analysis:Evidence Of A Hybrid Relational-Transactional Approach, Joseph Coughlan, Estelle Shale, Robert Dyson Mar 2010

Switching It Outsourcing Suppliers: Enhancing Transition Readiness, Siew Kien Sia, Wee Kiat Lim, Kanapaty Pelly Periasamy Mar 2010

Switching It Outsourcing Suppliers: Enhancing Transition Readiness, Siew Kien Sia, Wee Kiat Lim, Kanapaty Pelly Periasamy

CMP Research

As IT outsourcing continues to gather momentum and mature, the decision to change suppliers at the end of a contract, or even earlier, has become an inevitable reality for many. This article sheds light on the management challenges associated with transitioning from one outsourcing supplier to another. Based on the “painful” experience of a large public-sector organization that chose not to renew its contract with a supplier that had operated its online portal and call center for five years, we provide insights into what makes a client organization “transition-ready.” We then describe the actions an organization can take before, during, …


Index-Exciting Caviar: A New Empirical Time-Varying Risk Model, Dashan Huang, Baimin Yu, Zudi Lu, Sergio Focardi, Frank Fabozzi, Masao Fukushima Mar 2010

Index-Exciting Caviar: A New Empirical Time-Varying Risk Model, Dashan Huang, Baimin Yu, Zudi Lu, Sergio Focardi, Frank Fabozzi, Masao Fukushima

Research Collection Lee Kong Chian School Of Business

Instead of assuming the distribution of return series, Engle and Manganelli (2004) propose a new Value-at-Risk (VaR) modeling approach, Conditional Autoregressive Value-at-Risk (CAViaR), to directly compute the quantile of an individual asset's returns which performs better in many cases than those that invert a return distribution. In this paper we explore more flexible CAViaR models that allow VaR prediction to depend upon a richer information set involving returns on an index. Specifically, we formulate a time-varying CAViaR model whose parameters vary according to the evolution of the index. The empirical evidence reported in this paper suggests that our time-varying CAViaR …


A Psychological Perspective On Cultural Difference: Epistemological Heterogeneity And Individual Heterogeneity Across Cultures, Kamal Fatehi, Uday S. Tate Mar 2010

A Psychological Perspective On Cultural Difference: Epistemological Heterogeneity And Individual Heterogeneity Across Cultures, Kamal Fatehi, Uday S. Tate

Faculty and Research Publications

Most cross-cultural studies of management have been sociological type. Conventional view of cultures and sociological perspective has resulted in the assumption that within each culture members are homogeneous in their psychological make-up, logic, and perspective. Although researchers have reminded us that people vary on pivotal psychological dimensions, both on a between-country and within-country basis, these reminders were not heeded. Maruyama’s theories and research on epistemological heterogeneity, and individual heterogeneity across cultures, or as it is called, mindscape, were the exception. This paper elaborates on epistemological heterogeneity and individual heterogeneity across cultures. It suggests that researchers in international management could use …


An Investigation Of Value Updating Bidders In Simultaneous Online Art Auctions, Mayukh Dass, Lynne Seymour, Srinivas K. Reddy Feb 2010

An Investigation Of Value Updating Bidders In Simultaneous Online Art Auctions, Mayukh Dass, Lynne Seymour, Srinivas K. Reddy

Research Collection Lee Kong Chian School Of Business

Simultaneous online auctions, in which the auction of all items being sold starts at the same time and ends at the same time, are becoming popular especially in selling items such as collectables and art pieces. In this paper, we analyze the characteristics of bidders (Reactors) in simultaneous auctions who update their pre-auction value of an item in the presence of influencing bidders (Influencers). We represent an auction as a network of bidders where the nodes represent the bidders participating in the auction and the ties between them represent an Influencer?Reactor relationship. We further develop a random effects bilinear model …


Pension Plan Funding Effect On Shareholder Equity, Larisa Parchomovsky Feb 2010

Pension Plan Funding Effect On Shareholder Equity, Larisa Parchomovsky

Honors College Theses

A pension plan often tends to be one of the company’s biggest liabilities. Before 2008, pension plans were not directly included in the financial statements, but could only be found in the footnote disclosures. Such accounting convention essentially made pensions a type of off-balance sheet financing resulting in a misrepresentation of valuation ratios and earnings due to the exclusion of such a significant liability. The objective of this research is to determine whether the funded status of a pension plan will significantly affect a company’s shareholder equity. As part of this research, I analyzed 4 years (2001-2004) of financial statements …


The Impact Of Flexibility And Capacity Allocation On The Performance Of Primary Care Practices, Liang Wang Jan 2010

The Impact Of Flexibility And Capacity Allocation On The Performance Of Primary Care Practices, Liang Wang

Masters Theses 1911 - February 2014

The two important metrics for any primary care practice are: (1) Timely Access and (2) Patient-physician Continuity. Timely access focuses on the ability of a patient to get access to a physician as soon as possible. Patient-physician continuity refers to building a strong or permanent relationship between a patient and a specific physician by maximizing patient visits to that physician. In the past decade, a new paradigm called advanced access or open access has been adopted by practices nationwide to encourage physician to “do today’s work today.” However, most clinics still reserve pre-scheduled appointments for long lead-time appointments due to …


Team Identification, Trust, And Conflict: A Mediation Model, Guohong (Helen) Han, Peter D. Harms Jan 2010

Team Identification, Trust, And Conflict: A Mediation Model, Guohong (Helen) Han, Peter D. Harms

Leadership Institute: Faculty Publications

Design/methodology/approach — This is an empirical paper based on two field studies. In Study 1, 241 employees in a US Fortune 500 company distributed in various and mostly R&D teams were surveyed. In Study 2,205 employees in a health care organization in the Midwest were surveyed.
Findings — Team identification was related to lower levels of both task conflict and relationship conflict. This relationship, however, …


Emotional Intelligence And Transformational And Transactional Leadership: A Meta-Analysis, Peter D. Harms, Marcus Credé Jan 2010

Emotional Intelligence And Transformational And Transactional Leadership: A Meta-Analysis, Peter D. Harms, Marcus Credé

Leadership Institute: Faculty Publications

The purpose of this study is to evaluate claims that emotional intelligence is significantly related to transformational and other leadership behaviors. Results (based on 62 independent samples) indicated a validity estimate of .59 when ratings of both emotional intelligence and leadership behaviors were provided by the same source (self, subordinates, peers, or superiors). However, when ratings of the constructs were derived from different sources, the validity estimate was .12. Lower validity estimates were found for transactional and laissez-faire leadership behaviors. Separate analyses were performed for each measure of emotional intelligence. Trait measures of emotional intelligence tended to show higher validities …


Perceived Fairness Of Pay: The Importance Of Task Versus Maintenance Inputs In Japan, South Korea, And Hong Kong, Tae-Yeol Kim, Todd J. Weber, Kwok Leung, Yukiko Muramoto Jan 2010

Perceived Fairness Of Pay: The Importance Of Task Versus Maintenance Inputs In Japan, South Korea, And Hong Kong, Tae-Yeol Kim, Todd J. Weber, Kwok Leung, Yukiko Muramoto

Leadership Institute: Faculty Publications

This study compares East Asians’ evaluations of task and maintenance inputs in reward allocation decisions and examines the effects that inequity in various types of inputs and rewards have on fairness judgments. Based on a sample of 587 employees from various organizations in Hong Kong, Japan, and South Korea, we find that Hong Kong Chinese and South Korean employees are more likely to want their organizations and supervisors to emphasize maintenance inputs, while Japanese employees value task inputs in reward allocation. Results also show that there are significant country differences in fairness judgments associated with various types of inputs. For …


Spreadsheets Grow Up: Three Spreadsheet Engineering Methodologies For Large Financial Planning Models, Thomas A. Grossman Jr., O Ozluk Jan 2010

Spreadsheets Grow Up: Three Spreadsheet Engineering Methodologies For Large Financial Planning Models, Thomas A. Grossman Jr., O Ozluk

Business Analytics and Information Systems

Many large financial planning models are written in a spreadsheet programming language (usually Microsoft Excel) and deployed as a spreadsheet application. Three groups, FAST Alliance, Operis Group, and BPM Analytics (under the name “Spreadsheet Standards Review Board”) have independently promulgated standardized processes for efficiently building such models. These spreadsheet engineering methodologies provide detailed guidance on design, construction process, and quality control. We summarize and compare these methodologies. They share many design practices, and standardized, mechanistic procedures to construct spreadsheets. We learned that a written book or standards document is by itself insufficient to understand a methodology. These methodologies represent a …


Trusts Versus Corporations: An Empirical Analysis Of Competing Organizational Forms, A. Joseph Warburton Jan 2010

Trusts Versus Corporations: An Empirical Analysis Of Competing Organizational Forms, A. Joseph Warburton

College of Law - Faculty Scholarship

This paper studies the effects of organizational form on managerial behavior and firm performance, from an empirical perspective. Managers of trusts are subject to stricter fiduciary responsibilities than managers of corporations. This paper examines the ramifications empirically, by exploiting data generated by a change in British regulations in the 1990s that allowed mutual funds to organize as either a trust or a corporation. I find evidence that trust law is effective in curtailing opportunistic behavior, as trust managers charge significantly lower fees than their observationally equivalent corporate counterparts. Trust managers also incur lower risk. However, evidence suggests that trust managers …


The Application Of Little's Law To Enrollment Management: Improving Student Persistence In Part-Time Degree Programs, Ellen M. Walk, Lewis A. Litteral Jan 2010

The Application Of Little's Law To Enrollment Management: Improving Student Persistence In Part-Time Degree Programs, Ellen M. Walk, Lewis A. Litteral

Management Faculty Publications

Little’s Law is applied to enrollment management in part-time degree programs. Using institutional data by program, on number of graduates per year, as well as number of credits taken and number of active students per semester, the calculated average time to graduation is compared to the average flow time predicted by Little’s Law. Despite significant variability among students who enter with varying transfer credits and take varying credits per semester, Little’s Law provides a simple model for measuring program growth trends, student productivity, and persistence to graduation. Implications for marketing, admissions, advising, course scheduling, and curriculum design are discussed.
