Analysis Of Low-Cost Carriers In The Post-Soviet States, Tamilla Curtis, Dawna L. Rhoades Jun 2013

Analysis Of Low-Cost Carriers In The Post-Soviet States, Tamilla Curtis, Dawna L. Rhoades

Publications

The research paper provides an overview of low-cost carrier (LCC) development in the post- Soviet states with the analysis of the largest aviation market in Russia. The LCC model seeks to achieve a competitive advantage through the reduction of operating costs below the traditional airline model. Since the post-Soviet states are emerging economies, airlines face a high level of uncertainty and experience a number of unique problems. While the global community enjoys the benefits offered by LCCs, the question remains why this model has not been successful in the 15 newly formed countries, with the exception of the Hungarian low-cost …

Ancillary Revenue And Price Fairness: An Exploratory Study Pre & Post Flight, Blaise P. Waguespack, Tamilla Curtis

Publications

The growing impact of Ancillary Revenue on consumer choice and shopping behavior continues to be a highly debated issue. In the US, the Department of Transportation (DOT) has stepped into the debate and is investigating the possibility of new rules on how airlines must report and display such ancillary offerings. While the DOT collects data, reports on the amount of ancillary revenue earned by the airlines continue to rise. Examining past research on price fairness from the marketing literature and the impact of revenue management on price fairness from the aviation literature, this article joins new research appearing on the …

Market Analysis For Small And Mid-Size Commercial Turboprop Aircraft, Vitaly S. Guzhva, Tamilla Curtis, Vladislav Borodulin Jun 2013

Market Analysis For Small And Mid-Size Commercial Turboprop Aircraft, Vitaly S. Guzhva, Tamilla Curtis, Vladislav Borodulin

Publications

Recent fuel price volatility and growing concerns about the efficiency of regional jets have led to a revival of large turboprop aircraft as efficient passenger carriers on short-haul regional routes. However, the overall market for smaller turboprops is much less defined as it is characterized by a plethora of small commuter and niche operators in addition to regional carriers. Since most small and mid-size turboprop manufacturers have gone bankrupt or discontinued production due to some other reasons, current operators of this aircraft class are left with aging fleets that would need to be replaced by 2020-2030. This paper assesses the …

The Novelty And Nostalgia Effects Of A New Major League Baseball Stadium As Measured By Its Impact On Attendance, The Corresponding Costs Of Attending, And Ticket Revenue, Sam Fullerton, Carol Bruneau Jun 2013

The Novelty And Nostalgia Effects Of A New Major League Baseball Stadium As Measured By Its Impact On Attendance, The Corresponding Costs Of Attending, And Ticket Revenue, Sam Fullerton, Carol Bruneau

Journal of Applied Marketing Theory

Using secondary data, the novelty effect of the opening of 15 new Major League Baseball stadiums was determined. Using a seven-year period looking both before and after each stadium’s inaugural season, a meaningful novelty effect was documented. There were significant increases in attendance and the average ticket price for each of the 15 teams under scrutiny. As a consequence, there was a significant increase in the revenue generated through ticket sales. While the anticipated spike was in evidence for the year a new stadium opened, meaningful increases were also documented for the years subsequent to the opening of the new …

Passion Transfer In Sports Advertising: Sports Passion And Attitude Toward Advertising, Brandon Brown, Larry Degaris Jun 2013

Passion Transfer In Sports Advertising: Sports Passion And Attitude Toward Advertising, Brandon Brown, Larry Degaris

Journal of Applied Marketing Theory

In order to retain advertising clients, media companies are in search of viable strategies that can justify the high costs of advertising fees within the sports setting. In acknowledging the significance of advertising during sport programs, the current study seeks to investigate the value of sports advertising by introducing the concept of ‘passion transfer’ (i.e., the transference of high likability levels of sport programs to the sport programs’ advertisements). We examine this concept by analyzing the relationship between viewer passion towards programming and advertising effectiveness. In doing so, the study also lends support to the notion of incorporating emotional measures …

Gift Cards And Gift Giving, Melek Meral Anitsal, Ismet Anitsal, Amanda Brown

Journal of Applied Marketing Theory

Gift cards are frequently located at premium points inside the retail space where stores sell not only their own cards but also other retailers’ cards for almost every occasion. Media encouraged practitioners to promote these cards. However, this emerging phenomenon of consumers’ preference of gift cards has not been explored thoroughly yet. The objective of the current study is to understand consumer reactions to gift cards in terms of their impact in gift giving and gift receiving relationships. Specifically, this qualitative research seeks to investigate the following research objectives: (1) How gift givers and receivers perceive gift cards; (2) What …

An Integrated Decision Support Framework For Assessing Food Supply Chain Risk Management Processes: A Food Retail Case Study, Amr Arisha, John Crowe Jun 2013

An Integrated Decision Support Framework For Assessing Food Supply Chain Risk Management Processes: A Food Retail Case Study, Amr Arisha, John Crowe

Conference papers

Global confidence and reliability in Irish food supply chains are essential elements to overall competiveness and future growth. The complex nature of food supply chains make them vulnerable to many sources of risk, both internal and external. Integrating the SCOR11 model with system dynamics and discrete-event simulation modelling is effective decision support integration, reducing the risks decision makers have to manage daily. At GRD, using the integrated framework to assess the risks associated with lean initiatives helped management in understanding both the risk scenario, likelihood and impact factor of their decisions on operations performance measures.

Two Decades Of Rpl/Apel In Ireland: Practitioner Views, Deirdre Goggin

Level 3

My initial involvement was as an RPL assessor of an application for a marketing subject I was delivering through the Continuing Education Department. At the time RPL was not as developed as it is now within CIT. I received the required paper work and sat down with Phil O’Leary, CIT’s RPL Officer, who familiarised me with the process. In later years I moved from the private sector into the RPL office of CIT. I assisted staff and students in the RPL process, in preparing and assessing material. In conjunction with Phil O’Leary we developed an updated student handbook for circulation …

Shackling Short Sellers: The 2008 Shorting Ban, Ekkehart Boehmer, Charles M. Jones, Xiaoyan Zhang Jun 2013

Shackling Short Sellers: The 2008 Shorting Ban, Ekkehart Boehmer, Charles M. Jones, Xiaoyan Zhang

Research Collection Lee Kong Chian School Of Business

In September 2008, the U.S. Securities and Exchange Commission (SEC) temporarily banned most short sales in nearly 1,000 financial stocks. We examine the ban's effect on market quality, shorting activity, the aggressiveness of short sellers, and stock prices. The ban's effects are concentrated in larger stocks; there is little effect on firms in the lower half of the size distribution. Although shorting activity drops by about 77% in large-cap stocks, stock prices appear unaffected by the ban. All but the smallest quartile of firms subject to the ban suffer a severe degradation in market quality.

Collaborative Benefits And Coordination Costs: Learning And Capability Development In Science, M. Onal Vural, Linus Dahlander, Gerard George

Research Collection Lee Kong Chian School Of Business

We examine the effects of team structure and experience on the impact of inventions produced by scientific teams. Whereas multidisciplinary, collaborative teams have become the norm in scientific production, there are coordination costs commensurate with managing such teams. We use patent citation analysis to examine the effect of prior collaboration and patenting experience on invention impact of 282 patents granted in human embryonic stem cell (hESC) research from 1998 to 2010. Our results reveal that team experience outside the domain may be detrimental to project performance in a setting where the underlying knowledge changes. In stem cell science, we show …

Compliant Sinners, Obstinate Saints: How Power And Self-Focus Determine The Effectiveness Of Social Influences In Ethical Decision Making, Marko Pitesa, Stefan Thau

Research Collection Lee Kong Chian School Of Business

In this research, we examine when and why organizational environments influence how employees respond to moral issues. Past research has proposed that social influences in organizations affect employees' ethical decision making, but has not explained when and why some individuals are affected by an organizational environment and some disregard it. To address this problem, we drew on research on power to propose that power makes people more self-focused, which, in turn, makes them more likely to act upon their preferences and ignore (un)ethical social influences. Using both experimental and field methods, we tested our model across the three main paradigms …

Adaptive Credit Scoring With Analytic Hierarchy Process, Kwang Yong Koh, Murphy Choy, Michelle L. F. Cheong

Research Collection School Of Computing and Information Systems

Credit risk assessment for consumers has been a cornerstone of risk management in financial institutions and constitutes a component of the three pillars of Basel II. Traditionally, the concept of 5 ‘C’s was widely adopted by financial institutions as the key basis for credit risk assessment for loan applications by prospective borrowers. With the evolution of the credit risk management practices, more quantitative methods such as credit scorecards have been developed, which is implemented through the use of logistic regression, decision trees and neural networks. However, such approaches proved to be inadequate with the validity and effectiveness of the approaches …

Cameo: A Middleware For Mobile Advertisement Delivery, Azeem J. Khan, Kasthuri Jayarajah, Dongsu Han, Archan Misra, Rajesh Krishna Balan, Srinivasan Seshan

Research Collection School Of Computing and Information Systems

Advertisements are the de-facto currency of the Internet with many popular applications (e.g. Angry Birds) and online services (e.g., YouTube) relying on advertisement generated revenue. However, the current economic models and mechanisms for mobile advertising are fundamentally not sustainable and far from ideal. In particular, as we show, applications which use mobile advertising are capable of using significant amounts of a mobile users' critical resources without being controlled or held accountable. This paper seeks to redress this situation by enabling advertisement supported applications to become significantly more "user-friendly". To this end, we present the design and implementation of CAMEO, a …

Enforcing Secure And Privacy-Preserving Information Brokering In Distributed Information Sharing, Fengjun Li, Bo Luo, Peng Liu, Dongwon Lee, Chao-Hsien Chu Jun 2013

Enforcing Secure And Privacy-Preserving Information Brokering In Distributed Information Sharing, Fengjun Li, Bo Luo, Peng Liu, Dongwon Lee, Chao-Hsien Chu

Research Collection School Of Computing and Information Systems

Today’s organizations raise an increasing need for information sharing via on-demand access. Information brokering systems (IBSs) have been proposed to connect large-scale loosely federated data sources via a brokering overlay, in which the brokers make routing decisions to direct client queries to the requested data servers. Many existing IBSs assume that brokers are trusted and thus only adopt server-side access control for data confidentiality. However, privacy of data location and data consumer can still be inferred from metadata (such as query and access control rules) exchanged within the IBS, but little attention has been put on its protection. In this …
