Monitoring Airport Service Quality: A Complementary Approach To Measure Perceived Service Quality Using Online Reviews, Kiljae Lee, Chunyan Yu

Chunyan Yu

Based on 42,063 airport reviews collected from Google Maps, we conducted a sentiment analysis and a topic modeling. We showed that the sentiment scores computed from textual reviews are good estimates of their paired star-ratings (r=0.63, p<0.01). Next, using the LDA (Latent Dirichlet Allocation), we extracted latent topics from the textual reviews and compared them with the standard categories utilized in the Airport Service Quality survey (ASQ). The topics extracted from reviews correspond well with the categories used in ASQ. We, in turn, compared the online ratings with the ratings annually updated by ASQ. While online reviews discuss almost identical topics with those of ASQ, the correlation between the ratings from two was weak (r=0.2). We suggest that the text mining approach using online reviews not only provides an inexpensive, dynamic, and locally customizable means of monitoring airport quality but also complements the standard survey by offering an alternative metric. ><0.01).

A Taxonomy Framework For Maritime Cybersecurity: A Demonstration Using The Automatic Identification System, G. C. Kessler, J. P. Craiger, J. C. Haass

J. Philip Craiger, Ph.D.

The maritime transportation system is increasingly a target of cyber attacks. This paper describes a taxonomy that supports the creation of adversarial cyber models, risk mitigation, and resiliency plans as applied to the maritime industry, using the Automatic Identification System as a specific illustration of the approach. This method has already been applied to the aviation sector; retooling it for a maritime example demonstrates its broad applicability to the transportation sector, in general.

Addressing The Supportive Transportation Challenges Of Community-Residing Older Adults, Nina M. Silverstein, Kristina M. Turk, Laura Adams, Holly Belanger, Linnea Burke, Stephen Jones, Lauren Lee, David Lopez, Keith Sherman, Lee Paradis, Erin O’Neill, Alycia Rao, Rachael Solano

Nina Silverstein

The ability to get to where you want to go, when you want to go there is a key factor for aging-in-place in our communities. It is often taken for granted until that ability is compromised. The informal network of family and friends, if it exists, is not likely to be a sustainable transportation alternative for persons with cognitive impairment or for older adults with limitations that may not fit eligibility criteria for senior transportation services, where they exist. The purpose of this study was to investigate the potential of communities to address the specialized supportive mobility needs of community-residing …

A General Framework For Price Regulation Of Airports, Sock Yong Phang

PHANG Sock Yong

Price cap regulation (PCR) was first implemented for privatized utilities in the UK in the 1980s. It has since been adopted by numerous countries as a regulatory regime in several sectors. This paper focuses on the development of different forms of price regulation of airports of which PCR is one variant. In countries where airport privatization is still in the early stages, the spectrum of airports and varied nature of regulatory regimes can be confusing and the lack of a general framework can itself become an obstacle to privatization. This paper proposes a general framework comprising decisions to be made …

The Organisational Climate Of Sustainability: A Survey, Anke Arnaud, Janet K. Tinoco, Dawna L. Rhoades

Dr. Anke Arnaud

This study describes three dimensions of the climate of sustainability and the development of a survey for assessing these dimensions. The authors report the results of two studies conducted to measure the climate of sustainability dimensions of sensitivity to sustainability (six items), motivation for sustainability (six items), and responsibility for sustainability (five items). Results support that the climate of sustainability is a reliable instrument and demonstrate the convergent and discriminant validity of each survey dimension. Furthermore, results show the criterion-related validity of the climate of sustainability with respect to innovation strategy and employee attitudes including satisfaction and turnover intentions. Implications …

Managing People And Technology: The Challenges In Csr And Energy Efficient Shipping, Momoko Kitada, Aykut Ölçer

Aykut Ölçer

This paper addresses the challenges of managers in the shipping industry to implement energy efficient measures in ship operations and their roles of managing both people and technology under the fulfilment of their corporate social responsibility (CSR). An increasing pressure on shipping companies to concern about marine environment, including energy efficiency, has led managers to consider CSR as their ethical business practices. It is an accepted norm that shipping is generally the most environmentally friendly mode of transport in terms of CO2 produced per ton nautical mile. Despite an extensive amount of research available to improve energy efficiency in shipping, …

Introducing The Concept Of Resilience Into Maritime Safety, Jens-Uwe Schröder-Hinrichs Phd, Gesa Praetorius, Armando Graziano, Aditi Kataria, Michael Baldauf

Michael Baldauf

The maritime industry is still characterized by prescriptive standards and reactive approaches in relation to safety and risk management to a large extent. For a very long time, responses to maritime accidents have been in terms of automation, regulation and training. While this as such is not wrong, it does not offer the full potential that concepts of resilience seem to suggest. The typical question that is predominately asked is still why things go wrong when accidents occur and search for causes and explanations is undertaken. An evaluation of the safety level achieved system and a focus on system components …

Increased Awareness For Maritime Human Factors Through E-Learning In Crew-Centered Design, Gesa Praetorius, Aditi Kataria, Erik Styhr Petersen, Jens-Uwe Schröder-Hinrichs, Michael Baldauf, Nina Kähler

Gesa Praetorius

In the past two decades, the need to address human factors in shipping through integration of ergonomics in the design of ships and shipboard equipment has increased significantly as a result of the technological development of modern ships. The International Maritime Organization (IMO), the United Nations’ specialized organizationfor ship safety issues, has adopted a vision to address human factors as a key element for the improvement of maritime safety, and in that context acknowledges the human element as complex and multi-dimensional. IMO’s standards focus on the avoidance of human and organization error. But in spite of this, and despite the …

Modeling Of On-Line Traffic Control And Management Network For Operational And Communication Performance Evaluation, Yan Zhou

Yan Zhou 周彦文档

Communication systems are the backbone of every effective and reliable traffic control and management application. While traditional fiber optics and telephone communications have long been used in managing and controlling highway traffic, wireless communication technology shows great promise as an alternative solution in traffic management applications due to their suitability for deployment in rural areas, and their flexibility and cost-effectiveness for system expansion. However, the detailed characteristics of various wireless communication technologies and real performance in the field have not been systematically studied. To augment this existing knowledge so that traffic professionals may better utilize these technologies to improve traffic …

A Simplified Method For Analyzing Factors Contributing To Motorcyclists’ Fatal Injuries In Ohio, Deogratias Eustace, Vamsi Krishna Indupuru

Deogratias Eustace

The aim of this paper was to analyze traffic crash data by using a simplified method in determining significant factors that increase the risk of a motorcyclist being fatally injured once involved in a motorcycle crash in Ohio. The concept of overrepresentation, which is similar to relative risk, was used in identifying significant variables associated with the elevated risk of a motorcycle crash resulting into a fatality. The overrepresentation factor (ORF) was calculated for each variable of interest. The ORF offers a simple but powerful procedure of determining whether a certain factor significantly occurs more or less frequently in one …

The New Panama Canal In A Global Context, Herman L. Boschken

Herman L. Boschken

Without the "container revolution" (1970-present) and its redesign of seaport and maritime-trade infrastructures, globalization as we know it would not exist. With the recent enlargements of the Panama and Suez Canals, many new implications for U.S. economic trade are unfolding. This presentation at the Commonwealth Club of California, outlines recent changes in world trade and infrastructure development, and poses five factors that will likely determine winners and losers in the unfolding developments of this highly competitive world trade-route system.

Global Trade Impacts: Addressing The Health, Social And Environmental Consequences Of Moving International Freight Through Our Communities, Martha Matsuoka, Andrea Hricko, Robert Gottlieb, Juan Delara

Martha Matsuoka

As ports and goods movement activity expands throughout the United States, a major challenge is how to make the adverse impacts of freight transportation a more central part of economic development, policy and planning discussions and transportation decision making. In 2009, faculty and staff from the Urban & Environmental Policy Institute of Occidental College and from the environmental health sciences and regional equity programs of the University of Southern California (USC) began a study of this evolving global trade and freight transportation system, focusing on areas in the United States where the system is expanding and where community, labor and …

Critical Assessment Of The Literature Regarding The Public Costs Of Roadway Damage Due To Fracking, Brent Ritzel

Brent Ritzel

Many government bodies have raised concerns regarding preservation of existing public roadway systems from infrastructure damage, and roadway degradation in particular, due to the impact of fracking-related truck traffic on roads that are simply not designed for that level and intensity of usage. This significant heavy usage imposes both immediate and long-term cost burdens on taxpayers, and can create unfunded liabilities for the wide range of levels of government (jurisdictions) responsible for maintaining the roadways (from township to federal). This acceleration in roadway consumption has manifested a financial need that is not easily funded by traditional fee mechanisms.
