Safety Evaluation Of Amusement Rides Using Accumulated Accident Data: Accident Data Framework, Kathryn Woodcock Apr 2022

Safety Evaluation Of Amusement Rides Using Accumulated Accident Data: Accident Data Framework, Kathryn Woodcock

Journal of Themed Experience and Attractions Studies

Amusement rides and devices are a popular form of recreation and important component of the tourism industry. Injury-producing accidents are rare, and the viability of the industry relies on perceived safety of the activity. Some existing metrics use accumulated accident reports. Several metrics tabulate the number of injuries, but none collect enough information about the context of accidents to analyse the accumulated data to deduce patterns. This paper describes an Accident Data Framework for a minimal set of variables from reports of amusement device accident, and the structure for a useful narrative to aid reporters and recorders to avoid introducing …

Brighter But Not Clearer: Entertainment-Dependent Destinations Dealing With Long Covid, Louis-Etienne Dubois, Frederic Dimanche

Journal of Themed Experience and Attractions Studies

At the onset of the COVID-19 pandemic, we explored a range of very different possible outcomes for destinations that rely heavily on their entertainment sector (Dubois & Dimanche, 2021). Several months later, this article seeks to revisit those outcomes, while also highlighting the ongoing recovery efforts and evolving strategies of entertainment-dependent destinations (EDDs). To do so, we reconnected with the panel of respondents from various destinations (i.e., Las Vegas, Nashville, New Orleans etc.) to take stock of both new challenges and opportunities, as well as emerging factors impacting their respective markets. Our results show that while EDDs are facing a …


Theme Parks, Staycation Practices, And Covid-19: Opportunities And Uncertainties, Salvador Anton Clavé Apr 2022

Theme Parks, Staycation Practices, And Covid-19: Opportunities And Uncertainties, Salvador Anton Clavé

Journal of Themed Experience and Attractions Studies

The effects of COVID-19 on the market transformation of the theme park industry has been significant in the short term because of travel restrictions. Challenges, impacts, responses, and strategies might vary from one region to another and even from one theme park to another. However, it can be assumed that domestic travel will continue to have an effect on the theme park industry during the months to come and likely beyond the pandemic. In this context, the “staycation” is becoming a booming trend in the leisure, entertainment, and tourism industry, creating new, current, and future unexpected economic winners and losers. …


Disney During Covid-19: The Tourist And The Actor’S Nightmare, Jennifer A. Kokai, Tom Robson Apr 2022

Disney During Covid-19: The Tourist And The Actor’S Nightmare, Jennifer A. Kokai, Tom Robson

Journal of Themed Experience and Attractions Studies

In this essay, we argue that the experience of being at Disney theme parks in COVID times was a waking version of what is sometimes called “The Actor’s Nightmare.” Due to safety regulations, theme parks either dropped live entertainment that structures the day as a show with a clear beginning and end (e.g. park-opening rope drop performances, and the fireworks), attempted to include references to COVID in live entertainment (like in

the Frozen Ever After singalong, which added some COVID jokes), or to ignore it (like the Festival of the Lion King). In any case, due to these measures the …


The “Politics Of Inclusion/Exclusion” In Times Of The Pandemic, Florian Freitag Apr 2022

The “Politics Of Inclusion/Exclusion” In Times Of The Pandemic, Florian Freitag

Journal of Themed Experience and Attractions Studies

As commercial enterprises that depend on attracting a maximum number of visitors in order to be economically successful, theme parks have generally been careful to avoid unpleasant, sensitive, or controversial themes (or aspects of a theme) that might offend or alienate potential customers. Due to official regulations concerning e.g. the wearing of masks in waiting lines and during rides, however, the pandemic cannot simply be “excluded” from the parks and remains constantly visually present, thus seriously undermining the companies’ efforts to keep the park grounds rigidly separated from the rest of the world. Particular operational decisions by some theme park …

Are European Theme Parks Likely To Suffer From Long Covid?, Pieter Cornelis Apr 2022

Are European Theme Parks Likely To Suffer From Long Covid?, Pieter Cornelis

Journal of Themed Experience and Attractions Studies

COVID-19 has had a major impact on the theme park industry. Visits to European parks were significantly lower in 2020 than the year before. This article discusses the short-term and long-term economic consequences of the pandemic for the theme park industry. Attitudinal loyalty, inertia effects of guest satisfaction on repeat visits, (deferred) reinvestments, and the difference between theme and amusement parks will be considered. To compensate for losses in 2020, many parks increased their visitor numbers in the 2021 season to the maximum permitted capacity, especially in the summer months. As a result, analysis of waiting times at 22 investigated …


Introduction: Theme Parks And Covid-19, Salvador Anton Clavé, Florian Freitag Apr 2022

Introduction: Theme Parks And Covid-19, Salvador Anton Clavé, Florian Freitag

Journal of Themed Experience and Attractions Studies

In the tourism industry, “crises” have been conceptualized as local and temporary phenomena, interval states that may require imminent action, but that can eventually be overcome, with business simply resuming. At the moment of writing, however, it is not at all clear when or if the theme park sector can simply return to a pre-pandemic state of affairs. Even if tourism may once again attain pre-COVID numbers, it may well be through entirely new and different forms. The essays collected here provide scholarly and professional snapshots of the current (winter 2021/2022) state of the theme park industry, with special attention …

Complex Quantum Contagion: A Quantum-Like Approach For The Analysis Of Co-Evolutionary Dynamics Of Social Contagion, Ece Mutlu Jan 2022

Complex Quantum Contagion: A Quantum-Like Approach For The Analysis Of Co-Evolutionary Dynamics Of Social Contagion, Ece Mutlu

Electronic Theses and Dissertations, 2020-

Modeling the dynamics of social contagion processes has recently attracted a substantial amount of interest from researchers due to its wide applicability in network science, multi-agent systems, information science, and marketing. Unlike in biological spreading, the existence of a reinforcement effect in social contagion necessitates considering the complexity of individuals in the systems. Although many studies acknowledged the heterogeneity of the individuals in their adoption of information (or behavior), there are no studies that take into account the individuals' uncertainty during their decision-making despite its theoretical and experimental evidence in behavioral economics, decision science, cognitive science, or multi-agent systems. This …


A Contingent Approach To Studying Technical Programs In The Public Aerospace Industry, Laura Segarra Jan 2022

A Contingent Approach To Studying Technical Programs In The Public Aerospace Industry, Laura Segarra

Electronic Theses and Dissertations, 2020-

Bibliometric evaluation of the literature indicates that a unified theory of program management does not yet exist. The vastly different definitions and implementations of programs across organizations and industries indicate that program management as an organizational concept is not well understood. As researchers have tried to make sense of various perspectives and definitions, it becomes clear that different kinds of programs exist, and further attention to their context is needed. While relationships between structural and environmental variables have been extensively researched in organizational studies, studies in program management are scant, lack incorporation of environmental variables relevant to programs and projects, …

Investigating The Effects Of Negative Influence Gradients And Emotion Contagion On The Information Processing Capacity Of Social Media Users: Information Diffusion Modeling Approach, Nisha Baral

Electronic Theses and Dissertations, 2020-

With the growing use of Online social media (OSM), users are observing a substantial amount of information in their social feeds. Moreover, people often use multiple OSM platforms because of each platform's unique features. Because of the huge volume of information present in social feeds, it restricts a user's ability to process the relevant information since the most important information may be overwhelmed by unimportant information. For information to diffuse in OSM, the receiver's attention is the most important condition. Cognition plays an important role in determining a user's attention/responsiveness. If OSM users receive the information above their cognition limits …


Not All Influence Is Born Equal: On The Effects Of Various Types Of Behavioral Influence Relationships On Social Media, Chathurani Senevirathna Jan 2022

Not All Influence Is Born Equal: On The Effects Of Various Types Of Behavioral Influence Relationships On Social Media, Chathurani Senevirathna

Electronic Theses and Dissertations, 2020-

Typically, online social influence is analyzed using a single metric approach. However, social influence is not monolithic; different users exercise different influences in different ways, and influence is correlated with the user and content-specific attributes. One such attribute could be whether the action is an initiation of a new post, a contribution to a post, or a sharing of an existing post. Thus, this dissertation uses this platform-independent action classification and models the influence as multiple entities and examines social networks through the perspective of behavioral influence propagation. Two empirical studies are present in this dissertation. The first study presents …

Development Of A Multivariate Poisson Hidden Markov Model For Application In Educational Data Mining, Shahab Boumi

Electronic Theses and Dissertations, 2020-

Managers and policymakers in higher education institutions try to improve graduation rates and decrease halt rates. To achieve this goal, it is important to understand academic and demographic factors that correlate with academic performance. Many studies in the field of education analytics have identified student grade point averages (GPA) as an important indicator and predictor of final academic outcomes (graduating or halting their studies). While semester-to-semester fluctuations in GPA are considered normal, significant changes in academic performance may warrant more thorough investigation and consideration, particularly with regard to final academic outcomes. However, it is challenging to represent complex academic trajectories …

Humans In Algorithms, Algorithms In Humans: Understanding Cooperation And Creating Social Ai With Causal Generative Models, Lux Miranda

Electronic Theses and Dissertations, 2020-

Cooperation is the hallmark human trait which has allowed us to congregate into the vast, continent-sprawling societies we live in today. Yet, the precise social, environmental, and cognitive mechanisms which enable this cooperation are not fully understood. Toward this, lucrative insights have been borne through the use of formal computational models of socio-cognitive phenomena: In simulating our own cooperative behavior, we can better deduce the exact factors which cause it. The combined knowledge of these factors and ability to computationally simulate them allows us to further two goals: First, it empowers us with the knowledge of how to modify our …
