Literary Destination Familiarity And Inbound Tourism: Evidence From Chinese Mainland, Guodong Ju, Jiankun Liu, Guangye He, Xinyi Zhang, Fei Yan

Journal of Social Computing

Destination familiarity is an important non-economic determinant of tourists’ destination choice that has not been adequately studied. This study posits a literary dimension to the concept of destination familiarity—that is, the extent to which tourists have gained familiarity with a given destination through literature—and seeks to investigate the impact of this form of familiarity on inbound tourism to Chinese mainland. Employing the English fiction dataset of the Google Books corpus, the New York Times annotated corpus, and the Time magazine corpus, we construct two types of destination familiarity based on literary texts: affection-based destination familiarity and knowledge-based destination ...

Journal of Social Computing

Researchers have attempted to measure the success of crowdfunding campaigns using a variety of determinants, such as the descriptions of the crowdfunding campaigns, the amount of funding goals, and crowdfunding project characteristics. Although many successful determinants have been reported in the literature, it remains unclear whether the cover photo and the text in the title and description could be combined in a fusion classifier to better predict the crowdfunding campaign’s success. In this work, we focus on the performance of the crowdfunding campaigns on GoFundMe across a wide variety of funding categories. We analyze the attributes available at the ...


An Operator-Based Approach For Modeling Influence Diffusion In Complex Social Networks, Chenting Jiang, Anthony D’Arienzo, Weihua Li, Shiqing Wu, Quan Bai Mar 2022

An Operator-Based Approach For Modeling Influence Diffusion In Complex Social Networks, Chenting Jiang, Anthony D’Arienzo, Weihua Li, Shiqing Wu, Quan Bai

Journal of Social Computing

Social media have dramatically changed the mode of information dissemination. Various models and algorithms have been developed to model information diffusion and address the influence maximization problem in complex social networks. However, it appears difficult for state-of-the-art models to interpret complex and reversible real interactive networks. In this paper, we propose a novel influence diffusion model, i.e., the Operator-Based Model (OBM), by leveraging the advantages offered from the heat diffusion based model and the agent-based model. The OBM improves the performance of simulated dissemination by considering the complex user context in the operator of the heat diffusion based model ...

Uncovering The Online Social Structure Surrounding Covid-19, Philip D. Waggoner, Robert Y. Shapiro, Samuel Frederick, Ming Gong

Journal of Social Computing

How do people talk about COVID-19 online? To address this question, we offer an unsupervised framework that allows us to examine Twitter framings of the pandemic. Our approach employs a network-based exploration of social media data to identify, categorize, and understand communication patterns about the novel coronavirus on Twitter. The simplest structure that emerges from our analysis is the distinction between the internal/personal, external/global, and generic threat framings of the pandemic. This structure replicates in different Twitter samples and is validated using the variation of information measure, reflecting the significance and stability of our findings. Such an exploratory ...

Exploring Youths’ Decision To Participate In Stem Afterschool Programs, Brooke M. Stafford, Virginia L. J. Bolshakova

Indiana STEM Education Conference

STEM afterschool programs offer a range of academic, social, and emotional outcomes to support positive youth development. In particular, STEM afterschool programs have been shown to increase student self-efficacy and interest in pursuing STEM careers (Chan et al., 2020; Dabney et al., 2012). Youth must first choose to attend the STEM afterschool programs to gain the many benefits offered. However, participation in such programs decreases as youth get older and encounter additional competing interests (i.e., home responsibilities, jobs, etc.). To get youth to attend, STEM afterschool programs must meet the needs of youth by leveraging resources, activities, and relationships ...

Deepfakes, Shallowfakes, And The Need For A Private Right Of Action, Eric Kocsis

Dickinson Law Review

For nearly as long as there have been photographs and videos, people have been editing and manipulating them to make them appear to be something they are not. Usually edited or manipulated photographs are relatively easy to detect, but those days are numbered. Technology has no morality; as it advances, so do the ways it can be misused. The lack of morality is no clearer than with deepfake technology.

People create deepfakes by inputting data sets, most often pictures or videos into a computer. A series of neural networks attempt to mimic the original data set until they are nearly ...

Uas For Public Safety: Active Threat Recognition, Joseph Cerreta, Tray Denney, Scott S. Burgess, Anthony Galante, David Thirtyacre, Gloria A. Wilson, Patrick Sherman

International Journal of Aviation, Aeronautics, and Aerospace

The Center for Homeland Defense and Security identified an increase of active threat events, such as mass shootings, annually since 1999. Literature suggests that 90% of shootings were over before law enforcement arrived at the scene and the first responder response was limited to “surround and contain” until Special Weapons and Tactics Teams (SWAT) arrived on the scene. Using Unmanned Aircraft Systems (UAS) to detect which individual was the threat and type of weapon used can provide useful information to increase the speed of the response for first-on-scene rather than waiting for SWAT if the type of weapon was known ...
