Advocacy On Facebook: A Content Analysis Of How Small Los Angeles- Based Npos Use Social Media To Engage Audiences, Wen Chen Denq

Dissertations

This dissertation examined the Facebook activities of seven small nonprofits in Los Angeles to understand their social media use and audience responses. Prior research has distinguished three broader engagement strategies used by Nonprofit Organizations (NPOs), including information provision (awareness-raising), action-related messaging (mobilizing), and community-building efforts (organizing). These strategies can play essential roles in drawing in audiences, but also in moving individual supporters toward greater levels of engagement by increasing donations or becoming more engaged champions for the cause. A qualitative and quantitative analysis of organizational Facebook messages and audience responses was conducted over 3 months. The NPOs included in this …

Applied Microeconomics And Business Intelligence In The Digital Age, Thomas J. Weinandy

Dissertations

The Digital Age is defined by advances in big data, low-cost computing, and modern analytical methods. In three chapters, I apply microeconomic thought to the influence these digital technologies have on business and consumer decision-making.

Chapter One considers how Transportation Network Companies (TNCs) like Uber and Lyft impact the relationship between the quantity of car service trips and fuel prices. I find that a single day 1% increase in fuel prices is associated with a 0.367 to 0.486% decrease in the number of TNC trips and a 0.033 to 0.088% increase in the number of taxi trips, even though the …

Early Detection Of Fake News On Social Media, Yang Liu

Dissertations

The ever-increasing popularity and convenience of social media enable the rapid widespread of fake news, which can cause a series of negative impacts both on individuals and society. Early detection of fake news is essential to minimize its social harm. Existing machine learning approaches are incapable of detecting a fake news story soon after it starts to spread, because they require certain amounts of data to reach decent effectiveness which take time to accumulate. To solve this problem, this research first analyzes and finds that, on social media, the user characteristics of fake news spreaders distribute significantly differently from those …

Detecting User Demographics In Twitter To Inform Health Trends In Social Media, Christopher R. Markson

Dissertations

The widespread and popular use of social media and social networking applications offer a promising opportunity for gaining knowledge and insights regarding population health conditions thanks to the diversity and abundance of online user-generated information (UGHI) relating to healthcare and well-being. However, users on social media and social networking sites often do not supply their complete demographic information, which greatly undermines the value of the aforementioned information for health 2.0 research, e.g., for discerning disparities across population groups in certain health conditions. To recover the missing user demographic information, existing methods observe a limited scope of user behaviors, such as …
