Research suggests there is no significant difference in outcomes for online learners and on-campus learners. Several decades of online learning have also consistently demonstrated online students are less likely to persist than those students attending on campus. The Community of Inquiry (CoI) framework describes social presence, teaching presence, and cognitive presence as components of a quality online learning experience, and research links these three constructs to student retention. Using the lens of the CoI framework, this mixed methods action research study sought to increase social presence and teaching presence in asynchronous online courses at Davenport University using embedded video feedback mechanisms, in support of student persistence and retention. The Community of Inquiry survey instrument was used to quantitatively measure the changes in social presence and teaching presence between courses with and without the video feedback mechanisms. Qualitative research interviews were conducted to probe for meaning and a greater understanding of both student and instructor experiences in the courses. Results of the study indicated small but significant gains in teaching presence, but other quantitative measures showed no changes with the introduction of the videos. Qualitative analysis suggests that students who watched the instructor videos reported higher levels of teaching presence for several subconstructs of teaching presence and social presence. However, the qualitative analysis also suggested that many students did not watch the instructor videos, and thus did not benefit from any increased presence. Student discussion response videos yielded similar results qualitatively, with benefits demonstrated by those students who watched the videos but none by those who abstained.

Cain's Jawbone is a puzzle book written in 1936, detailing 6 murders in 100 pages. However, it is up to the reader to not only figure out who kills who, but also what order the events happen in. With multiple narrators- none explicitly named- it is a seemingly impossible task. In the 90 years since publishing, only 3 people have successfully solved it. A contest started in 2018 to see who could solve it by December of 2022- the winner receives a cash prize of $350. This thesis will detail my process of solving the book, as well as (part) of my proposed solution. In the spirit of fairness for the competition, I will not submit my proposed page order- but I will go into great detail of what I believe happens, as well as who murders who.

Description
Despite an abundance of defenses that work to protect Internet users from online threats, malicious actors continue deploying relentless large-scale phishing attacks that target these users. Effectively mitigating phishing attacks remains a challenge for the security community due to attackers' ability to evolve and adapt to defenses, the cross-organizational nature of the infrastructure abused for phishing, and discrepancies between theoretical and realistic anti-phishing systems. Although technical countermeasures cannot always compensate for the human weakness exploited by social engineers, maintaining a clear and up-to-date understanding of the motivation behind---and execution of---modern phishing attacks is essential to optimizing such countermeasures.
In this dissertation, I analyze the state of the anti-phishing ecosystem and show that phishers use evasion techniques, including cloaking, to bypass anti-phishing mitigations in hopes of maximizing the return-on-investment of their attacks. I develop three novel, scalable data-collection and analysis frameworks to pinpoint the ecosystem vulnerabilities that sophisticated phishing websites exploit. The frameworks, which operate on real-world data and are designed for continuous deployment by anti-phishing organizations, empirically measure the robustness of industry-standard anti-phishing blacklists (PhishFarm and PhishTime) and proactively detect and map phishing attacks prior to launch (Golden Hour). Using these frameworks, I conduct a longitudinal study of blacklist performance and the first large-scale end-to-end analysis of phishing attacks (from spamming through monetization). As a result, I thoroughly characterize modern phishing websites and identify desirable characteristics for enhanced anti-phishing systems, such as more reliable methods for the ecosystem to collectively detect phishing websites and meaningfully share the corresponding intelligence. In addition, findings from these studies led to actionable security recommendations that were implemented by key organizations within the ecosystem to help improve the security of Internet users worldwide.

Today, we are experiencing a world where Net Neutrality exists in most of the countries around the world except a handful. Who knows if this will be the case in 10 years? An economy shifting from net neutrality to non-net neutrality could have an effect of wiping out an entire industry of start-ups and innovation. The main stakeholders in this industry are the Internet Service Providers (ISPs), who provide services to access, use and participate in the Internet such as AT\&T, Verizon and T-Mobile. The other main stakeholders are the Content Providers (CPs), who provide information or content to the end users through websites such as Netflix, Google, Wikipedia, etc. Before diving into the effects it has on the economy, let's discuss a little about what net neutrality and non-net neutrality really means and their pricing strategies. Typically in an economy where net neutrality exists, the ISPs charge a fixed price to the CPs and the end-users. The ISPs tend to compete on price in order to attract the CPs to use their service for content due to tight competition among the ISPs to capture profits. Thus, these costs to the CPs would be minimal, encouraging individuals from all over the world to innovate and provide content to the end users. The price burden in this case would fall not on the CPs but on the end users. But, ISPs may not be able to over charge the end users either, as they would lose their demand due to competition from other ISPs. Therefore, in spite of being the bearers of heavy investment costs to improve network quality, the ISPs haven't been enjoying profits for a long time. Meanwhile, the CPs are gaining large profits with minimal investment costs thanks to their market power over the ISPs.

The Internet has slowly over the past couple of decades has evolved greatly while also growing into its own community. Websites such as Facebook, Twitter, and even YouTube have developed their own trends, cultures, and communities. Certain people have chosen to earn their livelihood over the Internet through websites and deals with companies. In these dealings, legal matters start to take a major role as people try to review and utilize other peoples’ work to supplement their own. As a Business Law major, I aimed to delve into the legal troubles and dealings of those who wish to form a career on the website YouTube. While the intent of the work is to be informational, I will conclude with what I believe to be improvements possible for the system based on information found. With all the evidence considered, I will advocate for changes to the manual claim system by increasing human moderation as well as necessitating manual review prior to deletion of channels.

Description
This thesis was written to discuss the implications from the implementation of the Internet, and the long-term impacts that may arise. In this thesis, I go over several benefits and negatives from the internet. I start going over virtual communities in the first section because based on my research, I believe these are the biggest benefits that have arised from the integration of the internet in today's society. I move on to discuss the general benefits, and how the internet satisfies basic human needs, and has influenced our culture to move towards online activities. I move on to talk about the negatives associated with the internet, specifically talking about internet addiction because research surrounding the impacts of the internet is mainly geared towards internet addiction. This is because there is very little research regarding effects of the internet long-term due to how recent the internet is, and because there has not been much incentive to research the long-term impacts. Now because of Covid19, we are going to be seeing more research, and I came to the conclusion that our society is becoming addicted to the internet, and that we do not yet know if this is a bad thing or not. More research needs to be conducted.
