Data is asset – Evaluating the market value of databases

The topic of research concerns where SEC-licensed broker-dealers send their securities trades to be executed by financial services companies and if the payment for this order flow (PFOF) depends on the broker internalization’s market power and/or the broker-dealer’s trading volume. This research seeks to answer why certain broker-dealers send their trades to certain financial companies to execute their orders and if this reveals anything about trade practices. The SEC 606 reports that track this information are newly revised as of 2020 so this is fairly untouched public information that has had little-to-no analysis currently preformed on it. The main methodology used for data collection was simply searching through the broker-dealers websites for their 606 report which details where they send their trades to be executed and how much it costs to route orders to each firm. I tracked every broker-dealers information on an Excel spreadsheet and we will use this information to draw conclusions. We hope to find meaningful connections between broker-dealers order routing practices and the amount of market power they hold. We think there will be some connection between the amounts paid to certain companies and the amount of influence these firms have over the financial system. We don’t have any conclusions yet but we hope to start the data analysis soon. We hope to find patterns in our research that point to some conclusion on why certain companies behave the way they do with financial institutions and the implications that may have. This project hopes to shed some light on financial practices between institutions and to better explain how our financial system is structured as a whole and how much market power influences financial transactions. The results we find may help public policy makers, economists, politicians, etc., who all may use data such as this to have a basis for the functioning of our financial system.

Data is asset – Evaluating the market value of databases

The project aims to evaluate how the market value reflects the value of the firms’ data accumulation. Traditionally, the market value can be estimated using the discounted cash flow (DCF) method. This approach is flawed because the prediction of future cash flow is always inaccurate. This project uses firms’ data accumulations as inputs. Regression models are fitted to quantify the results.

Methods of exploring the effects of verb causativity on reaction time

Our research focuses on methods of studying how causativity of verbs affect our processing of them and therefore our reaction time, and how these reaction time effects can be isolated from other sentence processing effects like general lexical prediction. In a previous study conducted by Dr. Levinson, it was found that there is an added level of complexity in transitive variants of causative verbs as compared to transitive variants of non-causative, or activity, verbs. This was concluded by measuring reaction times in self-paced reading tasks of sentences with verbs of transitive and intransitive, as well as causative and non-causative variants. For example, a causative transitive verb appears in the sentence “The sun melted the ice”, whereas an example of a causative intransitive verb appears in the sentence “The ice melted”, which differs from an activity verb, such as “ate”. The complexity of causative verbs vs. non-causative verbs is something that has long been debated, and helps to better understand linguistic processing. Our research mainly focused on using different methods of studying this causativity phenomenon other than self-paced reading tasks, as well as determining the best methods for disentangling verb representations from lexical confounds.

Impact of School Policy Change on School Enrollment: Evidence from Mozambique

Enrollment in primary and secondary education in Sub Saharan Africa has lagged behind much of the rest of the world. Amongst numerous potential reasons, the fees to attend school is often considered a prohibitive barrier in accessing public education. In 2018, the government of Mozambique introduced legislation abolishing the fees for school enrollment in grades corresponding to the school-ages of 6 to 12. Previously on average, the fee for primary school is 21,410 meticas ($354 USD) per child per year for grades 1 to 5 and Mt 60,013 ($992 USD) per child per year for grades 6 and 7. This study explores the efficacy of this policy change and its external validity with respect to education in Sub-Saharan Africa.

Data is asset – Evaluating the market value of databases

The world is encountering a remarkable transformation to the digital economy. Uber, Alibaba, Airbnb…More and more large companies are having no real capital. What is the truly valuable things today for a company? It is data. Data affects a company’s valuation, from the simple question of revenue earned to different metrics that show a company’s ability. Valuation is, however, a tricky work to do today: most data are not transparent to the public, and factors are complex behind. The project aims to determine the exact factors behind company valuation, and how stock prices react to data changes.

Consentful Messaging: Giving People Agency over Online Interactions using Network Data

Our project works on developing a Chrome extension that allows Twitter users to have more control over their inbox messages and analyzes other accounts to generate potential warnings. This extension tackles the growing issue of online harassment and unsolicited messages on social media by letting Twitter users apply network-based rules on the messages and notifications. We use coding languages such as HTML, Javascript, CSS, Python, and web framework Django to create the frontend of our extension/website as well as the backend where the server runs. Team members can choose to work on the frontend, backend, or both. We will evaluate the extension by conducting a field deployment study on Twitter. We will recruit active Twitter users and ask them to use the extension for at least two weeks. Once the participants are finished using the system, they will be invited to complete a post-study survey and participate in interviews. There aren’t exactly any results or conclusions at this stage of developing the extension. We are currently still working on different parts of the project and individually working on appropriate functions/code. We plan to provide a fully functional and helpful extension that is able to reduce the issue of online harassment (on the user’s side).

Tech and Innovation in K-12 Education

Across the globe, 617 million of 1 billion students are not achieving the minimum proficiency levels in reading and math. Our research is focused on exploring technology that can help counteract this learning deficiency. To develop a comprehensive solution to this learning crisis, our research team has conducted an extensive review of scientific research related to integrating technology into education. Our solution contains a wide variety of technologies, of which are designed to improve several aspects of education, including: motivation, personalization, comprehension, feedback and assessments. Our intention is that these technologies will improve the educational experience and learning outcomes of current and future students.

Documentary Film Team

Despite media being virtually everywhere, there are issues that are under covered. This project aims to create a network of filmmakers that can work together to cover important problems ignored by mainstream media and to reach out to students that hadn’t before imagined that they could go to college and inform them of their opportunities. To gain knowledge to share with the rest of the network editing techniques have been explored through countless video tutorials, databases, and skill sharing sites. After the exploration phase these techniques were put to the test by creating a sample piece. Finally the best methods were combined and detailed in step by step tutorials on how to create the previously described samples. As the repertoire of tutorials and knowledge expanded it has been noticed that there are more opportunities to assist other filmmakers with their works. It has also been noticed that as the repertoire grew other filmmakers tended to listen to your suggestions and criticism on their projects more often. This project is still ongoing and more conclusions can be drawn at a later time as soon as more data is available.
