Analysis Of Us Airline Stocks Performance Using Latent Dirichlet Allocation (Lda), Amina Issoufou Anaroua
Beyond: Undergraduate Research Journal
Various events, such as changes in the interest rate or the hijacking of a commercial aircraft, can lead to significant shifts in airline stock performance. This study aimed to measure the impact of aviation-related news announcements on the stock performance of US airlines, focusing on different topics. The dataset included aviation news covering airlines, airports, regulations, safety, accidents, manufacturers, MRO, incidents, aviation training, general aviation, and others obtained from Aviation Voice. To uncover patterns that could explain the movements of US airline stocks, a natural language processing technique called Latent Dirichlet Allocation (LDA) was employed. The process involved text mining …

Primacy And Recency Effects On Position Error In Short-Term Memory Recall, Weerachet Sinlapanuntakul, Kelly Harris, Brittany S. Wesley

Position error is the most common error in serial recall of short-term memory, especially when environment, language, or similarity factors are presented. Previous studies demonstrate some support for the serial recall resulting in less error-prone for the first and last positions than the middle positions. This study investigates the accuracy of recalling letters and their positions when given a random sequence with minimal to no external factors. The significant predictors influencing position error were the primacy and recency effects. Participants completed a 20-trial experiment on the CogLab Experimental Control Software, which presented a series of letters one at a time …

Cuban Vintage Car Culture, Zachary H. White
Beyond: Undergraduate Research Journal
The purpose of this research was to investigate the culture surrounding the vintage American cars found in Cuba. Through preliminary research, the researcher determined Cubans are continuing to use these cars as a means of transportation as well as a source of income. They have kept the cars maintained by recycling parts from other cars, tractors, and boats, as well as buying new parts from the black market. Once they have been repaired, many owners around major cities use them as taxis. This is so that the owners can afford to maintain them as well as provide additional income for …
