Abstract
The aim of this research was to find a correlation between the Persuasion Knowledge Model and Instagram Advertisements. Past research has primarily focused on this model on other forms of media such as television, radio, newspaper, etc. Additionally, the ages studied have been over the age of 30 as well as not focused within a certain geological demographic. For this study, participants were residents of Pennsylvania who vary in age between 18-25 years old. Using a survey, statistical analysis, and Pearson Product Moment Correlation Coefficient Analysis test (PCC test), this study measured each of the 49 participants’ persuasion knowledge and correlated it to the advertisements chosen in the survey. The analyses found that those with lower persuasion knowledge were more likely to select an advertisement with less text variance and influential text. Further, a new understanding was found that showed a slightly negative correlation due to the PCC test, but the correlation was not statistically significant. Therefore, the findings of this research study refuted the initial hypothesis and other studies conducted in the field of persuasion knowledge.
This research study looked at the efficacy of infield softball face masks at reducing concussion risk. The primary goal of this research was to contrast head accelerations experienced during softball impacts for different brands of softball face masks. In order to achieve this goal, a surrogate headform equipped with different brands of face masks was impacted at a constant impact location and ball speed. The resulting headform accelerations (linear and rotational) were collected with a Vernier accelerometer upon each impact and analyzed. The results of the study showed that all tested brands of face masks were successful at reducing head acceleration severity. Moreover, significant differences in performance were observed between the different brands of face masks. One can conclude from this research that particular brands of face masks can more effectively reduce concussion risk because they better reduce head acceleration values. Due to the study results, softball players may have a better understanding of face mask performance, which could lead to higher mask implementation in the sport and an overall reduction in softball-related concussion occurrence.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
