Aphasia is an acquired speech-language disorder that is brought upon because of post-stroke damage to the left hemisphere of the brain. Treatment for individuals with these speech production impairments can be challenging for clinicians because there is high variability in language recovery after stroke and lesion size does not predict language outcome (Lazar et al, 2008). It is also important to note that adequate integration between the sensory and motor systems is critical for many aspects of fluent speech and correcting speech errors. The present study seeks to investigate how delayed auditory-feedback paradigms, which alter the time scale of sensorimotor interactions in speech, might be useful in characterizing the speech production impairments in individuals with aphasia. To this end, six individuals with aphasia and nine age-matched control subjects were introduced to delayed auditory feedback at 4 different intervals during a sentence reading task. Our study found that the aphasia group generated more errors in 3 out of the 4 linguistic categories measured across all delay lengths, but that there was no significant main effect delay or interaction between group and delay. Acoustic analyses revealed variability among scores within the control and aphasia groups on all phoneme types. For example, acoustic analyses highlighted how the individual with conduction aphasia showed significantly longer amplitudes at all delays, and significantly larger duration at no delay, but that significance diminished as delay periods increased. Overall, this study suggests that delayed auditory feedback’s effects vary across individuals with aphasia and provides a base of research to be further built on by future testing of individuals with varying aphasia types and levels of severity.

A Conversation on Stuttering is a documentary film that is aimed at raising awareness about stuttering. Still not fully understood by modern research, stuttering (stammering in the UK) is a diagnosis often accompanied by years of ridicule, shame, and misconceptions. We set out to interview people who stutter, researchers, and clinicians alike to gain insight into the impact stuttering can have. Our participants in this documentary included four people who stutter, two clinicians, and 2 researchers (one of them being a person who stutters). The questions asked ranged from topics of physical and emotional aspects of stuttering to therapy experiences and research on what causes stuttering. From the mix of genuine, sometimes emotional, responses, the film captures flowing conversation on a range of experiences had by our interviewees. Through these responses, we hope to open further dialogue about the themes of identity, understanding our differences, and perspectives that can make a more accepting world.

Public health and urban planning are tightly linked, yet their intersection is not always addressed in courses. Urban planning plays a critical role in determining a city’s environmental impact, transportation infrastructure, walkability, and so much more. Creating a class that explores the ways urban planning and public health connect for pre-med and public health students is important because their education shapes the type of health advocates they become. Ultimately, understanding urban planning provides future public health advocates and doctors with a new toolset to improve the public’s health and produce healthier cities. This creative project aims to address this issue by creating a class with 15 modules showing the various ways that urban planning and public health intersect.

This thesis reviewed variables of baseball mechanics and performance as discussed in current literature. This included investigating factors of biomechanics, the health of players, and comparisons across demographics. At the biomechanical level, components of the kinetic chain were observed as the energy transferred from the lower body to the upper body. Additionally, the upper body appeared to compensate for deficits in the rotation of the trunk. Injuries to the abdominal and low back were correlated with trunk rotation, while arm injuries were traced back to overuse and fatigue. When considering experience level, variation tended to decrease. Youth players demonstrated different patterns of fatigue and different injury correlates compared to adults. At a geographic level, American pitchers may be associated with an increased risk of elbow injuries, with Japanese and Korean pitchers to shoulder injuries; these differences are thought to be due to differences in instruction. Applying this research and findings to current baseball players may help guide training and performance or continue research.
