Item Forward The New Stage Of Democracy: Perceptions On Disability And Employment Discrimination After The Americans With Disabilities Act Of 1990(University of Delaware, 2016-05) Chung, Jae WooDespite decades of disability movement and the Americans with Disabilities Act of 1990, many people with disabilities are still excluded and discriminated in various areas of life, including the workforce. The primary reason for such exclusion is that our society is exposed to ableist standards, which often either undermine or exaggerate the life with a disability. Since this is more of structural discrimination, most people often unintentionally impose these standards and bias. As a result, reevaluation of disability is need for a more inclusive model of democracy. In many aspects, the Title 1 of ADA tries to remedy such ableism by explicitly prohibiting employment discrimination. But what law can do is limited. It cannot always penetrate into our cultural and social values. Given the limits of law, I examine how well the ADA corresponds to Martha Nussbaum’s capabilities approach and how it has progressed through the Supreme Court cases till the Amendments Act of 2008. This study mainly involves a theoretical analysis of different philosophers and a legal analysis of the court cases, hoping to sketch a new stage of democracy that can be more inclusive.Item Imaging the lower limb network in Parkinson’s disease(NeuroImage: Clinical, 2023-04-13) Chung, Jae Woo; Bower, Abigail E.; Malik, Ibrahim; Martello, Justin P.; Knight, Christopher A.; Jeka, John J.; Burciu, Roxana G.Background Despite the significant impact of lower limb symptoms on everyday life activities in Parkinson’s disease (PD), knowledge of the neural correlates of lower limb deficits is limited. Objective We ran an fMRI study to investigate the neural correlates of lower limb movements in individuals with and without PD. Methods Participants included 24 PD and 21 older adults who were scanned while performing a precisely controlled isometric force generation task by dorsiflexing their ankle. A novel MRI-compatible ankle dorsiflexion device that limits head motion during motor tasks was used. The PD were tested on their more affected side, whereas the side in controls was randomized. Importantly, PD were tested in the off-state, following overnight withdrawal from antiparkinsonian medication. Results The foot task revealed extensive functional brain changes in PD compared to controls, with reduced fMRI signal during ankle dorsiflexion within the contralateral putamen and M1 foot area, and ipsilateral cerebellum. The activity of M1 foot area was negatively correlated with the severity of foot symptoms based on the Movement Disorder Society‐Sponsored Revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS-III). Conclusion Overall, current findings provide new evidence of brain changes underlying motor symptoms in PD. Our results suggest that pathophysiology of lower limb symptoms in PD appears to involve both the cortico-basal ganglia and cortico-cerebellar motor circuits.
