Catalyst: Architecture for Change and Social Justice

In major cities today, there are neighborhoods that have been continually underserved and as a result are in decay. Private investors and developers turn to these particular neighborhoods, propose large developments that gentrify these areas, displacing communities and with them their social, political, and economic issues. The purpose of this thesis is to analyze South West, Baltimore, a community composed of 8 neighborhoods on the verge of being gentrified, by incoming development. Through investigating the key issues present in this community for many years, this thesis will attempt to develop a catalytic environment, which will facilitate change within the community by providing a place for its members to help tackle these issues, improving their circumstances, and the circumstances of the neighborhoods they form part of.

Urban Catalyst: Continuing the Legacy of Massachusetts Avenue

This thesis proposes a reconnection of Massachusetts Avenue to the Anacostia River waterfront in Washington, DC. An intervention at the site of Reservation 13 will reconcile a difficult urban edge and reunite the neighborhood of Lincoln Park with the river. It also addresses the discontinuity of the avenue to the southeast and proposes the development of a bridge between the Western bank and ultimately Randle Circle. Along this reconciled corridor will be a series of architectural interventions that serve to promote community involvement. Ultimately this thesis is about generating an urban continuity and the cultural vibrancy and understanding that such a connection would foster.

Motivic Decomposition of Projective Pseudo-Homogeneous Varieties

Let G be a semi-simple algebraic group over a field k. Projective G-homogeneous varieties are projective varieties over which G acts transitively. The stabilizer or the isotropy subgroup at a point on such a variety is a parabolic subgroup which is always smooth when the characteristic of k is zero. However, when k has positive characteristic, we encounter projective varieties with transitive G-action where the isotropy subgroup need not be smooth. We call these varieties projective pseudo-homogeneous varieties. To every such variety, we can associate a corresponding projective homogeneous variety. In this thesis, we extensively study the Chow motives (with coefficients from a finite connected ring) of projective pseudo-homogeneous varieties for G inner type over k and compare them to the Chow motives of the corresponding projective homogeneous varieties. This is done by proving a generic criterion for the motive of a variety to be isomorphic to the motive of a projective homogeneous variety which works for any characteristic of k. As a corollary, we give some applications and examples of Chow motives that exhibit an interesting phenomenon. We also show that the motives of projective pseudo-homogeneous varieties satisfy properties such as Rost Nilpotence and Krull-Schmidt.
