Planning Cities, Economically Or Communally: A Comparative Study Of Amsterdam And San Francisco, Raina Dawn Whittekiend

Master's Theses

Globalization has spun “community” off its axis. What once defined community is no longer the current state of the community. Increased economic transactions have led to the instability of communities that once depended on one another at the local level. These communities are now dependent on systems that do not know nor understand their actors. This lack of relationship between development and subject is witnessed and highly scrutinized in developing countries all over the world and has been intensely researched in academic literature. This thesis intends to better understand why in modernized global cities these same processes of development and …

Reconciling The Challenge Of Aphanic Species Within Marine Conservation, Kerri L. Bolow

HCNSO Student Capstones

Aphanic species are those within a taxonomic complex that may not be readily distinguishable from other sympatric species. The existence of these species is becoming apparent at an increasing rate through the use of technological tools like molecular genetic analyses. A lack of clarity on the definitions of terms used to describe similar species, how these species are identified, and how prevalent they are can confound identification, description, and management of these organisms. This review collects and defines the terms used to describe these hidden species and suggests the use of the term aphanic for situations where additional information (and …

Housing The Homeless: A Framework For Sustainable, Affordable Housing, Brianna Providence

Student Theses 2015-Present

New York City’s building stock is comprised of nearly one million structures. Buildings are responsible for unconscionable amounts of global energy, water, resources, and greenhouse gas (GHG) emissions. Thousands of buildings are annually constructed when the truth is that there is a significant stock of buildings that could stand to be rehabilitated. New green developments present an opportunity to increase efficiency while reducing energy use, resource consumption, and waste. If virgin new green developments provide the aforementioned opportunities, then it logically follows that sustainably retrofitting preexisting buildings represents an even greater opportunity to promote environmental sustainability and reduce inefficiencies.
