Interactions Between the Urban Environment and “The Homelessness”: Observations and Responses

Homelessness and people living on the streets is a phenomenon that is facing every major urban center in the United States. These people are a commonality in the urban landscape and are often seen a problem to be fi xed. Due to the interactions between the urban environment and persons experiencing homelessness, there needs to be a paradigm shift in how policy is written and how we design an intervention for these forgotten people. The goal of this thesis is to gain a clearer understanding to what it is like to survive on the streets: how dose someone fi nd shelter in the urban environment? This research also examines the reasons, if any, that homeless people do not always use the homeless shelters at their disposal. The data for this project was taken from direct personal observation and fi rst-hand account from homeless individuals. Many homeless people keep a blog and provide detailed information about their experiences on the street. Using this information, I have created a possible design solution to the issues raised by the research. This is not an example of what should be done but rather an example of what could be done when there is greater understanding of the homeless culture. “You can easily judge the character of a man by how he treats those who can do nothing for him.” -Johann Wolfgang von Goeth

Topologically stable ergodicity breaking from emergent higher-form symmetries in generalized quantum loop models

We present a set of generalized quantum loop models which provably exhibit topologically stable ergodicity breaking. These results hold for both periodic and open boundary conditions, and derive from a one-form symmetry (notably not being restricted to sectors of extremal one-form charge). We identify simple models in which this one-form symmetry can be emergent, giving rise to the aforementioned ergodicity breaking as an exponentially long-lived prethermal phenomenon. We unveil a web of dualities that connects these models, in certain limits, to models that have previously been discussed in the literature. We also identify nonlocal conserved quantities in such models that correspond to a pattern of system-spanning domain walls, and which are robust to the addition of arbitrary $k$-local perturbations.Comment: 22+8 pages, 8 figure

Emotion Work in Experience-Centred Design

Experience Centred Design (ECD) implores us to develop empathic relationships and understanding of participants, to actively work with our senses and emotions within the design process. However, theories of experience-centred design do little to account for emotion work undertaken by design researchers when doing this. As a consequence, how a design researcher’s emotions are experienced, navigated and used as part of an ECD process are rarely published. So, while emotion is clearly a tool that we use, we don’t share with one another how, why and when it gets used. This has a limiting effect on how we understand design processes, and opportunities for training. Here, we share some of our experiences of working with ECD. We analyse these using Hochschild’s framework of emotion work to show how and where this work occurs. We use our analysis to question current ECD practices and provoke debate

Thermal Testing of a Stacked Core Mirror for UV Applications

The ASTRO2010 Decadal Survey stated that an advanced large-aperture ultraviolet, optical, near-infrared (UVOIR) telescope is required to enable the next generation of compelling astrophysics and exoplanet science; and, that present technology is not mature enough to affordably build and launch any potential UVOIR mission concept. Under Science and Technology funding, NASA's Marshall Space Flight Center and ITT Exelis have developed a more cost effective process to make 4m monolithic spaceflight UV quality, low areal density, thermally and dynamically stable primary mirrors. A proof of concept mirror was built and tested down to 250K which would allow imaging out to 2.5 microns. This mirror was thermally tested at the Marshall Spaceflight Center to understand the thermal changes between the processing temperature of 293K and the potential low end of the operational temperature of 250K. Isothermal testing results and front plate gradient results have been evaluated and compared to analysis predictions. Measurement of gravity effects on surface figure will be compared to analytical predictions. Future testing of a larger Pathfinder mirror will also be discussed
