This thesis will encompass the chemical, social, cultural, and even religious significance and history of Henna. Henna is a natural paste made out of dried henna leaves which is then mixed with other ingredients such as lemon juice, tea, essential oils, and sugar. Depending on the region, everyone uses a different recipe and ratios due to the different climates. Henna has been used for celebrations such as weddings in Western Asia, the Middle East, and even Africa. Henna has also been used in religious celebrations for Muslims such as Eid. The practice of henna application has proven to be a uniting factor in multiple cultures, as women gather to get their henna done for celebrations and joyful occasions. Despite its cultural significance, henna was actually used medicinally in ancient times due to its cooling properties. People used to dye the soles of their feet, and hands during the summer in order to cool down their bodies. Slowly, henna became more of a beauty factor and women began to make designs with it to adorn themselves. Applying henna is a lengthy process. Henna must dry for about 30 minutes before one is able to continue with daily routine. Then the henna must be wrapped after being soaked in a lemon sugar solution. This must remain for 5+ hours in order to achieve the desired intensity of the stain. However, once the dry henna is taken off, no water must touch the premature stains for 24 hours since this is when the henna begins to oxidize and the color begins to darken. It takes 48 hours for the henna stain to fully mature. Due to this, chemical henna, otherwise known as “instant henna” has been created to make that dark mature stain in a matter of a few hours, sometime even minutes. There are two downsides: the first being that the stain does not last 1-2 weeks like the natural henna does, the second being it is a major health risk. Most of these prepackaged chemical henna cones contain additives that are used to dye hair. This dye is not meant to be used on skin, so many people have gotten chemical burns due to this. It can even lead to full-on allergic reactions resulting in hospital-stays. The use of chemical henna not only poses health risks, but it also diminishes the value of henna and what it stands for. This project will dive into the following questions: How does henna stain the skin? How has Henna impacted women throughout the world? What is the artistic significance of Henna? What aspects of Henna have allowed it to be integrated into cultures throughout the years? How can one avoid the use of chemical henna, and what kind of potential risks arise from this?

The policy design process in the United States has been guiding policymakers for decades. In order to keep up with the developing sustainability challenges that the US is facing, a new method of policy design needs to be determined for long-lasting, sustainable change. Human-centered design principles provide a new, unique perspective for analyzing sustainability challenges. Through the integration of human-centered design principles into policy systems, a new framework for policy design can be created. Through this project, a new framework that allows for the adaptation to new technologies, scientific information, and developments in the sustainability crisis to be accounted for and adequately addressed in future policies has been created.

The outlying cities of Phoenix's West Metropolitan experienced rapid growth in the past ten years. This trend is only going to continue with an average expected growth of 449-891% between 2000 and 2035 (ADOT, 2012). Phoenix is not new to growth and has consistently seen swaths of people added to its population. This raises the question of what happened to the people who lived in Phoenix's West Valley during this period of rapid change and growth in their communities? What are their stories and what do their stories reveal about the broader public history of change in Phoenix's West Valley? In consideration of these questions, the community oral histories of eight residents from the West Valley were collected to add historical nuance to the limited archival records available in the area. From this collection, the previous notion of "post-war boomtowns” describing Phoenix’s West Valley was revealed to be highly inaccurate and dismissive of the residents' experiences who lived and formed their lives there.
