Description
This thesis, entitled "A Community Perspective on Alcohol Education," was conducted over a ten month period during the Spring 2014 and Fall 2014 semesters, composed by Christopher Stuller and Nicholas Schmitzer. The research involved interviewing twelve professionals from Arizona State University and the City of Tempe to gather a holistic view on alcohol education and alcohol safety as it involves the students at ASU. Upon completion of the interviews, recommendations were made regarding areas of improvement for alcohol education and alcohol safety at Arizona State University. These recommendations range from creating a mandatory alcohol education class to passing a Guardian Angel Law to creating a national network of alcohol education best practices. Through this thesis, the authors hope to prevent future alcohol related injuries, deaths, and tragedies. For the final display of this thesis a website was created. For the ease of reading, all information has been presented in text format.

Description
Due to the environmental problems caused by global warming, it has become necessary to reduce greenhouse gas emissions across the planet. Biofuels, such as ethanol, have proven to release cleaner emissions when combusted. However, large scale production of these alcohols is uneconomical and inefficient due to limitations in standard separation processes, the most common being distillation. Pervaporation is a novel separation technique that utilizes a specialized membrane to separate multicomponent solutions. In this research project, pervaporation utilizing ZIF-71/PDMS mixed matrix membranes are investigated to see their ability to recover ethanol from an ethanol/aqueous separation. Membranes with varying nanoparticle concentrations were created and their performances were analyzed. While the final results indicate that no correlation exists between nanoparticle weight percentage and selectivity, this technology is still a promising avenue for biofuel production. Future work will be conducted to improve this existing process and enhance membrane selectivity.

Description
The goal of this research project is to create a mixed matrix membrane that can withstand very acidic environments but still be used to purify water. The ultimate goal of this membrane is to be used to purify urine both here on Earth and in space. The membrane would be able to withstand these harsh conditions due the incorporation of a resilient impermeable polymer layer that will be cast above the lower hydrophilic layer. Nanoparticles called zeolites will act as a water selective pathway through this impermeable layer and allow water to flow through the membrane. This membrane will be made using a variety of methods and polymers to determine both the cheapest and most effective way of creating this chemical resistant membrane. If this research is successful, many more water sources can be tapped since the membranes will be able to withstand hard conditions. This document is primarily focused on our progress on the development of a highly permeable polymer-zeolite film that makes up the bottom layer of the membrane. Multiple types of casting methods were investigated and it was determined that spin coating at 4000 rpm was the most effective. Based on a literature review, we selected silicalite-1 zeolites as the water-selective nanoparticle component dispersed in a casting solution of polyacrylonitrile in N-methylpyrrolidinone to comprise this hydrophilic layer. We varied the casting conditions of several simple solution-casting methods to produce thin films on the porous substrate with optimal film properties for our membrane design. We then cast this solution on other types of support materials that are more flexible and inexpensive to determine which combination resulted in the thinnest and most permeable film.

Description
Modern Americans ignorantly live under a blanket of unread terms, conditions, and binding contracts. Often, these contracts (mostly associated with products and services) come and go with little effect. Periodically, the products or services cause the consumer harm, leading them to seek repair. The consumer then realizes that all the fine print they failed to read makes an impactful legal difference. This paper analyzes the work of Professor Radin through her book, Boilerplate. It goes on to explore many other arguments presented by contract theorists and makes substantial claims regarding the dangers of boilerplate (unread terms and conditions).

Description
This thesis explores three predominant theories of language in cultures, considering them with the use of multilingual automated phone systems. It presents an analysis of Internet based (primarily through blogposts) reviews of such systems. As these reviews are insufficient to form a conclusion as to how the public sees such systems, this thesis also presents an original study of 90 participants, which assesses both the functional difference between English only and multilingual systems, as well as respondents' personal ethical (as defined by participants themselves) beliefs as to the necessity of such multilingual automated systems. The study's primary hypotheses assert that these systems will not have any large functional difference, and that the majority of respondents will find the use of such multilingual automated systems ethically necessary. Both of these hypotheses are found to be correct.

Description
Trekster is an online outdoor website that provides the tools and information necessary for any person to complete a given outdoor activity that matches his/her ability, age, location, and desires with a focus on United States National Parks and National Monument travel. Over time, Trekster will create a sizable repository of trails and activities that reflect a geographically diverse nation and the equally diverse interests the population of the world seek to enjoy in these awe-inspiring locales. Trekster will focus on content creation and the updating of existing content to continually offer the most precise and voluminous information on a given trail, activity, or news item. Trekster is a Limited Liability Company with roots in Arizona and Colorado. Trekster will be managed by Kurtis Zinger, an outdoorsman and businessman keen on finding solutions to problems he has experienced in his travel planning within the national parks. The idea for Trekster originated with a lack of helpful content available from the National Park Service websites for travel to the United States National Parks and National Monuments. Visitation at parks has continued to increase most years over the past three decades, yet the National Parks Service has not been able to successfully serve the demand of an eager outdoor demographic. Trekster is designed for ease-of-use and its target market ranges from senior citizens and foreign visitors to American citizens that are avid backpackers, hikers, and/or campers. Trekster will provide these markets with the tools needed to improve their outdoor or National Park experience, especially because of the lack of these resources at other websites for a reasonable price. As revenue will be Trekster's primary revenue stream, but by keeping expenses limited to marketing efforts after the first year of operation, Trekster will reach its break-even point by 2017 and will make positive profits that grow exponentially during the years that follow. After 2020, Trekster will have content for all 50 states and will begin exploring unique ways to deliver content and explore other potential revenue sources. Trekster will be the premier online destination for travelers to National Parks and adventurers hoping to find more than a superficial introduction to a complex maze of information. By providing quality content free of charge, Trekster will become a favorite resource of outdoor enthusiasts and a source of community for those who find solace and adventure in the outdoors.

Description
The scarcity of fresh water worldwide has necessitated improved technology for desalinating sea water. Reverse osmosis membranes are currently limited by their inclination for fouling, in which a layer forms on the surface of the membrane and impedes water flux. This yields shortened membrane lifespan and increased energy costs. Current technology uses interfacially polymerized polyamide thin film composite membranes, which form nodules, leaves, and other structures that lead to rough film surfaces and may contribute to fouling propensity. In this study, polyamide latex was designed in order to cast a smoother membrane with comparable performance. Polyamide latex particles were formed using a modified procedure based on Lind et. al [10] and characterized for sphericity using scanning electromagnetic microscopy (SEM).

Description
The recovery of biofuels permits renewable alternatives to present day fossil fuels that cause devastating effects on the planet. Pervaporation is a separation process that shows promise for the separation of ethanol from biologically fermentation broths. The performance of thin film composite membranes of polydimethylsiloxane (PDMS) and zeolite imidazolate frameworks (ZIF-71) dip coated onto a porous substrate are analyzed. Pervaporation performance factors of flux, separation factor and selectivity are measured for varying ZIF-71 loadings of pure PDMS, 5 wt%, 12.5 wt% and 25 wt% at 60 oC with a 2 wt% ethanol/water feed. The increase in ZIF-71 loadings increased the performance of PDMS to produce higher flux, higher separation factor and high selectivity than pure polymeric films.

Description
In this research, construction of a model membrane system using Polyvinylidene Chloride-Co Acrylonitrile and Linde Type A zeolites is described. The systems aims to separate out flow through zeolite pores and flow through interfaces between zeolites and polymers through the use of pore filled and pore open zeolites. Permeation tests and salt rejection tests were performed, and the data analyzed to yield approximation of separated flow through zeolites and interfaces. This work concludes the more work is required to bring the model system into a functioning state. New polymer selections and new techniques to produce the membrane system are described for future work.

Description
The following paper examines the current international code of ethics and customs accompanying global supply chain management. It specifically addresses the legal aspects that contemporary supply chains must consider when conducting business internationally as well as the customary traditions associated with major regions of current trade. In particular, it describes the simultaneously growing and tepid interest in conducting business with the B.R.I.C. (Brazil, Russia, India, and China) countries to supplement the aforementioned topic with a contemporary issue. In particular, it details the amount, if any, of corruption occurring in each country and describes the influence that these practices have and the complications they create on international trade with the United States.
