Description
The US National Academy of Sciences and The Royal Society have recently released a detailed report on the causes and effects of global climate change.1 This report states that the Earth’s climate is rapidly changing due to human activity. Specifically, the burning of fossil fuels to satisfy the energy demands of rising global population has resulted in unprecedented levels of greenhouse gasses in the atmosphere. These high levels of greenhouse gasses are serving to warm the surface of the planet resulting in extreme weather events. Thus, controlling the atmospheric CO2 level is motivating a great deal of scientific research in the area of carbon capture and storage (CCS).
Despite the great strides being made in the areas of alternative energy and solar-energy conversion, consumption of fossil fuels for energy generation will likely continue into the foreseeable future. This is primarily motivated by economic factors inasmuch as fossil fuels are a proven resource base with robust harvesting and distribution infrastructure.2 Presently, there are more than 8,000 stationary CO2 emission sources with an annual output of 13,466 megatons of CO2 per year.2 In this context, development of systems that ameliorate the output of greenhouse gasses from stationary CO2 sources, such as coal and natural gas burning power plants, is urgently needed.
In this document the utility of sulfur nucleophiles for CCS schemes is explored. The main thrust of the research has been utilizing electrogenerated sulfur nucleophiles to capture CO2, which can be electrochemically recovered from the resulting thiocarbonates while concomitantly regenerating the masked capture agent. Further, a temperature swing CO2 capture scheme that employs benzylthiolate as the CO2 sorbent is proposed and methods of manipulating the release temperature and kinetics were investigated. These reports represent the first application of organosulfur compounds toward CCS technologies and there are a number of newly reported compounds. The appendix deviates from the theme of the first four chapters to describe the functionalization of poly(2,6-dimethyl-1,4-phenylene oxide) with ferrocene moieties by the copper catalyzed azide-alkyne coupling reaction. This material is discussed within the context of anion recognition and sensing applications.

Description
With the new independence of adulthood, college students are a group susceptible to adopting unsupported, if not harmful, health practices. A survey of Arizona State University undergraduate students (N=200) was conducted to evaluate supplement use, trust in information sources, and beliefs about supplement regulation. Of those who reported using supplements, college students most frequently received information from friends and family. STEM majors in fields unrelated to health who were taking a supplement were found to be less likely to receive information about the supplement from a medical practitioner than those in health fields or those in non-STEM majors (-26.9%, p=0.018). STEM majors in health-related fields were 15.0% more likely to treat colds and/or cold symptoms with research-supported methods identified from reliable sources, while non-health STEM and non-STEM majors were more likely to take unsupported cold treatments (p=0.010). Surveyed students, regardless of major, also stated they would trust a medical practitioner for supplement advice above other sources (88.0%), and the majority expressed a belief that dietary supplements are approved/regulated by the government (59.8%).

Description
I propose that norms regulate behaviors that negatively impact an individual's survival and reproduction. But because monitoring and enforcing of norms can be costly, individuals should be selective about which norms they police and under what circumstances they should do so. Two studies tested this idea by experimentally activating fitness-relevant motives and having participants answer questions about the policing of norms. The first study examined a norm prescribing respect for status and another proscribing sexual coercion. Results from Study 1 failed to support the hypotheses; activating a status-seeking motive did not have the predicted effects on policing of the respect-status norm nor did activating a mating motive have the predicted effects on policing of the respect-status norm or anti-coercion norm. Study 2 examined two new norms, one prescribing that people stay home when sick and the other proscribing people from having sex with another person's partners. Study 2 also manipulated whether self or others were the target of the policing. Study 2 failed to provide support; a disease avoidance motive failed to have effects on policing of the stay home when sick norm. Individuals in a relationship under a mating motive wanted less policing of others for violation of the mate poaching norm than those in a baseline condition, opposite of the predicted effects.

Description
Literature in public administration emphasizes a growing dissatisfaction with government on the part of residents. Where there tends to be a lack in the literature is in terms of solutions to this problem. We would like to argue that the engagement process itself has the power to foster a profound attitudinal shift on the part of both residents and government. This paper explores the structural and cultural barriers to satisfactory public engagement both from literature and a combination of policy analysis, semi-structured interviews and participatory observation within the City of Tempe. We then provide recommendations to the City of Tempe on how to overcome these barriers and effect authentic public engagement practices. With these new suggested practices and mindsets, we provide a way that people can have the power to create their own community.

This thesis examines the relationship between unofficial, official, and parallel Islam in Uzbekistan following the end of the Soviet Union. Key touchstone moments in Uzbekistan during the twentieth-century show the history between unofficial and official Islam and the resulting precedents set for Muslims gathering against the government. This historical analysis shows how President Karimov and the Uzbek government view and approach Islam in the country following independence.

Teen dating violence is a significant problem in the U.S., with approximately 1 out of 3 teens experiencing some form of dating violence. BLOOM is a not-for-profit organization created by Donna Bartos. BLOOM's educators enter high schools in Arizona and present their educational program on dating abuse prevention. BLOOM's primary goal is to educate teens on how to prevent teen dating violence and empower them with the skills leading to healthy relationships. After participants complete their educational program, a feedback card is filled out with an open-response section. This project focused on the open response section to analyze feedback cards through a process of code development, coding, and tallying. Information provided by this project could assist BLOOM in re-evaluating their curriculum, appealing to future investors, and growing their program to reach more students. With a coding system in place, BLOOM will also be able to better assess the impact they have on the participants of their program.

Description
The Islamic State also known as ISIS is an organization and a self-proclaimed state that emerged from many diverse factors. Its roots lie with Abu Musab al-Zarqawi (1966—2006), the 2003 invasion of Iraq and the ideologies of various modern-day Jihadi-Salafist. ISIS proclaimed a world-wide Caliphate in 2014 and named Abu Bakr al-Baghdadi as its Caliph. Muslim, non-Muslim states and Islamic authorities however, rejected its claim to statehood or caliphate. The goal of this thesis is to understand the development of this new phenomenon by analyzing its history, rhetoric, ideology and practice. Prior to its creation, the tensions in Iraq during the Saddam Hussein regime and its relationship to the first and the second Iraq war in 1990-91 and 2003 as well as the creation of Al-Qaeda in Afghanistan that led to the emergence of a new phenomenon, global jihadism. The main ideology that the Islamic State promotes is a form of Jihadi-Salafism that claims to unite Muslims against all non-Muslim governments in order to bring “true Islam” back into the world. To do this, jihadists justify the establishment of the Caliphate in an effort to provide legitimacy to their actions, appealing to young people who often times are seduce by their eschatology. Once individuals join, they are taught concepts pertaining to martyrdom to establish loyal to the organization and its cause. To win people over, the Islamic State employs modern methods of communication that includes social media such as Youtube and Twitter, as well as magazines such as Dabiq. These resources address the online community and specifically attract individuals who feel isolated from their communities, or individuals who wish to create an impact on the world. Overall, the Islamic State, although it employs Islamic symbols and scriptures in their claim of representing all Muslims, does not adhere to, nor respect the historical and intellectual discussions of Islam in favor of their own political agenda. Its adherents utilize concepts from certain Salafi and Wahhabi ideals, emphasizing jihad as defensive war against the West in an attempt to isolate parts of society so that they can retain control. They ignore the main concept of mercy within the Islamic faith. Muslims in the Arizona community agree that the Islamic State is not a representation of Islam in this world and should not be equivocated with the Islamic practices that more than 1.6 billion Muslims practice in their daily life.

Afghani women's resistance: their struggle for autonomy under the Soviet Occupation and Taliban rule
Description
The American-led 'war on terror' affected how media outlets and some contemporary literature addressed and stereotyped Islam. One of the most common stereotypes regarded the status of women in society. The constant images of oppressed Afghani women generated a wave of negativity toward Islam. Afghani women were portrayed as passive characters during the Taliban rule awaiting liberation from the west. Defending their rights became one of the moral justifications for waging the 'war on terror' after the tragedy of 9/11. Gender politics in Afghanistan is closely tied to the regime in power. The Soviet invasion of Afghanistan in 1979 and the social and cultural transformation of society that followed also directly affected women and their identity as Muslims. Both the Soviet and the Taliban regimes envisioned a drastic transformation of women's participation in the public sphere. Each regime's gender politics oppressed Afghani women and sought to take away their agency. Some women welcomed the freedom under the Soviets, but others found the freedoms to be oppressive. The Taliban aimed to preserve men's authority over women. However, Afghani women never gave up the hope of freedom and equality. My main argument is to challenge the contemporary belief that Afghani women were passive characters in their history. This study introduces a fresh perspective on to women's role as change makers in the society. I argue that Afghani women maintained their autonomy and fought for their rights, before the rest of the world rushed to liberate them. They engaged in different forms of resistance from directly attacking the oppressors to keeping their resistance hidden. This thesis challenges the notion of Afghani women as victims in need of saving. On the contrary, they were the agents of change in their communities. On the basis of ethnographic interviews and three memoirs written by women who lived in Afghanistan during Soviet and Taliban rule. Their resistance against the oppressors is an affirmation of their courage and bravery.
