Description
The &ldquoMormon; Colonies” in Chihuahua, northern Mexico, boast a sizable population of women originally from the United States who have immigrated to these small Mexican towns. This ethnographic study of the immigrant women in the area focuses on questions of citizenship and belonging, and bolsters the scholarship on U.S. American immigrants in Mexico. Using data from 15 unstructured interviews, the women&rsquos; experiences of migration provide a portrait of U.S. American immigrants in a Mexican religious community. Analysis of this data using grounded theory has revealed that these U.S. American women have created a third social space for themselves, to a large degree retaining their original culture, language, and political loyalty. Their stories contribute to the literature on transnational migration, providing an account of the way migrants of privilege interact with their society of settlement.

Description
The economic crisis in 2008 triggered a global financial shockwave that left many wondering about the origins of the crisis. Similarly, in the early twentieth century, Wall Street faced catastrophic losses that set the stage for the Great Depression, which resulted in a decade of economic depression, leaving millions of people out of work. Using discourse analysis to understand how economic crisis is framed through the mainstream press, this research project analyzed the stock market crash of 1929-1932 and the mortgage-backed financial crisis of 2007-2009 through the lens of two mainstream publications, The New York Times and The Wall Street Journal. Comparative analysis focused on explanations for the causes of the crises, attributions of blame, culprits, and proposed solutions emerging in news coverage of the 1929 panic and the 2007-2009 financial crises. Mainstream media accounts of the 2007-2009 crisis are then compared with `alternative media' accounts of crisis causes, culprits, and solutions. These comparative analyses are contextualized historically within economic paradigms of thought, beginning with the classical economists led by Adam Smith and transitioning to the Chicago School.

Description
This ethnographic study contributes to the literature on Latin@ youth in the US by focusing on the experiences of Latin@ youth in Arizona and their identity management practices. The data from 9 months of field observations and 11 unstructured interviews provides a vivid picture of the youth's daily encounters. Using a thematic analysis this study reveals the youth's experiences in occupying predominantly white spaces, managing privilege, and managing negative stereotypes. The youth's involvement at El Centro, an Arizona nonprofit organization, provided them a safe space in which they created a familial environment for themselves and their peers.

Description
Research literature and popular press articles were reviewed to uncover the influences and viewer pleasures received from watching reality television. A close semiotic analysis of the reality television program, Teen Mom, was conducted. The semiotic analysis looked at the characters, the structure of the show, and the show's use of graphics and audio to understand the show's influences on viewers. An analysis of the Teen Mom website and online forum was also conducted. Seventy-one viewer posts and 403 viewer responses were analyzed to uncover viewer reactions to the show. The results were significant in three ways. First, the producers of the show claim the show is meant to educate viewers on the effects of teen pregnancy. The analysis found that while the show sends educational messages, it also contradicts itself by glamorizing teen pregnancy. Second, the analysis of the online forum revealed the formation of close online communities among Teen Mom viewers. Third, the website analysis provided evidence of viewer pleasure resulting from voyeuristic and social comparison tendencies. It is plausible that Teen Mom viewers engage with the show for the opportunity to observe parts of other people's lives they would not normally be permitted to see. At the same time, viewers evaluate themselves in comparison to the Teen Mom cast members.

Description
Heroism is a phenomenon central to the development of Western Society. It is present at the core of understanding history, it is the basis for all literature, and exists in many forms in contemporary society, including the celebrity. As a result of its pervasiveness, the philosophy by which heroism ought to be understood has been left out of its contemporary iterations. Through an investigation of a provocative real person, rather than a literary character, the being of the hero in the everydayness of life can be more readily understood. The character in question is Leila Khaled, provocative because she is a member of the Popular Front for the Liberation of Palestine and participated in two airplane hijackings. The general public understands her to be a terrorist; however, she is a hero among her own people and as a hero has much to teach. Through an inspection of her story, the hero presents itself as acting with courage and being motivated by love toward a greater good. Thus, an investigation of these phenomena - courage, love, and the greater good - will result in a better understanding of the hero that works toward the philosophic discussion about heroism that has been largely ignored over the last several hundred years.

Description
Using a critical textual approach and a feminist lens, this paper analyses the television adaptation, Outlander, and its depictions of sexual violence. The nature of adaptation and how the adaptation process can lead to incidental as well as intentional alterations in the storytelling are addressed throughout the paper. The analysis is done in two parts, the first exploring emergent themes such as the use of bodies’ geographic location, scars, and nudity to depict messages about power, the impact of the adaptation’s choice to promote Jamie’s perspective, and the use of cinematic techniques as narrative devices. The second half of the analysis covers how notable characters and events are framed by the show to promote a division between pure evil (embodied by Capt. Randall) and the heroes of the story, Claire and Jamie, whose problematic behaviors are minimized or promoted by the narrative. Many of the scenes in the show can be read multiple ways, sending different or even contradictory messages. However, despite the positive critical response to the show, this paper argues that Outlander still reinforces the notion that female characters are natural victims, and undermines the trauma of their assaults, in contrast to the focus given to the rape of Jamie, the heterosexual male lead.

Description
The focus of human decomposition studies has traditionally been on how external factors affect the decomposition of a body. There is much less literature on how the decomposition of a human cadaver affects its local ecosystem. This study attempts to address the knowledge gap in current literature regarding how the decomposition of human cadavers affects the bioavailability of essential plant nutrients (P, K, Ca, Fe, C and N) as well as toxins (As and Pb) in soil. By studying the bioavailability of plant nutrients, especially nitrogen, and toxins, this research hopes to inform new technologies and techniques for locating clandestine gravesites. The objectives of this study were twofold: 1) determine whether soils exposed to cadaveric decomposition can be visually distinguished from one another via macroscopic and microscopic observation and 2) observe general changes in nutrient and toxic element bioavailability and changes in carbon and nitrogen isotope ratios over time as well as spatially across a body. Visual analyses of soil samples, both macro- and microscopically did not show potential in distinguishing soil exposed to cadaver decomposition from unexposed soil. Relative bioavailability as well as overall bioavailable concentrations of both plant nutrients and toxins were highly elevated after 12 months. Toxins, such as As and Pb, tended to have greater bioavailable concentrations at the near-torso positions, though no consistent spatial trends between nutrient bioavailable concentrations were observed between the three individuals. Nitrogen concentrations and nitrogen isotope (δ15N) ratios show strong potential as markers of clandestine graves throughout the study period. While this research demonstrates further need to uncover what factors influence bioavailability of elements in gravesoil, it shows that the bioavailability of plant nutrients and toxins as well as δ15N ratios are greatly affected by cadaver decomposition, and emerging technologies in gravesite detection based on plant or soil changes have a solid foundation.

Description
Criminal Justice is a complex subject matter, and not everyone agrees on the way a criminal justice system ought to function. But one feature that is common to virtually all forms of proposed justice systems is that a true justice system treats people ethically. The question, then, is how a justice system can achieve this. This investigation analyzed two ethical theories, Kantianism and Utilitarianism, to determine which one would be better suited for guiding a criminal justice system on how to treat the people involved ethically. This investigation focused on applying the two theories to the U.S. Criminal Justice System in particular.
Kantianism is a duty-based moral theory in which actions have an intrinsic moral worth. This means certain actions are morally right and other are morally wrong, regardless of the intended or realized consequences. The theory relies on the categorical imperative to judge the morality of certain actions. It states that an action is moral if its maxim can be willed universal law and if it avoids treating people as merely a means. In contrast, Utilitarianism is a consequentialist theory which focuses on the consequences of an action in judging moral worth. In Utilitarianism, the morally correct action is the one which will maximize utility; that is to say, the morally right action is the one which will produce the greatest amount of happiness and minimize the amount of pain for the greatest number of people.
After applying these two theories to moral dilemmas facing the U.S. Criminal Justice System, including the appropriate collection of DNA evidence, the use of police deception, and the use of criminal punishments such as solitary confinement or the death penalty, it was clear that Kantianism was the ethical theory best suited for guiding the system in treating people ethically. This is because Kantianism’s focus on the intrinsic moral worth of an action rather than its consequences leaves less room for ambiguity than does Utilitarianism.

Description
Calcium is the only ion capable of triggering electrical and chemical reactions in cells which are part of essential biomolecular processes, such as gene transcription and ion flux. Calcium homeostasis, the control of concentration levels, is therefore crucial for the proper functioning of cells. For example, cardiomyocytes, the cells that form cardiac muscle, rely on calcium transfer process to produce muscle contraction.
The purpose of this work is to study aspects of calcium homeostasis in the model organism Saccharomyces cerevisiae, common yeast. Using luminometric techniques, the response of the yeast was monitored against a set of changes in the environment calcium abundance. The results indicate a complex response as both increase and decreases of external calcium induce elevations in cytosolic calcium concentrations.
Calcium is transferred across compartments by means of channels. In Saccharomyces cerevisiae, many of them have been identified; Cch1p-Mid1p, Vcx1p, Pmc1p, Pmr1p, and Yvc1p. Their participation in calcium homeostasis is well established. Observations of cytosolic calcium increase after a hypertonic shock are mainly associated with influx of ions from the environment though the Cch1p-Mid1p. This process is generally considered as driven by calcium concentration gradients. However, recent studies have suggested that the plasma membrane channel, Cch1p-Mid1p, may possess more sophisticated regulation and sensory mechanisms. The results of our experiments support these ideas.
We carried out experiments that subjected yeast to multiple shocks: a hypertonic shock followed by either a second hypertonic shock, a hypotonic shock, or a yeast dilution pulse where the solution volume increases by the calcium concentration has only a small change. The cytosolic calcium concentration of a yeast population was monitored via luminometry.
The main result of this study is the observation of an unexpected response to the combination of hypertonic and hypotonic shocks. In this case it was observed that the cytosolic calcium concentration increased after both shocks. This indicates that cytosolic calcium increases are not solely driven by the presence of concentration gradients. The response after the hypotonic pulse arises from more complex mechanisms that may include sensor activity at the membrane channels and the release of calcium from internal storages.
