Description
Rainbowfish, Melanotaenia splendida, are a common freshwater species in tropical regions of the world. They are members of the Atheriniformes (Atherinomorpha), the silverside fishes, which are known for some unusual feeding behaviors. Their close relatives, the Cypriniformes, such as mollies, guppies, and mosquitofish, are well studied and exhibit innovative morphologies associated with feeding. The third member of the Atherinomorphs, the Beloniformes, contains the recognizably odd needlefish, halfbeaks, and flying fishes. As a group, it is fair to say that the Atherinomorpha contain some pretty unusual fishes. The purpose of this project was to gain a further understanding of the unique feeding kinematics of Atheriniform fishes using the rainbowfish as an exemplar species. Feeding kinematics were quantified using high speed video recording unrestrained feeding events. Three feeding events from five individuals were analyzed frame by frame, from the time of the mouth opening to mouth closing. The X,Y coordinates of seven specific points were used to calculate the following kinematic variables: cranial elevation, gape distance, premaxillary protrusion, and hyoid depression. The contribution of cranial elevation to the strike was inconsistent. At times the fish raised the head as they expanded the mouth for prey capture, and at other times they did not. Cranial elevation is theoretically important for expanding the head during suction prey capture. Hyoid depression was more consistent, and clearly contributed to expansion of the head elements. Premaxillary protrusion contributed strongly to the event, and the jaws are closed with the premaxilla still protruded, facilitating a ‘nipping’ style jaw closure. A nipping style of prey capture is much like the Cyprinodontiforms, however, in rainbowfish, the event was quicker, and appeared to rely heavily on suction. We used both cleared and stained specimens and CT scans to investigate the underlying morphology of rainbowfish. These images revealed nearly microscopic teeth on the exterior of the jaws, and other features associated with feeding on highly elusive prey (i.e. prey that are mobile and likely to be able to escape predation). Further examination revealed a surprisingly well developed set of pharyngeal jaws, secondary to the oral jaws. The structure of the pharyngeal jaws suggested that most of the prey processing occurred within the pharynx.

Violence in schools occurs throughout America, prevalent to the point of daily happenstance. The epidemic of violence in our society is in sore need of healing efforts. Ending Bullying with Multiple Architectures focuses on the violence of bullying in young children and adolescents, in an effort to mitigate bullying at a critical age, before it transcends into their adult behavior. Bullying begins in elementary schools, a time when our minds are extremely impressionable and our behavioral habits take birth. Bullying may happen for a certain segment of a person's life, but the effects transcend a person's entire life. People who bully may follow a familial cycle of bullying and people who are bullied may become bullies and start a new cycle. With bullying and aggressive behavior increasing exponentially in schools, our society is growing up in a place where it is acceptable to react aggressively to stressful or undesirable situations. Today, violence in our society infiltrates every aspect of our lives, from road rage, to grocery store quarrels, to family ties breaking, to gun violence in school and public spaces. Unplanned acts of violence occur in "spur of the moments". Is our society so impatient, aggressive, antagonistic, individualistic, and isolated because we have been conditioned as human beings to behave this way? Did we miss our chance to work cordially as a community, peacefully and patiently, because we put progress and productivity in front of community and collaboration? How can architecture slow you down, keep you aware of your surroundings and facilitate collaboration and getting along? Why do we accept abrupt anger and violence, and how can architecture create, improve or encourage positive behavioral habits in our impressionable young minds? Ending Bullying with Multiple Architectures translates existing bullying strategies (social architecture) into physical architectural intervention, in an effort to mitigate bullying at the critical age when behavioral habits take birth. This project challenges efficiency based design in order to complement the human experience. By creating healthier spaces that foster wholeness, we can heal violence at this critical age, and thus hopefully reduce future societal violence as a whole.

Description
Civic engagement is often defined as political activism; to be a part of governmental decision making, the practices thereof, and various efforts of participation in voting. However, civic engagement is also known for its role within non-political work, such as community building and development. Because of the former definition many members of our society have a tendency to not embrace the full potential of their community roles. It is always about who is a Republican, who is a Democrat, who looks better, or who has a better name. Now it must be noted that this is not in absolute, not all members of our society work in this thought process, but many still do. If that doesn't come as a surprise to you, then the simplicity of how you can be an engaged member will. As a student attending Arizona State University at the West campus in Phoenix, Arizona, I have chosen to challenge the traditional view of civic engagement and prepare this development plan for the campus community. Having done so, I not only discovered the paths that one can take to be engaged in such matters, but also continued my role as a civil servant.

Abstract Communication scholars have begun to contribute to the theoretical understanding of resilience as a dynamic and collaborative process, which can be talked into being (Buzzanell, 2010). Previous research has examined the role of resilience in romantic couples, however, has focused disproportionately on heterosexual couples. This offers a limited, and singular understanding of how resilience is developed and sustained in romantic relationships. To better understand the scope and breadth of resilience, this study examined five same-sex couples through an in-depth qualitative case study analysis. The purpose of this study was to contribute to the small body of existing data, as well as, enhance our understanding of how resilience works in other contexts. Data was analyzed for thematic patterns, and compared to existing data on same-sex relationships. The findings supported that resilience is a collaborative process that is facilitated by communication. There were some discrepancies from the data collected in this study compared to previous findings; however, due to the small sample size, findings from this study cannot be generalized to the larger population.

Description
In recent years, ecologists have begun to study the effects of urbanization on species diversity. While urban areas generally suffer decreased biodiversity, some species, termed “urban exploiters”, not only live in the city but depend on urban resources to thrive. It is hypothesized that urban exploiters may succeed in part due to phenotypic plasticity, in which organisms rapidly adjust their physiology or behavior to adapt to novel environmental contexts. In the city, it may be adaptive to display thermal plasticity, as the urban heat island effect caused by concrete and asphalt infrastructure prevents cooling at night. In this study, we observed the decorated cricket Gryllodes sigillatus, an invasive urban exploiter found in metropolitan Phoenix, in two separate experiments. We hypothesized that heat tolerance and activity are both plastic traits in this species. In Experiment 1, we predicted that knock-down time, a measure of heat tolerance, would be negatively affected by acclimation to a laboratory environment. Our results suggest that heat tolerance is affected by recent thermal regimes and that laboratory acclimation decreases knock-down time. In Experiment 2, we predicted that activity would increase with temperature until a point of extreme heat, at which point activity would decline. Statistical analysis for the second experiment reveals that activity decreases at 33°C, a natural urban extreme. This suggests either that 33°C is a thermal limit to physiology or that G. sigillatus is able to alter its behavior to exploit local thermal heterogeneity.

Description
As the United States' military presences in Afghanistan and Iraq are being minimized, an increasing number of veterans are transitioning from the military to pursue higher education opportunities. Due to the military's organizational characteristics, socialization procedures, and performance requirements, this population of students likely faces unique barriers to success in traditional models of higher education. The increase of this unique population necessitates research to evaluate their educationally related social and relational needs so that institutions of higher education will be better able to assist in achieving their academic goals. The student-teacher relationship is a key predictor in students' academic success (Yoon, J. S., 2002). Using survey research, this project examines veteran students' perceptions of their relationships with instructors, characteristics of the organization, communication apprehension with professors and peers, and perceived self-esteem. With the assistance of the Pat Tillman Veterans Center at Arizona State University, approximately 3800 veteran students, in both undergraduate and graduate programs, were invited to participate in the research. The study identified significant relationships between a veteran-student's length of time since separating from military service, their feelings of success as a student, self-esteem, and apprehension of communication with professors. There was also a significant relationships on length of military service, self-esteem, and apprehension of communication with professors.

Description
"The Hunger Games: What a Dystopic World Reveals about Modern Society" is an interdisciplinary thesis that examines the impossibility of revolutionary stories or concepts in popular culture by specifically analyzing the Hunger Games project. First, an analysis of what young adult fiction is and how it is written is provided. The formulaic way in which modern adolescent literature is written provides the basic structure for Suzanne Collins' Hunger Games trilogy. The second chapter examines the main character of the Hunger Games series, Katniss Everdeen. The way in which this young female heroine relinquishes her independence and courage due to being consistently undermined by the men and political leaders in her life is traced by following the development of the story throughout the three novels. The third chapter of the thesis delves into how the entire Hunger Games project of novels and films fits into current popular culture. An analysis of the mass production of the novels, and then turning the books into films, merchandise, and further commercialization of the story is discussed in detail throughout the chapter. Finally, the thesis discusses the responsibility authors of young adult literature should assume when addressing a young impressionable audience and how Collins took advantage of the position she had in telling the story of Katniss Everdeen.

As millennials are growing and becoming the "the next big consumer market," understanding them is crucial (Paul, 2001; Kumar & Lim, 2008). This study will attempt to understand their processing of ads by observing the relationship between construal level theory and product type (i.e. hedonic vs. utilitarian). Construal Level theory suggests that individuals construe information at different abstract levels. High levels are characterized by abstract and general representation (e.g. thinking of moving as starting a new chapter of life) while low levels are characterized as including more concrete and contextual details (e.g. thinking of moving as packing boxes). Neither interaction nor main effect of product type was observed either as main effect or as interaction with construal level. However, a significant main effect of construal level was found showing that concrete and contextual (low construal level) information on advertisements makes them more effective and useful to millennials; influences purchase intentions more than ads construed in high construal levels; and, makes brands seem more credible, stable and truthful.

Description
This project examines the secretive world of the Venture Capital Industry specifically focusing on the ideology of gender inequality. Through research it has been found that females within the industry at the partnership level have actually decreased. By completing a literature review, we found that there were several biases and stereotypes that are prevalent within the industry and could be contributing factors for the decreasing participation. Following our literature review, we focused on a sample of 100 from the LPJ Index, and gathered data on all individuals listed, those at the partnership level and all other individuals within the industry. Through analyzing our data we found that female participation at the partner level is low and more importantly that 68% of firms do not even have a female partner in their ranks. We found that male and female partners have relatively the same education and the same areas of interest, which should suggest that they are on the same playing field, which is clearly not represented in the partnership composition, where males are dominating the industry. These findings lend credence to some of the deep rooted stereotypes that are facing females in the Venture Capital Industry and could explain why there are not many opportunities for them. Through future research and participation from firms to actively help increase the opportunities for women, the gender inequality that is facing the Venture Capital Industry can begin to narrow.

Description
This thesis aims to explain how a child can deal with loss through a children's book that I have written and illustrated. The goal is to have a child, as young as the age of seven, be able to pick up the book and come away with an initial understanding of how grief affects people. There are references to other works of literature similarly dealing with the above topic. The different stages of grief are examined, as well as the ways in which grief can be handled. Facial expressions and body language are crucial to understanding others' pain and grief, so this thesis delves into how to translate different expressions and actions, and how artwork and illustrations can portray these same ideas. The story from the book is interwoven throughout the thesis, so as to show my reasoning for each section of the text. Finally, there is a full analysis of the text as well as the illustrations that explains why the text is fitting for each section of the story.
