Description
The purpose of the present study was to investigate seasonal changes in cell proliferation in the brains of adult American bullfrog. Our main question was whether there are seasonal differences in the proliferation and/or differentiation of newborn brain cells into arginine vasotocin- (AVT) or gonadotropin releasing hormone- (GnRH) producing neurons that might regulate bullfrog reproduction. . Bullfrogs in four distinct seasonal groups received injections of bromodeoxyuridine (BrdU), a thymidine analog that is taken up by dividing cells, and then euthanized six weeks later. Using doubleimmunofluorescence procedures to visualize BrdU and AVT or GnRH, we found no evidence for newborn AVT- or GnRH-ergic cells, but observed newborn cells in close proximity to AVT and GnRH cells. My project was a follow-up study to explore seasonal changes in adult cytogenesis related to AVT and GnRH terminal fields. GnRH fiber density fluctuated seasonally in the rostral pre-optic area (RPOA) and lateral septum (LS), and newborn cell numbers changed seasonally in the amygdala (AM) and RPOA. Seasonal differences in plasma testosterone concentrations were negatively related to GnRH fiber density in the LS. These results reinforce the seasonality of reproductive signaling and adult cytogenesis and support a role for seasonal steroid-peptide hormone interactions in modulating GnRH levels. Our results suggest a relationship between seasonal adult cytogenesis and reproduction, and set the stage for further research into the nature of this relationship.

Description
Division of labor among task specialists is a key feature of the organization of insect societies. Foraging and emigration are two distinct colony tasks that nonetheless depend on very similar behaviors, including searching outside the nest, evaluating discoveries, and recruiting nestmates. These subtasks are crucial to collective decisions about forager allocation and nest site selection. It remains unclear, however, whether the same ants are responsible for similar behavior in both contexts, and to what degree they show finer specializations among common subtasks. We are investigating these issues in the ant Temnothorax rugatulus, by making detailed behavioral descriptions of individually marked colonies as they forage and emigrate. There exists considerable heterogeneity among nest-movers, with a small proportion consistently responsible for a large share of recruitment. We found a similar pattern of heterogeneity amongst ants retrieving food during foraging, but had inconclusive results when examining recruitment to the food. It also appears that the ants that complete tasks during foraging are different from the ants that complete similar tasks during emigrations. These findings will shed light on the organization of division of labor and how it contributes to collective decision-making.

Description
The field of biologic research is particularly concerned with understanding nature's complex dynamics. From deducing anatomical structures to studying behavioral patterns, evolutionary theory has developed greatly beyond the simple notions proposed by Charles Darwin. However, because it rarely considers the concept of complexity, modern evolutionary theory retains some descriptive weakness. This project represents an explorative approach for considering complexity and whether it plays an active role in the development of biotic systems. A novel theoretical framework, titled the Genesis Mechanism, was formulated reconsidering the major tenets of evolutionary theory to include complexity as a universal tendency. Within this framework, a phenomenon, referred to as "social transitioning," occurs between higher orders of complexity. Several potential properties of social transitions were proposed and analyzed in order to validate the theoretical concepts proposed within the Genesis Mechanism. The successful results obtained through this project's completion help demonstrate the scientific necessity for understanding complexity from a more fundamental, biologic standpoint.

For more than a decade, Phoenix has spent a considerable amount of time and money on revitalizing its downtown area. The opening of the ASU Downtown campus, the construction of a 20-mile light rail line and the area’s numerous conventions and sporting events all have drawn people to downtown. But the local media have not significantly increased their coverage of the issues that are important to downtown residents — at least not enough to match the growth of the downtown community. The Arizona Republic covers the Valley as a whole, often focusing on the region’s suburbs; The State Press, ASU’s student newspaper, focuses more on the university’s main campus in Tempe; and others like the Phoenix New Times, Phoenix Business Journal and Arizona Capitol Times each have a niche — arts, business and politics — that preclude them from dedicating much coverage to the downtown community. So in 2009, a handful of ASU students started the Downtown Devil, an independent, student-run news website covering the ASU Downtown campus and the surrounding downtown Phoenix community. Over the next few years, the website evolved into a hyperlocal news site for the downtown area, filling a gap in the established local media’s coverage.

The purpose of this research is to gain a deeper understanding of the often-despised financial sector while exploring the parallels it reflects in our society. Information Measurement Theory was applied to several aspects of life apparent in both the financial sector and our society in order to discover parallels present in both. By analyzing the financial sector against our society as a whole, it becomes apparent that the financial sector's composition of individuals reflects that of our societies and is a close representation. Further, the financial sector is able to reflect the importance of information and how individuals react to and justify good and bad results from decision-making. In all our despise of the financial sector is nothing more than the loathe of inherent flaws in our society as a whole.

We discuss processes involved in user-centric security design, including the synthesis of goals based on security and usability tasks. We suggest the usage of implicit security and the facilitation of secureuser actions. We propose a process for evaluating usability flaws by treating them as security threats and adapting traditional HCI methods. We discuss how to correct these flaws once they are discovered. Finally, we discuss the Usable Security Development Model for developing usable secure systems.

Description
The aim of this case study was to help MH, a young adult male with Down syndrome, lose weight and improve his health. Initially he was morbidly obese, suffering from physical, mental, emotional, and health-related side effects. MH and his mother requested help from Dr. Shannon Ringenbach, and resided in Arizona for four months during the process of developing and implementing a program of diet and exercise for him. We created a plan to maximize weight loss in this short period of time. Overall, MH reduced his weight from 276 lbs. to 217 lbs. in four months, his lowest weight being 201 lbs. after he and his mother returned home to Oregon. This is a 75 lb. weight loss and body mass index (BMI) reduction of 13.7 kg/m2. Although to reach a healthy body weight MH would still need to continue his weight loss, this is a significant amount of weight, which is especially difficult for people with Down syndrome to lose. In this case study it was crucial to take into consideration the other aspects that affect weight gain and loss, such as motivation, family life, diet, and lifestyle.

Description
Analytic research on basketball games is growing quickly, specifically in the National Basketball Association. This paper explored the development of this analytic research and discovered that there has been a focus on individual player metrics and a dearth of quantitative team characterizations and evaluations. Consequently, this paper continued the exploratory research of Fewell and Armbruster's "Basketball teams as strategic networks" (2012), which modeled basketball teams as networks and used metrics to characterize team strategy in the NBA's 2010 playoffs. Individual players and outcomes were nodes and passes and actions were the links. This paper used data that was recorded from playoff games of the two 2012 NBA finalists: the Miami Heat and the Oklahoma City Thunder. The same metrics that Fewell and Armbruster used were explained, then calculated using this data. The offensive networks of these two teams during the playoffs were analyzed and interpreted by using other data and qualitative characterization of the teams' strategies; the paper found that the calculated metrics largely matched with our qualitative characterizations of the teams. The validity of the metrics in this paper and Fewell and Armbruster's paper was then discussed, and modeling basketball teams as multiple-order Markov chains rather than as networks was explored.

Description
Background:
Pediatric obesity is associated with lower quality of life (QOL) and populations with high obesity rates, such as Latinos, are especially vulnerable. We examined the effects of a 12-week diabetes prevention program on changes in weight-specific QOL in Latino youth.
Method:
Fifteen obese Latino adolescents (BMI%=96.3±1.1;age=15.0±1.0) completed a 12-week intervention. Youth completed weight-specific QOL measures at baseline, post intervention, and 1-year follow-up. For comparison purposes, intervention youth were matched for age and gender with lean controls.
Results:
At baseline, obese youth exhibited significantly lower weight-specific QOL compared with lean youth (70.8±5.4 to 91.2±2.2, p<0.005). The intervention did not significantly impact weight (90.6±6.8 to 89.9±7.2kg, p=0.44). However, significant increases in weight-specific QOL were observed (70.8±20.9 to 86.2±16.9, p<0.001). Post-intervention QOL scores were no longer significantly different than lean controls (P=0.692). Data from nine youth who returned for follow-up indicated that increases in weight-specific QOL were maintained over time (90.5±4.5 to 85.8±5.9, p=0.74).
Conclusion:
These results indicate that a community-based diabetes prevention program can result in sustained improvements in weight-specific QOL among obese Latino youth. Lifestyle interventions that focus on social interaction and physical activity, rather than weight-loss per se, may help improve the psychosocial health of obese Latino youth.
