Description
Dogs' health and wellbeing is of great importance to their owners. The most common nutritional problem for pet dogs is obesity, with 22-40% of pet dogs being classified as overweight or obese. With many adverse health effects associated with obesity, this is a major concern for owners and veterinarians. The degree to which dogs enjoy consuming certain foods can have substantial implications for their body weight, so it is important to understand which aspects of foods make them appealing to dogs. This study aimed to determine whether nutritional aspects of commercial dog foods predict dogs' preferences for those foods. It was found that consumption preference is positively correlated with protein content (p < .001), therefore implying that the protein content of commercial dry dog foods may predict dogs' consumption preferences. Consumption preferences were not predicted by other available measures of food content or caloric value. Dogs' preference for foods high in protein content may be due to the satiating effect of protein. Since foods high in protein both reduce the amount of energy consumed and are found to be palatable to dogs, high-protein dog foods may offer a way for dog food manufacturers, veterinarians, and pet owners to combat obesity in pet dogs.

Description
Students Organize for Syria (SOS) is the student led initiative for Syria. With 18 registered chapters across the United States, this student organization is targeting a multidimensional cause by different means. Though it is now a national movement, it started off with one group at Arizona State University, with one student. Zana Alattar, founder and student director of SOS, tells the story of how she took an ASU organization, Save Our Syrian Freedom (SOS Freedom), to the national level as SOS. As a pre-medical student, she also combines her work in human rights with her future in healthcare. After all, health and human rights have long maintained a synergistic relationship.

Description
Although the number of women earning college degrees and entering the workforce is increasing, a gender gap persists at top leadership positions. Women are faced with numerous challenges throughout the talent pipeline, challenges that often drive women out of the workforce. This paper looks at the power of mentoring and how women, particularly young women, have the potential to overcome these challenges through a successful mentoring relationship. We use examples of successful mentoring programs at the corporate and university level to support the development of a mentoring program at the high school level. Our paper presents the research and development process behind the Young Women in Leadership (YWiL) Workshop, a half-day event that focused on bringing awareness to the importance of mentoring and leadership at the high school level while providing young women with the confidence and knowledge to begin to establish their own mentoring relationships.

Description
‘why we bend' a Bachelor of Fine Arts honors thesis exhibition by Ximenna Hofsetz and Tiernan Warner brings together installation, digital, sculptural, and printed artwork. The main focus concerns memory; and its vague, formless, and hazy nature. The work also examines what would happen if cognitive space could be physically mapped? What would it look like in sculptural form? Memory erodes and distorts with time. We influence our memories as much as they affect us. Thus, just as relationships are ever-changing, and our memories of those we interact with constantly shifting, our relationships with our own memories are malleable and evolve through time. This transient nature of memory is depicted in the various stylistic means of this exhibition by referencing time and space as well as personal memories and ephemera in both concrete and abstract ways. ‘why we bend’ implements a variety of multimedia techniques to examine recollection and its hold on us.

A Guiding Hand: Grief Response in Young Adults works to guide young adults thought the grieving process after the traumatic death of a loved one. It goes through the steps of grieving and what a person can expect when they suddenly lose someone dear. Written from the point of view of someone who had lost their best friend in a murder/suicide, A Guiding Hand, shares a personal view that is often missing in other books on grief. This piece works to prepare other young adults for the unexpected emotions that are associated with grief. It also works to provide coping strategies to help recover from a traumatic loss in a healthy manner and to put people in touch with resources they may not know exist in order to help with healing.

Description
This project explores a variety of ways of framing the problem of obesity, beginning with a multidisciplinary assessment of genetic, environmental, cultural, nutritional, and socioeconomic factors involved in the structure and the consequences of each frame. How obesity is framed as a problem has a profound impact on the kinds of solutions that may be deemed scientifically appropriate. But frames are not entirely evidence-based, inasmuch as political and moral values infuse debates about the nature of obesity. Drawing on interdisciplinary resources from bioethics and the philosophy of science, I strive to offer strategic insight in to how to navigate the complexity of these issues.

ABSTRACT
Environmental and genetic factors influence schizophrenia risk. Individuals who have direct family members with schizophrenia have a much higher incidence. Also, acute stress or life crisis may precede the onset of the disease. This study aims to understand the effects of environment on genes related to schizophrenia risk. It investigates the impact of sleep deprivation as an acute environmental stressor on the expression of Htr2a in mice, a gene that codes for the serotonin 2A receptor (5-HT2AR). HTR2A is associated with schizophrenia risk through genetic association studies and expression is decreased in post-mortem studies of patients with the disease. Furthermore, sleep deprivation as a stressor in human trials has been shown to increase the binding capacity of 5-HT2AR. We hypothesize that sleep deprivation will increase the number of cells expressing Htr2a in the mouse anterior prefrontal cortex when compared to controls. Sleep deprived that mice express EGFP under control of the Htr2a promoter displayed anteroposterior gradients of expression across sagittal sections, with concentrations seen most densely within the prefrontal cortex as well as the anterior pretectal nucleus, thalamic nucleus, as well as the cingulate gyrus. Htr2a-EGFP expression was most densely visualized in cortical layer V and VI pyramidal neurons within the lateral prefrontal cortex of coronal sections. Furthermore, the medial prefrontal cortex contained significantly cells expressing Htr2a¬-EGFP than the lateral prefrontal cortex. Ultimately, the hypothesis was not supported and sleep deprivation did not result in more ¬Htr2a-EGFP expressing cells compared to basal levels. However, expressing cells appeared visibly brighter in sleep-deprived animals when compared to controls, indicating that the amount of intracellular Htr2a-GFP expression may be higher. This study provides strong visual representations of expression gradients following sleep deprivation as an acute stressor and paves the way for future studies regarding 5H-T2AR’s role in schizophrenia.

Description
Obesity is a growing issue in the Western world, as well as other international countries. This is leading to increases in complications associated with obesity. One such complication is osteoarthritis (OA) of load bearing joints that requires surgical treatment by total knee arthroplasty (TKA). Obesity is also associated with an increase in surgical complications that may lead to poor TKA outcomes. Additionally, the female gender is also known to be associated with increased rates of severe, clinical OA. This study was designed to determine the comparative efficacy of two knee implants in the obese female population through retrospective chart review and data analysis. The implants differ in their level of constraint, with the total stabilizing (TS) being more constrained than the posterior stabilizing (PS). We hypothesized that the TS implants would be associated with improved functional outcomes in the obese female population. The TS implant was observed to be associated with earlier improvement of both passive and active range of motion. This implant also showed greater improvement from pre-operative condition in stability, rejecting our null hypothesis and supporting our hypothesis.

Description
There has been an alarming rise in the prevalence of obesity which has been attributed to the paralleled rise in consumption of high-fat foods. It’s commonly accepted that high-fat diets can lead to increased weight gain, however not all fats have the same physiological action. This study primarily focuses on the effect of canola oil, a monounsaturated fat, on energy homeostasis and body composition when it’s given as a supplement to a high-fat diet composed of saturated fatty acid. Rodent models were divided into three dietary groups: 1) low-fat diet (LFD), 2) high-fat diet (HFD) and 3) canola oils supplemented HFD (HF+CAN). After 4 weeks of dietary intervention, samples of epididymal fat, perinephric fat, and liver were analyzed across the three groups to see if the changes in energy homeostasis could be explained by the cellular behavior and composition of these tissues. Interestingly, the supplement of canola oil appeared to reverse the deleterious effects of a saturated fat diet, reverting energy intake, body weight gain and adipose tissue sizes to that (if not lower than that) of the LFD group. The only exception to this effect was the liver: the livers remained larger and fattier than those of the HFD. This occurrence is possibly due to a decrease in free fatty acid uptake in the adipose tissues—resulting in smaller adipose tissue sizes—and increased fatty acid uptake in the liver. The mechanism by which this occurs has yet to be elucidated and will be the primary focus of upcoming studies on the effect of monounsaturated fat on other diets.
