Description
Dietary self-monitoring has been shown to be a predictor of weight loss success and is a prevalent part of behavioral weight control programs. As more weight loss applications have become available on smartphones, this feasibility study investigated whether the use of a smartphone application, or a smartphone memo feature would improve dietary self-monitoring over the traditional paper-and-pencil method. The study also looked at whether the difference in methods would affect weight loss. Forty-seven adults (BMI 25 to 40 kg/m2) completed an 8-week study focused on tracking the difference in adherence to a self-monitoring protocol and subsequent weight loss. Participants owning iPhones (n=17) used the 'Lose It' application (AP) for diet and exercise tracking and were compared to smartphone participants who recorded dietary intake using a memo (ME) feature (n=15) on their phone and participants using the traditional paper-and-pencil (PA) method (n=15). There was no significant difference in completion rates between groups with an overall completion rate of 85.5%. The overall mean adherence to self-monitoring for the 8-week period was better in the AP group than the PA group (p = .024). No significant difference was found between the AP group and ME group (p = .148), or the ME group and the PA group (p = .457). Weight loss for the 8 week study was significant for all groups (p = .028). There was no significant difference in weight loss between groups. Number of days recorded regardless of group assignment showed a weak correlation to weight loss success (p = .068). Smartphone owners seeking to lose weight should be encouraged by the potential success associated with dietary tracking using a smartphone app as opposed to the traditional paper-and-pencil method.

Description
The most horrific, darkest, and powerful forms of the sublime take place inside the enclosure of the human psyche; the interior of the mind is the playground for the sublime--not the crag and canyon filled natural world. For Immanuel Kant and Edmund Burke, the driving force of the power of the sublime stems from the feelings of pain and fear: where is that more manifested than in the mind? Unlike the common, traditional, and overwhelmed discussion of Percy Shelley and his contemporaries and the power of the sublime in nature, I will argue that in The Cenci, Shelley, through well-chosen diction and precise composition of terrifying images, fashions characters and scenes in an emotion-driven play that elevates the mind of the reader to a transcendent sublime experience. Through a discussion of the theories of the aesthetic of the sublime laid out by Longinus, Burke, and Kant, I will provide a foundation for the later discussion of the rhetorical sublime evoked by Shelley in the ardent and horrifying play that is The Cenci. Looking at the conventional application of the theories of the sublime to romantic writing will make evident the holes in the discussion of the sublime and romantic writings that have almost forgotten the powerful and psychological rhetorical aspect of the sublime that is emphasized in the theoretical writings of both Burke and Kant. To clarify what is traditionally associated with Shelley and the sublime, a brief analysis of the Shelleyean sublime and Shelley's 1816 poem "Mont Blanc" will prepare the reader for an unconventional, but every bit important and powerful, function of the sublime in the 1819 play The Cenci based on the horrific happenings of a historical 16th century Italian noble family.

Description
The gold standard for bone measurement is DXA (dual energy X-ray absorptiometry). Typically, to observe changes in bone by DXA, a minimum of a 4-month intervention is required. Serum osteocalcin (OST) (a bone formation marker) and quantitative ultrasound (QUS) of the calcaneus can be used as indicators of bone change but the sensitivity and time course of these indices to short term interventions are unknown. The purpose of this study was twofold: to compare monthly changes in OST and QUS in response to jump training and to evaluate the relationship between DXA, OST and QUS. Young women with QUS t-scores less than 1.0 were randomized into a jump training (J) (n=16) or control (C) (n=16). J consisted of a progressive routine of 1 and 2-footed jumping performed 3 days per week for 4 months. Body composition, QUS and OST were measured at baseline, and monthly for 4 months. DXA and 24-hour dietary recalls were completed at baseline and 4 months. Low attrition rate (12.5%) and high compliance (98%) with the exercise intervention was recorded. No significant correlations between QUS and OST existed. No significant differences were observed between groups at baseline in body composition or bone variables. Monthly increases in OST were observed but there were no significant differences over time between groups in any bone variables. OST and QUS may be indicative of short term bone changes but these variables were not specifically sensitive to the jumping intervention in this population of women.

Description
Nut consumption, specifically almonds, have been shown to help maintain weight and influence disease risk factors in adult populations. Limited studies have been conducted examining the effect of a small dose of almonds on energy intake and body weight. The objective of this study was to determine the influence of pre-meal almond consumption on energy intake and weight in overweight and obese adults. In this study included 21, overweight or obese, participants who were considered healthy or had a controlled disease state. This 8-week parallel arm study, participants were randomized to consume an isocaloric amount of almonds, (1 oz) serving, or two (2 oz) cheese stick serving, 30 minutes before the dinner meal, 5 times per week. Anthropometric measurements including weight, waist circumference, and body fat percentage were recorded at baseline, week 1, 4, and 8. Measurement of energy intake was self-reported for two consecutive days at week 1, 4 and 8 using the ASA24 automated dietary program. The energy intake after 8 weeks of almond consumption was not significantly different when compared to the control group (p=0.965). In addition, body weight was not significantly reduced after 8 weeks of the almond intervention (p=0.562). Other parameters measured in this 8-week trial did not differ between the intervention and the control group. These data presented are underpowered and therefore inconclusive on the effects that 1 oz of almonds, in the diet, 5 per week has on energy intake and bodyweight.

Description
ABSTRACT Epidemiological studies have suggested a link between nut consumption and weight. The possible effects of regular nut consumption as a method of weight loss has shown minimal results with 2-3 servings of nut products per day. This 8 week study sought to investigate the effect of more modest nut consumption (1 oz./day, 5 days/week) on dietary compensation in healthy overweight individuals. Overweight and obese participants (n = 28) were recruited from the local community and were randomly assigned to either almond (NUT) or control (CON) group in this randomized, parallel-arm study. Subjects were instructed to eat their respective foods 30 minutes before the dinner meal. 24 hour diet recalls were completed pre-trial and at study weeks 1, 4 and 8. Self-reported satiety data were completed at study weeks 1, 4, and 8. Attrition was unexpectedly high, with 13 participants completing 24 dietary recall data through study week 8. High attrition limited statistical analyses. Results suggested a lack of effect for time or interaction for satiety data (within groups p = 0.997, between groups p = 0.367). Homogeneity of of inter-correlations could not be tested for 24-hour recall data as there were fewer than 2 nonsingular cell covariance matrices. In conclusion, this study was unable to prove or disprove the effectiveness of almonds to induce dietary compensation.

Description
In the first thirty years of the XX century, an old literary visual tradition was reborn in a series of new striking visual texts better known as calligrams. They were produced by some avant-garde poets such as Vicente Huidobro, José Juan Tablada, Alberto Hidalgo and Carlos Oquendo de Amat in Latin America, and Juan Larrea, Guillermo de Torre, Francisco Vighi, Luis Mosquera, and others in Spain. However, with few exceptions, the interpretation of those written drawings has caught little attention from literary critics. This research, contrasted to that of Willard Bohn's, is a contribution to the deciphering of such literary art form, designated here as the figurative visual poem. It is a proposal for its visual reading which draws from the fact that this type of text is concretely a drawing formed by written verses. As such, it can be regarded as a plastic writing, combining pictorial and verbal signs in one perceptible configuration on the page. The result of this semiotic operation is a hybrid product in which the iconic forms become symbolic and vice versa. It is in fact, an art object which should be approached as a text that can be seen as well as read. The study leads to the conclusion that Willard Bohn misreads the order in which language and image are articulated in the visual poem identified with the second order semiological system proposed by Roland Barthes, placing preeminence on language over image. This results in reading the avant-garde visual figurative poem in an ekphrastic fashion. Consequently, the role of the image in the system is left in an ambiguous realm at the time of deciphering this hybrid text. Our contribution to re-conducting this undertaking has been equally drawn from a semiotic stance taken from Louis Hjemslev that balances language and image as correlates of a semiotic function. Due to the signaling nature of both, language and figure, a visual poem becomes an iconic metaphor as well as a metaphoric icon, and moreover a self-referential sign, thus justifying its status of an autonomous art.

Description
The hagiographic comedy written by Tirso de Molina Los lagos de San Vicente (1607) presents the journey of Santa Casilda in search of the cure of an illness in her blood that affects her. Casilda rejects the medical assistance offered to her by Muslim doctors and miraculously she finds the cure in the Christian world. In this quest, the intellectual and theological evolution of the future saint in defense of the Christian faith is presented. This dissertation will study the resources that Tirso de Molina employs to show the rejection and displacement against the Islamic world represented by a series of erotic behaviors that, in the effort of dramatizing these impertinences they are characterized within a second discourse. Tirso de Molina takes advantage of the hagiographic comedy's discourse nature and the baroque's obscure literary characteristics to express his messages. This dissertation will study in detail how the combination of hagiographic theatrical elements with linguistic expressions are used to convey a subversive discourse that therefore suggests the application of queer theory as a frame of reference. As a result of this investigation it is concluded that Tirso de Molina promotes the hagiographic model and in order to contrast the triumph of the moral Catholic world over the immoral Muslim world the play writer makes references to the nefarious sin.

ABSTRACT This study evaluated the LoseIt Smart Phone app by Fit Now Inc. for nutritional quality among users during an 8 week behavioral modification weight loss protocol. All participants owned smart phones and were cluster randomized to either a control group using paper and pencil record keeping, a memo group using a memo function on their smart phones, or the LoseIt app group which was composed of the participants who owned iPhones. Thirty one participants completed the study protocol: 10 participants from the LoseIt app group, 10 participants from the memo group, and 11 participants from the paper and pencil group. Food records were analyzed using Food Processor by ESHA and the nutritional quality was scored using the Healthy Eating Index - 2005 (HEI-2005). Scores were compared using One-Way ANOVA with no significant changes in any category across all groups. Non-parametric statistics were then used to determine changes between combined memo and paper and pencil groups and the LoseIt app group as the memo and paper and pencil group received live counseling at biweekly intervals and the LoseIt group did not. No significant difference was found in HEI scores across all categories, however a trend was noted for total HEI score with higher scores among the memo and paper and pencil group participants p=0.091. Conclusion, no significant difference was detected between users of the smart phone app LoseIt and memo and paper and pencil groups. More research is needed to determine the impact of in-person counseling versus user feedback provided with the LoseIt smart phone app.

Description
ABSTRACT As referenced in Navajo ceremonial prayers and songs, "Saad bee hahoozhood jini," it began harmoniously with language. This dissertation examines and celebrates in new ways the meaning of language in Navajo literature. The first chapter is an introduction of this dissertation. I share my personal experiences with language, both English and Navajo, and how it has shaped me to be the person I am today as a Navajo speaker, student, educator, and professional. The second chapter contains an analysis and review of Western ideology of feminism and its place in Navajo society and a comparative study of several works written by Navajo authors, including Laura Tohe, Luci Tapahonso, and Nia Francisco, and how their creative works reflect the foundation of Navajo culture, Asdzaa Nadleehe, Changing Woman. The third chapter presents my own short fiction of Navajo characters living in today's society, a society that entails both positive and negative issues of Navajo life. These stories present realistic twenty-first century environments on the Navajo reservation. The fourth chapter consists of a short fiction written originally in the Navajo language. The story also represents the celebration of Navajo language as it thrives in today's time of tribal and cultural struggles. The sense of it being told in Navajo celebrates and preserves Navajo culture and language. The final chapter is the beginning of an oral narrative presented in written form, that of my grandmother's life story. This introduction of her story also is in itself a commemoration of language, oral Navajo language.

Community Supported Agriculture programs (CSAs) have become a viable local source of fresh agricultural goods and represent a potentially new way to improve fruit and vegetable consumption among individuals and families. Studies concerning CSAs have focused mainly on characteristics of the typical CSA member and motivations and barriers to join a CSA program. The purpose of this study was to examine whether behavior and attitudinal differences existed between current CSA members and a nonmember control group. Specifically, ecological attitudes, eating out behaviors, composting frequency, and family participation in food preparation were assessed. This study utilized an online survey comprising items from previous survey research as well as newly created items. A total of 115 CSA member and 233 control survey responses were collected. CSA members were more likely to be older, have more education, and have a higher income than the control group. The majority of CSA members surveyed were female, identified as non-Hispanic and Caucasian, earned a higher income, and reported being the primary food shopper and preparer. The majority of members also noted that the amount and variety of fruits and vegetables they ate and served their family increased as a result of joining a CSA. CSA members were more ecologically minded compared to the control group. Frequency of eating out was not significantly different between groups. However, eating out behaviors were different between income categories. CSA members spent significantly more money at each meal eaten away from home and spent significantly more money on eating out each week. In both cases, controlling for income attenuated differences between groups. CSA members composted at a significantly higher rate and took part in other eco-friendly behaviors more often than the control group. Finally, no significant difference was evident between the two groups when analyzing family involvement in food preparation and meal decision-making. Overall, some significant attitudinal and behavioral differences existed between CSA members and non-CSA members. Further research is necessary to examine other distinctions between the two groups and whether these differences occur as a result of CSA membership.
