Item Bone mass, estimated strength and Kinetic changes in collegiate and post-collegiate runners with a history of stress fracture.(2009-08) Popp, Kristin LynnPurpose: To determine differences in bone geometry, estimates of bone strength, muscle size, bone strength relative to load, and running kinetics, in female runners with and without a history of stress fractures. Methods: A total of 32 competitive distance runners aged 18-35, with (SFX, n = 16) or without (NSFX, n = 16) a history of stress fracture were recruited for this cross-sectional study. Peripheral Quantitative Computed Tomography (pQCT, Orthometrix XCT 2000) was used to assess volumetric bone mineral density (vBMD, mm3), bone area (ToA, mm2), and estimated compressive bone strength (bone strength index; BSI= ToA * ToD2) at the distal tibia (4%). Total (ToA, mm2) and cortical (CoA, mm2= ToA * ToD2) bone area, cortical vBMD, and estimated bending strength (strength strain index; SSIp, mm³) were measured at the 15%, 25%, 33%, 45%, 50% and 66% sites. Participants completed a fatigue run on an instrumented treadmill. GRF's were assessed throughout the run and used in conjunction with pQCT measurements to estimate bone strength relative (cm2) to load at all cortical sites (15%-55%). Results: Bone strength was significantly lower in the SFX group at the mid-upper (45-66% sites) tibia for SSIp (-7-10%). Differences in strength were due to smaller cortical bone area (-6-7%) while total bone area and vBMD were not different at any site. The SFX group also had lower bone strength relative to GRF at the 45% (-12%), 50% (-17%) and 66% (-11%) sites. Peak vertical (Z) GRF's in the SFX group were approximately 5% higher on both legs compared to the NSFX group. Peak breaking force also tended to be higher (0.5%-3.8%) in the SFX group. Propulsion forces were 8-14% in the SFX group compared to the NSFX group, while peak lateral forces were 14.9-32.5% higher. Conclusion: These findings suggest that bone CoA and strength are lower in the middle 1/3 of the tibia in runners with a history of stress fracture. Bone strength relative to load was also lower in this same region suggesting that strength deficits in the middle 1/3 of the tibia indicate higher stress fracture risk. Additionally, our trends indicate that there are several kinetic variables that may be important in predicting stress fracture risk. However, further research is needed to confirm these findings.Item Hypoactive Sexual Desire(2009-05-06) Thomes, Jessica A.This Patient Education Tool addresses the symptoms, diagnosis and treatment for hypoactive sexual desire while raising awareness of patients to its commonality. Hopefully, this patient education tool will demonstrate to patients that there are alternatives to medications and that they should seek counsel in their doctor if they are having any type of concern about their sexual situation.Item Reconsidering the case of María de Zayas: readings through the optic of the monstrous(2014-01) Sanan-Estudillo, Alyssa RobynMaria de Zayas' status as a writer has been, for the longest time, a cold case. Only recently disinterred from history, literary critics have swarmed her textual body and have developed a bewildering array of leads for critical readings of her work. Is Zayas a protofeminist and social reformer, or rather are her views profoundly conservative and status quo? Is the sexualized violence in her work a deliberate and subversive technique, or just a way to cash in? Does she use her baroque sensibilities for particular ends, or does she merely use the prevailing norms? It appears that the recent academic criticism of Zayas has sought to pigeonhole her into one of these categories; these ideas will be further developed in chapter one of this study. Yet it is important for a reader to abandon these extreme views, and, instead of choosing one side or another, to challenge the binary thinking often underlying these questions. I see using the optic of the monstrous as a useful and distinctive tool to view the work of Zayas, especially considering the fact that Zayas herself has employed monstrosity to challenge common assumptions in her own day.
