A Picture Worth A Thousand Words: Factors Influencing Disability Accommodations, Alicia E. Martin

Cal Poly Humboldt theses and projects

Because not all disabilities look the same it is difficult to label a person with disabilities just by looking at them. Given that our knowledge, attitudes, and perceptions impact how we interpret our world and our willingness to act, people, including professors, may be biased toward providing accommodations for those with easily recognizable disabilities and biased against those with non-recognizable disabilities, and this may impact the disabled person’s ability to learn. This thesis aims to address whether professors’ disability-related attitudes, perceptions of accommodation reasonableness, and willingness to provide accommodations differ when the disability is recognizable (student is pictured in a …

Cardiometabolic disease (CMD) remains the leading cause of death nationally. Intra-abdominal fat (IAF) is one of the primary risk factors for CMD. Women are particularly vulnerable to developing CMD due to hormonal changes during and after menopause that increase IAF. Excess IAF has deleterious effects on the body, increasing systemic inflammation and oxidative stress, leading to CMD. This systematic review and meta-analyses examined current research related to consumption of whole foods high in anthocyanins, their impact on oxidative stress and inflammation, and the medium and amount of anthocyanin delivery that yields the most benefits to women at risk for CMD. …

Training Postural Control With Eyes Closed Vs. Eyes Open And Effects On Postural Control Improvement, Mark D. Ulbricht

Cal Poly Humboldt theses and projects

Introduction: Ankle sprains are one of the more common injuries in an athletic population. Postural control training can be used in prevention and rehabilitation for ankle sprains. When used preventively postural control training can decrease the risk of sustaining an ankle sprain by 38% (McGuine & Keene, 2006). There are a variety of postural control training programs all emphasizing different aspects of postural control, such as eyes closed, or eyes open situations. Training protocols with either eyes closed or eyes open have been shown to improve both static and dynamic postural control (Zech et al., 2010). The purpose of this …

Assessing Methods For Estimating Biological Sex From Subadult Skeletal Elements, Dorota Zabnicka

Cal Poly Humboldt theses and projects

While methods for estimating the sex of adult skeletons are relatively accurate, these methods are often inconclusive when applied to subadults (non-adults), especially when many secondary sexual characteristics have not fully developed. Furthermore, existing methods for subadults are often tested on samples with relatively homogenous ancestries, calling into question their reliability in more diverse populations. This thesis reviewed techniques for estimating sex in subadult skeletal remains, and the most promising methods were retested on individuals of known sex between ages 3 and 17 years (n=39, 14 males, 25 females) from the Hamann-Todd Osteological Collection. Data collection included measurements of the …
