The Preservation of the Colonial Spanish Horse and Robert E. Brislawn, Sr.

The Preservation of the Colonial Spanish Horse and Robert E. Brislawn, Sr. In 1493, the Spanish horse importation to the Caribbean islands provided an important stimulus to American exploration as an agent of transportation. In the late nineteenth century, the necessity of horses declined with the advent of railroads and motorized vehicles. Reduction of Native American populations through wars, disease, and forfeiture of territory also contributed to less reliance on horses. Born in 1890, Robert E. Brislawn, Sr., a dedicated horseman, decided to collect and preserve the best Spanish-type horses that he could locate as links to western heritage. From 1924 until his death in 1979, Brislawn’s diligent quest introduced him to like-minded individuals with similar goals. His story places these horses into the larger frames of western, Borderlands, and Spanish Colonial history and their role in the evolving environmental management of the mid-west and western plains and concludes with their development as a heritage breed. Brislawn’s narrative, as told to family and friends, combined the traditional Irish immigrant and nineteenth-century western expansion stories that provided him the opportunity to become familiar with the Spanish-type horses. This background history enabled him to identify horses as a cultural touchstone in a rapidly changing world of international wars and western development. The preservation of Spanish horses provides a small, interesting side story to American western and Borderlands history as well as the national preservation and conservation movements

Quantifying error in OSCE standard setting for varying cohort sizes: A resampling approach to measuring assessment quality

Background: The use of the borderline regression method (BRM) is a widely accepted standard setting method for OSCEs. However, it is unclear whether this method is appropriate for use with small cohorts (e.g. specialist post-graduate examinations). Aims and methods: This work uses an innovative application of resampling methods applied to four pre-existing OSCE data sets (number of stations between 17 and 21) from two institutions to investigate how the robustness of the BRM changes as the cohort size varies. Using a variety of metrics, the ‘quality’ of an OSCE is evaluated for cohorts of approximately n=300 down to n=15. Estimates of the standard error in station-level and overall pass marks, R2 coefficient, and Cronbach’s alpha are all calculated as cohort size varies. Results and conclusion: For larger cohorts (n>200), the standard error in the overall pass mark is small (less than 0.5%), and for individual stations is of the order of 1-2%. These errors grow as the sample size reduces, with cohorts of less than 50 candidates showing unacceptably large standard error. Alpha and R2 also become unstable for small cohorts. The resampling methodology is shown to be robust and has the potential to be more widely applied in standard setting and medical assessment quality assurance and research

Attitudes and Experiences of Tourism Operators in Northern Australia toward People with Disabilities

ABSTRACT The last decade has seen an increasing interest in disability, access and tourism. This has culminated in the emergence of a body of work on 'accessible tourism'. Disability and access have been the subject of a great deal of government regulation and coordination through building codes, awareness training and, through state-based tourism marketing authorities, and policy engagement. Yet, the supply side perspective of industry responses to this consumer group has been under researched In comparison to decades of the past, tourism operators are now making significant efforts to make their products and services more accessible for people with disability. However, most operators noted that there is still a weak demand from the accessible tourism market and with a low recognition of their existing product offerings

Excited state intramolecular proton transfer in hydroxyanthraquinones: Toward predicting fading of organic red colorants in art.

Compositionally similar organic red colorants in the anthraquinone family, whose photodegradation can cause irreversible color and stability changes, have long been used in works of art. Different organic reds, and their multiple chromophores, suffer degradation disparately. Understanding the details of these molecules' degradation therefore provides a window into their behavior in works of art and may assist the development of improved conservation methods. According to one proposed model of photodegradation dynamics, intramolecular proton transfer provides a kinetically favored decay pathway in some photoexcited chromophores, preventing degradation-promoting electron transfer (ET). To further test this model, we measured excited state lifetimes of substituted gas-phase anthraquinones using high-level theory to explain the experimental results. The data show a general structural trend: Anthraquinones with 1,4-OH substitution are long-lived and prone to damaging ET, while excited state intramolecular proton transfers promote efficient quenching for hydroxyanthraquinones that lack this motif

Scintigraphic assessment of bone status at one year following hip resurfacing : comparison of two surgical approaches using SPECT-CT scan

Objectives: To study the vascularity and bone metabolism of the femoral head/neck following hip resurfacing arthroplasty, and to use these results to compare the posterior and the trochanteric-flip approaches. Methods: In our previous work, we reported changes to intra-operative blood flow during hip resurfacing arthroplasty comparing two surgical approaches. In this study, we report the vascularity and the metabolic bone function in the proximal femur in these same patients at one year after the surgery. Vascularity and bone function was assessed using scintigraphic techniques. Of the 13 patients who agreed to take part, eight had their arthroplasty through a posterior approach and five through a trochanteric-flip approach. Results: One year after surgery, we found no difference in the vascularity (vascular phase) and metabolic bone function (delayed phase) at the junction of the femoral head/neck between the two groups of patients. Higher radiopharmaceutical uptake was found in the region of the greater trochanter in the trochanteric-flip group, related to the healing osteotomy. Conclusions: Our findings using scintigraphic techniques suggest that the greater intra-operative reduction in blood flow to the junction of the femoral head/neck, which is seen with the posterior approach compared with trochanteric flip, does not result in any difference in vascularity or metabolic bone function one year after surgery
