    American healthcare is costing more, and patients are living with more complex chronic conditions. For many, alternative therapies such as trained service dogs provide a valuable complement to standard treatments. Many providers are unaware of the role a service dog can play in healthcare outside of visual impairment, as well as contraindications and concerns their use may bring. The use of service dogs is still considered by some to be complementary and alternative medicine (CAM) since it is not a part of usual medical practice and is not commonly taught within conventional medical education. The purpose of this project was to test the feasibility of a newly designed provider-centric evidence-based guide to assist providers in determining which disabled patients would be appropriate candidates for service dog therapy in an outpatient setting. The Service Dog Assessment guide (SDAG) was found to be a quick assessment guide, able to be filled out in under 3 minutes. It gave providers helpful information for decision making and patient teaching regarding appropriateness for service dog therapy. Patients responded well to the assessment process

    Female Workplace Self-Help Books: Guiding Women to Become Leaders

    Get PDF
    An emergence of top successful women has developed within the workforce, and more are expected to join that group as time continues (Eagly and Carli, 2003; Sklaroff, 2007). This push to the top has encouraged women to turn to self-help books to gain knowledge and insight on moving up and becoming a leader. Dozens of these books claim to provide the help women need to advance in their workplaces. How can potential readers choose the book most appropriate for their needs? This thesis examines two types of self-help books (Bergsma, 2008) -- problem-focused and growth-oriented -- and how these books are influencing women to be leaders. It analyzes two female workplace self-help books through the method of discourse analysis. The problem-focused text is represented through Gail Evans’ (2000) Play Like a Man, Win Like a Woman: What Men Know About Success that Women Need to Learn. The second type, growth-oriented, is represented through Kelly Cutrone’s (2010) If You Have to Cry, Go Outside and Other Things Your Mother Never Told You. The analysis reveals self-confidence and a strong sense of identity are at the core of the messages of both books

    Controlling the Cycloreversion Reaction of a Diarylethene Derivative Using Sequential Two-Photon Excitation

    Diarylethenes (DAE) are a class of photochromic molecular switches that convert between two structural isomers upon excitation with light. A great deal of research has been dedicated to elucidating the mechanisms of the reversible electrocyclic reactions to make optical memory devices with DAE compounds, but details of the fundamental reaction mechanism after one- or two-photons of light is still lacking. The primary DAE discussed in this dissertation is 1,2-bis(2,4-dimethyl-5-phenyl-3-thienyl)perfluorocyclopentene (DMPT-PFCP), which is a model compound for studying the fundamental reaction dynamics using one- and two-photon excitation experiments. Pump-probe spectroscopy was used to study the low one-photon quantum yield cycloreversion reaction of DMPT-PFCP by changing the excitation wavelength, solvent, and temperature to describe the dynamics on the ground- and excited states. However, the primary goal of this work was to use sequential two-photon excitation with fs laser pulses to map out the cycloreversion reaction dynamics for DMPT-PFCP compound on the first and higher excited states. The cycloreversion quantum yield was selectively increased using sequential two-photon excitation, where after promotion to the S1 state, a second excitation pulse promotes the molecules to an even higher excited state. The mechanism of increasing the yield by promoting the molecules to a higher excited state was explored using pump-repump-probe (PReP) spectroscopy. The PReP experiments follow the excited-state dynamics as the molecules sample different regions of the S1 potential energy surface. The projection of the S1 dynamics onto the higher excited states showed that by changing the secondary excitation wavelength and the delay between excitation pulses, the cycloreversion quantum yield was selectively controlled. Future studies to obtain the specific modes involved in the ring-opening reaction coordinate on the excited-state would further improve our knowledge of the cycloreversion reaction and therefore improve the efficiency of the sequential two-photon excitation process to make very efficient optical memory devices using DAE compounds

    Composition, Structure And Development Of The Crystalline Cone Of The Superposition Compound Eye

    Get PDF
    The crystalline cone of beetles and moths is a transparent, solid structure consisting of a small number of concentrated, hydrophobic proteins. Among these polypeptides is a 67kD protein family which are found in the cones of all 9 species examined. In addition, beetle lenses contain a 125kD polypeptide that is immunologically related to a moth 100kD lens polypeptide. The high molecular weight polypeptides may also be related to the 67kD family because (i) antibodies raised against the beetle 67kD polypeptide cross-react with the moth 67kD and 100kD polypeptides, and with the beetle 125kD polypeptide, (ii) enzyme digests of 67kD and 100kD moth polypeptides yield a number of products of identical mass, and (iii) the purified 67 and 100kD polypeptides dissociate into subunits of similar molecular weight.;The profiles of crystalline cone proteins in lepidopterans and beetles may result from the cone being formed differently. In Calpodes, the proteins are synthesized and deposited in a coordinate manner in the pupa; the cone is nearly complete at adult emergence. In Onitis, the proteins are synthesized and deposited in a temporal manner; the cone is only 70% complete at adult emergence. In both species, the crystalline cone grows by deposition of granules of proteins onto a specialized region of cone cell surface (the plasma membrane template). Subsequent growth in Calpodes involves the appearance of a sponge-like scaffold which becomes packed with protein. In Onitis, newly synthesized protein fuses uniformly around the cone axis, giving rise to cross-sectional profiles which are at first starlike, then square, and finally circular.;A template membrane connecting the four cone cells is the initial site for the ordered deposition of cone protein. The structure of this template defines the limits and volume of the cone. Cone proteins will not fuse with other regions of the plasma membrane, and in the template\u27s absence form random aggregates. A template membrane fraction can be obtained from Calpodes by a two-step urea solubilization which leaves the template intact. It is associated with one 67kD isoform and with the 100kD polypeptide

    In the late 1930\u27s, L. S. Minckler established eight planting experiments on abandoned fields in the vicinity of Norris Lake. These plantings included 700 plots with 11 hardwoods and 3 conifers on 167 acres. In 1968 G. W. Smalley evaluated the condition of the 30-year-old plantations and initiated a growth and yield study of shortleaf pine (Pinus echinata Mill.), eastern white pine (P. strobus L.), and yellow-poplar (Liriodendron tulipifera L.). This study included 66 plots on three soil parent materials (limestone, dolomite and shale) and two aspects (north and south). In the early 1970\u27s, all of the shortleaf pine and six of the white pine plots were destroyed by southern pine bark beetles (Dendroctonus frontalis Z.). The remaining white pine plots and the yellow-poplar plots were remeasured at plantation age 46. The diameter at breast height (dbh) and total height were measured on each of the plots to estimate per acre number of stems, basal area, total cubic-foot volume, merchantable cubic-foot volume, mean dbh and average height of dominants and codominants at each measurement age. These estimates were analyzed by parent material and aspect for each of the three species. At plantation age 30, shortleaf pine height growth was less on shale soils than on dolomite and limestone, though stand volume was not affected by parent material. Mortality of white pine at plantation age 30 was highest on shale soils and northern slopes, though stand volume was not affected by either variable. At plantation age 46 white pine yield was best on dolomitic northern slopes and poorest on dolomitic southern slopes. Growth of yellow-poplar was best on shale soils and poorest on dolomitic sites; aspect did not significantly effect any stand attributes. White pine had the greatest mean volumes of the three species and yellow-poplar had the least. Total cubic-foot yield and yield to a 4-inch top (outside bark) were predicted for white pine and yellow-poplar from site index, basal area, and age in years from seed. Additionally, a prediction equation for cubic-foot yield to a 3-inch top (outside bark) for white pine was developed and compared to a published equation. The published equation for white pine overpredicted yield at 32 years from seed and underpredicted yield at 48 years from seed. The equation for yellow-poplar total yield was also compared to a published equation. The published equation for yellow-poplar overpredicted yield at 31 years from seed and underestimated yield at 47 years from seed. Stem analysis was conducted on one white pine per plot at 32 years from seed and the height to each whorl was measured on two white pine per plot at 48 years from seed. These data were used to construct site index curves with base age 25 (years from seed) for white pine. Stem analysis was also conducted on one yellow-poplar per plot at 31 years from seed and total height at 47 years from seed was measured on ten trees per plot. These data were used to construct site index curves with base age 25 (years from seed) for yellow-poplar. The curves for white pine and yellow-poplar were compared to published curves which underpredicted heights at ages less than 25 years and overpredicted heights at older ages
