Conversation analysis of veterinarians' proposals for long-term dietary change in companion animal practice in Ontario, Canada

Nutritional changes recommended by veterinarians to clients can have a major role in animal-patient health. Although there is literature on best practices that can inform veterinary communication training, little is known specifically about how veterinarians communicate their recommendations to clients in real-life interactions. This study used the qualitative research method of conversation analysis to investigate the form and content of veterinarian-initiated proposals for long-term dietary change in canine and feline patients to further inform veterinary communication training. We analyzed the characteristics and design of veterinarian-initiated proposals for long-term nutritional modification as well as the appointment phases during which they occurred, in a subsample of 42 videotaped segments drawn from 35 companion animal appointments in eastern Ontario, Canada. Analyses indicated that veterinarians initiated proposals at various points during the consultations rather than as a predictable part of treatment planning at the end. While some proposals were worded strongly (e.g., “She should be on…”), most proposals avoided the presumption that dietary change would inevitably occur. Such proposals described dietary items as options (e.g., “There are also special diets…”) or used mitigating language (e.g., “you may want to try…”). These findings seem to reflect delicate veterinarian–client dynamics associated with dietary advice-giving in veterinary medicine that can impact adherence and limit shared decision-making. Our analyses offer guidance for communication training in veterinary education related to dietary treatment decision-making

California Extremely Large Telescope: Conceptual Design for a Thirty-Meter Telescope

Following great success in the creation of the Keck Observatory, scientists at the California Institute of Technology and the University of California have begun to explore the scientific and technical prospects for a much larger telescope. The Keck telescopes will remain the largest telescopes in the world for a number of years, with many decades of forefront research ahead after that. Though these telescopes have produced dramatic discoveries, it is already clear that even larger telescopes must be built if we are to address some of the most profound questions about our universe. The time required to build a larger telescope is approximately ten years, and the California community is presently well-positioned to begin its design and construction. The same scientists who conceived, led the design, and guided the construction of the Keck Observatory have been intensely engaged in a study of the prospects for an extremely large telescope. Building on our experience with the Keck Observatory, we have concluded that the large telescope is feasible and is within the bounds set by present-day technology. Our reference telescope has a diameter of 30 meters, the largest size we believe can be built with acceptable risk. The project is currently designated the California Extremely Large Telescope (CELT)

Radiative and chemical response to interactive stratospheric sulfate aerosols in fully coupled CESM1(WACCM)

We present new insights into the evolution and interactions of stratospheric aerosol using an updated version of the Whole Atmosphere Community Climate Model (WACCM). Improved horizontal resolution, dynamics, and chemistry now produce an internally generated quasi-biennial oscillation and significant improvements to stratospheric temperatures and ozone compared to observations. We present a validation of WACCM column ozone and climate calculations against observations. The prognostic treatment of stratospheric sulfate aerosols accurately represents the evolution of stratospheric aerosol optical depth and perturbations to solar and longwave radiation following the June 1991 eruption of Mount Pinatubo. We confirm the inclusion of interactive OH chemistry as an important factor in the formation and initial distribution of aerosol following large inputs of sulfur dioxide (SO2) to the stratosphere. We calculate that depletion of OH levels within the dense SO2 cloud in the first weeks following the Pinatubo eruption significantly prolonged the average initial e-folding decay time for SO2 oxidation to 47 days. Previous observational and model studies showing a 30 day decay time have not accounted for the large (30–55%) losses of SO2 on ash and ice within 7–9 days posteruption and have not correctly accounted for OH depletion. We examine the variability of aerosol evolution in free-running climate simulations due to meteorology, with comparison to simulations nudged with specified dynamics. We assess calculated impacts of volcanic aerosols on ozone loss with comparisons to observations. The completeness of the chemistry, dynamics, and aerosol microphysics in WACCM qualify it for studies of stratospheric sulfate aerosol geoengineering

Conversation Analysis of Clients’ Active Resistance to Veterinarians’ Proposals for Long-Term Dietary Change in Companion Animal Practice in Ontario, Canada

The impact of nutrition on animal health requires effective diet-related treatment recommendations in veterinary medicine. Despite low reported rates of veterinary clients’ adherence with dietary recommendations, little is known about how clients’ resistance to nutritional proposals is managed in the talk of veterinary consultations. This conversation-analytic study investigated clients’ active resistance to veterinarians’ proposals for long-term changes to cats’ and dogs’ diets in 23 segments from 21 videotaped appointments in Ontario, Canada. Clients’ accounts suggested the proposals themselves or nutritional modifications were unnecessary, inappropriate, or unfeasible, most often based on patients’ food preferences, multi-pet feeding issues, current use of equivalent strategies, or current enactment of the proposed changes. Resistance arose when veterinarians constructed proposals without first gathering relevant diet- and patient-related information, soliciting clients’ perspectives, or educating them about the benefits of recommended changes. Veterinarians subsequently accommodated clients’ concerns more often when resistance involved patient- or client-related issues rather than clients’ lack of medical knowledge. The design of subsequent proposals accepted by clients frequently replaced dietary changes in the initial proposals with nutritional or non-nutritional alternatives and oriented to uncertainty about adherence. This study provides evidence-based findings for developing effective communication training and practice guidelines in nutritional assessment and shared decision-making
