The Evidence Base for Developing a Veterinary Business Management Curriculum

<p><strong>Objective: </strong>This paper sets out to highlight the ongoing need for integrated teaching of business skills in the veterinary curriculum.</p><p><strong>Background:</strong> In response to the changing environment of the veterinary profession, it is important to understand the future needs of veterinary practitioners. While changes to the veterinary curriculum have been made in recent years, they have been highly varied across schools and little evidence is available on how these have improved students’ non-technical skills, knowledge, aptitudes, and attitudes. </p><p><strong>Evidentiary value:</strong> This literature review of 23 papers provides a solid basis for the further development of knowledge on business management issues in veterinary curricula. The impact on practice from our findings is substantial. The role of clinicians in academia is recognised as a primary source of engaging students with business management through their day-to-day teaching. Furthermore, the role of first-opinion vets who take on placement students (known as extra mural studies or ‘EMS’ in the UK) cannot be underestimated as they play an essential role in ensuring that students perceive business skills with the same importance as clinical skills.</p><p><strong>Methods:</strong> This research draws on the findings of 23 papers that emerged as relevant from the structured literature search.  The search yielded 124 papers but many were excluded because they focused on issues beyond the search strategy, did not report empirical findings so were based largely on discussion and conjecture, were not about the undergraduate veterinary curriculum, were not written in English or were not related to business teaching.</p><p><strong>Results: </strong> Employers of recent graduates highly value business skills, and often base their hiring decision on non-technical skills, rather than clinical skills. While changes to the veterinary curriculum have been made to include more non-technical training by individual veterinary schools, it is unclear how effective these programmes have been.</p><p><strong>Conclusion: </strong> Veterinarians have identified a need for greater inclusion of business skills in the veterinary curriculum, however successfully integrating business skills into the curriculum will mean that students learn business principles in non-traditional, non-lecture-style environments with materials inter-twining with clinical teaching. This will mean a significant shift from traditional classroom based delivery of business lectures to an integrated approach. This can only be achieved if business and clinical teaching staff work together in delivering business education to the next generation of veterinarians. That said, the evidence regarding the importance of business within the veterinary medical curriculum, coupled with increasing competition in the market for first-opinion veterinary services, means that changes in the approach to teaching business may be easier to achieve than ever before.</p><p><strong>Application:</strong> The results of this research are applicable to practicing veterinarians in both academic and private practice. It is clear that business management needs to be integrated throughout the veterinary curriculum and thus ‘owned’ by academics with both clinical and non-clinical roles. Veterinarians in private practice also have a critical role to play as these people are the gatekeepers to the real-world experience that placement students encounter. </p><br /> <img src="https://www.veterinaryevidence.org/rcvskmod/icons/oa-icon.jpg" alt="Open Access" /> <img src="https://www.veterinaryevidence.org/rcvskmod/icons/pr-icon.jpg" alt="Peer Reviewed" /

Rapid rotation of a Bose-Einstein condensate in a harmonic plus quartic trap

A two-dimensional rapidly rotating Bose-Einstein condensate in an anharmonic trap with quadratic and quartic radial confinement is studied analytically with the Thomas-Fermi approximation and numerically with the full time-independent Gross-Pitaevskii equation. The quartic trap potential allows the rotation speed $\Omega$ to exceed the radial harmonic frequency $\omega_\perp$. In the regime $\Omega \gtrsim \omega_\perp$, the condensate contains a dense vortex array (approximated as solid-body rotation for the analytical studies). At a critical angular velocity $\Omega_h$, a central hole appears in the condensate. Numerical studies confirm the predicted value of $\Omega_h$, even for interaction parameters that are not in the Thomas-Fermi limit. The behavior is also investigated at larger angular velocities, where the system is expected to undergo a transition to a giant vortex (with pure irrotational flow).Comment: 14 pages, 5 figure

A design assessment of multiwall, metallic stand-off, and RSI reusable thermal protection systems including space shuttle application

The design and assessment of reusable surface insulation (RSI), metallic stand off and multiwall thermal protection systems (TPS) is discussed. Multiwall TPS is described in some detail, and analyses useful for design of multiwall are included. Results indicate that multiwall has the potential to satisfy the TPS design goals better than the other systems. The total mass of the stand-off TPS and of the metallic systems require less primary structure mass than the RSI system, since the nonbuckling skin criteria required for RSI may be removed. Continued development of multiwall TPS is required to verify its potential and to provide the necessary data base for design

The changes in chemical composition during development of the bovine nuchal ligament

Whole bovine nuchal ligaments, or portions thereof (in the case of commercially valuable animals), were obtained from 45 animals (28 fetal and 17 postnatal) ranging in age from 110 days of gestation to 10 yr. Insoluble elastin was quantitatively prepared from the fresh ligaments by extraction with hot alkali and by a combination of multiple extractions with alkaline buffer and then repeated autoclaving. When adult samples were examined, the yields of insoluble residue by these two methods were very similar, but with young fetal samples the second method gave significantly higher values, because of incomplete purification of the elastin residue. The changes in the concentration of collagen, alkali-insoluble elastin, and DNA have been examined. DNA concentration, and, thus, cell population density, fell progressively during the fetal period of development, to reach a steady value soon after birth. Collagen appeared in appreciable quantities before elastin, but its concentration was rapidly halved at about the time of birth. Insoluble elastin concentration was low until the end of the 7th fetal month, at which time it began to rise rapidly. The rate of increase in elastin concentration remained high throughout the next 10–12 wk, by which time the adult value had been reached. Quantitative studies, on the basis of the whole ligament, showed that the total cell content rises to a maximum at birth, but falls soon after to a level about half that at birth. Total collagen production and elastin deposition continue at a steady, maximal rate over the interval from 235 days of gestation to the end of the 1st postnatal month. It is concluded that the immediate postnatal period would be the most favorable phase in which to attempt the isolation of the soluble precursor elastin

Oscillations of a Bose-Einstein condensate rotating in a harmonic plus quartic trap

We study the normal modes of a two-dimensional rotating Bose-Einstein condensate confined in a quadratic plus quartic trap. Hydrodynamic theory and sum rules are used to derive analytical predictions for the collective frequencies in the limit of high angular velocities, $\Omega$, where the vortex lattice produced by the rotation exhibits an annular structure. We predict a class of excitations with frequency $\sqrt{6} \Omega$ in the rotating frame, irrespective of the mode multipolarity $m$, as well as a class of low energy modes with frequency proportional to $|m|/\Omega$. The predictions are in good agreement with results of numerical simulations based on the 2D Gross-Pitaevskii equation. The same analysis is also carried out at even higher angular velocities, where the system enters the giant vortex regime.Comment: 4 pages, 2 figure

Theoretical progress for the associated production of a Higgs boson with heavy quarks at hadron colliders

The production of a Higgs boson in association with a pair of top-antitop or bottom-antibottom quarks plays a very important role at both the Tevatron and the Large Hadron Collider. The theoretical prediction of the corresponding cross sections has been improved by including the complete next-to-leading order QCD corrections. After a brief introduction, we review the results obtained for both the Tevatron and the Large Hadron Collider.Comment: 3 pages, 6 figures, uses svjour.cls. Talk given by L.
