Factorization is not violated

We show that existing proofs of factorization imply the cancellation of certain multiladder contributions that Gotsman, Levin, and Maor had suggested would invalidate the basic factorization theorem in QCD. No modifications of the original argument are necessary, although the details of the example offer useful insight into the mechanisms of factorization.Comment: 11 pages including 10 figure

Delivering social housing: examining the nexus between social housing and democratic planning

The construction of social housing in gentrifying neighbourhoods can ignite contestation, revealing tensions between economic imperatives, social policy and neighbourhood change. With a view to understanding how the convergence of these agendas preserve unpopular, but socially critical housing infrastructure, the aim of this paper is to explore how the challenges social housing implementation encounters across these agendas intersect with a broader agenda for local democratic planning. Using social housing as our empirical focus and directing attention to the gentrifying local government area of Port Phillip in Victoria, Australia, this paper reveals how a council's main asset to support implementation - its policy frameworks - creates an urban narrative of social inclusivity and diversity. Through this case, we illustrate how elected officials and some residents draw from these policies to interject into episodes of community contestation, which we argue presents opportunities to expose and renew commitments to social housing over space and time

The Past and the Future of Veterinary Education, Part Two: A Look to the Future

That we live in an age of fantastic change is a fact which no one will dispute. Equally prominent is the fact that we must change many of our time tested programs and policies in order to survive in our constantly changing scientific environment. This advance makes different demands of different disciplines. It is our purpose to view those that it has and will place on veterinary education and to explore possible solutions that can bring us into our golden era. This age of opportunity is no longer on the horizon - it is here with us waiting and challenging us for acceptance

The Past and the Future of Veterinary Education, Part One: A View of the Past

Although the practice of the veterinary art extends back to the earliest beginnings of civilization, it has only been during comparatively recent times that the education of veterinarians has been conducted along formal lines. The first veterinary school was founded at Lyons, France, in 1761. Following the example set by France, schools of veterinary medicine were soon organized in several other European countries

Female teat size is a reliable indicator of annual breeding success in European badgers: Genetic validation

Assessing which females have bred successfully is a central requirement in many ecological field studies, providing an estimate of the effective female population size. Researchers have applied teat measurements previously to assess whether females, in a variety of mammalian species, have bred; however, this technique has not been validated genetically. Furthermore, several analytical techniques are available to classify individuals, but their misclassification rates have not been compared. We used 22 microsatellite loci to assign maternity, with 95% confidence, within a high-density population of European badgers Meles meles, as plural and subterranean breeding means that maternity cannot be inferred from behavioural observations. The teat lengths and diameters of 136 females, measured May–July 1994–2005, from social groups in which all offspring were assigned a mother, were reliable indicators of recent breeding success. A Generalised Linear Mixed Model (GLMM) classified both breeding and non-breeding females with lower error rates than discriminant analyses and crude teat-size criteria. The GLMM model logit probability = −20 + 1.8 month + 1.6 mean teat length + 1.0 mean teat diameter can be applied quickly in the field to assess the probability with which a female badger should be assigned maternity. This is a low-cost measure which, after validation, could be used in other badger or mammalian populations to assess the breeding success of females. This may be a particularly useful welfare tool for veterinary practitioners, especially during badger culls

Reliable estimation of prediction uncertainty for physico-chemical property models

The predictions of parameteric property models and their uncertainties are sensitive to systematic errors such as inconsistent reference data, parametric model assumptions, or inadequate computational methods. Here, we discuss the calibration of property models in the light of bootstrapping, a sampling method akin to Bayesian inference that can be employed for identifying systematic errors and for reliable estimation of the prediction uncertainty. We apply bootstrapping to assess a linear property model linking the 57Fe Moessbauer isomer shift to the contact electron density at the iron nucleus for a diverse set of 44 molecular iron compounds. The contact electron density is calculated with twelve density functionals across Jacob's ladder (PWLDA, BP86, BLYP, PW91, PBE, M06-L, TPSS, B3LYP, B3PW91, PBE0, M06, TPSSh). We provide systematic-error diagnostics and reliable, locally resolved uncertainties for isomer-shift predictions. Pure and hybrid density functionals yield average prediction uncertainties of 0.06-0.08 mm/s and 0.04-0.05 mm/s, respectively, the latter being close to the average experimental uncertainty of 0.02 mm/s. Furthermore, we show that both model parameters and prediction uncertainty depend significantly on the composition and number of reference data points. Accordingly, we suggest that rankings of density functionals based on performance measures (e.g., the coefficient of correlation, r2, or the root-mean-square error, RMSE) should not be inferred from a single data set. This study presents the first statistically rigorous calibration analysis for theoretical Moessbauer spectroscopy, which is of general applicability for physico-chemical property models and not restricted to isomer-shift predictions. We provide the statistically meaningful reference data set MIS39 and a new calibration of the isomer shift based on the PBE0 functional.Comment: 49 pages, 9 figures, 7 table
