Examination of the impact and effectiveness of herd health and welfare assessment in im-proving animal welfare on organic dairy farms, using qualitative interviews.
During winter 2002-03, 15 organic dairy farms in SW England participated in a herd health and welfare assessment and benchmarking study. A second assessment was carried out on 14 of the original 15 farms and on 14 new farms during winter 2003-04. The effectiveness of the herd health and welfare as-sessments and benchmarking in delivering animal health and welfare improvements was investigated by means of qualitative research interviews. The inter-views were conducted between August and November 2004. The average length of interview was one hour and fifteen minutes. Five common themes were iden-tified and headed ‘Sensitivities and misgivings’; ‘Ac-ceptability of scoring methodology and indicators assessed’; ‘Raised awareness and motivation to im-prove’; ‘Veterinary support and herd health planning’ and ‘Value of assessment and benchmarking’. It was apparent that farmers, who took part voluntarily in the study, took the results of the herd health and welfare assessments very seriously and were clearly motivated by the process. The main focus for change was related to housing issues. The main constraints to welfare improvement were a shortage of finance to affect change beyond relatively simple alterations and a lack of information on the identification of changes likely to improve animal welfare in given situations
Combining Ethological Thinking and Epidemiological Knowledge to Enhance the Naturalness of Organic Livestock Systems
Organic livestock farming places strong emphasis on conditions that allow animals to exhibit behavioural needs. This involves the provision of a natural environment and, in particular, outdoor conditions and a reliance on natural forages. Such environments also allow animals to be effectively integrated into crop production. However, there are potential disease risks associated with these conditions, with control options being partly limited by restrictions on chemoprophylactic measures. Examples from dairy and poultry production demonstrate how a basic understanding of ethology and a knowledge of disease epidemiology can enhance the welfare of animals whilst satisfying the ecological objectives of organic farming. Existing epidemiological models and published data can be used to examine the potential ensuing health hazards and control possibilities and to suggest alternatives
The Importance Of Community: Investing In Effective Community-Based Crime Prevention Strategies
After more than a year of listening to our community, researching evidence-based practices, and evaluating our own efforts, 'The Importance of Community' inaugural report unequivocally asserts that our greatest potential of reducing homicides and incarceration as a result of committing a crime is deeply rooted in collective community action and targeted interventions aimed at serving narrowly defined populations. In this report, The Indianapolis Foundation will summarize years of community-based recommendations and provides a specific community investment plan based on multiple community convenings, crime prevention related reports, and listening to our community
Coarse Graining RNA Nanostructures for Molecular Dynamics Simulations
A series of coarse-grained models have been developed for the study of the
molecular dynamics of RNA nanostructures. The models in the series have one to
three beads per nucleotide and include different amounts of detailed structural
information. Such a treatment allows us to reach, for the systems of thousands
of nucleotides, a time scale of microseconds (i.e. by three orders of magnitude
longer than in the full atomistic modelling) and thus to enable simulations of
large RNA polymers in the context of bionanotechnology. We find that the
3-beads-per-nucleotide models, described by a set of just a few universal
parameters, are able to describe different RNA conformations and are comparable
in structural precision to the models where detailed values of the backbone
P-C4' dihedrals taken from a reference structure are included. These findings
are discussed in the context of the RNA conformation classes
The effects of buffer molarity, agitation rate and mesh size on verapamil release from modified release mini-tablets using USP Apparatus 3
The effects of agitation rate, buffer molarity,and mesh size on the dissolution rate of verapamil hydrochloride from sustained release matrix tablets were studied using USP Apparatus 3. Eudragit® and Carbopol® were used as rate-retarding polymers in tablets prepared by wet granulation.The study was conducted to determine whether the drugs exhibit similar release characteristics when tested under the same dissolution conditions. It was found that the dissolution rate of verapamil hydrochloride was affected by the variables assessed in these studies
Stellar Substructures around the Hercules Dwarf Spheroidal Galaxy
We present deep -band DECam stellar photometry of the Hercules Milky Way
satellite galaxy, and its surrounding field, out to a radial distance of 5.4
times the tidal radius. We have identified nine extended stellar substructures
associated with the dwarf; preferentially distributed along the major axis of
the galaxy. Two significant over-densities lie outside the 95\% confidence band
for the likely orbital path of the galaxy and appear to be free-floating tidal
debris. We estimate the luminosity of the new stellar substructures, and find
that approximately the same amount of stellar flux is lying in these extended
structures as inside the main body of Hercules. We also analyse the
distribution of candidate blue-horizontal-branch stars and find agreement with
the alignment of the substructures at a confidence level greater than 98\%. Our
analysis provides a quantitative demonstration that Hercules is a strongly
tidally disrupted system, with noticeable stellar features at least 1.9 kpc
away from the galaxy.Comment: 13 pages, 13 figures, accepted for publication in Ap
Modelling the ability of legumes to suppress weeds
The ability of different legume cover crops to suppress annual weeds during the early establishment phase was compared using a simulation model of inter-plant competition and field observations. Height, partitioning parameters, extinction coefficients, crop density and time of emergence were recorded for 11 species sown in monocultures. A naturally occurring population of fat hen (Chenopodium album) was present on the experiment. The competition model was run to compare the expected suppressive ability of the different species on this weed. Samples of C. album were also taken from each plot immediately prior to cutting to provide some empirical observations. Predicted suppressive ability was correlated with seed size and height with large seeded, tall species such as white sweet clover being the most competitive. However, these species may recover poorly from mowing compromising their potential to suppress perennial weeds and a mixture of contrasting species may provide the optimum weed control
Happiness as stable extraversion : internal consistency reliability and construct validity of the Oxford Happiness Questionnaire among undergraduate students
The Oxford Happiness Questionnaire (OHQ) was developed by Hills and Argyle (2002) to provide a more accessible equivalent measure of the Oxford Happiness Inventory (OHI). The aim of the present study was to examine the internal consistency reliability, and construct validity of this new instrument alongside the Eysenckian dimensional model of personality. The Oxford Happiness Questionnaire was completed by a sample of 131 undergraduate students together with the abbreviated form of the Revised Eysenck Personality Questionnaire. The data demonstrated good internal consistency reliability (alpha = .92) and good construct validity in terms of positive association with extraversion (r = .38 p < .001) and negative association with neuroticism (r = −.57 p < .001). The kind of happiness measured by the OHQ is clearly associated with stable extraversion
