VegeDog: Formalism, vegetarian dogs, and partonomies in transition

The pragmatics of 'vegetarian' and 'carnivorous' exhibits an asymmetry that we put in evidence by analyzing a newspaper report about vegetarian dog-owners imposing a vegetarian diet on their pets. More fundamental is the problem of partonomy versus containment, for which we attempt a naive but formal analysis applied to ingestion and the food chain, an issue we derive from the same text analyzed. Our formal tools belong in commonsense modelling, a domain of artificial intelligence related to extra-linguistic knowledge and pragmatics. We first provide an interpretation of events analyzed, and express it graphically in a semantic-network related representation, and propose an alternative that we express in terms of a modal logic, avoiding the full representational power of Hayes's "ontology for liquids".

On treating the symptoms and not the cause: reflections on the Dangerous Dogs Act

The experience of saving a dog that later turned out to be a Pit Bull and therefore banned under the Dangerous Dogs Act 1991, made me investigate the Act and its implications. The Act is not built on evidence and by compiling results from different studies on dog bites and breed‐specific legislation in different countries the conclusion is that there is not much empirical support for breed bans either. ‘Dangerous breeds’ do not bite more frequently than German Shepherds and directing legislation towards certain breeds deemed as ‘dangerous’ cannot therefore be seen as justified. The strength of the label ‘dangerous dog’ seems to rule out policies that follow the facts and there is more treating of symptoms than causes. [From the Author]

When deterrence works - and when it doesn't: a comparison of Sweden's prostitution law and UK's Dangerous Dogs Act

Many pieces of legislation have been implemented with the anticipation - or justification - that they will have a deterrent effect. Deterrence was clearly argued in the debate preceding the Swedish prostitution law prohibiting the purchase of sexual services, but less so regarding the Dangerous Dogs Act, which was a very rapid response to a particular moral panic. As it turned out, the Swedish law has had a deterrent effect on street prostitution in that 'respectable' buyers were deterred. It will be argued that it is this very 'respectability' that makes deterrence work in this case. Regarding the Dangerous Dogs Act, the owners of Pit Bulls and other banned breeds are not considered 'respectable' and the banning might have had the reversed effect - increasing the attraction of these dogs, rather than deterring the ownership. Apart from deterrence and its consequences, the rendering invisible of key actors - buyers and owners respectively - and the use of symbolic legislation to promote moral messages will also be considered.

Can evidence-based healthy housing interventions be put into practice in the UK's private housing sector?

The UK’s public health agenda has encouraged enhanced housing and health interventions. The private housing sector (privately rented and owner occupied) is the favoured and majority UK tenure, but is it seen as a primarily health promoting environment, or a commercial asset? There has been a growing interest in integrating health and housing policy in recent years. However, housing and public health fall under separate government departments and funding regimes. Partnership working has sought to overcome silo working and encourage evidence-based practice, yet is particularly challenging for interventions in the private housing sector, with an increased emphasis on ‘personal responsibility’ for conditions. Strategic public health frameworks are in place, but barriers remain and there is pressure for organisations to revert to core activities. An accessible, continually updated evidence base specific to private sector housing is recommended, to help estimate health gain arising from interventions to prioritise activities and address inequalities.

Breast milk levels of zinc and omega-6 polyunsaturated fatty acids and growth of healthy Chinese infants

AIM: To examine the concentrations of zinc and omega-6 polyunsaturated fatty acids (omega-6 PUFAs) in breast milk, the impact of zinc on omega-6 PUFA metabolism, and the growth rate of infants. METHODS: Forty-one mother-term infant pairs from a rural area of northern Beijing, China, who were 1 month (n = 18, group I) and 3 months (n = 23, group II) old and exclusively breastfed, were studied. The dietary records and the concentrations of zinc and omega-6 PUFAs in the milk of lactating women and the increase in weight and length of their infants during 1 and 3 postnatal months were analysed. RESULTS: The dietary intakes of mothers in the two groups were the same, i.e. high in carbohydrate and low in fat, protein and energy. The maternal zinc intake was 7.5mg/d and thus reached only 34.6% of the current Recommended Nutrient Intake (RNI). The levels of zinc and arachidonic acid (AA, C20:4 omega-6) in the milk of group I were significantly higher than those in group II. Furthermore, significant positive correlations were found between the concentrations of zinc and AA in the breast milk and between the level of milk AA and weight gain. CONCLUSION: Zinc may be a co-factor and essential for essential fatty acids (EFA) metabolism. Thus suboptimal zinc intake may cause EFA imbalance. Further studies of Chinese rural mother-infant pairs are necessary to determine whether zinc supplementation should be recommended when lactation exceeds 3 months.
