The impact on general practitioners of the changing balance of care for elderly people living in institutions

Objectives: To describe utilisation of general practitioners by elderly people resident in communal establishments; to examine variations in general practitioner utilisation and estimate the likely impact of the “downsizing” of long stay provision in NHS hospitals.

Genetic Manipulation of Alcohol Dehydrogenase Levels in Ripening Tomato Fruit Affects the Balance of Some Flavor Aldehydes and Alcohols1

Tomato (Lycopersicon esculentum) plants were transformed with gene constructs containing a tomato alcohol dehydrogenase (ADH) cDNA (ADH 2) coupled in a sense orientation with either the constitutive cauliflower mosaic virus 35S promoter or the fruit-specific tomato polygalacturonase promoter. Ripening fruit from plants transformed with the constitutively expressed transgene(s) had a range of ADH activities; some plants had no detectable activity, whereas others had significantly higher ADH activity, up to twice that of controls. Transformed plants with fruit-specific expression of the transgene(s) also displayed a range of enhanced ADH activities in the ripening fruit, but no suppression was observed. Modified ADH levels in the ripening fruit influenced the balance between some of the aldehydes and the corresponding alcohols associated with flavor production. Hexanol and Z-3-hexenol levels were increased in fruit with increased ADH activity and reduced in fruit with low ADH activity. Concentrations of the respective aldehydes were generally unaltered. The phenotypes of modified fruit ADH activity and volatile abundance were transmitted to second-generation plants in accordance with the patterns of inheritance of the transgenes. In a preliminary taste trial, fruit with elevated ADH activity and higher levels of alcohols were identified as having a more intense “ripe fruit” flavor.

Regulation of herbivore growth by the balance of light and nutrients.

Experiments using planktonic organisms revealed that the balance of radiant energy and available nutrients regulated herbivore growth rates through their effects on abundance and chemical composition of primary producers. Both algae and herbivores were energy limited at low light/nutrient ratios, but both were nutrient limited at high light/nutrient ratios. Herbivore growth increased with increasing light intensity at low values of the light/nutrient ratio due to increases in algal biomass, but growth decreased with increasing light at a high light/nutrient ratio due to decreases in algal quality. Herbivore production therefore was maximal at intermediate levels of the light/nutrient ratio. The results contribute to an understanding of mass transfer mechanisms in ecosystems and illustrate the importance of integration of energy-based and material-based currencies in ecology.

British Balance of Competence Reviews, Part I: ‘Competences about right, so far’. EPIN Working Paper No. 35, October 2013

The first in a series for a CEPS-EPIN project entitled “The British Question and the Search for a Fresh European Narrative” this paper is pegged on an ambitious ongoing exercise by the British government to review all the competences of the European Union. The intention is that this should provide a basis for informed debate before the referendum on the UK remaining in the EU or not, which is scheduled for 2017. This paper summarises the first six reviews, each of which runs to around 80 pages, covering foreign policy, development policy, taxation, the single market, food safety, and public health. The present authors then add their own assessments of these materials. While understandably giving due place to British interests, they are of general European relevance. The substantive conclusions of this first set of reviews are that the competences of the EU are judged by respondents to be ‘about right’ on the whole, which came as a surprise to eurosceptic MPs and the tabloid media. Our own view is that the reviews are objective and impressively researched, and these populist complaints are illustrating the huge gap between the views of informed stakeholders and general public opinion, and therefore also the hazard of subjecting the ‘in or out’ choice for decision by referendum. If the referendum is to endorse the UK’s continuing membership there will have to emerge some fresh popular narratives about the EU. The paper therefore concludes with some thoughts along these lines, both for the UK and the EU as a whole.
