Assessment of evaluations made to healthy eating policies in Europe: a review within the EATWELL Project

Objective: To identify and assess healthy eating policies at national level which have been evaluated in terms of their impact on awareness of healthy eating, food consumption, health outcome or cost/benefit. Design: Review of policy documents and their evaluations when available. Setting: European Member States. Subjects: One hundred and twenty-one policy documents revised, 107 retained. Results: Of the 107 selected interventions, twenty-two had been evaluated for their impact on awareness or knowledge and twenty-seven for their impact on consumption. Furthermore sixteen interventions provided an evaluation of health impact, while three actions specifically measured any cost/benefit ratio. The indicators used in these evaluations were in most cases not comparable. Evaluation was more often found for public information campaigns, regulation of meals at schools/canteens and nutrition education programmes. Conclusions: The study highlights the need not only to develop harmonized and verifiable procedures but also indicators for measuring effectiveness and success and for comparing between interventions and countries. EU policies are recommended to provide a set of indicators that may be measured consistently and regularly in all countries. Furthermore, public information campaigns should be accompanied by other interventions, as evaluations may show an impact on awareness and intention, but rarely on consumption patterns and health outcome.

Policies to promote healthy eating in Europe: a structured review of policies and their effectiveness

This review provides a classification of public policies to promote healthier eating as well as a structured mapping of existing measures in Europe. Complete coverage of alternative policy types was ensured by complementing the review with a selection of major interventions from outside Europe. Under the auspices of the Seventh Framework Programme's Eatwell Project, funded by the European Commission, researchers from five countries reviewed a representative selection of policy actions based on scientific papers, policy documents, grey literature, government websites, other policy reviews, and interviews with policy-makers. This work resulted in a list of 129 policy interventions, 121 of which were in Europe. For each type of policy, a critical review of its effectiveness was conducted, based on the evidence currently available. The results of this review indicate a need exists for a more systematic and accurate evaluation of government-level interventions as well as for a stronger focus on actual behavioral change rather than changes in attitude or intentions alone. The currently available evidence is very heterogeneous across policy types and is often incomplete.

Biofuel policies in the EU, US and Brazil

The development of biofuels has been one of the most visible and controversial manifestations of the use of biomass for energy. Biofuels policies in the EU, US and Brazil have been particularly important for the development of the industry in these three important markets. All three have used a variety of measures, including consumption or use mandates, tax incentives and import protection to promote the production and use of biofuels. Despite this, it is uncertain whether the EU will achieve its objective of a 10 per cent share for renewables in transport fuels by 2020. The US is also running into difficulties in meeting consumption mandates for biofuels. Questions are being raised about the continuation of tax credits and import protection. Brazil has liberalised its domestic ethanol market and adopted a more market-oriented approach to biofuels policy, but the management of domestic petroleum prices and the inter-relationship between the sugar market and ethanol production are important factors affecting domestic consumption and exports. In both the EU and the US an ongoing debate about the benefits of reliance on biofuels derived from food crops and concern about the efficacy of current biofuels policies may put their future in doubt.

The relationship between European Community agricultural Structural Policies and their implementation and agricultural succession and inheritance within Member States

This paper presents an overview of the European Union involvement in agricultural restructuring. By way of introduction it looks at the processes of farm replication operating in Europe and the forces behind them. It then considers the wider application of EU measures in each Member State and how they interrelate with the national property laws and social customs. In conclusion the paper appraises the restructuring policies by examining the balance between legitimising the concentration of property rights amongst a minority and the fragmentation of estates between the majority.

Inequality, intergenerational mobility and redistributive policies under endogenous information

This paper presents a dynamic model to study how different levels of information about the root determinants of wealth (luck versus effort) can impact inequality and intergenerational mobility through societal beliefs, individual choices and redistributive policies. To my knowledge, the model presented is the first dynamicmodel in which skills are stochastic and both beliefs and voted redistribution are determined endogenously. The model is able to explain a number of empirical facts. Large empirical evidence shows that the difference in the political support for redistribution appears to reflect differences in the social perceptions regarding the determinants of individual wealth and the underlying sources of income inequality. Moreover the beliefs about the determinants of wealth impact individual choices of effort and therefore the beliefs about the determinants of wealth impact inequality and mobility both through choices of effort and redistributive policies. The model generates multiple equilibria (US versus Europe-type) which may account for the observed features not only in terms of societal beliefs and redistribution but also in terms of perceived versus real mobility and inequality.

Vision of the body and the differentiation of perceived body side in touch

Although tactile representations of the two body sides are initially segregated into opposite hemispheres of the brain, behavioural interactions between body sides exist and can be revealed under conditions of tactile double simultaneous stimulation (DSS) at the hands. Here we examined to what extent vision can affect body side segregation in touch. To this aim, we changed hand-related visual input while participants performed a go/no-go task to detect a tactile stimulus delivered to one target finger (e.g., right index), stimulated alone or with a concurrent non-target finger either on the same hand (e.g., right middle finger) or on the other hand (e.g., left index finger = homologous; left middle finger = non-homologous). Across experiments, the two hands were visible or occluded from view (Experiment 1), images of the two hands were either merged using a morphing technique (Experiment 2), or were shown in a compatible vs incompatible position with respect to the actual posture (Experiment 3). Overall, the results showed reliable interference effects of DSS, as compared to target-only stimulation. This interference varied as a function of which non-target finger was stimulated, and emerged both within and between hands. These results imply that the competition between tactile events is not clearly segregated across body sides. Crucially, non-informative vision of the hand affected overall tactile performance only when a visual/proprioceptive conflict was present, while neither congruent nor morphed hand vision affected tactile DSS interference. This suggests that DSS operates at a tactile processing stage in which interactions between body sides can occur regardless of the available visual input from the body.

Spatial coding of touch at the fingers: Insights from double simultaneous stimulation within and between hands

We studied the effect of tactile double simultaneous stimulation (DSS) within and between hands to examine spatial coding of touch at the fingers. Participants performed a go/no-go task to detect a tactile stimulus delivered to one target finger (e.g., right index), stimulated alone or with a concurrent non-target finger, either on the same hand (e.g., right middle finger) or on the other hand (e.g., left index finger=homologous; left middle finger=non-homologous). Across blocks we also changed the unseen hands posture (both hands palm down, or one hand rotated palm-up). When both hands were palm-down DSS interference effects emerged both within and between hands, but only when the non-homologous finger served as non-target. This suggests a clear segregation between the fingers of each hand, regardless of finger side. By contrast, when one hand was palm-up interference effects emerged only within hand, whereas between hands DSS interference was considerably reduced or absent. Thus, between hands interference was clearly affected by changes in hands posture. Taken together, these findings provide behavioral evidence in humans for multiple spatial coding of touch during tactile DSS at the fingers. In particular, they confirm the existence of representational stages of touch that distinguish between body-regions more than body-sides. Moreover, they show that the availability of tactile stimulation side becomes prominent when postural update is required.

Western Containment Policies in the Cold War; The Yugoslav Case, 1948-1953

Containment, as conceived by the US government official George Kennan, was an aggressive attempt to cause the Soviet Cold War empire to disintegrate. This can is demonstrated by the case study of how the USA, Britain, and France tried to instrumentalise renegade Tito's Yugoslavia as a wedge to break up the cohesion of the Communist regimes within the Soviet sphere. They supported Tito against subversion and planned Soviet-orchestrated military attack from its neighbouring states; Western plans for the support of Yugoslavia included plans for a selective use of nuclear weapons.
