| This paper evaluates concerns over the "abandonment of production" in the context of the recent CAP reform as it applies to the arable sector. The particular focus of the evaluation is on the extent to which the proposed "single farm payment" can be de-coupled from production and yet avoid the abandonment of land on which production is expected to be profitable. An analytical framework is developed which indicates the most important non-policy factors are the profitability of the land, the variability of yield and the grower's degree of risk aversion. The conclusion of a numerical analysis using this framework is that 85% de-coupling is unlikely to lead to abandonment of land in any arable region of the EU, and that 95% de-coupling is also unlikely to lead... |

| A bovine 5,000 rad WG-RH panel was used to construct an RH map of bovine chromosome 5 (BTA5). Twenty-one microsatellites and thirteen genes were scored in the panel using PAGE and radioactive labeling. Marker retention ranged from 8.9%-25.8% and averaged 17.8%. Pairwise locus analysis placed all markers in a single syntenic group with a LOD support of 4.0. At a LOD support of 8.0, a centromeric group of 23 syntenic markers was formed. Telomeric groups of 11 and 9 markers were assembled with a LOD support of 6.0 and 8.0, respectively. All markers were ordered by maximum likelihood methods using the program RHMAP. Only 13 markers were ordered with a LOD support of at least 3.0, while 25 and 29 markers were ordered with a support of at least 2.0 and 1.0,... |

| Consumers' attitudes to trust and risk are key issues in food safety research and attention needs to be focused on clearly defining a framework for analysing consumer behaviour in these terms. By creating a platform, or benchmark, it is hoped that more succinct policy programmes may be initiated to better communicate relevant issues to consumers. In order to achieve this, a detailed review of the recent literature surrounding risk, trust and, the relationship between the two must be conducted. This paper aims to collate the literature in the fields of consumer attitudes to trust and risk. It provides an insight into the economic and other modelling procedures available to measure consumers' attitudes to risk and trust in food safety and specifically notes... |

| Food allergy is most frequently the result of IgE-mediated hypersensitivity reactions. Here, we describe a chronic model in which some of the intestinal and systemic consequences of continuous egg white solution ingestion by ovalbumin-sensitized eight-week-old BALB/c mice, 6 animals per group, of both sexes, were investigated. There was a 20% loss of body weight that began one week after antigen exposure and persisted throughout the experiment (3 weeks). The sensitization procedure induced the production of anti-ovalbumin IgG1 and IgE, which were enhanced by oral antigen exposure (129% for IgG1 and 164% for IgE, compared to sensitization values). Intestinal changes were determined by jejunum edema at 6 h (45% Evans blue extravasation) and by a significant... |

| The dispersal of Pectinaria koreni larvae released from the eastern Bay of Seine (English Channel) was studied using a two-dimensional hydrodynamic model which integrates tides, wind-driven currents and eddy diffusion, in order to examine the influence of environmental forcing and mortality on larval population dynamics. A broad agreement between predicted larval dispersal for two spawning events observed in 1987 and field data suggests that numerical modelling may be useful to analyse processes involved in the transport and the dynamics of larval populations. Larval mortality may be as important as hydrodynamic processes on larval losses for the adult population. Tides and eddy diffusion had some effects on larval dispersal, but wind forcing and the... |

| Conhecer e reconhecer o papel da mulher agricultora nos novos processos produtivos em curso voltados a atualizar o lugar do rural nas sociedades contemporâneas, a partir do sistema de produção da agricultura orgânica, é a pretensão maior deste trabalho. Interessa identificar as estratégias adotadas pela agricultura familiar para a dinamização e manutenção de modos de viver o meio rural, ao mesmo tempo que interessa identificar as possibilidades de trazer à visibilidade o espaço rural nas sociedades modernas. Nesse contexto é que se pesquisou a agricultura orgânica na Região Metropolitana de Curitiba (RMC), analisou-se quem são os agricultores envolvidos no processo e, dentro dele, buscou-se apontar o papel que a mulher agricultora desempenha, desde o... |

| This paper estimates the willingness to pay (WTP) for non-genetically modified (GM) vegetable oil and tofu in Korea by using contingent valuation (CV) method and compares this WTP with Japan, Norway, Taiwan and the U.S. It also recovers the distribution of WTP by using a bootstrapping approach to provide a better measure of consumer's WTP on non-GM foods. Especially, we pay attention to the different characteristics of vegetable oil and tofu; vegetable oil made from GM soybeans doesn't have genetically altered protein, but tofu made from GM soybean has genetically altered protein. For this reason, vegetable oil made from GM soybeans is excluded from mandatory GM labeling system in Korea. Therefore, in this paper, the potential differences between WTP for... |

| A multinomial logit analysis is employed to analyze consumers' perceptions about purchasing biotech foods and their preferences for mandatory and voluntary labeling. Results showed that consumers who are sensitive to the possible side effects of biotech crops on wildlife and the environment are more likely to support a mandatory labeling policy. Results also indicated that respondents who believe biotech foods may have unforeseen health risks are more likely to favor mandatory labeling. Furthermore, the study found that respondents who are willing to buy a meat product produced using biotechnology are more likely to favor a voluntary labeling policy. |
