While segmenting consumers, it is beneficial to understand how emotions and sensory perceptions relate to consumers' food behavior. In this research, a new measure called the "local embeddedness" (EMB) scale was used to measure the emotional bond with the region among 1,714 respondents from 15 countries. There were two aims of the study: firstly, to examine the effectiveness of the EMB scale in segmenting respondents, and secondly, to profile the EMB segments in terms of socio-demographic variables. Results show that EMB segments consisted of three groups of respondents: 1) strong local supporters, 2) confused disbelievers, and 3) limited knowledge about product origin/trust industry segment. © 2013 Copyright Taylor and Francis Group, LLC.

Biological indicators are highly relevant for assessing the condition of a soil as they are integrative; they reflect the overall impact of physical, chemical and biological changes. Indigenous soil organisms are preferable to other test organisms because the diversity and condition of indigenous soil organisms reflect both acute and chronic effects of soil disturbances. Nematodes are ubiquitous, speciose, easily extractable and present in extremely high numbers. Given the ever increasing amount of sequence data, DNA barcode-based community analysis will soon be possible and a next step would be to define objective criteria for the ecological grouping of soil nematodes. Here, we present a framework to ascertain which traits are correlated with a tolerance to stress. For this, a field study on the effects of pH and copper on nematode communities was re-analysed. Changes in abundances of individual genera were correlated with a number of potentially stress tolerance-related characteristics. The generalised least squares (GLS) method was used to account for the phylogenetic dependence of the data. Only the relationship between the ability to enter a survival stage and tolerance to copper at pH 6.1 was found to be significant, but the quantity of missing data probably had a negative impact on the analyses. This study did, however, clearly demonstrate the importance of accounting for the effects of phylogenetic dependence in the data. When the phylogeny was taken into account, we observed an average change in P value of 0.196 (and in some cases as much as 0.6) for the correlations of possible stress-related characteristics and Cu or pH tolerance. This research constitutes a proof-of-principle for a transparent method to relate stress tolerance to (ecological) characteristics. The usefulness of this powerful method should become even clearer when substantially higher numbers of individuals are analysed (as facilitated by using DNA barcodes) and when missing data are filled in. © 2011 Brill.

Various methods for the harmonization of the registration of crop protection products and dose adjustments in high growing crops have been discussed over many years. The leaf wall area (LWA) method has been known for some years already but it has received renewed attention due to a proposal by the European agrochemical manufacturing industry for harmonizing the dose expression in view of the new zonal registration system in the EU. The LWA method appears not only suitable for fruit trees and vineyards, but may also prove a simple and widely accepted method for dose adjustments in high growing vegetable crops particularly in greenhouses. This paper provides a dataset on leaf wall area and leaf area development for a selection of commercially grown cucumber, eggplant, sweet pepper and tomato varieties in Switzerland. Relationships between leaf wall area and leaf area have been established. A tentative product dose adjustment to growing vegetable crops in greenhouses is given for Switzerland. Biological efficacy trials will be required to validate the LWA method. © 2012 OEPP/EPPO.
