Consumer demand for informative labeling of quality food and drink products: a European Union case study

Abstract: Purpose – The purpose of this work is to examine the range of information consumers seek on labels of quality products and construct an indicative check‐list of various types of informational labeling as well as to examine whether quality of information demanded segregates the market‐creating segments to be targeted by firms.Design/methodology/approach – An extensive interdisciplinary literature review based on findings in marketing, economics, geography and sociology reveals the often neglected range of factors forcing consumers to place importance on regionally denominated food and drink. The European Union (EU) has responded to growing consumer trends towards regional and traditional food and established special schemes regulating the production of such food and drink. A survey of 640 consumers of quality wine carried out within the framework of an EU‐funded program provides the empirical material of this work.Findings – The study records the range of informational labeling sought by consumers as well ...

Orbital dynamics of three-dimensional bars — III. Boxy/peanut edge-on profiles

Abstract: We present families, and sets of families, of periodic orbits that provide building blocks for boxy and peanut (hereafter b/p) edge-on profiles. We find cases where the b/p profile is confined to the central parts of the model and cases where a major fraction of the bar participates in this morphology. A b/p feature can be built either by 3D families associated with 3D bifurcations of the x1 family, or, in some models, even by families related with the z-axis orbits and existing over large energy intervals. The ‘X’ feature observed inside the boxy bulges of several edgeon galaxies can be attributed to the peaks of successive x1v1 orbits, provided their stability allows it. However in general, the x1v1 family has to overcome the obstacle of a S → � → S transition in order to support the structure of a b/p feature. Other families that can be the backbones of b/p features are x1v4 and z3.1s. The morphology and the size of the boxy or peanut-shaped structures we find in our models are determined by the presence and stability of the families that support b/p features. The present study favours the idea that the observed edge-on profiles are the imprints of families of periodic orbits that can be found in appropriately chosen Hamiltonian systems, describing the potential of the bar.
