Two particle states, lepton mixing and oscillations
Discussions of lepton mixing and oscillations consider generally only flavor
oscillations of neutrinos and neglect the accompanying charged leptons. In
cases of experimental interest like pion or nuclear beta decay an oscillation
pattern is expected indeed only for neutrinos if only one of the two produced
particles is observed. We argue that flavor oscillations of neutrinos without
detecting the accompanying lepton is a peculiarity of the two-particle states
produced in pion or nuclear beta decay. Generally, an oscillation
pattern is only found if both particles are detected. We discuss in a
pedagogical way how this distinction of the neutrinos arises, although on the
level of the Lagrangian lepton mixing does not single them out against charged
leptons. As examples, we discuss the difference between the state
produced by the decay of real boson and a originating from pion decay
Meat consumption: Trends and quality matters
peer-reviewedThis paper uses quality theory to identify opportunities for the meat sector that are consistent with trends in meat consumption. Meat consumption has increased and is likely to continue into the future. Growth is largely driven by white meats, with poultry in particular of increasing importance globally. The influence of factors such as income and price is likely decline over time so that other factors, such as quality, will become more important. Quality is complex and consumers' quality expectations may not align with experienced quality due to misconception of certain intrinsic cues. Establishing relevant and effective cues, based on extrinsic and credence attributes, could offer advantage on the marketplace. The use of extrinsic cues can help convey quality characteristics for eating quality, but also for more abstract attributes that reflect individual consumer concerns e.g. health/nutrition, and collective concerns, e.g. sustainability. However, attributes are not of equal value to all consumers. Thus consumer segmentation and production differentiation is needed.The authors acknowledge the financial support of the Irish Department of Agriculture Food and Marine for funding through their Stimulus Fund for the project entitled âGenetic selection for improved milk and meat product quality in dairy, beef and sheepâ: project reference no: 11/SF/311
