A new species of Phyllophaga Harris from the island of Navassa in the Caribbean (Coleoptera: Scarabaeidae: Melolonthinae)

The small Caribbean island of Navassa (U.S. possession) is unoccupied by humans, but recent surveys have detected a surprising number of endemic (precinctive) invertebrates. A new species of May beetle, Phyllophaga navassa, is here described and compared to the Hispaniolan Phyllophaga fauna

THE VALUATION OF LABELLING ATTRIBUTES IN A WINE MARKET

The values which market participants place on labelling information in the British wine retail market are investigated using a hedonic framework. The results suggest a near asymmetric evaluation of labelling attributes between wines from the 'New World' (Australia) and wines from the 'Old World' (France). The benefits of studying the valuation of attribute information within the hedonic framework are demonstrated in two steps. First, the revenue impact of shifts in attributes is examined at the retail level. Second, the welfare impact of changes in the attribute choice set facing consumers is considered.Marketing,

An Asian darkling beetle, Ceropria induta (Wiedemann), established in Florida (Coleoptera: Tenebrionidae)

Specimen records for an adventive darkling beetle, Ceropria induta (Wiedemann) (Coleoptera: Tenebrionidae; Diaperinae) show that this Asian insect has become established in southern Florida, USA. Illustrations and a diagnosis of the beetle are provided, with notes on habitats and possible polyporaceous hosts, and the genus is incorporated into a key to the related North American taxa

Electromagnetic Mach principle

We will introduce a gauge model which an electromagnetic coupling constant and local mass are related to all the charge in the universe. we will use the standard Dirac action, but where the mass and the electromagnetic coupling constant are a function of the sum of all the charge in the universe, which represent Mach principle for electromagnetic coupling constant. The formalisation is not manifestly Lorentz invariant, however Lorentz invariance can be restored by performing a phase transformation of the Dirac field.Comment: 3 page

Confining Boundary conditions from dynamical Coupling Constants

It is shown that it is possible to consistently and gauge invariantly formulate models where the coupling constant is a non trivial function of a scalar field . In the $U(1)$ case the coupling to the gauge field contains a term of the form $g(\phi)j_\mu (A^{\mu} +\partial^{\mu}B)$ where $B$ is an auxiliary field and $j_\mu$ is the Dirac current. The scalar field $\phi$ determines the local value of the coupling of the gauge field to the Dirac particle. The consistency of the equations determine the condition $\partial^{\mu}\phi j_\mu = 0$ which implies that the Dirac current cannot have a component in the direction of the gradient of the scalar field. As a consequence, if $\phi$ has a soliton behaviour, like defining a bubble that connects two vacuua, we obtain that the Dirac current cannot have a flux through the wall of the bubble, defining a confinement mechanism where the fermions are kept inside those bags. Consistent models with time dependent fine structure constant can be also constructedComment: 4 pages, 3 figures. A new reference added and discussion expande
