Local Hidden Variables Underpinning of Entanglement and Teleportation
Entangled states whose Wigner functions are non-negative may be viewed as
being accounted for by local hidden variables (LHV). Recently, there were
studies of Bell's inequality violation (BIQV) for such states in conjunction
with the well known theorem of Bell that precludes BIQV for theories that have
LHV underpinning. We extend these studies to teleportation which is also based
on entanglement. We investigate if, to what extent, and under what conditions
may teleportation be accounted for via LHV theory. Our study allows us to
expose the role of various quantum requirements. These are, e.g., the
uncertainty relation among non-commuting operators, and the no-cloning theorem
which forces the complete elimination of the teleported state at its initial
port.Comment: 24 pages, 1 figure, accepted Found. Phy

How would you recognise an expert coach if you saw one?
A review of the literature that frames coaching practice and specifically the formation and determination of expert coaching practice reveals a body of research that lacks continuity. It has recently been argued that much of the instability surrounding our professional interpretation of coaching practice stems from a penchant for subjective investigation. This analysis draws on a review of over 100 peer reviewed articles, chapters and books – all published within the last 35 years, that address the notion of coaching practice. The findings of this analysis suggests that much of the research used to establish conceptual clarity fails to distinguish between highly organised or efficient coaching practice and expert coaching practice. This paper concludes with some recommendations from alternate paradigms which suggest that expertise in interceptive sports coaching may be better theorised and suitably identified through a lens of the growing ideas surrounding ‘emergence’
