This paper describes an empirical investigation into the nature of challenge within the context of flow or effortless attention. An important condition of the flow state is that the challenges of the task are commensurate with the person’s level of skill. However when considering movement interaction those challenges could be composite in the sense that they could comprise physical as well as i...

The blocks of a balanced ternary design, BTD(V,B; ρ1, ρ2, R;K,Λ), can be partitioned into two sets: the b1 blocks that each contain no repeated elements, and the b2 = B − b1 blocks containing repeated elements. In this note, we address, and answer in some particular cases, the following question. For which partitions of the integer B as b1 + b2 does there exist a BTD(V,B; ρ1, ρ2, R;K,Λ)?

Given a set of n black and n white points in general position in the plane, a line l determined by them is said to be balanced if each open half-plane bounded by l contains precisely the same number of black points as white points. It is proved that the number of balanced lines is at least n. This settles a conjecture of George Baloglou.

Let S be a set of r red points and b = r + 2δ blue points in general position in the plane, with δ ≥ 0. A line l determined by them is balanced if in each open half-plane bounded by l the difference between the number of blue points and red points is δ. We show that every set S as above has at least r balanced lines. The main techniques in the proof are rotations and a generalization, sliding r...

Background There is limited evidence to inform nutrition and dietetic interventions for individuals with eating disorders even though it is recommended as an essential part of multidisciplinary management. There is minimal guidance, an absence of standardised nutrition educational material, and no research on how best to educate patients on healthy eating and how to achieve nutrition adequacy. ...

A blended diet for enteral nutrition is defined as home-made everyday food blended to a smooth 'single cream' consistency. At present, blended food is not recommended as a first choice. However, the wishes of parents who prefer to use blended food for their child need to be respected, and hospice policy for Children's Hospice South West is to replicate home conditions as far as possible. Theref...
