Short cuts to dynamic factor demand modelling

By means of so-called virtual or shadow prices, short-run factor demands, short-run marginal costs, etc. can be derived from any long-run cost function. The traditional approach (short-run/restricted/conditional/variable cost functions) is criticized, and it is also shown that technological change, scale e!ects, etc. can be added to any cost function by means of disembodied factor-augmenting e$...

Small Cuts – Creating Small Short Films

Discussions about mobile applications and businesses often deal with technical issues on distribution and representation. Content, when discussed, is typically considered as a set of measurable units, like size, form and version, and left with that. This paper stresses the importance of also regarding content as the result of a creative process. A content theory is presented and used as a backd...

Short cuts in higher dimensional space

Short-Cuts on Star, Source and Planar Unfoldings

When studying a 3D polyhedron, it is often easier to cut it open and atten in on the plane. There are several ways to perform this unfolding. Standard unfoldings which have been used in literature include Star Unfoldings, Source Unfoldings, and Planar Unfoldings, each di ering only in the cuts that are made. Note that every unfolding has the property that a straight line between two points on t...

Maximum cuts and judicious partitions in graphs without short cycles

We consider the bipartite cut and the judicious partition problems in graphs of girth at least 4. For the bipartite cut problem we show that every graph G with m edges, whose shortest cycle has length at least rX4; has a bipartite subgraph with at least m 2 þ cðrÞm r rþ1 edges. The order of the error term in this result is shown to be optimal for r 1⁄4 5 thus settling a special case of a conjec...

On Short Cuts - or - Fencing in Rectangular Strips

In this paper we consider an isoperimetric inequality for the free perimeter of a planar shape inside a rectangular domain, the free perimeter being the length of the shape boundary that does not touch the border of the domain.
