It's complicated: apprentice leaders on the edge of chaos

A view from the dance floor of ALICSE participants showed that the integrated children's services remain under pressure to become multi-dimensional with the rhetorical push to a joint working becoming increasingly complex and difficult to navigate. This was the view of a 360 degree questionnaire to a number of ALICSE participants and reflections from an in-depth dialogue. The main findings suggested collective professionalism requires collaborative relationships between organisations and individuals, and this collaboration poses the most significant challenge for educational leadership and management. The participants on the dance floor often reciting phrases like: letting go of control, no hierarchy, self-organising. The main conclusion being an individual needs to be self-organised and it takes a leader to be confident to manage ambiguity and complexity. Using complex adaptive systems theory and blended leadership styles theories, we will assert that distributional leadership is required to navigate the complex environment. Futures thinking suggests that we could use complex adaptive systems theory to help build an effective communication strategy for individuals, teams and services allowing them to self-organise

Computer program for the design of axial-flow turbines

Computer program, capable of analyzing single and multispool units, computes absolute and relative flow fields within the turbine at the first stator inlet, at each interblade row plane, and at the final rotor exit. No simplifying assumptions are made which would result in restrictive design

Techniques for studying gravity waves and turbulence: Horizontal, vertical and temporal resolution needed

One of the most important atmospheric measurements that is needed is a measure of the gravity-wave spectrum. The MST radar has been investigated as means to measure the temporal resolution required to determine gravity-wave oscillations. The required vertical and horizontal resolution is dependent on the particular part of the gravity wave spectrum that is analyzed. Horizontal spacing is also discussed

Design optimisation of multistage depressed collectors for high efficiency travelling wave tubes using genetic algorithm.

The design of a symmetric and an asymmetric collector has been optimised using the genetic algorithm. The improvement in collector efficiency in both cases is remarkable

Integrability and the Kerr-(A)dS black hole in five dimensions

In this note we prove that the Hamilton-Jacobi equation for a particle in the five dimensional Kerr-(A)dS black hole is separable, for arbitrary rotation parameters. As a result we find an irreducible Killing tensor. We also consider the Klein-Gordon equation in this background and show that this is also separable. Finally we comment on extensions and implications of these results.Comment: 4 pages, RevTeX. v2: minus sign typos in eq. (17) and (18) of published version correcte

Fields in Nonaffine Bundles. I. The general bitensorially covariant differentiation procedure

The standard covariant differentiation procedure for fields in vector bundles is generalised so as to be applicable to fields in general nonaffine bundles in which the fibres may have an arbitrary nonlinear structure. In addition to the usual requirement that the base space should be flat or endowed with its own linear connection, and that there should be an ordinary gauge connection on the bundle, it is necessary to require also that there should be an intrinsic, bundle-group invariant connection on the fibre space. The procedure is based on the use of an appropriate primary-field (i.e. section) independent connector that is constructed in terms of the natural fibre-tangent-vector realisation of the gauge connection. The application to gauged harmonic mappings will be described in a following article.Comment: 17 page Latex file with some minor misprint corrections and added color for article originally published in black and whit
