Public sector controllership—reinventing the financial specialist as a countervailing power

Different types of ‘controllers’ can be distinguished in the public sector. The authors’ research indicates that public sector controllers acknowledge the distinctive characteristics of ‘hybrid’ controllers, but question some of the possible advantages of ‘pure’ controllers. This result could signal a decreasing share of pure controllers and thus a loss of financial expertise in the public sector. This article calls for the controller to be ‘re-invented’ as a professional who combines solid financial expertise with an independent and critical attitude towards overly ambitious politicians and managers. The general public’s support for public sector organizations could be enhanced if strong controllers counterbalance the sometimes too optimistic views of managers and politicians

Infrared Resonance Enhanced Multiphoton Ionization of Fullerenes

Gas-phase fullerenes are resonantly heated by a train of high power subpicosecond pulses from a free electron laser (FEL) to internal energies at which they efficiently undergo delayed ionization. When the laser is tuned from 6–20μm while the amount of laser produced parent ions is recorded, resonant absorption of 200–600 IR photons, resulting in almost fragmentation-free ion spectra, is observed. Infrared resonance enhanced multiphoton ionization with a FEL is shown to enable extremely sensitive IR spectroscopy with mass selective detection of gas-phase fullerenes

Mid-Infrared Imaging and Modelling of the Dust Shell around Post-AGB star HD 187885 (IRAS 19500-1709)

We present 10 and 20 micron images of IRAS 19500-1709 taken with the mid-infrared camera, OSCIR, mounted on the Gemini North Telescope. We use a 2-D dust radiation transport code to fit the spectral energy distribution from UV to sub-mm wavelengths and to simulate the images.Comment: 4 pages, 5 figures.

Towards Eliminating Bias in Cluster Analysis of TB Genotyped Data

The relative contributions of transmission and reactivation of latent infection to TB cases observed clinically has been reported in many situations, but always with some uncertainty. Genotyped data from TB organisms obtained from patients have been used as the basis for heuristic distinctions between circulating (clustered strains) and reactivated infections (unclustered strains). Naïve methods previously applied to the analysis of such data are known to provide biased estimates of the proportion of unclustered cases. The hypergeometric distribution, which generates probabilities of observing clusters of a given size as realized clusters of all possible sizes, is analyzed in this paper to yield a formal estimator for genotype cluster sizes. Subtle aspects of numerical stability, bias, and variance are explored. This formal estimator is seen to be stable with respect to the epidemiologically interesting properties of the cluster size distribution (the number of clusters and the number of singletons) though it does not yield satisfactory estimates of the number of clusters of larger sizes. The problem that even complete coverage of genotyping, in a practical sampling frame, will only provide a partial view of the actual transmission network remains to be explored
