This paper explores the organisational experiences of governmental policy change and implementation on the third sector. Using a four-year longitudinal study of 13 third sector organisations (TSOs) it provides evidence based on the experiences of, and effects on, third sector organisations involved in the UK’s Work Programme in Scotland. The paper explores third sector experiences of the Work Programme during the preparation and introductory phase, as well as the effects of subsequent Work Programme implementation. By gathering evidence contemporaneously and longitudinally a unique in-depth analysis is provided of the introduction and implementation of a major new policy. The resource cost and challenges to third sector ways of working for the organisations in the Work Programme supply chain, as well as those not in the supply chain, are considered. The paper considers some of the responses adopted by the third sector to manage the opportunities and challenges presented to them through the implementation of the Work Programme. The paper also reflects on the broader context of the employability services landscape and raises questions as to whether, as a result of the manner in which the Work Programme was contracted, there is evidence of a move towards service homogenisation, challenging perceived TSO characteristics of service innovation and personalisation.

In many multi-camera vision systems the effect of camera locations on the task-specific quality of service is ignored. Researchers in Computational Geometry have proposed elegant solutions for some sensor location problem classes. Unfortunately, these solutions utilize unrealistic assumptions about the cameras' capabilities that make these algorithms unsuitable for many real-world computer vision applications: unlimited field of view, infinite depth of field, and/or infinite servo precision and speed. In this paper, the general camera placement problem is first defined with assumptions that are more consistent with the capabilities of real-world cameras. The region to be observed by cameras may be volumetric, static or dynamic, and may include holes that are caused, for instance, by columns or furniture in a room that can occlude potential camera views. A subclass of this general problem can be formulated in terms of planar regions that are typical of building floorplans. Given a floorplan to be observed, the problem is then to efficiently compute a camera layout such that certain task-specific constraints are met. A solution to this problem is obtained via binary optimization over a discrete problem space. In preliminary experiments the performance of the resulting system is demonstrated with different real floorplans.
