Aerial observations of light pollution can fill an important gap between ground based surveys and nighttime satellite data. Terrestrially bound surveys are labor intensive and are generally limited to a small spatial extent, and while existing satellite data cover the whole world, they are limited to coarse resolution. This paper describes the production of a high resolution (1 m) mosaic image of the city of Berlin, Germany at night. The dataset is spatially analyzed to identify themajor sources of light pollution in the city based on urban land use data. An area-independent 'brightness factor' is introduced that allows direct comparison of the light emission from differently sized land use classes, and the percentage area with values above average brightness is calculated for each class. Using this methodology, lighting associated with streets has been found to be the dominant source of zenith directed light pollution (31.6%), although other land use classes have much higher average brightness. These results are compared with other urban light pollution quantification studies. The minimum resolution required for an analysis of this type is found to be near 10 m. Future applications of high resolution datasets such as this one could include: studies of the efficacy of light pollution mitigation measures, improved light pollution simulations, economic and energy use, the relationship between artificial light and ecological parameters (e.g. circadian rhythm, fitness, mate selection, species distributions, migration barriers and seasonal behavior), or the management of nightscapes. To encourage further scientific inquiry, the mosaic data is freely available at Pangaea.

This article draws on the author's experience of living and working in Belfast, Northern Ireland. Connections between the traumatic events of September 11 and the situation in the north of Ireland of ongoing civil conflict and violence are developed and aspects of therapeutic practice are described. Coping with the effects of trauma presents systemic therapists with multiple and complex challenges in whatever sociopolitical context they practice. A therapist stance that combines flexibility and openness of attitude with the creative use of therapeutic practices, including those from other modalities, will assist systemic therapists in rising to these challenges.

11 September heralded and provided a pretext for a more aggressive but increasingly contradictory American hegemony. Some of the consequences are contrary to the United States' own interests. Its new doctrine of 'preemptive strike' against other sovereign states encourages similarly belligerent behaviour by other governments, and yet more terrorism by nonstate actors, the very threats which were to be eradicated by a re-asserted US hegemony. This essay focuses on three partly overlapping themes: different strategies towards allies - multilateral and unilateral; different forms of power - civil and military; and different ideologies of globalisation - neoliberal and neo-conservative. It argues that while US policy may oscillate between such poles, it often combines the different elements. The overall strategy of the Bush administration is best characterised as unilateral multilateralism. The main issue for US hegemonists is the ways in which their hegemony might best be exercised, maintained and strengthened vis à vis allies and rivals. But for a safer, more democratic world, the choice does not lie between one faction of US hegemonists and another: we need other alternatives such as cosmopolitan democracy and a genuine internationalist movement which would give it some much-needed substance.
