Introduction: The effectiveness of impact assessment instruments
The global application of impact assessment instruments to achieve a variety of policy integration goals (e.g. the mainstreaming of environmental, gender or economic efficiency concerns) continues to proliferate. These instruments represent important components of contemporary political governance and hence are an important locus for applied research. This special issue of Impact Assessment and Project Appraisal critically examines 'state-of-the-art' knowledge and understanding of the effectiveness of impact assessment instruments. Six articles explore this subject from a variety of orientations (in terms of theoretical versus empirical emphasis, policy integration concerns, contributors' beliefs and framing etc.). Individually and cumulatively, these articles make a powerful contribution to learning about the 'thorny' issue of effectiveness and its implications for the theory and practice of impact assessment
Interferometric Metrology Using Reprogrammable Binary Holograms
Interferometric methods for surface metrology have been widely used for many years due to their speed, accuracy and versatility. It is frequently necessary however to produce a known comparison reference surface to minimise the optical path difference and hence enhance the dynamic range. An alternative to this is to use a computer generated hologram to act as the reference wave, or to correct a spherical reference wave to match a highly aspheric optic in order to achieve a null test.
This thesis shall present a novel method of producing such holograms through the use of a binary ferroelectric liquid crystal on silicon spatial light modulator (FLCOS SLM) rather than using the more common lithographically produced plates. One of the primary advantages this could introduce is the ability for arbitrarily reprogrammable holograms to be created upon demand rather than needing to produce a series of holographic plates, saving both time and money in the testing of surfaces. We present results characterising the ability of a FLCOS SLM to produce increasingly large Zernike aberrations as well as quantifying the resulting errors, before using the device to reduce interferometric fringe density allowing us to measure aberrated optics and reveal low amplitude surface variations on the scale of 0.045 waves RMS
The Profumo affair in popular culture: The Keeler Affair (1963) and ‘the commercial exploitation of a public scandal’
This article demonstrates that the Profumo affair, which obsessed Britain for large parts of 1963, was not simply a political scandal, but was also an important cultural event. Focussing on the production of The Keeler Affair, a feature film that figured prominently in contemporary coverage of the scandal but which has been largely overlooked since, the article shows that this film emerged from a situation in which cultural entrepreneurs, many of them associated with the satire boom, sought to exploit the scandal for financial gain. Many Profumo-related cultural products found an audience, and thus formed an integral part of, and helped to shape public attitudes towards, the Profumo affair. However, these products did not go uncontested, and resistance to them, and especially to the idea that Keeler might benefit materially from her role in the scandal, speak to concerns about cultural mediations of sex, politics and humour in early-1960s Britain
Respatialization and local protest strategy formation: Investigating high-speed rail megaproject development in the UK
Understanding spatial conceptions is critical to the analysis of local protest strategy formation. Spatialities provoke inquiry into the drivers that may prompt local actors to adhere to particular strategies, and the implications this has on forms of contestation and the way protest is organized. It is argued that local protest can ‘respatialize’ when actors are embedded in social movements and translocal assemblages associated with controversy over development, and that this warrants reconsidering the role of ‘place’. A case study of a proposed megaproject framed in the national interest – a high-speed rail network called HS2, in the United Kingdom – is used to investigate local protest respatialization. Fieldwork was conducted in the Chilterns, an area of high scenic beauty which will be adversely impacted by HS2. The results show how the perceived need to respatialize protest away from the local to the national domain reconfigures debate to focus primarily on economic issues. Respatialization also has implications for the dynamics of protest assemblages with unlikely alliances developing around a need to engage with or engender debate in the national polity. It is concluded that local actors may opt to respatialize their protest in response to their interaction with social movements and protest assemblages that disengage from specific place-based interests. The paper recommends that future research on the geographies of social action take forward spatialization as a powerful lens for investigating protest strategy formation
Preventing Violence in Seven Countries: Global Convergence in Policies
Do governments take the measures that are supported by the best scientific evidence available? We present a brief review of the situation in: Australia, Canada, Germany, the Netherlands, Spain, the United Kingdom, and the United States. Our findings show surprisingly similar developments across countries. While all seven countries are moving towards evidence-based decision making regarding policies and programs to prevent violence, there remain a number of difficulties before this end can be achieved. For example, there continue to be few randomized controlled trials or rigorous quasi-experimental studies on aggression and violence. Results from experimental research are essential to both policy makers and researchers to determine the effectiveness of programs as well as increase our knowledge of the problem. Additionally, all noted that media attention for violence is high in their country, often leading to management by crisis with the result that policies are not based on evidence, but instead seek to appease public outrage. And perhaps because of attendant organizational problems (i.e., in many countries violence prevention was not under the guise of one particular agency or ministry), most have not developed a coordinated policy focusing on the prevention of violence and physical aggression. It is hypothesized that leaders in democratic countries, who must run for election every 4 to 6 years, may feel a need to focus on short-term planning rather than long-term preventive policies since the costs, but not the benefits for the latter would be incurred while they still served in office. We also noted a general absence of expertise beyond those within scientific circles. The need for these ideas to be more widely accepted will be an essential ingredient to real and sustaining change. This means that there must be better communication and increased understanding between researchers and policy makers. Toward those ends, the recent establishment of the Campbell Collaboration, formed to provide international systematic reviews of program effectiveness, will make these results more available and accessible to politicians, administrators and those charged with making key policy decision
