Ever sceptical about the positivistic claims of ethnographic and so-called realist documentary, Johan van der Keuken’s film-making is the work of a curious, spontaneous and disorientated observer of the essential strangeness of both the foreign and the familiar, new landscapes and cities, experiences, and people. While there are various explicitly political and socially orientated films and themes across his work, it is those films and moments when what is being conveyed is a sense of him being somewhere liminal, being ‘in-between’ situations, cultures, styles and interpretations, reticent, uncertain but incorrigibly curious that constitute his most valuable contribution to documentary film aesthetics. Not surprisingly, such characteristics often come to the fore in those films where he tries to make sense of loss, the passing of lives and the legacies left behind. This article discusses questions of history and personal loss in a number of his films.

One habitat management requirement forced by 21st century relative sea-level rise (RSLR), will be the need to re-comprehend the dimensions of long-term transgressive behaviour of coastal systems being forced by such RSLR. Fresh approaches to the conceptual modelling and subsequent implementation of new coastal and peri-marine habitats will be required. There is concern that existing approaches to forecasting coastal systems development (and by implication their associated scarce coastal habitats) over the next century depend on a certain premise of orderly spatial succession of habitats. This assumption is shown to be questionable given the possible future rates of RSLR, magnitude of shoreline retreat and the lack of coastal sediment to maintain the protective morphologies to low-energy coastal habitats. Of these issues, sediment deficiency is regarded as one of the major problem for future habitat development. Examples of contemporary behaviour of UK coasts show evidence of coastal sediment starvation resulting from relatively stable RSLR, anthropogenic sealing of coastal sources, and intercepted coastal sediment pathways, which together force segmentation of coastal systems. From these examples key principles are deduced which may prejudice the existence of future habitats: accelerated future sediment demand due to RSLR may not be met by supply and, if short- to medium-term hold-the-line policies predominate, long-term strategies for managed realignment and habitat enhancement may prove impossible goals. Methods of contemporary sediment husbandry may help sustain some habitats in place but otherwise, instead of integrated coastal organization, managers may need to consider coastal breakdown, segmentation and habitat reduction as the basis of 21st century coastal evolution and planning.

Does the World Trade Organization function to reinforce American dominance (or hegemony) of the world economy? We examine this question via an analysis of trade disputes involving the United States. This allows us to assess whether the US does better than other countries in this judicialised forum: and in so doing enhance the competitive prospects of their firms. The results are equivocal. The United States does best in the early phases of a dispute, where political power is important. It does less well as the process develops.

The role played by firms in the prosecution of anti-dumping and countervailing duty cases in the United States is understudied. This article provides greater understanding of the challenges faced by firms during the process of prosecuting anti-dumping and countervailing duty cases in the United States. This is achieved by applying a theoretical model of corporate political activity to data collected through interviews with 24 trade attorneys in Washington, D.C., practising in the area of antidumping and countervailing duty law. Anti-dumping and countervailing duty cases are found to require significant resource commitments from firms in the participating industries, as well as requiring individual firms to make a number of strategic decisions. The value of an affirmative decision and imposition of duties to the domestic and foreign industry is found to be more nuanced than previous studies have suggested. Non-duty effects of AD and CVD cases are also confirmed. Finally a clearer understanding of the role of individual firms in anti-dumping and countervailing duty cases is shown to have the potential to improve how industry influence is taken account of in future research.

Photodynamic therapy of deep or nodular skin tumours is currently limited by the poor tissue penetration of the porphyrin precursor 5-aminolevulinic acid (ALA). In this study, silicon microneedle arrays were used, for the first time, to enhance skin penetration of ALA in vitro and in vivo. Puncturing excised murine skin with 6x7 arrays of microneedles 270 mum in height, with a diameter of 240 mum at the base and an interspacing of 750 mum led to a significant increase in transdermal delivery of ALA released from a bioadhesive patch containing 19 mg ALA cm(-2). Microneedle puncture enhanced ALA delivery to the upper regions of excised porcine skin but, at mean depths of 1.875 mm, ALA concentrations were similar to control values, possibly reflecting binding of ALA by tissue components. However, and importantly, in vivo experiments using nude mice showed that microneedle puncture could reduce application time and ALA dose required to induce high levels of the photosensitiser protoporphyrin IX in skin. This clearly has implications for clinical practice, as shorter application times would mean improved patient and clinician convenience and also that more patients could be treated in the same session. As ALA is expensive and degrades rapidly via a second order reaction, reducing the required dose is also a notable advantage.

How do multilateral institutions influence the strategic choices and actions of international managers? This paper addresses the question by exploring the impact of the World Trade Organization's (WTO) decision-making process on multinational enterprises (MNEs). We discuss the three phases of the WTO decision-making lifecycle - the formulation of trade rules, the implementation of those rules, and the enforcement of the rules – and propose a strategic adjustment framework for understanding how companies alter their strategies and structures in response to the WTO's rules and operations. We argue that the increased relevance of multilateral rules and enforcement mechanisms – embodied in the WTO - is an important influence on MNE strategies and structures because of the increasing embeddedness of the WTO in national levels of regulation. We illustrate this through examples taken from the pharmaceutical, textiles and sugar industries sectors that have witnessed substantial multilateral regulation.
