This paper describes a method for working with chldren who are the subjects of care planning and review under the Children Act 1989. The person centred planning model, as it is termed, has been well established in working with adults with special needs but can be extrapolated to encounters with children. It focuses on three fundamental areas: relationship, meaning and narrative. In underscoring these areas, the method restrains the bureaucracy and experience of stigma that is often present for those residing in State care.

This review examines the developments in optical biosensor technology, which uses the phenomenon of surface plasmon resonance, for the detection of paralytic shellfish poisoning (PSP) toxins. Optical biosensor technology measures the competitive biomolecular interaction of a specific biological recognition element or binder with a target toxin immobilised onto a sensor chip surface against toxin in a sample. Different binders such as receptors and antibodies previously employed in functional and immunological assays have been assessed. Highlighted are the difficulties in detecting this range of low molecular weight toxins, with analogues differing at four chemical substitution sites, using a single binder. The complications that arise with the toxicity factors of each toxin relative to the parent compound, saxitoxin, for the measurement of total toxicity relative to the mouse bioassay are also considered. For antibodies, the cross-reactivity profile does not always correlate to toxic potency, but rather to the toxin structure to which it was produced. Restrictions and availability of the toxins makes alternative chemical strategies for the synthesis of protein conjugate derivatives for antibody production a difficult task. However, when two antibodies with different cross-reactivity profiles are employed, with a toxin chip surface generic to both antibodies, it was demonstrated that the cross-reactivity profile of each could be combined into a single-assay format. Difficulties with receptors for optical biosensor analysis of low molecular weight compounds are discussed, as are the potential of alternative non-antibody-based binders for future assay development in this area.

This paper examines a select number of poems by Middle Generation poets John Berryman and Anne Sexton in relation to questions of death, silence and the task that literature sets itself as understood in key works by Blanchot, Heidegger, and Levinas. Rather than recourse to the overtrodden critical path of confessional interpretations of their work, this paper connects Berryman’s The Dream Songs (1969) and two Sexton poems (‘Oh’ and ‘The Silence’) to the philosophical determinations of what it is language can say and what demands literature makes of the writer prepared to risk their own being in answer to its call. Central issues such as suicide and the originating silence of the work of art are intricately interwoven with Berryman’s and Sexton’s work. Leaving aside their biographies, and by approaching suicide as a philosophical problem with which their poetry wrestles, a restructured approach to their work becomes available. The impulse to suicide and the mental processes involved in considering and committing the act are instincts and responses located within an individual’s own psychology. For these writers particularly such issues are sited within a philosophical debate about language, what it can and cannot represent. If poetry articulates language’s argument about its own capability, it is the ideal forum for philosophical confrontations with the possibilities of existence as represented by the grave decision to take one’s own life. © The Author 2013.
