Recent data suggest no further recovery in North Sea Large Fish Indicator

We detail the calculations of North Sea Large Fish Indicator values for 2009-2011, demonstrating an apparent stall in recovery. Therefore, recovery to the Marine Strategy Framework Directive's good environmental status of 0.3 by the 2020 deadline now looks less certain and may take longer than was expected using data from 2006 to 2008.

Quotients, exactness, and nuclearity in the operator system category

We continue our study of tensor products in the operator system category. We define operator system quotients and exactness in this setting and refine the notion of nuclearity by studying operator systems that preserve various pairs of tensor products. One of our main goals is to relate these refinements of nuclearity to the Kirchberg conjecture. In particular, we prove that the Kirchberg conjecture is equivalent to the statement that every operator system that is (min,er)-nuclear is also (el,c)-nuclear. We show that operator system quotients are not always equal to the corresponding operator space quotients and then study exactness of various operator system tensor products for the operator system quotient. We prove that an operator system is exact for the min tensor product if and only if it is (min,el)-nuclear. We give many characterizations of operator systems that are (min,er)-nuclear, (el,c)-nuclear, (min,el)-nuclear and (el,max)-nuclear. These characterizations involve operator system analogues of various properties from the theory of C*-algebras and operator spaces, including the WEP and LLP.

CMOS IMPLEMENTATION OF A SYSTOLIC MULTI-BIT CONVOLVER CHIP.

The implementation of a multi-bit convolver chip based on a systolic array is described. The convolver is fabricated on a 7mm multiplied by 8mm CMOS chip and operates on 8-bit serial data and coefficient words. It has a length of 17 stages, and this is cascadable. The circuit can be clocked at more than 20 MHz giving a data throughput rate of greater than 1 Mword/s. Details of important implementation decisions and a summary of chip characteristics are given together with the advantages which the systolic approach has afforded to the design process.

PROBLEM-SOLVING IN SCHIZOPHRENIA - A SPECIFIC DEFICIT IN PLANNING ABILITY

The study investigated problem solving ability in schizophrenia. Thirty DSM-IIIR schizophrenic patients and 27 matched normal controls were tested on the Three-Dimensional Computerised Tower of London Test (3-D CTL Test) (Morris et al., 1993). The patients took significantly more moves to solve a series of problems and solved significantly fewer problems in the predetermined minimum number of moves. The patients response times, as measured using a control version of the task (the 3-D CTL Control), were longer than those of the controls. However, when latencies were adjusted to take into account the slower responses overall, the patients planning times were not significantly increased. Inaccurate planning, as defined by taking more moves, did not correlate with either positive or negative symptoms, but the response times tended to be longer in patients who had more negative symptoms. The findings suggest that there is a deficit in problem solving activity in schizophrenia that may be associated with translating 'willed intentions' into action, independent of slower motor speed.

A comparison of the application of STOPP/START to patients' drug lists with and without clinical information

Background A European screening tool (STOPP/START) has been formulated to identify the prescribing of potentially inappropriate medicines (PIMs) and potential prescribing omissions (PPOs). Pharmacists working in community pharmacies could use STOPP/START as a guide to conducting medication use reviews; however, community pharmacists do not routinely have access to patients' clinical records. Objective To compare the PIM and PPO detection rates from application of the STOPP/START criteria to patients' medication details alone with the detection rates from application of STOPP/START to information on patients' medications combined with clinical information. Setting Community Pharmacy. Method Three pharmacists applied STOPP/START to 250 patient medication lists, containing information regarding dose, frequency and duration of treatment. The PIMs and PPOs identified by each pharmacist were compared with those identified by consensus agreement of two other pharmacists, who applied STOPP/START criteria using patients' full clinical records. Main outcome measure The main outcome measures were: (1) PIM and PPO detection rates among pharmacists with access to patients' clinical information compared to PIM and PPO detection rates among pharmacists using patients' medication information only, and (2) the levels of agreement (calculated using Cohen's kappa statistic (k)) for the three most commonly identified PIMs and PPOs. Results Pharmacists with access to patients' clinical records identified significantly fewer PIMs than pharmacists without (p = 0.002). The three most commonly identified PIMs were benzodiazepines, proton pump inhibitors and duplicate drug classes, with kappa (k) statistic agreement ranges of 0.87-0.97, 0.60-0.68 and 0.39-0.85 respectively. PPOs were identified more often (p 

'The performative surprise': parody, documentary and critique

Can parody help us to 're-imagine' the organizations and institutions we live with (Du Gay 2007, 13)? Or, like many forms of critique, does parody risk being incorporated: becoming part of the power it aims to make fun of? In this paper, drawing on Judith Butler's work, I argue that certain circumstances enable parody to destabilize hegemonic, taken-for-granted institutions (Butler 1990). I explore these ideas through a reading of the Yes Men documentary (Tartan Video 2005). This film features a series of humorous representations of the World Trade Organization (WTO). I show how these act to denaturalize and effectively critique this dominant force in global trade. This paper discusses the value of parody for helping us to re-think and re-make particular institutions and organizations. In doing so, I point to the importance of creating a spectacle in which parody can travel beyond its immediate location, so that it can reach ever newer audiences with its 'performative surprise' (Butler 1990, xxvi). I suggest that the rise of the Internet and inexpensive documentary techniques offer interesting new ways for achieving this.
