On the local Langlands correspondence for non-tempered representations
No full textLet G be a reductive p-adic group. We study how a local Langlands correspondence for irreducible tempered G-representations can be extended to a local Langlands correspondence for all irreducible smooth representations of G. We prove that, under a natural condition involving compatibility with unramified twists, this is possible in a canonical way. To this end we introduce analytic R-groups associated to non-tempered essentially square-integrable representations of Levi subgroups of G. We establish the basic properties of these new R-groups, which generalize Knapp–Stein R-groups

Effect and Improvement Areas for Port State Control Inspections to Decrease the Probability of Casualty
No full textThis report is the fourth part of a PhD project called "The Econometrics of Maritime Safety – Recommendations to Enhance Safety at Sea" and is based on 183,000 port state control inspections and 11,700 casualties from various data sources. Its overall objective is to provide recommendations to improve safety at sea. The fourth part looks into measuring the effect of inspections on the probability of casualty on either seriousness or casualty first event to show the differences across the regimes. It further gives a link of casualties that were found during inspections with either the seriousness of casualties and casualty first events which reveals three areas of improvement possibilities to potentially decrease the probability of a casualty – the ISM code, machinery and equipment and ship and cargo operations.maritime safety;correspondence analysis;binary logistic regression;probability of casualty;improvement;Port State Control Effectiveness;casualty first events;detention;port state control deficiences;target factor

Client Socio-Demographic and Service Receipt Inventory--European Version: development of an instrument for international research. EPSILON Study 5. European Psychiatric Services: Inputs Linked to Outcome Domains and Needs.
No full textBACKGROUND: Cross-cultural comparison of mental health service utilisation and costs is complicated by the heterogeneity of service systems. For data to be locally meaningful yet internationally comparable, a carefully constructed approach to its collection is required. AIMS: To develop a research method and instrument for the collection of data on the service utilisation and related characteristics of people with mental disorders, as the basis for calculating the costs of care. METHOD: Various approaches to the collection of service use data and key stages of instrument development were identified in order to select the most appropriate methods. RESULTS: Based on previous work, and following translation and cross-cultural validation, an instrument was developed: the Client Socio-Demographic and Service Receipt Inventory--European Version (CSSRI-EU). This was subsequently administered to 404 people with schizophrenia across five countries. CONCLUSION: The CSSRI-EU provides a standardised yet adaptable method for collating service receipt and associated data alongside assessment of patient outcomes
Isolation of 10 cyclosporine metabolites from human bile
No full textTen metabolites of cyclosporine were isolated from the ethyl ether extract of bile from four liver transplant patients receiving cyclosporine. Two of the metabolites were unique and previously unidentified. Liquid-liquid partitioning into diethyl ether with subsequent defatting with n-hexane was used for the initial extraction form bile. Separation of the individual metabolites (A-J) was performed using a Sephadex LH-20 column and a gradient high performance liquid chromatographic method. The molecular weights of the isolated metabolites were determined by fast atom bombardment/mass spectrometry. Gas chromatography with mass spectrometic amino acid analysis was also used to identify the amino acid composition and the hydroxylation position of metabolites A, B, C, D, and G. Proton nuclear magnetic resonance spectra were utilized to disinguish the chemical shifts of N-CH3 singlets and NH doublets of metabolites A, B, C, and D. Metabolites A, E, F, H, I, and J were reported previously in human urine and animal bile. Metabolites C and D are dihydroxylated compounds which cannot be clearly described as previously isolated compounds. Metabolites B and G are novel metabolites with a mass fragment which corresponded to a loss of 131 Da from the protonated molecular ion (MH+) in the fast atom bombardment/mass spectrometry, suggesting that the double bond in amino acid 1 has been modified. Metabolites B and G were primarily isolated from the bile of one of the liver transplant patients which contained abnormally high concentrations of these two metabolites. The method described is an efficient procedure for isolating milligram quantities of the major metabolites with greater than 95% purity
New insights into hepatitis C
No full textHepatitis C infection is characterised by three key features, which are the consequence of a complex interaction between genetic determinants of immune and other host factors and viral characteristics: 1. A high rate of viral persistence after acute infection resulting from a combination of weak T cell responsiveness and specific viral mechanisms of immune escape. 2. Marked interindividual variability in end-organ damage (fibrosis and cirrhosis), probably due to host genetic polymorphisms in genes governing the immune response and fibrosis pathways in addition to viral pathogenicity factors. 3. Significant resistance to antiviral therapies. Viral mechanisms of antiviral resistance parallel those of viral persistence, and include the intriguing possibility that hepatitis C may infect immunologically privileged sites such as the central nervous system.</p
