Playing the 'Blame Game': Accounting and the construction of disruptive behaviour in family interviews

Systemic conceptualisations suggest that family processes which involve blaming and holding the child accountable for their behaviour play an important role in the maintenance of disruptive behaviour problems. Discourse analytic work in family therapy settings has shown that accountability for the family’s reported problems is a key concern for family members. This study used a conversation analytic (CA) approach to examine family members’ accounts of child disruptive behaviour. The two participating families were both engaged in family therapy for disruptive behaviour problems. Each family participated in a family interview which was recorded and transcribed according to CA principles. The analysis focused on the discursive organisation of accounts, as well as how these accounts were constructed to actively manage accountability during the interviews. Accounts were organised into a threepart structure consisting of a ‘statement of causality’, ‘warrant’ and ‘formulation’. Three strategies for managing accountability were identified: ‘objectifying’, ‘normalising’ and ‘systematic vagueness’. The analytic findings are discussed in terms of their relevance to systemic theory and practice

SimArray: a user-friendly and user-configurable microarray design tool.

BACKGROUND: Microarrays were first developed to assess gene expression but are now also used to map protein-binding sites and to assess allelic variation between individuals. Regardless of the intended application, efficient production and appropriate array design are key determinants of experimental success. Inefficient production can make larger-scale studies prohibitively expensive, whereas poor array design makes normalisation and data analysis problematic. RESULTS: We have developed a user-friendly tool, SimArray, which generates a randomised spot layout, computes a maximum meta-grid area, and estimates the print time, in response to user-specified design decisions. Selected parameters include: the number of probes to be printed; the microtitre plate format; the printing pin configuration, and the achievable spot density. SimArray is compatible with all current robotic spotters that employ 96-, 384- or 1536-well microtitre plates, and can be configured to reflect most production environments. Print time and maximum meta-grid area estimates facilitate evaluation of each array design for its suitability. Randomisation of the spot layout facilitates correction of systematic biases by normalisation. CONCLUSION: SimArray is intended to help both established researchers and those new to the microarray field to develop microarray designs with randomised spot layouts that are compatible with their specific production environment.

The recovery movement and its implications for policy, commissioning and practice

While a recovery approach is widespread and relatively unquestioned in the USA, its implementation in the UK and to a lesser extent in Australia has provoked a number of questions about what this means in practice and what some of the implications are for treatment. This is particularly important as there is growing interest in recovery in Western Europe with policy recognition in Belgium and the Netherlands, and increased interest in research issues around recovery. What this article sets out to do is to discuss the implications of a recovery model for commissioning and treatment systems, with a focus on where recovery approaches sit and what they can offer in terms of added value to treatment approaches

Viral respiratory infections at the Hajj: comparison between UK and Saudi pilgrims

ABSTRACTA high incidence of respiratory infection, including influenza, has been reported at the Hajj in Mecca, Saudi Arabia. Reported rates of influenza have been higher among UK than among domestic pilgrims, but this could be explained by methodological differences among studies. Accordingly, the present study compared the frequencies of respiratory viruses among UK and Saudi pilgrims using the same study design. Pilgrims with upper respiratory tract symptoms were recruited from Mecca and the neighbouring valley Mina during the Hajj 2006. Nasal swabs were used for point-of-care influenza testing and real-time RT-PCR (rtRT-PCR) tests for influenza virus, rhinovirus, parainfluenza virus, adenovirus, human metapneumovirus and respiratory syncytial virus. Of 260 pilgrims investigated, 150 were from the UK and 110 were Saudi; of these, 38 (25%) UK pilgrims and 14 (13%) Saudi pilgrims had respiratory infections detectable by rtRT-PCR (p 0.01). In the UK group, there were 19 (13%) cases of rhinovirus infection, 15 (10%) cases of influenza virus infection, two (1%) cases of dual infections with influenza virus and rhinovirus, one (3%) case of parainfluenza virus infection, and one (1%) case of respiratory syncytial virus infection. Fifty-six (37%) UK pilgrims had been vaccinated against influenza virus, with the rates of influenza in the vaccinated and unvaccinated group being 7% and 14%, respectively (p 0.19). In the Saudi group, there were three (3%) cases of rhinovirus infection and 11 (10%) cases of influenza. Only four (4%) Saudi pilgrims had been vaccinated against influenza virus, and none of these was infected with influenza virus. Overall, a significantly higher proportion of the UK pilgrims had detectable respiratory infections (25% vs. 13%, p 0.01). Influenza rates were similar in both groups, but the reported rates of influenza vaccination differed

Allele Copy Number and Underlying Pathology Are Associated with Subclinical Severity in Equine Type 1 Polysaccharide Storage Myopathy (PSSM1)

Equine type 1 polysaccharide storage myopathy (PSSM1), a common glycogenosis associated with an R309H founder mutation in the glycogen synthase 1 gene (GYS1), shares pathological features with several human myopathies. In common with related human disorders, the pathogenesis remains unclear in particular, the marked phenotypic variability between affected animals. Given that affected animals accumulate glycogen and alpha-crystalline polysaccharide within their muscles, it is possible that physical disruption associated with the presence of this material could exacerbate the phenotype. The aim of this study was to compare the histopathological changes in horses with PSSM1, and specifically, to investigate the hypothesis that the severity of underlying pathology, (e.g. vacuolation and inclusion formation) would (1) be higher in homozygotes than heterozygotes and (2) correlate with clinical severity. Resting and post-exercise plasma creatine kinase (CK) and aspartate aminotransferase (AST) enzyme activity measurements and muscle pathology were assessed in matched cohorts of PSSM1 homozygotes, heterozygotes or control horses. Median (interquartile range (IR)) resting CK activities were 364 (332–764) U/L for homozygotes, 301 (222–377) U/L for heterozygotes and 260 (216–320) U/L for controls, and mean (+/− SD) AST activity for homozygotes were 502 (+/116) U/L, for heterozygotes, 357 (+/−92) U/L and for controls, 311 (+/−64) U/L and were significantly different between groups (P = 0.04 and P = 0.01 respectively). Resting plasma AST activity was significantly associated with the severity of subsarcolemmal vacuolation (rho = 0.816; P = 0.01) and cytoplasmic inclusions (rho = 0.766; P = 0.01). There were fewer type 2× and more type 2a muscle fibres in PSSM1-affected horses. Our results indicate that PSSM1 has incomplete dominance. Furthermore, the association between plasma muscle enzyme activity and severity of underlying pathology suggests that physical disruption of myofibres may contribute to the myopathic phenotype. This work provides insight into PSSM1 pathogenesis and has implications for related human glycogenoses

Natural Wormholes as Gravitational Lenses

Visser has suggested traversable 3-dimensional wormholes that could plausibly form naturally during Big Bang inflation. A wormhole mouth embedded in high mass density might accrete mass, giving the other mouth a net *negative* mass of unusual gravitational properties. The lensing of such a gravitationally negative anomalous compact halo object (GNACHO) will enhance background stars with a time profile that is observable and qualitatively different from that recently observed for massive compact halo objects (MACHOs) of positive mass. We recommend that MACHO search data be analyzed for GNACHOs.Comment: 4 pages; plus 4 figures; ReV_TeX 3.0; DOE/ER/40537-001/NPL94-07-01

Evaluation of Jobsite Cylinder Curing Practices for the Alabama Concrete Industry

The effect of initial curing temperature and duration on the 28-day compressive strength of concrete was experimentally evaluated. Concrete cylinders were cured at six initial curing temperatures (60, 68, 78, 84, 90, and 100 \u2070F) for three different initial curing durations (24, 48, and 72 hours). After the initial curing duration was complete, the cylinders were moved to final curing in a moist cure room that maintained a temperature of 73.5 \ub1 3.5 \ub0F until compressive strength testing at 28 days. Eight different concretes were produced at elevated temperatures to simulate summer placement conditions. The results confirm that as the initial curing temperature increases, the 28-day concrete compressive strength decreases. When cured at an initial curing temperature of 100 \u2070F, a maximum reduction of 23% in the 28-day compressive strength occurred. It is critical to maintain initial curing temperatures ranging from 60 to 80 \u2070F because then the change in 28-day strength remains within the acceptable ranges. When the initial curing temperature ranges from 60 to 80 \u2070F, then increasing the initial curing duration from 48 hour to 72 hour does not significantly affect the 28-day concrete compressive strength. The maximum initial curing duration can thus be increased from 48 to 72 hours, which will permit cylinders made on Fridays to be transported to their final curing location on Mondays

VivaxGEN: An open access platform for comparative analysis of short tandem repeat genotyping data in Plasmodium vivax populations.

BACKGROUND: The control and elimination of Plasmodium vivax will require a better understanding of its transmission dynamics, through the application of genotyping and population genetics analyses. This paper describes VivaxGEN (http://vivaxgen.menzies.edu.au), a web-based platform that has been developed to support P. vivax short tandem repeat data sharing and comparative analyses. RESULTS: The VivaxGEN platform provides a repository for raw data generated by capillary electrophoresis (FSA files), with fragment analysis and standardized allele calling tools. The query system of the platform enables users to filter, select and differentiate samples and alleles based on their specified criteria. Key population genetic analyses are supported including measures of population differentiation (FST), expected heterozygosity (HE), linkage disequilibrium (IAS), neighbor-joining analysis and Principal Coordinate Analysis. Datasets can also be formatted and exported for application in commonly used population genetic software including GENEPOP, Arlequin and STRUCTURE. To date, data from 10 countries, including 5 publicly available data sets have been shared with VivaxGEN. CONCLUSIONS: VivaxGEN is well placed to facilitate regional overviews of P. vivax transmission dynamics in different endemic settings and capable to be adapted for similar genetic studies of P. falciparum and other organisms

No association between the Plasmodium vivax crt-o MS334 or In9pvcrt polymorphisms and chloroquine failure in a pre-elimination clinical cohort from Malaysia with a large clonal expansion

Increasing reports of resistance to a frontline malaria blood-stage treatment, chloroquine (CQ), raises concerns for the elimination of Plasmodium vivax. The absence of an effective molecular marker of CQ resistance in P. vivax greatly constrains surveillance of this emerging threat. A recent genetic cross between CQ sensitive (CQS) and CQ resistant (CQR) NIH-1993 strains of P. vivax linked a moderate CQR phenotype with two candidate markers in P. vivax CQ resistance transporter gene (pvcrt-o): MS334 and In9pvcrt. Longer TGAAGH motif lengths at MS334 were associated with CQ resistance, as were shorter motifs at the In9pvcrt locus. In this study, high-grade CQR clinical isolates of P. vivax from a low endemic setting in Malaysia were used to investigate the association between the MS334 and In9pvcrt variants and treatment efficacy. Among a total of 49 independent monoclonal P. vivax isolates assessed, high-quality MS334 and In9pvcrt sequences could be derived from 30 (61%) and 23 (47%), respectively. Five MS334 and six In9pvcrt alleles were observed, with allele frequencies ranging from 2 to 76% and 3 to 71%, respectively. None of the clinical isolates had the same variant as the NIH-1993 CQR strain, and none of the variants were associated with CQ treatment failure (all P > 0.05). Multi-locus genotypes (MLGs) at 9 neutral microsatellites revealed a predominant P. vivax strain (MLG6) accounting for 52% of Day 0 infections. The MLG6 strain comprised equal proportions of CQS and CQR infections. Our study reveals complexity in the genetic basis of CQ resistance in the Malaysian P. vivax pre-elimination setting and suggests that the proposed pvcrt-o MS334 and In9pvcrt markers are not reliable markers of CQ treatment efficacy in this setting. Further studies are needed in other endemic settings, applying hypothesis-free genome-wide approaches, and functional approaches to understand the biological impact of the TGAAGH repeats linked to CQ response in a cross are warranted to comprehend and track CQR P. vivax
