Quantifying search dog effectiveness in a terrestrial search and rescue environment

This work represents a first attempt to quantify and understand levels of performance in lowland search dogs, and these results need to be understood within that context. A repeatable experimental framework has been demonstrated and provides a foundation for further work in this area

Global entanglement in multiparticle systems

We define a polynomial measure of multiparticle entanglement which is scalable, i.e., which applies to any number of spin-1/2 particles. By evaluating it for three particle states, for eigenstates of the one dimensional Heisenberg antiferromagnet and on quantum error correcting code subspaces, we illustrate the extent to which it quantifies global entanglement. We also apply it to track the evolution of entanglement during a quantum computation.Comment: 9 pages, plain TeX, 1 PostScript figure included with epsf.tex (ignore the under/overfull \vbox error messages); for related work see http://math.ucsd.edu/~dmeyer/research.html or http://www.math.ucsd.edu/~nwallach

The Celtic Sea area (Functional Units 19-22) supports a large multi-national targeted Nephrops fishery mainly using otter trawls and yielding landings in the region of ~6,000 t annually over the last decade (ICES, 2011). Nephrops spend a great deal of time in their burrows and their emergence behaviour is influenced many factors; time of year, light intensity and tidal strength. Underwater television surveys and assessment methodologies have been developed to provide a fishery independent estimate of stock size, exploitation status and catch advice (ICES, 2009 & 2011).This is the sixth in a time series of UWTV surveys in the Celtic Sea carried out by the Marine Institute, Ireland. The 2011 survey was multi disciplinary in nature and this report details the final UWTV results of the 2011 survey and also documents other data collected during the survey

Incongruence between nurses\u27 and patients\u27 understandings and expectations of rehabilitation

Aims and objectives. To explore nurses\u27 understandings and expectations of rehabilitation and nurses\u27 perceptions of patients\u27 understandings and expectations of rehabilitation.Background. Within the context of a broadening appreciation of the benefits of rehabilitation, interest in the nature of rehabilitation is growing. Some believe that rehabilitation services do not adequately meet the needs of patients. Others are interested in the readiness of patients to participate in rehabilitation.Design. Qualitative.Method. Grounded theory using data collected during interviews with nurses in five inpatient rehabilitation units and during observation of the nurses\u27 everyday practice.Findings. According to nurses working in inpatient rehabilitation units, there is a marked incongruence between nurses\u27 understandings and expectations of rehabilitation and what they perceive patients to understand and expect.Conclusion. Given these different understandings, an important nursing role is the education of patients about the nature of rehabilitation and how to optimise their rehabilitation.Relevance to clinical practice. Before patients are transferred to rehabilitation, the purpose and nature of rehabilitation, in particular the roles of patients and nurses, needs to be explained to them. The understandings of rehabilitation that nurses in this study possessed provide a framework for the design of education materials and orientation programmes that inform patients (and their families) about rehabilitation. In addition, reinforcement of the differences between acute care and rehabilitation will assist patients new to rehabilitation to understand the central role that they themselves can play in their recovery.<br /

Obstacles to public health that even pandemics cannot overcome : the politics of Covid-19 on the island of Ireland

The relationship between politics and public health is increasingly evident as governments throughout the world vary in their acceptance and implementation of technical guidance in the response to the SARS-CoV-2 pandemic. This paper reports a qualitative study of public health policies for Covid-19 in Northern Ireland (NI) and the Republic of Ireland (RoI) across a timeline emphasising the first wave of the pandemic (February to June 2020). Inter-jurisdictional commitments for health as contained in the Good Friday Agreement provide a framework for cooperation and coordination of population health on the island of Ireland. This study of north-south cooperation in the response to Covid-19 applies ten indicators from the Oxford Covid-19 Government Response Tracker (OxCGRT) codebook to establish if cooperation and policy alignment of key public health measures are evident in the Northern Ireland Assembly and Government of Ireland responses. The study concludes that notwithstanding the historical and constitutional obstacles to an all-island response to Covid-19, there is evidence of significant public health policy alignment brought about through ongoing dialogue and cooperation between the health administrations in each jurisdiction over the course of the first wave of the pandemic

The twilight of the Liberal Social Contract? On the Reception of Rawlsian Political Liberalism

This chapter discusses the Rawlsian project of public reason, or public justification-based 'political' liberalism, and its reception. After a brief philosophical rather than philological reconstruction of the project, the chapter revolves around a distinction between idealist and realist responses to it. Focusing on political liberalism’s critical reception illuminates an overarching question: was Rawls’s revival of a contractualist approach to liberal legitimacy a fruitful move for liberalism and/or the social contract tradition? The last section contains a largely negative answer to that question. Nonetheless the chapter's conclusion shows that the research programme of political liberalism provided and continues to provide illuminating insights into the limitations of liberal contractualism, especially under conditions of persistent and radical diversity. The programme is, however, less receptive to challenges to do with the relative decline of the power of modern states

Adjuvant-specific regulation of long-term antibody responses by ZBTB20

The duration of antibody production by long-lived plasma cells varies with the type of immunization, but the basis for these differences is unknown. We demonstrate that plasma cells formed in response to the same immunogen engage distinct survival programs depending on the adjuvant. After alum-adjuvanted immunization, antigen-specific bone marrow plasma cells deficient in the transcription factor ZBTB20 failed to accumulate over time, leading to a progressive loss of antibody production relative to wild-type controls. Fetal liver reconstitution experiments demonstrated that the requirement for ZBTB20 was B cell intrinsic. No defects were observed in germinal center numbers, affinity maturation, or plasma cell formation or proliferation in ZBTB20-deficient chimeras. However, ZBTB20-deficient plasma cells expressed reduced levels of MCL1 relative to wild-type controls, and transgenic expression of BCL2 increased serum antibody titers. These data indicate a role for ZBTB20 in promoting survival in plasma cells. Strikingly, adjuvants that activate TLR2 and TLR4 restored long-term antibody production in ZBTB20-deficient chimeras through the induction of compensatory survival programs in plasma cells. Thus, distinct lifespans are imprinted in plasma cells as they are formed, depending on the primary activation conditions. The durability of vaccines may accordingly be improved through the selection of appropriate adjuvants

Clinical effectiveness, cost-effectiveness and acceptability of low-intensity interventions in the management of obsessive–compulsive disorder: the Obsessive–Compulsive Treatment Efficacy randomised controlled Trial (OCTET)

Background: The Obsessive–Compulsive Treatment Efficacy randomised controlled Trial emerged from a research recommendation in National Institute for Health and Care Excellence obsessive–compulsive disorder (OCD) guidelines, which specified the need to evaluate cognitive–behavioural therapy (CBT) treatment intensity formats. Objectives: To determine the clinical effectiveness and cost-effectiveness of two low-intensity CBT interventions [supported computerised cognitive–behavioural therapy (cCBT) and guided self-help]: (1) compared with waiting list for high-intensity CBT in adults with OCD at 3 months; and (2) plus high-intensity CBT compared with waiting list plus high-intensity CBT in adults with OCD at 12 months. To determine patient and professional acceptability of low-intensity CBT interventions. Design: A three-arm, multicentre, randomised controlled trial. Setting: Improving Access to Psychological Therapies services and primary/secondary care mental health services in 15 NHS trusts. Participants: Patients aged ≥ 18 years meeting Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition criteria for OCD, on a waiting list for high-intensity CBT and scoring ≥ 16 on the Yale–Brown Obsessive Compulsive Scale (indicative of at least moderate severity OCD) and able to read English. Interventions: Participants were randomised to (1) supported cCBT, (2) guided self-help or (3) a waiting list for high-intensity CBT. Main outcome measures: The primary outcome was OCD symptoms using the Yale–Brown Obsessive Compulsive Scale – Observer Rated. Results: Patients were recruited from 14 NHS trusts between February 2011 and May 2014. Follow-up data collection was complete by May 2015. There were 475 patients randomised: supported cCBT (n = 158); guided self-help (n = 158) and waiting list for high-intensity CBT (n = 159). Two patients were excluded post randomisation (one supported cCBT and one waiting list for high-intensity CBT); therefore, data were analysed for 473 patients. In the short term, prior to accessing high-intensity CBT, guided self-help demonstrated statistically significant benefits over waiting list, but these benefits did not meet the prespecified criterion for clinical significance [adjusted mean difference –1.91, 95% confidence interval (CI) –3.27 to –0.55; p = 0.006]. Supported cCBT did not demonstrate any significant benefit (adjusted mean difference –0.71, 95% CI –2.12 to 0.70). In the longer term, access to guided self-help and supported cCBT, prior to high-intensity CBT, did not lead to differences in outcomes compared with access to high-intensity CBT alone. Access to guided self-help and supported cCBT led to significant reductions in the uptake of high-intensity CBT; this did not seem to compromise patient outcomes at 12 months. Taking a decision-making approach, which focuses on which decision has a higher probability of being cost-effective, rather than the statistical significance of the results, there was little evidence that supported cCBT and guided self-help are cost-effective at the 3-month follow-up compared with a waiting list. However, by the 12-month follow-up, data suggested a greater probability of guided self-help being cost-effective than a waiting list from the health- and social-care perspective (60%) and the societal perspective (80%), and of supported cCBT being cost-effective compared with a waiting list from both perspectives (70%). Qualitative interviews found that guided self-help was more acceptable to patients than supported cCBT. Professionals acknowledged the advantages of low intensity interventions at a population level. No adverse events occurred during the trial that were deemed to be suspected or unexpected serious events. Limitations: A significant issue in the interpretation of the results concerns the high level of access to high-intensity CBT during the waiting list period. Conclusions: Although low-intensity interventions are not associated with clinically significant improvements in OCD symptoms, economic analysis over 12 months suggests that low-intensity interventions are cost-effective and may have an important role in OCD care pathways. Further research to enhance the clinical effectiveness of these interventions may be warranted, alongside research on how best to incorporate them into care pathways
