Connectivity of tropicalizations

We show that the tropicalization of an irreducible variety over a complete or algebraically closed valued field is connected through codimension 1, giving an affirmative answer in all characteristics to a question posed by Einsiedler, Lind, and Thomas in 2003.Comment: 7 page

Baryon chiral perturbation theory

We provide a short introduction to the one-nucleon sector of chiral perturbation theory and address the issue of power counting and renormalization. We discuss the infrared regularization and the extended on-mass-shell scheme. Both allow for the inclusion of further degrees of freedom beyond pions and nucleons and the application to higher-loop calculations. As applications we consider the chiral expansion of the nucleon mass to order ${\cal O}(q^6)$ and the inclusion of vector and axial-vector mesons in the calculation of nucleon form factors. Finally, we address the complex-mass scheme for describing unstable particles in effective field theory.Comment: 13 pages, 8 figures, invited talk given at the Third International Conference on Hadron Physics, TROIA'11, 22 - 25 August 2011, Canakkale, Turke

Agriculture modifies the seasonal decline of breeding success in a tropical wild bird population

1.Habitat conversion for agriculture is a major driver of biodiversity loss, but our understanding of the demographic processes involved remains poor. We typically investigate the impacts of agriculture in isolation even though populations are likely to experience multiple, concurrent changes in the environment (e.g. land and climate change). Drivers of environmental change may interact to affect demography but the mechanisms have yet to be explored fully in wild populations. 2.Here, we investigate the mechanisms linking agricultural land-use with breeding success using long-term data for the formerly Critically Endangered Mauritius kestrel Falco punctatus; a tropical forest specialist that also occupies agricultural habitats. We specifically focused on the relationship between breeding success, agriculture and the timing of breeding because the latter is sensitive to changes in climatic conditions (spring rainfall), and enables us to explore the interactive effects of different (land and climate) drivers of environmental change. 3.Breeding success, measured as egg survival to fledging, declines seasonally in this population, but we found that the rate of this decline became increasingly rapid as the area of agriculture around a nest site increased. If the relationship between breeding success and agriculture was used in isolation to estimate the demographic impact of agriculture it would significantly under-estimate breeding success in dry (early) springs, and over-estimate breeding success in wet (late) springs. 4.Analysis of prey delivered to nests suggests that the relationship between breeding success and agriculture might be due, in part, to spatial variation in the availability of native, arboreal geckos. 5.Synthesis and applications. Agriculture modifies the seasonal decline in breeding success in this population. As springs are becoming wetter in our study area and since the kestrels breed later in wetter springs, the impact of agriculture on breeding success will become worse over time. Our results suggest that forest restoration designed to reduce the detrimental impacts of agriculture on breeding may also help reduce the detrimental effects of breeding late due to wetter springs. Our results therefore highlight the importance of considering the interactive effects of environmental change when managing wild populations

A meta-analysis of transdiagnostic cognitive behavioural therapy in the treatment of child and young person anxiety disorders

Background: Previous meta-analyses of cognitive-behavioural therapy (CBT) for children and young people with anxiety disorders have not considered the efficacy of transdiagnostic CBT for the remission of childhood anxiety. Aim: To provide a meta-analysis on the efficacy of transdiagnostic CBT for children and young people with anxiety disorders. Methods: The analysis included randomized controlled trials using transdiagnostic CBT for children and young people formally diagnosed with an anxiety disorder. An electronic search was conducted using the following databases: ASSIA, Cochrane Controlled Trials Register, Current Controlled Trials, Medline, PsycArticles, PsychInfo, and Web of Knowledge. The search terms included “anxiety disorder(s)”, “anxi∗”, “cognitive behavio∗, “CBT”, “child∗”, “children”, “paediatric”, “adolescent(s)”, “adolescence”, “youth” and “young pe∗”. The studies identified from this search were screened against the inclusion and exclusion criteria, and 20 studies were identified as appropriate for inclusion in the current meta-analysis. Pre- and posttreatment (or control period) data were used for analysis. Results: Findings indicated significantly greater odds of anxiety remission from pre- to posttreatment for those engaged in the transdiagnostic CBT intervention compared with those in the control group, with children in the treatment condition 9.15 times more likely to recover from their anxiety diagnosis than children in the control group. Risk of bias was not correlated with study effect sizes. Conclusions: Transdiagnostic CBT seems effective in reducing symptoms of anxiety in children and young people. Further research is required to investigate the efficacy of CBT for children under the age of 6

Development of an intervention to support parents receiving treatment in psychiatric inpatient hospital using participatory design methods

IntroductionWhen parents of dependent children are treated in psychiatric inpatient hospital, it typically involves separation of parent and child for the duration of treatment, which can be highly distressing to the dyad and can result in disruption to the parent-child relationship. Parents who have experienced hospitalisation have expressed a desire for their parenting identity to be recognized and appropriately engaged with during their treatment. This recognition includes provision of interventions which support them as parents to limit the impact of their mental health on their children. The current study, the first of its kind known to have taken place, details a collaborative intervention development project for parents receiving inpatient care.MethodsThe current study, the first of its kind known to have taken place, details a collaborative intervention development project for parents receiving inpatient care. This project involved the adaptation and extension of a prior parenting-focused course for parents high in anxiety to meet the needs of parents being treated in inpatient settings. In the first two stages of the three-phase project, patients, carers and mental health practitioners contributed to the revision and delivery plan for the course including developing new content for the intervention. In the final stage, which took the form of a participatory evaluation, the intervention was delivered to 11 parents receiving inpatient treatment who then provided extensive feedback. A series of iterative adaptations to the intervention were made in response to this feedback alongside stakeholder input.ResultsThe final intervention comprises five modules focused on exploring the experience of parents alongside specific learning and skills orientated toward boosting their connection with their children during hospitalisation and in readiness for discharge. Preliminary feedback from patients and ward staff has been positive and the process of delivering the project on inpatient wards was associated with no increase in negative clinical outcomes.DiscussionThe successful development of a targeted intervention within inpatient psychiatric units offers a signal that parents treated in this setting welcome the opportunity to be supported in their parenting role. As the first known UK intervention of its kind to be developed in partnership with patients, ward staff and management, it is specifically tailored to the context and needs of this group with the potential to be delivered by a range of health professionals in this setting

Adult mental health service engagement with patients who are parents: evidence from 15 English mental health trusts

Objectives Ascertaining whether mental health service users have children is a clinical requirement in UK health services, and acknowledgement of a patient’s parenting role is necessary to enable engagement with their parenting experience and to facilitate support, both of which are associated with improved outcomes for the parent–child dyad. The current study sought to investigate the practice of mental health practitioners working in UK adult mental health services with regard to the following: Ascertaining whether patients have children; engagement with the parenting role of patients; engagement with the construct of ‘think patient as parent’. Methods Self-report online/paper survey of 1105 multi-disciplinary adult mental health practitioners working in 15 mental health trusts in England. Results A quarter of adult mental health practitioners did not routinely ascertain whether patients had dependent children. Less than half of practitioners engaged with the parenting experience or the potential impact of parental mental health on children. Conclusions The parenting role of patients is not routinely captured by large numbers of practitioners working in adult mental health settings. This is despite it being a mandatory requirement and an integral component of the systematic care of the adult, and preventative care for the offspring. Failure to engage with patients who are parents is a missed opportunity with profound downstream public health implications. The practice deficits identified in this study should be viewed in terms of broader structural failures to address the intergenerational transmission of poor mental health. Practitioner points -Some parents who have mental health difficulties may struggle to provide appropriate and effective care to their children. The parenting role can also exacerbate mental health difficulties. -Identification of dependent children is a mandatory component of adult mental health clinical practice and is necessary to understand a parent’s support needs. -A quarter of adult mental health practitioners are failing to do so. A missed opportunity to engage with the support needs of the parent–child dyad

A new parenting-based group intervention for young anxious children: results of a randomized controlled trial

Objective Despite recent advances, there are still no interventions that have been developed for the specific treatment of young children who have anxiety disorders. This study examined the impact of a new, cognitive–behaviorally based parenting intervention on anxiety symptoms. Method Families of 74 anxious children (aged 9 years or less) took part in a randomized controlled trial, which compared the new 10-session, group-format intervention with a wait-list control condition. Outcome measures included blinded diagnostic interview and self-reports from parents and children. Results Intention-to-treat analyses indicated that children whose parent(s) received the intervention were significantly less anxious at the end of the study than those in the control condition. Specifically, 57% of those receiving the new intervention were free of their primary disorder, compared with 15% in the control condition. Moreover, 32% of treated children were free of any anxiety diagnosis at the end of the treatment period, compared with 6% of those in the control group. Treatment gains were maintained at 12-month follow-up. Conclusions This new parenting-based intervention may represent an advance in the treatment of this previously neglected group.
