Nature Communications, 11(1), (2020): 678, doi:10.1038/s41467-020-14423-9.Tropical cyclones are one of the most destructive natural hazards and much of the damage and casualties they cause are flood-related. Accurate characterization and prediction of total water levels during extreme storms is necessary to minimize coastal impacts. While meteotsunamis are known to influence water levels and to produce severe consequences, their impacts during tropical cyclones are underappreciated. This study demonstrates that meteotsunami waves commonly occur during tropical cyclones, and that they can contribute significantly to total water levels. We use an idealized coupled ocean–atmosphere–wave numerical model to analyze tropical cyclone-induced meteotsunami generation and propagation mechanisms. We show that the most extreme meteotsunami events are triggered by inherent features of the structure of tropical cyclones: inner and outer spiral rainbands. While outer distant spiral rainbands produce single-peak meteotsunami waves, inner spiral rainbands trigger longer lasting wave trains on the front side of the tropical cyclones.We thank all the developers of COAWST, ROMS, WRF, and SWAN models.

Supporting carers of people diagnosed with schizophrenia: evaluating change in nursing practice following training

<i>Background</i>: United Kingdom legislation and clinical standards for schizophrenia challenge nurses to re-examine the support that they provide to carers. Nurses are in a key position to provide this support but may lack the necessary skills to do so. The training programme evaluated in the present study aimed to address this problem. <i>Study</i> <i>aim</i>: To evaluate change in clinical practice brought about by post-registration training for mental health nurses in supporting carers of people diagnosed with schizophrenia. <i>Design/methods</i>: The study was undertaken in collaboration between the Universities of Dundee and Glasgow, and Tayside National Health Service (NHS) Trust (Scotland). Respondents were nine nurses who completed training and then delivered a planned programme of support to carers. Data on nursing practice were gathered through semi-structured interviews with nurses before training and after providing support. Following the support intervention, carers also commented on the nurses' practice. <i>Findings</i>: Eight of the nine nurses reported changes in practice in five key areas: They built collaborative relationships with carers, developed a carer focused approach to their practice, acknowledged and supported the carer role, and made progress in identifying carer needs and accessing resources to meet these needs. Nurses experienced difficulties supporting carers who had mental health problems or previous negative experiences of services. Those who lacked community experience also found it difficult to adjust to working in a community setting. Although clinical supervision helped them to work through these difficulties, they remain largely unresolved. <i>Conclusions</i>: Findings from this study indicate that appropriate training may enable nurses to improve the support provided to carers of people diagnosed with schizophrenia. This study represents an important stage in determining the nature of support offered to carers by nurses. While developed to help nurses to meet clinical standards set for schizophrenia in the UK, findings may have clinical significance for nurses in other countries

Error Monitoring: A Learning Strategy for Improving Academic Performance of LD Adolescents

This research was published by the KU Center for Research on Learning, formerly known as the University of Kansas Institute for Research in Learning Disabilities.Error monitoring, a learning strategy for detecting and correcting errors in written products, was taught to nine learning disabled adolescents. Students could detect and correct more errors after they received training than they had detected prior to training. Error rate in self-generated products was especially low (close to zero) after training

Visual Imagery and Self-Questioning: Strategies to Improve Comprehension of Written

This research was published by the KU Center for Research on Learning, formerly known as the University of Kansas Institute for Research in Learning Disabilities.Two learning strategies, visual imagery and-self-questioning, designed to increase reading comprehension were taught to six learning disabled students using a multiple-baseline across strategies design. Results of the study indicate that LD students can learn the two strategies and can apply them in both reading-ability level and grade-level materials. The students' use of the strategies resulted in greater comprehension scores from the pretest in baseline to the posttest after training. Instructional time for each strategy ranged from five to seven hours

The Whole Genome Sequence of Sphingobium chlorophenolicum L-1: Insights into the Evolution of the Pentachlorophenol Degradation Pathway

Sphingobium chlorophenolicum Strain L-1 can mineralize the toxic pesticide pentachlorophenol (PCP). We have sequenced the genome of S. chlorophenolicum Strain L-1. The genome consists of a primary chromosome that encodes most of the genes for core processes, a secondary chromosome that encodes primarily genes that appear to be involved in environmental adaptation, and a small plasmid. The genes responsible for degradation of PCP are found on chromosome 2. We have compared the genomes of S. chlorophenolicum Strain L-1 and Sphingobium japonicum, a closely related Sphingomonad that degrades lindane. Our analysis suggests that the genes encoding the first three enzymes in the PCP degradation pathway were acquired via two different horizontal gene transfer events, and the genes encoding the final two enzymes in the pathway were acquired from the most recent common ancestor of these two bacteria

States and transitions in black-hole binaries

With the availability of the large database of black-hole transients from the Rossi X-Ray Timing Explorer, the observed phenomenology has become very complex. The original classification of the properties of these systems in a series of static states sorted by mass accretion rate proved not to be able to encompass the new picture. I outline here a summary of the current situation and show that a coherent picture emerges when simple properties such as X-ray spectral hardness and fractional variability are considered. In particular, fast transition in the properties of the fast time variability appear to be crucial to describe the evolution of black-hole transients. Based on this picture, I present a state-classification which takes into account the observed transitions. I show that, in addition to transients systems, other black-hole binaries and Active Galactic Nuclei can be interpreted within this framework. The association between these states and the physics of the accretion flow around black holes will be possible only through modeling of the full time evolution of galactic transient systems.Comment: 30 pages, 11 figures, To appear in Belloni, T.
