Infrared spectroscopy of volcanic gases at Masaya, Nicaragua

Volcanic gases carry valuable information about processes occurring at active volcanoes, and so their accurate measurement and analysis are highly desirable. Masaya is a low-lying persistently active basaltic volcano, which is renowned for strong passive gas emission unaccompanied by lava extrusion, although it has also undergone plinian eruptions in the past. Its consistent behaviour sustains a reliable tropospheric plume, making it an ideal location at which to study volcanic degassing. During February-March 1998 and March 1999, Masaya's gas plume composition was investigated using the new ground-based remote sensing technique of open-path Fourier transform infrared spectroscopy. This technique meets criteria for safe and accurate quantitative characterisation of volcanic gases and on a temporal resolution previously impracticable. Flexibility of operation is the chief merit of OP-FTIR, since a range of infrared sources are available (e.g. an active lamp, the sun or hot volcanic vents). Laboratory calibration experiments using primary gas standards confirmed that the instrument and subsequent spectral analysis provide highly accurate concentration measurements for volcanic species, with errors typically around 5 %. Results showed that Masaya's plume composition was little changed between the field seasons. Average molar ratios for S02/HCl, HCl/HF, C02/S02 and H20/S02 were 1.6, 4.9, 2.2 and 72, respectively, in 1998, and 1.6, 5.1, 2.3 and 66 in 1999. These ratios, coupled with simultaneous COSPEC-derived SO2 data, indicated that emission rates, especially of HCl and HF, were high compared with other passively-degassing volcanoes. Measurements using the spectrometer with different infrared sources and at different locations downwind demonstrated that tropospheric scavenging processes had little discernible effect on plume composition. In the light of these new OP-FTIR gas data, possible physical mechanisms for the degassing behaviour at Masaya Volcano have been discussed. In order to account for all the observations, an integrated model, in which gas emission rates are primarily controlled by degassing-driven convection in the conduit, is proposed

Muss Rewind Therapy to alleviate symptoms related to some form of traumatic experience: A thematic analysis of participants' experiences and their perceived effectiveness of MRT

Sometimes referred to as a memory reconsolidation treatment, Muss Rewind Therapy (MRT) is a brief psychological intervention which has shown promise in treating symptoms related to some forms of traumatic experience. This study aimed at adding to minimal existing research by exploring the experiences of UK participants who have chosen to self‐refer for MRT for help with symptoms they attributed to some form of previous traumatic experience. Ten participants were interviewed online, and qualitative data were collected using video recordings and transcription. A semistructured framework was employed to explore participants' individual experiences of MRT. All participants rated MRT as helping alleviate the symptoms they related to a previous traumatic experience. Several key themes emerged regarding the participants' experiences of the treatment, including the overall role of the therapist; participants being at the end of their tether before seeking help; experiencing negative emotions during the intervention; repetition of the MRT process in the therapy room; and experiencing some positive outcomes. However, it was unclear whether positive impacts reported after MRT were due specifically to MRT or nonspecific therapy factors because of variations in the way the MRT protocol was delivered and inclusion of other techniques in or before the MRT sessions. Whilst more rigorous research is needed, including research which follows a strict protocol when MRT is provided, to compare MRT versus control group, this novel addition to the existing research, which looks at clients' perspectives on their experiences and their perceived effectiveness of MRT, can add to and inform further research development

Paramedic disaster health management competencies: a scoping review

Study/Objective: This scoping review aims to identify, categorise and explore the existing range of paramedic disaster health management competencies that have been developed internationally. The objective of the study is to assist EMS agencies to develop core competencies specific to their own environments in order to standardise teaching in the area of paramedic disaster health management response. Background: Paramedics play an essential role in all phases of disaster health management. Previous research has identified potential gaps in content and challenges to the sustainability of knowledge acquired through occasional disaster response training by paramedics. For paramedics to respond competently, they must be equipped with the necessary skills to provide comprehensive care to the populations affected by disasters. Despite this the literature shows that education and training for disaster response is variable and that an evidence based study specifically designed to outline sets of core competencies for Australian paramedics has never been undertaken. Methods: A systematic scoping review will be conducted using the Joanna Briggs Institute (JBI) methodology. The review will use information from four databases: PubMed, MEDLINE, ScienceDirect, and Scopus. Keywords and inclusion and exclusion criteria will be identified as strategies to use in this review. Results: Results will be extracted, mapped, and categorised from appropriate studies. The identified core competencies will be sorted into common domains such as communication, operations, planning, logistics, incident command systems and ethics. A descriptive analysis of the results will then be undertaken. Conclusion: Further research is needed to develop core competencies specific to Australian paramedics in order to standardise teaching in the area of disaster health management response. This study will assist agencies from all jurisdictions in evaluating or creating disaster curricula that adequately prepares and maintains paramedics for an effective all hazards disaster response

Evaluating Climate Change Adaptation from a Development Perspective

The evaluation of climate change adaptation interventions raises considerable challenges. The report, commissioned by the Global Environmental Facility (GEF), assesses the current state of evaluation of climate change adaptation interventions, identifies the main gaps in their evaluation and the current indicators being used to evaluate projects and programmes. It also assesses how to evaluate development interventions from a climate change adaptation perspective

SCOTfluors: Small, Conjugatable, Orthogonal and Tunable Fluorophores for in vivo Imaging of Cell Metabolism

The transport and trafficking of metabolites are critical for the correct functioning of live cells. However, in situ metabolic imaging studies are hampered by the lack of fluorescent chemical structures that allow direct monitoring of small metabolites under physiological conditions with high spatial and temporal resolution. Herein, we describe SCOTfluors as novel small-sized multi-colored fluorophores for real-time tracking of essential metabolites in live cells and in vivo and for the acquisition of metabolic profiles from human cancer cells of variable origin. © 2019 The Authors.

Paramedic disaster health management competencies: a scoping review

Introduction: Paramedics are tasked with providing 24/7 prehospital emergency care to the community. As part of this role, they are also responsible for providing emergency care in the event of a major incident or disaster. They play a major role in the response stage of such events, both domestic and international. Despite this, specific standardized training in disaster management appears to be variable and inconsistent throughout the profession. A suggested method of building disaster response capacities is through competency-based education (CBE). Core competencies can provide the fundamental basis of collective learning and help ensure consistent application and translation of knowledge into practice. These competencies are often organized into domains, or categories of learning outcomes, as defined by Blooms taxonomy of learning domains. It is these domains of competency, as they relate to paramedic disaster response, that are the subject of this review. Methods: The methodology for this paper to identify existing paramedic disaster response competency domains was adapted from the guidance for the development of systematic scoping reviews, using a methodology developed by members of the Joanna Briggs Institute (JBI; Adelaide, South Australia) and members of five Joanna Briggs Collaborating Centres. Results: The literature search identified six articles for review that reported on paramedic disaster response competency domains. The results were divided into two groups: (1) General Core Competency Domains, which are suitable for all paramedics (both Advanced Life Support [ALS] and Basic Life Support [BLS]) who respond to any disaster or major incident; and (2) Specialist Core Competencies, which are deemed necessary competencies to enable a response to certain types of disaster. Further review then showed that three separate and discrete types of competency domains exits in the literature: (1) Core Competencies, (2) Technical/Clinical Competencies, and (3) Specialist Technical/Clinal Competencies. Conclusions: The most common domains of core competencies for paramedic first responders to manage major incidents and disasters described in the literature were identified. If it’s accepted that training paramedics in disaster response is an essential part of preparedness within the disaster management cycle, then by including these competency domains into the curriculum development of localized disaster training programs, it will better prepare the paramedic workforce’s competence and ability to effectively respond to disasters and major incidents
