Attribution: how is it relevant for loss and damage policy and practice?
Attribution has become a recurring issue in discussions about Loss and Damage (L&D). In this highly-politicised context, attribution is often associated with responsibility and blame; and linked to debates about liability and compensation. The aim of attribution science, however, is not to establish responsibility, but to further scientific understanding of causal links between elements of the Earth System and society. This research into causality could inform the management of climate-related risks through improved understanding of drivers of relevant hazards, or, more widely, vulnerability and exposure; with potential benefits regardless of political positions on L&D. Experience shows that it is nevertheless difficult to have open discussions about the science in the policy sphere. This is not only a missed opportunity, but also problematic in that it could inhibit understanding of scientific results and uncertainties, potentially leading to policy planning which does not have sufficient scientific evidence to support it. In this chapter, we first explore this dilemma for science-policy dialogue, summarising several years of research into stakeholder perspectives of attribution in the context of L&D. We then aim to provide clarity about the scientific research available, through an overview of research which might contribute evidence about the causal connections between anthropogenic climate change and losses and damages, including climate science, but also other fields which examine other drivers of hazard, exposure, and vulnerability. Finally, we explore potential applications of attribution research, suggesting that an integrated and nuanced approach has potential to inform planning to avert, minimise and address losses and damages. The key messages are
In the political context of climate negotiations, questions about whether losses and damages can be attributed to anthropogenic climate change are often linked to issues of responsibility, blame, and liability.
Attribution science does not aim to establish responsibility or blame, but rather to investigate drivers of change.
Attribution science is advancing rapidly, and has potential to increase understanding of how climate variability and change is influencing slow onset and extreme weather events, and how this interacts with other drivers of risk, including socio-economic drivers, to influence losses and damages.
Over time, some uncertainties in the science will be reduced, as the anthropogenic climate change signal becomes stronger, and understanding of climate variability and change develops.
However, some uncertainties will not be eliminated. Uncertainty is common in science, and does not prevent useful applications in policy, but might determine which applications are appropriate. It is important to highlight that in attribution studies, the strength of evidence varies substantially between different kinds of slow onset and extreme weather events, and between regions. Policy-makers should not expect the later emergence of conclusive evidence about the influence of climate variability and change on specific incidences of losses and damages; and, in particular, should not expect the strength of evidence to be equal between events, and between countries.
Rather than waiting for further confidence in attribution studies, there is potential to start working now to integrate science into policy and practice, to help understand and tackle drivers of losses and damages, informing prevention, recovery, rehabilitation, and transformation
Review article: Use of ultrasound in the developing world
As portability and durability improve, bedside, clinician-performed ultrasound is seeing increasing use in rural, underdeveloped parts of the world. Physicians, nurses and medical officers have demonstrated the ability to perform and interpret a large variety of ultrasound exams, and a growing body of literature supports the use of point-of-care ultrasound in developing nations. We review, by region, the existing literature in support of ultrasound use in the developing world and training guidelines currently in use, and highlight indications for emergency ultrasound in the developing world. We suggest future directions for bedside ultrasound use and research to improve diagnostic capacity and patient care in the most remote areas of the globe
Uncovering the multifaceted roles played by neutrophils in allogeneic hematopoietic stem cell transplantation
Allogeneic hematopoietic stem cell transplantation (alloHSCT) is a life-saving procedure used for the treatment of selected hematological malignancies, inborn errors of metabolism, and bone marrow failures. The role of neutrophils in alloHSCT has been traditionally evaluated only in the context of their ability to act as a first line of defense against infection. However, recent evidence has highlighted neutrophils as key effectors of innate and adaptive immune responses through a wide array of newly discovered functions. Accordingly, neutrophils are emerging as highly versatile cells that are able to acquire different, often opposite, functional capacities depending on the microenvironment and their differentiation status. Herein, we review the current knowledge on the multiple functions that neutrophils exhibit through the different stages of alloHSCT, from the hematopoietic stem cell (HSC) mobilization in the donor to the immunological reconstitution that occurs in the recipient following HSC infusion. We also discuss the influence exerted on neutrophils by the immunosuppressive drugs delivered in the course of alloHSCT as part of graft-versus-host disease (GVHD) prophylaxis. Finally, the potential involvement of neutrophils in alloHSCT-related complications, such as transplant-associated thrombotic microangiopathy (TA-TMA), acute and chronic GVHD, and cytomegalovirus (CMV) reactivation, is also discussed. Based on the data reviewed herein, the role played by neutrophils in alloHSCT is far greater than a simple antimicrobial role. However, much remains to be investigated in terms of the potential functions that neutrophils might exert during a highly complex procedure such as alloHSCT
O potencial pedagógico da Hora do Conto para o desenvolvimento da Comunicação Oral
O presente relatório é produto de um projeto de investigação que pretendeu caracterizar a adequação e dinamização da hora do conto com a finalidade de promover o desenvolvimento da comunicação oral, implementada numa sala de 3/4 anos e a adequação didática de um processo de intervenção educativa de estratégias para a promoção do desenvolvimento da Oralidade (incidindo na dinamização da hora conto) implementado numa turma de 3.º ano do 1.º Ciclo do Ensino Básico. Tendo consciência da desvalorização que é atribuída à temática em análise, acreditamos que os profissionais de educação se tornam responsáveis pelo desenvolvimento e aperfeiçoamento das capacidades de comunicação das crianças/alunos. Neste sentido, consideramos que foi extremamente importante investir neste domínio e nas competências a ele associado, nas vertentes de compreensão e expressão orais.
Para atingir os objetivos delineamos, planificamos, construímos, aplicamos e avaliamos em sala de aula, um conjunto de intervenções educativas adotando como estratégia principal a dinamização da hora do conto. Assim sendo, podemos verificar através dos resultados obtidos, que efetivamente, a hora do conto e a utilização de diferentes estratégias para a dinamização da mesma, contribuíram positivamente para o desenvolvimento das competências orais dos intervenientes, potenciando melhorias, a vários níveis, nomeadamente na vertente de compressão e de expressão oral dos dois grupos de aplicação.This report is the product of a research project that aimed to characterize the adequacy and dynamization of the story time with the purpose of promoting the development of oral communication, implemented in a 3/4 year classroom and the didactic adequacy of a process of educational intervention strategies to promote the development of Orality (focusing on the dynamization of the story time) implemented in a 3rd year class of the 1st Cycle of Basic Education. Being aware of the devaluation that is attributed to the theme under analysis, we believe that education professionals become responsible for the development and improvement of communication skills of children/students. In this sense, we believe that it was extremely important to invest in this field and in the skills associated with it, in the areas of understanding and oral expression.
In order to achieve the objectives, we delineate, plan, build, apply and evaluate in the classroom, a set of educational interventions adopting as the main strategy the dynamization of the story time. Therefore, we can verify through the results obtained, that effectively, the story time and the use of different strategies for the dynamization of the tale, contributed positively to the development of the oral skills of the participants, enhancing improvements, at various levels, particularly in the compression and oral expression of the two groups of application.
Keywords: Oral Communication; Compression and Oral Expression; Story Time; Pre-School; 1st Cycle of Basic Education
Short-term effects of crisis response planning on optimism in a U.S. Army sample
Aim: This study examined the short-term effects of a brief crisis intervention on optimism of acutely suicidal soldiers. Methods: U.S. Soldiers (N = 97) presenting for an emergency mental health appointment in a military emergency department or behavioural health clinic were randomly assigned to treatment as usual standard crisis response plan, or enhanced crisis response plan (E-CRP). This study is used a subsample of the original clinical trial (n = 64) for those who completed self-report measures of optimism (Life Orientation Test-Revised) prior to receiving any intervention and a secondary self-report assessment one-month following the intervention. Results: Results indicate that individuals with low baseline optimism who received the E-CRP had significant increases in optimism 1 month post-intervention. Conclusion: This provides evidence that discussing a patient's reasons for living during a CRP increases optimism in those high-risk patients with the lowest baseline optimism. © 2018 John Wiley & Sons Australia, Lt
Looking at Nitrogenase: Insights from Modern Structural Approaches
Nitrogenase, the primary biological source of fixed nitrogen, has been studied by various biochemical and biophysical methods to determine the mechanism of nitrogen reduction to ammonia. Previously, structural studies have contributed to determining the arrangement and identity of the unique metallocofactors of the as-isolated nitrogenase enzyme. Due to the multi-protein, dynamic nature of catalysis in nitrogenase, structurally capturing intermediates is not trivial. Recently, we have developed methods for preparing crystallographic samples of nitrogenase from active assay mixtures. The “out-of-assay” approach has yielded structures of small molecules bound to the active site cofactor, revealing an unexpected rearrangement of the belt sulfur atoms. The activity-based methods provide a framework for accessing non-resting states of the cofactor and introduce new questions surrounding the controlled binding and release of substrates. In the following, we discuss recent structural advances in the field and the novel directions for future activity-based research
Using patient‐reported outcomes to understand the effectiveness of guideline‐concordant care for post‐traumatic stress disorder in clinical practice
RationaleIdentifying predictors of improvement amongst patients receiving routine treatment for post-traumatic stress disorder (PTSD) could provide information about factors that influence the clinical effectiveness of guideline-concordant care. This study builds on prior work by accounting for delivery of specific evidence-based treatments (EBTs) for PTSD while identifying potential predictors of clinical improvement using patient-reported outcomes measurement.MethodOur sample consisted of 2 643 US Department of Veterans Affairs (VA) outpatients who initiated treatment for PTSD between 2008 and 2013 and received at least four PTSD checklist (PCL) measurements over 12 weeks. We obtained PCL data as well as demographic, diagnostic, and health services use information from the VA corporate data warehouse. We used latent trajectory analysis to identify classes of patients based on PCL scores, then determined demographic, diagnostic, and treatment predictors of membership in each class.ResultsPatients who met our PCL-based inclusion criteria were far more likely than those who did not receive EBTs. We identified two latent trajectories of PTSD symptoms. Patients in the substantial improvement group (25.9%) had a mean decrease in PCL score of 16.24, whereas patients in the modest improvement group improved by a mean of 8.09 points. However, there were few differences between the groups, and our model to predict group membership was only slightly better than chance (area under the curve [AUC] = 0.55). Of the 64 covariates we tested, the only robust individual predictor of improvement was gender, with men having lower odds of being in the substantial improvement group compared with women (odds ratio [OR] 0.76; 95% confidence interval [CI] 0.58-0.96).ConclusionVA patients with PTSD can realize significant improvement in routine clinical practice. Although available medical records-based variables were generally insufficient to predict improvement trajectory, this study did indicate that men have lower odds of substantial improvement than women
