Mandatory reporting of sexual and gender-based violence in humanitarian settings: a qualitative analysis of international guidelines for humanitarian practitioners and scoping review of existing evidence

Background: Mandatory reporting requirements create an ethical and legal dilemma for humanitarian practitioners working with survivors of sexual and gender-based violence (SGBV), as they are required to report known instances of SGBV to law enforcement, sometimes without the consent of victims or as a precondition to administering care. However, there remains a paucity of research on this topic in the context of humanitarian settings to guide practitioners on how to navigate mandatory reporting requirements from a survivor-centered approach. This study seeks to contribute to the existing knowledge and debate on mandatory reporting for SGBV in humanitarian settings by reviewing the current literature and international GBV guidelines for humanitarian practitioners. Methods: We conducted an abductive thematic analysis of key international GBV guidelines for humanitarian workers to explore the practices and guidance developed around mandatory reporting. GBV guidelines were identified by a search on agencies’ websites under consultations with experts in the field of sexual and reproductive health. In parallel, we conducted a scoping review of five academic databases with no earliest inclusion date, and a final inclusion date of 31 March 2023 to identify the scope and extent of research on SGBV mandatory reporting in humanitarian settings. Findings: We identified thirty-one relevant international GBV guideline documents which provide guidance for humanitarian practitioners on implementing mandatory reporting requirements. The availability and depth of information regarding mandatory reporting varies in the international guidelines. Three themes, including “GBV guiding principles”, “consideration for the impact of mandatory reporting and the reporting obligations” and “guidance for humanitarian providers on how to implement mandatory reporting requirements” emerged from the GBV guideline content analysis. As part of the scoping review, 1474 records were reviewed, with only 5 publications meeting our eligibility criteria. The 5 selected publications contained only limited information about mandatory reporting. Conclusion: Existing guidelines would benefit from incorporating more systematic and detailed guidance on how to navigate mandatory reporting requirements while upholding survivor-centered responses. There remains little evidence on the implementation or effectiveness of mandatory reporting in humanitarian settings, and of the implementation of guidance pertaining to mandatory reporting included in international GBV guidelines. Further research is necessary to clarify its implications and support evidence-based guidance for humanitarian personnel

Accuracy of right atrial pressure estimation using a multi-parameter approach derived from inferior vena cava semi-automated edge-tracking echocardiography: a pilot study in patients with cardiovascular disorders

The echocardiographic estimation of right atrial pressure (RAP) is based on the size and inspiratory collapse of the inferior vena cava (IVC). However, this method has proven to have limits of reliability. The aim of this study is to assess feasibility and accuracy of a new semi-automated approach to estimate RAP. Standard acquired echocardiographic images were processed with a semi-automated technique. Indexes related to the collapsibility of the vessel during inspiration (Caval Index, CI) and new indexes of pulsatility, obtained considering only the stimulation due to either respiration (Respiratory Caval Index, RCI) or heartbeats (Cardiac Caval Index, CCI) were derived. Binary Tree Models (BTM) were then developed to estimate either 3 or 5 RAP classes (BTM3 and BTM5) using indexes estimated by the semi-automated technique. These BTMs were compared with two standard estimation (SE) echocardiographic methods, indicated as A and B, distinguishing among 3 and 5 RAP classes, respectively. Direct RAP measurements obtained during a right heart catheterization (RHC) were used as reference. 62 consecutive \u2018all-comers\u2019 patients that had a RHC were enrolled; 13 patients were excluded for technical reasons. Therefore 49 patients were included in this study (mean age 62.2\ua0\ub1\ua015.2\ua0years, 75.5% pulmonary hypertension, 34.7% severe left ventricular dysfunction and 51% right ventricular dysfunction). The SE methods showed poor accuracy for RAP estimation (method A: misclassification error, ME\ua0=\ua051%, R2\ua0=\ua00.22; method B: ME\ua0=\ua069%, R2\ua0=\ua00.26). Instead, the new semi-automated methods BTM3 and BTM5 have higher accuracy (ME\ua0=\ua014%, R2\ua0=\ua00.47 and ME\ua0=\ua022%, R2\ua0=\ua00.61, respectively). In conclusion, a multi-parametric approach using IVC indexes extracted by the semi-automated approach is a promising tool for a more accurate estimation of RAP

A composite approach to produce reference datasets for extratropical cyclone tracks: application to Mediterranean cyclones

Many cyclone detection and tracking methods (CDTMs) have been developed in the past to study the climatology of extratropical cyclones. However, all CDTMs have different approaches in defining and tracking cyclone centers. This naturally leads to cyclone track climatologies with inconsistent physical characteristics. More than that, it is typical for CDTMs to produce a non-negligible number of tracks of weak atmospheric features, which do not correspond to large-scale or mesoscale vortices and can differ significantly between CDTMs. Lack of consensus in CDTM outputs and the inclusion of significant numbers of uncertain tracks therein have long prohibited the production of a commonly accepted reference dataset of extratropical cyclone tracks. Such a dataset could allow comparable results on the analysis of storm track climatologies and could also contribute to the evaluation and improvement of CDTMs. To cover this gap, we present a new methodological approach that combines overlapping tracks from different CDTMs and produces composite tracks that concentrate the agreement of more than one CDTM. In this study we apply this methodology to the outputs of 10 well-established CDTMs which were originally applied to ERA5 reanalysis in the 42-year period of 1979-2020. We tested the sensitivity of our results to the spatiotemporal criteria that identify overlapping cyclone tracks, and for benchmarking reasons, we produced five reference datasets of subjectively tracked cyclones. Results show that climatological numbers of composite tracks are substantially lower than the ones of individual CDTMs, while benchmarking scores remain high (i.e., counting the number of subjectively tracked cyclones captured by the composite tracks). Our results show that composite tracks tend to describe more intense and longer-lasting cyclones with more distinguished early, mature and decay stages than the cyclone tracks produced by individual CDTMs. Ranking the composite tracks according to their confidence level (defined by the number of contributing CDTMs), it is shown that the higher the confidence level, the more intense and long-lasting cyclones are produced. Given the advantage of our methodology in producing cyclone tracks with physically meaningful and distinctive life stages, we propose composite tracks as reference datasets for climatological research in the Mediterranean. The Supplement provides the composite Mediterranean tracks for all confidence levels, and in the conclusion we discuss their adequate use for scientific research and applications

Recent Developments in Understanding Two-dimensional Turbulence and the Nastrom-Gage Spectrum

Two-dimensional turbulence appears to be a more formidable problem than three-dimensional turbulence despite the numerical advantage of working with one less dimension. In the present paper we review recent numerical investigations of the phenomenology of two-dimensional turbulence as well as recent theoretical breakthroughs by various leading researchers. We also review efforts to reconcile the observed energy spectrum of the atmosphere (the spectrum) with the predictions of two-dimensional turbulence and quasi-geostrophic turbulence.Comment: Invited review; accepted by J.
