Refugees in Cities: The Politics of Knowledge

Forced migration studies is a politically charged field of study. The phenomenon of forced migration challenges its researchers to tackle complex questions about the limits of gathering knowledge in the face of political interests and human suffering. However, explicit critical reflection on the politics of knowledge inherent in individual refugee research has been very scant. This article addresses some of the relevant issues, that is, questions of perspective and positionality, truth and representation.Les études sur la migration forcée représentent un champ d’étude politiquement sensible. Le phénomène de migration forcée présente à ses chercheurs le défi de s'attaquer aux questions complexes concernant les limites du rassemblement de la connaissance face aux intérêts politiques et à la souffrance humaine. Cependant, la réflexion critique explicite sur la politique de la connaissance inhérente à la recherche sur les réfugiés individuels a été très peu abondante. Cet article traite de quelques problèmes pertinents, c'est-à-dire les questions de perspective et d’angle de vue, de vérité et de représentation

Scaling knowledge and innovations for food and nutrition security— Tackling dilemmas and blind spots

Global food systems need to become more sustainable, resilient and inclusive. To accelerate this transition, there is a need for scaling innovative strategies for improved Food and Nutrition Security (FNS), particularly for the poor and marginalised. Scaling, however, is not a straightforward or value-free process. The synthesis study examined which dilemmas influence Research for Impact projects that seek to contribute to FNS outcomes at scale, and how blind spots in scaling research and practice are tied to these dilemmas. Being aware of and tackling these blind spots at an early stage contributes to ‘responsible scaling’: not only focusing on technical and socio-economic, but also on ethical considerations about who will benefit or lose out. The findings presented in the full paper are based on insights from ten interdisciplinary research projects funded by NWO-WOTRO that were carried out in countries in East, Southern and the Horn of Africa between 2014–2020

Perspectives on “Giving Back”: A Conversation Between Researcher and Refugee

Our chapter—“Perspectives on ‘giving back’: A conversation between researcher and refugee”—offers personal reflections on the ethics of research with refugees and what it means for researchers to “give back” to refugee participants beyond “policy impact”. Written as a dialogue between an academic and a Rohingya refugee youth leader, we explore the blurry lines between academic work and advocacy when the issues of refugee protection are pressing, as well as the appropriateness of researchers giving monetary donations and volunteering for refugee causes as payback for data. In this chapter, we also examine what it means to build trust and relationships between researchers and refugees, and how too often researchers fail to develop meaningful research interactions with refugee participants who share their time, energy and personal stories of vulnerability

A water column study of methane around gas flares located at the West Spitsbergen continental margin

In the Arctic Seas, the West Spitsbergen continental margin represents a prominent methane seep area. In this area, free gas formation and gas ebullition as a consequence of hydrate dissociation due to global warming are currently under debate. Recent studies revealed shallow gas accumulation and ebullition of methane into the water column at more than 250 sites in an area of 665 km2. We conducted a detailed study of a subregion of this area, which covers an active gas ebullition area of 175 km2 characterized by 10 gas flares reaching from the seafloor at~245 m up to 50 m water depth to identify the fate of the released gas due to dissolution of methane from gas bubbles and subsequent mixing, transport and microbial oxidation. The oceanographic data indicated a salinity-controlled pycnocline situated ~20 m above the seafloor. A high resolution sampling program at the pycnocline at the active gas ebullition flare area revealed that the methane concentration gradient is strongly controlled by the pycnocline. While high methane concentrations of up to 524 nmol L−1 were measured below the pycnocline, low methane concentrations of less than 20 nmol L−1 were observed in the water column above. Variations in the δ13CCH4 values point to a 13C depleted methane source (~−60‰ VPDB) being mainly mixed with a background values of the ambient water (~−37.5‰ VPDB). A gas bubble dissolution model indicates that ~80% of the methane released from gas bubbles into the ambient water takes place below the pycnocline. This dissolved methane will be laterally transported with the current northwards and most likely microbially oxidized in between 50 and 100 days, since microbial CH4 oxidation rates of 0.78 nmol d−1 were measured. Above the pycnocline, methane concentrations decrease to local background concentration of ~10 nmol L−1. Our results suggest that the methane dissolved from gas bubbles is efficiently trapped below the pycnocline and thus limits the methane concentration in surface water and the air–sea exchange during summer stratification. During winter the lateral stratification breaks down and fractions of the bottom water enriched in methane may be vertically mixed and thus be potentially an additional source for atmospheric methane

Prospective individual patient data meta-analysis of two randomized trials on convalescent plasma for COVID-19 outpatients

Data on convalescent plasma (CP) treatment in COVID-19 outpatients are scarce. We aimed to assess whether CP administered during the first week of symptoms reduced the disease progression or risk of hospitalization of outpatients. Two multicenter, double-blind randomized trials (NCT04621123, NCT04589949) were merged with data pooling starting when = 50 years and symptomatic for <= 7days were included. The intervention consisted of 200-300mL of CP with a predefined minimum level of antibodies. Primary endpoints were a 5-point disease severity scale and a composite of hospitalization or death by 28 days. Amongst the 797 patients included, 390 received CP and 392 placebo; they had a median age of 58 years, 1 comorbidity, 5 days symptoms and 93% had negative IgG antibody-test. Seventy-four patients were hospitalized, 6 required mechanical ventilation and 3 died. The odds ratio (OR) of CP for improved disease severity scale was 0.936 (credible interval (CI) 0.667-1.311); OR for hospitalization or death was 0.919 (CI 0.592-1.416). CP effect on hospital admission or death was largest in patients with <= 5 days of symptoms (OR 0.658, 95%CI 0.394-1.085). CP did not decrease the time to full symptom resolution

The ARID1B spectrum in 143 patients: from nonsyndromic intellectual disability to Coffin–Siris syndrome

Purpose: Pathogenic variants in ARID1B are one of the most frequent causes of intellectual disability (ID) as determined by large-scale exome sequencing studies. Most studies published thus far describe clinically diagnosed Coffin–Siris patients (ARID1B-CSS) and it is unclear whether these data are representative for patients identified through sequencing of unbiased ID cohorts (ARID1B-ID). We therefore sought to determine genotypic and phenotypic differences between ARID1B-ID and ARID1B-CSS. In parallel, we investigated the effect of different methods of phenotype reporting. Methods: Clinicians entered clinical data in an extensive web-based survey. Results: 79 ARID1B-CSS and 64 ARID1B-ID patients were included. CSS-associated dysmorphic features, such as thick eyebrows, long eyelashes, thick alae nasi, long and/or broad philtrum, small nails and small or absent fifth distal phalanx and hypertrichosis, were observed significantly more often (p < 0.001) in ARID1B-CSS patients. No other significant differences were identified. Conclusion: There are only minor differences between ARID1B-ID and ARID1B-CSS patients. ARID1B-related disorders seem to consist of a spectrum, and patients should be managed similarly. We demonstrated that data collection methods without an explicit option to report the absence of a feature (such as most Human Phenotype Ontology-based methods) tended to underestimate gene-related features
