Why do people participate in genocide? The Complexity of Evil responds to this fundamental question by drawing on political science, sociology, criminology, anthropology, social psychology, and ...history to develop a model which can explain perpetration across various different cases. Focusing in particular on the Holocaust, the 1994 genocide against the Tutsi in Rwanda, and the Khmer Rouge genocide in Cambodia, The Complexity of Evil model draws on, systematically sorts, and causally orders a wealth of scholarly literature and supplements it with original field research data from interviews with former members of the Khmer Rouge. The model is systematic and abstract, as well as empirically grounded, providing a tool for understanding the micro-foundations of various cases of genocide. Ultimately this model highlights that the motivations for perpetrating genocide are both complex in their diversity and banal in their ordinariness and mundanity.
•Rwanda’s elite have staked their claim in good governance and inclusive development.•While primary school access has surged, repetition and dropout remain high.•Incentives tended to focus on outputs ...(building classrooms) rather than outcomes.•Policy-decisions occurred outside the sector’s strategic planning processes.•Little evidence of an effective, sustained strategy to improve education quality.
When it comes to the state’s ability to deliver services to the poor, politics matter. This paper applies a political settlements framework to examine primary education quality in Rwanda. Formal education features prominently into the post-genocide government’s social and economic development project. Rwanda’s political elite have staked their claim in the development of the country, one which is relatively free from rent-seeking. But education quality remains surprisingly low. Enrollment has surged, but primary school dropout and repetition are high. Most children have not acquired age-appropriate literacy or numeracy skills. We sought to investigate why the education sector hasn’t done better in terms of improving quality than we might have expected. This paper draws from interviews and literature review to investigate how policy development and implementation shape the provision of quality education. Our study finds that education priorities were as much political as they were developmental. A lack of real opposition or pushback enabled the government to introduce profoundly transformative educational policies, such as switching the language of instruction from French to English. Often these decisions occurred outside the sector’s strategic planning processes. Performance-based incentives tended to focus on aspects of quality that are measurable, such as the construction of classrooms, rather than improving the capacity of the teaching workforce. We did not find evidence of an effective, sustained strategy to improve education quality. It is thus debatable to what extent Rwanda’s approach can be considered as inclusive development when quality for most children remains so low. This study makes an empirical contribution through evaluating how the education sector has been situated within Rwanda’s broader political settlement, what kinds of outcomes it has led to, and why. It also makes a theoretical contribution by understanding the nature of the relationship between the national political settlement and the education sector.
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the cause of an ongoing pandemic, with increasing deaths worldwide. To date, documentation of the histopathological features in fatal ...cases of the disease caused by SARS-CoV-2 (COVID-19) has been scarce due to sparse autopsy performance and incomplete organ sampling. We aimed to provide a clinicopathological report of severe COVID-19 cases by documenting histopathological changes and evidence of SARS-CoV-2 tissue tropism.
In this case series, patients with a positive antemortem or post-mortem SARS-CoV-2 result were considered eligible for enrolment. Post-mortem examinations were done on 14 people who died with COVID-19 at the King County Medical Examiner's Office (Seattle, WA, USA) and Snohomish County Medical Examiner's Office (Everett, WA, USA) in negative-pressure isolation suites during February and March, 2020. Clinical and laboratory data were reviewed. Tissue examination was done by light microscopy, immunohistochemistry, electron microscopy, and quantitative RT-PCR.
The median age of our cohort was 73·5 years (range 42–84; IQR 67·5–77·25). All patients had clinically significant comorbidities, the most common being hypertension, chronic kidney disease, obstructive sleep apnoea, and metabolic disease including diabetes and obesity. The major pulmonary finding was diffuse alveolar damage in the acute or organising phases, with five patients showing focal pulmonary microthrombi. Coronavirus-like particles were detected in the respiratory system, kidney, and gastrointestinal tract. Lymphocytic myocarditis was observed in one patient with viral RNA detected in the tissue.
The primary pathology observed in our cohort was diffuse alveolar damage, with virus located in the pneumocytes and tracheal epithelium. Microthrombi, where observed, were scarce and endotheliitis was not identified. Although other non-pulmonary organs showed susceptibility to infection, their contribution to the pathogenesis of SARS-CoV-2 infection requires further examination.

The rapid Arctic summer sea ice reduction in the last decade has lead to debates in the maritime industries on the possibility of an increase in cargo transportation in the region. Average sailing ...times on the North Sea Route along the Siberian Coast have fallen from 20 days in the 1990s to 11 days in 2012–2013, attributed to easing sea ice conditions along the Siberian coast. However, the economic risk of exploiting the Arctic shipping routes is substantial. Here a detailed high-resolution projection of ocean and sea ice to the end of the 21st century forced with the RCP8.5 IPCC emission scenario is used to examine navigability of the Arctic sea routes. In summer, opening of large areas of the Arctic Ocean previously covered by pack ice to the wind and surface waves leads to Arctic pack ice cover evolving into the Marginal Ice Zone. The emerging state of the Arctic Ocean features more fragmented thinner sea ice, stronger winds, ocean currents and waves. By the mid 21st century, summer season sailing times along the route via the North Pole are estimated to be 13–17 days, which could make this route as fast as the North Sea Route.
•A high-resolution projection for the Arctic Ocean in the 21st century is examined.•Future navigability of the Arctic sea routes and sailing times are assessed.•Increased wind and waves transform pack ice into fragmented Marginal Ice Zone.•Arctic transit shipping saves time and fuel but may add to Arctic warming.•Forecasting requirements for the new emerging state of the Arctic are discussed.
The role of formal education in the reproduction of inequalities is well documented. Less clear is how this lens can be applied to a study of post-conflict state-building. The present study pairs ...policy analysis with student-centred ethnographic fieldwork to examine education policy in Rwanda. Since the end of the genocide, the government has staked its claim to legitimacy in delivering inclusive development. Its basic education policy is an entitlement programme with broad public support and designed to allow all children to attend primary and secondary school. Students found themselves caught up in a web of contradictions with important symbolic and material dimensions. They went to schools designed to improve access for the poor. But they were also poor schools, lacking in quality and associated with failure. The country's switch from French to English was bound up in alliances of domestic power that further undermined effective teaching and learning. The basic education policy intended to highlight the government's commitment to deliver development to all. But in absence of a sustained and effective strategy to improve quality, young people felt excluded from meaningful engagement in the education system. Whether the basic education policy constitutes inclusive development is therefore debatable.
A variational principle is proposed to derive the governing equations for the problem of ocean wave interactions with a floating ice shelf, where the ice shelf is modelled by the full linear ...equations of elasticity and has an Archimedean draught. The variational principle is used to form a thin-plate approximation for the ice shelf, which includes water–ice coupling at the shelf front and extensional waves in the shelf, in contrast to the benchmark thin-plate approximation for ocean wave interactions with an ice shelf. The thin-plate approximation is combined with a single-mode approximation in the water, where the vertical motion is constrained to the eigenfunction that supports propagating waves. The new terms in the approximation are shown to have a major impact on predictions of ice shelf strains for wave periods in the swell regime.
Summary
Heterotrophic marine bacteria play key roles in remineralizing organic matter generated from primary production. However, far more is known about which groups are dominant than about the ...cellular processes they perform in order to become dominant. In the Southern Ocean, eukaryotic phytoplankton are the dominant primary producers. In this study we used metagenomics and metaproteomics to determine how the dominant bacterial and archaeal plankton processed bloom material. We examined the microbial community composition in 14 metagenomes and found that the relative abundance of Flavobacteria (dominated by Polaribacter) was positively correlated with chlorophyll a fluorescence, and the relative abundance of SAR11 was inversely correlated with both fluorescence and Flavobacteria abundance. By performing metaproteomics on the sample with the highest relative abundance of Flavobacteria (Newcomb Bay, East Antarctica) we defined how Flavobacteria attach to and degrade diverse complex organic material, how they make labile compounds available to Alphaproteobacteria (especially SAR11) and Gammaproteobacteria, and how these heterotrophic Proteobacteria target and utilize these nutrients. The presence of methylotrophic proteins for archaea and bacteria also indicated the importance of metabolic specialists. Overall, the study provides functional data for the microbial mechanisms of nutrient cycling at the surface of the coastal Southern Ocean.
Summary
Uncultivated microbial clades (‘microbial dark matter’) are inferred to play important but uncharacterized roles in nutrient cycling. Using Antarctic lake (Ace Lake, Vestfold Hills) ...metagenomes, 12 metagenome‐assembled genomes (MAGs; 88%–100% complete) were generated for four ‘dark matter’ phyla: six MAGs from Candidatus Auribacterota (=Aureabacteria, SURF‐CP‐2), inferred to be hydrogen‐ and sulfide‐producing fermentative heterotrophs, with individual MAGs encoding bacterial microcompartments (BMCs), gas vesicles, and type IV pili; one MAG (100% complete) from Candidatus Hinthialibacterota (=OLB16), inferred to be a facultative anaerobe capable of dissimilatory nitrate reduction to ammonia, specialized for mineralization of complex organic matter (e.g. sulfated polysaccharides), and encoding BMCs, flagella, and Tad pili; three MAGs from Candidatus Electryoneota (=AABM5‐125‐24), previously reported to include facultative anaerobes capable of dissimilatory sulfate reduction, and here inferred to perform sulfite oxidation, reverse tricarboxylic acid cycle for autotrophy, and possess numerous proteolytic enzymes; two MAGs from Candidatus Lernaellota (=FEN‐1099), inferred to be capable of formate oxidation, amino acid fermentation, and possess numerous enzymes for protein and polysaccharide degradation. The presence of 16S rRNA gene sequences in public metagenome datasets (88%–100% identity) suggests these ‘dark matter’ phyla contribute to sulfur cycling, degradation of complex organic matter, ammonification and/or chemolithoautotrophic CO2 fixation in diverse global environments.
In hypersaline environments, Nanohaloarchaeota (Diapherotrites, Parvarchaeota, Aenigmarchaeota, Nanoarchaeota, Nanohaloarchaeota DPANN superphylum) are thought to be free-living microorganisms. We ...report cultivation of 2 strains of Antarctic Nanohaloarchaeota and show that they require the haloarchaeon Halorubrum lacusprofundi for growth. By performing growth using enrichments and fluorescence-activated cell sorting, we demonstrated successful cultivation of Candidatus Nanohaloarchaeum antarcticus, purification of Ca. Nha. antarcticus away from other species, and growth and verification of Ca. Nha. antarcticus with Hrr. lacusprofundi; these findings are analogous to those required for fulfilling Koch’s postulates. We use fluorescent in situ hybridization and transmission electron microscopy to assess cell structures and interactions; metagenomics to characterize enrichment taxa, generate metagenome assembled genomes, and interrogate Antarctic communities; and proteomics to assess metabolic pathways and speculate about the roles of certain proteins. Metagenome analysis indicates the presence of a single species, which is endemic to Antarctic hypersaline systems that support the growth of haloarchaea. The presence of unusually large proteins predicted to function in attachment and invasion of hosts plus the absence of key biosynthetic pathways (e.g., lipids) in metagenome assembled genomes of globally distributed Nanohaloarchaeota indicate that all members of the lineage have evolved as symbionts. Our work expands the range of archaeal symbiotic lifestyles and provides a genetically tractable model system for advancing understanding of the factors controlling microbial symbiotic relationships.
In some schools of thought of radicalisation research there is a tacit assumption that individuals become gradually radicalised in their ideas, attitudes, political preferences and worldview, and ...then motivated by this subsequently radicalise their actions to commit an act of terrorism. This article supports those who question this linear model and I argue that these two processes, which are here labelled as ideological and behavioural radicalisation, must be differentiated. Drawing on ideas from radicalisation in genocide studies, this article contributes to the social movement theory approaches to terrorism. As such, the article differentiates between ideological and behavioural radicalisation processes and argues that these two types of radicalisation can be sequenced with either first. This article posits that it is possible for individuals to engage in radical actions without having extreme preferences, just as it is equally possible for other individuals to have radical ideologies without acting on them, supporting more social movement theory approaches to radicalisation. The article provides a plausibility probe for this sequencing, demonstrating its empirical utility for participation in genocidal violence.
