The Political Theology of Violence in Contemporary India

What are we to make of the fact that most violence in India rarely has any visible or clear actors? Why is most violence represented as ‘pure events’ without identifiable actors—but as ‘mobs’, as spontaneous combustion, as spontaneous rage that arises from perceived collective grievances and insults? Why in a country saturated in political rhetoric is it that acts of violence have acquired their own semiotic register, a singular form of ‘political communication’? Fire and incidents of arson are at the heart of this naturalization of violence, as events without actors. Fire is not only one of the densest cultural signifiers in India, it also is at the heart of the transgressions, the exceptions, the taboos, the sacrifices, the agency, the sense of communitas that unfold in times of heightened conflict and violent clashes with the state or other communities. Drawing on examples from Mumbai and elsewhere, the paper attempts to theorize and elaborate the nexus between fire, violence and collective sentiments

Bacterial diversity in snow on North Pole ice floes

The microbial abundance and diversity in snow on ice floes at three sites near the North Pole was assessed using quantitative PCR and 454 pyrosequencing. Abundance of 16S rRNA genes in the samples ranged between 43 and 248 gene copies per millilitre of melted snow. A total of 291,331 sequences were obtained through 454 pyrosequencing of 16S rRNA genes, resulting in 984 OTUs at 97 % identity. Two sites were dominated by Cyanobacteria (72 and 61 %, respectively), including chloroplasts. The third site differed by consisting of 95 % Proteobacteria. Principal component analysis showed that the three sites clustered together when compared to the underlying environments of sea ice and ocean water. The Shannon indices ranged from 2.226 to 3.758, and the Chao1 indices showed species richness between 293 and 353 for the three samples. The relatively low abundances and diversity found in the samples indicate a lower rate of microbial input to this snow habitat compared to snow in the proximity of terrestrial and anthropogenic sources of microorganisms. The differences in species composition and diversity between the sites show that apparently similar snow habitats contain a large variation in biodiversity, although the differences were smaller than the differences to the underlying environment. The results support the idea that a globally distributed community exists in snow and that the global snow community can in part be attributed to microbial input from the atmosphere.

High levels of iron supplementation prevents neural tube defects in the Fpn1(ffe) mouse model.

BACKGROUND: Periconception maternal nutrition and folate in particular are important factors influencing the incidence of neural tube defects (NTDs). Many but not all NTDs are prevented by folic acid supplementation and there is a pressing need for additional strategies to prevent these birth defects. Other micronutrients such as iron are potential candidates, yet a clear role for iron deficiency in contributing to NTDs is lacking. Our previous studies with the flatiron (ffe) mouse model of Ferroportin1 (Fpn1) deficiency suggest that iron is required for neural tube closure and forebrain development raising the possibility that iron supplementation could prevent NTDs. METHODS: We determined the effect of periconception iron and/or folic acid supplementation on the penetrance of NTDs in the Fpn1(ffe) mouse model. Concurrently, measurements of folate and iron were made to ensure supplementation had the intended effects. RESULTS: High levels of iron supplementation significantly reduced the incidence of NTDs in Fpn1(ffe) mutants. Fpn1 deficiency resulted in reduced folate levels in both pregnant dams and embryos. Yet folic acid supplementation did not prevent NTDs in the Fpn1(ffe) model. Similarly, forebrain truncations were rescued with iron. Surprisingly, the high levels of iron supplementation used in this study caused folate deficiency in wild-type dams and embryos. CONCLUSION: Our results demonstrate that iron supplementation can prevent NTDs and forebrain truncations in the Fpn1(ffe) model. Surprisingly, high levels of iron supplementation and iron overload can cause folate deficiency. If iron is essential for neural tube closure, it is possible that iron deficiency might contribute to NTDs.

Discovery of drug-omics associations in type 2 diabetes with generative deep-learning models.

The application of multiple omics technologies in biomedical cohorts has the potential to reveal patient-level disease characteristics and individualized response to treatment. However, the scale and heterogeneous nature of multi-modal data makes integration and inference a non-trivial task. We developed a deep-learning-based framework, multi-omics variational autoencoders (MOVE), to integrate such data and applied it to a cohort of 789 people with newly diagnosed type 2 diabetes with deep multi-omics phenotyping from the DIRECT consortium. Using in silico perturbations, we identified drug-omics associations across the multi-modal datasets for the 20 most prevalent drugs given to people with type 2 diabetes with substantially higher sensitivity than univariate statistical tests. From these, we among others, identified novel associations between metformin and the gut microbiota as well as opposite molecular responses for the two statins, simvastatin and atorvastatin. We used the associations to quantify drug-drug similarities, assess the degree of polypharmacy and conclude that drug effects are distributed across the multi-omics modalities.

Certifications of citizenship: the history, politics and materiality of identity documents in South Asian states and diasporas

Experiences in the post-partition Indian subcontinent refute the conventional expectation that the 'possession of citizenship enables the acquisition of documents certifying it' (Jayal, 2013, 71). Instead, identity papers of various types play a vital part in certifying and authenticating claims to citizenship. This is particularly important in a context where the history of state formation, continuous migration flows and the rise of right-wing majoritarian politics has created an uncertain situation for individuals deemed to be on the ‘margins’ of the state. The papers that constitute this special issue bring together a range of disciplinary perspectives in order to investigate the history, politics and materiality of identity documents, and to dismantle citizenship as an absolute and fixed notion, seeking instead to theorise the very mutable ‘hierarchies’ and ‘degrees’ of citizenship. Collectively they offer a valuable lens onto how migrants, refugees and socio-economically marginal individuals negotiate their relationship with the state, both within South Asia and in South Asian diaspora communities. This introduction examines the wider context of the complex intersections between state-issued identity documents and the nature of citizenship and draws out cross-cutting themes across the papers in this collection
