Review Essay: Biopolitics 2.0 – Reclaiming the Power of Life in the Anthropocene

Biopolitics was once the preserve of critical Foucauldian-influenced theorists. This is no longer the case. The rise of new materialisms, networked and object-oriented ontologies and demands for the ‘renaturalization of politics’ (Grosz, 2011; Sharp, 2011) have turned the political into the biopolitical in much of radical contemporary political theory. Here, the biopolitical is often in tension with the Foucauldian discourses of the last few decades, affirming alternative possibilities rather than merely critiquing regimes of power (Malabou, 2008; Kirby, 2011; Taussig, 2018). One factor in this shift has been the impact of anthropogenic climate change and global warming on the contemporary political imagination, increasingly refracted through conceptualizations of the Anthropocene (Tsing, 2015; Cohen et al, 2016; Chandler, 2018). A second factor has been that the life sciences no longer appear to support understandings of deterministic differences but rather to cast evolution in sympoietic and entangled ways, making biology appear as no longer essentialising but as increasingly importable into politics, in ways which disrupt modernist or liberal conceptions of the culture/nature divide (Haraway, 2016). Two important but very different engagements, which reflect these affirmative readings of biopolitics, are reviewed here, from the fields of postcolonial literature and gender and race in international politics

Aerial wetting contact angle measurement using confocal microscopy

A method is presented in which the wetting contact angle of a sessile drop is acquired aerially using confocal techniques to measure the radius and the height of a droplet deposited on a planar surface. The repeatability of this method is typically less than 0.25°, and often less than 0.1°, for droplet diameters less than 1 mm. To evaluate accuracy of this method, an instrument uncertainty budget is developed, which predicts a combined uncertainty of 0.91° for a 1 mm diameter water droplet with a contact angle of 110°. For droplets having diameters less than 1 mm and contact angles between 15° and 160°, these droplets approach spherical shape and their contact angles can be computed analytically with less than 1% error. For larger droplets, gravitational deformation needs to be considered

Plastic possibilities: Contrasting the uses of plastic ‘waste’ in India

This is the final version. Available on open access from Wiley via the DOI in this recordThis article draws on examples of inventive plastic reuse from India and personal anecdotes of elders as an anthropological reflection on possible plastic futures. It sketches the large-scale governmental reforms in the domain of municipal solid waste management, or MSWM (which, by legal definition in India, includes plastic waste). In this regard, it draws out some of the problematic socio-political and environmental implications of Prime Minister Narendra Modi's ‘Clean India’ campaign, whose technocratic policy orientations towards standardized centralized MSWM echo his cultural nationalist agenda. These reforms contrast with home-based re-engineering methods and the redeploying of plastic discards (thereby making them notuner moton (‘like new again’), and their localized circulation through relatively local but uneven reputational and economic networks. Clean India sequesters and processes vast quantities of plastics through the wide-ranging adoption of a waste-to-energy techno-fix (in which plastics are incinerated). In contrast, the authors illustrate routine practices and relations whereby people reuse, repurpose and recycle plastics. While Clean India can detract from and disrupt these mundane practices and everyday relations, these are suggestive of alternative plastic futures – both socio-material and environmental

A single intranasal dose of chimpanzee adenovirus-vectored vaccine protects against SARS-CoV-2 infection in rhesus macaques

The deployment of a vaccine that limits transmission and disease likely will be required to end the coronavirus disease 2019 (COVID-19) pandemic. We recently described the protective activity of an intranasally administered chimpanzee adenovirus-vectored vaccine encoding a pre-fusion stabilized spike (S) protein (ChAd-SARS-CoV-2-S [chimpanzee adenovirus-severe acute respiratory syndrome-coronavirus-2-S]) in the upper and lower respiratory tracts of mice expressing the human angiotensin-converting enzyme 2 (ACE2) receptor. Here, we show the immunogenicity and protective efficacy of this vaccine in non-human primates. Rhesus macaques were immunized with ChAd-Control or ChAd-SARS-CoV-2-S and challenged 1 month later by combined intranasal and intrabronchial routes with SARS-CoV-2. A single intranasal dose of ChAd-SARS-CoV-2-S induces neutralizing antibodies and T cell responses and limits or prevents infection in the upper and lower respiratory tracts after SARS-CoV-2 challenge. As ChAd-SARS-CoV-2-S confers protection in non-human primates, it is a promising candidate for limiting SARS-CoV-2 infection and transmission in humans

On finite-horizon control of genetic regulatory networks with multiple hard-constraints

<p>Abstract</p> <p>Background</p> <p>Probabilistic Boolean Networks (PBNs) provide a convenient tool for studying genetic regulatory networks. There are three major approaches to develop intervention strategies: (1) resetting the state of the PBN to a desirable initial state and letting the network evolve from there, (2) changing the steady-state behavior of the genetic network by minimally altering the rule-based structure and (3) manipulating external control variables which alter the transition probabilities of the network and therefore desirably affects the dynamic evolution. Many literatures study various types of external control problems, with a common drawback of ignoring the number of times that external control(s) can be applied.</p> <p>Results</p> <p>This paper studies the intervention problem by manipulating multiple external controls in a finite time interval in a PBN. The maximum numbers of times that each control method can be applied are given. We treat the problem as an optimization problem with multi-constraints. Here we introduce an algorithm, the "Reserving Place Algorithm'', to find all optimal intervention strategies. Given a fixed number of times that a certain control method is applied, the algorithm can provide all the sub-optimal control policies. Theoretical analysis for the upper bound of the computational cost is also given. We also develop a heuristic algorithm based on Genetic Algorithm, to find the possible optimal intervention strategy for networks of large size. </p> <p>Conclusions</p> <p>Studying the finite-horizon control problem with multiple hard-constraints is meaningful. The problem proposed is NP-hard. The Reserving Place Algorithm can provide more than one optimal intervention strategies if there are. Moreover, the algorithm can find all the sub-optimal control strategies corresponding to the number of times that certain control method is conducted. To speed up the computational time, a heuristic algorithm based on Genetic Algorithm is proposed for genetic networks of large size.</p

Re-Generating Research Partnerships in Early Childhood Education: A Non-Idealized Vision

This chapter provides a challenge to positivist notions of partnership in early childhood education, and instead proposes a re-generative posthumanist perspective, based on relationality of partnerships. Specifically, the chapter addresses the troubles and struggles inherited in research partnerships through a non-idealized vision of research partnerships. It experiments with the notions of regenerating ‘change’ and regenerating ‘relationality’. It also addresses the multi-layered aspects of knowledge-in-the-making; non-innocent relations; difficulties of thinking change in research; and the potentialities of conflict and dissension. However, no certainties and closures about research partnerships are provided
