Viral Becomings:From Mechanical Viruses to Viral (Dis)Entanglements in Preventing Global Disease
This paper explores the contribution of an ethos of (dis)entanglement arising from quantum thought to interpreting and (re)acting on the current global pandemic of Covid-19. The Covid-19 pandemic is giving rise to a world of pandemic separation, in which infection barriers such as masks, disinfection, social distancing, and isolation may be necessary in the immediate moment of avoiding sickness and death. However, these exclusionary and short-term response mechanisms do not address the larger question relating to global interspecies living, which in its current dynamic is increasingly giving rise to newly emerging infectious diseases such as Covid-19. The Covid-19 pandemic is showing that the health of human beings is deeply entangled with that of other species and places. However, it is also showing the limits to the mechanistic ontology driving modern public health thinking. I build on the work by political ecologists of health and biosocial scholars, especially Frost's concept of biocultural emergence and her engagement with ontological plurality in the human subject, to make the case for a different global politics of disease in preventing the emergence of infectious disease
Another Way of Seeing: Ecological Existentialism in Cortázar’s “Axolotl”
This study provides a reading of Julio Cortázar’s short story “Axolotl” through the dual lenses of ecocriticism and mid-century existentialism. Specifically, the critical perspective of this work is inspired by the writings of existentialist philosopher Jean-Paul Sartre, and German biologist Jakob Johann von Uexküll. Such an interdisciplinary approach is intended to articulate a unique ecological perspective known as environmental existentialism. This critical approach not only acknowledges the longstanding influence that the existentialist movement has had on environmental scholarship, but also suggests that existentialist concepts are especially relevant to our contemporary ecological moment, and thus should continue to be employed in current ecological discourse. The primary locus of critical attention in this work centers on Sartre’s theory of the Look, Uexküll’s notion of the search tone, and Cortázar’s emphasis on suffering. These concepts are examined in concert to suggest that the correlations between the dominant issues of existentialist thought and our contemporary moment ought to signal to readers the existential threat that the age of the Anthropocene poses, as well as the value of reading texts both old and new through the lens of existential ecocriticism
Riding the Shi:from infection barriers to the microbial city
How can a microbial approach to global health security protect life? Contemporary infection control mechanisms set the human and the pathogenic microbe against each other, as the victim versus the menace. This biomedical polarization persistently runs through the contemporary dominant mode of thinking about public health and infectious disease governance. Taking its cue from the currently accepted germ theory of disease, such mechanisms render a global city like Hong Kong not only pervasively “on alert” and under threat of unpredictable and pathogenic viruses and other microbes, it also gives rise to a hygiene and antimicrobial politics that is never entirely able to control pathogenic circulation. The article draws on recent advances in medical microbiology, which depart from germ theory, to invoke an ecological understanding of the human-microbe relation. Here, while a small number of viruses are pathogenic, the majority are benign; some are even essential to human life. Disease is not just the outcome of a pathogenic microbe infecting a human host but emerges from socioeconomic relations, which exacerbate human-animal-microbial interactions. In a final step, the article draws on Daoist thought to reflect on the ways that such a microbial understanding translates into life and city dwelling

ROLES AND INTERPLAY OF ION TRANSPORT PROTEINS IN PLASTID PHYSIOLOGY
Ion channels and transporters are present in membranes of all living cells. As integral membrane proteins, they can sense and transduce the chemical environment to other cells and cell compartments. Additionally, ion transport proteins affect membrane voltage, balance substrate and water flux, are involved in signaling processes, and help protect cells from damage. In the chloroplast, the plant organelle harboring the photosynthetic apparatus, knowledge about the physiological role of many ion transport proteins is limited. Due to the importance of photosynthesis, it is necessary to uncover the full potential of chloroplast transport proteins, particularly those that use the ion potassium (K+) as substrate. K+ is highly abundant in cells and fulfills many roles in plant and plastid physiology. This dissertation describes the roles of transport proteins inside chloroplasts of Arabidopsis thaliana. We characterized novel proteins, adding to the chloroplast transportome, discovered unidentified connections between protein families, and revisited the localization and function of another previously described transporter. First, we investigated putative K+-permeable ion channels in the chloroplast envelope membrane. Even though the mechanism has been described before, the molecular identity of these proteins was unknown. Candidate proteins PLASTID ENVELOPE ION CHANNEL1/2 (PEC1/2) are localized to the plastid envelope and exhibit K+-permeability but are most likely not required for K+ homeostasis since pec1pec2 mutants displayed no apparent phenotypic abnormalities. However, we found that PEC1/2 play a crucial role in chloroplast Ca2+ signaling. Secondly, we examined the interplay of two different ion transport proteins implicated in osmoregulation of plastids, K+-EFFLUX ANTIPORTER1 (KEA1) and MscS-LIKE2 (MSL2). The simultaneous lack of both proteins in kea1msl2 mutants resulted in novel phenotypic anomalies, pointing to a concerted function of both proteins. Finally, we studied the localization and role of putative envelope Na+:H+ ANTIPORTER NHD1 and found evidence for a thylakoid membrane localization in different approaches. In addition, investigations of nhd1 mutants revealed the importance of the carrier NHD1 in acclimation to fluctuating light conditions. Overall, this dissertation advanced our understanding of chloroplast ion transport proteins, subcellular Ca2+ signaling, and chloroplast homeostasis
Human security assemblages in global politics: the materiality and instability of biopolitical governmentality in Thailand and Vietnam
This thesis investigates the implications of human security on global politics. While it adopts a Foucauldian analytics of governmentality and biopolitics, the thesis differs from
biopolitical accounts of human security. These accounts tend to reduce human security to a coherent, totalizing, and inadvertently successful mode of governance, deemphasizing its situatedness and instability. In contrast, by complementing the Foucauldian approach to
the study of human security with a Deleuzian lens of machinic assemblage in which materiality is particularly emphasized, the thesis argues that the governmental logic of
human security gives rise to a multiplicity of open-ended vernacular assemblages and associated orders of governance. Though these assemblages are particular, messy,
contingent systems which vacillate, undermine themselves, clash and hybridize with surrounding assemblages, this does not render them ineffective. When the object of analysis is the global, a focus on the materiality of events helps to explore how the global is localized. A focus on materiality opens up the opportunity to explore how the local
materializes. This interplay between localizations and materializations disrupts the logics that underlie governmental processes. In this way, the thesis demonstrates how the intransigence of life constantly escapes and readjusts the biopolitical imperative.
Empirically, the thesis traces the way human security materializes as a situated governmental strategy in emerging assemblages for managing pathogenic and illicit
circulations relating to global migrant communities in Thailand and Vietnam. It shows the way the intricate and productive as well as destructive interplay of human and nonhuman elements inherent to the assemblages helped to constitute two vernacular orders of human security and associated political subjectivities
Ethics in a Quantum World
This forum invites a reflection on how we may understand ethics in global studies in light of the growing debate on thinking through quantum for the social sciences and humanities more broadly. Quantum principles such as entanglement and indeterminism challenge the notions of individuality and subjectivity and the validity of universal principles as sufficient guidelines for agency, all notions that constitute the foundations of modern deontological ethics. Science is not a separate sphere of society. Its concepts migrate across “disciplines” and end up constituting languages, accepted methodologies, and worldviews. The contributors to this special issue investigate how the shift from a Newtonian metaphysics to a quantum metaphysics may offer conceptual tools for transforming our understanding of causality, self and otherness, the human and the nonhuman, and how we may consequently live together in the world and act ethically in it
