Exploring Food System Transformations in Spain (1980-2021)
èng In this PhD Thesis, I examine the transformations of the Spanish food system from 1980 to the present, focusing on its socioeconomic structural changes and their impacts on sustainability and social equity. My research is grounded in agrarian history and political economy approaches, and also incorporates insights from ecological and feminist economics. The first and third Chapters are empirical in nature. Based primarily on data from Spanish national accounts, the results demonstrate the increasing integration of the Spanish agri-food system into the global one and the growing dependence of agriculture on external inputs. They also reveal a sharp decline in the agrarian population along with the increase in the share of salaried work. This is explained by the reduction in the number of farms throughout the period, particularly small family farms, which also show an aging process of their holders. The decline of the agrarian income has been a major determinant in this path. The combination of these trends jeopardizes the present and future reproduction of Spanish agroecosystems. I also examine the evolution of food expenditure of Spanish households, as a first exploration of the food cost in the reproduction of labouring population. The results show a halt in the reduction of its weight, but further research is needed for a definitive conclusion. Additionally, the results suggest an increasing inequality in the distribution of value added along the agri-food chain. In the second Chapter, I develop a research framework to investigate food systems at a national level, and particularly their role in the reproduction mechanisms of the capitalist system in which they are embedded, based on the approaches of the food regimes, social metabolism, and surplus/reproduction. This framework has helped me to interpret the results from the first and third Chapters from a more comprehensive approach. The framework includes six dimensions encompassing 36 elements linked through six key cross-cutting connections
Revitalising Gija: Developing Genre-based Documentation and Description for Community Language Programs
Gija is a language spoken in the east Kimberley region of Western Australia. Based on a number of
indicators of language vitality, it has been classified as Severely Endangered or Moribund. This
research undertakes description of Gija, applying Systemic Functional Linguistic (SFL) typology and
genre theory in the context of supporting the maintenance of this endangered Australian language.
Many linguists now agree that if linguistic scholarship is to contribute directly to language
revitalisation processes, it must consider language in use and in its cultural context. SFL, in its
orientation towards meaning and its metafunctionally diversified, stratified model of language
provides theoretically informed principles for making such a contribution.
This study takes texts highly valued in the Gija community and used in language education as its
data. It recognises three significant genres - the Ngarranggarni story, plant usage report and mantha.
Applying a stratified model of text in context, the analyses investigate the patterns of language choice
from a ‘top-down’ perspective. That is, chapters begin with genre, looking at how texts are staged to
fulfill their social purpose and what configurations of register variables (known as field, mode and
tenor) underpin each text. Within genre stages meanings are realised as unfolding phases, realised
in turn as patterns of choice from discourse semantic systems. Finally, each genre becomes the way
in to discussing how the verbal group in Gija contributes to ideational, textual and interpersonal
meaning at clause, group and word rank.
By taking these insights and recontextualising them in teacher training, Gija educators can be
supported to bring their knowledge about Gija to consciousness, supporting their growing confidence
as teachers of their own language. This study could also be utilised to develop linguistically informed
resources for school and community-based Gija language teaching programs in the future
Machine Learning Algorithm for the Scansion of Old Saxon Poetry
Several scholars designed tools to perform the automatic scansion of poetry in many languages, but none of these tools
deal with Old Saxon or Old English. This project aims to be a first attempt to create a tool for these languages. We
implemented a Bidirectional Long Short-Term Memory (BiLSTM) model to perform the automatic scansion of Old Saxon
and Old English poems. Since this model uses supervised learning, we manually annotated the Heliand manuscript, and
we used the resulting corpus as labeled dataset to train the model. The evaluation of the performance of the algorithm
reached a 97% for the accuracy and a 99% of weighted average for precision, recall and F1 Score. In addition, we tested
the model with some verses from the Old Saxon Genesis and some from The Battle of Brunanburh, and we observed that
the model predicted almost all Old Saxon metrical patterns correctly misclassified the majority of the Old English input

How vaccines come to matter: A feminist STS encounter with the politics of vaccines
This thesis examines the relationship between bodies, politics, and vaccines. I am writing in the context of a pandemic during which vaccines are at the centre of public, political, scientific and media attention. The pandemic has quite clearly exposed the uncertainties and complexities of vaccine research in practice, and the inadequacy of understanding scientific practices as smooth, universalised and disentangled from social dynamics. This thesis tells the story of vaccines as political material encounters. This framing problematises the technological hubris that reduces medical accomplishments to purely biological terms, and questions reinvigorated calls to separate science from politics.
Informed by a science and technology studies (STS) perspective and more specifically feminist sensitivities of STS work, I point to the entangled nature of social and scientific events, and to the non-universality of the subject of medical research. The central claim that I make, and work with,
across this thesis is that the indeterminacy of vaccines – their social, political and material contingency – is in fact key to the way in which vaccines work. At a time of heightened concern around the public uptake of vaccines, where heroic narratives of the ways in which vaccines work have come to dominate public discourse, in this thesis I explore the grounds for a humbler disposition toward vaccination. I argue that, understanding the situated material configuration of vaccines and their broader social and political co-production provides a vantage point for reassessing the conditions that enable vaccines to work. This insight allows me to claim that vaccines only exist through the material relations they emerge from. I call these relations ‘encounters’ and my exploration of the indeterminacies of vaccines as a practice of ‘encountering’. Rather than ask what vaccines ‘are’, my thesis askes how vaccines come to matter, how they relate to, and at the same time make and enact, specific ideas of bodies, immunity, health and collectivity.
I analyse how vaccines encounter nature through the pathogens they are developed to build protection from; how they encounter multispecies bodies in the laboratory practices that produce them; how vaccines encounter the immune system through the phenomenon of immunological memory; and finally, how vaccines encounter communities of bodies through the phenomenon of herd immunity. For each of these encounters, first I consider how these relations are often understood as neutral, fixed, and predetermined outcomes. Then, a further consideration of their material intricacies and the meanings they enact allows me to expose the political and ethical stakes of these arrangements. Understanding vaccines as encounters, focusing on the situated, material, relational condition of their enactments, will open up the possibility to propose different configurations of these encounters and alternative political and ethical sensibilities related to vaccines as relational technologies of bodies, health and community
The universe without us: a history of the science and ethics of human extinction
This dissertation consists of two parts. Part I is an intellectual history of thinking about human extinction (mostly) within the Western tradition. When did our forebears first imagine humanity ceasing to exist? Have people always believed that human extinction is a real possibility, or were some convinced that this could never happen? How has our thinking about extinction evolved over time? Why do so many notable figures today believe that the probability of extinction this century is higher than ever before in our 300,000-year history on Earth? Exploring these questions takes readers from the ancient Greeks, Persians, and Egyptians, through the 18th-century Enlightenment, past scientific breakthroughs of the 19th century like thermodynamics and evolutionary theory, up to the Atomic Age, the rise of modern environmentalism in the 1970s, and contemporary fears about climate change, global pandemics, and artificial general intelligence (AGI).
Part II is a history of Western thinking about the ethical and evaluative implications of human extinction. Would causing or allowing our extinction be morally right or wrong? Would our extinction be good or bad, better or worse compared to continuing to exist? For what reasons? Under which conditions? Do we have a moral obligation to create future people? Would past “progress” be rendered meaningless if humanity were to die out? Does the fact that we might be unique in the universe—the only “rational” and “moral” creatures—give us extra reason to ensure our survival? I place these questions under the umbrella of Existential Ethics, tracing the development of this field from the early 1700s through Mary Shelley’s 1826 novel The Last Man, the gloomy German pessimists of the latter 19th century, and post-World War II reflections on nuclear “omnicide,” up to current-day thinkers associated with “longtermism” and “antinatalism.” In the dissertation, I call the first history “History #1” and the second “History #2.”
A main thesis of Part I is that Western thinking about human extinction can be segmented into five distinction periods, each of which corresponds to a unique “existential mood.” An existential mood arises from a particular set of answers to fundamental questions about the possibility, probability, etiology, and so on, of human extinction. I claim that the idea of human extinction first appeared among the ancient Greeks, but was eclipsed for roughly 1,500 years with the rise of Christianity. A central contention of Part II is that philosophers have thus far conflated six distinct types of “human extinction,” each of which has its own unique ethical and evaluative implications. I further contend that it is crucial to distinguish between the process or event of Going Extinct and the state or condition of Being Extinct, which one should see as orthogonal to the six types of extinction that I delineate. My aim with the second part of the book is to not only trace the history of Western thinking about the ethics of annihilation, but lay the theoretical groundwork for future research on the topic. I then outline my own views within “Existential Ethics,” which combine ideas and positions to yield a novel account of the conditions under which our extinction would be bad, and why there is a sense in which Being Extinct might be better than Being Extant, or continuing to exist

Higher-Order Logical Pluralism as Metaphysics
Higher-order metaphysics is in full swing. One of its principle aims is to show that higher-order logic can be our foundational metaphysical theory. A foundational metaphysical theory would be a simple, powerful, systematic theory which would ground all of our metaphysical theories from modality, to grounding, to essence, and so on. A satisfactory account of its epistemology would in turn yield a satisfactory epistemology of these theories. And it would function as the final court of appeals for metaphysical questions. It would play the role for our metaphysical community that ZFC plays for the mathematical community.
I think there is much promise in this project. There is clear value in having a shared foundational theory to which metaphysicians can appeal. And there is reason to think that higher-order logic can play this role. After all, it has long been known that one can do math in higher-order logic. And there is growing reason to think that one can do metaphysics in higher-order logic in much the same way. However, most of the research approaches higher-order logic from a monist perspective, according to which there is 'one true' higher-order logic. And in the midst of the enthusiasm, metaphysicians seem to have overlooked that this approach leaves the program susceptible to epistemological problems that plague monism about other areas, like set theory.
The most significant of these is the Benacerraf Problem. This is the problem of explaining the reliability of our higher-order-logical beliefs. The problem is sufficiently serious that, in the set-theoretic case, it has led to a reconception of the foundations of mathematics, known as pluralism. In this dissertation I investigate a pluralist approach to higher-order metaphysics. The basic idea is that any higher-order logic which can play the role of our foundational metaphysical theory correctly describes the metaphysical structure of the world, in much the way that the set-theoretic pluralist maintains that any set theory which can play the role of our foundational mathematical theory is true of a mind-independent platonic universe of sets. I outline my view about what it takes for a higher-order logic to play this role, what it means for such a logic to correctly describe the metaphysical structure of the world, and how it is that different higher-order logics which seem to disagree with each other can meet both of these conditions.
I conclude that higher-order logical pluralism is the most tenable version of the higher-order logic as metaphysics program. Higher-order logical pluralism constitutes a radical departure from conventional wisdom, requiring a significant reconception of the nature of validity, modality, and metaphysics in general. It renders moot some of the most central questions in these domains, such as: Is the law of excluded middle valid? Is it the case that necessarily everything is necessarily something? Is the grounding relation transitive? On this picture, these questions no longer have objective answers. They become like the question of whether the Continuum Hypothesis is true, according to the set-theoretic pluralist. The only significant question in the neighborhood of the aforementioned questions is: which metaphysical principles are best suited to the task at hand

Where there are no Footprints: An Ethnography of Contemporary Art in Kolkata
This dissertation is an ethnographic exploration of contemporary art in Kolkata. It closely follows several individual artists and art groups who endeavour to defy established conventions and create new works of art. Yet, confronted with a new work of art, a doubt sets in. Wasn’t this made before? Can we be sure that it’s not a copy? The doubt of novelty and originality has always troubled the visual arts, and was particularly pronounced in (post)colonial Calcutta, where works were condemned by some as belated repetitions of European modern art. Convictions of belatedness have been successfully debunked, but with the emergence of ‘contemporary’ art the doubt of novelty emerges yet again. To understand the predicament of artistic novelty this dissertation unfolds a cyclical ritual theory of contemporary art that includes the practices surrounding the artwork, while not forgetting the artwork itself – an analysis that involves the entire set of practices implicated in the production, exhibition, circulation, and preservation of art. This theory is subsequently applied to the field of contemporary art in Kolkata. The ethnographic chapters focus on the tension between artistic attempts to make new works of art and the various limitations that artists encounter; artists are not just caught up in artistic conventions, but are simultaneously impeded by limited economic means and trapped in a peripheral position where they always seem to lag behind, caught up in a city that doesn’t seem to live up to its own history. Yet, by making ambiguous works that resonate with the city in various ways, artists defy conventions, bypass limitations, and offer moments in which the world can be experienced anew
