    This thesis project takes place at a time of increasing focus upon two-year-old children and the words they speak. On the one hand there is a mounting pressure, driven by the school readiness agenda, to make children talk as early as possible. On the other hand, there is an increased interest in understanding children’s communication in order to create effective pedagogies. More-than-words (MTW) examines an improvised art-education practice that combines heterogenous elements: sound, movement and materials (such as silk, string, light) to create encounters for young children, educators and practitioners from diverse backgrounds. During these encounters, adults adopt a practice of stripping back their words in order to tune into the polyphonic ways that children are becoming-with the world. For this research-creation, two MTW sessions for two-year-old children and their carers took place in a specially created installation. These sessions were filmed on a 360˚ camera, nursery school iPad and on a specially made child-friendly Toddler-cam (Tcam) that rolled around in the installation-event with the children. Through using the frameless technology of 360˚ film, I hoped to make tangible the relation and movement of an emergent and improvised happening and the way in which young children operate fluidly through multiple modes. Travelling with posthuman, Deleuzio-Guattarian and feminist vital material philosophy, I wander and wonder speculatively through practice, memory, and film data as a bag lady, a Haraway-ian writer/artist/researcher-creator who resists the story of the wordless child as lacking and tragic; the story that positions the word as heroic. Instead, through returning to the uncertainty of improvisation, I attempt to tune into the savage, untamed and wild music of young children’s animistic onto-epistemologies

    This doctoral thesis is based on new unpublished material excavated, prepared and studied by the author. The thesis is structured in seven chapters, including an introductory chapter and a final chapter with conclusions and general considerations. The main objectives of this thesis are (1) to provide new paleobotanical data from the Jurassic records of the northern Iberian Peninsula; (2) prospecting and excavation of new Jurassic deposits; (3) Study and identify the different fossils collected in the selected deposits; (4) Establish from the fossil record the reconstruction of the paleoclimatic and paleoenvironmental conditions during the Jurassic in the area; (5) develop paleoecological contextualization including the study of plant-insect interactions. The first chapter deals with the state of the art of Jurassic paleobotany and plant-insect interactions in the Iberian Peninsula and presents the bases to contextualize the following chapters. The second chapter deals with the discovery of a new flora with plant-insect interactions from the Middle Jurassic located on a volcanic island far from the mainland, called Isla Camarena. The third chapter describes the palynological association of the aforementioned Middle Jurassic (paleo) island of Camarena. This chapter identifies a new palynological assemblage, including its palynostratigraphic analyses, which improves the dating of this unique site and also attempts to reconstruct the plant communities that inhabited this oceanic island, their possible colonization strategies, and the dispersal capabilities of some palynomorphs found on the island (paleo) The fourth chapter describes a new species of liverwort: Ricciopsis asturicus sp. nov. found in the Upper Jurassic (Kimmeridgian) of the Lastres Formation in Asturias, constituting the earliest evidence of the Ricciaceae Family in the Iberian Peninsula. The taxonomy of this group is also discussed, proposing the deletion of an earlier species of Ricciopsis. In addition, the paleogeographic distribution of the genus is interpreted, as well as its paleoecological implications. The fifth chapter describes and identifies the palynomorphs found in different sections of the Asturian Coast of Dinosaurs, discussing the palynostratigraphic implications for the formation. In addition, the botanical affinities of the palynomorphs are taken into account, presenting the reconstruction of the plant communities that formed the landscape of the Coast of the Dinosaurs of Asturias during the Kimmeridgian, and showing an approximation to the paleoclimatic and paleoenvironmental conditions of this formation. The sixth chapter consists of new flora and insect remains from a Late Jurassic hydrothermal paleoenvironment (J/K boundary). This flora was found in the Aguilar Formation and grew in a unique environment of hot springs. The seventh chapter evaluates the new findings and their implications for the knowledge of the Jurassic paleobotany of the Iberian Peninsula, as well as a projection of the future lines of research opened with the new contributions.Esta tese de doutoramento baséase en novo material inédito escavado, elaborado e estudado polo autor.

    Elements, Government, and Licensing: Developments in phonology

    Get PDF
    Elements, Government, and Licensing brings together new theoretical and empirical developments in phonology. It covers three principal domains of phonological representation: melody and segmental structure; tone, prosody and prosodic structure; and phonological relations, empty categories, and vowel-zero alternations. Theoretical topics covered include the formalisation of Element Theory, the hotly debated topic of structural recursion in phonology, and the empirical status of government. In addition, a wealth of new analyses and empirical evidence sheds new light on empty categories in phonology, the analysis of certain consonantal sequences, phonological and non-phonological alternation, the elemental composition of segments, and many more. Taking up long-standing empirical and theoretical issues informed by the Government Phonology and Element Theory, this book provides theoretical advances while also bringing to light new empirical evidence and analysis challenging previous generalisations. The insights offered here will be equally exciting for phonologists working on related issues inside and outside the Principles & Parameters programme, such as researchers working in Optimality Theory or classical rule-based phonology

    Multi-trophic Interactions and Long-term Volunteer Collected Data: Networks of plant-caterpillar-parasitoid interactions across time, space, and a changing climate

    Get PDF
    The preservation of ecological complexity is an important goal for ecologists as communities respond to global change. Inherent to these efforts is the quantification and evaluation of the multiple dimensions of biodiversity, including well studied metrics of taxonomic, phylogenetic, and functional diversity. Studies on multi-trophic systems have primarily focused on taxonomic diversity, yet recent efforts have highlighted the importance of examining an underutilized biodiversity metric: interaction diversity, or the richness and abundance of the unique links connecting species. My dissertation research contributes to understanding spatial and temporal variation in the diversity of plant-caterpillar-parasitoid interactions. A central theme of my dissertation research is the use of long-term citizen science data from sites across the Americas to understand how interaction diversity changes across latitudinal, climate, disturbance, and seasonal gradients. My research in tropical forests documented the impacts of climate change. I found increases in extreme precipitation events caused reductions in interaction and species diversity with associated losses in an important ecosystem function: Biological control of herbivores by their natural enemies. In a temperate fire-adapted forest, I provided evidence for the scale-dependent nature of interaction diversity and its implications for how diversity is maintained in frequently disturbed systems. To understand spatial and temporal variation in interactions, I evaluated patterns in the beta-diversity of interactions and its components. Using this methodology, I found evidence of latitudinal patterns in the turnover of interactions, providing support that interactions are more variable in tropical than temperate regions. In the Brazilian Cerrado and Yucatan Peninsula, Mexico, I found seasonal variation in interaction diversity is primarily a consequence of seasonally constant species rewiring their interactions rather than seasonal differences in species composition. Finally, an important goal for ecology is to develop effective methods that increase the public's awareness and action toward biodiversity conservation. I fielded over 300 citizen scientists on research expeditions that contribute to the collection and rearing of these long-term data and administered surveys to understand the impact of different team models. Based on these surveys, multiple team models are effective for achieving diverse objectives and corporate teams are particularly valuable for sustainability partnerships. Together, this body of research provides evidence that interaction diversity uniquely contributes to broad patterns of biodiversity and ecosystem structure. Further, novel partnerships with various citizen science team models are an effective and efficient method to engage a diverse public audience interested in the preservation of biodiversity

    Developing a predictive geospatial habitat model for a rare species of salamander in Tennessee: a case study for the green salamander (Aneides aeneus)

    Get PDF
    Green Salamanders (Aneides aeneus; Cope and Packard 1881) are a secretive and cryptic species of salamander that can be relatively difficult to detect, due to their occupation of arboreal habitats. The incorporation of geospatial tools is critical in developing models that can be used to predict undocumented locations in Tennessee and elsewhere. Locating the species in Tennessee was accomplished through a total of 18 localities and with that, several habitat characteristics were able to be identified including, but not limited to: appropriately shaded and structured rocks, typical fauna co-occurring within the area, and general topography of the area. Of the 91.8% of sites that were deemed to have suitable habitat, 40% of those had positive presence, the remaining 60% is indeterminate for presence at this time as more field visits should be conducted in the future

    Children's encounters with urban woodlands, digital technologies and materialities

    Get PDF
    This research considers children’s encounters and learning with ‘natures’, places and digital technologies. It is situated within an urban woodland in Birmingham and is a collaborative project working with two primary schools participating in six-months of walking and filming events, website creation and creative workshops. Drawing on embodied, multi-sensory and socio-material approaches to children’s geographies and interdisciplinary environmental education research, it works with the ‘technique’ of research-creation to explore children’s learning with ‘natures’ and digital platforms such as YouTube. It also examines creative responses to the more-than-human, including water, weather, soils, trees, mud, bricks and minerals. Through inclusion of the GoPro wearable technology as part of the research assemblage, the project draws on notions of the entanglement of the digital and physical in techno-naturecultures (following Haraway’s naturecultures and Latour’s common worlds), arguing for the productive inclusion of the digital within environmental education practices

    A defence of Isaacson's thesis, or how to make sense of the boundaries of finite mathematics

    Get PDF
    Daniel Isaacson has advanced an epistemic notion of arithmetical truth according to which the latter is the set of truths that we grasp on the basis of our understanding of the structure of natural numbers alone. Isaacson's thesis is then the claim that Peano Arithmetic (PA) is the theory of finite mathematics, in the sense that it proves all and only arithmetical truths thus understood. In this paper, we raise a challenge for the thesis and show how it can be overcome. We introduce the concept of purity for arithmetical theories: an arithmetical theory is pure when it only proves arithmetical truths. Then, we argue that, under Isaacson's thesis, some PA-provable truths—including transfinite induction claims for infinite ordinals and consistency statements—are seemingly not arithmetical in Isaacson's sense, and hence that Isaacson's thesis might entail the impurity of PA. Nonetheless, we conjecture that the advocate of Isaacson's thesis can avoid this undesirable consequence: the arithmetical nature, as understood by Isaacson, of all contentious PA-provable statements can be justified. As a case study, we explore how this is done for transfinite induction claims with infinite ordinals below ε_0. To this end, we show that the PA-proof of such claims exclusively employs resources from finite mathematics, and that ordinals below ε_0 are finitary objects despite being infinite
