Full textAbstract:
The present manifests in a nebulous soup of imagination, and is a state of unbounded curiosity. It is a weaver who stitches what-has-been to what-will-be-has-been. My work prods an American sense of progress, and the effects it has on shaping our future from its seat in the present as it attempts to evade history.

Full textAbstract:
Increases of temperature in the range from 8 to 18°C in vivo, significantly enhanced the dry weights of lateral rhizomes, roots and shoots. At the higher temperatures dry weight production was often seen to decrease. Decreases in irradiance from 100 to 50 per cent in vivo, produced significant decreases in the dry weights of lateral rhizomes, roots and shoots. In contrast, the numbers of lateral rhizomes, tubers and shoots were largely unaffected by temperature and irradiance treatments. Day length treatments of 8 to 16 hours light in a 24 hour period in vivo produced few significant changes in either the dry weights or numbers of plant parts produced. However, day length had a strong influence over the time of flowering. For maximum rhizome production a temperature of between 13 and 18°C, a high irradiance and a short day length were required. Increases of temperature in the range 8 to 18°C in vitro, caused significant increases in the number of lateral rhizomes and shoots produced. At the highest temperature the numbers produced often decreased. The number of roots produced was unaffected by temperature. Decreases in irradiance from 100 to 25 per cent and increases in day length from 8 to 20 hours light in a 24 hour period, produced no significant changes in the number of lateral rhizomes, roots or shoots produced in vitro. Low irradiance, however, caused etiolation of the shoots. For a good multiplication rate the requirements for the culture environment were a temperature of 15°C, an irradiance of 5 Win- 2 with a day length of 8 hours of light in a 24 hour period. The presence or absence of tubers and damage suffered by `splits' prior to planting were found to be important factors in the establishment of plants in vivo. Subculture of rhizome explants without aerial shoot or rhizome apices and of rhizome explants divided into single internodes with or without aerial shoots, enhanced the rhizome multiplication rate. Addition of the plant growth regulators triiodobenzoic acid, thidiazuron, α-naphthaleneacetic acid, gibberellic acid and paclobutrazol to culture media, with and without BAP, caused no significant changes in the numbers of lateral rhizomes, shoots or roots produced. However, paclobutrazol produced changes in explant morphology, i.e. shoot size was reduced and the diameter of roots was increased.

Perruchon, Véronique. "L'oeuvre théâtrale d'André Engel : machine et rhizome." Thesis, Paris 3, 2009. http://www.theses.fr/2009PA030125.
Full textAbstract:
Cette thèse explore et analyse l’œuvre théâtrale d’André Engel, metteur en scène français atypique. Depuis 1972, il travaille avec une équipe de création constituée des dramaturges Bernard Pautrat puis Dominique Muller, du décorateur Nicky Rieti et de l’éclairagiste André Diot. André Engel a d’abord créé ses spectacles dans des lieux inédits : haras, usine désaffectée, ancienne mairie, hangar, donnant naissance à des « Objets Théâtraux Non Identifiés » qui marquèrent le théâtre des années soixante-dix et quatre-vingt ; formes que la nécessité de travailler dans les salles fit évoluer. Attaché à la question du spectateur, André Engel a, tout au long de son œuvre, proposé un renouvellement de son statut. De la création « hors les murs » au théâtre en salle, du « détour » par l’opéra à la tentation du cinéma, l’œuvre d’André Engel, constituée en cycles, est une véritable aventure théâtrale, une machine au rhizome complexe qui sort des repères connus. Nourri de philosophie allemande, d’influences deleuziennes et de lectures situationnistes, André Engel est venu au théâtre pour changer le monde. Il crée des événements, des expérimentations, des situations, proposant de nouveaux espaces-temps dans un acte de résistance et de reconquête du monde qui s’associe à une poésie de l’errance, du voyage et de la dérive. Machine de guerre contre « la société du spectacle », le théâtre est, pour André Engel, le lieu et le moyen d’un combat contre le monde aliéné, pour la reconquête de l’authenticité du réelThis thesis explores and analyzes the theatrical work of André Engel, an unconventional French stage director, working since 1972 with a team composed of dramatists Bernard Pautrat followed by Dominique Muller, designer Nicky Rieti and lighting designer André Diot, as a creative ensemble. André Engel staged his first performances in unusual places : a stud farm, a disused factory, a former town hall, a warehouse, giving birth to « Objets Théâtraux Non Identifiés » : landmarks in the theatre scene of the 70s and 80s. The need to work in conventional theatre brought with it in an evolution of his art. Throughout his work, André Engel proposes a new vision of the status of spectator. From « hors les murs » to more traditional venues, from incursions into opera to the temptations of cinema, these cycles in André Engel’s work are a true adventure in theatre, a machine with a complex rhizome which does not tread well-beaten paths. Nurtured by German philosophy, by the thought of Gilles Deleuze and influenced by readings of the Situationists, André Engel came to theatre in order to change the world. He creates events, experiments, situations, offering as an act of resistance, new dimensions in space and time : re-conquests of a world associated with the poetics of wandering, travelling, being adrift. As a machine for war against « la société du spectacle » as Guy Debord calls it, theatre for André Engel provides the perfect place and means for fighting against a world of alienation, for re-conquering the authenticity of the real

Campbell, Madeleine. "Translating Mohammed Dib : Deleuzean rhizome or Sufi errancy?" Thesis, University of Glasgow, 2014. http://theses.gla.ac.uk/5105/.
Full textAbstract:
There is a conceptual resonance between the rhizomatic habit in the world of plants and the perennial errancy in the (meta)physical world of man traversed by Mohammed Dib’s writing. In so far as reflective research and the practice of translation can ‘mirror’ the surface of their object, this project is a rhizomatic endeavour. It is a fragmentary journey into the desert, in search of the mysterious at’lāl, the trace of the sign, drawn and effaced and redrawn again by Mohammed Dib to reveal ephemeral truths about the self and its others. Dib’s focus migrates from early realist ‘socio-ethnographic’ novels in the 1950s to metaphysical explorations described by critics as ‘hermetic’, ‘mystical’ or ‘surreal’. The historical and the mystical, however, are two facets of the same inexorable acts of deterritorialization and reterritorialization in a precarious, often oneiric, universe. The ‘visions’ expressed in his poetics are couched in the elemental vocabularies of light and shadow, fire and water, space and duration and draw their substance from Sufi mystical scholars and poets. I posit that Dib’s nomadic contemporary writing arises from the place that lies between the sensible and the intelligible in Sufi mysticism, in a secular transposition of the Sufi Imagination: Dib neither constructs nor deconstructs. Rather, his singular style serves to hone an acutely experiential expression. Further, there is a sense in which each ouvrage is a heterotrope whereby his poetry and prose collections are inextricably embedded in each other, thus one is always in the middle of his universe. The ubiquitous entry point to this universe lies in the middle of his metaphorical desert, an aesthetic landscape stripped of idiocultural signification. Central to its lines of flight is the sign, both ephemeral and enduring, and what is enveloped in the sign is the non-signifying impact of its expression. I argue that Dib’s perennial re-assembling of ‘ces chaînes aux mailles d’acier qui sont mots’ (those chains with links of steel that are words) doesn’t so much ‘give rise to thought’ as ‘give rise to affect’.

Full textAbstract:
This dissertation is my articulation of the on-going dialogue between the art world and my own creativity. I achieve this by describing my digital project called Perceptions where in association with Kenneth Yuen, I designed a virtual gallery. The fundamental principle of this virtual gallery is a place where insider or outsider artists can hone their creative concepts, ideas, perceptions, feelings, aspirations, and tools. In this paper, I analyse some of the entries I have made to this virtual gallery. As a recognized Sydney artist I unfold my practice in an Exhibition held in the Ray Hughes gallery of Surrey Hills. I exhibited paintings in the innovative media of cast resin through linen, glass crystal, and welded steel. I analyse a selection of a piece exhibited in this commercial show. The study also includes a section of my personal dreams. I analyse and interpret the interaction between my conscious life as an artist and my unconscious personal material as a female sculptor, painter, and author of my practice. My objective has been to flesh out the vesicular and multifaceted layers of artistic expression that are generated through my work. To explain in words, the hidden world of the constructed meaning of the un-escaped personal dynamic of my art making. This exercise has implicated the articulation of personal disclosures and explicit interpretations of my artworks and dreams. The virtual gallery Perceptions, the commercial exhibition Pushing Up Daisies, and my recorded dreams together construct my contribution to the rhizome that consists between, within and beyond the visible world of art practice.

Browning, Helen. "Producing constellations : opening new documentary to rhizome theory." Thesis, Queensland University of Technology, 2004. https://eprints.qut.edu.au/15944/1/Helen_Browning_Thesis.pdf.
Full textAbstract:
Uncertainty is a documentary film about belief systems that human animals use to navigate the unknown and assign meaning to experiences. It acknowledges that we exist amidst the parameters of our own perceptual constructs. Our frameworks for navigation often range in degrees of openness to the unknown and to outside scrutiny.
I set out to explore these concepts through interactions with different individuals and social groups, each with their unique templates. I hoped to produce a stimulating film that engaged diverse audiences through diverse content.
Structural and stylistic considerations are paramount to my theoretical and post-production reflections on Uncertainty. Deleuze and Guattari's (1988) theory of rhizomes provides a good reference in terms of the cross-fertilisation of ideas, decentralised structure and different states of connection that I hoped to provoke through the film.
New documentary theory highlights a trend towards greater interaction between filmmaker, audience and subject (Bruzzi, 2000). This signals a growing understanding that striving for objectivity in documentary is redundant. Although it is a welcome development, discussion could be broadened in relation to filmmaker presence and interactivity, to include style and structure as modes of primary interaction for the filmmaker with the audience and subject. This exegesis approaches expanding the parameters for interaction to examples, such as Uncertainty, where the filmmaker is neither present in image or voice.
Texts that offer constellations of ideas, like a rhizome, provide an alternative to those following a more linear progression or centralised argument. Promoting greater connectivity and multiplicity in documentary is congruous with the current developments in communications and technologies.

Carneiro, Brito Elaine. "Le Rhizome patrimonial : analyser un mouvement hétérogène d'acteurs et de sens." Thesis, Avignon, 2018. http://www.theses.fr/2018AVIG1191/document.
Full textAbstract:
Cette thèse cherche à explorer les régimes de patrimonialisation des patrimoines, ou encore de patrimonialité des patrimoines, à partir des dynamiques sociales d’identification, de reconnaissance et de mise en valeur des objets dits « patrimoines ». Pour autant, s’opère une interprétation communicationnelle envisageant la compréhension d’une productivité discursive de la valeur patrimoniale. En d’autres termes, nous nous intéressons à la construction du sens patrimonial à partir du discours social. Ce travail s’efforce alors à décrire la patrimonialisation comme un mouvement qui se transforme et s’actualise à partir du discours des différents acteurs impliqués : détenteurs, amateurs, praticiens, associatifs, chercheurs, institutionnels, entre autres. C’est pourquoi nous considérons le discours depuis sa force illocutoire, ce qui nous permet de l’identifier comme une action qui vise « faire-faire » (Austin, [1962] 1970) ou encore « faire agir ». À cet égard, nous avons élaboré un dispositif méthodologique d’écriture webdocumentaire dans la finalité d’analyser sémio-pragmatiquement les différents discours collectés et provoqués lors des nos observations. Pour lors, notre dispositif méthodologique d’écriture webdocumentaire nous autorise la manipulation d’un ensemble de documents hétérogènes, c’est-à-dire l’organisation et la mise en forme, dans l’objectif d’exposer les possibles agencements d’acteurs et l’engendrement d’actions et de sens patrimoniaux. De cette manipulation, considérée comme l’« écriture intermédiaire » (Achard, 1994) de notre recherche, se manifeste peu à peu une conception « rhizomatique » (Deleuze et Guattari, 1980) de la patrimonialisation, où les acteurs sont tout à la fois agis et agissants de ce mouvement en perpétuelle transformation. L’idée d’un « Rhizome » des rhizomes patrimoniaux évolue durant les chapitres de ce mémoire de thèse nous révélant un mouvement patrimonial qui agence les acteurs et engendre les sens. Tel mouvement rhizomatique est notamment producteur de réflexions sur le passé « qui emprunte des signifiés au présent et ouvre les chemins pour le futur » (Mattos et Abreu, 2005)This thesis seeks to explore the regimes of patrimonialization of patrimonies, or patrimonial heritage, based on social dynamics of identification, recognition and enhancement of objects called "patrimonies". However, there is a communicational interpretation envisaging the understanding of a discursive productivity of the patrimonial value. In other words, we are interested in the construction of the patrimonial sense from the social discourse. Through the realization of two field surveys, in the city of Valença, in the region of Rio de Janeiro, Brazil, and in the "Territoire des Garrigues", in the Occitanie region, in France, we question how an object material or immaterial, is likely to become heritage through symbolic productions. A third observation, of distinct characteristics, was important for the development of this research: it is the "Ninth session of the Intergovernmental Committee for the Safeguarding of the Intangible Cultural Heritage", an event which took place in November 2014 in the UNESCO Headquarters, Paris. This work attempts to describe the heritage as a movement that is transformed and actualized from the discourse of the different actors involved: owners, amateurs, practitioners, associations, researchers, institutional, among others. This is why we consider the discourse from its illocutionary force, which allows us to identify it as an action that aims to "make-do" (Austin, [1962] 1970) or "to make action". In this respect, we have developed a methodological method of webdocumentary writing with the aim of analyzing semio-pragmatically the different discourses collected and provoked during our observations. This device gives us the initiative to produce and manipulate different formats of documents, such as audio-visual, sound, photographic and cartographic. Added to this production is the collection of a heterogeneity of documents produced by the actors themselves or by third parties. Therefore, our methodological method of webdocumentary writing allows us to manipulate this set of heterogeneous documents, that is to say the organization and formatting, with the aim of exposing the possible layouts of actors. and the begetting of actions and patrimonial meanings. From this manipulation, considered as the "intermediate writing" (Achard, 1994) of our research, is gradually emerging a "rhizomatic" conception (Deleuze and Guattari, 1980) of the patrimonialisation, where the actors are at the same time act and act of this movement in perpetual transformation. The idea of a "rhizome" of heritage rhizomes evolves during the chapters of this thesis revealing a patrimonial movement that organizes the actors and generates the senses. This rhizomatic movement is notably the producer of reflections on the past "which borrows from the signified in the present and opens the way for the future" (Mattos and Abreu, 2005). Patrimonialization described as a "Heritage Rhizome" becomes an integrated exercise in the public space, also allowing us to open up to other conceptions of public space
Esta tese tem por objetivo explorar os regimes de patrimonialização dos patrimônios, ou ainda de patrimonialidade dos patrimônios, através das dinâmicas sociais de identificação, de reconhecimento e de valorização dos objetos ditos “patrimônios”. No entanto, opera-se uma interpretação comunicacional com o propósito de compreender a produtividade discursiva do valor patrimonial. Em outras palavras, nós nos interessamos pela construção do sentido patrimonial à partir do discurso social. Este trabalho esforça-se em descrever a patrimonialização como um movimento que se transforma e se atualiza à partir do discurso dos diferentes atores envolvidos : detentores, amadores, praticantes, associativos, pesquisadores, institucionais, entre outros. Portanto, consideramos o discurso desde sua força ilocutória, o que nos permite identificá-lo como uma ação que busca “fazer-fazer” (Austin, [1962] 1970) ou ainda “fazer agir”. Para tanto, elaboramos um dispositivo metodológico de escrita webdocumentária afim de analisar semio-pragmaticamente os diferentes discursos coletados e provocados durante nossas observações. Logo, nosso dispositivo metodológico de escrita webdocumental nos autoriza a manipulação de um conjunto de documentos heterogêneos, ou seja a sua organização e edição, no intuito de expor possíveis associações entre os atores e o engendramento de ações e de sentidos patrimoniais. Desta manipulação, considerada como a “escrita intermediária” (Achard, 1994) da nossa pesquisa, se descobre pouco a pouco uma concepção “rizomática” (Deleuze e Guattari, 1980) de patrimonialização, onde os atores são ao mesmo tempo agidos e ativos de um movimento em constante transformação. A ideia de um “Rizoma” dos rizomas patrimoniais evolui durante os capítulos desta dissertação de tese nos revelando um movimento patrimonial que associa os atores e engendra os sentidos. Tal movimento rizomático é particularmente produtor de reflexões sobre o passado “que empresta significados para o presente e abre novos caminhos para o futuro” (Mattos e Abreu, 2005)

Full textAbstract:
Les années 1707 et 2011 marquent deux dates singulières du nationalisme écossais. Alors que l’union des royaumes d’Ecosse et d’Angleterre laisse place à la formulation d’une identité qui revendique la spécificité de l’Ecosse sans pour autant remettre en question le pouvoir central britannique, la victoire du « Scottish National Party » aux élections parlementaires symbolise la montée au pouvoir d’un parti qui revendique l’indépendance politique de l’Ecosse. Cette thèse se propose d’étudier la nature du sentiment national écossais et de ses représentations en analysant le rôle joué par le territoire national dans l’élaboration de l’idéologie nationaliste. Nous utilisons les concepts de la territorialité et du rhizome, comme définis respectivement par Jan Penrose d’une part et Gilles Deleuze et Félix Guattari d’autre part, afin de montrer que l’exploitation des représentations du sentiment national écossais donne naissance à des conceptions territoriales divergentes qui façonnent aujourd’hui encore l’identité nationale écossaiseThe years 1707 and 2011 hold a particular significance in the history of Scottish nationalism. Whereas the union of the kingdoms of Scotland and England gave way to the negotiation of a Scottish identity held within the larger structure of the British State, the victory of the "Scottish National Party" in the parliamentary elections symbolises the rise of a party claiming political independence for Scotland to a position of power. This thesis explores the nature of Scottish national sentiment and its representations while analyzing the role played by the national territory in the construction of nationalist thought. The concept of territoriality developed by Jan Penrose on the concept of rhizome as defined by Gilles Deleuze and Félix Guattari are used in order to demonstrate that harnessing the representations of the Scottish national sentiment spawned two diverging conceptions of the national territory which still shape Scottish national identity

Full textAbstract:
The aim of this degree project is to provide a description of the social movements that struggle against mega projects in Europe and of the relations between them. A body of literature on neoliberalism sets the context in which these struggles take place. The concept of rhizome, encompassing characters of multiplicity, heterogeneity, horizontality, is presented as a theoretical framework. These theoretical foundations are confronted with investigation on two levels. At a general level, internet-based research is carried out to map, at least in part, the constellation of movements involved. At a more focused level, participant observation is conducted in specific sites in order to grasp the ideas, discourses and meanings that colour the struggles. By setting the struggles in a wider political context and by experimenting alternative social and spatial practices, the rhizome of movements gives deeper significance to the contestation of mega projects and opens societal prospects.

Full textAbstract:
During the modern era, the urbanization of water has been facilitated by various privileged discourses, which valorize major engineering interventions for the sake of continued urban growth. This research examines discourse surrounding the 2-th Century proposal and construction of a reservoir near the then-tiny farming community of Grapevine, Texas, for the benefit of urban interests. I argue that urban interests produced Grapevine space as nothing more than a container for city water, by rendering meaningless any conception of space that was not directly articulated with urban economic networks. Modern discourse collapsed Denton Creek space from a watershed and landscape into a dimensionless node in the urban space of flows. In return, rural inhabitants were encouraged to progress and to modernize their own spaces: to become urban. Whereas urban discourse entails an implicit spatial imaginary of networks, I deploy the conceptual framework of settler colonialism to show that a core-periphery relationship remains relevant, and is not reducible to a network spatial ontology.

Full textAbstract:
Thesis advisor: Frances RestucciaWhat qualifies a work as distinctly modernist or postmodernist? Moving beyond the idea that modernism and postmodernism are primarily distinguishable on a temporal basis, D’Errico instead argues that the key difference between these two movements lies on a theoretical level. Grounded in a framework of contemporary theory put forth by Žižek, Lacan, Deleuze, and Badiou, D’Errico proposes that the Real-Symbolic relation manifests differently in modernist and postmodernist works; the structural paradigms of the torus and rhizome are helpful to illuminate this fundamental theoretical difference. Expanding on Žižek’s definitions of modernism and postmodernism (from Looking Awry ), D’Errico posits that a torus-shaped Real-Symbolic relation accords with modernism and that a rhizomatic Real-Symbolic relation accords with postmodernism. This interdisciplinary analysis of twentieth-century art mainly focuses on literature, but also invokes poetry, visual art, theatre, and film. Overall, D’Errico dissects the theoretical structures of The Sun Also Rises, Waiting for Godot, The Trial, White Noise, and Caché to qualify the alignment of each with either the modernist or postmodernist canon

Full textAbstract:
This thesis concerns itself with the nature of the visual medium and its growing importance to the contemporary world. It consists of two parts, one visual and the other written. The visual component consists of a 56 min. film entitled Letter to Eros. It is introduced in the written thesis as an example of a theoretical "rhizome" - a research paradigm based on what I have termed a "constructivist" research technique. This technique, as the label suggests, constructs the theoretical object, rather than deconstructing it textually through an analysis.
The written thesis also describes the genealogical elements of Letter to Eros and indicates how it relates to the content of the film and its rhizome-like structure. The main element of this genealogy is the influential work of Deleuze and Guattari, whose writing, in the two volumes of Capitalism and Schizophrenia, Anti-Oedipus and A Thousand Plateaus, describes, in some detail, the social relevance of rhizome-type logic to postmodern culture as a whole. In A Thousand Plateaus, Deleuze and Guattari find support for this kind of logic in Margaret Mead and Gregory Bateson's ethnographic work in Bali, where a similar logical arrangement is apparent in a range of Balinese drama and cultural practices, including trance dancing. The thesis argues that the formative elements of this "plateau" type logic are probably due to Margaret Mead and specifically her work on the mother-infant relationship. In this perspective, the schizological prescription which Deleuze and Guattari give us for the postmodern world may well be consistent with the ocular mother-child relationship theorized by Jacques Lacan in his Order of the Imaginary. This conclusion seems consistent with the ever increasing presence of images in the world today.
The last part of the written thesis seeks support for this ocular hypothesis by examining our changing relationship with visual exteriority since the invention of photography. It argues that as a consequence of the nexus between images and the flow of capital, more and more of what used to be the interiority of our thoughts is to be found in exteriority.

Full textAbstract:
The intelligent handling of waste is a pressing issue today. Up until the 19th century it had been however an integral part of societies especially when it comes to the waste generated by construction and demolition (Bahamon and Sanjines, 2010). After industrial revolution (1750-1850) which opened the gates of mass production and mass consumption followed and supported by two major forces of capitalism and the dramatic increase in world population, the generation of waste accelerated correspondingly and in a global scale. The mass extraction of natural resources on one hand (limited amount of natural resources), and the problems caused by waste landfilling and incineration such as pollution and diseases on the other hand, made us stop this linear extraction-to-waste trend and recognize recycling as a solution. Recycling chiefly addresses a sustainable approach to reduce the negative effects of waste and at the same time involves processing used materials (waste) into new products to prevent waste of potentially useful materials (Eco Cloud), however through recycling not only some energy has to be consumed to make this process run but also some portion of pollution would be generated as a side effect. What is more is that up until today recycling has been neither in many cases economically profitable nor has it been possible to recycle all the amount of waste. For instance In US- as the most consuming society on the planet Earth- only 34% of the municipal solid waste can be recycled and the rest ends up in either landfills or incinerators (EPA,2010). This project is to mainly focus on the definition of a rather comprehensive network (Network of Reuse) which sits right before recycling through which as much as possible of the total amount of waste could be directly absorbed back into the society (with minor changes in some cases) in different scales, the resultants of which would be claimed not to be only less energy consumption and less pollution caused through processing waste (as in recycling) but also avoiding a considerable amount of unrecycled materials from ending up in landfills and incineration. In fact the assumed network-which is simulated by the smart grid model- could be said to be a complementary section added to the existing trend today and is on no account against recycling. Like any other network, the network of reuse is based upon strategies, tools, and policies. The rhizomic growing structure of this network-that is in contrast to the tree structure of recycling- suggests a bottom up movement in handling waste and empowering people while the proposed time-line strategy is assumed to be moving from entertainment towards a coherent business network. In fact the project itself suggests the necessity of more bottom up structures to happen in our future planning. The entire project is highly founded upon research and could be applied in a variety of actual designs and concrete cases. Therefore, in this project no specific site is being addressed directly but the actual need for adding the supposed network is explored.

Full textAbstract:
Une recension exhaustive des références à la musique et au sonore montre l’importance de cet art dans la production philosophique de Gilles Deleuze et Félix Guattari. La présente recherche se concentre sur la position occupée par la pensée musicale de John Cage dans certains de ces textes. La période créative de Cage située entre 1939 et 1952, se focalise sur deux aspects principaux : la structure micro-macrocosmique caractéristique de ces premiers travaux, et les quatre éléments qui synthétisent alors pour Cage la composition musicale. Ces derniers sont considérés en rapport avec la théorie de la double articulation que Deleuze et Guattari reprennent de Hjelmslev ; les deux aspects renvoient au système des strates et de la stratification exposé dans Mille plateaux. La musique des décennies centrales de la production cagienne, à la lumière du passage de Mille plateaux où l’œuvre de Cage est mise en rapport avec le concept de « plan fixe sonore ». Une attention particulière est donnée à la manière dont Cage conçoit le rapport entre la durée et les matériaux sonores, et au degré variable de présence du hasard et de l’indétermination. Les compositions de cette période sont en outre vues en référence au concept deleuzo-guattarien de cartographie. Les derniers quinze ans de la production de Cage sont analysés à travers le concept de rhizome entendu comme théorie des multiplicités. La partition de Sylvano Bussotti qui figure au début de Mille plateaux ainsi que les travaux textuels et musicaux de Cage, les procédures compositionnelles des mésostiches, des parenthèses de temps qui créent une structure variable, et l’harmonie anarchique du dernier Cage sont également explicitésOn the basis of a exhaustive identification of the references to music and sound in the philosophical production of Gilles Deleuze and Félix Guattari, the present research concentrates on the position occupied by John Cage’s musical thought in a number of deleuzian texts. The first chapter analyses the works composed by Cage between 1939 and 1952, focusing on two principal aspects: the micro-macrocosmic structure that characterises his first works, and the four elements that resume Cage’s approach to composition in the period in question. The latter are considered in relation to Hjelmslev’s theory of double articulation as elaborated by Deleuze and Guattari; both aspects are referred to the system of strata and stratification found in A Thousand Plateaus. The second chapter is dedicated to the compositions of the central decades of Cage’s production, in the light of the passage of A Thousand Plateaus in which Cage is considered in relation to the concept of a “fixed sonorous plane”. Particular attention is given to the way in which Cage conceives the relation between duration and sound materials, and to the variable degree to which chance and indeterminacy are present. The compositions of this period are furthermore seen in reference to the deleuzo-guattarian concept of cartography. The last fifteen years of Cage’s production are studied through the theory of multiplicity and the concept of rhizome. The score composed by Sylvano Bussotti that appears at the beginning of A Thousand Plateaus is therefore considered, followed by an examination of Cage’s late textual and musical works, giving particular attention to mesostics, time brackets and variable structure, and anarchic harmony

With the rise of First Nations owned and created television content at the turn of the century, came a demand to see an accurate representation of Aboriginality that could look at Aboriginals as both here and modern. From 2003-2006, the first Aboriginal made and produced television series entitled Moccasin Flats, I argue, used modern day hip-hop discourse to both engage and dissect a host of complex issues facing modern day urban Aboriginal society. This research project mobilizes multiple methodologies; including: 1.) Eco’s code and sign function semiotic analysis, which operates to identify various hip-hop codes in the text; 2.)Hall’s method of articulation to look at how meaning is fixed in the discourse surrounding the show; and finally 3) Deleuze’s rhizomic approach to identity to see how the shows main characters are constructed in a way to highlight the paradoxical and undercut certain flirtations with essentialization. This three-tiered methodological process paints a picture of a new complex use of discourse to accentuate different facets of aboriginality that had previously been the sole product of dominant hegemonic institutions which relied on racist stereotypes. By dissecting how identity is formed on Moccasin Flats, I will show how aboriginal filmmakers construct a self-reflexive space where the character is perpetually in the process of ‘becoming’ and identity is always a site of negotiation.

Full textAbstract:
Thesis advisor: Kevin NewmarkThis thesis focuses on flora as metaphors and representations of identity in Simone Schwarz-Bart’s Pluie et vent sur Télumée miracle (1972), Xavier Orville’s Délice et le fromager (1977), and Maryse Condé’s Pays mêlé (1985). Within the context of the declining agricultural industry of the seventies and the eighties, these authors represent a new generation of writers from Guadeloupe and Martinique who add their own ambivalent landscape’s visions to those of Aimé Césaire’s Negritude and Édouard Glissant’s Creolization. As flora’s metaphors, trees and rhizomes reveal important aspects of the colonial world. Although the tree is a metaphor to unearth aspects of identity, does it have its own limitations in this colonial world? The theoretical basis for questioning the tree is rooted in Gilles Deleuze, Félix Guattari, and Édouard Glissant's rhizome theories. Chapter one, “Le spectre du paysage tourmenté dans Pluie et vent sur Télumée miracle”, considers the connections of the tormented landscape with the various identities of characters. These identities use flora and characteristics of some trees and plants as rhetorical constructions to highlight different perspectives of the colonial world: race and rebellion and resilience. Chapter two, “Le fromager dans le monde putrescible” in Délice et le fromager, undertakes to understand the meaning of the tree as the narrator. The identity and the nature of the possessed ceiba tree, as the narrator, reveal a corrupted colonial world. As a witness to the main character’s family and the colonial world, this tree provides a unique perspective on the destruction of the family structure and on the corruption of the colonial world. Chapter three, “La thématique du retour à travers l’espace généalogique de Pays mêlé” examines how Maryse Condé’s Pays mêlé challenges the concept of a typical family tree. The family structure through adultery and illegitimacy shows that the fragmented Surena’s genealogy appears to be constructed like a rhizome with multiple wandering links. In this chapter, we will study the questions of origin often revisited within this genealogy and we will analyze the different factors that destabilize and marginalize characters throughout several generations

Full textAbstract:
This paper argues against the charges of puerility in the films of Kevin Smith. I analyze Mallrats (1995), Clerks II (2006) and Zack and Miri Make a Porno (2008). To illustrate my contention, I offer close readings of the director's films, particularly the protagonists' bodily/linguistic performances. My efforts will vindicate my assertion that through these specialized performances, through the forceful assertion of their marginal identities, the films' protagonists encroach upon, and finally appropriate, historically dominant spaces. As a result, the spaces they appropriate acquire a new, characteristic hybridity. Michel Foucault's concept of heterotopia provides a framework for delineating the dominant and liminal spaces within Smith's cinematic/real worlds. Mikhail Bakhtin's notion of the 'carnivalesque' helps to elucidate the vagaries of the films' bodily and scriptural performances, while both Kevin Hetherington's concept of utopics and Gilles Deleuze and Felix Guattari's notion of the rhizome attempt to marry Bakhtin and Foucault. through the notion of appropriation of public space through performance to ultimately achieve a utopian, pluralistic ethos.

Full textAbstract:
Les travaux décrits dans cette thèse apportent une contribution au problème de la navigation autonome de robots mobiles dans un contexte de vision indoor. Il s’agit de chercher à concilier les avantages des différents paradigmes d’architecture de contrôle et des stratégies de navigation. Ainsi, nous proposons l’architecture RHIZOME (Robotic Hybrid Indoor-Zone Operational ModulE) : une architecture unique de contrôle robotique mettant en synergie ces différentes approches en s’appuyant sur un système neuronal. Les interactions du robot avec son environnement ainsi que les multiples connexions neuronales permettent à l’ensemble du système de s’adapter aux conditions de navigation. L’architecture RHIZOME proposée combine les avantages des approches comportementales (e.g. rapidité de réaction face à des problèmes imprévus dans un contexte d’environnement dynamique), et ceux des approches délibératives qui tirent profit d’une connaissance a priori de l’environnement. Cependant, cette connaissance est uniquement exploitée pour corroborer les informations perçues visuellement avec celles embarquées. Elle est représentée par une séquence de symboles artificiels de navigation guidant le robot vers sa destination finale. Cette séquence est présentée au robot soit sous la forme d’une liste de paramètres, soit sous la forme d’un plan. Dans ce dernier cas, le robot doit extraire lui-même la séquence de symboles à suivre grâce à une chaine de traitements d’images. Ainsi, afin de prendre la bonne décision lors de sa navigation, le robot traite l’ensemble de l’information perçue, la compare en temps réel avec l’information a priori apportée ou extraite, et réagit en conséquence. Lorsque certains symboles de navigation ne sont plus présents dans l’environnement de navigation, l’architecture RHIZOME construit de nouveaux lieux de référence à partir des panoramas extraits de ces lieux. Ainsi, le robot, lors de phases exploratoires, peut s’appuyer sur ces nouvelles informations pour atteindre sa destination finale, et surmonter des situations imprévues. Nous avons mis en place notre architecture sur le robot humanoïde NAO. Les résultats expérimentaux obtenus lors d’une navigation indoor, dans des scenarios à la fois déterministes et stochastiques, montrent la faisabilité et la robustesse de cette approche unifiéeThe work described in this dissertation is a contribution to the problem of autonomous indoor vision-based mobile robot navigation, which is still a vast ongoing research topic. It addresses it by trying to conciliate all differences found among the state-of-the-art control architecture paradigms and navigation strategies. Hence, the author proposes the RHIZOME architecture (Robotic Hybrid Indoor-Zone Operational ModulE) : a unique robotic control architecture capable of creating a synergy of different approaches by merging them into a neural system. The interactions of the robot with its environment and the multiple neural connections allow the whole system to adapt to navigation conditions. The RHIZOME architecture preserves all the advantages of behavior-based architectures such as rapid responses to unforeseen problems in dynamic environments while combining it with the a priori knowledge of the world used indeliberative architectures. However, this knowledge is used to only corroborate the dynamic visual perception information and embedded knowledge, instead of directly controlling the actions of the robot as most hybrid architectures do. The information is represented by a sequence of artificial navigation signs leading to the final destination that are expected to be found in the navigation path. Such sequence is provided to the robot either by means of a program command or by enabling it to extract itself the sequence from a floor plan. This latter implies the execution of a floor plan analysis process. Consequently, in order to take the right decision during navigation, the robot processes both set of information, compares them in real time and reacts accordingly. When navigation signs are not present in the navigation environment as expected, the RHIZOME architecture builds new reference places from landmark constellations, which are extracted from these places and learns them. Thus, during navigation, the robot can use this new information to achieve its final destination by overcoming unforeseen situations.The overall architecture has been implemented on the NAO humanoid robot. Real-time experimental results during indoor navigation under both, deterministic and stochastic scenarios show the feasibility and robustness of the proposed unified approach

Full textAbstract:
This thesis examines a youth community arts network and Caja Lúdica, one of its founder organisations, in post-conflict Guatemala, and argues that they not only temporarily create spaces of encounter and community but through their networking and exchange strategies have established a rhizomatic assemblage of practice characterised by its perseverance and its dispersed agency in different parts of the country. As such, the thesis asks the following main three questions: What are the practices of Caja Lúdica and the Community Arts Network in Guatemala; what are youth protagonists’ experiences; and what contribution can their practices make to debates on community arts in challenging environments but also in other parts of the world? By using Deleuze and Guattari’s rhizome theory it highlights notions of networking, local protagonism and collectivity asks for more sustainable practice with youth and by introducing these terms into performance and community arts scholarship, where they are scarcely explored, it makes a critical contribution to these fields. A methodological approach based on rhizomatic notions has fostered the connection of a wide range of methods such as semi-structured interviews, participant observation, ‘following’ as a research method as well as photography, the latter two of which have been developed for researching this particular networking practice in Guatemala. By using a selected set of case studies, this investigation aims to grasp the diversity and dynamics of this practice, in particular its movement and expansion across community borders through its youth protagonists. These case studies include the exploration of a local youth group and their exchange activities as well as the observation of the Network’s collective rituals and public interventions. By doing so this thesis aims to emphasise the potential of youth as creative protagonists in challenging contexts and stresses the importance to further examine their potential and ability to resist marginalisation and contribute to the reconstruction of the social fabric in war-affected communities and beyond. It further proposes that a networking and more holistic approach to practice can foster more sustainable community arts processes, not just in terms of decreasing external funding dependency and determination, but also to establish a practice culture in and between initiatives based on collectivity, exchange and support, which becomes more important in times of austerity.

Full textAbstract:
BACKGROUND:Ginger (Zingiber officinale) and turmeric (Curcuma longa) accumulate important pharmacologically active metabolites at high levels in their rhizomes. Despite their importance, relatively little is known regarding gene expression in the rhizomes of ginger and turmeric.RESULTS:In order to identify rhizome-enriched genes and genes encoding specialized metabolism enzymes and pathway regulators, we evaluated an assembled collection of expressed sequence tags (ESTs) from eight different ginger and turmeric tissues. Comparisons to publicly available sorghum rhizome ESTs revealed a total of 777 gene transcripts expressed in ginger/turmeric and sorghum rhizomes but apparently absent from other tissues. The list of rhizome-specific transcripts was enriched for genes associated with regulation of tissue growth, development, and transcription. In particular, transcripts for ethylene response factors and AUX/IAA proteins appeared to accumulate in patterns mirroring results from previous studies regarding rhizome growth responses to exogenous applications of auxin and ethylene. Thus, these genes may play important roles in defining rhizome growth and development. Additional associations were made for ginger and turmeric rhizome-enriched MADS box transcription factors, their putative rhizome-enriched homologs in sorghum, and rhizomatous QTLs in rice. Additionally, analysis of both primary and specialized metabolism genes indicates that ginger and turmeric rhizomes are primarily devoted to the utilization of leaf supplied sucrose for the production and/or storage of specialized metabolites associated with the phenylpropanoid pathway and putative type III polyketide synthase gene products. This finding reinforces earlier hypotheses predicting roles of this enzyme class in the production of curcuminoids and gingerols.CONCLUSION:A significant set of genes were found to be exclusively or preferentially expressed in the rhizome of ginger and turmeric. Specific transcription factors and other regulatory genes were found that were common to the two species and that are excellent candidates for involvement in rhizome growth, differentiation and development. Large classes of enzymes involved in specialized metabolism were also found to have apparent tissue-specific expression, suggesting that gene expression itself may play an important role in regulating metabolite production in these plants.

Full textAbstract:
Specialized metabolism (secondary metabolism) in glandular trichomes of sweet basil (Ocimum basilicum L.) and accumulation of specialized metabolites (secondary metabolites) in rhizomes of turmeric (Curcuma longa L.) was investigated using proteomic and metabolomic approaches, respectively. In an effort to further clarify the regulation of metabolism in the glandular trichomes of sweet basil, we utilized a proteomics-based approach that applied MudPIT (multidimensional protein identification technology) and GeLC-MS/MS (gel enhanced LC-MS/MS) to protein samples from isolated trichomes of four different basil lines: MC, SW, SD, and EMX-1. Phosphorylation, ubiquitination and methylation of proteins in these samples were detected using X!tandem. Significant differences in distribution of the 755 non-redundant protein entries demonstrated that the proteomes of the glandular trichomes of the four basil lines were quite distinct. Correspondence between proteomic, EST, and metabolic profiling data demonstrated that both transcriptional regulation and post-transcriptional regulation contribute to the chemical diversity. One very interesting finding was that precursors for different classes of terpenoids, including mono- and sesquiterpenoids, appear to be almost exclusively supplied by the MEP (2-C-methyl-D-erythritol 4- phosphate) pathway, but not the mevolonate pathway, in basil glandular trichomes. Our results suggest that carbon flow can be readily redirected between the phenylpropanoid and terpenoid pathways in this specific cell type. To investigate the impact of genetic, developmental and environmental factors on the accumulation of phytochemicals in rhizomes of turmeric, we performed metabolomic analysis in a 2x2x4 full factorial design experiment using GC-MS, LC-MS, and LC-PDA. Our results showed that growth stage had the largest effect on levels of the three major curcuminoids. Co-regulated metabolite modules were detected, which provided valuable information for identification of phytochemicals and investigation of their biosynthesis. Based on LC-MS/MS data, 4 new diarylheptanoids were tentatively identified in turmeric rhizomes using Tandem-MSASC, a home-made software tool that automatically recognizes spectra of unknown compounds using three approaches. Based on our metabolomic results, we proposed two new strategies, “metabolomics-guided discovery” and “correlation bioassay”, to identify bioactive constituents from plant extracts based on information provided by metabolomic investigation.

Full textAbstract:
Thalassia testudinum Banks and Solander ex König is the dominant seagrass in the Gulf of Mexico, Caribbean and the West Coast of Florida, yet little rhizome elongation, new short shoot production, or new rhizome meristem production data has been collected via direct measurement. A study of the rhizome growth of T. testudinum was completed in December 2004 in southern Tampa Bay that determined growth after 26.5 months. Two PVC planting frames each containing four rhizomes with 2 short shoots, two rhizomes with 4 short shoots, and two rhizomes with 8 short shoots were planted next to existing T. testudinum beds at 5 sites (n = 10 planting frames). The rhizome apical meristem was removed from half of each set of short shoot units on each planting frame. Plants initially lacking a rhizome meristem produced more new long shoot meristems than those planted with an intact meristem, and larger planting units produced more new rhizome meristems than smaller ones, P = 0.001 and P < 0.001, respectively.
The total number of rhizome meristems per planting unit (new meristems + initial meristem) was greater in plantings initially lacking a long shoot meristem in the 2, 4 and 8 short shoot size classes. Only the two short shoot plants benefited from an intact rhizome meristem at planting time, elongating 66.4 cm versus 60.4 cm for plants initially lacking a rhizome meristem at 26.5 months. In the 4 and 8 short shoot classes, plants that
lacked a rhizome meristem at planting outpaced those with a meristem, producing 192.1 and 277.9 for 4 and 8 short shoot plants compared to 120.9 cm and 177.7 cm for plants with a meristem during the same time period. The greatest growth rate increases were due to lateral branching on planting units that lacked a rhizome meristem in the two largest size classes (4 and 8 short shoots); the differences between plants with an intact rhizome meristem and those without with the size classes pooled did not prove to be statistically different, P = 0.112. Differences among the size classes were significant, however, P < 0.001. Analysis of new short shoots was analogous to the results for rhizome elongation, with the presence of an initial rhizome factor proving insignificant, P = 0.401, and the initial number of short shoots factor proving significant, P < 0.001.
The rhizome growth, new short shoot production, and new rhizome meristem production data determined by direct measurements in this study appear to be the first planting unit measurements for this species under natural conditions.

Canna edulis, une plante amylacée pluriannuelle, de la famille Cannaceae, originaire d'Amérique du Sud, accumule de l'amidon dans son rhizome. L'objectif des travaux de thèse est d'étudier la culture du Canna à La Réunion en fonction des conditions pédoclimatiques et des saisons avec caractérisation de la qualité des rhizomes selon ses stades de développements. Sept parcelles expérimentales sont suivies sur deux sites contrastés : la Plaine des Palmistes et Bassin Plat. Tout au long de la croissance des plants, des données sont enregistrées sur la qualité des sols, la pluviométrie, les températures moyennes, et le rayonnement pour caractériser les sites. Des indicateurs de stades de développements sont suivis pour informer de l'état de maturité des plants et évaluer l'effet des conditions pédoclimatiques sur leur développement. Des échantillonnages réguliers sont réalisés pour caractériser le développement et la composition des rhizomes mais également les propriétés technologiques et intérêts nutritionnels en fonction de leurs maturités. C'est ainsi que des dosages d’amidons, de sucres libres, en lien avec la viscosité et la gélatinisation, de même que les teneurs en composés phénoliques et leur activité antioxydantes, ont été évalués sur plusieurs types de produits intermédiaires : rhizomes lyophilisés, amidons ou fibres alimentaires. Outre son caractère innovant dans le domaine des procédés d'extraction d’amidon à forte valeur ajoutée, la particularité de ce travail de thèse réside dans le fait qu'il s'inscrit dans le cadre plus vaste de mise en place de la filière Canna et de sa valorisation agronomique, technologique et nutritionnelleCanna edulis, is a multiannual plant, from the Cannaceae family, originating from South America, that accumulate starch in its rhizome. This thesis work aims to study Canna’s culture on Réunion Island depending on soil, climate and season specificities using rhizome quality changes depending on the plants development stages. Seven experimental crops were followed at two contrasted sites: La Plaine des Palmistes and Bassin Plat. During plant growth, soil quality, rain, mean temperatures and solar radiation data were collected in order to characterize the planting locations. Development stage indicators were monitored to enlighten plants maturity status and evaluate soil and climate effects on their development. Regular samplings were scheduled to characterize the rhizomes development and composition but also their technological properties and nutritional interests as influenced by their maturity. Thus, starch, free sugars, viscosity, gel formation properties as well as phenolics contents and their antioxidant activities were evaluated on several intermediate products namely freeze-dried rhizomes, starches and dietary fibers. Besides its innovative nature on the high-valued starch extraction process field, this thesis particularity relies on the fact that it is integrated in the wide project of Canna culture settlement and its agronomic, technologic and nutritional enhancement

A pesquisa intitulada Motivação Criadora e Recepção Estética no Espetáculo Re-Sintos da Muovere Companhia de Dança tem a seguinte indagação: Como operam as motivações criadoras e o processo de recepção de um espetáculo de dança contemporânea? O espetáculo escolhido para investigar o processo de criação e recepção traz o cruzamento das fronteiras entre a dança e o teatro, seja pela composição do elenco de bailarinos e atores, seja pela direção geral e cênica ter sido realizada, respectivamente, por Jussara Miranda e Jezebel de Carli, uma artista da dança e outra do teatro. Re-Sintos apresenta como características: a ênfase da não neutralidade facial; a utilização de elementos sonoros, ora produzidos pelos bailarinos, ora acompanhados pela trilha musical; a utilização de cenário, o uso de narrativa fragmentada; a utilização de diálogo com questões do cotidiano; por fim, valoriza a plasticidade do movimento corporal como principal fio condutor. Como modo de sistematizar e organizar a leitura, esta pesquisa é dividida em três capítulos: O capítulo I analisa como acontece a articulação entre a dança e o teatro no espetáculo Re-Sintos. O capítulo II verifica o que envolve o processo de recepção e como o espetáculo se oferece ao exercício receptivo. O capítulo III examina e apresenta o modo como opera a produção e a recepção do espetáculo Re-Sintos a partir de algumas características aproximativas do rizoma de Gilles Deleuze e Félix Guatarri. As características presentes no Re-Sintos retratam um modo de condução do trabalho, no qual se evidencia a presença de um caráter investigativo que tem como efeito a multiplicidade. Essa multiplicidade compreende as conexões, as rupturas e as contaminações consentidas pelo olhar questionador dos produtores num processo dinâmico de territorialização, desterritorialização e reterritorialização da criação. Quanto à recepção estética, observa-se que cada espectador articula os conhecimentos prévios, os sentidos plurais e paradoxais em linhas de segmentaridade e linhas de desterritorialização. Como a percepção produz constantemente conexões e desdobramentos, ao criar novos nexos e exigir sem cessar outros agenciamentos, os vínculos entre as motivações criadoras e a recepção estética são rizomáticos e não permitem ao espectador a identificação completa das fontes ou origens.The research entitled Creative Motivation and the Aesthetic Reception at Re- Sintos Performance of Muovere Dance Company has a question: How creative motivations and receptive process operate in a contemporary dance performance? The performance chosen to investigate the process of creation and reception crosses the borders between dance and theater, either by the casting composition by dancers and actors or by the general and scenic direction done, respectively, by Jussara Miranda and Jezebel de Carli, a dance artist and a theater artist. Re-Sintos has as characteristics: the emphasis of the non-facial neutrality; the utilization of sound elements, be it produced by the dancers or accompanied by the musical track; the scenery presentation; the use of the fragmented narrative; the utilization of dialogue with daily subjects; at least, values the corporal movement plasticity as its principal thread. As a way to systematize and organize the reading, this research is divided in three chapters: Chapter I analyses how the articulation between dance and theater happens at the Re-Sintos performance. Chapter II verifies what involves the reception process and how the performance offers itself to the receptive exercise. Chapter III examines and presents the way how the production and the reception of the Re-Sintos performance operate from some approximate characteristics from Gilles Deleuze and Félix Guattarri's rhizome. The features presented in Re-Sintos portray a conduction way of the work, which shows the presence of an investigative character that has the multiplicity as its effect. This multiplicity comprehends the connections, ruptures and contaminations consentied by the questioning way of look of the producers in a dynamic process of the creation's territorialization, deterritorialization and reterritorialization. About the aesthetic reception, it is observed that each spectator articulates its prior knowledge, the plural and paradoxical feelings in lines of segmentarity and lines of deterritoriamization. As the perception produces constantly connections and consecutive developments, when it creates new connections and demand without ceasing other agency the links between the creative motivations and the aesthetic receptions are rhizomatous and do not allow the spectator the full identification of the sources or origins.

Full textAbstract:
Arundinaria gigantea (Walt.) Muhl. (giant cane) is a native North American bamboo. The mass assemblages of giant cane stems (culms) can form monotypic stands called "canebrakes" with historic distribution encompassing floodplains of the southeastern United States. Canebrake ecosystems have served as an important habitat for a variety of mammalian, avian, and reptilian species due in part by the protective nature the dense culms provide. Also, giant cane also can serve as an effective riparian zone buffer for the protection of water quality. Land conversion and altered disturbance regimes have reduced cane to 2% of historical accounts. Consistently, there is great interest in restoring canebrake ecosystems. However, canebrake restoration efforts face difficulties such as infrequent seeding and low viability, limited availability of seedlings or rhizome planting stock, and inefficient establishment and management techniques. To address these problems, two studies were designed to further develop giant cane propagation thereby aiding management efforts intended in restoring canebrake ecosystems. Study 1 (greenhouse) objective was to compare the survivability and growth responses of bare rhizomes and rhizomes with attached and trimmed culms with different planting orientation. Study design was a randomized complete block with approximately 20 rhizomes of each propagule type (bare rhizomes, rhizomes with culms trimmed to 3cm and rhizomes with culms trimmed to 20cm) planted in two orientations (buried flat or angled and partially exposed) in each of 4 benches (N=239). Propagule type and planting orientation were determined randomly. After six months, propagule survival was 86% and was independent of orientation (chi square 1df = 1.56, p=0.212) and propagule type (chi square 2df =3.88, p=3.88). There was an interaction between planting orientation and propagule type for the number of new rhizomes and culms, above ground biomass, but not for newly formed rhizome diameter or cumulative culm and rhizome length. Rhizome propagules with attached trimmed culms produced, on average, one more rhizome and were 71 cm longer than newly formed rhizomes from the bare rhizome propagules. Planting orientation had no effect on any measured character of long culmed propagules, burying the short-culmed or bare rhizomes tended to reduce growth responses. However, among exposed propagules, growth responses tended to be similar. Study 2 (field-scale) objective was to determine if genotype (3 collection sources) and collection season/ planting season (C/P) (fall/fall, fall/spring, spring/spring) affect survival and growth of giant cane. Study design was a randomized complete block design with between 12 and 20 bare rhizomes per each of 3 collection sources (subplots) planted in each of 3 rows (collection season/ planting season main plots) blocked 6 times across 2 sites (N=2086). Location of collection sources within subplots and C/P within plots were randomly chosen. Rhizomes were planted in rows using a tree planter. Mean survival of cane plants after one growing season was similar at each site with a mean of 11.1%. Survival was dependent on collection source and C/P seasons. Survival ranged from a high of 38.3% for the spring/spring planted Upper Cache River source to 0.4% for two of the other 9 treatment combinations. Collecting and planting rhizomes in the spring for two of the three collection sources produced the highest percent survival compared to stock collected in the fall then planted or stored until spring. These results suggest the importance of collection source, collection season, planting season, propagule morphology and orientation on the survival and new growth of giant cane in southern Illinois.

Full textAbstract:
The Dominican American writer, Julia Alvarez, often portrays in her works immigrant subjects that experience biculturalism. In Return to Sender, Alvarez problematizes the issue that involves Mexican immigration in the United States. This dissertation investigates the emergence of a new Mexican immigrant subjectivityfrom this cultural encounter. With the advance of technologies, the contemporary world seems a space without boundaries and limits. Individuals connect with a multiplicity of places and cultures, establishing bonds, fostering business, and raising families. In other words, they promote what Gloria Anzaldúa calls cross-pollination (Borderlands 99), creating roots everywhere. This immigrant that establishes connections and has roots everywhere is recognized and represented in literary realm as a rhizomatic immigrant. This term is originated from biology and refers to species of underground stems commonly mistaken to roots due to the fact that both have similar function. Biology also presents another particular species of rhizomes that occurs above the ground known as stolons from which I borrow the term to name this contemporary immigrant subject that comes out from the darkness of anonymity and confinement, seeking for oxygenation, ventilated spaces, fluidity, and visibility. Under the light of this analogy, this work dialogues with biology in order to analyze the emergence and behavior of the Stolon immigrant in Julia Alvarezs narrative, as well as to investigate whether the representation of the characters writing in form of letters and diary, is an extension of her own Stolon subjectivity.A escritora dominicana-americana, Julia Alvarez, frequentemente retrata em suas obras sujeitos imigrantes que vivenciam biculturalismo. Em Returnto to Sender, Alvarez problematiza o tópico que envolve a imigração mexicana nos Estados Unidos. Essa dissertação investiga o surgimento de uma nova subjetividade imigrante mexicana a partir desse encontro cultural. Com o avanço das tecnologias, o mundo contemporâneo parece um espaço sem fronteiras e limites. Indivíduos se conectam com uma multiplicidade de lugares e culturas, estabelecem vínculos, fomentam negócios, e criam famílias. Em outras palavras, eles promovem o que Gloria Anzaldúa chama de polinização cruzada (Borderlands 99) criando, assim, raízes em todo lugar. Esse imigrante que estabelece conexões e tem raízes em todo lugar é reconhecido e representado do campo literário como imigrante rizomático. Este termo é originário da biologia e se refere a espécies de caules subterrâneos comumente confundidos com raízes devido ao fato de ambos terem funções semelhantes. A biologia também apresenta outra espécie particular de rizomas que ocorrem sobre o solo conhecidos como Estolhos de quem tomo o termo por empréstimo para nomear esse sujeito imigrante contemporâneo que sai da escuridão do anonimato e confinamento buscandooxigenação, espaço ventilado, fluidez e visibilidade. Sob a luz dessa analogia, este trabalho dialoga com a biologia de forma a analisar o surgimento e o comportamento do imigrante Estolho na narrativa de Julia Alvarez, assim como a investigar se a representação da escrita da personagem em forma de cartas e diário é uma extensão da sua própria subjetividade Estolho.

Detta strävar vi efter genom att tillämpa ett rhizomatiskt perspektiv i vår designprocess samt försök till att närma oss en icke-linjär designmetodik. Det rhizomatiska perspektivet används som en källa för inspiration, en väg till att finna nya lösningar och verktyg till berättandet. Vårt prövande av ljuddesignen gjordes i en filmproduktion där vi som ljuddesigners gjorde försök till att väva in ljuddesign under hela projektets gång och arbeta proaktivt för att skapa utrymme för vår design.With this bachelor thesis we seek to expand the understanding and interest of the narrative potential in sound design. We aim to do this by applying a rhizomatic perspective to our design process and attempt to approach a non-linear design method. The rhizomatic perspective is used as a source of inspiration, a way of finding new narrative tools and solutions. The testing of sound design was made in a film production where we, as sound designers, made attempts to weave sound design into the whole course of the project and work proactively to create space for our design.

Full textAbstract:
This study examined the effect of density on rhizome bud production in quackgrass (Elytrigia repens (L.) Nevski). The treatments consisted of two biotypes (L8 and L9), and nine density levels ranging from 1 to 22 plants m$ sp{-2}$. The results showed that bud production per plant diminished with increasing density in both biotypes. However, biotype L8 was less productive at low densities, but almost equal to L9 at higher densities. A second experiment was undertaken to measure the expansion of clonal colonies and the distribution of shoots within these colonies. For both biotypes the growth rate was highest in late summer and early fall, but colonies of L9 grew more rapidly. Biotype L9 had 59% of its total biomass located within 40 cm of the centre as compared with 81% in L8. Overall, Biotype L9 produced more rhizome buds, responded more strongly to intraspecific interference, and grew more rapidly as a colony.

Full textAbstract:
Peu d’études ont porté sur le rhizome du bleuet nain et les effets des pratiques culturales sur ce dernier sont inconnus. Trois expériences ont été réalisées. La première visait à vérifier l’influence d’une fertilisation sur le rhizome et son développement en fonction de l’âge de la bleuetière et de l’étape du cycle de culture (végétation ou récolte) à quatre moments au cours de la saison. Les deux autres ont permis d’examiner l’impact du sectionnement des rhizomes et d’une taille effectuée à différentes hauteurs en bleuetières récemment aménagées. La fertilisation a favorisé le développement de nouveaux rhizomes et la formation d’un plus grand nombre de bourgeons, mais n’a pas influencé leurs teneurs en sucres. Le sectionnement a activé un grand nombre de bourgeons et le potentiel de régénération des segments est lié à leur diamètre et leur longueur. Une taille à moins de 1 cm du sol a stimulé davantage la formation de tiges à partir du rhizome.There have been very few studies on the rhizome of the lowbush blueberry, and as such, the effects of cultural practices on that specific rhizome are unknown. Three experiments have been conducted. The first one dealt with the effects of fertilization on the rhizome and its development depending on the age of the blueberry field and the cultural cycle phase (vegetation or harvest) at four different times during the season. The second and the third experiments dealt with the impact of rhizome severing and stem pruning at different heights in newly planned blueberry fields and their density. Fertilization fostered the development of new rhizomes with a higher number of buds, but did not change their sugar content. The severing stimulated a lot of buds, and it was noticed that the segments’ regeneration potential was linked to their diameter and length. Pruning at less than 1 cm from the ground boosted stemming from the rhizome.

Full textAbstract:
High-stakes testing has grown in scope and impact in recent years, as accountability decisions regarding funding, school sanctions, and teacher evaluations often depend on standardized test results. The shift toward more stringent and punitive testing mandates has not gone unchallenged however, as pockets of resistance have emerged among teachers, parents, and scholars, and a growing "opt-out" movement has picked up steam nationwide. Teachers in particular have played a critical role in resistance to high-stakes testing, even while adhering to these same policies in their professional roles. This study examines resistance to standardized testing via the 'opt-out' movement organizing process. I specifically look at teachers' participation in organizing and resistance, and how positions as teachers and sometimes parents influence their participation. I frame the project with a post-structuralism lens, utilizing the Deleuzoguattarian concept of the rhizome to illustrate the complex and connected nature of teachers' involvement in this social movement.

Full textAbstract:
This thesis exemplifies, through the exploration of a specific case study, how the design of an online professional development resource is capable of penetrating, disrupting, and fostering innovation in online teaching practices within a wide range of existing professional education networks. Following its release in 2009, the ‘Learning to Teach Online’ (LTTO) project spread rapidly around the world via conduits such as Twitter, Facebook, blogs, institutional links and word of mouth — throughout K-12, vocational, higher education and private consultancies across 146 countries and territories. This thesis investigates how the design of LTTO facilitated its discovery, dissemination and integration in a range of educational contexts. There was a large volume of data collected from Web 2.0 activity surrounding LTTO. Using data visualisation techniques, patterns and hidden relationships between individuals sharing and using the resources were revealed, that provided insight into previously invisible relationships between individuals within vastly different established professional networks all over the world. The concept of the rhizome is at the core of this thesis, inspired by the observation of the growing patterns of connection between seemingly disparate educational communities globally, in a manner that was neither precisely controlled nor predictable. Key outcomes include a detailed analysis of the design of an online professional development resource that was effective across a range of disciplines and education sectors; the determination of an effective method of researching the spread and use of similar initiatives; and observations and strategies that can help others to improve the design process for future online professional development resources.

There are a number of papers in the journal that reflect a trend in environmental education towards deliberating recuperative, relational epistemologies. In their paper addressing the near-schism between those that appear to be antagonistic to post-structuralism and deconstruction, and those that find them generative in their inquiries, Noel Gough and Leigh Price go right to the heart of human inquiry by questioning the most commonly held assumption in the research enterprise – that the social sciences require a different methodology from the natural sciences.Through giving attention to relativist (constructionist) epistemology and a stratified, realist ontology – which assumes a relational account of ontology – they suggest the same basic methodology for both the social and natural sciences, arguing that ‘... society and humans mutually transform/reproduce each other, just as nature and humans mutually transform/reproduce each other’. In doing this, they address over-simplified dialectics between ‘constructionism’ and realism which has shaped much human inquiry (including environmental education research).

A total of 37 strains of soft-rot Erwinia were isolated from the diseased plant tissues collected from colored calla lily grown fields. Based on the physiological and biochemical tests, they were all identified as Erwinia carotovora subsp. carotovora. The incidence of rhizome rot of colored calla lily caused by E. corotovora subsp. carotovora was greater in the rhizomes artificially wounded than those not artificially wounded. The soft rot incidenceof colored calla lily cultivar Best Gold inoculated with E. carotovora subsp. carotovora through the wounds just after flowers being plucked was 100 %, while the incidence of rotting decreased to 16.7 % when the inoculation was made 36 hours later. Rhizomes of colored calla lily obtained from various sources were detected for the soft-rot Erwinia, the results showed that 23.3 % ~ 84 % of rhizomes were contaminated with soft-rot Erwinia. The number of soft-rot Erwinia on rhizomes of colored calla lily after storage was detected on modofiedCVP selective medium. The results showed that soft-rot Erwinia on rhizomes with cured rotted lesions could reach to 104 ~ 106 cfu/g dry periderm. In green housetest, the soft rot incidence of colored calla lily grown from rhizomes with cured rotted lesions, rhizomes which rotted lesions were excised and symptomlessrhizomes was 86.7 %, 33.3 % and 6.7 %, respectively. Sensitivity of the 37 strains of E. carotovora subsp. carotovora. to commercial formulated agroche- micals was tested on nutrient agar plates. It was found that all the Erwinia carotovora subsp. carotovora strains tested were sensitive to basic copper sulfate + cufram Z (500X), copper oxychloride + manzeb + zinzeb (500X), cuprous oxide (500X), kasugamycin + copper oxychloride (1000X), oxine-copper + copper hydroxide (500X) and tribasic copper sulfate (500X). And with the exception of 1 ~ 3 strains, most strains tested were also sensitive to streptomycin + tetracycline (1000X), streptomycin sulfate (100 and 200 ppm) and thiophanate-methyl + streptomycin (1000X), while all the strains tested were resistant to mancozeb (400X), nonyphenol copper sulfonate (500X) and tecloftalam (1000X). Treatment of rhizomes with agrochemicals was able to reduce the population of E. carotovora subsp. carotovora on the rhzomes artificially infested. Chemical treatment of rhizomes at 45℃ were much better than that at 26℃ to reduce the population of E. carotovora subsp. carotovora onthe rhizomes. However, the effectiveness of chemical treatment varied among the rhizomes treated. Copper oxychloride + manzeb + zinzeb (500X) appeared to be the most effective among 11 agrochemicals tested to reduce the population of E. carotovora subsp. carotovora on the infested rhizomes. When the infested concentration of E. carotovora subsp. carotovora was at 108 cfu/ml, the number of E. carotovora subsp. carotovora on the infested rhizomes after treated with copper oxychloride + manzeb + zinzeb (500X) at 45℃ for 40 minutes could reduce to an undetected level. When the infested concentration of E. carotovora subsp. carotovora was at 106 cfu/ ml, the number of E. carotovora subsp. carotovora on most of the infested rhizomes after treated with both copper oxychloride + manzeb + zinzeb (500X) and thiophanate-methyl + streptomycin (1000X) could also reduce to an undetected level. In addition, soft rot incidence of both copper oxychloride + manzeb + zinzeb (500X) and thiophanate-methyl + streptomycin (1000X) treated rhizomes was much lower than that of untreated rhizomes. Among 11 commercial growing media examined, no soft-rot Erwinia was detected after enrichment in these media. Survival of E. carotovora subsp. carotovora in these growing media was studied, it was found that E. carotovora subsp. carotovora could survive much better in these media at low temperature (12℃) than at high temperature (30℃). E. carotovora subsp. carotovora was able to survive for over 180 days in vermiculite, perlite, Hydrocorn, TKS-1 Instant, volcano rock and sphagnum moss at 12℃, whereas they could only survive less than 50 days at 30℃. High humidity (RH 100 %) was favorable for E. carotovora subsp. carotovora to survive on the leaves of colored calla lily. In addition, application of 1 % of calcium nitrate solution to colored calla lily during the growing season could increase the calcium content of various parts of plants.
