The B-L/Electroweak Hierarchy in Smooth Heterotic Compactifications

Subjects: subject: High Energy Physics - Theory (hep-th)

description: E8 X E8 heterotic string and M-theory, when appropriately compactified, can give rise to realistic, N=1 supersymmetric particle physics. In particular, the exact matter spectrum of the MSSM, including three right-handed neutrino supermultiplets, one per family, and one pair of Higgs-Higgs conjugate superfields is obtained by compactifying on Calabi-Yau manifolds admitting specific SU(4) vector bundles. These "heterotic standard models" have the SU(3)_{C} X SU(2)_{L} X U(1)_{Y} gauge group of the standard model augmented by an additional gauged U(1)_{B-L}. Their minimal content requires that the B-L gauge symmetry be spontaneously broken by a vacuum expectation value of at least one right-handed sneutrino. In a previous paper, we presented the results of a renormalization group analysis showing that B-L gauge symmetry is indeed radiatively broken with a B-L/electroweak hierarchy of O(10) to O(10^{2}). In this paper, we present the details of that analysis, extending the results to include higher order terms in tan[beta]^{-1} and the explicit spectrum of all squarks and sleptons.

Holiday homes in Tasmania
Creators: name: Thorne, K
Publisher: name: University Of Tasmania
Year: 2023

description: Large scale ownership and use of holiday homes is a recent phenomenon in most developed countries. Increased leisure time, affluence and mobility since World War II have enabled many sections of society to own a holiday home. Holiday homes permit a regular change of environment and participation in a wide range of recreational activities. Rural economies often benefit from holiday home occurrence through increased trade for local business, opportunities for farmers to sell surplus land and produce, and increased taxation revenue for local authorities. Due to the large amounts of land they require, holiday homes have become a distinctive element in the settlement pattern in coastal and lacustrine environments of Tasmania. High density ribbon settlement in some areas has led to both physical and visual erosion of these landscapes. The distribution of holiday homes in Tasmania in 1977 and the changes in the distribution since 1960 are examined, The current location of holiday homes and changes in the distribution pattern of holiday homes are shown to be dependent upon the location of attractive sites, access from major population centres and the socio-economic characteristics of the population. These factors combine to produce some distinctive spatial regularities both in the distribution of holiday homes and in the relationship between the permanent homesite. The curnmt state of planning legislation in Tasmania in relation to holiday homes is discussed.

The influence of weak texture on the critical currents in polycrystalline MgB$_2$
Creators: name: Eisterer, M.
name: Weber, H. W.
Publisher: name: arXiv
Year: 2010
Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: The current transport in polycrystalline MgB$_2$ is strongly influenced by the intrinsic anisotropy of this superconductor. Untextured bulks and wires are macroscopically isotropic, but the grains retain their anisotropic properties and the field dependence of the critical currents is much stronger than in isotropic superconductors. Weakly or partially textured tapes are macroscopically anisotropic, but the anisotropy of the zero resistivity (or irreversibility) field is smaller than the intrinsic upper critical field anisotropy, $γ$. The \Jc-anisotropy is field and temperature dependent and can be much larger than $γ$. The most suitable parameter for the quantification of the macroscopic anisotropy is, therefore, the anisotropy of the zero resistivity field. It is difficult to distinguish between a higher degree of texture at a lower intrinsic anisotropy and a weaker texture at higher anisotropy and hardly possible based on the field dependence of the critical current anisotropy alone. The knowledge of the upper critical field is crucial and angular resolved measurements of either the critical currents or, better, the resistive in-field transitions are favorable for this purpose.

description: This paper presents an analysis that searched for systematic effects within the CoRoT exoplanet field light curves. The analysis identified a systematic effect that modified the zero point of most CoRoT exposures as a function of stellar magnitude. We could find this effect only after preparing a set of learning light curves that were relatively free of stellar and instrumental noise. Correcting for this effect, rejecting outliers that appear in almost every exposure, and applying SysRem, reduced the stellar RMS by about 20 %, without attenuating transit signals.

description: REACH policy brief: The Government of Bangladesh has provided global leadership in progress to improved drinking water access, with an estimated coverage of 98.5% of its 160 million citizens in 2019. However, the coverage decreases to 42.5% when service delivery accounts for indicators of water quality, proximity and sufficiency (UNICEF/MICS, 2019). As the Government sets out to revise the 1998 National Policy for Safe Water Supply and Sanitation, the ‘SafePani’ model proposes reforms in institutional design, sustainable finance, and information systems, to advance the Sustainable Development Goal (SDG) Target 6.1 of universal access to safe and affordable drinking water for households, schools and healthcare facilities.

description: We consider an ultracold rotating Bose gas in a harmonic trap close to the critical angular velocity so that the system can be considered to be confined to the lowest Landau level. With this assumption we prove that the Gross-Pitaevskii energy functional accurately describes the ground state energy of the corresponding $N$-body Hamiltonian with contact interaction provided the total angular momentum $L$ is much less than $N^2$. While the Gross-Pitaevskii energy is always an obvious variational upper bound to the ground state energy, a more refined analysis is needed to establish it as an exact lower bound. We also discuss the question of Bose-Einstein condensation in the parameter range considered. Coherent states together with inequalities in spaces of analytic functions are the main technical tools.

description: Densities in compact stars may be such that quarks are no longer confined in hadrons, but instead behave as weakly interacting particles. In this regime perturbative calculations are possible. Yet, due to high pressures and an attractive channel in the strong force, condensation of quarks in a superfluid state is likely. This can have interesting consequences for magnetic fields, especially in relation to the discovery of slow-period free precession in a compact star. In this proceedings there will be a discussion of the mass-radius relations of compact stars made from quark matter and magnetic field behaviour in compact stars with a quark matter core.

Conservation: A study in the growth of public interest. (With special reference to bushwalkers and their clubs).
Creators: name: Shackel, PJ
Publisher: name: University Of Tasmania
Year: 2023

description: If one has to choose an arbitrary point in any historical study, the founding of the Tasmanian Conservation trust in April 1968 marked a point in the development of Tasmanian interest in conservation. However, this study aims to examine not the actual founding of the Trust, but rather the efforts and arguments of the conservation enthusiast, especially the bushwalker,whihc cleared the way for the founding of the trust. Therefore it is concerned with the problem of what drove men towards a realisation of the need for conservation, and in what way they argued in an attempt to modify and predominantly anti-conservaton social environment.

description: We introduce Locally Linear Embedding (LLE) to the astronomical community as a new classification technique, using SDSS spectra as an example data set. LLE is a nonlinear dimensionality reduction technique which has been studied in the context of computer perception. We compare the performance of LLE to well-known spectral classification techniques, e.g. principal component analysis and line-ratio diagnostics. We find that LLE combines the strengths of both methods in a single, coherent technique, and leads to improved classification of emission-line spectra at a relatively small computational cost. We also present a data subsampling technique that preserves local information content, and proves effective for creating small, efficient training samples from a large, high-dimensional data sets. Software used in this LLE-based classification is made available.

description: We investigate the vortex excitations induced by a spin-polarized current in a magnetic nanopillar by means of micromagnetic simulations and analytical calculations. Damped motion, stationary vortex rotation and the switching of the vortex core are successively observed for increasing values of the current. We demonstrate that even for small amplitude of the vortex motion, the analytical description based the classical Thiele approach can yield quantitatively and qualitatively unsound results. We suggest and validate a new analytical technique based on the calculation of the energy dissipation.

description: A strong inhomogeneous static electric field is used to spatially disperse a supersonic beam of polar molecules, according to their quantum state. We show that the molecules residing in the lowest-lying rotational states can be selected and used as targets for further experiments. As an illustration, we demonstrate an unprecedented degree of laser-induced 1D alignment $(=0.97)$ and strong orientation of state-selected iodobenzene molecules. This method should enable experiments on pure samples of polar molecules in their rotational ground state, offering new opportunities in molecular science.

description: The Search for Extraterrestrial Intelligence (SETI) has thus far failed to provide a convincing detection of intelligent life. In the wake of this null signal, many "contact pessimistic" hypotheses have been formulated, the most famous of which is the Rare Earth Hypothesis. It postulates that although terrestrial planets may be common, the exact environmental conditions that Earth enjoys are rare, perhaps unique. As a result, simple microbial life may be common, but complex metazoans (and hence intelligence) will be rare. This paper uses Monte Carlo Realisation Techniques to investigate the Rare Earth Hypothesis, in particular the environmental criteria considered imperative to the existence of intelligence on Earth. By comparing with a less restrictive, more optimistic hypothesis, the data indicates that if the Rare Earth hypothesis is correct, intelligent civilisation will indeed be relatively rare. Studying the separations of pairs of civilisations shows that most intelligent civilisation pairs (ICPs) are unconnected: that is, they will not be able to exchange signals at lightspeed in the limited time that both are extant. However, the few ICPs that are connected are strongly connected, being able to participate in numerous exchanges of signals. This may provide encouragement for SETI researchers: although the Rare Earth Hypothesis is in general a contact-pessimistic hypothesis, it may be a "soft" or "exclusive" hypothesis, i.e. it may contain facets that are latently contact-optimistic.

description: Deliverable 5.1 “Business case Implementation Guidelines” is the first deliverable of WP5 led by EV ILVO. The objective of this deliverable is to provide a common framework for project partners involved in business cases to ensure the smooth progress of the WP5 and establish efficient communication between the different project partners and the lighthouse customers.
 • In the first section, the general objectives, tasks and deliverables of the WP5 listed, and all Business cases (BC) are summarised and presented in an informative manner to help BC actors follow the vision of the Envision project declared in the grant agreement.
 • The second section, which is the actual contribution of this deliverable, declares the actor roles, the scheduled activities within the WP and the mapping of those activities to each role. This way, we describe clearly: which role is doing what.
 • The third section goes one step further: It assigns per business case the actors to the roles. This way, we describe clearly per business case: which actor needs to do what and with whom.

The astrophysics that can be done when the LISA data becomes available is presented, with particular attention to verification binaries, the overall Galactic populations, neutron star and black hole binaries and sources in globular clusters. I discuss the synergy with electro-magnetic observations and correct an error in the estimate of the number of LISA systems that can be found in the optical compared to Nelemans (2006a) and conclude that at least several hundreds of systems should be detectable.

description: In its short-bunch operation mode, the KIT storage ring KARA provides picosecond-long electron bunches, which emit coherent synchrotron radiation (CSR) up to the terahertz frequency range. Due to the high spatial compression under these conditions, the self-interaction of the bunch with its own emitted CSR induces a wake-field, which significantly influences the longitudinal charge distribution. Above a given threshold current, this leads to the formation of dynamically evolving micro-structures within the bunch and is thus called micro-bunching instability. As CSR is emitted at wavelengths corresponding to the spatial dimension of the emitter, these small structures lead to an increased emission of CSR at higher frequencies. The instability is therefore deliberately induced at KARA to provide intense THz radiation to dedicated experiments. To further increase the emitted power in the desired frequency range, we consider the potential of RF amplitude modulations to intentionally excite this form of micro-bunching in short electron bunches.
Structural unity in tennyson's idylls of the king
Creators: name: Harrs, Reynold August
Publisher: name: University of British Columbia
Year: 2011

description: This thesis, which is a close textual analysis of Tennyson's The Idylls of the King, attempts to explicate the poem in terms of Arthur's Vow. The Vow is seen as the thematic and structural centre of the poem. Accordingly, the thesis falls into two sections. The first is concerned with a discussion of the themes found in the Idylls and how they relate to the Vow; the second is concerned with the structural unity of the poem in terms of its imagery, mood and motifs. The thesis attempts to explain why in a world characterized by the eternal conflict between good and evil, between man and nature, it is necessary for the knights to obey Arthur's Vow. The knights and ladies are then discussed, in particular their failure to obey the Vow, and the consequences of their failure. Since the adultery between Lancelot and Guinevere is at the heart of the dissolution of the Round Table, and is never described explicitly, an attempt is made to interpret their relationship in terms of disobedience to the Vow. The thesis also examines the ways in which Tennyson gives unity to what appears to be a collection of independent poems. Unity, in particular in mood, is supplied by the poet's moralistic voice as well as by the use of lyrics. Imagistic and verbal motifs are traced through, the poem, and are shown to have a cumulative effect corresponding to the narrative climax. Finally, the use of nature imagery is shown to emphasize the struggle between man and nature as well as to sharpen the contrast between the civilization of Camelot and the ever-constant threat of anarchic nature, which threatens to erupt once the knights fail to obey the Vow.
Conceptual, theoretical and ethical problems in the vertical mosaic
Creators: name: Heap II, James Louis
Publisher: name: University of British Columbia
Year: 2011

description: The Vertical Mosaic is re-examined and an 'internal' critique of its multiple conceptual, theoretical and ethical problems is provided. Porter's value position in a 1961 essay is outlined and set up as a 'bench-mark' for evaluating the consistency of his 1965 value position. Value inconsistency is discovered in the form of a 'strategy of respectability,' consisting of five 'tactics.' This strategy is then drawn upon throughout the essay to explicate some of Porter's conceptual and theoretical errors. These errors involve his treatment of class, power and democracy. It is argued that Porter's important distinction between "real middle class" and "middle majority" violates his original position on class, and is inadequate for his stated purpose. Furthermore, the theoretical foundations underlying the structure of class are unexplicated. His failure to distinguish between power and authority raises logical and utilitarian problems. Thus the theoretical foundations underlying the structure of power are inadequate. In both the case of class and power he 'transcends' his original definition in the process of doing his analysis. The normative context of his study is found to be ambiguous, but appears to be the theory of democratic elitism. This constitutes a major value inconsistency because this theory rejects democracy as an end and treats it simply as a method. It is in opposition to thoroughgoing democracy, whose normative ends Porter supports. Its method, playing by the 'rules of the game', requires compromise and 'creates' brokerage politics, which Porter dislikes. It fears and does not allow the broadening of social participation, which Porter calls for. Finally, it furnishes a context for Porter's findings which rob them of their import. It is suggested that Porter should have treated democracy as a topic rather than as a resource. This would have allowed him to recognize the error in his rejection of liberal democracy, and would have allowed him to retain thoroughgoing democracy as a critical context with which to evaluate his findings. Furthermore, these findings would have been multiplied if he had simply used elitist democracy heuristically. Such findings and analyses, however, would have required that Porter not operate with a 'strategy of respectability.' The essay concludes with two points, both rooted in the everyday world, and both suggested as programmatic, 'external,' answers to problems in Political Sociology.

Taking into account the boundary and continuity conditions for the fluid variables, we calculate numerically the wall velocity as a function of the nucleation temperature, the latent heat, and a friction parameter. We determine regions in the space of these parameters in which detonations and/or deflagrations are allowed. In order to apply the results to a physical case, we calculate these quantities in a specific model, which consists of an extension of the Standard Model with singlet scalar fields. We also obtain analytic approximations for the wall velocity, both in the case of deflagrations and of detonations.

description: To understand the impact of low metallicities on giant molecular cloud (GMC) structure, we compare far infrared dust emission, CO emission, and dynamics in the star-forming complex N83 in the Wing of the Small Magellanic Cloud. Dust emission (measured by Spitzer as part of the S3MC and SAGE-SMC surveys) probes the total gas column independent of molecular line emission and traces shielding from photodissociating radiation. We calibrate a method to estimate the dust column using only the high-resolution Spitzer data and verify that dust traces the ISM in the HI-dominated region around N83. This allows us to resolve the relative structures of H2, dust, and CO within a giant molecular cloud complex, one of the first times such a measurement has been made in a low-metallicity galaxy. Our results support the hypothesis that CO is photodissociated while H2 self-shields in the outer parts of low-metallicity GMCs, so that dust/self shielding is the primary factor determining the distribution of CO emission. Four pieces of evidence support this view. First, the CO-to-H2 conversion factor averaged over the whole cloud is very high 4-11 \times 10^21 cm^-2/(K km/s), or 20-55 times the Galactic value. Second, the CO-to-H2 conversion factor varies across the complex, with its lowest (most nearly Galactic) values near the CO peaks. Third, bright CO emission is largely confined to regions of relatively high line-of-sight extinction, A_V >~ 2 mag, in agreement with PDR models and Galactic observations. Fourth, a simple model in which CO emerges from a smaller sphere nested inside a larger cloud can roughly relate the H2 masses measured from CO kinematics and dust.

description: We present new imaging polarimetric observations of two Main Belt asteroids, (234) Barbara and (387) Aquitania, taken in the first half of 2008 using the Dual-Beam Imaging Polarimeter on the University of Hawaii 2.2 meter telescope, located on Mauna Kea, Hawaii. Barbara had been previously shown to exhibit a very unusual polarization-phase curve by Cellino, et al. (2006). Our observations confirm this result and add Aquitania to the growing class of large inversion angle objects. Interestingly, these asteroids show spinel features in their IR spectra suggesting a mineralogical origin to the phase angle-dependent polarimetric features. As spinel is associated with calcium-aluminum-rich inclusions and carbonaceous chondrites, these large inversion angle asteroids may represent some of the oldest surfaces in the solar system. Circular as well as linear polarization measurements were obtained but circular polarization was not detected.

Evaluating management effectiveness of private forest reserve sites within the NRM South Region of Tasmania
Creators: name: Hilsendager, K
Publisher: name: University Of Tasmania
Year: 2023

description: Compared to the other Australian states, Tasmania has a high proportion of land reserved in protected areas. Despite this, many ecosystems are poorly represented in the public reserve system, due to the fact that they were some of the first areas to be come under private ownership and utilized for grazing and agricultural purposes. In order to meet Comprehensive, Adequate and Representative (CAR) reservation targets in Tasmania, protection of land within these privately owned areas is vital. There are many Private Forest Reserve Program (PFRP) sites throughout Tasmania that were established to help address this issue. However, little research evaluating management effectiveness within the program has been done up to this point. This research evaluates management effectiveness for IUCN (The World Conservation Union) category VI sites within the PFRP. It attempts to assess how well IUCN category VI objectives are being met within the program. It also evaluates whether land uses within PFRP sites are consistent with IUCN category VI management prescriptions. In addition to this, suggestions are made as to how management could be improved within the program. Four techniques were utilized to collect data for the evaluation. Firstly, a review of the operations plans and terms of covenant documents was done to assess how well plans accounted for specific management issues. Next, a questionnaire was distributed to landowners with questions focusing on ecosystem management and sustainable production. Interviews were then carried out with landowners. The interview questions were also related to ecosystem conservation and sustainable production. However, landowners were given an opportunity to go into more depth than the questionnaires. Site visits were also conducted in order to gain first hand knowledge about management issues and practice. Overall, the study found that the sites included in this investigation were managed effectively, according to IUCN management objectives. Highlights include extensive management documents and long-term protection for each site. Many landowners within the program also seemed to be fairly knowledgeable about techniques for maintaining healthy native bush. However, there were areas where improvements could be made. There were areas where management prescriptions in operations plans could have contained more detail. Additional support from DPIW could also improve management capacity in some areas, most notable exotic plant and feral animal management. Better communication between landowners and DPIW could help to ensure that management and production activities are conducted in a way that maintains natural values within each reserve.

description: N=2 superconformal many-body quantum mechanics in arbitrary dimensions is governed by a single scalar prepotential which determines the bosonic potential and the boson-fermion couplings. We present a special class of such models, for which the bosonic potential is absent. They are classified by homogeneous harmonic functions subject to physical symmetry requirements, such as translation, rotation and permutation invariance. The central charge is naturally quantized. We provide some examples for systems of identical particles in any dimension.

description: Sensory processing is hard because the variables of interest are encoded in spike trains in a relatively complex way. A major goal in studies of sensory processing is to understand how the brain extracts those variables. Here we revisit a common encoding model in which variables are encoded linearly. Although there are typically more variables than neurons, this problem is still solvable because only a small number of variables appear at any one time (sparse prior). However, previous solutions require all-to-all connectivity, inconsistent with the sparse connectivity seen in the brain. Here we propose an algorithm that provably reaches the MAP (maximum a posteriori) inference solution, but does so using sparse connectivity. Our algorithm is inspired by the circuit of the mouse olfactory bulb, but our approach is general enough to apply to other modalities. In addition, it should be possible to extend it to nonlinear encoding models.
A Tale of two sectors : practitioner perspectives on rehabilitation and working with people with complex needs
Creators: name: Graham, HM
Publisher: name: University Of Tasmania
Year: 2023

description: The prevalence of people with complex needs in both the criminal justice sector and the alcohol and other drugs sector is high and rising. This thesis analyses these two sectors in terms of how professional cultures, interagency dynamics and workforce conditions shape the rehabilitative process of working with people with complex needs. Mixed research methods are used in keeping with a strengths-based perspective, including ethnographic observation and interviews with 30 practitioners in Tasmania, Australia. Extant literature on rehabilitation paradigms, theories and models is critically analysed in terms of capacity to understand and support people with complex needs. Practitioner narratives offer evocative insights into the goodwill and passionate commitment, as well as the professional politics involved in the 'doing' of rehabilitation. It becomes clear that the two sectors have been changing in ways which affect practitioners' capacity and capital to support individuals to change. Tensions are observed between relentless change management and workforce development efforts (professionalism from above‚ÄövÑvp) in both sectors, amid the reality that significant numbers of practitioners are leaving the alcohol and other drugs sector, while disproportionate numbers of criminal justice practitioners are on leave. A principal concern in this thesis is why and how practitioners navigate complexity and change, and the influence this may have on them and those with whom they work. Concepts from the sociologies of work and the professions and the work of Pierre Bourdieu are used to analyse the field. The findings of the thesis reveal distinct differences between the literature and official accounts of rehabilitation work and the models that practitioners use, and what they actually do in practice. 'Job crafting' and hybridisation of rehabilitation work is mediated by professional ideologies and values, symbolic capital and the habitus of the helping professions. Considerable strengths and potential are identified in the Tasmanian field. Practitioners are asked about their hopes for the future, sharing ideas on how positive change and innovation might be realised in the local context. The findings show that, despite workforce changes, much has already been done to understand the drugs-crime nexus and reduce rates of recidivism and relapse. Practitioners in both sectors have extensive 'professional toolkits' and practice wisdom in helping individuals to address these problems and reduce risks of their reoccurrence. However, more can be done to build professional and systemic capacity to support recovery and desistance and, in doing so, enable more integrated, coproduced responses. Improving collaborative alliances implicates the need to address inequalities between stakeholders and re-orient the structural ordering of the field. This thesis explores the interface between recovery and desistance, and the implications for theory, policy and practice.

description: We study rational functions satisfying summability conditions - a family of weak conditions on the expansion along the critical orbits. Assuming their appropriate versions, we derive many nice properties: There exists a unique, ergodic, and non-atomic conformal measure with exponent equal to the Hausdorff dimension of the Julia set. There is an absolutely continuous invariant measure with respect to this conformal measure. The Minkowski dimension of the Julia set is strictly less than 2. Either the Julia set is the whole sphere, or the dynamics is unstable. For such polynomials and Blaschke products the Julia set is conformally removable. The connected components of the boundary of invariant Fatou components are locally connected. Finally, we derive a conformal analogue of Jakobson-Benedicks-Carleson theorem and prove the external continuity of the Hausdorff dimension of Julia sets for almost all points in the Mandelbrot set with respect to the harmonic measure. Some of the results extend to the multimodal maps of an interval.

description: Mix networks are a well-known technique to hide communication metadata, but incur a high overhead especially in group communication settings. This hinders their adoption in real-world usage, as group communication makes up a big part of modern communication patterns. In this paper, we introduce "PolySphinx", a mix format that is a step towards efficient anonymous multicasting and allows a mix node to replicate the message payload to multiple recipients. We prove that PolySphinx does not compromise on the anonymity offered to users, while considerably reducing the latency of group messages: In a group with 25 members, the average latency drops from 6.1s using the state-of-the-art Rollercoaster approach to 4.1s using PolySphinx.

description: O presente trabalho aborda o tema das políticas públicas educacionais, com ênfase na educação superior do Brasil. Este estudo exploratório, bibliográfico e documental tem como objetivo caracterizar a política pública de educação superior no Brasil, realizando uma revisão bibliográfica sobre política e políticas públicas, bem como caracterizando os marcos normativos da política educacional brasileira e suas implicações para a expansão da oferta de educação superior no país. Os resultados evidenciam que as políticas educacionais são políticas públicas de cunho social, que visam à diminuição das desigualdades sociais existentes no país, no âmbito educacional. Demonstram ainda que a Constituição Federal de 1988 e a atual Lei de Diretrizes e Bases da Educação Nacional (LDB) são instrumentos balizadores da política educacional no Brasil, tendo o Plano Nacional de Educação 2014- 2024, como o atual e principal documento para o desenvolvimento da educação nacional. Além disso, em relação à expansão da oferta da educação superior, houve significativa evolução, principalmente pela liberalização e incentivo à iniciativa privada, bem como por ações do governo federal, como o Programa REUNI.
Imagination, Autonomy and Transgression within Contemporary Fine Art Practice
Creators: name: Labern, Sally
Publisher: name: University of East London
Year: 2021

description: This practice-led research project, held by a materiality of ‘thinking through making’ on a deeply personal level, is concerned with how the autonomous imagination manifests in collaborative artistic practice, and translates into co-authored work, and the transgressions therein. The central question this research project seeks to answer is: What happens in the collaborative act of aesthetic exchange of social practice art in the context of social and political crises, and how can such acts both inform the artform, the artist and the participants? It responds to these questions through an interweaving of critical engagement with theorists and a body of work created through the research project. Its findings form a critical and reflexive expansion of my individual art practice and benefit the social practice arts sector understanding of practice though prisms of ‘surrender and running to’, ‘beholding’, ‘imminence’ and ‘the radical imagination’. The thesis explores how the imagination ruptures normative political thinking and impacts the individual and the communal through a socially engaged art practice of solo, collaborative and group performativity, framed herein as the ‘post-autonomous.’ This thesis has an alternative title of ‘Beholding the Radical Imagination: a new lens on social practice art through practice-led research'.
An examination of selected aspects of julius nyerere's political thought
Creators: name: Hawkesworth, Nigel Ross
Publisher: name: University of British Columbia
Year: 2011

description: The political thought of President Julius Nyerere of Tanzania is examined in three main contexts: the individual and society, leadership, and economic and rural development. His published writings and speeches are the main sources of information, while relevant Tanzania Government publications are also consulted. It is seen that much of Nyerere's socio-political thought rests on values and behaviour patterns inherent in African traditional society. Leadership regulations have been devised to check elitist attitudes and behaviour. Collective efforts at rural development are considered to be the only realistic way to induce socioeconomic development throughout the whole country. It is found that Nyerere has developed a consistent and comprehensive body of ideas which deal with numerous aspects of the development of his nation. His thought is used as an emotive ideology in order to mobilize the people of Tanzania to develop their country both socially and economically through co-operative living and work habits. Various problems in regard to the implementation of Nyerere's ideas are considered; the most notable being his reluctance to take strong coercive measures to ensure that his fellow politicians remain true to the spirit of the Tanzanian ideology.
