description: Nella realtà esistono già smart city con sistemi di parcheggio che offrono servizi di smart parking, ma molti di questi si basano su tecnologie costose o che richiedono una manutenzione speciale del manto stradale, con costi proibitivi per piccoli enti o per i privati. Il progetto ParkMe!, realizzato come prova finale per l'esame di Programmazione per l'Internet of Things presso l'Università degli Studi di Urbino Carlo Bo, analizza le dinamiche presenti in un qualsiasi parcheggio e vuole proporsi come soluzione alternativa low cost di smart parking, utilizzando componenti hardware tipiche dell'IoT, economiche ma efficienti, e configurazioni modulari per ridurre la complessità della manutenzione. Dopo un'attenta analisi sullo stato attuale dell'arte e sui requisiti di sistema riguardanti le dinamiche gestionali tipiche di un parcheggio, è stato realizzato un modellino in scala 1:45 con tutte le componenti necessarie alla simulazione. A tal proposito, sono stati sviluppati anche i software per l'edge e per il cloud computing e implementate le interfacce di comunicazione tra le varie parti. Lo studio condotto ha così portato alla realizzazione di una piattaforma di smart parking dinamica, modulare e a costi relativamente bassi, capace di offrire funzionalità di base come la ricerca e la prenotazione di un posto libero all'interno di un parcheggio. Tale progetto può essere facilmente replicato nella realtà purché lo si applichi all'interno di parcheggi al coperto. Da qui potranno muoversi ulteriori studi e analisi sulle dinamiche presenti all'aperto, sulle criticità riscontrabili e sulle possibili soluzioni per adattare questo progetto a qualsiasi parcheggio.

description: We examine a simple model for Pb(In$_{1/2}$Nb$_{1/2}$)O$_3$ (PIN), which includes both long-range dipole-dipole interaction and random local anisotropy. A improved algorithm optimized for long-range interaction has been applied for efficient large-scale Monte Carlo simulation. We demonstrate that the phase diagram of PIN is qualitatively reproduced by this minimum model. Some properties characteristic of relaxors such as nano-scale domain formation, slow dynamics and dispersive dielectric responses are also examined.

Imperial legitimacy in the Roman Empire of the third century : AD 193-337

description: Septimius Severus, according to Cassius Dio, told his sons to enrich the soldiers and look down on all other men (Cass. Dio 77.15.2). This recognised the perceived importance of the army in establishing and maintaining the legitimacy of an emperor. This thesis explores the role of the army in the legitimation of emperors. It also considers whether there were other groups, such as the Senate and people, which emperors needed to consider in order to establish and maintain their position as well as the methods they used to do so. Enriching the soldiers was not the only method used and not the only way an emperor could be successful. The rapid turn over of emperors after Septimius' death, however, suggests that legitimacy was proving difficult to maintain even though all emperors all tried to establish and maintain the legitimacy of their regime. The concept of legitimate authority is explained in relation to legitimacy theory put forward by Max Weber who was one of the earliest to espouse a theory of legitimacy and remains influential, although his work is not without its critics. There are three principles espoused by Weber which allowed emperors to establish and maintain their legitimacy. These are legally proclaimed authority, traditional authority and charismatic authority. By using these categories, the importance of each type to the emperors and how they sought to use them is discussed and conclusions reached about the importance of the army and other groups in the legitimation process.

description: Raman spectroscopy has been widely used in clinical and molecular biological studies, providing high chemical specificity without the necessity of labels and with little-to-no sample preparation. However, currently performed Raman-based studies of eukaryotic cells are still very laborious and time-consuming, resulting in a low number of sampled cells and questionable statistical validations. Furthermore, the approach requires a trained specialist to perform and analyze the experiments, rendering the method less attractive for most laboratories. In this work, we present a new high-content analysis Raman spectroscopy (HCA-RS) platform that overcomes the current challenges of conventional Raman spectroscopy implementations. HCA-RS allows sampling of a large number of cells under different physiological conditions without any user interaction. The performance of the approach is successfully demonstrated by the development of a Raman-based cell viability assay, i.e., the effect of doxorubicin concentration on monocytic THP-1 cells. A statistical model, principal component analysis combined with support vector machine (PCA-SVM), was found to successfully predict the percentage of viable cells in a mixed population and is in good agreement to results obtained by a standard cell viability assay. This study demonstrates the potential of Raman spectroscopy as a standard high-throughput tool for clinical and biological applications.

description: We calculate the two-time current correlation function using the experimental data of the current-time characteristics of the Gas-DNA-decorated carbon nanotube field effect transistor. The pattern of the correlation function is a measure of the sensitivity and selectivity of the sensors and suggest that these gas flow sensors may also be used as DNA sequence detectors. The system is modelled by a one-dimensional tight-binding Hamiltonian and we present analytical calculations of quantum electronic transport for the system using the time-dependent nonequilibrium Green's function formalism and the adiabatic expansion. The zeroth and first order contributions to the current $I^{(0)}(\bar{t})$ and $I^{(1)}(\bar{t})$ are calculated, where $I^{(0)} (\bar{t})$ is the Landauer formula. The formula for the time-dependent current is then used to compare the theoretical results with the experiment.

description: We introduce a new method to detect the absolute neutrino mass scale. It uses a macroscopic mass of tritium source. We explain that the neutrino mass can be measured by scaling the mass difference of the source between initial and final state, and its heat value. This method is free from the electron energy resolution limit and the statistical error. We estimate the required accuracy to measure the neutrino mass. We also report that the {u,d} component of the CKM matrix, |V(ud)| may be determined in 10^-6 accuracy as an application of this work.

Finding the secret river : mapping a composite narrative of the secret river and searching for the secret river
Creators: name: Boulanger-Mashberg, AL
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis conducts a close reading of Kate Grenville's two recent texts, the historical novel The Secret River and its companion writing memoir‚ÄövÑvp Searching for the Secret River. The first text rewrites an Australian colonial history while the second inscribes a personal, biographical history. I argue for a paired reading of the texts, which broadens the novel's historical concerns, encompassing Searching for the Secret River's contemporary anxieties about place. This reading constructs a composite narrative which is a representation of postcolonial as well as colonial experience. It also enables a decentring of the persistent controversies regarding Grenville's claims for her novel's historical veracity. The Secret River has featured notoriously in a contemporary Australian debate about the ethical responsibilities of novelists appropriating historical fact. However, a focus on this public and academic debate over disciplinary boundaries has dominated commercial and critical reception of The Secret River, obscuring other aspects of the novel. In establishing a composite reading, this thesis examines one such aspect: the narrative's preoccupation with the notion of belonging. Chapter one maps the composite narrative across the two texts, differentiating, as well as emphasising the connections between, the journeys of each text's central character. The chapter dissects the characters' individual and common experiences of belonging, while tracing several recurrent themes ‚Äö- including the contested power of literacy and orality ‚Äö- through the composite narrative. The characters' relationships to land are considered as expressions of postcolonial anxiety, after Alan Lawson's discussions of settler narrative tropes. In chapter two I explore the composite narrative's representations of belonging with a temporal rather than a geographical approach, identifying a nostalgia which is present both formally and thematically. The notion of a literary postcolonial belatedness underpins this argument, facilitating an examination of Grenville's relentless rehearsal of not only national but personal histories. The final chapter broadens the scope of the thesis to include Grenville's earlier historical novel, Joan Makes History, as well as two contemporary fictionalisations of Australian history ‚Äö- Lindsay Simpson's The Curer of Souls and Richard Flanagan's Gould's Book of Fish. A discussion of the presence of a historiographic self-consciousness in each of these texts contextualises the composite narrative's approach to harnessing historical fact. The thesis concludes that the paired reading allows a more complex investigation of The Secret River than a reading of the novel alone.

description: As electric vehicles gain popularity, hydrogen fuel cell technology is emerging as a promising alternative. With superior efficiency and eco-friendliness compared to gasoline engines, hydrogen fuel cells offer a cleaner and more sustainable way to power EVs. The technology has come a long way in recent years, with car manufacturers such as Toyota, Honda, and Hyundai investing heavily in research and development. While the high cost of production remains a challenge, the potential benefits of hydrogen fuel cells in the long term make it an exciting area to watch for the future of sustainable transport.
title: Echoes of endlessness : time, memory, and experience for heroin users in Scotland
Creators: name: Roe, Laura
Publisher: name: University of St Andrews
Year: 2020

description: Drawing on ethnographic research conducted from September 2016 to September 2017 in a county on the east coast of Scotland, this thesis explores heroin and poly-substance use in relation to time, temporality, and memory. The research took place within an array of recovery services and with individual heroin users, largely employing participant observation and interview methodologies. The first seven months of the research were primarily based in services, for the most part consisting of a third sector needle exchange, a community recovery group, and an under 25s drop-in centre. The latter five months were spent accompanying one scattered group of heroin users in their day to day lives. In the context of substance use patterns specific to post-industrial Scotland, and among the highest drug-death rates in Europe, the thesis traces time as it becomes entangled with addiction and recovery across intimate, social, and institutional domains. It seeks to excavate related experiences of grief, loss, and trauma, as well as affect, intimacy, and pleasure. The thesis explores perceptions and experiences of unending repetition, which were tied to prevailing medical models of addiction and contradictions inherent in predominant constructions of recovery. In spite of their repetitiveness, however, time and broader life trajectories come to be so incoherent and complex that they are immensely difficult to trace, interpret, and express: for both heroin users and for the myriad medical, judicial, and recovery-oriented institutions they interacted with daily. The work overall attempts to give an ethnographic portrait of how heroin addiction and poly-substance use are composed in time, memory, history, and landscape, while examining contemporary approaches to addiction and recovery in Scotland.
Analytical survey of the Pemberton Valley in British Columbia with special reference to adult education
Creators: name: Dickinson, James Gary
Publisher: name: University of British Columbia
Year: 2011

description: The study problem was to analyze adult education participation in a rural community in conjunction with a detailed survey of the community and its residents. Three hypotheses were tested to ascertain whether or not there were any significant differences between adult education participants and non-participants with respect to socio-economic characteristics, social interaction patterns, and locality of residence. The analytical survey method was used and the principal means of data collection was the personal interview. One hundred fifty-eight non-Indian household heads and a sample consisting of thirty-two native Indian respondents were interviewed. The community studied was the Pemberton Valley in British Columbia which is an isolated mountain valley one hundred miles northeast of Vancouver. Approximately one-fifth of the non-Indian respondents were classified as farm while the remainder were not engaged in agriculture. In general, the non-Indian population had similar characteristics to the residents of other rural areas in the province. They had a median of nine to eleven years of school completed, an average annual income of slightly less than $6, 000, and worked mainly in unskilled and semi-skilled occupations. The Indians by comparison had less education, lower incomes, and were marginal in the labour force. Systematic adult education in Pemberton was limited almost exclusively to night school courses. Twenty-three courses offered between 1964 and 1966 had a total enrollment of 352 adults. Some 22. 2 per cent of the non-Indian respondents had taken at least one course within the three year period. There were statistically significant differences between the adult education participants and the non-participants with respect to nine socio-economic characteristics studied including age, number of children at home, birthplace, number of years resident in the area, number of related families living in Pemberton, farm or non-farm resident, father's education, perceived adequacy of skills, and desire for further education or training. Of the social interaction characteristics studied, social participation and road opinion differentiated between the participants and the non-participants. Locality of residence was related to adult education participation and the number of respondents who participated decreased as distance from the nightschool center increased.

description: Background—Despite advances in the management of subarachnoid hemorrhage, a considerable proportion of patients are still left with severe and disabling long-term consequences. Unfortunately, there arelimited therapeutic options to counteract the sequelae following the initial insult. The role of stem cells hasbeen studied in the treatment of various diseases. The goal of this study was to provide a literature reviewregarding the potential advantages of stem-cell therapy to counteract or minimize the sequelae of aneurysmal subarachnoid hemorrhage.Methods—PubMed, Google Scholar, and ClinicalTrials.gov searches were conducted t o incorporate pertinent studies that discussed stem cell use in the management of subarachnoid hemorrhage. Included articleswere subjected to data extraction for the synthesis of the efficacy of stem-cell therapy.Results—Four preclinical studies with 181 animal model subjects (44 mice, 137 rats) were incorporatedin our review. Endovascular punctures (65%) and blood injections in subarachnoid spaces (17%) were usedto induce hemorrhage models. Stem cells were administered intravenously (3.0 × 106cells) or intranasally(1.5 × 106 cells). According to literature, mesenchymal cell therapy significantly (p<0.05) induces stemcell migration to lesion sites, decreases associated neural apoptosis and inflammation, improves ultrastructural integrity of cerebral tissue, and aids in improving sensorimotor function post subarachnoid hemorrhage.Concl

Metal catalysed acetylene oligomerisation
Creators: name: Karpiniec, SS
Publisher: name: University Of Tasmania
Year: 2023

description: The oligomerisation of acetylene by metal catalysts has been investigated as a potential route to liquid products, in the context of Gas-to-Liquid generation of petrochemicals. The catalysts trialled are known for their high activities in the polymerisation and oligomerisation of ethylene. Group III, IV and V metallocenes `Cp_2MCl_n` `(M = Sc, Y, n = 1; M = Ti, Zr, Hf, V, n = 2)`, `Cp`\\(^*\\)\\( _2\\)`YCl*THF` and `[Cp`\\(^*\\)\\( _2CeCl]_n\\) were activated with a range of alkyl aluminium cocatalysts, `MAO` and `AlEt_xCl_(3-x)` `(x = 2,3)`, and exposed to acetylene. Diimine complexes of nickel and palladium were also trialled, as were a small range of chromium complexes, in the presence of MAO. Activities were extremely low for all of these complexes, except in the presence of AlEt3, where some light oligomers were produced (`C_4, C_6`). Further studies showed that growth occurred at `AlEt_3` itself, and that the transition metals were ineffective. Elevated temperatures and extended run times produced a complex range of oligomeric and polymeric products, some of which were identified with the use of GC-FID and GC-MS. Oligomer growth is slow, and branching is introduced at an early stage; several proposals as to the mechanism of growth were suggested. The use of hydrogen gas and high metallocene concentrations failed to provide effective chain transfer activity. This system was explored theoretically using DFT methods, which showed that dimeric aluminium species impede product growth beyond the first insertion; crystallographic evidence also supported this claim. The use of AlEtCl2 as an activator led to the copolymerisation of acetylene and aromatic solvents, and the nature of this process and the formed polymer were investigated in more detail. Bis(imino)pyridineiron(II) catalysts were trialled with acetylene, displaying high initial activity but quick deactivation. The catalyst containing 2,6-diisopropylphenyl substitution produces polyacetylene, as well as oligomers in the presence of the chain transfer agent `ZnEt_2`. The oligomer array is complex and was investigated by GC-FID and GC-MS; a mechanism is proposed for the formation of identified compounds. The use of more `ZnEt_2` generates a higher proportion of oligomer, but slows catalyst activity. Catalyst deactivation was investigated by SEM and ICP-MS, and found to be due to encapsulation within the insoluble polyacetylene. The catalyst was not able to effective co-polymerise acetylene and ethylene. The ortho-tolyl substituted catalyst primarily forms benzene from acetylene (cyclotrimer). Deuterium labelling studies suggest cyclotrimerisation via a metallocyclic mechanism, which is interrupted in the presence of the `ZnEt_2`. Hydrogen was not effective as a chain transfer agent for the iron catalysts.
Typology of poverty

Publisher: name: University of British Columbia
Year: 2011

description: This study is an attempt to discover relationships between particular factors which we felt would be indicators of poverty. Of the many factors suggested by the literature of poverty, we investigated relationships between income level, employment status, health conditions, education level, and age. Using the Vancouver data collected by the Nu-life Study, we designed a program which would indicate the nature and strength of the relationship between these factors. From a definition of our variables, a model was designed using as a basis income adequacy. The available data contained information on other variables which we used, such as - marital status, sex, and number of persons per household. From this the hypothetical construct was formulated around hypotheses relating to four groups which were configurations of the employment status and income adequacy variables. Our statistical analysis was based on the chi square method for measuring significance and consistency. The contigency co-efficient was employed to measure the relatedness of the variables. We found that there were indeed positive links between the factors referred to. However, these links were not as strong as we had anticipated. Although the project could not establish cause-effect relationships, the findings do help to establish some of the components in the poverty cycle. These components would not seem to have equal strength in determining level of income. Further research might investigate why some of these factors had greater bearing on income level than others. For example, the level of education seemed to have a greater effect than did the health factor. Consequently, we see this study as a step in determining the characteristics of poverty.

description: The aim of the study was to evaluate the stability of vitamin C and beta-carotene in the freeze-drying process compared to other thermal drying methods. Tomato puree was selected as a model product for testing the stability of vitamin C and vitamin A in drying processes, due to its properties, such as: appropriate consistency, which was favorable for the analyzes performed, and the presence of the above-mentioned vitamins. Model studies were performed on the stability of vitamin C and beta-carotene under the conditions of air-drying at 105°C, drying under reduced pressure at 70°C and freeze-drying on a tomato puree matrix. Results proved that freeze-drying is superior to other drying methods with the lowest losses of both vitamin C (losses of 4%) and beta-carotene (losses of 25%) in tomato purée. In the case of drying at 70°C under reduced pressure, the loss of beta-carotene is 55%, and vitamin C – 78%. In the case of air-drying at 105°C, vitamin C is 100% degraded, and the loss of beta-carotene is 91%. Moreover, it can be concluded that vitamin C in a higher dose has a protective effect on carotenoids.

It remainsunclear whether certain thrombus characteristics resultin resistance to lysis with IV rt-PA. In animal models ofembolic stroke and femoral artery thrombosis, whitethrombi composed of platelets and fibrin displayed a relative resistance against thrombolysis, whereas erythrocytes-rich (red) thrombi were more vulnerable to lysis[4]. Platelet-rich thrombi were relatively resistant to rtPA compared with in a rabbit model of femoral arterythrombosis [5]. Furthermore, thrombolytics exposureresults in platelet activation, which increases the plateletcontent in thrombus and thus render thrombus resistantto additional thrombolytic activity
Mass transport and changes in the saccharide profile during osmotic dehydration of apricot and chokeberry fruits

description: Abstract: The aim of the study was to determine the effect of osmotic dehydration in sucrose solution on the level and profile of the main saccharides in frozen chokeberry and apricot. A 50°Bx sucrose solution at a temperature of 25, 35, 45 and 55°C was used in the tests. The influence of temperature and dehydration time on the dry matter content in the tested fruits was demonstrated. Both in apricot and chokeberry the highest increase was recorded in the first hour of the process, for apricots to the level of 25.1-32.4%, for chokeberry 30.4-33.4%. The use of the highest temperature (55°C) increased the content of glucose and fructose while reducing the amount of sucrose (hydrolysis); at 25-35°C the opposite effect was obtained. At low temperatures, chokeberry was not very susceptible to migration of sucrose. Also, the transport of water was not intense. There was no correlation between the temperature of the process and the increase in dry matter in the sample. The greatest loss of water, i.e. 1 g H2O/g i.d.m., occurred after five hours at 55°C. Under analogous conditions, apricots showed a higher water loss, at the level of 4.68 g H2O/g i.d.m. At 25°C, after the first hour of dehydration, the energy value of saccharides in apricots was 315 kJ/100 g; at 55°C, after 3÷5 hours it fluctuated around 500 kJ/100g. Dehydrated chokeberry was characterized by approx. 1.5÷2 times lower energy value than apricot.

description: We present a Monte Carlo study of dijet angular distributions at $\sqrt{s}=14$ TeV. First we perform a next-to-leading order QCD study; we calculate the distributions in four different bins of dijet invariant mass using different Monte Carlo programs and different jet algorithms, and we also investigate the systematic uncertainties coming from the choice of the parton distribution functions and the renormalization and factorization scales. In the second part of this paper, we present the effects on the distributions coming from a model including gravitational scattering and black hole formation in a world with large extra dimensions. Assuming a 25% systematic uncertainty, we report a discovery potential for the mass bin $1 < M_{jj} < 2$ TeV at 10 pb$^{-1}$ integrated luminosity.

description: The present investigation aimed to evaluate the effect of noodles supplementation with oggtt at (5,10,15 and 20%) on physicochemical properties, antioxidant activity as well as volatile compounds. The cooked noodles evaluation based on cooking quality like volume and cooking loss as well as colour changes. An increase in protein, fat and ash was observed with the increase of oggtt supplementation level in noodles. The whole wheat flour had the highest value of total phenolic (462.3 μg GAE g−1) compared to oggtt and all fortified noodles without cooking and after cooking. The fortification levels of 5 and 10% did not affect significantly on colour and overall acceptability of noodles. The panelists scores recommended the usage levels of 5 and 10% of oggtt noodles which did not changed significantly in comparison with control sample. The evaluation of oggtt incorporation in noodles volatile compounds performed using HS-GC/MS analysis. Thirty volatile compounds in cooked noodles after fortification with oggtt had identified. The main volatile compound herein was 2-pentyl furan, which represent 44.12, 20.14 and 18.75% in cooked control and fortified noodles with oggtt at 5 and 10% respectively.

description: We experimentally demonstrate a quantum walk on a line in phase space using one and two trapped ion. A walk with up to 23 steps is realized by subjecting an ion to state-dependent displacement operations interleaved with quantum coin tossing operations. To analyze the ion's motional state after each step we apply a technique that directly maps the probability density distribution onto the ion's internal state. The measured probability distributions and the position's second moment clearly show the non-classical character of the quantum walk. To further highlight the difference between the classical (random) and the quantum walk, we demonstrate the reversibility of the latter. Finally, we extend the quantum walk by using two ions, giving the walker the additional possibility to stay instead of taking a step.

We introduce the appropriate supersymmetric generalizations of the conventional entanglement measures for the cases of $n=2$ and $n=3$. In particular, super-Greenberger-Horne-Zeilinger states are characterized by a nonvanishing superhyperdeterminant.

description: A search for the Z(3930) resonance in gamma gamma production of the DDbar system has been performed using a data sample corresponding to an integrated luminosity of 384 fb^-1 recorded by the BABAR experiment at the PEP-II asymmetric-energy electron-positron collider. The DDbar invariant mass distribution shows clear evidence of the Z(3930) state with a significance of 5.8 sigma. We determine mass and width values of (3926.7 +- 2.7 +- 1.1) MeV/c^2 and (21.3 +- 6.8 +- 3.6) MeV, respectively. A decay angular analysis provides evidence that the Z(3930) is a tensor state with positive parity and C-parity (J^PC = 2^++); therefore we identify the Z(3930) state as the chi_c2(2P) meson. The value of the partial width Gamma_(gamma gamma)xB(Z(3930)-> DDbar) is found to be (0.24 +- 0.05 +- 0.04) keV.

description: Tidal charged spherically symmetric vacuum brane black holes are characterized by their mass m and tidal charge q, an imprint of the 5-dimensional Weyl curvature. For q>0 they are formally identical to the Reissner-Nordström black hole of general relativity. We study the thermodynamics and thermodynamic geometries of tidal charged black holes and discuss similarities and differences as compared to the Reissner-Nordström black hole. As a similarity, we show that (for q>0) the heat capacity of the tidal charged black hole diverges on a set of measure zero of the parameter space, nevertheless both the regularity of the Ruppeiner metric and a Poincaré stability analysis shows no phase transition at those points. The thermodynamic state spaces being different indicates that the underlying statistical models could be different. We find that the q<0 parameter range, which enhances the localization of gravity on the brane, is thermodynamically preferred. Finally we constrain for the first time the possible range of the tidal charge from the thermodynamic limit on gravitational radiation efficiency at black hole mergers.

description: At the 2008 Summer Olympics in Beijing, Usain Bolt broke the world record for the 100 m sprint. Just one year later, at the 2009 World Championships in Athletics in Berlin he broke it again. A few months after Beijing, Eriksen et al. studied Bolt's performance and predicted that Bolt could have run about one-tenth of a second faster, which was confirmed in Berlin. In this paper we extend the analysis of Eriksen et al. to model Bolt's velocity time-dependence for the Beijing 2008 and Berlin 2009 records. We deduce the maximum force, the maximum power, and the total mechanical energy produced by Bolt in both races. Surprisingly, we conclude that all of these values were smaller in 2009 than in 2008.
Social class and treatment in Burnaby Mental Health Centre
Creators: name: Felker, Melvyn B.
Publisher: name: University of British Columbia

description: Concern about mental health is on the increase in North America. Increased concern necessitated the provision of more treatment facilities for mental illness. For this reason, research is being conducted in the mental health field. This study is the first undertaken in Canada, in an attempt to investigate a possible relationship between social class and mental illness. The study focussed on social class and treatment in a mental health setting at the Mental Health Centre, Burnaby, and comparisons were made with studies done in the United States. Data were made available through the B. C. Department of Vital Statistics. These data were collected at the Mental Health Centre, Adult Clinic, Burnaby from April 1, 1959 to March 31, 1964. As the data were not collected by the researchers, there are limitations which are discussed in the study. Of the total number of persons seen at the Adult Clinic, 1231 were given treatment and terminated during this five year period. These were the subjects of this study. The findings reveal no significant relationship between social class and the kind of treatment, or, between social class and the length of treatment. However, the findings do indicate that diagnosis is related to both social class and assignment of a therapist.
An Australian composer abroad : Malcolm Williamson and the projection of an Australian identity
Creators: name: Philpott, Carolyn
Publisher: name: University Of Tasmania
Year: 2023

description: Malcolm Williamson (1931-2003) was one of the most successful Australian composers of the latter half of the twentieth century and the depth, breadth and diversity of his achievements are largely related to his decision to leave Australia for Britain in the early 1950s. By the 1960s, he was commonly referred to as the most commissioned composer in Britain‚ÄövÑvp and in 1975 he was appointed to the esteemed post of Master of the Queen's Music. While his service to music in Britain is generally acknowledged in the literature, the extent of his contribution to Australian music is not widely recognised and this is the first research to be undertaken with a strong focus on the identification and examination of the many works he composed for his homeland and his projection of an Australian identity through his music and persona. This study draws on previously-unexplored primary source material, including correspondence and manuscript scores, to support the assertion that Williamson projected an Australian identity and to provide insight into the construction and manifestations of that persona and the effect that these elements had on the reception of his works. Major works examined in this study include Symphony for Voices (1960-62), The Display (1964), the Sixth (1982) and Seventh (1984) symphonies, The True Endeavour (1988) and The Dawn is at Hand (1989). To place the discussion of Williamson's expressions of national identity in context, the composer's expatriate experience and views of his homeland are examined and compared to the journeys and opinions of numerous other high-profile Australian expatriate creative artists. Significantly, many parallels are discovered that can be interpreted as characteristics of the reverse-migration experience and are indicative of the prevailing cultural attitudes towards Australian expatriates during the twentieth century; confirming that Williamson's situation was not particularly unique. This research has permitted a reassessment of Williamson's creative life and work and as a result, his contribution to Australian music can now be contextualised and more comprehensively understood and acknowledged.

description: It is known that unstable periodic orbits of a given map give information about the natural measure of a chaotic attractor. In this work we show how these orbits can be used to calculate the density function of the first Poincaré returns. The close relation between periodic orbits and the Poincaré returns allows for estimates of relevant quantities in dynamical systems, as the Kolmogorov-Sinai entropy, in terms of this density function. Since return times can be trivially observed and measured, our approach to calculate this entropy is highly oriented to the treatment of experimental systems. We also develop a method for the numerical computation of unstable periodic orbits.

Transformations of triangle ladder diagrams

description: It is shown how dual space diagrammatic representation of momentum integrals corresponding to triangle ladder diagrams with an arbitrary number of rungs can be transformed to half-diamonds. In paper arXiv:0803.3420 [hep-th] the half-diamonds were related by conformal integral substitution to the diamonds which represent the dual space image of four-point ladder integrals in the four-dimensional momentum space. Acting in the way described in the present paper we do not need to use the known result for diamond (four-point) diagrams as an external input in deriving relations of arXiv:0803.3420 [hep-th], however, that result for the diamond diagram arises in the present proof as an intermediate consequence in a step-by-step diagrammatic transformation from the triangle ladder diagram to the half-diamond diagrams.
