description: We report the first attempt to observe the secondary eclipse of a transiting extra-solar planet at radio wavelengths. We observed HD 189733 b with the Robert C. Byrd Green Bank Telescope of the NRAO over about 5.5 hours before, during and after secondary eclipse, at frequencies of 307 - 347 MHz. In this frequency range, we determine the 3-sigma upper limit to the flux density to be 81 mJy. The data are consistent with no eclipse or a marginal reduction in flux at the time of secondary eclipse in all subsets of our bandwidth; the strongest signal is an apparent eclipse at the 2-sigma level in the 335.2 - 339.3 MHz region. Our observed upper limit is close to theoretical predictions of the flux density of cyclotron-maser radiation from the planet.

Multidimensional separation approaches for complex sample analysis : two-dimensional ion chromatography ‚Äöv¿vØ capillary electrophoresis
Creators: name: Ranjbar Shourabi, L
Publisher: name: University Of Tasmania
Year: 2023

description: The work presented in this thesis describes development, evaluation and implementation of an online interfacing/modulation technique for comprehensive two-dimensional ion chromatography ‚Äöv¿vØ capillary electrophoresis (IC ‚Äöv¿vØ CE) separation of low-molecular-mass ionic or ionogenic compounds. Chapter 1 provides an insight into the evolution of multidimensional liquid-phase separations combining both chromatography and electrophoresis from inception in 1948 to present. As noted in this chapter, column-based multidimensional electrophoretic and chromatographic separations have shown to be powerful complementary techniques to the traditional two-dimensional gel-electrophoresis approaches; especially for the analysis of lower molecular-mass-molecules in addition to proteins and peptides. However, complexities in instrumentation and online interfacing technologies are known to have hindered development of such techniques. Chapter 2 introduces a non-focusing interfacing technology for online hyphenation of ion chromatography with capillary electrophoresis. The system compromised of an in-house sequential-injection capillary instrument which, through the use of a two-position six-port injection valve, allowed comprehensive sampling of the IC effluent for quantitative analysis of inorganic anions and haloacetic acids in water. In addition to instrumental developments, the second section of this thesis focuses on alternative method development approaches for screening/optimisation of IC ‚Äöv¿vØ CE separations. Chapter 3 demonstrates the impact of background electrolyte pH on sample dimensionality and peak capacity for IC ‚Äöv¿vØ CE separation of multi-valent lowmolecular-mass organic acids. In this chapter, a simplified screening approach based on calculation and maximising of Euclidean distance between the two-dimensional peaks was used to predict the optimal background electrolyte pH in CE as well as the eluent profile in IC. However, due to lack of overall two-dimensional selectivity, further investigations were necessary to make full resolution of the analytes possible. In Chapter 4, based on a ground set by the findings presented in Chapter 3, a universal framework is proposed for simultaneous screening of separation selectivity in both dimensions as a preceding step in method development/optimisation of twodimensional separations. In this chapter, through the introduction of the concept of two-dimensional selectivity mapping, effect of stationary phase in IC and background electrolyte pH in CE on the overall two-dimensional separation selectivity was studied to enable full resolution of the organic acids. Finally, Chapter 5 of this thesis discusses the limitations of IC ‚Äöv¿vØ CE and provides further insight and direction for future research.

description: Utilizing three-terminal tunnel emission of ballistic electrons and holes, we have developed a method to self-consistently measure the bandgap of semiconductors and band discontinuities at semiconductor heterojunctions without any prerequisite material parameter. Measurements are performed on lattice-matched GaAs/AlxGa1-xAs and GaAs/(AlxGa1-x)0.51In0.49P single-barrier heterostructures. The bandgaps of AlGaAs and AlGaInP are measured with a resolution of several meV at 4.2 K. For the GaAs/AlGaAs interface, the measured Gamma band offset ratio is 60.4:39.6 (+/-2%). For the GaAs/AlGaInP interface, this ratio varies with the Al mole fraction and is distributed more in the valence band. A non-monotonic Al composition dependence of the conduction band offset at the GaAs/AlGaInP interface is observed in the indirect-gap regime.

description: Recent advances in legislation across the world require influencers on social media to disclose advertisements clearly. The execution of these regulations faces multiple problems, one of which arises through the sheer mass of trillions of posts. The need for automated detection of undisclosed advertisements has fueled an entire research field. As computers do not directly understand human language, classification in general and explainability of these classifications in particular have proven a hard task historically. With the recent emergence of large language models, a new generation of computational tools have become available that can comprehend and process even nuanced variations in language. In my capstone I investigate the applicability of such language models, in particular various models of the GPT-3 series, GPT-3.5-turbo and GPT-4. I use various instruction techniques, parameter settings and context variations. Moreover I study the extent to which humans perform at this task. I find that all of these models show substantial capacity to discriminate between ads and non-ads. Moreover I find that human-generated labels are severely limited in quality but can be improved if humans are assisted by ChatGPT. In a series of experiments, I show that both GPT-3.5 and GPT-4 achieve a performance near the theoretical maximum from human reproducibility.

Une etude des lazzi visuels et verbaux dans le theatre de Moliere
Creators: name: Dickinson, Barbara Helen
Publisher: name: University of British Columbia
Year: 2011

description: La commedia dell'arte italienne eut une profonde influence sur Molière à cause de son jeu-improvisé, et cela en partie à cause des "lazzi." II s'agit d'é́pisodes fragmentaires, de "tours" comiques qui évoquent le rire d'une façon visuelle ou verbale. En nous basant sur les canevas de Flaminio Scala, le manuscrit de Dominique Biancolelli, et la collection des lazzi de P.D. Placido Adriani, nous faisons une étude systématique du rôle des lazzi dans le théâtre moliéresque. Nous étudions les pièces de Molière qui incarnent le mieux cet aspect, celles composées d'un ou de trois actes, formes plus typiques de la farce que de la "grande" comedie. Nous commençons par ces bouffonneries physiques qui prȩ́sentent quelques émotions primitives de la comédie. Nous examinons ensuite les émotions humaines exprimées selon les formules des cérémonies de la politesse. Dans ces lazzi les personnages, soit consciemment, soit inconscieminent, s'adaptent mal aux cérémonies prescrites par la société. Ensuite il s'agit des "cérémonies" des médecins, les gestes et le jargon qui servent à exploiter la crédulité des clients. Nous examinons en plus de détail d'autres lazzi verbaux qui créent un effet comique à cause de la manière déformée et outrée dont le son de la voix s'exprime: les sons inarticulés des émotions, l'imitation des sons purs, le patois ou tout autre "style" de parler, et la répétition. On fait contraster la lenteur et la rapidité ou la difficulté et la facilité avec laquelle on parle. Nous revenons à notre étude des lazzi visuels dans cette situation fondamentale où un personnage ne se rend pas compte de la présence d'un autre. II y en a plusieurs variations mais il s'agit toujours du rapport entre deux personnages sur la scène, c'est-à-dire le manque de conscience réel ou feint de la présence d'un autre. Enfin il y a les jeux de scène qui font ressortir les deux aspects d'un personnage: la réalité, et Presque simultanément, le déguisement. Molière emprunte de toutes mains les lazzi de la commedia dell'arte en les employant sans honte mais en évitant leur vulgarité. Molière associe les lazzi aux personnages masqués: les vieillards et les domestiques. Cependant, il trace une ligne de démarcation entre les scènes de vrai comique et les épisodes sentimentaux. Les jeux de scène comiques s'adaptent à la structure des comédies moliéresques qui ressemble à celle de la parade. Au début des pièces le lazzi rend l'exposition vivante, et au dénouement il illumine la scène d'un dernier feu. Comme les Italiens, Molière veut évoquer le rire, mais sa grande originalité se manifeste dans cette fusion de la parole et de la mime qui apporte une révélation morale du caractère d'un personnage

Early childhood programs for social inclusion : examining cognitions, emotions and social dispositions
Creators: name: Ac, R
Publisher: name: University Of Tasmania
Year: 2023

description: Currently, in Australia and overseas, the term social inclusion‚ÄövÑvp is widely used within social policy to inform thinking and practice as a means to reduce inequalities. In the area of education policy, a key goal is to strengthen social inclusion by encouraging parents with pre-school children to engage in socio-educational and community support services. Early Childhood Education and Care (ECEC) programs strive to provide equal opportunities for all children and particularly target families at risk of exclusion. This research examines whether social skill acquisition can be assumed as mostly a cognitive choice/awareness or if emotional influences prevail and inhibit social inclusion for some people. It is argued that social policy strategies and educational practices may benefit from two theoretical approaches: Bourdieu's notion that a person's social dispositions can elicit exclusion if not conducive with dominant culturally-defined expectations; and Bowlby's attachment theory, explaining the emotional foundation of social inclusion and exclusion. Qualitative research methods, involving practitioner interviews and parent discussions, were used in this research to develop some understandings about the facilitation of social inclusion. Data were collected across two sites, Launching into Learning (LiL) and Child and Family Centres (CFCs), both situated in low socio-economic (SES) areas in Tasmania, Australia. Major themes arising from the data were theoretically analysed by applying sociological and attachment theories. The overall findings were that regularly participating parents appeared cognitively aware of the benefits and chose to engage in the programs with an expectation of socio-educational rewards for both themselves and their children. Conversely, those who were disinclined to participate seemed to experience negative emotional feelings in unfamiliar social groups/settings. This research is significant as it extends and refines understanding of the emotional side of social inclusion. A more in-depth understanding of the emotional aspect of social inclusion, within ECEC approaches, is hoped to strengthen participation in early childhood/family support programs.
Cost effective renewable energy integration within remote and isolated power systems via low-load diesel application
Creators: name: Hamilton, James
Publisher: name: University Of Tasmania
Year: 2023

description: Reliable and affordable electricity supply within remote and isolated power systems presents both unique opportunities and challenges. In part, the challenges result from a lack of central network infrastructure and a reliance on diesel fired generation. Unfortunately, the cost of supplying diesel to these communities is high and rising. Opportunities within remote and isolated systems include renewable energy integration, with renewable energy one technology able to reduce both the cost and pollution of diesel generation. To successfully integrate renewable energy technologies, both the stochastic nature of the renewable energy resource, and the operating characteristics of diesel generation require consideration. Typically, diesel generation is configured to run at fixed speed and load, achieving peak efficiencies within 70-80% of rated capacity. Diesel generation is also commonly sized to peak demand, reducing system flexibility. In order to successfully integrate renewable energy, the system requires flexibility. While energy storage is conventionally integrated to improve system flexibility, this step adds cost and complexity to the system. An alternative approach exists in redefining the low-load capability of diesel generation. Low-load diesel allows a diesel engine to operate across its full capacity in support of improved renewable energy utilisation. As low-load diesel applications rely entirely on the capabilities of existing diesel assets, they promise a low cost, low complexity substitute. This thesis explores low-load diesel application, identifying a substantial role for the approach in addressing many of the barriers currently observed to high renewable energy penetration architectures. In recommending low-load diesel application as a precursor to energy storage integration, the system, economic and environmental impacts of low-load diesel application are quantified. The results identify a novel pathway for consumers to transition from low to medium levels of RE penetration, without additional cost or system complexity.

The obtained Q moment, |Q_exp(31Al)| = 112(32)emb, are in agreement with conventional shell model calculations within the sd valence space. Previous result on the magnetic moment also supports the validity of the sd model in this isotope, and thus it is concluded that 31Al is located outside of the island of inversion.

Paving the practical pathway : the place of gifted education pedagogy in undergraduate clinical skills education in Australia
Creators: name: Harper, Amanda
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis aims to explore factors which enhance clinical skills acquisition in undergraduate healthcare education in the disciplines of Medicine, Paramedicine and Pharmacy at the University of Tasmania, Australia. This is achieved through an exploration of relevant gifted education pedagogy. The local and national healthcare context provides the platform for tertiary education across these disciplines. Within this, students from the University of Tasmania develop clinical skills which align theoretical, biologically-based knowledge and diagnostic skills with communication and interpersonal skills. This thesis presents a rationale for identifying such students as academically gifted learners, which intrinsically ties gifted education pedagogy to undergraduate healthcare study. Through a phenomenological, mixed-methods approach this thesis investigates empathic responding, academic self-concept, and the Big Fish Little Pond Effect in the target cohort. Results of the study suggest that: demographic characteristics may predict levels of empathic responding; there are no clear links between academic self-concept and levels of empathic responding to well-developed clinical skills; and, demographic characteristics may also predict levels of clinical skills. There is evidence of the Big Fish Little Pond Effect amongst participants, particularly those studying Medicine. Further examination of the results through the lens of Kazimierz D¿ívñbrowski's Theory of Positive Disintegration suggests that an understanding of the levels of development, particularly with reference to the Syntonic Continuum, may inform the design of appropriate pedagogical strategies to support empathic development in students and assist in mitigating against empathic decline or compassion fatigue. These results suggest that gifted education pedagogy has a vital place within the learning and teaching of undergraduate healthcare education.

A Binary Origin for Blue Stragglers in Globular Clusters

description: Blue stragglers in globular clusters are abnormally massive stars that should have evolved off the stellar main sequence long ago. There are two known processes that can create these objects: direct stellar collisions and binary evolution. However, the relative importance of these processes has remained unclear. In particular, the total number of blue stragglers found in a given cluster does not seem to correlate with the predicted collision rate, providing indirect support for the binary-evolution model. Yet the radial distributions of blue stragglers in many clusters are bimodal, with a dominant central peak: this has been interpreted as an indication that collisions do dominate blue straggler production, at least in the high-density cluster cores. Here we report that there is a clear, but sublinear, correlation between the number of blue stragglers found in a cluster core and the total stellar mass contained within it. From this we conclude that most blue stragglers, even those found in cluster cores, come from binary systems. The parent binaries, however, may themselves have been affected by dynamical encounters. This may be the key to reconciling all of the seemingly conflicting results found to date.

description: We present a detailed analysis of predicted galaxy-galaxy merger fractions and rates in the Millennium simulation and compare these with the most up to date observations of the same quantities up to z~3. We carry out our analysis by considering the predicted merger history in the Millennium simulation within a given time interval, as a function of stellar mass. This method, as opposed to pair fraction counts, considers mergers that have already taken place, and allows a more direct comparison with the observed rates and fractions measured with the concentration-asymmetry-clumpiness (CAS) method. We examine the evolution of the predicted merger fraction and rate in the Millennium simulation for galaxies with stellar masses M_* ~ 10^9 - 10^12 M_sun. We find that the predicted merger rates and fractions match the observations well for galaxies with M_* > 10^11 M_sun at z<2, while significant discrepancies occur at lower stellar masses, and at z>2 for M_* > 10^11 M_sun systems. At z>2 the simulations underpredict the observed merger fractions by a factor of 4-10. The shape of the predicted merger fraction and rate evolutions are similar to the observations up to z~2, and peak at 1 10^11 M_sun. We discuss possible reasons for these discrepancies, and compare different realisations of the Millennium simulation to understand the effect of varying the physical implementation of feedback. We conclude that the comparison is potentially affected by a number of issues, including uncertainties in interpreting the observations and simulations in terms of the assumed merger mass ratios and merger time-scales.

description: The Companies and Allied Matters Act, 2020i came with innovations aimed at opening up the Nigerian corporate space, boost the Federal Government’s Economic Recovery and Growth Plan with a view to launching Nigeria into top 70 economies by 2023. One of such provisions is s. 303 which is an improvement on s. 277 of CAMA 2004. The section regulates self-dealing by directors. This paper set out to discover what differentiates s. 303 from s. 277 of CAMA 2004 and if it could achieve the envisaged utopian ambition within existing regulatory and inhibiting factors which contributed to the abysmal performance of s. 277. The paper is non empirical, library based and adopted a doctrinal approach. The paper exposed normative and other factors which impeded the success of s. 277 thereby rendering the system vulnerable to directors’ Machiavellian manipulations. The paper found ineffective regulatory systems, archaic justice delivery system which snails justice dispensation and lack of deterring sanctions as some of the factors which impeded the success of s. 277. It concluded that these factors still exist in Nigeria and are likely to stymie s. 303 thereby hindering its effectiveness. The paper therefore prescribed short prison terms, restitutive penalties and the need to grant financial autonomy to the Nigerian judiciary to enhance modernisation of courts as a way out of the present quagmire.

description: Crab cavities have been proposed for a wide number of accelerators and interest in crab cavities has recently increased after the successful operation of a pair of crab cavities in KEK-B. In particular crab cavities are required for both the ILC and CLIC linear colliders for bunch alignment. Consideration of bunch structure and size constraints favour a 3.9 GHz superconducting, multi-cell cavity as the solution for ILC, whilst bunch structure and beam-loading considerations suggest an X-band copper travelling wave structure for CLIC. These two cavity solutions are very different in design but share complex design issues. Phase stabilisation, beam loading, wakefields and mode damping are fundamental issues for these crab cavities. Requirements and potential design solutions will be discussed for both colliders.

Working on the Scottish Archaeological Research Framework (ScARF) pt 3
Creators: name: Sanders, Jeff
Publisher: name: Archaeology Data Service
Year: 2011

description: This resource is a single blog post created as part of the Day of Archaeology initiative. The Day of Archaeology project aimed to provide a window into the daily lives of archaeologists from all over the world. The project asked people working, studying or volunteering in the archaeological world to participate in a 'Day of Archaeology' each year by recording their day and sharing it through text, images or video on the Day of Archaeology blog.
The project asked anyone with a personal, professional or voluntary interest in archaeology to get involved, and help highlight the reasons why archaeology is vital to protect the past and inform our futures. The resulting Day of Archaeology project archive demonstrates the wide variety of work the archaeological profession undertakes day-to-day across the globe, and helps to raise public awareness of the relevance and importance of archaeology to the modern world.
The first ever Day of Archaeology was held in 2011 and, since then, the project had thousands of archaeologists take part in the event, from those working in the field through to specialists working in laboratories and behind computers. The last Day of Archaeology was on Friday 28th July 2017.

description: High-resolution photoemission spectroscopy and realistic ab-initio calculations have been employed to analyze the onset and progression of d-sp hybridization in Fe impurities deposited on alkali metal films. The interplay between delocalization, mediated by the free-electron environment, and Coulomb interaction among d-electrons gives rise to complex electronic configurations. The multiplet structure of a single Fe atom evolves and gradually dissolves into a quasiparticle peak near the Fermi level with increasing the host electron density. The effective multi-orbital impurity problem within the exact diagonalization scheme describes the whole range of hybridizations.

Tropical exports and economic growth : the case of Ceylon
Creators: name: Abeynayake, Chrishanthi
Publisher: name: University of British Columbia

description: Ceylon has experienced a long period of export growth. Although export expansion led to a rise in G.N.P., there is not much indication that export expansion alone was sufficient to cause a sustained and general increase of per capita incomes. Per capita G.N.P. is estimated to have risen at the rate of 1.1 per cent per annum between 1926 and 1945. Trade also had only a limited effect in diversifying Ceylon's economic structure. Growth appeared to be confined to exports and immediately ancillary services. The late 1940's ushered in a new era with the grant of Independence. Growth in per capita G.N.P. accelerated from 1947 to 4.0 per cent per annum and was accompanied by an expansion of domestic agriculture and industry despite the fact that Ceylon also experienced a population boom since 1947. Why did exports fail to operate as a leading sector in the particular case of Ceylon? The problem is approached by an examination of the following relevant factors: The historical background and the opening up of the economy to trade comprising an investigation of the impact of coffee plantations; some aspects of the production functions of export industries relevant to determining the magnitude of foreign exchange earnings, share of locally retained income; the scope for backward, forward and final demand linkages; the causes for inadequate response as well as the factors responsible for the accleration in growth in later years. A theory which states that the nature of the production functions of export industries has a direct bearing on the extent to which the stimulus from exports leads to the development of related sectors would be relevant to almost any underdeveloped export economy in which foreign trade plays a significant role. Other factors, however, such as the shortage of capital combined with the lack of credit facilities, the free availability of imports and inadequate infant industry protection, a land-based value system and the negative role of the government vis-a-vis domestic agriculture and industry seem to have been major impediments to diversification around the export base. Acceleration in economic growth and a greater degree of diversification in the economic structure of Ceylon in the post-Independence period appear to be connected with government policy, initiative and assistance.
Ducks on the torus: existence and uniqueness

description: We show that there exist generic slow-fast systems with only one (time-scaling) parameter on the two-torus, which have canard cycles for arbitrary small values of this parameter. This is in drastic contrast with the planar case, where canards usually occur in two-parametric families. Here we treat systems with a convex slow curve. In this case there is a set of parameter values accumulating to zero for which the system has exactly one attracting and one repelling canard cycle. The basin of the attracting cycle is almost the whole torus.
