White2 : the development of modernism in Australia (1850-1930) and the significant contribution made by women through domestic decoration and design
Creators: name: Broad, E
Publisher: name: University Of Tasmania
Year: 2023

description: My research addresses the development of Modernism in Australia within the period c.1850 - 1930. The project focuses on the contribution made to this development by women through domestic decoration; and investigates the creative input of domestic needlework. The research examines historical issues which were paramount to the emergence of Modernism led by women; defines those issues as they relate to Australian women artists; and discusses this Australian version of Modernism against a backdrop of European Modernism. The visual component of my work explores through the medium of textile the irony of the relationship between yesterday's handmade needlework ethos and contemporary textile design and machine manufacturing processes.

description: We currently perform calculations with an improved staggered fermion action (p4fat3). We use a strange quark mass that has been tuned to its physical value and light quarks of mass m_s/20 on lattices of size 32^3x8. This corresponds to an almost physical light quark mass. We present first results on the low temperature part of the equation of state of QCD. Through comparison with the preliminary hotQCD results on the N_tau=8 equation of state, which have been obtained with twice heavier light quark masses, we can quantify the quark mass dependence of the equation of state in the low temperature regime. We also comment on the quark mass dependence of the equation of state at high temperature.

The effects of massed and distributed practice upon motor performance and learning in groups of different initial ability
Creators: name: Pouliot, Jacques
Publisher: name: University of British Columbia
Year: 2011

description: An investigation was conducted to determine if the performance and learning of a pursuit rotor skill was a function of practice schedule and initial ability level. Two groups of 30 subjects each were given two consecutive days of practice, with 22 and 20 trials respectively, on the pursuit rotor under different schedules of practice. The performance score of the massed practice group (30 secs. work, 5 secs. rest) was found to be significantly lower than that of the distributed practice group (30 secs. work, 30 secs. rest) on the first day of practice. However, after 24 hours of interpolated rest, both groups were statistically equal in terms of the amount learned. A further analysis of the first day's performance scores of the 10 high initial ability and the 10 low initial ability subjects from each of the two main groups found no differential effect of practice schedule attributable to initial ability level. Further, there was no significant ability levels by practice schedules interaction for learning. However, reminiscence was found to be related to ability level as low ability subjects reminisced significantly more than high ability subjects.

description: We examine a situation that $n$ eavesdroppers attack the Bennett-Brassard cryptographic protocol via their own optimal and symmetric strategies. Information gain and mutual information with sender for each eavesdropper are explicitly derived. The receiver's error rate for the case of arbitrary $n$ eavesdroppers can be derived using a recursive relation. Although first eavesdropper can get mutual information without disturbance arising due to other eavesdroppers, subsequent eavesdropping generally increases the receiver's error rate. Other eavesdroppers cannot gain information on the input signal sufficiently. As a result, the information each eavesdropper gains becomes less than optimal one.

description: The Hartree-Fock approximation to the many-fermion problem can break exact symmetries, and in some cases by changing a parameter in the interaction one can drive the Hartree-Fock minimum from a symmetry-breaking state to a symmetry-conserving state (also referred to as a ``phase transition'' in the literature). The order of the transition is important when one applies the random phase approximation (RPA) to the of the Hartree-Fock wavefunction: if first order, RPA is stable through the transition, but if second-order, then the RPA amplitudes become large and lead to unphysical results. The latter is known as ``collapse'' of the RPA. While the difference between first- and second-order transitions in the RPA was first pointed out by Thouless, we present for the first time non-trivial examples of both first- and second-order transitions in a uniform model, the interacting shell-model, where we can compare to exact numerical results.

description: We study general two-dimensional sigma-models which do not possess manifest Lorentz invariance. We show how demanding that Lorentz invariance is recovered as an emergent on-shell symmetry constrains these sigma-models. The resulting actions have an underlying group-theoretic structure and resemble Poisson-Lie T-duality invariant actions. We consider the one-loop renormalization of these models and show that the quantum Lorentz anomaly is absent. We calculate the running of the couplings in general and show, with certain non-trivial examples, that this agrees with that of the T-dual models obtained classically from the duality invariant action. Hence, in these cases solving constraints before and after quantization are commuting operations.

description: Menopause is currently portrayed in the medical literature as a pathological 11 process resulting from "hormone deficiency." However, feminist writers contend that the climacteric is part of the normal female aging process and oppose the medicalization of menopause and the consequent inevitable hormone replacement therapy (HR T) promoted by the hegemonic medical and pharmaceutical industries. This paper explores the historical development of these two paradigms of menopause and their manifestations in samples of three classes of contemporary literature on the subject: gynecological textbooks, popular advice books written by physicians, and women's accounts. Five major themes are investigated using quantitative and qualitative content analysis to assess the extent of agreement of the three samples of literature with the contradictory biomedical and feminist models. Gynecological texts, as expected, fit most closely the negative biomedical paradigm. Popular advice books by physicians also agree strongly that menopause requires medical "management" and treatment with hormones. They are a powerful tool for persuading women to comply with increasing medical and social pressure to take HRT. Women's accounts of the climacteric reveal a much wider range of experiences and reactions to the mid-life passage. Many women also question the safety of HRT and recommend a variety of alternative treatments. Since the pathological biomedical ideology dominates the popular media. it is vitally important for women seeking information on the menopause to read widely on the subject and especially to examine works by other women. It is also essential that women continue to give voice to their own experiences and definitions of the climacteric in order to challenge the stigmatization of menopause by the hegemonic biomedical model.

description: We present measurements of the resistivity and the upper critical field H_c2 of Nd(O_0.7F_0.3)FeAs single crystals in strong DC and pulsed magnetic fields up to 45 T and 60 T, respectively. We found that the field scale of H_c2 is comparable to ~100 T of high T_c cuprates. H_c2(T) parallel to the c-axis exhibits a pronounced upward curvature similar to what was extracted from earlier measurements on polycrystalline samples. Thus this behavior is indeed an intrinsic feature of oxypnictides, rather than manifestation of vortex lattice melting or granularity. The orientational dependence of H_c2 shows deviations from the one-band Ginzburg-Landau scaling. The mass anisotropy decreases as T decreases, from 9.2 at 44K to 5 at 34K. Spin dependent magnetoresistance and nonlinearities in the Hall coefficient suggest contribution to the conductivity from electron-electron interactions modified by disorder reminiscent that of diluted magnetic semiconductors. The Ohmic resistivity measured below T_c but above the irreversibility field exhibits a clear Arrhenius thermally activated behavior over 4-5 decades. The activation energy has very different field dependencies for H||ab and H\perp ab. We discuss to what extent different pairing scenarios can manifest themselves in the observed behavior of H_{c2}, using the two-band model of superconductivity. The results indicate the importance of paramagnetic effects on H_c2(T),which may significantly reduce H_c2(0) as compared toH_c2(0)~200-300 T based on extrapolations of H_c2(T) near T_c down to low temperatures.

Effects of interference in the dynamics of spin-1/2 transverse XY Chain driven periodically through quantum critical points

description: We study the effects of interference on the quenching dynamics of a one-dimensional spin 1/2 $XY$ model in the presence of a transverse field ($h(t)$) which varies sinusoidally with time as $h = h_0\cos{ωt}$, with $|t| \leq t_f = π/ω$. We also consider the situation where the magnetic field consists of an oscillatory as well as a linearly varying component, i.e., $h(t) = h_0\cos{ωt} + t/τ$. Our purpose is to estimate the defect density and the local entropy density in the final state if the system is initially prepared in its ground state. For a single crossing through the quantum critical point with $h = h_0\cos{ωt}$, the density of defects in the final state is calculated by mapping the dynamics to an equivalent Landau Zener problem by linearizing near the crossing point, and is found to vary as $\sqrtω$ in the limit of small $ω$. On the other hand, the local entropy density is found to attain a maximum as a function of $ω$ near a characteristic scale $ω_0$. Extending to the situation of multiple crossings, we show that the non-trivial interference effects of certain resonance modes solely contribute to the production of defects. Kink density as well as the diagonal entropy density show oscillatory dependence on the number of full cycles of oscillation. Finally, the inclusion of a linear term in the transverse field on top of the oscillatory component, results to a kink density which decreases continuously with $τ$ and $ω$. The entropy density shows monotonous growth with both $τ$ and $ω$, in sharp contrast to the situations studied earlier. We do also propose appropriate scaling relations for the defect density in above situations and compare the results with the numerical results obtained by integrating the Schrodinger equations.

description: We have performed a dynamical coupled-channels analysis of available p(e,e'pi)N data in the region of W < 1.6 GeV and Q^2 < 1.45 (GeV/c)^2. The channels included are gamma^* N, pi N, eta N, and pi pi N which has pi Delta, rho N, and sigma N components. With the hadronic parameters of the model determined in our previous investigations of pi N --> pi N, pi pi N reactions, we have found that the available data in the considered W < 1.6 GeV region can be fitted well by only adjusting the bare gamma^* N --> N^* helicity amplitudes for the lowest N^* states in P33, P11, S11 and D13 partial waves. The sensitivity of the resulting parameters to the amount of data included in the analysis is investigated. The importance of coupled-channels effect on the p(e,e' pi)N cross sections is demonstrated. The meson cloud effects, as required by the unitarity conditions, on the gamma^* N --> N^* form factors are also examined. Necessary future developments, both experimentally and theoretically, are discussed.

description: Massive bosons a reconstructed from generalized biparticle states of massless scalar particles ("zerons") and of massless vector particles (photons). The self-coupling of the zeron field ϭ₀ is described by the Lagrangian density g₀º₀⁴. The self-coupling of the photon field is described by the duality in variant Misner-Wheeler Lagrangian density. Doublet mass spectra are generated if the coupling constants take the appropriate signs. Each such spectrum is fitted to that of an experimentally observed meson doublet having the correct spin and parity. The coupling constants and the cut-offs that are introduced are there by determined uniquely. The coupling constant and the cut-off ⋋ in the zeron model assume the values g₀ = -9.50 and ⋋ = 515 n.u. in the photon model, both scalar and pseudo scalar particles are constructed. The respective cut-offs and coupling constants are ⋋ ₍₊₎ = 729 n.u. , g₊ = 1.67 x 10⁻⁵ n.u. and ⋋ ₍₋₎ = 574 n.u., g₍₋₎ = 3.34 x 10⁻⁵ n.u.

We traced the inductance using microwave reflection measurements on a tuned resonance circuit in which a SCPT was mounted in parallel to a $ \sim 200$ pH strip line inductance. When the inverse of the Josephson inductance, determined on the charge-phase bias plane for a SCPT with a Josephson to Coulomb energy ratio of $E_J/E_C =1.75$, is integrated over the phase, we obtain a current-phase relation, which is strongly non-sinusoidal near the charge degeneracy point.

Publisher: name: Old Dominion University Libraries

description: Myths are metaphors. They are stories, sometimes handed down through hundreds of years, which help put man or a culture in accord with nature, to reconcile mankind to the harsh realities of life. Society's heroes, acting through the archetypal hero monomyth, serve as the personification of a culture's mythology. Through the hero, a society may reconcile with nature and those external forces which influence our lives.

This paper examines the historical development of the hero myth, the archetypal hero role that Robert E. Lee filled for the Southern people during the American civil War and the role that photography played in forming that image of Lee, the development of photography in America from 1839 through the 1860s, the role of Southern photographers during the war, and the apotheosis and image of Lee.

description: We present a new mass estimate for the Hercules dwarf spheroidal galaxy (dSph), based on the revised velocity dispersion obtained by Aden et al. (2009, arXiv:0908.3489). The removal of a significant foreground contamination using newly acquired Stromgren photometry has resulted in a reduced velocity dispersion. Using this new velocity dispersion of 3.72 +/- 0.91 km/s, we find a mass of M_300=1.9^{+1.1}_{-0.8} 10^6 M_sun within the central 300 pc, which is also the half-light radius, and a mass of M_433=3.7_{-1.6}^{+2.2} 10^6 M_sun within the reach of our data to 433 pc, significantly lower than previous estimates. We derive an overall mass-to-light ratio of M_433/L=103^{+83}_{-48} M_sun/L_sun. Our mass estimate calls into question recent claims of a common mass scale for dSph galaxies. Additionally, we find tentative evidence for a velocity gradient in our kinematic data of 16 +/- 3 km/s/kpc, and evidence of an asymmetric extension in the light distribution at about 0.5 kpc. We explore the possibility that these features are due to tidal interactions with the Milky Way. We show that there is a self-consistent model in which Hercules has an assumed tidal radius of r_t = 485 pc, an orbital pericentre of r_p = 18.5 +/- 5 kpc, and a mass within r_t of M_{tid,r_t}=5.2 +/- 2.7 10^6 M_sun. Proper motions are required to test this model. Although we cannot exclude models in which Hercules contains no dark matter, we argue that Hercules is more likely to be a dark matter dominated system which is currently experiencing some tidal disturbance of its outer parts.

Chemical analysis of sediments using X-Ray fluorescence on-board an Autonomous Underwater Vehicle
Creators: name: Breen, JP
Publisher: name: University Of Tasmania
Year: 2023

description: Advances in robotics have led to the development of autonomous platforms capable of exploring regions that are inaccessible for humans. These regions range from extra-terrestrial surfaces, such as Mars and Titan, to the bottom of our oceans. In addition to robotics there have also been advances in sensor technologies in areas such as power consumption, size, weight, and communications. The combination of field robotics with novel sensing capabilities provides exciting science opportunities. Autonomous measurement of phenomena present in the environment offers an alternative to expensive, time-consuming manual measurements. This thesis investigates the novel use of a miniaturised X-Ray Fluorescence (XRF) spectrometer sensor system as part of the scientific payload on an Autonomous Underwater Vehicle (AUV). This will allow the automated in situ semi-quantitative analysis of heavy metal contamination present in marine sediments. Heavy metal contamination of sediments is particularly important because of its potential impact on associated ecosystems and human health. To achieve this capability the XRF system has been integrated with the AUV using a custom housing that enables the sensor to be operated safely underwater. A landing behaviour has been developed for the AUV that enables the vehicle to land on the seabed, without signicantly disturbing the sediment layer, and to then remain in a stationary position for the duration of the measurement. Automated data analysis using genetic algorithms was performed on the XRF data on-board the vehicle. This would enable the AUV control system to make informed decisions based on the results of measurements facilitating adaptive sampling strategies. A total of 21 in situ measurements have been performed in the Derwent estuary region, located in south-east Tasmania, Australia. The results show significantly higher relative heavy metal concentrations in areas of industrial activity. This demonstrates the developed system can perform in situ measurements that can be used to observe spatial variations in heavy metal contamination. The resulting data from these measurements can guide further comprehensive environmental monitoring missions by supporting site selection or assisting with the remediation of contaminated sediments. The research contribution presented in this thesis has been the development of the capability to autonomously and intelligently perform in situ measurements and data analysis of marine sediments using an AUV equipped with a miniaturised XRF spectrometer. The next stage of this research will aim to increase the scientific return of measurement missions by the realtime inclusion of scientific sensor data in decision-making processes to enable adaptive sampling.
Higher Winding Strings and Confined Monopoles in N=2 SQCD

description: We consider composite string solutions in N=2 SQCD with the gauge group U(N), the Fayet--Iliopoulos term ξ\neq 0 and N (s)quark flavors. These bulk theories support non-Abelian strings and confined monopoles identified with kinks in the two-dimensional world-sheet theory. Similar and more complicated kinks (corresponding to composite confined monopoles) must exist in the world-sheet theories on composite strings. In a bid to detect them we analyze the Hanany--Tong (HT) model, focusing on a particular example of N=2. Unequal quark mass terms in the bulk theory result in the twisted masses in the N=(2,2) HT model. For spatially coinciding 2-strings, we find three distinct minima of potential energy, corresponding to three different 2-strings. Then we find BPS-saturated kinks interpolating between each pair of vacua. Two kinks can be called elementary. They emanate one unit of the magnetic flux and have the same mass as the conventional 't Hooft--Polyakov monopole on the Coulomb branch of the bulk theory (ξ=0). The third kink represents a composite bimonopole, with twice the minimal magnetic flux. Its mass is twice the mass of the elementary confined monopole. We find instantons in the HT model, and discuss quantum effects in composite strings at strong coupling. In addition, we study the renormalization group flow in this model.

description: In this article we present a study of the electrical resistivity of Yb(Rh-xIrx)2Si2, x=0.06, under high pressure and in magnetic field. Ir substitution is expanding the unit cell and leads to a suppression of the antiferromagnetic transition temperature to zero, where eventually a quantum critical point (QCP) exists. We applied hydrostatic pressure to reverse the effect of substitution. Our results indicate that Yb(Rh0.94Ir0.06)2Si2 is situated in the immediate proximity to a volume controlled QCP, but still on the magnetically ordered side of the phase diagram. The temperature - pressure phase diagram of Yb(Rh0.94Ir0.06)2Si2 resembles that of the pure compound. Substitution acts mainly as chemical pressure. Disorder introduced by substitution has only minor effects.

description: The nature of the superconducting state in the recently discovered Fe-based superconductors1-3 is the subject of intense scrutiny. Neutron scattering investigations have already elucidated a strong correlation between magnetism and superconductivity in the form of a spin resonance in the magnetic excitation spectrum4-7. A central unanswered question concerns the nature of the normal state spin fluctuations which may be responsible for the pairing mechanism. Here we show inelastic neutron scattering measurements of Fe1.04Te0.73Se0.27, not superconducting in bulk, and FeTe0.51Se0.49, a bulk superconductor. These measurements demonstrate that the spin fluctuation spectrum is dominated by two-dimensional incommensurate excitations near the (1/2,1/2) (square lattice (pi,0)) wavevector, the wavevector of interest in other Fe-based superconductors, that extend to energies at least as high as 300 meV. Most importantly, the spin excitations in Fe1+yTe1-xSex exhibit four-fold symmetry about the (1,0) (square lattice (pi,pi)) wavevector and are described by the identical wavevector as the normal state spin excitations in the high-TC cuprates8-12 demonstrating a commonality between the magnetism in these classes of materials which perhaps extends to a common origin for superconductivity.

description: Watch video of this presentation at https://youtu.be/kCZRauYfqvg. Human languages develop over time a set of cultural associations. For example, during the early and mid-twentieth century, the Spanish language in the United States was seen both as a European high literary language and as a language associated with femininity and racial mixture. In my dissertation work, I documented how US modernist poets who translated from Spanish used or resisted those associations as they intervened in controversies over race and style in twentieth century poetics. Coding languages, too, can take on gendered and raced cultural associations. This talk explores the possibility of an analogous set of dynamics in the history of coding languages, exploring their changing cultural associations as languages and how those cultural associations were expressed in changing coding styles or conventions. It draws on the work of Vikram Chandra (Geek Sublime) and other writers exploring the cultural meanings and stylistic associations of computer code.

description: Angular momentum transport within young massive protoplanetary discs may be dominated by self-gravity at radii where the disk is too weakly ionized to allow the development of the magneto-rotational instability. We use time-dependent one-dimensional disc models, based on a local cooling time calculation of the efficiency of transport, to study the radial structure and stability (against fragmentation) of protoplanetary discs in which self-gravity is the sole transport mechanism. We find that self-gravitating discs rapidly attain a quasi-steady state in which the surface density in the inner disc is high and the strength of turbulence very low (alpha ~ 10^{-3} or less inside 5 au). Temperatures high enough to form crystalline silicates may extend out to several au at early times within these discs. None of our discs spontaneously develop regions that would be unambiguously unstable to fragmentation into substellar objects, though the outer regions (beyond 20 au) of the most massive discs are close enough to the threshold that fragmentation cannot be ruled out. We discuss how the mass accretion rates through such discs may vary with disc mass and with mass of the central star, and note that a determination of the \dot{M}-M_* relation for very young systems may allow a test of the model.

John Morgan: colonial middle class recruit

description: During the 1840's the clamour of dissatisfaction from the free settlers in the colonies of Australia caused many an eyebrow to lift at Westminster. It was hard to appreciate how British people a few years removed from their homeland could get themselves in such a turmoil when the issues seen from London seemed so clear cut. When it was more or less decided to give the colonists the independent institutions they seemed to want so much, Earl Grey, Secretary of State for the Colonies, requested Lieutenant Governor Denison of Van Diemen's Land to send home a description of the sort of people these colonists really were.

The First VLBI Detection of an Ultracool Dwarf: Implications for the Detectability of Sub-stellar Companions

description: We present milliarcsecond-resolution radio very long baseline interferometry (VLBI) observations of the ultracool dwarfs TVLM513-46546 (M8.5) and 2MASS J00361617+1821104 (L3.5) in an attempt to detect sub-stellar companions via direct imaging or reflex motion. Both objects are known radio emitters with strong evidence for periodic emission on timescales of about 2 and 3 hours, respectively. Using the inner seven VLBA antennas, we detect unresolved emission from TVLM513-46546 on a scale of 2.5 mas (~50 stellar radii), leading to a direct limit on the radio emission brightness temperature of T_B > 4x10^5 K. However, with the higher spatial resolution afforded by the full VLBA we find that the source appears to be marginally and asymmetrically resolved at a low S/N ratio, possibly indicating that TVLM513-46546 is a binary with a projected separation of ~1 mas (~20 stellar radii). Using the 7-hour baseline of our observation we find no astrometric shift in the position of TVLM513-46546, with a 3-sigma limit of about 0.6 mas. This is about 3 times larger than expected for an equal mass companion with a few-hour orbital period. Future monitoring of its position on a range of timescales will provide the required astrometric sensitivity to detect a planetary companion with a mass of ~10 M_J in a >15 d (>0.06 AU) orbit, or with a mass of ~2 M_J in an orbit of >0.5 yr (>0.3 AU).

description: The study of high pressure (2 GPa) synthesized MgB2-based materials allows us to conclude that higher borides (with near MgB12 stoichiometry) and oxygen-enriched Mg-B-O inclusions can be pinning centers in nanostructural magnesium diboride matrix (with average grain sizes of 15-37 nm). It has been established that additions of Ti or SiC as well as manufacturing temperature can affect the size, amount and distribution of these inclusions in the material structure and thus, influence critical current density. The superconducting behavior of materials with near MgB12 stoichiometry of matrix is discussed.

description: O presente trabalho tem como escopo a análise de como o Estado é responsabilizado por danos oriundos de suas omissões. Para tanto, procedeu-se, inicialmente, ao estudo da responsabilidade civil do Estado desde a sua origem, analisando sua evolução tanto dentro do contexto geral como dentro do ordenamento pátrio. Após, analisou-se o preceito constitucional esculpido no art. 37 da Constituição Federal de 1988, bem como os relevantes pontos dele derivados. Por derradeiro, abordou-se a responsabilidade por omissão do Estado, de modo a verificar, sob o atual prisma doutrinário e, especialmente, jurisprudencial, qual a teoria que melhor se adequa ao Estado Democrático de Direito brasileiro – objetiva ou subjetiva.

description: We study thermodynamic properties and the electrical conductivity of dense hydrogen and deuterium using three methods: classical reactive Monte Carlo (REMC), direct path integral Monte Carlo (PIMC) and a quantum dynamics method in the Wigner representation of quantum mechanics. We report the calculation of the deuterium compression quasi-isentrope in good agreement with experiments. We also solve the Wigner-Liouville equation of dense degenerate hydrogen calculating the initial equilibrium state by the PIMC method. The obtained particle trajectories determine the momentum-momentum correlation functions and the electrical conductivity and are compared with available theories and simulations.
Learning and teaching science: linking cognitive development and curriculum design
Creators: name: Cavell, S
Publisher: name: University Of Tasmania

description: It is well documented that many school students come to science class with a variety of 'alternative conceptions' and that these remain largely untouched by teaching. This thesis describes research work that determined, analysed, and developed strategies to promote students' understanding of two physics topics. This research looked at the learning and teaching of science from both a cognitive and a curriculum perspective. The principal aims of this research were to investigate students' understanding of 'light' and of 'sound' in terms of theoretical cognitive models, to design and implement instructional units on these topics that would facilitate the development of a scientific understanding, and to monitor changes in the levels of understanding, over the period of the investigation, in terms of the theoretical models. 'Light and seeing' was the focus of the preliminary investigation or pilot study; 'sound and hearing' was the main focus of the research. There were two main components of this research. The first was a psychological component that utilised a theoretical framework, based on the SOLO Taxonomy of cognitive functioning, for students' developing understanding of the concept. In the study of 'light and seeing', the theoretical model of Collis, Jones, Sprod, Watson, and Fraser (1998) was used. In the study of 'sound and hearing', the theoretical model was formulated by the researcher. The second component was a curriculum component in which constructivist Teaching Units for both topics were developed, structured in such a way as to follow the pathways postulated in the theoretical models of cognitive development. It was the linking of cognitive developmental theory and curriculum design in science education that set the present research apart from the work of other researchers. Conclusions were drawn from this research as to the usefulness of the theoretical models of cognitive development and of the Teaching Units closely aligned with the theoretical models. These can be applied both to teaching and to curriculum development. They have the potential to provide teachers with the tools to improve, not only their teaching, but also the understanding of their students, in the concept areas discussed in this thesis as well as in a wide variety of other science concept areas. The potential also exists for the use of the theoretical models for assessment purposes, and to provide profiles of student achievement.
title: The Carter Administrative Elite: A Background Analysis

description: This study is an inter-disciplinary analysis of the backgrounds of the Carter administrative elite. Various theories of political science, public administration, and ethics are presented in relation to Jimmy Carter's appointees. A background composite is presented of the elites' education, career before government service, age, sex, and geographic region of birth and socialization. Information about the elites was obtained from biographical listings, and was stored and processed by an electronic data processing system.

The Carter administrative elite has included persons who have been named to positions that do not maximize their experiences and qualifications in the most appropriate manner. This administration has included engineers in high-level administrative positions, which indicates a new trend in elite recruitment. The selection of officials Jimmy Carter has made are discussed in light of the ethical theories of Jeremy Bentham and John Rawls.

description: We study flexible polymer macromolecules in a crowded (porous) environment, modelling them as self-attracting self-avoiding walks (SASAW) on site-diluted percolative lattices in space dimensions d=2, 3. The influence of stretching force on the polymer folding and properties of globule-coil transitions are analyzed. Applying the pruned-enriched Rosenbluth chain-growth method (PERM), we estimate the transition temperature T_Θ between collapsed and extended polymer configurations and construct the phase diagrams of the globule-coil coexistence when varying temperature and stretching force. The transition to a completely stretched state, caused by applying force, is discussed as well.

description: The veterinary profession continues to make greater use of production databases in serving the dairy industry. Increasingly sophisticated database management systems allow producers and practitioners to consider the biological, statistical, and economic implications of management interventions. Frequency distributions and simple descriptive statistics can be very helpful in understanding patterns that underlie commonly used measures of dairy herd productivity. Once underlying patterns are understood, statistics can be used to set feasible production targets and confidence intervals to accommodate the variability inherent in biology. This is particularly appropriate for smaller herds or when one wishes to analyze performance over short time periods. Confidence intervals and interference levels can be adjusted to lessen the chances of erroneous conclusions being drawn when sample sizes are small. Consequences of drawing the wrong conclusions are implementing changes when no intervention is warranted, or failing to act quickly enough in response to falling productivity. Practicing veterinarians can apply these simple-to-use practical techniques which help avoid the trap of confusing normal variation with real changes in productivity.
