description: In this paper, interaction between Brij97 and NaDC in mixed micelles was studied by surface tension method. Phase behavior for Brij97/NaDC/IPM/H2O system was investigated at the desire molar ratio of αNaDC = 0.42 and the human body temperature of 37 °C. Hexagonal and cubic liquid crystal were found in this system analyzed by small angle x-ray scattering (SAXS). some factors were changed to affect the rheological properties of liquid crystal. Rheological investigations showed: The higher content of water and lower experimental temperature favored the greater values of shear viscosity and viscoelastic modulus; The sample was closer to the plastic fluid and was more likely to recover from disturbed state to equilibrium state at lower ratio of NaDC; The curcumin and TP can influence the shear viscosity, viscoelastic properties and phase transition temperature, even change the structure of liquid crystal. This supplies a way to adjust rheological properties, structure and even phase transition by altering those factors.

description: Exotic compact objects may resemble black holes very closely while remaining horizonless. They may be distinguished from black holes because they effectively give rise to a resonant cavity for the propagation of low frequency gravity waves. In a Green's function approach, the resonance structure appears in a transfer function. The transfer function in turn is modulated by an initial-condition-dependent source integral to obtain the observed spectrum. We find that the source integral displays universal factors that tend to enhance low and negative frequencies, and this increases the complexity of the waveforms in the time domain. These waveforms also display a significant sensitivity to initial conditions. For these reasons a standard matched-filter search strategy is difficult. In contrast, the sharp and evenly spaced resonance spectrum presents a much more robust signal to target. It persists even in the absence of simple echoes. We also describe an additional two-component structure of this resonance pattern.

description: We describe how the presence of the antisymmetric tensor (torsion) on the world sheet action of string theory renders the size of the target space a gauge non invariant quantity. This generalizes the R 1/R symmetry in which momenta and windings are exchanged, to the whole O(d,d,Z). The crucial point is that, with a transformation, it is possible always to have all of the lowest eigenvalues of the Hamiltonian to be momentum modes. We interpret this in the framework of noncommutative geometry, in which algebras take the place of point spaces, and of the spectral action principle for which the eigenvalues of the Dirac operator are the fundamental objects, out of which the theory is constructed. A quantum observer, in the presence of many low energy eigenvalues of the Dirac operator (and hence of the Hamiltonian) will always interpreted the target space of the string theory as effectively uncompactified.

description: This thesis examines the contribution that changes in young people’s agency, aspirations and decision-making during participation in social enterprises make in improving engagement and outcomes in employment, education and training. The focus is contextualised within the growing number of young people who are marginalised by not engaging in employment, education and training in Australia and the majority of countries in the Organisation for Economic Co-operation and Development (2012). Consequences of young people’s marginalisation are experienced at the personal, community and Government levels and include long-term marginalisation and heavy social and financial costs. The focus of this study is social enterprises that operate as intermediate labour market interventions with a social purpose. These enterprises address the vocational and non-vocational barriers of marginalised groups in an effort to assist them to obtain employment, education and training outcomes. While the literature on social enterprises is increasing, a gap persists regarding the possible changes in cognitive-motivational variables such as agency, aspirations and decision-making processes and their roles in promoting positive outcomes. In particular, the lack of research and theorisation addressing the predictive potential of change in such cognitive-motivational variables as young people participate in social enterprises has restricted evidence-based service delivery to capitalise on any such relation.

description: FAMILY VARUNIDAE H. MILNE EDWARDS, 1853   Remarks: The varunids were formerly treated as a subfamily of the Grapsidae, most of which are commonly called ‘shore crabs’ (Williams et al., 1989; McLaughlin et al., 2005). Recognition of the Varunidae as a separate family follows the classification of Martin & Davis (2001) and papers cited therein. The only genus of the family Varunidae known from vents, Xenograpsus (see below), is probably deserving of its own family (P. Ng, pers. comm.) based on larval morphology and other characters; if so this would leave the varunids without known vent representatives.

description: Quantum Monte Carlo (QMC) methods are the gold standard for studying equilibrium properties of quantum many-body systems -- their phase transitions, ground and thermal state properties. However, in many interesting situations QMC methods are faced with a sign problem, causing the severe limitation of an exponential increase in the sampling complexity and hence the run-time of the QMC algorithm. In this work, we develop a systematic, generally applicable, and practically feasible methodology for easing the sign problem by efficiently computable basis changes and use it to rigorously assess the sign problem. Our framework introduces measures of non-stoquasticity that -- as we demonstrate analytically and numerically -- at the same time provide a practically relevant and efficiently computable figure of merit for the severity of the sign problem. We show that those measures can practically be brought to a good use to ease the sign problem. To do so, we use geometric algorithms for optimization over the orthogonal group and ease the sign problem of frustrated Heisenberg ladders. Complementing this pragmatic mindset, we prove that easing the sign problem in terms of those measures is in general an NP-complete task for nearest-neighbour Hamiltonians and simple basis choices by a polynomial reduction to the MAXCUT-problem. Intriguingly, easing remains hard even in cases in which we can efficiently assert that no exact solution exists.

description: A well-known result of Kostant gives a description of the G-module structure for the exterior algebra of Lie algebra $\frak g$. We give a generalization of this result for the isotropy representations of symmetric spaces. If $\frak g={\frak g}_0+{\frak g_1}$ is a Z_2-grading of a simple Lie algebra, we explicitly describe a ${\frak g}_0$-module $Spin_0({\frak g}_1)$ such that the exterior algebra of ${\frak g}_1$ is the tensor square of this module times some power of 2. Although $Spin_0({\frak g}_1)$ is usually reducible, we show that a Casimir element for ${\frak g}_0$ always acts scalarly on it. We also a give classification of all orthogonal representations of simple algebraic groups having an exterior algebra of skew-invariants.

description: XENOGRAPSUS TAKEDA & KURATA, 1977
 Remarks: Although referred to occasionally as ‘hydrothermal vent crabs’, crabs of the genus Xenograpsus are clearly related to and derived from nearby grapsoid shore crabs and are thus quite different from the ‘true’ vent crabs of the family Bythograeidae. To our knowledge they are restricted to the shallow volcanic vent habitat and are thus endemic (rather than vagrant) species. To date these two species are the only known obligate shallow-water hydrothermal vent crabs (Jeng, Clark & Ng, 2004a; Jeng, Ng & Ng, 2004b). Larvae have been described for one species (see below). The two described species are known from Japan and Taiwan (below), although a crab of this genus also has been observed (though apparently not yet reported) from off New Zealand (P. Ng, pers. comm.).

description: Amyloid-β (Aβ) oligomers play a central role in the pathogenesis of Alzheimer's disease. Oligomers of different sizes, morphology and structures have been reported in both in vivo and in vitro studies, but there is a general lack of understanding about where to place these oligomers in the overall process of Aβ aggregation and fibrillization. Here, we show that Aβ42 spontaneously forms oligomers with a wide range of sizes in the same sample. These Aβ42 samples contain predominantly oligomers, and they quickly form fibrils upon incubation at 37°C. When fractionated using ultrafiltration filters, the samples enriched with smaller oligomers form fibrils at a faster rate than the samples enriched with larger oligomers, with both a shorter lag time and faster fibril growth rate. This observation is independent of Aβ42 batches and hexafluoroisopropanol treatment. Furthermore, the fibrils formed by the samples enriched with larger oligomers are more readily solubilized by epigallocatchin gallate, a main catechin component of green tea. These results suggest that the fibrils formed by larger oligomers may adopt a different structure from fibrils formed by smaller oligomers, pointing to a link between oligomer heterogeneity and fibril polymorphism.

description: This dissertation explores the social and material arrangements in which the cotton market emerged as an object of social scientific inquiry and liberal government in Egypt during the first three decades of the British occupation (1882-1912). This new figuration of the cotton market did not emerge as the natural unfolding of a universal modernity, economic rationality or the inherent logic of capital. Instead, as this study demonstrates, it was a much more earthly affair. In the wake of financial and ecological crises, the colonial elite allied themselves with economists to embed new technologies of calculation into the Egyptian countryside. In the process, they reconfigured what a market was.

There evolution is governed via (a kind of) a parallel transport in this bundle. Some problems concerning observables are considered. There are derived the equations of motion for the state sections and observables. We show that up to a constant the matrix of the coefficients of the evolution operator (transport) coincides with the matrix of the Hamiltonian of the investigated quantum system.

description: GENUS ACANTHACARIS BATE, 1888
 Remarks: According to Holthuis (1991), the genus Acanthacaris currently contains only two known species, both from the deep sea. Watabe & Miyake (2000) mentioned the presence of ‘ Acanthacaris cf. tenuimana ’ at the Hatama Knoll (Okinawa Trough). If verified as true A. tenuimana Bate, 1888, the find would be well within the known range of this species, which was given by Holthuis (1991) as ‘Indo-West Pacific area (Natal, Mozambique, Madagascar, Laccadive Islands, Japan, Philippines, South China Sea, Indonesia, New Caledonia).’ The other species of the genus, Acanthacaris caeca A. Milne-Edwards, 1881, is restricted to the western Atlantic (Caribbean, Gulf of Mexico and Straits of Florida; Holthuis, 1991). The report by Watabe & Miyake (2000) is the only record of the genus from any vent or seep site.

description: We construct a Chern-Simons action for q-deformed gauge theory which is a simple and straightforward generalization of the usual one. Space-time continues to be an ordinary (commuting) manifold, while the gauge potentials and the field strengths become q-commuting fields. Our approach, which is explicitly carried out for the case of `minimal' deformations, has the advantage of leading naturally to a consistent Hamiltonian structure that has essentially all of the features of the undeformed case. For example, using the new Poisson brackets, the constraints form a closed algebra and generate q-deformed gauge transformations.

description: The interaction with surfactants changes from one carbon nanotube species to the other. We used this to replace non-ionic surfactants by ionic ones. By fine-tuning the replacement conditions, we covered some specific nanotubes with non-ionic surfactants and the others with ionic ones. Addition of salt triggers precipitation of the species suspended by the ionic surfactant; this effectively leads to chiral selective enrichment of a carbon nanotube suspension. We hence produce an (8,4)-enriched suspension by replacing a polyglycerol-based custom amphiphile with the commercial SDBS and salting with NaCl.

description: Recently, intense efforts have been devoted to realizing classical analogues of various topological phases of matter. In this Letter, we explore the intriguing Weyl physics by a simple one-dimensional sonic crystal, in which two extra structural parameters are combined to construct a synthetic three-dimensional space. Based on our underwater ultrasonic experiments, we have not only observed the synthetic Weyl points directly, but also probed the novel reflection phase singularity that connects inherently with the topological robustness of Weyl points. As a smoking gun evidence of the topological states of matter, the presence of nontrivial interface modes has been demonstrated further. All experimental data agree well with our full-wave simulations. As the first realization of topological acoustics in synthetic space, our study exhibits great potential of probing high-dimensional topological phenomena by such easily-fabricated and -detected low-dimension acoustic systems.

description: We propose a new systematic fibre bundle formulation of nonrelativistic quantum mechanics. The new form of the theory is equivalent to the usual one but it is in harmony with the modern trends in theoretical physics and potentially admits new generalizations in different directions. In it a pure state of some quantum system is described by a state section (along paths) of a (Hilbert) fibre bundle. Its evolution is determined through the bundle (analogue of the) Schrödinger equation. Now the dynamical variables and the density operator are described via bundle morphisms (along paths). The mentioned quantities are connected by a number of relations derived in this work. The present first part of this investigation is devoted to the introduction of basic concepts on which the fibre bundle approach to quantum mechanics rests. We show that the evolution of pure quantum-mechanical states can be described as a suitable linear transport along paths, called evolution transport, of the state sections in the Hilbert fibre bundle of states of a considered quantum system.

description: Why do some authoritarian regimes exhibit high levels of corruption, while others produce very little? In this study, I show how corruption is used as a signal of performance and loyalty in autocratic regimes. I find that elites in non-democratic regimes reduce corruption in the face of political competitiveness. I test this theory using extensive micro-level data on the public's experiences with bribery in contemporary Russia. This data set is comprised of over 180,000 responses to public opinion surveys from 2001-2016 in Russia's subnational units. Identification of the causal effect of political competition on corruption is achieved with the use of an exogenously-determined electoral calendar--I show how the scheduled end of a term in office is an exogenous positive shock to political competition for authoritarian leaders in Russian regions, a shock that decreases experienced bribery by over 13% in those years. A wide array of alternative measures including novel search engine data and crime statistics support my conclusions. I also show that governors' tenuous hold on their positions--all the more tenuous when in their final years of a term in office--can be bolstered by additional resources that may be at their disposal. By showing how shocks to political competition drive governors to reduce corruption levels for fear of losing their jobs, but also that those shocks have varying effects for different governors, I illustrate the power of a dissatisfied public and authoritarian formal rules to shape behavior in non-democratic regimes. I also examine the linking assumption between public dissatisfaction and corruption experiences. These findings have implications for our understanding of autocratic politics, corruption, and studies of Russia. I show that corruption in authoritarian regimes is not a byproduct of authoritarianism, nor is it merely a result of low capacity--it is also a means of rule and control for autocrats. Modern authoritarian rulers are more discriminating in their application of petty corruption than is commonly understood. Finally, I employ and extend multilevel regression and poststratification (MRP) to generate descriptive estimates of corruption as experienced by the public with much greater accuracy and precision than has been possible previously.

Descriptive data was collected from 216 eligible factory-working mothers of children aged 6-12 months. Data collected included the Demographic Characteristic Questionnaire and the Breastfeeding in the Workplace Survey. Questions included: awareness of factory breastfeeding-friendly policies, breastfeeding behaviors, pumping in the workplace, social support for breastfeeding behaviors during work. Data were analyzed by descriptive statistics. The majority of mothers (93.1%) intended to breastfeed with 93.1% also reporting shift work. Most of them rated the factory’s support as excellent and very good. The rate of exclusive breastfeeding declined from 76.9% at one month to 46.3% at three months, then sharply dropped to 16.2% at four months and 7.4% at six months. Reasons for breastfeeding discontinuation included: maternal report of insufficient milk (36%), infant sent to live with grandmother in other areas (31%), and returning to work (12%).
 Breastfeeding-friendly policies in factories could improve breastfeeding rates during first three months. However, working mothers may need continued information and resources such as why continued breastfeeding is important, how to maintain sufficient milk supply, on-site child care facilities, and managing family life. Occupational health nurses could provide onsite breastfeeding training and/or intervention programs to improve exclusivity and duration of breastfeeding, instructions on use of breast pumps, and lactation support programs in the workplace, especially for women who work shifts.

description: Located on the island of Murano in the Venetian lagoon, the suburban palace built for the celebrated orator Camillo Trevisan and its lavish decorations were completed in the 1550s by a team of artists that included Alessandro Vittoria, Paolo Veronese, and Battista Zelotti. As only a handful of documents relating to the project have survived, scholars have sifted through the stylistic evidence to propose various attributions for the authorship of the building and its decorations, and many questions remain unresolved. Impeded by the building’s poor state of preservation and the difficulty of accessing this private property, studies have offered only partial readings of the extensive decorative program, much of which has been removed, lost, or destroyed. This investigation will therefore look at the project through a lens provided by written materials of the time, including treatises, commentaries, and published correspondence, and analyze the visual and physical evidence offered by the building itself. Eyewitness accounts and this limited selection of evidence allow us to reconstruct the original appearance of the palace and the function of its gardens, and propose how they allowed the patron Camillo to participate in the culture of suburban villeggiatura that flourished on Murano during the sixteenth century. Finally, some new information on Camillo prompts a recasting of the palace and its iconographic program within the context of the growing Venetian printing industry and the emergence of organizations like the Accademia della Fama to which the patron belonged. This study argues that, as a suburban residence built for an eloquent orator, Palazzo Trevisan and its decorative program were conceived to address an elite audience that engaged in the contemporary discussion of rhetorical structure and oratorical eloquence as models for the invention and reception of architecture, sculpture, painting, poetry, and music.

description: Presence or absence of predators selects for different kind of morphologies. Hence, we expect variation in traits that protect against predators to vary over geographical areas where predators vary in past and present abundance. Abdominal larval spines in dragonfly larvae provide protection against fish predators. We studied geographical variation in larval spine length of the dragonfly Leucorrhinia dubia across Western Europe using a phylogenetic approach. Larvae were raised in a common garden laboratory experiment in the absence of fish predators. Results show that larvae from northern Europe (Sweden and Finland) had significantly longer larval spines compared to larvae from western and central Europe. A phylogeny based on SNP data suggests that short larval spines is the ancestral stage in the localities sampled in this study, and that long spines have evolved in the Fenno-Scandian clade. The role of predators in shaping the morphological differences among the sampled localities is discussed.
DYNAMICS PRECEDING ONSET AND TERMINATION OF ATRIAL FIBRILLATION AND VENTRICULAR TACHYCARDIA

description: The dynamics before transition from a normal heart rhythm into, and out of Atrial Fibrillation and Ventricular Tachycardia, two common cardiac arrhythmias, is still unknown. Using ECG data, we established that the transition for both onset and termination of the two arrhythmias is preceded by a dynamical phenomenon known as ‘flickering’. Flickering could be used as part of an early warning or screening system, and guide the development of new pharmaceuticals and control methods for prevention and intervention of the arrhythmias. The methods developed in this thesis may also be adapted for study of other chronic episodic diseases.

Calming New York: An Examination of Neighborhood Slow Zones

description: Road traffic crashes are a leading cause of death and injury worldwide and in the US. In New York City, there are about 60,000 annual traffic casualties, including over 200 deaths. Area-wide traffic calming can improve traffic safety, pedestrian and cyclist comfort, and quality of life in neighborhoods (Elvik, 2009).  This dissertation examines an area-wide traffic calming program, New York City’s “Neighborhood Slow Zones” (NSZs), in terms of environmental justice, traffic safety, and street design.
      The dissertation consists of three distinct but interrelated empirical studies. The first one asks if the NSZ program furthers environmental justice in New York City. It examines the locations of the 28 zones in terms of minority and low-income areas, as well as the inclusion of these populations in the process that led to the siting of the zones. This chapter concludes that the NSZ program improves environmental justice in New York City, both because the zones are equitably distributed in poor and minority areas, and because the planning process that led to the siting of the zones was inclusive of these populations.
      The second study examines the effectiveness of the zones at reducing traffic casualties. This analysis uses a quasi-experimental, before and after research design, with a treatment group (the Neighborhood Slow Zones) and a comparison group (similar zones that did not receive the treatment). The analysis does not detect statistically significant reductions in traffic casualties associated with the NSZs.
      The final empirical uses a policy transfer approach to compare street design in New York City’s 20-mph zones to similar zones in London. London’s “Slow Zones” were found to be effective at preventing traffic casualties (Grundy et al., 2009), and were the inspiration for New York’s Neighborhood Slow Zones.  This study analyzes the traffic calming devices transferred from the zones in London to those in New York. While street designs in London’s 20-mph zones included a robust implementation of traffic calming devices, New York’s NSZs had a much more skeletal implementation of these devices. This suggests that the nature of the transfer of street design from London to New York City contributed to the disappointing results of 20-mph zones in the latter city. Despite these findings, I argue that the NSZ program has had partial success.
title: Child Maltreatment across the Life-course: Links to Youth Offending
Creators: name: Paterson, Emily J. Hurren
Publisher: name: Griffith University
Year: 2015
Subjects: subject: Youth offending
subject: Child maltreatment

description: The links between child maltreatment and youth offending are widely accepted, but little understood (Stewart, Livingston, & Dennison, 2008). Maltreated children are at increased risk of offending, yet, the majority of maltreated children do not offend (Stewart et al., 2008). Research efforts directed at examining and explaining the links between maltreatment and offending have typically been hampered by overly simplistic operationalisations of child maltreatment. Specifically, researchers have often failed to account for the heterogeneous nature of maltreatment experiences across the life-course, and the impact of maltreatment dimensions such as type, chronicity, timing, frequency and multi-type maltreatment (Herrenkohl & Herrenkohl, 2009; Maas, Herrenkohl, & Sousa, 2008). The primary aim of this thesis was to examine the links between child maltreatment and youth offending with consideration of the heterogeneous and complex nature of child maltreatment across childhood and adolescence, within the broader developmental system and historical context.

description: We propose a model in which a spliced vector bundle (with an arbitrary number of gauge structures in the splice) possesses a geometry which do not split. The model employs connection 1-forms with values in a space-product of Lie algebras, and therefore interlaces the various gauge structures in a non-trivial manner. Special attention is given to the structure of the geometric ghost sector and the super-algebra it possesses: The ghosts emerge as $x$-dependent deformations at the gauge sector, and the associated BRST super algebra is realized as constraints that follow from the invariance of the curvature.

description: Major life events require psychological adaptations and can be accompanied by brain structural and functional changes. The goal of the current study was to investigate the association of personal growth initiative (PGI) as a form of proactive coping strategy before childbirth, with gray matter volume after delivery. Childbirth is one of the few predictable major life events, which, while being one of the most positive experiences for many, is also accompanied by multidimensional stress for the mother. Previous research has shown that high stress is associated with reductions in gray matter volume in limbic cortices as well as the prefrontal cortex (PFC). We hypothesized that PGI before childbirth is positively related to gray matter volume after delivery, especially in the ventromedial PFC (vmPFC). In a prospective study, 22 first- time mothers answered questionnaires about their PGI level 1 month before birth (T1) and 1 month after delivery (T2). Four months after giving birth, a follow-up assessment was applied with 16 of these mothers (T3). Structural brain data were acquired at both postpartal measurement occasions. Voxel-based morphometry was used to correlate prenatal PGI levels with postpartal gray matter volume. Higher PGI levels before delivery were positively associated with larger gray matter volume in the vmPFC directly after childbirth. Previous structural neuroimaging research in the context of major life events focused primarily on pathological reactions to stress (e.g., post-traumatic stress disorder; PTSD). The current study gives initial indications that proactive coping may be positively associated with gray matter volume in the vmPFC, a brain region which shows volumetric reductions in PTSD patients.

description: In this article we analyze the isotropic oscillator system on the two-dimensional sphere in the spherical systems of coordinates. The expansion coefficients for transitions between three spherical bases of the oscillator are calculated. It is shown that these coefficients are expressed through the Clebsch-Gordan coefficients for SU(2) group analytically continued to real values of their argument.
