The counsellor's self in therapy
Creators: name: Reupert, Andrea E.
Publisher: name: La Trobe
Year: 2023

description: The person of the counsellor, or what is sometimes referred to as the counsellor's self, is the focus of this thesis. How the counsellor's self is described and manifested during therapy constitute the two main research questions. Various perspectives are presented from psychoanalysis, behaviour therapy, cognitive behaviour therapy, person centered therapy and systems therapy. While issues pertaining to the counsellor's self have been explored predominately by systems therapists, this study extends previous research by involving interviews with counsellors from a range of orientations.The study is conducted within an interpretative research paradigm, and data are collected and interpreted according to a qualitative approach. Semi-structured interviews with 16 counsellors, from a range of theoretical orientations, constitute the primary method of data collection. Other data sources include a short questionnaire sent to the same counsellors, the researcher's reflective journal as well as recorded meetings between a peer debriefer and the researcher.Study participants describe the counsellor's self as a multifaceted, positive and integrated entity. The counsellor's self includes participant's professional knowledge and skills as well as their beliefs, values, thoughts, feelings, personal style and an unknown aspect of self that some participants referred to as their unconscious. While somewhat influenced by past relationships and the client, the counsellor's self is primarily autonomous and defined by the individual counsellor. Although the counsellor's self has the capacity to change over time, in different environments and with different clients, the self also includes notions of stability and consistency. The counsellor's self is involved in therapy as an inevitable presence, a deliberate tool and a stance. Participants highlighted the importance of self-awareness and various professional and personal constraints on the involvement of self. A central function of the self in therapy is in the therapeutic alliance. The study has implications for the training and supervision of counsellors and future psychotherapeutic research.
Electric polarization induced by phase separation in magnetically ordered and paramagnetic states of RMn2O5 (R=Gd, Bi)

description: The electric polarization hysteresis loops and remanent polarization were revealed in multiferroics RMn$_2$O$_5$ with $R = Gd$ and $Bi$ at wide temperature interval from 5 K up to 330 K. Until recently, the long-range ferroelectric order having an exchange-striction magnetic nature had been observed in RMn$_2$O$_5$ only at low temperatures ($T\leq T_C = 30$ -- 35 K). We believe that the polarization we observed was caused by the frozen superparaelectric state which was formed by the restricted polar domains resulting from phase separation and charge carriers self-organization. At some sufficiently high temperatures $T\gg T_C$ the frozen superparaelectric state was destroyed, and the conventional superparaelectric state occurred. This happened when the potential barriers of the restricted polar domain reorientations become equal to the kinetic energy of the itinerant electrons (leakage). The hysteresis loops were measured by the so-called PUND method which allowed us to correctly subtract the contribution of conductivity from the measured polarization. The correlations between properties of the phase separation domains and polarization were revealed and studied. The high-temperature polarization also had a magnetic nature and was controlled by the magnetic field because the double exchange between pairs of Mn ions with different valences (Mn$^{3+}$ and Mn$^{4+}$) in RMn$_2$O$_5$ was the basic interaction resulting in phase separation.

Developing casemix classification for acute hospital inpatients in Chengdu, China
Creators: name: Gong, Zhiping
Publisher: name: La Trobe
Year: 2023

description: Abstract: Hospital information systems in China are improving and a casemix system for describing inpatient care is looking more feasible than previously. Implementing a casemix classification system for acute inpatient care in China could help to improve regional planning and hospital quality and efficiency. The purpose of this study was to evaluate the Australian DRG system as the basis for developing an acute inpatient casemix system appropriate for China. The applicability of the Australian AR-DRG system has been evaluated (in terms of homogeneity achieved and comparability of rank order) using inpatient data from Chengdu in Sichuan.Homogeneity achieved was good. The R2 value (the coefficient of multiple determination) was 0.12 for LOS and 0.17 for cost using untrimmed data and using (L3H3) trimmed data, R2 was 0.45 for LOS and 0.59 for cost. This explanatory power is comparable to other DRG classification systems although there are a few MDCs in which AR-DRGs exhibit poorer explanatory power.Rank order of groups was generally comparable. The AR-DRG system incorporates hierarchies of DRGs within groups of adjacent DRGs, within medical and surgical partitions and across all DRGs within each MDC. I have compared the ranking of DRGs based on average cost with the ranking assumed by the AR-DRG system, at the adjacent group level, within partitions and at the level of the MDC. I used the Spearman Rank Correlation coefficient to compare DRG order across partitions and whole MDCs. In general the cost relativities of the Chinese inpatient episodes grouped by the AR-DRG system correspond to the logical hierarchies assumed by the system. On this basis Chinese and Australian episodes of care within most of the MDCs appear to reflect the same broad pattern of resource consumption.Further research will be needed to determine where and how the grouping rules used in the AR-DRG system might need to be changed to more accurately reflect Chinese circumstances. For example the cost structures of Chinese health services are different from those in Australia. The Australian Refined DRGs (AR-DRGs) would provide a sound basis from which to develop a Chinese version of DRGs.

Year: 2016
Subjects: subject: Distributed, Parallel, and Cluster Computing (cs.DC)

description: In this paper we propose and prove that cyclic quorum sets can efficiently manage all-pairs computations and data replication. The quorums are O(N/sqrt(P)) in size, up to 50% smaller than the dual N/sqrt(P) array implementations, and significantly smaller than solutions requiring all data. Implementation evaluation demonstrated scalability on real datasets with a 7x speed up on 8 nodes with 1/3rd the memory usage per process. The all-pairs problem requires all data elements to be paired with all other data elements. These all-pair problems occur in many science fields, which has led to their continued interest. Additionally, as datasets grow in size, new methods like these that can reduce memory footprints and distribute work equally across compute nodes will be demanded.

description: Spatial self-phase modulation (SSPM) is the optical nonlinear process and is a result of spatially varying refractive index profile along the line of propagation in a medium. SSPM is proved to be a method to demonstrate different photonic functionalities. Transition metal dichalcogenides play a key role in 2D nanophononics due to their unique and fascinating properties. MoS2 is the widely studied layered TMDs among all other 2D materials. This paper demonstrates such photonic functionality using thermally induced nonlinear optical response SSPM method, of MoS2 nano bottles. Thermally induced nonlinear optical parameters have been estimated by utilizing the saturable absorption response of h- BN, the nonreciprocal light propagation has been achieved. The diode actions have also been demonstrated in liquid-solid and solid-solid devices with the help of passive elements.
The employment relationship and integrated theory
Creators: name: Sansbury, George Ernest
Publisher: name: La Trobe
Year: 2023

description: This research falls within the field of normative business ethics. Its aim is to examine the moral nature of the employment relationship in western democracies by examining the liberal, democratic justifications that are normally advanced for its probity. Its concern is to challenge the notion that the employment relationship is in conformity with these liberal democratic values. Thus, the research is an exercise in the examination of the application of the liberal, democratic tradition to the social institution of employment. Thus research examines areas of dissonance between the political relationship of employee - employer and the dominant values of the liberal tradition found elsewhere in western democracies. The research firstly identifies the key moral characteristics of the employment relationship in private, capitalist organisations. This is derived from a consideration of the development historically, of the employment relationship, with acknowledgement of the combined influences of statute, common law, contract law and custom in forming the current employee relationship. Secondly, the research identifies the justificatory arguments from the liberal tradition that are normally advanced in support of the employment relationship's moral probity. These include notions of rights deriving from private property, the separation of social life into public and private spheres and the application of contract law to employment. Thirdly, the research examines these arguments for their moral probity. Specifically, this involves an examination of the arguments regarding the private property status of employing organisations, the application of contract law to employment, the moral characteristics of the master and servant relationship as a basis for employment and the relevance of democratic values within employment. As an additional perspective, the literature on human needs is reviewed as a source, outside of the liberal tradition, for a basis upon which to outline the moral requirements of human relationships to work.

History and collective memory of the Italian migrant workers' organisation FILEF in 1970s Melbourne
Creators: name: Battiston, Simone
Publisher: name: La Trobe
Year: 2023

description: Abstract: This doctoral dissertation seeks to investigate the reasons that lay behind the rise, success and decline of the Italian-run migrant workers' organisation FILEF during the 1970s in Melbourne by reviewing and discussing some significant historical events. It does so in light of the existing literature, archival data and a string of oral accounts gathered from former and current key FILEF members and collaborators. It is hereby offering a better understanding of an otherwise poorly researched area of the Italian-Australian left-wing grassroots organisations in post-war Australia. The thesis has been divided into two parts, including introduction and conclusion. Part One (Chapters 1-5) reviews the historical and political background (in both Italy and Australia) that favoured the establishment of FILEF in Australia, including Melbourne, in the early 1970s; Part Two (Chapters 6-9) presents an analysis of the historical development and socio-political role of FILEF Melbourne between 1972 and 1980.Chapter One reviews the theoretical context, the representation of the history of FILEF in previous publications, primary and secondary sources, the research strategy and methodology. Chapters Two and Three anchor the history of FILEF Melbourne to their respective background in Italy and Australia. That is, Chapter Two examines the post-war Italian emigration and its politicising by the Italian left; Chapter Three focuses on the post-war emigration of Italians to Australia and outlines a profile of the Italian-Australian community. Chapter Four maps the route of the Italian-Australian Left in the 1950s and 1960s, that is from Italia Libera to the Lega Italo-Australiana. Chapter Five reviews the circumstances that led to the establishment of the PCI in Australia respectively. Chapter Six examines the origins and grassroots activism of FILEF in Melbourne in the 1970s, especially by looking at three areas of activity: migrant press, migrant welfare and migrant politics. Chapter Seven researches the vulnerability of FILEF to the pressures of conservative quarters by recounting the "Italian communist move in" (1975) and the federal funding cut (1976) episodes. Chapter Eight, thoroughly revisits the Salemi case (1977), while Chapter Nine explores the effects of the case and Salemi's deportation on FILEF towards the end of the 1970s.

Drifting states and synchronization induced chaos in autonomous networks of excitable neurons

description: The study of balanced networks of excitatory and inhibitory neurons has led to several open questions. On the one hand it is yet unclear whether the asynchronous state observed in the brain is autonomously generated, or if it results from the interplay between external drivings and internal dynamics. It is also not known, which kind of network variabilities will lead to irregular spiking and which to synchronous firing states. Here we show how isolated networks of purely excitatory neurons generically show asynchronous firing whenever a minimal level of structural variability is present together with a refractory period. Our autonomous networks are composed of excitable units, in the form of leaky integrators spiking only in response to driving inputs. For a non-uniform network, composed exclusively of excitatory neurons, we find a rich repertoire of self-induced dynamical states, including asynchronous drifting states, fully synchronized, or mixed, containing both drifting and synchronized components. The individual neurons considered are excitable and hence do not dispose of intrinsic natural firing frequencies. An effective network-wide distribution of natural frequencies is however generated autonomously through self-consistent feedback loops. We find two types of asynchronous activity, with the individual neurons spiking regularly in the pure drifting state, albeit with a continuous distribution of firing frequencies. The activity of the drifting component, however, becomes irregular in the mixed state, due to the periodic driving of the synchronized component. We propose a new tool for the study of chaos in spiking neural networks, which consists of an analysis of the time series of pairs of consecutive interspike intervals. In this space, we show that a strange attractor with a fractal dimension is formed.

description: The spin-orbit interaction couples the electrons' motion to their spin. Accordingly, passing a current in a material with strong spin-orbit coupling generates a transverse spin current (spin Hall effect, SHE) and vice-versa (inverse spin Hall effect, ISHE). The emergence of SHE and ISHE as charge-to-spin interconversion mechanisms offers a variety of novel spintronics functionalities and devices, some of which do not require any ferromagnetic material. However, the interconversion efficiency of SHE and ISHE (spin Hall angle) is a bulk property that rarely exceeds ten percent, and does not take advantage of interfacial and low-dimensional effects otherwise ubiquitous in spintronics hetero- and mesostructures. Here, we make use of an interface-driven spin-orbit coupling mechanism - the Rashba effect - in the oxide two-dimensional electron system (2DES) LaAlO3/SrTiO3 to achieve spin-to-charge conversion with unprecedented efficiency. Through spin-pumping, we inject a spin current from a NiFe film into the oxide 2DES and detect the resulting charge current, which can be strongly modulated by a gate voltage. We discuss the amplitude of the effect and its gate dependence on the basis of the electronic structure of the 2DES.

description: FLARE (First Light And Reionization Explorer) is a space mission that will be submitted to ESA (M5 call). Its primary goal (about 80% of lifetime) is to identify and study galaxies that dwell in the universe before the end of the reionization up to about z = 15, a redshift that might not be statistically reachable for JWST, Euclid and WFIRST. A secondary objective (about 20% of lifetime) is to survey star formation in the Milky Way. The strategy selected for FLARE optimizes the science return: imaging and spectroscopic integral-field observations will be carried out simultaneously on two parallel focal planes and over very wide instantaneous fields of view. FLARE will feature an instantaneous field of view of about 0.2 deg$^2$ with 0.2-arcsec pixels and an instantaneous integral-field spectroscopic field of view of about 1 arcmin$^2$ with R = 500 - 1000 and an angular resolution of about 0.4 arcsec. To detect first-light galaxies, the imaging and spectroscopic survey (parallel observations over about 6 years) will reach m$_{AB}$ = 28 and f$_λ$ = 10$^{-18}$ erg/cm$^2$/S. FLARE will help addressing two of ESA's Cosmic Vision themes: a) "How did the universe originate and what is it made of?" and b) "What are the conditions for planet formation and the emergence of life?" and more specifically, "From gas and dust to stars and planets". FLARE will provide to the ESA community a leading position to statistically study the early universe after JWST's deep but pin-hole surveys. Moreover, the instrumental development of wide-field imaging and wide-field integral-field spectroscopy in space will be a major breakthrough after making them available on ground-based telescopes.

description: Aims: Several studies suggest that the activity level of a planet-host star can be influenced by the presence of a close-by orbiting planet. Moreover, the interaction mechanisms that have been proposed, magnetic interaction and tidal interaction, exhibit a very different dependence on orbital separation between the star and the planet. A detection of activity enhancement and characterization of its dependence on planetary orbital distance can, in principle, allow us to characterize the physical mechanism behind the activity enhancement. Methods: We used the HARPS-N spectrograph to measure the stellar activity level of HD 80606 during the planetary periastron passage and compared the activity measured to that close to apastron. Being characterized by an eccentricity of 0.93 and an orbital period of 111 days, the system's extreme variation in orbital separation makes it a perfect target to test our hypothesis. Results: We find no evidence for a variation in the activity level of the star as a function of planetary orbital distance, as measured by all activity indicators employed log($R'_{HK}$), H$_α$, NaI, and HeI. None of the models employed, whether magnetic interaction or tidal interaction, provides a good description of the data. Conclusions: We find no evidence for star-planet interaction in HD\,80606 at the moment of the periastron passage of its very eccentric planet. The straightforward explanation for the non-detection is the absence of interaction as a result of a low magnetic field strength on either the planet or the star and of the low level of tidal interaction between the two. However, we cannot exclude two scenarios: i) the interaction can be instantaneous and of magnetic origin, being concentrated on the substellar point and its surrounding area, and ii) the interaction can lead to a delayed activity enhancement.

description: The development of a data management plan requires detailed knowledge about the research data and the corresponding processes. Moreover, detailed knowledge about the entire data life-cycle in the respective research group is necessary when providing support with respect to reproducibility and data management. In order to allow curators to gain this knowledge, we developed a questionnaire, which provides a set of topics including questions to inspire discussions on data management and the data life-cycle. This questionnaire consists of a collection of questions targeting different phases of the data life-cycle. It was developed in order to gain insight about the data management practices in the subproject of the collaborative research centre 1270 ELAINE, but can also be used as guideline for so interviews with individual research groups.
The human costs and benefits of work: jobload, self-perceived performance, and employee wellbeing
Creators: name: Miller, Peta
Publisher: name: La Trobe
Year: 2023

description: The primary purpose of this project was to investigate some relationships between workload and employee wellbeing. The necessary first stage was to formulate a theoretical framework - the JobLoad Model - to support a comprehensive and detailed investigation of the main factors that contribute to a job's workload. Building on the ergonomics concept of 'workload', this Model incorporates task - and job-level factors that have been identified within the research literatures of physical and cognitive ergonomics as important; additional constructs were added to take account of additional factors shown to be relevant to employee wellbeing, drawing on evidence from occupational health and organizational psychology literatures. Using this framework available questionnaire-based measurement instruments for assessing workload and employee wellbeing were reviewed, new items were developed as required, and the JobLoad Index (JLI) was developed. The JLI was used to collect data from public servants in two different workplaces, with participation rates of 63% and 73% respectively. Relationships were determined between major task, job and organisational environment factors, self-perceived performance adequacy, and various aspects of employee wellbeing including job satisfaction, physical discomfort and psychological fatigue, stress and arousal. For a sub-sample of participants in one of the two workplaces, levels of adrenaline, noradrenaline and cortisol were also measured from 24-hour urine collections. The factors measured by the JLI accounted for a very substantial proportion of variance in these various dimensions of work-related wellbeing. The results provide potentially very useful insights into the relative influences of a wide range of work-and job-related variables on people's perceived abilites to cope with their job demands, and on several aspects of their wellbeing. Further, the importance of measuring multiple dimensions of well being, and differentiating their separate sets of work-related determinants, was well demonstrated. Finally, and perhaps most significantly, this study has identified the powerful role that self-perceived performance plays as an intervening variable between job demands and people's work-related wellbeing.

description: Anhand von "Ist nicht Ephraim" aus den "Psalmen Davids" und einigen Werken, die Schütz nicht in den mit Opusnummern gezählten Drucken veröffentlicht hat, läßt sich seine Arbeit mit selbstständigen Instrumentalstimmen neu definieren; er beherrschte sie demnach schon um 1620 auf verschiedenartige Weise, nicht erst nach der Venedig-Reise 1629/30. Seine Techniken unterscheiden sich von denen seines Lehrers Giovanni Gabrieli. Die spiegeln Schütz' kompositorische Techniken der Zeit um 1620 also nicht völlig; dies läßt sich auch durch Vergleich mit Johann Crügers Bearbeitungen einzelner Werke der Sammlung beleuchten.

description: When we elastically impose a homogeneous, affine deformation on amorphous solids, they also undergo an inhomogeneous, non-affine deformation, which can have a crucial impact on the overall elastic response. To correctly understand the elastic modulus $M$, it is therefore necessary to take into account not only the affine modulus $M_A$, but also the non-affine modulus $M_N$ that arises from the non-affine deformation. In the present work, we study the bulk ($M=K$) and shear ($M=G$) moduli in static jammed particulate packings over a range of packing fractions $φ$. One novelty of this work is to elucidate the contribution of each vibrational mode to the non-affine $M_N$ through a modal decomposition of the displacement and force fields. In the vicinity of the (un)jamming transition, $φ_{c}$, the vibrational density of states, $g(ω)$, shows a plateau in the intermediate frequency regime above a characteristic frequency $ω^\ast$. We illustrate that this unusual feature apparent in $g(ω)$ is reflected in the behavior of $M_N$: As $φ\rightarrow φ_c$, where $ω^\ast \rightarrow 0$, those modes for $ω< ω^\ast$ contribute less and less, while contributions from those for $ω> ω^\ast$ approach a constant value which results in $M_N$ to approach a critical value $M_{Nc}$, as $M_N-M_{Nc} \sim ω^\ast$. At $φ_c$ itself, the bulk modulus attains a finite value $K_c=K_{Ac}-K_{Nc} > 0$, such that $K_{Nc}$ has a value that remains below $K_{Ac}$. In contrast, for the critical shear modulus $G_c$, $G_{Nc}$ and $G_{Ac}$ approach the same value so that the total value becomes exactly zero, $G_c = G_{Ac}-G_{Nc} =0$. We explore what features of the configurational and vibrational properties cause such the distinction between $K$ and $G$, allowing us to validate analytical expressions for their critical values.

description: Measures of news exposure are common in research that tries to explain political knowledge, political engagement, opinion formation and, more generally, media effects. Much of that research employs self-reported measures obtained with surveys, known to suffer from accuracy problems. Observational measures, however, also suffer from limitations derived from data collection and instrumentation. Here we offer new comparative evidence on the nature of those problems. We show that commonly used self-report measures of digital news consumption are problematic for three reasons: they only pay attention to a small fraction of all available sources; they underestimate audience share; and they distort the relative position of news sites in visibility rankings. Measurement problems, however, also exist in observational studies, especially when mobile access is excluded from data collection. Our analyses quantify the magnitude of these problems, offering unprecedented comparative evidence of online news consumption that spans nine countries and a period of five years. We discuss the implications of our findings for future research on news exposure.
Driving force for martensitic transformation in Ni$_{2}$Mn$_{1+x}$Sn$_{1-x}$

description: The martensitic transformation in Ni$_{2}$Mn$_{1+x}$Sn$_{1-x}$ alloys has been investigated within ab-initio density functional theory. The experimental trend of a martensitic transition happening beyond $x$ = 0.36 is captured within these calculations. The microscopic considerations leading to this are traced to increased Ni-Mn hybridization which results from the Ni atom experiencing a resultant force along a lattice parameter and moving towards the Mn atoms above a critical concentration. The presence of the lone pair electrons on Sn forces the movement of Ni atoms away from Sn. While band Jahn Teller effects have been associated with this transition, we show quantitatively that atleast in this class of compounds they have a minor role.

On the genealogy of branching random walks and of directed polymers

description: It is well known that the mean field theory of directed polymers in a random medium exhibits replica symmetry breaking with a distribution of overlaps which consists of two delta functions. Here we show that the leading finite size correction to this distribution of overlaps has a universal character which can be computed explicitly. Our results can also be interpreted as genealogical properties of branching Brownian motion or of branching random walks.

description: When transferring a Deep Reinforcement Learning model from simulation to the real world, the performance could be unsatisfactory since the simulation cannot imitate the real world well in many circumstances. This results in a long period of fine-tuning in the real world. This paper proposes a self-supervised vision-based DRL method that allows robots to pick and place objects effectively and efficiently when directly transferring a training model from simulation to the real world. A height-sensitive action policy is specially designed for the proposed method to deal with crowded and stacked objects in challenging environments. The training model with the proposed approach can be applied directly to a real suction task without any fine-tuning from the real world while maintaining a high suction success rate. It is also validated that our model can be deployed to suction novel objects in a real experiment with a suction success rate of 90\% without any real-world fine-tuning.

description: We explore an alternative discretization of continuum SU(N_c) Yang-Mills theory on a Euclidean spacetime lattice, originally introduced by Budzcies and Zirnbauer. In this discretization the self-interactions of the gauge field are induced by a path integral over N_b auxiliary boson fields, which are coupled linearly to the gauge field. The main progress compared to earlier approaches is that N_b can be as small as N_c. In the present paper we (i) extend the proof that the continuum limit of the new discretization reproduces Yang-Mills theory in two dimensions from gauge group U(N_c) to SU(N_c), (ii) derive refined bounds on N_b for non-integer values, and (iii) perform a perturbative calculation to match the bare parameter of the induced gauge theory to the standard lattice coupling. In follow-up papers we will present numerical evidence in support of the conjecture that the induced gauge theory reproduces Yang-Mills theory also in three and four dimensions, and explore the possibility to integrate out the gauge fields to arrive at a dual formulation of lattice QCD.

description: Spherically symmetric equilibrium configurations of perfect fluid obeying a polytropic equation of state are studied in spacetimes with a repulsive cosmological constant. The configurations are specified in terms of three parameters---the polytropic index $n$, the ratio of central pressure and central energy density of matter $σ$, and the ratio of energy density of vacuum and central density of matter $λ$. The static equilibrium configurations are determined by two coupled first-order nonlinear differential equations that are solved by numerical methods with the exception of polytropes with $n=0$ corresponding to the configurations with a uniform distribution of energy density, when the solution is given in terms of elementary functions. The geometry of the polytropes is conveniently represented by embedding diagrams of both the ordinary space geometry and the optical reference geometry reflecting some dynamical properties of the geodesic motion. The polytropes are represented by radial profiles of energy density, pressure, mass, and metric coefficients. For all tested values of $n>0$, the static equilibrium configurations with fixed parameters $n$, $σ$, are allowed only up to a critical value of the cosmological parameter $λ_{\mathrm{c}}=λ_{\mathrm{c}}(n,σ)$. In the case of $n>3$, the critical value $λ_{\mathrm{c}}$ tends to zero for special values of $σ$. The gravitational potential energy and the binding energy of the polytropes are determined and studied by numerical methods. We discuss in detail the polytropes with an extension comparable to those of the dark matter halos related to galaxies, i.e., with extension $\ell > 100\,\mathrm{kpc}$ and mass $M > 10^{12}\,\mathrm{M}_{\odot}$. ...
