subject: New South Wales History 19th century

description: Prior to 1965 when I began research on a topic dealing with Australian Catholic history in the 19th century X had heard only vaguely of John Hubert Plunkett. I knew that he had been a lawyer in the service of the Crown, that a street in Sydney had been named after him and, more recently, one in the suburb of Chifley in the A.C.T. The period of his service in the Colony of New South Wales threw him into contact, and perhaps contrast, with others whose names have been left to posterity so that they are remembered whilst he has been well-nigh forgotten. Wentworth, Bourke, Forbes, Gipps, Parkes and even Deniehy need no testimonial today. Their times, their lives, their motives and their utterances have been studied and written about at length. It is not possible to pick up a book on Australian history of their period that does not give them recognition. Yet when A.C.V. Melbourne wrote his lasting work on constitutional development up to 1856 he did not find room in his index for a reference to John Hubert Plunkett. John West, in an editorial in the Herald a century ago, wrote that no name would shine brighter than Plunkett's in the pages of Australian history i he was mistaken.
(Semi)simple exercises in quantum cohomology

Subjects: subject: Algebraic Geometry (math.AG)

description: The paper is dedicated to the study of algebraic manifolds whose quantum cohomology or a part of it is a semisimple Frobenius manifold. Theorem 1.8.1 says, roughly speaking, that the sum of $(p,p)$--cohomology spaces is a maximal Frobenius submanifold that has chances to be semisimple. Theorem 1.8.3 provides a version of the Reconstruction theorem, assuming semisimplicity but not $H^2$--generation. Theorem 3.6.1 establishes the semisimplicity for all del Pezzo surfaces, providing an evidence for the conjecture that semisimplicity is related to the existence of a full system of exceptional sheaves of the appropriate length. Finally, in §2 we calculate special coordinates for three families of Fano threefolds with minimal cohomology.

description: As the size and source of network traffic increase, so does the challenge of monitoring and analysing network traffic. Therefore, sampling algorithms are often used to alleviate these scalability issues. However, the use of high entropy data streams, through the use of either encryption or compression, further compounds the challenge as current state of the art algorithms cannot accurately and efficiently differentiate between encrypted and compressed packets. In this work, we propose a novel traffic classification method named HEDGE (High Entropy DistinGuishEr) to distinguish between compressed and encrypted traffic. HEDGE is based on the evaluation of the randomness of the data streams and can be applied to individual packets without the need to have access to the entire stream. Findings from the evaluation show that our approach outperforms current state of the art. We also make available our statistically sound dataset, based on known benchmarks, to the wider research community.

A study of the beta Cephei stars

Publisher: name: The Australian National University
Year: 1971
Subjects: subject: Cepheids

description: The β Cephei stars are a group of short period variable stars which have been known to astronomers since shortly after the turn of the century. The group prototype, β Cephei, was found by Frost at Yerkes in 1902 while conducting radial velocity observations. The problems associated with interpreting the short period of 4.5 hours in the radial velocity variations in terms of a binary hypothesis were immediately apparent . These problems were compounded by Guthnick's discovery in 1913 that light variations of .05 mag occurred but that these did not resemble the variations in eclipsing variables.

description: PURPOSECALGB 40603 (NCT00861705), a 2 × 2 randomized phase II trial, demonstrated that adding carboplatin or bevacizumab to weekly paclitaxel (wP) followed by doxorubicin and cyclophosphamide significantly increased the pathologic complete response (pCR) rate in stage II-III triple-negative breast cancer. We now report long-term outcomes (LTOs) and correlative science end points.PATIENTS AND METHODSThe Kaplan-Meier method was used to estimate LTOs in 443 patients who initiated study treatment. Log-rank tests and Cox proportional hazards models evaluated the impact of clinical characteristics, pathologic response, calculated residual cancer burden (RCB) in patients with residual disease (RD), treatment assignment, and dose delivery during wP on LTOs, including event-free survival (EFS). Genomic predictors of treatment response and outcomes were assessed on pretreatment tumor samples by mRNA sequencing.RESULTSAmong baseline characteristics, only the clinical stage was associated with LTOs. At a median follow-up of 7.9 years, LTOs were not significantly improved with either carboplatin or bevacizumab, overall or in patients with basal-like subtype cancers by genomic analysis. Patients with pCR (n = 205, 46.3%) had significantly higher 5-year EFS (85.5% v 56.6%, log-rank P <.0001) and overall survival (87.9% v 63.4%, P <.0001) rates compared with patients with RD, even those with RCB class I. Among clinical and genomic features, evidence of immune activation, including tumor-infiltrating lymphocytes and low B-cell receptor evenness, was associated with pCR and improved EFS.CONCLUSIONDespite higher pCR rates, neither carboplatin nor bevacizumab appeared to improve LTOs although the study was not powered to assess these secondary end points. pCR was associated with superior LTOs even when compared with minimal RD. Markers of immune activation in pretreatment tumor biopsies were independently associated with higher pCR rates and improved survival.
The application of beam transport theory to mass spectrometer design

Publisher: name: The Australian National University

Subjects: subject: Mass spectrometry
subject: Electron optics

description: The basic contention of this thesis is that the concepts and techniques of beam transport theory ca,n be usefully applied to mass spectrometer design. Most important aimong these concepts is that of the beam emittance, which is the area occupied by the ions of the beam in a phase space defined by the transverse (y or z) displacement and the corresponding conjugate momentum. It can be shown that the emittances in both y and z phase spaces are finite and that, for surface ionization sources, their magnitude is due to the initial Maxwellian velocity distribution of the thermal ions. For maximum transmission these emittances must be matched to the phase space acceptances of the magnetic analyser and collector system. A theoretical study has led to the design of a system, consisting of three quadrupole lenses, which should provide the required matching between ion source and analyser. Such a system can be expected to yield high ion transmission efficiency, of the order of 60 per cent, and to function in a predictable manner. A mass spectrometer incorporation of the above theoretical focussing system has been constructed and tested. The results of these preliminary tests indicate that the instrument is functioning approximately according to expectations.

While in General Relativity the equation of state is p is equal to minus rho, here we find p proportional to rho, where the proportionality constant is smaller than -2/3. The negativity of cosmic pressure implies acceleration of the expansion, even with lambda < 0 >.

description: A monomial-Cartesian code is an evaluation code defined by evaluating a set of monomials over a Cartesian product. It is a generalization of some families of codes in the literature, for instance toric codes, affine Cartesian codes and $J$-affine variety codes. In this work we use the vanishing ideal of the Cartesian product to give a description of the dual of a monomial-Cartesian code. Then we use such description of the dual to prove the existence of quantum error correcting codes and MDS quantum error correcting codes. Finally we show that the direct product of monomial-Cartesian codes is a locally recoverable code with $t$-availability if at least $t$ of the components are locally recoverable codes.

description: 4-dimensional homogeneous isotropic cosmological models obtained from solutions of vacuum 5-dimensional Einstein equations are considered. It is assumed, that the G(55)-component of the 5-d metric simulates matter in the comoving frame of reference. Observable 4-d metric is defined up to conformal transformations of the metric of 4-d section \tilde{g}, with a conformal factor as a function of the component G(55). It is demonstrated, that the form of this function determines the matter equation of state. Possible equations of state are analyzed separately for flat, open and close models.

Autonomous skill discovery with Quality-Diversity and Unsupervised Descriptors

description: Quality-Diversity optimization is a new family of optimization algorithms that, instead of searching for a single optimal solution to solving a task, searches for a large collection of solutions that all solve the task in a different way. This approach is particularly promising for learning behavioral repertoires in robotics, as such a diversity of behaviors enables robots to be more versatile and resilient. However, these algorithms require the user to manually define behavioral descriptors, which is used to determine whether two solutions are different or similar. The choice of a behavioral descriptor is crucial, as it completely changes the solution types that the algorithm derives. In this paper, we introduce a new method to automatically define this descriptor by combining Quality-Diversity algorithms with unsupervised dimensionality reduction algorithms. This approach enables robots to autonomously discover the range of their capabilities while interacting with their environment. The results from two experimental scenarios demonstrate that robot can autonomously discover a large range of possible behaviors, without any prior knowledge about their morphology and environment. Furthermore, these behaviors are deemed to be similar to handcrafted solutions that uses domain knowledge and significantly more diverse than when using existing unsupervised methods.

The estimation of continuous-time systems using discrete data
Creators: name: Robinson, Peter Michael
Publisher: name: The Australian National University
Year: 1972
Subjects: subject: Time-series analysis
subject: Economics, Mathematical

description: This thesis is concerned with the estimation of parameters in continuous-time systems, when the available data consist of time series sampled at regular intervals of time. Chapter 1 begins with a discussion of the circumstances in which the work may be relevant. We also describe useful results in matrix theory and in the spectral theory of continuous stationary processes. In Chapter 2 the general continuous-time model is specified by a sequence of detailed assumptions. It may be regarded as the solution of a system that is linear in the endogenous and exogenous variables, the parameters possibly occuring in a non-linear fashion and satisfying non-linear constraints. The basic method of estimation involves the Fourier transformation of the model and the insertion of the discrete Fourier transforms to produce an approximate model that is of regression type and is thus relatively easy to handle, although the estimation must generally rely on numerical methods. We establish the strong consistency of the estimates and the asymptotic normality of the normed estimates with respect to the true model. We do not assume independence or normality for our processes but under our, much weaker, conditions the Fourier transformed residuals have these properties in large samples and it is then possible to choose estimates which are, in a sense, efficient. The topic of Chapter 3 is the estimation of a regression matrix of less than full rank, a problem related to canonical correlation analysis. Asymptotic theory follows from the previous chapter since a non-linear regression approach is employed but the model is unlagged and much of this work was carried out before the author thought of the general model of Chapter 2. Possible computational procedures are suggested and the related problem of regression on an unobservable variable is considered .

description: As the most commonly used hole transport material (HTM) in tin-lead (Sn-Pb) perovskite solar cells (PSCs), poly(3,4-ethylenedioxythiophene) polystyrenesulfonate (PEDOT:PSS) limits the power conversion efficiency (PCE) and stability of the PSCs due to its acidic characteristics. Herein, an easily synthesized polymer HTM poly[(phenyl)imino[9-(2-ethylhexyl)carbazole]-2,7-diyl] (CzAn) with a shallow highest occupied molecular orbital (HOMO) level of -4.95 eV is used in a p-i-n structure, methylammonium-free, Sn-Pb PSC to replace PEDOT:PSS. Upon optimization using doping and surface engineering, high quality Sn-Pb PSCs could be successfully fabricated, boosting the PCE to 22.6% (stabilized PCE of 21.3%) compared with 21.2% for PEDOT:PSS. The perovskite films prepared on the modified CzAn HTM possess improved crystallinity, reduced trap-state density, and larger carrier mobility resulting in PSCs with greatly improved stability.

description: We approach quantum dynamics in one spatial dimension from a systematic study of moments starting from the dynamics of the mean position. This is complementary to the approach of Brizuela whose starting point was generalized recursion relations between moments. The infinite set of coupled equations is truncated which allows us to use the techniques used in the study of dynamical systems. In particular we predict for what initial variance the purely quartic oscillator will time develop with minimal change in the shape of the initial packet and what the frequency of oscillation of the mean position will be. We show how quantum fluctuations will cause a particle to escape from the well of a volcano potential and how they will cause an oscillation between the two wells of a double well potential. Further, we consider an oscillatory external field in addition to the double well potential and work near the separatrix where the classical system is known to be chaotic. We show how the quantum fluctuations suppresses the chaotic behaviour after a time interval inversely proportional to the strength of the quantum fluctuations.

subject: Science, technology and engineering curriculum and pedagogy

description: An understanding of the complex interplay between student learning and teacher aptitude with novel instructional approaches is vital to effective application of instructional design principles, practices, and application. This dissertation uses three separate research articles to triangulate integrated STEM instructional design promising practices. The guiding questions behind this effort are 1) what instructional design constraints are associated with creation/implementation of integrated STEM instructional approaches, and 2) how can integrated STEM educative technology be leveraged to address technology literacy issues within siloed STEM education and career fields. Exploration into these questions included conducting research into the impact of incorporating novel technology learning activities to enhance pre-service elementary teacher competence and self-efficacy while reducing science activity facilitation anxiety. This mixed-methods study indicates that novel learning activities have a limited effect on improving pre-service teacher self-efficacy, confidence, and competence. However, they do provide important commentary on the likelihood of adoption into future classrooms. When combining all four STEM subjects in a K-12 setting, a thoughtful planning process and formative instructional approach can promote successful integration of STEM disciplines and promote adoption by in-service K-12 teachers. A mixed-methods case study found that application of an instructional approach usability scale provides a standard of instructional design (ID) promising practice regarding curriculum design, development, and implementation for integrated STEM ID projects. Finally, perceptions and experiences with curriculum integrating all four STEM disciplines over 16 weeks were used to inform integrated STEM design decisions promoting teacher/student competency. Here, research found purposeful integration of math and engineering objectives with science content assisted students in making connections across STEM disciplines. The research described in this thesis demonstrates that all students undergo uniquely personal learning experiences. Moreover, it was discovered that teacher perceptions of instruction approach usability provides an instructional designer with critical information about accessibility of instructional approach, curriculum content, and organization as well as proposed teacher’s role in the learning process. Furthermore, instructional designers working on integrated STEM ID projects should be cognizant of STEM practices, thinking, communication, technology, and tools. Thus, a framework is proposed for monitoring STEM practices, thinking, and communication across resulting integrated STEM curriculum.

description: Dictionary based classifiers are a family of algorithms for time series classification (TSC), that focus on capturing the frequency of pattern occurrences in a time series. The ensemble based Bag of Symbolic Fourier Approximation Symbols (BOSS) was found to be a top performing TSC algorithm in a recent evaluation, as well as the best performing dictionary based classifier. A recent addition to the category, the Word Extraction for Time Series Classification (WEASEL), claims an improvement on this performance. Both of these algorithms however have non-trivial scalability issues, taking a considerable amount of build time and space on larger datasets. We evaluate changes to the way BOSS chooses classifiers for its ensemble, replacing its parameter search with random selection. This change allows for the easy implementation of contracting, setting a build time limit for the classifier and check-pointing, saving progress during the classifiers build. To differentiate between the two BOSS ensemble methods we refer to our randomised version as RBOSS. Additionally we test the application of common ensembling techniques to help retain accuracy from the loss of the BOSS parameter search. We achieve a significant reduction in build time without a significant change in accuracy on average when compared to BOSS by creating a size $n$ weighted ensemble selecting the best performers from $k$ randomly chosen parameter sets. Our experiments are conducted on datasets from the recently expanded UCR time series archive. We demonstrate the usability improvements to RBOSS with a case study using a large whale acoustics dataset for which BOSS proved infeasible.

description: We investigate if, for a locally compact group $G$, the Fourier algebra $A(G)$ is biflat in the sense of quantized Banach homology. A central role in our investigation is played by the notion of an approximate indicator of a closed subgroup of $G$: The Fourier algebra is operator biflat whenever the diagonal in $G \times G$ has an approximate indicator. Although we have been unable to settle the question of whether $A(G)$ is always operator biflat, we show that, for $G = SL(3,C)$, the diagonal in $G \times G$ fails to have an approximate indicator.

description: Polycystic ovary syndrome (PCOS) is associated with increased risk of endometrial cancer. There is growing evidence that prolactin and its receptor (PRLR) are involved in the development of cancer. We assessed endometrial expression of PRLR mRNA, and immunostaining of PRLR and the proliferation marker Ki67 on different cycle days in obese (OB-PCOS) and normal-weight women with PCOS and body mass index-matched controls. The OB-PCOS group underwent a 3 months lifestyle intervention. Prior to intervention, obese women with PCOS and controls had lower endometrial levels of PRLR mRNA in proliferative endometrium than the normal-weight groups (p p p = .004). A corresponding change within the cycle was not found in OB-PCOS women. Immunostaining of PRLR in the secretory phase correlated positively with Ki67 (p Trial registration: ISRCTN, ISRCTN18400086, https://doi.org/10.1186/ISRCTN18400086

description: With the emergence of glycated hemoglobin as a diagnostic test for diabetes, oral glucose tolerance tests (OGTTs) have become rare in endocrinology practice. As they have moved out of favor, the importance of patient instructions on preparation prior to OGTT has faded from memory. Decades-old literature, well-known to endocrinologists a generation ago, emphasized the importance of carbohydrate intake prior to OGTT. In this expert endocrine consult, we discuss an OGTT performed in a research setting without adequate carbohydrate intake at the evening meal prior to the OGTT. The resultant elevated plasma glucose levels at 1-hour and 2-hours mimicked the loss of first-phase insulin release seen in early type 1 and type 2 diabetes. With clinical concern that the research participant had evolving type 1 or type 2 diabetes, the volunteer was subjected to additional testing and experienced anxiety. Repeat OGTT was normal after adequate carbohydrate intake (>150 grams/day and >50 grams the evening prior to overnight fast for the study). The physiology of this phenomenon is explored and is likely mediated through beta cell adaptation and alteration in peripheral glucose uptake in response to nutrient exposure. The learnings of decades ago have clearly faded, and this literature should be revisited to ensure that OGTT results are not compromised when ordered for clinical or research purposes.

description: The content of this thesis is grouped into four separate contributions to the field of Surface Physics. a) Critical Point Nucleation Theory. A theory of nucleation of metastable liquids or gases near the critical point is presented. The Cahn-Hilliard theory of inhomogeneous systems is combined with Widom's theory of the free energy of uniform fluids in the two phase region near the critical point, to find the free energy W of formation of a critical nucleus in this region. By introducing an experimental criterion on W for the condensation of a metastable gas, we are able to calculate the metastability limit as a function of temperature, and to compare it with the experimental results of Dahl and Moldover, and a theory of Eggington. b) Physical Theory of Surface Tension. We apply the Lifshitz' theory of van der Waals forces to the inhomogeneity created by the diffuse region in a fluid interface. This enables us to discuss the reason for the stability of the diffuse interface, and to calculate surface tensions and interface widths to within the correct order of magnitude, as a function of temperature near the critical point. As with other continuum theories of the diffuse interface, our theory will not reduce to the low temperature "sharp interface" limit. However it has a much sounder physical basis, and avoids the mean field approximation which is usually the starting point for alternative theories. c) Interaction Theory of Fibrous Bed Filtration. A fundamental theory of the coalescence of emulsion droplets in fibrous bed filters is presented by considering the interaction of droplets with fibres and with other free and attached droplets. It is possible to explain why some filters work and others do not, and to present some predictions which can be tested by experiment. The experiments of Sareen, which are the only known experiments on filters with controlled and known electrolyte concentrations in general support our theory. d) Interaction of Adsorbed Molecules. We apply Lifshitz' theory of van der Waals forces to the problem of the interaction of two dipoles and a plane. This is used as a model for the interaction of molecules in a two dimensional gas adsorbed on the surface of a solid substrate. It is shown that the critical temperature of this gas is different from that normally calculated by applying dimensional considerations to the known three dimensional gas critical temperature.

description: We present 20 newly discovered candidates for binary systems with an RR~Lyrae companion. Using the photometric data from the Optical Gravitational Lensing Experiment (OGLE) and Korea Microlensing Telescope Network (KMTNet) for the Galactic bulge, we searched for binary candidates among non-modulated fundamental-mode RR~Lyrae variables. We constructed and investigated over 9000 $O-C$ diagrams for individual pulsators, in order to find signs of the light-travel time effect. We found 20 variables exhibiting cyclic variation in the $O-C$ (time of the observed minus calculated brightness maximum) diagram, which can be associated with a second component in the system, but for confirmation of binarity, a long-term radial velocity study is necessary. The modeling of the $O-C$ diagrams yields orbital parameters, estimates of the semi-amplitude of the radial velocity curve, and the mass function. The orbital periods of our candidates range from 3 to 15 years. Two of the binary candidates display a minimum mass higher than the assumed mass of the RR~Lyrae component, which points towards an evolved companion that can under some circumstances contribute significantly to the total light of the system.

A study of radiating argon flows at high opacities
Creators: name: Logan, Peter Frederick
Publisher: name: The Australian National University
Year: 1972
Subjects: subject: Gas flow
subject: Shock tubes
subject: Argon

description: The aim of this project was to investigate the effect of radiation loss on the various flows associated with a free piston reflected shock tunnel assembly. Experiments have been performed using argon as a test gas because the radiation loss with argon is quite considerable under the thermodynamic conditions experienced in this study. The nature of the experiments was mainly spectroscopic. This investigation has shown that?using a careful analysis^the behaviour of a high performance shock tunnel?which experiences substantial radiation losses.can be explained during the first one hundred microseconds of test section flow. An appropriate model is developed to account for the emitted and absorbed radiation from the test gas, both behind the incident shock and the reflected shock, during this period. At later times a quantitative description could not be obtained since interaction between the reflected shock and the boundary layer introduced contamination into the reflected shock region. From the theoretical analysis of the radiative behaviour of the gas flows associated with free piston reflected shock tunnels, a limiting value for their operation can be obtained. A further study proceeded from this investigation. The gas in the stationary slug at the end of the shock tube is optically opaque towards all visible and near visible radiation. Whereas the gas at the exit of the nozzle is optically thin. Hence the radiation field observed looking up the centre of the nozzle is similar to that of a stellar atmosphere?and a Fraunhofer type spectrum was observed. A preliminary investigation of both the mechanism by which the spectral lines are formed#and their application^is reported.

description: We prove the existence of a weak solution to the equations describing the inertial motions of a coupled system constituted by a rigid body containing a viscous compressible fluid. We then provide a weak-strong uniqueness result that allows us to completely characterize, under certain physical assumptions, the asymptotic behavior in time of the weak solution corresponding to smooth data of restricted "size" and show that it tends to a uniquely determined steady-state.

description: The properties of excited states of ²⁷A1 and ³²S have been investigated by various techniques of gamma-ray and charged particle spectroscopy. Chapter I describes several nuclear models which have had some success in describing the known properties of nuclei in the 2s-ld shell. Brief reviews of attempts to describe ²⁷A1 and ³²S in terms of nuclear models are given in chapters 3 and 4. The principles and theory behind the Doppler shift attenuation method (DSAM) and gamma-ray angular distribution and polarisation experiments are outlined in chapter 2,together with a brief description of the 61 cm double focussing magnetic spectrometer.

description: We investigate the robustness of some recent results obtained for homogeneous and isotropic cosmological models with conformally coupled scalar fields. For this purpose, we investigate anisotropic homogeneous solutions of the models described by the action $$ S=\int d^4x \sqrt{-g}\left\{F(ϕ)R - \partial_aϕ\partial^aϕ-2V(ϕ) \right\}, $$ with general $F(ϕ)$ and $V(ϕ)$. We show that such a class of models leads generically to geometrical singularities if for some value of $ϕ$, $F(ϕ)=0$, rendering previous cosmological results obtained for the conformal coupling case highly unstable. We show that stable models can be obtained for suitable choices of $F(ϕ)$ and $V(ϕ)$. Implications for other recent results are also discussed.

description: Introduction: Increasing interest in real-world evidence has fueled the development of study designs incorporating real-world data (RWD). Using the Causal Roadmap, we specify three designs to evaluate the difference in risk of major adverse cardiovascular events (MACE) with oral semaglutide versus standard-of-care: 1) the actual sequence of non-inferiority and superiority randomized controlled trials (RCTs), 2) a single RCT, and 3) a hybrid randomizedexternal data study. Methods: The hybrid design considers integration of the PIONEER 6 RCT with RWD controls using the experiment-selector cross-validated targeted maximum likelihood estimator. We evaluate 95% confidence interval coverage, power, and average patient-time during which participants would be precluded from receiving a glucagon-like peptide-1 receptor agonist (GLP1-RA) for each design using simulations. Finally, we estimate the effect of oral semaglutide on MACE for the hybrid PIONEER 6-RWD analysis. Results: In simulations, Designs 1 and 2 performed similarly. The tradeoff between decreased coverage and patient-time without the possibility of a GLP1-RA for Designs 1 and 3 depended on the simulated bias. In real data analysis using Design 3, external controls were integrated in 84% of cross-validation folds, resulting in an estimated risk difference of -1.53%-points (95% CI -2.75%-points to -0.30%-points). Conclusions: The Causal Roadmap helps investigators to minimize potential bias in studies using RWD and to quantify tradeoffs between study designs. The simulation results help to interpret the level of evidence provided by the real data analysis in support of the superiority of oral semaglutide versus standard-of-care for cardiovascular risk reduction.

description: We continue the study of linear families of contact forms on 3-manifolds begun in our paper `Contact geometry and complex surfaces'. The present paper introduces Teichmuller and moduli spaces for so-called taut contact circles. By constructing a developing map for taut contact circles, we show that these geometrically defined deformation spaces are equivalent to certain spaces of representations of the fundamental group in appropriate Lie groups. Furthermore, we relate these deformation spaces to `classical' Teichmuller theory of Riemann surfaces and orbifolds.

The question of the Asiatic mode of production : towards a new Marxist historiography
Creators: name: Sawer, Marian
Publisher: name: The Australian National University
Year: 1974
Subjects: subject: Marx, Karl, 1818-1883. Asiatic mode of production
subject: Marxian economics

description: This thesis represents the first book-length account in the English language of Marx's concept of the Asiatic mode of production and of its implications for historical materialism. It examines the origins of the concept, its place and functions within the work of Marx and Engels and of subsequent Marxists, and its relevance to contemporary Marxism. In doing so, it takes into account not only the intellectual history of the concept but its political history; and not only its theoretical implications for historical materialism but its political implications for the Marxist approach to the non-Westem world.
