title: The political economy of unequal exchange : A critique of the theory of Arghiri Emmanuel
Creators: name: Barrientos, Stephanie
Publisher: name: University of Kent
Year: 2022

description: This thesis is an examination of the political economy of Arghiri Emmanuel's theory of unequal exchange. Emmanuel's theory is studied both as a theory of trade and as a theory of imperialism. Emmanuel's original aim was to develop a modified labour theory of value to explain why in the course of international trade some nations grow rich at the expense of poor ones. This thesis argues that Emmanuel's theory of international exchange value failed as an attempt to extend the labour theory of value to international trade; it rests instead on a Smithian 'adding up' theory of value, where value is defined by the sum of the rewards to the factors. Further, it is argued that Emmanuel's attempt to explain the determination of the rewards to the factors in terms of physical bundles of goods is inadequate as an explanation of value. Consequently, it is shown that he is unable to account for the origins of surplus value or profit. As a result Emmanuel's conclusions regarding the formation of international values do not move beyond sophisticated neo-Mercantilism - where one nation grows richer at the expense of another by adding on to its cost of production a 'surplus upon alienation'. Thus Emmanuel's neo-Mercantilist theory of international exchange value and trade is shownto be logically consistent with his theory of Mercantile imperialism. But it is argued this theory is inadequate as a theory of imperialism as it is merely descriptive and fails to identify the underlying determination of the transfer of surplus from one nation to another. Having established the main failures of Emmanuel's theory of unequal exchange the thesis concludes by examining its relevance to a theory of financial imperialism.

description: Recently it was pointed out that in shift-symmetric scalar-tensor theories a black hole can have nontrivial scalar hair which depends linearly on time. We develop black hole perturbation theory for such solutions and compute the quadratic action of odd-parity perturbations. We show that around all the solutions known so far with such time-dependent scalar hair the perturbations trigger instabilities or are presumably strongly coupled.

Geometric phase in the Hopf bundle and the stability of non-linear waves

description: We develop a stability index for the traveling waves of non-linear reaction–diffusion equations using the geometric phase induced on the Hopf bundle . This can be viewed as an alternative formulation of the winding number calculation of the Evans function, whose zeros correspond to the eigenvalues of the linearization of reaction–diffusion operators about the wave. The stability of a traveling wave can be determined by the existence of eigenvalues of positive real part for the linear operator. Our for locating and counting eigenvalues is inspired by the numerical results in Way’s Way (2009). We provide a detailed proof of the relationship between the phase and eigenvalues for dynamical systems defined on and sketch the proof of the method of geometric phase for and its generalization to boundary-value problems. Implementing the numerical method, modified from Way (2009), we conclude with open questions inspired from the results.

description: We study the sensitivity of multi ton-scale time projection chambers using a liquid xenon target, e.g., the proposed DARWIN instrument, to spin-independent and spin-dependent WIMP-nucleon scattering interactions. Taking into account realistic backgrounds from the detector itself as well as from neutrinos, we examine the impact of exposure, energy threshold, background rejection efficiency and energy resolution on the dark matter sensitivity. With an exposure of 200 t x y and assuming detector parameters which have been already demonstrated experimentally, spin-independent cross sections as low as $2.5 \times 10^{-49}$ cm$^2$ can be probed for WIMP masses around 40 GeV/$c^2$. Additional improvements in terms of background rejection and exposure will further increase the sensitivity, while the ultimate WIMP science reach will be limited by neutrinos scattering coherently off the xenon nuclei.

Traveling waves for a model of gravity-driven film flows in cylindrical domains

description: Traveling wave solutions are studied for a recently-derived model of a falling viscous film on the interior of a vertical rigid tube. By identifying a Hopf bifurcation and using numerical continuation software, families of non-trivial traveling wave solutions may be traced out in parameter space. These families all contain a single solution at a ‘turnaround point’ with larger film thickness than all others in the family. In an earlier paper, it was conjectured that this turnaround point may represent a critical thickness separating two distinct flow regimes observed in physical experiments as well as two distinct types of behavior in transient solutions to the model. Here, these hypotheses are verified over a range of parameter values using a combination of numerical and analytical techniques. The linear stability of these solutions is also discussed; both large- and small-amplitude solutions are shown to be unstable, though the instability mechanisms are different for each wave type. Specifically, for small-amplitude waves, the region of relatively flat film away from the localized wave crest is subject to the same instability that makes the trivial flat-film solution unstable; for large-amplitude waves, this mechanism is present but dwarfed by a much stronger tendency to relax to a regime close to that followed by small-amplitude waves.

description: To support implementation of the Paris Agreement, the new HAPPI ensemble of 20 bias-corrected simulations of four climate models was used to drive two global hydrological models, WaterGAP and LPJmL, for assessing freshwater-related hazards and risks in worlds approximately 1.5 °C and 2 °C warmer than pre-industrial. Quasi-stationary HAPPI simulations are better suited than transient CMIP-like simulations for assessing hazards at the two targeted long-term global warming (GW) levels. We analyzed seven hydrological hazard indicators that characterize freshwater-related hazards for humans, freshwater biota and vegetation. Using a strict definition for significant differences, we identified for all but one indicator that areas with either significantly wetter or drier conditions (calculated as percent changes from 2006–2015) are smaller in the 1.5 °C world. For example, 7 day high flow is projected to increase significantly on 11% and 21% of the global land area at 1.5 °C and 2 °C, respectively. However, differences between hydrological hazards at the two GW levels are significant on less than 12% of the area. GW affects a larger area and more people by increases—rather than by decreases—of mean annual and 1-in-10 dry year streamflow, 7 day high flow, and groundwater recharge. The opposite is true for 7 day low flow, maximum snow storage, and soil moisture in the driest month of the growing period. Mean annual streamflow shows the lowest projected percent changes of all indicators. Among country groups, low income countries and lower middle income countries are most affected by decreased low flows and increased high flows, respectively, while high income countries are least affected by such changes. The incremental impact between 1.5 °C and 2 °C on high flows would be felt most by low income and lower middle income countries, the effect on soil moisture and low flows most by high income countries.

description: We study changes of the galactic cosmic ray (GCR) intensity for the ending period of the solar cycle 23 and the beginning of the solar cycle 24 using neutron monitors experimental data. We show that an increase of the GCR intensity in 2009 is generally related with decrease of the solar wind velocity U, the strength B of the interplanetary magnetic field (IMF), and the drift in negative (Aneg) polarity epoch. We present that temporal changes of rigidity dependence of the GCR intensity variation before reaching maximum level in 2009 and after it, do not noticeably differ from each other. The rigidity spectrum of the GCR intensity variations calculated based on neutron monitors data (for rigidities greaten than 10 GV) is hard in the minimum and near minimum epoch. We do not recognize any non-ordinary changes in the physical mechanism of modulation of the GCR intensity in the rigidity range of GCR particles to which neutron monitors respond. We compose 2-D non stationary model of transport equation to describe variations of the GCR intensity for 1996-2012 including the Apos (1996-2001) and the Aneg (2002-2012) periods; diffusion coefficient of cosmic rays for rigidity 10-15 GV is increased by 30 percent in 2009 (Aneg) comparing with 1996 (Apos). We believe that the proposed model is relatively realistic and obtained results are satisfactorily compatible with neutron monitors data.

A coherent structure approach for parameter estimation in Lagrangian Data Assimilation

description: We introduce a data assimilation method to estimate model parameters with observations of passive tracers by directly assimilating Lagrangian Coherent Structures. Our approach differs from the usual Lagrangian Data Assimilation approach, where parameters are estimated based on tracer trajectories. We employ the Approximate Bayesian Computation (ABC) framework to avoid computing the likelihood function of the coherent structure, which is usually unavailable. We solve the ABC by a Sequential Monte Carlo (SMC) method, and use Principal Component Analysis (PCA) to identify the coherent patterns from tracer trajectory data. Our new method shows remarkably improved results compared to the bootstrap particle filter when the physical model exhibits chaotic advection.
Retaining the past: Writer of fiction or historian?
Creators: name: Gadd, Bryan S
Publisher: name: CQUniversity
Year: 2023
Subjects: Creative writing (incl. scriptwriting)

description: Retaining the Past is a practice-based research project comprising a creative artefact, ‘The Clarity of Hindsight’, and an accompanying exegesis. The artefact aims to provide an authentic account of the social conditions of life in the late eighteenth century around provincial Oxfordshire, unfashionable Southwark and remote Cornwall. These accounts are based on sound historical research told not by way of conventional historical writing but via fictionalised, albeit ‘true-to-life’, stories of the lived experiences of the characters. ‘The Clarity of Hindsight’ demonstrates that sound historical research can be told imaginatively and legitimately as story, and the exegesis is my defence of that statement. The exegesis validates the artefact through two inter-related steps: an exploration of the creative mechanisms of the artefact itself and an overview of the landscape of historical fiction. It identifies the dangers and challenges of doing history through story, and offers some thoughts for potential future research.

description: We present results from a 244\,ks \textit{NuSTAR} observation of 3C\,273 obtained during a cross-calibration campaign with the \textit{Chandra}, \textit{INTEGRAL}, \textit{Suzaku}, \textit{Swift}, and \textit{XMM-Newton} observatories. We show that the spectrum, when fit with a power-law model using data from all observatories except \textit{INTEGRAL} over the 1--78\,keV band, leaves significant residuals in the \textit{NuSTAR} data between 30--78\,keV. The \nustar\ 3--78\,keV spectrum is well-described by an exponentially cutoff power-law ($Γ= 1.646 \pm 0.006$, E$_\mathrm{cutoff} = 202_{-34}^{+51}$\,keV) with a weak reflection component from cold, dense material. There is also evidence for a weak ($EW = 23 \pm 11$ eV) neutral iron line. We interpret these features as arising from coronal emission plus reflection off an accretion disk or distant material. Beyond 80\,keV \textit{INTEGRAL} data show clear excess flux relative to an extrapolation of the AGN model fit to \nustar. This high-energy power-law is consistent with the presence of a beamed jet, which begins to dominate over emission from the inner accretion flow at 30-40 keV. Modeling the jet locally (in the \textit{NuSTAR} + \textit{INTEGRAL} band) as a power-law, we find the coronal component is fit by $Γ_\mathrm{AGN} = 1.638 \pm 0.045$, $E_\mathrm{cutoff} = 47 \pm 15$\,keV, and jet photon index by $Γ_\mathrm{jet} = 1.05 \pm 0.4$. We also consider \textit{Fermi}/LAT observations of 3C\,273 and here the broad-band spectrum of the jet can be described by a log-parabolic model, peaking at $\sim 2$\,MeV. Finally, we investigate the spectral variability in the \textit{NuSTAR} band and find an inverse correlation between flux and $Γ$.

description: We present a simple analytical model and an exact numerical study which explain the role of roughness on different length scales for the fluid contact angle on rough solid surfaces. We show that there is no simple relation between the distribution of surface slopes and the fluid contact angle. In particular, surfaces with the same distribution of slopes may exhibit very different contact angles depending on the range of length-scales over which the surfaces have roughness.

The Jonkershoek Forestry Research Center (part of the former South African Forestry Research Institute) was established in 1935 at Jonkershoek, near Stellenbosch, under the directorship of Dr C. L. Wicht. The initial aim was to determine how forestry activities in state plantations would affect climate, water conservation and erosion, and was later expanded to include studies of fynbos ecology, fire and alien species. Studies from the 1930s to the early 1990s saw the accumulation of a large amount of data dealing with fire experiments, detailed vegetation plot surveys, rare plant surveys and ecological studies, hydrological studies and the development of management plans for catchments around the Western Cape. SAEON now houses the archive of data collected by the Jonkershoek Forestry Research Center, which was originally held by the Council for Scientific and Industrial Research (CSIR).

description: Technological advancements have revolutionized various aspects of human life, facilitating communication, business operations, healthcare, education, and environmental monitoring. However, this increased reliance on technology has also led to a surge in cybercrime, including cyber scams. The "419 scam" or Nigerian scam has been a persistent problem for decades, encompassing frauds like advance fee scams, fake lotteries, and black money scams. Initially prevalent through postal mail and later via fax, the scam has now transitioned to email. This study aims to identify recent types of 419 scam emails, particularly after the covid 19 pandemic, and explore commonly used email subjects. Analysis of the sample 419 scam emails revealed trending scams like lucky winner, threat of exposure, business/partnership proposals, investment, cancer/long-term illness, fund, and compensation scams. Emerging scams included COVID-related, cryptocurrency, marketing contact, and software development scams. Irrespective of the scam type, scammers commonly employed email subjects such as 'Re', 'Good day', 'Greetings', 'Dear friend', 'Confirm', 'Attention', and 'Hello dear'. The severity of cybercrime, especially the 419 scams, cannot be overstated, as it erodes trust, causes financial losses, and hampers Nigeria's reputation and economic progress. Combatting cyber scams and enhancing cybersecurity measures are crucial to protect individuals and organizations from falling victim to these fraudulent schemes.

description: After completing the experimental runs of a screening design, the responses under study are analyzed by statistical methods to detect the active effects. To increase the chances of correctly identifying these effects, a good analysis method should provide alternative interpretations of the data, reveal the aliasing present in the design, and search only meaningful sets of effects as defined by user-specified restrictions such as effect heredity. This article presents a mixed integer optimization strategy to analyze data from screening designs that possesses all these properties. We illustrate our method by analyzing data from real and synthetic experiments, and using simulations.
Edge structure of graphene monolayers in the ν = 0 quantum Hall state

description: Monolayer graphene at neutrality in the quantum Hall regime has many competing ground states with various types of ordering. The outcome of this competition is modified by the presence of the sample boundaries. In this paper we use a Hartree-Fock treatment of the electronic correlations allowing for space-dependent ordering. The edge influence is modeled by a simple perturbative effective magnetic field in valley space. We find that all phases found in the bulk of the sample, ferromagnetic, canted antiferromagnetic, charge-density wave and Kekul$é$ distortion are smoothly connected to a Kekul$é$-distorted edge. The single-particle excitations are computed taking into account the spatial variation of the order parameters. An eventual metal-insulator transition as a function of the Zeeman energy is not simply related to the type of bulk order.

description: We study the evolution of the one particle distribution function that solves exactly the relativistic Boltzmann equation within the relaxation time approximation for a conformal system undergoing simultaneously azimuthally symmetric transverse and boost-invariant longitudinal expansion. We show, for arbitrary values of the shear viscosity to entropy density ratio, that the distribution function can become negative in certain kinematic regions of the available phase space depending on the boundary conditions. For thermal equilibrium initial conditions, we determine numerically the physical boundary in phase space where the distribution function is always positive definite. The requirement of positivity of this particular exact solution restricts its domain of validity, and it imposes physical constraints on its applicability.

description: As second-generation gravitational-wave detectors prepare to analyze data at unprecedented sensitivity, there is great interest in searches for unmodeled transients, commonly called bursts. Significant effort has yielded a variety of techniques to identify and characterize such transient signals, and many of these methods have been applied to produce astrophysical results using data from first-generation detectors. However, the computational cost of background estimation remains a challenging problem; it is difficult to claim a 5σ detection with reasonable computational resources without paying for efficiency with reduced sensitivity. We demonstrate a hierarchical approach to gravitational-wave transient detection, focusing on long-lived signals, which can be used to detect transients with significance in excess of 5σ using modest computational resources. In particular, we show how previously developed seedless clustering techniques can be applied to large datasets to identify high-significance candidates without having to trade sensitivity for speed.

description: We explore the question of using an entangled state as a universal resource for implementing quantum measurements by local operations and classical communication (LOCC). We show that for most systems consisting of three or more subsystems, there is no entangled state from the same space that can enable all measurements by LOCC. This is in direct contrast to the bipartite case, where a maximally entangled state is an universal resource. Our results are obtained showing an equivalence between the problem of local state transformation and that of entanglement-assisted local unambiguous state discrimination.

description: MATSim is a traffic simulation software package which can be customized and extended in the Java programming language using a set of interfaces. It recently acquired a plug-in system which was implemented using framework-assisted dependency injection, a pattern more typically used in enterprise rather than research software. We describe the extension points and the implementation of the plug-in system. The architecture makes it easier and safer to combine independently developed components to complex simulation models, compared to many ad-hoc solutions often found in research software.

description: A spatial queue model in a multi-agent simulation framework is extended by introducing a more realistic behaviour, i.e. backward travelling holes. Space corresponding to a leaving vehicle is not available immediately on the upstream end of the link. Instead, the space travels backward with a constant speed. This space is named a ‘hole’. The resulting dynamics resemble Newell’s simplified kinematic wave model. Furthermore, fundamental diagrams from homogeneous and heterogeneous traffic simulations are presented. The sensitivity of the presented approach is tested with the help of flow density contours.

description: This is a scanned copy of the population dynamics of Protea cryophilla in the Cederberg State Forest, site 3219AC/4. The Jonkershoek Forestry Research Center (part of the former South African Forestry Research Institute) was established in 1935 at Jonkershoek, near Stellenbosch, under the directorship of Dr C. L. Wicht. The initial aim was to determine how forestry activities in state plantations would affect climate, water conservation and erosion, and was later expanded to include studies of fynbos ecology, fire and alien species.    Studies from the 1930s to the early 1990s saw the accumulation of a large amount of data dealing with fire experiments, detailed vegetation plot surveys, rare plant surveys and ecological studies, hydrological studies and the development of management plans for catchments around the Western Cape.

description: Dashboards are vital in modern business intelligence tools, providing non-technical users with an interface to access comprehensive business data. With the rise of cloud technology, there is an increased number of data sources to provide enriched contexts for various analytical tasks, leading to a demand for interactive dashboards over a large number of joins. Nevertheless, joins are among the most expensive operations in DBMSes, making the support of interactive dashboards over joins challenging. In this paper, we present Treant, a dashboard accelerator for queries over large joins. Treant uses factorized query execution to handle aggregation queries over large joins, which alone is still insufficient for interactive speeds. To address this, we exploit the incremental nature of user interactions using Calibrated Junction Hypertree (CJT), a novel data structure that applies lightweight materialization of the intermediates during factorized execution. CJT ensures that the work needed to compute a query is proportional to how different it is from the previous query, rather than the overall complexity. Treant manages CJTs to share work between queries and performs materialization offline or during user "think-times." Implemented as a middleware that rewrites SQL, Treant is portable to any SQL-based DBMS. Our experiments on single node and cloud DBMSes show that Treant improves dashboard interactions by two orders of magnitude, and provides 10x improvement for ML augmentation compared to SOTA factorized ML system.

Anharmonicity of multi–octupole-phonon excitations in Pb 208 : Analysis with multireference covariant density functional theory and subbarrier fusion of O 16 + Pb 208

description: We discuss anharmonicity of the multi-octupole-phonon states in $^{208}$Pb based on a covariant density functional theory, by fully taking into account the interplay between the quadrupole and the octupole degrees of freedom. Our results indicate the existence of a large anharmonicity in the transition strengths, even though the excitation energies are similar to those in the harmonic limit. We also show that the quadrupole-shape fluctuation significantly enhances the fragmentation of the two-octupole-phonon states in $^{208}$Pb. Using those transition strengths as inputs to coupled channels calculations, we then discuss the fusion reaction of $^{16}$O+$^{208}$Pb at energies around the Coulomb barrier. We show that the anharmonicity of the octupole vibrational excitation considerably improves previous coupled-channels calculations in the harmonic oscillator limit, significantly reducing the height of the main peak in the fusion barrier distribution.
Fine Tuning May Not Be Enough

description: We argue that the fine tuning problems of scalar-driven inflation may be worse than is commonly believed. The reason is that reheating requires the inflaton to be coupled to other matter fields whose vacuum fluctuations alter the inflaton potential. The usual response has been that even more fine-tuning of the classical potential $V(φ)$ can repair any damage done in this way. We point out that the effective potential in de Sitter background actually depends in a complicated way upon the dimensionless combination of $φ/H$. We also show that the factors of $H$ which occur in de Sitter do not even correspond to local functionals of the metric for general geometries, nor are they Planck-suppressed.

Socializing and emotional arousal : an analysis using biological signals and self-reported surveys

description: Emotions, and emotional responses, are fundamental to human growth and development. Considering how feeling both positively and negatively can lead to increased risk-taking behavior, it is important to consider the effects of friendship on emotional arousal. This study uses a novel technique of continuously measured electrodermal activity (EDA) signals, a sympathetic nervous system measure of emotional arousal, in conjunction with self-reported survey data to examine how social friendships impact emotional arousal. Furthermore, the study examines how socializing impacts positive and negative affect in self-reported social situations. Results show that socializing, in particular with groups of friends, results in more positive affect and is associated with increased emotional arousal, when compared to not socializing. The association is particularly salient when respondents also report feeling positive. This work makes a contribution to the emerging literature on how biosignal collection can be a way to distinctly measure the effects of social experiences on physical health.

description: Quantum spin models have been studied extensively in one and higher dimensions. Furthermore, these systems have been doped with holes to study $t$--$J$ models of $SU(2)$ spin-1/2. Their anyonic counterparts can be built from non-Abelian anyons, such as Fibonacci anyons described by $SU(2)_3$ theories, which are quantum deformations of the $SU(2)$ algebra. Inspired by the physics of $SU(2)$ spins, several works have explored ladders of Fibonacci anyons and also one-dimensional (1D) $t$--$J$ models. Here we aim to explore the combined effects of extended dimensionality and doping by studying ladders composed of coupled chains of interacting itinerant Fibonacci anyons. We show analytically that in the limit of strong rung couplings these models can be mapped onto effective 1D models. These effective models can either be gapped models of hole pairs, or gapless models described by $t$--$J$ (or modified $t$--$J$--$V$) chains of Fibonacci anyons, whose spectrum exhibits a fractionalization into charge and anyon degrees of freedom. By using exact diagonalizations for two-leg and three-leg ladders, we show that indeed the doped ladders show exactly the same behavior as that of $t$--$J$ chains. In the strong ferromagnetic rung limit, we can obtain a new model that hosts two different kinds of Fibonacci particles - which we denote as the heavy $τ$'s and light $τ$'s. These two particle types carry the same (non-Abelian) topological charge but different (Abelian) electric charges. Once again, we map the two-dimensional ladder onto an effective chain carrying these heavy and light $τ$'s. We perform a finite size scaling analysis to show the appearance of gapless modes for certain anyon densities whereas a topological gapped phase is suggested for another density regime.
