title: Measuring freedom, and its value
Creators: name: Cote, Nicolas
Publisher: name: London School of Economics and Political Science (LSE)
Year: 2021

description: This thesis concerns the measurement of freedom, and its value. Specifically, I am concerned with three overarching questions. First, can we measure the extent of an individual’s freedom? It had better be that we can, otherwise much ordinary and intuitive talk that we would like to vindicate – say, about free persons being freer than slaves – will turn out to be false or meaningless. Second, in what ways is freedom valuable, and how is this value measured? It matters, for example, whether freedom is valuable only insofar as it enables us to pursue specific ends we happen to value for independent reasons, or whether it is also valuable in itself. In the latter case, but not the former, more freedom will always (other things being equal) be better. Likewise, it’s important to get clarity on what ends, exactly, freedom is especially instrumentally valuable in promoting, since this goes to how much we should care about it. And finally, the liberal political tradition asserts that there is a special sphere of personal choices within which individuals should be free to do as they please, for reasons over and above the value of freedom itself. Now, can we measure the extent to which states and individuals respect individual liberties, and can we weigh the importance of respecting liberty against competing values like social welfare? To answer these questions, I follow the axiomatic tradition of social choice theory, and I develop several novel measures of freedom – including the first measure of freedom ever proposed that is sensitive to how modally robustly our options are available – a novel approach to measuring the diversity of an opportunity set, and I develop an account of the value of freedom according to which an important part of why freedom matters is that it enables us to improve our preferences through learning, and I construct ways of measuring the value of freedom along this dimension of value. Finally, in later chapters, I provide a representation result for a measure of illiberalism, i.e. of the degree to which states fail to respect the rights of their citizens, and I extend this result to provide a characterization of moral theories that express concern for respecting the rights of others. The final chapter closes by discussing how this concern may be weighed against concerns for social welfare.

description: The first eurypterid known from Italy is described, as Adelophthalmus piussii n. sp. It comes from the Upper Carboniferous of the Carnic Alps (Friuli, NE Italy). Relationships with related species are discussed. Adelophthalmids are the commonest eurypterids of the late Palaeozoic, at which time the disparity of the order was waning. The new record enhances our knowledge of adelophthalmid distribution and diversity.

description: Thermodynamics of a heavy quark-antiquark pair in SU(3)-QCD is studied below the deconfinement critical temperature, $T_c$. In the quenched case, a model of the string passing through heavy valence gluons yields a correct estimate of $T_c$ and a behavior of the string tension near $T_c$. For two light flavors, entropy and internal energy can be obtained from the partition function of heavy-light mesons and baryons. They are in a good qualitative agreement with the lattice results.

description: Let $X$ be a set and $\mathcal{T}_X$ be the full transformation semigroup on $X$. For a partition $\mathcal{P}$ of $X$, we consider semigroups $T(X, \mathcal{P}) = \{f\in \mathcal{T}_X| (\forall X_i\in \mathcal{P}) (\exists X_j \in \mathcal{P})\;X_i f \subseteq X_j\}$, $Σ(X, \mathcal{P}) = \{f\in T(X, \mathcal{P})|(\forall X_i \in \mathcal{P})\; Xf \cap X_i \neq \emptyset\}$, and $Γ(X, \mathcal{P}) = \{f\in \mathcal{T}_X|(\forall X_i\in \mathcal{P})(\exists X_j\in \mathcal{P})\; X_i f = X_j\}$. We characterize unit-regular elements of both $T(X, \mathcal{P})$ and $Σ(X, \mathcal{P})$ for finite $X$. We discuss set inclusion between $Γ(X, \mathcal{P})$ and certain semigroups of transformations preserving $\mathcal{P}$. We characterize and count regular elements and idempotents of $Γ(X, \mathcal{P})$. For finite $X$, we prove that every regular element of $Γ(X, \mathcal{P})$ is unit-regular and also calculate the size of $Γ(X, \mathcal{P})$.

It allows automated computations of both cut-constructible {\it and} rational parts of one-loop scattering amplitudes from on-shell tree amplitudes. We illustrate the method by (re)-computing all four-, five- and six-gluon scattering amplitudes in QCD at one-loop.

description: The Batain Group of the northeastern coastal plain of Oman consists of offshore and deeper water deposits that accumulated in the Batain Basin and which were subsequently obducted onto the eastern margin of Oman. The oldest deposits of the Batain Group are the marly limestones of the Qarari Unit that have been dated as Early to Late Permian or Murgabian by different workers. Recently discovered outcrops of the Qarari Unit from the northern Batain plain are richly fossiliferous including the occurrence of fusulinids in three separate outcrops. The fusulinids represented are two species of Skinnerella - a subgenus of Parafusulina: Parafusulina (Skinnerella) visseri Reichel and the new taxon P. (S.) arabica. The most likely age of the described fusulinids is estimated as Kubergandian. The major marine transgression of the Tethyan realm that began in the Yakhtashian-Bolorian appears to have begun earlier in the Batain Basin than in other parts of Arabia and the Gulf, where it is represented by the Khuff Formation of Murgabian-Dorashamian age.

description: Nearly 500 cluster candidates have been reported by searches based on the new all-sky near infrared surveys. The true nature of the majority of these objects is still unknown. This project aims to estimate the physical parameters of some of the candidates in order to use them as probes of the obscured star formation in the Milky Way. Here we report deep near infrared observations of four objects, discovered by our search based on the 2MASS Point Source Catalog (Ivanov et al. 2002; Borissova et al. 2003). CC04 appears to be a few million year old cluster. We estimate its distance and extinction, and set a limit on the total mass. CC08 contains red supergiants, indicating a slightly older age of about 7-10 Myr. The suspected cluster nature of CC13 was not confirmed. CC14 appears to be an interesting candidate with double-tail-like morphology but our data doesn't allow us to derive a firm conclusion about the nature of this object. We found no supermassive star clusters similar to the Arches or the Quintuplet (Mtot >= 10**4 Msolar) among the dozen confirmed clusters studied so far in this series of papers, indicating that such objects are not common in the Milky Way.

An optically thick inner corona geometry for the Very High State Galactic Black Hole XTE J1550-564

Subjects: subject: Astrophysics (astro-ph)

description: (truncated version) The X-ray spectra of Galactic binary systems in the very high state show both strong disk emission and a strong, steep tail to high energies. We use simultaneous optical-ASCA-RXTE data from the black hole transient XTE J1550-564 as a specific example, and show that these have disc spectra which are significantly lower in temperature than those seen from the same source at the same luminosity when in the disc dominated state. If these give a true picture of the disc then either the disc emissivity has reduced, and/or the disc truncates above the last stable orbit. However, it is often assumed that the tail is produced by Compton scattering, in which case its shape in these spectra requires that the Comptonising region is marginally optically thick (tau~2-3), and covers a large fraction of the inner disc. This will distort our view of the disc. We build a theoretical model of a Comptonising corona over an inner disc, and fit this to the data, but find that it still requires a large increase in inner disc radius for a standard disc emissivity. Instead it seems more probable that the disc emissivity changes in the presence of the corona. We implement the specific inner disc-corona coupling model of Svensson & Zdziarski (1994) and show that this can explain the low temperature/high luminosity disc emission seen in the very high state with only a small increase in radius of the disc. While this inferred disc truncation is probably not significant given the model uncertainties, it is consistent with the low frequency QPO and gives continuity of properties with the low/hard state spectra.

description: Extant research on the gender pay gap suggests men and women who do the same work for the same employer receive similar pay, so that processes sorting people into jobs are thought to account for the vast majority of the pay gap. Data that can identify women and men who do the same work for the same employer are rare, and research informing this crucial aspect of gender differences in pay is several decades old and from a limited number of countries. Using recent linked employer-employee data from 15 countries, this study shows that the processes sorting people into different jobs account for substantially less of the gender pay differences than was previously believed and that within-job pay differences remain consequential.

description: Ammonites and belemnites from a Middle Jurassic section at Telma-Dareh (Alborz Mountains, northern Iran) are described. The lithology of the studied section consists of an alternation of marls and limestones attributed to the Dalichai Fm., overlying the top of the Shemshak Fm. (sandstones) and underlying the Lar Fm. (limestones). Fossils are rather abundant but concentrated in ten scattered levels, ranging from the Aalenian (Scissum-Murchisonae zones) up to the Bajocian. Ammonites (Tmetoceras scissum, Leioceras cf. comptum, Ludwigia cf. murchisonae, Onychoceras ? sp., and Leptosphinctes sp.), belemnites (Brevibelus breviformis, Holcobelus cf. munieri ) and bivalves are the most abundant and well-preserved fossils; accessory elements are scarce brachiopods and gastropods. The palaeobiogeographic affinities of the belemnite fauna is Subboreal-Submediterranean, whereas the ammonites have Submediterranean-Tethyan affinities. The Aalenian age of the lower part of the Dalichai Fm. at Telma-Dareh differs from the Bajocian age attributed by other authors to this formation in other localities.

Is world politics returning to the Middle Ages?: the new medievalism and the problems of authority and change in international relations theory
Creators: name: Fabry, Mikulas
Publisher: name: University of British Columbia
Year: 2009

description: The topic of international change is one of the most elusive areas of inquiry in the field of IR. While it would be hard to find in academic texts a more frequently used term than "change," the fact is that our grasp of the subject remains weak. There is no consensus among IR scholars either on the most appropriate approach to study international change or on the best way to differentiate between its various types. This thesis seeks to contribute to our understanding of international change by exploring theoretically the problem of the most basic possible change - the process of replacement of a multi-unit system by a different kind of multi-unit system. Specifically, it examines the claims that the contemporary international system is in the midst of transformation, the results of which are in many crucial respects reminiscent of the way politics was conducted or structured in the Middle Ages. Political authority is said to be shifting from the state to other international actors and the emerging order can be likened to the medieval system of overlapping authority. The following study shows that upon close inspection the idea of new medievalism cannot stand. Its central claim is that system transformations are legal revolutions in which one fundamental constitutive principle is being replaced by another. This principle specifies the manner in which political authority is distributed across the system. Political authority is above all a legal notion and the proper approach for investigating its fundamental change is jurisprudential. Analyzing the international society of states as a legal order requires us to look at the viability of its fundamental constitutive principle, sovereignty. There are at present no signs that would indicate it is being replaced. The neo-medievalists mistake political authority with power of performance and this leads them to faulty conclusions.

description: We present compelling observational evidence of G133.50+9.01 being a bona fide cloud-cloud collision candidate with signatures of induced filament, core, and cluster formation. The CO molecular line observations reveal that the G133.50+9.01 complex is made of two colliding molecular clouds with systemic velocities, -16.9 km s-1 and -14.1 km s-1. The intersection of the clouds is characterised by broad bridging features characteristic of collision. The morphology of the shocked layer at the interaction front resembles an arc like structure with enhanced excitation temperature and H2 column density. A complex network of filaments is detected in the SCUBA 850 μm image with 14 embedded dense cores, all well correlated spatially with the shocked layer. A stellar cluster revealed through an over-density of identified Class I and II young stellar objects is found located along the arc in the intersection region corroborating with a likely collision induced origin.

description: Objective: To determine the prevalence of anemia among children aged 12 years and less in the Saudi population

Methods: This study employs a cross-sectional design to assess the prevalence of anemia and its associated factors among children aged 12 years or less in the Kingdom of Saudi Arabia (KSA). A cross-sectional approach allows for the collection of data at a single point in time from a diverse group of participants.

Results: The study included 587 participants. The most frequent gender among them was Male (n= 316, 53.8%) followed by Female (n= 271, 46%). The most frequent BMI among study participants was normal 5-85 kg/m2 (n= 570, 97.1%), followed by obese more than 95 kg/m2 (n= 15, 2.6%). The most frequent age value among study participants was 4-6 years (n= 296, 50%) followed by 10-12 years (n= 166, 28%). The most frequent anemia level among them was non-anemia (n= 308, 52%), followed by Moderate anemia (n= 126, 21%). Participants were asked about their parents' educational level. The most frequent education for fathers among study participants was university (n= 395, 67.3%), followed by school (n= 159, 27.1%). The most frequent education for mothers among study participants was university (n= 383, 65.2%), followed by school (n= 144, 24.5%). Participants were asked about their eating if they eat red meat; the most frequent answer was yes (n= 380, 64.7%); other hands answered no (n= 207, 35.3%), and about eating green vegetables, yes (n=267, 45.5%), in other hands no (n=320, 54.5%). The eating citrus consumption the most answered yes (n=345, 58.8%), followed by no (242, 41.2%). The most frequently were not exposed to smoking (n=454, 77.3%), exposed to smoking (n=133, 22.6%).

Conclusion: The results of the study showed that most of the children are male and the most of there weight was normal according to their BMI. Most of them were children of university-educated fathers and mothers. Most children have not been exposed to smoking. Most of them relied on eating red meat and Citrus consumption, in addition to drinking milk. Most study participants had good communication.

description: Maximally entangled states are of utmost importance to quantum communication, dense coding, and quantum teleportation. With a trapped ion placed inside a high finesse optical cavity, interacting with field of an external laser and quantized cavity field, a scheme to generate a maximally entangled three qubit GHZ state, is proposed. The dynamics of tripartite entanglement is investigated, using negativity as an entanglement measure and linear entropy as a measure of mixedness of a state. It is found that (a) the number of modes available to the subsystem determines the maximum entanglement of a subsystem, b) at entanglement maxima and minima, linear entropy and negativity uniquely determine the nature of state, but the two measures do not induce the same ordering of states, and c) for a special choice of system parameters maximally entangled tripartite two mode GHZ state is generated. The scheme presented for GHZ state generation is a single step process and is reduction free. PACS: 03.67.-a, 42.50.-p, 03.67.Dd

description: We present new elemental abundance studies of seven damped Lyman-alpha systems (DLAs). Together with the four DLAs analyzed in Dessauges-Zavadsky et al. (2004), we have a sample of eleven DLA galaxies with uniquely comprehensive and homogeneous abundance measurements. These observations allow one to study the abundance patterns of 22 elements and the chemical variations in the interstellar medium of galaxies outside the Local Group. Comparing the gas-phase abundance ratios of these high redshift galaxies, we found that they show low RMS dispersions, reaching only up 2-3 times the statistical errors for the majority of elements. This uniformity is remarkable given that the quasar sightlines cross gaseous regions with HI column densities spanning over one order of magnitude and metallicities ranging from 1/55 to 1/5 solar. The gas-phase abundance patterns of interstellar medium clouds within the DLA galaxies detected along the velocity profiles show, on the other hand, a high dispersion in several abundance ratios, indicating that chemical variations seem to be more confined to individual clouds within the DLA galaxies than to integrated profiles. The analysis of the cloud-to-cloud chemical variations within seven individual DLAs reveals that five of them show statistically significant variations, higher than 0.2 dex at more than 3 sigma. The sources of these variations are both the differential dust depletion and/or ionization effects; however, no evidence for variations due to different star formation histories could be highlighted. These observations place large constraints on the mixing timescales of protogalaxies and on scenarios of galaxy formation within the CDM hierarchical theory. Finally, we provide an astrophysical determination of the oscillator strength of the NiII 1317 transition.

We develop an analog of the Liouville loop perturbation theory, which allows us to quantitatively study the generating functional for an arbitrary smooth metric and an inhomogeneous magnetic field beyond the leading orders in large $N$.

We present results based on the spatial offsets between the emission-line regions and stellar continua in ELGs from two z$\sim$0.25 galaxy clusters, Abell 2390 and Abell 2465. We find a preference in the offsets being pointed away from the cluster center. Combining the two clusters, there is a 3$σ$ excess for high-velocity galaxies within the virial radius having the offsets to be pointed away from the cluster center. Assuming the offset being a proxy for the velocity vector of a galaxy, as expected from ram pressure stripping, this excess indicates that ram pressure stripping occurs most effectively during the first passage of an infalling galaxy, leading to the quenching of its star formation. We also find that, outside the virial region, the continuum-normalized H$α$ line flux for infalling galaxies with large offsets are on average lower than those with small or no measurable offset, further supporting ram pressure as a dominant quenching mechanism during the initial infall stages.

description: We present models of turbulent mixing at the boundaries between hot (T~10^{6-7} K) and warm material (T~10^4 K) in the interstellar medium, using a three-dimensional magnetohydrodynamical code, with radiative cooling. The source of turbulence in our simulations is a Kelvin-Helmholtz instability, produced by shear between the two media. We found, that because the growth rate of the large scale modes in the instability is rather slow, it takes a significant amount of time (~1 Myr) for turbulence to produce effective mixing. We find that the total column densities of the highly ionized species (C IV, N V, and O VI) per interface (assuming ionization equilibrium) are similar to previous steady-state non-equilibrium ionization models, but grow slowly from log N ~10^{11} to a few 10^{12} cm^{-2} as the interface evolves. However, the column density ratios can differ significantly from previous estimates, with an order of magnitude variation in N(C IV)/N(O VI) as the mixing develops.

description: Planners using accurate models can be effective for accomplishing manipulation tasks in the real world, but are typically highly specialized and require significant fine-tuning to be reliable. Meanwhile, learning is useful for adaptation, but can require a substantial amount of data collection. In this paper, we propose a method that improves the efficiency of sub-optimal planners with approximate but simple and fast models by switching to a model-free policy when unexpected transitions are observed. Unlike previous work, our method specifically addresses when the planner fails due to transition model error by patching with a local policy only where needed. First, we use a sub-optimal model-based planner to perform a task until model failure is detected. Next, we learn a local model-free policy from expert demonstrations to complete the task in regions where the model failed. To show the efficacy of our method, we perform experiments with a shape insertion puzzle and compare our results to both pure planning and imitation learning approaches. We then apply our method to a door opening task. Our experiments demonstrate that our patch-enhanced planner performs more reliably than pure planning and with lower overall sample complexity than pure imitation learning.

A Methodology for the Quantitative Assessment of the Aircraft Systems Accessibility

description: A reduction of the maintenance effort of commercial aircrafts caused by changes in the sys- tem architecture results in the opportunity to decrease the direct operating costs. At the Institute of Aerospace Systems, the integration of maintenance aspects into the preliminary aircraft design is being researched within the framework of the AGILE 4.0 project. Thereby, the accessibility of on-board systems and their components significantly influences the maintainability of commercial aircrafts. In this thesis, a methodology to quantitatively evaluate the accessibility of aircraft systems is developed. With the self-developed methodology 14 different system properties that influence maintainability are evaluated on a detailed scoring scale, in order to allow gradation between the lowest and highest score. Additionally, there exists the option to use weighting factors to allow different properties or components to have a higher influence on the overall result. To validate the developed methodology, the established maintainability prediction methodology Procedure III, which is published in Handbook 472 of the US military, is also implemented. Both methodologies are applied to a reference system, which corresponds to a part of the hydraulic system of a Boeing 777. The results of this work show that the self-developed methodology provides a more accurate assessment of the maintainability. In addition, it also takes into account the trade-off between opposing system properties. One example is the restricted installation space, which is in con- flict with an increased space between components. Further, the system layout of the reference system is optimized with regard to the maintainability prediction of both methodologies. Here, the advantages of the self-developed methodology also become clear, since a greater improvement in accessibility is achieved, compared to an optimization regarding Procedure III. The weighting factors implemented in the self-developed methodology also allow to target the improvement of certain system properties. Similarly, the component-based weighting can be used to specifically optimize the maintainability of components with higher failure rates.

description: Context: The calibration of binary systems with accurately known masses and/or radii provides powerful tools to test stellar structure and evolution theory and to determine the age and helium content of stars. We study the eclipsing double-lined spectroscopic binary system RS Cha, for which we have accurate observations of the parameters of both stars (masses, radii, luminosities, effective temperatures and metallicity). Aims: We have calculated several sets of stellar models for the components of the RS Cha system, with the aim of reproducing simultaneously the available observational constraints and to estimate the age and initial helium abundance of the system. Methods: Using the CESAM stellar evolution code, we model both components starting from the initial mass and metallicity and adjusting the input parameters and physics in order to satisfy the observational constraints. Results: We find that the observations cannot be reproduced if we assume that the abundance ratios are solar but they are satisfied if carbon and nitrogen are depleted in the RS Cha system with respect to the Sun. This is in accordance with the abundances observed in other young stars. The RS Cha system is in an evolutionary stage at the end of the PMS phase where models are not strongly sensitive to various physical uncertainties. However we show that the oscillations of these two stars, which have been detected, would be able to discriminate between different options in the physical description of this evolutionary phase.

description: We present 3D core-collapse supernova simulations of massive Pop-III progenitor stars at the transition to the pulsational pair instability regime. We simulate two progenitor models with initial masses of $85\,\mathrm{M}_{\odot}$ and $100\,\mathrm{M}_\odot$ with the LS220, SFHo, and SFHx equations of state. The $85\,\mathrm{M}_{\odot}$ progenitor experiences a pair instability pulse coincident with core collapse, whereas the $100\,\mathrm{M}_{\odot}$ progenitor has already gone through a sequence of four pulses $1\mathord,500$ years before collapse in which it ejected its H and He envelope. The $85\,\mathrm{M}_{\odot}$ models experience shock revival and then delayed collapse to a black hole (BH) due to ongoing accretion within hundreds of milliseconds. The diagnostic energy of the incipient explosion reaches up to $2.7\times10^{51}\,\mathrm{erg}$ in the SFHx model. Due to the high binding energy of the metal core, BH collapse by fallback is eventually unavoidable, but partial mass ejection may be possible. The $100\,\mathrm{M}_\odot$ models have not achieved shock revival or undergone BH collapse by the end of the simulation. All models exhibit relatively strong gravitational-wave emission both in the high-frequency g-mode emission band and at low frequencies. The SFHx and SFHo models show clear emission from the standing accretion shock instability. For our models, we estimate maximum detection distances of up to $\mathord{\sim}46\,\mathrm{kpc}$ with LIGO and $\mathord{\sim} 850\,\mathrm{kpc}$ with Cosmic Explorer.

description: The triangular enhancement of the rapidity distribution of hadrons produced in p+A reactions relative to p+p is a leading order in A^{1/3}/log(s) violation of longitudinal boost invariance at high energies. In A+A reactions this leads to a trapezoidal enhancement of the local rapidity density of produced gluons. The local rapidity gradient is proportional to the local participant number asymmetry, and leads to an effective rotation in the reaction plane. We propose that three dimensional jet tomography, correlating the long range rapidity and azimuthal dependences of the nuclear modification factor, R_{AA}(η,ϕ,p_\perp; b>0), can be used to look for this intrinsic longitudinal boost violating structure of $A+A$ collisions to image the produced twisted strongly coupled quark gluon plasma (sQGP). In addition to dipole and elliptic azimuthal moments of R_{AA}, a significant high p_\perp octupole moment is predicted away from midrapidity. The azimuthal angles of maximal opacity and hence minima of R_{AA} are rotated away from the normal to the reaction plane by an `Octupole Twist' angle, θ_3(η), at forward rapidities.

description: The q-character is a strong tool to study finite-dimensional representations of quantum affine algebras. However, the explicit formula of the q-character of a given representation has not been known so far. Frenkel and Mukhin proposed the iterative algorithm which generates the q-character of a given irreducible representation starting from its highest weight monomial. The algorithm is known to work for various classes of representations. In this note, however, we give an example in which the algorithm fails to generate the q-character.

description: Large volumes of CCD imaging data that will become available from wide-field cameras at telescopes such as the CFHT, SUBARU, VST, or VISTA in the near future are highly suitable for systematic distance surveys of early-type galaxies using the Surface Brightness Fluctuation (SBF) method. For the efficient processing of such large data sets, we are developing the first semi-automatic SBF analysis pipeline named SAPAC. After a brief description of the SBF method we discuss the image quality needed for a successful distance measurement and give some background information on SAPAC

description: На примере жанра повести раскрываются основные стилевые трансформации русской и белорусской модернистской прозы второй половины ХХ века. Обращение к эстетике модернизма и авангарда, совмещение сентиментального и физиологического, реальности и фантастики, использование приемов вторичной художественной условности позволили писателям отразить сложные и неоднозначные отношения человека с окружающей действительностью, попытку сориентироваться в условиях социальной деконструкции. В работе анализируются причины и национальная специфика дискретного развития модернизма в русской и белорусской литературах ХХ века. Сопоставительный ракурс исследования позволяет сделать вывод о взаимосвязях близкородственных литератур, их общих и особых чертах в отражении мира и человека.
