Divine and sublime creativity : a comparison of Schenkerian and Ciceronian principles
Creators: name: Mansoori-Dara, Reva
Publisher: name: University of British Columbia
Year: 2009

description: As is clear from the title, this thesis presents a comparison of Schenkerian and Ciceronian principles. The thesis will focus mainly on the characteristics of the creative process essential for producing a sublime and intellectual work. Admittedly comparing a Roman lawyer/philosopher (Cicero) to a 20th century musician/theorist (Schenker) will bring forth many obstacles and will suffer from numerous imperfections. Stressing the commonalties between two men of time frames too far apart is an arduous task. I found it most helpful to go about this problem through three stages: first, by presenting an overview of the lives, historical circumstances, and careers of the two mentioned figures; second, by presenting a basic comparison of the two branches of thought; and third, by dealing with some of the more complicated philosophical issues for a better understanding of the two doctrines. Since many of the Schenkerian and Ciceronian principles are heavily rooted in Platonism, an overview of Plato's theory of 'forms and ideas' is presented to guide the reader toward a better grasp of the concepts. The reader may, however, be uncertain regarding the objective of this thesis: is this a comparison of the two philosophies or an evaluation of them? Of course, in order to achieve a satisfactory comparison, one must first understand the two philosophies; this demands an explicit analysis which, in my view, is a form of evaluation. I have also shown and questioned some of the ambiguities of the two philosophies without offering any solutions. This will perhaps help the reader to understand the path I had to take in completing this thesis. I have included these philosophical remarks in the endnotes. Furthermore, Schenkerian philosophy reveals many other important influences other than Platonism; although not the focus of this thesis, numerous references to great thinkers such as Nietzsche, Spinoza, Hanslick, and Freud illustrate this point. Much of the presented bibliographical material on the life of Cicero can be found in the On the Commonwealth and On the Laws. Furthermore, Michael B. Fuster's Masters of Political Thought has been used as a source of reference for a great portion of the philosophical interpretations. Much of what I have presented on Schenker and Schenkerian literature has been gathered through my studies and conversations with Dr. Benjamin, my advisor: the most reliable source with whom I am acquainted. This is perhaps the reason for not including any other philosophical writings on Schenkerian literature in the bibliography.

description: The mixed spin-1/2 and spin-3/2 Ising model on the extended Kagomé lattice is solved by establishing a mapping correspondence with the eight-vertex model. Letting the parameter of uniaxial single-ion anisotropy tend to infinity, the model becomes exactly soluble as a free-fermion eight-vertex model. Under this restriction, the critical points are characterized by critical exponents from the standard Ising universality class. In a certain subspace of interaction parameters that corresponds to a coexistence surface between two ordered phases, the model becomes exactly soluble as a symmetric zero-field eight-vertex model. This surface is bounded by a line of bicritical points that have non-universal interaction-dependent critical exponents.

description: A hybrid approach to estimate the asymmetric price transmission between the farm gate and the retail market is proposed. The model is estimated for the fluid milk market of the Northeast U.S., that of the metropolitan area of New York City as well as that of Upstate New York. Spatially disaggregated data allows the impact of regional dairy regulation on the farm-retail price spread to be assessed, as well as the behavior of the middlemen regarding price transmission on markets with different levels of retail concentration to be estimated. Results suggest that intermediaries transmit variations in milk farm price in an asymmetric way in the short-run; that governmental intervention might force middlemen to act competitively in terms of price transmission; and that a high degree of concentration at the retail level is not synonymous with inefficient price transmission.

description: Baggrund: Demenssygdom har store konsekvenser for mennesker med demens, og uden helbredende behandling forsøges en række tiltag, herunder brugen af neuropædagogik, til at forstå mennesker med demens. Yderligere er der en stigende forskningsinteresse inden for begrebsrammen Fundamentals of Care (FoC) og demens, men det er uudforsket, hvordan neuropædagogik og FoC kan bidrage til demensområdet. Formål: Artiklens formål er at reflektere over, om og hvordan neuropædagogik og begrebsrammen FoC kan bidrage til at kvalificere sygeplejen til mennesker med demens. Design og metode: Denne artikel tager udgangspunkt i en case om Johanne, som har demens. Der reflekteres over casen i forhold til litteratur om neuropædagogik og FoC. Resultat: Neuropædagogik og FoC kan bidrage til en mere holistisk forståelse for mennesker med demens og medarbejdernes ansvar ift. etablering og vedligeholdelse af en relation. Ved hjælp af neuropædagogikken fokuseres bl.a. på relationen, livskvalitet og læring, hvor sygeplejen ud fra FoC rummer den kompleksitet, det er at opfylde patienters behov. Kvalificering af sygeplejen vil afhænge af medarbejdere, ledelse og de ydre rammer. Konklusion: Ved at fokusere på både neuropædagogik og FoC kan det ud fra et teoretisk perspektiv være muligt at opnå en større forståelse for mennesker med demens og dermed yde en mere kvalificeret pleje og omsorg. Perspektivering: Der er behov for empirisk at undersøge, om man opnår en kvalificeret pleje og omsorg for mennesker med demens ved at anvende et neuropædagogisk perspektiv og begrebsrammen FoC i praksis.

description: Scale interactions in Hall MHD are studied using both the mean field theory derivation of transport coefficients, and direct numerical simulations in three space dimensions. In the magnetically dominated regime, the eddy resistivity is found to be negative definite, leading to large scale instabilities. A direct cascade of the total energy is observed, although as the amplitude of the Hall effect is increased, backscatter of magnetic energy to large scales is found, a feature not present in MHD flows. The coupling between the magnetic and velocity fields is different than in the MHD case, and backscatter of energy from small scale magnetic fields to large scale flows is also observed. For the magnetic helicity, a strong quenching of its transfer is found. We also discuss non-helical magnetically forced Hall-MHD simulations where growth of a large scale magnetic field is observed.

description: Gamma Doradus stars present an incredibly rich pulsation spectra, with gravito-inertial modes, in some cases supplemented with delta Scuti-like pressure modes and in numerous cases with Rossby modes. The present paper aims at showing that, in addition to these modes established in the radiative envelope, pure inertial modes, trapped in the convective core, can be detected in Kepler observations of gamma Doradus stars, thanks to their resonance with the gravito-inertial modes. We start by using a simplified model of perturbations in a full sphere of uniform density. Under these conditions, the spectrum of pure inertial modes is known from analytical solutions of the so-called Poincare equation. We then compute coupling factors which help select the pure inertial modes which interact best with the surrounding dipolar gravito-inertial modes. Using complete calculations of gravito-inertial modes in realistic models of gamma Doradus stars, we are able to show that the pure inertial/gravito-inertial resonances appear as dips in the gravito-inertial mode period spacing series at spin parameters close to those predicted by the simple model. We find the first evidence of such dips in the Kepler gamma Doradus star KIC5608334. Finally, using complete calculations in isolated convective cores, we find that the spin parameters of the pure inertial/gravito-inertial resonances are also sensitive to the density stratification of the convective core. In conclusion, we have discovered that certain dips in gravito-inertial mode period spacings observed in some Kepler stars are in fact the signatures of resonances with pure-inertial modes that are trapped in the convective core. This holds the promise to finally access the central conditions , i.e. rotation and density stratification, of intermediate-mass stars on the main sequence.

description: I 2013 påbegyndte Morsø Kommune en særlig indsats for at gøre pædagogiske dagtilbud bekendt med neuropsykologien, og her fik pædagogisk personale gennem kurser bl.a. kendskab til hjernens negative effekter ved overproduktion af stresshormoner, og hvordan disse er skadelige for børn. Som følge heraf har jeg i 2017 gennemført et casestudie baseret på følgende problemformulering: Hvilken indsats gør medarbejdere i pædagogiske dagtilbud for at forstå og forebygge stress blandt 0-6-årige børn? I alt deltog 50 % af Morsø Kommunes kommunale dagtilbud i fokusgruppeinterview. Undersøgelsens data er bearbejdet ud fra en meningskodning, meningskondensering samt meningsfortolkning og analyseres ved hjælp af de neuroaffektive kompasser (Hart, 2006). Resultaterne viser, at alle deltagende dagtilbud oplever børn, der i dagligdagen viser tegn på at være stressede, og at institutionerne overvejende benytter sig af anerkendende tilgange (Honneth, 2008) til at arbejde med stress i praksis.

description: This paper provides an overview of recent research on estimating competitive interaction in food product categories. In particular, the focus of this review is on research using scanner data conducted at the disaggregate (e.g., store, chain or local market) level, including empirical studies of vertical (i.e., within-channel) conduct. Studies addressing the competitive interaction on price, as well as non-price variables (e.g., in-store display and feature advertising) are considered. The author first describes the methodologies available for measuring the competitive interaction between firms and then briefly summarizes recent empirical developments. Given the complexity of the interactions that take place in practice, it is argued that much of the richness of actual competitive behavior is lost in aggregate analysis. Competitive interaction is the result of a complex set of variables and influences-demand side factors, market and industry structure, firm "personality", and category characteristics all interact in a complex fashion to determine strategic behavior of retailers and manufacturers.
Non-adiabatic molecular quantum dynamics with quantum computers

description: The theoretical investigation of non-adiabatic processes is hampered by the complexity of the coupled electron-nuclear dynamics beyond the Born-Oppenheimer approximation. Classically, the simulation of such reactions is limited by the unfavourable scaling of the computational resources as a function of the system size. While quantum computing exhibits proven quantum advantage for the simulation of real-time dynamics, the study of quantum algorithms for the description of non-adiabatic phenomena is still unexplored. In this work, we propose a quantum algorithm for the simulation of fast non-adiabatic chemical processes together with an initialization scheme for quantum hardware calculations. In particular, we introduce a first-quantization method for the time evolution of a wavepacket on two coupled harmonic potential energy surfaces (Marcus model). In our approach, the computational resources scale polynomially in the system dimensions, opening up new avenues for the study of photophysical processes that are classically intractable.

description: We discuss various definitions of decoherence and how it can be measured. We compare and contrast decoherence in quantum systems with an infinite number of eigenstates (such as the free particle and the oscillator) and spin systems. In the former case, we point out the essential difference between assuming "entanglement at all times" and entanglement with the reservoir occuring at some initial time. We also discuss optimum calculational techniques in both arenas.

Dark Energy: The Observational Challenge
Creators: name: Weinberg, David H.
Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Nearly all proposed tests for the nature of dark energy measure some combination of four fundamental observables: the Hubble parameter H(z), the distance-redshift relation d(z), the age-redshift relation t(z), or the linear growth factor D_1(z). I discuss the sensitivity of these observables to the value and redshift history of the equation of state parameter w, emphasizing where these different observables are and are not complementary. Demonstrating time-variability of w is difficult in most cases because dark energy is dynamically insignificant at high redshift. Time-variability in which dark energy tracks the matter density at high redshift and changes to a cosmological constant at low redshift is {\it relatively} easy to detect. However, even a sharp transition of this sort at z_c=1 produces only percent-level differences in d(z) or D_1(z) over the redshift range 0.4 < z < 1.8$, relative to the closest constant-w model. Estimates of D_1(z) or H(z) at higher redshift, potentially achievable with the Ly-alpha forest, galaxy redshift surveys, and the CMB power spectrum, can add substantial leverage on such models, given precise distance constraints at z < 2. The most promising routes to obtaining sub-percent precision on dark energy observables are space-based studies of Type Ia supernovae, which measure d(z) directly, and of weak gravitational lensing, which is sensitive to d(z), D_1(z), and H(z).

description: This paper investigates the impacts of store brands (i.e., private labels) and retail characteristics (scanners, deli, bakery, and pharmacy departments, ATMs, restaurant and store size) on fluid milk prices using 1,740 supermarket-level observations from four cities. Non-parametric results reveal that although private label milk initially exerts a procompetitive effect on milk prices, eventually the effect is to raise the prices of both manufacturers' brands and private labels. Econometric results further reveal that price differentials are larger for reduced-fat milk than for whole milk and that the more enhanced the retail configuration is, the higher milk prices are. Overall, the results attest to some degree of price discrimination by retailers through controlling the brand of milk sold and providing one-stop shopping convenience.

description: Betelgeuse is the nearest Red Supergiant star and it underwent an unusually deep minimum at optical wavelengths during its most recent pulsation cycle. We present submillimetre observations taken by the James Clerk Maxwell Telescope and Atacama Pathfinder Experiment over a time span of 13 years including the optical dimming. We find that Betelgeuse has also dimmed by \sim20\% at these longer wavelengths during this optical minimum. Using radiative-transfer models, we show that this is likely due to changes in the photosphere (luminosity) of the star as opposed to the surrounding dust as was previously suggested in the literature.

description: Generating natural language descriptions for videos, i.e., video captioning, essentially requires step-by-step reasoning along the generation process. For example, to generate the sentence "a man is shooting a basketball", we need to first locate and describe the subject "man", next reason out the man is "shooting", then describe the object "basketball" of shooting. However, existing visual reasoning methods designed for visual question answering are not appropriate to video captioning, for it requires more complex visual reasoning on videos over both space and time, and dynamic module composition along the generation process. In this paper, we propose a novel visual reasoning approach for video captioning, named Reasoning Module Networks (RMN), to equip the existing encoder-decoder framework with the above reasoning capacity. Specifically, our RMN employs 1) three sophisticated spatio-temporal reasoning modules, and 2) a dynamic and discrete module selector trained by a linguistic loss with a Gumbel approximation. Extensive experiments on MSVD and MSR-VTT datasets demonstrate the proposed RMN outperforms the state-of-the-art methods while providing an explicit and explainable generation process.

description: This article examines the influence of campaign contributions on agricultural subsidies. Empirical results revealed that rent seeking works, i.e., campaign contributions of agricultural-related industries influence agricultural subsidies in the manner they best serve contributors' economic interests. Eliminating campaign contributions would significantly decrease agricultural subsidies, hurt farm groups, benefit consumers and taxpayers, and increase social welfare by approximately $5.5 billion. Although contributions are not the only determinants of agricultural subsidies, investment returns to farm PAC contributors are quite high ($1 in contributions brings about $2,000 in policy transfers). In fact, the results are in sharp contrast to the "truthful contributions" assumption of the Grossman-Helpman model.

description: Magnetic behaviour of a mixed spin-1/2 and spin-1 Ising model on the diced lattice is studied by the use of an exact star-triangle mapping transformation. It is found that the uniaxial as well as biaxial single-ion anisotropy acting on the spin-1 sites may potentially cause a reentrant transition with two consecutive critical points. Contrary to this, the effect of next-nearest-neighbour interaction between the spin-1/2 sites possibly leads to a reentrant transition with three critical temperatures in addition to the one with two critical points only. The shape of the total magnetization versus temperature dependence is particularly investigated for the case of ferrimagnetically ordered system.

description: Propagation of an ultrashort pulse of light through strongly scattering media generates an intricate spatio-spectral speckle that can be described by means of the multi-spectral transmission matrix (MSTM). In conjunction with a spatial light modulator, the MSTM enables the manipulation of the pulse leaving the medium; in particular focusing it at any desired spatial position and/or time. Here, we demonstrate how to engineer the point-spread-function of the focused beam both spatially and spectrally, from the measured MSTM. It consists in numerically filtering the spatial content at each wavelength of the matrix prior to focusing. We experimentally report on the versatility of the technique through several examples, in particular as an alternative to simultaneous spatial and temporal focusing, with potential applications in multiphoton microscopy.

description: We have carried out first principles, all-electron computations of the magnetic momentum density $ρ_{mag}({\mathbf p})$ and magnetic Compton profiles (MCPs) for momentum transfer along the [100], [001], and [110] directions in LaSr$_2$Mn$_2$O$_7$ and La$_{1.2}$Sr$_{1.8}$Mn$_2$O$_7$ within the local spin density approximation (LSDA) based band theory framework. Parallel measurements of these three MCPs from a single crystal of La$_{1.2}$Sr$_{1.8}$Mn$_2$O$_7$ at 5 K in a magnetic field of 7 T are also reported. $ρ_{mag}({\mathbf p})$ is shown to contain distinct peaks arising from the occupied majority-spin $t_{2g}$ electrons and to display images of the Fermi surface (FS) in the first and higher Brillouin zones (BZs). The overall shape of the MCPs, $J_{mag}(p_z)$, obtained by integrating $ρ_{mag}({\mathbf p})$ over $p_x$ and $p_y$, is found to be dominated by the majority-spin $t_{2g}$ states. The FS-related fine structure in the MCPs is however substantial only in the [100] MCP, which contains features arising from the large majority-spin hole sheets. The overall shapes and widths of the experimental MCPs along all three directions investigated are in reasonably good accord with theoretical predictions, although some discrepancies indicating inadequacy of the LSDA in treating the magnetic states can be identified. We discuss details of the FS-related signatures in the first and higher BZs in the [100] MCP and show that high resolution magnetic Compton scattering experiments with a momentum resolution of 0.1 a.u. FWHM (full-width-at-half-maximum) or better will be necessary to observe this fine structure. We comment also on the feasibility of using positron annihilation spectroscopy in this connection.

Absent this term, the RH model has only one phase, the normal disordered phase, and suffers from spectral collapse at larger values of the photon-qubit interaction or inter-cavity photon hopping. The photon-photon interaction, no matter how small, stabilizes the system which now exhibits {\it two} quantum phase transitions: Normal phase to {\it photon pair} superfluid (PSF) transition and PSF to single particle superfluid (SPSF). The discrete $Z_4$ symmetry of the Hamiltonian spontaneously breaks in two stages: First it breaks partially as the system enters the PSF and then completely breaks when the system finally enters the SPSF phase. We show detailed numerical results supporting this, and map out the ground state phase diagram.

Transport phenomena in three-dimensional system close to the magnetic quantum critical point: The conserving approximation with the current vertex corrections

description: It is known that various transport coefficients strongly deviate from conventional Fermi-liquid behaviors in many electron systems which are close to antiferromagnetic (AF) quantum critical points (QCP). For example, Hall coefficients and Nernst coefficients in three-dimensional heavy fermion CeCoIn5 and CeCu6-xAux increase strikingly at low temperatures, whose overall behaviors are similar to those in high-Tc cuprates. These temperature dependences are too strong to explain in terms of the relaxation time approximation. To elucidate the origin of these anomalous transport phenomena in three-dimensional systems, we study the current vertex corrections (CVC) based on the fluctuation exchange (FLEX) approximation, and find out decisive role of the CVC. The main finding of the present paper is that the Hall coefficient and the Nernst coefficient strongly increase thanks to the CVC in the vicinity of the AF QCP, irrespective of dimensionality. We also study the relaxation time of quasi-particles, and find that "hot points" and "cold lines" are formed in general three-dimensional systems due to strong AF fluctuations.

description: How does the subjective conceptual framing of conflict impact the warring parties’ attitudes towards political compromise and negotiation? To assess strategies for conflict resolution, researchers frequently try to determine the defining dispute of a given conflict. However, involved parties often view the conflict through fundamentally distinct lenses. Currently, researchers do not possess a clear theoretical or methodological way to conceptualize the complexity of such competing frames and their effects on conflict resolution. This article addresses this gap. Using the Israeli–Palestinian conflict as a case study, we run a series of focus groups and three surveys among Jewish citizens of Israel, Palestinian citizens of Israel (PCIs), and Palestinians in the West Bank. Results reveal that three conflict frames are prominent – material, nationalist, and religious. However, the parties to the conflict differ in their dominant interpretation of the conflict. Jewish Israelis mostly frame the conflict as nationalist, whereas Palestinians, in both the West Bank and Israel, frame it as religious. Moreover, these frames impact conflict attitudes: a religious frame was associated with significantly less willingness to compromise in potential diplomatic negotiations among both Jewish and Palestinian citizens of Israel. Interestingly, differing frames had no significant impact on the political attitudes of West Bank Palestinians, suggesting that the daily realities of conflict there may be creating more static, militant attitudes among that population. These results challenge the efficacy of material solutions to the conflict and demonstrate the micro-foundations underpinning civilians’ conflict attitudes and their implications for successful conflict resolution.
Mapping the Large Scale Structure of the Universe

description: In a large scale view of the universe, galaxies are the basic unit of structure. A typical bright galaxy may contain 100 billion stars and span tens of thousands of light years, but the empty expanses between the galaxies are much larger still. Galaxies are not randomly distributed in space, but instead reside in groups and clusters, which are themselves arranged in an intricate lattice of filaments and walls, threaded by tunnels and pocked with bubbles. Two ambitious new surveys, the Two-Degree Field Galaxy Redshift Survey (2dFGRS) and the Sloan Digital Sky Survey (SDSS), have mapped the three-dimensional distribution of galaxies over an unprecedented range of scales. Astronomers are using these maps to learn about conditions in the early universe, the matter and energy contents of the cosmos, and the physics of galaxy formation.

description: De novo entry by the top 20 U.S. supermarket chains into local markets is examined using Tobit analysis. We find that entry is related to potential entrants' proximity to the local market, market growth, concentration, the number of large chains that are incumbents in the local market, and the competency of potential entrants as measured by their recent internal expansion rate. With regard to competing theories that relate strategic entry barriers to entry patterns, different components of the analysis provide support for different hypotheses. However, the most general model provides little support for the contestability or Chicago efficiency rent hypotheses.
Pervasiveness of self : a critique of P.F. Strawson’s reactive theory of responsibility
Creators: name: Scotland, Andrea Jacqueline
Publisher: name: University of British Columbia
Year: 2009

description: In this thesis, I argue that P.F. Strawson seriously underestimates the controversial nature of the beliefs and attitudes of which the retributive reactive attitudes (RAs) often involve. Although he acknowledges that the RAs involve a "seamy side," he fails to admit they frequently commit the reactive person to psychological, if not metaphysical, beliefs that violate principles of impartiality and rationality. As we shall, this is important in the dialectical context of "Freedom and Resentment", because Strawson's goal of reconciling the compatibilists and incompatibilists about moral responsibility requires the RAs to be free of such controversial presuppositions. I argue that because more modest versions of "seamy" retributive RAs are grounded in false and egoistic beliefs, the incompatibilist will remain skeptical that the gap in consequentialist compatibilism can be filled by the won-metaphysical fact of our "natural proneness" to take up the reactive stance

description: RR Lyrae stars are an important and widely used tracer of the most ancient populations of our Galaxy, mainly due to their standard candle nature. The availability of large scale surveys of variable stars is allowing us to trace the structure of our entire Galaxy, even in previously inaccessible areas like the Galactic disc. In this work we aim to provide an empirical assessment of the completeness of the three largest RR Lyrae catalogues available: Gaia DR2, PanSTARRS-1 and ASAS-SN-II. Using a joint probabilistic analysis of the three surveys we compute 2D and 3D completeness maps in each survey's full magnitude range. At the bright end (G<13) we find ASAS-SN-II and Gaia are near 100% complete in RRab at high latitude (|b|>20deg); ASAS-SN-II has the best completeness at low latitude for RRab and at all latitudes for RRc. At the faint end (G>13), Gaia DR2 is the most complete catalogue for both RR Lyrae types, at any latitude, with median completeness rates of 95% (RRab) and >85% (RRc) outside the ecliptic plane (|β|>25deg). We confirm a high and uniform completeness of PanSTARRS-1 RR Lyrae at 91% (RRab) and 82% (RRc) down to G~18, and provide the first estimate of its completeness at low galactic latitude (|b|<20deg) at an estimated median 65% (RRab) and 50-60% (RRc). Our results are publicly available as 2D and 3D completeness maps, and as functions to evaluate each survey's completeness versus distance or per line-of sight.

description: This article explores the issue of price and expenditure endogeneity in empirical demand analysis. The analysis focuses on the US carbonated soft drink market. We test the null hypothesis that price and expenditures are exogenous in the demand for carbonated soft drinks. Using an Almost Ideal Demand System (AIDS) specification, we strongly reject exogeneity for both prices and expenditures. We find that accounting for price/expenditures endogeneity significantly impacts demand elasticity estimates. We also evaluate the implications of endogeneity issues for testing weak separability.
