description: The empirical velocity of a reaction-diffusion front, propagating into an unstable state, fluctuates because of the shot noises of the reactions and diffusion. Under certain conditions these fluctuations can be described as a diffusion process in the reference frame moving with the average velocity of the front. Here we address pushed fronts, where the front velocity in the deterministic limit is affected by higher-order reactions and is therefore larger than the linear spread velocity. For a subclass of these fronts -- strongly pushed fronts -- the effective diffusion constant $D_f\sim 1/N$ of the front can be calculated, in the leading order, via a perturbation theory in $1/N \ll 1$, where $N\gg 1$ is the typical number of particles in the transition region. This perturbation theory, however, overestimates the contribution of a few fast particles in the leading edge of the front. We suggest a more consistent calculation by introducing a spatial integration cutoff at a distance beyond which the average number of particles is of order 1. This leads to a non-perturbative correction to $D_f$ which even becomes dominant close to the transition point between the strongly and weakly pushed fronts. At the transition point we obtain a logarithmic correction to the $1/N$ scaling of $D_f$. We also uncover another, and quite surprising, effect of the fast particles in the leading edge of the front. Because of these particles, the position fluctuations of the front can be described as a diffusion process only on very long time intervals with a duration $Δt \gg τ_N$, where $τ_N$ scales as $N$. At intermediate times the position fluctuations of the front are anomalously large and non-diffusive. Our extensive Monte-Carlo simulations of a particular reacting lattice gas model support these conclusions.

Aboriginal nursing students’ experiences in two Canadian schools of nursing : a critical ethnography
Creators: name: Martin, Donna Elizabeth
Publisher: name: University of British Columbia
Year: 2010

description: Motivated by a projected shortage of Aboriginal nurses and recurring difficulties in recruitment and retention of Aboriginal peoples in schools of nursing, a critical ethnography was conducted to examine the construction of undergraduate Aboriginal nursing students’ (ANS) experiences in two Canadian schools of nursing. The study was guided by tenets from several theoretical and methodological perspectives: Aboriginal epistemology, decolonizing methodologies for research and Indigenous peoples, cultural safety, and the social organization of knowledge. Data sources included semi-structured interviews with ANS (n=31), Aboriginal nurses (n=5), faculty (n=24), and key informants (n=16) who volunteered to participate. Other data sources were reflexive and descriptive field notes from 200 hours of fieldwork in classroom and laboratory practice sessions. As well, pertinent texts were randomly selected and analyzed. These texts (n=135) included recruitment brochures, nursing textbooks, journal articles, course syllabi, schools’ policies and procedures, and websites to further explicate how nursing discourse shaped ANS’ experiences. Although ANS described long and arduous journeys to and through the schools of nursing, their major concern was inadequate funding from Band sponsorship, Canada Student Loans or other sources. ANS’ stressors were strongly influenced and magnified by the intersectionality of gender, race, culture, economic status, and geographical distance from social supports. ANS’ stories illustrated how they used personal agency to ultimately realize their dream of becoming a highly independent and contributing member of society. Different explanatory models about nursing knowledge, practice and environments created tensions between ANS and teachers and sustained the hegemony within the institution rather than empower the student. Key informants identified how colonization and the history of Aboriginal education and nursing education in Canada continued to shape a disconnection in the student-teacher relationship as experienced by both ANS and nurse educators. Although health care needs of Aboriginal peoples are paramount in Canada, nursing curricula lacked the inclusion of information related to promotion of Aboriginal health. In the rare situation where Aboriginal health was addressed, dismal epidemiological statistics were listed and negative stereotypical portrayals were sustained. Curriculum content about historical influences of colonialism and neo-colonialism shaping Aboriginal health and information about diversity with the Aboriginal culture were absent. Based upon these findings, recommendations were made to enhance the educational experiences of ANS in Canadian schools of nursing.

description: Accurate measurement of the electric current requires a stable and calculable resistor for an ideal current to voltage conversion. However, the temporal resistance drift of a physical resistor is unavoidable, unlike the quantum Hall resistance directly linked to the Planck constant h and the elementary charge e. Lack of an invariant high resistance leads to a challenge in making small current measurements below 1 muA with an uncertainty better than one part in 106. In this work, we demonstrate a current to voltage conversion in the range from a few nano amps to one microamp with an invariant quantized Hall array resistance. The converted voltage is directly compared with the Josephson voltage reference in the framework of Ohm's law. Markedly distinct from the classical conversion, which relies on an artifact resistance reference, this current-to-voltage conversion does not demand timely resistance calibrations. It improves the precision of current measurement down to 8 10 -8 at 1 muA.

description: In our solar system, terrestrial planets and meteoritical matter exhibit various bulk compositions. To understand this variety of compositions, formation mechanisms of meteorites are usually investigated via a thermodynamic approach that neglect the processes of transport throughout the protosolar nebula. Here, we investigate the role played by rocklines (condensation/sublimation lines of refractory materials) in the innermost regions of the protosolar nebula to compute the composition of particles migrating inward the disk as a function of time. To do so, we utilize a one-dimensional accretion disk model with a prescription for dust and vapor transport, sublimation and recondensation of refractory materials (ferrosilite, enstatite, fayalite, forsterite, iron sulfide, metal iron and nickel). We find that the diversity of the bulk composition of cosmic spherules, chondrules and chondrites can be explained by their formation close to rocklines, suggesting that solid matter is concentrated in the vicinity of these sublimation/condensation fronts. Although our model relies a lot on the number of considered species and the availability of thermodynamic data governing state changes, it suggests that rocklines played a major role in the formation of small and large bodies in the innermost regions of the protosolar nebula. Our model gives insights on the mechanisms that might have contributed to the formation of Mercury's large core.

Anatomical Ex-Votos as a Reflection of "Religious Romanization"? Reappraising a Central Italian Practice
Creators: name: Ricci, Luca
Publisher: name: PHASIS
Year: 2020

description: This article seeks to provide a new analysis for the phenomenon of anatomical votive offerings in Central Italy. Traditionally, these items’ distribution was examined in relation to Roman colonization. Simply put, the extension of Rome’s power into Central Italy and the consequent establishment of colonial settlements were thought to be the foundational causes behind the popularity of these votives. This paper debunks such a view, examining the evidence in light of production, distribution and consumption. By doing so, the failures and unsuitability of Romanocentric explanations will become apparent: namely, Rome’s centrality played a limited role at all three aforementioned levels. What the evidence highlights, instead, is a more dynamic interplay among various Central Italian settlements, further emphasizing the importance of localized decision-making. The final result is the formation of a Central Italian koine in which these localized strands took part.

description: Rose Fisher was a very intelligent women, although couldn't read or write. She lived with her parents in Bournemouth where they ran a guest house. Robert Fisher was a boarder and they fell in love and had one child, a son. They moved to London where they set up their own boarding house.

Prior to World War I, the husband went to South America to seek his fortune. During the journey to Argentina, and whilst on the ship, his partner stole all his money;
in Buenos Aires he set up a language school. He later set up a plantation in Brazil.

In 1914, Rose and the son joined him, but she found it very primitive and decided to go home again. The father wanted the son to stay with him, but she refused and as she was penniless the British Consulate paid for their steerage tickets to England. On the ship she came to the attention of the single men, and a family who had a suite took her under their protection and she acted as a servant to them.

The son then went to school in London and gained a scholarship to a grammar school, but when they found out that his father had German parents (although he was born in England himself), the scholarship was withdrawn. After the intervention of the Head Teacher (also the Vicar of the school), another scholarship was obtained.

Rose was considered an 'enemy alien' because of her husband, and she regularly had to attend the local police station to sign in during WWI.

Rose's brother was a soldier during the war and survived. Rose later ran a sweetshop in Hackney.
Function group approach to unconstrained Hamiltonian Yang-Mills theory

description: Starting from the temporal gauge Hamiltonian for classical pure Yang-Mills theory with the gauge group SU(2) a canonical transformation is initiated by parametrising the Gauss law generators with three new canonical variables. The construction of the remaining variables of the new set proceeds through a number of intermediate variables in several steps, which are suggested by the Poisson bracket relations and the gauge transformation properties of these variables. The unconstrained Hamiltonian is obtained from the original one by expressing it in the new variables and then setting the Gauss law generators to zero. This Hamiltonian turns out to be local and it decomposes into a finite Laurent series in powers of the coupling constant.

description: The 1/2-BPS Wilson loop in $\mathcal{N}=4$ supersymmetric Yang-Mills theory is an important and well-studied example of conformal defect. In particular, much work has been done for the correlation functions of operator insertions on the Wilson loop in the fundamental representation. In this paper, we extend such analyses to Wilson loops in the large-rank symmetric and antisymmetric representations, which correspond to probe D3 and D5 branes with $AdS_2 \times S^2$ and $AdS_2 \times S^4$ worldvolume geometries, ending at the $AdS_5$ boundary along a one-dimensional contour. We first compute the correlation functions of protected scalar insertions from supersymmetric localization, and obtain a representation in terms of multiple integrals that are similar to the eigenvalue integrals of the random matrix, but with important differences. Using ideas from the Fermi Gas formalism and the Clustering method, we evaluate their large $N$ limit exactly as a function of the 't Hooft coupling. The results are given by simple integrals of polynomials that resemble the $Q$-functions of the Quantum Spectral Curve, with integration measures depending on the number of insertions. Next, we study the correlation functions of fluctuations on the probe D3 and D5 branes in AdS. We compute a selection of three- and four-point functions from perturbation theory on the D-branes, and show that they agree with the results of localization when restricted to supersymmetric kinematics. We also explain how the difference of the internal geometries of the D3 and D5 branes manifests itself in the localization computation.

description: Recent observations and stellar dynamics simulations suggest that thousand solar mass black holes can form in compact massive young star clusters. Any such clusters in the bulge of their host galaxy will spiral to the center within a few hundred million years, where their intermediate-mass black holes are likely to merge eventually with the galaxy's supermassive black hole. If such mergers are common, then future space-based gravitational wave detectors such as the Laser Interferometer Space Antenna will detect them with such a high signal to noise ratio that towards the end of the inspiral the orbits will be visible in a simple power density spectrum, without the need for matched filtering. We discuss the astrophysics of the inspiral of clusters in the nuclear region of a galaxy and the subsequent merger of intermediate-mass with supermassive black holes. We also examine the prospects for understanding the spacetime geometry of rotating black holes, based on phase connection of the strong signals visible near the end of these extreme mass ratio inspirals.

Management issues in the fisheries commons
Creators: name: McWhinnie, Stephanie F.
Publisher: name: University of British Columbia
Year: 2010

description: This dissertation addresses three issues in managing the fisheries commons: international sharing; international agreements; and property rights management. The overall purpose is to move towards providing consistent and broadly applicable analysis of fisheries management issues by conducting studies at an internationally comparable level. The first issue examined is whether fish stocks that are internationally shared are systematically more exploited than solely owned stocks. With the use of a newly compiled database that includes economic and biological characteristics along with the exploitation status of nearly two hundred fish stocks from around the globe, it is found that sharing is indeed a detrimental force in determining stock status. - The second issue is the natural next question of what effect international agreements have on shared fish stocks. Incorporating information on international cooperative and access agreements into the exploitation status database allows a first-pass analysis of the average effect of cooperative and access agreements on fish stocks. The final issue considered is the impact on productivity of the introduction of property rights management regimes. A parallel analysis of a traditional productivity approach and an index number decomposition to establish the source of productivity changes is conducted on a unique vessel-level dataset of the Norwegian coastal cod fishery and finds that the introduction of individual vessel quotas raised productivity.

Family Ownership, strategy risks and firm's performance

description: A corporate governance framework is required for a successful operation of firms. This framework is generally known to include various aspects of corporate governance, including ownership structure, characteristics of the board of directors and the strategic risks (including both systematic and non-systematic risk) of the firms. And the list of factors included in this corporate governance framework does not stop there. This study is conducted to consider the potential impact of the following two fundamental issues on firm’s performance: (i) family ownership, together with other corporate governance factors; and (ii) strategic risk. Firm’s performance is proxied by each of three dimensions of measurement: (i) the market factor (Tobin’s Q); (ii) the accounting factor (ROA); and (iii) the risk of bankruptcy factor (Z-Score). Data were collected from 289 listed companies in the Ho Chi Minh stock exchange in 2013. This study employs multivariate analysis to identify the effect from family ownership on firm’s performance whereas generalized structural equation model is utilized to investigate the possible link between strategic risk and the performance of listed firms via both direct and indirect channels, Findings from this study indicate that family ownership (the ownership and family involvement in the board of directors; presence of relatives to the founders in the company; and family members being the CEO) could negatively affect firm’s performance which then results in a lower level of firms’ performance (lower ROA) and a higher risk of bankruptcy (higher Z-score). In addition, the relationship between the strategic risks and firm’s performance is presented in both direct and indirect channels. Findings from this study also provide an empirical evidence to confirm the positive effect on firm’s performance from the experienced directors and foreign investors. However, this study fail to support the link between a number of corporate governance factors such as: (i) the board size; the duality (being a chairman and the CEO), the diversity (a presence of female directors in the board structure) and outside directors to firm’s performance. These findings are somewhat consistent with the conclusions from various reports published by the IFC; the State Securities Commission Vietnam (2006, 2010); and International Finance Corporation (2012), in relation to weak applications of the standard corporate governance framework in the Vietnam’s corporate environment. In addition, while there is a significant positive effects of capital expenditure on firm’s performance, the effect is negative for impact of increasing more debt on firm’s performance.

We show that the effective potential of the 1/N expansion is convex for N=4 and N=10 whereas it is not for the "loop" expansion and the case N=1 of the 1/N expansion.

Taking apart the dynamical clock. Fat-tailed dynamical kicks shape the blue-straggler star bimodality

Year: 2020
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: In globular clusters, blue straggler stars are heavier than the average star, so dynamical friction strongly affects them. The radial distribution of BSS, normalized to a reference population, appears bimodal in a fraction of Galactic GCs, with a density peak in the core, a prominent zone of avoidance at intermediate radii, and again higher density in the outskirts. The zone of avoidance appears to be located at larger radii the more relaxed the host cluster, acting as a sort of dynamical clock. We use a new method to compute the evolution of the BSS radial distribution under dynamical friction and diffusion. We evolve our BSS in the mean cluster potential under dynamical friction plus a random fluctuating force, solving the Langevin equation with the Mannella quasi symplectic scheme. This amounts to a new simulation method which is much faster and simpler than direct N-body codes but retains their main feature: diffusion powered by strong, if infrequent, kicks. We compute the radial distribution of initially unsegregated BSS normalized to a reference population as a function of time. We trace the evolution of its minimum, corresponding to the zone of avoidance. We compare the evolution under kicks extracted from a Gaussian distribution to that obtained using a Holtsmark distribution. The latter is a fat tailed distribution which correctly models the effects of close gravitational encounters. We find that the zone of avoidance moves outwards over time, as expected based on observations, only when using the Holtsmark distribution. Thus the correct representation of near encounters is crucial to reproduce the dynamics of the system. We confirm and extend earlier results that showed how the dynamical clock indicator depends both on dynamical friction and effective diffusion powered by dynamical encounters.

The two-eyed seeing garden

description: The Two-eyed Seeing Garden is an ethnobotanical garden that is a living description of the inter-relationships between land, plants and people that explicates two ways of seeing. The goal of the Two-eyed Seeing Garden is to combine two frameworks, one of Indigenous Traditional Knowledge and one of Western Scientific Knowledge, in an attempt to create a bridge between the two knowledges in order for the inter-relationships between the two systems to be made visible. The Two-eyed Seeing Garden emphasizes the worldview of Indigenous Ecological Knowledge as an independent valid knowledge system that describes local knowledge in connection with other local knowledges, nearby and far away. These knowings can be thought of as layers that begin to intersect and eventually connect the same way as ripples do in a pond. Small and central, yet moving out. The physical garden is this too. It is a small place that is nested within a larger region. Although it may have walls and is distinct from it’s immediate surroundings, it can connect to the larger region. The Two-eyed Seeing Garden is an example of wholeness and connectivity from its most minute aspects to its situatedness in the larger context. The relationships make the invisible visible and describe the co-creation and co-existence of all those that inhabit this land now and since time immemorial.

description: We report on realization of 10 quantum Hall devices in series fabricated using epitaxial graphene on silicon carbide. Precision measurements with a resistance bridge indicates that the quantized Hall resistance across an array at filling factor 2 is equivalent to 5 h/e^2 within the measurement uncertainty of approximately 4 10-8. A quantum-Hall phase diagram for the array shows that a metrological quantization of 5 h/e^2 can be achieved at the magnetic field of 6 T and temperature of 4 K. This experiment demonstrates the possibility of timely unchangeable resistance reference in various ranges in relaxed experimental conditions.

description: Nuclear forces can be systematically derived using effective chiral Lagrangians consistent with the symmetries of QCD. I review the status of the calculations for two- and three-nucleon forces and their applications in few-nucleon systems. I also address issues like the quark mass dependence of the nuclear forces and resonance saturation for four-nucleon operators.

description: Wigner molecules formed at high magnetic fields in circular and elliptic quantum dots are studied by exact diagonalization (ED) and unrestricted Hartree-Fock (UHF) methods with multicenter basis of displaced lowest Landau level wave functions. The broken symmetry states with semi-classical charge density constructed from superpositions of the ED solutions are compared to the UHF results. UHF overlooks the dependence of the few-electron wave function on the actual relative positions of electrons localized in different charge puddles and partially compensates for this neglect by an exaggerated separation of charge islands which are more strongly localized than in the exact broken-symmetry states.

description: The drug discovery stage is a vital aspect of the drug development process and forms part of the initial stages of the development pipeline. In recent times, machine learning-based methods are actively being used to model drug-target interactions for rational drug discovery due to the successful application of these methods in other domains. In machine learning approaches, the numerical representation of molecules is critical to the performance of the model. While significant progress has been made in molecular representation engineering, this has resulted in several descriptors for both targets and compounds. Also, the interpretability of model predictions is a vital feature that could have several pharmacological applications. In this study, we propose a self-attention-based multi-view representation learning approach for modeling drug-target interactions. We evaluated our approach using three benchmark kinase datasets and compared the proposed method to some baseline models. Our experimental results demonstrate the ability of our method to achieve competitive prediction performance and offer biologically plausible drug-target interaction interpretations.
Pygmalionismus. Über Narzissmus, Gender und Kunst
Creators: name: Emmrich, Thomas
Publisher: name: PHASIS
Year: 2020

description: On the basis of Ovid’s story of Pygmalion in the tenth book of the Metamorphoses, the contribution at hand aims to demonstrate that the production of art cannot be traced back to a pure, ideal or august source: to a divine inspiration, for example, as postulated since Homer’s Iliad by the motif of the invocations of the muses; or to the autonomous creative subject of the modern aesthetics of the genius and aestheticism. Ovid, with his figure of the paradigmatic and tradition forming artist, illustrates that, on the contrary, art is based on something inferior and abject, namely on a narcissist misalliance of the artist towards his work, which, in the case of Pygmalion, grows into an incestuous structure of desire. Since Pygmalion’s narcissism is related to a, or rather his, simulacrum of the ideal woman, it is furthermore important to reconstruct the distortions pertaining to gender policies that can be connected to the creation of art.

The Shaping of the Red Rectangle Proto-Planetary Nebula

description: I argue that the slowly expanding biconical structure of the Red Rectangle--a nebula around the post asymptotic giant branch binary stellar system HD 44179--can be formed by intermittent jets blown by the accreting companion. The bright biconical structure of the Red Rectangle nebula can be understood to be composed of a multiple double-ring system. In the proposed shaping process, one among several processes through which a companion can shape the circumbinary gas, the companion accretes mass from the slow wind blown by the evolved mass losing star. An accretion disk is formed, and if mass accretion is larger than a critical value, two jets, or a collimated fast wind (CFW) are blown. If the high mass loss rate duration is long, bipolar lobes are formed. If, on the other hand, mass loss rate is intermittent, and during one orbital period the slow wind fills a region which does not extend much beyond the binary system, then only a fraction of the double-lobe structure is formed, namely, rings. This, I propose, was the case with the progenitor of the Red Rectangle, where intermittent episodes of enhanced mass loss rate led to the formation of a multiple double-ring system.

description: Developing performance measurement is a necessary element for the effective management of organizations. Performance measurement has been gaining in importance in both operations and management literature. In this paper an evaluation of the development and implementation of performance measures is presented. Investigation of the process from an organizational viewpoint provides insights into the advantages and disadvantages of a strategic activity-based development framework for performance measurement. General issues and implications for the management of performance measurement development and implementation provide some fundamental guidelines.
On irregular prime power divisors of the Bernoulli numbers

description: Let $B_n$ ($n = 0, 1, 2, ...$) denote the usual $n$-th Bernoulli number. Let $l$ be a positive even integer where $l=12$ or $l \geq 16$. It is well known that the numerator of the reduced quotient $|B_l/l|$ is a product of powers of irregular primes. Let $(p,l)$ be an irregular pair with $B_l/l \not\equiv B_{l+p-1}/(l+p-1) \modp{p^2}$. We show that for every $r \geq 1$ the congruence $B_{m_r}/m_r \equiv 0 \modp{p^r}$ has a unique solution $m_r$ where $m_r \equiv l \modp{p-1}$ and $l \leq m_r < (p-1)p^{r-1}$. The sequence $(m_r)_{r \geq 1}$ defines a $p$-adic integer $χ_{(p, l)}$ which is a zero of a certain $p$-adic zeta function $ζ_{p, l}$ originally defined by T. Kubota and H. W. Leopoldt. We show some properties of these functions and give some applications. Subsequently we give several computations of the (truncated) $p$-adic expansion of $χ_{(p, l)}$ for irregular pairs $(p,l)$ with $p$ below 1000.

description: Rota-Baxter operators present a natural generalisation of integration by parts formula for the integral operator. In 2015, Zheng, Guo, and Rosenkranz conjectured that every injective Rota-Baxter operator of weight zero on the polynomial algebra $\mathbb{R}[x]$ is a composition of the multiplication by a nonzero polynomial and a formal integration at some point. We confirm this conjecture over any field of characteristic zero. Moreover, we establish a structure of an ind-variety on the moduli space of these operators and describe an additive structure of generic modality two on it. Finally, we provide an infinitely transitive action on codimension one subsets.

description: The correlations, entanglement entropy, and fidelity susceptibility are calculated for a one-dimensional spin-1/2 XXZ chain with anisotropic power-law long range interactions by employing the density matrix renormalization group method. In particular, this long-range interaction is assigned to ferromagnetic for transversal components, while it can be either ferro- or antiferromagnetic for the longitudinal spin component. Two ground-state phase diagrams are established versus the anisotropy of the interactions which not only changes the phase boundaries of the counterparts with short-range interactions, but also leads to the emergence of exotic phases. We found that the long-range interactions of the z-component results in a Wigner crystal phase, whereas the transversal one may break a continuous symmetry, resulting in a continuous symmetry breaking phase.

description: We investigate the electronic instabilities in carbon nanotubes of short radius, looking for the breakdown of the Luttinger liquid regime from the singular behavior of the charge stiffnesses at low energies. We show that such a breakdown is realized in the undoped (3,3) nanotubes through the onset of phase separation into regions with opposite electronic current. The phenomenology derived from this regime is consistent with the formation of a pseudogap in the single-particle spectrum as well as with a divergent diamagnetic susceptibility, as observed in the experiments carried out in carbon nanotubes of small diameter.
