description: We have synthesized MoS$_{2}$ incorporated $α$-Fe$_{2}$O$_{3}$/ZnO nanocomposites by the hydrothermal process. The effect of incorporating ultrasonically exfoliated MoS$_{2}$ on the photocatalytic performance of $α$-Fe$_{2}$O$_{3}$/ZnO nanocomposites has been demonstrated. Structural, morphological and optical characteristics of the nanomaterials are investigated by performing Rietveld refinement of powder X-ray diffraction patterns, field emission scanning electron microscopy and UV-visible spectroscopy. The photoluminescence spectra of the nanocomposites show that the recombination of photogenerated electron-hole pairs is suppressed due to incorporating MoS$_{2}$ nanosheets. The ultrasonicated MoS$_{2}$ incorporated $α$-Fe$_{2}$O$_{3}$/ZnO nanocomposite shows 91% and 83% efficiency to degrade RhB dye and antibiotic ciprofloxacin under solar illumination. Active species trapping experiments reveal that the hydroxyl radicals play a significant role in RhB degradation. Likewise, the dye degradation efficiency, the amount of hydrogen produced by this nanocomposite via photocatalytic water splitting is also higher as compared to non-ultrasonicated MoS$_{2}$ incorporated $α$-Fe$_{2}$O$_{3}$/ZnO and $α$-Fe$_{2}$O$_{3}$/ZnO nanocomposites as well as Degussa P25 titania nanoparticles. This indicates the promising potential of the incorporation of ultrasonicated MoS$_{2}$ with $α$-Fe$_{2}$O$_{3}$/ZnO nanocomposite for generation of carbon-free hydrogen by water splitting. The substantial increase in the photocatalytic efficiency of $α$-Fe$_{2}$O$_{3}$/ZnO after incorporation of ultrasonicated MoS$_{2}$ can be attributed to its favorable band structure, large surface to volume ratio, effective segregation and migration of photogenerated electron-hole pairs at the interface of heterojunction and the active edge sites provided by few-layer MoS$_{2}$ nanosheets.
title: Demystification of Graph and Information Entropy
Creators: name: Frederickson, Bryce
Publisher: name: Utah State University
Year: 2020

description: Shannon entropy is an information-theoretic measure of unpredictability in probabilistic models. Recently, it has been used to form a tool, called the von Neumann entropy, to study quantum mechanics and network flows by appealing to algebraic properties of graph matrices. But still, little is known about what the von Neumann entropy says about the combinatorial structure of the graphs themselves. This paper gives a new formulation of the von Neumann entropy that describes it as a rate at which random movement settles down in a graph. At the same time, this new perspective gives rise to a generalization of von Neumann entropy to directed graphs, thus opening a new branch of research. Finally, it is conjectured that a directed cycle maximizes von Neumann entropy for directed graphs on a fixed number of vertices.

The solutions cannot be written explicitly in a closed form, so their properties are investigated numerically. The five-dimensional metric is regular everywhere except on the location of original bolt in four-dimensional Atiyah-Hitchin base space. On each time-fixed slices, the metric, asymptotically approaches an Euclidean Taub-NUT space.

description: A perfect number is a positive integer N that equals the sum of its properdivisors. While even perfect numbers have been classified, the existence of an oddperfect number remains an open question in number theory. In this paper, wepresent a contradiction that arises in the divisor structure of any hypothetical oddperfect number. Specifically, we demonstrate that the largest proper divisor mustbe N/2, which cannot be an integer for an odd N. This contradiction invalidatesthe necessary conditions for a perfect number, thereby proving that no odd perfect number can exist.
title: Simplicity as a New Environmental Virtue
Creators: name: Wheeler, Justin
Publisher: name: Utah State University
Year: 2020

description: This paper argues for the addition of a new environmentally focused virtue, simplicity, to the virtue ethical framework developed by Aristotle. First, relevant background from Aristotle’s virtue ethics are developed including the crucial, “doctrine of the mean”, a balance between excess and deficiency of a specified character trait. The tenets of the new virtue simplicity are developed with practical examples based on Aristotle’s method of developing a virtue of character. Simplicity is proposed as a desire to take the appropriate amount from the natural world and an acceptance of one’s circumstances. Those possessing simplicity will not fall victim to the pervasive “keeping up with the Joneses” mentality. Examples are given of historical figures the author believes to have possessed simplicity. People like Philip Cafaro, Henry David Thoreau, and even Warren Buffett are discussed as potential “mentors” for our own journeys into simplicity. Finally, an expansion on the intertwined nature of simplicity with the cardinal virtues of justice, wisdom, piety, temperance, and courage is given satisfying Aristotle’s “unity of the virtues” requirement.

description: In 1952, Heinrich Scholz published a question in the Journal of Symbolic Logic asking for a characterization of spectra, i.e., sets of natural numbers that are the cardinalities of finite models of first order sentences. Günter Asser asked whether the complement of a spectrum is always a spectrum. These innocent questions turned out to be seminal for the development of finite model theory and descriptive complexity. In this paper we survey developments over the last 50-odd years pertaining to the spectrum problem. Our presentation follows conceptual developments rather than the chronological order. Originally a number theoretic problem, it has been approached in terms of recursion theory, resource bounded complexity theory, classification by complexity of the defining sentences, and finally in terms of structural graph theory. Although Scholz' question was answered in various ways, Asser's question remains open. One appendix paraphrases the contents of several early and not easily accesible papers by G. Asser, A. Mostowski, J. Bennett and S. Mo. Another appendix contains a compendium of questions and conjectures which remain open.

Year: 2021

description: This paper aims to present and highlight the importance of factors resulting from Repertory Grid Analysis (R.G.A.). Strategic planning management issues concerning the management of museum audience are studied. A short description of the R.G.A. and the corresponding literature is cited, and an empirical application of the aforementioned method in a sample of 128 university students, takes place. The application of RGA produced 1345 interpretation models (constructs) which were coded and analyzed with three multivariable statistical techniques. The paper clearly demonstrates the importance of the analysis of constructs in relation to the management (local authorities or private institutions) suggestions that concern the museums of a specific area. Also, it contributes to the evolution of a new research area for the Destination Marketing Management with emphasis on Place design practices and development. Cultural offers and special managerial suggestions about particular groups of museums (strategic museum groups), are also discussed.

description: We present sensitive 7 mm observations of the H53$α$ recombination line and adjacent continuum, made toward the Orion BN/KL region. In the continuum we detect the BN object, the radio source I (GMR I) and the radio counterpart of the infrared source n (Orion-n). Comparing with observations made at similar angular resolutions but lower frequency, we discuss the spectral indices and angular sizes of these sources. In the H53$α$ line we only detect the BN object. This is the first time that radio recombination lines are detected from this source. The LSR radial velocity of BN from the H53$α$ line, $v_{LSR} = 20.1 \pm 2.1$ km s$^{-1}$, is consistent with that found from previous studies in near-infared lines. While the continuum emission is expected to have considerable optical depth at 7 mm, the observed H53$α$ line emission is consistent with an optically-thin nature and we discuss possible explanations for this apparent discrepancy. There is evidence of a velocity gradient, with the NE part of BN being redshifted by $\sim 10$ km s$^{-1}$ with respect to the SW part. This is consistent with the suggestion of Jiang et al. that BN may be driving an ionized outflow along that direction.

description: Daniel Sykes, an Anthropology student at Utah State University used his Honors Capstone opportunity to understand the evolution of reproduction over the course of two semesters. During Fall of 2019, he focused on overviewing what Biological Archaeologists, Biologists, and Chemists understand of the evolution of various forms of reproduction from the distant past. During the Spring, he focused on the cutting edge allopathic research in fertility treatments and some of the social implications. Sykes posits that human society has the opportunity to treat infertility in the queer (lgbtqia+) community, given these up-and-coming treatments, even those forms of infertility that arise from queernesss, per se. Queertility is a valid form of fertility that can be expanded as research continues.

While a phase-locked dark-dark vector soliton was only observed in fiber lasers of positive dispersion, a phase-locked dark-bright vector soliton was obtained in fiber lasers of either positive or negative dispersion. Numerical simulations confirmed the experimental observations, and further showed that the observed vector solitons are the two types of phase-locked polarization domain-wall solitons theoretically predicted.

Cyclic nucleotide phosphodiesterases of the superior cervical ganglion
Creators: name: Boudreau, Robert James
Publisher: name: University of British Columbia
Year: 2010

description: A modification of the assay of cyclic nucleotide phosphodiesterase involving batch use of Dowex 1 anion exchange resin was developed. This assay produced quantitative recoveries of adenosine, guanosine, and their metabolites from the resin slurry. The assay was suitable for use in crude preparations containing purine catabolizing enzymes. Cyclic nucleotide phosphodiesterase was examined in canine and bovine superior cervical ganglia. Activity in crude supernatant fractions was only slightly stimulated by Ca⁺⁺ despite the presence of protein activating factor. Three forms of phosphodiesterase were resolved from bovine ganglia supernatant extracts by chromatography on DEAE-cellulose. The first enzyme eluted (D[sub I]) was completely specific for cyclic GMP, while the other two (D[sub II]and D[sub III]) hydrolyzed both cyclic AMP and cyclic GMP ; all were free of heat stable protein activator. Each enzyme was inhibited by low concentrations of Ca⁺⁺ in the assay medium. Inhibition by Ca⁺⁺ was reversed by the addition of protein activator but activity did not increase above the control level. Cyclic AMP hydrolysis by D[sub II] was stimulated by micromolar concentrations of cyclic GMP. This stimulation was reduced by Ca⁺⁺ unless protein activator was present. The kinetics of cyclic nucleotide hydrolysis by each of the three enzymes were examined. All enzyme species displayed nonlinear double reciprocal plots of substrate hydrolysis. Through the use of reversible inhibition kinetics and nonlinear least squares fitting, rate equations to describe the data were evaluated. Apparent negatively cooperative behaviour was observed for the hydrolysis of cyclic GMP by the first peak eluted (K₁ < K₂ and V₁ < V₂). The two cyclic AMP-cyclic GMP hydrolyzing enzymes displayed apparent positive cooperativity for cyclic GMP hydrolysis (K₁ > K₂ and V₁ > V₂), and negative. cooperativity for cyclic AMP hydrolysis (K₁ < K₂ and V₁ < V₂). The kinetic behaviour displayed by all three enzyme species could be explained using variations of a model consisting of an enzyme with two initially equivalent interacting sites.
title: The Impact of University and Atelier Instruction on Classical Realism Art in America
Creators: name: Brock, Rebecca Chyenne
Publisher: name: Utah State University
Year: 2020

description: Students who aspire to become realism artists are faced with a difficult decision about where to learn classical drawing and painting skills. Where should they study and what type of education should they pursue? These students can attend a college or university and obtain a traditional contemporary art education. This choice will provide young artist with a basic education in painting and drawing. Students will also receive an education across different areas of art as well as a liberal arts education. However, students may select to attend an atelier, fashioned after the 19th century pattern for training classical artists. This decision will provide a highly focused classical drawing and painting educational path, but little else. This research will examine documents, articles, and professional journals related to art education. Additionally, interviews were conducted with instructors and administrators from 16 of the best college and universities in the United States that teach painting and drawing. Interviews were also conducted with instructors and administrators from 16 of the best ateliers across the United States. From the literature, personal interviews, and surveys the research has uncovered a series of pros and cons associated with each path. In evaluating the pros and cons the research finding is that for students who wish to pursue a classical realism art career it may not be the best decision to simply default to one option. Rather, the research points towards a conclusion that a prospective classical artist should pursue a carefully crafted individual academic roadmap. This roadmap may include a college and university degree program, however incorporating atelier training is equally important. Conversely, a student may choose a full-time atelier program and augment their education with college and university studies. Each prospective artist must weigh the benefits and opposing factors of each educational option to decide for them self how best to balance the best of each in order to achieve their goal of becoming a classical realism artist.

description: We investigated the ferroelectric domain wall propagation in epitaxial Pb(Zr,Ti)O3 thin films over a wide temperature range (3 - 300 K). We measured the domain wall velocity under various electric fields and found that the velocity data is strongly nonlinear with electric fields, especially at low temperature. We found that, as one of surface growth problems, our domain wall velocity data from ferroelectric epitaxial film could be classified into the creep, depinning, and flow regimes due to competition between disorder and elasticity. The measured values of velocity and dynamical exponents indicate that the ferroelectric domain walls in the epitaxial films are fractal and pinned by a disorder-induced local field.

description: Excerpts from the report: Material presented in this publication represents, for the most part, completely new series relating to charges for marketing farm food products. They show retail cost per unit of farm food products, farm value of equivalent produce, the price spread or marketing margin, an estimate of marketing charges, and the farmer's share of the retail cost. Some of the material has been revised only slightly, but the bulk of the data represents substantial revision or series not heretofore available. Every effort was made to derive series of farm-retail price spreads and marketing charges for food products that would be thoroughly representative of that part of sales by farmers of food products which finds its way into domestic consumption by the civilian population. This coverage is intended to include all farm food products that are both sold by farmers and purchased by consumers—that is, all farm products which move through the marketing system into domestic human consumption. Important categories of total food consumption excluded by this definition are foods consumed in households of producers and foods of non-farm origin. The latter class includes quantities of foods which are farm products but which do not originate on farms of producers in the continental United States

description: The Balearics’ economy is heavily dependent on tourism, generating revenue and employment; nevertheless, nowadays the archipelago is considered a traditional destination that could be currently reaching its mature stage. In this context, the new marketing guidelines for tourism adopted by the Balearic Government in recent years are based on promoting the development of different tourism products. The aim of this new strategy is to promote high value added products, such as the yachting charter tourism, to explore new market segments and to improve the image of the destination according to the consumer behaviour.This paper identifies the strengths, weaknesses, opportunities and threats (SWOT) of the yacht charter sector, using empirical evidence on the demand and supply side. The results will be very useful for this sector to design and launch successfully new marketing and promotion strategies and policies in order to maintain tourism activity, increase tourist average expenditure, lengthen the tourist season and change the image of the islands.

description: This work reports a novel time-domain expression for the current-response kernels of a Josephson tunnel junction between BCS superconductors with in general different energy gaps, and its use to simulate the classical dynamics of such junctions. The simulations show a dynamic regime characterized by the resonance between the Josephson oscillations and the gap oscillations in the asymptotics of the current kernels that has not been studied previously. The resonance manifests itself as a hysteresis in the dc current-voltage characteristics of the current-biased junctions in the voltage range above the energy gap, in addition to the usual ``inertial'' hysteresis characteristic for tunnel junctions at voltages below the energy gap. Features of the IV curves related to the gap resonance, including the above-the-gap hysteresis, should manifest themselves in many structures and devices utilizing high-quality Josephson tunnel junctions with relatively large, but achievable current densities.

description: The parameterised post-Newtonian (PPN) formalism is a weak-field slow-motion approximation for both GR and some of its generalisations. It permits various parameterisations of the motion, among which are the Lagrange-type and Gauss-type orbital equations. Often, these equations are developed under the Lagrange constraint, which makes the evolving orbital elements parameterise instantaneous conics tangent to the orbit. Arbitrary mathematically, this choice of a constraint is convenient under perturbations dependent only on positions. Under perturbations dependent also on velocities (like relativistic corrections) the Lagrange constraint unnecessarily complicates solutions that can be simplified by introducing a freedom in the orbit parameterisation, which is analogous to the gauge freedom in electrodynamics and gauge theories. Geometrically, this freedom is the freedom of nonosculation, i.e. of the degree to which the instantaneous conics are permitted to be non-tangent to the actual orbit. Under the same perturbation, all solutions with different degree of nonosculation look mathematically different, though describe the same physical orbit. While non-intuitive, the modeling of an orbit with a sequence of nontangent instantaneous conics can at times simplify calculations. The appropriately generalised ("gauge-generalised") Lagrange-type equations, and their applications, appeared in the literature hitherto. We in this paper derive the gauge-generalised Gauss-type equations and apply them to the PPN two-body problem. Fixing the gauge freedom in three different ways (i.e. modeling an orbit with non-osculating elements of three different types) we find three parameterisations of the PPN two-body dynamics. These parameterisations render orbits with either a fixed non-osculating semimajor axis, or a fixed non-osculating eccentricity, or a fixed non-osculating argument of periastron.

description: As part of a program to measure abundance ratios in stars beyond 15 kpc from the Galactic center, we have discovered a metal-poor star in the outer halo with a unique chemical signature. We originally identified it in the Sloan Extension for Galactic Understanding and Exploration (SEGUE) survey as a distant metal-poor star. We obtained a follow-up spectrum using the Echellette Spectrograph and Imager (ESI) at the Keck 2 telescope, and measure [Fe/H] =-3.17, [Mg/Fe] =-0.10 and [Ca/Fe] =+1.11. This is one of the largest over-abundances of Ca measured in any star to date; the extremely low value of [Mg/Ca]=-1.21 is entirely unique. To have found such an unusual star in our small sample of 27 targets suggests that there may be previously unobserved classes of stars yet to be found in situ in the Galactic halo.

description: The objective of this project was to treat petroleum refinery wastewater using a combination of anaerobic and aerobic processes, namely an Up-flow Anaerobic Sludge Blanket (UASB) reactor paired with a Rotation Algae Biofilm Reactor (RABR), respectively, to produce a treated effluent. The treatment method developed needed to produce a cost-effective and efficient way to decrease nitrogen, phosphorous, total suspended solids (TSS), and COD concentrations to below State of Utah limitations. It was demonstrated that RABR treatment was capable of reducing effluent concentrations of nitrogen, phosphorus, and TSS to State of Utah limitations. RABR treatment did not significantly reduce COD from the wastewater. The COD reduction requirement, however, was met through anaerobic digestion of the wastewater. Therefore, our system proved effectual at the treatment of the wastewater and met all design criteria.

description: Recently, it has been proposed that the Navier-Stokes equations and a relevant linear advection model have the same long-time statistical properties, in particular, they have the same scaling exponents of their structure functions. This assertion has been investigate rigorously in the context of certain nonlinear deterministic phenomenological shell model, the Sabra shell model, of turbulence and its corresponding linear advection counterpart model. This relationship has been established through a "homotopy-like" coefficient $λ$ which bridges continuously between the two systems. That is, for $λ=1$ one obtains the full nonlinear model, and the corresponding linear advection model is achieved for $λ=0$. In this paper, we investigate the validity of this assertion for certain stochastic phenomenological shell models of turbulence driven by an additive noise. We prove the continuous dependence of the solutions with respect to the parameter $λ$. Moreover, we show the existence of a finite-dimensional random attractor for each value of $λ$ and establish the upper semicontinuity property of this random attractors, with respect to the parameter $λ$. This property is proved by a pathwise argument. Our study aims toward the development of basic results and techniques that may contribute to the understanding of the relation between the long-time statistical properties of the nonlinear and linear models.
How Trauma Mirrors a Corrupted Codebase:  A Neuromorphic Computing View on PTSD, Jezreel Dequina
Creators: name: Dequina, Jezreel
Publisher: name: Zenodo
Year: 2025

description: This paper explores Post-Traumatic Stress Disorder (PTSD) through the metaphorical and interdisciplinary lens of systems engineering and computational logic. It proposes that trauma is not merely psychological pain but a form of internal data corruption that disrupts memory, logic, and emotional processing. By applying concepts such as feedback loops, stimuli as code and debugging, the paper reframes trauma recovery as a structural process of system restoration. This model offers an alternative framework for understanding PTSD and presents further opportunities for recovery pathways. This paper will be offering a unique synthesis between neuromorphic computing, mental health and machine applications.Jezreel Dequina
title: Increasing Vaccine Accessibility through Cost Alternative Manufacturing and Elimination of the Cold Chain
Creators: name: Madsen, Jorgen
Publisher: name: Utah State University
Year: 2015

description: Millions of people die each year from infectious diseases. This is partly due to the difficulty of transporting temperature dependent vaccines through what is called the cold chain in developing countries. I hypothesize that we can increase vaccine accessibility by finding cost effective alternatives to vaccine production and by eliminating the cold chain through vaccine stabilizers. The gold standard in purification of influenza virus is by means of ultracentrifugation. Although effective, this process is very expensive and thus impractical for developing countries. I hypothesize that column chromatography can be a cost efficient alternative that is as effective as ultracentrifugation. The purification ability of column chromatography was tested by comparing two different chromatography resins. The Capto Q resin separates proteins on the basis of protein charge. The Capto 700 resin separates proteins on the basis of both size and charge. It was found that while protein separation occurred, more research will be required to assure full viral protein purification.
It is hypothesized that vaccine stabilizers can be used to eliminate the cold chain. The effect of the gelatin on inactivated influenza virus vaccines was evaluated using hemagglutinin (HA) assays and neuraminidase (NA) assays. The assays evaluate viral protein activity in samples exposed to elevated temperatures for set periods of time (1 min, 5 min, 10 min, 20 min, 40 min, 60 min, 120 min, 240 min, 300 min, and 360 min). Elevated temperatures (45, 52, and 60 degrees Celsius) facilitated an accelerated stability test, which simulates extended effects of time on vaccines. In addition to testing different temperatures, the following concentrations of collagen were used as percent by total volume: 0.3%, 1%, 3%, and 10%. These were tested for optimizing the stabilization of the vaccine. The results of the neuraminidase assay show that 3% collagen significantly increased the stability of the vaccine by approximately 10,000 fold.

description: Simulation schemes that allow to change molecular representation in a subvolume of the simulation box while preserving the equilibrium with the surrounding introduce conceptual problems of thermodynamic consistency. In this work we present a general scheme based on thermodynamic arguments which ensures thermodynamic equilibrium among the molecules of different representation. The robustness of the algorithm is tested for two examples, namely an adaptive resolution simulation, atomistic/coarse-grained, for a liquid of tetrahedral molecules and an adaptive resolution simulation of a binary mixture of tetrahedral molecules and spherical solutes.

L’innovazione tecnologica nella scuola: come perseguire un’innovazione tecnologica sostenibile ed efficace
Creators: name: Calvani, Antonio
Publisher: name: Firenze University Press
Year: 2014
Subjects: effectiveness; evidence based education; sustainability; technological innovation

description: Starting out from the document drawn up by OECD on the Italian “Digital School” project for the introduction of technological innovation in schools, the author discusses the criteria to which innovation policies based on the principles of sustainability and maximum pedagogical impact should be subject, in an Evidence Based Education perspective. Historically we tend to overestimate the positive effects of technology on learning, while research has already highlighted their limitations, which are restricted to specific areas, at the same time pointing to the risks related to consequent cognitive overload. Suggestions for decision makers are made, underlining the need to recover the educational relationship with easy technologies, take into account the cognitive balance between reading paper and digital reading and finalize well the use of technology for achieving specific objectives.

description: This paper presents a first attempt at performing a precise and automatic identification of the linking behaviour in a scientific domain through the analysis of the communication of the related academic institutions on the web. The proposed approach is based on the paradigm of multiple viewpoint data analysis (MVDA) than can be fruitfully exploited to highlight relationships between data, like websites, carrying several kinds of description. It uses the MultiSOM clustering and mapping method. The domain that has been chosen for this study is the domain of Computer Science in Germany. The analysis is conduced on a set of 438 websites of this domain using all together, thematic, geographic and linking information. It highlights interesting results concerning both global and local linking behaviour.
Study of nucleon resonances at EBAC@JLab

description: We present the dynamical origin of the P11 nucleon resonances resulting from a dynamical coupled-channels (DCC) analysis of meson production reactions off a nucleon target, which is conducted at Excited Baryon Analysis Center (EBAC) of Jefferson Lab. Two resonance poles are found in the energy region where the Roper resonance P11(1440) was identified. Furthermore, the two resonance poles and the next higher resonance pole corresponding to P11(1710) are found to originate from a single bare state.

description: Instrument models (IMs) enable the reduction of systematic error in transit spectroscopy light curve data, but, since the model formulation can influence the estimation of science model parameters, characterization of the instrument model effects is crucial to the interpretation of the reduced data. We analyze a simple instrument model and assess its validity and performance across Hubble WFC3 and STIS instruments. Over a large, n=63, sample of observed targets, an MCMC sampler computes the parent distribution of each instrument model parameter. Possible parent distribution functions are then fit and tested against the empirical IM distribution. Correlation and other analyses are then performed to find IM relationships. The model is shown to perform well across the 2 instruments and 3 filters analyzed and, further, the Student's t-distribution is shown to closely fit the empirical parent distribution of IM parameters and the Gaussian is shown to poorly model the observed distribution. This parent distribution can be used in the MCMC prior fitting and demonstrates IM consistency for wide scale atmospheric analysis using this model. Finally, we propose a simple metric based on light curve residuals to determine model performance, and we demonstrate its ability to determine whether a derived spectrum under this IM is high quality and robust.

Lingua, memoria e identità nei racconti dei migranti ispanoamericani
Creators: name: Calvi, Maria Vittoria
Publisher: name: Università degli  Studi di Milano
Year: 2014
Subjects: lingua e identità; narrazione orale e identità; spagnolo e italiano; migrazioni ispanoamericane

description: In a wide-ranging theoretical framework, principally based upon discourse analysis and the studies on language and identity, this article explores the construction of identity in a corpus of oral narratives collected among the Spanish speaking communities in Milan, by means of sociolinguistic and biographic interviews, seen as a complex event in which both parties act as active participant-observers. The study focuses on the features of these life stories, taking into account the ways in which the immigrants compare the two worlds an collocates themselves between the two cultures, the function of code-switching, the linguistic expression of ‘agency’ (Giddens 1979) and the use of deictics.

description: Excerpts from the report: This statistical supplement is the first that has been issued since the release of the original report under the same title, and called Miscellaneous Publication No. 576. That was in September 1945. It carried the various monthly series on price spreads for farm food products through August 1944, and supplanted earlier series compiled for 58 foods. This supplement begins with January 1944 and carries the series through March 1947. Many revisions were made for the first 7 months of 1944 in the estimates of farm value, marketing margin, and the farmer's share of the retail price for various food products. These revisions are given in this supplement and supplant the unrevised data shown in the original publication, Miscellaneous Publication No. 576. Full details describing basic data, methods, and procedures are given in the original publication. These include a description of the quantities of the farm products included in the "market basket."
EARNINGS TARGETS IN SPANISH HOTEL INDUSTRY: AN APPROXIMATION
Creators: name: Parte Esteban, Laura

Publisher: name: tourismos
Year: 2011

description: In this paper, two earnings targets - avoiding losses and earnings decreases - are analyzed in Spanish hotel industry. The methodology used as a proxy to earnings targets is frequency histograms. Particularly, the existence of a “kink” in the distribution of reported earnings around zero is examined. The access to financial resources to start or to consolidate expansion policies is an important issue to the companies belonging to our sample. This specific scenario allows us to study how to reach earnings benchmarks under debt covenant hypothesis. Likewise, Spanish tourism sector is characterised by small firms and most of them are governed by families. We explore the relationship between earnings benchmarks and this particular ownership structure. Finally, we examine the presence of auditors (and Big4 auditors) as an earnings quality tool.

Stochastic and Worst-Case Generalized Sorting Revisited

description: The \emph{generalized sorting problem} is a restricted version of standard comparison sorting where we wish to sort $n$ elements but only a subset of pairs are allowed to be compared. Formally, there is some known graph $G = (V, E)$ on the $n$ elements $v_1, \dots, v_n$, and the goal is to determine the true order of the elements using as few comparisons as possible, where all comparisons $(v_i, v_j)$ must be edges in $E$. We are promised that if the true ordering is $x_1 < x_2 < \cdots < x_n$ for $\{x_i\}$ an unknown permutation of the vertices $\{v_i\}$, then $(x_i, x_{i+1}) \in E$ for all $i$: this Hamiltonian path ensures that sorting is actually possible. In this work, we improve the bounds for generalized sorting on both random graphs and worst-case graphs. For Erdős-Renyi random graphs $G(n, p)$ (with the promised Hamiltonian path added to ensure sorting is possible), we provide an algorithm for generalized sorting with an expected $O(n \log (np))$ comparisons, which we prove to be optimal for query complexity. This strongly improves over the best known algorithm of Huang, Kannan, and Khanna (FOCS 2011), which uses $\tilde{O}(\min(n \sqrt{np}, n/p^2))$ comparisons. For arbitrary graphs $G$ with $n$ vertices and $m$ edges (again with the promised Hamiltonian path), we provide an algorithm for generalized sorting with $\tilde{O}(\sqrt{mn})$ comparisons. This improves over the best known algorithm of Huang et al., which uses $\min(m, \tilde{O}(n^{3/2}))$ comparisons.

description: Magneto Raman scattering study of the E$_{2g}$ optical phonons in multi-layer epitaxial graphene grown on a carbon face of SiC are presented. At 4.2K in magnetic field up to 33 T, we observe a series of well pronounced avoided crossings each time the optically active inter Landau level transition is tuned in resonance with the E$_{2g}$ phonon excitation (at 196 meV). The width of the phonon Raman scattering response also shows pronounced variations and is enhanced in conditions of resonance. The experimental results are well reproduced by a model that gives directly the strength of the electron-phonon interaction.
