Notion de $θ$-régulateurs d'un nombre algébrique. Conjectures p-adiques

description: Let K/Q be a Galois extension of degree n, of Galois group G, and let $η\in K^\times$. For all large enough prime p, we define, by use of the Frobenius theorem on group determinants, the family $(Δ_p^θ(η) \in \F_p)_θ$ of local $θ$-regulators of $η$, indexed by the Qp-irreducible characters $θ$ of G. At each $Δ_p^θ(η)$ is associated a linear representation $L^θ\simeq δV_θ$, $0 \leq δ\leq φ(1)$, which characterizes some properties of $Δ_p^θ(η)$, including its nullity equivalent to $δ\geq 1$ (Th. 3.11). When $η\in \Q^\times$ and $θ= 1$, $Δ_p^1 (η)$ is the p-Fermat quotient of $η$. When $η$ is a "Minkowski unit", each $Δ_p^θ(η)$, $θ\ne 1$, gives the residue modulo p of the $θ$-component of $p^{1-n} Reg_p (K)$, where Reg(K) is the classical p-adic regulator of K. We suggest that the "probability" of ($Δ_p^θ(η) = 0$ and $L^θ\simeq δV_θ$) is $\frac{O(1)}{p^{f δ^2}}$, where f is a suitable residue degree of p. We conjecture that $p^{1-n} Reg_p(K)$, which measures the order of the p-torsion group in Abelian p-ramification over K, is for p large enough a p-adic unit except perhaps for a set of prime numbers of zero density. For these cases said "of minimal p-divisibility" (Def. 3.17), it remains possible, $η$ being then a "partial local pth power" at p, to propose, in connection with the ABC conjecture, a stronger conjecture leading to the same conclusion for all large enough p (Section 7). Some other conjectural aspects on the Fermat quotient are discussed. We precise and verify these properties through numerical studies on various fields and publish the corresponding "PARI" programs.

Methods for the Production of Lithium Carbonate from Lipidolite
Creators: name: Hopper, Basil

Year: 1923
Subjects: subject: Chemical Engineering
subject: FOS: Chemical engineering

description: [Introduction] The object of this investigation has been to determine a method to extract lithium from its ores in order to produce Li2CO3 which is used in medicine.  Lithium salts command very good prices (averaging about $1.50 per pound) and a simple method of production would form a successful commercial enterprise.  Lithium occurs in lepidolite (a lithium mica) and in amblygonite and other moderately rare minerals.  In Southern California there are deposits of lepidolite with which this work has been conducted.

The metal belongs to the alkali group but shows many properties characteristic of the alkaline-earths.  It acts vigorously with water, hydrogen, nitrogen and oxygen, thus resembling the alkalies.  The relative insolubility of the hydroxide, carbonate and phosphate, makes it resemble the alkaline-earths.  Lithium gives a very characteristic spectrum which makes it easy to test for traces with a hand spectroscope.

description: Durante as últimas décadas, Curitiba tem sido referenciada como uma “cidade modelo” ambientalmente sustentável e um notável exemplo tanto de um processo de planejamento urbano bemsucedido como de uma ampla coleção de projetos de desenho urbano atraentes, inovadores, funcionais, econômicos e replicáveis. Este capítulo examina projetos de desenvolvimento urbano em Curitiba desde os anos 1960 e apresenta várias razões pelas quais a cidade merece louvor: o competente e contínuo processo de planejamento garantiu a eficiência do transporte público, a preservação histórica e cultural, a revitalização do Centro e a prioridade à circulação de pedestres, programas ambientais eficazes e uma série de projetos catalisadores de desenho urbano e arquitetônicos. Este capítulo também discute alguns fatores políticos e institucionais que vieram a facilitar o desenvolvimento do processo de planejamento de Curitiba e alguns problemas recentes de gestão e planejamento urbano que a cidade vem enfrentando. O processo de planejamento de Curitiba foi delineado pela acomodação de diversos interesses em torno de um mesmo projeto político, pela divulgação, por meio da mídia, de uma imagem particular de cidade e pelos ganhos materiais que atingiam as classes menos favorecidas. Reciprocamente, alguns fatores que desafiam o modelo de gestão urbano, ameaçando subverter o futuro de processos de planejamento na cidade, dizem respeito a aumento dos problemas urbanos e das desigualdades entre os municípios da região metropolitana, deficiências da estrutura e coordenação institucional no nível do planejamento e gestão metropolitana e atendimento inadequado das instituições do governo e de planejamento aos crescentes desafios postos por cidadãos que demandam mais responsabilidade e participação política. Aqui, argumentamos que a instituição de uma participação democrática mais efetiva nas tomadas de decisão sobre Curitiba será o meio de legitimar e dar continuidade aos processos urbanísticos que se iniciaram de forma tão brilhante no limiar dos anos 1960 e um registro louvável de sua implementação entre os anos 1970 e início de 1990.

description: This problem concerns itself with the possibility of producing a reasonably pure concentrated caustic soda solution using trona as a starting material.  It involves a carbonation process, purification of raw material and causticization with lime.  Since soda ash costs a little less than three times what trona costs, the process has good commercial possibilities.

description: We present DisCo, a novel display-camera communication system that enables displays to send short messages to digital sensors, while simultaneously displaying images for human consumption. Existing display-camera communication methods are largely based on spatial-domain steganography, where the information is encoded as an imperceptible spatial signal (e.g., QR-code). These methods, while simple to implement, are prone to errors due to common causes of image degradations such as occlusions, display being outside the sensor’s field-of-view, defocus blur and perspective distortion. Due to these limitations, steganography based techniques have not been widely adopted, specially in uncontrolled settings involving consumer cameras and public displays.
Perspectives on Bruckner

description: For decades Anton Bruckner has remained outside the mainstream of American musicological discourse, despite his importance to the late-nineteenth- century symphonic repertoire. But in the rapidly changing era of contemporary musicology, where the modernist curled lip seems to have relaxed a bit, it is perhaps not surprising that even Bruckner should have his moment. That moment was a four-day international symposium in February 1994. Certainly, without confronting its past, Bruckner research cannot make significant strides forward, and during this conference there were some important strides indeed. American Bruckner scholarship is admittedly in an early phase, and in years to come this conference will no doubt be seen as an important turning point. One hopes that it will inspire further studies that explore Bruckner and his music beyond the narrow lens of editorial problems and localized analytical issues, as important as those may be.

We in particular find some operators whose matrix elements in a nucleon of momentum $P^z$ are directly related to $ΔG$ with only power-law $(1/P^z)^n (n\ge 2)$ corrections.

description: Background: Blepharospasm is a focal cranial dystonia, which could be idiopathic in origin or secondary to an underlying disorder that commonly impairs quality of life. Botulinum toxin (BoNT) injections have become the treatment of choice; however, a less favorable response to BoNT is expected in secondary blepharospasm. No studies have been conducted comparing outcomes between blepharospasm cohorts. We therefore aim to compare BoNT outcomes in primary and secondary blepharospasm subjects.

Methods: A retrospective review of 64 blepharospasm subjects receiving BoNT therapy was conducted. Demographics, BoNT treatment schedules, duration of BoNT therapy, and side effects were recorded. Outcome measures were duration of benefit, peak-dose benefit recorded with the Clinical Global Impressions Scale (CGIS), and related side effects.

Results: No difference was found between the two cohorts regarding duration of benefit from treatment (primary 9.47 weeks vs. secondary 9.63 weeks, p = 0.88). Perceived peak-dose benefit was more commonly reported as “very much improved” in secondary patients, but this was not significant (p = 0.13). Higher BoNT dosages were required in both groups over time, with a mean increase of 20.5% in primary and 26.5% in secondary blepharospasm. Ptosis (8%) and diplopia (6%) were the most common reported side effects. Mean follow-up in years was similar between groups, 3.6 years for primary vs. 2.4 years for secondary blepharospasm (p = 0.17).

Discussion: BoNT injections were effective with comparable benefits seen in both primary and secondary blepharospasm populations. Clinicians should be aware of the similar benefit from BoNT reported in secondary blepharospasm patients. The average duration of benefit in this cohort was comparable with previous reports.
The Extraction of Orange Oil with Volatile Solvents

subject: FOS: Chemical engineering

description: Citrus oils are used largely by confectioners, bakers, and manufacturers of soft drinks for flavoring.  In 1916, 98% of the citrus oils used in this country were imported.  The relatively small amount of oils produced here are obtained from the cull fruit by two general methods, the expression or pressure method and by some form of the distillation method, either vacuum distillation of the dry peel or steam distillation under various pressures.  The expression method gives a much superior oil as compared with the oil obtained by distillation.  However the expression method has the disadvantage that a considerable amount of oil is left in the pulp after the squeezing process.  In the plant of the Exchange Orange Products Co. at San Dimas, California, where orange oil is produced, this remaining oil is recovered in a less valuable form by a subsequent steam distillation.

The object of this investigation was to study the method of solvent extraction as a possible means of obtaining all of the oil in a good condition.  A satisfactory solvent was to be found and its use studied as extensively as time permitted.

description: Lutetium-Yttrium Orthosilicate doped with Cerium (LYSO:Ce), as a bright scintillating crystal, is a candidate for calorimetry applications in strong ionizing-radiation fields and large high-energy hadron fluences as are expected at the CERN Large Hadron Collider after the planned High-Luminosity upgrade. There, proton-proton collisions will produce fast hadron fluences up to ~5E14/cm^2 in the large-rapidity regions of the calorimeters. The performance of LYSO:Ce has been investigated, after exposure to different fluences of 24 GeV/c protons. Measured changes in optical transmission as a function of proton fluence are presented, and the evolution over time due to spontaneous recovery at room temperature is studied. The activation of materials will also be an issue in the described environment. Studies of the ambient dose induced by LYSO and its evolution with time, in comparison with other scintillating crystals, have also been performed through measurements and FLUKA simulations.

We argue that the condensation of self-trapped exciton gas starts at the same critical temperature in all traps due to the specific scaling rule. As a consequence of the reduced dimensionality of the system, the scaling parameters appear to be insensitive to disorder.

title: Perfectionism in students and employees : predicting stress and intra group relationships
Creators: name: Childs, Julian H.
Publisher: name: University of Kent
Year: 2022

description: Over the past 20 years, Hewitt and Flett's (1991) tripartite model of perfectionism has been the focus of numerous research studies. Academia and work are two life domains in which perfectionism is most prevalent. Nevertheless, there is a lack of research with samples of students and employees on the longitudinal effects of perfectionism on stress, burnout, and engagement, and on the effects of perfectionism on intragroup relationships in a team-work context. The aims of this thesis were therefore to investigate whether perfectionism longitudinally predicts stress, burnout, and engagement, and to investigate whether perfectionism is associated with intragroup relationships in a team-work context. To this end, I conducted six studies. In Study 1, 76 students completed measures of perfectionism, the Big Five, burnout, and engagement twice over four months. In Study 2, 69 employees completed measures of perfectionism, stress, and burnout twice over six months. In Study 3, 195 teachers completed measures of perfectionism, stress, burnout, and engagement twice over three months. In Study 4, 147 students completed a measure of perfectionism and then responded to a vignette about working with a hypothetical partner who was described as a perfectionist. In Study 5, 110 students working on team projects completed measures of perfectionism, cohesion, and engagement. And in Study 6, 149 employees, nested within teams, completed measures of perfectionism, cohesion, and stress. Across studies, socially prescribed perfectionism consistently predicted higher levels of stress and burnout longitudinally, and it was also associated with positive and negative intragroup relationships. In comparison, self-oriented perfectionism was associated with positive intragroup relationships, and other-oriented perfectionism was associated with positive and negative intragroup relationships. The findings suggest that students and employees who strive for exceedingly high standards experience increasing levels of stress and burnout which may harm their future psychological adjustment.
Centers; Dissenters (Music, Religion, and Politics)

Subjects: Music

description: To explore the question "How can someone create art now?," the essay first sketches a broad historical framework, and continues by peering through a lens made of two concepts: the center, and dissent. It explores the Greek influence (Plato the centrist, Socrates the dissenter; dissent as
apartness, the center as control molded by dissent) and Christianity (dissent in Job, the Fall, and St. Francis). Whereas the dissent of Socrates was the mold filled by Plato's Center, in Christianity the omnipotent, omnipresent God is the mold, Sin and the Fall its negative, dissent molded by
the Center: a double obverse. The essay talks about contemporary music and violence: the beat and
the originary scene (Boulez), other strategies (Xenakis, Cage); commodification; rock promoting the ecstasy of identity and submission; Disneyfication. It explores feminism on violence; critical theory on the subject; the Deleuzian Body Without Organs and Kristeva's chora; and Judith Butler on subjectless agency, signification as a regulated process of repetition. Finally, the essay touches on the relations among dissent, autonomy, agency; superfaciality; insignification; theory as praxis as art as life; and intimate apartness built into the Sichselbstgleichheit of the work of art.

description: À ce jour, l’apiculture occupe une place à part dans l’agriculture biologique, car elle est souvent pratiquée séparément du reste de l’agriculture. Toutefois, l’apiculture biologique est également soumise à des règles claires, basées sur les principes de l’agriculture biologique. En apiculture biologique, il s’agit de favoriser la santé et la vitalité des colonies d’abeilles et de réduire autant que possible l’effet des facteurs environnementaux négatifs grâce à beaucoup de circonspection et de soin. Ce premier objectif exige des connaissances spécialisées sur les besoins et le comportement naturel des abeilles, une bonne observation des colonies et une méthode de travail minutieuse. Cette fiche technique donne un aperçu des principaux principes et méthodes de l’apiculture biologique. Une attention particulière est accordée aux moyens de prévenir les maladies et de lutter contre les ravageurs. La publication s’adresse donc aussi bien aux novices qu’aux apicultrices et apiculteurs souhaitant travailler selon les principes de l’agriculture biologique.

description: Background: Four cases of paroxysmal kinesigenic dyskinesia (PKD) have been reported in individuals with proximal 16p11.2 microdeletions that include PRRT2.
Case Report: We describe a fifth patient with PKD, features of Asperger’s syndrome, and mild language delays. Sanger sequencing of the PRRT2 gene did not identify any mutations implicated in PKD. However, microarray-based comparative genomic hybridization (aCGH) detected a 533.9-kb deletion on chromosome 16, encompassing over 20 genes and transcripts.
Discussion: This case underscores the importance of aCGH testing for individuals with PKD who do not have PRRT2 mutations, particularly when developmental delays, speech problems, intellectual disability, and/or autism spectrum disorder are present.

description: This paper considers the higher derivative terms in the effective action of type II string theory and in particular the behaviour of the automorphic forms they contain in all the different possible limits of the string parameters. The automorphic forms are thought to obey Poisson equations which contain the Laplacian defined on the coset space to which the scalars fields belong and we compute this Laplacian in all the possible string theory limits. We also consider these Poisson equations in the decompactification limit of a single dimension and by making two assumptions, one on the generic form of this equation and the other on the behaviour of the automorphic forms in this limit, we find strong constraints on the allowed form of this differential equation. We show that these constraints allow one to recover much of what was previously known about the automorphic forms corresponding to terms in the effective action that have fourteen or fewer space-time derivatives in a simple way.

description: We consider a simple dynamic model of the vibrating screen operating in the parametric resonance (PR) mode. This model was used in the course of designing and setting of such a screen in LPMC. The PR-based screen compares favorably with conventional types of such machines, where the transverse oscillations are excited directly. It is characterized by larger values of the amplitude and by insensitivity to damping in a rather wide range. The model represents an initially strained system of two equal masses connected by a linearly elastic string. Self-equilibrated, longitudinal, harmonic forces act on the masses. Under certain conditions this results in transverse, finite-amplitude oscillations of the string. The problem is reduced to a system of two ordinary differential equations coupled by the geometric nonlinearity. Damping in both the transverse and longitudinal oscillations is taken into account. Free and forced oscillations of this mass-string system are examined analytically and numerically. The energy exchange between the longitudinal and transverse modes of free oscillations is demonstrated. An exact analytical solution is found for the forced oscillations, where the coupling plays the role of a stabilizer. In a more general case, the harmonic analysis is used with neglect of the higher harmonics. Explicit expressions for all parameters of the steady nonlinear oscillations are determined. The domains are found where the analytically obtained steady oscillation regimes are stable. Over the frequency ranges, where the steady oscillations exist, a perfect correspondence is found between the amplitudes obtained analytically and numerically. Illustrations based on the analytical and numerical simulations are presented.

description: The emission angle and the transverse momentum distributions of projectile fragments produced in fragmentation of $^{56}$Fe on CH$_{2}$, C, and Al targets at 471 A MeV are measured. It is found that for the same target the average value and width of angular distribution decrease with increase of the projectile fragment charge, and for the same projectile fragment the average value of the distribution increases and the width of the distribution decreases with increasing the target charge number. The transverse momentum distribution of projectile fragment can be explained by a single Gaussian distribution and the averaged transverse momentum per nucleon decreases with the increase of the charge of projectile fragment. The cumulated squared transverse momentum distribution of projectile fragment can be well explained by a single Rayleigh distribution. The temperature parameter of emission source of projectile fragment, calculated from the cumulated squared transverse momentum distribution, decreases with the increase of the size of projectile fragment.

Economic feasibility and environmental impact of wireless charging techniques for electric ground fleet in airports
Creators: name: Marques Soares, Laura
Publisher: name: No Publisher Supplied
Year: 2020

description: Balancing environmental, economic, and social issues is challenging for industry sectors and government agencies. According to the Environmental Protection Agency (EPA) of the United States (U.S.), the transportation sector was responsible for 29% of greenhouse gas (GHG) emissions in the U.S. in 2017. Electric mobility is an alternative to mitigate this issue by substituting fossil fuels for electricity. In addition, the use of energy from a renewable source will increase even more environmental benefits. Charging these vehicles can be wireless or wired, stationary, or in-motion. Many airports are converting the conventional ground fleet to electric vehicles to reduce greenhouse gas (GHG) emissions and increase airport operations sustainability. It is necessary to understand the economic feasibility and environmental impacts of this change to justify the decision. This study first used life cycle cost analysis (LCCA) to compare electrified ground fleet’s economic performance compared to conventional fossil fuel option. Three different charging systems (plug-in charging, stationary wireless charging, and dynamic wireless charging) for pushback tractors and inter-terminal buses at a major hub airport were considered in the analysis. Although the conventional fossil fuel options present the lowest initial cost for both fleets, it costs the most in a 30-year analysis period. Among three electric charging infrastructures, the plug-in charging station shows the least accumulative present value of cost. Although the electric ground fleet is proved to show economic benefits, the most cost-effective charging infrastructure may vary depending on driving mileage and system design. The use of LCCA to analyze new systems and infrastructures for decision-making is highly recommended. Life-cycle assessment (LCA) is then used to quantify the environmental impact of electric fleet compared to conventional fossil fuel vehicles. The assessment was analyzed for energy consumption and emission of CO2-eq respectively to assess Cumulative Energy Demand (CED) and Global Warming (GW) potential. The results show that the operation phase outweighs any initial impact from manufacturing and charger construction phases; the operations phase accounts for both the highest CED and GW values. For both pushbacks and buses, the electric options are shown to have very similar impacts. The lower impact option can quickly change depending on the design. On the other hand, the conventional vehicle system presented the highest impact on the two studied categories for both fleets. The discrepancy between conventional buses and all three electric options is even higher on the bus fleet study, suggesting that electric buses are environmentally better than conventional.
The proton spin decomposition : path dependence and gauge symmetry

description: We discuss the different types of decomposition of the proton spin. We stress that, despite their lack of uniqueness, the Chen et al. and Wakamatsu decompositions are perfectly measurable. We argue that a large part of the recent controversies boils down to the fact that there actually exist two types of gauge transformations in the Chen et al. approach, where physical and gauge degrees of freedom of the gauge potential are explicitly separated. By carefully distinguishing these two types of gauge transformations, one can easily understand how the concepts of gauge invariance, Stueckelberg symmetry, path dependence and measurability are linked to each other.

gender were discussed early in the 1980s, especially in work on women,
the conscious and deliberate use of the term itself is even more recent. In
its relatively brief existence, however, gender has had a profound impact
on the field.
The Model of Gas-Discharge Nonneutral Electron Plasma

description: The model of gas-discharge nonneutral electron plasma has been considered, in which the electron density is limited by non-linear processes initiated by diocotron instability and it does not depend on the mechanism of electron transport across the magnetic field. The model describes well the characteristics of electron sheath and the current characteristics of discharge both, in magnetron geometry and in the geometry of inversed magnetron, and it allows us to describe quantitatively the influence of anode misalignment on the discharge electron sheath for the first time. The scope of applicability of the proposed model, as well as its relation with other models of electron sheath is studied.

Musical Pasts and Postmodern Musicologies: A Response to Lawrence Kramer
Creators: name: Tomlinson, Gary
Publisher: name: Columbia University
Year: 1993
Subjects: Music

description: Tomlinson responds to a piece by Lawrence Kramer entitled 'The Musicology
of the Future". According to Tomlinson, 'The Musicology of the Future" seems to linger over old viewpoints more than suggest new ones. It reveals patterns of thought that not only already
threaten to harden into new orthodoxies of postmodern musicology but that have, at the deepest level, moved little from the putative truths they aim to leave behind. What follows is a brief rejoinder to Kramer's vision of the new musicology. He claims, Enough. More than enough. We both, Kramer and I, write books, and have published ones recently that, if not the last words on our approaches,
at least give a clearer sense of their differences in practice than will be had from this exchange. Readers who care to follow these differences might well turn to Music as Cultural Practice and Music in Renaissance Magic.

The Victory of Turan and the Fall of Ērānšahr: Turks and Iranians in the Last Great War of Antiquity

Subjects: subject: Sasanians

subject: Seventh Century
subject: Pre-Islamic Iran
subject: Imperial Ideology
subject: Decline and Fall

description: This paper offers a reexamination of the Iranian Empire’s defeat in the final years of the “Last Great War of Antiquity” (c. 626-30), a blow from which the empire never recovered. It argues for the decisive importance of the Turkic Khaganate’s involvement, suggesting that their impact may be just as key as that of the Romans. Beyond the impressive military power of the Khaganate, an exploration of Iranian imperial ideology reveals that the Turks’ victory represented a subversion of the empire’s very foundations, playing a critical, hitherto underexplored role in its collapse. This approach more fully situates Iran within its Eurasian context and disentangles this terminal period from the coming Islamic conquests. In so doing, it seeks to overturn common teleological assumptions and reckon with broader questions of imperial “decline and fall.”
Cinderella; or Music and the Human Sciences. Unfootnoted Musings from the Margins
Creators: name: Botstein, Leon
Publisher: name: Columbia University
Year: 1993
Subjects: Music

description: It has become fashionable among scholars to wax autobiographical with the reader, presumably to shed any remnant of the illusion (suggested implicitly by the conventional apparatus of a scholarly text and footnotes) that one might be speaking with an objective voice, or with an argument
whose merits can be considered and even accepted without reference to personal and therefore circumstantial prejudice. Today's penchant for presumed full disclosure of one's subjective standpoint, however, is more likely either a species of authorial vanity masquerading as methodological scrupulousness or evidence of a greater interest in oneself than the subject
one is writing about. In this case, the reader who wishes to distill the prejudices of the author and speculate on their origins must begin with the author's notion that one can talk effectively about the character and value of arguments by using procedures of reading and research that hold
up under scrutiny and require no subjective apologetics. Botstein concludes that the definition of future methods of analysis, including the setting of the research agenda, cannot be undertaken from within the current traditions of music history or musicology.

Modeling granulation's effect on stellar line shapes and EPRV surveys with GRASS: The GRanulation and Spectrum Simulator

description: Granulation in the atmospheres of cool stars introduce changes to the shapes of absorption lines distinct from pure Doppler shifts. For stellar astronomers, these line-shape changes (quantified as line bisectors) are useful for studying convective motions in stellar atmospheres. For astronomers who study exoplanets, these changes pose a significant obstacle to the longstanding goal of detecting and characterizing Earth-like exoplanets, even despite advances in radial velocity spectrographs. To further understand how granulation in the atmospheres of Sun-like stars contributes to variability of stellar spectra, we have developed a package (GRASS, the GRanulation And Spectrum Simulator; https://github.com/palumbom/GRASS) which uses very high spectral resolution, spatially-resolved observations of the Sun to empirically model granulation-induced changes in the shapes of stellar lines. We present this program, and evaluate our granulation model against observations of the disk-integrated Sun. We explore how granulation differentially affects lines with differing depth, excitation potential, and magnetic sensitivity. Additionally, we use these results to inform which strategies for mitigating stellar variability are sensitive to granulation-driven variability.

Subjects: Computer science

description: Internet adoption tends to progress in phases: early rapid adoption in urban areas and by relatively well-educated and higher-income households, then transitioning to a slower pace once between 70 and 85% of households subscribe. For example, in a 2013 survey, the Pew Research Internet Project found that approximately 15% of the adult population does not use the Internet; those least likely to use the Internet include “senior citizens, adults with less than a high-school education and those living in households earning less than $30,000 per year.”
Reading and Misreading: Schumann's Accompaniments to Bach's Sonatas and Partitas for Solo Violin
Creators: name: Lester, Joel
Publisher: name: Columbia University
Year: 1994
Subjects: Music

description: The piano accompaniments Robert Schumann wrote for J. S. Bach's solo violin works can be read as a commentary by one major composer on another's works. These accompaniments misread Bach's intentions in obvious ways (e.g., that solo violin is not a viable performance vehicle), and
interpret rhythmic, harmonic, thematic/motivic, and formal structures in a manner clearly at odds with early eighteenth-century conceptions. Comparing these works with Schumann's accompaniments, eighteenth century arrangements of some movements (including some by Bach), and keeping in mind the theoretical frameworks of various eras allows us to gain
insights into how our own stylistic biases affect what we hear in music of past eras.
Unravelling the role of the sport psychologist in talent development
Creators: name: Hinchliffe, Charlotte
Publisher: name: Leeds Beckett University

Subjects: Uncategorized

description: The field of talent development (TD) has benefitted from a burgeoning of research over the last couple of decades, including psychological factors associated with successful TD. However, there is a notable gap in the literature relating to how practitioner sport psychologists can implement this knowledge into their applied practice. To address this research-practice gap, this thesis adopts an action research approach to understand how sport psychologists can go about supporting effective TD of athletes. Within the thesis, I outline the four-stage action research process I undertook as a researcher-practitioner working within a professional men’s rugby league academy. The first stage included a process of planning an evidence-informed and contextually-relevant intervention through exploration of the existing literature to understand what evidence already existed in this area, and interviews with players at the academy to explore their experiences of this developmental stage in their careers. Specifically, I was able to identify demands, resources, and barriers experienced by players during their time in the academy. This information was used to inform the delivery of a solution-focused groupwork intervention to relevant stakeholders (including players, coaches and support staff, and parents) in the next stage of the process. I then went on to observe the impact of the intervention, focusing particularly on any learning and/or change action that had occurred. Finally, I spent time reflecting on how these outcomes had been achieved, through exploring the processes and mechanisms that underpinned the observed learning and change action. Through engaging in this four-stage process, I have been able to deliver real-world impact and positive change within the academy in which I was working, improve my own applied practice as a practitioner sport psychologist, and also produce new knowledge to help bridge the research-practice gap within TD.
What makes top 20 JIF journals "top"?: Exploring characteristics of journals indexed in the Journal Citation Reports

description: The aim of our research is to answer the question why top journals are “top”. This paper presents the results of the first step of our research, in which we investigated whether or not the top journals stand out among 12,323 journals in the JCR 2020 list in terms of various factors such as publishers, citable items. The results showed that top 20 journals stand out in terms of their subject categories and publishers. At this point, it would seem that the subject category is more decisive than the publisher. Considering the Springer Nature example, publishers that stand out in the top 20 have more publishing activities in the subject categories that have more top 20 journals. Although the top 20 journals are located in the highest 5% of all JCR journals in terms of the number of total citations, except five review journals their distribution by citable items differs greatly. Especially for the review journals, the number of citable items is at the lower end of the distribution. It should be noted that more than half of top 20 journals locate as outliers among all journals in terms of the share of articles in citable items. This is mainly due to high density of review journals in top 20. The behaviour of journals regarding cited and citing half-life is different. They generally locate in the boundaries of middle half of all JCR journals in terms of cited half-life. However, they are in the first shortest quartile of citing half-life. Note that the five journals in top 20 from Engineering & Technology and Multidisciplinary subject categories have shortest citing half-life in comparison with the other JCR listed journals in these disciplines. We aim to investigate top 20 journals more deeply in the on-going second step of this research project considering the previous JCR years, and to understand the reasons for the location of top 20 journals among all JCR journals. In this second step, JCR 2020 top 20 journals’ change of ranks, subject categories, and publishers between 1997-2020, types of journals and documents, citation skewness and number of articles that provide impact factor advantage, number of authors and international collaborations, affiliations, and funding information will also be considered.
