Global relativistic folding optical potential and the relativistic Green's function model

Optical potentials provide critical input for calculations on a wide variety of nuclear reactions, in particular, for neutrino-nucleus reactions, which are of great interest in the light of the new neutrino oscillation experiments. We present the global relativistic folding optical potential (GRFOP) fits to elastic proton scattering data from C-12 nucleus at energies between 20 and 1040 MeV. We estimate observables, such as the differential cross section, the analyzing power, and the spin rotation parameter, in elastic proton scattering within the relativistic impulse approximation. The new GRFOP potential is employed within the relativistic Green's function model for inclusive quasielastic electron scattering and for (anti) neutrino-nucleus scattering at MiniBooNE kinematics.

Realized Matrix-Exponential Stochastic Volatility with Asymmetry, Long Memory and Spillovers

The paper develops a novel realized matrix-exponential stochastic volatility model of multivariate returns and realized covariances that incorporates asymmetry and long memory (hereafter the RMESV-ALM model). The matrix exponential transformation guarantees the positivedefiniteness of the dynamic covariance matrix. The contribution of the paper ties in with Robert Basmann’s seminal work in terms of the estimation of highly non-linear model specifications (“Causality tests and observationally equivalent representations of econometric models”, Journal of Econometrics, 1988, 39(1-2), 69–104), especially for developing tests for leverage and spillover effects in the covariance dynamics. Efficient importance sampling is used to maximize the likelihood function of RMESV-ALM, and the finite sample properties of the quasi-maximum likelihood estimator of the parameters are analysed. Using high frequency data for three US financial assets, the new model is estimated and evaluated. The forecasting performance of the new model is compared with a novel dynamic realized matrix-exponential conditional covariance model. The volatility and co-volatility spillovers are examined via the news impact curves and the impulse response functions from returns to volatility and co-volatility.

Continuidades y rupturas en el proceso de centralización de la administración sanitaria argentina (1880-1945)

El objetivo del trabajo es presentar el proceso de centralización administrativa de la repartición sanitaria nacional. Para ello se analizan, en primer lugar y con la intención de situar el problema en un plazo más largo, los límites que debió afrontar el Departamento Nacional de Higiene desde el momento de su creación, en 1880, para avanzar en sus intenciones centralizadoras. Entre ellos se encuentran su escasa autonomía administrativa, las superposiciones jurisdiccionales con otras dependencias del Estado, las indefiniciones respecto de su supremacía jerárquica, la resistencia de las provincias, los municipios fuertes y las asociaciones benéficas y los conflictos de proyectos al interior mismo de la repartición. En segundo lugar se muestra cómo los sucesivos presidentes del Departamento Nacional de Higiene asumieron ese límite para su gestión y apostaron a la organización interna de la repartición antes que al desafío de la centralización de la asistencia sanitaria. Su estrategia fue el fortalecimiento de nuevas áreas de incumbencia que constituyeron una agenda que sirvió como base de la definitiva centralización de la administración sanitaria. En esta tarea contaron con el apoyo parlamentario, fundamentalmente de la bancada socialista, que logró convertir en ley durante los años 30 a una serie de nuevas atribuciones del Departamento en aspectos que ligaban la salud con la asistencia social. Por último se analiza un momento clave de este proceso, el primer ensayo de centralización sanitaria a través de la creación, en 1943, de la Dirección Nacional de Salud Pública y Asistencia Social.

The Use of Almost Linear Phase IIR filters In DFT Modulated Filter Banks for Communication Systems

This paper is on the use and performance of M-path polyphase Infinite Impulse Response (IIR) filters for channelisation, conventionally where Finite Impulse Response (FIR) filters are preferred. This paper specifically focuses on the Discrete Fourier Transform (DFT) modulated filter banks, which are known to be an efficient choice for channelisation in communication systems. In this paper, the low-pass prototype filter for the DFT filter bank has been implemented using an M-path polyphase IIR filter and we show that the spikes present at the stopband can be avoided by making use of the guardbands between narrowband channels. It will be shown that the channelisation performance will not be affected when polyphase IIR filters are employed instead of their counterparts derived from FIR prototype filters. Detailed complexity and performance analysis of the proposed use will be given in this article.

Fieldworks from the Museum of the Void: Experiments in the Event of an Archive

This exhibition was a research presentation of works made at Center for Land Use Interpretation [CLUI]base in Wendover, Utah, USA between 2008-2010. The project was commissioned by the Centre For Land Interpretation in USA and funded by The Henry Moore Foundation in the UK. Documentation of research conducted in the field as made available as video and installation. An experimental discourse on the preservation of land art was put with GPS drawings and research information displayed as maps and documents. In examining physical sites in Utah, USA, the project connected to contemporary discourse centred on archives in relation to land art and land use. Using experimental processes conceived in relation to key concepts such as event structures and entropy, conceptual frameworks developed by Robert Smithson (USA) and John Latham (UK), the 'death drive' of the archive was examined in the context of a cultural impulse to preserve iconic works. The work took items from Lathams archive and placed them at the canonical 'Spiral Jetty', Smithson land art work at Rozel Point north of Salt Lake City. This became a focus for the project that also highlighted the role of the Getty Foundation in documenting major public artworks and CLUI in creating an American Land Museum. Work was created in the field at extreme remote locations using GPS technologies and visual tools were developed to articulate the concepts of the artists discussed, to engage the exhibition audience in ideas of transformation and entropy in art. Audiences were encouraged to sign a petition to be used in future preservation of spiral jetty currently facing development challenges.

The Collusion of Feminist and Postmodernist Impulses in E.L. Doctorow’s "Ragtime"

Many critics of Doctorow have classified him as a postmodernist writer, acknowledging that a wide number of thematic and stylistic features of his early fiction emanate from the postmodern context in which he took his first steps as a writer. Yet, these novels have an eminently social and ethical scope that may be best perceived in their intellectual engagement and support of feminist concerns. This is certainly the case of Doctorow’s fourth and most successful novel, Ragtime. The purpose of this paper will be two-fold. I will explore Ragtime’s indebtedness to postmodern aesthetics and themes, but also its feminist elements. Thus, on the one hand, I will focus on issues of uncertainty, indeterminacy of meaning, plurality and decentering of subjectivity; on the other hand, I will examine the novel’s attitude towards gender oppression, violence and objectification, its denunciation of hegemonic gender configurations and its voicing of certain feminist demands. This analysis will lead to an examination of the problematic collusion of the mostly white, male, patriarchal aesthetics of postmodernism and feminist politics in the novel. I will attempt to establish how these two traditionally conflicting modes coexist and interact in Ragtime.

Positronium collisions with rare-gas atoms

We calculate elastic scattering of positronium (Ps) by the Xe atom using the recently developed pseudopotential method (Fabrikant and Gribakin 2014 Phys. Rev. A 90 052717) and review general features of Ps scattering from heavier rare-gas atoms: Ar, Kr and Xe. The total scattering cross section is dominated by two contributions: elastic scattering and Ps ionization (break-up). To calculate the Ps ionization cross sections we use the binary-encounter method for Ps collisions with an atomic target. Our results for the ionization cross section agree well with previous calculations carried out in the impulse approximation. Our total Ps–Xe cross section, when plotted as a function of the projectile velocity, exhibits similarity with the electron-Xe cross section for the collision velocities higher than 0.8 a.u., and agrees very well with the measurements at Ps velocities above 0.5 a.u.

Estudo Preliminar de Adaptação e Validação da Escala de Avaliação do Eu Resiliente: resiliência, autodano e ideação suicida em adolescentes

Introdução: Em Portugal, são escassos os instrumentos validados para a população adolescente, que avaliem o importante construto da resiliência. Assim, o principal objetivo deste estudo consistiu na adaptação e validação preliminar da Escala de Avaliação do EU Resiliente (EAER) para adolescentes portugueses. Como segundo objetivo pretendemos, ainda, explorar as associações, na mesma amostra, entre a resiliência, o autodano e a ideação suicida na adolescência. Método: A amostra foi constituída por 226 adolescentes (sexo masculino, n = 139, 61,5%), entre os 12 e os 18 anos, que preencheram um protocolo composto por um questionário sociodemográfico, pela Escala de Avaliação do EU Resiliente (EAER), pelo Questionário de Impulso, Autodano e Ideação Suicida na Adolescência (QIAIS-A) e pela Escala de autoconceito. Resultados: Os resultados obtidos mostraram que a EAER possui boa fidelidade/consistência interna (α = 0,857) e boa estabilidade temporal (r = 0,720). Uma análise de componentes principais mostrou que a EAER apresenta três fatores: fator suporte externo, fator forças pessoais internas e fator estratégias de coping. Encontraram-se correlações negativas entre a resiliência e o autodano e ideação suicida e correlações positivas entre a resiliência e o autoconceito, confirmando-se a validade divergente e convergente da EAER. Verificaram-se níveis elevados de resiliência nos adolescentes da nossa amostra (M = 58,69; DP = 6,67). Na amostra total, 61,5% (n = 139) apresentou ideação suicida e 26,5% (n = 60) apresentou comportamentos de autodano. Conclusão: No seu conjunto, a EAER possui boas características psicométricas, pelo que pode ser considerada uma escala válida e útil e que pode ser usada com segurança na avaliação da resiliência em adolescentes portugueses. Com este estudo alargámos o leque de instrumentos válidos para a medição da resiliência em adolescentes e contribuímos para o avanço da investigação na área da adolescência em Portugal. / Introduction: In Portugal, there are few validated instruments to the adolescent population, to assess the important construct of resilience. Thus, the main objective of this study was the preliminary adaptation and validation of the Escala de Avaliação do EU Resiliente (EAER) to Portuguese adolescents. As a second objective, there is an intention to also explore the associations, on the same sample, between resilience, self-harm and suicidal ideation in adolescence. Method: The sample consisted of 226 adolescents (male, n = 139, 61.5%), between 12 and 18 years, who filled in a protocol consisting of a sociodemographic questionnaire, by the Escala de Avaliação do EU Resiliente (EAER), by the Impulse, Self-harm and Suicide Ideation Questionnaire for Adolescents (ISSIQ-A) and by the Self-concept Scale. Results: The results showed that the EAER has good fidelity/internal consistency (α = 0.857) and good temporal stability (r = 0.720). A principal component analysis showed that EAER has three factors: external support factor, internal personal strengths factor and coping strategies factor. There were negative correlations between resilience and the self-harm and suicidal ideation and positive correlations between resilience and self-concept, confirming the divergent and convergent validity of EAER. There were high levels of resilience in the adolescents of the sample (M = 58.69, SD = 6.67). In the total sample, 61.5% (n = 139) had suicidal ideation and 26,5% (n = 60) had self-harm behaviors. Conclusion: As a whole, the EAER has good psychometric properties, therefore it can be considered a valid and useful range, and can be safely used in the evaluation of resilience in Portuguese adolescents. With this study we have extended the range of valid instruments for the measurement of resilience in adolescents and contributed to the advance of research in the adolescence area in Portugal.

Mapeando fundamentos do Constructo Neuromarketing com profissionais de empresa de publicidade

This study aims to acknowledge the domain level and influence of the neuromarketing construct. This is done considering professionals at advertising agencies in Brazil. The presence of concepts related to this new approach is very little divulged, and there are little analysis performed on this area. Thus, the research is of qualitative and exploratory nature and used as primary fonts books, articles related to marketing, neuroscience, and psychology as well as secondary fonts. A profound interview was realized aiming the main advertising agencies in Brazil. The public was composed by managers responsible for planning. A content analysis was performed afterwards. The advances related to the brain science have permitted the development of technological innovation. These go primarily towards knowledge and unconscious experiences of consumers, which are responsible for the impulse of decision making and consumer behavior. These issues are related to Neuromarketing, that in turn, uses techniques such as FMRI, PET and FDOT. These scan the consumer s brain and produces imagines on the neuron s structures and functioning. This is seen while activities such as mental tasks for the visualization of brands, images or products, watching videos and commercials are performed. It is observed that the agencies are constantly in search of new technologies and are aware of the limitations of the current research instruments. On the other hand, they are not totally familiar with concepts related to neuromarketing. In relation to the neuroimage techniques it is pointed out by the research that there is full unawareness, but some agencies seem to visualize positive impacts with the use of these techniques for the evaluation of films and in ways that permit to know the consumer better. It is also seen that neuroimage is perceived as a technique amongst others, but its application is not real, there are some barriers in the market and in the agencies itself. These barriers as well as some questioning allied to the scarce knowledge of neuromarketing, make it not possible to be put into practice in the advertising market. It is also observed that even though there is greater use of neuromarketing; there would not be any meaningful changes in functioning and structuring of these agencies. The use of the neuro-image machines should be done in research institutes and centers of big companies. Results show that the level of domain of the neuromarketing construct in the Brazilian advertising agencies is only a theoretical one. Little is known of this subject and the neurological studies and absolutely nothing of neuroimage techniques

Das Bistum Würzburg 8. Die Würzburger Bischöfe von 1684–1746

Im fünften Band der Würzburger Bischofsreihe der Germania Sacra behandelt Winfried Romberg die Episkopate der Epoche vom Spätkonfessionalismus katholischer Provenienz bis zum Einsetzen erster Impulse der Aufklärung. Neben der ständigen Herausforderung in der Reichs- und äußeren Politik war das Zeitalter geprägt vom verstärkten ordnungspolitischen Aufbau der weltlichen und geistlichen Landesverwaltung wie in religiös-ästhetischer Hinsicht vom Kirchenbarock und seinen Frömmigkeitsformen. Die vorgestellten fünf Pontifikate illustrieren den in diesem Zeitraum erreichten Höhepunkt absolutistischer Machtentfaltung einschließlich verwandter merkantilistischer Prinzipien. Die beiden Pontifikate der Schönborn-Brüder Johann Philipp Franz und Friedrich Carl markieren hierbei den Zenit dieses einflussreichen rheinisch-fränkischen Adelsgeschlechts im Hochstift Würzburg. Insgesamt fand das Würzburger Staatswesen in dieser Periode zu festen Formen, die auch im weiteren 18. Jahrhundert erhalten bleiben sollten.

The (Im)possibility of the Intellectual Worker Inside the Neoliberal University

The provocation and point of this paper is that universities of the North during the era of neoliberalism of have been sucked of their human life-giving capacities. What remains are closed doors and bare walls. Lest we give the impression of a hopelessly romantic view of the university (and embark upon a lament for some paradise lost), let us be clear from the outset: there is no such place – and there never has been. As will be outlined below, a consideration of the history of the university reveals it was born and has persistently drawn its life breath from oxygen formed in the tension ridden mix of an impulse to human freedom and accommodation to powers of church, state and capital. But, we contend, history is now the witness to the almost complete dissolution of that tension: to the exhaustion of emancipatory impulses in the service of indoctrination, regulation and accumulation. In the church-state-capital triad, it is the latter that has emerged hegemonic. Importantly, we argue, its dominance has emerged with the rise of what Paul Baran and Paul Sweezy describe as monopoly capital: the move from competitive (small entrepreneurial business) forms to monopolistic (large corporate business) regimes of accumulation (Baran & Sweezy 1966). A central feature of monopoly capitalism is its need for significant financial support of national states and the harnessing of public resources such as universities to feed accumulation. It is no surprise that neoliberalism, despite its neoclassical economic pronouncements, is a ‘big state’ advocate (Harvey 2005). Our argument is that neoliberalism, as the political workhorse of monopoly capitalism, has overseen a makeover of universities so they might behave like a monopoly capitalist corporation. Our time is the time of the near global domination of capital. The university has succumbed. In its colonisation – its capitalisation – the university has not only reinvented itself as a willing ally of capital but has also set about remaking itself in its image.

Palkitsemisen vaikutus kaupan alan myymälähenkilökunnan työmotivaatioon ja työsuoritukseen

Palkitseminen on yksi keskeisimmistä työmotivaatioon ja työsuoritukseen vaikuttavista elementeistä. Tässä kvalitatiivisella tutkimusmenetelmällä laaditussa Pro gradu-tutkielmassa tutkitaan palkitsemisen vaikutusta kaupan alan myymälähenkilökunnan työmotivaatioon ja työsuoritukseen. Tutkimuksen tavoitteena on selvittää millä tutki-muksen kohdeorganisaation nykyisillä kokonaispalkitsemisen keinoista on merkittävin vaikutus myymälähenkilökunnan työmotivaatioon ja työsuoritukseen. Lisäksi tutkimus havinnollistaa, millaisilla muilla palkitsemisen keinoilla pystytään vaikuttamaan myymälähenkilökunnan työmotivaatioon siten, että sen vaikutus heijastuu positiivisena impulssina myös työntekijän työsuoritukseen. Tutkimuksen teoreettinen viitekehys on rakennettu kokonaispalkitsemisen ja työmotivaation ympärille ja näkökulmia peilataan sekä yksilön kokeman oikeudenmukaisuuden, että yrityksen strategisen palkitsemisen näkökulmista. Tutkimuksen perusteella voidaan nähdä, että tulokseen sidottu palkitseminen on yksi keskeisimmistä työsuoritukseen vaikuttavista palkitsemisen elementeistä myyntityössä. Työsuoritukseen ja työmotivaatioon pystytään vaikuttamaan myös itsenäisellä työskentelytavalla, uramahdollisuuksilla ja ammatillisen kehittymisen mahdollisuuksilla. Kohdeorganisaation kokonaispalkitsemisen mallia tulisikin muokata vastaamaan entistä paremmin näitä indikaattoreita, jotta kokonaispalkitsemisen malli toimisi strategisen palkitsemisen näkökulmasta mahdollisimman optimaalisella tavalla.
