Global properties of the spectrum of the Haldane-Shastry spin chain

We derive an exact expression for the partition function of the su(m) Haldane-Shastry spin chain, which we use to study the density of levels and the distribution of the spacing between consecutive levels. Our computations show that when the number of sites N is large enough the level density is Gaussian to a very high degree of approximation. More surprisingly, we also find that the nearest-neighbor spacing distribution is not Poissonian, so that this model departs from the typical behavior for an integrable system. We show that the cumulative spacing distribution of the model can be well approximated by a simple functional law involving only three parameters.Comment: RevTeX 4, 7 pages, 4 figures.

Eastern and Western Promises in Jonathan Franzen's Freedom

ABSTRACT: This essay examines Jonathan Franzen’s novel Freedom (2010) and explores the symbolic way in which this novel uses the urban and regional spaces/places of the United States. Franzen’s use of space/place is related to Francis Scott Fitzgerald’s The Great Gatsby (1925), as well as to Franzen’s previous novels, his well-known Harper’s essay (1996), and other writings like “A Rooting Interest” (2012) or his memoir The Discomfort Zone (2007), where he scrutinizes his own position as a writer and his attitude towards nature. Franzen’s environmental concerns in the novel are also considered from the perspective of ecocriticism. The conclusion is that following Fitzgerald’s example, Franzen uses the East and West (and the urban locales of the inner city and the suburbs) as a backdrop to explore not only the meanings and interpretations of the word freedom (as has been repeatedly pointed out) but also the hopes and aspirations shared by the people of his country, the different dimensions and contradictions of the amalgam of promises and myths known as the American Dream.RESUMEN: Este artículo analiza la última novela de Jonathan Franzen, Freedom (2010), y explora el modo simbólico en que esta novela usa los espacios regionales y urbanos de los Estados Unidos. Este uso de espacios y lugares se relaciona con The Great Gatsby (1925), de Francis Scott Fitzgerald, así como con las novelas anteriores de Franzen, su ensayo “Perchance to Dream” —conocido como el “Harper’s essay” (1996)— y otros textos como “A Rooting Interest” (2012) y The Discomfort Zone (2007) donde Franzen examina su propia posición como escritor y su actitud hacia la naturaleza. Las preocupaciones medioambientales de Franzen en esta novela se estudian también desde la perspectiva de la ecocrítica. La conclusión es que, inspirado por el ejemplo de Fitzgerald, Franzen usa el Este y el Oeste de los Estados Unidos (así como los espacios urbanos del centro de las ciudades y las zonas residenciales) como telón de fondo desde el que explorar no sólo los significados e interpretaciones de la palabra libertad (como han señalado diversos críticos), sino también las esperanzas y aspiraciones compartidas por los habitantes de su país, las diversas dimensiones y contradicciones de esa amalgama de promesas y mitos conocida como el sueño americano

Effects of positive physical imagined contact in a spanish sample

Intergroup conflict has been present since the beginning of humankind. The fights for territories or power and the discrimination of the other seems a constant in our History. From several fields, it is have shown how the boundaries between groups and cultures and the competitive style of many of these relations set the basis for the emergence of conflict, being each day more obvious due to the Globalisation processes. For this reason, the reduction of prejudice and discrimination has been a main objective for the Intercultural Psychology, which, must create tools for this purpose. This work emphasise the usefulness of one of the most promising tools on this field, the imagined contact, grounded in Intergroup Contact Theory (Brown & Hewstone, 2005; Pettigrew, 1998). This technique allows the reduction of implicit negative attitudes toward outgroups using the imagination of individual interactions with members of an outgroup. In this experiment, it is tested a variant of this kind of contact, the physical imagined contact, as well as we try to demonstrate the existence of an improvement in prejudice reduction, at levels of implicit attitudes, when an imagined positive physical contact is given. The findings could not support statically our hypothesis. We discuss the implications of these results and the possibilities in the development of improvements for this useful tool.O conflito intergrupal tem estado presente desde o começo da civilização. As lutas por territórios ou poder e a discriminação dos outros são uma constante na nossa historia. Desde diversos campos tem sido demostrado como as fronteiras entre os grupos e culturas e o estilo competitivo de muitas de estas relações assentam as bases para o surgimento do conflito, sendo sus efeitos ainda mais óbvios devido aos processos de globalização. Por esta razão, a redução do preconceito e da discriminação tem sido um uma preocupação central para a Psicologia Intercultural, a qual, deve encarregar-se de criar ferramentas encaminhadas a este objetivo. Este trabalho remarca a utilidade de uma das técnicas mais promissoras de este campo, o contato imaginado, baseado na Teoria do Contato Intergrupal (Brown & Hewstone, 2005; Pettigrew, 1998). Esta técnica permite a redução das atitudes implícitas negativas faz aos exo-grupos, utilizando a imaginação de interações individuais com membros de outros grupos. Em este experimento é testada uma variante de este tipo de contato, o contato físico imaginado, assim como trata de demostrar a existência de uma melhora na redução do preconceito no nível das atitudes implícitas quando o contato físico imaginado é percebido como positivo. Os resultados não puderam suportar estatisticamente esta hipóteses. Discutimos estos resultados e as possibilidades no desenvolvimento de melhoras para esta útil ferramenta

Determination of phosphorous oxoanions in pharmaceuticals using non- suppressed ion chromatography

The separation and quantitation of phosphorous oxoanions have been investigated by non-suppressed ion chromatogra- phy (IC) with conductometric detection using a modified gluconate-borate buffer as eluent. Hypophosphite being coeluted with the injection peak, its previous oxidation into phosphate is necessary. The method was applied to the determination of hypophos- phite and phosphate in several pharmaceutical

Quick Analysis of Organic Amendments via Portable X-ray Fluorescence Spectrometry

The determination of heavy metals in soils and organic amendments, such as compost, manure, biofertilizer, and sludge, generally involves the digestion of samples with aqua regia, and the determination of those in the solution using various techniques. Portable X-ray fluorescence (PXRF) has many advantages in relation to traditional analytical techniques. However, PXRF determines the total elemental content and, until now, its use for the analysis of organic amendments has been limited. The objective of this work is the calibration of a PXRF instrument to determine the aqua regia-soluble elemental contents directly in solid samples of organic amendments. Our proposal will avoid the digestion step and the use of other laboratory techniques. Using a training set of samples, calibration functions were obtained that allow the determination of the aqua regia-soluble contents from the PXRF readings of total contents. The calibration functions (obtained by multiple linear regression) allowed the quantitative determination of the aqua regia-soluble contents of Fe, K, P, S, Zn, Cu, Pb, Sr, Cr, and Mn, as well as the organic matter content and a semi-quantitative assessment of Al, Ca, V, Ba, Ni, and As contents. The readings of Si, Fe, Al, Ca, K, or S were used as correction factors, indicating that the calibrations functions found are truly based on the chemical composition of the sample matrix. This study will allow a fast, cheap, and reliable field analysis of organic amendments and of other biomass-based materials.Spanish Ministry of Science, Innovation and Universities, and the European Regional Development Fund, European Union, (AEI/FEDER, UE), grant number CGL2016-78937-R

Las evaluaciones externas y el rendimiento académico de los alumnos como instrumento de mejora educativa

El presente artículo refleja la importancia que han adquirido las evaluaciones externas como instrumento de control, por parte de las Administraciones, del estado general de los sistemas educativos. Aunque es un tema de actualidad, la utilización de pruebas externas estandarizadas es tan antigua como los propios sistemas educativos, girando ya desde el inicio en torno al rendimiento académico de los alumnos. En la actualidad esas pruebas sirven de guía para la elaboración de leyes educativas que sin duda, están consiguiendo una auténtica renovación pedagógica en la que las instituciones educativas tratan de obtener los mejores resultados en el rendimiento de sus alumnos, suponiendo todo ello, la mejora general de los sistemas educativosThis article shows the importance of the external evaluation employed by the Administration as a tool to supervise the overall status of the educational system. Being a current issue, the use of a standardised external test is, however, as old as educational systems themselves which since their origin have always been related to students´academic performance. Currently, these tests serve as a guidance to elaborate educational laws that are undoubtedly acquiring an authentic pedagogical renewal through which educational institutions attempt to obtain the best results of their students´ performance and, consequently, the general improvement of the educational syste
