Does functional soil microbial diversity contribute to explain within-site plant beta-diversity in an alpine grassland and a <i>dehesa</i> meadow in Spain?

Questions: Once that the effects of hydrological and chemical soil properties have been accounted for, does soil microbial diversity contribute to explain change in plant community structure (i.e. within-site beta-diversity)? If so, at which spatial scale does microbial diversity operate? Location: La Mina in Moscosa Farm, Salamanca, western Spain (dehesa community) and Laguna Larga in the Urbión Peaks, Soria, central-northern Spain (alpine grassland). Methods: The abundance of vascular plant species, soil gram-negative microbial functional types and soil chemical properties (pH, available phosphorus, and extractable cations) were sampled at both sites, for which hydrological models were available. Redundancy analysis (RDA) was used to partition variation in plant community structure into hydrological, chemical and microbial components. Spatial filters, arranged in scalograms, were used to test for the spatial scales at which plant community structure change. Results: In the case of the dehesa the diversity of soil gram-negative microbes, weakly driven by soil pH, contributed to a small extent (adj-R2 = 2%) and at a relative medium spatial scale to explain change in plant community structure. The abundance of a few dehesa species, both annual (Trifolium dubium, Vulpia bromoides) and perennial (Poa bulbosa, Festuca ampla), was associated with either increasing or decreasing soil microbial diversity. In the alpine meadow the contribution was negligible. Conclusions: Microbial diversity can drive community structure, though in the hierarchy of environmental factors structuring communities it appears to rank lower than other soil factors. Still, microbial diversity appears to promote or restrain individual plant species. This paper aims to encourage future studies to use more comprehensive and insightful techniques to assess microbial diversity and to combine this with statistical approaches such as the one used here

Diversity and the Energy Trilemma. The Case of India (1990-2014)

292 p.How to ensure reliable energy supply and provide universal and affordable access while fighting climate change? Is the exclusive use of renewable sources the solution or is it better to maintain a diverse energy mix? This thesis uses diversity as a key indicator in the analysis of the energy trilemma using a new econometric model. The research reveals the importance of using an inclusive approach and the pertinence of the new model developed after observing, for the selected country and the period studied, thought-provoking changes in the results of the individual and joint analyses, both in the importance and in the sign of this indicator.¿Cómo asegurar un suministro de energía fiable y garantizar el acceso universal y asequible al tiempo que se lucha contra el cambio climático? ¿Es el uso exclusivo de las fuentes renovables la solución o es mejor mantener una matriz energética diversa?

Political Polarisation and Network Leaderships in the Catalan Parliamentarians Twitter Network

This article seeks to test if Twitter is opening communication flows between parties and paving the way for the appearance of network leaderships or if it is reducing them to representatives of the same party or ideology and empowering party leaders. The study is based on a dataset spanning from 1 January 2013 to 31 March 2014 which covers all relationships (4,516), retweets (6,045) and mentions (19,507) of Catalan parliamentarians. The data sustain that the political polarisation of Catalan parliamentarians¿ Twitter flows is deeper in the relationship and retweet networks than it is in the mention and that even if party leaders are still at the centre of communication flows, other parliamentarians are taking the floor and becoming network leaders.Este artículo trata de probar si Twitter abre flujos de comunicación entre partidos distintos y allana el camino para la aparición de liderazgos en la red o si los reduce a representantes del mismo partido o ideología y empodera a los líderes del partido. El estudio se basa en un conjunto de datos que abarca desde 1 de enero de 2013 al 31 de marzo de 2014 e incluye todas las relaciones (4516), retweets (6045) y menciones (19.507) de los parlamentarios catalanes. Los datos sostienen que la polarización política de los parlamentarios catalanes en los intercambios de Twitter es más profunda en las redes de relaciones y las redes de retweets que en las redes de menciones y que, aunque los líderes del partido se encuentran todavía en el centro de los flujos de comunicación, otros parlamentarios están tomando la palabra y se están convirtiendo en líderes en la red

Echo Chambers in Parliamentary Twitter Networks:The Catalan Case

Social media is transforming relations among members of parliaments, but are members taking advantage of these new media to broaden their party and ideological communication environment, or they are mainly communicating with other party members and ideologically aligned peers? This article tests whether parliamentarians’ use of Twitter is opening communication flows or confining them to representatives of the same party or ideology. The study is based on a data set spanning the period January 1, 2013, to March 31, 2014, which covers all relations (4,516), retweets (6,045), and mentions (19,507) among Catalan parliamentarians. Our results indicate that communication flows are polarized along party and ideological lines. The degree of polarization of this network depends, however, on where the interactions occur: The relations network is the most polarized; cross-party and cross-ideological interactions are greater in the retweet network and most present in the mention network

Psychometric analysis of child language pragmatic aspect evaluation: icra-a battery

ResumenEl estudio que se informa describe el análisis psicométrico de la validación y confiabilidad de los instrumentos que conforman la Batería ICRA-A (Investigación de la Competencia Comunicativa para la Realización de Actos de Habla - Abraham & Brenca, 2002, 2005, 2007, 2009a, 2013), la cual fue diseñada para evaluar sistemáticamente el aspecto pragmático del lenguaje infantil en el marco de la evaluación neurolingüística. La batería está conformada por cuatro instrumentos: (1) Análisis y Registro de Actos de Habla, (2) Observación Pragmática del Juego, (3) Cuestionario para Padres y (4) Guía para Padres. Fueron evaluados 155 niños, 100 de ellos tenían compromisos del lenguaje no verbal y/o verbal, y 55, con desarrollo típico del lenguaje. Se realizó el análisis de la validez de constructo utilizando Análisis Factorial con Componentes Principales y Rotación Varimax, la confiabilidad entre jueces, aplicando Coeficiente de Correlación Intraclase con acuerdo absoluto y la consistencia interna, mediante el coeficiente de Alpha de Cronbach. Se determinaron percentiles y valores de corte empleando la Curva ROC, como así también valores de especificidad, sensibilidad, predictibilidad y razón de probabilidad. La validez de constructo para el instrumento 1 fue igual a 65.5% y para el instrumento 2, igual a 73.7 % y la correlación intraclase fue igual a .90 y .89 respectivamente. Los resultados de la Curva ROC fueron: .92 para el instrumento 1 y .89 para el 2. Para el instrumento 1, el valor de sensibilidad fue igual a 81%, el de especificidad 90.9%, de seguridad (VP + 94.2%; VP - 72.5%) y de predictibilidad (CP + 8.47; CP - .21). Los instrumentos 3 y 4 brindan información preponderantemente cualitativa, ya que registran la percepción que tiene cada uno de los padres sobre la competencia comunicativa del niño. Los resultados obtenidos muestran la fortaleza de la Batería ICRA-A para evaluar el aspecto pragmático del lenguaje infantil en la clínica fonoaudiológica.In this paper we describe the psychometric analysis of the validation and reliability of the instruments which constitute ICRA-A Battery (Communicative Competence for Speech Acts Production Research - Abraham & Brenca, 2002, 2005, 2007, 2009a, 2013). It was designed for systematic assessment of child language pragmatic aspect, with a progression criterion, within the framework of neurolinguistic evaluation, in River Plate Spanish speeking children. In this way, it allows to register and analyze pragmatic development rigorously, with variables control, what is added to the analysis made in the other dimensions (phonological, lexical-semantic and morphosyntactic), so permitting to get a whole profile of the child linguistic competence. ICRA-A Battery is applied to little children who show pragmatic impairment. It is also useful with older children with a lower communicative or intellectual range. It is composed of four instruments. (1) Speech Acts Analysis and Register: it allows to evaluate in a quantitative and a qualitative mood pre and paralinguistic manifestations of the seven speech acts basic in children language development. (2) Playing Pragmatic Observation: information can be obtained about communicative competence, fundamentally non verbal, taking into consideration shared referenciality, protodeclaring and protoimperative conducts, prelinguistic functions, basic speech acts precursors, ludic interaction type and mode, analyzed into six communicative dimensions. (3) Parents Questionnaire: useful to get information on the perception each parent has about his / her child communicative competence. (4) Parents Guide: to give parents guidance on their child communicative behavior in three daily routines within the familiar context. ICRA-A Battery includes created ad hoc concrete and figurative material, as well as Register and Results forms. It is incorporated into the ICRA Method, which, from a systematic and progressive fashion, allows to formulate the pragmatic objectives of treatment plan and intervention strategies. One hundred and fifty five children were assessed: 100 with verbal and/or non verbal language impairment, and 55 with normal language development. Construct validity analysis was made through Factorial Analysis with Principal Components and Varimax Rotation. For reliability between judges we applied Intraclass Correlation Coefficient with absolute agreement; and internal consistency through Cronbach Alpha - Coefficient. Percentiles and cut values were determined through ROC Curve, and so specificity, sensibility, predictability values and probability ratio. Construct validity for instrument 1 was of 65.5%; for 2, of 73.7%; intraclass correlation was of .90 and .89, respectively. ROC Curve results were of .92 for instrument 1 and .89 for 2. For instrument 1, sensitivity value was of 81%, specificity of 90.9%,security (VP + 94.2%; VP - 72.5%); predictability (CP + 8.47; CP - .21). Instruments 3 and 4 give a preponderantly qualitative information, as they register the perception that each parent has on their child communicative competence. These results show the Battery ICRA-A fortitude to evaluate the child language pragmatic aspect in phono-audiological work. Speech acts systematic study is a relevant tool in phonoaudiological treatment to obtain greater precision in language analysis of children with communicative competence development difficulties, in differential diagnosis and consequent treatment. The psychometric results that have been achieved show ICRA-A Battery fortitude for its use in the phonological work with neurolinguistic orientation.Fil: Abraham, Maria del Valle.

Querying a Polynomial Object-Relational Constraint Database in Model-Based Diagnosis

Many papers related to Constraint Databases (CDBs) theories exist, including proposals that present frameworks for the treatment of constraints as a new data type. Our proposal presents a new way of storing and manipulating constraints as a usual data, and of making queries about the constraint variables derived from an Object-Relational Constraint Database (ORCDB). In this work, the constraints stored in an ORCDB are only polynomial equality constraints. The proposal is based on Gr¨obner bases, constraint consistency and constraint optimisation techniques. Most works in CDB use spatial-temporal data as a case study, however this work presents an emergent engineering domain, that of fault diagnosis.Ministerio de Ciencia y Tecnología DPI2003-07146-C02-0
