Soil Disturbance Increases Soil Microbial Enzymatic Activity in Arid Ecoregions

Functional diversity of the soil microbial community is commonly used in the assessment of soil health as it relates to the activity of soil microflora involved in carbon cycling. Soil microbes in different microenvironments will have varying responses to different substrates, thus catabolic fingerprint information of each location-specific community can be obtained. The purpose of this study was to evaluate total-soil enzymatic activity profiles across three disturbance regimes in an arid desert grassland in the Southwestern United States. Microbial enzymatic activity was measured using the MicroResp™ system, which measures respiration of microbes within whole soil samples supplemented with various carbon sources (simple and polymeric sugars, amino acids, carboxylic acids, and fatty acids - tests run in the absence of light). Total bacterial diversity was assessed by 16s DNA pyrosequencing. Microbial activity was greatest and most variable in sites exposed to disturbance (grazing, natural gas extraction). Decoupling the C cycle from the C-fixing cyanobacteria may induce more diverse C uptake pathways associated with a more diverse microbial population. Similarities in taxonomic diversity and C substrate utilization patterns show that, for arid lands, any degradation-enhanced heterogeneity in soil’s biotic and abiotic parameters may drive changes in soils towards higher functional diversity to adapt to the disturbance

Journals\u27 Policies on Compliance with the NIH Public Access Policy

This resource provides information about select journals\u27 policies related to the NIH Public Access Policy. Many of these journals are based in the social sciences and publish population research articles. Authors who publish in a journal listed below can quickly determine whether the publisher has a policy, who must submit the manuscript and which version to submit to PubMed Central, as well as the embargo period. Journal titles were gathered from the ISI Journals Citation Reports in the subject categories of Demography, Sociology, Economics, and Gerontology.

Introducción a R para el análisis de datos en Ciencias Sociales

Pertenece a la Colección Cartografías: Materiales para la investigación y el aprendizaje. Serie Cuadernos de Investigación Cuantitativa N° 1.Este cuaderno metodológico muestra el uso del entorno R para el análisis de datos a través de una interfaz gráfica de usuario amigable: R-Commander. Por este medio, el investigador que se inicia en el análisis de datos o busca solo una aplicación concreta hallará un software libre, semejante a otros paquetes comerciales. Quienes tengan interés por explorar la flexibilidad de este entorno, podrán ingresar de manera gradual a la programación, en vistas a operaciones más complejas que las provistas por defecto y para personalizar los análisis. El usuario experimentado hallará en R una herramienta muy versátil para aplicar diversas estrategias analíticas y de gran potencialidad gráfica. A fin de ejemplificar la aplicación de los procedimientos, se usan datos de la Encuesta Nacional de Factores de Riesgo 2013, realizada conjuntamente entre el Instituto Nacional de Estadística y Censos (INDEC) y el Ministerio de Salud de la Nación de la República Argentina

El Noviciado de Córdoba de la Provincia Jesuítica del Paraguay : Historia y recuperación arqueológica, 1607-1990

El libro trata la historia de los restos arqueológicos conocidos como la “Cripta Jesuítica del Noviciado Viejo”. Denominación poco afortunada a la vista de las revelaciones históricas que contiene el presente texto. Page aborda los diferentes sitios donde estuvo ubicado el Noviciado de la Provincia Jesuítica del Paraguay, haciendo hincapié en el proyectado por el maestro-arquitecto Johann Kraus, sobre la base de una casa donada por los hermanos jesuitas Ignacio y Francisco Mujica. También evoca los singulares destinos ulteriores que tuvo, donde funcionó la Casa de Ejercicios, Hospital de Bethlemitas… Incluye la vida de los primeros novicios y las no pocas penurias de los jóvenes exiliados en 1767. El tiempo, la memoria colectiva y la intervención del hombre, hicieron desaparecer el edificio del siglo XVIII. Después de mucho tiempo y como un hecho casual, parte del mismo fue redescubierto debajo de la avenida Colón, siendo oportunamente recuperado en 1990

A identidade política do MAS-IPSP na Bolívia.: Tradições, demandas e antagonismos

The aim of this paper is to analyze the MAS-IPSP as a political identity which appeared resisting neoliberalism and became into a successful electoral alternative. The MAS-IPSP won the general elections in Bolivia, in December 2005 and in December 2009. Our propose gives important keys to understand the recent Bolivian political process which shows new articulations between society and politics.En este artículo se pretende analizar al MAS-IPSP en tanto identidad política que emergió en resistencia a la férrea aplicación de políticas neoliberales en Bolivia y se consolidó como una alternativa popular que triunfó en las elecciones nacionales de diciembre de 2005 y de diciembre de 2009. El análisis aquí propuesto arroja importantes claves para comprender el proceso boliviano actual, planteando novedosas articulaciones entre “lo social” y “lo político”.Neste artigo, analisa-se ao MAS-IPSP como uma identidade política que emergiu resistindo a aplicação de políticas neoliberais na Bolívia, e se consolidou como uma alternativa eleitoral que conseguiu ganhar as eleições em dezembro de 2005 e, logo, em dezembro de 2009. Nossa proposta oferece dados importantes que ajudam a compreender o atual processo político boliviano, mostrando novas articulações entre o social e o político

Evaluating the relationship between user interaction and financial visual analysis

It has been widely accepted that interactive visualization techniques enable users to more effectively form hypotheses and identify areas for more detailed investigation. There have been numerous empirical user studies testing the effectiveness of specific visual analytical tools. However, there has been limited effort in connecting a user’s interaction with his reasoning for the purpose of extracting the relationship between the two. In this paper, we present an approach for capturing and analyzing user interactions in a financial visual analytical tool and describe an exploratory user study that examines these interaction strategies. To achieve this goal, we created two visual tools to analyze raw interaction data captured during the user session. The results of this study demonstrate one possible strategy for understanding the relationship between interaction and reasoning both operationally and strategically.
