William Layton en España

This year 2015 marks the 55th anniversary of the establishment in Spain of the first theatre academy whose methodological principles for actors were based on the Stanislavski system —although transformed by the perspective of the Method, developed in America by the Group Theatre during the 1930s and then implanted in some famous schools such as the Actor’s Studio—. It was in October 1960 when the American actor, teacher and director William Layton (1913-1995) opened the Teatro Estudio de Madrid (TEM). By then, he had already been living in Spain for two years. In that adventure Layton was accompanied by the Spanish Miguel Narros (a stage director) and the American Elizabeth H. Buckley. This private academy began its activity by offering the Method, a discipline that Layton had learned in his country with Sandford Meisner; one member of the Group Theatre along with Lee Strasberg, Stella Adler, Harold Clurmann or Elia Kazan. Thanks to the TEM, concepts till then completely unknown in Spanish academic venues for actors such as organicity, truth, mood, sensory memory, etc., started being implemented in the theatrical interpretation. Firstly, in exercises of improvisation; secondly, in scenes and characters; and finally, after a time of performing, those concepts were tested in the scenarios, by display to the public, which is the biggest challenge for any actor, author or director. That way, a singular model of interpretation, a naturalistic type, which have prevailed in the West over other ways of interpreting, came to Spain. A system (which could be defined as organic interpretation) that had been systematized by the Russian Konstantin Stanislavski in the early twentieth century and rapidly was exported abroad by some of his first students: Richard Boleslavsky, Maria Ouspenskaya, Michael Chekhov, Pietro Scharoff, P. Pauloff... Its popularity in the USA increased mainly due to the Actor’s Studio and also thanks to professor Lee Strasberg, through the famous Method working. While in 1960 Layton founded in Madrid the TEM, together with Narros and Buckley, the Brechtian technique was arriving to Barcelona. In that city, Ricard Salvat —who had trained in Germany— and Maria Aurélia Capmany opened the School of Dramatic Art Adrià Gual (EADAG). From Catalonia and over the years, this center will project the first formulas about “distancing”. That way, after decades of delay, that same year 1960 landed in Spain two key trends that shaped and influenced the development of Western theatrical art in the first half of the twentieth century. SYNTHESIS: The knowledge and deep analysis of William Layton’s work as acting teacher in Spain will allow us to get closer to a major figure in the history of theater education in our country. Our main goal is to demonstrate that he was responsible for breaking the isolation that, from secular times, suffered the training of actors in Spain. Layton not only did achieve that, but did it consistently, without interruption. Also, by analyzing his work as stage manager, we will discover how this methodology was implemented in two aspects regarding the theatrical play: in the actor himself and in the dramatic text...

Experimental study of Australian sugarcane bagasse pulp permeability

In this experimental study the permeability of Australian bagasse chemical pulps obtained from different bagasse fractions were measured in a simple permeability cell and the results compared to one another as well as to eucalypt, Argentinean bagasse and pine pulps. The pulps were characterised in terms of the permeability parameters, the specific surface area, Sv, and the swelling factor, α. It was found that the bagasse fraction used affects these parameters. Fractionation of whole bagasse prior to pulping produced pulps that have permeability properties that compare favourably with eucalypt pulp. The values of Sv and α for bagasse pulp also depend on whether a constant or a variable Kozeny factor is used.

The effect of flocculants on the filtration of bagasse pulp pads

This study examined the effect of flocculants on the filtration parameters of bagasse pulp. In the first phase, flocculants were effective for improving the fiber retention of three different bagasse pulp slurries, based on flocculant system studies using a dynamic drainage jar. In the second phase, pulp pads were formed using these flocculants and the steady-state permeability and compressibility parameters were measured. The results showed that the flocculant system that was effective for a pulp slurry was entirely ineffective in improving pulp pad permeability or compressibility during the second experimental phase for two of the bagasse pulp samples.

Sensitivity of organic matter decomposition to warming varies with its quality

The relationship between organic matter (OM) lability and temperature sensitivity is disputed, with recent observations suggesting that responses of relatively more resistant OM to increased temperature could be greater than, equivalent to, or less than responses of relatively more labile OM. This lack of clear understanding limits the ability to forecast carbon (C) cycle responses to temperature changes. Here, we derive a novel approach (denoted Q(10-q)) that accounts for changes in OM quality during decomposition and use it to analyze data from three independent sources. Results from new laboratory soil incubations (labile Q(10-q)=2.1 +/- 0.2; more resistant Q(10-q)=3.8 +/- 0.3) and reanalysis of data from other soil incubations reported in the literature (labile Q(10-q)=2.3; more resistant Q(10-q)=3.3) demonstrate that temperature sensitivity of soil OM decomposition increases with decreasing soil OM lability. Analysis of data from a cross-site, field litter bag decomposition study (labile Q(10-q)=3.3 +/- 0.2; resistant Q(10-q)=4.9 +/- 0.2) shows that litter OM follows the same pattern, with greater temperature sensitivity for more resistant litter OM. Furthermore, the initial response of cultivated soils, presumably containing less labile soil OM (Q(10-q)=2.4 +/- 0.3) was greater than that for undisturbed grassland soils (Q(10-q)=1.7 +/- 0.1). Soil C losses estimated using this approach will differ from previous estimates as a function of the magnitude of the temperature increase and the proportion of whole soil OM comprised of compounds sensitive to temperature over that temperature range. It is likely that increased temperature has already prompted release of significant amounts of C to the atmosphere as CO2. Our results indicate that future losses of litter and soil C may be even greater than previously supposed.

Don't sell social science short

The News of the Week article that reports on Senator Kay Bailey Hutchison (R-TX) questioning the need to fund social science research at the National Science Foundation is alarming and shortsighted ("Senate panel chair asks why NSF funds social sciences," 12 May, p. 829). Social science research is at the fundamental core of basic research and has much to contribute to the economic viability of the United States. Twenty years of direct and jointly funded social and ecosystem science research at Colorado State University's Natural Resource Ecology Laboratory has produced deep insights into environmental and societal impacts of political upheaval, land use, and climate change in parts of Africa, Asia, and the Americas. Beyond greatly advancing our understanding of the coupled human-environmental system, the partnership of social and ecosystem science has brought scientists and decision-makers together to begin to develop solutions to difficult problems.

Nitrogen pools and fluxes in grassland soils sequestering carbon

Carbon sequestration in agricultural, forest, and grassland soils has been promoted as a means by which substantial amounts of CO2 may be removed from the atmosphere, but few studies have evaluated the associated impacts on changes in soil N or net global warming potential (GWP). The purpose of this research was to ( 1) review the literature to examine how changes in grassland management that affect soil C also impact soil N, ( 2) assess the impact of different types of grassland management on changes in soil N and rates of change, and (3) evaluate changes in N2O fluxes from differently managed grassland ecosystems to assess net impacts on GWP. Soil C and N stocks either both increased or both decreased for most studies. Soil C and N sequestration were tightly linked, resulting in little change in C: N ratios with changes in management. Within grazing treatments N2O made a minor contribution to GWP (0.1-4%), but increases in N2O fluxes offset significant portions of C sequestration gains due to fertilization (10-125%) and conversion (average = 27%). Results from this work demonstrate that even when improved management practices result in considerable rates of C and N sequestration, changes in N2O fluxes can offset a substantial portion of gains by C sequestration. Even for cases in which C sequestration rates are not entirely offset by increases in N2O fluxes, small increases in N2O fluxes can substantially reduce C sequestration benefits. Conversely, reduction of N2O fluxes in grassland soils brought about by changes in management represents an opportunity to reduce the contribution of grasslands to net greenhouse gas forcing.

Constraints of nutrient availability on primary production in two alpine tundra communities

A nutrient amendment experiment was conducted for two growing seasons in two alpine tundra communities to test the hypotheses that: (1) primary production is limited by nutrient availability, and (2) physiological and developmental constraints act to limit the responses of plants from a nutrient-poor community more than plants from a more nutrient-rich community to increases in nutrient availability. Experimental treatments consisted of N, P, and N+P amendments applied to plots in two physiognomically similar communities, dry and wet meadows. Extractable N and P from soils in nonfertilized control plots indicated that the wet meadow had higher N and P availability. Photosynthetic, nutrient uptake, and growth responses of the dominants in the two communities showed little difference in the relative capacity of these plants to respond to the nutrient additions. Aboveground production responses of the communities to the treatments indicated N availability was limiting to production in the dry meadow community while N and P availability colimited production in the wet meadow community. There was a greater production response to the N and N+P amendments in the dry meadow relative to the wet meadow, despite equivalent functional responses of the dominant species of both communities. The greater production response in the dry meadow was in part related to changes in community structure, with an increase in the proportion of graminoid and forb biomass, and a decrease in the proportion of community biomass made up by the dominant sedge Kobresia myosuroides. Species richness increased significantly in response to the N+P treatment in the dry meadow. Graminoid biomass increased significantly in the wet meadow N and N+P plots, while forb biomass decreased significantly, suggesting a competitive interaction for light. Thus, the difference in community response to nutrient amendments was not the result of functional changes at the leaf level of the dominant species, but rather was related to changes in community structure in the dry meadow, and to a shift from a nutrient to a light limitation of production in the wet meadow.

Pressure filtration of Australian bagasse pulp

A one-dimensional pressure filtration model that can be used to predict the behaviour of bagasse pulp has been developed and verified in this study.The dynamic filtration model uses steady state compressibility parameters determined experimentally by uniaxial loading. The compressibility parameters M and N for depithed bagasse pulp were determined to be in the ranges 3000–8000kPa and 2.5–3.0 units, respectively. The model also incorporates experimentally determined steady state permeability data from separate experiments to predict the pulp concentration and fibre pressure throughout a pulp mat during dynamic filtration. Under steady state conditions, a variable Kozeny factor required different values for the permeability parameters when compared to a constant Kozeny factor. The specific surface area was 25–30% lower and the swelling factor was 20–25% higher when a variable Kozeny factor was used. Excellent agreement between experimental data and the dynamic filtration model was achieved when a variable Kozeny factor was used.

Review of Dr. Richard Shapcott's International Ethics : A Critical Introduction. 2010. London: Polity Press. ISBN-13: 978-0-7456-3142-4.

This work by Richard Shapcott is, as the title provides, an introduction to international ethics. By taking a quick glance at the table of contents (see Figure 1) we see that he has systematically divided this particular discourse into its normative areas of concern (in other words its major areas of argument or research). When reading, we also see that a great deal of work has gone into the publication because the narrative is flowing, the arguments continuous, and because the tone of the work maintained its critical position throughout.
