The long-term impact of initial resource availability and seed bank on woody vegetation during early succession on the New Jersey Piedmont
No full textThis study revisited old field succession plots established in 1989 at Hutcheson Memorial Forest in Somerset County, New Jersey, to look at the impact of initial resource availability and seed bank on old field succession. A combination of two different types of treatments were used: an abiotic treatment to alter available resources, and a seed treatment to change the starting seed bank. The abiotic treatments used were a light reduction, mulch application, and an elemental sulfur application to reduce nutrient availability. Seed treatments were additions of species characteristic of early, mid, or late succession. Soils from the plots was analyzed for pH and nutrient availability to determine whether any residual effects of the initial treatments still existed after 19 years. The species, density, and diameter at breast height (DBH) of all woody vegetation >2m tall was taken, and the density and species of seedlings <50cm in height were also taken. Due to loss of data through destruction of 18 out of 48 original plots, Bayesian analysis in WinBUGS was used as the primary form of statistical analysis. Unpublished data from 1997 was used in order to determine how the Bayesian analysis results correlated with the two-way ANOVA used in past analysis of the site, and to ensure that results using full and partial datasets were similar. Relative importance values for species present on the plot were also calculated. Sulfur treatments had a significant impact on the soil, resulting in lower pH and differences in nutrient availability. No difference in soil organic matter was found. The mature woody vegetation was shown to have lasting differences associated with initial abiotic treatments. Light reduction yielded smaller trees at lower density; mulch treatments had larger trees at high density, and sulfur-treated plots had large trees at very low densities. Little difference was found associated with the seed treatments. No differences were found in the seedling populations. Juniperus virginiana was the dominant species in most plots, with the exception of sulfur-treated plots. Comparison of 1997 data and 2008 data suggests that differences in woody species composition are determined by differences in seedling survival.M.S.Includes bibliographical referencesby Alexandra Emily Chen Fowle

From role-playing to role-taking: Interpreter role(s) in healthcare
No full textAgainst the background of the current literature on (interpreter-mediated) doctor-patient interactions, and of a study of real interpreting situations recorded in Italy and Belgium, this paper presents an analysis of medical role-plays recorded in one of the major Italian universities training interpreters. The paper sets out to check to what extent participants fulfill the “ideal template” of dialogue interpreting (AIBIA turn pattern), locating departures and raising questions like: who initiates them and how do the interlocutors position themselves? Are there any differences with departures in real data? Is role-playing a good way of introducing students to role-taking in healthcare? Combining notions from Conversation Analysis and Interpreting Studies, this paper outlines some of what works and what is missing in role-plays as a training technique
Stages for the More Sustainable Farm
No full textCurrently, agricultural farm units are faced with a double and most times contradictory challenge, in order to be successful: on the one hand the invested capital has to be profitable and the economic performance has to be maximised. On the other hand, given the socio-environmental situation, it is necessary to preserve and to protect the environment and natural resources. Given the potential conflict of the two aims, since the satisfaction of one implies the underperformance of the other (and vice versa), the question then is: which is the solution to choose? We intend, in this work, to formulate a farm plan with the purpose of reconciling the criteria of environmental sustainability with that of economic competitiveness. For this achievement we proceed to the comparative study of sustainability of different groups of farms identified in the study area (first evaluation cycle) through MESMIS (“Marco para la Evaluación de Sistemas de Manejo de Recursos Naturales Mediante Indicadores de Sustentabilidad” - Framework for Evaluation of Natural-Resource Systems Handling through Sustainability Indicators) methodology, that allowed to select the more sustainable group of farms. Based on the found potentialities and weakness on these production systems, we stepped to the planning of a production unit of bovine meat, which obeys simultaneously to economic and environmental objectives, using Multicriteria Decision. We finished the work with the sustainability evaluation between groups of farms identified previously and the planned farms (second evaluation cycle), based, again, in the MESMIS methodology, to confirm (or not) the greatest sustainability of the last ones. Analyses of the results allow us to confirm the greatest relative sustainability of the planned farm, for the diverse traced scenarios.Decision taking, planning, sustainability, Environmental Economics and Policy, Farm Management,
Reescrita de si pelo outro: identidade portuguesa e paródia em Deus-dará, de Alexandra Lucas Coelho / Rewriting oneself through the other: Portuguese identity and parody in Deus-dará, by Alexandra Lucas Coelho
No full textResumo: O artigo aponta o modo como o romance Deus-dará de Alexandra Lucas Coelho, escritora portuguesa contemporânea, pode ser compreendido como um exercício de renegociação da identidade portuguesa em relação a questões referentes à colonização no Brasil. Mais do que isso, problematiza-se como, por meio da estratégia da paródia no texto ficcional, a autora consegue expressar uma necessidade e possibilidade de se redefinir pelo outro em um movimento contrário ao do discurso colonial – o que também ocorre em suas entrevistas e em suas narrativas de viagens, tais como em Vai, Brasil e Cinco Voltas na Bahia e um beijo para Caetano Veloso. Palavras-chave: identidade portuguesa; paródia; pós-modernismo; escrita portuguesa contemporânea; Alexandra Lucas Coelho. Abstract: The article observes how the novel Deus-dará, by Alexandra Lucas Coelho, a Portuguese contemporary writer consists in an exercise of renegotiation for the Portuguese identity in relation to issues that refer to the colonization process in Brazil. Moreover, this text seeks to show how parody as a fictional literary strategy helps the author in expressing a necessity and a possibility of redefining oneself through the other, in a direction that goes in the opposite way of the colonial speech. This necessity and this possibility also appear in the author’s interviews and travel books, such as Vai, Brasil and Cinco Voltas na Bahia e um beijo para Caetano Veloso, which will also be mentioned in this article.Keywords: Portuguese identity; parody; post-modernism; Portuguese contemporary writing; Alexandra Lucas Coelho

TRAGIC NOISE AND RHETORICAL FRIGIDITY IN LYCOPHRON'S ALEXANDRA
No full textAbstract This paper seeks to shed fresh light on the aesthetic and stylistic affiliations of Lycophron's Alexandra , approaching the poem from two distinct but complementary angles. First, it explores what can be gained by reading Lycophron's poem against the backdrop of Callimachus’ poetry. It contends that the Alexandra presents a radical and polemical departure from the Alexandrian's poetic programme, pointedly appropriating key Callimachean images while also countering Callimachus’ apparent dismissal of the ‘noisy’ tragic genre. Previous scholarship has noted links between the openings of the Aetia and of the Alexandra , but this article demonstrates that this relationship is only one part of a larger aesthetic divide between the two poets: by embracing the raucous acoustics of tragedy, Lycophron's poem offers a self-conscious and agonistic departure from Callimachus’ aesthetic preferences. Second, this article considers another way of conceiving the aesthetics of the poem beyond a Callimachean frame, highlighting how Lycophron pointedly engages with and evokes earlier Aristotelian literary criticism concerning the ‘frigid’ style: the Alexandra constructs its own independent literary history centred around the alleged name of its author, ‘Lycophron’. The article proposes that this traditional attribution is best understood as a pen name that signposts the poem's stylistic affiliations, aligning it not so much with the Ptolemaic playwright Lycophron of Chalcis but rather with Lycophron the sophist and a larger rhetorical tradition of stylistic frigidity. Ultimately, through these two approaches, the article highlights further aspects of the Alexandra 's aesthetic diversity
Strategic cognition in paranoia: the use of thought control strategies in a non-clinical population
No full textBackground: Recent work in the area of cognition and emotion has focused on the process as well as the content of thought. Metacognitive approaches have included studies of people's relationship with internal experience (cf. Teasdale and Barnard, 1993), and the overarching beliefs that guide allocation of internal resources to manage distress (cf. Wells, 2000). At the same time, cognitive models of psychosis have emphasized the clinical value of a multidimensional understanding of paranoia (Chadwick, 2006; Freeman and Garety, 2004b). Method: This study examined paranoia in a non-clinical group, specifically (i) the relationship between a single measure of trait paranoia and dimensions of paranoid thought frequency, belief conviction and distress, and (ii) the metacognitive strategies that people use. It was predicted that trait paranoia would be associated with (i) dimensions of thought frequency, belief conviction and distress, and (ii) the internal strategies of “punishment” and “worry.” Results: Regression analyses showed that trait paranoia uniquely predicted frequency, conviction and distress associated with paranoid thoughts. Trait paranoia accounted for the use of “reappraisal”, whereas “punishment” and “worry” were accounted for by anxiety. Conclusions: The implications for clinical work and further research are discussed
Fungal community assessment in Canadian arctic soils from Alexandra Fiord, Ellesmere Island, Nunavut.
No full textFungal communities in arctic soils tend to be less diverse compared to the communities in temperate forest soils due to the harsher environmental conditions. Even in a single arctic site such as Alexandra Fiord, considered a terrestrial arctic oasis, fungal diversity is expected to be lower compared to soils in less extreme environments. We hypothesized that variations in environmental factors would play an important role in determining fungal community structure, as the Alexandra Fiord soils exhibits considerable environmental variation in a small geographic area. To test this hypothesis, we collected soil samples from three sites across the landscape and performed length-heterogeneity polymerase chain reaction (LH-PCR) analyses using ITS3 and NLB4 primers, which have been used successfully to characterize complex communities. Our results showed that there were large relative differences in fungal community structure between the sites. At the Alexandra Fiord Highland Dolomitic site diversity was low with genotypes relatively evenly distributed, whereas Alexandra Fiord Highland Granitic and Alexandra Fiord Lowland sites had higher diversity and a less even distribution of genotypes with a few occurring at a high frequency and many rare species. Among environmental variables, soil moisture, temperature, DOC, DON, C:N ratio and soil pH were significant influential factors in determining fungal community structure. Among these environmental factors, pH showed the strongest correlation with the fungal community data. --P. ii.The original print copy of this thesis may be available here: http://wizard.unbc.ca/record=b174111
