Spatial and temporal variability of vegetation status in Paraíba, Northeastern Brazil
No full textDesertification is a serious problem in northeastern Brazil and the land degradation process needs to be understood in order to develop a sustainable land use. This study considers the aspect of spatial and temporal vegetation variability in the state of Paraíba. A ten year time period of the enhanced vegetation index (EVI) from MODIS satellite data with a high temporal resolution (16 days) and medium spatial resolution (250 m) was analyzed. In addition, a ten year EVI time series with monthly time intervals and 1 km spatial resolution was correlated with a precipitation time series. Vegetation in Paraíba is characterized by a high variability of greenness on the intra-annual and inter-annual level as well as on the spatial dimension. The highest correlation between EVI and precipitation is achieved for a time lag of 1 month (regional R= 0.64)
Assessing vegetation variability and trends in north-eastern Brazil using AVHRR and MODIS NDVI time series
No full textDesertification is a challenge in north-eastern Brazil (NEB) that needs to be understood todevelop sustainable land-use strategies. This study analyses regional vegetation dynamics in NEB and the compatibility of two NDVI data sets to support future desertification assessment studies in the semi-arid Caatinga biome. Vegetation variability and trends in NEB are analysed for 1982-2006, based on monthly AVHRR (GIMMS) NDVI data. The GIMMS data are compared with MODIS NDVI for the overlapping period 2001-2006. Existing statistical methods are applied and existing NDVI analyses in NEB expanded in respect to vegetation trend analysis and data set comparison
Vegetation Greenness in Northeastern Brazil and Its Relation to ENSO Warm Events
No full textThe spatio-temporal variability of trends in vegetation greenness in dryland areas is a well-documented phenomenon in remote sensing studies at global to regional scales. The underlying causes differ, however, and are often not well understood. Here, we analyzed the trends in vegetation greenness for a semi-arid area in northeastern Brazil (NEB) and examined the relationships between those dynamics and climate anomalies, namely the El Nino Southern Oscillation (ENSO) for the period 1982 to 2010, based on annual Normalized Difference Vegetation Index (NDVI) values from the latest version of the Global Inventory Modeling and Mapping Studies (GIMMS) NDVI dataset (NDVI3g) dataset. Against the ample assumption of ecological and socio-economic research, the results of our inter-annual trend analysis of NDVI and precipitation indicate large areas of significant greening in the observation period. The spatial extent and strength of greening is a function of the prevalent land-cover type or biome in the study area. The regression analysis of ENSO indicators and NDVI anomalies reveals a close relation of ENSO warm events and periods of reduced vegetation greenness, with a temporal lag of 12 months. The spatial patterns of this relation vary in space and time. Thus, not every ENSO warm event is reflected in negative NDVI anomalies. Xeric shrublands (Caatinga) are more sensitive to ENSO teleconnections than other biomes in the study area
Anne as Pagan, Anne as Queer
No full text‘Anne as Pagan, Anne as Queer’ is a critical and creative answer to the question: How do we construct Anne Shirley, and what does she mean to us? This creative research submission is a work of fanfiction, specifically a mash up based on Anne of the Island, L.M.M. Montgomery’s sequel to Anne of Green Gables. In this short work of fiction (under 4 thousand words) Anne is revealed as a changeling, one of the Faerie Folk, and also a being not strictly male or female; sometimes neither, sometimes both. The mash up is based on the last two chapters of Anne of the Island, the scenes in which Gilbert Blythe is seriously ill and Anne realises she loves him. This realisation causes Anne, in this version, to reveal to Gilbert that she is both non-human and not a girl, and to use Faerie magic to save Gilbert’s life. Anne’s revelation causes Gilbert a great relief, as he has been keeping a secret also - that he too is queer. The piece has an accompanying research statement and reflection, that reflects on the ways the contributor/author interprets Anne, as a being troubled by gender, and not strictly gender conforming. The much-loved scene from Anne of Green Gables in which Anne realises she is not wanted by the Cuthberts because she is not a boy is inserted into the mash up (as a memory) as this scene is the principal cause for the contributor’s identification with Anne as a gender non-conforming figure who resists gender expectations. Overall, this creative and critical work and reflection queers both Anne as a character and the Anne of the Island novel.Book chapter - work of fiction with a critical reflective essa

A sojourn in Paris 1824-25: sex and sociability in the manuscript writings of Anne Lister (1791-1840)
No full textThis thesis examines the day to day practices that constituted Anne Lister's (1791-1840) sexuality and sociability within the range of her writings, as well as her society. Anne's writings were a detailed account, spanning her lifetime, of her own love and relationships with the 'fairer sex' (Whitbread 1988, 145). Anne's sociality, seen in her correspondence and plain handwritten journal entries, has been explored by Muriel Green in Miss Lister of Shibden Hall and Jill Liddington in Female Fortune and Nature's Domain (Green 1992; Liddington 1998; 2003). As a gentlewoman of adequate means, Anne has garnered some attention from women's historians interested in her agency within an early nineteenth century social and historical context. Anne's sexual identity has been extensively analysed over the past nearly twenty years by lesbian feminists, queer theorists, women's historians and historians of sexuality concerned with the history and development of modern Western female homosexuality and gender. The source for theorising Anne's sexuality has been the edited selections of the crypted journal entries, published by Helena Whitbread in I Know My Own Heart and No Priest but Love (Whitbread 1988; 1992). However, many analyses deal either with the theorisation of Anne's sexuality or her sociality; the theoretical difficulty with reconciling these categories has troubled the analysis of her complex subjectivity. Drawing upon the archival materials, I have used an interdisciplinary feminist approach to analyse the sexual and social processes of Anne's everyday interactions in her writings. Taking the seven month period of the sojourn to Paris in 1824-25, I have focused upon Anne's textual practices within her journal volume and letters during her residence in Paris, her social practices with the other guests at the guesthouse 24 Place Vendome and her sexual practices with her lover, the widow Mrs. Maria Barlow. The journal volumes and correspondence are a valuable historical record of one gentlewoman's engagement with early nineteenth century British culture
