Full textThis thesis is the result of reflections on 27 years of work as a psychologist and psychoanalyst, and makes special reference to the work that since late 1997, has been developed in the Studio Acaia, NGOs that receive the school counter-part in various workshops, children, adolescents and families from two slums and a low-income housing development surrounding the marketing year of warehouses and general warehouses of São Paulo (Ceagesp). These are issues related to the potential of psychoanalysis, in addition to the office of clinical and continues the ideas presented in the master\'s thesis \"Extensive Clinic: psychoanalysis where it is needed.\" In the Studio Acaia, the activities in forms of studios/workshops, the way we established working groups and the means of intervention of educators team generated a field of knowledge that, for some years, has been perceived as an important model exchange and discussion and encouraged me to investigate it as a living organism and propellant these strategies. As part of the growing slums of large cities, the idea of taking the Acaia a thesis on it is anchored, from my point of view, the interest in thinking about it as a possible matrix of projects, and to reflect on the management of Acaia with psychoanalytic character, explain how psychoanalysis can make important contributions to emerging contemporary issues. This research is to sense the possibility of a work that expresses a way of doing research at the university with operating return, ensuring production of knowledge in line with the concrete demands of the community

Full textLa scelta della regione del Peloponneso come oggetto di questo studio nasce dalla possibilità, offerta da tale contesto agli studiosi contemporanei, di potersi confrontare con un territorio ricco di tracce materiali, testimonianze storiche e monumentali di un passato nel quale essa è stata al centro del mondo antico. La proposta di tentare una ricostruzione storica dei paesaggi attraverso le fonti documentarie e la Cartografia storica si inserisce in un filone europeo di studi, che pone le basi nel metodo regressivo di matrice storica, e nell’individuazione ed interpretazione di tracce quali segni residuali del passato nei paesaggi contemporanei. I paesaggi sono elementi pluristatificati dove “le opere durature dell’uomo ovvero le strutture e le infrastrutture necessarie alla sua vita, al suo agire economico, culturale e spirituale, si sovrappongono al substrato naturale e si inseriscono in una eredità storica in via di progressivo arricchimento”. Il “paesaggio storico” è il risultato delle mutate culture, dell’approccio diverso che i vari gruppi umani hanno con l’ambiente che li ospita, e, fattore da non sottovalutare, delle caratteristiche geomorfologiche che hanno determinato l’evoluzione dei luoghi, come le tipologie di occupazione e di sfruttamento. Gli aspetti fisici di un territorio, come i fiumi, i monti, le vallate, determinano la forma degli spazi e rappresentano gli elementi di lunga durata su cui si impostano i paesaggi, che a loro volta vivono e mutano a seconda delle sollecitazioni dell’uomo. Il metodo archeologico per la ricostruzione del paesaggio storico, come notato già da Rizakis nel 1992, è stato elemento di discussione fra i sostenitori di un’archeologia estensiva, che procede all’esplorazione di vaste zone e quanti sono a favore di un approccio intensivo ed esaustivo, che predilige campioni ridotti con il risultato di una maggiore completezza dell’indagine. Il primo approccio traccia su una buona base di dati le linee generali della storia del popolamento, ma dà risposte deboli sui cambiamenti e sulle problematiche relative alla ... [a cura dell'autore]

Umas das principais razões que presidiram à escolha do Mestrado três semestres atrás foi a falta de edições de teatro com que fomos confrontados no curso. Ou não existia a peça traduzida, ou a edição tinha erros, ou era velha, ilegível, com letra pequena, com espaços indistintos, ou a linguagem precisava de ser actualizada. E poucas vezes se ouve falar de editoras que apoiem a edição teatral, pelo menos até há três ou quatro anos atrás, porque o jogo envolve dinheiro, principalmente, e uma peça tem4 um número diminuto de leitores e interessados. A Livraria privilegia o texto teatral e em obras sobre a arte do espectáculo, preenchendo o vácuo da edição teatral, facilitando a sua aquisição por aqueles que precisam das obras e por aqueles que simplesmente as desejam apreciar, estudar e compreender, dividindo-as em duas colecções, a Colecção TNMII, divulgando edições das peças levadas ao palco e a Colecção Estudos para aqueles que estudam o teatro na sua teoria e prática, editando-as em colaboração com a Quimera Editora5 e, mais recentemente, a Bicho do Mato.

Full textENGLISH ABSTRACT: This thesis investigates the invasiveness and current status of two Acacia species recently identified as invaders in South Africa in order to determine the feasibility of their eradication. Australian acacias are among South Africa’s worst invasive species and many have had widespread damaging impacts on native ecosystems. In addition, several Acacia species still exist as small isolated populations in the country and have been targeted for eradication in order to prevent potential widespread impacts. This work assesses Acacia implexa (Chapter 2) and Acacia stricta (Chapter 3) as potential eradication targets by quantifying the extent of their invasion in South Africa, assessing the risk they pose to the country and evaluating the feasibility of their eradication based on estimated costs of clearing. Results of formal risk assessments show that both A. implexa and A. stricta should be considered high risk species, and bioclimatic model predictions indicate that both species have large potential ranges in South Africa. Detailed population surveys found that A. implexa and A. stricta each occur at several distinct localities all in the Western Cape Province. Acacia implexa populations were found at three sites (Tokai, Wolseley and Stellenbosch) where they have densified by means of vegetative suckering allowing A. implexa to outcompete native vegetation. No evidence of large seed banks of A. implexa were found, however vigorous resprouting following damage makes the control of A. implexa difficult. Acacia stricta was found at nine localities all in the Knysna area of the Garden Route, where populations are spreading along disturbed roadsides in plantations. Acacia stricta produces large amounts of seeds and can accumulate large seed banks. Seed spread is most likely due to large-scale soil movement by road maintenance vehicles which can easily lead to the establishment of new populations. We therefore used a predictive risk mapping approach based on the association of A. stricta to roadsides and disturbed plantations to enable effective searching to detect all infestations of A. stricta. Based on the high risk of both species and the limited range sizes of the currently known populations, we recommend that A. implexa and A. stricta remain targets for eradication. Management strategies proposed for these species (Chapter 4) include clearing on an annual (in the case of A. stricta) or biannual (for A. implexa) basis to prevent seed production, and targeted awareness campaigns at a national scale to determine whether our current knowledge of the extents of A. implexa and A. stricta are accurate. This work has shown that detailed assessments of species at intermediate stages of invasion is an important initial step in an eradication attempt, and better understanding of species specific invasion characteristics can help to improve management and potentially increase the probability of success of eradication.
AFRIKAANSE OPSOMMING: Hierdie tesis ondersoek die invasieve en die huidige status van twee Acacia spesies onlangs geïdentifiseer as indringers in Suid-Afrika ten einde die lewensvatbaarheid van hul uitwissing om te bepaal. Australiese akasias is onder Suid-Afrika se ergste indringerspesies en baie het wydverspreide skadelike impak op die inheemse ekosisteme. Verder het verskeie Acacia spesies bestaan nog steeds as 'n klein geïsoleerde bevolkings in die land en wat geteiken is vir uitwissing in om moontlike grootskaalse impakte te voorkom. Hierdie werk beoordeel Acacia implexa (Hoofstuk 2) en Acacia stricta (Hoofstuk 3) as 'n moontlike uitwissing teikens deur die kwantifisering van die omvang van hul inval in Suid-Afrika, die beoordeling van die risiko wat hulle inhou vir die land en die evaluering van die haalbaarheid van hul uitwissing op grond van beraamde koste van die wiele ry. Resultate van formele risikobepalings toon dat beide die A. implexa en A. stricta moet oorweeg word om 'n hoë risiko spesies, en bioclimatic model voorspellings dui daarop dat beide spesies het 'n groot potensiaal bereik in Suid-Afrika. Uitgebreide bevolkings opname gevind dat A. implexa en A. stricta elk by verskeie afsonderlike plekke in die Wes-Kaap voorkom. Acacia implexa is op drie plekke (Tokai, Wolseley en Stellenbosch) gevind, waar hulle deur middel van vegetatiewe suier densified en inheemse plantegroei oorwin het. Geen bewyse van groot nageslag banke van A. implexa is gevind, maar in kragtige resprouting volgende skade maak die beheer A. implexa moeilik is. Die Acacia stricta is op nege plekke in die Knysna-omgewing van die Tuinroete, waar die bevolkings verspreiding langs die versteurde paaie in plantasies. Acacia stricta produseer groot hoeveelhede saad en kan versamel groot saadbanke. Saad versprei is waarskynlik te danke aan grootskaalse grond beweging deur die instandhouding van paaie voertuie wat kan lei tot die vestiging van nuwe bevolkings. Ons het dus 'n voorspellende risiko kartering benadering wat gebaseer is op die vereniging van A. stricta aan paaie en versteurde plantasies in staat te stel om doeltreffend te soek alle besmettings van A. stricta op te spoor. Gegrond op die hoë risiko van beide spesies en die beperkte reeks groottes van die bevolking wat tans bekend is, beveel ons aan dat A. implexa en A. stricta bly teikens vir uitwissing. Bestuurstrategieë vir hierdie spesies (Hoofstuk 4) voorgestel word, sluit in die skoonmaak op 'n jaarlikse (in die geval van A. stricta) of die halfjaarlikse (vir A. implexa) basis van die saad produksie, en geteikende bewusmakingsveldtogte om te voorkom dat 'n nasionale skaal om te bepaal of ons huidige kennis van die omvang van A. implexa en A. stricta akkuraat is. Hierdie werk het getoon dat uitgebreide aanslae van spesies op intermediêre fases van die inval is 'n belangrike eerste stap in 'n poging van die uitwissing, en 'n beter begrip van spesies spesifieke inval eienskappe kan jou help om te verbeter en potensieel verhoog die waarskynlikheid van sukses van die uitroeiing nie.

Full textWood used for pulp production may be divided in two major groups regarding fiber function: hardwood (short fiber) and softwood (long fibers). Hardwood species are mainly designated to writing and printing papers. Hardwood principal species used for production of short fiber pulp in other countries are Eucalyptus globulus (Iberian Peninsula and Chile), Eucalyptus nitens (Chile), Populus tremuloides (Canada), Acacia mangium and Acacia crassicarpa (Indonesia). This study aimed to evaluate and compare the performance of the main woods used worldwide for short fiber pulp production regarding wood quality parameters such as chemical composition, basic density and wood anatomical properties, in order to provide strategic information for national pulp and paper industry, aiming the knowledge and competitiveness of these woods at worldwide market. To accomplish this study, 5 trees from each species were collected and wood chips were manually cut. In relation to the wood, basic density, chemical composition and fiber lengths were determined. The results were statistically analyzed and the different species were compared regarding wood quality.

Full textThe aim of this study was to improve the knowledge on seed-coat dormancy and germination skills of Acacia, seeking to clarify key aspects relating to the efficiency of its expansion through seed propagation. The species, Acacia longifolia (provenance: Sintra) and A. dealbata (provenances: Fundão and Cabrum river valley), are considered two of the most invasive of its genus in Portugal. For both species two seed propagation tests were performed: one for pre-germination treatment and another for germination in nursery environment. In these trials, we determined the weight of seeds, the germination rate and the vigor index; hot water (90° C followed by 24 hour immersion) was used to break the seed-coat dormancy. In the experiment performed in the nursery the two species were also compared for the rate of mortality, and for vitality through the determination of chlorophyll fluorescence. The results indicated that Acacia longifolia has a higher fitness than A. dealbata to seed propagation. This capability was confirmed by a potential germination in chamber significantly higher than that of A. dealbata, by a higher germination rate in nursery and higher vitality of seedlings produced, measured by a post-germinative mortality rate significantly lower.

Full textVariability in fire, herbivory, and climate facilitate the coexistence of trees and grasses in savannas and impact upon savanna structure, which also varies substantially both spatially and temporally. These features can shape savannas at an ecosystem and even at a global scale, but mechanisms for the effects of fire, herbivory, and climate variability on tree cover are often demographic at the tree population level. Sapling growth in particular has repeatedly been shown to be the limiting step, or 'bottleneck', in the establishment of trees in savannas. I set out to investigate how spatial and temporal variability in fire, herbivory, and climate shape population dynamics of a suite of common African savanna trees, the Acacia, in a landscape context. I carried out my field work in Hluhluwe iMfolozi Park in K waZulu Natal, South Africa, during 2006 and 2007. Fire, herbivory, and the grass layer were primary determinants of distributions and co-occurrence of Acacia species.

Full textENGLISH ABSTRACT: Australian Acacia species are an important group of invaders and are known to form dense monospecific cultures in invaded habitats. Despite the ecological and economic importance of invasive acacias, little is known about their invasive biology both from an ecological and evolutionary perspective. Molecular genetic methods have increasingly become important in identifying source populations for invasive species and determining the population genetic structure of these populations. This thesis applied molecular tools to understand the invasion ecology of Acacia pycnantha and its rhizobial symbionts as a model system of Australian Acacia introductions. Specific objectives were to: reconstruct the molecular phylogeny of invasive and native populations of populations of Acacia pycnantha and identify the native provenance of A. pycnantha; identify microsatellite markers for Acacia pycnantha and other invasive Australian acacias based on transferring microsatellite markers developed for A. mangium, A. saligna, Paraserianthes lophantha and universal chloroplast microsatellites developed from tobacco; assess the introduction dynamics of Acacia pycnantha in South Africa and identify the source populations in the species’ native range ; and determine which nitrogen fixing symbionts nodulate A. pycnantha and determine whether A. pycnantha brought its symbionts along from its native range or acquired them in the invasive range. Nuclear and chloroplast DNA sequence data were used to reconstruct phylogeographic relationships between native and invasive A. pycnantha populations. The chloroplast phylogeny showed that Australian populations of A. pycnantha are geographically structured into two previously informally recognized lineages (representing wetland and dry land forms). Habitat fragmentation is probably the result of cycles of aridity and abundant rainfall during the Pleistocene0. The invasive population in Portugal was found to be the wetland form while South African populations were found to be predominantly wetland form although some dryland forms were identified. Thirty microsatellites out of the forty nine tested microsatellites successfully amplified across all species tested (A. implexa, A. longifolia, A. melanoxylon, A. pycnantha and A. podalyriifolia). High Transfer rates varied between 85% for microsatellites developed for A. mangium to 50% for those developed in A. saligna. Although transfer rates were high only twelve microsatellites (24%) out of the fifty tested were polymorphic while the chloroplast microsatellites showed no polymorphism. The low level of polymorphic loci calls for development of more microsatellites in this genus especially for species that have high commodity value. Nuclear microsatellites revealed three genetic groupings with substantial admixture in the native range (1. wetland Victoria and South Australia populations; 2. dryland Victoria and Flinders Range population; and 3. New South Wales). Admixture in the native range may have occurred as a result of reforestation exercises. Acacia pycnantha has been widely used in rea forestation projects in Australia because of its fast growth rate and ease of germination. Admixed populations were most - likely introduced to South Africa thus establishment of A. pycnantha may have been facilitated by already admixed propagules in the invasive range. Extensive admixture in the native range made it difficult to identify source populations of invasive A. pycnantha found in South Africa. The rhizobial symbionts of A. pycnantha were identified, showing that this species utilizes a wider suite of symbionts in its invasive range than its native range and there is support for both the co-introduction and host jumping hypotheses.
