Social entrepreneurship practices and social change In Brazil: a qualitative study in three non-governmental organizations

Social Entrepreneurship (SE) has attracted growing interest from a wide variety of actors over the last 30 years, especially due to a general agreement that it could be an important tool for tackling many of the world’s social ills. In the academic sphere, this growing interest did not translate into a matured field of study. Quite the opposite, a quick look at this literature makes it evident that: SE has been consistently subjected to numerous theoretical discussions and disagreements, especially over the definition of the concept of SE which is often based on a taken-for-granted notion of social change; it has been more systematically investigated in restricted contexts, often leaving aside so called developing/emerging countries like Brazil and especially lacking in-depth qualitative studies; SE literature lags behind SE practices and few studies focus on how SE actually occurs in a daily and bottom-up manner. In order to address such gaps, this thesis examines how social entrepreneurship practices accomplish social change in the context of Brazil. In this investigation I conducted an inductive practice-based, qualitative/ethnographic study in three Non-Governmental Organizations (NGOs) located in different cities in the Brazilian state of São Paulo. Data collection lasted from February 2014 until March 2015 and was mainly done through participant observations and through in-depth unstructured conversations with research participants. Secondary data and documents were also collected whenever available. The participants of this study included a variety of the studied organizations’ stakeholders: two founders, volunteers, employees, donors and beneficiaries. Observation data was kept in fieldnotes, conversations were recorded whenever possible and were later transcribed. Data was analyzed through an iterative thematic analysis. Through this I identified eight recurrent themes in the data: (1) structure; (2) relationship with other organizational actors (sub-themes: relationship with state, relationship with businesses and relationship with other NGOs); (3) beliefs, spirituality and moral authority; (4) social position of participants, (5) stakeholders’ mobilization and participation; (6) feelings; (7) social purpose; and (8) social change. These findings were later discussed under the lens of practice theory, and in this discussion I argue and show that, in the context studied: (a) even though SE embraces a wide variety of different social purposes, they are intertwined with a common notion of social change based on a general understanding and aspiration for social equality; (b) this social change is accomplished in a processual and ongoing manner as stakeholders from antagonistic social groups felt compelled to and participated in SE practices. In answering the proposed research question the contributions of this thesis are: (i) the elaboration a working definition for SE based on its relationship with social change; (ii) providing in-depth empirical evidence which accounts for and explains this relationship; (iii) characterizing SE in the Brazilian context and reflecting upon its transferability to other contexts. This thesis also makes a methodological contribution, for it demonstrates how thematic analysis can be used in practice-based studies.

A cultura de índio, seu menino, vem de longe aqui : formação histórica e territorialização dos Tremembé/CE

This dissertation is based on the ethnography of a strategic selection of three Tremembé ethnic situations, which are situated in the backlands of Acaraú and Itarema, municipalities located in Ceará State (Northeast Brazil). My main aims are the following. Firstly, I reconstitute the historical and social formation of three localities, called Lagoa dos Negros, Telhas, and Queimadas, related to a particular origin myth which refers to Almofala, an extinct colonial Aldeamento in the seashore, where the Tremembé indians and other native populations were converted and gathered under missionary administration. According to the origin myth, these three localities were set up after a strong drought which happened in 1888 (the so called three eights) when a group of Tremembé families moved to the countryside and established close to the Lagoa dos Negros and, later on, they were segmented into smaller groups which started to live in other areas and places not far from the former location. Notably, I develop an anthropological approach to understand the historical formation of these three localities. Secondly, I analyze some processes of territorialization, which were emerged from the 1980s and had important consequences to these indigenous families throughout the next two decades. This historical dimension is re-appropriated and ressignified in ethnic terms. A third point of my work is the analysis of the construction of territorialities and also the cultural and symbolic dimensions which are formulated by the Tremembé Indians who live in these localities. Therefore, I investigate some cultural traditions and rituals, such as the Torém dance, but I also examine their multiple semantics, which constitute a transversal direction throughout the history understood by the Tremembé of the different social situations I researched. To sum up, there is a process of cultural actualization, which is still going on and presents itself through the ludic sphere as well as their political and religions dimensions, which are usually associated to the ritual presentation of the Torém

Estudos de Durabilidade Frente ao Ataque Ácido de Compósitos Portland-Polímero para Cimentação de Poços de Petróleo

Portland-polymers composites are promising candidates to be used as cementing material in Northeastern oil wells of Brazil containing heavy oils submitted to steam injection. In this way, it is necessary to evaluate its degradation in the commonly acidizind agents. In addition, to identify how aggressive are the different hostile environments it is an important contribution on the decision of the acidic systems to be used in. It was investigated the performance of the Portland-polymer composites using powdered polyurethane, aqueous polyurethane, rubber tire residues and a biopolymer, those were reinforced with polished carbon steel SAE 1045 to make the electrochemical measurements. HCl 15,0 %, HCl 6,0 % + HF 1,5 % (soft mud acid), HCl 12,0 % + HF 3,0 % (regular mud acid) and HAc 10 % + HF 1,5 % were used as degrading environment and electrolytes. The more aggressive acid solution to the plain Portland hardened cement paste was the regular mud acid, that showed loss of weight around 23.0 %, followed by the soft mud acid, the showed 11.0 %, 15.0 % HCl with 7,0 % and, at last the 10.0 % HAc plus HF 1.5 % with just 1.0 %. The powdered polyurethane-composite and the aqueous polyurethane one showed larger durability, with reduction around 87.0 % on the loss of weight in regular mud acid. The acid attack is superficial and it occurs as an action layer, where the degraded layer is responsible for the decrease on the kinetic of the degrading process. This behavior can be seen mainly on the Portland- aqueous polyurethane composite, because the degraded layer is impregnated with chemically modified polymer. The fact of the acid attack does not have influence on the compressive strength or fratography of the samples, in a general way, confirms that theory. The mechanism of the efficiency of the Portland-polymers composites subjected to acid attack is due to decreased porosity and permeability related with the plain Portland paste, minor quantity of Ca+2, element preferentially leached to the acidic solution, wave effect and to substitute part of the degrading bulk for the polymeric one. The electrolyte HAc 10 % + HF 1,5 % was the least aggressive one to the external corrosion of the casing, showing open circuit potentials around +250 mV compared to -130 mV to the simulated pore solution to the first 24 hours immersion. This behavior has been performed for two months at least. Similar corrosion rates were showed between both of the electrolytes, around 0.01 μA.cm-2. Total impedance values, insipient arcs and big polarization resistance capacitive arcs on the Nyquist plots, indicating passivity process, confirm its efficiency. In this way, Portlandpolymers composites are possible solutions to be succeed applied to oilwell cementing concomitant submitted to steam injection and acidizing operation and the HAc 10,0 % + HF 1,5 % is the less aggressive solution to the external corrosion of the casing

Monitoramento da morfologia costeira em setores da bacia potiguar sob influência da indústria petrolífera utilizando geodésia de alta precisão e laser escâner terrestre

The objective of this Doctoral Thesis was monitoring, in trimestral scale, the coastal morphology of the Northeastern coast sections of Rio Grande do Norte State, in Brazil, which is an area of Potiguar Basin influenced by the oil industry activities. The studied sections compose coastal areas with intense sedimentary erosion and high environmental sensitivity to the oil spill. In order to achieve the general objective of this study, the work has been systematized in four steps. The first one refers to the evaluation of the geomorphological data acquisition methodologies used on Digital Elevation Model (DEM) of sandy beaches. The data has been obtained from Soledade beach, located on the Northeastern coast of Rio Grande Norte. The second step has been centered on the increasing of the reference geodetic infrastructure to accomplish the geodetic survey of the studied area by implanting a station in Corta Cachorro Barrier Island and by conducting monitoring geodetic surveys to understand the beach system based on the Coastline (CL) and on DEM multitemporal analysis. The third phase has been related to the usage of the methodology developed by Santos; Amaro (2011) and Santos et al. (2012) for the surveying, processing, representation, integration and analysis of Coastlines from sandy coast, which have been obtained through geodetic techniques of positioning, morphological change analysis and sediment transport. The fourth stage represents the innovation of surveys in coastal environment by using the Terrestrial Laser Scanning (TLS), based on Light Detection and Ranging (LiDAR), to evaluate a highly eroded section on Soledade beach where the oil industry structures are located. The evaluation has been achieved through high-precision DEM and accuracy during the modeling of the coast morphology changes. The result analysis of the integrated study about the spatial and temporal interrelations of the intense coastal processes in areas of building cycles and destruction of beaches has allowed identifying the causes and consequences of the intense coastal erosion in exposed beach sections and in barrier islands

Fungos ectomicorrízicos em áreas de Mata Atlântica do Nordeste do Brasil

Ectomycorrhizal associations are poorly known from tropical lowlands of South America. Recent field trips to the reserve Parque Estadual das Dunas in Natal, in Rio Grande do Norte state, Brazil, revealed a undocumented community of ectomycorrhizal fungi. This type of Mycorrhizal association is frequently in the north hemisphere in temperate and boreal forests. The aim of this work is to analyze the occurrence of ectotrophic areas in atlantic rainforest. Collections along and around the trails in the reserve revealed six genera of putatively ECM fungi which belong to the basidiomycete, Amanitaceae, Boletaceae, Russulaceae, Entolomataceae, and Sclerodermataceae family which are poorly documented in Brazil. Plants belonging to Myrtaceae, Polygonaceae, Leguminosae/Caesalpinioideae, Erythroxylaceae, Malphigiaceae, Bromeliaceae, Loganiaceae, Sapotaceae e Celastraceae were found living next to the species of fungi analized. Our results suggest that the area studied is an ectotrophic environment which shows high diversity of putatively ECM fungi and some plants probably host ECM. The tropical lands are a potential focus to study reinforced by the new records of Scleroderma in Brazil and Northwest of Brazil

Estudo estatístico sobre eventos de precipitação intensa no nordeste do Brasil

The Northeast of Brazil (NEB) shows high climate variability, ranging from semiarid regions to a rainy regions. According to the latest report of the Intergovernmental Panel on Climate Change, the NEB is highly susceptible to climate change, and also heavy rainfall events (HRE). However, few climatology studies about these episodes were performed, thus the objective main research is to compute the climatology and trend of the episodes number and the daily rainfall rate associated with HRE in the NEB and its climatologically homogeneous sub regions; relate them to the weak rainfall events and normal rainfall events. The daily rainfall data of the hydrometeorological network managed by the Agência Nacional de Águas, from 1972 to 2002. For selection of rainfall events used the technique of quantiles and the trend was identified using the Mann-Kendall test. The sub regions were obtained by cluster analysis, using as similarity measure the Euclidean distance and Ward agglomerative hierarchical method. The results show that the seasonality of the NEB is being intensified, i.e., the dry season is becoming drier and wet season getting wet. The El Niño and La Niña influence more on the amount of events regarding the intensity, but the sub-regions this influence is less noticeable. Using daily data reanalysis ERAInterim fields of anomalies of the composites of meteorological variables were calculated for the coast of the NEB, to characterize the synoptic environment. The Upper-level cyclonic vortex and the South atlantic convergene zone were identified as the main weather systems responsible for training of EPI on the coastland

Coptotermes gestroi (Isoptera: Rhinotermitidae) in Brazil: possible origins inferred by mitochondrial cytochrome oxidase II gene sequences

The Asian subterranean termite, Coptotermes gestroi, originally from northeast India through Burma, Thailand, Malaysia, and the Indonesian archipelago, is a major termite pest introduced in several countries around the world, including Brazil. We sequenced the mitochondrial COII gene from individuals representing 23 populations. Phylogenetic analysis of COII gene sequences from this and other studies resulted in two main groups: (1) populations of Cleveland (USA) and four populations of Malaysia and (2) populations of Brazil, four populations of Malaysia, and one population from each of Thailand, Puerto Rico, and Key West (USA). Three new localities are reported here, considerably enlarging the distribution of C. gestroi in Brazil: Campo Grande (state of Mato Grosso do Sul), Itajai (state of Santa Catarina), and Porto Alegre (state of Rio Grande do Sul).

Host specificity of a Brazilian isolate of Alternaria cassiae (Cenargen CG593) under greenhouse conditions

Several Alternaria cassiae isolates were recovered from diseased sicklepod plants (Senna obtusifolia) in the southern regions of Brazil. A representative isolate (Cenargen CG593) was tested for its host range under greenhouse conditions. The fungus promoted symptoms in sicklepod, cassava (Manihot dulce), tomato (Lycopersicon esculentum) and eggplant (Solanum melongena) when tested at a spore concentration of 10(6) spores ml(-1). When the plants were inoculated with a suspension of 10(5) spores ml(-1) and held at a dew period of 12 h (cassava) or 18 h (tomato and eggplant), the plants showed symptoms of the disease, but they recovered and continued their normal vegetative growth. These results show that the fungus A. cassiae is safe to use for the control of S. obtusifolia under Brazilian conditions, because it did not cause excessive damage in the three plants tested.

Fitossociologia de comunidades de plantas daninhas em agroecossistema cana-crua

Objetivou-se neste trabalho estudar a fitossociologia de comunidades de plantas daninhas de canaviais colhidos no sistema mecanizado, sem queima prévia da palha, e a similaridade entre talhões quanto à composição de espécies. Os levantamentos foram realizados em 28 talhões comerciais na região de Ribeirão Preto-SP. em cada talhão foram demarcadas áreas de coleta e avaliação, na proporção de duas por hectare, mantidas sem controle, e que serviram de local para as amostragens de plantas daninhas. As amostragens foram feitas com quadrados vazados (0,5 x 0,5 m), lançados aleatoriamente duas vezes em cada uma das áreas. Essas amostragens foram realizadas determinando-se a densidade e a biomassa específica aos 120 dias após o corte da cana. Cyperus rotundus foi a principal espécie, destacando-se quanto aos valores de importância relativa (IR). As plantas dicotiledôneas anuais de propagação por sementes também se destacaram, dentre as quais diversas espécies das famílias Euphorbiaceae e Convolvulaceae. em contrapartida, as gramíneas tradicionais de áreas de cana colhida queimada tiveram pouco destaque. O índice de Shannon (H) de diversidade de espécies das comunidades variou de 0 a 1,61, e o índice de similaridade entre os talhões (S) foi muito variável. A maioria das espécies ou grupo de espécies apresentou padrão agregado (V/m > 1,00), com valores relativamente altos de índice de agregação (V/m). Entretanto, na maioria dos casos, Cyperus rotundus e as Convolvulaceas apresentaram os maiores índices.
