Social entrepreneurship, microcredit and development challenges: a case study analysis of Banco Pérola

The term “social entrepreneurship” has been attracting growing interest from different sectors in the past years, driven by the possibility of employing business techniques to tackle recurrent social and environmental issues. At the forefront of this global phenomenon is microcredit, seen by many as an effective anti-poverty tool and having the Grameen Bank as its flagship program. While the prospects of social entrepreneurship seem promising, the newness of the concept and its somewhat confusing definition make conditions difficult to analyze this contemporary phenomenon. Therefore, the objective of this study was to discuss the challenges faced by social entrepreneurs and alternatives of development for social businesses through a case study on a Brazilian microcredit institution and inclusive business, Banco Pérola. The case addresses a growing need for case studies designed for teaching in the field of social entrepreneurship. It was focused mainly on understanding the development challenges within Banco Pérola, and built based on interviews carried out with top management, credit officer and clients of the institution, as well as on secondary data collected. An analysis of the case study was performed under a Teaching Notes. As illustrated by the Banco Pérola case, the main difficulties encountered by social entrepreneurs relate to the systematization of processes and creation of operational routines, including for performance evaluation (impact assessment tools); to the capture and management of both financial and human capital; to scaling up the business model and to the need of forging closer and more personal relationships with customers as against in traditional banking practices. In spite of certain limitations, such as the fact that the case might soon become outdated due to the fast-changing environment surrounding Banco Pérola, or the fact that not all relevant stakeholders (e.g. partners) were selected for interviews, the research objective has been achieved and the study can be seen as a contribution to spreading the concept of social entrepreneurship.

Microcrédito e empoderamento de mulheres: o caso do Banco Popular Crédito Solidário

Muitos estudos têm indicado a importância das microfinanças para a redução da pobreza e desigualdades sociais, incluindo o empoderamento feminino. Neste contexto, este trabalho teve como objetivo geral analisar o empoderamento das clientes de uma instituição de microfinanças – o Banco do Povo Crédito Solidário (BPCS), em Santo André (SP). Foi classificada como uma pesquisa qualitativa, descritiva e do tipo grounded theory e estudo de caso. Foram realizadas 10 visitas de campo a microempresárias e dois grupos focais com grupos solidários da instituição. Também foram entrevistados gestores e agentes de crédito. Foi realizada análise de conteúdo com auxílio do quadro teórico utilizado sobre de empoderamento econômico, social e individual. Os principais resultados mostram a crescente capacitação econômica no âmbito da aprendizagem do empreendedorismo, conhecimento em microfinanças e do seu próprio negócio. Por estes motivos, percebemos o aumento da interação social com a comunidade. Também percebemos a emancipação das trabalhadoras, muitas delas tem emancipação econômica dos seus maridos e algumas delas são capazes de contribuir financeiramente para o agregado familiar, melhorando assim a relação com o companheiro. Finalmente, este trabalho confirma a importância das microfinanças, o efeito positivo no empoderamento para a redução da pobreza e para a promoção da equidade de gênero. A principal conclusão observada foi a melhoria do nível de educação, empoderamento, autonomia e da compreensão de sua auto-capacidade e que elas são capazes de gerir seu próprio negócio e vidas; dessa forma, como contribuição teórica, foi elaborado o mapa conceitual de empoderamento auto-sustentável.

Os impactos das intervenções do Banco Central do Brasil sobre os movimentos intradiários do mercado futuro de dólar

Esse trabalho avalia a influência das intervenções do Banco Central do Brasil (BCB) sobre o mercado de moeda estrangeira entre outubro de 2011 e dezembro de 2014. Utilizando dados intradiários para as cotações da taxa de câmbio e para as intervenções, são analisados, através da metodologia de estudo de eventos, os impactos das intervenções sobre o nível e volatilidade da taxa de câmbio. Os resultados mostram que as intervenções, quando não são esperadas pelo mercado, influenciam a taxa de câmbio e o efeito varia com o tamanho da intervenção. Por outro lado, não há evidências claras de que a atuação do BCB no mercado de câmbio contribui para reduzir a volatilidade cambial no curto prazo.

Desenvolvimento e caracterização de filtros cerâmicos para aplicações a altas temperaturas

Ceramic filters are cellular structures that can be produced by various techniques, among which we highlight the replication method, or method of polymeric sponge. This method consists of impregnating polymeric foam with ceramic slurry, followed by heat treatment, where will occur decomposition of organic material and the sinter of the ceramic material, resulting in a ceramic whose structure is a replica of the impregnated sponge. Ceramic filters have specific properties that make this type of material very versatile, used in various technological applications such as filters for molten metals and burners, make these materials attractive candidates for high temperature applications. In this work we studied the systems Al2O3-LZSA ceramic filters processed in the laboratory, and commercial Al2O3-SiC ceramics filters, both obtained by the replica method, this work proposes the thermal and mechanical characterization. The sponge used in the processing of filters made in the laboratory was characterized by thermogravimetric analysis. The ceramic filters were characterized by compressive strength, flexural strength at high temperatures, thermal shock, permeability and physical characterization (density and porosity) and microstructural (MEV and X-rays). From the results obtained, the analysis was made of the mechanical behavior of these materials, comparing the model proposed by Gibson and Ashby model and modified the effective area and the tension adjusted, where the modified model adapted itself better to the experimental results, representing better the mechanical behavior of ceramic filters obtained by the replica method

Desenvolvimento de filtros cerâmicos impregnados com nanopartículas de prata para desinfecção de água potável

Brazil has vast amounts of hydric resources, whose quality has been deteriorating due to pollutant dumping. Household waste disposal is one of the main sources of water pollution, stimulating bacteria proliferation and introducing microorganisms, including those from fecal matter. Conventional water disinfection methods are a solution, but on the downside, they lead to the formation byproducts hazardous to human health. In this study, aiming to develop bactericidal filters for the disinfection of drinking water; silver nanoparticles were deposited on alumina foams through three routes: sputtering DC, dip coating and in situ chemical reduction of silver nitrate. The depositions were characterized through X-ray diffraction, scanning electron microscopy and EDS element mapping. The influence of the depositions on permeability and mechanical properties of the ceramic foams was assessed and, in sequence, a preliminary antibacterial efficiency analysis was carried out. Characterization results indicate that the chemical reduction routes were efficient in depositing homogeneously distributed silver particles and that the concentration of the metallic precursor salt affects size and morphology of the particles. The antibacterial efficiency analysis indicates that the chemical reduction filters have potential for water disinfection
