Desenvolvimento econômico e mercado de trabalho urbano no nordeste brasileiro

A história recente do Nordeste caracteriza-se por uma primeira fase de isolamento e outra de articulação. Nessa segunda fase, o dinamismo que se instala a partir da década de sessenta provocou profundas transformações na economia da região. Essas transformações implicaram em elevadas taxas de expansão do produto regional, alterações na estrutura produtiva através da adoção de novos processos de trabalho que implicou de um lado, na redução da demanda por trabalho e de outro, na sua expansão. Registrou-se, também, mudanças bastante significativas nos gêneros industriais reduzindo a participação na produção das indústrias de bens de consumo não-duráveis e aumentando de modo importante a participação das indústrias de bens intermediários voltadas para o mercado nacional e internacional, o que contribui para aumentar a dependência do Nordeste em relação as regiões mais ricas. As mudanças iniciadas no setor industrial se propagam para os setores primários, secundários e terciários. No setor agrícola, as transformações dificultaram a sobrevivência do trabalhador, ampliaram as relações capitalistas no setor manifestas na maior proletarização da mão-de-obra rural; estimularam as emigrações para. as cidades e elevaram consideravelmente a participação da população ocupada em atividades predominantemente urbanas. No setor terciário, as mudanças provocaram o incremento do subemprego, grande diferenciação nos 11 níveis de produtividade e rendimentos, gerando um quadro de aprofundamento da heterogeneidadeda estrutura produtiva e do mercado de trabalho. Adicionalmente, houve uma excessiva urbanização, aumento da concentração da renda, incremento do grau de informalidade, crescimento do número de empregados clandestinos e maior participação dos menores e adultos no mercado de trabalho. Tudo isso, ocorreu,associado ao quadro de dinamismo das atividades produtivas, sem paralelo na história recente das regiões atrasadas do pais. A análise dos dados também mostrou que o nível do desemprego aberto, é relativamente baixo tanto para os homens como para as mulheres. Isto ocorre porque na expansão ou na retração econômica as flutuações no nível de ocupação são acampanhadas por modificações da taxa de participação da PIA no mercado de trabalho. Portanto, a recente infonnalidade, fonnalidade e submersão da mão-de-obra no Nordeste estão associadas a um contexto de crescimento da economia e, por conseguinte, resultam do estilo ou padrão de acumulação de capital que, mesmo se realizando com altas taxas de expansão, não repercute positivamente no mercado de trabalho, nos tennos requeridos pela oferta de mão-de-obra. Assim, o aparecimento de um excedente relativo de população é resultado do padrão de acumulação da capital da economia regional, que está associado ao modo como o Nordeste se inseriu no contexto nacional e, nesse sentido, é o padrão de industrialização o principal fator responsável por parte importante do insucesso da economia local em absorver produtivamente a população que se apresenta no mercado de trabalho urbano

Factors influencing consumer decision in crowdfunding

Crowdfunding é um método recente e emergente de captar dinheiro para desenvolvimento de projetos (tanto orientados a lucro ou não) sem a intermediação tradicional de instituições financeiras, liberando empreendedores de custos, regulações e burocracia associada a essa prática. Além disso, também é um método de pré-testar novos produtos com um público selecionado e entusiasmado. O objetivo dessa dissertação é entender que fatores estão influenciando a decisão do consumidor de investir em projetos. A literatura contribui com: (1) fatores intrínsecos, como desejo de patronagem; (2) fatores extrínsecos, como a apresentação do projeto; e (3) pressão social. Há ainda fatores associados com o nível atual de captação e número de investidores, assim como tipo de projeto envolvido, sendo ele de caridade ou não. Além disso, atitudes também possuem um papel em afetar a decisão de compra. Para responder a pergunta de pesquisa, uma metodologia de duas fases foi usada: uma entrevista de profundidade para capturar intenção de investir e motivação, de forma a construir um processo de decisão que englobasse todas as possibilidades descritas pela literatura. Após essa pesquisa qualitativa, uma pesquisa quantitativa foi feita para validar as informações coletadas pela fase anterior e coletar dados adicionais para gerar uma associação entre intenção de investir e comportamento. Dentre as informações geradas pela fase qualitativa, temos o fato que a maioria dos investidores tiveram como principal motivação a compra do produto sendo oferecido como se eles estivessem participando de uma pré-venda. Entretanto, essa não foi a principal razão para o investidor de caridade. Além disso, os respondentes que pré-compraram os produtos o fizeram para única razão que esses produtos satisfizeram desejos que tinham. Esses desejos variavam, sendo desde saudade de jogos antigos como resolver um problema de organização da carteira. Outra característica da pré-compra foi que eles não investiam valores simbólicos, pela razão que se o fizessem não receberiam o produto em troca. Recompensas tiveram um grande papel em atrair os respondentes para investimento em valores maiores que consideravam anteriormente. Também é verdade para o investidor em caridade, que também doou mais. A fase quantitativa confirmou as informações acima e gerou informação extra sobre as categorias de produto. Projetos de caridade e arte concentraram a maioria dos respondentes que disseram que a principal razão para investir foi basicamente ajudar a desenvolver o projeto sem demandar um produto em retorno. Entretanto, outros projetos como Música também apresentaram altos números de comportamento caridoso, possivelmente por causa do envolvimento emocional com o artista. Outras categorias apresentaram um mix de razões para investir ou enviesado a comprar o produto apenas, o que pode ser explicado pelo efeito de recompensas e pelo fato que essas categorias estão simplesmente pré-vendendo produtos. Essa pesquisa também confirmou as principais fontes usadas para conhecer mais sobre os projetos: recomendação pessoal e blogs e fóruns. Outro resultado dessa fase foi o desenvolvimento de fatores a partir de frases atitudinais que puderam explicar intenção de investir. Seis fatores foram criados: Entusiasmo (por crowdfunding), Exclusividade (compra de recompensas), Caridade (doações pequenas para ajudar o desenvolvimento do projeto), Cautela (similar à difusão de responsabilidade, isto é, espera por mais investidores para dar o primeiro passo), Intimidade (projeto foi recomendado ou há ligação emocional com o criador) e Compartilhamento (compartilhar para ajudar a trazer mais investidores para o projeto). Categorias com alto envolvimento emocional apresentaram associação com Intimidade, como música, filme e tecnologia. Dado o fato que a amostra não continha muitos entusiastas por crowdfunding, esse fator não apresentou qualquer associação com as categorias. Categorias que não entregam produtos em troca, como comida e fotografia, apresentaram altos níveis de associação com o fator caridade. Compartilhamento é altamente associado com tecnologia, dado o fato que essa categoria concentra os respondentes que são mais orientados à inovação e entusiastas sobre o produto, então precisam compartilhar e gerar boca-a-boca para ajudar a atingir a meta de investimento.

As Faces e os Disfaces da Informalidade no Capitalismo Conteporâneo: Um Estudo do Comércio de Rua em Pau dos Ferros/RN

This paper discusses the expression of informality in contemporary capitalism. Thematic of relevance to the analysis of the reality of work today and the logic that moves the capital, its real presence in the lives of individuals. The street trading of Pau dos Ferros town, popularly known as "street market" was chosen as the search space. The main objective is to seize and examine the articulations and logic, present in the configuration of the street trading of this city, located in the state of Rio Grande do Norte, explaining the functionality of informality for capitalist accumulation, but also for the reproduction of segments of the working class. Our analysis is based in the perspective of totality, trying to grasp the historical determinations of the phenomenon in focus. It includes the analysis of the mechanisms used by the capital to reproduce itself in the current historical context, which has been implicated in the composition of the labor markets of different countries and in various forms of exploitation to which workers in general are subject. It also means discussing the development of capitalism in Brazil, the logic that permeates its dependence, and especially the use of over-exploitation of labor, as a lever for internal accumulation. The course of investigation consisted of theoretical research to form the basis of theoretical and methodological analysis and to outline the context in which our research object is inserted, and field research conducted in two phases: systematic observation, which allowed to map traders features and the infrastructure of commerce, and the conduction of interviews with key informants. The material collected was scrutinized according to analytical scheme inspired by the content analysis. Among the main considerations developed from the research process we include: the street trading of Pau dos Ferros remains shrouded in the majority sale of agricultural products, this demonstrates the structural characteristics of the region. However, the supply of this product is no longer restricted to the excess of small local producers. The presence of the dealer changed the distribution of the product, streamlining it. In parallel, business practices are developed, practices in which traded goods (industrial) reflect the moment of capitalist restoration, a larger business network. The reflections also made it possible to show that street trading follows developing on the basis of informal work, which gains functionality to the system, as it is configured as a space commonly used to drain part of the production, of industries (clothing/shoes), especially if the distribution is considered as an essential element of the complex process that aims at capital appreciation. This activity has been functioning as a place of employment and income generation for the subjects who are away from formal employment, masking, this way, unemployment, moreover, they allow them to continue as consumers. Such expressions reflect the ability and the logic of capital to expand and aggregate into so many realities. It is underway today, the logic that has led many workers to join the project of domination of capital, by the illusory chance to become capitalists. The aim has been to turn the subject into a consumer and the worker an enterprising

Development of a novel fermented soymilk product with potential probiotic properties

The study was carried out to test the ability of Enterococcus faecium, Lactobacillus acidophilus, L. jugurti, Streptococcus thermophilus and L. delbrueckii ssp bulgaricus to decrease cholesterol in vitro and to grow in the presence of bile salts. Both properties were dependent on the species under study. The cultures were also inoculated into soymilk fortified with dry milk whey powder as single or mixed starters. The physicochemical and sensory evaluations of the fermented products showed that E. faecium plus L. jugurti (ratio 1:1) is the best combination, and this mixture also produces a 43% decrease in cholesterol. © Springer-Verlag 1999.

Development and validation of a simple, rapid and stability-indicating high performance liquid chromatography method for quantification of norfloxacin in a pharmaceutical product

A stability-indication high performance liquid chromatographic method has been developed for the determination of norfloxacin in tablet dosage forms. Optimum separation was achieved in less than 7 minutes using Eclipse Plus Zorbax C18 Agilent, 150 mm×4.6 mm i.d., 5 μm particle size column. The analyte was resolved by using a mobile phase 5% acetic acid aqueous solution and methanol (80:20, v/v) at a flow rate 1.0 ml/min on an isocratic high performance liquid chromatographic system at a wavelength of 277 nm. Linearity, system suitability, precision, sensitivity, selectivity, specific, and robustness were established by International Conference Harmonization guidelines. For stress studies the drug was subjected to photolysis, oxidation, acid, alkaline and neutral conditions. The analytical conditions and the solvent developed provided good resolution within a short analysis time and economic advantages. The proposed method not required sophisticated and expensive instrumentation.

Guidelines for the Brazilian ceramic sector strategic development, based on a comparison with the Italian market

Based on a structured literature review, the ceramic tiles sector of Italy (benchmark) and Brazil (2nd world producer and consumer) are compared, under four strategic factors: normative, market, technology and strategic management, in order to identify critical risks for a national strategic sector. The document aims to propose guidelines for a strategic re-planning of the Brazilian ceramic tiles sector, making the Brazilian producers aware of the national market fragility (in spite of its recent remarkable evolution) and helping the policy makers to reflect on the need of reviewing the strategic planning methods and practice, of designing new targeted programs (based on coherence between operation and business strategies), of providing improved management to strengthen the sector against unfair competition by low-cost producers, enhancing the necessary infrastructure in technology, work, marketing and quality management. The analysis is limited to the single-firing production technology. The wide-coverage strategic analysis of the Brazilian ceramic tiles sector, very little studied until now in a scientific way, emphasizes the importance of applying research methodology and may be valuable to both scholars and practitioners. Additionally, it highlights the need of investments in innovation (product design and production technology) and the fundamental role of the sector organization, identifying different dimensions. It is possible to conclude that the recent Brazilian production growth is not due to a natural strengthening because of the hit of the sector and of correct enterprises strategy, but it seems the result of a temporary and favorable economic contingency.

Development of a high sensitive automatic setup for screening of microcystins in surface waters by employing a LED-based photometric detector

In this manuscript, an automatic setup for screening of microcystins in surface waters by employing photometric detection is described. Microcystins are toxins delivered by cyanobacteria within an aquatic environment, which have been considered strongly poisonous for humans. For that reason, the World Health Organization (WHO) has proposed a provisional guideline value for drinking water of 1 mu g L-1. In this work, we developed an automated equipment setup, which allows the screening of water for concentration of microcystins below 0.1 mu g V. The photometric method was based on the enzyme-linked immunosorbent assay (ELISA) and the analytical signal was monitored at 458 nm using a homemade LED-based photometer. The proposed system was employed for the detection of microcystins in rivers and lakes waters. Accuracy was assessed by processing samples using a reference method and applying the paired t-test between results. No significant difference at the 95% confidence level was observed. Other useful features including a linear response ranging from 0.05 up to 2.00 mu g L-1 (R-2 =0.999) and a detection limit of 0.03 mu g L-1 microcystins were achieved. (C) 2011 Elsevier B.V.

Technology Development and Consumer Acceptance of Innovation in Fruit Production

Precision Agriculture (PA) and the more specific branch of Precision Horticulture are two very promising sectors. They focus on the use of technologies in agriculture to optimize the use of inputs, so to reach a better efficiency, and minimize waste of resources. This important objective motivated many researchers and companies to search new technology solutions. Sometimes the effort proved to be a good seed, but sometimes an unfeasible idea. So that PA, from its birth more or less 25 years ago, is still a “new” management, interesting for the future, but an actual low adoption rate is still reported by experts and researchers. This work aims to give a contribution in finding the causes of this low adoption rate and proposing a methodological solution to this problem. The first step was to examine prior research about Precision Agriculture adoption, by ex ante and ex post approach. It was supposed as important to find connections between these two phases of a purchase experience. In fact, the ex ante studies dealt with potential consumer’s perceptions before a usage experience occurred, therefore before purchasing a technology, while the ex post studies described the drivers which made a farmer become an end-user of PA technology. Then, an example of consumer research is presented. This was an ex ante research focused on pre-prototype technology for fruit production. This kind of research could give precious information about consumer acceptance before reaching an advanced development phase of the technology, and so to have the possibility to change something with the least financial impact. The final step was to develop the pre-prototype technology that was the subject of the consumer acceptance research and test its technical characteristics.

Assimilation and contrast in web product reviews: devaluing the recommendation of a proficient but dissimilar reviewer

When viewing web-consumer reviews consumers encounter the reviewers in an anonymous environment. Although their interactions are only virtual they still exchange social information, e.g. often reviewers refer to their proficiency or consumption motives within the review texts. Do these social information harm the viewers’ perception of the recommended products? The present study addresses this question by applying the paradigm of social comparison (Mussweiler, 2003) to web-consumer reviews. In a laboratory experiment with a student sample (n = 120) we manipulated the perceived similarity between reviewer and viewer and the perceived proficiency of the reviewer. A measurement of achievement goals (Elliott & McGregor, 2001) and average number of hours of study prior to the experiment allowed to introduce the reviewer as high [low] in proficiency and similar [dissimilar] in achievement goals. As predicted, the viewer’s evaluation of the recommended products differed as a function of this social information. Contrasting with the reviewer led to devaluing the products recommended by a proficient but dissimilar reviewer. However, against our prediction social comparison with the reviewer did not affect the viewer`s self-evaluation. Whether social information in web-product reviews affects the viewer`s self-evaluation and induces both social comparison processes remains an open question. Future studies aim to address this by manipulating the informational focus of the viewer, rather than the perceived similarity between viewer and reviewer. So far, the present study extends the application of social comparison to consumption environments and contributes to the understanding of the virtual social identity.

The Garment Industry in Cambodia: Its Role in Poverty Reduction through Export-Oriented Development

Cambodia's export-oriented garment industry has contributed greatly to poverty reduction in the country through employment of the poor. This paper provides a statistical verification of this contribution based on firm-level data from 164 sampled companies collected in 2003. Its main conclusions confirm the substantial impact that employment in the garment industry has had on poverty reduction in Cambodia. Firstly, entry-level workers receive wages far above the poverty line. Secondly, females make up the predominant share of the main category jobs in the industry. Thirdly, barriers to employment and to promotions up to certain job categories are not high in terms of education and experience. Another important finding is that a typical sample firm exhibited high profitability, although there was wide variation in profitability among firms. This average of high profitability could be a good predictor of Cambodia's viability in the intensified competition since the phase out of the Multi-Fiber Arrangement (MFA) at the beginning of 2005. A point of note is that Cambodia's pattern of industrial development led by a labor-intensive industry is similar to that of neighboring countries in East Asia which earlier went through the initial stage of industrial development, except that Cambodia has lacked a strong government industrial promotion policy which characterized the earlier group.
