Relações interorganizacionais e eficiência coletiva: um estudo de caso no arranjo produtivo local de confecções do agreste pernambucano

This work is a study in the Local Productive Arrangement of confections from Agreste of Pernambuco, as a relevant sector in economic and social aspect. This research has as central aim to understand how the inter-organizational relations influence the collective efficiency of arrangement. The theoretical framework employed highlights the approaches that deal with the benefits of business agglomeration for the develop­ment of firms and regions. It has discussed the approach of small and medium enter­ prises and industrial districts (SCHMITZ, 1997), which introduce the concept of col­ lective efficiency, explaining that only those externalities explained by Marshall (1996) are not sufficient to explain the competitive advantage of enterprises, expand­ing the idea that organizations achieve competitive advantage not acting alone. To examine the influences of relations in the collective efficiency, it has been taken as analytical perspective theory of social networks (GRANOVETTER, 1973, 1985; BURT, 1992; UZZI, 1997) because it has believe that this approach provides subsi­ dies for a structural analysis of social relationships in face the behavior of human ac­tion. By examining the organizations in a social network, you should understand the reason of this establishment of the relationship, their benefits, and as the information flow takes place and density of links between the actors (Powell; SMITH-DOERR, 1994). As for the methods, this study is characterized as a case study, in according to the purposed objectives, in addition to qualitative method. Also, due to recovering of the historical milestones of the arrangement, it is used a sectional approach with longitudinal perspective (VIEIRA, 2004). The primary and secondary data were used in order to understand the evolutionary process of the sector and their inter-actors re­ lationships in the arrangement for the promotion of development, for both, was used the contend and documentary analysis technique, respectively (DELLAGNELO ; SIL­VA, 2005). The approach of social networks has permitted understand that social re­lationships may extend the collective efficiency of the arrangement, and therefore need to develop policies that encourage the legalization of informal companies in ar­rangement, by showing up themselves representative. Thus, the relations estab­ lished in LPA of confections from Agreste of Pernambuco need for more effective mechanisms to broaden the collective efficiency. Therefore, this way as take place has directly benefited only a group of companies that are linked in some way the sup­portive institutions. So we can conclude that the inter-actor relations have limited the collective efficiency of LPA, being stimulated by the institutions in support only to groups of entrepreneurs, even those that produce external relations for all clustered companies

A importância do microcrédito para os empreendedores: um estudo com os grupos solidários de Fortaleza /CE

This study aims to understand the changes in the improvement of economic and social conditions of small entrepreneurs who participate in solidarity groups linked to the Non-Governmental Organization (NGO) "X" in Fortaleza city, Ceará, through the use of productive-guided microcredit. It is come a research in exploratory and descriptive nature, with a quantitative and qualitative approach. Data were collected from the small entrepreneurs by applying a questionnaire, as well as through structured interviews with group leaders. They were worked on issues relating to income generation, employment generation, housing and health conditions, dietary pattern and leisure activities of small entrepreneurs and their families before and after the union to solidarity groups and use of productive-guided microcredit. The research showed that the use of microcredit has interfered with social and economic life of these small entrepreneurs, generating positive effects

Os programas de incentivo à cultura e o processo de fomento às organizações culturais no rio grande do norte: o caso da Casa da Ribeira em Natal

Since the emergence of the first demands for actions that were intended to give greater attention to culture in Brazil, came the first discussions which concerned the way the Brazilian government could have a positive influence in encouraging the culture, as is its interaction with the actors interested and involved with the cause. During the military dictatorship, there were programs which relied on the direct participation of the State to ensure that right, from the viewpoint of its support and implementation of public resources in developing the "cultural product" to be brought to society in its various forms of expression - all this, funded by the government. It is an example of "EMBRAFILMES" and "Projeto Seis e Meia", continued until the present day in some regions of the country, though maintained by entities not directly connected with the administration or the government. However, it was from the period of democratization and the end of the dictatorship that the Brazilian government began to look at the different culture, under its guarantee to the society. Came the first incentive laws, led by "Lei Sarney" Nº 7.505/86, which was culture as a segment which could receive foreign assistance in order to assist the government in fulfilling its public duty. After Collor era and the end of the embargo through the encouragement of culture incentive laws, consolidated the incentive model proposed in advance of Culture "Lei Sarney" and the federal laws, state and local regimentares as close to this action. This applies to the Rouanet Law (Lei Rouanet), Câmara Cascudo Law (Lei Câmara Cascudo) and Djalma Maranhão Cultural Incentive Law (Lei de Incentivo à Cultura Djalma Maranhão), existing in Natal and Rio Grande do Norte. Since then, business entities could help groups and cultural organizations to keep their work from the political sponsorship under control and regiment through the Brazilian state in the form of their Cultural Incentive Law. This framework has contributed to the strengthening of NGOs and with the consolidation of these institutions as the linchpin of Republican guaranteeing the right to access to culture, but corporate social responsibility was the one who took off in the segment treated here, through the actions of Responsibility Cultural enterprises arising from the Cultural Organizations. Therefore, in the face of this discourse, this study ascertains the process of encouraging the Culture in Rio Grande do Norte from the Deviant Case Analysis at the Casa da Ribeira, the main Cultural Organization that operates, focused action in Natal in order to assess the relationships established between the same entity and the institutions which are entitled to maintain the process of encouraging treated in this study - Enterprise, from the viewpoint of corporate sponsorship and Cultural Responsibility and State in the form of the Laws Incentive Funds and Public Culture Incentive

Desempenho e eficiência biológica de bubalinos de três grupos genéticos terminados em confinamento e abatidos em diferentes estádios de maturidade

Neste trabalho objetivou-se estudar o desempenho e a eficiência biológica de 48 bubalinos (16 Murrah - MUR, 16 Jafarabadi - JAF e 16 Mediterrâneo - MED) com média de 18 meses de idade e de peso vivo inicial de 330 kg terminados em confinamento. Quatro animais de cada grupo genético foram designados por sorteio para o abate inicial e serviram de referência para o estudo dos pesos iniciais de corpo vazio e de carcaça. Os 12 animais restantes de cada grupo genético foram divididos aleatoriamente em três subgrupos de quatro animais e submetidos aos seguintes tratamentos: Maturidade 1 (400 kg PV ao abate); Maturidade 2 (450 kg PV ao abate); Maturidade 3 (500 kg PV ao abate). Foi fornecida uma ração única, ad libitum, para todos os animais, composta por 50% de feno de coastcross na MS e 50% de concentrado à base de fubá de milho, uréia e farelo de soja, devidamente suplementado com minerais. Após os abates pré-fixados, determinou-se o peso corporal vazio (PCVZ) dos animais, por meio do somatório das partes integrantes do corpo. Os consumos médios diários de MS e MO não diferiram entre grupos genéticos, embora animais JAF tenham apresentado os maiores valores numéricos. Animais MUR, JAF e MED não diferiram quanto aos ganhos de peso corporal vazio e de carcaça. Não houve diferenças quanto à eficiência biológica (ganho de peso corporal vazio e ganho de carcaça por unidade de energia metabolizável ingerida) entre os grupos genéticos, embora animais Murrah tenham apresentado os maiores valores. Bubalinos abatidos aos 400 e 450 kg apresentaram melhor eficiência de ganho de peso corporal vazio e ganho de carcaça que os abatidos aos 500 kg.

Características quantitativas da carcaça de bubalinos de três grupos genéticos terminados em confinamento e abatidos em diferentes estádios de maturidade

Objetivou-se estudar as características quantitativas da carcaça de 36 bubalinos (12 Murrah 12 Jafarabadi e 12 Mediterrâneo), com idade média de 18 meses e peso vivo inicial de 330 kg, terminados em confinamento. Os 12 animais de cada grupo genético foram divididos aleatoriamente em três subgrupos de quatro animais e submetidos aos seguintes tratamentos: Maturidade 1: 400 kg PV ao abate; Maturidade 2: 450 kg PV ao abate; Maturidade 3: 500 kg PV ao abate. Durante o experimento, uma ração única, em que 50% da MS foi composta por volumoso, foi fornecida, ad libitum, para todos os animais. Após os abates pré-fixados, determinou-se o peso corporal vazio (PCVZ) dos animais pelo somatório das partes integrantes do corpo. Não houve diferença entre grupos genéticos e maturidades, em relação à porcentagem dos cortes dianteiro, paleta, traseiro total e alcatra completa. O rendimento de traseiro especial foi maior nos animais abatidos aos 400 kg PV e menor naqueles com 500 kg PV, enquanto o dos animais com 450 kg PV não diferiu dos demais. O rendimento de ponta-de-agulha, por sua vez, foi maior nos animais com 500 kg PV e menor nos com 400 kg PV. Os valores observados nesses dois pesos de abate não diferiram do obtido nos animais com 450 kg. A produção de carne a partir das raças Murrah, Jafarabadi e Mediterrâneo criadas no Brasil não difere quanto aos rendimentos de carcaça, traseiro, dianteiro e dos principais cortes básicos de interesse comercial.

Religião e cultura local: estudo de dois grupos espíritas potiguares

The subject of this research is the spiritual religious field, connected with the local cultural perspectives. Its basis is the analysis of two spiritual groups settled in Natal/RN: The Spiritual Group Evangelho no Lar and the Spiritual Center Garimpeiros da Luz . These two groups represent a point of convergence of several sectors of this religion, either through its insertion in the local sphere or in contact to nationally influent leaders, like the mediums Francisco Cândido Xavier and Divaldo Pereira Franco. Then, it aims to reach the potiguar singularities in their spiritualism approaches, looking for an analyses to possible connections between local values and themes from the spiritualism largely developed in Brazil. So, its objective is to act in the scope of influence, references, representations and adaptive practices in a local context, and they signalize special practices . The approaches until now developed refer only to the living of a Brazilian spiritualism, perfectly developed in contact with the catholic substrate, but there s still a gap about the local observation, with its peculiarities, which its research aims to disclosure. The option for a qualitative approach, in perfect relationship with the nature of the questions which were made was considered as an appropriate way to guide the study. To reach this, it will be made an ethnography of the studied groups, not only in the use of open interviews with its members but also in the contact and observation of its religious behavior, for example: meeting for studies of the doctrine, mediunic meetings, public lectures, helping the public in general. As results of this research we can point to the delimitation of local cultural references, which are undeniable, in relation to the identification of RN personalities who are considered coordinators or active spirits in the work performed by the groups. Thus, Auta de Souza, poetess and woman of great religiosity, Augusto Severo de Albuquerque Maranhão, martyr of the aeronautics, Father João Maria, object of popular devotion and Abdias Antônio de Oliveira, ex president of the Spiritual Federation of RN, present themselves as spiritual beings who lead the adaptability to the local context. In such a context, we have to point out the work of mediums, who, having a specific charisma, interacted with the groups in the establishment of these cultural bridges already made in their own contexts (national level), through the work equally possible to be locally reproduced. This and other facts, point out to perspectives of cultural circularity , including referring to a greater linking to sub layers in a true zone that converges and has circulation between an erudite spiritualism with another one, turned to the incorporation of local and popular elements

Digestibilidade Aparente da Proteína Bruta e dos Componentes da Parede Celular de uma Ração Completa, com Bovinos de Diferentes Grupos Genéticos

Avaliaram-se os coeficientes de digestibilidade do extrato etéreo (EE), proteína bruta (PB), fibra em detergente neutro (FDN), fibra em detergente ácido (FDA), hemicelulose (HCEL) e celulose (CEL) de uma ração completa, composta por 44,3% de feno de braquiária, 55% de concentrado e 0,7% de mistura mineral, fornecida a bovinos de diferentes grupos genéticos (Gir, Nelore, Guzerá, Santa Gertrudis e Caracu), pelas metodologias de coleta total de fezes e com indicador interno (lignina em detergente ácido - LDA), em delineamento inteiramente casualizado, com três repetições por grupo genético, com análise de variância individual dentro de cada metodologia e uma análise de correlação entre as metodologias. Não houve diferença entre grupos genéticos para a digestibilidade de EE, PB, FDN, FDA, HCEL e CEL, pelas metodologias de coleta total de fezes e com LDA, com médias de 44,28 e 40,38%; 52,46 e 49,51%; 57,04 e 54,25%; 37,71 e 34,04%; 71,66 e 69,68%; e 48,27 e 45,20%, respectivamente. As digestibilidades da PB, FDA e CEL não mostraram correlação. A LDA foi eficiente na estimativa da digestibilidades e os nutrientes foram utilizados de forma semelhante pelos diferentes grupos genéticos.

Digestibilidade dos nutrientes de uma ração completa, em bovinos de diferentes grupos genéticos

Avaliou-se a digestibilidade dos nutrientes de uma ração completa fornecida a bovinos de diferentes grupos genéticos. A digestibilidade foi estimada pela Lignina em Detergente Ácido, em delineamento de blocos ao acaso, com repetição no tempo. Foram efetuadas análises químicas da ração e das fezes, a cada 28 dias. de cada grupo genético foram colhidas fezes de 16 animais, no mínimo, a cada 28 dias. Observaram-se diferenças no aproveitamento dos nutrientes, destacando-se o Guzerá em todas as variáveis, com exceção da proteína bruta e da fibra em detergente ácido. Por outro lado, o Caracu mostrou-se menos eficiente na digestibilidade dos nutrientes, com exceção da proteína bruta e da fibra em detergente ácido.

Digestibilidade aparente da matéria seca, matéria orgânica e energia bruta e nutrientes digestíveis totais de uma ração completa para bovinos de diferentes grupos genéticos

Avaliou-se a digestibilidade da matéria seca (DMS), matéria orgânica (DMO) e energia bruta (DEB) e os nutrientes digestíveis totais (NDT) de uma ração completa, composta por 44,3% de feno de capim-braquiaria, 55% de concentrado e 0,7% de mistura mineral, fornecida a bovinos de diferentes grupos genéticos (Gir, Nelore, Guzerá, Santa Gertrudis e Caracu), pelas metodologias de coleta total de fezes e com indicador interno (lignina em detergente ácido -- LDA), em delineamento inteiramente casualizado, com três repetições por grupo genético, com análise de variância individual dentro de cada metodologia e uma análise de correlação entre as metodologias. As correlações foram médias ( 0,47 a 0,51) e significativas (P<0,0602; P<0,0697; P<0,0747; P<0,0522), respectivamente, para DMS, DMO, DEB e para NDT. A recuperação do indicador (95,06%) foi semelhante entre os grupos genéticos. Não houve diferença entre grupos genéticos para DMS, DMO, DEB e nos valores de NDT pelas metodologias de coleita total de fezes e com LDA, com médias de 53,31 e 50,33; 55,16 e 52,25; 52,22 e 49,20; e 53,39 e 50,61%, respectivamente. Assim, a LDA foi eficiente na estimativa da digestibilidade, em função de sua adequada recuperação. Os nutrientes foram utilizados de forma semelhante pelos grupos genéticos.

Técnicas de análise multivariada na determinação de grupos homogêneos de produtores de leite

Nesta pesquisa objetivou-se captar a variedade de situações tecnológicas para identificar grupos de produtores, o mais semelhante possível, no conjunto de variáveis e características selecionadas. Foram considerados 72 produtores, 8,33% da amostra total, selecionados conforme 29 variáveis relacionadas a fatores produtivos. Avaliaram-se as variáveis de melhor representatividade dentro de cada fator e suas comunalidades dentro do conjunto de fatores analisados. Para a avaliação desses resultados, foram utilizados métodos de análise fatorial em componentes principais. Posteriormente, aplicou-se o método de análise de agrupamentos. O pluralismo tecnológico requer análises de agrupamento para viabilizar intervenções técnicas diferenciadas, o que permite a consolidação de condições de sustentabilidade a partir das reais necessidades de incorporação tecnológica dos produtores.

A perda de grupos funcionais em comunidades virtuais: efeito das interações entre espécies e grupos funcionais

High levels of local, regional, and global extinctions has progressively simplified communities in terms of both species and ecosystem functioning. Theoretical models demonstrated that the degree of functional redundancy determines the rates of functional group loss in response to species extinctions. Here, we improve the theoretical predictions by incorporating in the model interactions between species and between functional groups. In this study, we tested the effect of different scenarios of interspecific interactions and effects between functional groups on the resistance to loss of community functional groups. Virtual communities have been built with different distribution patterns of species in functional groups, both with high and low evenness. A matrix A was created to represent the net effect of interspecific interactions among all species, representing nesting patterns, modularity, sensitive species, and dominant species. Moreover, a second matrix B was created to represent the interactions between functional groups, also exhibiting different patterns. The extinction probability of each species was calculated based on community species richness and by the intensity of the interspecific interactions that act upon it and group to which it belongs. In the model, successive extinctions decrease the community species richness, the degree of functional redundancy and, consequently, the number of functional groups that remain in the system. For each scenario of functional redundancy, A, and B, we ran 1000 simulations to generate an average functional extinction curve. Different model assumptions were able to generate remarkable variation on functional extinction curves. More extreme variations occurred when the matrix A and B caused a higher heterogeneity in the species extinction probability. Scenarios with sensitive species, positive or negative, showed a greater variation than the scenarios with dominant species. Nested interactions showed greater variation than scenarios where the interactions were in modules. Communities with maximal functional evenness can only be destabilized by the interactions between species and functional groups. In contrast, communities with low functional evenness can have its resistance either increased or decreased by the interactions. The concentration of positive interactions in low redundancy groups or negative interactions in high redundancy groups was able to decrease the functional extinction rates. In contrast, the concentration of negative interactions in low redundancy groups or positive interactions in high redundancy groups was able to increase the functional extinction rates. This model shows results that are relevant for species priorization in ecosystem conservation and restoration

Viabilidade econômica dos consórcios de grupos de alface e rúcula, em duas épocas de cultivo

It was evaluated the intercropping of lettuce groups economically with roquette, in two experiments, it was carried at Unesp, Jaboticabal-SP. The economical analyses were accomplished with prices of May and September of 2005. The total operational costs (COT) of the intercropping between crisp lettuce and roquette; looseleaf lettuce and roquette; and crisphead lettuce and roquette were from 14,8% to 95,6% highest to the of the singly cultivations of the cultures. The intercropping were shown profitable, the largest gross and liquid revenues happened in established intercropping with crisphead lettuce and roquette, in the Autumn-Winter, and with crisp lettuce and roquette, in the Spring.
