Structural Investigation of MFe(2)O(4) (M = Fe, Co) Magnetic Fluids

Ferrites of the type M(II)Fe(2)O(4) (M = Fe and Co) have been prepared by the traditional coprecipitation method. These ferrites were modified by the adsorption of fatty acids derived from soybean and castor oil and were then dispersed in cyclohexane, providing very stable magnetic fluids, readily usable in nonpolar media. The structural properties of the ferrites and modified ferrites as well as the magnetic fluids were characterized by XRD (X-ray powder diffraction), TEM (transmission electron microscopy), DRIFTS (diffusion reflectance infrared Fourier transform spectroscopy), FTMR (Fourier transform near-infrared), UV-vis, normal Raman spectroscopy, and surface-enhanced Raman scattering (SERS). XRD and TEM analysis have shown that the magnetic nanoparticles (nonmodified and modified) present diameters in the range of 10-15 nm. DRIFTS measurements have shown that the carboxylate groups of soybean and castor oil fatty acids adsorb on the ferrite surface, forming three different structures: a bridging bidentate, a bridging monodentate, and a bidentate chelate structure. The FTIR and Raman spectra of nonmodified Fe(3)O(4) and CoFe(2)O(4) nanoparticles have shown that the number of observed phonons is not compatible with the expected O(h)(7) symmetry, since IR-only active phonons were observed. in the Raman spectra and vice versa. SERS measurements of a CoFe(2)O(4) thin film on a SERS-active gold electrode at different applied potentials made possible the assignment of the signals near 550 and 630 cm(-1) to Co-O motions and the signals near 470 and 680 cm(-1) to Fe-O motions.

Synthesis, characterization and adsorption properties of porous mixed valent diruthenium(II,III)-terephthalate and diruthenium(II,III)-adipate polymers

Two porous mixed valent diruthenium(II,III)-dicarboxylate compounds have been prepared and characterized by spectroscopic methods, X-ray diffraction and thermogravimetry. Crystalline solids of [Ru(2)(tere)(2)Cl] center dot 3.5H(2)O (tere=terephthalate) and [Ru(2)(adip)(2)Cl] center dot 1.5H(2)O (adip=adipate) consist of extended chains in which polymeric layers of multiply metal-metal bonded [Ru(2)](5+) cores are bridged by dicarboxylate ligands in paddlewheel type geometries. Units of [Ru(2)(dicarboxylate)(2)](n)(+) are linked by axial bridging chloride ions generating three-dimensional networks. The polymers loose non-bonded water molecules at low temperatures but do not undergo thermal decomposition below 280-300 degrees C. Both of compounds exhibit high BET surface areas, [Ru(2)(tere)(2)Cl]: 235 m(2) g(-1) and [Ru(2)(adip)(2)Cl]: 281 m(2) g(-1), and occlude similar numbers of mol of N(2) per mol of metal. The terephthalate ligand generated an organized structure with supermicropores (total pore size of 0.24 cm(3) g(-1)) while the adipate ligand led to a mesoporous structure (total pore sizes of 0.47 cm(3) g(-1)) for the corresponding diruthenium(II,III)-dicarboxylate polymers.

Triangular ruthenium acetate clusters containing the bis(pyridyl)propane ligand and their inclusion chemistry with beta-cyclodextrin

The triruthenium carboxylate cluster [Ru(3)O(OAc)(6)(py)(2)(bpp)](+) (OAc = acetate) containing the bridging 1,3-bis(4-pyridyl)propane (bpp) ligand, and its dimeric species [{Ru(3)O(OAc)(6)(py(2))}(2)(mu-bpp)](2+) were synthesized in order to investigate their inclusion compounds with beta-cyclodextrin (beta-CD). Characterization of the complexes was carried out based on spectroscopic, electrochemical and spectroelectrochemical techniques, while the formation of inclusion complexes was evaluated using (1)H NMR/NOESY spectroscopy. Since bpp is a flexible ligand, a DFT study was carried out in order to characterize its conformational isomers and their possible role in the host-guest chemistry with beta-CD. Instead of observing the formation of inclusion compounds with different stoichiometries, we observed the formation of 1:1 bpp/beta-CD compounds in which the bpp ligand assumes different conformations. The assembly of polymetallic rotaxane species was successfully demonstrated by monitoring the (1)H NMR spectra of the monomeric cluster species in the presence of aquapentacyanoferrate(II) ions and beta-CD.

New insights on surface-enhanced Raman scattering based on controlled aggregation and spectroscopic studies, DFT calculations and symmetry analysis for 3,6-bi-2-pyridyl-1,2,4,5-tetrazine adsorbed onto citrate-stabilized gold nanoparticles

Asystematic study on the surface-enhanced Raman scattering (SERS) for 3,6-bi-2-pyridyl-1,2,4,5-tetrazine (bptz) adsorbed onto citrate-modified gold nanoparticles (cit-AuNps) was carried out based on electronic and vibrational spectroscopy and density functional methods. The citrate/bptz exchange was carefully controlled by the stepwise addition of bptz to the cit-AuNps, inducing flocculation and leading to the rise of a characteristic plasmon coupling band in the visible region. Such stepwise procedure led to a uniform decrease of the citrate SERS signals and to the rise of characteristic peaks of bptz, consistent with surface binding via the N heterocyclic atoms. In contrast, single addition of a large amount of bptz promoted complete aggregation of the nanoparticles, leading to a strong enhancement of the SERS signals. In this case, from the distinct Raman profiles involved, the formation of a new SERS environment became apparent, conjugating the influence of the local hot spots and charge-transfer (CT) effects. The most strongly enhanced vibrations belong to a(1) and b(2) representations, and were interpreted in terms of the electromagnetic and the CT mechanisms: the latter involving significant contribution of vibronic coupling in the system.

Supramolecular Approach to Gold Nanoparticle/Triruthenium Cluster Hybrid Materials and Interfaces

A systematic and comprehensive study of the interaction of citrate-stabilized gold nanoparticles with triruthenium cluster complexes of general formula [Ru(3)(CH(3)COO)(6)(L)](+) [L = 4-cyanopyridine (4-CNpy), 4,4`-bipyridine (4,4`-bpy) or 4,4`-bis(pyridyl)ethylene (bpe)] has been carried out. The cluster-nanoparticle interaction in solution and the construction of thin films of the hybrid materials were investigated in detail by electronic and surface plasmon resonance (SPR) spectroscopy, Raman scattering spectroscopy and scanning electron microscopy (SEM). Citrate-stabilized gold nanoparticles readily interacted with [Ru(3)O(CH(3)COO)(6)(L)(3)](+) complexes to generate functionalized nanoparticles that tend to aggregate according to rates and extents that depend on the bond strength defined by the characteristics of the cluster L ligands following the sequence bpe > 4,4`-bpy >> 4-CNpy. The formation of compact thin films of hybrid AuNP/[Ru(3)O(CH(3)COO)(6)(L)(3)](+) derivatives with L = bpe and 4,4`-bpy indicated that the stability/lability of AuNP-cluster bonds as well as their solubility are important parameters that influence the film contruction process. Fluorine-doped tin oxide electrodes modified with thin films of these nanomaterials exhibited similar electrocatalytic activity but much higher sensitivity than a conventional gold electrode in the oxidation of nitrite ion to nitrate depending on the bridging cluster complex, demonstrating the high potential for the development of amperometric sensors.

Synthesis and characterization of mono and polymeric cyclopalladated compounds: Crystal and molecular structure of [{Pd(dmba)(ONO(2))}(2)(mu-pz)] center dot H(2)O (pz = pyrazine)

In the treatment of cyclometallated dimer [Pd(dmba)(mu-Cl)](2) (dmba = N,N-dimethylbenzylamine) with AgNO(3) and acetonitrile the result was the monomeric cationic precursor [Pd(dmba)(NCMe)(2)](NO(3)) (NCMe=acetonitrile) (1). Compound 1 reacted with m-nitroaniline (m-NAN) and pirazine (pz), originating [Pd(dmba)(ONO(2))(m-NAN)] (2) and [{Pd(dmba)(ONO(2))}(2)(mu-pz)] center dot H(2)O (3), respectively. These compounds were characterized by elemental analysis, IR and NMR spectroscopy. The IR spectra of (2-3) display typical bands of monodentade O-bonded nitrate groups, whereas the NMR data of 3 are consistent with the presence of bridging pyrazine ligands. The structure of compound 3 was determined by Xray diffraction analysis. This packing consists of a supramolecular chain formed by hydrogen bonding between the water molecule and nitrato ligands of two consecutive [Pd(2)(dmba)(2)(ONO(2))2(mu-pz)] units.

The Construction of Identity in Edwidge Danticat's The Farming of Bones

The Farming of Bones deals with issues surrounding the dynamic connections between identity and boundary construction in post-colonial context. It will present an analysis of how the novelist problematizes and communicates her idea of social and national identity construction to her readers and how the readers can identify themselves with the struggles and challenges of the protagonist Amabelle who is trying to find her own identity. This essay will show how Danticat’s novel contributes to an understanding of national identity beyond borders and makes the reader take the role of an individual who constructs her identity by uncovering moments of raw humanness. Until now, no literary scholar has examined the protagonist’s therapeutic role in bridging this social and national gap. Instead critics have discussed other issues of the novel like crossing and re-crossing the border, love, dreams, etc. Although this scholarship has been very effective and rewarding, it lacks any focus on the complexity of the characters’ identity construction. Therefore, this paper will reconsider Danticat’s The Farming of Bones with a closer attention to the question of identity.

'Moving On' and Transitional Bridges : Studies on migration, violence and wellbeing in encounters with Somali-born women and the maternity health care in Sweden

During the latest decade Somali-born women with experiences of long-lasting war followed by migration have increasingly encountered Swedish maternity care, where antenatal care midwives are assigned to ask questions about exposure to violence. The overall aim in this thesis was to gain deeper understanding of Somali-born women’s wellbeing and needs during the parallel transitions of migration to Sweden and childbearing, focusing on maternity healthcare encounters and violence. Data were obtained from medical records (paper I), qualitative interviews with Somali-born women (II, III) and Swedish antenatal care midwives (IV). Descriptive statistics and thematic analysis were used. Compared to pregnancies of Swedish-born women, Somali-born women’s pregnancies demonstrated later booking and less visits to antenatal care, more maternal morbidity but less psychiatric treatment, less medical pain relief during delivery and more emergency caesarean sections and small-for-gestational-age infants (I). Political violence with broken societal structures before migration contributed to up-rootedness, limited healthcare and absent state-based support to women subjected to violence, which reinforced reliance on social networks, own endurance and faith in Somalia (II). After migration, sources of wellbeing were a pragmatic “moving-on” approach including faith and motherhood, combined with social coherence. Lawful rights for women were appreciated but could concurrently risk creating power tensions in partner relationships. Generally, the Somali-born women associated the midwife more with providing medical care than with overall wellbeing or concerns about violence, but new societal resources were parallel incorporated with known resources (III). Midwives strived for woman-centered approaches beyond ethnicity and culture in care encounters, with language, social gaps and divergent views on violence as potential barriers in violence inquiry. Somali-born women’s strength and contentment were highlighted, and ongoing violence seldom encountered according to the midwives experiences (IV). Pragmatism including “moving on” combined with support from family and social networks, indicate capability to cope with violence and migration-related stress. However, this must be balanced against potential unspoken needs at individual level in care encounters.With trustful relationships, optimized interaction and networking with local Somali communities and across professions, the antenatal midwife can have a “bridging-function” in balancing between dual societies and contribute to healthy transitions in the new society.

Double stranded DNA-binding studies of potential Rhodium(ll) antitumor complexes

In 1952, Dwyer and coworkers began testing a series of metal complexes for potential inhibition of cancer cell proliferation in animals.[l] The complexes tested were unsuitable for such studies due to their high toxicity. Therefore, no further work was done on the project. However, in 1965, Rosenberg and coworkers revisited the possibility of potential metal-based drugs. Serendipitously, they discovered that cis-diamminedichloroplatinum(lI) (cisplatin) inhibits cell division in E. coli.[2] Further studies of this and other platinum compounds revealed inhibition of tumor cell lines sarcoma 180 and leukemia LI2l0 in mice.[l] Cisplatin was approved by the Food and Drug Administration in 1970 as a chemical chemotherapeutic agent in the treatment of cancer. The drug has primarily been used in the treatment of testicular and ovarian cancers, although the powerful chemotherapeutic properties of the compound indicate use against a variety of other cancers.[3] The toxicity of this compound, however, warrants the development of other metal-based potential antitumor agents. The success of cisplatin, a transition-metal-based chemotherapeutic, opened the doors to a host of research on the antitumor effects of other transition-metal complexes. Beginning in the 1970s, researchers looked to rhodium for potential use in antitumor complexes. Dirhodium complexes with bridging equatorial ligands (Figure I) were the primary focus for this research. The overwhelming majority of these complexes were dirhodium(II) carboxylate complexes, containing two rhodium(II) centers, four equatorial ligands in a lantero formation around the metal center, and an axial ligand on either end. The family of complexes in Figure 1 will be referred to as dirhodium(II) carboxylate complexes. The dirhodium centers are each d? with a metal-metal bond between them. Although d? atoms are paramagnetic, the two unpaired electrons pair to make the complex diamagnetic. The basic formula of the dirhodium(lI) carboxylate complexes is Rh?(RCOO)?(L)? with R being methyl, ethyl, propyl, or butyl groups and L being water or the solvent in which the complex was crystalized. Of these dirbodium(II) carboxylate complexes, our research focuses on Rb la and two other similar complexes Rh2 and Rh3 (Figure 2). Rh2 is an activated form of Rhla, with four acetonitrile groups in place of two of the bidentate acetate ligands. Rh3 is similar to Rhla, with trifluoromethyl groups in place of the methyl groups on the acetate ligands.

Defeitos pontuais nos compostos intermetálicos ZrNi e Zr/sub 2/Ni estudados por dinâmica molecular

Empregamos a técnica de Dinâmica Molecular para estudar propriedades de defeitos pontuais nos compostos intermetálicos ZrNi e Zr2Ni. Descrevemos as configurações estáveis de defeitos e mecanismos de migração, assim como as energias envolvidas. Os potenciais interatômicos foram derivados do Embedded Atom Model. No intuito de levar em conta a variação de estequiometria causada pela presença de alguns tipos de defeitos em intermetálicos, apresentamos um método numérico que fornece a energia efetiva de formação de defeitos e aplicamos o método ao ZrNi e Zr2Ni. Os resultados mostraram que vacâncias são mais estáveis na sub—rede do Ni, com energia de formação de 0,83 e-0,61 eV em ZrNi e Zr2Ni, respectivamente. Vacâncias de Zr são instáveis em ambos compostos; elas decaem espontaneamente em pares anti—sítio e vacância de Ni. Configurações e energias de formação de intersticiais também foram calculadas e mostraram comportamentos similares. Em ZrNi, a migração de vacâncias ocorre preferencialmente nas direções [025] e [100], com as respectivas energias de migração 0,67 e 0,73 eV, e é um processo essencialmente bidimensional no plano (001). Em Zr,Ni, a migração de vacâncias é unidimensional, ocorrendo na direção [001], com energia de migração de 0,67 eV. Em ambos compostos a presença de defeitos de anti—sítio de Ni diminui a energia de migração da vacância de Ni em até 3 vezes e facilita a movimentação em três dimensões. Mecanismos de anel não são energeticamente eficientes em comparação com saltos diretos. As configurações estáveis de intersticiais em ambos compostos consistem em um átomo de Ni sobre o plano (001) entre dois vizinhos de Zr fora do plano. Intersticiais de Zr são instáveis e tendem a deslocar um átomo de Ni, ocupando seu sítio. Energias de deslocamento foram estudadas através de simulações de irradiação de ambos compostos. Durante o processo de colisão binária, um potencial universal ZBL foi usado para colisões a curta distância. Para distâncias intermediárias usamos um potencial de união arbitrário. Zr mostrou—se mais difícil de ser arrancado de seu sítio do que Ni. Encontramos valores de energia de deslocamento no intervalo de aproximadamente 29 eV até 546 eV. Alguns resultados experimentais são mostrados e apresentam boa concordância com os cálculos.

From legal commons to social commons: Brazil and the cultural industry in the 21st century

This article describes some of the current transformations regarding the processes by which information and culture are generated, from the point of view of developing countries. In this brief analysis, the article discusses the role of projects such as Creative Commons for developing countries. It also discusses the idea of legal commons and social commons. While the idea of legal commons can be understood as the voluntary use of licenses such as Creative Commons in order to create a “commons”, the idea of social commons has to do with the tensions between legality and illegality in developing countries. These tensions appear prominently in the so-called global “peripheries”, and in many instances make the legal structure of intellectual property irrelevant, unfamiliar, or unenforceable, for various reasons. With the emergence of digital technology and the Internet, in many places and regions in developing countries (especially in the “peripheries”), technology ended up arriving earlier than the idea of intellectual property. Such a de facto situation propitiated the emergence of cultural industries that were not driven by intellectual property incentives. In these cultural businesses, the idea of “sharing” and of free dissemination of the content is intrinsic to the social circumstances taking place in these peripheries. Also, the appropriation of technology on the part of the “peripheries” ends up promoting autonomous forms of bridging the digital divide, such as the “LAN house” phenomenon discussed below. This paper proposes that many lessons can be learned from the business models emerging from social commons practices in developing countries. The tension between legality and illegality in “peripheral” areas in developing countries is not new. The work of Boaventura de Sousa Santos and others in the 1970s was paradigmatic for the discussion of legal pluralism regarding the occupation of land in Brazil. This paper aims to follow in that same pioneer tradition of studies about legal pluralism, and to apply those principles to the discussion of “intellectual property” rather than the ownership of land.

Análise da regulação contábil: um ensaio à luz da teoria tridimensional do direito, da teoria normativa da contabilidade e do gerenciamento da informação contábil, numa perspectiva interdisciplinar

The choice of accounting standards capable of defining the recognition, measurement and publicizing of financial and economic information to the general public constitutes one of the accounting community¿s greatest challenges. So, the analysis of the Fundamental Principles of Accounting and of the Conceptual Structure of Accounting becomes relevant because of its direct relation to the normative process and because it represents the essence of doctrines and theories relating to the Science of Accounting. Each country¿s set of rules diverges when it comes to creating and evidencing Accounting Statements, and that¿s why the harmonization of the International Accounting Rules is becoming more important among accountants: as an answer to the world qualitative and quantitative demand for information. When managers, answering a great variety of incentives, manipulate or manage the disclosure of accounting information, they show that the management of accounting information begins to represent a purposeful intervention in the process of elaboration of financial and economic statements with the intention of obtaining some private benefit. In this context, Accounting Regulation performs an important function in the technical procedure of professionals in the area and in the development of practices convergent with international standards, which, in their turn, are already in force. The present study, which is exploratory and non-experimental, aims at presenting and analyzing the process of accounting regulation under the perspective of rules and of the choice of accounting practices as an answer by regulated entities on a tridimensional perspective. The establishment of interaction among diverse fields, through interdisciplinarity, aims at bridging the gap between the fields of law and accounting by articulating concepts and cognitive schemes in a process of mutual enrichment. The research concludes that it is possible to apply concepts from Miguel Reale¿s Tridimensional Theory of Law in the study of accounting regulation.

O papel das relações interpessoais na condução do ProSavana-JBM (Japão-Brasil-Moçambique): um estudo de caso: programa de Cooperação Triangular para o Desenvolvimento Agrícola da Savana Tropical de Moçambique

O objetivo deste estudo de caso foi o de identificar o papel das relações interpessoais na condução do ProSAVANA-JBM (JAPÃO-BRASIL-MOÇAMBIQUE), Programa de Cooperação Triangular para o Desenvolvimento Agrícola da Savana Tropical de Moçambique. Os objetivos intermediários permitem também investigar quais outros fatores podem ter sido determinantes na condução do ProSAVANA. Este programa além de representar uma parceria internacional entre organizações de três países Brasil, Japão e Moçambique, possui impactos de ordem social, econômica e ambiental. A análise dos dados demonstra que as relações interpessoais exerceram a maior centralidade entre os demais fatores determinantes à condução do Programa, e também corrobora para o desenho de um modelo de rede de relações interpessoais relacionada ao ProSAVANA. As limitações do estudo referem-se à dificuldade deste estudo ser replicado ou generalizado cientificamente, considerando que não seria possível emitir avaliações sobre determinado comportamento, a partir de um estudo de caso único. Finalmente, o propósito deste estudo é oferecer instrumentos teóricos e empíricos que permitam aprofundar a reflexão sobre o papel das relações interpessoais, além de contribuir para as lacunas existentes no campo da gestão empresarial e pública.

Teoria científica das empresas e participações societárias estatais - TEPSES: governanças pública, corporativa e o caso do Brasil

RESUMO Ao identificar a existência de lacuna teórica, o presente trabalho definiu como seu objetivo: Estabelecer os alicerces de uma epistéme sobre o fenômeno por meio do desenvolvimento de um arcabouço capaz de a) direcionar e dar sustentação à construção e ao desenvolvimento coletivo de uma Teoria Científica das Empresas e Participações Societárias Estatais – TEPSES, e de b) identificar elementos que viabilizem o desenvolvimento de respostas à questão aplicada central: Como devem os governos definir as missões, os critérios de desempenho e os mecanismos de governança das empresas estatais em um ambiente em mudança? Considerando sua materialidade, a relevância estratégica dessas empresas para os Estados contemporâneos, suas implicações para os processos de globalização e a administração uma ciência aplicada a demandarem nível de análise societal e abordagem multiparadigmática, o arcabouço e seus elementos proporcionaram resposta a várias inquietações e problemas expressos, alguns por mais de meio século, por autoridades no campo como Pritchett, Seidman, Sherwood, Shepherd, Aharoni, Millward, Hinds e Baumol. Oferecendo por redução fenomenológica uma definição de conceito universal para as empresas estatais e introduzindo, inter allia, os conceitos de capacidade essencial de Estado em seu intervalo – CEEi e de estatal patrimonial, que permitiram a construção de uma escala de interesses públicos; o arcabouço teórico focado rueschemeyeriano da TEPSES, constrói pontes entre os hemisférios da grande dicotomia do direito e entre aspectos de governanças pública e corporativa, por meio de tipologias lazarsfeldianas. Em suas seis dimensões iniciais e trinta e três relações o arcabouço foi aplicado por sondagem plausibilística ao caso das estatais diretas brasileiras, apresentando elevado grau de plausibilidade e qualidade, inclusive segundo critérios de Wacker. As formulações e explicitações da TEPSES oferecem respostas e possibilidades de tratamento a várias questões científicas mais amplas como: o paradoxo do conhecimento na regulação de Balleisen, a armadilha de Schneider, a dúvida de Ikeda/Mises e a reabertura da questão de adequação organizacional pelo nobel Simon; proporcionando ainda extensões a: tipologia de estruturas de governança do nobel Williamson, as concepções de sociedade prismática de Riggs, a definição da administração como ciência aplicada do nobel Simon, as formulações institucionalistas de Acemoglu e Robinson e as abordagens sobre intervenção de Estado do nobel Stiglitz. O arcabouço da TEPSES possibilita: a) a cada país, construir sua própria tipologia empírica de empresas estatais e assim geri-las a partir de respostas customizadas à questão aplicada central, analisar sua adequação como instrumento de políticas públicas e desenvolver critérios para suas privatizações; b) a gestores, pesquisadores e estudiosos de caso situar e analisar suas empresas a partir do arcabouço; c) às pesquisas pretéritas, terem seus dados reinterpretados à luz de um novo referencial e d) a todos, a possibilidade de conectarem seus trabalhos à epistéme da qual a TEPSES é alicerce e repositório. Conclui-se que o grau de relevância, em nível global, do fenômeno é na realidade muito superior à sua materialidade e ao grau de relevância atribuído inicialmente, devido à identificação de sua condição como fator empírico de capacidades de Estado, uma vez que à ausência e deficiências dessas capacidades são atribuídos colapsos e débâcles de vários Estados nacionais, que resultaram em elevadíssimos e incalculáveis custos humanos.

Microcrédito emancipatório no nordeste do Brasil? : estudo de caso do Crediamigo Comunidade nos municípios de Caucaia-Ce e Maranguape-Ce

This piece of work consists in a study case of Crediamigo Comunidade, a product from the portfolio of Crediamigo Program of Banco do Nordeste, that uses the methodology of the Comunitary Banks in the concession of low amount loan to poor communities. The main question consists to understand how the Crediamigo Comunidade is characterized faced to the conflict of emancipatory versus liberal paradigms, that exists in the microcredit area. The main objective will analyze how the mechanisms: social capital, empowerment, formation to credit education and better conditions for economic and social issues promoted in the specific objectives of this product, before the dipute between these paradigms. The method adopted analyzed, in a longitudinal perspective, the three years of the product s existence (jun/2005 to jul 2008). Primary and secondary data made possible to identify qualitatively, emancipatory and non emancipatory attributes in the actions and results of Crediamigo Comunidade. It is concluded that the Crediamigo Comunidade works in a liberal logic of the Crediamigo Program, consequently, his focus is not in the emancipation of the poorest clients. The empowerment is individual and not communitary or Freiriano ; the social capital relations enlarges itself in its bounding and bridging ties, but not in its linkage ties, to have access to politic actors and consequently communitary strengthen. All the formation in the Crediamigo is strictly commercial. These characteristics happen by the liberal paradigm in the Crediamigo management and of all of its products, including the Crediamigo Comunidade
