En cualquier empresa el crecimiento supone una dimensión dinámica, en movimiento más o menos continúo, mientras que el tamaño representa una visión estática de la misma. Desde hace algunos años y en particular en el reciente período (2014-2020) de programación de las políticas de apoyo al desarrollo rural, se está interviniendo sobre el sector cooperativo agroalimentario, priorizando y promoviendo procesos de crecimiento atendiendo al criterio del tamaño en particular. En este trabajo de investigación de Tesis Doctoral se ha querido ahondar en esta cuestión desde un enfoque micro. Para ello se analizan, a nivel de cooperativa, las principales fórmulas de crecimiento desarrolladas por cooperativas hortofrutícolas, no con la pretensión de presentarlo como fenómeno global o receta normativa del cooperativismo agroalimentario, sino como especificidades emergentes del crecimiento cooperativo que no están basados únicamente en el tamaño de las empresas, como a menudo se ilustra desde las administraciones; considerando diversas transformaciones y cambios que estas organizaciones deben desarrollar en el proceso dinámico de crecimiento. Para ello se abordan con una especial atención las implicaciones jurídicas en cada caso y, en este marco, se contemplan diversos estudios vinculados con la evolución de la legislación cooperativa en relación a sus formas de crecimiento en el campo agroalimentario. La contextualización del sector y de los procesos de crecimiento se realiza a nivel europeo y español, prestando especial atención al sector hortofrutícola, para lo cual se han tenido como elementos de apoyo y soporte los informes elaborados dentro del proyecto financiado por la Comisión Europea: Support for Farmers cooperatives (Bijman et al, 2012) y las bases de datos disponibles. El proceso metodológico se ha apoyado en diversas técnicas de investigación social para abordar un análisis empírico a nivel micro basado en tres casos seleccionados como paradigmáticos de integración de cooperativas, sobre los que se realizado una encuesta intensa y un análisis con el Ciclo de Vida de una cooperativa alcanzando resultados sobre la diversidad en las formas de integración y la evolución económico-financiera, social y organizacional que los acompañan, todo ello utilizando una perspectiva histórica de al menos nueve ejercicios ulteriores a los procesos de integración. Las tres cooperativas hortofrutícolas objeto de análisis desarrollan su actividad en el Sureste de la Península Ibérica. Con la identificación de aquellos aspectos más relevantes que pueden haber influido en el desarrollo de estos procesos, el análisis arroja resultados de interés que indican que la legislación actual promueve formas de crecimiento de las cooperativas basadas en la dimensión, sin tener en cuenta otros factores manifiestos de heterogeneidad. La apuesta por la especialización de la empresa cooperativa, incluso recurriendo a la limitación de socios, es una forma de crecimiento sostenible en determinados casos. Como también lo es una mayor implicación de los socios y el desarrollo de mecanismos ágiles para responder rápidamente a los incentivos de un mercado cambiante. La sostenibilidad y la mejora de la salud en los procesos de integración deben apoyarse en mecanismos que generen mayor participación e implicación de su masa social en las estructuras de gobierno para evitar la pérdida de capital social. ABSTRACT In any business growth is a dynamic dimension, in more or less continuous movement, while the size represents a static view of it. In recent years and particularly in the recent period (2014-2020) programming policies to support rural development, are being used to intervene on the agrifood cooperative sector, prioritizing and promoting growth processes by the criterion of size in particular. This research work Doctoral Thesis has aimed to delve into this issue from a micro approach. To this are discussed at the level of cooperative, the main growth formulas developed by a sector of horticultural cooperatives, not with the intention of presenting it as a global phenomenon or policy prescription of the food cooperative, but as emerging specificities of the cooperative growth are not based only in the size of companies, as often it is shown from the authorities, but also consider the transformations and changes that these organizations should develop in the dynamic process of growth. For it dealt with special attention the legal implications in each case and, in this context, they have been contemplated several studies linked to the development of cooperative legislation in relation to their growth forms in the food field. The contextualization of the sector and growth processes is performed at European and state level, paying special attention to horticulture, for which they have been taken as support reports the reports prepared within the project funded by the European Commission: Support for Farmers cooperatives (Bijman et al, 2012) and available databases. The methodology has relied on various techniques of social research to address an empirical micro-level analysis based on three cases selected as paradigmatic integration of cooperatives, on which intensive survey and analysis with the Life Cycle of a cooperative made achieving results on the diversity in the forms of integration and economic and financial, social and organizational evolution that accompany them, all using a historical perspective of at least nine subsequent years to the integration processes. The three analyzed horticultural cooperatives are based in the southeast of the Iberian Peninsula. With the identification of the most relevant aspects that may have influenced the development of these processes, the analysis yields interesting results that indicate that the current legislation promotes growth forms of cooperatives based on the dimension regardless of other factors of apparent heterogeneity or socio-cultural barriers. The commitment to specialization of the cooperative enterprise, including through limiting partners is a form of sustainable growth in certain cases. As it is also a greater involvement of partners and the development of efficient mechanisms to respond quickly to changing market incentives. Sustainability and health improvement in growth processes must rely on mechanisms that generate greater participation and involvement of its membership in the structures of government, to avoid the lost of social capital.

A dissertação preocupou-se em analisar as relações de bandidos e ex-bandidos com o pentecostalismo na Assembleia de Deus Fortificada em Cristo (ADFEC), situada na favela Jardim São Jorge, periferia da Cidade Ademar, região Sul da capital de São Paulo. Interessou-nos compreender as interações desses agentes e de qual maneira a igreja desempenhou seu trabalho em um espaço pentecostal. A pesquisa, teve como objetivo fundamental, examinar as aproximações da criminalidade e o pentecostalismo indicando suas rupturas e características peculiares. O trabalho de campo se dedicou em coletar dados que comprovassem atuação da ADFEC juntos aos agentes do crime, e em que medida a filiação religiosa dos agentes ganhava importância. Por fim, buscamos refletir sobre a adesão de bandidos e ex-bandidos ao pentecostalismo e a influência dessa adesão no cotidiano da comunidade.

As ações de maior liquidez do índice IBOVESPA, refletem o comportamento das ações de um modo geral, bem como a relação das variáveis macroeconômicas em seu comportamento e estão entre as mais negociadas no mercado de capitais brasileiro. Desta forma, pode-se entender que há reflexos de fatores que impactam as empresas de maior liquidez que definem o comportamento das variáveis macroeconômicas e que o inverso também é uma verdade, oscilações nos fatores macroeconômicos também afetam as ações de maior liquidez, como IPCA, PIB, SELIC e Taxa de Câmbio. O estudo propõe uma análise da relação existente entre variáveis macroeconômicas e o comportamento das ações de maior liquidez do índice IBOVESPA, corroborando com estudos que buscam entender a influência de fatores macroeconômicos sobre o preço de ações e contribuindo empiricamente com a formação de portfólios de investimento. O trabalho abrangeu o período de 2008 a 2014. Os resultados concluíram que a formação de carteiras, visando a proteção do capital investido, deve conter ativos com correlação negativa em relação às variáveis estudadas, o que torna possível a composição de uma carteira com risco reduzido.

O contexto batista é predominantemente marcado por lideranças masculinas, destinando às mulheres apenas lugares e comportamentos socialmente estabelecidos, como a casa, o cuidado, a maternidade, a submissão, entre outras características que enfatizam a hierarquia de gênero. Mesmo diante do desenvolvimento econômico e da ocupação que as mulheres estão conquistando no campo público, a igreja e principalmente as igrejas batistas, permanecem fundadas em alicerces que exaltam o poder masculino em detrimento do lugar que deve ser ocupado pelas mulheres, ou seja, onde elas decidirem atuar. Caso elas decidam atuar num campo predominantemente masculino, terão que lidar com a desconstrução de um pensamento socialmente permeado de dominação masculina e com a árdua construção de um pensamento que vise a igualdade de gênero. O objeto desta pesquisa é o ministério pastoral feminino no contexto batista brasileiro. O texto analisa o discurso das Pastoras Batistas do Estado de São Paulo e o discurso dos líderes da Ordem dos Pastores Batistas de São Paulo (OPBB-SP) a respeito do ministério pastoral feminino e a não filiação de mulheres na OPBB-SP. A importância deste trabalho é a de demostrar as relações de micro poder existentes entre pastores e pastoras e concomitantemente as desigualdades dentro do contexto batista com relação ao ministério pastoral feminino. Essa afirmação se consolida por meio das análises das entrevistas semiestruturadas que realizei na pesquisa de campo, com sete pastoras batistas do Estado de São Paulo, bem como com três líderes da OPPB-SP. Esta é uma pesquisa qualitativa, em que foram analisados documentos oficiais da igreja, como pautas de convenções, atas, sites institucionais, periódicos e documentos não oficiais encontrados em redes sociais, blogs, jornais online, entre outros. Posso afirmar que as pastoras batistas estão se mobilizando para cumprir sua vocação, usando argumentos transcendentes que impedem qualquer pessoa de desafiar ou duvidar de seu chamado pastoral, pois: “O vento sopra onde quer; ouve-se o ruído, mas não sabes de onde vem, nem para onde vai. Assim acontece com aquele(a) que nasceu do Espírito.” (João 3.8).

The objectives of this and the following paper are to identify commonalities and disparities of the extended environment of mononuclear metal sites centering on Cu, Fe, Mn, and Zn. The extended environment of a metal site within a protein embodies at least three layers: the metal core, the ligand group, and the second shell, which is defined here to consist of all residues distant less than 3.5 Å from some ligand of the metal core. The ligands and second-shell residues can be characterized in terms of polarity, hydrophobicity, secondary structures, solvent accessibility, hydrogen-bonding interactions, and membership in statistically significant residue clusters of different kinds. Findings include the following: (i) Both histidine ligands of type I copper ions exclusively attach the Nδ1 nitrogen of the histidine imidazole ring to the metal, whereas histidine ligands for all mononuclear iron ions and nearly all type II copper ions are ligated via the Nɛ2 nitrogen. By contrast, multinuclear copper centers are coordinated predominantly by histidine Nɛ2, whereas diiron histidine contacts are predominantly Nδ1. Explanations in terms of steric differences between Nδ1 and Nɛ2 are considered. (ii) Except for blue copper (type I), the second-shell composition favors polar residues. (iii) For blue copper, the second shell generally contains multiple methionine residues, which are elements of a statistically significant histidine–cysteine–methionine cluster. Almost half of the second shell of blue copper consists of solvent-accessible residues, putatively facilitating electron transfer. (iv) Mononuclear copper atoms are never found with acidic carboxylate ligands, whereas single Mn2+ ion ligands are predominantly acidic and the second shell tends to be mostly buried. (v) The extended environment of mononuclear Fe sites often is associated with histidine–tyrosine or histidine–acidic clusters.

A comparison was made of the competence for neoplastic transformation in three different sublines of NIH 3T3 cells and multiple clonal derivatives of each. Over 90% of the neoplastic foci produced by an uncloned transformed (t-SA′) subline on a confluent background of nontransformed cells were of the dense, multilayered type, but about half of the t-SA′ clones produced only light foci in assays without background. This asymmetry apparently arose from the failure of the light focus formers to register on a background of nontransformed cells. Comparison was made of the capacity for confluence-mediated transformation between uncloned parental cultures and their clonal derivatives by using two nontransformed sublines, one of which was highly sensitive and the other relatively refractory to confluence-mediated transformation. Transformation was more frequent in the clones than in the uncloned parental cultures for both sublines. This was dramatically so in the refractory subline, where the uncloned culture showed no overt sign of transformation in serially repeated assays but increasing numbers of its clones exhibited progressive transformation. The reason for the greater susceptibility of the pure clones is apparently the suppression of transformation among the diverse membership that makes up the uncloned parental culture. Progressive selection toward increasing degrees of transformation in confluent cultures plays a major role in the development of dense focus formers, but direct induction by the constraint of confluence may contribute by heritably damaging cells. In view of our finding of increased susceptibility to transformation in clonal versus uncloned populations, expansion of some clones at the expense of others during the aging process would contribute to the marked increase of cancer with age.

In the last decade, two tools, one drawn from information theory and the other from artificial neural networks, have proven particularly useful in many different areas of sequence analysis. The work presented herein indicates that these two approaches can be joined in a general fashion to produce a very powerful search engine that is capable of locating members of a given nucleic acid sequence family in either local or global sequence searches. This program can, in turn, be queried for its definition of the motif under investigation, ranking each base in context for its contribution to membership in the motif family. In principle, the method used can be applied to any binding motif, including both DNA and RNA sequence families, given sufficient family size.
