Hybrid materials for biomedical applications

The increased longevity of humans and the demand for a better quality of life have led to a continuous search for new implant materials. Scientific development coupled with a growing multidisciplinarity between materials science and life sciences has given rise to new approaches such as regenerative medicine and tissue engineering. The search for a material with mechanical properties close to those of human bone produced a new family of hybrid materials that take advantage of the synergy between inorganic silica (SiO4) domains, based on sol-gel bioactive glass compositions, and organic polydimethylsiloxane, PDMS ((CH3)2.SiO2)n, domains. Several studies have shown that hybrid materials based on the system PDMS-SiO2 constitute a promising group of biomaterials with several potential applications from bone tissue regeneration to brain tissue recovery, passing by bioactive coatings and drug delivery systems. The objective of the present work was to prepare hybrid materials for biomedical applications based on the PDMS-SiO2 system and to achieve a better understanding of the relationship among the sol-gel processing conditions, the chemical structures, the microstructure and the macroscopic properties. For that, different characterization techniques were used: Fourier transform infrared spectrometry, liquid and solid state nuclear magnetic resonance techniques, X-ray diffraction, small-angle X-ray scattering, smallangle neutron scattering, surface area analysis by Brunauer–Emmett–Teller method, scanning electron microscopy and transmission electron microscopy. Surface roughness and wettability were analyzed by 3D optical profilometry and by contact angle measurements respectively. Bioactivity was evaluated in vitro by immersion of the materials in Kokubos’s simulated body fluid and posterior surface analysis by different techniques as well as supernatant liquid analysis by inductively coupled plasma spectroscopy. Biocompatibility was assessed using MG63 osteoblastic cells. PDMS-SiO2-CaO materials were first prepared using nitrate as a calcium source. To avoid the presence of nitrate residues in the final product due to its potential toxicity, a heat-treatment step (above 400 °C) is required. In order to enhance the thermal stability of the materials subjected to high temperatures titanium was added to the hybrid system, and a material containing calcium, with no traces of nitrate and the preservation of a significant amount of methyl groups was successfully obtained. The difficulty in eliminating all nitrates from bulk PDMS-SiO2-CaO samples obtained by sol-gel synthesis and subsequent heat-treatment created a new goal which was the search for alternative sources of calcium. New calcium sources were evaluated in order to substitute the nitrate and calcium acetate was chosen due to its good solubility in water. Preparation solgel protocols were tested and homogeneous monolithic samples were obtained. Besides their ability to improve the bioactivity, titanium and zirconium influence the structural and microstructural features of the SiO2-TiO2 and SiO2-ZrO2 binary systems, and also of the PDMS-TiO2 and PDMS-ZrO2 systems. Detailed studies with different sol-gel conditions allowed the understanding of the roles of titanium and zirconium as additives in the PDMS-SiO2 system. It was concluded that titanium and zirconium influence the kinetics of the sol-gel process due to their different alkoxide reactivity leading to hybrid xerogels with dissimilar characteristics and morphologies. Titanium isopropoxide, less reactive than zirconium propoxide, was chosen as source of titanium, used as an additive to the system PDMS-SiO2-CaO. Two different sol-gel preparation routes were followed, using the same base composition and calcium acetate as calcium source. Different microstructures with high hydrophobicit were obtained and both proved to be biocompatible after tested with MG63 osteoblastic cells. Finally, the role of strontium (typically known in bioglasses to promote bone formation and reduce bone resorption) was studied in the PDMS-SiO2-CaOTiO2 hybrid system. A biocompatible material, tested with MG63 osteoblastic cells, was obtained with the ability to release strontium within the values reported as suitable for bone tissue regeneration.

The interpersonal and mental health implications of the coherence of coming out narratives for a sample of gay men in committed romantic relationships

The coming out process has been conceptualized as a developmental imperative for those who will eventually accept their same-sex attractions. It is widely accepted that homophobia, heterosexism, and homonegativity are cultural realities that may complicate this developmental process for gay men. The current study views coming out as an extra-developmental life task that is at best a stressful event, and at worst traumatic when coming out results in the rupture of salient relationships with parents, siblings, and/or close friends. To date, the minority stress model (Meyer, 1995; 2003) has been utilized as an organizing framework for how to empirically examine external stressors and mental health disparities for lesbians, gay men, and bisexual individuals in the United States. The current study builds on this literature by focusing on the influence of how gay men make sense of and represent the coming out process in a semi-structured interview, more specifically, by examining the legacy of the coming out process on indicators of wellness. In a two-part process, this study first employs the framework well articulated in the adult attachment literature of coherence of narratives to explore both variation and implications of the coming out experience for a sample of gay men (n = 60) in romantic relationships (n = 30). In particular, this study employed constructs identified in the adult attachment literature, namely Preoccupied and Dismissing current state of mind, to code a Coming Out Interview (COI). In the present study current state of mind refers to the degree of coherent discourse produced about coming out experiences as relayed during the COI. Multilevel analyses tested the extent to which these COI dimensions, as revealed through an analysis of coming out narratives in the COI, were associated with relationship quality, including self-reported satisfaction and observed emotional tone in a standard laboratory interaction task and self-reported symptoms of psychopathology. In addition, multilevel analyses also assessed the Acceptance by primary relationship figures at the time of disclosure, as well as the degree of Outness at the time of the study. Results revealed that participant’s narratives on the COI varied with regard to Preoccupied and Dismissing current state of mind, suggesting that the AAI coding system provides a viable organizing framework for extracting meaning from coming out narratives as related to attachment relevant constructs. Multilevel modeling revealed construct validity of the attachment dimensions assessed via the COI; attachment (i.e., Preoccupied and Dismissing current state of mind) as assessed via the Adult Attachment Interview (AAI) was significantly correlated with the corresponding COI variables. These finding suggest both methodological and conceptual convergence between these two measures. However, with one exception, COI Preoccupied and Dismissing current state of mind did not predict relationship outcomes or self-reported internalizing and externalizing symptoms. However, further analyses revealed that the degree to which one is out to others moderated the relationship between COI Preoccupied and internalizing. Specifically, for those who were less out to others, there was a significant and positive relationship between Preoccupied current state of mind towards coming out and internalizing symptoms. In addition, the degree of perceived acceptance of sexual orientation by salient relationship figures at the time of disclosure emerged as a predictor of mental health. In particular, Acceptance was significantly negatively related to internalizing symptoms. Overall, the results offer preliminary support that gay men’s narratives do reflect variation as assessed by attachment dimensions and highlights the role of Acceptance by salient relationship figures at the time of disclosure. Still, for the most part, current state of mind towards coming out in this study was not associated with relationship quality and self-reported indicators of mental health. This finding may be a function of low statistical power given the modest sample size. However, the relationship between Preoccupied current state of mind and mental health (i.e., internalizing) appears to depend on degree of Outness. In addition, the response of primary relationships figures to coming out may be a relevant factor in shaping mental health outcomes for gay men. Limitations and suggestions for future research and clinical intervention are offered.

Uma vida de relações falhadas: continuidade ou mudança?: estudo sobre a herança psíquica e os desamores narcísicos na vida adulta

Este estudo propôs-se investigar, como os Esquemas Iniciais Desadaptativos (EIDs) concebidos pelo indivíduo e a sua representação dos Estilos Parentais (EPs), influenciam na escolha amorosa da vida adulta considerando os relacionamentos amorosos de reparação narcísica: Submisso-Idealizador, Eufórico-Idealizante e Evitante-Desnarcisante. A amostra constituiu-se por 225 (jovens) adultos/as portugueses/as, entre os 23 e 63 anos, que tivessem tido ou possuíssem na altura do estudo uma relação amorosa. A investigação de natureza quantitativa utilizou como instrumentos o: Inventário de Tipos de Relacionamento Amoroso (ITRA), Questionário de Esquemas (QE) e Questionário de Estilos Parentais (QEP). Segundo os resultados, evidenciou-se a associação de EIDs0F 1 e EPs1F 2 mais precoces e rígidos (incondicionais) aos três tipos de relacionamento amoroso, verificou-se uma herança psíquica trans-geracional com conteúdos individuais e relacionais mantidos e apurou-se a necessidade de o sujeito procurar relações fornecedoras de uma imagem mais completa do seu self desestruturado, concluindo-se que houve uma continuidade de relações falhadas; Abstract: A lifetime of failed relationships: continuity or change? Study about the psychic heritage and narcissistic unlove in adulthood. This study proposes to investigate, how the Early Maladaptive Schemas (EIDs) conceived by the individual and, their representation about the Parental Styles (EPs), influence the choice of adulthood loving relationships considering the romantic relationships of narcissistic repair: Submissive-Idealizer, Euphoric-Idealizing and Avoidant-Devaluate. The sample consisted of 225 Portuguese (young) adults, between 23 and 63 years old, who have had or maintained at the time of the study a loving relationship. The quantitative research used as instruments the: Inventory Types of Loving Relationship (ITRA), Schema Questionnaire (QE) and Parental Styles Questionnaire (QEP). According to the results, it showed the association of more early and rigid (unconditional) EIDs2F 3 and EPs3F 4 with the three types of love relationship, it was found a trans-generational psychic inheritance with individual and relational content maintained and found out the need for the subject pursuit for supplier relations of a more complete image of your self unstructured, concluding that there was a continuity of failed relationships.

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

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

Relações interorganizacionais e confiança no setor da carcinicultura: um estudo de caso na camanor produtos marinhos

This study investigated how the types of confidence based on competence and good will act in the formation and maintenance of cooperation relationships between the Camanor and its partners (Aquatec, Purina, Caçuá, Uvifrios and Malta / Cleyton). It used organizational approaches on networks based primarily on studies of Powell (1987, 1990), Das and Teng (2000, 2001), Child (2001) and Contractor and Lorange (2004) which have described the advantages that cooperative relationships can provide, as well as their limits as alternative governance structures. Confidence has been considered an important factor affecting the actions and development of organizations involved in networks or in strategic alliances (ZAHEER; HARRIS, 2006) and is the most appropriate control mechanism in these situations (SYDOW, 1998). Confidence is seen from two different approaches: the economic and the sociological (ZAHEER; HARRIS, 2006). To facilitate the understanding of confidence some typologies have been created, as proposed by Barney and Hansen (1994), Lane (1998), Das and Teng (2000), Child (2001) and Wever, Martens and Vandenbempt (2005). This study made use of the case study as proposition of Yin (2005). Semi-structured interviews were held with pre-determined routes, in a single stage performed in early 2008. The research subjects were owners and / or responsible for Camanor and its business partners (Aquatec, Purina, Caçuá, Uvifrios and Malta / Cleyton). Also secondary data were collected in several sites related to the industry and enterprises studied, in addition to data collected by previous studies conducted by CARCINEREDES (2006). The primary data were analyzed using the analysing technique of the content proposed by Bardin (1994). Regarding the secondary data, they were qualitatively analyzed according to documentary analysis technique (BARDIN, 1994). Thus, through the data collected, could be concluded that although there is confidence based on good faith in relationships(UZZI, 1998; OF; TENG, 2001), their presence does not determine the formation and / or maintenance of a partnership, serves only in order to facilitate the relationship, making them more flexible. The confidence based on competence (DAS; TENG, 2001) influenced the formation and maintenance of relations studied. Because whether or not to form a relationship with another organization it is used the perception of the partner acts, namely the reputation (image) as decision basis. And it is through the verification of the performance of the partner activities that will determine the continuation of the partnership

As relações da tríplice hélice no setor da carcinicultura do Rio Grande do Norte: uma análise a partir das abordagens da imersão social e da dependência de recursos

This work consists in a study of the Shrimp Industry in the state of Rio Grande do Norte, whose central issue relates to the understanding of how the Triple Helix (University, Government and the productive sector) interrelationship limits or expands the industry s innovation process. The study aims to understand how the Triple Helix relationship interferes in the innovation process of shrimp in Rio Grande do Norte. As the knowledge becomes the resource key for production methods, the generation of new technologies, new products and processes which demands joint and integrated action of the institutions comprising the Triple Helix: University, Government and productive sector, which possess the essential resources to innovate the process and can be maximized from cooperative relationships between the referred Institutions. Thus, in this work, it was sharply used the pioneering studies of Sabato and Botana (1968) regarding the cooperation relationship between the scientific-technological sphere, the governmental and the productive base, and studies on the Triple Helix approach, proposed by Etzkowitz and Leydesdorff (2000), in which the university has a key role in the process of technological and innovative development of countries and regions, and under which it is assigned to the very University - the character of the entrepreneurial institution, through the concept of entrepreneurial University. Aiming to overcome the criticism of Cooke (2005), regarding the limitations of the Triple Helix approach, in this study it was used - as analytical perspectives - the perspective of social immersion (Granovetter, 1985, 2005) and the theory of resources dependence (PFEFFER; SALANCIK, 1978). The analytical perspectives presented in here, despite of the different assumptions, are essential to eliminate the bias that one only approach can lead (ASTLEY; VAN DE VEM; 2007). The authors arguments focus on the fact that the integration is possible if the researcher acknowledged that different perspectives may have different descriptions of the same phenomenon. As a research strategy, this study is characterized as a study case, along with the proposed objectives - the qualitative method was used as an approach and, depending on the gathering of the sector s historical, a sectional longitudinal view approach was applied (VIEIRA, 2004). The primary and secondary data were used in order to understand the sector s evolutionary process and its inter-institutional relations - regarding the shrimp culture in Rio Grande do Norte - to promote the development, as the content was used for the technical analysis (BARDIN, 1977). The approach of social immersion and resources addiction dependence made it possible to understand that relationships are established within and between each sphere (university, government and productive sector) characterizing a network of low density relationships and strongly internal and external dependence. Based on the speech of Etzkowitz and Mello (2006), a successful Triple Helix strategy of innovation requires not only the involvement and commitment of the parts, within the institutional sphere and among them, but also the development of mechanisms to coordinate the multiple and complex interactions and interfaces, focusing on promoting both environment and context for innovation and learning; it can be acknowledge from study results that the shrimp in the State of the RN, although there are several institutional mechanisms to promote greater integration and technological development, has been presented disjointed - both internally and between the spheres - and under no legitimate practice when facing the innovational promotion and integration institutions. Due to those factors, the central institutions of the network are crucial to the promotion of innovations, spreading through their direct contacts the importance factor of the sustainable competitive activity in the world market and on the national level. However, it may be concluded, from the data, that the Triple Helix relations are interfering in a negative way on what concerns the promotion of innovations in the shrimp industry in RN

Ciríaco de Cardoso e O burro do Sr. Alcaide : percursos de formação de um compositor de comédia musical no Portugal finissecular

O principal objetivo deste estudo foi compreender as etapas do percurso artístico do compositor portuense Ciríaco de Cardoso (1846 – 1900) e os discursos em torno de uma das suas obras mais célebres: O burro do Sr. Alcaide (1891). No primeiro capítulo procurou-se identificar e discutir os critérios que estiveram na base das opções profissionais tomadas por Ciríaco. O decurso da sua carreira leva a crer que possuía uma noção profunda das atividades que, no espaço lusófono, apresentavam maior potencial de aquisição quer de capital económico, quer de capital simbólico. É por isso que, mobilizando recursos das suas redes de sociabilidade, circula por instituições no Porto e em Lisboa mas, também, pelo lucrativo mercado teatral do Rio de Janeiro, assim como em Paris. Concentra-se no popular teatro musical – principal fonte de sustento – em paralelo com a atividade concertística e operática – forma de distinção atendendo à competitividade no mercado musico-teatral. Percebe também que a maximização do seu poder simbólico depende da legitimação alcançada pela sua associação às elites socioculturais locais, pelo que fomenta o estabelecimento de sociabilidades que se estendem inclusive às casas reais portuguesa e brasileira. Paradoxalmente, as edes mais próximas de Ciríaco estavam vinculadas a um idealismo republicano, relacionamento que exponencial proliferação de discursos dessa índole pelos media lusófonos (sobretudo a partir do tricentenário camoniano de 1880) e, por outro, pela aparente inexistência de registos que associem inequivocamente o artista ao ativismo republicano. Não obstante, é provável que Ciríaco de Cardoso tenha explorado o filão antimonárquico na programação da temporada de 1891 do Teatro da Avenida. O segundo capítulo explora a produção de O burro do Sr. Alcaide, através da análise da sua estrutura e das relações da obra com a realidade portuguesa da última década do século XIX. Embora respeite o modelo da opereta francesa, apresenta também características que poderão levar a que seja interpretada como transmissora de uma portugalidade idealizada, em linha com o nacionalismo português do último quartel do século. A ação decorre em Lisboa, cenário de interação entre personagens-tipo e caricaturas de personalidades concretas da elite sociopolítica portuguesa. Através de referências ao sebastianismo, satiriza-se o comportamento dessas elites, assim como as instituições da monarquia constitucional e a prevalência de uma visão messiânica dos governantes por parte da sociedade em geral. Faz-se a apologia da ruralidade através de tópicos musicais e de quadros onde se constrói uma imagem da música tradicional, correspondendo a uma idealização da nação – notada e enfatizada na receção pela crítica. Utiliza também outros tópicos pertencentes à paisagem sonora do público burguês, completando a expressão da urbanidade de um país onde essas duas realidades não eram ainda completamente dissociáveis. Contudo, ao não propor alterações efetivas à hierarquia da sociedade portuguesa finissecular, o desfecho da obra leva a concluir que esta terá consistido numa forma de propaganda o que, por um lado, explica o seu mediatismo e, por outro, vincula os seus autores – mais ou menos conscientes disso – às lutas políticas em curso aquando do ano da sua estreia.

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

Abordagem multimetodológica do impacto da mentoria e relações de ajuda no processo informal de employee branding: o efeito de marca de empregado

O processo de employee branding tem demonstrado promover e reforçar o contrato psicológico entre os colaboradores e a organização, pelo incremento e potenciação do sentimento de comprometimento e lealdade do colaborador de acordo com Miles e Mangold. Esta investigação foca-se no estudo do impacto da mentoria e relações de ajuda no processo de employee branding, numa visão integrada da gestão de recursos humanos e do comportamento organizacional, com base nas relações de troca do marketing do relacionamento numa perspetiva da gestão por competências e foco nas Pessoas. Com a introdução da nova variável (mentoria e relações de ajuda) esta investigação, ao enriquecer e incrementar o processo de employee branding de Miles e Mangold proposto em 2004 e 2005, apresenta a construção de um instrumento de diagnóstico do inovador processo de Efeito de Marca de Empregado. A investigação decorreu em 30 organizações, com um total de 725 questionários, que permitiu a validação e fiabilidade do instrumento, bem como demonstra através de métodos estatísticos a influência das ações de mentoria e relações de ajuda e da atuação das relações interpessoais que promovem o processo employee branding. Se o processo de employee branding já incrementava os resultados organizacionais, com esta investigação, pode-se afirmar que o processo de Efeito de Marca de Empregado não só incrementa como também impulsiona a imagem de marca da organização pela atuação dinâmica e catalisadora das relações interpessoais dos seus colaboradores, dentro e fora da organização, com a introdução e promoção de ações mentoria e relações de ajuda entre chefias e chefiados; ABSTRACT: The employee branding process has shown as to promote and strengthen the psychological contract between employees and the organization, by increasing and maximizing the sense of employees’ commitment and loyalty, according with Miles and Mangold. This research focuses on the impact of mentoring and helping relationships in the employee branding process, in an integrated view of human resources management and organizational behavior, based on the exchange ratio of the relationship marketing in a perspective of management by competencies and people focused approach. With the introduction of the new variable (mentoring and helping relationships), this research enriches and enhances the Miles and Mangold employee branding process proposed in 2004 and 2005 and presents the construction of an diagnostic instrument for the innovative process of Employee Brand Effect. This research took place in 30 organizations with a total of 725 questionnaires, which allowed the validation and reliability of the instrument and the evidence through statistical methods of the influence of mentoring and helping relationships actions and of the interaction of interpersonal relationships promoting the employee branding process. If the employee branding process was already boosting organizational results with this research, it can be stated that the Employee Brand Effect process not only increases, but also boosts the organization’s brand image by the actuation of the dynamics of employees’ interpersonal relationships, inside and outside the organization, with the introduction and promotion of mentoring and helping relationships actions between leaders and followers.

Gênero e relações de poder no Pentecostalismo: estudo comparativo entre a Igreja de Cristo no Brasil e a Comunidade Evangélica Sara Nossa Terra

Based on the empirical comparative study between two churches from Pentecostal guidance - both located in Parnamirim/RN - and supported on a dialogic interaction between my interlocutors and theoretical references, I proposed me to reflect about how this protestant segment represents and articulates questions such as gender and power relationships, and the daily impact of that in their followers life. In other words, this dissertation aims to understand the reason of the asymmetry attributed to male and female, especially in what concerns the distribution of ecclesiastic works and the authority given to male, as well as the implication of this reality in the reconfiguration of morality and religious praxis in daily life of individuals and involved groups. From this perspective, this work was divided in three chapters, in which I investigate the tension/relationship between faith and secularism, for from this question on concessions and/or prohibitions related to the limits and involvement of the followers with the world and with the very Pentecostal ethos arise. I also analyze here aspects concerning to both ecclesiastic hierarchy and power, with the objective of elucidating how it occurs, what kind of criteria and implications they consider as well as about the nature of the religious labor division between men and women and, finally, I try to understand how the conversion/adhesion of members is reflected in the redefinitions of gender and its relationship between the ecclesiastical and domestic spaces. The diligence and energy spent in this work is in the hope that its fruits can corroborate in the expansion of anthropological knowledge which, in this particular case, involves the Brazilian Pentecostal phenomenon

Uma cidade para pessoas: funcionalidade, racionalidade e emotividade nas relações mobiliário urbano, espaço público e cidadãos

This research investigates how functionality, rationality, and emotionality applied to urban furniture design contribute to the organization, legibility, and qualification of public spaces, according to different layouts, physical and visual qualities of the urban furniture as well as the quality of urban infrastructure that may influence the uses and appropriation of urban spaces by pedestrians, turning those spaces into socially centripetal or centrifugal places. The work consists of two parts. First refers to a bibliographical review concerning two main issues of the investigation: product design and legibility of public space, defining the conceptual and theoretical bases, linked to methodological strategies aimed at systemic planning and integrated management of urban furniture design and legibility of public spaces (sidewalks), that are necessary to define the existing relationships among the user s interface (pedestrians); product (urban artifacts); built environment (sidewalks). The second part refers to the achievement of empirical approach throughout visual analysis of public spaces and the functional and qualitative evaluation of the existing urban furniture in the central neighborhood of Cidade Alta, Natal, RN, according to the theoretical researched concepts and methodological procedures. The results expose the weaknesses and levels of intensity arising from the relations among public space, urban furniture, and users, revealing the need for theoretical and practical approaches which would help the decision-making in planning, designing and integrating innovative, sustainable, and ethical solutions in order to design attractive public spaces that could provide sociability and citizenship throughout integrated public management, city systemic thinking and urban identity. The suggested guidelines at the end of this research will provide the necessary strategies to design suitable urban furniture systems according to aesthetic and practical urban infrastructure and city context, aiming to ease visual and physical conflicts that may negatively interfere with the appropriation of public spaces by the citizens

A pesca do bacalhau durante o período do Estado Novo (1933-1974) : contributo para as relações interculturais

A presente dissertação tem como objeto de estudo a pesca do bacalhau feita por portugueses sob a bandeira de Portugal durante o período do Estado Novo (1933-1974). Investigou-se as razões para um investimento e um protecionismo tão forte à indústria da pesca do bacalhau. É indissociável do estudo da demanda portuguesa por este peixe, à época muito abundante no noroeste atlântico, as políticas autárcicas e de subsistência pilares da economia do Estado Novo, assim como a implantação e robustecimento da Instituição Corporativa. Subjacente a estas linhas de matriz económica mas paradigmáticas do novo regime, estava também a reconstrução da identidade portuguesa, a sacralização do trabalho e a heroicidade do pescador português do bacalhau. A existência da tentativa de revivificação da glória dos descobrimentos na pesca do bacalhau. A criação de um ambiente social, político e religioso que levaram à persecução destas políticas e consequentemente do engrandecimento da estrutura do Estado Novo, resultando até na sedimentação de apoio popular. O desenvolvimento da frota de pesca longínqua foi quase uma única janela de oportunidades para o conhecimento de novos mundos. A montante e a jusante da atividade piscatória também se desenvolveram indústrias e comércio internacional. A participação em organizações internacionais de regulação das pescas proporcionou contatos Institucionais com outras nações, não raro utilizados para quebrar isolamentos e propagandear o Estado Novo e as suas manifestações culturais e identitárias que suscitaram relacionamentos interculturais. Para além destes contatos mais formais, também se desenvolveram contatos informais, que se repercutiram na criação e manifestação de conhecimento mútuo e claro de condições para a gestação da interculturidade. Estes desenvolvimentos de relações informais, de contatos profissionais também geraram relações culturais que se manifestaram em projetos individuais de vida associados às migrações.
