Cultura, Comunicação e cidadania: o caso do Centro Cultural do Banco do Brasil de São Paulo

O artigo analisa as atuais políticas culturais e analisa empiricamente as ações da unidade paulistana do Centro Cultural Banco do Brasil (CCBB). O objetivo é interpretar como esta instituição opera o fomento à cultura no contexto da normatização cultural no Brasil. A articulação institucional entre Banco do Brasil e seu Centro Cultural enseja algumas particularidades no campo da difusão cultural, pois o status institucional do CCBB condiciona de maneira decisiva as formas como transcorrem as relações com produtores culturais, público consumidor e com seu respectivo mantenedor. Trata-se de estudo baseado em pesquisa bibliográfica, levantamento de campo e na abordagem dialética de análise. Conclui-se que, ao consentir um laissez-faire cultural, o Estado admite que o mercado imponha sua lógica à cultura, de modo que o objeto empírico pode ser caracterizado como um exemplo dessa dinâmica.

Banco de sementes de plantas daninhas e sua correlação com a flora estabelecida no agroecossistema cana-crua

O conhecimento da composição específica do banco de sementes de plantas daninhas e a sua correlação com a flora estabelecida são importantes para nortear o manejo a ser adotado e a escolha dos herbicidas. A colheita mecanizada de cana-de-açúcar acarretou mudanças significativas na composição da flora infestante, quando proporcionou a manutenção de uma camada de palha, reduziu a movimentação do solo e dispensou a prática da queimada. Foram realizados levantamentos do banco de sementes e da flora de plantas daninhas que se estabeleceu em 28 talhões colhidos mecanicamente, sem queima prévia da palha. Com base nos dados de banco de sementes, efetuaram-se estudos fitossociológicos e de correlação entre a composição do banco de sementes e a flora emergida. As principais espécies presentes no banco de sementes foram as pertencentes à classe das dicotiledôneas anuais, com destaque para Amaranthus spp. e diversas espécies de Euphorbiaceae e Convolvulaceae. As sementes de gramíneas tradicionais da cultura tiveram pouca participação. O banco de sementes apresentou correlação não-significativa com a flora emergente, independentemente da época de colheita do talhão, da metodologia de quantificação do banco de sementes e das espécies de plantas daninhas.

O Trabalho e o labirinto da responsabilidade socioempresarial:a experiência da cidadania empresarial do Banco do Brasil

In the current systemic crisis, economic policy is directed to correct the consequences of the functioning of this metabolism, but within the limits of the capital. From this perspective, decision makers propose trade policies, agricultural and industrial to ensure conditions for economic growth. However, as a dead end, there is failure of the State in giving efficacy to the operation of all segments of the economy, especially given the budget constraint. Public managers are forced to seek external resources, resuming the cycle of political allegiance to the interests of international financial and banking representatives, installed in so-called multilateral. The complex ideological capital comes into play in trying to convince society that the paths taken by governments are inevitable, and that capitalism can be "humanized", even with the realization of the growing inequalities caused by historical irrationalism of the production process of capital . In this sense, emerging concepts that attempt to demonstrate the compatibility of the system to real human needs. This ideological offensive is intended to legitimize the capital. The so-called third sector has a special highlight with the concept of corporate social responsibility. It creates a political environment in which the inevitable mix-up with new illusions offered by and often funding the metabolism of capital in order to perpetuate this system. In this context, political elites, and considerable portions of the academy, embark on "waves of capitalist optimism," while the sociometabolismo capital expands its historical limits, driving forces postponing their collapse, but that cause human suffering and ecological stress. Wars are disseminated to strengthen the deadly war industry and the automobile industry; and devastating the environment of which depends the capital system. In this scenario disassemble, propositions emerge around a "new social pact" in order to minimize the adverse effects of the dynamics of reproduction of capital. The business class is called to exercise its role through the discourse that appeals to social responsibility programs, in order to intervene directly in the "social question". The core of this research is precisely this point. Although there is considerable scholarship on the phenomenon of Social Responsibility and Corporate Citizenship, there is also an evident lack of this approach focused on the banking sector in Brazil. The importance of rentier capital increased ownership of shares in the wealth produced by all of Brazilian society, justifies a sociological research project on Social Responsibility in the domestic financial sector. In this sense, it was decided to perform a dynamic approach to the "Corporate Citizenship" in the banking industry, specifically in the Bank of Brazil. As this is a key institution, is important analyze of the impacts of this strategy fetish of capitalist reproduction, in order to evaluate the social legitimization of rentier capital in Brazil. In this scenario of the abundance of the discourse on social responsibility there exist a progressive impoverishment of professional work in this segment in Brazil. There is a dramatic mismatch between rhetoric and practice because of the trend of deepening vulnerability of the working conditions of the Brazilian bank worker, from the 1990's. In the specific case of the Bank of Brazil, the first initiative of the institution was to conform to the principles of the UNO and the Ethos Institute, aiming to align their domestic policies to this new strategy of domination of capital. The purpose is to place the Bank in the ideological sphere of corporate social responsibility, just as with its partners in the private financial intercapitalist competition. Indeed, in the internal ambit of the Bank of Brazil, there is a policy to adjust its functional segments to the doctrine of Social Corporate Responsibility. The concepts of this doctrine is presented as something inexorable. There are no alternatives. The Bank of Brazil operates in a highly competitive market, the segment featuring the dominance of financial capital accumulation today. For this reason it can not fail to incorporate the technological advances organizational. For employees there is no alternative but to adapt to this new set of ideas proposed by the metabolism of capital

Terceirização versus agenda do trabalho decente : estudo de caso a partir do Banco do Brasil s.a. na Paraíba

This Dissertation examines outsourcing in Bank of Brazil SA, the state of Paraiba. The central research question is to what extent this flexibility of labor relations incorporates items claimed by ´recent´ Decent Work Agenda of the International Labour Organization (OIT) or, on the contrary, the ´epidemic´ of outsourcing makes it even more challenging the world of work in the third millennium. The research hypothesis is that the Bank of Brazil has a growing subcontracting / outsourcing of labor (companies and individuals) and that not only contributes to the deterioration of working conditions, but also opposes the Work Agenda decent. Aiming to prove or disprove the hypothesis, the study includes a survey and secondary field. The literature review focuses on the trend towards casualization of labor in capitalism, and yet, in an effort to systematize data and analysis on ´outsourcing´ from the viewpoint of different actors. This theoretical framework is anchored in important classical sources and present that address the topic in the world and in Brazil. The field research was conducted with the actors related to the theme of ´outsourcing´ the Bank of Brazil - Paraiba, precisely branch managers, permanent employees of the bank, union representatives (bank workers), union bank and outsourced. The results confirm, in part, the study hypothesis, by demonstrating that there are several meanings and forms of precariousness that the contractors surveyed are submitted, highlighting the issue of salaries, the work environment, union representation and health worker. All these themes, each for himself, are contemplated by the Decent Work Agenda of the ILO and show, according to field research, rather fragile

Ações de profissionais relativas ao banco de leite humano : uma perspectiva de mudança

This is an exploratory and descriptive study that aimed to investigate the actions of professionals in the context of breastfeeding, on the assumption that the actions taken by employees working together to postpartum and newborn are not competing to effect the distribution of pasteurized human milk so that it meets the needs of infants who depend on it. Thus, the study aimed to analyze the actions of medical and nursing staff of the distribution of pasteurized human milk to the newly born. The investigation was developed by action research in a federal hospital, located in the capital the state of Rio Grande do Norte, Brazil, reference assistance to women during pregnancy, childbirth and postpartum high risk in 2010. Study participants were fifty-five professionals chosen from the following inclusion criteria: to act in the NICU or rooming, being a pediatrician and / or neonatologists, nurses and technical nursing. According to the methodology of action research a questionnaire was applied, techniques in focus groups and courses were developed, and, finally, action evaluation. The project was submitted to the Ethics Committee at the Federal University of Rio Grande do Norte and approved with no protocol 448/2009. The problems identified in the responses issued by the social research were grouped into categories according to the similarity between them. The answer to the question of the survey - How is the need for pasteurized human milk for the newborns in neonatal intensive care unit and rooming identified? - Brought subsidies for action planning and implementation of strategies for change in the practice of professionals working in rooming and ICU. Thus, the study has relevance in social care and, when at the local level, will compete for the distribution pasteurized human milk to take effect as best as possible, as recommended by the Ministry of Health. It is also conceived that, in a macro view of society, it could contribute to minimizing the health problem that involves the child population

Doenças sem doentes: Ocorrência de Distúrbios Osteomusculares Relacionados ao Trabalho DORT nos operadores de caixa de um banco

The changes incurred in the financial system with the introduction of new technologies and new forms of administration of banks has caused impact on the health of workers. These changes, which passed in the process of work, generate a combined share of the risk factors that result in numerous injuries and illnesses among banks, notably between the operators of banks tellers. The Work-Related Musculoskeletal Disordes - WRMD represent a group of occupational diseases always present among these workers. Because of its high incidence and the amount of financial resour envolved to manage the problem has been the object of constant study. This paper aims to analyze the bank teller activity; search the occurrence of WRMD in the activity, identifying the factors determining the occurrence of WRMD in the activity and determine the real number of touchs on a keyboard made by the operator and propose solutions that influence the reduction of illness in the workplace of the bank teller. Methodological tools of ergonomics are used to provide a broad knowledge of aspects of work that have been studied and influential in the generation of occupational diseases studied. It was found that activity put workers to serious risk of occupational diseases. As the main contributory factors and determinants for this illness: the requirements and control the numbers daily endorsements; evaluation system based on performance targets for productivity; management system at time of service to customers; work with stressful factors (broken box); excess of time worked; furniture of workstations with ergonomic inadequacies and policy for the prevention of occupational diseases inefficient. They have also noted cases of illness for DORT workers without fulfilling the legal requirement of the issuance of the communication of labour accident and without the removal of the employee of the workplace

Controle Adaptativo Robusto para Filtros Ativos de Potência Paralelo

Conventional control strategies used in shunt active power filters (SAPF) employs real-time instantaneous harmonic detection schemes which is usually implements with digital filters. This increase the number of current sensors on the filter structure which results in high costs. Furthermore, these detection schemes introduce time delays which can deteriorate the harmonic compensation performance. Differently from the conventional control schemes, this paper proposes a non-standard control strategy which indirectly regulates the phase currents of the power mains. The reference currents of system are generated by the dc-link voltage controller and is based on the active power balance of SAPF system. The reference currents are aligned to the phase angle of the power mains voltage vector which is obtained by using a dq phase locked loop (PLL) system. The current control strategy is implemented by an adaptive pole placement control strategy integrated to a variable structure control scheme (VS-APPC). In the VS-APPC, the internal model principle (IMP) of reference currents is used for achieving the zero steady state tracking error of the power system currents. This forces the phase current of the system mains to be sinusoidal with low harmonics content. Moreover, the current controllers are implemented on the stationary reference frame to avoid transformations to the mains voltage vector reference coordinates. This proposed current control strategy enhance the performance of SAPF with fast transient response and robustness to parametric uncertainties. Experimental results are showing for determining the effectiveness of SAPF proposed control system

Técnica de controle adaptativo robusto aplicada a filtros ativos de potência e paralelo

The Methods for compensation of harmonic currents and voltages have been widely used since these methods allow to reduce to acceptable levels the harmonic distortion in the voltages or currents in a power system, and also compensate reactive. The reduction of harmonics and reactive contributes to the reduction of losses in transmission lines and electrical machinery, increasing the power factor, reduce the occurrence of overvoltage and overcurrent. The active power filter is the most efficient method for compensation of harmonic currents and voltages. The active power filter is necessary to use current and voltage controllers loop. Conventionally, the current and voltage control loop of active filter has been done by proportional controllers integrative. This work, investigated the use of a robust adaptive control technique on the shunt active power filter current and voltage control loop to increase robustness and improve the performance of active filter to compensate for harmonics. The proposed control scheme is based on a combination of techniques for adaptive control pole placement and variable structure. The advantages of the proposed method over conventional ones are: lower total harmonic distortion, more flexibility, adaptability and robustness to the system. Moreover, the proposed control scheme improves the performance and improves the transient of active filter. The validation of the proposed technique was verified initially by a simulation program implemented in C++ language and then experimental results were obtained using a prototype three-phase active filter of 1 kVA

Avaliação da eficiência de filtros anaeróbios na remoção de coliformes fecais e ovos de helmintos

The technology of anaerobic reactors for sanitary wastewater treatment has been extensively developed in Brazil, and today it is practically consolidated. They present several advantages, such as low construction and operating costs, and low sludge production, the anaerobic reactors are an attractive alternative to minimize problematic lack of basic sanitation in urban areas, and also of the rural areas. The anaerobic filters have been widely used in Brazil. It produces an effluent with low concentration of organic matter and solids suspended, besides conserving the nutrients, therefore, it is good for use in irrigation, but the practice must be associated with knowledge of the pathogens presence. The main objective of this study was to evaluate the efficiency of anaerobic filters in removal faecal coliforms and helminth eggs, and to verify if the effluent can be used for agricultural purposes, according to the World Organization of Health (WHO, 1989). The protocol used to enumerate helminths eggs was the modified Bailenger method, (Ayres and Mara, 1996) recommended by WHO for evaluation of raw effluent and treated effluent. The membrane filtration method was utilized to determine the concentrations of faecal coliforms. Three different systems of sewer treatment composed by anaerobic filters were analyzed. The results, in a general analysis, showed that all the researched systems reached a larger removal than 93% to helminth eggs, resulting in an effluent with smaller average than 1 egg/L. One of these systems, Sistema RN, reached a larger removal than 99%, confirming the good performance of the anaerobic filters in removal helminths eggs. Even with low concentrations of eggs in the influent, the filters were capable to remove this parameter efficiently. About faecal coliforms, it was observed for all the researched systems an effluent with 106 CFU/100mL. The high concentrations to faecal coliforms in the effluent just allow reuse for restricted irrigation, in agreement with the guidelines of WHO. Although the researched systems have not removed faecal coliforms efficiently, the results indicated a good efficiency of the anaerobic filters in removal helminth eggs

This study investigates a new treatment system of wastewater by anaerobic and aerobic biological filters for nitrogen modification. The main objective of this study was evaluate, on a pilot scale, quantitatively and qualitatively the bacterian nitrifying community in a experimental sewage treatment system made by aerobics biological filters in series, in search of figure out the dynamic of nitrogen modification process. It was collected and laboratorial analysed microbiologically, regarding NMP of Nitrosomonas e Nitrobacter, and physical-chemically considering nitrogen sequence. We conclude that: the association in aerobic biological filters under nutrition controlled conditions and oxygen level allows the appearance of bacterian community responsible for the nitrogen modification; the method used, despite its limitations, provided the selection of autotrophic nitrifying microorganisms, allowing the identification of Nitrosomonas and Nitrobacter; the flow direction tested in the experimental unit did not affect the nitrifying bacterial community, certainly because they were kept drowned and did not occur flow speed that could breake the formed biomass; the nitrification process happened in aerated biological filters in all phases of the research, comproved by microbiological tests; in the third phase of the research the increase of the oxygen rate was significant for the nitrificant bacterian community in the aerate biological filters, allowing its growth, occurring relation between the efficiency of nitrification system and the quantity of organisms responsible for this process; the conduit used in aerated biological filters showed satisfactory performance support material to the nitrifying bacteria development

Nitrificação de efluentes de reatores anaeróbicos em filtros submersos aerados

Although the good performance in organic matter and suspended solids removal, the anaerobic reactors are unable to remove ammonia nitrogen from sewage, which makes indispensable to include a step of post-treatment for removal of ammonia or nitrate as necessary. This paper presents the performance of a new variant technology, where the nitrification unit, preceded by anaerobic units, is a submerged aerated biological filter, without continuous sludge discharge in their daily operation. The oxygenation system is very simple and inexpensive, consisting of perforated hoses and compressors. The anaerobic reactors are a septic tank with two chambers followed (8.82 m³) and two parallel anaerobic filters (36 m³ each) filled with ceramic bricks and conics plastic parts. Both followed aerated filters were filled with cut corrugated conduit. The study evaluated the behavior of the system with constant domestic sewage flow (10 m³/d) and different aeration conditions, are these: stage 01, when applied air flow of 0.01 m³ air/min in both aerated filter; stage 02, remained in the initial air flow rate in the second aerated filter and increased at the first to 0.05 m³ air/min; at last, at last, in stage 03, the air flow rate of first aerated filter was 0.10 m³ air/min and on the second remained at 0.01 m³ air/min. The filter FA1 received load of 0.41 kg COD/m³.d, 0.37 kg COD/m³.d and 0.26 kg COD/m³.d on phases 01, 02 and 03, respectively. The FA2 received loads of 0.25 kg COD/m³.d, 0.18 kg COD/m³.d and 0.14 kg COD/m³.d on phases 01, 02 and 03, respectively. During stage 01, were found the following results: 98% removals of BODtotal and 92% of CODtotal, with effluent presenting 9 mg/L of BODtotal final average and 53 mg/L of CODtotal average; suspended solids removals of 93%, with a mean concentration of 10 mg/L in the final effluent; 47% reduction of ammonia of FA2 to FAN 's, presenting average of 28 mg NNH3/ L of ammonia in the effluent with; the dissolved oxygen levels always remained around 2.0 mg/L. During stage 02, were found removals of 97% and 95% to BODtotal and suspended solids, respectively, with average final concentrations of 8 and 7 mg/L, respectively; was removed 60% of ammonia, whose final concentration was 16.3 mg NNH3/ L, and nitrate was increased to a final average concentration of 16.55 mg N-NO3/L. Finally, the stage 03 provided 6 mg/L of DBOtotal (98% removal) and 23 mg/L of CODtotal (95% removal) of final effluent concentrations average. At this stage was identified the higher ammonia oxidation (86%), with final effluent showing average concentration of 6.1 mg N-NH3/L, reaching a minimum of 1.70 mg N-NH3/L. In some moments, during stage 03, there was a moderate denitrification process in the last aerated filter. The average turbidity in the effluent showed around 1.5 NTU, proving the good biomass physical stability. Therefore, the results demonstrate the submerged biological filters potential, filled with high void ratio material (98%), and aerated with hoses and compressor adoption, in the carbonaceous and nitrogenous matter oxidation, also generating an effluent with low concentration of solids

Filtros acústicos em cristais fonônicos

In this work, we have studied the acoustic phonon wave propagation within the periodic and quasiperiodic superlattices of Fibonacci type. These structures are formed by phononic crystals, whose periodicity allows the raise of regions known as stop bands, which prevent the phonon propagation throughout the structure for specific frequency values. This phenomenon allows the construction of acoustic filters with great technological potential. Our theoretical model were based on the method of the transfer matrix, thery acoustics phonons which describes the propagation of the transverse and longitudinal modes within a unit cell, linking them with the precedent cell in the multilayer structure. The transfer matrix is built taking into account the elastic and electromagnetic boundary conditions in the superllatice interfaces, and it is related to the coupled differential equation solutions (elastic and electromagnetic) that describe each model under consideration. We investigated the piezoelectric properties of GaN and AlN the nitride semiconductors, whose properties are important to applications in the semiconductor device industry. The calculations that characterize the piezoelectric system, depend strongly on the cubic (zinc-bend) and hexagonal (wurtzite) crystal symmetries, that are described the elastic and piezoelectric tensors. The investigation of the liquid Hg (mercury), Ga (gallium) and Ar (argon) systems in static conditions also using the classical theory of elasticity. Together with the Euler s equation of fluid mechanics they one solved to the solid/liquid and the liquid/liquid interfaces to obtain and discuss several interesting physical results. In particular, the acoustical filters obtained from these structures are again presented and their features discussed

O comprometimento no trabalho e o significado do trabalho :um estudo com os funcionários do Banco do Nordeste do Brasil S/A

The current study analyses the relation between commitment (focusing on organization, career and syndicate) and the meaning of the work for 123 employees from a bank of mixed economy, crowed in agencies located in the Northeast capitals and also in four capitals out of this region: Belo Horizonte-MG, Brasília-DF, Rio de Janeiro-RJ and São Paulo-SP. It explores the commitment variability in the work of participants, as well as the score combination in foci, generating the commitment patterns, having used as an instrument a questionnaire consisting: a reduced version of OCQ Organizational Commitment Questionnaire (09 items), which measures the organizational commitment; the reduced Gordon s Scale (10 items), which measures the syndicate commitment; and the Blau s Scale, which measures the commitment to the career/occupation. It speculates, likewise, the meaning of work variability to the sample, seeking for the value attributes (what work should be), descriptive attributes (what work is) and its hierarchy, for which the ISMT-Inventário do Significado e Motivação no Trabalho has been applied; the work centrality, for which two specific inquires were used. The answers were registered in data at SPSS-Statically Package for Social for Windows, and from this point the statistical analyses were accomplished. Eight commitments to work patterns and six from the meaning of work were identified (Cluster analyses). The relation between both constructs was confirmed, corroborating other studies
