The Brazilian 1994 stabilization plan: an analytical view

The Real Plan has succeeded in stabilizing the Brazilian inflation. The consumer price inflation has been reduced from 11260 percent per year, in June 1994, to an estimate of 8 percent in 1997. The lower inflation resulted in a remarkable income distribution, and in an increased private consumption. The plan managed to control the inflationary effects of the increased demand with some traditional measures: A more liberalized economy, a moving (and overvalued) exchange rate band, high interest rate differentials, and a tight domestic credit policy. The government has, so far failed to accomplish the fiscal adjustment. The price stabilization has largely depended on the current account deficit. However, macroeconomic indicators do not present reasons for concern about the current account sustainability, in the medium-run. The economy may be trapped in a low-growth vicious cycle, represented by a stop-and-go trend, due to the two-way endogencity between domestic saving and growth. Economic growth depends on policies in increase the public sector saving, to secure the privatization of the State enterprises, and to promote investments. The major problem for the government action is, as always, in the political sphere. Approximately 80 percent of the Central Government net revenue are allocated to the social sectors. Consequently, the fiscal reform will hue to deal with the problem of re-designing the public sector’s intervention in the social area. Most probably, it will be inevitable to cut the social area budget. This is politically unpleasant.

O campo criminalística: uma abordagem da cultura organizacional à luz da filosofia da ação de Pierre Bourdieu

A cultura organizacional tem se revelado um excelente instrumento analítico em Administração. Sob seu prisma, as organizações têm sido estudadas com o intuito de estabelecer-se ou construir-se uma identidade como modo de alavancar as suas atuações. O presente trabalho, nessa seara, explora os conceitos de cultura e cultura organizacional para melhor amoldar-se aos seus objetivos. Optou-se, nesse contexto, por usar os conceitos firmados pela filosofia da ação de Pierre Bourdieu - Campo, Capitais e habitus -, uma vez que diferenciam-se das demais teorias da cultura por trazer uma concepção relacional entre estrutura e atores sociais, entre objetividade e subjetividade. Utilizando-se desse arcabouço teórico, delimitou-se o Campo Criminalística a partir dos Capitais que ali estão em jogo, sobretudo o Capital nomeado de Forense, diferenciando-o dos demais Campos que o tangenciam: Polícia, Jurídico e Científico. Diante dessa delimitação e a partir de um estudo de caso sobre o Instituto de Criminalística do Distrito Federal, foi possível, ainda, estabelecer os principais elementos cognitivos que compõem o habitus dos Peritos Criminais que ali atuam, cotejando-os, sobretudo, com o habitus do policial, traçando diferenças e possíveis similitudes e irrigações.

Relações entre conhecimento e trabalho no contexto de uma instituição financeira : a experiência no Banco do Brasil

O tema desta tese é a Gestão do Conhecimento, abordagem em evidência crescente nos meios acadêmicos e empresariais, espaços em que o conhecimento começa a ser visto como recurso substituto do trabalho. A discussão da ruptura entre os conceitos de conhecimento e trabalho vigora desde a antiguidade até os dias de hoje. E foi esse argumento de ruptura que impulsionou a definição do foco desta pesquisa: a discussão das relações entre conhecimento e trabalho, e a forma como esses conceitos interagem no contexto das organizações. A pesquisa de campo foi realizada em uma instituição financeira brasileira de grande porte, o Banco do Brasil, diante do contexto do sistema financeiro. Buscou-se construir um quadro referencialteórico das relações entre conhecimento e trabalho nessa empresa. Para o desenvolvimento da tese, foi utilizado um referencial teórico multidisciplinar baseado nas interfaces da Gestão do Conhecimento com a Filosofia (concepções de vita contemplativa e vita activa) a Sociologia (o conhecimento como construção social e histórica) e a Psicologia (o conhecimento associado ao desenvolvimento humano). Para a realização da pesquisa, optou-se por um método de orientação pós-moderna, que se admite o uso das técnicas científicas mais recentes, sem excluir o uso de abordagens tradicionais. Entende-se que a visão pós-moderna transcende a modernidade, sem excluí-la. Para a coleta de informações, foi utilizada uma abordagem multimétodos, que abrangeu a aplicação das seguintes técnicas: questionários fechados, entrevistas em profundidade, observação participante e análise documental. Os questionários foram aplicados, exclusivamente, junto a profissionais do Banco do Brasil. As entrevistas em profundidade foram realizadas com profissionais do Banco do Brasil e de outros bancos públicos e privados (das cinco regiões do país) e também com representantes do Sindicato dos Bancários de Brasília e com um técnico do Instituto de Pesquisa Econômica Aplicada - IPEA. Como resultados da pesquisa, foram identificadas seis categorias analíticas (Concepção de Gestão do Conhecimento, Ambiente de Trabalho, Compartilhamento de Conhecimento, Aprendizagem, Identidade Profissional e Identidade Corporativa) as quais são necessárias para a compreensão das relações entre conhecimento e trabalho no âmbito da instituição finaceira pesquisada. A partir desses resultados, foi construído um modelo teórico da Gestão do Conhecimento.

Analytical characterization of the aroma of Tinta Negra Mole red wine: Identification of the main odorants compounds

A method for the simultaneous determination of major and minor volatiles composition in different types (dry, medium dry, sweet and medium sweet) of a young Tinta Negra Mole (TNM) monovarietal red wine from 2003 harvest has been validated. Wine samples preparation includes a dichloromethane liquid–liquid extraction followed by concentration under a nitrogen atmosphere. The extracted fraction was analysed by gas chromatography–mass spectrometry and give quantitative information for more than 86 analytes whose concentration range from few μg l−1 to 259.1 mg l−1. The method enables high recovery of volatile compounds in wine good linearity with (r2) values higher than 0.980 and good sensitivity. The limits of detection range from 0.003 to 0.534 mg l−1 and limits of quantification from 0.009 to 1.170 mg l−1. The method allows satisfactory determination of more than 80 compounds in the TNM red wines. These wines are characterized by a high content of higher alcohols, ethyl esters, fatty acids and lactones. The levels of sulphur compounds in Tinta Negra Mole medium sweet wines are very low, but they have the highest concentration of carbonyl compounds. Quantitative analysis of the main odorants followed by the determination of aroma index allow us elucidate the aroma of these varieties. On the basis of their odour description and odour threshold, the most powerful odorants of Tinta Negra Mole wines were tentatively established.

Headspace solid-phase microextraction combined with mass spectrometry as a powerful analytical tool for profiling the terpenoid metabolomic pattern of hop-essential oil derived from Saaz variety

Hop(HumuluslupulusL.,Cannabaceaefamily)isprizedforitsessentialoilcontents,usedin beer production and, more recently, in biological and pharmacological applications. In this work,a methodinvolvingheadspace solid-phase microextractionand gas chromatography– mass spectrometry was developed and optimized to establish the terpenoid (monoterpenes and sesquiterpenes) metabolomic pattern of hop-essential oil derived from Saaz variety as a mean to explore this matrix as a powerful biological source for newer, more selective, biodegradable and naturally produced antimicrobial and antioxidant compounds. Different parameters affecting terpenoid metabolites extraction by headspace solid-phase microextraction were considered and optimized: type of fiber coatings, extraction temperature, extraction time, ionic strength, and sample agitation. In the optimized method, analytes were extracted for 30 min at 40 C in the sample headspace with a 50/30 m divinylbenzene/carboxen/polydimethylsiloxane coating fiber. The methodology allowed the identification of a total of 27 terpenoid metabolites, representing 92.5% of the total Saaz hop-essential oil volatile terpenoid composition. The headspace composition was dominated by monoterpenes (56.1%, 13 compounds), sesquiterpenes (34.9%, 10), oxygenated monoterpenes (1.41%, 3), and hemiterpenes (0.04%, 1) some of which can probably contribute to the hop of Saaz variety aroma. Mass spectrometry analysis revealed that the main metabolites are the monoterpene -myrcene (53.0±1.1% of the total volatile fraction), and the cyclic sesquiterpenes, -humulene (16.6 ± 0.8%), and -caryophyllene (14.7 ± 0.4%), which together represent about 80% of the total volatile fraction from the hop-essential oil.

Vigilância eletrônica no trabalho bancário: do controle consentido ao totalitarismo corporativo

This dissertation addresses the electronic surveillance theme in the banking context. The research that originated it, which was held in an organization called for the fiction name Banco Total, started from the following driving question: How do workers at a bank perceive electronic surveillance at their process of work? The research s main objective was to comprehend how workers perceive electronic surveillance at their process of work. The study adopted an interdisciplinary perspective, having Management as the original field, establishing a dialogue with others disciplines, like Philosophy and Sociology. About its methodology, it s a qualitative research that addressed its object in oral (interviews with live history elements) way. . Ten individuals were interviewed. The analytical process utilized the hermeneutical-dialectics technique.. From the analyses (hermeneutics) of the data, the following themes have emerged: (i) Acquiescence ; (ii) Monitoring; (iii) Time and Motion; (iv) Fear; (v) Interdiction; and (vi) Resistance . From the discussion (dialectic) of the results, this work presents three synthetic propositions that culminate in the following dimensions (i) control; (ii) acquiescence; (iii) corporative totalitarianism. It can be concluded that electronic surveillance is one mechanism of control emerged from the apply of technology at Total Bank; that information technology has been improving the control mechanisms of management theories; and that the imbrications between management and material technology control mechanisms at a context where there is acquiescence by workers contribute for the emergency of corporative totalitarianism components

Development of a new analytical approach based on cellulose membrane and chelator for differentiation of labile and inert metal species in aquatic systems

A new procedure was developed in this study, based on a system equipped with a cellulose membrane and a tetraethylenepentamine hexaacetate chelator (MD-TEPHA) for in situ characterization of the lability of metal species in aquatic systems. To this end, the DM-TEPHA system was prepared by adding TEPHA chelator to cellulose bags pre-purified with 1.0 mol L-1 of HCl and NaOH solutions. After the MD-TEPHA system was sealed, it was examined in the laboratory to evaluate the influence of complexation time (0-24 h), pH (3.0, 4.0, 5.0, 6.0 and 7.0), metal ions (Cu, Cd, Fe, Mn and Ni) and concentration of organic matter (15, 30 and 60 mg L-1) on the relative lability of metal species by TEPHA chelator. The results showed that Fe and Cu metals were complexed more slowly by TEPHA chelator in the MD-TEPHA system than were Cd, Ni and Mn in all pH used. It was also found that the pH strongly influences the process of metal complexation by the MD-TEPHA system. At all the pH levels, Cd, Mn and Ni showed greater complexation with TEPHA chelator (recovery of about 95-75%) than did Cu and Fe metals. Time also affects the lability of metal species complexed by aquatic humic substances (AHS); while Cd, Ni and Mn showed a faster kinetics, reaching equilibrium after about 100 min, and Cu and Fe approached equilibrium after 400 min. Increasing the AHS concentration decreases the lability of metal species by shifting the equilibrium to AHS-metal complexes. Our results indicate that the system under study offers an interesting alternative that can be applied to in situ experiments for differentiation of labile and inert metal species in aquatic systems.

Linguagem, cognição e mundo: o livro do desassossego e a construção discursiva da realidade

This study analyzes the processes of meaning construction in the Livro do Desassossego, by semi-heteronym Bernardo Soares - Fernando Pessoa. We use theoretical grounds from an interface between Cognitive Linguistics and Textual Linguistics to observe how certain linguistic mechanisms build a reality that tells us of a time, a being and his conceptions of language and writing. We focus on description and explanation of procedures of categorization and referentiation accomplished, for example, through metaphor and metonymy. For the construction of the intended theoretical interface, we use analytical categories proposed and developed by the Socio-cognitive Approach of Language, Conceptual Metaphor Theory and Mental Space Theory. Armed with this theoretical background, we observed the dynamics of language in relation to its social, cultural and historical features, as well as the cognitive aspects that underlie it. We seek, therefore, encourage discussions about the functioning of language considering primarily the creative processes that allow us to organize and shape our experiences. We also try to provide an approximation of Linguistics, Literature and Philosophy, with a view to relations between language structure, cognitive activity and socio-cultural organization. From the results obtained, we found that a literary text attests, with a particular property, the mutual relations between language, cognition and culture, as indicates cognitive approach to language studies
