Pax Americana ou o império da insegurança?

No artigo pretende-se mostrar a posição dos Estados Unidos em um diferente contexto conceitual e histórico, como tentativa de escapar-se do imediatismo da discussão atual do país como um poder imperial ou hegemônico, trazidos pelos debates atuais. Revela-se assim, problemas de definições dos conceitos de imperialismo e hegemonia, assim como da dominação formal/infomal distorcendo a real imagem e posição da América do Norte no campo internacional nos dias atuais.

Type checking cryptography implementations

Cryptographic software development is a challenging eld: high performance must be achieved, while ensuring correctness and com- pliance with low-level security policies. CAO is a domain speci c language designed to assist development of cryptographic software. An important feature of this language is the design of a novel type system introducing native types such as prede ned sized vectors, matrices and bit strings, residue classes modulo an integer, nite elds and nite eld extensions, allowing for extensive static validation of source code. We present the formalisation, validation and implementation of this type system

Novas tecnologias e desempenho operacional: um estudo internacional comparativo

Este estudo investiga a influência da antecipação de novas tecnologias sobre o desempenho em empresas de manufatura. Complementarmente, foi realizada uma análise comparativa entre plantas industriais localizadas em outros países e no Brasil. Para testar essas questões, foram coletados dados de 337 empresas em 11 países, incluindo o Brasil. Aspectos-chave na gestão de operações, como estratégia de manufatura, integração funcional, gestão da cadeia de suprimentos e parceria com fornecedores, foram considerados relevantes para antecipação de novas tecnologias por empresas. Os resultados sugerem que estratégia de manufatura, integração funcional e parceria com fornecedores são importantes para a antecipação de novas tecnologias por empresas localizadas em outros países, enquanto apenas a integração funcional é importante para as empresas brasileiras. Por fim, existem evidências que sugerem um impacto positivo entre antecipação de novas tecnologias e desempenho operacional, tanto para as empresas internacionais como para as empresas brasileiras.

A influência do controlo do acesso à internet na satisfação com o trabalho

RESUMO: A presente investigação incide no estudo da influência das dimensões do controlo do acesso à Internet, propostas por Hackman e Oldham (1975), e das facetas da satisfação com o trabalho, propostas por Spector (1985) num contexto organizacional. Os dados foram obtidos através da aplicação de três escalas avaliativas: o "Job Diagnostic Survey" (JDS), o "Job Satisfaction Survey" (JSS), e uma escala criada para avaliar as dimensões do controlo do acesso à Internet. O estudo incidiu numa amostra de conveniência, constituída por 135 colaboradores pertencentes a três organizações. Os resultados obtidos demonstraram que apenas três dimensões revelaram relações de antecedência com as dimensões da satisfação com o trabalho: no bloqueio a páginas e aplicações foram identificadas relações de antecedência com a da satisfação com os benefícios adicionais e com a promoção. Quanto à voz nas políticas da organização foram identificadas relações com a satisfação com os colegas, e com a natureza do trabalho. E na legislação foram identificadas relações com a satisfação com as recompensas contingenciais, com as condições operantes e com a comunicação. Os resultados levaram à não confirmação do modelo em análise, por não estar em linha com o quadro teórico estabelecido. Foram discutidas algumas das implicações dos resultados obtidos. ABSTRACT: The current research focus in the study of influence between the Internet Access control dimensions, proposed in this study, and the global Job satisfaction, proposed by Hackman e Oldham (1975) and the job satisfaction facets proposed by Spector (1985) in a organizationsl context. The data eas obtained through the application of three scales: num contexto organizacional. "Job Diagnostic Survey" (JDS), the "Job Satisfaction Survey" (JSS),and a scale that was created to evaluate the internet Access control. The study focused on a convenience sample, constituted by 135 participants from three organizations. The results show that only three dimensions revealed to have an antecedent relationship with the job satisfaction dimensions: in the websites and applications blocking, it was identified as having an antecedent relationship with the satisfaction with fringe benefits and promotion. Voice in the organizational policies was verified as an antecedent to the dimensions of the satisfaction with the coworkers and with the nature of work. And finally, the legislation was confirmed as an antecedent in the relationship with the dimensions satisfaction with contingent rewards, operating conditions and communication. The results led to the non confirmation of the studied theoretical model. Some of these results implications were discussed.

Asymmetric synthesis of N-aryl aziridines

The reactions of a variety of N-arylhydroxamates as nitrogen transfer reagents to acryloyl derivatives of (−)-8-phenylmenthol, (−)-quinine and (−)-Oppolzer’s sultam acting as Michael acceptors was studied. Poor to modest diastereoselection was observed in the formation of aziridines. The absolute structure of one of the pure diastereomers secured from Oppolzer’s auxiliary was established by X-ray crystallography and hence the absolute configuration of the derived methyl-N-phenylaziridine-2-carboxylate could be assigned. Whilst only poor facial selectivity was observed for chiral hydroxamic acid prepared from dehydroabietic acid, moderate to good enantioselection of aziridines could be achieved with the chiral quaternary salts based on cinchona alkaloids, especially with that of cinchonine. A model is presented to explain the origin of enantioselection and a mechanism is proposed for the aziridination reaction.

Infant mortality rates according to socioeconomic status in a Brazilian city

OBJECTIVE: Data from municipal databases can be used to plan interventions aimed at reducing inequities in health care. The objective of the study was to determine the distribution of infant mortality according to an urban geoeconomic classification using routinely collected municipal data. METHODS: All live births (total of 42,381) and infant deaths (total of 731) that occurred between 1994 and 1998 in Ribeirão Preto, Brazil, were considered. Four different geoeconomic areas were defined according to the family head's income in each administrative urban zone. RESULTS: The trends for infant mortality rate and its different components, neonatal mortality rate and post-neonatal mortality rate, decreased in Ribeirão Preto from 1994 to 1998 (chi-square for trend, p<0.05). These rates were inversely correlated with the distribution of lower salaries in the geoeconomic areas (less than 5 minimum wages per family head), in particular the post-neonatal mortality rate (chi-square for trend, p<0.05). Finally, the poor area showed a steady increase in excess infant mortality. CONCLUSIONS: The results indicate that infant mortality rates are associated with social inequality and can be monitored using municipal databases. The findings also suggest an increase in the impact of social inequality on infant health in Ribeirão Preto, especially in the poor area. The monitoring of health inequalities using municipal databases may be an increasingly more useful tool given the continuous decentralization of health management at the municipal level in Brazil.

Voluntary HIV counseling and testing during prenatal care in Brazil

OBJECTIVE: Voluntary HIV counseling and testing are provided to all Brazilian pregnant women with the purpose of reducing mother-to-child HIV transmission. The purpose of the study was to assess characteristics of HIV testing and identify factors associated with HIV counseling and testing. METHODS: A cross-sectional study was carried out comprising 1,658 mothers living in Porto Alegre, Brazil. Biological, reproductive and social variables were obtained from mothers by means of a standardized questionnaire. Being counseling about HIV testing was the dependent variable. Confidence intervals, chi-square test and hierarchical logistic model were used to determine the association between counseling and maternal variables. RESULTS: Of 1,658 mothers interviewed, 1,603 or 96.7% (95% CI: 95.7-97.5) underwent HIV testing, and 51 or 3.1% (95% CI: 2.3-4.0) were not tested. Four (0.2%) refused to undergo testing after counseling. Of 51 women not tested in this study, 30 had undergone the testing previously. Of 1,603 women tested, 630 or 39.3% (95% CI: 36.9-41.7) received counseling, 947 or 59.2% (95% CI: 56.6-61.5) did not, and 26 (1.6%) did not inform. Low income, lack of prenatal care, late beginning of prenatal care, use of rapid testing, and receiving prenatal in the public sector were variables independently associated with a lower probability of getting counseling about HIV testing. CONCLUSIONS: The study findings confirmed the high rate of prenatal HIV testing in Porto Alegre. However, women coming from less privileged social groups were less likely to receive information and benefit from counseling.

Barriers for HIV testing during pregnancy in Southern Brazil

OBJECTIVE: To assess HIV testing rate and determine risk factors for not have been tested during pregnancy. METHODS: A cross-sectional study was carried out in Porto Alegre, Southern Brazil, from December 2000 to February 2001. Socioeconomic, maternal and healthcare variables were obtained by means of a standardized questionnaire. Crude and adjusted odds ratios and their 95% confidence intervals were obtained in logistic regression models. RESULTS: A total of 1,642 mothers were interviewed. Of them, 94.3% reported being offered HIV testing before or during pregnancy or during labor; 89 mothers (5.4%) were not tested or did not know if they were tested. Attending fewer than six prenatal visits, being single and younger than 18 years old were relevant barriers preventing HIV testing. There was found a relationship between maternal schooling and the category of prenatal care provider. Having low 22.20 (12.43-39.67) or high 3.38 (1.86-7.68). schooling and being cared in the private sector strongly reduced the likelihood of being HIV tested. CONCLUSIONS: The Brazilian Health Ministry's recommendation for universal counseling and HIV testing has been successfully implemented in the public sector. In order to improve HIV testing coverage, new strategies need to target women cared in the private sector especially those of low schooling.

Besnoitia besnoiti protein disulfide isomerase (BbPDI): molecular characterization, expression and in silico modelling

Besnoitia besnoiti is an apicomplexan parasite responsible for bovine besnoitiosis, a disease with a high prevalence in tropical and subtropical regions and re-emerging in Europe. Despite the great economical losses associated with besnoitiosis, this disease has been underestimated and poorly studied, and neither an effective therapy nor an efficacious vaccine is available. Protein disulfide isomerase (PDI) is an essential enzyme for the acquisition of the correct three-dimensional structure of proteins. Current evidence suggests that in Neosporacaninum and Toxoplasmagondii, which are closely related to B. besnoiti, PDI play an important role in host cell invasion, is a relevant target for the host immune response, and represents a promising drug target and/or vaccine candidate. In this work, we present the nucleotide sequence of the B. besnoiti PDI gene. BbPDI belongs to the thioredoxin-like superfamily (cluster 00388) and is included in the PDI_a family (cluster defined cd02961) and the PDI_a_PDI_a'_c subfamily (cd02995). A 3D theoretical model was built by comparative homology using Swiss-Model server, using as a template the crystallographic deduced model of Tapasin-ERp57 (PDB code 3F8U chain C). Analysis of the phylogenetic tree for PDI within the phylum apicomplexa reinforces the close relationship among B. besnoiti, N. caninum and T. gondii. When subjected to a PDI-assay based on the polymerisation of reduced insulin, recombinant BbPDI expressed in E. coli exhibited enzymatic activity, which was inhibited by bacitracin. Antiserum directed against recombinant BbPDI reacted with PDI in Western blots and by immunofluorescence with B. besnoiti tachyzoites and bradyzoites.
