A dimensão interdisciplinar da análise documental nos contextos brasileiro e espanhol no âmbito da organização do conhecimento

Information organization can be considered as a nuclear area in Information Science and its historical background has been historically built based on three theoretical approaches: subject cataloguing, under a North-American influence, Indexing, under a British influence, and document analysis, under a French influence. In this sense, although one can consider the strong influence of the logic-linguistic approach of the French tradition in information organization both in Brazil and in Spain, it is not already clear in what extent the mentioned influence specifically occurs in Brazil and Spain as well as what are the dialogical perspectives between them. So, and in order to analyze how the Information Science academic environments in Brazil and in Spain conceive the interdisciplinary relationships in the domain of document analysis (DA), it was applied a questionnaire to Brazilian and Spain DO researchers based on the records of the Brazilian and the Spanish International Society for Knowledge Organization chapters. The results (64,5% of answers in Brazil and 60,6% in Spain) allowed the identification of 35 DA interdisciplinary relationships in Brazil and 98 in Spain, whose data were so grouped in 7 matrixes ? cognitive, philosophical, historical, logic-lingusitic, quantitative, social and political, and technological. It was possible to observe that the logical-linguistic matrix is strongly predominant (90% of the answers in Brazil and in Spain) what reflects the influence of the ideas of Jean-Claude Gardin. On the other side, the graphic visualization of authors´s network showed a strong perspective of dialogical relationships among Brazilian and Spanish DA researchers, based on the convergence of theoretical conceptions, what allow us to conclude the need of joint research policies between both coountries in order to make the mention ed dialogical relationships real and fruitful.

Archival Classification and Knowledge Organization: Theoretical Possibilities for the Archival Field

The main goal of this study is to outline a possible relation between archival classification and knowledge organization theory. In this sense, we seek to contribute to the conceptual classification in Archival Science, since there is a lack of systematization about archival classification; not just classification, but even the study of historical and conceptual aspects of the discipline. In the context of knowledge organization there is a considerable amount of research on how to build classification schemes and indexing systems that can help contribute to and expand archival classification theory. In order to comprehend this vast field of theories and methodologies we construct a parallel comparing the classification concepts in both areas and analyzing these concepts.

El gobierno de las megalópolis, el caso de Brasil, São Paulo: gestión metropolitana, descentralización y participación como desafíos simultáneos

The government of a megalopolis, such as São Paulo, shows singular challenges that do not exist in less complex urban contexts. Being a city of a country with a recent industrialized economy, with an income (functional and geographical) highly concentrated, that has resumed the democracy for only one quarter of a century, this megacity lives with its own political and organizational assignments, due to the contradictory character of the political behavior of its habitants/ voters and of the traditionalist nature of populism and patronage in the relationship between the rulers and the ruled and between the Executive and Legislative powers at the local level. In such context, the difficulties to prosecute the assignments of the metropolitan organization, the decentralization and the institutionalization of citizen participatory channels in the governance and administrative activities are huge. The centrifuge forces (of the decentralization of the local government, through subprefectures), the centripetal forces ( of the metropolitan organization process) and the diffuse forces (of the claiming popular participation) act simultaneously over the deciding processes, in São Paulo, receiving, still, state and national political influences, since the city is a very significant historically producer of political and electoral capital. The analysis of the recent experience of the creation of the subprefectures and the representative counsels (fixed in the Municipality Organic Law of 1990) and the attempt to implement the participatory budgeting, in two occasions (1989-1992 and 2001-2004), reveal some of the social and political reasons that make difficult the establishment of a solidly democratic governance and of a more efficient public administration in the metropolitan area of São Paulo.

Morphological patterns and community organization in leaf-litter ant assemblages

We present a new approach to determine the number and composition of guilds, using the hyperdiverse leaf-litter ant fauna as a model, based on appropriate morphological variables and species co-occurrence null models to describe the complex assemblages of interacting Species Community structure at the 1-m(2) scale. We obtained 18 linear morphometric measures from 949 workers of 171 leaf-litter ant species (18762 measurements) surveyed in four Atlantic Forest localities to test whether the assemblages are morphologically structured; the morphological characters were selected to indicate diet and foraging habits. Principal components analysis was used to characterize the morphospace and to describe the guild structure (number of species and composition). The guild proportionality assembly rule (significant tendency toward constant proportion of species in guilds) was assessed at the 1-m(2) scale. Our analysis indicates that the division of leaf-litter ants into guilds is based mainly on microhabitat distribution in the leaf-litter, body size and shape, eye size, and phylogeny. The same guild scheme applied to four more sites shows that different Atlantic Forest areas have the same leaf-fitter ant guilds. The guild proportionality assembly rule was confirmed for most guilds, Suggesting that there are guild-specific limitations on species coexistence within assemblages; on the other hand, in a few cases the variance in guild proportion was greater than expected under the null assumptions. Other studies on ant functional group classification are partially supported by our quantitative morphological analysis. Our results, however, imply that there are more compartments than indicated in previous models, particularly among cryptic species (confined to soil and litter) and tropical climate specialists. We argue that a general null model for the analysis of species association based oil morphology can reveal objectively defined groups and may thus contribute to a robust theory to explain community structure in general and have important consequences on studies of litter ant community ecology in particular.

Effects of repetitive transcranial magnetic stimulation on clinical, social, and cognitive performance in postpartum depression

Background: This randomized, placebo-controlled, double-blind pilot study evaluated the impact of repetitive transcranial magnetic stimulation (rTMS) on clinical, cognitive, and social performance in women suffering with postpartum depression. Methods: Fourteen patients were randomized to receive 20 sessions of sham rTMS or active 5 Hz rTMS over the left dorsolateral prefrontal cortex. Psychiatric clinical scales and a neuropsychological battery were applied at baseline (pretreatment), week 4 (end of treatment), and week 6 (follow-up, posttreatment week 2). Results: The active rTMS group showed significant improvement 2 weeks after the end of rTMS treatment (week 6) in Hamilton Depression Rating Scale (P = 0.020), Global Assessment Scale (P = 0.037), Clinical Global Impression (P = 0.047), and Social Adjustment Scale-Self Report-Work at Home (P = 0.020). Conclusion: This study suggests that rTMS has the potential to improve the clinical condition in postpartum depression, while producing marginal gains in social and cognitive function.

Coupling Between GABA(A)-R Ligand-Binding Activity and Membrane Organization in beta-Cyclodextrin-Treated Synaptosomal Membranes from Bovine Brain Cortex: New Insights from EPR Experiments

Correlations between GABA(A) receptor (GABA(A)-R) activity and molecular organization of synaptosomal membranes (SM) were studied along the protocol for cholesterol (Cho) extraction with beta-cyclodextrin (beta-CD). The mere pre-incubation (PI) at 37A degrees C accompanying the beta-CD treatment was an underlying source of perturbations increasing [H-3]-FNZ maximal binding (70%) and K (d) (38%), plus a stiffening of SMs' hydrocarbon core region. The latter was inferred from an increased compressibility modulus (K) of SM-derived Langmuir films, a blue-shifted DPH fluorescence emission spectrum and the hysteresis in DPH fluorescence anisotropy (A (DPH)) in SMs submitted to a heating-cooling cycle (4-37-4A degrees C) with A (DPH,heating) < A (DPH,cooling). Compared with PI samples, the beta-CD treatment reduced B (max) by 5% which correlated with a 45%-decrement in the relative Cho content of SM, a decrease in K and in the order parameter in the EPR spectrum of a lipid spin probe labeled at C5 (5-SASL), and significantly increased A (TMA-DPH). PI, but not beta-CD treatment, could affect the binding affinity. EPR spectra of 5-SASL complexes with beta-CD-, SM-partitioned, and free in solution showed that, contrary to what is usually assumed, beta-CD is not completely eliminated from the system through centrifugation washings. It was concluded that beta-CD treatment involves effects of at least three different types of events affecting membrane organization: (a) effect of PI on membrane annealing, (b) effect of residual beta-CD on SM organization, and (c) Cho depletion. Consequently, molecular stiffness increases within the membrane core and decreases near the polar head groups, leading to a net increase in GABA(A)-R density, relative to untreated samples.

Regionalization and access to healthcare in Brazilian states: historical and political-institutional conditioning factors

This article examines the healthcare regionalization process in the Brazilian states in the period from 2007 to 2010, seeking to identify the conditions that favor or impede this process. Referential analysis of public policies and especially of historical institutionalism was used. Three dimensions sum up the conditioning factors of regionalization: context (historical-structural, political-institutional and conjunctural), directionality (ideology, object, actors, strategies and instruments) and regionalization features (institutionality and governance). The empirical research relied mainly on the analysis of official documents and interviews with key actors in 24 states. Distinct patterns of influence in the states were observed, with regionalization being marked by important gains in institutionality and governance in the period. Nevertheless, inherent difficulties of the contexts prejudice greater advances. There is a pressing need to broaden the territorial focus in government planning and to integrate sectorial policies for medium and long-term regional development in order to empower regionalization and to overcome obstacles to the access to healthcare services in Brazil.

Job satisfaction and discrepancies between social and biological timing

The discrepancies between social and biological timing are reflected in shift workers' well-being. The aim of this study was to verify the association between job satisfaction and chronotype among day and night nursing personnel. Several variables, including seniority at the hospital and, in the same shift, sleep duration, quality of sleep, sleepiness and willingness to change sleep timing were also analyzed. Chronotype was calculated by using the morningness-eveningness questionnaire. We studied 514 nursing professionals from a public university hospital. Among the day workers, the higher the morningness, the more the workers were satisfied with their job. In contrast, among night workers, job satisfaction was associated with sleep quality and seniority at the hospital but not with chronotype. Our results suggest that an agreement between work schedule and chronotype may help to increase job satisfaction among diurnal workers.

Repertoire, Genealogy and Genomic Organization of Cruzipain and Homologous Genes in Trypanosoma cruzi, T. cruzi-Like and Other Trypanosome Species

Trypanosoma cruzi, the agent of Chagas disease, is a complex of genetically diverse isolates highly phylogenetically related to T. cruzi-like species, Trypanosoma cruzi marinkellei and Trypanosoma dionisii, all sharing morphology of blood and culture forms and development within cells. However, they differ in hosts, vectors and pathogenicity: T. cruzi is a human pathogen infective to virtually all mammals whilst the other two species are non-pathogenic and bat restricted. Previous studies suggest that variations in expression levels and genetic diversity of cruzipain, the major isoform of cathepsin L-like (CATL) enzymes of T. cruzi, correlate with levels of cellular invasion, differentiation, virulence and pathogenicity of distinct strains. In this study, we compared 80 sequences of genes encoding cruzipain from 25 T. cruzi isolates representative of all discrete typing units (DTUs TcI-TcVI) and the new genotype Tcbat and 10 sequences of homologous genes from other species. The catalytic domain repertoires diverged according to DTUs and trypanosome species. Relatively homogeneous sequences are found within and among isolates of the same DTU except TcV and TcVI, which displayed sequences unique or identical to those of TcII and TcIII, supporting their origin from the hybridization between these two DTUs. In network genealogies, sequences from T. cruzi clustered tightly together and closer to T. c. marinkellei than to T. dionisii and largely differed from homologues of T. rangeli and T. b. brucei. Here, analysis of isolates representative of the overall biological and genetic diversity of T. cruzi and closest T. cruzi-like species evidenced DTU- and species-specific polymorphisms corroborating phylogenetic relationships inferred with other genes. Comparison of both phylogenetically close and distant trypanosomes is valuable to understand host-parasite interactions, virulence and pathogenicity. Our findings corroborate cruzipain as valuable target for drugs, vaccine, diagnostic and genotyping approaches.

Morbidity among nursing personnel and its association with working conditions and work organization

Introduction: Work organization patterns and working conditions experienced by nursing personnel in the hospital settings may be associated to increased morbidity among these health workers. Aim: To estimate the prevalence and factors associated with self-reported diseases among nursing personnel at the emergency hospital in Rio Branco/ State of Acre, Brazil. Methods: A cross-sectional study was conducted involving 272 participants who answered a questionnaire including sociodemographic characteristics, working conditions, lifestyles, work ability, and a fatigue perception scale. The self-reported diseases in the 12 months prior to data collection were considered the dependent variable. Results: A total of 85.7% of the participants reported one or more diseases in the past 12 months. Most prevalent diseases were: musculoskeletal diseases (37.1%), digestive diseases (28.7%), mental disorders (28.3%), work injuries (27.9%), and respiratory diseases (26.8%). The following significant variables remained in the final model: high work demands (OR 2.69), reported fatigue (OR 3.59), night work (OR 6.55) and being a technician or nursing assistant (OR 4.23). Conclusions: Variables related to working conditions and work organization were associated with the occurrence of reported diseases among nursing professionals. Health promotion measures at work require a comprehensive approach including the working conditions and the work organization.

La "responsabilità sociale" dell'imprenditore negli ambienti cattolici lombardi dagli anni Trenta alla Ricostruzione

My research focuses on the mentality of catholic entrepreneurs and managers in Italy between the 1930's and the 1950's. The main source of my study is the archive of an organization called Unione Cristiana Imprenditori Dirigenti [Christian Entrepreneurs and Managers Association], which was founded in Milan in 1945 with the pedagogic intent to foster higher moral standards and social responsibility in the milieux of catholic entrepreneurs, in the spirit of the Social Doctrine of the Church. This experience was set in the social and political context of the Italian post-war years, but it was also rooted in the debate – started during the 1930s - on the rise of a new catholic leadership in society.
