Microcrédito emancipatório no nordeste do Brasil? : estudo de caso do Crediamigo Comunidade nos municípios de Caucaia-Ce e Maranguape-Ce

This piece of work consists in a study case of Crediamigo Comunidade, a product from the portfolio of Crediamigo Program of Banco do Nordeste, that uses the methodology of the Comunitary Banks in the concession of low amount loan to poor communities. The main question consists to understand how the Crediamigo Comunidade is characterized faced to the conflict of emancipatory versus liberal paradigms, that exists in the microcredit area. The main objective will analyze how the mechanisms: social capital, empowerment, formation to credit education and better conditions for economic and social issues promoted in the specific objectives of this product, before the dipute between these paradigms. The method adopted analyzed, in a longitudinal perspective, the three years of the product s existence (jun/2005 to jul 2008). Primary and secondary data made possible to identify qualitatively, emancipatory and non emancipatory attributes in the actions and results of Crediamigo Comunidade. It is concluded that the Crediamigo Comunidade works in a liberal logic of the Crediamigo Program, consequently, his focus is not in the emancipation of the poorest clients. The empowerment is individual and not communitary or Freiriano ; the social capital relations enlarges itself in its bounding and bridging ties, but not in its linkage ties, to have access to politic actors and consequently communitary strengthen. All the formation in the Crediamigo is strictly commercial. These characteristics happen by the liberal paradigm in the Crediamigo management and of all of its products, including the Crediamigo Comunidade

Abordagens pedagógicas na formação de enfermeiros : compreensão de docentes de enfermagem

In the new world order is notorious changes in social, ethical, economical and political aspects in the society, which reach incisively higher education, requiring a number of modifications and a new vision in nursing education, in order to meet the demands of the Unique Health System. Thus, the Higher Education Institutes (HEI) and teachers are invited to face new challenges and reflect on their practices, using pedagogical approaches and innovative methodologies to meet the requirements of a globalized society. This study has as an objective to analyze the perspective of teachers in what concern the pedagogical approaches used in nursing education and to identify pedagogical approaches utilized by teachers in nursing education. This is a field research of exploratory kind, descriptive, of quantitative approach. The search was conducted at the Department of Nursing of the Federal University of Rio Grande do Norte UFRN, based in the city of Natal. The population consisted of forty-six teachers. From this population was selected a sample of twenty teachers. Data collection occurred from August to September 2011, through the utilization of the technique of interview and questionnaire. The obtained data were analyzed in two moments. In the first moment, was carried out the quantitative analysis that refers to the obtained data through the interview technique, methodological procedures were submitted to the content analysis proposed by Bardin. On the second moment, concerning the quantitative analysis of the questionnaires applied to the teachers and of the identification data, which were digitized and transferred to a spreadsheet electronic of Microsoft Excel XP, tabulated and organized into tables, containing their relative and absolute frequencies. It is worth mentioning that were respected the aspects of the CNS Resolution 196/96. With regard to the characteristics of research participants, 20% were male; with a degree of titration of 55% doctorates; regarding time of service there was a greater representation from 15 to 45 years, with 45%. The results showed that 90% of teachers who participated in the research have an appropriate understanding of non-critical pedagogical approaches, only 10% had an inadequate understanding. However, 70% of teachers, despite having an adequate understanding, reported difficulties when attempting to implement these pedagogies. Most teachers, with representability of 80% consider the non-critical pedagogies relevant in nursing education, as well as critical pedagogies, being represented by 95% of teachers. It was concluded that both critical and non-critical pedagogies are in teachers practice of undergraduate nursing education. It feels like a moment of transition, since the presence of new ways of teaching as a part of this educational context, with educational models that give value to scientific, ethical and personal aspects in the educational process. The research contains limitations, however highlights the contribution of new possibilities for action, reflection on the context of performance, maximizing the pedagogical skills necessary to conduct teaching process, in line with the new educational paradigm of higher education

Serviço Social e Política: uma análise da participação dos assistentes sociais no Conselho Regional de Serviço Social 14ª região

This paper analyzes the political participation of Social Workers at the Social Service Regional Council Region 14th. The theoretical and methodological framework of this investigation has as its perspective the totality of social life and its determining relations within the object of study. To the production, analysis and collecting of data it was used a qualitative approach considering a bibliographical and documental research as well as a series of twelve interviews with 2005-2008 and 2008-2011 managing counselors of CRESS/RN. It was also used the data obtained from other special interviews held with the social workers in the period between 2007 and 2008. The results of this study allow and affirm the political dimension of Caseworkers and the CRESS/RN as a space of political activity with opportunities for effective and collective elaboration of strategies in order to reach the fulfillment of the ethical and professional policy of the Social Work. From a historical viewpoint, the beginning of this process is marked by the struggle for democracy, the end of military dictatorship, the establishment of the State of Human Rights. The Democratization of the so called Federal Council of Social Workers and its Regional Councils of Social Workers, CFAS / CRAS, respectively, area a result of the participation of the category in an effort to fight for democratization in Brazil. The objective of this research, so, is to understand which the socio-historical determinants are, that focus objectively and subjectively in the demobilization of social workers in CRESS Region 14th - in the contemporary and historical context. Among the results obtained we identified the ignorance of some professional workers and also of some advisors, regarding the existence and the role of the Council, as well as the commercialization of Education that compromises the quality of the professional training in its theoretical and methodological, ethical and political dimensions. According to our understanding, this shows a the presence of a non-critical professional profile based on a false reality, on the precariousness of employment contracts which undermine the political organization and submit the worker to various social exploring mechanisms such as double shift and ultimately the fragility of the management of the Regional Council -, as a consequence of the offensive capitalist system that ideologically invests to stop the political organization founded in a critical and democratic perspective. The low participation of some advisors and, in general, the category in CRESS / RN, despite its objective conditions, is a reality and it is presented to us as a challenge to future managements and policy consolidation to society. Inasmuch as the category intends to guarantee the high quality of its social workers, the demands of future counselors, their skills and abilities in dealing with regulatory issues, administrative policies that pervade the everyday life of CRESS / RN are necessary

Influence of Bioactive Glass and/or Acellular Dermal Matrix on Bone Healing of Surgically Created Defects in Rat Tibiae: A Histological and Histometric Study

The purpose of this study was to histologically analyze the influence of bioactive glass and/or acellular dermal matrix on bone healing in surgically created defects in the tibiae of 64 rats (Rattus norvegicus, albinus, Wistar). Materials and Methods: A 4-mm X 3-mm unicortical defect was created on the anterolateral surface of the tibia. Animals were divided into 4 groups: C, control; BG, the defect was filled with bioactive glass; ADM, the defect was covered with acellular dermal matrix; and BG/ADM, the defect was filled with bioactive glass and covered with acellular dermal matrix. Animals were sacrificed at 10 or 30 days postoperatively, and the specimens were removed for histologic processing. The formation of new bone in the cortical area of the defect was evaluated histomorphometrically. Results: At 10 and 30 days postoperatively, groups C (39.65% +/- 5.63% / 63.34% +/- 5.22%) and ADM (38.12% +/- 5.53 / 58.96% +/- 7.05%) presented a larger amount of bone formation compared to the other groups (P<.05). In the same periods, groups BG (13.10% +/- 6.29% / 29.5% +/- 5.56%) and BG/ADM (20.72% +/- 8.31% / 24.19% +/- 6.69%) exhibited statistically similar new bone formation. However, unlike the other groups, group BG/ADM did not present a significant increase in bone formation between the 2 time points. Conclusion: Based on these results, it can be concluded that all of the materials used in this study delayed bone healing in non-critical-size defects. INT J ORAL MAXILLOFAC IMPLANTS 2008;23:811-817

A formação do professor de educação física no Pará: o que revela a história do currículo do curso de educação física da Universidade Estadual do Pará?

Esta pesquisa tem como objetivo analisar a história do currículo do curso de formação de professores de Educação Física da Universidade do Estado do Pará, nos anos de 1970 a 2007. Utilizou-se, como método de trabalho, a pesquisa documental a partir da análise dos regimentos, das matrizes curriculares e do Projeto Político Pedagógico (PPP) de 1999 do Curso de Educação Física da Universidade do Estado do Pará, da resolução do Conselho Federal de Educação n 69/1969, que determinava o currículo mínimo, criava a licenciatura em Educação Física e mantinha o técnico desportivo; da Resolução CFE n 03/87, que preconizava a formação em licenciatura plena e/ou bacharelado; da Resolução CNE/CES n 07/2004, que institui as Diretrizes Curriculares para os cursos de Graduação em Educação Física; da Resolução n 01/2002, que trata das Diretrizes Curriculares para os cursos de formação de professores de Educação Básica em nível superior com licenciatura plena; e da Resolução n 02/2002, que institui a duração e a carga horária dos cursos de formação de professores de Educação Básica em nível superior. Conclui-se que o curso, através de seus currículos, apresenta antes do PPP 1999, uma concepção de curso desportivizado e um perfil de profissional compatível com o de técnico desportivo, acrítico, ahistórico e, após o PPP 1999, adquire uma outra concepção, direcionada para a docência, expressa no trabalho pedagógico em diferentes campos de trabalho, evidenciando um perfil de profissional com caráter ampliado, generalista, humanista, crítico e reflexivo, pautado em princípios éticos, políticos, pedagógicos e com base no rigor científico.

Aplicação do algoritmo Rough Sets em um Data Warehouse

This Project aims to develop methods for data classification in a Data Warehouse for decision-making purposes. We also have as another goal the reduction of an attribute set in a Data Warehouse, in which a given reduced set is capable of keeping the same properties of the original one. Once we achieve a reduced set, we have a smaller computational cost of processing, we are able to identify non-relevant attributes to certain kinds of situations, and finally we are also able to recognize patterns in the database that will help us to take decisions. In order to achieve these main objectives, it will be implemented the Rough Sets algorithm. We chose PostgreSQL as our data base management system due to its efficiency, consolidation and finally, it’s an open-source system (free distribution)

Autonomic control of post-air-breathing tachycardia in Clarias gariepinus

The African catfish (Clarias gariepinus) is a teleost with bimodal respiration that utilizes a paired suprabranchial chamber located in the gill cavity as an air-breathing organ. Like all air-breathing fishes studied to date, the African catfish exhibits pronounced changes in heart rate (f H) that are associated with air-breathing events. We acquired f H, gill-breathing frequency (f G) and air-breathing frequency (f AB) in situations that require or do not require air breathing (during normoxia and hypoxia), and we assessed the autonomic control of post-air-breathing tachycardia using an infusion of the β-adrenergic antagonist propranolol and the muscarinic cholinergic antagonist atropine. During normoxia, C. gariepinus presented low f AB (1.85 ± 0.73 AB h−1) and a constant f G (43.16 ± 1.74 breaths min−1). During non-critical hypoxia (PO2 = 60 mmHg), f AB in the African catfish increased to 5.42 ± 1.19 AB h−1 and f G decreased to 39.12 ± 1.58 breaths min−1. During critical hypoxia (PO2 = 20 mmHg), f AB increased to 7.4 ± 1.39 AB h−1 and f G decreased to 34.97 ± 1.78 breaths min−1. These results were expected for a facultative air breather. Each air breath (AB) was followed by a brief but significant tachycardia, which in the critical hypoxia trials, reached a maximum of 143 % of the pre-AB f H values of untreated animals. Pharmacological blockade allowed the calculation of cardiac autonomic tones, which showed that post-AB tachycardia is predominantly regulated by the parasympathetic subdivision of the autonomic nervous system.

The role of empirical research in the study of complex forms of governance in agroindustrial systems

The growing complexity of supply chains poses new challenges for Agricultural Research Centers and statistical agencies. The aim of this perspective paper is to discuss the role of empirical research in understanding the complex forms of governance in agribusiness. The authors argue that there are three fundamental levels of analysis: (i) the basic structure of the market, (ii) the formal contractual arrangements that govern relations within the agroindustrial system and (iii) the transactional dimensions governed by non-contractual means. The case of the agrochemical industry in Brazil illustrates how traditional analyses that only address market structure are insufficient to fully explain the agricultural sector and its supply chain. The article concludes by suggesting some indicators which could be collected by statistical agencies to improve understanding of the complex relationships among agribusiness segments. In doing so, the paper seeks to minimize costs and to enable a better formulation of public and private policies.

Analisi critica di modelli previsionali per le frane in Emilia Romagna

Questa tesi di dottorato è inserita nell’ambito della convenzione tra ARPA_SIMC (che è l’Ente finanziatore), l’Agenzia Regionale di Protezione Civile ed il Dipartimento di Scienze della Terra e Geologico - Ambientali dell’Ateneo di Bologna. L’obiettivo principale è la determinazione di possibili soglie pluviometriche di innesco per i fenomeni franosi in Emilia Romagna che possano essere utilizzate come strumento di supporto previsionale in sala operativa di Protezione Civile. In un contesto geologico così complesso, un approccio empirico tradizionale non è sufficiente per discriminare in modo univoco tra eventi meteo innescanti e non, ed in generale la distribuzione dei dati appare troppo dispersa per poter tracciare una soglia statisticamente significativa. È stato quindi deciso di applicare il rigoroso approccio statistico Bayesiano, innovativo poiché calcola la probabilità di frana dato un certo evento di pioggia (P(A|B)) , considerando non solo le precipitazioni innescanti frane (quindi la probabilità condizionata di avere un certo evento di precipitazione data l’occorrenza di frana, P(B|A)), ma anche le precipitazioni non innescanti (quindi la probabilità a priori di un evento di pioggia, P(A)). L’approccio Bayesiano è stato applicato all’intervallo temporale compreso tra il 1939 ed il 2009. Le isolinee di probabilità ottenute minimizzano i falsi allarmi e sono facilmente implementabili in un sistema di allertamento regionale, ma possono presentare limiti previsionali per fenomeni non rappresentati nel dataset storico o che avvengono in condizioni anomale. Ne sono esempio le frane superficiali con evoluzione in debris flows, estremamente rare negli ultimi 70 anni, ma con frequenza recentemente in aumento. Si è cercato di affrontare questo problema testando la variabilità previsionale di alcuni modelli fisicamente basati appositamente sviluppati a questo scopo, tra cui X – SLIP (Montrasio et al., 1998), SHALSTAB (SHALlow STABility model, Montgomery & Dietrich, 1994), Iverson (2000), TRIGRS 1.0 (Baum et al., 2002), TRIGRS 2.0 (Baum et al., 2008).

The burnout syndrome among nurses in an urban acute care hospital

Three hundred fifty-four registered nurses from an urban acute care hospital were examined through self-report questionnaires. Nurses from trauma care, critical care and non-critical care nursing specialties participated in the study. The study focuses were (1) whether sociodemographic characteristics were significantly related to burnout; (2) what was the prevalence estimate of burnout among the population; (3) whether burnout levels differed depending upon nursing specialties and; (4) whether burnout as related to nursing stress, work environment, and work relations was mediated by sociodemographic characteristics.^ Race, age, marital status, education, seniority, rank, nursing education, and birthplace were significantly related to one or more aspects of burnout in the total population. With emotional exhaustion alone the prevalence of burnout was 62%. Using emotional exhaustion and depersonalization combined with reduced sense of personal accomplishment as a measure of burnout, thirty-four percent of the nurses were either in the pre-burnout phase or burned out. The relative importance of sociodemographic characteristics indicated that experience and race were highly significant risk factors.^ Burnout levels differed significantly depending upon nursing specialty. Specifically, levels of emotional exhaustion and depersonalization differed significantly between trauma care and critical care, and trauma care and non-critical care. Personal accomplishment did not differ depending upon nursing specialty. Critical care nurses did not differ significantly from non-critical care nurses on aspect of burnout.^ Race, marital status, education, seniority and rank were significant mediators of emotional exhaustion and depersonalization. The study offers possible explanations for the mediating effect of sociodemographic characteristics on nursing stress, work environment, work relations, emotional exhaustion and depersonalization. ^

Corticosteroid treatment for community-acquired pneumonia--the STEP trial: study protocol for a randomized controlled trial

BACKGROUND Community-acquired pneumonia (CAP) is the third-leading infectious cause of death worldwide. The standard treatment of CAP has not changed for the past fifty years and its mortality and morbidity remain high despite adequate antimicrobial treatment. Systemic corticosteroids have anti-inflammatory effects and are therefore discussed as adjunct treatment for CAP. Available studies show controversial results, and the question about benefits and harms of adjunct corticosteroid therapy has not been conclusively resolved, particularly in the non-critical care setting. METHODS/DESIGN This randomized multicenter study compares a treatment with 7 days of prednisone 50 mg with placebo in adult patients hospitalized with CAP independent of severity. Patients are screened and enrolled within the first 36 hours of presentation after written informed consent is obtained. The primary endpoint will be time to clinical stability, which is assessed every 12 hours during hospitalization. Secondary endpoints will be, among others, all-cause mortality within 30 and 180 days, ICU stay, duration of antibiotic treatment, disease activity scores, side effects and complications, value of adrenal function testing and prognostic hormonal and inflammatory biomarkers to predict outcome and treatment response to corticosteroids. Eight hundred included patients will provide an 85% power for the intention-to-treat analysis of the primary endpoint. DISCUSSION This largest to date double-blind placebo-controlled multicenter trial investigates the effect of adjunct glucocorticoids in 800 patients with CAP requiring hospitalization. It aims to give conclusive answers about benefits and risks of corticosteroid treatment in CAP. The inclusion of less severe CAP patients will be expected to lead to a relatively low mortality rate and survival benefit might not be shown. However, our study has adequate power for the clinically relevant endpoint of clinical stability. Due to discontinuing glucocorticoids without tapering after seven days, we limit duration of glucocorticoid exposition, which may reduce possible side effects. TRIAL REGISTRATION 7 September 2009 on ClinicalTrials.gov: NCT00973154.

Patients' preferences for a prostate cancer consultation, a discrete choice experiment

Four basic medical decision making models are commonly discussed in the literature in reference to physician-patient interactions. All fall short in their attempt to capture the nuances of physician-patient interactions, and none satisfactorily address patients' preferences for communication and other attributes of care. Prostate cancer consultations are one setting where preferences matter and are likely to vary among patients. Fortunately, discrete choice experiments are capable of casting light on patients' preferences for communication and other attributes of value that make up a consultation before the consultation occurs, which is crucial if patients are to derive the most utility from the process of reaching a decision as well as the decision itself. The results of my dissertation provide strong support to the notion that patients, at least in the hypothetical setting of a DCE, have identifiable preferences for the attributes of a prostate cancer consultation and that those preferences are capable of being elicited before a consultation takes place. Further, patients' willingness-to-pay for the non-cost attributes of the consultation is surprisingly robust to a variety of individual level variables of interest. ^
