Prevenção primária em psiquiatria: possibilidade ou utopia?
Authors: Machado Leonardo , Souza Camila Twany Nunes de , Cantilino Amaury
Published: July 2017

A psiquiatria é o ramo da medicina que se dedica ao estudo dos transtornos mentais, com o objetivo de diagnosticar, classificar, tratar e prevenir. Entretanto, diferentemente das outras áreas médicas, pensar em uma abordagem preventiva na psiquiatria é algo relativamente novo. Somente na década de 1970 é que começaram a ser implementadas as primeiras iniciativas de prevenção em saúde mental. Os primeiros esforços tiveram como foco indivíduos em risco para psicose. Nas últimas décadas, os principais avanços no campo preventivo dentro da psiquiatria se deram nas prevenções secundária e terciária. Entretanto, seria possível fazer prevenção primária em psiquiatria? As publicações parecem dizer que sim. Cerca de 1.000 estudos controlados já foram publicados sobre prevenção primária em psiquiatria, sendo a maior parte em crianças e adolescentes. Em geral, esses estudos mostraram a capacidade da prevenção de reduzir fatores de riscos para adoecimento psíquico, de fortalecer fatores protetores e de gerar um impacto econômico positivo. Além disso, embora em um número muito menor, esses trabalhos conseguiram demonstrar que estratégias preventivas também são capazes de diminuir a incidência de transtornos mentais comuns, como depressão e transtornos de ansiedade.

Published: July 2017

Os dados da literatura são unânimes em confirmar os malefícios do fumo na população geral e, sobretudo, em gestantes. Fumo na gestação é preditor para resultados adversos no nascimento, como nascimento prematuro e baixo peso ao nascer, bem como para maior mortalidade fetal e infantil. A abstinência do cigarro sempre deve ser estimulada em gestantes. Para maior sucesso do tratamento, devem-se considerar as vulnerabilidades sociais, as doenças associadas (principalmente depressão e ansiedade), o nível de maturidade emocional, o desejo pela gestação e as incertezas sobre o futuro. O objetivo deste artigo é identificar as gestantes que estão mais propensas a permanecer fumando durante a gestação, orientar sobre a abordagem médica, avaliando se há tratamentos seguros durante a gravidez e qual a melhor modalidade terapêutica a ser oferecida. Atualmente, a terapia comportamental, em especial a terapia cognitiva comportamental, é o melhor tratamento para a abstinência do cigarro, para pacientes gestantes ou não. Em caso de dependência grave de nicotina, é necessária a introdução de medicações. A medicação mais usada é a bupropiona, apesar de os estudos ainda não garantirem a sua segurança em relação ao feto. Na prática, não se observam complicações nas gestantes e nos fetos.

Published: July 2017

Situações envolvendo assédio moral nas empresas podem ser um dos causadores de sofrimento psíquico e, por vezes, ocasionam transtornos mentais que podem repercutir no afastamento do trabalho. De acordo com a Previdência Social, a concessão de auxílios-doença por desequilíbrio mental vem crescendo e poderá ser, em breve, a principal causa de afastamento dos trabalhadores. Este estudo tem por base, principalmente, a teoria de Christophe Dejours, que diz que o trabalho pode causar sofrimento e adoecimento aos trabalhadores. O objetivo deste artigo é apresentar um breve resumo da temática do assédio moral aplicado ao contexto do trabalho, do sofrimento psíquico decorrente deste, além de mostrar o processo de adoecimento e as consequências do assédio moral. Com abordagem qualitativa, a metodologia utilizada foi o estudo de caso, através da análise de conteúdo dos relatos de uma trabalhadora vítima de assédio moral no trabalho, onde foram incluídos os pormenores da relação de trabalho e o diagnóstico dos médicos.

Published: July 2017

Die Regeneration komplexer Investitionsgüter (maintenance, repair and overhaul) ist durch eine hohe Unsicherheit bzgl. der auftretenden Schäden und den daraus resultierenden abzuarbeitenden Arbeitsinhalten geprägt. Zusätzlich unterliegen Regenerationsprozesse hohen logistischen Anforderungen, die sich insbesondere in der vom Kunden geforderten hohen Termintreue widerspiegeln. Zur Gewährleistung einer hohen Termintreue müssen alle beteiligten Prozesse der Regeneration aufeinander abgestimmt sein. Dafür muss insbesondere die Remontage rechtzeitig mit den für einen Auftrag notwendigen Komponenten versorgt werden. Die Wahl der Reihenfolgeregel im Repair-Bereich sowie die Dimensionierung des sogenannten Poolbestands bilden hierbei zwei wichtige Einflussgrößen. In diesem Beitrag werden die Auswirkungen dieser zwei Gestaltungsoptionen auf die Fehlteilsituation in der Remontage diskutiert und Simulationsergebnisse bzgl. der Auswirkungen auf die Fehlteilsituation vorgestellt.*)

Studies on Emulsification Properties of Glycolipids Biosurfactants
Authors: Patil Harshada , Pratap Amit
Published: July 2017

Microbial biosurfactants consists of hydrophilic and hydrophobic moieties in its structure and are produced by microorganisms. Glycolipid class of biosurfactants has wide range of surface and interfacial properties. The emulsification activity and emulsion stability of the Glycolipids Trehalose lipids (THL), Mannosylerrythritol lipids (MEL), Sophorolipids (SL) and Rhamnolipids (RL) were investigated using liquid paraffin (hydrocarbon source) and sunflower oil (vegetable source) as hydrophobic source by UV spectroscopy. Emulsification activity and stability are in the order THL > MEL > SL > RL. The stability as a function of the temperature in the range of 20 °C – 80 °C is in order THL > SL > MEL > RL. The effect of pH was studied using buffers of acidic and basic pH. It was observed that RL and SL had excellent emulsification activity at pH 8 while the activity of trehalose lipids and mannosylerrythritol lipids was not affected by pH. Similar effect of various concentrations of salt (NaCl) was studied; THL and MEL emulsion were very resistant to concentration of salt but the stability of SL and RL emulsion decreased with increased salt concentration. Average droplet diameter of emulsion and the polydispersity index were determined by dynamic light scattering. The emulsions of THL and SL have smallest droplet diameter of 422 nm and 625 nm, while emulsions of MEL and RL have a droplet size of 1923 nm and 2245 nm respectively. Emulsions of all investigatesd glycolipid surfactants had good polydispersity index and negative zeta potential, suggesting their possible applications in pharmaceutical, cosmetics, industrial and environmental techniques.

Analytic and Diagnostic Performances of Human Papillomavirus E6/E7 mRNA Test on up-to 11-Year-Old Liquid-Based Cervical Samples. A Biobank-Based Longitudinal Study
Authors: Zappacosta Roberta , Sablone Francesca , Pansa Lucia , Buca Davide , Buca Danilo , Rosini Sandra
Published: July 2017

Human Papillomavirus (HPV) E6/E7 mRNA test demonstrated high specificity in detecting HPV infections, but studies assessing its efficacy in terms of cancer risk stratification are lacking. Follow-up studies are arduous and expensive. Biobank would be the answer to the problem, although data investigating the effects of long-term storage on RNA preservation are still needed. We addressed these issues by retrieving 202 residual liquid-based cervical specimens, collected from 149 women attending cervical cancer screening during the years 2001–2012. Samples were stored in Adriatic Biobank at room temperature and without any handing. After calculation of RNA yield and purity, E6/E7 mRNA test was retrospectively performed on each samples, to assess analytic and diagnostic performances. Using automated extraction procedures, RNA of good quantity and quality was obtained. The mean value of RNA concentration was 27.5 ng/μL. The mean A260/A280 ratio was 2.1. An invalid mRNA test result was found in 11.9% of the specimens. Neither RNA integrity, nor analytic performances of mRNA test were influenced by the year of sample collection. In total, 62.4% of the specimens tested as mRNA positive; among these, 89.2% were CIN2+. E6/E7 mRNA was detected in all Squamous Cervical Cancer (SCC) cases. Percentage of positive samples increased with the severity of histological diagnosis. mRNA testing, showing specificity and predictive values of 75.6% and 84.4%, respectively, significantly improved the corresponding values for DNA testing. Thus, the reflex mRNA test was demonstrated to be suitable to triage women with persistent cervical lesions. A “one sample for all” approach is possible, with practical benefits for Biobank-based long-term longitudinal studies, diseases prevention, prediction, diagnosis and treatment.
Antioxidant Activity of Essential Oil Extracted by SC-CO2 from Seeds of Trachyspermum ammi
Authors: Singh Aarti , Ahmad Anees
Published: July 2017

Bcakground: Extracts obtained from natural sources such as plants are of immense importance for humans. Methods: Therefore this study was conducted to obtain essential oil from the seeds of T. ammi by conventional and non-conventional methods. Hydrodistillation (HD), Solvent Extraction (SE), Ultrasonication (US), and Supercritical Carbon-dioxide (SC-CO2) extraction techniques were used to extract essential oil from the powdered seeds of T. ammi. A quality control method for each extracted oil was developed using HPTLC, FTIR, and GC-MS. The optimization process was carried out using fractional factorial design (FFD) under which three parameters were considered: pressure (150, 175, and 300 bar), temperature (25, 30, and 40 °C), and CO2 flow rate (5, 10, 15 g/min). Results: The yield of essential oil obtained from the HD, SE, US, and SC-CO2 methods were 1.20%, 1.82%, 2.30%, and 2.64% v/w, respectively. Antioxidant activity was determined by the DPPH and superoxide scavenging methods and the IC50 (Inhibition Concentration) values of the T. ammi oil sample were found to be 36.41 and 20.55 µg mL−1, respectively. Conclusion: The present paper reported that different extraction methods lead to different yields of essential oils and the choice of a suitable method is extremely important to obtain more preferred compounds. The yield was higher in the SC-CO2 method and it is a sustainable and green extraction technique. Many important constituents were detected in analytical techniques. Antioxidant activities carried out showed that essential oil extracted from T. ammi seeds possess significant antioxidant activity.
Strategies for Pathogen Biocontrol Using Lactic Acid Bacteria and Their Metabolites: A Focus on Meat Ecosystems and Industrial Environments
Authors: Castellano Patricia , Pérez Ibarreche Mariana , Blanco Massani Mariana , Fontana Cecilia , Vignolo Graciela
Published: July 2017

The globalization of trade and lifestyle ensure that the factors responsible for the emergence of diseases are more present than ever. Despite biotechnology advancements, meat-based foods are still under scrutiny because of the presence of pathogens, which causes a loss of consumer confidence and consequently a fall in demand. In this context, Lactic Acid Bacteria (LAB) as GRAS organisms offer an alternative for developing pathogen-free foods, particularly avoiding Listeria monocytogenes, with minimal processing and fewer additives while maintaining the foods’ sensorial characteristics. The use of LAB strains, enabling us to produce antimicrobial peptides (bacteriocins) in addition to lactic acid, with an impact on quality and safety during fermentation, processing, and/or storage of meat and ready-to-eat (RTE) meat products, constitutes a promising tool. A number of bacteriocin-based strategies including the use of bioprotective cultures, purified and/or semi-purified bacteriocins as well as their inclusion in varied packaging materials under different storage conditions, have been investigated. The application of bacteriocins as part of hurdle technology using non-thermal technologies was explored for the preservation of RTE meat products. Likewise, considering that food contamination with L. monocytogenes is a consequence of the post-processing manipulation of RTE foods, the role of bacteriocinogenic LAB in the control of biofilms formed on industrial surfaces is also discussed.

Pharmacologic Inhibition of β-Catenin With Pyrvinium Inhibits Murine and Human Models of Wilms Tumor
Authors: Polosukhina Dina , Love Harold D. , Moses Harold L. , Lee Ethan , Zent Roy , Clark Peter E.
Published: July 2017

Wilms tumor (WT) is the most common renal malignancy in children and the fourth most common pediatric solid malignancy in the US. Although the mechanisms underlying the WT biology are complex, these tumors most often demonstrate activation of the canonical Wnt/β-catenin pathway.
We and others have shown that constitutive activation of β-catenin restricted to the renal epithelium is sufficient to induce primitive renal epithelial tumors, which resemble human WT. Here we demonstrate that pharmacologic inhibition of β-catenin gene transcription with pyrvinium
inhibits tumor growth and metastatic progression in a murine model of WT. Cellular invasion is significantly inhibited in both murine WT-like and human WT cells and is accompanied by downregulation of the oncogenes Myc and Birc5 (survivin). Our studies provide proof of the concept
that the canonical Wnt/β-catenin pathway may be a novel therapeutic target in the management of WT.
Infrared Emission from Kilonovae: The Case of the Nearby Short Hard Burst GRB 160821B
Authors: Kasliwal Mansi M. , Korobkin Oleg , Lau Ryan M. , Wollaeger Ryan , Fryer Christopher L.
Published: July 2017

We present constraints on Ks-band emission from one of the nearest short hard gamma-ray bursts, GRB 160821B, at z = 0.16, at three epochs. We detect a red relativistic afterglow from the jetted emission in the first epoch but do not detect any excess kilonova emission in the second two epochs. We compare upper limits obtained with Keck I/MOSFIRE to multi-dimensional radiative transfer models of kilonovae, that employ composition-dependent nuclear heating and LTE opacities of heavy elements. We discuss eight models that combine toroidal dynamical ejecta and two types of wind and one model with dynamical ejecta only. We also discuss simple, empirical scaling laws of predicted emission as a function of ejecta mass and ejecta velocity. Our limits for GRB 160821B constrain the ejecta mass to be lower than 0.03 M
⊙ for velocities greater than 0.1 c. At the distance sensitivity range of advanced LIGO, similar ground-based observations would be sufficiently sensitive to the full range of predicted model emission including models with only dynamical ejecta. The color evolution of these models shows that I–K color spans 7–16 mag, which suggests that even relatively shallow infrared searches for kilonovae could be as constraining as optical searches.
The Threatening Magnetic and Plasma Environment of the TRAPPIST-1 Planets
Authors: Garraffo Cecilia , Drake Jeremy J. , Cohen Ofer , Alvarado-Gómez Julian D. , Moschou Sofia P.
Published: July 2017

Recently, four additional Earth-mass planets were discovered orbiting the nearby ultracool M8 dwarf, TRAPPIST-1, making a remarkable total of seven planets with equilibrium temperatures compatible with the presence of liquid water on their surface. Temperate terrestrial planets around an M-dwarf orbit close to their parent star, rendering their atmospheres vulnerable to erosion by the stellar wind and energetic electromagnetic and particle radiation. Here, we use state-of-the-art 3D magnetohydrodynamic models to simulate the wind around TRAPPIST-1 and study the conditions at each planetary orbit. All planets experience a stellar wind pressure between 103 and 105 times the solar wind pressure on Earth. All orbits pass through wind pressure changes of an order of magnitude and most planets spend a large fraction of their orbital period in the sub-Alfvénic regime. For plausible planetary magnetic field strengths, all magnetospheres are greatly compressed and undergo much more dynamic change than that of the Earth. The planetary magnetic fields connect with the stellar radial field over much of the planetary surface, allowing the direct flow of stellar wind particles onto the planetary atmosphere. These conditions could result in strong atmospheric stripping and evaporation and should be taken into account for any realistic assessment of the evolution and habitability of the TRAPPIST-1 planets.
La supervision comme danse épistémique et le jeu des destins croisés
Authors: Bruni Francesco
Published: July 2017

L’auteur traite la question de la supervision de la psychothérapie systémique relationnelle et décrit deux façons de présenter les situations cliniques lors de rencontres avec un groupe. Il met l’accent sur la construction du contexte thérapeutique et sur la danse épistémique comme rencontre relationnelle qui nécessite un ajustement mutuel constant pour partager l’expérience, ce qui conduit à se redécouvrir dans la relation d’aide. La supervision est considérée comme un jeu de destins croisés qui aide à élaborer le sens des événements et à les enrichir avec le soutien du groupe et du superviseur, dans un échange dialogique qui nous permet de ne pas nous penser sans l’autre.

Authors: Bergeaud-Blackler Florence , Kokoszka Valérie
Published: July 2017

Cet article décrit et analyse les enjeux et l’impact du travail normatif de la commission du Comité européen de normalisation « CEN 425/TC Halal food » sur la norme religieuse. Dans un premier temps, nous y interrogeons la façon dont la « machine » normative a pu étendre son intervention au domaine religieux et le trajet que le projet de norme a emprunté pour aboutir au CEN. Dans un second temps, nous analysons les principes de guidance du travail normatif et leur impact sur la production de la norme technique halal. Enfin, nous tentons de cerner les effets de la régulation économique transnationale sur l’État et sur les autorités religieuses et leur traduction sur les équilibres juridiques et politiques séculiers : soucieuse d’ouverture et de participation plurielle, la normalisation dictée par la « nouvelle approche » au moment du tournant néolibéral européen n’engendre-t-elle pas, in fine , un certain type de norme technico-religieuse que seuls les courants fondamentalistes seraient en mesure de soutenir ?
À la recherche de la signification perdue du paradoxe d’Allais
Authors: Jullien Dorian
Published: July 2017

Dans « Le paradoxe d’Allais. Comment lui rendre sa signification perdue ? », Philippe Mongin [2014] propose une image contestable, parce qu’abusivement rassurante, de la rationalité des sujets participant aux expériences de MacCrimmon et Larsson [1979]. Nous montrons cela en restituant les données des auteurs pour l’effet de conséquence commune et l’effet de rapport commun (deux paradoxes d’Allais), que Mongin assimile, bien qu’il distingue ces deux effets. Deux tendances dans les données nous conduisent à rejoindre Mongin pour conclure que ces expériences sont une source d’inspiration fructueuse pour la théorie de la décision, ce que nous illustrons brièvement par le rôle qu’elles ont joué dans l’apparition de l’utilité espérée dépendante du rang et dans le tournant interindividuel en psychologie cognitive de la décision.
Corps de femme, corps du féminin
Authors: Aloupis Panos
Published: July 2017

L’auteur, à partir du matériel d’une séance d’une patiente et de travaux analytiques freudiens et post-freudiens portant sur la sexualité féminine, propose une étude du féminin, de sa place et de sa trajectoire par rapport à l’évolution de l’appareil psychique. Élément composant dans la constitution et l’organisation de la passivité, de la régression et du masochisme, le féminin s’associe à la pulsionnalité dans son mouvement vers l’intérieur, accompagne les aléas de la féminité et construit la position féminine, inhérente à la capacité d’accueil de l’objet et, par conséquent, caractéristique de l’écoute analytique.
L’anorexique et son corps
Authors: Brusset Bernard
Published: July 2017

Anorexies mentales et boulimies sont envisagées à propos des sensations corporelles, de l’idéal, de l’alexithymie, de l’actuel à l’adolescence, de l’addiction et, enfin, de la solution anorexique, de la somatisation et du narcissisme négatif. Du point de vue métapsychologique, le partage entre fonctionnement psychique selon la première et selon la deuxième topique freudienne distingue des formes cliniques différentes, et fonde le pronostic et les modalités thérapeutiques.
Imaginaires nés des lieux hétérotopiques chez Kim Ki-duk
Authors: Lee Yun-yeong
Published: July 2017

Les espaces cinématographiques singuliers que le cinéma de Kim Ki-duk a explorés peuvent être qualifiés d’hétérotopiques. Ils sont non seulement grotesques, maussades et excentriques, mais aussi réellement situés en Corée, à savoir localisables. Une part notable du travail de ce metteur en scène consiste à repérer des hétérotopies au sein de la société coréenne, à les employer ensuite pour construire ses espaces cinématographiques, avant d’appliquer leurs particularités aux personnages, aux événements, voire aux imaginaires. Un autre lieu, le corps, qui subit chez Kim toutes les formes de violence, témoigne de la rigidité sociale mortifère. D’autres imaginaires, nés principalement des lieux hétérotopiques dans le cinéma de Kim, contestent la société coréenne, ainsi que son imaginaire typique.
Influence of ICTs on the Information Behavior of the Elderly in Nigeria
Authors: Afolayan Oluyinka Titilope
Published: July 2017

The uptake of ICTs by the elderly to fulfil their diverse information needs is ridden with unavoidable challenges militating against their full exploitation of these technologies. In view of this, this paper examined the influence of ICTs on the information behaviour of the elderly in Nigeria. The methodology adopted for this research work was purely documentary and literature search in determining the extent of the influence of ICTs on the information behaviour of the elderly in Nigeria. Specifically, the research objectives for this paper addressed the Information needs of the elderly; sources of Information frequently consulted by the elderly; types of ICTs often used by the elderly; factors challenging the elderly in meeting their information needs, seeking and use using ICTs. Findings revealed that the information needs of the elderly are diverse, differ from person to person. The elderly was equally faced with personal challenges such as old age syndromes covering anxieties, disabilities, nervousness, and lack of good eyesight that affected their ICT usage.
The Impact of Personal and Positional Powers on Knowledge Management Systems
Authors: Scovetta Vincent
Published: July 2017

The importance of Knowledge Management System (KMS) to an evolving knowledge economy has been reported in the literature for many years. This importance, in part, is due to KMS's ability to foster positive organizational value by increase its competitive edge. Organizational leadership has repeatedly appeared in the literature as a reliable determinant of KMS success. While researchers have identified many of the critical success factors that influence that success, the subconstructs of leader power remains elusive. This study was able to empirically demonstrate the predominate construct of Expert and Reward powers were positive, significant, and consistent across all KMS constructs (leadership commitment to KMS, knowledge content quality, knowledge system quality, and knowledge use). Legitimate power demonstrated negative influences on various KMS constructs. Information powers had varying degrees of success while Coercive power was not statistically significant.
Beliefs about the cause of schizophrenia among caregivers in Midwestern Nigeria
Authors: Igberase Osayi , Okogbenin Esther
Published: July 2017

Schizophrenia is a devastating illness with a chronic and relapsing course. While Western countries may endorse, biological and psychosocial causes more commonly than supernatural causes, non-western cultures like Nigeria in contrast, tend to endorse supernatural causes. Belief in supernatural causes has been reported to have consequences for treatment seeking behavior. This study aimed to examine the causes of schizophrenia reported by family members of outpatients with schizophrenia in a neuropsychiatric hospital in Midwestern Nigeria. In this study, we recruited a convenient sample of 200 consecutive caregivers of patients visiting the outpatient department of the Psychiatric Hospital, Benin City, Nigeria. These primary caregivers were unpaid relatives who provided support to patients. The patients were service users who fulfilled the diagnostic criteria of the International Classification of Disease [ICD-10; World Health Organization 1993] for schizophrenia and had been on treatment for at least two years. Majority (72.0%) of caregivers endorsed supernatural causes as most important in the etiology of schizophrenia, while 28.0% endorsed natural causes. Every participant without formal education endorsed supernatural attribution. In our study, it was evident that participants embraced multiple causal attributions for schizophrenia.
Stokes Flow of Viscous Fluid Past a Micropolar Fluid Spheroid
Authors: Prasad M. Krishna , Kaur Manpreet
Published: July 2017

The Stokes axisymmetric flow of an incompressible viscous fluid past a micropolar fluid spheroid whose shape deviates slightly from that of a sphere is studied analytically. The boundary conditions used are the vanishing of the normal velocities, the continuity of the tangential velocities, continuity of shear stresses and spin-vorticity relation at the surface of the spheroid. The hydrodynamic drag force acting on the fluid spheroid is calculated. An exact solution of the problem is obtained to the first order in the small parameter characterizing the deformation. It is observed that due to increase spin parameter value, the drag coefficient decreases. Well known results are deduced and comparisons are made with classical viscous fluid and micropolar fluid.

Pan-africanismo, negritude e teatro experimental do negro
Authors: Munanga Kabengele
Published: July 2017

http://dx.doi.org/10.5007/2175-8034.2016v18n1p109Pretende-se neste texto, que integra o conjunto de trabalhos em homenagem ao intelectual negro Guerreiro Ramos, analisar de modo sintético três temas interligados que fizeram parte do pensamento e da linha de ação em busca da libertação do negro. Trata-se do pan-africanismo, da Negritude e do Teatro Experimental do Negro brasileiro. O primeiro nasceu nos Estados Unidos e nas Antilhas Britânicas, em 1900; o segundo nasceu em Paris, no Quartier Latin por volta de 1935; e o terceiro, no Brasil, em 1944. Apesar de terem nascido em épocas e em espaços geográficos diferentes, os três movimentos convergem como discursos e atitudes intelectuais e políticos em defesa da libertação política do negro da diáspora e do continente africano; do reconhecimento de sua história, de sua cultura, de sua identidade; de sua plena humanidade e de uas contribuições na história da humanidade, assim como nos países das Américas, onde os negros foram deportados e escravizados. Guerreiro Ramos participou da construção do Teatro Experimental do Negro em companhia de Abdias de Nascimento, juntando suas vozes às dos intelectuais negros do Pan-africanismo e da negritude num movimento de ação em busca da inclusão do Negro no Brasil.
Ensaios críticos, vanguarda e intelectualidade – guerreiro Ramos, o não contemporizador
Authors: Antelo Raul
Published: July 2017

http://dx.doi.org/10.5007/2175-8034.2016v18n1p15Quais foram as circunstâncias históricas e os guias intelectuais que forneceram a Guerreiro Ramos tanto a força para sua crítica da política cultural quanto seus constantes apelos à ação? O propósito principal deste texto é situar as ideias de Guerreiro no contexto dos argumentos intelectuais de sua época. Tentamos iluminar a relação entre sua incipiente obsessão com o pensamento de Hegel e Nietzsche e seus trabalhos sociais derradeiros.
Formas de alocação de recursos no Brasil: elementos analíticos inescusáveis, segundo Guerreiro Ramos
Authors: Heidemann Francisco Grabiel
Published: July 2017

http://dx.doi.org/10.5007/2175-8034.2016v18n1p187Nos anos de 1978, 1979 e 1981, o professor Alberto Guerreiro Ramos, que até então vivia exilado nos EUA, escreveu 24 artigos, publicados no Jornal do Brasil, do Rio, numa primeira iniciativa de reaproximação com a sociedade brasileira. A temática central dos artigos versou sobre as formas ou arranjos brasileiros de alocação de recursos, que se baseavam então exclusivamente no modelo de livre mercado (economia política)e, assim, ignoravam os elementos institucionais que marcaram as formas históricas de alocação vigentes em toda a história anterior à assim chamada revolução industrial. Nos artigos, Guerreiro Ramos resgatou elementos essenciais para a discussão sobre o tema da alocação, inclusive criticando a visão tacanha dos policy makers e governantes brasileiros atuantes, que acreditavam de forma pia e ingênua que o mercado era um modelo superior, exclusivo e único a orientar o governo em suas políticas de desenvolvimento do país. No presente texto,tangenciam-se os artigos de Ramos, para destacar os elementos analíticos que ele julgava ineludíveis e indispensáveis a um debate correto, profícuo e honesto sobre as formas alternativas de alocação de recursos e as relações de complementaridade entre elas numa sociedade como a brasileira, valendo-se sempre do mercado como sistema de referência.
