MTQ ; Antara Seni Membaca Alquran dan Politik Akomodasionis Pemerintah terhadap Umat Islam
Authors: Handayana Sri , Rezi Muhamad
Published: March 2019

MTQ is a manifestation of Islamic culture and is constantly evolving. MTQ is also one of the government policies related to Muslims and even seems to accommodate the interests of Muslims. The author believes that MTQ can be investigated from various aspects. If viewed from a religious perspective, MTQ is one way to improve spiritual life. If viewed from an economic standpoint, MTQ can support economic development through exhibitions or bazaars held in the main arena. Whereas if it is highlighted with the political glasses of MTQ, perhaps on the one hand the government is accommodating towards Muslims. This paper attempts to describe MTQ and its ins and outs, then also attempts to analyze MTQ as a form of aesthetic reception of the Qur'an and the political dimension of MTQ. The effort to express the Koran aesthetically has actually emerged since the time of the Prophet Muhammad. One of the most popular stories is about the Islamic story of Umar ibn Khattab after hearing the reading of several verses of the Qur'an by his younger sister named Fatimah with her husband named Sa'id bin Zayd. Therefore MTQ is an opportunity to develop the art of reading the Qur'an, and an event to foster awareness to read and study the Qur'an.

Published: March 2019

In this study, the investigation of Local natural Iraqi rocks kaolin with the addition of different proportions of bauxite and its effect on the physical and mechanical properties of the produced refractories was conducted. Kaolin/bauxite mixture was milled and classified into various size fractions, the kaolin (less than 105 μm) and the bauxite (less than 70μm). The specimens were mixed from kaolin and bauxite in ranges B1 (95+5)%, B2 (90+10)%, B3(85+15)%, and B4 (80+20)%  respectively. The green specimens were shaped by the semi-dry method using a hydraulic press and a molding pressure of 7 MPa with the addition of (9-12) %wt. of PVA ratio. After molding and drying, the specimens were fired at (1100, 1200 and 1300) °C. Physical properties (density, porosity, water absorption) and mechanical properties (indirect tensile strength and hardness) were measured for all the prepared samples. The results showed that the porosity was increased and the density was decreased, such increase and decrease affected on to the mechanical properties for refractory. The highest values of indirect tensile strength and hardness were obtained at 20% Bauxite at 1300 °C (0.85386 MPa, 1411Kg / mm²) respectively.

Published: March 2019

Recently the use of nanofluids represents very important materials. They are used in different branches like medicine, engineering, power, heat transfer, etc. The stability of nanofluids is an important factor to improve the performance of nanofluids with good results. In this research two types of nanoparticles, TiO2 (titanium oxide) and γ-Al2O3 (gamma aluminum oxide) were used with base fluid water. Two-step method were used to prepare the nanofluids. One concentration 0.003 vol. %, the nanoparticles were examined. Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM) and X-ray diffraction (XRD) were used to accomplish these tests. The stability of the two types of nanofluids is measured by zeta potential and UV-vis spectrophotometer. The results showed that γ-Al2O3/water has more stable than TiO2/ water for the same period of time.

Authors: Ezzat Akram W. , Ghashim Sajida Lafta
Published: March 2019

An experimental study is conducted to investigate the effect of heat flux distribution on the boiling safety factor of its cooling channel. The water is allowed to flow in a horizontal circular pipe whose outlet surface is subjected to different heat flux profiles. Four types of heat flux distribution profiles are used during experiments: (constant distribution profile, type a, triangle distribution profile with its maximum in channel center, type b, triangle distribution profile with its maximum in the channel inlet, type c, and triangle distribution profile with its maximum in the channel outlet, type d). The study is conducted using heat sources of (1000 and 2665W), water flow rates of (5, 7 and 9 lit/min). The water temperature at cooling channel inlet is kept constant at (25°C). Copper test section of (0.6 m) length (0.025m) inner diameter is used during the experiments. The electrical heater used for water heating is wrapped around the copper pipe covering (50 cm) of its length. Calibrated thermocouples are distributed along pipe surface at distances (0.1, 0.2, 0.3, 0.4 and 0.5 m) from pipe inlet to measure pipe surface temperature. The results shows that the heat source with heat flux profile of type (c) is the most reliable one from thermo-hydraulic safety point of view for both types of heat sources, as it ensures a maximum boiling safety factor (K) of (1.6, 1.7, 2) at water flow rates of (5, 7 and 9 lit/min) respectively based on maximum heat capacity of (2665 w), while the heat source with heat flux profile of type (d) which posses minimum boiling safety factors of (1, 1.2, 1.3) at water flow rates of (5, 7 and 9 lit/min) respectively based on same heat capacity value is the worst one from same point of view.

Published: March 2019

Introduction. In increased requirements to occupational and personal qualities of workers engaged into or applying for dangerous professions, effi ciency of occupational selection considerably depends on choice of methodic approaches adequate to the study objectives. Objective. To study psychophysiologic approaches to evaluation of social psychologic reliability and occupational fi tness of individuals with dangerous professions, for revealing prognostic facilities of new methods and for improving occupational selection for military and police offi cers. Materials and methods. Psychophysiologic studies used eye-tracker SMI-RED–250 and polygraph “Diana” and covered 201 candidates for service in various divisions of RF Investigating Committ ee. Major part of the examinees consisted of individuals aged under 30 years (134 males and 67 females). All the candidates had normal vision or corrected to normal one. Evoked brain potentials study covered 114 candidates for military service (2 females and 112 males) aged 17 to 52 years. According to polygraph study, 51.8% of the examinees demonstrated a risk factor of “drug use”. Results. Th e authors presented results of psychophysiologic studies of occupational fi tness in candidates for military and police service. Nowadays, polygraph study remains a reliable method to reveal reactions proving presence of concealed information. Using evoked brain potentials for disclosing individuals who conceal drug usage is an important procedure in security maintenance. Within a standard polygraph procedure, videooculography (eye-tracker) seems the most interesting. Th e studies covered possible use of evoked EEG potentials and eye-tracker along with polygraph study for personnel checkups. Conclusions. Occupational selection in individuals with dangerous professions obtained experimental data indicating high effi ciency of combined use of eye-tracking and polygraph, for diagnosis of social psychologic reliability one can use soft ware of evoked brain potentials with demonstration of drugs-associated slides.
Strengthening of occupational health promotion by the German Prevention Health Care Act
Authors: Hart Diana
Published: March 2019

All countries are faced with the problem of the prevention and control of non-communicable diseases (NCD): implement prevention strategies eff ectively, keep up the momentum with long term benefi ts at the individual and the population level, at the same time tackling hea lth inequalities. Th e aff ordability of therapy and care including innovative therapies is going to be one of the key public health priorities in the years to come. Germany has taken in the prevention and control of NCDs. Germany’s health system has a long history of guaranteeing access to high-quality treatment through universal health care coverage. Th r ough their membership people are entitled to prevention and care services maintaining and restoring their health as well as long term follow-up. Like in many other countries general life expectancy has been increasing steadily in Germany. Currently, the average life expectancy is 83 and 79 years in women and men, respectively. Th e other side of the coin is that population aging is strongly associated with a growing burden of disease from NCDs. Already over 70 percent of all deaths in Germany are caused by four disease entities: cardiovascular disease, cancer, chronic respiratory disease and diabetes. Th ese diseases all share four common risk factors: smoking, alcohol abuse, lack of physical activity and overweight. At the same time, more and more people become long term survivors of disease due to improved therapy and care. Th e German Government and public health decision makers are aware of the need for action and have responded by initiating and implementing a wide spectrum of activities. One instrument by strengthening primary prevention is the Prevention Health Care Act. Its overarching aim is to prevent NCDs before they can manifest themselves by strengthening primary prevention and health promotion in diff erent sett ings. One of the main emphasis of the Prevention Health Care Act is the occupational health promotion at the workplace.

Authors: Hidayat Putro Heru Purboyo , Furqon Alhilal , Brilliyanti Astri
Published: March 2019

Pangandaran is one of the tourist destinations in Indonesia which has developed and has fairly strategic potential to encourage the regional and state economy. The rapid development of tourism in Pangandaran turned out to cause various problems. This is due to the lack of synergy among the roles of stakeholders involved in Pangandaran tourism management. In 2010, the Destination Management Organization (DMO) concept was implemented as an effort to improve the tourism destination governance in Pangandaran. This concept emphasizes the form of collaboration among stakeholders from community groups, the private sectors, and the government. The collaboration is led by the destination management organization (DMO) which serves as mediator, facilitator, and coordinator among the three stakeholder groups. This research is conducted in Pangandaran Village using mixed method which combines quantitative and qualitative research methods aimed to analyze the stakeholders who are involved in tourism destination governance in Pangandaran based on the DMO concept. From the results of the study, it is found that there are ten stakeholders who have high involvement on the tourism destination governance in Pangandaran. All of them have high level of interest and power, but there is one stakeholder who has high interest but low power in DMO-based tourism destination governance collaboration
Poder y cultura popular en Cartagena, 1900-1930: ¿transgresión o negociación?

El presente material tiene los limitantes del ensayo (en su acepción de experimento), un acercamiento iniciático, azaroso, no reposado. Más que certezas o hipótesis bien fundadas constituye sólo unas notas pergeñadas, leves intuiciones surgidas en el proceso de elaboración de nuestro trabajo de grado para optar el título de magister, que espero, se enriquezca con los aportes de los lectores.En él, exploraremos las formas de manifestación del poder, su puesta en escena en Cartagena de Indias, un espacio vinculado geoestratégica y culturalmente al gran Caribe insular; las negociaciones que este poder experimenta dadas las características económicas de la ciudad; y la relación entre el poder, la élite y los sectores populares, marginados, subalternos, o como prefiera llamárseles.

Eduardo Posada, LA NACIÓN SOÑADA. VIOLENCIA, LIBERALISMO Y DEMOCRACIA EN COLOMBIA.
Authors: Pitalúa Maico , Salas Luisinho
Published: March 2019

En las dos últimas décadas del siglo pasado un número considerable de historiadores se dio a la tarea de desmontar los “mitos” nacionales construidos por la historia tradicional colombiana. En los años 80`s fue el movimiento de la Nueva Historia la abanderada de este proceso. Las obras de Jaime Jaramillo Uribe, Germán Colmenares, Antonio Restrepo, Jorge Orlando Melo, José Antonio Ocampo, Jesús Antonio Bejarano y otros alimentaron la tradición revisionista puesta en boga años posteriores. Los postulados entre otros de Juan Manuel Restrepo e Indalecio Liévano Aguirre serían objeto de este nuevo impulso que tras la aplicación de nuevas técnicas y metodologías de investigación al trabajo historiográfico posibilitarían la construcción de un discurso alterno y renovador al dominante. Esta nueva tendencia implicó sin duda una mayor difusión de la obra histórica en Colombia.

ANTIFISCALISMO Y CULTURA POLÍTICA EN EL ESTADO SOBERANO DE BOLÍVAR (COLOMBIA), 1863- 1867
Authors: Luna Carlos Fanuel
Published: March 2019

Este ensayo pretende estudiar de qué maneras los comerciantes del Estado Soberano de Bolívar consolidaron su poder político y social a través de lo que aquí se denomina antifiscalismo político. Un conjunto de actitudes con las que recurrentemente confrontaban los mecanismos de regulación del Estado sobre sus actividades. Este antifiscalismo político fue la base de todas sus reclamaciones y presiones sobre la sociedad presentadas a través de artificios y discursos difundidos en la prensa e incorporados con un alto grado de centralidad en la opinión pública. Los intereses mercantiles aparecen durante el periodo de estudio como aspiraciones al tiempo particulares y colectivas configurando una cultura política caracterizada por la evasión constante de cualquier control público. A pesar de esto, en una población en su mayoría iletrada, el control y la manipulación de la opinión pública dependió de circuitos de comunicación oral que admitían sectores que la capacidad de leer la prensa excluía necesariamente. Este tpo de manifestaciones orales de juicios críticos y acríticos hacia quienes dirigían los negocios y el Estado constituyeron formas únicas de participación política no formal que, con toda y la centralidad de los intereses comerciales, eran determinantes en la conquista de la legitimidad.

En la introducción de una espléndida obra escrita a cuatro manos y cuya primera edición en inglés apareció en 1969, Eric J. Hobsbawm anotó:La principal razón para escribir otro libro acerca del Capitán Swing no es que podamos agregar nada importante a lo que ya se sabe a cerca de los acontecimientos de 1830 […] sino que ahora somos capaces de formular nuevas preguntas acerca de ellos: acerca de sus causas y motivos, de su modo de comportamiento social y político, de la composición social de los que tomaron parte en ellos, de su significación y sus consecuencias.Probablemente estemos de acuerdo en que han pasado ya muchos años entre 1969 y 2014, y en que de entonces a la fecha ha corrido suficiente tinta y se han elaborado muchos estudios sobre los trabajadores, sus organizaciones y sus expresiones culturales.

Elías José Palti, el tiempo de la política : el siglo XIX reconsiderado, Buenos Aires, Siglo XXI, 2007, 327 p.
Authors: Muñoz C. Andrés David
Published: March 2019

Señalar de pasada los plausibles aportes de un intento de historia intelectual de la cultura política, como la emprendida por el historiador argentino Elías José Palti, constituiría un inmenso logro para el autor de la presente reseña, quien valga decirlo, poco se encuentra familiarizado con los desarrollos teóricos y conceptuales de académicos como J. G. A. Pocock, Quentin Skinner o Reinhart Koselleck, y tan sólo ha tenido tímidos acercamientos a la obra insignia del historiador francés FrançoisXavier Guerra, Modernidad e Independencias. Ahora bien, si algo queda meridianamente claro tras la lectura (atenta, como no podría ser de otro modo) de El tiempo de la política, es que Palti, además de su declarada pretensión -muy desmedida- de escapar a una más que obvia adscripción al “revisionismo histórico”, propende por la elaboración de “un trabajo de historia intelectual” capaz de disolver, de hacer añicos todo rezago de historicismo y por ende de teleologísmo, en las interpretaciones que usualmente se han formulado en torno a la historia política de una Hispanoamérica, que en el siglo XIX atribuyó una importancia inmensa al lenguaje, dado que a partir de él se buscaba fundar un ideario del incipiente Estado nacional. Partiendo del estudio acucioso de los “lenguajes políticos” de las élites letradas del período en cuestión, Palti muestra los usos instrumentales conferidos a los discursos en boga tanto en la época del constitucionalismo gaditano, como en la segunda mitad del siglo XIX y evidencia la invención de dicotomías artificiales y falsas en la historiografía resultante, las cuales atribuye en su mayor parte a los practicantes de la hoy vetusta y desacreditada –en su opinión- “historia de ideas”.

Authors: Ramos Blanco Erick
Published: March 2019

No existe duda frente al hecho de que, aun cuando la Historia ha narrado innumerables ejemplos de los alcances que el ejercicio de dominación ha desencadenado, en la actualidad persisten diversas formas en las que tal actividad se sigue manifestando. Incluso, no es un secreto que, aparte de todos los conflictos que hoy mueven al mundo, persiste un grave residuo del, al parecer, inacabable problema de las razas. Esclavitud, exclusión, asimetrías raciales, invisibilización, racismo, supresión, rechazo, alteridad, son algunos de las expresiones con las que podríamos resumir una parte importante del proceso de vinculación social de los descendientes de africanos luego del fin de los sistemas coloniales. Sin embargo, es necesario afirmar que -a pesar de esto- desde las últimas décadas se ha desarrollado otra parte esencial de este proceso: el complejo enclave de movimientos políticos, culturales y académicos en el camino por construir una sociedad más justa e inclusiva para todos los grupos humanos. Y es precisamente a partir de la intención combativa y beligerante de los movimientos afro-latinoamericanos que es publicado el libro del cual es motivo esta reseña. Editado por Silvia Valero y Alejandro Campos García, Identidades Políticas en Tiempos de Afrodescendencia realiza un recorrido por las diferentes trayectorias que ha tomado el movimiento de los autodenominados afrodescendientes desde finales del siglo XX. Acogiendo países como Brasil hasta territorios insulares como el de Cuba, las diversas formas de acción de la diáspora africana fluctúan entre planes de naturaleza cultural e iniciativas de movilización política que funcionan a través de una serie de redes de organización –gubernamentales y no gubernamentales-, con el principal objetivo de disminuir los índices de desigualdad que afectan a los afrodescendientes.
Motion Control of Non-Holonomic Wheeled Mobile Robot Based on Particle Swarm Optimization Method (PSO)
Authors: Tawfik Mauwafak A.
Published: March 2019

Using (PID) controller to control the trajectory motion of non-holonomic wheeled mobile robot may not be efficient especially for non-linear systems. Hence this work introduces a combination of back stepping method with the (PID) controller to obtain an efficient controller for (WMR) to deal with the non-linear systems. Different common trajectories such as infinity, circle and straight line were applied to be tracked by (WMR) to examine the control system. The results of the simulation tests of the designated trajectories with the desired trajectories were achieved through the implementation of the mean square error for x, y and the orientation. Practical swam optimization method was used to find the control gain to investigate an optimized minimum error percentage. The results of simulation show a good tracking performance with the desired trajectories.

Authors: Al-Zuhairi Alaa H. , Ahmed Ammar Rafid
Published: March 2019

The aim of this research is to assess the validity of Detailed Micro-Modeling (DMM) as a numerical model for masonry analysis. To achieve this aim, a set of load-displacement curves obtained based on both numerical simulation and experimental results of clay masonry prisms loaded by a vertical load. The finite element method was implemented in DMM for analysis of the experimental clay masonry prism. The finite element software ABAQUS with implicit solver was used to model and analyze the clay masonry prism subjected to a vertical load. The load-displacement relationship of numerical model was found in good agreement with those drawn from experimental results. Evidence shows that load-displacement curvefound from the finite element model has almost the same shape and pattern of the experimental one. The curves in both situations become more and more resembling as the load increasing till they reach failure.
Lubricating Properties of Water-Based Drilling Fluid Improvement Using Lignite NPs as well as Their Effect on Rheological and Filtration Properties
Authors: Salam Massara , Al-Zubaidi Nada S. , Al-Wasiti Asawer A.
Published: March 2019

In the process of drilling directional, extended-reach, and horizontal wells, the frictional forces between the drill string and the wellbore or casing can cause severe problems including excessive torque which is one of the most important problems during drilling oil and gas well. Drilling fluid plays an important role by reducing these frictional forces. In this research, an enhancement of lubricating properties of drilling fluids was fundamentally examined by adding Lignite NPs into the water-based drilling fluid. Lubricity, Rheology and filtration properties of water-based drilling fluid were measured at room temperature using OFITE EP and Lubricity Tester, OFITE Model 900 Viscometer, and OFITE Low-Pressure Filter Press, respectively. Lignite NPs were added at different concentrations (0.05 %, 0.1 %, 0.2 %, 0.5 %, and 1 %) by weight into water-based drilling fluid. Lignite NPs showed good reduction in COF of water-based drilling fluid. The enhancement was increased with increasing Lignite NPs concentrations; 23.68%, 35.52%, and 45.3 % reduction in COF were obtained by adding 0.2%, 0.5%, and 1% by weight Lignite NPs concentration, respectively.
Movable Thermal Screen For Saving Energy Inside The Greenhouse
Authors: Shakir Saif Mahmood , Farhan Ammar A.
Published: March 2019

In this work, a movable thermal screens was designed and examined for the purpose of decreasing greenhouse heating loss in Baghdad during winter nights. Three types of automatic movable thermal screens were tested to decrease the heat loss inside a greenhouse. The transparent cover area was 29.2   with 4 mm glass cover thickness. The mathematical model was formulated in four parts which are the inside air, transparent cover, soil surface, and subsoil layer. The results of the thermal curtains showed that the average temperature of the inside air during the night for the polyethylene, polypropylene, and bubble films was 8.1 ̊C, 10.3 ̊C, and 12.5 ̊C respectively and greenhouse without screens was 5.9 ̊C. These results showed that the bubble film was more effective in a saving energy than polypropylene and polyethylene films. Good agreement was obtained between the mathematical model and the measured values (with relative root mean square errors below 5%). It was shown that the suggested different types of movable thermal curtains were powerful in decreasing heating losses, which is reached about 21.7 % compared with a greenhouse without curtains.

Authors: Taj Ali I. , Al-Zuhairi Alaa H.
Published: March 2019

In this study, plain concrete simply supported beams subjected to two points loading were analyzed for the flexure. The numerical model of the beam was constructed in the meso-scale representation of concrete as a two phasic material (aggregate, and mortar). The fracture process of the concrete beams under loading was investigated in the laboratory as well as by the numerical models. The Extended Finite Element Method (XFEM) was employed for the treatment of the discontinuities that appeared during the fracture process in concrete. Finite element method with the feature standard/explicitlywas utilized for the numerical analysis. Aggregate particles were assumedof elliptic shape. Other properties such as grading and sizes of the aggregate particles were taken from standard laboratory tests that conducted on aggregate samples.Two different concrete beamswere experimentally and numerically investigated. The difference between beams was concentrated in the maximum size of aggregate particles. The comparison between experimental and numerical results showed that themeso-scale model gives a good interface for the representing the concrete models in numerical approach. It was concluded that the XFEM is a powerful technique to use for the analysis of the fracture process and crack propagation in concrete.

Acremonium cellulase and optimash BG hydrolyzed the pretreated sample into fermentable sugars. In condition of 10% substrate concentration, ball milling for 60 min and 4 FPU/g enzyme loading and optimum sugar yield were observed. By comparison, jatropha stem is more favorable feedstock compared to jatropha husk in terms of both inherent sugar composition and sugar yield in enzymatic saccharification (hydrolysis). Yeast Saccharomyces cerevisiae, capable of converting hexose sugars into ethanol,was utilized in fermentation step. It was possible to extract 0.14 L and 0.20 L of ethanol per kg of dry substrate-based jatropha husk and jatropha stem, respectively.

Critique of Experimental Research on Selfless Assertions
Authors: Gaszczyk Grzegorz
Published: March 2019

In this paper, I show that Turri’s (2015a) experimental study concerning selfless assertions is defective and should therefore be rejected. One performs a selfless assertion when one states something that one does not believe, and hence does not know, despite possessing well supported evidence to the contrary. Following his experimental study, Turri argues that agents in fact both believe and know the content of their selfless assertions. In response to this claim, I demonstrate that the conclusions he draws are premature in this regard. More specifically, I criticize his methodology, showing that his study is not only incomplete but also yields contradictory results. In closing, I propose how such a study should be conducted in order to receive comprehensive results.

Published: March 2019

O objetivo deste estudo é analisar como as Práticas Corporais de Aventura (PCA) foram desenvolvidas na escola nos últimos 10 anos; cujos descritores - esportes, aventura, práticas corporais, conteúdo, educação física, natureza, meio ambiente, permitiram encontrar 122 estudos em 4 bases de dados: Scielo; Google Acadêmico, Redalyc e Lilacs. Pelos critérios de inclusão e exclusão foram eleitos 5 estudos. Nota-se práticas didático-pedagógicas, ao contemplar as dimensões dos conteúdos, estreitando a relação entre o ser humano e a natureza. Contudo, concluímos que o potencial das PCA para o desenvolvimento cognomotor não foi contemplado nos estudos, nas suas dimensões das funções cognitivas e motoras interconectadas, fazendo-nos inferir que o paradigma atual ainda não é o embodied cognition, onde corpo e mente estão indissociavelmente juntos. Cabe aos professores, secretarias de educação e Instituições de Ensino Superior, fomentarem formação específica tanto na graduação quanto na pós-graduação.

A língua Portuguesa falada no Brasil está em evolução com as influências sociais. O objetivo deste artigo é verificar a incidência do uso de vícios de linguagem, especificamente o uso do termo “tipo”,  entre jovens estudantes universitários de uma universidade brasileira. Realizou-se uma pesquisa online para saber os vícios de linguagem mais comuns entre os estudantes e a frequência com que ocorrem no discurso. Os dados mostraram que a o termo “tipo” está entre os mais falados entre os informantes, perdendo apenas para os termos “vei” e “mano” e está associada à ideia de incerteza, despreparo, vício ou imitação e falta de ampliação de vocabulário. Pode-se concluir que urge uma intervenção acerca das práticas comunicativas e linguageiras nas escolas para que haja mudança no uso dos vícios de linguagem, sobretudo entre o público estudado.

Authors: Mendes Geane Martins , Bezerra Leonardo Mendes
Published: March 2019

No Brasil a formação inicial de professores emergiu após a independência do país, período em que se cogitou a organização da instrução popular. A partir disso, iniciou-se à criação das escolas Normais, com o escopo de formar e capacitar os professores. No Estado do Maranhão, a Universidade Estadual do Maranhão (UEMA) potencializou a formação docente, com a oferta dos cursos de licenciatura, mostrando assim sua vocação na graduação de professores. Diante disso, o objetivo central do artigo registrou as contribuições que o Centro de Estudos Superiores de Balsas (CESBA) campus da UEMA proporcionou com a formação, capacitação e qualificação inicial de professores, para a sociedade Sul-maranhense. Para a realização do estudo, foi preciso pautar-se na pesquisa bibliográfica; documental, nos Projetos Pedagógicos de Cursos e na pesquisa de campo, com a aplicação de questionários aos egressos das licenciaturas. A aplicação dos questionários ao público investigado buscou descobrir as opiniões em relação aos aspectos da formação profissional no referido Centro. Como resultado, estabeleceram-se três categorias de análise: 1. Filosofia educativa do CESBA para a formação de professores, 2. Os objetivos, as competências e as habilidades na formação docente, 3. Percepções a respeito da formação inicial dos professores.  Por fim, esses estudos nos proporcionaram entender parte da história da formação da formação inicial de professores, perceber fatores que foram preservados, o que mudou, e principalmente, o que precisa de melhorias.

Published: March 2019

Recebido:   20/03/2018 Aprovado:   15/05/2018Publicado:  10/06/2018O objeto deste artigo envolve, sobretudo, os recentes acontecimentos históricos no país a partir de um golpe de Estado, apoiado e orquestrado por grupos empresariais jornalísticos, significativa parcela do Congresso Nacional e o Poder Judiciário. Há indícios ou evidências de manipulação, seletividade e distorção das notícias por parte dos grupos empresariais jornalísticos diante dos atuais acontecimentos políticos, econômicos e sociais no Brasil, configurando-se em veículos estrategicamente especializados em disputar a memória social e desqualificar/criminalizar, sistematicamente, os movimentos populares. Assim, alicerçados em pesquisa bibliográfica e documental, intencionamos, por meio da perspectiva da História do Tempo empreender uma análise teórica que aponte os riscos do falseamento da realidade histórica e os seus efeitos para o processo formativo das gerações subsequentes. Palavras-Chave: Memória social, História do tempo presente, grupos empresariais jornalísticos.
Cartografia e geopolítica das relações sul-sul: sobre a cooperação técnica Brasil-África.
Authors: Rocha André Santos da
Published: March 2019

Nos últimos 20 anos, o Brasil buscou alternativas para potencializar sua projeção no cenário internacional, um destes caminhos foi a reorientação de sua política externa que valorizava as relações Sul-Sul. Essa relação é caracterizada pela aproximação comercial, alinhamento político e acordos de cooperação técnica com países periféricos e emergentes. Entendemos a política externa e a Cooperação Sul-Sul como uma forma do exercício geopolítico de projeção hegemônica e que os fomentos aos acordos de cooperação fazem parte de uma projeção que territorializa estratégias mundiais de um Estado. No período de 2003-2010, o continente africano foi alvo desta estratégia de política externa Sul-Sul brasileira recebendo grande parte dos investimentos de cooperação técnica. Assim, apresentamos uma cartografia das principais áreas de cooperação técnica e demonstramos que, num conjunto, ela expressa uma tendência geopolítica que amplia relações diplomáticas com outros países do continente africano, para além daqueles parceiros já consolidados falantes de língua portuguesa.
Feira livre e reprodução camponesa no município de Irará/BA
Authors: Alcântara Andréia Silva de , Pertile Noeli
Published: March 2019

No processo histórico de formação do município de Irará os ex-escravos reorganizaram suas táticas de resistência no campo através das diferentes formas de acesso a terra (posseiro, parceiro, arrendatário, ocupante e pequeno proprietário) e disso resultou a existência dos atuais camponeses. Este é o contexto em que foi forjado o campesinato no município de Irará que permite a continuidade da luta e a preservação do modo de vida camponês, expresso por meio da agricultura tradicional nas diversas manifestações do saber-fazer desse grupo social. Assim, grande parte da produção agropecuária municipal é comercializada na feira livre do município de Irará. A feira livre configura-se como instrumento oxigenador da economia camponesa. É onde o camponês exerce a troca de mercadorias por ele produzidas (do que excede em seu estabelecimento) por dinheiro e outros produtos fundamentais a sua subsistência. A feira livre também é o espaço das relações de sociabilidade, das manifestações culturais e do lazer. A feira livre do município de Irará apresenta uma diversidade de produtos, que são oriundos, em sua maior parte, das comunidades rurais do município de Irará. A diversidade desses produtos expressa a importância da agricultura camponesa no abastecimento do mercado local. Por conseguinte, a feira livre do município de Irará é o espaço onde se movimenta a economia local, é onde o trabalho do camponês se materializa em moeda de compra e troca. É o espaço que garante a reprodução camponesa e ao mesmo tempo, tece as relações entre o campo e a cidade.
