Authors: Moreira Gomes Ana Virgínia , Leitão Saraiva Cláudio Henrique
Published: December 2017

O artigo tem como objetivo refletir acerca da aplicação do interdito proibitório pelas cortes trabalhistas ao examinar quais critérios a Justiça do Trabalho utiliza para a concessão de interdito proibitório – tutela jurisdicional que visa à proteção da posse – no contexto de uma greve. Para tanto, primeiro, o artigo desenvolve uma análise doutrinária e jurisprudencial do interdito proibitório no Direito Processual Civil e no Direito do Trabalho; segundo, o estudo analisa um conjunto de julgados selecionados, considerando os critérios usados na argumentação das decisões. Para a segunda parte do estudo, o artigo realiza uma pesquisa empírica, que consiste na coleta de dados em acórdãos do Tribunal Regional do Trabalho da 2ª Região, que julgaram aspectos sobre o interdito proibitório e a greve até o dia 1º de novembro de 2016. A metodologia da pesquisa é empírica, uma vez que envolve análise dos julgados do TRT/SP, desenvolvendo o exame quantitativo e textual dos dados que traçam um panorama do interdito proibitório em âmbito da greve.
PESQUISA EMPÍRICA NO SISTEMA PRISIONAL: construindo experiências
Authors: Mello Priscila Vargas , Da Silva Joana Coelho , Rudnicki Dani , Costa Ana Paula Motta
Published: December 2017

Este artigo analisa as dificuldades impostas aos pesquisadores das instituições prisionais. Para tanto, partimos da experiência no desenvolvimento de pesquisas empíricas na Penitenciária Feminina Madre Pelletier e no Presídio Central de Porto Alegre, entre os anos de 2013 e 2015. Refletimos sobre a entrada no campo e as barreiras encontradas para a realização das pesquisas, que vão além da autorização inicial para o seu começo. Além da dificuldade burocrática para conseguir a aprovação dos órgãos reguladores e dos comitês de ética, os pesquisadores enfrentam obstáculos impostos pelas relações que se estabelecem com os indivíduos observados. Além disso, os pesquisadores são percebidos de diferentes formas: como um inimigo dos operadores jurídicos e profissionais que ocupam o espaço da prisão e da justiça criminal; como alguém cuja atuação implica em mais trabalho e como aquele que registra histórias e experiências de vida, informações. A entrada no campo, pois, significa a necessidade de conquistar espaço, estabelecer relações com as pessoas e com o poder. Logo, a pesquisa no âmbito prisional se mostra complexa e difícil, mas necessária para conhecer um local tão diverso e paradoxal.
DECIFRANDO O FÓRUM JOÃO MENDES: o que os números nos dizem?
Authors: Yeung Luciana L.
Published: December 2017

O objetivo deste trabalho foi avaliar o perfil das ações iniciais no tribunal de maior movimentação no Estado de São Paulo, o Fórum João Mendes. Com o uso de recursos computacionais de big data, extraímos e avaliamos a população de ações iniciadas em cinco varas do João Mendes, durante todo o ano de 2014. O total de casos analisados foram 11.959. Em consonância com o observado em tribunais superiores, nossos resultados indicam uma forte concentração de casos em um pequeno número de empresas, fortemente representadas por aquelas do setor bancário. Por outro lado, a maior parte das ações envolviam partes únicas, de procedimento ordinário, e com valores de causa relativamente baixos, apesar da grande dispersão. Trabalhos futuros poderiam se propor a construir um índice de complexidade dessas ações iniciais, e averiguar se existe alguma significativa diferença entre o grau de complexidade médio dos casos trazidos ao Fórum João Mendes em comparação àqueles de outros tribunais.

Por uma teoria psicogeográfica da comunicação
Authors: Ferrara Lucrécia D'Allessio , Balbi Thiago Machado
Published: December 2017

Considerando certa escassez de teorias comunicacionais atentas ao comunicar espontâneo do cotidiano, o trabalho destina-se à reflexão sobre o conceito de psicogeografia com tal propósito. O termo psicogeografia foi usado pela Internacional Situacionista para designar os estudos do grupo sobre as influências que atingem a relação entre o indivíduo e o ambiente geográfico. Propõe-se uma articulação entre o viés prático/empírico dos situacionistas e teorias de geógrafos como Augustin Berque, Milton Santos e Henry Lefebvre, para os quais a relação da humanidade com o seu meio é, sobretudo, uma relação comunicativa.
Uma análise interpretativa sobre as práticas comunicacionais nas construções identitárias dos migrantes haitianos em Curitiba-PR
Authors: Ávila Otávio Cezarini , Del Vecchio de Lima Myrian
Published: December 2017

Os haitianos se tornaram conhecidos da população brasileira, em especial, nas grandes capitais do país. Nas ruas, nos postos de trabalho, em eventos populares, os migrantes haitianos aparecem em nosso imaginário sob diferentes formas representacionais, normalmente, mediadas pelos discursos dos meios de comunicação de massa. O objetivo do artigo é discutir como determinados processos comunicativos, que ocorrem fora do “circuito oficial” da comunicação (TV, jornais, rádio e sites de mídias tradicionais), desestabilizam os discursos hegemônicos em prol de uma “cidadania transnacional”, de direitos e de dignidade ao migrante haitiano que vem ao Brasil e, mais especialmente, a Curitiba, no Paraná. O artigo, que é parte de uma pesquisa de mestrado, invoca a relação que a temática da migração mantém com o processo de globalização contemporânea, com as redes sociais que podem atuar como formas discursivas contra-hegemônicas e com perspectivas metodológicas que extrapolam os dados quantitativos para trazer perspectivas valorativas das identidades dos migrantes. Parte-se da premissa de que as práticas comunicativas dos migrantes haitianos constituem formas de resistência frente a processos de vida acelerados pela globalização, especialmente, aqueles relativos às identidades. Apresentam-se, como resultado, algumas formas como os haitianos têm utilizado diversas interações midiáticas para se colocar no novo território.
Legal System for Endorsing Press Independency in Indonesia
Authors: Wiratraman Herlambang Perdana
Published: December 2017

Political transition of post Soeharto's authoritarian regime has been deeply influenced by a decentralised model of governance, which affected to more serious attacks to the journalism works. The extra-judicial killing, physical violence, criminalising against journalism, and other attacks through formal judicial process or other forms, included impunity system, have shown uneasy situation for journalist at field or members of the press to perform journalistic works. Violence against journalists at field in decentralised Indonesia has been more influenced by the role of political-economy contestation at the local level, rather than the influence of situation and policies at national level. The law enforcement to protect journalist at works seems easily deniable and disregarded due to law system itself that does not give significance effect. The court has been used to collapsing media, silencing opposition, retaliating, and terrorising journalism works.

My research shows that the most targeted medias for ULAP (unjustifiable lawsuits against press) or criminalisation have been connected to its reliability, professionalism journalistic or high quality of news. On the other side, impunity has prevailed and become a dominant situation that is not merely caused by ‘external media’ factors, but also showed an ‘internal media’ factors. Avoiding the judiciary becomes phenomena that does not always relate to distrust over the judicial system, but more on a ‘forced situation’. In my presentation, I will show how this situation articulates a new configuration of political imperium which combines of free press and dominant ownership over media, plus illiberal democracy which legally allows and lets predatory system to be supreme class in the governance and other state institutions.
Human Rights in Southeast Asia
Authors: Menski Werner F
Published: December 2017

Many challenges exist regarding the discourse over human rights in South East Asia due to the complex relationship between the region’s myriad cultures, laws, religions and political desires. This socio-political environment produces a number of varying, and often contradictory, interpretations of human rights, as well as differing opinions on how they should be implemented. On one hand, some countries in Southeast Asia have internalized international human rights instruments by amending their constitutions in order to provide a semblance of protection for their citizen’s human rights. On the other hand, some countries still operate under authoritarian regimes and continue to violate certain internationally recognized rights for the sake of preserving political stability and economic development. Proponents of such regimes often claim that this is done to maintain both societal and religious harmony. Therefore, the effort to address human rights issues in Southeast Asia must expand beyond the international legal sphere and take into account the intricate relationships and power struggles between the region’s various economic interests, social and cultural norms, and religions. Furthermore, the successful implementation of human rights law in Southeast Asia will require a number of obligations and checks be imposed on the state governments in the region. The specific means by which to promote human rights in South East Asia, and how to reconcile diverging options on the definition and scope of said rights, was the theme of the 2nd Annual Conference of the Centre for Human Rights, Multiculturalism and Migration (CHRM2) and Indonesian Consortium for Human Rights Lecturers (SEPAHAM Indonesia), held in August, 2017, at the University of Jember. This article is a summary of the major points and topics covered during the two day conference.

As tecnologias de informação e comunicação (TIC) na área contábil assumem papel relevante e refletem o avanço na profissão do contador. A contabilidade aliada à TIC proporciona mais agilidade na realização dos registros contábeis e no gerenciamento das atividades empresariais. A TIC é, na atualidade, uma das ferramentas fundamentais para facilitação do processamento de dados contábeis. O Modelo de Aceitação Tecnológica (TAM) é amplamente utilizado para avaliar o nível de adoção de TIC. Os fundamentos do TAM expressam que os indivíduos tendem a adotar determinada tecnologia a partir da facilidade percebida de uso e do valor de sua utilidade percebida. Esta pesquisa de campo utilizou um questionário com 16 perguntas fechadas estruturada como escala do tipo Likert com 7 pontos, os dados foram tratados e avaliados por meio de Modelagem de Equações Estruturais, utilizando-se o software SmartPLS 3.2.1 com o objetivo de analisar a aceitação tecnológica no ambiente contábil. Os achados da pesquisa revelam que os indicadores que predizem o constructo da intenção comportamental são adequados para explicar 32,3% do modelo e o uso atual do sistema apresenta um poder de esclarecimento em torno de 23,9% por meio de constructos que preveem este comportamento.
Eficiência técnica e inovatividade: um estudo em hospitais privados brasileiros
Authors: Chieppe Saquetto Thiago , Janes Carneiro Teresa Cristina , Affonso Silva Araujo Claudia , Fossatti Figueiredo Kleber
Published: December 2017

Os hospitais têm procurado melhorar seu desempenho e a inovatividade tem sido destacada como um aliado nessa missão. O objetivo da pesquisa foi verificar se a percepção de inovatividade dos gestores de hospitais está relacionada com o desempenho de suas organizações. A inovatividade foi definida como uma medida da capacidade da empresa de inovar e foi operacionalizada mediante variáveis relacionadas à inovatividade organizacional e à inovatividade percebida da firma. O desempenho foi definido pela eficiência do hospital em utilizar os recursos disponíveis para prestar serviços. Os resultados de um survey, realizado com gestores de 20 hospitais privados pertencentes a maior operadora de planos de saúde do Brasil, mostraram que a inovatividade percebida possui relação inversa com a eficiência técnica: quanto maior a capacidade ou propensão da empresa a inovar, tanto percebida pela cultura interna da organização quanto por sua forma de atuar no mercado, menor a eficiência técnica do hospital.
Stability of Corn and Soybean Yield Ratios in Three Midwestern Environments
Authors: Egli D. B.
Published: December 2017

Core Ideas

Corn/soybean yield ratios estimate species × environment interactions.

County yields from Kentucky, Iowa, and Nebraska (1972–2015) were used.

Cropping systems had a greater effect on average ratios than productivity level.

Year‐to‐year variation in the ratio decreased as the productivity level increased.

Yield ratios increased significantly in only 37% of the counties (mostly in Iowa)

Developing cropping systems to maintain productivity in future environments will require a better understanding of crop species × environment interactions. The ratios of county corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] yields (corn/soybean) from three midwestern states (Kentucky [31 counties], Iowa [47 counties] and Nebraska [irrigated, 33 counties]) (1972 through 2015) were used to evaluate this interaction. Yield estimates (converted to a weight basis) were obtained from the National Agriculture Statistics Service. Average yield ratios were similar in Iowa (2.96) and Nebraska (3.00) in spite of higher yields in Nebraska. The highest average ratio (3.39) occurred in Kentucky counties where soybean double cropped after winter wheat (Triticum aestivium L.) predominated. Yield ratios were remarkably stable (low CVs) over time in high‐yield environments, but stability decreased as county productivity (estimated by average corn yield) decreased (CVs increased from ∼8 to 23%). The mean yield ratios in Kentucky and Nebraska decreased significantly as the proportion of continuous corn in a county increased. The largest yield ratios in non‐double crop counties in Kentucky were associated with a larger proportion of continuous soybean in the rotation. Yield ratios increased significantly (p < 0.10) from 1972 to 2015 in only 37% of the counties (mostly in Iowa). The largest interactions between corn and soybean involved cropping systems and not fundamental physiological characteristics of these species. The consistency of mean yield ratios in rain fed and irrigated environments suggests that these crops may respond similarly to changes in precipitation.
Historical perspective of soil balancing theory and identifying knowledge gaps: A review
Authors: Chaganti Vijayasatya N. , Culman Steve W.
Published: December 2017

The common philosophies that contextualize soil test results and fertilizer recommendations are sufficiency level of available nutrients, buildup and maintenance, and basic cation saturation ratio (BCSR). The BCSR approach postulates maintaining an ideal ratio of basic cation saturations on the soil exchange sites to maximize crop yields. The practice of adding amendments to alter the ratios of basic cation saturations in soils is called “soil balancing.” While the scientific community disregards this theory, some farmers, crop consultants, and commercial soil‐testing laboratories still use BCSR to guide their fertilizer recommendations.

Authors: Shkodra Jehona , Ismajli Hysen
Published: December 2017

The determinant of the credit risk of banks in a developing country have limited data to analyze and limited participation in literature. Determinants of credit risk are very important in order to define the non-performing loans (NPL) in Kosovo banking systems. Even though banking system in Kosovo is the newest in region, it is comparable with banking systems to all places in regions (Albania, Serbia, Montenegro, Macedonia, Bosnia and Herzegovina, etc.).The main purpose of this paper is to classify some factors that influence credit risk in commercial banks in Kosovo. The research includes seven commercial banks for the period 2006–2015. Data analysis and interpretation are processed with Statistical Program for Social Sciences SPSS v.19.0.The effect of variations in the determinants of credit risk exposure is based on using a multivariate panel regression model. Our empirical results suggest that a significant relationship exists between credit risk and the following variables: Profitability (ROE and ROA), Inefficiency (IE), Loans to deposit ratio (LDR), Credit growth (CG) and Deposit rate (DR), while variables of Solvency (SR) and Credit rate (CR) are not statistically significant in terms of credit risk.
Geospatial Suitability Mapping of Climate-based Disease Transmission using Fuzzy Logic for Central India
Authors: Mehra Parihar Seema , Sarkar Soma , Kumar Premendra
Published: December 2017

Geographic Information System (GIS) today supports health and disease mapping in diverse ways. Present study divulges geographic dimensions of malaria disease in Madhya Pradesh and Chhattisgarh states located in Central India. Chhattisgarh is second and Madhya Pradesh is the third most malarious states after Odisha in India. In the present study, an attempt is made to map climate-based malaria transmission suitability using fuzzy logic for Central India. Temperature and relative humidity were selected as the two indicators for malaria transmission suitability analysis. District wise meteorological data for 2008 was used for the present study. Monthly temperature and relative humidity interpolation maps were generated using ‘Natural Neighbor’ interpolation algorithm. For both the indicators trapezoidal membership function was selected. Arc GIS software and its FUZZY tool were used to generate ‘climate suitability map’ for malaria transmission depicting the spatial distribution of Transmission Window length (in months) across the region. The findings illustrate that most districts of Chattisgarh and very few districts of Madhya Pradesh have transmission window open for more than 10 months and are identified as ‘High Endemic Regions’. Compared to Chhattisgarh, Madhya Pradesh experiences more numbers of least suitable months i.e. February, March, April and May. The study aims to benefit judicious decision making for efficient intervention implementation.

Authors: Song Mengmeng , Xiao Shungen , Song Haixia , Huang Lixia
Published: December 2017

Dynamic behavior of reciprocating compressor system, with translational clearance between the crosshead and guide under time-varying cylinder load, is investigated. In order to analyze the dynamic response of the system with translational clearance, a novel nonlinear dynamic model is established based on the Lagrangian approach. The numerical solution of the dynamic equation is calculated by the Runge-Kutta method. The results show that the translational clearance has a great effect on the reciprocating compressor, and the more the translational clearance, the great the influence. Moreover, the phase space of the crosshead reveals that the reciprocating compressor system with translational clearance has chaotic characteristics.
Numerical study on axial vibration of water-lubricated small thrust bearing considering grooved pad
Authors: Boonlong Kittipong , Jeenkour Puttha
Published: December 2017

This paper presents the effect of pad with transverse grooves on the axial vibration for a small thrust bearing under water lubricated. Due to downsizing of electronic devices, the component part such as the thrust bearing in the micro fabrication becomes small size. Therefore, to study the characteristic of vibration for a small thrust bearing under water lubricated is significant for high precision machining. The hydrodynamic lubrication model was used to predict the water film thickness, the water pressure profile, and the bearing stiffness. A finite difference method (FDM) and a Newton-Raphson scheme are employed to achieve numerical results, i.e. the water pressure distributions, the water lubricating film thicknesses and the bearing stiffness under the variation of groove depths. The grooved shape of pads, that examined in this paper, was elliptical shape. The equation of motion under the impulse excitation considering in the axial vibration for a small thrust bearing was solved by using a Runge-Kutta method. The numerical results showed that the use of elliptical transverse grooves is effective to increases the fluid film stiffness and the maximum displacement in the axial vibration is able to be reduced.
Axisymmetric scattering of a fluid spheroid illuminated by an acoustical Bessel beam
Authors: Wang Mingsheng , Li Wei
Published: December 2017

Depending on the partial wave series expression, the scattering of a fluid spheroid illuminated by a zeroth-order Bessel beam is calculated in the spherical coordinate. For a fluid spheroid, the scattering is associated with the host medium, and the immersed spheroid medium. Although spherical and cylinder fluid objects has been discussed a lot before, a prolate and oblate fluid spheroid has not been investigated deeply. In the paper, two limited boundary conditions (Neumann and Dirichlet) are presented and discussed about far-field scattering form functions. By comparing these two limited conditions, the analysis could be applied into underwater detection and acoustic tweezers, or other fields. For other fluid materials, this method could also be utilized to calculate and analyze.

Authors: Zou Zhihong , Li Wei , Wang Mingsheng
Published: December 2017

It’s generally different to predict the acoustic target strength of a submarine with anechoic coatings by conventional finite element method (FEM). Parameter inversion is a common method to solve this problem. Some researchers have studied the parameter inversion about normal incidence of anechoic coatings. In this paper, the FEM of impedance tube is used to obtain acoustic reflection coefficient of anechoic coatings. Then the genetic algorithm is applied to acquire the physical parameters of viscoelastic material which is equivalent to anechoic coatings. The LMS Virtual Lab is used to construct finite element model of the anechoic coatings to validate the parameter inversion with normal incidence.

Review and comparison of performance indices for automatic model induction
Authors: Chadalawada Jayashree , Babovic Vladan
Published: December 2017

One of the more perplexing challenges for the hydrologic research community is the need for development of coupled systems involving integration of hydrologic, atmospheric and socio-economic relationships. Given the demand for integrated modelling and availability of enormous data with varying degrees of (un)certainty, there exists growing popularity of data-driven, unified theory catchment scale hydrological modelling frameworks. Recent research focuses on representation of distinct hydrological processes using mathematical model components that vary in a controlled manner, thereby deriving relationships between alternative conceptual model constructs and catchments’ behaviour. With increasing computational power, an evolutionary approach to auto-configuration of conceptual hydrological models is gaining importance. Its successful implementation depends on the choice of evolutionary algorithm, inventory of model components, numerical implementation, rules of operation and fitness functions. In this study, genetic programming is used as an example of evolutionary algorithm that employs modelling decisions inspired by the Superflex framework to automatically induce optimal model configurations for the given catchment dataset. The main objective of this paper is to identify the effects of entropy, hydrological and statistical measures as optimization objectives on the performance of the proposed approach based on two synthetic case studies of varying complexity.
A total cost minimization control for wastewater treatment process by using extremum seeking control
Authors: Yamanaka Osamu , Onishi Yuuta , Namba Ryo , Obara Takumi , Hiraoka Yukio
Published: December 2017

This paper presents a real-time optimal control scheme based on a total cost index (TCI) by using the so-called extremum seeking control (ESC). The ESC searches the minimum value of a given performance index where the TCI consisting of the operational cost and the effluent quality cost is used as the index. An improved ESC is proposed where a transformed TCI by monotonically increasing function is utilized to improve the convergence property of the ESC while keeping the argument of the optimal point invariant. The feasibility of the ESC is tested for two types of pseudo-anaerobic-oxic process control: one is the return sludge recycle ratio control, and the other is the aeration control for an alternate zone which can be anaerobic or aerobic depending on the influent condition. Simulation study illustrates that the proposed ESC is able to find a near optimal point successfully and the TCI can be reduced by about 2.7 to 3.8% compared with that of a typical operating condition.
Solid–liquid separation of an effluent produced by a fixed media biofilm reactor
Authors: Patry Bernard , Boutet Étienne , Baillargeon Serge , Lessard Paul
Published: December 2017

An experimental study dedicated to the characterization of the settleability of solids produced in immersed fixed media biofilm reactors has been carried out. The influence of operating temperature (0.1 to 16 °C) and surface organic loading rate (OLR) (0.4 to 10 g of soluble carbonaceous BOD5 per m2 of media per day) on settleable solids quantities, particle size distributions (PSD) as well as flocs morphology was evaluated. Results have shown that the OLR has no statistically significant influence on the settleability of the suspended solids. However, the operating temperature was identified as a factor that significantly influences the settling potential. The highest operating temperatures (14–16 °C) were related to the worst settling performances. On the other hand, the best settling performances were observed at intermediate operating temperatures (around 10 °C). The latter conditions were also associated with the largest fractions of large particles (>100 μm) in the effluent. Differences in PSD were found to be well correlated with settling performances. Part of the performance results variability which cannot be explained by differences in PSD can potentially be attributed to differences in flocs morphology (compactness).
δ13CDIC tracing of dissolved inorganic carbon sources at Three Gorges Reservoir, China
Authors: Wu Qixin , Han Guilin
Published: December 2017

In order to understand water chemistry after impoundment of the Three Gorges Reservoir (TGR), the authors assessed the hydrogeochemical parameters (water temperature, pH, conductivity, dissolved O2), major element composition, and the carbon stable isotopic value of dissolved inorganic carbon (δ13CDIC) in summer and winter at various depths in the water column at TGR in 2009. In reservoir water, the DO values are lower in winter than in summer, but the pH values and conductivity values are higher. Ca2+ and Na+ are the dominant cations and HCO3− and SO42− are the dominant anions. In surface waters, the δ13CDIC values are more negative in summer than they are in winter, whereas the dissolved inorganic carbon (DIC) concentrations are relatively lower. In the water column, the DIC and δ13CDIC values do not change significantly with water depth or seasons. The DIC content shows a dilution effect in summer and is not modified by phytoplanktonic activity or photosynthesis. Even after the dam obstructed flow, the chemical profile of water in TGR is similar to that of the natural rivers before impoundment. Therefore, in this study, the water at TGR still had riverine characteristics and was still a heterotrophic system.

O objetivo deste artigo é analisar a base de conhecimentos de professores experientes e participantes do Programa de Formação Online de Mentores da UFSCar-Brasil, bem como responder à seguinte questão: quais dos conhecimentos específicos, pedagógicos e sobre a função de mentor, que o auxiliarão a desempenhar a nova função, podem ser apreendidos nos professores experientes, participantes do Programa de Formação Online de Mentores? O Programa é responsável pela formação de mentores, sua proposta curricular é flexível e foca o desenvolvimento profissional de professores experientes. A investigação qualitativa baseou-se na análise descritivo-interpretativa das narrativas presentes em quatro atividades, realizadas durante o processo formativo, de quatro participantes. Foram analisados conhecimentos pedagógicos gerais, conhecimentos de conteúdo específico, conhecimentos pedagógicos do conteúdo, conhecimentos sobre formação e atuação docente e, por fim, conhecimentos sobre a função de gestor, de mentor e da escola. Como resultado, percebe-se que a base de conhecimentos atribuída ao mentor se assemelha à dos profissionais gestores e formadores de professores, ainda que a prática da mentoria e em sala de aula seja importante para que a base seja continuamente remodelada e aperfeiçoada para melhorar o desempenho do mentor e, possivelmente, dos professores iniciantes por ele acompanhados. Palavras-chave: Programa de Formação Online de Mentores; Identidade docente; Base de conhecimentos para o ensino ABSTRACTThis article aims to analyze the knowledge base of experienced teachers and participants of an Online Mentor Education Program from UFSCar Brazil and to answer the question: what specific, pedagogical and mentoring skills, that will assist the mentor to fulfill a new role, are evidenced by the experienced teachers participating of Online Mentor Education Program? This mentor training program has a flexible curriculum and focuses on the professional development of experienced teachers. The qualitative research was based on the descriptive and interpretative analysis of four narratives from four selected participants from a wider group and written during the training. It analyzed pedagogical knowledge, specific content knowledge, pedagogical knowledge content, knowledge about training and teaching practice and knowledge of the manager role, mentor and school. As results, the data analysis shows that the mentor knowledge base resembles the professional managers’ and teacher educators’. However, teaching and mentoring practice is important so that this knowledge base is continuously remodeled and improved, thus improving the mentors’ performance and, possibly, of beginning teachers accompanied by them.Keywords: Online Mentor Education Program; Teacher identity; Knowledge base for teaching
A dimensão afetiva na interação plurilingue: Dinâmicas de negociação de imagens e estereótipos na interação romanófona em chat
Authors: Melo-Pfeifer Sílvia , Araújo e Sá Maria Helena Almeida Beirão
Published: December 2017

Tendo em conta a relevância da Internet ao nível do contacto intercultural e plurilingue, e definindo-se os espaços de comunicação como lugares de emergência e de negociação de imagens acerca do Outro, analisaremos um corpus constituído por interações plurilingues romanófonas em chat, com vista ao estudo da dinâmica das imagens e estereótipos nessa situação de comunicação. Tentaremos desocultar e analisar barreiras à comunicação intercultural, algumas utopias acerca dela (em particular, o recurso a uma língua franca como solução para os problemas comunicativos) e ainda facilidades propulsoras da interação, como a relação afetiva com as línguas, os locutores e a situação de comunicação. A discussão dos dados permitirá evidenciar como as imagens e os estereótipos cruzados de uns locutores em relação aos outros, às suas línguas e culturas emergem na interação, como estimulam e alimentam a conversação e como desencadeiam momentos "felizes" de comunicação plurilingue.Palavras-chave: Comunicação eletrónica; Intercompreensão; Imagens; Estereótipos ABSTRACTGiven the importance of the Internet as a contact tool at an intercultural and multilingual level, and considering a definition of communication spaces as places where images about the Other emerge and are negotiated, we will analyze a corpus of plurilingual interactions in chat conversations (in Romance Languages), in order to study the dynamics of the images and stereotypes in this communication situation. We will attempt to uncover barriers to intercultural communication, expose some utopias about it (like the use of a lingua franca as a solution to communication problems) and discover the possibilities propelling interaction, such as an affective relationship with the languages, the speakers and the communication situation. Data discussion will allow us to demonstrate how crossed images and stereotypes of the speakers towards others, their languages and cultures emerge in the interaction, how they feed and stimulate conversation and how they trigger ‘happy’ moments of plurilingual communication.Keywords: Electronic communication; Intercomprehension; Images; Stereotypes
“ROLL OF STUDY HABITS ON ACADEMIC ACHIEVEMENT OF DIFFERENT STREAMS OF B.ED., STUDENTS.”
Authors: SINGH B. P.

In the era of globalization and technological revolution, education plays vital role in the acquisition of knowledge and skills that enable a person to increase the productivity of the nation and improve the quality of life. The social and economic development of a country is linked with student academic performance. The student performance plays an important role in producing best quality graduates who will become great leaders and give manpower for a country thus are responsible for the country’s economic and social development. (Ali et. al., 2009). The present study was carried out to determine the role of study habits on academic achievement of B.Ed. students of different streams. A sample of 400 B.Ed. students was taken from two govt. colleges and two private colleges of Bhiwani and Palwal district. Results indicate that a positive correlation exists between academic achievement and study habits, science students are better than commerce and arts students in their study habits. Female science students are even better than male science students.
A students learning is determined by the grade a student earns for a period of learning. Greater the grade of the student means that the student has learned a lot and hence, greater the academic achievement of the student. Academic achievement of the student is not related with only one variable. Academic achievement of the student is also related with age, year level, parents’ educational attainment, social status, number of siblings, birth order, IQ, gender, study attitude and study habits. Personal and environmental factors are responsible for academic achievement. Many studies say that learning is better acquired and mastered as soon as the learner attends to it. Gestalt psychology mentions the Law of Proximity referring to the way in which he tends to form groups according to the way they are spaced, with the nearer one’s being grouped together (Tria. et. al., 1998). As applied to learning, this refers to the closeness in space or in time. Further more, it explains why it is easier to remember recent events and hence more easily joined with the interest of the present in a common, Gestalt (Tria. et.al., 1998). In learning process, immediate and continuous drill work tend to enhance better academic achievement.

Published: December 2017

The concept of learning style has become an important area of educational research in recent times. The concept of learning styles has been defined as a certain specified pattern of behavior and performance according to which the individual approaches a learning experience, a way in which the individual takes in new information and develops new skills, and the process by which the individual retain new information or new skills. For example, an auditory learner learns best by listening; a visual learner does best with visual aids, where as a kinesthetic learner acquires knowledge through some physical activity, such as building a model , designing a project , or drawing a schematic. The terms ‘auditory learner’, ‘visual learner’ and’ kinesthetic learner’ are not categorical. These terms are just convenient way to learners with certain strengths or natural predominant tendencies. Most people have combination of these strengths or tendencies. There are three types of Learning Styles
