Applying Cognitive Linguistics to teaching English prepositions in the EFL classroom
Authors: Wijaya David , Ong Gabriella
Published: June 2018

This paper reports on a quasi-experimental study investigating the effect of cognitive linguistics-grounded instruction on learning the prepositions in, on, and at, which are known to pose tremendous difficulty to English language learners due to their language-specific features and polysemous nature. The participants (N = 44) were adolescent learners at a school in Indonesia. They were assigned into the cognitive group and the rule group. The cognitive group was presented with pictorial representations of the prepositions and cognitive tools used to motivate non-spatial uses, while the rule group was provided with rules. Participants’ performance on the three uses (i.e. spatial, temporal and abstract) was measured with pre-, post-, and delayed post-tests in a form of gap filling. The study yielded mixed results. The findings demonstrate that the cognitive group outperformed the rule group in the overall immediate and delayed post-tests. The cognitive group improved significantly in the immediate post-test; however, the positive effect did not last until the delayed post-test. On the other hand, the rule group gained a little in the immediate post-test, but the group’s performance decreased significantly in the delayed post-test. Although there was no indication of long-term effects of the cognitive instruction, the results still indicate a value of applying cognitive linguistics to teaching the prepositions, and thus lend support to the applicability of cognitive linguistic theory in second language instruction.
Lexical patterns in customary sayings
Authors: Jaafar Mohammad Fadzeli
Published: June 2018

Customary sayings are the traditional words delivered in the form of poetry and practiced in various social activities in Negeri Sembilan in marriage, family, criminal law and administration. Sudeen (1995) recorded that studies on customary sayings have been conducted from the early 20th century in the history of custom, marriage system, political system and the dispensation of inheritance.This study examines the content words and function words in customary sayings that have been categorized based on the semantic domain concept by Gliozzo (2006).  Based on the content words and function words, this study has identified the customary words in the corpus data. The results show that more function words were used in the customary sayings.  However, content words dominated the list of customary sayings, such as Datuk and custom. The function words 'nan' and 'dek' were found in all domains of the study namely, political, social and economic domains. These findings indicate that function words are not only grammatically functional, but also used to give an aesthetic impact through the articulation style of the local dialect.  On the other hand, the analysis of the content words shows that the use of customary words is influenced by the environment and culture of Adat Perpatih.
The reconceptualisation of knowledge base in the pre-service teacher education curriculum: Towards ELF pedagogy
Authors: Sakhiyya Zulfa , Agustien Helena I.R. , Pratama Hendi
Published: June 2018

This article examines “what will be taught” or the knowledge base demonstrated in the English language teacher education curricula by using the framework of English as a Lingua Franca. The need for enhancing the professionalism of English teachers in the ascendancy of English as a Lingua Franca (ELF) in Indonesia demonstrates a critical point where pre-service teacher education holds strategic roles. This epistemological turn needs to ensure that the teachers are devised with knowledge base as well as contextual approach suited to each particular educational environment. Fifteen Indonesian pre-service teacher education programmes were randomly selected and meta-analysed to aggregate the extent of reconceptualisation of the knowledge base provision by focusing on the curricula’s emphasis (linguistics and/or language proficiency) and the integration of socio-cultural perspective. Although these curricula cannot wholly represent cultural responsiveness and pedagogical practices, they could serve as sites concerning the values and knowledge held as important in the institution. We argue that there is a need to place a greater emphasis on the language proficiency that matches the ELF paradigm, as well as to reconceptualise the knowledge base to respond to the diverse Indonesian socio-cultural realities encountered by the recontextualising agents, the teachers. The reconceptualisation of knowledge base would foster greater awareness of sociocultural relativity and learning expectations of teaching ELF situated in the Indonesian educational context.
An intercultural study of euphemistic strategies used in Saudi Arabic and American English
Authors: Al-Khasawneh Fadi
Published: June 2018

People often use euphemistic utterances or expressions to avoid offensive or tabooed topics, to make them more implicit and considerate. This paper explores the euphemistic strategies used in Saudi Arabic and American English. The sample of this study includes 145 college students (78 Saudis and 67 Americans). A questionnaire adopted from Rabab’ah and Al-Qarni (2012) was used to collect the data of the present study. The results revealed various strategies used by the participants, such as deletion, synonyms, metaphor, understatement, part-for-whole, overstatement, and jargons. The most frequent strategies used by the Saudis were ‘part-for-whole’, ‘understatement’, and ‘general- for-specific’. The American participants tended to use ‘taboo words’, ‘general-for-specific’ and ‘synonyms’ more frequently than the other strategies. The findings also showed that there is no relationship between strategy choice and gender. The findings suggest that Saudi Arabic seems to use euphemistic strategies more than the Americans. These results could be referred to cultural and religious beliefs and values. The study recommends raising the awareness of euphemism strategies for more active communication.
Responding to the critics: Implementation of TBLT in Japan
Authors: Harris Justin
Published: June 2018

This paper outlines a qualitative study of 10 in-service teachers in Japan who use a task-based language teaching (TBLT) approach in their language classrooms. The study investigates the reasons why these teachers began using TBLT, their beliefs about the advantages and disadvantages of implementing TBLT, and whether or not they agree with common criticisms levelled at TBLT for use in foreign language classrooms in Japan and Asia in general. Critics argue that TBLT is not suitable for many language learning situations, explaining that students are used to more ‘traditional’ teacher-centered language classes and that they prefer more ‘passive’ approaches. Such criticisms also hold that TBLT is not able to adequately prepare students for the high-stakes tests that are used for secondary school and university entrance purposes. The results from interviews with these 10 teachers suggest that they reject many of these criticisms, and are in fact successfully using TBLT to develop both language ability and motivation in their students. At the same time, the teachers noted that there may be a need to use a ‘weaker’ form of TBLT with beginner students, or with those used to more passive styles of learning. They also highlighted the importance of heavily scaffolding tasks in such cases. Finally, a number of the teachers discussed the need for the development of more TBLT related materials, both for students and teachers.
EFL teachers’ motivation and competence in an Indonesian context as assessed within the framework of Maslow’s and Herberg’s theories
Authors: Tambunan Anna Riana Suryanti , Hamied Fuad Abdul , Sundayana Wachyu
Published: June 2018

Using regression and descriptive analyses, this research was carried out to measure the nature of teachers’ motivation as indicated by their job commitment and satisfaction, which was then used to predict the EFL teachers’ competence. The participants were 42 high school English teachers from both public and private schools in Binjai, North Sumatera Province. Likert-type inventory on teachers’ motivation, with items focused on job commitment and job satisfaction, and a fact-based, multiple choice assessment of teaching competences were employed. It was found that motivation as indicated by both teachers’ commitment and satisfaction could have a significant impact on their competence. For the success of any school in achieving its predetermined goals, committed and satisfied human resources are therefore considered as the most critical assets. Thus, fostering commitment and satisfaction among teachers is essential because teachers, who are highly committed and satisfied, would tend to stay longer, perform better, and are actively involved in classroom, school and social activities.
After Planning, the Production of Radical Social Space in Barcelona: Real-Estate Financial Circuit and (De Facto) Right to the City
Authors: Jiménez-Pacheco Pedro
Published: June 2018

This article is based on the premise that it is possible to apply Henri Lefebvre’s critical-theoretical apparatus to complex urban processes as a pedagogical case study. From previous knowledge of Lefebvrian thought, the article provides an overview of what Lefebvre called “the science of the use of social space”, supported by a transdisciplinary methodological plurality. The starting point is that neoliberal social space is produced, prepared, and led to the imminent urban post-neoliberalism, in the midst of this movement, a sophisticated planning system appears, with the old promise of service tradition, egalitarian ethics and pragmatic orientation. But in practice, it only reproduces the impotence of being inside a wave of localized surplus-benefits that expels human residues, avoiding any reaction. The Lefebvrian apparatus and a part of its theoretical tradition guide the research on Barcelona as a paradigm of global real-estate violence. This urban phenomenon is examined in central Barcelona, in order to rescue it from the pessimism of its own inhabitants, from the harsh perception that urban centrality no longer reproduces life. In this way, the article puts into operation an analytical tool designed to sabotage the real-estate circuit through a renewed right to the production of radical social space.
On Architectural Space and Modes of Subjectivity: Producing the Material Conditions for Creative-Productive Activity
Authors: Koch Daniel
Published: June 2018

This article discusses extended implications of Lefebvre’s The Production of Space in the context of contemporary global neoliberalism, by focus on its presence in architectural space as lived space and spatial practice. The main discussion concerns Lefebvre’s concepts of abstract space, in relation to Felix Guattari’s three ecologies, and the Aristotelean triad of aisthesis, poiesis and techné. The focus here concerns material architectural space and its relation to modes of subjectivity, especially creative-productive versus consuming subjectivities. The argument begins by elaborating on an understanding of abstract space as present in material architectural space as pervasive processes of disassociation of materiality and labor, and proceeds to through these concepts discuss modes of subjectivity—the dependence of abstract space on subjects as consumers—and the way this relates to challenges of sustainability. It further points to the importance of architectural space considered as built material environment for creative-productive modes of subjectivity which challenge abstract space and in extension consumer society, by offering potential dispositions that set subjects in a different relation to the world.
Verbete toponímico: microestruturas para hidrônimos / Toponymic Entry: Microstructures for Hydronyms
Authors: Castiglioni Ana Claudia
Published: June 2018

Resumo: O objeto de estudo da Toponímia são os topônimos, analisados sob diferentes perspectivas, como a sua origem, sua significação, sua transformação, sua classificação taxionômica. Neste artigo será apresentada a proposta de três modelos de microestrutura para verbetes toponímicos a partir dos pressupostos teóricos da Toponímia e da Terminologia: um para verbetes cujas entradas designam conceitos relativos a elementos hidrográficos e a conceitos-chave do conjunto toponímico, outro para a constituição dos verbetes que têm como entradas os sintagmas toponímicos e um terceiro remissivo. O corpus que serviu como base para formulação dos modelos foi o repertório das unidades léxicas que designam o nome dos elementos geográficos referentes à água, arroio, baía, cabeceira, cabo, cachoeira, canal, catarata, corixão, corixo, córrego, foz, lago, lagoa, nascente, represa, riacho, ribeira, ribeirão, rio, riozinho, salto, sanga, vazante e volta. Esses hidrônimos foram obtidos no banco de dados do projeto Atlas Toponímico do Estado de Mato Grosso do Sul – ATEMS. As microestruturas propostas poderão ser opção para subsidiar a elaboração de dicionários toponímicos que, além de registrarem os nomes próprios com sua respectiva localização e causas que motivam a nomeação, também contribuem para o resgate e o registro social, histórico e cultural de uma região.Palavras-chave: Toponímia; Terminografia; topônimos; microestrutura.Abtract: The object of study of Toponymy are toponyms, seen from different perspectives such as their origin, meaning, changes, and categorization. This paper will present the proposal of three microstructure models for toponymic entries based on the theoretical assumptions of Toponymy and Terminography: one for entries whose input word designate concepts related to hydrographic elements and key concepts of the toponymic set, another for the constitution of entries that have as input word the toponymic phrases and a third remissive. The corpus that served as basis for the formulation of the models was the repertoire of lexical units that designate the name of the geographic elements referring to water, brook, bay, headland, cable, waterfall, channel, cataract, corixão, corixo, stream, estuary, lake, lagoon, spring, dam, creek, stream, creek, river, sanga, ebb and curve. These hydronyms were obtained from the Atlas Toponímico do Estado de Mato Grosso do Sul – ATEMS. The proposed microstructures may be an option to subsidize the development of toponymic dictionaries that, in addition to registering proper names with their respective location and causes that motivate their nomination, also contribute to the rescue and social, historical and cultural registration of a region.Keywords: Toponymy; Terminography; toponyms; microstructure.

O mito de Pelé, ou: 'um desvendamento do Ser'
Authors: Van Loyen Clemens
Published: June 2018

Minha contribuição parte de um ensaio pouco conhecido de Vilém Flusser, intitulado “Peleologia”, publicado no Suplemento Literário de O Estado de São Paulo em 04 de julho de 1964. Este ensaio tem um lugar de destaque no pensamento flusseriano. Argumento que ele está no limiar do próprio esclarecimento sobre o conceito de ‘pós-história’, como será tratado dois anos mais tarde no ensaio “Do Programa”, no qual Flusser proclama, pela primeira vez, “o fim da história”. Meu artigo visa elucidar as teias de pensamento, a dissolução e o surgimento de conceitos na obra flusseriana. Em Pelé, por exemplo, Flusser reconhece uma nova possibilidade de existência, o assim chamado ‘novo homem’, que seria também um modelo de vida para os brasileiros.

Este artigo analisa A turma da Rua Quinze (1989), de Marçal Aquino, e Aventura no império do Sol (1989), de Silvia Cintra Franco, romances originariamente publicados pela Coleção Vaga-Lume. Em ambos observamos que o jogo – representado pelo futebol e o voleibol – está incorporado ao cotidiano e mesmo ao patrimônio cultural dos personagens, como “elemento estruturante” (CORNELSEN, 2012) de uma educação para vida, que envolve uma ética das relações pessoais e a formação para a sobrevivência, na medida em que mesmo pertencendo a um time, os personagens passam a atuar como uma “comunidade luminosa” (FIGUEIREDO, 2016).

FFF versão 2.0.: Uma possível actualização dos três Fs do Estado Novo
Authors: Fernandes Cláudia
Published: June 2018

Em Portugal, ao longo da contemporaneidade, a relação entre política e futebol foi tendo diversas abordagens, servindo diferentes interesses e veiculando várias causas. A associação comum dos FFF: Fado, Fátima e Futebol ao Estado Novo ficou bastante enraizada na memória colectiva como uma forma de manipulação do povo, mas na verdade foi mais do que isso, pois acabou por ser uma manobra útil de política internacional. Passados estes anos todos, a improvável conjugação dos três Fs voltou a formar-se de modo completamente tão surpreendente como vitoriosa. No entanto, até que ponto isso poderá espelhar-se na cena política actual, poderá falar-se de uma nova versão do velhinho mote Fado, Fátima e Futebol ou será que estamos diante de um novo paradigma cultural? Houve aproveitamento político ou será que o sucesso dos FFF, nomeadamente o futebol, reflectem um cenário político novo?
'A luta pelo Passe Livre': das politische Handeln des brasilianischen Fußballers Afonso Celso Garcia Reis in den 1960er- und 1970er-Jahren
Authors: Knoth Sebastian
Published: June 2018

Este estudo analisa a militância política do jogador brasileiro Afonso Celso Garcia Reis (Afonsinho) e sua luta pelo Passe Livre durante as décadas de 1960 e 1970. Afonsinho, estreante no futebol brasileiro profissional durante a segunda metade da década de 1960, vivenciou uma radical mudança nos padrões de treinamento, a qual impunha um modelo de disciplina militar. Esse, não tolerava o comportamento analisador e crítico de Afonsinho que sofreu, por tal motivo, um série de restrições. Em reação ás restrições, Afonsinho começou a luta pelo Passe Livre, ou seja, pela liberação do seu passe de jogador que se tornou uma ação simbólica contra as repressões da ditadura militar no Brasil. A repercussão social deste conflito foi um fator político importante naquele momento e ultrapassou em muito os limites do mundo do futebol.

Micronucleus is an abnormal structure in eukaryotic cells. It is the result of various physical and chemical factors,such as radiation and chemical drugs acting on dividing cells. It is generally believed that micronuclei are originatedin backward chromosomes and fragments that have lost centromere and are formed at the end of mitosis. However,other experiments suggest that interphase cells can also form micronuclei. In this study, human peripheral bloodlymphocytes were cultured in vitro and cyclophosphamide 20 ug/ml was injected at specifi c times of the cell cycle toobserve the relationship between micronuclei formation and cell cycle. The experimental results confi rmed that thecell cycle micronucleus formation.

Brazil is gaining its momentum in pharmaceutical development
Authors: Ruenis Ana Paula , Filho João Massud
Published: June 2018

Brazil is one of the world´s largest economies and pharmaceutical markets, having the Brazilian government as an important purchaser. There are strong local companies that have grown sustainably after the introduction of generics and are investing in both incremental and radical innovation. However, research and development (R&D) expenditures are still modest; this could be explained by a combination of economic and political uncertainty in the past few years and a bureaucratic, complex regulatory framework. New regulations, efforts to reduce ethical and regulatory review timelines, and a Senate bill aimed to accomplish that goal should constitute the definitive regulatory landmark for boosting clinical research. In addition to government investments they have given a breath of relief in the market, as Brazil is trying to, once again, gain momentum as a “must-go” country for clinical development. Non-profit associations such as the Brazilian Society of Pharmaceutical Medicine (Sociedade Brasileira de Medicina Farmacêutica-SBMF), the Brazilian Association of CROs (Associação Brasileira de Organizações Representativas de Pesquisa Clínica-ABRACRO), the Brazilian Clinical Research Alliance (Aliança Pesquisa Clínica Brasil), amongst others, helped to give the impulse to trigger such changes. It is time to invest heavily in developing educational programs to address the growing need for clinical development scientists and physicians.

Study of Formation of Oxide Nanostructures on the Surface of Radiation-oxidated Aluminum
Authors: Gadzhieva Nushaba Nubarak
Published: June 2018

Reflection IR spectroscopy, atomic force microscopy (AGM), and electrophysical measurements were used to investigate the formation of surface oxide nanostructures during the radiation oxidation of metallic aluminum in contact with water. It is revealed that the radiation modification of the surface relief is accompanied by the formation of oxide nanolayers, the defectiveness of which is determined by the irradiation time. It is shown that the formation of oxide nanolayers in the region of absorbed dose (0.5-120 kGy) occurs in three stages, which is accompanied by a decrease in electrical conductivity by 5 orders and an increase in the thickness of the oxide layer by an order of magnitude. The role of surface intermediate-active particles in the formation of oxide nanostructures is considered.

Study on the influence of the springback on the hole expansion ratio characterization
Authors: Mendiguren Joseba , Zubia Biotza , Agirre Julen , Galdos Lander , SaenzdeArgandona Eneko
Published: June 2018

Material formability has become one of the main problems, together with the springback, when stamping high added-value components for the automotive industry. The pursuit of weight reduction has led to higher strength alloys which show a lower formability. Among the different formability criteria (e.g. necking, edge strain, fracture and radius cracks) the edge strain is starting to be a critical aspect on the process planning stage. In order to characterise this criteria, the hole expansion ratio (HER) is conducted under the ISO 16630 standard. In the last years, multiple authors have analysed the HER of different alloys and its dependency on different process variables i.e. cutting method, test speed, material strength. However, the influence of the springback phenomenon on the test result has not been previously analysed. In this work, the influence of the springback on the HER values has been analysed for a mild steel DX54D and a third generation steel Fortiform1050 with a novel measuring technique. From the obtained results, it can be stated that the springback has a critical influence on the characterised HER value, mainly for the third generation steel, leading to differences of about 40% on the HER limits.

Geotechnical assessment of the foundation including engineering geological investigations are essential for important civil structures to provide permanent data set for geological interpretations and for recommendations of suitable engineering measures for the improvement of the foundation. Yaragol Gravity Dam for drinking water is being constructed across Markandaya river in Karnataka State of India. Engineering geological mapping on 1:200 scale was carried out for Housing Chamber of Yaragol Gravity Dam to evaluate the design basis foundation parameters. 2 m x 2 m grids were prepared for mapping of the floor. Based on the field observations and evidences, it was found that the floor area consists of foliated gneiss and granite. No evidence of faulting or shearing was observed on the surface of the floor area. Geotechnical assessment of the foundations was done on the basis of detailed engineering geological mapping and laboratory test results. Classification of rock mass using Rock Mass Rating (RMR) of Bieniawski (1989) has been attempted and based on investigations recommendations for the treatment of foundation were given. Rock type and Rock Mass Rating (RMR) methods were used for assessing the safe bearing pressure of the foundation. Consolidation grouting up to 6 m depth in the foundation using primary at 6 m spacing and secondary holes at 3 m spacing was recommended. After detailed investigations it was found that, the foundation is suitable to locate a housing chamber.
