The significance of beige and brown fat in humans
Authors: Kiefer Florian W
Published: May 2017

Promotion of brown adipose tissue (BAT) activity or browning of white adipose tissue has shown great potential as anti-obesity strategy in numerous preclinical models. The discovery of active BAT in humans and the recent advances in the understanding of human BAT biology and function have significantly propelled this field of research. Pharmacological stimulation of energy expenditure to counteract obesity has always been an intriguing therapeutic concept; with the identification of the specific molecular pathways of brown fat function, this idea has now become as realistic as ever. Two distinct strategies are currently being pursued; one is the activation of bone fide BAT, the other is the induction of BAT-like cells or beige adipocytes within white fat depots, a process called browning. Recent evidence suggests that both phenomena can occur in humans. Cold-induced promotion of BAT activity is strongly associated with enhanced thermogenesis and energy expenditure in humans and has beneficial effects on fat mass and glucose metabolism. Despite these encouraging results, a number of issues deserve additional attention including the distinct characteristics of human vs rodent BAT, the heterogeneity of human BAT depots or the identification of the adipocyte precursors that can give rise to thermogenic cells in human adipose tissue. In addition, many pharmaceutical compounds are being tested for their ability to promote a thermogenic program in human adipocytes. This review summarizes the current knowledge about the various cellular and molecular aspects of human BAT as well as the relevance for energy metabolism including its therapeutic potential for obesity.

Authors: Ugarelli Alejandra , Evangelista-Vargas Shirley , Santiani Alexei
Published: May 2017

El objetivo del presente trabajo fue determinar el porcentaje de integridad acrosomal en espermatozoides epididimarios de alpaca utilizando Arachis hypogaea (PNA) y Pisum sativum (PSA), conjugadas con isoticionato de fluoresceína (FITC). Se recolectaron 45 testículos de alpaca obtenidos del Camal Municipal de Ninacaca, provincia de Pasco (Perú) y se utilizaron 29 muestras recuperadas de la cola del epidídimo con motilidad mayor de 30% y concentración mayor de 50x106 espermatozoides/ml. Los espermatozoides fueron suspendidos con 1 ml de solución Tris base, se lavaron por centrifugación a 600 g por 8 min y los pellets fueron re-suspendidos en 300 μl de PBS. Cada muestra fue dividida en dos alícuotas e incubadas por 8 min a 38 °C con FITC-PNA (0.5 μg/ml) o FITC-PSA (2.5 μg/ml), junto con un marcador de vitalidad (ioduro de propidio [PI], 0.5 μg/ml). Las muestras fueron evaluadas mediante citometría de flujo, utilizando un láser de excitación de 488 nm y canales detectores de emisión de fluorescencia de 505-560 nm (Canal 02 para FITC) y de 642-740 nm (Canal 05 para PI). Los espermatozoides que emitieron fluorescencia verde en el Canal 02 fueron considerados con daño acrosomal, mientras que los que emitieron fluorescencia roja en el Canal 05 fueron considerados muertos. Se obtuvo 59.17 ± 4.84 y 61.13 ± 4.35% de espermatozoides vivos con integridad acrosomal para FITC-PNA y FITC-PSA, respectivamente. Los resultados presentan un indicador de la integridad acrosomal en espermatozoides epididimarios de alpaca, que podría constituir una base para el estudio de la fisiología espermática en esta especie.
Walsh-Lebesgue points and restricted convergence of multi-dimensional Walsh-Fourier series
Authors: Weisz Ferenc
Published: May 2017

A new concept of Walsh-Lebesgue points is introduced for higher dimensions and it is proved that almost every point is a modified Walsh-Lebesgue point of an integrable function. It is shown that the Walsh-Fejér means σnf of a function f ∈ L1[0, 1)d converge to f at each modified Walsh-Lebesgue point, whenever n→∞ and n is in a cone. The same is proved for other summability means, such as for the Weierstrass, Abel, Picard, Bessel, Cesàro, de La Vallée-Poussin, Rogosinski and Riesz summations.
Persistence
Authors: Saferstein Barry
Published: May 2017

This study identifies the components and effects of professional persistence by analyzing video recordings of teachers’ responses to students during genetics learning activities in high-school biology courses. It describes types of persistence that, as responses to digressive questions and comments, support standard communicative agendas embedded in professional culture. Examining persistence elucidates how specific components of interaction sustain conventions of professional culture and consolidate professional authority. The discussion extends the findings to consider how types of persistence apply more generally to various types of professional–client encounters, and how they affect clients’ participation and access to useful information.
Untersuchungen zur Zinkkonzentration in unterschiedlichen Probenmedien von Milchkühen und Ableitung von Referenzwerten
Authors: Schmidt Fabian , Müller Anja-Elvira , Staufenbiel Rudolf , Pieper Laura
Published: May 2017

Gegenstand und Ziel: Zink spielt bei vielen Körperfunktionen eine Schlüsselrolle und ist für die Gesundheit und Fruchtbarkeit von enormer Bedeutung. Die Beurteilung der Zinkversorgung kann durch Analyse von Blut-, Harn- oder Haarproben erfolgen. Ziel der Studie war, Referenzwerte für die unterschiedlichen Probenmedien und Laktationszeitpunkte für die Herdenuntersuchung deutscher Milchviehherden zu bestimmen. Material und Methoden: Daten von 1515 Herden, die im Rahmen der Bestandsbetreuung der Klauentierklinik der Freien Universität Berlin zwischen 1995 und 2012 beprobt wurden, gingen in die Analyse ein. Die Zinkkonzentration wurden in Serum, Plasma, Vollblut, Haar und Harn der Poolproben von 7–10 Tieren pro Gruppe bestimmt. In Herden mit mehr als 200 Tieren wurden Kühe aus fünf Gruppen beprobt (8–3 Wochen ante partum [a. p.], 3–0 Wochen a. p., 0–1 Wochen post partum [p. p.], 3–5 Wochen p. p. und 15–18 Wochen p. p.). In Herden mit weniger als 200 Tieren beschränkte sich die Beprobung auf vier Gruppen (8–3 Wochen a. p., 3–0 Wochen a. p., 0–5 Wochen p. p. und 6–20 Wochen p. p.). Ergebnisse: Die Korrelationen zwischen den Zinkkonzentrationen in den Probenmedien variierten zwischen r = 0,001 (Vollblut und Harn) und r = 0,75 (Serum und Plasma). Die Zinkkonzentrationen in Serum und Plasma änderten sich schnell und folgten einer Laktationsdynamik mit den niedrigsten Werten um die Kalbung. In Vollblut und Haar änderten sich die Zinkkonzentrationen langsam und folgten der Laktationsdynamik zeitverzögert mit niedrigsten Werten einige Wochen nach der Kalbung. Referenzwerte für Poolproben für die unterschiedlichen Probenmedien und Laktationsstadien werden vorgeschlagen. Schlussfolgerungen und klinische Relevanz: Für die Diagnostik in unterschiedlichen Probenmedien und zu verschiedenen Laktationszeitpunkten müssen verschiedene Referenzwerte angewendet werden. Um mittels wiederholter Untersuchungen Veränderungen der Zinkversorgung beurteilen zu können, sollten dasselbe Probenmedium und derselbe Laktationszeitpunkt herangezogen werden.
Epidemiologie und Prophylaxe der Leptospirose beim Hund
Authors: Llewellyn Julia-Rebecca , Hartmann Katrin , Bergmann Michèle
Published: May 2017

Die Leptospirose ist eine Zoonose mit steigender Prävalenz bei Hunden und Menschen in Deutschland. Die verschiedenen Leptospiren-Serovare haben unterschiedliche Pathogenität. Auch gesunde infizierte Hunde scheiden Leptospiren über den Urin aus und stellen somit ein Infektionsrisiko für Menschen und andere Tiere dar. Die Impfung ist die wichtigste Maßnahme zum Schutz; sie verhindert nicht nur die Krankheit beim Hund, sondern vermindert auch die Ausscheidung von Leptospiren über den Urin. Für einen möglichst umfassenden Impfschutz sollten tetravalente Impfstoffe verwendet werden, die Serovare der in der Region relevanten Serogruppen enthalten. Die Verbreitung der Erreger kann durch die weite Anwendung dieser Impfstoffe reduziert werden. Eine ausführliche Besitzeraufklärung über das zoonotische Potenzial der Leptospirose und geeignete Hygienemaßnahmen beim Umgang mit infizierten Hunden und Hundeurin sind essenziell.

Published: May 2017

ABSTRACT The adequate time for carrot seed harvest influences its physiological quality. The objective of this study was to evaluate physiological, anatomical and histochemical changes in carrot seeds harvested at different stages of development and to establish the most appropriate harvest time. Secondary umbels were harvested at 14, 21, 28, 35, 42, 49, 56 and 63 days after anthesis (DAA). For seed anatomical and histochemical characterization, sections were stained with Toluidine blue stain, Xylidine Ponceau, Lugol’s iodine, Sudan Black B and submitted to polarized light. Seed moisture content, seed dry matter, germination, first count, emergence percentage and emergence speed index of seedlings were evaluated. Cultivar Brasília carrot seeds at 14 DAA are in cell division and expansion. In addition, as lipids were identified in the endosperm, despite the seed low dry matter. At 21 DAA, reserve substances such as protein and starch were also identified. Along the seed development process, deposition of lignin occurs in the endocarp cells, and this collapsed lignified layer represents the resistance layer of the seeds. Physiological maturity, represented by the maximum dry matter accumulation, occurs at 35 DAA, with the endosperm occupying almost all volume of seeds, the embryo occupying a small cylindrical region and the integument showing a single layer of cells. At this time, the seeds presented 56% moisture content and the color of the pericarp is green-yellow. Maximum seed germination and vigor occurred at 30 DAA, just before physiological maturity was reached (35 DAA). Thus, the ideal time to harvest the seeds of cultivar Brasília is from 30 DAA, where the seeds have maximum physiological quality.

Published: May 2017

ABSTRACT Although there are evidences that the proper supply of mineral nutrients to plants relieves water stress, little is known on the approach of how the drought affects the absorption and accumulation of nutrients by distinct sugar cane genotypes, or in different parts of a same plant. Thus, the objective of this study was to determine the content and accumulation of N, P and K in the aerial part of plant from three genotypes of sugar cane, submitted to three water potentials in the soil, and check the relationship of these variables with the tolerance of plants to prolonged drought. In order to access this objective, an experiment under greenhouse conditions, comprised by a fatorial 3 × 3, in a randomized block design, and four replicates was carried out. After 90 days from treatment imposition, the plant transpiration rate, plant dry mass, concentration of N, P and K were determined in leaves and culms, as well as in total plant shoot were measured. It was found that tolerance to drought in sugar cane is related to higher levels of N and K in the leaves and stems, and larger accumulations of K and P in the plant shoot. There is high positive correlations among accumulation of N, P and K in the plant shoot and dry matter production by plants submitted to drought. There are intermediate correlations among plant transpiration and nutrient uptake by plants under drought. Plants of the genotype SP81-3250 are more tolerante to prolonged drought, than the RB855453 and IACSP95-5000 plants.
Microbial additives in the composting process

Published: May 2017

ABSTRACT Composting is the process of natural degradation of organic matter carried out by environmental microorganisms whose metabolic activities cause the mineralization and partial humification of substances in the pile. This compost can be beneficially applied to the soil as organic fertilizer in horticulture and agriculture. The number of studies involving microbial inoculants has been growing, and they aim to improve processes such as composting. However, the behavior of these inoculants and other microorganisms during the composting process have not yet been described. In this context, this work aimed to investigate the effects of using a microbial inoculum that can improve the composting process and to follow the bacterial population dynamics throughout the process using the high-resolution melt (HRM) technique. To do so, we analysed four compost piles inoculated with Bacillus cereus, Bacillus megaterium, B. cereus + B. megaterium and a control with no inoculum. The analyses were carried out using samples collected at different stages of the process (5th to 110th days). The results showed that the bacterial inocula influenced the process of composting, altering the breakdown of cellulose and hemicelluloses and causing alterations to the temperature and nitrogen levels throughout the composting process. The use of a universal primer (rDNA 16S) allowed to follow the microbial succession during the process. However, the design of a specific primer is necessary to follow the inoculum throughout the composting process with more accuracy.

Published: May 2017

RESUMO Em contraste com vários outros estados brasileiros, apenas recentemente o Mato Grosso do Sul iniciou o inventário organizado de sua avifauna. Relacionamos 630 espécies de aves para o Mato Grosso do Sul, pertencentes a 26 ordens e 74 famílias, que corresponde a 34% da avifauna ocorrente no Brasil. Cerca de 90% dessas espécies apresentam registros comprobatórios de ocorrência no estado conforme as normas propostas pelo CBRO. As demais ainda aguardam documentação comprobatória adequada. Quarenta e cinco espécies foram incluídas na lista terciária por apresentarem problemas de documentação comprobatória devido à ausência de circunstanciação e distribuição incompatível. A grande diversidade de fitofisionomias e paisagens sob influência dos biomas Cerrado, Pantanal, Chaco, Bosques Chiquitanos e Mata Atlântica são responsáveis em parte, pela diversidade de espécies ocorrentes no Mato Grosso do Sul. No entanto, várias dessas fitofisionomias e paisagens já foram suprimidas e/ou alteradas pela pecuária e principalmente monoculturas ( Pinus, Eucalyptus e cana-de-açúcar). Trinta e sete espécies de aves ocorrentes no estado encontram-se presentes em listas de espécies ameaçadas de extinção em âmbito global e/ou nacional. Ainda existem grandes lacunas de conhecimento sobre a avifauna sul-matogrossense, notadamente no Pantanal do Paiaguás e em regiões limítrofes com o estado de Goiás e países como Paraguai (Chaco) e a Bolívia (Bosques Chiquitanos). Instituições como Embrapa Pantanal e Universidade Federal de Mato Grosso do Sul, bem como o trabalho de consultores ambientais e observadores de aves foram relevantes no avanço do conhecimento sobre a avifauna no estado. Grande parte dos museus institucionais no exterior abriga exemplares coletados no Mato Grosso do Sul, dentre os quais se destacam o Museum of Comparative Zoology (Cambridge, EUA), o American Museum of Natural History (Nova York, EUA), o The Field Museum of Natural History (Chicago, EUA) e o National Museum of Natural History (Washington, DC, EUA). No Brasil as principais coleções que guardam material ornitológico sul-matogrossense são o Museu de Zoologia (USP, São Paulo), o Museu Nacional (UFRJ, Rio de Janeiro) e o Departamento de Zoologia da Universidade Federal de Minas Gerais (DZUFMG, Minas Gerais).

Published: May 2017

Summary Introduction: Solid pseudopapillary tumor of the pancreas (SPTP) is a rare neoplasm of low malignant potential with uncertain behavior, diagnosed mainly in young women. Method: Our report comprises a series of cases of SPTP reviewed retrospectively, highlighting clinical, tomographic and immunohistochemical features, treatment performed and outcomes. Results: Thirteen patients were found to have pancreatic [solid] masses on computed tomography scan measuring a mean diameter of 8.8 cm. All patients underwent complete surgical excision. Immunohistochemistry confirmed diagnosis in all cases. Conclusion: SPTP occurs more frequently in young women. Diagnostic suspicion lies on the finding of a bulky, solid and cystic pancreatic mass. Imaging findings might provide diagnostic information before resection. Conservative approaches can be used in selected cases and survival rates are usually excellent following complete resection.

Summary Introduction: Virus surveillance strategies and genetic characterization of human parvovirus B19 (B19V) are important tools for regional and global control of viral outbreak. In São Paulo, Brazil, we performed a study of B19V by monitoring the spread of this virus, which is an infectious agent and could be mistakenly reported as a rash and other types of infection. Method: Serum samples were subjected to enzyme immunoassay, real time polymerase chain reaction, and sequencing. Results: From the 462 patients with suspected cases of exanthematic infections, the results of the 164 serum samples were positive for B19V immunoglobulin M. Among these cases, there were 38 patients with erythema infections and B19-associated with other infections such as encephalitis, hydrops fetalis, chronic anemia, hematological malignancies. These samples were sequenced and identified as genotype 1. Conclusion: This study showed patients with infections caused by B19V and sequencing genotype 1. Continuous monitoring is necessary to detect all known genotypes, and the emergence of new genotypes of these viruses for case management in public health control activities.

Summary Introduction: Obesity refers to the accumulation of fatty tissues and it favors the occurrence of oxidative stress. Alternatives that can contribute to body weight reduction have been investigated in order to reduce the production of reactive oxygen species responsible for tissue damage. The aim of the current study was to assess whether the oxidant and antioxidant markers of obese women before and after bariatric surgery were able to reduce oxidative damage. Method: We have assessed 16 morbidly obese women five days before and 180 days after the surgery. The control group comprised 16 non-obese women. Levels of thiobarbituric acid-reactive substances, carbonylated proteins, reduced glutathione and ascorbic acid were assessed in the patients' plasma. Results: Levels of lipid peroxidation and protein carbonylation in the pre-surgical obese women were higher than those of the controls and post-surgical obese women. Levels of reduced glutathione in the pre-surgical obese women were high compared to the controls, and declined after surgery. Levels of ascorbic acid fell in the pre--surgical obese women compared to the control and post-surgical obese women. Conclusion: Body weight influences the production of reactive oxygen species. Bariatric surgery, combined with weight loss and vitamin supplementation, reduces cellular oxidation, thus reducing tissue damage.

Published: May 2017

Resumo Este artigo tem como objetivo discutir a relação entre a ação e a produção de signos em atividades de modelagem matemática e o conhecimento dos alunos. Para delimitar o objeto de análise tratamos do conceito retomado por Peirce ao longo de seus trabalhos: a semiose. Considerando elementos relativos ao entendimento de modelagem matemática e à luz de aspectos da teoria peirceana, olhamos para o desenvolvimento de atividade de modelagem realizado por alunos de um curso de Química durante aulas de CDI. A análise da ação e produção de signos na atividade indica que a semiose, como ação que envolve signo, objeto e interpretante, não é limitada. Em vez disso, esta ação e produção revelam que fenômeno e Matemática são indissociáveis e que parece se configurar como uma rede em que signos são produzidos ou acionados pelo conhecimento e também geram novo conhecimento. Nesta rede, podemos caracterizar uma estrutura que associa conhecimento matemático, conhecimento sobre o problema em estudo e conhecimento tecnológico.
DNA Polymerase ε Deficiency Leading to an Ultramutator Phenotype: A Novel Clinically Relevant Entity
Authors: Castellucci Enrico , He Tianfang , Goldstein D. Yitzchak , Halmos Balazs , Chuy Jennifer
Published: May 2017

Deficiencies in DNA repair due to mutations in the exonuclease domain of DNA polymerase ε have recently been described in a subset of cancers characterized by an ultramutated and microsatellite stable (MSS) phenotype. This alteration in DNA repair is distinct from the better-known mismatch repair deficiencies which lead to microsatellite instability (MSI) and an increased tumor mutation burden. Instead, mutations in POLE lead to impaired proofreading intrinsic to Pol ε during DNA replication resulting in a dramatically increased mutation rate. Somatic mutations of Pol ε have been found most frequently in endometrial and colorectal cancers (CRC) and can lead to a unique familial syndrome in the case of germline mutations. While other key genomic abnormalities, such as MSI, have known prognostic and treatment implications, in this case it is less clear. As molecular genotyping of tumors becomes routine in the care of cancer patients, less common, but potentially actionable findings such as these POLE mutations could be overlooked unless appropriate algorithms are in place. We present two cases of metastatic CRC with a POLE mutation, both of which are ultramutated and MSS. The basic biochemical mechanisms leading to a unique phenotype in POLE deficiency as well as challenges faced with interpreting the genomic profiling of tumors in this important subset of patients and the potential clinical implications will be discussed here.
Effects of curing temperature on the hydration of GGBS concrete and the use of electron microscope particle analysis
Authors: Tang Kangkang , Wilkinson Stephen , Beattie Greg
Published: May 2017

It is a common concern that ground granulated blast-furnace slag (GGBS) blended CEM I concrete lacks sufficient early-age strength, which may prevent its application in cast-in-place structural concrete. This has been identified in the present study through GGBS activity index tests and compressive strength tests of GGBS blended concrete specimens. Current codes for GGBS used in concrete require a minimum early-age hydraulic activity and a specific surface area. The particle size distribution (PSD) of GGBS can also affect the physical and mechanical properties of concrete, but this cannot be sufficiently addressed by the standard testing methods. This paper proposes a quantitative assessment method which can quickly determine the particle shape and PSD of CEM I cement and GGBS samples based on electron microscope image analysis. This method of assessment offers the potential to work as an important supplementary method to the existing testing methods adopted by the cement industry. In addition to the particle shape analysis, CEM I and GGBS samples were also characterised based on isothermal calorimetry, scanning electron microscopy (SEM) and X-ray diffraction (XRD) tests. These tests were conducted at 20°C and 38°C curing to investigate the effect of curing temperatures.
Feasibility of specialty cement possessing improved bond properties
Authors: Assaad Joseph Jean
Published: May 2017

Reported attempts to develop specialty cement possessing improved bond and tensile properties resulting from inter-grinding elastomeric styrene–butadiene rubber (SBR) latexes during clinker processing are limited. Such types of ready-to-use cement would be of particular interest for repair and precast applications as well as for adhesive and protective cementitious materials requiring enhanced bond to existing substrates. The test results obtained in this work showed that cement processed in the presence of SBR is characterised by higher workability and improved flexural and pull-off bond strengths, but exhibits reduced efficiency of clinker grindability and compressive strength development. For SBR addition rates of less than 0·3%, the incorporation of an alkanolamine-based grinding aid (GA) was found to compensate for grindability and compressive strength losses while maintaining cement properties to ASTM C 465 requirements. The increases in flexural and pull-off strengths of cement inter-ground with combinations of SBR and alkanolamine-based GAs were higher than those achieved when the same SBR concentration was added as a post-addition to the cement.

Published: May 2017

The LaSalle Causeway lift bridge is a 100 year old highway bridge that is integral to the transportation network of Kingston, Ontario, Canada. Rehabilitation of the bridge was planned to address corrosion of the bottom chord and a gap identified at the support of the lifting end. To determine the effectiveness of this rehabilitation, the displacements of the bridge were monitored before and after the rehabilitation, during a static load test, and under regular traffic loading. Since the bridge crosses the Cataraqui River, there are no stationary reference points near midspan from which to measure displacement using conventional sensors. For this reason, digital image correlation was selected as an appropriate monitoring technology. Displacements at the midspan and supports of the bridge were recorded and used to assess the performance of the bridge. The results of this research indicate that the bridge complies with displacement limits and that the rehabilitation of the bridge was successful in rehabilitating the support conditions of the bridge.

Published: May 2017

Natural resource shortages and environmental issues have advanced the applications of industrial waste in road construction. Steel slag is a typical industrial waste. Its use in asphalt pavement is a hot topic. The lack of a production technique for high-quality steel slag aggregate has limited the wide use of steel slag in asphalt pavement in China. The primary objective of this research is to establish an advanced technique for steel slag coarse aggregate production. A modified production process consisting of a combined crushing, screening and cleaning technique is proposed. The quality of the steel slag coarse aggregate produced by the modified method and the performance of the asphalt mixture containing this steel slag coarse aggregate have been examined. The results show that the proposed production method significantly enhances the angularity and size specification stability of steel slag coarse aggregate. Asphalt mixtures with steel slag coarse aggregate shows satisfactory crack resistance and high-temperature deformation resistance.

Published: May 2017

Diabetic kidney disease is among the most frequent complications of diabetes, with approximately 50% of patients with ESRD attributed to diabetes in developed countries. Although intensive glycemic management has been shown to delay the onset and progression of increased urinary albumin excretion and reduced GFR in patients with diabetes, conservative dose selection and adjustment of antihyperglycemic medications are necessary to balance glycemic control with safety. A growing body of literature is providing valuable insight into the cardiovascular and renal safety and efficacy of newer antihyperglycemic medications in the dipeptidyl peptidase-4 inhibitor, glucagon-like peptide-1 receptor agonist, and sodium-glucose cotransporter 2 inhibitor classes of medications. Ongoing studies will continue to inform future use of these agents in patients with diabetic kidney disease.

Published: May 2017

The main objective of this paper is to analyse the structural changes in direction of India’s exports under the New Trade Policy since 1991. The period of study is 1987-88 to 2014-15. The paper uses the dominance pattern, ranking technique, mobility and turnover, concentration ratio and growth rate technique as research methodology for analysis. The results show that USA, UAE, Hong Kong, UK and Germany accounted for more than 62 percent of exports from India at the world level. UAE and Hong Kong are Asian Countries in top five and accounted for around 24 percent of India’s export. World concentration ratio of exports from India is negative, declining and low. In case of developing countries, UAE has emerged as the most important trading partner followed by Hong Kong, Singapore, Saudi Arabia and Bangladesh and accounted for more than 64 percent of India’s export to developing countries. Bangladesh is the only SAARC country in top five developing countries, while China and Russia of BRICS countries are in top list of India’s exports. India’s direction of foreign trade has exhibited a structural shift during the last two decades. Trade volume and trade share of emerging and developing economies has increased while the share of conventional trading partners (developed countries) has showed a declining trend.
The Metaphor of Consumerism
Authors: Hasyim Muhammad
Published: May 2017

This research uses semiotic of metaphor to unmask the underlying meaning beneath the semiotic of consumerism on television advertisements. This research attempts to explain how advertised products are being used, through the means of semiotic of metaphor by scrutinizing the dynamic relationship between sign and signifier. Semiotic of metaphor makes the products ‘alive’ within human society hence, this implies that the very existence of human beings is no longer determined by the presence of another human being, instead the very existence is now determined by the presence of certain commercial products in possession. The society, in term of consumerism, views the products as animate or living entities within the sphere of living. Commercial advertisements use metaphorical expressions to relate and exchange in two major concepts: products are humans, and humans are products’ users. Thus, nowadays, humans tend to seek their purpose of living and existence through consumerism. The result of this research shows that television commercial advertisements mainly work by means of certain metaphorical symbolism: it shapes society’s perspective into believing that the very existence of human beings, the actualization of self, and differentiations among them are achieved by using or purchasing certain advertised products therefore, the products serve as the symbols of those achievements.
Exploring Changes in Teachers’ Instructional Practice through Self-evaluation as a Meditational Activity: A Case Study
Authors: Tursini Umi
Published: May 2017

This study investigated an Indonesian English language teacher’s instructional practice and the extent to which the practice capable of change as a result of engagement in mediated self-evaluation. The study was framed using Vygotsky’s sociocultural theories. A case study, which drew on multiple data sources including interviews, classroom observations, and documentation, was employed. A range of artefacts including lesson video recording, student feedback, and collegial dialogue are used to self-evaluate teacher’s instructional practice. The qualitative analysis suggested that self-evaluation involving teacher's self-reflection on teaching in Indonesian university contexts had significant potential for mediating changes in instructional practice. The findings also revealed that teacher self-evaluation led to heightened self-reflection through which teachers understood themselves and their instructional practice more deeply in terms of their strengths and areas for development. This suggests that teacher self-evaluation contributes to professional learning by empowering teachers to transform their practice. Given that teacher self-evaluation is still a relatively new phenomenon in the Indonesian educational context; the positive outcomes reported in this study are promising. Hence, it is reasonable to recommend that educational leaders in Indonesia provide opportunities for teachers to formally self-evaluate. The necessary provisions must therefore be in place and will ideally include formal training or workshops on how to perform a self-evaluation, the allocation of time to carry out the process, and ongoing support to address teachers’ needs and concerns about the process in terms of consistency and timeliness.

Authors: Khoshsima Hooshang , Shokri Hadi
Published: May 2017

There has always been tremendous studies regarding teachers’ perception of using a definite approach in boosting speaking ability of EFL learners; however, fewer studies have stressed the essentiality of student engagement through Harmer’s ESA elements involved in enhancing speaking performance of EFL learners. The aim of the present study is to put an effort into investigating teachers’ perception of teaching-learning techniques through the utilization of three engage, study and activates (ESA) elements involved in teaching of tasks in mastering Iranian intermediate EFL learners’ speaking skills. Based on this notion, a number of 10 EFL experienced teachers were enrolled in conduction of the study. In order to analyze teachers’ apprehension of ESA elements, a questionnaire which contained a five- point 37 Likert-type close-ended items was utilized. The results of the teachers’ questionnaire revealed that most of the teachers hold a positive perception of implementing ESA elements in their classroom settings as an instructional approach in boosting speaking ability of EFL learners. In conclusion, findings of the study approve implementation of ESA in classroom setting. It is expected that the implications of the study may significantly contribute to the work of EFL teachers, EFL learners, syllabus designers, supervisors, material producers, textbook writers and researchers.
A Pragmatic Analysis of Vague Language in the News Articles on the Iraqi Security Crisis
Authors: Khalil Huda H.
Published: May 2017

There is a well-known belief among linguists and discourse analysts saying that vague language is one of the common features of political language. In order for the linguists to include vague language within the domain of linguistic analysis, they started formulating vagueness within the principles of the pragmalinguistic theory.  However, the pragmatic perspective had not been paid much attention yet. With the accelerated events in the Middle East, the best way to get information is to appreciate some news items because they are objective facts that are accessible and easy to comprehend for everybody (Pan, 2012, p. 2530). Iraq has witnessed many periods of serious escalation among which is the one started in April 2014 in which, the ISIS influence started expanding suddenly and rapidly causing infrastructure damage and causalities. The present paper aims at investigating vague expressions in news articles on the security situation in Iraq in the period mentioned above by means of Grice’s cooperative principle to find out the purposes vague language serves and its effects on these news articles.

Published: May 2017

Production of a clear-cut and comprehensive framework for the sake of evaluation purposes has been one of the most challenging issues in the realm of language assessment. Over the past decades, notable effort has been made to put forward models to practically define and theoretically specify the construct of language proficiency. To accomplish this, theorists have drawn on different epistemological sources such as empirical research, narrative accounts as well as introspective and retrospective analysis of language related data. The objective of this review is to conduct a critical analysis of the validity and practicality of these models and also to indicate the contributions as well as the drawbacks of these models from different standpoints. The analysis has been done in conformity with the widely accepted paradigms of socio-cultural and communicative orientations toward language within the field of language assessment.
