Academic Discourse in English Medium Instruction Contexts: A Look at Teacher Explanations
Authors: Martín-Del-Pozo María Ángeles
Published: January 2018

Teaching and learning content subjects through English requires a competence in academic language which Cummins (1984) labeled CALP (Cognitive Academic Language Proficiency). Revisiting this concept could shed light on the academic language skills necessary for communication in bilingual classrooms. A first step in this long journey could be a deeper comprehension of the academic linguistic or cognitive discourse functions (Dalton-Puffer, 2013). This paper approaches the function of explaining.

To accomplish this aim, six lecturers teaching through English at Escuela de Ingeniería de Informática (Segovia, Spain) were videotaped. Lessons were transcribed to create a corpus. The main research questions followed Dalton-Puffer´s (2007) model for a secondary education context:

1. How many occurrences of the academic function of explanation are there in the corpus?

2. What is the linguistic form of these explanations?

3. Is there any signaling language or metalanguage around them?

The seventy explanation fragments found were classified in three categories following Brown´s taxonomy (2006).

• Interpretative explanations respond to the question ‘What?’ and are very close to definitions.

• Descriptive explanations respond to the question ‘How?’ and centre on processes, structures and procedure.

• Reason giving explanations respond to the question ‘Why?’ and provide reasons and causes.

The findings show a rich frequency of this academic function in contrast to the very limited comparable previous studies in bilingual classrooms (Dalton-Puffer, 2007). Bar graphs of frequencies and distribution of types per lecturer are presented. Regarding qualitative aspects, the samples found offer insights about how explaining is performed in bilingual content lectures. The form of these explanations and the metalanguage signaling them are analyzed and illustrated with numerous examples from the corpus.

Taking as starting point the description of the explanations present in lecturer discourse some reflections about their potential for the learning of content and language are provided. The conclusions section suggests some pedagogical implications for the linguistic education of both students and lecturers in English medium instruction environments.
Strategies for Teaching Unbiased Language in English for Law Enforcement
Authors: Torregrosa Gabriela , Sánchez-Reyes Sonsoles
Published: January 2018

The EU Charter of Fundamental Rights (2000) forbids discrimination, and national legislations follow suit. Language is a symptom of and a contributor to an unequal status. Civil servants, and the police to a higher extent, must observe this in order to prevent secondary victimisation and contribute to attitudes of inclusion and equal opportunities. Therefore, training in non-discriminatory language is a must in any EFL course for law enforcers.

Different teaching methodologies are applied with trainee police officers (CEFR B1) in the Spanish Police Academy to obtain critical language awareness. These strategies allow trainee officers to produce discourse sensitive to difference, and have beneficial results in building up their linguistic proficiency addressed to their professional performance.
Needs analysis and competence profiling through ethnographic methods: the case of the Academic English course at the Graduate School of a Spanish university
Authors: Guillen Galve Ignacio
Published: January 2018

This paper reports findings from a micro-ethnographic study of the academic literacy practices of the doctoral students that participate in the course in Academic English (AE) taught at the Graduate School of the University of Zaragoza (UZ), Spain. So far there is no evidence regarding the degree of competence in spoken and written communication in academic English to be expected from the students that enroll in the course. Accordingly, the UZ has funded a Teaching Innovation Project (TIP) with the aim of developing ethnographic study protocols capable of providing empirical data on competence profiles, and analysing the learning needs of a specific type of EFL adult learner. The aim of this paper is, therefore, to report on those results that can help to improve the AE course by planning it more efficiently on the basis of a needs analysis that takes disciplinary factors, among others, into account. Reading specialized bibliography, writing a dissertation, giving an oral presentation... all seem to constitute manifestations of, or generic competences for, Academic English in tertiary education, but the acquisition of those competences in an EFL environment may become a challenge for the young researcher attending the AE course. Nowadays, effective teaching in that context requires going beyond mere experience and gathering empirical, ethnographic information suitable for competence profiling (see e.g. Bocanegra-Valle, 2016). Consequently, our study draws on relevant ethnographic techniques in the field of EAP (see e.g. Dressen-Hamouda, 2012), the paper thus beginning by reporting on the results of the analysis of the answers to a structured questionnaire administered to students as the starting point for small-scale semi- structured interviews. Our ultimate aim is the examination of the acquisition and learning of second-language academic literacy practices in line with e.g. 'New Literacies' studies such as Seloni (2012).
Soret and radiation effects on MHD chemically reactive Nano fluid flow over an exponentially accelerated vertical plate with ramped wall temperature and ramped surface concentration through porous medium
Authors: Mittal Akhil , Kataria Haribhai
Published: January 2018

Present paper is concerned with the study of flow, heat and mass transfer characteristics in the unsteady natural convective magneto hydrodynamics flow of chemically reactive electrically conducting Nano fluid past over an exponentially accelerated vertical plate in the presence of soret and thermal radiation. It is assumed that the bounding plate has ramped temperature with ramped surface concentration and isothermal temperature with ramped surface concentration profile through uniform porous medium. The governing non- dimensional partial differential equations are solved analytically using Laplace transform technique. The features of the fluid flow, heat and mass transfer are analyzed for all parameters by plotting graphs. Skin friction, Nusselt number and Sherwood number are obtained and represented through tabular form
Exploring EMI lecturers’ attitudes and needs
Authors: Banks Matthew
Published: January 2018

This paper focuses on English-medium instruction (EMI) at a Spanish public university. It reports on a mix-methods study into the attitudes and linguistic and pedagogical needs of EMI lecturers. First and foremost, the study has a practical focus and assesses lecturers’ needs and attitudes as the basis for developing an EMI training course. The study takes a “bottom-up” approach to needs assessment in order to guarantee a course that is fit for purpose. It collects data from university lecturers using multiple sources to provide empirical evidence with which to inform course design decisions. Data sources include a questionnaire, field notes from observations of EMI teaching practice, collaborative planning tutorials, lesson plans and lecturers’ reflections on EMI. The analysis of lecturers’ language use and pedagogical strategies suggests a number of areas for improvement that could enhance EMI teaching and learning. On the whole, the findings show a positive attitude towards EMI and training, but also highlight key tensions regarding attitudes towards more collaborative, learner-centred lecturing practices. It thus argues for careful consideration to be given to lecturers’ attitudes in the design of EMI teacher development courses.

Published: January 2018

The runtime verification community is still fragmented with non-interoperable specifications and tools. Within the EU H2020 project COEMS “Continuous Observation of Embedded Multicore Systems”, we are contributing to the European Open Research Data Pilot that makes scientific data available to other researchers. We describe our first contributions and experience with the required data management and discuss technical issues such as metadata management, format and storage on practical examples. Based on our experience, we make suggestions on tools and formats for future RV Competitions and for desired artefacts from the EU COST Action IC1402 "ARVI -- Runtime Verification Beyond Monitoring".
Connecting Learner Needs with Academic Discourse: a Research on LSP Courses at Beginners’ Level for Students of Art History and Archaeology in German Universities
Authors: Gay Debora
Published: January 2018

The paper introduces the relevance of the Italian language in the discourses of Art History and Archaeology and its properties. Then it focuses on the Learner Needs (LN) of a specific target audience: students of Art History and Archaeology, under- and postgraduates aiming to achieve LSP competence in Italian already as beginners or quasi-beginners. Being these general LN, how far is it possible to satisfy them with an LSP course on discourse relevant aspects in the academy? – The paper gives an answer to this question discussing some outcomes of a PhD research: in this doing, it describes the course design, learners’ profiles and their performances. Finally it suggests a flexible course concept with a main focus on didactics and on refined specific LN.
Going Polymorphic - TH1 Reasoning for Leo-III
Authors: Steen Alexander , Wisniewski Max , Benzmüller Christoph
Published: January 2018

While interactive proof assistants for higher-order logic (HOL) commonly admit reasoning within rich type systems, current theorem provers for HOL are mainly based on simply typed lambda-calculi and therefore do not allow such flexibility. In this paper, we present modifications to the higher-order automated theorem prover Leo-III for turning it into a reasoning system for rank-1 polymorphic HOL.

To that end, a polymorphic version of HOL and a suitable paramodulation-based calculus are sketched. The implementation is evaluated using a set of polymorphic TPTP THF problems.

Authors: Narsingani Fenny , Prajapati Mahendra B , Bhathawala Pravin Himmatlal
Published: January 2018

Public health is constantly under risk due to growing microorganisms. Infectious disease spread rapidly among the population in contact and so people take the different steps to reduce the transmission of disease. Compartmental model such as SIR model developed by W. Kermack and G Mckendrick are modeled for the progress of epidemic. Fixed point analysis has been applied to mathematical models of compartmental infectious disease models for understanding the long term outcome of disease. We have applied the analysis to the spread of infectious disease and obtained the threshold value and this threshold value helps us to predict when epidemic peaks.
On the Evaluation and Comparison of Runtime Verification Tools for Hardware and Cyber-Physical Systems
Authors: Rozier Kristin Yvonne
Published: January 2018

The need for runtime verification (RV), and tools that enable RV in practice, is widely recognized. Systems that need to operate autonomously necessitate on-board RV technolo- gies, from Mars rovers that need to sustain operation despite delayed communication from operators on Earth, to Unmanned Aerial Systems (UAS) that must fly without a human on-board, to robots operating in dynamic or hazardous environments that must take care to preserve both themselves and their surroundings. Enabling all forms of autonomy, from tele-operation to automated control to decision-making to learning, requires some ability for the autonomous system to reason about itself. The broader class of safety-critical systems require means of runtime self-checking to ensure their critical functions have not degraded during use.

Runtime verification addresses a vital need for self-referential reasoning and system health management, but there is not currently a generalized approach that answers the lower-level questions. What are the inputs to RV? What are the outputs? What level(s) of the system do we need RV tools to verify, from bits and sensor signals to high-level architectures, and at what temporal frequency? How do we know our runtime verdicts are correct? How do the answers to these questions change for software, hardware, or cyber-physical systems (CPS)? How do we benchmark RV tools to assess their (comparative) suitability for particular platforms? The goal of this position paper is to fuel the discussion of ways to improve how we evaluate and compare tools for runtime verification, particularly for cyber-physical systems.

Inference of fault signatures of discrete-event systems from event logs
Authors: Christopher Cody , Pencolé Yannick , Grastien Alban
Published: January 2018

In this paper, we propose a method to diagnose faults in a discrete event system that only relies on past observed logs and not on any behavioural model of the system. Given a set of tagged logs produced by the system, the first objective is to extract from them a set of fault signatures. These fault signatures are represented with a set of critical observations that are the support of the diagnosis method. We first propose a method to compute the fault signatures from an initial log journal and follow with detail on how the signatures can then be updated when new logs are available.
Cut-offs and Gestures: Analytical Tools to Understand a Second Language Speaker
Authors: Lopez-Ozieblo Renia
Published: January 2018

This paper will focus on one specific type of disfluency (speech less than fluent), that is, interruptions or cut-offs. The research on cut-offs has led to various hypotheses explaining how cut-offs are processed: Seyfeddinipur, Kita & Indefrey (2008) suggested that the cut-off is a controlled action and so on detecting the trouble the stop might be postponed, if necessary, to allow time for the resumption process; Tydgat, Stevens, Hartsuiker and Pickering (2011) added that the stopping and resumption processes are likely to occur concurrently and share the same resources. Therefore, the speaker has to decide whether it is more effective to stop and, if so, where.

In Second Language Acquisition (SLA) error has been the topic of much discussion. However, disfluencies have surprisingly aroused less interest. SLA usually takes the view that any repair following a disfluency is the consequence of linguistic difficulties (usually grammar or vocabulary). However, like among native speakers, there are more reasons for disfluency and repair than just linguistic difficulties.

A tool to aid disfluency analysis is that of the gesture performed together with speech. McNeill’s gesture theory holds that gesture and speech are two modalities of the same communicative process and that as such should be analysed together (2012). Therefore, the gesture might provide additional analytical information to the observer.

The objective of this study was to investigate the nature of cut-offs in speakers using their mother tongue and also a second language. As our specific interest is the acquisition of Spanish by English speakers, our results are based on data from 8 participants, 4 Spanish native speakers and 4 Hong Kong students of Spanish as a foreign language (L2). Our results, based on a combination of qualitative and quantitative analysis, indicate that cut-offs, and the gestures associated with them, are used similarly by native speakers of both English and Spanish, including the relationship between the cut-off and the repair or its absence and the gesture. However, the L2 results are very different, showing a significant increase of within-word cut-offs in Hong Kong participants and a decrease among Spanish native speakers. We observed differences in the length and number of pauses after the cut-offs, as well as differences as to the point at which the cut-off occurred in the word. This paper will provide explanations as to the differences observed as well as providing evidence to support some of the existing hypotheses on cut-off production and gesture-speech relationships.
Intermittent Fault Diagnosis as Discrete Signal Estimation: Trackability analysis
Authors: Pucel Xavier , Roussel Stéphanie
Published: January 2018

We address the problem of intermittent fault diagnosis as an instance of discrete signal estimation, in the context of fault management in autonomous systems and vehicles. We propose an estimation approach based on constrained optimization using conditional preference theories. We show that in some cases, our estimator can fail to find an estimation for the system. We provide a way to detect and eliminate these cases at design time.

And at the end we shows evaluation table which mention comparison of our scanner with two other web scanner tool. So finally this paper additionally shows how easy it is to scan web application bugs with dynamic analysis and retrieve hidden web pages from web applications.
The Interpretation of Negated Quantifiers in Spanish
Authors: Barberán-Recalde Tania
Published: January 2018

Children tend to accept weak Quantifiers (Q) in contexts where strong ones hold, failing to generate Scalar Implicatures (SI) (Noveck, 2001/2004). The interpretation of a negated sentence containing a Q requires: (i) pragmatic knowledge to derive the SI and (ii) syntactic knowledge to determine the scope of negation (Neg). Uttering any of the sentences in 1(a,b) in a context where zero students attended the talk is under-informative, because the stronger Q none should be employed in order to be as informative as possible (Grice, 1975/1989).

(1) a. NOT ALL the students attended the talk

b. ALL the students did NOT attend the talk

The fact that Neg occupies a different position in (1a) with respect to (1b) can have an influence on the interpretation of the sentence. While (1a) in English is interpreted by adults as ‘NOT ALL’=some, (1b) can be interpreted as ‘ALL NOT’=some or ‘ALL NOT’=none. Following the “Observation of isomorphism” (Musolino, 1998), children tend to obtain isomorphic-readings, so they are predicted to interpret ‘NOT ALL’=some and ‘ALL NOT’=none. Based on Katsos et al.’s (2012) materials, a Picture Selection Task (PST) was conducted with 5-year-old monolingual-L1Spanish (n=25) children, as well as with adult native speakers of Spanish (n=17), to test their interpretation of ‘all not’ for Spanish todos no (Q-Neg) and of ‘not all’ for no todos (Neg-Q). Participants had to select one of two pictures presented on a screen, after hearing an utterance containing Q-Neg or Neg-Q. The pictures represented a none-context (where zero of five items were in the boxes) and a some-context (where two of five items were in the boxes). Results from the PST showed that Spanish children chose the none-context for Q-Neg in 73% of cases (isomorphic-readings). For Neg-Q the results were not so homogeneous, since Spanish children chose the some-context in 55% of cases. Spanish adults chose the some-context for Neg-Q in 95% of cases, and for Q-Neg the none-context in 83% of cases. While Spanish children and adults prefer the none-reading in Q-Neg, adults’ preference for the some-reading in Neg-Q contrasts with children’s response in that condition. This response pattern raises new questions regarding children’s preference for isomorphic-readings and leads to interesting predictions for the acquisition of negated Qs in Spanish.

Penambahan gugus penarik elektron menurunkan IE% hingga mencapai 82,82 %. Kajian teoritis ini akan berkontribusi besar dalam mendesain dan sintesis senyawa inhibitor organik dengan efisiensi inhibitor tinggi.Kata kunci: inhibitor korosi, teori fungsional kerapatan, thiaamida-pirazolindolAbstract. Corrosion inhibitor properties of thiamide pyrazolindole and its derivatives has been elucidated by means of density functional theory (DFT) at B3LYP/6-31G(d) level of theory. Effect of electron donating and withdrawing groups such as NH2, SH, CHCH2, CH3, OH, CHO, COOH, F and NO2 on the corrosion inhibitor of thiamide pyrazolindole derivatives also have been studied. The quantum chemical parameters such as the frontier orbital energies (EHOMO), ionization potential (I), electron affinity (A) and electronegativity (Ãâ¡) are closely related to the corrosion inhibition efficiency (IE%) of thiamide pyrazolindole derivatives. The presence of electron donating groups increases IE% values meanwhile electron withdrawing groups reduce IE% values. The enhancement of IE% follows NO2 < CHO < COOH < SH < F < CH3 < CHCH2 < OH < NH2. Electron donating NH2 group gives 98,76 % of IE%, pure thiamide pyrazolindol IE% = 90,80 %. In contrast, electron withdrawing NO2 group gives IE% only 82,82 %. This theoretical study would have a significant contribution in designing high-efficiency organic corrosion inhibitors.Keywords: corrosion inhibitors, density functional theory, thiamide pyrazolindol

Introduction: Distal femoral fractures comprise 4-6% of all femur fractures. The management of distal femur fractures are challenging because of significant morbidity and complication rate even with advanced surgical techniques and implants. Open reduction and internal fixation (ORIF) with pre-contoured distal femoral locking compression plate (DF-LCP) is one of the most acceptable surgical procedures these days.Objectiv: Evaluation of functional outcomes of distal femur fractures managed surgically using DF-LCP at Koshi Zonal Hospital.Methodology: In this cross sectional study 21 patients having closed distal femur fractures with or without intra-articular extension to femoral condyle fixed with DF-LCP at Koshi Zonal Hospital, Nepal from March 2016 to March 2017 were included. Patients with open fracture, severe comminuted fracture, and neurovascular impairment were excluded. These patients were followed-up for up to one year and we recorded the knee range of motion, full weight bearing time fracture union time, and complications. We used Neers' functional scoring system to evaluate the final outcomes and data was analysed using Microsoft Excel Programe.Results: Out of the 21 patients of distal femur fractures, 16 were diametaphyseal distal femur fractures and five were supracondylar fractures with intra-articular extension. Mean age recorded was 45 (range 19-75) years, hospital stay mean duration 12 (range 10-19) days and duration of surgery 85 (range 60-150) minutes, full weight bearing walking time mean 16 (range 12-22) weeks, radiological union time mean 20 (range 17-29) weeks and Neers' score was excellent in 66.66%, satisfactory in 23.80%, unsatisfactory in 4.76%, and poor in 4.76%.None of our patients had complications like; loss of fixation, implant failure or post-operative neurovascular injury.Conclusion: Distal Femoral Locking Plate is one of the best implant to be used as fixation method for both extra-articular and intraarticular distal femur fracture.Birat Journal of Health SciencesVol.2/No.3/Issue 4/Sep- Dec 2017, Page: 260-265
Cesarean Scar Pregnancy - A Rare Entity: Two Case reports
Authors: Mahato Krishna , Bin Yu
Published: January 2018

Cesarean scar pregnancy is the implantation of an embryo within the mymometrium of prior cesarean scar which is a rare variant of ectopic pregnancy. Such implantation is life threatening leading to uterine rupture, extensive hemorrhage and serious maternal morbidity. Making an early diagnosis minimizes risk of such major hemorrhage thus preserving the uterus and further fertility. In this case report we discuss two different management options: ultrasound guided intragestational methotrexate injection with sac aspiration; and transvaginal hysterotomy considering the severity of presenting symptoms. Birat Journal of Health SciencesVol.2/No.3/Issue 4/Sep- Dec 2017, Page: 312-315
