Homotopy perturbation method with an auxiliary parameter for nonlinear oscillators
Authors: Yu Dan-Ni , He Ji-Huan , Garcıa Andres G
Published: November 2018

A brief introduction to the development of the homotopy perturbation method is given, and the main milestones are elucidated with more than 90 references. This paper further improves the method by constructing a homotopy equation with one or more auxiliary parameters embedding in the linear term with a clear advantage in accelerating and controlling the approximation convergence speed. Moreover, a revision of a recent amplitude-period approximation formula is presented providing an answer to an open problem related to the optimal approximation along with a new universal formula. Duffing equation is used as an example to illustrate the solution process for the homotopy perturbation method, and only one or few iterations are needed in practical applications, making the method much attractive. From the side of amplitude-period formulation, the nonlinear pendulum, the Duffing equation and an oscillator with discontinuity are analyzed providing an asymptotic exact equivalence for bigger parameter values in the case of Duffing’s system. This mini review gives a tutorial guideline for practical applications of the homotopy perturbation method, the references are not exhaustive.
Developing facilitation skills amongst undergraduate nursing students to promote dementia awareness with children in a higher education institution (innovative practice)
Authors: Gibson Caroline , Rennie Karen , Dewing Jan , McKinlay Lesley
Published: November 2018

Final year students on a BSc Hons Nursing programme in Scotland were supported to become Dementia Friends facilitators and develop interactive dementia awareness sessions for children from local schools. The children were invited to indicate phrases and images they associated with ‘dementia’ at the outset and end of the session. Analysis of the responses suggested that there were positive changes in the children’s values and beliefs when thinking about a person living with dementia during the sessions. We suggest that peer learning is a valuable strategy to increase public and professional awareness about dementia and supports the development of graduate attributes.
Effects of the angle of impact on the aeroacoustic feedback mechanism in supersonic impinging planar jets
Authors: Gojon Romain , Bogey Christophe
Published: November 2018

Three planar impinging supersonic jets of infinite extent are simulated using compressible large eddy simulations in order to study the effects of the angle of impact on the flow and acoustic fields of the jet. At the exit of a nozzle of height h, they are ideally expanded and have an exit velocity uj, yielding a Mach number of 1.28 and a Reynolds number of 5 × 104. They impinge on a flat plate at a distance 5.5 h from the nozzle lips with angles of 60°, 75°, and 90° between the jet direction and the plate. Mean velocity flows and snapshots of density, pressure, and vorticity are first shown. The mean convection velocity of the turbulent structures in the jet shear layers is then determined. The sound pressure levels are computed, and several tones due to the presence of a feedback mechanism are found to establish between the nozzle lips and the flat plate. They agree well with the corresponding measurements and with the classical model of the feedback mechanism. Moreover, when the angle of impact deviates from 90° to 75°, a jump from the third to the fourth mode of the feedback mechanism and a reduction in intensity are noted. By applying a Fourier decomposition to the near pressure fields, hydrodynamic–acoustic standing waves are found for each dominant tone frequency. Moreover, as suggested by amplitude fields and velocity spectra in the jet shear layers, the feedback mechanism seems to establish mainly along the lip that is farther away from the plate when the impact angle is not normal. This jump from the third to the fourth mode is similar to the jump observed experimentally for an angle of impact of 90° when the nozzle-to-plate distance increases from 5.5 h to 5.85 h. Finally, for an angle of impact of 60°, it is seen that none of the modes of the feedback persists in time, but that several modes randomly establish during short periods of time. These rapid switches between different modes lead to several tones that are less energetic on average and centered on St = 0.25.
Second-generation youth in Italy and their path to adulthood. Who is supporting them?
Authors: Dusi Paola , González-Falcón Inmaculada
Published: November 2018

In Italy, 9.2% of school students come from a migrant family. Of these, 55.3% were born in Italy itself. With the data revealing a situation in which these young, second-generation migrants face educational disadvantages that lead to structural inequality and social injustice, we ask: which adults are supporting them during their education? We present results from a qualitative study that, to date, has involved 25 young adults from migrant families. The data highlight the importance of primary and secondary agents of socialisation, though they more clearly decry the isolation that ‘differentness’ brings. The institutional context (schools, job market, welfare/citizenship policies) generates unintentional segregation that leads to social exclusion. In Italy, two issues come to the fore: (a) the inadequacies of the school system (curriculum, teacher training, support of L2 acquisition) and (b) citizenship laws that penalise second-generation migrants.
Using the trajectory of the shuttlecock as a measure of performance accuracy in the badminton short serve
Authors: Vial Shayne , Cochrane Jodie , J. Blazevich Anthony , L. Croft James
Published: November 2018

Accuracy of a projectile is typically quantified as the proportion of successful target hits, or the distance an object finishes from the target. Serving in sports such as badminton differs since the shuttlecock is usually intercepted by the opponent before landing on the target (i.e. court surface). Therefore, landing accuracy measures are inappropriate and a new method of determining accuracy of the serve is needed. During interviews, elite coaches and players described an accurate short serve as crossing the net with low clearance and having an apex before the net. Three-dimensional trajectory of the shuttlecock was therefore tracked from eight national-level players who performed 30 short serves in simulated match conditions (i.e. with an opponent); 27% of all serves were classified as ‘accurate’, 27% of serves as ‘inaccurate’, 21% with a ‘good apex’ position, and 25% with a ‘good clearance’ height. The proposed method of assessing shuttlecock trajectory as a measure of accuracy could be adopted by coaches and players to assess and improve short serve accuracy. Furthermore, this method is more representative of a match environment since the shuttlecock rarely lands because the opponent returns the serve.
Decolonizing curriculum: Student resistances to anti-oppressive pedagogy
Authors: Zinga Dawn , Styres Sandra
Published: November 2018

Drawing from multiple courses, the authors explore the intersections and connections concerning the various ways students in mainstream programmes experience and express counter-resistances to decolonizing and anti-oppressive pedagogies. The authors focus on how aspects of curriculum can at once minimize, trigger and/or provoke various aspects of resistances. They also consider how the positionality of the instructor and purposeful and mindful choices in curriculum, course content and classroom practices assist students to reflect on their own positionality and the ways networks and relations of power and privilege are implicated in learning and teaching. From the perspectives of one Indigenous and one non-Indigenous instructor, the authors share practical examples related to decolonizing and anti-oppressive pedagogies within higher education contexts.
Mortality in people with coeliac disease: Long‐term follow‐up from a Scottish cohort
Authors: Quarpong Wilhemina , Card Timothy R , West Joe , Solaymani-Dodaran Masoud , Logan Richard FA , Grainge Matthew J
Published: November 2018

Background

Few studies have determined the very long‐term mortality risks in adult and childhood‐diagnosed coeliac disease.

Objective

We quantified mortality risks in coeliac disease and determined whether age at diagnosis, or time following diagnosis, modified these risks.

Methods

Standardised mortality ratios were determined using data from a cohort of 602 coeliac patients assembled between 1979–1983 from Lothian, Scotland, and followed up from 1970–2016.

Results

All‐cause mortality was 43% higher than in the general population. Excess deaths were primarily from haematological malignancies (standardised mortality ratio, 4.77) and external causes (standardised mortality ratio, 2.62) in adult and childhood‐diagnosed cases respectively. Mortality risks declined steadily with time in adult‐diagnosed cases (standardised mortality ratio, 4.85 in first year compared to 0.97, 25 years post‐diagnosis). Beyond 15 years, this group had a significantly reduced risk of any malignancy (standardised mortality ratio, 0.57 (95% confidence interval: 0.33–0.92)). In contrast, for childhood‐diagnosed cases an increased risk existed beyond 25 years (standardised mortality ratio, 2.24).

Conclusions

Adult‐diagnosed coeliac patients have a temporarily increased mortality risk mainly from malignant lymphomas and a decreased risk of any malignancy beyond 15 years post‐diagnosis. In contrast, childhood‐diagnosed cases are at an increased risk of mortality mainly from external causes, and have long‐term mortality risks that requires further investigation.
Animation and informative films: Two early ‘digital’ films
Authors: Ceccarelli Nicolò
Published: November 2018

During the 1960s two of the most influential teams of visual communicators of that time produced short information films on digital technology for some of the major competing companies in the field. Both La memoria del futuro (Risi 1960) (‘The memory of the future’), produced in 1960 for Olivetti by a team led by Italy’s graphic designer Giovanni Pintori and Academy Award nominated animator Giulio Gianini, and A Computer Glossary, produced eight years later for International Business Machines (IBM) by the celebrated Eames Office, took great advantage of the combined powers of graphics and animation to make the abstract workings of computer processing accessible. Either on its own, or combined with footage from the ‘real world’, animated sequences have proved to be a very effective way to make complex contents easier to grasp for a wide audience, enabling communicators and directors to create very articulated narrative structures. Such structures offer degrees of conceptual versatility unthinkable in the domain of realistic documentary. Through the comparison and analysis of the two short films Olivetti and one IBM, this article aims to discuss the elements that make the language of animation an ideal tool to make complex and abstract things more understandable, without losing its ability to engage and entertain its public, therefore opening the way for a very promising season of informative animation.
Defining animation therapy: The Good Hearts Model
Authors: Hani Melanie
Published: November 2018

This article discusses ‘the Good Hearts Model’ (GHM), a programme of therapeutic practice that employs the process of producing animated films and allied materials. Though ‘art therapy’ in all its guises and diversity has a long pedigree, I argue that the use of animation (the GHM) offers an additional approach to traditional therapeutic strategies, and that it can also be used as a diagnostic, educational, crime-prevention and dissemination tool. Crucially, this discussion argues and proposes that like art, drama and music therapy, there is a need for a professional body for animation therapists, and inclusion in the Health and Care Professions Council (HCPC). For this to transpire I will propose a definition of ‘animation therapy’, and provide examples of its use in various contexts. The article will begin with a brief overview of the current context for art therapy and its conduct, followed by an introduction to the current situation regarding animation therapy in the United Kingdom, identifying how animation therapy is distinct, before engaging with the GHM and its potential within the field as an alternative approach to traditional therapy. There are many other creative therapies but for the purposes of this article, I will only discuss animation in relation to art therapy and within the wider paradigms of therapeutic practice. It will be focused upon the United Kingdom and the development of animation as a regulated therapy, with a specific attention to the GHM. It is also impractical to discuss all the research projects that have been undertaken over the years as this model of animation therapy has evolved, and hence a selection has been made to relate to the most appropriate arguments.
The new needs friends: On the academic as a critic and a public voice
Authors: Wells Paul
Published: November 2018

This discussion is concerned with looking at the academic as a ‘critic’ in the service of becoming a public voice, and in conducting production-based work that is directed at social issues and public engagement. The analysis draws upon a variety of definitions of ‘criticism’ from both a scholarly and journalistic perspective, eventually developing two kinds of criticism – the auto-critique and the procedural-critique – that play out the relationship between ‘the creative’ and ‘the critic’, essentially defining a theory of practice, and the practice of theory. These theorizations are then illustrated through the projects described in the following essays, seeking to show that the academic practitioner/creative must necessarily cultivate a model of ‘critique’ that both self-consciously monitors process while creating a practice outcome that speak to research questions. This then becomes comparable to external critical agencies that engage in the analysis of process in order to articulate its critical context in the service of evaluating outcomes. The essay essentially explores the complex relationship between these two models and their place with regard to institutional, social and cultural roles.
When they go low, we go high: Scholars of color, activism, and educational research in a post-truth era
Authors: Childs Joshua , Johnson Sarah
Published: November 2018

In the post-truth era, research from scholars of color will serve greater utility due to their propensity to speak truth to power, counter inaccurate narratives about marginalized populations, and challenge the politics that emerge during the post-truth era. This paper will highlight how scholars of color have centered race and social justice within their research, and provide examples of how the educational research community should counter the current post-truth era.  We propose that scholars of color should be more prominent in our research agendas. This includes citing more of their work, supporting research agendas that positions ‘race’ at the center, and promoting critical scholarship that moves away from deficit language. If we are going to speak truth to power in today’s post-truth climate, then educational researchers must produce critical scholarship that challenges the lies and myths that permeate in a post-truth era.
Appropriated literacies: The paradox of critical literacies, policies, and methodologies in a post-truth era
Authors: Bacon Chris K.
Published: November 2018

Since 2016, there has been a proliferation of discourse around what has come to be called “post-truth.” Much of this discourse references critical literacies as a proposed means by which to disrupt post-truth across educational policy, pedagogy, and methodology. In this paper, I highlight the paradoxical degree of overlap between post-truth and the critical literacy approaches espoused to combat it. Left underexplored, these appropriated literacies may do more to embolden than to dismantle post-truth. I first typify three “first wave” responses to post-truth, exploring the affordances and limitations of each. I then provide recommendations for augmenting these responses through a renewed emphasis on power, domination, and liberation in critical literacies as a response to post-truth.
New genealogies and the courage of truth: Toward an ethics of adversarial public educational scholarship and policy activism
Authors: Burns James P. , Green Colin D. , Nolan Jaime
Published: November 2018

Science denial in the post-truth era is driven by both the rejection of empirical science and the fraudulent use of scientific language. Education policy based on junk science produced by philanthrocapitalists depoliticizes political questions by relocating complex legislative and policy issues from the realm of political and philosophical discourse to that of scientific rationality using metrics and methods that are themselves fatally flawed. Dominant configurations of institutional power also attack scholarship that both debunks spurious causal claims and establishes causal links to existential crises, which in both cases inconveniences the neoliberal capitalist project. We discuss the methodological implications of education research as the counter-conduct of policy advocacy against power claims based on both the rejection of empirical science and the production of junk science. We both discuss and model Foucault’s tactic of genealogy and his analysis of parrhēsia, or truth telling, through creating an imperfect, preliminary genealogy of the “new” post-truth era, which contextualizes contemporary technologies of alternative facts in the history of public relations and propaganda that extend to the early 20thcentury. The methodological and political tactic of genealogy could be a move toward a new ethics of adversarial public scholarship that seeks to reconfigure what counts as scholarship in academia, itself a rationalizing disciplinary institution. Considering the moment, the study of power, the academy’s roles both in subverting and perpetuating it, and the necessity of epistemological and methodological counter-conduct have perhaps never been more important.
Start Here, Or Here, No Here: Introductions to Rethinking Education Policy and Methodology in a Post-Truth Era
Authors: Wolgemuth Jennifer R. , Koro-Ljungberg Mirka , Marn Travis M. , Onwuegbuzie Anthony J. , Dougherty Shaun M.
Published: November 2018

This special issue takes up urgent questions about how we education scholars might think and do policy and methodology in what has come to be known as the post-truth era. The authors in this special issue grapple with questions about the roles and responsibilities of educational researchers in an era in which research and policy have lost their moorings in T/truth. Collectively they reconceptualize educational research and policy in light of post-truths, anti-science sentiment, and the global rise of right-wing populism. At the same time we editors wonder whether post-truth is given a bad rap. Could post-truth have something productive to offer? What does post-truth open up for educational research and policy? Or, is the real issue of this special issue a collective despair of our own insignificance and obsolescence in the wake of post-truth. Whatever we editors and authors aimed to do, this special issue will not be heard by post-truth adherents and partisans. Perhaps its only contribution is encouragement to stay with the troubles of a post-truth era, even as we despair the consequences of our research and policy creations.
Blended learning in large enrolment courses: Student perceptions across four different instructional models
Authors: Owston Ron , York Dennis N. , Malhotra Taru
Published: November 2018

Drawing on data from five large enrolment introductory courses in a public university, we compared students’ perceptions of blended learning on design, interaction, learning, and satisfaction in four different blended models. The models, which were the result of a course redesign initiative, had different combinations of face-to-face lectures, online sessions, and small group tutorial classes. Our findings suggest that students perceived courses with fully online lectures and in-class tutorials most positively on design and overall satisfaction, while those enrolled in courses with in-class lectures and in-class tutorials, supplemented by online discussions, felt most positively about interaction. Students perceived learning in the former courses more favourably than the latter, however the differences were not statistically significant. The least preferred model overall was the one that had in-class lectures and tutorials that alternated weekly between in-class and online sessions.
Die Quantifizierung von Nicht-Routine
Authors: Pfeiffer Sabine
Published: November 2018

In Prognosen zu Beschäftigungseffekten durch die Digitalisierung wird das Ersetzungsrisiko stark mit dem Anteil an Routinetätigkeiten verknüpft. Insbesondere maschinennahe Tätigkeiten gelten dabei als routiniert und daher als besonders bedroht. Auf Basis der BIBB/BAuA-Erwerbstätigenbefragung misst der AV-Index die Nicht-Routine-Anteile im Arbeitshandeln. Dabei zeigen auch maschinennahe Tätigkeiten hohe Anforderungen im Umgang mit Wandel, Komplexität und Unwägbarkeiten – und damit hohe Anteile an Nicht-Routine. Ziel des Beitrags ist die methodische Prüfung und Weiterentwicklung dieses Instruments mithilfe einer ökologischen Validierung. Dafür werden Primärerhebungen in einem Automobilwerk und einem Formenbau als Kontrastbetrieb vorgestellt. Die dort vorgenommenen qualitativen Analysen zu vier Produktionstätigkeiten werden erstens mit in den Unternehmen durchgeführten quantitativen Erhebungen des AV-Index verglichen und die Ergebnisse zweitens mit den Daten der BIBB/BAuA-Erwerbstätigenbefragung in Beziehung gesetzt. Diese Validierung des AV-Index bestätigt – zumindest für die untersuchten Produktionstätigkeiten – dessen Güte.
Geolinguistic complexity in Berber. Structural and algorithmic perspectives
Authors: Lafkioui Mena B.
Published: November 2018

The present article discusses how the combination of structural (qualitative) and algorithmic (quantitative) perspectives provides valuable insights into geolinguistic patterning and variability, and hence testifies to the importance of the integrating approach in addressing geolinguistic complexity. In doing so, it shows how language is constantly modulated in the form of innovations that emerge in structurally layered and causal formations, dictated by a subtle interplay between system-based and system-external properties. A case that accounts for this kind of geolinguistic complexity is provided by this data-driven study on Berber (Afro-asiatic), which shows how certain phonological and morphological innovation processes triggered by the vocalisation of the liquids /r/, /ṛ/, /rr/ and /ṛṛ/ in Rif Berber (North, Northeast, and Northwest Morocco) create language variation and change. Furthermore, the Berber data examined demonstrate the significant role of certain system-internal factors, such as economy and code conformity, in the diffusion of new phonetic, phonological, and morphological items. In order to better understand the intricacy of the various vocalisation phenomena addressed in the study, the results of the qualitative analysis (synchrony and diachrony) are also contrasted with the algorithmic results ensuing from computing geolinguistic distances by means of the Levenshtein distance calculating method with phone strings tokenised in pair-wise alignments (pondered variables).
A Comparative Study on Neural Network Based Controllers Used in Grid-Interactive Solar System
Authors: Patowary Moushumi , Panda Gayadhar , Deka Bimal C.
Published: November 2018

This paper proposes a comparative assessment of NN based current controllers followed by hardware validation towards power quality improvement in grid-interactive VSI controlled solar system. The steady state errors, transient disturbances and high current harmonic effects encountered in conventional linear PI and PR controllers are nullified by employing intelligent adaptive current controller. Three adaptive current control strategies viz. ADALINE-LMS, ALLMS, and VLAS-LMS are identified by using artificial neural network topology having been controlled by different weight-regulating algorithms which helps in minimizing current harmonics generated by the widespread use of VSI, non-linear loads, faults and uncertain polluted grid. A comprehensive comparative study is driven from the proposed adaptive controller's stability and convergence criterion, current magnitudes calculated at different power zones, % overshoot, settling time and power quality and analyzed under numerous operating conditions. From the comparative assessment performed in between conventional and intelligent current controllers, it is confirmed that the intelligent control technique performs best under the non-linear loads and transient conditions whereas all the controllers perform equally good under the linear loads. Proposed methods are simulated in MATLAB/Simulink and their effectiveness is compared in terms of time responses, stability and low-order current harmonics compensation capability. The robustness of the intelligent current controller is established through the experimental performances using dSPACE RTI 1202.
Analysis of Bifurcation and Chaos of the Size-dependent Micro–plate Considering Damage
Authors: Wang Xiumei , Yuan Jihai , Zhai Haorui
Published: November 2018

In this research, nonlinear dynamics and characteristics of a micro–plate system under electrostatic forces on both sides are studied. A novel model, which takes micro-scale effect and damage effect into account, is established on the basis of the Talreja’s tensor valued internal state damage model and modified couple stress theory. According to Hamilton principle, the dynamic governing equations of the size-dependent micro–plate are derived by variational method and solved via Galerkin method and the fourth order Runge-Kutta method. The effects of damage variable and material length scale parameter on bifurcation and chaos of the micro–plate system are presented with numerical simulations using the bifurcation diagram, Poincare map. Results provide a theoretical basis for the design of dynamic stability of electrically actuated micro- structures.
A Study on Torsional Vibration Suppression Method for an Integrated Helicopter / Engine System
Authors: Wang Yong , Zheng Qiangang , Zhang Haibo , Chen Mingyang
Published: November 2018

In order to solve the problem of torsional vibration instability of control unit in helicopter/engine system during maneuver flight, this paper has conducted the research on the integrated torsional vibration suppression of helicopter/engine system. Firstly, an integrated helicopter/engine model combined with torsional vibration is established based on the UH-60 helicopter model. Then the torsional vibration filter that is composed of a notch filter and a low-pass filter is applied to speed control loop of the engine to suppress the torsional vibration of power turbine speed. It is shown that the integrated helicopter/engine model combined with torsional vibration can simulate the torsional vibration characteristics under variable rotor speed, and both the low-order and high-order amplitudes of torsional vibration can be effectively eliminated below 0.04 % at constant rotor speed through utilizing the torsional vibration filter. Meanwhile, when the helicopter operates under variable rotor speed, the fundamental frequency of torsional vibration varies from 1.30 Hz to 2.30 Hz. However, all torsional vibration amplitudes within this frequency range can be damped less than 0.05 % through the notch filter whose bandwidth is 2.3 Hz, which proves the remarkable effect of torsional vibration suppression.

Todos los pacientes fueron tratados con el mismo tipo de metal trabecular. Resultados: Al promedio de seguimiento mencionado la supervivencia del componente acetabular fue del 97,6%. Un paciente fue tratado con artroplastia de resección debido a una infección persistente. La tasa de complicaciones totales fue del 12% y el promedio del Harris Hip Score posoperatorio fue de 81,54 (rango 63,25-92,75). Conclusiones: Aunque se necesita un seguimiento más prolongado, el uso de copas de metal trabecular logra resultados prometedores para el tratamiento de acetábulos complejos.
Prevalence rate of intimate partner violence by WHO region: an appraisal by current data
Authors: Jenabi Ensiyeh , Khazaei Salman
Published: November 2018

Intimate partner violence (IPV) is a major public health concern that annually affects 1 in 3 (35%) of women worldwide. The term “intimate partner violence” defines as physical, sexual, or psychological harm by a current or former partner or spouse.

Women with the characteristics like: low level of education, history of abuse among parents, history of childhood, abuse, antisocial personality disorder, attitudes accepting violence and male privilege are more susceptible to IPV. Consequence of this violence, victims may experience some serious short- and long-term physical, mental, sexual and reproductive health problems such as injuries, chronic pain, gastrointestinal, and gynecological problems including sexually-transmitted diseases, depression, homicide or suicide, and post-traumatic stress disorders.
A májátültetés aneszteziológiai-intenzív terápiás vonatkozásai
Authors: Fazakas János , Smudla Anikó
Published: November 2018

Abstract:

One of the most prominent results of our age is organ transplantation, the single treatment option for patients with end-stage organ failure. The success of transplants depends on the donor care, the patient preoperative preassessment, the perioperative care of organ transplantation and aftercare. Successful transplantation therefore requires a prominent level of continuous collaboration between the surgeon, anaesthesiologist, radiologist, internal medicine and hepatologist, laboratory physician and almost all their associates. The complex interdisciplinary approach based on the research results can be used to improve the patient’s condition through pharmacotherapy, physiotherapy and psychotherapy during the time spent on waiting lists. The emergence of more active, targeted therapeutic options in perioperative graft resuscitation may help the currently inferior quality transplantable grafts or resuscitation out (machine perfusion) or in the recipient, thereby increasing the number of liver transplants. Deeper knowledge of hemostatic processes, along with the development of surgical techniques, would increase the number of blood transplant free transplants, thus improving the long-term survival of grafts. The present study aims at presenting the anaesthesia and early intensive therapy aspects of liver transplantation from aptitude assessment, through anaesthesia to early intensive therapeutic treatment.

Abstract:

The mechanical circulatory support (MCS) program of the Semmelweis University Heart and Vascular Centre has become established over the last five years. The main requirements of our MCS program to be developed first were the Heart Transplantation and Heart Failure Intensive Care Unit and a well trained medical team. The wide range of mechanical circulatory support devices provides suitable background for the adequate treatment of our patients in all indications. In this review, we present our results related to extracorporeal membrane oxygenation (ECMO) supports performed in the last five years. Between 2012 and 2017, we applied MCS support in 140 cases, among them 111 patients received ECMO support. The leading indications of ECMO support were the following: primary graft failure after heart transplantation (33 cases), postcardiotomy cardiogenic shock (18 patients), acute decompensation of end-stage heart failure (14 patients), acute myocardial infarction complicated with refractory cardiogenic shock (37 patients), cardiogenic shock developed after transcatheter aortic valve implantation (3 patients), malignant arrhythmia due to drug intoxication (1 patient) and acute respiratory distress syndrome (4 cases). The mortality of patients receiving ECMO support was 46%. The analysis of the results of ECMO support needs to change our approach. The mortality results show that we lost the half of our patients. However, the mortality in the conventionally treated patients would have been 100% without ECMO. In fact, we could save the life of half of these patients. Orv Hetil. 2018; 159(46): 1876–1881.

Embracing Neapolitan as a Language Which Is Key to the Reconstruction of Early Romance
Authors: Ryan John M.
Published: November 2018

Despite being the second most spoken language on the Italian peninsula, Neapolitan has been overlooked in some of the more important comparative linguistic studies of the twentieth and twenty-first centuries. A survey of these studies suggests the preference for: 1) national languages, in this case, Italian, 2) languages that possess comparably the largest number of speakers, especially those that have swelled exponentially for reasons of immigration, as in the cases of Spanish, Portuguese and French; or 3) insular languages such as Sardinian which, despite its relatively low number of speakers, appears to have been included because of its sequestered history and the inevitability of differently evolved forms. The reason for this study is to demonstrate that because of exclusion among the ranks of other more elite languages, certain key structures of Neapolitan have been overlooked as potential exemplars of earlier forms of Romance. This paper suggests reasons for why the exclusion of Neapolitan in previous comparative language studies has only served to obscure the relevance of other factors that are key to the reconstruction of early Romance. The paper will also provide specific examples from the Neapolitan lexicon that serve to demonstrate how this variety conserves early forms of Romance.

Authors: Mahini Ramtin Noor-Tehrani (Noor) , Barth Erin , Morrow Jed
Published: November 2018

Being the only Vietnam War author on the English curriculum for American middle and high schools, Tim O’Brien skillfully mixes his real wartime experience with fiction in his various bestsellers and awarded novels.  All O'Brien's Vietnam War stories are always "bad," meaning that the war contains mostly sad and horrific experience for American soldiers and Vietnamese civilians. A closer look at O’Brien’s war stories reveals that he indeed touches upon almost all issues the American GIs encountered during this war; nevertheless, not all online literary analysis websites and peer-reviewed authors can identify or call them all out. To assist middle and high school readers in understanding the meaning behind Tim O’Brien’s Vietnam War stories, the war details in Going After Cacciato and its historical perspective are discussed in this article. The war-related issues that O’Brien touched upon in this novel are: lack of purpose, the lower standards of the American troops (McNamara’s morons), desertion, lack of courage, friendly fire, fragging their own officers, and contemptuous attitude toward the Vietnamese, the very people they came to help and protect.

This study explores Saudi EFL teachers’ needs and perceptions towards training programmes in Saudi Arabia. The data were collected using a semi-structured questionnaire from a total of 215 EFL teachers; 10 of these teachers were also interviewed. The main findings revealed that Saudi EFL teachers have a positive attitude and view that training programmes meet their various needs, such as a need for programmes on English teaching aids; assessment and grading strategies concerning learners’ language proficiency; and programmes concerning classroom practices that implement activities to support language acquisition and development. On the other hand, the teachers showed a need for training programmes on teaching English at the primary school level, plus for training programmes with qualified and professional trainers and educators. The study concludes with some implications and recommendations based on the findings.
Task-based Language Teaching in Southwest China: Insider Perspectives from Secondary School Teachers
Authors: Ye Xuejun
Published: November 2018

A voluminous body of research has examined the implementation of task-based language teaching (TBLT). However, research investigating the implementation of TBLT in Southwest China remains limited. This article reports on a study of teachers’ knowledge of TBLT, difficulties in deploying TBLT and their perceived feasible solutions. Thirteen teachers from a private junior secondary school in Sichuan, China participated in the semi-structured interviews. The findings reveal that teachers’ understanding of TBLT was limited and varied. The implementation gap was attributed to various contextual constraints such as exams, teachers’ beliefs, and pressures and challenges from the school. Participants of this study disseminated both similar and differentiated views towards problems and solutions. The study concludes by highlighting the need for an overhaul of the assessment and a reinforcement of teacher support and development.

An Investigation into the Development of Structure and Evidence Use in Argumentative Writing
Authors: Zhang Ying
Published: November 2018

This study aims to investigate EFL learners’ argumentative writing based on structural elements in Toulmin model (1953, 2008). It also explores the overall use of evidence in supporting claims. It was found that claim and data were the basic structural elements used by Chinese EFL learners in constructing argumentative writing. The respective use of counterargument data and rebuttal was significantly correlated with the quality of argumentation. In argumentative reasoning, the types of evidence and the number of evidence used by participants were very limited. Logical analysis was found to be the most frequently used data to support claims. Less proficient learners’ use of evidence was not effective or persuasive to produce valid argument. The findings provide useful insights into the instruction of argumentative writing for EFL teachers.

Flipped classroom is gaining more and more popularity among educators and researchers all over the world; however, its implementation in Viet Nam is still in infancy. This small-scale research project attempts to investigate students’ perceived challenges when attending a flipped English grammar class. Qualitative research design was adopted to address the research question. The participants include 34 second-year students majoring in the English language at a state university in Viet Nam. The instruments consist of an open-ended questionnaire and semi-structured interviews. Thematic analysis was employed to address the qualitative data. The findings highlight that Vietnamese students encounter several challenges when attending the flipped classroom including difficulty in self-regulated learning, heavy learning workload, lack of immediate support and lack of ICT resources. Accordingly, the present research has some pedagogical implications to help address those obstacles for successful implementation of this innovative teaching mode in the Vietnamese EFL context.

Published: November 2018

Plenty of study has been done about the Mobile Assisted Language Learning (MALL), which still hasn’t found its way into the English vocabulary learning. This empirical study aims to explore an effective way of vocabulary learning through the APP of WeChat on smart phones which are prevalently used among college students. 30 students participated in a WeChat group and were given word tests before and after the research respectively. A questionnaire survey was done a month later. The empirical result shows that it is easy for students to accept this new way of learning and most of them could follow the schedule. They have enhanced their self-regulation study ability and are encouraged to explore various methods to improve their study via smart phone Apps.
Language Learning Strategies Based On Gender

Published: November 2018

Gender as an individual characteristic has been proved to affect the use of strategies in learning a foreign language but how gender affects the use of strategies in learning a local language where the people in the community speak a national language is not explored yet.   Some studies show that female students employed language learning strategies more often than male students (Oxford & Nyikos, 1989; Awang Hashim & Syed Sahil, 1994;  Green and Oxford, 1995; Dreyer & Oxford, 1999). The present study was aimed to identify how gender affects the use of strategies in learning a local language in the environment where people in the country have a national language. A Non–probability sampling was used to collect data. With the Cronbach Alphas ranging from .79 to 82, mean scores of the use of language learning strategies the male and female students reported using were compared. In the present study it was found that metacognitive strategies were the strategies mostly used by female students and cognitive strategeis were the strategies mostly used by male students. This means that male students are likely to be more dependent on memorization than female students. Cognitive strategies which are characterized at least with memorization or rote learning in the present study tend to be used by male students.
