Background Detecting renal allografts with impaired function early after renal transplantation and timely intervention are important to ensure a successful outcome. Purpose To detect impaired function of renal allografts at the early stage after renal transplantation using intravoxel incoherent motion imaging (IVIM). Material and Methods Forty-six recipients with good allograft function and 32 recipients with impaired function were included in this study. All participants were scanned with IVIM using 11 b-values on a 3-T magnetic resonance (MR) scanner; the apparent diffusion coefficient (ADC), ADC of slow diffusion (ADCslow), pseudo-diffusion (ADCfast), and perfusion fraction (f) values were calculated using a full bi-exponential model. Correlations between estimated glomerular filtration rate (eGFR) and the IVIM parameters were assessed by using Spearman correlation analysis. Receiver operating characteristics were used to assess the diagnostic utilities for detecting allografts with impaired function. Results The ADC, ADCslow, ADCfast, and f values of the renal cortex and the ADC and ADCslow values of the renal medulla were significantly higher in allografts with good function compared to those with impaired function (all P < 0.05). There was a significant corticomedullary difference in ADCslow, ADC, and f in all allografts. ADCfast values were higher in the cortex than in the medulla for allografts with good function but no differences were seen in allografts with impaired function ( P > 0.05). Combined use of all cortical IVIM parameters has higher efficacy in detecting renal allograft dysfunction than any single parameter (sensitivity = 90.62%; speciﬁcity = 78.26%). Conclusion IVIM technique may be useful for detecting renal allograft dysfunction, especially combined use of cortical parameters.

Objective To assess the safety and efficacy of external trigeminal nerve stimulation for acute pain relief during migraine attacks with or without aura via a sham-controlled trial. Methods This was a double-blind, randomized, sham-controlled study conducted across three headache centers in the United States. Adult patients who were experiencing an acute migraine attack with or without aura were recruited on site and randomly assigned 1:1 to receive either verum or sham external trigeminal nerve stimulation treatment (CEFALY Technology) for 1 hour. Pain intensity was scored using a visual analogue scale (0 = no pain to 10 = maximum pain). The primary outcome measure was the mean change in pain intensity at 1 hour compared to baseline. Results A total of 109 participants were screened between February 1, 2016 and March 31, 2017. Of these, 106 patients were randomized and included in the intention-to-treat analysis (verum: n = 52; sham: n = 54). The primary outcome measure was significantly more reduced in the verum group than in the sham group: −3.46 ± 2.32 versus −1.78 ± 1.89 ( p < 0.0001), or −59% versus −30% ( p < 0.0001). With regards to migraine subgroups, there was a significant difference in pain reduction between verum and sham for ‘migraine without aura’ attacks: mean visual analogue scale reduction at 1 hour was −3.3 ± 2.4 for the verum group versus −1.7 ± 1.9 for the sham group ( p = 0.0006). For ‘migraine with aura’ attacks, pain reduction was numerically greater for verum versus sham, but did not reach significance: mean visual analogue scale reduction at 1 hour was −4.3 ± 1.8 for the verum group versus −2.6 ± 1.9 for the sham group ( p = 0.060). No serious adverse events were reported and five minor adverse events occurred in the verum group. Conclusion One-hour treatment with external trigeminal nerve stimulation resulted in significant headache pain relief compared to sham stimulation and was well tolerated, suggesting it may be a safe and effective acute treatment for migraine attacks. Study protocol ClinicalTrials.gov Identifier: NCT02590939.

Published: November 2018

Background and Objective Some individuals with migraine report the presence of speech changes during their migraine attacks. The goal of this study was to compare objective features of speech during the migraine pre-attack, the migraine attack, and during the interictal period. Methods This was a prospective, longitudinal, observational study of adults with episodic migraine and healthy non-migraine controls. Participants provided speech samples three times per day using a speech elicitation tool included within a mobile app. Six complementary speech features that capture articulation and prosody were extracted from speech samples. Participants with migraine maintained a daily headache diary using the same app. A mixed effects model and t-tests were used to investigate differences in speech features between controls, the migraine pre-attack phase, the migraine attack, and the interictal period. Results In total, 56,767 speech samples were collected, including 43,102 from 15 individuals with migraine and 13,665 from matched healthy controls. Significant group-level differences in speech features were identified between those with migraine and healthy controls and within the migraine group during the pre-attack vs. attack vs. interictal periods (all p < .05). Most consistently, speech changes occurred in the speaking rate, articulation rate and precision, and phonatory duration. Within-subject analysis revealed that seven of 15 individuals with migraine showed significant change in at least one speech feature when comparing the migraine attack vs. interictal phase and four showed similar changes when comparing the pre-attack vs. interictal phases. Conclusions Changes in speech occurred in almost half of the individuals during migraine attacks. Once confirmed in subsequent studies, speech changes could be considered a feature of the migraine attack.

Published: November 2018

Royal Melbourne Hospital (RMH) performs over 140 kidney transplant operations annually. Kidney transplant recipients require regular medical review, which results in loss of time and costs from travel, particularly for regional patients, and places high demand on the hospital outpatient service. The RMH renal transplant unit initiated a telehealth service in 2016 to provide cost effective, patient-centred clinical care for regional patients. To date, 263 clinical reviews have been conducted via telehealth, potentially saving 203,202 kilometres in travel distance; 2771 hours in car travel time; an estimated AUD $31,048 in petrol savings and 51 tonnes CO2 equivalents of greenhouse gas emissions. Lessons learnt have included the importance of using technology that allows patients to access telehealth from their place of choice. The option of a joint consultation with local healthcare providers has facilitated the development of extended care networks for our patients. Incorporation of telehealth into our outpatient system has been achieved with the existing nephrology workforce, making it a sustainable long-term review option. Our renal transplant telehealth outpatient clinic has been a successful change in the way we provide care to regional patients. Formal comparison of clinical outcomes and the patient experience of telehealth versus in person reviews are underway.

Published: November 2018

BackgroundFew studies have determined the very long‐term mortality risks in adult and childhood‐diagnosed coeliac disease.ObjectiveWe quantified mortality risks in coeliac disease and determined whether age at diagnosis, or time following diagnosis, modified these risks.MethodsStandardised 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.ResultsAll‐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).ConclusionsAdult‐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

Abstract
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

Abstract
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

Abstract
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.
Die Quantifizierung von Nicht-Routine
Authors: Pfeiffer Sabine 
Published: November 2018

ZusammenfassungIn 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

Abstract
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

Published: November 2018

Abstract
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.

Authors: Wang Xiumei , Yuan Jihai , Zhai Haorui 
Published: November 2018

Abstract
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.

Published: November 2018

Abstract
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.
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.
