Midwives' experiences of caring for women with early pregnancy loss in an Irish maternity hospital
Authors: Nash Mary , Barry Maebh , Bradshaw Carmel 
Published: December 2018

Background Midwives provide care for women experiencing early pregnancy loss, as well as support for women throughout childbirth. Research has predominately focused on women's experience of early pregnancy loss, with little research on how such loss affects midwives and care provision. Aim To explore the perceptions of midwives caring for women experiencing early pregnancy loss. Methods This study used a descriptive qualitative design with semi-structured interviews. A purposive sample of eight midwives, all of whom had relevant experience, were recruited from a maternity hospital in Ireland. Findings Themes identified were: ‘coping with the experience of early pregnancy loss’, ‘compassionate care for women and midwives’, and ‘what midwives found difficult’. Conclusions Repeated exposure to early pregnancy loss can have a profound emotional effect on midwives, with a potential for this to affect the care that women receive. Midwives identified the need for further education in the area of early pregnancy loss, time out during the shift to debrief, and counselling for staff. Structured support is needed for midwives and other health professionals where there is repeated exposure to early pregnancy loss.
Ansätze für eine lernförderliche Arbeitsgestaltung 4.0
Authors: Cernavin Oleg 
Published: December 2018

ZusammenfassungAutonome technische Systeme werden die Bedingungen für eine lernförderliche Arbeitsgestaltung verändern. Erstmals in der Technikgeschichte können autonome technische Systeme Handlungsträgerschaft übernehmen und damit auch das Lernen im Arbeitsprozess erheblich beeinflussen. Die mit dieser Entwicklung verbundenen Ambivalenzen eröffnen Gestaltungsmöglichkeiten für ein lernförderliches Arbeiten. Die neuen Technologien können aber sowohl zu neuen autoritären Strukturen als auch zu einer produktiven, humanen und partizipativen Förderung der reflexiven Handlungsfähigkeit und der beruflichen Handlungskompetenz führen. Um die Gestaltungspotenziale zu nutzen, sollte größere Klarheit bei den in diesen Entwicklungen genutzten Begriffen hergestellt werden.
Lernförderliche Arbeitsgestaltung in der Sachbearbeitung – eine Aufgabe für Team- und Gruppenleitungen?
Authors: Richter Götz , Mühlenbrock Inga , Ribbat Mirko 
Published: December 2018

ZusammenfassungOrganisationen stehen vor der Herausforderung, ihre Beschäftigten auf die digitale Transformation vorzubereiten. Das Lernen bei der Arbeit (arbeitsintegriertes Lernen) kann dabei eine Schlüsselstrategie sein. In diesem Beitrag werden sachbearbeitende Tätigkeiten als Kernfunktion der Verwaltung in den Blick genommen. Es wird der Frage nachgegangen, wie Kompetenzentwicklung, Gesundheit und Zufriedenheit der Beschäftigten durch Lernförderung auf Tätigkeits-, Führungs- und Organisationsebene verbessert werden können. Grundlage dafür ist eine quantitative Befragung von Team- und Gruppenleitungen (n = 144) sowie ihren Mitarbeiterinnen und Mitarbeitern (n = 538) in Verwaltungen von Kommunen und Finanzdienstleistern. Es kann gezeigt werden, dass Lernförderlichkeit auf jeder Ebene positiv mit Arbeitszufriedenheit, Kompetenzeinschätzung und Gesundheit der Beschäftigten zusammenhängt. Führungskräfte werden als entscheidende Treiber für arbeitsintegriertes Lernen identifiziert, die jedoch unterstützende Rahmenbedingungen benötigen.
Exoskeleton transparency: feed-forward compensation vs. disturbance observer

Published: December 2018

Abstract
Undesired forces during human-robot interaction limit training effectiveness with rehabilitation robots. Thus, avoiding such undesired forces by improved mechanics, sensorics, kinematics, and controllers are the way to increase exoskeleton transparency.
In this paper, the arm therapy exoskeleton ARMin IV+ was used to compare the differences in transparency offered by using the previous feed-forward model-based controller, with a disturbance observer in a study. Systematic analysis of velocity-dependent effects of controller transparency in single- and multi-joint scenarios performed in this study highlight the advantage of using disturbance observers for obtaining consistent transparency behavior at different velocities in single-joint and multi-joint movements. As the main result, the concept of the disturbance observer sets a new benchmark for ARMin transparency.
Ein eigennütziger houptman der wâren zuht?
Authors: Fuhrmann Daniela 
Published: December 2018

Abstract
This article discusses in detail the figure of Gurnemanz who, in book III of ›Parzival‹, acts as the hero’s teacher in courtly behaviour. By analysing the episode in its immediate context, I expose selfish tendencies leading Gurnemanz’s guidance, tendencies which, together with further features, link Gurnemanz to other advisors in the novel. His education can thus be seen not only as a fundamental part of the novel’s syntagmatic, but also of its paradigmatic structure. I show that – in comparison to Chrétien – Wolfram’s narration problematises the topic ›zuht and rât‹, underlining the ambiguities in his teaching figures. This shift, in the end, supports the idea of an individuated hero.
Differential expression of DLG1 as a common trait in different human diseases: an encouraging issue in molecular pathology
Authors: Marziali Federico , Dizanzo María Paula , Cavatorta Ana Laura , Gardiol Daniela 
Published: December 2018

Abstract
Human disc large (DLG1) is a scaffolding protein that through the interaction with diverse cell partners participates in the control of key cellular processes such as polarity, proliferation and migration. Experimental data have mainly identified DLG1 as a tumor suppressor. An outstanding point for DLG1 protein is that altered DLG1 expression and DLG1 gene mutations were observed in different pathologies, including cancer and neurological and immunological disorders. Evident changes in DLG1 abundance and/or cell localization were identified in a number of studies suggesting its participation in molecular mechanisms responsible for the development of such illnesses. In this review, we focus on some of the latest findings regarding DLG1 alterations in different diseases as well as its potential use as a biomarker for pathological progression. We further address the current knowledge on the molecular mechanisms regulating DLG1 expression and the posttranslational modifications that may affect DLG1 cell localization and functions. Despite the advances in this field, there are still open questions about the precise molecular link between alterations in DLG1 expression and the development of each specific pathology. The complete understanding of this concern will give us new scenarios for the design of promising diagnosis and therapeutic tools.
Peptide binding affinity redistributes preassembled repeat protein fragments
Authors: Michel Erich , Plückthun Andreas , Zerbe Oliver 
Published: December 2018

Abstract
Designed armadillo repeat proteins (dArmRPs) are modular peptide binders composed of N- and C-terminal capping repeats Y and A and a variable number of internal modules M that each specifically recognize two amino acids of the target peptide. Complementary fragments of dArmRPs obtained by splitting the protein between helices H1 and H2 of an internal module show conditional and specific assembly only in the presence of a target peptide (Michel, E., Plückthun, A., and Zerbe, O. (2018). Peptide-guided assembly of repeat protein fragments. Angew. Chem. Int. Ed. 57, 4576–4579). Here, we investigate dArmRP fragments that already spontaneously assemble with high affinity, e.g. those obtained from splits between entire modules or between helices H2 and H3. We find that the interaction of the peptide with the assembled fragments induces distal conformational rearrangements that suggest an induced fit on a global protein level. A population analysis of an equimolar mixture of an N-terminal and three C-terminal fragments with various affinities for the target peptide revealed predominant assembly of the weakest peptide binder. However, adding a target peptide to this mixture altered the population of the protein complexes such that the combination with the highest affinity for the peptide increased and becomes predominant when adding excess of peptide, highlighting the feasibility of peptide-induced enrichment of best binders from inter-modular fragment mixtures.

Abstract

Background
Prenatal care in adolescents is one of the most important challenges worldwide, especially in the regions with a specific culture and traditions. The purpose of this study was to investigate the effectiveness of group counseling on knowledge and performance of pregnant adolescents in prenatal care in a Kurdish region in Iran.

Methods
This quasi-experimental study was conducted on pregnant adolescents attending in the health centers of Mahabad, a Kurdish city in Iran. Using a multi-stage cluster sampling method, after random selection of four health centers as the intervention and the control, primigravida adolescents with gestational age of 16–20 weeks filled out the demographic and midwifery characteristics questionnaire, as well as a prenatal care knowledge and performance of pregnant adolescents’ questionnaire. Then 102 pregnant adolescents (51 people in the control centers and 51 people in the intervention centers), who responded correctly to <50% of the questionnaire items were included in the study. Six sessions of group counseling about prenatal care were held for the intervention group. The control group received the routine prenatal care. Knowledge and performance of pregnant adolescents about prenatal care were compared inter and intra two groups 1 month after the end of the sessions through descriptive-analytic tests including chi-square, independent T and paired T tests.

Results
In contrast to the control group, the mean scores of adolescents’ knowledge about prenatal care increased after the intervention (from 17.51 ± 5.93 to 24.67 ± 5.79) and showed significant difference to the control group (p < 0.05). In addition, the mean scores of adolescent care performance in the intervention group increased (from 5.80 ± 2.19 to 10.33 ± 2.55) and showed significant difference to the control group (p < 0.05).

Conclusion
The results of the present study show the positive effects of prenatal care counseling on increasing knowledge and improving the performance of pregnant adolescents.
Deep Convolutional Neural Networks for the Prediction of Molecular Properties: Challenges and Opportunities Connected to the Data
Authors: Ståhl Niclas , Falkman Göran , Karlsson Alexander , Mathiason Gunnar , Boström Jonas 
Published: December 2018

Abstract
We present a flexible deep convolutional neural network method for the analysis of arbitrary sized graph structures representing molecules. This method, which makes use of the Lipinski RDKit module, an open-source cheminformatics software, enables the incorporation of any global molecular (such as molecular charge and molecular weight) and local (such as atom hybridization and bond orders) information. In this paper, we show that this method significantly outperforms another recently proposed method based on deep convolutional neural networks on several datasets that are studied. Several best practices for training deep convolutional neural networks on chemical datasets are also highlighted within the article, such as how to select the information to be included in the model, how to prevent overfitting and how unbalanced classes in the data can be handled.

Authors: Méjri Bochra 
Published: December 2018

Abstract
This work is devoted to the study of the void identification problem from partially overdetermined boundary data in the 2D-elastostatic case. In a first part, a shape identifiability result from a Cauchy data is presented, i.e. with traction field and boundary displacement as measurements. Then this geometric inverse problem is tackled by the minimization of two cost functionals, an energy gap functional and an

Performance of Hybrid OCDMA/WDM Scheme Under DPSK and QPSK Modulation Using Spectral Direct Detection Technique for Optical Communication Networks
Authors: Ahmed N. , Rashid M. A. 
Published: December 2018

Abstract
The hybrid optical code-division multiple-access over wavelength-division multiplexing (OCDMA/WDM) scheme has attractive features of supporting system reach, multi Gbps data rates, security, and robustness for optical communication networks. This paper presents the performance of such scheme under DPSK and QPSK modulation formats using spectral direct detection technique. The modified double weight (MDW) code is used as spectral amplitude coding which also acts as a signature address code for the OCDMA system. The MDW code has the advantage of reducing the multiple access interference (MAI) and enhancing the security of the proposed hybrid system. The study focuses on the comparison between the two advanced modulation techniques (DPSK, QPSK) using spectral direct detection. Simulation results show bit-error-rate (BER) ≤10–09 for up to 25 km distance at the bit rate of 1 Gbps for optical communication networks.
Electrostatic Force Microscopy Measurement System for Micro-topography of Non-conductive Devices
Authors: He Gaofa , Meng Jie , Tan Renbing , Zhong Peng 
Published: December 2018

AbstractA home-made electrostatic force microscopy (EFM) system is described which is directed toward assessment of the microscopic geometry of the surface of specimens made of non-conductive material with a large thickness. This system is based on the variation in the electrostatic force between the conductive probe and the non-conductive specimen in order to get its surface morphology. First, based on the principle of dielectric polarization, the variation rules of the electrostatic force between the charged probe and the non-conductive specimen were studied. Later, a special tuning fork resonant probe unit made of quartz crystal was fabricated for measurement of the electrostatic force, and the scanning probe microscopic system in the constant force mode was constructed to characterize the three-dimensional micro-topography of the surface of the specimen. Finally, this system was used to perform scanning measurement experiments on the indented surface of the specimen made of the polyvinyl chloride (PVC) material with thickness 3 mm. In the present experimental system, when the external voltage was 100 V and the distance from the probe tip to the specimen surface approximately 100 nm, the variance in the resonant frequency of the probe unit was around 0.5 Hz. These results indicate that this home-made EFM system can effectively characterize the micro-topography of the non-conductive specimen with very large thickness which is above several millimeters.

How Animacy and Natural Gender Constrain Morphological Complexity: Evidence from Diachrony
Authors: Igartua Iván , Santazilia Ekaitz 
Published: December 2018

AbstractIn addition to its central role in the organization of gender systems and its numerous effects on different parts of the grammar, animacy reveals itself as a significant, sometimes even determinant factor in diachronic processes like the reduction of morphological complexity. Complexity in the realm of inflection may be defined as the extent to which formal distinctions in paradigms are semantically or phonologically unmotivated and therefore largely unpredictable on extramorphological grounds. Animacy and natural (or sex-based) gender emerge in certain cases as features capable of constraining this kind of complexity by offering a transparent semantic criterion that helps substantiate several formal distinctions in languages, thereby reducing the amount of morphological complexity or unpredictability inherited from earlier stages in the evolution of different linguistic systems.
Archive as Medium
Authors: Dressler Virginia A. 
Published: December 2018

AbstractThis article will explore the idea of the archive as medium, with sub-themes of neutrality, silence, and truth. An archive can serve as the intermediary in the construction of the archival series and collections around a central theme or scope. The messages bound in the archival container are selected to fit into an archival series or collection to reiterate or document a particular aspect. Archival collections have the power and effect of creating cumulative viewpoints over time by way of the contained messages. Selected case studies of more recent user-generated digital archives will be explored in context to these themes; such as A People’s Archive of Police Violence in Cleveland and Take Back the Archive (University of Virginia).
Transient thermal regime trough the constitutive matrix applied to asynchronous electrical machine using the cell method
Authors: González-Domínguez Pablo Ignacio , Monzón-Verona José Miguel , García-Alonso Santiago 
Published: December 2018

Abstract
In this paper, a new constitutive matrix for thermal conduction in transient thermal regime is developed and tested. We use cell method as a numerical method that is included in finite formulation methodology. The constitutive matrix defines through the cell method the behavior of solids when they are under a thermal potential. We have demonstrated that this matrix is equivalent to the electrical conduction constitutive matrix in steady state. We have applied this constitutive matrix to thermal analysis of asynchronous electric machines in transient regime. This constitutive matrix has been validated with comparisons based on finite element method. In finite formulation, the physical laws governing the electromagnetic fields and the physical thermal phenomena are expressed in integral formulation. The final algebraic equation system is tailored directly without discretizing of the differential equations. This is an important advantage because we omit a complex differential formulation and the discretization of the respective equations.

Authors: Roca José Luis , Rodríguez-Bermúdez German , Fernández-Martínez Manuel 
Published: December 2018

AbstractAlong this paper, we shall update the state-of-the-art concerning the application of fractal-based techniques to test for fractal patterns in physiological time series. As such, the first half of the present work deals with some selected approaches to deal with the calculation of the self-similarity exponent of time series. They include broadly-used procedures as well as recent advances improving their accuracy and performance for a wide range of self-similar processes. The second part of this paper consists of a detailed review of high-quality studies carried out in the context of electroencephalogram signals. Both medical and non-medical applications have been deeply reviewed. This work is especially recommended to all those researchers especially interested in fractal pattern recognition for physiological time series.
Posttraumatic Stress Symptoms in Victims of the Tokyo Subway Sarin Attack: Twenty Years Later
Authors: Nakamine Shin , Kobayashi Maiko , Fujita Hiroyuki , Takahashi Sachiko , Matsui Yutaka 
Published: December 2018

Introduction: Previous studies found that about 10–30% of terrorist attack survivors suffer mental disorders such as posttraumatic stress disorder (PTSD) which persist up to 10 years. However, little is known about whether the effects of terrorism on mental health could last for a longer period or whether physical symptoms and secondary victimization are associated with the persistence of mental disorders. Method: A questionnaire survey was conducted with the victims of the Tokyo subway sarin attack in March 1995 (N = 299). Victims’ physical and ophthalmic symptoms, secondary victimization, and posttraumatic stress symptoms were surveyed. For comparison, those who have experienced a stressful event were surveyed with the same instruments as of victims’ survey except secondary victimization. Results: Results indicated that 21.3% of the male and 36.1% of the female victims were in the high-risk group for posttraumatic stress symptoms (PTSS), which did not differ from those of the comparison group. However, victims had physical and ophthalmic symptoms of greater severity than the comparison group. Moreover, we found that PTSS was strongly associated with physical symptoms and secondary victimization. Discussion: There is a need to develop a support system that would be helpful in reducing mental health suffering of terrorist victims. Providing regular physical checkups and building support for those who experience life changes caused by victimization are suggested.
Use of Social Psychology to Improve Adherence to National Bronchiolitis Guidelines
Authors: Sprecher Eli , Chi Grace , Ozonoff Al , Cox Joanne , Patel Nolan , Conroy Kathleen 
Published: December 2018

OBJECTIVES:
The American Academy of Pediatrics’ bronchiolitis guidelines recommend against albuterol and corticosteroids for treating and chest radiographs (CRs) for diagnosing infants with bronchiolitis. However, high rates of nonadherence have been documented. Our objective was to improve guideline adherence in infants with bronchiolitis.

METHODS:
This quality improvement study was conducted in 1 urban academic pediatric primary care clinic caring for predominately minority and publicly insured children. We tested provider guideline education, display of guidelines in patient care areas, and monthly e-mails to all providers documenting deviation rates, with individual e-mails to providers who deviated. P-charts and interrupted time series analysis were used to estimate the effect of the intervention.

RESULTS:
There were 380 children &lt;2 years of age with a diagnosis of bronchiolitis in the 16 nonsummer months preintervention and 417 in the 15 postintervention months. Rates of prescribed and administered albuterol declined from 45.7% in the baseline period to 13.7% in the intervention period and CR use dropped from a mean of 10.1% to 3.4%, both demonstrating special cause variation. Steroid use did not change significantly. In interrupted time series analyses, the intervention was associated with a significant decrease in albuterol use (P &lt; .001) but not in CR or steroid use. Emergency department visits declined slightly but admissions for bronchiolitis were stable.

CONCLUSIONS:
Traditional quality improvement efforts coupled with social psychology techniques resulted in improved guideline adherence in outpatient bronchiolitis management. Additional study will help identify which techniques are most effective for increasing guideline adherence in cases of low-value care.
