Authors: Brock Jeffrey , Leininger Christopher , Modami Babak , Rafi Kasra 
Published: June 2017

Abstract
Given a sequence of curves on a surface, we provide conditions which ensure that (1) the sequence is an infinite quasi-geodesic in the curve complex, (2) the limit in the Gromov boundary is represented by a nonuniquely ergodic ending lamination, and (3) the sequence divides into a finite set of subsequences, each of which projectively converges to one of the ergodic measures on the ending lamination. The conditions are sufficiently robust, allowing us to construct sequences on a closed surface of genus g for which the space of measures has the maximal dimension

, for example.
We also study the limit sets in the Thurston boundary of Teichmüller geodesic rays defined by quadratic differentials whose vertical foliations are obtained from the constructions mentioned above. We prove that such examples exist for which the limit is a cycle in the 1-skeleton of the simplex of projective classes of measures visiting every vertex.
Motivation of Civic Education Teachers-in-Training in the Field of Education for Sustainable Development
Authors: Hiller Katharina , Reichhart Barbara 
Published: June 2017

AbstractThe objective of teacher-training at university for political science is the development of professional competencies that enable teachers-in-training to act proficiently in all aspects of civic education. Although there are some studies that focus on civic education for teachers’ professional competencies, most of them relate to general capability and do not concern certain significant topics. Empirical results related to the definitive topics within civic education are scarce, particularly in the field of sustainable development. Questions arise regarding teacher-training where it relates to high self-efficacy and interest within the field of civic education compared to other subjects, based on the model of political competence by Detjen and colleagues. In this article, we present the results of a quasi-experimental trial with civic education teachers-in-training (N = 108). Results indicate that their self-efficacy in the field of sustainable development is low compared to other areas, although there is no significant difference in their level of interest in sustainable development compared to other topics.
Pedagogy is Coming Back! Some Hopeful Signs for Sustainable General Education and Worldview Education
Authors: Miedema Siebren 
Published: June 2017

AbstractNeo-liberal voices are still very strong in education broadly speaking and have a marginalizing impact on normative pedagogies like religious, worldview, moral and civic education. But there are clear and hopeful signs that pedagogy is coming back. After sketching the current situation and its antecedents, the author addresses the views and ideas here provided by pedagogical spokespersons, teacher-leaders and teachers – most of them working in the domain of religious education or worldview education. How do they perceive the current changes in more normative and pedagogical-laden directions? What precisely has caused these changes? Is the return of pedagogy just a temporal hype or is it a real revitalization? What have been the consequences for them professionally and personally speaking? It is the author’s intention and hope that this article will encourage educators in general and religious and worldview educators in particular with an eye on fostering sustainable pedagogical approaches.
Software Systems Clustering Using Estimation of Distribution Approach
Authors: Tajgardan Mahjoubeh , Izadkhah Habib , Lotfi Shahriar 
Published: June 2017

AbstractSoftware clustering is usually used for program understanding. Since the software clustering is a NP-complete problem, a number of Genetic Algorithms (GAs) are proposed for solving this problem. In literature, there are two wellknown GAs for software clustering, namely, Bunch and DAGC, that use the genetic operators such as crossover and mutation to better search the solution space and generating better solutions during genetic algorithm evolutionary process. The major drawbacks of these operators are (1) the difficulty of defining operators, (2) the difficulty of determining the probability rate of these operators, and (3) do not guarantee to maintain building blocks. Estimation of Distribution (EDA) based approaches, by removing crossover and mutation operators and maintaining building blocks, can be used to solve the problems of genetic algorithms. This approach creates the probabilistic models from individuals to generate new population during evolutionary process, aiming to achieve more success in solving the problems. The aim of this paper is to recast EDA for software clustering problems, which can overcome the existing genetic operators’ limitations. For achieving this aim, we propose a new distribution probability function and a new EDA based algorithm for software clustering. To the best knowledge of the authors, EDA has not been investigated to solve the software clustering problem. The proposed EDA has been compared with two well-known genetic algorithms on twelve benchmarks. Experimental results show that the proposed approach provides more accurate results, improves the speed of convergence and provides better stability when compared against existing genetic algorithms such as Bunch and DAGC.
Anti-stress effects of a GSK-3β inhibitor, AR-A014418, in immobilization stress of variable duration in mice
Authors: Bali Anjana , Jaggi Amteshwar Singh 
Published: June 2017

Abstract

Background:
The present study was designed to explore the anti-stress role of AR-A014418, a selective glycogen synthase kinase-3β inhibitor (GSK-3β), on changes provoked by immobilization stress of varying duration.

Methods:
Acute stress of varying degree was induced by subjecting mice to immobilization stress of short duration (30 min) or long duration (120 min). Thereafter, these animals were exposed to the same stressor for 5 days to induce stress adaptation. The behavioral alterations were assessed using an actophotometer, a hole-board, and the open field and social interaction tests. The serum corticosterone levels were assessed as markers of the hypothalamic-pituitary-adrenal (HPA) axis activity. The levels of total GSK-3β and p-GSK-3β-S9 were determined in the prefrontal cortex.

Results:
A single exposure to short or long immobilization stress produced behavioral and biochemical changes and the levels of p-GSK-3β-S9 decreased without affecting the total GSK-3β levels in the brain. However, repeated exposure to both short and long stress reversed the behavioral and biochemical changes along with the normalization of p-GSK-3β-S9 levels. The administration of AR-A014418, a selective GSK-3β inhibitor, diminished acute stress-induced behavioral and biochemical changes. Furthermore, AR-A014418 normalized acute stress-induced alterations in p-GSK-3β-S9 levels without changing total GSK-3β levels.

Conclusions:
Our study suggests that acute stress-induced decrease in p-GSK-3β-S9 levels in the brain contributes to the development of behavioral and biochemical alterations and the normalization of GSK-3β signaling may contribute to stress adaptive behavior in mice which have been subjected to repeated immobilization stress.
On the constitutive equations of fresh mortar
Authors: Kakavas P.A. , Konstantinidis A. , Hatzitrifon N.K. , Papadopoulos P. , Aifantis E.C. 
Published: June 2017

AbstractA preliminary constitutive model is suggested for fresh mortar by taking into account the rheological properties of the base matrix (concrete matrix), as well as the interaction of the aggregates (concrete suspensions). The model may be applicable for interventions in monuments and restoration/protection of objects of cultural heritage.
Thrombectomy combined with indwelling-catheter thrombolysis is more effective than pure thrombectomy for the treatment of lower extremity deep venous thrombosis
Authors: Wang Wenli , Wu Yanfang , Fang Tao , Xu Dunyuan 
Published: June 2017

Abstract
This study was a retrospective analysis of the efficacy of thrombectomy plus local catheter-directed thrombolysis (CDT) for the treatment of lower extremity deep venous thrombosis (LDVT).
The experimental group underwent thrombectomy plus LCDT, whereas the control group underwent thrombectomy plus systemic thrombolysis via the dorsalis pedis vein. Venography and vascular color Doppler ultrasound were performed 7 days after surgery and at follow-up. The differences in the thigh and calf circumferences of normal and affected limbs were compared between groups. The venous patency score and venous patency rate were used for outcome evaluation. Compared with the control group, the experimental group showed a lower venous patency score and higher venous patency rate after treatment (P<0.05). Thirty patients were followed for 3 to 6 months, and according to the last evaluation, the differences in thigh and calf circumference between the normal and affected limbs remained lower in the experimental group than in the control group (P<0.05). Moreover, the venous patency score was lower, and the venous patency rate was higher in the experimental group than in the control group (P<0.05).

Conclusion
Thrombectomy plus CDT yields a higher venous patency rate and lower recurrence rate than pure thrombectomy for the treatment of LDVT.

\geq \frac{|{f^{(n)}(z)}|}{n!}\quad\text{for all}\,\, n. $$

The main goal of this paper is extend this notion to holomorphic bivariate function. To that end, we obtain the following definition. A holomorphic bivariate function is of bounded index, if there exist two integers M and N such that M and N are the least integers such that

Using this notion we present necessary and sufficient conditions that ensure that a holomorphic bivariate function is of bounded index.
Asymptotic expansion of double Laplace-type integrals with a curve of minimal points and application to an exit time problem
Authors: Benaissa Abdallah , Benlahcene Moussa 
Published: June 2017

AbstractIn this paper we consider the problem of the asymptotic expansion of double Laplace-type integrals, in the case when the setγof points where the phase achieves its absolute minimum is a simple curve. It will be shown that the asymptotic behaviour of such integrals is governed by the order of degeneracy of normal derivatives of the phase with respect to the curveγ. Complete asymptotic expansions will be constructed if that order is constant alongγ, and the first two coefficients will be explicitly computed. If not, a uniform asymptotic expansion method, involving special functions, is suggested.
Modelling prescription behaviour of general practitioners
Authors: Hudecová Šárka , Pešta Michal , Hlubinka Daniel 
Published: June 2017

Abstract
The health care costs have been rapidly rising in recent years and the public health insurance companies are highly interested in prescription policies of general practitioners. In our contribution, a complex model for prescription behaviour of Belgian general practitioners is built using the structural equation modelling (SEM) framework. The model involves a large number of prescribed medicament groups as well as doctors’ and patients’ characteristics. As one of the results, a relatively small number of medicament groups, which effectively describe the prescription behaviour of a given doctor, is obtained. These indicators are consequently used in a generalized linear model for predicting the drug expenses per patient. Such a model can be used as a useful guideline for the expenses’ assessment of a particular practitioner.
Biosensing with optical fiber gratings
Authors: Chiavaioli Francesco , Baldini Francesco , Tombelli Sara , Trono Cosimo , Giannetti Ambra 
Published: June 2017

AbstractOptical fiber gratings (OFGs), especially long-period gratings (LPGs) and etched or tilted fiber Bragg gratings (FBGs), are playing an increasing role in the chemical and biochemical sensing based on the measurement of a surface refractive index (RI) change through a label-free configuration. In these devices, the electric field evanescent wave at the fiber/surrounding medium interface changes its optical properties (i.e. intensity and wavelength) as a result of the RI variation due to the interaction between a biological recognition layer deposited over the fiber and the analyte under investigation. The use of OFG-based technology platforms takes the advantages of optical fiber peculiarities, which are hardly offered by the other sensing systems, such as compactness, lightness, high compatibility with optoelectronic devices (both sources and detectors), and multiplexing and remote measurement capability as the signal is spectrally modulated. During the last decade, the growing request in practical applications pushed the technology behind the OFG-based sensors over its limits by means of the deposition of thin film overlays, nanocoatings, and nanostructures, in general. Here, we review efforts toward utilizing these nanomaterials as coatings for high-performance and low-detection limit devices. Moreover, we review the recent development in OFG-based biosensing and identify some of the key challenges for practical applications. While high-performance metrics are starting to be achieved experimentally, there are still open questions pertaining to an effective and reliable detection of small molecules, possibly up to single molecule, sensing in vivo and multi-target detection using OFG-based technology platforms.
The Interpersonal Pollution and its Effect on Group Members’ Well-Being, and on Culture of Unity in Organizational Context
Authors: Pietrulewicz Bogdan 
Published: June 2017

AbstractThe new concept of “interpersonal pollution” and its antecedents and effects, i.e. on organizational members’ health and well-being and on organizational outcomes are investigated. Building upon this work this presentation proposes a model and tentative definition of a broader construct, i.e. “organizational pollution”, and identifies its potential antecedents and explores its impact on humans’ health and well-being and organizational outcomes. In particular our model explores the roles played by leaders’ and members’ dark personalities and lack of environmental concern, by unethical leadership, by both the characteristics of the community and the organization, including the latter’s physical and ethical environment, and finally their link to organizational pollution. This new model implications for organizational and environmental psychology are discussed.
Marital Dialogue – between Conflict, Agreement and Relationship Breakdown
Authors: Kornaszewska-Polak Monika 
Published: June 2017

Abstract
Marital dialogue plays an essential role in shaping the relationship between spouses and supports experiencing personal I in the context of the community – We. In these couples, where dialogue is going well, it fulfils the function of a secure base forming a community based on the foundation of unity. However, contemporary culture denies an interpersonal dialogue the authenticity and engagement, emphasizing individualistic attitudes, preoccupation with oneself, leading to relationship and community disintegration and breakdown. This paper is to present the authors twenty year research into bonds, communication styles, marital conflicts and ways of coping with them. The research shows various issues related to developing the interpersonal dialogue and thus creating bonds and unity in the marriage and family. At first, the research devoted to the transmission of generation patterns in the family is presented and it is followed by presentation of selected psychological factors influencing marriage quality and marital satisfaction.

AbstractIntroduction. A review of Polish and international literature does not give a clear indication of the level of anaerobic capacity that sailors with disabilities demonstrate with regard to their functional capacities. This study sought to determine differences in functional capacity levels between sailors from three medical and functional groups. Material and methods. The research was carried out during a sports camp at the National Sailing Centre in Górki Zachodnie in 2014. Eighteen males with locomotor disabilities were included in the study. The athletes were members of the National Team of Sailors with Disabilities of the Polish Yachting Association. The sportsmen competed in the Skud 18 and 2.4mR Paralympic classes. A 30-second Wingate test for upper limbs was employed in the study. Results. Significant differences in mean power (MP) values were noted between the groups under investigation. The group of wheelchair sailors with improper core stability (A) and the group of wheelchair sailors with proper core stability (B) had significantly lower scores than the group of study participants who were able to move freely, that is to walk (C). Conclusions. The study revealed that a 30-second anaerobic capacity test performed on an arm ergometer differentiated disabled sailors from selected groups in terms of mean power. Research on anaerobic capacity may be used to verify the current classification in Paralympic sailing and will make it possible to differentiate present competition categories.

Published: June 2017

Abstract
Introduction. The aim of the study was to determine the quality of life of students of a University of the Third Age (U3A) and examine its correlations with demographic variables, physical fitness, perception ability, and emotional well-being. Material and methods. The study involved 116 women aged 50 to 88 years who participated in U3A classes held at the University of Physical Education in Warsaw. Quality of life was assessed using an abridged version of the WHOQOL-BREF questionnaire. Additionally the Fullerton Functional Fitness Test, a dynamometer hand grip strength test, and Romberg’s test were performed. The Attention and Perceptiveness Test (version 6/9) by Ciechanowicz and Stańczak, the UMACL Mood Adjective Checklist by Matthews, Chamberlain, and Jones, as well as the Geriatric Depression Scale by Yesavage were also used. Finally, data concerning age, marital status, economic status, chronic diseases, and medication use was collected with a specially designed questionnaire. Results. The U3A students who took part in the study perceived their quality of life as relatively high. The domain of quality of life which was found to be the most strongly correlated with demographic variables was the psychological health domain: scores in this domain decreased with the subjects’ age and increased with their level of education and economic status. Health satisfaction was directly proportional to economic status and inversely proportional to the level of education. Depression scores correlated significantly negatively with quality of life scores in all domains, the overall perception of quality of life, and health satisfaction, as well as predicting quality of life in the domains of psychological health and the environment. The predictors of the subjects’ perceived quality of life were the following: lower body strength, agility, flexibility, and aerobic endurance. Conclusions. The findings of the study confirm that demographic variables (age, education, and economic status), depression and mood, as well as physical fitness are important predictors of quality of life in women in late adulthood.
A Linguistic Evaluation of Rule-Based, Phrase-Based, and Neural MT Engines

Published: June 2017

AbstractIn this paper, we report an analysis of the strengths and weaknesses of several Machine Translation (MT) engines implementing the three most widely used paradigms. The analysis is based on a manually built test suite that comprises a large range of linguistic phenomena. Two main observations are on the one hand the striking improvement of an commercial online system when turning from a phrase-based to a neural engine and on the other hand that the successful translations of neural MT systems sometimes bear resemblance with the translations of a rule-based MT system.
Pre-Reordering for Neural Machine Translation: Helpful or Harmful?
Authors: Du Jinhua , Way Andy 
Published: June 2017

AbstractPre-reordering, a preprocessing to make the source-side word orders close to those of the target side, has been proven very helpful for statistical machine translation (SMT) in improving translation quality. However, is it the case in neural machine translation (NMT)? In this paper, we firstly investigate the impact of pre-reordered source-side data on NMT, and then propose to incorporate features for the pre-reordering model in SMT as input factors into NMT (factored NMT). The features, namely parts-of-speech (POS), word class and reordered index, are encoded as feature vectors and concatenated to the word embeddings to provide extra knowledge for NMT. Pre-reordering experiments conducted on Japanese↔English and Chinese↔English show that pre-reordering the source-side data for NMT is redundant and NMT models trained on pre-reordered data deteriorate translation performance. However, factored NMT using SMT-based pre-reordering features on Japanese→English and Chinese→English is beneficial and can further improve by 4.48 and 5.89 relative BLEU points, respectively, compared to the baseline NMT system.
Comparing Language Related Issues for NMT and PBMT between German and English
Authors: Popović Maja 
Published: June 2017

Abstract
This work presents an extensive comparison of language related problems for neural machine translation and phrase-based machine translation between German and English. The explored issues are related both to the language characteristics as well as to the machine translation process and, although related, are going beyond typical translation error classes. It is shown that the main advantage of the NMT system consists of better handling of verbs, English noun collocations, German compound words, phrase structure as well as articles. In addition, it is shown that the main obstacles for the NMT system are prepositions, translation of English (source) ambiguous words and generating English (target) continuous tenses. Although in total there are less issues for the NMT system than for the PBMT system, many of them are complementary – only about one third of the sentences deals with the same issues, and for about 40% of the sentences the issues are completely different. This means that combination/hybridisation of the NMT and PBMT approaches is a promising direction for improving both types of systems.
