Markov regime-switching autoregressive model with tempered stable distribution: simulation evidence
Authors: Feng Lingbing , Shi Yanlin 
Published: May 2019

Abstract
Markov regime-switching (MRS) autoregressive model is a widely used approach to model the economic and financial data with potential structural breaks. The innovation series of such MRS-type models are usually assumed to follow a Normal distribution, which cannot accommodate fat-tailed properties commonly present in empirical data. Many theoretical studies suggest that this issue can lead to inconsistent estimates. In this paper, we consider the tempered stable distribution, which has the attractive stability under aggregation property missed in other popular alternatives like Student’s t-distribution and General Error Distribution (GED). Through systematically designed simulation studies with the MRS autoregressive models, our results demonstrate that the model with tempered stable distribution uniformly outperforms those with Student’s t-distribution and GED. Our empirical study on the implied volatility of the S&P 500 options (VIX) also leads to the same conclusions. Therefore, we argue that the tempered stable distribution could be widely used for modelling economic and financial data in general contexts with an MRS-type specification.

Assessment of Three-Dimensional Printing of Granular Media for Geotechnical Applications
Authors: Adamidis O. , Alber S. , Anastasopoulos I. 
Published: May 2019

Abstract
The rapid evolution of three-dimensional (3-D) printing has sparked interest for possible applications in geotechnical research. This article investigates the use of 3-D printing to create an artificial granular medium that reproduces the morphological characteristics of a natural sand. Initially, individual particle geometries are captured from the reference sand using microcomputed tomography (μCT) scanning. Subsequently, their capacity to represent the morphology of the original medium is assessed. An evaluation of 3-D-printing options ensues, leading to the selection of PolyJet as the currently preferential technology. Postprinting, μCT scanning reveals that only particles with a diameter of 2 mm or larger can be reliably reproduced using PolyJet. Finally, 3-D-printed media are assessed for their performance in possible geotechnical applications by examining their hydraulic conductivity using a constant head permeameter and their shear response using drained triaxial compression tests.
ALG-1 Influences Accurate mRNA Splicing Patterns in the Caenorhabditis elegans Intestine and Body Muscle Tissues by Modulating Splicing Factor Activities

Published: May 2019

Abstract
MicroRNAs (miRNAs) are known to modulate gene expression, but their activity at the tissue-specific level remains largely uncharacterized. To study their contribution to tissue-specific gene expression, we developed novel tools to profile putative miRNA targets in the Caenorhabditis elegans intestine and body muscle. We validated many previously described interactions and identified ∼3500 novel targets. Many of the candidate miRNA targets curated are known to modulate the functions of their respective tissues. Within our data sets we observed a disparity in the use of miRNA-based gene regulation between the intestine and body muscle. The intestine contained significantly more putative miRNA targets than the body muscle highlighting its transcriptional complexity. We detected an unexpected enrichment of RNA-binding proteins targeted by miRNA in both tissues, with a notable abundance of RNA splicing factors. We developed in vivo genetic tools to validate and further study three RNA splicing factors identified as putative miRNA targets in our study (asd-2, hrp-2, and smu-2), and show that these factors indeed contain functional miRNA regulatory elements in their 3′UTRs that are able to repress their expression in the intestine. In addition, the alternative splicing pattern of their respective downstream targets (unc-60, unc-52, lin-10, and ret-1) is dysregulated when the miRNA pathway is disrupted. A reannotation of the transcriptome data in C. elegans strains that are deficient in the miRNA pathway from past studies supports and expands on our results. This study highlights an unexpected role for miRNAs in modulating tissue-specific gene isoforms, where post-transcriptional regulation of RNA splicing factors associates with tissue-specific alternative splicing.
La otredad de la filosofía. Miguel de Unamuno y la función de la razón
Authors: Andersen Katrine Helene 
Published: May 2019

El pensamiento español ha sido marginalizado dentro de la historia de la filosofía europea hasta principios del siglo XX, en gran parte debido a su carácter literario y su falta de doctrinas sistemáticas, pero en especial debido al concepto de la razón. La razón lógico-especulativa nunca tuvo la misma influencia en España que en el resto de Europa, y con Miguel de Unamuno el concepto de la razón y su función filosófica se problematiza explícitamente. El presente estudio analiza y discute la definición y la función de la razón en la filosofía unamuniana. Analiza la relación entre la razón y el lenguaje y entre la razón y la fe. Además, se discuten las consecuencias de su escepticismo hacia la primacía de la razón para su visión del hombre y para su método filosófico.<p><strong><br /></strong></p><p> </p><p> </p>

An analysis of sexist language in interpersonal relations - A study on linguistic communication in higher education
Authors: Carrillo Victoria del Rocio Gomez , Rodriguez Esther Mena , Jimenez Miguel Angel Fernandez 
Published: May 2019

This project aims to analyse the perceptions of university students about the use of language, as its correct use constitutes an important element for the development of gender equality. We question the idea that in university teaching, language is free of sexism and claim that this sexism is more evident in some branches of knowledge than in others. To this end, we will analyse the degree of importance attributed to language across different branches of knowledge and the identification of sexist expressions in daily use. The methodology used is based on a survey and interview. Different groups belonging to different degree courses of the academic communities of the Universities of Malaga and Seville participated in the research. Following this analysis, we reflect on the language use prevailing in the university environment since it constitutes a central space of action for its educational and socializing mission.
Keywords: Sexist language, discrimination, students, university, communication and education.
Exploring the relationship between teacher professionality and occupational experience
Authors: Leibur Tiiu , Saks Katrin , Chounta Irene-Angelica 
Published: May 2019

Professional development is a key process within the wider agenda of raising standards and increasing societal growth capacity by improving teaching policy and practice in education. The aim of the research was to explore the relations between teacherâ€™s professionality and occupational qualifications. Forty teachers were asked to estimate their pedagogical, core and holistic representation competencies. The correlation analysis was applied to investigate the relations between the length of employment and the competencies. The results indicated positive but weak correlations that suggest the relationship between learning gains and development need as well as between assessment and targeted feedback. A negative but still weak correlation was found between the length of employment and ensuring physical, mental and emotional wellbeing. Future work will focus on elaborating the instrument used in this study as well as the experimental setup in order to gain further insights and reliable results.

Authors: Anastasiadou Sofia D 
Published: May 2019

The Big Five Personality Traits very well known as five-factor model (FEM), which is a taxonomy for personality traits, has a an effect on Transformational School Leadership and Leaders. Personality traits are the most powerful pylons for raising educational standards and achieving excellence based on the effectual Leadership. Openness to experience, conscientiousness, extraversion, agreeableness and neuroticism constitute the FEM. Transformational School Leadership model that comprises an essential element of quality assurance is based on the constructs of Setting Directions, Developing People, Redesigning the Organisations, Reliability of Administrative Leadership. Measures of Teachersâ€™ Capacities, Measures of Teachersâ€™ Motivation, Measures of Teachersâ€™ Work Setting and Measures of Teachersâ€™ Classroom Practices. To test the research hypotheses, a survey was carried out on 215 Greek secondary education teachers teaching in vocational lyceums, senior high schools in Greece. Moreover, 215 Greek secondary Vocational education teachers evaluate the effect of Personality Traits and characteristics on Transformational Vocational School Leadership and Leaders.

Logic and heuristic in education
Authors: Naziev Aslanbek 
Published: May 2019

More than once were suggested that the results of the field of logic appear to be useful at the checking of ready-made proofs but refused to serve when one has to discover evidence; although some very reputable mathematicians supported this view, we allow ourselves to disagree with it. Every time they offer arguments for this point of view (and very often it speaks without any arguments), they demonstrate a â€˜frontalâ€™, straightforward interpretation of the results of logic. However, such an interpretation of the interrelations between logic and heuristic is not the only possible one. On the contrary, other interpretations possible, in which logic and heuristics are two sides of the single process of learning. In our paper, we consider both mentioned uses of the logic.
Keywords: Intuitive evidence, logical proof, heuristic advices.
Build history through educational competences in the degree of primary education
Authors: Molina Torres Maria Pilar 
Published: May 2019

This work collects the results obtained from the teaching innovation project called: â€˜Building History through educational competences in the Degree of Primary Educationâ€™, carried out in the course 2017/2018. Different educational competences present in the curricular projects related to the area of Social Sciences were worked during its development. During the proposal, several practical activities will be carried out, such as small research works during the visit to the Archaeological Museum of Cordoba and the realisation of historical models related to the chosen theme in the didactic itinerary that will be included in a group classroom blog. The interaction of two different branches of knowledge (Social Sciences and Humanities) allowed us to work in an interdisciplinary way to concretise in practice the different activities. In fact, the purpose of this didactic experience is the application of these activities by the students to take them to a real classroom context.

GeoGebra application, used in the determination of the magnitude of an earthquake
Authors: Chiriacescu Bogdan 
Published: May 2019

In this paper, the authors tackle the earthquakes study with the aim of determining the magnitude. By means of a GeoGebra program (an open source programme), we encourage the secondary school scholars in modelling the data obtained from an actual earthquake. We intend to obtain the magnitude of an earthquake by a method that can be easily comprehended by the students. The model is based on Richterâ€™s approach. In order to facilitate the process, a GeoGebra application was created that allows for an accurate calculus. The instrument presented in this paper assists in a better understanding of the Richter scale (including how it was built) and the correlation between the energy released by the earthquake, the amplitude of the waves and the epicentral distance. The students will be able to analyse a seismogram, to identify its main elements and to determine the magnitude of a simulated earthquake.

Contextual learning strategies in the early stages of architecture education
Authors: Sahin Murat 
Published: May 2019

The main objective of this paper is to present a series of interconnected contextual learning strategies applied in the early stages of architecture education. The study presents the design and implementation process of a term project assigned to first-year architecture students. It applied the contextual learning strategies by combining the autobiographical memory and design problem to explore unique narrative structure. This method allows for aligning multiple contexts-course content, the objective of the course, students profile, the learning environment and the basis of the design disciplines. The process was a performative one that involves storytelling, video making, quasi-research skills and informal discussions with parents and guardians to uncover and present the changing nature of the urban fabric as seen and understood by students. The results show that the students engaged and unearth various material within the contextual paradigm.
Keywords: Narrative reflection, contextual learning, alignment, architectural education.
The intervention: Improving social-emotional skills in early childhood as a factor of school performance
Authors: Monica Coste 
Published: May 2019

Contemporary studies show the major impact of early education on the future development of children, that justifies a quality educational approach from the early childhood, to meet the needs of childrenâ€™s education for the onset of schooling. The dynamics of society and the updates in the field of education make it necessary to create an educational context as a response of the current needs of childrenâ€™s competencies. In many countries, social-emotional education gains importance as an essential element of education, emotional intelligence being considered a determinant for success in life. The methods used were the pedagogical experiment, surveys, curricular analysis and systematic observation. When children experience well-being, the ability to think is increased. The active involvement of the teachers in the implementation of the programme, the use of recommended practices and the solving of the challenges that have appeared have led to an increase in the impact of the intervention.

This study used qualitative research in the form of exploratory research, namely descriptive analysis. The population was all Islamic Elementary Schools (MI) in Pamekasan, and four schools were selected as samples by using purposive sampling technique.</p><p>The results showed that from the aspect of designing effective and meaningful learning, as well as in organizing learning, found that MI Islamiyah I Larangan Tokol, Tlanakan did not implement K-13 and did not have Arabic subject syllabus, and so did MI As-Salafi Sumber Duko Pakong. Even, the condition found in MIN 1 Konang, Galis as one of the State Islamic Elementary Schools in Pamekasan is almost the same as the Private Madrasah, because even though they have an Arabic subject syllabus, but it was still in print out syllabus, and the file is not formally legalized by the head of Madrasah. While, in the implementation of learning, it is revealed that teachers were not able to maximize the community, environment, media, and to utilize available internet connection in the learning practice. It happened in almost all Madrasah. Also, teachers of Madrasah Ibtidaiyah in Pamekasan need more training, guidance, and self-improvement in understanding the K-13 concept wholly and comprehensively. On the other hand, Madrasah Ibtidaiyah in Pamekasan did not yet maximize the K-13 concept in term of environmental empowerment as learning resources, and even it is undiscovered the use of andragogy approach, scientific approach, and active learning that should be applied in learning Arabic in Madrasah Ibtidaiyah in Pamekasan.</p><p>In general, there are three inhibiting factors which caused the difficulty in the implementation of K-13 in Madrasah Ibtidaiyah in Pamekasan; those include Madrasah and Government’s Policy, lack of qualified teachers, and inadequate facilities.

Consistent Model for Injection and Falloff Pressure Match of Diagnostic Fracture Injection Tests (DFITs)
Authors: Liu G.. , Ehlig–Economides C.. 
Published: May 2019

Summary
The diagnostic fracture injection test (DFIT), a fracture–injection/falloff test, is a reliable tool for quantifying the formation of closure stress, leakoff coefficient, formation permeability, and pressure. The current analytical DFIT model (used before and after closure) enables one to match the pressure falloff of abnormal leakoff behaviors, and quantifies more formation parameters than a traditional DFIT model. However, this model design addresses only the falloff data after shut–in; thus, analysts have expressed concerns that the net pressure implied by the falloff is inconsistent with the injection pressure behavior. Therefore, this paper provides a model capable of matching both injection and falloff pressure behaviors.
The pressure–falloff model is capable of quantifying essential pressure values including, in order of occurrence, instantaneous shut–in pressure (ISIP), minimum fracture–propagation pressure, one or more closure–stress values, formation minimum principal stress, and pore pressure. The early pressure response represents the dissipation of three kinds of friction—wellbore, perforation, and near–wellbore friction. Each of them is quantified, and, together, they comprise the difference between the pressure at the end of injection and the ISIP. Presence of tip extension enables the quantification of the minimum fracture–propagation pressure. The minimum principal stress is consistent with the final closure stress. Subtracting the closure stress and friction pressure losses from the recorded or calculated bottomhole pressure (BHP) provides the fracture net pressure. The model match for injection pressure behavior incorporates the same pressures and consistent values for 2D fracture geometry and leakoff coefficient.
The global match confirms not only the estimation of formation and fracture properties from the pressure–falloff analysis, but also the friction losses along the wellbore, through the perforations, and in the near–wellbore tortuosity during and after injection. In particular, by matching both injection and falloff, the model incorporates friction pressure losses that can explain apparent excessive net pressure.
The match with both injection and falloff pressure variation addresses concerns that the net pressure implied by the falloff model match cannot be consistent with the observed injection behavior. When the pressure difference between the final DFIT pick for closure stress and the pressure at the end of injection is large, the reason might be tip extension and/or large friction pressure losses, the latter of which can be addressed by the main treatment design.
Reimagining Maize Inbred Potential: Identifying Breeding Crosses Using Genetic Variance of Simulated Progeny
Authors: Beckett Travis J. , Rocheford Torbert R. , Mohammadi Mohsen 
Published: May 2019

ABSTRACTProper choice of parents for breeding populations is essential in developing new maize (Zea mays L.) inbreds for improved hybrid performance. Breeders have frequently chosen parental combinations based on mid‐parent (MP) value, or predicted progeny mean, to combine favorable traits from the two parents. When two breeding populations have the same MP value, an accurate prediction of progeny variance may reveal which population has a greater potential for genetic gain. In this study we used available inbred genotypes and new hybrid phenotypes from 246 inbreds with expired Plant Variety Protection certificates and 39 historically important North American dent inbreds, all test crossed to Iodent inbred PHP02. We used the R package ‘PopVar’ to simulate biparental populations and perform genome‐wide prediction to predict the progeny mean, genetic variance, and superior progeny mean for grain yield, grain moisture, and test weight within each virtual population. Breeding crosses were ranked based on the mean grain yield of superior progeny and correlated trait responses for test weight and moisture. Results show that combining germplasm from different proprietors in new breeding crosses can produce inbreds with improved performance in a hybrid test cross. The simulation and prediction model presented in this study may help breeders to identify parental pairs with the greatest potential for genetic gain in hybrid crop breeding programs.
