Attribute Selection for Stroke Prediction
Authors: Zdrodowska Małgorzata 
Published: December 2019

Abstract
Stroke is the third most common cause of death and the most common cause of long-term disability among adults around theworld. Therefore, stroke prediction and diagnosis is a very important issue. Data mining techniques come in handy to help determine the correlations between individual patient characterisation data, that is, extract from the medical information system the knowledge necessary to predict and treat various diseases. The study analysed the data of patients with stroke using eight known classification algorithms (J48 (C4.5), CART, PART, naive Bayes classifier, Random Forest, Supporting Vector Machine and neural networks Multilayer Perceptron), which allowed to build an exploration model given with an accuracy of over 88%. The potential features of patients, which may be factors that increase the risk of stroke, were also indicated.
Near-Surface Mass Defect in Models of Locally Heterogeneous Solid Mechanics
Authors: Nahirnyj Taras , Tchervinka Kostiantyn 
Published: December 2019

Abstract
This article deals with the model of the locally heterogeneous elastic body. The model accounts for long-range interaction and describes near-surface non-homogeneity and related size effects. The key systems of model equations are presented. From the viewpoint of the representative volume element, the boundary condition for density and the limits of applicability of the model are discussed. The difference of mass density in the near-surface body region from the reference value (near-surface mass defect) causes a non-zero stressed state. It is indicated on the strong dependence of the surface value of density from the curvature of the surface of thin fibres. The effect of the near-surface mass defect on the stressed state and the size effect of surface stresses have been investigated on an example of a hollow cylinder. Size effect of its strength has been studied as well.

Authors: Kołosowski Paweł , Wolniakowski Adam , Bogdan Mariusz 
Published: December 2019

Abstract
In the ever increasing number of robotic system applications in the industry, the robust and fast visual recognition and pose estimation of workpieces are of utmost importance. One of the ubiquitous tasks in industrial settings is the pick-and-place task where the object recognition is often important. In this paper, we present a new implementation of a work-piece sorting system using a template matching method for recognizing and estimating the position of planar workpieces with sparse visual features. The proposed framework is able to distinguish between the types of objects presented by the user and control a serial manipulator equipped with parallel finger gripper to grasp and sort them automatically. The system is furthermore enhanced with a feature that optimizes the visual processing time by automatically adjusting the template scales. We test the proposed system in a real-world setup equipped with a UR5 manipulator and provide experimental results documenting the performance of our approach.
Analyzing passing networks in association football based on the difficulty, risk, and potential of passes

Published: December 2019

Abstract
This paper investigates the use of network analysis to identify key players on teams, and patterns of passing within teams, in association football. Networks are constructed based on passes made between players, and several centrality measures are investigated in combination with three different methods for evaluating individual passes. Four seasons of data from the Norwegian top division are used to identify key players and analyze matches from a selected team. The networks examined in this work have weights based on three different aspects of the passes made: their probability of being completed, the probability that the team keeps possession after the completed pass, and the probability of the pass being part of a sequence leading to a shot. The results show that using different metrics and network weights leads to the identification of key passers in different phases of play and in different positions on the pitch.
Assessing the causal impact of the 3-point per victory scoring system in the competitive balance of LaLiga
Authors: Soto-Valero C , Pic M. 
Published: December 2019

Abstract
Competitive balance is a key concept in sport because it creates an uncertainty on the outcome that leads to increased interest and demand for these events. The Spanish Professional Football League (LaLiga) has been one of the top European leagues in the last decade, and it has given rise to a particular research interest regarding its characteristics and structure. Since season 1995/96, LaLiga changed the number of points given to the winning teams, by awarding three points per victory instead of two. In this paper, we assess the impact of such a change on the competitive balance of LaLiga. Our analysis focuses on teams with varying levels of performance and follows a three-step approach. First, we cluster the teams according to their historical performance using an adjusted measure based on their credible intervals of winning ratios. Second, we calculate Kendall’s tau coefficient (according to our adjusted measure) in order to obtain the overall ranking turnover of teams between consecutive seasons. Third, we assess the causal impact of the adoption of the new scoring system, based on Kendall’s tau coefficients, for each cluster of teams. Our results show that the overall competitive balance decreased after the adoption of the new scoring system. However, the impact was not the same for all teams, being more significant for top teams and less significant for bottom teams. Moreover, our predictions using adjusted ARIMA models indicate that this difference in the competitive balance will persist for future seasons.
The effects of age and body weight on powerlifters: An analysis model of powerlifting performance based on machine learning
Authors: Chau Vinh Huy , Vo Anh Thu , Le Ba Tuan 
Published: December 2019

Abstract
As a up and coming sport, powerlifting is gathering more and more attetion. Powerlifters vary in their strength levels and performances at different ages as well as differing in height and weight. Hence the questions arises on how to establish the relationship between age and weight. It is difficult to judge the performance of athletes by artificial expertise, as subjective factors affecting the performance of powerlifters often fail to achieve the desired results. In recent years, artificial intelligence has made groundbreaking strides. Therefore, using artificial intelligence to predict the performance of athletes is among one of many interesting topics in sports competitions. Based on the artificial intelligence algorithm, this research proposes an analysis model of powerlifters’ performance. The results show that the method proposed in this paper can predict the best performance of powerlifters. Coefficient of determination-R2=0.86 and root-mean-square error of prediction-RMSEP=20.98 demonstrate the effectiveness of our method.

Abstract
Nd3+ doped La2Ti2O7, Ce4+ doped Sm2Ti2O7 and Gd3+ doped Er2Ti2O7 have been synthesized at different reaction temperatures using solid state reaction method, and characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), differential thermal analysis (DTA), thermogravimetric analysis (TG). Excitation spectra, emission spectra and decay time curves of the samples were investigated by photoluminescence spectrophotometer (PL) and typical transitions of rare earth ions were observed. Dielectric properties, piezoelectric properties and Curie temperature of the obtained luminescent materials were measured for electrical characterization. The results showed that all materials have both photoluminescent and piezoelectric properties and show high Curie temperature.
Migration and wintering of Fieldfare (Turdus pilaris) in southeastern Hungary
Authors: Bozó László 
Published: December 2019

Abstract
The Fieldfare is a bird species widely distributed in the Palearctic region. In Hungary, the species is considered as a rare breeder and common, sometimes abundant migrant in autumn and spring, and also as winter visitor. It is prone to invasion, since northern breeding populations leave the breeding sites in large numbers only when the available food is inadequate or inaccessible to the birds. Most populations follow a southern-southwestern migration pattern, and in the course of their movement they also migrating through the Carpathian Basin. In this study, we examined the migration and wintering of the species in an area of southeast Hungary between 2004 and 2019. Data were collected between the beginning of October and the middle of April and during that period we saw Fieldfares a total of 416 times. In addition to the description of migration, the effect of weather on bird numbers was also investigated. According to our results, the species appears in the area in October and disappears in late March and the first half of April. The individuals that migrate in October are likely belonging to the Central European breeding population, while from November the Scandinavian birds can be seen. The maximum number of birds observed during the different years showed significant differences, as did the patterns of movements within the seasons. The relationship between the local weather and the number of birds has been demonstrated over several seasons, which is typical of species with an escape migration.
Leucistic Woodcock (Scolopax rusticola L.) occurrences in Hungary from the second half of the 19th century to the present day
Authors: Bende Attila , Király Angéla , lászló Richárd 
Published: December 2019

Abstract
Publications about curiosities are known in the Hungarian and international ornithological literature since the 1800s. Although studies explaining the processes of pigmentation dysfunctions have been known since the mid-nineteenth century, these specimens still appear only as curiosities in the professional press and the terminology used to specify them is generally incorrect. The analysed genetic abnormalities causing white colour varieties in Woodcock (albinism, leucism, Ino) are due to mutations. By briefly describing the biological background of the defects, this work helps detect colour changes. In this article, we provide a broad overview of partially or completely white Woodcocks (n = 23 expl.) found in international (8 countries) and Hungarian literature. We have supplemented the literature background with our own studies. The large-scale analysis of the variability of colours and patterns was made possible by the countrywide wing sample collection within the biometric module of Woodcock Monitoring, which has been running under the coordination of the Hungarian Hunting Conservation Association since 2010. Within this framework, 12,078 samples were analysed between 2010–2018. We found that pigment deficiency occurred in the sample set only with a proportion of 0.01%. Based on the Hungarian literature and our own samples, we presented the known occurrences on maps of the state territory with boundaries before and after 1921, indicating the causes of patterns of occurrence by migration and frequencies of occurrence.

Published: December 2019

AbstractThree species of lichenized basidiomycetes in the Dictyonema clade from southeastern North America are described as new to science: Cyphellostereum georgianum, C. jamesianum and Dictyonema lawreyi, all with a crustose-filamentous growth form. Based on ITS sequences, the species form well-supported monophyletic clades in a phylogeny and are represented by at least two specimens each. They are also distinguishable by morphological and anatomical characters. These new findings emphasize the importance of lichenological studies in North America, especially in historically understudied taxonomic groups, such as basidiolichens. This study is dedicated to James D. Lawrey on the occasion of his 70th birthday.
The Impact of Macro Factors on Apartment Prices in Polish Counties: A Two-Stage Quantile Spatial Regression Approach
Authors: Tomal Mateusz 
Published: December 2019

Abstract
The aim of this study is to identify the economic, demographic, environmental and spatial determinants of residential property prices in Polish counties. Two-stage quantile spatial regression (2SQSR) is the main method of analysis. Additionally, two-stage least squares regression (2SLS) is used.
The estimation results indicate that there are several significant determinants of residential property prices with observable quantile effects. In particular, the findings reveal a very interesting U-shaped pattern among quantile regression coefficients for variables describing unemployment rate, the standard of properties and county area. For the spatially lagged dependent variable, a linear pattern is observable.
Generally, the findings of this study have notable implications for developing housing policies, both at the national and local levels.
Application of AHP Method in Assessment of the Influence of Attributes on Value in the Process of Real Estate Valuation
Authors: Dmytrów Krzysztof , Gnat Sebastian 
Published: December 2019

Abstract
Property valuation in the comparative approach requires the determination of the impact of market characteristics on the formation of prices on the local real estate market. Valuers have a variety of methods for determining weights. Some of them require the collection of a sufficiently large database of information on transactions. However, this is not always possible. In the absence of sufficient data, alternative approaches, including an expert approach, may be used. The goal of the article is the proposal of an expert approach at the stage of assessing the influence of attributes on the value of the real estate. The AHP (Analytical Hierarchy Process) method will be used. On its basis, pairwise comparisons of the importance of attributes will be done by experts (valuers). By means of the AHP method, the weights of each attribute will be obtained and, subsequently, the influence of each attribute on the real estate value will be assessed. Research will be done on the basis of 318 real estates in Szczecin.
Hidden Public Value Identification of Real Estate Management Decisions
Authors: Kazak Jan K. , Simeunović Nataša , Hendricks Andreas 
Published: December 2019

Abstract
Seeing as how cities nowadays have to face many challenges (such as: urban traffic management, revitalization, and adaptation to climate change.), different kinds of urban policies and actions are undertaken. Many of these actions result in changes that influence real estate, mostly by improving the conditions of public services. However, implementation of such urban policies is connected with significant costs that have to be covered by public funds. Therefore, the question arises how we can analyze the assumed benefits from the increase of real estate value? Which tool could allow stakeholders to search for potential added value?
The aim of this paper is to present the methodological approach to improving the communication between stakeholders for the visualization of relations between public actions and potential benefits. The analyses cover benefits that can occur both in public and private budgets. The focal point of this paper is the presentation of causal loop diagrams as a tool that could be incorporated for public value identification on specific investments. The application of the suggested approach is visualized on two examples of urban redevelopment activities. Causal loop diagrams are prepared for the construction of a metro system and implementation of a water retention facility. The results show that both types of urban redevelopment actions have an impact on the creation of value, which can be observed both in public and private benefits. However, not all kinds of activities impact an increase in the market value of real estate and can be measured as incomes in budgets.

Published: December 2019

Abstract
Eco-innovation, as a new concept, and green technologies are central to the Europe’s future and at the core of the European Union policies to boost competitiveness, create jobs, and generate sustainable growth for years to come. In this context, eco-innovation is a significant tool that combines decreased environmental impact with a positive socioeconomic impact. This paper highlights the prominent role of eco-innovation and investigates still scarcely explored impact assessment of GDP growth, quality of institutions, and recycling rates on the eco-innovation index in the 28 European Union member states. Specifically, the set of regression analyses that use panel estimation models was undertaken and the system GMM estimator with robust standard errors was used. Econometric analysis indicates that GDP growth rate, quality of institutions, and recycling rate of municipal waste had a statistically significant and positive effect on eco-innovation in the period 2010-2016.

Published: December 2019

Abstract
This paper examines the return and volatility spillovers of different sectoral stock prices in Nigeria using monthly data from January 2007 to December 2016. We employ the Diebold and Yilmaz (2012) spillover approach and rolling sample analysis to capture the inherent secular and cyclical movements in the sector stocks market.We show that there is substantial difference between the behaviour of the sectoral stock return and volatility spillover indices over time. We find evidence of interdependence among sector stocks given the spillover indices. While the return spillover index reveals increased integration among the sectoral stocks, the volatility spillover index experiences significant bursts during major market crises. Interestingly, return and volatility spillovers exhibit both trends and bursts respectively.

Published: December 2019

On any given night, thousands of Canadian youth face homelessness in either absolute (living on the street) or relative (couch surfing, staying in emergency shelters) terms. This study explores influences primary health care access among youth experiencing homelessness in a large Canadian urban centre. Using a qualitative research design and convenience sampling, 8 youth participated in in-depth individual interviews and 4 clinicians with expertise in working with youth in primary care settings participated in a facilitated solutions-focused dialogue based on findings from the youth interviews. Data collection occurred from January to November 2016. Main findings included: (1) Youth experiencing homelessness feel powerless when interacting with health care providers, (2) Health care systems exist as rule-based bureaucracies and (3) Homeless youth are in survival mode when it comes to their health. The authors offer recommendations to promote more equitable access to primary health care services for homeless youth.

O Estágio Supervisionado é o percurso inicial para a inserção de professores em formação no universo escolar. Entretanto lacunas formativas nos cursos de licenciatura demandam cautela e reformulação. Investigando acerca da formação inicial no curso de Ciências Biológicas, este estudo visou promover um diálogo a respeito das concepções decorrentes das primeiras experiências de 12 licenciandos, enquanto professores estagiários da disciplina de Ciências. Neste viés, os dados foram angariados por meio de respostas a um questionário e analisados seguindo o embasamento teórico da Análise Textual Discursiva. As narrativas retrataram hiatos formativos e curriculares que refletiram o receio da responsabilidade docente, dificuldades em lidar com o desinteresse e indisciplina dos alunos e falhas na transposição didática. Todavia, também apontaram vivências construtivas da prática docente e amadurecimento de concepções. Assim, reestruturações curriculares carecem ser realizadas e, aliadas à disciplina de Estágio Supervisionado, podem promover um ambiente de reflexão e discussão a fim de ampliar conceitos, unir teoria e prática, oportunizando instrumentos fundamentais à ação docente.
