Published: December 2017

Abstract
The aim of this study was to compare the effects of high-intensity small-sided games training (SSGT) versus repeated-sprint training (RST) on repeated-sprint ability (RSA), soccer specific endurance performance and short passing ability among junior soccer players. The junior soccer players were recruited from of a professional team (age 16.9 ± 1.1 years). The tests included the repeated-shuttle-sprint ability test (RSSAT), Yo-Yo Intermittent Recovery Test level 1 (Yo-Yo IR1) and Loughborough Soccer Passing Test (LSPT). Nineteen participants were randomly assigned to either the small-sided games training (SSGTG) (n = 10) or repeated-sprint training group (RSTG) (n = 9). Small-sided games or repeated-sprint training were added to the regular training sessions for two days of the regular practice week. The Wilcoxon signed-rank and Mann-Whitney U tests were used to examine differences in groups and training effects. A time x training group effect was found in the improvement of short-passing ability for the smallsided games training group which showed significantly better scores than the repeated-sprint training group (p ≤ 0.05). Both groups showed similar improvements in RSAdecrement (p < 0.05). Only the repeated-sprint training group improved in the Yo-Yo IR1 (p < 0.05). This study clearly shows that high-intensity small-sided games training can be used as an effective training mode to enhance both repeated sprint ability and short-passing ability.

AbstractIn wheelchair sports, aerobic performance is commonly assessed with the use of an arm crank ergometer (ACE), a wheelchair ergometer (WCE) or a wheelchair treadmill (WCT). There are different protocols to identify peak oxygen uptake in wheelchair sports; however, only a few protocols have been applied to evaluate these conditions in wheelchair basketball players. The purpose of this study was to compare physiological responses during maximal exercise testing with the use of ACE and WCT in wheelchair basketball players. Twelve elite male wheelchair basketball players participated in this study. The research was performed during a training camp of the Polish National Wheelchair Basketball Team. The study participants were divided into two functional categories: A (players with class 1.0 - 2.5) and B (players with class 3.0 - 4.5). Two main maximal exercise tests, i.e. wheelchair treadmill stress test (WCT test) and arm crank ergometer stress test (ACE test) were used to evaluate aerobic performance of the players. There were no statistically significant differences in aerobic tests between the players from both groups. The comparison of results achieved in two aerobic tests performed on WCT and ACE did not reveal any significant differences between the analyzed variables (peak heart rate (HRpeak), peak oxygen uptake (VO2peak), minute ventilation (VE), anaerobic threshold (AT), lactate concentration (LApeak), and a drop in lactate concentration (%LA)). Strong correlations between results achieved in WCT and ACE tests were found for VO2peak, VE and LApeak. The main conclusion of the study is that both WCT and ACE tests may be useful when determining aerobic capacity of wheelchair basketball players. Moreover, both protocols can be used by athletes regardless of their functional capabilities and types of impairment.

ABSTRACT
A computational cost comparative study through both Java and C applications was developed. Computational routines consist of a matrix multiplications, the discrete cosine transform and the bubble-sorting algorithm. Memory and Runtime for each application were measure. It was determined that the runtime of matrix multiplication in Java was within the limits of 200 and 300 milliseconds, as opposed to the application developed in C, which shown to be stable with an execution period less than 20 milliseconds. In the ordering algorithm with the bubble method, it was observe that the Java language show be very slow compared to C. In addition, the memory usage was lower in most of the applications, showing a minimum difference. Applications were tested in both, a mobile LG-E510f and a Laptop Toshiba Satellite. The study allowed to report the profit generated in both runtime and memory consumption when performing a native implementation in C and Java.
Implementation of Feedback Supporting Formative Assessment Into Mathematical Digital Learning Materials
Authors: Lukáč Stanislav , Sekerák Jozef 
Published: December 2017

ABSTRACTOfficial documents of educational policy of the European Union highlight the importance of integrating ICT into education. Interactive learning materials play an important role in the meaningful use of ICT to support an active learning. Providing feedback dependent on student´s actions should be a standard part of the digital learning materials. The immediate feedback in the classroom during the learning process is in most cases provided by the teacher. The importance of feedback even increases when students work with the digital learning materials independently in the classroom or at home. Moreover, ICT tools offer a great potential for detecting and eliminating students' mistakes. A notification of a concrete type of error in student’s way of task solution and guiding students during the corrections of their solutions creates conditions for application of formative assessment which provides suggestions to students for improving their learning. The effectiveness of feedback depends on the way how the typical errors of students are taken into account and what way the appropriate hints are implemented in learning. Various forms of feedback should be implemented in the interactive learning materials in order to stimulate the active learning. In many available the digital learning materials there is often a minimal feedback provided on student´s solution of a certain task. This paper discusses the implementation of various types of feedback in an interactive mathematics learning environment. Even though the minimal feedback can stimulate the active learning, it may not be sufficient for some types of students who do not think deeply about their methods of problem solving. Higher levels of feedback are characterized by providing comments that depend on student's mistakes and by providing pieces of advice and other helpful additional information that are closely related to the solution of tasks. The diagnosis of typical student´s misconceptions was based on the analysis of the results of the prepared tests, which were given to students at high school. Demonstrations of the minimal feedback and higher levels of feedback are illustrated in the examples of fractions, percentages and investigation of function dependencies. The interactive learning materials are developed using Geogebra and MS Excel.
An Improved Particle Swarm Optimization Algorithm for Global Multidimensional Optimization
Authors: Fajr Rkia , Bouroumi Abdelaziz 
Published: December 2017

Abstract
This paper introduces a new variant of the particle swarm optimization (PSO) algorithm, designed for global optimization of multidimensional functions. The goal of this variant, called ImPSO, is to improve the exploration and exploitation abilities of the algorithm by introducing a new operation in the iterative search process. The use of this operation is governed by a stochastic rule that ensures either the exploration of new regions of the search space or the exploitation of good intermediate solutions. The proposed method is inspired by collaborative human learning and uses as a starting point a basic PSO variant with constriction factor and velocity clamping. Simulation results that show the ability of ImPSO to locate the global optima of multidimensional functions are presented for 10 well-know benchmark functions from CEC-2013 and CEC-2005. These results are compared with the PSO variant used as starting point, three other PSO variants, one of which is based on human learning strategies, and three alternative evolutionary computing methods.

Abstract

Objective:
The aim of the present study was to assess, in a population of dichorionic twin pregnancies with selective growth restriction, the effect of inter-twin differences by use of Doppler velocimetry and fetal growth discordancy on perinatal outcomes.

Methods:
This was a retrospective study including dichorionic twin pregnancies from January 2008 to December 2015 at the Department of Obstetrics and Gynecology of Fondazione MBBM. Only dichorionic twin pregnancies affected by selective intrauterine growth restriction (IUGR) delivering at ≥24 weeks were included in the study.

Results:
We found that twin pregnancies with inter-twin estimated fetal weight (EFW) discordance ≥15% were significantly associated with a higher risk of preterm delivery before 32 (P=0.004) and 34 weeks (P=0.04). Similarly, twin pregnancies with inter-twin abdominal circumference (AC) discordance ≥30° centiles were associated with a higher rate of neonatal intensive care unit (NICU) admission (P=0.02), neonatal resuscitation (P=0.02) and adverse neonatal composite outcome (P=0.04). Of interest, when comparing twin pregnancies according to Doppler study, growth restricted twins had a higher rate of composite neonatal outcome and in multivariate analysis, an abnormal Doppler was an independent risk factor for this outcome.

Conclusions:
Our study associated growth discrepancy with specific pregnancy outcomes, according to defined cut-offs. In addition, we demonstrated that an abnormal umbilical artery Doppler is independently associated with a composite neonatal adverse outcome in growth restricted fetuses.
Processing Metaphors in the Elderly: Does Valence Matter?
Authors: Bartczak Marlena 
Published: December 2017

Abstract
Much evidence from theory and research points towards difficulties in processing metaphors by elderly people. These difficulties are usually associated with working memory and inhibitory control deficits observed in this age group, as these very functions play a crucial part in efficient metaphor processing. However, results of research on understanding metaphorical content by elderly people are inconclusive. The following article reviews studies showing that metaphor processing relies on a set of complex variables, which might explain the inconclusiveness of previous results. Though we acknowledge the role of interindividual factors (differences in cognitive functioning among the elderly), we focus on the properties of the metaphor stimuli themselves, especially those of conventionalization and valence, as they might influence the processing of verbal metaphors by people in older age groups.

Abstract
Following up on the previous special issue of Psychology of Language and Communication, devoted to irony, the current one concerns metaphors - another major form of non-literal language. The authors of the presented papers examine metaphor use and understanding in a wide variety of contexts, both in adult and child, as well as normal and abnormal populations. The result is a comprehensive survey of the current state of research, which opens further avenues of potentially fruitful inquiry.
Delayed discounting of pain with and without monetary reward
Authors: Kicman Paweł , Bąbel Przemysław 
Published: December 2017

Abstract
We investigated the effect of monetary rewards on the rate of pain discounting. Our aim, also, was to understand the effect of previous painful dental experiences on the rate of discounting pain. Two groups (N = 148) completed a discounting task. In the first group, delayed pain was weaker than immediate pain, and in the second group delayed pain was stronger than immediate pain. Two conditions were studied: pain was either accompanied by a monetary reward or not. We found that people preferred immediate pain when it was weaker than delayed pain; however, when delayed pain was stronger than immediate pain, there was no clear preference. In both groups the preference for immediate pain was higher when pain was accompanied by a monetary reward. Previous painful experiences were not related to the rate of discounting. It was concluded that the preference for delayed pain depends on the intensity of pain, and it can be modified by rewards that accompany pain.
English as a Foreign Language Learners’ Anxiety and Interlocutors’ Status and Familiarity: An Idiodynamic Perspective
Authors: Shirvan Majid Elahi , Talebzadeh Nahid 
Published: December 2017

AbstractForeign language learning anxiety has been the target of many studies in the field of applied linguistics, but, with the dynamics turn in the field, attempts have been recently made to uncover the dynamics of anxiety English as a foreign language (EFL) learners go through, especially within the moments of their conversational interactions. Within these interactions, dynamics of anxiety might emerge in different patterns under the influence of the status of the participants’ interlocutors and their familiarity with them. This study explores the dynamics of EFL learners’ anxiety while interacting with different interlocutors from an idiodynamic perspective. The participants of this case study were two female freshman students, taking a speaking and listening university course, who were interviewed by four interlocutors with different status and level of familiarity. Following an idiodynamic method, they self-rated their anxiety fluctuations under the influence of each interlocutor throughout each conversation followed by stimulated recall interviews regarding the explanations of the changes in their anxiety during the conversations. The results showed both change and stability in the participants’ anxiety under the influence of the interlocutors’ familiarity with the participants and their status as well their verbal and nonverbal feedback. The explanation of these changes based on the main properties of complex dynamic system theory is discussed.
Shortening of psychological tests – assumptions, methods and doubts
Authors: Kleka Paweł , Paluchowski Władysław Jacek 
Published: December 2017

Abstract
In this article, on the basis of questionnaire data collected for other purposes, the Authors want to show the consequences of various methods of shortening of tests and what may result from such an action for diagnosticians, researchers and examined individuals. The research aim of the work is to show the best method of shortening of the scale of questionnaires. Will shortening of a questionnaire according to different statistical techniques bring the same results? Will the quality of shortened scales be comparable? Is any of statistical techniques better for shortening of the scale of a questionnaire? The obtained results suggest a poorly controlable effect of the methods of questionnaire shortening. Moreover creating a short version on the basis of the results collected with the use of the full version leads to obtaining a tool with unknown diagnostic and psychometric properties.
Is profitability a good proxy for efficiency? Evidence from the subsector of tour operators
Authors: Hedija Veronika , Fiala Roman , Kuncová Martina 
Published: December 2017

AbstractThe goal of the paper is to evaluate the economic efficiency of tour operators in the Czech Republic in the period 2007-2014 using data envelopment analysis (DEA) models and prove the link between economic efficiency and profitability and to find out if profitability is a good proxy for economic efficiency. Data was exported from the database Albertina CZ Gold Edition. We calculated the efficiency score using CCR (Charnes, Cooper and Rhodes) and BCC (Banker, Charnes and Cooper) models based on 3 inputs and 1 output. In the years 2007 to 2010, the efficiency score of almost all the companies was higher than 0.5; however, in years since 2011, we revealed significant differences in the efficiency of individual firms and only about 40 percent of tour operators achieved an efficiency score higher than 0.5. Using Pearson and Spearman correlation coefficients, our findings show that, in the case of the Czech tour operator market, profitability ratios do not correspond with firm efficiency. Profitability ratios are not a good proxy for economic efficiency and should not be used as the only firm criterion of performance.
Earnings Quality and Investment Efficiency: Evidence from Eastern Europe
Authors: Cherkasova Victoria , Rasadi Daryush 
Published: December 2017

Abstract
This study explores the firm-level relationship between earnings quality and investment efficiency. Higher quality of reported results has the capacity to positively impact the efficiency of company’s investment levels by over- and underinvestment reduction. The research is carried out on the sample of 7546 companies from Eastern Europe for the period 2010-2015. Eastern European countries have a unique institutional and business environment that is relevant to the purpose of this paper. We divide the sample into 2 fundamentally different economic sectors - industrial and retail - and test the significance of each factor in the main relationship. We also examine the factor of the firm’s ownership form by comparing earnings quality with investment efficiency values between public and private companies. Our main results show that a higher earnings quality mitigates both overinvestment and underinvestment issues. The relationship between earnings quality and underinvestment turns out to be stronger in the industrial sector. As for the comparison of public and private firms, public companies on average demonstrate a higher earnings quality and lower overinvestment issues.

Abstract
The correct and complete diagnosis is essential for the adequate care and the favourable clinical evolution of the patients with head trauma. Purpose: To identify the error rate in the clinical diagnosis of head injuries as shown in comparison with the autopsy diagnosis and to identify the most common sources of error. Material and method: We performed a retrospective study based on data from the medical files and the autopsy reports of patients with head trauma who died in the hospital and underwent forensic autopsy. We collected: demographic data, clinical and laboratory data and autopsy findings. To quantify the concordance rate between the clinical diagnosis of death and the autopsy diagnosis we used a 4 classes classification, which ranged from 100% concordance (C1) to total discordance (C4) and two classes of partial discordance: C2 (partial discordance in favour of the clinical diagnosis- missing injuries in the autopsy reports) and C3 (partial discordance in favor of the necroptic diagnosis- missing injuries in the medical files). Data were analyzed with SPSS version 20.0. Results: We analyzed 194 cases of death due to head injuries. We found a total concordance between the clinical death diagnosis and autopsy diagnosis in 30.4% of cases and at least one discrepancy in 69.6% of cases. Increasing the duration of hospitalization directly correlates with the amount of the imaging investigations and these in turn correlates with an increased rate of diagnosis concordance. Among the patients with stage 3 coma who associated a spinal cord injury, we found a partial diagnosis discordance in 50% of cases and a total discordance in 50% of cases, possibly due to the need for conducting emergency imaging investigation and the need for surgical treatment. In cases with partial and total discordant diagnosis, at least one lesion was omitted in 45.1% of the cases. The most commonly omitted injuries in C2 cases were subdural hematoma, intracerebral hematoma and ventricular hemorrhage (21.6%). In C3 cases the most frequently omitted injuries were subarachnoidian hemorrhage and skull base fractures (17.9%). Conclusions: The clinical cause of death is not always concordant with the autopsy diagnosis. Autopsy may identify the inconsistencies in diagnosis, the injuries frequently skipped and the factors favoring the discordance rate between the clinical death diagnosis and the autopsy diagnosis, making it a valuable tool for improving the clinical care of the patients with head trauma.
First episode of consciousness loss: setting new standards in acute care management
Authors: Cuciureanu Dan Iulian , Nita Antonia , Constantinescu Victor , Cuciureanu Tudor 
Published: December 2017

Abstract
There is a high prevalence of patients addressed to the emergency department presenting a first episode of consciousness loss. The high prevalence of patients admitted to the emergency departments (ED) with a first episode of consciousness loss (ECL) is well established. Although there are studies assessing acute management in these patients, there is still need for more data on clinical and paraclinical characteristics which may prompt early etiological diagnosis, especially in countries where integrated medical procedures are lacking and access to specialized medical care is still limited. Sudden death syndrome, early cerebral morphological changes emerging in chronic epilepsy is the main motivation for an early diagnosis of epilepsy. The aim of our study was to evaluate demographic, clinical and paraclinical data in adult patients referred to our emergency hospital presenting a first episode of consciousness loss, in order to avoid misdiagnosis (with personal and social high impact) and unnecessary anti-epileptic treatment versus underestimation of epilepsy diagnosis. Conclusion: There is a clear need to improve multidisciplinary circuits in patients with a first episode of consciousness loss at a local level, in order to promote accurate and prompt diagnosis. We consider necessary to build a unitary online platform in order to establish an early and complete diagnosis.
