Experimental Investigations of Concrete Filled Battened Steel Columns of Different Slenderness
Authors: Siennicki M.
Published: December 2019

The study investigates the axial load behaviour of concrete filled battened steel columns not covered by the design standards. A series of full scale tests on two I-sections connected together with intermediate batten plates and filled with concrete were carried out. The main parameters varied in the tests are length of the members and strength of the concrete filling. One bare steel member was also tested and results were compared with those filled with concrete. The tests results were illustrated by load-strain curves. The main objectives of these tests were twofold: first, to describe behaviour of new steel-concrete columns and second, to analyze the influence of slenderness on load-carrying capacity.

Authors: Woliński Sz. , Pytlowany T.
Published: December 2019

The paper presents the method of simplified parametric analysis of the sensitivity of a pre-tensioned concrete beam. The presented approach is based on the DOE (design of experiments) data collection which is simulation technique allowing for identification of variables deciding about the effectiveness and costs of designed structures. Additionally, application of the hyper-surface of the construction response allows designers to the development of multi-dimensional trade-off graphs to facilitate, the assessment of the scope of changes in random state variables permitted due to the adequate criteria and selection of their values close to optimum. Design basics, procedures and results of the presented considerations of sensitivity assessment and reliability of the structure has been shown on the example of a pre-stressed concrete beam designed in accordance with the requirements and procedures of Eurocode 2
Minimum Value Approach for Modelling of the Buckling Resistance of Welded I-Section High Strength Steel Columns
Authors: Gajewski M. D. , Giżejowski M. A. , Szczerba R. B.
Published: December 2019

The paper deals with determination of flexural resistance buckling curves for welded I-section steel members made of high strength steel (S 690). In the paper the previously proposed BF analytical model is used for approximation of FEM results obtained using moderately large deformation shell theory and ABAQUS/Standard software. Final formulation of flexural resistance buckling curves is possible through the use of the Merchant-Rankine-Murzewski approach adopted extensively in the authors’ previous papers. For nonlinear optimization, which is needed for analytical model parameters determination, the Wolfram Mathematica package is used. Obtained results for S 690 steel are presented against the results for S 355 steel.
Experimental Tests of Steel Unstiffened Double Side Joints with Flush and Extended End Plate
Authors: Aleksander Kozłowski , Damian Kukla
Published: December 2019

Experimental tests of steel unstiffened double side bolted end-plate joints have been presented. The main aim of the conducted tests was to check the behavior of joints in an accidental situation and possibility of creating secondary mechanism, i.e. catenary action in the scenario of column loss. Two types of end plate joints were tested: flush end-plate (FP) and extended end-plate (EP) with different thickness and different number of bolt rows in each. The tests were carried out on an isolated cross beam-column-beam type system until joint failure. During tests the available moment resistance and rotation capacity of bending joints and also values of tension forces in the beam were determined. The joints with extended end-plate have demonstrated higher bending and rotational capacity than flush end-plate. Significant deformation of column flanges, web and end plate were observed. The fracture of bolts was the failure mode of joints. Obtained results of axial force values in beam exceeded standard requirement what confirmed that the joints with unstiffened web column, flush or extended end-plate possess the ability of development the catenary action.
Mechanical Properties of Aluminium Bracket Strengthening
Authors: Ambroziak A.
Published: December 2019

The aim of the research is laboratory investigation of aluminium brackets employed to fasten lightweight curtain walls to building facilities. Tensile loads perpendicular to end plates (vertical) were applied here. The author focused on the solutions intended to increase the load-carrying capacity of aluminium brackets applying the plain washer form A (DIN 125; ISO 7089), plain washer with an outer diameter about 3d (DIN 9021; ISO 7093) and additional cover plates (straps) in the location of bolt anchoring on the base plate. The aluminium brackets were tested on a steel base and concrete substrate. The flexibility of anchoring strongly affects the increase of the end plate middle point displacement and movable crosshead displacement.
Methods for Dealing with Resistance to Change
Authors: Karaxha Halit
Published: December 2019

The study focuses on effective methods used to address resistance to business change. The aim of the study is to provide information related to methods of handling resistance to change and to present empirical results for each method that is used. In the study, the author uses quantitative methods, and more concretely, the questionnaire technique for data collection. Quantitative research methods that are used include linear regression, cross-tabulations and Pearson Chi-Square test. In this study, 399 businesses in Kosovo were involved. 64 cases of study (businesses) were excluded from the study because these businesses did not use any of the methods presented in the resistance treatment study. The results of the study show that support as a method of resistance treatment is mostly used by the businesses under consideration. The use of these methods has made the changes to be more effective in increasing revenue, providing superior organisational performance and steady market position. This study creates value for businesses, focusing on the importance of using methods for addressing resistance and the success of changes in organisations. However, in reality many initiatives for change fail in achieving their objectives. This fact promotes the interest in recognising those factors that influence the successful implementation of change efforts in organisations.
Accounting Dualism – Particularities and Information Source for Internal and External Users in Organizational Development
Authors: Ciuhureanu Alina
Published: December 2019

Knowing the fact that in the market economy the most important resource is the information and, naturally, since the accounting cannot be substituted for the manager, instead it offers the information necessary for the decision-making processes. The paper highlights, on the basis of bibliographic resources, that a dual accounting representation responds best to all strategic requirements and leads to a better visualization of the entity as a whole, as well as of each structure. Also, in the paper we analyzed, through a selective research, the degree to which the provision of accounting information to various categories of interested users contributes to the development of the entity.
Exemptions Resulting from the International Public Sector Accounting Standards (IPSAS) and European Standards for Intangible Investment, Inventories and Personnel Expenditures in Public Entities
Authors: Enache Corina
Published: December 2019

Simultaneously with the globalization of economies, it was necessary the adoption and implementation of international accounting standards for the public sector also. In 1996 a set of accounting standards for public sector entities was developed, namely International Public Sector Accounting Standards (IPSAS). After 31st July 1998, 32 IPSAS standards, mostly inspired by IASs, centered on model and engagement-based accounting, were issued. IPSAS 1 – Presentation of financial statements relating to the place of intangible assets, inventories and personnel expenses in the content and format of the financial statements is applied to all general purpose financial statements realized under accrual accounting. The IPSAS 12 – Inventory objective is to state the stock accounting treatment. The IPSAS 25 objective – Employee benefits is to state the employee benefits from an accounting perspective.
A Study on the Implementation of Nanotechnology in Enhancing the Environmental Changes
Authors: Thakur Sejal , Chaganti Satya Sandeep
Published: December 2019

The report takes a survey of five crucial areas where nanotechnology is implied. It includes areas of economy through hydrogen, electricity generation with the help of solar cells, fuel additives, batteries, and super capacitors, and insulators. In concern with fuel additives, with the help of nanoparticle, the efficiency of fuel of diesel engines was increased by up to 5 %, which produced about three-million metric tons of CO2 in the UK per year. The study also cautions that this efficiency of fuel additives also led to the release of toxic nanoparticles openly in the environment. Due to small in size, no control could be applied to the restriction of the emission of nanoparticles. Thus, this exhaust gas proves to be harmful to humans. Although a diesel engine, if properly maintained can last up to 300,000-600,000 miles. In comparison with diesel engines, electric engines produce very little efficiency. Solar cells are still a promising area in nanotechnology since they have shown the results of a decrease in the cost while solar cells were produced and have enabled more cell production.

Published: December 2019

The Ironman is one of the most popular triathlon events in the world. Such a race involves a great number of tactical decisions for a healthy finish and best performance. Dehydration is widely postulated to decrease performance and is known as a cause of dropouts in Ironman. Despite the importance of hydration status after an Ironman triathlon, there is a clear lack of review and especially meta-analysis studies on this topic. Therefore, the objective was to systematically review the literature and carry out a meta-analysis investigating the hydration status after an Ironman triathlon. We conducted a systematic review of the literature up to June 2016 that included the following databases: PubMed, SCOPUS, Science Direct and Web of Science. From the initial 995 references, we included 6 studies in the qualitative analysis and in the meta-analysis. All trials had two measures of hydration status after a full Ironman race. Total body water, blood and urine osmolality, urine specific gravity and sodium plasma concentration were considered as hydration markers. Three investigators independently abstracted data on the study design, sample size, participants’ and race characteristics, outcomes, and quantitative data for the meta-analysis. In the pooled analysis, it seems that the Ironman event led to a moderate state of dehydration in comparison to baseline values (SMD 0.494; 95% CI 0.220 to 0.767; p = 0.001). Some evidence of heterogeneity and consistency was also observed: Q = 19.6; I2 = 28.5%; τ2 = 2.39. The results suggest that after the race athletes seem to be hypo-hydrated in comparison to baseline values.

Authors: Clemente Filipe Manuel , Praça Gibson Moreira , Bredt Sarah da Glória Teles , Linden Cornelis M. I. van der , Serra-Olivares Jaime
Published: December 2019

This study compared external load variations between 5 vs 5 and 10 vs 10 sided game formats played under two conditions: (i) a ball possession game with two floaters, and (ii) a regular game with goalkeepers and small goals. Twenty-two professional soccer players participated in this study: four central defenders, four wide defenders, nine central midfielders, three wide forwards, and three strikers. Total distance (TD), running distance (RD), sprinting distance (SD), number of sprints (NS), and player’s training load (PL) were recorded by GPS units. Within-format analyses revealed very likely large increases in TD (20.0%, [9.2; 31.9]; effect size (ES): 1.48, [0.71; 2.25]) and RD (130.9%, [20.2; 343.7]; ES: 1.32, [0.29; 2.35]) during the regular game when compared to the ball possession game in the 5 vs 5 format. In the 10 vs 10 format, large increases in TD (27.9%, [17.7; 39.1]; ES: 3.54, [2.34; 4.74]) and PL (27.4%, [12.6; 44.1]; ES: 2.46, [1.20; 3.72]) were observed in the regular condition when compared to the ball possession condition. Between-formats analyses revealed that, in the 10 vs 10 format, when compared to the 5 vs 5 format, RD was very likely larger (123.5%, [33.7; 273.7]), as was SD (195.8%, [20.5; 626.2]). However, very likely large decreases in PL were observed in the 10 vs 10 format (-19.6%; [-29.4; -8.3]) in the ball possession condition. Unclear differences were revealed based on variations in external load variables between formats in the regular condition. Smaller formats reduce the area available for running and sprinting and, thus, may be more adequate for increasing player’s training load (based on accelerometer data).

Published: December 2019

The aim of the study was: 1. to evaluate the effects of conditioning training on body build and physical fitness in elite mixed martial athletes, 2. to investigate the training load structure and assess body build as well as the physiological profile of mixed martial arts athletes. Fifteen MMA male athletes (body mass: 79.8 ± 3.9 kg; body height: 178.7 ± 7.9 cm; body fat: 13.4 ± 1.6%) were involved in the study. The average training experience of athletes equalled 11 ± 1.1 years. Body composition, upper limb peak anaerobic power and aerobic performance were assessed before and after the preparatory phase. During each evaluation, athletes underwent two stress tests: the Wingate test for the upper limbs (upper limb anaerobic peak power measurement) and the graded exercise test until volitional exhaustion (maximal oxygen uptake measurement and second ventilatory threshold determination). Training means were investigated for the workload type, intensity and exercise metabolism. In the follow-up, body fat mass decreased, while anaerobic peak power and aerobic performance improved. Improvement in the time to obtain and maintain peak power in the upper limbs was noted. Training periodization resulted in advantageous body composition changes and improved physical fitness of the MMA athletes.
Handball Goalkeeper Intuitive Decision-Making: A Naturalistic Case Study
Authors: Menn Marie Le , Bossard Cyril , Travassos Bruno , Duarte Ricardo , Kermarrec Gilles
Published: December 2019

Goalkeepers hold a key position for success in team sports competitions. They perform in dynamical contexts and are highly submitted to time pressure. The purpose of this naturalistic case study, therefore, was to explore how a handball expert goalkeeper deals with the uncertainty of the competition settings to make successful decisions. An individual self-confrontation interview was held with a goalkeeper while he watched duels with potential throwers in an official competition. A mixed method was used combining the first-person and third-person point of view. Verbal data were supplemented by observational data (distance measures between the goalkeeper and the potential thrower) in 83 short accounts of decision-making situations. Qualitative analysis resulted in 419 units of salient features, in three types of processes related to the Recognition-Primed Decision model, and in four micro-decisions. Non-parametrical statistical analysis indicated that there was a significant effect of distances between the potential thrower and the goalkeeper, on the micro-decision categories, but not on the recognition processes. These results provide insights into cognitive contents and processes an expert goalkeeper can use under uncertainty and time pressure. The mixed method furnishes a meaningful description and a subsequent understanding of expert performances in sport.
Analysis of Daily Energy Expenditure of Elite Athletes in Relation to Their Sport, the Measurement Method and Energy Requirement Norms
Authors: Frączek Barbara , Grzelak Andrzej , Klimek Andrzej Tadeusz
Published: December 2019

The purpose of this study was to estimate the daily energy expenditure (DEE) of 30 Polish elite athletes (15 women and 15 men aged 20 to 34 years) representing aerobic-endurance sports and speed-strength sports and to compare the obtained values with energy requirement norms recommended for athletes. Participants’ DEE was measured for seven days using a chronometric-tabular method and a kinematic method. The kinematic method provided significantly lower values of DEE, by 25%. Mean DEEs obtained for female aerobic-endurance and speed-strength athletes were 3042.6 ± 389 and 3255.7 ± 359 kcal/24h (a chronometric-tabular method) and 2230.9 ± 209 and 2346.3 ± 355 (the kinematic method), respectively. The differences between the two groups were not statistically significant (p > 0.05). Male athletes’ mean DEEs were significantly higher (p < 0.05): 3778.0 ± 657 and 4036.7 ± 532 kcal/24h (a chronometric-tabular method) for aerobic-endurance athletes and 2983.3 ± 545 and 2970.4 ± 345 (the kinematic analysis) for speed-strength athletes. As in the case of female athletes, the differences were not significant (p > 0.05). While no evidence was found that the type of sport alone could cause significant differences in the overall mean DEE between aerobic endurance athletes and speed-strength athletes, athletes’ sex significantly differentiated women from men in that respect (the latter’s DEE was significantly greater). Such differences were not noted, though, when athletes’ relative DEE (adjusted for body mass and body composition) were compared. The study revealed that the actual energy requirements of individual athletes can vary in a wide range and that they can be different from recommended energy intake.

Published: December 2019

The objective of the study was to characterize immunological responses to a Brazilian Jiu-Jitsu high-intensity interval training session. Neuromuscular function, blood, and salivary samples were obtained after a Brazilian Jiu-Jitsu high-intensity interval training session. Saliva and blood samples were collected at Pre- (before the warm-up) and immediately Post-training. Neuromuscular function was evaluated by lower body muscle testing. The horizontal countermovement jump was performed at Pre (after the warm-up) and immediately Post blood and saliva collection, and approximately 5 minutes Post-training. The horizontal countermovement jump performance did not present any significant changes Post-training, while blood leukocytes, urea, IgA and salivary alpha-amylase showed a significant increase. Salivary alpha-amylase activity increased more than six times immediately Post compared to Pre-training. Saliva volume, secretion rate, and uric acid were not significantly different between Pre and Post condition. A Brazilian Jiu-Jitsu high-intensity interval training session elicited an increase in the blood cells responsible for antibody production and muscle damage adaptation after exercise. On the other hand, neuromuscular performance was not significantly affected Post-training, suggesting that immunological and performance responses were not necessarily associated.

Authors: Amado Diana , Maestre Miryam , Montero-Carretero Carlos , Sánchez-Miguel Pedro Antonio , Cervelló Eduardo
Published: December 2019

The current study aimed to evaluate the determinant factors of athletes´ internal positive self-talk that might lead to decreased anxiety and increased performance. The sample consisted of 191 male and female athletes ranging in age from 14 to 35 years old. They played soccer, volleyball and basketball and they were cadets (43%), juniors (29.6 %) and adults (27.4%). Results showed that satisfaction of the basic psychological needs was the strongest predictor of positive self-talk or positive thoughts during competition. Specifically, perception of autonomy was the strongest predictor, because it positively predicted concentration, control of anxiety and instructions, followed by perception of competence, which positively predicted confidence. Finally, team sports coaches should promote perception of autonomy and competence in their athletes, with the aim of enhancing more positive self-talk in competition, which may promote a better performance.
Populist Party Leaders in Belgium: an Analysis of VB AND PVDA-PTB
Authors: Wauters Bram , Pittoors Gilles
Published: December 2019

This article scrutinizes the position and the role of the party leader in two populist parties in Belgium: Vlaams Belang (VB) and Partij van de Arbeid — Parti du Travail de Belgique (PVDA-PTB). Following Mudde’s definition, populism is understood as a people-centered and anti-elitist ideology. The article argues that, if one accepts the notion that parties will organize themselves in line with their ideological beliefs, then one should expect populist parties to exhibit three main characteristics: leaders are directly elected by the party members, they have extensive powers with only minimal intra-party institutional checks, and they feature strongly in electoral campaigns. Applying this argument to the two Belgian populist parties, the article finds only limited evidence for the argument that populist parties mirror their ideology in the role and position of their party leader.
The AfD as a ‚Leaderless’ Right-Wing Populist Party. How the Leadership-Structure Dilemma Left an Imprint on the Party’s Leadership
Authors: Zons Gregor , Halstenbach Anna
Published: December 2019

Despite its right-wing populist character, the Alternative for Germany (AfD) shows no signs of a strong party leadership. We ascribe this state of the party leadership to the AfD’s institutionalization as a new party and show how organizational features interact with the skill set and goals of the party leaders. At the party level, we, firstly, outline the organizational change at the top of the party and the party leader selection rules. Secondly, we depict leadership turnover and competitiveness. At the leader level, we investigate the failure of Bernd Lucke, the key founder and one of the initial party leaders, as a manifestation of the leadership-structure dilemma of new parties. Embedded in a leadership team and faced with a growing extra-parliamentary party structure, Lucke tried to secure his initial autonomy and position of power by an attempt to become the sole party leader. His subsequent exit from the AfD laid bare the fact that he was not able to manage the challenges of the organizational consolidation phase, in which a new party needs a coordinator and consensus-builder. The AfD itself has proven its organizational autonomy from its initial leaders and its distaste for a strong and centralized party leadership. The barriers for the latter remain in place while, at the same time, the party institutionalization is still on-going, especially regarding its place in the German party competition.
When Charisma is no Longer Enough. Insights on Populist Parties’ Leadership from the (Northern) League
Authors: Sandri Giulia , Seddone Antonella , Venturino Fulvio
Published: December 2019

Several scholars of populism have pointed out that populist parties rely very oft en on so-called charismatic leadership (Canovan, 1981; McDonnell, 2015). While the rise of populist parties in Europe in the last decade is quite evident and well-studied, what remains understudied is how this phenomenon interacts with other transformations that are currently shaping parties and party systems in European democracies. In particular, what is the interplay between the rise of populism, political leadership and personalization of politics? This link between populism and leadership could be understood in the light of the change occurring within party organizations, and internal party democratization in particular (Musella, 2015; Pogunkte and Webb, 2007; Karvonen, 2010; Scarrow et al. 2017). Following these studies underlining a close relationship between populism, leadership and inclusive leadership selection methods, in this paper we aim at empirically exploring how the personalization and democratization of organizational patterns affect the role of the leader in populist parties. To what extent does the use of inclusive selection methods of party leaders within populist parties affect the scope of their organizational power and strengthens the party’s personalization patterns? To explore this research question, we focus on a case study, the Lega Nord (LN) in Italy as an empirical illustration and we rely on original survey data, on aggregated electoral data as well as on primary and secondary data on party organizational rules.
Twins In Power. Jarosław Kaczyński and Lech Kaczyński as Leaders of Law and Justice
Authors: Hartliński Maciej
Published: December 2019

Rarely do twins play active and significant roles in politics. Yet in 2006 President of the Republic of Poland, Lech Kaczyński, designated his twin brother Jarosław to be prime minister. The aim of the current publication is to analyse the political activity of Lech and Jarosław Kaczyński in the context of the founding of PiS and its functioning. Their position inside the party is undisputed. Moreover, as there is no opposition inside the party and Jarosław Kaczyński achieves spectacular electoral results, his legitimisation as autonomous leader of the party is strengthened even further.
