Authors: Wesołowski Mariusz , Pietruszewski Paweł , Kowalewska Agata 
Published: January 2020

Abstract
The natural airport pavement is formed by an adequate preparation of the ground. It should be adapted or constructed in such a way as to minimize the risk to aircraft in the event of an airplane running off the runway. Research indicates that a significant part of natural airport surfaces in Poland do not meet the requirements for load capacity and require reinforcement. The article presents methodology for reinforcing soils, describes the methods of testing the capacity of natural airport pavements and presents the results of research on the natural airport pavement, in reference to the construction with a cellular geosynthetic (geocell).
Analysis of Possibility of Phase Shift Model Usage for Identification of Gas Leakage from Pipeline with Corrective Elements
Authors: Grądzki Rafał , Golak Karol , Lindstedt Paweł 
Published: January 2020

Abstract
Proposed method of leakage identification uses a parametric model in the form of signals phase shift (φ). Signals from the test stand will be used: r1, r2 - signals from the corrective elements connected to the tested pipeline, pressure signals x, mass flow y and simulated mass flow yw. For these signals, their auto and cross power spectral densities are determined: Sxx, Syy, Srr, Sxy, Sxr, Syr, which are the basis to determine spectral transfer functions described as the relations between these signals and next the phase shifts (φ). Thanks that, we get a large set of transfer functions, hence a large set of phase shifts between the measured.

Published: January 2020

Abstract
The article presents the impact of welding imperfections on the strength and microhardness of AW 5754 aluminium alloy welded joints executed with the TIG method. It presents the results of tomographic tests of welds. The results of strength and microhardness tests involving welds executed under various welding process parameters were shown. The impact of welding imperfections on the strength and microhardness of a welded joint was analysed. Based on analysing the relations between the r Pearson coefficient values and multiple correlation, significant relationships between strength, hardness and weld defects were evidenced. Furthermore, a very strong relation between the welding process parameters, welding imperfections, and weld strength and microhardness was shown.
Sliding Wear Examination of New Protecting Coatings on Railway Buffer Heads
Authors: Gamon Wojciech 
Published: January 2020

Abstract
The paper presents the results of tests of sliding wear of bronze coatings made on the surface of specimen made of S355J2 steel by laser cladding method. On the basis of the conducted tests it was found that the wear of the specimens with CuAl9Fe3 bronze coating is characterized by average values which are close to lubricated specimens. In addition, the registration of friction coefficients of particular couples showed very similar characteristics of these two friction couples and friction coefficient values at a very similar level. This allows to assume that the currently used method of protecting railway buffer heads, consisting of periodically covering their surface with lubricant, can be replaced with another, more durable, based on bronze protection coatings.

To meet the requirements, manufacturers install particulate filters in the exhaust systems of most new engines. The article presents the results of vehicle testing with this solution during the drive carried out in accordance with the RDE procedure. The measurement results, after taking into account the Conformity Factor in relation to the approval limits, confirmed the efficiency of aftertreatment system in terms of both gas and solid components.
Is the Greek debt sustainable? Analyzing three different scenarios for the forthcoming period 2018–2022
Authors: Economou Emmanouil M.L. , Kyriazis Nicholas 
Published: January 2020

Abstract
In this paper, we attempt to estimate the development of the Greek public debt for the period 2018–2022. In order to achieve this, we analyze three different fiscal scenarios that are based on the official data available, together with our estimations that are based on a specific conceptual framework that we develop. The three scenarios are based on a different mixture of Gross domestic product (GDP) growth rates and budgetary surpluses of GDP. The analysis concludes that the numerical outcome is almost the same in all three case scenarios. However, the third scenario is the best since it leads to higher growth, GDP, and less austerity measures, and thus making public debt sustainable in the long run. The third scenario also provides the best combination of the trade-off between austerity and growth. We conclude by discussing some policy measures.
Colour in Online Advertising: Going for Trust, Which Blue is a Must?
Authors: Broeder Peter , Snijder Hessel 
Published: January 2020

Abstract
In an online environment the customer relies heavily on cues that indicate that an electronic vendor (e-vendor), can be trusted (especially in comparison with an offline shopping environment). Several studies investigated the factors that reduce mistrust in an online environment. However, little is known about the effects of colour on the process of establishing trust between e-vendor and consumer, and purchase intention. The current body of studies on the effects of, specifically, the colour blue on trust in an online environment also show contrasting results. Further, the literature review revealed that (value) variations of colours have different effects on human behaviour, or perception. It was also argued that the effect of blue on trust and behaviour would be greater for people from cultures that are generally more risk averse. The aim of the present study, therefore, was to investigate the effect of two different values of blue (i.e. lighter and darker valued) on trust and the intention to book an accommodation, differentiated by culture. In an online experiment 91 Chinese and 125 Dutch respondents (average age 27 years) were presented with an accommodation offer displayed within either a predominantly darker, or lighter valued blue environment. The results showed an indirect (mediating) effect of trust on the relationship between the predominantly darker coloured blue environment and booking intention. There was no evidence for the hypothesized moderating effect of culture. To conclude, this study contributes to a better understanding of the effects of (value) variations of colour in an online environment on human behaviour, and perception. The use of dark blue colour schemes in an online environment can be recommended to e-vendors. Especially in online environments in which the customer is more involved (e.g. financially) or vulnerable in the (purchasing) process, and thus more cues are needed to win a visitor’s trust.
It’s a Relationship Business! An Embedded Network’s Internationalization as a Process of Sense-Giving and Sensemaking: The Case of Japan, Shipping Industry
Authors: Járfás Zsuzsanna 
Published: January 2020

Abstract
This is an exploratory study, it seeks to understand internationalization of a business group as a process of sense-making on the individual level. The focus of the enquiry is a Japanese shipping group, bulk cargo segment and seeks to answer the question how a network’s administrative heritage enables and/or inhibits the performance of relationship management processes in the context of multiple embeddedness and internationalization. The study finds, that the industry at large and the Japanese Business Group (JBG) as institutions act as enablers for the effective management of existing relationships worldwide by delegating action to the field through standardized processes and shared understandings. As for identifying and developing new relational opportunities, JBG as an institution inhibits coordination and sensemaking capabilities by its strict vertical power hierarchy and a concentration of authority and resources in headquarters.
The Integration of Behavioural Change Models in Social Marketing Programs in Public Health
Authors: Savciuc Oxana , Timotin Alina 
Published: January 2020

Abstract
The aim of the paper is to provide a conceptual theoretical framework of the integration of the theories and models of behavioural change in the marketing mix of the social marketing programs applied in public health. A second purpose is to highlight the benefits of social marketing over alternative techniques used in programs that are designed to influence health behaviour. The research is a conceptual one, that uses both theoretical (through examination of theories and concepts) and applied approaches (through examination of particular cases and examples). In the specialized literature there are presented multiple models/theories of behavioural change, but their specific application in the marketing mix of the social marketing programs is insufficiently described. The need to use these theories in the public health sector arises from the extended application of social marketing in this field and the specificity of the domain. Eight main theories of behaviour change were studied according to their purpose, variables (possibility of segmentation) and limits. Accordingly, the study presents how these theories can be integrated in the process of social marketing implementation in defining the marketing mix strategy. In this regard, it is important to underline the advantages of using social marketing (in contrast to alternative techniques like PRECEDE/PROCEED or the ecological models), namely: it is based on consumer orientation, uses marketing research, creates attractive exchanges, considers competition, uses the marketing mix, ensures management of the processes. In addition, some elements of the alternative techniques can be taken over in the application of social marketing. Social marketing is a very useful practical tool, but it needs a well-grounded theoretical support in order to gain ground in front of other similar theories. This paper tends to enhance the theoretical tools available for researchers and practitioners.
Correlation of Recruitment and Selection of Human Resources and the Performance of Small and Medium Enterprises
Authors: Klepić Iva 
Published: January 2020

Abstract
Human resources are the most significant resource of a company; this is especially true for small and medium enterprises (SMEs) in which they create the company’s competitive advantage because of their uniqueness. Human resources manage other resources and are responsible for the efficiency and success of the organization. The main goal of this research is to determine whether and to what extent the recruitment and selection of human resources are in correlation with the performance of SMEs. The research was conducted in SMEs in the Herzegovina Region in the Federation of Bosnia and Herzegovina in April 2019. An original questionnaire was created for the survey, within which top managers views on recruitment and selection of human resources were collected as well as the four-perspective performance of the business based on the Balanced Scorecard model. SPSS 20.0 was used for data analysis. Descriptive measurements used for data analysis include mean, standard deviation, and mode. The Kolmogorov-Smirnov test was used to test distribution normality. To test the correlation of variables and to determine the significance of differences, the Pearson correlation coefficient and t-test for independent samples were used. The level of significance was set to p = 0.05. The research results showed the correlation between the studied variables and the correlation of recruitment and selection of human resources and the performance of SMEs viewed from all four perspectives. A limitation of the research is the sample size and the sampling method. The results can be applied in the human resource management of SMEs.
What You Post is What You Get: The Mediator Role of Reached Individuals in the Causal Relationship among Posted Content Types and Follower Counts on Facebook
Authors: Poecze Flora 
Published: January 2020

Abstract
This paper discusses the causal relationships among posted content types, the number of reached individuals and follower counts of a Facebook brand page by investigating the communication forms of a Hungarian Twitch.tv live streamer. The Kolmogorov-Smirnov test for the analyses’ distributional properties is followed by the Kruskal-Wallis H test, which determines significant differences in content types in terms of their total reach, reaction, comment and share counts. The Kendall’s tau-b tests are performed for the examination of interrelationships among the retrieved Facebook metrics. Furthermore, mediation analysis is conducted, wherein the antecedent role is taken by post type, the follower count appears as a consequent variable and the total reach count takes the mediator role in the proposed model. The results of the analysis conclude that the analysed Facebook metrics display statistically significant, strong and positive correlations with one another; additionally, post type has a strong, significant and direct influence on reached individuals and although they do not show a significant, direct influence on follower count, they display a significant, total effect on it. The paper thereby contributes to the existing online brand personality and gaming research, offering value to the research domain of online marketing and communication as well.
Unions and Decisionistic-Restricted Involvement in the CSR Debate – An Explanation to a Cooperative Approach
Authors: Zemla Nataniel 
Published: January 2020

Abstract
Corporate social responsibility (CSR) implies the responsibility of companies for sustainable management in economic, ecological and social terms. The majority of CSR works in science and research were written primarily with the focus on ethics (moral vs. market economy), bearer of responsibility (state vs. companies) and management (e.g. best practice, manuals). This article comes from the perspective of a stakeholder group that is constantly mentioned but receive insufficient attention: unions. Research indicated early on that unions leaned back in the European CSR-debate since its beginning 2001. Based on the case of German unions, the author will analyse their motivation by studying their statements. The systematic literature review provides the basis for his qualitative content analysis of reasonable motives. The results show the unions encountering a complex environment with diverse interests, in which it is difficult to position themselves. Furthermore CSR requirements placed on companies were considered, by economy, to be set very high. Although CSR is not driven by legal regulations, it unfolds quasi-binding rules. For those reasons, it is not surprising that unions were sceptical and restrictive. With its analysis of a defensive CSR strategy, the study contributes to progress in the field of engagement in international debates. The author deals in a theoretical-conceptual way with the existing research results in this field, invalidates them and presents his own attempt with explanation. His explanatory approach extends the existing explanatory patterns by a new perspective for the problem described.
Structural Assessment of the Hull Response of an FPSO Unit to Dropped Objects: A Case Study
Authors: Ozguc Ozgur 
Published: January 2020

Abstract
Offshore structures are exposed to the risk of damage caused by various types of extreme and accidental events, such as fire, explosion, collision, and dropped objects. These events cause structural damage in the impact area, including yielding of materials, local buckling, and in some cases local failure and penetration. The structural response of an FPSO hull subjected to events involving dropped objects is investigated in this study, and non-linear finite element analyses are carried out using an explicit dynamic code written LS-DYNA software. The scenarios involving dropped objects are based on the impact from the fall of a container and rigid mechanical equipment. Impact analyses of the dropped objects demonstrated that even though some structural members were permanently deformed by drop loads, no failure took place in accordance with the plastic strain criteria, as per NORSOK standards. The findings and insights derived from the present study may be informative in the safe design of floating offshore structures.
Improvements to a Fire Safety Management System
Authors: Zeńczak Wojciech , Krystosik-Gromadzińska Agata 
Published: January 2020

Abstract
The statistics invariably show that most onboard fires originate in the engine room. In hazardous conditions, fires can spread to other rooms of the ship and cause the loss of human life, and can cause the ship to be out of service or lost completely. To prevent these serious consequences, the engine room crew should be aware of hazards and ways to prevent them. It is also advisable to support their routine activities and actions in critical situations with an appropriate management system.
For this reason, a survey was conducted at the beginning of 2019 of engine room crew members employed by a European shipowner, as a contribution to an analysis of fire safety management. Based on the results of the survey, some of the elements of the fire safety management system of the ship engine room are described. A properly constructed system that is understandable and accepted by the crew is one of the most important factors in increasing fire safety on a ship. Familiarisation with adequate procedures can significantly contribute to the successful prevention of accidents. This paper also proposes a checklist based on suggestions by the crew, which may be helpful in onboard fire prevention.

Published: January 2020

Abstract
The design of a floating, innovative device for river water aeration and conversion of mechanical energy to electrical energy required the analysis of a number of geometrical and dynamic features. Such an analysis may be carried out on the basis of existing methods of numerical fluid mechanics. Models of pressures, forces and torques characteristic for the conversion of watercourse energy were developed for two basic concepts of innovation. These pressures, forces and torques were calculated, designed, and experimentally determined for the variable geometric form and dimensions of the designed working elements of the innovative roller-blade turbine rotor.
Comparative Studies of the Seatings of Propulsion Plants and Auxiliary Machinery on Chocks Made of Metal and Cast of Resin Part I. Mounting on Steel Chocks
Authors: Grudziński Paweł , Konowalski Konrad 
Published: January 2020

Abstract
This paper presents a description and the results of experimental studies of the deformation, friction and structural damping occurring in foundation bolted joints of propulsion plant components and auxiliary machinery that is rigidly mounted on sea-going ships. The rigid mounting of these devices to the ships’ structural foundations can be implemented in a traditional way, i.e. on chocks made of metal (usually of steel), or in a modern way, i.e. on chocks cast of resin, specially designed for this purpose. The main goal of this study is to perform a comparative analysis of these two solutions and to give a scientific explanation for why chocks cast of resin perform better in machinery seatings than the steel chocks traditionally used for this purpose. The paper consists of two parts. Part I presents the details of the rigid mountings of machinery to the foundations, and contains the results of experimental studies performed on a model of a foundation bolted joint with a traditional steel chock. Part II contains the results of similar studies carried out for a model of a bolted joint with a modern chock cast of resin. Next, a comparative analysis and evaluation of the results obtained for both investigated bolted joints was carried out, and conclusions were formulated to highlight important aspects of the problem from the point of view of science and engineering practice.
Effects of Water Intake Layout along the Wharf Shoreline on Ships
Authors: Kong Xian-wei , Ding Lei , Liu Hai-cheng , Qu Jing , Li Xiao-song 
Published: January 2020

Abstract
The construction of a water intake along the wharf shoreline can realise the intensive and comprehensive utilisation of the shoreline. However, since the water intake will increase the lateral flow at the wharf and also the hydrodynamic forces on ships, it will bring risks to ships mooring and leaving. The effects of the water intake on ships are studied using a physical model, numerical model and standard formulas. The results show that it leads to an increase of the hydrodynamic forces acting on the ship when the standard formulas are used to calculate the forces without considering the water level difference between the two sides of the ship. The results of the physical model are closer to the real situation. Measures that can effectively reduce the influence of the water intake on ships are proposed by increasing the distance between the wharf front and the front of the water intake as well as the depth of the water inlet windows.
Evolutionary Perspectives on Unbelief: An Introduction from the Editor
Authors: Messick Kyle J. 
Published: January 2020

Abstract
The scientific study of atheism and unbelief is at a pivotal turning point: past research is being evaluated, and new directions for research are being paved. Organizations are being formed with an exclusive focus on unbelief research, and large grants are funding the topic in ways that historically have never happened before. This article serves as an introduction to the state of the literature and study of evolutionary perspectives towards unbelief, which incorporates cognitive, adaptive, and biological contributors. This article serves to contextualize the subsequent articles, which all have distinct perspectives on the evolutionary factors that contribute towards unbelief.
Biomedical Moral Enhancement for Human Space Missions
Authors: Szocik Konrad 
Published: January 2020

Abstract
Biomedical moral enhancement is an idea which states that human moral intuitions and patterns may be artificially improved by biomedical means. The rationale which lies behind moral bioenhancement is rooted in the idea that humans – in a moral and behavioral sense – are not evolutionally adapted to current ecological challenges. This idea is discussed in the paper in relation to human space missions to Mars and beyond. Because the space environment is a hazardous environment, there are some reasons to consider the idea of moral bioenhancement for the purposes of mission success and the safety of astronauts/space settlers. This paper discusses that idea in the context of a broader discussion on moral enhancement, moral bioenhancement related to earthly issues, and the idea of moral progress.
