Authors: Sepehrnia Nasrollah , Woche Susanne K. , Goebel Marc-O. , Bachmann Jörg 
Published: November 2020

Abstract
Microinfiltrometers to assess soil water repellency (SWR) are limited to small tension ranges and have different technical setups, hindering a comparison between results from different laboratories. Hence, a microinfiltrometer which considers various aspects like extent and persistence of SWR is needed. The technical update suggested here uses glass tubes (e.g., 3 mm inner diameter), a fabric of mesh size 15 µm around the tip to enable good contact between soil surface and tip, ultrapure degassed water, and an evaporation protection for tip and reservoir during long-term infiltration. The adjustment of a continuous range of pressures and tensions (i.e., +0.5 to –40 cm) was done using glass tubes of various lengths connected to the tip. Three soil samples with initial contact angles, CA, of 18°, 62°, and 91° after 25°C treatment were additionally treated at 80°C to increase SWR persistence and CA. The soil particle interface chemical composition was determined by X-ray photoelectron spectroscopy (XPS). The hydrophysical properties evaluated included water and ethanol sorptivity as well as very important aspects of SWR, i.e. water drop penetration time, water repellency cessation time, repellency index, and modified repellency index. The results derived from the technically modified microinfiltrometer setup showed consistent differences between initial wettability and the water repellency cessation time as a parameter describing the development of SWR with time. The interface O/C ratio as derived from XPS data was negatively correlated with CA (p <0.05), thus proving the close relationship between interface chemistry and wettability. Our findings illustrated a strong positive correlation (R
2 = 0.99, p < 0.05) between sorptivity and O/C ratio under –2 cm tension which can be considered as the universal tension for different aspects of SWR.

Authors: Rybaczewska Maria , Chesire Betty Jebet , Sparks Leigh 
Published: November 2020

Abstract

Objective: The increasing influence of YouTube vloggers on consumer purchase behaviour and the specificity of the vloggers _ viewers/subscribers relationship are under-researched. Addressing this gap in knowledge, this paper explores the role of vloggers as brand influencers on consumer (their viewers) purchase behaviour. It aims to investigate the interaction between vloggers and viewers/subscribers in terms of brand awareness and consumers’ purchase behaviour.

Methodology: A mixed-method approach (often connected with netnography) incorporated non-participant observation of vloggers’ activities and vloggers-viewers interactions within selected popular vlogs, supported by an online survey with both vloggers and viewers.

Findings: We have observed specific brand endorsements and experiences, depending on the vloggers’ context, leading to both positive and negative feedback. This interaction and the consistently positive perception of reasons behind the vloggers’ choice of the endorsed brands underpin the credibility of the vloggers – viewers/subscribers relationship.

Value added: Our results show not only the significance of vloggers as brand influencers, providing their audiences information perceived as trustworthy and convincing in terms of purchase recommendations but also explore the factors affecting this process.

Recommendations: This research directed our attention into the viewer-viewer interaction on the vlogs platforms. It is a very dynamic and challenging (difficult to control) part of vlog marketing activities (including various eWOM aspects) which can be very influential in the analysed context and stays a task for the future research.
Legendre-Chebyshev pseudo-spectral method for the diffusion equation with non-classical boundary conditions
Authors: Chattouh Abdeldjalil , Saoudi Khaled 
Published: November 2020

Abstract
The present paper is devoted to the numerical approximation for the diffusion equation subject to non-local boundary conditions. For the space discretization, we apply the Legendre-Chebyshev pseudospectral method, so that, the problem under consideration is reduced to a system of ODEs which can be solved by the second order Crank-Nicolson schema. Optimal error estimates for the semi-discrete scheme are derived in L
2-norm. Numerical tests are included to demonstrate the effectiveness of the proposed method.
The influence of self-doping of stibnite ore with impurities on the preparation, heat capacity, magnetic and transport properties of tetrahedrite Cu12Sb4S13

Published: November 2020

Abstract
Stibnite mineral (mainly Sb2S3) has been employed for the synthesis of tetrahedrite Cu12Sb4S13 bulk material by spark plasma sintering. High purity Cu12Sb4S13 can be quickly obtained by two sintering procedures at temperatures from the range of 420 °C to 440 °C for 1 h. Appropriate reduction of Cu content (Cu12+xSb4S13, x ⩽ –0.05) or CuS content (Cu12−ySb4S13−y, y = 0.1 or 0.3) was beneficial to fabricate Cu12Sb4S13. The secondary resintering improved the purity of Cu12Sb4S13 material. The first-order magnetic phase transformation with magnetic hysteresis effect was confirmed by the behavior of susceptibility, heat capacity and resistivity. The magnetization showed a linear increase with increasing field (up to 7 T) and non-saturation behavior was observed. The impurities in stibnite mineral Sb2S3 had a weak influence on the transformation temperature but affected the low-temperature magnetization value (~0.15, close to natural tetrahedrite). Similar transformation was observed by the analysis of heat capacity. The properties such as electrical resistivity, Seebeck coefficient and thermal conductivity were also measured for Cu11:9Sb4S13 and Cu11:9Sb4S12:9. The maximum figure of merit ZT of Cu11:9Sb4S12:9 was 0.22 at 367 K.

Diversification of Factors Influencing Qualitative Evaluation of a Historical and Cultural Destination
Authors: Zhang Juan 
Published: November 2020

Abstract

Introduction. Perceived quality combined with tourist motivation, tourist experience and other variables were identified as important antecedents of tourist satisfaction and destination loyalty. However, few studies have examined factors influencing a tourist’s perception of the service quality in a destination, especially in specific destinations. The main purpose of this study was to investigate whether tourist motivation and tourist experience influence how tourists perceive quality and to analyse complex relationships between the constructs of perceived quality, tourist experience, tourist motivation and tourist satisfaction in the context of historical and cultural destinations.

Material and methods. A survey of 1,389 tourists who visited an ancient town in the center part of China served as the basis for analysis. Structural equation modelling was employed to test the proposed hypotheses.

Results. The empirical results showed that tourist motivation and tourist experience exerted a significant positive influence on perceived quality. These three variables had a simultaneous significant positive impact on tourist satisfaction. The results also revealed the mediating effects of tourist experience and perceived quality in the proposed model.

Conclusions. The article verified a model regarding the relationships between tourist motivation, tourist experience, perceived quality and tourist satisfaction. According to the results, a historical and cultural destination could improve a tourist’s perceived quality and satisfaction by enhancing tourist experience and providing tourist stimuli.
Determination of Additional Tension in Towed Streamer Cable Triggered by Collision with Underwater Moving Object
Authors: Blintsov Vladimir S. , Trunin Konstantin S. , Tarełko Wiesław 
Published: November 2020

Abstract
The paper deals with issues connected with the behaviour of a streamer cable towed by a survey seismic vessel when the cable undergoes a strike triggered by collision with an underwater moving object. The consequences of such collisions may be both threat to the life of marine animals or damage to underwater units and large economic losses suffered by vessel owners. The risk of such collisions has increased over the last years as a result of increased offshore seismic survey operations. Therefore, a towed streamer should be very robust. To assure its robustness, we should know the deformation mechanism of a single streamer cable. This in turn requires the development of an appropriate mathematical model of such a phenomenon.
In particular, the paper presents the characteristics of seismic survey vessels and streamers; an analysis of collisions that have occurred in the past; a statement of the problem, and a computer-aided system supporting simulation of the cable behaviour. To obtain all the necessary design parameters regarding the deformation mechanism of a streamer cable, we set up a dedicated computer-aided system that supports their calculation.
Validation Process for Computational Model of Full-Scale Segment for Design of Composite Footbridge
Authors: Ferenc Tomasz , Mikulski Tomasz 
Published: November 2020

Abstract
Experimental tests and numerical simulations of a full-scale segment of a foot and cycle bridge made of polymer composites are presented in the paper. The analysed structure is made of sandwich panels, which consist of glass fibre reinforced polymer (GFRP) multi-layered laminate faces and a PET foam (obtained from recycling) core. The dimensions of the segment cross-section are the same as for the target footbridge; however, span length was reduced to 3 m.
The experimental tests were conducted in a laboratory of the Faculty of Ocean Engineering and Ship Technology at Gdansk University of Technology. A single vertical force was generated by a hydraulic cylinder and was applied to the platform of the structure. The experimental tests were supported by numerical analyses performed in Femap with NX Nastran software by means of the finite element method (FEM). Results obtained in the computational model were compared with results from experiments. Thus, the numerical model was validated and the obtained conclusions were used in the next step of the design process of a composite footbridge with a span length of 14.5 m.
Rural Development in Romania – A Few Considerations
Authors: Paul Lucian 
Published: November 2020

Abstract
The ‘Agenda 2000’ introduces the Rural Development Policy, as part of the Common Agricultural Policy (CAP), as a complex policy that can ensure a stable income and a reasonable standard of living for the rural population. Rural development is a major CAP objective since over 50% of the population lives in rural areas and accounts for 80% of E.U. Territories. As a concept, the ‘rural area’ is defined both at a national and European level following specific criteria; however, these criteria differ from one country to another. A complete definition can be found in the European Charter of Rural Areas. Between 2014-2020, the development of rural areas in Romania is supported by the National Rural Development Program. It provides non-reimbursable funds from the European Union and funding from the Government of Romania. Convergence with the Europe 2020 Strategy is ensured through the Partnership Agreement with the European Union, which covers a number of challenges and thematic objectives. In order to achieve them, well-founded investment programs are needed. These programs must have a direct impact on increasing the living standards of the population residing within rural areas. Over 19 billion euros were allocated to Romania for the 2014-2020 period; these funds were used for agricultural policy and rural development. The total budget of the NRDP (2014-2020) is 9.4 billion euros, of which 1.3 billion euros comes from national funding. We believe the achievements recorded in rural areas, up to 2020, are modest and do not reflect the proposed objectives. Thus, projects were drawn up at national and local levels seldom support rural development and do not reflect development needs; sadly, these projects are often drawn up without focusing on efficiency.

Published: November 2020

Abstract
Nowadays, with the daily expansion of marketing attractions to create different experiences in the restaurant & fast food industry, unconscious stimuli attracting the major senses might be an effective way to attract the consumers. Understanding these environmental stimuli suggests a correct perception of feeling and perception which is in harmony with consumer behavior. Moreover, knowing these factors can also be essential for marketers and owners and managers who are active in this area to develop strategies to create positive experiences for customers and increase the sales. Therefore, the objective of the present study is to focus on customer experiences and their possible effects on purchase intention of consumers through mediator variables of mental engagement and visual perception. The present study is an applied study in terms of objective and correlational type of descriptive-survey study in terms of data collection. The research population consisted of those people using the services of restaurants and fast food stores of Shiraz. A total of 385 samples were selected by using convenient sampling method. Questionnaire was used as tool to collect the data. The questionnaires were distributed in person and they were collected after being completed by the subjects. Its validity was examined through content validity and its reliability was examined through Cronbach’s alpha. Data were analyzed using structural equation modeling and Smart PLS software. The results of this study showed that customer experiences had a positive and significant effect on mental engagement and visual perception, and these two variables had a positive and significant effect on consumer purchase intention. The indirect effect of customer experiences on consumer purchase intention was also confirmed through the mediator variable of mental engagement and visual perception.
Estimating the Demand for New Destinations for a Regional Airport Based on Its Catchment Area
Authors: Mihai Ţichindelean , Marieta Mihaiu Diana , Alin Opreana , Cosmin Tileaga 
Published: November 2020

Abstract
Estimating accurately demand both at market and company level for specific goods and services can be considered a necessity for every organization. Traditional demand estimation methods may not be relevant for estimating the demand for new destinations to be introduced by a regional airport. The present paper proposes to fill this gap and to develop the demand estimation literature by presenting a novel demand estimation method. Two research objectives are developed in this regard: (1) determining the catchment area of Sibiu International Airport (a regional airport in Romania) for destinations operated by competitor airports and not by Sibiu International Airport and (2) estimating the demand for new destinations based on the identified catchment area.
Digital Transformation of Centru Region – Romania. Needs Assessment
Authors: Claudia Ogrean , Mihaela Herciu 
Published: November 2020

Abstract
Competitiveness represents a never-ending moving target for any institution/entity, no matter the level of analysis (micro - companies /public administrations, mezzo - industries / national regions, or macro - countries / world regions); but its determinants (or key success factors) are changing, as ages go by, asking for continuous watch and strategic flexibility. With digital technology nowadays disrupting (almost) every aspect of human life, while framing a new age - of digitalization being both a source of competitiveness (for the industry leaders - whatever the “industry” might be), and (just) a prerequisite for survival (or doing business) for almost everyone else, the European Commission’s political priority for 2019-2024 “A Europe fit for the digital age” and the EU’s digital strategy aiming for a “digital transformation that will benefit everyone” are of great interest (accentuated by the new pandemic context) for all the EU regions and their institutions/entities. Within this framework, the paper (which is part of a bigger research) aims to perform an overview scan of Centru Region-Romania (mainly by comparison with Romania’s other Development Regions and with EU benchmarks) in order to broadly identify its needs for digital transformation, while setting the backgrounds for a more systematic, focused and applied analysis to follow.
Bleomycin-induced Flagellate Dermatitis: a Case Report
Authors: Tonin Beatrice , Geat Davide , Girolomoni Giampiero 
Published: November 2020

Abstract
Flagellate dermatitis represents a unique cutaneous eruption associated with several causes, including treatment with certain chemotherapeutic agents, ingestion of toxins and rheumatologic conditions like adult-onset Still’s disease and dermatomyositis. We present the case of a 35-year-old woman with stage IIA Hodgkin lymphoma who was treated with the ABVD chemotherapy regimen (doxorubicin, bleomycin, vinblastine and dacarbazine). During the third cycle of chemotherapy, she developed multiple linear erythematous macules and hyperpigmentation in a striking flagellate-like pattern localized on the upper chest, submammary folds, neck and upper part of the back. The lesions resolved completely within three months after the withdrawal of bleomycin. Clinicians should be aware of this distinctive cutaneous toxicity in patients receiving bleomycin combination chemotherapy.
Dermatoscopic Features of Combined nevus – a Case Report
Authors: Stojković-Filipović Jelena , Trifunović Branislav , Bosić Martina 
Published: November 2020

Abstract
Combined nevi (CN), a rare nevus type represent a category of so-called compound tumors. Determined by the presence of two or more different nevus in one biopsy specimen, CN commonly show variable clinical and dermatoscopic features. Therefore, CN could be a diagnostic challenge. We present a 7-year-old Caucasian girl with a pigmented lesion on the arm of no specified duration. Clinical examination showed sharply demarcated pigmented papule. Dermatoscopy revealed a nonchaotic lesion with structureless well defined, minimally eccentric blue area, structureless brown area and brown clods in a symmetric fashion, no vessels and no other clues for melanoma. Histopathology showed a compound common melanocytic nevus, blue nevus in the centre of the lesion with no signs of atypia. Up to now, only 25 cases of CN with dermatoscopic description have been published, withno precise dermatoscopic features established yet. Therefore, studies with larger number of cases are needed for the final conclusions.
Implicit and Explicit Examples of the Phenomenon of Deviant Encodings
Authors: Quinon Paula 
Published: November 2020

Abstract
The core of the problem discussed in this paper is the following: the Church-Turing Thesis states that Turing Machines formally explicate the intuitive concept of computability. The description of Turing Machines requires description of the notation used for the input and for the output. Providing a general definition of notations acceptable in the process of computations causes problems. This is because a notation, or an encoding suitable for a computation, has to be computable. Yet, using the concept of computation, in a definition of a notation, which will be further used in a definition of the concept of computation yields an obvious vicious circle. The circularity of this definition causes trouble in distinguishing on the theoretical level, what is an acceptable notation from what is not an acceptable notation, or as it is usually referred to in the literature, “deviant encodings”.
Deviant encodings appear explicitly in discussions about what is an adequate or correct conceptual analysis of the concept of computation. In this paper, I focus on philosophical examples where the phenomenon appears implicitly, in a “disguised” version. In particular, I present its use in the analysis of the concept of natural number. I also point at additional phenomena related to deviant encodings: conceptual fixed points and apparent “computability” of uncomputable functions. In parallel, I develop the idea that Carnapian explications provide a much more adequate framework for understanding the concept of computation, than the classical philosophical analysis.
Data-Driven Dialogue Models: Applying Formal and Computational Tools to the Study of Financial And Moral Dialogues
Authors: Yaskorska-Shah Olena 
Published: November 2020

Abstract
This paper proposes two formal models for understanding real-life dialogues, aimed at capturing argumentative structures performatively enacted during conversations. In the course of the investigation, two types of discourse with a high degree of well-structured argumentation were chosen: moral debate and financial communication. The research project found itself confronted by a need to analyse, structure and formally describe large volumes of textual data, where this called for the application of computational tools. It is expected that the results of the proposed research will make a contribution to formal systems modelling and the evaluation of communication from the point of view of argument soundness.
The Influence of VAT Variation on the Damages Resulting from Fraud in the Romanian Economy
Authors: Miron Gabriela Monica 
Published: November 2020

Abstract
The purpose of this article is to determine the influence of the VAT rates variation, on different fields of activity of national economy, on the damage caused to the state's consolidated budget, from the point of view of the damage caused and damage recovered the damage that is caused by economical-financial offenses. Between 2011 and 2019, the VAT rate registered a continuous decrease from 24% to 19%, which significantly reduces the amount of damage caused and recovered.
Our study intends to point out the fact that in Romania, the various VAT rate had a major income on the damage caused as well as the damage recovered, thus leading to a decrease in several fields of activity. On the opposite side, there were fields of activity where a major increase of damage was registered, considering that the VAT rate decreased all along the period of time analyzed, such is the case of recycled materials. In some cases, the VAT decrease determined significant diminution of the damage caused and not of the damage recovered and in other cases, it had an effect only on the damage recovered or had no effect at all.
