The purpose of this paper is to analyze a signal propagation in highly metalized environments, which has not been extensively studied in the literature. Having in mind a large number of such applications, better understanding and possibly finding a way of improving communication in these conditions would be highly beneficial.

The analysis is performed in a simulation environment developed by the authors, based on finite difference time domain (FDTD) method, to identify effects that have decisive influence on electromagnetic (EM) wave propagation in the aforementioned conditions. The analysis of the EM field at the reception is modified so that a multiple-field sampling is performed, and maximal values are further used. In practical realizations, this procedure could be implemented by using multiple antennas and selective combining at the reception.

Results show that the existence of metal objects (in the observed case, these are railway tracks), in combination with the appropriate choice of antenna parameters, can be favorably used to improve signal reception. The contribution is manifested through the reduction of the pathloss.

In the performed analysis, one should be aware of the limitations that the FDTD method brings. Those limitations are related to the size of the computational domain and discretization mesh refinement (possibility of modeling geometry in fine details).

Originality of this paper consists of the introduced modification in the analysis of signal propagation in heavily metalized environment. Namely, a multiple-field sampling in the reception zone (in one plane, dimensions λ × λ = 12.5 cm X 12.5 cm) is performed using several probes in simulation environment. In this way, a qualitative analysis is performed more efficiently, which made it is possible to distinguish and identify different propagation mechanisms.

Entrepreneurial orientation (EO) at the organizational level refers to the process which includes methods, practices and decision-making styles which enhance the company’s approaches to business. At the individual level, EO is assessed using the individual entrepreneurial orientation (IEO: Bolton and Lane, 2012) scale, comprising three dimensions: risk-taking, innovativeness and proactiveness. The purpose of this paper is to evaluate and further validate the Serbian adaptation of the IEO scale among students.

Two independent studies were conducted on total of 685 students from Serbia. In Study 1, participants completed the IEO scale, proactive personality scales, reinforcement sensitivity questionnaire and academic performance questionnaire. In Study 2, participants completed the IEO scale, proactive personality scales, HEXACO-60 and risky-choice decision tasks.

Results supported the three-factor structure and satisfactory reliability of the IEO scale and its subscales. Omitting one item from the innovativeness scale led to better model fit, thus resulting in a nine-item solution. Convergent validity correlations were confirmed, showing that each IEO subscale obtained the expected correlations with similar constructs.

A potential problem with divergent validity is discussed from the aspect of the adequacy of the constructs chosen for its testing. Overall findings indicate that the Serbian adaptation of the IEO scale is a brief instrument with adequate psychometric properties, which makes it suitable for both research and practical purposes. The limitations of the study and the instrument are also highlighted and discussed.

The study contributes to better understanding of the nature of EO and helps its accurate assessment.

The aim of this study is to examine how and in what way authentic leadership and affective employee commitment foster the learning organisation in the context of transitional market conditions. Acting as role factors, their relationships with the learning organisation were examined simultaneously, at leadership and employee level.

The study was conducted on a sample of 500 employees from various industries of Serbian transitional economy. For the research purposes, structural equation modeling (SEM) methodology was used.

The findings reveal that authentic leadership and employee commitment both play an important role. Specifically, authentic leadership directly and indirectly affects the learning organisation. The indirect effect is partially mediated by the employee affective commitment.

The focus of this study is limited to the role of authentic leadership in fostering the learning organisation. Apart from leadership and employee commitment, it might be assumed that other variables have the potential to play a role in fostering the learning organisation as well.

To the best of the authors’ knowledge, no previous study has focused on authentic leadership and employee commitment as an “enabling-mechanism” in fostering learning organisations in the context of transitional economies. Consequently, this paper provides theoretical and practical implications on how and in what way they impact a learning organisation by empirically studying them in the context of transitional market conditions.

The purpose of this article is to describe a proposition for the evaluation of citations of scientific papers, which could serve as a supplement to the existing Rule Book of the Ministry of the Republic of Serbia, which is used in the procedure of electing candidates for particular academic and research titles. The evaluation and quantitative presentation of the results and evaluation of citations were carried out on data taken from the database of the Current Research Information System of the University of Novi Sad (CRIS UNS), which is harmonized with the Rule Book of the Ministry with respect to the evaluation of published scientific results of researchers.

There are different criteria to evaluate the quality of scientific papers based on their citations. The pertinent parameters can be the total number of citations, the number of citations in a defined time period and by assigning the appropriate weighting values to the citations. This work proposes a procedure of assigning the citation weighting values based on the evaluation of the scientific results in which the citation appeared according to the Rule Book in the Republic of Serbia. Based on this, the authors introduced the impact factor of researchers as the ratio of the number of points of the evaluated citations and the number of points of the evaluated papers of the researcher.

Results showed that the research information system CRIS UNS can be extended to the evaluation of citations for a single researcher, groups of researchers and institutions.

The proposed solution enables the evaluation of citations in the process of election and promotion of academic staff. In this way, there is a means for measuring the scientific influence of a researcher in the relevant scientific area.

The evaluation of citations may be included in the national strategies of scientific development, funding and evaluation of research projects; for promotions of academic staff at the universities and other academic institutions; and ranking of researchers and research organizations.

The main idea presented in the paper is the definition of a rule book (or several rule books) for the evaluation of citations. Based on the evaluation of citations, the authors proposed the term “the impact factor of researcher”.

Dissertations from the University of Novi Sad (UNS) are integrated with the research information system called the current research information system (CRIS) UNS. This paper aims to present a proposal for an extension of this system to enable the storage of student papers as prescribed by PhD study exam obligations. The proposed extension enables preservation and improves discoverability of scientific and technical works produced by students during their PhD studies.

An analysis of examination modes in accredited PhD study programs has been conducted. It was noted that students in examination modes verify the obtained results in the form of scientific and technical work. The main idea of this paper is to enable the preservation of those student results and to implement electronic services for retrieving those results by current and future PhD students to empower the development of science.

The proposal includes an extension of the CRIS UNS to store and publish student papers as prescribed as a PhD study exam obligation; an extension of the CERIF data model to enable storing of student papers; cataloguing student papers in the MARC 21 format; and a way to represent student papers in the Dublin Core format.

This paper can be a starting point for initiatives for the creation of institutional, regional, national and international Web portals for searching and browsing papers by PhD students.

This system offers the improvement of cooperation between PhD students from different institutions and countries.

The paper presents an extension of institutional, national and international current research information system (CRIS) systems which will enable the preservation and improve discoverability of student papers produced during PhD studies. The proposed extension has been verified by its implementation within the CRIS UNS system, which also supports monitoring of the scientific competencies of students based on an automatic evaluation of published scientific results.

Lorentz force evaluation is a non-destructive evaluation method for conducting specimens. The movement of a specimen relative to a permanent magnet leads to Lorentz forces that are perturbed in the presence of a defect. This defect response signal (DRS) is used for defect reconstruction. To solve a linear inverse problem for defect reconstruction, an accurate and fast forward computation method is required. As existing forward methods are either too slow or too inaccurate, the purpose of this paper is to propose the single voxel approach (SVA) as a novel method.

In SVA, the DRS is computed as a superposition of DRSs from single defect voxels, which are calculated in advance, by applying the boundary element source method. This research uses a setup of an isotropic conducting specimen, a spherical permanent magnet and defects of different shapes at different depths. With the help of simulations, this study compares the SVA to the previously proposed approximate forward solution (AFS) and the extended area approach (EAA) using the normalized root mean square error (NRMSE). Simulated data using the finite element method serve as the reference solution.

SVA shows across all simulations NRMSE values <2.5 per cent compared to <8 per cent for EAA and <12 per cent for AFS.

The superposition principle of SVA allows for the application of linear inverse methods for defect reconstruction while providing sufficient accuracy of the forward method.

In investigating the linkage between intellectual capital (IC) and innovation, it is important not only to explore how IC as a whole is associated with organizations’ innovative performance but also to gain a deep understanding of the role of different IC components (groups of intangibles) in companies’ innovation performance, which is the purpose of this paper in the context of Serbian companies.

This research is based on survey data collected from 100 Serbian companies with at least 100 employees during 2014/2015. Six IC components were analyzed (human, structural, internal relational, external relational, renewal and entrepreneurial) in terms of their effect on innovation performance. Analyses were conducted using structural equation modeling and correlation analysis.

Findings demonstrate that renewal capital, internal relational capital and structural capital have statistically significant positive effects on overall innovative performance in Serbian companies.

The outcomes reveal potential and barriers within IC that are crucial to innovation performance in Serbian companies. In this way, this study enables a deeper understanding of intangible drivers of innovation and highlights possibilities to foster intangible innovation potential in Serbian companies.

As context (economic and cultural) has emerged as a relevant factor in researching IC, this study is original in investigating IC effect on innovation within the Serbian business environment. Additionally, the broad sexpartite taxonomy of IC contributes to a wider understanding of knowledge and its linkages to innovation.

Cookies were not generally viewed as functional contributors to well-being as they are primarily perceived as confectionery products. The purpose of this paper is to evaluate the potential of flaxseed-enriched cookies as carriers of lignans and omega-3 fatty acids – functional compounds that are lacking in the western diet.

An online questionnaire collected data from Croatian consumers (n=1,035). The majority of the samples were women (73 per cent) in the age range 15-65 years (97 per cent). Most participants were employed, had a higher education degree, and lived in urban areas. Questions examined the consumption of cookies and flaxseed, interest for functional cookies, nutritional knowledge, and awareness.

Majority of subjects consumed cookies (93 per cent), while 61 per cent did not eat flaxseed or ate it less than once a month. The consumers showed elevated interest for the functional cookies with flaxseed, among which elderly women with higher nutrition awareness, and nutrition knowledge were the most interested. Functional cookies with flaxseed could be used for delivery of lignans and omega-3 fatty acids in everyday diet, but in order to reach wider range of consumers producers might benefit from employing nutritional educational marketing campaigns.

Data from the study decreased scarcity of information on consumer behaviour related to flaxseed consumption and on potential use of cookies as a functional food. Reported findings will be useful to dieticians, food industry, and food researchers in countries with a high prevalence of cookie consumption.

This paper aims to examine the development and piloting of a novel European framework for community engagement (CE) in higher education, which has been purposefully designed to progress the CE agenda in a European context.

The proposed framework was co-created through the European Union (EU)-funded project towards a European framework for community engagement in higher education (TEFCE). The TEFCE Toolbox is an institutional self-reflection framework that centres on seven thematic dimensions of CE. This paper follows the development of the TEFCE Toolbox through empirical case study analysis of four European universities and their local communities.

The findings in this paper indicate that the TEFCE Toolbox facilitates context-specific applications in different types of universities and socioeconomic environments. Incorporating insights from engagement practitioners, students and community representatives the TEFCE Toolbox was successfully applied in universities with diverse profiles and missions. The process facilitated the recognition of CE achievements and the identification of potential areas for improvement.

Despite a range of international initiatives, there remains an absence of initiatives within the European higher education area that focus on developing tools to comprehensively support CE. The TEFCE Toolbox and case-study analysis presented in this paper address this gap in knowledge. The broader societal contribution and social responsibility of higher education have become increasingly prominent on the European agenda. The TEFCE Toolbox represents an innovative, robust and holistic European framework with the potential to support universities in reflecting upon their pursuit of addressing grand societal challenges, whilst promoting CE.
