Purpose – The purpose of this paper is twofold: (1) to assess importance-performance analysis (IPA) and service performance (SERVPERF) conceptualizations of service quality, and to establish which one excels in predicting the tourists' satisfaction in hotel industry; and (2) to test the mediating role of satisfaction between quality conceptualization and hotel guests’ repurchase intentions and word of mouth recommendations regarding the hotel. Design – A conceptual framework was empirically tested on a sample of 311 tourists staying in six hotels in Sarajevo (Bosnia and Herzegovina), which is a tourist destination with increased relevance internationally. Methodology – Covariance-based structural equation modeling was used to estimate the model. Approach – Two conceptualizations were firstly estimated separately then they were contrasted and compared. Findings – The results showed a slight superiority of the IPA conceptualization over that of SERVPERF in predicting satisfaction and in affecting customer attitudinal and behavioral outcomes. This study also confirms the vital mediating role of satisfaction on customer outcomes. Originality of the research – This study utilizes and compares two relevant conceptualizations of hotel service quality and is based on a conceptual framework that establishes which one is better for predicting tourists’ behavioral outcomes. The study is of practical relevance since it gives suggestions on tools that should be used by hotel managers in assessing the quality perceived by their guests.

of the flaws of Bosnia’s political system, namely the strict nature of the ethnic power-sharing institutions that favour ethnically exclusive parties and zero sum politics, few will agree with his suggestions on how to fix the system. In short, Bennett asks all the right questions but gives, sadly, all the wrong answers. Bosnia does not need another externally imposed system, instead, it has become obvious that real change must come from within Bosnia. There are signs that the system can change, and protests in recent years have demonstrated that people are more and more dissatisfied with the system. In addition to the above-mentioned flaws in Bennett’s argument, there is also a lack of empirical evidence that his suggestion would work. This not only refers to a more and more passive international community when it comes to Bosnia, but also to the fact that Horowitz’s theory of centripetalism is barely used and has not been tried in other postwar societies. To assume people can be ‘re-programmed’ and will just change their preferences in voting if the electoral system changes also assumes that ethnic identity and clientelistic networks will just go away with new electoral rules. There is no empirical evidence for this, and when Horowitz’s electoral preference system was used in the 2000 election for Republica Srpska’s Presidency, it made absolutely no difference to the way people voted. Overall, the book is interesting for anyone interested in Bosnia, the Balkans and international state-building. While Bennett adds little to the academic debate on Bosnia, he provides some interesting insights on debates about topics such as constitutional reform, police reform, the implementation of the rule of law, and the inner workings of the Office of the High Representative. While generally well written, at times the book is repetitive, and it is not well referenced.

Future wireless networks are expected to constitute a distributed intelligent wireless communications, sensing, and computing platform, which will have the challenging requirement of interconnecting the physical and digital worlds in a seamless and sustainable manner. Currently, two main factors prevent wireless network operators from building such networks: (1) the lack of control of the wireless environment, whose impact on the radio waves cannot be customized, and (2) the current operation of wireless radios, which consume a lot of power because new signals are generated whenever data has to be transmitted. In this paper, we challenge the usual “more data needs more power and emission of radio waves” status quo, and motivate that future wireless networks necessitate a smart radio environment: a transformative wireless concept, where the environmental objects are coated with artificial thin films of electromagnetic and reconfigurable material (that are referred to as reconfigurable intelligent meta-surfaces), which are capable of sensing the environment and of applying customized transformations to the radio waves. Smart radio environments have the potential to provide future wireless networks with uninterrupted wireless connectivity, and with the capability of transmitting data without generating new signals but recycling existing radio waves. We will discuss, in particular, two major types of reconfigurable intelligent meta-surfaces applied to wireless networks. The first type of meta-surfaces will be embedded into, e.g., walls, and will be directly controlled by the wireless network operators via a software controller in order to shape the radio waves for, e.g., improving the network coverage. The second type of meta-surfaces will be embedded into objects, e.g., smart t-shirts with sensors for health monitoring, and will backscatter the radio waves generated by cellular base stations in order to report their sensed data to mobile phones. These functionalities will enable wireless network operators to offer new services without the emission of additional radio waves, but by recycling those already existing for other purposes. This paper overviews the current research efforts on smart radio environments, the enabling technologies to realize them in practice, the need of new communication-theoretic models for their analysis and design, and the long-term and open research issues to be solved towards their massive deployment. In a nutshell, this paper is focused on discussing how the availability of reconfigurable intelligent meta-surfaces will allow wireless network operators to redesign common and well-known network communication paradigms.

This paper deals with the architecture of the most prominent architect in Bosnia and Herzegovina during the Austro-Hungarian time, Josip Vancaš, and two of his most appreciated designs developed for Banja Luka: Landesbank branch office and villa Husedžinović. They both belong to what Vancaš promoted to be "Bosnian style" in architecture, while the latter one is widely accepted as one of his best single-family housing designs. The paper foremost shows Vancaš's biography and a short overview of his professional development and then focuses on the discussion of his contribution to the so-called Bosnian style in architecture, and its reflections to mentioned designs in Banja Luka, originally contributing to this still active question in the history of architecture.The paper gives data on the original status of the buildings, as well as their development throughout history, with reflections to contemporary time. The concluding discussion reviews Vancaš's contribution to architecture in the period of 1878-1918, as well as the promotion of new thoughts outside the usual work of a typical architect.

In this paper, a novel interference mitigation and power allocation (PA) scheme is investigated for downlink non-orthogonal multiple access (NOMA) with multiple input multiple output (MIMO) technology in heterogeneous networks (HetNets). The proposed scheme, named PA based interference alignment and coordinated beamforming (PA-IA-CB), consists of two stages. The first stage applies two steps of IA-CB; one step for canceling the inter-cluster and the co-tier interference among small cells, whereas the other step deals with the inter-cluster interference within the macro cell. In the second stage, the cross-tier interference is proposed to be managed by properly handling the allocated power to the macro base station (MBS) and the small base stations (SBSs). The PA problem is modeled as a non-cooperative game between the MBS and the SBS with the aim of increasing the system sum rate. Simulation results verify the efficiency of the proposed technique in terms of total system sum rate and outage probability compared to the conventional schemes.

Irritable bowel syndrome (IBS) is a brain‐gut disorder, of which the natural course varies between patients and is difficult to predict. This study aimed to evaluate symptom evolution over a 5‐year follow‐up period and to identify baseline predictors for symptom severity and quality of life (QoL) at follow‐up.

Youth unemployment rate in Bosnia andHerzegovina (BiH) is one of the largest in the world. Ahigh percentage of unemployed and inactive young peopleis the result of on the one hand, insufficiently rapid economicdevelopment of small post-transition economies andon the other hand, the mismatch of supply and demand inthe labor market. In the long run, reformed modern formaleducation at all levels, as well as non-formal education,particularly entrepreneurship and STEAMeducation, could make a significant contribution to economicgrowth and development of small post-transitiondeveloping economies, by strengthening the entrepreneurialecosystem of educational institutions at all levels and thedevelopment of entrepreneurship. The goal of the researchis, through the review of empirical studies, to analyze successfulpractices of applying entrepreneurship educationand building the entrepreneurial ecosystem in primary, secondaryand higher education and modeling strategic directionsof curriculum reforms at all levels of the educationsystem in small post-transition developing economies, witha focus on the reform of the education system of higher educationin the Republic of Srpska and Bosnia and Herzegovina.We used historical method, method ofclassification, method of analysis and synthesis, and a casestudy. In the case study, on the example of the University ofBanja Luka (UNIBL), we can conclude that UNIBL stilldoes not have the characteristics of entrepreneurship universityand that the reform of the University is necessary.

Istraživanje autohtone proizvodnje Livanjskog i Travničkog sira ima za cilj očuvanje tradicije, organizirane proizvodnje i plasmana na tržišta izvan domicilne regije. Autohtoni sirevi su raznovrsnijeg okusa, arome i konzistencije u odnosu na industrijski proizvedene sireve, gdje je tehnologija definirana, a uvjeti proizvodnje kontrolirani. Nadmorska visina, kvalitetna voda i hrana nisu dovoljni čimbenici za trajno održavanje kvalitete autohtonih sireva. Na osnovi standardizacije tehnoloških postupaka proizvodnje može se proizvesti sir specifičnog obilježja. Cilj istraživanja bio je odrediti i komparirati ukupni dušik i dušične frakcije u dva autohtona sira – Livanjskom i Travničkom, ovisno o terminu uzorkovanja (srpanj, kolovoz i rujan). Za anlizu su uzorci sira uzeti nakon 90 dana zrenja u izvornim uvjetima okoline. U uzorcima sira određivan je ukupni dušik i dušične frakcije. Određivanje sadržaja ukupnog dušika (TN), kao i dušika topljivog u vodi pri pH 4,6 (SN-4,6) i 12% trikloroctenoj kiselini (TCA-SN) provedeno je metodom po Kjeldahlu. Vrijednosti TN, SN-4,6 i TCA-SN u uzorcima Travničkog sira bile su niže u odnosu na uzorke Livanjskog sira pri svakom terminu uzorkovanja. Najveće vrijednosti indeksa SN-4,6/TN i TCA-SN/TN kod oba ispitivana sira utvrđene su u sirevima proizvedenim od mlijeka prikupljenog tijekom rujna. Indeksi zrenja su bili viši u uzorcima Travničkog sira, što ukazuje na povećanu primarnu proteolizu u odnosu na Livanjski sir, to može biti rezultat specifičnosti biljnog pokrivača i ispaše ovaca na nižoj nadmorskoj visini.

U radu su prikazani rezultati istraživanja opterećenosti teškim metalima na relaciji tlo-biljka-životinja područja Srednje-bosanskog kantona. Istraživanja su obuhvatila analizu sadržaja kadmija (Cd), žive (Hg) i željeza (Fe) u jetrenom i bubrežnom tkivu domaće janjadi. S područja općine Kakanj žrtvovano je 8 janjadi, od kojih su uzeti uzorci tkiva jetre i bubrega, a Zenice 7 janjadi, od kojih su također uzeti uzorci tkiva jetre i bubrega. Sadržaj teških metala (Cd, Hg i Fe) u uzetim uzorcima, utvrđen je na ICP-MS (masena spektrometrija s induktivno spregnutom plazmom), u skladu s evropskim standardima (EN 13805 : 2002, IDT) i (EN 15763, 2009, IDT). Utvrđena srednja količina Cd u uzorcima tkiva jetre s područja općine Kakanj iznosila je 0,115, a Zenice 0,261 mg/kg. Srednja vrijednost količine Cd u uzorcima tkiva bubrega sa područja općine Kakanj iznosila je 0,197, a Zenice 0,476 mg/kg. Sadržaj kadmija je veoma varijabilan na oba lokaliteta. Nije utvrđena statistički značajna razlika između lokaliteta. Općenito, sadržaj kadmija je ispod gornje granice dozvoljene količine prema Direktivi Europske Komisije. Utvrđene količine Fe na oba istraživana lokaliteta su znatno ispod gornje granice dozvoljenih vrijednosti. Na oba lokaliteta u uzetim uzorcima istraživanih tkiva nije utvrđena prisutnost žive.

TPS3155 Background: Genomic signatures are revolutionizing the definition, identification, and treatment of breast cancer. To precisely stratify breast cancers into actionable subgroups, full genome expression data and matching clinical data must be aggregated into a large data set. Such a data set will accelerate research and discovery, especially for smaller patient subsets who are not as widely represented within the current body of literature. Methods: FLEX is a multicenter, prospective, population-based, observational trial for patients with Stage I, II, and III breast cancer. All patients with stage I to III breast cancer who receive MammaPrint, with or without BluePrint on a primary breast tumor are eligible for enrollment. The study’s primary aim is to create a large scale, population-based registry of full genome expression data matched with clinical data to investigate new gene associations with prognostic and/or predictive value. Secondary objectives include utilizing the shared study infrastructure to examine and generate hypotheses for targeted subset analyses and/or trials based on full genome expression data. The design of FLEX allows targeted sub-studies and sub-analyses to be added as appendices after the initial baseline study is opened. Patients enrolled in the initial study are also eligible for inclusion in sub-studies where they meet all criteria and additional consent is not required. Additional clinical data will be collected as specified in the appendix protocols. The FLEX collaborative platform allows participating investigators the opportunity to author their own sub-study protocols, as approved by the FLEX Steering Committee of their peers. 13 sub-studies have already been identified and are under development. Eligibility: The study will enroll a minimum of 10000 patients aged ≥18 years with histologically proven invasive stage I-III breast cancer who signed informed consent. Enrollment began April 2017 and 1506 patients have been enrolled. Clinical trial information: NCT03053193.

Artefacts caused by the presence of metallic implants and prosthesis appear as dark and bright streaks in computed tomography (CT) images, that obscure the information about underlying anatomical structures. These phenomena can severely degrade the image quality and hinder the correct diagnostic interpretation. Although many techniques for the reduction of metal artefacts have been proposed in literature, their effectiveness is still limited. In this paper, an application of a convolutional neural networks (CNN) to the problem of metal artefact reduction (MAR) in the image domain is investigated. Experimental results show that image-domain CNN can substantially suppresses streaking artefacts in the reconstructed images.
