Competitiveness and the EU Accession Process: Can Candidate Countries Become Competitive as EU Countries?
Authors: Stanković Jelena J. , Džunić Marija , Milić Vesna Janković 
Published: May 2020

Abstract
Economic growth and competitiveness are usually analysed at the level of the national economy in traditional economic research. The problem of competitiveness within this line of thought is mainly regarded from the perspective of determining the sources of sustainable growth, which makes the economy more competitive than others. Competitiveness, therefore, is a multidimensional concept, which includes a range of factors, such as institutions, infrastructure, macroeconomic environment, market, human capital and technological development. Also, the process of joining the European Union significantly stimulates the development of the exact categories that are relevant for acceleration of the economic development. The aim of the paper is to assess the competitiveness of the candidate or potential candidate countries for membership in the European Union, through a comparative analysis of their competitiveness vis-à-vis EU countries. The results indicate that the competitiveness of the EU 15 countries, measured by Global Competitiveness Index and GDP per capita, is statistically significantly higher than the competitiveness of EU country group enlarged in the period 2004-2013, also compared to EU candidate or potential candidate countries. However, when it comes to the pillar of competitiveness related to the macroeconomic environment, according to the latest Global Competitiveness Report (2017-2018), the scores of the EU countries associated with enlargements in the period 2004-2013 are statistically significantly better than the EU 15 countries.

Authors: Krajišnik Milenko , Popović Sanja 
Published: May 2020

Abstract
The competitiveness of the national economy, its sectors and companies is essential for economic growth and development in the conditions of the global market. This importance is especially expressed for small open economies, such as Bosnia and Herzegovina (B&H). Bosnia and Herzegovina must strengthen its export position in the most competitive sectors, so that it can develop under conditions of increasingly liberalized world trade, with growing competition. The aim of this paper is to investigate the sectora structure of B&H exports, the competitiveness, significance and performance of certain sectors, in order to identify weaknesses and possible ways o improvement. For the purposes of this analysis, the Trade Competitiveness Map analysis methodology was used to assess the competitiveness of the sector, using the Trade Performance Index (TPI). The main aim of the methodology is to determine sectoral export performance, in order to facilitate strategic market research and monitoring of national foreign trade performance. B&H has the poor export sector structure, with the low level o international competitiveness, reflected in the large share of resource intensive products and low-value processing products with low added value Improving competitiveness could be achieved by strengthening the most competitive sectors, as well as by changing the economic structure towards the development of technologically intensive and highly profitable sectors o the economy.
Breaking the Testing Pyramid with Virtual Testing and Hybrid Simulation
Authors: You Shawn , Gao X. Shawn , Nelson Arlin 
Published: May 2020

Abstract
Virtual testing and hybrid simulation have become an important trend in airplane design and validation. The traditional Testing Pyramid (or Building Block) approaches that emphasis on uniaxial coupon test and full structure certification test are being challenged. Researchers are trying to use advanced testing and simulation methods to replace the Testing Pyramid approach.
Before physical testing, virtual testing can be conducted to simulate the physical test. Virtual model of the full testing system including controller, actuators, and fixtures can be constructed and validated. In this work, an example has been developed and validated to show the potentials of the virtual testing process.
Hybrid simulation is an approach of analyzing an analysis model and physical structure integrated system under realistic loading conditions. Hybrid simulation combines the lab testing with numerical analysis to explore the benefits of both methodologies. In this study, a hybrid simulation for a simplified airplane wing was conducted to demonstrate the process.
Virtual testing and hybrid simulation are alternative methods of Testing Pyramid approach. Full scale tests are still required for certification but the more that is known about the test article, the greater chances of success in the full-scale certification testing.

Impact of cyclin D1 and DJ-1 on diagnosis, clinico-pathological features and outcome in prostate cancer and benign prostatic hyperplasia
Authors: Mohammed Amrallah A. , Ibrahim Hanna M. , Atwa Hanna A. , Elshentenawy Ayman , Elwan Amira 
Published: May 2020

Abstract

Background
Disturbance in cell cycle regulatory genes is a common finding among many types of cancers. The aim of this study is to evaluate the role of cyclin D1 and DJ-1 in benign prostatic hyperplasia (BPH) and prostate cancer (PC).

Method
The current study enclosed 40 patients diagnosed with PC and 40 cases of BPH. The expression level of cyclin D1 and DJ-1 were evaluated by immunohistochemistry (IHC). Cyclin D1 scored depending on the percentage of stained nuclear tumor cells. While scoring of DJ-1 was based on intensity. The results were correlated with clinicopathological features and outcome.

Results
In the PC group, cyclin D1 was detected in 95% and overexpressed in 42.5%, DJ-1 was positively stained in 85% and overexpressed in 47.5%. Meanwhile, in the BPH group, cyclin D1 was not detected and DJ-1 stained in only 2.5%. There was a statistically significant difference in Gleason score (GS), tumor stage, size, and treatment failure (p =< 0.001). In the terms of PC diagnosis prediction, although cyclin D1 was more specific (100%), DJ-1 is more sensitive than cyclin D1 (80%, 70%, respectively) (p = 0.000).

Conclusions
Cyclin D1 and DJ-1 may emerge as a promising way for diagnosis of PC in certain circumstances, as the presence of insufficient tissue sampling, small foci of carcinoma or benign lesions mimic PC. This is in addition to the known role of cyclin D1 and DJ-1 in PC prognosis.
Forest management practices and the occurrence of suspended solids in rivers and streams and their influence on ichthyofauna and river ecosystems
Authors: Mikołajczyk Tomasz , Nawrocki Przemysław 
Published: May 2020

AbstractThis article is based on a literature review and attempts to highlight the harmful effects of forest soil erosion on aquatic ecosystems with particular emphasis on ichthyofauna. We focus on the phenomena of excessive soil erosion caused by forest management practices and forest roads, subsequent sediment runoff as well as silting of watercourses and their impact on fish. Among others, the direct influence of the suspended sediments on fish reproduction, egg incubation, respiratory processes, growth and immunity, as well as indirect effects on habitat and migration are discussed. The authors’ intention is to draw attention to this important and underestimated aspect of forest management in Poland. The aim of this publication is to bring about changes in the management of commercial forests that will minimize the erosion of forest soils, formation of high levels of suspended solids in rivers and in turn limit their negative impact on aquatic ecosystems.
Immunohistochemical Studies of αSMA in the Epididymis of African Four-Toed Hedgehog (Atelerix albiventris)
Authors: Olukole S. G. , Coker O. M. , Oke B. O. 
Published: May 2020

AbstractThe epididymis plays an important role in sperm maturation, storage, transport and in the secretion of enzymes and proteins into the tubular lumen. In this study, we examined the histology, microstereology and immunohistochemical localization of alpha smooth muscle (αSMA) in the three regions of the epididymis of the African four-toed hedgehog (Atelerix albiventris). Ten adult males were captured from the wild in Ibadan, Nigeria, between May and October, 2016. The animals were euthanized and the epididymis (caput, corpus and cauda regions) were retrieved and fixed in buffered neutral formalin ahead of the paraffin technique, following standard procedures. The duct of the epididymis was lined by pseudostratified columnar epithelium comprising basal, principal and apical cells as well as intraepithelial lymphocytes in proximity to basal cells. The principal cells, the major cells encountered within the epididymal epithelium of the animal, decreased in population from the caput to the cauda epididymidis while the apical cells were more abundant in the cauda epididymidis. Positive reactions to αSMA were observed in the peritubular muscular coat of the epididymal duct as well as blood vessels across the three regions of the epididymis with the caput and cauda epididymidis showing stronger positive reactions compared to the corpus epididymidis. This study demonstrated that the histology, microstereology as well as the cellular constituents of the epididymal duct of theAtelerix albiventrisare similar to those of other mammals with a slight variation. It has also highlighted variation in the localization of αSMA across the regions of the epididymis of the animal.

Authors: Galatis Nikolaos , Nitsi Ekaterini , Theloura Chrysoula 
Published: May 2020

Abstract
This paper investigates the financial performance of 37 low-rated and high-rated global ETFs during QE-Tapering. Weekly data are employed that cover the period from October 27, 2014 until September 24, 2018. The estimations are based on the well-known CAPM model. The measures employed are the Sharpe and Treynor ratios as well as the Jensen’s alpha, the beta and the a/b measures. Results indicate no existence of selectivity skills neither in low- nor in high-rated ETFs. It should be noted that low-rated ETFs exhibit bearish behavior whereas high-rated ones present bullish behavior. Thereby, one can see that high-rated ETFs are better able to outperform the market during periods of normalization of monetary policy after extra easing action taking has been terminated.
Lavandula angustifolia and Oxalis pes-caprae, hosts of Meloidogyne hapla and Meloidogyne javanica - A note for Meloidogyne luci in Greece
Authors: Gonçalves A.R. , Conceição I.L. , Kormpi M. , Tzortzakakis E.A. 
Published: May 2020

Summary
Root-knot nematodes (RKN), Meloidogyne spp., have a wide host range and are common in the Mediterranean area. Cultivated lavender (Lavandula angustifolia) was found naturally infested by M. hapla in Kozani area, the first documented infestation of this crop by RKN in Greece. Oxalis pescaprae, a common winter weed in Crete, was found to be a host of M. javanica under artificial inoculation. This weed acts as a potential winter host of the nematode in fields cultivated with vegetable crops. Two populations of M. ethiopica were found in kiwi and maize in Greece in the past. Recently, populations of M. ethiopica from Europe were re-classified as M. luci, based only on the population isolated from kiwi for Greece. In the current work, the RKN populations originating from kiwi and maize and maintained on tomato, were identified as M. luci. Nematode species identification was determined by electrophoretic analysis of protein extracts obtained from females.
Cities drifting apart: Heterogeneous outcomes of decentralizing public education
Authors: Brutti Zelda 
Published: May 2020

Abstract
Looking at the decentralized provision of public education in a middle-income country, this paper estimates the impact of local autonomy on service quality, finding large heterogeneity in the effect across different levels of local development. In the year 2002, Colombian municipalities were entrusted with autonomous management of their local public education based solely on a population threshold. I estimate the impact that autonomy has had on education performance across the territory, using a municipality and time fixed-effects model. I find a quality gap arising between highly developed and low-developed autonomous municipalities, in a trend that reinforces over time: the reform has induced regional inequality in education quality. I am able to support the hypothesis that autonomous and nonautonomous municipalities were on similar performance trends before decentralization was implemented, even when looking within different local development ranges. Based on the analysis of detailed municipal balance sheet data and administration indicators, I argue that local administration capacity represents the most likely explanation of why the autonomy-related discrepancies have been arising.
Anaesthesia for Liver Transplantation: An Update
Authors: Brezeanu Lavinia Nicoleta , Brezeanu Radu Constantin , Diculescu Mircea , Droc Gabriela 
Published: May 2020

Abstract
Liver transplantation (LT) is a challenging surgery performed on patients with complex physiology profiles, complicated by multi-system dysfunction. It represents the treatment of choice for end-stage liver disease. The procedure is performed under general anaesthesia, and a successful procedure requires an excellent understanding of the patho-physiology of liver failure and its implications. Despite advances in knowledge and technical skills and innovations in immunosuppression, the anaesthetic management for LT can be complicated and represent a real challenge. Monitoring devices offer crucial information for the successful management of patients. Hemodynamic instability is typical during surgery, requiring sophisticated invasive monitoring. Arterial pulse contour analysis and thermo-dilution techniques (PiCCO), rotational thromboelastometry (RO-TEM), transcranial doppler (TCD), trans-oesophageal echocardiography (TEE) and bispectral index (BIS) have been proven to be reliable monitoring techniques playing a significant role in decision making. Anaesthetic management is specific according to the three critical phases of surgery: pre-anhepatic, anhepatic and neo-hepatic phase. Surgical techniques such as total or partial clamping of the inferior vena cava (IVC), use of venovenous bypass (VVBP) or portocaval shunts have a significant impact on cardiovascular stability. Post reperfusion syndrome (PRS) is a significant event and can lead to arrhythmias and even cardiac arrest.

Authors: Lima Vânia Mara Alves , dos Santos Cibele Araújo Camargo Marques , Rozestraten Artur Simões 
Published: May 2020

Abstract

Purpose
This paper presents the ARQUIGRAFIA project, an open, public and nonprofit, continuous growth web collaborative environment dedicated to Brazilian architectural photographic images.

Design/methodology/approach
The ARQUIGRAFIA project promotes the active and collaborative participation among its institutional users (GLAMs, NGOs, laboratories and research groups) and private users (students, professionals, professors, researchers), both can create an account and share their digitized iconographic collections in the same Web environment by uploading their files, indexing, georeferencing and assigning a Creative Commons license.

Findings
The development of users interactions by means of semantic differentials impressions recording on visible plastic-spatial aspects of the architectures in synthetic infographics, as well as by the retrieval of images through an advanced system search based on those impressions parameters. By gamification means, the system often invites users to review images’ in order to improve images’ data accuracy. The pilot project named Open Air Museum that allows users to add audio descriptions to images in situ. An interface for users’ digital curatorship will be soon available.

Research limitations
The ARQUIGRAFIA’s multidisciplinary team gathering professors-researchers, graduate and undergraduate students from the Architecture and Urbanism, Design, Information Science, Computer Science faculties of the University of São Paulo, demands continuous financial resources for grants, for contracting third party services, for the participation in scientific events in Brazil and abroad, and for equipment. Since 2016, significant budget cuts in the University of São Paulo own research funds and in Brazilian federal scientific agencies can compromise the continuity of this project.

Practical implications
The open source template called +GRAFIA that can freely help other areas of knowledge to build their own visual Web collaborative environments.

Originality/value
The collaborative nature of the ARQUIGRAFIA distinguishes it from institutional image databases on the internet, precisely because it involves a heterogeneous network of collaborators.

Authors: Park Ziyoung , Lee Hosin , Kim Seungchon , Park Sungjae 
Published: May 2020

Abstract

Purpose
This research project aims to organize the archival information of traditional Korean performing arts in a semantic web environment. Key requirements, which the archival records manager should consider for publishing and distribution of gugak performing archival information in a semantic web environment, are presented in the perspective of linked data.

Design/methodology/approach
This study analyzes the metadata provided by the National Gugak Center’s Gugak Archive, the search and browse menus of Gugak Archive’s website and K-PAAN, the performing arts portal site.

Findings
The importance of consistency, continuity, and systematicity—crucial qualities in traditional record management practices—is undiminished in a semantic web environment. However, a semantic web environment also requires new tools such as web identifiers (URIs), data models (RDF), and link information (interlinking).

Research limitations
The scope of this study does not include practical implementation strategies for the archival records management system and website services. The suggestions also do not discuss issues related to copyright or policy coordination between related organizations.

Practical implications:
The findings of this study can assist records managers in converting a traditional performing arts information archive into a semantic web environment-based online archival service and system. This can also be useful for collaboration with record managers who are unfamiliar with relational or triple database system.

Originality/value
This study analyzed the metadata of the Gugak Archive and its online services to present practical requirements for managing and disseminating gugak performing arts information in a semantic web environment. In the application of the semantic web services’ principles and methods to an Gugak Archive, this study can contribute to the improvement of information organization and services in the field of Korean traditional music.
