Goodwill impairment test disclosures under IAS 36: Compliance and disclosure quality, disclosure determinants, and the role of enforcement
Authors: Gros Marius , Koch Sebastian
Published: January 2019

Prior research documented that higher disclosure quality reduces information asymmetry and the cost of capital. Accordingly, firms have an incentive to comply with disclosure requirements and to provide voluntary disclosure. However, prior research on mandatory disclosures on goodwill impairment testing reveals low compliance among European firms. In this paper, we contribute to the literature and assist regulators, enforcers, and standard setters by shedding light on the determinants of the observed low levels of compliance and voluntary disclosure. Consistent with economic theory, we reveal that firms determine the level of disclosure strategically. We find firms with higher preparation and proprietary cost to show lower compliance and less voluntary disclosure while firms with higher growth opportunities provide better compliance and more voluntary disclosure. However, the strategic behavior is constrained by enforcement. Consequently, our results are more (less) pronounced within a weak (strong) enforcement environment.
Symbolic potential of place and its modelling for management needs.
Authors: Petrušonis Vytautas
Published: January 2019

Knowledge about the symbolic potential of the place (for example, city main square) and the form of presentation of such data is very important for better understanding of cultural memory of place. The article presents examples of symbolic potential descriptions of place using specific symbolic code sets. Code units consists from 1) names of identified easy recognizable objects forming a place and 2) cultural ideas, connotational characteristics of those objects. Some ideas appear as simple cultural connotations of certain objects and are easily identifiable. However, the fuller knowledge of local symbolic potential requires using of data that have more complex connotational structure. Such ideas encourage designers to comprehend the distinctive features of the place more deeply; also they are helping them to take into account personal existential experiences that are essential for the stimulating of original creative design solutions. Data about the place can help to manage it taking into account the symbolic potential only in case when the connotational characteristics are included into that data set. To ensure consensus among all relevant actors, data about place (city square, etc) expressed in codes with more complex connotational structures must be presented in explicit form (as some kind of semantic „reference book“) together with the arguments of their significance. Such codes would help align the positions of all actors involved in the management of certain place. Codes of this kind need to be defined in advance by making the appropriate research activities before and included in the legal documents regulating place management. The article discloses the model of symbolic potential of Kaunas Unity Square (Vienybės aikštė) and its closest
environment, formed in period after regaining independence in 1918. In order to protect ourselves from possible unscrupulous modernization of square, we always have to take into account the symbolic potential of this place when planning even the smallest changes of square. Research of symbolic potential of the place was conducted using theoretical methods: abstraction, analogy, generalization, reasoning (inductive, deductive, and abductive), synthesis. Moreover, the methods of phenomenology and semantic analysis were applied also.

Published: January 2019

Defects in hepatic lipid metabolism cause nonalcoholic fatty liver disease and insulin resistance, and these pathologies are closely linked. Regulation of lipid droplet metabolism is central to the control of intracellular fatty acid fluxes, and perilipin 5 (PLIN5) is important in this process. We examined the role of PLIN5 on hepatic lipid metabolism and systemic glycemic control using liver-specific Plin5-deficient mice (Plin5LKO). Hepatocytes isolated from Plin5LKO mice exhibited marked changes in lipid metabolism characterized by decreased fatty acid uptake and storage, decreased fatty acid oxidation that was associated with reduced contact between lipid droplets and mitochondria, and reduced triglyceride secretion. With consumption of a high-fat diet, Plin5LKO mice accumulated intrahepatic triglyceride, without significant changes in inflammation, ceramide or diglyceride contents, endoplasmic reticulum stress, or autophagy. Instead, livers of Plin5LKO mice exhibited activation of c-Jun N-terminal kinase, impaired insulin signal transduction, and insulin resistance, which impaired systemic insulin action and glycemic control. Re-expression of Plin5 in the livers of Plin5LKO mice reversed these effects. Together, we show that Plin5 is an important modulator of intrahepatic lipid metabolism and suggest that the increased Plin5 expression that occurs with overnutrition may play an important role in preventing hepatic insulin resistance.

Polimer merupakan molekul besar yang terbentuk dari unit-unit berulang yang sederhana. Plastik yang merupakan salah satu polimer telah mengambil peran teknologi yang penting karena sifatnya yang ringan dan mudah dibentuk. Plastik mengalami perkembangan dan penggunaan luas yang berkembang dengan cepat, salah satu jenis polimer adalah polietilen (PE). Dalam rangka perluasan aplikasinya, PE perlu dimodifikasi untuk memperbaiki sifat-sifatnya. Salah satunya dengan cara penempelan molekul maleat anhidride (MAH) pada PE atau dikenal dengan cara grafting atau pencangkokan molekul. Proses penempelan MAH ini dapat mengakibatkan perubahan struktur pada PE. Perubahan struktur ini berkaitan dengan kemungkinan perubahan kristalinitas. Kristalinitas akan berpengaruh pada sifat fisis (densitas) dan sifat mekanik (modulus elastisitas dan kekuatan luluh). Pada penelitian ini dilakukan beberapa pengujian, yaitu uji tarik dengan menggunakan tensile tester, uji densitas dengan menggunakan densitometer kolom dan pengujian dengan spektroskopi FTIR (Fourier Transform Infra Red). Dari hasil pengujian dapat disimpulkan bahwa PE yang tergrafting yang mendapatkan perlakukan annealing mengalami perubahan sifat fisis dan mekanik, dimana nilainya semakin besar dengan pertambahan waktu pemanasan sampai pada waktu tertentu.

Connecting the Last.fm Dataset to LyricWiki and MusicBrainz. Lyrics-based experiments in genre classification
Authors: Bodó Zalán , Szilágyi Eszter
Published: January 2019

Music information retrieval has lately become an important field of information retrieval, because by profound analysis of music pieces important information can be collected: genre labels, mood prediction, artist identification, just to name a few. The lack of large-scale music datasets containing audio features and metadata has lead to the construction and publication of the Million Song Dataset (MSD) and its satellite datasets. Nonetheless, mainly because of licensing limitations, no freely available lyrics datasets have been published for research.

In this paper we describe the construction of an English lyrics dataset based on the Last.fm Dataset, connected to LyricWiki’s database and MusicBrainz’s encyclopedia. To avoid copyright issues, only the URLs to the lyrics are stored in the database. In order to demonstrate the eligibility of the compiled dataset, in the second part of the paper we present genre classification experiments with lyrics-based features, including bagof-n-grams, as well as higher-level features such as rhyme-based and statistical text features. We obtained results similar to the experimental outcomes presented in other works, showing that more sophisticated textual features can improve genre classification performance, and indicating the superiority of the binary weighting scheme compared to tf–idf.

Published: January 2019

In this work, an adaptive nonlinear control method, was applied to a synchronous generator and we give some initial results on the adaptive control of nonlinear systems which are exactly input-output linearizable by state feedback. Parameters adaptation is used as a technique to robustify the exact cancelation of nonlinear terms, which is called for the linearization technique. The performance of the proposed adaptive nonlinear control scheme is demonstrated by simulation results. These results show that the proposed method achieves the same high dynamic performance as vector control.
Impact Assessment of EU Funds on Company’s Performance in the Fish Processing Industry: The Case of Croatia
Authors: Božanić Katarina
Published: January 2019

IPARD is a pre-accession Programme that was implemented in the Republic of Croatia in the pre-accession period. Its main objectives were to assist candidate countries and potential candidate countries in their harmonization and implementation of the EU acquis, as well as preparation for utilization of the future EU funds. Given that IPARD pre-funding resources of the European Union enabled the financing of the modernization of the production plants of the fish processing industry, this paper analyzed the impact of the used funds on the a) business performance and b) business (organizational) capacity of IPARD users from the fish processing industry. The research was conducted in a non-experimental way divided into two parts: (1) an analysis of a set of indicators of business performance of companies from the sample (users of pre-accession EU funds) and (2) through a survey that examined the impact of using these resources on improving business (organizational) capacity. The results show that the profitability indicators of most users were not increased two years after the funds were received. But it is expected that the improved technical and technological conditions will help businesses in the future to increase the competitiveness of their products. When it comes to the results of the impact on business ability, it is evident that management has improved its capacities in terms of acquiring and developing the skills of preparing and running projects, investment planning or strengthening the willingness to use similar means in the future.
The challenge of death and ethics of social consequences: Death of moral agency
Authors: Kalajtzidis Ján
Published: January 2019

The present paper focuses on the issue of death from the perspective of ethics of social consequences. To begin with, the paper summarizes Peter Singer’s position on the issue of brain death and on organ procurement related to the definition of death. For better understanding of the issue, an example from real life is used. There are at least three prominent sets of views on what it takes to be called dead. All those views are shortly presented and analysed. Later, the theory of ethics of social consequences is briefly presented. The paper looks for the position of this ethical theory in connection to the issue of death. The issue of organ procurement, which is closely connected to the problem of defining death, is used as a means for a better understanding of the issue. The issue of death is studied through the categories of moral subject and moral object. Using the standpoint of ethics of social consequences enables us to distinguish between the death of a moral agent and the death of the organism. That helps to soften many issues associated with the topic.
The Impact of Human Resources Management on Job Involvement. The Mediating Role of Vertical Trust
Authors: Lewicka Dagmara , Pec Monika
Published: January 2019

The purpose of the study was to identify the relationship between Human Resources Management system (HRM system), vertical trust, and job involvement. This type of involvement in work is considered very important for an organisation because it affects the added value generated employees. It is also associated with the well-being felt by individuals and testifies to the satisfaction of their psychological needs. The study was conducted on a group of 227 employees of large and medium-size entities. The application of the Structural Equation Modelling (SEM) made it possible to confirm the relationship between the HRM system and job involvement with the mediating role of vertical trust in the examined relationship. In order to verify to what extent the job involvement variation can be explained by the HRM system, a multi-dimensional linear regression analysis was applied.
Financial Development and Investment in Botswana: A Multivariate Causality Test
Authors: Muyambiri Brian , Odhiambo Nicholas M.
Published: January 2019

This paper examines the causal relationship between financial development and investment in Botswana between 1976 and 2014. The autoregressive distributed-lag (ARDL) bounds testing approach and a trivariate Granger-causality model are employed. In order to capture the breadth and depth of the financial sector in the study country, both bank- and market-based financial development indices are used. The results show that there is a bidirectional Granger-causal relationship between both bank-based and market-based financial development and investment in the short run. In the long run, a distinct causal flow is found to prevail only from investment to bank-based financial development. Given the findings, the causal relationship between financial development and investment is not a given as implied in economic literature. For Botswana, policies that enhance both investment and market-based financial development should be employed in the short run.
The Business Cycle and Cycles in The Banking Sector in The Polish Economy in The Years 2000‒2017
Authors: Barczyk Ryszard
Published: January 2019

Apart from general business cycles, market economies are characterized by their specific cycles, which also include banking cycles. Fluctuations whose sequence over time creates the banking cycles are absolute or/and relative changes in the activity of banks, manifested in the form of oscillations in the supply of money and bank credits granted for investment or consumption purposes.

The aim of this article is to analyze the influence of general business cycles on changes in the activity of the central bank and commercial banks, and to examine a returnable relationship between banking activities and business cycles. The paper consists of two parts. The first one presents a theoretical hypothesis connected with the analyzed relations. The second part contains the results of the empirical analysis of the morphology of the cycles identified in the Polish economy. In the process of identifying the cycles under analysis, the concept of deviation cycles was taken into account. Deseasonalization was conducted using the Tramo/Seats procedure as part of the Demetra 2.0 package, and in the process of isolating cycles, the Hodrick-Prescott filter was accepted.
Types of Wounds and the Prevalence of Bacterial Contamination of Wounds in the Clinical Practice of Small Animals
Authors: Kožár M. , Hamilton H. , Koščová J.
Published: January 2019

Skin wounds are a common presentation in small animal practice. The successful management of wound healing in dogs and cats requires knowledge of the physiology of the wound healing process and the application of an appropriate therapeutic intervention. Many wounds are colonised by bacteria or show signs of clinical infection. Infections can delay wound healing, impair cosmetic outcome and increase healthcare costs. Because of a lack of papers giving an overall prevalence of bacteria in different types of wounds, 45 samples were taken from patients treated at the Small Animals Clinic, Section of Surgery, Orthopaedics, Roentgenology and Reproduction of the University of Veterinary Medicine and Pharmacy in Košice during the years 2017 — 2018 to determine the types of wounds and the prevalence of bacterial contamination of the wounds. Samples were obtained by using cotton-tipped swabs and then cultivated on Sabouraud’s plates in the Institute of Microbiology and Gnotobiology of the University. All 45 animals used in this research were first subjected to an anatomical and clinical exam to determine the patient’s health condition and the status of the wounds. Of these 45 samples, 9 were negative. Of the remaining 36 samples, 12 were cultivated and tested to give only the genera of the bacteria present, whilst 24 were tested more extensively for a specific diagnosis of the species. The most common wound was due to a bite from another animal; these made up 12 out of the 45 cases (26.67 %). There were 10 cases of dehiscence of old wounds (22.22 %), whereas there were only 2 cases of surgical wound complications (4.44 %). There were 5 puncture wounds or fistulas (11.11 %), 4 lacerations (8.88 %), 1 degloving injury (2.22 %), 1 seroma (2.22 %), 1 foreign body (2.22 %), 1 crushing injury (2.22 %), 1 case of contusion and necrosis (2.22 %), 1 cases of dermatitis with resulting pruritic lesions (2.22 %), and 1 cutting injury from a tight wire collar (2.22 %). Five cases (11.11 %) were wounds of unknown aetiology. The most commonly found bacteria was Staphylococcus intermedius, which was found in 14 out of the 45 wounds (31.11 %). From this study it appears that the first consideration for treatment of infected wounds should be a treatment plan which will have a high efficacy against Staphylococcus spp. However, despite the high prevalence of Staphylococcus spp., our results revealed that they are not present all of the time.

Authors: Bartel Sebastian , Albrecht Juliane , Hruška Vladan , Rybová Kristyna , Ortner Andreas
Published: January 2019

Spatial planning axes are an important instrument of spatial planning to help connect urban areas and ensure the accessibility of rural areas and their development. The planning of such axes can steer population and traffic flows, decisions on the locations of economic developments as well as infrastructures such as cable networks. In this paper, current spatial planning axes and their continuity are analysed regarding their suitability to promote sustainable cross-border European development. Two neighbouring regions are investigated as examples, namely the Regional Planning Authority Oberes Elbtal/Osterzgebirge (Germany, Saxony) and the Ústí nad Labem Region (Czechia). The overarching research question is how transboundary spatial planning axes can be harmonised? This can be broken down into the following three sub-questions: (1) Which differences exist between the Saxon and Czech planning systems? (2) How is the need for harmonisation assessed by planning practitioners? (3) Which transboundary recommendations can be given from a scientific perspective? To answer these research questions, expert interviews were conducted with relevant stakeholders from spatial planning authorities as well as scientific and political institutions.

Background. Colonoscopy is a common performed procedure in Gastroenterology, and it’s widely used for diagnosis, treatment and surveillance of a wide range of conditions and symptoms. Properly performed, it’s generally safe, more accurate than a virtual colonoscopy and well-tolerated by patients. The completion of a colonoscopy is defined by cecal intubation with the visualization of colonic mucosa and distal terminal ileum when it’s possible.

Patients and methods. We reviewed retrospectively all consecutive endoscopies database of the lower digestive tract, done over a period from 2014-2017 in our clinic. The recommended completion based on the latest guidelines ranges from 90-95% completion rate according to the indication.

Results. 11214 consecutive colonoscopies were done. Overall cecal intubation was successful in 9456 procedures (87.3%). If we exclude the interventional procedures (414 procedures), where cecal intubation was not necessary, the main reasons of non-intubation were due to intolerance of the patients (388 patients), followed on the second place by patients with obstructive cancer (299 patients). The presence of diverticulosis, poor preparation for colonoscopy and post-surgical adhesions were significant findings in non-successful procedures.

Conclusions. In normal daily practice, colonoscopy is completed in 88.01% of the procedures but we think that this result will stimulate the efforts to incorporate more quality measures and time in our endoscopy laboratory.

New Technologies in the Recruitment Process
Authors: Sołek-Borowska Celina , Wilczewska Maja
Published: January 2019

Well-conducted recruitment and selection process is extremely important for the organization, permitting in-depth and objective verification of candidates in terms of meeting employer’s expectations and leads to their employment. Up to now, there has been little research on the impact of e-recruitment on the recruitment process as a whole. The present study fills part of this gap by investigating the effect of e-recruitment on the design of the recruitment process. Therefore, the main purpose of the paper is to analyze how new technology has influenced the recruitment process as a whole. The recruitment process will be presented on the example of ItutorGroup. The paper considers the possibilities of including modern technologies in the recruitment and selection strategies of the organization based on a case study method. The case study describes the project of cooperation of the Work Service personnel consultancy with the international organization ItutorGroup. Its selection and recruitment strategy was based on video-recruitment. The findings indicate that e-recruitment transforms the traditional recruitment process into a time- and space-independent, collaborative hiring process. The most significant changes are recorded in the sequence and increased divisibility of main recruitment tasks. For management, the main task is now that of communicating with candidates. Recruitment and selection strategy based on modern technologies requires an experienced and competent team, two unquestionable benefits are: limiting the length of the process in time and possibility to decrease the costs.
Evaluation of Decision Effectiveness Over Time
Authors: Nagy Viktor
Published: January 2019

In this paper, the results of my research are presented that was carried out on a large sample to investigate how people look back at their previous business decisions. After a short literature overview, considering the role of time, the paper deals with the primary research: how people judge their decisions in the short term and in the long run, that is, how confident they are that the right one was chosen applying the available knowledge of facts and conditions connected with or relevant to their situation. Using statistical methods, comparisons were made, for example, based on the respondents’ gender, so it turns out whether gender has an influence on self-confidence or on exactness of judgement. Does the position, that is, the rank matter? Can it be assumed that the farther one gets up the corporate ladder, the more certainty can be observed about their decisions? And what about educational level? Does it influence judgement in a decision? Those who do not regret their decisions after a while, that is, after the original decisions were made, while being in possession of the information available later, can be more successful in business because they made the best decision. Trying to identify such characteristics or factors can be an advantage in the business life.
Quantification of the effect of texture on the magnetization behavior
Authors: Schneider Jürgen , Franke Armin , Stöcker Anett , Kawalla Rudolf
Published: January 2019

For electrical steels there is a need to describe the intensity of the present texture components in the finally processed material as well as after the various processing steps. Preferable texture components like the cube fibre texture will improve the magnetization behaviour. Furthermore, there is interplay between the various processing steps at fabrication on the resulting final texture in the fully processed material. A texture parameter A can be derived from the orientation distribution function (ODF) for arbitrary texture, which describes the texture for each texture components. Taking into account this fact, we used a so-called A-map. The A-map gives the value of A for each point in the Euler space for two fixed values (constants). This A-map may be used to estimate immediately the effect of a different resulting image of texture due to variation of the technology of fabrication of the material. Any increase of the intensity of texture within the area of the ODF, where the A-values are smaller than a certain value, results in improved magnetization behaviour. Within the paper some examples are given.
Influence of lift off on Barkhausen noise parameters of construction steel
Authors: Jančárik Vladimír , Pal’a Jozef
Published: January 2019

The magnetic Barkhausen noise (MBN) measurement technique is a popular magnetic method used for non destructive detection of microstructural changes in ferromagnetic materials. The MBN parameters depend on the gap between the excitation yoke and measured object. To suppress the negative influence of lift off, we tried to find a parameter of the MBN, which could be independent of lift off changing in a practical range. The lift off effect was analysed experimentally on construction steel samples with various levels of carbon content. We found that the amplitude distribution is a promising parameter of MBN in this regard. Measurement results showed that the slope of amplitude distribution was roughly independent of lift off.
Lightness Factors and Exertion Factors Related to its Own Mass of Fiber Reinforced Plastics (FRP) Applied in Composite Aeronautical Structures (Part 2)
Authors: Rodzewicz Mirosław , Lewitowicz Jerzy
Published: January 2019

The paper concerns an application of lightness factors in comparative analysis of strength properties of basic materials being applied in aeronautical structures – in a historical perspective. The use of lightness factors enables effective estimation how lighter will be the structural elements (of the same strength or stiffness) made from different kind of materials : traditional as well as advanced composites. It is quite easy to find the solution to the inverse problem, i.e. to estimate how differ will be stiffness or strength for the same mass of the structural elements. Very particular application of the lightness factors are noted in engineers calculations of composite gliders wing spars, where they appears as the materials constants and as structure loading factors as well. The paper presents some examples of application of the lightness factors in strength analysis of the composite shells applied in the shear webs of the wing spars, and refers to the design recommendations issued by German aviation authority (LBA).

The operation of the water supply network is related to ensuring the reliability of water supply to each customer. The reliability analysis of water supply can be based on reliability indicators of renewable objects such as water pipes. These indicators take into account the characteristics of the system and its components, by function or numerical characteristics. An example of reliability analysis for main and distribution pipes was made. The average renewal time, the average working time without failure and the reliability of network operation were determined.
Clinical Significance of Serum Bilirubin in Behçet's Disease
Authors: Koca Tuba Tülay
Published: January 2019

Background and Objective

Bilirubin (Bb) is the product of the intravascular compartment of catabolic pathway. In a small number of clinical trials, it has been shown that Bb molecules are associated with cardiovascular diseases, diabetes, cancer, autoimmune (lupus, rheumatoid arthritis) diseases and schizophrenia. Behçet's disease is a chronic, multisystemic, inflammatory vasculitis that was first described by Hulusi Behçet in 1937, which affects almost all organs and systems without any known aetiology. Here, we investigated the clinical significance of serum Bb as a biomarker in the patients with Behçet's disease.

Methods

Seventy-one (N = 71) patients with Behcet's diagnosis within the last 1 year were included retrospectively. Control group consisted of 75 subjects with similar age and sex distribution. Serum Bb, indirect Bb, total Bb, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) and erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) data were recorded from the hospital records.

Results

In the Behçet group, direct Bb was significantly lower (P = 0.011), ESR and CRP were significantly higher (P = 0.00). No significant differences were observed in other parameters. In the whole group, total Bb and indirect Bb were negatively correlated with ESR (P = 0.025, P = 0.01). Direct Bb was negatively correlated with CRP (P = 0.002). For the diagnosis of Behçet, direct Bb with a threshold of < 0.14 can be used as a diagnostic test (P = 0.000) with 70% sensitivity, 68% specificity (area under the curve = 0.69; 95% confidence interval 0.59–0.80) in ROC curve analysis.

Conclusion

According to our study, we found that inflammatory markers were high and direct Bb values were low in patients with Behcet's disease. In addition, Bb parameters were negatively associated with acute phase reactants. As a practical biomarker with anti-oxidative properties, the direct Bb can be used to diagnose and clinical follow-up in cases with Behçet's disease.

Introduction: The aim of this study was to determine the predisposing effect of bovine respiratory syncytial virus (BRSV) on Pasteurella spp. infection in naturally-induced pneumonia in cattle by immunohistochemical labelling.

Material and Methods: Lungs of cattle slaughtered in the slaughterhouse were examined macroscopically, and 100 pneumonic samples were taken. The samples were fixed in 10% neutral formalin and embedded in paraffin by routine methods. Sections 5 μm in thickness were cut. The streptavidin-peroxidase method (ABC) was used to stain the sections for immuno-histochemical examination.

Results: BRSV antigens were found in the cytoplasm of epithelial cells of bronchi, bronchioles, and alveoles and within inflammatory cell debris and inflammatory exudate in bronchial lumens. Pasteurella spp. antigens were detected in the cytoplasm of the epithelial cells of bronchi and bronchioles, and in cells in the lumens of bronchi and bronchioles. Eleven cases were positive for only one pathogen (six for BRSV and five for Pasteurella spp.), while 35 cases were positive for 2 pathogens: BRSV plus P. multocida (n = 21) or M. haemolytica (n = 14).

Conclusion: The presence of high levels of BRSV in dual infections indicates that BSRV may be the main pneumonia-inducing agent and an important predisposing factor for the formation of Pasteurella spp. infections in cattle naturally afflicted with pneumonia.

Introduction: The study aimed to isolate thermophilic Campylobacter from chickens raised three rearing methods, determine its antimicrobial susceptibilities, and examine resistance-related genes by PCR.

Material and Methods: Cloacal swabs or intestinal contents were taken in Istanbul, Sakarya, and Izmir provinces. Chickens were from small village-based family-run businesses (n = 70), organically raised (n = 71), and conventionally raised broilers (n = 79). The samples were cultured on modified charcoal cefoperazone desoxycholate (mCCD) agar. Suspect isolates were identified with multiplex PCR (mPCR). As per EUCAST standards, MIC values were derived by broth microdilution for tetracycline, ciprofloxacin, nalidixic acid, kanamycin, gentamicin, and erythromycin in isolates of C. jejuni (n = 98) and C. coli (n = 83).

Results: In C. jejuni, 78.6% tetracycline, 87.8% ciprofloxacin, and 81.6% nalidixic acid resistance was detected, but none was to kanamycin, gentamicin, or erythromycin. In C. coli, 98.8% ciprofloxacin and 63.9% nalidixic acid resistance was detected, whereas resistance to nonquinolones was not observed. C257T (Thr-86-Ile) mutation in the gyrA gene of all phenotypically quinolone-resistant isolates was detected through a mismatch amplification mutation assay PCR (MAMA-PCR). It emerged that all isolates bore the tet (O) resistance gene.

Conclusion: Common tetracycline, nalidixic acid, and ciprofloxacin resistance exists in Campylobacter isolated from chickens raised three rearing methods.
Prediction of Restraint Moments in Precast, Prestressed Structures Made Continuous
Authors: Kytölä Ulla , Laaksonen Anssi
Published: January 2019

This paper studies restraint moments developing in simple-span precast, prestressed beams made continuous. Methods of evaluating restraint moments produced by creep and differential shrinkage are presented. Shrinkage and creep properties of composite structures, beam and deck parts were tested and compared to values defined according to Eurocode models. Finally, the restraint moments were calculated with both material models for the two-span parking deck structure. The study confirmed the findings of previous studies: that the methods that are used overestimate the negative restraint moment produced by differential shrinkage.
Inter- and Intra-Hemispheric EEG Coherence Study in Adults with Neuropsychiatric Disorders

Published: January 2019

Functional connectivity between different regions of the brain in the resting state has been a recent topic of interest in neurophysiological research. EEG coherence happened to be an useful tool for measuring changes in neuro-psycho-physiological functioning which are not detectable by simply measuring amplitude or power spectra.

The aim of our study was to investigate the changes in the EEG coherence in groups of different mental disorders such as: depression, general anxiety disorder, ADHD, Asperger syndrome and headaches, compared to control group. All measures were made in two conditions: eye opened (EO) and eyes closed (EC).

The obtained results show that in EO condition there is a significantly lower coherence for delta waves between analyzed groups. For theta coherence only for Asperger syndrome we found lower coherence compared to control group, ADHD and headaches in parietal region (P3-P4). Obtained results for intrahemispheric coherence have shown that there was significantly lower coherence in both conditions for delta and theta bands in almost all sites for Asperger’s syndrome, and opposite increased intrahemispheric coherence for patients with headaches (for delta band in the anterior regions and for theta band in the posterior regions). ADHD patients expressed lower delta inter-hemispheric coherence in frontal regions, and increased coherence of theta in central regions but increased delta coherence in posterior regions only in EO condition. For depressive and anxiety patients we found decreased intrahemispheric coherence for EO condition for delta brain waves all over the cortex. Concerning the coherence in anxiety patients in our current study we have obtained hypo coherence in centro-parieto-occipital region only for delta in inter-hemispheric coherence and also lower delta coherence through the cortex for intrahemispheric coherence.

Our findings for interhemispheric hyper coherence in subjects with depression specifically for alpha and beta bands were confirmed in other studies.

We suggest that EEG coherence analysis could be a sensitive parameter in the detection of electrophysiological abnormalities in patients with anxiety, depression, ADHD, Asperger syndrome and headaches. These results can confirm the development of QEEG state and trait biomarkers for psychiatric disorders.
Jakub Chlebowski, Rector Magnificus Exultus – A Distinguished Professor of Internal Medicine in Postwar North-East Poland

Jakub Chlebowski (Jakub Frydman) (1905-1969) was a distinguished professor of internal medicine and skillful organizer of health care system in Bialystok region in the North east Poland. He graduated medicine in 1929 and worked at local university in prewar Vilnius. During World War Two, arrested by the Soviets and exiled to Siberian work camps he managed to return to Poland with Kosciuszko Division of Polish Army. Then, he continued to serve as a military and university medical doctor in Cracow and Lodz, finally to take over position of director of Internal Diseases Department in 1951 in Bialystok, holding an office of rector magnificus of Medical University of Bialystok from 1959 to 1962. Chlebowski trained generations of internal medicine specialists, who later became eminent representatives of emerging branches of internal medicine as distinct subspecialties in the field of cardiology, endocrinology and gastroenterology in Bialystok. In course of anti-Semitic campaign during March Events in 1968, he was disposed from the post of director of the university hospital department. Constantly harassed, he immigrated with the family to Israel to die in public traffic accident in 1969. Jakub Frydman, who survived not only hunger of food, but also metaphorical “hunger of humanity” during World War Two, turned out to be as good and useful as daily bread for Polish community after wartime. He was so devoted in this action, that he even changed his surname into Chlebowski (Polish: Chleb=English: Bread). In this way, due to similar experience and experience-shaped mentality, Chlebowski could be counted among medical authorities of the time, the individuals with such a high moral standard as Janusz Korczak (1878 or 1879-1942) or Julian Kramsztyk (1851-1926).
Processes Affecting Sustainable Use of Agricultural Land in Kosovo
Authors: Ramadani Ibrahim , Bytyqi Valbon
Published: January 2019

Agricultural land is facing challenges due to different human activities. Accelerated urbanisation along with explosive economic growth has further worsened the shortage of agricultural land over the last two decades. Kosovo, a country with small areas suitable for agriculture is meeting challenges due to unplanned settlement extension, coal surface mining, parcelisation of properties, etc. This paper consists in an analysis of the agricultural land fund in Kosovo, in quality, production potential and food security for the population, but also the challenges facing Kosovo with this strategic resource. The article analyses three main factors that have made the biggest changes in agricultural land in Kosovo: the effects of settlement extension, coal surface mining and parcelisation in reducing the soil fund. Some of the effects have triggered significant socio-economic processes that have changed the rural environment. Other important risks of agricultural land in Kosovo are: pollution, landfills, frequent floods, etc.
SPAG: A New Measure of Spatial Agglomeration. Theoretical Background and Empirical Examples1
Authors: Kossowski Tomasz , Hauke Jan
Published: January 2019

Kopczewska (2017) proposed a new empirical measure of spatial agglomeration (SPAG) of economic activity based on geolocations of firms. The aim of the paper is to introduce theoretical backgrounds ofSPAG. The measure is a product of two random variables with beta and gamma distributions. The moments of the product are described and estimated for Poland with spatial centroids of LAU2 treated as geolocations of firms for empirical distribution as well as for the set of firms located in a regular region. Another approach toSPAGproperties has its origin in a geometric probability concept. We present the research results on geometric probability, applied toSPAG, as distance probability distributions for a regular region.
