Relationships between exchange rate regime, real exchange rate volatility and currency structure of government bonds in emerging markets
Authors: Dudzich Viktar 
Published: May 2020

Abstract
Public foreign currency borrowing is a common problem of emerging markets. Scholars named it the original sin of foreign debt. It has a proven negative influence on economic growth and development, undermining financial stability, and increasing the probability of monetary crises. The roots of the original sin often lay in emerging markets’ institutional underdevelopment, with low-quality monetary policy, inappropriate exchange rate regime choice, and exchange rate mismanagement being stated among the most important causes. This paper evaluates the influence of the exchange rate policy on the emission of foreign currency sovereign bonds in emerging markets. The relationship is estimated using panel data and GMM approach, with exchange rate regime type (both de jure and de facto) and real exchange rate volatility serving as explanatory variables. The findings reveal that fixed exchange rate regime and high real exchange rate volatility is promoting the foreign currency borrowing. Thus countries that want to reduce the burden of the original sin should lean towards a more flexible exchange rate policy while maintaining their real exchange rate stable.
Determinants of private investments in Turkey: Examining the role of democracy
Authors: Akçay Selçuk , Karasoy Alper 
Published: May 2020

Abstract
This study investigates the determinants of private sector investments in Turkey with a focus on democracy. Using the Autoregressive Distributed Lag (ARDL) bounds testing approach and two different democracy indices along with the other determinants of private investment, we estimated a private investment function for the 1975-2014 period. Our main finding is that democracy has a profound positive impact on private investment. Moreover, the results show that: (i) public investment is a substitute to private investment; (ii) macroeconomic instability dissuades private investment; (iii) real interest is a serious impediment to private investment; (iv) financial development and GDP growth rate stimulate private investment.
Barrett’s Esophagus in Romania: what do we know?
Authors: Piloiu Claudia , Dumitrascu Dan L. 
Published: May 2020

Abstract

Background and aims. The incidence of Barrett’s Esophagus (BE) is increasing worldwide, thus diagnosis is becoming a major key of interest in preventing esophageal adenocarcinoma. Because the status of BE in Romania is unclear, we performed a narrative review to comprehensively evaluate all published articles on BE from Romania.

Methods. We conducted a systematic literature search of PubMed data base and of all Romanian medical journals. The abstracts and the titles of the identified studies were reviewed to exclude the studies that did not answer the search question. In addition we performed a manual search to identify articles on this topic published earlier in local journals or not indexed on internet.

Results. A total of 17 articles were found. 8 studies and 9 reviews were identified, with a total of 8,829 participants enrolled. The results showed that the median age ranges between 54–59 years, with a predominance for male sex, the main risk factors, such as gastroesophageal reflux disease, obesity, smoking, hiatal hernia, are also present in Romania and infection with H. pylori has a protective effect. The diagnosis of Barrett’s esophagus in Romania is established in agreement with international guidelines.

Conclusions. There are not many publications on BE in Romania. However the data in this country are similar to those reported in other countries. The management is carried out according to standard guidelines. Diagnosing BE relies on endoscopic techniques and classification systems. Risk factors such as gastroesophageal reflux, hiatal hernia, obesity and Helicobacter pylori are considered in Romanian articles. More studies are welcome on this matter in our country.
Stress cardiomyopathy misinterpreted as ST-segment elevation myocardial infarction in a patient with aneurysmal subarachnoid hemorrhage: a case report
Authors: Enache Iulian , Radu Răzvan Alexandru , Terecoasă Elena Oana , Dorobăţ Bogdan , Tiu Cristina 
Published: May 2020

Abstract
Cardiac abnormalities are frequently reported in acute subarachnoid hemorrhage (SAH) patients. However, frank ST-elevation and myocardial dysfunction mimicking acute coronary syndrome is a rare occurrence. Systemic and local catecholamine release mediate myocardial injury and may explain raised troponin levels, concordant regional wall motion abnormalities and systolic dysfunction. These findings can pose a significant problem in the acute setting where “time-is-muscle” paradigm can rush clinicians towards a “rule-in” diagnosis of acute myocardial infarction.
We present the case of a 60-year-old male who arrived at a regional emergency department with loss of consciousness, chest pain and headache. His ECG showed ST-elevation in precordial leads with corresponding region wall motion abnormalities and dynamically elevated troponin levels which supported a diagnosis of acute myocardial infarction. Percutaneous coronary intervention was attempted but found no hemodynamically significant lesions and the patient was managed conservatively with antithrombotic treatment. Further work-up for his headache led to the diagnosis of aneurysmal SAH and subsequent endovascular coiling. The patient was discharged with a good clinical outcome. We discuss the potential catastrophic consequences of interpreting neurologic myocardial stunning as STEMI. Use of potent antithrombotic therapies, like bridging thrombolysis, in this setting can lead to dismal consequences. Clinical history should still be carefully obtained in the acute setting in this era of sensitive biomarkers.

Abstract
Field, mineralogical and petrochemical studies of the Precambrian Basement Complex rocks around Akungba-Akoko were carried out with the aim of determining their petrology, petrochemical characteristics and petrogenesis. The petrology of Akungba-Akoko area comprises migmatite, granite gneiss and biotite gneiss intruded by biotite granite, charnockite and minor felsic and basic rocks. Seventeen representative samples of the granite gneiss, biotite gneiss, biotite granite and charnockite were collected during field geological mapping of the area for petrographic and geochemical analyses. Modal mineralogy revealed that the granite gneiss, biotite gneiss and granite have assemblages of quartz + feldspar + mica + hornblende + opaques and are granitic in composition. The charnockite is characterized by anhydrous mineral assemblage of quartz + feldspar + biotite + hornblende + pyroxene + opaques. Petrochemical data of the rocks revealed that they are moderately to highly enrich in SiO2, sub-alkaline, peraluminous, magnesian to ferroan and calcic and have K/Rb < 283. The geochemical characteristics and discrimination of the rocks indicated that the granite gneiss and biotite gneiss are orthogneisses formed by metamorphism of igneous protoliths of granitic composition and the biotite granite and charnockite are of igneous/magmatic origin. The biotite granite, charnockite and the igneous protoliths of the biotite gneiss are I-type granitoids formed from crustal igneous-sourced melt(s), while the igneous protoliths of the granite gneiss is a S-type granitoid probably derived from shallow crustal or sedimentary-sourced melt(s). Tectonic discrimination of the rocks indicated that they were formed during a phase of magmatic activity related to collision and subduction.

Abstract

Aim: The aim of this study is to identify correlations between total antioxidant status values of mothers and their infants and compare these values in accordance to the presence or absence of intrauterine growth restriction.

Material and methods: This is a prospective, comparative study performed over a period of 3 years on a number of 52 infants and their mothers. Thirty-six of them had intrauterine growth restriction and 16 were appropriate for their gestational age and were used for comparative purposes. General information regarding the mother, infant and pregnancy were recorded. In addition, total antioxidant status was assessed from blood samples, taken right before delivery from mothers and from the cord blood in infants.

Results: We found significant differences between total antioxidant status both between mothers and neonates with IUGR (intrauterine growth restriction) versus without IUGR (p=0.018, and p<0.001, respectively). In addition, in both groups, there was a significant direct correlation between maternal and neonatal values of serum total antioxidant status (TAS) (p<0.001).
In conclusion, we can say that TAS values, as an important marker of the oxidative status of patients, are correlated with the presence of IUGR and values recorded from blood samples of the mother may be predictive for the oxidative status of the infant, thus of IUGR.

Published: May 2020

Abstract
To date it is unknown if there is a predisposition to sepsis. In this respect, genetic studies have been conducted with the aim to find gene variants which can point out a higher predisposition to developing sepsis. The primary objective of this study is to highlight whether the genetic polymorphism of Angiopoietin-2 gene (ANG2-35G>C) is present mainly in septic patients. As secondary objectives we aimed to evaluate if there are any associations between ANG2-35G>C polymorphism and the severity scores Acute Physiology and Chronic Health Evaluation II (APACHE II) and Simplified Acute Physiology Score (SAPS) as well as routine tests in septic patients such as C reactive protein (CRP), procalcitonin (PCT). We enrolled adult patients admitted to the Intensive Care Unit (ICU). After admission to the ICU and the diagnosis of sepsis, blood samples were collected and the severity scores: APACHE II, SAPS were calculated on the first day of ICU admission. We recorded the following from the blood samples: CRP, PCT, angiopoietine2 (Ang-2). We performed several one-way ANOVA tests to determine any significant mean difference of the analyzed variables. We observed that variant genotypes of ANG2-35G>C gene polymorphism are significantly related to CRP, aspect which increases this biomarker credibility compared with others (i.e., PCT), in septic patients. ANG2-35G>C gene polymorphism is associated with severity scores, APACHE II, and SAPS in sepsis.

Published: May 2020

Abstract
In the recent years, a lot of research has been carried out in the field of nanofluid based solar collector, leading towards the enhancement of working efficiency even at low atmospheric temperature or at low sunlight levels regions of the world. The present review pertains to the research progress related to the performance execution of solar collector using nanofluid. It is observed that the thermal energy storage system (TES), using solar collector, is a useful device for storing sensible and latent heat in a unit volume. Nanofluid plays an important role in various thermal applications such as heat exchanger, solar power generation, automotive industries, electronic cooling system, etc. The nanoparticles find the use in various industrial applications because of its properties, such as thermal, mechanical, optical and electrical. Most of the investigations carried out earlier on the applications of nanofluid in solar energy are related to their uses in the solar collector and thermal storage system. The parabolic solar collector using nanofluid is still a challenge. This article presents an exhaustive review of thermal storage system using nanofluid based solar collector and a scope of using nanofluid based solar collector for performance enhancement.
Numerical Comparison of Thermal Behaviour Between Ventilated Facades
Authors: Schabowicz Krzysztof , Zawiślak Łukasz 
Published: May 2020

Abstract
Increasingly high demands on environmental protection are intensifying the development of sustainable construction. Ventilated facades can provide an energy-efficient alternative to standard facades, that is, external thermal insulation composite systems (ETICS). The article compares standard facades, which was a reference, to ventilated facades in two variants: closed joints and open joints. The comparison was made by means of numerical simulations of computational fluid dynamic (CFD), under conditions of high outside temperature and high sunshine. The results showed great benefits of using ventilated facades in such external climate conditions. It was also observed that the selection of the variant of ventilated facade in the system of close or open joints has minimal influence on thermal efficiency of the whole partition.
Three Notes on the Method of Analysis and Synthesis in its Ancient and (Arabic) Medieval Contexts
Authors: Moubarez Hany 
Published: May 2020

Abstract
Most historians and philosophers of philosophy and history of mathematics hold one interpretation or the other of the nature of method of analysis and synthesis in itself and in its historical development. In this paper, I am trying to prove – through three points – that, in fact, there were two understandings of that method in Greek mathematics and philosophy, and which were reflected in Arabic mathematical science and philosophy; this reflection is considered as proof also of this double nature of that method. Thus, we have to rethink the nature of Arabic philosophy systems.

Published: May 2020

Abstract

Introduction
Migraine is associated with significant morbidity and a significantly negative impact on the quality of life. A better understanding of the economic impact of migraine is becoming increasingly important. This paper aims to shed light on absenteeism and presenteeism costs of migraine in Slovenia.

Methods
We use the administrative national-level database on sick leave due to migraine for 2016. The absenteeism cost estimate is based on the number of patients with migraine on physician-determined sick leave and average daily labour costs. We calculate productivity costs from a social perspective regardless of who incurs them. Data from the national registry on sick leave are coupled with data from a web-based self-reported survey to also include the cost of presenteeism. MIDAS and WPAI presenteeism items were used and several different scenarios were designed to assess presenteeism costs.

Results
We estimated annual absenteeism costs per absentee due to migraine at the amount of EUR 531 in 2016 using the NIPH’s administrative data on sick leave. Annual absenteeism costs per absentee due to migraine based on self-reported data amounted to EUR 626. The estimated annual presenteeism costs per patient range from EUR 344 – 900.

Conclusion
Estimating the economic burden of a disease is becoming increasingly important. This paper is an insight into the absenteeism and presenteeism costs of migraine in Slovenia.

Abstract

Introduction
Evidence on long-term effectiveness and cost effectiveness of treatment sequences for multiple myeloma (MM) is sparse. We used published data and country-specific data to assess the cost effectiveness of four-line treatment sequences for elderly transplant-ineligible patients with MM in Serbia.

Method
We developed a Markov cohort model to compare long-term effectiveness and cost effectiveness of five sequential MM treatment alternatives from the perspective of the national healthcare provider. Effectiveness parameters on progression, mortality and adverse events were extracted from published clinical trials. Costs were based on price lists of the National Health Insurance Fund. We compared life expectancy, costs, and incremental cost-effectiveness ratios among alternative courses of action. The model was analyzed over a lifelong time horizon applying a 3% annual discount rate for effectiveness outcomes and costs. Robustness of the model was tested in multiple deterministic sensitivity analyses.

Results
The sequences were defined by the frontline treatment: MPT (melphalan-prednisone-thalidomide), MPV (melphalanprednisone-bortezomib), CTD (cyclophosphamide-thalidomide-dexamethasone), VCD (bortezomib-cyclophosphamidedexamethasone) and BP (bendamustine-prednisone). MPV sequence resulted in the highest remaining life expectancy (4.76 life years). Cost-effectiveness analysis resulted in three non-dominated strategies: MPT, VCD, and MPV sequences, with an incremental cost-effectiveness ratio of EUR 35,300 per life-year gained (LYG) for VCD and EUR 47,200/LYG for MPV relative to MPT.

Conclusion
MPV sequence was the most effective in terms of life expectancy for elderly transplant-ineligible MM patients in Serbia. Bortezomib-based strategies would be recommended for the frontline treatment of patients with MM in Serbia if the willingness-to-pay threshold is around EUR 35,000-60,000/LYG.
Physicians’ Attitudes toward Adolescent Confidentiality Services: Scale Development and Validation
Authors: Jeremić Stojković Vida , Cvjetković Smiljana , Matejić Bojana 
Published: May 2020

Abstract

Introduction
Confidentiality is one of the oldest ethical principles in healthcare. However, confidentiality in adolescent healthcare is not a universally-accepted doctrine among scholars. The ethical acceptability of confidential services in adolescents’ healthcare is based on perceptions of adolescent maturity and an appreciation of its importance to adolescents’ access and utilization of healthcare services. Despite legal policies that promote adolescents’ rights, physicians’ attitudes toward adolescent confidentiality can be a determining factor in their ultimate decision to protect adolescents’ confidentiality.

Method
A new Attitude towards Adolescent Confidentiality Scale was developed based on the results of a qualitative interview study. This new instrument was administered to a sample of 152 physicians working at school pediatric and gynecology departments in 13 primary healthcare institutions in Belgrade. Principal component analysis was applied to determine the main components of the scale. Reliability was assessed by calculating Cronbach alpha and mean inter-item correlations.

Results
Psychometric analysis of the final 19-item version of the scale showed a high level of reliability (Cronbach alpha of 0.83). Principal component analysis showed four components, which present subscales of the instrument: Confidentiality in clinical situation, Iimportance of confidentiality, Adolescent maturity, and Communication with parents.

Conclusions
The instrument showed satisfactory levels of reliability and validity. The results of the scale dissemination may be a valuable tool for needs assessment for future educational interventions and training programs that will raise physicians’ awareness of the importance of adolescent confidentiality.

Published: May 2020

Abstract
The main objective of the research is to study the perception of students in accounting profile within the "AurelVlaicu" University of Arad in comparison with the employers’ perception of the hard and soft skills needed in view of the accounting graduates’ access on the labour force market. The target group has been asked to express its opinion on the skills required to candidates to access the jobs in order to penetrate the labour force market in the field of accounting. In order to achieve this objective, an empirical study based on a cross-cutting descriptive research has been carried out, the method chosen is the survey based on a questionnaire. The target group consists of 250 students majoring in accounting within "AurelVlaicu" University of Arad, as well as from 300 professional accountants who are members of CECCAR (The Body o Experts and Chartered Accountants of Romania). The case study concluded that a large part of the interviewed accountants have considered that employers would be increasingly interested in hiring young graduates in accounting that hold strong soft skills, being also willing to subsequently invest in trainings to develop their hard skills that they need daily in the chosen job. In order to succeed and perform in the field in which they will work, accounting students (future accounting professionals) must hold a set of powerful soft skills to complete the hard skills acquired and tested during the academic studies. The target group interviewed in the case study considers it would be useful the accounting students to participate in internships, scientific sessions, Erasmus scholarships, voluntary actions, Work and Travel Programs, teambuilding programs, national and international projects, summer schools, student scientific clubs to develop hard and soft skills during the university studies. In order to generate sustainable organisational success, future professionals who will be working in the field of accountancy will have to possess both hard skills and soft skills to be able to contribute in this way to the success of the organization they will be part of and the accounting profession will gain.
Scoring Model for the Detection of Fake News
Authors: Pop Mihai-Ionuț 
Published: May 2020

Abstract
Misinformation has always existed and has been promoted by groups of individuals, who share the same interests, in order to reach ideological, political or financial goals. In recent years, the emergence of the Internet and social platforms has opened a new and larger dimension in the dissemination of false content and information. With the help of these new technological means, the process of manipulation has evolved and reached a new level which materialized in the concept of fake news. The negative effects associated with this phenomenon have aroused interest among specialists, who are striving to find efficient instruments in order to combat the dissemination of fake information.
In this context, I have developed a scoring model for the detection of fake news, which aims to combat the spreading of false information regarding specialized economic sectors, such as the energy field. Moreover, the model could also be implemented as an important instrument in the fighting against this negative phenomenon that can affect the way public figures, institutions, companies or industries are being perceived by the public opinion.
