The Effects of Real and Nominal Shocks on Real and Nominal Exchange Rates: The Case of Turkey

This paper aims to explain the sources of real exchange rate fluctuations in Turkey. For this purpose, a bivariate SVAR model with the rates of change in the real and in the nominal exchange rates as endogenous variables is specified, and two types of structural shocks are identified as real and nominal shocks in the sprit of two dimensional model of Lastrapes (1992). Using the approach pioneered by Blanchard and Quah (1989), it is assumed that nominal shocks have no permanent effect on the real exchange rate. The results indicate that unlike the previous study of Erlat and Erlat (1998), the contribution of nominal shocks to real exchange rate fluctuations and the contribution of real shocks to nominal exchange rate are not negligible.Real Exchange Rate Fluctuations, Real and Nominal Shocks, Structural Vector Autoregression, Turkey

In this case, we are reporting an 72-year-old man presenting with multi-organ failure due to the this combination and successfully treated with radiofrequency ablation during preexcitated atrial fibrillation

Comparison of Teacher and School Managers` Assignment Policies Between South Korea, Singapore, Japan, Finland and Turkey

In this study, South Korea, Singapore, Japan, Finland and Turkey Countries teachers and school administrators were compared in terms of assignment policies. In this research, a holistic multiple state pattern, which is one of the qualitative research types, was used. The reason for using this method has been examined in accordance with the problem situation of these countries and then compared with each other. The appointment policies of teachers and school administrators should be evaluated along with other processes. South Korea, Singapore, Japan, Finland countries excelled in PISA 2003, 2006, 2009 and 2012 exams. The selection of qualified teachers and school administrators plays an important role in this success of these countries.While choosing candidates for education faculties in these countries, exams measure their teaching skills via central exams. In the process of assigning teachers, central exams are conducted, but institutions again conduct exams that measure their teaching skills. Teaching appeal is a profession in these countries. Because in these countries, teaching has all the features such as respectability, high status, job guarantee and high salary. Teacher salaries in these countries are above the average of OECD countries. In addition, great importance is attached to the in-service training of school administrators and teachers in these countries. The salaries of teachers in Turkey is below the average of OECD countries

Sinus Node Dysfunction as the First Manifestation of Left Ventricular Noncompaction with Multiple Cardiac Abnormalities

AbstractLeft ventricular noncompaction (LVNC) is a genetically heterogenous form of cardiomyopathy which may remain undiagnosed till adulthood due to the late presentation of typical symptoms such as dyspnea, congestion, ventricular arrhythmias and thromboembolism. Symptomatic bradycardia secondary to persistent sinus node dysfunction is very rare. Coexistent cardiac defects are common in children however in adults the disease is usually in isolated form. Here, we present a case of twenty-three year-old female LVNC patient with patent ductus arteriosus, bicuspid aortic valve and persistent sinus node dysfunction who presented with dizziness as the first manifestation of the disease

Big Data Meets Telcos: A Proactive Caching Perspective

Mobile cellular networks are becoming increasingly complex to manage while classical deployment/optimization techniques and current solutions (i.e., cell densification, acquiring more spectrum, etc.) are cost-ineffective and thus seen as stopgaps. This calls for development of novel approaches that leverage recent advances in storage/memory, context-awareness, edge/cloud computing, and falls into framework of big data. However, the big data by itself is yet another complex phenomena to handle and comes with its notorious 4V: velocity, voracity, volume and variety. In this work, we address these issues in optimization of 5G wireless networks via the notion of proactive caching at the base stations. In particular, we investigate the gains of proactive caching in terms of backhaul offloadings and request satisfactions, while tackling the large-amount of available data for content popularity estimation. In order to estimate the content popularity, we first collect users' mobile traffic data from a Turkish telecom operator from several base stations in hours of time interval. Then, an analysis is carried out locally on a big data platform and the gains of proactive caching at the base stations are investigated via numerical simulations. It turns out that several gains are possible depending on the level of available information and storage size. For instance, with 10% of content ratings and 15.4 Gbyte of storage size (87% of total catalog size), proactive caching achieves 100% of request satisfaction and offloads 98% of the backhaul when considering 16 base stations.Comment: 8 pages, 5 figure

Comparison of standard 4-row versus 6-row3-D linear cutter stapler in creation of gastrointestinal system anastomoses: a prospective randomized trial

OBJECTIVE: This prospective study was conducted to compare the clinical outcomes of a 6-row 3-D linear cutter with the standard 4-row linear cutter in patients who underwent elective gastrointestinal surgery anastomosis. METHOD: Patients who underwent elective open gastrointestinal surgery that included stapled anastomosis using a linear cutter (Proximate®, Ethicon Endo-Surgery, Cincinnati, OH) between January 2011 and May 2011 were included in the study. The patients were randomly assigned to two groups according to the linear cutter that was used in the surgery: the standard 4-row cutter (the S group) or the new 6-row cutter (the N group). The groups were compared based on the patient demographic data, the laboratory parameters, the preoperative diagnosis, the surgery performed, the operation time, intra-or postoperative complications, the time to oral tolerance and the length of the hospital stay. RESULTS: The S group included 11 male and nine female patients with a mean age of 65 ± 12 (35-84) years, while the N group included 13 male and eight female patients with a mean age of 62 ±11 (46-79) years (p =0.448, p = 0.443, respectively). Anastomotic line bleeding was observed in eight (40%) patients in the S group and in one (4.7%) patient in the N group (p = 0.006). Dehiscence of the anastomosis line was observed in two (10%) patients in the S group and none in the N group (p =0.131). Anastomotic leakage developed in three (15%) patients in the S group and in one (4.7%) patient in the N group (p = 0.269). The mean hospital stay was 12.65 ± 6.1 days in theS group and 9.52 ± 2.9 days in the N group (p = 0.043). CONCLUSION: The 6-row 3-D linear cutter is a safe and easily applied instrument that can be used to create anastomoses in gastrointestinal surgery. The new stapler provides some usage benefits and is also superior to the standard linear cutter with regard to anastomotic line bleeding

Dental health evaluation of ancient Philadelphia society (Karaman, Turkey)

A total of 53 human skeleton dated to 3rd Century CE were found in the Philadelphia rock tomb excavations and 422 permanent teeth from these findings were used in this study. This study on dental health comprises evaluations of dental wear, caries, abscess, dental calculus and antemortem tooth loss. Caries is found to be 6.9 % in 422 teeth, wear is calculated to be 2.82 on average, the frequency of abscess is 1.67 %, calculus frequency is 18.72% and graded to be 1.96 based on Buikstra and Ubelaker’s scale. The rate for antemortem tooth loss is 16.6 %. Based on these results, the caries, abscess, calculus and antemortem tooth loss are compared with some other populations from the Roman Era. According to this comparison, dental caries, abscess and dental calculus frequencies are lower than other Roman sites, just antemortem tooth loss is a higher degree of prevalence. The results show that the Philadelphia skeletons are found to be healthier regarding oral and dental health except among the Roman sites. Furthermore, the results point out a diet which is based on protein intake rather than a carbohydrate rich diet. This is a preliminary study on Philadelphia society and ongoing excavations will reveal more details about the society in the near future
