The Relationship Between Energy Consumption and Economic Growth: Evidence From Different Income Country Groups
(Econjournals, 2017) Yaşar, N.
This study analyses the relationship between energy consumption and economic growth for 119 countries during the period of 1970-2015, classified into four groups regarding to the World Bank income ranking. The main motivation of this study is to analyze whether the causal relationship differs between different income groups of countries. For this purpose, panel auto regressive distributed lag boundary approach and Granger causality test were used. The results of the study indicate that the causal relationship between energy use and economic growth differs depending on which income group country belongs to. We conclude that the feedback hypothesis is supported for upper-middle income group in the long run and high-income group, while conservation hypothesis is supported for upper-middle income group in the short run and lower-middle income group in the long run. Finally, neutrality hypothesis is supported for low and lower middle-income groups in the short run. © 2017, Econjournals. All rights reserved.

Testing Stochastic Income Convergence in Seasonal Heterogeneous Panels
(Elsevier, 2010) Guler, Huseyin; Ucar, Nuri
In this paper we introduce a seasonal version of the Solow-Swan growth model and acquire an empirical income convergence equation. We take this equation as a basis to investigate whether income convergence exists in an OECD sample. To do this, we propose the test statistics under various asymptotic properties for some of the seasonal frequencies in the context of nonstationary heterogeneous panels. Critical values and moments of our statistics are generated and their finite sample performances are examined via Monte Carlo simulations. (C) 2009 Elsevier B.V. All rights reserved.

Re-Examining the Threshold Effects in the Inflation-Growth Nexus With Cross-Sectionally Dependent Non-Linear Panel: Evidence From Six Industrialized Economies
(Elsevier Science Bv, 2010) Omay, Tolga; Kan, Elif Oeznur
This paper analyzes the empirical relationship between inflation and output growth using a novel panel data estimation technique, Panel Smooth Transition Regression (PSTR) model, which takes account of the non-linearities in the data. By using a panel data set for 6 industrialized countries that enable us to control for unobserved heterogeneity at both country and time levels, we find that there exists a statistically significant negative relationship between inflation and growth for the inflation rates above the critical threshold level of 2.52%, which is endogenously determined. Furthermore, we also control cross-section dependency by using the CD test modified to non-linear context and remedy cross-section dependency with Seemingly Unrelated Regression Equations through Generalized Least Squares (SURE-GLS) and newly proposed Common Correlated Effects (CCE) estimation techniques. We find that these methods change the critical threshold value slightly. The estimated threshold values from these estimation methods are 3.18% and 2.42%, respectively. (C) 2010 Elsevier B.V.

Türkiye için reaksiyon fonksiyonunun doğrusal olmayan modelle tahmin edilmesi
(Çankaya Üniversitesi, 2010) Omay, Tolga; Hasanov, Mübariz
In this paper we have estimated the monetary reaction function of the Central Bank of the Republic of Turkey. The originality of the paper is that we have used smooth transition functions (STR) that allow for proper modelling of nonlinearities and asymmetries in the relationship between variables under consideration. The estimated models suggest that the backward-looking instead of foreward-looking models best characterize the Central Bank’s reaction function, that is, the Central Bank reacted to past inflation rates rather than to future rates. This finding is in conformity with earlier research. We have found that the main purpose of expansionary policy of the Central Bank is to stabilize output whereas contractionary policies aimed only at reducing the inflation rate. The fact that the Central Bank has disregarded inflation in conducting expansionary policy and focused only on output stabilisation may explain why the Central Bank was not successful in fighting inflation. Besides, neither in expansionary policy regime nor in contractionary policy regime, real exchange rate is not targeted by the Central Bank. Moreover, budget deficit is targeted only in the contractionary policy regime

Stationarity Properties of Renewable Energy Consumption in the Commonwealth of Independent States
(Econjournals, 2020) Yasar, N.
This study investigates the stochastic properties of renewable energy consumption series across 11 Commonwealth of Independent States countries through the period of 1990-2015. For this purpose, along with traditional stationarity analysis recently improved unit root techniques which allows for nonlinear adjustments in the data generating process are used in this paper. Based on our findings we may conclude that, consideration of nonlinearity in regression process causes to more frequent non rejection of the null hypothesis of stationarity. It implies that ignoring possible nonlinearities in time series regression process may lead to some misleading results. Hereby, fluctuations in global energy supply and trade systems influence renewable energy consumption in nonlinear pattern and policy-makers should take it into consideration in terms of proper energy policy implication. © 2019, Econjournals.

The Dynamics of Financial Literacy Within the Framework of Personal Finance: an Analysis Among Turkish University Students
(Academic Journals, 2011) Altintas, Kadir Murat
Poor financial choices could have a number of negative consequences for young people. Financially illiterate graduates might be subject to various financial or judicial enforcements, such as bankruptcy, mortgage crises or financial frauds. In order to protect young adults from the costly consequences of financial illiteracy, the evaluation of financial literacy must be analyzed for transforming them into financially knowledgeable individuals by the help of financial education. The main purpose of this study is to reveal the special characteristics that influence the financial literacy of university students, as well as to evaluate their financial literacy level. Results show that university students do not have adequate knowledge on personal finance and financial management, in other words they need to enhance their financial literacy in order to protect their financial security at the medium and long run. In addition, the most important factors that affect the overall personal financial literacy of university students within the framework of the survey are class rank, age, family's income level, and students' discussion potential with their parents about financial matters.
The Stochastic Futures of the Natural Gas Prices: Russian Federation in Caspian Region
(2014) Yaşar Başkaraağaç, Nermin
This study examines the convergence hypothesis of natural gas price series of Russian Federation and USA using both linear and nonlinear time series techniques Russian Federation and USA during the period of 1991-2011. Although the linear Augmented Dickey Fuller (ADF), Philips Perron (PP), test provide evidence of the existence of a unit root, which means that the series are nonstationary, KPSS test result support the null hypothesis of existence of the stationary series. A nonlinear test as an alternative approach to investigate whether there are nonlinearities in the series is also taken into consideration. KSS, the nonlinear testing procedure provide some supportive evidence of a nonlinear price convergence among the Russian Federation and USA.

Assessment of Criminal Charges Brought Against Teachers
(Nesibe Aydin Education inst, 2020) Okdem, Meltem
The aim of this study was to assess the charges brought against teachers in criminal courts in Turkey. A qualitative research method was used in the study. The study used the document analysis method because it involved the study of legal documents. In order to determine what cases against teachers were brought to trial between 2004 and 2018, charges filed against teachers were obtained via www.kazanci.com and www.LegalBank.com. databases. The themes in the study were determined in accordance with the Turkish Criminal Law as crimes against the person, crimes against the nation and the state, and crimes against society. The study was initiated as a result of the fact that cases of violence in schools have increased rapidly in recent years. One factor in this is offenses committed by teachers, and this situation will cause grave social problems in the future if no measures are taken. It was found that most charges brought against teachers in the criminal courts were cases related to crimes against the person. This was followed by crimes against the nation and state and crimes against society. The curriculum of Faculties of Education should include courses such as human rights, education law, anger control and conflict management to raise teachers' awareness of these issues.

The Relationship Between Foreign Direct Investment and Co 2 Emissions Across a Panel of Countries
(Springer International Publishing, 2018) Yaşar, N.; Telatar, M.E.
This paper analyses the relationship between foreign direct investment inflows and pollution emissions for 139 countries during the period of 1970-2015 and the countries are classified into four groups regarding to the World Bank income ranking. The main motivation of this study is to analyse, whether the causal relationship differs between different income groups. For this purpose, panel ARDL (Auto Regressive Distributed Lag) boundary approach and Granger causality test are used. The results of the study indicate that the causal relationship between FDI (Foreign Direct Investment) and CO 2 emissions differs depending on which income group country belongs to. We conclude that, while there is not statistically significant short-run causality relationship running from FDI to CO 2 emission for high income, upper middle income and low income group countries, the pollution haven hypothesis is supported for lower middle income group countries. © Springer International Publishing AG, part of Springer Nature 2018.
Türkiye’de Banka Sermaye Tamponları, Kredi Büyümesi Ve İş Çevrimleri
(2018) Özşuca, Ekin Ayşe
Bu çalışmada, Türkiye’de faaliyet gösteren bankaların sermaye tamponlarının iş çevrimleri ve kredi büyümesi ile ilişkisi 2002-2017 dönemi için üç aylık veriler kullanılarak incelenmiştir. Tahminler sistem genelleştirilmiş momentler metodu kullanılarak yapılmış ve söz konusu etkilerin bankaların faaliyet türlerine göre farklılık gösterip göstermediği ayrıca test edilmiştir. Elde edile sonuçlara göre, Türkiye’de banka sermaye tamponları iş çevrimlerine karşı döngüsel hareket etmektedir.Ancak bu bulgu yatırım ve kalkınma bankaları için geçerli değildir. Diğer yandan, bankalara özgü özelliklerle ilgili panel regresyon sonuçlarına göre, büyüklük, karlılık ve risk ticari bankaların sermaye tamponlarının anlamlı belirleyicileri olarak ortayaçıkmaktadır. Aynı zamanda, bankacılık sektörünün yapısı ve 2008 küresel finansal krizinin banka sermaye tamponları üzerinde etkili olduğu gözlenmiştir. Sermaye tamponlarının bankaların kredi arzı üzerindeki etkisine dair bulgular ise ters yönlü bir ilişkiye işaret etmektedir. Çalışmanın bulguları, banka sermaye yeterliliğine ilişkin düzenlemeler ile Basel III uzlaşısı kapsamında önerilen ve yakın zamanda uygulamaya koyulan döngüsel sermaye tamponuna dair sonuçları bakımından önem taşımaktadır
Comparative Analysis of Early Studies on Turkish Whistle Language and a Case Study on Test Conditions
(2018) Özaydın, Selma
This paper examines the early studies on Turkish Whistle Language and it argues that they have some controversial results. The study considers these issues need to be discussed and searched again in terms of linguistic and phonetic form. Unfortunately, there are few research studies on Turkish whistle language and most of them were performed nearly fifty years ago despite the fact that this language still has been used in Kuskoy region. Therefore, the findings of these early research studies could give valuable information to start to a new research study on the subject. The first scientific study on Turkish Whistle language was performed by a French scientist R.G. Busnel with his multidisciplinary research team in 1967. Some of this research’s results were published in the book. A Turkish scientist O. Baskan also participated in Busnel’s research group and published a paper on TWsL in 1968. However, some assertions such as people having a tendency to understand the Turkish whistle language with three vowels and three consonants have not been in the research results of R.G. Busnel. In addition, a Turkish scientist D. Aksan in Turkey had performed another research at Kuskoy region with his own team. Their test methods were different from the previous ones. This paper analyzes these research results on a comparative basis and presents the common and conflicted issues to discuss the uncertain points. The comparative evaluation of these past research studies aims to highlight the controversial position of the results on Turkish Whistle Language. In this scope, this paper opens a discussion about the selection of test conditions for an acoustic and linguistic analysis of the Turkish whistle language.

Doğrusal Olmayan Bootstrap Koentegrasyon Testleri: OECD Ülkeleri için Satın Alma Gücü Paritesi Üzerine Bir Uygulama
(2018) Uçar, Nuri; Güler, Hüseyin
Bu çalışmanın doğrusal olmayan panel eşbütünleşme testleri önermesinin dışında ekonometri literatürüne ikinci katkısı ise, doğrudan eşbütünleşme testleri elde etmek yerine, uzun dönem denklemden elde edilen hata tahminlerinin hata düzeltme modellerine uzun dönem değişken olarak eklenip, doğrusal olmayan panel eşbütünleşme testlerini bu modeller üzerinden geliştirecek bootstrap yöntemi öne sürmesidir. Uygulamada, Bootstrap hipotez testleri, Monte Carlo yöntemiyle kritik değerler üretilip, bu kritik değerlere göre değerlendirilmiştir. Bootstrap tahminler için -hem parametre hem de istatistikler- Matlab da kod yazılmıştır. Üretilen eşbütünleşme testleri OECD ülkeleri için, Satın Alma Gücü Paritesi için uzun dönem ilişkinin olup olmadığını test etmek için kullanılmışlardır. Bu uygulamadan elde edilen sonuçlara göre, "diğer ülkelerde" uzun dönem ilişki varken, G7 ülkelerinde ise gözlemlenmemiştir. Satın Alma Gücü Paritesinin iki gurup arasında farklılaşması, ilginç bir sonuçtur. Veri seti oluştururken 2008 krizi dikkate alınarak oluşturulmuştur. Krizin 5 yıl öncesi ve sonrası veri setine dâhil edilmiştir. Buradaki amaç kriz şokunu ortak bir faktör olarak düşünmek ve bu faktörün yatay kesitte bağımlılığa neden olduğunu dikkate alarak bootstrap yaklaşımı ile parametre tahminlerini gerçekleştirmektir. Ayrıca, kriz öncesi dönemi kapsayan veriler içinde Satın Alma Gücü Paritesi araştırılmıştır. Tüm ülkeleri dikkate aldığımızda, kriz dönemini içeren 2003.01-2013.01 dönemi ile kriz öncesi dönem farklılaşmaktadır. Kriz öncesi doğrusal olmayan eşbütünleşme gözükürken, kriz döneminde böyle bir şey söz konusu değildir. Krizin neden olduğu ekonomik şokun ülke ekonomilerinde enflasyon ve döviz kuru verilerinde birlikte kırılmalara (co-breaking) neden olması bu değişkenler arasında doğrusal olmayan eşbütünleşmenin varlığı yönünde beklentiye neden olabilir. Bu doğrusal olmayan yapının "diğer ülkelerde" varlığını göstermesi fakat "G7" ülkelerinde ise eşbütünleşmenin gözlemlenmemesi, bu ülkelerin bu süreçte birbirlerinden ayrıştıklarını da göstermektedir Ekonometri teorisi açısından, bu çalışmada ortaya atılan testlerin istatiksel ve asimptotik özellikleri geliştirilmeye açıktır. Ayrıca, burada önerilen doğrusal olmayan testler uygulama açısından sadece bootstrap yaklaşımı ile değil, diğer yatay kesit bağımlılığını dikkate alan panel veri analizi içerisinde de geliştirilmeye uygundur. Uygulama aşamasında ise, döviz kurundaki değişen varyans problemini dikkate alan test istatistikleri ışığında Satın alma Gücü Paritesi geliştirilebilir.
Okul Yöneticilerinin Yargıtay’a İntikal Eden Hukuka Aykırı Davranışlarının Değerlendirilmesi .
(Pegem Akademi, 2018) Ökdem, Meltem
Toplum halinde yaşayan insanların yerine getirmek zorunda oldukları ödevleri, sorumlulukları ve kullanacakları yetkileri belirten kurallar vardır (Durmuş, 2005). Hukuk toplumun genel yararlarını, bireylerin ve toplumun ortak iyiliğini sağlamak amacıyla yetkili makam tarafından konulmuş ve devlet yaptırımları ile donatılmış kuralların bütünüdür. Hukuk kuralları toplum içinde kişilerin tutum ve davranışlarını düzenler. Arapça kökenli bir sözcük olan ve hak kavramının çoğulu “haklar” anlamına gelen hukuk “toplumsal yaşam içinde kişilerin birbirleriyle, toplumla (ve devletle) olan ilişkilerini düzenleyen kurallarının bütünü” olarak tanımlanabilir (Karaman Kepenekci ve Taşkın, 2017). Hukuk kuralları, toplumsal yaşamda kişilerin birbirleriyle ve devletle olan ilişkilerini düzenleyen maddi yaptırımlı, devlet otoritesi ile desteklenmiş kurallardır (Erkılıç, 2004). Hukuk kurallarının diğer toplumsal davranış kurallarından ayıran en temel özellik, hukuk kurallarının egemen bir otorite tarafından konulmuş olması ve maddi yaptırıma sahip olmasıdır. Hukuk kurallarının temel özellikleri şu şekilde sıralanabilir (Erkılıç, 2004; Gürkan, 1994): • Hukuk kuralları emredici ve yaptırım gücüne sahiptir. • Hukuk kuralları genel, soyut ve nesneldir. • Hukuk kuralları dışa vurulmuş etkinlik ve ilişkileri konu edinir. • Hukuk kuralları emredici ve yaptırım gücüne sahiptir. Hukuk kurallarının özünde emredicilik özelliği vardır. Hukuk kurallarının maddi içeriği ve asıl gücü “emir”dir. Hukuk kurallarına uyulmaması durumunda örgütlü ve sistematik bir biçimde devletin zorlayıcı gücü ile karşılaşılması söz konusudur. Hukuk kuralları diğer toplumsal düzen kurallarına göre daha çok “toplumsal güvence ve garantiye” sahiptirler.

Comparative Performance Analysis of Filtering Methods for Removing Baseline Wander Noise From an Ecg Signal
(World Scientific Publ Co Pte Ltd, 2024) Ozaydin, Selma; Ahmad, Imteyaz
ECG signals play a vital role in the diagnosis of cardiovascular conditions. However, they often suffer from the effects of various noise sources, including baseline wandering, respiratory artifact noise, power line interference and electrode motion artifacts. To overcome these challenges, it is imperative to implement low-frequency signal noise reduction strategies. Such strategies aim to significantly improve the quality of ECG signals, thus promoting more accurate and reliable diagnosis of cardiovascular disorders. This paper conducts a comparative analysis to assess the effectiveness of commonly used filtering and wavelet techniques in reducing Baseline Wander (BW) noise within ECG signals generated by the influence of breathing or electrode movements. It is common to observe the selection and evaluation of only one particular technique in the existing literature. In contrast, this study aims to provide a comprehensive comparative analysis, providing insight into the performance and relative merits of different techniques. Our research uses both filtering and Discrete Wavelet Transform (DWT) techniques in baseline noise removal. In this context, a reference point is established utilizing noise-free signals and a meticulous investigation of the wavelet-based approach that most effectively eliminates the resulting noise is provided. Subsequently, we assess the reference input and output signal via Signal-to-Noise Ratio (SNR) and Kolmogorov-Smirnov statistical test measurements. The most important contribution of this work to the scientific community resides in the comprehensive examination of IIR/FIR-based and wavelet method-based filtering methods capable of yielding the highest SNR levels across various ECG signals with various types of BW noise. Additionally, the effectiveness of the Chebychev-II filter in BW noise removal is highlighted. Our study was conducted using the MATLAB platform and code command lines were shared to facilitate the reproduction of our study by other researchers. It is considered that this study will be an important reference in the selection of effective techniques for removing BW noise within ECG signals.

The Effects of Inflation Uncertainty on Interest Rates: a Nonlinear Approach
(Routledge Journals, Taylor & Francis Ltd, 2010) Hasanov, Muebariz; Omay, Tolga
In this article, we investigate the effects of inflation variability on short-term interest rates within a nonlinear smooth transition regression framework. The test results suggest that only the conditional mean of the inflation is a nonlinear process whereas the conditional variance is time variant but linear. Using the square root of conditional variance as a proxy for inflation risk, we estimate Fisher equation augmented with inflation risk. Although the estimated Fisher equations suggest that inflation risk reduces short-term interest rates, we find that the effects of inflation risk on interest rates are regime-dependent. Particularly, we find that the negative effects of inflation variability on nominal rates are greater in low-inflationary regimes when compared to high-inflationary regimes. On the other hand, it is found that both inflation and inflation uncertainty raise the expected inflation effect.
