Financial time series including high frequency structures like jumps, spikes and stochastic volatility are usually modeled in an ad-hoc manner by stochastic differential equations together with Levy processes. Estimating the parameters and determining the jump size distributions do not have a precise and universally accepted method. Under these circumstances, complexities and confusions usually arise. This book, approaches to this issue from a very different angle through introducing an autocorrelation one process together with finite number of Fourier series terms. Introduction of Fourier series to estimate the dynamics of the process is not done in an ad-hoc manner or as done before in dealing with seasonality. Here the moving average is transformed to a “moving and fluctuating” average by the help of Fourier series. Instead of adding jump structures to the model which makes the parameter estimation quite cumbersome, our model in discrete time can easily be transformed to a well-known mean reverting continuous time process. Moreover, our alternative model turned out to be a quite powerful and accurate forecasting technique.

Kurumsallaşma kavramı, büyük ve büyümekte olan işletmelerin, kişilere (işletme sahibi, patron) bağlı olmadan, örgüt içerisinde kurallara dayalı bir sistem kurularak faaliyetlerini devam ettirmesi ve gelecek kuşaklara da aktarması açısından oldukça önem arz etmektedir. Bu duruma istinaden, her yıl ağırladığı turist sayısı bakımından dünyada ilk on ülke içinde yer alan ve Akdeniz çanağının en kaliteli otellerine sahip olan Türkiye’deki otel işletmelerinin daha kurumsal bir anlayışla idare edilmesi ve faaliyetlerini sürdürmesi kaçınılmaz bir zorunluluktur. Bu çalışma, turizm sektörünün üç önemli sacayağından (tripot) biri niteliğinde olan otel işletmelerinde çalışan işgörenlerin kurumsallaşma algı düzeylerini tespit etmek ve kurumsallaşma algılarının farklı değişkenler açısından farklılaşıp farklılaşmadığını tespit etmek amacıyla yapılmıştır.

International Security and Terrorism analyses contemporary issues in international orders. This book assesses the terrorist attacks which were organised in African, Asian, European and Middle Eastern countries in detail. Therefore, it provides a comprehensive understanding for academics, practitioners, researchers, students and readers who are interested in international security and terrorism. It utilises data about casualties, attack types and countries that exposed terrorism. The book critically examines terrorism, traditional counter-terrorism tactics, securitisation and the new terrorism. It focuses on religiously-motivated terrorist groups, e.g. al-Qaeda, ISIS, Boko Haram and al-Shabaab.
