    Wavelet Transform and Artificial Neutral Network for the Quantitative Resolution of Ternary Mixtures
    (Revista Chimie Srl, 2006) Dinc, Erdal; Baleanu, Dumitru; Baleanu, Dumitru; Tas, Aysegul; Matematik
    Two different approaches continuous wavelet transform (CWT) and artificial neural network (ANN) were successfully applied to the quantitative resolution of ternary mixtures of paracetamol (PAR), metamizol (MET) and caffeine (CA) having strongly overlapping spectra. First approach is based on the use of CWT signals of the ratio spectra of three active compounds in samples. Various CWT families were tested for the extraction of cardinal information and small noise condition and higher peaks of the original spectra. In this paper, three methods: Mexican hat function (MEX) (a = 70), reverse biorthogonal (RBIO3.5) (a = 100) and biorthogonal (BIOR2.4) (a = 90) were found suitable for determination of three active compounds and their signal analysis. ANN, as a multivariate numerical method, was used for the quantitative resolution of the same ternary mixtures. The performance of CWT and ANN approaches was validated by analyzing the synthetic mixtures of PAR, MET and CA compounds. In addition, the standard addition technique was also used for the same purpose. The experimental results provided by CWT technique were compared with each other and those obtained by ANN method and a coincidence was observed for all the obtained results.

    (EuroJournals, Inc., 2009) Belbaǧ, S.; Tarım, Şule; Çimen, M.; Tarim, S.; Taş, A.; Çankaya Meslek Yüksekokulu
    The purpose of this study is to draw a detailed picture of the current situation with regard to supply chain inventory planning systems used in the Turkish retail sector. During the study, companies developing enterprise resource planning (ERP) software were contacted and asked questions oriented to reveal the contribution of current enterprise resource planning software in supply chain management and the opportunities they offer to users in terms of inventory planning. Interviews were made using one or more of the interview techniques of electronic mail, telephone or one-to-one interview. Through these interviews, it was attempted to determine the estimation and planning capabilities of the existing ERP software and draw an inventory of the solutions currently offered to users that will meet the varying demands of the companies operating in the retail sector. In addition, a comparison of the ERP products of national and foreign software companies producing solutions with various functionalities for the retail sector is made along with an evaluation in view of enterprise management. © EuroJournals Publishing, Inc. 2009.

    The Effect of Knowledge Economy on Organizational Environments: Do the Governance Mechanisms Differ According To Institutional and Technical Environments
    (int Business information Management Assoc-ibima, 2009) Sener, Irge; Şener, İrge; İşletme
    Technological developments result in important changes for organizations and their environment. The most remarkable change in the organizational field is the widespread usage of Internet, a new information and communication technology (ICT). The changes depending on Internet, affect organizational structures, since they are designed compatible to the communication needs dependent on the technology. In some cases, however, the communication technologies can be developed in consistence with the organizational structure. This indicates that, when ICTs are taken into consideration, it occurs that there is no clear distinction between technical and institutional organizational environments. The ICTs dependent on Internet is both a legitimacy source for the organizations and an efficiency tool. Accordingly, in this study it is considered that the technical and institutional environments are interpenetrated and different types of governance mechanisms result due to the varying effects of the environmental pressures. Testable propositions are developed for different types of environments.

    Türkiye''de Kırsal Alanda Yoksulluğun Azaltılmasında Hayvancılığın Ve Hayvansal Ürün İşleyen Kobilerin Rolü
    (2004) Gülçubuk, Bülent; Aluftekin, Nilay
    1980’li yıllardan sonra uygulanan ekonomi politikalarından hayvancılık önemli ölçüde etkilenmiştir. Politikalar özellikle küçükbaş hayvancılık ile uğraşanları etkilemiştir. Çünkü, bunlar Türkiye’nin çoğunlukla az gelişmiş veya geri kalmış yörelerinde yaşamakta olup, alternatif gelir kaynakları da oldukça sınırlıdır. Küçükbaş hayvancılıkla uğraşanlar tarım kesiminin en dağınık ve örgütsüz grubunu oluşturmaktadır. Bu grup, ekonomik ve toplumsal değişim süreçleri sonunda giderek daha da yoksullaşmaktadır. Türkiye’de başta küçükbaş olmak üzere hayvan sayılarındaki sürekli azalışlar da bunu doğrulamaktadır. Nitekim, 1980-2001 yılları arasında koyun sayısında %44.5, kıl keçisi sayısında %56.1, tiftik keçisi sayısında %90.4 ve sığır sayısında %33.6 oranında azalma olmuştur. Sonuçta, önemli bir nüfus grubu giderek yoksullaşmakta veya kentlere göç ederek yeni yaşam maceralarına sürüklenmektedir.Türkiye’de küçükbaş hayvan varlığının en fazla olduğu Doğu Anadolu Bölgesi ile Güneydoğu Anadolu Bölgelerinde “yoksul birey oranı” sırasıyla %25.0 ve %24.0’dür. Kırsal ekonomik yapının önemli bir parçası durumunda olan hayvancılık sektörü, özellikle bu sektörü meydana getiren işletmelerin ölçekleri, yapıları, üretim süreçleri ve kuruluş yerleri açısından kendi bünyelerinde bir çok farklılıklar göstermektedir. Avrupa Birliği’ne girme çabasında olan Türkiye’de, hayvancılık sektöründe faaliyet gösteren küçük ve orta ölçekli işletmelerin (KOBİ) daha aktif, verimli ve üretken hale gelmesi kırsal kalkınma ve özellikle de yoksulluğun azaltılması açısından önem taşımaktadır.Bu makalede, yoksulluğun tanımı, nitelikleri ve bölgesel görünümü kısaca verildikten sonra kırsal alanda yoksulluk konusu ele alınmış ve kırsal alanda yoksulluğun azaltılmasında hayvancılığın ve hayvansal ürün işleyen KOBİ’lerin rolü tartışılmıştır. Ayrıca, kırsal alanda yoksulluğun azaltılması için hayvancılık politikaları konusunda stratejiler geliştirilmiştir.

    Towards Predicting Financial Information Manipulation
    (2007) Aktaş, Ramazan; Alp, Ali; Doğanay, Mehmet Mete
    Manipulation is one of the important issues in securities markets because manipulative actions send false signals to the investors and make them buy or sell securities they otherwise would not buy or sell. There are different types of manipulations that can deceive investors. One type of manipulation is financial information manipulation. Manipulators, who use this type of manipulation, distort information in the financial statements in order to give false information about the prospects of the issuing firms. This paper attempts to predict financial information manipulation by using the multivariate statistical techniques and neural networks. A number of financial ratios are used as explanatory variables. The multivariate statistical techniques used are discriminant analysis, logistics regression (logit), and probit. Unlike other studies, the present study takes multicollinearity between financial ratios into account and conclude that the estimated multivariate statistical models rather than the neural networks can be used as early warning systems to detect possible financial information manipulations.

    Predicting Financial Failure of the Turkish Banks
    (World Scientific Publ Co Pte Ltd, 2006) Doganay, M. Mete; Ceylan, Nildag Basak; Aktas, Ramazan; Akta, Ramazan
    Banks are the most important financial institutions in Turkey because other financial institutions are not developed efficiently yet. Turkish banks experienced financial difficulties and a substantial amount of banks failed in the past. This event urged the government to initiate measures to prevent banks from getting into financial difficulties. As a result of these measures, Turkish banking system currently seems to be very attractive for the foreign investors willing to invest in this sector. One of the main concerns of the foreign investors is a possibility of a new banking crisis although it is very remote at this time. The purpose of this study is to develop early warning systems predicting the financial failure at least three years ahead of financial date. A number of multivariate statistical models such as multiple regression, discriminant analysis, logit, probit are used. We found that the most appropriate model is logit. The significant variables obtained from the models explain very well the causes of the bank failures. Our models can be used to assist interested parties to predict the probability of financial failure of Turkish banks.
