Behaviour of emerging stock markets in the global financial meltdown: Evidence from bric-a
(ACADEMIC JOURNALS, 2009) Bora Aktan; Pinar Evrim Mandaci; Baris Serkan Kopurlu; Buelent Ersener; Kopurlu, Baris Serkan; Ersener, Buelent; Mandaci, Pinar Evrim; Aktan, Bora
This paper examines the emerging market indices of Brazil Russia India China and Argentina (BRICA) and investigates the linkages among the stock markets of the BRICA countries and their relations with the US market. We employ the vector auto regression (VAR) techniques to model the interdependencies and Granger causality test to find evidence of a short-run relationship between these markets. In addition we employ the Impulse Response test to evaluate the persistence of shocks by using daily data from 1(st) January 2002 to 18(th) February 2009. Our findings show that the US market has a significant effect on all BRICA countries in the same trading day. The most integrated markets to the BRICA countries are Russia and Brazil, the least integrated ones are China and Argentina. The Granger causality test supports our VAR calculations and shows that Russia influences all other countries and Brazil affects Argentina Russia and India. However China only affects Argentina and Russia. Impulse response test shows that all countries respond to an anticipated shock immediately and recover in nearly five or six days.

Comparison of methods for allocation of service departments' costs to operating departments: A Monte Carlo simulation
(ACADEMIC JOURNALS, 2010) Suleyman Yukcu; Hakan Ozkaya; Ozkaya, Hakan; Yukcu, Suleyman
In this paper, the performance of widely used methods for allocation of multiple service departments costs to operating departments namely direct method and two different applications of step-down method were compared by using the criteria of deviation of their results from those of reciprocal method which is posited as the most accurate method for allocation. Moreover the conditions under which each method yielded the best results were presented. Our dataset included randomly obtained 10000 observations with different percentages of service provided by service departments and different cost figures. Results indicated that the application of step-down method which considered percentage of service provided as the base for ranking service departments yielded least deviation from results of reciprocal method on average and yielded the best results with highest probability and the worst results with the least probability thus provided more accurate results than competing methods.

Hash-based document extraction in corporate mobile devices using ontological architectures
(ACADEMIC JOURNALS, 2011) Tuncay Ercan
Due to the rapid technological advances in mobile and wireless networking devices personal computing has moved towards into ad hoc and pervasive environments. Today the dynamic nature of mobile applications and services have integrated them far more in end-users' lives. Organizations need an effective way of handling their information system for their employees and customers. Mobile devices such as notebook computers Personal Digital Assistants (PDAs) smart phones owned by the corporate and individual users should be adaptable into the existing business environment. In this paper we present a hash-based framework namely SCDE (Shared Corporate Data Extraction) using the current ontological architectures of the corporate domains. This study presents a semantic hashing mechanism formulating an effective search query and assists users with an easier query builder interface. It also extends the features of the user preferences sub-ontology and provides an effective performance against well-known weaknesses of mobile devices. Our model also supports future plans of users' interaction with semantic structures knowledge sharing and new business opportunities for Corporate Information Management Systems.
