An Analysis of the Changing Modus Operandi of Terrorist Attacks in Europe

There is a sharp increase in both the number of incidents and the deaths caused by different types of attacks in Europe recently. The assailants claimed these attacks either on behalf of Islamic State in Iraq and Levant (ISIL) or as lone wolves with no direct affiliation to the ISIL. However, there has been some change in the way some of the attacks were carried out. Also, there was a shift in their target selection. Security experts and authorities have indicated significant factors contributing to this development. This paper examines the apparent alarming trend in the change of terrorist modus operandi in Europe. The authors gathered a dataset from various open sources, primarily from Global Terrorism Database (GTD). The findings reveal that terrorists’ modus operandi -- techniques, tactics, and procedures (TTP) -- has been influenced by international events and conflicts

A New Approach to a Theorem of Eng

The main aim of this work is to give a case-free algebraic proof for a theorem of Eng on the Poincar\'e polynomial of parabolic quotients of finite Coxeter groups evaluated at -1

An Inversion Statistic on the Hyperoctahedral Group

In this paper, we introduce an inversion statistic on the hyperoctahedral group $B_n$ by using an decomposition of a positive root system of this reflection group. Then we prove some combinatorial properties for the inversion statistic. We establish an enumeration system on the group $B_n$ and give an efficient method to uniquely derive any group element known its enumeration order with the help of the inversion table. In addition, we prove that the \textit{flag-major index} is equi-distributed with this inversion statistic on $B_n$

EVALUATION OF EFFECTIVENESS OF VITAMIN TEACHER PORTAL

Distance education systems have been developing rapidly in the field of education. Since the beginning of FATIH (Opportunities to Increase and Technology to Improve Motion) Project applications, educational softwares and the concept of e-learning have been important concerns. Besides the lack or insufficiency of softwares for tablets or smart boards, the education content websites which already exist have been struggling to take part in this field. As a result, it is inevitable that there has been a competition between government supported applications and private sector. Vitamin Teacher Portal is an application that serves as a teacher training program. It is a distance education website designed for teachers to improve their both personal and professional skills. It includes live courses, forum, shares, teachers’ resources and educational videos. It is a synchronous application with Vitamin Education website which is designed for students.In this study, qualitative research method has been used. It is conducted with teachers who use Vitamin Teacher Portal to have valid results. The aim of this study is to work out the sufficiency level of this application from the point of view of teachers. By this means, it could be work out whether it is sufficient enough to meet the needs of teachers or not. We also to find out how effectively teachers, what they acquired from the portal in class

Integer Representations of the Generalized Symmetric Groups

In this paper, we construct a mixed-base number system over the generalized symmetric group $G(m,1,n)$, which is a complex reflection group with a root system of type $B_n^{(m)}$. We also establish one-to-one correspondence between all positive integers in the set $\{1,\cdots,m^nn!\}$ and the elements of $G(m,1,n)$ by constructing the subexceedant function in relation to this group. In addition, we provide a new enumeration system for $G(m,1,n)$ by defining the inversion statistic on $G(m,1,n)$. Finally, we prove that the \textit{flag-major index} is equi-distributed with this inversion statistic on $G(m,1,n)$. Therefore, the flag-major index is Mahonian on $G(m,1,n)$ with respect to the length function $L$
