This article explores the concept of sects as social formations and the process of secularization sects has been undergone in the modern era, implying their exposition to political manipulation by various internal and external actors. We analyse this subject in the context of the modern Syrian State and, in particular, with reference to the political system established by President Hafez al-Asad in the 70’s. The use of sectarian ties appears as part of the regime patrimonial features, being a political strategy used in order to bind particular society’s groups to the regime. In this sense, sectarianism has nothing to do with religion and it requires to be analysed as a socio-political phenomenon. This kind of analysis permits also to confute the identification between the Asad regime and the Alawite community and to understand the complexity of the relation between the President and the community he originated from. 展开更多

This paper is focused on formability of multi-agent systems (MASs). The problem is concerned with the existence of a protocol that has the ability to drive the MAS involved to the desired formation, and thus, is of essential importance in designing formation protocols. Formability of an MAS depends on several key factors: agents' dynamic structures, connectivity topology, properties of the desired formation and the admissible control set. Agents of the MASs considered here are described by a general continuous linear time-invariant (LTI) model. By using the matrix analysis and algebraic graph theory, some necessary and sufficient conditions on formability of LTI-MASs are obtained. These conditions characterize in some sense the relationship of formability, connectivity topology, formation properties and agent dynamics with respect to some typical and widely used admissible protocol sets. 展开更多

The research is designed to examine current teaching practices and perceptions of elementary and secondary school language teachers so as to inform the design of a large-scale project on AWE (Automated Writing Evaluation) application in the Chinese classroom. The data indicated that teachers were confident in their computer use and understood formative assessment notions and their role in technology-enhanced teaching and learning. However, concerns were raised on the writing rubrics interpretation, the pedagogy on integrating AWE into teaching, and the suitability of the whole English software to Chinese learners. Solutions and suggestions were discussed. Sample lesson plans, pedagogy training and technical support were considered necessary for the participating teachers. 展开更多
