In Iran, due to lack of comprehensive understanding about the participation notion and its necessary socio-economic and political infrastructures, participatory decision-making has faced with some serious challenges in both processes of preparing and implementing. The present paper focuses on providing practical strategies for preparing collaborative urban plans in Iran's conditions. Also it seeks to answer this question: What is the role of planners to prepare a real collaborative plan? It is assumed that a conceptual model for collaborative planning can be fitted with Iran's conditions by means of integrating the fundamental philosophic ideas of participatory planning such as theories of Paul Michel Foucault and Jürgen Habermas, given the fact that the present situation of collaborative planning in Iran needs a supportive theory which is compatible with power structures of Iranian urban planning system. In this regard, the Habermas' theory of “communicative action” and the Foucault's theory of “power structures” are reviewed by a comparative analysis methodology to present an integrated conceptual model for collaborative planning in Iran's condition. At the end, the CDS (City Development Strategy)---making process of Anzali City of Iran is analysed to examine this claim in the practice. The results yield that enabling urban planners to act as communication facilitators during planning can direct the collaborative planning in Iran from theory to a real practice by means of integrating the positive aspects of communication and power.展开更多

In this protocol, the communication parties exchange their secret information deterministicaJly in two rounds. The devices and efficiency of the protocol are discussed respectively. We also show the security of the protocol against intercept-resend and Trojan-Horse eavesdropping attacks.展开更多

A quasi-experimental design was used to answer the first question. The participants were pre-tested and streamed into two classes of equal reading comprehension abilities. The intervention consisted of four texts of equal length, comprising two rated in a pilot study as conceptually difficult/linguistically easy, and two rated as conceptually easy/linguistically difficult. The subjects in each class were involved in reading the two types of texts collaboratively and privately for four sessions. After reading the text, the subjects were asked to answer in writing 10 comprehension questions. Collaborative reading resulted in consistently and significantly higher scores than private reading for all four texts. Qualitative methods were employed to answer the last two questions. Group interactions during collaborative reading were tape recorded and transcribed, and 10 students selected at random from the two classes were interviewed in depth. Analysis of the group interaction transcripts revealed that the participants were using five major strategies in co-constructing meaning from the texts. These strategies included brainstorming, clarifying the language, summarizing, paraphrasing, and interaction management. Other minor (i.e., infrequent) strategies were also identified, such as making PCU/NCU (positive/negative claim to understand), eliciting confirmation, and confirming.展开更多

Since the late 15th century, the Ottoman Turks had been feared as menace, as the most dreadful enemies not only of the inhabitants of the Habsburg ruled countries but of the whole world of Christianity, and the Ottoman Turks did pose a permanent threat to their neighbours in Central Europe. The situation changed around 1700 when the Habsburgs succeeded in integrating the entire Hungarian Kingdom into their empire. From the early 18th century onwards the Ottoman Turks were no longer regarded as fierce fighters but increasingly as neighbours living in an unknown and totally different world and gained more and more curious attention. This change was not only the consequence of the new balance in power politics but mainly a sequel of gaining much more information. Up to the late 17th century the knowledge about the Ottoman Turks was based primarily on what had been reported by ambassadors travelling to Constantinople while in the 18th century people of several strands of life reported about their experiences. After the Peace of Passarowitz in 1718 trade agreements between the two states enabled activities of merchants and tradesmen who learned to know things about their eastern neighbours which were totally new to the Middle European contemporaries. Additionally, some elements of this "oriental" culture were taken over and were to become typical for Central Europe later on. The Turks were curiously observed as strange and fascinating neighbours. In the course of the movement of enlightenment from the middle of the 18th century onwards one aspect of this culture lost much of its dreadfulness: the fact that the Ottoman Turks were infidels. So it did not take very long until Ottomans were seen as being capable of true humanity regardless their religion. In the 19th century the multiethnic state organizations of the Ottoman Empire and the Habsburg Monarchy became outmoded in this age of nationalism. They realized their common interests and started a cooperation which eventually ended up as alliance in theWorld War I. From the point of view of power politics however, the Ottoman Empire was regarded as “sick man at the Bosporus”. In the following the changes of the image are shown as an overview by observing the criteria against the background of the most important historical events. The details of how this process worked are still pretty murky. Further investigations are already on the way and will bring more light into the reasons and the mechanism of this development.展开更多
