The Qur'an embraces cultural pluralism, emphasising that “People, We created you all from a single man and a single woman, and made you into races and tribes so that you should recognize one another. ”(Q. 49: 13). Moreover, peace is the most fundamental value in the Qur'an and Islam. The majority of the classical Muslim jurists, especially Hanafi school, emphasised that the reason for Muslims' fight against non-Muslims is Muslims' defense themselves against attacks, not non-Muslims' faith. Bediuzzaman Said Nursi (d. 1960) states that the only kind of jihad that is appropriate for the present age is spiritual or moraljihad. Furthermore, regarding Qur'anic approach to relations between Muslims and the People of the Book, Muslim scholars, in general, advocate sincere relations and trust between Muslims and the People of the Book. In addition, Said Nursi is one of the great Muslim scholars in interfaith dialogue in the 20th century. Finally, there is the need for establishing culture of coexistence, which practised before within a religious tradition such as Islamic tradition for many centuries in the history. Through achieving a culture of coexistence and peace, most conflicts can be resolved. 展开更多

This paper aims to parallelize the theorizations of Pierre Macherey and Gilles Deleuze.First,the author,according to Macherey,must have left something unsaid in his text.The unsaid or the narrative rupture is responsible for the multiplicity of the voices in the text,enabling the text to exist.Above all,Macherey argues that the unsaid or the narrative rupture emerges from how the author chooses to represent ideology.That is,Macherey’s so-called unsaid or narrative rupture is actually what the author could have said;it is in fact a potentiality embedded in the text.On the other hand,when postulating his virtual(ity)/actual(ity)couplet,Deleuze asserts that the virtual(ity)is actually a potentiality that can be tapped.To be more precise,the virtual(ity)has its own reality,and once actualized,it will be transformed into something entirely new and different.Here,the dialogical space between Macherey and Deleuze is plain to see:Macherey’s so-called unsaid or narrative rupture is literally Deleuze’s so-called virtuality.When the unsaid is said,a virtuality is actualized.And a potentiality is thus tapped.By such a reading strategy,we readers are presented with an enactment of an alternative case scenario of the text,namely,how the text could have been made over.In the end,an example of this reading strategy is provided:Macherey argues that Marquis de Sade’s desire-ruled society is more oppressive.What de Sade has left unsaid is the problematic relationship between desire and oppression.And it is exactly the potentiality in his works. 展开更多

In Orientalism,the author Edward W.Said stated that the Orient is negatively defined and serves to support the West'ssuperiority and strength.Citing a number of discourses and texts in the book,he broke the boundary between knowledge and poli-tics,and further examined how the knowledge that the Western colonial powers shaped about the Orient assisted to make a de-praved picture of the colonies,to justify their colonial ambition and suppression.Nevertheless,although Said attempted to explainthe selection of the oriental area in his discussion,a vast area of the Far East,such as China and Japan is excluded.Furthermore,he regarded the Orient as a completely passive colony,and negated any resistance from the Orient. 展开更多

In the last decades, there has been substantial development in modeling techniques of travel demand estimation. For low population areas the external trip estimation is important but usually neglected in travel demand modeling process. In Egypt, the researches in this field are scarce due to lack of data. Accordingly, this paper aims to identify and estimate the main variables that affect the travel demand in low population areas, and to develop models to predict them. The study focused on the Port Said Govemorate in North East Egypt. A special questionnaire had been prepared in 2010 depending on interviews of passengers at basic taxi terminals in Port Said. And 2211 filled questionnaires were offering for research. To analyze the data, two modeling procedures were used. One is the multiple linear regression and the other is the generalized linear modeling (GLM) applying normal distributions. It is found that GLM procedure offers more suitable and accurate approach than the linear regression for developing number of trips. The final demand models have statistics within the acceptable regions and, also, they are conceptually reasonable. These results are so important for Egyptian highway authorities to improve the efficiency of highway transportation system in Egypt. 展开更多
