During the thirteenth century, competition among the Italian merchants in Alexandria increased and each community sought wider trading privileges. Access to Alexandria's markets was an important addition to Venetian economic power, complementing the contemporary Venetian presence in Aleppo, in Acre and other Frankish ports, and in Constantinople after the fourth crusade in 1204. Venice differed from Pisa and Genoa in the thirteenth century because it was the only Italian merchant city that had signed four trade agreements with the sultans of Egypt. The Venetian treaties with the sultans formed the base of developing the Venetian maritime trade with Alexandria. They obtained privileges that allowed them to exercise commercial supremacy in the eastern Mediterranean. Unlike the other Italian communities settled in the sultan's lands, the Venetian merchants' privileges remained fixed and continued through the fourteenth and fifteenth centuries. This article aims to study and analyse commercial and diplomatic relations between Venice and the sultans, the Venetian merchants' privileges and their political and juridical status in Egypt.  相似文献

Framing this essay as a preface to a return to the field in order to collect more data for her study of the older, white southern women of her hometown, this researcher uses Laurel Richardson's (1994) concept of ''writing as a method of inquiry'' in order to revisit some of the places in which she has already done field work. By employing Deleuze and Guattari's (1980 1987) image of the nomad deterritorializing space, she revisits some of those spaces- mental space, the space of the text, and the space of theory- in order to work out of the failure of her received understanding of fieldwork and to think differently about the spaces and places in which her research takes place.  相似文献

The theoretical part of this paper argues for an embedding of the question of stability and change of teachers’ conceptions of learning into the researchers epistemological standpoint. The empirical part illustrates this statement by showing how changes in a teacher's conception of learning could be understood from a constructivist perspective. According to this perspective, conceptions are related to other relational and environmental variables that form a meaningful configuration. Thus, although conceptions of learning appear as relatively stable cognitive structures, they are also related to environmental variables to be managed by the teachers’ educators. This research result determines the discussion of the basic questions addressed in the title of this paper: why do we want to change teachers beliefs and how could we, as teachers’ educators, support these changes.  相似文献

Stereotypes, prejudice, and discrimination against the elderly (ageism) may manifest themselves in children at an early age. However, the factors influencing this phenomenon are not well known. Using both explicit and open-ended questions, this study analyzed the influence of personal and familial parameters on the views of 1,151 seven- to sixteen-year-old Belgian children and adolescents on the elderly. Four factors were found to affect these views: gender (girls had slightly more positive views than boys), age (ageism was lowest in 10- to 12-year-old, reminiscent of other forms of stereotypes and cognitive developmental theories), grandparents’ health, and most importantly, quality of contact with grandparents (very good and good contacts correlated with more favorable feelings toward the elderly, especially in children with frequent contacts).  相似文献

The objective of this paper is to measure the efficiency of high schools in Tunisia. We use a statistical data envelopment analysis (DEA)-bootstrap approach with quasi-fixed inputs to estimate the precision of our measure. To do so, we developed a statistical model serving as the foundation of the data generation process (DGP). The DGP is constructed such that we can implement both smooth homogeneous and heterogeneous bootstrap methods. Bootstrap simulations were used to estimate and correct the bias, and to construct confidence intervals for the efficiency measures. The simulation results show that the efficiency measures are subject to sampling variations. The adjusted measure reveals that high schools with residence services would have to give up less than 12.1% of their resources on average to be efficient.  相似文献
