Used for this purpose today, the most effective strategy comes at the beginning of micro-credit system. Microcredit, in particular in the area of the individuals, and its opportunities to increase the credit to the users of the production process and ensure active participation in the society starting from the women＇s economic initiatives, but it cannot be considered as a micro-economic factors in the economy to facilitate an effective financial mechanism. Many studies in the literature have revealed that women＇s contribution to family income of households in poverty has created an important support. In addition, micro-credit system encourages women to create their own jobs, as the GNP （Gross National Product） of the countries contribution to increase employment opportunities. There are opinions arguing that, making use of the contact with communities in the potential female workforce satisfactory for women to create job opportunities to gain income is able to provide initial capital to the existing banking system, because in many countries＇ negative socio-cultural conditions, competing with men is much difficult. Micro-credit system, in the respect of changing countries socio-cultural and socio-economic structures is an important contribution. Microfinance occurred in recent years by rapid developments in Turkey since 2000, progress has been very professional. Our work in the field of micro-finance started operations in 2002, the Evaluation of Women＇s Work Association of Business Economics and the Grameen Bank realized Maya model adapted for Waste Prevention Foundation of Turkey should apply micro-finance. Micro-finance practices in the world and Turkey also compared practices. Turkey＇s application of micro-finance in banks＇ credit policies that support marketing activities related to marketing and sales strategies was examined by size. Also, emerging areas in Turkey, especially in the south-east region, the application of micro-finance loans contributed to the development of this geographical area were assessed. Studies of marketing and financial aspects of micro-finance were examined, the economic dimension of these practices by the country＇s social, cultural, political development has also been found to contribute significantly.展开更多

Starting from the short story ＂The Parrot and Descartes＂ by Pauline Melville, we argue that Cartesianism has influenced a view on education which tends to consider good and valuable what is ＂scientific＂, ＂objective＂ and ＂universal＂. The subjective and the local seem to be considered undesirable and unreliable. Brazilian scholars on the education field, such as Coracini and Souza are important support for our argument.展开更多
