Exploring the relation between gender politics and representative government in the Maghreb: analytical and empirical observations
No full textThis thesis uses analytical and empirical methods to explore the relation between gender standards and democratic standards in the Maghreb, which includes Algeria, Morocco, and Tunisia. The analytical approach consists of considering theories that link gender standards and democratic standards, and analyzing whether and to what extent such theories would apply or not apply to the Maghreb. The empirical approach consists of taking measurements that reflect gender standards and democratic standards across the three countries and four different milestones of their recent history (1970, 1980, 1990, 2000), and applying statistical methods to compute correlations and regressions. Because the empirical approach yields no significant correlation between gender standards and democratic standards in the Maghreb, I analyze this statistical correlation for other sets of countries that are part of Maghrebian identity: Arab countries, Muslim countries, African countries, and Mediterranean countries. The combined results of these analyses give us some insight into possible explanations of the empirical observations.Ph.D.Includes bibliographical references (p. 261-275)by Amel Mil
Hicri ilk iki asırda farklı şehirlerde amel telakkisi oluşumunda sünnet ve hadisin yeri
No full textHİCRİ İLK İKİ ASIRDA FARKLI ŞEHİRLERDE AMEL TELAKKİSİ OLUŞUMUNDA SÜNNET VE HADİSİN YERİ Bu tezde, hicri ilk iki asır boyunca farklı anlayışların temsil edildiği büyük ilim merkezlerindeki (emsâr) fukahânın amel telakkileri ele alınmaktadır. Tezin temel argümanı, amel anlayışının sadece Medine’ye has olmadığı, o dönemin diğer ilim merkezlerinde de kendilerine mahsus birer amel anlayışının oluştuğu ve bu anlayışların, hüküm istinbatı sürecinde fukaha tarafından dikkate alındığı iddiasıdır. Tezde öncelikle klasik ve modern literatürde amel meselesi ele alınmakta, ardından ikinci asırdaki şehirlerin amelleri (amelü’l-emsâr) işlenmekte, son olarak da ikinci asırdaki büyük ilim merkezlerini temsil eden fakihlerin (fukahâü’l-emsâr) amel anlayışları ve amel tartışmalarına yer verilmektedir. AMAL UNDERSTANDINGS OF THE FUQAHA AL-AMSAR AT THE SECOND CENTURY OF THE HIJRAH In this dissertation, ‘amal understandings of the famous and representative scholars (fuqahā al-amsār) at the second century of the Hijrah are scrutinized. The author mainly focuses on the fact that all of the big centers of the second century after the hijrah (al-Amsār) has its own understanding of ‘amal and, contrary to what is generally accepted, such an understanding is not unique to Madina. The author reviews the literature on the amal firstly, elaborates on the understandings of big centers at that time secondly, then focuses on the debates about the issue among some famous fuqahā in each center, namely Mālik b. Anas from Madina, Muhammad b. al-Hasan al-Shaybānī from Kufa, and al-Awzāī from Syri

No full textIn this paper a T-branch optical diplexer in two dimensional (2D) photonic crystal (PhC) to select two telecommunication wavelengths 1493.6nm and1553nm is investigated. In our design directional couplers (DC) and resonant cavity (RC) are utilized. A square lattice of silicon (Si) rods in air is used as fundamental structure. The coupling regions consist of three entire rows of decreased Si rods. Plane wave expansion method (PWE) and finite difference time domain (FDTD) method are utilized to analyze and simulate the characteristics of the designed device. The average transmission efficiency of our proposed diplexer is about 99.75%. High quality factor and extremely small crosstalk were achieved. The total size of the suggested design is 272.214 μm2, which is very suitable for nanotechnology based demultiplexing applications

Photonic band gaps in one-and two-dimensional photonic crystals based on a nanocomposite of ZnS and glass
No full textInternational audienceWe present the evolution of the refractive index of glass containing ZnS particles with various volume fractions. The optical properties of the new material, thus obtained, can be described by Maxwell–Garnett theory in terms of its effective dielectric permittivity. We investigate different aspects of photonic band gaps (PBGs) in one-dimensional (1D) and two-dimensional (2D) photonic crystals using the finite difference time-domain (FDTD) method. Changes in different structure parameters, such as the filling fraction and the shape, can affect photonic band gap properties such as location, number and width. We have also calculated the cavity mode of the microcavity in the hexagonal structure. We found that the intensity of the resonant defect mode is localized around 0.6 µm
