Global and local media dynamics in identity construction among British Muslims after September 11

The terrorist attacks of September 11 have become a defining moment not only in the history of the US where they took place, but also in the history of Muslims around the world, particularly those living in Western countries. Muslim diasporas in the West have found themselves at the heart of global events and networks: a global war on terrorism, global flows of images and ideas, and a global Muslim community or Umma. Central to these various processes is undoubtedly the role played by new media and communication technologies, mainly transnational TV channels. Thus, based on an ethnographic study conducted in the city of Leeds, this paper explores the dialectic between local and transnational media, particularly British media and Arab satellite television channels, and the extent to which they have shaped identity building among British Muslims after September11. It argues that the use, appropriation and consumption of these media do certainly have a significant impact on how British Muslims define themselves. However, it demonstrates also that this role is far from being deterministic and it is only one among many other factors that condition identity building among British Muslims

The impact of ownership structure on bank risk: case of Tunisia

The ownership structure and risk are two important variables in the banking sector . Indeed , shareholders have incentives to monitor bank risk according to their objectives . In the context of this article , we used a sample of 19 banks in Tunisia over the period( 2000-2010) . Through the method of panel static , we found that public ownership has a negative effect on bank   risk , while private ownership and foreign ownership have a positive effect on bank risk. Key words: Ownership structure , public ownership , foreign ownership , private ownership , bank risk , panel stati

Potential fatigue strength improvement of AA 5083-H111 notched parts by wire brush hammering: Experimental analysis and numerical simulation

The effects of milling as machining process and a post-machining treatment by wire-brush hammering, on the near surface layer characteristics of AA 5083-H111 were investigated. Surface texture, work-hardening and residual stress profiles were determined by roughness measurement, scanning electron microscope (SEM) examinations, microhardness and X-ray diffraction (XRD) measurements. The effects of surface preparation on the fatigue strength were assessed by bending fatigue tests performed on notched samples for two loading stress ratios R0.1 and R0.5. It is found that the bending fatigue limit at R0.1 and 107 cycles is 20% increased, with respect to the machined surface, by wire-brush hammering. This improvement was discussed on the basis of the role of surface topography, stabilized residual stress and work-hardening on the fatigue-crack network nucleation and growth. The effects biaxial residual stress field and surface work-hardening were taken into account in the finite element model. A multi-axial fatigue criterion was proposed to predict the fatigue strength of aluminum alloy notched parts for both machined and treated states

Modeling of the Electrochemical Reactions at the Electrode-Electrolyte Interface of Nickel/Metal Hydride Batteries by an Equivalent Electrical Circuit

Based on the experimental impedance spectra, the electrochemical reactions that are deposed at the electrode-electrolyte interface can be modeled by equivalent electrical circuits. Each element used in the circuit must have a physical correspondence in the electrochemical system. In this work, a model has been proposed to a NiMH battery electrode to describe, in detail, the electrochemical process at the interface of this electrode. The theoretical impedance of a proposed circuit is a function of several variables. These adjusted variables to reach a good agreement between the theoretical spectra and the experimental spectra in the studied frequency. The Z-simplex software allows refining the experimental results. These results show a good superposition between the experimental spectra and the theoretical spectra corresponding to the proposed electric circuit. This leads to the conclusion that the proposed circuit describes the phenomena that take place at the interface of the hydride electrode

The impact of board administration on risk and financial stability of Islamic banks: an empirical investigation

The board of directors , risk and financial stability are important variables in the banking literature . Indeed , they are important for shareholders and other stakeholders of the bank .In this article , we have studied a sample of 40 banks ( 20 Islamic banks and 20 conventional banks ) in GCC countries over the period (2006…2012). We found that only the presence of institutional investors on the board of directors influence the financial stability of conventional banks . The Islamic banks are more stable when the debt ratio is low . The bank size has a positive but not significant impact on the financial stability of Islamic banks . This effect is negative on financial stability of conventional banks . Key words: board of directors , Islamic banks , conventional banks , risk , financial stabilit
