Newcomers to Canada whose names index identities other than “white” and “English” face pressure to alter their names to facilitate integration. Some immigrants oppose the forces of conformity and refuse to assimilate their names. In interviews, they explain this stance using discourses of agency centring on a belief in true names, a moral obligation to get names right, and a need for a strong self. Focusing on ideologies of identity and language in their meta-agentive discourses, I argue that the act of immigrants keeping their ethnic names is a political move to redistribute responsibility for the integration of newcomers into the host society.

AbstractAn analysis of the self-focusing of highly intense chirped pulse laser under exponential plasma density ramp with higher order value of axial electron temperature has been done. Beam width parameter is derived by using paraxial ray approximation and then solved numerically. It is seen that self-focusing of chirped pulse laser is intensely affected by the higher order values of axial electron temperature. Further, influence of exponential plasma density ramp is studied and it is concluded that self-focusing of laser enhances and occurs earlier. On the other hand defocusing of beam reduces to the great extent. It is noticed that the laser spot size reduces significantly under joint influence of the density ramp and the axial electron temperature. Present analysis may be useful for the analysis of quantum dots, the laser induced fusion and etc.
