Abstract:
European cities are increasingly being recognised for the role they play in devising and implementing their own migration, integration and diversity policies. Yet very little is known about the local dimension of immigrant policymaking in crisis contexts. This introductory piece offers a rationale for analysing city-level immigrant policies in times of crisis and the salience of using crisis as a metaphor for the state of things, and outlines key scholarly works, debates, concepts and theories. It provides a range of historical and contemporary examples and considerations, and introduces an empirical city case study that is published as part of this mini-symposium. It argues that a crisis lens leads to a systematic understanding of local-level immigrant policymaking in recent and contemporary Western Europe. The mini-symposium's focus and findings should be relevant to both on-going academic and policy debates.

Basic Continuous Time Signals
The unit step function, denoted u(t), is zero for negative time values and one for positive time values, exhibiting a discontinuity at t=0. This function often represents abrupt changes, such as the step voltage introduced when turning a car's...
