Islamization of the populace after the invasion was certainly rapid, but it has been argued that this reflects an exponential social process of religious conversion rather than a substantial immigration; a sizeable proportion of the indigenous population (the so-called Mozarabs) was allowed to retain its Christian practices, as a result of the religious tolerance of the Muslim rulers.
Civil-liberties activists, human-rights groups and ethnic voters (who have increased to sizeable numbers with past immigrations) will not allow draconian measures against immigrants.Thus, we need a seismic shift of immigration policy away from attempts at curbing migration to coping with it.
This last result i.e., the sizeable and significant impact of the number of immigration-related stories on the propensity to support the Senate plan is interesting because it provides additional evidence that the media effects we are estimating are not driven only by self-selection.
Overall, the evidence we have gathered is consistent with the fact that self-selection explains a sizeable portion of the correlation between policy attitudes on illegal immigration and media exposure, but not the whole of it: persuasion, as best exemplified by the Lou Dobbs effect, appears to be a non-negligible factor.
Immigration was a significant factor in the referendum campaign, with a sizeable number of those who voted to leave the EU citing it as reason for supporting Brexit.
While the proportion of foreign-trained family physicians practicing in Canada has declined from 31.9% in 1978 to 24.9% in 2008 and for foreign-trained specialists from 29.7% to 21.5% in 2008, immigration and entry into practice of foreign-trained physicians continues in sizeable numbers [ 3].
Few states are as likely to spar more with the new Republican president than California, where the Affordable Care Act has led to a sizeable expansion of government-subsidized healthcare and where liberal reforms of the nation's immigration policy have strong support.
Immigration has brought Islam (4.9%) and Eastern Orthodoxy (around 2%) as sizeable minority religions.
Most interestingly, low-skilled immigration resulted in a weakening of the negative correlation between fertility and work and a sizeable increase in the joint likelihood of childbearing and labor force participation.
