[Q]: The yield of these compounds can be increased through ball milling of some of their components, and one mode of operation of these compounds proceeds through a mechanism called enantiomorphic site control. A process for the operation of these compounds that proceeds through migratory insertions and obeys the "principle of least nuclear motions" was developed by Cossee and Arlman. Compounds such bis(cyclopentadienyl)titanium chloride and bis(indenyl)zirconium dichloride, known as metallocenes, have been developed as an alternative to the traditional compounds of this type. Those traditional initiators include vanadium trichloride and triethylaluminum, and the product of the application of these compounds to alkenes can result in syndiotactic, isotactic, or atactic products. For ten points, identify these stereoselective compounds used to initiate polymerization, named for a German and an Italian chemist.

[Q]: During this event, a group of fourteen off-duty policemen formed a group called the Vengeance Squad with the intent of cleaning up the streets, and a convoy of taxi cabs delivered two hundred members of the U.S Navy to the site of this event. Police did not arrest the perpetrators of violence during this event; instead they arrested the victims on charges of suspicion of assault and vagrancy. The murder of Jose Diaz, whose body was found in the Sleepy Lagoon reservoir, was a precursor to this event. Leading up to this event, the City Council issued an ordinance in regards to (*) clothing, of which Norris Nelson said that ""if we can arrest people for being under dressed, we can do so for being over dressed. "" The mayor of Los Angeles said that racial prejudice was not a factor in this event, and that juvenile delinquents of many races had caused the problem. During the event, servicemen entered movie theatres and other public areas, dragged out minorities, and proceeded to beat them in the street. FTP, name this event that occurred in 1943, during which minorities in specific clothing were beaten badly.
