The protection of the freedom of speech, although of great value to a democratic society, does not include the pro tection of racist speech. The justification for regulating racist speech lies in the impact of racial ly-charged speech, not in the content of the speech itself. The regulation of racist speech should take into consideration thecriteriaofsubjectivemalignancy,necessityandproportionality.Due to their social status and special role in a democratic society, the media and political figures should bear a more stringent duty of care because of the harm and consequences of their racist remarks, which are far greater than those of other groups. During the pandemic, legal regula tion is required regarding remarks of politicians and the media that imply discrimination linked to CoVID-19.展开更多

The mating behavior of this species involves an overflying EAB male pouncing on an EAB female at rest on an ash leaflet before copulating. The male spots the female on the leaflet by visually detecting the iridescent green color of the female＇s elytra. As rearing EAB and then deploying dead females as decoys for trapping is both arduous and inconvenient, we decided to fabricate artificial decoys. We used a dead female to make a negative die of nickel and a positive die of epoxy. Decoys were then made by first depositing a quarter-wave-stack Bragg reflector on a polymer sheet and then stamping it with a pair of matched negative and positive dies to take the shape of the upper surface of an EAB female. As nearly 100 artificial decoys were fabricated from just one EAB female, this bioreplication process is industrially scalable. Preliminary results from a field trapping test are indicative of success.展开更多
