"Cultural transmission of behaviour is an important aspect of many animal communities ranging from humans to birds. Male humpback whales ... sing a repetitive, stereotyped, socially learnt and culturally transmitted song display that slowly evolves each year. Most males within a population sing the same, slow-evolving song type; but in the South Pacific, song ‘revolutions’ have led to rapid and complete replacement of one song type by another introduced from a neighbouring population. Songs spread eastwards, from eastern Australia to French Polynesia, but the easterly extent of this transmission was unknown. Here, we investigated whether song revolutions continue to spread from the central (French Polynesia) into the eastern (Ecuador) South Pacific region. Similarity analyses using three consecutive years of song data (2016–2018) revealed that song themes recorded in 2016–2018 French Polynesian song matched song themes sung in 2018 Ecuadorian song, suggesting continued easterly transmission of song to Ecuador, and vocal connectivity across the entire South Pacific Ocean basin." more »

"GAO’s interviews with claims processors suggest that they evaluate claims for these conditions inconsistently based on inaccurate interpretations of VA’s claims processing procedures. Specifically, during interviews at three selected offices that process Agent Orange claims, GAO heard inaccurate statements about (1)when the 1-year manifestation period requirement applies and (2) what types of evidence can be used to address this requirement or to support requesting a medical opinion that could be used to support veterans’ claims. VA’s guidance does not clearly address these issues. Without clear guidance, claims processors may incorrectly apply the 1-year manifestation period requirement when veterans have evidence suggesting a direct connection to service and, in turn, could inappropriately deny benefits to some Vietnam veterans." more »

" History shows that the employment costs of bringing down inflation are likely to increase with delay, as high inflation becomes more entrenched in wage and price setting. The successful Volcker disinflation in the early 1980s followed multiple failed attempts to lower inflation over the previous 15 years. A lengthy period of very restrictive monetary policy was ultimately needed to stem the high inflation and start the process of getting inflation down to the low and stable levels that were the norm until the spring of last year. Our aim is to avoid that outcome by acting with resolve now." more »

The 2022 Urban Trauma Library Study, spearheaded by a group of New York City-based librarians, surveyed urban library workers and found nearly 70% said they had dealt with patrons whose behavior was violent or aggressive, from intimidating rants and sexual harassment to people pulling guns and knives or hurling staplers at them. Few of the workers felt supported by their bosses. “As the social safety net has been dismantled and underfunded, libraries have been left to pick up the slack,” wrote the authors, adding that most institutions lack practical guidelines for treating traumatic incidents that over time can lead to “compassion fatigue.” Library administrators have begun to acknowledge the problem by providing training and hiring staff members experienced in social services. more »
