what is the purpose of a recessed filter
Parliament (cigarette) Parliaments are one of few brands of cigarettes on the mainstream market to feature a recessed paper filter. Cigarette filters became common in most cigarettes in the 1950s. In the 1940s and 1950s, the brand was marketed for its unique filters, with advertisements reading, "Only the flavor touches your lips", and "Tobacco tastes best when the filter's recessed".[3] The brand also claimed that the recessed filter prevented tar from making contact with the smoker's mouth, unlike standard filters.[4][5][6] However, this recessed would also explain the popularity of the cigarette in another way: the sleeve would be suitable for snorting cocaine.[7]
Glass ceiling The glass ceiling metaphor has often been used to describe invisible barriers ("glass") through which women can see elite positions but cannot reach them ("ceiling").[11] These barriers prevent large numbers of women and ethnic minorities from obtaining and securing the most powerful, prestigious and highest-grossing jobs in the workforce.[12] Moreover, this effect prevents women from filling high-ranking positions and puts them at a disadvantage as potential candidates for advancement.[13][14]
