This experiment measures the effects of indoor plants on participants' productivity, attitude toward the workplace, and overall mood in the office environment. In an office randomly altered to include no plants, a moderate number of plants, and a high number of plants, paid participants (N = 81) performed timed productivity tasks and completed a survey questionnaire. Surprisingly, the results of the productivity task showed an inverse linear relationship to the number of plants in the office, but self-reported perceptions of performance increased relative to the number of plants in the office. Consistent with expectations, participants reported higher levels of mood, perceived office attractiveness, and (in some cases) perceived comfort when plants were present than when they were not present. Decreased productivity scores are linked to the influence of positive and negative affect on decision making and cognitive processing.

The Encomium Emmae Reginae was written in the early 1040s to support the interests of Queen Emma amidst the factionalism which marked the end of the period of Danish rule in England. This article argues that the Encomium was shaped by its production and reception in the distinctively multilingual environment of King Harthacnut's court. Attention to Emma's key role in negotiating the interaction of the English, Norse, French, Flemish and Latin literary and linguistic cultures which were present in the Anglo‐Danish court reveals growing lay claims to Latin literary culture in eleventh‐century England.
