Herein we report on a straightforward access method for boron dipyrromethene dyes (BODIPYs)-coumarin hybrids linked through their respective 8- and 6- positions, with wide functionalization of the coumarin fragment, using salicylaldehyde as a versatile building block. The computationally-assisted photophysical study unveils broadband absorption upon proper functionalization of the coumarin, as well as the key role of the conformational freedom of the coumarin appended at the meso position of the BODIPY. Such free motion almost suppresses the fluorescence signal, but enables us to apply these dyads as molecular rotors to monitor the surrounding microviscosity.

Evidence-based practice (EBP) is challenging for most nurses due to the time constraints of caring for patients and the emerging pressures of a changing health service. To explore these challenges, and thus to establish possible means of overcoming them, three focus groups ( n = 17) with children’s nurses were conducted. Participants were asked how they would define EBP, what the barriers to EBP were, what skills they needed to help access evidence and how they could integrate evidence into everyday practice. Data were analysed thematically and the anticipated themes of definitions of EBP, barriers, education and nursing culture were determined. Important subthemes were personal and employer disengagement, passivity and lack of resource utilisation. Passive use of evidence readily available in patient folders and on the wards was common. It seemed that little consideration was given to how often this evidence was updated. Nurses define their access to evidence as primarily passive in nature. This is reinforced by a lack of ready access to ongoing education and a perceived lack of investment at institutional level in their continued engagement with evidence. Promoting EBP needs to engage more with those ritual and traditional aspects of nursing culture to challenge these perceptions.

Horace's Epistle to Torquatus (Ep. 1.5)

Horace addresses Torquatus again in Carm. 4.7. There the poet distinguishes three cardinal qualities: Torquatus's genus, his facundia, and hispietas. Since Horace distinguishes them they were no doubt qualities on which Torquatus prided himself, but they are, in any case, the key by which Torquatus slips into Horace's lyric. I suggest that we can use the same key to open up the Epistle, and that by taking up these qualities we have ready access to the wit of the poem, carefully predicated upon its addressee.
