'Just talking about it opens your heart': meaning-making among Black African migrants and refugees living with HIV.

Meaning-making has emerged as a core construct in addressing trauma, loss or crisis. This paper considers how diasporic Black Africans living with HIV, who come from interdependent collectivist cultures where the norm is one of implicit support, extend their meaning-making strategies when faced with a diagnosis of HIV. In this qualitative study, 13 Black African migrants and refugees living with HIV in New Zealand were interviewed and the transcripts analysed.

Early assembly of the most massive galaxies.

The current consensus is that galaxies begin as small density fluctuations in the early Universe and grow by in situ star formation and hierarchical merging. Stars begin to form relatively quickly in sub-galactic-sized building blocks called haloes which are subsequently assembled into galaxies. However, exactly when this assembly takes place is a matter of some debate.

Evidence-based nursing: clarifying the concepts for nurses in practice.

Aim: To provide a critical analysis of key concepts associated with evidence-based nursing (EBN) to substantiate an operational definition for nurses to use in practice.

Background: Despite the plethora of literature surrounding what evidence-based nursing is and is not and how it differs from its cousins, evidence-based medicine and evidence-based practice, nurses still struggle to get evidence into practice. Several reasons for this have been reported, for example, a lack of understanding about what evidence-based nursing means or time to engage with and apply the evidence into practice.
