Background: Most qualitative studies exploring the impactof prostate cancer on men and their partners consider the dominant ethnicgroups in the USA, UK, Scandinavia and Australia, with generally concordantfindings. Other ethnic groups are likelyto have different experiences.
Aims: To explorethe impact of prostate cancer and its treatment on men and their partners fromthe less studied ethnic groups.
Methods: Using meta-ethnographyand textual narrative we synthesised peer reviewed qualitative interview-based studiesdated 2000-2015 focused on less well reported ethnic groups, as a sub-synthesisof a comprehensive metasynthesis on the impact of prostate cancer.
Results: Twenty-twopapers (15 studies) covering 11 ethnic groups were analysed. Nine studies considered black and minorityethnic groups in the UK and USA, with the remainder in Brazil, the PacificIslands, Israel, Turkey and Japan. We collected first and second order themesfrom the studies to develop conceptual third order themes with the following specificto the US and UK minority groups andPacific Islanders: A spiritual continuum: from the will of God to God ashelpmate; One more obstacle in the lifelong fight against adversity; Developingsensitive talk with a purpose (on disclosingthe cancer to informal networks in culturally appropriate ways). Themes from theother studies were similar to those in the overall metasynthesis.
Conclusions: Healthcare for prostate cancer should takeaccount of contextually and culturally specific coping mechanisms andpsychosocial factors in minority ethnic groups. More studies are needed indiverse ethnic groups.

This paper presents an extension to the energy vector, well known in the Ambisonics literature, to improve its predictions of localisation at off-centre listening positions. In determining the source direction, a perceptual weight is assigned to each loudspeaker gain, taking into account the relative arrival times, levels, and directions of the loudspeaker signals. The proposed model is evaluated alongside the original energy vector and two binaural models through comparison with the results of recent perceptual studies. The extended version was found to provide results that were at least 50% more accurate than the second best predictor for two experiments involving off-centre listeners with first- and third-order Ambisonics systems.
