Reflections on being an insider researcher: a study exploring the experiences of men accessing rural mental health services.

Background: An embedded single case-study design was used to explore the experiences of men in rural New Zealand accessing mental health services. It is essential for researchers to acknowledge positionality in case study research and the lead author used reflexive practice to acknowledge his values and beliefs.

Aim: To explore and demonstrate the reflexive process of the lead author's position as an inside researcher.

Comparison of PCR assays to detect Toxoplasma gondii oocysts in green-lipped mussels (Perna canaliculus).

Toxoplasma gondii is recognised as an important pathogen in the marine environment, with oocysts carried to coastal waters in overland runoff. Currently, there are no standardised methods to detect T. gondii directly in seawater to assess the extent of marine ecosystem contamination, but filter-feeding shellfish may serve as biosentinels.

Spin transport and bipolaron density in organic polymers.

We present a theory for spin-polarized transport through a generic organic polymer connected to ferromagnetic leads with arbitrary angle θ between their magnetization directions, taking into account the polaron and bipolaron states as effective charge and spin carriers. Within a diffusive description of polaron-bipolaron transport including polaron-bipolaron conversion, we find that the bipolaron density depends on the angle θ. This is remarkable, given the fact that bipolarons are spinless quasiparticles, and opens a new way to probe spin accumulation in organic polymers.
