Superfluorescent Rayleigh scattering from suspensions of dielectric particles

We demonstrate that superfluorescent scattering of light can occur when laser light is incident on a collection of dielectric Rayleigh particles suspended in a viscous medium. Using a linear stability analysis, an expression for the spatiotemporal evolution of the scattered (probe) field is derived. An approximate condition for the progression of the interaction into the nonlinear regime is deduced and it is shown that, in the nonlinear regime, the scattered field intensity shows the characteristic quadratic dependence on particle density expected from a superfluorescent or superradiant process, once the effects of pump depletion are accounted for

Fundamental Researcher Attributes: Reflections on Ways to Facilitate Participation in Community Psychology Doctoral Dissertation Research

As novice researchers, Community Psychology doctoral students encounter fresh challenges when they attempt to facilitate participation by members of the community in their dissertation projects. This article presents the merit in adopting fundamental researcher attributes, which have been described in published academic literature as personal characteristics that facilitate participation by members of the community in research studies. The value of these researcher attributes is exemplified in the discussion of one of the author’s experiences in the early stages of his dissertation research process. This article also presents new researcher attributes for facilitating participation by community members that the author recognised after critical reflection on his experiences during the same research process. Cultural humility, shared vulnerability, reflexivity, methodological flexibility, academic assiduity and creative resourcefulness are researcher attributes doctoral students should consider adopting and developing if they intend to facilitate participation by members of the community in their dissertation projects
