title: Ethical review and reflexivity in research of children's sexuality

authors: Flanagan, Paul G.

subjects: child sexuality

abstract: Research in the area of children's sexuality is largely based on observational and retrospective studies. Childhood studies literature increasingly calls upon the inclusion of children's voices, yet with sensitive topics ethical positions often close research possibilities in the territories of children's worlds. Children are perceived as a vulnerable group, especially when the investigation focuses on their sexual development and activity – and it is perceived that this research area is too sensitive and potentially harmful to children. Within the context of beginning a qualitative study on children's sexuality in New Zealand (including interviews with children), this paper reviews a number of studies of childhood research. These studies provide a glimpse at how research focusing on children has been conducted, and explores ethical issues arising in such research. The significance of researcher reflexivity is acknowledged for ethical research practice. The paper concludes that in research on children's sexuality a process of ethical review is limited, and that researcher competence in sensitive investigations is required. Among other difficulties for this researcher (with a professional background in child and family therapy) is the vulnerability of being a man choosing to research children.

title: New exact Betchov-like relation for the helicity flux in homogeneous turbulence

authors: Capocci, Damiano

abstract: In homogeneous and isotropic turbulence, the relative contributions of different physical mechanisms to the energy cascade can be quantified by an exact decomposition of the energy flux (Johnson, Phys. Rev. Lett., vol. 124, 2020, 104501; J. Fluid Mech., vol. 922, 2021, A3). We extend the formalism to the transfer of kinetic helicity across scales, important in the presence of large-scale mirror-breaking mechanisms, to identify physical processes resulting in helicity transfer and quantify their contributions to the mean flux in the inertial range. All subfluxes transfer helicity from large to small scales. Approximately 50% of the mean flux is due to the scale-local vortex flattening and vortex twisting. We derive a new exact relation between these effects, similar to the Betchov relation for the energy flux, revealing that the mean contribution of the former is three times larger than that of the latter. Multi-scale effects account for the remaining 50% of the mean flux, with approximate equipartition between multi-scale vortex flattening, twisting and entangling.

title: Audiences, referees, and landscapes: Understanding the use of Māori and English in New Zealand dual language picturebooks through a sociolinguistic lens

authors: Daly, Nicola

abstract: When non-dominant perspectives are represented in children's literature, it is labelled multicultural, and this form of literature has much potential for altering existing power structures in society. Bishop (1990) first introduced the metaphor of multicultural children's literature offering the possibility of windows - an opportunity to see into others' worlds; mirrors - an opportunity to see your own world being reflected back; and glass sliding doors - an opportunity to step into a world through a book. However, to date, any exploration of the extent to which language diversity contributes to the representation of non-dominant perspectives in multicultural children's literature has been limited, and the use of sociolinguistic theories to frame and theorise such explorations almost non-existent.
