Global Parameter and Helioseismic Tests of Solar Variability Models

Abstract: We construct models of the structure and evolution of the Sun which include variable magnetic fields and turbulence. The magnetic effects are (1) magnetic pressure, (2) magnetic energy, and (3) magnetic modulation to turbulence. The effects of turbulence are (1) turbulent pressure, (2) turbulent kinetic energy, and (3) turbulent inhibition of the radiative energy loss of a convective eddy, and (4) turbulent generation of magnetic fields. Using these ingredients we construct five types of solar variability models (including the standard solar model) with magnetic effects. These models are in part based on three-dimensional numerical simulations of the superadiabatic layers near the surface of the Sun. The models are tested with several sets of observational data, namely, the changes of (1) the total solar irradiance, (2) the photospheric temperature, (3) radius, (4) the position of the convection zone base, and (5) low- and medium-degree solar oscillation frequencies. We find that turbulence plays a major role in solar variability, and only a model that includes a magnetically modulated turbulent mechanism can agree with all the current available observational data. We find that because of the somewhat poor quality of all observations (other than the helioseismological ones), we need all data sets in order to restrict the range of models.

Addressing domestic violence in Canada and the United States: The uneasy co-habitation of women and the state

Abstract: Feminist sociologists and activists have drawn attention to how violence against women is linked to structural and cultural factors that subordinate women, mainly intersecting inequalities and limited rights. Mobilization by the Battered Women’s and Anti-Violence Movements, media attention, legislation, and policy have increased awareness and support to address violence against women. However, activists and researchers have also critiqued the problems with invoking the power of the state. The authors interrogate the role of the state in addressing domestic violence, especially in the context of immigration in the neoliberal era. More specifically, they examine how domestic violence, as legal and policy discourse, has been framed in Canada and the US, and the resulting forms of intervention. Through a critical literature review the authors show how this framing impacts immigrant and racialized women facing domestic violence. The article highlights problems and gaps in the respective discourses, as well as ...
