The Quarks as Dirac States
As fermions, the quarks and leptons of the first family could be described as pairs of solutions of the Dirac equation (Dirac states). The color and electric charges are associated with the symmetry operations bringing the Dirac states into pairs. The obtained quark model is similar to that given by Han – Nambu, where the electric charges of the d and u quarks assume integer values. The quark s may have an inner structure formed from quarks of the first family, s = uud and s = uud.

Gender Politics and Research: Male and Female Violence in Intimate Relationships
This article reviews a wide range of research reports on male and female violence in intimate relationships and highlights the political nature of domestic violence research. The authors review incidence and prevalence-based research that uses quantitative surveys and illustrate how quantitative, family-focussed researchers tend to ignore the political and social context of domestic violence and the complex issues of gender and power. The authors argue that understanding the complexities of domestic violence requires clear definitions of what constitutes domestic violence and multi-method approaches to research, using a combination of quantitative and qualitative methodologies.
