QCD and strongly coupled gauge theories : challenges and perspectives

We highlight the progress, current status, and open challenges of QCD-driven physics, in theory and in experiment. We discuss how the strong interaction is intimately connected to a broad sweep of physical problems, in settings ranging from astrophysics and cosmology to strongly coupled, complex systems in particle and condensed-matter physics, as well as to searches for physics beyond the Standard Model. We also discuss how success in describing the strong interaction impacts other fields, and, in turn, how such subjects can impact studies of the strong interaction. In the course of the work we offer a perspective on the many research streams which flow into and out of QCD, as well as a vision for future developments.Peer reviewe

What are the parenting experiences of fathers? The use of household survey data to inform decisions about the delivery of evidence-based parenting interventions to fathers

Participants were 933 fathers participating in a large-scale household survey of parenting practices in Queensland Australia. Although the majority of fathers reported having few problems with their children, a significant minority reported behavioral and emotional problems and 5% reported that their child showed a potentially problematic level of oppositional and defiant behavior. Reports of child problems were associated with fathers' levels of personal stress and socioeconomic disadvantage. Approximately half of all fathers reported the use of one or more coercive parenting strategies (shouting and yelling, hitting the child with their hand or with an object) with fathers' use of hitting being associated with child behavior difficulties. Fathers reported low rates of help seeking or participation in parenting courses, with socially disadvantaged fathers being less likely to complete parenting programs than other fathers. Implications for research on increasing fathers' participation rates in parenting programs are discussed and directions for future research highlighted
