Control Over Dispute-System Design and Mandatory Commercial Arbitration

This article argues that mandatory arbitration is not itself the problem. The problem is instead that in some instances, one party to the dispute has exclusive control of the design of the dispute-resolution system. Consequently, research on mandatory arbitration should concentrate on who is structuring it, how they structure it, why this is so and how these choices affect dispute outcomes

Men’s Perinatal Mental Health in the Transition to Fatherhood

While fathers have come to be more involved with their partners and infants throughout the perinatal period, recent research has shown that roughly 10% of new dads experience mental health difficulties including depression and anxiety. Unfortunately, few psychologists receive focused training regarding conceptualizing, assessing, or treating common men’s issues in the period spanning from conception through a year post-partum. Because men tend not to seek mental health services during this period, the lack of scholarly attention to this vulnerable group reflects a commonly overlooked public mental health disparity. This article provides an overview of the key factors which research and theory suggest inform new fatherhood, along with an in-depth look at paternal postpartum depression. Implications for further practice and research are discussed. Specifically, the authors review psychosocial factors including masculine socialization, self-efficacy, social support, involvement with babies, and paternal postpartum mood and anxiety disorders. Finally, implications for research and practice are discussed

Correspondence between HBT radii and the emission zone in non-central heavy ion collisions

In non-central collisions between ultra-relativistic heavy ions, the freeze-out distribution is anisotropic, and its major longitudinal axis may be tilted away from the beam direction. The shape and orientation of this distribution are particularly interesting, as they provide a snapshot of the evolving source and reflect the space-time aspect of anisotropic flow. Experimentally, this information is extracted by measuring pion HBT radii as a function of angle with respect to the reaction plane. Existing formulae relating the oscillations of the radii and the freezeout anisotropy are in principle only valid for Gaussian sources with no collective flow. With a realistic transport model of the collision, which generates flow and non-Gaussian sources, we find that these formulae approximately reflect the anisotropy of the freezeout distribution.Comment: 9 pages, 8 figure
