We calculate the two-loop β-functions for soft supersymmetry-breaking interactions in a general supersymmetric gauge theory, emphasising the role of the evanescent couplings and masses that are generic to a non-supersymmetric theory. We also show that a simple set of conditions sufficient for one-loop finiteness renders a theory two-loop finite, and we(More)
BACKGROUND Social support theory and observational risk factor studies suggest that increased antenatal psychosocial support could prevent post-natal depression. We used empirical knowledge of risk and protective factors for post-natal depression not employed previously in order to develop and evaluate an antenatal preventive intervention. METHODS We(More)
'Behavioral contagion' refers to an increased tendency for a behavior to be performed when socially related persons have already performed it. So understood, behavioral contagion may be involved in criminality, conduct disorder, drug abuse, suicide, and teenage pregnancy. In a recent paper we showed that contagion, when present, generates highly distinctive(More)
A behavioral disorder is "contagious" if the risk to a given individual increases when someone in that person's vicinity, family, or social group develops the disorder. So understood, behavioral contagion may be involved in criminality, conduct disorder, drug abuse, suicide, and teenage pregnancy. Previous papers have shown that contagion generates highly(More)
