Does abstaining from alcohol in high school moderate intervention effects for college students? Implications for tiered intervention strategies.

Brief motivational intervention (BMI) and personalized feedback intervention (PFI) are individual-focused brief alcohol intervention approaches that have been proven efficacious for reducing alcohol use among college students and young adults. Although the efficacy of these two intervention approaches has been well established, little is known about the factors that may modify their effects on alcohol outcomes. In particular, high school drinking may be a risk factor for continued and heightened use of alcohol in college, and thus may influence the outcomes of BMI and PFI.

Nickel(II) complexes of monofunctionalized pyridine-azamacrocycles: synthesis, structures, pendant arm "on-off" coordination equilibria, and peroxidase-like activity.

Novel nickel(II) complexes of pyridine-azamacrocycles (PyMACs) with pendant arms have been synthesized using simple, direct, and selective mono-N-functionalization of PyMACs. These complexes have been characterized by spectroscopy and X-ray crystallography. Nickel(II)-PyMAC complexes with a flexible pendant arm bearing a tertiary amine, a carboxylic acid, or an amide group exhibit structural and color changes due to "on-off" arm coordination to the metal center.
