Lindsey Springer appeals the district court’s 1 adverse judgment in his diversity action alleging defamation. After careful review, we find his arguments to be without merit. See Schaaf v. Residential Funding Corp., 517 F.3d 544, 549 (8th Cir.) (de novo standard of review for Rule 12(b)(6) dismissal), cert. denied, — U.S. -, 129 S.Ct. 222, 172 L.Ed.2d 142 (2008), Johnson v. Blaukat, 453 F.3d 1108, 1112 (8th Cir. 2006) (de novo standard of review for summary judgment decision); Pony Computer, Inc. v. Equus Computer Sys. of Mo., 162 F.3d 991, 996 (8th Cir. 1998) (determination that claim is ripe for summary judgment is reviewed for abuse of discretion); Perkins v. Spivey, 911 F.2d 22, 28 n. 6 (8th Cir. 1990) (noting that otherwise proper ruling is not erroneous *297 merely because it has incidental effect of precluding jury trial). Accordingly, we affirm. See 8th Cir. R. 47B.
