"Specially noteworthy on two different grounds--firstly, because in it the relations to each other of ortho-, pyro-, and metaphosphoric acids and the corresponding salts were first pointed out; and secondly, because it formed the starting point of the idea of the basicity of acids."--Editor's pref.

Key life history traits such as breeding time and clutch size are frequently both heritable and under directional selection, yet many studies fail to document micro-evolutionary responses. One general explanation is that selection estimates are biased by the omission of correlated traits that have causal effects on fitness, but few valid tests of this exist. Here we show, using a quantitative genetic framework and six decades of life-history data on two free-living populations of great tits Parus major, that selection estimates for egg-laying date and clutch size are relatively unbiased. Predicted responses to selection based on the Robertson-Price Identity were similar to those based on the multivariate breeder’s equation, indicating that unmeasured covarying traits were not missing from the analysis. Changing patterns of phenotypic selection on these traits (for laying date, linked to climate change) therefore reflect changing selection on breeding values, and genetic constraints appear not to limit their independent evolution. Quantitative genetic analysis of correlational data from pedigreed populations can be a valuable complement to experimental approaches to help identify whether apparent associations between traits and fitness are biased by missing traits, and to parse the roles of direct versus indirect selection across a range of environments.

Intensive family preservation services (IFPS) is a program model that has been disseminated widely throughout the country, and has received federal recognition and monetary support since the early 1980s. Recently, IFPS has been criticized for seemingly being unable to prevent out-of-home placements. The authors contend that many evaluators and policy analysts have lost sight of the historical roots of IFPS, and are focusing only on recent fiscal and policy contexts when assessing IFPS program effectiveness. This article reviews the therapeutic and programmatic origins of IFPS including desired treatment outcomes, and suggests that evaluators and policy analysts redirect their focus accordingly.
