It has long been assumed that forests represented vast expanses of homogeneous green tissue, but this assumption is oversimplified. When walking through a forest, we usually focus our observations on a narrow band of green foliage, from ground level to about 2 m in height. This represents at most 10% of the foliage in mature forests, with the rest often high above our heads and consequently bey...

Prosthetic joint infection (PJI) is a serious complication of total knee arthroplasty (TKA). Control of infection after a failed two-stage TKA is not always possible, and the resolution of infection may require an above-knee amputation (AKA) or a the-knee (KF). The purpose of this review is to determine which treatment method (AKA or KF) yields better function and ambulatory status for patients...

An overview of VOC reactivity with respect to ground level ozone formation, and the mechanistic and environmental factors affecting it, are discussed. Methods of quantifying reactivity are described, and the roles of chemical mechanisms and environmental chamber data in reactivity quantification are discussed. A brief summary of ongoing reactivity-related research is presented, which can be cla...

The present study sought to examine for how hope and sexual assault are involved in suicidal risk in a sample of 325 college students. Specifically, we were interested to examine whether sexual assault may play an additive as well as interactive role in the prediction of suicidal risk (viz., suicidal behaviors & reasons for living) above and beyond hope. Results from regression analyses indicat...

The Implicit Association Test (IAT; Greenwald, McGhee, and Schwartz, 1998) has become a widely used method of measuring individuals’ implicit preferences based on the speed of sorting words or images into respective categories in a computerized task. Age IATs have been used to ascertain implicit preference judgments towards young and old faces and to compare these ratings with explicit, self-re...
