The increasing demands for accountability in higher education are resulting in calls for important personnel decisions--such as promotion, tenure, pay, and continuation--to be based directly on the outcomes of systematic faculty evaluations. This article provides a step-by-step procedure for developing a fair and meaningful faculty evaluation system on which such personnel decisions can be based. The procedure systematically involves faculty and administrators in the design and development of a faculty evaluation program that reflects the unique values, priorities, and heritage of an institution. The resultant faculty evaluation system integrates data from students, peers, and administrators to provide meaningful evaluative information for both faculty use in self-improvement efforts and administrative use in making personnel decisions that are based on a valid and reliable faculty performance record.

The arbuscular mycorrhizal (AM) symbiosis is responsible for huge fluxes of photosynthetically fixed carbon from plants to the soil. Carbon is transferred from the plant to the fungus as hexose, but the main form of carbon stored by the mycobiont at all stages of its life cycle is triacylglycerol. Previous isotopic labeling experiments showed that the fungus exports this storage lipid from the intraradical mycelium (IRM) to the extraradical mycelium (ERM). Here, in vivo multiphoton microscopy was used to observe the movement of lipid bodies through the fungal colony and to determine their sizes, distribution, and velocities. The distribution of lipid bodies along fungal hyphae suggests that they are progressively consumed as they move toward growing tips. We report the isolation and measurements of expression of an AM fungal expressed sequence tag that encodes a putative acyl-coenzyme A dehydrogenase; its deduced amino acid sequence suggests that it may function in the anabolic flux of carbon from lipid to carbohydrate. Time-lapse image sequences show lipid bodies moving in both directions along hyphae and nuclear magnetic resonance analysis of labeling patterns after supplying 13 C-labeled glycerol to either extraradical hyphae or colonized roots shows that there is indeed significant bidirectional translocation between IRM and ERM. We conclude that large amounts of lipid are translocated within the AM fungal colony and that, whereas net movement is from the IRM to the ERM, there is also substantial recirculation throughout the fungus.

Purpose: The NICHD Fetal Cell Isolation Study (NIFTY) was a multicentered project to isolate fetal cells from maternal blood to detect fetal chromosomal abnormalities. The project included a psychosocial component, which is the basis of this article. We examined the attitudes of high-risk pregnant women toward the availability of a maternal blood test to identify fetal chromosomal abnormalities, how women would respond to hypothetical normal and abnormal maternal blood testing results, and the factors associated with a woman's preference to have an invasive procedure in response to a normal maternal blood test. Methods: High-risk pregnant women (N ϭ 854) planning to have prenatal diagnostic invasive testing (amniocentesis or chorionic villus sampling) completed a survey. Results: The women highly favored maternal blood testing. Almost all women would seek invasive testing after an abnormal blood test. Only half of the women would seek invasive testing after a normal blood test; these women were older, more willing to terminate their pregnancy, and valued the increased accuracy of invasive testing more highly than women who would not have invasive testing after a normal maternal blood test. Conclusions:

Decisions made in developing evaluation systems and the small details of operation can render even the most sophisticated measurement instruments useless. What are the important practical considerations that can help institutions avoid these problems?.
