However, the realities of the workplace are that information about performance and how individuals can add value to an organization is complex; that is, determining which activities to focus on is a fairly complex task because such information is nonlinear, whereby the importance of a certain activity may change depending on the level of performance at any given time. This article empirically examines whether providing complex, nonlinear feedback that reflects the complexities of the real world will result in a change in work outputs that reflect these nonlinearities. This article assesses whether employees can and do use complex feedback that reflects the complexity of the real world in the intended ways. In addition, this article examines whether individuals use feedback that includes priority information beyond feedback that reports on simple relative importance. Data were analyzed from 9 work units for time periods averaging a little over a year. Results indicate that, as predicted, when individuals have access to both complex, nonlinear priority information and simple, linear relative importance information, individuals can and do use the complex data in the intended way.

These flies are extremely important for medical-sanitary purposes and are useful to forensic entomology being used as an indicative of decomposition time in human corpses. The morphology of the larval and pupal stages of some species has been already studied by different authors demonstrating that it is possible to identify them in premature stages. In this study, Chrysomya megacephala egg ultramorphology was analyzed to describe its structure, generating data for further comparison between different species and genera. The blowflies were collected in Rio Claro city, SP, Brazil. Flies were attracted by fish carcasses and maintained in net cages; small portions of minced meat were placed in plastic pots for egg laying. Eggs were collected, fixed in alcoholic Bouin, prepared according to SEM routine and observed under Philips scanning electron microscope. C. megacephala eggs are oval with one flat face and another convex, measuring approximately 0.52 (+/-0.03) mm of length and 0.12 (+/-0.02) mm of width. The micropyle is circular in shape, with two perforations enclosed by countless small projections and is located in one of the extremities in the interface between the flat and convex faces. On the convex surface hexagonal imprints were observed, this surface is impermeable to water and gases. The flat surface has numerous round projections with different sizes, creating a permeable surface with a thinner chorion from which the larvae hatches. The larvae presents itself all wrinkled and with numerous cuticular projections with a thorn shape facing the posterior region. The cuticle projections with a thorn shape from C. megacephala larvae are probably a vestige of the thorns found in larvae of parasite Diptera.
