Investigation of growth responses in saprophytic fungi to charred biomass
We present the results of a study testing the response of two saprophytic white-rot fungi species, Pleurotus pulmonarius and Coriolus versicolor, to charred biomass (charcoal) as a growth substrate. We used a combination of optical microscopy, scanning electron microscopy, elemental abundance measurements, and isotope ratio mass spectrometry (<sup>13</sup>C and <sup>15</sup>N) to investigate fungal colonisation of control and incubated samples of Scots Pine (Pinus sylvestris) wood, and charcoal from the same species produced at 300 °C and 400 °C. Both species of fungi colonise the surface and interior of wood and charcoals over time periods of less than 70 days; however, distinctly different growth forms are evident between the exterior and interior of the charcoal substrate, with hyphal penetration concentrated along lines of structural weakness. Although the fungi were able to degrade and metabolise the pine wood, charcoal does not form a readily available source of fungal nutrients at least for these species under the conditions used in this study

Where has the public gone and will communications technology bring them back?
This paper addresses the decreasing number of persons interested and participating in the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) or {open_quotes}Superfund{close_quotes} process. It also looks at communications technology to bring people back into participation in the Superfund process. The material studied and the technologies evaluated involve the Environmental Restoration Program at the Idaho National Engineering and Environmental Laboratory. The conclusions are probably valid for most DOE Superfund activities. Where has the public gone? The public has taken an interest in issues that they perceive have greater impact on their quality of life and that have an adverse impact on the environment, such as the shipment and storage of spent nuclear fuel. Will communications technology bring them back? Technology can do many things: it can reduce cost; it can allow quicker access to and from the public; it can offer more information; and it can increase interest because of its novelty for short periods of time, but it will not, in and of its own, create public involvement

Management of nonregulatory driven program risks
Evaluation of program risk is a significant part of any environmental restoration (ER) activity. While significant efforts have been made to assess risk to human health and the environment, program risks outside of CERCLA are handled on a fire drill basis. This paper explains a process that looks at program risk, directs mitigation efforts in the most useful path, and focuses corrective actions to obtain the most benefits from the resources used
The Relationship of Individual Capabilities and Environmental Support with Different Facets of Designers’ Innovative Behavior
Theoretical perspectives on employee creativity have tended to focus on an individual's capability to generate original and potentially useful ideas, whereas definitions of innovation also include the process of putting those new ideas into practice. This field study therefore set out to test how theoretically distinct types of individual knowledge and skills are related to different aspects of employees' innovative behavior in terms of both their new idea generation and idea implementation. Using a sample of design engineers (n = 169) in a multinational engineering company, measures were taken of different aspects of innovative work behavior (patent submission, real-time idea submission, idea implementation) and a range of individual capabilities (creativity-relevant skills, job expertise, operational skills, contextual knowledge, and motivation) and environmental features (job control, departmental support for innovation). Analyses showed that creativity-relevant skills were positively related to indices of idea generation but not to idea implementation. Instead, employees' job expertise, operational skills, and motivation to innovate demonstrated a stronger role in idea implementation. In terms of environmental factors, job control showed no positive relationship with innovative work behavior while departmental support for innovation was related to employees' idea generation but not idea implementation. The theoretical perspective that correlates of idea generation differ in certain aspects to those for idea implementation are confirmed by the study. Practical implications for organizations wishing to improve their innovativeness are discussed in terms of tailored training, development, motivational, and environmental interventions designed to improve the capabilities of individuals to engage in all parts of the innovation process
