When a single job is the target, established job analysis approaches provide relatively straightforward methods for identifying performance requirements. However, when multiple jobs are involved, the identification of a single set of relevant performance dimensions can be more daunting. In the application here, there was also a compelling requirement to develop a dimension set that conformed with U.S. Navy fleet personnel perceptions of the performance domain. Accordingly, the behavioral performance constructs that experienced Navy officers believed differentiate effective from ineffective supervisory performance were gathered using a personal construct theory protocol. We then used a methodology suggested by Borman and Brush (1993) to integrate and summarize these personal work constructs, to provide-through a series of qualitative and quantitative strategies-a dimension set targeted toward supervisors in all Navy communities. The resulting dimensions revealed certain themes that might not have emerged if traditional job analysis strategies had been used. The dimension set and the resulting behaviorally anchored rating scales appear widely relevant to Navy supervisor jobs, and the performance appraisal system that employs the scales is nearing implementation. In addition, performance feedback and development tools were developed to complement the performance appraisal system.

Agricultural production systems that also provide opportunities to conserve biodiversity will be a crucial component of integrated and sustainable land use in mixed farming landscapes and should be considered and evaluated. Alley farming is an innovative farming system that aims to increase farm profitability while also enhancing environmental outcomes. Alley farming incorporates belts of woody perennial plants such as trees or shrubs, interspersed with alleys of conventionally rotated cropping and livestock grazing land. In the present study, we assessed the impacts on terrestrial biodiversity of alley farming with the native perennial chenopod shrub old man saltbush (Atriplex nummularia Lindl.) in central western New South Wales. Terrestrial biodiversity conservation status was assessed by site surveys conducted in spring 2005, 2006 and 2007 at 15 old man salt bush alley farming sites (OMSB), 15 conventionally managed sites and three native woodland remnants in and around the Condobolin Agricultural Research and Advisory Station in the central western plains of New South Wales. Biodiversity surveys included an assessment of ‘site condition’ – a metric of biodiversity conservation status at the site scale based on measurement of 10 habitat and vegetation condition attributes, compared against benchmark values for the appropriate native ecosystems with relatively little recent anthropogenic modification. Bird surveys were also conducted to assess the diversity and abundance of birds in OMSB, conventional and remnant woodland sites in four functional response groups. Site condition was significantly higher at remnant woodland sites than at conventional farming and OMSB alley farming sites. Remnant woodland sites had greater native overstorey cover and native ground cover of forbs, more trees with hollows, presence of at least some overstorey regeneration and the presence of fallen logs. Site condition was also significantly higher at OMSB sites than at conventional sites and increased significantly across 3 years. By the third year after establishment, OMSB sites had higher native plant species richness and native mid-storey cover than did conventionally farmed sites. These attributes increased markedly over time at the OMSB sites whereas they did not increase at conventional or remnant woodland sites. Native grasses and forbs established under and around the saltbush plants, indicating that OMSB alley plantings can provide habitat for a wide range of native plant species, enhancing biodiversity values of these areas through improved structure and composition. Improved habitat condition at the OMSB sites after 3 years did not lead to a significantly higher diversity or to a higher overall abundance of birds at the OMSB than at conventional sites. Furthermore, diversity and abundance of birds at both OMSB and conventional sites remained significantly below those of remnant woodland sites. Some decliner bird species were observed using OMSB sites, but not conventional sites. Old man saltbush alley farming can provide direct on-site benefits for native biodiversity by improving the structure, function and composition of vegetation at the site or paddock scale. If proposed as a replacement to conventional crop–pasture rotation, OMSB alley farming can enhance biodiversity conservation values, and where production benefits are likely, could play an important role in the integration of production and conservation as a synergistic ‘win–win’ system in mixed farming enterprises.

The U.S. Navy conducted usability testing for the Navy's Human Performance Feedback and Development (HPFD) and ePerformance system to capture both quantitative and objective data as well as qualitative and subjective data from participants to identify potential sources of error and user burden. A total of 57 officer and enlisted supervisors and nonsupervisors took part in usability testing conducted at 3 Navy test sites. Each participant completed a usability test scenario and took part in focus group interview debriefings of their usability testing session to elicit recommendations for improvement and cultural factors that might affect system implementation. Results identified various usability errors, their frequency, and duration, as well as recommendations for improvement. In addition, user ratings of the system and qualitative data from focus group interviews indicate that system users believe the systems worked well. Focus group interview results indicate that the frequency and severity of connectivity problems had a negative effect on user
