    Notes: Abstract There is growing interest in research to develop potential agroforestry models for temperate climates. In Washington State, recent studies and anecdotal information suggest that agroforestry is already employed by land managers, and if so, this experience should inform future research efforts. Because this population is not well defined, a mail survey was designed to: 1) Assess Washington land manager awareness of agroforestry, 2) assess perceptions of agroforestry as a land management tool, 3) assess the perceived potential opportunities or obstacles for land managers to practice agroforestry, and 4) identify landowner groups believed to be practicing agroforestry in Washington State. Three groups of land managers were surveyed: employees of the Soil Conservation Service (SCS), Washington State University Cooperative Extension Service (WSUCE) and OTHER, consisting of university faculty, private land managers, State and Federal land managers and owners of small natural resource businesses. Agroforestry was not a new concept for most (94%) respondents, further 55% of those familiar with agroforestry were practicing agroforestry or providing advice to landowners who were practicing agroforestry. ‘Use in (government mandated) soil conservation plans’ on farmland (100% of all respondents) was the most frequently cited potential application for agroforestry in the state followed by ‘range and pasture land’ and ‘managing non-commercial forest land’ (both 84%), use on ‘commercial forest plantation’ (83%) and ‘fruit and nut orchards’ (61%). ‘Diversifies land use’ (25%), ‘enhanced productivity’ (18%), ‘aesthetics’ (13%) and ‘income diversity’ (13%) were the four most frequently cited potential advantages to practicing agroforestry. ‘Lack of information’ (28%), ‘lack of technical assistance’ (18%), ‘establishment costs’ (14%) and ‘not an established practice’ (14%) were the most frequently identified potential obstacles to practicing agroforestry. Respondents suggested there is great potential for application of agroforestry throughout the state, and non-industrial private forest land owners were selected for future study of this potential.

    Notes: Abstract A mail survey was conducted to gain understanding of the agroforestry practices of non-industrial private forest landowners (NIPF) in Washington State, located in the north-western USA. Although NIPF owners control 1.5 million hectares of the state's commercial forestland base, their diversity of forestland uses, land management practices and objectives as land managers are not well understood. Past NIPF surveys and anecdotal information suggest agroforestry is a major use of NIPF lands. We defined agroforestry as a potentially sustainable land use practice combining the deliberate growing of woody perennials with agricultural crops and/or animals. Objectives of this study were to: 1) determine the extent that agroforestry is used by Washington's NIPF owners, 2) develop insight into NIPF owners' motivations for practicing agroforestry, 3) describe the agroforestry practices within three distinct physiographic and agroecological zones in Washington, and 4) determine the agroforestry information needs of NIPF owners. The target population consisted of NIPF owners in 4 counties within each of the three regions. Response to the August 1990 mail survey was 63.5%, yielding 296 useable questionnaires. Fifty-seven percent of all respondents practice agroforestry. Forestland grazing is the most common agroforestry practice (39% of all respondents), followed by windbreaks (34%), harvest of special forest products (12%), livestock enrichment plantings for forage or shelter (7%), orchard grazing (5%), orchard intercropping (2%), and Christmas tree grazing (0.34%). The most frequent motives for owning land were passing land on to children (80%), keeping it natural and income from timber (both 72%). Respondents saw aesthetics (77%), increasing land unit income (74%), and water conservation (70%) as possible advantages of practicing agroforestry. High establishment costs (66%) and livestock damage to trees or crops (64%) were the most frequently selected potential disadvantages to practicing agroforestry. Lack of technical and educational support (67%) and lack of access to livestock/livestock facilities (58%) were disincentives to practicing agroforestry. Landowners are interested in learning more about agroforestry and how agroforestry techniques might be incorporated in their land management tool kit. A significant number of non-industrial private forest land owners in Washington believe that management of forestland, balancing conservation and production goals, can be furthered by suitable agroforestry practices.

    Notes: Abstract A corporate telephone operator and voice mail programmer was involved in a serious automobile accident resulting in left-arm amputation and through rehabilitation received a full left-arm prosthesis. Upon returning to work in her previous job capacity, some work activities and work area configurations were identified as problematic during task performance. Work methods and work area configuration were evaluated regarding their appropriateness for supporting return to work and long-term accommodation. Job activity analysis determined all reaches, clearances, and forces and their compliance with recommended criteria. A body part comfort/discomfort survey (BPCDS) was administered pre- and post-accommodation to elicit information regarding workplace problem areas and provide a measure to assess accommodation effectiveness. Workstation, support equipment, work area, seating, task assignments, and work methods were modified to more appropriately support operator task performance. Comparison of pre- and post-accommodation BPCDS indicates a significant reduction in operator discomfort with residual discomfort associated with the orthopedic prosthesis. This case study illustrates the use of the principles and techniques of industrial ergonomics to develop workplace accommodations. The area of ergonomics, medical ergonomics,is an example of the development of reasonable accommodations for physically challenged workers in the spirit of compliance with the Americans with Disabilities Act (ADA).

    Notes: Abstract The cohesive termini of the DNA genome of the lactococcal bacteriophage c2 were directly sequenced and appeared to be complementary, non-symmetrical, 9-nucleotide single-stranded, 3′ extended DNAs, with the following sequence: 5′-GTTAGGCTT-3′ 3′-CAATCCGAA-5′. DNA located on either side of the cohesive ends was sequenced and several repeats and a region with the potential for a DNA bend were found. Previously sequenced cos regions of 13 other bacteriophages were also examined for similar sequence features. All of the bacteriophages from gram-positive hosts had 3′ extended DNA termini, in contrast to the bacteriophages from gram-negative hosts, which had 5′ extended DNA termini. All bacteriophages had a region of dyad symmetry close to the cohesive termini. A 7.3 kb DNA fragment of the c2 genome containing the cos sequences was cloned; transduction experiments demonstrated that these cloned sequences could act as a substrate for packaging enzymes of phage c2.

    Notes: Some of the hazards encountered by process plant operators involve the operation of in-line valves to control, start, and to stop flow. Torque required to operate valves may vary according to valve wheel size, in-line pressure, and valve flange position (open/closed). This study determined how valve wheel size, in-line pressure and valve position (open/closed) affect torque required to actuate a valve. Data were gathered with each combination of size, pressure and position for 336 valves in an operating petrochemical process facility. The results indicate that the main effects of valve wheel size, the in-line pressure, and open/closed valve position significantly affect operational torque requirements. In addition, the interaction between position and pressure was significant for operational torque. The implication of these results is that operators are exposed to operational torque requirements that exceed maximum acceptable capabilities that have been determined in previous studies.

    Notes: The organization of a menu can significantly affect user response time when selecting targets from that menu. Previous empirical studies have used laboratory tests to suggest menu design rules that can optimize user response. This study applied the design rules to a menu used for display selection on an Energy Management System. In such a study, the total number of menu targets and the relationships among them is not variable, so some compromises must be made when applying the rules. This study produced a new menu that had measurable improvement in user response time over the existing menu. Design rules regarding grouping of targets and methods of organization were successfully applied during the menu redesign.
