Clear purpose or sheer survival? National ministerial leadership across multiple arenas

Day-to-day political life for the most senior national politicians can be very pressurized and exposed. How they as individuals cope with constant challenges and make the most of opportunities for leadership is an under researched area. This is addressed in this interpretive study of the personal accounts of a small group of prominent U.K. politicians as they reflect, soon after leaving office, on their experiences as national ministers. The article connects generic leadership theory around practice and purpose with political leadership studies as a basis for a thematic analysis of ministers’ experiences across three key prominent arenas of ministerial life: relationships with the Prime Minister’s office, within their departments, and with their constituencies. Analysis of findings leads to a proposed analytical framework of active leadership in their everyday experience. The article concludes that active leadership practice is difficult but possible for leading national politicians

A Coordinated Effort to Manage Soybean Rust in North America: A Success Story in Soybean Disease Monitoring

Existing crop monitoring programs determine the incidence and distribution of plant diseases and pathogens and assess the damage caused within a crop production region. These programs have traditionally used observed or predicted disease and pathogen data and environmental information to prescribe management practices that minimize crop loss (3,69). Monitoring programs are especially important for crops with broad geographic distribution or for diseases that can cause rapid and great economic losses. Successful monitoring programs have been developed for several plant diseases, including downy mildew of cucurbits, Fusarium head blight of wheat, potato late blight, and rusts of cereal crops (13,36,51,80)

Streamlining Local-Let Federal-Aid Transportation Processes in Ohio

SJN 135519Ohio\u2019s local public agencies (LPAs) administer an average of $335 million of Federal-aid projects annually through the ODOT local-let program. ODOT has made significant strides to improve the efficiency of its Federal-aid program delivery process for LPA-administered projects in recent years. The objective of this research was to undertake a review of ODOT\u2019s local-let program requirements in the areas of real estate/right-of-way, construction contract administration, and finance to determine if any additional process streamlining could be achieved. This review found that a vast majority of activities LPAs are required to perform as part of Federal-aid project administration were consistent with applicable Federal requirements. Outreach to Ohio\u2019s LPAs and other State DOTs yielded valuable insight on best practices and potential strategies for streamlining the administration of Federal-aid projects by Ohio\u2019s LPAs at both the project and program level. Eight recommendations for streamlining are presented; implementation of these recommendations is expected to result in improvements to the delivery of ODOT\u2019s local-let program, including more efficient use of ODOT and LPA resources, cost and time savings for project delivery, and greater clarity on program performance

A Study of Neutron Proton Charge Exchange Scattering in the Momentum Range 50 - 200 GeV

It is proposed to measure the neutron-proton charge-exchange cross-section in an on-line counter experiment for four-momentum transfers between .002 and 1.0 (GeV/c){sup 2}. The experiment will be performed in an intense neutron beam with a continuous momentum spectrum; data will be taken simultaneously for all momenta between 50 and 200 GeV/c. At a beam intensity of 10{sup 7} neutrons/pulse, the true data-collection rate will be about .5 per pulse. Approximately 90,000 events will be obtained. The vector momenta of both outgoing particles are measured, resulting in a 3-constraint fit. The two-body topology allows a large rejection of background by the counter logic

Effectiveness of Wildlife Mitigation Treatments Along the Nelsonville Bypass

SJN 135024The Nelsonville Bypass is a 9 mile stretch of U.S. Route 33 that runs through the Wayne National Forest, an area high in species diversity and home to several threatened and endangered species. The motorist safety, economic and conservation values of building effective mitigation features that reduce vehicle-wildlife collisions along the bypass have been nationally recognized. Mitigation features include: high and low fencing to reduce wildlife trespass into the right-of-way (ROW), uni-directional jump outs for wildlife exit from the ROW, underpasses and ecopassages to maintain habitat connectivity across the highway, high-mast lighting to lure bats above traffic flow, and replacement of wetlands and bat roosting habitat. Our two-year study employed road surveys, continuous monitoring of jump outs and wildlife passages, population estimations, detailed mapping of fence structures and breaches, and radio telemetry of an endangered target species. Road surveys of the bypass and control highways revealed that the mitigation structures reduced deer-vehicle collisions, but collisions still occurred on the bypass. Although, generally well-constructed, we identified several ways in which the mitigation features could be made more effective. Placement of fencing near the outer boundary of the ROW made it vulnerable to damage from erosion and tree falls, and isolated high-quality habitats within the ROW. Placement of the fence within 30-50 ft. of the roadway on less rugged terrain away from the forest would likely reduce costs of construction and maintenance while allowing wildlife access to habitat within the ROW. We also recommended regular maintenance inspections and mowing on both sides of the fencing. Jump outs were effective uni-directional exits, but wildlife, particularly deer, were not compelled to exit the expansive area within the ROW fencing. Placement of the fence with jump outs closer to the road would reduce habitat within the fence and combined with traffic noise may increase jump out use. Large wildlife underpasses and crossings were well used by a variety of mammal species. Smaller mammals used the small wildlife ecopassages. Reptiles and amphibians avoided the use of underpasses and road mortality rates of amphibians were high on Ohio State Route 78 (tributary road) near wetlands. Placement and passage design were contributing factors to high amphibian mortality. Radio-tracking of rattlesnakes discovered that snakes easily trespassed the small wildlife fencing and used the habitat within the ROW, likely because it was warmer than the surrounding forested habitat. No road mortality or attempted road crossings by rattlesnakes were detected. Finally, while bats foraged near the lights, most species were detected with equal frequency at different heights under the lighting. Our report details these findings and provides additional recommendations to improve design and construction of wildlife mitigation features both along the Nelsonville Bypass, and for future design of mitigation features for roadways in high-density wildlife areas
