Big Sur Visitor Characteristics and Wildland Fire Recreational Constraints

A study conducted with visitors to the Big Sur region of California during summer 2002 is presented. An onsite survey was administered to visitors to the U.S. Forest Service and California State Parks day-use and overnight facilities. Recreational constraints owing to wildland fire and fire management are detailed along with the effects of activity type, visitor demographics and other characteristics, and views of these constraints. Differences primarily exist in views of constraints related to regulations

Complete Findings: Survey on Public Opinions and Attitudes on Outdoor Recreation in California: 2009

A Statewide Comprehensive Outdoor Recreation Plan (SCORP) is required of every state in order to be eligible for grants from the Land and Water Conservation Fund Act. The LWCF Act requires the SCORP to include the following: a) the name of the state agency with authority to act for California in dealing with the Secretary of the Interior for the purposes of the LWCF Act, b) an evaluation of the demand for and supply of the outdoor recreation resources and facilities in the state, c) a program for the implementation of the Plan, d) certification by the governor that ample opportunity for public participation has taken place in Plan development, e) other necessary information as may be determined by the Secretary. The 2007 Survey on Public Opinions and Attitudes on Outdoor Recreation in Californiaincluded a telephone survey, an adult mail survey, youth focus groups, and a youth mail survey in order to provide a comprehensive view of the outdoor recreation patterns and preferences of Californians. The measurement of various items on the surveys was changed substantially from earlier surveys (2002, 1997, etc.) in order to attempt to increase response rates, improve the readability of the survey instruments, and to provide a contemporary view of outdoor recreation in California. For example, the 2008 telephone survey focused on physical activity that occurs in parks. Similarly, the adult mail survey added components on leisure constraints, issues regarding global warming, and enhanced measures of latent demand for recreation activities. Finally, the youth survey addressed issues important to California’s youth and included items regarding the recently developed and Governor endorsed California Children’s Outdoor Bill of Rights (COBR). The sampling procedures resulted in a telephone survey of 2,780 Californians of which, 1,227 also completed a mail/online survey. In addition, 397 youth participated in the youth mail survey

Recreation and Fire Management in Urban National Forests: A Study of Manager Perspectives

The purpose of this study was to understand U.S. Department of Agriculture Forest Service public land managers’ perceptions of fire management and recreational use in urban national forests of the United States. An online survey was used to understand managers’ perceptions of (a) the degree to which the presence of recreational activities and experiences are a constraint to fire management, (b) the degree to which fire management and suppression activities influence the quality of a visit to a recreation site, and (c) the relationships between fire management and recreation constraints. In all, 62 district rangers within urban national forests were asked to complete an online survey, and 33 responded (53 percent). The following items were thought to moderately to severely impact the managers’ ability to manage fire: increased urban development, budget constraints, accumulation of burnable fuels, effect of smoke on visitors, increased visitation, and the lack of trained personnel. In addition, most managers believed that recreational use of day-use areas, trails, campgrounds, and access roads conflicted moderately or slightly with fire management decisions. Over 70 percent of respondents indicated that mountain bikes on unauthorized trails, vandalism, litter, encroachment from surrounding farmland, unauthorized grazing, and, unauthorized logging did not have an impact on fire management decisions. Generally respondents did not perceive management factors as limiting visitors’ pursuit of recreation activities. In addition, most managers identified the occurrence of various management activities (e.g., campground closures from smoke, trail closures owing to wildland fires, fire suppression, etc.) as slightly to not limiting at all

Place Attachment and Recreational Constraints Relating to Fire Management

This paper presents a study of visitors to the Big Sur region of California during summer 2001. An onsite survey was administered to visitors to USDA Forest Service day-use areas and at developed campgrounds. Place attachment, observations relating to fires and fire management, and perceived recreational constraints owing to wildland fire and fire management are examined. The results indicate that place dependence and place identity influence some perceived constraints and observations of fire conditions. A discussion of the findings is provided, emphasizing the importance of managers’ understanding of visitors’ perceptions relating to fire and fire management

Double-Blind Phase III Trial of Adjuvant Chemotherapy With and Without Bevacizumab in Patients With Lymph Node-Positive and High-Risk Lymph Node-Negative Breast Cancer (E5103)

Purpose Bevacizumab improves progression-free survival but not overall survival in patients with metastatic breast cancer. E5103 tested the effect of bevacizumab in the adjuvant setting in patients with human epidermal growth factor receptor 2-negative disease. Patients and Methods Patients were assigned 1:2:2 to receive placebo with doxorubicin and cyclophosphamide (AC) followed by weekly paclitaxel (arm A), bevacizumab only during AC and paclitaxel (arm B), or bevacizumab during AC and paclitaxel followed by bevacizumab monotherapy for 10 cycles (arm C). Random assignment was stratified and bevacizumab dose adjusted for choice of AC schedule. Radiation and hormonal therapy were administered concurrently with bevacizumab in arm C. The primary end point was invasive disease-free survival (IDFS). Results Four thousand nine hundred ninety-four patients were enrolled. Median age was 52 years; 64% of patients were estrogen receptor positive, 27% were lymph node negative, and 78% received dose-dense AC. Chemotherapy-associated adverse events including myelosuppression and neuropathy were similar across all arms. Grade ≥ 3 hypertension was more common in bevacizumab-treated patients, but thrombosis, proteinuria, and hemorrhage were not. The cumulative incidence of clinical congestive heart failure at 15 months was 1.0%, 1.9%, and 3.0% in arms A, B, and C, respectively. Bevacizumab exposure was less than anticipated, with approximately 24% of patients in arm B and approximately 55% of patients in arm C discontinuing bevacizumab before completing planned therapy. Five-year IDFS was 77% (95% CI, 71% to 81%) in arm A, 76% (95% CI, 72% to 80%) in arm B, and 80% (95% CI, 77% to 83%) in arm C. Conclusion Incorporation of bevacizumab into sequential anthracycline- and taxane-containing adjuvant therapy does not improve IDFS or overall survival in patients with high-risk human epidermal growth factor receptor 2-negative breast cancer. Longer duration bevacizumab therapy is unlikely to be feasible given the high rate of early discontinuation

A View of Tropical Cyclones from Above: The Tropical Cyclone Intensity Experiment

Tropical cyclone (TC) outflow and its relationship to TC intensity change and structure were investigated in the Office of Naval Research Tropical Cyclone Intensity (TCI) field program during 2015 using dropsondes deployed from the innovative new High-Definition Sounding System (HDSS) and remotely sensed observations from the Hurricane Imaging Radiometer (HIRAD), both on board the NASA WB-57 that flew in the lower stratosphere. Three noteworthy hurricanes were intensively observed with unprecedented horizontal resolution: Joaquin in the Atlantic and Marty and Patricia in the eastern North Pacific. Nearly 800 dropsondes were deployed from the WB-57 flight level of ∼60,000 ft (∼18 km), recording atmospheric conditions from the lower stratosphere to the surface, while HIRAD measured the surface winds in a 50-km-wide swath with a horizontal resolution of 2 km. Dropsonde transects with 4–10-km spacing through the inner cores of Hurricanes Patricia, Joaquin, and Marty depict the large horizontal and vertical gradients in winds and thermodynamic properties. An innovative technique utilizing GPS positions of the HDSS reveals the vortex tilt in detail not possible before. In four TCI flights over Joaquin, systematic measurements of a major hurricane’s outflow layer were made at high spatial resolution for the first time. Dropsondes deployed at 4-km intervals as the WB-57 flew over the center of Hurricane Patricia reveal in unprecedented detail the inner-core structure and upper-tropospheric outflow associated with this historic hurricane. Analyses and numerical modeling studies are in progress to understand and predict the complex factors that influenced Joaquin’s and Patricia’s unusual intensity changes

The state of the Martian climate

60°N was +2.0°C, relative to the 1981–2010 average value (Fig. 5.1). This marks a new high for the record. The average annual surface air temperature (SAT) anomaly for 2016 for land stations north of starting in 1900, and is a significant increase over the previous highest value of +1.2°C, which was observed in 2007, 2011, and 2015. Average global annual temperatures also showed record values in 2015 and 2016. Currently, the Arctic is warming at more than twice the rate of lower latitudes
