Representation of transport: A Rural Destination Analysis

Moscovici’s social representations perspective is applied to a study of transport in a rural destination. The principles are demonstrated using empirical data from a questionnaire survey, developed following in-depth qualitative research. The data analysis strategy was founded on inductive reasoning, by employing cluster analysis and correspondence analysis. A social representations analysis demonstrates how individuals draw on socially accepted explanations of transport where they have little or no direct knowledge or experience of the actual transport modes (notably the alternatives to the car). By so doing, ideas are further perpetuated. Importantly there is ambiguity surrounding responsibility to take positive action yet a key to addressing transport issues is acknowledgement of responsibility.

Adventitious shoot propagation and cultural inputs in nursery production of a primocane-fruiting blackberry selection

Studies were conducted from January to October 2005 to determine the effect of root-cutting length on adventitious shoot yield and the management practices necessary to produce nurseryquality primocane-fruiting blackberry plants. The first portion of the study measured the average number of shoots produced from 7.6 cm- and 15.2 cm-long root cuttings of APF-44 blackberry—a primocane-fruiting genotype from the University of Arkansas breeding program. Cuttings were forced in a shallow bin containing a soilless potting medium. The average number of shoots per root cutting from 7.6 cm- and 15.2 cm- long root cuttings averaged 1.6 and 2.7 shoots per root cutting, respectively. Rooting percentage for collected shoots was nearly 100% regardless of root-cutting length source. A qualitative comparison of shoots from the two roots lengths was similar. The latter part of the study included various treatments on the rooted shoots that might affect the productivity and quality of the final product intended for nursery sales in early fall. With the aim of producing a flowering/fruiting shrub by late September, three treatments were applied: pot dimension, fertilizer rate, and shoot tipping. Fertilizer rate had the greatest impact of all treatments with the higher rate producing larger and more attractive plants. Above-normal summer/fall temperatures may explain lack of fruiting on APF-44 blackberries, but the dimension and size of some plants provided a portion of the intended aesthetic

Assessing sUASOperator Flight Behavior & Potential Interference with Aviation Operations in Controlled Airspace Using AeroScope

The information presented in this discussion details an ongoing study that measures the detection of small Unmanned Aircraft Systems (sUAS) in controlled airspace. Specialized equipment was used to collect telemetry data, which allowed researchers to determine sUAS position in relation to cooperative manned aircraft. Further analysis of possible “well-clear” or airspace violations was used to infer potential operator behaviors that may result in un-safe sUAS operations near controlled airports. The discussion will address concerns and propose possible mitigation strategies to decrease the probability of aircraft incursions near highly trafficked airports

ICESat Observations of Seasonal and Interannual Variations of Sea-Ice Freeboard and Estimated Thickness in the Weddell Sea, Antarctica (2003-2009)

Sea-ice freeboard heights for 17 ICESat campaign periods from 2003 to 2009 are derived from ICESat data. Freeboard is combined with snow depth from Advanced Microwave Scanning Radiometer for Earth Observing System (AMSR-E) data and nominal densities of snow, water and sea ice, to estimate sea-ice thickness. Sea-ice freeboard and thickness distributions show clear seasonal variations that reflect the yearly cycle of growth and decay of the Weddell Sea (Antarctica) pack ice. During October-November, sea ice grows to its seasonal maximum both in area and thickness; the mean freeboards are 0.33-0.41 m and the mean thicknesses are 2.10-2.59 m. During February-March, thinner sea ice melts away and the sea-ice pack is mainly distributed in the west Weddell Sea; the mean freeboards are 0.35-0.46 m and the mean thicknesses are 1.48-1.94 m. During May-June, the mean freeboards and thicknesses are 0.26-0.29 m and 1.32-1.37 m, respectively. The 6 year trends in sea-ice extent and volume are (0.023+/-0.051) x 10(exp 6)sq km/a (0.45%/a) and (0.007+/-1.0.092) x 10(exp 3)cu km/a (0.08%/a); however, the large standard deviations indicate that these positive trends are not statistically significant

Interjurisdictional Certification and Choice of Law

There is a story, probably apocryphal, that, at a 1970s conference discussing the great potential and even greater problems of some economically developing countries, a rather cynical American economist is supposed to have remarked that Brazil is the country of the future-and always will be. Some commentators believe that much the same could be said about the certification process, but with greater accuracy. Certification has beguiled and to some extent disappointed two generations of legal scholars.\u27 Intended to resolve problems that arise when a court of one jurisdiction must apply the law of another jurisdiction, certification is the process by which the first court may inquire of a court in the jurisdiction whose law is at issue for help in determining what the law is. The certification process is inherently attractive be-cause it eliminates the need for a court either to guess at another jurisdiction\u27s uncertain law or to refrain altogether from trying to apply that law. The difficulty that certification can ease typically arises in one of two situations. The first situation occurs when a federal court, for whatever reason, must identify and apply the substantive law of a state.Federal courts hearing diversity cases are the most likely to inquire into state law, but the problem can also arise when a federal court\u27s subject-matter jurisdiction is based on the presence of a federal question. The second situation occurs when a state court\u27s own conflict-of-laws rules direct it to apply the law of another state

Planning Approaches to Achieve a More Sustainable Travel Industry for Tourism in the UK - a Case Study

Transport is tourism's largest contributor to greenhouse gas (GHG) emissions. In the UK domestic tourism is dominated by car. The UK government is committed to a decrease in carbon emissions and to growing its tourism industry simultaneously. This paper explores the potential conflicts between the transport and tourism policy objectives and evaluates current policies. One obvious approach is to achieve a modal shift away from car to more sustainable public transport. The National Trust operates a large number of tourist attractions in the UK and has attempted to reduce the share of arrivals by car. The paper uses a large sample of visitors to National Trust properties as a case study to measure modal share and identify recent trends. The paper identifies those factors which have the greatest impact on modal choice and evaluates the effectiveness of policies aimed at achieving modal shift. The paper concludes with a discussion outlining the need for a co-ordinated, integrated approach to tourism mobility, highlighting the limitations arising from stakeholders, such as visitor attractions, operating in isolation

Standardization Roadmap for Unmanned Aircraft Systems, Version 2.0

This Standardization Roadmap for Unmanned Aircraft Systems, Version 2.0 (“roadmap”) is an update to version 1.0 of this document published in December 2018. It identifies existing standards and standards in development, assesses gaps, and makes recommendations for priority areas where there is a perceived need for additional standardization and/or pre-standardization R&D. The roadmap has examined 78 issue areas, identified a total of 71 open gaps and corresponding recommendations across the topical areas of airworthiness; flight operations (both general concerns and application-specific ones including critical infrastructure inspections, commercial services, and public safety operations); and personnel training, qualifications, and certification. Of that total, 47 gaps/recommendations have been identified as high priority, 21 as medium priority, and 3 as low priority. A “gap” means no published standard or specification exists that covers the particular issue in question. In 53 cases, additional R&D is needed. As with the earlier version of this document, the hope is that the roadmap will be broadly adopted by the standards community and that it will facilitate a more coherent and coordinated approach to the future development of standards for UAS. To that end, it is envisioned that the roadmap will continue to be promoted in the coming year. It is also envisioned that a mechanism may be established to assess progress on its implementation
