An Investigation into Attitudes towards Recycling CCA Treated Lumber
No full textThis research examines the effects of evaluations, beliefs, subjective norms, and perceived behavioral control on the contractor's decision intention to recover used CCA lumber. The purpose of this research was to determine the factors that affect recovery. This research proposes that a contractor's decision intention to recover is affected by evaluations, beliefs, subjective norms, and perceived barriers to recovery.
The study included a mail questionnaire that was sent to over 2,800 contractors. The questionnaire was used to collect both demographic data and an evaluation of the factors believed to affect the recovery of CCA treated lumber. Data was collected primarily through the mail survey, where participants rated the factors believed to affect the recovery of spent CCA lumber.
Extrapolation indicates that nearly 2.4 million cubic meters of treated lumber were removed in 1999 from the demolition of decks. It was also discerned that only two of the respondents recovered used CCA lumber on a full-time basis. Additionally, there appears to be a lack of knowledge regarding the chemical components of CCA treated lumber, the proper disposal methods, and handling of the product. This has profound strategic implications for not only the wood treating industry but other industries as well.
The second phase of the research utilized ordinary least squares regression and a structural equation modeling program to model the factors concerning the contractors' decision intention to recover. The findings indicate that contractor beliefs and components of perceived behavioral control are the primary drivers in the contractor's decision intention to recover. Regarding beliefs, the findings indicate that contractors have a minimal belief that the recovery of the CCA lumber is necessary. This indicates that a marketing communications program should be developed to address the necessity and benefits of recovery.
Recovery facilities and programs were found to be nonexistent and will have to be developed in order to facilitate recovery. Concerning programs, the overwhelming response was that some type of financial incentive would have to be incorporated to initiate recovery. In conjunction with the development of programs, recovery facilities will have to be developed that are convenient for the contractor to dispose of the used lumber.Ph. D
Assessing the Availability of Wood Residues and Residue Markets in Virginia
Full text linkA statewide mail survey of primary and secondary wood product manufacturers was undertaken to quantify the production and consumption of wood residues in Virginia.
Two hundred and sixty-six wood product manufacturers responded to the study and they provided information on the production, consumption, markets, income or disposal costs, and disposal methods of wood residues. Hardwood and pine sawmills produce approximately 66 percent of Virginia's wood residues. Virginia's wood product manufacturers produce three primary residues: chips, bark, and sawdust. These three residues comprised nearly 83 percent of Virginia's total residue production in 1996. Approximately 200,000 tons or 6 percent of Virginia's wood residues appear not to have adequate markets.
A second survey was directed to all municipal waste, construction and demolition, and "other" waste facilities in Virginia. The focus of this survey was to quantify the volume of solid wood residues received at the facilities. In addition, the study was conducted to ascertain tipping fees, did the landfill(s) actively market wood residues, were wood residues recycled, were wood residues restricted from being landfilled, and disposal methods for wood residues. Additionally, the survey was conducted to determine the type of waste facility operated, the quantity of all wastes directed to each landfill, and tipping fees.
Seventy-five respondents provided information on the total and solid wood waste volumes received at their respective facilities, recycling efforts, and disposal practices. Approximately 689,000 tons of solid wood, or 8 percent of all wastes, was received at Virginia's landfills in 1996. Virginia's waste facilities reported processing or recycling approximately 406,000 tons or 59 percent of the solid wood received in 1996.Master of Scienc
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
