Timber marketing in a revitalised north Queensland forest industry: overview of major issues
No full textAs the harvest of timber from native forests has contracted in north Queensland, the traditional supply chain from forest to final consumer has to a large extent broken down. As a result, landholders and non-farmer investors cannot assume that timber markets will automatically exist when they have trees ready for harvest A wide variety of research has been carried out that is relevant to timber marketing in north Queensland. Surveys of timber millers, cabinet~makers and their staff, and purchasers of timber products, as well as financial modeling of timber milling, have been used to derive information about timber markets in north Queensland. Research has been undertaken on supply chain and market analysis, attitudes of timber processors and final consumers, institutional arrangements for market facilitation and market development
Simulation of management strategies for feral pig control in the wet tropics
Get PDFThis paper reports the development and application of the Feral Pig Management Model (FPMM). The model is used to examine the affect that alternative management strategies have on a feral pig population and thus the likely economic effect, over a 20-year planning horizon. The model is used to undertake a cost-benefit analysis based on the cost of control versus the benefit associated with the reduction of feral pig damage to agricultural crops. A number of alternative strategies are compared assuming the same types and levels of control measures (shooting, poisoning and trapping) applied. The research identified that irrespective of 'strategy configuration', more frequent control appears to have a higher ranking (lower total costs). Isolated knockdowns appear to have little impact on the feral pig population in the medium to long-term. Regular continuing control at high levels is identified as the optimal control strategy
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
The role of government policy in facilitating investment in forestry – local and national issues
Get PDFThis paper examines some issues associated with taxation, carbon trading and biofuels as ‘global’ policies. Whilst taxation is a national concern, it can be used as a tool to enhance the effectiveness of carbon trading as means of achieving reduced CO2 emissions. Taxation is used to provide taxation benefits for research and development of improved technology, reducing investment cost by greater depreciation rates and investment incentives to mention a few. Taxation does increase the level of plantation establishment and in Australia the use of Managed Investment Schemes have proven to be particularly successful. Other sectors of the community question whether the increased establishment of monoculture plantations is a success at the local level. The need to do something about climate change has been accepted internationally although what and how to do it is still subject to much debate. This paper highlights that although a common international approach is called for, some issues such as different trading systems and criteria create ambiguity. The European Union’s call for greater use of biofuels is visited but regarded by some as an example of well intentioned policy being adopted but for various reasons has created problems such as deforestation on a localised basis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
