Spatial and temporal definition of Ochlerotatus camptorhynchus (Thomson) (Diptera: Culicidae) in the Gippsland Lakes system of eastern Victoria

The confirmed vector of Ross River virus, Ochlerotatus camptorhynchus (Thomson), is the dominant mosquito species inhabiting saline marshes in coastal Victoria. This paper re-examines previously published data on Oc. camptorhynchus, plus additional data collected since that time, and provides greater spatial and temporal definition of Oc. camptorhynchus numbers at seven sites across the Gippsland Lakes system of eastern Victoria. A total of 357 672 Oc. camptorhynchus was captured from 1188 trap-nights across the seven trap sites during trapping seasons from 1990 to 2001. The  dominance of Oc. camptorhynchus across the seven sites averaged 75%, with significant differences in mean abundance of Oc. camptorhynchus found between all trap sites. Significant differences in monthly abundance of Oc. camptorhynchus were observed for Wellington Shire. Increase in populations of Oc. camptorhynchus was associated with increases in rainfall at all trap sites, higher minimum temperatures at two of the seven trap sites, and wind speed at one trap site. Prioritisation of mosquito control may be applied based on spatial and temporal factors according to the findings of this study.

Lymphedema after complete axillary node dissection for melanoma: assessment using a new, objective definition

Objectives: The objectives of this study were to define appropriate criteria for assessing the presence of lymphedema, and to report the prevalence and risk factors for development of upper limb lymphedema after level I-III axillary dissection for melanoma.
Summary Background Data: The lack of a consistent and reliable objective definition for lymphedema remains a significant barrier to appreciating its prevalence after axillary dissection for melanoma (or breast carcinoma).
Methods: Lymphedema was assessed in 107 patients (82 male, 25 female) who had previously undergone complete level I-III axillary dissection. Of the 107 patients, 17 had also received postoperative axillary radiotherapy. Arm volume was measured using a water displacement technique. Change in volume of the arm on the side of the dissection was referenced to the volume of the other (control) arm. Volume measurements were corrected for the effect of handedness using corrections derived from a control group. Classification and regression tree (CART) analysis was used to determine a threshold fractional arm volume increase above which volume changes were considered to indicate lymphedema.
Results: Based on the CART analysis results, lymphedema was defined as an increase in arm volume greater than 16% of the volume of the control arm. Using this definition, lymphedema prevalence for patients in the present study was 10% after complete level I-III axillary dissection for melanoma and 53% after additional axillary radiotherapy. Radiotherapy and wound complications were independent risk factors for the development of lymphedema.
Conclusions: A suggested objective definition for arm lymphedema after axillary dissection is an arm volume increase of greater than 16% of the volume of the control arm.

Expanding the buyer-supplier relationship definition: its antecedents and relationship with performance outcomes

This paper aims to contribute to current buyer-supplier relationship literature through conceptually examining associations between the buyer-supplier relationship itself, organisational antecedents and the external environment. Whilst the presence of relational components within the transaction has been acknowledged, there is, has been, and remains, great difficulty in defining and understanding the dynamics of the buyer-supplier relationship itself. This study aims to address current research limitations and further develop understanding of the dynamics between buyers and suppliers, through a grounded theory research approach. The core focus is to understand the basic motivations and considerations for organisations when potentially considering relationship development with a trade partner. Thus, the organisational attributes that must be apparent and those preferred by potential trade partners are studied. Development of a conceptual model leads to the recognition of three key research questions that are to be addressed in future empirical investigation of the model.

Transnational citizenship: problems of definition, culture and democracy

There is widespread disagreement over whether transnational citizenship provides defensible extensions of, or meaningful complements to, national citizenship. A significant strand of criticism relies upon empirical arguments about political motivation and the consequences of transnationalism. This paper addresses two questions arising from empirical arguments relating to the nation state and democracy. Do the alleged cultural requirements for effective political action provide an insuperable barrier to transnational citizenship? Does transnational citizenship necessarily require a commitment to transnational democracy? I argue that these largely empirical criticisms do not succeed in casting doubt upon the normative plausibility or practical viability of transnational projects. On the first question, I point to a growing transnational political culture that serves to motivate transnational citizens. On the second question, I argue for a legitimate category of transnational citizenship that, although inspired by cosmopolitan morality, is different from it, and that does not require transnational democracy.

A new definition of 'Museum'

At the national AGM of Museums Australia held on 22 Mar ch 2002, our association adopted a new definition of ‘museum’. This article aims to provide members and other readers with an understanding of the background to the change, and the potential offered to our sector by the new definition.

Interlink decision making index (IDMI) -- a simple tool/concept to assist decision making for sustainability Part 1: definition of IDMI

There is an apparent gap between the LCA or other assessment's outcomes and its effective application in the decision making process. It is needed to provide to the decision makers a simple, less human interfered mechanism that integrates all the key criteria (environmental, economic, technical and safety etc.). The proposed index: Interlink Decision Making Index (IDMI) has all these features: simple, interlink (all criteria) and automatically and quantified influence of critical criteria (ie. no human weighting needed) and is able to assist the multi-criteria decision making for sustainability based on the outcomes of specific assessments (eg. LCA, ElA etc.). The index represents a pure numerical value and does not necessarily have any physical meanings, but it reflects the total merits of a particular option once the normal decision making criteria and (up to two) critical criteria (CC) have been chosen. Then, without arbitrarily weighting process, the comparison and selection of the best possible option, ie. decision can be made based on the derived IDMI results. Two hypothetical examples are presented in part 2 of the paper to demonstrate the application of the IDMI concept and it's differences with the traditional "tabular method" in the decision making process.

The relationship between innovation and entrepreneurship : easy definition, hard policy

The paper argues that innovation is the combination of an inventive process and an entrepreneurial process to create new economic value for defined stakeholders and focuses on the policy implications of this duality. Attention is concentrated on summarising the entrepreneurial process and its importance to innovation policy and avoids any detailed elaboration of the invention process. A very brief overview of the invention process is followed by a moderately detailed summary of Hindle's (2008) model of entrepreneurial process. With an understanding and formal articulation of entrepreneurial process it becomes possible to focus on the key issues that ought to inform the development of innovation policy. These key issues are discussed and the paper concludes where it began by emphasising the need to build innovation policy on the explicit recognition that innovation results from the blending of two processes, invention and entrepreneurship, and that viable innovation policy can never be created unless entrepreneurial process is properly understood and addressed.

Definition and quantification of assets

The word ‘asset’ was originally taken into the English language, from the Latin ‘ad satis’ and French ‘asez’, as a term used at law meaning sufficient estate or effects to discharge debts. It later came to be used in the sense of property available for the payment of debts. Assets were understood to be property (objects owned and rights of ownership) that could be exchanged for cash. The importance of factual knowledge of the money equivalents of property and debts, in managing mercantile affairs, was emphasised in accounting manuals during the eighteenth and nineteenth centuries. The rights of investors and creditors to factual up-to-date information about the financial state of affairs of companies, given the advent of limited liability, underscored the early company legislation that required the preparation and auditing of statements of property and debts. During the latter part of the nineteenth century the emphasis in accounting moved away from assets as exchangeable property to assets as deferred costs. Expectations took the place of observables. The abstract (expectational) notion of assets as ‘future economic benefits’ was embraced by accountants in the absence of rigorous definitions of the elements and functions of dated statements of financial position and performance. Assets are quantified financially by a heterogeneous mass of potentially inconsistent rules that, by and large, have no regard for the empirical nature of measurement. Consequently, accountants have failed to provide the community with up-to-date factual information about the financial state of affairs and performance of business entities - and, hence, with an informative basis for financial action.

A doctorate by definition : exploring possibilities and opportunities in education

The author provides a diagram and table which reflect his conceptualisation of issues surrounding the definition of a doctorate. Two broad questions frame this characterisation: (i) what defines the doctorate? and (ii) where to now? In relation to the first question the author contends that the resources available to students, supervisors and institutions significantly influence what is regarded as a 'good' doctorate and the 'protection' of this standard. An overlapping set of issues is identified in response to the question 'where to now'? These are expressed as strategies in negotiating doctorate definitions and futures; some more reminiscent of times past and some cognisant of prevailing conditions, while others offer a qualitatively different strategy that explores (or generates) possibilities and opportunities within the parameters of the doctorate.

Definition of homelessness changes but problems remain

According to the best estimates at the time, almost 105,000 Australians were homeless on census night in August 2006. This promoted then Prime Minister Kevin Rudd to make the ambitious commitment to accommodate all people sleeping rough and halving the number of homeless in Australia by 2020.
