(2001) for the selection of reliable halo white dwarfs (WDs). The local WD space density we estimate is ρWD ≃ 1÷2 × 10-5 M⊙ pc-3, which is about an order of magnitude smaller than the value derived in Oppenheimer et al. (2001), and is consistent with the values obtained from recent reanalyses of the same data. Our result, which corresponds to a fraction of 0.1% ÷ 0.2% of the local dark matter, does not support the scenario suggested by microlensing experiments that ancient cool WDs could contribute significantly to the dark halo of the Milky Way. 2013-05-10T03:57:04.483Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:15522 We describe a quantum electromechanical system comprising a single quantum dot harmonically bound between two electrodes and facilitating a tunneling current between them. An example of such a system is a fullerene molecule between two metal electrodes [Park et al., Nature 407, 57 (2000)]. The description is based on a quantum master equation for the density operator of the electronic and vibrational degrees of freedom and thus incorporates the dynamics of both diagonal (population) and off diagonal (coherence) terms. We derive coupled equations of motion for the electron occupation number of the dot and the vibrational degrees of freedom, including damping of the vibration and thermo-mechanical noise. This dynamical description is related to observable features of the system including the stationary current as a function of bias voltage. 2013-05-09T10:51:21.509Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:25403 An experimental documentary that explores the traces of Palermo’s history visible in its architecture and street life, and the way history can be constructed on screen.

The present study was designed to extend this research and examine the relationship between information acquisition strategies and decisionmaking amongst experienced and inexperienced practitioners. For the purposes of the research, the aviation context was selected, since it provided a naturalistic decision context, and it was possible to assess operator experience reasonably accurately. Fifty pilots, of whom 39 were classified as inexperienced, engaged in a series of scenarios involving an in-flight diversion. The scenarios were computerbased, and were counterbalanced both in terms of the context for the flight and in the type of information acquisition strategy involved. The three information acquisition strategies were consistent with either the frequency, majority of confirming decisions, or elimination by aspects of decision heuristics. A fourth scenario enabled participants to select the strategy of their choice, once they had completed the preceding scenarios. The results revealed differences between experienced and inexperienced operators in both the accuracy and the efficiency with which decisions were made. The results have important implications for decisionmaking in advanced technology environments. 2013-05-09T09:35:20.517Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:25430 'Knit-face "toys" with the idea of the portrait in a pluralist society.

European Union enlargement challenges this mindset by legally transforming 'national territory' into 'supranational' real property or even opening the possibility of restitution claims by 'foreigners'. In the Polish and Czech cases this is highly contentious, principally due to the prospect of Germans and/or Austrians obtaining land. Rather than representing prosaic exchange among neutral economic agents the issue is embroiled in a complex of political and emotive influences, with historical roots that run deeper than the communist era. Realisation of a common European legal order is accompanied and to some extent hindered by misgivings about a liberal space of free access, unrestricted capital movement and no discrimination on grounds of nationality. 2013-05-09T09:34:30.800Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:24894 11 page(s) 2013-03-20T11:10:17.540Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:24895 12 page(s) 2013-03-20T11:10:13.522Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:24507 The purpose of this study was to test the ability of students in scoring an observational tool for measuring physical disability, the Motor Assessment Scale (MAS) for stroke, before and after training in order to establish whether current training and testing procedures for students are adequate. Sixteen students were tested using items 1-8 of the MAS before and after training. The students were required to observe the videotaped performance of four patients with stroke being assessed using the MAS and to score the performance of each patient. After training, the students were retested. The percent exact agreement between students' scores and criterion scores was calculated for each student and for each item. They were then compared before and after training using Student t test. When compared with criterion, the students achieved a mean of 79.6% (standard deviation, 10.8%) exact agreement before training and 83.9% (standard deviation, 6.7%) after training. While this increase in percent exact agreement was not statistically significant (p = 0.10), all students reached at least 75% exact agreement after training. Percent exact agreement on the items increased significantly (p = 0.03) so that seven of the eight items reached at least 75% exact agreement after training. The results of this study suggest that training is important to ensure that all students reach an acceptable standard. 2013-03-06T08:03:50.366Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:24512 Objective To evaluate the effectiveness of 2 rehabilitative approaches for improving paretic limb reaching by chronic stroke subjects. Design Pre- and posttest reaching to targets ipsilateral, midline, and contralateral to the impaired side. Setting Training in subjects' homes; testing in a laboratory setting. Participants Twelve poststroke volunteers were matched using the Motor Assessment Scale (MAS) and then were randomly assigned to 1 of 2 training conditions. Subjects were subsequently categorized as at a high or low functional level, using the reaching pretest movement time scores. Interventions Training (trunk unrestrained) using the paretic limb was 4 weeks (12 sessions). Task-related training (TRT) involved reaching to objects placed across the workspace. Progressive resistive exercise (PRE) involved whole-arm pulling against resistive therapeutic tubing in planes and distances similar to that in TRT. Main outcome measures Kinematic analysis of arm trajectory and trunk motion using the Peak Performance System, as well as scores on the MAS and the Rivermead Motor Assessment (RMA). Results For low-level groups, TRT resulted in increased substitutive trunk use at the target ipsilateral to the moving arm, and for midline and contralateral targets after PRE. Only low-level, TRT subjects straightened hand paths, which suggested better coordination of elbow-shoulder motion, and improved on the RMA. High-level subjects decreased trunk use at ipsilateral target after PRE, which was not observed after TRT. No significant differences between training conditions were found for other kinematic variables. Conclusions Training benefits appear to depend on initial level of functioning. Although compensatory trunk use was evident, low-level subjects seemed to benefit most from TRT. High-level subjects, whose kinematics showed fairly normal movement organization, demonstrated less compensatory movement after PRE. 2013-03-06T08:03:37.752Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:24428 The role of two binocular cues to motion in depth - changing disparity (CD) and interocular velocity difference (IOVD) - was investigated by measuring stereomotion speed discrimination and static disparity discrimination performance (stereoacuity). Speed discrimination thresholds were assessed both for random dot stereograms (RDS), and for their temporally uncorrelated equivalents, dynamic random dot stereograms (DRDS), at relative disparity pedestals of -19, 0, and +19 arcmin. While RDS stimuli contain both CD and IOVD cues, DRDS stimuli carry only CD information. On average, thresholds were a factor of 1.7 higher for DRDS than for RDS stimuli with no clear effect of relative disparity pedestal. Results were similar for approaching and receding targets. Variations in stimulus duration had no significant effect on thresholds, and there was no observed correlation between stimulus displacement and perceived speed, confirming that subjects responded to stimulus speed in each condition. Stereoacuity was equally good for our RDS and DRDS stimuli, showing that the difference in stereomotion speed discrimination performance for these stimuli was not due to any difference in the precision of the disparity cue. In addition, when we altered stereomotion stimulus trajectory by independently manipulating the speeds and directions of its monocular half-images, perceived stereomotion speed remained accurate. This finding is inconsistent with response strategies based on properties of either monocular half-image motion, or any ad hoc combination of the monocular speeds. We conclude that although subjects are able to discriminate stereomotion speed reliably on the basis of CD information alone, IOVD provides a precise additional cue to stereomotion speed perception. 2013-02-27T05:20:58.366Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:24211 The federal leader of the Australian Labor Party (ALP) Mark Latham advocates a “new politics”, where the establishment is “given hell”, and the privileges of the “insiders” of the system cracked down upon. His bold declaration to bring Australian forces serving in Iraq home by Christmas 2004 provoked not just speculation that he was pursuing a more isolationist foreign policy, but also that the party would be moving in a radically different direction under Latham’s leadership. This paper looks at the reality of the direction of the Latham-led ALP in the early part of his leadership as well as likely future directions. It begins by looking at the trajectory of the party in the years since losing office in 1996, and concludes that the economic neo-liberal and socially conservative path taken by former leaders Kim Beazley and Simon Crean is being continued under Latham, with the addition of a populist twist. Latham’s “new politics” and his “democratic reform” proposals are critically assessed. Latham’s grand ambitions for a “new politics” must be considered alongside a number of old dilemmas faced by the ALP. The question of how distinct is Labor’s policy agenda from that of the Coalition will continue to dog Latham just as it did his predecessors. How much can Labor intervene in the market to improve the lot of the majority when it believes that the ability of nation-states to challenge global economic forces is severely limited? The issue of how much it can deliver to its more disadvantaged constituents without alienating business groups has been a perennial thorn in the side of Labor in government, and all the evidence suggests that this dilemma will be even more sharply posed under a Latham administration. 2013-02-18T06:32:45.853Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:24219 20 page(s) 2013-02-18T06:32:30.312Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:24223 Book review of "It’s Time Again: Whitlam and Modern Labor", Jenny Hocking and Colleen Lewis (eds), Armidale: Melbourne Publishing Group, 2003, ISBN 0958093849. 2013-02-18T06:32:19.713Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:24224 6 page(s) 2013-02-18T06:32:19.330Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:24276 5 page(s) 2013-02-18T06:30:22.507Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:24277 6 page(s) 2013-02-18T06:30:17.165Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:24243 Be the change that you want to see in the world Mahatma Gandhi (1869–1948) Leaders have an essential role in facilitating strategic change within organizations. As resistance to change is primarily an emotional reaction to change, the study of emotions and the emotional intelligence of the leader is of growing interest in modern organizations. From a strategic perspective, the process of how the emotional intelligence of a leader contributes to competitive advantage for an organization is unclear. Based on the resource-based view of the firm, this paper introduces a framework that links emotional intelligence to competitive advantage. Essentially, it is argued that emotional intelligence leads indirectly to competitive advantage by influencing the leadership capability necessary for implementing effective strategic change. In the current volatile business environment, it is argued that organizations possessing emotionally intelligent leaders will be more likely to obtain competitive advantage. Suggestions for organizations are discussed and directions for future research are also presented. 2013-02-15T05:40:09.608Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:23921 Thesis (PhD)--Macquarie University, Macquarie Graduate School of Management, 2004. 2013-01-25T04:00:12.946Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:23191 'In Their Own Image: Greek-Australians' National Project was established 20 years ago by photographer Effy Alexakis, and historian Leonard Janiszewski. We are researching and documenting the Greek-Australian historical and contemporary presence both nationally and internationally - books, research articles, multimedia displays, successful international touring exhibitions and a documentary for television, have resulted. In 2001, the project became an associate of the Australian History Museum at Macquarie University. We provide lectures, photographic exhibitions and workshops both within the University and as an outreach activity, as well as maintaining our on-going research. That the Australian History Museum has incorporated our project within the University is both unique and significant. Projects dealing with ethnic groups have tended to be marginalized, but our current situation facilitates the mainstreaming of such research and recognition of the cultural and ethnic diversity and hybridity of Australia's past. The project acts as a conduit between the Museum, the University and Greek-Australians, and then engages the broader community through the activities arising from the research relationship. Our current research project - "American Beauties" at the Niagara Café - which will result in the production of a major book and touring exhibition, provides an excellent example of this process and how such a relationship can successfully provide previously untapped documentation and material to university museums and collections. 2012-12-03T09:20:32.699Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:22889 Book review of 'Les inscriptions coptes et grecques du temple d’Hathor à Deir al-Médîna suivies de la publication des notes manuscrites de François Daumas (1946-1947)', by Chantal Heurtel, Cairo : Institut francais d'archeologie orientale, 2004. 2012-11-25T22:41:31.759Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:22948 Type-II Hybrid-ARQ (Type-II HARQ) has been shown, under certain circumstances, to increase the efficiency and reduce loss of data transmissions over a wireless channel.

This paper investigates the optimal hop size and transmission strategy in networks with overlaid base stations. The objective is to maximize the minimum throughput any user achieves, excluding traffic that it relays. The optimum depends on the routing algorithm used, and a specific receiver-based algorithm is proposed. Optimal parameters are derived using a simplified model, and are shown by simulation to out-perform systems with the optimal position-invariant hop size. For this choice of objective, improvement is obtained by using one hop size for the base station and another for relays. 2012-11-21T09:22:08.042Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:22925 We consider the problem of multiuser detection in cellular networks. In particular, we present a distributed forward-backward algorithm with local message passing for efficient implementation of the Linear Minimum Mean Square Error (LMMSE) receiver, for a simple model of a one-dimensional cellular system. The distributed algorithm is based on the well-known interpretation of Kalman smoothing as a linear combination of the forward and backward filtered estimates. We also show that near-optimal performance can be achieved by only relying on information from a local linear segment of the entire array. This results in a limited extent distributed algorithm that greatly reduces processing delay, especially for large networks, yet with little loss in performance. 2012-11-21T09:22:00.754Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:22933 We derive the Linear Minimum Mean Square Error (LMMSE) receiver for Wyner's model of a linear cellular array. By exploiting the special structure of the channel model, we obtain explicit Mean Square Error (MSE) expressions and information capacity formulae for both finite-sized as well as infinite-sized linear cellular arrays. We show that the performance of an individual user becomes insensitive to the array size for large array sizes and that the proportion of users achieving almost the same performance converges to one, as the array size tends to infinity. The effects of intercell interference and noise on the performance of each user are also investigated. 2012-11-21T09:21:38.781Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:22777 "June, 2003" 2012-11-11T22:22:58.857Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:22650 17 page(s) 2012-11-05T02:21:09.027Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:22589 6 page(s) 2012-11-01T19:41:01.369Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:22598 Book review of 'The Changing Politics of Foreign Policy', by Christopher Hill, (Houndmills: Palgrave, 2003), ISBN:0333754239. 2012-11-01T19:40:46.709Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:22607 1 page(s) 2012-11-01T19:40:22.985Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:22612 1 page(s) 2012-11-01T19:40:19.124Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:22519 The change in linear attenuation coefficient with absorbed dose has been investigated for aqueous polyacrylamide, gelatine and tetrakis (PAGAT) and aqueous methacrylic acid, gelatine and tetrakis (MAGAT) normoxic polymer gel dosimeters using tetrakis (hydroxy methyl) phosphonium chloride as the antioxidant. The measured linear attenuation coefficient increased linearly with absorbed dose up to 15 Gy for PAGAT gels and 10 Gy for MAGAT gels. Computerized tomography (CT) numbers or Hounsfield units (H) were calculated from the linear attenuation coefficients and compared with values obtained using a CT scanner. Both calculated and measured CT numbers followed a similar pattern when fitted with a biexponential curve. The CT numbers obtained from linear attenuation measurements were found to be greater than that obtained with the CT scanner for both PAGAT and MAGAT polymer gels. The H-dose sensitivities of the MAGAT and PAGAT polymer gel dosimeters measured on a CT scanner were calculated to be (0.85 ± 0.08) H Gy⁻¹ and (0.31 ± 0.03) H Gy⁻¹, respectively.

The variation in magnetic resonance relaxation time (T₂) with absorbed dose was modelled assuming fast exchange of magnetization. Overall good agreement between the model and experimental data was obtained. However, comparison with FT-Raman data suggests that not all the protons attached to the polymer contribute to the relaxation process. Furthermore, for certain compositions improved agreement with experimental data was achieved when a lower fraction of polymer protons available for exchange with water was assumed in the low dose region. This indicates that the T₂ value is influenced by the composition and topology of the formed polymer, which may vary with absorbed dose. The concept of percentage dose resolution (DpΔ,%) was introduced to enable optimization of gel compositions for use in relative dosimetry applications. This concept was applied to demonstrate the effects of varying the gelatine concentration, the total fraction of monomer/crosslinker (%T) and the relative fraction of crosslinker (%C) on gel performance in HEA gels as well as compare the performance of HEA and a standard polyacrylamide gel (PAG). The percentage dose resolution was improved for all HEA gels compared to the PAG dosimeter containing 3% acrylamide and 3% BIS. Increasing the total concentration of monomer was shown to have the largest single effect. In the range of doses of interest for clinical radiation therapy, DpΔ,% for the optimal HEA gel (4% HEA, 4% BIS) was lower than 2.3%, compared to 3.8% for the PAG dosimeter. 2012-11-01T00:12:07.940Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:22550 The roads are a microcosm of society.

To demonstrate this hypothesis, the article analyses the opinion, expressed by Huntington and shared by some intellectuals and politicians, that we are experiencing a clash of civilisations between the West and Islam. By contrast, I argue that Europe perceives Islam as a transruptive (Hesse 2000) force that, through transculturation processes, might be able to challenge the alleged Judaeo‐Christian heritage of Europe. Islamophobia stems from the defence and resistance against the possible effects of real multicultural contacts between Islamic values and European–Western ones. 2012-06-18T09:46:28.898Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:19851 This paper describes the difficulties that Muslims in Northern Ireland have experienced in establishing an Islamic environment. Northern Ireland has a long tradition of religious and political conflicts between its Catholic and Protestant communities. The nature of these political events in the region, and the history of the local Muslim community, have had implications on the establishment of Islamic spaces and the ways in which Muslims organize their religious lives. However, at the risk of endangering relationships with the Protestant community, Muslims still feel the need to build a formal mosque. 2012-06-14T08:00:08.827Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:19475 To be in relative poverty is to be excluded from the normal activities and acceptable standard of living in one’s community. In order to determine whether poverty in Australia is due to involuntary or voluntary causes a detailed examination is undertaken of the causes of disadvantage and the groups on whom these causes are impacting. Poverty is defined as involuntary when it is caused by factors outside of individual control, or where choices are so limited that one cannot escape from poverty. Nationwide evidence and a case study of poverty in the Newcastle region suggest the following indicators of involuntary poverty: Structural unemployment, Excess of job seekers over job vacancies, Polarisation of job growth into high skilled and low-paid low-skilled work, Decline in social expenditure, Lack of access to affordable childcare services, Increased cost of further education, Mismatch of education with areas of job growth, Unequal access to the internet, Inadequate provision of public transport, Relatively low expenditure on health of low-income groups, Decline in bulk billing, Decline in availability of low cost housing, Below poverty line welfare payments, High effective marginal tax rates for welfare recipients entering paid employment. Secondary indicators produced by the above causes include the presence of cohorts of poverty and locations of disadvantage (postcodes of poverty). A statistical analysis of poverty in Newcastle shows that the variance in the log of odds of poverty between Newcastle’s suburbs is largely due to variations in cohorts of disadvantage and structural causes. This supports the hypothesis that the majority of poverty in Australia is involuntary. It is necessary that the government acknowledge that poverty is largely involuntary so that Australia can shift from a culture of blame to one of mutual responsibility. Government and community action is required to rectify the causes of involuntary poverty. This can be achieved through job creation schemes, sufficient compensation for the unemployed and other groups of disadvantage, adequate and affordable provision of infrastructure and services, such as public transport, childcare, health care, public housing and education. The result will be a more cohesive society with equal opportunity for all citizens and improved social and individual welfare. 2012-05-30T09:53:00.280Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:19120 Objectives: To review the strategies employed by overseas cigarette manufacturers operating in Thailand to obstruct the passage and subsequent enforcement of national public health legislation, specifically the ingredients disclosure provision of the 1992 Tobacco Products Control Act. Methods: Analysis of previously confidential tobacco industry documents relevant to non-compliance with the ingredients disclosure legislation. Results: Requirement for disclosure of ingredients contained in cigarettes contained in the Tobacco Products Control Act was identified by transnational tobacco companies (TTCs) not only as a significant threat to their operations in Thailand, but as a dangerous global precedent. Industry documents reveal a determined campaign to block, stall, or amend the proposed regulation during the legislative process. Industry representatives petitioned the Ministry of Health to revise the requirement from by brand disclosure to a more palatable by company submission. Strategies were adapted in the wake of the passage of the Act. Most significantly, the industry in concert with embassies in Bangkok threatened the Thai government with appeals to international trade bodies on the grounds of violation of international agreements. Industry documents also reveal that as submission of ingredient lists appeared unavoidable, leading companies operating in Thailand endeavoured to confound the disclosure requirement by disguising ingredients and reformulating brand recipes. Conclusions: The evidence presented highlights the importance of ingredients regulation and demonstrates how health policy can be transformed during its implementation. A greater understanding of trade agreements emerges as a priority for global tobacco control. 2012-05-10T09:50:28.760Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:19121 Objectives: To examine British American Tobacco’s (BAT’s) renewed interest in Cambodia from the early 1990s, reviewing negotiations to establish a joint venture and the subsequent conduct of BAT Cambodia (BATC). Methods: Analysis of previously confidential BAT documents relevant to the Cambodian market. Results: With the advent of comparative political stability in the early 1990s, BAT was quick to explore the possibilities for investment. The Cambodian government urgently required foreign investment, offering inducements and assistance to investors. In developing a joint venture, BAT saw a cost effective opportunity to dominate the local market and to defend its regional interests, Cambodia being viewed as strategically located to support smuggling. Given minimal advertising regulation, BATC have undertaken wide ranging promotions and sought to prevent advances in tobacco control. Conclusions: BATC is presented as a contribution to Cambodia’s regeneration, but the documents highlight its exploitation of state incapacity and an escalating threat to public health. 2012-05-10T09:50:21.695Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:19122 Objectives: To examine the complicity of British American Tobacco (BAT) in cigarette smuggling in Asia, and to assess the centrality of illicit trade to regional corporate strategy. Methods: Analysis of previously confidential documents from BAT’s Guildford depository. An iterative strategy combined searches based on geography, organisational structure, and key personnel, while corporate euphemisms for contraband were identified by triangulation. Results: BAT documents demonstrate the strategic importance of smuggling across global, regional, national, and local levels. Particularly important in Asia, contraband enabled access to closed markets, created pressure for market opening, and was highly profitable. Documents demonstrate BAT’s detailed oversight of illicit trade, seeking to reconcile the conflicting demands of control and deniability. Conclusions: BAT documents demonstrate that smuggling has been driven by corporate objectives, indicate national measures by which the problem can be addressed, and highlight the importance of a coordinated global response via WHO’s Framework Convention on Tobacco Control. 2012-05-10T09:50:15.268Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:18910 The performance measures important to New Zealand beef producers and processors in their selling and buying decisions were studied using a conjoint analysis methodology. 98 producers and 5 processors were asked to rank and rate various scenarios.

A biological or biologically derived recognition component can then be linked to the SAM in fabricating a biosensor. This time consuming immobilisation step can be a drawback in biosensor development, especially when repeated preparations of the biosensor are required. In this work, an alternative immobilisation strategy involving the direct application of a known quantity of the ethanolic solution of the alkanethiol, thioctic acid, on a gold electrode surface was studied. The solution was left to dry at room temperature for approximately 20 min. Comparable results including the relative percentage decrease in double layer capacitance, the surface coverage and the percentage of binding to the bacterial protein, Protein A, were obtained relative to those obtained with SAM formed by the immersion method. Shewhart’s statistical analysis technique was applied to examine the stability in terms of the relative percentage decrease in double layer capacitance. In these tests, within 99.7% confidence control limits, only a 1% deterioration was observed over a 3-month period. Therefore, all these results have demonstrated that the direct application method yields a stable thioctic acid SAM on a gold electrode surface with characteristics similar to those obtained with an immersion method. However, formation of a SAM using direct application can be achieved within a significantly shorter period of time compared to immersion method. 2012-02-22T22:00:05.304Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:17423 32 page(s) 2012-02-07T09:41:53.477Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:17417 24 pages(s) 2012-02-07T00:40:06.516Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:17089 Labour management policy currently reflects a more concerted effort by scholars to place fender at the foreground of equitable work practices. 2012-01-20T14:31:10.149Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:16917 Previous research has investigated the determinants and consequences of customer loyalty, but in banking, a critical but often neglected measure is the customer’s ‘share of wallet’ (SOW). Since some customers are more active in either investments or loans, the study, based on a survey of 1,924 retail banking customers, models SOW separately in terms of deposits and debts/loans. The results suggest that approximately 25% of the variance in share of wallet can be predicted, in particular by demographic factors such as age, income and a customer’s location. The typical client with growth potential for deposits is found to be male, aged 35-65, has a high income and a university degree, and lives in a city area. In contrast, factors such as satisfaction, attitude and service quality were not significant predictors of SOW. Implications for bankers and researchers are discussed. 2012-01-16T06:13:09.754Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:16800 3 pages(s) 2012-01-11T10:42:20.758Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:16839 There is a worldwide effort to identify international best practice in retirement income provision.

This paper seeks to compile disparate pieces of advice, distilled from recent research, which economists can usefully pass onto superannuation members, managers, trustees and policymakers. No prior knowledge of superannuation is assumed. Various policy issues are addressed, including the inadequacy of Australia's mandatory 9% contribution rate, the efficiency and equity costs of our unusual "front-end" superannuation taxes, and the tension in regulatory policy between protecting inactive or ill-informed contributors and giving well-informed contributors the right to back their personal judgements. 2012-01-11T10:40:10.329Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:13102 10 page(s) 2011-12-07T01:01:12.519Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:15928 6 page(s) 2011-11-14T19:40:38.431Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:1676 We report efficient operation of a KGd(WO4)2 Raman laser pumped by a small, 1 W, 532 nm laser module.

An example of such a system is a fullerene molecule between two metal electrodes. The description is based on a quantum master equation for the density operator of the electronic and vibrational degrees of freedom and thus incorporates the dynamics of both diagonal (population) and off diagonal (coherence) terms. We derive coupled equations of motion for the electron occupation number of the dot and the vibrational degrees of freedom, including damping of the vibration and thermo-mechanical noise, and give a semiclassical description of the dynamics under a variety of bias conditions. This dynamical description is related to observable features of the system including the stationary conductance as a function of bias voltage. 2011-10-31T13:49:49.404Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:15690 215 page(s) 2011-10-28T10:44:56.001Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:7422 2011-10-28T02:40:27.434Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:15645 This paper uses Systemic Functional Linguistic (SFL) theory as a basis for extracting semantic features of documents.

The Bayesian approach provides risk traders with the flexibility of adjusting their VaR models according to their subjective views. First, we deal with the case of linear portfolios. By imposing the conjugate-prior assumptions, a closed-form expression for the Bayesian VaR is obtained. The Bayesian VaR model can also be adjusted in order to deal with the ageing effect of the past data. By adopting Gerber-Shiu's option-pricing model, our Bayesian VaR model can also be applied to deal with non-linear portfolios of derivatives. We obtain an exact formula for the Bayesian VaR in the case of a single European call option. We adopt the method of back-testing to compare the non-adjusted and adjusted Bayesian VaR models with their corresponding classical counterparts in both linear and non-linear cases. 2011-10-05T13:10:48.940Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:15238 Credit risk measurement and management are important and current issues in the modern finance world from both the theoretical and practical perspectives. There are two major schools of thought for credit risk analysis, namely the structural models based on the asset value model originally proposed by Merton and the intensity‐based reduced form models. One of the popular credit risk models used in practice is the Binomial Expansion Technique (BET) introduced by Moody's. However, its one‐period static nature and the independence assumption for credit entities' defaults are two shortcomings for the use of BET in practical situations. Davis and Lo provided elegant ways to ease the two shortcomings of BET with their default infection and dynamic continuous‐time intensity‐based approaches. This paper first proposes a discrete‐time dynamic extension to the BET in order to incorporate the time‐dependent and time‐varying behaviour of default probabilities for measuring the risk of a credit risky portfolio. In reality, the ‘true’ default probabilities are unobservable to credit analysts and traders. Here, the uncertainties of ‘true’ default probabilities are incorporated in the context of a dynamic Bayesian paradigm. Numerical studies of the proposed model are provided. 2011-10-05T13:10:44.309Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:15240 15 page(s) 2011-10-05T13:10:43.216Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:14959 Since the inception of the General Agreement on Tariffs and Trade (GATT) in 1947, later to be expanded as the World Trade Organisation (WTO), much has been done to improve free trade.

We show that liberalizing the quantity control could reduce investment in the industry under certain circumstances. Furthermore, the level of investment in the industry is different depending on whether the licenses are tradable or not. Key factors to consider are the elasticity of demand for the final good and the degree of input substitutability.

Eels were challenged in the presence of a physiological and physical stress akin to that preceding the winter outbreaks of saprolegniosis in farms. The concentration of Saprolegnia parasitica cysts was 9±1.2 cysts/ml for the initial challenge. Morbidity due to saprolegniosis was low, at 27% in A199-treated tanks, in comparison to the 44% recorded for the non-treated control tanks. The subsequent addition of live A199 cultures to the treatment tanks resulted in the recovery of fish suffering from saprolegniosis (p=0.038), with temperature appearing to be a factor regulating the effect of A199. It was concluded that A199 is a potential agent for the management of winter outbreaks of saprolegniosis in eels. 2011-08-17T23:00:11.322Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:14567 The potential of Aeromonas media strain UTS A199 as a candidate for the biocontrol of winter saprolegniosis was tested during a winter outbreak in a farm and in a laboratory challenge trial on silver perch, Bidyanus bidyanus Mitchell. The daily addition of A199 to tanks during the winter outbreak of saprolegniosis resulted in a significant increase (p<0.05) in fish survival. Close monitoring of fish revealed that A199 treatments halted the progress of the disease by inhibition of hyphal growth within lesions and cyst germination. In a laboratory-based challenge of perch by exposure to high numbers of cysts and zoospores of Saprolegnia parasitica, the presence of A199 in the tank water delayed the onset of the disease but, ultimately, could not protect the fish from the disease under these conditions. 2011-08-17T23:00:08.107Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:14416 We predicted that biofilm would form on surfaces of endoscope tubing in contact with fluids, and may be difficult to remove by current washing procedures. Its presence may protect micro-organisms from disinfectant action and contribute to failure of decontamination prior to re-use. Tubing samples removed from 13 endoscopes that had been sent to an endoscope-servicing centre were examined for the presence of biofilm and bacteria by scanning electron microscopy. Biological deposits were present on all samples tested. Biofilm (bacteria plus exopolysaccharides matrix) was present on the suction/biopsy channels of five of 13 instruments, and was very extensive on one of these. Bacteria and microcolonies were often but not necessarily associated with surface defects on the tubing. All 12 air/water channels examined showed biofilm, and this was extensive on nine samples. Routine cleaning procedures do not remove biofilm reliably from endoscope channels, and this may explain the unexpected failure of decontamination encountered in practice despite good adherence to infection control guidelines. 2011-08-09T12:02:41.660Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:14415 Background: Biofilm consisting of bacteria enclosed in a matrix of exopolysaccharide (EPS) forms on many medical devices such as catheters and implants. Nosocomial infection is, thus, a newly recognized scenario of biofilm development. Biofilm removal by physical methods such as ultrasound and mechanical cleaning is reasonably effective but difficult to supervise in practice. Chemical methods are often ineffective because of biofilm resistance to biocides. In this study, we compared the efficiency of different detergents used in endoscope reprocessing. Methods: Escherichia coli biofilm was generated on Teflon and medical grade PVC tubing under low flow conditions. Sections of biofilm covered tubing were washed using test detergents and biofilm removal was assessed by counting remaining adherent bacteria after washing and by scanning electron microscopy to qualitatively assess the amount and nature of the remaining biofilm. Results: Control tubing developed a multilayered biofilm consisting of >105 bacterial cells/cm2. Only Matrix (Whiteley Medical, Sydney, Australia) produced >4 log reduction in viable bacterial numbers. Matrix and Epizyme Rapid (3M Australia, Pymble, Australia) were able to remove up to 75% and 60% of the biofilm, respectively. Conclusions: Many commonly used enzymatic cleaners fail to reduce the viable bacterial load or remove the bacterial EPS. Cleaners with high enzyme activity, Epizyme Rapid, removed more biofilm but failed to reduce bacterial numbers more than 2 logs. The only cleaner containing no enzymes, Matrix, significantly reduced bacterial viability and residual bacterial EPS. 2011-08-09T12:02:37.820Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:14419 98 pages(s) 2011-08-09T12:02:17.795Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:14421 3 page(s) 2011-08-09T12:02:03.023Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:14336 A case of recurrent Miller–Fisher syndrome is presented and features of this very rare condition are discussed. 2011-08-06T02:41:35.437Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:14129 10 page(s) 2011-08-01T06:27:37.113Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:14144 University-industry partnerships (UIPs) are widely viewed as essential in leveraging research capability and economic performance in organizations and the nation as a whole.

The X-ray diffraction (XRD), infrared spectra (IR), thermo gravimetric analysis (TGA) and scanning electron microscope (SEM) investigations showed that the two materials had different phase compositions, water content and particle sizes. The cells with BGM had a higher open circuit voltage (OCV) and discharged at higher voltages as compared to those with EMD. The discharge capacity of BGM was lower compared to that of EMD. On discharge both the materials produced same phase i.e. lithium intercalated manganese dioxide (LixMnO₂). This was also confirmed through X-ray photoelectron spectroscopy (XPS) investigation of the discharged products. 2011-06-29T06:20:55.101Z ]]>
