Work-ready wiki: Supporting the learning and teaching of professional graduate attributes

The paper presents the background, design and formative evaluation of a wiki of workready learning activities and teaching support resources to improve the learning of professional graduate attributes. The 'Improving graduate work-readiness' project is a University of Technology Sydney curriculum renewal project involving five Faculties. The project aims to improve graduates' professional attributes and employability skills by designing new subjects, new subject modules and integrating short well-designed contextualised work-ready learning activities into existing subjects. The authors inquired of relevant professional societies their understandings of the key professional attributes required of a graduate in the contemporary workplace. These findings informed the design of a matrix of 11 professional attributes and associated sub-attributes and aligned understandings and skills that can be learnt. The work-ready wiki gives access to a matrix of generic work-ready learning activities and 16 matrixes of learning activities contextualised for each professional area of study involved in the project to-date. Workready activities contextualised for each profession maximises student relevance and motivation to learn. Maximising the ease of integration of work-ready activities into existing subjects has guided the design of the wiki-based learning activities. From the wiki practical teaching support resources can be downloaded to enable easier integration of the work-ready learning activities. The beginning of collections of work-ready learning activities can be found at . © 2008 Andrew Litchfield and Skye Nettleton

Test of Information Theory on the Boltzmann Equation

We examine information theory using the steady-state Boltzmann equation. In a nonequilibrium steady-state system under steady heat conduction, the thermodynamic quantities from information theory are calculated and compared with those from the steady-state Boltzmann equation. We have found that information theory is inconsistent with the steady-state Boltzmann equation.Comment: 12 page

Classification of Message Spreading in a Heterogeneous Social Network

Nowadays, social networks such as Twitter, Facebook and LinkedIn become increasingly popular. In fact, they introduced new habits, new ways of communication and they collect every day several information that have different sources. Most existing research works fo-cus on the analysis of homogeneous social networks, i.e. we have a single type of node and link in the network. However, in the real world, social networks offer several types of nodes and links. Hence, with a view to preserve as much information as possible, it is important to consider so-cial networks as heterogeneous and uncertain. The goal of our paper is to classify the social message based on its spreading in the network and the theory of belief functions. The proposed classifier interprets the spread of messages on the network, crossed paths and types of links. We tested our classifier on a real word network that we collected from Twitter, and our experiments show the performance of our belief classifier

ISSFAL 2010 dinner debate: healthy fats for healthy hearts - annotated report of a scientific discussion

&lt;i&gt;Background/Aims:&lt;/i&gt; The importance of reducing saturated fatty acid intake to prevent cardiovascular disease and recommended intakes for omega-6 polyunsaturated fatty acids (PUFAs) are controversial. Therefore, experts debated these topics at the biennial meeting of the International Society for the Study of Fatty Acids and Lipids (ISSFAL), in May 2010. &lt;i&gt;Methods:&lt;/i&gt; Debate transcripts, debaters’ and discussants’ reviews and literature citations were the basis of this report. &lt;i&gt;Results:&lt;/i&gt;Participants agreed that saturates per se are not ‘bad’, but that dietary recommendations should emphasize the substitution of unsaturates for part of the saturates. Evidence supporting omega-6 PUFA intakes of 5 to 10% is mixed; some interpret the overall data from diverse studies as consistent with a reduction in the risk of cardiovascular mortality and events. Others assert that randomized controlled trial data suggest that higher intakes of omega-6 PUFAs are not associated with lower risk of heart disease, or may even increase it. &lt;i&gt;Conclusions:&lt;/i&gt; All agreed that a 5-year randomized controlled trial comparing the effects of historically low (2%) with currently high (7.5%) linoleic acid intakes on cardiac endpoints would address the knowledge gap about the effects of different omega-6 PUFA intakes on the risk of heart disease.</jats:p

Dietary fatty acids: is it time to change the recommendations

Limiting the saturated fatty acid (SAFA) consumption forms the basis of dietary fat recommendations for heart health, despite several meta-analyses demonstrating no link be- tween dietary SAFA and the risk of cardiovascular disease (CVD). Three experts on dietary fat and health discussed the evidence of reducing SAFA intake at a symposium of the Federation of European Nutrition Societies in Berlin, Germany, October 23, 2015. Ronald P. Mensink, Maastricht University, the Netherlands, discussed the evidence linking dietary fatty acids and CVD risk. He emphasized the impor- tance of the replacement nutrient(s) when SAFA intake is re- duced. Julie Lovegrove, University of Reading, UK, addressed the question of whether higher intakes of unsaturated fatty acids are beneficial. She discussed the replacement of SAFA by polyunsaturated fatty acids (PUFA) and monounsaturat- ed fatty acids (MUFA), noting the reduction in CVD risk with PUFA replacement and in CVD risk markers with MUFA re- placement of SAFA. Ursula Schwab, University of Eastern Finland, Kuopio, Finland, discussed the importance of di- etary patterns in achieving reduced risk of CVD, observing that several dietary patterns following the principles of a health-promoting diet and adapted to local customs, food preferences and seasonality are effective in reducing the risk of CVD, type 2 diabetes and other chronic diseases. This pa- per summarizes the symposium presentations

Some thoughts about nonequilibrium temperature

The main objective of this paper is to show that, within the present framework of the kinetic theoretical approach to irreversible thermodynamics, there is no evidence that provides a basis to modify the ordinary Fourier equation relating the heat flux in a non-equilibrium steady state to the gradient of the local equilibrium temperature. This fact is supported, among other arguments, through the kinetic foundations of generalized hydrodynamics. Some attempts have been recently proposed asserting that, in the presence of non-linearities of the state variables, such a temperature should be replaced by the non-equilibrium temperature as defined in Extended Irreversible Thermodynamics. In the approximations used for such a temperature there is so far no evidence that sustains this proposal.Comment: 13 pages, TeX, no figures, to appear in Mol. Phy

Shock tunnel studies of scramjet phenomena, supplement 6

Reports by the staff of the University of Queensland on various research studies related to the advancement of scramjet technology are presented. These reports document the tests conducted in the reflected shock tunnel T4 and supporting research facilities that have been used to study the injection, mixing, and combustion of hydrogen fuel in generic scramjets at flow conditions typical of hypersonic flight. In addition, topics include the development of instrumentation and measurement technology, such as combustor wall shear and stream composition in pulse facilities, and numerical studies and analyses of the scramjet combustor process and the test facility operation
