...2010 Fourth International Conference on Network and System Security Security-oriented Workflows for the Social Sciences Prof. Richard O. Sinnott, University of Melbourne, Melbourne, Victoria, 3010, Australia, rsinnott@unimelb.edu.au Sardar Hussain National e-Science Centre University of Glasgow, Glasgow G122 8QQ, Scotland s.hussain@nesc.gla.ac.uk Abstract — The service-oriented computing paradigm and its application to support e-Infrastructures offers, at least in principle, the opportunity to realise platforms for multi- and inter-disciplinary research. Augmenting the service-oriented model for e-Research are mechanisms for services to be coupled and enacted in a coordinated manner through workflow environments. Typically workflows capture a research process that can be shared and repeated by others. However, existing models of workflow definition and enactment assume that services are directly available and can be accessed and invoked by arbitrary users or enactment engines. In more security-oriented domains, such assumptions rarely hold true. Rather in many domains, service providers demand to be autonomous and define and enforce their own service / resource access control using locally defined policy enforcement points (PEP) and policy decision points (PDP) which allow access and usage of resources to be strictly monitored and enforced. In this paper, we outline how it is possible to support security-oriented workflow definition and enactment through chaining...

...Midland's cost of capital 1. I choose the rate of 30-year U.S. Treasury bonds in 2007 (4.98%) as the risk free rate in the 2007 WACC calculations. The reason is that majority of large firms and financial analysts report using long-term yields for bonds to determine the risk-free rate. Rf=0.0498 2. Cost of debt, which is determined by adding the spread to Treasury (1.62%) to the rate of 30-year treasury bonds in 2007. Rd=0.0498+0.0162=0.066 3. Cost of equity, the EMRP (5%) and D/E (59.3%) was taken out of the context of the case. βa=Equity Beta/(1+D/E)= 1.25/(1+0.593)= 0.78 According to Table1, consolidated D/V is 42.2%, E/V is 57.8%, βe= βa*(1+D/E)= 0.78*(1+0.422/0.578)=1.35 Re=Rf+ βe *EMRP= 0.0498+(1.35*0.05)= 0.1173 4. WACC, the tax rate (38.58%) was from the 2006 taxes paid. WACC= D/V*(1-T)*Rd+E/V*Re= 0.422*(1-0.3858)*0.066+0.578*0.1173=8.49% The division costs of capital Exploration & Production 1. I also use of 30-year U.S. Treasury bonds in 2007 (4.98%) as the risk free rate, Rf=0.0498. 2. Cost of debt, Rd=Rf+ the spread to Treasury(Exploration & Production)=0.0498+0.016=0.0658 3. Cost of equity, EMRP=5%. Since we can’t get the beta of E&P, we should use the information of comparable companies on Exhibit 5 to get average asset beta, and then to calculate the beta of E&P. βa=Equity Beta/(1+D/E)= 1.15/(1+0.398)= 0.82 According to Table1, consolidated D/V is 46%, E/V is 54%, βe= βa*(1+D/E)= 0.82*(1+0.46/0.54)=1.52 Re=Rf+...

...Pick Me: Slotting Product “Some have argued that slotting allowances – and a variant known as pay-to-stay fees, paid by manufacturers to keep existing products on retailers’ shelves – harm consumers by, among other things, excluding certain manufacturers and thereby impairing competition that otherwise would take place. Defenders of slotting allowances have asserted that, among other things, they cover the cost of introducing new products to the marketplace and thereby tend to foster entry and innovation”. (ftc.gov 2001) While the Department of Justice concludes that the practice of slotting allowance is not an antitrust issue there is a possibility that there may be issues in the future with anticompetitive exclusion. Slotting allowance is a practice used by manufacturers and retailer to stock certain products on the shelves. It was most prevalent in supermarkets but spread to other store i.e. electronic stores and computer stores. For example, Microsoft pays a fee to have an end cap (spot at the end of an aisle) to display their product only. Some feel that it is an exclusivity practice that leaves out smaller businesses that cannot compete with the fees required by retailers. The process was for manufactures to introduce new product to customers. But it is now a wide spread practice to charge a fee to keep their mature (older) products on the shelf. The practice allows for retailers to build their market power. Pros and cons of slotting allowances: 1) Pros ...

...Capstone Rehearsal Guidelines (Revised 9-27-14) Overview The Capstone Rehearsal is an individual simulation that enables students to compete against computer competitors as a means to sharpen their decision making skills and knowledge of the Capstone simulation. It should be noted that the Rehearsal simulation does not include the optional TQM module that is being used in this course. This is because instructors are not given the option to include TQM functions in the rehearsal simulation. Due to some recent updating of the user interface in the Capstone rehearsal the revised guidelines presented below are being made available. Please note, the way the user screens for the tutorial and rehearsal may appear slightly differently depending on whether you are using the legacy view or the Beta view of Capstone. You should be able to switch from one to the other by clicking a control at the very top of your screen. If you have any questions about switching from legacy to beta view or vice versa, please call Capsim Technical Support directly at 877-477-8787. User Operating Guidelines 1.

...WT AWT vs. Swing AWT vs. Swing For this assignment, it has been requested the author write a review of the advantages and disadvantages of AWT (Abstract Window Toolkit) vs. Swing in writing a Java program. AWT is a portable GUI library for standalone applications or applets with an advantage of speed in it’s use of native peers and performance. Additionally most web browsers support AWT so the applets designed will have greater ease in use and design and AWT components look similar to the operating system in which they run on. Swing uses a set of GUI components built upon AWT technology and gives it something of a “plug and play” feel and is implemented entirely in the Java programming language. Having pure Java design, it has a greater range of behavior and not limited by the native peers that AWT uses. Additionally it has a wider range of features like icons and pop up tools. Another thought, and this is opinion, is that Sun puts more interest into swing and makes it a more robust program for it’s web based uses. The look and feel with it’s pluggable abilities lets a user design a single set of GUI applications that look similar to the native OS it is running on. Some disadvantages of AWT are the third party development and it’s smaller set of components that are available and the components typically do not support icon and tool tips. With swing, the general overall performance is slower and buggier than AWT, as this author has learned firsthand in writing with both...
