Population and the Property in Australia - Essay Example The students were presented with a set of propositions expressing different views of the war in Iraq and asked to select the response which best reflected their own views. Over 70% agreed either with the proposition that "Australia should never have been involved in the US-led war in Iraq" or "Australia should no longer be involved in the US-led war in Iraq". This contrasts with surveys of young Australians conducted in early 2004, which showed a much higher level of support for Australian involvement in the war. Sample here is the student community whose views are being collected. The population is depicted as the overall population of Australia. Property is the personal views of Australians regarding the govt involvement in War in Iraq. An argument can be evaluated on the basis of certain factors. First of all, the sample case of students being extended to total population is not totally adequate because of the age factor. Students of a university who are not experienced in international affairs and the government working are presenting their personal views which are themselves based on what their peers think. This age factor cannot be extended on to the overall population as there are middle-aged men and women and the older generations who are more mature and experienced. The research methods used are also not considering the viewpoint of people other than young students. Conclusion about the evaluation is deduced as not justified because the views of people more experienced and strong vie w point is not considered. In causal research, why is it important for test group and control group to be similar? What method of test group/ control group selection is most likely to result in the test group and control group being similar? Why? Explain, using an example, why it is not always appropriate to use that more reliable form of test group/control group selection.

Operations Management - Assignment Example These two early industrial revolutions have made people extremely rich and able to embrace urbanization. Now, the third revolution is underway, and this is represented by the digitalization of manufacturing. It is a fact that this digitalization of manufacturing is likely to transform business and much more. Several outstanding technologies are converging: novel materials, new processes such as 3D printing, clever software, as well as wide range of internet-based services (Markillie 2012). Factories that operated in the past majored in making identical products. For instance, Ford asserted that all those individuals who were interested in purchasing cars had the option of having any color they preferred, so long as it was closely related to black. It is also imperative to understand the fact that the production cost of small batches of varied products that are tailored to customer’s demands, is falling. This implies that the future factories will emphasize on mass customizatio n, and may appear similar to the weavers’ cottages of the 18th century and not Ford’s assembly line. The old fashioned way of making things entailed welding or screwing of several parts of a machine together. However, in the recent times, a product can be designed easily on a computer and the printed with the help of a three-dimensional printer. The three-dimensional printer helps in the creation of solid objects by building up sequential layers of material. This digital design can also be tweaked in order to make it better just by a few mouse-clicks (Stevenson 2011). Since the 3D printer is electronic, it can run on its own without a worker attending to it. Additionally, it can make several complex things which cannot be handled by a traditional factory. With time, it is argued that these 3D printers will be able to make anything from anywhere. For instance, you can give it a command from any part of the world and let it do the printing work. This digitalization is bo und to promote mechanization to unmeasured heights. The three-dimensional printing applications are extremely mind-boggling. High technology parts of military jets and hearing aids are already in customized shapes. Therefore, with the continued improvement of the technology, there is likely to be a change in the geographic supply chain. For instance, an engineer conducting his work in a deserted area, who lacks any engineering tool does not necessarily have to make arrangements for the tool to be delivered to him from the nearest town. What he can do is to download the tool’s design and print. From this development, it is correct to say that days when projects used to be halted since some parts of the construction kit were unavailable, or customers raising complaints for not finding spare parts for items bought are soon becoming quaint. Other transformations are also momentous. For instance, the novel materials used in the factories are light, strong and durable compared to t he old ones. Aluminium and steel products are being replaced by carbon fibre in products such as mountain bikes and airplanes. New technologies have enabled engineers to shape objects and make tiny adjustments. On the other hand, nanotechnology is promoting products by giving them enhanced features. For instance, it promotes the creation of crockery that facilitate easy cleaning, bandages that are capable of healing cuts, engines that efficiently run, just to mention but a
