(Dressler, 2010, paraphrased) Emulation is held in the work of Oltmans and Kol to be "more cost-effective for preserving large collections, despite the relatively high initial cots for developing an emulation device." (Dressler, 2010, p.1) Emulation is contrasted to migration in that migration is applicable to all the objects in a collection respectively, creating high ongoing costs" whereas emulation chaining for the future is likely to detract from this. Emulation can be implemented "at a higher level than the migration approach" therefore, instead of the development of conversion solutions per format "institutions can develop emulation solutions per environment." (Dressler, 2010, p.1) Emulation has not been used widely in preserving over the long-term and there is a need for tests of practicality prior to conclusions being made about the reliability of emulation. Additionally, as noted by Dressler (2010) the selection of emulation strategy ultimately requires "buying into a migration strategy because emulators themselves become obsolete" making the replacement of the old emulator with a new emulator a requirement or alternatively requiring that a new emulator be created. The work of Rothenberg reports that migration is: (1) labor intensive; (2) time-consuming; (3) expensive; (4) error-prone; (5) risky; and (6) non-scalable and as well that migration makes a requirement of new solution for every new format. (in: Granger, 2000, p.1) Granger (2000) states of migration that it "has been the only serious candidate thus far for preservation of large scale archives" and that not all of these will be valid "with equal force all of the time, with migration many of these claims will vary on a case-by-case basis. Moreover, one has to ask, 'Labor intensive, expensive, etc.,' compared with what?" (Granger, 2000, p.1) Granger states that the ideal approach would be one offering alternatives "for levels of safety and quality, volume of storage, ease of access, and other attributes at varying cots, and it should allow these alternatives to be changed for a given document, type of document, or corpus at any time in the future." ( ) in addition access to all documents should involve only one step...
Migration in the UK Evaluate claim migration positively valued UK-essay Sources:Chapter 4 main source information material Chapter 5 Exploring Social Lives, Milton Keynes, Tne Open University. Illustrate support arguments.. Migration is the process by which humans move physically from one location to another, in order to stay there permanently or semi-permanently. There is voluntary migration where an individual moves at their own will within their own region, country or overseas. Involuntary migration
However, eventually people stopped paying much attention to the color of the threat level for that day, and the news media stopped talking about it. Now, it is not discussed at all. Was it effective? Perhaps as a short-term measure, but certainly not as a long-term solution. The government argues that the American people are much safer today, because there have been no more terrorist attacks. However, correlation does
According to Schiller this unequal regulation of migration may have a great deal to do with the strength or weakness of transnational networks. The author explains that in most cases people have strong bonds to their homeland and send a portion of their wages back to relatives that are still in their home countries. In addition immigrants from certain countries in Europe such as Italy have strong support systems
Migration - UK The history of humanity is also the history of migration, according to professor Harzig and colleagues. The original Homo sapiens migrated out of East Africa and spread slowly across the world (Harzig, 2009, 8). Essentially, migration is the cross-border activity that individuals carry out in order to relocate for a number of potential purposes. The five basic aspects of migration are as follows: a) migration "within a cultural
Migration Habits of Humans Migration is as common a biological factor as exists in the world. Birds are known to migrate over thousands of miles, sometimes even over open ocean, to get back to prime nesting sites. Possibly the longest migration occurs when the leatherback sea turtle migrates from the southern coasts of South America to the frigid northern waters of the Asian Bering Strait. These biological migrations occur yearly, but
Migration in the UK is something that has many different meanings and that has been addressed in a number of different ways throughout the years. The question here is whether migration is valued by people in the UK, or whether there is a problem with people who are considered to be migrants. Often, the feelings about migrants in the UK depend on the way they understand the term (Bromley, et
