Sometimes it is also accepted that the author simply provides constructive critical analysis of existing theories or viewpoints without necessarily offering any new ones. In short academic requirements for a thesis, especially the demand of originality, are much higher than for a research paper. Each university sets its own rules and regulations for presentation style and the length of a thesis depending on the research area. In some universities the rules can be stricter, foreseeing very specific style and format requirements. There are however certain components that are always prerequisite in thesis presentation style, such as table of contents or abstract. You may include a dedication or acknowledgement and depending on the research field, graphics, tables or research methods. All the aforementioned components might not be expected in a research paper. However, as both are academic documents bibliography together with accurate referencing must be presented.
The before-and-after comparison itself is not a thesis; the thesis is the identification of the intervening event or events that produced the difference. Cohen explains the mobilization of workers by pointing to changes in their daily lives in the 1920s and early 1930s. Evidence for that thesis comprises the rest of her book. Mattheisen suggests that the difference between the two television series can be attributed to events of the Cold War. In the early 1950s, at the start of the Cold War, war against totalitarianism seemed simple. Twenty years later, the ambiguity of the Vietnam War inspired an ambiguous account of World War II.
