Here is my sandbox for testing and previewing article content. Fortune favors the bold, after all. Italics aren't so lucky. As an exercise, I will summarize the guidelines of Wikipedia.
Introduction[edit]
Wikipedia is open to the public for editing but there are guidelines that must be followed to ensure order and acceptable content. There are five overarching guidelines for the editing process on Wikipedia:[1]
- Wikipedia is an online encyclopedia
- Wikipedia has a neutral point of view
- Wikipedia is free content
- Editors should interact with each other in a respectful and civil manner
- Wikipedia does not have firm rules
The five pillars of Wikipedia[edit]
Wikipedia is an online encyclopedia[edit]
Wikipedia follows the format of an encyclopedia or almanac. It should not be treated as a dictionary or repository of linked sources.
Wikipedia has a neutral point of view[edit]
Articles should be neutral in tone. Personal views and advocacy are not appropriate. Objective reporting is key. Information should be backed by outside sources.
Wikipedia is free content[edit]
Articles on Wikipedia are not copyrighted and any user can edit them. Copyright law must be respected. While short quotes from copyrighted material may be appropriate, free sources are preferable. Plagiarism is not tolerated. Quotes and summarizations must be cited.
Editors should interact with each other in a respectful and civil manner[edit]
Respect should be shown to fellow Wikipedia users. Conflict over editing is to be avoided. Feedback should be taken constructively.
Wikipedia does not have firm rules[edit]
The spirit of the law is of the most importance. Wikipedia is a fluid community with shifting ideas. Honest mistakes are surmountable.
Other guidelines[edit]
Verifiability[edit]
Using verified sources of information is of the utmost importance as this community is open.
Notability[edit]
Only notable topics should be covered. Some criteria to decide if a topic is notable include:
- significant coverage: the topic in question must be referred to directly and not in a trivial manner.
- reliable sources: at least two secondary sources from different authors or publishers.
- independent of the topic: advertising and self-published material does not count for these purposes.
No original research[edit]
Wikipedia is a source of tertiary information. Original research is not appropriate. Wikipedia deals with summaries of secondary sources of information.
Copyright and plagiarism[edit]
Only short, cited quotations are allowed. Large blocks of text from another source will be removed.
Characteristics of quality articles[edit]
Following are some concrete tips for writing high-quality articles on Wikipedia.[2]
- Quality articles should be well-written. Proper spelling, punctuation and grammar are important. It should stylistically match the community guidelines for formatting and organization.
- The article should be appropriately broad in scope. In-depth, advanced coverage should be avoided. In-line citations for statistics, direct quotes and controversial statements are expected.
- A good article is neutral in viewpoint. This is not the place for a soapbox.
- The article should contain no original research. It must be supported by outside material with listed references.
- Images, if relevant to the topic, are encouraged.
- It is expected that the article will remain relatively stable. Daily edits are discouraged.
Unit 5: Article summaries[edit]
Carcinogenesis is generally seen as a longterm process involving the accumulation of many somatic mutations over a lifetime. Yet there are patterns of cancer development that are marked by one or a few major mutation events.[3] In contrast to genomic signatures over a large scale, genomic analysis of cancer patients has revealed a pattern of localized clusters of point mutations.[4] This pattern has been termed kataegis, for thunderstorm. This pattern involves the clustering of substitutions at C:G base pairs on the same DNA strand over approximately a kilobase. It has been shown that AID/APOBEC-catalyzed cytidine deamination near DNA breaks contributes to this pattern. These substitution hotspots are often sites of rearrangment as well.[5]
Originally found in a study on breast cancer, this mutation pattern has been found across 30 human cancer types. The introduction of a double-stranded DNA break in yeast increases the likelihood of developing this mutational pattern but a double-stranded break is not sufficient for kataegis development.[4]
