MeSH terms have ‘automatic explosions’, meaning ??
MeSH terms have ‘automatic explosions’, meaning PubMed automatically searches the MeSH headings as well as the more specific terms beneath that heading in the MeSH hierarchy. This is known as the explosion feature
Would usually be indicated as “research” on the header of the article but this is not always the case as it depends on the journal
Characteristics of a Research Article
__ can search and include everything under the tree, whereas, no explosion features focuses on one topic
Explosions
Study design are usually indicated in the title but this is not
always the case as it depends on the author/s
Characteristics of a Research Article
The abstract is an important component for research articles as well as other types of literature. The presence of an abstract might indicate that this type of literature is a research article
● May be structured or unstructured

○ Introduction or Background - shows what has been done before
○ Methods - includes subheadings, participants, and sample size

According to Degree of Variable Manipulation
According to Time Duration
According to Sources of Information
Research According to Sources of Information
Primary Research
Secondary Research
The data is collected directly from the source, that is, it consists of primary, first-hand information
Primary Research
Developed with information from secondary sources, which are generally based on scientific literature and other documents compiled by another researcher
Secondary Research
Formulating new general concepts, establishes new theories
■ Example: philosophical Dissertations
Theoretical Research
Addresses a specific research problem and
draws on theory to generate scientific knowledge
Applied Research
For subjects not well understood or researched
■ Relies less on theory and more on data collection
■ What’s inside the black hole?
Exploratory Research
Defines the characteristics of a particular phenomenon
Descriptive Research
Similar to descriptive research, but establishes cause-and-effect relationships
Explanatory research
Identifies the relationship between two or more variables
Correlational Research
Has a linguistic-semiotic basis for discourse analysis, interviews, surveys, records, and participant observation
Qualitative Research
Variables are manipulated under strictly controlled conditions in order to identify or discover its effect on another independent variable
Experimental Research
Uses a mathematical, statistical, and computer aided tools to measure phenomena
Quantitative Research
Uses a combination of quantitative and qualitative data, usually presented through a joint display analysis
Mixed Methods Research
