Another question that is common relates to processed meat products. Once a processed meat product (ham, hot dog, lunchmeat, etc.) package is opened, the product should be good for up to seven days unless another type of date is on the package and has passed. After the seven days, the product should not be consumed.
Primary research is any type of research that you go out and collect yourself. Examples include surveys, interviews, observations, and ethnographic research. A good researcher knows how to use both primary and secondary sources in her writing and to integrate them in a cohesive fashion.
Examples include; an article where an author has collected data herself and presents that data; or a book where an author develops and presents a new theory. How to identify primary sources. For empirical articles, the author will describe her data collection process (Method, Results sections). For theoretical articles or books, the author will present the theory as her own. Whatâs not primary. Articles which describe the work of others.
