A bibliography is the list of references at the end of your work which tells the reader which sources you used to develop your ideas and arguments when you conducted your research. These normally tell the reader who the author was, the title of the work and where it is published. To add extra credibility to your paper and your research you are sometimes asked to produce an apa bibliography, this differs from the standard bibliography by asking you to summarize or evaluate the reference that you are listing. This means that you add a short; 150 words maximum, summary of what the document was about or evaluate it with regards to its quality, and usefulness to your research; sometimes you have to do both.
Like any other part of your academic paper it has to be produced within specific rigid guidelines; so an annotation in APA style has to be written in that specific style and following your tutors guidance with regards to the type of annotations required.
The authors, researchers at the Rand Corporation and Brown University, use data from the national Longitudinal Surveys of Young Women and Young Men to test their hypothesis that nonfamily living by young adults alters their attitudes, values, plans, and expectations, moving them away from their belief in traditional sex roles. They find their hypothesis strongly supported in young females, while the effects were fewer in studies of young males. Increasing the time away from parents before marrying increased individualism, self-sufficiency, and changes in attitudes about families. In contrast, an earlier study by Williams, cited below, shows no significant gender differences in sex role attitudes as a result of nonfamily living.
