Literature Review (Biometrics)Research Paper
1. Introduction o Define or identify the general topic, issue, or area of concern, thus providing an appropriate context for reviewing the literature. o Point out overall trends in what has been published about the topic; or conflicts in theory, methodology, evidence, and conclusions; or gaps in research and scholarship; or a single problem or new perspective of immediate interest. o Establish the writer’s reason (point of view) for reviewing the literature; explain the criteria to be used in analyzing and comparing literature and the organization of the review (sequence); and, when necessary, state why certain literature is or is not included (scope)
2. Body o Group research studies and other types of literature (reviews, theoretical articles, case studies, etc.) according to common denominators such as qualitative versus quantitative approaches, conclusions of authors, specific purpose or objective, chronology, etc. o Summarize individual studies or articles with as much or as little detail as each merits according to its comparative importance in the literature, remembering that space (length) denotes significance. o In assessing each piece, consideration should be given to:
. Provenance – What are the author’s credentials? Are the author’s arguments supported by evidence (e.g. primary historical material, case studies, narratives, statistics, recent scientific findings)?
. Objectivity – Is the author’s perspective even-handed or prejudicial? Is contrary data considered or is certain pertinent information ignored to prove the author’s point?
. Persuasiveness – Which of the author’s theses are most/least convincing?
. Value – Are the author’s arguments and conclusions convincing? Does the work ultimately contribute in any significant way to an understanding of the subject? o Provide the reader with strong “umbrella” sentences at beginnings of paragraphs, “signposts” throughout, and brief “so what” summary sentences at intermediate points in the review to aid in understanding comparisons and analyses.
· Conclusion o Summarize major contributions of significant studies and articles to the body of knowledge under review, maintaining the focus established in the introduction. o Evaluate the current “state of the art” for the body of knowledge reviewed, pointing out major methodological flaws or gaps in research, inconsistencies in theory and findings, and areas or issues pertinent to future study. o Conclude by providing some insight into the relationship between the central topic of the literature review and a larger area of study such as a discipline, a scientific endeavor, or a profession.
