Discuss the impact of ambient air pollution exposure on human health.
The purpose of a literature review is to identify, define, and clarify a problem, gap in knowledge, or issue to be addressed by the current analysis. In doing so, it should provide an overview of the state of knowledge on the topic through a synthesis of previous research. A literature review should survey appropriate, relevant, and up-to-date sources. It also should persuade the reader of the scholarly significance and need for the research gap that it identifies.
Organization (25%):
A well-organized literature review will guide the reader through the scholarly conversation surrounding a topic and set up the specific contribution(s) the material makes to that conversation. The literature review should employ a broad-to-narrow structure, opening with context for the problem or issue the analysis will address, then explaining relevant relations, themes, and trends in existing literature, and ultimately highlighting a gap. When appropriate (often at the end of the literature review), the literature review will present a research question or hypothesis and offer suggestions on research direction. Paragraphs or sections should synthesize groups of related sources according to concept, theory, or methodology, rather than summarizing sources one at a time. A well-organized literature review will exhibit coherence, demonstrated by headings, effective transitions, a logical flow of information within and among paragraphs, and balance among its various components.
Idea Development (25%):
This refers to the way the writer uses prior scholarship to develop ideas throughout the literature review and within its paragraphs and/or sections. A well-developed literature review will analyze and critically evaluate the literature, utilizing details and examples from sources to provide evidence for its claims and to elaborate key points. It should go beyond superficial evaluations to provide commentary characterized by depth and complexity.
Communication Style (15%):
This generally refers to the choices that the writer makes for specific audiences. This may include features like tone, sentence length and structure, phrasing, and word choice. The style should be appropriate for the research area (e.g., use of 1st or 3rd person) and should employ a formal and professional tone, active voice, and precise terminology.
Conventions (15%):
This generally addresses issues dealing with writing convention, citation style, and formatting. Features may include grammar, mechanics, usage, citation, punctuation, formatting, and capitalization.
