Or, does is merely add more of the same thing being said. The purpose is to develop a body of literature that establishes a contrarian viewpoint.
Have I cited and discussed studies contrary to my perspective. ZnO NPs also failed to induce skin sensitization in guinea pigs during or up to 48 h after the elicitation phase after an induction phase that involved weekly application of NPs for 3 weeks Kim et al.
Do not use extensive quotes as a substitute for your own summary and interpretation of the literature. The theoretical literature review helps to establish what theories already exist, the relationships between them, to what degree the existing theories have been investigated, and to develop new hypotheses to be tested.
In this Background section, make the topic interesting by explaining it in plain language and by relating it to actual or potential practical applications. Locate your own research within the context of existing literature [very important]. Consider Whether Your Sources are Current Some disciplines require that you use information that is as current as possible.
So if your paper still does not appear to be defined by a central, guiding concept, or if it does not critically analyse the literature selected, then you should make a new outline based on what you have said in each section and paragraph of the paper, and decide whether you need to add information, to delete off-topic information, or to re-structure the paper entirely.
This review of the professional literature relevant to your research question will help to contextualize, or frame, your research. I encourage you to use such subheadings, which will make it easier for you to write the review and easier for others to read it. Choose those studies which are most relevant and most important.
When applied to human skin sample in vitro for 48 h, none of these ZnO NP formulations penetrated beyond the superficial layers of the stratum corneum into the intact viable epidermis. Look for repeating patterns in the research findings.
This suggests that the likelihood of NPs causing cytotoxicity or pathology in internal organs or tissues is very low since systemic absorption is highly unlikely.
Were the results effectively interpreted and reported. What questions about the field has the review sparked. Problems of interpretation arise when researchers get a statistically non-significant effect. Writing the conclusion What is a review of literature. The true value of the effect is the average value of the effect in the whole population, or the value of the effect you would get if you sampled the whole population.
Mice that were orally administered TiO2 daily for 6 months exhibited lower body weight gain and significant kidney pathology attributed to NP-induced oxidative stress Gui et al. The literature review may also identify gaps or controversies in the literature and topics needing further research.
Occasionally you will be asked to write one as a separate assignment sometimes in the form of an annotated bibliography—see the bottom of the next pagebut more often it is part of the introduction to an essay, research report, or thesis.
Methodology -- were the techniques used to identify, gather, and analyze the data appropriate to addressing the research problem. If it also runs counter to your hypothesis, you may want to critique it in your review. When you write a literature review, you summarize the arguments and ideas of others.
In a literature review, the sources are the main focus. A review is a required part of grant and research proposals and often a chapter in theses and dissertations. Never copy any examples however as this would be considered plagiarism.
Is its significance scope, severity, relevance clearly established.
Similar findings were reported in a study with a similar protocol, where in addition to these pathological features, retinal atrophy was also observed in the high dose group Park et al. If you are uncertain which style to use, ask your professor.
Should I evaluate the sources. Here are several strategies you can utilize to assess whether you've thoroughly reviewed the literature: One single publisher Elsevier, for instance, holds over 14 million research papers and published overjournal articles in just one year.
Be wary of generalizing results from novice athletes to elites. These effects were comparable in magnitude between the different NP preparations. Generally, the purpose of a review is to analyze critically a segment of a published body of knowledge through summary, classification, and comparison of prior research studies, reviews of literature, and theoretical articles.
This guide will provide research and writing tips to help students complete a literature review assignment. A literature review may consist of simply a summary of key sources, but in the social sciences, a literature review usually has an organizational pattern and combines both summary and synthesis, often within specific conceptual categories.
A summary is a recap of the important information of the source, but a synthesis is a re-organization, or a reshuffling, of that information in a way that informs how you are. literature review As part of the planning process you should have done a LITERATURE REVIEW, which is a survey of important articles, books and other sources pertaining to your research topic.
Now, for the second main section of your research report you need to write a summary of the main studies and research related to your topic.
Peer review is the evaluation of work by one or more people of similar competence to the producers of the work ().It constitutes a form of self-regulation by qualified members of a profession within the relevant elleandrblog.com review methods are employed to maintain standards of quality, improve performance, and provide credibility.
