Lewis-Beck, Alan Bryman and Tim Futing Liao, editors. A systematic review is not a traditional literature review, but a self-contained research project that explores a clearly defined research problem using existing studies.
As such, researchers using this design can only employ a relatively passive approach to making causal inferences based on findings.. Lack of information can severely limit the type of analyzes and conclusions that can be reached.
In addition, the more dissimilarity there is in the results among individual studies [heterogeneity], the more difficult it is to justify interpretations that govern a valid synopsis of results.
However, you can get a sense of what to do by reviewing the literature of studies that have utilized the same research design.
This can provide an outline to follow for your own paper.
Causal effect (nomothetic perspective) occurs when variation in one phenomenon, an independent variable, leads to or results, on average, in variation in another phenomenon, the dependent variable. Subsequent experimental designs have used more groups and more measurements over longer periods. California State University, Fresno, 2006; Kirk, Roger E. The focus is on gaining insights and familiarity for later investigation or undertaken when research problems are in a preliminary stage of investigation. This allows the researcher to measure change in variables over time.
Often used in the medical sciences, but also found in the applied social sciences, a cohort study generally refers to a study conducted over a period of time involving members of a population which the subject or representative member comes from, and who are united by some commonality or similarity. Descriptive research designs help provide answers to the questions of who, what, when, where, and how associated with a particular research problem; a descriptive study cannot conclusively ascertain answers to why. True experiments must have control, randomization, and manipulation.. New York: Columbia University Press, 1999; Chapter 2: Research Design, Experimental Designs. (London, England: Sage, 2006), pp, 101-110; Experimental Research. Exploratory designs are often used to establish an understanding of how best to proceed in studying an issue or what methodology would effectively apply to gathering information about the issue.. It is a type of observational study sometimes referred to as a panel study.
Cohorts can be either "open" or "closed."Cross-sectional research designs have three distinctive features: no time dimension; a reliance on existing differences rather than change following intervention; and, groups are selected based on existing differences rather than random allocation. The main objectives of meta-analysis include analyzing differences in the results among studies and increasing the precision by which effects are estimated.
The cross-sectional design can only measure differences between or from among a variety of people, subjects, or phenomena rather than a process of change. A well-designed meta-analysis depends upon strict adherence to the criteria used for selecting studies and the availability of information in each study to properly analyze their findings.
The new interventional strategies are carried out, and this cyclic process repeats, continuing until a sufficient understanding of [or a valid implementation solution for] the problem is achieved.
The protocol is iterative or cyclical in nature and is intended to foster deeper understanding of a given situation, starting with conceptualizing and particularizing the problem and moving through several interventions and evaluations. “Exploratory Analysis of the World City Network.” The purpose of a historical research design is to collect, verify, and synthesize evidence from the past to establish facts that defend or refute a hypothesis.
