I am in Research this semester and in need of finding websites to do research such as literature reviews, etc. Most of the sites I've found are members only or want to sell subscriptions. Any help would be most appreciated.
You will most likely have to use your school or hospital library to do a literature search through CINAHL, medline, etc. and then find the actual journal volume in your library.
One site that I have found that provides many full text articles is www.medscape.com. There is a section of medscape specific for nursing.

An ideal research design provides assurance to both the investigator and those who use the information that the study results mean what they say, i.e., that the treatment or intervention employed either did or did not have the intended effect. To achieve this end, the design must first be conducted prospectively, i.e., the treatment must be applied and the effect(s) observed after subjects are selected and assigned (as opposed to retrospective or ex post facto designs, which are all nonexperimental). Additionally, all prospective research aims to provide the following:
Manipulation of the independent variable (usually by group assignment)
Observation and measurement of the changes, if any, in the dependent variable
Control of all other variables except for the dependent (outcome) variable

Statistical significance only tells the researcher how likely it is that an observed finding could have occurred by chance. It does not say anything about magnitude of the effect observed. Effect size is a name given to a group of statistics that measure the magnitude of a treatment effect. In many cases, effect size is a better measure of research outcomes than the significance level. This is because with large samples, one can observe statistically significant group differences even when only a tiny effect is present. Unlike significance tests, effect size indices are independent of sample size.
Effect Size Statistics. The most commonly used effect size estimate is Cohen's d. Cohen's d is computed by dividing the mean difference between groups by the pooled standard deviation. Cohen's d can also be computed from the value of the t-test of the differences between groups means. An alternative measure of effect size is the point-biserial correlation between the dichotomous independent variable and the continuous dependent variable. This coefficient is called the effect size correlation or effect size r.

Internal validity refers both to how well a study was run (research design, operational definitions used, how variables were measured, what was/wasn't measured, etc.), and how confidently one can conclude that the observed effect(s) were produced solely by the independent variable and not extraneous ones. In experimental research, internal validity answers the question, "Was it really the treatment that caused the difference between the subjects in the control and experimental groups?" In descriptive studies (correlational, etc.) internal validity refers only to the accuracy/quality of the study (e.g., how well the study was run)...
External validity represents the extent to which a study's results can be generalized or applied to other people or settings. Campbell and Stanley (cited in Isaac & Michael, 1971) have identified 4 factors that can adversely affect a study's external validity...
I would really appreciate anyone who could do a 12 question interview with me who is doing evidenced based research in a clinical setting or a full time research nurse. There may be a possiblity that it may not be that many.If you are unable to answer the question we just go onto the next. I am just having a horrid time finding anyone who fits the bill or is willing to do it. It is for my Nursing Roles and Values course at WGU. There is no one locally and I have contacted 4 different universities who have not responded or their rep is out of town. My time is running out for this taskstream assignment.

what is field research?
field research - sometimes regarded as synonymous with the more comprehensive term of ethnography, sometimes with its essential constituent part of participant observation - may be described as -"...the process in which an investigator establishes a many sided and relatively long term relationship with a human association in its natural setting for the purpose of developing a scientific understanding of that association." (lofland & lofland, 1984)....
