Literature Review Article Critique Jocelyn Claudio Widener University September 25, 2016 Overview The authors of this literature review evaluated studies completed on adults who were 50 years or older and also experienced trauma as a child. They reviewed the impact childhood trauma has on their mental and physical health as older adults. They collected findings from 23 studies that were published between 1996 through 2011 and concluded that childhood trauma did in fact have negative effects

What should be named in the report Methods size of study area sampling design (e.g., use of spatial or temporal blocks) number of stations spacing between stations or station density method of estimating effective trapping area (e.g., size of buffer width) objective method of identifying individuals sampling period occasion length used for analysis (Foster & Harmsen 2012) camera types and settings (e.g. Kelly et al. 2008) Results trap effort (number of trap‐nights; see text

To distinguish between different sampling methods The concept of the sampling distribution To compute probabilities related to the sample mean and the sample proportion The importance of the Central Limit Theorem 7-2 Why Sample? DCOVA Selecting a sample is less time-consuming than selecting every item in the population (census). An analysis of a sample is less cumbersome and more practical than an analysis of the entire population. 7-3 A Sampling Process Begins With A Sampling

Analysis and findings We have four proposals as outcomes of the analysis. Detailed descriptions and explanation are listed below: Proposal1:People having higher income prefer to outdoor activities. According to the percentage of outdoorman in ascending order, we separate the areas into 5 intervals. And based on the statistics of the average income in each area, we compute the average incomes in five intervals to see if there is a tendency related to the proportion of outdoorman. Figure1 Positive

Simple Random Sampling vs. Stratified Random Sampling Sampling involves selecting a subset of elements from the population. In this case, Stratified Random Sampling, and Simple Random Sampling plans are compared as data collection methods for a sample that a researcher would consider using for a business survey for a marketing/advertising campaign. Simple Random Sampling is a sampling procedure whereby the researcher defines the target population and then selects a sampling frame from the population

The selection criteria were based on sticking to the key PICO words. Studies that involved both kids and adults were avoided, as the population being studied was strictly adults. Of the final 11 articles in PubMed, three RCT’s, and one SR/MA were selected. Two of those eleven were studying babies/children in conjunction with adults, so they were excluded. One study focused only on the prevention of CDI, and there was no mention of AAD, so that was eliminated in order to stick to the dependent

Ambidexterity Amongst Students and Athletes MATH 141 (Prof. An) Final Project December 2015 Romeo Ardimento, Lorraine Jabouin, Christopher Kremer, Fiona Macleod Introduction/Background Being Ambidextrous can be quite useful; particularly for athletes and musicians. Many sports require the use of both hands, as do many instruments. For this reason our team decided to determine the difference in ambidexterity, if any, between people who are either athletes or musicians, and individuals who are not

4.2 Sample size Size of the sample group is needed to be specified properly due to the goal is to make inferences about the population from the sample. The appropriate sample size can be resulted in terms of the reliability of the study, especially empirical study. Therefore, how many samples can satisfy the target? In addition, a smaller sample size leads to a higher error of the sampling when compared with a bigger size. Even if an increasing of sample size can diminish the error, after it goes

Victorio Anton NURS 307 Dr. Zirkle Research Critique Introduction This research was conducted in order to evaluate the effect of a perioperative safety checklist on perioperative safety standards and the quality of inter-professional cooperation from the staff’s perspective. A 19-item questionnaire was used to survey employees’ attitudes regarding safety-relevant aspects of the perioperative period, work processes, and quality of inter-professional cooperation before and 3 months after the implementation
