In this article, it talks about cholera outbreaks in Vietnam again. Cholera is contagious that causes diarrhea. It often happens in poor and high populated counties that have a difficult time getting safe to drink water such as Vietnam. From 1979 to 1996, there was high amount of people in Vietnam with cholera. In 1997 there was vaccination for it so the amount decreased, however in 2006 the amount of people affected increased again. The cause was linked to food and unsanitized water from the river-

Method Activity 1. Correlational vs. Causation The topic “Keeping a Diary Doubles Diet Weight Loss” seems to offer a solution in relation to weight loss and keeping a diary. Therefore, without reading the article, the topic offers an impression of a causal claim. Causal claims are supported by having independent and dependent variable. The independent variable is the factor that can be manipulated to result to change on another factor (Christensen, Johnson & Turner, 2014). In other words, the

duty to ensure: (1) all subjects were required to conduct physical readiness training (PRT), and (2) all subjects underwent through the same diagnosis. Limitations The limitations of this study are related to the study design, study population, and sample size. A cross-sectional design was more convenient in this study due to time, cost and technical constraints. However, a prospective longitudinal study would definitely provide more insights. In fact, a cross-sectional study studies the relationship

The Effect of the Size of a Superworm Introduction: For this experiment we were given superworms to experiment on. It was up to use students to decide what experiment we were going to perform on the worms. My group and I decided that we were going to observe how the size of the worms would affect how they reacted towards natural objects such as: sticks, rocks, leaves, mulch, and a pinecone vs an artificial object such as a straw. While doing this experiment, we observed the independent variable,

between true experimental and quasi-experimental research design. Provide examples in your answer. (265 words) True experimental and quasi-experimental research designs are the two most common forms of research design. While they both share similar elements, such as measuring participant results to test the hypothesis, there are also significant differences between true experimental and quasi-experimental research designs (The Regents of the University of Michigan, 2013 ). True experimental research

Identification of Articles Through my search for articles I discovered that there were no studies of randomized controlled trials, and there were therefore no systematic reviews or Meta analyses of randomized controlled trials related to my topic question. This limited the variety and amount of studies that could be utilized to help answer my question. I found a variety of observational studies that addressed melanoma screening that did not address my exact question I was trying to address.

According to Dynamic influences of culture on cooperation in the prisoner’s dilemma (2005) by Wong & Hong, cultural symbols affect people’s behavior in specific situational contexts. In order to substantiate this hypothesis, the authors used a three by two between-subjects method, with one hundred and seventy-one participants. In the study, the independent variable was icons, either from American, Chinese, or neutral backgrounds. Additionally, the three dependent variables studied were cooperation

length of stay, and healthcare associated infections. To systematically review the literature and establish an overview of associations between characteristics of the nurse work environment (nurse staffing ratios and nurse-physician collaboration). Design Methods The article by Aiken et al. (2014), used an observation study approach with a cohort study; the study was during the time of 2009-2010, and the other was based over a 30-day period. The research article directed by Ball et al. (2013) used
