The ecological validity of both papers should be considered similar as they both employ the same methodology. Studies on the MNS provide inconsistent results, a systematic review by Hamilton (2013) found that of twenty-five studies on the MNS found twelve studies supporting a normal MNS, six studies suggesting an abnormal system and seven studies with mixed results. The use of studies from six different methods including EEG and fMRIs, found that every method provided results both supporting the

among pregnant teens is 90% throughout the United States ("Drop Out Rates Among Pregnant Teens."). This rate is even higher for African American teens or teens from disadvantaged backgrounds. Hikiela Williams was in a constant battle against these statistics. As a teen parent, Hikiela had to demonstrate work ethic and determination in order to achieve her goal of becoming a nurse. Her early life was not easy and several different events influenced her to becoming a nurse. Hikiela not only strived to

After analysing key components of each potential market a final weighted index (as seen in Figure 7, under 5.1 Weighted Index) was generated in order to evaluate the important variables as well as make a more informed and equitable decision for Queen’s Petfood. Figure 7 shows 5 weighted variables against each potential market with an acquired score to resemble how this market will best meet the needs of Queen’s Petfood. The variables chosen for the weighted index include; potential market, disposable

Figure 4.2.1.3 The Guttmann-Kaiser rule and the Cattel scree test were used in determining the number of factors to be extracted. Guttmann-Kaiser rule suggests that only factors with an eigen value greater than one should be retained whilst the Cattel scree test suggests that all further components after the one starting the elbow should not be included. Applying these criteria on the number of principal components to be extracted suggests that seven (7) components should be extracted.

Once the failure mode is determined, the team will look at the three categories of likelihood, occurrence, and detection. They will also exam the severity of the occurrence if the process was to fail. Each of these categories will be assigned a score between 1 and 10. A score of 1 would have the least likelihood of occurrence, or detection, and minimal severity. A score of 10 would have the greatest chance of occurrence, or detection and a more severe reaction. These scores would then be used to

Madelyn Lashinis Term Paper Article Summary Sexual Selection: Pipefish In this research, they looked at many observations that took place with sexual selection in pipefish. They looked into how and where breeding took place, how long the cycle of sexual selection took, and how fast the pipefish grew. The researchers used different waters (Portugal and Ireland) and the different temperatures of waters. That way it gave them more information to learn and choose from. Their hypothesis stated that the

Results The results of the study are shown in Appendix A labeled, Figure 1. The trend was constant prior to the presentation of the token economy. After the downward trend in distance in the second token economy, a steady upward trend was present. The distance the participant ran in miles is depicted along the y-axis and the observations are shown along the x-axis. The observations are split into 5 sections. The first section is titled “Baseline A” prior to any reinforcement given. The second

population or a sample; explain your answer. Sample is made up of of the raw data collected from 500 patients which is the sample and 67% is the sample statistics. Bennett, Briggis, & Triola (2009) the raw data is collected from a subnet of patient with high cholesterol (p.3). Which indicate this as a sample from the raw data and sample statistics. b) An investigation of 150 randomly selected local restaurants concluded that 42% of local

I then decompose the data for each individual to determine whether there was consistency between 1st level and 2nd level responses. I matched each 1st level response with the appropriate 2nd level response. I called the levels consistent if both 1st and 2nd level responses placed responsibility on society or both placed responsibility on the individual. In any other case, I called the levels inconsistent. Surprisingly, I discovered that 36.5% of responses were inconsistent. This suggests that the

Question 2: The design portrayed in this example is a non-equivalent control group posttest-only design where each exam presented during the semester functions as a posttest measure. The teacher is utilizing one of the classes as a control group and one as the treatment group (for example, the weekly quiz group). The teacher is subsequently taking posttest measures by giving them exams. Since the participants were not randomly assigned to the two conditions and instead preferred the section of
