Part 1: Initial Blog Post on an Organ SystemNow that you have had a chance to study the organ systems of the body, choose one system and research it further. Find a credible and reliable, scientific website that augments what you have already learned about that particular organ systemShare the website with the class by writing a full paragraph summary (150 words minimum) of what you have learned or have found particularly helpful when reviewing the website. Do not copy and paste directly from the website. This blog should be written in your own words. Also required within the initial blog post is sharing the website (specific URL) and what you have learned from this resource and/or have found particularly helpful when reviewing the website.Do not copy and paste directly from the website. This blog should be written in your own words.Any content and paraphrased information from the resource (URL) must be properly cited per APA including the specific URL (website) you are recommending. The blog post must be directly posted in the classroom; please do not upload a Word document only.

Respond to a colleague's post by explaining an insight you gained from this week's Resources that addresses a topic in your colleague's post. Please use the resources to support your postColleague: Jacqueline Classify Research DesignKohl et al (2011) conducted a quasi-experimental study where parenting practices and maternal depression is examined over a 36 month time period to determine their association. The same sample of 1536 mother-child pairs were used during the entire study (Kohl el al, 2011, p.215). The study is considered quasi-experimental because it uses the same group of mother-child pairs at different times. Limitations of the StudyOne of the limitations of the Kohl et al (2011) study is that the sample used only mother-child pairs where the child stayed in the home with the mother following the investigation of maltreatment (p.221). This limits the experiences gathered and analyzed to these specific circumstances. Whereas, children removed from their home were not analyzed, and their experiences were most likely not the same as those who remained in the home following maltreatment. Also, the entire study relies on the mothers self reporting which leaves room for dishonesty or reluctance to share information.Concerns Regarding Internal Validity and CausalityThe concerns I have surrounding the internal validity and the ability of the study to draw conclusions about causality is that the study is completely dependent on the word of its participants which can never be proven true beyond the shadow of a doubt. It is possible for a mother to be reluctant to share the truth of her experience which jeopardizes the validity and ability to draw conclusions about causality.Concerns about Generalizability of the Study and What may Limit itIn the Kohl et al (2011) study the concerns I have for generalizibility is that the results can only be considered to be true for those who fit within the parameters of the sample used (p.216). Therefore, the research design is limited to mother-child pairs where the child is between the ages of three to 10, and who remained in the home for at least a 36 month span after maltreatment being investigated.
