Among a group of disabled women aged 65 and older who were tracked for several years, those who had a vitamin B12 deficiency were twice as likely to suffer severe depression as those who did not. (American Journal of Psychology 157 [2000]:715)a)Explain why this is an observational study and not an experiment.b)Who were the subjects of the study

The correct answer to this open question is the following.

According to your question, there are only two parts to be answered, a) and b).

Being that the case, we can comment on the following.

A) This is an observational study and not an experiment because the research was only limited to observation, participants never receive any kind of treatment or another interaction to experiment with them.

B) Who were the subjects of the study?

The subjects of this study were women aged 65 and older who were tracked for several years. The observation revealed that those women who had a vitamin B12 deficiency were twice as likely to suffer severe depression as those who did not.

So, according to the American Journal of Psychology, these were the women observed during the study. There were no more experiments, interactions, or activities applied to them in order to consider it an experiment.

Let's remember that in order to consider an experiment as such, there has to be another component of the study, and the experimental part of it that has to be tested and proved passing the scientific method to conclude in something valid.

Taken from the poem “Abuelito Who” by Sandra Cisneros, the author has used the figurative language of “coins” and “rain” in lines 1, 20, and 21 in order to describe her memories about her grandfather. Cisneros has used simile, which is a figure of speech, throughout the poem. The main function of simile is to make a comparison to show the similarities between two different things. Moreover, simile is usually accompanied by words such as “as” and “like”. In the text, there are two examples of this figure of speech: “Abuelito who throws coins like rain” (line 1)/ “is the rain on the room that falls like coins” (line 21). Simile has helped the author develop the meaning of the poem, that is, to narrate about particular memories she has of her grandfather or “abuelito”, an affectionate term for a grandfather in Spanish. For instance, Cisneros used figurative language and simile in line 1 to describe how her grandfather played with her making coins fall like raindrops from above.

Prospective research subjects who are not able to comprehend information, deliberate, and make decisions about participation in a proposed research study have Cognitive or communicative vulnerability.

Option A

Explanation:

Prospective research subject are those who are taken as subject for the purpose of research on the objective of prospective. When the subjects of Prospective research lack ability in some manners to make an informed choice, the incapacity demonstrated here is remarked as the Capacity-related cognitive vulnerability.

When the subject of prospective research have the above mentioned capacity, in lieu of which, because of limited ability for communication, the subject cannot communicate with researchers and the latter are not able to exercise their capacities effectively, such inability is remarked as the Communicative vulnerability.

Explanation:

- Only think positively. Do not ever think of "what if" s because this will make you think negatively and stop you from doing your job.

- One strategy I have is writing lots of different positives messages in a paper and cutting out each of them. Put them in anywhere you want and take one each day. This will make you start your day positively.

trip the circuit cut of the current electricity then sense the current leakage

Explanation:

you have the trip the circuit so theirs no power to have electricity  and that a sign that like tells you theirs a leakage or the insulation is to old then you cut off the electricity so theirs no electricity running and sense the current leakage so the GFCI wont trip anymore

Before this decision to revoke the designated list of recognized subjects, higher education institutions demanded all learners to achieve at least 50% in four specific designated subjects that were the same for all colleges/universities.

However, as it didn't make sense for all of these institutions to require the same entry admissions, this requirement had to be changed. As of now, the student is required to achieve the same percentage in any four subjects from the list of 20-credit subjects which does have some implications.

The advantage is that there will be a higher number of students with better percentages applying for various high education institutions. This change is there to make it easier for students to get in their desired university and attain the education they want. This will also allow them to focus only on those most important subjects for them and their studies instead of studying something they might not even need for their career.

On the other hand, a disadvantage is that students might pick subjects they find easiest just in order to get into a university and those subjects might not provide them with appropriate strategies for thinking and learning that otherwise designated subjects might have. Additionally, they might not even be allowed to choose as some higher education institutions will have their own set of designated subjects and minimum requirements that might not coincide with the student's choices.
