Day 08 ActivityFisher & HughesSeptember 21, 2018Study
A study was conducted to determine the effects of alcohol on human reaction times. Fifty-seven adult individuals within two-age groups were recruited for this study and were randomly allocated into one of three alcohol treatment groups – a control where the subjects remain sober during the entire study, a moderate group were the subject is supplied alcohol but is limited in such a way that their blood alcohol content (BAC) remains under the legal limit to drive (BAC of 0.08) and a group that received a high amount of alcohol to which their BAC may exceed the legal limit for driving. Each subject was trained on a video game system and their reaction time (in milliseconds) to a visual stimulus was recorded at 7 time points 30 minutes apart (labeled T0=0, T1=30, T2=60 and so on). At time point T0, all subjects were sober and those in one of the alcohol consumption groups began drinking after the first measured reaction time (controlled within the specifications outlined). The researcher is interested in determining the influence alcohol and age (namely, is reaction time different for those in the 20s versus 30s) has on reaction times.
The task for today is to do a complete analysis for this study and dig into the effects of alcohol, age and time have on reaction times.Data input and wrangling

Chapter 16: Inference for Regression
Climate Change
The earth has been getting warmer. Most climate scientists agree that one important cause of the warming is
the increase in atmospheric levels of carbon dioxide (CO2), a green house gas. Here is part of a regression
analysis of the mean annual CO2 concentration (CO2) in the atmosphere, measured in parts per thousand
(ppt), at the top of Mauna Loa in Hawaii and the mean annual air temperature (Temp) over both land and
sea across the globe, in degrees Celsius.
Let’s first read the dataset into R
climate <- read.table('Climate_Change.txt', sep = '\t', header = TRUE)
and take a look at the data structure:
str(climate)
## 'data.frame': 29 obs. of 3 variables:
## $ year: int 1980 1981 1982 1983 1984 1985 1986 1987 1988 1989 ...
## $ Temp: num 14.2 14.3 14.1 14.3 14.1 ...
## $ CO2 : num 339 340 341 342 344 ...
We see three variables, which are year, Temp (mean annual air temperature) and CO2 (mean annual CO2
concentration), and there are 29 observations in each variable.
We now take Temp as the response variable and CO2 the predictor variable, to study their relationship. To see
if linear regression is appropriate, we make a scatterplot of Temp against CO2
plot(climate$CO2, climate$Temp, xlab = 'CO2 Concentration', ylab = 'Temperature')

It seems reasonable to fit a linear model to the dataset, because both variables are quantitative, the data
points show a linear pattern, and there is no outlier. So, let’s fit the model:
imod <- lm(Temp ~ CO2, data = climate)

which contains a lot of information. We see that R2 = 0.6776 and the SD of residuals se = 0.09847 (the
estimator of population standard deviation σ) with 27 degrees of freedom. In Coefficients section we
see the intercept b0 = 10.71 and the slope b1 = 0.01. Their standard errors are SE(b0) = 0.481 and
SE(b1) = 0.00134. Their t-test statistics are t0 = b0/SE(b0) = 22.26 and t1 = b1/SE(b1) = 7.534. Their
corresponding (two-tailed) p-values are very small (<2e-16 and 4.19e-08). As a result, we reject H0 : β1 = 0
and conclude there is a positive correlation between Temp and CO2. The b1 = 0.01 can be interpreted as
follows: The air temperature will increase by 0.01 degrees Celsius on average if the CO2 concentration in the
atmosphere increases by 1 p ...

Shortcut Design Method for Multistage Binary Distillation via MS-ExceIJERA Editor
Multistage distillation is most widely used industrial method for separating chemical mixtures with high energy consumptions especially when relative volatility of key components is lower than 1.5. The McCabe Thiele is considered to be the simplest and perhaps most instructive method for the conceptual design of binary distillation column which is still widely used, mainly for quick preliminary calculations. In this present work, we provide a numerical solution to a McCabe-Thiele method to find out theoretical number of stages for ideal and non-ideal binary system, reflux ratio, condenser duty, reboiler duty, each plate composition inside the column. Each and every point related to McCabe-Thiele in MS-Excel to give quick column dimensions are discussed in details

COMMENTS: You wrote an interesting essay; however, it is lacking the introduction and conclusion paragraphs (1/3 deduction.) Remove the notations from the Reference List. Not all of your sources came from the UOP library and are peer reviewed, so you need to locate additional. You need a minimum of three peer reviewed sources from the UOP library. Prove your arguments using academic sources. Some paragraphs are too short, every paragraph should be five to eight sentences. You received a five point deduction for not including the introduction or conclusion.
SCORE: 10/15 Points (Deduction for not including an introduction or conclusion.)
The Inappropriateness of the Death Sentence
Add an introduction paragraph. Comment by Darlene Bennett: The introduction needs a topic sentence that describes the main idea of the paragraph, then provide background information and finally, include the thesis statement. The introduction should be five to eight sentences in length.
Thesis Statement Comment by Darlene Bennett: The thesis statement cannot be isolated by itself. You need to insert it as the last sentence of the introductory paragraph.
The death penalty, as practiced in some societies in the world, has had its positive aspects and negative aspects and my stand are that it should be abolished in any democratic state that seeks to ensure justice for both the victims of crime and the offenders.
The death sentence is against the bible and other religious guidelines Comment by Darlene Bennett: Capitalize the word “Bible.”
Death sentences against convicted criminals in the society go against the spirit and guidelines provided by religious faiths regarding our stay here in the universe. Comment by Darlene Bennett: Casual tone, stay formal and do not use first person pronouns.
Religious laws quoted in religious books prohibited the execution of man whatsoever. According to these religious laws, there is no compromise or a reason big enough to necessitate the punishment of an offender through death. The ten commandments developed by God himself in the book of Deuteronomy, under commandment five, prohibits the killing of a man. Universal religious laws concur with the Christian teaching regarding the execution of man as a way of punishment (Goldman, 2017). Comment by Darlene Bennett: This is a generalization – do all religious books state this? By Old Testament law, people were stoned for certain infractions. Be specific and provide a source for your fact. Comment by Darlene Bennett:
Religious teachings in all religion term human life as sacred and one that is not subject to limitation, in all circumstance. According to the various religions, it is God only who can terminate the life of a human being. They recommend the use of other means of justice for offenders to reform and revert back to their normal lives in the society (Goldman, 2017).
Further, no method of executing criminals is humane, all the methods are painful, inhumane and disrespectful.

COMMENTS: You wrote an interesting essay; however, it is lacking the introduction and conclusion paragraphs (1/3 deduction.) Remove the notations from the Reference List. Not all of your sources came from the UOP library and are peer reviewed, so you need to locate additional. You need a minimum of three peer reviewed sources from the UOP library. Prove your arguments using academic sources. Some paragraphs are too short, every paragraph should be five to eight sentences. You received a five point deduction for not including the introduction or conclusion.

The Inappropriateness of the Death Sentence
Add an introduction paragraph. Comment by Darlene Bennett: The introduction needs a topic sentence that describes the main idea of the paragraph, then provide background information and finally, include the thesis statement. The introduction should be five to eight sentences in length.
Thesis Statement Comment by Darlene Bennett: The thesis statement cannot be isolated by itself. You need to insert it as the last sentence of the introductory paragraph.
The death penalty, as practiced in some societies in the world, has had its positive aspects and negative aspects and my stand are that it should be abolished in any democratic state that seeks to ensure justice for both the victims of crime and the offenders.
The death sentence is against the bible and other religious guidelines Comment by Darlene Bennett: Capitalize the word “Bible.”
Death sentences against convicted criminals in the society go against the spirit and guidelines provided by religious faiths regarding our stay here in the universe. Comment by Darlene Bennett: Casual tone, stay formal and do not use first person pronouns.
Religious laws quoted in religious books prohibited the execution of man whatsoever. According to these religious laws, there is no compromise or a reason big enough to necessitate the punishment of an offender through death. The ten commandments developed by God himself in the book of Deuteronomy, under commandment five, prohibits the killing of a man. Universal religious laws concur with the Christian teaching regarding the execution of man as a way of punishment (Goldman, 2017). Comment by Darlene Bennett: This is a generalization – do all religious books state this? By Old Testament law, people were stoned for certain infractions. Be specific and provide a source for your fact. Comment by Darlene Bennett:
Religious teachings in all religion term human life as sacred and one that is not subject to limitation, in all circumstance. According to the various religions, it is God only who can terminate the life of a human being. They recommend the use of other means of justice for offenders to reform and revert back to their normal lives in the society (Goldman, 2017).
Further, no method of executing criminals is humane, all the methods are painful, inhumane and disrespectful.

I turned into a part as an understudy, yet I didn't comprehend the significance of being associated with these associations. In the present changing social insurance framework, it is so imperative to be taught and included on the present issues. The ANA has been a promoter for profession improvement and improving the wellbeing for all Americans for more than 100 years. I need to turn into an individual from this long-standing association to keep awake to-date on issues, proceed with my training, and have any kind of effect in the nursing field.

Being an advocate means a lot, at many different levels. For instance, as LVN being an advocate is hands on, RN would be collaborating with many different discipling, BSN would be all the combination and take it to a management level. As working for hospice being a patient advocate is so important at the end of life. Working with dying patients and educating families about the medications needed for end of life comfort.

Comments: Excellent paper. It’s obvious that you put quite a bit of work into this. Unfortunately, your paper needs adequate citations in the body of the text to meet our standards on plagiarism. You need to cite each textbook from your bibliography whenever you quote or use some information from the textbook or other resource. For example, writing (Jones 285) after the quote or information used means that you got it from the book whose author was Jones and the info came from page 285.
Laparoscopic cholecystectomy is a procedure in which laparoscopic techniques remove the gallbladder. It is the standard of care for symptomatic gallbladder disease, of which most are performed for symptomatic cholelithiasis. Other indications include acute cholecystitis, biliary dyskinesia, and gallstone pancreatitis.
Describe the reasons a patient might have the selected surgical procedure
The typical reason a cholecystectomy is a treatment of choice is inflammatory changes of gallbladder or blockage of bile flow by gallstones. Symptomatic cholelithiasis is the most common reason where gallstones in the gallbladder are blocking the bile flow and cause inflammation. The patient usually complains of episodic epigastric pain and right upper quadrant pain that radiates to the right shoulder. This pain is found to occur several hours after heavy meals and the patient experiences nausea, vomiting, bloating, fever, and right upper quadrant tenderness. Another condition is acute cholecystitis, where inflammation and symptoms are more prominent. The patient may have a fever, constant pain, positive Murphy's sign, or leukocytosis. Acute cholecystitis may be caused by calculous biliary tract disease with confirmed gallstones in the abdominal US. Acute acalculous cholecystitis usually occurs in critically ill patients, those with prolonged total parenteral nutrition, and some immunosuppressed patients. Patients with episodes of right upper quadrant pain (which are ‘classic' for biliary pain without evidence of cholelithiasis of US or ERCP) may also be referred for laparoscopic cholecystectomy. Gallstone pancreatitis (when small stones pass through the cystic duct) confirmed by cholangiography is another indication for laparoscopic cholecystectomy.
Describe the reasons a patient might be disqualified for this surgery and the options for the patient if any
A patient might be excluded for laparoscopic cholecystectomy due to acute general conditions that are a contraindication for any surgery such as an acute cardiac failure, uncontrolled hypertension, acute renal failure, pneumonia, etc. The condition should be treated by a primary care provider or specialist and the patient should be stable prior surgery. Additional contraindications may include the inability to tolerate general anesthesia, significant portal hypertension, uncorrectable coagulopathy, and multiple prior operations.

Pragmatism is defined as a philosophical approach in which experience is the fundamental concept. Radu explains that in pragmatism, each experience is based on the interaction between subject and object, between self and its world and represents only the result of the integration of human beings into the environment (Radu, 2011). All in all, pragmatism promotes activity based learning. Pragmatism relates to Dewey’s work in many ways. The most significant being its rejection of traditional learning, and its emphasis on solving problems in a sensible way that suits conditions that really exist rather than obeying fixed theories, ideas, or rules (Cambridge, 2016).
Progressivism is a philosophical concept belonging to ‘new education’, is ‘a Copernican revolution’ in pedagogy, promoting ‘a child-centered school’ (Radu, 2011). Radu states that Dewey’s pedagogic view is not based on his philosophical concept, but al on the social, economic and cultural realities of American society (pg. 87). Progressivism is featured around the learning capacity continuing into adulthood; Dewey called this “permanent education”. Learning is done by doing; this is because Dewey believed authentic knowledge is achieved only through direct experience. Although Dewey though some target methods were necessary when teaching, he did not believe in teachers being forced to stick to routines (Radu 2011). This idea leads to the problem-problem solving method which in short states that in order to solve problem, an individual must: define the problem, analyze the problem, determine possible solutions, propose solutions, evaluate and select a solution, and determine strategies to implement solution. The progressive theory encourages learning through discovery, this allows the learner to acquire knowledge through interest, rather than effort.
Ragu also states that there are reactions against Dewey’s progressive education. Perennialism says that permanence is the fundamental feature of the world; not change. School is intended to promote the permanent values of the past and present. Essentialists believed the main purpose of school was to prepare th.

Social Media Acts as Catalyst for Policy Change
Technologies enable people to connect by shared beliefs and social movements, rather than by just national or ethnic identification. There is no longer a location-bound or time element in global communication. We seek out those who share our beliefs, and this allows us to harness the power of ideas across borders. Conduct some research into the power of social media to effect political change and consider the following questions, sharing one recent example:
Has the advent of “technology assisted communication” contributed to an expansion of the democratic process? If so, in what way(s)? Is this approach to democratic interaction workable for the future or just a unique event?
How has social media contributed to political change? Examine this question using the example from your research.

Day 08 ActivityFisher & HughesSeptember 21, 2018Study
A study was conducted to determine the effects of alcohol on
human reaction times. Fifty-seven adult individuals within two-
age groups were recruited for this study and were randomly
allocated into one of three alcohol treatment groups – a control
where the subjects remain sober during the entire study, a
moderate group were the subject is supplied alcohol but is
limited in such a way that their blood alcohol content (BAC)
remains under the legal limit to drive (BAC of 0.08) and a
group that received a high amount of alcohol to which their
BAC may exceed the legal limit for driving. Each subject was
trained on a video game system and their reaction time (in
milliseconds) to a visual stimulus was recorded at 7 time points
30 minutes apart (labeled T0=0, T1=30, T2=60 and so on). At
time point T0, all subjects were sober and those in one of the
alcohol consumption groups began drinking after the first
measured reaction time (controlled within the specifications
outlined). The researcher is interested in determining the
influence alcohol and age (namely, is reaction time different for
those in the 20s versus 30s) has on reaction times.
The task for today is to do a complete analysis for this study
and dig into the effects of alcohol, age and time have on
reaction times.Data input and wrangling

Note, the Age variable is recorded as an actual age in years, not
the category of 20s or 30s like we want – we need to
dichotomize this variable. Also note the data is in wide format –
the reaction times (the response variables) are spread over
multiple columns. We need a way to gather these columns into a
single column. So we need to do some data processing.
First consider the below code:head(alcohol %>%

case_when is essentially a piece-wise comparison. When Age is
less than 31, you overwrite Age variable with “20s”. If the Age
is greater than 30, you replace it with “30s”. In this example we
used both a < comparison and the %in% statement we’ve seen
before just to show multiple functionality. Also note we include
30 in the 20s group and 40 in the 30s group so they are each of
5. size 10.alcohol <- alcohol %>%
mutate(Age = case_when(Age<31 ~ "20s",
Age %in% 31:40 ~ "30s") )
So the Age variable has been categorized. Now we need to
convert the data from wide to tall format. We do this with the
gather() function included in tidyverse.alcohol.tall <- alcohol
%>%
gather(key=Time, value=Reaction, c(T0, T1, T2, T3, T4, T5,
T6))
A blurb about gather There are essentially three inputs into the
gather() functions. Firstkey - Essentially provides the name of
the new variable we are going to create that consist of the
column namesvalue - Is the name for the new variable that will
house the values originally stored in the columns of interestThe
final part is a list of all the columns we want to gather, in this
case, T0, T1, T2, T3, T4, T5 and T6.head(alcohol.tall, n=10)##

## 9 9 20s Control T0 246.9
## 10 10 30s Control T0 249.1
You will now note the data is a in a tall format, which is good
for analysis.
Lastly, so R doesn’t try and treat it as a number, we tell it that
the Subject variable is a factor or categorical variable. I also put
the Alcohol variables in the order we think…alcohol.tall <-
alcohol.tall %>%
mutate(Subject = as.factor(Subject),
Alcohol = factor(Alcohol, levels=c("Control",
"Moderate", "High")))Exploratory Data Analysis
6. There are 2 categories for age, 3 categories for alcohol use and
then 7 time points to consider. Essentially (2times 3times 7 =
42) combinations to consider. Rather than look numerically we
will consider things graphically.
First we consider a plot of the Reaction times in Time based on
Alcohol treatment with Age determining the
linetype.ggplot(alcohol.tall) +
geom_line(aes(x=Time, y=Reaction, group=Subject,
color=Alcohol, linetype=Age))
Not only is this plot noisy, it is hard to determine anything.
Let’s facet based on Ageggplot(alcohol.tall) +
geom_line(aes(x=Time, y=Reaction, group=Subject,
color=Alcohol)) +
facet_wrap(~Age)
This second plot is improved but still quite noisy. Let’s plot
average profiles rather than the raw data.ggplot(alcohol.tall,
aes(x=Time, y=Reaction, group=Alcohol, color=Alcohol)) +
stat_summary(fun.y=mean, geom="line") +
facet_wrap(~Age)
These average profiles are fairly telling and maybe even a little
surprising. Overall you see the High aclohol group (blue line)
shows an increase in reaction time over the time of the study.
The Control group shows a near decrease in the 30s group but
also note the spead is only about a half a unit decrease.Model
fitting and analysis
We fit a 2 factor repeated measure model and look at the
output.fit <- aov(Reaction ~ Age*Alcohol*Time +
Error(Subject/Time), data=alcohol.tall)

First we look at the most complicated interaction term, in this
case Age:Alcohol:Time and it is NOT significant. So we follow
up by considering the two-way interaction terms. We see
Age:Alcohol and Age:Time are not significant but
Alcohol:Time is. There is an interaction between Alcohol group
and Time. Given the interactions involving Age are not
significnat, we can also consider the Age main effect, but see it
is also insignificant (F-stat 0.252 on 1 and 51 degrees of
freedom, (p)-value=0.616). Age appears to have no influence
on the reaction times. We follow up with conditional multiple
comparisons.Multiple Comparison Follow ups
Note: We have two levels of control in this study, there is an
explicit Control group and at time point T0 no subjects had been
given a treatment, so it also operates as a control. Dunnett’s
method for multiple comparison is most appropriate (see chapter
2.7 of the text).
We see that Alcohol and Time both matter, but perhaps in
different ways. We consider both conditional comparisons. First
we run the emmeans() codemc.alc <- emmeans(fit, ~ Alcohol |
Time)## Warning in emm_basis.aovlist(object, ...): Some
predictors are correlated with the intercept - results are biased.

First note, that in all seven comparisons, the Moderate group is
never different than the Control group (this is true for all time,
smallest adjusted (p)-value is 0.0781). Thus, the profiles of
the Moderate group and the Control group are statistically the
same.
We can see that in the early time points, there was no difference
between the treatment groups receiving alcohol and those not
but as time progressed the “High” alcohol group had higher
reaction times than the control (starting at T3, it always
significant with adjusted (p)-value of 0.0380).
Next we compare the effects of time conditioning on the alcohol

We see that the Control group never deviates from the control
time point (T0). This should not be surprising given they
remained sober for the entire study. In both of the other
treatments we see the influence of Time (and thus alcohol
consumption) on reaction times.
Even though the profile of the Moderate group was not
significantly different than the Control group, they did
experience an increase in reaction times with the consumption
of alcohol (just not enough to deviate overall from the Control
group). We see that the High consumption did deviate from the
Control group sometime around time point T3 (90
minutes).Conclusions
We established above that the key finding is that those with a
11. high dosage of alcohol had a longer reaction time compared to
the the control group as time progressed. We also find that
those receiving a moderate amount of alcohol performed
similarly to the control group. We close by building a profile
plot to summarize the findings (remember, Age was not
important).
First we plot the profiles of the three alcohol treatments
summarizing over all ages.alcohol.summary <- alcohol.tall
%>%
group_by(Alcohol, Time) %>%
summarize(Mean=mean(Reaction),
SE= sd(Reaction)/sqrt(n()))
ggplot(alcohol.summary, aes(x=Time, y=Mean, color=Alcohol))
+
geom_errorbar(aes(ymin=Mean-SE, ymax=Mean+SE),
width=0.1, position=position_dodge(0.3)) +
geom_line(aes(group=Alcohol), position=position_dodge(0.3))
+
geom_point(position=position_dodge(0.3))
Note this plot is a bit misleading since we have plotted the
moderate group even though it is statistically similar to the
control group (note the SE bars overlap for all time points for
the moderate and contrl groups). To link the control and
moderate groups, we have to do a bit more data processing. In
the below code we recast the Alcohol variable to only two
groups.alcohol.summary2 <- alcohol.tall %>%
mutate(Alcohol = case_when(Alcohol=="High" ~ "Legally
Drunk",
TRUE ~ "Legally Sober")) %>% # `TRUE
~` is everything else
group_by(Alcohol, Time) %>%
summarize(Mean=mean(Reaction),
SE= sd(Reaction)/sqrt(n()))
The TRUE ~ "Legally Sober" line essentially tells R that in any
other case (TRUE is always True) to mark it as Legally Sober.
12. In the first line of the case_when statement we use the ==
notation to compare for equality.
Now we make an overall plot summarizing the findings of our
study. To demonstrate the level of sophistication we can include
in a plot, I do quite a bit with axes, labeling and color choices.
Note this is sort of thing covered in detail in STA404. Here we
demonstrate the functionality.ggplot(alcohol.summary2,
