Lab C HW SOCY 3115 Spring 20 Reviewing Labs A and B Use GSS2018V1.dta 1. There is a variable called ancestrs in the 2018 General Social Survey. This variable reflects the respondent’s answer to this question: Do you believe in supernatural powers of your deceased ancestors? a. Do a “tab ancestrs” and tab ancestrs, nolabel”. Cut-n-paste command and output here. b. What level-of-measurement is ancestrs? c. What percent of the sample believes “no, definitely not” when asked whether ancestors have supernatural powers? d. What percent of the sample believes that yes (either definitely or probably) ancestors have supernatural powers? 2. Make a new variable called believes that =1 if the person believes that yes (either definitely or probably) ancestors have supernatural powers; and =0 if the person believes that no (either definitely or probably) ancestors do not have supernatural powers. hint #1: use the generate and recode commands. hint #2: I did something just like this in Lab C when reviewing Stata from Unit 1 hint #3: you need to use the CODES for each of the values, not the labels. (remember, labels are the words, eg. “yes, definitely,” and CODES are the numbers that represent the words, e.g. “yes, definitely” is coded as a 1, so the number 1 should be used in creating the new variable. You can see the codes by typing, “tab ancestrs, nolabel” a. Show the commands you used to make the new variable. b. Run “tab believes” and cut-n-paste the command and output here. c. Using your new variable, what percent of people believe that at ancestors have supernatural powers? Is this the same as Q1d? 3. The variable called sei10 is an index of the socioeconomic status of the respondent. It’s a composite variable that reflects their education, income, and occupational status. a. Run “sum sei10” and cut-n-paste command and output here. b. What is the minimum value of sei10? What is the maximum? What is the mean? c. Make a new variable called sei75 that =1 if the respondent’s sei is at the 75th percentile or above; and =0 otherwise. I’m not giving you many hints for this. You should be able to find the cutoff for the 75th percentile using the sum command with the detail option. Then, use that value to make the new variable using the generate and recode method. Cut-n-paste the code you used here: d. Tabulate sei75. Cut-n—paste the command and output here. New Stuff for Lab C This week we learned how to manually construct confidence intervals. Now we will let Stata construct the Confidence Interval and we need only to interpret it! Use GSS2018_v1.dta 1. The variable numpartners is defined as the number of sex partners the respondent has had since age 18. Have Stata construct a 95% Confidence Interval that estimates the mean age of all American adults when they had their first child. Cut-n-paste command and output here: Interpret the 95% CI like we do when we construct CIs by hand. ...

In other words, do you think that a rational logic leads people to cooperate, knowing that we are all better off cooperating? Or does fear/insecurity, vanity, ambition, etc. lead actors to what could be argued an illogical path to conflict?

Section 1: Probability theory: Expected Value and Lotteries (ONE QUESTION TOTAL)
We discussed how the sample mean can be skewed by an extreme value. In a sample of 100 people from Texas, if a multi-millionaire oil baron is randomly chosen for the sample, the mean income in the sample would be skewed higher than the median.
The sample mean is sometimes referred to as the expected value, written E[X] for the expected value of X. In probability theory the expected value is the sum of all potential outcomes, weighted by the probability/chance of the occurrence. For example, assume you are close friends with the oil baron. You need money for school, and as your friend he will agrees to give you one of two cars he never drives, which you will immediately sell for cash. He will flip a coin to determine which one, giving you a 50/50 chance of each. Let’s say one car is worth $12,000 and the other car is worth $118,000. The expected value is written E[X] = 0.5 × $12,000 + 0.5 × $118,000 = $65,000. Notice that this is also the average of the two values.
Question 1: Consider a random lottery, where 2,250 people enter their name (only once per-person) and a machine selects one winner at random. Each player has an equal chance of selection and the winning prize is $425,000.
a. Absent any costs associated with winning or playing the lottery, what is the expected value of entering the lottery one time?
b. Assume the winner must pay a 20% tax on lottery winnings. Further, the dealer wants to charge an entry fee. Exactly 2,250 people believe in luck and will play if the expected value of the gamble is greater than or equal to zero. What is the maximum entry fee the dealer can charge? Will the dealer make a profit?
c. What is the fundamental difference between the typical Powerball or Megamillions lottery and the one we established in our example above? Use two sentences or less to explain.

WEEK 5 HOMEWORK 5
THIS WEEK INVOLVES READING NEW TABLES, THE t-TABLES. BUT, UNLIKE THE Z-TABLES WHERE YOU JUST NEEDED TO CALCULATE A Z-VALUE TO FIND THE PROBABILITY IN THE TABLE, WITH THE t-TABLE YOU NEED THE t-VALUE AND THE DEGREES OF FREEDOM, WHICH IS SIMPLY N – 1. THE t-VALUES DEPEND ON THE SIZE OF THE SAMPLE. THE t-DISTRIBUTION SHAPE CAN BE A “SKINNY” BELL CURVE, SYMETRICAL JUST LIKE THE NORMAL DISTRIBTION; BUT, AS YOU CAN SEE, THE LARGER THE SAMPLE SIZE THE MORE THE t-DISTRIBUTION SHAPE LOOKS LIKE THE NORMAL DISTRIBUTION SHAPE.
THE t-TABLES ARE IN OUR COURSE CONTENT > COURSE RESOURCES (NEAR THE BOTTOM OF CONTENT) > STATISTICAL RESOURCES. I SUGGEST YOU PRINT IT OUT AND REVIEW IT AS YOU READ THESE INSTRUCTIONS:
LET’S SAY YOU WANT TO BE 99% CONFIDENT (LEVEL OF CONFIDENCE) IN YOUR CONFIDENCE INTERVAL. THIS LEAVES A 1% CHANCE YOUR SAMPLE STATISTIC LIKE THE MEAN IS NOT IN THAT INTERVAL. KEEP IN MIND THAT THE CI HAS AN UPPER LIMIT AND A LOWER LIMIT SO THIS 1% COVERS BOTH ENDS. THIS MEANS THAT THE PROBABILITY THAT OUR RESULT IS IN ONE OR THE OTHER TAIL IS 1% / 2 = 0.5% (OR 0.005). THINK ABOUT IT. NOTE THAT IN THE TABLE THE 99% CI (BOTTOM LINE) EQUATES TO 0.005 ON THE TOP LINE. ALL WE NEED NOW IS THE DEGREES OF FREEDOM, WHICH IS N – 1, TO GET OUR CRITICAL t-VALUE FROM THE BODY OF THE TABLE. IN THIS EXAMPLE THE df IS 14, SO THE t-VALUE IS 2.977. THIS t-VALUE IS A CRITICAL VALUE LIKE A Z-VALUE.
THE t-TABLES ARE DIFFERENT FROM THE z-TABLES IN THAT WITH THE “t” WE SPECIFY THE PROBABILITY WE WANT AND THEN FIND THE CRITICAL t-VALUE. WITH THE NORMAL DISTRIBUTION, WE CALCULTE THE z-VALUE FIRST AND THEN COMPARE IT TO THE CRITICAL z-VALUE OF OUR DESIRED LEVEL OF SIGNIFICANCE (90%, 95%, OR 99%) TO SEE IF OUR CALCULATED z-VALUE IS FURTHER OUT IN EITHER TAIL, HENCE “UNUSUAL”.
THE NORMAL DISTRIBUTION CURVE IS ONE CURVE AND DOES NOT CHANGE WITH SAMPLE SIZE, HENCE WE CAN HAVE THE SAME CRITICAL z-VALUES FOR EVERY PROBLEM (99%, 95%, AND 90%). THE t-DISTRIBTUTION CURVE STARTS OUT A SKINNY BELL CURVE AND SLOWLY WIDENS AS THE SAMPLE SIZE (THE df) INCREASES. YOU CAN SEE FROM THE t-TABLE THAT WHEN THE df APPROACHES 1000, WE ARE VERY CLOSE TO THE NORMAL DISTRIBUTION’S BELL SHAPE. BUT, SINCE THE t-SHAPE CHANGES, THERE ARE DIFFERENT CRITICAL t-VALUES DEPENDING ON THE df (SAMPLE SIZES) INVOLVED.
HERE IS WHAT THE CONFIDENCE INTERVAL MEANS GRAPHICALLY: IN THIS SAMPLE PROBLEM WE WANTED A 95% CONFIDENCE LEVEL CONFIDENCE INTERVAL BASED ON A SAMPLE WITH A MEAN OF 3.26, A STD DEV OF 1.019 AND A SAMPLE SIZE OF 39 (df = 39-1 =38). THE CRITICAL t-VALUE FROM THE TABLE IS 2.023 (WE DON’T HAVE 39 df IN THE TABLE SO WE APPROXIMATED USING THE df FOR 39 AND 40). USE THE TABLE AND NOT SOFTWARE FOR THESE PROBLEMS. NOTE THAT THE 95% LEVEL MEANS 2.5% OF THE AREA UNDER THE t-CURVE IS IN EACH TAIL AS THE LIMITS.
NOW WE HAVE OUR t-VALUE = 2.023. REMEMBER WHEN WE STANDARDIZED OUR RAW DATA POINTS (THE X-VALUES) USING: Z = (X –MEAN)/STD DEV. IF WE WERE GIVEN T.

Part IProbability and Sampling Distributions1.Thinking about probability statements. Probability is measure of how likely an event is to occur. Match one of probabilities that follow with each statement of likelihood given (The probability is usually a more exact measure of likelihood than is the verbal statement.)Answer0 0.01 0.3 0.6 0.99 1(a) This event is impossible. It can never occur.(b) This event is certain. It will occur on every trial.(c) This event is very unlikely, but it will occur once in a while in a long sequence of trials.(d) This event will occur more often that not.2. Spill or Spell? Spell-checking software catches "nonword errors" that result in a string of letters that is not a word, as when "the" is typed as "the." When undergraduates are asked to write a 250-word essay (without spell-checking), the number X of nonword errors has the following distribution:Value of X01234Probability0.10.20.30.30.1(a) Check that this distribution satisfies the two requirements for a legitimate assignment of probabilities to individual outcomes.(b) Write the event "at least one nonword error" in term of X (for example, P(X >3)). What is the probability of this event?(c) Describe the event X ≤ 2 in words. What is its probability? 3. Discrete or continuous? For each exercise listed below, decide whether the random variable described is discrete or continuous and explains the sample space.(a) Choose a student in your class at random. Ask how much time that student spent studying during the past 24 hours.(b) In a test of a new package design, you drop a carton of a dozen eggs from a height of 1 foot and count the number of broken eggs.(c) A nutrition researcher feeds a new diet to a young male white rat. The response variable is the weight (in grams) that the rat gains in 8 weeks.4. Tossing Coins(a) The distribution of the count X of heads in a single coin toss will be as follows. Find the mean number of heads and the variance for a single coin toss.Number of Heads (Xi)01mean:Probability (Pi)0.50.5variance:(b) The distribution of the count X of heads in four tosses of a balanced coin was as follows but some missing probabilities.

Generating a sampling distribution. Let's illustrate the idea of a sampling distribution in the case of a very small sample from a very small .

Example of a one-sample Z-test
The previous lecture in Powerpoint explained the general procedure for conducting a hypothesis
test. Now let’s go through an example of a hypothesis test to see how it actually works.
Say you’ve developed a new drug that you think might influence people’s cognitive ability,
although you aren’t really sure what it will do. (Yes, this is a really bad study!) You give the
drug to a sample of N = 49 people and then test their IQ. Say their IQ turns out to be X = 106.
Based on decades of test development, we know that in the general U.S. population, the mean IQ
is = 100 with a standard deviation of = 15. So the research question that we want to address
is whether the people who take the “IQ Pill” will have IQ scores that are different from the
general population (suggesting that the pill had some effect), or whether they basically look the
same as everybody else in the country (suggesting that the pill didn’t do anything).
Let’s test this question by using the formal steps of hypothesis testing:
1.Generate H0 and HA
2.Select statistical procedure
3.Select
4.Calculate observed statistic for your data
5.Determine critical statistic
6.Compare (4) and (5)
7.If (4) exceeds (5), reject H0
8.Otherwise, fail to reject H0
1. Generate H0 and HA
So what are H0 and HA? We don’t know whether the drug will make people’s IQs get higher or
lower, so we need to use a 2-tailed or non-directional hypothesis test. Since the mean in the
general population is 100, we will test whether the mean in our test group is equal to 100.
H0: = 100 HA: 100
In this case, refers to the mean of the population that our treatment group represents. This is a
theoretical population of people who have taken our IQ pill. Obviously, this population doesn’t
exist in reality, because the only people who have ever taken our pill are the 49 people who were
in our study. But IN THEORY, a whole lot of other people could also take this drug, and IN
THEORY, they should respond to it in the same way that our 49 participants respond. So we are
making an inference from our 49 participants to that very large group of people who in theory
could also have taken this drug.
2.Select statistical procedure
At this point, I’m just going to tell you that the statistical procedure that you will use is
something called the Z-test. This is a test that is appropriate for testing whether one sample is
different from some specified value when the value of the population standard deviation () is
known. Over the next few days, we will be introduced to some other statistical procedures that
are appropriate for different kinds of situations than this, and you will need to choose which one
is the best to use.

researcher might choose one level compared to a.

Making Statistics Work For Us: Item Bias, Decision Making, and Data-Driven Si...
This talk is about a common problem of imposing a minimum sample size in a business context in order to make decisions. By using Bayesian approaches, we can drastically increase the speed to decision making.
This quote cited in the talk sum it up well:
"An ironic property about effect estimates with relatively large standard errors is that they are more likely to produce effect estimates that are larger in magnitude than effect estimates with relatively smaller standard errors.... There is a tendency sometimes towards downplaying a large standard error (which might increase the p-value of their estimate) by pointing out that, however, the magnitude of the estimate is quite large. In fact, this 'large effect' is likely a byproduct of this standard error.”

· What did you find that was really useful, or that challenged your thinking?
· What are you still mulling over?
· Was there anything that you may take back to your classroom?
· Is there anything you would like to have clarified?
Your Weekly Reflection will be graded on the following criteria for a total of 5 points:
· Reflection is written in a clear and concise manner, making meaningful connections to the investigations & objectives of the week.
· Reflection demonstrates the ability to push beyond the scope of the course, connecting to prior learning or experiences, questioning personal preconceptions or assumptions, and/or defining new modes of thinking.
BELOW ARE LESSON COVERED
· This week's investigations introduce and explore one of the most common distributions (one you may be familiar with): the Normal Distribution. In our explorations of the distribution and its associated curve, we will revisit the question of "What is typical?" and look at the likelihood (probability) that certain observations would occur in a given population with a variable that is normally distributed. We will apply our work with Normal Distributions to briefly explore some big concepts of inferential statistics, including the Central Limit Theorem and Hypothesis Testing. There are a lot of new ideas in this week’s work. This week is more exploratory in nature.
Goals:
· Explore the Empirical Rule
· Become familiar with the normal curve as a mathematical model, its applications and limitations
· Calculate z-scores & explain what they mean
· Use technology to calculate normal probabilities
· Determine the statistical significance of an observed difference in two means
· Use technology to perform a hypothesis test comparing means (z-test) and interpret its meaning
· Use technology to perform a hypothesis test comparing means (t-test) (optional)
· Gather data for Comparative Study Final Project.

1.What are the main issues facing Fargo and Town Manager Susan.docx
1.What are the main issues facing Fargo and Town Manager Susan Harlow?
Fargo and Town Manager Harlow are on a slippery slope to corruption. I think that Harlow is handling her position the correct way by trying to remain neutral and sticking to a code of ethics so the problem really comes down to the political actors in the town. It is good that Harlow declined the invite to the dinner party, and cracked down on employees playing politics at work, that is a step in the right direction to removing the possibility of political corruption.
2.What is the basis for your answer to question #1?
At the end of the article Harlow remembers another city manager saying “you never have more authority than the day you walk into your office” What I get from that, and what I think Harlow got from that is that when you come into a position as a public manager everyone is going to want something from you. Political actors are going to want political favors, quid pro quos, you have something that everyone else wants and they are going to try and get that from you.
3.What are your recommended solutions to the problems you identified?
I think the best thing to do would be to continue to try to remain neutral. It will always be impossible to please absolutely everybody so the best thing to do is try to avoid doing everything everyone asks and stick to some sort of code of ethics.
4.What points do you agree, disagree or want further discussion from your fellow classmates and why? (tell them not me)
I think the overarching theme of this article is that people are going to want things from the government. I agree with Harlow's steps to avoid political corruption in her administration by cracking down on political favors with the snow plows and referring to the ICMA code of ethics.

(277.283 KB)
For this assignment, you will practice analyzing how various rhetorical elements contribute to the overall meaning of a visual image--in this case, a photograph. To begin, click on the attached image.
By way of some context, this photo was taken in 2016 at a protest rally in Baton Rouge, Louisiana. The woman in the photo is named Ieshia Evans. The photographer is named Jonathan Bachman. Bachman's photo, which was first published by Reuters, was a finalist for a Pulitzer Prize in 2017. You can use this information to do more research on the image, if you like.
Now, review once again the Elements and Methods of Visual Rhetoric document and select from it
three
elements that you wish to discuss in relation to this photo. Please note that this is not a formal essay assignment, so do not treat it as such. For example, you do not need to create a formal introduction.
Begin by simply providing an
interpretive claim
--i.e., stating what you believe is the meaning or message of Bachman's photo. Ideally, this should be just
one
sentence (tho you can write two if necessary). After that, your document simply needs to contain
three paragraphs
, one for each rhetorical element you have selected. In each paragraph, you need to explain fully how the particular element contributes to the overall meaning or message of the image.
Note: Your assignment must be submitted as an attached .doc or .docx file. Name your file correctly, using your last name and brief description of assignment (e.g., Martinez, Photograph.docx).

Example of a one-sample Z-test The previous lecture in P.docx
Example of a one-sample Z-test
The previous lecture in Powerpoint explained the general procedure for conducting a hypothesis
test. Now let’s go through an example of a hypothesis test to see how it actually works.
Say you’ve developed a new drug that you think might influence people’s cognitive ability,
although you aren’t really sure what it will do. (Yes, this is a really bad study!) You give the
drug to a sample of N = 49 people and then test their IQ. Say their IQ turns out to be X = 106.
Based on decades of test development, we know that in the general U.S. population, the mean IQ
is = 100 with a standard deviation of = 15. So the research question that we want to address
is whether the people who take the “IQ Pill” will have IQ scores that are different from the
general population (suggesting that the pill had some effect), or whether they basically look the
same as everybody else in the country (suggesting that the pill didn’t do anything).
Let’s test this question by using the formal steps of hypothesis testing:
1.Generate H0 and HA
2.Select statistical procedure
3.Select
4.Calculate observed statistic for your data
5.Determine critical statistic
6.Compare (4) and (5)
7.If (4) exceeds (5), reject H0
8.Otherwise, fail to reject H0
1. Generate H0 and HA
So what are H0 and HA? We don’t know whether the drug will make people’s IQs get higher or
lower, so we need to use a 2-tailed or non-directional hypothesis test. Since the mean in the
general population is 100, we will test whether the mean in our test group is equal to 100.
H0: = 100 HA: 100
In this case, refers to the mean of the population that our treatment group represents. This is a
theoretical population of people who have taken our IQ pill. Obviously, this population doesn’t
exist in reality, because the only people who have ever taken our pill are the 49 people who were
in our study. But IN THEORY, a whole lot of other people could also take this drug, and IN
THEORY, they should respond to it in the same way that our 49 participants respond. So we are
making an inference from our 49 participants to that very large group of people who in theory
could also have taken this drug.
2.Select statistical procedure
At this point, I’m just going to tell you that the statistical procedure that you will use is
something called the Z-test. This is a test that is appropriate for testing whether one sample is
different from some specified value when the value of the population standard deviation () is
known. Over the next few days, we will be introduced to some other statistical procedures that
are appropriate for different kinds of situations than this, and you will need to choose which one

Example of a one-sample Z-test The previous lecture in P.docx
Example of a one-sample Z-test
The previous lecture in Powerpoint explained the general procedure for conducting a hypothesis
test. Now let’s go through an example of a hypothesis test to see how it actually works.
Say you’ve developed a new drug that you think might influence people’s cognitive ability,
although you aren’t really sure what it will do. (Yes, this is a really bad study!) You give the
drug to a sample of N = 49 people and then test their IQ. Say their IQ turns out to be X = 106.
Based on decades of test development, we know that in the general U.S. population, the mean IQ
is = 100 with a standard deviation of = 15. So the research question that we want to address
is whether the people who take the “IQ Pill” will have IQ scores that are different from the
general population (suggesting that the pill had some effect), or whether they basically look the
same as everybody else in the country (suggesting that the pill didn’t do anything).
Let’s test this question by using the formal steps of hypothesis testing:
1.Generate H0 and HA
2.Select statistical procedure
3.Select
4.Calculate observed statistic for your data
5.Determine critical statistic
6.Compare (4) and (5)
7.If (4) exceeds (5), reject H0
8.Otherwise, fail to reject H0
1. Generate H0 and HA
So what are H0 and HA? We don’t know whether the drug will make people’s IQs get higher or
lower, so we need to use a 2-tailed or non-directional hypothesis test. Since the mean in the
general population is 100, we will test whether the mean in our test group is equal to 100.
H0: = 100 HA: 100
In this case, refers to the mean of the population that our treatment group represents. This is a
theoretical population of people who have taken our IQ pill. Obviously, this population doesn’t
exist in reality, because the only people who have ever taken our pill are the 49 people who were
in our study. But IN THEORY, a whole lot of other people could also take this drug, and IN
THEORY, they should respond to it in the same way that our 49 participants respond. So we are
making an inference from our 49 participants to that very large group of people who in theory
could also have taken this drug.
2.Select statistical procedure
At this point, I’m just going to tell you that the statistical procedure that you will use is
something called the Z-test. This is a test that is appropriate for testing whether one sample is
different from some specified value when the value of the population standard deviation () is
known. Over the next few days, we will be introduced to some other statistical procedures that
are appropriate for different kinds of situations than this, and you will need to choose which one
is the best to use.

Making Statistics Work For Us: Item Bias, Decision Making, and Data-Driven Si...
This talk is about a common problem of imposing a minimum sample size in a business context in order to make decisions. By using Bayesian approaches, we can drastically increase the speed to decision making.
This quote cited in the talk sum it up well:
"An ironic property about effect estimates with relatively large standard errors is that they are more likely to produce effect estimates that are larger in magnitude than effect estimates with relatively smaller standard errors.... There is a tendency sometimes towards downplaying a large standard error (which might increase the p-value of their estimate) by pointing out that, however, the magnitude of the estimate is quite large. In fact, this 'large effect' is likely a byproduct of this standard error.”

· Focus on what you learned that made an impression, what may have surprised you, and what you found particularly beneficial and why. Specifically:
· What did you find that was really useful, or that challenged your thinking?
· What are you still mulling over?
· Was there anything that you may take back to your classroom?
· Is there anything you would like to have clarified?
Your Weekly Reflection will be graded on the following criteria for a total of 5 points:
· Reflection is written in a clear and concise manner, making meaningful connections to the investigations & objectives of the week.
· Reflection demonstrates the ability to push beyond the scope of the course, connecting to prior learning or experiences, questioning personal preconceptions or assumptions, and/or defining new modes of thinking.
BELOW ARE LESSON COVERED
· This week's investigations introduce and explore one of the most common distributions (one you may be familiar with): the Normal Distribution. In our explorations of the distribution and its associated curve, we will revisit the question of "What is typical?" and look at the likelihood (probability) that certain observations would occur in a given population with a variable that is normally distributed. We will apply our work with Normal Distributions to briefly explore some big concepts of inferential statistics, including the Central Limit Theorem and Hypothesis Testing. There are a lot of new ideas in this week’s work. This week is more exploratory in nature.
Goals:
· Explore the Empirical Rule
· Become familiar with the normal curve as a mathematical model, its applications and limitations
· Calculate z-scores & explain what they mean
· Use technology to calculate normal probabilities
· Determine the statistical significance of an observed difference in two means
· Use technology to perform a hypothesis test comparing means (z-test) and interpret its meaning
· Use technology to perform a hypothesis test comparing means (t-test) (optional)
· Gather data for Comparative Study Final Project.

DoW #5: The SAT & The ACT
Two Common Tests for college admission are the SAT (Scholastic Aptitude Test) and the ACT (American College Test). The scores for these tests are scaled so that they follow a normal distribution.
· The SAT reported that its scores were normally distributed with a mean μ=896 and a standard deviation σ=174
· The ACT reported that its scores were normally distributed with a mean μ=20.6 and a standard deviation σ=5.2.
We have two questions to consider for this week’s DoW:
2. A high school student Bobby takes both of these tests. On the SAT, he achieves a score of 1080. On the ACT, he achieves a score of 30. He cannot decide which score is the better one to send with his college applications.

1.What are the main issues facing Fargo and Town Manager Susan.docx
1.What are the main issues facing Fargo and Town Manager Susan Harlow?
Fargo and Town Manager Harlow are on a slippery slope to corruption. I think that Harlow is handling her position the correct way by trying to remain neutral and sticking to a code of ethics so the problem really comes down to the political actors in the town. It is good that Harlow declined the invite to the dinner party, and cracked down on employees playing politics at work, that is a step in the right direction to removing the possibility of political corruption.
2.What is the basis for your answer to question #1?
At the end of the article Harlow remembers another city manager saying “you never have more authority than the day you walk into your office” What I get from that, and what I think Harlow got from that is that when you come into a position as a public manager everyone is going to want something from you. Political actors are going to want political favors, quid pro quos, you have something that everyone else wants and they are going to try and get that from you.
3.What are your recommended solutions to the problems you identified?
I think the best thing to do would be to continue to try to remain neutral. It will always be impossible to please absolutely everybody so the best thing to do is try to avoid doing everything everyone asks and stick to some sort of code of ethics.
4.What points do you agree, disagree or want further discussion from your fellow classmates and why? (tell them not me)
I think the overarching theme of this article is that people are going to want things from the government. I agree with Harlow's steps to avoid political corruption in her administration by cracking down on political favors with the snow plows and referring to the ICMA code of ethics.

Writing: Practice in Reading a Photograph
Attached Files:
Bachman, Ieshia Evans, Baton Rouge (2016).jpg
(277.283 KB)
For this assignment, you will practice analyzing how various rhetorical elements contribute to the overall meaning of a visual image--in this case, a photograph. To begin, click on the attached image.
By way of some context, this photo was taken in 2016 at a protest rally in Baton Rouge, Louisiana. The woman in the photo is named Ieshia Evans. The photographer is named Jonathan Bachman. Bachman's photo, which was first published by Reuters, was a finalist for a Pulitzer Prize in 2017. You can use this information to do more research on the image, if you like.
Now, review once again the Elements and Methods of Visual Rhetoric document and select from it
three
elements that you wish to discuss in relation to this photo. Please note that this is not a formal essay assignment, so do not treat it as such. For example, you do not need to create a formal introduction.
Begin by simply providing an
interpretive claim
--i.e., stating what you believe is the meaning or message of Bachman's photo. Ideally, this should be just
one
sentence (tho you can write two if necessary). After that, your document simply needs to contain
three paragraphs
, one for each rhetorical element you have selected. In each paragraph, you need to explain fully how the particular element contributes to the overall meaning or message of the image.
Note: Your assignment must be submitted as an attached .doc or .docx file. Name your file correctly, using your last name and brief description of assignment (e.g., Martinez, Photograph.docx).

At the top of your post, please indicate SUPPORT or OPPOSE and then give your rationale. Then after you can view your classmates' posts, make your case to your fellow students.
2.There was a law that individuals who were indigent and who wished to litigate could apply to the courts for a total waiver of the normal filing fee. In the legislative session, however, a statute was enacted which limits the courts' authority to waive filing fees in lawsuits brought by prisoners against the state government.
Under this new law, a court has to require the prisoner to pay a filing fee "equal to 20 percent ... of the average monthly deposits made to the prisoner's [prison] account ... or the average balance in that account", whichever is greater (unless this calculation yields a figure larger than the normal filing fee).
A prisoner (who was indigent) wanted to appeal his case and was to be charged this fee. He filed suit claiming it was unconstitutional to charge this fee to prisoners.
Choose the side of the prisoner or the side of the state and tell why you would rule for the side you chose.
At the top of your post, please indicate SUPPORT PRISONER or OPPOSE PRISONER and then give your rationale. After you can view your classmates' posts, make your case to your fellow students.

The defendant argued the law did not apply to him because he did not use a computer to transmit the material. (ie He was the receiver, not the sender, of the child pornography.)
Do you believe that the sentence enhancement should be upheld? Give an economic analysis and rational for your choice.

This week, we’ve been introduced to the humanities and have taken some time to consider the role of the humanities in establishing socio-cultural values, including how the humanities differ from the sciences in terms of offering unique lenses on the world and our reality. Since one of the greatest rewards of being a human is engaging with different forms of art, we’ve taken some time this week to learn about what it means to identify and respond to a work of art. We’ve learned about the difference between abstract ideas and concrete images and concepts like structure and artistic form. To help you deepen your understanding of these foundational ideas, your Unit 1 assignment will consist of writing an essay addressing using the following criteria:
Essay Requirements:
• 1,000 words or roughly four double-spaced pages.
• Make use of at least three scholarly sources to support and develop your ideas. Our course text may serve as one of these three sources.
• Your essay should demonstrate a thorough understanding of the READ and ATTEND sections.
• Be sure to cite your sources using proper APA format (7th edition).
Essay Prompt:
• In this essay, you will consider the meaning of art and artistic form by responding to these questions:
o To what extent does Kevin Carter’s Pulitzer Prize-winning photograph (figure 2-5) have artistic form?
o Using what you’ve learned in Chapters 1, 2 and 14 explain if you consider Carter’s photograph a work of art? Be sure to point to specific qualities of the photograph to support/develop your response.
o How do you measure the intensity of your experience in response to Carter’s photograph? What does it make you see/feel/imagine and how does your response/reaction support Carter’s image as a work of art?

2024.06.01 Introducing a competency framework for languag learning materials ...
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

The Roman Empire A Historical Colossus.pdf
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Lab C HWSOCY 3115Spring 20Reviewing Labs A and BUse GSS2.docx
- 1. Lab C HW SOCY 3115 Spring 20 Reviewing Labs A and B Use GSS2018V1.dta 1. There is a variable called ancestrs in the 2018 General Social Survey. This variable reflects the respondent’s answer to this question: Do you believe in supernatural powers of your deceased ancestors? a. Do a “tab ancestrs” and tab ancestrs, nolabel”. Cut-n-paste command and output here. b. What level-of-measurement is ancestrs? c. What percent of the sample believes “no, definitely not” when asked whether ancestors have supernatural powers? d. What percent of the sample believes that yes (either definitely or probably) ancestors have supernatural powers? 2. Make a new variable called believes that =1 if the person believes that yes (either definitely or probably) ancestors have supernatural powers; and =0 if the person believes that no (either definitely or probably) ancestors do not have supernatural powers.
- 2. hint #1: use the generate and recode commands. hint #2: I did something just like this in Lab C when reviewing Stata from Unit 1 hint #3: you need to use the CODES for each of the values, not the labels. (remember, labels are the words, eg. “yes, definitely,” and CODES are the numbers that represent the words, e.g. “yes, definitely” is coded as a 1, so the number 1 should be used in creating the new variable. You can see the codes by typing, “tab ancestrs, nolabel” a. Show the commands you used to make the new variable. b. Run “tab believes” and cut-n-paste the command and output here. c. Using your new variable, what percent of people believe that at ancestors have supernatural powers? Is this the same as Q1d? 3. The variable called sei10 is an index of the socioeconomic status of the respondent. It’s a composite variable that reflects their education, income, and occupational status. a. Run “sum sei10” and cut-n-paste command and output here. b. What is the minimum value of sei10? What is the maximum? What is the mean? c. Make a new variable called sei75 that =1 if the respondent’s
- 3. sei is at the 75th percentile or above; and =0 otherwise. I’m not giving you many hints for this. You should be able to find the cutoff for the 75th percentile using the sum command with the detail option. Then, use that value to make the new variable using the generate and recode method. Cut-n-paste the code you used here: d. Tabulate sei75. Cut-n—paste the command and output here. New Stuff for Lab C This week we learned how to manually construct confidence intervals. Now we will let Stata construct the Confidence Interval and we need only to interpret it! Use GSS2018_v1.dta 1. The variable numpartners is defined as the number of sex partners the respondent has had since age 18. Have Stata construct a 95% Confidence Interval that estimates the mean age of all American adults when they had their first child. Cut- n-paste command and output here: Interpret the 95% CI like we do when we construct CIs by hand. 2. Using the same variable, construct a 99% Confidence Interval
- 4. that estates the mean age of all American adults when they had their first child. Cut-n-paste command and output here: Interpret the 99% CI like we do when we construct CIs by hand. 3. Which of the confidence intervals is wider – the 95% CI or the 99% CI? Why? (use what you know about the tradeoff between precision and confidence in your answer). 4. There is a variable in this file called presexok which =1 if the respondent believes that premarital sex is not wrong at all; and 0 otherwise. Construct a 95% Confidence Interval that estimates the population proportion (i.e. proportion of all US adults) who think premarital sex is not at all wrong. Cut-n-paste command and output here: a. Interpret the 95% CI like we do when we construct CIs by hand. b. Are you surprised by the estimated interval? Did you think this proportion would be higher, lower, or about this proportion? 5. Construct a 95% Confidence Interval that estimates the population proportion (i.e. proportion of all US adults) who
- 5. believe in life after death (probably or definitely). Hint: you will need to create a new variable that =1 if the person believes in life after death and 0 if they don’t. Use afterli to create this new binary variable then run the confidence interval. Cut-n- paste confidence interval here: a. Interpret the 95% CI like we do when we construct CIs by hand. b. Are you surprised by the estimated interval? Did you think this proportion would be higher, lower, or about this proportion and why?
