Write a function named "replacement" that takes a string as a parameter and returns an identical string except with every instance of the character "w" replaced with the character "v"

My code:

function replacement(word){
var str=word;
var n=str.replace("w","v");
return n;
}

Syntax Error: function replacement incorrect on input

Suppose we are given an arbitrary digraph G = (V, E) that may or may not be a DAG. Modify the topological ordering algorithm so that given an input G, it outputs one of the two things:

a. A topological ordering thus establishing that G is a DAG.

b. A cycle in G thus establishing that it is not a DAG.

The runtime of your algorithm should be O(m+n) where m = |E| and n = |V|

Write a program that prompts the user for a file name, make sure the file exists and then reads through the file, counts the number of times each word appears and outputs the word count in a sorted order from high to low.

The program should:

• Display a message stating its goal
• Prompt the user to enter a file name
• Check that the file can be opened and if not ask the user to try again (hint: use the try/except structure)
• Count the number of times each word appears in the file, regardless if in lowercase or uppercase (hint: use dictionaries and the lower() function)
• Display the word count in order from high to low
• Bonus: if a few words have the same count, sort the display in an alphabetic order
• For example, for the attached file NYT2.txt, the top five words in the output should be

the - 7

in - 6

to - 5

and - 4

of - 4

File Name: NYT2.txt

Question 5

Which of the following statements is FALSE?

As a medical professional, we will often be tasked with presenting a diagnosis to a patient with no educational background or experience within the healthcare profession. In these cases, it is critical to convey this very important and pertinent information to the patient in a way in which they can fully understand the information, i.e., to put the information into laymen terms, as well as making certain the patient is comfortable in seeking additional support and community.

In addition, patients in the above scenario might also choose to seek out the help of a healthcare advocate (a medical professional appropriately trained within the medical field) to help the patient research, organize, understand and communicate and field questions with the physician. Patient healthcare advocates require that the information is conveyed and presented to them as if the physician and/or healthcare professional were speaking to a colleague, i.e., medical and technical terms.

Assume the role of a healthcare professional tasked with educating both the newly diagnosed patient (in laymen terms), as well as the patient’s healthcare advocate (medical and technical terms).  

Instructions:

v Choose one cranial nerve injury or disease OR one spinal nerve injury or disease to serve as the focus of the assignment.

v Complete research on the selected injury or disease.

v Create an educational pamphlet for the patient that includes the following information on the injury or disease in laymen terms:

o   Anatomy

o   Physiological processes/pathways

o   Risk factors

o   Signs and symptoms

o   When to call the primary care provider or seek emergency room attention

o   Current and potential treatments (to include existing clinical trials)

o   Prevention strategies and measures

o   Online and community resources for further information and support

v Create an educational pamphlet for the patient’s healthcare advocate that includes the following information on the injury or disease in medical and technical terms:

o   Anatomy

o   Physiological processes/pathways

o   Risk factors

o   Signs and symptoms

o   When to call the primary care provider or seek emergency room attention

o   Current and potential treatments (to include existing clinical trials)

o   Prevention strategies and measures

o   Online and community resources for further information and support

v Be creative with the design and writing of each piece to make the information engaging and understandable for the patient and medically and technically appropriate for the patient’s healthcare advocate.

v Please be certain to cite any relevant information from sources used within your materials (to include photos and diagrams) in APA format.

v Please review the rubric to ensure that your assignment meets criteria.

Activity 1: How far can a soccer player kick a soccer ball down field? Through the application of a linear function and a quadratic function and ignoring wind and air resistance one can describe the path of a soccer ball. These functions depend on two elements that are within the control of the player: velocity of the kick (v k ) and angle of the kick (?). A skilled high school soccer player can kick a soccer ball at speeds up to 50 to 60 mi/h, while a veteran professional soccer player can kick the soccer ball up to 80 mi/h. Vectors Gravity The vectors identified in the triangle describe the initial velocity of the soccer ball as the combination of a vertical and horizontal velocity. The constant g represents the acceleration of any object due to Earth’s gravitational pull. The value of g near Earth’s surface is about ?32 ft/s2 . v x = v k cos ? & v y = v k sin ?

Analysis Finds Geographic Overlap In Opioid Use And Trump Support In 2016

June 23, 20188:02 AM ET

Paul Chisholm, NPR

In 2016, Donald Trump captured 68 percent of the vote in West Virginia, a state hit hard by opioid overdoses.

The fact that rural, economically disadvantaged parts of the country broke heavily for the Republican candidate in the 2016 election is well known. But Medicare data indicate that voters in areas that went for Trump weren't just hurting economically — many of them were receiving prescriptions for opioid painkillers.

The findings were published Friday in the medical journal JAMA Network Open. Researchers found a geographic relationship between support for Trump and prescriptions for opioid painkillers.

It's easy to see similarities between the places hardest hit by the opioid epidemic and a map of Trump strongholds. "When we look at the two maps, there was a clear overlap between counties that had high opioid use ... and the vote for Donald Trump," says Dr. James S. Goodwin, chair of geriatrics at the University of Texas Medical Branch in Galveston and the study's lead author. "There were blogs from various people saying there was this overlap. But we had national data."

Goodwin and his team looked at data from Census Bureau, the 2016 election and Medicare Part D, a prescription drug program that serves the elderly and disabled.

To estimate the prevalence of opioid use by county, the researchers used the percentage of enrollees who had received prescriptions for a three-month or longer supply of opioids. Goodwin says that prescription opioid use is strongly correlated with illicit opioid use, which can be hard to quantify.

"There are very inexact ways of measuring illegal opioid use," Goodwin says. "All we can really measure with precision is legal opioid use."

Goodwin's team examined how a variety of factors could have influenced each county's rate of chronic opioid prescriptions. After correcting for demographic variables such as age and race, Goodwin found that support for Trump in the 2016 election closely tracked opioid prescriptions.

In counties with higher-than-average rates of chronic opioid prescriptions, 60 percent of the voters went for Trump. In the counties with lower-than-average rates, only 39 percent voted for Trump.

A lot of this disparity could be chalked up to social factors and economic woes. Rural, economically-depressed counties went strongly for Trump in the 2016 election. These are the same places where opioid use is prevalent. As a result, opioid use and support for Trump might not be directly related, but rather two symptoms of the same problem – a lack of economic opportunity.

To test this theory, Goodwin included other county-level factors in the analysis. These included factors such as unemployment rate, median income, how rural they are, education level, and religious service attendance, among others.

These socioeconomic variables accounted for about two-thirds of the link between voter support for Trump and opioid rates, the paper's authors write. However, socioeconomic factors didn't explain all of the correlation seen in the study.

"It very well may be that if you're in a county that is dissolving because of opioids, you're looking around and you're seeing ruin. That can lead to a sense of despair," Goodwin says. "You want something different. You want radical change."

For voters in communities hit hard by the opioid epidemic, the unconventional Trump candidacy may have been the change people were looking for, Goodwin says.

Dr. Nancy E. Morden, associate professor at the Dartmouth Institute for Health Policy and Clinical Practice, agrees. "People who reach for an opioid might also reach for ... near-term fixes," she says. "I think that Donald Trump's campaign was a promise for near-term relief."

Goodwin's study has limitations and can't establish that opioid use was a definitive factor in how people voted.

"With that kind of study design, you have to be cautious in terms of drawing any causal conclusions," cautions Elene Kennedy-Hendricks, an assistant scientist in the Department of Health Policy and Management at the Johns Hopkins Bloomberg School of Public Health. "The directionality is complicated."

Goodwin acknowledges that the study has shortcomings.

"We were not implying causality, that the Trump vote caused opioids or that opioids caused the Trump vote," he cautions. "We're talking about associations."

Still, the study serves as an interesting example highlighting the links between economic opportunity, social issues and political behavior.

"The types of discussions around what drove the '16 election, and the forces that were behind that, should also be included when people are talking about the opioid epidemic," Goodwin says.

How and why do big cities attract big companies?

After reading "New Geography of Jobs" Forces of Attraction, it is very interesting as to why big cities like New York, Boston, San Francisco attract so many big companies to set their bases there. I share the confusion with the author, most companies in big cities have to pay higher wages to their employees because the expenditures for living is higher. It's not like you're going to get any information about your competitors if you set right beside them. Maybe there is a magical reason as to why these places attract big companies.
