There should be multiple levels of entering the field of nursing based on the way people learn. Some people are more hands on then others and wouldn't want to be in school that long. A BSN would be financially more difficult and take up too much time for some people. The entry level should be an ADN because it is beneficial to people who can't stay in school long and they should also have plans to get a BSN if they want to progress in the nursing field. I think that the barriers are finance and time. The government or local hospitals could offer grants to students to further their education in nursing.
Do you agree or desagree with a statement above?

Subjects in the weapon condition were only slightly, but not significantly, less accurate than controls on the 20-item questionnaire. Weapon present subjects were correct on 45.8% of the items, while control (weapon absent) subjects were correct on 50.3% of the items, t(34) = 1.37, p > .05, one tailed.
What kind of study design is this (experimental or correlational)?
If experimental, what is the independent variable?
If experimental, what is the dependent variable?
What kind of statistical test did the author run, and how do you know the used this test?
What do you think the null and alternative hypotheses are in this study? You might have to guess, but make it an educated guesses

The past few years have seen an erosion of trust between the police and the general public. This is not the first time this has occurred in US history, but is a "current issue" that continues to make news. This is a good time to look at how we "measure police effectiveness".
After reading the article "The Good Cop: Knowing The Difference Between Lawful and Effective Policing and Rightful Policing- And Why It Matters"
a. Compare and contrast "Lawful/Effective Policing" and what the author calls "Rightful Policing".
b. Which do yo think is the best way to measure our law enforcement system in the US? Explain in detail.

Android Studio Code:
Provide a working android studio code i.e java and xml code for the activity below:
Develop an application that is capable to turn pages back and forth.
Detailed Instructions:
For the main activity, create a layout that represents a fictitious title and author. The activity should include a clickable button on the bottom right that allows you to go forward to the next activity. The next activity will simply be an image above simple text that can say anything.
Once in the next activity, below the text there should be two clickable buttons. On the left, a button that will take us back to our original title page. The right button does not need to go anywhere.

For this assignment, you will select an article from a print or online FAKE news source that addresses economic issues in an editorial fashion. Using the tools of analysis covered so far in this course, you should briefly (1-2 paragraphs) summarize the article, and then analyze and criticize the article. You must critique the article and not merely summarize it. Your paper should be well-written and should reflect your current knowledge of economic theory (as limited as it is). (Hint: A good starting point is to identify the assumptions of the author.)
Since this is a fake news assignment why do you think the article was believable? Are there clues in the article that the article might be FAKE news?
Please identify the article that was used

Ask a member of the Human Resources team (or the person who does the hiring) at your work what they see as the key characteristics of a successful manager. In the discussion thread, provide a summary, answering the following questions: What company do you work for and what is the role of the individual you interviewed? What are the key characteristics of a successful manager that your colleague described? What are your thoughts on your colleaguebs response? OR Find an article discussing the key characteristics of a successful manager. Post a link to the article in the discussion thread and provide a summary of the following: What is the role and background of the author of the article? What are the key characteristics of a successful manager detailed in the article? What are your thoughts on these characteristics?

An infinitely long solid insulating cylinder of radius a = 2.1 cm is positioned with its symmetry axis along the z-axis as shown. The cylinder is uniformly charged with a charge density ρ = 27μC/m3. Concentric with the cylinder is a cylindrical conducting shell of inner radius b = 14.9 cm, and outer radius c = 17.9 cm. The conducting shell has a linear charge density λ = -0.36μC/m.
1 What is Ey(R), the y-component of the electric field at point R, located a distance d = 46 cm from the origin along the y-axis as shown?
2 What is V(P) - V(R), the potential difference between points P and R? Point P is located at (x,y) = (46 cm, 46 cm).
3 What is V(c) - V(a), the potentital difference between the outer surface of the conductor and the outer surface of the insulator?
4 Defining the zero of potential to be along the z-axis (x = y = 0), what is the sign of the potential at the surface of the insulator?
5 The charge density of the insulating cylinder is now changed to a new value,ρ’ and it is found that the electric field at point P is now zero. What is the value of ρ’?
