More instructions for the lab write-up: 1) You are not obligated to use the 'diary' function. It was presented only for you convenience. You should be copying and pasting your code, plots, and results into some sort of "Word" type editor that will allow you to import graphs and such. Make sure you always include the commands to generate what is been asked and include the outputs (from command window and plots), unless the problem says to suppress it. 2) Edit this document: there should be no code or MATLAB commands that do not pertain to the exercises you are presenting in your final submission. For each exercise, only the relevant code that performs the task should be included. Do not include error messages. So once you have determined either the command line instructions or the appropriate script file that will perform the task you are given for the exercise, you should only include that and the associated output. Copy/paste these into your final submission document followed by the output (including plots) that these MATLAB instructions generate. 3) All code, output and plots for an exercise are to be grouped together. Do not put them in appendix, at the end of the writeup, etc. In particular, put any mfiles you write BEFORE you first call them. Each exercise, as well as the part of the exercises, is to be clearly demarked. Do not blend them all together into some sort of composition style paper, complimentary to this: do NOT double space. You can have spacing that makes your lab report look nice, but do not double space sections of text as you would in a literature paper. 4) You can suppress much of the MATLAB output. If you need to create a vector, "x = 0:0.1:10" for example, for use, there is no need to include this as output in your writeup. Just make sure you include whatever result you are asked to show. Plots also do not have to be a full, or even half page. They just have to be large enough that the relevant structure can be seen. 5) Before you put down any code, plots, etc. answer whatever questions that the exercise asks first. You will follow this with the results of your work that support your answer. SAMPLE QUESTION: Exercise 1: Consider the function f (x,C)= sin(C x) Cx (a) Create a vector x with 100 elements from -3*pi to 3*pi. Write f as an inline or anonymous function and generate the vectors y1 = f(x,C1), y2 = f(x,C2) and y3 = f(x,C3), where C1 = 1, C2 = 2 and C3 = 3. Make sure you suppress the output of x and y's vectors. Plot the function f (for the three C's above), name the axis, give a title to the plot and include a legend to identify the plots. Add a grid to the plot.

Overview The US is currently undergoing an energy boom largely because of the development of the greatly expanded use of a well technique developed over 40 years ago - hydraulic fracking. It can be used for both oil and natural gas wells.. The technique allows previously unrecoverable oil and gas in old, played out wells to be accessed and increases the efficiency of recovery in new wells significantly. The current level of both recovery and new well drilling is dramatically higher than it has been for decades. The dramatic increase in well activity, some of which has been near towns and places no one thought drilling would ever occur. It has brought a great deal of attention to the technique and associated effects on everything from ground water and air pollution, to biodiversity disruption and earthquakes. One important fact to weave into your opinion about fracking pro or con is that all of the sub-surface mineral rights in the US are owned by someone (a private individual, a business, or the state or federal government) but surface and mineral rights can be separated, i.e. sold. Originally, mineral rights were sold along with the land and then companies or individuals could decide if they wanted to keep or sell the mineral rights. Before mineral rights were so valuable, many people opted to sell their mineral rights to oil & gas companies. It never occurred to many people that someone would actually be drilling on their property or their neighbors. Oil and gas companies have a legal right to exercise their ownership options and if you are going to say "no" to them, then you owe them for what you are not letting them have, i.e. the money that would be produced if they were allowed to drill. This is not a trivial issue. Instructions This week’s discussion focuses on the pros and cons of hydraulic fracking and asks for your SCIENCE informed opinion on whether the economics and political fossil fuel issues justify the negative tradeoffs. Address each of the following in your discussion: How is fracking done and why are companies doing this action versus traditional drilling? Are the environmental issues with fracking worse than conventional drilling? Why or why not? Why are people along the Front Range and in other states where fracking is widespread, so upset about it now even though fracking has been occurring for a long time? *In your initial post, please provide 3-4 references in APA format with in-text citations. .

Overview The United Nations (UN) has hired you as a consultant, and your task is to assess the impact that global warming is expected to have on population growth and the ability of societies in the developing world to ensure the adequate security of their food supplies. Case Assessment As the world’s population nears 10 billion by 2050, the effects of global warming are stripping some natural resources from the environment. As they diminish in number, developing countries will face mounting obstacles to improving the livelihoods of their citizens and stabilizing their access to enough food. The reason these governments are struggling even now is that our climate influences their economic health and the consequent diminishing living standards of their peoples. Climate changes are responsible for the current loss of biodiversity as well as the physical access to some critical farming regions. As such, these changes in global weather patterns diminish agricultural output and the distribution of food to local and international markets. These difficulties will become even more significant for these countries as the Earth’s climate changes for the worse. Temperatures are already increasing incrementally, and polar ice caps are melting, so the salient question is: what does this suggest for developing societies? The issue before the developing world is not its lack of food, but rather how to gain access to food. Simply put, changes in our climate are affecting the global food chain, and hence, the living standards of entire populations. Added to this is the fact that food is not getting to where it is needed in time to prevent hunger or starvation. In many developing countries, shortages are due to governments’ control over distribution networks rather than an insufficient supply of food itself. In effect, these governments are weaponizing food by favoring certain ethnic or religious groups over others. When added to dramatic climate changes that we are experiencing even now, the future for billions of poor people looks increasingly dim. Instructions You are to write a minimum of a 5 page persuasive paper for the UN that addresses the following questions about the relationship between atmospheric weather patterns and food security in the developing world: Climate change and global warming are often used interchangeably, but they are not the same phenomenon. What are the differences between the two concepts and what leads to the confusion between them? In 1900, the average global temperature was about 13.7° Celsius (56.7° Fahrenheit) (Osborn, 2021), but as of 2020, the temperature has risen another 1.2°C to 14.9°C (58.9°F). According to the Earth and climate science community, if the Earth’s surface temperature rises another 2°C (3.6°F), we will suffer catastrophic weather patterns that, among other things, will raise sea levels, cause widespread droughts and wildfires, result in plant, insect, and animal extinctions, and reduce agricultura.

Overview This project will allow you to write a program to get more practice with object-oriented ideas that we explored in the previous project, as well as some practice with more advanced ideas such as inheritance and the use of interfaces. Ipods and other MP3 players organize a user's music selection into groups known as playlists. These are data structures that provide a collection of songs and an ordering for how those songs will be played. For this assignment you will be writing a set of PlayList classes that could be used for a program that organizes music for a user. These classes will be written to implement a particular PlayList interface so that they can be easily exchange in and out as the program requires. In addition, you will also be using the SimpleTrack class you wrote for the closed lab on Interfaces - if you did not finish this class before the end of lab, you will need to finish it before starting on this project. Objectives Practice with programming fundamentals Review of various Java fundamentals (branching, loops, variables, methods, etc.) Review of Java File I/O concepts Practice with Java ArrayList concepts Practice with object-oriented programming and design Practice with Java interfaces Project Description The SimplePlaylist Class Once you have coded and tested your SimpleTrack class, you will need to write a SimplePlaylist class that implements the Playist interface given in the project folder. The SimplePlayList class stores music tracks in order - the first track added to the play list should be the first one removed from the play list. You should recognize this data structure as a queue (or a first-in, first-out queue ). You do not need to implement the equals, hashCode and toString methods for this class but if you choose to do so make sure you document your implementations properly! The PlayList Management Program Once you have written and tested a SimpleTrack class and a SimplePlaylist class, it is time to use them to write a program to manage playlists. This program will simulate the playing of songs from a play list. For the SimplePlaylist, the songs are removed from the playlist as they are played, so you know that you're at the end of the list when your list is empty. This program should be implemented in the file MusicPlayerSimulator.java. Note that we are not defining ANY of the methods you are using for this program - the design is all up to you. You must, however, practice good programming style - make sure you are breaking the program up into smaller methods and aren't just trying to solve everything with one monolithic main method. If you have fewer than 5 methods for this program you are probably trying to fit too much into a single method. Here is a sample transcript of the output of this program: Enter database filename: input.txt Currently playing: 'Elvis Presley / Blue Suede Shoes / Elvis Presley: Legacy Edition' Next track to play: 'The Beatles / Wit.

Overview This week, we begin our examination of contemporary responses to youths’ illegal behaviors. The goal for this week is to assess pre-adjudication responses to youths’ illegal behavior. Primarily, our focus will be on nonformal responses or diversion. As a prelude to this discussion, we will consider the “school to prison pipeline” as it provides a good way to understand the need for diversion in juvenile justice. Objectives Upon completion of this week’s lesson, you should be able to: Define what is meant by the “school to prison pipeline.” Explain how the political economy contributes to the school to prison pipeline. Explain how trends in education, policing, and juvenile justice contribute to the school to prison pipeline Describe juvenile arrest trends and trends in the willingness of police to refer youths to juvenile court. Define radical nonintervention or true diversion and assess the role in can play in juvenile justice. Explain the rationale for diversion and its value in juvenile justice. Describe diversion programs that appear to be effective and programs that are not effective Assess arguments that are made in support of diversion. Assess the potential problems that should be addressed when developing or operating diversion programs Tasks View Video Lecture (Part 1 and Part 2 below) on the School to Prison Pipeline.

Overview Progress monitoring is a type of formative assessment in which student learning is evaluated on a regular basis to provide useful feedback about performance to both students and teachers. Though there are a number of methods for monitoring a student’s progress, the most widely used is general outcome measurement, sometimes referred to as curriculum-based measurement (CBM). Progress monitoring consists of the frequent administration (e.g., once per month, every two weeks) of brief probes or tests, which include sample items from every skill taught across the academic year. After each probe is scored, the teacher or student plots the score on an individual CBM graph. The teacher can then use this data to determine a student’s: • Rate of growth — Average growth of a student’s mathematics skills over a period of time • Performance level — An indication of a student’s current mathematics skills, often denoted by a score on a test or probe. You will determine the rate of growth for the two students listed on page 3 using the data provided. .

Overview Imagine you have been hired as a consultant for the United Nations. You have been asked to write an analysis on how global population growth has caused the following problem and how it affects TURKEY A growing global population that consumes natural resources is partially to blame for the release of greenhouse gases since human consumption patterns lead to deforestation, soil erosion, and farming (overturned dirt releases CO2). However, the critical issue is the burning of fossil fuels (hydrocarbons) such as coal oil and natural gas to produce energy that is used for things like electricity production, and vehicle, heating, and cooking fuels. Instructions Content The U.N. has asked that your paper contain three sections. It has asked that each section be one page (or approximately 300 words) in length and answer specific questions, identified in the outline below. It also asks that you use examples from Turkey when answering the questions. Introduction Provide an introduction of half a page minimum that addresses points points 1–5 below: Explain the problem the U.N. has asked you to address in your own words. Identify the three sections your paper will cover. Identify the developing country (TURKEY) you will consider. Telly the U.N. which causes of greenhouse gases you will explore. Provide a one-sentence statement of your solutions at the end of your introduction paragraph. Section I. Background What are greenhouse gases? How do greenhouse gases contribute to global warming? Section II. How Emissions Causes Problems for the Developing World Which countries produce the most greenhouse gases? What are the economic challenges of these emissions in Turkey? What are the security challenges of these emissions in Turkey? What are the political challenges of these emissions in Turkey? Section III. Causes and Solution s of Greenhouse Gases Name two causes of greenhouse gases. What are potential solutions to address each of the causes you identified? What is the relationship between population control and greenhouse gases? Conclusion Provide a conclusion of half a page minimum that includes a summary of your findings that the United Nations can use to inform future policy decisions. Success Tips In answering each question, use examples from Turkey to illustrate your points. The U.N. needs facts and objective analysis on which to base future policy decisions. Avoid personal opinion and make sure your answers are based on information you find through research.

Overview Develop a 4–6-page position about a specific health care issue as it relates to a target vulnerable population. Include an analysis of existing evidence and position papers to help support your position. Your analysis should also present and respond to one or more opposing viewpoints. Note : Each assessment in this course builds on the work you completed in the previous assessment. Therefore, you must complete the assessments in this course in the order in which they are presented. Position papers are a method to evaluate the most current evidence and policies related to health care issues. They offer a way for researchers to explore the views of any number of organizations around a topic. This can help you to develop your own position and approach to care around a topic or issue. This assessment will focus on analyzing position papers about an issue related to addiction, chronicity, emotional and mental health, genetics and genomics, or immunity. Many of these topics are quickly evolving as technology advances, or as we attempt to push past stigmas. For example, technology advances and DNA sequencing provide comprehensive information to allow treatment to become more targeted and effective for the individual. However as a result, nurses must be able to understand and teach patients about the impact of this information. With this great power comes concerns that patient conditions are protected in an ethical and compassionate manner. By successfully completing this assessment, you will demonstrate your proficiency in the following course competencies and assessment criteria: Competency 1: Design evidence-based advanced nursing care for achieving high-quality population outcomes. Evaluate the evidence and positions of others that could support a team's approach to improving the quality and outcomes of care for a specific issue in a target population. Evaluate the evidence and positions of others that are contrary to a team's approach to improving the quality and outcomes of care for a specific issue in a target population. Competency 2: Evaluate the efficiency and effectiveness of interprofessional interventions in achieving desired population health outcomes. Explain the role of the interprofessional team in facilitating improvements for a specific issue in a target population. Competency 3: Analyze population health outcomes in terms of their implications for health policy advocacy. Explain a position with regard to health outcomes for a specific issue in a target population. Competency 4: Communicate effectively with diverse audiences, in an appropriate form and style, consistent with organizational, professional, and scholarly standards. Communicate an initial viewpoint regarding a specific issue in a target population and a synthesis of existing positions in a logically structured and concise manner, writing content clearly with correct use of grammar, punctuation, and spelling.

Overall Scenario Always Fresh Foods Inc. is a food distributor with a central headquarters and main warehouse in Colorado, as well as two regional warehouses in Nevada and Virginia. The company runs Microsoft Windows 2019 on its servers and Microsoft Windows 10 on its workstations. There are 2 database servers, 4 application servers, 2 web servers, and 25 workstation computers in the headquarters offices and main warehouse. The network uses workgroups, and users are created locally on each computer. Employees from the regional warehouses connect to the Colorado network via a virtual private network (VPN) connection. Due to a recent security breach, Always Fresh wants to increase the overall security of its network and systems. They have chosen to use a solid multilayered defense to reduce the likelihood that an attacker will successfully compromise the company’s information security. Multiple layers of defense throughout the IT infrastructure makes the process of compromising any protected resource or data more difficult than any single security control. In this way, Always Fresh protects its business by protecting its information. Scenario 1 Assume you are an entry-level security administrator working for Always Fresh. You have been asked to evaluate the option of adding Active Directory to the company’s network. Tasks Create a summary report to management that answers the following questions to satisfy the key points of interest regarding the addition of Active Directory to the network: 1. System administrators currently create users on each computer where users need access. In Active Directory, where will system administrators create users? 2. How will the procedures for making changes to the user accounts, such as password changes, be different in Active Directory? 3. What action should administrators take for the existing workgroup user accounts after converting to Active Directory? 4. How will the administrators resolve differences between user accounts defined on different computers? In other words, if user accounts have different settings on different computers, how will Active Directory address that issue? (Hint: Consider security identifiers [SIDs].) .

The nurse has very little time to get detailed patient information. He or she must make a quick assessment and take action based on hospital protocol. The organized chaos of the emergency room presents unique ethical challenge, which is why nurses are required to have knowledge of ethical concepts and principles.

Overall feedback: You addressed most all of the assignment requirements. The assignment had several requirements including, but not limited to: an introduction, 3 questions, conclusion, and at least 2 scholarly references to support your claims. You did include an introduction. However, the introduction should briefly identify the key areas/sections to be covered in the paper. This helps the reader navigate through the organization of both your paper and thought process. You did address the question requirements. The assignment required at least 2 scholarly peer reviewed journal articles. Although you included several references, I only saw one scholarly peer reviewed journal article. Moving forward. Be sure to carefully review the instructions before and after you complete your final draft to ensure all requirements have been met. Second, always include an introduction which briefly describes what areas will be covered. Finally, make sure that you include the required number of scholarly peer reviewed journal articles to support your claims. If you have questions, please contact me. be sure to fully address the question with terminology and concepts from the book to apply to the case. This demonstrates proficiency at the required tasks. For example, question 2 asked: Question #2: Discuss your plans for developing formal job descriptions for the employees at the second shop For this question, I was looking for your approach in terms of methods discussed in the text (interviews, observations, questionnaires, etc.) and application to the case study to show application of the concepts/theories. As far as the scholarly peer reviewed journal articles, this is an essential part of supporting your claims at the graduate level of writing. The assignment required 2 scholarly peer reviewed journal articles. I only saw one? The purpose of this requirement is to ensure that you are supporting your claims with contemporary research within the management/business discipline. Second, this also gives credit to the author's ideas. While I do not point out every error or missing item on your paper, I focus on those areas/content that are required and can be improved. Moving forward, be sure to fully address each question with terminology from the text/material, as well as provide examples to demonstrate the ability to apply the concepts to the case study.

Over the years, the style and practice of leadership within law enforcement agencies has gradually changed. In the past, leadership was primarily relegated to one individual within the department. However, there has been a transformation in leadership theory resulting in a more dynamic, multifaceted nature of teamwork, inclusion, and dispersed leadership. More and more, police chiefs are being encouraged to move toward a more participatory leadership style of management, one that encourages collaboration and cooperation in the decision-making process. Based on your readings in the text and credible Internet research, respond to the following: What does the term shared leadership mean? What advantages or disadvantages do you see in this leadership approach? What direction should law enforcement leaders take for the future, related to leadership styles? What does the term visionary leadership mean? 2-3 pages .
