Business Law Short Essay

/in /by

 Respond fully to the following fact pattern and the questions that follow. Identify and discuss the relevant legal and ethical issues presented. You may want to do some outside reading/ research to help you in formulating your answer. Be sure to cite your sources as needed. Your response should be approximately 750 words (2.5 to 3 pages in length). Please use Times New Roman 12 pt. font and standard margins (this makes it easier).  

                                                           Fact Pattern 

In the Clean Air Act as amended, Congress allowed California, which has serious problems with air quality, to adopt its own standards for emissions from cars and trucks, subject to the approval of the Environmental Protection Agency (EPA) according to certain standards. The Act also allowed other states to adopt California’s standards after EPA approval. 

In 2004, California adopted emissions standards for all new passenger vehicles and lightduty trucks sold in California beginning in 2009. The standards imposed decreasing limits on emissions of carbon dioxide and other greenhouse gases (GHG) through 2016. 

While EPA approval was pending, other states adopted the California standards. A group of industry associations, automakers, and new car dealerships filed suit to block state adoption of the standards (including California).

 (a) Under the Environmental Policy and Conservation Act (EPCA), a designated federal agency sets fuel economy standards for new cars. The plaintiffs argued, among other things, that the EPCA, which explicitly prohibits states from adopting separate fuel economy standards, preempts states from adopting their own emission standards. Is the plaintiffs’ argument valid? Discuss.

 (b) Do the state emissions rules impose on the efforts of the federal government to address global warming internationally? Who should regulate GHGs, the states or the federal government? Both? Neither? Discuss.

 (c) The plaintiffs also argued that they would go bankrupt if they were forced to adhere to a different GHG standard for each state. Should they be granted relief on this basis? Does history support their claim? Discuss.

 This is a Business Law course! I am not particularly interested in reading treatises on libertarianism or environmentalism – I want you to think critically about the trade-offs between business and the environment, and comment on the legal and ethical issues that are presented above.

TOPIC C – posted Thursday#1) You can readily understand why forecasting net cash flows is a necessary skill in financial management. SO, how do we forecast cash collections from customers? Sales RevenuesNovember $        50,000actualDecember $        75,000actualJanuary $        20,000actualFebruary $        15,000ForecastIf the credit manager tells us cash is collected from credit sales, as follows:25% is collected in the month of sale50% from the prior month’s sales20% from two months ago3% from three months agoa) Is it okay that the total collected is only 98% of sales? How do you explain this?b) How much cash will be collected in February?#2) Some wrap-up questionsa) How is a single payment different from an annuity?b) What are some of the ways that time value of money concepts are used in the finance profession?c) What is the difference between discounting and compounding? Which term applies to future value calculations? Which one applies to present values?TOPIC B – posted TuesdayThere are many uses of the calculations we are discussing. For example, the Present Value of the cash flow from a bond payable determines its current cost to an investor (or borrower).A bond has two sources of cash, 1) the interest payments, paid at the stated rate (%) usually semi-annually and 2) the single-sum paid upon maturity to the investor/lender. Each of these is a separate variable in the =PV function. The interest rate input into the PV function is called the yield-to-maturityand is often different from the stated interest rate used to calculate the bond periodic interest payments.Use this template PVFunc.png for the Excel function  =pv(rate,nper,pmt,fv) to calculate the solution to these exercises:a) What is the present value of bond payable when the current market interest rate is 5% and whose semi-annual payment is based on an annual coupon rate of 4% over the next 20 years? The Future Value is $100,000.b) Alltech Corporation on January 1, 2017, issues $100,000 of 5% bonds due in 5 years with interest payable annually at year-end.The current market rate of interest for bonds of similar risk is 6%. What will the buyers pay for this bond (the PV) at issue?c) Recently, the vice president of operations of the company has requested construction of a new plant to meet the increasing demand issuing $3,000,000 of 11% term corporate bonds on March 1, 2017, due on March 1, 2032, with interest payable each March 1 and September 1. At the time of issuance, the market interest rate for similar financial instruments is 10%. Determine the selling price of the bonds.TOPIC A – posted SundayThis week can be quite easy if we use the Excel functions described in the week’s lesson. FIN515_wk2_TVM2A_Recording_edited (1).mp4The idea is that you can calculate in today’s dollars, the value of say a series of loan payments. Finance managers may use this present value (PV) to determine if refinancing is justified.(A) For example, what is the PV of a $100,000, 30 year mortgage, with a 4% stated interest rate?

  1. Assuming the current market interest rate is 5% 
  2. Assuming the current market interest rate is 4%
  3. Assuming the current market interest rate is 3%

Here’s a snapshot of the Excel function that solves the first question (5%) (B) SO why is an investment paying 4% sold at a discount, if alternative investments pay 5%?There is also a tutorial video in this week’s lesson about using Excel for TVM calculations. If you are comfortable with these functions, try some of these exercises:(C) Please respond to a handful of these preliminary questions1) What is the difference between future value and present value? What data do you need to do a future value or present value calculation?  What are various ways to calculate the time value of money in addition to using the future value and present value formulas? 2)  A given amount of money today is worth (more or less) than that same amount of money a year from now. Other things being equal, a higher interest rate on a car loan will result in (higher or lower) payment?  Other things being equal, a longer term on a car loan will result in (higher or lower) payment?3) Which of the following variables, whether stated or implied, are always present in an =PV or =FV calculation:   PV, FV, i, n, or PMT?4) Rita is wondering how much of a car loan she can get if the interest rate is 3% and she is willing to pay $200 per month for 5 years. She is looking for the _____ function. Laura wants to contribute $5,000 each year to her 401(k). The investments in the 401(k) are expected to earn a rate of 10% per year. She is wondering how much money she will have when she retires in 25 years? She is looking for the _____ function.5) Michelle is 45 years old. She plans to retire when she is 65 years old. She figures she will have $1,000,000 in her 401(k) when she retires. The 401(k) will be invested in a fund that has a guaranteed rate of 5%. After retirement, she plans on living another 20 years. She wants to leave an estate of $200,000 to her grandchildren. She wonders how much she can withdraw from her 401(k) per year after retirement and accomplish her goal of an inheritance for her grandchildren?

System Programming

/in /by

BACKGROUND: A shell provides a command-line interface for users. It interprets user commands and executes them. Some shells provide simple scripting terms, such as if or while, and allow users to make a program that facilitates their computing environment. Under the hood, a shell is just another user program as you know from Minor2 assignment. The file /bin/bash is an executable program file for the bash shell. The only thing special about your login shell is that it is listed in your login record so that /bin/login (i.e., the program that prompts you for your password) knows what program to start when you log in. If you run “cat /etc/passwd”, you will see the login records of the machine.

PROGRAM DESCRIPTION

GROUP COLLABORATIVE PORTION: In this assignment, you will implement the shell “engine” as the group component, where all members are responsible for the following functionality.

A Command-Line Interpreter, or Shell

Your shell should read the line from standard input (i.e., interactive mode) or a file (i.e., batch mode), parse the line with command and arguments, execute the command with arguments, and then prompt for more input (i.e., the shell prompt) when it has finished. This is what Minor 2 program should do with addition of batch processing which means just reading a batch line by line and calling the same interpretation logic.

  1. Batch Mode

In batch mode, your shell is started by specifying a batch file on its command line. The batch file contains the list of commands that should be executed. In batch mode, you should not display a prompt, but you should echo each line you read from the batch file back to the user before executing it. After a batch is finished the shell will exit.

  1. Interactive Mode

No parameters specified on command line when the shell is started. In this mode, you will display a prompt (any string of your choice) and the user of the shell will type in a command at the prompt.

You will need to use the fork() and exec() family of system calls. You may not use the system() system call as it simply invokes the system’s /bin/bash shell to do all of the work. You may assume that arguments are separated by whitespace. You do not have to deal with special characters such as ‘, “, , etc. You may assume that the command-line a user types is no longer than 512 bytes (including the ‘n’), but you should not assume that there is any restriction on the number of arguments to a given command.

INDIVIDUAL PORTIONS

Build-in Commands: Every shell needs to support a number of built-in commands, which are functions in the shell itself, not external programs. Shells directly make system calls to execute built-in commands, instead of forking a child process to handle them.

In this assignment, each member of the group will implement one of the following section and commit in GitLab the code that supports those commands:

  1. Add a new built-in alias command that allows you to define a shortcut for commands by essentially defining a new command that substitutes a given string for some command, perhaps with various flags/options. The syntax is as follows: alias alias_name=’command’. For example, you can define an alias with alias ll=’ls –al’, so that the user can then enter ll at the prompt to execute the ls -al command. Specifying alias with no arguments should display a list of all existing aliases. You may remove a single alias with the command alias -r alias_name or all defined aliases with alias -c.
  2. Add a new built-in exit command that exits from your shell with the exit() system call. Also add support for signal handling and terminal control (Ctrl-C, Ctrl-Z). You do not want those signals to terminate your shell. Instead you need to handle them and terminate processes that your shell started if any. Be aware that forked processes will inherit the signal handlers of the original process.
  3. Add a new built-in path command that allows users to show the current pathname list. The initial value of path within your shell will be the pathname list contained in the PATH environment variable. path + ./dir appends the ./dir to the path variable. You may assume that only one pathname is added at a time. You will need to add it to the “real” PATH environment variable for executables in the path to work correctly. path – ./dir removes the pathname from the path variable. You may assume that only one pathname is removed at a time. Also, you need to restore your PATH environment variable to its original state when the user exits your shell.
  4. Add a new built-in history command that lists your shell history of previous commands. It is up to you to select what number of prior commands to keep in history. history –c command should clear your history list. history N, where N is number, displays your prior N-th command starting with the last one. history N -e executes your prior N-th command.

OPTIONAL assignments for extra credits:

  1. Extend your shell with I/O redirection: <, >, >> (+20%).
  2. Extend your shell with pipelining | (+20%).

DEFENSIVE PROGRAMMING (GROUP COLLABORATIVE EFFORT): Check the return values of all system calls utilizing system resources. Do not blindly assume all requests for memory will succeed and that all writes to a file will occur correctly. Your code should handle errors properly. In general, there should be no circumstances in which your C program will core dump, hang indefinitely, or prematurely terminate. Therefore, your program must respond to all input by printing a meaningful error message and either continue processing or exit, depending upon the situation. Many questions about functions and system behavior can be found in the manual pages. You should handle the following situations:

  • An incorrect number of command line arguments to your shell program;
  • The batch file does not exist or cannot be opened.
  • A command does not exist or cannot be executed.
  • A very long command line (over 512 characters including the ‘n’).

REQUIREMENTS: Your code must be written in C.

GRADING: Your C program file(s), README, and makefile shall be committed to our GitLab environment as follows:

  • Your C program file(s). Your code should be well documented in terms of comments. For example, good comments in general consist of a header (with your name, course section, date, and brief description), comments for each variable, and commented blocks of code.
  • A README file with some basic documentation about your code. This file should contain the following four components:

Your name(s);

Organization of the Project. Since there are multiple components in this project, you will describe how the work was organized and managed, including which team members were responsible for what components – there are lots of ways to do this, so your team needs to come up with the best way that works based on your team’s strengths. Note that this may be used in assessment of grades for this project.

Design Overview: A few paragraphs describing the overall structure of your code and any important structures.

Known Bugs or Problems: A list of any features that you did not implement or that you know are not working correctly.

  • A Makefile for compiling your source code, including a clean directive.
  • Your program will be graded based largely on whether it works correctly on the CSE machines.

EXECUTIVE SUMMARY

/in /by

  

In this assignment, you will propose a quality improvement initiative from your place of employment that could easily be implemented if approved. Assume you are presenting this program to the board for approval of funding. Write an executive summary (750-1,000 words) to present to the board, from which the board will make its decision to fund your program or project. Include the following:

1. The purpose of the quality improvement initiative.

2. The target population or audience.

3. The benefits of the quality improvement initiative.

4. The interprofessional collaboration that would be required to implement the quality improvement initiative.

5. The cost or budget justification.

6. The basis upon which the quality improvement initiative will be evaluated. Prepare this assignment according to the guidelines found in the APA Style Guide, located in the Student Success Center. An abstract is not required.

This assignment uses a rubric. Please review the rubric prior to beginning the assignment to become familiar with the expectations for successful completion. 

Make sure to use headers to separate the Rubric topics and make sure you provide enough depth for each required rubric section. The Thesis and the Purpose of the Executive Summary are two different things for this paper. Write the Thesis first and then create a header for the Purpose and enter the purpose of your proposal as if you are now delivering this presentation to your upper management. Please follow the rubric as this is how I must grade your paper.

Your paper will consist of the title page, thesis, 6 headers for the 6 topics and a reference page.

Aerodynamic Unaccelerated Performance

/in /by

 In this module week, you will apply your gained knowledge about unaccelerated aircraft performance. Since you will build on your previously derived drag data for your example aircraft.

 

For your independent project, create an instructional presentation. Using/building on your previous drag (i.e., thrust-required) table and graph created in Module 3, generate additional power-required values in the table and depict the power-required curve for your aircraft.  

Then, working with your derived thrust-required and/or power-required curves and table data, explain how to find various performance aspects for your aircraft, and provide the specific data for your example. At a minimum cover the following:

  • Maximum range airspeed
  • Maximum endurance airspeed
  • Best climb conditions
    • Best rate of climb (ROC) & associated airspeed
    • Best angle of climb (AOC) & associated airspeed
  • Maximum forward airspeed
  • Best glide airspeed

Additionally, discuss and highlight numerically on a specific example of how weight change influences performance events such as the best range or endurance.

As in previous assignments, you will need to research additional information such as required formulas and pertinent aircraft data. Again, the emphasis in this project task is on explaining your methodology as if you are attempting to instruct someone unfamiliar with the aerodynamic details and relationships. Therefore, make sure to detail all assumptions, all formulas used, and all steps that were taken. The following will give you some starting points for your search and consideration. 

  1. Required formula:
    • Thrust to power relationship
    • Weight change influence on performance airspeeds
    • ROC & AOC relationships
  2. Necessary aircraft information:
    • Powerplant output (for simplification, you can assume constant power output at the rated value across the entire speed range); whatever powerplant data you utilize, please make sure to include a short discussion detailing your assumptions.
  3. Previous information:
    • Make sure to detail again all assumed information used/transferred from last week (e.g., aircraft weight, atmospheric conditions, etc.) since performance data are, obviously, only valid for specific cases and conditions.

As previously stated, you are encouraged to utilize appropriate computational software such as Excel® or MatLab®. 

  • Your presentation is due by the last day of the module and should be created using Powerpoint or the presentation platform of your choice.

Guidelines for Focused SOAP Notes

· Label each section of the SOAP note (each body part and system).

· Do not use unnecessary words or complete sentences.

· Use Standard Abbreviations 

S: SUBJECTIVE DATA (information the patient/caregiver tells you).

Chief Complaint (CC): a statement describing the patient’s symptoms, problems, condition, diagnosis, physician-recommended return(s) for this patient visit. The patient’s own words should be in quotes. 

History of present illness (HPI): a chronological description of the development of the patient’s chief complaint from the first symptom or from the previous encounter to the present. Include the eight variables (Onset, Location, Duration, Characteristics, Aggravating Factors, Relieving Factors, Treatment, Severity-OLDCARTS), or an update on health status since the last patient encounter. 

Past Medical History (PMH): Update current medications, allergies, prior illnesses and injuries, operations and hospitalizations allergies, age-appropriate immunization status. 

Family History (FH): Update significant medical information about the patient’s family (parents, siblings, and children). Include specific diseases related to problems identified in CC, HPI or ROS. 

Social History(SH): An age-appropriate review of significant activities that may include information such as marital status, living arrangements, occupation, history of use of drugs, alcohol or tobacco, extent of education and sexual history. 

Review of Systems (ROS). There are 14 systems for review. List positive findings and pertinent negatives in systems directly related to the systems identified in the CC and symptoms which have occurred since last visit; (1) constitutional symptoms (e.g., fever, weight loss), (2) eyes, (3) ears, nose, mouth and throat, (4) cardiovascular, (5) respiratory, (6) gastrointestinal, (7) genitourinary, (8) musculoskeletal, (9-}.integument (skin and/or breast), (10) neurological, (11) psychiatric, (12) endocrine, (13) hematological/lymphatic, {14) allergic/immunologic. The ROS should mirror the PE findings section.

0: OBJECTIVE DATA (information you observe, assessment findings, lab results). 

Sufficient physical exam should be performed to evaluate areas suggested by the history and patient’s progress since last visit. Document specific abnormal and relevant negative findings. Abnormal or unexpected findings should be described. You should include only the information which was provided in the case study, do not include additional data. 

Record observations for the following systems if applicable to this patient encounter (there are 12 possible systems for examination): Constitutional (e.g. vita! signs, general appearance), Eyes, ENT/mouth, Cardiovascular, Respiratory, GI, GU, Musculoskeletal, Skin, Neurological, Psychiatric, Hematological/lymphatic/immunologic/lab testing. The focused PE should only include systems for which you have been given data. 

NOTE: Cardiovascular and Respiratory systems should be assessed on every patient regardless of the chief complaint.

Testing Results: Results of any diagnostic or lab testing ordered during that patient visit. 

A: ASSESSMENT: (this is your diagnosis (es) with the appropriate ICD 10 code)

 

List and number the possible diagnoses (problems) you have identified. These diagnoses are the conclusions you have drawn from the subjective and objective data. 

Remember: Your subjective and objective data should support your diagnoses and your therapeutic plan.

Do not write that a diagnosis is to be “ruled out” rather state the working definitions of each differential or primary diagnosis (es).

For each diagnoses provide a cited rationale for choosing this diagnosis. This rationale includes a one sentence cited definition of the diagnosis (es) the pathophysiology, the common signs and symptoms, the patients presenting signs and symptoms and the focused PE findings and tests results that support the dx. Include the interpretation of all lab data given in the case study and explain how those results support your chosen diagnosis. 

P: PLAN (this is your treatment plan specific to this patient). Each step of your plan must include an EBP citation. 

1. Medications write out the prescription including dispensing information and provide EBP to support ordering each medication. Be sure to include both prescription and OTC medications. 

2. Additional diagnostic tests include EBP citations to support ordering additional tests

3. Education this is part of the chart and should be brief, this is not a patient education sheet and needs to have a reference. 

4. Referrals include citations to support a referral 

5. Follow up. Patient follow-up should be specified with time or circumstances of return. You must provide a reference for your decision on when to follow up.

QUESTION 2

Human blood is classified by the presence or absence of three main antigens (A, B, and Rh). When a blood specimen is typed, the presence of the A and/or B antigen is indicated by listing the letter A and/or the letter B. If neither the A nor B antigen is present, the letter O is used. The presence or absence of the Rh antigen is indicated by the symbols + or -, respectively. Thus, if a blood specimen is classified as AB +, it contains the A and the B antigens as well as the Rh antigen. Similarly, O- blood contains none of the three antigens.

Using this information, determine the sample space corresponding to the different blood groups.
