Write a Python program

The Hay System is a job performance evaluation method that is widely used by organizations around the world. Corporations use the system to map out their job roles in the context of the organizational structure. One of the key benefits of the method is that it allows for setting competitive, value-based pay policies. The main idea is that for each job evaluation, a number of factors (such as Skill, Effort, Responsibility and Working Conditions) are evaluated and scored by using a point system. Then, the cumulative total of points obtained will be correlated with the salary associated with the job position. As an engineering student, you have been commissioned to implement a simplified version of the Hay method. Particularly, the hiring company (which is called David and Joseph Ltd) is interested in getting the salary (or hay system score) for several job descriptions currently performed in the company. Data Representation Unfortunately, the company David and Joseph Ltd. has very strict security policies. Then, you will not be granted access to the main data base ). Instead, all the information needed has been compiled in files with the following characteristics. File 1 The first line of the file contains 1 positive integer: num words≤ 10000, the number of words in the Hay Point dictionary. num words lines follow; each contains a word (a string of up to 16 lower-case letters) and a dollar value (an integer between 0 and 1000000).

You can safely assume that the num words words in the dictionary are distinct. Each description word-value is terminated by a line containing a period. You can take a look about how File 1 looks below.

7
administer 100000
.
spending 200000
.
manage 50000
.
responsibility 25000
.
expertise 100
.
skill 50
.
money 75000
.

Please note that for this file, num words is equal to 7. File 2 The first lines of the file contains a varyingly number of comments that must be ignored. You can recognize a comment line because it always start with the # character. Following the comments there is one job description. A job description consists of between 1 and 200 lines of text; for your convenience the text has been converted to lower case and has no characters other than letters, numbers, and spaces. Each line is at most 200 characters long. You can take a look about how File 2.1 looks below.

#Hello how are you

# This comment does not make sense

# It is just to make it harder

# The job description starts after this comment, notice that it has 4 lines.

# This job description has 700150 hay system points \\

the incumbent will administer the spending of kindergarden milk money and exercise responsibility for making change he or she will share responsibility for the task of managing the money with the assistant whose skill and expertise shall ensure the successful spending exercise

Below, you can find a second example of how File 2.2 could look like.

#This example has only one comment

this individual must have the skill to perform a heart transplant

and expertise in rocket science

The Hay System When applying the Hay System to the latest File 2 example (i.e., this individual must have the skill to perform a heart transplant and expertise in rocket science ) on the Hay Point dictionary coded in File 1, the job description gets a total of 150 points (or salary in dollars). This score is obtained because exactly two words (i.e., expertise and skill) of the job description are found in the dictionary. Particularly, expertise and skill have a score of 100 and 50 dollars, respectivelly.

Question 1: create dictionary

Complete the create dictionary function, which reads the information coded in the File 1 and returns a hay points dictionary. See below for an explanation of exactly what is expected. from typing import Dict, TextIO def create_dictionary(file1: TextIO) -> Dict[str, int]: ’’’Return a dictionary populated with the information coded in file1. >>> File_1 = open(’File1.txt’) >>> hay_dict = create_dictionary(File_1) >>> hay_dict {’administer’: 100000, ’spending’: 200000, ’manage’: 50000, ’responsibility’: 25000, ’expertise’: 100, ’skill’: 50, ’money’: 75000} """ Please note that the variable file1 is of type TextIO, then you can assume that file was already open and it is ready to be read.

Question 2: job description (24 points) Complete the job description function, which reads the information coded in the File 2 to return a list of strings with the job description. See below for an explanation of exactly what is expected. def job_description(file2: TextIO) -> List[str]: ’’’Return a string with the job description information coded in file2. >>> File_2 = open(’File2_1.txt’) >>> job_desc = job_description(File_2) >>> job_desc [’the’, ’incumbent’, ’will’, ’administer’, ’the’, ’spending’, ’of’, ’kindergarden’, ’milk’, ’money’, ’and’, ’exercise’, ’responsibility’, ’for’, ’making’, ’change’, ’he’, ’or’, ’she’, ’will’, ’share’, ’responsibility’, ’for’, ’the’, ’task’, ’of’, ’managing’, ’the’, ’money’, ’with’, ’the’, ’assistant’, ’whose’, ’skill’, ’and’, ’expertise’, ’shall’, ’ensure’, ’the’, ’successful’, ’spending’, ’exercise’] ’’’ Please note that the variable file2 is of type TextIO, then you can assume that file was already open and it is ready to be read.

Question 3: hay points (24 points) Complete the hay points function, which for a job description, output the corresponding salary computed as the sum of the Hay Point values for all words that appear in the description. Words that do not appear in the dictionary have a value of 0. See below for an explanation of exactly what is expected. def hay_points(hay_dictionary: Dict[str, int], job_description: List[str]) -> int: ’’’Returns the salary computed as the sum of the Hay Point values for all words that appear in job_description based on the points coded in hay_dictionary >>> File_1 = open(’File1.txt’) >>> File_2 = open(’File2_1.txt’) >>> hay_dict = create_dictionary(File_1) >>> job_desc = job_description(File_2) >>> points = hay_points(hay_dict, job_desc) >>> print(points) >>> 700150 ’’’

Question 4: my test (0 points) The function my test is there to give you a starting point to test your functions. Please note that this function will not be graded, and it is there only to make sure that you understand what every function is expected to do and to test your own code. Note: In order for you to test your functions one at a time, comment out the portions of the my test() function that call functions you have not yet written. The expected output for the function calls is as follows:

The dictionary read from File1.txt is: {’administer’: 100000, ’spending’: 200000, ’manage’: 50000, ’responsibility’: 25000, ’expertise’: 100, ’skill’: 50, ’money’: 75000}

The string read from File2_1.txt is: [’the’, ’incumbent’, ’will’, ’administer’, ’the’, ’spending’, ’of’, ’kindergarden’, ’milk’, ’money’, ’and’, ’exercise’, ’responsibility’, ’for’, ’making’, ’change’, ’he’, ’or’, ’she’, ’will’, ’share’, ’responsibility’, ’for’, ’the’, ’task’, ’of’, ’managing’, ’the’, ’money’, ’with’, ’the’, ’assistant’, ’whose’, ’skill’, ’and’, ’expertise’, ’shall’, ’ensure’, ’the’, ’successful’, ’spending’, ’exercise’]

The salary computed is 700150

How COVID-19 is driving a long-overdue revolution in education

• The pandemic has forced universities to bring their courses online.
• This is just one step along the road to a new educational paradigm, however.
• We can expect a new model to emerge once COVID-19 has passed.

The pandemic that has shuttered economies around the world has also battered education systems in developing and developed countries. Some 1.5 billion students — close to 90% of all primary, secondary and tertiary learners in the world — are no longer able to physically go to school. The impact has been dramatic and transformative as educators scramble to put in place workable short-term solutions for remote teaching and learning, particularly in emerging markets, where students and schools face additional challenges related to financing and available infrastructure.

While each level of education faces its unique challenges, it is the higher education segment that may end up, by necessity, triggering a learning revolution. Universities are distinctive in that their students are both old enough to handle the rigours of online work and technologically savvy enough to navigate new platforms. The real challenge lies for the institutions in which they have enrolled. Can traditional, campus-based universities adapt by choosing the right technologies and approaches for educating and engaging their students? The successes and failures that unfold should give us all a better grasp of what is possible.

Right now, video-conferencing apps like Zoom and WebEx are throwing universities a lifeline. However, lecturers are still struggling to maintain the same depth of engagement with students they could have in a classroom setting. They need to find solutions — and fast — to avoid a dip in the quality of education they are providing. Online education platforms such as Coursera, an IFC client with a global presence, can play a useful role by tapping their expertise in online programme design, choice of tech platform, and digital marketing to develop the best content either with or for the traditional players.

With the online segment still comprising a small fraction of the $2.2 trillion global higher education market — less than 2%, according to market intelligence firm HolonIQ — the market is ripe for disruption. The appetite from students for online offerings will likely grow because of COVID-19. Even before the pandemic, many universities were seeing declines in enrolment for campus-based programmes and parallel increases in uptake of their online courses. With COVID-19, we are seeing how yesterday’s disruptors can become today’s lifeguards. While traditional institutions once viewed online education as a threat, it has come to their rescue.

The adoption of online solutions in recent months has been unprecedented. In the short term, educators are applying a ‘first aid’ solution by switching entirely from in-person to remote instruction, a move that has been forced upon them by sudden mandatory campus closures. But they are quickly realizing that remote learning is just a baby step experiment in the long journey to offering online education that has been conceived as such, which includes effective student engagement tools and teacher training. Some of the partnerships sparked between universities, online education companies and tech providers may continue beyond the pandemic.

As painful and stressful a time as this is, it may fashion a long overdue and welcome rebirth of our education systems. The pandemic has been a great leveller in a way, giving all stakeholders (educators, learners, policy-makers and society at large) in developed and developing countries a better understanding of our current education systems’ vulnerabilities and shortcomings. It has underscored how indispensable it is for our populations to be digitally literate to function and progress in a world in which social distancing, greater digitalization of services and more digitally-centered communications may increasingly become the norm. More fundamentally, COVID-19 is causing us to challenge deep-rooted notions of when, where, and how we deliver education, of the role of colleges and universities, the importance of lifelong learning, and the distinction we draw between traditional and non-traditional learners.

This pandemic has also made people realize how dependent we are on so-called low-skilled workers to keep our lives going. During shutdowns, lockdowns, curfews, it’s these workers who are on the front lines, working multiple shifts to maintain delivery and take care of our basic needs. Over time, automation will continue to eat into these jobs. While there will always be services provided by low-skilled workers, most new jobs will require higher skills levels. Being able to reskill and upskill in this rapidly changing world is not only a necessity but an economic imperative.

COVID-19 has struck our education system like a lightning bolt and shaken it to its core. Just as the First Industrial Revolution forged today’s system of education, we can expect a different kind of educational model to emerge from COVID-19.

Case: Investment Proposals for Ontario Coffee Home

It is January 1, 2019. You are a Senior Analyst at Ontario Coffee Home (OCH), one of the leading coffee chains and wholesaler of coffee/bakery products in Ontario. The CEO of Ontario Coffee Home, Jerry Donovan, has reached out to you to draft a report to evaluate two investment proposals.

Requirements

1.      Identify which revenues and costs are relevant to your analysis, and which costs are irrelevant. Summarize all the information that will be required for each investment proposal, including describing the proposal and identifying the time horizon for each proposal evaluation.

2.      Calculate the after-tax cash flows during the life of each of the projects.

3.      Utilizing the after-tax cash flows from question 2, evaluate each investment proposal utilizing the following criteria (unless directed otherwise):

a.      Payback

b.      NPV

4.      Clearly indicate whether any of the above criteria support each of the project proposals, and what the company should ultimately decide to do.

Investment Proposals

Jerry Donovan, CEO of OCH, wants you to evaluate two investment proposals that the company is considering:

1.      The purchase of a coffee roaster plant in Cuba.

2.      The re-development of coffee shops to accommodate the selling of frozen yogurt.

Mr. Donovan reminds you that only relevant costs and revenues should be considered. “Relevant costs have to be occurring in the future,” explained Mr. Donovan. “And have to differ from the status quo. For example, if we choose to buy the roaster plant, it is only the incremental revenue and costs related to the purchase that should be considered. We also need to take into account the opportunity cost associated with the alternatives.”

More details on each investment proposal are included below. Mr. Donovan wants you to recommend if OCH should invest in one, both, or none of the investment proposals.

Required Return

Mr. Donovan wants you to use 7% as the discount rate (i.e., the required return).

Investment in Roasted Coffee Plant

Mr. Donovan is considering purchasing a coffee plant in Cuba where labour is cheap and there are proximal coffee farms to help lower transportation costs.

The acquisition price of the plant is $6M, which includes roasting equipment that originally cost $14M when it was purchased 8 years ago. Some of the equipment is on its last legs, so an additional $2M of equipment has to be purchased. The roaster plant currently has $2M of available tax shield left, excluding any tax shield related to the equipment to be purchased.

The direct materials and direct labour used to manufacture these products are 8% and 7% of sales, respectively. The actual roasting processing costs are approximately 17% of sales. These costs as a percentage of sales are expected to remain consistent over the time horizon. The plant also requires two managers with fixed salaries of $50,000 each per year. Insurance for the plant and equipment is $40,000 per year.

Other incremental manufacturing overhead costs (property taxes, maintenance, security, etc.) excluding depreciation are estimated to be $75,000 annually. Wages are expected to increase with inflation (estimated to be 2%) over the time period, while other fixed costs are expected to remain steady.

Transportation variable costs (gas, variable overhead, etc.) are estimated to be 12% of revenue, and include transportation of raw materials to the roaster and finished products to the port for delivery to OCH coffeehouses.

The roasted coffee plant is expected to produce 1.1M pounds of coffee for the first two years, with production dipping by 100,000 pounds per year after this due to lower productivity from the deteriorating equipment. Each pound of roasted coffee can be sold at $3.25 per pound (either to retail cafes, franchise cafes, or to wholesale partners), with the price expected to rise with inflation over time. Each pound of coffee can make 30 cups of coffee that can sell at an average retail price of $4.00 per cup. Mr. Donovan has stressed that the profitability of the plant base has to be looked at on a stand-alone basis, i.e., from the sales from the plant to buyers, not from retail cafés to customers.

Mr. Donovan wants to see if the project will reach profitability after 5 years, as significant reinvestment will be needed after five years to keep the plant operational, so he wants you to evaluate the return on investment in that period using the investment criteria of payback period, NPV, and IRR. The following table will help in the calculations of the tax shield for the new equipment:

Assume no salvage value when calculating the tax shield, and that the half-year rule applies for Class 43. The tax rate Mr. Donovan wants you to utilize is 25%. When calculating the tax shield, the present value should be in the same period as the initial investment (Year 0), which also means that deprecation (i.e., CCA) should not be taken from the cash flows in subsequent years since their tax shelter effects are already accounted for in the tax shield.

Redevelopment of Coffee Shops

Mr. Donovan also wants you to evaluate the potential of developing several hundred stores into new store models with frozen yogurt services. Five hundred stores have been selected as candidates for development. It will cost $80,000 to convert each store, including modifications to refrigeration equipment, with these costs being capitalized with a 6% applicable CCA rate. The average modified coffee shop is expected to generate an additional $30,000 in after-tax cash flow every year. However, OCH is also estimated to lose about $15,000 in annual after-tax cash flow from these cafés due to yogurt sales cannibalizing existing coffee shops. In other words, some customers who normally would have purchased coffee would instead purchase yogurt.

The five hundred stores have average annual rent of $36,000 each. Mr. Donovan wants you to evaluate the profitability of this investment after a seven-year period using the investment criteria of NPV.

Overview

Your assignment is to complete a wireless network design for a small company. You will place a number of network elements on the diagram and label them appropriately. A network diagram is important to communicate the design features of a network between network administrators, system administrators and cyber-security analysts. It helps to create a shared mental model between these different technologists, yet each will have their own perspective on what is important to have documented on the diagram. Please review a description of ABC Corporation’s network resources and how they are allocated.

You may find the following Floor Plan helpful in completing this lab.

ABC Corporation’s Network Description

ABC Corporation is a small business in the heart of Central Pennsylvania. They provide services to their clients all over the region. The three-story main office building is where all of the employees report to work each day. There are no remote users. ABC Corporation is a very traditional business. While they have a computer network and are connected to the Internet, they aren’t very fancy and don’t yet have a need for telecommuting, wireless networks, or smart phones. All of their computers are desktop machines and are connected with wired Ethernet connections. All of the network wiring is CAT-6 twisted pair wiring that goes from the office location to a wiring closet. There is one wiring closet on each floor. Each closet is connected to the basement wiring closet via fiber.

There are several departments of the company. The administrative office has ten employees including the CEO, executive Vice-President, a human resources manager, and several assistants and secretaries. The finance office has fifteen employees. Both of these divisions are on the third floor.

The second floor has the Sales and R&D departments. There are a total of twenty employees in the Sales Department and includes sales executives and assistants. All of the sales department personnel have laptop computers, but they are still connected via the wired network. The R&D department has ten engineers who have two computers each – one in their office and one in their lab spaces.

The first floor has the shipping/receiving department, manufacturing department and the receptionist. The receptionist shares a computer with the night watchman, since they work opposite shifts. There are 20 people in manufacturing, but they only use three computers to enter their production details into the company’s ERP system. The shipping/receiving department has six people, each with a computer that connects to UPS, Fedex and USPS systems, prints packaging labels and shipping documents. There is also a conference room/training room on the first floor with a multimedia system that includes a podium computer, projector, and all of the bells and whistles.

The basement houses the maintenance department, information technology, and the mail room. The mail room clerk doesn’t use the computers at all. The two maintenance workers have computers at their desks that they use to enter reports of work performed. The IT Department has seven employees, each with a desktop computer. They also manage the server farm, which includes two domain controllers, one print server, one mail server, one database server, one internal web server, one external web server (on the DMZ interface of the firewall), a file server, a special server for the ERP system, and a backup server.

Add Wireless Network Access Points

Each floor, with the exception of the basement (the basement does not need wireless), needs to have two wireless access points, one for the north end of the building, and the other for the south. However, the wireless access points will overlap in the middle of the building, so you need to pick different wireless network channels for each end. On the first floor, there should be an additional wireless access point in the conference room for guests.

The “guest” network should have a different SSID than the company’s wireless network. It should be configured to allow anyone to connect with a password. The password will be provided by the receptionist to any visitors and will be changed each week. The company wireless network should be configured to have the same SSID on all of the wireless network access points (but different from the “guest” network). It should be configured with WPA-2 Enterprise with AES and should be connected to the company’s servers for authentication (Windows Server with RADIUS server enabled for the Active Directory).

Note: You might want to review this informative webpage to see how to configure Windows Server to handle the authentication for the access points.

Place your network access points on your network diagram you did for Homework #2. Segment the wireless network separately from the wired network so that it is on its own subnet. Segment the visitor wireless network so it’s on its own subnet, separate from both the wired network and the company wireless network.

Label each access point with its own IP address and basic configuration. Each device should have its own name, IP address and should list its configuration in terms of encryption protocol (TKIP, AES, 3-DES or None) and authentication protocol (WPA, WPA-Enterprise, WPA2-Enterprise, WPA-2, WEP, etc, none, etc). Identify the SSIDs that are used for each device.

Place the wireless access points in the building. You may use the floor plan provided in the attached PDF.  

Create a Network Diagram

Your network diagram needs to include the following elements:

• Each Wireless Access Point (WAP)
• Each WAP’s critical configuration details – name, IP address, SSID, connection protocols, encryption protocols and wireless channel
• The Windows authentication server – including name, IP address, and important configuration details
• Additional switches and connections between the building’s floors to establish the network(s)
• IP Address ranges that will be assigned to network devices when they join the wireless networks

Network Documentation

Your network design document needs to explain each of the elements in your wireless network design. Explain how you segmented your wireless network from other parts of the network. Describe what security settings you might want to implement in your router. Describe the reason for the number of access points that you need on each floor.

What to Turn In

For assignments that require you to submit Visio work, please export your file and submit as a PDF. Also, please submit your original Visio file.
You also need to turn in a Word document (.doc or .docx) file that explains your network diagram elements. Include snapshots from your network diagram in your Word doc file – and annotate your diagram snapshots to better help your explanation of your network.

In this lab, you will be completing a programming exercise through the point of view of both a

contracted library developer and the client that will use the developed code.

In the first part, you will be required to write a class in C++ that will be included in the client’s code.

Your class must be written with defensive programming in mind. It should allow the client to include or

leave out your defensive checks at compile-time.In the second part, you will use your defensively

programmed class methods to guide the revision of the provided user driver program. After

encountering failures from misuse of the library class methods, you will update the driver program,

according to the implementation guidelines in the CWE documentation for the appropriate error.

Note that the code you write does not have to be completely optimized and you will likely see better

ways to write the class and the driver to avoid the problems inherit in the client descriptions.

In Part 1 of the lab you will complete the following:

 Write a class called myArray in a file named “yourlastname_lab2.cpp” where you substitute your

own name

            o Constructor

                       two inputs: int size and string input

                       dynamically create a char* array of int size

                       parse string input (which should be a string of comma-separated characters)

                              and enter the characters in the array in order

           o Destructor should free the memory assigned to your char* array

          o ReadFromArray

                 one input: int index

                 return char at the given index for the array

       o WriteToArray

               two inputs: int index, char replace

               overwrite char at given index with new char replace

    o DeleteArray

                 free the memory for your char*

             set char* to NULL

o PrintArray

                output the contents of the char* array to stdout

o NewArray

               two inputs: int size and string input

              dynamically create a char* array of int size

              parse string input (which should be a string of comma-separated characters)

             and enter the characters in the array in order

               For each class method, provide the contract for proper usage of the method

o enter as comment lines directly after the definition

o List any preconditions (what has to be true immediately before executing the method)o List any postconditions (what has to be true immediately after executing the method)

               Utilize C standard assert() library calls from assert.h to test your preconditions

               Use macros to give the client the option on whether to include the asserts at compile-time

               Use the provided sample client driver program to test your class code

                Take screenshots of your assertions being invoked for each function

In Part 2 of the lab you will complete the following:

• Using the assertions you have placed into your class methods, update the driver code to ensure

calls made to the class methods are in-contract

• Identify what CWE errors, if applicable, are occurring with out-of-contract use of your class

methods

• Review the ‘Potential Mitigation” section for those CWE errors and use the “Phase:

Implementation” entries to guide your revision of the provided program driver.

• Take screenshots of the driver code working without hitting the assertions – be sure to explain

in your word document how you tested the preconditions of each method and what changes

you made to the driver to ensure in-contract calls were made to the methods.

Graduate students should also answer the following:

• Is there a Python equivalent to the C-standard assert() calls used in class with C++?

• How would you approach defensive programming from the point-of-view of python methods?

Submit a zip file to Blackboard which contains your class file and a word document which includes the

screenshots and other information described above.

For full credit your code should compile, run as described, and be appropriately commented. If I need to

know anything in particular about how I should compile your code, include that in your document.

Problem:      Construct and interpret a 90%, 95%, and 99% confidence interval for the mean heights of either adult females or the average height of adult males living in America. Do not mix genders in your sample as this will skew your results. Gather a random sample of size 30 of heights from your friends, family, church members, strangers, etc. by asking each individual in your sample his or her height. From your raw data convert individual heights to inches. Record your raw data and your conversions in the table on page 2 of this document. Construct and interpret the confidence interval based on the raw data from your random sample. In a word processed document, answer the reflections questions below. Use the equation editor to show your calculations for the percent difference indicated in 6) below.

Reflections: 1)            Summarize the characteristics of your sample – how many was in it, who was in it, from where did you get your sample, what would you estimate to be the average age of your sample, etc.?

2) What is x for your sample?

3) What is s for your sample?

3) State and interpret the 90% confidence interval for your sample.

4) State and interpret the 95% confidence interval for your sample.

5) State and interpret the 99% confidence interval for your sample.

6) Research from a credible source the average height in the population as a whole for the group you sampled. Make sure to credit your source. Calculate a percent difference between the average of your sample and the average in the population as a whole.   What was the percent difference of the average height in your sample and the population as a whole? Comment on your percent difference.

Preparation of Individual Budgets

During the first calendar quarter of 2019, Clinton Corporation is planning to manufacture a new product and introduce it in two regions. Market research indicates that sales will be 6,000 units in the urban region at a unit price of $53 and 5,000 units in the rural region at $48 each. Because the sales manager expects the product to catch on, he has asked for production sufficient to generate a 4,000-unit ending inventory. The production manager has furnished the following estimates related to manufacturing costs and operating expenses:

*Varies per unit sold, not per unit produced.

a. Assuming that the desired ending inventories of materials A and B are 4,000 and 6,000 pounds, respectively, and that work-in-process inventories are immaterial, prepare budgets for the calendar quarter in which the new product will be introduced for each of the following operating factors:
