Henry Ford- majority shareholder of the Ford Motor Company- announced.pdf
Henry Ford, majority shareholder of the Ford Motor Company, announced that rather than pay a
special dividend to the company's shareholders, he was going to reinvest the accumulated
earnings in order to expand the company and hire more workers. He further indicated that he
wished to lower the price of the Model T car to make it more accessible to the general public.
Two minority shareholders, John and Horace Dodge, sued to require payment of the dividend.
The court upheld management's right to make decisions for the benefit of the company; however,
the court said that "the corporation is a business, not a charity," and found for the Dodges
because Henry Ford's decision was to benefit the public instead of shareholders.

case?

Help create the vcipher-h and vcipher-cc files for the vigenere cipher.pdf
Help create the vcipher.h and vcipher.cc files for the vigenere cipher which MUST inherit
from substitution and running key cipher(kcipher.h and kcipher.cc). Please follow the
instructions and complete the provided code:
Substitution cipher (implemented in cipher.h and cipher.cc) class has already been defined (but
not implemented) for you. The other cipher classes MUST
a) inherit from the substitution cipher, or
b) inherit from one of the four other cipher classes (e.g., Caesar inherits from Substitution,
ROT13 inherits from Caesar).
4. Each new cipher class MUST have a constructor, a default constructor (except the ROT13
cipher, as described below), and a destructor .
a) Each constructor should accept the input appropriate for the cipher:
i) substitution - cipher alphabet - must contain every letter in the alphabet, and only once, and
they must all be lower case. It should contain no other characters (e.g., no space, punctuation,
etc.). Cipher alphabet length should always be 26.
iv) Running Key - a vector of strings. The vector represents the cipher "book," and each element
in the vector is a "page" from the book. Each page should be a non-empty string. This string
should consist of only lower case letter or spaces.
v) Vigenere - a string representing the key word. The key word should consist of only lower case
letters.
b) Each default constructor should not accept any inputs.
ii) Other ciphers: default constructor should initialize the object so that encrypting any plain text
should return a cipher text that is identical to the plain text. For example, for Caesar, setting the
shift to 0 will achieve this. YOU CANNOT SIMPLY RETURN THE PLAIN TEXT - IT MUST
STILL ENCRYPT THE TEXT using the proper method.
b) the destructor should free all memory. Valgrind will be used to make sure there are no
memory leaks.
5. Each cipher must also provide encrypt and decrypt functions. They can either be implemented
explicitly, or implicitly using inheritance. This is a design decision, but the decision should be
made to minimize/modularize your code.
i) Encrypt: Assume that the input plain text will always be a) lower case letter, b) upper case
letter, or c) a space. Space should not be encrypted (i.e., if the plain text is "hello world", the
encrypted text should look something like "abcde fghij". Upper case letter should be encrypted to
an upper case letter (you don't have to, but you will find that meeting the decrypt requirement
below will be difficult otherwise).
ii) Decrypt: This should take in the encrypted text and return the origin plain text. It should
a) retain the case (i.e., if the input plain text has an upper case letter, the decrypted plain text
should have that letter as upper case.
b) retain the space - If the plain text had spaces, the decrypted text should still have those spaces
in the correct place.
6. Data members in all cipher classes should be hidden using the Cheshire smile.
7. Each cipher should also check to make sure that the pr.
Help implement BST- The code must follow the instruction below as well.pdf
Help implement BST. The code must follow the instruction below as well as produce the
correct output when testing with the input file I'll provide at the end. Please fill-in the
TODO parts in the bst.cc code:
INSTRUCTIONS:
3. First, implement the BST (declared in bst.h) and use the unittest_bst() function to test it. DO
NOT CHANGE THIS CODE FOR YOUR SUBMISSION, as it will be used to test your code
against the answers (with different seed values).
4. Implement the DB and use the unittest_db() function to test it. DO NOT CHANGE THIS
CODE FOR YOUR SUBMISSION, as it will be used to test your code against the answers (with
different input files).
a) The student ID should be the base class's key member.
b) The student ID should be automatically assigned such that the ID/key should be n if the
student is the nth student to join the school. If the student later leaves (i.e., deleted from the
BST), the ID does NOT get reassigned to another student. Thus, the student ID of the last student
to join the school should reflect the TOTAL number of students that have joined this school
since its reception (regardless of whether some have left).
5. Test your code against the provided input and output files.
a) The provided answer for the BST unit test is in "unittest_ans_t100_s100.txt". The s100 refers
to the seed of 100 (-s 100), and t100 refers to the number of elements to add to the BST (-t 100).
b) The provided answer for the DB is in "students_1_ans.txt" for the "students_1.txt" input file.
6. Make sure your code has no memory leaks (using valgrind).
7. Your code should work beyond the provided unit tests. That is, even if it does work for all the
given tests, if the code has an identifiable bug (i.e., by reading the source code), points WILL be
deducted.
For example, if I were to change
unittest_bst(num_test, seed, cout, 5); ->
unittest_bst(num_test, seed, cout, 100);
it should still work.

Help me create a use case diagram for this use case- Use case title-.pdf
Help me create a use case diagram for this use case:
Use case title: Monitor response times of ambulance crews and take appropriate action if
response times fall outside established ranges
Primary actor: Dispatcher
Level: Primary task
Stakeholders: Dispatchers, Ambulance crews, Patients, Medical Staff
Precondition: Ambulance Crews are assigned to cases, Dispatchers have access to real-time data
on response times and category of cases
Minimal guarantee: Dispatcher can access data on response times and identify cases with
response times outside of the established range
Success guarantee: Dispatcher takes appropriate action to address the issue and response times
are brought back within established ranges
Trigger: Dispatcher receives data on response times for a case outside of the established range
Main success scenario:
Dispatcher receives data on response times for a case outside of the established range
Dispatcher investigates the cause of the issue, such as traffic or a delay in dispatch
Dispatcher takes appropriate action, such as dispatching another ambulance crew or contacting
the original crew to ensure they are on route
Dispatcher ensures that response times are brought back within established ranges
Dispatcher updates the case record with the actions taken and any changes in status
Extensions:
If the cause of the issue is a delay in dispatch, the Dispatcher contacts the relevant personnel to
investigate and address the issue
If the cause of the issue is an unexpected delay on the part of the Ambulance Crew, the
Dispatcher contacts the crew to ensure that they are on route and taking appropriate action to
reach the patient as quickly as possible
If the cause of the issue is due to external factors, such as a road closure or severe weather, the
Dispatcher may need to make alternative arrangements to ensure that the patient receives timely
care.
The French Revolution Class 9 Study Material pdf free download
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

tools to combat economic fiuctuations. The following graph plots hypothetical aggregate demand
(AD), short-run aggregate supply (AS), and long-run aggregate supply (LRAS) curves for the
U.S. economy in January 2026. Suppose the government chooses to intervene in order to return
the economy to the natural level of output by using Depending on which curve is affected by the
government policy, shift either the AS curve or the AD curve to reflect the change that would
successfully restore the natural level of output. Suppose that in January 2026 the government
successfully carries out the type of policy necessary to restore the natural level of output
desoribed in the previous question. In March 2026, U.S. exports increase because india
eliminates all trade restrictions on U.S. goods. Oue to the ascociated with implementing
monetary and fiscal polic, the impact of the govemment's new policy will ikely once the effects
of the poligy are fully realized..

Hemophilia is due to a recessive allele (h) linked to the X chromosome (1).pdf
Hemophilia is due to a recessive allele (h) linked to the X chromosome (XH= normal allele;
Xh=hemophilia allele). David has the condition but his parents do not. David marries Angela,
whose parents do not have the condition. This couple have two children (1 daughter and 1 son).
Their son has hemophilia but their daughter does not.
If the couple had another girl, could this child have the hemophilia condition? If yes, what is the
probability that she has the hemophilia condition? Draw a Punnett square.
If the couple had another boy, would it be possible that he have a normal phenotype (not have
the hemophilia condition)? If yes, what would be the theoretical percentage that does he not have
the condition? Draw a Punnett square..
Henry Ford- majority shareholder of the Ford Motor Company- announced.pdf
Henry Ford, majority shareholder of the Ford Motor Company, announced that rather than pay a
special dividend to the company's shareholders, he was going to reinvest the accumulated
earnings in order to expand the company and hire more workers. He further indicated that he
wished to lower the price of the Model T car to make it more accessible to the general public.
Two minority shareholders, John and Horace Dodge, sued to require payment of the dividend.
The court upheld management's right to make decisions for the benefit of the company; however,
the court said that "the corporation is a business, not a charity," and found for the Dodges
because Henry Ford's decision was to benefit the public instead of shareholders.
1. How do the differing values and business perspectives of Ford and the Dodges influence this
case?
2. Do laws easily allow for both "profits and people" to be maintained?.

Help create the vcipher-h and vcipher-cc files for the vigenere cipher.pdf
Help create the vcipher.h and vcipher.cc files for the vigenere cipher which MUST inherit
from substitution and running key cipher(kcipher.h and kcipher.cc). Please follow the
instructions and complete the provided code:
Substitution cipher (implemented in cipher.h and cipher.cc) class has already been defined (but
not implemented) for you. The other cipher classes MUST
a) inherit from the substitution cipher, or
b) inherit from one of the four other cipher classes (e.g., Caesar inherits from Substitution,
ROT13 inherits from Caesar).
4. Each new cipher class MUST have a constructor, a default constructor (except the ROT13
cipher, as described below), and a destructor .
a) Each constructor should accept the input appropriate for the cipher:
i) substitution - cipher alphabet - must contain every letter in the alphabet, and only once, and
they must all be lower case. It should contain no other characters (e.g., no space, punctuation,
etc.). Cipher alphabet length should always be 26.
iv) Running Key - a vector of strings. The vector represents the cipher "book," and each element
in the vector is a "page" from the book. Each page should be a non-empty string. This string
should consist of only lower case letter or spaces.
v) Vigenere - a string representing the key word. The key word should consist of only lower case
letters.
b) Each default constructor should not accept any inputs.
ii) Other ciphers: default constructor should initialize the object so that encrypting any plain text
should return a cipher text that is identical to the plain text. For example, for Caesar, setting the
shift to 0 will achieve this. YOU CANNOT SIMPLY RETURN THE PLAIN TEXT - IT MUST
STILL ENCRYPT THE TEXT using the proper method.
b) the destructor should free all memory. Valgrind will be used to make sure there are no
memory leaks.
5. Each cipher must also provide encrypt and decrypt functions. They can either be implemented
explicitly, or implicitly using inheritance. This is a design decision, but the decision should be
made to minimize/modularize your code.
i) Encrypt: Assume that the input plain text will always be a) lower case letter, b) upper case
letter, or c) a space. Space should not be encrypted (i.e., if the plain text is "hello world", the
encrypted text should look something like "abcde fghij". Upper case letter should be encrypted to
an upper case letter (you don't have to, but you will find that meeting the decrypt requirement
below will be difficult otherwise).
ii) Decrypt: This should take in the encrypted text and return the origin plain text. It should
a) retain the case (i.e., if the input plain text has an upper case letter, the decrypted plain text
should have that letter as upper case.
b) retain the space - If the plain text had spaces, the decrypted text should still have those spaces
in the correct place.
6. Data members in all cipher classes should be hidden using the Cheshire smile.
7. Each cipher should also check to make sure that the pr.
Help implement BST- The code must follow the instruction below as well.pdf
Help implement BST. The code must follow the instruction below as well as produce the
correct output when testing with the input file I'll provide at the end. Please fill-in the
TODO parts in the bst.cc code:
INSTRUCTIONS:
3. First, implement the BST (declared in bst.h) and use the unittest_bst() function to test it. DO
NOT CHANGE THIS CODE FOR YOUR SUBMISSION, as it will be used to test your code
against the answers (with different seed values).
4. Implement the DB and use the unittest_db() function to test it. DO NOT CHANGE THIS
CODE FOR YOUR SUBMISSION, as it will be used to test your code against the answers (with
different input files).
a) The student ID should be the base class's key member.
b) The student ID should be automatically assigned such that the ID/key should be n if the
student is the nth student to join the school. If the student later leaves (i.e., deleted from the
BST), the ID does NOT get reassigned to another student. Thus, the student ID of the last student
to join the school should reflect the TOTAL number of students that have joined this school
since its reception (regardless of whether some have left).
5. Test your code against the provided input and output files.
a) The provided answer for the BST unit test is in "unittest_ans_t100_s100.txt". The s100 refers
to the seed of 100 (-s 100), and t100 refers to the number of elements to add to the BST (-t 100).
b) The provided answer for the DB is in "students_1_ans.txt" for the "students_1.txt" input file.
6. Make sure your code has no memory leaks (using valgrind).
7. Your code should work beyond the provided unit tests. That is, even if it does work for all the
given tests, if the code has an identifiable bug (i.e., by reading the source code), points WILL be
deducted.
For example, if I were to change
unittest_bst(num_test, seed, cout, 5); ->
unittest_bst(num_test, seed, cout, 100);
it should still work.

Use case title: Monitor response times of ambulance crews and take appropriate action if
response times fall outside established ranges
Primary actor: Dispatcher
Level: Primary task
Stakeholders: Dispatchers, Ambulance crews, Patients, Medical Staff
Precondition: Ambulance Crews are assigned to cases, Dispatchers have access to real-time data
on response times and category of cases
Minimal guarantee: Dispatcher can access data on response times and identify cases with
response times outside of the established range
Success guarantee: Dispatcher takes appropriate action to address the issue and response times
are brought back within established ranges
Trigger: Dispatcher receives data on response times for a case outside of the established range
Main success scenario:
Dispatcher receives data on response times for a case outside of the established range
Dispatcher investigates the cause of the issue, such as traffic or a delay in dispatch
Dispatcher takes appropriate action, such as dispatching another ambulance crew or contacting
the original crew to ensure they are on route
Dispatcher ensures that response times are brought back within established ranges
Dispatcher updates the case record with the actions taken and any changes in status
Extensions:
If the cause of the issue is a delay in dispatch, the Dispatcher contacts the relevant personnel to
investigate and address the issue
If the cause of the issue is an unexpected delay on the part of the Ambulance Crew, the
Dispatcher contacts the crew to ensure that they are on route and taking appropriate action to
reach the patient as quickly as possible
If the cause of the issue is due to external factors, such as a road closure or severe weather, the
Dispatcher may need to make alternative arrangements to ensure that the patient receives timely
care.

Embracing GenAI - A Strategic Imperative
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Operation Blue Star - Saka Neela Tara
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
