Java program I made this Account.java below. Using the attached code I need help with 10.7 (Game: ATM machine) Use the Account class created in Programming Exercise 9.7 to simulate an ATM machine. Create ten accounts in an array with id 0, 1, . . . , 9, and initial balance $100. The system prompts the user to enter an id. If the id is entered incorrectly, ask the user to enter a correct id. Once an id is accepted, the main menu is displayed as shown in the sample run. You can enter a choice 1 for viewing the current balance, 2 for withdrawing money, 3 for depositing money, and 4 for exiting the main menu. Once you exit, the system will prompt for an id again. Thus, once the system starts, it will not stop. */ import java.util.Date; public class Account { /** * @param args */ private int id=0; private double balance=0; private double annualIntrestRate=0; private Date dateCreated; public Account() { super(); } public Account(int id, double balance) { super(); this.id = id; this.balance = balance; } public int getId() { return id; } public void setId(int id) { this.id = id; } public double getBalance() { return balance; } public void setBalance(double balance) { this.balance = balance; } public double getAnnualIntrestRate() { return annualIntrestRate; } public void setAnnualIntrestRate(double annualIntrestRate) { this.annualIntrestRate = annualIntrestRate; } public Date getDateCreated() { return dateCreated; } public void setDateCreated(Date dateCreated) { this.dateCreated = dateCreated; } public double getMonthlyInterestRate() { return (this.getAnnualIntrestRate()/12); } public double getMonthlyInterest() { return (getBalance() *getMonthlyInterestRate()/100); } public double withDraw(double balance) { this.setBalance(this.getBalance()-balance); return this.getBalance(); } public double diposite(double balance) { this.setBalance(this.getBalance()+balance); return this.getBalance(); } public double totalBalance() { balance =balance + getMonthlyInterest(); return balance; } } //AccountTest.java import java.util.Calendar; import java.util.Date; import java.util.Scanner; public class AccountTest { /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub Scanner sc=new Scanner(System.in); Account ac=new Account(1,5000.00); System.out.println(\"Enter the annual intrest rate\"); double intrestRate=sc.nextDouble(); ac.setAnnualIntrestRate(intrestRate); Date d=new Date(); Calendar currentDate = Calendar.getInstance(); ac.setDateCreated(currentDate.getTime()); System.out.println(\"Date id \"+ac.getDateCreated()); System.out.println(\"Monthly intrest rate is :\"+ac.getMonthlyInterestRate()); System.out.println(\"Monthly intrest is :\"+ac.getMonthlyInterest()); System.out.println(\"Enter Amount for diposite \"); double dipositeAmount=sc.nextDouble(); System.out.println(\"The amount after diposite is :\"+ac.diposite(dipositeAmount)); System.out.println(\"Enter Amount to withdraw :\"); double withdramount= sc.nextDouble.

I need help creating a basic and simple Java program. Here is the ex.pdf
I need help creating a basic and simple Java program. Here is the exercise. I have included my
Account class that is referred to at the bottom, below the exercise.
Use the Account class created in Programming Exercise 9.7 to simulate an ATM machine.
Create ten accounts in an array with id 0, 1, . . . , 9, and initial balance $100. The system prompts
the user to enter an id. If the id is entered incorrectly, ask the user to enter a correct id. Once an
id is accepted, the main menu is displayed as shown in the sample run. You can enter a choice 1
for viewing the current balance, 2 for withdrawing money, 3 for depositing money, and 4 for
exiting the main menu. Once you exit, the system will prompt for an id again. Thus, once the
system starts, it will not stop. You will need to cntrl-c to stop your program; this is ok for this
assignment. If you want your program to terminate more elegantly you can add in additional
logic, but this is not required.
Please refer to textbook for sample output pg. 401.

You are not setting any values for those variables(name, ID, interes.pdf
You are not setting any values for those variables(name, ID, interestRate, balance) when you
create the object. Hence, they are instantiated to 0 or null based on the type.
Add this to the main method:
String name = \"Jonathan\"; //any value
int ID = 22; //any value
double interestRate = 10.2; //any value
double balance = 100000.0 //any value
Hence, your final program should look like this:

Why is a 99% condence interval wider than a 95% condence interval?
Solution
confidence intervals are usually expressed with 95% confidence, this is just a tradition.
Confidence intervals can be computed for any desired degree of confidence.
People are often surprised to learn that 99% confidence intervals are wider than 95% intervals,
and 90% intervals are narrower. But this makes perfect sense. If you want more confidence that
an interval contains the true parameter, then the intervals will be wider. If you want to be
100.000% sure that an interval contains the true population, it has to contain every possible value
so be very wide. If you are willing to be only 50% sure that an interval contains the true value,
then it can be much narrower..

What happens when a business is able to segment a market on the basis of needs, but unable to
demographically or behaviorally identify the segments?
Solution
There are four types of segmentation, which are demographic, geographic, psychographic and
behavioral. When a business is able to segment a market on the basis of needs, but unable to
demographically or behaviorally identify the segment, then the business will survive for a short
term only. The business would be able to fulfill the needs of their customers for a shorter span of
time, but it requires proper strategy and segmentation to be done to sustain and be succeed in a
long run..

what is IOT what us
Solution
Ans. IOT stands for Internet of Things: It is a connection of devices over internet to build
applications and services which will serve people needs.
It is a network of applications built over a planned structure to make human lives easy. It can
cover as small a need like an email protocol to as large a need as smart homes. With the advent
of internet and cloud technologies, it has a bright future ahead. It can be extended to army
services too..

What is the major difference between a hub and switch, which one is more efficient at routing
traffic, and which is preferable in larger network configurations?
Solution
The term\' Hub\' usually refers to a piece of network equipment which connects personal
computers together.This type of device carry forwards the information it receives so that it\'s
ports receive the information.Hubs repeat everything they receive and can be used to extend the
network.This can cause unnecessary traffic being send to devices in a network.This kind of
repeating is not a problem in the case of smaller networks but for larger traffic it becomes a
problem so we need to implement another network equipment called switch.
Switches control the netwok traffic by containing the address information of each packet and it
checks to which ports it has to send packets and sends on packets to relevant ports only.This
allows simultaneous communication across switch by improving bandwidth utilisation.
Hubs are used in smaller networks and are used to extend network by providing more number of
ports and switches divide the network into smaller and less blocked sections. Finally switches are
more efficient at routing traffic..
What distinguish between managerial and financial accounting as to (.pdf
What are the similarities between internal and external agents? What are the differences?
Are all consultants change agents? Are all change agents consultants? When does a manager or
leader act as a change agent?
What about change is disruptive? How can meeting the challenge of change becaome
organizational opportunities?
Solution
Internal and external agents have similarities as they both act as change agents and want to bring
necessary change that can improve the organization and the organization can capitalize upon the
new opportunities. Though there are many differences between the internal and external agents.
Internal agents belong to the organization, whereas the external agent is hired as consultant by
the organization. An external agent will be the expertise upon the issues for that he or she is
hired, but an internal agent may not be the expert for the change management. External agent is
hired for a fixed period of time, but internal agent works for indefinitely for the organization.
Consultants are the people who hold expertise in particular areas, so the consultants can be hired
as change agent. But, they may not necessarily be used as change agent. All change agents may
not be consultants as internal resources such as managers and leaders within the organization,
can also act as a change management. When an organization wants to use internal agents for the
change process, then managers and leaders act as change management.
A disruptive change refers to the change in the organizational structure and process that creates
opportunities and make an old structure to be obsolete and irrelevant. Besides, the disruptive
change in fast and quick that unfreeze, redesign and refreeze the organization.
A change management brings the necessary change in the organizational structure and make the
organization to be adaptive to the new market conditions. While doing so, the organization
becomes lean and starts continuous scanning of the market conditions. It helps the organization
to capitalize on new opportunities on offer by the market environment..

The Value Part
Comment on a service organization that provides for you. My favorite is the local hardware
store. They carry a ton of different items. I go in and ask for something and they normally carry
it and will sell me just the amount I need. Home Depot will sell me the item in a 100 unit box
when I only need 10 pieces.
Do service organizations add value to society? Well, according to the MA Dept of Revenue, over
85% of the persons who filed MA Income Taxes, their primary (largest) source of income came
from a service organization. Massachusetts would be in deep trouble financially if there were
only a few service organization were paying wages in this state.
Do you think the US economy needs service organizations?
Solution
With constant technological advancements and the increasing need of producing a steady stream
of revenue from ongoing contracts instead of having a single payment coming from a sold
manufactured product, more and more companies are adapting to the idea of transforming their
age-old traditional manufacturing business to a product-service system. The businesses are now
shifting to a subscription pricing model from the existing lump-sum one-time payment systems.
Talking about the servitisation of products, service industries such as hospitality, retail, banking,
health, information technology, education, etc. focus on service aspect of the business more than
the product aspect. These industries are mass employment providers and heavily invest in their
human capital. Service organisations make use of the skillset, knowledge, experience and talent
of their human resources to produce valuable outcomes for their customers. Whereas,
manufacturing organisations are accused of exploiting depleting natural resources by using them
as raw materials and in return, adversely affects the environment and adding to the prevailing
environmental issues such as pollution and global warming.
The importance of the service organisations in the US economy can be measured by the fact that
in the latest list of Fortune 500 companies, there are more number of service organisations than
number of manufacturers and product-based organisations in comparison to the fortune 500 lists
of past decades. Today, no company can boast of being just a product-based organisation.
Service has become an inseparable component of the product offering. As mentioned in the case,
according to the Massachusetts Department of Revenue, over 85% of the people who filed MA
income taxes had their primary income source coming from a service organisation. This shows
the huge employment opportunities that the service organisations have to offer in the economy.
There is no denying that the relative importance of service is increasing in the product offering of
many organisations. Take the example of IBM that treats its business as a service business
instead of a manufacturing business. Inspite of being in the business of manufacturing of
computers, the management of IBM over .

international market to enter. They are:-
Unrelated diversification is nothing but the diversification when unrelated product lines and new
markets are added to current business. Example- Clothing manufacturer enters into watch
manufacturing business..

Why is a 99% condence interval wider than a 95% condence interval?
Solution
confidence intervals are usually expressed with 95% confidence, this is just a tradition.
Confidence intervals can be computed for any desired degree of confidence.
People are often surprised to learn that 99% confidence intervals are wider than 95% intervals,
and 90% intervals are narrower. But this makes perfect sense. If you want more confidence that
an interval contains the true parameter, then the intervals will be wider. If you want to be
100.000% sure that an interval contains the true population, it has to contain every possible value
so be very wide. If you are willing to be only 50% sure that an interval contains the true value,
then it can be much narrower..

What happens when a business is able to segment a market on the basis of needs, but unable to
demographically or behaviorally identify the segments?
Solution
There are four types of segmentation, which are demographic, geographic, psychographic and
behavioral. When a business is able to segment a market on the basis of needs, but unable to
demographically or behaviorally identify the segment, then the business will survive for a short
term only. The business would be able to fulfill the needs of their customers for a shorter span of
time, but it requires proper strategy and segmentation to be done to sustain and be succeed in a
long run..

what is IOT what us
Solution
Ans. IOT stands for Internet of Things: It is a connection of devices over internet to build
applications and services which will serve people needs.
It is a network of applications built over a planned structure to make human lives easy. It can
cover as small a need like an email protocol to as large a need as smart homes. With the advent
of internet and cloud technologies, it has a bright future ahead. It can be extended to army
services too..
What is the role of capsid and nucleocapsid proteins during the life.pdf
What is the major difference between a hub and switch, which one is more efficient at routing
traffic, and which is preferable in larger network configurations?
Solution
The term\' Hub\' usually refers to a piece of network equipment which connects personal
computers together.This type of device carry forwards the information it receives so that it\'s
ports receive the information.Hubs repeat everything they receive and can be used to extend the
network.This can cause unnecessary traffic being send to devices in a network.This kind of
repeating is not a problem in the case of smaller networks but for larger traffic it becomes a
problem so we need to implement another network equipment called switch.
Switches control the netwok traffic by containing the address information of each packet and it
checks to which ports it has to send packets and sends on packets to relevant ports only.This
allows simultaneous communication across switch by improving bandwidth utilisation.
Hubs are used in smaller networks and are used to extend network by providing more number of
ports and switches divide the network into smaller and less blocked sections. Finally switches are
more efficient at routing traffic..
What distinguish between managerial and financial accounting as to (.pdf
What are the similarities between internal and external agents? What are the differences?
Are all consultants change agents? Are all change agents consultants? When does a manager or
leader act as a change agent?
What about change is disruptive? How can meeting the challenge of change becaome
organizational opportunities?
Solution
Internal and external agents have similarities as they both act as change agents and want to bring
necessary change that can improve the organization and the organization can capitalize upon the
new opportunities. Though there are many differences between the internal and external agents.
Internal agents belong to the organization, whereas the external agent is hired as consultant by
the organization. An external agent will be the expertise upon the issues for that he or she is
hired, but an internal agent may not be the expert for the change management. External agent is
hired for a fixed period of time, but internal agent works for indefinitely for the organization.
Consultants are the people who hold expertise in particular areas, so the consultants can be hired
as change agent. But, they may not necessarily be used as change agent. All change agents may
not be consultants as internal resources such as managers and leaders within the organization,
can also act as a change management. When an organization wants to use internal agents for the
change process, then managers and leaders act as change management.
A disruptive change refers to the change in the organizational structure and process that creates
opportunities and make an old structure to be obsolete and irrelevant. Besides, the disruptive
change in fast and quick that unfreeze, redesign and refreeze the organization.
A change management brings the necessary change in the organizational structure and make the
organization to be adaptive to the new market conditions. While doing so, the organization
becomes lean and starts continuous scanning of the market conditions. It helps the organization
to capitalize on new opportunities on offer by the market environment..

The Value Part
Comment on a service organization that provides for you. My favorite is the local hardware
store. They carry a ton of different items. I go in and ask for something and they normally carry
it and will sell me just the amount I need. Home Depot will sell me the item in a 100 unit box
when I only need 10 pieces.
Do service organizations add value to society? Well, according to the MA Dept of Revenue, over
85% of the persons who filed MA Income Taxes, their primary (largest) source of income came
from a service organization. Massachusetts would be in deep trouble financially if there were
only a few service organization were paying wages in this state.
Do you think the US economy needs service organizations?
Solution
With constant technological advancements and the increasing need of producing a steady stream
of revenue from ongoing contracts instead of having a single payment coming from a sold
manufactured product, more and more companies are adapting to the idea of transforming their
age-old traditional manufacturing business to a product-service system. The businesses are now
shifting to a subscription pricing model from the existing lump-sum one-time payment systems.
Talking about the servitisation of products, service industries such as hospitality, retail, banking,
health, information technology, education, etc. focus on service aspect of the business more than
the product aspect. These industries are mass employment providers and heavily invest in their
human capital. Service organisations make use of the skillset, knowledge, experience and talent
of their human resources to produce valuable outcomes for their customers. Whereas,
manufacturing organisations are accused of exploiting depleting natural resources by using them
as raw materials and in return, adversely affects the environment and adding to the prevailing
environmental issues such as pollution and global warming.
The importance of the service organisations in the US economy can be measured by the fact that
in the latest list of Fortune 500 companies, there are more number of service organisations than
number of manufacturers and product-based organisations in comparison to the fortune 500 lists
of past decades. Today, no company can boast of being just a product-based organisation.
Service has become an inseparable component of the product offering. As mentioned in the case,
according to the Massachusetts Department of Revenue, over 85% of the people who filed MA
income taxes had their primary income source coming from a service organisation. This shows
the huge employment opportunities that the service organisations have to offer in the economy.
There is no denying that the relative importance of service is increasing in the product offering of
many organisations. Take the example of IBM that treats its business as a service business
instead of a manufacturing business. Inspite of being in the business of manufacturing of
computers, the management of IBM over .

Solution
a) according to balanced reaction
4 x 36.5 g HCl reacts with 86.94 g MnO2
43.7 g HCl reacts with 43.7 x 86.94 / 4 x 36.5 = 26.02 g MnO2.
but we have 43.3 g MnO2. so MnO2 present in exess.
limiting reagent = HCl
limiting reagent = HCl
b) 4 x 36.5 g HCl gives 71 g Cl2
43.7 g HCl gives 43.7 x 71 / 4 x 36.5 = 21.25 g
therotical yield of Cl2 = 21.25 g
c) % yield = (actual yield / therotical yield) x 100
76.3 = (actual yield / 21.25) x 100
0.763 = actual yield / 21.25
actual yield = 16.21 g.

wrong. l. Input an integer value altitude and use a loop to write your own graphics program
\'fall.cpp\' that produces a graphic representation of falling object (e.g. circle). An object has
initial downward velocity 0. Each second, it\'s velocity increases by 32 ft/sec Plot the descent of
the falling object. Note that terminal velocity is 174 ft/sec so the object\'s velocity cannot exceed
that speed. Now modify your program to read an integer variable secondstoopen to open a
parachute after n seconds. Assume the velocity decreases by 100 ft/sec after the chute opens until
the downward velocity hits 17 ft/sec. Note that outside the bottom of the loop is the code for

Assuming that the probability for each shot is independent, how many points, on average, can
jenny expect to make when she shoots a one-and-one ( when she only gets a second shot if she
makes the first)?
A. .96
B. 1
C. 2
D. .36

element destroyed the element will be printed to the output. Now add two constructors: the
default one that will create an empty stack, and another one that will receive an integer n and will
build a stack of n elements, such that the first element is 1.0, and the next ones are incremented

In the follwoing double bond hydration reaction: styrene + water (solvent) + H2SO4 (reagent) ---
-> 1-phenylethanol, what role does H2SO4 play?
a. it lowers the energy of activation.
b. it will deprotonate water.
c. it makes the reaction less exothermic.
d. it makest the reaction more exothermic.
I know that H2SO4 in this reaction catalyses the hydration of the double bond, but I do not fully
understand why. I believe the answer is a, but would appreciate correction/and or explanation
from someone with a better grasp of OChem! Thanks :)
Solution
a. it lowers the energy of activation
Once the H+ ion is attacking styrene, it will form a carbocation, it is an intermediate and its
activation energy will be less when campred with the starting material..

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.

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.

The Roman Empire A Historical Colossus.pdf
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
2024.06.01 Introducing a competency framework for languag learning materials ...
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
