Assignment 4:
100 points
due Thurs, Feb 23rd.
Adapt your ArrayOfPokemon code from assignment 2 to use the new Pokemon objects.
When adding a Pokemon, instead of making the user enter all the information, make a menu for
them to pick from the nine (or more) implemented species: (Bulbasaur, Ivysaur, Venusaur,
Charmander, Charmaleon, Charizard, Squirtle, Wartortle, Blastoise).The only thing the user must
choose is the species of Pokemon and if it gets a name.
If they want a name, then the program should ask them to enter one.
Then call the constructor for the chosen Pokemon. For example: Pokemon p = new Bulbasaur();
or Pokemon p = new Squirtle(sName);
Change the Array from assignment 2 to a Java API ArrayList.
For examples on using an ArrayList, see the uploaded sample code ArrayListDemo.java and
slide 40 of ICS211_Lecture09_ListsAndContainers.pdf on Laulima -> Resources -> Week 5.
Also see the Java API website for ArrayList for available methods.
The allowed number of stored Pokemon should still be limited to 6. Don't let the ArrayList keep
growing though it can!

PROGRAM 2 – Fraction Class Problem For this programming as.pdf
PROGRAM 2 – Fraction Class
Problem For this programming assignment, you are to implement the Fraction class design
given below (and discussed in class). You are also to develop an appropriate test driver that
thoroughly tests the class.
Fraction Class Design Implement the following class design. Make sure to use implement the
methods to have the same names as given below, with the same number and types of parameters.
public class Fraction {
private int numer;
private int denom;
// alternate constructor
public Fraction(int numer, int denom)
throws InvalidDenominatorException {
}
// copy constructor
public Fraction(Fraction otherFrac) {
}
// getters
public int getNumer() {
}
public int getDenom() {
}
// standard methods
public String toString() {
}
public boolean equals(Fraction rFrac) {
}
// fraction operators
public Fraction add(Fraction rFrac) {
}
public Fraction sub(Fraction rFrac) {
}
public Fraction mult(Fraction rFrac) {
}
public Fraction div(Fraction rFrac) {
}
public boolean isSimplestForm() {
}
public Fraction reduce() {
}
public boolean properFrac() {
}
public Fraction abs() {
}
public boolean lessThan(Fraction rFrac) {
}
public boolean greaterThan(Fraction rFrac) {
}
public double convertToDecimal() {
}
public Fraction invert() {
}
}
Note that objects of type Fraction are immutable. Also, the alternate constructor throws an
InvalidDenominatorException if passed a denominator value of 0. This exception type is not
predefined in Java, so you must define it as follow as another class in your Java project files:
public class InvalidDenominatorException extends RuntimeException { } // nothing to
implement
This creates an exception of type RuntimeException. RuntimeExceptions do not need to be
caught when thrown. However, your test driver should have the code for catching this exception
where appropriate.
For example, if your test driver excutes the following,
Fraction frac1 = new Fraction(1,2);
then there is no need to catch the possible exception, since it is clear that the denominator is not
0. However, if the value are input by the user, then there is a chance that a denominator vaue of 0
could be entered, and therefore the code for catching the possible exception is needed,
int numer, denom;
Fraction frac1;
Scanner input = new Scanner(System.in);
Boolean valid_input = false;
while (!valid_input) try {
System.out.print(“Enter numerator denominator: “);
numer = input.nextInt();
denom = input.nextInt();
frac1 = new Fraction(numer,denom);
valid_input = true;
}
catch (InvalidDenominatorException e) {
System.out.println(“Denominator of Zero found – Please reenter”);
}
catch (InputMismatchException e) {
System.out.println(“Non-digit character found – Please reenter”);
} etc.
Considerations
Makes sure the equals method returns true for any two fractions that are arithmetically equal.
Make sure that the equals, lessThan and greaterThan methods do not alter the values of the
fractions being compared. You may consider the use of private methods .

Main issues with the following code-Im not sure if its reading the fil.pdf
Main issues with the following code:Im not sure if its reading the file correctly because its
adding all terms together. In other words the the first line of terms is adding the second line of
terms but thats not my intention. Each line of term should have their own polynomial expression
as shown below
Basic specifications :
The code should add the polynomial numbers using a linked list. Java . Keep in mind the
polynomials will be gotten from a file.
Things to keep in mind the list should be in decending order and traverse the list after
all coefficient/exponent pair Term nodes from one input line have been
inserted.
Here are the specifications
//The Polynomial class would likely have a single private data member (reference to
class Term) called head.
//The Term class would likely have three private data
members (coefficient and exponent of type int) and next of type reference to
Term.
//The latter class would also have the following public methods:
constructor(s), gets and sets for each data member, and perhaps a formatting
method with the special output requirements.
An example of input is 7 1 2 4 6 2 -3 2 -1 -1 3
Negative negative
pair signals the termination
***NO doubly linked list , it should be a single linked list **
Input file contains the following :
7 1 2 4 6 2 -3 2 -1 -1 3 ----> 2x^4 - 3x^2 +6x^2 + 7x
5 1 2 3 6 0 -3 2 -1 -1 3 ----> 2*X^3 + (-3)*X^2 + 5*X + 6 // thats the ouput for one line of the
the file , each line of the file should have one polynomial output
Code

// If the polynomial is empty, set the new term as the head
if (head == null) {

} else {
// Traverse the polynomial until we find the correct position for the new term

} else {

PROGRAM 2 – Fraction Class Problem For this programming as.pdf
PROGRAM 2 – Fraction Class
Problem For this programming assignment, you are to implement the Fraction class design
given below (and discussed in class). You are also to develop an appropriate test driver that
thoroughly tests the class.
Fraction Class Design Implement the following class design. Make sure to use implement the
methods to have the same names as given below, with the same number and types of parameters.
public class Fraction {
private int numer;
private int denom;
// alternate constructor
public Fraction(int numer, int denom)
throws InvalidDenominatorException {
}
// copy constructor
public Fraction(Fraction otherFrac) {
}
// getters
public int getNumer() {
}
public int getDenom() {
}
// standard methods
public String toString() {
}
public boolean equals(Fraction rFrac) {
}
// fraction operators
public Fraction add(Fraction rFrac) {
}
public Fraction sub(Fraction rFrac) {
}
public Fraction mult(Fraction rFrac) {
}
public Fraction div(Fraction rFrac) {
}
public boolean isSimplestForm() {
}
public Fraction reduce() {
}
public boolean properFrac() {
}
public Fraction abs() {
}
public boolean lessThan(Fraction rFrac) {
}
public boolean greaterThan(Fraction rFrac) {
}
public double convertToDecimal() {
}
public Fraction invert() {
}
}
Note that objects of type Fraction are immutable. Also, the alternate constructor throws an
InvalidDenominatorException if passed a denominator value of 0. This exception type is not
predefined in Java, so you must define it as follow as another class in your Java project files:
public class InvalidDenominatorException extends RuntimeException { } // nothing to
implement
This creates an exception of type RuntimeException. RuntimeExceptions do not need to be
caught when thrown. However, your test driver should have the code for catching this exception
where appropriate.
For example, if your test driver excutes the following,
Fraction frac1 = new Fraction(1,2);
then there is no need to catch the possible exception, since it is clear that the denominator is not
0. However, if the value are input by the user, then there is a chance that a denominator vaue of 0
could be entered, and therefore the code for catching the possible exception is needed,
int numer, denom;
Fraction frac1;
Scanner input = new Scanner(System.in);
Boolean valid_input = false;
while (!valid_input) try {
System.out.print(“Enter numerator denominator: “);
numer = input.nextInt();
denom = input.nextInt();
frac1 = new Fraction(numer,denom);
valid_input = true;
}
catch (InvalidDenominatorException e) {
System.out.println(“Denominator of Zero found – Please reenter”);
}
catch (InputMismatchException e) {
System.out.println(“Non-digit character found – Please reenter”);
} etc.
Considerations
Makes sure the equals method returns true for any two fractions that are arithmetically equal.
Make sure that the equals, lessThan and greaterThan methods do not alter the values of the
fractions being compared. You may consider the use of private methods .

Main issues with the following code-Im not sure if its reading the fil.pdf
Main issues with the following code:Im not sure if its reading the file correctly because its
adding all terms together. In other words the the first line of terms is adding the second line of
terms but thats not my intention. Each line of term should have their own polynomial expression
as shown below
Basic specifications :
The code should add the polynomial numbers using a linked list. Java . Keep in mind the
polynomials will be gotten from a file.
Things to keep in mind the list should be in decending order and traverse the list after
all coefficient/exponent pair Term nodes from one input line have been
inserted.
Here are the specifications
//The Polynomial class would likely have a single private data member (reference to
class Term) called head.
//The Term class would likely have three private data
members (coefficient and exponent of type int) and next of type reference to
Term.
//The latter class would also have the following public methods:
constructor(s), gets and sets for each data member, and perhaps a formatting
method with the special output requirements.
An example of input is 7 1 2 4 6 2 -3 2 -1 -1 3
Negative negative
pair signals the termination
***NO doubly linked list , it should be a single linked list **
Input file contains the following :
7 1 2 4 6 2 -3 2 -1 -1 3 ----> 2x^4 - 3x^2 +6x^2 + 7x
5 1 2 3 6 0 -3 2 -1 -1 3 ----> 2*X^3 + (-3)*X^2 + 5*X + 6 // thats the ouput for one line of the
the file , each line of the file should have one polynomial output
Code
import java.io.File;
import java.io.FileNotFoundException;

public class Polynomial {
private Term head;

public Polynomial() {
head = null;
}
// Method for adding a term to the polynomial, this is inside the polynomial term
public void addTerm(int coefficient, int exponent) {
// Create a new term object
Term newTerm = new Term(coefficient, exponent);
// If the polynomial is empty, set the new term as the head
if (head == null) {
head = newTerm;
} else {
// Traverse the polynomial until we find the correct position for the new term
Term current = head;
Term previous = null;
while (current != null && current.getExponent() > exponent) {
previous = current;
current = current.getNext();
}
// If a term with the same exponent already exists, add the coefficients
if (current != null && current.getExponent() == exponent) {
current.setCoefficient(current.getCoefficient() + coefficient);
} else {
// Otherwise, insert the new term into the polynomial
if (previous == null) {
head = newTerm;
} else {
previous.setNext(newTerm);
}
newTerm.setNext(current);
}
}

Stopping Player
All players need to stay within the eld boundaries. This rst class you write will lay some of the
foundation for the logic needed in all your players. Create a class called Stopping that extends
the Player class. A Stopping player will initially move in a random direction and stops moving
when it reaches the border of the playing eld (without leaving the playing eld). The direction that
a player moves in is determined by its speed in each direction: speedX and speedY. You will add
this logic to manipulate the speed attributes for stopping in its play() method. Take care to notice
that the images of the players have some size to them. Your player should not “visually” leave
the eld. All parts of the image should be on or inside the eld boundaries.

Here are the instructions and then the code in a sec.
**Please Resubmit the revised and updated Code (GamerService) with Comments added
explaining please. RIGHT***** JAVA. HOWEVER IF YOU NEED TO CHANGE THE
ENTIRE THING IT IS FINE. I AM DESPERATE.
Part II. Java Application: Use the code you submitted in Project One Milestone to continue
developing the game application in this project. Be sure to correct errors and incorporate
feedback before submitting Project One.
Please note: The starter code for this project was provided in the Project One Milestone. If you
have not completed the Project One Milestone, you will not be penalized in this assignment, but
you will have additional steps to complete to ensure you meet all the components of Project One.
Review the class files provided and complete the following tasks to create a functional game
application that meets your clients requirements. You will submit the completed game
application code for review.
Begin by reviewing the base Entity class. It contains the attributes id and name, implying that all
entities in the application will have an identifier and name.
Software Design Patterns: Review the GameService class. Notice the static variables holding the
next identifier to be assigned for game id, team id, and player id.
Referring back to Project One Milestone, be sure that you use the singleton pattern to adapt an
ordinary class, so only one instance of the GameService class can exist in memory at any given
time. This can be accomplished by creating unique identifiers for each instance of a game, team,
or player.
Your client has requested that the game and team names be unique to allow users to check
whether a name is in use when choosing a team name. Referring back to the Project One
Milestone, be sure that you use the iterator pattern to complete the addGame() and getGame()
methods.
Create a base class called Entity. The Entity class must hold the common attributes and
behaviors (as shown in the UML diagram provided in the Supporting Materials section below).
Refactor the Game class to inherit from this new Entity class.
Complete the code for the Player and Team classes. Each class must derive from the Entity class,
as demonstrated in the UML diagram.
Every team and player must have a unique name by searching for the supplied name prior to
adding the new instance. Use the iterator pattern in the addTeam() and addPlayer() methods.
Functionality and Best Practices
Once you are finished coding, use the main() method provided in the ProgramDriver class to run
and test the game application to ensure it is functioning properly.
Be sure your code demonstrates industry standard best practices to enhance the readability of
your code, including appropriate naming conventions and in-line comments that describe the
functionality.
Here is my answer that I need a little improvement on its code since I am having trouble making
it right.
Here I am attaching code for these Files:

Repeat Programming Project 2 in Chapter 5. This time, add the following four constructor
methods: one for each instance variable, one with two parameters for the two instance variables,

one true or false case for each of the test method.

Your client has requested that the game and team names be unique to allow users to check
whether a name is in use when choosing a team name. Referring back to the Project One
Milestone, be sure that you use the iterator pattern to complete the addGame() and getGame()
methods.
Create a base class called Entity. The Entity class must hold the common attributes and
behaviors (as shown in the UML diagram provided in the Supporting Materials section below).
Refactor the Game class to inherit from this new Entity class.
Complete the code for the Player and Team classes. Each class must derive from the Entity class,
as demonstrated in the UML diagram.
Every team and player must have a unique name by searching for the supplied name prior to
adding the new instance. Use the iterator pattern in the addTeam() and addPlayer() methods.
Functionality and Best Practices
Once you are finished coding, use the main() method provided in the ProgramDriver class to run
and test the game application to ensure it is functioning properly.
Be sure your code demonstrates industry standard best practices to enhance the readability of
your code, including appropriate naming conventions and in-line comments that describe the
functionality.
Here is my answer that I need a little improvement on its code since I am having trouble making
it right.
Here I am attaching code for these Files:

Stopping Player
All players need to stay within the eld boundaries. This rst class you write will lay some of the
foundation for the logic needed in all your players. Create a class called Stopping that extends
the Player class. A Stopping player will initially move in a random direction and stops moving
when it reaches the border of the playing eld (without leaving the playing eld). The direction that
a player moves in is determined by its speed in each direction: speedX and speedY. You will add
this logic to manipulate the speed attributes for stopping in its play() method. Take care to notice
that the images of the players have some size to them. Your player should not “visually” leave
the eld. All parts of the image should be on or inside the eld boundaries.

Here are the instructions and then the code in a sec.
**Please Resubmit the revised and updated Code (GamerService) with Comments added
explaining please. RIGHT***** JAVA. HOWEVER IF YOU NEED TO CHANGE THE
ENTIRE THING IT IS FINE. I AM DESPERATE.
Part II. Java Application: Use the code you submitted in Project One Milestone to continue
developing the game application in this project. Be sure to correct errors and incorporate
feedback before submitting Project One.
Please note: The starter code for this project was provided in the Project One Milestone. If you
have not completed the Project One Milestone, you will not be penalized in this assignment, but
you will have additional steps to complete to ensure you meet all the components of Project One.
Review the class files provided and complete the following tasks to create a functional game
application that meets your clients requirements. You will submit the completed game
application code for review.
Begin by reviewing the base Entity class. It contains the attributes id and name, implying that all
entities in the application will have an identifier and name.
Software Design Patterns: Review the GameService class. Notice the static variables holding the
next identifier to be assigned for game id, team id, and player id.
Referring back to Project One Milestone, be sure that you use the singleton pattern to adapt an
ordinary class, so only one instance of the GameService class can exist in memory at any given
time. This can be accomplished by creating unique identifiers for each instance of a game, team,
or player.
Your client has requested that the game and team names be unique to allow users to check
whether a name is in use when choosing a team name. Referring back to the Project One
Milestone, be sure that you use the iterator pattern to complete the addGame() and getGame()
methods.
Create a base class called Entity. The Entity class must hold the common attributes and
behaviors (as shown in the UML diagram provided in the Supporting Materials section below).
Refactor the Game class to inherit from this new Entity class.
Complete the code for the Player and Team classes. Each class must derive from the Entity class,
as demonstrated in the UML diagram.
Every team and player must have a unique name by searching for the supplied name prior to
adding the new instance. Use the iterator pattern in the addTeam() and addPlayer() methods.
Functionality and Best Practices
Once you are finished coding, use the main() method provided in the ProgramDriver class to run
and test the game application to ensure it is functioning properly.
Be sure your code demonstrates industry standard best practices to enhance the readability of
your code, including appropriate naming conventions and in-line comments that describe the
functionality.
Here is my answer that I need a little improvement on its code since I am having trouble making
it right.

Repeat Programming Project 2 in Chapter 5. This time, add the following four constructor
methods: one for each instance variable, one with two parameters for the two instance variables,

one true or false case for each of the test method.

Milestone, be sure that you use the iterator pattern to complete the addGame() and getGame()
methods.
Create a base class called Entity. The Entity class must hold the common attributes and
behaviors (as shown in the UML diagram provided in the Supporting Materials section below).
Refactor the Game class to inherit from this new Entity class.
Complete the code for the Player and Team classes. Each class must derive from the Entity class,
as demonstrated in the UML diagram.
Every team and player must have a unique name by searching for the supplied name prior to
adding the new instance. Use the iterator pattern in the addTeam() and addPlayer() methods.
Functionality and Best Practices
Once you are finished coding, use the main() method provided in the ProgramDriver class to run
and test the game application to ensure it is functioning properly.
Be sure your code demonstrates industry standard best practices to enhance the readability of
your code, including appropriate naming conventions and in-line comments that describe the
functionality.

What is the role of civil society in promoting democracySolutio.pdf
What is the role of civil society in promoting democracy?
Solution
1) Civil society can limit and control the power of the state. A country must need a way to keep
the power of political leaders in check or control.
2) Civil society exposes the corrupt officials and government bodies. Even though the anti-
corruption laws exists but for them to function effectively active participation of civil society is
required.
3) NGOs can educate people about their fundamental rights given by the constitution.
4) Civil societies can be training platforms for future leader.
5) Civil societies also play a vital role in the monitoring the conduct of elections. They make sure
that the POLL takes place without any manipulations of the machines at polling station..
What mechanism causes plant ion-uptake to acidify soilSolution.pdf
What mechanism causes plant ion-uptake to acidify soil?
Solution
Answer=
The mechanisms that causes plant ion uptake to acidify soil=
soil acidification is a natural process in high rainfall environments
major nutrient fertilizers such as nitrogen is major nutrient affecting soil pH
there are 3 mechanisms
1] root interception = it is physical contact resulted by root growth
2] Mass flow= involves the transport of nutrients to the root as a result of transpiration
3] diffusion movement= caused by differences in concentration
nutrients are taken up by roots which dominant in nutrition or by leaves is only additional in
nutrition.
using the knowledge about experiments that are related to plant g.pdf
using the knowledge about experiments that are related to plant growth including those done by
fritz went to answer the questions above a) What was the HYPOTHESIS that went wanted to
answer (2ptsy? b) How did Went test his hypothesis (Pictures are ok as long as there are words
explaining the picture) (4ptsy! c) What was the final RESULT of Went\'s experiment (2pts)?
Solution
Cholodony- Went model decribes tropism in emerging shoots of monocotyledons, including the
tendencies of the shoot to grow towards light ( phototropism) and the roots towards downward
position ( Gravitropism).
In both the cases the directional growth is considered to be due to asymmetrical distribution of
Auxin, a plant hormone.
The rate of growth depends on the concentration of the auxin and both gravity and unidirectional
light effect the movement of auxin.
Basic Model: cholodony and went proposed that auxin is synthesised in the coleoptile tip which
senses light and sends the auxin down the shady side of the coleoptile.
Later experiments showed that auxin moved from a source along a horizontal coleoptile section,
concentrating along the bottom of the section and causing the shoot to bend upward.
The model was later extended to Gravitropism of roots where auxin was thought to inhibit rather
than stimulate growth and to accumulate in the lower side of the root section causing the root to
bend.
Result of Cholodony Went Model: Both phototropism and gravitropism is due to the
asymmetrical distribution of hormone auxin. The rate of growth is dependent on concentration of
auxin and both gravity and unidirectional light effect the movement of auxin..
True or False Justify your answer.The concept of flooding is alwa.pdf
True or False? Justify your answer.
The concept of flooding is always a bad idea for routing IP packets.
Solution
TRUE.
Because flooding can be costly in terms of wasted bandwidth. While a message may only
have one destination it has to be sent to every host. In the case of a ping flood or a denial of
service attack, it can be harmful to the reliability of a computer network. Furthermore messages
can become duplicated in the network further increasing the load on the networks bandwidth as
well as requiring an increase in processing complexity to disregard duplicate messages.
Duplicate packets may circulate forever, unless certain precautions are taken:.
True or False. If H is a subgroup of the group G then H is one of it.pdf
True or False. If H is a subgroup of the group G then H is one of its cosets in G. Every
subgroup of a group G is normal. If |H|
Solution
a) True as He=H where e is identity element.
b) False, only the subgroup N satistfying the property gng^-1 in N for every n in N and g in G(
group) are normal.
but if group is abelian then every subgroup is normal.
c) True, as K contain more elements than H it has more subgroups.
d) False, For two distinct cosest identity elements belongs to only one cosets because distinct
cosets for set of equivalance classes.
e) yes for each positive integer n we have group for that number.
f) false, because it is only true only if G has order of prime power (sylow thm).

Question 11 Scarcity means O people need to use marginal analysis to make choices O options
are restricted O opportunity costs arise O all of the above
Solution
Answer is All the above.
Explanation:
Scarcity means limited available resources and allocation of these resources need to be made
based on marginal analysis of various options available. These options are restricted based on
limited resources. The resources put in one option must have an opportunity cost of foregoing the
next best option..
Question 2 Sba Do you know something about the Statement Of Financ.pdf
Question 2 Sba: \"Do you know something about the Statement Of Financial Position (SOFP)?
Don: \"What\'s that?\" Sba: The SOFP is actually not a part of the double entry system. Don:
\"Are you sure? But when I close the ledgers, its balances are all shown in the SOFP Sha: \"Yup,
I am pretty sure. Did you forget that the SOFP doesn\'t have closing balances?\" Don: \"Oh
yeah.... Required: Based on the above conversation, discuss on the implications in which the
Statement Of Financial Position (SOFP) not being part of the double entry system. (3 marks)
Solution
EXPLANATION --- First of all lets discuss what is Statement of Financial position?? It is
basically a statement showing the financial position of an individual or any entity or organisation
at the end of end at a particular date. It is none other than BALANCE SHEET. It is made up of 3
things -- LIABILITIES , ASSETS and EQUITY.
It helps stakeholders and users of financial statements to assess the financial soundness of an
entity in terms of liquidity risk, financial risk, credit risk and business risk.
Now lets discuss whether statement of financial position is part of double entry system or not ??
No , it is a part of double entry system as it shows the total balances of assets, liabilities and
equity at a particular given date. As double entry system affects two ledgers at a single
transaction so balance sheet is also dependent upon double entry book system.Therefore, Yes
Balance Sheet (accounts) are also a part of the double entry system, however it is not mandatory
to have a balance sheet account in each and every double entry transaction..

List and explain all the components of company culture.Jackson, S..pdf
List and explain all the components of company culture.
Jackson, S. E., Schuler, R. S., & Werner, S. (2012). Managing Human Resources (11th ed.).
Cengage Learning
Solution
Building a company culture of engaged employees takes years and requires consistent execution.
I boiled down our culture strategy into 10 essential components I call the \"10 Cs of Culture.\"
1. Core Values
I used to be very cynical about \"core values.\" I thought these were just mottos written on
plaques hanging on the wall. But when we implemented our values strategy at Beryl about 10
years ago, I began to see how they guided everyday decision-making and how employees
referenced them in meetings. I came to realize they are essential guideposts when developed,
communicated, and executed in a consistent manner. Values are those behaviors that will never
change no matter how the company changes. Today, our values are not only painted on the
walls, but also discussed from the first day an employee joins Beryl. We start every big meeting
with a conversation about values and tell stories about how our coworkers live by those values
on a daily basis.
2. Camaraderie
Camaraderie is about having fun. It\'s about getting to know colleagues not just as colleagues,
but what they\'re like outside the office. To do that, Beryl hosts dress-up days, parties, games,
and events all the time. We have annual traditions like family day, the Gong show, March
Madness, the fall festival, and a holiday party. We include not only employees, but also their
families. We publish a bi-monthly full-color magazine called Beryl Life that is sent to the homes
of co-workers. Kids of our employees compete to design the t-shirt for our annual family day
and families even participate in our talent show
3. Celebrations
You can\'t underestimate the importance of recognizing your team. While it may be important
for your people to hear from the CEO, it also feels great for them to hear from peers. At Beryl,
we developed a program we call PRIDE (Peers Recognizing Individual Deeds of
Excellence). This allows coworkers to recognize others for living up to Beryl\'s core values. We
also have quarterly contests for people who have received PRIDE certificates. We go out of our
way to celebrate personal successes too, like baby showers, sports accomplishments, or
educational milestones.
4. Community
Part of the fabric of a successful company culture is connecting with and giving back to the local
community. Even though Beryl is a national company serving national customers, we have
dedicated countless hours to community service in Bedford, Texas (where Beryl is based) to help
those in need. This not only helps the organization\'s Beryl support, but brings great pride to
staffers.
5. Communication
At Beryl, I encourage formal and informal communication consistently and at all levels of the
company. I hold quarterly Town Hall meetings, which includes six meetings over two days. This
is a challenge since Beryl is a 24-hour .
Please write 5-6 setences about each emotional intelligence capabili.pdf
Please write 5-6 setences about each emotional intelligence capabilities (with the traits). This is a
part of my paper. Please help!
Self-Awareness – with the traits: Emotional Self-Awareness, Accurate Self-Assessment, and
Self-Confidence.
Self-Management – with the traits: Self-Control, Trustworthiness, Conscientiousness,
Adaptability, Achievement Orientation, and Initiative.
Social Awareness – with the traits: Empathy, Organizational Awareness, and Service Orientation
Social Skill – with the traits: Visionary Leadership, Influence, Developing Others,
Communication, Change Catalyst, Conflict Management, Building Bonds and
Teamwork/Collaboration.
Solution
Self-Awareness
Self awareness is the quality to understand oneself through various self assessment activities,
awareness can be defined as the knowledge to distinguish between right and wrong, therefore
self awareness generally means the individual ability to make one\'s self aware about any aspect.
Self confidence plays a huge role in this context because self confidence helps a person to
believe in himself and do the right things to be successful it is closely related with self awareness
because if a person is not aware of certain things then it is difficult to apply the learning\'s and
knowledge. Self awareness is influenced by the emotional qualities that each and every
individual possess and it is very much necessary for the emotional growth of the individual as
well.
Self Management
It can be stated that no individual can be successful without the quality of self management
because each and every individual needs to manage himself in various points of life without
which success will not be achieved. Control is the most important aspect here because the
individual should possess proper control of all the emotions be it anything and he should also be
well aware of his actions too. The individual needs to possess the quality of adaptation because
without proper adaptation it will be difficult for him to cope with various situations that will
come his way. Achievement should not impact much and change the person because no
achievement is too big or too small he should learn from the mistakes and the achievements
which will help him grow as a human being.
Social Awareness
There are some social responsibilities that each and every individual should be responsible
enough to execute because without that the individual becomes socially inactive. The individual
should judge each and every situation by keeping himself in the situation of the other person or
group and empathize the situation while taking a decision or stand. As conveyed there are some
social responsibilities as well as organizational responsibilities that each and every organization
expects from its employees and the individual should abide by them. This is a very important
trait that individuals should possess in order to be socially active and aware.
Social Skill
A soft skill which an employer is always looking in his employee b.

Negligence and intentional torts are subject to civil litigation as .pdf
Negligence and intentional torts are subject to civil litigation as opposed to criminal litigation.
However, should a person who commits a civil tort like battery, also be prosecuted criminally?
Some famous examples of criminal defendants who were prosecuted civilly as well as criminally
are OJ Simpson and Bernard Madoff. How was it possible for OJ Simpson to be acquitted in the
criminal case but found liable for wrongful death in the civil case?
Solution
Intentional tort such as battery is two dimensional in nature. If they are not severe they can be
treated as civil wrong and are handled as a civil lawsuit for demand of compensation as monetary
damages.
However, if they are severe and are result of the criminal intent of the person they will be
considered a crime and can lead to prosecution by the state under criminal laws. In the case of
the OJ Simpson he was acquitted because the plaintiff failed to prove the presence of death by
criminal intent. But he was responsible for the death as even if there is no criminal intent one can
be found responsible under various civil theories such as negligence etc..

Identify major groupings within the Lophotrochozoa and Ecdy gg g soz.pdf
Identify major groupings within the Lophotrochozoa and Ecdy gg g sozoa ; describe
distinguishing features among groups, where on Earth these organisms are typically found, and
how they make a living
Solution
Lophotrochozoa are a group or taxon of protostome animals. The taxon consists of 2 groups-
trochozoans and lophophorata. Trochozoans are characterized by the development of mouth
before anus in the embryo.They are worm like and produce trochophore larvae - larvae that have
2 bands of cilia around their middle. Lophophorata, on the other hand, are grouped by the
presence of lophophore characterized by a fan of ciliated tentacles surrounding their mouths.
These animals exhibit radial cleavage.
Lophotrochophora includes the following phyla
1. Phylum Ectoprocta:
These are mostly marine coelomates that use lophophore for feesing. They secrete and live in
zoecium (chitinous chamber).
2. Phylum platyhelminthes
These are mostly parasitic acoelomates. Some may live as scavengers or commensals. The are
flat and ribbon-shaped. They have an incomplete gut, no circulatory system, and a simple
nervous system. Their excretory system has small tubules lined with ciliated flame cells. They
are hermaphrodites.
3. Phylum Rotifera
These are small aquatic pseudocoelomate animals. They are mostly free living and a few are
paraitic. They have a ciliated food gathering organ at the tip of the head known as corona. They
have jaws in the pharynx and their digestive system has separate mouth and anus. They have
rudimentary circulatory system and they have separate sexes.
4. Phylum Annelida
They are segmented coelomates with a closed circulatory system. Their excretory system
includes nephrida. They have a digestive system with separate mouth and anus. Gas exchange is
through skin.They have setae. They are found in both terrestrial and aquatic habitats. They can
be parasites, carnivores, predators or scavengers.
5. Phylum Nemertea
They are partially coelomate and partially acoelomate animals. They are free living and possess
proboscis - a long muscular tube covered by a sheath to capture prey. They have a complete
digestive system, a simple nervous system, and a closed circulatory system.
6. Phylum Phoronida:
They are coelomate and marine. They use lophophore for feeding. They have a U-shaped gut and
they secrete and live in a chitinous tube.
7. Phylum Brachipoda:
They are characterized by the presence of 2 calcified shells.
Ecdysozoa also belons to the group of protostome animals characterized by a three layered
cuticle which is periodically molted,a process known as ecdysis. They lack locomotary cilia.
They produce amoeboid sperm. Their embryos donot undergo spiral cleavage unlike other
protostomes.
The group includes
Phylum arthropoda
The phylum includes invertebrate animals with an exoskeleton. They have jointed limbs and
their cuticle is made of chitin. They are segmented with an open circulatory system and a ladder-
like nervous system They are found in both a.

ABSTRACT -
This paper \"breaks out of the box\" by discussing the work of the artist Andy Warhol as a form
of consumer research. The paper asserts that Warhol’s career- successful artist, experimental
filmmaker, prolific writer and diarist, celebrity-offers insights into consumer culture that
reinforces, expands, and illuminates aspects of traditional consumer research. Through
illustrations, criticism, and interpretation, five specific areas of consumer research that Warhol’s
work might contribute to are introduced: brand equity; clothing, fashion and beauty; imagery;
packaging; and self-concept. This project joins recent efforts by consumer researchers to include
humanities based methods such as literary criticism and semiotics into the consumer researcher’s
toolbox.
I love America and these are some comments on it. The image is a statement of the symbols of
the harsh impersonal products and brash materialistic objects on which America is built today. It
is a projection of everything that can be bought and sold, the practical but important symbols that
sustain us.
- Warhol 1985, p. 78
Humanities based research has changed the parameters of consumer research. Groundbreaking
applications of semiotics (Mick 1986), literary theory (Stern 1988; 1989) postmodernism (Firat
and Venkatesh 1995), history (Jones and Monieson 1990), visual studies (Scott 1994)to- name a
few-have broadened the consumer researcher’s alette, adding useful tools to an interdisciplinary
paintbox. Belk proposes that art offers a useful medium to study consumption-citing literature,
comics, painting, photography, etc., as valuable records of materialism and non-traditional
sources of data for consumer researchers (Belk, 1986). Art and science do differ in their
methods, biases, and purposes, Belk insists, but there is much more overlap than is usually
thought. He concludes by suggesting that uses of art in research \"are attempts to draw on art as
data for evidence to validate a point or to provide a thicker, richer description\" (Belk, 1986, p.
27).
This paper proposes that Andy Warhol-through his worldwide success as an artist, his choice of
subject matter, his public statements, and his marketing techniques-may offer insights into
several issues of consumer research as an additional way of learning about consumer behavior
(Belk, Wallendorf, and Sherry 1989; Hudson and Ozanne 1988; Sherry 1991). Through a turn to
the tools of art criticism and art history, Warhol’s \"contributions\" to our understanding of
consumer behavior are placed within the frame of consumer research. Warhol, while not trained
in experimental methods, nonetheless offers unique insights into consumer behavior through his
success as an artist who focused on the mass produced world of brand names, fame, and
consumption.
In his career as a commercial illustrator, artist, filmmaker, and author, Warhol produced a
voluminous output of ma.

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.

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.

A Strategic Approach: GenAI in Education
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.

ArrayListOfObjectsAssignment 4100 pointsdue Thurs, Feb 23rd..pdf
- 1. ArrayListOfObjects Assignment 4: 100 points due Thurs, Feb 23rd. Adapt your ArrayOfPokemon code from assignment 2 to use the new Pokemon objects. When adding a Pokemon, instead of making the user enter all the information, make a menu for them to pick from the nine (or more) implemented species: (Bulbasaur, Ivysaur, Venusaur, Charmander, Charmaleon, Charizard, Squirtle, Wartortle, Blastoise).The only thing the user must choose is the species of Pokemon and if it gets a name. If they want a name, then the program should ask them to enter one. Then call the constructor for the chosen Pokemon. For example: Pokemon p = new Bulbasaur(); or Pokemon p = new Squirtle(sName); Change the Array from assignment 2 to a Java API ArrayList. For examples on using an ArrayList, see the uploaded sample code ArrayListDemo.java and slide 40 of ICS211_Lecture09_ListsAndContainers.pdf on Laulima -> Resources -> Week 5. Also see the Java API website for ArrayList for available methods. The allowed number of stored Pokemon should still be limited to 6. Don't let the ArrayList keep growing though it can! Assignment 2 code is here,Please help me change it to match Assignment 4's requirement. This is the Pokemon.java code.import java.util.*; //scannerpublic class PokeArray{static final int SIZE = 6;public static void main(String[] args){Scanner userIn = new Scanner(System.in);String inString = new String("");boolean endLoop = false;Pokemon[] arrPoke = new Pokemon[SIZE];int nextIndex = 0; //points to index for next insert//loop until stopping condition is givenwhile(endLoop != true){//menu textSystem.out.println("Please enter the number of your choice:");System.out.println("1.
