Modify your program code for the JavaMenus.java file such that the program will include
a new menu item. To do this alter the menu component items scheme to appear as follows.
Open Item
A Graphic image appears drawn out in the Frame
New Item
A historical quote appears in the Frame along with a corresponding image related to the quote.
Example- picture of Steve Jobs along with a Jobs quote of sorts.
Edit Item
A message box appears with the user’s name.
Exit Item
The application exits.
Test your modified program.
STEP 5 Supplement the Program Code
Modify again your program code for the JavaMenus.java file such that the program will
include a new second column of menu items. To do this alter the menu bar such that it
will contain these items.
Welcome Item
A message box appears that describes the program.
About Item
A message box appears with your name, as the programmer and version number of the app.
Open Item
A Graphic image appears drawn out in the Frame
New Item
A historical quote appears in the Frame along with a corresponding image related to the quote.
Example- picture of Steve Jobs along with a Jobs quote of sorts.
Edit Item
A message box appears with the user’s name.
Exit Item
The application exits.

How can I make the add button and remove button initialize button work?
For the buttons should add and remove to the JTextArea and JList.
when you write you use the JTextField to add or remove what you write in the JTextArea and
JList.
For the initialize, the button should initialize the text once.
Ihave three class.

Take Note These questions requires diagrams.Scenario Sweetbriar .pdf
Take Note: These questions requires diagrams.
Scenario: Sweetbriar College is redesigning their course registration system [CRS]. They plan
for this system to be web-based, but first you need to model the main system behind the web
interface. Here is a description of the interactions with the proposed CRS.
Faculty enter courses into the system, assign section numbers, instructors, dates, times, and
classrooms for individual instances of a course. Students can browse available course-sections.
Students or faculty advisors can register students for course-sections. Faculty can view a class
list and enter grades for a course-section they are teaching. Students can view their course
schedule and their grades for individual courses. The Registrar\'s office can view a student\'s
history of courses and grades.
1. Using our Sweetbriar College scenario, evolve your Object Class Diagram for the CRS into
design packages. Include packages for the Human Computer Interface [HCI] layer, the
application layer, and the data management [DM] layer.
2. Expand the application layer package for the CRS. Include packages for Faculty and Staff,
Students, and Courses.
3.Expand the HCI layer package for the CRS. Include packages for Faculty and Staff interface,
and Student interface.
Create a Sequence Diagram for \'Student Registers for Course-Section\' for questions 4 and 5
4.Expand the Sequence Diagram you developed for \'Student Registers for Course-Section\' so
that it includes the objects from the HCI layer and the DM layer.
5.Expand the Sequence Diagram you developed for \'Faculty Creates New Course-Section\' so
that it includes the objects from the HCI layer and the DM layer.

Take Note These questions requires diagrams.Scenario Sweetbriar .pdf
Take Note: These questions requires diagrams.
Scenario: Sweetbriar College is redesigning their course registration system [CRS]. They plan
for this system to be web-based, but first you need to model the main system behind the web
interface. Here is a description of the interactions with the proposed CRS.
Faculty enter courses into the system, assign section numbers, instructors, dates, times, and
classrooms for individual instances of a course. Students can browse available course-sections.
Students or faculty advisors can register students for course-sections. Faculty can view a class
list and enter grades for a course-section they are teaching. Students can view their course
schedule and their grades for individual courses. The Registrar\'s office can view a student\'s
history of courses and grades.
1. Using our Sweetbriar College scenario, evolve your Object Class Diagram for the CRS into
design packages. Include packages for the Human Computer Interface [HCI] layer, the
application layer, and the data management [DM] layer.
2. Expand the application layer package for the CRS. Include packages for Faculty and Staff,
Students, and Courses.
3.Expand the HCI layer package for the CRS. Include packages for Faculty and Staff interface,
and Student interface.
Create a Sequence Diagram for \'Student Registers for Course-Section\' for questions 4 and 5
4.Expand the Sequence Diagram you developed for \'Student Registers for Course-Section\' so
that it includes the objects from the HCI layer and the DM layer.
5.Expand the Sequence Diagram you developed for \'Faculty Creates New Course-Section\' so
that it includes the objects from the HCI layer and the DM layer.

How do i add a file menu to my java programSolutionHere goes .pdf
Here is the answer, I just want to know how people find it step by step (6) Find all asymptotes (if
any) f (r) In 2a 3) g(a) h (ar) 2-3
Solution
f(x)=ln(2x-3)
To find the vertical asymptote we have to set 2x-3to zero
2x-3=0
X=3/2
g(x)= (x3-9x)/(x4+3x3+2x2)
= (x)(x+3)(x-3)/(x2)(x+1)(x+2)
=(x+3)(x-3)/x(x+2)(x+1)
Vertical asymtote
x(x+2)(x+1)=0
x=-2,-1,0
Horizontal asymtote
Since the degree of numerator is less than the degree of denominator. Therefore horizontal
asymptote is y=0
h(x)=2-3x+1
Here the constant is the horizontal asymptote which is 2.Hence the horizontal asymptote y=2.

Java questionI am having issues returning the score sort in numeri.pdf
Java question
I am having issues returning the score sort in numerical order for more than 2 entries. I had to
develop an enhancement which allowed the application to sort the list by score. The easiest
solution is probably to create a second student class (perhaps called StudentScore) that
implements the IComparable interface to sort by score rather than by name
StudentSortApp
import java.util.*;
public class StudentSortApp
{
public static void main(String[] args)
{
System.out.println(\"Welcome to the Student Scores Application.\"+\"\ \");
Scanner sc = new Scanner(System.in);
System.out.print(\"Enter number of students to enter: \");
int numberofStudents = sc.nextInt();
//arrays storing student name and score
Student[] students = new Student[numberofStudents];
StudentScore [] studentScores = new StudentScore [numberofStudents];
int t = 0;
for (int i = 0; i < numberofStudents; i++)
{
System.out.println(\"\");
String studentLastName = Validator.lastName(sc, \"Student \" + (i+1) + \" Last name: \");
String studentFirstName = Validator.lastName(sc, \"Student \" + (i+1) + \" First name: \");
int studentScore = Validator.validScore(sc, \"Student \" + (i+1) + \" score : \");
students [t] = new Student(studentFirstName, studentLastName , studentScore);
studentScores [t] = new StudentScore(studentFirstName, studentLastName , studentScore);
t = t + 1;
}
//output
System.out.println(\"\");
System.out.println(\"Last Name Sort\");
Arrays.sort(students, 0, numberofStudents);
for(Student i: students)
System.out.println(i.getlastName()+\", \"+i.getfirstName()+\": \"+i.getScore());
System.out.println();
System.out.println(\"Score Sort\");
Arrays.sort(studentScores, 0, numberofStudents);
for(StudentScore i: studentScores)
System.out.println(i.getlastName()+\", \"+i.getfirstName()+\": \"+i.getScore());
}
}
Validator Class
import java.util.Scanner;
public class Validator
{
public static int validScore(Scanner sc, String prompt)
{
int studentScore = 0;
boolean isValid = false;
while (isValid == false)
{
System.out.print (prompt);
studentScore = sc.nextInt();
if (studentScore > 100 || studentScore < 0)
{
System.out.println(\"Error! You have to enter a score between 0 and 100\");
}
else
{
isValid = true;
}
}
return studentScore;
}
public static String lastName(Scanner sc, String prompt)
{
Scanner input = new Scanner(System.in);
String StudentName = \"\";
boolean isvalid = false;
while (isvalid == false)
{
System.out.print (prompt);
StudentName = input.nextLine();
if (StudentName == null || StudentName.equals(\"\"))
{
System.out.println(\"Error! You have to enter a name.\");
}
else
{
isvalid = true;
}
}
return StudentName;
}
}
Student Class
public class Student implements Comparable
{
private String firstName = \"\";
private String lastName = \"\";
private int score = 0;
// Student Class constructor
public Student(String firstName, String lastName, int score)
{
this.firstName = firstName;
this.lastName = lastName;
this.score = score;
}
@Override
public int compareTo.

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:.

Note
This application will adds only 3 students data.And Dislpay those 3 students data.
I just modified some code which rectifies your problem.Thank You

How do i add a file menu to my java programSolutionHere goes .pdf
Here is the answer, I just want to know how people find it step by step (6) Find all asymptotes (if
any) f (r) In 2a 3) g(a) h (ar) 2-3
Solution
f(x)=ln(2x-3)
To find the vertical asymptote we have to set 2x-3to zero
2x-3=0
X=3/2
g(x)= (x3-9x)/(x4+3x3+2x2)
= (x)(x+3)(x-3)/(x2)(x+1)(x+2)
=(x+3)(x-3)/x(x+2)(x+1)
Vertical asymtote
x(x+2)(x+1)=0
x=-2,-1,0
Horizontal asymtote
Since the degree of numerator is less than the degree of denominator. Therefore horizontal
asymptote is y=0
h(x)=2-3x+1
Here the constant is the horizontal asymptote which is 2.Hence the horizontal asymptote y=2.
Write a GUI application to simulate writing out a check. The value o.pdf
Use a power series to approximate the definite integral,I, to six decimal places.
Solution
(x^3)/(1 + x^4) = (x^3)*(1 + x^4)^-1 = (x^3)*(1 - x^4 + x^8 + . . . using the
binomial formula. (I doubt whether any more is necessary.) INT [0, 0.2] (x^3)/(1 + x^4) dx =
INT [0, 0.2] x^3 - x^7 + x^11 - . . . = (1/4)x^4 - (1/8)x^8 + (1/12)x^12 - . . . = (1/4)*0.2^4 -
(1/8)*0.2^8 + (1/12)*0.2^12 - . . . = 0.000399680 =0.000400 (6 dec. pl.).

Java questionI am having issues returning the score sort in numeri.pdf
Java question
I am having issues returning the score sort in numerical order for more than 2 entries. I had to
develop an enhancement which allowed the application to sort the list by score. The easiest
solution is probably to create a second student class (perhaps called StudentScore) that
implements the IComparable interface to sort by score rather than by name
StudentSortApp
import java.util.*;
public class StudentSortApp
{
public static void main(String[] args)
{
System.out.println(\"Welcome to the Student Scores Application.\"+\"\ \");
Scanner sc = new Scanner(System.in);
System.out.print(\"Enter number of students to enter: \");
int numberofStudents = sc.nextInt();
//arrays storing student name and score
Student[] students = new Student[numberofStudents];
StudentScore [] studentScores = new StudentScore [numberofStudents];
int t = 0;
for (int i = 0; i < numberofStudents; i++)
{
System.out.println(\"\");
String studentLastName = Validator.lastName(sc, \"Student \" + (i+1) + \" Last name: \");
String studentFirstName = Validator.lastName(sc, \"Student \" + (i+1) + \" First name: \");
int studentScore = Validator.validScore(sc, \"Student \" + (i+1) + \" score : \");
students [t] = new Student(studentFirstName, studentLastName , studentScore);
studentScores [t] = new StudentScore(studentFirstName, studentLastName , studentScore);
t = t + 1;
}
//output
System.out.println(\"\");
System.out.println(\"Last Name Sort\");

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).

next best option..
Question 2 Sba Do you know something about the Statement Of Financ.pdf

\"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

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.

How does Warhol add to the semiotic statement of the readymade?
Solution
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.

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.

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.
