T he Progressive Movement encompassed a variety of different ideas and activities of reformist

In the play Julius Caesar, the author Shakespeare depicts a persistent controversy between Caesar and
his conspirators that turned against Caesar. Brutus remained a great friendship with Caesar for a very
long time until he became a disguised rival that was joined by many other conspirators which involved
Cassius. Through many struggles and schemes, they achieved their goal to bring Caesar down and
assassinated him when the chance was given. E Tu Brute? were the last words of Caesar that left a

He uses the technique of ethos for the citizens to be convinced that what Brutus had done was for the
good of the citizens. In the speech, Brutus quotes Believe me for mine honor, and have respect to mine
honor that you may believe(III.II. 15 16) , he uses his credibility to provide evidence to the crowd. He
plays a significant role in the Senate, which he is honored. Using this advantage, he persuades people
to believe him that what he does is for their own good and that he would not lie as he is known to be
an honored man. Using ethos, people fell into the trap of believing Brutus and his reasoning very
quickly. However, Antony uses ethos to get the audience s support and it was a very dangerous
moment for Antony as he had to indirectly attack Brutus. Antony uses ethos by supporting Brutus so
that the citizens will believe Antony and his credibility will be able to bring the audience to understand
that what Brutus had done was just part of the conspiracy. In the quote Which all the while ran blood,
great Caesar fell. O, what a fall was there, my countrymen!(III.II. 201 202) , Antony uses the name of
Julius Caesar as a way to bring together the people of Rome. He uses the authority of Caesar to raise
his values and commemorate him and his great leadership he owned. The word fall used in this quote
has two meaning; the first being that he fell as he was assassinated and the second meaning used in

one is considered villainous? How many innocent civilians can one harm without becoming the very
monster being fought against? Moore and Gibbons were using the Watchmen not as a case for the

Ulrich and says, Death and damnation to you, Ulrich Von Gradwitz , as they were trapped under the

some of the arguments against the policy, I would like to clarify one or two points of information
which might be of interest. The half caste people were half aboriginal and half European. These were
the people which the policy affected the most. At the time, Australia had another policy called the
white Australia policy. This stated that any person who was not of a European race was not allowed to
live in Australia. This policy was in action until the 1960s. Aboriginals were not treated as citizens of
Australia. Although they abided by the countries rules, they were not allowed to take an active part in
society by doing things like voting in elections. Arguments Against the Policy I am now going to state
some of the arguments against the stolen generation policy . Taking children away from their parents
is a very immoral thing to do. It harms the emotional health of both the parents and the children.

by sexual contact, men and women should adhere to strict guidelines to prevent transmission of the
virus. The CDC advise men that traveled or resided in an active zika infected area, the men should
avoid having sexual contact with the spouse or use latex condoms during any sexual contact.
Individuals that are exposed to the zika virus should not donate blood. In the environmental efforts, all
efforts to remove mosquitos breeding sites are encouraged. For example, buckets and pots should be

Newspaper Comparison
Today s society is in many respects dominated by the media. Newspapers, books, television, radio and
the Internet not only play significant role in an average person s life but are also multi billion pound
industries that, through the public exposure they are subject to, carry great influence. One of the oldest
media formats still in use is the newspaper. This old printed format carries great political power and
boasts huge readerships, partly due to its cheap price, never exceeding a few pounds an issue, and its
portability.
Throughout the decades during which Newspapers have developed, two main styles of writing and

However, tabloids are generally considered to be the more sensationalist, emotionally concerned and
subjective newspapers containing more pictures and easy to read text (such as the Sun and the Mirror).
Typically, Many Tabloid only require a reading age of 9, thus allowing them to be readily understood
by the less well educated and intellectual members of the public. Clearly, the properties of these
formats can be seen as direct opposites. However they do share some similarities. An obvious
common property of all newspapers is that they are commercial, that is, that they will try to appeal to a
large a readership as possible, within their market niche readership and this is reflected in their range
of content and style. Some newspapers try to appeal to more people by mixing elements of tabloids
and broadsheets (such as the Daily Mail and the Daily Express), although the large tabloid and
broadsheet newspapers tend to follow the traditional stereotypical styles for their type. The other key
similarity between each type of newspaper is that they all exist to report the news and current affairs,

SEZ...Special Economic Zone...why are they special?
Well to start with SEZs have always emerged a matter of conflict between the industrialists and the
land owners. Debates regarding their status, policies and even existence have always drawn their

In 1965 the India adopted the earliest versions of SEZ as export oriented zones called Export
Processing Zone by setting up Asia s first EPZ in Kandla. This was a step to boost the economy by
allowing to work outside the clutches of poor infrastructure and controlled policies. It was to draw
foreign investments and give the much needed growth to the economy. However, it did not receive
much of an attention due lack of clarity on policies and other difficulties.

This initiative is expected to bring greater economic prosperity to the nation and expand the growth

However, most of the time there is a controversy with regards to land issues involved in SEZs.
Conversion of agricultural land to industrial hubs is a matter of debate. The positive argument is that
land is necessary and every possible effort should be made to gather large lands for industry to add to
growth, but the negative argument it that industry should be set up on lands which are not suitable for
agriculture.
Whether or not a landowner gets the right to compensation is even a bigger question. The farmers are
given alternative means of living and whether they can adapt to it is a matter of debate again.

The only concern within aviation was the safety of flying. Hardly any thought was put into the
security sector of the aviation industry. This changed when Peruvian revolutionaries took over a Pan
American mail plane. In the period of time from 1930 to 1958, there was 23 hijackings reported. The
first serious incident happened in 1947 when the aircrew member was killed. In 1955, Jack Graham,
placed a bomb in his mother s luggage. The bomb exploded during the flight killing all aboard. A
similar incident took place in 1960, when two suicide bomber killed all people on a board. After these
acts luggage inspection has become more exact. The majority of hijackings were made due to either
escape from the USA or hold people for a ransom. In 1961, in order to prevent hijackings, the federal
government started using armed guards on chosen aircrafts. After hijackings of planes in 1969 the

24. The Negative Effects Of Peer Pressure On College Students
The four short years that people spend in college can be some of the best years of their lives. Meeting
new people, learning new things, and getting involved in clubs all contribute to this. Although these
years can be great, they also have the ability to damage our lives forever. Many students fall victim to
peer pressure, which occurs when a person or certain group of people tries to force an individual to
conform to how that person or group acts. Peer pressure can affect college students physically,
mentally, and socially. I feel as though this issue should be addressed much more when it comes to
college life. Peer pressure is not a new occurrence that has only come to light within the last few
years. It has happened since the beginning of time, whether it be within friend groups, within the
workplace, or within school settings. The idea of peer pressure is already negatively viewed by many
people, and rightfully so. Many people feel as though they need to fit in with a group, so they fall
victim to peer pressure. This is especially true for freshman college students, who feel as though they
need to do certain things and act a certain way to fit in (Palmeri [1]). These social pressures make
them do things they usually did not do. The two most obvious things that students may fall into due to
peer pressure is alcohol and drug use. These are two substances that are almost always causing harm

Södergran pushed to get through with the growth objectives on his first meeting. I think that Alvarez is
a good friend of Costas whom he sees as reliable business partner. There are two following
alternatives for Södergran:

King Philip the II was an absolute monarch who centralized the government of Spain. Before the reign

The medieval era was a time where was was given away to the greedy hands of many, but only to
those who desired it for a urge of evil desire. The monarchy who once was the way of the people was
belittled, and almost no more. Even though they had a say for the law, they used this power for the
tyrannical abuse of religious affairs, and persecuted thousands not following in the ways of
christianity. The darkness that once swept across the kingdom of Spain was pushed back by a man of
logistic perspective. King Philip II was a man who led his country to a golden age, furthering his
people to push advancements forwards and enhance their way of living. Philip took the nobles by
storm, and contained their greedy ways by showing his absolutism views of how a monarchy should
rule the land. Although Philip II did so much for his country, he shallowly let his kingdom perish
through hard debt and taxes as well as his inherited way of persecuting religious innocents. Before the
reign of King Philip the II the land was distraught and wounded as well as many other kingdoms along

It was quite understood that it was only Noah and his family that was rescued from the earth including
some selected animals. Those animals overpowered man and men were praying, calling upon God to
intervene in their situation. They made a decree that whosoever will be a powerful man should come

of phosphates, limestone, marble, and arable land. As of 2011 their total renewable water resources are
14.7 cu km, with total withdrawals in 2005 only at 0.17 cu km per year, suggesting they have enough
water resources to meet the growing needs of their people for the time being. The percentage of

32. Art Form Of Music
Music is art form that doubles up as a form of expression. Depending on where you are from and or
where you live the music that is readily available will vary. For example, the most popular genres
around where I live go from country music to rap and hip hop. One of the biggest factors of how
music is developed is the cultural background that it comes from. Ancient tribal societies have used
music as a foundation for gatherings and to express history. In reality, music has been around for
thousands of years and people were expressing it way before the 21st century.
Music helps define character and allows self expression in a more unique matter. For instance, folk
music, this type of music originates in traditional popular culture and is typically of unknown
authorship. Most rap artists nowadays write about drugs and making money but others are just using it

raps about real life problems and what s going on around him in the city where he s from. To people
who don t live in the ghetto or a poverty struck area, living in the hood isn t as bad as it seems, but for

ratio between peaks from each sample demonstrated a poly crystal structure. Also, no clear
preferential growth direction could be observed for each sample. The peaks of all Co doped films were
very close to the pure iron pyrite peaks. No clear peak shift could be observed. This indicated that
shallow cobalt doping had little impact on the crystal structure of FeS2.

As more electrons were introduced, the net carrier concentration started to decrease until the electrons
became the majority carriers. This process may explain the change of conduction type and carrier
concentrations. The carrier mobility, however, decreased gradually from 6.52 cm2/V*s to 4.30
cm2/V*s as cobalt doping increased from 2 at% to 6 at%. This phenomenon could be explained as the
decreased mean free path of charged carriers because of the larger size of the incorporated cobalt ions
than the original iron ions. After switching to n type, the increasing carrier concentration may also
contributed to the reducing of carrier mobility. As a consequence, cobalt doping served well as an n
type dopant after 3 at% doping level.
