Draft Introduction
The topic selected is "Media's Influence on public perceptions
and attitudes about immigrants." The media is responsible for

9. reporting accurate information to the general public. The main
goal is not only to present information but also to encourage
society to take part in solving various social-economic and
political issues. So many people can easily access information
since the modern mass media platforms such as television and
radio replaced traditional forms of communication. However,
the information presented to the public is not always accurate
thus misleading society, (Haynes, et.al., 2016). In today's
society, the media has a significant influence on society thus
can easily shape public perceptions and attitudes.
Immigrants are just as human as any other person in the world.
However, the media has influenced society to label and consider
them less human. For instance, the terms “undocumented” and
“illegal” are often used by the media when reporting about
immigrants in various parts of the world. The media realizes its
power to influence yet still promotes negative perceptions and
attitudes in society. This is a failure in the media’s part to
uphold work ethics that ensure accurate reporting. As a result,
many immigrants are subjected to discrimination and hate based
on the information that the media has presented to society,
(Kosho, 2016).
Research is necessary to identify how the media misreports
information to influence public opinions and attitudes about
immigrants. Some of the questions that should be answered in
the study include; How does the media misreport to portray a
bad image for immigrants? How does the media collaborate with
various individuals or organizations to negatively influence
society about immigrants? How can the media prioritize the
immigrants’ opinions, challenges, and needs when reporting to
society? The media’s role in influencing negative attitudes
about immigrants in society is worth investigating, (Figueroa-
Caballero & Mastro, 2019).

This article highlights the role of media in reporting and
associating immigrants with undesired behavior in American
society. The author captures the media’s role in supporting a
political ideology that discriminates immigrants. The Trump
administration is so far the most critical government in dealing
with immigration. According to this article, news coverage
about Latino immigrants often misrepresents reality thus
influencing society negatively. This article serves as a reliable
source of information about the topic of study.

https://doi.org/10.1080/03637751.2018.1505049
This article highlights how the media misreports about
immigrants and links them to criminal behavior in society. The
authors conclude that there is no meaningful link between crime
and undocumented crime as the media often reports. However,
the media often headlines cases that involve undocumented
immigrants engaged in criminal behavior intending to portray
them as criminal masterminds. As such, this article offers
meaningful insights about the media’s role in branding
immigrants as criminals.

According to this article, the media influences public
perceptions and attitudes about immigrants by misreporting. The
authors highlight how the media intentionally manipulate

11. semantics to influence public perceptions of immigrants. The
article describes how the media uses terms like "undocumented"
and "illegal" to negatively portray immigrants to society. This
article offers reliable information to support the argument made
for the proposed study; the media influences negative public
perceptions about immigrants.

In this article, the author highlights how the lenses of media
shape public perceptions and attitudes in today's society.
According to the author, the media wields great power to
influence the public about issues such as immigration. The
article suggests that the media collaborates with politicians and
organizations to support the implementation of strict
immigration policies by misreporting about immigrants.
Therefore, this article is a reliable source of information about
the proposed study.

Guidelines for the Term paper:
I am scaling back your term paper assignment this semester.
Instead of 8 to 10 pages total, I would like the body of your
literature review (not counting title page and reference list) to
be 4 to 5 pages. You’ve written a proposal and received my
feedback on it, but here is some more detail about my
expectations for the finished product.
Overall expectations
· All writing should be your own. Any word-for-word phrases
that come from other sources will be inside quotation marks and
properly cited. Any ideas that come from other sources should
be cited, too. All papers will be checked with TurnItIn
plagiarism detection.
· Sources should generally be academic research – long, with a
big list of sources at the end. (A few exceptions can be made for
news sources that report up-to-date information, such as the
percentage of Americans online.)
· Every paper should have a page that lists its references in
APA style (if you need help, a quick online guide is available
at https://owl.english.purdue.edu/owl/resource/560/01/ (Links to
an external site.)).
· You must submit an electronic copy through Canvas.
· It is worth 400 points, or 20% of your grade.
The literature review
· A well-researched general literature review integrates and
presents what is known about a topic. You report on the
research and writings of others, and you cite them
appropriately. (A different kind of literature review makes an

13. argument or offers a rationale for a set of hypotheses or
research questions that your study goes on to examine with
empirical data. You may well write that kind for your capstone
project.)
· You will want to demonstrate an understanding of your topic
and round up the best research on it.
· Usually it’s best to organize the paper around areas within the
topic. A history of how African-Americans have been
represented could follow a historical organization, from earliest
representations to modern ones. A discussion of the effects of
media violence might be organized around the different effects
(fright, mean world perceptions, aggressive behavior, etc.).
· Integration of your sources is important. Use the sources
together to make points (or counterpoints); show how they
comment on each other. I don’t want a paper that reads like a
bunch of unconnected abstracts.
· I will expect a minimum of 8 sources. These should be high-
quality academic sources. And you should cite all of them in a
way that shows how they contribute to our understanding of
your topic.
Response for the proposal：
Intro 70/80
Good topic idea. You also seem focused not just on media but
on news media specifically, and your focus includes effects on
public opinion. This is a good scope for work. Topics might
include immigration in the U.S. as well as the refugee crisis in
Europe mainly from Syria.
You make some assumptions about how media broadly speaking
report on immigration. You will find there are many different
frames that media (in following their sources) may use. This is
not so much a question of accuracy but rather of focus. That
said, frames that focus on specific crimes that immigrants have
committed suggest an inaccurate association between
immigrants and crime; most research finds crime rates for
immigrants (including undocumented ones) are lower than for

14. native citizens.
(The term “undocumented” is not generally considered an anti-
immigrant term such as “illegals” or worse, “wetbacks.” In
some ways, it is a technical term; some might even consider it a
euphemism.)
Source quality 25/30
You have three high quality sources (two articles in reputable
journals and a book from an academic publisher). One of your
sources was published in the “INTERNATIONAL JOURNAL
OF SCIENTIFIC & TECHNOLOGY RESEARCH,” which is
known as a predatory journal. That means the journal accepts
every submission, no matter how poor, and authors pay to have
their work published. In looking at it myself, the article is very
brief, not well written, and reports no original research.
Source relevance 28/30
All sources seem very much linked to the question of how
media represent immigrants and what effects that has on public
opinion about immigrants.
Summaries 45/60
The summaries sometimes don’t sound much like their sources.
For instance, Chattopadhyay (2019) does not find the media (in
this case just 35 stories from the New York Times)
“misrepresent reality.” (This article seems to assume the NYT’s
reporting accurately reflects, for instance, changes in the types
of migrants and changes in U.S. policy).
It is important to focus on research findings. For instance,
Figueroa-Caballero and Mastro (2018) find that reports of crime
done by illegal immigrants leads to greater in-group
identification and more negative attitudes toward immigration
and, in turn, support for harsher crime sentencing. You describe
Haynes et al (2016) as an article. It is a book.
