Scholarly Resources
Literature reviews
One of the citations used is from Empire State College. This is a
scholarly article, published in an institution of higher learning.
It is helpful in this research since it gives guidelines on how to
arrive at a correct research question. The integrity and quality
of the content are not questionable hence is a good document
for reference (Developing a Research Question, n.d.). The
second citation is obtained from a website of National Institute
of Justice. This article is one of the most helpful because it
gives statistics on the research that was carried out concerning
the research question. This proves that the topic of discussion is
a really important matter that has to be accorded the resources it
deserves in order to fully address it (Recidivism, 2014).
Another source is a book called The Craft of Research, which is
a publication of The University of Chicago Press. It entails the
possible causes of recidivism as the subject matter, dated 2008
(Booth, Williams, & Colomb, 2008). In any research, there are
words that may seem unclear to the researcher hence have to be
looked up in the dictionary. It is true that not every online

13. dictionary or any other book having definitions is scholarly and
worth citing. There are two approved scholarly dictionaries that
have and will be very helpful in this research: Meriam-Webster
(Recidivism, 2015) and the Oxford Dictionaries (Recidivism,
2015).
Further, in the research question we would examine the causes
of the recidivism. We shall as well see the extent, nature, and
the forms that this issue takes. Recidivism in foster care is the
book to look up to (Block & Libowitz, 1983). For comparison
purposes, an article that explains the possible causes of
recidivism by John Dewar is used. It has a well-researched
content that has been cited by many other scholars hence will
give useful information for this research (Gleissner, April, 30th
2012). Kristen Bailey also tries to explain the various acts of
recidivism in his article. Additionally she explains why it is
very needful to address them. Her medical field in which she
practices has given her many experiences regarding the causes
and prevention off criminal behavior in people(Bailey, Dec
2006-Jan 2007).
Mark Gornik in his article reveals ways to reducing recidivism.
He suggests a strategy that involves moving from correctional
programs into better strategies that have been proven to change
the criminal behavior (Gornik). Lastly, an article which
explores incarceration as a way to reducing recidivism presents
us with findings from a research that was undertaken back in the
year 2007 (Mitchell, Wilson, & MacKenzie, 28th September,
2007)

Introduction to Scholarly Writing: Purpose, Audience, and
Evidence
Program Transcript
MALE SPEAKER: We all have experience writing. Emails to
family or friends.
Work memos. Perhaps even a fictional short story or script. As
different as they
may seem, all of these share something in common. They're
written with a
purpose and audience in mind.
Scholarly writing is written with a purpose and audience in
mind as well. But
there is one great distinction. Scholarly writing must include
evidence.
Scholarly writing is material written for a specific purpose to a
specific audience.
It's based on evidence, not assumptions or opinions. It's
objective in tone, and
the writing is clear, concise, and mechanically correct.
Scholarly writing is a way
to demonstrate to your academic audience what you've learned
about a topic.
At Walden University, your audience is comprised of informed
readers with high
expectations, eager to provide you with tools and feedback to
help you learn.

17. They are your faculty, staff, and classmates, and all are
members of the larger
scholarly community. They're critical readers who expect
writers to be objective
with the words they use and the ideas they present.
A challenge new students encounter is the ability to examine
evidence
objectively without making assumptions. Look at this example.
What can we say
about this image from an objective, evidence-based perspective?
It's daytime. The man is wearing a suit. The wedding ring
suggests the woman is
married. She looks approximately 30 years old. They're both
looking at a
computer screen.
Now, use your imagination. Can you make assumptions about
the relationship
between these two people or what they might be doing? Perhaps
he's her boss,
and he's in charge. Or he's teaching her something. Or perhaps
they're
colleagues.
Now, in this next image, does it seem that the woman could be
his boss? Clearly,
we need to know much more to accurately state what's
happening in these
photos. We need evidence.
This is the important task of scholarly writing. Not to take
anything for granted or
to make assumptions, but to use evidence. It's not always easy.
It's natural to

18. bring experience and frame of reference to everything we do.
But successful scholarly writing requires researching and
presenting information
objectively to an academic audience. And the purpose of
scholarly writing is to
©2013 Laureate Education, Inc. 1
Introduction to Scholarly Writing: Purpose, Audience, and
Evidence
uncover and present evidence that will reveal a truth. So
opinion doesn't have a
place in scholarly writing.
But what about extensive personal experience? Does that count

19. toward
producing evidence-based writing? Look at these statements.
Experience can inform your viewpoint and fuel your passion
toward a subject, but
you must remember that experience can also filter your
perspective. So even
with years of professional experience, it's important as a
scholar-practitioner to
remain unbiased, and even to question your own assumptions.
Use only
evidence-based research and dialogue with other scholars to
uncover the
objective truth of your topic.
Finally, scholarly writing requires practice. Remember to keep
your academic
audience in mind, stay focused on the purpose of your writing,
and always use
evidence-based research. Remember to utilize your Walden
faculty and Writing
Center staff as well. They are here to help you. Good luck in
your degree
