DiKsa [7]

Answer:

Explanation:

ecause of their unique perspective, Americans fear globalization less than anyone else, and as a consequence they think about it less than anyone else. When Americans do think about globalization, they think of the global economy as an enlarged version of the American economy.

(Source: Thurow, L. (1993). Fortune Favors the Bold (p. 6). New York: Harper Collins.)

According to Lester Thurow (1993) Americans fear globalization less than people from other countries and as a consequence spend less time thinking about it. Indeed, Americans see globalization as an enlarged version of their own economy.  

Why is this plagiarism?

The writer has used Thurow's exact words without enclosing them in quotation marks. S/he has only substituted synonyms here and there. Even though Thurow is credited with a citation, this would be considered plagiarism.

Lester Thurow (1993) maintains that because Americans see globalization simply as a bigger form of their own economy, they are less concerned about it than is the rest of the world.

Why is this acceptable?

The writer has kept the meaning of the original passage without copying words or structure. Words like globalization and Americans are generic terms (i.e., terms that are commonly used for the concept they illustrate - it is difficult to find synonyms for them). Thus you may use these words without placing them in quotation marks.

(Complete Thurow reference appears in bibliography)

What strategies can I use to paraphrase?

Use synonyms for all words that are not generic. Words like world, food, or science are so basic to our vocabulary that is difficult to find a synonym.

Change the structure of the sentence.

Change the voice from active to passive and vice versa.    

Change clauses to phrases and vice versa.

Change parts of speech.

Acceptable Paraphrase #1

Acceptable Paraphrase #2

Like drought, excess rainfall and flooding can also contribute to epidemics of waterborne infectious diseases, in this case due to poor sanitation resulting from runoff from overwhelmed sewage lines or the contamination of water by livestock.

(Source:  Shuman, E., M.D. (2010, March 25). Global climate change and infectious diseases.  New England Journal of Medicine; 362, 12, 1061-1063. Retrieved from nejm.org at MIT Libraries.)

Used Synonyms

An overabundance of rainfall can also be a factor in spreading infectious diseases carried by water, usually as a result of overflowing sewers and pollution from farm animals (Shuman, 2010).

Changed Sentence Structure

When there is an overabundance of rainfall, two situations can occur: sewers can overflow and water can become polluted by the presence of livestock, both of which can lead to outbreaks of waterborne diseases (Shuman, 2010).

Example 2

Original Acceptable Paraphrase

Current political and economic incentives favor industry and other interest groups at the expense of health: consider the subsidies paid for corn-based agriculture and mass-produced processed foods, the tobacco revenue generated in countries with a government-owned tobacco industry, industrial growth in the face of environmental pollution, and the spread of the sedentary automobile-and-television culture.

(Source:  Venkat Narayan, K.M., Ali, M.K., and Koplan, J.  (2010, September 23).  Global noncomunicable diseases – where worlds meet. The New England Journal of Medicine, 363; 13. 1196-1198. Retrieved from nejm.org at MIT Libraries.)

Changed Voice and Changed Parts of Speech

Researchers point out that in attempting to implement economic growth, industry is often favored over health: government may subsidize certain forms of agriculture and food production, contribute to tobacco consumption in nations where it owns the industry and otherwise promote growth of industries that pollute. (Venkat Narayan et. al, 2011).
