The World's Most Popular Spice

Recognized as the world’s most popular spice, pepper was once so rare and valuable; it was sometimes used as currency. A major commodity in Europe during the Middle Ages, pepper was not only used as a seasoning, but also as a preservative and as a medicine.

Televisions and Obesity

A more recent study found that children who watch more than three hours of television a day are 50 percent more likely to be obese than kids who watch fewer than two hours. These researchers conclude that more than 60 percent of overweight incidents can be linked to excess TV viewing (Temblay, 2003).

Obesity puts children at risk for a variety of health problems. Type II diabetes, or adult onset, is closely connected to weight. One study found that rates of this disease in children quadrupled, rising from 4 percent in 1982, to 16 percent by 1994 (Squires, 1998)

Uses for the Dash

The dash is a legitimate and effective mark of punctuation when used according to accepted conventions. As an emphatic punctuation mark, however, the dash loses effectiveness when it is overused. In typewritten or simple word processing-generated material, a dash is formed by typing two hyphens with no space before, between, or after the hyphens. In printed or desktop publishing-generated material, a dash appears as a solid line (an em dash) Here are suggestions for and illustrations of appropriate uses of the dash.

1. To Set Off Parenthetical Elements
Within a sentence, parenthetical elements are usually set off by commas. If, however, the parenthetical element itself contains internal commas, use dashes (or parentheses) to set it off.

Sources of raw materials-farming, mining, fishing, and forestry- are all dependent on energy.
Four administrative assistants-Priscilla Alvarez, Jaja Daprosa, Joseph Yuga, and Edward Tan-received cash bonuses for outstanding performance in their departments.


2. To Indicate an Interruption.
An interruption or abrupt change of thought may be separated from the rest of a sentence by a dash.

The shipment will be on its way-you have my word-by Wednesday.
Send the disks by Friday-no, we must have them sooner.

Sentences with abrupt changes of thought or with appended afterthoughts can usually be improved through rewriting.

3. To Set off a Summarizing Statement
Use a dash (not a colon) to separate an introductory list from a summarizing statement.

Variety of tasks, contact with people, opportunity for advancement-these are what I seek in a job.
Running, playing tennis, and reading-those are Bill's favorite pastimes.

4. To Attribute a Quotation
Place a dash between a quotation and its source.
