Directional Measurements
Time, Rate and Distance
When working with time, rate and distance problems the most important thing is to keep the units of measurement the same.
If the rate is in miles per hour then the distance needs to be miles and the time needs to be hours. If anything is not the same it should be converted.
FORMULAS:
Distance= rate x time
Rate= distance/time
Time= distance/rate
Speed, velocity, acceleration, g-force and momentum
Speed and velocity are different. Speed measures how fast something is going while velocity indicates its direction. Acceleration measures how quickly something speeds and g-force is an acceleration measure. The “g” represents the normal force of gravity. Momentum is the force needed to stop an b=object in motion.
FORMULAS AND EXAMPLES:
Acceleration=(ending velocity – starting velocity)/time
If a car accelerates from s=zero to 60 in 30 seconds what is the rate of acceleration?
(60 mph – 0 mph)/30 seconds = 2mph per second
Momentum= mass x velocity
What was the momentum of a race car weighing 132 kilograms when it crashed into a wall if it traveling 150 mph?
Convert mph to kilometers per hour (kph): 105 mph x 1.6= 168kph
132 kilograms x 168 kph= 22,176 kilogram kilometers per hour
Area Measurements
Journalists can use area measurements in all different types of stories. It is useful for a journalist to know how to calculate perimeter when writing articles about new developments or construction projects. Area is also important for real estate, technical, feature and sports reports. Square feet and square yards are useful when checking reports on size and circumference and radius are important for dealing with stories on circular area.
FORMULAS:
Perimeter = (2 x length) + (2 x width)
Area (squares and rectangles) = length x width
Area (triangles) = .5 base x height
Circumference = 2P x radius
Area (circles) = 2P x (radius)^2
Volume Measurements
In the business world terms like ton, barrel, box and cord take on a specific meaning. Goods are often sold in volumes. A goods measurement can vary based on the market, knowing how to measure volume is a key component to selling any good.
Liquid Volume
Liquid measurements apply to liquids in recipes, bodies of water and other fluids.
EXAMPLES:
2 tablespoons = 1 fluid once
4 quarts = 1 gallon
1 U.S. standard barrel = 31.5 gallons
For finding the volume of a rectangular solid use this formula: Volume = length x width x height
Other measurements:
Cord: 128 cubic feet
Ton:
Short ton= 2,000 lbs
Long ton= 2,240 lbs
Metric ton= 2,204.62 lbs
The Metric System
Most Americans struggle to use the metric system yet the rest of the world uses it for every type of measurement. The metric system is an important tool for international commerce. It is based on the multiples of 10.
Definitions
Meter: basic unit for length
Mass: derived from meter and the unit for weight
Newton: unit of force
Basics
Because the metric system is based on the decimal system you can change from one unit to another simply by multiplying or dividing by any multiple of ten. Each unit is ten times as large as the next unit.
Prefixes can create larger or smaller factors when added to a unit name. The prefixes for numerical values are:
micro (1 millionth) 0.000001
milli (1 thousandth) 0.001
centi (1 hundredth) 0.01
deci (1 tenth) 0.1
no prefix 10
deka 10
hecto 100
kilo 1,000
mega 1,000,000
giga 1,000,000,000
tera 1,000,000,000,000

A behind the scenes look at Elon’s presidential office with Lisa Keegan
By Patrick McCabe
Written May 2, 2009
Have you ever wondered who oversees all of Dr. Lambert’s appointments? Or who ensures that he is prepared for the daily grind of being a college president?
Meet Lisa Keegan, the senior assistant to the president and secretary to the board of trustees. Keegan received her bachelor of science in business administration with a concentration in finance from Elon and than attended law school at Stetson University.
“I went to law school thinking that I wanted to do work for child advocacy in the legal field,” said Keegan. “But in my second year of law school I took a course called law and higher education policy and for me it was that moment where light
bulbs were going off where I thought this is what I want to do. I want to get back into higher education.”
Keegan returned to Elon with her soon to be husband John and fell into her current position.
“For me to find a position where I could follow the career path I wanted and be at the school that I love, it was just a perfect match,” said Keegan.
Keegan’s duties as senior assistant to the president and secretary to the board of trustees include overseeing Dr. Lambert’s calendar, serving as the liaison between the president and the board of trustees, is responsible for setting and organizing the platform party for all major speakers that come to campus and other duties that vary on a daily basis.
“My job varies everyday and that is one thing I love about my job,” said Keegan. “We always have very nice to do list but we never get to it all day because new things come up everyday.”
Keegan’s job is constantly changing and she never knows what will await her when she arrives in the morning or returns from lunch.
“One thing that I do love about it is that it changes on a daily basis. There is something new everyday,” said Keegan. “I knew that this job was going to be something different within the first month when I returned from lunch and asked my colleague if anything happened while I was gone? She responded with ‘yes well we got a call from Hillary Clinton’s Campaign and Bill Clinton is going to be on campus next week’ and I thought okay well this is going to be a very different position.”
Keegan has limited direct interaction with students but that is something she wants to change. In addition to the Elon 101 course she will be teaching next year she will be working very closely with junior Noelle Clemente. Noelle serves as the current office assistant for graduate admissions and will serve as the office assistant to the president’s office next fall. The two have already begun preparing for the busy fall that awaits Dr. Lambert.
“I’ve been helping her run errands and tried to assist her with any early preparation that I can,” said Clemente.
While she has only known her for a limited time Noelle has had many interactions with Keegan through her work in graduate admissions.
“Lisa’s presence provides that Elon spirit of a friendly, caring genuine person,” said Clemente. “Everything she does she does with the students interests in mind.”
Like students Keegan has also taken the opportunity to learn while here at Elon. Her position and the people around her have taught her a lot.
“Sometimes I feel guilty,” said Keegan. “I feel like I am getting more than I am giving to the position because I have been learning so much just through observation.”
While Keegan loves her current position she hopes that one day she will be working in a higher position within an upper education administration.
“I see myself in a University setting and I truly hope it is still at Elon,” said Keegan. This place is ever changing and ever transforming and it is something that is amazing to be a part of. I hope I am in an administrative position but I can’t say where.”
Keegan continues to serve the president, the board of trustees and the students and offers them this piece of advice.
“The best life advice I ever received is from my grandfather, I would always share with him everything I was involved in and everything I was doing and he would always say ‘none of it matters unless you’re having fun.’ I try to remember that on my most stressful days.”

Math Tools for Journalists: Chapters 5-8
How a journalist should analyze polls, surveys, business, stocks and bonds and property taxes.
By Patrick McCabe
No one, not even journalists can escape the math world. Math is a great tool for a journalist to present cold hard facts using numbers and journalists use a variety of math tools in their pieces.
Polls and Surveys
While both polls and surveys are based on representative samples of a population polls are an estimate of public opinion based on one question or topic that is being presented while surveys look at variety of questions.
When evaluating polls remember the following:
- Name and background of polling organization
- Who paid for the poll
- How and when the poll was conducted
- The exact wording of the question asked
- The size of the sample and response rate
- The sample method
- The margin of error
- The relationship recent events may have had on the poll results
Remember these tips will help any reporter who chooses to use polls when reporting on a story. These tips can also help a reporter using samples but they should remember that a sample looks to represent a population while a poll aims for approximately 400 participants.
Business
The world of business often produces major news and is chalked full of math. Examples of business news include financial statements, profit and loss statements, balance sheets and ratio analysis. These documents provide a number of tools journalists can use when reporting on a businesses financial status or big financial endeavors.
Tips for dealing with financial statements:
- Numbers are often written in “thousands” or millions,” deleting the last zeros. Watch out for this because it can trick you.
- Figures in parentheses are negative.
- Compare net figures over time, it is more newsworthy to report changes over time than to report one years numbers.
These tips will help you analyze financial statements that are trying to trick a ill informed reporter.
Stocks and Bonds
Stocks and bonds are how most businesses make money. Bonds are also used by the government to raise funds. Understanding these money making tools is important for all journalists.
Stocks are sold by companies to share holders. Once a share holder is in possession of stock they become a part owner in the company but because there are so many stocks sold each year shareholders often represent a tiny portion of ownership.
Stocks change worth overtime. The more people want a stock the higher its price will go and the higher the shareholders worth will be. Mutual funds are also an option for stock enthusiasts but mutual funds invest in a variety of companies with a “mutual” interest as opposed to one specific company.
A bond is simply a loan form an investor to the government or other selling organization that earns interest over a period of time. Bonds are generally low-risk investments.
The bond owner pays “face value” for a bond and receives an annual interest rate. At the completion of the bond the owner will also receive the face value.
FOR EXAMPLE:
A bond is purchased for $1,000 with a 5 percent interest rate and a maturity date of 30 years. The bond owner will receive $50 each year and after 30 years will receive the $1,000 face value.
Bonds can be tricky because their value fluctuates with supply and demand.
Property Taxes
Property taxes are the largest source of income for local government, school districts and other municipal organizations. A property tax rate is determined by taking the total amount of money the government needs and dividing that by the total number of property owners. How much each owner pays is based on the value of their property. While most districts only take into account real property like real estate, homes and buildings, some also tax valuable assets.
Elon students and faculty see the importance of World Press Freedom Day
By Patrick McCabe
Written April 30, 2009
World Press Freedom Day takes place tomorrow all across the world as a way to draw national attention to the role of independent news and information and how it is under attack.
News organizations all across the world help make this day possible and many communications students and faculty at Elon University see this as an important day for all journalists.
Journalism student Noelle Clemente understands the importance of this day and what role it plays for all journalists.
“This day is so important for recognizing professional journalists,” said Clemente. “It’s extremely important to remember how important it is to allow journalists to the freedom and opportunity to openly explain the news as it is.”
Clemente acts as a citizen journalist, reporting on local issues and using a wordpress site to talk about the news that surrounds her local community.
“I think that citizens do have the same rights but it depends on the forum,” said Clemente. “I have a problem when people confuse citizens opinions for fact but I think they deserve the same rights.”
Journalistic freedom has become an international issue and World Press Freedom Day is helping to raise awareness about journalistic oppression internationally.
According to worldpressfreedom.org 673 journalists were arrested, 125 journalists were imprisoned and 70 journalists were killed in 2008.
Of the journalists killed four were in Africa, 11 in the Americas, 31 in Asia, nine in Europe and Central Asia and 15 in the Middle East and North Africa.
It appears that international freedom has put a heavy burden on journalists and journalistic rights are not being seen internationally.
Communications professor Tom Nelson sees an importance in international journalistic freedom.
“I think it’s important to realize that freedom of the press is not a western value it’s a universal value,” said Nelson. “I think it’s important for us to stand up straight ad say that to the entire world.”
This year the annual World Press Freedom Day campaign is sponsored by Agence France-Presse, Reuters, Associated Press, Russian Guild of Press Publishers, Reporters Without Borders, the Committee to Protect Journalists, Michel Cambon, Sanjeev Saikia and Tom Callaghan.

CELEBRATE! 2009 takes place at Elon University this week
By Patrick McCabe
Written April 27, 2009
All this week Elon University students, faculty and staff will take part in CELEBRATE! a weeklong celebration for students in academics and the arts. The week will include Programs seminars, art exhibitions, plays, a film festival, dance and music performance all presented by students and faculty.
Tuesday all classes will be cancelled to allow students to partake in the annual Student undergraduate Research Forum, also know as SURF day.
Students will present on a variety of topics and many of them have been researching these topics for months.
Senior Ben Smith will present on “The Difference in the Experiences of Male and Female Beginning Elementary School Teachers.” As an early education major Smith has had a lot of interest in this topic.
“I have put a lot of time into my research,” said Smith. “Many of my friends have been wondering where I have been all semester so I am hoping all my hard work pays off.”
Smith also presented his research this month at the National Conference on Undergraduate Research at the University of Wisconsin-La Crosse. His findings are based on interviews with female and male beginning elementary school teachers, and from scouring existing research, which uncovered several major themes.
Students will present all day on Tuesday and topics range from “Dioxin and Dopamine Alter Swimming Behavior in Larval Zebra Fish” to “The Glamorization of Cyberbullying in Gossip Girl.” Faculty presentations will take place between nine and ten a.m. and student presentation will begin just after that, taking place all across campus.

As Swine Flu outbreak intensifies Elon University plans what to do if an outbreak occurred on campus
By Patrick McCabe
Written April 27, 2009
A new strand of Swine Flu has broken out across the world reaching the United States, Mexico, New Zealand, Europe, Canada and parts of Asia. The Swine Flu is a respiratory disease of pigs caused by type A influenza virus that regularly causes outbreaks of influenza in pigs. The virus
causes high levels of illness and low death rates traditionally only found in pigs.
Many college campuses across the nation have implemented plans on how to deal with a health outbreak, like Swine Flu. At Elon University Jana Lynn Patterson, Assistant Vice President of Student Life, keeps students and faculty aware of health updates.
“The University also has a thorough flu pandemic preparedness and response plan that has been developed in accordance with state and national guidelines,” Patterson told students in an email. “While we do not anticipate having to initiate the plan, we do want [students] to know that we are prepared for escalated risks of exposure to the campus community and will respond if conditions warrant.”
While there is no immediate threat to the Elon community the University is prepared to tackle any health threats that may occur.
A case of the virus was discovered on the coast of North Carolina and students have begun to worry.
“I don’t have the best immune system,” freshman Rachel Long said. “If the virus comes to Elon I am pretty sure I will get it.”
Other students are worried that the school may have to close early if an outbreak occurs.
“I don’t know what I would do if that happened.” junior Noelle Clemente said. “I still have a lot of assignments for my classes and don’t know how my grades would turn out.”
As of now the university has not detected an outbreak on campus or in the surrounding areas but university officials assure students and faculty that all protective measures are being taken.
There have been 20 cases of the virus confirmed in the United States and St. Francis Preparatory school in Queens, New York seems to have seen the largest outbreak with eight confirmed cases. The school has been shut down temporarily and New York Mayor Michael Bloomberg has asked anyone showing symptoms of the virus to stay home and call their physician.
The biggest outbreak of the disease has been seen in Mexico City where the death toll has exceeded 100 individuals. Many cases in New Mexico did not seek medical attention soon enough and those that are now seeking medical treatment have been quarantined. In Mexico City they have closed down the majority of restaurants, bars, shopping centers and other public facilities.
“Given the reports out of mexico I foresee more outbreaks here in America,” Richard Besser, Director of the Centers for Disease Control told the press.
Sweet Signatures hosts ‘A Pink Tie Affair at Elon University
By Patrick McCabe
Written April 26, 2009
Elon’s only all female a cappella group had it’s last concert of the year on Saturday. The group is made up of 14 women and is very well known in the world of college a cappella. Their last album, Coming Into Focus, was runner-up for the Contemporary A cappella Society award for Best Female Collegiate Album and in 2007 the group placed third in the International Championship of Collegiate A cappella quarterfinal competition and was awarded Best Choreography.
Drawing in a crowd of over a hundred people the concert was a huge success. Seniors Lauren France and Lizzie Napier performed a special version of the song “For Good” from the musical Wicked.
“They sounded amazing,” said Elon senior Jenn Keldie. “I was blown away at how good the concert was, especially their duet.”
Keldie came with 15 friends who were all really excited to see their friends performing.
As the only two seniors France and Napier were pretty emotional after the concert.
“It is really bitter sweet,” France said. “I mean it feels great to see how all our hard work paid off but it is sad when I realized that this is my last concert with Sigs.”
Napier shared similar sentiments and was surrounded by friends and family following the concert.
“I just can’t believe it’s over,” Napier said. “I am really going to miss it all.”
While this was the last concert of the year for Sigs Elon’s all male a cappella group, Rip Chord, will perform Thursday night and the coed group, Twisted Measure, will have their spring concert on May 8 and 9.

High winds postpone Earth Day awareness project at Elon University
By Patrick McCabe
Written April 22, 2009
At 11 a.m. today members of the Elon University Sierra Club and other organizations planned on spreading trash, collected from the University, in front of the student center. The members of the club planned to dress in hazmat suits and sort out things that could have been recycled.
The high winds that swept campus today postpone the “landfill on the lawn.”
“We’re hoping the wind will die down and we will be able to sort through the trash later today,” sophomore Griffin Sager-Gellerman said. “We want to make students aware of how much they should be recycling.”
The “landfill on the lawn” was a part of Elon’s Earth Week. Earth Day events include “Moving Towards Carbon Free Living: Practical Steps to Reduce Carbon Emissions and Increase Energy Dependence” where authors of The Carbon Free Home, Stephen and Rebekah Hren will speak on “carbon free living.” The final event of the day will be cooking smores using alternative resources, reducing our carbon footprint.
Events for Earth Week will continue tomorrow and Friday, anyone interested in learning more about Earth Week should click here or stop by the Sierra Club’s table in the Moseley Center.
