Driving hazards: the phone factor: many things can distract drivers, but mobile phones are today's focus.
The fact is there are hundreds of things that can distract us from driving, making driver inattention a significant traffic safety concern. Each year, more than 42,000 people are killed and more than 3 million are injured in more than 6 million motor vehicle crashes on our nation's roads. The National Highway Traffic Safety Administration (NHTSA) estimates that 20 percent to 30 percent of all motor vehicle crashes--or 1.2 million accidents--are caused by a distracted driver.
Although studies conflict over which distractions cause the most accidents, one has drawn the most attention from lawmakers across the United States: the use of a wireless phone while driving.
Over the last three years, legislators have proposed bills on mobile phone use while driving in all 50 states. During the 2003 session alone, legislatures in 42 states considered such measures. Seventeen states have passed laws dealing with mobile phone use, at least 17 track mobile phone involvement in crashes, and legislatures in six states have approved studies to gather more information on the issue.
The rise in interest coincides with the dramatic increase in both the quantity and quality of wireless communications technology available in the car. The number of wireless phone subscribers in the United States has more than doubled since 1998.
The Cellular Telecommunications and Internet Association reports that more than 147 million people now subscribe to wireless services. A vast majority of these subscribers--more than 140 million--use portable devices that can be taken in and out of vehicles. NHTSA estimates that 73 percent of subscribers use their phones while driving.
The growth of wireless technology in the car has been matched by greater complexity and potential for distraction. Modern phones allow people to send digital pictures, surf the Web, receive updates on sports scores and check stock prices. The phones are not the only wireless technology, however, available to drivers.
Auto manufacturers are placing a variety of information and entertainment devices in new vehicles. In many cars, drivers and passengers now can check e-mail, follow navigation systems, receive fax messages and use a variety of gadgets that used to be available only with a fixed phone line.
Experts estimate that such in-vehicle technologies are likely to grow to a $30 billion to $50 billion industry by 2010.
Although it is clear that both the volume and sophistication of the wireless communications technology have grown dramatically over the last decade, there is little consensus whether this poses a significant enough threat to traffic safety to justify legislation.
Proponents of restrictions have argued that the unique distraction caused by the use of phones and other in-vehicle communication devices takes a driver's attention away from the road more dangerously than other activities.
Communications technologies in the car require the driver to cognitively interact with the device for longer periods of time than other activities, thereby diminishing the ability to focus on the task of driving, according to those who support restrictions.
"Other activities are not sustained to the level of cell phones in the car," says Massachusetts Representative Peter Koutoujian, sponsor of cell phone legislation.
"All the studies I need are on the road," he says. "Other distractions, such as eating or drinking take only a few moments, and the cognitive function on the phone is much different from speaking with a passenger."
Restriction opponents have cited the value of wireless phones and other devices as a reason against singling them out for regulation.
"Phones are an incredibly valuable safety device," says Kimberly Kuo, spokesperson for the Cellular Telecommunications and Internet Association. "Every day, more than 160,000 emergency calls are placed on wireless phones. And they can be used to promote on-the-road safety programs, such as the Amber Alert system."
Opponents also argue that there is little evidence that wireless phones and other devices are any more distracting than other normal activities in the car, such as eating, grooming or using the radio.
"Based on research, studies rank cell phones between fifth and eighth on a list of distractions," argues Kuo. "Wireless is the new kid on the block, and people are trying to get comfortable with that. We need to remind people to drive safely, but legislation is not a quick cure-all."
In fact, there are few hard crash statistics on the topic. Until recently, only a handful of states collected information regarding the involvement of mobile phones in motor vehicle crashes.
Although California, Florida, Minnesota, Oklahoma, Pennsylvania and Tennessee have published data on the number of crashes that cited phones or CB radios as factors, the results are inconclusive. The existing state statistics indicate that cell phones are a factor in less than 1 percent of motor vehicle crashes in all six states.
Critics, however, have argued that the data are flawed because mobile phone use is difficult to detect at crash scenes. Unlike drunk driving or seat belts, investigators are forced to depend on witnesses and self-reporting by drivers to determine whether a cell phone was in use at the time of the crash, making the information less reliable.
A controversial report to the California Legislature highlights some of the problems with data collection. Last year, the commissioner of the California Highway Patrol (CHP) withdrew an initial draft of a report after a closer look at crash data indicated that some law enforcement agencies may have underreported the number of traffic crashes in their jurisdictions that involved cell phone use.
The original report found that during the final nine months of 2001, investigating officers determined that 913 accidents were directly linked to the driver's use of a mobile phone. Of those, 423 crashes resulted in injuries, and three involved a fatality.
Before the final report was released, however, a study of the same crash data by the Los Angeles Times found that during the same period, driver use of a mobile phone was linked to nearly 4,700 crashes.
A subsequent report by the California Highway Patrol indicated that from Jan. 1 through June 30, 2002, inattentive driving was cited as a factor for 5,677 people out of the 491,083 involved in crashes throughout the state. Cell phones were cited as a factor in 11 percent of inattention-related crashes, more than any other single factor.
Several academic studies have shown mixed results when attempting to determine the risk posed by a driver using a cell phone. A recent article published by the Harvard Center for Risk Analysis estimated that cell phone use by drivers may cause approximately 2,600 deaths, 330,000 moderate to critical injuries, and 1.5 million instances of property damage in America per year.
The report conceded, however, that because information on cell phone use by motorists is limited, the uncertainty of the estimated effects of use is wide. In fact, the report concluded that fatality estimates range from 800 to 8,000 per year, and injury estimates range from 100,000 to 1 million per year.
A 2001 report by the University of North Carolina Highway Safety Research Center ranked cell phone use eighth on a list of distracting activities that were cited in crash reports. Researchers estimated that cell phone use caused 1.5 percent of distraction related crashes, placing it behind such activities as adjusting the radio, adjusting climate controls and eating or drinking. However, researchers acknowledged that missing data and small sample sizes could limit the conclusions drawn from the report. Dozens of other studies have further muddied the debate with conclusions backing both sides of the issue.
The lack of hard evidence has increased data collection efforts in the states. The national Governors Highway Safety Association released a revised edition of the Model Minimum Uniform Crash Criteria in June, which included changes intended to help gauge the effects of driver distractions.
The criteria, which were developed in collaboration with NHTSA, the Federal Highway Safety Administration, the Federal Motor Carrier Safety Administration, and numerous state and local agencies, describe what kinds of information states need to collect. The model criteria are intended to help policymakers paint a more accurate picture of the role of cell phones and other distractions in motor vehicle crashes.
"There is not enough conclusive data on the topic," says Jonathan Adkins, communications director for the Governors Highway Safety Administration. "The research is contradictory, and we want the best data that we can get. If it's included on crash forms it may help. There is a lot of room for error because it's difficult to prove, but any data we get is better than what we have now," he says.
State legislatures are also taking an active role in improving information collection.
Seventeen states now require law enforcement officers to collect information on the use of a cell phone in a crash, up from just two states five years ago. Additionally, legislatures in Delaware, Louisiana, New Jersey, New York, Pennsylvania and Virginia passed measures to study the effects of wireless phones on traffic safety. Pennsylvania's Joint State Government Commission published a report on driver distractions and public safety in December 2001.
A special legislative task force in Delaware published a report on driver distractions this year.
A common misperception is that a lot of states are considering legislation to ban the use of all phones and wireless devices in the car. In fact, state lawmakers are contemplating a broad range of proposals. The most common approach--considered by legislators in 32 states this year--is to prohibit driver use of hand-held phones while allowing the use of hands-free devices. So far, only New York has passed the handheld phone restriction into law.
However, over the last year, legislators in California's Assembly, Connecticut's House and New Jersey's State Senate voted for similar measures, although none have won the approval of the full legislature.
Opinions differ whether hands-free requirements will improve traffic safety. Many academic studies--including one published in the New England Journal of Medicine in 1997 and another published in Sweden this year--suggest that the cognitive distraction caused by cell phone use is a problem that cannot be eliminated by hands-free requirements. Most have concluded that there is no distinction in accident rates between drivers using hands-free and hand-held devices. However, proponents of hands-free bills see it differently.
"It's a bill that will save lives. It's just that simple," says Assemblyman Joe Simitian, sponsor of California's AB 45. "There is no study that says one hand is more safe than both hands. Even if hands-free is still a distraction, and this bill proposes a partial solution, a partial solution is better than no solution.
"We have a readily available technology that can save lives, why not use it," he says.
Connecticut Representative Richard Roy sees hands-free requirements as a way to begin tackling driver distraction concerns.
"I would like to address some distractions that we can mitigate," he says. "If we can get something on the books, we can gain a foothold on this issue."
Legislators have also broadened the cell phone debate to encompass particular drivers who might pose a greater risk on the road. Maine and New Jersey now prohibit drivers under the age of 21, who have only a learner's or instructional permit, from using any mobile phone while driving. It's an approach that was considered by eight other states this year and endorsed in a June 2003 report by the National Transportation Safety Board (NTSB).
"Learning how to drive and getting comfortable in traffic requires all the concentration a novice driver can muster," says NTSB Chairman Ellen Engleman. "Adding a distracting element like a cell phone is placing too many demands on a young driver's skills."
Arkansas, Arizona, Illinois, Massachusetts, Rhode Island and Tennessee prohibit school bus drivers from using cell phones. Four other states considered similar measures this year.
Ten states considered legislation in 2003 intended to address a wide range of activities in the vehicle, not just cell phone use.
"The cell phone is one of many distractions," says Senator Biagio "Billy" Ciotto, who sponsored such legislation in Connecticut this year. "I'm not opposed to prohibiting cell phone use," he says. "But I'm looking for statistics. Cell phones are ranked as sixth or seventh among factors that cause accidents. If we're fair to everyone, we shouldn't single out the cell phone."
So far, much of the public policy debate regarding cell phone use while driving has occurred outside of Washington, D.C.
Although a bill was proposed in the U.S. Senate this year to require states to prohibit the use of hand-held phones while driving, it is not expected to garner much support. Similar legislation in 2001 failed to make it out of committee.
In counties, cities and towns across the United States, the story is much different. Nearly two dozen local communities--in Florida, Massachusetts, New Jersey, New Mexico, New York, Ohio, Pennsylvania and Utah--have passed ordinances that restrict the use of cell phones while driving. USA Today has estimated that as many as 300 local jurisdictions have considered regulations.
Some state legislatures, concerned that local regulation might lead to a confusing piecemeal approach, have reacted to local ordinances by explicitly pre-empting them. Florida, Kentucky, Louisiana, Mississippi, Nevada, New York, Oklahoma and Oregon all specifically prohibit local jurisdictions from restricting cell phone use while driving.
As the number of people who own wireless phones continues to grow, consideration of legislation to restrict the use of them in the car seems likely to follow. Polls indicate that many drivers support initiatives to curb cell phone use in the car, even if they don't believe that the phone impairs their driving ability.
A March 2003 survey by the Gallup Organization found that 48 percent of drivers perceive that making outgoing calls can make driving dangerous. Forty-four percent of drivers perceive that receiving calls can be dangerous. Twice as many people--88 percent of drivers surveyed--indicated they support increased public awareness of the risk of wireless phone use while driving. Seventy-one percent of drivers support prohibitions on hand-held phones while driving, according to the Gallup report. And 67 percent support insurance penalties for being involved in a crash while using a cell phone; 61 percent support double or triple fines for traffic violations involving cell phone use; and 57 percent support a ban on all wireless phone use while a car is moving, except for emergency situations.
A working group formed by the National Conference of State Legislatures released a report on driver distraction in Match 2002, that included 14 principles for state legislatures. The Driver Focus and Technology Partnership--composed of state legislators, legislative staff, wireless service providers, auto manufacturers, interested companies, safety groups, academics and others--could not reach agreement on controversial issues, such as hands-free restrictions.
Participants, however, did agree on less contentious subjects, including the important role of states in policy decisions, the need for driver education, prohibitions on the use of phones by school bus drivers, and the need for better information. Although the group did not draft model driver distraction legislation, the findings may help guide future legislative activity.
While many activities can potentially divert driver attention, the cell phone is a highly noticeable distraction in the car, which makes it a target for restriction. It's easy to spot the profile of a driver with one hand to the ear and know that he or she might not be totally focused on the road. It may not be so easy to spot a driver who is tuning a radio or just thinking about something at work.
"Driver distraction has always been a problem," says Connecticut's Senator Ciotto. "But it's the cell phone that has drawn all the attention to the issue." How legislatures decide to package or separate cell phones from other distractions will help determine the future scope of legislative activity.

SAN DIEGO, April 10, 2013 /PRNewswire/ -- Zodiac Pool Systems, Inc. announces premium consumer-focused enhancements to its popular Polaris ® 9400 Sport robotic pool cleaner and Zodiac T5 Duo® suction cleaner, and unveils its new Zodiac T3™ suction pool cleaner. Zodiac engineers conducted consumer and dealer research for years prior to incorporating the improvements, thereby ensuring the latest innovations contributed to a better experience for pool owners.
(Logo: http://photos.prnewswire.com/prnh/20130212/LA58482LOGO)
Zodiac's boldest and most sought-after enhancements are for its sleek robotic cleaner, the Polaris 9400 Sport. Known for visionary designs that maximize cleaning power and energy efficiency, Zodiac's robotics team has developed three superior accessories that complement the cleaner and dramatically surpass other options available on the market. They include:
- The new Polaris lift system revolutionizes the consumer experience by preventing the difficult and awkward task of pulling the cleaner out of the pool. With the press of a button, the cleaner will climb a wall of the user's choice and wait at the water's edge to be removed. As the consumer begins to pull the cleaner out, the 9400 will automatically evacuate its water, reducing its weight from nearly 40 pounds to just 16 pounds in a matter of seconds.
- The 7-day programmable timer eliminates the need for daily input from the pool owner. Where consumers formerly had to physically start their cleaner every day, the timer allows them to pre-set automated cleaning cycles for hassle-free cleaning convenience.
- The newly designed premium caddy provides the much needed transport and storage capabilities for the cleaner when it is not in use. The new caddy requires no tools to assemble, and with its premium alloy construction and a compact design, the caddy is easy to use and saves space.
The 9400 Sport is ideal for all pool types, and is especially appropriate for pools with modern features such as beach entries. It utilizes several patented Zodiac technologies including ActivMotion Sensor™ intelligence and Vortex Vacuum technology. The 9400 Sport costs just pennies a day to operate, reducing energy consumption up to 90 percent. It retails for $1499 MSRP and qualifies for an in-season rebate of up to $150.Zodiac's new 2013 suction cleaner, the T3, is a a smart, simple, and swift addition to the T series family. It includes many of the same innovations as Zodiac's leading suction cleaner, the T5 Duo, but on a smaller frame. The T3 incorporates the following key features:
- Zodiac pioneered the design of diaphragm cleaners more than 20 years ago, and has improved the diaphragm in its T series cleaners to be significantly more durable and quieter. The silent "Dura Life" diaphragm provides maximum durability and silent operation.
- A single, 14 inch disc with Zodiac's patented finned design for aggressive wall climbing and unimpaired maneuverability over lights, drains and wall fittings.
- A fixed wheel deflector to help steer the cleaner and prevent hose entanglement.
- Tool-free serviceability due to a quick-release hand nut that makes the cleaner exceptionally easy to use and service.
- A duo disc system with two overlapping discs for maximum flexibility, cleaning coverage and pool adhesion. The front disc is for steering, while the back disc, with Zodiac's patented fin design, is for aggressive wall climbing. The discs provide a 17-inch cleaning footprint – the largest in its class.
- An adjustable wheel deflector that can be positioned at any point along the cleaner hose to prevent entanglement of the hose and cleaner.
- The T5 also boasts the same silent Dura Life diaphragm and tool-free serviceability as the T3.

Man who died in a Martin County house fire not yet identified
JENSEN BEACH — Authorities have not released the identity of the man who died Monday at a house fire in the 1700 block of Seneca Avenue.
About 9 a.m. Monday, Martin County Fire Rescue responded to fire in the house north of Baker Road and east of Northeast Dixie Highway and found the home half-engulfed in flames.
"It was gone so quickly, it happened in just a couple of minutes," said neighbor Debbie House, who had called 911.
Inside the home, crews found a man's body lying next to a door leading to the carport. Investigators would not say whether the man may have been trying to escape or what caused the blaze.
On Tuesday, Capt. Ross Holt of the State Fire Marshal's Office and K-9 Ember were searching the charred debris for accelerants. Ember, a golden labrador, alerted Holt to a trace of accelerant found near the carport area.
Investigators would not comment on what was found.
Dennis Scanlan can only hope that the body found inside this home is not that of his best friend.
"I usually stop by every morning to take him with me for a cup of coffee and stuff," Scanlan said Monday.
Neighbors said the man was about 48 years-old and had a daughter. Even though he had some personal struggles in recent years, neighbors said, he would go out of his way to help a friend.
"No matter how he was feeling, he'd help somebody else. He made sure he took care of himself, though, you know," Scanlan said.
Neighbors said the man was hard of hearing and when the fire had broken out, at least one person was seen banging on the door trying to get his attention before firefighters arrived.
Whether the man's hearing impairment worked against him is also a question that can't be answered yet. The fire officials said people with disabilities can call them so that if there's ever an emergency at their home, emergency responders have that information in advance.

From Space to Place
Defined by human activities, places are ever-changing, ever-decaying, and always being reborn, often through collective action and collaboration. From Space to Place is an exhibition that explores placemaking—the transformation of a space into that which has a distinct identity. Curated by Artemis Ettsen, a graduate student in the School of Architecture, and Teréz Iacovino, a graduate student in the Department of Art, the exhibition is a platform for reexamining place and one's relationship to it.

Desire Lines Tour with Common Room
June 5, 6:00 - 8:30pm
Leaves from Regis Center for Art
Andy Sturdevant and Sergio Vucci will lead a Common Room tour around Minneapolis, looking at desire lines around the city from the back of a vintage chartered bus. "Desire lines" are the informal paths created by foot traffic across public spaces not initially intended for foot traffic. Any time you see a dirt path across a patch of grass or up a hill between two sidewalks, or footprints in the snow leading from one place to another, that's a desire line. Looking at traditional desire lines, as well as expanding the idea beyond footpaths, we'll see how people create their own spaces, make shortcuts, defy authority, and carve out new path systems.

Leaves from Regis Center for Art
The goal of the Reverse Scavenger Hunt is to reverse-collect things from the world around you. Instead of acquiring or consuming objects and experiences and bringing them back to home base, you create, cause, disperse and share them with your environment. You will journey with a team via bicycle into the city and combine items and interactions with places/people from a given list, while infusing life into your surroundings! A bicycle and camera are recommended for this event.

Exhibition Description
Defined by human activities, places are ever-changing, ever-decaying, and always being reborn, often through collective action and collaboration. From Space to Place is a group exhibition, curated by an architect and artist team that explores placemaking—the transformation of a space into that which has a distinct identity. Placemaking brings together creative and cultural resources, most importantly people, whose combined efforts have the potential to reimagine and reconstruct space into authentic, dynamic, and resilient communities. While "space" typically refers to the physical or geographical environment, "place" ricochets between the emotional, the social, and the political.
The exhibition is a platform for reexamining place and one's relationship to it. From Space to Place features projects from local, national and international artists and designers working in a variety of media. The projects are a result of collaborative and individual efforts to interpret and investigate the phenomena of place and placemaking. The exhibition traverses the concepts of memory, intimacy, loss, potential, and regrowth.
An art gallery is inherently a placeless space, so there is a tension inherent in the act of displaying work about place within the gallery. Rather than attempting to replicate placemaking within the gallery, the exhibition becomes a collection of past events and future possibilities. This collection further serves as a complement to the numerous and exciting placemaking initiatives occurring within the Twin Cities and beyond.
Katherine E. Nash Gallery Mission
The Katherine E. Nash Gallery is a research laboratory for the practice and interpretation of the visual arts. We believe the visual arts have the capacity to interpret, critique and expand on all of human experience. Our engagement with the visual arts helps us to discover who we are and understand our relationships to each other and society. The Katherine E. Nash Gallery will be a center of discourse on the practice of visual art and its relationship to culture and community -- a place where we examine our assumptions about the past and suggest possibilities for the future. The Nash Gallery will play an indispensable role in the educational development of students, faculty, staff and the community. Visit us at http://nash.umn.edu/.
Department of Art Mission
The Department of Art provides an introduction to the practice of art for all students as well as immersive training for emerging artists. We promote creative expression and conceptual development through a broad range of art disciplines and practices. Initial experiences emphasizing traditional methods are supplemented at intermediate and advanced levels by experimental processes. We offer courses in painting and drawing, photography, printmaking, sculpture, ceramics and experimental media (EMA). Students pursue their work in our state of the art facilities, mentored by our faculty, all artists recognized in their fields. Visit us at http://www.art.umn.edu/.
Parking is available in the 21st Avenue Ramp. Hourly or event rates will apply.

Like or Dislike: 3 1
I'm just going to keep it simple. Obama is continuing the Bush agenda. Ron Paul is the only hope I feel there is for America...and the world.
Highly rated. What do you think? 11 0
I'd like Ron Paul to end his affiliation with the Republican party. As a liberal libertarian, I see both the Democratic and Republican parties as evil twins, side-by-side on the fascism scale. I'd be ashamed to call myself a member of either party. Ron Paul will have my support if he runs as a third party candidate. As the Republican nominee he'll have too much political baggage to make his platform believable.
Like or Dislike: 3 5
What you don't understand is, by running under one of the two major parties, he gains access to various things that otherwise would be much harder for him to get.

True, but what I am saying is, that the way the current system works, going independent would actually hinder him in some ways, whereas picking either democrat or republican, helps in the overall race.
In a video I saw, someone asked him if he would run independent, and gave his reasons why he wouldn't. I don't remember exactly what they were, but what I said above, is pretty much the gist of it. He stands to gain more by picking one of the two parties.

CNN and FOX do not like Ron Paul because he contradicts everything they talk about. CNN and FOX love to have the right and the left fighting on the same issues every four years. but this is not about right or left, this is about right and wrong, it's about freedom, stop letting the right and the left divide this country. a country divided against itself shall not stand, this is a revolution Americans, either you're going to stand up and fight for your rights as our fathers have or you will have your rights stripped from you in the blink of an eye. Vote Ron Paul 2012

I know that ignorance is bliss among any one dealing or interested in politics but this really sets the bar. Ron Paul can and would beat Obama in a landslide victory if Ron Paul makes the Republican nomination. You must be living under a rock if you do not see that yes, Obama may have suckered American into his lunacy by offering a word that sounds so great like "change", but the American people in whole are not that stupid. They have woken up and started to pay attention. Not just to party affiliation, but to the messages these people are putting out there. They no longer take politicians at their word but do their own research and are starting to find the "TRUTH". They are understanding how important the Constitution of the United States is and are understanding that Ron Paul is the only man running that believes wholeheartedly in it.
As far as Fox News. It was my news source of choice and still is, however, I have realized that they are bias and unbalanced as are the rest of the media. They report "more" of the truth but still not the whole truth on alot of issues. You must do your own research and find the truth on your own. Fox is scared that the truth will get out and they as well as the government will start to lose control of the mass populous.

It is because of this attitude you and many others hold that people like Ron Paul do not get elected. If you just go along with everyone else and follow you will end up with the same old shit. Why don't you actually consider the best candidate? You know, If people like you would actually have the courage to stand up and oppose the status quo we would not be in this disaster.

Seriously, who is going to vote for a mumbling nearly 80 year old libertarian wingnut who looks like a gremlin and is easy to trip up in an interview. You fukkers are hilarious!....
And you are shallow! What kind of lunatic votes based on looks and smooth talk? We are looking for someone qualified to run our country according to the Constitution not Dictatorship. Talk of hope and change (which of course has been so far nothing more than hot air along with QE...infinity to ensure economic collapse) falls on deaf ears to those who have the compacity to think for themselves rather than allow media and society to tell them how they should think. Personally I've seen what the so-called suave candidates can do - and I'm not interested. This is an election - not an audition for the next Miss America Contest! I don't care what the President looks like; I am interested in his job performance and adherance to uphold the CONSTITUTION. So far the only candidate I see that fights for our Constitutional Rights as well as has sound strategies to fix this economical mess is Ron Paul. If you have something significant to add regarding potential candidates by all means share. Otherwise, please consider taking your shallow comments and vulgarity elsewhere - it is an embarrassment and insult to the integrity of all that is good and just - what America use to be. There is ignorance and then there is stupidity; if you are confused on the difference perhaps there is some hope for you - look it up and then learn to research and analyze - it is called critical thinking and as a human being you have the capacity to develop it!

Definition of Freedom: "being able to do whatever you want"
There are endless laws & rules, even telling you how you should behave towards others. Stop listening to other people & decide by yourself.
Lots of people disagree with prositution,
You must realise most of the women are drug addicts, alcoholics most of
them have really bad lives of abuse ect.
1st if prostitution was legal it would clear the street corners giving the women a
safe environment to work. 2nd most women would be able to get clean
& start a new life which is a far better solution.
Drugs also should be legal, you can buy a pack of smokes & it's clearly labled with the risks of smoking, it is your choice in the end.

When liberals participate in the polls, Dr. Paul does much better and beats all of the republicans because he appeals to a lot of liberals as well. I was a registered independent and typically voted more liberal, but last week I re-registered as a republican to vote for Dr. Paul in the primaries. I hope that more liberal-leaning people who really like Dr. Paul will register as republicans to vote for him in the primaries.

Truth is sweet to the ears. The Spirit will testify to millions of Americans this year as the principles of liberty are finally heard.
Conservatives know that the free market is imperative to freedom and the only cure for poverty but they have misplaced their trust in the military industrial complex. Conservatives tend to love the Lord but they have been misled to believe that they should use force to forbid people to break His laws by misusing drugs & participating in prostitution.
Liberals have caring hearts & want to help the poor & elderly but have been mislead to believe that its ok to steal from one group of people to "help" another group. They need to learn that stealing is still stealing & if you tax the engine the caboos will only get further behind.
The simple principle is that government can only have powers given to it by the governed. Therefore we can only legislate things that we could morally enforce individually with our own gun. Otherwise the creature exceeds the creator & becomes master.

INTERPRETERS vs COMPILERS
We start by defining what interpreters and compilers are and give examples of both. Then two simple problems are done in OCTAVE (interpreter) and two compiler languages (c and fortran) to illustrate how these tools are used. A more realistic problem (Matrix Inversion) for different matrix sizes is done in OCTAVE and compared to LAPACK. Based on this problem conclusions are drawn about the use of interpreters and compilers.
In this online-tutorial we start by describing briefly how compilers and interpreters work. The most important issue is: which should you use, and that depends on what kind of code you are developing.
Fortran, c/C++, Pascal and ALGOL are compilers.
A compiler analyses all the statements in a program and links the code (using libraries) to produce an executable. To run the program you submit the executable which would produce some output. To make changes in the program you must repeat these steps.
OCTAVE, MATLAB, MAPLE, R and APL are interpreters.
An interpreter translates one high-level language command into low-level machine instructions and executes that command at once. The interpreter takes one command at a time, however the user can place several commands into a script file and execute the commands in that file one at a time.
Simple Comparison
First let's illustrate how OCTAVE (an interpreter) works. The second example is done in OCTAVE(interpreter) and both c and fortran (compilers) to illustrate the two approaches. Finally, the third example (in the next segment), a more realistic one, illustrates and answers: which should you use (a compiler or an interpreter).
OCTAVE and MATLAB are very similar. They have a lot of similar functions but there are some that are different.
Here is an example in OCTAVE:
[nickc@nar316:~] octave GNU Octave, version 3.2.2 octave:1> x=3.0; octave:2> xsq=x*x xsq = 9 octave:3> quit [nickc@nar316:~]
The first line invokes the interpreter (OCTAVE) which responds on the next line with the name of the interpreter and version. Then the interpreter prints the prompt with the line number:
User types a command (assigning the value of 3.0 to variable x) followed by a semicolon (;) and then presses CR (Carriage Return). The effect of the semicolon at the end of the command instructs the interpreter not to print the answer (i.e. value of x in this case is not printed on the screen).
The next command computes variable xsq as the product of x by x. Since the command does not end with a semicolon the answer is printed on the next line.
To terminate the interaction session the user types the command: quit
Here is a second example using OCTAVE:
[nickc@nar316:~] octave GNU Octave, version 3.2.2 octave:1> sum=0; octave:2> N=1000 N = 1000 octave:3> for i=1:N > sum=sum+i; > endfor octave:4> sum sum = 500500 octave:5> my_sum=N*(N+1)/2 my_sum = 500500 octave:6> quit [nickc@nar316:~]
In above example, the user sets sum=0 and N=1000 in the first 2 commands. The third command is a for-loop starting with the clause:
for i=1:N
The interpreter will read instructions until an endfor clause is detected.
In the body of the for loop we are adding the index variable i and not printing the answer. On line 4 we print the answer (sum of integers from 1 to N).
Line 5 verifies the answer with the analytical formula: my_sum=N*(N+1)/2
When the algorithms become more complex rather than typing each command at the OCATVE prompt you can place all the commands into a script file. An OCTAVE script file has the *.m extension (e.g. my_commands.m). To execute the commands in the script file type the name of the file without the extension (e.g. my_commands) into the OCATVE prompt.
Let's place the commands of the second example into a file called ex2.m as shown next:
# OCTAVE script file ex2.m # Commands for example 2 sum=0; N=1000 for i=1:N sum=sum+i; endfor sum my_sum=N*(N+1)/2
To execute the commands in the OCTAVE script file ex2.m do as follows:
[nickc@nar316:] octave GNU Octave, version 3.2.2 octave:1> ex2 N = 1000 sum = 500500 my_sum = 500500 octave:2> quit
or you can run it in batch mode by submiting it as a job using:
#!/bin/bash # script file: sub_job if [ $# -ne 1 ]; then echo echo "Must have 1 argument specifying the OCTAVE file" echo echo "For example: ./sub_job ex2.m " echo exit fi OCTAVE_FILE=$1 sqsub -t -r 15m -o OUTPUT_${OCTAVE_FILE%%.*}_%J octave ${OCTAVE_FILE}
For completeness here is the file sumN.c which solves the problem in the second example using the c compiler, pathcc:
#include <stdio.h> /* This program prints the sum of integers from 1 to N */ #define N 10000 int main(int argc, char **argv) { int i, sum, sum_formula; sum = 0; for (i=1 ; i <= N; i++) sum = sum + i ; printf("For N = %d the sum = %d\n",N,sum); sum_formula = N*(N+1)/2; printf("and using formula sum = %d\n",sum_formula); return 0; }
and the equivalent fortran file sumN.f90:
! file sumN.f90 program sumN integer, parameter :: N = 10000 integer :: i, sum, sum_formula sum = 0 do i=1,N sum = sum + i enddo write(6,1001) N,sum 1001 format("For N = ",i8," the sum = ",i10) sum_formula = N*(N+1)/2 write(6,1002) sum_formula 1002 format("and using formula sum = ",i10) end
To compile and execute the c program you would do these commands:
[nickc@nar316:/work/nickc/INTERPRETERS_vs_COMPILERS] pathcc sumN.c [nickc@nar316:/work/nickc/INTERPRETERS_vs_COMPILERS] ./a.out For N = 10000 the sum = 50005000 and using formula sum = 50005000
and for the fortran program you would do:
[nickc@nar316:/work/nickc/INTERPRETERS_vs_COMPILERS] pathf90 sumN.f90 [nickc@nar316:/work/nickc/INTERPRETERS_vs_COMPILERS] ./a.out For N = 10000 the sum = 50005000 and using formula sum = 50005000
Matrix Inversion (Example 3)
The third example in this online tutorial defines a STRIDWAD matrix, stored in the array A, and a vector X described in:
Once the matrix A and vector X are defined, the matrix-vector product, A*X, is computed and stored in the vector RHS. Then, using A and RHS the linear system of equations is solved and the solution is saved in the vector XX which should be identical to X.
In preparation for our third example, let's introduce OCTAVE functions. You can define an OCTAVE function by typing it into a *.m file which starts with the word: "function". Here are the definitions for two functions:
# file: INIT_MY_MATRIX.m function A = INIT_MY_MATRIX (N) if (nargin != 1) usage ("A = INIT_MY_MATRIX (N)"); endif NH = N/2; NH1 = NH + 1; # Diagonal elements MD = 3*eye(N); # Upper diagonal ii=-1*ones(N-1,1); UD=diag(ii,1); # Lower diagonal LD=diag(ii,-1); # ANTI-DIAGONAL AD=fliplr(eye(N)); A = UD + MD + LD + AD ; return endfunction
# file: INIT_MY_VECTOR.m function X = INIT_MY_VECTOR(N) if (nargin != 1) usage ("A = INIT_MY_MATRIX (N)"); endif X = find(ones(N,1)); return endfunction
Note that the name of the file (e.g. INIT_MY_VECTOR.m) without the *.m extension is identical to the function name inside the file.
Once these functions are defined (by writing them into the *.m files), you can use them either interactevly or submiting a batch job from the same subdirectory where these functions appear.
Here is a script file for a short version of example 3:
# file: short_ex3.m # OCTAVE commands for example 3 t0 = clock (); N=10 A = INIT_MY_MATRIX(N) X = INIT_MY_VECTOR(N) RHS = A*X # Now use A and RHS to find new XX XX = A \ RHS elapsed_time = etime (clock (), t0) [total, user, system] = cputime (); total user system N
To run it interactively you type:
octave GNU Octave, version 3.2.2 octave:1> short_ex3 N = 10 A = 3 -1 0 0 0 0 0 0 0 1 -1 3 -1 0 0 0 0 0 1 0 0 -1 3 -1 0 0 0 1 0 0 0 0 -1 3 -1 0 1 0 0 0 0 0 0 -1 3 0 0 0 0 0 0 0 0 0 0 3 -1 0 0 0 0 0 0 1 0 -1 3 -1 0 0 0 0 1 0 0 0 -1 3 -1 0 0 1 0 0 0 0 0 -1 3 -1 1 0 0 0 0 0 0 0 -1 3 X = 1 2 3 4 5 6 7 8 9 10 RHS = 11 11 11 11 11 11 11 11 11 22 XX = 1.0000 2.0000 3.0000 4.0000 5.0000 6.0000 7.0000 8.0000 9.0000 10.0000 elapsed_time = 0.0048676 total = 0.24096 user = 0.15298 system = 0.087986 N = 10 -- less (100%) (f)orward, (b)ack, (q)uitPress Control-C again to abort. octave:2> quit
For a larger system of equations (N=12000) we use the script file long_ex3.m:
# file: long_ex3.m # Commands for example 3 t0 = clock (); N=12000 A = INIT_MY_MATRIX(N); X = INIT_MY_VECTOR(N); RHS = A*X; # Now use A and RHS to find new XX XX = A \ RHS elapsed_time = etime (clock (), t0) [total, user, system] = cputime (); total user system N
and submit the job in batch mode using the script sub_job (described earlier) with argument long_ex3.m as follows:
[nickc@nar316:] ./sub_job long_ex3.m submitted as jobid 1524992
The output file, OUTPUT_long_ex3_1524992, for the job was:

(1) Developing a model with an interpreter is much easier because interpreters have many more commands and the development is carried out interactively. This results in a much faster development cycle. (2) OCTAVE and other interpreters could run as fast as compiled code for smaller models. As seen from the table in the previous segment OCTAVE in all cases runs in about half the time of the LAPACK execution time. (3) Compiled code however could run much larger models. (4) Since mpi can be used with compiled codes this extends the size of the models to even a higher dimension. In this case LAPACK programs can be extended to ScaLAPACK.

Answer to which should you use:
For smaller models an intepreter would be more appropriate. However, if the model exceeds the memory then you have no choice but to switch to a compiler.
For the development of new algorithms it is easier to do all the preliminary testing using an interpreter. If the memory requirements are met then there is no need to switch to a compiler.
But for much larger models the compiler with mpi is more adecuate.
Using OCTAVE we were able to invert matrices up to N=16,000. For higher dimensions LAPACK was able to go up to N=30,000 and for even higher models ScaLAPACK went up to N=250,000 (using 256 processors).
