Searching for Evidence
To answer key questions and guide evidence-based practice, it is optimal to identify all available relevant better quality studies or valid and up-to-date syntheses of such studies. In recent years, much work has been devoted to developing effective search strategies to reach these ends. A good search strategy will identify a high proportion of available relevant studies without requiring us to sift through much irrelevant material. Below you will find selected key resources on this topic.

WASHINGTON, DC (WUSA*9 Call For Action)-- The budget is stretched thin, the holidays are just around the corner and you would really like a few days in the sunshine this winter. If you are like many of us, finding extra money is difficult, so you think, why not work from home. There are so many online ads, surely there is something that fits your needs.
Maybe, or maybe not! According to the website RateRacerebellion for every legitimate job offer there are 60 scams.
There are opportunities and then there are scams. How can you tell them apart?
Distinguishing between a legitimate work at home job and a fraud isn't easy. However, there are some red flags.
MORE: How To Avoid The 5 Newest Job Search Scams
MORE: Top Ten Work At Home And Home Based Business Scams
For example, an online ad that says no experience is needed and neither is a resume. If it were a real job, the company would want to know something about the person they were considering for employment. Crooks don't care about your qualifications because there is no legitimate job, just a fraud designed to rob you. Besides, asking for qualifications would limit the pool of potential victims.
Another sign of a fraud is the claim that you are going to make an incredible amount of money in just a few hours a week. Sure, and I want to sell you a bridge! One thing missing from this claim is a description of what you will be doing. The ad makes big promises but gives few details on how you will earn the money.
Another common warning sign is the requirement that you have to pay to get the job. While there are a few exceptions, generally you should not have to pay to get a job. Do not give out personal information until you have thoroughly researched the company.
How can you find a legitimate work at home job?
Familiarize yourself with the various scams and then proceed to websites that provide useful advice and information on jobs. There are sites that serve a specific population, for example the Work at Home Online Magazine (WAHM) not only provides a lot of information about jobs it even has recipes for working moms!
MORE: Federal Trade Commission Helpful Tips
No matter where you find a job lead, evaluate it carefully because scams can slip through the most careful screeners.
MORE: Internet Crime Complaint Center
MORE: Five Ways To Find A Scam In An Online Job Ad
In addition, if you find a reliable internet company that provides legitimate job leads, keep in mind that most of these websites have ads that are not screened by the site sponsors.
Do you hear from many consumers who have been victims of online job scams?
Unfortunately, it is one of the most common online frauds. A consumer contacted our WUSA*9 Call For Action line for help because she was hired by a company that sent her money orders with instructions to deposit them in her bank account, keep a percentage as her salary and wire the remainder to a variety of people. She became aware of the scam when the bank told her the money orders were counterfeit and she now owes her bank over $7,000. This scam has been around for a long time and continues to snare job seekers.

Metallica are heading to Antarctica for a very special winter concert.
The heavy rockers have teamed up with Coca-Cola bosses for the top secret show, which will reportedly take place between Dec. 2 and 15.
It appears the gig is what drummer Lars Ulrich was talking about when he recently told a San Francisco radio station that the band was planning "a very interesting thing" adding, "There's another frontier heading in Metallica's direction in December".
He refused to go further, revealing, "If anybody even knew that I just said what I just said, they would hunt me down and silence me."
The "Enter Sandman" band will perform near the heliport of the continent's Carlini Argentine Base and fans from Argentina, Chile, Colombia, Costa Rica and Mexico will sail in on a cruise ship as part of a Coca-Cola Zero contest.
The cruise will set sail from Tierra del Fuego, the southernmost tip of South America, on Dec. 3.
Announcing the news officially online on Thursday, the rockers wrote, "After 30 years as a band, we have been unbelievably fortunate to visit just about every corner of the earth… except for one. That is all about to change as we are set to travel to Antarctica.
"We'll be playing inside a dome on the base and in another twist, the show will be transmitted to the audience via headphones with no amplification… a real first for us."
The concert will also stream live for the band's Latin American fans and will be filmed for audiences elsewhere to watch at an unspecified later date.
It's only the second concert to take place in Antarctica – Nunatak, an indie-rock quintet comprised of members of a science team investigating climate change, performed in front of 17 people in 2007.

Cyclones Ready for Gopher Invitational
MINNEAPOLIS, Minn.- The Iowa State tennis team continues its fall slate this weekend as it heads to Minneapolis to compete in the Gopher Invitational. The Cyclones will see action from 10 other schools this weekend including Minnesota, South Dakota, UNI, Drake, Eastern Michigan, Wisconsin, North Dakota, South Dakota State, Gonzaga and Iowa.
The tournament will be the first taste of collegiate tennis action for Iowa State's freshmen, Samantha Budai, Talisa Merchiers, and Lydia Green, who did not play at last weekend's Drake Invitational. Head coach Armando Espinosa is excited to see what these players will bring to the table this weekend.
"It is going to be interesting watching them play their first collegiate matches," Espinosa said. "I think there will be some nerves involved there but I want to see them compete and most importantly see what we can do in doubles with them."
Doubles proved to be more difficult for ISU last weekend at the Drake Invite with juniors Ksenia Pronina and Caroline Andersen falling in the second round, while sophomore Ana Gasparovic and junior Meghan Cassens were eliminated in the semifinals of their bracket. The team is anxious to see how the newcomers can help out in doubles play.
"Doubles, again this year, is going to be a very crucial point for us in matches," Espinosa said. "Hopefully we can start to narrow down who we are going to play in the spring in doubles from those three freshmen."
Pronina captured first place in the top flight, going 3-0 en route to the title. Gasparovic earned a runner-up finish in the second flight.
Tournament play begins Friday at the Baseline Tennis Center. First round doubles will begin at 9 am.
"M" Flight Singles
Ksenia Pronina (ISU) vs. Diana Tokar (UW-M)
"U" Flight Singles

I need to address the issue of having zimbra accounts named like 'uid@domain' associated to mail addresses like givenName.lastname@domain.
I've built an alias file from our global ldap server with entries like this :
givenName.lastname: uid
I've tried to change the postfix parameter 'alias_maps' but it does not seem to be the right place for this. I wondered if I could get it working by changing "virtual_alias_maps".
I've read the change should be done upon /opt/zimbra/conf/zmmta.cf but what should the change consist of ?
Right now, there is this in /opt/zimbra/conf/zmmta.cf:
I need to get this as a final result in postfix/conf/main.cf :Code:POSTCONF virtual_alias_maps LOCAL postfix_virtual_alias_maps
Does anyone have an idea to help me on this ?Code:virtual_alias_maps = ldap:/opt/zimbra/conf/ldap-vam.cf , hash:/etc/ldap.aliases
Thanks in advance,

The VRX is fitted with a rechargeable Lithium-ion battery. A multi-voltage charger is supplied, and it will recharge a completely flat battery in approximately 3 hours
The battery level is shown in percentage on the main front dry screen.
It is not necessary to power up the VR before you dive. The screen will automatically power up within a minute of exposure to an absolute pressure of 1.3 BAR or greater. Note: This means in practice that if you do a very fast descent the VR compouter may not switch on until you are at depth.
VR Dive computers use a derivative of the Buhlmann ZHL 16 algorithm modified to assimilate the latest thinking in practical micro-bubble avoidance for enhanced decompression safety.
The VRx can also be configured to use our new VHM alogrithm. You will note than on decompression dives, the Buhlmann algorithm will prompt for deep-water controlling stops of 2 minutes in duration. Deep-water stops are recognized by their duration (normally two minutes) and + next to the time. It is important these these stops are conducted correctly for a safe decompression as they help to reduce the problems associated with potential micro-bubble growth during an ascent.
Dive computers calculate decompression based on the inert gas partial pressures. This is the only accurate way to estimate decompression requirements. Decompression computers are an aid to decompression and backup tables and depth/time instrumentation should always be carried.

FORT MYER, Va. (WUSA 9) - Sometimes at the crack of dawn, Jenn Hall hits the road with the Mobile USO. The custom-made vehicle represents USO-Metro on wheels.
The vehicle serves food, fun and support to over half-a-million military families in the Metropolitan area.
The Mobile USO travels on dirt roads and into the "boonies," according to Hall, the Mobile USO Coordinator.
"It's cool to go to places like that. These guys are out there forever...They don't have a lot out there. Their base is very, very, very small," said Hall. The vehicle serves hotdog meals to 25 military installations for USO-Metro.
On a Wednesday, Hall drives to the Indian Head military base in South Potomac, Maryland.
"I love it, I love catering the people. They're very generous, they're very sincere," said Elizabeth Laub, USO Center Coordinator, South Potomac.
"The mobile is key because we are rural. We are very remote. We have no restaurants or services. A lot of the events that go on in metro Washington; these people don't have privy to," said Laub.
Laub and volunteers set up outdoor tables with fresh fruit, cake, cookies, chips and soda.
Meanwhile, Hall serves as hotdog chef and cooks using the built-in oven inside the Mobile USO.
The troops and their families are excited for lunch.
"We like that it feels like that they are wanting to bring something to us when they show up. My husband loves the hot dogs," said Evelyn Honea, wife of Base Command Master Chief, South Potomac.
When Honea and her husband moved here from San Diego in October, 2012, they were looking for a connection with the community.
"So it gives you a feeling of being included in the greater community," Honea added. She happily volunteers and chats with servicemen and their children.
In addition to a lunch, the Mobile USO also raises awareness for community events like Child Abuse Prevention Month and the Month of the Military Child.
"We are recent empty-nesters. And so it does give me opportunity to socialize with other spouses here on base, and come out and spend time. And it has volunteer opportunities, that you know, otherwise wouldn't be here. So it's wonderful because I am more of a social creature! So it's nice to be able to come out," Honea added.
The Mobile USO has logged over 22,000 miles since its creation by Boeing over five years ago.
Every $25 donation to USO-Metro buys 25 hotdog meals for troops and their families. To donate, click here.
NOTE: Gannett Foundation has provided a grant to USO-Metro.

Common sense should prevail over turf and a desire for personal credit. Unfortunately, some of our county leaders seem to have forgotten their basic responsibilities and the needs of the community. Our county finances are very limited.
Until the county is able to provide minimum health coverage for its employees, repair and maintain the county courthouse, and provide medical transportation for our needy citizens, we should not be expending our limited resources on additional facilities without a comprehensive county plan.
A comprehensive county plan would evaluate the need for another storm shelter. If another storm shelter is needed, let's consider it as a pat of a list of county priorities and let's build it on higher ground on the present county property by the community center at much lower cost.
Storm shelter projects are eligible for federal and state assistance. We should fully explore the availability of grant assistance before committing our precious local tax dollars.
With factual information and a community-based list of priorities, our leaders can make better decisions on the use of our resources.
