Q616990 Inglês
We’re so well educated – but we’re useless

    Record numbers of students have entered higher education in the past 10 years, but despite being the most educated generation in history, it seems that we’ve grown increasingly ignorant when it comes to basic life skills.
   Looking back on my first weeks living in student halls, I consider myself lucky to still be alive. I have survived a couple of serious boiling egg incidents and numerous cases of food-poisoning, probably from dirty kitchen counters. Although some of my clothes have fallen victim to ironing experimentation, I think I have now finally acquired all the domestic skills I missed out in my modern education.
  Educationist Sir Ken Robinson says that our current education system dislocates people from their natural talents and deprives us of what used to be passed from generation to generation – a working knowledge of basic life skills. Today’s graduates may have earned themselves distinctions in history, law or economics, but when it comes to simple things like putting up a shelf to hold all their academic books, or fixing a hole in their on-trend clothes, they have to call for help from a professional handyman or tailor.
   Besides what we need to know for our own jobs, we must have practical skills. We don’t grow our own crops, build our own houses, or make our own clothes anymore; we simply buy these things. Unable to create anything ourselves, what we have mastered instead is consumption.
  Sociologist Saskia Sassen argues that the modern liberal state has created a middle class that isn’t able to “make” anymore. I suggest that we start with the immediate reintroduction of some of the most vital aspects of “domestic science” education. Instead of only maths, language and history, we should create an interactive learning environment in schools where craftsmanship and problem-solving are valued as highly as the ability to absorb and regurgitate information. We need to develop children into people that not only think for themselves, but are also able to act for themselves.

Children experience basic training and mock deployment

    The 460th Force Support Squadron (FSS) hosted the 6th Annual Operation Future Forces (OFF) Sept. 13, 2014, at Camp Rattlesnake. OFF allows children ages 8-18 to experience what military members endure from basic training to technical school to a mock deployment, ending with a homecoming party.
  “The youth mock deployment was developed to alleviate many of the stresses commonly experienced by young family members when one or both parents are deployed,” said Thomas Cox, 460th FSS youth program chief. “Everything from basic training, tech schools, camp activities and accomplishing their mission as a team made the event a one of a kind opportunity for military kids.”
   A few of the boys had their heads shaved before heading off to “Basic Military Training.” The training consisted of doing push-ups and sit-ups, jumping through hula-hoops and running through an inflatable castle. They were also taught how to stand at attention, salute and do an about-face.
    After basic training, each child attended “technical school” and was taught a specific Air Force Specialty Code to help them in their mock deployment. Some children were taught lifesaving self-aid and buddy care skills while others learned about the importance of radio communications while on a deployment.
   The tech-school graduates were then issued water pistols before heading out. During their deployment, the children encountered hostile and non-hostile citizens, a water-balloon fight and injured allies who needed help along the way.
   At the end of a long day, loved ones waited outside the youth center on base with homemade signs welcoming the “troops” back home.
   “This event was great,” said Senior Airman Jasmine Madison, 460th FSS Force Support Force Management technician. “It’s a way for kids to get a hands-on understanding of what their parents do when they are separated from them during deployments.”

Frequently Asked Questions – Instagram

   What is Instagram?
   It's an application for your mobile phone that enables you to edit pictures you have taken with your mobile phone camera using built-in filters and share them with others. If you have an Instagram account you can tag pictures, rate and comment on other people's pictures and follow other users.
   How much is your app?
   $0.00.
   Where does the name come from?
   When we were kids we loved playing around with cameras. We loved how different types of old cameras marketed themselves as “instant" - something we take for granted today. We also felt that the snapshots people were taking were like telegrams in that they got sent over the wire to others - so we figured why not combine the two?
   How did the idea come about?
  We love taking photos. We always assumed taking interesting photos required a big bulky camera and a couple years of art school. But as mobile phone cameras got better and better, we decided to challenge that assumption. We created Instagram to solve three simple problems:
  - Mobile photos always come out looking mediocre. Our awesome looking filters transform your photos into professional-looking snapshots.
  - Sharing on multiple platforms is a pain - we help you take a picture once, then share it (instantly) on multiple services.
  - Most uploading experiences are clumsy and take forever - we've optimized the experience to be fast and efficient.
   How does privacy work?
 We have adopted a follower model that means if you're “public" on Instagram, anyone can subscribe to follow your photos. We do, however, have a special private option. In this mode, a user can make sure he/she must approve all follow requests before they go through.
   Who can see my photos?
   All photos are public by default which means they are visible to anyone who has an account. If you choose to make your account private, then only people who follow you on Instagram will be able to see your photos.
