(EsPCEx - 2015) 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. Its a way for kids to get a hands-on understanding of what their parents do when they are separated from them during deployments.

(EsPCEx- 2015) Were so well educated but were 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 weve 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. Todays 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 dont 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 isnt 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.

(EsPCEx - 2015) Desde 2007, o saldo comercial brasileiro vem apresentando tendncia de queda, puxada pelo mau comportamento do setor industrial, e em consequncia da perda da competitividade da economia brasileira (Fonte: oglobo.globo.com/opniao/comercioexterior Consulta em 26/03/2015). A perda sistmica de competitividade da indstria nacional e a consequente queda de sua participao na formao da riqueza nacional esto associadas, dentre outros: I. aos elevados custos de deslocamento dos produtos de exportao, em virtude do predomnio das rodovias e da precria integrao entre os modais de transporte. II. grande disperso espacial da indstria brasileira em regies historicamente perifricas. III. baixa taxa de inovao da indstria brasileira, aliada ao fato de essa inovao estar mais relacionada aquisio de mquinas e equipamentos do que ao desenvolvimento de novos produtos. IV. aos inmeros acordos bilaterais assinados pelo Pas, restringindo o nmero de seus parceiros comerciais no mercado externo. V. fraca mecanizao das operaes porturias de embarque e desembarque e intricada burocracia nos portos, provocando atrasos e congestionamentos nas exportaes.
