Technology plays a key role in teenage romance from initial encounters to eventual break-ups, says a US study.
Teenagers rarely meet online but do use technology for flirting, asking out, meeting up and parting, American think tank, the Pew Research Center, found. A survey of 1,060 US teenagers aged 13 to 17 revealed that technology brings them closer but also breeds jealousy.
"Digital platforms are powerful tools for teens," said Amanda Lenhart, lead author of the report from Pew. "But even as teens enjoy greater closeness with partners and a chance to display their relationships for others to see, mobile and social media can also be tools for jealousy, meddling and even troubling behaviour."
Digital romance, broken down
Of the 1,060 teenagers surveyed:
• 35% said they were currently dating and 59% of that group said technology made them feel closer to their partner
• For boys who were dating, 65% said social media made them more connected to a significant other while it was 52% for girls
• 27% of dating teenagers thought social media made them feel jealous or insecure in relationships
• 50% of all teens surveyed, dating or not, said they had indicated interest by friending someone on Facebook or other social media and 47% expressed attraction by likes and comments
• Texting is king - 92% of teens who were dating said they texted a partner, assuming the partner would check in with "great regularity"
• Jealousy happens, but not as much as flirting does - 11% of teenage daters reported accessing a partner's online accounts and 16% reported having a partner asking them to de-friend someone
What gets discussed during all those frequent social media enabled check-ins? According to the survey, it is mostly "funny stuff" followed by "things you're thinking about" as well as other Information such as where they are and what their friends have been doing. And forget having to meet up to resolve a conflict - 48% of dating teenagers said that could be done by texting or talking online. Online tools, with their accessibility and ease of use, also showed some signs of giving this group relationship anxiety. Females are more likely to be subject to unwanted flirting and 25% of teenagers surveyed said they have blocked or unfriended someone because of uncomfortable flirting. And 15% of teenage daters said a partner had used the internet to pressure them into unwanted sexual activity.
'More than emojis'
Nearly half the respondents admitted to concentrating on their phone ahead of their partner when together with 43% of dating teens saying that had happened to them. "I don't think this survey reveals much that is surprising. But it is affirming. Humans are social animals and we build tools to connect with each other, "wrote Julie Beck, an associate editor at The Atlantic news site, of the survey's findings.
"It's not all heart emojis all the time, no, but the tools that facilitate relationships facilitate all aspects of them, good and bad.
"Connecting with others is scary, hard, sometimes dangerous, but usually, hopefully, good. The teens get it."

Smart Greenhouse
Control the light, watering, temperature, and humidity of your greenhouse – automatically.
Kevin Farnham
Smart Greenhouse, one of three professional category winner in the 2014 IoT Developer Challenge, is an Internet of Things (IoT) device and application that monitors and controls a greenhouse environment. The concept for Smart Greenhouse came into being after the core team – Dzmitry Yasevich, Pavel Vervenko, and Vladimir Redzhepov – attended JavaOne Russia in April 2013. There, the team saw presentations of a smart house, various robots, and other devices, all controlled by Java.
Yasevich notes, “We were impressed by these solutions and had an idea to do something like that. Pavel Vervenko suggested making an automated greenhouse. Everyone liked the idea!”.
First, the team selected the hardware. “We started to use Raspberry Pi as a basis”, Yasevich says. “It is a compact but fullfedged computer with 700 MHz and memory at 512 MB. This system costs around $35”.
However, early on, a safety concern arose. “Current under high voltage passes in the greenhouse, and there is an automatic watering system, so it was necessary to properly consider all the aspects related to insulation”, Yasevich says.

Teaching English as a foreign language teacher: job description
Teaching English as a foreign language (TEFL) involves teaching adults and children whose first or main language is not English. This can be done in the UK or abroad and the students may be learning English for either business or leisure reasons.
Teaching English to speakers of other languages (TESOL) is also a widely used term and often means the same thing as TEFL. It’s sometimes specifically used to refer to teaching English to people who are living in the UK but who do not speak English as a first language. These students are most commonly refugees and immigrants and need to learn the language in order to help them settle into the UK society.Their courses are often government funded.
Teaching English as a second language (TESL) or teaching English as an additional language (TEAL) may also be terms that are used but they generally all refer to the same thing - teaching English to someone whose native language is not English.
Teachers of English as a foreign language can work in a variety of settingswith different age ranges. This can include commercial language schools, schools and institutions of further and higher education throughout the UK and overseas. Some may also teach in industry, while others are self-employed. Classes are usually taught in English, evenwith beginners. Teaching English as a foreign language teacher: job description

Anxiety Medication: Over Prescribed and
Causing Overdoses
According to a story on NBC New York, more and more patients are ending up in New York City hospitals having over dosed on Xanax. Xanax is in the benzodiaziepine family of drugs and it’s used to treat anxiety, nervousness, and panic attacks by decreasing brain activity.
Xanax Overdoses Way Up
NBC New York reports:
Between 2004 and 2009, New York City emergency room visits involving Xanax and other anti-anxiety prescription drugs known as benzodiazepines increased more than 50 percent. That’s up from 38 out of 100,000 New Yorkers in 2004 to 59 out of 100,000 New Yorkers.
It’s not the drug by itself that causes the overdoses, but used in combination with other drugs and alcohol, it creates a toxic cocktail which isn’t easily metabolized in the body.
The drug is habit forming and withdrawal symptoms can include sweating, shaking, difficulty falling asleep, difficulty concentrating, depression, and nervousness. Many fear that the drug is being over prescribed.
“I don’t believe they take the time with the patients to figure out what the problems are,” Cali Estes, a drug counselor said to NBC New York. “A doctor who is running short on time and nurses and probably isn’t paid as much as he or she used to be finds it easier to say, ‘OK, this person has a problem, here’s your script, have a nice day. Where’s my next patient?’”
Whitney Houston’s Death Tied to Xanax and Other Drugs
Whitney Houston’s recent death is raising questions as to this and other sedatives. Xanax is most often criticized by those in the psychiatric community because it only lasts 6 to 20 hours.
Forbes reports:
On the face of it, this seems like a great combination – you get a quick hit of anxiety relief and the drug leaves your system within a 24-hour period. But in practice what often happens is that because the drug acts so quickly and dissipates quickly, the patient begins taking more of it to maintain the effect. Two pills a day turns into four, which turns into six and so forth.
According to the CDC, prescription drug overdose is now the leading cause of accidental death in the U.S., topping automobile accidents for the first time in 30 years. Currently, Xanax is the 11th most widely prescribed drug in the nation.

Lawsuits claim Knoedler made huge profits on fakes
For more than a dozen years the Upper East Side gallery Knoedler & Company was “substantially dependent” on profits it made from selling a mysterious collection of artwork that is at the center of a federal forgery investigation, former clients of this former gallery have charged in court papers. The analysis is based on financial records turned over as part of a lawsuit against the gallery filed by Domenico and Eleanore De Sole, who in 2004 paid $8.3 million for a painting attributed to Mark Rothko that they now say is a worthless fake. The Rothko is one of approximately 40 works that Knoedler, which closed last year, obtained from Glafira Rosales, a littleknown dealer whose collection of works attributed to Modernist masters has no documented provenance and is the subject of an F.B.I. investigation. Between 1996 and 2008, the suit asserts, Knoedler earned approximately $60 million from works that Ms. Rosales provided on consignment or sold outright to the gallery and cleared $40 million in profits. In one year, 2002, for example, the complaint says the gallery’s entire profit — $5.6 million — was derived from the sale of Ms. Rosales’s works. “Knoedler’s viability as a business was substantially — and, in some years, almost entirely — dependent on sales from the Rosales Collection,” the De Soles claimed last month in an amended version of the suit they filed this year. While the forgery allegations are well known and have been the subject of three federal lawsuits against Knoedler, the recent filings expand the known number of Rosales artworks that were handled by the gallery, which was in business for 165 years, and assert that they played a pivotal role in the gallery’s success. After the F.B.I. issued subpoenas to the gallery in the fall of 2009, Michael Hammer, Knoedler’s owner, halted the sale of any Rosales works. Knoedler ended up losing money that year and in 2010, the court papers say. http://www.nytimes.com/2012/10/22/arts/design/knoe...

The underlined bold words are
The x2 is an experimental helicopter being developed by Sikorsky, an American company, which hopes it will be zipping along at more than 460kph. The company, however, is interested in more than just breaking speed records. It plans to use the technology developed for the x2 in commercial helicopters.
Sikorsky reckons that future helicopters built using the x2 technology would be extremely versatile machines. They would dash to and from a medical emergency a lot faster. They would also be very agile in flight, which would increase their capabilities in combat.

Can I help reduce energy consumption?
We have an important role to play right now. Energy conservation helps a lot in preserving our planet’s rich natural resources and promoting a healthy environment. Here you will find simple things that you can do to help reduce energy consumption.
· Turn–off non-essential lights and appliances. The electricity generated by fossil fuels for a single home puts more carbon dioxide into the air than two average cars.
· Avoid turning on large appliances such as washers, dryers, and electric ovens during peak energy hours: from 5:00 am to 9:00 am and 4: pm to 7:00 pm.
· Install white window curtains to reflect heat away from the house. Close them at night to reduce the amount of heat lost through windows. People who live in countries that have warm climates should do this during the day as well.
· Turn off the lights in any room you are not using and consider installing timers, photo cells, or occupancy sensors to reduce the amount of time your lights are on.

WASHINGTON — Getting blood or other perishable supplies to an area that’s been struck by an earthquake or hurricane isn’t as simple as asking what brown can do for you. But a new model quickly determines the best routes and means for delivering humanitarian aid, even in situations where bridges are out or airport tarmacs are clogged with planes.
The research, presented February 18 at the annual meeting of the American Association for the Advancement of Science, could help get supplies to areas which have experienced natural disasters or help prepare for efficient distribution of vaccines when the flu hits.
Efficient supply chains have long been a goal of manufacturers, but transport in fragile networks — where supply, demand and delivery routes may be in extremely rapid flux — requires a different approach, said Anna Nagurney of the University of Massachusetts Amherst, who presented the new work. Rather than considering the shortest path from one place to another to maximize profit, her system aims for the cleanest path at minimum cost, while capturing factors such as the perishability of the product and the uncertainty of supply routes. ‘You don’t know where demand is, so it’s tricky,’ said Nagurney. ‘It’s a multicriteria decision-making problem.’
By calculating the total cost associated with each link in a network, accounting for congestion and incorporating penalties for time and products that are lost, the computer model calculates the best supply chain in situations where standard routes may be disrupted.
‘Mathematical tools are essential to develop formal means to predict, and to respond to, such critical perturbations,’ said Iain Couzin of Princeton University, who uses similar computational tools to study collective animal behavior. ‘This is particularly important where response must be rapid and effective, such as during disaster scenarios … or during epidemics or breaches of national security.
’ The work can be applied to immediate, pressing situations, such as getting blood, food or medication to a disaster site, or to longer-term problems such as determining the best locations for manufacturing flu vaccines. . Retrieved April 7th, 2011.
