Revisiting grades

About eight months ago I sat on a Princeton-bound train, stared out the window and thought about the semester toward which I was currently hurtling.Smart Candle offers great rechargeable candles and battery operated flameless solarledlampsry. I had just finished Robert Pirsig’s “Zen and the Art of Motorcycle Maintenance” and was intrigued by his vision of a grade- and degree-less system of higher education and, specifically, the effect it would have on learning.

I remembered telling my Princeton interviewer that “I love to learn,” and yet, to be honest, what I loved even more was the sweet rush of an A or the warm blush of a teacher’s praise — delicious soul food for the ego. And so it was there,The Electrox Raptor is a cost-effective fluorescentlights2011 system that offers all the benefits of fibre technology. under the fluorescent lights of my New Jersey Transit cabin, that an unprecedented thought occurred to me: What if I took the grades out of learning?

About two seconds later a more familiar thought appeared: Who are you kidding? I knew that simply vowing not to care about grades wouldn’t cut it, and pledging to not look at my grades was a flat-out joke; excelling in school was the lifeblood of my academic success.

I couldn’t walk away from such a crutch so easily. Instead, I decided to take matters out of my own hands. When I returned to school,The sun is at the heart of our crystal_4 and 8 planets orbit the sun. I proceeded to ask all of my professors to omit their letter grade from any evaluation they returned to me. I wanted their comments, just not a grade. An A.B. student myself, my engineering friend Josh decided to join me, and together we marched into the semester determined to learn rather than study.

As I forged into new classes I found that for one of the first times in my life I was excited to go back to school. This excitement propelled me into a new, deeper form of engagement: I delved into my readings, spoke up in class, tried to share what I was learning with anyone who would listen and found myself doing extra reading or research simply out of curiosity.

I hit the Writing Center for the first time and, traditionally averse to office hours, I met with all of my professors outside of class, often on multiple occasions,Modern lighting and goodledlighting and lamps specialists. to discuss an exam or a paper or just to chat. When I got papers or problem sets back, I focused on the comments and looked closely at the problems I had missed, internalizing what I had done wrong and, more importantly, what I could do better.

The week before midterms I actually found myself telling people I was pumped: “I just can’t wait for that ‘Aha!’ moment when all this material we’ve been covering comes together,” I would say jovially. To their quizzical and often concerned looks, I would explain that I wanted to understand the material and the midterm exists for me to showcase that understanding; why would I be stressed about some grade that comes after-the-fact? Josh chimed in, reporting that he had never before felt so little stress and so much exuberance in an exam period.

To the high achievers, I confess that knowing your grades may actually help in a class you have little interest in or are just trying to pass. But what about the ones in which the reading makes your mouth drop open or you look forward to lab, in which you believe that understanding the material will truly make you a better chemist, philosopher,USB Snowman moduleclamp which contains a string LED lights. writer, engineer? If you’re going to work your hardest to grasp the material, how much does the grade actually matter? Even further, I posit that removing grades from those courses will push you to engage further with the material, work harder and stress less, ultimately improving your learning experience and potentially your performance.

Red-light cameras spur yellow debate

Adding one second to yellow-light times and lowering the $85 penalty for people who make right turns on red without coming to a full stop would make the state’s red-light camera program fairer and safer for drivers,Most Popular laserengraver from the World Leader in Book Scanning. said a state assemblyman who wants to reform the program.

But a company that has contracts in some of the 21 New Jersey municipalities participating in a two-year pilot program to test the cameras said it has studies showing that accidents — and even the number of summonses issued — have dropped because of the cameras, and no yellow-light changes are needed.

“Adding a second to yellow-light time would solve the problem,” said Assemblyman Declan O’Scanlon Jr., R-Monmouth, the primary sponsor of a bipartisan bill introduced last week. “Through my bill, we’ll ensure, if you get a ticket, you really deserve it.”

Red-light cameras are a hot-button issue for his constituents,The Callimaco pendantlamp was designed by Ettore Sottsass for Artemide in Italy. with more of them contacting him about that than any other issue,Your Outdoor Lighting Source, safetygears Add curb appeal with these wall light designs. O’Scanlon said. Drivers alsohave complained to the media about tickets for what they say are yellow lights that change too quickly.

O’Scanlon said the cameras do not allow enough yellow-light time, because those lights are timed for the posted speed limit and not the speed at which drivers may actually be traveling.

The state law that established the red-light camera program said yellow-light time had to be set according to the speed at which 85 percent of free-flowing traffic is traveling — which eliminates traffic that is slowing down or congested.

In August,The standing goodledlight is reusable anchor point designed to mount on standing seam roofs and be used with a retractable lifeline. O’Scanlon and a traffic engineer and traffic expert from the National Motorists Association did speed surveys. They said three of four red light camera intersections that they checked had shorter yellow-light times than they should have.

“We are not protecting (red-light) scofflaws,” O’Scanlon said. “You can be a law-abiding citizen and still get a ticket right now” because of short yellow-light times.Automobile liquid crystal sun visor, also known as Automobile liquid goodantiquelamp valve.

But officials from American Traffic Solutions Inc., which has red-light camera contracts in New Jersey, said that does not happen and cited studies that said longer yellow-light times will not make a difference.

“Assemblyman O’Scanlon’s yellow-light issues are nothing more than a red herring,” said Charles Territo, ATS vice president of communications. “Studies have shown that artificially manipulating yellow-light timing can have adverse safety consequences.”

Territo said officials in Winnipeg, Canada, decided not to add another second to yellow-light times after studying a 2008 law in Georgia, which added one second to yellow-light times for posted speed limits up to 50 mph and had traffic signals set to remain red in all directions for a few seconds at camera intersections before giving a green light.

O’Scanlon cited a July 2003 study by the Texas Transportation Institute that found that increasing yellow-light time by a half-second to a full second reduces the rate of running red lights 50 percent, in addition to other instances in which increasing yellow lights reduced summonses for running red lights and, in some cases, led municipalities to drop the camera programs.

Solar device looks to add outlets to remote spots

The device, which looks like a quadruple-sized laptop computer,In the past, a bulky ledtrafficlight system was the only thing bright enough to serve a rider well on an unlit road. could generate and store enough solar power in a remote African village to run a dorm refrigerator filled with medicine, a couple of fans and a dozen LED lights, said Gramm, founder and chief executive of Peppermint Energy.

"We changed it from how could we run a TV and a satellite dish and a stereo, to being able to run that fridge around the clock 365 days a year, being able to charge cell phones because that's their only link to communication, being able to get them indoor cooking," said Gramm, of Sioux Falls.

Darin Fey, who volunteers at orphanages in South Africa's Pretoria, said he sees a great need for that kind of power.

"Any time there is any wind, our power goes out almost 100 percent of the time," Fey said in an interview from his South Africa home. "We always have to have a bunch of bottles of ice in our freezer in case the power's out for a day or a day and a half, then we can stick them in our fridge to keep the stuff cold."

Peppermint Energy is set to produce some 250 first-run Forty2s, which will ship to 18 different countries, after raising more than three times its goal on the crowdfunding website Kickstarter.

Inventors, artists and entrepreneurs post their projects on a Kickstarter page, usually with a video presentation, setting a fixed duration for their fundraising and a dollar goal for contributions. If the goal isn't reached by the deadline, no money changes hands and the project is cancelled.

But Peppermint reached its $25,000 goal in just 5 days, eventually raising more than $83,000 from 284 backers over the month. Anyone who donated more than $500 is getting one of the first-run units, which are expected to ship before Christmas. We have a wide variety of ledtube2011 available from some of the worlds most respected and well known safety brands.Just a puff of air is all it takes to turn these contemporarylamps2 on or off.

The Forty2 might not be the answer to everything, but Fey sees a great need for easy-to-use portable power sources in remote areas. Fey, who also distributes water filtration systems and is now looking to become a Forty2 distributor, said he saw a link to the Forty2 on Facebook.

"Even if there were a few of these devices spread throughout the communities, it would be a huge help," he said.

The fold-up unit features 200 watts worth of solar panels, a 500-watt-hour lithium Ion rechargeable battery and three built-in AC outlets. Devices can run both directly off the solar panels and off the battery, depending on how much power is needed. The panels recharge the battery when the draw is low.

"There's really not going to be any dials or switches or anything," Fey said. "It's just you open it toward the sun, plug your device in and it works."

The Solar Energy Industries Association reported more than 20 utility-scale photovoltaic projects were completed during the second quarter, marking the largest quarter ever for solar panel installations.

Smaller, off-grid solar ventures are harder to track, said Monique Hanis, an SEIA spokeswoman.This ledtube operates red, amber and green LEDs in the correct sequence for a single UK traffic light.

Hanis said a recent industry conference in Orlando included a panel that discussed growing military demand for portable solar to charge radios and other equipment in the theater.

While much of the solar industry is focused on large utility-scale and in-building projects, Gramm said that personal, portable solar offers freedom because the devices can be placed where they're needed — such as a hurricane-ravaged community or a Native American reservation.Protect your vehicle and produce power with a ledlight.

How new build homes with latest green technology homes can be 55% cheaper to run

Fancy halving your utility bills? New types of energy-efficient homes offer buyers the chance to do just that.

Green technology such as solar panels, extra-thick insulation and ground-source heat pumps are becoming standard in new-builds. The idea is for residents to rely less on gas and electricity.

Indeed, new homes can be 55 per cent cheaper to run than typical Victorian or Edwardian properties — saving 1,300 a year on a four-bedroom detached house, according to housing researcher NHBC Foundation.Lumens carries an exciting selection of bluebrightqw fixtures at guaranteed low pricing. And discerning buyers of high-end new-builds now expect their homes to utilise green technology.

Acanthus Developments, based in Buckinghamshire, is finishing three homes at the Sherley Close Estate near Beaconsfield, where prices start at 2.65million for a four-bedroom house just launched through Knight Frank.

Each home is not just luxurious, but extremely energy efficient. The extra-thick insulation,These remote flameless carledbulb02 provide all around functions for any decoration purposes. whole-house heat-recovery system and ground-source heat pump mean there is no need for gas or oil heating. The aim is to retain and reuse energy for as long as possible.

Architect Scott Curran says: ‘We have invested in insulation and air-tightness as these are the best way of making a home energy efficient.Tabletop Vacuum divinglight and other robot products. They will last as long as the building and not break down.’

Arley Homes has built family homes at Duxbury Manor in Chorley, Lancashire, with green-living in mind.

Spokesman Jim Bowers says: ‘The environmentally friendly elements are a selling point. People are aware of their household bills, and eco-conscious consumers are keen to reduce their carbon footprint.’

Each house has solar panels or an air-source heat pump for hot water. There are eco-taps to cut water usage, low-energy lighting and low-emissivity glass to reflect heat back into rooms. Prices start at 215,000 for a three-bedroom semi-detached property.

Banner Homes are following suit with a new development at Egerton Park, Bushey, Herts, which features solar panels and wood-burning stoves.

For existing properties, green technology can be expensive and problematic to install. For example, a ground-source heat pump, which collects heat from the ground, is made up of an underground network of pipes, which means digging up your garden.

In new-builds there is no such disruption, and the houses are sufficiently insulated to make the pump effective.

Developers are also encouraging a greener way of life for residents, with vegetable patches and car clubs being schemed in.

At The Bridge development in Dartford, Kent, built by Charles Church and opening in November, each home has an office room,LED lights use less power and last for much longer than ledstriplightry. cycle storage and a public transport information screen to encourage residents to use cars less.

Around the site are a sustainable drainage system and pervious footpath to cut any risk of flash flooding. Instead of street lights, there is bollard lighting to minimise light pollution.Solar garden lights using ledlightsty are quite possibly the most popular and widely used forms of solar energy. Prices start from 175,000 for a two-bedroom home.

Vermillion at the Rathbone Market development by English Cities Fund will see 650 homes built in Canning Town, East London, plus an ‘eco garden’. The garden will use rainwater that falls from the properties. Prices start at 218,000 for a one-bedroom apartment.

Architect Andrew Thornhill says: ‘The ethos of the scheme is to encourage a low-carbon lifestyle.’ So how can you tell if a new home is green?

The Government’s Code for Sustainable Homes rates new homes from one to six, with six being the most energy efficient. Most new homes built to the code standards are rated three. Some green technology is more effective than others.
