Videos teach faculty, students how to react in campus shooting

In an effort to further protect University staff and students from potential harm, ASU Police have posted safety-training videos through Blackboard, providing instructions on what to do during various emergency situations, including encountering a shooter on campus.

The Center for Protection and Personal Safety produced and marketed the video presentations to college campuses, corporations and government agencies across the U.S.

Senior account executive Steve Warren said Randy Spivey, the company's CEO and former hostage survival program director for the U.S. Department of Defense, started the company to educate people on safety issues.

"He started his own company really as an effort to educate and power individuals to be safe," Warren said.

There are six videos viewers may choose, each ranging between 18 and 22 minutes. Topics of the videos include what to do when shots are fired on campus, preventing violence in the workplace and how to stay vigilant when escaping a shooter on campus.

"Essentially it talks about warning signs for potential violence, things to look for, actions to take in the event of an emergency, things to consider in terms of evacuating or sheltering in place (and) getting out of that type of situation," Wilson said.

Library specialist Christina Peck, who works at the Tempe campus Noble Science Library, said the most important thing she learned from watching the videos was to stay calm and not panic.

"If something like that were to happen, most people would start to panic and that's the worst thing you could do," she said. "So you need somebody that's calm to be like, ‘OK, we need to get out or go to a secure place.'"

According to various media reports, panic among students and faculty was prevalent in the case of the Virginia Tech shooting in 2007. Some students were unaware of a shooter even on campus.

Virginia Tech student Seung Hui Cho killed 32 people on the Blacksburg, Va., campus before taking his own life.
Finance junior Daniel Becker said he wouldn't know what to do in a similar situation other than go on with his day unless the action is directly in front of him.

Becker said his first instinct would be to, "probably contact my friends, see where they are, see if they're (near the shooting)," he said. "If I'm supposed to stay in a building, I'll stay in a building, if I'm supposed to leave campus, I'll leave campus."

According to the safety video "Shots Fired On Campus," the odds of being involved in a campus shooting are the same as being struck by lighting.

On Nov. 3 David Huynh, 36, fired a single shot from his handgun at students hanging out at the volleyball courts on the West campus. No one was harmed.

The ASU community was notified a short time after the shooting via the University's alert and advisory system, which sends out text messages to students. The alert system is used in emergency situations, and students and faculty must be registered to receive the alerts.

The "Shots Fired On Campus" video advises students in a shooter situation to silence their cellphones and other noises around them after receiving the news or alerts of the emergency.

Nordic Center yurts: Rustic in the round

After the birth of our daughter Grace and then son Ezra, we found ourselves backpacking and camping less. The yurt gave us a chance to try our hand at quasi-camping, where we hauled gear in backpacks but did not have to worry about a tent or water. And, we were not alone in this notion: the guests of the other yurt were a young Phoenix couple and their 16-month-old daughter, Sophie.

We also enjoyed the distinct advantage of a woodstove-heated space -- a bonus to the yurt that also helps extend the camping season well into the fall. In fact, the yurts are a year-round offering and a popular overnight retreat for cross-country skiers and snowshoeing enthusiasts.

Like our nights of tent camping, the yurt served primarily as our base of operations to explore. The Nordic Center yurt experience is enhanced by the more than 30 miles of trails. While the trails are there primarily for the cross-country ski season, they also offer hiking opportunities.

Following a dinner that included veggie burgers and roasted corn, my sister-in-law showed off her fire-starting skills by getting a nice blaze going in the fire pit. We basked in the campfire as the dusk went blue and the stars began to show. The woodsmoke, emerging night and mountain air helped us reconnect with all the things we loved about camping.

As we prepared for bed, I found myself fixated on one interesting feature of the yurt: A perfect circle of a skylight about two feet in diameter at the top of the ceiling. During the day, this brings light into the room, along with two windows that can be unclipped and rolled up.

At night, the dome creates a small window into the cosmos.

For the time of our visit, I could see Orion's Belt in the circle. Johnson notes that, during the winter, the Big Dipper is visible in circle, and people who stay overnight can watch it rotate through the night.

In many ways, it reminded me of a crude version of a James Turrell Skyspace, where the minimalist conceptual artist reveals a circle of sky in the center of a room so people can watch and interpret the sky's color and form. To this effect, I watched how dawn faded out the stars and brought different shades of blue in the circle.

The morning brought a robust hike up the Abineau Trail and across a trail known as the Snowslide. While most of the forest remained in shadow, Kendrick Peak to the west was bathed in morning light.

As I pulled the crisp air into my lungs and studied the cool and warm tones of morning and the emerging light, I realized that we needed to refill our summer season with family camping and look to the yurts to help extend the season into the fall and beyond.

Right On

Right On
Notice how expensive light’s going to be getting, I point out in Thursday morning’s Journal Sentinel: Bulb makers say they’re close to perfecting the LED bulb for household use that can replace the 100-watt incandescent bulb, which is more or less illegal as of next year. The LED bulb would cost, at least at the outset, about $50.

In what world does a $50 light bulb for household use make sense? One where the government makes the cheaper alternatives scarce. Congress knocked out 50-cent incandescent bulbs as part of a 311-page law passed in Nancy Pelosi’s first bloom of power and signed – gee, thanks, pal – by President George W. Bush. The ban* approaches unhindered under President Barack Obama and, as I point out, fits right into his plans to nudge us into a “green jobs” utopia. It’s of a piece with Obama’s cap-and-trade-and-Chevy-Volt dreams.

I write:

“In selling all these things, the president speaks of villains who at last will be made to pay: Coal-burning utilities will squirm, oil companies will be discomfited. In place of these baddies, virtuous new industries will be spawned.

“But he makes an elementary error: He sees the $50-per-bulb of revenue to a new lighting industry while never noticing the $49.50 of other things that people would have bought had their government not ginned up a light-bulb crisis. The $50 isn't new money: It's just diverted against customers' will from, say, mustard or dentistry or shoes or motel stays or any of a million things that people would rather spend their money on if the government had let well enough alone.

“Underlying all this is, apparently, a belief that you and I have to get used to less of nearly everything, energy included, and that it's up to policy-makers to nudge us. Take another part of (Rep. Paul) Ryan's plans, health care for future retirees. He proposes a reliable, tested mechanism to bring prices down - market economics. Obama instead proceeds from the belief that we're using too much health care. He proposes an expert panel that will restrict how much care people get, especially of expensive, new treatments.

“On taxes, Obama talks endlessly of more accurately finding out who has too much money - again with the villains! - and taxing away more of it. Ryan audaciously suggests we see how we can all get richer, meaning more money for every purpose - including government, and without the punitive rates.”

Read about a more optimistic alternative here.

*By the way, I know that formally speaking, the Energy Independence and Security Act of 2007 does not ban incandescent bulbs. No, it just insists that any bulb you are permitted to buy should be many times as efficient as incandescent bulbs can be. Clever.

Also, yes, I know compact fluorescents are somewhat cheaper than LEDs. Yes, I know they save money long-term, presuming the kids don’t break them. That’s why I use several around my house, in places where I don’t care that their light is weak and ugly. That doesn’t make it right for the government to boss around your light bulb selection.

Facebook Turns to Smart Lighting for Data Center

Facebook Turns to Smart Lighting for Data Center
Facebook’s new data center in Oregon has gotten its fair share of attention, both for Facebook’s decision to open up the energy efficient design, and also for Greenpeace’s campaign to try to convince Facebook to stop powering it with coal. But here’s another reason to recognize the data center: Facebook has installed a smart lighting system courtesy of startup Redwood Systems.

Sam Klepper, Chief Marketing Officer for Redwood Systems, tells me that Facebook is currently using Redwood System’s technology to control over 1,000 lights in Facebook’s data center in Oregon, and Facebook plans to add the lighting system to the rest of the buildings at the Oregon data center shortly. Klepper says Redwood Systems is also talking to Facebook about implementing the technology in Facebook’s upcoming data center in North Carolina.

Redwood Systems makes lighting digital, networked and intelligent. The 3-year-old company makes a control and sensor system for LEDs (light emitting diodes) that runs over an optimized version of ethernet cables. Commercial building owners and data center operators can use the LED lighting control and management system to cut the amount of lighting used throughout the building, in some cases up to 70 percent over standard non-networked fluorescent lighting systems. LEDs are more efficient than fluorescents, but Redwood’s management system also monitors the building environment, including temperature and room occupancy, and can dim and manage the lights to help maximize efficiency.

Klepper told me that a typical return on investment in terms of energy savings for the lighting system, is between two to five years after installing the system, depending on different factors. Around 40 percent of Redwood System’s customers right now are in the data center space, said Klepper, who added that that percent will likely grow over the coming months and years. Klepper also said that Facebook is interested in the lighting technology partly because it is combining lighting efficiency with overall building intelligence, and Redwood’s sensors can alert managers when panels for hot/cold aisle containment have been left open, or , say, when there is movement in certain sections of the data center.

Redwood uses its optimized communications cables to send both a digital signal (zeros and ones of information) as well as power, and each LED fixture contains an embedded sensor that can monitor the environment of the room. The LEDs are then connected to the centralized Redwood computing engine.

Dave Leonard, co-founder and CEO of Redwood Systems, left Cisco’s wireless division to start the company. The company is backed by at least $27 million from Index Ventures, Battery Ventures and U.S. Venture Partners. There are a variety of competitors that are offering similar lighting management systems, including Digital Lumens, and Adura Technologies as well as offerings from the building automation companies Honeywell and Johnson Controls.

Smart lighting could be a massive market. The Electrical Power Research Institute (EPRI) reported that only 7 percent of the U.S. commercial and industrial market have installed lighting control systems of any kind.

What Light Pollution Ordinances Could Mean for C-stores

What Light Pollution Ordinances Could Mean for C-stores
We all know that well lit c-stores attract more clientele at night. Folks, especially women feel safer in a well lit environment. Indeed, studies and surveys show that it is actually safer, and humans seem to inherently know this. Perhaps, the reasoning has to do with the basic “crime triangle” – that is to say for a crime to occur three things are needed:

A brightly lit convenience store tends to remove the opportunity due to risk/reward for the criminal in that they will most likely get caught, and witnesses will see them and turn them in, therefore they keep going and look for other opportunities, and safer locations to do their criminal activity. That’s why a well-lit facility works.

Now then, with high energy costs, which may, in fact, triple in the upcoming years due to more regulations on coal-fired plants and subsidized alternative energy – keeping a brightly lit facility may be a problem. Perhaps, that’s why more and more of us are going to LED lighting to save both energy and money, and collect some tax breaks to boot.

Nevertheless, there is an on-going battle running in many urban areas and big cities with regards to the proliferation of LED Billboards. The opponents of these billboards have shown that they are highly distracting to motorists and cause more pedestrian, bicycle, and multi-car accidents – the research appears to confirm this, although some of that could indeed be due to the increase of text-messaging while driving, compounded with the billboard distractions – time and more research will tell.

Indeed, there was a very interesting segment recently on KCET Los Angeles News titled “Bright Lights, Big City” by Reporter Judy Muller, Producer Karen Foshay and Editor Alberto Arce, which noted that in the long ongoing battle in Los Angeles’ Westside against LED Billboards there is a new challenge: human health. The segment started with this comment: “Light pollution may be a more serious concern than you think. New evidence suggests that a lack of darkness in our urban night skies contributes to air pollution, making it a matter of public health. Yet Los Angeles keeps rolling out bigger, brighter signs.”

Will local neighborhoods ask convenience stores to also curtail their brightness? Will local governments step in and create more regulations? If so, that will mean fewer sales in the evenings, thus, hurting business. Perhaps fewer patrons will wish to wonder very far from their cars when pumping fuel. Fewer trips into the c-store will mean fewer sales on high-profit impulse items.

Is this a future threat? It very well could be.

For those c-stores who have signed agreements with Billboard Companies sporting large LED Multi-media Billboards, that could cost a few bucks each month in rental or lease revenues from those Billboards in the future. Either way, this could be a future threat to the industry, albeit not a game changer, it might still slightly alter the dynamics and cost your c-store future revenue. I hope you will please consider all this and think on it.

LG Unveils Next Generation Televisions

LG Unveils Next Generation Televisions
LG announced the launch of its 2011 TV range for the Singapore market, delivering cutting edge innovations that promise to transform the way consumers enjoy televisions at home. Featuring LG’s proprietary CINEMA 3D technology and LG Smart TV functions, the new 2011 range will feature 11 series of LED, LCD and Plasma TVs to suit the entertainment needs of every individual, with more to be rolled out throughout the year.

Leading the lineup is the new LG LW6500, a Full HD edge LED CINEMA 3D TV equipped with LG Smart TV. The sleek TV brings 3D enjoyment to a new level with the employment of 3D technology similar to that used in cinemas, thus bringing to consumers greater comfort and convenience while enjoying their favourite 3D titles. With Smart TV, consumers are also able to access content and applications without hassle through a specially designed user interface as well as the new Magic Motion Remote Control that simplifies control with a simple point and click.
LG CINEMA 3D TV – evolution of 3D for homes

Taking 3D to new heights, the LG CINEMA 3D TV looks set to greatly improve 3D experience for home viewers with crisper images and wider viewing angles that was not previously possible with active shutter technology. The use of Film Patterned Retarder (FPR) technology in LG’s CINEMA 3D TVs brings about a more comfortable viewing experience with a polorised plate on the panel, coupled with the use of polarised glasses by viewers. The technology optimises the separation of images for the left and right eye, and the images are then filtered through the glasses to give viewers a better 3D effect with minimal cross talk.

The new LG CINEMA 3D TV is also able to display brighter and clearer 3D pictures than conventional 3D displays with the inclusion of the new Light Boost technology. This brightness enhancement film maximises lighting from LED backlight to maintain the full brightness and picture quality of the original source. Compared to conventional 3D displays, the Light Boost technology is able to deliver brightness of 150 nits, twice of what conventional 3D TVs can deliver, without increasing power consumption. For the reproduction of smoother 3D images, TruMotion 200Hz is featured on the flagship LG LW6500 series, which results in elimination of image blur and enables consumers to enjoy even the fastest action sequences in 3D. Consumers who are worried about the loss of image quality of high-definition content in 3D need not worry with the new LG CINEMA 3D range, as the new TVs are able to ensure no signal loss in Full HD 3D source with LG’s very own 3D picture enhancement algorithm.

A common challenge faced by consumers using active shutter 3D technology is the inflexible viewing positions and limited viewing angles. With LG’s CINEMA 3D TV, consumers can experience 3D images without restrictions on positions as the viewing angle has been increased to 180o horizontally. Users may sit, lean or even lie comfortably on their couches to enjoy true-to-life 3D images, and up to 20 viewers are able to enjoy 3D on LG CINEMA 3D TVs .

For users who find discomfort in viewing 3D on active shutter models, LG’s CINEMA 3D technology delivers a virtually blur-free and flicker-free 3D picture, which reduces the possibility of dizziness or nausea. Also, LG’s CINEMA 3D TVs are the world’s first 3D TVs to be confirmed to deliver flicker free and crosstalk free images by TüV and Intertek. The new LG CINEMA 3D TVs also employ the use of affordable, lightweight polarised glasses that weigh only 16 grams, almost half the weight of conventional active shutter glasses. These glasses do not need to be powered by batteries, helping consumers to save in the long run. Additionally, the LG LW6500 (LG 47LW6500) series with CINEMA 3D has been awarded with the CNET Asia Editor’s Choice Awards for delivering “one of the best 3D performances around” .
LG Smart TV - “Point, Click, Control, Simply Smarter”

Along with LG CINEMA 3D TVs, LG has also rolled out TVs equipped with LG Smart TV technologies. As consumers are growing to be more connected than ever before, LG Smart TVs brings the best of the Internet straight into televisions, so individuals can have access to a wealth of content with simple controls.

Top 5 IBD 50 Tech Stocks By RS Rating Led By Sina

Top 5 IBD 50 Tech Stocks By RS Rating Led By Sina

The IBD 50 looks at many of the “main” factors, such as sales growth and profit growth, in determining the top 50 stocks each week. The list is ranked by what we call our Composite Rating, our most broad-based rating.

The items determining the CR include one of IBD’s key gauges, the Relative Price Strength Rating. The RS is a feature of our stock coverage, and subscribers can easily re-order the IBD 50 by RS (or by many other different ways.)

The RS rates stocks by how they’ve performed vs. all other stocks in the past 12 months, with extra weight given to the most recent three months. It’s showing you the strongest stocks.

In general, IBD advises that you focus on stocks with RS ratings of 80 or above. A stock with an 80 RS has performed in the top 20% of all stocks over the past 12 months. On the other side, you want to be careful with any stocks below 70 RS.

As it turns out, the lowest RS in the current IBD 50 is the No. 50 stock, Oracle (ORCL) , at a 72. All of the other 49 IBD 50 companies have an RS of 77 or higher.

The latest IBD 50 includes just two 99 RS stocks, and both are techs: Sina and Travelzoo. Three other techs have RS numbers of 97 or higher. Here are the top 5 IBD 50 tech stocks by RS ranking, listed by their IBD 50 ranking.

Qatar in spotlight in absence of Arab heavies

DUBAI — The conflict in Libya has swept small but wealthy Qatar into the diplomatic and military spotlight in the absence of traditional Arab heavyweights Saudi Arabia and Egypt, analysts said on Wednesday.

Qatar last week became the first Arab state to take part in Western-led military operations against the regime of Libyan leader Muammar Gaddafi.

It has since scored another regional first by recognising the transitional council of the rebels battling Gaddafi as legitimate representatives of the Libyan people.

On Tuesday, leaders at an international conference held in London on the Libya crisis appointed gas-rich Qatar to host the first meeting of a follow-up Contact Group.

“This all confirms Qatar’s ambition to play a role as leader of the Arab world in the absence of the region’s traditional heavyweights such as Saudi Arabia and Egypt,” said London-based analyst Abdelwahad BadraKhan.

Qatari Foreign Minister Hamad bin Jassem Al-Thani said in the British capital that the conflict in Libya was an Arab affair in which regional states should become more involved.

Qatar’s high-profile role “shows the determination of its leaders to put their small country on the regional political map,” just like they are on the sporting calendar as host of the 2022 football World Cup, said BadraKhan.

“With a stable regime and reassured by a large US air base in Qatar”, the emir, Hamad bin Hamad Al-Thani, has been taking the initiative “in consultation with” Washington and Riyadh, according to BadraKhan.

And Egypt is only just emerging from the February revolution which toppled its longtime president Hosni Mubarak.

Eclipsed since independence by “big brother” Saudi Arabia, Qatar has turned into a player in its own right, with help from Doha-based news channel Al-Jazeera and its blanket coverage of the so-called “Arab spring” of revolts.

Doha has played the role of mediator in complex regional crises in Lebanon, Yemen and Sudan, with varying degrees of success.

Ibrahim Sharqieh, deputy head of Brookings Doha Center, said a new order was being put in place.

“Qatar has a role to play in all this with its financial muscle, a moderate political vision and opening, and expertise it has gained from being involved in resolving regional crises,” he said.

Sharqieh pointed out the country has good ties with the United States and arch-foe Iran, and has had political contacts as well as trading with Israel.

Mohamed Mesfer, a university lecturer in Doha, said the low profile kept by Syria and Algeria was also serving to boost Qatar, which apart from the United Arab Emirates has been the only Arab state untouched by unrest popping up across the region since January.

On the domestic front, Qatar has lined up legislative elections without being forced to bow to street protests.

Libyan rebels say the Gulf state has signed a contract to market oil from the rebel-held east of the country, and it to host and help launch a rebel television station.
