Mayor Bloomberg On Domestic Drones In NYC - Business Insider

New York City Mayor Michael Bloomberg considers the domestic use of military-style drones "scary" but says that there is no way to stop it.

?Everybody wants their privacy, but I don?t know how you?re going to maintain it,? Bloomberg said on his weekly radio show. ?It?s just we?re going into a different world, uncharted, and, like it or not, what people can do, what governments can do, is different ... you can?t keep the tides from coming in.?

In September a Congressional Research report stated that domestic drones may be able to bypass constitutional privacy safeguards because of their high level of sophistication.

At least 81 entities, including 17 police departments, have applied for permission to fly drones in U.S. airspace.

But the mayor seems to be referring to something more omnipresent, like having drones with ARGUS technology flying 17,500 feet above the Big Apple while transmitting high resolution images of people.

"There'll be cameras every place" within five years, Bloomberg estimated. "We're going to have more visibility and less privacy. I just don't see how you could stop that."

The mayor figures that if the city already has security cameras in strategic places around the city ? 2,400 in Manhattan alone as of 1998 ? then drones aren't any different.


?It's scary. What?s the difference whether the drones up in the air or in the building?? Bloomberg said. ?I mean intellectually, I have trouble making a distinction. And you know you're going to have face recognition software."

Donna Lieberman of the New York Civil Liberties Union told CBS that the mayor's nonchalance does nothing to quell legitimate concerns that the government could save the data to analyze it.

?It?s disappointing that the mayor shows such disdain for the legitimate concern of New Yorkers about their privacy," she said. "None of us expects that we?ll go unseen when we?re out on the street, but we also have the right to expect that the government isn?t making a permanent record."

Here the CBS news report with Bloomberg's remarks:

Reward linked to image is enough to activate brain's visual cortex

Friday, March 22, 2013

Once rhesus monkeys learn to associate a picture with a reward, the reward by itself becomes enough to alter the activity in the monkeys' visual cortex. This finding was made by neurophysiologists Wim Vanduffel and John Arsenault (KU Leuven and Harvard Medical School) and American colleagues using functional brain scans and was published recently in the leading journal Neuron.

Our visual perception is not determined solely by retinal activity. Other factors also influence the processing of visual signals in the brain. "Selective attention is one such factor," says Professor Wim Vanduffel. "The more attention you pay to a stimulus, the better your visual perception is and the more effective your visual cortex is at processing that stimulus. Another factor is the reward value of a stimulus: when a visual signal becomes associated with a reward, it affects our processing of that visual signal. In this study, we wanted to investigate how a reward influences activity in the visual cortex."

To do this, the researchers used a variant of Pavlov's well-known conditioning experiment: "Think of Pavlov giving a dog a treat after ringing a bell. The bell is the stimulus and the food is the reward. Eventually the dogs learned to associate the bell with the food and salivated at the sound of the bell alone. Essentially, Pavlov removed the reward but kept the stimulus. In this study, we removed the stimulus but kept the reward."

In the study, the rhesus monkeys first encountered images projected on a screen followed by a juice reward (classical conditioning). Later, the monkeys received juice rewards while viewing a blank screen. fMRI brain scans taken during this experiment showed that the visual cortex of the monkeys was activated by being rewarded in the absence of any image.

Importantly, these activations were not spread throughout the whole visual system but were instead confined to the specific brain regions responsible for processing the exact stimulus used earlier during conditioning. This result shows that information about rewards is being sent to the visual cortex to indicate which stimuli have been associated with rewards.

Equally surprising, these reward-only trials were found to strengthen the cue-reward associations. This is more or less the equivalent to giving Pavlov's dog an extra treat after a conditioning session and noticing the next day that he salivates twice as much as before. More generally, this result suggests that rewards can be associated with stimuli over longer time scales than previously thought.

Why does the visual cortex react selectively in the absence of a visual stimulus on the retina? One potential explanation is dopamine. "Dopamine is a signalling chemical (neurotransmitter) in nerve cells and plays an important role in processing rewards, motivation, and motor functions. Dopamine's role in reward signalling is the reason some Parkinson's patients fall into gambling addiction after taking dopamine-increasing drugs. Aware of dopamine's role in reward, we re-ran our experiments after giving the monkeys a small dose of a drug that blocks dopamine signalling. We found that the activations in the visual cortex were reduced by the dopamine blocker. What's likely happening here is that a reward signal is being sent to the visual cortex via dopamine," says Professor Vanduffel.

The study used fMRI (functional Magnetic Resonance Imaging) scans to visualise brain activity. fMRI scans map functional activity in the brain by detecting changes in blood flow. The oxygen content and the amount of blood in a given brain area vary according to the brain activity associated with a given task. In this way, task-specific activity can be tracked.

Senate gives pre-dawn OK to Democratic budget

(AP) ? An exhausted Senate gave pre-dawn approval Saturday to a Democratic $3.7 trillion budget for next year that embraces nearly $1 trillion in tax increases over the coming decade but shelters domestic programs targeted for cuts by House Republicans.

While their victory was by a razor-thin 50-49, the vote let Democrats tout their priorities. Yet it doesn't resolve the deep differences the two parties have over deficits and the size of government.

Joining all Republicans voting no were four Democrats who face re-election next year in potentially difficult races: Sens. Max Baucus of Montana, Mark Begich of Alaska, Kay Hagan of North Carolina and Mark Pryor of Arkansas. Sen. Frank Lautenberg, D-N.J., did not vote.

The vote came after lawmakers labored through the night on scores of symbolic amendments, ranging from voicing support for letting states collect taxes on Internet sales to expressing opposition to requiring photo ID's for voters.

The Senate's budget would shrink annual federal shortfalls over the next decade to nearly $400 billion, raise unspecified taxes by $975 billion and cull modest savings from domestic programs.

In contrast, a rival budget approved by the GOP-run House balances the budget within 10 years without boosting taxes.

That blueprint? by House Budget Committee Chairman Paul Ryan, R-Wis., his party's vice presidential candidate last year ? claims $4 trillion more in savings over the period than Senate Democrats by digging deeply into Medicaid, food stamps and other safety net programs for the needy. It would also transform the Medicare health care program for seniors into a voucher-like system for future recipients.

"We have presented very different visions for how our country should work and who it should work for," said Sen. Patty Murray, D-Wash., who chairs the Senate Budget Committee. "But I am hopeful that we can bridge this divide."

A day that stretched roughly 20 hours featured brittle debate at times. The loudest moment came toward the end, when senators rose as one to cheer a handful of Senate pages ? high school students ? who lawmakers said had worked in the chamber since the morning's opening gavel. Senators then left town for a two-week spring recess.

Congressional budgets are planning documents that leave actual changes in revenues and spending for later legislation, and this was the first the Democratic-run Senate has approved in four years. That lapse is testament to the political and mathematical contortions needed to write fiscal plans in an era of record-breaking deficits that until this year exceeded an eye-popping $1 trillion annually, and to the parties' profoundly conflicting views.

"I believe we're in denial about the financial condition of our country," Sen. Jeff Sessions of Alabama, top Republican on the Budget panel, said of Democratic efforts to boost spending on some programs. "Trust me, we've got to have some spending reductions."

Though budget shortfalls have shown signs of easing slightly and temporarily, there is no easy path for the two parties to find compromise ? which the first months of 2013 have amply illustrated.

Already this year, Congress has raised taxes on the rich after narrowly averting tax boosts on virtually everyone else, tolerated $85 billion in automatic spending cuts, temporarily sidestepped a federal default and prevented a potential government shutdown.

By sometime this summer, the government's borrowing limit will have to be extended again ? or a default will be at risk ? and it is unclear what Republicans may demand for providing needed votes. It is also uncertain how the two parties will resolve the differences between their two budgets, something many believe simply won't happen.

Both sides have expressed a desire to reduce federal deficits. But President Barack Obama is demanding a combination of tax increases and spending cuts to do so, while GOP leaders say they won't consider higher revenues but want serious reductions in Medicare and other benefit programs that have rocketed deficits skyward.

Obama plans to release his own 2014 budget next month, an unveiling that will be studied for whether it signals a willingness to engage Republicans in negotiations or play political hardball.

The amendments senators considered during their long day of debate were all non-binding, but some delivered potent political messages.

They voted in favor of giving states more powers to collect sales taxes on online purchases their citizens make from out-of-state Internet companies, and to endorse the proposed Keystone XL pipeline that is to pump oil from Canada to Texas refineries.

They also voted to voiced support for eliminating the $2,500 annual cap on flexible spending account contributions imposed by Obama's health care overhaul, and for charging regular postal rates for mailings by political parties, which currently qualify for the lower prices paid by non-profits.

In a rebuke to one of the Senate's most conservative members, they overwhelmingly rejected a proposal by Sen. Rand Paul, R-Ky., to cut even deeper than the House GOP budget and eliminate deficits in just five years.

The Democratic budget's $975 billion in new taxes would be matched by an equal amount of spending reductions coming chiefly from health programs, defense and reduced interest payments as deficits get smaller than previously anticipated.

This year's projected deficit of nearly $900 billion would fall to around $700 billion next year and bottom out near $400 billion in 2016 before trending upward again.

Shoehorned into the package is $100 billion for public works projects and other programs aimed at creating jobs.

Nevada depot blast: Was exercise that killed seven really necessary?

The training accident at Hawthorne Army Depot came during a live-fire exercise. These exercises carry risk, but military officials say they are needed to prepare troops for battle.

The deaths of seven US troops ? and the injuries of several others ? in a live-fire training exercises at a military base in Nevada Monday raises questions about just how necessary such training is for troops in an era of modern warfare.

'; } else if (google_ads.length > 1) { ad_unit += ''; } } document.getElementById("ad_unit").innerHTML += ad_unit; google_adnum += google_ads.length; return; } var google_adnum = 0; google_ad_client = "pub-6743622525202572"; google_ad_output = 'js'; google_max_num_ads = '1'; google_feedback = "on"; google_ad_type = "text"; google_adtest = "on"; google_image_size = '230x105'; google_skip = '0'; // -->

Though the cause of the fatalities, which happened Hawthorne Army Depot at 10 p.m. local time, is still under investigation, it appears that a 60-millimeter mortar shell exploded as Marines were preparing to fire the shell.

Would they get the same experience using blank rounds that still simulated the noise and confusion of battle, for example? Senior US military officials say the answer to that question is "no." Though such exercises entail some measure of risk, they are vital, the officials suggest.?

Some argue that the danger inherent in live-fire exercises is key to instilling a sense of fear, so that troops can come to envision in some small measure what battle will be like. Others contend that using live rounds during training hones troops by making them more focused during drills.

In the end, the point of training is to do everything possible to make the men and women of the military prepared to go to war, and live-fire exercises are seen as being a crucial part of that process.

?We don?t want war to be the first time a soldier has handled ? and is comfortable ? with live rounds,? says Lt. Col. Jerome Pionk, the Army?s team chief for weapons, environment, and technology.

?It?s not so much the sense of danger but the awareness of responsibility that is heightened during live-fire exercises,? adds Colonel Pionk.

This experience breeds confidence, Pionk says. He recalls his first live-fire training exercise in the Army: ?I didn?t come from a hunting culture,? he says.

?When you get out there with blanks, you know it?s not real. When you have that live ammo, though, there?s a sense of heightened responsibility,? he says. ?You get absorbed in that. You think, ?I?ve got live bullets here. I?ve got to take this seriously.? ?

What?s more, there are often physical differences in weight between live munitions and training rounds, military officials add.

To avoid accidents, there are a number of safety measures that precede live-fire exercises, Pionk says. ?When I was an infantry platoon leader, you did a dozen rehearsals before you were issued live ammo? for an exercise.

Such rehearsals without live rounds are standard even if a unit is returning from Afghanistan or ?if you have nothing but senior guys ? extremely well-trained guys ? before they get locked-and-loaded with live ammo,? he adds. ?

The number of live-fire exercises troops take part in vary with their military occupational specialties, but troops are generally required to do live-fire exercises at least once a year as part of their annual qualification requirements.

Hawthorne Army Depot, a base that is nearly 230 miles square and serves as an ammunition depot, is an ideal spot for live-fire exercises.

According to the depot?s website, the remote base in the heart of Nevada's mountainous desert offers a ?realistic simulation of the situation in Afghanistan? for troops, including Special Operations Forces, who train there. This training includes live-fire exercises, often for troops preparing to deploy to war.

Even beyond live fire-training, military exercises generally involve risks, particularly as troops are preparing for ongoing wars.?

Seven US troops died in February 2012 during a midair collision of two helicopters at Marine Corps Air Station Yuma, which sits along the jagged, rocky mountains and open desert of the Arizona-California border and is also meant to simulate the conditions in Afghanistan.

There were five such crashes in 2009, and another five in 2010.?

A Marine spokesman says the fatal incident at Hawthorne is under investigation.

Malls must move beyond shopping to survive in Internet era

By Tom Bill

CANNES, France (Reuters) - As growing numbers of shoppers move online, European mall owners are looking to pull in customers by including services that can't be replicated on the Web like hospital care and government offices.

Malls must become more like full-service community centers to survive in the face of a growing list of failed retailers like HMV and Blockbuster, property experts at the annual MIPIM trade fair in Cannes, France, told Reuters.

On the flip side of that retail revolution, the experts see big gains in warehousing as more goods are sent and returned via post.

"The days of the stand-alone mall are numbered," said David Roberts, the chief executive of architect Aedas, one of the five largest practices in the world. The company has been involved in city masterplan projects in Asia, Europe and the Middle East.

"In 20 years time you will find stores that sell books and DVDs replaced by sites that give people a reason to go the mall ... art galleries, education centers and health and spa treatments."

Florencio Beccar, fund manager of CBRE Global Investors European shopping centre fund, cited the recent purchase of a mall in Germany, saying the fact it included a large medical centre was "a big plus".

"I once saw a clinic in a Brazilian mall where you checked in and are buzzed on a device when they are ready. In the meantime you go shopping," he said. "With the ageing population in Europe you can see that happening more and more."

CBRE Investors, which has about 14 billion euros ($18.2 billion) of retail property under management in Europe and 5,000 tenants, also owns a mall in southern Sweden with a library and a local municipal office, he said.

"More shopping centre developers will have early talks with these sorts of tenants as well as the big anchor retailers," Beccar said.

Mall owners like Land Securities, Intu, Westfield and Klepierre have increased the number of restaurants and cinemas to persuade shoppers to stay longer, and offer promotions to reward frequent shoppers who can be tracked via their mobile phones.

COMMUNITY CENTRES, ADVENTURE PARKS

But these steps don't go far enough, some experts say, in light of a forecast last month that 90 percent of retail sales growth in Britain, France and Germany between 2012 and 2016, or 91.5 billion euros, is expected to be online, according to the property arm of French insurer AXA, which manages 43 billion euros of assets.

As well as changing what's inside, mall owners will need to borrow ideas from developing markets like Dubai and China where centers are part of wider mixed-use developments where people live or include open spaces where they spend leisure time, Roberts said.

"Convenience and Internet shopping has created a breakdown in community structures and there's a gap there waiting to be filled," he said.

"There is a complete lack of vision among many shopping centre owners," said Joe Valente, a managing director at JP Morgan Asset Management, who helps manage 7 billion euros of real estate in Europe.

"The big thing that's missing is that unlike almost every other industry they haven't caught on to building their own brand. Why not have a bluewater.com?" he said, referring to the large mall of the same name in southeast England.

"Landlords fear cannibalizing sales but in 10 to 15 years they won't have a choice because they will be cannibalized anyway," he said. In other words, a growing number of shoppers will move online whatever malls do.

"On a mall website you could book a parking space, a restaurant table or your car to be valeted. Why do people go to Covent Garden?" he asked of the central London district.

"There's nothing there you won't find anywhere else but I would argue it's a strong brand."

Christian Ulbrich, chief executive for Europe, Middle East and Africa at property consultant Jones Lang LaSalle, said: "Stores will get bigger and become more like adventure parks that attack all of your emotions.

"For example, Globetrotter has a climbing wall and cycle track in its Frankfurt store to try out its products," he said of the German outdoor clothing and equipment retailer.

WAREHOUSING

While retailers and mall owners struggle to find answers, all agree that warehouse property owners are the big beneficiaries of the change in retail habits.

Every additional 1 billion euros of online sales resulted in an average additional warehouse demand of approximately 72,000 square meters in Britain, Germany and France over the last five years, a report from warehouse landlord Prologis said last year.

"Logistics is the new retail," said Simon Hope, global head of capital markets at property consultant Savills, referring to the way changing consumer trends will affect the way investors see property.

"There is a trend of money moving away from all but the best and most regionally dominant malls into logistics as they are economically shielded," he said.

The fact that the Norwegian and Chinese sovereign wealth funds have recently invested in the sector, as well as a report that Brookfield, lower Manhattan's largest office landlord, is trying to do the same, shows serious bets are being made on logistics property, Hope said.

Yields for high quality logistics property can be six or seven percent versus four or five percent for top shopping centers.

As another example of how retailers may re-think their operations, some are likely to club together to operate out of smaller logistics sites close to city centers to enable same-day deliveries, a service increasingly in demand, Ulbrich said.

"The issue they all face is that shopping is no longer enough of a reason to go to shopping centers."
