That's the argument made by computer scientists M.P.Sivaram Kumar and S. Rajasekaran in a recent article in the Journal of Computing entitled "Path Planning Algorithm for Extinguishing
Forest Fires." Their thesis is simple: the vast majority of forests are destroyed by wild forest fires, and current methods of sylvan vigilance -- mainly those involved individual personnel on foot patrol -- are grossly inefficient in identifying emerging threats. Their pre-defined route may be damaged or obscured, inclement weather affects visibility, and life on patrol is boring and "miserable," leading to a lack of attention.
Kumar and Rajasekaran argue that deploying robotic systems throughout wooded areas will increase firefighters' ability not just to identify emerging threats, but also to more effectively plot the path of a wildfire, and then deploy the appropriate resources to the right places. The two imagine a grid-based system of automated drones, designed to detect abnormal changes in temperature and relay data back to a command center:
The automatic forest fire detection and extinguishing system consists of
nodes deployed deterministically in a forest area and all
the nodes know their location based on coordinate values
of a matrix. Each node is equipped with a temperature
sensor and an Omni directional antenna. Nodes continuously monitor the environment to check if there is fire or
not in the particular cell. When change in temperature i.e.
temperature raises above a certain threshold, is detected
by a particular node they send message packets which
contain location measurements. These packets are received by one of the corner node. The corner node then
sends the packet to the Actor which in turn will process
the packet which can be used in reaching the target area
to extinguish fire.
On-the-ground nodes, they argue, are significantly better than the preexisting satellite detection systems that, due to a long scan period and low resolution of images, end up detecting fires relatively late. Relying on satellites often means that firefighting personnel deploy more resources in their firefighting than would otherwise be necessary.
There are obvious environmental concerns to stringing a sprawling forest with robotic nodes. Introducing any man-made object, even stationary a drone, can have unintended consequences on a complex arboreal ecosystem. Unexpected costs -- a tree falling in the woods, surprise visits from assorted large mammals -- could make deploying and maintaining a robotic grids prohibitively expensive.
But among the significant additional benefits: potentially saving lives. Wireless Emergency Alerts (WEA), a system developed by FEMA, the FCC, and wireless carriers, will soon be deployed in emergency situations like severe weather to notify citizens of imminent threats to their safety. Within the next few weeks, nearly everyone in the country with a mobile phone could start receiving text messages from the National Weather Service, local law enforcement, or perhaps even the President. Here's how it works:
In the event of an emergency, an authorized alerting agency can select a cell tower (or towers) to broadcast a WEA. In order to receive the message, a person must be within range of the cell-tower broadcast, and must have a phone capable of "hearing" the the broadcast. Most cellular devices manufactured after mid-2011 already have this capability.
It is through the use of CB technology that CMAS is able to provide some geographic targeting without the need for opting-in. However, it is important to note that because WEAs are "broadcast" from towers, the geo-targeting feature is not as precise as GPS. GPS is a two-way street of communication between a GPS-equipped device and various positioning satellites. WEAs are not two-way...it is simply a modern day "shout" to give a heads-up that something requires your attention.
According to the National Fire Protection Association, only 11 people were killed in wildfire-related incidents in 2011. But application of the sensor technology to, say, rivers with a high likelihood of flooding, earthquake-prone regions, and other unstable natural centers could give first responders a useful heads-up. When tied in with FEMA's new WEA system, average citizens could have enough advance warning of danger to protect themselves in the event of a natural disaster. And in the event of a fast-moving fire or flood, a few extra minutes could mean the difference between life and death.
The agreement doesn’t guarantee that Tehran will never produce nuclear weapons—because no agreement could do so.
A week ago I volunteered my way into an Atlantic debate on the merits of the Iran nuclear agreement. The long version of the post is here; the summary is that the administration has both specific facts and longer-term historic patterns on its side in recommending the deal.
On the factual front, I argued that opponents had not then (and have not now) met President Obama’s challenge to propose a better real-world alternative to the negotiated terms. Better means one that would make it less attractive for Iran to pursue a bomb, over a longer period of time. Real world means not the standard “Obama should have been tougher” carping but a specific demand that the other countries on “our” side, notably including Russia and China, would have joined in insisting on, and that the Iranians would have accepted.
Orr: “Sometimes a thing happens. Splits your life. There’s a before and after. I got like five of them at this point.”
This was Frank offering a pep talk to the son of his murdered former henchman Stan in tonight’s episode. (More on this in a moment.) But it’s also a line that captures this season of True Detective so perfectly that it almost seems like a form of subliminal self-critique.
Remember when Ray got shot in episode two and appeared to be dead but came back with a renewed sense of purpose and stopped drinking. No? That’s okay. Neither does the show: It was essentially forgotten after the subsequent episode. Remember when half a dozen (or more) Vinci cops were killed in a bloody shootout along with dozen(s?) of civilians? No? Fine: True Detective’s left that behind, too. Unless I missed it, there was not a single mention of this nationally historic bloodbath tonight.
The former secretary of defense lobbied for the repeal of “Don’t ask, don’t tell,” and has now ended the Boy Scouts’ ban on gay scoutmasters.
Eagle Scout. Young Republican. CIA recruit. Air Force officer. CIA director. Secretary of defense.
It’s not the resume of a radical civil-rights campaigner, but Robert Gates has now integrated two of the great bastions of macho American traditional morality—first the U.S. armed forces, and now the Boy Scouts of America. In both cases, Gates pursued a careful, gradual strategy, one that wasn't fast enough for activists. In both cases, he was careful to take the temperature of constituents. And in both cases, once he was ready to act, he did so decisively. In the end what seemed to matter most was not Gates’s personal feelings but his determination to safeguard institutions he cared about and his deft skills as a bureaucratic operator.
Has the Obama administration’s pursuit of new beginnings blinded it to enduring enmities?
“The president said many times he’s willing to step out of the rut of history.” In this way Ben Rhodes of the White House, who over the years has broken new ground in the grandiosity of presidential apologetics, described the courage of Barack Obama in concluding the Joint Comprehensive Plan of Action with the Islamic Republic of Iran, otherwise known as the Iran deal. Once again Rhodes has, perhaps inadvertently, exposed the president’s premises more clearly than the president likes to do. The rut of history: It is a phrase worth pondering. It expresses a deep scorn for the past, a zeal for newness and rupture, an arrogance about old struggles and old accomplishments, a hastiness with inherited precedents and circumstances, a superstition about the magical powers of the present. It expresses also a generational view of history, which, like the view of history in terms of decades and centuries, is one of the shallowest views of all.
Companies that overvalue alpha-male behavior need to change—both to retain female talent and for the bottom line.
When it comes to gender equality in the workplace, the research on its economic benefits is clear: Equality can boost profits and enhance reputation. And then there’s also the fact that it’s more fair. But the progress of women in the workplace is so far inadequate: Women are woefully underrepresented in executive positions, the pay gap persists, and the motherhood penalty is very real.
Barbara Annis is the founder of the Gender Intelligence Group, a consultancy that works with executives at major firms (including Deloitte, American Express, BMO Financial Group, and eBay) to create strategies to transform their work cultures into ones that are friendly to both men and women.
I recently spoke with Annis about her work and the challenges to achieving gender parity. The following transcript of our conversation has been edited for clarity.

Several years ago, Ta-Nehisi Coates took his son, not yet 5, to see a movie on the Upper West Side of Manhattan. As his son made his way off the escalator, a white woman pushed him and said, “Come on!” Chaos ensued. There was a black parent’s rage and a white man’s threat to have the black parent arrested. Coates narrates the incident in cool, steady prose. Ultimately, he writes of the regret he carries: “In seeking to defend you I was, in fact, endangering you.”
Connecticut, Missouri, and Georgia have dropped the slave-owning presidents from their annual fund-raising dinners, and many more states could follow suit.
The Democratic Party is on the hunt for a new pair of fathers.
Last week, Democrats in Connecticut rather matter-of-factly decided to oust Thomas Jefferson and Andrew Jackson from their place of honor as the namesakes of the state party’s annual fund-raising dinner. The debate—such as it was—over the legacies of the two slave-owning presidents took all of two minutes, a spokesman for the state central committee said, and the vote to strip their names from the dinner was unanimous. A week earlier, Missouri changed the name of its Jefferson-Jackson dinner to honor native son Harry Truman instead, and two days after Connecticut’s vote, Georgia Democrats announced a similar change with even less fanfare.
Educators seldom have enough time to do their business. What’s that doing to the state of learning?
It’s common knowledge that teachers today are stressed, that they feel underappreciated and disrespected, and disillusioned. It’s no wonder they’re ditching the classroom at such high rates—to the point where states from Indiana to Arizona to Kansas are dealing with teacher shortages. Meanwhile, the number of American students who go into teaching is steadily dropping.
A recent survey conducted jointly by the American Federation of Teachers and Badass Teachers Association asked educators about the quality of their worklife, and it got some pretty harrowing feedback. Just 15 percent of the 30,000 respondents, for example, strongly agreed that they’re enthusiastic about the profession. Compare that to the roughly 90 percent percent who strongly agreed that they were enthusiastic about it when they started their career, and it’s clear that something has changed about schools that’s pushing them away. Roughly three in four respondents said they “often” feel stressed by their jobs.
A controversial treatment shows promise, especially for victims of trauma.
It’s straight out of a cartoon about hypnosis: A black-cloaked charlatan swings a pendulum in front of a patient, who dutifully watches and ping-pongs his eyes in turn. (This might be chased with the intonation, “You are getting sleeeeeepy...”)
Unlike most stereotypical images of mind alteration—“Psychiatric help, 5 cents” anyone?—this one is real. An obscure type of therapy known as EMDR, or Eye Movement Desensitization and Reprocessing, is gaining ground as a potential treatment for people who have experienced severe forms of trauma.
Here’s the idea: The person is told to focus on the troubling image or negative thought while simultaneously moving his or her eyes back and forth. To prompt this, the therapist might move his fingers from side to side, or he might use a tapping or waving of a wand. The patient is told to let her mind go blank and notice whatever sensations might come to mind. These steps are repeated throughout the session.
