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.
“Here is what I would like for you to know: In America, it is traditional to destroy the black body—it is heritage.”
Last Sunday the host of a popular news show asked me what it meant to lose my body. The host was broadcasting from Washington, D.C., and I was seated in a remote studio on the Far West Side of Manhattan. A satellite closed the miles between us, but no machinery could close the gap between her world and the world for which I had been summoned to speak. When the host asked me about my body, her face faded from the screen, and was replaced by a scroll of words, written by me earlier that week.
The host read these words for the audience, and when she finished she turned to the subject of my body, although she did not mention it specifically. But by now I am accustomed to intelligent people asking about the condition of my body without realizing the nature of their request. Specifically, the host wished to know why I felt that white America’s progress, or rather the progress of those Americans who believe that they are white, was built on looting and violence. Hearing this, I felt an old and indistinct sadness well up in me. The answer to this question is the record of the believers themselves. The answer is American history.
As the Vermont senator gains momentum, Claire McCaskill rushes to the frontrunner’s defense.
Obscured by the recent avalanche of momentous news is this intriguing development from the campaign trail: The Hillary Clinton campaign now considers Bernie Sanders threatening enough to attack. Fresh off news that Sanders is now virtually tied with Hillary in New Hampshire, Claire McCaskill went on Morning Joe on June 25 to declare that “the media is giving Bernie a pass … they’re not giving the same scrutiny to Bernie that they’re certainly giving to Hillary.”
The irony here is thick. In 2006, McCaskill said on Meet the Press that while Bill Clinton was a great president, “I don’t want my daughter near him.” Upon hearing the news, according to John Heilemann and Mark Halperin’s book Game Change, Hillary exclaimed, “Fuck her,” and cancelled a fundraiser for the Missouri senator. McCaskill later apologized to Bill Clinton, and was wooed intensely by Hillary during the 2008 primaries. But she infuriated the Clintons again by endorsing Barack Obama. In their book HRC, Aimee Parnes and Jonathan Allen write that, “‘Hate’ is too weak a word to describe the feelings that Hillary’s core loyalists still have for McCaskill.”
In the United States, when an unmarried man has a baby, his partner can give it up without his consent—unless he happens to know about an obscure system called the responsible father registry.
Christopher Emanuel first met his girlfriend in the fall of 2012, when they were both driving forklifts at a warehouse in Trenton, South Carolina. She was one of a handful of women on the job; she was white and he was black. She ignored him at first, and Emanuel saw it as a challenge. It took multiple attempts to get her phone number. He says he “wasn’t lonely, but everybody wants somebody. Nothing wrong with being friends.”
Emanuel, who is now 25, describes himself as a non-discriminatory flirt. He was popular in high school and a state track champion. According to the Aiken High School 2008 yearbook, he was voted “Most Attractive” and “Best Dressed.” Even his former English teacher Francesca Pataro describes him as a “ray of sunshine.” Emanuel says he’s “talked”—euphemistically speaking—with a lot of women: “Black, Puerto Rican, Egyptian, and Vietnamese.” But before he met this girlfriend, he says, he had never seriously dated a white girl.
In 1992, the neuroscientist Richard Davidson got a challenge from the Dalai Lama. By that point, he’d spent his career asking why people respond to, in his words, “life’s slings and arrows” in different ways. Why are some people more resilient than others in the face of tragedy? And is resilience something you can gain through practice?
The Dalai Lama had a different question for Davidson when he visited the Tibetan Buddhist spiritual leader at his residence in Dharamsala, India. “He said: ‘You’ve been using the tools of modern neuroscience to study depression, and anxiety, and fear. Why can’t you use those same tools to study kindness and compassion?’ … I did not have a very good answer. I said it was hard.”
New data shows that students whose parents make less money pursue more “useful” subjects, such as math or physics.
In 1780, John Adams wrote a letter to his wife, Abigail, in which he laid out his plans for what his children and grandchildren would devote their lives to. Having himself taken the time to master “Politicks and War,” two revolutionary necessities, Adams hoped his children would go into disciplines that promoted nation-building, such as “mathematicks,” “navigation,” and “commerce.” His plan was that in turn, those practical subjects would give his children’s children room “to study painting, poetry, musick, architecture, statuary, tapestry, and porcelaine.”
Two-hundred and thirty-five years later, this progression—“from warriors to dilettantes,” in the words of the literary scholar Geoffrey Galt Harpham—plays out much as Adams hoped it would: Once financial concerns have been covered by their parents, children have more latitude to study less pragmatic things in school. Kim Weeden, a sociologist at Cornell, looked at National Center for Education Statistics data for me after I asked her about this phenomenon, and her analysis revealed that, yes, the amount of money a college student’s parents make does correlate with what that person studies. Kids from lower-income families tend toward “useful” majors, such as computer science, math, and physics. Those whose parents make more money flock to history, English, and performing arts.
The Islamic State is no mere collection of psychopaths. It is a religious group with carefully considered beliefs, among them that it is a key agent of the coming apocalypse. Here’s what that means for its strategy—and for how to stop it.
What is the Islamic State?
Where did it come from, and what are its intentions? The simplicity of these questions can be deceiving, and few Western leaders seem to know the answers. In December, The New York Times published confidential comments by Major General Michael K. Nagata, the Special Operations commander for the United States in the Middle East, admitting that he had hardly begun figuring out the Islamic State’s appeal. “We have not defeated the idea,” he said. “We do not even understand the idea.” In the past year, President Obama has referred to the Islamic State, variously, as “not Islamic” and as al-Qaeda’s “jayvee team,” statements that reflected confusion about the group, and may have contributed to significant strategic errors.
Most adults can’t remember much of what happened to them before age 3 or so. What happens to the memories formed in those earliest years?
My first memory is of the day my brother was born: November 14, 1991. I can remember my father driving my grandparents and me over to the hospital in Highland Park, Illinois, that night to see my newborn brother. I can remember being taken to my mother’s hospital room, and going to gaze upon my only sibling in his bedside cot. But mostly, I remember what was on the television. It was the final two minutes of a Thomas the Tank Engine episode. I can even remember the precise story: “Percy Takes the Plunge,” which feels appropriate, given that I too was about to recklessly throw myself into the adventure of being a big brother.
In sentimental moments, I’m tempted to say my brother’s birth is my first memory because it was the first thing in my life worth remembering. There could be a sliver of truth to that: Research into the formation and retention of our earliest memories suggests that people’s memories often begin with significant personal events, and the birth of a sibling is a textbook example. But it was also good timing. Most people’s first memories date to when they were about 3.5 years old, and that was my age, almost to the day, when my brother was born.
The singer’s violent revenge fantasy was intended to provoke outrage, and to get people to talk about her. It succeeds on both counts.
Of all the scandalized reactions to Rihanna’s music video for “Bitch Better Have My Money,” my favorite comes, as is not surprising for this sort of thing, from the Daily Mail. Labelling herself in the headline as a “concerned parent” (a term to transport one to the days of Tipper Gore’s crusade against lyrics if there ever was one), Sarah Vine opens her column by talking at length about how so very, very reluctant she was to watch Rihanna’s new clip. Then she basically goes frame-by-frame through the video, recounting her horror at what unfolds. “By the time it had finished, I wondered whether I ought not to report [Rihanna] to the police,” Vine writes. “Charges: pornography, incitement to violence, racial hatred.”
The outcome of Sunday's referendum was as much a rejection of an ongoing policy as it was disapproval of the Eurogroup's bailout proposals.
Greece is now in uncharted territory. The final tally of Sunday’s referendum had 61 percent of Greeks voting“no” and 39 percent “yes” on whether or not to approve the current bailout plan from Eurogroup leaders. The outcome was a victory for Prime Minister Alexis Tsipras, who had strongly urged citizens to reject the deal—but now Greece must return to the negotiating table to discuss a new plan with its creditors.
On Monday, Greece’s finance minister Yanis Varoufakis quit, believing that negotiations might proceed more smoothly if he was absent. He will be succeeded by Euclid Tsakalotos, Greece’s deputy foreign minister who also served as the coordinator of the negotiations between Athens and its creditors. Varoufakis posted a statement on his blog that makes clear what Greece is looking for from its creditors: “It is, therefore, essential that the great capital bestowed upon our government by the splendid NO vote be invested immediately into a YES to a proper resolution—to an agreement that involves debt restructuring, less austerity, redistribution in favor of the needy, and real reforms.”
