Sprawl disturbs cicada cycles

Posted on by

Clearing land for suburban development disrupts cicada cycles:

“They have a tight connection with the tree,” says Dan Babbitt, the manager of the insect zoo at the Smithsonian’s National Museum of Natural History. Cicadas spend their underground years feeding off the roots of trees. Then when they’re ready to come up, they crawl back out along the tree trunk to the branches where they lay their eggs, all in the hopes that the next generation of cicadas will fall back into the soil, burrow down to the roots, and feed there for another 17 years.

This is why leafy residential neighborhoods often have some of the best cicada sightings (and sounds). It’s also why the absolute worst thing we could do to the creatures is clear-cut whole stretches of once-rural land for new development while they’re down there. Get rid of the trees, and you get rid of the cicadas. And re-planting those sad saplings common along many freshly paved roads in the exurbs won’t help…

“When they go out and build these things around Champaign-Urbana, they cut the trees down, they bring in the bulldozers, they pull up the top soil, and they stick the houses down,” Cooley says. “None of the cicadas in the ground there would have survived that. None of anything in the ground would have survived that.”

Some periodical cicadas do well in older, tree-lined suburbs, Cooley says, those places where houses were built slowly over time, “where they didn’t take the big trees.” Across history, it’s hard to tell if the shape and geography of broods has altered significantly around the footprint of expanding cities. Early records on when and where they appeared – and which broods were which – aren’t all that reliable. Some “straggler” cicadas also appear off the cycle of the rest of a brood, further confusing history’s witnesses.

Just another way that suburban development disrupts natural habitats. But, I’m still left with two pressing questions:

1. Would the average suburbanite see this as a problem? For those who live in the areas with more cicadas, are they viewed as a big nuisance even if they are only around every 17 years?

2. There is no indication in this article about how destructive this is. How bad is it if suburban development wipes out cicadas? What are the side effects? This is related to Question 1: perhaps suburbanites would be friendly toward cicadas if they knew they were making their lives and the habitat better.

A “brain gain” in rural America?

Posted on by

A rural sociologist argues that rural America is experiencing a “brain gain” of young adults:

Hjartarson is among what University of Minnesota Rural Sociologist Ben Winchester coins the “Brain Gain,” in rural America.

“Discussions about the future of rural communities can have a negative tone, but this isn’t your grandfather’s rural,” Winchester said. “You look at the numbers and you can see the rural narrative is being rewritten.”…

However, the actual number of people living in rural areas in the United States increased between 1970 and 2010 from 53.5 million to 59.5 million. Urban areas grew, too, but at a rate faster than rural areas, resulting in a proportional decline of the population living rural.

“When it comes to 30- to 40-year-olds, one in five live in a rural area today,” Winchester said. “There is a growth in rural areas among the 30- to 35-year-old cohort, an age when a lot of people are re-examining their lives and looking for low density living. That’s also the cohort we are seeing decreasing in numbers in many metro areas.”…

“When it comes to the reasons 30- to 40-year-olds say they want to move to a rural area, jobs isn’t even in the top 10,” Winchester said. “Quality of life is No. 1. Others are a slower pace, lower cost of housing, and safety and security. Many of these people are creating their own jobs.”

Sounds interesting but we would have to see more data to tease this out. If the rural population increased 6 million between 1970 and 2010, how much of this was due to birth rates in these areas versus new residents moving in? How does the rural population growth rate compare to that of cities and suburbs? That to me is the real comparison: how do rural areas stack up against the dominant place of living for Americans: the suburbs.

Also, it sounds like this could be a class issue based on the quality of life issues pushing people toward rural areas. Who exactly are the 30-40-year-olds moving to rural areas? Would it be safe to guess that they are generally well educated and have the abilities and training for creating their own jobs?

Micro-apartments in Seattle

Posted on by

Here is an overview of the growth in micro-apartments in Seattle:

Seattle Mayor Mike McGinn is on record in support of micro apartments, as is City Council member Richard Conlin.

“The private market is building affordable housing for people who want it,” Conlin said. “Fundamentally, this is a good thing.”

Young people starting out, service workers and retirees on limited incomes all need affordable housing, Conlin and other supporters said.

Forty-one micro housing projects have come through the Seattle Department of Planning and Development since 2006, spokeswoman Cyndi Wilder said. Of those, 28 received permits and 13 are under examination.

The planning department is aware of the debate over the review process for micro apartment buildings, she said, and the Seattle City Council “is going through an information-gathering process.”

It would be interesting to hear more about why Seattle and a few other cities are approving more micro-apartments while not as much is happening in other cities. This isn’t necessarily happening in the densest urban areas so is this more about regulation or the willingness to try new housing arrangements (perhaps in cities that are more “bohemian”)?

This article also presents an angle that I haven’t seen much thus far in news coverage: nearby residents who oppose large numbers of micro-apartments. I wonder if micro-apartments are encountering typical NIMBY concerns such as traffic and changes to the neighborhood or whether opposition is focused on unique attributes of the units like higher density and the type of people who might live in such units.

Arguing over whether spires and antennas at top of skyscrapers count for a building’s height

Posted on by

There is an ongoing argument, including this opinion piece from a “Chicago partisan,” about what at the top of a skyscraper should count toward the building’s official height. The latest round of argument involves the new World Trade Center building:

So far, nothing is official: the Council on Tall Buildings and Urban Habitat, the international organization of skyscraper engineers, designers and builders that certifies a building’s height, will weigh in only when One World Trade Center is completed. At an expected, historically symbolic 1,776 feet, the New York tower seems to have a solid claim.

But Chicagoans who live in the shadow of the 1,451-foot tall Willis Tower, which has held the title of nation’s tallest for some 40 years, should cry foul — because deciding just how tall a building is turns out to be more complicated than it might seem…

The council has three categories for measuring the heights of tall buildings: height to “architectural top,” “highest occupied floor” and “height to tip.” This may seem like splitting hairs, but the differences can be considerable.

The meanings of “height to tip” and “highest occupied floor” are self-evident. But “architectural top,” the category the council uses to officially crown the tallest building, is less clear; it includes “spires,” but not “antennas, signage, flag poles or other functional-technical equipment.” This wording deliberately makes the short, pointy tops of the Petronas Towers count, but leaves out the much taller antennas that crown the Willis Tower.

The way this argument is going, it seems like city partisans want to change the definition of building heights in a way that best advantages their tallest structure. Why? This is more about status and prestige than anything else. The city with the official tallest building can claim something about themselves. Certain cities, like Chicago and New York, are known for their skylines and have historically dominated this international race.

I’m not sure why exactly this matters for certain cities. On the one hand, these tallest buildings can dominate a skyline. Being at the top of the record books can bring some attention, though it is unclear what exactly it leads to. On the other hand, the square footage of residential or commercial space that one building can add doesn’t make or break a business district (unless, perhaps, it is the only really tall building). Also, the tallest building can be built nearly anywhere, whether in New York, Chicago, Kuala Lumpur, or Dubai. Does the tallest building really signal architectural or engineering competence? Doesn’t it tell us something that not every major or global city is chasing this record?

In other words, this might be a record that only a few cities and boosters really care about.

Chicago suburb to raise revenue by selling guns

Posted on by

St. Charles, Illinois has one solution for communities looking to raise revenues: sell confiscated and used guns back to the public.

But while some Chicago-area communities host buybacks where weapons are turned in and destroyed, one suburban police department is poised to sell about 20 firearms to two licensed dealers, including some guns seized from criminals.

“There’s value in these guns,” said police Chief James Lamkin of west suburban St. Charles. “They’re not illegal guns. Quite honestly, it’s a bottom line for us.”

Though Arizona has just enacted a controversial state law requiring local departments to sell firearms that are surrendered or go unclaimed, the practice appears to be unusual in the Chicago area. The Chicago Police Department and several suburban law-enforcement agencies, as well as Illinois State Police, say they destroy weapons after they’re turned in or no longer needed as evidence…

The choice for a public agency to sell or destroy seized weapons underscores the push in many suburbs to find new ways to generate revenue without raising taxes. The issue also places St. Charles in an unusual position among law enforcement agencies at a time when the gun control debate has been re-energized by the Sandy Hook school shooting and, in Illinois, by the current effort to enact a concealed carry law before a court-imposed June deadline.

My guess is that the negative publicity from a story like this – having a fairly well-off suburb make the front page of the Chicago Tribune for selling guns – outweighs the revenue that may come from selling 20 guns. This is the sort of negative attention that suburbs try to avoid. Yet, this is what happens when many American communities are desperate to find revenues. It would be interesting to see what St. Charles residents think of this. Does this story that could make their community look bad overpower the efforts the local government is making to avoid raising taxes?

McMansion owning Vermont governor criticized for real estate dealing with neighbor

Posted on by

The governor of Vermont has run into some real estate trouble after buying the property of a neighbor:

Soon after the successful real estate investor built his McMansion on a rural dirt road here outside Vermont’s capital, he began throwing his wealth around, striking a deal to bail out his neighbor from a looming tax sale by buying the man’s property for a quarter of its appraised value.

Such a sale is not uncommon and likely would have gone unnoticed. Except the buyer was the governor of Vermont, Peter Shumlin. And the seller, Jerry Dodge, was a hard-luck ne’er-do-well with a criminal record and what his friends and family describe as limited intellect and diminishing prospects.

Since word of the deal surfaced last week, Shumlin has been under intense scrutiny in the state. Real estate lawyers generally conclude that he did nothing illegal, but that the governor might still have held himself to a higher standard of conduct, raising the question of when a savvy business deal becomes bad for his politics…

Some of Dodge’s dissatisfaction appears to have been fueled by family and friends telling him he took too little for his property. He recalled reciting the Pledge of Allegiance as a child, before he left school in the ninth grade. It’s not justice for all, he said. It’s “justice for the rich.”

Sounds like a sticky situation for a politician who doesn’t want to be seen taking advantage of another resident. At the same time, the use of the term McMansion is intriguing. See a picture of Shumlin’s house here and a wider overhead view here. From these far-off pictures, it doesn’t look too much like a McMansion. The house might have a large square footage but the exterior appears understated and the house does not dominate the large lot. In using the term McMansion, the AP might be referring more to the home’s recent construction by a wealthy resident rather than the architecture and design of a home within a suburban subdivision. The rest of the story does seem to play up the angle that Shulmin’s house is a wealthy and luxurious one, particularly compared with the more run-down property of his neighbor.

Chicago tries out a “pedestrian scramble” intersection

Posted on by

Chicago has started testing the “pedestrian scramble” at a Loop intersection:

The changes center on a new pedestrian crossing pattern – dubbed the “pedestrian scramble” – that will be introduced at the intersection of State Street and Jackson Boulevard…

The test involves stopping all vehicles – heading east on Jackson and north and south on State – for about 14 seconds every other light cycle to give pedestrians a jump on traffic to cross in all directions, including diagonally, according to Bill McCaffrey, a spokesman for the Chicago Department of Transportation.

Developed more than 70 years ago, the pedestrian scramble allows pedestrians a running start to cross six ways instead of four ways.

The experiment is part of a larger plan by Chicago Transportation Commissioner Gabe Klein to reduce speeds and the number of vehicle travel lanes on busy streets in an effort to slash the number of crashes…

Klein’s strategy involves narrowing some streets, or putting them on a “road diet.’’

Two quick thoughts:

1. This reminds me of photographs of busy intersections in Tokyo where you see mobs of people crossing at all angles. See short videos here and here. Indeed, other countries have used pedestrian scrambles for decades.

2. People may not like the idea of a “road diet” but there is evidence that reducing traffic capacity could be more effective at dealing with traffic and congestion rather than continually expanding roads. Plus, you then get the side benefit of more safety and convenience for pedestrians and cyclists.

NHTSA asks states to wait on driverless cars

Posted on by

The federal government is asking states to wait on approving self-driving cars for general use until more research can be conducted:

The National Highway Traffic Safety Administration unveiled new recommendations to states for self-driving cars, urging them to be used only for testing and to require safeguards to ensure they can be taken over by a driver in the case of a malfunction.

NHTSA also said it was embarking on a four-year research effort on self-driving or autonomous vehicles as it considers requiring features like automatic braking, in which the car takes action to prevent crashes.

“We believe there are a number of technological issues as well as human performance issues that must be addressed before self-driving vehicles can be made widely available,” NHTSA said in its 14-page automated driving policy statement. “Self-driving vehicle technology is not yet at the stage of sophistication or demonstrated safety capability that it should be authorized for use by members of the public for general driving purposes. Should a state nevertheless decide to permit such non-testing operation of self-driving vehicles, at a minimum, the state should require that a properly licensed driver (i.e., one licensed to drive self-driving vehicles) be seated in the driver’s seat and be available at all times in order to operate the vehicle in situations in which the automated technology is not able to safely control the vehicle.”

NHTSA says as self-driving cars improve, they will reconsider. NHTSA says self-driving cars being tested in California, Florida and Nevada by Google and Audi of America should have the capability of detecting that their automated vehicle technologies have malfunctioned “and informing the driver in a way that enables the driver to regain proper control of the vehicle.” The Michigan Legislature is also considering allowing self-driving car testing…

Safety on the roads is an important concern but I’d be interested to see how much testing it might take for the government to approve self-driving cars. And, even if the safety appears to works out fairly quickly, will it take more time to reassure the public that such cars are safe?

It would also be interesting know how alert drivers are going to have to be while not driving. If the driver needs to be alerted to retake control, how relaxing is not driving going to be?

Wait, the good episodes of Arrested Development are like fully furnished McMansions?

Posted on by

One commentator suggests fans of the new season of Arrested Development should be patient and then makes an interesting comparison:

Stay cool, Internet. Arrested Development‘s new Netflix-delivered season may prove to be great yet.

Within hours of the streaming service dropping a 15-episode Bluth bomb, critics and fans rushed to proclaim the new episodes as substandard. Mere model homes instead of the fully furnished McMansions that they had watched and rewatched over the past few years. And while I certainly count myself amongst the fans who feel at least a wee bit disappointed by the new episodes, it’s still far too early to jump to conclusions about the episodes’ quality or legacy.

You see, Arrested Development is a unique show. While most sitcoms rely on simple setups and punchlines for their laughs, this is one show that runs amuck on the formula.Punchline often come before setups, and it’s not uncommon for objects to regularly flash across the screen and get call-backs several episodes (or even seasons) later. Basically: Many of the show’s jokes were simply not designed to make any sense the first time you see them.

As someone who has studied the use of the word McMansion, it is unusual to see someone making a favorable reference to McMansions. In this article, fans of Arrested Development are waiting for the “fully furnished McMansions” which are compared to the good episodes of the show. This is odd enough in itself. But, there is an extra twist. The show itself has commentary about McMansions. As Wikipedia puts it, “The Bluth family of the television series Arrested Development is in the business of building opulent-looking sub-quality housing.” Part of the show’s comedy is that this family who involved in a quintessential American industry, building homes, is so dysfunctional. They provide the American Dream but live a wacky version of American family life.

I also suspect that many fans of Arrested Development would not be fans of McMansions. The sort of arcane and long-form humor (see the running jokes here) of the show doesn’t exactly endear itself to the masses.

Five experts weigh in on global flight-path maps

Posted on by

An art critic, environmentalist, aviation consultant, data visualization expert, and philosopher offer some interpretations of global flight-path maps.

From the art critic:

It’s almost like contemporary fractalisation – based on fractals, those beautiful divisions of science and nature. A number of artists have exploited them. Max Ernst based a lot of his surreal landscapes on fractalisation.

From the aviation consultant:

Europe looks so bright because it has so many short-haul flights. It’s also one of the busiest global markets and there are several hubs in relatively close proximity in Europe: Paris, Frankfurt, Amsterdam and London…

What we’re going to see in a few years is more connections between Asia and Africa, and South America and Africa, along with more “south-south” trade.

From the expert in data visualization:

You can see the density of the flights, but it doesn’t show you how many people are travelling on them. You could do that by colouring them differently.

From the philosopher:

We are not seeing the life of individual human beings, but the life of the species as a whole, as if the species was one organism, pulsating like a jellyfish. Maybe it represents our collective existence?

Interesting thoughts all around. The quote above from the philosopher is right on in that maps like these allows us to see larger patterns and how we are all connected. It is not just about the flow of passengers or cargo back and forth but also about how these flight paths connect us. The maps could also serve as a proxy for global power and business activity. I remember seeing work from sociologist Zachary Neal along these lines. Take a look at his publications involving cities, networks, and airplanes here.
