The “science of shoveling”

Posted on by

Reading an article like this about the “science of shoveling” makes me glad that someone out there is seriously concerned about the best way to shovel:

The science of shoveling was invented by the Progressive Era efficiency expert (and father of Taylorism) Frederick Winslow Taylor. Taylor observed laborers shoveling varying weights and concluded that the shovel load with which “a first class man would do his biggest day’s work” was about 21 pounds. That’s remarkably close to the current recommendation from Canada’s Center for Occupational Health and Safety (keep per-shovel snow loads below 24 pounds). At the Bethlehem Steel works in Pennsylvania, Taylor gave out shovels specifically designed to hold 21 pounds—small ones for shoveling iron ore, big ones for shoveling ash—and made “thousands of stop-watch observations” to calculate the most efficient shoveling method.

Taylor’s purpose was not to preserve workers’ health but to maximize output; by following his recommendations, Bethlehem was able to increase the daily weight shoveled by each laborer from 16 to 59 tons. But because physical endurance was a necessary component to maximizing output, Taylor’s shoveling method also reduced wear and tear on the human body…

The other change is that, even taking into account that Taylor’s subjects were all experienced manual laborers, people must have had much stronger backs back then.Today, ergonomists worry less about manual laborers’ arms than about their backs, because the lower back (specifically the lumbosacral junction) is now understood to be the weakest link in the “body segment chain.” The same goes for anyone in the general population who shovels snow. Various technological innovations have been attempted to protect the back and reduce muscle strain generally, thereby lowering the risk of heart failure. A shovel with a longer shaft makes the initial part of the job easier, but it makes the part where you actually lift the snow harder. Many stores sell a snow shovel with a bent shaft, which is widely recognized as the optimal ergonomic design. This type of shovel has the opposite problem. It makes the initial part of the job harder (you have to stoop, especially if you’re tall or fat), but makes the part where you actually lift the snow easier.

It makes sense that Taylor is behind some of these ideas, particularly since shoveling was tied to manufacturing. I have seen these ergonomic shovels and may just have to purchase one after reading this in order to protect “the weakest link in the body segment chain.” So why aren’t there more strenuous advertisements for the health benefits of these ergonomic shovels?

In my shoveling yesterday, my technique was generally to use a smaller shovel (actually the biggest one we have but still relatively smaller) and lift and throw snow more frequently. I imagine the throwing motions I was using are not optimal – however, they were necessary in order to clear the four foot snow drifts that were already there. It sounds like I would be better off with a slightly bigger shovel so that I don’t have to lift as often.

And a couple of links in this story are interesting:

-Harvard provides some guidelines about shoveling. Basically, you shoveling may be problematic if you are out of shape or don’t exercise often, shovel first thing in the morning, and are exposed to extreme cold. (This is part of a full page about health for older men. Are older men the primary shovelers or are they are the ones most at risk?)

-One might wonder about the relative risk of shoveling: is this more dangerous than other activities? On the whole, heart attacks while shoveling represent a small proportion of the total heart-related deaths in the US each year: “The absolute risk of death-while-shoveling is low. An often-quoted statistic holds that 1,200 American die from a heart attack or other cardiac event during or after a blizzard every year, and that snow-shoveling is frequently to blame. This figure is sometimes attributed to the Centers for Disease Control, although an agency spokeswoman could not verify its source. Even if this statistic were correct, it’s nothing in comparison to the total number of annual heart-related deaths. According to the American Heart Association, there are 425,425 deaths per year from coronary heart disease.” That comes out to 0.3%.

Thoughts on plowing intersections, runs on bread, having places to turn around on major roads (like LSD), and more

Posted on by

Now that the Groundhog Day Blizzard of 2011 has stopped (though arctic wind chills are next), I have a few thoughts about the storm:

1. I drove home yesterday at about 4:45 PM. The roads weren’t too bad and the traffic was light – I assume this meant many people went home earlier. But there a problem in this sort of weather and any snow that always pops up: intersections that are difficult to move through. The roads can be quite passable but then everything bottles up at slushy intersections where people can’t start quickly and have great difficulty in turning. Someone needs to figure out a way to solve this problem. Would it be better to close an intersection for a minute or two so plows could do diagonal runs through the intersection square to clear snow? Are there people concerned about the science of plowing?

2. Why there was a run on bread in times like this is an interesting question to ponder. There are a lot of food one could buy before a storm hits that would be better in bread in that it would last longer and be more fulfilling. When did runs on bread begin and why do people still do this?

3. One of the stories in Chicago was the people who got stuck on in northbound traffic on Lake Shore Drive for hours. Why doesn’t every main road, particularly highways, have a certain number of points where people could turn around if a situation like this (or even a major crash in regular conditions) occurs? Lake Shore Drive has a number of exits in this area but those were blocked with crashes as well. Concrete barriers are helpful in separating traffic but this is an issue that someone should solve.

4. The warnings the police and state officials were giving overnight and this morning were intriguing that they must have to give these warnings because there are people who go out driving in such conditions when they don’t have to. This morning, one official suggested that if people wanted to go out, they needed to consider whether they were willing to risk their lives. This seems like common sense – but perhaps it is not.

5. When I woke up at 7:30 AM, the street in our residential subdivision wasn’t bad – perhaps 5-6 inches of snow. By 12:30 PM, a plow had done several runs on the street and it was clear. I was tempted to go drive and see what everything looks like but see point #4 above.

6. The blizzard is over – the total snowfall was the third biggest storm in Chicago history. Now it is time for the bitter cold. In the grand scheme of things, is the extreme cold more dangerous to more people than the blizzard conditions and the snow?

Exactly how many American homes are vacant?

Posted on by

Two bloggers have a disagreement about how many vacant homes there are in the United States. Check out the debate and the comments below.

The moral of the story: one still needs to interpret statistics and what exactly they are measuring. The different between 11% and 2% is quite a lot: the first figure suggests 1 out of 10 housing units are vacant while the second figure suggests it is 1 out of 50. If you look at Table 1 of this Census Bureau release regarding housing figures from Quarter 4, it looks like the vacancy rate is 2.7%. But there may be confusion based on Table 3 which suggests the vacancy for all housing units is roughly 11% for year-round units. And later in the release, page 11 of the document, gives the formula for the vacancy calculation and an explanation: “The homeowner vacancy rate is the proportion of the homeowner inventory that is vacant for sale.”

There are some other figures of note in this document. Table 4 shows that the homeownership rate is at 66.5%, down from a peak of 69.2% in the fourth quarter of 2004. (It is interesting to note that this rate peaked a couple of years before the housing market is popularly thought to have gone downhill. What happened between Q4 2004 and the start of the larger economic crisis? Table 7 has homeownership rates by race: the white rate has dropped 1.1% since 1Q 2007 while Blacks and Latinos have seen bigger drops (3.2% and 3.3%).

How the John Edwards affair became news

Posted on by

How exactly certain scandals come to light when they do is often an interesting tale. The former editor of the National Enquirer explains how his investigative team put together the story of John Edwards’ affair. The tale involves the use of technology and a profiler who provided insights into how to trap Edwards in his lies:

I knew there was no viable scenario for Edwards to confess to the Enquirer. I faced the bitter realization that another news organization would reap the benefits of our team’s hard work and get the confession, but I also knew that ultimately that confession would validate the Enquirer‘s earlier story as well as the new one.

Behind the scenes we exerted pressure on Edwards, sending word though mutual contacts that we had photographed him throughout the night. We provided a few details about his movements to prove this was no bluff.

For 18 days we played this game, and as the standoff continued the Enquirer published a photograph of Edwards with the baby inside a room at the Beverly Hilton hotel.

Journalists asked if we had a hidden camera in the room. We never said yes or no. (We still haven’t). We sent word to Edwards privately that there were more photos.

He cracked. Not knowing what else the Enquirer possessed and faced with his world crumbling, Edwards, as the profiler predicted, came forward to partially confess. He knew no one could prove paternity so he admitted the affair but denied being the father of Hunter’s baby, once again taking control of the situation.

Perhaps this story isn’t anything unusual – technology makes information gathering a lot easier. Yet it is somewhat shocking to me that plenty of powerful people, like John Edwards or Tiger Woods, think that they can get away with things in the long run. Sure, the National Enquirer had to spend months tracking down this story but in the end, it was doable and effectively changed the public perception of John Edwards forever. Is there something that happens when people are put in powerful positions that changes their perceptions of what they can and can’t get away with?

Is it even possible for the powerful to get away with things like this any more? How many “scandals” are lurking out there somewhere? It is certainly a far cry from the days of the 1950s and before when sportwriters routinely shied away from reporting on what athletes did away from home and political reporters didn’t talk about everything.

Pictures of “uncontacted” Amazon peoples

Posted on by

There are still areas of the planet where people have little contact with the larger world. The country of Brazil has just released photos of some people groups with limited contact in order to draw attention to their condition:

FUNAI has released similar photographs in the past and acknowledged that Peruvian loggers are sending some indigenous people fleeing across the border to less-affected rainforests in Brazil.

The coordinator of Brazil’s Amazon Indian organization COIAB, Marcos Apurina, said he hoped the images would draw attention to the plight of the indigenous peoples and encourage their protection.

“It is necessary to reaffirm that these peoples exist, so we support the use of images that prove these facts. These peoples have had their most fundamental rights, particularly their right to life, ignored — it is therefore crucial that we protect them,” he said.

FUNAI says there are 67 tribes in Brazil that do not have sustained contact with the outside world. Some are often referred to as “uncontacted” tribes even though they have some kind of, albeit limited, contacts.

The future of a number of these groups has been threatened in recent decades primarily by people who want their land, either for its natural resources or who want to convert it into farmland. And there are some interesting discussions about how these cultures can continue to remain fairly distinct from outside influences, even if most now have had some contact with the larger world.

Comments on whether Evangelicals are generous enough

Posted on by

A number of commentators, including a few sociologists (Christian Smith and Bradley Wright), weigh in on the question of whether Evangelicals are generous or stingy with their money.

Two points to take away:

1. Evangelicals are more generous than many people.

2. Evangelicals don’t come close to giving to their full capacity, let injunction the idea of giving 10% of their income.

Quick Review: Da Bears!

Posted on by

Partly to commemorate the Chicago Bears’ lone Super Bowl title and also to help mourn the recent loss to the Green Bay Packers, I read Da Bears!: How the 1985 Monsters of the Midway Became the Greatest Team in NFL History. A few thoughts about this book, one of many products commemorating this 25th anniversary:

1. A main theme of the book is the ongoing battle between Head Coach Mike Ditka and defensive coordinator Buddy Ryan. How exactly the team kept moving forward with this kind of tension is interesting.

2. There are claims that the Bears were the team that really helped push the NFL to the top. With their winning plus the actions and charm of their players, the Bears were a kind of media circus in an era where this didn’t happen often.

2a. The problem with a claim like this is that little evidence is presented that might conflict with this narrative. At one point, the book mentions that several teams had recorded songs as teams before the “Super Bowl Shuffle” but it was this 1985 song that really took off. Another (implicit?) claim is that the Bears really pushed athlete endorsements forward. Were other star athletes not doing commercials? In the end, how exactly do we know the Bears were something different in the eyes of the media compared to any other team of the time? I would have liked to have read more perspectives from outside of Chicago – were people across the country as intrigued with the Bears as Chicagoans were?

3. Some things never seem to change with the Bears: defense over offense, inconsistent quarterback play, complaints about the McCaskeys, an inability to follow up on success (with the 1985 Super Bowl team never getting back to another title game), fickle fans who suddenly were worried at the end of the 1985 season with less than perfect play, and more. How long can a team have the same basic identity?

4. As a cultural phenomenon, it would be interesting to track other teams that have captured the heart of a city in the same way as the Bears. While the list of endorsements and radio shows during the 1985 season was impressive, many of those guys are still around in the Chicago media. Will there be a point where the 1985 team is eclipsed by another team or was their combination of dominance and style too much to overcome?

5. It was unclear to me how much of this book was original research versus drawing from existing sources.

Overall, I’m not sure how much new material this book presents: many of the themes are widely known. There are a wide range of perspectives in this book but I think you also find this information elsewhere. I was looking for a new take on a famous team and yet you will hear the same things on local sports talk stations and other media.

Why we talk so much about the weather

Posted on by

The headline at ChicagoTribune.com: “Blizzard may be ‘life threatening.’” There were similar headlines throughout the day on the front page of Yahoo! (with the latest version of the story here). Yes, there are predictions for a big storm but why do we talk about the weather so much?

My own thoughts: for the average American adult, the weather is perhaps the only constant in our days that we feel we can’t control. With a certain level of income, most Americans can handle day-to-day matters pretty easily: food is easy to obtain, we have generally large and nice shelters, transportation (by car) is available to many, jobs are decent and give us something to do (even with recent higher unemployment figures). Wars are distant and we know that many in the world face much tougher conditions. But we can’t control the weather. A blizzard bearing down on us reminds us that there are some areas in life of which we can only respond. There is a Christian theme in here if we take a moment to ponder it: we are ultimately not in complete control of our lives, this is okay, and perhaps we should remind ourselves of this more often.

(Additionally, the weather is a common, safe topic that can pull people together. It is hard to be offensive or rude when bringing up the weather. Since we all have to deal with it, it can help bring about group solidarity if we have a neutral topic to fall back on.)

The morality of going to the gym

Posted on by

The adult life is often made of up little tasks that must be done to live: go to work, prepare and eat meals, do laundry, and various other activities. Perhaps there is another activity that must be added to this list: getting exercise and/or going to the gym.

“There seems to be a whole substitute morality, where your obligation is to go to the gym and not ask why,” says Mark Greif, a founding editor of the literary journal n+1 and the author of a widely discussed 2004 essay, “Against Exercise.” “If you don’t, you become a sort of villain of the culture.”

The message that perspiration is a gateway to, and reflection of, higher virtues is captured in health club slogans like ones used by the Equinox chain over recent years: “Results aren’t always measured in pounds and inches.” “My body. My biography.” “It’s not fitness. It’s life.” The same idea is encoded in the language of personal improvement. A “new you” usually means a trimmer, tauter version, not someone who has learned to speak Mandarin or picked up woodworking skills.

And the pectoral is political. The current president and his predecessor have made ostentatious points of their commitments to fitness routines. Whatever the differences in their ideologies, intellects and work habits, George W. Bush and Barack Obama both let voters know that they carve out time almost daily for cardio or weights or both. And while that devotion could be seen as evidence of distraction (Bush) or vanity (Bush and Obama), each politician safely counted on a sunnier takeaway. In this country, at this time, steadiness of exercise signals sturdiness of temperament, and physical leanness connotes mental toughness…

To be unfit is to be unfit: a villain of the culture, indeed.

An interesting commentary. More broadly, these ideas seemed tied to American ideals of youth and health. We like politicians and athletes and movie stars who are physical specimens. We argue that disciplining the body is indicative of discipline in other areas of life. Being healthy is not just being an appropriate weight or eating right or limiting stress: it should include muscles and toning.

Some questions follow:

1. Do other cultures have similar ideas or are we unusual in this regard?

2. When or where did the emphasis on muscles, beyond just “being fit,” arise?

3. For the average American, how much of this judgment regarding exercise and going to the gym comes from people around them versus comparing themselves to media produced images?

4. How much have professional sports contributed to this? If you look at athletes in the 1950s and 1960s, they did not train as much. Today, being an athlete is a full-time, full-year job in order to stay in shape.

Comparing pollution in cities versus suburbs

Posted on by

The Infrastructurist sums up a new study that compares pollution generated in cities versus that produced in the suburbs:

To illustrate this point, the authors of the new report examine per capita emissions rates in three locales in the greater Toronto region. The lowest per capita emissions rate (1.31 tons of carbon) belonged to the inner-city neighborhood of East York, home to dense apartments within walking distance of a commercial center and public transit. The highest rate (13.02) was found in Whitby — pictured at the top of this post — a sprawling suburb whose residents rely on automobiles to reach the shopping districts. Splitting the difference was Etobicoke (6.62), an area full of single-family homes but still accessible to the downtown core via public transportation.

The authors conclude:

The most important observation is that there is no single factor that can explain variations in per capita emissions across cities … .

An equally important observation, I might contend, is that the conversation about reducing emissions shouldn’t stop at the city limits.

It would be interesting to know what the authors then recommend.

But the larger issue still seems to be how to convince suburbanites that this pollution and emissions issue is a big enough one that they should change their behavior. Is some more pollution worth it to have the personal freedom and autonomy of living in a suburban, single-family home where you can drive in your car from place to place?
