Reassessing Mead versus Freeman in their studies of Samoa

Posted on by

A new look at anthropologist Derek Freeman’s critique of Margaret Mead’s famous study of sex in Samoa suggests Freeman may have manipulated data:

But Shankman’s new analysis — following his excellent 2009 book, The Trashing of Margaret Mead: Anatomy of an Anthropological Controversy — shows that Freeman manipulated “data” in ways so egregious that it might be time for Freeman’s publishers to issue formal retractions…Now Shankman has delved even deeper into the sources; in 2011, he obtained from Freeman’s archives the first key interview with one of the supposed “joshing” informants, a woman named Fa’apua’a. This interview, conducted in 1987, allegedly bolstered Freeman’s contention that Mead had based her “erroneous” portrait of Samoan sexuality on what Fa’apua’a and her friend Fofoa had jokingly told Mead back in the 1920s.

But Shankman shows that the interview was conducted and then represented in deeply problematic ways. The 1987 interview with Fa’apua’a was arranged and carried out by Fofoa’s son, a Samoan Christian of high rank who was convinced that Mead had besmirched the reputation of Samoans by portraying his mother, her friend Fa’apua’a, and other Samoans as sexually licentious…

But why did Freeman get it so wrong? Shankman’s book suggests Freeman was obsessed with Mead and with what he saw as her dangerous stories about the flexibility of human cultures. He saw himself as a brave “heretic,” a man saving true science from Mead’s mere ideology.

I wonder if Shankman’s work is the start to a solution to this debate. If two anthropologists disagree so much, wouldn’t bringing in other anthropologists to review the data or conduct their own fieldwork a possible answer to adjudicating who got it more right? There is a time factor here that makes the issue more complicated but people in addition to Shankman could review the notes and comparisons could be made to other societies which might be similar and offer insights.

More broadly, I wonder how much incentive there is for researchers to follow up on famous studies. Freeman made a name for himself by arguing against Mead’s famous findings but what if he had gone through the trouble and then found Mead was right? He likely would not have gotten very far.

 

Is downtown Naperville really unsafe at 10 PM?

Posted on by

Is downtown Naperville an unsafe place? According to the Naperville chief of police, recent efforts by the department and other interested parties have helped make the downtown safer late at night:

Naperville police Chief Robert Marshall is just five months into his revamped downtown enforcement plan and he and city leaders already are calling it a success…

Beginning in September and running through mid-January, four additional officers were moved downtown between 10 p.m. and 3 a.m. Fridays and Saturdays to focus on disorderly conduct issues, public intoxication and urination, and underage drinking. According to Marshall’s memo, the officers contributed 591 hours of additional police coverage and cost the city nearly $35,000 in overtime costs.

“Last year we had a tragic murder, an armed robbery and two very violent beatings that sent all participants to the hospital,” Marshall said. “As far as violent crimes go, that is a very low number, but our goal is zero. And in the five months since we’ve enacted our plan (in September), that’s exactly what we have.”…

“There is a perception that it’s not safe to come downtown after 10 p.m.,” Pradel said. “Our police are doing their part and we’ve told the business community they are also responsible to make that perception go away.”

I am particularly interested in this quote from Naperville’s mayor who discusses the perception about Naperville’s downtown late at night. This violence could be quite jarring in a community like Naperville that is both quite wealthy and quite safe for a community its size. Who exactly is worried about the downtown at night? Perhaps it is Naperville residents who like the residential nature of the suburb and buy into the small town charm leaders claim Naperville possesses. Perhaps it is possible visitors who will take their money elsewhere. In these sorts of discussions, I haven’t seen any numbers about a downturn in business in Naperville – is this about perceptions or an actual loss of business?

Overall, this seems to come back to an issue I’ve raised before: how can a community like Naperville (and other upscale suburbs face similar issues – see here) both encourage business and cultural activity while also protecting the residential charms of their community? Bars and restaurants can bring in large amounts of money into city coffers. Many communities would love to have the number of restaurants and visitors that Naperville attracts. Yet, this can also bring trouble, particularly when bars are involved.

For now, Naperville leaders seem happy with their new approach that minimizes violence but keeps the money flowing in. Perceptions and reputations are important as suburbanites can spend their money in plenty of places other than Naperville.

Evaluating the charts and graphics in President Obama’s “enhanced experience” version of the State of the Union

Posted on by

In addition to the speech, President Obama’s State of the Union involved an “enhanced experience” with plenty of charts and graphics. Here are some thoughts about how well this data and information was presented:

But sometimes, even accuracy can be misleading, especially when it comes to graphics and charts. On Tuesday night, President Obama gave his State of the Union address and the White House launched an “enhanced” experience, a multimedia display with video, 107 slides and 27 charts…

Overall, Few said Obama’s team created well-designed charts that presented information “simply, clearly and honestly.”

On a chart about natural gas wells:

“This graph depicting growth in natural gas wells suffers from a problem related to the quantitative scale, specifically the fact that it does not begin at zero. Although it is not always necessary to begin the scale of a line graph at zero, in this case because the graph was shown to the general public, narrowing the scale to begin at 400,000 probably exaggerated people’s perception of the degree in change.”

On a chart about “energy-related CO2 emissions”:

We found that the data behind this chart match up with what the U.S. Energy Information Administration reports in its table of U.S. Macroeconomic Indicators and CO2 Emissions. But the y-axis is too compressed and as a result the chart exaggerates the trend a bit.

On a chart about American troop levels in Afghanistan:

Annotating discrete data points as this chart does can be helpful to tease out the story in a bunch of numbers, but that’s not a replacement for properly labeled axes. And this chart has none.

It seems like the data was correct but it often was put into a compressed context – not surprisingly, the years Obama has been in office or just a few years beforehand. This is a basic thing to keep in mind with charts and graphs: the range on the axes matters and manipulating these can change people’s perceptions of whether there have been sharp changes or not.

In response to emergencies, companies seek out more distribution centers

Posted on by

A number of companies are now pursuing a new distribution center strategy in order to be better prepared for disasters and other disruptions:

Major storms like Hurricane Sandy and other unexpected events have prompted some companies to modify the popular just-in-time style of doing business, in which only small amounts of inventory are kept on hand, to fashion what is known as just-in-case management.v

The shift has led retailers and logistics companies to alter supply chains by adding distribution hubs, according to the CoStar Group, a real estate research firm in Washington. In turn, the hubs are creating real estate opportunities in markets on and off established distribution paths, including growth in markets outside the traditional seaport hubs on the East and West Coasts…

Just-in-case is a response to the vulnerability of just-in-time supply chains, said Rene Circ, CoStar’s director of industrial research. Since the 1990s, just-in-time has made sense for many companies looking to reduce the cost of keeping large inventories on hand. Technology enabled retailers and manufacturers to closely track and ship items to replace merchandise sold or components consumed in production…

The tendency toward numerous distribution facilities runs contrary to a strategy that was common just after the recession, when some companies sought efficiency by consolidating warehouse operations, according to Bob Martie, executive vice president for the New Jersey region at Colliers International, a real estate service provider.

Consumers may not pay much attention to this distribution chains. In fact, they may only really notice them when major events disrupt them. However, the distribution system is incredibly important for the American consumer economy. The reason products are on the shelves when consumers want them is due to this. Companies argue more efficient systems help them keep costs down. Better planning can reduce truck traffic on local roads.

This article adds another twist to the distribution center story: there is money to be made in distribution center real estate. Perhaps quite a bit of money.

Trying to save a Sears home in Oakbrook Terrace

Posted on by

Historic preservation is a common topic in older suburbs and one effort in Oakbrook Terrace features a more unusual Sears home:

The city purchased the house of the late longtime city clerk Lorraine Fik in 2008 with plans to demolish it to create a retention pond when it builds a new police station east of city hall. That work is expected to start this summer.

Saving the house, located across from city hall at 17W245 16th St., would require the city to provide water retention by other means, such as under the police station — a more costly option.

The move to preserve the house began after the recently formed historical society contacted architectural historian Rebecca Hunter of Elgin, who found proof of the home’s authenticity in the markings on the basement floor joists. The prefabricated home was built by Lorraine Fik’s husband, Edward, around 1950, and Lorraine had her clerk’s office in the basement until the city got a building of its own.

Kelly Fik, Lorraine’s youngest son, provided the historical society with photos of the house being delivered by truck and read a letter from the Fik family at Tuesday’s city council meeting.

These mail order Sears homes were produced in the early 1900s. Here are some more examples of Sears homes from the Chicago suburbs. On one hand, such homes are unusual and prior to the post-World War II era, mass produced homes were more rare. The era of the large-scale builder had not yet arrived. On the other hand, the homes don’t appear to be too unusual. Why save these homes just because they happened to come through a catalog over other homes built in the same era?

Another note: it is interesting to look at some of these examples and see how people have altered the Sears homes over the years.

Zappos CEO says office space should be designed like cities

Posted on by

Zappos CEO Tony Hsieh argues office space would work better if it were organized like cities:

Tony Hsieh talks about his Internet juggernaut Zappos in the same way that urban planners talk about cities. In fact, the language is uncanny. He believes the best ideas – and the best form of productivity – come from “collisions,” from employees caroming ideas off one another in the serendipity of constant casual contact.

This is only achievable through density, with desks pushed close together in the office, or – in the case of Hsieh’s ambitious plans to leverage the new Zappos headquarters to remake downtown Las Vegas – with company employees and community members colliding into each other on the street. For the kind of “collisionable” density he’s looking for in downtown Vegas around his company, he figures the neglected area (not to be confused with the Vegas Strip) needs at least 100 residents per acre…

The typical office has about 200 or 300 square feet of space per employee. When Zappos moves into its new headquarters in the former Las Vegas City Hall in about six months, Hsieh is aiming for something closer to 100 square feet per employee. He’s also planning to decommission a skywalk into the building to force people to enter through (and collide with) the street.

In the context of offices, this kind of density bucks conventional wisdom. Most companies think employees will perform best, or at least be happiest, if as many of them as possible can have their own spacious corner office (with closable door!). This thinking has even influenced the architecture of office towers.

“That’s analogous to people wanting to live in the suburbs and live in a big house,” Hsieh says. “And what they don’t realize is that they end up trading two hours of commute time for more time with friends or relaxing or whatever.”

Interesting comparisons: corner offices are like suburbs. While Hsieh cites research, how come other companies haven’t figured this out yet? I also wonder if this is more about corporate cultures established in more traditional firms versus newer startups or high-tech firms. This reminds of a video I show in my Introduction to Sociology class to illustrate the differences between more bureaucratic structures and more flat, disc-shaped structures. In the clip from Nightline, the design firm IDEO is shown working through designing a new shopping cart. The atmosphere is both less hierarchical in terms of authority and space; people seem to be closer together and common collaborative space is important.

This conversation also lines up with talk on college campuses about interdisciplinary research and collaborative activity. Just how much can redesigned offices and common spaces contribute to this? Are we missing something major by building office buildings more like suburbs than cities?

People in mosh pits act predictably like gas molecules

Posted on by

A graduate student in physics argues the behavior of people in mosh pits is similar to that of gas molecules:

Being a physicist first and a mosher second (“fieldwork was independently funded”), the student, Jesse Silverberg, can’t help but notice curious patterns in what had always felt like the epitome of chaos. “Being on the outside for the first time, I was absolutely amazed at what I saw — there were all sorts of collective behaviors emerging that I never would have noticed from the inside.” So for an even better perspective, he turns to YouTube, to figure out what happens to people under the “extreme conditions” borne of a combination of “loud, fast music (130 dB, 350 beats per minute) … bright, flashing lights, and frequent intoxication.”

What he found, of course, was the “collective phenomenon consisting of 10^1 to 10^2 participants commonly referred to as a mosh pit.” And he was able to prove his initial observation: While the individual movements of moshers may be random, their collective behavior follows a few simple rules…

Look familiar? Moshers, as they “move randomly, colliding with one another in an undirected fashion,” seem a lot like gas particles, the researchers note. Or, as Silverberg explained to me: “It turns out that the statistical description we use for gasses matches the behavior of people in mosh pits. In other words, people bounce around like the molecules in a gas.” And they can be understood using the same basic principles we use to study those molecules.

Using videos of heavy metal concerts, write the authors, allows them to study crowd behavior in a way that staged experiments haven’t been able to. According to Silverberg, the unique circumstances (re: loud music and intoxication) of mosh pits are applicable to other instances of collective motion, like riots or emergency situations, where panicked crowds tend to break into random, slightly hysterical motion. Better understanding their dynamics might serve to improve safety measures in buildings or stadiums. If nothing else, they may serve as a useful reference to EMTs in the very pits where the research originated (per one study, 37 percent of injuries that took place over the course of a four-day music festival were “related to moshing activity”).

Interesting research. While many may not typically think of physics providing insights into social interaction, a lot of good work has emerged from physics in recent decades on social networks.

This is a funny statement: “the fieldwork was independently funded.” It could be even better if an independent granting agency was willing to fund such research with mosh pits to develop insights into collective behavior. If the project was pitched at looking for insights into safety with such crowds, I imagine some funding could be found.

Argument: rural American voters are being disenfranchised

Posted on by

A member of the Hoover Institution argues rural Americans are losing their right to self-governance:

With each passing election, rural and small town Americans have ever less influence on their state and national governments and ever declining control over the governance of their own communities. Their lives are increasingly controlled from distant state capitals and from the even more distant Washington, D.C., by politicians with little incentive to pay attention to their country cousins. To some extent, their disenfranchisement is the inevitable result of a century of urbanization and economic centralization. But the erosion of self-governance in rural America is also the result of a generally well intentioned but simplistic understanding of democracy and the associated elimination of institutional protections of local democratic governance.

Two ideas have been central to this effective disenfranchisement of rural America. First, that one person/one vote is an inviolable principle of democratic government under the United States Constitution. Second, that the winners of elections owe allegiance only to those who voted for them, no matter how close the margin of victory…

The reality is that rural communities have experienced a declining influence on state governance ever since reapportionment was first mandated in the 1960s. Many will say that this is as it should be. Rural and small town voters constitute minorities in every state, and minorities are supposed to lose in a democracy. But that is the same argument made against the Electoral College, given the possibility that a candidate who wins the popular vote might lose in the Electoral College, and it is an argument that also would condemn the much greater counter-majoritarian nature of the U.S. Senate.

Different and diverse majorities in each state are combined in the U.S. Senate to pursue national policies that are truly national and not just what will serve the interests of the nine states in which the majority of the nation’s population resides. There is no similar safeguard at the state level for different and diverse majorities in small town and rural communities that happen to constitute the red regions of the blue states—though there once was.

Prior to the 1964 United States Supreme Court decision in Reynolds v. Sims, most state legislatures included one house apportioned on the basis of population and a second chamber apportioned on the basis of counties or other geographical regions. Many of the former had not been reapportioned for decades, leaving growing urban areas with less representation per capita than rural regions. On the basis of the principle of one person/one vote, the Court found that the failure of most states to regularly reapportion their lower houses put them in violation of the equal protection clause of the 14th amendment.

The first thing I thought of when reading this argument was that this is a long-standing tension in American history. Thus, we have mechanisms in national government that are meant to limit some of this. From the beginning, the interests of the more urban North were pitted against the interests of the more rural South. These issues still remain even though the geography has changed since then in several important ways: there are plenty of rural areas in mid-America as well as in the West and we have a broad middle category, actually the most populous space for Americans to live, called the suburbs. Additionally, party lines have shifted.

But, we could take this in another direction and think more creatively about how to select elected officials. Huffman argues the Supreme Court limited the voice of rural voters in states when it went to a system of officials per population rather than by geographical boundaries. What might happen if we went to a system where districts were drawn only within a single geographic group: cities, suburbs, and more rural areas? Huffman seems to be suggesting that the interests of a city-dweller in Chicago or Atlanta may be much similar to each other than representatives across northern Illinois where there districts can cover all three geographic types. Suburban legislators across metropolitan regions or states might have similar interests compared to those who represent other types of geographies.

I just have to ask: would conservatives be arguing for the voters in rural areas if it were primarily Democrats in rural areas as opposed to Republicans?

Reformatting a zoning map of Chicago to look like SimCity 2000

Posted on by

Zoning maps can include a lot of categories but what happens if it is converted to a SimCity 2000 format? Check out this recolored Chicago zoning map:

To spice up their interactive “2nd City Zoning” map of Chicago, Derek Eder, Juan-Pablo Velez and Aya O’Connor paid tribute to the SimCity franchise with some familiar color-coding. Blue for commercial, yellow for industrial, green for residential.

Then they got carried away, incorporating a few choice icons from SimCity 2000 as well as some of that legendary game music, which you can listen to while you browse the map.

Zoning is a little more complicated than the tri-color scheme implies, but by the time you get to the portion of the site that explains the difference between Manufacturing and Planned Manufacturing Districts, it’s mission complete for the designers.

Here are more details of the SimCity change from 2nd City Zoning – including a plea to not be sued.

It is too bad there isn’t a longer discussion about the simplicity of SimCity zoning versus real world zoning. Are there benefits to presenting a simpler zoning map to residents? (This assumes that there are a good number of residents that want to look at such maps.) How much complexity compared to real life was SimCity missing in the 2000 version? SimCity players might have learned something by playing the game but might also have been misled by the reductionism.

The music takes me back…

Supersized McMansions, supersized roses for Valentine’s Day

Posted on by

I’ve seen McMansions compared to a number of other large consumer items, but until today I had not seen a comparison to flowers:

Leave it to America, land of the Big Gulp, Monster Burger and McMansions, to supersize yet one more thing: the rose.

Make that a six-foot rose, just in time for Valentine’s Day.

This flower-on-steroids — it actually gets this big from special breeding and soils — comes courtesy of several companies, including FTD, The Ultimate Rose and FiftyFlowers.com. Sales are taking off as florists promote the gargantuan blooms, which also come in three-, four- and five-foot varieties. The companies won’t release exact numbers, but FTD says sales have increased 50% year over year since it started selling the roses four years ago…

Skaff says FTD has already sold out of the five-foot variety and had to order more to meet demand ahead of Valentine’s Day. The Ultimate Rose, which supplies the giant roses to FTD and also sells them on its own site, says sales jump this time of year.

The suggestion here is that the presence of McMansions is related to the presence of six-foot tall roses through the desires of Americans for both because they are large. This seems like a bit of a stretch to me; are the same people buying McMansions and large roses? Are both solely about standing out from the crowd? Overall, this seems like a journalistic shortcut of recent years: when an item becomes larger, compare it to McMansions (and perhaps SUVs and Big Gulps might be other apt comparisons). What items if an item becomes smaller – is there a similar go-to comparison?
