Embedding traffic lights in sidewalks to help pedestrians

Posted on by

Incessant smartphone use is leading to urban adaptations:

That is why officials in the city of Augsburg became concerned when they noticed a new phenomenon: Pedestrians were so busy looking at their smartphones that they were ignoring traffic lights.

The city has attempted to solve that problem by installing new traffic lights embedded in the pavement — so that pedestrians constantly looking down at their phones won’t miss them.

“It creates a whole new level of attention,” city spokeswoman Stephanie Lermen was quoted as saying. Lermen thinks the money is wisely spent: A recent survey conducted in several European cities, including Berlin, found that almost 20 percent of pedestrians were distracted by their smartphones. Younger people are most likely to risk their safety for a quick look at their Facebook profiles or WhatsApp messages, the survey found…

But city officials say their work is justified: The idea to install such traffic lights came after a 15-year-old girl was killed by a tram. According to police reports, she was distracted by her smartphone as she crossed the tracks.

The direction of change is with the smartphone users: their safety matters and urban planners and officials must adjust.

I assume the future self-driving cars will be able to communicate with smartphones (or whatever devices we are all sporting at that point) to protect cars from the pedestrians. At that point, the cars will be far safer than the zombie or distracted or unpredictable activity of any pedestrian.

Internet headlines and stories present a disconnected world; a pitch for sociology

Posted on by

Whether you read headlines on the Google News page or the Drudge Report or the front page of Yahoo, Internet headlines and stories tend to provide very small slices of reality. Want to see the actions of a happy cat? How about the strange actions from someone with mental illness? What one C-list celebrity did last night? The inane “gaffe” from the campaign trail earlier today? Put all of these headlines together, some serious and many not, and what do you get? It is difficult to get a broad, cohesive view of the world from Internet stories. They can provide more information than people in the past ever had and let us know how many different people around the world live. Even good stories on websites devoted to more in-depth news present numerous topics. Yet, because of their fleeting, diversionary, and never-ending nature, they don’t add up to much. As a reader, how am I to put all the pieces together?

It is debatable how much better other forms of media do in delivering broader context and the bigger picture. Media forms composed of images – TV, films – have moved toward incredibly quick editing so that scenes rarely last more than a few seconds. Written forms – newspapers, magazines – have a reputation for deeper storytelling. Yet, this all assumes that a good number of citizens take the time to read such materials and understand them.

Perhaps this is where we don’t just need media or digital literacy; we need ways to put all the information together and keep the big picture in mind. What is underlying all these stories? What are the patterns in society? Why do these stories get attention and others do not? Sociology can help: you need to know the broader context, the powerful institutions at work in society, how information is created and sold, and the large-scale social trends. One story of an amazing animal tells us nothing; having tens of thousands of such tales might. Reading multiple stories about the Panama Papers might be interesting but we need to know how this intersects with all sorts of social systems (such as governments and corporations) and processes (such as social class and globalization).

It is too easy to get caught up in the quick accumulation of news and information without stepping back and trying to comprehend it all. We are good now at dispensing information but having difficulty digesting. We need frameworks in which to put the new headlines and stories. We need time to consider how this new information might affect us. All of this takes time and effort on the part of individuals – perhaps it is just easier to let all the information wash over us. But, even if we must do this at times, having a sociological perspective that sees social structures and forces and asks for empirical evidence could help us all.

(Disclaimer: I occasionally think about how to pitch sociology to undergraduates and this is one such attempt.)

Google exploring constructing their own city

Posted on by

A new Google city would allow the company to test ideas:

The boss of Sidewalk Labs, the firm’s New York City firm described as an ‘urban innovation’ company mentioned the idea at a summit hosted by The Information. 

‘Thinking about a city from the Internet up is really compelling,’ Sidewalk CEO Dan Doctoroff said at the event…

Later he added that building a new city could help test solutions to cybersecurity and privacy issues: ‘If you could create a place, it’d be a laboratory to experiment with these problems.’…

‘Sidewalk will focus on improving city life for everyone by developing and incubating urban technologies to address issues like cost of living, efficient transportation and energy usage,’ chief executive Larry Page said in a post at the Internet titan’s Google+ social network.

On the one hand, it would be difficult to test certain products – like a self-driving car – without having your own city that mimics real life.

On the other hand, I could see certain issues arising:

  1. If people lived in this city, what kind of rights would they have?
  2. For those who are already worried about the lack of public spaces in many big cities, what about a big city owned by a globally powerful corporation?
  3. Could such a model of corporations building cities offer benefits such that they become more attractive than what we have now where cities are theoretically for residents?

Tool to help urban strangers converse, make eye contact

Posted on by

Several researchers are working on the Jokebox, an invention intended to promote social interaction in cities:

Mara Balestrini, an expert in human-computer interaction and director of research at Ideas for Change, has been investigating ways to bring shared experiences back into public spaces. She’s been working with researchers from the UK and Mexico on the Jokebox project – an installation that involves separate wooden boxes, each equipped with speakers, sensors and arcade-style buttons, that tell a joke when two people activate them simultaneously.

The key, Balestrini tells me, is that it’s impossible for one person to push both buttons. “The Jokebox is an ice-breaker, an excuse to get strangers to talk to each other or to share a laugh in public spaces,” she explains. “It is also a technology prototype that can help us understand how to design novel interfaces to foster social connectedness in urban settings by encouraging eye contact and co-operation between strangers.”

As part of their study, the researchers conducted a series of tests in the north-western Mexican city of Ensenada. Boxes were set up in a park, a shopping centre and a bus stop. According to the project’s findings, people in those settings reacted in different ways – kids and parents would be more likely to play with the boxes in the park, for example, whereas teenagers were more likely to engage in the shopping centre. Even when people avoided using the Jokebox directly, which was frequently the case at the bus stop, it still provided an excuse for interaction – as is the case in this moment of gentle warmth….

Balestrini tells me future cities will combine different types of technologies, from those that support efficiency by replacing the humans to those that try to foster shared encounters among people. She says it is crucial to enable playfulness and curiosity, particularly in a moment where the discourse around cities revolves around ideas of data-driven automation and efficiency.

It is interesting to consider that it might be technology that could help bring people back into conversation. Is this the best we can do in societies thrilled with technological progress and private space (even when we are in public)? How successful might this be in drawing people out of their private realms or will it primarily appeal to those who are already more interested in social interaction? I’m not surprised that this device uses humor, a social phenomena that can cut across all sorts of social divides. At the same time, the humor has to be broad and affirming rather than the critique and sarcasm that is very common today.

Real estate agents and steering today

Posted on by

Many real estate agents today won’t answer certain questions but does this eliminate steering?

Agents such as Foster and Thakkar are hypersensitive because they don’t want to run afoul of the Fair Housing Act, which prohibits discrimination on the basis of race, color, religion, gender, national origin, familial status, disability or handicap. The law is administered by the Department of Housing and Urban Development. Penalties for violating fair housing rules can be costly, so many real estate brokerage firms train agents on what constitutes “steering” of homebuyer clients as well as what could be interpreted as showing any form of bias against any “protected class.”

What can agents do when clients ask certain questions? Here are several of the examples provided:

“We can’t answer,” Foster said. “It’s all too subjective.” Instead, she refers them to online information sources about whatever they’re asking — websites that rate schools, statistical compilations on crime rates and the like…

“It’s a very common question,” he says: “Can you tell us how many other Indian families live on this street?” Even though he thinks he understands the thrust of the question — are there people like us around? — he declines to answer directly. Instead, he supplies them a list of the names of current owners on the street, allowing his clients to decide for themselves whether the names indicate that they are Indian or not.

Referring people to other sources may lead to issues:

But some fair housing advocates are concerned that the online information available today may actually enable a subtle form of racial steering when agents name specific sites that offer highly localized racial and ethnic breakdowns and refer clients to them. Lisa Rice, executive vice president of the National Fair Housing Alliance, a nonprofit group that has fielded teams of white and minority “testers” to detect bias in homes sales, thinks that in the event of fair housing complaints against those agents, the fact that they made such specific referrals could be held against them.

It seems to me that one of the best ways to eliminate this issue is to educate homeowners about all the potential information they can access. Stop them from asking in the first place. Realtors could even make this clear at the beginning. The Internet certainly presents a lot of available information to possible home buyers ranging from the Census to other data aggregators to message boards to municipal websites. In other words, it is not hard to find out this sort of information. Yet, this would go against the argument that realtors make about why they are still necessary: they have inside information about the home and the entire process. Additionally, all the online information is not necessarily easy to interpret. Say a homeowner is interested in future property values: can they make a prediction based on what is online? Or, say that an online message board suggests one thing is happening while the local newspaper claim something else is taking place. How could someone unfamiliar with the area make a judgment regarding conflicting information?

In the long run, if people want to fight residential segregation and housing discrimination (which are legitimate concerns), would it be better to remove real estate agents from the process or not?

Get back to the actual behavior in the science of behavior

Posted on by

An interesting look at the replicability of the concept of ego depletion includes this bit toward the end about doing experiments:

If the replication showed us anything, Baumeister says, it’s that the field has gotten hung up on computer-based investigations. “In the olden days there was a craft to running an experiment. You worked with people, and got them into the right psychological state and then measured the consequences. There’s a wish now to have everything be automated so it can be done quickly and easily online.” These days, he continues, there’s less and less actual behavior in the science of behavior. “It’s just sitting at a computer and doing readings.”

Perhaps, just like with the reliance on smartphones in daily life, researchers are also becoming overly dependent on the Internet and computers to help them do the work. On one hand, it certainly speeds up the work, both in data collection and analysis. Speed is very important in academia where the stakes for publishing quickly and often continue to rise. On the other hand, the suggestion here is that we miss something by sitting at a computer too much and not actually analyzing behavior. We might take mental shortcuts, not ask the same kind and number of questions, and perform different analyses compared to direct observation and doing some work by hand.

This reminds me of a reading I had my social research students do last week. The reading involved the different types of notes one should take when doing fieldwork. When it came to doing the analysis, the researcher suggested nothing beat spreading out all the paper notes on the floor and immersing oneself in them. This doesn’t seem very efficient these days; whether one is searching for words in a text document or using qualitative data analysis software, putting paper all over the floor and wading through it seems time consuming and unnecessary. But, I do think the author was right: the physical practice of immersing oneself in data and observations is simply a unique experience that yields rich data.

Census 2020 to go digital and online

Posted on by

The Census Bureau is developing plans to go digital in 2020:

The bureau’s goal is that 55% of the U.S. population will respond online using computers, mobile phones or other devices. It will mark the first time (apart from a small share of households in 2000) that any Americans will file their own census responses online. This shift toward online response is one of a number of technological innovations planned for the 2020 census, according to the agency’s recently released operational plan. The plan reflects the results of testing so far, but it could be changed based on future research, congressional reaction or other developments…

The Census Bureau innovations are driven by the same forces afflicting all organizations that do survey research. People are increasingly reluctant to answer surveys, and the cost of collecting their data is rising. From 1970 to 2010, the bureau’s cost to count each household quintupled, to $98 per household in 2010 dollars, according to the GAO. The Census Bureau estimates that its innovations would save $5.2 billion compared with repeating the 2010 census design, so the 2020 census would cost a total of $12.5 billion, close to 2010’s $12.3 billion price tag (both in projected 2020 dollars)…

The only households receiving paper forms under the bureau’s plan would be those in neighborhoods with low internet usage and large older-adult populations, as well as those that do not respond online.

To maximize online participation, the Census Bureau is promoting the idea that answering the census is quick and easy. The 2010 census was advertised as “10 questions, 10 minutes.” In 2020, bureau officials will encourage Americans to respond anytime and anywhere – for example, on a mobile device while watching TV or waiting for a bus. Respondents wouldn’t even need their unique security codes at hand, just their addresses and personal data. The bureau would then match most addresses to valid security codes while the respondent is online and match the rest later, though it has left the door open to restrict use of this option or require follow-up contact with a census taker if concerns of fraud arise.

Perhaps the marketing slogan could be: “Do the Census online to save your own taxpayer dollars!”

It will be interesting to see how this plays out. I’m sure there will be plenty of tests to (1) make sure the people responding are matched correctly to their address (and that fraud can’t be committed); (2) the data collected is as accurate as going door to door and mailing out forms; and (3) the technological infrastructure is there to handle all the traffic. Even after going digital, the costs will be high and I’m guessing more people will ask why all the expense is necessary. Internet response rates to surveys are notoriously low so it may take a lot of marketing and reminders to get a significant percentage of online respondents.

But, if the Census Bureau can pull this off, it could represent a significant change for the Census as well as other survey organizations.

An overhead projector in the front window

Posted on by

As I was walking near campus recently, I came across a curious sight: the front window of a home filled with an overhead projector. It was facing inward, not working as an old-fashioned Christmas projector for the yard. I have never seen such a scene.

Why was the projector in the window? My first guess is that the owner is a teacher or educator of some kind. Indeed, it wasn’t too long ago that these devices were used in numerous classrooms at all levels. From my elementary through college years, instructors frequently used them. While they were being phased out while I was in college, some of the older faculty still used them regularly. (Indeed, I recently showed a class a YouTube clip of physicist Geoffrey West making a presentation about cities at the Santa Fe Institute with the help of an overhead projector.) Even early in graduate school, I remember hearing advice that a presenter could have overheads as a backup should a Powerpoint fail to load. But, you would be hard-pressed to find one in a classroom on my campus today (though they and the film projectors only disappeared in the last few years). I have no idea what happened to them.

The overhead projector preceded bulky TVs on the way to the landfill – if you can find people willing to take them – and perhaps they will a return as a retro decorative item…

Using smartphones to collect important economic data

Posted on by

Virginia Postrel describes a new app used in a number of countries to gather economic data on the ground:

Founded in 2012, the San Francisco-based startup Premise began by looking for a way to supplement official price indices with a quick-turnaround measure of inflation and relative currency values. It needed “a scalable, cost-effective way to collect a lot of price data,” chief executive David Soloff said in an interview. The answer was an Android app and more than 30,000 smart-phone-wielding contractors in 32 countries.

The contractors, who are paid by the usable photo and average about $100 a month, take pictures aimed at answering specific economic questions: How do the prices in government-run stores compare to those in private shops? Which brands of cigarette packages in which locations carry the required tax stamp? How many houses are hooked into power lines? What’s happening to food prices? Whatever the question, the data needed to answer it must be something a camera can capture…

The result is a collection of price indices updated much more frequently and with less time lag — although also fewer indicative items — than monthly government statistics. For Bloomberg terminal subscribers, Premise tracks food and beverage prices in the U.S., China, India, Brazil and Argentina, using indices mirroring government statistics. It gets new information daily; Bloomberg publishes new data twice a week. Premise tracks a similar index in Nigeria for Standard Chartered bank, which has made the aggregate data public. (Premise clients can drill down to see differences across products, types of retailers, or regions.) While more volatile than official statistics, the figures generally anticipate them, serving as an early-warning system for economic trends…

Premise has government clients, and it carefully positions its work as a complement to official statistics, as well as to the academic Billion Prices Project, which scrapes massive amounts of price data from online sources but can’t say what cooking oil sells for in a corner shop. Make no mistake, however: Its methods also provide valuable competition to the official data. The point, after all, is to find out what’s actually happening, not what government reports will say in a few weeks.

This is an innovative way to get data more quickly. It would be interesting to see how reliable this data is. Now it remains to be seen how markets, governments, and others will use more up-to-date information.

More broadly, smartphones could be used to collect all sorts of data. See previous posts on using the microphone and the use of additional apps such as Twitter and Waze.

Facebook wants global guidelines but has local standards

Posted on by

A recent addition to Facebook’s standards in Spain highlights a larger issue for the company: how to have consistent guidelines around the world while remaining respectful or relevant in local contexts.

For Facebook and other platforms like it, incidents such as the bullfighting kerfuffle betray a larger, existential difficulty: How can you possibly impose a single moral framework on a vast and varying patchwork of global communities?

If you ask Facebook this question, the social-media behemoth will deny doing any such thing. Facebook says its community standards are inert, universal, agnostic to place and time. The site doesn’t advance any worldview, it claims, besides the non-controversial opinion that people should “connect” online…

Facebook has modified its standards several times in response to pressure from advocacy groups – although the site has deliberately obscured those edits, and the process by which Facebook determines its guidelines remains stubbornly obtuse. On top of that, at least some of the low-level contract workers who enforce Facebook’s rules are embedded in the region – or at least the time zone – whose content they moderate. The social network staffs its moderation team in 24 languages, 24 hours a day…

And yet, observers remain deeply skeptical of Facebook’s claims that it is somehow value-neutral or globally inclusive, or that its guiding principles are solely “respect” and “safety.” There’s no doubt, said Tarleton Gillespie, a principal researcher at Microsoft Research, New England, that the company advances a specific moral framework – one that is less of the world than of the United States, and less of the United States than of Silicon Valley.

I like the shift in this discussion from free speech issues (mentioned later in the article) to issues of a particular moral framework that corporations have and promote. Some might argue that simply by being a corporation there is a very clear framework: Facebook needs to make money. How exactly can the company claim to be truly about connection when there is an overriding concern? On the other hand, various companies across industries have had to wrestle with this issue: when a company expands into additional culture, how do they balance the existing moral framework with new frameworks? Customers are at stake but so are basic concerns of dealing with people on their own terms and respecting other approaches to the world.

But, with a global capitalistic system where Facebook play a prominent role (in terms of rapid growth, connecting people, and market value), can it truly be “neutral”? Like many other behemoth companies (think McDonald’s or Walmart), it will certainly encounter its share of dissenters in the years to come.
