If I call you, will you call back? The study of reciprocity between mobile phone users reveals surprising insights about the flow of information in society.

What do your mobile phone habits say about you? Probably more than you might imagine.

At least, that’s the suggestion from Lauri Kovanen and pals at the Aalto University School of Science and Technology, Finland. These guys have studied the 350 million calls made by 5.3 million customers over an unnamed mobile phone network during a period of 18 weeks. The primary question they ask is whether mobile phone calls are mutually reciprocated: in other words, does somebody who calls another individual receive in return as many calls as he or she makes, a phenomenon known as reciprocity.

Mobile phone calls are a particularly good way to study reciprocity because they are directed in a way that sms messages and email are not. In a mobile phone call, the caller initiates the conversation and then both parties invest a certain amount of time in the event. But afterwards there is usually no immediate reason for the recipient to call back. So it’s clear who initiated the event.

But SMS messages or e-mails are entirely different: here a conversation usually means sending a sequence of reciprocated messages and this makes it much more difficult to study reciprocity by simply counting the number of messages.

The long-term effects of short-term emotions

The heat of the moment is a powerful, dangerous thing. We all know this. If we’re happy, we may be overly generous. Maybe we leave a big tip, or buy a boat. If we’re irritated, we may snap. Maybe we rifle off that nasty e-mail to the boss, or punch someone. And for that fleeting second, we feel great. But the regret—and the consequences of that decision—may last years, a whole career, or even a lifetime.

At least the regret will serve us well, right? Lesson learned—maybe.

Maybe not. My friend Eduardo Andrade and I wondered if emotions could influence how people make decisions even after the heat or anxiety or exhilaration wears off. We suspected they could. As research going back to Festinger’s cognitive dissonance theory suggests, the problem with emotional decisions is that our actions loom larger than the conditions under which the decisions were made. When we confront a situation, our mind looks for a precedent among past actions without regard to whether a decision was made in emotional or unemotional circumstances. Which means we end up repeating our mistakes, even after we’ve cooled off.

Who are the best spreaders of information in a social network? The answer may surprise you.

The study of social networks has thrown up more than a few surprises over the years. It’s easy to imagine that because the links that form between various individuals in a society are not governed by any overarching rules, they must have a random structure. So the discovery in the 1980s that social networks are very different came as something of a surprise. In a social network, most nodes are not linked to each other but can easily be reached by a small number of steps. This is the so-called small worlds network.

Today, there’s another surprise in store for network connoisseurs courtesy of Maksim Kitsak at Boston University and various buddies. One of the important observations from these networks is that certain individuals are much better connected than others. These so-called hubs ought to play a correspondingly greater role in the way information and viruses spread through society.

In fact, no small effort has gone into identifying these individuals and exploiting them to either spread information more effectively or prevent them from spreading disease.

The importance of hubs may have been overstated, say Kitsak and pals. “In contrast to common belief, the most influential spreaders in a social network do not correspond to the best connected people or to the most central people,” they say.

Imagine that your stockbroker - or the friend who’s always giving you stock tips - called and told you he had come up with a new investment strategy. Price-to-earnings ratios, debt levels, management, competition, what the company makes, and how well it makes it, all those considerations go out the window. The new strategy is this: Invest in companies with names that are very easy to pronounce.

This would probably not strike you as a great idea. But, if recent research is to be believed, it might just be brilliant.

One of the hottest topics in psychology today is something called “cognitive fluency.” Cognitive fluency is simply a measure of how easy it is to think about something, and it turns out that people prefer things that are easy to think about to those that are hard. On the face of it, it’s a rather intuitive idea. But psychologists are only beginning to uncover the surprising extent to which fluency guides our thinking, and in situations where we have no idea it is at work.

“How we process information is related not just to our brains but to our entire body,” said Nils B. Jostmann of the University of Amsterdam. “We use every system available to us to come to a conclusion and make sense of what’s going on.”

Research in embodied cognition has revealed that the body takes language to heart and can be awfully literal-minded.

Why are people so blissfully ignorant of certain aspects of their personalities?

Take an everyday example: there are some infuriating people who are always late for appointments. A few of these people explain it by saying they are ‘laid-back’, while others seem unaware that they’re always late.

For laid-back people, their lateness is a part of their personality, they are aware of it and presumably not worried about appearing unconscientious. For the unaware it’s almost as if they don’t realise they’re always late. How is that possible?

It’s probably because they’ve never noticed or paid attention to the fact that they are always late so they never learn to think of themselves as lacking conscientiousness. Or so suggests a psychological theory describing how we think about ourselves called self-schema theory.

This theory says that we have developed ’schemas’, like internal maps of our personalities, which we use to understand and explain our current and future behaviour to ourselves, e.g. I’m always on time for meetings so I’m a conscientious person.

However schema theory also suggests that these maps have uncharted areas, leaving people with certain blind spots in their self-knowledge.

YouMe: Control Real People In Real Time

An unusual new service called YouMe is being touted as the next generation of gaming, and a new way of sourcing help. The service will let users (”Yous”) control real people (”Mes”) in real time. Yous give instructions to the Mes via bluetooth headset or text message, and the Mes escapades are captured by video camera and streamed live.  Almost anything is game as far as requests, barring illegal or sexual activity. YouMe is in private beta, and should launch later this year.

The patient was a 15-year-old girl employed in a local bar. She was admitted to hospital after a knife fight involving her, a former lover and a new boyfriend. Who stabbed whom was not quite clear but all three participants in the small war were admitted with knife injuries. (…)

Precisely 278 days later the patient was admitted again to hospital with acute, intermittent abdominal pain. Abdominal examination revealed a term pregnancy with a cephalic fetal presentation. The uterus was contracting regularly and the fetal heart was heard. Inspection of the vulva showed no vagina, only a shallow skin dimple was present below the external urethral meatus and between the labia minora. An emergency lower segment caesarean section was performed under spinal anaesthesia and a live male infant weighing 2800 g was born…

The patient was well aware of the fact that she had no vagina and she had started oral experiments after disappointing attempts at conventional intercourse. Just before she was stabbed in the abdomen she had practised fellatio with her new boyfriend and was caught in the act by her former lover. The fight with knives ensued. She had never had a period and there was no trace of lochia after the caesarean section. She had been worried about the increase in her abdominal size but could not believe she was pregnant

Chronic pain is associated with a loss of the normal capacity to know where your body is. Chronic pain is also associated with odd bodily feelings. To find out if people with chronic back pain had trouble ‘feeling’ their back, they were asked to draw on a piece of paper the outline of where they felt their back to be. This is a bit tricky to understand, but imagine you are surveying, in your head, how your body feels and then drawing its location. Anyway, you might have to read the paper to really get it. This is what we found: six out of six patients with low back pain, when they were trying to draw where they felt their back to be, said “I can’t find it” or “I’ve lost it”. When an independent investigator assessed sensory acuity on the back, sensory acuity was reduced in the same place the patient couldn’t feel properly. (…)

In short we think it demonstrates that chronic back pain is associated with distorted body image of the back.

What’s the matter, you too good for this ten dollars?

When does a potential crisis become an actual crisis, and how and why does it happen? Why did most everyone believe there were no problems in the US (or Japanese or European or British) economies in 2006? Yet now we are mired in a very difficult situation. “The subprime problem will be contained,” said now controversially confirmed Fed Chairman Bernanke, just months before the implosion and significant Fed intervention. I have just returned from Europe, and the discussion often turned to the potential of a crisis in the Eurozone if Greece defaults. Plus, we take a look at the very positive US GDP numbers released this morning. Are we finally back to the Old Normal? There’s just so much to talk about. (…)

Before we get into the main discussion point, let me briefly comment on today’s GDP numbers, which came in at an amazingly strong 5.7% growth rate. While that is stronger than I thought it would be (I said 4-5%), there are reasons to be cautious before we sound the “all clear” bell.

First, over 60% (3.7%) of the growth came from inventory rebuilding, as opposed to just 0.7% in the third quarter. If you examine the numbers, you find that inventories had dropped below sales, so a buildup was needed. Increasing inventories add to GDP, while, counterintuitively, sales from inventory decrease GDP. Businesses are just adjusting to the New Normal level of sales. I expect further inventory build-up in the next two quarters, although not at this level, and then we level off the latter half of the year.

While rebuilding inventories is a very good thing, that growth will only continue if sales grow. Otherwise inventories will find the level of the New Normal and stop growing. And if you look at consumer spending in the data, you find that it actually declined in the 4th quarter, both annually and from the previous quarter. “Domestic demand” declined from 2.3% in the third quarter to only 1.7% in the fourth quarter. Part of that is clearly the absence of “Cash for Clunkers,” but even so that is not a sign of economic strength.

Second, as my friend David Rosenberg pointed out, imports fell over the 4th quarter. Usually in a heavy inventory-rebuilding cycle, imports rise because a portion of the materials businesses need to build their own products comes from foreign sources. Thus the drop in imports is most unusual. Falling imports, which is a sign of economic retrenching, also increases the statistical GDP number.

Third, I have seen no analysis (yet) on the impact of the stimulus spending, but it was 90% of the growth in the third quarter, or a little less than 2%.

Fourth (and quoting David): “… if you believe the GDP data - remember, there are more revisions to come - then you de facto must be of the view that productivity growth is soaring at over a 6% annual rate. No doubt productivity is rising - just look at the never-ending slate of layoff announcements. But we came off a cycle with no technological advance and no capital deepening, so it is hard to believe that productivity at this time is growing at a pace that is four times the historical norm. Sorry, but we’re not buyers of that view. In the fourth quarter, aggregate private hours worked contracted at a 0.5% annual rate and what we can tell you is that such a decline in labor input has never before, scanning over 50 years of data, coincided with a GDP headline this good.

“Normally, GDP growth is 1.7% when hours worked is this weak, and that is exactly the trend that was depicted this week in the release of the Chicago Fed’s National Activity Index, which was widely ignored. On the flip side, when we have in the past seen GDP growth come in at or near a 5.7% annual rate, what is typical is that hours worked grows at a 3.7% rate. No matter how you slice it, the GDP number today represented not just a rare but an unprecedented event, and as such, we are willing to treat the report with an entire saltshaker - a few grains won’t do.”

Finally, remember that third-quarter GDP was revised downward by over 30%, from 3.5% to just 2.2% only 60 days later. (There is the first release, to be followed by revisions over the next two months.) The first release is based on a lot of estimates, otherwise known as guesswork. The fourth-quarter number is likely to be revised down as well.

Unemployment rose by several hundred thousand jobs in the fourth quarter, and if you look at some surveys, it approached 500,000. That is hardly consistent with a 5.7% growth rate. Further, sales taxes and income-tax receipts are still falling. As I said last year that it would be, this is a Statistical Recovery. When unemployment is rising, it is hard to talk of real recovery. Without the stimulus in the latter half of the year, growth would be much slower.

So should we, as Paul Krugman suggests, spend another trillion in stimulus if it helps growth? No, because, as I have written for a very long time, and will focus on in future weeks, increased deficits and rising debt-to-GDP is a long-term losing proposition. It simply puts off what will be a reckoning that will be even worse, with yet higher debt levels. You cannot borrow your way out of a debt crisis. (…)

Now, there are bullish voices telling us that things are headed back to normal. Mainstream forecasts for GDP growth this year are quite robust, north of 4% for the year, based on evidence from past recoveries. However, the underlying fundamentals of a banking crisis are far different from those of a typical business-cycle recession, as Reinhart and Rogoff’s work so clearly reveals. It typically takes years to work off excess leverage in a banking crisis, with unemployment often rising for 4 years running. We will look at the evidence in coming weeks.

When most people think about geography, they think about maps. Lots of maps. Maps with state capitals and national territories, maps showing mountains and rivers, forests and lakes, or maps showing population distributions and migration patterns. And indeed, that isn’t a wholly inaccurate idea of what the field is all about. It is true that modern geography and mapmaking were once inseparable. (…)

In our own time, another cartographic renaissance is taking place. In popular culture, free software applications like Google Earth and MapQuest have become almost indispensable parts of our everyday lives: we use online mapping applications to get directions to unfamiliar addresses and to virtually “explore” the globe with the aid of publicly available satellite imagery. Consumer-available GPS have made latitude and longitude coordinates a part of the cultural vernacular. (…)

Geography, then, is not just a method of inquiry, but necessarily entails the production of a space of inquiry. Geographers might study the production of space, but through that study, they’re also producing space. Put simply, geographers don’t just study geography, they create geographies. (…)

Experimental geography means practices that take on the production of space in a self-reflexive way, practices that recognize that cultural production and the production of space cannot be separated from each another, and that cultural and intellectual production is a spatial practice.

State Representative James Tokioka did some research and drafted a bill that prohibits catching, selling or even possessing walu in Hawaii.

“I talked [to] many people who sell fish, some of the hotel who [buys] fish, they are aware of it and they’re not buying it anymore,” said Rep. Tokioka.

Tokioka said people have shared their nightmares of severe diarrhea after consuming a large portion of the fish. The oily walu or Escolar contains a high-level of wax esters in its tissue that are beneficial to its deep-sea survival, but can be unkind to humans.
