A more important metric for Facebook is the same one that advertisers need to be looking at before they consider the social network for marketing efforts. How many of those accounts are active and real? It’s less of an issue for Facebook than it is for Twitter but all of the talk of total number of accounts in a social network is starting to sound like TV’s old mantra of how many households they reach. It’s an empty number that anyone who is doing even a little thinking will see as hype and not truly important.

there were suggestions of doom for Facebook and the concern that growth had stopped unless they get into China

The possibility of burn out on the service is considered as well

a 2007 Journal of Political Economy study found that most downloaders would not buy that content, even if they couldn't share it. "Downloads have an effect on sales that is statistically indistinguishable from zero," the authors flatly concluded then. "Our estimates are inconsistent with claims that file sharing is the primary reason for the decline in music sales during our study period."

But a later 2010 meta-study by the same authors concluded that piracy did, in fact, account for a bit of the decline in music sales—around 20 percent. The other 80 percent could be chalked up to the sale of digital singles rather than whole albums and the rise of other media options like video games.

"Downward pressure on leisure expenditure is likely to continue to increase due to rising costs of living and unemployment and drastic rises in the costs of (public) services," says the report. Having less money for entertainment has played a huge role in the decline of items like CDs. A 2004 US Consumer Expenditure Survey showed that even spending on CDs by people who had no computer (and were therefore unlikely to download and use BitTorrent) dropped by over 40 percent from 1999 through 2004. "Household budgets for entertainment are relatively inelastic as competition for spending on culture and entertainment increases and there are shifts in household expenditure as well," the LSE study notes.

Sir Tim Berners-Lee told the BBC that legislation may be needed if self-regulation failed. He has been asked by the UK government to negotiate an agreement on an open internet between service providers and content firms like the BBC and Skype. Sir Tim would prefer self-regulation by the internet industry, but progress has been slow. "If it fails the government has to be absolutely ready to legislate," he said. "It may be that the openness of the internet, we should just put into law." Net neutrality, the idea that all traffic on the internet should be treated equally, has been a controversial issue in the United States and is now moving up the political agenda in the UK.

Internet Service Providers have claimed that they need to be able to control the growing traffic online, and content creators fear that the result could be a two-speed internet. Sir Tim said that he understands the need for traffic management but any move to discriminate between different content businesses would be a step too far.

"What you lose when you do that is you lose the open market," he said. "What the companies gain is that they get complete control of you." But Professor William Dutton of the Oxford Internet Institute warned that enshrining net neutrality in law had its dangers. "Once you allow the state in, you open the door to all sorts of regulation of the internet controls on content creation," he said.

The discovery that Android devices - which are quickly becoming the best-selling products in the smartphone space - also collect location data indicates how essential such information has become to their effective operation. "Location services", which can help place a user on a map, are increasingly seen as important for providing enhanced services including advertising - which forms the basis of Google's business.

Smartphones running Google's Android software collect data about the user's movements in almost exactly the same way as the iPhone, according to an examination of files they contain. The discovery, made by a Swedish researcher, comes as the Democratic senator Al Franken has written to Apple's chief executive Steve Jobs demanding to know why iPhones keep a secret file recording the location of their users as they move around, as the Guardian revealed this week.

Magnus Eriksson, a Swedish programmer, has shown that Android phones – now the bestselling smartphones – do the same, though for a shorter period. According to files discovered by Android devices keep a record of the locations and unique IDs of the last 50 mobile masts that it has communicated with, and the last 200 Wi-Fi networks that it has "seen". These are overwritten, oldest first, when the relevant list is full. It is not yet known whether the lists are sent to Google. That differs from Apple, where the data is stored for up to a year.

there is a deeper issue here that spans political parties across nations:  a lack of recognition among policy makers of their dependence on experts in making wise decisions.  Experts do not, of course, determine how policy decisions ought to be made but they do add considerable value to wise decision making.

The deeper issue at work here is an open secret in the practice of democracy, and that is the fact that our elected leaders are chosen from among us, the people.  As such, politicians tend to reflect the views of the general public on many subjects - not just those subjects governed solely by political passions, but also those that are traditionally the province of experts.  Elected officials are not just a lot like us, they are us.

Agent Anything is part matching and part auction; it sets up “agents” with “missions,” with the price for each task set by the buyer. The missions range from delivering food to assembling IKEA furniture to doing manual labor like data entry. The other night, my roommate had some Ben & Jerry’s delivered at his right price. He even gave a tip.

Open government cannot succeed through technology only.  Open data, ideation platforms, cloud solutions, and social media are great tools but when they are used to deliver government services using existing models they can only deliver partial value, value which can not be measured and value that is unclear to anyone but the technology practitioners that are delivering the services.

It is this thinking that has led a small group of us to launch a new Group on Govloop called Culture Change and Open Government.  Bill Brantley wrote a great overview of the group which notes that “The purpose of this group is to create an international community of practice devoted to discussing how to use cultural change to bring about open government and to use this site to plan and stage unconferences devoted to cultural change“

“Open government is a citizen-centric philosophy and strategy that believes the best results are usually driven by partnerships between citizens and government, at all levels. It is focused entirely on achieving goals through increased efficiency, better management, information transparency, and citizen engagement and most often leverages newer technologies to achieve the desired outcomes. This is bringing business approaches, business technologies, to government“.

Yesterday, the Office of Research Integrity (ORI), part of the US Department of Health and Human Services, issued a finding of research misconduct for Vipul Bhrigu, a former postdoctoral fellow at the University of Michigan, debarring him for three years from involvement in US federally funded research and from serving as an advisor to the US Public Health Service. The federal register carried the note today. Bhrigu, now in India, was caught on videotape sabotaging the experiments of a graduate student in his lab at the univeristy last year. And today, Nature releases exclusive surveillance tapes, obtained through the Freedom of Information Act in Michigan.

Video: This video, obtained by Nature via the Freedom of Information Act, shows Vipul Bhrigu carrying a spray bottle full of ethanol into the refrigerator where Heather Ames had stored her cell culture media and contaminating her reagents.

THINK income inequality growth is primarily an American phenomenon?  Think again:American society is more unequal than those in most other OECD countries, and growth in inequality there has been relatively large. But with very few exceptions, the rich have done better over the past 30 years, even in highly egalitarian places like Scandinavia.

Over the past decades, OECD countries have undergone significant structural changes resulting from their closer integration into a global economy and rapid technological progress. These changes have brought higher rewards for high-skilled workers and thus affected the way earnings from work are distributed. The skills gap in earnings reflects several factors. First, a rapid rise in trade and financial markets integration has generated a relative shift in labour demand in favour of high-skilled workers at the expense of low-skilled labour. Second, technical progress has shifted production technologies in both industries and services in favour of skilled labour...Finally, during the past two decades most OECD countries carried out regulatory reforms to strengthen competition in the markets for goods and services and associated reforms that aimed at making labour markets more adaptable. For instance, anti-competitive product-market regulations were reduced significantly in all countries. Employment protection legislation for workers with temporary contracts also became more lenient in many countries. Minimum wages, relative to average wages, have also declined in a number of countries since the 1980s. Wage-setting mechanisms have also changed; the share of union members among workers has fallen across most countries, although the coverage of collective bargaining has generally remained rather stable over time. In a number of countries, unemployment benefit replacement rates fell, and in an attempt to promote employment among low-skilled workers, taxes on labour for low-income workers were also reduced.

It's tempting to look at this list of regulatory changes and argue that it was these rule changes which facilitated growth in inequality. That may be true to some extent, but the unverisality of the reform experience makes me think it's at least as likely that underlying trends (like globalisation and technological change) made the prevailing rules unsustainable.

The study aims to calculate the costs incurred as a consequence of crime, which includes "monetary loss in traditional terms" and "monetising the loss of life and trauma suffered by victims".Costs of crime prevention and enforcement will also be tallied. The study seeks to find out costs borne by private entities - such as security expenditure and insurance - as well as costs borne by public bodies such as proactive police patrols in anticipation of crime.The police also intend to calculate the costs incurred in response to crime - investigating cases, apprehending suspects as well as the costs expended by the State in prosecuting, convicting and incarcerating suspects.

While costs of crime prevention - such as installing alarm systems - and the State's response to crime could be measured, sociologist Paulin Straughan felt it might be "impossible" to measure the social costs of a spate of violence on a community. Social isolation and mistrust from these crimes would impact social capital on a community which would be difficult to estimate, she argued.However, the former Nominated Member of Parliament felt calculating the cost of crime would serve as "a reality check" for any society.

"We live in a world that is driven by economics," Associate Professor Straughan said. "We can't understand or appreciate unless it is documented in dollars and cents. So, this is one way of documenting it (crime) in dollars and cents to show you that every burglary cost you this (amount) … and highlight the importance of crime prevention."

All of this Internet activity is but the tip of the iceberg of a new and growing global human-tissue economy. Indeed, the World Health Organization (WHO) has estimated that about 10% of organ transplants around the world stem from purely commercial transactions.

Trade in organs follows a clear, geographically linked pattern: people from rich countries buy the organs, and people in poor countries sell them. In my research on organ trafficking, I have entered some of these shadow markets, where body parts from the poor, war victims, and prisoners are commodities, bought or stolen for transplant into affluent ill people.

Organ trafficking depends on several factors. One is people in distress. They are economically or socially disadvantaged, or live in war-torn societies with prevalent crime and a thriving black market. On the demand side are people who are in danger of dying unless they receive an organ transplant. Additionally, there are organ brokers who arrange the deals between sellers and buyers.

make it easier for users to define their relationships with other users—such as by labeling those who are real friends, as opposed to those who are just "fans." And there will be special services, like "personal assistants," to help the site's most influential users with technical questions.

Social-networking sites have taken off in much of the world, with users across the globe becoming increasingly interconnected. But unlike many other markets, China—which has more than 450 million Internet users, more than any other country—isn't dominated by big U.S. companies like Twitter Inc. and Facebook Inc. In fact, China's government blocks access to those two sites for users inside the country. MySpace China, an affiliate of the U.S. social-networking site that is partly owned by News Corp., has struggled. News Corp. also owns The Wall Street Journal.

a host of domestic Chinese companies are competing to fill the space. RenRen Inc., which runs one of the biggest Facebook-like sites in China, raised $743 million in a U.S. initial public offering in May that it is using to beef up its offerings. Rival Kaixin001, held by Happy Networks Ltd., also operates a social-networking site similar to Facebook. Chinese search giant Baidu Inc. is trying to turn its popular message board, Baidu Tieba, or Postbar, into more of a social network, and had its own microblogging service, Baidu Shuoba, or Baidu Talk, which failed to gain traction against Sina and now has been suspended. Sohu.com Inc. and NetEase.com Inc. offer microblogs.

The inquiry will examine the heart of Google's search-advertising business, and the source of most of Google's revenue. Google accounts for around two-thirds of internet searches in the US (and close to 90% in the UK) and according to critics unfairly uses that dominance to favour its own growing network of services.Last November, the European commission opened its own formal investigation into allegations that Google discriminated against competing services in its search results and prevented some websites from using ads by Google competitors.

Legal experts said the investigation could be similar in scale to the massive antitrust probe of Microsoft, which started in 1991 and ended in a settlement a decade later. Professor Joshua Wright of George Mason Law School said: "The investigation will be of a comparable scale to that of Microsoft."But he said the chances of Google being found guilty of antitrust behaviour, as Microsoft was, were far smaller. Wright said for the US to bring a successful case against Google, it would have to prove the company was harming consumers. "As an outsider I would say that obstacle is far higher for them today with Google than it was back then with Microsoft," he said.

He said Google faced a higher risk in the EU case but that in either case the investigations were likely to have a profound impact on the firm."Even if the charges are ultimately bogus, they will occupy many, many hours of managements time and attention," he said.The FTC's investigations are likely to widen to other companies as official requests for information about their dealings with Google.The company has long denied any anticompetitive behaviour, arguing that users can easily click on other choices on the web.

The USPSTF recently issued an even sharper warning about the prostate-specific antigen test for prostate cancer, after concluding that the test’s harms outweigh its benefits. Chest X-rays for lung cancer and Pap tests for cervical cancer have received similar, albeit less definitive, criticism.CommentsView/Create comment on this paragraphThe next step in the reevaluation of cancer screening was taken last year, when researchers at the Dartmouth Institute for Health Policy announced that the costs of screening for breast cancer were often minimized, and that the benefits were much exaggerated. Indeed, even a mammogram (almost 40 million are given annually in the US) that detects a cancer does not necessarily save a life.CommentsView/Create comment on this paragraphThe Dartmouth researchers found that, of the estimated 138,000 breast cancers detected annually in the US, the test did not help 120,000-134,000 of the afflicted women. The cancers either were growing so slowly that they did not pose a problem, or they would have been treated successfully if discovered clinically later (or they were so aggressive that little could be done).
