Marriage equality maps

The US Supreme Court declined to review seven same-sex marriage decisions today. The StatsChat-relevant aspect is the flurry of maps this prompted:

I think the New York Times (via Twitter) is my favorite version: the square statebins use geography just as an index to make states easier to find, and (in contrast to the last statebins I linked to) they’ve moved Alaska to the right place

Interactive election results map

The Herald has an interactive election-results map, which will show results for each polling place as they come in, together with demographic information about each electorate.  At the moment it’s showing the 2011 election data, and the displays are still being refined — but the Herald has started promoting it, so I figure it’s safe for me to link as well.

Mashblock is also developing an election site. At the moment they have enrolment data by age. Half the people under 35 in Auckland Central seem to be unenrolled,which is a bit scary. Presumably some of them are students enrolled at home, and some haven’t been in NZ long enough to enrol, but still.

Some non-citizens probably don’t know that they are eligible — I almost missed out last time. So, if you know someone who is a permanent resident and has lived in New Zealand for a year, you might just ask if they know about the eligibility rules. Tomorrow is the last day.

Health/nutrition claims: baby and bathwater

Australia and New Zealand are introducing new food labelling legislation that will reduce the scope for bogus health and nutrition claims (the only bogus claims allowed will be the ones that slipped into the official code).  This is a Good Thing, as I have said in the past.

The legislation also says you can’t make health claims about booze. This is probably a Good Thing, although I don’t see why calorie/carbohydrate claims shouldn’t be allowed.  However, there’s a serious bug in the standards: one of the claims that’s specifically disallowed for alcoholic beverages is “gluten-free.”

It’s true that “gluten-free” has become a trendy bogus nutrition claim, but it’s also vital health information for some people, particularly those with coeliac disease. In that context, “gluten-free” is more like an allergen warning (“May contain nuts”) than a nutrition warning.  In fact, if you look at the section on “Mandatory Warning and Advisory Statements and Declarations”, Clause 4 includes

Cereals containing gluten and their products, namely, wheat, rye, barley, oats and spelt and their hybridised strains other than where these substances are present in beer and spirits standardised in Standards 2.7.2 and 2.7.5 respectively

along with peanuts, soybeans, eggs, milk, etc.  That is, declaring the presence of gluten is mandatory except in beer, where it is the only one of the Clause 4 mandatory warnings that becomes forbidden.  Banning gluten-free labelling on beer is deliberate and planned, it didn’t just fall between the cracks.

Since this is a trans-Tasman law, it’s going to be a pain to revise.  There seems to be one possible loophole. In the Nutrition/Health claims standards, there is provision for endorsements by independent endorsing bodies. These are exempted from most of the health/nutrition regulations: as the Explanatory Text says:

Endorsements are exempt from the other requirements of the Standard (except clause 7), to allow for endorsement programs which use the criteria set by the endorsing body.

It appears (though I may have missed something, and I’m not a lawyer) that Coeliac New Zealand could still endorse gluten-free beers, even though the brewers couldn’t make the same claims themselves.

[Further update: MPI contacted Keruru Brewery and say they are now working on a solution for gluten-free beer.]

[update: I heard about this on Twitter, but the blog post that kicked off Twitter is here]

Big Data social context

From Cathy O’Neil: Ignore data, focus on power (and, well, most of the stuff on her blog)

From danah boyd and Kate Crawford: Critical Questions for Big Data

Will large-scale search data help us create better tools, services, and public goods? Or will it usher in a new wave of privacy incursions and invasive marketing? Will data ana- lytics help us understand online communities and political movements? Or will it be used to track protesters and suppress speech? Will it transform how we study human communication and culture, or narrow the palette of research options and alter what ‘research’ means?

When not to map

Maps are good because they take advantage of all the previous maps we’ve seen to provide background familiarity.  On the other hand, they use up both the available spatial dimensions before you’ve actually got any data, so you need to encode the information some other way. Colour is the obvious choice, but colour is much more limited than people appreciate.

Kieran Healy tweetedIt’s not like there’s a simple, tradeoff-free solution, but this is not a good map.”

And he’s right; it isn’t. There are too many categories, and some of them are ordered but not all of them, so colour isn’t enough. Even if you’re going to try, these aren’t the right colours: for example, orange should be between yellow and red.  About the most you could do clearly with a single map is the three-way split: Yes, same-sex couples can just roll up to the registry;  No, not this week; or It’s Complicated.

Jacob Harris pointed to an article at Source, describing the design of graphics for a story about marijuana legalisation. It does much better

They link to the classic piece “When maps shouldn’t be maps” by Matthew Ericson, which I’ve linked before. They also have a whole collection of articles on better maps, though it’s fairly programming-oriented.

White House report: ‘Big Data’

There’s a new report “Big Data: Seizing Opportunities, Preserving Values” from the Office of the President (of the USA).  Here’s part of the conclusion (there are detailed recommendations as well)

Big data tools offer astonishing and powerful opportunities to unlock previously inaccessible insights from new and existing data sets. Big data can fuel developments and discoveries in health care and education, in agriculture and energy use, and in how businesses organize their supply chains and monitor their equipment. Big data holds the potential to streamline the provision of public services, increase the efficient use of taxpayer dollars at every level of government, and substantially strengthen national security. The promise of big data requires government data be viewed as a national resource and be responsibly made available to those who can derive social value from it. It also presents the opportunity to shape the next generation of computational tools and technologies that will in turn drive further innovation.

Big data also introduces many quandaries. By their very nature, many of the sensor technologies deployed on our phones and in our homes, offices, and on lampposts and rooftops across our cities are collecting more and more information. Continuing advances in analytics provide incentives to collect as much data as possible not only for today’s uses but also for potential later uses. Technologically speaking, this is driving data collection to become functionally ubiquitous and permanent, allowing the digital traces we leave behind to be collected, analyzed, and assembled to reveal a surprising number of things about ourselves and our lives. These developments challenge longstanding notions of privacy and raise questions about the “notice and consent” framework, by which a user gives initial permission for their data to be collected. But these trends need not prevent creating ways for people to participate in the treatment and management of their information.

You can also read comments on the report by danah boyd, and the conference report and videos from her conference’The Social, Cultural & Ethical Dimensions of “Big Data”‘ are now online.

Big Data & privacy presentation

If you have time, there’s an interesting event that will be streamed from New York University this (NZ) morning (10:30am today NZ time, 5:30pm yesterday NY time)

..the Data & Society Research Institute, the White House Office of Science and Technology Policy, and New York University’s Information Law Institute will be co-hosting a public event entitled The Social, Cultural, & Ethical Dimensions of “Big Data.” The purpose of this event is to convene key stakeholders and thought leaders from across academia, government, industry, and civil society to examine the social, cultural, and ethical implications of “big data,” with an eye to both the challenges and opportunities presented by the phenomenon.

The event is being organised by danah boyd, who we’ve mentioned a few times and whose new book I plan to write about soon.

Should recreational genotyping be illegal?

The US Food and Drug Administration has sent a letter to 23andme, one of the companies that will genotype you and provide lots of information from the sample, telling them to stop. It’s a tricky situation.

This product is a device within the meaning of section 201(h) of the FD&C Act, 21 U.S.C. 321(h), because it is intended for use in the diagnosis of disease or other conditions or in the cure, mitigation, treatment, or prevention of disease, or is intended to affect the structure or function of the body. For example, your company’s website at www.23andme.com/health  (most recently viewed on November 6, 2013) markets the PGS for providing “health reports on 254 diseases and conditions,” including categories such as “carrier status,” “health risks,” and “drug response,” and specifically as a “first step in prevention” that enables users to “take steps toward mitigating serious diseases” such as diabetes, coronary heart disease, and breast cancer. Most of the intended uses for PGS listed on your website, a list that has grown over time, are medical device uses under section 201(h) of the FD&C Act. Most of these uses have not been classified and thus require premarket approval or de novo classification, as FDA has explained to you on numerous occasions.

On the one hand, I can’t see any valid social interest in stopping people from knowing their genotypes if they want to. On the other hand, the FDA has a point about marketing.

They raise two isssues.  The first is that 23andme make lots of (fairly weakly supported) claims about the usefulness of the results in disease prevention. The second is that some of the genotype information is actually clinically relevant and that they have not demonstrated sufficient accuracy in their results. The first issue is essentially a misleading advertising problem; the second is a quality assurance problem.

There are two things that can go wrong with the clinically useful results. The first is simple error: the genotype assay could give the wrong result, or you could be given results from someone else’s sample. This should be low probability, but it’s important to know how low — 1 in a 1000 would definitely be too high.

The second issue is interpretation. Suppose you have a lot of family members with breast cancer, and you suspect a BRCA1 mutation is responsible. You might be relieved if you test negative, and think your risk isn’t especially high, but that’s only a reliable conclusion if your family’s cancer risk was actually due to a BRCA1 mutation, not to some other genetic risk factor.

 

Update: I should probably note that 23andme could fix what I think are the actual problems, but this wouldn’t necessarily satisify the FDA.  The FDA aren’t currently being unreasonable oppressive Luddite statist bureaucrats, but they’re probably happy to be to if that’s the option on offer.

Blood alcohol change report

The detailed Ministry of Transport paper on changing the legal blood alcohol limit is now available.  There’s a story in Stuff, which is, if anything, unduly critical (an interesting change). It doesn’t mention the cost-benefit analysis, and implies a fines grab

Transport officials calculate nearly 20,000 people will be caught by the lower drink-driving limit – earning the Government $5 million extra in fines. 

which is a bit misleading since the report (paragraph 93) actually estimates a net increase in costs to the justice system of about $2 million in the first year and about half a million in subsequent years, ie, the fines don’t cover the costs of enforcing the change.

Basically, whether the change is a benefit or not depends on how much inconvenience and risk is caused to the average driver, the only major component that isn’t taken into account in the calculations.  If this is worth only 50c/month or so, the policy makes sense. If it’s worth a few dollars a month, not.

On the other hand, the policy is popular, and since most people should have a reasonable appreciation for how the change will affect them personally, that’s a more persuasive argument than it would ordinarily be.

A third of young Americans have been arrested

Via Keith Humphreys, being arrested is a very common experience for young people in America: using the National Longitudinal Survey of Youth, Richard Braeme and colleagues found

By age 18, the in-sample cumulative arrest prevalence rate lies between 15.9% and 26.8%; at age 23, it lies between 25.3% and 41.4%. These bounds make no assumptions at all about missing cases. If we assume that the missing cases are at least as likely to have been arrested as the observed cases, the in-sample age-23 prevalence rate must lie between 30.2% and 41.4%. The greatest growth in the cumulative prevalence of arrest occurs during late adolescence and the period of early or emerging adulthood
