Looking after and using data for public benefit
Heather Savory at the Office for National Statistics (UK): “Official Statistics are for the benefit of society and the economy and help Britain to make better decisions. They allow the formulation of better public policy and the effective measurement of those policies. They inform the direction of economic and commercial activities. They provide valuable information for analysts, researchers, public and voluntary bodies. They enable the public to hold
The ability to harness the power of data is critical in enabling official statistics to support the most important decisions facing the country.
Under the new powers in the Digital Economy Act , ONS can now gain access to new and different sources of data including ‘administrative’ data from government departments and commercial data. Alongside the availability of these new data sources ONS is experiencing a strong demand for ad hoc insights alongside our traditional statistics.
We need to deliver more, faster, finer-grained insights into the economy and society. We need to deliver high quality, trustworthy information, on a faster timescale, to help decision-making. We will increasingly develop innovative data analysis methods, for example using images to gain insight from the work we’ve recently announced on Urban Forests
I should explain here that our data is not held in one big linked database; we’re architecting our Data Access Platform so that data can be linked in different ways for different purposes. This is designed to preserve data confidentiality, so only the necessary subset of data is accessible by authorised people, for a certain purpose. To avoid compromising their effectiveness, we do not make public the specific details of the security measures we have in place, but our recently tightened security regime, which is independently assured by trusted external bodies, includes:
- physical measures to restrict who can access places where data is stored;
- protective measures for all data-related IT services;
- measures to restrict who can access systems and data held by ONS;
- controls to guard against staff or contractors misusing their legitimate access to data; including vetting to an appropriate level for the sensitivity of data to which they might have access.
One of the things I love about working in the public sector is that our work can be shared openly.
We live in a rapidly changing and developing digital world and we will continue to monitor and assess the data standards and security measures in place to ensure they remain strong and effective. So, as well as sharing this work openly to reassure all our data suppliers that we’re taking good care of their data, we’re also seeking feedback on our revised data policies.
The same data can provide different insights when viewed through different lenses or in different combinations. The more data is shared – with the appropriate safeguards of course – the more it has to give.
If you work with data, you’ll know that collaborating with others in this space is key and that we need to be able to share data more easily when it makes sense to do so. So, the second reason for sharing this work openly is that, if you’re in the technical space, we’d value your feedback on our approach and if you’re in the data space and would like to adopt the same approach, we’d love to support you with that – so that we can all share data more easily in the future….(More)
ONS’s revised policies on the use, management
New mathematical model can help save endangered species
The risk of extinction varies from species to species depending on how individuals in its populations reproduce and how long each animal survives. Understanding the dynamics of survival and reproduction can support management actions to improve a specie’s chances of surviving.
Mathematical and statistical models have become powerful tools to help explain these dynamics. However, the quality of the information we use to construct such models is crucial to improve our chances of accurately predicting the fate of populations in nature.
Colchero’s research focuses on mathematically recreating the population dynamics by better understanding the species’s demography. He works on constructing and exploring stochastic population models that predict how a certain population (for example an endangered species) will change over time.
These models include mathematical factors to describe how the species’ environment, survival rates and reproduction determine to the population’s size and growth. For practical reasons some assumptions are necessary.
Two commonly accepted assumptions are that survival and reproduction are constant with age, and that high survival in the species goes hand in hand with reproduction across all age groups within a species. Colchero challenged these assumptions by accounting for age-specific survival and reproduction, and for trade-offs between survival and reproduction. This is, that sometimes conditions that favor survival will be unfavorable for reproduction, and vice versa.
For his work Colchero used statistics, mathematical derivations, and computer simulations with data from wild populations of 24 species of vertebrates. The outcome was a significantly improved model that had more accurate predictions for a species’ population growth.
Despite the technical nature of Fernando’s work, this type of model can have very practical implications as they provide qualified explanations for the underlying reasons for the extinction. This can be used to take management actions and may help prevent
Data Was Supposed to Fix the U.S. Education System. Here’s Why It Hasn’t.
Simon Rodberg at Harvard Business School: “For too long, the American education system failed too many kids, including far too many poor kids and kids of color, without enough public notice or accountability. To combat this, leaders of all political persuasions championed the use of testing to measure progress and drive better results. Measurement has become so common that in school districts from coast to coast you can now find calendars marked “Data Days,” when teachers are expected to spend time not on teaching, but on analyzing data like end-of-year and mid-year exams, interim assessments, science and social studies and teacher-created and computer-adaptive tests, surveys, attendance and behavior notes. It’s been this way for more than 30 years, and it’s time to try a different approach.
The big numbers are necessary, but the more they proliferate, the less value they add. Data-based answers lead to further data-based questions, testing, and analysis; and the psychology of leaders and policymakers means that the hunt for data gets in the way of actual learning. The drive for data responded to a real problem in education, but bad thinking about testing and data use has made the data cure worse than the disease
The leadership decision at stake is how much data to collect. I’ve heard variations on “In God we trust; all others bring data” at any number of conferences and beginning-of-school-year speeches. But the mantra “we believe in data” is actually only shorthand for “we believe our actions should be informed by the best available data.” In education, that mostly means testing. In other fields, the kind of process is different, but the issue is the same. The key question is not, “will the data be useful?” (of course it can be) or, “will the data be interesting?” (Yes, again.) The proper question for leaders to ask is: will the data help us make better-enough decisions to be worth the cost of getting and using it? So far, the answer is “no.”
Nationwide data suggests that the growth of data-driven schooling hasn’t worked even by its own lights. Harvard professor Daniel Koretz says “The best estimate is that test-based accountability may have produced modest gains in elementary-school mathematics but no appreciable gains in either reading or high-school mathematics — even though reading and mathematics have been its primary focus.”
We wanted data to help us get past the problem of too many students learning too little, but it turns out that data is an insufficient, even misleading answer. It’s possible that all we’ve learned from our hyper-focus on data is that better instruction won’t come from more detailed information, but from changing what people do. That’s what data-driven reform is meant for, of course: convincing teachers of the need to change and
All of Us Research Program Expands Data Collection Efforts with Fitbit
NIH Press Release: “The All of Us Research Program has launched the Fitbit Bring-Your-Own-Device (BYOD) project. Now, in addition to providing health information through surveys, electronic health records, and biosamples, participants can choose to share data from their Fitbit accounts to help researchers make discoveries. The project is a key step for the program in integrating digital health technologies for data collection.
Digital health technologies, like mobile apps and wearable devices, can gather data outside of a hospital or clinic. This data includes information about physical activity, sleep, weight, heart rate, nutrition, and water intake, which can give researchers a more complete picture of participants’ health. The All of Us Research Program is now gathering this data in addition to surveys, electronic health record information, physical measurements, and blood and urine samples, working to make the All of Us resource one of the largest and most diverse data sets of its kind for health research.
“Collecting real-world, real-time data through digital technologies will become a fundamental part of the program,” said Eric Dishman, director of the All of Us Research Program. “This information, in combination with many other data types, will give us an unprecedented ability to better understand the impact of lifestyle and environment on health outcomes and, ultimately, develop better strategies for keeping people healthy in a very precise, individualized way.”…
All of Us is developing additional plans to incorporate digital health technologies. A second project with Fitbit is expected to launch later in the year. It will include providing devices to a limited number of All of Us participants who will be randomly invited to take part, to enable them to share wearable data with the program. And All of Us will add connections to other devices and apps in the future to further expand data collection efforts and engage participants in new ways….(More)”.
The Internet of Bodies: A Convenient—and, Yes, Creepy—New Platform for Data Discovery
David Horrigan at ALM: “In the Era of the Internet of Things, we’ve become (at least somewhat) comfortable with our refrigerators knowing more about us than we know about ourselves and our Apple watches transmitting our every movement. The Internet of Things has even made it into the courtroom in cases such as the hot tub saga of Amazon Echo’s Alexa in State v. Bates and an unfortunate wife’s Fitbit in State v.
But the Internet of Bodies?…
The Internet of Bodies refers to the legal and policy implications of using the human body as a technology platform,” said Northeastern University law professor Andrea Matwyshyn, who works also as co-director of Northeastern’s Center for Law, Innovation, and Creativity (CLIC).
“In brief, the Internet of Things (IoT) is moving onto and inside the human body, becoming the Internet of Bodies (IoB),” Matwyshyn added
The Internet of Bodies is not merely a theoretical discussion of what might happen in the future. It’s happening already.
Former U.S. Vice President Dick Cheney revealed in 2013 that his physicians ordered the wireless capabilities of his heart implant disabled out of concern for potential assassin hackers, and in 2017, the U.S. Food and Drug Administration recalled almost half a million pacemakers over security issues requiring a firmware update.
It’s not just former vice presidents and heart patients becoming part of the Internet of Bodies. Northeastern’s Matwyshyn notes that so-called “smart pills” with sensors can report back health data from your stomach to smartphones, and a self-tuning brain implant is being tested to treat Alzheimer’s and Parkinson’s.
So, what’s not to like?
Better with Bacon?
“We are attaching everything to the Internet whether we need to or not,” Matwyshyn said, calling it the “Better with Bacon” problem, noting that—as bacon has become a popular condiment in restaurants—chefs are putting it on everything from drinks to cupcakes.
“It’s great if you love bacon, but not if you’re a vegetarian or if you just don’t like bacon. It’s not a bonus,” Matwyshyn added.
Matwyshyn’s bacon analogy raises interesting questions: Do we really need to connect everything to the Internet? Do the data privacy and data protection risks outweigh the benefits?
The Northeastern Law professor divides these IoB devices into three generations: 1) “body external” devices, such as
Chip Party for Chipped Employees
A Wisconsin company, Three Square Market, made headlines in 2017—including an appearance on The Today Show—when the company microchipped its employees, not unlike what veterinarians do with the family pet. Not surprisingly, the company touted the benefits of implanting microchips under the skin of employees, including being able to wave one’s hand at a door instead of having to carry a badge or use a password….(More)”.
The Age of Surveillance Capitalism
Book by Shoshana Zuboff: “The challenges to humanity posed by the digital future, the first detailed examination of the unprecedented form of power called “surveillance capitalism,” and the quest by powerful corporations to predict and control our behavior.
Shoshana Zuboff’s interdisciplinary breadth and depth enable her to come to grips with the social, political, business, and technological meaning of the changes taking place in our time. We are at a critical juncture in the confrontation between the vast power of giant high-tech companies and government, the hidden economic logic of surveillance capitalism, and the propaganda of machine supremacy that threaten to shape and control human life. Will the brazen new methods of social engineering and behavior modification threaten individual autonomy and democratic rights and introduce extreme new forms of social inequality? Or will the promise of the digital age be one of individual empowerment and democratization?
The Age of Surveillance Capitalism is neither a hand-wringing narrative of danger and decline nor a digital fairy tale. Rather, it offers a deeply reasoned and evocative examination of the contests over the next chapter of capitalism that will decide the meaning of information civilization in the twenty-first century. The stark issue at hand is whether we will be the masters of information and machines or its slaves. …(More)”.

China will now officially try to extend its Great Firewall to blockchains
Mike Orcutt at Technology Review: “China’s crackdown on blockchain technology has taken another step: the country’s internet censorship agency has just approved new regulations aimed at blockchain companies.
Hand over the data: The Cyberspace Administration of China (CAC) will require any “entities or nodes” that provide “blockchain information services” to collect users’ real names and national ID or telephone numbers, and allow government officials to access that data.
It will ban companies from using blockchain technology to “produce, duplicate, publish, or disseminate” any content that Chinese law prohibits. Last year, internet users evaded censors by recording the content of two banned articles on the Ethereum blockchain. The rules, first proposed in October, will go into effect next month.
Defeating the purpose? For more than a year, China has been cracking down on cryptocurrency trading and its surrounding industry while also singing the praises of
