WEF Report: “Decentralized autonomous organizations are disrupting whole sectors. From finance to social networking to philanthropy, these code-driven, community-governed entities are changing the way we work. Yet these organizations also confront challenges of cybersecurity, governance, and regulatory uncertainty. The Crypto Impact and Sustainability Accelerator and Wharton Blockchain and Digital Asset Project have teamed up with an international group of crypto experts, civil society leaders, and builders to examine this nascent, but critical, emerging form…(More)”.
AI Can Predict Potential Nutrient Deficiencies from Space
Article by Rachel Berkowitz: “Micronutrient deficiencies afflict more than two billion people worldwide, including 340 million children. This lack of vitamins and minerals can have serious health consequences. But diagnosing deficiencies early enough for effective treatment requires expensive, time-consuming blood draws and laboratory tests.
New research provides a more efficient approach. Computer scientist Elizabeth Bondi and her colleagues at Harvard University used publicly available satellite data and artificial intelligence to reliably pinpoint geographical areas where populations are at high risk of micronutrient deficiencies. This analysis could potentially pave the way for early public health interventions.
Existing AI systems can use satellite data to predict localized food security issues, but they typically rely on directly observable features. For example, agricultural productivity can be estimated from views of vegetation. Micronutrient availability is harder to calculate. After seeing research showing that areas near forests tend to have better dietary diversity, Bondi and her colleagues were inspired to identify lesser-known markers for potential malnourishment. Their work shows that combining data such as vegetation cover, weather and water presence can suggest where populations will lack iron, vitamin B12 or vitamin A.
The team examined raw satellite measurements and consulted with local public health officials, then used AI to sift through the data and pinpoint key features. For instance, a food market, inferred based on roads and buildings visible, was vital for predicting a community’s risk level. The researchers then linked these features to specific nutrients lacking in four regions’ populations across Madagascar. They used real-world biomarker data (blood samples tested in labs) to train and test their AI program….(More)”.
10 learnings from considering AI Ethics through global perspectives
Blog by Sampriti Saxena and Stefaan G. Verhulst: “Artificial Intelligence (AI) technologies have the potential to solve the world’s biggest challenges. However, they also come with certain risks to individuals and groups. As these technologies become more prevalent around the world, we need to consider the ethical ramifications of AI use to identify and rectify potential harms. Equally, we need to consider the various associated issues from a global perspective, not assuming that a single approach will satisfy different cultural and societal expectations.
In February 2021, The Governance Lab (The GovLab), the NYU Tandon School of Engineering, the Global AI Ethics Consortium (GAIEC), the Center for Responsible AI @ NYU (R/AI), and the Technical University of Munich’s (TUM) Institute for Ethics in Artificial Intelligence (IEAI) launched AI Ethics: Global Perspectives. …A year and a half later, the course has grown to 38 modules, contributed by 40 faculty members representing over 20 countries. Our conversations with faculty members and our experiences with the course modules have yielded a wealth of knowledge about AI ethics. In keeping with the values of openness and transparency that underlie the course, we summarized these insights into ten learnings to share with a broader audience. In what follows, we outline our key lessons from experts around the world.
Our Ten Learnings:
- Broaden the Conversation
- The Public as a Stakeholder
- Centering Diversity and Inclusion in Ethics
- Building Effective Systems of Accountability
- Establishing Trust
- Ask the Right Questions
- The Role of Independent Research
- Humans at the Center
- Our Shared Responsibility
- The Challenge and Potential for a Global Framework…(More)”.
From Knowing to Doing: Operationalizing the 100 Questions for Air Quality Initiative
Report by Jessica Seddon, Stefaan G. Verhulst and Aimee Maron: “…summarizes the September 2021 capstone event that wrapped up 100 Questions for Air Quality, led by GovLab and World Resources Institute (WR). This initiative brought together a group of 100 atmospheric scientists, policy experts, academics and data providers from around the world to identify the most important questions for setting a new, high-impact agenda for further investments in data and data science. After a thorough process of sourcing questions, clustering and ranking them – the public was asked to vote. The results were surprising: the most important question was not about what new data or research is needed, but on how we do more with what we already know to generate political will and investments in air quality solutions.
Co-hosted by Clean Air Fund, Climate and Clean Air Coalition, and Clean Air Catalyst, the 2021 roundtable discussion focused on an answer to that question. This conference proceeding summary reflects early findings from that session and offers a starting point for a much-needed conversation on data-to-action. The group of experts and practitioners from academia, businesses, foundations, government, multilateral organizations, nonprofits, and think tanks have not been identified so they could speak freely….(More)”.
The Behavioral Economics Guide 2022
Editorial by Kathleen Vohs & Avni Shah: “This year’s Behavioral Economics Guide editorial reviews recent work in the areas of self-control and goals. To do so, we distilled the latest findings and advanced a set of guiding principles termed the FRESH framework: Fatigue, Reminders, Ease, Social influence, and Habits. Example findings reviewed include physicians giving out more prescriptions for opioids later in the workday compared to earlier (fatigue); the use of digital reminders to prompt people to re-engage with goals, such as for personal savings, from which they may have turned away (reminders); visual displays that give people data on their behavioral patterns so as to enable feedback and active monitoring (ease); the importance of geographically-local peers in changing behaviors such as residential water use (social influence); and digital and other tools that help people break the link between aspects of the environment and problematic behaviors (habits). We used the FRESH framework as a potential guide for thinking about the kinds of behaviors people can perform in achieving the goal of being environmental stewards of a more sustainable future…(More)”.
Technology is Not Neutral: A Short Guide to Technology Ethics
Book by Stephanie Hare: “It seems that just about every new technology that we bring to bear on improving our lives brings with it some downside, side effect or unintended consequence.
These issues can pose very real and growing ethical problems for all of us. For example, automated facial recognition can make life easier and safer for us – but it also poses huge issues with regard to privacy, ownership of data and even identity theft. How do we understand and frame these debates, and work out strategies at personal and governmental levels?
Technology Is Not Neutral: A Short Guide to Technology Ethics addresses one of today’s most pressing problems: how to create and use tools and technologies to maximize benefits and minimize harms? Drawing on the author’s experience as a technologist, political risk analyst and historian, the book offers a practical and cross-disciplinary approach that will inspire anyone creating, investing in or regulating technology, and it will empower all readers to better hold technology to account…(More)”.
Are blockchains decentralized?
Trail of Bits report: “Blockchains can help push the boundaries of current technology in useful ways. However, to make good risk decisions involving exciting and innovative technologies, people need demonstrable facts that are arrived at through reproducible methods and open data.
We believe the risks inherent in blockchains and cryptocurrencies have been poorly described and are often ignored—or even mocked—by those seeking to cash in on this decade’s gold rush.
In response to recent market turmoil and plummeting prices, proponents of cryptocurrency point to the technology’s fundamentals as sound. Are they?
Over the past year, Trail of Bits was engaged by the Defense Advanced Research Projects Agency (DARPA) to examine the fundamental properties of blockchains and the cybersecurity risks associated with them. DARPA wanted to understand those security assumptions and determine to what degree blockchains are actually decentralized.
To answer DARPA’s question, Trail of Bits researchers performed analyses and meta-analyses of prior academic work and of real-world findings that had never before been aggregated, updating prior research with new data in some cases. They also did novel work, building new tools and pursuing original research.
The resulting report is a 30-thousand-foot view of what’s currently known about blockchain technology. Whether these findings affect financial markets is out of the scope of the report: our work at Trail of Bits is entirely about understanding and mitigating security risk.
The report also contains links to the substantial supporting and analytical materials. Our findings are reproducible, and our research is open-source and freely distributable. So you can dig in for yourself.
Key findings
- Blockchain immutability can be broken not by exploiting cryptographic vulnerabilities, but instead by subverting the properties of a blockchain’s implementations, networking, and consensus protocols. We show that a subset of participants can garner undue, centralized control over the entire system:
- While the encryption used within cryptocurrencies is for all intents and purposes secure, it does not guarantee security, as touted by proponents.
- Bitcoin traffic is unencrypted; any third party on the network route between nodes (e.g., internet service providers, Wi-Fi access point operators, or governments) can observe and choose to drop any messages they wish.
- Tor is now the largest network provider in Bitcoin; just about 55% of Bitcoin nodes were addressable only via Tor (as of March 2022). A malicious Tor exit node can modify or drop traffic….(More)”
Smartphone apps in the COVID-19 pandemic
Paper by Jay A. Pandit, Jennifer M. Radin, Giorgio Quer & Eric J. Topol: “At the beginning of the COVID-19 pandemic, analog tools such as nasopharyngeal swabs for PCR tests were center stage and the major prevention tactics of masking and physical distancing were a throwback to the 1918 influenza pandemic. Overall, there has been scant regard for digital tools, particularly those based on smartphone apps, which is surprising given the ubiquity of smartphones across the globe. Smartphone apps, given accessibility in the time of physical distancing, were widely used for tracking, tracing and educating the public about COVID-19. Despite limitations, such as concerns around data privacy, data security, digital health illiteracy and structural inequities, there is ample evidence that apps are beneficial for understanding outbreak epidemiology, individual screening and contact tracing. While there were successes and failures in each category, outbreak epidemiology and individual screening were substantially enhanced by the reach of smartphone apps and accessory wearables. Continued use of apps within the digital infrastructure promises to provide an important tool for rigorous investigation of outcomes both in the ongoing outbreak and in future epidemics…(More)”.
Many researchers say they’ll share data — but don’t
Article by Clare Watson: “Most biomedical and health researchers who declare their willingness to share the data behind journal articles do not respond to access requests or hand over the data when asked, a study reports1.
Livia Puljak, who studies evidence-based medicine at the Catholic University of Croatia in Zagreb, and her colleagues analysed 3,556 biomedical and health science articles published in a month by 282 BMC journals. (BMC is part of Springer Nature, the publisher of Nature; Nature’s news team is editorially independent of its publisher.)
The team identified 381 articles with links to data stored in online repositories and another 1,792 papers for which the authors indicated in statements that their data sets would be available on reasonable request. The remaining studies stated that their data were in the published manuscript and its supplements, or generated no data, so sharing did not apply.
But of the 1,792 manuscripts for which the authors stated they were willing to share their data, more than 90% of corresponding authors either declined or did not respond to requests for raw data (see ‘Data-sharing behaviour’). Only 14%, or 254, of the contacted authors responded to e-mail requests for data, and a mere 6.7%, or 120 authors, actually handed over the data in a usable format. The study was published in the Journal of Clinical Epidemiology on 29 May.
Puljak was “flabbergasted” that so few researchers actually shared their data. “There is a gap between what people say and what people do,” she says. “Only when we ask for the data can we see their attitude towards data sharing.”
“It’s quite dismaying that [researchers] are not coming forward with the data,” says Rebecca Li, who is executive director of non-profit global data-sharing platform Vivli and is based in Cambridge, Massachusetts…(More)”.
It’s in Everyone’s Interest to Sustain our Open Digital Future
Article by Govind Shivkumar and Alex Krasodomski-Jones: “…Omidyar Network was proud to support the creation of “The Open Road,” a new report by our partners at Demos that vividly highlights the many dangers facing open infrastructure — and lays out a clear and achievable path to securing its sustainable future. In short, the report urges philanthropies to take concrete steps, with significant funding, to bolster open-source software and open standards, and the people who keep the infrastructure working.
The value of open-source code and the movement behind it
Everything from hospitals and banks to social media and messaging platforms run on open-source software; that is, mostly free “source code” that anyone can inspect, modify, and enhance to build their own digital applications. In complement, open standards — like HTML, a common way of coding a website — help facilitate interoperability and data exchanges between different products or services. Both of these “encourage a decentralized community of developers to collaborate on projects and jointly benefit from the resulting software”.
A secure, open technology system is immensely valuable to companies and governments. It facilitates connections between their technologies and other systems, which increases the value of their tools; it is easy to adopt and make changes; and it avoids the pitfalls of reinventing the wheel or reinvesting resources. Because of that vast flexibility, developers and engineers can innovate for the user’s needs faster and more cost-effectively, giving the public a meaningful choice of which interconnected apps, devices, technologies they want to use.
“More openness means more innovation. More transparency means more scrutiny, which means fewer overlooked security vulnerabilities. Openness favors the development of ‘good technology,’ which embeds privacy, security, and other protections in its design.”
The challenges facing open infrastructure
The ecosystem is vast and acutely vulnerable. Period catastrophes like the Heartbleed bug which was exposed in 2014, and later security flaws, such as log4shell and log4J, threatened millions of digital applications worldwide. Other weaknesses are simply the result of neglect and lack of proper investment and upkeep. When security vulnerabilities cause cracks in the infrastructure, allowing malicious actors to wreak havoc, the startled world briefly takes notice…(More)”
