Nutrition Science Is Broken. This New Egg Study Shows Why. Jul 2019
"Nutrition research tends to be unreliable because nearly all of it is based on observational studies, which are imprecise, have no controls, and don’t follow an experimental method."

"Other nutrition research critics, such as John Ioannidis of Stanford University, have been similarly scathing in their commentary. They point out that observational nutrition studies are essentially just surveys"

What is Ethnography? | Anthropology@Princeton
"Ethnography is a research method central to knowing the world from the standpoint of its social relations. It is a qualitative research method predicated on the diversity of culture at home (wherever that may be) and abroad. Ethnography involves hands-on, on-the-scene learning — and it is relevant wherever people are relevant. Ethnography is the primary method of social and cultural anthropology, but it is integral to the social sciences and humanities generally, and draws its methods from many quarters, including the natural sciences."

"Anthropology is the comprehensive study of human development, culture, and change throughout the world, past and present. "

An audacious new plan will make all science free. Can it work? | New Scientist
"We fund scientific research through our taxes but often have to pay a hefty fee to read its findings. An uprising aims to bring the knowledge paywall crashing down"

"This all adds up to a very lucrative business. In 2013, academic publishing generated global revenues of $25.2 billion. Profit margins are reported to be between 30 and 40 per cent: the figure is hard to verify, although not disputed by the industry’s leading trade body, the International Association of Scientific, Technical and Medical Publishers. Indeed, last year Elsevier, the world’s largest academic publisher, reported a profit margin of nearly 37 per cent, amounting to £913 million. In other words, academic publishing is one of the most profitable businesses in the world."

Is the FDA Too Conservative or Too Aggressive?: A Bayesian Decision Analysis of Clinical Trial Design, Aug 2015, Vahid Montazerhodjat & Andrew W. Lo
Via Tom Hazlett, Nov 2017

NBER Working Paper No. 21499
Issued in August 2015
NBER Program(s):Health Care, Health Economics

Implicit in the drug-approval process is a trade-off between Type I and Type II error. We explore the application of Bayesian decision analysis (BDA) to minimize the expected cost of drug approval, where relative costs are calibrated using U.S. Burden of Disease Study 2010 data. The results for conventional fixed-sample randomized clinical-trial designs suggest that for terminal illnesses with no existing therapies such as pancreatic cancer, the standard threshold of 2.5% is substantially more conservative than the BDA-optimal threshold of 27.9%. However, for relatively less deadly conditions such as prostate cancer, 2.5% is more risk-tolerant or aggressive than the BDA-optimal threshold of 1.2%. We compute BDA-optimal sizes for 25 of the most lethal diseases and show how a BDA-informed approval process can incorporate all stakeholders’ views in a systematic, transparent, internally consistent, and repeatable manner.

Satellite Constellations: A Critical Assessment - Northern Sky Research Apr 2018
From the email, "LEO-HTS Constellations Present Great Promise but Challenging Business Cases"

From graphic, studied following constellations:
SES mPower (aka O3b)

"NSR predicts two, out of the five Non-GEO HTS constellations analyzed, do not have a viable business case and will not be sustainable, if launched. The remaining three will generate 12% of overall satcom market revenues over the next decade. Costly systems and replenishment cycles, matched against funding challenges, demand questions, and extraordinary technical and regulatory complexity, will separate contenders from pretenders in the high stakes constellations market."

"The associated CAPEX, including replenishment costs, is one the biggest hurdles to HTS, EO, and IoT constellation business plans"

"Vertical integration trends – such as in-house manufacturing and, in the case of SpaceX, incorporating that with its own launch services - aimed at lowering costs further actually add another layer of complexity that is greatly underestimated. Supply chain management is a momentous challenge, ..."

"There is a compelling level of optimism towards Non-GEO constellations, ... However, financial success for LEO constellations depends on their ability to bring pricing down to a level competitive with terrestrial networks and make the services affordable to target markets"

DARPA's AI Spectrum Management Challenge Completes its First Round - IEEE Spectrum Dec 2017
"19 teams qualified to compete in the first, year-long round of the challenge, which will ultimately last for two more years. Last January, DARPA opened the doors for the competition, inviting any applications from teams who thought they were up to the task. Thirty teams qualified and have had access to the Colosseum for the past year. They’ve gone head to head in round-robin style scrimmages each month to narrow the field to the 19 that competed in the last series of contests that ended on 13 December."

"In the mornings, all attendees offered a 20-minute talk about their work. In the afternoons, they split into groups. . . . Each group would sum up its discussions in a 10-minute presentation on the last day."

"sometimes connects two or more researchers for conversations before the meeting"

"'speed networking sessions'. Scientists are organized into pairs, based on mutual interests, to chat for five to eight minutes before moving to their next partner."

Paying Professors: Inside Google’s Academic Influence Campaign - WSJ July 2017
"Google operates a little-known program to harness the brain power of university researchers to help sway opinion and public policy, cultivating financial relationships with professors at campuses from Harvard University to the University of California, Berkeley.

Over the past decade, Google has helped finance hundreds of research papers to defend against regulatory challenges of its market dominance, paying $5,000 to $400,000 for the work, The Wall Street Journal found.

Some researchers share their papers before publication and let Google give suggestions, according to thousands of pages of emails obtained by the Journal in public-records requests of more than a dozen university professors. The professors don't always reveal Google's backing in their papers, and few disclosed the financial ties in later articles on the same or similar topics, the Journal found."

"Google has funded roughly 100 academic papers on public-policy matters since 2009, according to a Journal analysis of data compiled by the Campaign for Accountability, an advocacy group that has campaigned against Google and receives funds from Google's rivals, including Oracle Corp. Most mentioned Google's funding.

Another 100 or so research papers were written by authors with financing by think tanks or university research centers funded by Google and other tech firms, the data show. Most of those papers didn't disclose the financial support by the companies, the Campaign for Accountability data show."

"Ryan Calo, then at Stanford University, received one of the $400,000 awards in 2010, though he didn't disclose the funding in one of the two papers he later published on privacy protection."

Crowd-based peer review can be good and fast : Nature News & Comment. Benjamin List. May 2017
"I am not proposing what is sometimes referred to as crowdsourced reviewing, in which anyone can comment on an openly posted manuscript. I believe that anonymous feedback is more candid, and that confidential submissions give authors space to decide how to revise and publish their work. I envisioned instead a protected platform whereby many expert reviewers could read and comment on submissions, as well as on fellow reviewers’ comments."

" Compared with our control experiments, we found that the crowd was much faster (days versus months), and collectively provided more-comprehensive feedback.

Our authors reacted positively, saying that they appreciated the comprehensiveness of the crowd’s comments and the speedy turnaround."

Will Communications Theory Finally Make Itself Redundant? A View from the Academic Trenches | Petar Popovski - IEEE Communications Society
He starts with an old Balkan joke about a lawyer and a tree

He asserts that “there are clear signs that the communication engineering, and especially research in communication engineering, is losing its traction and gives way to other engineering disciplines, such as e.g. machine learning.”

He then suggests three “tracks that have the potential to drive a new and exciting research in communication theory over a longer period”

1. Communication under adversarial impact: “when dealing with adversarial impact instead of dealing only with physical limits, it is much more difficult, if at all possible, to reach a saturation point for research, since the adversary is doing his/her research as well”

2. Interaction among vertical services: “What are the fundamental communication-theoretic problems that arise from interaction among multiple vertical connections, each with different requirements? … In spectrum regulation, and especially for unlicensed spectrum, there is the tendency to make spectrum usage rules generic, as much as possible independent of the requirements of the vertical service. Net neutrality also ... Building a communication theory that addresses the fundamentals of interaction among multiple vertical services, has the potential to change the way we configure communication systems, as well as utilize and regulate the spectrum and communication services.”

3. Communication beyond dedicated electronic circuits: “communication theory leans towards a mathematical sub-discipline. The latter means that communication theory is not necessarily applied only to electronic circuits that are built for communication and has wider implications.”

The mathematics of science's broken reward system : Nature News & Comment - Nov 2016
“Whenever quantitative metrics are used as proxies to evaluate and reward scientists,” write Smaldino and McElreath, “those metrics become open to exploitation if it is easier to do so than to directly improve the quality of research.” That’s basically a statement of Goodhart’s law, familiar to economists: when a measure of success becomes a target, it loses its worth.

10 years ago science was broken – I'm making it better - opinion - 25 November 2014 - Test - New Scientist
Interview with John Ioannides. Q. Your proposed solution is to introduce a credibility estimate. How might that work? A. Each scientific paper and major result would have a credibility estimate based on the quality of the research. So for the finding that smoking causes lung cancer, the credibility estimate would be 99.99999 per cent. Conversely, for findings where we have only seen a few cases that drug X may cause severe bleeding, for instance, the credibility estimate might be 1 per cent. It may still be worth publishing because it is important to make sure the drug doesn't cause severe bleeding."

[1304.6690] Massive MIMO for Next Generation Wireless Systems
"Multi-user Multiple-Input Multiple-Output (MIMO) offers big advantages over conventional point-to-point MIMO: it works with cheap single-antenna terminals, a rich scattering environment is not required, and resource allocation is simplified because every active terminal utilizes all of the time-frequency bins. However, multi-user MIMO, as originally envisioned with roughly equal numbers of service-antennas and terminals and frequency division duplex operation, is not a scalable technology. Massive MIMO (also known as "Large-Scale Antenna Systems", "Very Large MIMO", "Hyper MIMO", "Full-Dimension MIMO" & "ARGOS") makes a clean break with current practice through the use of a large excess of service-antennas over active terminals and time division duplex operation. Extra antennas help by focusing energy into ever-smaller regions of space to bring huge improvements in throughput and radiated energy efficiency. Other benefits of massive MIMO include ..."

Diederik Stapel’s Audacious Academic Fraud -
"Diederik Stapel, a Dutch social psychologist, perpetrated an audacious academic fraud by making up studies that told the world what it wanted to hear about human nature." "But the scientific misconduct that has come to light in recent years suggests at the very least that the number of bad actors in science isn’t as insignificant as many would like to believe. In his early years of research — when he supposedly collected real experimental data — Stapel wrote papers laying out complicated and messy relationships between multiple variables. He soon realized that journal editors preferred simplicity. “They are actually telling you: ‘Leave out this stuff. Make it simpler,’ ” Stapel told me. Before long, he was striving to write elegant articles."

Do you need to know math for doing great science? | The Curious Wavefunction, Scientific American Blog Network
"Writing in the Wall Street Journal, biologist E. O. Wilson asks if math is necessary for doing great science. At first glance the question seems rather pointless and the answer trivial; we can easily name dozens of Nobel Prize winners whose work was not mathematical at all. Most top chemists and biomedical researchers have little use for mathematics per se, except in terms of using statistical software or basic calculus. The history of science is filled with scientists like Darwin, Lavoisier and Linnaeus who were poor mathematicians but who revolutionized their fields. But Wilson seems to be approaching this question from two different perspectives and by and large I agree with both of them. The first perspective is from the point of view of students and the second is from the point of view of research scientists. Wilson contends that many students who want to become scientists are put off when they are told that they need to know mathematics well to become great scientists."

Ofcom | Enhancing Spectrum Efficiency - research agenda
"Under this research area, we consider projects looking at existing uses of the radio spectrum and asking whether there are more efficient ways to achieve the same service. Ofcom is undertaking this work because in some cases there may not be sufficient incentives for users to upgrade their systems to more efficient technology and in other cases it may be that proof of concept work is required before users will invest in further understanding new technology."

Sociology: Honour the helpful : Nature : Sep 2012
"What kind of scientist does a department want to hire? The investigator who churns out high-impact papers and travels around the world giving seminars? Or someone with an average publication record who is always discussing other people's work with them, attending seminars and providing feedback on colleagues' papers? Most departments would probably hire the first one and not think twice. I believe the choice is not so straightforward." ... "By reviewing the acknowledgements in immunology papers since 1950, I have found that when principal investigators (PIs) who were frequently thanked by others died unexpectedly, the quality of the papers of their collaborators dropped. In contrast, the quality of co-authors' work changed little after the passing away of PIs who were not particularly helpful to others"
