The Online Cohorts: A Potential Blind Sport

April 15, 2020

In a conversation last week, a teacher told me, “We are not prepared to teach classes online.” I sympathized. What appears trivial to a person who routinely uses a range of technology, a person accustomed to automatic teller machines, a mobile phone, and an Alexa device may be befuddled. Add to the sense of having to learn about procedures, there is the challenge of adopting in person skills to instructing students via a different method; for example, Google Hangouts, Zoom, and other video conferencing services. How is that shift going? There are anecdotal reports that the shift is not going smoothly.

That’s understandable. More data will become available as researchers and hopefully some teachers report the efficacy of the great shift from a high touch classroom to a no touch digital setting.

I noted “Students Often Do Not Question Online Information.” The article provides a summary of research that suggests:

students struggle to critically assess information from the Internet and are often influenced by unreliable sources.

Again, understandable.

The article points out a related issue:

“Having a critical attitude alone is not enough. Instead, Internet users need skills that enable them to distinguish reliable from incorrect and manipulative information. It is therefore particularly important for students to question and critically examine online information so they can build their own knowledge and expertise on reliable information,” stated Zlatkin-Troitschanskaia. [Professor Olga Zlatkin-Troitschanskaia from JGU. The study was carried out as part of the Rhine-Main Universities (RMU) alliance.]

Online is a catalyst. The original compound is traditional classroom teaching methodologies. The new element is online. The result appears to raise the possibility of a loss of certain thinking skills.

Net net: A long period of adaptation may be ahead. The problem of humans who cannot do math or think in a manner that allows certain statements to be classified as bunk and others as not bunk is likely to have a number of downstream consequences.

In short, certain types of thinking and critical analysis may become quite rare. Informed decisions may not be helpful if the information upon which a choice is based operates from a different type of fact base.

Maybe not so good?

Google Told to Rein in Profits

December 5, 2017

Google makes a lot of money with their advertising algorithms.  Every quarter their profit looms higher and higher, but the San Francisco Gate reports that might change in the article, “Google Is Flying High, But Regulatory Threats Loom.”  Google and Facebook are being told they need to hold back their hyper efficient advertising machines.  Why?  Possible Russian interference in the 2016 elections and the widespread dissemination of fake news.

New regulations would require Google and Facebook to add more human oversight into their algorithms.  Congress already has a new bill on the floor with new regulations for online political ads to allow more transparency.  Social media sites like Twitter and Facebook already making changes, but Google has not done anything and will not get a free pass.

It’s hard to know whether Congress or regulators will actually step up and regulate the company, but there seems to be a newfound willingness to consider such action,’ says Daniel Stevens, executive director of the Campaign for Accountability, a nonprofit watchdog that tracks Google spending on lobbyists and academics. ‘Google, like every other industry, should not be left to its own devices.’

Google has remained mostly silent, but has made a statement that they will increase “efforts to improve transparency, enhance disclosures, and reduce foreign abuse.”  Google is out for profit like any other company in the world.  The question is if they have the conscience to comply or will find a way around it.

Semantic Scholar Expanding with Biomedical Lit

November 29, 2017

Academic publishing is the black hole of the publishing world.  While it is a prestigious honor to have your work published by a scholar press or journal, it will not have a high circulation.  One reason that academic material is blocked behind expensive paywalls and another is that papers are not indexed well.  Tech Crunch has some good news for researchers: “Allen institute For AI’s Semantic Scholar Adds Biomedical Papers To Its AI-Sorted Corpus.”

The Allen Institute for AI started the Semantic Scholar is an effort to index scientific literature with NLP and other AI algorithms.  Semantic Scholar will now include biomedical texts in the index.  There is way too much content available for individuals to read and create indices.  AI helps catalog and create keywords for papers by scanning an entire text, pulling key themes, and adding it to the right topic.

There’s so much literature being published now, and it stretches back so far, that it’s practically impossible for a single researcher or even a team to adequately review it. What if a paper from six years ago happened to note a slight effect of a drug byproduct on norepinephrine production, but it wasn’t a main finding, or was in a journal from a different discipline?

Scientific studies are being called into question, especially when the tests are funded by corporate entities.  It is important to verify truth from false information as we consume more and more each day.  Tools like Semantic Scholar are key to uncovering the truth.  It is too bad it does not receive more attention.

Dark Web Predator Awaits Sentencing

November 15, 2017

Here we have one of the darker corners of the Dark Web. A brief but disturbing article at the UK’s Birmingham Mail reports, “Birmingham University Academic Dr Matthew Falder Led Horrific Dark Web Double Life as ‘666devil’.” The 28-year-old academic in question has pled guilty to 137 charges, most if not all, it seems, of vile crimes against children. Reporter James Cartledge writes:

Since 2010, the geophysicist, who worked at Birmingham University till September, had degraded and humiliated more than 50 victims online using the names ‘666devil’ and ‘evilmind’. … He admitted the offences at a hearing at Birmingham Crown Court on Monday. He was arrested on June 21 this year and has been held in custody since that date. Falder, of Edgbaston, Birmingham, posed as a woman on sites such as Gumtree to trick his victims into sending him naked or partially-clothed images of themselves. The disgraced geophysicist then threatened to expose his victims if they did not send severe and depraved abuse images of themselves. He then distributed the images.

It gets worse from there. We’re told this is the first time the UK’s National Crime Agency had delved into the Dark Web’s hidden forums that share and discuss such “dark” material. Falder is scheduled to be sentenced on December 7 and shall remain in custody in the meantime.

Even Genius Kids Need Teachers

November 14, 2017

Geniuses are supposed to have the innate ability to quickly learn and apply information without being taught.  It is almost like magic what they can do, but even with their awe-inspiring intellects, geniuses need their own mentors.  The Independent wrote about a study that proved geniuses need guidance, “Psychologists Studies 5000 Genius Kids For 45 Years-Here Are Their 6 Takeaways.”

Started in 1971, the “Study of Mathematically Precocious Youth” (SMPY) followed 5000 American children with intelligence measured in the 0.01%, 0.1%, and 1% of all students.  The study’s facilitators learned that the children led extraordinary lives that ranged from them being patent holders, they earned doctorates or graduate degrees, and are in the top 5% of income earners.  One problem is that these children were often ignored by their teachers because they were already meeting their potential.  Teachers had to spend more time helping lower students achieve their academic requirements.

They also learned that skipping a grade can help and intelligence is varied.  The latter means that intelligence cannot be prepackaged, one size fits all, instead, it comes in different forms.  Also despite how much they are loathed, standardized tests do have some predictive ability to measure genius kids success in life.  Perhaps the most interesting factoid is something that is taught in business classes, mindfulness, and other life coaching strategies:

The psychologist Carol Dweck has found that successful people tend to keep what’s known as a “growth mindset” as opposed to a “fixed mindset.” They view themselves as fluid, changing beings that can adapt and grow — they are not static.

 

SMPY agrees with that assessment, but it also has found that the earliest signs of cognitive ability in kids can predict how well they’ll do later in life, ignoring all the practice that may or may not come in between.

Genius kids are valuable as individuals and their intellect can help the world, but the bigger problem is trying to find ways to help them achieve when the rest of the world is trying to catch up.

Mobile Technology Dad Still Waiting for Dream to Become Reality

November 2, 2017

Steve Jobs and Bill Gates are the poster children for modern technology, but more people helped bring about the revolution.  One such person is Alan Kay, often referred to as the father of mobile computing.  He directed a research team at Xerox PARC, developed the SmallTalk programming language, and also worked the Xerox Alto personal computer.  He also advocated that computers could be used as tools for creativity and learning.  Kay sat down for an interview with Fast Company, printed in the article, “The Father Of Mobile Computing Is Not Impressed.”

Kay began the interview that Jobs was not the kind of person to befriend and animation studio Pixar was the most honest money Jobs made.  He mentioned that Jobs was also trying to talk the government into giving tax breaks for companies that put computers in schools.  Back in the twentieth century, Kay designed a mobile device that was the predecessor to a tablet.  Called the Dynabook, it had physical buttons implanted in it and was never released for the consumer market.  However, the Dynabook exists in some form today as the iPad.  Kay complained that there is not a place to put a pen on the iPad, however.

After a brief explanation about human society and the desire to learn, he begins to talk about his idea of mobile computing.  One of the things he liked about the earliest Mac computers was that they allowed people to undo their learning and explore how to use a computer, but the iPhone is stupid:

So, this is like less than what people got with Mac in 1984. Mac had a really good undo. It allowed you to explore things. Mac had multitasking. The iPhone is basically giving one little keyhole and if you do something wrong, you actually go back out and start the app over again.

 

Think about this. How stupid is this? It’s about as stupid as you can get. But how successful is the iPhone? It’s about as successful as you can get, so that matches you up with something that is the logical equivalent of television in our time.

Kay spends most of the interview speaking about how people learn, how education has changed, and some philosophical stuff.  It is more about how to improve ourselves than an interview about mobile computing.

Google Supports Outraged Scholars

October 2, 2017

Google has taken issue with a recent list from the Campaign for Accountability (CfA), TechCrunch reports in, “Google Responds to Academic Funding Controversy—with a GIF.” Writer Frederic Lardinois reports that the CfA recently released a list of policy experts and academics who, they say, had received Googley dollars last year. The only problem—many who found themselves on the list dispute their inclusion, saying they had not received any funding from Google or, if they had, it was unrelated to the work the CfA specified. Google issued a response, supporting the protesting experts and academics as well as defending its support of researchers in general. The company also struck back; the article explains:

And in a direct attack on CfA, Google also notes that while the group advocates for transparency, its own corporate funders remain in the shadows. The only backer we know of is Oracle, which is obviously competing with Google in many areas. The group has also recently taken on SolarCity/Tesla. In its blog post, Google also argues that ‘AT&T, the MPAA, ICOMP, FairSearch and dozens more’ fund similar campaigns.

Google later created a GIF in response to requests for elaboration. It shares a series of tweets from some of the affected scholars, in which they detail just where the CfA went wrong in each of their cases. Lardinois continues:

It’s not often that a company like Google makes its own GIF in response to a request for comment, but I gather this goes to show that Google wants to move on from this discussion and let the academics speak for themselves. While the CfA’s methods are less than ideal, there are legitimate questions about how even small amounts of funding can influence research.

So far, Lardinois notes, public discussion on how funding can influence research have centered around pharmaceuticals. He projects it will soon grow, however, to include policy research as tech companies ramp up their funding programs

Academic Publication Rights Cause European Dispute

September 4, 2017

Being published is the bread and butter of intellectuals, especially academics. publication, in theory, is a way for information to be shared across the globe, but it also has become big business. In a recent Chemistry World article the standoff between Germany’s Project DEAL (a consortium comprised of German universities) and Dutch publisher, Elsevier, is examined along with possible fall-out from the end result.

At the heart of the dispute is who controls the publications. Currently, Elsevier holds the cards and has wielded their power to make a clear point on the matter. Project DEAL, though, is not going down without a fight and Chemistry World quotes Horst Hippler, a physical chemist and chief negotiator for Project DEAL, as saying,

In the course of digitisation, science communication is undergoing a fundamental transformation process. Comprehensive, free and – above all – sustainable access to scientific publications is of immense importance to our researchers. We therefore will actively pursue the transformation to open access, which is an important building block in the concept of open science. To this end, we want to create a fair and sustainable basis through appropriate licensing agreements with Elsevier and other scientific publishers.

As publications are moving farther from ink and paper and more to digital who owns the rights to the information is becoming murkier. It will be interesting to see how this battle plays out and if any more disgruntled academics jump on board.

Seventeen Visions of the Future From Microsoft Researchers

March 31, 2017

Here’s a bit of PR from Microsoft that could pay off in many ways, should the company be wise enough to listen to these women. Microsoft’s blog posts, “17 for ’17: Microsoft Researchers on What to Expect in 2017 and in 2027.” As part of their Computer Science Education Week, the company shares 17 well-informed perspectives on the future of tech, presented by 17 talented researchers. On the way to introducing these insights, the post reminds us:

In this ‘age of acceleration,’ in which advances in technology and the globalization of business are transforming entire industries and society itself, it’s more critical than ever for everyone to be digitally literate, especially our kids. This is particularly true for women and girls who, while representing roughly 50 percent of the world’s population, account for less than 20 percent of computer science graduates in 34 OECD countries, according to this report. This has far-reaching societal and economic consequences.

Consequences like a worldwide shortage of qualified computer scientists, which could be eased by a surge of women entering the field. That’s why they call personnel management ”human resources,” after all.

We are pleased to see one particular researcher on the list, Sue Dumais, who happens to be an alum of the historic Bell Labs. Dumais now works as deputy managing director at Microsoft’s Redmond, Washington, lab. Her view for 2017 makes perfect sense—more progress in, and reliance upon, deep learning models. Among other things, she expects these models to continue improving internet search results. What about further down the road? Here’s Dumais’ vision:

What will be the key advance or topic of discussion in search and information retrieval in 2027?

The search box will disappear. It will be replaced by search functionality that is more ubiquitous, embedded and contextually sensitive. We are seeing the beginnings of this transformation with spoken queries, especially in mobile and smart home settings.  This trend will accelerate with the ability to issue queries consisting of sound, images, or video, and with the use of context to proactively retrieve information related to the current location, content, entities, or activities without explicit queries.

The post urges readers to share this list, in the hope that it will inspire talented kids of all genders to pursue careers in computer science.

You Too, Can Learn Linear Algebra

January 24, 2017

Algebra was invented in Persia nearly one thousand years ago. It is one of the fundamental branches of mathematics and its theories are applied to many industries.  Algebra ranges from solving for x to complex formulas that leave one scratching their head.  If you are interested in learning linear algebra, then you should visit Sheldon Axler’s Web site.  Along with an apparent love for his pet cat, Axler is a professor of mathematics at San Francisco State University.

On his Web site, Axler lists the various mathematics books he has written and contributed too.  It is an impressive bibliography and his newest book is titled, Linear Algebra Abridged.  He describes the book as:

Linear Algebra Abridged is generated from Linear Algebra Done Right (third edition) by excluding all proofs, examples, and exercises, along with most comments. Learning linear algebra without proofs, examples, and exercises is probably impossible. Thus this abridged version should not substitute for the full book. However, this abridged version may be useful to students seeking to review the statements of the main results of linear algebra.

Algebra can be difficult, but as Axler wrote above learning linear algebra without proofs is near impossible.  However, if you have a grounded understanding of algebra and are simply looking to brush up or study linear principles without spending a sizable chunk on the textbook, then this is a great asset.  The book is free to download from Axler’s Web site, along with information on how to access the regular textbook.
