Africa’s New Generation of Innovators

Clayton M. ChristensenEfosa OjomoDerek van Bever:

FFor years now, business leaders and investors from around the world have waited for the Africa Rising narrative to shift from promise to reality. The continent has understandably been the focus of increasing investment and attention since the turn of this century. With a young, urbanizing population; abundant natural resources; and a growing middle class, Africa seems to have all the ingredients necessary for breakaway growth—perhaps even outstripping the so-called tiger economies of East Asia a generation ago. Indeed, a 2010 report by the McKinsey Global Institute titled “Lions on the Move” expressly made this comparison, forecasting that consumer spending on the continent would grow by 40%, and GDP by $1 trillion, from 2008 to 2020.

Texas schools and districts got their letter grades from state

Julie Chang Melissa B. Taboada:

School districts across Texas pulled in lackluster preliminary grades under the state’s new letter-grade accountability system that debuts Friday.

Various Central Texas districts, including Austin, Leander, Hays, Georgetown, Bastrop, Manor, Elgin, San Marcos, Hutto, Dripping Springs and Elgin received unacceptable grades of Ds and Fs in certain categories, according to a report sent to the Texas Legislature last week that was obtained by the American-Statesman.

Even some nationally ranked campuses, including Round Rock’s Westwood High School and Eanes’ Westlake High, didn’t muster straight As under the new system, and schools that received top marks from the state just a few months ago received unacceptable scores. The grades are meant to give districts and the public a glimpse of how the new system will work when it is finalized next year, and are not official or punitive. The accountability ratings doled out in August still stand.

All The Mathematical Methods I Learned In My University Math Degree Became Obsolete In My Lifetime

Keith Devlin:

If you are connected with the world of K-12 mathematics education, it’s highly unlikely that a day will go by without you uttering, writing, hearing, or reading the term “number sense”. In contrast everyone else on the planet would be hard pressed to describe what it is. Though entering the term into Google will return close to 38 million hits, it has yet to enter the world’s collective consciousness. Stanford mathematician Keith Devlin explains what it is.

When I graduated with a bachelors degree in mathematics from one of the most prestigious university mathematics programs in the world (Kings College London) in 1968, I had acquired a set of skills that guaranteed full employment, wherever I chose to go, for the then-foreseeable future—a state of affairs that had been in existence ever since modern mathematics began some three thousand years earlier. By the turn of the new Millennium, however, just over thirty years later, those skills were essentially worthless, having been very effectively outsourced to machines that did it faster and more reliably, and were made widely available with the onset of first desktop- and then cloud-computing. In a single lifetime, I experienced first-hand a dramatic change in the nature of mathematics and how it played a role in society.

I Can’t Answer These Texas Standardized Test Questions About My Own Poems

Sara Holbrook:

When I realized I couldn’t answer the questions posed about two of my own poems on the Texas state assessment tests (STAAR Test), I had a flash of panic – oh, no! Not smart enough. Such a dunce. My eyes glazed over. I checked to see if anyone was looking. The questions began to swim on the page. Waves of insecurity. My brain in full spin.

The two poems in question are A REAL CASE, appearing on the 2014 Grade 7 STAAR Reading Test, and MIDNIGHT, appearing on the 2013 Grade 8 STAAR Reading Test. Both poems originally appeared in Walking on the Boundaries of Change, Boyds Mills Press, 1998.

Let me begin by confessing that A REAL CASE is my most neurotic poem. I have a pile of them to be sure, but this one is the sour cherry on top. The written evidence of my anxieties, those evil gremlins that ride around on tricycles in my mind shooting my self-confidence with water pistols. How in the name of all that’s moldy did this poem wind up on a proficiency test?

UW-Madison’s Young Americans for Freedom labeled hate group

Late Hardiman:

The Student Coalition for Progress at the University of Wisconsin-Madison recently pushed a petition that alleged University of Wisconsin Madison’s Young Americans for Freedom chapter is a hate group and its members and efforts “create a hostile environment on campus.”

Young Americans for Freedom is a conservative student organization that aims to promote free market economics and Reaganesque principles.

The 3-week-old petition, titled “Denounce Young Americans for Freedom and the alt-right,” also recommended Young Americans for Freedom members be subjected to “intensive diversity training.”

The petition was launched about a month after YAF hosted conservative columnist Ben Shapiro on campus to speak about microaggressions, safe spaces and free speech. The petition decried Shapiro’s visit, claiming it made minority students feel unsafe, and accused Shapiro of denying “systematic and institutional violences” against so-called marginalized communities.

Portrait of the Artist as a Case Study

María Carla Sánchez:

I have been arguing with my undergraduate English students. Nicely and very carefully, but still, we are arguing, and I have the distinct sense I’m losing.

The subject of contention is a certain phrase they have heard often and hold dear: “you write what you know.” Many of them find this statement self-evident and undeniably true, like “Gravity exists,” or 2+2=4.

At first I responded with a question: “But what does it mean to ‘know’ something?” They were not impressed. Our arguments then take various forms: Some of the students insist that Edgar Allan Poe must have contemplated murder, otherwise he never could have written “The Tell-Tale Heart.” I bite the insides of my cheeks and suggest that Poe might have used his imagination to create his stories.

Now we’re talking How voice technology is transforming computing

The Economist:

ANY sufficiently advanced technology, noted Arthur C. Clarke, a British science-fiction writer, is indistinguishable from magic. The fast-emerging technology of voice computing proves his point. Using it is just like casting a spell: say a few words into the air, and a nearby device can grant your wish.
 
 The Amazon Echo, a voice-driven cylindrical computer that sits on a table top and answers to the name Alexa, can call up music tracks and radio stations, tell jokes, answer trivia questions and control smart appliances; even before Christmas it was already resident in about 4% of American households. Voice assistants are proliferating in smartphones, too: Apple’s Siri handles over 2bn commands a week, and 20% of Google searches on Android-powered handsets in America are input by voice. Dictating e-mails and text messages now works reliably enough to be useful. Why type when you can talk?

Which Universities Have the Best Coders in the World?

HackerRank

At HackerRank, millions of developers, including hundreds of thousands of students, from around the world regularly solve coding challenges to improve their coding skills. In order to figure out which colleges have the best coders, we hosted a major University Rankings Competition. Over 5,500 students from 126 schools from around the world participated in the event. Companies also assess developers’ coding skills using HackerRank to hire great developers.

According to our data, the top three best coders in the world hail from:

DO LAW SCHOOLS ADEQUATELY PREPARE STUDENTS FOR PRACTICE? SURVEYS SAY

Robert Kuehn:

Under ABA Accreditation Standard 301, law schools have two educational objectives: prepare their students “for admission to the bar and for effective, ethical, and responsible participation as members of the legal profession.” There has been much concern lately over declining bar passage rates, focusing attention on whether some schools are admitting students who may not be capable of passing the bar exam and whether a school’s program of legal education adequately prepares its graduates for the exam.

In focusing on the bar exam, it’s important not to lose sight of legal education’s primary duty of ensuring that law school prepares students for entry into the legal profession and a successful career. If studies of practicing lawyers and recent law graduates matter, it is clear that law schools are failing, even worse than in preparation for bar admission, to adequately prepare their students for legal practice.

A 2012 study by the National Conference of Bar Examiners (NCBE) analyzed the job activities of newly-licensed lawyers to determine which knowledge domains and professional skills and abilities are most significant to their job. Acquisition of professional skills and abilities were deemed significantly more important to newly-licensed lawyers than legal knowledge — 25 skills and abilities were deemed more important than the highest rated knowledge domain. The percentages of lawyers using these 25 skills in their work (all rated between 89% to 100%) also were all greater than the percentage using the highest rated knowledge domain (86%). Yet these skills and abilities generally are not developed in traditional doctrinal law classes but in the experiential and first-year legal writing courses that, under the ABA standards, need only account for ten percent of a student’s legal education.

In Transition

Judith Curry:

Why did I resign my tenured faculty position?

I’m ‘cashing out’ with 186 published journal articles and two books. The superficial reason is that I want to do other things, and no longer need my university salary. This opens up an opportunity for Georgia Tech to make a new hire (see advert).

The deeper reasons have to do with my growing disenchantment with universities, the academic field of climate science and scientists.

Wrong trousers

I’ve been in school since I was 5 years old. Until a few years ago, I regarded a tenured faculty position at a major university to be a dream job, and I couldn’t imagine doing anything else.

Apart from my own personal career trajectory and the ‘shocks’ that started in 2005 with our hurricanes and global warming paper, and the massive spike in 2009/2010 from Climategate, I’ve found that universities have changed substantially over the past 5-10 years.

At first, I thought the changes I saw at Georgia Tech were due to a change in the higher administration (President, Provost, etc). The academic nirvana under the prior Georgia Tech administration of Wayne Clough, Jean-Lou Chameau and Gary Schuster was a hard act to follow. But then I started to realize that academia and universities nationwide were undergoing substantial changes. I came across a recent article that expresses part of what is wrong: Universities are becoming like mechanical nightingales.

Commentary On Wisconsin’s K-12 School Climate

Alan Borsuk:

The Underestimated Development of 2016 Award: The launch of special education vouchers statewide. Only 206 students statewide qualified in September for these $12,000 vouchers (which was about 10 times what I expected given the narrow eligibility rules). It was a foot in the door, and I’ll be surprised if the rules aren’t changed so that more students can take part in coming years.

The Stuck Needle Award: The state’s new accountability systems. The first results of the Forward test were released in 2016, along with the first round of revised school report cards. The results were not much different from those using the old tests and report cards. Overall, fewer than half of the state’s third- through eighth-graders were rated proficient in reading and language arts. Is this satisfactory? Tell me again, how are we going to move forward in 2017 and beyond?

Obama Leaves the Constitution Weaker Than He Found It

Garrett Epps:

Even worse, however, is the continued conduct of open hostilities in Iraq and Syria against the Islamic State despite the refusal of Congress to approve the military campaign. No one questions that the Constitution applies here; but because the two branches are unable to agree on the scope of American intervention, this most crucial of constitutional guarantees—the power of Congress to authorize military action—has gone by the board. This is not entirely the president’s fault—the administration and its allies have repeatedly begged Congress to at least hold hearings on an authorization bill. As is often the case in history, legislators would prefer to stay out of the arena so that they can later claim credit for victory but disclaim any role in disaster.

And just to underline how obsolete Congressional authorization has become, consider that the most searing foreign-policy attacks on Obama arise from the one occasion on which he announced he would not intervene abroad without Congressional authorization—his 2013 decision not to launch airstrikes against Syria without first going to Congress. Whether he was using constitutional caution as an excuse or not, the Constitution clearly required authorization, while the political class of both parties has treated Obama’s caution as contemptible.

As a civil-libertarian, Obama had his limits. Obama hands over to the Trump administration a National Security Agency that is pursuing a robust a program of domestic and foreign surveillance, under the relatively thin constraints provided by the Foreign Intelligence Surveillance Act Amendments of 2008. The Obama administration has been stunningly aggressive in its incursions on news-gathering by reporters, prosecuting leakers under the Espionage Act and demanding the phone records of 20 Associated Press reporters as part of a leak investigation. These were far beyond the previous norms––and are now part of the background practices inherited by the Trump Administration.

Exclusive: Chinese education giant helps its students game the SAT

Steve Stecklow and Alexandra Harney

When the new SAT was given for the first time in March, the owner of the test took unprecedented steps to stop “bad actors” from collecting and circulating material from the all-important college entrance exam.

But in the months since, China’s largest private education company has been subverting efforts to prevent cheating, Reuters found.

The company, New Oriental Education & Technology Group Inc, has regularly provided items from the tests to clients shortly after the exams are administered. Because material from past SATs is typically reused on later exams, the items New Oriental is distributing could provide test-takers with an unfair advantage.

New Oriental has put some of the exam items on its Chinese website. On Dec. 6, for instance, the Beijing-based company posted a reading passage that had been used on a version of the SAT administered in the United States three days earlier. New Oriental also has been posting information about recent questions on the TOEFL, the English-language exam widely used by colleges to assess foreign applicants. TOEFL questions are also sometimes recycled.

Civics: Drones & The Death Of An American Teenager

Jeremy Scahill:

The U.S. State Department confirmed on January 5 that the man the U.S. government once claimed was the target of the drone strike that killed American teenager Abdulrahman Awlaki in 2011 in Yemen is alive. The department announced that it has designated Ibrahim al Banna “a Specially Designated Global Terrorist (SDGT) under Executive Order (E.O.) 13224.” The U.S. is offering a $5 million reward for information leading to al Banna’s killing or capture.

Al Banna’s name was floated by anonymous U.S. officials as the target of the October 14, 2011, drone strike that killed Awlaki, a 16-year-old U.S. citizen born in Colorado. Awlaki’s family insists he was having dinner with his teenage cousin and some others in Shebwah, Yemen, when they were killed in the strike. The Obama administration has never explained why Awlaki was killed, other than anonymous officials implying he was with a terror target at the time or that it was a lethal mistake. Awlaki’s estranged father, Anwar al Awlaki, was a radical pro-al Qaeda imam whose sermons influenced and inspired many terrorists in the English speaking world. The elder Awlaki, who was also a U.S. citizen, was an enigmatic figure who supported George W. Bush’s 2000 election campaign, spoke at the Pentagon shortly after 9-11, and went on to become an important propaganda figure for the growing radical Islamist movement after the invasions of Afghanistan and Iraq. He was killed in a U.S. drone strike two weeks before his son was killed.

How The U.S. Marshals and Bureau of Prisons Are Trying To Break My Hunger Strike

Martin Gottesfeld:

On the 43rd day of my hunger strike I was told the U.S. Marshalls had ordered my transfer to a facility in New York that was better equipped to handle my medical condition. At that point I had gone about four days without any fluids whatsoever and to make my wishes and refusal to provide medical consent crystal clear, I had written “No IV DNR” on the inside of both my elbows. Hey, if the DOJ wanted to allow notorious federal prosecutor Carmen Ortiz and her lackeys to keep holding me because I tried to protect innocent, learning disabled, teenager Justina Pelletier from abuse, torture, and an agonizing death, then I wanted to make sure they were fully committed to backing Ortiz up as she makes a pet toy and total mockery of our justice system yet again. After all, when Justina was suffering Ortiz’s office couldn’t be bothered to even make a phone call to inquire as to whether her civil and human rights were being upheld (and they weren’t). But I digress, I was not allowed to call my wife before the prison transfer, but I was promised I’d be able to call her upon my arrival.

White Suburban Parents Protest Educational Rights of Black Urban Parents

Laura Waters:

Look at this picture. What do you see? A group of (almost all) white suburban people in front of the New Jersey Statehouse protesting the expansion — indeed, the existence — of public charter schools. As a white suburban N.J. resident I’m a bad proxy for urban parents of color, particularly those relegated to long-failing school districts who rely on (or wait for) seats in high-performing charter schools. So let them speak for themselves.

First, a little context.

The N.J. Board of Education is considering several regulatory changes to the state’s twenty-two year old charter law. These changes would allow the highest-performing charters to hire teachers without traditional certification who have Bachelor’s degrees, 3.0 GPA’s, demonstrate content knowledge and/or have classroom experience. Principals wouldn’t need Master’s degrees and hiring requirements for Business Administrators would be relaxed. In addition, some charter school students would be able to join sports teams in traditional schools and charters would be allowed to hold weighted lotteries to give economically-disadvantaged students better odds of enrollment.

Has Political Correctness Gone off the Rails in America?

Philip Oehmke:

It’s a Friday afternoon in Oberlin, Ohio, around one month before the country heads to the polls to elect Donald Trump as its next president. The final classes and lectures of the week have just ended, and a young woman comes walking by in bare feet with a hula hoop gyrating around her waist while others are performing what seems to be a rhythmic dance to the African music that’s playing. Two black students are rapping.

It’s the kind of scene that could easily play out on a beach full of backpack tourists, but this is unfolding at one of the country’s most expensive universities.

Many female students here have dyed their hair green or blue, they have piercings and their fashion sense seems inspired by “Girls” creator and millennial star Lena Dunham, who, of course, also studied here.

Genetically engineered humans will arrive sooner than you think. And we’re not ready.

Sean Illing:

Bioengineering has already allowed human beings to take control of their own evolution. Whether it’s emergent cloning technologies or advanced gene therapy, we’re quickly approaching a world in which humans can — and will — change the way they live and die.

Michael Bess is a historian of science at Vanderbilt University and the author of a fascinating new book, Our Grandchildren Redesigned: Life in a Bioengineered Society. Bess’s book offers a sweeping look at our genetically modified future, a future as terrifying as it is promising.

Japanese company replaces office workers with artificial intelligence

Justin McCurry:

A future in which human workers are replaced by machines is about to become a reality at an insurance firm in Japan, where more than 30 employees are being laid off and replaced with an artificial intelligence system that can calculate payouts to policyholders.

Fukoku Mutual Life Insurance believes it will increase productivity by 30% and see a return on its investment in less than two years. The firm said it would save about 140m yen (£1m) a year after the 200m yen (£1.4m) AI system is installed this month. Maintaining it will cost about 15m yen (£100k) a year.

The move is unlikely to be welcomed, however, by 34 employees who will be made redundant by the end of March.

The system is based on IBM’s Watson Explorer, which, according to the tech firm, possesses “cognitive technology that can think like a human”, enabling it to “analyse and interpret all of your data, including unstructured text, images, audio and video”.

To build a future for their son, Dallas couple plan $12 million community for young adults with autism

Sabriya Rice:

A Dallas couple is planning to construct a $12 million community for people with autism on nearly 29 acres of land that was formerly a polo ranch in the Denton County town of Cross Roads.

It will include 15 homes, a community center and access to a ‘transitional academy’ that is designed to help young adults with autism develop the skills needed to live and work independently.

Clay Heighten, a retired emergency doctor and founder of a real estate management company, and his wife Debra Caudy, a retired medical oncologist, are leading the project.

The inspiration is their 19-year old son, Jon, who is on the severe end of the autism spectrum and requires a high level of supportive care.

This Is How AI Will Change Your Work In 2017

Artificial intelligence is growing fast. Recent research puts it as a $5 billion market by 2020, and Gartner estimates that 6 billion connected “things” will require AI support by 2018. Connected machines, wearables, and other business tools like voice assistants are already boosting productivity at work and at home.

Two reports just surfaced that tackle the troubling predictions that automation, artificial intelligence, and robots are going to supplant human workers. The McKinsey Global Institute and Glassdoor research indicates that we don’t have to worry that we humans will become obsolete.

Matt Gould, chief strategy officer at Arria NLG, U.K.-based company offering AI technology in data analytics and information delivery, explains that AI has the ability to distill expertise into the machine. “Knowledge work, for the first time, can be produced at volume from NLG-AI systems,” Gould says. “Far from killing the jobs of knowledge workers, this tends to free them up to do what they are paid to do—innovate, model, refine, and improve on the expertise of their business.”

Silencing professor speech to prevent students from being offended — or from fearing discrimination by the professors

Eugene Volokh:

People often support disciplining and even firing professors who say things that are perceived as racist on the grounds that 1) those professors can’t be trusted to evaluate minority students fairly, 2) students will be afraid that they won’t be judged fairly, or 3) students will more broadly lose confidence in the professors (or just couldn’t stand to be in the room with them) or even in the institution, and won’t learn as effectively. I’ve seen these arguments made often, most recently as to the University of Oregon controversy. One response to my Oregon post, for instance — a tweet by @TimothyWright3, “What does the institution say to students of color by allowing [Prof. Nancy] Shurtz back into a classroom?” — seems to be implicitly making these arguments (though it seems to focus most clearly on No. 3. But, again, this is just one example among many.

The Ferguson Effect Lives On

Heather Mac Donald:

The Black Lives Matter crusade against the police continued to cost lives and destroy civil peace in 2016. Two recent estimates of violent crime in the nation’s largest cities show that murders and shootings remained on an upward trajectory this year, as officers backed off of proactive policing. The Brennan Center for Justice projects that murders in the 30 largest cities will be 14 percent higher in 2016 compared with 2015, a stunning increase coming as it does on top of 2015’s already massive homicide rise, which was 14.5 percent in all cities with populations over 250,000 and 20 percent in cities with populations from 500,000 to 1 million. The Wall Street Journal found that homicides increased in 16 of the 20 largest police departments in 2016. Meanwhile, gun murders of police officers are up 68 percent through December 23, compared with the same period in 2015.

What’s Your ‘Public Credit Score’? The Shanghai Government Can Tell You

Rob Scmitz:

The Shanghai city government thinks it can make citizens more honest through a smartphone app. The city released the app, Honest Shanghai, in November during “honesty week,” a celebration of virtuous behavior throughout the city.

Here’s how the app works: You sign up using your national ID number. The app uses facial recognition software to locate troves of your personal data collected by the government, and 24 hours later, you’re given one of three “public credit” scores — very good, good, or bad.

“We want to make Shanghai a global city of excellence,” says Shao Zhiqing, deputy director of Shanghai’s Commission of Economy and Informatization, which oversees the Honest Shanghai app. “Through this app, we hope our residents learn they’ll be rewarded if they’re honest. That will lead to a positive energy in society.”

Shao says Honest Shanghai draws on up to 3,000 items of information collected from nearly 100 government entities to determine an individual’s public credit score.

Universal Basic Income

IGM Booth

Granting every American citizen over 21-years old a universal basic income of $13,000 a year — financed by eliminating all transfer programs (including Social Security, Medicare, Medicaid, housing subsidies, household welfare payments, and farm and corporate subsidies) — would be a better policy than the status quo.
Responses:

Academia’s Broken, so Why Defend Academic Freedom?

Robert Oscar Lopez:

As these five controversies converged in a perfect storm of “academic freedom” controversies, part of me still felt loyal to academia. I had written a long letter (which I still stand by) in defense of Anthony Esolen at Providence College, so I was feeling a little nostalgic for the old view of college as a place to learn about ideas and be exposed to many perspectives. I signed a petition defending one of these professors’ academic freedom.

The response to my comment on the petition was more of what has always made me abhor the left. Try to build bridges to them, and they punish you for it. The history of my disastrous attempt to engage Prof. Potter on the Chronicle of Higher Education is symptomatic of the left’s longstanding history of taking kind gestures from conservatives as a sign that such conservatives are weak. Rather than say, “Wow, what a great chance to speak across party lines,” lefties usually perceive an invitation to shame you publicly, using anything you say against you.

Charters In Madison? Lack Of Governance Diversity To Continue…..

Doug Erickson:

If successful in its bid, the academy would become what’s called an “instrumentality” of the district. It would retain considerable autonomy but receive state education funding and be tuition-free just like any public school. As an instrumentality charter, the School Board would have ultimate governance responsibility and employ the school staff.

The academy’s leaders say the Montessori method would help the district close achievement gaps while expanding options for students who aren’t thriving in conventional schools. The educational approach, developed by Dr. Maria Montessori in the early 1900s, includes multi-age classroom groupings, customized learning plans, uninterrupted blocks of work time, guided choice of work activity, and specially designed learning materials.

The district’s charter school review committee evaluated the school’s initial proposal last summer and fall and found it met preliminary expectations in 10 of 11 areas. However, it fell short in its five-year budget plan.

Members of the charter review committee for the proposal are: Kelly Ruppel, district chief of staff; Nancy Hanks, chief of elementary schools; Alex Fralin, chief of secondary education; and Sylla Zarov, principal of Franklin Elementary School.

Related: a majority of the Madison School,Board rejected the proposed Madison Preparatory IB charter School. This, despite the District’s long term, disastrous reading results.

How to make feminism great again

Christina Hoff Summers:

But less excitable analysts are drawing more sober conclusions: Perhaps the women’s movement is too elitist and out of touch with ordinary citizens, especially working-class women. That seems right, but I would go one step further. Today’s feminism is not merely out of touch with everyday Americans; it’s out of touch with reality. To survive, it’s going to have to come back to planet Earth.

The PC Police Crack Down on . . . Kids Books

Meghan Cox Gurden:

Ranking high among the surrealities of 2016 was the meltdown at a literary festival in Australia when the American-born novelist Lionel Shriver defended the freedom of fiction writers to conjure characters unlike themselves.

“Taken to their logical conclusion,” Ms. Shriver warned, “ideologies recently come into vogue challenge our right to write fiction at all.” Among the concepts she skewered was “cultural appropriation,” the notion that members of one ethnic group mustn’t use (or eat or wear or write about) things emanating from other ethnic groups. The illogical impracticality of the idea, especially with fiction, hasn’t impeded its spread, and the resulting umbrage was a wonder to behold: An Australian writer of Egyptian and Sudanese origin stormed out of the speech, later blaming Ms. Shriver for celebrating “the unfettered exploitation of the experiences of others, under the guise of fiction.” The officials in charge of the event disavowed their keynote speaker’s remarks.

For University Endowments, There’s No Time like the Present

Jane Shaw:

During his presidential campaign, Donald Trump argued that requiring wealthy universities to spend more of their endowment funds on tuition aid would reduce students’ financial burdens.

Whether implementing that idea—which has floated around Congress since 2008—would lower college costs on the whole is doubtful. And, in my view, the federal government is already meddling too much in university policies.

Nevertheless, Trump raised an important issue when he discussed endowment spending at a campaign stop in September. Universities, by hoarding their donations, may not be serving the best interests of students and benefactors.

To unpack this issue, I would like to ask a fundamental question: why do universities have endowments, anyway?

Are Colleges Giving Good Career Advice?

Bryan Dik:

Do U.S. colleges provide students what they need to build successful careers? According to an article in a recent issue of The Atlantic, maybe not. Citing the results of a recent Gallup-Purdue Index study suggesting that just one in six college graduates in the U.S. found their Career Services office to be “very helpful,” the article argues that perhaps colleges should spend fewer resources on attracting inbound students and more on helping existing students establish a meaningful career once they graduate. The poll found that graduates who visit their career center and have a good experience fare better than those who don’t, but the proportion who visit at all is barely more than half. Some students expressed concern that the services they received were too basic, focused primarily on interviewing tips or resume support; others felt there was a mismatch between what they most needed and what they received. “All of this would indicate that there’s room for colleges to improve,” wrote the article’s author, Emily DeRuy, “not only how they connect with students, but also what they offer.”

Most computer science majors in the U.S. are men. Not so at Harvey Mudd

Rosanna Xia

When that first class ended, she signed up for the next level, then another and eventually declared a joint major of computer science and math. Cheering her on were professors who had set out to show her that women belonged in computer science just as much as men did.

It’s a message that goes unheard at many universities. Nationwide, according to the Computing Research Assn., more than 84% of undergraduates who major in computer science are men.

Not so at Harvey Mudd, where more than half — 55% — of the latest class of computer science graduates were women, compared to roughly 10% a decade ago.

Has the Internet Killed Curly Quotes?

Glenn Fleishman

The trouble with being a former typesetter is that every day online is a new adventure in torture. Take the shape of quotation marks. These humble symbols are a dagger in my eye when a straight, or typewriter-style, pair appears in the midst of what is often otherwise typographic beauty. It’s a small, infuriating difference: “this” versus “this.”

Many aspects of website design have improved to the point that nuances and flourishes formerly reserved for the printed page are feasible and pleasing. But there’s a seemingly contrary motion afoot with quotation marks: At an increasing number of publications, they’ve been ironed straight. This may stem from a lack of awareness on the part of website designers or from the difficulty in a content-management system (CMS) getting the curl direction correct every time. It may also be that curly quotes’ time has come and gone.

Insurance firm to replace human workers with AI system

Mainichi:

The insurance firm will introduce an AI system based on IBM Japan Ltd.’s Watson, which according to IBM is a “cognitive technology that can think like a human,” and “can analyze and interpret all of your data, including unstructured text, images, audio and video.” The Watson-based system will be tasked with reading medical certificates written by doctors and other documents to collect information necessary for making payouts, such as medical histories, length of hospital stays, and surgical procedure names.

Education Administrator Consulting Commentary (Humphries, Berquam)

Molly Beck:

“This is a sleazy deal that lets a candidate for public office keep getting paid by taxpayers, with no oversight for how he spends his days,” said Ross. “All the while promoting selling out our public schools to chase campaign cash from the private school voucher industry and the billionaires that support it.”

Humphries said Ross’ comments were “unfortunate.”

“Running for office is quite challenging if you are not independently wealthy and I am making a very serious commitment to this effort while also trying to sustain my family,” he said. “I hope Mr. Ross could recognize this.”

Humphries is one of two candidates backed by conservatives seeking to defeat Evers in his bid for a third term as the head of DPI.

On Regulation And The Law

Jake New:

In 2011, the Department of Education’s Office for Civil Rights issued a Dear Colleague letter that urged institutions to better investigate and adjudicate cases of campus sexual assault. The letter spelled out how the department interprets Title IX of the Education Amendments of 1972, and for the past five years it has been the guiding document for colleges hoping to avoid a federal civil rights investigation into how they handle complaints of sexual violence.

The department’s views were praised by victims and their advocates and led to many changes on college campuses, particularly on the issue of burden of proof when campus judicial systems handle sex assault charges. Republican lawmakers and other critics have argued that the guidance goes farther than just clarifying Title IX. They say the department illegally expanded the gender discrimination law’s scope without going through proper notice-and-comment procedures. At the center of that argument — as well as several recent lawsuits against colleges and the Department of Education — is the lower standard of proof.

The disturbingly accurate brain science that identifies potential criminals while they’re still toddlers

Olivia Goldhill:

Scientists are able to use brain tests on three-year-olds to determine which children are more likely to grow up to become criminals. It sounds like Minority Report come to life: An uncomfortable idea presenting myriad ethical concerns. But, though unnerving, the research is nuanced and could potentially be put to good use.
In the study, published in Nature Human Behavior this week, researchers led by neuroscientists at Duke University showed that those with the lowest 20% brain health results aged three went on to commit more than 80% of crimes as adults. The research used data from a New Zealand longitudinal study of more than 1,000 people from birth in the early 1970s until they reached 38 years old. This distribution, of 20% of a population accounting for 80% of an effect, is strong but not unusual. In fact, it follows the “Pareto principle.” The authors write in their paper:

Low Definition in Higher Education

Lyell Asher:

Every year for nearly a decade, I’ve assigned Anna Karenina to students enrolled in my course on the novel. At more than 800 pages, Tolstoy’s saga can invite hurried reading, so a lot of class time is spent applying the brakes: “Not so fast.” “How do you know that?” “What’s it look like from her point of view?” There’s a useful speed bump in that famous first line: “All happy families are alike; each unhappy family is unhappy in its own way.” In its own way. Don’t assume you know who these people are, Tolstoy cautions, however familiar they may seem.

The book then proceeds to earn that caution, for what follows is a fantastic braid of self-deceptions, mistakes, and misunderstandings, all of which we see (as the characters themselves never can) from Tolstoy’s skybox of omniscience. The knowledge we’re exposed to can often seem too much—not just to take in, but to bear. Karenin’s solemn, impassive reaction to Anna’s tearful declaration of love for Vronsky, for example, seems initially to confirm Anna’s description of her husband as a mechanical functionary for whom time is a schedule and life a series of kept appointments. Only later do we learn that the dead look on Karenin’s face conceals a man so fully alive to his wife’s tears that he had to will himself inert so as not to fall apart. As happens so often in the book, just when we think we finally understand someone, Tolstoy drops a more powerful lens into the scope, or shifts its viewing angle, and we’re bewildered all over again.

HOW DOES YOUR KINDERGARTEN CLASSROOM AFFECT YOUR EARNINGS? EVIDENCE FROM PROJECT STAR

RAJ CHETTY, JOHN N. FRIEDMAN, NATHANIEL HILGER,EMMANUEL SAEZ, DIANE WHITMORE SCHANZENBACH & DANNY YAGAN:

In Project STAR, 11,571 students in Tennessee and their teachers were randomly assigned to classrooms within their schools from kindergarten to third grade. This article evaluates the long-term impacts of STAR by linking the exper- imental data to administrative records. We rst demonstrate that kindergarten test scores are highly correlated with outcomes such as earnings at age 27, college attendance, home ownership, and retirement savings. We then document four sets of experimental impacts. First, students in small classes are signi cantly more likely to attend college and exhibit improvements on other outcomes. Class size does not have a signi cant effect on earnings at age 27, but this effect is imprecisely estimated. Second, students who had a more experienced teacher in kindergarten have higher earnings. Third, an analysis of variance reveals significant classroom effects on earnings.

A Reading Resolution

Christian Kriticos:

I learned more from Isaacson’s biography than I have from a single book in a long time, simply by virtue of the fact that it concerned a subject I previously knew nothing about and assumed I had no interest in. It is a credit to Isaacson that he manages to make the complex evolving world of computer technology so accessible and fascinating to a novice like me; when he concludes that Jobs will be placed “in the pantheon next to Edison and Ford” I can now see where he is coming from, where previously I would have, in my ignorance, snorted in disbelief at the notion.

The reality and mythology of an English major

Stephen Askey:

Once we were mighty. Once we were legion. Once we reigned over colleges and universities like demigods. Well, OK, we English majors were never that important, except maybe in our own eyes. According to a report in the New York Times, degrees awarded in English at American universities fell from seven point six percent of the total in 1971 to three point one percent of the total in 2011 — which goes to show, I suppose, that the golden age was never quite so golden. Still, better the periphery than where we are now — the periphery of the periphery.

One of the less-happy consequences of my decision to major in English 40 years ago is that I haven’t met many (or any) people who share my enthusiasm for the writings of John Dryden. Another is that I make about as much money as a janitor and live in one of the most expensive cities in the world. I knew what I signed up for. My life sentence as an English major has taught me not to care overly much about what are laughingly called “the good things in life.” For better or worse, I can’t look at the glossy advertisements in The New Yorker without a feeling of cognitive dissonance. How could anyone who reads the poems and short stories and criticism in that magazine really want all that crap? If that’s a prejudice, the fault lies in me, not in my discipline, which includes plenty of practitioners with a somewhat more realistic financial outlook than my own. Anyway, for me, it’s less a discipline than a passion. I expect that that beleaguered three point one percent on campuses today feel much the same way. Against the advice of their parents, the social pressure of their peers, and the severely utilitarian direction of American society, they obdurately go on piling up their useless, unremunerative literary courses. See the trouble you get into when you listen to your soul?

Some People’s Brains Are Wired for Languages

Veronique Greenwood:

Babies’ ability to soak up language makes them the envy of adult learners everywhere. Still, some grown-ups can acquire new tongues with surprising ease. Now some studies suggest it is possible to predict a person’s language-learning abilities from his or her brain structure or activity—results that may eventually be used to help even the most linguistically challenged succeed.

In one study, published in 2015 in the Journal of Neurolinguistics, a team of researchers looked at the structure of neuron fibers in white matter in 22 beginning Mandarin students. Those who had more spatially aligned fibers in their right hemisphere had higher test scores after four weeks of classes, the scientists found. Like a freeway express lane, highly aligned fibers are thought to speed the transfer of information within the brain. Although language is traditionally associated with the left hemisphere, the right, which seems to be involved in pitch perception, may play a role in distinguishing the tones of Mandarin, speculates study author Zhenghan Qi of the Massachusetts Institute of Technology.

To save books, librarians create fake ‘reader’ to check out titles

Jason Ruiter

The fictional character was concocted by two employees at the library, complete with a false address and drivers license number.

After allegations by an unidentified person made in November, an investigation by the Lake County clerk of courts’ inspector general’s office concluded that Finley was a fake, and the county has since requested a systemwide audit of its libraries.

The goal behind the creation of “Chuck Finley” was to make sure certain books stayed on the shelves — books that aren’t used for a long period can be discarded and removed from the library system.

On Digital Minimalism

Cal Newport

On the other hand, as a writer I’m often pointing out my dissatisfaction with certain developments of the Internet Era. I’m critical, for example, of our culture’s increasingly Orwellian allegiance to social media and am indifferent to my smartphone.

Recently, I’ve been trying to clarify the underlying philosophy that informs how I think about the role of these technologies in our personal lives (their role in the world of work is a distinct issue that I ‘ve already written quite a bit about). My thinking in this direction is still early, but I decided it might be a useful exercise to share some tentative thoughts, many of which seem to be orbiting a concept that I’ve taken to calling digital minimalism.

Machine Learning Crash Course: Part 1

By Daniel Geng and Shannon Shih:

So what is Machine Learning?

At its core, machine learning is not a difficult concept to grasp. In fact, the vast majority of machine learning algorithms are concerned with just one simple task: drawing lines. In particular, machine learning is all about drawing lines through data. What does that mean? Let’s look at a simple example.

Classification

Let’s say you’re a computer with a collection of apple and orange images. From each image you can infer the color and size of a fruit, and you want to classify the images as either an image of an apple or an orange. The first step in many machine learning algorithms is to obtain labeled training data. In our example, this means getting a large number of images of fruit each labeled as either being an apple or an orange. From these images, we can extract the color and size information and then see how they correlate with being an apple or an orange. For example, graphing our labeled training data might look like something this:

Americans at Work: Urban Farming in West Oakland

Emily Ann Epstein & Alan Taylor:

This week’s Americans at Work essay focuses on inner-city agriculture programs by photographer Preston Gannaway: “Today, about a third of West Oakland residents live in poverty and with food insecurity. It’s a place where most people get their food from McDonald’s, the 99-cent store, or one of the many corner liquor stores. Due to a lack of nutritious food, low-income areas like this one face overwhelming rates of heart disease, obesity, diabetes. In an effort to fill this need, new groups have formed to help combat the neighborhood’s food desert—a term to describe an area where most residents live below the poverty line and a mile or more away from a supermarket.

City Slicker Farms, which formed in 2001 and is one of the most established, recently built a 1.4-acre Farm Park complete with a sliding-scale farm stand and 28-plot community bed. Justin Vandenbroeck runs Fleet Farming Oakland, which constructs small farms in neighborhood yard spaces proclaiming, ‘grow food, not lawns!’ Working an economic angle as well as a dietary one, West Oakland Woods (WOW) Farms formed to help fill an employment need while taking advantage of the changing area’s restaurant boom. WOW operates both a produce and a flower farm that supplies high-end restaurants while training and employing local high-school students with financial need.

But industrial urban areas like West Oakland must also contend with decades of pollutants. The farmers say the soil is too toxic and must be either hauled away or lined to accommodate organic soil beds built on top. Water, soil, and air are all problems in West Oakland, said Vandenbroeck.”

How to Become a Famous Media Scholar: The Case of Marshall McLuhan

Jefferson Pooley:

WHEN MARSHALL MCLUHAN published Understanding Media in 1964, the Cambridge-trained literary scholar was not well known, even inside the academy. By 1967, he was on the covers of Newsweek and the Saturday Review, and the subject of an hourlong NBC documentary, all in the same month. Over three manic years, McLuhan had shot from scholarly obscurity to klieg-lit fame.

Like most celebrity ascensions, McLuhan’s was the product of a conscious publicity campaign. Handlers, press agents, and impresarios worked together to make “McLuhan” a household name. He was packaged and promoted like a promising starlet, with multimedia gusto. Understanding Media garnered a few mainstream print reviews upon publication, but McLuhan’s break came in early 1965, when a pair of San Francisco prospectors — one, Gerald Feigen, a physician, the other, Howard Gossage, an ad-agency executive — “discovered” McLuhan and promptly arranged to visit the Canadian in Toronto. Feigen and Gossage were self-fashioned avant-gardists, using profits from their business consulting firm for “genius scouting”; the doctor read Understanding Media and alerted his partner. Together they plotted a full-fledged publicity rollout, starting with cocktail parties in New York City with media and publishing figures. The pair staged a weeklong “McLuhan Festival” that summer, with nightly parties and a rotating cast of ad executives, newspaper editors, mayoral aides, and business leaders in attendance.

The lesson of Trump and Brexit: a society too complex for its people risks everything

John Harris:

By way of a gloomy seasonal party game, try this. Take the proverbial back of a cereal box, divide it into six rectangles, and on each one, write a supposed cause of the political turbulence now gripping the west: “the financial crash of 2008”, “inequality”, “racism and xenophobia”, “Tony Blair, basically”, and all the rest. Then get out the gin, maybe put on a Radiohead album, and enjoy hours of doom-laden conversational fun.

Were I daft enough to play the game myself, on one rectangle, I think I’d write an explanation so far barely mentioned in the acres of coverage of 2016’s chaos, but one right at the heart of it all: “Ever-increasing complexity, and the diminishing returns it now creates.” It’s not the snappiest conversation starter, I know. But if you’re looking for a grand catch-all theory that ties together Donald Trump, Brexit, and the general sense of a world spinning into chaos, it might not be a bad place to begin.

iPhone Apps Could Be A Revolution In Health — If People Use Them

Stephanie Lee

At the same time, relatively few people took the extra step of doing some of the tasks that the app asked them to do. Just shy of 5,000 people completed a six-minute walk test, a common proxy of heart health, with their phones in hand, according to the study. And while 40,000 people filled out some portion of the app’s health questionnaires, only about 1,300 provided all the information needed to calculate their personalized health risks.

That squares with a recent study that showed that for the first five ResearchKit apps that launched, including MyHeart Counts, the percentage of daily users quickly dropped to 25% or below within the first three months.

“This is a very significant problem with this new form of medical research,” Topol said. “You accrue lots of people, but to keep them engaged, long-term, is perhaps the greatest challenge.” Apps could keep people coming back, he suggested, by offering participants something valuable in return, like personalized insights about their health.

Facebook’s Face Recognition Tech Goes on Trial

Eliza Strickland:

Nimesh Patel, aggrieved user of Facebook and Illinois resident, isn’t naive: He well understands that the social networking company collects information about him. But Facebook went too far for his liking when it collected certain intimate details about his physiognomy, such as how many millimeters of skin lie between his eyebrows, how far the corners of his mouth extend across his cheeks, and dozens of other aspects of his facial geometry that enable the company’s face recognition software to identify him.

Patel is a named plaintiff in a class-action lawsuit against Facebook alleging that the company’s use of face recognition technology violates an Illinois law passed in 2008. The Biometric Information Privacy Act (BIPA) sets limits on how companies can store and use people’s biometric identifiers, which the law defines as fingerprints, voiceprints, retina or iris scans, and scans of hand or face geometry. The case is scheduled for trial this October, and similar Illinois-based lawsuits are proceeding against Google and Snapchat. In the upcoming year, the courts will host a debate over who can keep our faces on file.

The year’s education winners and losers

Alan Borsuk:

Overall, the number of bright spots on the Milwaukee education scene is increasing and there’s more reason for optimism. Someone who has a good handle on these things tried to convince me of this recently.

He made a pretty good case. I’m not exactly giddy — as you will see — but there are promising things happening. I’ve seen more willingness lately in some places to confront issues of quality, both overall and at specific schools. There are some new schools being run by talented leaders. There’s even occasional evidence of less acrimony among those involved in Milwaukee’s sometimes befuddling education landscape.

But when the overall indicators of student success remain generally so troubling — test scores, graduation rates, attendance, suspensions, the gap between kids from have and have-not backgrounds – we still have a crisis.

On that mixed note, I offer some awards for outstanding performance in 2016 in education matters in Milwaukee. In fact, there’s so much to say, I’m going to stretch this into two weeks, so come back next Sunday for more.

Campus Identity Politics Is Dooming Liberal Causes, a Professor Charges

aEvan Goldstein:

The day after the presidential election, Mark Lilla had to get something off his chest. “I wrote in a fever,” he says. The article that resulted, which appeared in The New York Times, argues that “American liberalism has slipped into a kind of moral panic about racial, gender, and sexual identity that has distorted liberalism’s message and prevented it from becoming a unifying force.”

Mr. Lilla, a professor of humanities at Columbia University, pinned the blame, in part, on academe and its fixation on identity politics. “How to explain to the average voter the supposed moral urgency of giving college students the right to choose … gender pronouns?” he asked. “How not to laugh along with those voters at the story of a University of Michigan prankster who wrote in ‘His Majesty’?”

The Crazy Story of the Professor Who Came to Stay—and Wouldn’t Leave

Ian Gordon:

Elizabeth Abel walked up to the front door of her house for the first time in four months and rang the bell. She’d just flown halfway around the world to drop in, unannounced, on the man who’d taken over her home.

When he came to the door, Abel says, the man didn’t seem surprised to see her—or the police officer standing beside her. “Oh, hi,” he said.

Abel peered behind him into her living room, which was practically empty. Most of her furniture was gone: a dining table and four chairs, two easy chairs, an antique piece. Her books and rugs were nowhere to be seen. Even the artwork had been taken off the walls.

As Abel walked around the place she’d called home for three decades, she had the distinct feeling that her life had been erased. In the family room, a small sofa, a table, and a television had been removed. Out on the back deck, the wooden table and benches were missing. The bedrooms were emptied out, her mattresses crammed into the office. Closets were sealed with blue painter’s tape. She turned to the man, who had been renting her place for the past several months—without paying. “What is going on here?” she demanded. “What are you doing?”

US Government Can Legally Access Your Facebook Data (And Now We Know How)

Tyler Durden:

The end of the year is approaching, and data concerning government abuses of power has begun pouring in.

According to Facebook’s Global Government Requests Report, government’s requests for Facebook account data rose 27 percent in the first half of 2016.

Facebook’s official announcement explained that requests for user data went from 46,710 in the last half of 2015 to 59,229 in the first half of 2016. At least 56 percent of these requests, Facebook added, “contained a non-disclosure order that prohibited us from notifying the user.”

Law enforcement agencies from across the globe, Facebook continued, often send restriction requests demanding Facebook remove content from its forums. Fortunately, these requests dropped substantially this year, from 55,827 in the last half of 2015 to 9,663 in 2016 — an 87 percent drop. Most of the 2015 requests revolved around “French content restrictions of a single image from the November 13, 2015 terrorist attacks.”

Additionally, Facebook used its report to disclose for the first time what the company does when law enforcement agencies request “snapshots” of a user account that might be relevant to law enforcement for undisclosed reasons.

Do teachers need to incorporate the history of mathematics in their teaching?

Po-Hung Liu:

This study aimed to reveal the effects of teaching with concrete learning objects taken from the history of mathematics on student achievement. Being a quasi-experimental study, it was conducted with two grade 8 classes in a secondary school located in Trabzon. The experimental group consisted of 27 students and the control group consisted of 25. Data were collected by using worksheets, an achievement exam and written opinion forms. The data from the achievement exam were analysed by using the Mann-Whitney U-test while the data from written opinion forms were analysed through content analysis. The Mann–Whitney U-test results showed a significant difference between the mean ranks of the experimental and control groups in favour of the former. Findings from the written opinion forms suggested that the students found the activities to be instructive and fun, enjoyed using concrete models in their classes, and learned from discovering the rules. It was also found that students had previously not engaged in similar activities and had only experienced the history of mathematics through the life stories and works of mathematicians and the representation of ancient numbers at the beginning of each unit.

Facts about the past and present are either true or false. Can knowledge of the future offer the same degree of certainty?

Tony Sudbury:

So sang Doris Day in 1956, expressing a near-universal belief of humankind: you can’t know the future. Even if this is not quite a universal belief, then the universal experience of humankind is that we don’t know the future. We don’t know it, that is, in the immediate way that we know parts of the present and the past. We see some things happening in the present, we remember some things in the past, but we don’t see or remember the future.

Violence in the Halls, Disorder in the Malls

Heather Mac Donald

Judging by video evidence, the participants in the violent mall brawls over the Christmas weekend were overwhelmingly black teens, though white teens were also involved. The media have assiduously ignored this fact, of course, as they have for previous violent flash mob episodes. That disproportion has significance for the next administration’s school-discipline policies, however. If Donald Trump wants to make schools safe again, he must rescind the Obama administration’s diktats regarding classroom discipline, which are based on a fantasy version of reality that is having serious real-world consequences.

The Obama Justice and Education Departments have strong-armed schools across the country to all but eliminate the suspension and expulsion of insubordinate students. The reason? Because black students are disciplined at higher rates than whites. According to Washington bureaucrats, such disproportionate suspensions can mean only one thing: teachers and administrators are racist. The Obama administration rejects the proposition that black students are more likely to assault teachers or fight with other students in class. The so-called “school to prison” pipeline is a function of bias, not of behavior, they say.

‘Consumer Reports’: FIRE Among Nation’s ‘Best Charities’

FIRE:

Consumer Reports has included FIRE in its recently-released list of the “Best Charities for Your Donation.” The publication chose FIRE as one of its top five, highest-rated Human and Civil Rights charities alongside the American Civil Liberties Union, the Center for Community Change, the Fund for Global Human Rights, and Human Rights Watch.

To compile its list, Consumer Reports compared data from the three major charity watchdogs—CharityWatch, Charity Navigator, and BBB Wise Giving Alliance—to determine the best (and worst) charities in a variety of fields and help consumers “find one that really puts your money to work.”

Civics: High street shops secretly track customers using smartphones

Sarah Knapton:

High street shops including Marks & Spencer are secretly tracking the movements of their customers using their smartphones, it has emerged.

Companies such as footwear supplier Dune, Morrisons and Topshop are among major retailers taking advantage of new technology which picks up the pings emitted by phones as they look for wi-fi networks to join.

The ceilings of many major stores now contain small white receiver boxes which are continuously gathering data.

The shops use the data not only to record the numbers of their customers, but also to see where they move about in the shop, so they can alter the layout to make walking between departments more convenient, or steer customers towards goods they may have missed.
