Economics Job Market

2017-05-09T19:37:38.086+05:30

I first learned about it -- the economics job market which happens during the annual meeting of AEA, the American Economic Association -- from this post by Noah Smith, and I found the whole thing fascinating [I am always interested in disciplinary subcultures -- like the importance of conference papers in Computer Science, or the alphabetical listing of authors in certain disciplines].

But you must listen to this fantastic Planet Money (on NPR) story what this job market does, and how it goes about it -- from the point of view of one of the job applicants (a truly brave soul -- right through the podcast, I was seriously rooting for him!) and of several employers. Absolutely fabulous!

If lack of reproducibility is a crisis, so is lack of producibility

2017-04-17T19:11:56.100+05:30

The accepted practice is instead to adjust the model so that it continues to agree with the lack of empirical support.

This very Zen statement is a part of a commentary by theoretical particle physicist Sabine Hossenfelder-- in Nature, no less (so it must be fashionable, if not also true) -- who writes candidly about the crisis in her field (and its neighbours: astrophysics and cosmology): Science needs reason to be trusted [Caution: paywall]. She calls it a crisis of "overproduction" (i.e., abundance) of theories, but I like to think of it as a crisis of "producibility" of experimental data.

In recent years, trust in science has been severely challenged by the reproducibility crisis. This problem has predominantly fallen on the life sciences where, it turns out, many peer-reviewed findings can't be independently reproduced. Attempts to solve this have focused on improving the current measures for statistical reliability and their practical implementation. Changes like this were made to increase scientific objectivity or — more bluntly — to prevent scientists from lying to themselves and each other. They were made to re-establish trust.

The reproducibility crisis is a problem, but at least it's a problem that has been recognized and is being addressed. From where I sit, however, in a research area that can be roughly summarized as the foundations of physics — cosmology, physics beyond the standard model, the foundations of quantum mechanics — I have a front-row seat to a much bigger problem.

I work in theory development. Our task, loosely speaking, is to come up with new — somehow better — explanations for already existing observations, and then make predictions to test these ideas. We have no reproducibility crisis because we have no data to begin with ... [Bold emphasis added]

Here's something that will makes your jaw not just drop, but go into a tailspin:

In December 2015, the LHC collaborations CMS and ATLAS presented evidence for a deviation from standard-model physics at approximately 750 GeV resonant mass2, 3. The excess appeared in the two-photon decay channel and had a low statistical significance. It didn't look like anything anybody had ever predicted. By August 2016, new data had revealed that the excess was merely a statistical fluctuation. But before this happened, high-energy physicists produced more than 600 papers to explain the supposed signal. Many of these papers were published in the field's top journals. None of them describes reality.

How good are graduate admission interviews, if job interviews are "utterly useless"?

2017-04-17T18:20:29.113+05:30

Faculty members in almost all the Indian institutions are getting ready to interview tens (if not hundreds) of students for a handful (or a few handfuls) of PhD slots in their departments. A recent NYTimes article urges us to be mindful of limitations of this format: The Utter Uselessness of Job Interviews by Jason Dana.

I realize there are quite a few differences between the kind of interviews Dana describes in his article and the kind we use. For example, his "experimental" interviews were (probably) unstructured, while we may be using something more structured [such as probing candidates specifically in the areas / subfields they say they are strong in]. Also, given the overwhelmingly large number of candidates compared to the number of available slots, there's usually a pre-screening exercise which relies on previous academic record, research experience, scores / ranks in entrance exams, etc.

And yet, this article reminds us some of the pitfalls of the interview process.

A 'Special' Resonance

2017-03-29T17:44:14.123+05:30

Resonance, the "journal of science education" published by the Indian Academy of Sciences, had something 'special' in its March issue: as Guest editors Prajval Shastri and Sudeshna Mazumdar-Leighton write in their editorial, "while this issue is no different from any other in intent, it is ‘special’ because it has an all-female authorship."

"Removing Morons from the Productive Flow"

2017-03-27T20:42:03.742+05:30

This profile of Scott Adams, the genius who created the Dilbert comics, has its focus elsewhere (his rationalizations of the rise and rise of Donald Trump during the US Presidential primaries and election), but somewhere in the middle is this gem (in bold, below) [If you are wondering why it stuck a chord, you haven't seen this ... (;-)]:

Adams’s Dilbert empire has been growing for three decades. When he launched the strip in the late ’80s, long-running staples such as Dennis the Menace, Family Circus, and Blondie seemed saccharine and dated. Adams’s creation was fresh, starring a sardonic software engineer named Dilbert; his conceited and grandiose dog, Dogbert; an incompetent boss; and a host of odd co-workers. Early installments showed Dilbert at home. When Adams refocused the strip on the workplace, it caught fire among a generation of office drones who spent their days staring at spreadsheets and slide decks. While workers had long tacked comics like The Far Side and Cathy to their felt cubicle walls, to say something about themselves and their brand of humor, here was a subversive comic about cubicle culture itself. During the ’90s, amid waves of corporate downsizing and the tech boom, a zeitgeisty Dilbert graced the covers of Newsweek, Time, and Fortune. Adams churned out Dilbert-themed calendars, knickknacks, and even a TV show. He also penned op-eds and business tomes, including The Dilbert Principle, based on the theory that companies tend to promote their least competent employees to middle management, “removing morons from the productive flow.”

Update: Wikipedia has an entry on the Dilbert Principle, in case you are interested.

In other words, "Get a Life"

2017-03-20T20:13:39.327+05:30

Very little has been written on jealousy in academic life, and yet, anecdotal evidence suggests that it is prevalent in our profession. This is unsurprising. As Chronicle readers are well aware, academe today is a place of increasingly precarious employment conditions — where the "publish or perish" mantra is more relevant than ever and the pressure to win grant money has reached fever pitch.

In such an environment, it’s little wonder that jealousy can take hold. I’ve certainly felt my share (and I herewith apologize for privately cursing those of you who got positions and/or book contracts that I wanted). Jealousy may come with the academic turf but that’s rarely a good thing. So what can we do to better manage our envy at all stages of the academic career?

That's from Jay Daniel Thompson in The Chronicle of Higher Educationn: Maybe You’re Just a Jealous Academic. Can you spot the understatement of 2017? Hint: it's in bold.

This article eventually gets to "self-help" domain of how to deal with jealousy of the academic kind, and has an advice-list that might help you cope. The last piece of advice? "Develop interests outside the academy." In other words, "Get a Life".

From the Annals of Consumer Complaints: Boring Lectures!

2016-12-05T18:30:11.638+05:30

From The Guardian:

Graduate sues Oxford University for £1m over his failure to get a first
Faiz Siddiqui claims ‘appallingly bad’ teaching during degree course prevented him from having a successful career

An Oxford graduate is suing the university for £1m claiming the “appallingly bad” and “boring” teaching cost him a first-class degree and prevented him from having a successful career.

Faiz Siddiqui, who studied modern history at Brasenose College, told the high court he believes he would have had a career as an international commercial lawyer if he had been awarded a first rather than the 2:1 he achieved 16 years ago.

Whistleblowing is Hard (and Dangerous): Theranos Edition

2016-11-28T19:22:32.361+05:30

Just drop everything and read this absolutely gripping WSJ story on Tyler Shultz, the Theranos whistleblower (who also happens to be the grandson of former Secretary of State George Shultz, who was -- and continues to be -- associated with Theranos).

This snippet is from the section where the lawyers appear:

A few weeks later, Mr. [Tyler] Shultz was confronted by his father after arriving for dinner with his parents at their home in Los Gatos, Calif. His grandfather had called to say Theranos suspected he had talked to the Journal reporter. Theranos’s lawyers wanted to meet with him the next day.

He says he called his grandfather and asked if they could meet without lawyers. The elder Mr. Shultz agreed and invited his grandson to his house. The mood was tense but cordial, Tyler Shultz recalls, and he denied talking to any reporters. He says his step-grandmother was present during the conversation.

His grandfather asked if he would sign a one-page confidentiality agreement to give Theranos peace of mind. According to Tyler Shultz, when he said yes, his grandfather revealed that two lawyers were waiting upstairs with the agreement.

Quotes

2016-10-01T19:06:24.979+05:30

If you are going to use mice in your research, there are all these federal requirements that have to be complied with. [...] And yet, when it comes to your teaching assistant, [there is] no such requirement that you treat them in a humane way. [...] If someone has engaged in sexual harassment, or if someone has discriminated, or if someone is a sexual predator, they should not have access to federal dollars.
-- Congresswoman Jackie Speier.

That quote is from this CNN story on sexual harassment in science that uses Geoffrey Marcy's case in UC-Berkeley as an example. Here's another quote:

... Institutions are incentivised to protect their faculty.
-- Jessica Kirkpatrick, Astrophysicist.

The New Yorker on the Deutche Bank's 10 Billion Dollar Scandal

2016-08-26T21:48:44.160+05:30

As always, we go the extra mile to get you the juiciest of excerpts from the actual story:

Although the bank’s headquarters remained in Germany, power migrated from conservative Frankfurt to London, the investment-banking hub where the most lavish profits were generated. The assimilation of different banking cultures was not always successful. In the nineties, when hundreds of Americans went to work for Deutsche Bank in London, German managers had to place a sign in the entrance hall spelling out “Deutsche” phonetically, because many Americans called their employer “Douche Bank.”

In Memory of Ramesh Mahadevan

I am grateful for this break -- just because it allows me to say a silent "thank you" to my dear friend who is no more. I have lost count of the things he opened my mind to, my eyes to, my ears to. Here's one of them, in a different avatar. He would have enjoyed it too.

"Library of Alexandra"

2016-05-03T18:34:07.725+05:30

Sci-Hub has been making waves. Such huge waves that the AAAS flagship, Science has taken note, with not just one, but three pieces devoted to the website, and its founder, Alexandra Elbakyan. This profile of Elbakyan is quite balanced; it might be because a lot of downloads are by researchers in the rich countries. The third article is an editorial by Marcia McNutt: My love-hate of Sci-Hub.

Here's a WaPo summary, triggered by the revelations in Science. Here's a cool analysis of the Sci-Hub data dump [Edit: here's one more.]

RIP, Ramesh Mahadevan

2016-03-11T14:51:56.867+05:30

Ramesh Mahadevan, a close friend from my grad school days, passed away last night. I'm posting a quick note here to alert some of his friends who are also among this blog's readers.

* * *

His hilarious take on the curious subculture of desi grad students in the US in the 1980s (originally posted at the soc.culture.indian group) earned him a huge fan following. Those of us who had the great fortune to interact with him personally also got to experience his sensitive and compassionate side. Personally, he has been a source of strength ever since we met way back in 1985. I'll miss him a lot.

Ramesh has been mentioned in several posts here. Right at this moment, his website -- mahadevanramesh.net is not working, which is a pity; however, his blog has some of his writing since his return to India.

"... We [the students] ... declare our resistance"

2016-02-29T13:59:21.756+05:30

When I wrote the post on #StandWithJNU yesterday, I was not aware of a petition that students in IISc and NCBS (and, probably, several other institutions) have helped in drafting [I thank Vishu Guttal for the pointer]. The petition is admirably clear, direct and forthright in stating, "By stifling their [Rohith's, Kanhaiya's and other such students'] voices, the government crushes not only the voice of students as a community but of marginalised students in particular. Against this we must collectively stand, and declare our resistance."

Also worth noting: the petition is available in many Indian languages.

Read the petition, and sign it if it speaks to you. [I have signed it, and I see several familiar names in the list of signatories.] Also, please do share it with others you know.

#StandWithJNU

2016-02-28T20:28:56.201+05:30

These are depressingly bad times for higher ed institutions in India. If administrators were the victims of authoritarian excess in iconic institutions such as IIT-D and ISI-Kolkata, they also seem to be complicit in dishing it out to students at other iconic institutions such as IIT-M, University of Hyderabad and Jawaharlal Nehru University. Politicians (even "responsible" ones such as central ministers) and news anchors throw the "anti-national" mud indiscriminately at students [sometimes with such epic ineptitude -- which would be funny if only lives and reputations were not at stake]. Kafila and Smoke Signals [Prem Panicker's blog] have been my go-to places for updates on the terrible travesty that has been playing out in Delhi and elsewhere in the country. These troubled times also offer an opportunity to learn more about nationalism and its discontents (one of whom is a Bharat Ratna!). Also about dissent, free speech, their limits. And about universities, their mission. Here are some links that have educated me on these and related issues. Siddharth Varadarajan: On Kanhaiya: It is Time to Stand Up and Be Counted. Sangeeta Dasgupta: Umar Khalid, My Student. Amitava Kumar: Hounding students is pest control? Big ‘mishtake’. Christina Daniels' response to a speech by HRD Minister in the Lok Sabha. It includes a punchy quote [“Politicians are not born; they are excreted.”] and an insightful one [“Orators are most vehement when their cause is weak.”] -- both from Cicero! And a totally doctored video featuring Kanhaiya Kumar. Some more: C.P. Surendran: India will pay for Arnab Goswami and Swapan Dasgupta's nationalism. Gopalkrishna Gandhi: In Defence of Mother India, Students’ Movement Takes Charge. Tunku Varadarajan: Reverse Swing: The BJP versus the jholawala. Lawrence Liang: Ultra-nationalists make light of patriotism. Here's an excerpt where he quotes Mahatma Gandhi: In contrast to the knee-jerk declaration that any criticism of the government or the state is necessarily seditious speech, let’s not forget that Mahatma Gandhi had been tried under the same provision (Sec. 124-A) in 1921 for an article that he had published in Young India. In his statement on March 18, 1922 before Judge Broomfield, Gandhiji famously asserted: “Section 124-A, under which I am happily charged, is perhaps the prince among the political sections of the Indian Penal Code designed to suppress the liberty of the citizen. Affection cannot be manufactured or regulated by law. If one has no affection for a person or system, one should be free to give the fullest expression to his disaffection, so long as he does not contemplate, promote, or incite violence.” Gandhi was prescient in his sharp legal understanding of the provision and it is not surprising that his interpretation of the law is what the Supreme Court in the postcolonial context has also reiterated, consistently holding that mere words and criticism do not qualify for sedition and it has to be accompanied by an incitement to imminent violence. [...] [...]
