Last year I was fortunate to get to work with a new team of co-authors on a paper titled “Quantifying minimum mobility needs: the Who, the Where, and the Why.” The project afforded a little space to think about the concept of wellbeing, in particular how it relates to mobility, and to engage with some fascinating early literature on fundamental human needs.

This is a new kind of post for me, in which I'll share some commentary or spare thoughts on this paper. These are links and connections to other topics, authors, and ideas that didn't fit into the paper …

This post expands on some text from the README of iam-units, in order to illustrate some improved ways to structure data and metadata. These are especially helpful in systems research, where data from multiple disciplines/domains/contexts are often combined.

iam-units is a thin wrapper around the very useful pint, that I wrote with some colleagues to handle unit conversions for data from integrated assessment models (IAMs) of energy and climate, including global warming potential (GWP) conversions between greenhouse gas (GHG) species:

In [1]: from iam_units import registry, convert_gwp

# Use a pint.UnitRegistry to convert from one unit to another …

In research with global scope and country- or country-group resolution, it's common to handle data with one or more [1] dimension(s) identifying a country (countries) for each observation. Problems can arise when inconsistent identifiers—“United States” vs. “United States of America”—are used to label this dimension, either across different data sets, or within one data set.

The best precaution against these problems is to convert idiosyncratic identifiers to short, standard ones, as soon as possible. ISO 3166 alpha-2 or alpha-3 codes (CA or CAN for Canada) are a natural choice for standard identifiers. [2]

Family and friends in Canada and the United States have asked about my situation here in Vienna during the COVID-19 pandemic. This post is for you; I might write another, wonkier one that focuses more on science, (mis)information, and policy.

First things first: I'm fine!

As a Technology & Policy Program student, you need to prepare a research thesis for your S.M.; if you're in another MIT graduate program, you will likely also need to prepare a thesis or academic publication at some point during your degree!

Why? Compared to Microsoft Word, the LaTeX document preparation system can save you considerable time in writing your thesis, as well as other documents such as academic publications and the writing assignments for Science, Technology, and Public Policy. At the same time, the results will be more elegant, readable, reusable, and reproducible. STPP coursework is a great opportunity …

Bloomberg reports:

Xin Guobin, the vice minister of industry and information technology [MIIT], said the government is working with other regulators on a timetable to end production and sales [of fossil-fuel powered vehicles]. The move will have a profound impact on the environment and growth of China’s auto industry, Xin said at an auto forum in Tianjin on Saturday.

This is, no doubt, a major announcement. China is the world's largest market for light-duty vehicles (LDVs; cars and light trucks), so the impact will be greater than that of earlier statements from governments in the UK and France. On …

I use LaTeX for my academic work. For some time Atom has been my editor of choice. Over the years, I've migrated through a variety of workflows, including using dedicated editors like LyX to write my S.M. thesis.

Atom is not a dedicated LaTeX editor, but it is immensely popular. Consequently it has many useful features and packages that I've found improve my productivity for writing code (LaTeX documents are, after all, code).¹ Some of these are LaTeX-specific, but many are not.

See previous writing on this use-case by Matteo Merola and others.

This is the first time I've seen, in person or a photograph, a poster or billboard containing only a QR code—with no accompanying text.¹ The code contains a link to this clip from Charlie Chaplin's The Great Dictator (1940):

Cansplain (v): (not to be confused with mansplain)

1. to nicely explain something about the United States, to Canadians;
2. vice versa.

Within minutes of one another, two people asked me to cansplain executive orders. Donald Trump is signing a lot of these, and people are distressed because they're seeming to do all kinds of terrible things. What are they?

You could, of course, read Wikipedia. Here's a fast-and-loose version.

Bureaucracy

Most of the work of government happens in a bureaucracy that's organized into units that I will call ‘departments’. There are some important differences:

I often feel that I spend too much time engaged in online political discussion. As I do, I'm aware that this likely does little to change political outcomes—who gets elected, and what policies they pursue—that concern me and drew me to those discussions in the first place. This is because:

1. I am stuck in my own communities of like-minded people, and
2. Any other person who stumbles across my posts and comments is unlikely to be swayed by reading them, no matter the tone.

All this said, I still try my best to enter or start discussions that help …

Echoing Robert Stavins, I have only a narrow area of expertise,¹ and it does not include political science. I know that some of the following turns on empirical questions that can be answered with data and rigorous analysis, and that there are researchers trying to do just this. I should, and will, acquaint myself with the knowledge they have produced; but that will be a gradual project.

In the meantime, I and others need to make decisions about how to get by in a world that seems, suddenly, different from the one some thought we lived in. We each …

My American friends, and friends in America,

Think about your neighbours—women, the poor, immigrants, Muslims, Latinos, queers, trans people, and others. Think of the people in other countries who depend on U.S. aid, diplomacy and action for their survival or security—including from the threat of climate change. Think of their faces and their names. (If you don't know their names, resolve to learn them.)

You may be tired after a 20-month campaign. They are, too. You may wish you could have a break, to recover yourself and your equilibrium. They won't get one. Trump, and the worst …

Pokémon GO is sweeping the world, and generating a lot of interesting headlines. Here's one:

Holocaust Museum to visitors: Please stop catching Pokémon here

Reactions to this—and other stories of Pokémon trainers falling into empty swimming pools, invading their neighbours' back yards, and committing other faux pas—varied. Some joked and punned, while one indignant Facebook commenter demanded to know, "Who gave them [Nintendo & Niantic, the game's creators] the right to impose AR [augmented reality] there?" (emphasis added)

Implicit in the phrasing of this remark is the idea that one has a right to control AR content associated^{1 …}

"Salvation or Menace" by Chris Turner in The Walrus

This is all definitely cause for optimism, especially the degree of agreement among panelists. I was nearly dumbstruck yesterday to read about Patrick Brown stating plainly to the PC Party of Ontario that "Climate change is a fact, It is a threat. It is man made. We have to do something about it, and that something includes putting a price on carbon."

My worry about proxy wars of all kinds is that it is not simply a matter of collective choice to avoid them. Energy East, for instance, must come before …

I view my teaching as a process of continual development, in which I seek to become more able to create authentic experiences for my students; respond flexibly to their needs; judiciously incorporate new technology, techniques and research; and convey to them my passion for the topics I choose to teach.

Continual development

My graduate student teaching is in the areas of engineering & public policy, and engineering leadership development;¹ my undergraduate teaching includes these areas and also fundamentals of engineering analysis. I am familiar with and appreciate many of the criticisms of “traditional” engineering education in Canada and the United …

Following the good advice of an instructor from last term, I am resolving for 2015 to write for 15 minutes every day!

To be precise, the advice was to write material with a non-zero probability of appearing in my thesis. I realized that I already do spend more than 15 minutes writing each day, but without much focus. Instead, I comment in various places, or write blurbs to frame articles and other links shared on Facebook.

Though I probably spend more time on these non-research-related words than I should, that doesn't make them valueless. In fact, I usually choose to …

Lest we be paralyzed with indecision, we confidently go about our everyday lives making assumptions, reasoning from the few to the many, seeking regularity and choosing, optimistically, to interpret the outcomes of our decisions as confirmation that our haphazard approach was the best one. What's more, we do the same—and eagerly accept arguments developed in the same way—when we aim to digest current events and important societal trends.
