What is cultural appropriation?

The problem isn’t that cultures intermingle, it’s the terms on which they do so and the part that plays in the power relations between cultures. The problem isn’t “taking” or “borrowing”, the problem is racism, imperialism, white supremacy, and colonialism. The problem is how elements of culture get taken up in disempowering, unequal ways that deny oppressed people autonomy and dignity. Cultural appropriation only occurs in the context of the domination of one society over another, otherwise known as imperialism. Cultural appropriation is an act of domination, which is distinct from ‘borrowing’, syncretism, hybrid cultures, the cultures of assimilated/integrated populations, and the reappropriation of dominant cultures by oppressed peoples.

Aircraft Carriers in Space

An article about naval metaphors in fictional space warfare. Sometimes I suspect that I like science fiction meta way more than I like science fiction.

“I’m not like the other girls.”

A quote I saw making the Tumblr rounds, which said, “I’m not like other girls!” It went on to avow wearing Converse instead of heels, preferring computer games to shopping, so on and so forth. When I saw it, about 41,000 girls had said they weren’t like “the others.”

Is Australia in Danger of Becoming Greece? Austerity and Blackmail Down Under

It is not enough to respond to this ongoing rhetoric about Australia’s supposed calamitous future by pointing out, as Ms Gillard correctly did, that these comparisons are ridiculous given the state of European periphery countries. Yet the ideological blackmail is strangely telling, precisely because the financial sector in the form of the troika (the International Monetary Fund, the European Commission and the European Central Bank) has held Greece’s politicians hostage, forcing a slashing of the government in exchange for “bail-out” loans.

The Start-to-Hate Review System

The concept is simple: Rate media based on how long it takes to encounter something bigoted. The longer it takes, the better the media.

An Investigation Into Xinjiang’s Growing Swarm of Great Gerbils

I am subscribed to two “long form” websites: the picks of Long Reads, which focuses on newer pieces, and the editor’s picks of Longform, which tend to skew a little older. Hence, this, from McSweeny’s in January 2005. I always like a piece that clearly ended up not being about what the original pitch was about. In this case, the writer wanted (or supposedly wanted, I guess) to investigate a gerbil plague, and ended up writing an article about gerbil social structures, text messaging on Chinese phone networks, and, several times, the Black Death. Which is how I ended up reading Wikipedia articles about pandemics the same night I was getting sick with the first illness I’ve had since I got out of hospital.

Mariana Trench Explosion

I think of Randall Munroe as a science writer who happens to be funded by merchandise sales from a comic. I don’t regularly look at the comic any more but I follow his blag and his What If? Answering your hypothetical questions with physics, every Tuesday writing more closely. This What If? is one of my favourites to date, although it’s hard to beat the first one. However, this one features an excursion into unpublished work by Freeman Dyson. SO HARD TO CHOOSE.

Do bicycle helmets reduce head injuries?

It’s impossible to follow Liam Hogan on Twitter without becoming interested in urban transport issues. At the moment the big conversation is helmet laws in Australia, which are arguably interfering with take-up of bike share schemes (if you’re going to have to get hold of a helmet, you don’t just jump on the bike, hence, scheme falls apart), although see Why is Brisbane CityCycle an unmitigated flop? for several other reasons that scheme may be failing.

Anyway, this one: A new study reports the rate of hospitalisations for cycling-related head injuries in NSW has fallen markedly and consistently since 1990. The authors say it’s due to helmets and infrastructure.

The drugs don’t work: a modern medical scandal and Ben Goldacre: ‘It’s appalling … like phone hacking or MPs’ expenses’

Reboxetine is a drug I have prescribed. Other drugs had done nothing for my patient, so we wanted to try something new. I’d read the trial data before I wrote the prescription, and found only well-designed, fair tests, with overwhelmingly positive results. Reboxetine was better than a placebo, and as good as any other antidepressant in head-to-head comparisons… In October 2010, a group of researchers was finally able to bring together all the data that had ever been collected on reboxetine, both from trials that were published and from those that had never appeared in academic papers. When all this trial data was put together, it produced a shocking picture. Seven trials had been conducted comparing reboxetine against a placebo. Only one, conducted in 254 patients, had a neat, positive result, and that one was published in an academic journal, for doctors and researchers to read. But six more trials were conducted, in almost 10 times as many patients. All of them showed that reboxetine was no better than a dummy sugar pill. None of these trials was published. I had no idea they existed.

Given that I favourited two separate articles about this, I’m going to buy the book. Now you know.

Going blind? DRM will dim your world

[I]t turned out I needed Adobe Digital Editions to ‘manage my content’… It tried, of course, to force me to give Adobe my email and other details for the ‘Adobe ID’ that it assured me I needed to get full functionality. I demurred… and was confronted by a user interface that was tiny white text on a black background. Unreadable. Options to change this? If they exist, I couldn’t find them.

Getting this far had taken me half an hour fighting my way through a nest of misery and frustration with broken eyes and a sinking heart. Along the way, I’d been bombarded by marketing messages telling me to “enjoy the experience” and “enjoy your book”.

Reader, I wept. Marketing departments, here’s a top tip: if your customer is reduced to actual, hot, stinging tears, you may wish to fine-tune your messaging.

5 Plans to Head Off the Apophis Killer Asteroid

Friday the 13th of April 2029 could be a very unlucky day for planet Earth. At 4:36 am Greenwich Mean Time, a 25-million-ton, 820-ft.-wide asteroid called 99942 Apophis will slice across the orbit of the moon and barrel toward Earth at more than 28,000 mph. The huge pockmarked rock, two-thirds the size of Devils Tower in Wyoming, will pack the energy of 65,000 Hiroshima bombs–enough to wipe out a small country or kick up an 800-ft. tsunami.

On this day, however, Apophis is not expected to live up to its namesake, the ancient Egyptian god of darkness and destruction. Scientists are 99.7 percent certain it will pass at a distance of 18,800 to 20,800 miles… Scientists calculate that if Apophis passes at a distance of exactly 18,893 miles, it will go through a “gravitational keyhole.” This small region in space–only about a half mile wide, or twice the diameter of the asteroid itself–is where Earth’s gravity would perturb Apophis in just the wrong way, causing it to enter an orbit seven-sixths as long as Earth’s. In other words, the planet will be squarely in the crosshairs for a potentially catastrophic asteroid impact precisely seven years later, on April 13, 2036.

It turns out that with current technology we might be able to move the asteroid prior to the (potential) 2029 entry into the gravitational keyhole, but if it did so we would be unlikely to perturb the orbit sufficiently after that point to avoid a civilisation-ended impact. So it’s the question of how many resources to spend on a low-probability but enormously catastrophic event.

Sunday Spam: toast and vegemite

This week, I feel the need to emphasise that linking does not imply uncritical endorsement!

Philip Roth and Wikipedia

There’s only one problem with this: Roth’s open letter is at best the (justifiably) aggrieved and confused ramblings of a man ignorantly discussing what he does not understand or remember, and at worst a deliberately malicious act inspired by nothing more than a misguided desire to flip us the Vs and maybe get paid by the New Yorker on the way.

In Response to Amanda Palmer

Is it noble to volunteer for a cash-rich for-profit enterprise? And what about when taking the gig means that you’re taking food from the mouths of people whose day job it is to play these kinds of high-pressure, high-profile concerts and ensure that the audience won’t be let down?

Is it noble to devalue the role of musicians by suggesting that their years of training and their tens of thousands of hours of practice is worth little more than a beer and a high-five?

Headspace withdraws support for RU OK? Day

In a statement released this afternoon, the organisation said it was uncomfortable about the support RU OK? Day was receiving from Gloria Jean’s because of the coffee chain’s $30,000 donation to the Australian Christian Lobby (ACL).

Girls gone Wilder

Rose Wilder Lane’s life story is arguably way more interesting than that of her mother, Laura Ingalls Wilder.

Owen Jones: William Hague is wrong… we must own up to our brutal colonial past

As India became increasingly crucial to British prosperity, millions of Indians died completely unnecessary deaths. Over a decade ago, Mike Davis wrote a seminal book entitled Late Victorian Holocausts: the title is far from hyperbole. As a result of laissez-faire economic policies ruthlessly enforced by Britain, between 12 and 29 million Indians died of starvation needlessly. Millions of tons of wheat were exported to Britain even as famine raged. When relief camps were set up, the inhabitants were barely fed and nearly all died.

Philosophy gender war erupts after call for larger role for women

It began with a private email last month from one established male philosopher to four others: Proceed with a Berlin-based conference that features 14 male speakers and no women, the writer said, and I will essentially launch a campaign to take you down professionally.

How Google Builds Its Maps—and What It Means for the Future of Everything

Or as my friend and sci-fi novelist Robin Sloan put it to me, “I maintain that this is Google’s core asset. In 50 years, Google will be the self-driving car company (powered by this deep map of the world) and, oh, P.S. they still have a search engine somewhere.”

Legal myths about the Assange extradition

Whenever the Julian Assange extradition comes up in the news, many of his supporters make various confident assertions about legal aspects of the case.

Some Assange supporters will maintain these contentions regardless of the law and the evidence – they are like “zombie facts” which stagger on even when shot down; but for anyone genuinely interested in getting at the truth, this quick post sets out five common misconceptions and some links to the relevant commentary and material.

The Joke’s on You

[Jon] Stewart and [Stephen] Colbert, in particular, have assumed the role of secular saints whose nightly shtick restores sanity to a world gone mad.

But their sanctification is not evidence of a world gone mad so much as an audience gone to lard morally, ignorant of the comic impulse’s more radical virtues. Over the past decade, political humor has proliferated not as a daring form of social commentary, but a reliable profit source. Our high-tech jesters serve as smirking adjuncts to the dysfunctional institutions of modern media and politics, from which all their routines derive. Their net effect is almost entirely therapeutic: they congratulate viewers for their fine habits of thought and feeling while remaining careful never to question the corrupt precepts of the status quo too vigorously.

Pawns in the War on Drugs

Informants are the foot soldiers in the government’s war on drugs. By some estimates, up to eighty per cent of all drug cases in America involve them, often in active roles like Hoffman’s. For police departments facing budget woes, untrained C.I.s provide an inexpensive way to outsource the work of undercover officers. “The system makes it cheap and easy to use informants, as opposed to other, less risky but more cumbersome approaches,” says Alexandra Natapoff, a professor at Loyola Law School in Los Angeles and a leading expert on informants. “There are fewer procedures in place and fewer institutional checks on their use.” Often, deploying informants involves no paperwork and no institutional oversight, let alone lawyers, judges, or public scrutiny; their use is necessarily shrouded in secrecy.

Gyms and personal training

So I have a dilemma with exercise that I suspect a lot of people share: I’d ultimately like to have access to the facilities that many gyms offer, both the weights and the exercise classes, but the whole surrounding consumer setup is completely offputting to me.

First of course is the price structure, where they take money whether or not I use the gym. Smooth, gyms, smooth. (Yes, I am aware that they make more money — I assume far more, given how bad it is for customer perceptions of their industry — that way. But I am not interested in gyms’ profitability, in capitalism I highly value my right to be an utterly selfish consumer in that respect.) So, yeah. Is my (realistically) once-a-week-with-occasional-skips use of a gym worth $30 a week to me? No.

Assuming I got past that, here’s what needs to happen, for example, for me to join Ian Thorpe Aquatic Centre’s gym, which is most likely because I’d like access to their pool rather than paying for a gym and a pool. First, I need to go there with my husband, because it would be a joint membership. OK, there go about ninety-five percent of my trips there. Secondly, my husband must either not be in a hurry to get back to work, or we must not have our bored toddler fussing at us. So, that’s the remaining five percent of trips. Then, once I did sign up, there’s compulsory personal training sessions focusing on my fitness goals. I can’t think of anything I find less inspiring, than to discuss my fitness goal “I enjoy moving my body sometimes” with people who are trained to equate fitness goals with either “I want to achieve top percentile cardiovascular or strength performance” or “I want to lose a fair chunk of weight”. I rather suspect this mismatch is deliberate too, because there’s no better customer than one who has been persuaded that they really need to keep this gym membership… for the far-away day that the sense of being too inferior a body to use the gym goes away.

The Myth of Looming Female Dominance

[One] should always be wary of raw numbers in the news. In fact, when you look at the trend as published by the Census Bureau, you see that the proportion of married couple families in which the father meets the stay-at-home criteria has doubled: from 0.4% in 2000 to 0.8% today. The larger estimate which includes fathers working part-time comes out to 2.8% of married couple families with children under 15. The father who used the phrase “the new normal” in [the NYT story] was presumably not speaking statistically.

Miley Cyrus haircut shocker: Short hair isn’t a cry for help

So just to remind you: A young woman changing her look in a way that doesn’t scream, “Please, world, love me because I am a Victoria’s Secret model,” right now, in the year of our Lord 2012, freaks people out. It actually makes them wonder if she’s lost her mind.

Scientists Claim To ‘Block’ Heroin, Morphine Addiction: One Skeptic’s Reaction

THe “one skeptic’s reaction” is actually along the lines of “this is very interesting research, that appears to have not much application to blocking existing addiction, but might to making opiates more effective for pain while being less addictive.”

Tribalism and locavorism

Why does the idea of “food miles” bug (some) freemarketeers while (some) environmentalists resist evidence that it’s not environmental friendly? This appears to be against both their stated ideological positions.

Why Aren’t Female Ski Jumpers Allowed in the Olympics?

Dating to the 2010 Winter Olympics.

The International Olympic Committee (IOC) says the women’s exclusion isn’t discrimination. President Jacques Rogge has insisted that the decision “was made strictly on a technical basis, and absolutely not on gender grounds.” But female would-be Olympic competitors say they don’t understand what that “technical basis” is. Their abilities? They point to American Lindsey Van, who holds the world record for the single longest jump by anyone, male or female.

The foibles of flexibility

Since the average age of those studying for a PhD is 37 most of you will have some kind of family commitment, and yes – pets count. I find it mystifying that so many of the ‘how to get a PhD’ books offer precious little advice on how to cope.

Am I Black Enough For You?

I watched this case unfold with particular interest. Why? Because I am married to an Aboriginal man and I have an Aboriginal daughter (they are of the Ngarigo people and the Gunditjmara people). And my daughter has fair skin, dark blond/light brown hair and very blue eyes. She is one of these “white Aboriginals” that Andrew Bolt decries.

We’re not here for your inspiration

And there’s another one of a little boy running on those same model legs with the caption, “Your excuse is invalid”. Yes, you can take a moment here to ponder the use of the word “invalid” in a disability context. Ahem.

Then there’s the one with the little girl with no hands drawing a picture holding the pencil in her mouth with the caption, “Before you quit. Try.”

I’d go on, but I might expunge the contents of my stomach.

Let me be clear about the intent of this inspiration porn; it’s there so that non-disabled people can put their worries into perspective. So they can go, “Oh well if that kid who doesn’t have any legs can smile while he’s having an awesome time, I should never, EVER feel bad about my life”. It’s there so that non-disabled people can look at us and think “well, it could be worse… I could be that person”.

Sunday Spam: bagels, lox and smoked salmon

In belated honour of my breakfast in New York, Sunday July 8.

Baby Loss and the Pain Olympics

Warning for baby loss discussion.

I really have to question why seeing someone else processing their emotions is her pet peeve.

Do I believe a miscarriage and neonatal death is the same thing — of course not. If they were the same thing, they would share the same term. But just because I see them as apples and oranges doesn’t mean that I don’t also see them as fruit. They are both loss.

The deadly scandal in the building trade

Readers would not guess from the “national conversation” that the construction industry is sitting on a story as grave in its implications as the phone-hacking affair – graver I will argue. You are unlikely to have heard mention of it for a simple and disreputable reason: the victims are working-class men rather than celebrities… The construction companies could not be clearer that men who try to enforce minimum safety standards are their enemies. The files included formal letters notifying a company that a worker was the official safety rep on a site as evidence against him.

On Technical Entitlement

By most measures, I should have technical entitlement in spades… [and yet] I am very intimidated by the technically entitled.

You know the type. The one who was soldering when she was 6. The one who raises his hand to answer every question–and occasionally try to correct the professor. The one who scoffs at anyone who had a score below the median on that data structures exam (“idiots!”). The one who introduces himself by sharing his StackOverflow score.

Puzzling outcomes in A/B testing

A fun upcoming KDD 2012 paper out of Microsoft, “Trustworthy Online Controlled Experiments: Five Puzzling Outcomes Explained” (PDF), has a lot of great insights into A/B testing and real issues you hit with A/B testing. It’s a light and easy read, definitely worthwhile.

Selected excerpts:

We present … puzzling outcomes of controlled experiments that we analyzed deeply to understand and explain … [requiring] months to properly analyze and get to the often surprising root cause … It [was] not uncommon to see experiments that impact annual revenue by millions of dollars … Reversing a single incorrect decision based on the results of an experiment can fund a whole team of analysts.

When Bing had a bug in an experiment, which resulted in very poor results being shown to users, two key organizational metrics improved significantly: distinct queries per user went up over 10%, and revenue per user went up over 30%! …. Degrading algorithmic results shown on a search engine result page gives users an obviously worse search experience but causes users to click more on ads, whose relative relevance increases, which increases short-term revenue … [This shows] it’s critical to understand that long-term goals do not always align with short-term metrics.

Angels & Demons

One of the various Longform collections, and like many of them, a crime piece:

On June 4, 1989, the bodies of Jo, Michelle and Christe were found floating in Tampa Bay. This is the story of the murders, their aftermath, and the handful of people who kept faith amid the unthinkable.

On Leaving Academia

As almost everybody knows at this point, I have resigned my position at the University of New Mexico. Effective this July, I am working for Google, in their Cambridge (MA) offices.

Countless people, from my friends to my (former) dean have asked “Why? Why give up an excellent [some say 'cushy'] tenured faculty position for the grind of corporate life?”

Honestly, the reasons are myriad and complex, and some of them are purely personal. But I wanted to lay out some of them that speak to larger trends at UNM, in New Mexico, in academia, and in the US in general. I haven’t made this move lightly, and I think it’s an important cautionary note to make: the factors that have made academia less appealing to me recently will also impact other professors.

Ethics, Culture, & Policy: Commercial surrogacy in India: A $2 billion industry

Since its legalization in 2002, commercial surrogacy in India has grown into a multimillion-dollar industry, drawing couples from around the world. IVF procedures in the unregulated Indian clinics generally cost a fraction of what they would in Europe or the U.S., with surrogacy as little as one-tenth the price. Mainstream press reports in English-language publications occasionally devote a line or two to the ethical implications of using poor women as surrogates, but with few exceptions, these women’s voices have not been heard.

Sociologist Amrita Pande of the University of Cape Town set out to speak directly with the “workers” to see how they are affected by such “work.”

Meet the Ada Initiative: supporters party, San Francisco, Mon July 16

I’m in the US for a couple of weeks. The Ada Initiative, my non-profit organisation supporting women in open technology and culture, is having a party while I am there:

We invite you to join us in downtown San Francisco for an informal meetup! Ada Initiative co-founders Mary Gardiner and Valerie Aurora will be there, along with many of our board members and advisors. Mary is visiting San Francisco on her way back from keynoting the Wikimania conference, and wants to meet as many Bay area Ada Initiative supporters as she can.

Date: Monday July 16
Time: 7:30pm to 9:00pm

This is a self-hosted gathering at Jillian’s, a restaurant and bar in the Metreon.

Jillian’s
101 4th St
San Francisco, CA 94103
USA

Please register so we know how many people to expect.

We thank anyone who takes this opportunity to donate, but this gathering is open to everyone who supports women in open technology and culture in any manner.

Valerie and I are also having lunch on the Google Mountain View campus the following day (Tues Jul 17) in order to meet supporters there. It’s only open to Googlers and their invited guests though. Send an email to contact@adainitiative.org if that describes you, you want to come, and you haven’t yet heard about this.

If you know me personally, and you didn’t know that I am in DC all this week and San Francisco for half of next week, send me an email at the usual address and we might meet up.

On opting out

Captain Awkward has a thread on lateness and keeping in contact with people who are constantly late or no-shows. Her answer is worth reading, because she takes both sides seriously: the way being late feeds into anxiety or depression disorders sometimes (and has for her), and the way to structure social engagements with people who are in that place (whether due to mental health issues or not, it doesn’t require disclosure).

She’s specifically asked that people who are good with time and todo lists (I am, relatively) not drop in with “handy hints”, which is fair enough, but now I’m finding some of the”just loosen up, I have rejected our culture’s terrible clock ticking obsession, and I think that makes me a better person” (uh, paraphrased) comments irritating. I’m posting here rather than there because of the relative privilege of being good with my culture’s approach to time, though.

However, opting out is also a pretty privileged thing to do, honestly. Here’s the big clock related things I can’t opt out of, right now: my son’s childcare, who (like most) fine about $1 a minute for late pickups. Moreover, those people also have children to pick up and errands to run, so a significantly late arrival from me would ruin at least three families’ evenings. (Two staff members are required on premises at all times, so one late parent is two late workers.)

Parenting is by no means the only type of problem here too (look at some writings on spoon budgeting some time: what happens when you are an hour late for someone who set aside spoons to see you?) but it’s a pretty typical set of examples. So are people who work in a great number of jobs, especially low pay and insecure jobs.

You can be over-scheduled in a privileged way (racing from piano lessons to dinner parties), but you can be over-scheduled without that (racing from end of shift to the hard childcare deadline to the hospital’s visiting hours to the mechanics for the 6th car repair this season), too. So, I find it difficult to respond to a fairly simple analysis of “I figure that half an hour doesn’t matter that much, or shouldn’t! We all survived before mobile phones [or clocks]! Just say no!” When your needs are dictated by other people armed with clocks and mobile phones, there may not be an exit sign visible.

There are a lot of living cultures with looser time constraints than the one I live in. (People talk about a “polychronic-monochronic” axis of cultures, which Wikipedia tells me is due to the anthropologist Edward Hall.) There are ways to systemically structure things so that half an hour doesn’t matter that much. But, when you don’t live in such a culture or can’t stay in one, it’s just not that easy. But when is “just say no” ever the solution to anything serious?

Paul Offit’s Vaccines course

People in my research group have been understandably excited about, eg, Andrew Ng’s online machine learning course (you can also do Natural Language Processing with Dan Jurafsky and Chris Manning, respectively co-authors of Speech and Language Processing and Foundations of Statistical Natural Language Processing, so you need never choose between NLP textbook authors again).

Since submitting my PhD — I never mentioned that here, sorry, but if you follow me anywhere else you’ve probably heard! It’s under examination presently — I’ve zoned out some and eventually decided to head on over to Coursera and see what was on offer, in case I went two weeks without computer science and had withdrawal I guess. There’s nothing that exactly lines up with my desired enrollment dates right now, so instead, I’m in Paul Offit’s Vaccines course, starting June 25. Looking forward to it! Apparently there will be “challenging” assessment quizzes: I’m hoping to write up anything particularly interesting that comes up in the course, although I suspect that for people familiar with Offit’s various books and lectures (I’m not) it may be something of a repeat.

Note: never say never I guess, but anti-vax comments are unlikely to be published.

Useful LaTeX packages: linguistic examples

This is the conclusion of a short series of entries on LaTeX packages I found useful while preparing the examination copy of my PhD thesis.

Today’s entry is a package for displaying linguistic examples (ie, samples of text which you then want to discuss and analyse).  The LaTeX for Linguists Home Page is a good general resource for linguists and computational linguists using LaTeX. I discuss gb4e here because I had to do some messing around to get it to display example numbers the way I want (and the way my supervisor wanted: he likes in-text references to look like “example (4.1)” rather than “example 4.1″), and to get it to work with cleveref, and no one seems to have written that up to my knowledge.

gb4e

gb4e is a linguistic examples package.

\usepackage{gb4e}

Input looks like:

\begin{exe}
\ex This is an example sentence\label{example}
\ex This is another example sentence.
\end{exe}
This is a cleveref reference to \cref{example}.
This is a normal reference to example (\ref{example}).

You can mark sentences with * and ? and so on:

\begin{exe}
\ex[*] {This is an sentence ungrammatical.}
\ex[?] {This is an questionably grammatical sentence.}
\end{exe}

You can do sub-examples:

\begin{exe}
\ex This is an example.
\ex
\begin{xlist}
\ex This is a sub-example.
\ex This is another sub-example.
\end{xlist}
\end{exe}

A few things to do to make gb4e play really nicely. First, some cleveref config. gb4e doesn’t yet automatically tell cleveref how to refer to examples, so you need to tell it that the term is “example”, and second, if you want braces around the number (“example (1.1)” rather than “example 1.1″ you need to tell it to use brackets:

% tell cleveref to use the word "example" to refer to examples,
% and to put example numbers in brackets
\crefname{xnumi}{example}{examples}
\creflabelformat{xnumi}{(#2#1#3)}
\crefname{xnumii}{example}{examples}
\creflabelformat{xnumii}{(#2#1#3)}
\crefname{xnumiii}{example}{examples}
\creflabelformat{xnumiii}{(#2#1#3)}
\crefname{xnumiv}{example}{examples}
\creflabelformat{xnumiv}{(#2#1#3)}

Also, by default, the gb4e numbering does not reset in chapters. That is, your examples will be numbered (1), (2), (3) etc right through a thesis. You probably want more like (1.1), (1.2), (2.1), (2.2), ie chapter.number. Change to this with the following in your preamble:

% Store the old chapter command so that
% our redefinition can still refer to it
\let\oldchapter\chapter
% Redefine the chapter command so that it resets the
% 'exx' counter that gb4e uses on every new chapter.
\renewcommand{\chapter}{\setcounter{exx}{0}\oldchapter}
% Redefine how example numbers are shown so that they are
% chapter number dot example number
\renewcommand{\thexnumi}{\thechapter.\arabic{xnumi}}
You could also get it to reset in sections by replacing \chapter and \thechapter with \section and \thesection in the above.

Useful LaTeX packages: within document references

This is part of a short series of entries on LaTeX packages I found useful while preparing the examination copy of my PhD thesis.

Today’s entry is packages relevant to preparing within document references. These are both fairly new to me, although not absolutely now.

hyperref

This package turns cross-references and bibliography references into clickable links in your output PDF (at least if you generate it with xelatex or pdflatex), without you having to do anything other than the \ref (or cleveref’s \cref) and \cite and so on commands.

\usepackage{hyperref}

You will probably want to modify its choice of colours to something more subtle:

\usepackage\[citecolor=blue,%
    filecolor=black,%
    linkcolor=blue,%
    % Generates page numbers in your bibliography, ie will
    % list all the pages where you referred to that entry.
    pagebackref=true,%
    colorlinks=true,%
    urlcolor=blue\]{hyperref}

Use black if you want the links the same colour as your text.

One note with hyperref: generally it should be the last package you load. There are occasional exceptions, see Which packages should be loaded after hyperref instead of before?

cleveref

cleveref is a LaTeX package that automatically remembers how you refer to things. So instead of:

see chapter \ref{chapref}

you use the \cref command:

see \cref{chapref}

It handles multiple references nicely too:

see \cref{chapref,anotherchapref}

will generate output along the lines of “see chapters 1 and 2″.

Use

\Cref{refname}

to generate capitalised text, eg “Chapter 1″ rather than “chapter 1″

To use it:

\usepackage{cleveref}

It shortens the word “equation” to “eq.” by default, if you don’t like that, then:

\usepackage[noabbrev]{cleveref}

For some packages that don’t yet tell cleveref how to refer to their counters, you will get output like “see ?? 1″ rather than “see example 1″. You use the \crefname command in the preamble to tell it what word to use for each unknown counter, examples of \crefname will be shown tomorrow for gb4e.
