Dealing with plagiarism as a teaching assistant

One aspect of starting a PhD program is that I will be responsible for working as a teaching assistant: teaching seminars, grading papers, and so on.

I am worried about the inevitable day when I discover that a student has committed plagiarism and when I am in the position of having to decide what to do about it.

So far, the best plan seems to be to issue a stern warning during my first session with each group of students. It could be something along the lines of:

Do not submit plagiarized work to me.

If you do, you will be reported to the appropriate disciplinary authorities without exception.

You are here to earn meaningful degrees. Plagiarism devalues all of the work you are doing, and I will not tolerate it.

It’s unfair to give some people second chances or the benefit of the doubt while denying it to others. Being consistent seems important, and it also seems plausible that a sufficiently strong warning could prevent the problem from ever coming up in the first place.

Building options and resilience

It seems to me that one fairly central human aspiration is to have a broadening set of options; it’s encouraging to see new options becoming possible, and worrisome to see options that existed before being closed off forever. In addition to satisfying human preferences, broadening options may also serve the purpose of building resilience in the face of massive change. If we don’t know what the future is going to be like, we have all the more reason to avoid committing ourselves to choices that may end up being poorly matched with the circumstances in which we find ourselves.

Previously, I have written about the idea of a steady-state economy. In particular, I stressed the distinction between an economy that is stable in terms of the total biophysical impact of humanity and an economy in which everything stays the same. One critical difference between the ‘constant impact’ and the ‘set in stone’ options is technological development. With a set amount of copper and electricity and silicon we can now make a much better computer than we could ten or twenty years ago. Because we can make better use of resources – as well as avoiding waste, and handling the waste we do produce better – we can still aspire to an improving quality of life, even if we keep the amount of raw material we take from the planet constant and keep the amount of waste we release into the environment constant.

That’s not the only way of keeping our options open, along with those of future generations, but it is a relatively optimistic scenario. I don’t think what matters from a moral perspective is the total number of people on the planet, the size of their homes, or the amount of energy they use. What matters is the richness of their lives. Since the richness of the lives of future generations matters as much as the richness of our lives, we have an obligation to interact with the planet in a way that doesn’t close off too many options for the people who come after us. To me, that implies minimizing serious and irreversible changes in the functioning of the planet system, which in turn requires us to replace the global energy system with a sustainable one, while working to increase the sustainability of other activities. From this perspective, one of the most morally dubious things we can do is continue to invest in a fossil-fuel based economy. Not only will it be increasingly dysfunctional as fossil fuel reserves are exhausted, but our reliance on fossil fuels is the primary cause of climate change.

Life inevitably involves the narrowing as well as the broadening of choices. We can’t hope to keep everything that is possible today possible forever. That being acknowledged, I think a strong case can be made that there is both a practical and moral importance to keeping options open, including across an intergenerational timespan. Similarly, we should pay more attention to irrevocable choices (like “burn all the world’s coal”) than to reversible ones. When it comes to these irreversible choices, we should also be especially on guard for people who simply make the choice that works best for them personally. There is a huge risk of moral corruption wherever the possibility of a big up-front payout with a big long-term cost exists, given that you can take the payout and fob off the cost on others (a favourite strategy of tax-cutting conservatives everywhere). Perhaps adjusting our thinking to pay more attention to keeping options open could be one way of reducing the seriousness of such problems.

The political importance of jobs in the oil sands

Economists sometimes defend inflation by saying that it is a useful means for allowing the real income of some people to fall, without actually reducing the nominal amount. This is connected to human psychology. For some reason, it is more upsetting to have your salary cut by 2% at a time when prices are stable than it is to experience an amount of inflation that generates the same reduction in what you can consume. People like having an income that seems to grow or stay the same, even if it is an illusion, and they hate having an income that seems to shrink.

A related asymmetry arguably exists in terms of entire industries. Once an industry exists, it will fight for survival no matter how irrelevant or damaging it has become. People in the industry will lobby their political representatives for assistance and – especially if the number of people employed is large – they will often succeed.

This is why Canada still has an asbestos industry, even though the material is too dangerous to be used domestically and most people agree that it is unethical to sell abroad.

One reason why I worry about the rapid pace of oilsands expansion is because of the ever-larger constituency of people whose livelihood and financial security now depends on the continued operation of the oil patch. In the future, it may become completely obvious that the oil sands are bad for Canada and bad for the world. Even so, the more people employed by the industry, the harder it will be to wind down. It will also require scrapping more multi-billion-dollar hardware.

Growing the oil sands is politically easy; shrinking them is almost impossible. That’s another argument for slowing the pace of growth. It means there will be less inertia to overcome when we make the transition from digging up ever-more oil to phasing out our fossil fuel industries.

The End of Nature

In The End of Nature, Middlebury College professor and 350.org founder Bill McKibben makes the case that humanity has put an end to nature by altering the climate, and then goes on to consider the implications. McKibben’s book – first published in 1989 – briefly explains why human activities are increasing the quantity of greenhouse gasses in the atmosphere, and why this will produce change on a planetary scale. His tone is mostly one of lamentation. He expresses sadness about that which is already doomed to destruction, before progressing extensively into the question of what can still be saved, and what means might achieve it. Reading The End of Nature in 2012 is dispiriting. It proves how everything important about climate change was well understood decades ago, including why our political and economic systems have done nothing serious to slow it down. Nonetheless, McKibben’s appeal is a poignant and effective one. By putting humanity’s current activities in context, McKibben conveys the reality that what happens to the Earth now will mostly be a matter of human choices, and that the philosophies we adopt in the decades ahead will affect the prospects of all the life forms that depend upon this planet.

The basic idea of the book is that humanity has no so thoroughly altered the planet that nothing can be considered ‘nature’ in the sense of ‘unpopulated wilderness’ anymore. Climate change is the most important and dramatic change humanity has produced, but our chemical signature is also written in the form of novel isotopes from nuclear tests, changes to the ozone layer, and in the legacy of pollution and pesticides. According to McKibben’s definition, nobody my age has ever seen nature – only nature as modified through human industrial activity.

Along with climate change, McKibben devotes a fair bit of space to talking about genetic engineering. He sees it as a possible way of keeping humanity’s billions alive in a world that is increasingly damaged by our choices. But it is also another step away from ‘nature’. He envisions a world of trees and fish and animals modified to tolerate a changed climate, and modified further to better serve human needs. Reading these passages in 2012, it seems like he over-estimated the importance of genetic engineering, or at least under-estimated how long it would take to arrive. For instance, he imagines custom organisms that draw in nutrients through tubes and produce the parts of chickens many humans enjoy eating. Margaret Atwood’s ‘ChickieNobs’ from the dystopian 2003 novel Oryx and Crake are described in basically identical terms in McKibben’s book, but nothing remotely like them seems to exist in the real world. So far, genetic engineering has been more about experimentation than implementation, and nothing too world-changing seems to have arisen from it. Perhaps that perspective reflects ignorance on my part, especially given the evolving character of the global ‘agribusiness’ and biotechnology industries.

Because I borrowed a copy of the book from a library, rather than buying one, I didn’t take the detailed marginal notes that I usually do when reading a book. I did, however, pick out a few passages that I think are especially evocative and worthy of discussion:

On the habits of humanity

“The problem, in other words, is not simple that burning oil releases carbon dioxide, which happens, by virtue of its molecular structure, to trap the sun’s heat. The problem is that nature, the independent force that has surrounded us since our earliest days, cannot coexist with our numbers and our habits. We may well be able to create a world that can support our numbers and our habits, but it will be an artificial world, a space station.

Or, just possibly, we could change our habits.” (p.144 2006 Random House trade paperback edition)

Timing

“I have tried to explain, though, why [dealing with climate change] cannot be put off any longer. We just happen to be living at the moment when the carbon dioxide has increased to an intolerable level. We just happen to be alive at the moment when if nothing is done before we die the world’s tropical rain forests will become a brown girdle around the planet that will last for millennia. It’s simply our poor luck; it might have been nicer to have been born in 1890 and died in 1960, confident that everything was looking up. We just happen to be living in the decade when genetic engineering is acquiring a momentum that will soon be unstoppable. The comforting idea that we could decide to use such technology to, in the words of Lewis Thomas, cure “most of the unsolved diseases on society’s agenda” and then not use it to straighten trees or grow giant trout seems implausible to me: we’re already doing those things.” (p.165)

On caring for future generations

“We flatter ourselves that we think of the future. Politicians are always talking about our children, our grandchildren, and, as individuals, we do think about them, but in the same way we think about ourselves. We lay aside money for them, or land. But we do not really think of grandchildren in general. “Future generations do not vote; they have no political or financial power; they cannot challenge our decisions,” said a perceptive introduction to the United Nations report on Our Common Future. Future generations depend on us, but not vice versa. “We act as we do because we can get away with it.”” (p.170)

Beyond what one person can deal with

“The inertia of affluence, the push of poverty, the soaring population – these and the other reasons listed earlier make me pessimistic about the changes that we will dramatically alter our ways of thinking and living, that we will turn humble in the face of our troubles.

A purely personal effort is, of course, just a gesture – a good gesture, but a gesture. The greenhouse effect is the first environmental problem we can’t escape by moving to the woods. There are no personal solutions. There is no time to just decide we’ll raise enlightened children and they’ll slowly change the world. (When the problem was that someone might drop the Bomb, it perhaps made sense to bear and raise sane, well-adjusted children in the hope that they’d help prevent the Bomb from being dropped. But the problem now is precisely too many children, well adjusted or otherwise.) We have to be the ones to do it, and simply driving less won’t matter, except as a statement, a way to get other people – many other people – to drive less. Most people have to be persuaded, and persuaded quickly, to change.” (p.174)

So McKibben lays out the challenge that has been occupying some of the most capable and driven people in the world for decades (occupying them, but not yet producing even the beginnings of success) and which seems likely to be the defining activity for humanity as a whole for the decades and centuries ahead.

Since 2007, McKibben has been an important organizer of environmental campaigns and the founder of 350.org, an organization that aims to keep the atmospheric concentration of carbon dioxide below 350 parts per million. Beyond that level, the sensitivity of the Earth to greenhouse gasses is such that we would likely see the disappearance of nations like the Maldives along with large parts of nations like Bangladesh and the Netherlands, accompanied by profound changes to physical and biological systems around the world. Keeping the level of greenhouse gas pollution in the atmosphere below 350ppm is incredibly ambitious and far beyond what any large country on the planet is meaningfully aiming for now. If implemented globally, Canada’s policies would probably put us more in the territory of 1000ppm by 2100 – territory that involves changes so profound that they might threaten the future of the human species, as well as the future of countless other less resilient species in the ecosystems of the world.

The End of Nature is a reminder of the scale of the fight we have on our hands, as well as of the stakes involved. If we are to have any chance of succeeding, we must be committed, passionate, strategic, self-sacrificing and willing to do what has never been done before.

Trying the same thing and expecting a different result

I’m sure everyone has heard this quote and its variations: “The definition of insanity is doing the same thing and expecting a different result”.

While it may have a kind of folksy charm, I think the position being argued here is plainly false. While there will never be a simple an unambiguous definition for a concept as subjective as ‘insanity’, I think the definition above can be effectively refuted.

First, we need to be careful about what we mean by ‘the same thing’. A man trying to open a pickle jar is likely to do ‘the same thing’ several times – trying to twist off the lid in what he believes to be the right direction. Frequently, the repeated application of effort will do the job. It can be argued that this doesn’t contradict the original claim. ‘Twisting the lid of a pickle jar that I have already twisted five times’ is not ‘the same thing’ as ‘twisting the lid of a pickle jar that I have already twisted four times’. Fair enough, but this interpretation supports the view that repeating the same behaviour can be an intelligent and successful strategy, rather than the mark of mental imbalance.

Second, there is a reasonably admirable practicality involved when a person tries something several times and notes whether the result changes. I might try throwing five darts at a dart board and get a different result with each one. Less trivially, I might apply to ten graduate schools and get a range of answers. In these circumstances, my expectations are more complex than ‘same result’ or ‘different result’. I may well get into nuanced claims like: “I thought it was pretty likely I would hit the dart board, but I had no idea where” or “I am likely to get into some schools, but probably not all of the most prestigious ones’.

The world often involves complicated interactions between phenomena that incorportate chaotic elements. In a world like that, trying the same thing over and over can be an essential way of sorting out what the governing dynamics of a relationship really are. The fact that trial and observation are at the heart of the scientific method are probably why this flippant witticism annoys me so much.

As is often the case, XKCD has already made this point in a more effective and eloquent way than I can.

Gambling with high stakes

As with other high-risk activities, I think gambling on climate change is irresponsible and reckless, even if the people making that bet turn out to be right.

If a person runs across a minefield in order to experience the thrill of danger, few people are likely to congratulate them for their bold choice in the face of uncertainty. Even if you get away with it, it is foolish to run careless risks, especially when the consequences of getting it wrong are severe. This is why Russian Roulette is commonly regarded as an absurdly irresponsible pastime.

Say there is some powerful negative feedback that climate scientists haven’t yet identified. And say it manages to reduce the severity of climate change substantially. Imagine it is 2100 and we are looking back at 2012. I think the people considering the problem from that vantage would be quite willing to recognize how scary climate change looked in 2012. I also think they would be willing to chastise us for our inactivity on the problem, even in a scenario where it worked out that our most extreme fears for what climate change might mean weren’t recognized. Rather than being concerned about climate change ‘alarmists’ who called for action, I suspect impartial citizens in 2100 would be critical of the people who wanted us to plow heedlessly on with fossil fuel development, despite the serious outstanding questions on what effect that would have on the future of human civilization.

From any rational perspective, it makes sense for the world as a whole to take serious action to reduce the seriousness of climate change and the probability of extremely bad outcomes. The problem is that this course of action is not in the short-term interests of many individuals, including powerful people whose wealth and influence is rooted in the status quo.

The real question, when it comes to climate change, is how to make individuals, companies, and countries behave more like they would if they were taking the rights and welfare of everybody seriously. Something like the Categorical Imperative (or even the Harm Principle) provides the moral backing for this view. The question is how to discourage selfish and destructive behaviour while encouraging the cooperation and sacrifice that are required to protect the planet and discharge our duties with respect to future generations.

Secrets

You would think that people would be excessively defensive when it comes to their most personal secrets and – while that is often the case – there are also a surprising number of occasions in which people seem eager to share them with relative strangers.

Telling a secret is cathartic, and I suspect that explains a good part of this strange eagerness to disclose. If there is something that you feel you need to keep private, it must be connected with some topic of anxiety for you. Whenever you are reminded of the secret you are keeping, you are reminded of the anxiety or shame or doubt that is the motivation for the secrecy. Telling a secret is thus a form of psychological unburdoning. This may explain why psychiatrists have such a lucrative trade, or why websites like PostSecret do not lack for material.

While sharing a secret can certainly provide a strange combination of thrill and relief, it doesn’t follow that this unburdoning is a good idea. You may feel an early sense of trust and connection with a person, but that doesn’t mean they won’t eventually use your secret in a way that harms of embarrasses you, whether by accident or by design.

The balance, then, is between trust and caution in a world that will not always treat you kindly.

Excluding traffic noise

My latest effort to avoid the constant sound of traffic and streetcar noise in my bedroom consists of wearing DeWalt DPG62-C ‘Interceptor’ Protective Safety Earmuffs over top of foam earplugs.

The earmuffs are rated for 29 decibels of sound reduction, while the earplugs are supposedly good for 32. The sound reduction doesn’t seem to be equal across the range of frequencies I can hear. Birdsong comes right through strangely unaffected, and the rumble of heavy trucks and SUVs remains perceptible, along with the clang and whoosh of streetcars. Together, the two forms of hearing protection do pretty effectively exclude traffic noise, at least when I have my window closed. Whether the whole setup will remain in place overnight is another question.

Wearing the combination is actually a bit disconcerting. There is a constant hiss in my ears, which I think is a combination of the hiss you get from hearing damage with the quiet flow of blood through my ears themselves. If I walk on pavement, each step produces a loud pounding noise. Even walking softly on a wooden floor in socks, I can hear my joints complain slightly when I put my weight on them. For some reason, wearing all this ear protection also makes me more aware of my body, from the mild ever-present pain in my left shoulder to the bodily exhaustion that characterizes the end of another frustrating and largely fruitless day.

We will see whether this combination of tools helps square the circle of a person who is always intensely irritated by traffic noise living in a thin-windowed second-floor apartment overlooking one of Toronto’s busier urban streets.

Forms of address

One of the trickier aspects of corresponding with lots of relative strangers is never knowing quite what to call people.

This is all in relation to written communication. In one-on-one speech, I go out of my way not to call people anything at all.

Academic titles

To start with, there is the eternal question of how to refer to an academic who you don’t know. They probably have a title, which might be ‘Associate Professor’ or ‘Assistant Professor’ or just ‘Professor’. Do you call everyone ‘Professor X’? Or do you use the title on their website? What about people who are excessively quick to call themselves ‘professor’? I have seen it on the business card of a doctoral student.

My solution – call everybody with a doctorate ‘Dr. X’. It doesn’t matter if they just got their doctorate yesterday or whether they have won an armload of Nobel Prizes. ‘Dr. X’ is a perfectly polite form of address between strangers.

Exception: close friends and fellow former students. You may have worked half a decade to get that post-nominal P.H.D., but if we were in first year together I reserve the right to call you by your first name indefinitely.

Other titles

I basically ignore them. ‘Reverend X’ and ‘Lieutenant X’ and ‘Engineer X‘ and ‘Mayor X’ and ‘Prime Minister X’ are all liable to be referred to simply as “Mr. / Ms. X”.

Women

It’s a bit embarrassing that there even has to be a space for this, but such are the sexual double standards of our society. There is nothing as neutral as ‘Mr. Smith’ that you can call a woman. Every option carries a political message. Using ‘Miss Smith’ or ‘Mrs. Smith’ means buying into the somewhat absurd notion that a woman’s whole identity changes when she gets married (and when a man’s does not). I use ‘Ms. X’ anytime I can’t call someone ‘Dr. X’. That goes for any stranger, usually until they specifically tell me to call them something else.

Someone who you know nothing about

Say you discover that www.websitename.com has been horribly defaced. You want to contact ‘webmaster@websitename.com’ but you don’t know any part of their name, or whether they are male or female.

In this circumstance, I usually go with ‘Good [time of the day]’ if I am being less formal and ‘Sir or Madam’ if I am being more formal.

Referring to me

I am perfectly happy to have everybody call me ‘Milan’.

Whenever I see a letter for ‘Milan Ilnyckyj, BA’ I know it is UBC writing to ask for alumni donations.

Lark sleep monitor

For the past couple of months, I have been using a Lark sleep monitor. It’s an accelerometer that you wear on your wrist at night that interfaces with your iPhone. It both works as an alarm clock and as a measuring device that provides data on the length and quality of your sleep. You set when you want to wake up and it wakes you at that time with nearly silent vibration (and a backup sound alarm from the phone).

The device has a few obvious uses. If two people sleep in the same bed but normally wake at different times, the Lark would allow one to more easily wake on time without waking the other. The Lark also lets you collect statistics about yourself, and evaluate how well you sleep in different environments and conditions.

For instance, I slept for an average of 8:41 per night when on vacation at my aunt and uncle’s very quiet house in Bennington, Vermont (with one early morning on December 25th). That compares with an overall average sleep time of 7:45 over the past couple of months.

So far, I have collected data for 86 days. More accurately, I have data for 81 of those days and null values for the five days when I wasn’t able to use the Lark – for instance, because I was taking an overnight Greyhound.

My recent sleep stats

This table shows some simple summary statistics:

Mean Median Standard deviation
Time asleep 7:45 7:56 2:00
Sleep quality 8.5 8.7 0.84
Fell asleep in 0:37 0:30 0:34
Woke up (# of times) 18.9 18 6.39

 

In blue, this time series shows time spent asleep. In pink, it shows how much time was spent falling asleep:

This is a histogram of time spent asleep:

And this shows the frequency of the different qualitative sleep ratings assigned by the Lark software:

The Lark software informs me that the amount of time it takes me to fall asleep “needs work”, as does the number of times I wake per night. My overall length of sleep and sleep quality it deems “OK”.

The biggest thing that jumps out at me from my own data is the sawtooth pattern of sleep. I tend to alternate between a night with relatively little sleep (about six hours) and a night with relatively much (about nine hours). Given that I usually need to wake up at 6:30am or 6:45am, these correspond to nights when I go to sleep around midnight and others where I collapse around 9:00pm or 10:00pm.

Remember, the Lark distinguishes between time spent falling asleep (the period before the first time of prolonged stillness detected by the Lark) and time spent actually asleep. A night recorded as eight hours of sleep is therefore a night with eight hours of stillness comparable to that of sleep, rather than a night when you spend eight hours in bed. Being able to distinguish those two things may be the most valuable thing about the Lark.

Evaluation of the Lark

Overall, I think the Lark works very well. It has never failed to wake me up, and the iPhone software works well.

One suggestion to all iPhone owners is to put your phone in ‘Airplane mode’ at night. That way, it doesn’t beep or buzz when you get late-night texts and emails. You can still use the Lark in this mode, but you do need to follow a simple procedure:

  1. Set the iPhone to ‘Airplane mode’
  2. Manually turn Bluetooth back on
  3. Connect to the Lark
  4. Set your alarm time in the Lark software
  5. Sleep, and be woken

One useful feature the makers of the Lark could add would be the ability to set pre-programmed alarms for different days of the week. For example, you might set your default Monday-Friday alarm for 6:30am or 7:00am, but your weekend alarm for a more reasonable 9:00am or 10:00am.

One side note: it is easy to transfer the basic sleep data from the Lark into your preferred statistical analysis software. For people who don’t want to do that, the company sells an absurdly overpriced (US$$159!) subscription service that keeps track of your data for you online and provides ‘coaching’.
