Dust to dust

Back on the 6th of February, I first noted the presence of some kind of opaque foreign matter on the sensor of my Canon Powershot A510 digital camera. Today, I examined what has taken place since.

The state of the sensor:

Note: the colour cast on the original is just because I shot it using auto white balance and tungsten illumination. The second was taken using sunlight. The general speckle pattern all over it is from the wall, not the sensor.

Both shots were taken at the smallest aperture allowed by the A510 at the shortest focal length (f/8). To me, the comparison indicates a worsening situation. There has been speculation that the foreign substance is not dust, but mold. That would be consistent with the fact that it seems to be worsening, as well as to how the problem first emerged after a period of particularly dismal and rainy weather.

Why it matters, and what to do

Shots that involve areas of solid colour as well as small apertures frequently require touching up in Photoshop to remove the blotches. Sometimes, that isn’t even possible for me. (Look near the ground, to the left of the chapel.) Cleaning the sensor would require paying a technician rather more than the value of the camera. I bought it in North Vancouver for C$273.55 (£132), which included a 512 meg SD card that can be used with a new camera. Replacing it with a comparable camera would cost less (because this model has been replaced by newer ones) and more (because everything costs more in England). The big choice is whether to replace the thing, or start putting money into a digital SLR fund.

Having a camera small enough that I literally carry it everywhere has quite a bit of value to it. Having a DSLR would probably improve the quality of photos that I put on here, but it would definitely be more of a conspicuous item to carry and use. It would also further stress iPhoto, with larger image files…

…wanders back to his reading, pondering…

First UK scholarship

This morning, I learned that I won Wadham College’s Senior Scholarship: “awarded on the basis of academic merit and postgraduate potential.” The award is £500, as well as including one meal a week at high table. It will make a good contribution towards my college and university fees for the coming year.

Having not eaten in hall since the first couple of weeks of this year, it will be good to do so once a week next year. It will certainly increase the degree to which I know the faculty here.

It’s a man’s life… in the British Dental Association

Nervous as I (very seriously) am about seeing a British dentist, going a year or more without a professional cleaning and examination is just not a good idea. Can anyone who is a long-term resident of Oxford point me towards a dentist that is:

  1. Capable
  2. Covered by the NHS (which covers students staying over a year)
  3. Taking patients

If it’s impossible to get all three, condition two may have to go. Most of my teeth have had some kind of cavity preventing coating applied to them. It comes in a little syringe, looks blue, and tastes very sour. They use what seems to be a powerful ultraviolet light to harden it. A dentist that can check on the status of those coatings and replace ones that fail (which seems to happen on a tooth or two a year) would be ideal.

[Update: 21 July 2006] It seems my Canadian dental insurance carries over to the UK. Consider criterion two stricken.

Ten years of Daily Shows

American Institute Library

Yesterday was a notable birthday, today is too: the tenth anniversary of The Daily Show. I maintain that The Daily Show is the only televised news that is really worth watching. Indeed, it is the only kind I have felt the slightest impulse towards watching regularly. Whereas television news is usually a repetitive and less detailed summary of printed news, The Daily Show says something new.

Given how absurd American politics and world current events can be, it seems strangely appropriate to have it presented in a comedic form. A certain night in November 2004 might have been even more psychologically damaging, but for their special coverage. In any case, I salute Jon Stewart and I wish I had one of these shirts.

On walking into lamp posts

In one of their less well considered comments, The Economist said the following this week, when discussing the upcoming European Galileo Positioning System, which is to exist in parallel to America’s Global Positioning System (GPS):

GPS is accurate to within about 15 feet (5m); fine for navigating a car but too imprecise for pedestrians.

Thankfully, at least some pedestrians seem to have natural navigation systems that operate at such ranges with no satellite data whatsoever. It’s a trick even children seem capable of pulling off.

PS. Incidentally, the Galileo Positioning System seems like a pretty easy thing to implement:

Time – Galileo’s position

01:00:00 – Under the Church of Santo Croce, Florence (dead)
01:00:01 – Under the Church of Santo Croce, Florence (dead)

Environment and representation

Revising the fish paper, and reading Bromley and Paavola on environmental economics, the question of the nature of ethical resource relations between the rich and poor world keeps arising. In particular, the issue of paternalism is persistent. The question must be asked of whether there are individuals or groups who ‘know better’ when it comes to environmental choices and, if so, how the superiority of their understanding can be verified and legitimated.

Whether it is Angolan diamonds or West African fish, there is often a case to be made that rich world access to commodities in the poor world has harmful effects. It may fuel conflicts (as with diamonds), it may reduce the future possibilities for resource use within the poor countries (as with fish), and it may enrich corrupt or non-representative elites while not benefitting the population at large. People have generally been critical of the Chinese government for striking resource deals with states that the west shuns because of their poor human rights records and lack of democratic credentials.

The big question, it seems, is how to treat the interests of people in non-representative political systems. Do people in democratic systems (or rich countries) have an obligation to effectively act as their agents, anticipate their preferences, and try to guide outcomes towards satisfying them?

Much recent policy seeks to do exactly this. When China decides that the electricity and prestige generated by the Three Gorges Dam is worth more than the flooded territory and other costs of construction, on what basis can or should we say that they are wrong? We can accuse them of short-term thinking (though our right to do so in anything beyond an advisory manner is dubious) or of violating the rights of individuals (which almost always happens when people are forced to do things in systems that lack political and legal accountability). All that said, the idea that rich states or international organizations can take up the cause of representing the general population of China strikes me as a problematic one.

Naturally, there are also accusations of hypocrisy. How many environmental choices within the rich world have been made on the basis of short-term thinking? How many have harmed a great many individuals for dubious value? Do not the states which are undergoing the process of development today have the right to make the same mistakes as states that have already developed did in the past? To the last of those, it can be responded that our level of understanding about the world has improved substantially since the industrial revolution. When developed states first used DDT, they were not aware of important consequences the introduction of that chemical into the environment would have. Arguably, the same can be said of all the coal that was burned to generate steam power and electricity. The trickier question is whether improved knowledge creates an obligation on the part of developing states to make choices that avoid incurring the kind of harms already suffered in the developed world.

There are also international efforts to encourage better environmental policy that might reasonably be seen as empowering, rather than paternalistic. The Publish What You Pay Initiative and Extractive Industries Transparency Initiative are trying to encourage (or require) resource extracting firms to publish the details of their contracts with governments. This allows scrutiny by the domestic regulators of the firms, by different branches of the governments involved in the contracts, by people living under the authority of those governments, and by international bodies. Presumably, having access to such information could allow for the mobilization of political energy, on the part of any or all of those organizations. At first glance, this model is more appealing than the paternalistic one.

In the end, this is reflective of a larger overall tension within environmental debates. There are certain groups that are often willing to promote optimum outcomes (scientists and economists in particular) that are based on analyses that are rigorous according to standards established within their own disciplines. Then, there is a political process that arrives at decisions on the basis of ongoing political realities – many of which have nothing to do directly with the nature and importance of the environmental issues in question. Finally, there are those who assert the fundamental rightness of views or policies on the basis of some combination of these considerations and others. Such a view suggests that there is an ideal policy (or at least a better policy) out there, but that its nature is not fully captured in technocratic assessment and does not arise spontaneously from the political process. I believe this intuitively, but have a great deal of trouble sketching out the details.

On what basis, however, can the desirability of this kind of policy be asserted? One mechanism is democratic endorsement. Many theorists assert the value of open discussion as a mechanism through which policy might be chosen. Of course, translating discussion into action brings it up against all the barriers produced by existing distributions of power. Likewise, people are not equally capable of engaging in discussion – especially when expert knowledge is a required currency in order for arguments to be taken seriously.

These are not questions to which I see straightforward answers. There is no group that can be trusted to evaluate the situation from a neutral perspective. There is likewise no solid way to assert which values are important, and how important each is with respect to others. The easiest solution, from the perspective of those trying to act in the world, is to identify those areas where present practice deviates most substantially from ideal practice as best understood, and where the gap between the two can be closed or reduced through available and acceptable means. I call this the strategy of picking low-hanging fruit. Of course, the assumption behind this strategy is that the big questions above will eventually be resolved to the satisfaction of most, allowing for further progress. There is plenty of reason to be skeptical about that.

Happy Birthday Mica

Today is my brother Mica’s birthday. That cannot but re-enforce the fact that I have seen neither he, Sasha, nor my father since September 22nd, 2005. In five days’ time, it will have been ten consecutive months.

As I’ve said before, I am not too concerned about spending such a long time away from most of my closest friends. I know they will be more or less the same people when I get back as they were when I left, though perhaps with a few extra letters after their names. Even with the ones with whom I almost never speak – such as Alison and Astrid – I have a good level of confidence that I will be able to relate to them in a comparable way, once I return to Vancouver (however briefly it might be for). It seems different with my brothers, however. While most of us are now stabilizing as people, they still seem to be at the stage when things are taking their direction. Great as the opportunity to be at Oxford is, it’s a saddening thing to be missing.

That said, I am sure they are finding lots of good ways to spend their time. Mica, as I understand it, if off at a wedding somewhere on Vancouver Island. Hopefully, I will be able to reach him over the phone later tonight. In any case, my best wishes go out to him for the year ahead.

Nomenclature

Whoever names Israeli operations in Lebanon must have a real sense of irony:

Operation Peace for Galilee: Israeli invasion of Lebanon in 1982, in support of Maronite Christian militias. Initially presented by Ariel Sharon as a plan to advance 40km into Lebanon, it was apparently always meant to go as far as Beirut.

Operation Accountability: A week-long invasion of southern Lebanon in 1993.

Operation Grapes of Wrath: A series of air and artillery strikes in 1996, designed as an assault against Hezbollah. Admist the 20,000 shells fired into Lebanon was one that killed 118 Lebanese civilians who were sheltering in a UN base.

Regardless of the validity of Israeli arguments about a strong retaliatory response being the only way to prevent future kidnappings and attacks, ongoing Israeli actions appear increasingly out of proportion to their ostensible provocations. Hopefully, some means will be found soon to rein in the situation.

Best laid plans

Grafitti near the Oxford Canal

Between tomorrow and Friday, I have resolved to achieve a burst of productivity. That means being up and doing something worthwhile by 9:00am each day. It also means finishing the following bits of reading:

  1. Lomborg’s The Skeptical Environmentalist (re-reading)
  2. Lindsay Johnson’s MA thesis
  3. Bromley and Paavola’s Economics, Ethics, and Environmental Policy
  4. Faulkner’s “Barn Burning”
  5. Mukund Rajan’s M.Phil thesis
  6. Bernstein’s The Compromise of Liberal Environmentalism
  7. Karen Litfin’s Ozone Discourses

In addition to that, I am going to put a good deal of thought into the direction in which to take the thesis. Hopefully, the editor from the MIT International Review will get back to me with information on what editing is needed, precisely, and I can get started on that as well. I will also finish looking up the missing bits in the bibliography of Dr. Hurrell’s that I am editing.

One last element that I will add to the plan, for the moment, is to sort out when exactly I will be going to Dublin/Prague and buy my tickets. I am thinking that I will do so sometime after August 16th, because I will have another trio of tutorial days ending that Tuesday.

I will post updates as the plan progresses. If I finish all of this early, more elements will be added.

[Update: Tuesday 1pm] The chapter 12 research assistance work for Dr. Hurrell is done. Item four is read.

[Update: Wednesday 9pm] The Johnson thesis is finished. I have also gone through the fish paper and identified some places where the sources need shoring up, as well as other general editing issues. A few more chapters of Bromley and Paavola’s book are done. Some necessary Scotland-prep was completed, as well as paperwork for the RA job.

Movie physics

Apparently, the physics in The Da Vinci Code are no better than the history or theology. (Though this review is more about general plausibility than physics, per se.) Let it be known that Insultingly Stupid Movie Physics is among the greatest of all websites.

The review of The Core is funny enough to be worth reading, even if you haven’t seen that awful, awful film. People making films should probably take a careful look through their generic list of bad physics. Of course, scientific accuracy may not be terribly likely to put people in cinema seats, or sell DVDs.
