And if another package with a lot of overlap has unique journals you also need, then you're forced to pay twice for all the titles that appear in both. Try telling faculty that you won't get them access to the journals they need because the publishers are greedy and refuse to allow a la carte leasing. ",

"text": "All empirical fields (although I am in finance): publication bias makes lots of things that are not actually true appear to be statistically significant.\n\nMost empirical papers ultimately rely on a statistical measure for hypothesis testing (like a t-test, F-test, chi-square test, etc.) These statistical tests are generally set up so that if you find a result that supports your hypothesis that there is only a 5% or less chance that you have found this result in error (that is due to random chance.)\n\nThe problem is, you typically cannot get papers publish that find \"no results.\" All academics know that, so they don't even try to publish such papers. So know let's say that 1000 researchers independently decide to test Hypothesis A, which is actually false. 950 of the researchers will get a \"non-result\", and simply stop - they won't try to get it published. 50 researchers will, however, get a false-positive. They *will* submit for publication, and will get published. If everybody knew about the 950 other studies that found nothing, it wouldn't be a big deal since we would figure out the result wasn't really there. But since neither we nor the journals see all those failed tests (because the authors just stop working on them and never write them up for publication), it looks like a new hypothesis has been proven statistically when if fact it's just a bunch of false positives. (this may be what OP was referring too, but it affects all empirical fields, nit just biology.) ",

In the social sciences this is much more difficult because we rely on data observed from real life and you just cannot go get more data. For example, in my field of finance you may want to use stock market data to test a theory. You cannot ask others to replicate the results with different data because there is really only one stock market and you just have to live with the data you get from it.\n\nIn short, it's a very hard problem.",

How it works is, \"I tried one thing, and that didn't work well enough, so I made a bit of a tweak here and there and then it did.\" In those cases, no one wants to publish the failure, because it's going to go into a venue no one reads, and if they do, then they scoop themselves out of the publication that did work. The positive result might have been a Nature paper before, but now it's a minor tweak on earlier already published work, which is going to kill it from the big journals.\n\nI can sympathize with the goal here, and I support mandatory open-access publications for all publicly funded work.

"text": "I know the discussion here is in good spirits, but I can't for the life of me comprehend how anyone could ever come away with such an idea about literary studies. \n\nI mean, it isn't my field (I'm in the History of Art), but humanities scholarship circulates pretty freely between literatures, philosophy, histories, etc. so a lot of reading overlaps. Maybe I just don't get it (this mindset, I mean). It's practically impossible for me to see how people think \"literary studies is just making things up\" or just throwing words around, because (from my perspective) the theoretical work (good theoretical work, obviously) is as rigorous as can be; the archival work is as precise as can be, and just...everything is so logical, so systematic, so incremental. \n\nI mean, read Ricoeur, for example. His work on meaning, metaphor, narrative, hermeneutics...for me he's one of the most systematic and precise thinkers in the history of human thought. There could be countless other examples, but my point is...I just really do not get how it's possible for someone to think \"this is made up, but *that* (perhaps because it contains numbers and graphs?) is not made up.\"\n\nI won't even touch on deconstruction because the lay public pretty much just doesn't get it; they got acquainted with it through highly warped, oversimplified media misrepresentation, so yeah. Deconstruction at its best is perhaps the most powerful critical approach of the 20th century. And really good scholarship (some of Derrida's finer essays, Martin Hagglund's work, etc.) shows that. \n\nI know a lot of this has to do with lay confusion over \"objectivity\" and \"subjectivity\"...differences that draw from a long, confused history involving observation and interpretation, positivism, etc. I know that the 20th-century fascination with empiricism and consequent denigration of literary studies is only a very recent fad. Still, it's incomprehensible to me. It makes me sad, too, because the people who think that way...to imagine how much they are missing out on...wow.",

It's like taking high-school physics and then making claims about what graduate researchers do. It makes me believe the problem is at a more basic level--perhaps something in the way that American schools (or most of them anyway) teach literatures to kids. I mean, of course it'll be pretty formalist at that level because you need to learn the basics of reading and interpreting a text beyond the surface, but if it's giving people such a misguided idea after the fact...maybe something should be fixed there. \n\nYes, you read texts and decipher meaning from them, but no--there is not a \"lot of freedom\" in the \"anything goes\" sense. Meaning doesn't emerge within a vacuum; it emerges from within specific discursive structures. So it's really not the case that you can read this post and interpret it as an allegory on the Middle East crisis--and if you do, there *will* be a specific constellation of discourses that might, plausibly, make such an odd reading sensible.\n\nIt's this crucial condition that seems to get lost when people say you can just read a text and \"make meaning\" from it.

Type inference for ML programs is EXPTIME-complete (and actually printing the inferred type is even worse), but we have still managed to compile large programs without having the sun engulf the planet.\n\nEven fancy, new static analysis techniques tend to collapse when applied to programming languages people actually use. Nobody knows what to do with `eval`, but JavaScript has it whether we like it or not.\n\nSome promote dependent types as the way forward as they allow much more thorough (machine-checked) specification of how some code should behave. However, implementing an underclassman-level data structures homework assignment in this \"correct by construction\" manner is considered a significant research result.\n\nThere's a lot of concern about \"programming in the large,\" but nobody really has the wherewithal to properly study how a range of different language features affect the productivity of professional programmers working on large-scale projects. There have been a fair number of empirical studies, but practical concerns generally limit this to observing students attempting small, artificial tasks. I suspect this is the hardest problem in PL research.\n\nHaskell programs have effects (ok, not that much of a secret, but still something many people are loath to admit).",

It's used for data analysis.\n\nWhen samples are measured for radiocarbon dating using AMS (accelerator mass spectrometry) you directly measure the ratio of C12, C13, & C14. This is different from Libby's way of counting using the beta emissions. Now measuring the carbon ratio is something, but quite literally means nothing without some sort of context (i.e. a standard). This standard will depend on the lab, but the two I'm used to is OX-I and OX-II (oxalic acid, harvest from beet sugar back in the good old days). These standards are used to tune the AMS for a specific sample run and for data analysis. We know the carbon isotopic ratio of OX-I and OX-II...so we normalize \"or fudge\" every data point collected to the ratio of OX-I or -II. \n\nOnce the data analysis is complete, the software spits out a ratio for the sample in question, that ratio is plugged into a equation, background corrected, internal/external error calculated, etc etc.. and out comes a FmC value (fraction modern carbon) and an age (radiocarbon years). This age needs to be calibrated using OxCal to get a calibrated age. \n\nKind of seems...anti-climatic...\n\nedit: Alright...will discourage the use of \"fudging\" the numbers when performing data anaylsis...we *normalize*",

The standard in question here is used by many AMS labs around the world for 14C and has been rigorously tested by intercomparisons. Also, AMS is infinitely more complex than IRMS in that a lot of tweaks can be made in terms of machine tuning and ion source behavior (ion sorcery), therefore, if you didn't normalize the true ratio as you call it would actually just be subject to the conditions of machine during the run.

Only paying for machine time.\n\nIt's also pretty quick work...I can graphitize (well used to...it's been 6 months) 36 samples a day (from 8AM to 5PM). \n\nIt doesn't hurt that home is orange county/San Diego...these sample prep trips are a nice way to go home on the lab's dime. \n\nWell enough about our labs. I notice you're studying geology? What specifically about 129I and 36Cl? Dating some rocks? Like erratics? \n\nI'm personally working on 87Sr/86Sr to determine mega fauna migration during the late Pleistocene.",

Sounds like you get a great deal too. \n\nMy work is a broad look at 129I geochemistry and using it as a tracer/timer in surface water, groundwater, the vadose zone, and a dating tool of groundwater at a proposed deep geologic repository for radioactive waste. We were going to play with 36Cl a bit, but its kind of a hassle. Purdue is the only place to analyze it these days.\n\nYour project sounds pretty cool. You working up in the Yukon/NWT? I have done some work in Beringia and around Dawson. The Yukon paleo survey has soooo many bones just lying around.",

I actually know the guy (Grant Z.) who manages the Yukon Paleo collection. He frequently sends samples down to the Keck...hell he recommended me to my adviser when he got wind I was looking into grad school. I've never seen the collection, but I'll be there getting some caribou mandibles and teeth. \n\nDoes you work bring you to the Yukon? \nYou project sounds neat...a bit over my head, but neat. How is 36Cl a hassle? Hard to isolate? I imagine it get isolated in gaseous form...so a bit...toxic. ",

You should try and stay with Dieter at the hostel across the river, do the sourtoe and definitely check out Diamond Tooth Gertie's casino. \n\nIf you get a chance on your way to Dawson stop in at the collection and have a look around. It's pretty amazing. The archaeological collection is great too. I've met Grant on my way through a few times. It's a small world, particularly amongst people working in the Yukon!\n\nI was working a on a few watersheds throughout the Yukon and up near Fort McPherson for a while looking at geochemical cycling and storage of 129I. We have a few people doing work in Old Crow though as well. \n\nThe reason 36Cl is a hassle is that not many labs can analyze it due the 36S isobar. The sample prep is pretty easy (precipitate as AgCl), but you need a very large AMS with a gas filled magnet to drop the isobaric interference. We are working on doing it with a 3MV, but aren't there yet. Right now only Purdue can run 36Cl easily in North America. ",
