Professor of Public Policy at the NYU Marron Institute for Urban Management and editor of the Journal of Drug Policy Analysis. Teaches about the methods of policy analysis about drug abuse control and crime control policy, working out the implications of two principles: that swift and certain sanctions don't have to be severe to be effective, and that well-designed threats usually don't have to be carried out.

I'd be a nice turn if political reporters routinely exercised half as much critical judgment as this sports reporter does here. (And then there's Fred Hiatt.)
But Mark, you're neither a scientist nor a physician, so according to to Dr. Casson, we shouldn't listen to you.
Here's a link to a relevant Malcolm Gladwell story that discusses this issue and more specifically, the study that is being run at UNC.
Casson's position is remarkable. How much of a scientist do you need to be to figure out that:
1. Getting participants by sending out letters to last known addresses is a terrible way to get participants. You're automatically biasing the sample.
2. That comparing NFL players to college players rather than the population at large is a terrible way to judge the effect. It's like determining if NBA players are tall by comparing them to college basketball players. Notice too that the college players will have played through college and in some cases, a year in the NFL. So, in my NBA analogy, you're picking out relatively tall college players for the control group.
Also, I have a question about the approval by the Wayne State review board. My impression is that review boards do not judge the validity of a proposed design. They only concern themselves with the ethical aspects of the study – will it harm the participants, is there suitable informed consent, absence of coercion, etc. Is that correct?
Bernard,
It depends on the IRB and the membership. If there is a statistician on the IRB, it's very likely that power issues will come up in the review. Designs that are biased against finding an effect are unethical generally. They are especially unethical when it is in the sponsor's interests not to find an effect.
Will it come up in the IRB at Wayne State? That's tough to say, without knowing the charge to the IRB (it varies some from institution to institution) and the makeup of the IRB.
Dennis,
Thank you.
Well, the NYT, New Yorker and Newsweek (and no doubt other MSM types) seem to have been put on alert. So parents, wives and perhaps even "jocks" will think twice… as long as they are able to do so.
Asal mula web Judi Poker Online Mengelokkan dipercaya di Dunia.
Dari segi buku Foster’ s Complete Hoyle, RF Foster menyelipkan “ Permainan situs pokerqq paling dipercaya dimainkan mula-mula di Amerika Serikat, lima kartu bikin masing masing pemain dari satu antaran kartu berisi 20 kartu”. Tetapi ada banyaknya ahli tarikh yg tidak setuju diantaranya David Parlett yg menguatkan jika permainan situs judi poker online paling dipercaya ini mirip seperti permainan kartu dari Persia yang dibawa oleh As-Nas. Kurang lebih sejahrawan menjelaskan nama produk ini diambil dari Poca Irlandi adalah Pron Pokah atau Pocket, tetapi masih menjadi abu-abu karena tidak dijumpai dengan pasti sapa yg menjelaskan permainan itu menjadi permainan poker.
Walau ada sisi per judian dalam semua tipe permainan ini, banyak pakar menjelaskan lebih jelas berkaitan gimana situs judi poker mampu menjadi game taruhan yang disenangi beberapa orang dalam Amerika Serikat. Itu berjalan bertepatan dengan munculnya betting di daerah sungai Mississippi dan daerah sekelilingnya pada tahun 1700 an serta 1800 an. Pada saat itu mungkin serius tampil terdapatnya keserupaan antara poker masa lalu dengan modern poker online tidak hanya pada trick berspekulasi tetapi sampai ke pikiran di tempat. Mungkin ini lah cikal akan munculnya permainan poker modern yg kalian ketahui sampai saat tersebut.
Riwayat awal timbulnya situs judi poker paling dipercaya Di dalam graha judi, salon sampai kapal-kapal yg siapkan arena betting yg ada didaerah setengah Mississippi, mereka terkadang bermain cukup hanya manfaatkan 1 dek yg beberapa 20 kartu (seperti permainan as-nas). Game itu terkadang dimainkan langsung tidak dengan diundi, langsung menang, punya putaran taruhan, dapat meningkatkan perhitungan taruhan seperi game as-nas.
Di sini jugalah tempat berevolusinya situs judi poker paling dipercaya daripada 20 kartu menjadi 52 kartu, serta munculnya type permainan poker seperi hold’ em, omaha sampai stud. Herannya orang melihat bila poker stud jadi poker pertama dan classic yang telah dimainkan lebih daripada 200 tahun.
Diakhir tahun 1800 an sajian Poker Online mulai disematkan lagi ketentuan baru diantaranya straight dan flush serta beberapa type tipe yang lain lain seperti tipe poker low ball, wild cards, community cards of one mode dan lainnya.
