23 - Asymmetric information: silence, signaling and suffering education
We look at two settings with asymmetric information; one side of a game knows something that the other side does not. We should always interpret attempts to communicate or signal such information taking into account the incentives of the person doing the signaling. In the first setting, information is verifiable. Here, the failure explicitly to reveal information can be informative, and hence verifiable information tends to come out even when you don't want it to. We consider examples of such in
03 - Technology and Invention in Finance
Technology and innovation underlie finance. In order to manage risks successfully, particularly long-term, we must pool large amounts of risk among many, diverse people and overcome barriers such as moral hazard and erroneous framing. Inventions such as insurance contracts and social security, and information technology all the way from such simple things as paper, and the postal service to modern computers have helped to manage risks and to encourage financial systems to address issues pertaini
05 - Inferno IX, X, XI
In this lecture, Professor Mazzotta discusses Inferno 9-11. An impasse at the entrance to the City of Dis marks Virgil’s first failure in his role as guide (Inferno 9). The invocation of Medusa by the harpies that descend while they wait for divine aid elicits Dante’s first address to the reader. The question of literary mediation, posed in the previous lecture in the context of Inferno 5, is explored further, and the distinction Dante draws between the “allegory of poets” and the “

17.57J Soviet Politics and Society, 1917-1991 (MIT)
At its greatest extent the former Soviet Union encompassed a geographical area that covered one-sixth of the Earth's landmass. It spanned 11 time zones and contained over 100 distinct nationalities, 22 of which numbered over one million in population. In the 74 years from the October Revolution in 1917 to the fall of Communism in 1991, the Union of Soviet Socialist Republics, its leaders and its people, had to face a number of difficult challenges: the overthrow of the Tsarist autocracy, the est
17.508 The Rise and Fall of Democracy/ Regime Change (MIT)
Coups, civil wars, revolutions, and peaceful transitions are the "real stuff" of political science. They show us why politics matters, and they highlight the consequences of political choices in times of institutional crisis. This course will help you understand why democracies emerge and why they die, from ancient times to the recent wave of democratization in Southern Europe, Eastern Europe, and the developing world.
Few things are more dramatic than the collapse of a political system, whether
2.737 Mechatronics (MIT)
This course teaches the design of mechatronic systems which integrate mechanical, electrical, and control systems engineering. A computer hard disk drive is an example of a complex mechatronic system discussed in the class. Laboratories form the core of the course. They cover topics such as aliasing, quantization, electronic feedback, power amplifiers, digital logic, encoder interfacing, and motor control. The labs make extensive use of Simulink®, a MATLAB® toolbox which allows
Réduction de la mortalité maternelle - Dakar 2010 : Introduction au colloque. (audio)
Le président de séance rappelle que ce colloque est un moment de réflexion pour confronter les approches et harmoniser le langage. La sexualité humaine est un objet social complexe qui, dans toutes les sociétés du monde, articule le langage, les affects et la physiologie.
La sexualité humaine, à la différence de la sexualité animale, dépasse la fonction de reproduction. Nous sommes des êtres de langage et de société. Le terme même de "reproduction" est trop
21F.704 Spanish IV (MIT)
Spanish IV aims at developing and improving student's oral and written communication through the continued study of the language, literature and culture of Spain, Latin America and Hispanic communities in the United States. It also seeks to improve students' ability to read and appreciate literary and non-literary texts in Spanish, deepening this way students' awareness and understanding of the cultural diversity of the Spanish-speaking world. The course is organized by themes based on contempor
Magnesia-chrome refractory brick
The micrograph shows the detail of the bond system which glues the large grain particles together. In particular, small (5mm) Cr2O3 precipitates are seen in the MgO. Fine particles react to form spinel which directly bond the aggregates conferring high temperature strength.
2.875 Mechanical Assembly and Its Role in Product Development (MIT)
The course presents a systematic approach to design and assembly of mechanical assemblies, which should be of interest to engineering professionals, as well as post-baccalaureate students of mechanical, manufacturing and industrial engineering. It introduces mechanical and economic models of assemblies and assembly automation at two levels. "Assembly in the small" includes basic engineering models of part mating, and an explanation of the Remote Center Compliance. "Assembly in the large" takes a
21F.109 Chinese III (Streamlined) (MIT)
This course is the intermediate level of the streamlined curriculum, which is intended for students who, when they began streamlined I, had some background in the language, whether it be comprehension with limited speaking ability or quite fluent speaking ability. The focus of the course is on standard pronunciation and usage, on reading in both complex and simplified characters, and on writing. It is presupposed that students in Chinese III have already learned the pinyin system of representing

This is the third of the four courses (Chinese I through IV) in MIT's regular (non-streamlined) Chinese curriculum. The four make use of the textbook, Learning Chinese: A Foundation Course in Mandarin (unpublished, but available online), to which are added various supporting materials as needs arise. The foundation level covers core grammar, linguistic culture, basic conversation, the principles of the writing system, and elementary reading. Reading is primarily in the simplified character set t
Caplan on the Myth of the Rational Voter
Bryan Caplan, of George Mason University and blogger at EconLog, talks about his book, The Myth of the Rational Voter: Why Democracies Choose Bad Policies. Caplan argues that democracies work well in giving voters what they want but unfortunately, what voters want isn't particularly wise, especially when it comes to economic policy. He outlines a series of systematic biases we often have on economic topics and explains why we have little or no incentive to improve our understanding of the world
Lipstein on Hospitals
Steven Lipstein, President and CEO of BJC HealthCare--a $3 billion hospital system in St. Louis, Missouri--talks with EconTalk host Russ Roberts about the economics of hospitals. They discuss pricing, the advantages and disadvantages of specialization in modern medical care, and culture and governance of non-profit hospitals vs. for-profit hospitals.

Brady on Health Care Reform, Public Opinion, and Party Politics
David Brady of Stanford University talks with EconTalk host Russ Roberts about American public opinion on changing the health care system. Brady discusses the impact of taxation on public opinion toward health care reform--if the poll includes a measure of the likely increase in taxes necessary to pay for expanding coverage, support for expanding coverage drops dramatically compared to generic polls that ignore costs. He also discusses the role of the party system and partisanship for the health
