El 19 de enero 2021, el presidente norteamericano, Joe Biden, propuso a la Doctora Rachel Levine como subsecretaria Salud. Es primera persona trans que ocupa un cargo gubernamental federal. La transfobia afloró en Twitter, donde numerosos usuarios se burlaron Levine, atacaron por su aspecto e insistieron era hombre. objetivo este trabajo es entender, cuantitativa y cualitativamente, las repercu...

To challenge the common misconception that there are only four societies in the world that allow polyandry, this paper uses types of polyandry, suggested by Levine and Sangree (1980), to identify polyandrous societies from India, Africa, South America, and North America. Basic issues of these societies are examined within the context of four commonly cited attempts to explain the existence of p...

also help us explore the effects of implementing new traffic rules and control systems without doing potentially hazardous experiments with real traffic. What can physicists contribute to this area of research, which is a traditional area of study in civil engineer-ing? 1,2 You might be surprised to learn that several recent major contributions to traffic science have been made by physicists ap...

(i) why we discount the future, (ii) get weaker with age, and (iii) display risk-aversion 1 I thank Mark Garmaise and David Levine for reading the paper carefully and providing many useful comments. I am grateful to Eduardo Schwartz for help in formulating the problem elegantly in continuous time that allowed me to obtain the main results of the paper analytically. I also thank Michael Brennan,...

We introduce a dynamic model in which the ability of agents to perform certain welfare improving transactions is subject to random and unobservable shocks. We characterize the optimal setup for incentive compatible transactions, the optimal payment system. Implementation involves assigning balances to individual agents and optimally adjusting these balances given the agents’ histories of transa...

What is the role of language in cognition? Do we think with words, or do we use words to communicate made-up decisions? The paper briefly reviews ideas in this area since 1950s. Then we discuss mechanisms of cognition, recent neuroscience experiments, and corresponding mathematical models. These models are interpreted in terms of a biological drive for cognition. Based on the Grossberg-Levine t...
