We introduce a model of network formation whose primitives consist of a feasible set of networks, player preferences, rules of network formation, and a dominance relation on feasible networks. Rules may range from noncooperative, where players may only act unilaterally, to cooperative, where coalitions of players may act in concert. The dominance relation over feasible networks incorporates pla...

CommunIcations to the Editor genesis ofthe pulmonary edema in this patient. Indeed, endorphins are released in stress situations and they can adversely affect physiologic systems, such as respiration and circulation.’ In the human fetus at term, plasma levels of beta-endorphins and betaLPH are inversely correlated with arterial pH and Po5 suggesting that hypoxia and secondary acidosis may be im...

Puberty is defined as the awakening of the hypothalamic-pituitary gonadal axis. Sheep are seasonal breeders, experiencing an annual period of reproductive quiescence and renaissance that can be utilized as a model for the onset of puberty. Kisspeptin and gonadotropin-inhibitory hormone appear to be important for the seasonal shift in reproductive activity and the former is mandatory for puberty...

Jt is now well established that myocardial dysfunction, once thought to be indicative of irreversible tissue damage, is in many cases reversible. This has led to the concepts of myocardial "stunning"1'2 and "hibernation."3 In both of these conditions, myocardial function is reversibly compromised; in stunning, myocardial function is decreased in response to a previous ischemic insult, and blood...

The chemokine receptor CCR7 plays a crucial role in the homing of central memory and naive T cells to peripheral lymphoid organs. Here, we show that the HIV-1 accessory protein Vpu downregulates CCR7 on the surface of CD4(+) T cells. Vpu and CCR7 were found to specifically interact and colocalize within the trans-Golgi network, where CCR7 is retained. Downmodulation of CCR7 did not involve degr...

This paper studies whether conformism behavior affects individual outcomes in crime. We present a social network model of peer effects with ex-ante heterogeneous agents and show how conformism and deterrence affect criminal activities. We then bring the model to the data by using a very detailed dataset of adolescent friendship networks. A novel social network-based empirical strategy allows us...

The coexistence of a predominantly poor opinion of free markets and lack of education in economics are two documented features of France. In this paper, we use data collected through an Internet-based survey conducted in December 2009 in order to test whether this situation is more than a mere coincidence. A first regression model allows us to study how personal characteristics, general and eco...

We propose a model on strategic formation of communication networks with (i) link specificity: the more direct links somebody maintains, the less she can specify her attention per link, the lower her links’ value, while this negative externality was previously ignored in the communication context, and (ii) value transferability via indirect links for informational but not for social value from ...
