I revisit the question of whether entrepreneurs face liquidity constraints in business formation. The principle challenge is that wealth is correlated with unobserved ability, and adequate instruments are often difficult to identify. This paper uses the son’s birth order as an instrument for household wealth. The instrument would likely not be useful in Western data, but it is in many non-Weste...

Knowledge is limited on mortality of grand multiparous women ( 5 deliveries), whose hormonal, metabolic, and social conditions differ from the average. The authors studied overall and cause-specific mortality in 1974–2001 among 87,922 grand multiparous women including 3,678 grand grand multiparous women ( 10 deliveries) in Finland. Standardized mortality ratios were defined as ratios of observe...

Repeated deliveries might disturb the levator function and increase defecation disorders. In this prospective study, we determined the electric activity of the levator ani muscle (LAM) in nullipara, multipara, grand multipara, and great grand multipara (20 subjects for each group). Multiparity, grand multiparity, and great grand multiparity were defined as women having 2 - 5, 6 - 9, and 10 and ...

This paper presents the Golem Group/University of California at Los Angeles entry to the 2005 DARPA Grand Challenge competition. We describe the main design principles behind the development of Golem 2, the race vehicle. The subsystems devoted to obstacle detection, avoidance, and state estimation are discussed in more detail. An overview of vehicle performance in the field is provided, includi...

Stanford on Stanley, the winning robot in the DARPA Grand Challenge. Between July 2004 and October 2005, my then-postdoc Michael Montemerlo and I led a team of students, engineers, and professionals with the single vision of claiming one of the most prestigious trophies in the field of robotics: the DARPA Grand Challenge (DARPA 2004).1 The Grand Challenge, organized by the U.S. government, was ...

The function and eventual fate of immune cells is largely determined by factors controlling their movement through distinct parts of our body. And the molecular basis for this control is provided for by chemoattractants and cell adhesion molecules. This importance of immune cell traffic in immunity has not always been fully appreciated. In fact, cellular immunology has traditionally concentrate...
