Goldberg, Robert A. | Denver: Queen City of the Colorado realm | In the spring of 1921, William Joseph Simmons stepped from a train at Denver's Union Station. Dressed in a well-fitted suit emblazoned with lodge buttons, this tall, heavy-set man attracted little notice from the crowd. Few Denverites realized that on the train platform stood the self-proclaimed Imp... | 1991 | |

Shirley, Peter S. | Natural image statistics for computer graphics | The class of all natural images is an infinitely small fraction of all possible images. The structure of natural images can be statistically modeled, revealing striking regularities. The human visual system appears to be optimized to view natural images, as opposed to any possible image, and therefo... | Natural image | 2001 |

Stevens, Kenneth | Relative timing | Relative Timing is introduced as an informal method for aggressive asynchronous design. It is demonstrated on three example circuits (C-Element, FIFO, and RAPPID Tag Unit), facilitating transformations from speed-independent circuits to burst-mode, relative timed, and pulse-mode circuits. Relative ... | 1999 | |

Qin, Xianhong; Wei, Dennis Yehua; Yu, Zhou; Xiong, Ning | Urbanization, Suburbanization, and Population Redistribution in Urban China: A Case Study of Nanjing | This paper analyzes the urbanization and suburbanization of Nanjing, an ancient capital and a new Tier-1 city in China, from 1990 to 2015. We use on China's census and survey microdata and the shift-share methods to examine population redistribution and spatial expansion in the city. The results sh... | Urbanization; Suburbanization; Migration; Population Redistribution; Nanjing, China | |

Smith, Ken R. | Biased estimation in policy research: an illustrative example of ridge regression in a health system model | The paper develops an argument for the necessity of examining individual coefficients in policy models. As a result of this need, it is posited that something other than OLS estimators should be used since they are inflated and have extremely large variances when multicollinearity is present. Furthe... | Policy models; Health systems; Ridge regression | 1980 |

Gerig, Guido | Twin-singleton differences in neonatal brain structure | Twin studies suggest that global and regional brain volumes are highly heritable. However, estimates of heritability vary across development. Given that all twin studies are open to the potential criticism of non-generalizability due to differences in intrauterine environment between twins and singl... | 2011-01-01 | |

Hawkes, Kristen | Life history theory and human evolution : a chronicle of ideas and findings | Fertility ends at similar ages in women and female chimpanzees, but humans usually live longer and mature later. We also differ from our closest living relatives in weaning infants before they can feed themselves. The comparisons pose questions about when and why the distinctively human life history... | 2006-01-01 | |

Yu, Zhou | Misleading comparisons of homeownership rates between groups and over time: the effects of variable household formation | Despite ominous signs of housing market stress, the homeownership rate reached an all time high in 2006. We seek to understand whether the conventional definition of homeownership, which is based on the share of households and ignores the effects of variable household formation, has confounded the a... | 2009 | |

Zimmer, Zachary | Family size and support of older adults in urban and rural China: current effects and future implications | China will experience rapid growth in the proportion and number of older people in its population in the near future as a consequence of an extraordinarily rapid decline in fertility over the past several decades. Total fertility rates were as high as 7.5 in the early 1950s, but have fallen to below... | Urban China; Rural China; Support; Older adults; One-child policy | 2003 |

Regehr, John | Finding and understanding bugs in C compilers | Compilers should be correct. To improve the quality of C compilers, we created Csmith, a randomized test-case generation tool, and spent three years using it to find compiler bugs. During this period we reported more than 325 previously unknown bugs to compiler developers. Every compiler we tested w... | 2011-01-01 | |

Nichols, Shaun | Normativity and epistemic intuitions | In this paper we propose to argue for two claims. The first is that a sizable group of epistemological projects -- a group which includes much of what has been done in epistemology in the analytic tradition -- would be seriously undermined if one or more of a cluster of empirical hypotheses about ep... | Epistemology; Intuition; Empirical hypotheses | 2001 |

Stevens, Kenneth | Characterization of asynchronous templates for integration into clocked CAD flows | Asynchronous circuit design can result in substantial benefits of reduced power, improved performance, and high modularity. However, asynchronous design styles are largely incompatible with clocked CAD, which has prevented wide-scale adoption. The key incompatibility is timing. Thus most commercial... | 2009 | |

Lohse, Keith R. | Modeling Longitudinal Outcomes: A Contrast of Two Methods | Background: Repeated measures analysis of variance (ANOVA) is frequently used to model longitudinal data but does not appropriately account for within-person correlations over time, does not explicitly model time, and cannot flexibly handle missing data. In contrast, mixed-effects regression address... | mixed-effects regression; ANOVA; learning; development | |

Lindstrom, Gary E. | Object-oriented programming in scheme with first-class modules and operator-based inheritance | We characterize object-oriented programming as structuring and manipulating a uniform space of first-class values representing modules, a distillation of the notion of classes. Operators over modules individually achieve effects such as encapsulation, sharing, and static binding. A variety of idioms... | First-class modules; Operator-based inheritance | 1995 |

Kukathas, Chandran | Cultural contradictions of socialism | While no one has yet announced the death of capitalism, reports of its imminent demise have been as numerous as they have been exaggerated. Such reports have usually been bolstered by thoughtful analyses of the fundamental contradictions of capitalism, which was expected to come sliding-if not crash... | Economic systems; Social organization | 2002-11-22 |
