Information on the relative importance of various sources of income for the aged in 1067 is available from recent tabulations of the 1968 Survey of the Demographic and Economic Characteristics of the Aged (DECA) .l From them one can answer such questions as how many beneficiaries aged 65 and over had at least half their income from social security benefits or how many of the aged had almost all...

A measure of relative importance of network effects in the stochastic actor-oriented model (SAOM) is proposed. The SAOM is a parametric model for statistical inference in longitudinal social networks. The complexity of the model makes the interpretation of inferred results difficult. So far, the focus is on significance tests while the relative importance of effects is usually ignored. Indeed, ...

This paper presents a detailed comparison of the relative importance of allowing concurrent writers versus the choice of the underlying consistency model. Our comparison is based on singleand multiple-writerversions of a lazy release consistent (LRC) protocol, and a single-writer sequentially consistent protocol, all implemented in the CVM software distributed shared memory system. We find that...

Configuration design of mechanical systems corresponds to finding the placement of a set of components such that performance criteria are optimized while satisfying design constraints. In this paper, the configuration design of a midsize truck for optimum vehicle dynamic behavior, survivability, and maintainability is considered within a multi-criteria decision making framework in which decisio...

We study the effect of providing relative performance feedback information on performance under piece-rate incentives. A natural experiment that took place in a high school offers an unusual opportunity to test this effect in a real-effort setting. For one year only, students received information that allowed them to know whether they were performing above (below) the class average as well as t...

This work proposes a new extractive text-summarization algorithm based on the importance of the topics contained in a document. The basic ideas of the proposed algorithm are as follows. At first the document is partitioned by using the TextTiling algorithm, which identifies topics (coherent segments of text) based on the TF-IDF metric. Then for each topic the algorithm computes a measure of its...

BACKGROUND Although several environmental factors predict mammographic density, estimates of its heritability have been quite high. We investigated whether part of the presumed heritability might be attributed to differential sharing of modifiable risk factors in monozygotic (MZ) and dizygotic (DZ) twins. METHODS We measured percent and absolute mammographic density using mammograms from 257 ...

We consider the problem of image annotations that takes into account of the relative visual importance of tags. Previous works usually consider the tags associated with an image as an unordered set of object names. In contrast, we exploit the implicit cues about the relative importance of objects mentioned by the tags. For example, important objects tend to be mentioned first in a list of tags....

The relative importance of meaning (semantic context) and spaces between words during reading was investigated. Sub jects read paragraphs of coherent or incoherent text aloud; some paragraphs were presented normally, others with spaces between words removed. Coherent paragraphs were taken from a short story. Incoherent paragraphs had the same words and punctuation as the coherent paragraphs, bu...
