We examined the association between community violence exposure and childhood asthma risk in a multilevel, multimethod, longitudinal study controlling for individual- and neighbourhood-level confounders and pathway variables. Analyses included 2,071 children aged 0-9 yrs at enrolment from the Project on Human Development in Chicago Neighborhoods. Multilevel logistic regression models estimated ...

Disparities in verbal ability, a major predictor of later life outcomes, have generated widespread debate, but few studies have been able to isolate neighborhood-level causes in a developmentally and ecologically appropriate way. This study presents longitudinal evidence from a large-scale study of >2,000 children ages 6-12 living in Chicago, along with their caretakers, who were followed where...

Virtually all previous research in verification of knowledqe bases has concentrated on rule-based systems. Since most systems and shells developed to-date have concentrated on knowledqe representation usinq rules, this seems appropriate. However, increasinqly, there are systems beinq built usinq other forms of knowledqe representation, such as frames and semantic nets. As a result, there is a n...

The present contribution reports on the observation of two diffusive relaxation modes in a concentrated microemulsion made of repulsive droplets. These two modes can be interpreted in the frame of Weissman's and Pusey's theoretical pioneering works. The fast mode is associated to the collective diffusion of droplets whereas the slow one corresponds to the relaxation of droplet concentration flu...

Inducing rules from very large datasets is one of the most challenging areas in data mining. Several approaches exist to scaling up classification rule induction to large datasets, namely data reduction and the parallelisation of classification rule induction algorithms. In the area of parallelisation of classification rule induction algorithms most of the work has been concentrated on the Top ...

This paper presents a model of price adjustment in replica economies with two consumer types and two goods. The model provides a trading rule that allows out-of-equilibrium trading and a decentralized price adjustment rule that features “learning through noisy imitation.” It is shown that for all sufficiently large economies, the process of experimentation and imitation favors adjustment of pri...

Managing extreme price fluctuations in cryptocurrency markets are of central importance for investors this market segment. Using a sample highly liquid cryptocurrencies from January 2017 to June 2021, paper proposes dynamic investment strategy that selects based on their historical volatility and is complemented by simple stop-loss rule. Our results reveal investing concentrated low portfolios ...

mulla sadra, as the founder of the transcendental philosophy, has special viewpoints on society. unlike those who believe that mulla sadra ignored society and paid his mere attention to the spiritual issues, he cared about the social situation of his time and proposed certain pathological guidelines to reform the society. in his opinion, the real problem was that those who truly deserved to rul...

blackleg in cattle has been recognized since 1938 in iran that mostly affects cattle in enzootic farm. main object of this study was to prepare and formulate a concentrated potent vaccine for immunization of cattle against blackleg in iran. experimental concentrated blackleg vaccine was prepared according to the method described by fao. the medium (modified medium for production of experimental...

Theory suggests that the effects of disadvantaged neighborhoods on child educational outcomes may depend on a family’s economic resources as well as the timing of neighborhood exposures during the course of child development. However, most previous research assumes that disadvantaged neighborhoods have the same effects on all children regardless of their family resources, and few prior studies ...
