This paper investigates the relationship between social capital of married women and their fertility as well as distribution of fertility along urban regions. For this purpose, a sample of 384 women aged 20-50 were interviewed in Sabzevar. The index of dependent variable was CEB. Social capital concept was operationalized through its objective component – formal membership in social networks. S...
Spectral learning recently generated lots of excitement in machine learning, largely because it is the first known method to produce consistent estimates (under suitable conditions) for several latent variable models. In contrast, maximum likelihood estimates may get trapped in local optima due to the non-convex nature of the likelihood function of latent variable models. In this paper, we do a...
INTRODUCTION High levels of rheumatoid factors (RF) are detectable in serum of the majority of patients with rheumatoid arthritis (RA), but 5-10% of patients remain seronegative (SN). Despite clinical and genetic similarities between these two subsets of RA, it has been proposed that they may be regarded as distinct clinical entities. METHODS In the present study a panel of monoclonal antibod...
The (randomized) real-valued negative selection algorithm is an anomaly detection approach, inspired by the negative selection immune system principle. The algorithm was proposed to overcome scaling problems inherent in the hamming shape-space negative selection algorithm. In this paper, we investigate termination behavior of the realvalued negative selection algorithm with variable-sized detec...
