The object of this paper is to present the results of the' study of cerebrospinal fluid examination with a view to estimating its role in diagnosis. C.S.F. examination in 105 cases in which nervous system involvement was suspected was undertaken, and the results of this examination were studied with special reference to the clinical diagnosis. These cases were followed till a final diagnosis wa...

We prove that Thompson's group F is not minimally almost convex with respect to any generating set which is a subset of the standard infinite generating set for F and which contains x1. We use this to show that F is not almost convex with respect to any generating set which is a subset of the standard infinite generating set, generalizing results in [HST].

The curvature of utility functions varies between people. We suggest that there exists a relationship between the mode in which a person usually makes a decision and the curvature of the individual utility function. In a deliberate decision mode, a decisionmaker tends to have a nearly linear utility function. In an intuitive decision mode, the utility function is more curved. In our experiment ...

In this paper, we propose a measure of individual investor sentiment that is derived from the market for bank-issued warrants. Due to a unique warrant transaction data set from a large discount broker we are able to calculate a daily sentiment measure and test whether individual investor sentiment is related to daily stock returns by using vector autoregressive models and Granger causality test...

This paper reports a study that challenges the widely-held assumption that security and functionality are a tradeoff relationship. Based on a survey sample of more than 9000 French firms, the study finds that higher degrees of system functionality entail higher degrees of security. Rather than sharing a tradeoff relation in which more security investments entail an opportunity cost in terms of ...

So far in the course we have been concerned almost exclusively with functions on the set {−1, 1}n (sometimes written F2 ). What about other product spaces? As alluded to in Problem #1 on Homeworks #4 and #5, we can develop some kind of “orthogonal decomposition” for functions on any product probability space X. This will give us some subset of our Fourier analysis, and it’s useful when one does...

Thanks to Web 2.0, retail websites and online communities provide user reviews to help consumers make purchase decisions. Current IS and marketing literature reveal that user reviews can form strong social influence on consumers’ purchase decisions. However, few studies systematically examined how social influence is developed from user reviews. To bridge the gap, our research explores what fac...
