A time series (t = 921) of weekly survey data on vote intentions in the Netherlands for the period 1978-1995 shows that the percentage of undecided voters follows a cyclical pattern over the election calendar. The otherwise substantial percentage of undecided voters decreases sharply in weeks leading up to an election and gradually increases afterwards. This article models the dynamics of this ...

The paper presents interval-affine Gaussian algorithm for the interval linear systemsAx = b subject to some constraints on real matrices A from the interval matrix A. The interval-affine method is based on the so-called interval-affine arithmetic that allows to take the constraints into account during the computation of interval enclosures of the united solution set of the system Ax = b, and to...

Background. Use of statistical process control (SPC) in healthcare is increasing but remains less common than in other industries. Healthcare-associated infections (HAIs) are important applications that can benefit from SPC methods, including use within existing surveillance programs to trigger investigation and intervention. The empirical value of SPC, however, typically is anecdotal and remai...

Abstract Commercial producers raising centrarchids in Arkansas routinely report winter mortality. Juvenile are susceptible to harsh conditions. The Coppernose Bluegill Lepomis macrochirus purpurescens is a popular sport fish for recreational fishing, and there no recommended best management practices feeding of this species. An outdoor trial was conducted investigate the effect different regime...

liquid paraffin has been suggested as a good laxative comparing to lactulose as a treatment option in pediatric constipation. this study was performed to compare liquid paraffin with lactulose in pediatric constipation. a total of 247 patients (127 males and 120 females) aged 2-12 years (mean 4.1 ± 2.7 years) with chronic functional constipation were included in an 8 week, randomized, controlle...

Improvements in methodologies for measuring and capturing data for the UK’s sustainability indicators (social, economic and environmental) means there is now a wealth of accurate and reliable approaches to assess sustainability levels. However the majority of these indicators focus on one aspect of sustainability at a time. An understanding of these issues in a unified approach is required. Thi...

We present some new criteria for the feasibility of the interval Cholesky method. In particular, we relate this feasibility to that of the interval Gaussian algorithm.

We examined the effects of sex steroids on cognitive functioning by exogenously manipulating circulating T levels in a group of healthy young men. Thirty-two men were randomized to receive 8 wk of treatment including: 1) im T enanthate 100 mg/wk plus daily oral placebo (T); 2) im placebo/wk plus 125 microg daily oral levonorgestrel (LNG); 3) im T enanthate 100 mg/wk plus 125 microg daily oral L...
