SYLL/SEC AND SEC/SYLL SCORES ARE NOT EQUIVALENT, EVEN IF THEY COME FROM THE SAME TEST The diagnosis of developmental dyslexia requires measures of reading ability to be at least two standard deviations (SD) below age mean, encompassing accuracy, speed, and comprehension (ICD10, WHO, 1992). Reading speed is typically measured in either seconds per syllable (sec/syll) or syllables per second (syl...

SIR—We congratulate Healey and colleagues on their recent publication in Age and Ageing on the prevention of falls in the hospital setting [1]. As researchers in this field we appreciate the difficulties faced when attempting to implement falls prevention interventions and conduct research in this challenging setting with little or no additional funding. Previous trials of similar size investig...

The paper by E. } . Charny ("Psychosomatic Manifestations of Rapport in Psychotherapy") which follows in this issue is not a psychosomatic study in the traditional sense. Charny does not assess psychological states or measure and correlate physiological variables as is usually done. Yet obviously there is some cogent reason for his work to have been published in PSYCHOSOMATIC MEDICINE. Nor can ...

This paper describes a green analytical procedure for the determination of bumetanide using diffuse reflectance spectroscopy. The proposed method is based on reflectance measurements of a violet compound produced from a spot test reaction between bumetanide and p-dimethylaminocinnamaldehyde (p-DAC) in an acid medium, using filter paper as a solid support. The best conditions for the reaction ha...

A uctions have captured the attention of economists for several reasons. One is the relevance for specific applications of research on auctions in light of their widespread and growing use in the field, particularly in online transactions. Auctions are also highly amenable to economic analysis, because the rules are generally precisely defined; modern game-theoretic techniques of economic analy...

Reporting effect sizes in scientific articles is increasingly widespread and encouraged by journals; however, choosing an effect size for analyses such as mixed-effects regression modeling and hierarchical linear modeling can be difficult. One relatively uncommon, but very informative, standardized measure of effect size is Cohen's f(2), which allows an evaluation of local effect size, i.e., on...

In this paper, we consider some statistical aspects of inverse problems. using Bayesian analysis, particularly estimation and hypothesis-testing questions for parameterdependent differential equations. We relate Bayesian maximum likelihood Io Tikhonw regularization. and we apply the expectatian-minimization (F-M) algorithm to the problem of setting regularization levels. Further, we compare Bay...

The development, optimization, and analysis of downstream processes are challenged by a high number of potentially critical process parameters that need to be investigated using lab-scale experiments. These process parameters are spread across multiple unit operations and potentially show interactions across unit operations. In this contribution, we present a novel strategy for bioprocess devel...

background: it is known that dental unit waterline can be a source of infection. the aim of this study was to evaluate the effi cacy of a mouthwash, chlorhexidine, in controlling microbial and fungal contamination of dental unit waterlines. materials and methods: in the present experimental study, the water in high-speed handpieces and air/water syringes of 35 dental units in a dental school wa...
