OBJECTIVE The purpose of this study was to evaluate grouping schemes for exposure to total dust in cement industry workers using non-repeated measurement data. METHODS In total, 2370 total dust measurements taken from nine Portland cement factories in 1995-2009 were analyzed. Various grouping schemes were generated based on work process, job, factory, or average exposure. To characterize vari...

The importance of Ludwik Hirszfeld's contributions to our knowledge of the ABO blood group system has been affirmed in various ways: by Karl Landsteiner (1931) in his Nobel Address, by Hirszfeld's election to the Presidency of the Blood Group Section of the Second International Congress of Blood Transfusion (Paris, 1937), and by the naming in his memory of the Hirszfeld Microbiological Institut...

The incidence of maternal Rh immunization in Rh-negative women following a single ABO compatible Rh-positive pregnancy is about 17%. This incidence was determined by following Rh-negative women through two Rh-incompatible pregnancies and analysing their sera for anti-Rh at the time of delivery of their second observed pregnancy. Maternal Rh immunization occurs almost exclusively after delivery;...

This paper examines and proposes a list of attributes of Total Quality Management (TQM) in an educational institute, and develops a model for the benefit of researchers and academicians. Even though there have been a large number of papers published related to TQM, none of the papers focused on documenting the attributes of TQM in educational institutes using statistical methods. The paper inve...

The study discusses the role of prosodic grouping in the Mandarin Relative Clause attachment disambiguation. The grouping effect is explored under the Implicit Prosody Hypothesis (IPH) from four aspects of sentence processing experiments: default production, contrast production, online processing, as well as offline processing. It is found that (1) the length of RC greatly impacts ambiguity res...

During the last decade an enormous amount of biological data has been generated and techniques and tools to analyze this data have been developed. Many of these tools use some form of grouping and are used in, for instance, data integration, data cleaning, prediction of protein functionality, and correlation of genes based on microarray data. A number of aspects influence the quality of the gro...

To minimize cargo theft during transport, mobile radio frequency identification (RFID) grouping proof methods are generally employed to ensure the integrity of entire cargo loads. However, conventional grouping proofs cannot simultaneously generate grouping proofs for a specific group of RFID tags. The most serious problem of these methods is that nonexistent tags are included in the grouping p...

Profitability of different grouping criteria was simulated in a dairy farm with 153 lactating cows that were divided into three groups of high (79), medium (40) and low (34) cows based on the milk records. Animals were reassigned to the new groups based on the following criteria using a decision support tool and the same three groups scenario: fat corrected milk 4%, days in milk (DIM), dairy me...
