Quick and dirty but still pretty good: a review of new descriptive methods in food science
2012
Summary For food scientists and industrials, descriptive profiling is an essential tool that involves the evaluation of both the qualitative and quantitative sensory characteristics of a product by a panel. Recently, in response to industrial demands to develop faster and more cost-effective methods of descriptive analysis, several methods have been offered as alternatives to conventional profiling. These methods can be classified in three families: (i) verbal-based methods (flash profile and check-all-that-apply), (ii) similarity-based methods (free sorting task and projective mapping aka Napping®) and (iii) reference-based methods (polarised sensory positioning and pivot profile). We succ…
Teaching Media and Methods in Marketing: European and North American Universities
2009
This article aims to examine the most widely used teaching media and methods in university education. To achieve this objective, international research has been carried out among 135 marketing teachers from North American and European universities. The study shows that North American teachers use more traditional media and participatory methods than European teachers.
QUALITY COMPETITIVENESS OF LATVIA’S METAL INDUSTRY IN THE IRON AND STEEL PRODUCT GROUPS
2012
The aim of this paper is to develop framework for evaluation of quality competitiveness of countries exports and to use this framework to examine quality competitiveness of Latvia’s metal industry in the iron and steel product groups. To achieve this aim authors studied topic related scientific literature and used appropriate methods to examine quality competitiveness according to the other researchers and authors own developed approach. To successfully achieve the aim of the paper and fulfill the tasks set the following research methods were used: 1) monographs method; 2) logical - constructive; 3) statistical analysis techniques: structural analysis and regression analysis; 4) graphical m…
Pesticide occurrence in the waters of Júcar River, Spain from different farming landscapes.
2017
A combined methodology to identify and quantify farming chemicals in the entire Júcar River basin has been developed. The procedure consisted of the application of environmental forensic criteria associating laboratory analytical samples, cartographic analysis using Geographical Information Systems (GIS) and synthetic statistical analysis. Sampling involved the collection of 15 samples in surface waters distributed alongside the Júcar River and its two main tributaries (Cabriel and Magro Rivers). The analytical procedure involves generic sample extraction and selective determination of up to 50 target pesticides by liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS). Geogra…

Are Ocular Response Analyzer useful to measure corneal hysteresis in patients with intracorneal rings?
2008
Purpose Corneal hysteresis is a viscoelastic property characterized by the difference in behavior under loading and unloading. The aim of the study was to determine corneal hysteresis in different eyes: healthy eyes, keratoconic eyes and keratoconic eyes after intracorneal ring implants. Methods This study comprised 95 eyes of 59 patients. The study population was divided into 3 groups. We analyze 30 healthy human eyes, 35 keratoconic eyes (Amsler grade II-III) and 30 keratoconic eyes after intracorneal rings implantation. Corneal biomechanical properties of these eyes were measured with the Ocular Response Analyser (ORA-Reichert) according to two parameters: corneal hysteresis (CH) and cor…
Analysis of the XENON100 dark matter search data
2014
The XENON100 experiment, situated in the Laboratori Nazionali del Gran Sasso, aims at the direct detection of dark matter in the form of weakly interacting massive particles (WIMPs), based on their interactions with xenon nuclei in an ultra low background dual-phase time projection chamber. This paper describes the general methods developed for the analysis of the XENON100 data. These methods have been used in the 100.9 and 224.6 live days science runs from which results on spin-independent elastic, spin-dependent elastic and inelastic WIMP-nucleon cross-sections have already been reported.
Using Discharge Abstracts to Evaluate a Regional Perinatal Network: Assessment of the Linkage Procedure of Anonymous Data
2008
To assess the Burgundy perinatal network (18 obstetrical units; 18 500 births per year), discharge abstracts and additional data were collected for all mothers and newborns. In accordance with French law, data were rendered anonymous before statistical analysis, and were linked to patients using a specific procedure. This procedure allowed data concerning each mother to be linked to those for her newborn(s). This study showed that all mothers and newborns were included in the regional database; the data for all mothers were linked to those for their infant(s) in all cases. Additional data (gestational age) were obtained for 99.9% of newborns.
Immigrant status, gender, and school burnout in Finnish lower secondary school students : A longitudinal study
2017
The aim of this longitudinal study among 9223 students from grade 7 and grade 9 (age 13–14 and 15–16) was to assess whether immigrant status and gender are associated with the level and change (slope) in school burnout among lower secondary school students in the Helsinki metropolitan area. Ninety-seven percent of the variation in school burnout was attributable to individual factors. Both the intercept (2.3, p < 0.001) and slope (0.5, p < 0.001) of school burnout were statistically significant. The slope showed increasing school burnout from grades 7–9. School burnout increased more in girls than in boys. Initially apparent higher school burnout among students who had immigrated to …
Concentration and reference interval of trace elements in human hair from students living in Palermo, Sicily (Italy).
2010
Trace element contents in specimens of hair collected from 137 children aged 11–13 years old, living in Palermo (Sicily, Italy) were determined by ICP-MS. This work reports analytical data for the following 19 elements: Al, As, Ba, Cd, Co, Cr, Cu, Li, Mn, Mo, Ni, Pb, Rb, Sb, Se, Sr, U, V and Zn. The most abundant chemical elements were zinc and copper (Zn > Cu), with concentrations exceeding 10microg/g (Zn = 189.2microg/g; Cu= 22.9microg/g). Other elements with concentrations greater than 1microg/g were, in order of abundance, Al > Sr > Ba > Pb. The remaining elements were all below 1microg/g. The average elemental concentrations in hair were statistically compared by Kolmogorov–Smirnov’s t…
