Could selection tests detect the future performance of descriptive panellists ?

1996

Abstract This paper discusses the appropriateness of screening tests in explaining descriptive panellist performances. It is based on a case study aimed at forming a descriptive panel capable of flavour profiling Camembert cheeses. Eighteen subjects were selected using four sensory tasks evaluating smell sensitivities, olfactory knowledge, odour memory and descriptive ability. Three additional tests were proposed during the 45 hour training to evaluate the recognition memory for odours, the concentration and the verbal creativity abilities. Panellist performances were determined on repeatability and discrimination abilities, and on the complexity of the individual sensory space. Some signif…

Monod-based ‘single-data’ strategy for biodegradation screening tests

2020

Environmental contextObtaining biodegradation data over time can be difficult, especially when dealing with environmental compartments of increasing complexity. We evaluated the possibility of obtaining a full biodegradation depletion curve from a single biodegradation-time experimental measurement, and found that environmental information related to potential chemical persistence can be derived. The applicability of this ‘single-data’ strategy is illustrated using simulated and experimental data for several compounds. AbstractInformation obtained from biodegradability tests, e.g. half-life (t50) or kinetics parameters, is relevant in environmental risk assessment of new chemicals. In thes…

Is Small Still Beautiful for the Strengths and Difficulties Questionnaire? Novel Findings Using Exploratory Structural Equation Modeling.

2020

Article first published online: June 17, 2018 During the present decade a large body of research has employed confirmatory factor analysis (CFA) to evaluate the factor structure of the Strengths and Difficulties Questionnaire (SDQ) across multiple languages and cultures. However, because CFA can produce strongly biased estimations when the population cross-loadings differ meaningfully from zero, it may not be the most appropriate framework to model the SDQ responses. With this in mind, the current study sought to assess the factorial structure of the SDQ using the more flexible exploratory structural equation modeling approach. Using a large-scale Spanish sample composed of 67,253 youths ag…

Assessing Procrastination

2019

Abstract. The short form of the General Procrastination Scale (GPS-K; Klingsieck & Fries, 2012 ; Lay, 1986 ) is a reliable self-report scale measuring general procrastination. The presumed one-dimensional factor structure of the scale, however, has never been examined. Thus, the purposes of this representative study were to examine its dimensionality and factorial invariance across age and sex, and to provide norm values of the German general population. The GPS-K was administered to a representative community sample ( N = 2,527; age range 14–95 years). A confirmatory factor analysis (CFA) was conducted. To explore convergent validity, standardized scales of distress and life satisfact…

Psychometric properties and validation of the sexual sensation seeking scale in Spanish adolescents: Brief screening method for use in research and c…

2018

Abstract Sexual sensation seeking among adolescents has been mostly associated with unprotected sex and other risky behaviors. This paper presents the Spanish adaptation and validation of the Sexual Sensation Seeking Scale (SSSS). This cross-sectional study included 1350 adolescents (601 male and 749 female), aged between 15 and 18 years ( M  = 16.1, SD  = 0.97). Exploratory Factor Analysis (EFA) yielded two components: Physical Sensations Attraction (PSA), and New Experiences Seeking (NES), which together accounted for 48.98% of the total variance. That structure was later verified through Confirmatory Factor Analysis (CFA). Internal consistency was 0.82 for the total scale, and 0.76 and 0…

Television in the bedroom and increased body weight: potential explanations for their relationship among European schoolchildren

2012

Summary Aims: A television in the bedroom is associated with measures of adiposity. We aimed to test if this association is mediated by any of (i) time spent watching television, (ii) sleep duration, (iii) physical activity level or (iv) consumption of soft drinks. Method: Data were from 7234 boys and girls aged 10–12 years in European countries involved in the EuropeaN Energy balance Research to prevent excessive weight Gain among Youth project (Belgium, Greece, Hungary, the Netherlands, Norway, Slovenia and Spain). Waist circumference, height and weight were measured. The presence of a bedroom television, television viewing time, sleep duration, physical activity time and soft drink consu…

SYNTHESIS AND ANTITUMOR ACTIVITY OF 2,5-BIS(3'-INDOLYL)-FURANS AND 3,5-BIS(3'-INDOLIY)-ISOXAZOLES, NORTOPSENTIN ANALOGUES

2010

Abstract A series of novel 2,5-bis(3′-indolyl)furans and 3,5-bis(3′-indolyl)isoxazoles were synthesized as antitumor agents. The antiproliferative activity was evaluated in vitro toward diverse human tumor cell lines. Initially 5 isoxazoles and 3 furan derivatives were tested against a panel of 10 human tumor cell lines and the most active derivatives 3c and 4a were selected to be evaluated in an extended panel of 29 cell lines. By exhibiting mean IC50 values of 17.4 μg/mL (3a) and 20.5 μg/mL (4c), in particular 4c showed a high level of tumor selectivity toward the 29 cell lines.
