Socially desirable responding:enhancement and denial in 20 countries
2015
This article investigated the dimensionality, measurement invariance, and cross-cultural variations of social desirability. A total of 3,471 university students from 20 countries completed an adapted version of the Marlowe–Crowne scale. A two-dimensional structure was revealed in the pooled sample, distinguishing enhancement (endorsement of positive self-description) and denial (rejection of negative self-description). The factor structure was supported in most countries; medium-sized item bias was found in two denial items. In a multilevel analysis, we found that (a) there was more cross-cultural variation in denial than enhancement; (b) females tended to score higher on enhancement where…

Assessment wine aroma persistence by using an in vivo PTR-ToF-MS approach and its relationship with salivary parameters
2019
To better understand wine aroma persistence, the nasal cavity of nine volunteers was monitored by Proton Transfer Reaction-Time of Flight-Mass Spectrometry (PTR-ToF-MS) after they rinsed their mouths with three rosé wines (one control and the same wine supplemented with two tannin extracts) during four minutes. Wines were aromatised with a mixture of five target aroma compounds. Results showed that wine aroma persistence was highly compound-dependent: while esters disappeared very fast, other compounds such as linalool remained in the oral cavity for longer times after wine expectoration. A low effect of tannins (at 50 mg/L) on nasal cavity parameters was observed, with the exception for th…
Assisted Self-Adapted Testing: A Comparative Study
2004
Abstract: A new type of self-adapted test (S-AT), called Assisted Self-Adapted Test (AS-AT), is presented. It differs from an ordinary S-AT in that prior to selecting the difficulty category, the computer advises examinees on their best difficulty category choice, based on their previous performance. Three tests (computerized adaptive test, AS-AT, and S-AT) were compared regarding both their psychometric (precision and efficiency) and psychological (anxiety) characteristics. Tests were applied in an actual assessment situation, in which test scores determined 20% of term grades. A sample of 173 high school students participated. Neither differences in posttest anxiety nor ability were obta…
The Big Five Study in SLA: Future Directions and Pedagogical Implications
2020
This chapter is an attempt to integrate the existing theoretical and empirical study on personality traits in SLA in order to consider possible future research directions related to the scrutiny of isolated traits. For this reason, it commences with an outline of existing empirical findings on the role of each trait in the process of foreign language learning. On the basis of the findings, an outlook on future investigation is proposed, followed by an attempt to depict the cluster of traits that might be included to describe the characteristics of the ideal L2 achiever. In the next step, an outline of pedagogical interventions is included. It addresses ways in which specific strengths ident…
Families of Two-dimensional Vector Fields
1998
In this section we will consider individual vector fields. They can be considered as 0-parameter families. We assume these vector fields to be of class at least C 1. This will be sufficient to ensure the existence and uniqueness of the flow φ(t, x) (t is time, x ∈ S, the phase space) and the qualitative properties which we mention below.
Psychometric Aspects of the Depressive Experiences Questionnaire: Implications for Clinical Assessment and Research
2018
The Depressive Experiences Questionnaire (DEQ) is a self-report measure that assesses self-criticism and dependency, 2 personality traits that confer vulnerability to depression (Blatt, 2004). Over several decades, different, shortened versions of the DEQ have been constructed to offer an alternative to the complex scoring procedure of the original DEQ. This study explores the factor structure as well as the construct and convergent validity of the DEQ by comparing a clinical and nonclinical sample. We also compared the original DEQ with 5 shortened versions. There were 621 participants (358 university students and 263 outpatients). Fit indexes for models of the original DEQ did not meet mi…
This Is Not Vivian. The Photographer as a Form of Life
2019
In Semiotics, the notion of form of life seems to be associated to crossing a boundary, be it the one between dimensions of language (usage/rule), between cognitive aspects of a discourse (ethical/aesthetic) or generic dimensions of living (particular/general) in such a way that its own perception (and therefore its heuristic relevance) seems subordinate to the possibility of comparing those that initially appear to us as heterogeneous textualities. In order to detect the form of life it is necessary to go beyond the text, whether this leads to a practice or another text, and therefore a discourse. But is there a possibility that a text does not limit itself to speaking about a form of life…
Molecular regulation of lifespan extension in fertile ant workers.
2021
The evolution of sociality in insects caused a divergence in lifespan between reproductive and non-reproductive castes. Ant queens can live for decades, while most workers survive only weeks to a few years. In most organisms, longevity is traded-off with reproduction, but in social insects, these two life-history traits are positively linked. Once fertility is induced in workers, e.g. by queen removal, worker lifespan increases. The molecular regulation of this positive link between fecundity and longevity and generally the molecular underpinnings of caste-specific senescence are not well understood. Here, we investigate the transcriptomic regulation of lifespan and reproduction in fat bod…
Metagenomic, microbiological, chemical and sensory profiling of Caciocavallo Podolico Lucano cheese
2023
In this study, Caciocavallo Podolico Lucano (CPL) cheese was deeply characterized for its bacterial community, chemical composition and sensory aspects. The entire cheese making process (from milk collection to ripened cheese) was performed by strictly applying the traditional protocol for CPL production in four dairy factories (A–D) representative of the production area. The vat made of wood represents the main transformation tool for CPL cheese production and the biofilms hosted onto the internal surfaces of all vats analyzed in this study were dominated by lactic acid bacteria. Total mesophilic microorganisms present in bulk milk (4.7–5.0 log CFU/ml) increased consistently after contact …
