Experimental and natural cathodoluminescence in the shell of Crassostrea gigas from Thau lagoon (France): ecological and environmental implications.
2006
We present a cathodoluminescence (CL) study of growth layer deposition in the shell of the oyster Crassostrea gigas. CL is based on the physical properties of lattice-bound manganese (Mn2+), which is the main activator in calcium carbonate. Our study involved chemical marking by immersing individuals in seawater to which manganese chloride had been added, and subsequent reading of the shell with CL microscopy coupled with numeric treatment of microphotographs; CL emission was analyzed using a scanning electron microscope coupled to a spectrometer. Since the marking did not harm the oysters, repeated markings were possible, allowing validation of the inferences made from analysis of the shel…
Psychometric properties of the Satisfaction with Job Life Scale in Portuguese workers: A systematic study based on the IRT and CFA modeling
2020
Job satisfaction is related to better physical and mental health, as well as to factors specifically related to work. In this context, the measurement of work satisfaction is important for organizations that profess an interest in engaged and satisfied workers. Therefore, this study aims to examine the psychometric properties of the Satisfaction with Job Life Scale (SWJLS) in Portuguese workers by combining the procedures of the Classical Test Theory (CTT) and the Item Response Theory (IRT). Specifically, internal structure of the scale was studied, its reliability (consistency), correlations with other measures of wellbeing (life satisfaction, loneliness, emotional wellbeing at work, and j…
The population genomics of archaeological transition in west Iberia: Investigation of ancient substructure using imputation and haplotype-based metho…
2017
We analyse new genomic data (0.05–2.95x) from 14 ancient individuals from Portugal distributed from the Middle Neolithic (4200–3500 BC) to the Middle Bronze Age (1740–1430 BC) and impute genomewide diploid genotypes in these together with published ancient Eurasians. While discontinuity is evident in the transition to agriculture across the region, sensitive haplotype-based analyses suggest a significant degree of local hunter-gatherer contribution to later Iberian Neolithic populations. A more subtle genetic influx is also apparent in the Bronze Age, detectable from analyses including haplotype sharing with both ancient and modern genomes, D-statistics and Y-chromosome lineages. However, t…
Bolton ratios in Portuguese subjects among different malocclusion groups
2018
Background Several methods have been described to estimate inter-arch tooth size relationship, such as Bolton's ratios. The aims of this study were to verify the validity of Bolton indexes in a sample of untreated Portuguese subjects based on Angle classification and to evaluate the gender difference. Material and Methods 168 pre-treatment dental casts of orthodontics Portuguese subjects (59 males and 109 females) with different occlusions were used, which were selected randomly from 541 consecutively treated orthodontic patients. The mesiodistal widths from first molar to first molar were measured on each pre-treatment cast to the nearest 0.01 mm using digital caliper, and Bolton's anterio…
Factorial Validity of the General Health Questionnaire 12 in an Angolan Sample
2017
Abstract. Most evidence available has found multidimensional solutions for the General Health Questionnaire’s (GHQ12) structure, contrary to the authors’ original one-factor solution. Recently, the study of method effects associated to negatively worded items has been included in the study of GHQ12’s factor structure, and the most common conclusion has been that the best-fitting structure is a single factor confounded by response bias. Current study analyzes the factor structure of the Portuguese version of the GHQ12. The sample consisted of 1,332 young Angolan adults. Previously-reported structures, including one-factor and multidimensional substantive ones, as well as bifactor structures…

Orlando Furioso dalla specola del costrutto causativo
2017
Analisi e riflessioni sulle ricorrenze del costrutto causativo nell'Orlando Furioso che si rivela tratto saliente della lingua e dell'espressione dell'opera. Il poema di Ariosto pullula naturalmente di attori che, osservati dalla specola del costrutto causativo, si qualificano appunto come né sovrumani né subumani. Attori siffatti ne sono i protagonisti. Le loro vicissitudini costituiscono il tema dell’opera e ne sostanziano la trama. Che il costrutto causativo sia tanto frequente nel Furioso non è dunque un accidente e il dato è a questo punto comprensibile, perché integrato in un sistema. Il costrutto causativo è nel cuore del processo narrativo, ne è un motore.
