PurposeThe Integrative Levels Classification (ILC) is a comprehensive “freely faceted” knowledge organization system not previously expressed as SKOS (Simple Knowledge Organization System). This paper reports and reflects on work converting the ILC to SKOS representation.Design/methodology/approachThe design of the ILC representation and the various steps in the conversion to SKOS are described and located within the context of previous work considering the representation of complex classification schemes in SKOS. Various issues and trade-offs emerging from the conversion are discussed. The conversion implementation employed the STELETO transformation tool.FindingsThe ILC conversion captures some of the ILC facet structure by a limited extension beyond the SKOS standard. SPARQL examples illustrate how this extension could be used to create faceted, compound descriptors when indexing or cataloguing. Basic query patterns are provided that might underpin search systems. Possible routes for reducing complexity are discussed.Originality/valueComplex classification schemes, such as the ILC, have features which are not straight forward to represent in SKOS and which extend beyond the functionality of the SKOS standard. The ILC's facet indicators are modelled as rdf:Property sub-hierarchies that accompany the SKOS RDF statements. The ILC's top-level fundamental facet relationships are modelled by extensions of the associative relationship – specialised sub-properties of skos:related. An approach for representing faceted compound descriptions in ILC and other faceted classification schemes is proposed.

Perfectionism is a crucial concept in psychology as perfectionism has been found to be related to many important factors affecting daily and academic life. Many researchers have tried to measure perfectionism since 1980. Following an extensive literature review, Smith, Saklofske, Stoeber, and Sherry developed a new perfectionism scale called Big Three Perfectionism Scale (BTPS). The present study addressed the validation study of the BTPS in Turkish sample. The factor structure of the BTPS and measurement invariance across gender groups was tested with the Turkish sample. The BTPS was administered to 609 undergraduate students studying in different departments. Reliability analyses showed that the Turkish version of the scale had an excellent internal consistency. Data from Turkey demonstrated acceptable fit to the three-factor, 10-facet structure of BTPS. The results also indicated that there was no significant difference between fit indexes of configural, metric, and scalar invariance across gender.

Heterogeneous bubble nucleation is one of the most fundamental interfacial processes that has received broad interest from diverse fields of physics and chemistry. While most studies focused on large microbubbles, here we employed a surface plasmon resonance microscopy to measure the nucleation rate constant and activation energy barrier of single nanosized embryo vapor bubbles upon heating a flat gold film with a focused laser beam. Image analysis allowed for simultaneously determining the local temperature and local nucleation rate constant from the same batch of optical images. By analyzing the dependence of nucleation rate constant on temperature, we were able to calculate the local activation energy barrier within a submicrometer spot. Scanning the substrate further led to a nucleation rate map with a spatial resolution of 100 nm, which revealed no correlation with the local roughness. These results indicate that facet structure and surface chemistry, rather than geometrical roughness, regulated the activation energy barrier for heterogeneous nucleation of embryo nanobubbles.

ABSTRACTFacet structures of GaN grown by epitaxial lateral overgrowth (ELO) via low pressure-metalorganic vapor phase epitaxy (LP-MOVPE) are controlled by growth conditions such as reactor pressure and growth temperature, where this technique is called FACELO (Facet Controlled ELO). The mechanism of the morphological change is discussed based on stability of the surface atoms. The propagation mechanism of the threading dislocations for the different GaN facet structure is also investigated. The distribution and density of the threading dislocations are observed by the growth pit density (GPD) method. Two typical models employing the FACELO are proposed; in one model, the dislocation concentrates only on the window area and, in the other model, only in the coalescence region in the center of the mask. In the latter model, the dislocation density is dramatically dropped to the order of 105−6 cm−2 with good reproducibility.

This study presents a cross-cultural validation of the recently developed Resiliency Scale for Young Adults (RSYA) with a sample of 289 Canadian university students and 259 Italian university students. The RSYA demonstrated good internal consistency across the two samples and acceptable retest reliability for the Canadian sample. Confirmatory factor analysis supported the three-factor, 10-facet structure of the RSYA, and comparison of the two country samples found metric invariance. As expected, positive correlations also emerged between resiliency and trait emotional intelligence in both samples. Finally, correlations with personality variables were explored in both samples. The present findings provide further support for the RSYA as a valid and reliable measure of personal resiliency for both Canadian and Italian young adults, and for the cross-cultural generalizability of the three-factor model of personal resiliency upon which it is based.
