Partial least squares path modeling (PLS-PM) has become very popular in recent years, for measuring concepts that depend on different aspects and that are based on different types of relationships. PLS-PM represents a useful tool to explore relationships and to analyze the influence of the different aspects on the complex phenomenon analyzed. In particular, the use of higher-order constructs has allowed researchers to extend the application of PLS-PM to more advanced and complex models. In this work, our attention is focused on higher-order constructs that include reflective or formative relationships. Even if the dispute between formative models and reflective models is not exactly recent, it is still alive in current literature, for the most part within the context of structural equation models. This paper focuses attention on theoretical and mathematical differences between formative and reflective measurement models within the context of the PLS-PM approach. A simulation study is proposed in order to show how these approaches fit well in different modeling situations. The approaches have been compared using empirical application in a sustainability context. The findings from the simulation and the empirical application can help researchers to estimate and to use the higher-order PLS-PM approach in reflective and formative type models.
The concept of Regional Competitiveness (RC), in the last years, had a considerable influence on the development of strategies and policies focused on sub-national areas from an economic and social perspective. In particular, RC attracted the substantial attention of policymakers due to the possibility of evaluating and comparing different territories without any established political or conceptual framework. Conversely, scholars have long debated the meaningfulness of territorial competitiveness itself and, in case, which dimensions have to be included. This study reviewed the most recent scientific literature concerning RC with a bibliometric approach based on topic modelling. The use of a textual-based statistical approach offered an interesting insight into the RC research domain. We highlighted the topics discussed by scholars, showing the patterns emerging across years and from different publication types, and marked the differences between the vocabulary used by authors coming from EU and non-EU countries. Finally, a comparison between the RC issues coming from the literature analysis with the RC issues defined by policymakers tried to link the two standpoints followed by the institutions and the academia in a more comprehensive conceptual framework.

Only a few reports in the literature have described the use of specific instruments for assessing the quality of life in adolescents and young adults with cleft lip and palate (CLP). This condition markedly affects their lifestyle, even after surgical treatment. In the present study, we aimed to develop a quality-of-life assessment tool specifically designed for such patients with CLP. Our multidisciplinary team created a questionnaire focused on the physical, psychological, and social satisfaction of adolescents and young adults with CLP, which was adapted from 3 dimensions of the 36-item Short-Form Health Survey. The questionnaire was administered to a randomized sample of 40 adolescents and young adults (aged 16-24 years) with CLP who had completed treatment protocols and 40 (aged 16-24 years) who were not affected by CLP. The statistical results stated that the questionnaire had good reliability and validity; the Cronbach α coefficient was found to be 0.944. Moreover, factorial analysis confirmed the presence of 3 subscales that were the fundamental components of this questionnaire, which is consistent with the areas theoretically proposed and from which the items were designed and selected. Thus, we validated our novel questionnaire that was administered in the present study and proved its consistency. However, further investigations on a larger population would be useful to confirm these findings.
